                       NOTES TO FINANCIAL STATEMENTS
                       -----------------------------
                                (Unaudited)

A. BASIS OF PRESENTATION
   ---------------------
   The financial statements for the three and six month periods ended
December 31, 1999 and 1998 have been prepared without audit and, in the
opinion of management, all adjustments (which include only normal
recurring adjustments) necessary to fairly present the Company's
financial position, results of operations, and cash flows at December
31, 1999 and 1998 and for the periods then ended have been made.
Certain information and footnote disclosures normally included in
financial statements prepared in accordance with generally accepted
accounting principles have been omitted.  Certain amounts in prior year
financial statements have been reclassified to conform to current year
presentation.

   These financial statements should be read in conjunction with the
financial statements and notes thereto included in the Company's Annual
Report on Form 10-K for the fiscal year ended June 30, 1999.  The
results of operations for the periods ended December 31, 1999 and 1998
are not necessarily indicative of the operating results for the full
year.

   The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities
at the date of the financial statements and the reported amounts of
revenues and expenses during the reporting period.  Actual results could
differ from those estimates.

B. OTHER INCOME
   ------------
   Other income includes sales related royalties and $75,000 ($69,750 net
of commissions) per quarter under a three-year program funded by Aventis
Pasteur formally known as Pasteur Merieux Serums & Vaccins, S.A.
("PMS&V") a subsidiary of Rhone-Poulenc (now known as Aventis
Pharmaceuticals) to fund the Company's vaccine adjuvant development
program.

C. INCOME TAXES
   ------------
   Although tax benefits were recorded against the net losses incurred in
periods ending on or before June 30, 1999, such benefits are no longer
available for periods commencing thereafter.

D. ACCOUNTS RECEIVABLE
   -------------------
   Accounts receivable - other consists of an amount due in November 2000
pursuant to a litigation settlement agreement entered into in 1996. This
amount has been discounted to reflect its present value.  The Company
has licensed manufacture and sale of its products to another company and
discontinued all manufacturing and sales activities in October 1999.
All of the Company's trade receivables have been collected.

E. CHANGES IN SHAREHOLDERS' EQUITY
   -------------------------------
   During the six-month period ended December 31, 1998, shareholders'
equity increased $677,378 due to the sale of 1,333,333 shares of common
stock to Pasteur Merieux Serums & Vaccins, S.A. ("PMS&V") for $1
million, less $70,000 due to BlueStone on the transaction offset, in
part, by a net loss of $252,621.  In July 1999, shareholders' equity
decreased due to the repurchase, for $1,263,700, of 5,558,406 shares of
the Company's Common Stock for Treasury.  In November 1999, 150,000
shares of the Company's Common Stock were issued pursuant to the
exercise of an option by a former director of the Company, increasing
shareholders' equity by $9,555.  During the three and six month periods
ended December 31, 1999, shareholders' equity was decreased by net
losses of $186,154 and $577,441, respectively, and the effect of the
aforementioned transactions.

Item 2.  Management's Discussion and Analysis of Results of
	  Operations and Financial Condition
         --------------------------------------------------

   The following discussion should be read in conjunction with and is
qualified in its entirety by the accompanying financial information and
notes thereto, and management's discussion and analysis of results of
operations and financial condition contained in the Company's Annual Report
on Form 10-K for the fiscal year ended June 30, 1999.

   Certain statements in this discussion and analysis constitute forward-
looking statements, are not historical facts, and involve risks and
uncertainties that could cause actual results to differ from those


<PAGE> 9

expected and projected.  Such risks and uncertainties include but are not
limited to: (i) general economic conditions; (ii) conditions specific to
the biotechnology industry; (iii) the Company's ability to develop or
acquire new technology or products through licensing, merger or acquisition
and to obtain regulatory approval to commercialize diagnostic or
therapeutic products; (iv) the effectiveness and ultimate market acceptance
of any such products; (v) limitations on third party reimbursements with
respect to any such products; and (vi) competition.  The Company does not
undertake to update or revise any forward-looking statements contained
herein whether as a result of new information, future events or otherwise.

Results of Operations
- ---------------------
   The Company has only sold its products to the research market and has not
generated any significant revenues therefrom.   The Company ceased the direct
sale of its products to the research market as of October 31, 1999.

   The Company believes it is a development stage enterprise because planned
principal operations have not yet commenced.  The Company's planned
principal operations include the development of clinical and therapeutic
products for distribution through pharmaceutical and diagnostic companies.
This requires the approval of the Company's products by the FDA.  At
December 31, 1999, none of the Company's products had received such
approval.  In addition, the Company continues to devote most of its efforts
to activities such as research and development, financial planning and
developing markets which are typical activities for a development stage
enterprise.

   Specifically, the Company has expended funds relating to its vaccine
adjuvant program.  From October 5, 1998 through December 15, 1999, the
Company engaged the services of Genome Securities, Inc. ("Genome"), whose
Chairman and CEO, Robert Naismith, Ph.D. is also a member of the Company's
Board of Directors, to act as Cistron's financial advisor as to corporate
strategic and financial initiatives.  Accordingly, as the Company has not yet
commenced principal operations and is devoting most of its efforts to
activities typical of a development stage enterprise as outlined in Statement
of Financial Accounting Standards No.7, the Company believes that it continues
to be in the development stage.

   The Company has outsourced all of its manufacturing and research and
development efforts. The Company reached an agreement with its landlord to
terminate the lease on its office and production space and has further
arranged with the new tenant temporarily to share office space in the
formerly leased facility where it can oversee its research and development
programs and pursue its strategic objectives. The lease change coincided
with an employee reduction in force and all but two of the Company's
employees have been terminated.

   The Company has held exploratory discussions with several biotechnology
and pharmaceutical companies regarding possible strategic alliances including
joint ventures, mergers or the sale of the Company.  There can be no
assurance that the Company will be successful in consummating a merger or
entering into a partnership agreement.  Without such event, the Company may
consider a partial or full liquidation of the Company, though no such
decision has been made at this time.  Management believes that it will have
sufficient assets to fund the Company's current programs and plans through
fiscal 2000 and beyond.

<PAGE> 10

Three Months Ended December 31, 1999 and Three Months Ended December 31, 1998
- -----------------------------------------------------------------------------

   Sales decreased $49,830 (97%) in the quarter ended December 31, 1999 versus
the same period of the prior year due to the Company's earlier decision to
withdraw from direct production and sale of its IL-1 assays. Only
accommodation sales of remaining available products occurred in this
quarter.

   Operating expenses increased $105,380 (30%) in the quarter ended December
31, 1999 versus the same quarter of the prior year reflecting significantly
higher administrative and R&D expenses offset by reduced occupancy expense.
Research and development expenses increased $33,320 (64%) due primarily to
the timing of payments for external research funding for vaccine adjuvant
studies.  Administrative expenses increased $99,687 (40%) due primarily to
the increase in patent related legal expenses of $34,151, and to
higher consultant and audit expenses offset by reduced employee salary
expense as a result of the staff reduction in October 1999.  Occupancy
expense decreased $27,709(57%) due to the termination of the Company's
facility lease and the transition to use of a small part of the facility.

   Interest income of $96,707, an increase of $25,483, was earned on the
investment of cash balances which were higher than in the same period of
the prior year.  In addition, net interest expense of $21,553 was
recognized on accounts receivable-other and other non-current liabilities
to reflect the increase in their present value and a revised estimate of
the liabilities.

   The Company had an operating loss of $391,387 in the quarter and there
can be no assurance that its operations will reach profitability.

   Cash was increased in the quarter by the collection of a receivable from
Immunex in the amount of $3 million ($2,167,500 net to the Company).


Six Months Ended December 31, 1999 and Six Months Ended December 31, 1998
- -------------------------------------------------------------------------

   Sales decreased $152,090 (74%) in the six months ended December 31, 1999
as compared to the same period of the prior year due to the Company's
decision to withdraw from direct production and sale of its products.

   Operating expenses increased $109,427(15%) in the six-month period ended
December 31, 1999 versus the same period of the prior year due primarily to
higher administrative expenses offset by lower occupancy expenses.

   Administrative expenses increased $123,647(26%) due mainly to higher legal
and consulting expenses offset, in part, by decreases in employee salaries
and benefits.  Legal expense increased $62,936 (84%) over the same period
of the prior year.  This change included an increase of $34,151 in patent
related legal expenses.  Occupancy expenses decreased $18,264(18%) due to
the termination of the Company's facility lease and the transition to use
of a small part of the facility.

   Interest income of $180,736, an increase of $41,436, was earned on the
investment of cash balances, which were higher than in the same period of
the prior year.  In addition, net interest expense of $20,052 was
recognized on accounts receivable-other and other non-current liabilities
to reflect the increase in their present value and a revised estimate of
the liabilities.  $739 in interest was collected on a tax receivable.

<PAGE> 11

   The Company had an operating loss of $577,541 in the six-month period
ended December 31, 1999 and there can be no assurance that its operations
will reach profitability.

   Cash was increased in the six month period by the collection in November
1999 of a receivable from Immunex in the amount of $3 million ($2,167,500
net to the Company).

Liquidity and Capital Resources
- -------------------------------

   At December 31, 1999, the Company had current assets of $10,124,501
including cash and cash equivalents of $9,064,524 and had current
liabilities of $401,737.  Cash was increased in the quarter ended December
31, 1999, by the collection of a payment of $3 million ($2,167,500 after
payments to counsel and certain health and research institutions) from
Immunex pursuant to settlement of patent litigation in November 1996.
A final payment of $1 million ($640,000 net to the Company) is due in
November 2000.  Cash used in the six-month period ended December 31, 1999
was largely for operating expenses.

   From October 1998 through December 15, 1999, Cistron engaged Genome
Securities, Inc., whose Chairman and CEO, Robert Naismith, Ph. D. is also a
member of the Company's Board of Directors, to act as Cistron's financial
advisor as to corporate strategic and financial initiatives.  In this
regard, the Company has held exploratory discussions with several
biotechnology and pharmaceutical companies regarding possible strategic
alliances including joint ventures, mergers or the sale of the Company.
There can be no assurance that the Company will be successful in
consummating a merger or entering into a partnership agreement.  Without
such event, the Company may consider a partial or full liquidation of the
Company, though no such decision has been made at this time.

   Management believes that it will have sufficient assets to fund the
Company's current programs and plans through fiscal 2000 and beyond.

Item 5.	Other Information

        On January 28, 2000, the Company agreed to lend Richard S.
Dondero, a former officer of the Company, an aggregate of $102,158.27, the
amount necessary under stock options then exercisable by Mr. Dondero to
purchase 481,722 shares of the Company's Common Stock under a loan and
pledge agreement.  Under a non-recourse secured promissory note, payment of
the note is required upon on the earliest of: (a) January 1, 2002, (b)
receipt of the proceeds of sale of shares securing the loan, upon the
merger or sale of the Company or (c) the liquidation or dissolution of the
Company.

        On September 1, 1998, the Company entered into a Sponsored
Research Agreement ("Agreement") with Duke University ("Duke") whereby
research was to be performed at Duke to determine the safety and efficacy
of IL-1 beta ("IL-1") as a vaccine adjuvant by way of intranasal
administration in mice utilizing tetanus toxoid and Streptococcus
pneumoniae antigen.  In December 1998, under Amendment 1 of Agreement the
research was extended to June 1999.  In March 1999, under Amendment 2 of
the Agreement, the term of the Agreement was extended through December 31,
1999 and a dosing study was to be performed to determine the safety and
efficacy of IL-1 as a vaccine adjuvant by way of intranasal and
subcutaneous administration in rabbits utilizing tetanus toxoid.  In
September 1999, under Amendment 3 of the Agreement, the term of the
Agreement was extended through March 31, 2000 and during this time a dosing
study is to be performed to determine the safety and efficacy of IL-1 and
an IL-1 mutant as a vaccine adjuvant by way of intranasal and subcutaneous
administration in rabbits utilizing tetanus toxoid.

        In August 1999, the Company entered into a Licensing Agreement
with Duke for exclusive rights by the Company to commercialization of
intranasally administered adjuvants formulated with IL-1b, under patents
owned jointly with Duke or by Duke separately, in return for an immediate
royalty of $100,000 and subsequent contingent  milestone and sales-related
royalties.

                SPONSORED RESEARCH AGREEMENT
                ----------------------------

        This agreement ("Agreement") is between Duke University("Duke"),
a North Carolina non-profit corporation, located in Durham, North Carolina,
and CISTRON Biotechnology, Inc. ("Sponsor"), a Delaware corporation.

        WHEREAS, the research program contemplated by this Agreement is of
mutual interest and benefit to Duke and Sponsor, and will further the
instructional and research objectives of Duke in a manner consistent with
its status as a non-profit educational institution.

        NOW, THEREFORE, the parties agree as follows:

                        ARTICLE 1 - STATEMENT OF WORK
                        -----------------------------
        Duke agrees to use its best effort to perform the research program
described in the "Statement of Work" ("Statement"), a copy of which is
attached to this Agreement as Exhibit A.

                        ARTICLE 2 - INDEPENDENT CONTRACTOR
                        ----------------------------------
        Duke's relationship to Sponsor under this agreement will be that of
an independent contractor and not an agent, joint venturer or partner of
Sponsor.

                        ARTICLE 3 - PRINCIPAL INVESTIGATOR
                        ----------------------------------
        The research will be supervised by Herman F. Staats, Ph.D.
("Investigator") at Duke. If, for any reason Investigator is unable to
continue to serve as Principal Investigator and a successor acceptable to
both Duke and Sponsor is not available, the Agreement will be terminated in
accordance with Article 7 below.

                        ARTICLE 4 - CONSIDERATION
                        -------------------------
        In consideration of the foregoing, and as more specifically provided
in the budget included as Exhibit B, Sponsor will pay Duke for all direct and
indirect costs incurred in the performance of the research as set forth in
the Statement, a total not to exceed $78,543.00. Payment of one third of
the total amount, or $26,181.00, will be due upon signature by Sponsor,
payment of one third of the total amount will be due upon completion of
Project 1, and payment of the remaining one third of the total amount will
be due upon completion of Project 3.

                        ARTICLE 5 - PERIOD OF PERFORMANCE
                        ---------------------------------
        The research will be conducted during an eight-month period commencing
on September 1, 1998 and concluding on or before April 30, 1999. This
agreement will be renewable for additional periods upon the mutual consent
of the parties by a new agreement or by amendment hereto expressed in
writing. Either party may terminate this Agreement on any anniversary date
of this Agreement after the first anniversary date by giving the other
party at least sixty (60) days prior written notice of such

                                - page 1 of 6 -
<PAGE> 2

termination. In the case of such termination, Duke will proceed in an
orderly fashion to terminate any outstanding commitments and to stop the
work as soon as it is practicable to do so. All reasonable costs to Duke
associated with termination will be considered reimbursable costs,
including costs incurred prior to the notice of termination but which have
not yet been reimbursed, and commitments existing at the time the notice
of termination is received which cannot be cancelled.

                        ARTICLE 6 - RESEARCH REPORTS
                        ----------------------------
        Duke will provide Sponsor with one-page biweekly status reports on the
research. In addition, Duke will provide Sponsor with a final report on
such research within sixty (60) days of completion of the research
described herein or termination of this Agreement.

                        ARTICLE 7 - TERMINATION
                        -----------------------
        In the event that either party commits a breach or default in any of
the terms or conditions of this Agreement and that party fails to remedy that
default or breach within thirty (30) days after receipt of written notice
of that breach from the other party, the party giving notice may, at its
option and in addition to any other remedies it may have in law or in
equity, terminate this Agreement by sending written notice of termination
to stop the work as soon as it is practicable to do so. In the case of
termination by Sponsor for reasons other than breach of this Agreement by
Duke, all costs to Duke associated with termination will be considered
reimbursable costs, including costs incurred prior to the notice of
termination but which have not yet been reimbursed, and commitments
existing at the time the notice of termination is received which cannot be
cancelled. In no case will reimbursement under this Agreement exceed the
total estimated project costs specified in Exhibit B.

                        ARTICLE 8 - CONFIDENTIAL INFORMATION
                        ------------------------------------
        "Confidential Information" ("Information") shall mean all information
provided by one party to the other and clearly identified as confidential
by the transmitting party at the time of disclosure. Specifically excepted
from this definition is all information: (a) known by the receiving party
at the time of disclosure; (b) publicly disclosed except by breach of this
Agreement; (c) rightfully received by the receiving party from a third
party without an express obligation of confidence; and (d) independently
developed by the employees or agents of either party without any knowledge
of the confidential information provided by the other party. The party
receiving the Information agrees to hold that Information in trust and
confidence for the transmitting party, using the same care and discretion
that the receiving party uses with similar Information which it considers
confidential. The receiving party will not use Information other than for
the benefit of the two parties and relating to the Agreement and except as
may be provided for in Article 9 regarding publication herein, neither
party will disclose such information without authorization from the other
party. Duke will not disclose the results of the research to third parties
except through the publications provisions of Article 9. This provision
shall remain in effect during the term of this Agreement and for three (3)
years thereafter.

<PAGE> 3

                        ARTICLE 9 - PUBLICATION AND OTHER USE
                        -------------------------------------
        Duke shall be free to use the results of the subject research for its
own teaching, research, educational, clinical and publication purposes without
the payment of royalties or other fees. All such use shall be subject to
the confidentiality provisions of Article 8. Duke agrees to submit to
Sponsor for its review, a copy of any proposed publication resulting from
the subject research at least sixty (60) days prior to the estimated date
of publication, and if no response is received within thirty (30) days of
the date submitted to Sponsor, it will be conclusively presumed that the
publication may proceed without delay. If Sponsor determines that the
proposed publication contains patentable subject matters which require
protection, Sponsor may require the delay of the publication for a period
of time not to exceed sixty (60) days for the purpose of allowing the
pursuit of such protection.

                        ARTICLE 10 - INVENTIONS
                        -----------------------
        It is recognized and understood that certain existing inventions and
technologies are the separate property of Sponsor or Duke and are not
affected by this Agreement, and neither party shall have any claims to or
rights in such separate inventions and technologies. Any new invention,
development, or discovery ("Invention") resulting from the subject
research shall be promptly disclosed in writing to Sponsor. Inventorship
of any such Invention shall be determined in accordance with patent law,
or by mutual agreement based upon the relative contributions of the
parties if the Invention is not patentable. All Inventions that represent
a reduction to practice of Sponsor's conception as described through
written documentation shall be the sole and exclusive property of Sponsor.
Title to other Inventions shall reside with Sponsor if Sponsor personnel
are the sole inventors, with Duke if Duke personnel are the sole
inventors, and will be held jointly if both Duke and Sponsor personnel are
inventors. To the extent that Duke owns the right of sole or joint
inventorship of an Invention, Sponsor is hereby granted, without option
fee other than the consideration of the research sponsored herein and the
reimbursement of Duke for all patent expenses related to the Invention
incurred by Duke prior to and during the option period, an option to
acquire an exclusive, worldwide fee and royalty-bearing license of Duke's
rights to any Invention, which option shall extend for ninety (90) days
after Sponsor's receipt of an Invention disclosure. Upon Sponsor's
exercise of the option, the parties shall promptly negotiate a license
agreement in good faith.

                        ARTICLE 11 - USE OF A PARTY'S NAME
                        ----------------------------------
        Neither party will, without the prior written consent of the other
party: (a) use in advertising, publicity or otherwise, the name of any
employee or agent, any trade-name, trademark, trade device, service mark,
symbol, or any abbreviation, contraction or simulation thereof owned by the
other party, or (b) represent, either directly or indirectly, that any
product or service of the other party is a product or service of the
representing party or that it is made in accordance with or utilizes the
information or documents of the other party. Sponsor may disclose any
information regarding this Agreement required by law to be disclosed.

                        ARTICLE 12 - NOTICE

LICENSED PRODUCTS as follows:

	i.		Fifty thousand dollars ($50,000) upon the issuance of
the first patent in the United States of America based on
DUKE PATENTS; and

	ii.		Twenty five thousand dollars ($25,000) upon the
issuance of the first patent in the United States of
America based on JOINT PATENTS; and

	iii.		Two Hundred Thousand Dollars ($200,000) upon approval

CISTRON in the development of LICENSED PRODUCTS that are
therapeutic vaccines.

	v.		One hundred thousand dollars ($100,000) upon a
decision by PMC to exercise its option to participate with
CISTRON in the development of LICENSED PRODUCTS that are
prophylactic vaccines.

	Such milestone-based royalties shall not be creditable to any
royalty or other fee or payment due to DUKE under this AGREEMENT. All such
milestone fees shall be due and payable thirty (30) days from the
attainment of the milestone by CISTRON.

	b. Commencing with the FIRST COMMERCIAL SALE and at such times
and in such manner set forth hereinafter, CISTRON shall pay to DUKE a
royalty on NET SALES of LICENSED PRODUCTS. Such royalty shall be at the
rate of one-half of one percent (0.5%) of NET SALES.

	c. If CISTRON, its AFFILIATES, or its sublicensees is required
to pay royalties based on net sales to any third party in order to make,
have made, use, or sell LICENSED PRODUCTS in a country, then the royalty
for such LICENSED PRODUCTS in such country payable to DUKE by CISTRON
shall be reduced by fifty-percent (50%) of the amount actually paid by
CISTRON to such third parties; provided, however, that in no event shall
the rate of the royalty paid by CISTRON to DUKE pursuant hereto be less
than one quarter of one percent (0.25%) of NET SALES of such LICENSED
PRODUCTS in such countries.

	d. Beginning with the year that ensues on the second January 1
following the approval of the first LICENSED PRODUCT by the FDA or a
comparable regulatory authority in the European Union, CISTRON shall be
obligated to pay DUKE a minimum annual royalty of Twentyfive Thousand
Dollars ($25,000).

	e. Commencing with the FIRST COMMERCIAL SALE and at such times
and in such manner set

<PAGE> 4

forth hereinafter, CISTRON shall render to DUKE prior to February 28th and
August 31st of each year a written account of the NET SALES of LICENSED
PRODUCTS subject to royalty hereunder made during the prior six (6) month
periods ending December 31st and June 30th, respectively, and shall
simultaneously pay to DUKE the royalties due on such NET SALES in United
States Dollars. Minimum annual royalties, if any, which are due DUKE for
any calendar year, shall be paid by CISTRON along with the written report
due on February 28th of each year. Reports of NET SALES shall reference
DUKE File numbers 1500 and 1689 and shall be made using a form
substantially similar to the model presented in EXHIBIT B of this
AGREEMENT.

	f. CISTRON will make all payments due under this subsections a-d
of this Section 3 on or before the date required by the terms of this
AGREEMENT, or within thirty (30) days of any invoice date on invoices
received from DUKE pursuant to this AGREEMENT. If LICENSEE has not paid
any amount due to DUKE in accordance with this subsection d, DUKE may
increase the amount due (in U.S. Dollars) by an annual percentage rate
equal to one percent (1%) of the amount then due, compounded monthly until
such time as CISTRON has met the full financial obligation due at the time
of the next payment or invoice due date.

	g. Excepting the existing business relationship between CISTRON
and PMC to develop IL1-based vaccine adjuvants, should CISTRON enter into
any strategic alliance, joint venture, partnership or other business
relationship with another commercial party or parties, other than an
AFFILIATED COMPANY, for the purpose of developing or commercializing the
LICENSED PRODUCTS, CISTRON shall pay to Duke the greater of Fifty Thousand
Dollars ($50,000) or ten percent (10%) of the aggregate of any
sublicensing fees or cash payments received by CISTRON pursuant to such
business relationship ("Rights Payments"); provided, however, such Rights
Payments shall specifically exclude amounts received by CISTRON in the
form of research and development funding, equity investments,
performance-based research, development, or commercialization milestone
payments, or sales bonuses. Should any Rights Payments be made in the form
of non-cash consideration, CISTRON and DUKE agree to negotiate in good
faith to determine a cash value for such consideration, and such
determined cash value shall be included in calculating the Rights
Payments, if any, due DUKE. All Rights Payments shall be due and payable
to DUKE by CISTRON thirty (30) days following the later of (i) the event
that obligates CISTRON for such Rights Payments or (ii) the agreement by
DUKE and CISTRON as to the cash value for any non-cash consideration
received by CISTRON which obligates CISTRON for such Rights Payments.

	h. CISTRON shall keep full, true and accurate books of accounts
and other records containing all particulars which may be necessary to
properly ascertain and verify the royalties payable by them hereunder.
Upon DUKE's request, but no more than one time per calendar year, CISTRON
shall permit an independent Certified Public Accountant selected by DUKE
(except one to whom CISTRON has some reasonable objection) to have access
during ordinary business hours to such of CISTRON's records as may be
necessary to determine, in respect of any quarter ending not more than two
(2) years prior to the date of such request, the correctness of any report
and/or payment made under this AGREEMENT.

	i. During the term of this AGREEMENT, representatives of DUKE
will meet with representatives of CISTRON at times and places mutually
agreed upon to discuss the progress and results, as well as the ongoing
plans, with respect to the evaluation and development of the LICENSED
PATENTS; provided, however, that should DUKE's personnel be required by
CISTRON to consult with CISTRON outside of Durham, North Carolina, CISTRON
will reimburse reasonable travel and living expenses incident thereto.

	4.	Representations by DUKE.

	a. DUKE represents that:

	i.		To the best of DUKE's knowledge, DUKE is the sole and
exclusive owner of the entire right, title and interest in
the DUKE PATENTS unencumbered by any outstanding contracts,

1, 2008.

	c.		CISTRON shall inform DUKE within fourteen [14] days of a
decision to terminate the existing business relationship between PMC and
CISTRON or of a decision by PMC not to collaborate with CISTRON to develop
and/or market LICENSED PRODUCTS.

	d.	In the event that PMC and CISTRON decide not to collaborate
to develop and/or market LICENSE PRODUCTS or terminate such a
collaboration, CISTRON shall, within six months following the date of such
a decision or termination, deliver to DUKE a plan reasonably acceptable to
DUKE describing how CISTRON will develop LICENSED PRODUCTS.

	e.	During the term of this AGREEMENT, CISTRON will submit
annual progress reports, including a financial report of moneys spent to

results, as well as ongoing plans, with respect to the LICENSED PATENTS.
DUKE shall have the right to request one meeting per year to discuss such
information.

	f.	DUKE may terminate this AGREEMENT or convert this AGREEMENT
to a non-exclusive agreement if CISTRON fails to meet any of the
commercialization milestones set forth in subsections b-d. of this Section
5. However, in the event that DUKE informs CISTRON that DUKE intends to
convert this AGREEMENT to a non-exclusive license because CISTRON has
failed to meet either of the milestones put forth in Section 5.b. iii. or
Section 5.b.iv, CISTRON may maintain an exclusive license by paying to
DUKE a non-refundable, noncreditable diligence royalty of twenty-five
thousand dollars ($25,000) per year in every year that the development of
LICENSED PRODUCTS is delayed relative to the specified milestone, such
diligence royalty to be paid within thirty (30) days of notification by
DUKE of an intent to convert the license to non-exclusive and on a yearly
basis in any subsequent years.

	6. 	Matters relating to DUKE PATENTS.

	a. Prosecution of DUKE PATENTS. Subsequent to the EFFECTIVE DATE
of this AGREEMENT, DUKE shall continue to have sole responsibility for the
filing, prosecuting and maintaining of appropriate worldwide patents for
the DUKE PATENTS. DUKE shall keep CISTRON advised as to the prosecution of
such

<PAGE> 6
applications by forwarding to CISTRON copies of all official
correspondence relating thereto. CISTRON agrees to cooperate with DUKE in
the prosecution of worldwide patent applications to insure that the
applications reflect, to the best of CISTRON's knowledge, all items of
commercial and technical interest and importance.

	b. US. Patent Expense for DUKE PATENTS. DUKE shall pay for all
expenses prior to and during the term of this AGREEMENT associated with
prosecution and maintenance of patent applications and patents related to
the DUKE PATENTS in the United States of America, and CISTRON shall
reimburse DUKE for all such patent expenses within thirty [30] days of
being invoiced by DUKE.

	c. Foreign Patent Expenses for DUKE PATENTS. DUKE shall request
from CISTRON a written list of foreign countries in which CISTRON wishes
DUKE to prosecute and maintain DUKE PATENTS ("DESIGNATED COUNTRIES"), and
DUKE shall proceed to prosecute and maintain DUKE PATENTS in the
DESIGNATED COUNTRIES. CISTRON shall reimburse DUKE for all expenses
associated with prosecution and maintenance of patent applications and
patents related to the DUKE PATENTS in the DESIGNATED COUNTRIES, such
reimbursement to be made within thirty [30] days of being invoiced. DUKE
shall be free, at its own option and expense, to file patents in foreign
countries that are not DESIGNATED COUNTRIES. CISTRON shall have no rights
under Section 2 of this AGREEMENT to practice patents in countries that
are not DESIGNATED COUNTRIES and no obligation to reimburse DUKE for
patent expenses incurred in pursuing patent protection in countries that
are not DESIGNATED COUNTRIES.

	d. Discontinuance of Patent Support for DUKE PATENTS. CISTRON
may, at its sole option, elect to discontinue reimbursement of patent
expenses incurred during prosecution or maintenance of any individual
patent or patent application within DUKE PATENTS within the United States
or any DESIGNATED COUNTRY by providing DUKE with written notice that it no
longer wishes to reimburse DUKE for such expenses. However, any rights
granted to CISTRON in Section 2 of this AGREEMENT shall be revoked with
respect to any patent application or patent that CISTRON elects not to
support financially, such revocation of rights to become effective
immediately upon receipt by DUKE of written notice from CISTRON that it no
longer wishes to reimburse DUKE for patent expenses for a given patent or
patent application.

	e. Sharing of Patent Expenses with Other Parties Licensing DUKE
PATENTS. DUKE agrees that any license agreement granting rights in DUKE
PATENTS outside the FIELD to third parties shall participate in
reimbursing DUKE for patent expenses related to prosecution and
maintenance of DUKE PATENTS, the share to be paid by each licensee to be
determined by DUKE. DUKE will consider total patent expenses incurred and
the scope of the field licensed by each licensee to determine an equitable
allocation of expenses. DUKE shall inform all licensees when any new
license agreement is executed and what the revised allocation of patent
expenses will be. To the extent a licensee has not paid its allocated
share of such patent expenses, said licensee will be invoiced for
reimbursement of its share of said expenses.

	f. Divisional applications with no claims in the FIELD. In the
event that DUKE is required to respond to a restriction requirement issued
by the United States Patent and Trademark Office or a comparable foreign
agency during prosecution of the DUKE PATENTS and file divisional
applications which do not include claims in the licensed FIELD
[NON-LICENSED DIVISIONALS], CISTRON will have no rights in such
NONLICENSED DIVISIONALS, and no obligation to reimburse DUKE for expenses
incurred by DUKE in prosecuting or maintaining such NON-LICENSED
DIVISIONALS.

	7. 	Matters relating to JOINT PATENTS.

	a. Prosecution of JOINT PATENTS. CISTRON shall have sole
responsibility for the filing, prosecuting and maintaining of appropriate
worldwide patents and patent applications for the JOINT PATENTS using
counsel reasonably acceptable to DUKE, and CISTRON shall pay all expenses
incurred in such activities. CISTRON shall keep DUKE advised as to the
prosecution of such applications by forwarding to DUKE copies of all
official correspondence relating thereto. CISTRON and DUKE agree to
cooperate in the prosecution of worldwide JOINT PATENTS to insure that the
applications reflect, to the best of both parties' knowledge, all items of
commercial and technical interest and importance. CISTRON agrees to allow
DUKE sufficient time to

<PAGE> 7

make suggestions with regard to patent prosecution and to give such
suggestions reasonable consideration. CISTRON will not abandon, nor allow
to go abandoned, any patent application that is included in JOINT PATENTS
without first giving DUKE written notice that CISTRON intends to abandon
such an application, such notice to be given in sufficient time for DUKE
to assume responsibility for prosecution of such JOINT PATENTS. In the
event that DUKE assumes responsibility for prosecuting any JOINT PATENT
that CISTRON intends to abandon, CISTRON shall lose all rights in such
application, and DUKE shall assume full financial responsibility for the
prosecution and maintenance of such an application.

	b. Foreign Patent Filings for JOINT PATENTS. CISTRON shall
supply to DUKE a written list of foreign countries in which CISTRON
intends to prosecute and maintain JOINT PATENTS ("DESIGNATED COUNTRIES"),
DUKE shall be free, at its own option and expense, to file, prosecute, and
maintain JOINT PATENTS in foreign countries that are not DESIGNATED
COUNTRIES. CISTRON shall have no rights under Section 2 of this AGREEMENT
to practice JOINT PATENTS in countries that are not DESIGNATED COUNTRIES.

	8.		Infringement of Third Party Patents. Each party to this
AGREEMENT (here, the "notifying party") shall give the other party to this
AGREEMENT prompt notice of each claim or allegation received by the
notifying party that the manufacture, use or sale of LICENSED PRODUCTS
constitutes an infringement of a third-party patent or patents. CISTRON
shall have the primary right and responsibility at its own expense to
defend and control the defense of any such claim against CISTRON, by
counsel of CISTRON's own choosing. The settlement of any such actions must
be approved by DUKE, which approval may not be unreasonably withheld or
delayed. DUKE agrees to cooperate with CISTRON in any reasonable manner
deemed by CISTRON to be necessary in defending or prosecuting such
actions. CISTRON shall reimburse DUKE for all expenses incurred in
providing such assistance.  Notwithstanding the foregoing, DUKE, shall, in
its sole discretion and at its sole expense, be entitled to participate
through counsel of its own choosing in any such action.

	9.		Infringement by Third Parties. Upon learning of the infringement
of the LICENSED PATENTS by a third party, the party learning of such
infringement shall promptly inform the other party in writing of that fact
along with any evidence available pertaining to the infringement. CISTRON
may at its own expense take whatever steps are necessary to stop the
infringement and recover damages. In such case, CISTRON will keep DUKE
informed of the steps taken and the progress of any legal action taken.
DUKE shall receive twelve and one-half percent (12.5%) of any damages
received in excess of legal expenses incurred by CISTRON in enforcing
rights in the LICENSED PATENTS. If CISTRON does not undertake, within
sixty (60) days of notice, to enforce the rights in the LICENSED PATENTS
against the infringing party, the DUKE shall have the right, at its own
expense to take whatever steps are necessary to stop the infringement and
recover damages and shall be entitled to retain the damages so recovered.

	10.	Government Clearance, Publication, Other Use, Export.

	a. CISTRON agrees that it and its sublicensees will use
reasonable efforts to have the LICENSED PRODUCTS cleared for marketing in
those counties in which CISTRON intends to sell the LICENSED PRODUCTS by
the responsible government agencies requiring such clearance. To
accomplish said clearances at the earliest possible date, CISTRON agrees
to file, according to the usual practice of CISTRON, any necessary data
with said government agencies. Should CISTRON cancel its development
efforts under this AGREEMENT, CISTRON agrees to assign its full interest
and title in such market clearance application, including all data
relating thereto, to DUKE..

	b. DUKE shall be free to publish the results of its continued
research on the subject area of LICENSED PATENTS but agrees to submit to
CISTRON for its review and comment, a copy of any proposed publication
authored by STAATS and resulting from research involving IL1 beta in
vaccine adjuvants at least thirty (30) days prior to the date submitted
for publication, and if no response is received within thirty (30) days of
the date submitted to CISTRON, it will be conclusively presumed that the
publication may proceed without delay. DUKE shall in good faith consider
any comments provided by CISTRON and shall consider the sensitive nature
and

<PAGE> 8

timing of publication of unprotected intellectual property. If CISTRON
determines that the proposed publication contains proprietary subject
matters which require protection, CISTRON may request the delay of the
publication for sixty (60) days from the date first submitted to CISTRON
in order to perfect such protection. Nothing in this AGREEMENT shall be
construed as giving CISTRON editorial control over any publication.
Nothing in this AGREEMENT shall be construed as prohibiting DUKE or
CISTRON from reporting on the results of such research to a governmental
agency if so required by law. For purposes of this AGREEMENT, publication
shall mean the disclosure of information to any person or entity who is
not subject to the confidentiality provisions of Section 13 of this
AGREEMENT.

	c. Except CISTRON's publication review rights set forth in
Section 10.b of this AGREEMENT, nothing in this Section 9 shall be
construed as to restrict DUKE's right to use the LICENSED PATENTS for its
own educational, teaching, and research purposes without restriction.

	d. This AGREEMENT is subject to all United States laws, rules,
and regulations controlling the export of technical data, computer
software, laboratory prototypes and other commodities and technology.

	11.	Duration and Termination.

	a. This AGREEMENT shall become effective upon the EFFECTIVE
DATE, and unless sooner terminated in accordance with any of the
provisions of this AGREEMENT, shall remain in full force and effect until
the last-to-expire of any LICENSED PATENTS, or any extension thereof under
the Waxman-Hatch Act or any other relevant legislation extending patent
life or market exclusivity based on patent protection.

	b. CISTRON may terminate this AGREEMENT by giving DUKE written
notice at least three (3) months prior to such termination, and thereupon
terminate the license granted under this AGREEMENT.

	c. Either party may immediately terminate this AGREEMENT for
fraud, willful misconduct, or illegal conduct of the other party upon
written notice of same to such other party. If either party fails to
fulfill any of its obligations under this AGREEMENT, the non-breaching
party may terminate this AGREEMENT upon written notice to the breaching
party as provided in this subsection c. Such notice must contain a full
description of the event or occurrence constituting a breach of the
AGREEMENT. The party receiving notice of the breach will have the
opportunity to cure the breach within thirty (30) days of receipt of such
notice. If the breach is not cured within such thirty (30) day period, the
termination will be effective as of the thirtieth (30th) day after receipt
of notice.

	d. Upon termination of this AGREEMENT, CISTRON may notify DUKE
of the amount of LICENSED PRODUCT CISTRON then has on hand, and CISTRON
shall then have a license to sell only that amount of the LICENSED
PRODUCT, provided CISTRON shall pay the royalty thereon at the rate and at
the time provided pursuant to this AGREEMENT.

	e. If during the term of this AGREEMENT, CISTRON shall be
adjudicated bankrupt or insolvent or if the business of CISTRON shall be
placed in the hands of a receiver or trustee, whether by the voluntary act
of CISTRON or otherwise, or if CISTRON shall cease to exist as an active
business, this AGREEMENT shall immediately terminate, and DUKE shall have
all remedies and rights available to it for termination with cause.

	12.	Force Majeure.

	a. Neither party shall be considered in breach of its
obligations under this AGREEMENT nor liable for any costs or damages due
to nonperformance under this AGREEMENT arising out of any cause or event
not within the reasonable control of such party and without such party's
fault or negligence, such causes or events being hereinafter referred to
as "Events of Force Majeure."

	b. Each party shall give the other party prompt notice of the
occurrence of any Event of Force Majeure, including such information as is
reasonably necessary to establish the Event of Force Majeure; thereupon,

<PAGE> 9

the obligations of the party giving notice, so far as they are affected by
the Event of Force Majeure, shall be suspended during, but no longer than,
the continuance of the Event of Force Majeure.

        c. Events of Force Majeure shall only excuse delays in
performance and only to the extent such delays are directly attributable
to the Event of Force Majeure. No Event of Force Majeure shall be an
excuse for permanent nonperformance.

        d. Neither party shall be liable for any delay or failure in the
performance of its obligations under this AGREEMENT that directly results
from any failure of the other party to perform its obligations as set
forth in this AGREEMENT.

13.		Confidentiality.

        a. "Confidential Information" means all information, including,
but not limited to, the trade secrets and know-how of the respective
parties which is clearly identified as "Confidential" or "Proprietary" by
the disclosing party at the time of disclosure. If such transmittal occurs
orally, the disclosing party shall identify the oral disclosure as
confidential at the time of disclosure and shall confirm in writing the
confidential nature of such information within thirty (30) days of the
disclosure. Confidential information shall not mean any information that:

        i.      is known to the receiving party at the time of
        disclosure by the disclosing party;
        ii.     is developed independently by the receiving party;

        iii.    is within, or later falls within, the public domain
        without breach of this AGREEMENT by the receiving party;
        iv.     is publicly disclosed with written approval of the
        disclosing party; or

        v.      becomes lawfully known or available to the receiving
        party without restriction from a source having the lawful right to
        disclose the information without breach of this AGREEMENT by the
        receiving party.

        Provided further, the receiving party shall have the burden of proof
as to prior knowledge and absence of breach.

        b. Confidential Information disclosed on a restricted basis
pursuant to a judicial or other lawful government order shall remain
Confidential Information as between the parties and shall only be
disclosed under terms which provide for continued protection of the
information, and, where possible, the disclosing party shall be a party to
the negotiation of the terms for such protection. Notwithstanding any
provision herein to the contrary, this AGREEMENT shall not be construed to
limit the receiving party's obligation and ability to comply with any
judicial or other lawful government order to disclose Confidential
Information on a restricted basis.

	c. Subject to the marking requirements of Section 13.a. of this
AGREEMENT, the obligation of confidentiality under this AGREEMENT shall
apply regardless of the form the Confidential Information takes..

        d. Each party acknowledges that in the performance of this
AGREEMENT it shall receive Confidential Information from the other party
and that such Confidential Information is the exclusive property of the
disclosing party. The receiving party agrees to hold the Confidential
Information of the disclosing party in strict confidence in accordance
with the provisions of this AGREEMENT. A receiving party:

        i.      shall not permit or suffer its employees or agents to
        remove any proprietary or other legends or restrictive
        notices contained or included in any Confidential
        information provided by the disclosing party;

        ii.     shall not permit or suffer its employees or agents to
        copy any Confidential Information,

<PAGE> 10

        except as provided in this AGREEMENT or consented to in
        writing by the disclosing party

        iii.    shall not, except as may be provided in Section 10 of
        this AGREEMENT regarding publication, disclose any
        Confidential Information to a third party without the prior
        written consent of the disclosing party hereto;

        iv.     shall exercise care to keep secure and maintain the
        Confidential Information of the disclosing party in a
        manner no less protective than that used to maintain the
        confidentiality of the receiving party's own Confidential
        Information, but in any event not less  than a reasonable
        degree of care; and

        v.      agrees to use the Confidential Information only to
        further the purposes set forth in this AGREEMENT.

        e. A receiving party may disclose Confidential Information to
officers, employees or agents under the control and direction of the
receiving party only in the normal course of business and on a
need-to-know basis within the purpose of this AGREEMENT. Provided,
however, prior to any disclosure all such officers, employees or agents
shall have entered into written agreements with the receiving party, or
have in place binding policies covering the disclosure of such third-party
Confidential Information and have on file signed acknowledgments of such
binding policies from each officer, employee or agent to which
Confidential Information is disclosed, requiring such officers, employees
or agents to treat and use all such Confidential Information in a manner
consistent with the terms and conditions of this AGREEMENT.

        f. A receiving party's obligation to comply with the
confidentiality provisions of this AGREEMENT with respect to Confidential
Information disclosed by the disclosing party shall extend for a period of
six (6) years from the date of disclosure of Confidential Information.

        g. Upon thirty (30) days written notice from the disclosing
party, the receiving party shall: (i) surrender and deliver all
Confidential Information of the disclosing party, including all copies
thereof; or (ii) with the written consent of the disclosing party, destroy
the Confidential Information and all copies thereof and provide
satisfactory evidence of such destruction to the disclosing party within
one (1) month following said notice. Notwithstanding anything in this
AGREEMENT to the contrary, (i) a receiving party may retain one copy of
each item of Confidential Information disclosed by the disclosing party
solely as evidence of compliance with this AGREEMENT and for no other
purpose, and (ii) upon a request by CISTRON to surrender and deliver all
CISTRON's Confidential Information, DUKE shall be relieved of its
obligation to continue any research dependent upon CISTRON's Confidential
Information.

        14.  Notices. All notices or other communication shall be in writing
and shall be deemed duly given one (1) day after delivery by facsimile,
provided that an originator copy of the notice is deposited in the

                LOAN AND PLEDGE AGREEMENT
                -------------------------

        This Loan and Pledge Agreement (the "Agreement") dated
as of January 28, 2000, by and between Cistron Biotechnology,
Inc., a Delaware corporation ("Cistron"), and Richard S. Dondero
("Dondero").

        1. Cistron hereby loans to Dondero the amount of
$102,158.27 (the "Loan"), on a non-recourse basis secured only
by the Four Hundred Eighty-One Thousand Seven Hundred Twenty-Two
(481,722) shares of Cistron common stock, $.01 par value per
share (the "Shares"), being purchased by Dondero upon exercise
of options to purchase the Shares.

        2. The Loan is evidenced by a non-recourse,
promissory note (the "Note") executed by Dondero in favor of
Cistron, secured by a pledge of the Shares by Dondero.  Dondero
does not assume any personal liability or responsibility for the
failure to pay the principal amount of the Note.  The sole
remedy available upon such failure shall be to proceed against
the Collateral in accordance with the terms of this Agreement.

        3. The Note shall be due and payable in full on the
earliest of January 1, 2002, the merger or sale of Cistron, or

Note shall be due and payable in part or in whole to the extent
provided under paragraph 5.

        4. Dondero agrees to pay to Cistron all expenses
incurred by Cistron, including reasonable attorneys' fees, in
proceeding against the Collateral in which the security interest
is granted under this Agreement.

        5. Dondero agrees to do, execute, acknowledge,
deliver, file and take any and all such other actions as Cistron
may deem necessary or advisable in order to direct Cistron's
transfer agent for its common stock that beginning on the date

transfer agent shall pay all proceeds from the sale of Shares
and any

dividends or other distributions with respect to the Shares
directly to Cistron.  Cistron shall apply such proceeds,
dividends or distributions to the reduction of the principal
amount of the Note.  In connection with any sale of the Shares
prior to the full payment of the Note, Cistron shall deliver the
certificates representing the Shares to the transfer agent for
Cistron's common stock upon receipt of the foregoing proceeds
from any such sale.

        6. Dondero hereby pledges with Cistron as collateral
(the "Collateral") security for the due and punctual payment of
the Note in accordance with its terms and the performance by
Dondero of his obligations under the Note, the Shares (which
include any other securities or property receivable or
distributable with respect thereto after the date hereof).  The
certificate(s) representing the Shares, together with a stock
power(s) attached thereto executed in blank by Dondero, are
being delivered to Cistron and shall be retained by Cistron
until the Note has been paid in full.  At the time the Note
shall have been paid in full, Cistron shall deliver to Dondero
the certificate representing the Shares, together with the stock
power.

        7. So long as no Event of Default (as hereinafter
defined) shall have occurred and be continuing Dondero shall
have the irrevocable proxy to vote and have all other consensual
rights with respect to the Shares, and Cistron shall deliver to
Dondero any proxies, reports or other materials received by it
which are necessary to enable Dondero to exercise such rights.
Upon the occurrence of an Event of Default, all voting and other
consensual rights of Dondero in the Shares shall cease and may
be exercised by Cistron.

        8. Upon the occurrence of an Event of Default,
Cistron shall have and may exercise all rights and remedies
afforded to a secured party under the New Jersey Uniform
Commercial Code, including, without limitation, the right to
sell the Shares at a public or private sale (provided that
Cistron shall give Dondero at least 5 days prior written notice
of the date in

<PAGE> 3

which any public sale is to be held or the date after which any
private sale may be made), at which sale Cistron may purchase
the Shares (free from any right of redemption by Dondero, which
right is hereby waived and released) and have the right to
retain the Shares in full satisfaction of Dondero's obligations
under the Note in accordance with the provisions of the New
Jersey Uniform Commercial Code.

        9. Each of Dondero and Cistron has all power and
authority necessary to enter into and consummate the
transactions contemplated by this Agreement and this Agreement
is valid and enforceable against each of Cistron and Dondero in
accordance with its terms.  Dondero has not created or permitted
any lien or encumbrance to attach to the Shares, other than the
pledge set forth in this Agreement.

        10. If any of the following events ("Events of
Default") shall occur:

            (a) Dondero shall default in the payment of any
part of the principal on the Note when the same shall become due
and payable, whether at maturity, by acceleration or otherwise;

            (b) Dondero shall default in the performance or
compliance with any term or provision contained in this
Agreement;

            (c) Dondero shall (i) become insolvent or be
unable, or admit in writing his inability, to pay his debts as
they mature, (ii) make a general assignment for the benefit of
creditors, (iii) be adjudicated a bankrupt or insolvent or file
a voluntary petition in bankruptcy, (iv) file a petition or an
answer seeking an arrangement with creditors or to take
advantage of any insolvency law or (v) file an answer admitting
to the material obligations of, or consent to, or default in
answering, or fail to have dismissed within 60 days after the
filing thereof, a petition filed against him in any bankruptcy
or insolvency proceeding; or

<PAGE> 4

            (d) If any of the Shares shall be encumbered,
pledged, attached or levied upon or seized at any legal
proceeding; then the holder of the Note may at any time by written
notice to Dondero (or without such notice with respect to subsection
(c) above), declare the entire unpaid principal on the Note to be
forthwith due and payable, without other notices or demands of
any kind, all of which are hereby waived by Dondero.

        11. Dondero will do, execute, acknowledge, deliver,
file and record all such further acts, conveyances, transfers
and assurances as Cistron may deem necessary or advisable to
perfect, preserve, protect and continue the pledge granted by
this Agreement.

        12. All notices and communications provided for
herein shall be delivered or mailed by registered or certified
mail, postage prepaid, or telegraphed, addressed as follows:

If to Cistron at:

        Cistron Biotechnology, Inc.
        10 Bloomfield Avenue

as the recipient party has specified by prior written notice to

        13. All representations and warranties made by
Dondero and Cistron herein shall survive the making of the Loan
and the delivery of the Note hereunder.

        14. No delay on the part of Cistron in exercising any
right, power or privilege hereunder shall operate as a waiver
thereof, nor shall any single or partial exercise of any right,

power or privilege hereunder preclude other or further exercise
thereof, or the exercise of any other right, power or privilege.
The rights and remedies herein provided are cumulative and are
not exclusive of any rights or remedies which Cistron would

under the laws of the State of New Jersey applicable to
agreements made and performed entirely in such State.

        16. This Agreement shall be binding upon the
successors and assigns of the parties hereto; provided, however,
that this Agreement and the Shares shall not be assignable by
Dondero.

        IN WITNESS WHEREOF, the parties hereto have executed
this Agreement as of the date and year first above written.
