Item 5.  Other Events.

News release dated March 23, 1998, announcing that the Company signed a 
worldwide exclusive license for O6 Benzyl Guanine (BG), a series of related 
compounds and technologies which enhance the effectiveness of a class of 
currently used chemotherapeutic agents (O6 alkylators). These technologies 
are licensed to Pacific from Pennsylvania State University on behalf of 
itself, National Institutes of Health and other universities. Multiple Phase 
I human clinical trials for the BG compounds being conducted at the 
University of Chicago, Duke University Medical Center and Case Western 
Reserve University are nearing completion in different cancer types, 
including brain, colon and renal carcinoma.

The terms of the license agreement include payments for royalties, license 
fees and milestone payments to be paid in cash or common stock of the 
Company. Some of the cash and common stock payments are contingent upon the 
achievement of certain milestones in connection with the clinical development 
and regulatory approval of the BG compounds. 

Paramount Capital Investments, LLC ("Paramount") acted as financial advisor 
to the Company in connection with the identification, negotiation and 
consummation of the license and will receive a fee in cash and securities 
vesting upon achievement of certain performance based events.  Paramount is 
affiliated with certain significant shareholders and a Director of the 
Company.

                    ARTICLE 4 - ROYALTIES AND OTHER CONSIDERATION

          4.1    For the rights, privileges and license granted hereunder, 
the Company shall pay to the Licensor as set forth below, and in accordance 
with the provisions of Articles 4.4 and 4.5, to the end of the term of the 
Patent Rights or until this License Agreement shall be terminated as 
hereinafter provided:

                 4.1.1   The Company shall pay to the Licensor non-refundable 
semi-annual royalties in an amount equal to six percent (6%) of Net Sales by 
the Company, or any Affiliate of the Company, of the Licensed Products or 
Licensed Processes covered by at least one issued and unexpired claim under 
the Patent Rights and three percent (3%) of Net Sales by the Company or any 
Affiliate of the Company covered by pending patent claims.

                 4.1.2   The Company shall pay to the Licensor semi-annual 
royalties in an amount equal to twenty two and one half percent (22.5%) of 
the royalties received by the Company or its Affiliate from sales by any 
sublicensee of Licensed Products or Licensed Processes.  In addition, the 
Company shall pay to the Licensor fifteen percent (15%) of all sublicensing 
fees or other lump sum payments or other compensation received by the Company 
or an Affiliate from its sublicensees for the use, lease or sale of Licensed 
Products and Licensed Processes; provided, however, that the Company shall 
pay to the Licensor fifty percent (50%) of lump sum payments, if any, that 
are made within six (6) months from the Execution of this Agreement and 
received by the Company or its Affiliate; provided further, however, that no 
amounts shall be due and payable to the Licensor pursuant to this paragraph 
4.1.2 on account of (a) payments made to the Company solely for bona fide 
research and development (but which shall not include option or other similar 
fees/consideration for access to or rights to the Patent Rights or Know-how 
and (b) purchases of debt or equity securities of the Company.

          4.2    On sales of Licensed Products by the Company to Affiliates 
or related parties which are end users of such Licensed Products the value of 
Net Sales attributed under this Article 4 shall be that which would have been 
received in an arms-length transaction, based on sales of like quantity and 
quality products at or about the time of such transaction.

          4.3    No multiple royalties shall be payable because the use, 
lease or sale of any Licensed Product or Licensed Process is, or shall be, 
covered by more than one valid and unexpired claim contained in the Patent 
Rights.  In addition, royalties shall be paid for a Licensed Product or 
Licensed Process based upon only one of paragraphs 4.1.1 or 4.1.2 above (that 
is, royalties on direct sales of a Licensed Product or Licensed Process by 
the Company or its Affiliates shall be based only on paragraph 4.1.1, while 
royalties on sales of a Licensed Product or Licensed Process by the Company's 
sublicensees shall be based only on paragraph 4.1.2, so as to avoid double 
counting).

          4.4    In the event that a Licensed Product is sold in the form of 
a combination product containing one or more products or technologies which 
are themselves not a Licensed Product, the Net Sales for such combination 
product shall be calculated by multiplying the sales price of such 
combination product by the fraction A/(A+B) where A is the invoice price of 
the Licensed Product or the Fair Market Value of the Licensed Product if sold 
to an Affiliate and B is

                                       7
<PAGE>

the total invoice price of the other products or technologies or the Fair 
Market Value of the other products or technologies if purchased from an 
Affiliate.  In the case of a combination product which includes one or more 
Licensed Products, the Net Sales for such combination product upon which the 
royalty due to the Licensor is based shall not be less than the normal 
aggregate Net Sales for such Licensed Product.

          4.5    Royalty payments shall be paid in United States dollars in 
New York, New York or at such other place as the Licensor may reasonably 
designate consistent with the laws and regulations controlling in any foreign 
country. Any withholding taxes which the Company, its Affiliate or any 
sublicensee shall be required by law to withhold on remittance of the royalty 
payments shall be deducted from such royalty payment to the Licensor.  The 
Company shall furnish the Licensor with the original copies of all official 
receipts for such taxes. If any currency conversion shall be required in 
connection with the payment of royalties hereunder, such conversion shall be 
made by using the exchange rate prevailing at Citibank, N.A. in New York, New 
York on the last business day of the calendar quarterly reporting period to 
which such royalty payments relate.

          4.6    Royalties payable to the Licensor shall be paid quarterly 
within sixty (60) days from the end of the fiscal quarter.  Each such payment 
shall be for unpaid royalties which accrued within or prior to the Company's 
two most recently completed fiscal quarters.

          4.7    Subject to the terms of this paragraph 4.7, the Company 
shall pay to the Licensor a non-refundable minimum annual royalty (the 
"Minimum Annual Royalty") equal to seventy-five thousand dollars ($75,000) 
per year.

                 4.7.1   The Minimum Annual Royalty shall be fully creditable 
against (a) any payments owing to the Licensor by the Company on account of 
any payments due and owing under this Article 4, which payments are earned by 
the Licensor in such year; (b) any payments in such year paid or payable 
under any CRADA and (c) any payments in such year paid or payable on account 
of Sponsored Research with any of the Co-owners.

                 4.7.2   Such minimum annual royalties shall be payable in 
accordance with paragraph 5.1.  Notwithstanding the provisions of the above 
paragraph 4.6, any payment required to be made to the Licensor to meet the 
Minimum Annual Royalty owed shall be due and payable within sixty (60) days 
from the end of each calendar year.

                 4.7.3   Notwithstanding anything else to the contrary, in 
the event that the Company is not granted access to the N.C.I. Clinical Data 
and pre-clinical data owned by N.I.H. relating to potential Licensed Products 
and Licensed Processes, then no Minimum Annual Royalty shall be due or 
payable to the Licensor until the calendar year in which the first Phase II 
clinical trial pursuant to a Company sponsored IND has commenced, thereafter, 
the Minimum Annual Royalty shall be reduced to thirty-seven thousand five 
hundred dollars ($37,500) until the First Commercial Sale.

          4.8    The Company shall pay to the Licensor the following 
milestone payments which shall be credited against or deducted from royalties 
otherwise owed or which may in the

                                       8

future be owing payable to the Licensor on account of sublicensing royalties 
and/or lump sum payments received by the Company or its Affiliate from 
sublicensees pursuant to paragraph 4.1.2:

                 4.8.1   One hundred fifty thousand dollars ($150,000) as an 
up-front licensing fee, payable upon the earlier to occur of (a) receipt by 
the Company of the N.C.I. Clinical Data and pre-clinical data or (b) the date 
that is six (6) months from the Effective Date, in accordance with paragraph 
5.1. Any shares of Common Stock (as defined below) issued to the Licensor in 
satisfaction of the payment due pursuant to this paragraph 4.8.1 shall be 
priced at the closing price per share of the Common Stock for the ten (10) 
consecutive trading days preceding (i) the execution of this Agreement and 
(ii) the date on which payment is made, whichever is lower;

                 4.8.2   Seventy-five thousand dollars ($75,000) upon 
approval of the first Company sponsored IND for any Licensed Product with the 
United States Food and Drug Administration (FDA) or its foreign equivalent, 
payable in accordance with paragraph 5.1;

                 4.8.3   One hundred fifty thousand dollars ($150,000) upon 
the date of initiation of the first Company sponsored Phase III Clinical 
Trial in the United States for a Licensed Product, payable in accordance with 
paragraph 5.1;

                 4.8.4   Two hundred fifty thousand dollars ($250,000) upon 
the filing of the first Company sponsored New Drug Application ("NDA") for a 
Licensed Product with the United States FDA or its foreign equivalent, 
payable in accordance with paragraph 5.1; and

                 4.8.5   One-million five hundred thousand dollars 
($1,500,000) upon the first final approval of a Company sponsored  NDA for a 
Licensed Product by the United States FDA or its equivalent in any Foreign 
Major Market Country, payable in accordance with paragraph 5.1.

          4.9    Notwithstanding anything in this Agreement to the contrary, 
no payment obligations shall be due with respect to any sale or sublicense 
covering any Licensed Product or Licensed Process in a country if:

                 4.9.1   There are no issued Patent Rights underlying such 
Licensed Product in such country; or

                 4.9.2   To the extent that a patent application is pending, 
there is no claim within such patent application on which a royalty herein 
can reasonably be based which has been pending for less than seven (7) years 
since the initial filing date.

          4.10   To the extent that the Company or any Affiliate of the 
Company is required, by order or judgement of any court to obtain in any 
jurisdiction any license from a third party in order to practice the rights 
purported to be granted to the Company by the Licensor hereunder under issued 
patents in such jurisdiction, then up to fifty percent (50%) of the royalties 
payable under such license in such jurisdiction may be deducted from 
royalties otherwise payable to the Licensor hereunder, provided that in no 
event shall the aggregate royalties payable to the Licensor in any 
semi-annual period in such jurisdiction be reduced by more than fifty percent 
(50%) as a result of any such deduction, provided further that any excess 
deduction remaining as a result of such limitation may be carried forward to 
subsequent periods.

          4.11   For a period of three (3) years from the date of execution 
of this Agreement the Company agrees to use its reasonable efforts to supply 
up to ten thousand dollars ($10,000)

                                       9
<PAGE>

worth of O6 Benzyl guanine to the N.C.I. at the Company's expense and 
calculated at the Company's cost.  Any requirements of O6 Benzyl guanine on 
the part of the N.C.I. in excess of such amount shall be provided to the 
N.C.I. by the Company at the Company's cost.  The Company's obligation to 
supply O6 Benzyl guanine to the N.C.I. shall terminate upon the earlier to 
occur of (a) five (5) years from the date of execution of this Agreement, (b) 
termination of this Agreement pursuant to Article 8 or (c) the establishment 
of a CRADA, which shall supersede this paragraph 4.11.


                            ARTICLE 5 - PAYMENT BY EQUITY

          5.1    The Company shall have the right, but not the obligation, to 
fulfill a portion of its payment obligations pursuant to paragraphs 4.7 and 
4.8 through the issuance of a number of shares of common stock of the Company 
(the "Common Stock") equal to the cash value of such payments; provided, 
however, that in no event shall the cash portion of any such payments be less 
than the lesser of (a) twenty-five percent (25%) of the amount due and owing 
and (b) fifty-thousand dollars ($50,000).

          5.2    For purposes of calculating the cash value of the Common 
Stock under this Article 5, the current market price of the Common Stock 
shall be deemed to be the average closing price of the Common Stock on the 
ten (10) consecutive trading days prior to (a) the date of achievement of any 
such milestone or (b) the date on which any payment pursuant to Article 4 is 
due, whichever is earlier, on the principal national securities exchange on 
which the Common Stock is admitted to trading or listed, or if not listed or 
admitted to trading on any such exchange, the representative average closing 
bid price of the Common Stock as reported by the National Association of 
Securities Dealers, Inc. Automated Quotations System ("NASDAQ"), or other 
similar organization if NASDAQ is no longer reporting such information, or, 
if the Common Stock is not reported on NASDAQ, the average per share bid 
price for the Common Stock in the over-the-counter market as reported by the 
National Quotation Bureau or similar organization, or if not so available, 
the fair market price of the Common Stock as determined by an independent 
third party accounting firm selected by the Company.

                 5.3.1   All certificates representing the Stock and, until 
such time as the Stock is sold in an offering which is registered under the 
Securities Act or the Corporation shall have received an opinion of counsel 
(including counsel for any recipient of stock hereunder) that such 
registration is not required in connection with a resale (or subsequent 
resale) of the Stock under all applicable laws, regulations and rules, all 
certificates issued in transfer thereof or substitution therefor, shall, 
where applicable, have endorsed thereon the following (or substantially 
equivalent) legends:

                  (a)    THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE
BEEN ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER 

                                       10
<PAGE>

THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAW.  SUCH 
SECURITIES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION 
OR UNLESS THE COMPANY RECEIVES AN OPINION OF COUNSEL STATING THAT SUCH SALE 
OR TRANSFER IS EXEMPT FROM THE REGISTRATION AND PROSPECTUS DELIVERY 
REQUIREMENTS OF SAID ACT UNDER ALL APPLICABLE LAWS, RULES AND REGULATIONS OR 
IS OTHERWISE IN COMPLIANCE WITH ALL APPLICABLE LAWS AND REGULATIONS.

                 (b)     Any legend required to be placed thereon by any 
applicable state securities law.

                 (c)     A legend to the effect that such shares of stock are 
subject to a License Agreement that limits the transferability of the shares 
under certain conditions and applies to any transferee of such shares.

                 5.3.2   With a view to making available to the Licensor the 
benefits of certain rules and regulations of the SEC which at any time permit 
the sale of the Common Stock to the public without registration, the Company 
shall use its reasonable efforts to:

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

                 (b)     file with the SEC in a timely manner all reports and 
other documents required of the Company under the Securities Exchange Act of 
1934 (the "Exchange Act"); and

                 (c)     so long as the Licensor owns any unregistered 
Registrable Securities, furnish to the Licensor upon any reasonable request a 
written statement by the Company as to its compliance with Rule 144 under the 
Act, and of the Exchange Act, a copy of the most recent annual or quarterly 
report of the Company, and such other reports and documents of the Company as 
the Licensor may reasonably request in availing itself of any rule or 
regulation of the Commission allowing the Licensor to sell any such 
securities without registration.

                 5.3.3   If the Common Stock is or becomes tradeable pursuant 
to Rule 144 or a similar exemption from registration then the Licensor shall 
have no right to the registration rights described in paragraph 5.5.

          5.4    The Company agrees that if, at any time, and from time to 
time, during the period commencing two (2) years after the date hereof, or 
one (1) year after the Company's next public offering of Common Stock 
registered under the Securities Act of 1933 (the "Act"), whichever is later, 
and ending on the date which is five (5) years from the date hereof, the 
Board of Directors of the Company shall authorize the filing of a 
registration statement under the Act (other than the initial public offering 
of the Company's Common Stock, or other than a registration statement on Form 
S-8, Form S-4 or any other form which does not include substantially the same 
information as would be required in a form for the general registration of 
securities) in connection with the proposed offer of any of its securities by 
it or any of its stockholders, the Company will, subject to the limitations 
set forth in paragraph 5.5 below, (i) promptly notify the Licensor that such 
registration statement will be filed and that the Common Stock then held by 
the Licensor will be

                                       11
<PAGE>

included in such registration statement at the Co-owner's request, (ii) cause 
such registration statement to cover all of such Common Stock issued to the 
Licensor requesting inclusion, (iii) use its reasonable best efforts to cause 
such registration statement to become effective as soon as practicable and 
(iv) take all other action necessary under any Federal or state law or 
regulation of any governmental authority to permit all such Common Stock 
which has been issued to the Licensor to be sold or otherwise disposed of, 
and will maintain such compliance with each such Federal and state law and 
regulation of any governmental authority for the period necessary for the 
Licensor to effect the proposed sale or other disposition.

                 5.4.1   The Licensor shall only twice have the right to 
request inclusion of any of their shares of Common Stock in a registration 
statement as described in paragraph 5.1.

          5.5    Notwithstanding paragraph 5.4 above, the Company may at any 
time, abandon or delay any registration commenced by the Company.  In the 
event of such an abandonment by the Company, the Company shall not be 
required to continue registration of shares requested by the Licensor for 
inclusion and the Licensor shall retain the right to request inclusion of 
shares pursuant to paragraph 5.4.

          5.6    The Common Stock will be acquired by the Co-owners and/or 
their designees for investment purposes only, for an indefinite period of 
time, for their own account, not as a nominee or agent for any other Entity 
(as defined in paragraph 1.2.2), and not with a view to the sale or 
distribution of all or any part thereof, and the Co-owners have no present 
intention of selling, granting any participation in, or otherwise 
distributing, any or all of the Common Stock.

                 5.6.1   The Co-owners shall provide to the Company a list of 
names of individuals and/or entities at least thirty (30) days prior to any 
sale, grant of participation in or other distribution of any Common Stock by 
the Licensor.  Any sale, grant of participation in or other distribution of 
any Common Stock by any of the Co-owners shall comply in all respects with 
the Securities Act and the Exchange Act.

          5.7    The parties agree to execute such further instruments and to 
take such further action as may reasonably be necessary to carry out the 
intent of this Article 5, and the Licensor specifically agrees to cooperate 
affirmatively with the Company, to the extent reasonably requested by the 
Company, to enforce the rights of the Company and its successors and 
assignees.

          5.8    The Licensor agrees that, in connection with each 
underwritten public offering registered under the Act of shares of Common 
Stock or other equity securities of the Company by or on behalf of the 
Company, they shall not sell, transfer or offer to sell or transfer, any 
equity securities of the Company for such period (the "Lock-up Period") as 
the managing underwriter of such offering determines is necessary to effect 
the underwritten public offering; provided, however, that the Licensor shall 
not be subject to a Lock-up Period greater than that required of the 
Company's officers and directors.  The Licensor further agrees that it will 
sign an agreement as requested by the managing underwriter of such offering 
to effect the foregoing.

          5.9    With respect to any registration statement pursuant to which 
the Licensor participates as a selling shareholder, to the extent permitted 
by law, the Company shall indemnify the Licensor and each person controlling 
the Licensor within the meaning of Section 15 of the Act, 

                                       12
<PAGE>

with respect to which any registration, qualification or compliance has been 
effected, against all claims, losses, damages and liabilities (or action 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 or offering circular, or any 
amendment or supplement thereof, 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 not misleading, in light of the circumstances 
in which they were made, and will reimburse the Licensor, and each person 
controlling the Licensor, for legal and any other expenses reasonably 
incurred in connection with investigating or defending any such claim, loss, 
damage, liability or action as incurred; provided that the Company will not 
be liable in any such case to the extent that any untrue statement or 
omission or allegation thereof is made in reliance upon and in conformity 
with written information furnished to the Company by or on behalf of the 
Licensor and stated to be specifically for use in preparation of such 
registration statement, prospectus or offering circular; provided that the 
Company will not be liable in any such case where the claim, loss, damage or 
liability arises out of or is related to the failure of the Licensor to 
comply with the covenants and agreements contained in any agreement 
respecting sales of securities of the Company, and except that the foregoing 
indemnity agreement is subject to the condition that, insofar as it relates 
to ny such untrue statement or alleged untrue statement or omission or 
alleged omission made in the preliminary prospectus but eliminated or 
remedied in the amended prospectus on file with the Commission at the time 
the registration statement becomes effective or in the amended prospectus 
filed with the Commission pursuant to Rule 424(b) or in the prospectus 
subject to completion and term sheet under Rule 434 of the Act, which 
together meet the requirements of Section 10(a) of the Act (the "Final 
Prospectus"), such indemnity agreement shall not inure to the benefit of any 
the Licensor or person controlling the Licensor, if a copy of the Final 
Prospectus furnished by the Company to the Licensor for delivery was not 
furnished to the person or entity asserting the loss, liability, claim or 
damage at or prior to the time such furnishing is required by the Act and the 
Final Prospectus would have cured the defect giving rise to such loss, 
liability, claim or damage.

          5.10   The Licensor will severally, if the Common Stock held by the 
Licensor are included in the securities as to which such registration, 
qualification or compliance is being effected, indemnify the Company, each of 
its directors and officers, each underwriter and each person who controls the 
Company within the meaning of Section 15 of the Securities Act, against all 
claims, losses, damages and liabilities (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 or offering circular, or any amendment or supplement 
thereof, 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 not 
misleading, in light of the circumstances in which they were made, and will 
reimburse the Company, such directors and officers, each underwriter and each 
person controlling the Company for 

                                       13
<PAGE>

reasonable legal and any other expenses reasonably incurred in connection 
with investigating or defending any such claim, loss, damage, liability or 
action as incurred, in each case to the extent, but only to the extent, that 
such untrue statement or omission or allegation thereof is made in reliance 
upon and in conformity with written information furnished to the Company by 
or on behalf of the Licensor and stated to be specifically for use in 
preparation of such registration statement, prospectus or offering circular; 
provided that the indemnity shall not apply to the extent that such claim, 
loss, damage or liability results from the fact that a current copy of the 
prospectus was not made available to the Licensor and such current copy of 
the prospectus would have cured the defect giving rise to such loss, claim, 
damage or liability.


                           ARTICLE 6 - REPORTS AND RECORDS

          6.1    The Company shall keep full, true and accurate books of 
account containing all particulars that may be necessary for the purpose of 
showing the amounts payable to the Licensor by way of royalty as aforesaid. 
After First Commercial Sale, the Licensor may conduct an audit of the books 
of account of the Company by the Licensor's internal audit division and/or by 
another designated auditor selected by the Licensor, except one to whom the 
Company has reasonable and material objection at the sole cost of the 
Licensor at least once per year upon reasonable notice to the Company and at 
a mutually agreeable time.  In the event that an inspection shows an under 
reporting or underpayment in excess of the greater of (a) fifty thousand 
dollars ($50,000) and (b) five percent (5%) of royalties payable for any 
twelve (12) month period, then the Company shall reimburse the Licensor for 
the cost of the inspection at the time the Company pays the unreported 
royalties.  In addition, the Company shall conduct an independent audit of 
sales and royalties at least every three (3) years if annual sales of 
Licensed Products or Licensed Processes exceeds ten million dollars 
($10,000,000).  The audit shall address, at a minimum, the amount of gross 
sales by or on behalf of the Company during the audit period, the amount of 
funds owed to the Licensor under this Agreement and whether the amount owed 
has been paid to the Licensor and is reflected in the records of the Company. 
 A report by the auditor shall be submitted to the Licensor promptly upon 
completion.  The cost of such audit shall be borne by the Company.

          6.2    Within sixty (60) days from the end of each quarter of each 
calendar year, the Company shall deliver to the Licensor complete and 
accurate reports, giving such particulars of the business conducted by the 
Company during the preceding quarter under this License Agreement as shall be 
pertinent to a royalty accounting hereunder.  These shall include at least 
the following:

                 6.2.1   All Licensed Products and Licensed Processes used, 
leased or sold, by or for the Company or its Affiliates.

Licensed Processes used, leased or sold, by or for the Company or its 
Affiliates.

                 6.2.3   Deductions applicable in computed "Net Sales" as 
defined in Paragraph 1.7.

                 6.2.4   Total royalties due based on Net Sales by or for the 
Company or its Affiliates.

                                       14

                 6.2.5   Names and addresses of all sublicensees and 
Affiliates of the Company.

                 6.2.6   On an annual basis, the Company's year-end financial 
statements.

          6.3    With each such quarterly report submitted, the Company shall 
pay to the Licensor the royalties due and payable under this Agreement.  If 
no royalties shall be due, the Company shall not be required to make a report 
pursuant to this Article 6.

          6.4    Amounts which are not paid when due and which are not the 
subject of a bona fide dispute shall accrue interest from the due date until 
paid, at a rate equal to then prevailing prime rate of Citibank, N.A., plus 
two percent (2%).

          6.5    The Company agrees to forward to the Licensor annually a 
copy of any report, which is in substance similar to the report required by 
this Article 6, received from any sublicensee and other documents received

pertinent to an accounting of royalties.

foregoing, the Licensor may disclose any such information required to be

subpoena, requirement or order, provided that the Licensor takes reasonable 
steps to provide the Company with the opportunity to contest such request, 
subpoena, requirement or order.

                    ARTICLE 7 - PATENT PROSECUTION AND MAINTENANCE

          7.1    Upon receipt of appropriate documentation of expenses, the 
Company shall pay to the Licensor the approximate amount of Two Hundred 
Thousand dollars ($200,000), payable over a six (6) month period upon the 
earlier to occur of (a) receipt by the Company of the N.C.I. Clinical Data 
and pre-clinical data or (b) the date that is six (6) months from the 
Effective Date, for all reasonable out-of-pocket expenses that the Licensor 
has incurred in connection with the preparation, filing, prosecution and 
maintenance of the Patent Rights prior to the execution of this Agreement.  
Subject to the provisions of Article 7.3 hereof, the Company shall continue 
to reimburse the Licensor for all such future reasonable out-of-pocket 
expenses within sixty (60) days from receipt by the Company of appropriate 
documentation of such expenses by the Licensor.

          7.2    The Licensor shall diligently prosecute and maintain the 
Patent Rights as set forth in Appendix I hereto (as the same may be amended 
or supplemented from time to time after the date hereof), including, but not 
limited to, the filing of patent applications which may be required or 
desirable pursuant to and/or arising out of Sponsored Research, utilizing 
Pennie & Edmond as patent counsel or such other patent counsel in the future 
which may be mutually agreed upon by the parties hereto.  The Licensor agrees 
to keep the Company well informed with respect to the status and progress of 
any such applications, prosecutions and maintenance activities and to consult 
in good faith with the Company and take into account the Company's comments 
and requests with respect thereto.  Both parties agree to provide reasonable 
cooperation to each other to facilitate the application and prosecution of 
patents pursuant to this Agreement or arising out of any Sponsored Research.

          7.3    The Licensor may, in its discretion, elect to abandon any 
patent applications or issued patent comprising the Patent Rights, in which 
case the Company shall have no further royalty obligation to the Licensor in 
respect of any Licensed Products and Licensed Processes the manufacture, use 
or sale of which are covered by an issued claim of such abandoned Patent 
Rights.  Prior to any such abandonment, the Licensor shall give the Company 
at least sixty (60) days notice and a reasonable opportunity to take over 
prosecution of such Patent Rights.  In such event, the Company shall have the 
right, but not the obligation, to commence or continue such prosecution and 
to maintain any such Patent Rights under its own control and at its expense 
and the Company shall then have no royalty or other obligation to the 
Licensor in respect of any Licensed Products and Licensed Processes, the 
manufacture, use or sale of which is covered by an issued claim of such 
Patent Rights.  The Licensor agrees to cooperate in such activities including 
execution of any assignments or other documents necessary to enable the 
Company to obtain and retain sole ownership and control of such Patent Rights.

                               ARTICLE 8 - TERMINATION

          8.1    If the Company shall become bankrupt, or shall file a 
petition in bankruptcy, or if the business of the Company shall be placed in 
the hands of a receiver, assignee or trustee for the benefit of creditors, 
whether by the voluntary act of the Company or otherwise, this License 
Agreement shall automatically terminate.

          8.2    Should the Company fail to make payment to the Licensor of 
royalties due in accordance with the terms of this Agreement which are not 
the subject of a bona fide dispute between the Licensor and the Company, the 
Licensor shall have the right to terminate this License Agreement within 
sixty (60) days after giving said notice of termination unless the Company 
shall pay to the Licensor, within the 60-day period, all such royalties due 
and payable. Subject to Article 9, upon the expiration of the 60-day period, 
if the Company shall not have paid all such royalties due and payable, the 
rights, privileges and license granted hereunder shall, at the option of the 
Licensor, immediately terminate.

          8.3    Upon any material breach or default of this License 
Agreement by the Company, other than as set forth in Paragraphs 8.1 and 8.2 
hereinabove, the Licensor shall have the right to terminate this Agreement 
and the rights, privileges and license granted hereunder upon giving sixty 
(60) days notice to the Company.  Such grounds for termination include, but 
shall not be limited to, the Licensor's reasonable determination that the 
Company is not using its reasonable best efforts to keep Licensed Products or 
Licensed Processes reasonably available to the public after commercial use 
commences. Subject to Article 9, such termination shall become effective 
immediately unless the Company shall have cured any such breach or default 
prior to the expiration of the sixty (60) day period referred to above.

          8.4    The Company shall have the right at any time to terminate 
this Agreement in whole or as to any portion of the Patent Rights by giving 
ninety (90) days notice thereof in writing to the Licensor.

          8.5    Upon termination of this Agreement for any reason, nothing 
herein shall be construed to release either party from any obligation that 
matured prior to the effective date of such termination or obligations under 
Articles 6, 9, 10, 11, 16 and 17.  Notwithstanding the foregoing, if this 
Agreement is terminated by the Company prior to the date that is six (6) 
months from the date hereof, the Company shall have no obligation to make any 
payment under this Agreement whatsoever, except that the Company shall be 
required to pay fifty percent (50%) of the license fee set forth in section 
4.8.1.  The Company and/or any sublicensee thereof may, however, after the 
effective date of such termination and continuing for a period not to exceed 
six (6) months thereafter, sell all completed Licensed Products, as well as 
any Licensed Products in the process of manufacture at the time of such 
termination, provided that the Company shall pay or cause to be paid to the 
Licensor the royalties thereon as required by Article 4 of this License 
Agreement and shall submit the reports required by Article 6 hereof on the 
sales of Licensed Products.

          8.6    If not terminated sooner, this Agreement shall terminate on 
the date of the last to expire claim contained in the Patent Rights.

<PAGE>

          8.7    Paragraph 4.11 shall survive termination of this Agreement 
for a period of two (2) years from the date of termination unless this 
Agreement is terminated as a result of a breach by any of the Co-owners or 
failure of the Licensed Products to prove efficacious.


                               ARTICLE 9 - ARBITRATION

          9.1    Any dispute or any controversy between the parties involving 
the construction or application of any terms, covenants or conditions of this 
Agreement, or transactions under it or any claim arising out of or relating 
to this Agreement, shall be submitted to binding arbitration.  The parties 
shall first use good faith efforts to resolve any such dispute through full 
and meaningful discussions, which shall include at least one face-to-face 
meeting between authorized representatives of each party and a written 
exchange of positions.  If, after ninety (90) days from the date of first 
discussion of the disputed issues, the parties are unable to resolve the 
dispute, either party may refer the dispute, controversy or claim to 
arbitration in New York, New York in accordance with the provisions set forth 
below and the Commercial Arbitration Rules of the American Arbitration 
Association (the "AAA") then in effect. Judgement upon the award rendered by 
the arbitrators may be entered in any court having jurisdiction thereof.  
Notwithstanding anything to the contrary which may now or hereafter be 
contained in said rules of the AAA, the parties hereby agree as follows:

          9.1.1  Each party shall appoint one (1) person to hear and 
determine the dispute on or before the end of the sixtieth (60th) day after 
receipt of notice of arbitration from the noticing party, and who shall have 
reviewed and agreed to terms of this clause.  Within thirty (30) days 
therefrom, the two persons so chosen shall select a third, impartial 
arbitrator and the majority decision of the tribunal shall be final and 
conclusive upon both parties.  All such arbitrators shall be experienced in 
the field related to the Agreement.  If either party fails to designate its 
arbitrator within the time period set forth above, then the arbitrator 
designated by the one party shall act as the sole arbitrator and shall be 
deemed to be the single, mutually approved  arbitrator to resolve the 
controversy.  If the two selected arbitrators fail to agree upon the identity 
of a third, said third arbitrator shall be selected by the AAA upon 
application of either party thereto.  If the parties are unable to agree upon 
a rate of compensation for the arbitrators, they shall be compensated for 
their services at a rate to be determined by the AAA.

          9.1.2  Discovery shall be governed by the Federal Rules of Civil 
Procedure.  The scope and extent thereof shall be as the arbitrators 
determine to be appropriate under the circumstances.  The arbitrators shall 
issue a ruling within thirty (30) days of impanelment setting forth the scope 
and extent of discovery, and the date when all discovery is to be concluded.  
Although the arbitrators shall have the duty to meet with the parties at 
least once in order to hear evidence, the panel shall avail itself of all 
available technologies, including conference calling and video conferencing, 
to resolve pre-hearing and/or discovery matters.

          9.1.3  The arbitrators shall have the power and authority to award 
relief under legal or equitable principles, including interim or preliminary 
relief.

          9.1.4  The costs of the arbitration (excluding attorney's fees) 
shall be borne by the  non-prevailing party.

                                       18
<PAGE>

          9.1.5  The arbitrators shall have the right to direct the payment 
of attorney's fees in their sole discretion.

     9.2  Within one-hundred-eighty (180) days of the date of impanelment 
(the date on which the third arbitrator agrees to serve, or the date on which 
one of the parties fails to designate an arbitrator), the arbitrators shall, 
upon the request of either party, issue a draft of a factual detailed, 
reasoned written opinion of their findings of fact and conclusions of law.  
Upon receipt by the requesting party of said written opinion, said requesting 
party shall have the right within twenty (20) days to file a Motion to 
Reconsider, and the arbitrators thereupon shall reconsider the issues raised 
by said motion and either confirm or modify their decision.  In any event, 
the arbitrators shall then issue a Final Decision which shall then be final 
and conclusive upon bot parties hereto.


                     ARTICLE 10 - INFRINGEMENT AND OTHER ACTIONS

          10.1   The Company and the Licensor shall promptly provide written 
notice, to the other party, of any alleged infringement by a third party of 
the Patent Rights and provide such other party with any available evidence of 
such infringement.

          10.2   During the term of this Agreement, the Company shall have 
the right, but not the obligation, to prosecute and/or defend, at its own 
expense and utilizing counsel of its choice, any infringement of, and/or 
challenge to, the Patent Rights.  In furtherance of such right, the Licensor 
hereby agrees that the Company may join the Licensor as a party in any such 
suit, without expense to the Licensor.  No settlement, consent judgment or 
other voluntary final disposition of any such suit which would adversely 
affect the rights of the Licensor may be entered into without the consent of 
the Licensor, which consent shall not be unreasonably withheld.  The Company 
shall indemnify and hold the Licensor harmless against any costs, expenses or 
liability that may be found or assessed against the Licensor in any such suit 
other than resulting from the Licensor's negligence or wilful misconduct.

          10.3   In the event that a claim or suit is asserted or brought 
against the Company alleging that the manufacture or sale of any Licensed 
Product by the Company, an Affiliate of the Company, or any sublicensee, or 
the use of such Licensed Product by any customer of any of the foregoing, 
infringes proprietary rights of a third party, the Company shall give written 
notice thereof to the Licensor.  The Company may, in its sole discretion, 
modify such Licensed Product to avoid such infringement and/or may settle on 
terms that it deems advisable in its sole discretion, subject to paragraph 
10.2.  Otherwise, the Company shall have the right, but not the obligation, 
to defend any such claim or suit.  In the event the Company elects not to 
defend such suit, the Licensor shall have the right, but not the obligation 
to do so at its sole expense.

          10.4   Any recovery of damages by the Company, in any such suit, 
shall be applied first in satisfaction of any unreimbursed expenses and legal 
fees of the Company relating to the suit and then to the Licensor for any 
royalties credited in accordance with paragraph 10.5.  The balance remaining 
from any such recovery shall be treated as royalties received by the Company 
from sublicensees and shared by the Licensor and the Company in accordance 
with Paragraph 4.1.2 hereof.

                                       19
<PAGE>

          10.5   The Company may credit up to fifty percent (50%) of any 
litigation costs incurred by the Company in any country pursuant to this 
Article 10 and up to 50% of all amounts paid in judgement or settlement of 
litigation pursuant to this Article 10 against royalties thereafter payable 
to the Licensor hereunder for such country and apply the same toward one-half 
of its actual, reasonable out-of-pocket litigation costs.  If one-half of 
such litigation costs in such country exceeds 50% of royalties payable to the 
Licensor in any year in which such costs are incurred than the amount of such 
costs, expenses and amounts paid in judgement or settlement, in excess of 
such 50% of the royalties payable shall be carried over and credited against 
royalty payments in future years for such country.

          10.6   If within six (6) months after receiving notice of any 
alleged infringement, the Company shall have been unsuccessful in persuading 
the alleged infringer to desist, or shall not have brought and shall not be 
diligently prosecuting an infringement action, or if the Company shall notify 
the Licensor, at any time prior thereto, of its intention not to bring suit 
against the alleged infringer, then, and in those events only, the Licensor 
shall have the right, but not the obligation, to prosecute, at its own 
expense and utilizing counsel of its choice, any infringement of the Patent 
Rights, and the Licensor may, for such purposes, join the Company as a party 
plaintiff.  The total cost of any such infringement action commenced solely 
by the Licensor shall be borne by the Licensor and the Licensor shall keep 
any recovery or damages for infringement or otherwise derived therefrom and 
such shall not be applicable to any royalty obligation of the Company.

          10.7   In any suit to enforce and/or defend the Patent Rights 
pursuant to this License Agreement, the party not in control of such suit 
shall, at the request and expense of the controlling party, cooperate in all 
respects and, to the extent possible, have its employees testify when 
requested and make available relevant records, papers, information, samples, 
specimens, and the like.


                   ARTICLE 11 - LIMITATION OF LIABILITY, INDEMNITY

          11.1   The Licensor, by this License Agreement, makes no 
representations or warranties as to the validity and/or breadth of the 
inventions contained in the Patent Rights and the Company so acknowledges.  
The Licensor, by this License Agreement makes no representations or 
warranties as to patents now held or which will be held by others in the 
field of the Licensed Products  and/or Licensed Processes for a particular 
purpose.

          11.2   EXCEPT AS MAY BE EXPRESSLY PROVIDED HEREIN, THE LICENSOR 
DOES NOT MAKE, AND EXPRESSLY DISCLAIMS ANY WARRANTIES, EITHER EXPRESS OR 
IMPLIED, ORAL OR WRITTEN, AS TO ANY MATTER WHATSOEVER, INCLUDING 
MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.

          11.3   The Company agrees to defend, indemnify and hold the 
Licensor harmless from and against all liability, demands, damages, including 
without limitation, expenses or losses including death, personal injury, 
illness or property damage arising directly or indirectly (a) out of use by 
the Company or its transferees of inventions licensed or information 
furnished under this License Agreement or (b) out of any use, sale or other 
disposition by the Company or its transferees of Patent Rights, Licensed 
Products or Licensed Processes, in each case which are not judicially 
determined to be the result of Licensor's negligence or wilful misconduct.  
The Company agrees that any sublicense agreement it enters relative to the 
Licensed Products and/or Licensed Processes shall contain a covenant by such 
sub-licensee providing for the indemnification of the Licensor as provided in 
this Article.

          11.4   Prior to the First Commercial Sale, the Company shall obtain 
and maintain products liability insurance covering the risk of claim, 
liabilities, expenses and judgments for which it has agreed to indemnify the 
Licensor pursuant to paragraph 11.3 hereof.  Coverage shall be in an amount 
which is not less than one million dollars ($1,000,000) per occurrence.  The 
parties agree that adequate evidence of the required coverage has or will be 
provided by the Company to the Licensor at: Penn State Intellectual Property 
Office, 113 Technology Center, University Park, PA 16802-7000, and the 
Company agrees to keep said office informed of any changes in coverage or 
carriers.


                               ARTICLE 12 - ASSIGNMENT

          This Agreement and the rights and duties appertaining hereto may 
not be assigned by either party without first obtaining (a) the written 
consent of the other, which consent shall not be unreasonably withheld and 
(b) the approval of the N.I.H., which shall not be unreasonably withheld.  
Any such purported assignment, without the written consent of the other party 
and the N.I.H., shall be null and of no effect.  Notwithstanding the 
foregoing, the Company may assign this Agreement without the consent of the 
Licensor (i) to a purchaser, merging or consolidating corporation, or 
acquirer of substantially all of the Company's assets or business and/or 
pursuant to any reorganization qualifying under section 368 of the Internal 
Revenue Code of 1986 as amended, as may be in effect at such time in an 
arm's-length transaction approved by the Board of Directors in accordance 
with applicable law, provided that the surviving entity of such purchase, 
merger, consolidation, acquisition or reorganization is a publicly traded 
company and agrees to abide by the terms of this Agreement, or (ii) to an 
Affiliate of the Company, provided that such Affiliate is a publicly traded 
company and/or the Company agrees to continue to satisfy all payment 
obligations owed to the Licensor hereunder.

<PAGE>

                      ARTICLE 13 - PAYMENT OF FEES AND EXPENSES

          Each of the Company and the Licensor shall be responsible for their 
own expenses relating to the preparation and consummation of this Agreement 
and the agreements and transactions contemplated hereby.


                      ARTICLE 14 - USE OF NAMES AND PUBLICATION

          14.1   Nothing contained in this Agreement shall be construed as 
granting any right to the Company or its Affiliates to use in advertising, 
publicity, or other promotional activities any name, trade name, trademark, 
or other designation of the Licensor or any of its units (including 
contraction, abbreviation or simulation of any of the foregoing) without the 
prior, written consent of the Licensor; provided, however, that the Licensor 
acknowledges and agrees that the Company may use the name of the Licensor and 
the names of the Principal Investigators in various documents used by the 
Company for capital raising and financing without such prior written consent 
but only to the extent that such use of names may be reasonably required by 
law.  The Licensor acknowledges that the Principal Investigators may act as 
consultants and scientific advisors to the Company with respect to the 
licenses granted to the Company hereunder, subject to the respective policies 
of the Licensor.

          14.2   Nothing herein shall be deemed to establish a relationship 
of principal and agent between the Licensor and the Company, nor any of their 
agents or employees for any purpose whatsoever.  This Agreement shall not be 
construed as creating a partnership between the Licensor and the Company, or 
as creating any other form of legal association or arrangement which would 
impose liability upon one party for the act or failure to act of the other 
party.

          14.3   Except as set forth in paragraph 14.4, in the event that the 
Licensor or Principal Investigators desire, individually or as a group, to 
publish or disclose, by written, oral or other presentation, Know-how, Patent 
Rights, or any material information related thereto then the Licensor or the 
Principal Investigator(s) shall notify the Company in writing by facsimile 
where confirmed by the receiving party, and/or by certified or registered 
mail (return receipt requested) of their intention at least sixty (60) days 
prior to any speech, lecture or other oral presentation and at least sixty 
(60) days before any written or other publication or disclosure.  The 
Principal Investigator(s) shall include with such notice a description of any 
proposed oral presentation or, in any proposed written or other disclosure, a 
current draft of such proposed disclosure or abstract.  No later than thirty 
(30) days following the receipt of such notice, the Company may request that 
the Principal Investigator(s) and the Licensor, delay such presentation, 
publication or disclosure for a reasonable period of time in order to enable 
the Company to file, or have filed on their behalf, a patent application, 
copyright or other appropriate form of intellectual property protection 
related to the information to be disclosed or request that the Licensor do 
so.  Upon receipt of such request to delay such presentation, publication or 
disclosure, the Licensor and the Principal Investigator(s) shall arrange for 
a delay of such presentation, publication or disclosure for a reasonable 
period of time necessary for the Company or the Licensor to file, or have 
filed on its behalf, such patent application,

                                       22
<PAGE>

copyright or other appropriate form of intellectual property protection in 
form and in substance reasonably satisfactory to the Company and the 
Licensor; provided, however, that in no event shall such delay be greater 
than forty-five (45) days.  If neither the Principal Investigator(s) nor the 
Licensor receive any such request from the Company to delay such 
presentation, publication or disclosure, the Licensor or the Principal 
Investigator(s) may submit such material for presentation, publication or 
other form of disclosure.

          14.4   In the event that the N.I.H., or the Principal 
Investigator(s) of the N.I.H. (the "N.I.H. Investigator(s)"), desires, 
individually or as a group, to publish or disclose, by written, oral or other 
presentation, Know-how, Patent Rights, or any material information related 
thereto then the N.I.H. or the N.I.H. Investigator(s) shall notify the 
Company in writing by facsimile where confirmed by the receiving party, 
and/or by certified or registered mail (return receipt requested) of their 
intention at least thirty (30) days prior to any speech, lecture or other 
oral presentation and at least thirty (30) days before any written or other 
publication or disclosure.  The N.I.H. Investigator(s) shall include with 
such notice a description of any proposed oral presentation or, in any 
proposed written or other disclosure, a current draft of such proposed 
disclosure or abstract.  No later than thirty (30) days following the receipt 
of such notice, the Company may request that the N.I.H. and the N.I.H. 
Investigator(s), delay such presentation, publication or disclosure for an 
additional period of thirty (30) days (which 30-day period shall not be 
renewable) in order to enable the Company to file, or have filed on their 
behalf, a patent application, copyright or other appropriate form of 
intellectual property protection related to the information to be disclosed 
or request that the N.I.H. do so.  Upon receipt of such request to delay such 
presentation, publication or disclosure, the N.I.H. and the N.I.H. 
Investigator(s) shall arrange for a second thirty (30) day period of delay of 
such presentation, publication or disclosure so that the Company or the 
N.I.H. may file, or have filed on its behalf, such patent application, 
copyright or other appropriate form of intellectual property protection in 
form and in substance reasonably satisfactory to the Company and the N.I.H.  
If neither the N.I.H. nor the N.I.H. Investigator(s) receive any such request 
from the Company to delay such presentation, publication or disclosure, the 
N.I.H. or the N.I.H. Investigator(s) may submit such material for

          16.1   Any proprietary or confidential information directly 
relating to the Invention  (including but not limited to Know-how and patent 
prosecution documents relating to Patent Rights) collectively constitute the 
"Confidential Information."  The Company and the Licensor agree that they 
will not use the Confidential Information for any purpose unrelated to this 
Agreement or any Sponsored Research, and will hold it in confidence during 
the term of this Agreement and for a period of five (5) years after the 
termination or expiration date of this Agreement.  The Company shall exercise 
with respect to such the Confidential Information the same degree of care as 
the Company exercises with respect to its own confidential or proprietary 
information of a similar nature, and shall not disclose it or permit its 
disclosure to any third party (except to those of its employees, consultants, 
or agents who are bound by the same obligation of confidentiality as the 
Company is bound by pursuant to this Agreement).  However, such undertaking 
of confidentiality by the Company shall not apply to any information or data 
which:

                 16.1.1  The Company receives at any time from a third-party 
lawfully in possession of same and having the right to disclose same.

                 16.1.2  Is, as of the date of this Agreement, in the public 
domain, or subsequently enters the public domain through no fault of the 
Company.

                 16.1.3  Is independently developed by the Company as 
demonstrated by written evidence without reference to information disclosed 
to the Company by the Licensor.

                 16.1.4  Is disclosed pursuant to the prior written approval 
of the Licensor.

                 16.1.5  Is required to be disclosed pursuant to law or legal 
process (including, without limitation, to a governmental authority) 
provided, in the case of disclosure pursuant to legal process, reasonable 
notice of the impending disclosure is provided to the Licensor and the 
Licensor has agreed to such disclosure in writing or have exhausted their 
right to contest such disclosure.


                        ARTICLE 17 - MISCELLANEOUS PROVISIONS    

          17.1   This License Agreement shall be construed, governed,

change of modification except by the execution of a written instrument 
subscribed to by the parties hereto.

          17.5   The provisions of this License Agreement are severable, and 
in the event that any provision of this License Agreement shall be determined 
to be invalid or unenforceable under any controlling body of law, such 
invalidity or unenforceability shall not in any way affect the validity or 
enforceability of the remaining provisions hereof.

          17.6   The failure of either party to assert a right hereunder or 
to insist upon compliance with any term or condition of this License 
Agreement shall not constitute a waiver of that right or excuse a similar 
subsequent failure to perform any such term or condition by the other party.

          17.7   The headings of the several articles are inserted for 
convenience of reference only and are not intended to be a part of or to

                                     EXHIBIT A
                 DRAFT PLAN FOR THE DEVELOPMENT OF O6-BENZYL GUANINE
                               AND RELATED TECHNOLOGIES

     The following will serve to outline Pacific Pharmaceuticals, Inc.'s (the 
"Company") plans for development of O6-Benzyl guanine ("BG") and related 
technologies as an intervenous chemotherapeutic agent used in combination 
with alkylating agents such as BCNU (the "Agent" or "Agents") for the 
treatment of cancer.

     The Company intends to establish a clinical development plan in order to 
obtain regulatory approval of BG from the United States Food and Drug 
Administration as well as from equivalent foreign regulatory authorities on a 
world-wide basis.  It is anticipated that with the information currently 
available from completed pre-clinical and clinical studies conducted by the 
National Institute of Health, the Cancer Therapy Evaluation Program ("CTEP"), 
the National Cancer Institute and various universities, the Company will be 
able to commence Phase II clinical trials.

     The Company believes that the continued participation of CTEP will be 
ensured through the execution of a Cooperative Research and Development 
Agreement ("CRADA") to be negotiated by and between the Company and CTEP.  
The Phase II study may involve therapy with a combination of BG and an Agent 
in previously untreated cancer patients or in patients who have failed 
therapy with an Agent.

     The Company will study the benefits of development of selected related 
technologies through Sponsored Research Agreements or other means.  Related 
technologies of potential interest to the Company may include 8-oxo-BG, 
certain ribosylated derivatives with increased water solubility, and gene 
therapy approaches to protecting the bone marrow from toxicity.

     The Company and /or its Affiliates agree to use their reasonable best 
efforts to attain the following milestones for its performance under this 
agreement and, within sixty (60) days of achieving a milestone, shall notify 
the Co-owners that such milestone has been achieved.

     For the O6 Benzylguanine parent molecule:

It is understood and agreed by the Co-owners that in the event that the 
Company is not provided with the N.C.I. Clinical Data and pre-clinical data, 
then each of the above milestones shall be extended by three (3) years.

     For additional candidate compounds, if any, the Company and/or its 
Affiliates agree to use reasonable best efforts to proceed with pre-clinical 
development within four (4) years.  If after that time, the Company and/or 
its Affiliates have not commenced pre-clinical development, the Company 
and/or its Affiliates will give due consideration to granting a sublicense to 
companies interested in developing any such additional candidate compounds.

                               INTRODUCTION AGREEMENT

     Pursuant to this Introduction Agreement (this "Agreement") entered into 
as of February 12, 1998 (the "Effective Date"), between Paramount Capital 
Investments, LLC, having a place of business at 787 Seventh Avenue, 48th 
floor, New York, New York 10019 (the "Disclosing Party") and Pacific 
Pharmaceuticals, Inc. (the "Recipient"), the parties hereto agree: 

          1.   The Disclosing Party will introduce Recipient to the persons, 
universities and/or companies (each an "Introduced Party") listed on Schedule 
I with the intent that Recipient may acquire the technologies and companies 
described thereon being developed by such parties (the "Acquisition 
Candidates").

          2.   In the event that the Recipient enters into a contract, 
license, stock purchase agreement, loan agreement or any other agreement or 
arrangement with respect to any of the Acquisition Candidates, then the 
Recipient shall pay to the Disclosing Party for each such Acquisition 
Candidate a $100,000 cash fee, of which payment of $50,000 is due upon 
signing of an agreement for an Acquisition Candidate and $50,000 shall be 
deferred until Recipient has raised $1,000,000 in a financing. Additionally, 
Recipient shall grant to the Disclosing Party and/or its designees a number 
of shares of common stock of the Company, par value $.002 per share, vesting 
according to Schedule II attached hereto.  In addition, upon receipt of 
appropriate documentation, the Recipient shall reimburse the Disclosing Party 
for all reasonable expenses incurred in connection with any Acquisition 
Candidate not to exceed $100,000.  For a period of thirty-six (36) months 
from the date hereof, Recipient shall not enter into a contract, license, 
stock purchase agreement, loan agreement or other agreement or arrangement 
with any Introduced Party unless the compensation as set forth herein is paid 
to the Disclosing Party. 

          3.   It is agreed that the compensation to Disclosing Party with 
respect to the Acquisition Candidates shall be solely the obligation of 
Recipient.

          4.   Recipient recognizes and understands that the Disclosing Party 
has not executed any agreements (other than the Confidentiality Agreement as 
described below and attached hereto as Exhibit A) with respect to the 
proposed Acquisition Candidates and therefore Recipient agrees not to contact 
any such parties or any of their officers, directors, employees, agents, 
affiliates and/or consultants without an officer of the Disclosing Party or 
without the prior written consent of an officer of the Disclosing Party and 
further agrees not to take any action that would adversely affect or 
otherwise hinder the Disclosing Party's ability to ultimately execute any 
agreements with such parties. 

<PAGE>

          5.   This Agreement constitutes the entire agreement of the parties 
pertaining to the subject matter hereof, and the parties have made no 
agreements, representations or warranties relating to the subject matter of 
this Agreement that are not set forth herein and no agreement subsequent to 
the date hereof relating to the subject matter of this Agreement shall be 
binding upon either party unless in writing and executed by both the 
Disclosing Party and Recipient.  

          6.   Neither party shall be reasonable in relying on oral 
statements made by the other which are not contained in a written agreement 
signed by both parties  This Agreement may not be modified, amended or waived 
in any manner except by an instrument in writing signed by each of the 
parties hereto.  

          7.   The waiver by either party of compliance with any provision of 
this Agreement by the other party shall not operate or be construed as a 
waiver of such party of a provision of this Agreement.  

          8.   Neither party may assign its rights or obligations hereunder.  

          9.   This Agreement shall be governed by and construed in 
accordance with the laws of the State of New York, without regard to the 
conflicts of the law principles thereof.

          10.  Any disputes between the parties hereto arising out of this 
Agreement and the transactions contemplated hereby shall be determined by 
valid and binding arbitration in New York, New York.

          11.  This Agreement may be executed in any number of counterparts, 
each of which counterparts, when so executed and delivered, shall be deemed 
an original, and all of which counterparts, taken together, shall constitute 
one and the same instrument.

          12.  Any notice or other communication under this Agreement shall 
be in writing and shall be deemed to have been given: when delivered 
personally against receipt therefor; one (1) day after being sent by Federal 
Express or similar overnight delivery; or three (3) days after being mailed

FOR IMMEDIATE RELEASE

                 PACIFIC PHARMACEUTICALS LICENSES CHEMOSENSITIZER 
                                     FOR CANCER

   -RELATED COMPOUNDS AND TECHNOLOGIES TO OVERCOME CANCER DRUG RESISTANCE-

SAN DIEGO, CA, March 23, 1998 - Pacific Pharmaceuticals, Inc. today announced 
a worldwide exclusive license for O6 Benzyl Guanine (BG), a series of related 
compounds and technologies which enhance the effectiveness of a class of 
currently used chemotherapeutic agents (O6 alkylators).  Multiple Phase I 
human clinical trials conducted at the University of Chicago, Duke University 
Medical Center and Case Western Reserve University are nearing completion in 
different cancer types, including brain, colon and renal carcinoma.  These 
technologies are licensed to Pacific from Pennsylvania State University on 
behalf of itself, National Institutes of Health and other universities.

Pre-clinical animal data show that treatment with BG results in increased 
survival and heightens the anti-tumor activity of chemotherapeutic agents. 
The Company's collaborators believe that BG works by inactivating the DNA 
repair protein AGT (O6 alkylguanine-DNA alkyltransferase) present in tumor 
cells and known to be a significant source of resistance to treatment with 06 
alkylating agents.  Studies led by Pugh Scholar Dr. Anthony E. Pegg and his 
team have shown a correlation between low levels of the repair protein AGT in 
tumors and enhanced responsiveness to treatment.  

 "O6 Benzylguanine has the potential to enhance the activity of O6 alkylating 
agents in drug resistant cancers.  This is particularly exciting because 
cancer resistance to these alkylating agents has been a major problem for 
their efficacy," commented Dr. David Golde, Physician-in-Chief, Sloan 
Kettering Cancer Center and Chairman of Pacific's Scientific Advisory Board. 

"This novel class of compounds has the potential to expand the indications 
for O6 alkylating agents to other cancers," stated H. Laurence Shaw, M.D., 
Chairman, President and Chief Executive Officer.  Pacific Pharmaceuticals, 
Inc. is actively engaged in the development of cancer therapies, and is 
preparing to enter Phase I/II human clinical trials this year with its 
proprietary photodynamic therapy compound BOPP for the treatment of brain 
cancer, and a proprietary Cancer Immunotherapy for the treatment of 
metastatic breast cancer. The Company manages products through pre-clinical, 
clinical development and regulatory approval to position them for successful 
commercialization.
