                             PLAN OF REORGANIZATION


         THIS AGREEMENT AND PLAN OF REORGANIZATION (the "Agreement") is made and
entered into as of June 23, 1998, by and between CELL PATHWAYS, INC., a Delaware
corporation ("CPI") and TSENG LABS, INC., a Utah corporation ("Target"). Certain
capitalized terms used in this Agreement are defined in Exhibit A.

                                    RECITALS

         WHEREAS, Holdco Company ("Holdco") is a Delaware corporation to be
formed for the purpose of effectuating the transactions contemplated hereby;

         WHEREAS, the Boards of Directors of CPI and Target have each determined
that it is in the best interests of their respective stockholders that each
corporation become a subsidiary of Holdco pursuant to the Mergers (as defined in
Section 1.2 below) and desire to make certain representations, warranties and
agreements in connection with the Mergers;

         WHEREAS, the Boards of Directors of CPI and Target have each determined
that the Mergers and the other transactions contemplated hereby are consistent
with, and in furtherance of, their respective business strategies and goals and
have each approved the Mergers upon the terms and conditions set forth herein;

         WHEREAS, for federal income tax purposes, it is intended that the
formation of Holdco and the Mergers shall constitute one or more tax-free
transactions under the Internal Revenue Code of 1986, as amended (the "Code");
and

         NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants and agreements herein contained, and intending to be legally bound
hereby, the parties hereto hereby agree as follows:



1.      Description of Transaction.

       1.1 Formation of Merger Subsidiaries. CPI will cause the following to
occur: (i) Holdco to be formed under the Delaware General Corporation Law
("DGCL"), (ii) a wholly owned subsidiary of Holdco to be formed to be merged
into CPI ("C-Sub"); and (iii) a wholly owned subsidiary of Holdco to be formed
to be merged into Target ("T-Sub," and together with C-Sub, the "Merger
Subsidiaries"), in each case as set forth in Section 1.2 hereof. Each of the
Merger Subsidiaries will be formed solely to facilitate the Mergers and will
conduct no business or activity other than in connection with the Mergers. CPI
and Target will cause (i) Holdco and the Merger Subsidiaries to execute and
deliver a joinder to this Agreement pursuant to Section 251 of the DGCL, and
(ii) Holdco to execute formal written consents under Section 228 of the DGCL as
the sole stockholder of each of the Merger Subsidiaries, approving the
execution, delivery and performance of this Agreement by each of the Merger
Subsidiaries.



                                       1
<PAGE>


         1.2 The Mergers. At the Effective Time (as defined in Section 1.3
hereof) and subject to and upon the terms and conditions of this Agreement and
the DGCL: (i) C-Sub shall be merged with and into CPI, the separate corporate
existence of C-Sub shall cease, and CPI shall continue as the surviving
corporation that shall be a wholly owned subsidiary of Holdco; and (ii) T-Sub
shall be merged with and into Target, the separate corporate existence of T-Sub
shall cease, and Target shall continue as the surviving corporation that shall
be a wholly owned subsidiary of Holdco. The mergers described in clauses (i) and
(ii) of the immediately preceding sentence are herein collectively referred to
as the "Mergers" and each individually as a "Merger." CPI and Target, as the
surviving corporations after the Mergers, are herein collectively referred to as
the "Surviving Corporations" and each individually as a "Surviving Corporation"
and C-Sub and T-Sub as the non-surviving corporations after the Mergers are
herein sometimes collectively referred to as the "Merged Corporations" and each
as a "Merged Corporation." Holdco, CPI, Target, and, individually after entering

per share ("CPI Common Stock"), and CPI Preferred Stock, par value $0.01 per
share ("CPI Preferred Stock"), issued and outstanding immediately before the

Target) and all rights in respect thereof, shall at the Effective Time, without
any action on the part of any holder thereof, forthwith cease to exist and be

those owned by CPI) and all rights in respect thereof, shall at the Effective
Time, without any action on the part of any holder thereof, forthwith cease to

and the Target Exchange Ratio being referred to herein collectively as the
"Exchange Ratios").

                            (iii) Commencing immediately after the Effective
Time, each certificate that, immediately prior to the Effective Time,
represented issued and outstanding shares of CPI Common Stock and CPI Preferred

                  (c) Conversion of Common Stock of the Merged Corporations into
Common Stock of the Surviving Corporations.

                            (i) At the Effective Time, each share of Common
Stock, par value $0.01 per share, of C-Sub issued and outstanding immediately
prior to the Effective Time, and all rights in respect thereof, shall, without
any action on the part of Holdco, forthwith cease to exist and be converted into
one validly issued, fully paid and nonassessable share of Common Stock of CPI,
par value $0.01 per share, as one of the Surviving Corporations (the "New CPI
Common Stock"). Immediately after the Effective Time and upon surrender by
Holdco of the certificate representing the shares of the common stock of C-Sub,
CPI as one of the Surviving Corporations shall deliver to Holdco an appropriate
certificate or certificates representing the New CPI Common Stock created by
conversion of the common stock of C-Sub owned by Holdco.

                            (ii) At the Effective Time, each share of Common
Stock, par value $0.01 per share, of T-Sub issued and outstanding immediately
prior to the Effective Time, and all rights in respect thereof, shall, without
any action on the part of Holdco, forthwith cease to exist and be converted into
one validly issued, fully paid and nonassessable share of common stock of
Target, par value $0.01 per share, as one of the Surviving Corporations (the
"New Target Common Stock"). Immediately after the Effective Time and upon
surrender by Holdco of the certificate representing the shares of the common
stock of T-Sub, Target as one of the Surviving Corporations shall deliver to
Holdco an appropriate certificate or certificates representing the New Target
Common Stock created by conversion of the common stock of T-Sub owned by Holdco.

                  (d) Exchange of Shares Other Than Treasury Shares. Subject to
the terms and conditions hereof, at or prior to the Effective Time, Holdco shall
appoint an exchange agent to effect the exchange of Shares for Holdco Common
Stock in accordance with the provisions of this Section 1.7 (the "Exchange
Agent"). From time to time after the Effective Time, Holdco shall deposit, or
cause to be deposited, certificates representing Holdco Common Stock for
conversion of Shares in accordance with the provisions of Section 1.7(a) hereof
(such certificates, together with any dividends or distributions with respect
thereto, being herein referred to as the "Exchange Fund"). Commencing
immediately after the Effective Time and until the appointment of the Exchange
Agent shall be terminated, each holder of a certificate or certificates
theretofore representing Shares may surrender the same to the Exchange Agent,
and, after the appointment of the Exchange Agent shall be terminated, any such
holder may surrender any such certificate to Holdco. Such holder shall be
entitled upon such surrender to receive in exchange therefor a certificate or
certificates representing the number of full shares of Holdco Common Stock into
which the Shares theretofore represented by the certificate or certificates so
surrendered shall have been converted in accordance with the provisions of
Section 1.7(a) hereof, together with a cash payment in lieu of fractional
shares, if any, in accordance with Section 1.7(f) hereof, and all such shares of
Holdco Common Stock shall be deemed to have been issued at the Effective Time.
Until so surrendered and exchanged, each outstanding certificate that, prior to
the Effective Time, represented issued and outstanding Shares shall be deemed
for all corporate purposes of Holdco, other than the payment of dividends and
other distributions, if any, to evidence ownership of the number of full shares
of Holdco Common Stock into which the Shares theretofore represented thereby
shall have been converted at the Effective Time. Unless and until any such
certificate theretofore representing Shares is so surrendered, no dividend or
other distribution, if any, payable to the holders of record of Holdco Common
Stock as of any date subsequent to the Effective Time shall be paid to the
holder of such certificate in respect thereof. Upon the surrender of any such
certificate theretofore representing Shares, however, the record holder of the
certificate or certificates representing shares of Holdco Common Stock issued in
exchange therefor shall receive from the Exchange Agent or from Holdco, as the
case may be, payment of the amount of dividends and other distributions, if any,
which as of any date subsequent to the Effective Time and until such surrender
shall have become payable with respect to such number of shares of Holdco Common
Stock ("Pre-Surrender Dividends"). No interest shall be payable with respect to
the payment of Pre-Surrender Dividends upon the surrender of certificates
theretofore representing Shares. After the appointment of the Exchange Agent
shall have been terminated, such holders of Holdco Common Stock that have not
received payment of Pre-Surrender Dividends shall look only to Holdco for
payment thereof. Notwithstanding the foregoing provisions of this Section
1.7(d), neither the Exchange Agent nor any Party shall be liable to a holder of
Shares for any Holdco Common Stock or dividends or distributions thereon
delivered to a public official pursuant to any applicable abandoned property,
escheat or similar law or to a transferee pursuant to Section 1.7(e) hereof.

                  (e) Transfer Books. The stock transfer books of CPI with
respect to the CPI Shares and the stock transfer books of Target with respect to
the Target Shares shall each be closed at the Effective Time and no transfer of
any Shares will thereafter be recorded on any of such stock transfer books. In
the event of a transfer of ownership of Shares that is not registered in the
stock transfer records of CPI or Target, as the case may be, at the Effective
Time, a certificate or certificates representing the number of full shares of
Holdco Common Stock into which such Shares shall have been converted shall be
issued to the transferee together with a cash payment in lieu of fractional
shares, if any, in accordance with Section 1.7(f) hereof, and a cash payment in
the amount of Pre-Surrender Dividends, if any, in accordance with Section 1.7(d)
hereof, if the certificate or certificates representing such Shares is or are
surrendered as provided in Section 1.7(d) hereof, accompanied by all documents
required to evidence and effect such transfer and by evidence of payment of any
applicable stock transfer tax.

                  (f)      No Fractional Share Certificates.

                            (i) No scrip or fractional share certificate for
Holdco Common Stock will be issued upon the surrender for exchange of
certificates evidencing Shares. CPI and Target shall cause Holdco to pay to the
Exchange Agent an amount sufficient for the Exchange Agent to pay each holder of
Target Common Stock an amount in cash equal to the product obtained by
multiplying (i) the fractional share interest to which such holder would
otherwise be entitled (after taking into account all shares of Target Common
Stock held at the Effective Time by such holder) by (ii) the closing price of a
share of Target Common Stock on the Nasdaq National Market on the trading day
immediately preceding the Effective Time divided by the Target Exchange Ratio.

<PAGE>

                            (ii) As soon as practicable after the determination
of the amount of cash, if any, to be paid to holders of Target Common Stock with
respect to any fractional share interests, the Exchange Agent shall make
available such amounts, net of any required withholding, to such holders of
Target Common Stock, subject to and in accordance with the terms of Section
1.7(d) hereof.

                            (iii) Any portion of the Exchange Fund that remains
undistributed for six months after the Effective Time shall be delivered to
Holdco, upon demand, and any holders of CPI Common Stock, CPI Preferred Stock or
Target Common Stock who have not theretofore complied with the provisions of
this Section 1.7 shall thereafter look only to Holdco for satisfaction of their
claims for Holdco Common Stock or any cash in lieu of fractional shares of
Holdco Common Stock and any Pre-Surrender Dividends.

                  (g)      Options and Warrants.

                            (i) At the Effective Time, each option or warrant
granted by CPI to purchase shares of CPI Common Stock or CPI Preferred Stock,
and each Target Option, which is outstanding and unexercised immediately prior
to the Effective Time, shall be assumed by Holdco and be converted into an
option or warrant to purchase shares of Holdco Common Stock in such amount and
at such exercise price as provided below and otherwise having the same terms and
conditions as are in effect immediately prior to the Effective Time (except to
the extent that such terms, conditions and restrictions may be altered in
accordance with their terms as a result of the transactions contemplated
hereby):

                                    (1) the number of shares of Holdco Common
Stock to be subject to the new option or warrant shall be equal to the product
of (x) the number of shares of CPI Common Stock, CPI Preferred Stock or Target
Common Stock subject to the original option or warrant and (y) the CPI Exchange
Ratio (if the original option or warrant related to CPI Common Stock or CPI
Preferred Stock) or the Target Exchange Ratio (if the original option or warrant
related to Target Common Stock), respectively;

                                    (2) the exercise price per share of Holdco
Common Stock under the new option or warrant shall be equal to (x) the exercise
price per share of the CPI Common Stock, CPI Preferred Stock or Target Common
Stock under the original option or warrant divided by (y) the CPI Exchange Ratio
(if the original option or warrant related to CPI Common Stock or CPI Preferred
Stock) or the Target Exchange Ratio (if the original option or warrant related
to Target Common Stock); and

                                    (3) upon each exercise of options or
warrants by a holder thereof, the aggregate number of shares of Holdco Common
Stock deliverable upon such exercise shall be rounded down, if necessary, to the
nearest whole share and the aggregate exercise price shall be rounded up, if
necessary, to the nearest cent. The adjustments provided herein with respect to
any options that are "incentive stock options" (as defined in Section 422 of the
Code) shall be effected in a manner consistent with Section 424(a) of the Code.

<PAGE>

                  (h) Certain Adjustments. If between the date of this Agreement
and the Effective Time, the outstanding shares of CPI Common Stock, CPI
Preferred Stock or of Target Common Stock shall be changed into a different
number of shares by reason of any reclassification, recapitalization, split-up,
combination or exchange of shares, or any dividend payable in stock or other
securities shall be declared thereon with a record date within such period, the
exchange ratio established pursuant to the provisions of Section 1.7(a) hereof
shall be adjusted accordingly to provide to the holders of CPI Common Stock, CPI
Preferred Stock and Target Common Stock the same economic effect as contemplated
by this Agreement prior to such reclassification, recapitalization, split-up,
combination, exchange or dividend.

         1.8 CPI Charter Amendment. The Board of Directors of CPI has approved
an amendment to CPI's Certificate of Incorporation attached hereto as Exhibit C
(the "CPI Charter Amendment"), in order to effectuate the consummation of the
Mergers. CPI shall file the CPI Charter Amendment immediately prior to the
Effective Time.

applicable requirements of the Securities Act or the Exchange Act (as the case
may be); and (ii) none of the Target SEC Documents contained any untrue

consummation of the Mergers or any of the other transactions contemplated by
this Agreement, will result in any payment (including any bonus, golden
parachute or severance payment) to any of Target's current or former employees
or directors (whether or not under any Target Plan), or materially increase the
benefits payable under any Target Plan, or result in any acceleration of the
time of payment or vesting of any such benefits.

property or trade secret, owned or claimed by another. CPI has not received any

not aware of any reason why any such letter should be revoked.

                  (j) Except as set forth in the CPI Disclosure Schedule,
neither the execution, delivery or performance of this Agreement, nor the
consummation of the Merger or any of the other transactions contemplated by this
Agreement, will result in any payment (including any bonus, golden parachute or
severance payment) to any current or former employee or director of CPI (whether
or not under any CPI Plan), or materially increase the benefits payable under
any CPI Plan, or result in any acceleration of the time of payment or vesting of
any such benefits.

or other Contract with a labor union involving any of its employees.

respects with all applicable Environmental Laws, which compliance includes the

under applicable Environmental Laws, and compliance with the terms and
conditions thereof. CPI has not received any notice or other communication (in
writing or otherwise), whether from a Governmental Body, citizens group,
employee or otherwise, that alleges that CPI is not in compliance with any
Environmental Law. To the knowledge of CPI without further inquiry, no current
or prior owner of any property leased or controlled by CPI has received any
notice or other communication (in writing or otherwise), whether from a
Government Body, citizens group, employee or otherwise, that alleges that such
current or prior owner or CPI is not in compliance with any Environmental Law.
To the best knowledge of CPI, all property that is leased to, controlled by or
used by CPI, and all surface water, groundwater and soil associated with or
adjacent to such property is in clean and healthful condition and is free of any
material environmental contamination of any nature. To the best knowledge of
CPI, CPI has not disposed of, emitted, discharged, handled, stored, transported,
used or released any Materials of Environmental Concern, arranged for the
disposal, discharge, storage or release of any Materials of Environmental
Concern, or exposed any employee or other individual to any Materials of
Environmental Concern or condition so as to give rise to any material liability
or material corrective or remedial obligation under any Environmental Laws.

regarding any actual or possible (a) cancellation or invalidation of any

                  (a) Since December 31, 1997, except as set forth in the CPI

making illegal or otherwise interfering with, the Merger or any of the other
transactions contemplated by this Agreement. To the best of the knowledge of
CPI, no event has occurred, and no claim, dispute or other condition or
circumstance exists, that could reasonably be expected to give rise to or serve
as a basis for the commencement of any such Legal Proceeding that would
reasonably be expected to have a Material Adverse Effect on CPI.

                  (b) There is no material order, writ, injunction, judgment or
decree to which CPI, or any of the assets owned or used by CPI, is subject. To
the best of the knowledge of CPI, no officer or key employee of CPI is subject

however that Target (i) shall provide CPI with at least 48 hours prior written

Proposal and any material modification or proposed modifications thereto.

                  (d) Target shall immediately cease and cause to be terminated

contained in this Agreement shall be or shall have become materially inaccurate,

                                 HOLDCO COMPANY



                                       I.

         The name of the corporation is Holdco Company (the "Corporation").

                                       II.

         The address of the registered office of the Corporation in the State of

name of the registered agent of the Corporation in the State of Delaware at such
address is Corporation Service Company.

                                      III.

         The purpose of the Corporation is to engage in any lawful act or
activity for which a corporation may be organized under the General Corporation
Law of the State of Delaware.

                                       IV.

         A. The Corporation shall be authorized to issue two classes of stock to
be designated, respectively, "Common Stock" and "Preferred Stock". The total
number of shares that the Corporation shall be authorized to issue is
seventy-five million (75,000,000) shares. Seventy million (70,000,000) shares
shall be Common Stock, each having a par value of One Cent ($.01). Five million
(5,000,000) shares shall be Preferred Stock, each having a par value of One Cent

         B. The Preferred Stock may be issued from time to time in one or more
series. The Board of Directors is hereby authorized, by filing a certificate (a
"Preferred Stock Designation") pursuant to the Delaware General Corporation Law,
to provide for such issuance, and to fix or alter from time to time the
designation, powers, preferences and rights of the shares of each such series
and the qualifications, limitations or restrictions of any wholly unissued
series of Preferred Stock, and to establish from time to time the number of
shares constituting any such series or any of them; and to increase or decrease
the number of shares of any series subsequent to the issuance of shares of that
series, but not below the number of shares of such series then outstanding. In
case the number of shares of any series shall be decreased in accordance with
the foregoing sentence, the shares constituting such decrease shall resume the
status that they had prior to the adoption of the resolution originally fixing
the number of shares of such series.

         C. Subject to the rights of any Preferred Stock then outstanding, each
issued and outstanding share of Common Stock shall entitle the Holder thereof to
receive such dividends as may be declared from time to time by the Board of
Directors of the Corporation out of funds legally available therefor, and shall
entitle the Holder thereof to share ratably with other Holders of Common Stock
in all assets available for distribution in the event of any liquidation,
dissolution or winding up of the Corporation. Each issued and outstanding share
of Common Stock shall be identical to all other shares of that class, and shall
entitle the Holder thereof to cast one vote on each matter submitted to a vote
of the Corporation's stockholders. No Holder of Common Stock shall be entitled
to any cumulative voting rights or to any preemptive rights upon the issuance or
sale of any Securities.

         For the management of the business and for the conduct of the affairs
of the Corporation, and in further definition, limitation and regulation of the
powers of the Corporation, of its directors and of its stockholders or any class
thereof, as the case may be, it is further provided that:

               A. 1. The business and affairs of the Corporation shall be
managed by or under the direction of the Board of Directors. The number of
directors that shall constitute the whole Board of Directors shall be fixed
exclusively by one or more resolutions adopted by the Board of Directors.

                  2. Subject to the rights of the holders of any series of
Preferred Stock to elect additional directors under specified circumstances, the
directors shall be divided into three classes designated as Class I, Class II
and Class III, respectively. Directors shall be assigned to each class in
accordance with a resolution or resolutions adopted by the Board of Directors.
At the first annual meeting of stockholders following the filing of this
Certificate of Incorporation, the term of office of the Class I directors shall
expire and Class I directors shall be elected for a full term of three years. At
the second annual meeting of stockholders following the filing of this
Certificate of Incorporation, the term of office of the Class II directors shall

shall expire and Class III directors shall be elected for a full term of three
years. At each succeeding annual meeting of stockholders, directors shall be
elected for a full term of three years to succeed the directors of the class
whose terms expire at such annual meeting.

                  Each director shall serve beyond the term specified until his
successor is duly elected and qualified or until his death, resignation or
removal. No decrease in the number of directors constituting the Board of
Directors shall shorten the term of any incumbent director.

                  3. Subject to the rights of the holders of any series of
Preferred Stock, a director may be removed only for cause and only by the

then-outstanding shares of voting stock of the Corporation, entitled to vote at
an election of directors (the "Voting Stock").

directorships resulting from any increase in the number of directors, shall,
unless the Board of Directors determines by resolution that any such vacancies
or newly created directorships shall be filled by the stockholders, be filled
only by the affirmative vote of a majority of the directors then in office, even
though less than a quorum of the Board of Directors, and not by the
stockholders. Any director elected in accordance with the preceding sentence
shall hold office for the remainder of the full term of the director for which
the vacancy was created or occurred and until such director's successor shall
have been elected and qualified.

                  5. The Board of Directors shall designate and empower
committees of the Board of Directors, shall elect and empower the officers of
the Corporation, may appoint and empower other officers and agents of the
Corporation, and shall determine the time, place and notice of Board meetings,

to the other provisions of this Article V, the Board of Directors shall
determine the rights, powers, duties, rules and procedures that shall affect the
directors' power to manage and direct the business and affairs of the
Corporation. Notwithstanding any other provision of this Certificate of
Incorporation, the powers specified in this Article V shall be exercised only by
or under the direction of the Board of Directors and may be exercised or
expressed in the form of resolution, Bylaw or other form of determination or
exercise; and the form of the exercise of the power shall not derogate the
status of the power exercised or imply that such exercise by the Board of
Directors may be altered or superseded by any person, group or entity other than
the Board of Directors.

               B. 1. Subject to paragraph (h) of Section 43 of the Bylaws, the
Bylaws may be altered or amended or new Bylaws adopted by the affirmative vote
of at least sixty-six and two-thirds percent (66-2/3%) of the voting power of
all of the then-outstanding shares of the Voting Stock. The Board of Directors
shall also have the power to adopt, amend, or repeal Bylaws.

                  2. The directors of the Corporation need not be elected by
written ballot unless the Bylaws so provide.

                  3. No action shall be taken by the stockholders of the
Corporation except at an annual or special meeting of stockholders called in
accordance with the Bylaws or by unanimous written consent of the stockholders.

                  4. Special meetings of the stockholders of the Corporation may
be called, for any purpose or purposes, by (i) the Chairman of the Board of
Directors, (ii) the Chief Executive Officer, or (iii) the Board of Directors
pursuant to a resolution adopted by a majority of the total number of authorized
directors (whether or not there exist any vacancies in previously authorized
directorships at the time any such resolution is presented to the Board of
Directors for adoption), and shall be held at such place, on such date, and at
such time as the Board of Directors shall fix.

of directors and of business to be brought by stockholders before any meeting of
the stockholders of the Corporation shall be given in the manner provided in the
Bylaws of the Corporation.

                                       VI.

         A. A director of the Corporation shall not be personally liable to the
Corporation or its stockholders for monetary damages for any breach of fiduciary
duty as a director, except for liability (i) for any breach of the director's
duty of loyalty to the Corporation or its stockholders, (ii) for acts or
omissions not in good faith or that involve intentional misconduct or a knowing
violation of law (iii) under Section 174 of the Delaware General Corporation
Law, or (iv) for any transaction from which the director derived an improper
personal benefit. If the Delaware General Corporation Law is amended after
approval by the stockholders of this Article to authorize corporate action
further eliminating or limiting the personal liability of directors, then the
liability of a director shall be eliminated or limited to the fullest extent
permitted by the Delaware General Corporation Law, as so amended.

         B. Any repeal or modification of this Article VI shall be prospective
and shall not affect the rights under this Article VI in effect at the time of
the alleged occurrence of any act or omission to act giving rise to liability or
indemnification.

                                      VII.

         A. The Corporation reserves the right to amend, alter, change or repeal
any provision contained in this Certificate of Incorporation, in the manner now
or hereafter prescribed by statute, except as provided in Section B of this

FOR IMMEDIATE RELEASE
- ---------------------


                  CELL PATHWAYS AND TSENG LABS AGREE TO COMBINE
                  ---------------------------------------------

         HORSHAM, PA (June 23, 1998): Cell Pathways, Inc. ("CPI") of Horsham, PA
and Tseng Labs, Inc. ("Tseng") of Norristown, PA (Nasdaq National Market:TSNG)
today announced that they have signed a definitive agreement whereby the
stockholders of Tseng will exchange all of their stock tax-free for
approximately 5.5 million shares of Common Stock of CPI, representing an equity
interest of approximately 23%. The transaction will require the approval of the
stockholders of both companies. Upon completion of the transaction, scheduled
for October 1998, the stock of CPI will be listed for trading on the Nasdaq
National Market. Tseng currently has 15,084,337 shares of common stock
outstanding. Based on the closing price of Tseng stock on the Nasdaq National
Market on Tuesday, June 23, 1998 of $ 2.69, the proposed transaction has a total
value of approximately $177 million.

         Jack Gibbons, President and Chief Executive Officer of Tseng,
commented, "After an analysis of nearly 100 possible transactions, and a careful
review by independent experts, we chose this transaction and sincerely believe
it is an outstanding opportunity for the shareholders of Tseng to participate in
a company with exciting future prospects."

         "The completion of this transaction will provide CPI with additional
financial resources to continue the aggressive clinical development of our lead
compound, FGN-1(TM) exisulind, in the prevention and treatment of several of the
most common and deadly forms of cancer," said Robert J. Towarnicki, President
and CEO of Cell Pathways. "In addition, it will allow us to accelerate the
preclinical development of some of the most promising new anticancer compounds
in our research pipeline." Mr. Towarnicki will become President and CEO of the
combined company.

Cell Pathways and Tseng Labs to Combine

         In December of 1997, Tseng sold substantially all of its graphics
development assets and sought to convert its largely cash assets into
investments in a growth-stage company or companies in the late stage of product
development.

         CPI is a privately-owned pharmaceutical company focused on the
development and commercialization of products to prevent and treat cancer. CPI
has started or is planning clinical trials of its lead compound FGN-1(TM)
exisulind in seven indications (an "indication" is a disease, symptom or medical
sign or circumstance for which the product is to be used). CPI is conducting an
on-going pivotal Phase III trial for Adenomatous Polyposis Coli (APC), a disease
characterized by numerous precancerous polyps of the colon. In December 1997,
CPI initiated Phase II/III trials of FGN-1 for the treatment of sporadic
adenomatous colonic polyps, and for the prevention of prostate cancer
recurrence, as well as a pilot study in lung cancer. In February 1998, CPI
initiated a Phase II/III trial of FGN-1 for the prevention of breast cancer
recurrence. CPI also plans to initiate Phase II trials for the treatment of
Barrett's Esophagus and cervical dysplasia in 1998.

         CPI's technology is based upon its discovery of a novel mechanism which
the company believes, based on its research, can be targeted to induce selective
apoptosis, or programmed cell death in precancerous and cancerous cells without
affecting normal cells. Utilizing this proprietary knowledge, the company has
created over 400 new chemical compounds, over 200 of which display significantly
greater apopotic potency than exisulind.

         Cell Pathways Inc. was founded in 1990 and has completed seven rounds
of private equity financing. Investors in these private equity financings have
included: Canaan Partners, Gem Capital Management, Goldman Sachs, New York Life
Insurance Company, Northwood Ventures, Quest Ventures, Technology Partners, and
Vulcan Northwest. In its most recent financings, CPI raised $17.6 million in the
spring of 1997 and $21.6 million in the spring of 1998. Following the
combination of CPI and Tseng, CPI expects to have $45 million in cash and cash
equivalents, and approximately 24 million shares of common stock outstanding.
Financial advice regarding this transaction was provided to CPI by Salomon Smith
Barney and to Tseng by Janney Montgomery Scott.

management and are subject to various risks and uncertainties that may influence
Tseng's ability to execute its acquisition strategy and other risks as detailed
from time to time in Tseng's SEC reports and filings.
