ITEM 5.  OTHER EVENTS

        On June 16, 1998, Techniclone Corporation, a Delaware corporation (the
"Registrant" or the "Company") and two (2) private investors ("Subscribers")
entered into a Regulation D Common Stock Equity Line Subscription Agreement, a
Registration Rights Agreement and a Warrant, pursuant to which the Company may,
in its sole discretion, and subject to certain restrictions, periodically sell
("Put") shares of the Company's Common Stock for up to $20,000,000 upon the
effective registration of such Put shares. At the time of each Put, the
Subscriber will be issued a Warrant which will give the holder the right, until
December 31, 2004, to purchase up to 10% of the amount of Common Stock issued
pursuant to the Put at the price paid for the Common Stock. After the Company
has an effective registration statement for the Put shares, unless an increase
is otherwise agreed to, $2,250,000 of Puts can be made every quarter, subject to
share issuance volume limitations identical to those set forth in Rule 144(e).
The number of shares of Common Stock to be issued on each Put will depend upon
the Market Price (as that term is defined in the Agreement) of the Common Stock
at the time of each Put. The Company is limited in the amount of the Put if the
price of the Common Stock is $1.00 or less and it is unable to make any Puts if
the minimum share price is $.50 or lower. At the time of each Put, each
Subscriber receives a discount of 15% from the then current Market Price. The
Company is required to pay placement agent fees consisting of cash, shares of
Common Stock and a Warrant to the Placement Agent on the closing of each Put. If
the Company does not exercise the full amount of its Put rights, then the
Company will issue "Commitment Warrants" on the first, second and third
anniversary of this Agreement. The amount of Commitment Warrants to be issued
will be equal to the difference of $6,666,666, $13,333,333 and $20,000,000
("Commitment Amounts"), respectively, less the actual cumulative total dollar
amount of Puts which have been exercised to such anniversary date. On each such
anniversary date the Company will issue that number of shares equal to ten
percent (10%) of the shares of Common Stock which would be issued by
subtracting the actual cumulative dollar amount of Puts for such anniversary
date from the Commitment Amounts on such anniversary date and dividing the
answer by the Market Price.

        The Regulation D Common Stock Equity Line Subscription Agreement
provides for the Company to sell Common Stock to the Subscribers at times which
the Company decides is advantageous. The Equity Line Subscription Agreement is
not a credit instrument. Any Put exercised by the Company is a sale of Common
Stock and not a loan.

        In connection with the issuance of shares of Common Stock pursuant to
the Equity Line Subscription Agreement, the Registrant agreed to pay the
placement agent a non-accountable expense allowance of 1% of the first
$10,000,000 raised, a cash commission of seven percent (7%) of the Purchase
Price of the Common Stock issued to the Subscribers, Common Stock equal to eight
percent (8%) of the Common Stock issued to the Subscribers, a Warrant to
purchase eight percent (8%) of the Common Stock issuable pursuant to the Warrant
issued to Subscribers, and after $10,100,000 is invested in the Company by
Subscribers, an additional non-accountable expense allowance of $100,000. As set
forth in the Agreement between the Company and the placement agent, the
placement agent will, in addition to assisting with the Equity Line Subscription
Agreement, provide the Company with investor relations services for one year.

        On the first Put, the Company issued 2,545,454 restricted shares of the
Company's Common Stock for $3,500,000 pursuant to the Equity Line Subscription
Agreement ("Initial Tranche"). One half of the Initial Tranche is subject to
adjustment at three months after the effective date of the registration
statement registering these shares, and the second half of the initial tranche
will be subject to an adjustment at six months after such effective date
registering these shares. At each adjustment date, if the Market Price at such
three or six month period is less than the initial price paid for the Common
Stock ("Adjustment Price"), then for such half of the initial tranche, the
Company will be required to issue additional shares of Common Stock equal to the
difference between the amount of shares which would have been issued if the
price had been the Adjustment Price at the time of issuance, less the amount
originally issued. The Company also will be required to issue additional
Warrants at each three month and six month Adjustment Price for ten percent
(10%) of any additional shares issued.

        The Company intends to use the proceeds of the offering to continue its
clinical trials of Oncolym(TM) and TNT and for general corporate and working
capital purposes.

case may be, required to be issued by the Company, minus (ii) the number of the
Cap Limit Shares, times (b) the Three Month Reset Price or the Six Month Reset

and Initial Tranche Shares.

                             (a) Adjustment Due to Stock Split or Combination.
If, at any time, after the Initial Tranche Closing Date but prior to either the
Three Month Reset Date or the Six Month Reset Date, as the case may be, the
number of outstanding shares of Common Stock is increased by a stock split,
stock dividend, or other similar event, or decreased by a combination or
reclassification of shares, or other similar event, then the Three Month Reset
Price or the Six Month Reset Price, as the case may be, shall be calculated
giving appropriate effect to the stock split, stock dividend, combination,
reclassification or other similar event.

                             (b) Adjustment Due to Merger, Consolidation, Etc.
If, after the Initial Tranche Closing Date but prior to either the Three Month
Reset Date or the Six Month Reset Date, as the case may be, there shall be any
merger, consolidation, exchange of shares, recapitalization, reorganization, or
other similar event (a "Reset Transaction"), as a result of which shares of
Common Stock of the Company shall be changed into (or the shares of Common Stock
become entitled to receive) the same or a different number of shares of the same
or another class or classes of stock or securities of the Company or another
entity, then, prior to the consummation of any Reset Transaction, the Company
will make appropriate provision (in form and substance reasonably satisfactory
to the Subscriber) to insure that the Subscriber shall thereafter have the right
to acquire and receive, upon the basis and upon the terms and conditions
specified herein and in lieu of or addition to (as the case may be) the shares
of Common Stock theretofore issuable upon such Three Month Reset Date or Six
Month Reset Date, as the case may be, such stock, securities and/or other assets
that would have been issued or payable in such Reset Transaction with respect to
or in exchange for the number of shares of Common Stock which would have been
acquirable or receivable upon the Three Month Reset Date or Six Month Reset
Date, as the case may be, had such Reset Transaction not taken place. In any
such case, the Company will make appropriate provision (in form and substance
reasonably satisfactory to the Subscriber) with respect to the Subscriber's
rights and interests to insure that the provisions of this Section 2.2.7(b) and
Section 2.2.2 will thereafter be enforceable and to give appropriate effect to
the reset provisions in Section 2.2.2(a) and Section 2.2.2(b) (including, in the
case of any such Reset Transaction in which the successor entity or purchasing
entity is other than the Company, an immediate revision of the Initial Tranche
Share Price to reflect the price of the common stock of the surviving entity and
the market in which such common stock is traded). The Company shall not effect
any transaction described in this Section 



                                      -18-
   15

2.2.7(b) unless the resulting successor or acquiring entity (if not the Company)
assumes by written instrument the obligations of the Company under this
Agreement including this Section 2.2.7(b).

                             (c) Adjustment Due to Distribution.  Subject to the
restrictions herein contained, if at any time after the Initial Tranche Closing
Date but prior to either the Three Month Reset Date or the Six Month Reset Date,
as the case may be, the Company shall declare or make any distribution of its
assets (or rights to acquire its assets) or shares of its capital stock (other
than Common Stock) to holders of Common Stock as a partial liquidating dividend,
by way of return of capital or otherwise (including any dividend or distribution
to the Company's shareholders in cash or shares (or rights to acquire shares) of
capital stock of any other public or private company, including but not limited
to a subsidiary or spin-off of the Company (a "Distribution"), then the
Subscriber shall be entitled, upon issuance of either the Three Month Reset
Shares or Six Month Reset Shares, as the case may be, after the date of record
for determining shareholders entitled to such Distribution, to receive the
amount of such distribution (in kind) which would have been payable to the
Subscriber with respect to either the Three Month Reset Shares or Six Month
Reset Shares, as the case may be, had such Subscriber been the holder of such
shares of Common Stock on the record date for determination of shareholders
entitled to such Distribution.

sole and absolute discretion, elect to void all or any portion of the amount set
forth in the Advance Call Notice and elect not to exercise all or any portion of
any Call for Proceeds on the Call Date specified in such Advance Call Notice, if
the Market Price on such Call Date is less than eighty percent (80%) of the

                             (c) the number of shares of Common Stock that the

Notice by the Call Share Price with respect to such Call Date, subject to the
Call Limitations pursuant to Section 2.3.2 below; and

                             (d) the "Call Share Price" shall equal eighty five

per month, accruing daily, multiplied by such Call Dollar Amount, where "X"
equals one percent (1%) for the first month following the date in question, and

                to the Subscription Agreement and the Warrants;

        (d)     as of the Closing there have been no material adverse changes in
                the Company's business prospects or financial condition (defined

        (f)     the Company shall have reserved for issuance a sufficient number
                of Common Shares for the purpose of enabling the Company to

                      2.3.5  Reset of Call Shares.  In the event that the 
Company makes a public announcement or press release during the ten (10) Trading
Days after any Call Date and the Closing Bid Price on the date that is ten (10)
Trading Days after such Call Date (the "Call Reset Price") is less than eighty
five percent (85%) of the Call Share Price on such Call Date, then the Company
shall issue to the Subscriber an additional number of shares of Common Stock
(the "Call Reset Shares") equal to the difference of (a) the quotient of (i) the
Call Dollar Amount on such Call Date, divided by (ii) the Call Reset Price,
minus (b) the number of Call Shares on such Call Date. On or before the third

               2.4    Warrants.

                      2.4.1  Warrants upon Issuance of Common Stock.  On the 
Initial Tranche Closing Date and each Call Closing Date, the Company shall issue
a Warrant to the Subscriber to purchase a number of shares of Common Stock equal
to ten percent (10%) of the number of Common Shares issued to the Subscriber in
the applicable Closing. In the event that the Closing Bid Price on the date that
is ten (10) Trading Days after any Call Date is less than eighty five percent
(85%) of the Call Share Price on such Call Date, then the Company shall issue to
the Subscriber an additional Warrant to purchase a number of shares of Common
Stock equal to the difference of (i) ten percent (10%) of the number of Common
Shares that would have been issued to the Subscriber if the applicable Call Date
had occurred ten (10) Trading Days after the applicable Call Closing Date, minus
(ii) the number of shares of Common Stock that may be purchased by Subscriber
pursuant to 



                                      -24-
   21

the Warrant issued as a result of such original Call Date. The Warrant shall be
immediately exercisable at the Share Price (either the Initial Tranche Share
Price or the Call Share Price, as the case may be) of the Common Shares in the
applicable Closing, and shall have a term beginning on the date of issuance and
ending on December 31, 2004. The Warrant Shares shall be registered for resale
pursuant to the Registration Rights Agreement.

                      2.4.2  Commitment Warrants.  On the anniversary date of 
the Initial Tranche Closing Date and the two (2) succeeding anniversary dates
thereafter (each date a "Commitment Anniversary Date"), the Company shall issue
a Warrant to the Subscriber to purchase a number of shares of Common Stock equal
to ten percent (10%) of the quotient of (i) a dollar amount equal to the
difference of (a) the Minimum Commitment Amount, minus (b) the aggregate amount
of Common Stock sold to the Subscriber during all years preceding such
Commitment Anniversary Date, divided by (ii) the Market Price of the Common
Stock on such Commitment Anniversary Date. The Warrant shall be immediately
exercisable at the Market Price on such Commitment Anniversary Date and shall
have a term beginning on the date of issuance and ending on December 31, 2004.
The "Minimum Commitment Amount" shall equal $6,666,666.66 for the first year,
$13,333,333.32 for the second year and the Maximum Offering Amount for the third
year. The Warrant Shares shall be registered for resale pursuant to the
Registration Rights Agreement.

                      2.4.3 Issuance of Commitment Warrants upon Reorganization,
Consolidation, Merger, Ect. In case of any reorganization of the Company after
the Initial Tranche Closing Date, or in case, after such date, the Company shall
transfer all or substantially all of its properties or assets to or consolidate
with or merge into any other public or private company, including but not
limited to a subsidiary or spin-off of the Company, by way of return of capital
or otherwise (including any dividend or distribution to the Company's
shareholders in cash or shares (or rights to acquire shares) of capital stock of
any other public or private company, then in such case the Subscriber shall be
entitled to receive on the Trading Day prior to the date of consummation of such
reorganization, conveyance, consolidation or merger (the "Consummation Date"),
in lieu of any Warrants pursuant to Section 2.4.2, a warrant to purchase a
number of shares of Common Stock equal to ten percent (10%) of the quotient of
(i) a dollar amount equal to the difference of (a) the Maximum Offering Amount,
minus (b) the aggregate amount of Common Stock sold to the Subscriber pursuant
to this Agreement during all years preceding such Consummation Date, divided by
(ii) the Market Price of the Common Stock on the Trading Day (the "Valuation
Date") immediately prior to the date of the public announcement by the Company
of such reorganization, conveyance, consolidation or merger. Such warrant shall
be immediately exercisable at the Market Price on the Valuation Date and shall
entitle the Subscriber to receive, upon payment of the exercise price, in lieu
of the Common Stock issuable upon such exercise, the cash, securities or other
property to which the Subscriber would have been entitled upon such Consummation
Date if the Subscriber had so exercised such warrant immediately prior thereto.

               2.5 Subscriber's Right to Defer Receipt. If at any time the
Subscriber would have the right to receive shares of Common Stock from the
Company, including, without limitation, by reason of Section 2.2.2 (Three Month
Reset Shares and Six Month Reset Shares), Section 2.3 (Call for Proceeds) or
Section 2.3.5 (Reset of Call Shares), and/or the right to receive a Warrant or
Warrants by reason of Section 2.4 hereof, and as a result of receiving such
additional shares of Common Stock or such Warrants the Subscriber would be
deemed to be, after taking into account Common Shares previously acquired from
the Company, Warrant Shares deemed to be beneficially owned pursuant to
ownership of the Warrants, and any other shares of Common Stock of the Company
deemed to be beneficially 



                                      -25-
   22

owned by the Subscriber, the beneficial owner (within the meaning of Section
13(d) of the Exchange Act) of 9.9% of the Common Stock of the Company, the
Subscriber may elect to defer receipt of all or any portion of such Common
Shares from the Company and/or defer receipt of all or any portion of such
Warrant or Warrants, by sending a notice to the Company of such election. Such
election shall not affect the Subscriber's obligation to pay for Call Shares, as
if such election had not been made, nor shall it affect (other than by way of
deferral, as set forth herein) the Subscriber's absolute and unconditional right
to receive the shares of Common Stock and/or Warrants to which it was otherwise
entitled. In the event the Subscriber makes such election, (i) it may waive such
election, in whole or in part, at any time effective on sixty one (61) days'
prior notice to the Company and (ii) may waive it effective immediately upon
notice to the Company in the event of the announcement by the Company or any
third party of a Major Transaction. The Company shall deliver the shares and/or
Warrants to which the Subscriber is entitled on the effective date of the waiver
in the case of clause (i) above, and within three (3) Trading Days of the date
of the waiver notice in the case of a waiver pursuant to clause (ii) above.

        3. Representations, Warranties and Covenants of Subscriber. Subscriber
hereby represents and warrants to and agrees with the Company as follows:

               3.1 Accredited Investor. Subscriber is an accredited investor, as

               3.2 Investment Experience; Access to Information; Independent 
Investigation.

                      3.2.1 Access to Information. Subscriber or Subscriber's
professional advisor has been granted the opportunity to ask questions of and
receive answers from representatives of the Company, its officers, directors,
employees and agents concerning the terms and conditions of this Offering, the
Company and its business and prospects, and to obtain any additional information
which Subscriber or Subscriber's professional advisor deems necessary to verify
the accuracy and completeness of the information received.

                      3.2.2  Reliance on Own Advisors.  Subscriber has relied 
completely on the advice of, or has consulted with, Subscriber's own personal
tax, investment, legal or other advisors and has not relied on the Company or
any of its affiliates, officers, directors, attorneys, accountants or any
affiliates of any thereof and each other person, if any, who controls any of the
foregoing, within the meaning of Section 15 of the Act for any tax or legal
advice (other than reliance on information in the Disclosure Documents as
defined in Section 3.2.4 below and on the Opinion of Counsel). The foregoing,
however, does not limit or modify Subscriber's right to rely upon covenants,
representations and warranties of the Company in this Agreement.

                      3.2.3  Capability to Evaluate.  Subscriber has such 
knowledge and experience in financial and business matters so as to enable such

investment, which are substantial, including without limitation those set forth
in the Disclosure Documents (as defined in Section 3.2.4 below).



                                      -26-
   23

                      3.2.4  Disclosure Documents.  Subscriber, in making 
Subscriber's investment decision to subscribe for the Securities hereunder,
represents that (a) Subscriber has received and had an opportunity to review (i)
the Company's Annual Report on Form 10-K/A for the year ended April 30, 1997
(ii) the Company's quarterly report on Form 10-Q/A for the quarter ended January
31, 1998, (iii) the Risk Factors, attached as Exhibit J, (the "Risk Factors")
(iv) the Capitalization Schedule, attached as Exhibit K, (the "Capitalization
Schedule") and (v) the Use of Proceeds Schedule, attached as Exhibit L, (the
"Use of Proceeds Schedule"); (b) Subscriber has read, reviewed, and relied
solely on the documents described in (a) above, the Company's representations
and warranties and other information in this Agreement, including the exhibits,
documents prepared by the Company regarding the Swiss Transaction and the
Business Product Overview which has been specifically provided to Subscriber in
connection with this Offering (the documents described in this Section 3.2.4 (a)
and (b) are collectively referred to as the "Disclosure Documents"), and an
independent investigation made by Subscriber and Subscriber's representatives,
if any; (c) Subscriber has, prior to the date of this Agreement, been given an
opportunity to review material contracts and documents of the Company which have
been filed as exhibits to the Company's filings under the Act and the Securities
Exchange Act of 1934, as amended (the "Exchange Act") and has had an opportunity
to ask questions of and receive answers from the Company's officers and
directors; and (d) is not relying on any oral representation of the Company or
any other person, nor any written representation or assurance from the Company
other than those contained in the Disclosure Documents or incorporated herein or
therein. The foregoing, however, does not limit or modify Subscriber's right to
rely upon covenants, representations and warranties of the Company in Sections 5
and 6 of this Agreement. Subscriber acknowledges and agrees that the Company has
no responsibility for, does not ratify, and is under no responsibility
whatsoever to comment upon or correct any reports, analyses or other comments
made about the Company by any third parties, including, but not limited to,
analysts' research reports or comments (collectively, "Third Party Reports"),
and Subscriber has not relied upon any Third Party Reports, including any
provided by the Placement Agent, in making the decision to invest.

                      3.2.5  Investment Experience; Fend for Self.  Subscriber
has substantial experience in investing in securities and he, she or it has made
investments in securities other than those of the Company. Subscriber
acknowledges that Subscriber is able to fend for Subscriber's self in the
transaction contemplated by this Agreement, that Subscriber has the ability to
bear the economic risk of Subscriber's investment pursuant to this Agreement and
that Subscriber is an "Accredited Investor" by virtue of the fact that
Subscriber meets the investor qualification standards set forth in Section 3.1
above. Subscriber has not been organized for the purpose of investing in
securities of the Company, although such investment is consistent with
Subscriber's purposes.

               3.3    Exempt Offering Under Regulation D.

                      3.3.1  Investment; No Distribution.  Subscriber is 
acquiring the Securities to be issued and sold hereunder for his, her or its own
account (or a trust account if such Subscriber is a trustee) for investment and
not as a nominee and not with a present view to the distribution thereof.
Subscriber is aware that there are legal and practical limits on Subscriber's
ability to sell or dispose of the Securities and, therefore, that Subscriber may
be required to bear the economic risk of the investment for an indefinite period
of time, has adequate means of providing for Subscriber's current needs and
possible personal contingencies and could afford a complete loss of such
investment. Subscriber's commitment to illiquid investments is reasonable in
relation to Subscriber's net worth. 



                                      -27-
   24

By making the representations in this Section 3.3.1, the Subscriber does not
agree to hold the Securities for any minimum or other specific term and reserves
the right to dispose of the Securities at any time in accordance with or
pursuant to a registration statement or an exemption from registration under the
Act, except as otherwise limited or required by this Agreement, and the
Registration Rights Agreement.

                      3.3.2  No General Solicitation.  The Securities were not
offered to Subscriber through, and Subscriber is not aware of, any form of
general solicitation or general advertising, including, without limitation, (i)
any advertisement, article, notice or other communication published in any
newspaper, magazine or similar media or broadcast over television or radio, and
(ii) any seminar or meeting whose attendees have been invited by any general
solicitation or general advertising.

                      3.3.3  Restricted Securities.  Subscriber understands that
the Common Stock issued at the Initial Tranche Closing, the Common Stock issued
at each Call Closing will be, and the Warrant Shares will be, characterized as
"restricted securities" under the federal securities laws inasmuch as they are
being acquired from the Company in a transaction exempt from the registration
requirements of the federal securities laws and that under such laws and
applicable regulations such securities may not be transferred or resold without
registration under the Act or pursuant to an exemption therefrom. In this
connection, Subscriber represents that Subscriber is familiar with Rule 144
under the Act, as presently in effect, and understands the resale limitations
imposed thereby and by the Act.

                      3.3.4  Disposition.  Without in any way limiting the 
representations set forth above, Subscriber further agrees not to sell,
transfer, assign, pledge (except for any bona fide pledge arrangement to the
extent that such pledge does not require registration under the Act or unless an
exemption from such registration is available) and provided further that if such
pledge is realized upon, any transfer to the pledgee shall comply with the
requirements set forth herein), or otherwise dispose of all or any portion of
the Securities unless and until:

   26

Securities are being offered and sold in reliance on specific exemptions from
the registration requirements of federal and state law and that the
representations, warranties, agreements, acknowledgments and understandings set

applicability of such exemptions and the suitability of Subscriber to acquire
such Securities.

               4.7 Legends. It is understood that the certificates evidencing
the Common Stock delivered on the Initial Tranche Closing Date, the Warrants,
and the Warrant Shares, subject to legend removal under the terms of Section 6.9
below, shall bear the following legend (the "Legend"):

               "The securities represented hereby have not been registered under
               the Securities Act of 1933, as amended, or applicable state
               securities laws, nor the securities laws of any other
               jurisdiction. They may not be sold or transferred in the absence
               of an effective registration statement under those securities
               laws or pursuant to an exemption therefrom."

        5. Representations and Warranties of the Company. The Company hereby
makes the following representations and warranties to Subscriber (which shall be
true at the signing of this Agreement, as of the Initial Tranche Closing and
each Call Closing, and as of any such later date as contemplated hereunder) and
agrees with Subscriber that:

               5.1 Organization, Good Standing, and Qualification. The Company
is a corporation duly organized, validly existing and in good standing under the
laws of the State of Delaware USA and has all requisite corporate power and
authority to carry on its business as now 



                                      -30-
   27

conducted and as proposed to be conducted. The Company is duly qualified to
transact business and is in good standing in each jurisdiction in which the
failure to so qualify would have a material adverse effect on the business or
properties of the Company and its subsidiaries taken as a whole. The Company is
not the subject of any pending, threatened or, to its knowledge, contemplated
investigation or administrative or legal proceeding (a "Proceeding") by the
Internal Revenue Service, the taxing authorities of any state or local
jurisdiction, or the Securities and Exchange Commission ("SEC"), The National
Association of Securities Dealer, Inc., The Nasdaq Stock Market, Inc. or any
state securities commission, or any other governmental entity, which have not
been disclosed in the Disclosure Documents. None of the disclosed Proceedings,
if any, will have a material adverse effect upon the Company or the market for
the Common Stock. The Company has one subsidiary, Peregrine Pharmaceuticals,
Inc..

               5.2 Corporate Condition. The Company's condition is, in all
material respects, as described in the Disclosure Documents, except for changes
in the ordinary course of business and normal year-end adjustments that are not,
in the aggregate, materially adverse to the Company. Except for continuing
losses, there have been no material adverse changes to the Company's business,
financial condition, or prospects since the date of such Disclosure Documents.
The financial statements as contained in the 10-K/A and 10-Q/A have been
prepared in accordance with generally accepted accounting principles,
consistently applied (except as otherwise permitted by Regulation S-X of the
Exchange Act), and fairly present the financial condition of the Company as of
the dates of the balance sheets included therein and the consolidated results of
its operations and cash flows for the periods then ended. Without limiting the
foregoing, there are no material liabilities, contingent or actual, that are not
disclosed in the Disclosure Documents (other than liabilities incurred by the
Company in the ordinary course of its business, consistent with its past
practice, after the period covered by the Disclosure Documents). The Company has
paid all material taxes, which are due, except for taxes, which it reasonably
disputes. There is no material claim, litigation, or administrative proceeding
pending, or, to the best of the Company's knowledge, threatened against the
Company, except as disclosed in the Disclosure Documents. This Agreement and the
Disclosure Documents do not contain any untrue statement of a material fact and
do not omit to state any material fact required to be stated therein or herein
necessary to make the statements contained therein or herein not misleading in
the light of the circumstances under which they were made. No event or
circumstance exists relating to the Company which under applicable law, requires
public disclosure but which has not been so publicly announced or disclosed.

               5.3 Authorization. All corporate action on the part of the
Company by its officers, directors and shareholders necessary for the
authorization, execution and delivery of this Agreement, the performance of all
obligations of the Company hereunder and the authorization, issuance and
delivery of the Common Stock being sold hereunder and the issuance (and/or the
reservation for issuance) of the Warrants and the Warrant Shares have been
taken, and this Agreement, the Escrow Agreement and the Registration Rights
Agreement constitute valid and legally binding obligations of the Company,
enforceable in accordance with their terms, except insofar as the enforceability
may be limited by applicable bankruptcy, insolvency, reorganization, or other
similar laws affecting creditors' rights generally or by principles governing
the availability of equitable remedies. The Company has obtained all consents
and approvals required for it to execute, deliver and perform each agreement
referenced in the previous sentence.

               5.4 Valid Issuance of Common Stock. The Common Stock and the

for the consideration expressed herein, will be validly issued, fully paid and
nonassessable and, based in part upon the representations of Subscriber in this
Agreement, will be issued in compliance with all applicable U.S. federal and
state securities laws. The Warrant Shares, when issued in accordance with the
terms of the Warrants, shall be duly and validly issued and outstanding, fully
paid and nonassessable, and based in part on the representations and warranties
of Subscriber, will be issued in compliance with all applicable U.S. federal and
state securities laws. The Common Stock, the Warrants and the Warrant Shares

the Initial Tranche Closing and reserved for issuance upon exercise of the
Warrants.

               5.5 Compliance with Other Instruments. The Company is not in
violation or default of any provisions of its Certificate of Incorporation or
Bylaws each as amended, and in effect on and as of the date of the Agreement or
of any material provision of any material instrument or material contract to
which it is a party or by which it is bound or of any provision of any federal
or state judgment, writ, decree, order, statute, rule or governmental regulation
applicable to the Company, which would have a material adverse effect on the
Company's business or prospects, or on the performance of its obligations under
this Agreement or the Registration Rights Agreement. The execution, delivery and
performance of this Agreement and the other agreements entered into in
conjunction with the Offering and the consummation of the transactions
contemplated hereby and thereby will not (a) result in any such violation or be
in conflict with or constitute, with or without the passage of time and giving
of notice, either a default under any such provision, instrument or contract or
an event which results in the creation of any lien, charge or encumbrance upon
any assets of the Company, which would have a material adverse effect on the
Company's business or prospects, or on the performance of its obligations under
this Agreement, the Registration Rights Agreement, (b) violate the Company's
Certificate of Incorporation or By-Laws or (c) violate any statute, rule or
governmental regulation applicable to the Company which violation would have a
material adverse effect on the Company's business or prospects.

               5.6 Reporting Company. The Company is subject to the reporting
requirements of the Exchange Act, has a class of securities registered under
Section 12 of the Exchange Act, and has filed all reports required by the
Exchange Act since the date the Company first became subject to such reporting
obligations. The Company undertakes to furnish Subscriber with copies of such

this Offering and thereafter, to make such reports available, for the full term
of this Agreement, including any extensions thereof, and for as long as
Subscriber holds the Securities. The Common Stock is duly listed on the Nasdaq
Small Cap Market. The Company is not in violation of the listing requirements of
the Nasdaq Small Cap Market and does not reasonably anticipate that the Common
Stock will be delisted by the Nasdaq Small Cap Market for the foreseeable
future. The Company has filed all reports required under the Exchange Act. The
Company has not furnished to the Subscriber any material nonpublic information
concerning the Company.

               5.7 Capitalization. The capitalization of the Company as of June

any outstanding Series C Preferred Stock, exercise of any outstanding warrants
and/or exercise of any outstanding stock options, after taking into account the
offering of the Securities contemplated by this Agreement and all other share



                                      -32-
   29

issuances occurring prior to this Offering, will be, as set forth in the

triggered by the issuance of the Securities. Except as disclosed in the
Capitalization Schedule, as of the date of this Agreement, (i) there are no
outstanding options, warrants, scrip, rights to subscribe for, calls or
commitments of any character whatsoever relating to, or securities or rights
convertible into or exercisable or exchangeable for, any shares of capital stock
of the Company or any of its subsidiaries, or arrangements by which the Company
or any of its subsidiaries is or may become bound to issue additional shares of
capital stock of the Company or any of its subsidiaries, and (ii) there are no
agreements or arrangements under which the Company or any of its subsidiaries is
obligated to register the sale of any of its or their securities under the Act
(except the Registration Rights Agreement, and registration rights relating to
the Class C Preferred Stock penalties, the BTD Warrants, the Rudolph and Sletton
Warrants and the 1998 private placement shares and warrants).

               5.8 Intellectual Property. The Company has valid, unrestricted
and exclusive ownership of or rights to use the patents, trademarks, trademark
registrations, trade names, copyrights, know-how, technology and other
intellectual property necessary to the conduct of its business. Exhibit M lists
all patents, trademarks, trademark registrations, trade names and copyrights of
the Company. The Company has granted such licenses or has assigned or otherwise
transferred a portion of (or all of) such valid, unrestricted and exclusive
patents, trademarks, trademark registrations, trade names, copyrights, know-how,
technology and other intellectual property necessary to the conduct of its
business as set forth in Exhibit M. The Company has been granted licenses,
know-how, technology and/or other intellectual property necessary to the conduct
of its business as set forth in Exhibit M. To the best of the Company's
knowledge after due inquiry, the Company is not infringing on the intellectual
property rights of any third party, nor is any third party infringing on the
Company's intellectual property rights. There are no restrictions in any
agreements, licenses, franchises, or other instruments that preclude the Company
from engaging in its business as presently conducted.

               5.9 Use of Proceeds. As of the date hereof, the Company expects
to use the proceeds from this Offering (less fees and expenses) for the purposes
and in the approximate amounts set forth on the Use of Proceeds Schedule set
forth as Exhibit L hereto. These purposes and amounts are estimates and are
subject to change without notice to any Subscriber.

               5.10 No Rights of Participation. No person or entity, including,
but not limited to, current or former shareholders of the Company, underwriters,
brokers, agents or other third parties, has any right of first refusal,
preemptive right, right of participation, or any similar right to participate in
the financing contemplated by this Agreement which has not been waived.

               5.11 Company Acknowledgment. The Company hereby acknowledges that
Subscriber may elect to hold the Securities for various periods of time, as
permitted by the terms of this Agreement, the Warrants, and other agreements
contemplated hereby, and the Company further acknowledges that Subscriber and
the Placement Agent have made no representations or warranties, either written
or oral, as to how long the Securities will be held by Subscriber or regarding
Subscriber's trading history or investment strategies.



                                      -33-
   30

               5.12 Termination Date of Offering. In no event shall the Initial
Tranche Closing Date occur later than three (3) Business Days after the Initial
Tranche Subscription Date. If the Initial Tranche Closing does not occur within
three (3) Business Days of the Initial Tranche Subscription Date, then either
party may terminate this Agreement without affecting any liability either party
may have as a result of any breach of this Agreement prior to such termination.

               5.13 Underwriter's Fees and Rights of First Refusal. The Company
is not obligated to pay in excess of two hundred thousand dollars ($200,000)
compensation or other fees, costs or related expenditures in cash or securities
to any underwriter, broker, agent or other representative other than the
Placement Agent in connection with this Offering.

               5.14 Availability of Suitable Form for Registration. The Company
is currently eligible and agrees to maintain its eligibility to register the
resale of its Common Stock on a registration statement on a suitable form under
the Act.

               5.15 No Integrated Offering. Neither the Company, nor any of its
affiliates, nor any person acting on its or their behalf, has directly or
indirectly made any offers or sales of any of the Company's securities or
solicited any offers to buy any security under circumstances that would prevent
the parties hereto from consummating the transactions contemplated hereby
pursuant to an exemption from registration under the Act pursuant to the
provisions of Regulation D or would require the issuance of any other securities
to be integrated with this Offering under the Rules of Nasdaq. The Company has
not engaged in any form of general solicitation or advertising in connection
with the offering of the Common Stock or the Warrants.

               5.16 Acknowledgment of Dilution. The number of Three Month Reset
Shares and Six Month Reset Shares that the Company may be obligated to issue on
either the Three Month Reset Date or the Six Month Reset Date may increase
substantially in certain circumstances, including the circumstance in which the
trading price of the Common Stock declines. Such shares, alone or in combination
with the Initial Tranche Shares, may represent a substantial portion of the
Company's capitalization and may have an adverse impact on the market for the
Common Stock. The Company's executive officers and directors have studied and
fully understand the nature of this Agreement and the Securities being sold
hereunder and recognize that they have a potential dilutive effect. The board of
directors of the Company has concluded in its good faith business judgment that
such issuance is in the best interests of the Company.

               5.17 Foreign Corrupt Practices. Neither the Company, nor any of
its subsidiaries, nor any director, officer, agent, employee or other person
acting on behalf of the Company or any subsidiary has, in the course of its
actions for, or on behalf of, the Company, used any corporate funds for any
unlawful contribution, gift, entertainment or other unlawful expenses relating
to political activity; made any direct or indirect unlawful payment to any
foreign or domestic government official or employee from corporate funds;
violated or is in violation of any provision of the U.S. Foreign Corrupt
Practices Act of 1977, as amended; or made any bribe, rebate, payoff, influence
payment, kickback or other unlawful payment to any foreign or domestic
government official or employee.

               5.18 Key Employees. Each Key Employee (as defined below) is
currently serving the Company in the capacity disclosed in Exhibit N. No Key
Employee, to the best knowledge of the 



                                      -34-
   31

Company and its subsidiaries, is, or is now expected to be, in violation of any
material term of any employment contract, confidentiality, disclosure or
proprietary information agreement, non-competition agreement, or any other
contract or agreement or any restrictive covenant, and the continued employment
of each Key Employee does not subject the Company or any of its subsidiaries to
any liability with respect to any of the foregoing matters. No Key Employee has,
to the best knowledge of the Company and its subsidiaries, any intention to
terminate his employment with, or services to, the Company or any of its
subsidiaries. "Key Employee" means Larry Bymaster, President and Chief Executive
Officer.

               5.19 Representations Correct. The foregoing representations,
warranties and agreements are true, correct and complete in all material
respects, and shall survive the Initial Tranche Closing and any Call Closing and
the issuance of the shares of Common Stock thereby.

               5.20 Tax Status. The Company has made or filed all federal and
state income and all other tax returns, reports and declarations required by any
jurisdiction to which it is subject (unless and only to the extent that the
Company has set aside on its books provisions reasonably adequate for the
payment of all unpaid and unreported taxes) and has paid all taxes and other
governmental assessments and charges that are material in amount, shown or
determined to be due on such returns, reports and declarations, except those
being contested in good faith and as set aside on its books provision reasonably
adequate for the payment of all taxes for periods subsequent to the periods to
which such returns, reports or declarations apply. There are no unpaid taxes in
any material amount claimed to be due by the taxing authority of any
jurisdiction, and the officers of the Company know of no basis for any such
claim.

               5.21 Transactions With Affiliates. Except as set forth in the
Disclosure Documents, none of the officers, directors, or employees of the
Company is presently a party to any transaction with the Company (other than for
services as employees, officers and directors), including any contract,
agreement or other arrangement providing for the furnishing of services to or
by, providing for rental of real or personal property to or from, or otherwise
requiring payments to or from any officer, director or such employee or, to the
knowledge of the Company, any corporation, partnership, trust or other entity in
which any officer, director, or any such employee has a substantial interest or
is an officer, director, trustee or partner.

               5.22 Application of Takeover Protections. The Company and its
board of directors have taken all necessary action, if any, in order to render
inapplicable any control share acquisition, business combination or other
similar anti-takeover provision under Delaware law which is or could become
applicable to the Subscriber as a result of the transactions contemplated by
this Agreement, including, without limitation, the issuance of the Common Stock,
any exercise of the Warrants and ownership of the Common Shares and Warrant
Shares. The Company has not adopted and will not adopt any "poison pill"
provision that will be applicable to Subscriber as a result of transactions
contemplated by this Agreement.

indirectly, made any agreements with the Subscriber, or any Other Subscribers,

Subscription Agreement, respectively, or in exhibits hereto or thereto.

million dollars ($4,000,000) to fund the buyout of certain distribution rights
from Biotechnology Development Ltd. (the "BTD Buyout").

and shall pay all its taxes when due except for taxes which the Company

convey or otherwise dispose of any of its material assets to any Subsidiary
except for a cash or cash equivalent consideration and for a proper business
purpose or (ii) ) transfer, sell, convey or otherwise dispose of any of its
material assets to any Affiliate, as defined below, during the Term of this
Agreement. For purposes hereof, "Affiliate" shall mean any officer of the
Company, director of the Company or owner of twenty percent (20%) or more of the
Common Stock or other securities of the Company.

               6.6    Capital Raising Limitations; Rights of First Refusal.

                      6.6.1  Capital Raising Limitations.  During the Term of 
this Agreement, the Company shall not issue or sell, or agree to issue or sell,
for cash in private capital raising transactions (the following to be
collectively referred to herein as, the "Variable Deals"), (a) any debt or
equity securities which are convertible into, exercisable or exchangeable for,
or carry the right to receive additional shares of Common Stock either (i) at
any conversion, exercise or exchange rate or other price that is based upon
and/or varies with the trading prices of or quotations for Common Stock at any

                                      -36-

transaction, including the terms and conditions thereof, and providing the
Subscriber and its affiliates an option during the ten (10) day period following
delivery of such notice to purchase securities being offered in such transaction
on the same terms as contemplated by such transaction. The maximum amount of
securities which a Subscriber is entitled to purchase (the "Participation
Amount") in such transaction shall be a number obtained by multiplying the
aggregate amount of securities being offered in such transaction by twenty
percent (20%); provided, however, that the lead investor or the placement agent
of such transaction may elect to purchase the Subscriber's right to participant
in such transaction by paying Subscriber a dollar amount equal to the greater of

issuances of securities in connection with a merger, consolidation, acquisition
or sale of assets, or in connection with any strategic partnership or joint
venture (the primary purpose of which is not to raise equity capital), or in

               6.9 Removal of Legend. The Legend shall be removed and the
Company shall issue a certificate without such Legend to the holder of any
Security upon which it is stamped, and a certificate for a security shall be
originally issued without the Legend, if, (a) the sale of such Security is
registered under the Act, or (b) such holder provides the Company with an
opinion of counsel, in form, substance and scope customary for opinions of
counsel in comparable transactions (the reasonable cost of which shall be borne
by the Company), to the effect that a public sale or transfer of such Security
may be made without registration under the Act, or (c) such holder provides the
Company with reasonable assurances that such Security can be sold pursuant to
Rule 144. Each Subscriber agrees to sell all Securities, including those
represented by a certificate(s) from which the Legend has been removed, or which
were originally issued without the Legend, pursuant to an effective registration
statement and to deliver a prospectus in connection with such sale or in
compliance with an exemption from the registration requirements of the Act.

               6.10 Listing. Subject to the remainder of this Section 6.10, the
Company shall ensure that its shares of Common Stock (including all Warrant
Shares) are listed and available for trading on the Nasdaq Small Cap Market
("NASDAQ"). Thereafter, the Company shall (i) use its best efforts to continue
the listing and trading of its Common Stock on the NASDAQ, or on the Nasdaq
National Market System ("NMS"), the New York Stock Exchange ("NYSE"), or the
American Stock Exchange ("AMEX") or any other national exchange or
over-the-counter market system; and (ii) comply in all material respects with
the Company's reporting, filing and other obligations under the By-Laws or rules
of the National Association of Securities Dealers ("NASD") and such exchanges,
as applicable.

               6.11 The Company's Instructions to Transfer Agent. The Company
will instruct the Transfer Agent of the Common Stock to issue certificates,
registered in the name of each Subscriber or its nominee, for the Common Shares
and Warrant Shares in such amounts as specified from time to time by the Company
upon the Initial Tranche Closing, any exercise by the Company of a Call for
Proceeds and exercise of the Warrants. Such certificates shall bear a Legend
only to the extent permitted by Section 6.9 hereof and the Company shall use its
reasonable best efforts to cause the Transfer Agent to issue such certificates
without a Legend, except for the Initial Tranche Shares until such Initial
Tranche Shares are registered for resale under the Act. Nothing in this Section
shall affect in any way each Subscriber's obligations and agreement set forth in
Sections 3.3.3 or 3.3.4 hereof to resell the Securities pursuant to an effective
registration statement and to deliver a prospectus in connection with such sale
or in compliance with an exemption from the registration requirements of
applicable securities laws. If (a) a Subscriber provides the Company with an
opinion of counsel, which opinion of counsel shall be in form, substance and
scope customary for opinions of counsel in comparable transactions (the
reasonable cost of which shall be borne by the Company), to the effect that the
Securities to be sold or transferred may be sold or transferred pursuant to an
exemption from registration or (b) a Subscriber transfers Securities to an
affiliate which is an accredited investor pursuant to Rule 144, the Company
shall permit the transfer, and, in the case of Common Shares and Warrant Shares,
promptly instruct its transfer agent to issue one or more certificates in such
name and in such denomination as specified by such Subscriber. The Company
acknowledges that a breach by it of its obligations hereunder will cause
irreparable harm to a Subscriber by vitiating the intent and purpose of the
transaction contemplated hereby. Accordingly, the Company acknowledges that the
remedy at law for a breach of its obligations under this Section 6.11 will be
inadequate and agrees, in the event of a breach or threatened breach by the
Company of the provisions of this Section 6.11, that a Subscriber shall be
entitled, in addition to all 



                                      -38-
   35

other available remedies, to an injunction restraining any breach and requiring
immediate issuance and transfer, without the necessity of showing economic loss
and without any bond or other security being required.

               6.12 Shareholder 20% Approval. The Company shall, at its next
annual shareholder meeting, to be held no later than October 31, 1998, use its
best efforts to obtain approval of its shareholders to authorize (i) the
issuance of the full number of shares of Common Stock which would be issuable
pursuant to this Agreement but for the Cap Amount and eliminate any prohibitions
under applicable law or the rules or regulations of any stock exchange,
interdealer quotation system or other self-regulatory organization with
jurisdiction over the Company or any of its securities with respect to the
Company's ability to issue shares of Common Stock in excess of the Cap Amount
(such approvals being the "Shareholder 20% Approval").

               6.13 Press Release. The Company agrees that the Subscriber shall
have the right to review and comment upon any press release issued by the
Company in connection with the Offering which approval shall not be unreasonably
withheld by Subscriber.

        7.     Subscriber Covenant/Miscellaneous

               7.1 Representations and Warranties Survive the Closing;
Severability. Subscriber's and the Company's representations and warranties
shall survive the Initial Tranche Closing and any Call Closing contemplated by
this Agreement notwithstanding any due diligence investigation made by or on
behalf of the party seeking to rely thereon. In the event that any provision of
this Agreement becomes or is declared by a court of competent jurisdiction to be
illegal, unenforceable or void, this Agreement shall continue in full force and
effect without said provision; provided that no such severability shall be
effective if it materially changes the economic benefit of this Agreement to any
party.

               7.2 Successors and Assigns. The terms and conditions of this
Agreement shall inure to the benefit of and be binding upon the respective
successors and assigns of the parties. Nothing in this Agreement, express or
implied, is intended to confer upon any party other than the parties hereto or
their respective successors and assigns any rights, remedies, obligations, or
liabilities under or by reason of this Agreement, except as expressly provided
in this Agreement. Subscriber may assign Subscriber's rights hereunder, in
connection with any private sale of the Common Stock of such Subscriber, so long
as, as a condition precedent to such transfer, the transferee executes an
acknowledgment agreeing to be bound by the applicable provisions of this
Agreement in a form acceptable to the Company and provides an original copy of
such acknowledgment to the Company.

               7.3 Execution in Counterparts Permitted. This Agreement may be
executed in any number of counterparts, each of which shall be enforceable
against the parties actually executing such counterparts, and all of which
together shall constitute one (1) instrument.

               7.4 Titles and Subtitles; Gender. The titles and subtitles used
in this Agreement are used for convenience only and are not to be considered in
construing or interpreting this Agreement. The use in this Agreement of a
masculine, feminine or neither pronoun shall be deemed to include a reference to
the others.

this Agreement shall be in writing and shall be deemed given when delivered
personally, or by facsimile or upon receipt if by overnight or two (2) day
courier, addressed to the parties at the addresses and/or facsimile telephone
number of the parties set forth at the end of this Agreement or such other
address as a party may request by notifying the other in writing; provided,
however, that in order for any notice to be effective as to the Subscriber such
notice shall be delivered and sent, as specified herein, to all the addresses
and facsimile telephone numbers of the Subscriber set forth at the end of this
Agreement or such other address and/or facsimile telephone number as Subscriber
may request in writing .

               7.6 Expenses. Except as set forth in the Registration Rights
Agreement, each of the Company and Subscriber shall pay all costs and expenses
that it respectively incurs, with respect to the negotiation, execution,
delivery and performance of this Agreement.

               7.7 Entire Agreement; Written Amendments Required. This
Agreement, including the Exhibits attached hereto, the Common Stock
certificates, the Warrants, the Registration Rights Agreement, the Escrow
Agreement, and the other documents delivered pursuant hereto constitute the full
and entire understanding and agreement between the parties with regard to the
subjects hereof and thereof, and no party shall be liable or bound to any other
party in any manner by any warranties, representations or covenants except as
specifically set forth herein or therein. Except as expressly provided herein,
neither this Agreement nor any term hereof may be amended, waived, discharged or
terminated other than by a written instrument signed by the party against whom
enforcement of any such amendment, waiver, discharge or termination is sought.

               7.8 Arbitration. Any controversy or claim arising out of or
related to the Transaction Documents or the breach thereof, shall be settled by
binding arbitration in Wilmington, Delaware in accordance with the Expedited
Procedures (Rules 53-57) of the Commercial Arbitration Rules of the American
Arbitration Association ("AAA"). A proceeding shall be commenced upon written
demand by Company or any Subscriber to the other. The arbitrator(s) shall enter
a judgment by default against any party, which fails or refuses to appear in any
properly noticed arbitration proceeding. The proceeding shall be conducted by
one (1) arbitrator, unless the amount alleged to be in dispute exceeds two
hundred fifty thousand dollars ($250,000), in which case three (3) arbitrators
shall preside. The arbitrator(s) will be chosen by the parties from a list
provided by the AAA, and if they are unable to agree within ten (10) days, the
AAA shall select the arbitrator(s). The arbitrators must be experts in
securities law and financial transactions. The arbitrators shall assess costs
and expenses of the arbitration, including all attorneys' and experts' fees, as
the arbitrators believe is appropriate in light of the merits of the parties'
respective positions in the issues in dispute. Each party submits irrevocably to
the jurisdiction of any state court sitting in Wilmington, Delaware or to the
United States District Court sitting in Delaware for purposes of enforcement of
any discovery order, judgment or award in connection with such arbitration. The
award of the arbitrator(s) shall be final and binding upon the parties and may
be enforced in any court having jurisdiction. The arbitration shall be held in
such place as set by the arbitrator(s) in accordance with Rule 55.

               Although the parties, as expressed above, agree that all claims,
including claims that are equitable in nature, for example specific performance,
shall initially be prosecuted in the binding 



                                      -40-
   37

arbitration procedure outlined above, if the arbitration panel dismisses or
otherwise fails to entertain any or all of the equitable claims asserted by
reason of the fact that it lacks jurisdiction, power and/or authority to
consider such claims and/or direct the remedy requested, then, in only that
event, will the parties have the right to initiate litigation respecting such
equitable claims or remedies. The forum for such equitable relief shall be in
either a state or federal court sitting in Wilmington, Delaware. Each party
waives any right to a trial by jury, assuming such right exists in an equitable
proceeding, and irrevocably submits to the jurisdiction of said Delaware court.
Delaware law shall govern both the proceeding as well as the interpretation and
construction of the Transaction Documents and the transaction as a whole.

        8.     Subscription and Wiring Instructions; Irrevocability.

                (b)     Irrevocable Subscription. Subscriber hereby acknowledges
                        and agrees, subject to the provisions of any applicable
                        laws providing for the refund of subscription amounts
                        submitted by Subscriber, that this Agreement is
                        irrevocable and that Subscriber is not entitled to
                        cancel, terminate or revoke this Agreement or any other
                        agreements executed by such Subscriber and delivered
                        pursuant hereto, and that this Agreement and such other
                        agreements shall survive the death or disability of such
                        Subscriber and shall be binding 



                                      -41-
   38

                        upon and inure to the benefit of the parties and their
                        heirs, executors, administrators, successors, legal
                        representatives and assigns. If the Securities
                        subscribed for are to be owned by more than one person,
                        the obligations of all such owners under this Agreement
                        shall be joint and several, and the agreements,
                        representations, warranties and acknowledgments herein
                        contained shall be deemed to be made by and be binding
                        upon each such person and his heirs, executors,
                        administrators, successors, legal representatives and
                        assigns. Notwithstanding the foregoing, (i) if the
                        conditions to Closing are not satisfied or (ii) if the
                        Disclosure Documents are discovered prior to Closing to
                        contain statements which are materially inaccurate, or
                        omit statements of material fact, Subscriber may revoke
                        or cancel this Agreement.

                        (c) Company's Right to Reject Subscription. Subscriber
                        understands that this Agreement is not binding on the
                        Company until the Company accepts it. This Agreement
                        shall be accepted by the Company when the Company
                        countersigns this Agreement. Subscriber hereby confirms
                        that the Company has full right in its sole discretion
                        to accept or reject the subscription of Subscriber, in
                        whole or in part, provided that, if the Company decides
                        to reject such subscription, the Company must do so
                        promptly and in writing. In the case of rejection, the
                        Company will promptly return any rejected payments and
                        (if rejected in whole) copies of all executed
                        subscription documents (including without limitation
                        this Agreement) to Subscriber. In the event of
                        rejection, no interest will be payable by the Company to
                        Subscriber on any return of payment, provided however,
                        that any such interest accrued on such funds in the
                        Escrow Account shall be returned to the Subscriber by
                        the Escrow Agent.

               8.2 Acceptance of Subscription. Ownership of the number of
securities being purchased hereby will pass to Subscriber upon the Initial
Tranche Closing or any Call Closing.

               8.3    [Intentionally Omitted]

        9.     Indemnification.

               In consideration of the Subscriber's execution and delivery of
the Subscription Agreement, the Registration Rights Agreement, the Escrow
Agreement and the Warrants (the "Transaction Documents") and acquiring the
Securities thereunder and in addition to all of the Company's other obligations
under the Transaction Documents, the Company shall defend, protect, indemnify
and hold harmless Subscriber and the Placement Agent and all of their
stockholders, officers, directors, employees and direct or indirect investors
and any of the foregoing person's agents, members, partners or other
representatives (including, without limitation, those retained in 



                                      -42-
   39

connection with the transactions contemplated by this Agreement) (collectively,
the "Indemnitees") from and against any and all actions, causes of action,
suits, claims, losses, costs, penalties, fees, liabilities and damages, and
expenses in connection therewith (irrespective of whether any such Indemnitee is
a party to the action for which indemnification hereunder is sought), and
including reasonable attorney's fees and disbursements (the "Indemnified
Liabilities"), incurred by any Indemnitee as a result of, or arising out of, or
relating to (a) any misrepresentation or breach of any representation or
warranty made by the Company in the Transaction Documents or any other
certificate, instrument or documents contemplated hereby or thereby, (b) any
breach of any covenant, agreement or obligation of the Company contained in the
Transaction Documents or any other certificate, instrument or document
contemplated hereby or thereby, or (c) any cause of action, suit or claim,
derivative or otherwise, by any shareholder of the Company based on a breach or
alleged breach by the Company or any of its officers or directors of their
fiduciary or other obligations to the shareholders of the Company.

               To the extent that the foregoing undertaking by the Company may
be unenforceable for any reason, the Company shall make the maximum contribution
to the payment and satisfaction of each of the Indemnified Liabilities which it
would be required to make if such foregoing undertaking was enforceable which is
permissible under applicable law.

               Promptly after receipt by an Indemnified Party of notice of the
commencement of any action pursuant to which indemnification may be sought, such
Indemnified Party will, if a claim in respect thereof is to be made against the
other party (hereinafter "Indemnitor") under this Section 9, deliver to the
Indemnitor a written notice of the commencement thereof and the Indemnitor shall
have the right to participate in and to assume the defense thereof with counsel
reasonably selected by the Indemnitor, provided, however, that an Indemnified
Party shall have the right to retain its own counsel, with the reasonably
incurred fees and expenses of such counsel to be paid by the Indemnitor, if
representation of such Indemnified Party by the counsel retained by the
Indemnitor would be inappropriate due to actual or potential conflicts of
interest between such Indemnified Party and any other party represented by such
counsel in such proceeding. The failure to deliver 



                                      -43-
   40

written notice to the Indemnitor within a reasonable time of the commencement of
any such action, if prejudicial to the Indemnitor's ability to defend such
action, shall relieve the Indemnitor of any liability to the Indemnified Party
under this Section 9, but the omission to so deliver written notice to the
Indemnitor will not relieve it of any liability that it may have to any
Indemnified Party other than under this Section 9 to the extent it is
prejudicial.

               WHEREAS, pursuant to the terms of that certain Registration

        deliver to Subscribers an additional opinion letter at the time that the

   2

        NOW, THEREFORE, in consideration of the mutual promises,
representations, warranties, covenants and conditions set forth in Agreement and
for other good and valuable consideration, the receipt and sufficiency of which
is hereby acknowledged, the parties hereto agree as follows:

        1. Amendment of Section 6.11. The Company and Subscriber hereby agree
and amend Section 6.11 of the Subscription Agreement as follows:

        "Such certificates shall bear a Legend only to the extent permitted by
        Section 6.9 hereof and the Company shall use its best efforts to cause
        the Transfer Agent to issue such certificates without a Legend, except
        for the Initial Tranche Shares until such Initial Tranche Shares are
        registered for resale under the Act."

        2. Amendment of Section 6.8. The Company and Subscriber hereby agree
that Exhibit I of the Subscription Agreement shall be in the form attached
hereto as Exhibit I, and shall also contain language substantially in the form
and substance as follows:

        "In the course of the preparation of the Registration Statement, which
        involved, among other things, discussions and inquiries concerning the
        various legal matters and the review of certain corporate records,
        documents and proceedings, we participated in conferences with certain
        officers and other representatives of the Company during which the
        contents of the Registration Statement (including the documents
        incorporated therein by reference) were discussed, and we advised the
        Company as to the requirements of the Securities Act of 1933, as
        amended, and the applicable rules and regulations thereunder. During the
        course of the representation, nothing has come to our attention to cause
        us to have reason to believe that the Registration Statement (including
        the documents incorporated therein by reference) contains any untrue
        statement of a material fact, or omits to state therein a material fact
        required to be stated therein or necessary to make the statements
        therein not misleading."

        IN WITNESS WHEREOF, the undersigned have executed this Agreement as of
this ___ day of June, 1998.

than three (3) months, the Accrual Principal Amount shall thereafter be the
greater of (i) the Initial Accrual Principal Amount, or (ii) the Aggregate
Outstanding Share Price of all or any portion of Holder's Registrable Securities

Share Price at any given time shall be determined by aggregating the Share
Prices, as reset from time to time under the terms of the Subscription
Agreement, if applicable, of all shares of Registrable Securities then held by
Holder. For purposes of determining the Share Prices of Registrable Securities
held by Holder, "first in first out" accounting shall be used. For example, if
Holder has sold or otherwise disposed of any of its Registrable Securities, then
the first share sold or disposed of shall be deemed to be the first share that

               "Warrants" shall mean the Subscriber Warrants and the Placement
Agent Warrants collectively.

        14.    Required Registration.

               14.1 Registrable Securities. "Registrable Securities" shall mean
only those shares of the Common Stock of the Company together with any capital
stock issued in replacement of, in exchange for or otherwise in respect of such
Common Stock, that are: (i) issuable or issued to the Subscriber pursuant to the
Subscription Agreement or in this Agreement, (ii) issuable or issued upon
exercise of the Subscriber Warrants, (iii) issuable or issued to Swartz pursuant
to the Placement Agent Agreement, and (iv) issuable or issued upon exercise of
the Placement Agent Warrants; provided, however, that notwithstanding the above,
the following shall not be considered Registrable Securities:

                      (a) any Common Stock which would otherwise be deemed to be
Registrable Securities, if and to the extent that those shares of Common Stock
may be resold in a public transaction without volume limitations or other
material restrictions without registration under the Act, including without
limitation, pursuant to Rule 144 under the Act;

                      (b) any Registrable Securities resold in a public 
transaction; and

                      (c) any shares of Common Stock which have been sold in a
private transaction in which the transferor's rights under this Agreement are
not assigned.

               14.2 Filing of Initial Registration Statement. The Company shall,
by the Filing Date, file a registration statement ("Registration Statement") on
Form S-1 (or other suitable form, at the Company's discretion, but subject to
the reasonable approval of Subscribers), covering the resale of a number of
shares of Common Stock as Registrable Securities equal to at least Ten Million



                                       5
   6

(10,000,000) shares of Common Stock and shall cover, to the extent allowed by
applicable law, such indeterminate number of additional shares of Common Stock
that may be issued or become issuable as Registrable Securities by the Company
pursuant to the Subscription Agreement due to fluctuations in the Market Price
of the Common Stock.

               14.3 Late Filing of Registration Statement. If the Registration
Statement is not filed by the Filing Date, Company shall pay the Holder at a
rate equal to the Accrual Rate, accruing daily until the Registration Statement
is filed, payable in cash or Common Stock, at the Holder's option, as set forth
in Section 2.6 below ("Late Filing Payment").

               14.4 Registration Effective Date. The Company shall use its best
efforts to have the Registration Statement declared effective by the SEC (the
date of such effectiveness is referred to herein as the "Effective Date") as
soon as possible, but in no event shall the Effective Date be later than the Due
Date.

               14.5 Registration Statement Not Effective by Due Date. If the
Registration Statement is not declared effective by the Due Date, the Company
shall pay the Holder at a rate equal to the Accrual Rate, accruing daily until
the Registration Statement or a registration statement filed pursuant to Section
3 of this Agreement is declared effective, payable in cash or Common Stock, at
the Holder's option, as set forth in Section 2.6 below (the "Late Registration
Payment").

               14.6 Late Filing Payment; Late Registration Payment; Ineffective
Registration Payment. Any Late Filing Payment, Late Registration Payment or
Ineffective Registration Payment shall be payable in cash or Common Stock, at
the Holder's option, as follows: If Holder elects to be paid in cash, such Late
Filing Payment, Late Registration Payment or Ineffective Registration Payment
shall be paid to such Holder within five (5) business days following the end of
the month in which such payment was accrued. If Holder elects to be paid in
Common Stock, the Company shall issue to Holder, within five (5) business days
following the end of the month in which such Late Filing Payment, Late
Registration Payment or Ineffective Registration Payment was accrued, a number
of shares of Common Stock equal to the quotient of (i) the dollar amount of such
Late Filing Payment, Late Registration Payment or Ineffective Registration
Payment, divided by (ii) the Market Price, of the Common Stock on the last
Trading Day of the month in which such payment was accrued. Any such shares of
Common Stock issued to the Holder as a result of any Late Filing Payment, Late
Registration Payment or Ineffective Registration Payment shall also be deemed
"Registrable Securities" as defined herein.

               14.7 Shelf Registration. The Registration Statement shall be
prepared as a "shelf" registration statement under Rule 415, and shall be
maintained effective until all Registrable Securities are resold pursuant to
such Registration Statement.

               14.8 Eligibility for Form S-1. The Company represents that it is
presently eligible to effect the registration contemplated hereby on Form S-1
and will use its best efforts to continue to take such actions as are necessary
to maintain such eligibility. The Company covenants to use its best efforts to
use Form S-1 (or other suitable form, at the Company's discretion, but subject
to the reasonable approval of the Holders) for the registration required by this
Section during all applicable times contemplated by this Agreement.



                                       6
   7

               14.9 Supplemental Registration Statement for Three Month Reset
Shares, Six Month Reset Shares or Call Reset Shares. Anytime the Company is
required to issue Three Month Reset Shares, Six Month Reset Shares or Call Reset
Shares, as the case may be, and the Registration Statement does not cover a
sufficient number of shares of Common Stock to cover (i) all outstanding
Registrable Securities plus (ii) all Registrable Securities to be issued as
Three Month Reset Shares, Six Month Reset Shares or Call Reset Shares, as the
case may be, the Company shall prepare and file with the SEC such Supplemental
Registration Statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the
Act with respect to the disposition of all such Registrable Securities and such
Supplemental Registration Statement shall be declared effective prior to the
issuance of such Three Month Reset Shares, such Six Month Reset Shares or Call
Reset Shares.

               14.10 Failure to Obtain Effectiveness of Supplemental
Registration Statement; Failure to Maintain Effectiveness of Registration
Statement.

                      (i) Failure to Obtain Effectiveness of Supplemental 
Registration Statement. In the event that the Company fails to have a
Supplemental Registration Statement declared effective within thirty (30)
business days of the original Three Month Reset Date (as specified in Section
2.2.2(a) of the Subscription Agreement), if required with respect to the Three
Month Reset Shares, within thirty (30) business days of the original Six Month
Reset Date (as specified in Section 2.2.2(b) of the Subscription Agreement), if
required with respect to the Six Month Reset Shares or within thirty (30)
business days of the Call Reset Date, if required with respect to the Call Reset
Shares, the Company shall pay the Holder at a rate equal to the Accrual Rate,
accruing daily until a Supplemental Registration Statement filed pursuant to
Section 2.9 of this Agreement and covering the resale of the Reset Shares is
declared effective, payable in cash or Common Stock, at the Holder's option, as
set forth in Section 2.6 above (the "Ineffective Registration Payment").

                      (ii) Failure to Maintain the Effectiveness of any 
Registration Statement. In the event that the Company fails to maintain the
effectiveness of any Registration Statement (or fails to maintain a current and
deliverable prospectus) during any time period required hereunder (the
"Ineffective Period"), other than a Permissible Black Out Period as specified in
Section 4 below, the Company shall pay the Holder at a rate equal to the Accrual
Rate, accruing daily until a Registration Statement covering the resale of all
such Registrable Securities becomes effective, payable in cash or Common Stock,
at the Holder's option, as set forth in Section 2.6 above (the "Ineffective
Registration Payment"). For the purposes hereof, if a Registration Statement is
effective but does not cover a sufficient number of shares of Common Stock to
effect resales of all Registrable Securities, then a Holder shall be entitled to
an Ineffective Registration Payment for the Ineffective Period only as to the
number of shares of Registrable Securities held by such Holder that are not
covered under the Registration Statement, determined on a pro rata basis among
the Holders based upon the Subscriber Allocation.

               14.11 Failure to Maintain Listing of Common Stock. In the event
that, at any time during the term of the Subscription Agreement, the Company's
Common Stock is not listed for and actively trading on either the Nasdaq Small
Cap Market, Nasdaq National Market, American Stock Exchange or New York Stock
Exchange or is suspended or delisted with respect to the trading of the shares
of Common Stock on such market or exchange (a "Delisting Event"), the Company
shall pay 



                                       7
   8

the Holder at a rate equal to the Accrual Rate, accruing daily until the
Holder's shares of Common Stock become listed for and actively trading on either
the Nasdaq Small Cap Market, Nasdaq National Market, American Stock Exchange or
New York Stock Exchange.

               In the event that a Delisting Event occurs and the Closing Bid
Price of the Common Stock on the first Trading Day that the Company's Common
Stock is actively listed and trading on either the Nasdaq Small Cap Market,
Nasdaq National Market, American Stock Exchange or New York Stock Exchange (the"
Delisting Event Final Price") is less than the Closing Bid Price on the last
Trading Day preceding such Delisting Event (the "Delisting Event Initial
Price"), the Company shall issue to Holder, within five (5) business days
following the first Trading Day after the end of the Delisting Event, an
additional number of shares of Common Stock equal to the difference of (i) a
number of shares equal to the quotient of (x) the Aggregate Outstanding Share
Price divided by (y) the Delisting Event Final Price, minus (ii) a number of
shares equal to the quotient of (x) the Aggregate Outstanding Share Price
divided by (y) the Delisting Event Initial Price. Any such shares of Common
Stock issued to the Holder as a result of any Delisting Event shall also be
deemed "Registrable Securities" as defined herein.

        15. Obligations of the Company. Whenever required under this Agreement
to effect the registration of any Registrable Securities, the Company shall, as
expeditiously and reasonably possible:

               (a) Prepare and file with the Securities and Exchange Commission
("SEC") a Registration Statement with respect to such Registrable Securities and
use its best efforts to cause such Registration Statement to become effective
and to remain effective until all Registrable Securities are resold pursuant to
such Registration Statement.

               (b) Prepare and file with the SEC such amendments and supplements
to such Registration Statement and the prospectus used in connection with such
Registration Statement ("Amended Registration Statement") or prepare and file
any new registration statement ("New Registration Statement," together with the
Amended Registration Statement, "Supplemental Registration Statements") as may
be necessary to comply with the provisions of the Act with respect to the
disposition of all securities covered by such Registration Statement or such
prior registration statement and to cover the resale of all Registrable
Securities.

               (c) Furnish to the Holders such numbers of copies of a
prospectus, including a preliminary prospectus, in conformity with the
requirements of the Securities Act, and such other documents as they may
reasonably request in order to facilitate the disposition of Registrable
Securities owned by them.



                                       8
   9

               (d) Use its best efforts to register and qualify the securities
covered by such Registration Statement under such other securities or Blue Sky
laws of such jurisdictions as shall be reasonably requested by the Holders of
the Registrable Securities covered by such Registration Statement, provided that
the Company shall not be required in connection therewith or as a condition
thereto to qualify to do business or to file a general consent to service of
process in any such states or jurisdictions.

               (e) In the event of any underwritten public offering, enter into
and perform its obligations under an underwriting agreement, in usual and
customary form, with the managing underwriter of such offering. Each Holder
participating in such underwriting shall also enter into and perform its
obligations under such an agreement.

               (f) As promptly as practicable after becoming aware of such
event, notify each Holder of Registrable Securities of the happening of any
event of which the Company has knowledge, as a result of which the prospectus
included in the Registration Statement, as then in effect, includes an untrue
statement of a material fact or omits to state a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading, and subject to Section
4, use its best efforts promptly to prepare a supplement or amendment to the
Registration Statement to correct such untrue statement or omission, and deliver
a number of copies of such supplement or amendment to each Holder as such Holder
may reasonably request.

               (g) Provide Holders with notice of the date that a Registration
Statement registering the resale of the Registrable Securities is declared
effective by the SEC, and the date or dates when the Registration Statement is
no longer effective.

               (h) Provide Holders and their representatives the opportunity and
a reasonable amount of time, based upon reasonable notice delivered by the
Company, to conduct a reasonable due diligence inquiry of Company's pertinent
financial and other records and make available its officers and directors for
questions regarding such information as it relates to information contained in
the Registration Statement.

               (i) Provide Holders and their representatives the opportunity and
ten (10) business days, based on reasonable notice delivered by the Company, to
review the Registration Statement and all amendments thereto a reasonable period
of time prior to their filing with the SEC if so requested by Holder in writing;
provided that if the Holders or their representatives take more than ten (10)
business days for such review and as a direct result the Company cannot file the
Registration Statement by the Filing Date, any Late Filing Payment shall be
tolled for the amount of time that such review exceeded ten (10) business days.

               (j) Provide each Holder with prompt notice of the issuance by the
SEC or any state securities commission or agency of any stop order suspending
the effectiveness of the Registration Statement or the initiation of any
proceeding for such purpose. The Company shall use its best efforts to prevent
the issuance of any stop order, and, if any is issued to obtain the removal
thereof at the earliest possible date.



                                       9
   10

               (k) Use its best efforts to list the Registrable Securities
covered by the Registration Statement with all securities exchanges or markets
on which the Common Stock is then listed and prepare and file any required
filing with the NASD and any other exchange or market on which the Common Stock
is listed.

        16. Black Out. In the event that, during the time that the Registration
Statement is effective, the Company reasonably determines, based upon advice of
counsel, that due to the existence of material non-public information,
disclosure of such material non-public information would be required to make the
statements contained in the Registration Statement not misleading, and the
Company has a bona fide business purpose for preserving as confidential such
material non-public information, the Company shall have the right to suspend the
effectiveness of the Registration Statement, and no Holder shall be permitted to
sell any Registrable Securities pursuant thereto (the "Black Out Period"), until
such time as such suspension is no longer advisable; provided, however, that any
Black Out Period shall not exceed a period of thirty (30) days. If any Black Out
Period exceeds such thirty (30) day limit, the Ineffective Registration
Payments, as specified in Sections 2.10(ii), shall accrue beginning on the first
day that such Black Out Period exceeds the thirty (30) day limit. As soon as
such suspension is no longer advisable, the Company shall, if required,
promptly, but in no event later than the date the Company files any documents
with the Securities and Exchange Commission ("SEC") referencing such material
information, file with the SEC an amendment to the Registration Statement
disclosing such information and use its best efforts to have such amendment
declared effective as soon as possible.

               In the event the effectiveness of the Registration Statement is
suspended by the Company pursuant hereto, the Company shall promptly notify all
Holders whose securities are covered by the Registration Statement of such
suspension, and shall promptly notify each such Holder as soon as the
effectiveness of the Registration Statement has been resumed. The Company shall
be entitled to effect no more than three Black Out Periods during any one (1)
year period not exceeding an aggregate of thirty (30) days during any twelve
month period ("Permissible Black Out Periods").

               In the event that a Black Out Period, other than Permissible
Black Out Periods ("Impermissible Black Out Period"), occurs and the Closing Bid
Price of the Common Stock on the first Trading Day that the Registration
Statement becomes effective after the Impermissible Black Out Period (the "Final
Black Out Price") is less than the Closing Bid Price on the last Trading Day
preceding such Impermissible Black Out Period that the Registration Statement
was effective (the "Initial Black Out Price"), the Company shall issue to
Holder, within five (5) business days following the first Trading Day that the
Registration Statement becomes effective after the 



                                       10
   11

Impermissible Black Out Period, an additional number of shares of Common Stock
equal to the difference of (i) a number of shares equal to the quotient of (x)
the Aggregate Outstanding Share Price divided by (y) the Final Black Out Price,
minus (ii) a number of shares equal to the quotient of (x) the Aggregate
Outstanding Share Price divided by (y) the Initial Black Out Price. Any such
shares of Common Stock issued to the Holder as a result of any Impermissible
Black Out Period shall also be deemed "Registrable Securities" as defined
herein.

        17. Piggyback Registration. If the Registration Statement described in
Section 2 is not effective by the Due Date, and if (but without any obligation
to do so) the Company proposes to register (including for this purpose a
registration effected by the Company for shareholders other than the Holders)
any of its Common Stock under the Act in connection with the public offering of
such securities solely for cash (other than a registration relating solely for
the sale of securities to participants in a Company stock plan or a registration
on Form S-4 promulgated under the Act or any successor or similar form
registering stock issuable upon a reclassification, upon a business combination
involving an exchange of securities or upon an exchange offer for securities of
the issuer or another entity), the Company shall, at such time, promptly give
each Holder written notice of such registration (a "Piggyback Registration
Statement"). Upon the written request of each Holder given by fax within ten
(10) days after mailing of such notice by the Company, the Company shall cause
to be included in such registration statement under the Act all of the
Registrable Securities that each such Holder has requested to be registered
("Piggyback Registration") to the extent such inclusion does not violate the
registration rights of any other security holder of the company granted prior to
the date hereof; provided, however, that nothing herein shall prevent the
Company from withdrawing or abandoning such registration statement prior to its
effectiveness. The election of Holder to participate in a Piggyback Registration
Statement shall not impact the amount payable to Holder pursuant to Section 2.6
herein except that the Late Registration Payment shall cease to accrue as of the
date of effectiveness of the Piggyback Registration Statement.

        18. Limitation on Obligations to Register.

               18.1 Piggyback Registration. In the case of a Piggyback
Registration pursuant to an underwritten public offering by the Company, if the
managing underwriter determines and advises in writing that the inclusion in the
registration statement of all Registrable Securities proposed to be included
would interfere with the successful marketing of the securities proposed to be
registered by the Company, then the number of such Registrable Securities to be
included in the registration statement, to the extent such Registrable
Securities may be included in such Piggyback Registration Statement, shall be
allocated among all Holders who had requested Piggyback Registration pursuant to
the terms hereof, in the proportion that the number of Registrable Securities
which each such Holder, including Swartz, seeks to register bears to the total
number of Registrable Securities sought to be included by all Holders, including
Swartz. If required by the managing underwriter of such an underwritten public
offering, the Holders shall enter into a reasonable agreement limiting the
number of Registrable Securities to be included in such Piggyback Registration
Statement and the terms, if any, regarding the future sale of such Registrable
Securities.



                                       11
   12

               18.2 Dispute as to Registrable Securities. In the event the
Company believes that shares sought to be registered under Section 2 or Section
5 by Holders do not constitute "Registrable Securities" by virtue of Section 2.1
of this Agreement, and the status of those shares as Registrable Securities is
disputed, the Company shall provide, at its expense, an Opinion of Counsel,
reasonably acceptable to the Holders of the Securities at issue (and
satisfactory to the Company's transfer agent to permit the sale and transfer)
that those securities may be sold immediately, without volume limitation or
other material restrictions, without registration under the Act, by virtue of
Rule 144 or similar provisions.

        19. Furnish Information. It shall be a condition precedent to the
obligations of the Company to take any action pursuant to this Agreement with
regard to each Holder, that such Holder shall furnish to the Company such
information regarding Holder, the Registrable Securities held by it, and the
intended method of disposition of such securities as shall be required to effect
the registration of its Registrable Securities or to determine that registration
is not required pursuant to Rule 144 or other applicable provision of the Act.
The Company shall include all information provided by such Holder pursuant
hereto in the Registration Statement, substantially in the form supplied, except
to the extent such information is not permitted by law.

        20. Expenses. All expenses, other than underwriting discounts and
commissions and fees and expenses of counsel to the selling Holders, incurred in
connection with registrations, filings or qualifications pursuant hereto,
including (without limitation) all registration, filing and qualification fees,
printers' and accounting fees, fees and disbursements of counsel for the
Company, shall be borne by the Company.

        21. Indemnification. In the event any Registrable Securities are
included in a Registration Statement or a Piggyback Registration Statement under
this Agreement:

               (a) To the extent permitted by law, the Company will indemnify
and hold harmless each Holder, the officers, directors, partners, legal counsel,
and accountants of each Holder, any underwriter (as defined in the Act) for such
Holder and each person, if any, who controls such Holder or underwriter within
the meaning of Section 15 of the Act or the Securities Exchange Act of 1934, as
amended (the "1934 Act"), against any losses, claims, damages, or liabilities
(joint or several) to which they may become subject under the Act, the 1934 Act
or other federal or state law, insofar as such losses, claims, damages, or
liabilities (or actions in respect thereof) arise out of or are based upon any
of the following statements or omissions: (i) any untrue statement or alleged
untrue statement of a material fact contained in such registration statement,
including any preliminary prospectus or final prospectus contained therein or
any amendments or supplements thereto, or (ii) the omission or alleged omission
to state therein a material fact required to be stated therein, or necessary to
make the statements therein not misleading, and the Company will reimburse each
such Holder, officer or director, underwriter or controlling person for any
legal or other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, damage, liability, or action;
provided, however, that the indemnity agreement contained in this subsection
9(a) shall not apply to amounts paid in settlement of any such loss, claim,
damage, liability, or action if such settlement is effected without the consent
of the Company (which consent shall not be unreasonably withheld), nor shall the
Company be liable in any such case for any such loss, claim, damage, liability,
or action to the extent that it arises out of or is based upon a violation which
occurs in reliance upon and in conformity with written information furnished
expressly for 



                                       12
   13

use in connection with such registration by any such Holder, officer, director,
underwriter or controlling person.

               (b) To the extent permitted by law, each selling Holder,
severally and not jointly, will indemnify and hold harmless the Company, each of
its directors, officers, partners, legal counsel, accountants, each person, if
any, who controls the Company within the meaning of Section 15 of the Act, each
underwriter and each person who controls such underwriter within the meaning of
Section 15 of the Act and any other Holder selling securities in such
registration statement or any of its directors or officers or any person who
controls such Holder, against any losses, claims, damages, or liabilities (joint
or several) to which the Company or any such director, officer, controlling
person, or underwriter or controlling person, or other such Holder or director,
officer or controlling person may become subject, under the Act, the 1934 Act or
other federal or state law, insofar as such losses, claims, damages, or
liabilities (or actions in respect thereto) arise out of or are based upon any
untrue statement or alleged untrue statement of a material fact contained in any
such registration statement or prospectus, or any omission or alleged omission
to state therein a material fact required to be stated therein or necessary to
make the statements not misleading, in each case to the extent (and only to the
extent) that such statement or omission is made in reliance upon and in
conformity with written information furnished by such Holder expressly for use
in connection with such registration statement; and each such Holder will
reimburse any legal or other expenses reasonably incurred by the Company and any
such director, officer, controlling person, underwriter or controlling person,
other Holder, officer, director, or controlling person in connection with
investigating or defending any such loss, claim, damage, liability, or action;
provided, however, that the indemnity agreement contained in this subsection
9(b) shall not apply to amounts paid in settlement of any such loss, claim,
damage, liability or action if such settlement is effected without the consent
of the Holder, which consent shall not be unreasonably withheld. Amounts due
under this subsection shall in no event exceed the net proceeds received by such
Holder from the sale of registrable Securities pursuant to the Registration
Statement in question.

               (c) Promptly after receipt by an indemnified party under this
Section 9 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying party under this Section 9, deliver to
the indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the reasonably incurred fees and
expenses of one such counsel to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential conflicting
interests between such indemnified party and any other party represented by such
counsel in such proceeding. The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such
action, if materially prejudicial to its ability to defend such action, shall
relieve such indemnifying party of any liability to the indemnified party under
this Section 9, but the omission so to deliver written notice to the
indemnifying party will not relieve it of any liability that it may have to any
indemnified party otherwise than under this Section 9.



                                       13
   14

               (d) In the event that the indemnity provided in paragraph (a) or
(b) of this Section 9 is unavailable to or insufficient to hold harmless an
indemnified party for any reason, the Company and each Holder agree to
contribute to the aggregate claims, losses, damages and liabilities (including
legal or other expenses reasonably incurred in connection with investigating or
defending same) (collectively "Losses") to which the Company and one or more of
the Holder may be subject in such proportion as is appropriate to reflect the
relative fault of the Company and the Holders in connection with the statements
or omissions which resulted in such Losses. Relative fault shall be determined
by reference to whether any alleged untrue statement or omission relates to
information provided by the Company or by the Holders. The Company and the
Holders agree that it would not be just and equitable if contribution were
determined by pro rata allocation or any other method of allocation that does
not take account of the equitable considerations referred to above.
Notwithstanding the provisions of this paragraph (d), no person guilty of
fraudulent misrepresentation (within the meaning of Section 10(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. For purposes of this Section 9,
each person who controls a Holder of Registrable Securities within the meaning
of either the Securities Act or the Exchange Act and each director, officer,
partner, employee and agent of a Holder shall have the same rights to
contribution as such holder, and each person who controls the Company within the
meaning of either the Act or the Exchange Act and each director and officer of
the Company shall have the same rights to contribution as the Company, subject
in each case to the applicable terms and conditions of this paragraph (d).

               (e) The obligations of the Company and Holders under this Section
9 shall survive the resale, if any, of the Common Stock, the completion of any
offering of Registrable Securities in a Registration Statement under this
Agreement, and otherwise.

               (f) If the Registration Statement or any Piggyback Registration
involves an underwritten offering, the Company shall enter into such customary
agreements for secondary offerings (including a customary underwriting agreement
with the underwriter or underwriters) and take all such other reasonable actions
reasonably requested by the Holders in connection therewith in order to expedite
or facilitate the disposition of such Registrable Securities and in such
connection:

                      (i) make such representations and warranties to the 
Holders and the underwriter or underwriters in form, substance and scope as are

the underwriter(s) and their counsel and covering, without limitation, such
matters as the due authorization and issuance of the securities being registered
and compliance with securities laws by Company in connection with the
authorization, issuance and registration thereof and other matters that are

certified public accountants addressed to each underwriter stating that such

the certificates, opinions, representations and warranties, comfort letters,
documents and other items referred to in clauses (i) through (iii) of this
subsection, whether or not an underwriter is utilized in connection with the
disposition of Registrable Securities.

        22. Reports Under Securities Exchange Act of 1934. With a view to making
available to the Holders the benefits of Rule 144 promulgated under the Act and
any other rule or regulation of the SEC that may at any time permit a Holder to
sell securities of the Company to the public without registration, the Company
agrees to:

               (a) make and keep public information available, as those terms
are understood and defined in Rule 144;

               (b) use its best efforts to file with the SEC in a timely manner
all reports and other documents required of the Company under the Act and the
1934 Act; and

        23. Amendment of Registration Rights. Any provision of this Agreement
may be amended and the observance thereof may be waived (either generally or in
a particular instance and either retroactively or prospectively), only with the
written consent of the Company and the written consent of each Holder effected
thereby. Any amendment or waiver effected in accordance with this paragraph
shall be binding upon each Holder, each future Holder, and the Company.

        24. Notices. All notices required or permitted under this Agreement
shall be made in writing signed by the party making the same, shall specify the
section under this Agreement pursuant to which it is given, and shall be
addressed if to (i) the Company at: Techniclone Corporation, 14282 Franklin
Avenue, Tustin, CA 92780, Telephone No. (714) 508-6000, Facsimile No. (714)
838-4094 and (ii) the Holders at their respective last address as the party as
shown on the records of the Company. Any notice, except as otherwise provided in
this Agreement, shall be made by fax and shall be deemed given at the time of
transmission of the fax.



                                       15
   16

        25. Termination. This Agreement shall terminate on the date all
Registrable Securities cease to exist (as that term is defined in Section 2.1
hereof); but without prejudice to (i) the parties' rights and obligations
arising from breaches of this Agreement occurring prior to such termination (ii)
other indemnification obligations under this Agreement.

        26. Assignment. No assignment, transfer or delegation, whether by
operation of law or otherwise, of any rights or obligations under this Agreement
by the Company or any Holder, respectively, shall be made without the prior
written consent of the majority in interest of the Holders or the Company,
respectively; provided that the rights of a Holder may be transferred to a
subsequent holder of the Holder's Registrable Securities (provided such
transferee shall provide to the Company, together with or prior to such
transferee's request to have such Registrable Securities included in a Piggyback
Registration, a writing executed by such transferee agreeing to be bound as a
Holder by the terms of this Agreement), and the Company hereby agrees to file an
amended registration statement including such transferee or a selling security
holder thereunder; and provided further that the Company may transfer its rights
and obligations under this Agreement to a purchaser of all or a substantial
portion of its business if the obligations of the Company under this Agreement
are assumed in connection with such transfer, either by merger or other
operation of law (which may include without limitation a transaction whereby the
Registrable Securities are converted into securities of the successor in
interest) or by specific assumption executed by the transferee.

        27. Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of Delaware applicable to agreements made
in and wholly to be performed in that jurisdiction, except for matters arising
under the Act or the Securities Exchange Act of 1934, which matters shall be
construed and interpreted in accordance with such laws.

        28. Execution in Counterparts Permitted. This Agreement may be executed
in any number of counterparts, each of which shall be enforceable against the
parties actually executing such counterparts, and all of which together shall
constitute one (1) instrument.

        29. Specific Performance. The Holder shall be entitled to the remedy of
specific performance in the event of the Company's breach of this Agreement, the
parties agreeing that a remedy at law would be inadequate.

        30. Indemnity. Each party shall indemnify each other party against any
and all claims, damages (including reasonable attorney's fees), and expenses
arising out of the first party's breach of any of the terms of this Agreement.

        31. Entire Agreement; Written Amendments Required. This Agreement,
including the Exhibits attached hereto, the Subscription Agreements, the Common
Stock certificates, the Escrow Agreement, and the other documents delivered
pursuant hereto constitute the full and entire understanding and agreement
between the parties with regard to the subjects hereof and thereof, and no party
shall be liable or bound to any other party in any manner by any warranties,
representations or covenants except as specifically set forth herein or therein.
Except as expressly provided herein, neither this Agreement nor any term hereof
may be amended, waived, discharged or terminated other than by a written
instrument signed by the party against whom enforcement of any such amendment,
waiver, discharge or termination is sought.

               THIS WARRANT AND THE SECURITIES ISSUABLE UPON EXERCISE HEREOF
HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
"SECURITIES ACT"), OR ANY STATE SECURITIES LAW, AND MAY NOT BE SOLD,
TRANSFERRED, PLEDGED, HYPOTHECATED OR OTHERWISE DISPOSED OF OR EXERCISED UNLESS
(i) A REGISTRATION STATEMENT UNDER THE SECURITIES ACT AND APPLICABLE STATE
SECURITIES LAWS SHALL HAVE BECOME EFFECTIVE WITH REGARD THERETO, OR (ii) AN
EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT AND APPLICABLE STATE
SECURITIES LAWS IS AVAILABLE IN CONNECTION WITH SUCH OFFER, SALE OR TRANSFER.

               AN INVESTMENT IN THESE SECURITIES INVOLVES A HIGH DEGREE OF RISK.
HOLDERS MUST RELY ON THEIR OWN ANALYSIS OF THE INVESTMENT AND ASSESSMENT OF THE
RISKS INVOLVED. SEE THE RISK FACTORS SET FORTH UNDER THAT CERTAIN REGULATION D

               Warrant to Purchase

               _______ shares

                        WARRANT TO PURCHASE COMMON STOCK
                                       OF
                             TECHNICLONE CORPORATION

                      THIS CERTIFIES that ________________ or any subsequent 
holder hereof ("Holder"), has the right to purchase from TECHNICLONE
CORPORATION, a Delaware corporation (the "Company"), up to _______________ fully
paid and nonassessable shares of the Company's common stock, $.001 par value per
share ("Common Stock"), subject to adjustment as provided herein, at a price
equal to the Exercise Price as defined in Section 3 below, at any time beginning
on the Date of Issuance (defined below) and ending at 5:00 p.m., New York, New
York 


   2

time, on December 31, 2004 (the "Exercise Period").

                      Holder agrees with the Company that this Warrant to 
Purchase Common Stock of Techniclone Corporation (this "Warrant") is issued and
all rights hereunder shall be held subject to all of the conditions, limitations
and provisions set forth herein.

        32.    Date of Issuance.

                      This Warrant shall be deemed to be issued on June 16th, 
1998 ("Date of Issuance").

        33.    Exercise.

               (a) Manner of Exercise. During the Exercise Period, this Warrant
may be exercised as to all or any lesser number of full shares of Common Stock
covered hereby (the "Warrant Shares") upon surrender of this Warrant, with the
Exercise Form attached hereto as Exhibit A (the "Exercise Form") duly completed
and executed, together with the full Exercise Price (as defined below) for each
share of Common Stock as to which this Warrant is exercised, at the office of
the Company, 14282 Franklin Avenue, Tustin, CA 92780, Attention: Elizabeth
Gorbett-Frost, Chief Financial Officer, Telephone No. (714) 508-6000, Telecopy
No. (714) 838-4094, or at such other office or agency as the Company may
designate in writing, by overnight mail, with an advance copy of the Exercise
Form sent to the Company and its Transfer Agent by facsimile (such surrender and
payment of the Exercise Price hereinafter called the "Exercise of this
Warrant").

               (b) Date of Exercise. The "Date of Exercise" of the Warrant shall
be defined as the date that the advance copy of the completed and executed
Exercise Form is sent by facsimile to the Company, provided that the original
Warrant and Exercise Form are received by the Company as soon as practicable
thereafter. Alternatively, the Date of Exercise shall be defined as the date the
original Exercise Form is received by the Company, if Holder has not sent
advance notice by facsimile.

               (c) Cancellation of Warrant. This Warrant shall be canceled upon
the Exercise of this Warrant, and, as soon as practical after the Date of
Exercise, Holder shall be entitled to receive Common Stock for the number of
shares purchased upon such Exercise of this Warrant, and if this Warrant is not
exercised in full, Holder shall be entitled to receive a new Warrant (containing
terms identical to this Warrant) representing any unexercised portion of this
Warrant in addition to such Common Stock.

               (d) Holder of Record. Each person in whose name any Warrant for
shares of Common Stock is issued shall, for all purposes, be deemed to be the
Holder of record of such shares on the Date of Exercise of this Warrant,
irrespective of the date of delivery of the Common Stock purchased upon the
Exercise of this Warrant. Nothing in this Warrant shall be construed as
conferring upon Holder any rights as a stockholder of the Company.

               (e) Limitation on Exercise. Notwithstanding anything to the
contrary contained herein, this Warrant may not be exercised by the Warrant
Holder to the extent that, after giving 



                                       2
   3

effect to Warrant Shares to be issued pursuant to an Exercise Form, the total
number of shares of Common Stock deemed beneficially owned by such Holder (other
than by virtue of ownership of this Warrant, or ownership of other securities
that have limitations on the Holder's rights to convert or exercise similar to
the limitations set forth herein), together with all shares of Common Stock
deemed beneficially owned by the Holder's "affiliates" (as defined in Rule 144
of the Securities Act) that would be aggregated for purposes of determining
whether a group under Section 13(d) of the Securities Exchange Act of 1934, as
amended (the "Exchange Act") exists, would exceed 9.9%; provided that (w) each
Warrant Holder shall have the right at any time and from time to time to reduce
such percentage from 9.9% immediately upon notice to the Company or in the event
of a Change in Control Transaction, as defined below, (x) each Warrant Holder
shall have the right at any time and from time to time to increase such
percentage from 9.9% or otherwise waive in whole or in part the restrictions of
this Section 2(e) upon 61 days' prior notice to the Company or immediately in
the event of a Change in Control Transaction, (y) each Warrant Holder can make
subsequent adjustments pursuant to (w) or (x) any number of times from time to
time (which adjustment shall be effective immediately if it results in a
decrease in the percentage or shall be effective upon 61 days' prior written
notice or immediately in the event of a Change in Control Transaction if it
results in an increase in percentage) and (z) each Warrant Holder may eliminate
or reinstate this limitation at any time and from time to time (which
elimination will be effective upon 61 days' prior notice and which reinstatement
will be effective immediately). Without limiting the foregoing, in the event of
a Change in Control Transaction, any holder may reinstate immediately (in whole
or in part) the requirement that any increase in the percentage be subject to 61
days' prior written notice, notwithstanding such Change in Control Transaction,
without imposing such requirement on, or otherwise changing such Holder's rights
with respect to, any other Change in Control Transaction. For this purpose, any
material modification of the terms of a Change in Control Transaction will be
deemed to create a new Change in Control Transaction. A "Change in Control
Transaction" will be deemed to have occurred upon the earlier of the
announcement or consummation of a transaction or series of transactions
involving (x) any consolidation or merger of the Company with or into any other
corporation or other entity or person (whether or not the Company is the
surviving corporation), or any other corporate reorganization or transaction or
series of related transactions in which in excess of 50% of the Company's voting
power is transferred through a merger, consolidation, tender offer or similar
transaction, or (y) in excess of 50% of the Corporation's Board of Directors
consists of directors not nominated by the prior Board of Directors of the
Company, or (z) any person (as defined in Section 13(d) of the Exchange Act),
together with its affiliates and associates (as such terms are defined in Rule
405 under the Act), beneficially owns or is deemed to beneficially own (as
described in Rule 13d-3 under the Exchange Act without regard to the 60-day
exercise period) in excess of 50% of the Company's voting power. The delivery of
an Exercise Form by the Warrant Holder shall be deemed a representation by such
Holder that it is in compliance with this paragraph. Notwithstanding anything in
this subsection (e), the exercise of this Warrant may only be deferred until
December 31, 2004.

        34.    Payment of Warrant Exercise Price.

                      The Exercise Price shall equal $1.375 per share ("Exercise

                      Price"). Payment of the Exercise Price may be made, by
cashless exercise only,: by surrender of this Warrant at the principal office of
the Company together with notice of cashless



                                       3
   4

exercise, in which event the Company shall issue Holder a number of shares of
Common Stock computed using the following formula:

                                        X = Y (A-B)/A

               where: X = the number of shares of Common Stock to be issued to 
Holder.

                      Y = the number of shares of Common Stock for which this 
Warrant is being exercised.

                             A = the Market Price of one (1) share of Common
               Stock (for purposes of this Section 3(ii), the "Market Price"
               shall be defined as the average closing bid price of the Common
               Stock for the five (5) trading days prior to the Date of Exercise
               of this Warrant (the "Average Closing Price"), as reported by the
               National Association of Securities Dealers Automated Quotation
               System ("Nasdaq") Small Cap Market, or if the Common Stock is not
               traded on the Nasdaq Small Cap Market, the Average Closing Price
               in any other over-the-counter market; provided, however, that if
               the Common Stock is listed on a stock exchange, the Market Price
               shall be the Average Closing Price on such exchange for the five
               (5) trading days prior to the date of exercise of the Warrants.
               If the Common Stock is/was not traded during the five (5) trading
               days prior to the Date of Exercise, then the closing price for
               the last publicly traded day shall be deemed to be the closing
               price for any and all (if applicable) days during such five (5)
               trading day period.

                             B = the Exercise Price.

               For purposes of Rule 144 and sub-section (d)(3)(ii) thereof, it
is intended, understood and acknowledged that the Common Stock issuable upon
exercise of this Warrant in a cashless exercise transaction shall be deemed to
have been acquired at the time this Warrant was issued. Moreover, it is
intended, understood and acknowledged that the holding period for the Common
Stock issuable upon exercise of this Warrant in a cashless exercise transaction
shall be deemed to have commenced on the date this Warrant was issued.

        35.    Transfer and Registration.



                                       4
   5

               (a) Transfer Rights. Subject to the provisions of Section 8 of
this Warrant, this Warrant may be transferred on the books of the Company, in
whole or in part, in person or by attorney, upon surrender of this Warrant
properly completed and endorsed. This Warrant shall be canceled upon such
surrender and, as soon as practicable thereafter, the person to whom such
transfer is made shall be entitled to receive a new Warrant or Warrants as to
the portion of this Warrant transferred, and Holder shall be entitled to receive
a new Warrant as to the portion hereof retained.

               (b) Registrable Securities. The Common Stock issuable upon the
exercise of this Warrant constitutes "Registrable Securities" under that certain
Registration Rights Agreement dated on or about June 16th, 1998 between the
Company and certain investors and, accordingly, has the benefit of the
registration rights pursuant to that agreement.

        36.    Anti-Dilution Adjustments.

               (a) Stock Dividend. If the Company shall at any time declare a
dividend payable in shares of Common Stock, then Holder, upon Exercise of this
Warrant after the record date for the determination of holders of Common Stock
entitled to receive such dividend, shall be entitled to receive upon Exercise of
this Warrant, in addition to the number of shares of Common Stock as to which
this Warrant is exercised, such additional shares of Common Stock as such Holder
would have received had this Warrant been exercised immediately prior to such
record date and the Exercise Price will be proportionately adjusted.

               (b) Recapitalization or Reclassification. If the Company shall at
any time effect a recapitalization, reclassification or other similar
transaction of such character that the shares of Common Stock shall be changed
into or become exchangeable for a larger or smaller number of shares, then upon
the effective date thereof, the number of shares of Common Stock which Holder
shall be entitled to purchase upon Exercise of this Warrant shall be increased
or decreased, as the case may be, in direct proportion to the increase or
decrease in the number of shares of Common Stock by reason of such
recapitalization, reclassification or similar transaction, and the Exercise
Price shall be, in the case of an increase in the number of shares,
proportionally decreased and, in the case of decrease in the number of shares,
proportionally increased. The Company shall give Holder the same notice it
provides to holders of Common Stock of any transaction described in this Section
5(b).

               (c) Distributions. If the Company shall at any time distribute
for no consideration to holders of Common Stock cash, evidences of indebtedness
or other securities or assets (other than cash dividends or distributions
payable out of earned surplus or net profits for the current or preceding years)
then, in any such case, Holder shall be entitled to receive, upon Exercise of
this Warrant, with respect to each share of Common Stock issuable upon such
exercise, the amount of cash or evidences of indebtedness or other securities or
assets which Holder would have been entitled to receive with respect to each
such share of Common Stock as a result of the happening of such event had this
Warrant been exercised immediately prior to the record date or other date fixing
shareholders to be affected by such event (the "Determination Date") or, in lieu
thereof, if the Board of Directors of the Company should so determine at the
time of such distribution, a reduced Exercise Price determined by multiplying
the Exercise Price on the Determination Date by a fraction, the numerator of
which is the result of such Exercise Price 



                                       5
   6

reduced by the value of such distribution applicable to one share of Common
Stock (such value to be determined by the Board of Directors of the Company in
its discretion) and the denominator of which is such Exercise Price.

               (d) Notice of Consolidation or Merger. In the event of a merger,
consolidation, exchange of shares, recapitalization, reorganization, or other
similar event, as a result of which shares of Common Stock shall be changed into
the same or a different number of shares of the same or another class or classes
of stock or securities or other assets of the Company or another entity or there
is a sale of all or substantially all the Company's assets (a "Corporate
Change"), then this Warrant shall be exerciseable into such class and type of
securities or other assets as Holder would have received had Holder exercised
this Warrant immediately prior to such Corporate Change; provided, however, that
Company may not affect any Corporate Change unless it first shall have given
thirty (30) days notice to Holder hereof of any Corporate Change.

               (e) Exercise Price Adjusted. As used in this Warrant, the term
"Exercise Price" shall mean the purchase price per share specified in Section 3
of this Warrant, until the occurrence of an event stated in subsection (a), (b)
or (c) of this Section 5, and thereafter shall mean said price as adjusted from
time to time in accordance with the provisions of said subsection. No such
adjustment under this Section 5 shall be made unless such adjustment would
change the Exercise Price at the time by $.01 or more; provided, however, that
all adjustments not so made shall be deferred and made when the aggregate
thereof would change the Exercise Price at the time by $.01 or more. No
adjustment made pursuant to any provision of this Section 5 shall have the net
effect of increasing the Exercise Price. The number of shares of Common Stock
subject hereto shall increase proportionately with each decrease in the Exercise
Price.

               (f) Adjustments: Additional Shares, Securities or Assets. In the
event that at any time, as a result of an adjustment made pursuant to this
Section 5, Holder shall, upon Exercise of this Warrant, become entitled to
receive shares and/or other securities or assets (other than Common Stock) then,
wherever appropriate, all references herein to shares of Common Stock shall be
deemed to refer to and include such shares and/or other securities or assets;
and thereafter the number of such shares and/or other securities or assets shall
be subject to adjustment from time to time in a manner and upon terms as nearly
equivalent as practicable to the provisions of this Section 5.

        37.    Fractional Interests.

                             No fractional shares or scrip representing 
fractional shares shall be issuable upon the Exercise of this Warrant, but on
Exercise of this Warrant, Holder may purchase only a whole number of shares of
Common Stock. If, on Exercise of this Warrant, Holder would be entitled to a
fractional share of Common Stock or a right to acquire a fractional share of
Common Stock, such fractional share shall be disregarded and the number of
shares of Common Stock issuable upon exercise shall be the next higher number of
shares.

        38.    Reservation of Shares.



                                       6
   7

                             The Company shall at all times reserve for issuance
such number of authorized and unissued shares of Common Stock (or other
securities substituted therefor as herein above provided) as shall be sufficient
for the Exercise of this Warrant and payment of the Exercise Price. The Company
covenants and agrees that upon the Exercise of this Warrant, all shares of
Common Stock issuable upon such exercise shall be duly and validly issued, fully
paid, nonassessable and not subject to preemptive rights, rights of first
refusal or similar rights of any person or entity. 

39. Restrictions on Transfer.

               (a) Registration or Exemption Required. This Warrant has been
issued in a transaction exempt from the registration requirements of the Act by
virtue of Regulation D and exempt from state registration under applicable state
laws. The Warrant and the Common Stock issuable upon the Exercise of this
Warrant may not be pledged, transferred, sold or assigned except pursuant to an
effective registration statement or an exemption to the registration
requirements of the Act and applicable state laws.

               (b) Assignment. If Holder can provide the Company with reasonably
satisfactory evidence that the conditions of (a) above regarding registration or
exemption have been satisfied, Holder may sell, transfer, assign, pledge or
otherwise dispose of this Warrant, in whole or in part. Holder shall deliver a
written notice to Company, substantially in the form of the Assignment attached
hereto as Exhibit B, indicating the person or persons to whom the Warrant shall
be assigned and the respective number of warrants to be assigned to each
assignee. The Company shall effect the assignment within ten (10) days, and
shall deliver to the assignee(s) designated by Holder a Warrant or Warrants of
like tenor and terms for the appropriate number of shares.

        40. Benefits of this Warrant.

                             Nothing in this Warrant shall be construed to 
confer upon any person other than the Company and Holder any legal or equitable
right, remedy or claim under this Warrant and this Warrant shall be for the sole
and exclusive benefit of the Company and Holder.

        41.    Applicable Law.

                             This Warrant is issued under and shall for all 
purposes be governed by and construed in accordance with the laws of the state
of Delaware, without giving effect to conflict of law provisions thereof.

        42.    Loss of Warrant.

the Company, and upon surrender and cancellation of this Warrant, if mutilated,

Techniclone Corporation Announces $20 Million Financing; Techniclone Secures
Equity-Based Line of Credit

Business Editors

        TUSTIN, Calif. - (BUSINESS WIRE) -- June 16, 1998 -- Techniclone Corp.
(Nasdaq:TCLN) announced today that it has secured access to $20,000,000 under an
equity-based line of credit with two institutional investors.

        The equity line of credit provides for immediate funding of $3,500,000
in exchange for the sale of the company's common stock at current market value
(subject to certain adjustments as defined in the transaction agreements). The
company is not required to utilize any funds beyond the initial $3,500,000
funding.

        The remainder of the commitment will be available for use through June
2001, with the decision to sell additional common stock and the timing of such
sales being solely at the company's discretion, subject to certain conditions
including registration of the shares. Future stock issuances under the line of
credit will be priced at 15 percent discount to the then current market price.

        "We are very pleased to have secured this financing. This is an
important strategic funding for the company as we continue our proactive
clinical trial programs. Additionally, it strengthens our financial position in
our pursuit of licensing partners for our broad base of platform technologies,"
stated Larry Bymaster, president and chief executive officer.

        "This is a significant milestone in our long-term financing and
strategic objectives, with the added advantage of gaining a well regarded
institutional investor with expertise in the biotechnology market. This type of
financing allows the company the opportunity to take advantage of potentially
favorable market conditions and gives the company control as to the timing and
amount of future draw downs," Elizabeth Gorbett-Frost, chief financial officer,
concluded.

        Techniclone Corporation is a biotechnology company focused on the
research, development and commercialization of novel cancer therapeutics in two
principal areas: 1) direct tumor targeting agents for the treatment of
refractory malignant lymphoma and 2) collateral targeting agents for the
treatment of solid tumors. Oncolym(R), the Company's most advanced drug
development candidate, is an investigational radiolabeled murine monoclonal
antibody being studied in a Phase II/III trial for the treatment of intermediate
- - and high-grade relapsed or refractory B-cell non-Hodgkins lymphoma.
Additionally, the Company is conducting a Phase I study of its Tumor Narcosis
Therapy (TNT) for the treatment of malignant glioma (brain cancer). The Company
is also developing additional product candidates from the following collateral
targeting agents for solid tumor therapy: Vascular Targeting Agents (VTAs) and
Vasopermeation Enhancement (VEAs). Techniclone Corporation intends to
commercialize these products through the establishment of strategic corporate
collaborations.

Reform Act of 1995. Actual events or results may differ from the Company's
