the Company as follows:

                                       2
<PAGE>

          a.   Without limiting Buyer's right to sell the Common Stock pursuant
to the Registration Statement (as that term is defined in the Registration
Rights Agreement defined below), the Buyer is purchasing the Preferred Stock and
will be acquiring the shares of Common Stock issuable upon conversion of the
Preferred Stock (the "Converted Shares") for its own account for investment, and
not with a view towards the public sale or distribution thereof and not with a
view to or for sale in connection with any distribution thereof.

          b.   The Buyer is (i) an "accredited investor" as that term is defined
in Rule 501 of the General Rules and Regulations under the 1933 Act by reason of
Rule 501(a)(3), (ii) experienced in making investments of the kind described in
this Agreement and the related documents, (iii) able, by reason of the business
and financial experience of its officers (if an entity) and professional
advisors (who are not affiliated with or compensated in any way by the Company
or any of its affiliates or selling agents), to protect its own interests in
connection with the transactions described in this Agreement, and the related
documents, and (iv) able to afford the entire loss of its investment in the
Securities.

          c.   All subsequent offers and sales of the Preferred Stock and the
shares of Common Stock representing the Converted Shares (such Common Stock
sometimes referred to as the "Shares") by the Buyer shall be made pursuant to
registration of the Shares under the 1933 Act or pursuant to an exemption from
registration.

          d.   The Buyer understands that the Preferred Stock are being offered
and sold to it in reliance on specific exemptions from the registration
requirements of United States federal and state securities laws and that the
Company is relying upon the truth and accuracy of, and the Buyer's compliance
with, the representations, warranties, agreements, acknowledgments and
understandings of the Buyer set forth herein in order to determine the
availability of such exemptions and the eligibility of the Buyer to acquire the
Preferred Stock.

          e.   The Buyer and its advisors, if any, have been furnished with all
materials relating to the business, finances and operations of the Company and
materials relating to the offer and sale of the Preferred Stock and the offer of
the Shares which have been requested by the Buyer, including Annex V hereto. The
Buyer and its advisors, if any, have been afforded the opportunity to ask
questions of the Company and have received complete and satisfactory answers to
any such inquiries.  Without limiting the generality of the foregoing, the Buyer
has also had the opportunity to obtain and to review (i) the Company's annual
report on Form 10-KSB for the year ending December 31, 1998, (ii) the Company's
reports on Form 10-QSB for the periods ending March 31, 1999, June 30, 1999 and
September 30, 1999 (the  "SEC Reports");

          f.   The Buyer understands that its investment in the Securities
involves a high degree of risk.

                                       3
<PAGE>

          g.   The Buyer understands that no United States federal or state
agency or any other government or governmental agency has passed on or made any
recommendation or endorsement of the Securities.

          h.   This Agreement has been duly and validly authorized, executed and
delivered on behalf of the Buyer and is a valid and binding agreement of the
Buyer enforceable in accordance with its terms, subject as to enforceability to
general principles of equity and to bankruptcy, insolvency, moratorium and other
similar laws affecting the enforcement of creditors' rights generally.

          i.   Notwithstanding the provisions hereof or of the Preferred Stock,
in no event (except with respect to an automatic conversion of the Preferred
Stock as provided in the Certificate of Designations) shall each Buyer be
entitled to convert any Preferred Stock to the extent that, after such
conversion, the sum of (1) the number of shares of Common Stock beneficially
owned by such Buyer and its affiliates (other than shares of Common Stock which
may be deemed beneficially owned through the ownership of the unconverted
portion of the Preferred Stock), and (2) the number of shares of Common Stock
issuable upon the conversion of the Preferred Stock with respect to which the
determination of this proviso is being made, would result in beneficial
ownership by such Buyer and its affiliates of more than 4.99% of the outstanding
shares of Common Stock. For purposes of the proviso to the immediately preceding
sentence, beneficial ownership shall be determined in accordance with Section
13(d) of the Securities Exchange Act of 1934, as amended (the "1934 Act"). Any
issuance by the Company to the Buyer in excess of the limit contained in this
Paragraph 3.i. shall be null and void, ab initio, and upon notice of such
invalid issuance, the Company shall correct its books and cause its transfer
agent's books to be corrected forthwith to reflect that the Buyer's ownership of
Common Stock is within the limit set forth herein. Buyer shall immediately
deliver any certificates for invalidly issued Common Stock to the Company's
transfer agent. The Company further agrees to (i) immediately reissue
certificates for Common Stock to the extent that a portion of the Common Stock
represented by said certificates have been validly issued and (ii) immediately
reissue all or a portion of those shares which were deemed invalidly issued (at
a price set forth in the original conversion notices applicable to such shares)
upon notice from the Buyer that the reissuance of such shares would not cause
such Buyer to have a beneficial ownership interest in excess of 4.99%. The
Company hereby indemnifies and holds each Buyer free and harmless in connection
with any and all liabilities, losses, costs and expenses, including, without
limitation, attorneys' fees and costs arising from or relating to claims made by
any third parties with respect to any and all purported violations by each Buyer
under Sections 13(d) and 16 resulting from a conversion(s) of Preferred Stock,
unless such claim arises from such Buyer's default of its obligations hereunder,
or representations or warranties contained herein. Buyer agrees that it shall
not knowingly attempt to convert that number of shares of Common Stock that
would cause it to own beneficially an amount greater than 4.99% of the Common
Stock.

          j. Buyer represents that it neither is nor will be obligated for any
finders' fee or commission nor is it aware of any such fee or commission payable
in connection with this transaction other than as set forth on the Joint Escrow
Instructions (attached hereto as Annex II).  Buyer agrees to indemnify and to
hold harmless the Company from any liability for any

                                       4
<PAGE>

commission or compensation in the nature of a finders' fee (and the costs and
expenses of defending against such liability or asserted liability) for which
such Buyer or any of its officers, partners, employees, or representatives is
responsible.

          3.   COMPANY REPRESENTATIONS, ETC.

          The Company represents and warrants and hereby covenants and agrees
with each Buyer that:

          a.   Concerning the Preferred Stock and the Shares. The Preferred
Stock has been duly authorized and, when issued, will be duly and validly
issued, fully paid and non-assessable and will not subject the holder thereof to
personal liability by reason of being such holder. There are no preemptive
rights of any stockholder of the Company, as such, to acquire the Preferred
Stock or the Shares.

          b.   Reporting Company Status. The Company is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Minnesota and has the requisite corporate power to own its properties and to
carry on its business as now being conducted. The Company is duly qualified as a
foreign corporation to do business and is in good standing in each jurisdiction
where the nature of the business conducted or property owned by it makes such
qualification necessary, other than those jurisdictions in which the failure to
so qualify would not have a material adverse effect on the business, operations
or prospects or condition (financial or otherwise) of the Company and its
subsidiaries, taken as a whole. The Company has registered its Common Stock
pursuant to Section 12 of the 1934 Act, and the Common Stock is listed and
traded on the NASDAQ "Bulletin Board" market. The Company has received no
notice, either oral or written, with respect to the continued eligibility of the
Common Stock for such listing, and the Company has maintained all requirements
for the continuation of such listing.

          c.   Authorized Shares. The Company has at November 15, 1999,
4,823,187 shares of Common Stock outstanding, and has sufficient authorized and
unissued Shares as may be reasonably necessary to effect the conversion of the
Preferred Stock (assuming all future conversions occurred are based upon an
average 5-day closing bid of the Common Stock, as reported by Bloomberg, LP
which was one-half (1/2) of the closing bid price of the Common Stock on the
Closing Date [the "Closing Date Bid"]) and exercise of the Warrants (as defined
in Section 4.j.) at the Closing Date Bid. The Common Stock has been duly
authorized and, when issued upon conversion of the Preferred Stock in accordance
with its terms, will be duly and validly issued, fully paid and non-assessable
and will not subject the holder thereof to personal liability by reason of being
such holder.

          d.   Securities Purchase Agreement; Registration Rights Agreement and
Stock. This Agreement and the Registration Rights Agreement, the form of which
is attached hereto as Annex IV (the "Registration Rights Agreement"), and the
transactions contemplated hereby and thereby, have been duly and validly
authorized by the Company, this Agreement has been duly

                                       5
<PAGE>

executed and delivered by the Company and this Agreement is, and the Preferred
Stock, and the Registration Rights Agreement, when executed and delivered by or
on behalf of the Company, will be, valid and binding agreements of the Company
enforceable in accordance with their respective terms, subject, as to
enforceability, to general principles of equity and to bankruptcy, insolvency,
moratorium, and other similar laws affecting the enforcement of creditors'
rights generally.

          e.   Non-contravention. The execution and delivery of this Agreement
and the Registration Rights Agreement by the Company, the issuance of the
Securities, and the consummation by the Company of the other transactions
contemplated by this Agreement, the Registration Rights Agreement, and the
Preferred Stock do not and will not conflict with or result in a breach by the
Company of any of the terms or provisions of, or constitute a default under (i)
the articles of incorporation or by-laws of the Company, each as currently in
effect, (ii) except as disclosed in Annex V, any indenture, mortgage, deed of
trust, or other material agreement or instrument to which the Company is a party
or by which it or any of its properties or assets are bound, including any
listing agreement for the Common Stock (except as herein set forth), (iii) to
its knowledge, any existing applicable law, rule, or regulation or any
applicable decree, judgment, or order of any court, United States federal or
state regulatory body, administrative agency, or other governmental body having
jurisdiction over the Company or any of its properties or assets, or (iv) any
listing agreement for its Common Stock, except such conflict, breach or default
which would not have a material adverse effect on the transactions contemplated
herein.

          f.   Approvals. No authorization, approval or consent of any court,
governmental body, regulatory agency, self-regulatory organization, or stock
exchange or market or the stockholders of the Company is required to be obtained
by the Company for the issuance and sale of the Securities to the Buyer as
contemplated by this Agreement, except such authorizations, approvals and
consents that have been obtained.

          g.   SEC Filings. None of the Company's SEC Reports contained, at the
time they were filed, any untrue statement of a material fact or omit to state
any material fact required to be stated therein or necessary to make the
statements made therein in light of the circumstances under which they were
made, not misleading, except as corrected by an amended filing made prior to the
date hereof. Except as set forth on Annex V hereto, the Company has since June
1997 timely filed all requisite forms, reports and exhibits thereto with the
SEC.,

          h.   Absence of Certain Changes. Since December 31, 1998 there has
been no material adverse change and no material adverse development in the

material liabilities (absolute or contingent) except liabilities incurred in the
ordinary course of business consistent with past practices; (ii) discharged or

redeemed, or made any agreements to purchase or redeem, any shares of its
capital stock; (iv) sold, assigned or transferred any other tangible assets, or

any rights of material value, whether or not in the ordinary course of business,

changes in employee compensation, except in the ordinary course of business
consistent with past practices; or (vii) experienced any material problems with
labor or management in connection with the terms and conditions of their
employment.

          i.   Full Disclosure. There is no fact known to the Company (other
than general economic conditions known to the public generally or as disclosed
in the Company's SEC Reports), that has not been disclosed in writing to the
Buyer that (i) would reasonably be expected to have a material adverse effect on
the business or financial condition of the Company or (ii) would reasonably be
expected to materially and adversely affect the ability of the Company to
perform its obligations pursuant to this Agreement or any of the agreements
contemplated hereby (collectively, including this Agreement, the "Transaction
Agreements").

          j.   Absence of Litigation. Except as set forth in Annex V hereto, and
in the Company's SEC Reports, which the Buyer has reviewed, there is no action,
suit, proceeding, inquiry or investigation before or by any court, public board
or body pending or, to the knowledge of the Company, threatened against or
affecting the Company, wherein an unfavorable decision, ruling or finding would
have a material adverse effect on the properties, business or financial
condition. results of operation or prospects of the Company and its subsidiaries
taken as a whole or the transactions contemplated by any of the Transaction
Agreements or which would adversely affect the validity or enforceability of, or
the authority or ability of the Company to perform its obligations under, any of
the Transaction Agreements.

          k.   Absence of Events of Default. Except as set forth in Annex V
hereto or the Company's SEC Reports, no Event of Default (or its equivalent
term), as defined in the respective agreement to which the Company is a party,
and no event which, with the giving of notice or the passage of time or both,
would become an Event of Default (or its equivalent term) (as so defined in such
agreement), has occurred and is continuing, which would have a material adverse
effect on the Company's financial condition or results of operations.

          l.   Prior Issues. Except as set forth in Annex V or the Company's SEC
Reports, during the twelve (12) months preceding the date hereof, the Company
has not issued any Common Stock or convertible securities in capital
transactions which have not been fully disclosed in the Company's filings with
the SEC. Except as set forth in Annex V, all such issuances (except for
issuances to Buyer) have been fully converted into shares of common stock and
there are no outstanding unconverted debt or convertible securities from those
transactions.

          m.   No Undisclosed Liabilities or Events. Except as set forth in
Annex V, the Company has no liabilities or obligations other than those
disclosed in the Company's SEC Reports

                                       7
<PAGE>

or those incurred in the ordinary course of the Company's business since
December 31, 1998, and which, individually or in the aggregate, do not or would
not have a material adverse effect on the properties, business, condition
(financial or otherwise), results of operations or prospects of the Company and
its subsidiaries, taken as a whole. No event or circumstances has occurred or
exists with respect to the Company or its properties, business, condition
(financial or otherwise), results of operations or prospects, which, under
applicable law, rule or regulation, requires public disclosure or announcement

contained in any indenture, mortgage, deed of trust or other material instrument

affiliates nor any person acting on its or their behalf has, directly or
indirectly, made any offer or sales of any security or solicited any offers to
buy any security under circumstances that would eliminate the availability of
the exemption from registration under Regulation D in connection with the offer
and sale of the Securities as contemplated hereby.

          p.   Dilution.  The number of Shares issuable upon conversion of the
Preferred Stock may increase substantially in certain circumstances, including,
but not necessarily limited to, the circumstance wherein the trading price of
the Common Stock declines prior to the conversion of the Preferred Stock.  The
Company's executive officers and directors have studied and fully understand the
nature of the Securities being sold hereby and recognize that they have a
potential dilutive effect.  The board of directors of the Company has concluded
that, in its good faith business judgment, such issuance is in the best
interests of the Company.  The Company specifically acknowledges that its
obligation to issue the Shares upon conversion of the Preferred Stock is binding
upon the Company and enforceable regardless of the dilution such issuance may
have on the ownership interests of other shareholders of the Company.

          q.   Acknowledgment by Company.  Company represents and warrants that
neither the Buyer, nor any persons or entities representing or purporting to
represent the Buyer have made any representation or warranty which is not
contained expressly in this Agreement or any other agreements referred to
herein.  Without limiting the foregoing, Company specifically acknowledges that
the Buyer has made no representations that it is a "long term" investor in the
Company, or that it intends to hold the Preferred Stock or shares of stock in
the Company (obtained by conversions of the Preferred Stock) for any period
beyond that which is required under the Securities Act.    Company further
acknowledges that the Buyer may hedge the shares of stock in the Company prior
to or after the conversions of any of the Preferred Stock, provided that such
hedging is done in compliance with the Securities Act, Securities Exchange Act,
any rules applicable to securities traded on the NASDAQ "Bulletin Board" and the
express terms of this Agreement, the Certificate of Designation for the
Preferred Stock and the Registration Rights Agreement.  Notwithstanding the

                                       8
<PAGE>

foregoing, provided that the Company has not defaulted hereunder or under any
other agreement entered into in connection herewith (including, without
limitation, the Registration Rights Agreement and the Certificate of Designation
for the Preferred Stock, both dated the date hereof), each Buyer acting
individually shall not "short" (as such term is defined by the Securities Act)
shares of Common Stock (calculated pursuant hereto at the time such shares of
Common Stock are shorted) in excess of twenty percent (20%) of the sum of (i)
the aggregate number of shares of Common Stock the Buyer would receive if all of
the shares of Preferred Stock (then held by such Buyer) were converted by Buyer
on the day of the "short" sale, plus (ii) the number of shares of Common Shares
held by (or deliverable to) such Buyer on the day of the "short sale" as a
result of prior conversions.

          r.   Brokers Fee.  The Company represents that it neither is nor will
be obligated for any finders' fee or commission nor is it aware of any such fee
or commission payable in connection with this transaction other than as set
forth on the Joint Escrow Instructions (attached hereto as Annex II).  The
Company agrees to indemnify and to hold harmless the Buyer from any liability
for any commission or compensation in the nature of a finders' fee (and the
costs and expenses of defending against such liability or asserted liability)
for which the Company or any of its officers, partners, employees, or
representatives is responsible.

          4.   CERTAIN COVENANTS AND ACKNOWLEDGMENTS.

          a.   Transfer Restrictions.  The Buyer acknowledges that (1) the
Preferred Stock has not been and is not being registered under the provisions of
the 1933 Act and, except as provided in the Registration Rights Agreement, the
Shares have not been and are not being registered under the 1933 Act, and may
not be transferred unless (A) subsequently registered thereunder or (B) the
Buyer shall have delivered to the Company an opinion of counsel, reasonably
satisfactory in form, scope and substance to the Company, to the effect that the
Securities to be sold or transferred may be sold or transferred pursuant to an
exemption from such registration; (2) any sale of the Securities made in
reliance on Rule 144 promulgated under the 1933 Act may be made only in
accordance with the terms of said Rule and further, if said Rule is not
applicable, any resale of such Securities under circumstances in which the
seller, or the person through whom the sale is made, may be deemed to be an
underwriter, as that term is used in the 1933 Act, may require compliance with
some other exemption under the 1933 Act or the rules and regulations of the SEC
thereunder; and (3) neither the Company nor any other person is under any
obligation to register the Securities (other than pursuant to the Registration
Rights Agreement) under the 1933 Act or to comply with the terms and conditions
of any exemption thereunder.

          b.   Restrictive Legend.  The Buyer acknowledges and agrees that the
Preferred Stock and, until such time as the Common Stock has been registered
under the 1933 Act as contemplated by the Registration Rights Agreement and sold
pursuant to an effective Registration Statement, certificates and other
instruments representing any of the Securities shall bear a restrictive legend
in substantially the following form (and a stop-transfer order may be placed
against transfer of any such Securities):

                                       9
<PAGE>

          THESE SECURITIES (THE "SECURITIES") HAVE NOT BEEN REGISTERED UNDER THE
          SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR THE
          SECURITIES LAWS OF ANY STATE AND MAY NOT BE SOLD OR OFFERED FOR SALE
          IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE
          SECURITIES OR AN OPINION OF COUNSEL OR OTHER EVIDENCE ACCEPTABLE TO
          THE CORPORATION THAT SUCH REGISTRATION IS NOT REQUIRED.

          c.   Registration Rights Agreement.  The parties hereto agree to enter
into the Registration Rights Agreement on or before the Closing Date.

          d.   Filings.  The Company undertakes and agrees to make all necessary
filings in connection with the sale of the Preferred Stock to the Buyer under
any United States laws and regulations, or by any domestic securities exchange
or trading market, and to provide a copy thereof to the Buyer promptly after
such filing.

          e.   Reporting Status.  So long as the Buyer beneficially owns any of
the Preferred Stock, the Company shall file all reports required to be filed
with the SEC pursuant to Section 13 or 15(d) of the 1934 Act, and the Company
shall not terminate its status as an issuer required to file reports under the
1934 Act even if the 1934 Act or the rules and regulations thereunder would
permit such termination.

          f.   Use of Proceeds.  The Company will use the proceeds from the sale
of the Preferred Stock (excluding amounts paid by the Company for legal fees,
finder's fees and escrow agent fees in connection with the sale of the Preferred
Stock) for general capital purposes and, without limiting the foregoing, shall
not, directly or indirectly, use any of such proceeds for investment in any
other affiliate.

          g.   Future Purchases.  Intentionally deleted.

          h.   Certain Agreements.  (i) The Company covenants and agrees that it
will not, without the prior written consent of the Buyer, enter into any
subsequent or further offer or sale of Common Stock or securities convertible
into Common Stock with any third party until one hundred eighty (180) days after
the Effective Date (as defined below).

          (ii)   The provisions of subparagraph (h)(i) will not apply to (w)
Common Stock issued as "restricted stock" as defined in SEC Rule 144, provided
the holder thereof holds such Common Stock for at least one year from the date
of issuance; (x) a secondary public offering of  shares of Common Stock at
market; (y) an offering of convertible debentures at market or above; or (z) the
issuance of securities (other than for cash) in connection with a merger,
consolidation, sale of assets, disposition or the exchange of the capital stock
for assets, stock or other joint venture interests; provided, such securities
would not be included in the Registration Statement relating to

                                       10
<PAGE>

the Shares and a registration statement in respect of such stock shall not be
filed prior to sixty (60) days after the Effective Date.

          (iii)   The term "Effective Date" means the effective date of the
Registration Statement covering the Registrable Securities (as defined in the
Registration Rights Agreement).

          (iv)    In the event the Company breaches the provisions of this
Paragraph 4(h), the Conversion Price shall be amended to be the lesser of (I)
70% of the average of the three (3) lowest closing bid prices (not necessarily
consecutive) during the fifteen (15) day trading period immediately prior to the
Conversion Date, (II) $5.125 [the lowest closing bid price during the ten (10)
day trading period immediately prior to the Closing Date], and Buyer may, within
thirty (30) days after it receives written notice of such breach from the
Company, require the Company to immediately redeem all outstanding Preferred
Stock in accordance with Section 4(k)(y).

          i.   Available Shares.  The Company shall have at all times authorized
and reserved for issuance, free from preemptive rights, shares of Common Stock
equal to two hundred percent (200%) of the number of shares of Common Stock
issuable upon conversion of all of the outstanding Preferred Stock, and the
exercise of the Warrants (as defined below).

          j.       Warrants.    The Company agrees to issue to Buyer at the
Closing, transferable divisible warrants with cashless exercise provisions (the
"Warrants") for 50,000 shares of Common Stock.  Such Warrants shall bear an
exercise price equal to the Closing Bid price of the Company's common stock on
the Closing Date, and shall be exercisable immediately upon issuance, and for a
period of five (5) years thereafter, in the form annexed hereto as Annex VI,
together with piggy-back registration rights, and demand registration rights
under the Registration Rights Agreement.

          k.   Limitation on Issuance of Shares.  The Certificate of Designation
for the Preferred Stock shall provide that the Company shall take all steps
reasonably necessary to be in a position to issue shares of Common Stock on
conversion of the Preferred Stock without violating the "Cap Regulations".  If
despite taking such steps, the Company is limited in the number of shares of
Common Stock it may issue by the "Cap Regulations," to the extent that the
Company cannot issue such shares of Common Stock, due upon a Notice of
Conversion, without violating the Cap Regulations, the Company shall immediately
notify Buyer the number of shares of the Preferred Stock which are not
convertible as a result of said Cap Regulations (the "Unconverted Preferred
Stock") and within five (5) business days of the applicable Notice of Conversion
redeem the Unconverted Preferred Stock for an amount in cash (the "Redemption
Amount") equal to the "Economic Benefit" of such Unconverted Preferred Stock.
"Economic Benefit" for purposes of this Section 4.k. shall mean the dollar value
derived if such Unconverted Preferred Stock were converted into Common Stock as
set forth in the Notice of Conversion and the Common Stock was sold on the date
of the Notice of Conversion at the closing bid price of the Common Stock on the
date of the Notice of Conversion.  The Certificate of Designation for the
Preferred Stock shall contain provisions substantially consistent with the above
terms, with such additional provisions as may be

                                       11
<PAGE>

consented to by the Buyer. The provisions of this section are not intended to
limit the scope of the provisions otherwise included in the Certificate of
Designation.

          5.   TRANSFER AGENT INSTRUCTIONS.

          a.   Promptly following the delivery by the Buyer of the aggregate
purchase price for the Preferred Stock in accordance with Section 1(c) hereof,
the Company will irrevocably instruct its transfer agent to issue Common Stock
from time to time upon conversion of the Preferred Stock in such amounts as
specified from time to time by the Company to the transfer agent, bearing the
restrictive legend specified in Section 4(b) of this Agreement prior to
registration of the Shares under the 1933 Act, registered in the name of the
Buyer or its nominee and in such denominations to be specified by the Buyer in
connection with each conversion of the Preferred Stock.  The Company warrants
that no instruction other than such instructions referred to in this Section 5
and stop transfer instructions to give effect to Section 4(a) hereof prior to
registration and sale of the Shares under the 1933 Act will be given by the
Company to the transfer agent and that the Shares shall otherwise be freely
transferable on the books and records of the Company as and to the extent
provided in this Agreement, the Registration Rights Agreement, and applicable
law.  Nothing in this Section shall affect in any way the Buyer's obligations
and agreement to comply with all applicable securities laws upon resale of the
Securities.  If the Buyer provides the Company with an opinion of counsel
reasonably satisfactory to the Company that registration of a resale by the
Buyer of any of the Securities in accordance with clause (1)(B) of Section 4(a)
of this Agreement is not required under the 1933 Act, the Company shall (except
as provided in clause (2) of Section 4(a) of this Agreement) permit the transfer
of the Securities and, in the case of the Shares, promptly instruct the
Company's transfer agent to issue one or more certificates for Common Stock
without legend in such name and in such denominations as specified by the Buyer.

          b.   (i)  The Company will permit the Buyer to exercise its right to
convert the Preferred Stock by telecopying an executed and completed Notice of
Conversion (as defined in  the Certificate of Designation) to the Company  and
delivering within three (3) business days thereafter, the original Notice of
Conversion, together with the original share certificate, by express courier.

               (ii)  The term "Conversion Date" means, with respect to any
conversion elected by the holder of the Preferred Stock after the Effective
Date, the date specified in the Notice of Conversion, provided the copy of the
Notice of Conversion is telecopied to or otherwise delivered to the Company in
accordance with the provisions hereof so that is received by the Company on or
before such specified date. The Conversion Date for any mandatory conversion at
maturity shall be the Maturity Date of the Preferred Stock.

               (iii)  The Company shall, at its expense, take all actions and
use all means necessary and diligent to cause its transfer agent to transmit the
certificates representing the Shares issuable upon conversion of any Preferred
Stock (together with Preferred Stock not being so converted) to the Buyer via
express courier, by electronic transfer or otherwise, within three (3) business
days after receipt by the Company of the later of (i) receipt by the Company of
the copy of

                                       12
<PAGE>

the original Notice of Conversion and share certificate, and (ii) the Conversion
Date (the "Delivery Date").

          c.   The Company understands that a delay in the issuance of the
Shares of Common Stock beyond the Delivery Date could result in economic loss to
the Buyer.  As compensation to the Buyer for such loss, the Company agrees to
pay late payments to the Buyer in the event that due entirely to the Company's
failure to issue and deliver the Shares upon Conversion in accordance with the
following schedule (where "No. Business Days Late" is defined as the number of
business days beyond five (5) business days from Delivery Date):

</TABLE>

          c.   The Company shall pay any payments incurred under this Section in
immediately available funds upon demand. Nothing herein shall limit the Buyer's
right to pursue actual damages or to cause the Company to redeem the Preferred
Shares as provided below for the Company's actions or inactions resulting in the
transfer agent's failure to issue and deliver the Common Stock to the Buyer.
Furthermore, in addition to any other remedies which may be available to the
Buyer, in the event that the Company fails to deliver such shares of Common
Stock within five (5) business days after the Delivery Date, the Buyer will be
entitled to revoke the relevant Notice of Conversion by delivering a notice to
such effect to the Company whereupon the Company and the Buyer shall each be
restored to their respective positions immediately prior to delivery of such
Notice of Conversion. In the event the Company's actions or inactions result in
the transfer agent's failure to issue and deliver the Common Stock to the Buyer
within ten (10) days after the Delivery Date, Buyer may, at its option, require
the Company (without limiting its other remedies hereunder) to immediately
redeem all outstanding Preferred Stock in accordance with Section 4(k)(y).

          d.   If, by the relevant Delivery Date, the Company fails for any
reason to deliver the Shares to be issued upon conversion of the Preferred Stock
and after such Delivery Date, the holder of the Preferred Stock being converted
(a "Converting Holder") purchases, in an open market transaction or otherwise,
shares of Common Stock (the "Covering Shares") in order to make delivery in
satisfaction of a sale of Common Stock by the Converting Holder made after a
Conversion Date (the "Sold Shares"), which delivery such Converting Holder
anticipated to make using the Shares

                                       13
<PAGE>

to be issued upon such conversion (a "Buy-In"), the Company shall pay to the
Converting Holder, in addition to all other amounts contemplated in other
provisions of the Transaction Agreements, and not in lieu thereof, the Buy-In
Adjustment Amount (as defined below). The "Buy-In Adjustment Amount" is the
amount equal to the excess, if any, of (x) the Converting Holder's total
purchase price (including brokerage commissions, if any) for the Covering Shares
over (y) the net proceeds (after brokerage commissions, if any) received by the
Converting Holder from the sale of the Sold Shares. The Company shall pay the
Buy-In Adjustment Amount to the Buyer in immediately available funds immediately
upon demand by the Converting Holder. By way of illustration and not in
limitation of the foregoing, if the Converting Holder purchases shares of Common
Stock having a total purchase price (including brokerage commissions) of $11,000
to cover a Buy-In with respect to shares of Common Stock it sold for net
proceeds of $10,000, the Buy-In Adjustment Amount which Company will be required
to pay to the Converting Holder will be $1,000. The remedies set forth in
paragraphs 5(c) and (d) shall be cumulative.

          e.   In lieu of delivering physical certificates representing the
unlegended securities issuable upon conversion, provided the Company's transfer
agent is participating in the Depository Trust Company ("DTC") Fast Automated
Securities Transfer program, upon request of the Buyer and its compliance with
the provisions contained in this paragraph, so long as the certificates therefor
do not bear a legend and the Buyer thereof is not obligated to return such
certificate for the placement of a legend thereon, the Company shall use its
best efforts to cause its transfer agent to electronically transmit the Common
Stock issuable upon conversion to the Buyer by crediting the account of Buyer's
Prime Broker with DTC through its Deposit Withdrawal Agent Commission system.

          f.   The original certificate representing the Preferred Stock shall
be delivered by the Buyer to the Company simultaneous with the final Notice of
Conversion.

          6.   DELIVERY INSTRUCTIONS.

          The Preferred Stock shall be delivered by the Company to the Escrow
Agent pursuant to Section 1(b) hereof, on a delivery against payment basis, no
later than on the Closing Date.

          7.   CLOSING DATE.

          (i) The  closing of the issuance and sale of the Preferred Stock shall
occur  on the date  (the "Closing Date") which is the first NYSE trading day
after the fulfillment or waiver of all closing conditions pursuant to Sections 8
and 9 hereof or such other date and time as is mutually agreed upon by the
Company and the Buyer.

          (ii) The closing of the purchase and issuance of Preferred Stock shall
occur on the Closing Date, at the offices of the Escrow Agent and shall take
place no later than 12:00 Noon, PST, on such day or such other time as is
mutually agreed upon by the Company and the Buyer.

                                       14
<PAGE>

          (iii)  Notwithstanding anything to the contrary contained herein, the
Escrow Agent will be authorized to release the Escrow Property (as defined in
the Escrow Agreement) only upon satisfaction of the conditions set forth in
Sections 8 and 9 hereof.

          8.   CONDITIONS TO THE COMPANY'S OBLIGATION TO SELL.

          The Buyer understands that the Company's obligation to sell the
Preferred Stock on the Closing Date and to the Buyer pursuant to this Agreement
is conditioned upon:

          a.   The receipt and acceptance by the Buyer of this Agreement as
evidenced by execution of this Agreement by the Buyer for Two Million Six

Stock (or such lesser amount as the Company, in its sole discretion, shall
determine on the Closing Date);

          b.   Delivery by the Buyer to the Escrow Agent of good funds as
payment in full of an amount equal to the Purchase Price for the Preferred Stock
in accordance with Section 1(c) hereof;

          c.   The accuracy on the Closing Date of the representations and
warranties of the Buyer contained in this Agreement as if made on the Closing

Closing Date;

          d.   There shall not be in effect any law, rule or regulation
prohibiting or restricting the transactions contemplated hereby, or requiring
any consent or approval which shall not have been obtained.

          9.   CONDITIONS TO THE BUYER'S OBLIGATION TO PURCHASE.

          The Company understands that the Buyer's obligation to purchase the
Preferred Stock on the Closing Date is conditioned upon:

          a.   Acceptance by the Company of this Agreement for the sale of

          b.   Delivery by the Company to the Escrow Agent of the appropriate

          d.   On the Closing Date, Buyer having received (i) an opinion of
counsel for the Company, dated the Closing Date, in form, scope and substance
reasonably satisfactory to the Buyer, to the effect set forth in Annex III

          e.   No statute, rule, regulation, executive order, decree, ruling or
injunction shall be enacted, entered, promulgated or endorsed by any court or
governmental authority of competent jurisdiction which prohibits or adversely
effects any of the transactions contemplated by this Agreement or the
Transaction Documents, and no proceeding or investigation shall have been
commenced or threatened which may have the effect of prohibiting or adversely
effecting any of the transactions contemplated by this Agreement or the
Transaction Documents.

          f.   From and after the date hereof to and including the Closing Date,

any outbreak or escalation of hostilities involving the United States or any
material adverse change in any financial market that in either case in the
reasonable judgment of the Buyer makes it impracticable or inadvisable to
purchase the Preferred Stock.
