attached hereto as Exhibit B, and any description thereof is qualified in
its entirety by reference thereto.

     As also provided by the April 1998 Purchase Agreement, IBT has

      3.13MATERIAL CONTRACTS

     The exhibit list to the Company's Annual Report on Form 10-K for the
year ended December 31, 1997 (the "1997 Form 10-K") contains a true and
complete list of all Material Contracts (as defined below) to which the
Company is a party or by which it or its assets may be bound.  The Company
is, and, to the best of the Company's knowledge, all other parties to such
Material Contracts (other than the Company) are, in compliance in all
material respects with their obligations thereunder.  "Material Contracts"
means the agreements, obligations and undertakings which are material to
the business or operations of the Company.  Without limiting the generality
of the foregoing, any agreement, obligation or undertaking will be deemed
to be a Material Contract if a breach thereof or default thereunder would
have a Material Adverse Effect.

      3.14TITLE TO PROPERTIES AND ASSETS, LIENS, ETC.

     Other than as disclosed in the SEC Documents, the Company has good and
marketable title to its properties and assets, and good title to its
leasehold estates, in each case subject to no mortgage, pledge, lien,
lease, encumbrance, or charge, other than (i) those resulting from taxes
which have not yet become delinquent, (ii) minor liens and encumbrances
which do not materially detract from the value of the property subject
thereto or have a Material Adverse Effect on the Company, and (iii) those
that have otherwise arisen in the ordinary course of business.

      3.15PATENTS AND TRADEMARKS

     To the best of the Company's knowledge, the Company has sufficient
title and ownership of or rights to use such trade names, copyrights, trade
secrets, information, patents, trademarks, service marks, rights and
processes (including all applications therefor) as are necessary for its
business as now conducted and as proposed to be conducted, without any
conflict with or infringement of the rights of others.  Except as set forth
in the exhibit list to the Company's 1997 Form 10-K, there are no material
options, licenses, or agreements of any kind relating to the foregoing, nor
is the Company bound by or a party to any material options, licenses or
agreements of any kind with respect to the patents, trademarks, service
<PAGE>
CUSIP No. 87612M108                                     Page 15 of 52 Pages

marks, trade names, copyrights, trade secrets, licenses, proprietary rights
and processes of any other person or entity.  The Company has not received
any communications alleging that the Company has violated or, by conducting
its business as now conducted or proposed, would violate any of the
patents, trademarks, service marks, trade names, copyrights or trade
secrets or other proprietary rights of any other person or entity.  The
Company is not aware that any of its employees is obligated under any
contract (including licenses, covenants or commitments of any nature) or
other agreement, or subject to any judgment, decree or order of any court
or administrative agency, that would interfere with the use of his or her
best efforts to promote the interests of the Company or that would conflict
with the Company's business as now conducted or proposed to be conducted. 
To the best of the Company's knowledge, no person or entity is infringing
or threatening to infringe the patents, trademarks, service marks, trade
names, copyrights or trade secrets or other proprietary rights of the
Company.  All employees, officers and directors, other than those employees
who are not privy to any of the Company's confidential information, are
bound by confidentiality and assignment of intellectual property and
technology agreements and such agreements and obligations do not confer on
any such person any rights of the intellectual property of the Company.

      3.16LABOR MATTERS

     The Company has no collective bargaining agreement with any of its
employees and there is no labor union organizing activity pending or
threatened with respect to the Company.  There are no disputes pending or,
to the knowledge of the Company, threatened between the Company, on the one
hand, and any of its employees, on the other hand, other than employee
grievances arising in the ordinary course of business which would not,
individually or in the aggregate, have a Material Adverse Effect.

   4.REPRESENTATIONS AND WARRANTIES OF THE INVESTORS

     Each Investor hereby represents and warrants to the Company, severally
and not jointly, that:

      4.1AUTHORIZATION

     All acts and conditions necessary for the authorization, execution,
delivery and consummation by the Investor of this Agreement and the
transactions contemplated hereby have been, or will prior to the Closing
be, taken, performed and obtained.  This Agreement constitutes a valid and
legally binding obligation of the Investor, enforceable in accordance with
its terms, except as (a) such enforceability may be limited by bankruptcy,
<PAGE>
CUSIP No. 87612M108                                     Page 16 of 52 Pages

insolvency or similar laws affecting creditors' rights generally and
(b) the availability of equitable remedies may be limited by equitable
principles of general applicability.  The Investor has full power and
authority to execute, deliver and perform its obligations under this
Agreement and to own the Securities.  The execution, delivery and
performance of this Agreement and the consummation of the transactions
contemplated hereby will not conflict with or constitute a violation or
default under any provision of the charter or bylaws of the Investor, or of
any material agreement, indenture or other instrument to which the Investor
is a party, or by which it or its properties or assets are bound, or of any
order, judgment or decree against or binding upon such Investor.

      4.2EXEMPTION FROM REGISTRATION

     Except as provided in the Investor Rights Agreement, the Investor has
been advised that none of the Securities to be purchased by the Investor
hereunder are being registered under the Securities Act, or applicable
state or foreign securities laws, but are being offered and sold pursuant
to exemptions from such laws.  The Investor acknowledges that the Company
is relying in part upon the Investor's representations and warranties
contained herein for the purpose of qualifying the offer and sale of the
Securities proposed to be offered and sold hereunder for applicable
exemptions from registration or qualification pursuant to federal or state
securities laws, rules and regulations.

      4.3PURCHASE ENTIRELY FOR OWN ACCOUNT

     The Securities to be received by the Investor will be acquired for
investment for the Investor's own account, not as a nominee or agent, and
not with a view to the distribution of any part thereof in a manner
contrary to the Securities Act or any applicable federal or state
securities law, and the Investor has no present intention of selling,
granting any participation in, or otherwise distributing the same in a
manner contrary to the Securities Act or any applicable federal or state
securities law.  The Investor does not have any contract, undertaking,
agreement or arrangement with any person to sell, transfer or grant
participations to such person or to any third person with respect to any of
the Securities.

      4.4INVESTMENT EXPERIENCE

     The Investor qualifies as an "accredited investor" as defined in
Rule 501(a) of Regulation D promulgated by the SEC that meets the
requirements of Rule 501(a)(1), (2), (3), or (7) of said Regulation D, and
<PAGE>
CUSIP No. 87612M108                                     Page 17 of 52 Pages
acknowledges that an investment in the Securities involves a high degree of
risk.  The Investor is able to fend for itself in the transactions
contemplated by this Agreement, can bear the economic risk of its
investment (including possible complete loss of such investment) for an
indefinite period of time and has such knowledge and experience in
financial or business matters that it is capable of evaluating the merits
and risks of the investment in the Securities.  The Investor has not been
organized for the purpose of acquiring the Securities.

      4.5ACCESS TO INFORMATION

     The Investor has been furnished such information as it deems necessary
to evaluate an investment in the Securities.  The Investor has been given
access to sufficient information regarding the Company, including
information regarding the current financial condition, results of
operations, business, properties and management of the Company and the
risks associated therewith and has utilized such access to its satisfaction
for the purpose of obtaining information or verifying information.  The
Investor has either attended or been given reasonable opportunity to attend
a meeting with representatives of the Company for the purpose of asking
questions of, and receiving answers from, such representatives concerning
the terms and conditions of the offering of the Securities and to obtain
any additional information, to the extent reasonably available.  The
foregoing representations in this Section 4.5 shall not be deemed to limit
the Company's representations contained in Section 3 of this Agreement.

      4.6RESTRICTED SECURITIES

     The Investor realizes that none of the Securities to be purchased by
the Investor hereunder have been registered under the Securities Act and
that all of such Securities are characterized under the Securities Act as
"restricted securities" and therefore cannot be sold or transferred unless
subsequently registered under the Securities Act or an exemption from such
registration is available.  In this connection, the Investor represents
that it is familiar with Rule 144 under the Securities Act, as presently in
effect, and understands the resale limitations imposed thereby and by the
Securities Act.

      4.7RESIDENCY

     The Investor represents that it is a bona fide resident of or is
domiciled in the jurisdiction indicated on Exhibit A hereto.

respect to any fraction of a share called for upon the exercise of this
Warrant, the Company shall pay in cash or check to the holder of this
Warrant an amount equal to such fraction multiplied by the difference
between (a) the closing sale price, as of the date immediately preceding
the date of exercise of this Warrant, of one share of the Company's Common
Stock as reported on the Nasdaq Stock Market and (b) the Exercise Price.

     Issuance of certificates for Warrant Shares upon the exercise of this

certificate, all of which taxes and expenses shall be paid by the Company,
and such certificates shall be issued in the name of the holder of this
Warrant or in such name or names as may be directed by the holder of this
Warrant; PROVIDED, HOWEVER, that in the event certificates for Warrant
Shares are to be issued in a name other than the name of the holder of this
Warrant, this Warrant when surrendered for exercise shall be accompanied by
the Assignment Form attached hereto duly executed by the holder hereof.

   5.NO RIGHTS AS SHAREHOLDER

     This Warrant does not entitle the holder hereof to any voting rights
or other rights as a shareholder of the Company prior to the exercise
hereof.

   6.EXCHANGE AND REGISTRY OF WARRANT

     This Warrant is exchangeable, upon the surrender hereof by the
registered holder at the above-mentioned office or agency of the Company,
for a new Warrant of like tenor and dated as of such exchange.  The Company
shall maintain at the above-mentioned office or agency a registry showing
the name and address of the registered holder of this Warrant.  This
Warrant may be surrendered for exchange, transfer or exercise, in
accordance with its terms and subject to compliance with applicable laws,
at such office or agency of the Company, and the Company shall be entitled

   8.SATURDAYS, SUNDAYS AND HOLIDAYS

     If the last or appointed day for the taking of any action or the
expiration of any right required or granted herein shall be a Saturday or a
Sunday or shall be a legal holiday, then such action may be taken or such
right may be exercised on the next succeeding day that is not a legal
holiday.

   9.MERGER, SALE OF ASSETS, ETC.

     If at any time the Company merges or consolidates with or into any
other corporation, effects any reorganization, or sells or conveys all or
substantially all of its assets to any other entity, in a transaction in
which the shareholders of the Company immediately before the transaction
own immediately after the transaction less than a majority of the
outstanding voting securities of the entity (or its parent) succeeding to
the business of the Company (each such transaction, a "corporate
transaction"), then this Warrant shall thereafter entitle the holder to
acquire such number and kind of securities as would have been issuable in
respect of the Warrant Shares (or other securities which were subject to
the purchase rights under this Warrant immediately prior to such corporate
transaction) as a result of such corporate transaction if this Warrant had
been exercised in full for cash immediately prior to such corporate
transaction.  The Exercise Price hereunder shall be adjusted if and to the
extent necessary to reflect such change.  In addition, appropriate
adjustment (as determined in good faith by the Company's Board of
Directors) shall be made in the application of the provisions of this
Warrant with respect to the rights and interest of the holder of this
Warrant after the corporate transaction to the end that the provisions of
this Warrant shall be applicable after such corporate transaction, as near
as reasonably may be.

  10.RECLASSIFICATION, CONVERSION, ETC.

     If the Company at any time shall, by reclassification of securities or
otherwise, change the Warrant Shares into the same or a different number of
securities of any class or classes, this Warrant shall thereafter entitle
the holder to acquire such number and kind of securities as would have been
issuable in respect of the Warrant Shares (or other securities which were
subject to the purchase rights under this Warrant immediately prior to such
reclassification or other change) as a result of such change if this
Warrant had been exercised in full for cash immediately prior to such
change.  The Exercise Price hereunder shall be adjusted if and to the
extent necessary to reflect such change.  If the Warrant Shares or other
securities issuable upon exercise hereof are subdivided or combined into a
greater or smaller number of shares of such security, the number of shares
issuable hereunder shall be proportionately increased or decreased, as the
<PAGE>
CUSIP No. 87612M108                                     Page 29 of 52 Pages

case may be, and the Exercise Price shall be proportionately decreased or
increased, as the case may be, in both cases according to the ratio which
the total number of shares of such security to be outstanding immediately
after such event bears to the total number of shares of such security
outstanding immediately prior to such event.  The Company shall give the
holder prompt written notice of any change in the type of securities
issuable hereunder, any adjustment of the Exercise Price for the securities
issuable hereunder, and any increase or decrease in the number of shares
issuable hereunder.

  11.REGISTRATION RIGHTS

     The Warrant Shares issuable upon exercise or conversion of this
Warrant shall be entitled to the registration rights set forth in that
certain Investor Rights Agreement, dated as of April 17, 1998, between the
Company and the parties listed on Schedule A thereto.

  12.REPRESENTATIONS AND WARRANTIES

     The Company hereby represents, warrants and covenants to the holder
hereof that:

      (a)during the period this Warrant is outstanding, the Company
will reserve from its authorized and unissued Common Stock a sufficient
number of shares to provide for the issuance of Warrant Shares upon the

to the Company's officers who are charged with the duty of executing stock
certificates to execute and issue, or cause to be issued, the necessary
certificates for the Warrant Shares issuable upon exercise of this Warrant;

      (c)the Company has all requisite legal and corporate power to
execute and deliver this Warrant, to sell and issue the Warrant Shares
hereunder and perform its obligations under the terms of this Warrant; and

      (d)the Warrant Shares, when issued in compliance with the
provisions of this Warrant and the Company's Restated Articles of
Incorporation and Amended and Restated Bylaws, will be validly issued,
fully paid and nonassessable, and free of any liens or encumbrances (other
than liens or encumbrances created by or imposed upon the holder of the
Warrant Shares), and will be issued in compliance with all applicable
federal and state securities laws.

  14.COOPERATION

     The Company will not, by amendment of its Restated Articles of
Incorporation or through any reorganization, recapitalization, transfer of
assets, consolidation, merger, dissolution, issue or sale of securities or
any other action, avoid or seek to avoid the observance or performance of

provisions of this Warrant and in the taking of all such reasonable action
as may be necessary or appropriate in order to protect the rights of the

provided, however, that Shares or Warrant Shares shall cease to be treated

      2.FIRST SHELF REGISTRATION

     On or before the date 15 days after the Closing Date, the Company
shall file a registration statement with the Commission with respect to the
registration of all the Registrable Securities held by the Investors and
shall use its best efforts to have such registration statement declared
effective within 90 days of the Closing Date or as soon as practicable
thereafter.  After the effective date of such registration statement, the
Company shall use its best efforts to maintain the registration effective
for the period that ends upon the earliest of (i) the expiration of the
First Shelf Period, (ii) the time at which all Shares and Warrant Shares
(excluding any Shares or Warrant Shares that cease to be Registrable
Securities) have been sold or distributed pursuant to such registration
statement or (iii) the date after which all Shares and Warrant Shares
(excluding any Shares or Warrant Shares that cease to be Registrable
Securities) may be sold without registration in reliance on Rule 144(k)
under the Securities Act (such period, the "First Selling Period"). 
Without intending in any manner to diminish the obligations of the Company
under Section 6(b), if at any time during the First Shelf Period the
Company notifies the Investors that there exists or may exist material
nonpublic information which must be disclosed in order for the registration
statement not to be false or misleading, then the Company may require that
no sales may be made under the registration statement until such time as
disclosure is made or the Company determines that disclosure is not
necessary; provided, however, that the aggregate period of time during
which sales may not be made as a result of the Company's exercise of the
foregoing right shall not exceed 120 days during the First Shelf Period. 
The Company shall use its best efforts to cause any required disclosure to
be made as soon as practicable.

      3.SECOND SHELF REGISTRATION

     The Company will have the option, in its sole discretion, to extend
the effectiveness of the registration statement filed in accordance with
Section 2 hereof, or to file a new registration statement with respect to
all the Registrable Securities held by Investors which shall be declared
effective, for a period that begins on the date two years from the Closing
Date and ends on the earliest of (i) the expiration of the Second Shelf
Period, (ii) the time at which all Registrable Securities have been sold or
distributed pursuant to such registration statement or (iii) the date after
which all Registrable Securities may be sold without registration in
reliance on Rule 144(k) under the Securities Act (such period, the "Second
Selling Period").  Without intending in any manner to diminish the
obligations of the Company under Section 6(b), if at any time during the
Second Shelf Period the Company notifies the Investors that there exists or
may exist material nonpublic information which must be disclosed in order
for the registration statement not to be false or misleading, then the
<PAGE>
CUSIP No. 87612M108                                     Page 38 of 52 Pages

Company may require that no sales may be made under the registration
statement until such time as disclosure is made or the Company determines
that disclosure is not necessary; provided, however, that the aggregate
period of time during which sales may not be made as a result of the
Company's exercise of the foregoing right shall not exceed 60 days in any
calendar year.  The Company shall use its best efforts to cause any
required disclosure to be made as soon as practicable.

      4.ADDITIONAL REGISTRATION RIGHTS

     If, but only if, the Company fails or does not elect to maintain the
existing registration statement and the Company fails or does not elect to
file and maintain a new registration statement in accordance with and for
the time period described in Section 3 hereof, the Investors shall have the
registration rights provided in this Section 4; provided, however, that the
Company will have no obligation hereunder if the First Selling Period
expires prior to the date two years from the Closing Date.

      4.1DEMAND RIGHTS

     If at any time during the Second Selling Period the Company receives
from any Investor a written request that the Company effect a registration
with respect to Registrable Securities owned by such Investor, the Company
shall file within 15 days of receipt of such request a registration
statement covering the Registrable Securities so requested to be registered
and, as soon as practicable, effect such registration so as to permit or
facilitate the sale and distribution of all or such portion of such
Investor's Registrable Securities as are specified in such request;
provided, however, that the Company shall not be obligated to effect any
such registration pursuant to this Section 4.1 if (i) the Investor proposes
to sell Registrable Securities at an aggregate price to the public (net of
any underwriters' discounts or commissions) of less than $500,000, (ii) the
Company shall furnish to the Investor a certificate signed by the President
of the Company stating that, in the good faith judgment of the Board of
Directors of the Company, it would be seriously detrimental to the Company
and its shareholders for such registration to be effected at such time, in
which event the Company will have the right to defer the filing of the
registration statement for a period of not more than 60 days after receipt
of the request of the Investor under this Section 4.1 (provided that with
respect to any individual Investor the Company shall not exercise this
right more than once in any calendar year), (iii) the Investor has
previously requested three such registrations pursuant to this Section 4.1
or (iv) the Company has, within the 12-month period preceding the date of
such request, already effected one such registration for the Investor
pursuant to this Section 4.1.  For the purposes of clauses (iii) and (iv)
of the foregoing proviso, each Initial Investor and all assignees of such
Initial Investor's registration rights under this Agreement shall be
<PAGE>
CUSIP No. 87612M108                                     Page 39 of 52 Pages

considered one Investor.  The Company shall use best efforts to cause any
registration statement filed pursuant to this Section 4.1 to remain
effective for 180 days or such shorter period of time as is required to
effect the sale of all Registrable Securities registered pursuant to such
registration statement.

      4.2PIGGYBACK RIGHTS

      (a)If (but without any obligation to do so) the Company proposes to
register any of its Common Stock under the Securities Act in connection
with the public offering of such stock solely for cash (other than a
registration relating solely to the sale of securities to participants in a
Company stock plan, or a registration on any form that does not include
substantially the same information as would be required to be included in a
registration statement covering the sale of the Registrable Securities),
either for its own account or for the account of Investors exercising
demand registration rights pursuant to Section 4.1 hereof, the Company
shall, at each such time, promptly give each Investor written notice of
such registration.  Upon the written request of an Investor given within
five days after mailing of such notice by the Company, the Company shall,
subject to the provisions of Section 4.2(b), use reasonable efforts to
cause to be registered under the Securities Act all of the Registrable
Securities that each such Investor has requested to be registered.  In the
event that the Company decides for any reason not to complete the
registration of shares of Common Stock other than the Registrable
Securities, the Company shall have no obligation under this Section 4.2 to
continue with the registration of the Registrable Securities.  Any request
pursuant to this Section 4.2(a) to register Registrable Securities as part
of an underwritten public offering of Common Stock shall specify that such
Registrable Securities are to be included in the underwriting on the same
terms and conditions as the shares of Common Stock otherwise being sold
through underwriters under such registration.

      (b)The Company shall not be required under this Section 4.2 to
include any Investor's Registrable Securities in an underwritten offering
of the Company's securities unless such Investor accepts the terms of the
underwriting as agreed upon between the Company and the underwriters
selected by it.  If the underwriters advise the Company that marketing
factors require a limitation on the number of shares, including Registrable
Securities, to be included in such offering, then the Company shall so
advise all Investors of Registrable Securities that would otherwise have
been underwritten pursuant to this Section 4.2, and the number of shares,
including Registrable Securities, that may be included in the registration
shall be apportioned first to the Company, then pro rata among the selling
Investors and any other selling shareholders according to the total amount
of Registrable Securities or other securities requested to be sold in such
<PAGE>
CUSIP No. 87612M108                                     Page 40 of 52 Pages

registration by such selling shareholders (including the selling
Investors), or in such other proportions as shall mutually be agreed to by
such selling shareholders (including the selling Investors), provided that
in no event shall the amount of Registrable Securities be reduced if any
securities are to be included in such underwriting for the account of any
person or entity other than the Company.  

      5.EXPENSES OF REGISTRATION

     All Registration Expenses shall be borne by the Company.  All Selling
Expenses relating to Registrable Securities registered on behalf of each
Investor shall be borne by such Investor on the basis of the number of
shares of Common Stock registered and sold.

      6.OBLIGATIONS OF THE COMPANY

     Whenever required under Section 2, 3 or 4 hereof to effect the
registration of any Registrable Securities, the Company shall, as
expeditiously as reasonably possible:

      (a)Prepare and file with the Commission a registration statement
with respect to such Registrable Securities and use best efforts to cause
such registration statement to become and remain effective at the times and
for the periods provided in this Agreement.

      (b)Prepare and file with the Commission such amendments and
supplements to such registration statement and the prospectus used in
connection with such registration statement as may be necessary to comply
with the provisions of the Securities Act with respect to the disposition
of all securities covered by such registration statement.

      (c)Furnish to the Investors 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 all securities covered by such
registration statement.

      (d)Use reasonable efforts to register and qualify the securities
covered by such registration statement under such state securities or blue
sky laws as shall be reasonably requested by the Investors, 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.

CUSIP No. 87612M108                                     Page 41 of 52 Pages

      (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(s) of such offering.  Each
Investor participating in such registration shall also enter into and
perform its obligations under such an agreement.

      (f)Notify each Investor of Registrable Securities covered by such
registration statement, during the time when a prospectus relating thereto
covered by such registration statement is required to be delivered under
the Securities Act, of the happening of any event as a result of which the
prospectus included in such 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 not misleading in the light of the circumstances then
existing and, at the request of any selling Investor, promptly furnish to
all the selling Investors a reasonable number of copies of a supplement to
or an amendment of such prospectus as may be necessary so that, as
thereafter delivered to the selling Investors, such prospectus shall not
include an untrue statement of a material fact or omit to state a material
fact required to be stated therein necessary to make the statements therein
not misleading in the light of the circumstances under which they were
made.

      7.INFORMATION BY INVESTORS

     Each Investor shall furnish to the Company such information regarding
itself, the Registrable Securities it holds and the distribution proposed
by it as the Company may reasonably request in writing and as shall be
required in connection with any registration, qualification or compliance
referred to in this Agreement.

      8.INDEMNIFICATION AND CONTRIBUTION

      (a)INDEMNIFICATION BY THE COMPANY. Upon the registration of
Registrable Securities, the Company shall indemnify and hold harmless the
Investors and each underwriter, selling agent or other securities
professional, if any, that facilitates the disposition of such Shares, and
each of their respective officers and directors and each person who
controls the Investors, underwriter, selling agent or other securities
professional within the meaning of Section 15 of the Securities Act or
Section 20 of the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), against any losses, claims, damages or liabilities, joint
or several, to which the Investors or such other persons may become subject
under the Securities Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are
based upon an untrue statement or alleged untrue statement of a material
<PAGE>
CUSIP No. 87612M108                                     Page 42 of 52 Pages

fact contained in any registration statement under which the Registrable
Securities are to be registered under the Securities Act, or any prospectus
contained therein or furnished by the Company to the Investors or other
such person, or any amendment or supplement thereto, or arise out of or are
based upon 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 hereby agrees to reimburse the
Investors or other person for any legal or other expenses reasonably
incurred by them in connection with investigating or defending any such
action or claim as such expenses are incurred; provided, however, that the
Company shall not be liable to the Investors or other person in any such
case to the extent that any such loss, claim, damage or liability arises
out of or is based upon an untrue statement or alleged untrue statement or
omission or alleged omission made in such registration statement or
prospectus, or amendment or supplement, in reliance upon and in conformity
with written information furnished to the Company by the Investors or such
other person expressly for use therein.

      (b)INDEMNIFICATION BY THE INVESTORS.  Each Investor agrees, as a
consequence of the inclusion of the Investor in such registration, and each
underwriter, selling agent or other securities professional, if any, which
facilitates the disposition of such Registrable Securities shall agree, as
a consequence of facilitating such disposition of Registrable Securities,
severally and not jointly, to (i) indemnify and hold harmless the Company,
its directors, officers who sign any registration statement with respect to
the Registrable Securities and each person, if any, who controls the
Company within the meaning of either Section 15 of the Securities Act or
Section 20 of the Exchange Act, against any losses, claims, damages or
liabilities to which the Company or such other persons may become subject,
under the Securities Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are
based upon an untrue statement or alleged untrue statement of a material
fact contained in such registration statement or prospectus, or any
amendment or supplement, or arise out of or are based upon 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, in each
case to the extent, but only to the extent, that such untrue statement or
alleged untrue statement or omission or alleged omission was made in
reliance upon and in conformity with written information furnished to the
Company by the Investor, underwriter, selling agent or other securities
professional expressly for use therein, and (ii) reimburse the Company for
any legal or other expenses reasonably incurred by the Company in
connection with investigating or defending any such action or claim as such
expenses are incurred.

      (c)NOTICES OF CLAIMS, ETC.  Promptly after receipt by an indemnified
<PAGE>
CUSIP No. 87612M108                                     Page 43 of 52 Pages

party under subsection (a) or (b) above of notice of the commencement of
any action, such indemnified party shall, if a claim in respect thereof is
to be made against an indemnifying party under this Section 8, notify such
indemnifying party in writing of the commencement thereof; but the omission
so to notify the indemnifying party shall not relieve it from any liability
which it may have to any indemnified party otherwise than under this
Section 8.  In case any such action shall be brought against any
indemnified party and it shall notify an indemnifying party of the
commencement thereof, such indemnifying party shall be entitled to
participate therein and, to the extent that it shall wish, jointly with any
other indemnifying party similarly notified, to assume the defense thereof,
with counsel satisfactory to such indemnified party (who shall not, except
with the consent of the indemnified party, be counsel to the indemnifying
party), and, after notice from the indemnifying party to such indemnified
party of its election so to assume the defense thereof, such indemnifying
party shall not be liable to such indemnified party under this Section 8
for any legal expenses of other counsel or any other expenses, in each case
subsequently incurred by such indemnified party, in connection with the
defense thereof other than reasonable costs of investigation, unless
representation of such indemnifying party and such indemnified party by the
same counsel would be inappropriate due to actual or potential conflicting
interests between such parties.  No indemnifying party shall, without the
written consent of the indemnified party, effect the settlement or
compromise of, or consent to the entry of any judgment with respect to, any
pending or threatened action or claim in respect of which indemnification
or contribution may be sought hereunder (whether or not the indemnified
party is an actual or potential party to such action or claim) unless such
settlement, compromise or judgment (i) includes an unconditional release of
the indemnified party from all liability arising out of such action or
claim and (ii) does not include a statement as to, or an admission of,
fault, culpability or a failure to act, by or on behalf of any indemnified
party.

      (d)CONTRIBUTION.  If the indemnification provided for in this
Section 8 is unavailable to or insufficient to hold harmless an indemnified
party under subsection (a) or (b) above in respect of any losses, claims,
damages or liabilities (or actions in respect thereof) referred to therein,
then each indemnifying party shall contribute to the amount paid or payable
by such indemnified party as a result of such losses, claims, damages or
liabilities (or actions in respect thereof) in such proportion as is
appropriate to reflect the relative fault of the indemnifying party and the
indemnified party in connection with the statements or omissions which
resulted in such losses, claims, damages or liabilities (or actions in
respect thereof), as well as any other relevant equitable considerations. 
The relative fault of such indemnifying party and indemnified party shall
be determined by reference to, among other things, whether the untrue or
<PAGE>
CUSIP No. 87612M108                                     Page 44 of 52 Pages

alleged untrue statement of a material fact or omission or alleged omission
to state a material fact relates to information supplied by such
indemnifying party or by such indemnified party, and the parties' relative
intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission.  The parties hereto agree that it would
not be just and equitable if contribution pursuant to this Section 8(d)
were determined by pro rata allocation (even if the Investors or any
underwriters, selling agents or other securities professionals or all of
them were treated as one entity for such purpose) or by any other method of
allocation which does not take account of the equitable considerations re-

ferred to in this Section 8(d).  The amount paid or payable by an
indemnified party as a result of the losses, claims, damages or liabilities
(or actions in respect thereof) referred to above shall be deemed to
include any legal or other fees or expenses reasonably incurred by such
indemnified party in connection with investigating or defending any such
action or claim.  No person guilty of fraudulent misrepresentation (within
the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation.  The obligations of the Investors and any underwriters,
selling agents or other securities professionals in this Section 8(d) to
contribute shall be several in proportion to the number of shares of Common
Stock registered, underwritten, or sold as the case may be, by them and not
joint.

      (e)Notwithstanding any other provision of this Section 8, in no
event will (i) any Investor be required to undertake liability to any
person under this Section 8 for any amounts in excess of the dollar amount
of the proceeds to be received by the Investor from the sale of the
Investor's Registrable Securities (after deducting any fees, discounts and
commissions applicable thereto) pursuant to any registration statement
under which such Registrable Securities are to be registered under the
Securities Act and (ii) any underwriter, selling agent or other securities
professional be required to undertake liability to any person hereunder for
any amounts in excess of the discount, commission or other compensation
payable to such underwriter, selling agent or other securities professional
with respect to the Registrable Securities underwritten or sold by it.

      (f)The obligations of the Company under this Section 8 shall be in
addition to any liability which the Company may otherwise have to the
Investor, underwriter, selling agent or other securities professional
within the meaning of Section 15 of the Securities Act or Section 20 of the
Exchange Act, and the obligations of the Investor or other such person
under this Section 8 shall be in addition to any liability which the
Investor or other person may otherwise have to the Company, its directors,
officers who sign any registration statement with respect to the
Registrable Securities and each person, if any, who controls the Company
within the meaning of either Section 15 of the Securities Act or Section 20
<PAGE>
CUSIP No. 87612M108                                     Page 45 of 52 Pages

of the Exchange Act.  The remedies provided in this Section 8 are not
exclusive and shall not limit any rights or remedies which may otherwise be
available to an indemnified party at law or in equity.

      9.DELAY OF REGISTRATION

     No Investor shall have any right to obtain or seek an injunction
restraining or otherwise delaying any registration as the result of any
controversy that might arise with respect to the interpretation or
implementation of this Agreement.

      10.ASSIGNMENT OF REGISTRATION RIGHTS

     The rights to cause the Company to register Registrable Securities
pursuant to this Agreement may be assigned by an Investor to a transferee
or assignee of such securities who shall, upon such transfer or assignment,
be deemed an "Investor" under this Agreement; provided, however, that the
Company is, within a reasonable period of time after such transfer,
furnished with written notice of the name and address of such transferee or
assignee and the securities with respect to which such registration rights
are being assigned and such transferee or assignee assumes the transferor's
or assignor's obligations under this Agreement; provided, further, that
such assignment shall be effective only if immediately following such
transfer the further disposition of such securities by the transferee or
assignee is restricted under the Securities Act and that such transferee or
assignee is either (a) a partner or retired partner of any Investor that is
a partnership, (b) a member of the immediate family or a trust for the
benefit of any Investor that is an individual, (c) an entity controlling,
controlled by or under common control with any Investor that is not an
individual, or a limited partner, general partner or other affiliate of an
Investor, (d) a constituent member of any Investor that is a limited
liability company or (e) a transferee of at least 500,000 shares of Common
Stock (as adjusted for stock splits, stock dividends, stock consolidations
and the like).

      11."MARKET STAND-OFF" AGREEMENT

     The Investors hereby agree that they shall not, to the extent
requested by the Company and an underwriter of Common Stock (or other
securities) of the Company, sell or otherwise transfer or dispose (other
than to donees who agree to be similarly bound) of any Registrable
Securities for 90 days following the effective date of any registration
statement filed under the Securities Act in connection with an underwritten
public offering for the account of the Company; provided, however, that all
officers and directors of the Company (whether or not pursuant to this
Agreement) enter into similar agreements; provided, further, that the 
<PAGE>
CUSIP No. 87612M108                                     Page 46 of 52 Pages

foregoing provision shall not limit an Investor's right to participate in
such underwritten public offering in accordance with Section 4.2 hereof.

     In order to enforce the foregoing covenant, the Company may impose
stop-transfer instructions with respect to the Registrable Securities of
the Investors (and the shares or securities of every other person subject
to the foregoing restriction) until the end of such period.

     If as a result of the foregoing provisions of this Section 11 an
Investor is unable to sell any Registrable Securities proposed to be
registered pursuant to a registration statement previously filed in
accordance with Section 4.1 hereof, such registration is terminated prior
to the 60th day following the date on which such previously filed
registration statement initially became effective, and such Investor is not
permitted to sell such Registrable Securities in the Company's underwritten
public offering, then the registration statement previously filed in
accordance with Section 4.1 hereof shall not be counted as a registration
for the purposes of clauses (iii) and (iv) of Section 4.1 hereof.

      12.TERMINATION OF REGISTRATION RIGHTS

     The registration rights granted pursuant to this Agreement shall
terminate as to all Investors on the seventh anniversary of the Closing
Date.  In addition, such rights shall terminate as to any Investor when all
Registrable Securities of such Investor have been sold or distributed or
when all Registrable Securities of such Investor may be sold without
registration in reliance on Rule 144(k) under the Securities Act.

      13.BOARD REPRESENTATION AND VISITATION RIGHTS

      (a)GeneChem Management Inc. and SOFINOV Societe Financiere
d'Innovation Inc. (together, the "Designating Investors") will have the
right to designate one representative to the Company's Board of Directors
(such designee, the "Investor Designee"); provided, however, that the
Nominating Committee of the Company's Board of Directors may select, in its
sole discretion, an Investor Designee if the Designating Investors are
unable to agree upon such designee (i) in the case of an Investor Designee
to be elected at an annual meeting of the Company's shareholders, by
January 31 in the year of such meeting or (ii) in the case of an Investor
Designee to be appointed to fill a vacancy resulting from the resignation,
death or removal of the preceding Investor Designee, within 30 days
following such resignation, death or removal.  The Company shall use its
best efforts to nominate for election by its shareholders, to cause the
election of and thereafter to maintain in office the Investor Designee;
provided, however, that the foregoing shall not preclude the removal from
the Board of Directors of any Investor Designee to the extent required by
<PAGE>
CUSIP No. 87612M108                                     Page 47 of 52 Pages

applicable law or the Company's charter or bylaws.  The initial Investor
Designee will be a representative of GeneChem Management Inc. and will be
appointed to the Company's Board of Directors following the Company's 1998
annual meeting of shareholders.

      (b)Whichever of the Designating Investors does not have a
representative on the Company's Board of Directors will have the right to
designate a representative to attend all meetings of the Board of Directors
in a nonvoting observer capacity (provided that such representative
executes a confidentiality agreement reasonably satisfactory to the
Company) and, in this respect, the Company shall provide such
representative with copies of all notices, minutes, consents and other
material that it provides to its directors for all the meetings of the
Board of Directors.  Notwithstanding the foregoing, if the Company's Board
of Directors determines that the participation of such representative as to
any particular matter, whether due to a conflict of interest, a disclosure
of privileged information or otherwise, would be detrimental to the best
interests of the Company, then such representative shall be excluded from
receiving Board information or participating in the discussion by the Board
of Directors of such matter.

      (c)The provisions of this Section 13 will terminate as to either
Designating Investor as of the date on which such Designating Investor
(together with any person controlling, controlled by or under common
control with such Designating Investor) no longer holds at least 1,000,000
shares of Common Stock (as adjusted for stock splits, stock dividends,
stock consolidations and the like); such provisions shall not otherwise
terminate.

      14.INFORMATION RIGHTS

     The Company will deliver to such Investor each annual and quarterly
financial statements and other public information as is reasonably
requested by such Investor.  

      15.NOTICES

unenforceable under applicable law, such provision shall be excluded from
this Agreement, and the balance of this Agreement shall be interpreted as
if such provision were so excluded and shall be enforceable in accordance
with its terms.

      18.ENTIRE AGREEMENT; GOVERNING LAW

agreement between the parties with respect to the subject matter hereof and

1001 De Maisonneuve Blvd. West, Suite 920
Montreal, Quebec H3A 3C8

Dear Sirs:

     The undersigned understands that you and certain other investors (the
"Investors") propose to enter into a Common Stock and Warrant Purchase
Agreement (the "Purchase Agreement") providing for the purchase by the
Investors of shares (the "Shares") of common stock, par value $.01 per
share (the "Common Stock"), of Targeted Genetics Corporation (the
"Company") and warrants (the "Warrants") to purchase shares of Common Stock
(the "Warrant Shares") from the Company and that, following the purchase of
the Shares and Warrants, the Company will file a shelf registration
statement on Form S-3 (the "Registration Statement") with the Securities
and Exchange Commission (the "Commission") for the registration of the
transfer of the Shares and Warrant Shares by the Investors.

     In consideration of the purchase of the Shares and Warrants by the
Investors, and for other good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, the undersigned hereby
irrevocably agrees that, without the prior written consent of GeneChem
Technologies Venture Fund L.P., the undersigned will not, directly or
indirectly, sell, offer to sell, solicit an offer to buy, contract to sell
(including, without limitation, any short sale), grant any option to
purchase or right to acquire, acquire any option to dispose of, or
otherwise transfer or dispose of, any shares of Common Stock, or any
securities convertible into or exercisable or exchangeable for Common
Stock, for a period of 180 days after the closing date for the purchase of
the Shares and Warrants, except pursuant to the Registration Statement.

     The undersigned agrees that the provisions of this letter agreement
shall also be binding upon the successors, assigns, heirs and personal
representatives of the undersigned.

provisions thereof which survive termination) shall terminate or be
terminated prior to payment for the delivery of the Shares, you will
release us from our obligations under this letter agreement.  It is

the condition that Immunex Corporation ("Immunex") shall have executed and
delivered to you, not later than the date hereof, a letter agreement in
