       3.10 Company not an "Investment Company."  The Company has been
advised of the rules and requirements under the Investment Company Act of
1940, as amended (the "Investment Company Act").  The Company is not, and
immediately after receipt of payment for the Shares will not be, an

within the meaning of the Investment Company Act and shall conduct its
business in a manner so that it will not become subject to the Investment
Company Act.

the registration of the Common Stock under the Exchange Act or de-listing


                               Page 17 of 37



the Common Stock from the Nasdaq SmallCap Market, nor has the Company
received any notification that the SEC or the National Association of

that certain promissory note in the aggregate principal amount of three
million dollars ($3,000,000) issued in favor of Silicon Valley Bank, working
capital and general corporate purposes.
 
      3.13 Brokers and Finders.  No person or entity will have, as a result
of the transactions contemplated by this Agreement, any valid right,
interest or claim against or upon the Company or a Purchaser for any
commission, fee or other compensation pursuant to any agreement, arrangement
or understanding entered into by or on behalf of the Company, other than SG
Cowen & Co., LLC as lead agent.

       3.14 No Directed Selling Efforts or General Solicitation.  Neither
the Company nor any person or entity acting on its behalf has conducted any
general solicitation or general advertising (as those terms are used in
Regulation D) in connection with the offer or sale of any of the Securities.

       3.15 No Integrated Offering.  Neither the Company nor any of its
Affiliates, nor any person or entity acting on its or their behalf has,
directly or indirectly, made any offers or sales of any Company security or
solicited any offers to buy any security, under circumstances that would
adversely affect reliance by the Company on Section 4(2) for the exemption
from registration for the transactions contemplated hereby or would require
registration of the Securities under the Securities Act.

       3.16 Private Placement.  The offer and sale of the Securities to the
Purchasers as contemplated hereby is exempt from the registration
requirements of the Securities Act

       3.17 Internal Accounting Controls.  Except as described in the SEC

sufficient to provide reasonable assurance that (i) transactions are
executed in accordance with management's general or specific authorizations,
(ii) transactions are recorded as necessary to permit preparation of
financial statements in conformity with generally accepted accounting
principles, (iii) access to assets is permitted only in accordance with
management's general or specific authorization, and (iv) the recorded
accountability for assets is compared with the existing assets at reasonable
intervals and appropriate action is taken with respect to any differences.

              (a) "Intellectual Property" shall mean patents, trademarks,
service marks, trade names, copyrights, trade secrets, licenses, information
and other proprietary rights and processes. 

              (b) Except as disclosed in the SEC Documents and to the
knowledge of the Company, the Company owns or has the valid right to use all


                               Page 18 of 37

the Securities for any specified term; (ii) that future open market or other
transactions by any Purchaser, including short sales, and specifically
including, without limitation, short sales or "derivative" transactions,

control over any arm's length counter-party in any "derivative" transaction.
       
                              Article 4 

          REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE PURCHASERS

       Each Purchaser hereby severally, and not jointly, represents and
warrants to the Company on and as of the date hereof and on the applicable
Closing Date:
 
       4.1 Authorization.  Purchaser represents and warrants to the Company
that: (a) Purchaser has all requisite legal and corporate or other power and
capacity and has taken all requisite corporate or other action to execute
and deliver this Agreement, to purchase the Common Shares and the Warrants
to be purchased by it and to carry out and perform all of its obligations
under this Agreement; and (b) this Agreement constitutes the legal, valid
and binding obligation of such Purchaser, enforceable in accordance with its
terms, except (i) as limited by applicable bankruptcy, insolvency,


                               Page 20 of 37



reorganization or similar laws relating to or affecting the enforcement of
creditors' rights generally and (ii) as limited by equitable principles
generally.

       4.2 Investment Experience.  Purchaser is an "accredited investor" as
defined in Rule 501(a) under the Securities Act. Purchaser is aware of the
Company's business affairs and financial condition and has had access to and
has acquired sufficient information about the Company to reach an informed
and knowledgeable decision to acquire the Common Shares and the Warrants.
Purchaser has such business and financial experience as is required to give
it the capacity to protect its own interests in connection with the purchase
of the Common Shares and Warrants.

       4.3 Investment Intent.  Purchaser is purchasing the Common Shares and
the Warrants for its own account as principal, for investment purposes only,
and not with a present view to, or for, resale, distribution or
fractionalization thereof, in whole or in part, within the meaning of the
Securities Act, other than as contemplated by Article 7. Purchaser
understands that its acquisition of the Common Shares and the Warrants has
not been registered under the Securities Act or registered or qualified
under any state securities law in reliance on specific exemptions therefrom,
which exemptions may depend upon, among other things, the bona fide nature
of Purchaser's investment intent as expressed herein. Purchaser has
completed or caused to be completed the Purchaser Questionnaire attached
hereto as Exhibit C for use in preparation of the Registration Statement,
and the responses provided therein shall be true and correct as of the
applicable Closing Date and will be true and correct as of the effective
date of the Registration Statement. Purchaser, in connection with its
decision to purchase the Common Shares and the Warrants, has relied solely
upon the SEC Documents and the representations and warranties of the Company
contained herein. Purchaser will not, directly or indirectly, offer, sell,
pledge, transfer or otherwise dispose of (or solicit any offers to buy,
purchase or otherwise acquire or take a pledge of) any of the Securities
except in compliance with the Securities Act, and the rules and regulations
promulgated thereunder.

       4.4 Registration or Exemption Requirements.  Purchaser further
acknowledges and understands that the Securities may not be resold or
otherwise transferred except in a transaction registered under the
Securities Act or unless an exemption from such registration is available.

       4.5 Dispositions.  Purchaser will not, prior to the effectiveness of
the Registration Statement (as defined below), if then prohibited by law or
regulation: (a) sell, offer to sell, solicit offers to buy, dispose of,
loan, pledge or grant any right with respect to (collectively, a
"Disposition") the Securities; or (b) engage in any hedging or other
transaction which is designed or could reasonably be expected to lead to or
result in a Disposition of Securities by such Purchaser or an affiliate.  In
addition, Purchaser agrees that for so long as it owns any Common Shares, it
will not enter into any short sale of Shares executed at a time when the
Purchaser has no equivalent offsetting long position in the Common Shares.
For purposes of determining whether the Purchaser has an equivalent
offsetting long position in the  Common Shares, shares that the Purchaser is



                               Page 21 of 37




entitled to receive within sixty (60) days (whether pursuant to contract or
upon conversion or exercise of convertible securities) will be included as
if held long by the Purchaser.

       4.6 No Legal, Tax or Investment Advice.  Purchaser understands that
nothing in this Agreement or any other materials presented to Purchaser in
connection with the purchase and sale of the Common Shares and the Warrants
constitutes legal, tax or investment advice.  Purchaser has consulted such
legal, tax and investment advisors as it, in its sole discretion, has deemed
necessary or appropriate in connection with its purchase of the Common
Shares and the Warrants.

       4.7 Confidentiality.  Purchaser will hold in confidence all
information concerning this Agreement and the placement of the Securities
hereunder until the earlier of such time as (a) the Company has made a
public announcement concerning the Agreement and the placement of the
Securities hereunder or (b) this Agreement is terminated.

       4.8 Residency.  Purchaser's principal executive offices are in the
jurisdiction set forth immediately below Purchaser's name on the applicable
signature page attached hereto.

       4.9 Governmental Review.  Purchaser understands that no United States
federal or state agency or any other government or governmental agency has
passed upon or made any recommendation or endorsement of the Shares or the
Warrants.

       4.10 Legend.  Purchaser understands that, until such time as the
Registration Statement has been declared effective or the Securities may be
sold pursuant to Rule 144 under the Securities Act without any restriction
as to the number of securities as of a particular date that can then be
immediately sold, the Securities may bear a restrictive legend in
substantially the following form (and a stop transfer order may be placed
against transfer of the certificates for the Shares):

       "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES
LAWS OF ANY STATE OF THE UNITED STATES OR IN ANY OTHER JURISDICTION.  THE
SECURITIES REPRESENTED HEREBY MAY NOT BE OFFERED, SOLD OR TRANSFERRED IN THE
ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER
APPLICABLE SECURITIES LAWS UNLESS OFFERED, SOLD OR TRANSFERRED PURSUANT TO
AN AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THOSE LAWS."

              (a) The Company agrees that following the effectiveness of the
Registration Statement or at such time as such legend is no longer required
under this Section 4.10, it will, no later than three business days
following the delivery by an Purchaser to the Company or the Company's
transfer agent of a certificate representing Common Shares or Warrant
Shares, as applicable, issued with a restrictive legend and a signed and
completed notice of sale in substantially the form of Exhibit E attached
hereto (such third Trading Day, the "Legend Removal Date"), deliver or cause
to be delivered to such Purchaser a certificate representing such shares
that is free from any legend referring to the Securities Act.  The Company


                               Page 22 of 37




may not make any notation on its records or give instructions to any
transfer agent of the Company that enlarge the restrictions on transfer set
forth in this Section.  Certificates for Securities subject to legend
removal hereunder shall be transmitted by the transfer agent of the Company
to the Purchasers by crediting the account of the Purchaser's prime broker
with the Depository Trust Company System.  All costs and expenses related to
the removal of the legends and the reissuance of any Securities shall be
borne by the Company.

                      (b) In addition to such Purchaser's other available
remedies, the Company shall pay to a Purchaser, in cash, as partial
liquidated damages and not as a penalty, for each $1,000 of Common Shares
(or Warrant Shares underlying a Warrant tendered for legend removal) (based
on the VWAP of the Common Stock on the date such Securities are submitted to
the Company's transfer agent) delivered for removal of the restrictive
legend together with a signed and completed notice of sale in substantially
the form of Exhibit E attached hereto and subject to Section 4.10(a), $10
per Trading Day (increasing to $15 per Trading Day 5 Trading Days after such
damages have begun to accrue) for each Trading Day after the Legend Removal
Date until such certificate is delivered without a legend referring to the
Securities Act.  Nothing herein shall limit such Purchaser's right to pursue
actual damages for the Company's failure to deliver certificates
representing any Securities as required by the Agreement, and such Purchaser
shall have the right to pursue all remedies available to it at law or in
equity including, without limitation, a decree of specific performance
and/or injunctive relief, without the necessity of showing economic loss and
without any bond or other security being required..

                      (c) Each Purchaser, severally and not jointly with the
other Purchasers, agrees that the removal of the restrictive legend from
certificates representing Securities as set forth in this Section 4.10 is
predicated upon the Company's reliance that the Purchaser will sell any
Securities pursuant to either the registration requirements of the
Securities Act, including any applicable prospectus delivery requirements,
or an exemption therefrom.

       4.11 Foreign Investors.  If Purchaser is not a United States person
(as defined by Section 7701(a)(30) of the Internal Revenue Code of 1986, as
amended), Purchaser hereby represents that it has satisfied itself as to the
full observance of the laws of its jurisdiction in connection with any
invitation to subscribe for the Common Shares and the Warrants or any use of
this Agreement, including (a) the legal requirements within its jurisdiction
for the purchase of the Common Shares and the Warrants, (b) any foreign
exchange restrictions applicable to such purchase or acquisition, (c) any
government or other consents that may need to be obtained, and (d) the
income tax and other tax consequences, if any, that may be relevant to the
purchase, holding, redemption, sale or transfer of the Securities.
Purchaser's subscription and payment for and continued beneficial ownership
of the Securities will not violate any applicable securities or other laws
of Purchaser's jurisdiction.

execute a general consent to service of process in any jurisdiction;

              (f) upon notification by the SEC that that the Registration
Statement will not be reviewed or is no longer subject to further review and
comments by the SEC, the Company shall within five business days request
acceleration of such Registration Statement such that it becomes effective
at 5:00 p.m. New York Time on the date that effectiveness is requested (the
"Effective Date"); 

              (g)  deliver to each Purchaser, by 9:00 a.m. New York time on

purposes; and

                      (iv) of the existence of any fact and the happening of
any event that makes any statement of a material fact made in the

              (a) The Company agrees to indemnify and hold harmless each
Purchaser, the partners, members, officers and directors of each Purchaser

                               Page 28 of 37




and each person, if any, who controls such Purchaser within the meaning of
the Securities Act or the Exchange Act, from and against any losses, claims,
damages or liabilities to which they may become subject (under the
Securities Act or otherwise) insofar as such losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) arise out of, or
are based upon, any untrue statement or alleged untrue statement of a
material fact contained in the Registration Statement or any omission or
alleged omission to state therein 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 or arise out of any
failure by the Company to fulfill any undertaking included in the
Registration Statement and the Company will, as incurred, reimburse such
Purchaser, partner, member, officer, director or controlling person for any
legal or other expenses reasonably incurred in investigating, defending or
preparing to defend any such action, proceeding or claim; provided, however,
that the Company shall not be liable in any such case to the extent that
such loss, claim, damage or liability (collectively, "Loss") arises out of,
or is based upon, an untrue statement or omission or alleged untrue
statement or omission made in such Registration Statement in reliance upon
and in conformity with written information furnished to the Company by or on
behalf of such Purchaser, partner, member, officer, director or controlling
person specifically for use in preparation of the Registration Statement or
any breach of this Agreement by such Purchaser; and provided further,
however, that the Company shall not be liable to any Purchaser of
Registrable Shares (or any partner, member, officer, director or controlling
person of such Purchaser) to the extent that any such Loss is caused by an
untrue statement or omission or alleged untrue statement or omission made in
any preliminary prospectus if either (i)(A) such Purchaser failed to send or
deliver a copy of the final prospectus with or prior to the delivery of
written confirmation of the sale by such Purchaser to the person asserting
the claim from which such Loss resulted and (B) the final prospectus
corrected such untrue statement or omission, (ii) (X) such untrue statement
or omission is corrected in an amendment or supplement to the prospectus and
(Y) having previously been furnished by or on behalf of the Company with
copies of the prospectus as so amended or supplemented, such Purchaser
thereafter fails to deliver such prospectus as so amended or supplemented,
with or prior to the delivery of written confirmation of the sale of a
Registrable Share to the person asserting the claim from which such Loss
resulted or (iii) such Purchaser sold Registrable Shares in violation of
such Purchaser's covenant contained in Section 7.5 of this Agreement.

              (b) Each Purchaser, severally and not jointly, agrees to
indemnify and hold harmless the Company (and each person, if any, who
controls the Company within the meaning of Section 15 of the Securities Act
or Section 20 of the Exchange Act, each officer of the Company who signs the
Registration Statement and each director of the Company), from and against
any losses, claims, damages or liabilities to which the Company (or any such
officer, director or controlling person) may become subject (under the
Securities Act or otherwise), insofar as such losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) arise out of, or
are based upon, any breach of this Agreement by such Purchaser or any untrue
statement or alleged untrue statement of a material fact contained in the
Registration Statement or any omission or alleged omission to state therein


                               Page 29 of 37



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 in each case, on the effective date thereof, if, and to
the extent, such untrue statement or omission or alleged untrue statement or
omission was made in reliance upon and in conformity with written
information furnished by or on behalf of such Purchaser specifically for use
in preparation of the Registration Statement, and such Purchaser will
reimburse the Company (and each of its officers, directors or controlling
persons) for any legal or other expenses reasonably incurred in
investigating, defending or preparing to defend any such action, proceeding
or claim;  provided, however, that in no event shall any indemnity under
this Section 7.4(b) be greater in amount than the dollar amount of the
proceeds (net of the amount of any damages such Purchaser has otherwise been
required to pay by reason of such untrue statement or omission or alleged
untrue statement or omission) received by such Purchaser upon the sale of
the Registrable Securities included in the Registration Statement giving
rise to such indemnification obligation.

              (c) Promptly after receipt by any indemnified person of a
notice of a claim or the beginning of any action in respect of which
indemnity is to be sought against an indemnifying person pursuant to this
Section 7.4, such indemnified person shall notify the indemnifying person in
writing of such claim or of the commencement of such action, and, subject to
the provisions hereinafter stated, in case any such action shall be brought
against an indemnified person and such indemnifying person shall have been
notified thereof, such indemnifying person shall be entitled to participate
therein, and, to the extent that it shall wish, to assume the defense
thereof, with counsel reasonably satisfactory to such indemnified person.
After notice from the indemnifying person to such indemnified person of its
election to assume the defense thereof, such indemnifying person shall not
be liable to such indemnified person for any legal expenses subsequently
incurred by such indemnified person in connection with the defense thereof;
provided, however, that if there exists or shall exist a conflict of
interest that would make it inappropriate in the reasonable judgment of the
indemnified person for the same counsel to represent both the indemnified
person and such indemnifying person or any affiliate or associate thereof,
the indemnified person shall be entitled to retain its own counsel at the
expense of such indemnifying person; provided, further, that no indemnifying
person shall be responsible for the fees and expense of more than one
separate counsel for all indemnified parties. The indemnifying party shall
not settle an action without the consent of the indemnified party, which
consent shall not be unreasonably withheld.

              (d) If after proper notice of a claim or the commencement of
any action against the indemnified party, the indemnifying party does not
choose to participate, then the indemnified party shall assume the defense
thereof and upon written notice by the indemnified party requesting advance
payment of a stated amount for its reasonable defense costs and expenses,
the indemnifying party shall advance payment for such reasonable defense
costs and expenses (the "Advance Indemnification Payment") to the
indemnified party.  In the event that the indemnified party's actual defense
costs and expenses exceed the amount of the Advance Indemnification Payment,
then upon written request by the indemnified party, the indemnifying party
shall reimburse the indemnified party for such difference; in the event that


                               Page 30 of 37




the Advance Indemnification Payment exceeds the indemnified party's actual
costs and expenses, the indemnified party shall promptly remit payment of
such difference to the indemnifying party.

              (e) If the indemnification provided for in this Section 7.4 is
held by a court of competent jurisdiction to be unavailable to an
indemnified party with respect to any losses, claims, damages or liabilities
referred to herein, the indemnifying party, in lieu of indemnifying such
indemnified party thereunder, shall to the extent permitted by applicable
law contribute to the amount paid or payable by such indemnified party as a
result of such loss, claim, damage or liability in such proportion as is
appropriate to reflect the relative fault of the indemnifying party on the
one hand and of the indemnified party on the other, as well as any other
relevant equitable considerations; provided, that in no event shall any
contribution by an indemnifying party hereunder be greater in amount than
the dollar amount of the proceeds (net of the amount of any damages such
indemnifying party has otherwise been required to pay by reason of such
untrue statement or omission or alleged untrue statement or omission)
received by such indemnifying party upon the sale of the Registrable
Securities included in the Registration Statement giving rise to such
indemnification obligation.

       7.4 Prospectus Delivery.  Each Purchaser hereby covenants with the
Company not to make any sale of the Registrable Shares without complying
with Section 8.3.  The Purchaser acknowledges that there may be times when
the Company must suspend the use of the prospectus forming a part of the
Registration Statement until such time as an amendment to the Registration
Statement has been filed by the Company and declared effective by the SEC,
or until such time as the Company has filed an appropriate report with the
SEC pursuant to the Exchange Act.  The Purchaser hereby covenants that it
will not sell any Registrable Shares pursuant to said prospectus during the
period commencing at the time at which the Company gives the Purchaser
notice of the suspension of the use of said prospectus and ending at the
time the Company gives the Purchaser notice that the Purchaser may
thereafter effect sales pursuant to said prospectus; provided that such
suspension periods shall in no event exceed thirty (30) days in any twelve
(12) month period and that, in the good faith judgment of the Company's
Board of Directors, the Company would, in the absence of such delay or
suspension hereunder, be required under state or federal securities laws to
disclose any corporate development, a potentially significant transaction or
event involving the Company, or any negotiations, discussions, or proposals
directly relating thereto, in either case the disclosure of which would
reasonably be expected to have a material adverse effect upon the Company or
its stockholders; provided further, that the Company may suspend the use of
the prospectus forming a part of the Registration Statement to the extent
necessary to file any post-effective amendment to the Registration Statement
in order to amend the table of selling stockholders within the Registration
Statement to reflect transfers of the Securities pursuant to Sections 8.3(a)
and 8.3(b).  If, after the Registration Statement has been declared
effective by the SEC, sales cannot be made pursuant to such Registration
Statement, except as excused pursuant to this Section 7.4, then the Company
will make pro rata payments to each Holder, as liquidated damages and not as
a penalty, in an amount equal to one (1%) of the aggregate amount invested


                               Page 31 of 37




by such Holder (the amount invested by a Holder shall include the purchase
price of the Shares acquired by such Holder and shall exclude any amount
attributable to the Warrants acquired by such Holder pursuant to the
Purchase Agreement) for each thirty (30) day period following the date sales
cannot be made pursuant to such Registration Statement after it has been
declared effective.

       7.5 Termination of Obligations.  The obligations of the Company
pursuant to Section 7.2 hereof shall cease and terminate upon the earlier to
occur of (a) such time as all of the Registrable Shares have been resold,
(b) such time as all of the Registrable Shares may be resold in a three
month period pursuant to Rule 144(k), or (c) the fifth anniversary of later
of the First Closing Date or Second Closing Date.

       7.6 Reporting Requirements.

              (a) With a view to making available the benefits of certain
rules and regulations of the SEC that may at any time permit the sale of the
Securities to the public without registration or pursuant to a registration
statement on Form S-3, the Company agrees to use its best efforts to:

                      (i) make and keep public information available, as
those terms are understood and defined in Rule 144 under the Securities Act;

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

                      (iii) so long as any of the Purchasers own Registrable
Shares, to furnish to such Purchaser upon request (A) a written statement by
the Company as to whether it is in compliance with the reporting
requirements of Rule 144, the Securities Act and the Exchange Act, or
whether it is qualified as a registrant whose securities may be resold
pursuant to SEC Form S-3, and (B) a copy of the most recent annual or
quarterly report of the Company and such other reports and documents so
filed by the Company.

       7.7 Blue Sky.  The Company shall obtain and maintain all necessary
blue sky law permits and qualifications, or secured exemptions therefrom,
required by any state for the offer and sale of Securities.

       7.8 Stockholder Approval.  Promptly following the First Closing Date,
the Company shall take all action necessary to call the annual meeting of
its stockholders (the "Annual Stockholders Meeting") and seek the approval
of the Company's stockholders for, among other matters, the authorization
and issuance of the Common Shares and Warrants at the Second Closing and the
issuance of the Warrant Shares upon exercise of such Warrants in compliance
with Rule 4350(i) of the Marketplace Rules of the NASD (the "Stockholder
Approval"), to the extent required by The Nasdaq Stockmarket, Inc.  In
connection therewith, the Company will promptly prepare and file with the
SEC proxy materials (including a proxy statement and form of proxy) for use
at the Annual Stockholders Meeting and, promptly after receiving clearance



                               Page 32 of 37




from the SEC, shall promptly mail such proxy materials to the stockholders
of the Company.

       7.9 Publicity.  The Company shall, on or before 9:30 a.m. New York
City time on the first business day following the date hereof, issue a press

hereby.

                      (i) in accordance with the Registration Statement, in
which case Purchaser covenants to comply with the requirement of delivering
a current prospectus; or

                      (ii) in accordance with Rule 144, in which case
Purchaser covenants to comply with Rule 144; or

                      (iii) (A) If the transferee has agreed in writing to
be bound by the terms of this Agreement, (B) such Purchaser shall have
notified the Company of the proposed disposition and shall have furnished
the Company with a detailed statement of the circumstances surrounding the

require registration of such shares under the Securities Act.

              (b) Notwithstanding the provisions of subsection (a) above, no
such restriction shall apply to a transfer by a Purchaser that is (i) a

that in each case the transferee will agree in writing to be subject to the
terms of this Agreement to the same extent as if he were an original
Purchaser hereunder.

              (c) Purchaser further acknowledges and agrees that, if a
Purchaser is selling the Securities using the prospectus forming a part of
the Registration Statement, such Securities are not transferable on the
books of the Company unless the certificate evidencing such Securities is
submitted to the Company's transfer agent and a separate certificate
executed by an officer of, or other person duly authorized by, the Purchaser
in the form attached hereto as Exhibit E is submitted to Cooley Godward.

       8.4 Purchaser Information.  Each Purchaser covenants that it will
promptly notify the Company of any changes in the information set forth in

"Plan of Distribution.

       8.5 Material Non-Public Information.  Except with respect to those
Purchasers listed on Schedule 5.5 hereof, the Company covenants and agrees

of the Common Shares and the Warrants abandoned at any time prior to the
