                        PURCHASE AND SALE OF COMMON STOCK

        SECTION 2.1 Investments.

            (a) Puts. Upon the terms and conditions set forth herein (including,
without limitation, the provisions of Article VII hereof), on any Put Date the
Company may make a Put by the delivery of a Put Notice. The number of Put Shares
that the Investor shall be obligated to purchase pursuant to such Put shall be
determined by dividing the Investment Amount specified in the Put Notice by the
Purchase Price for such Valuation Period. In connection with each Valuation
Period, the Company may set the Threshold Price, if any, in the Put Notice. If
the Market Price is less than the Threshold Price, the Company shall not sell
and the Purchaser shall not be obligated to purchase the Shares otherwise to be
purchased for such Put, except that, the Investor, in its sole discretion, may
purchase such shares at the Threshold Price.

            (b) Maximum Aggregate Amount of Puts. Anything in this Agreement to
the contrary notwithstanding, (i) at no time will the Company request a Put
which would result in the issuance of an aggregate number of shares of Common
Stock pursuant to this Agreement which exceeds 19.9% of the number of shares of
Common Stock issued and outstanding on any Closing Date without obtaining
stockholder approval of such excess issuance, and (ii) the Company may not make
a Put to the extent that, after such purchase by the Investor, the sum


                                       5
   6



of the number of shares of Common Stock and Warrants beneficially owned by the
Investor and its affiliates would result in beneficial ownership by the Investor
and its affiliates of more than 9.9% of the then outstanding shares of Common
Stock. For purposes of the immediately preceding sentence, beneficial ownership
shall be determined in accordance with Section 13(d) of the Securities and
Exchange Act of 1934, as amended.

        SECTION 2.2 Mechanics.

            (a) Put Notice. At any time during the Commitment Period, the
Company may deliver a Put Notice to the Investor, subject to the conditions set
forth in Section 7.2; provided, however, that the Investment Amount for each Put
as designated by the Company in the applicable Put Notice shall be neither less
than $100,000 nor more than the Maximum Put Amount.

            (b) Date of Delivery of Put Notice. A Put Notice shall be deemed
delivered on (i) the Trading Day it is received by facsimile or otherwise by the
Investor if such notice is received prior to 12:00 noon Eastern Time, or (ii)
the immediately succeeding Trading Day if it is received by facsimile or
otherwise after 12:00 noon Eastern Time on a Trading Day or at any time on a day
which is not a Trading Day. No Put Notice may be deemed delivered on a day that
is not a Trading Day.

        SECTION 2.3 Closings. On or before each Closing Date for a Put the
Investor shall deliver the Investment Amount specified in the Put Notice by wire
transfer of immediately available funds to the Escrow Agent, less, as to the
first six Closings only, a commitment fee equal to twenty-three thousand three
hundred thirty-three dollars ($23,333). In addition, on or prior to the Closing
Date, each of the Company and the Investor shall deliver to the Escrow Agent all
documents, instruments and writings required to be delivered or reasonably
requested by either of them pursuant to this Agreement in order to implement and
effect the transactions contemplated herein. Upon receipt of notice from the
Escrow Agent that the Escrow Agent has possession of the Investment Amount, the
Company shall, if possible, deliver the Put Shares to the Investor's account
through the Depository Trust Company DWAC system, per written account
instructions delivered by the Investor to the Company, and if the Company is not
eligible to participate in the DWAC system, to deliver to the Escrow Agent one
or more certificates, as requested by the Investor, representing the Put Shares
to be purchased by the Investor pursuant to Section 2.1 herein, registered in
the name of the Investor or, at the Investor's option, registered in the name of
such account or accounts as may be designated by the Investor. Payment of funds
to the Company and delivery of the certificates to the Investor (unless
delivered by DWAC) shall occur out of escrow in accordance with the Escrow
Agreement, provided, however, that to the extent the Company has not paid the
fees, expenses, and disbursements of the Investor's counsel in accordance with
Section 13.7, the amount of such fees, expenses, and disbursements shall be paid
in immediately available funds, at the direction of the Investor, to Investor's
counsel with no reduction in the number of Put Shares issuable to the Investor
on such Closing Date.

        SECTION 2.4 Termination of Investment Obligation.

            (a) The obligation of the Investor to purchase shares of Common
Stock and the Commitment Period shall terminate permanently (including with
respect to a Closing Date that has not yet occurred) in the event that (i) there
shall occur any stop order or suspension of the effectiveness of the
Registration Statement for an aggregate of thirty (30) Trading Days during the
Commitment Period, for any reason other than deferrals or suspensions in
accordance with the Registration Rights Agreement as a result of corporate
developments subsequent to the Effective Date that would require such
Registration Statement to be amended to reflect such event in order to maintain
its compliance with the disclosure requirements of the Securities Act or (ii)
the Company shall at any time fail to comply with the requirements of Section
6.2, 6.3 or 6.5.

            (b) If the Investor fails to honor any Put Notice within two (2)
Trading Days of the Closing Date scheduled for such Put, or otherwise becomes in
breach of any material representation, warranty, covenant or other obligation
under this Agreement including, without limitation, all exhibits attached
hereto, and the Company notifies Investor of such termination, (i) the
obligation of the Company to sell Put Shares to the Investor and, at the
election of the Company, the Commitment Period shall terminate, and


                                       6
   7


(ii) except as to any of the Warrants already exercised by the Investor, the
Investor shall return to the Company for cancellation a pro-rata portion of the
Warrants, based upon one-fifth of the warrants vesting on each of the first five
times the Company exercises a Put. Upon such termination the Company shall
maintain the Registration Statement in effect for such reasonable period, not to
exceed forty-five (45) days, as the Investor may request in order to dispose of
any remaining Put Shares. Such termination and cancellation of the Warrants
shall be the Company's sole remedy for the Investor's failure to honor a Put.

            Section 2.5 Additional Shares. In the event that (a) within five (5)
Trading Days of any Closing Date, the Company gives notice to the Investor of an
impending "blackout period" in accordance with Section 3(f) of the Registration
Rights Agreement and (b) the closing bid price on the Trading Day immediately
preceding such "blackout period" (the "Old Closing Price") is greater than the
closing bid price on the first Trading Day following such "blackout period" (the
"New Closing Price") the Company shall issue to the Investor a number of
additional shares (the "Blackout Shares") equal to the difference between (y)
the product of the number of Registrable Securities purchased by the Investor on
such most recent Closing Date and still held by the Investor during such
"blackout period" that are not otherwise freely tradable during such "blackout
period" and the Old Closing Price, divided by the New Closing Price and (z) the
number of Registrable Securities purchased by the Investor on such most recent
Closing Date and still held by the Investor during such "blackout period" that
are not otherwise freely tradable during such "blackout period". If any such
issuance would result in the issuance of a number of shares which exceeds the
number set forth in Section 2.1(b), then in lieu of such issuance and to the
extent permitted under applicable law, the Company shall pay Investor the
closing ask price of the Blackout Shares on the first Trading Day following the
end of the blackout period in cash within five Trading Days.

        SECTION 2.5 Liquidated Damages. The parties hereto acknowledge and agree
that the obligation to issue Registrable Securities under Section 2.4 above
shall constitute liquidated damages and not penalties. The parties further
acknowledge that (a) the amount of loss or damages likely to be incurred is
incapable or is difficult to precisely estimate, (b) the amounts specified in
such Sections bear a reasonable proportion and are not plainly or grossly
disproportionate to the probable loss likely to be incurred by the Investor in
connection with the failure by the Company to timely cause the registration of
the Registrable Securities or in connection with a "blackout period" under the
Registration Rights Agreement, and (c) the parties are sophisticated business
parties and have been represented by legal and financial counsel and negotiated
this Agreement at arm's length.

                                   ARTICLE III

                   REPRESENTATIONS AND WARRANTIES OF INVESTOR

                                   ARTICLE IV

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

The Company represents and warrants to the Investor that, except as set forth on
the Disclosure Schedule prepared by the Company and attached hereto:

        SECTION 4.1 Organization of the Company. The Company is a corporation
duly incorporated and existing in good standing under the laws of the State of
California and has all requisite corporate authority to own its properties and
to carry on its business as now being conducted. The Company does not have any
subsidiaries and does not own more that


                                       8
   9


fifty percent (50%) of or control any other business entity except as set forth
in the SEC Documents. The Company is duly qualified and is in good standing as a
foreign corporation to do business in every jurisdiction in which the nature of
the business conducted or property owned by it makes such qualification
necessary, other than those in which the failure so to qualify would not have a
Material Adverse Effect.

        SECTION 4.2 Authority. (i) The Company has the requisite corporate power
and corporate authority to enter into and perform its obligations under this
Agreement, the Registration Rights Agreement, the Escrow Agreement, and the
Warrants and to issue the Put Shares, the Warrants and the Warrant Shares
pursuant to their respective terms, (ii) the execution, issuance and delivery of
this Agreement, the Registration Rights Agreement, the Escrow Agreement and the
Warrants by the Company and the consummation by it of the transactions
contemplated hereby have been duly authorized by all necessary corporate action
and no further consent or authorization of the Company or its Board of Directors
or stockholders is required, and (iii) this Agreement, the Registration Rights
Agreement, the Escrow Agreement and the Warrants have been duly executed and
delivered by the Company and at the initial Closing shall constitute valid and
binding obligations of the Company enforceable against the Company in accordance
with their terms, except as such enforceability may be limited by applicable
bankruptcy, insolvency, or similar laws relating to, or affecting generally the
enforcement of, creditors' rights and remedies or by other equitable principles
of general application. The Company has duly and validly authorized and reserved
for issuance shares of Common Stock sufficient in number for the issuance of the
Put Shares and for the exercise of the Warrants.

        SECTION 4.3 Capitalization. The authorized capital stock of the Company
consists of 20,000,000 shares of Common Stock, no par value per share, of which
7,608,708 shares are issued and outstanding and 4,250,000 shares of preferred
stock of which none are issued and outstanding. Except for (i) outstanding
options and warrants as set forth in the SEC Documents and (ii) as set forth in
the Disclosure Schedule, there are no outstanding Capital Share Equivalents nor
any agreements or understandings pursuant to which any Capital Shares
Equivalents may become outstanding. The Company is not a party to any agreement
granting registration or anti-dilution rights to any person with respect to any
of its equity or debt securities. All of the outstanding shares of Common Stock
of the Company have been duly and validly authorized and issued and are fully
paid and non-assessable.

        SECTION 4.4 Common Stock. The Company has registered its Common Stock
pursuant to Section 12(b) or (g) of the Exchange Act and is in full compliance
with all reporting requirements of the Exchange Act, and the Company is in
compliance with all requirements for the continued listing or quotation of its
Common Stock, and such Common Stock is currently listed or quoted on, the
Principal Market. As of the date hereof, the Principal Market is the NASDAQ
SmallCap Market and, except as provided in the Disclosure Schedule, the Company
has not received any notice regarding, and to its knowledge there is no threat,
of the termination or discontinuance of the eligibility of the Common Stock for
such listing.

        SECTION 4.5 SEC Documents. The Company has made available to the
Investor true and complete copies of the SEC Documents. The Company has not
provided to the Investor any information that, according to applicable law, rule
or regulation, should have been disclosed publicly prior to the date hereof by
the Company, but which has not been so disclosed. As of their respective dates,
the SEC Documents complied in all material respects with the requirements of the
Exchange Act, and rules and regulations of the SEC promulgated thereunder and
the SEC Documents did not contain any untrue statement of a material fact or
omit to state a material fact required to be stated therein or necessary in
order to make the statements therein, in light of the circumstances under which
they were made, not misleading. The financial statements of the Company included
in the SEC Documents complied in all material respects with applicable
accounting requirements and the published rules and regulations of the SEC or
other applicable rules and regulations with respect thereto at the time of such
inclusion. Such financial statements have been prepared in accordance with
generally accepted accounting principles applied on a consistent basis during
the periods involved (except (i) as may be otherwise indicated in such financial
statements or the notes thereto or (ii) in the case of unaudited interim
statements, to the extent they exclude footnotes or may be condensed or summary
statements) and fairly present in all material respects the financial position
of the Company as of the dates thereof and


                                       9
   10


the results of operations and cash flows for the periods then ended (subject, in
the case of unaudited interim statements, to normal year-end audit adjustments).
Neither the Company nor any of its subsidiaries has any material indebtedness,
obligations or liabilities of any kind (whether accrued, absolute, contingent or
otherwise, and whether due or to become due) that would have been required to be
reflected in, reserved against or otherwise described in the financial
statements or in the notes thereto in accordance with GAAP, which was not fully
reflected in, reserved against or otherwise described in the financial
statements or the notes thereto included in the SEC Documents or was not
incurred in the ordinary course of business consistent with the Company's past
practices since the last date of such financial statements.

        SECTION 4.6 Valid Issuances. When issued and paid for in accordance with
the terms hereof or of the Warrants, the Put Shares and the Warrant Shares will
be duly and validly issued, fully paid, and non-assessable. Neither the sales of
the Put Shares, the Warrants or the Warrant Shares pursuant to, nor the
Company's performance of its obligations under, this Agreement, the Registration
Rights Agreement, the Escrow Agreement or the Warrants will (i) result in the
creation or imposition by the Company of any liens, charges, claims or other
encumbrances upon the Put Shares, the Warrants or the Warrant Shares or, except
as contemplated herein, any of the assets of the Company, or (ii) entitle the
holders of Outstanding Capital Shares to preemptive or other rights to subscribe
for or acquire the Capital Shares or other securities of the Company. The Put
Shares, the Warrants and the Warrant Shares shall not subject the Investor to
personal liability to the Company or its creditors by reason of the possession
thereof.

        SECTION 4.7 No Conflicts. Except as set forth on the Disclosure
Schedule, the execution, delivery and performance of this Agreement by the
Company and the consummation by the Company of the transactions contemplated
hereby, including without limitation the issuance of the Put Shares, the
Warrants and the Warrant Shares, do not and will not (i) result in a violation
of the Company's Articles of Incorporation or By-Laws or (ii) conflict with, or
constitute a material default (or an event that with notice or lapse of time or
both would become a default) under, or give to others any rights of termination,
amendment, acceleration or cancellation of, any material agreement, indenture or
instrument, or any "lock-up" or similar provision of any underwriting or similar
agreement to which the Company is a party, or (iii) result in a violation of any
federal, state or local law, rule, regulation, order, judgment or decree
(including federal and state securities laws and regulations) applicable to the
Company or by which any material property or asset of the Company is bound or
affected, nor is the Company otherwise in violation of, conflict with or default
under any of the foregoing (except in each case for such conflicts, defaults,
terminations, amendments, accelerations, cancellations and violations as would
not have, individually or in the aggregate, a Material Adverse Effect). The
business of the Company is not being conducted in violation of any law,
ordinance or regulation of any governmental entity, except for possible
violations that either singly or in the aggregate would not have a Material
Adverse Effect. The Company is not required under any Federal, state or local
law, rule or regulation to obtain any consent, authorization or order of, or
make any filing or registration with, any court or governmental agency in order
for it to execute, deliver or perform any of its obligations under this
Agreement or issue and sell the Put Shares or the Warrants in accordance with
the terms hereof (other than any SEC, Principal Market or state securities
filings that may be required to be made by the Company subsequent to the initial
Closing, any registration statement that may be filed pursuant hereto, and any
shareholder approval required by the rules applicable to companies whose common
stock trades on the Principal Market); provided that, for purposes of the
representation made in this sentence, the Company is assuming and relying upon
the accuracy of the relevant representations and agreements of the Investor
herein.

        SECTION 4.8 No Material Adverse Change. Since March 31, 2000 no Material
Adverse Effect has occurred or exists with respect to the Company, except as
disclosed in the SEC Documents.

        SECTION 4.9 No Undisclosed Events or Circumstances. Since March 31,
2000, no event or circumstance has occurred or exists with respect to the
Company or its businesses, properties, prospects, operations or financial
condition, that, under applicable law, rule or regulation, requires public
disclosure or announcement prior to the


                                       10
   11


date hereof by the Company but which has not been so publicly announced or
disclosed in the SEC Documents.

        SECTION 4.10 Litigation and Other Proceedings. Except as disclosed in
the SEC Documents, there are no lawsuits or proceedings pending or, to the
knowledge of the Company, threatened, against the Company or any subsidiary, nor
has the Company received any written or oral notice of any such action, suit,
proceeding or investigation, which could reasonably be expected to have a
Material Adverse Effect. Except as set forth in the SEC Documents, no judgment,
order, writ, injunction or decree or award has been issued by or, to the
knowledge of the Company, requested of any court, arbitrator or governmental
agency which could result in a Material Adverse Effect.

        SECTION 4.11 No Misleading or Untrue Communication. The Company and, to
the knowledge of the Company, any person representing the Company, or any other
person selling or offering to sell the Put Shares or the Warrants in connection
with the transaction contemplated by this Agreement, have not made, at any time,
any oral communication in connection with the offer or sale of the same which
contained any untrue statement of a material fact or omitted to state any
material fact necessary in order to make the statements, in the light of the
circumstances under which they were made, not misleading.

        SECTION 4.12 Material Non-Public Information. The Company has not
disclosed to the Investor any material non-public information that (i) if
disclosed publicly, would reasonably be expected to have a material effect on
the price of the Common Stock or (ii) according to applicable law, rule or
regulation, should have been disclosed publicly by the Company prior to the date
hereof but which has not been so disclosed.

        SECTION 4.13 Insurance. The Company and each subsidiary maintains
property and casualty, general liability, workers' compensation, environmental
hazard, personal injury and other similar types of insurance with financially
sound and reputable insurers that is adequate, consistent with industry
standards and the Company's historical claims experience. The Company has not
received notice from, and has no knowledge of any threat by, any insurer (that
has issued any insurance policy to the Company) that such insurer intends to
deny coverage under or cancel, discontinue or not renew any insurance policy
presently in force.

        SECTION 4.14 Tax Matters.

            The Company and each subsidiary has filed all Tax Returns which it
is required to file under applicable laws; all such Tax Returns are true and
accurate and has been prepared in compliance with all applicable laws; the
Company has paid all Taxes due and owing by it or any subsidiary (whether or not
such Taxes are required to be shown on a Tax Return) and have withheld and paid
over to the appropriate taxing authorities all Taxes which it is required to
withhold from amounts paid or owing to any employee, stockholder, creditor or
other third parties; and since December 31, 1998, the charges, accruals and
reserves for Taxes with respect to the Company (including any provisions for
deferred income taxes) reflected on the books of the Company are adequate to
cover any Tax liabilities of the Company if its current tax year were treated as
ending on the date hereof.

            No claim has been made by a taxing authority in a jurisdiction where
the Company does not file tax returns that the Company or any subsidiary is or
may be subject to taxation by that jurisdiction. There are no foreign, federal,
state or local tax audits or administrative or judicial proceedings pending or
being conducted with respect to the Company or any subsidiary; no information
related to Tax matters has been requested by any foreign, federal, state or
local taxing authority; and, except as disclosed above, no written notice
indicating an intent to open an audit or other review has been received by the
Company or any subsidiary from any foreign, federal, state or local taxing
authority. There are no material unresolved questions or claims concerning the

predecessor provision thereof or any similar provision of state, local or
foreign law; and (B) has not agreed to or is required to make any adjustments
pursuant to Section 481 (a) of the Internal Revenue Code or any similar
provision of state, local or foreign law by reason of a change in accounting

   12


method initiated by the Company or any of its subsidiaries or has any knowledge
that the IRS has proposed any such adjustment or change in accounting method, or
has any application pending with any taxing authority requesting permission for
any changes in accounting methods that relate to the business or operations of
the Company. The Company has not been a United States real property holding
corporation within the meaning of Section 897(c)(2) of the Internal Revenue Code
during the applicable period specified in Section 897(c)(1)(A)(ii) of the
Internal Revenue Code.

            The Company has not made an election under Section 341(f) of the
Internal Revenue Code. The Company is not liable for the Taxes of another person
that is not a subsidiary of the Company under (A) Treas. Reg. Section 1.1502-6
(or comparable provisions of state, local or foreign law), (B) as a transferee
or successor, (C) by contract or indemnity or (D) otherwise. The Company is not

owns any real property. Each of the Company and its subsidiaries has good and
marketable title to all personal property owned by it, free and clear of all
liens, encumbrances and defects except such as do not materially affect the
value of such property and do not materially interfere with the use made and
proposed to be made of such property by the Company; and to the Company's
knowledge any real property and buildings held under lease by the Company as
tenant are held by it under valid, subsisting and enforceable leases with such
exceptions as are not material and do not interfere with the use made and
intended to be made of such property and buildings by the Company.

        SECTION 4.16 Licensing and Permits. The Company holds all necessary and

its business as now being conducted. To the Company's knowledge, except as
disclosed in the SEC Documents neither the Company nor any of its subsidiaries
is infringing upon or in conflict with any material right of any other person
with respect to any Intangibles. Except as disclosed in the SEC Documents, no
adverse claims have been asserted by any person to the ownership or use of any
Intangibles and the Company has no knowledge of any basis for such claim.

Company further agrees, if the Company applies to have the Common Stock traded
on any other Principal Market, it will include in such application the Put
Shares and the Warrant Shares and will take such other action as is necessary or
desirable in the opinion of the investor to cause the Common Stock to be listed
on such other Principal Market as promptly as possible. The Company will take
all


                                       13
   14


action to continue the listing and trading of its Common Stock on the Principal

Company's reporting, filing and other obligations under the bylaws or rules of
the Principal Market and shall provide Investor with copies of any
correspondence to or from such Principal Market which questions or threatens
delisting of the Common Stock, within one Trading Day of the Company's receipt

        SECTION 6.7 Notice of Certain Events Affecting Registration; Suspension
of Right to Make a Put. The Company will immediately notify the Investor upon
the occurrence of any of the following events in respect of a registration
statement or related prospectus in respect of an offering of Registrable
Securities; (i) receipt of any request for additional information from the SEC
or any other federal or state governmental authority during the period of
effectiveness of the Registration Statement the response to which would require
any amendments or supplements to the registration statement or related
prospectus; (ii) the issuance by the SEC or any other federal or state
governmental authority of any stop order suspending the effectiveness of the
Registration Statement or the initiation of any proceedings for that purpose;
(iii) receipt of any notification with respect to the suspension of the
qualification or exemption from qualification of any of the Registrable

proceeding for such purpose; (iv) the happening of any event that to the
Company's knowledge makes any statement made in the Registration Statement or

statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein not misleading, and
that in the case of the related prospectus, it will not contain 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 therein, in the light of the
circumstances under which they were made, not misleading; and (v) the Company's
reasonable determination that a post-effective amendment to the Registration
Statement would be appropriate; and the Company will promptly make available to
the Investor any such supplement or amendment to the related prospectus. The
Company shall not deliver to the Investor any Put Notice during the continuation
of any of the foregoing events.

        SECTION 6.8 Expectations Regarding Put Notices. Within ten (10) days

writing, as to its reasonable expectations as to the dollar amount it intends to
raise during such calendar quarter, if any, through the issuance of Put Notices.
Such notification shall constitute only the Company's good faith estimate and
shall in no way obligate the Company to raise such amount, or any amount, or
otherwise limit its ability to deliver Put Notices. The failure by the Company
to comply with this provision can be cured by the Company's notifying the


                                       14
   15

Investor, in writing, at any time as to its reasonable expectations with respect

acquiring entity (if not the Company) assumes by written instrument or by
operation of law the obligation to deliver to the Investor such shares of stock
and/or securities as the Investor is entitled to receive pursuant to this
Agreement.

        SECTION 6.10 Limitation on Future Financing. The Company agrees that it
will not enter into any sale of its securities for cash at a discount to its
then-current closing bid price during the Commitment Period except for any sales
(i) pursuant to any presently existing stock incentive plan as amended from time

approved by the Company's stockholders, (ii) pursuant to any compensatory plan
for a full-time employee, director or key consultant, (iii) pursuant to any
underwritten public offering with an established investment bank, (iv) in
connection with a strategic partnership or other business transaction, the
principal purpose of which is not simply to raise money, (v) pursuant to any
option, warrant or agreement outstanding on the date of this Agreement, or (vi)
with the prior approval of the Investor, which will not be unreasonably
withheld. Further, the Investor shall have a right of first refusal, to elect to
participate, in such subsequent transaction in the case of (iii) and (vi) above.
Such right of first refusal must be exercised in writing within seven (7)
Trading Days of the Investor's receipt of notice of the proposed terms of such
financing.

        SECTION 7.1 Conditions Precedent to the Obligation of the Company to
Issue and Sell Common Stock. The obligation hereunder of the Company to issue
and sell the Put Shares to the Investor incident to each Closing is subject to
the satisfaction, at or before each such Closing, of each of the conditions set
forth below.

                (a) Accuracy of the Investor's Representation and Warranties.
The representations and warranties of the Investor shall be true and correct in
all material respects as of the date of this Agreement and as of the date of
each such Closing as though made at each such time.

                (b) Performance by the Investor. The Investor shall have
performed, satisfied and complied in all material respects with all covenants,
agreements and conditions required by this Agreement to be performed, satisfied
or complied with by the Investor at or prior to such Closing, and Investor shall
provide a certificate to the Company, substantially in the form of that
delivered by the Investor.

        SECTION 7.2 Conditions Precedent to the Right of the Company to Deliver

right of the Company to deliver a Put Notice and the obligation of Investor
hereunder to acquire and pay for the Put Shares incident to a Closing is subject
to the satisfaction, on both (i) the date of delivery of such Put Notice and
(ii) the applicable Closing Date (each a "Condition Satisfaction Date"), of each
of the following conditions:

                (a) Closing Certificate. All representations and warranties of
the Company contained herein shall remain true and correct in all material
respects as of the Closing Date as though made as of such date and the Company
shall have delivered into escrow an Officer's Certificate signed by its Chief
Executive Officer certifying that to the best of such officer's knowledge all of

                                       15
   16


            (b) Blue Sky. The Company shall have obtained all permits and
qualifications required by any state for the offer and sale of the Common Stock
to the Investor and by the Investor as set forth in the Registration Rights
Agreement or shall have the availability of exemptions therefrom;

            (c) Delivery of Put Shares. Delivery into escrow or to DTC of the
Put Shares;

            (d) Opinion of Counsel. Receipt by the Investor of an opinion of
counsel to the Company, in the form of Exhibit D hereto; and

            (e) Transfer Agent. Delivery to the Company's transfer agent of
instructions to such transfer agent in form and substance reasonably
satisfactory to the Investor.

            (f) Registration of the Common Stock with the SEC. The Registration
Statement shall have previously become effective and shall remain effective and
available for making resales of the Put Shares and Warrant Shares by the
Investor on each Condition Satisfaction Date and (i) neither the Company nor the
Investor shall have received notice that the SEC has issued or intends to issue
a stop order with respect to the Registration Statement or that the SEC
otherwise has suspended or withdrawn the effectiveness of the Registration
Statement, either temporarily or permanently, or intends or has threatened to do
so (unless the SEC's concerns have been addressed and the Investor is reasonably
satisfied that the SEC no longer is considering or intends to take such action),
and (ii) no other suspension of the use or withdrawal of the effectiveness of
the Registration Statement or related prospectus shall exist.

            (g) Authority. The Company will satisfy all laws and regulations
pertaining to the sale and issuance of the Put Shares.

            (h) Performance by the Company. The Company shall have performed,

and conditions required by this Agreement, the Registration Rights Agreement and
the Escrow Agreement to be performed, satisfied or complied with by the Company

            (i) No Injunction. No statute, rule, regulation, executive order,
decree, ruling or injunction shall have been enacted, entered, promulgated or
endorsed by any court or governmental authority of competent jurisdiction that
prohibits or directly and adversely affects any of the transactions contemplated
by this Agreement, and no proceeding shall have been commenced that may have the
effect of prohibiting or adversely affecting any of the transactions
contemplated by this Agreement.

            (j) Adverse Changes. Since the date of filing of the Company's most
recent SEC Document, no event that had or is reasonably likely to have a
Material Adverse Effect has occurred.

            (k) No Suspension of Trading In or Delisting of Common Stock. The
trading of the Common Stock (including, without limitation, the Put Shares) is
not suspended by the SEC or the Principal Market, and the Common Stock
(including, without limitation, the Put Shares) shall have been approved for
listing or quotation on and shall not have been delisted from the Principal
Market. The issuance of shares of Common Stock with respect to the applicable
Closing, if any, shall not violate the shareholder approval requirements of the
Principal Market. The Company shall not have received any notice threatening to
delist the Common Stock from the Principal Market.

            (l) No Knowledge. The Company has no knowledge of any event more
likely than not to have the effect of causing such Registration Statement to be
suspended or otherwise ineffective (which event is reasonably likely to occur
within the thirty (30) Trading Days following the Trading Day on which such
Notice is deemed delivered).

            (m) Trading Cushion. The Trading Cushion shall have elapsed since
the next preceding Put Date.

in this Section 7.2.

                                  ARTICLE VIII

         DUE DILIGENCE REVIEW; NON-DISCLOSURE OF NON-PUBLIC INFORMATION.

        SECTION 8.1 Due Diligence Review. The Company shall make available for
inspection and review by the Investor, advisors to and representatives of the
Investor (who may or may not be affiliated with the Investor and who are
reasonably acceptable to the Company), any underwriter participating in any
disposition of the Registrable Securities on behalf of the Investor pursuant to
the Registration Statement, any such registration statement or amendment or
supplement thereto or any blue sky, NASD or other filing, all SEC Documents and
other filings with the SEC, and all other publicly available corporate documents
and properties of the Company as may be reasonably necessary for the purpose of
such review, and cause the Company's officers, directors and employees to supply
all such publicly available information reasonably requested by the Investor or
any such representative, advisor or underwriter in connection with such
Registration Statement (including, without limitation, in response to all
questions and other inquiries reasonably made or submitted by any of them),
prior to and from time to time after the filing and effectiveness of the
Registration Statement for the sole purpose of enabling the Investor and such
representatives, advisors and underwriters and their respective accountants and
attorneys to conduct initial and ongoing due diligence with respect to the
Company and the accuracy of the Registration Statement.

        SECTION 8.2 Non-Disclosure of Non-Public Information.

            (a) The Company shall not disclose non-public information to the
Investor, advisors to or representatives of the Investor unless prior to
disclosure of such information the Company identifies such information as being
non-public information and provides the Investor, such advisors and
representatives with the opportunity to accept or refuse to accept such
non-public information for review. The Company may, as a condition to disclosing
any non-public information hereunder, require the Investor's advisors and
representatives to enter into a confidentiality agreement in form reasonably
satisfactory to the Company and the Investor.

            (b) The Company represents that it does not disseminate non-public
information to any investors who purchase stock in the Company in a public
offering, to money managers or to securities analysts, provided, however, that
notwithstanding anything herein to the contrary, the Company will, as
hereinabove provided, immediately notify the advisors and representatives of the
Investor and, if any, underwriters, of any event or the existence of any
circumstance (without any obligation to disclose the specific event or
circumstance) of which it becomes aware, constituting non-public information
(whether or not requested of the Company specifically or generally during the
course of due diligence by such persons or entities), which, if not disclosed in
the prospectus included in the Registration Statement would cause such
prospectus to include a material misstatement or to omit a material fact
required to be stated therein in order to make the statements, therein in light
of the circumstances in which they were made, not misleading. Nothing contained
in this Section 8.2 shall be construed to mean that such persons or entities
other than the Investor (without the written consent of the Investor prior to
disclosure of such information) may not obtain non-public information in the
course of conducting due diligence in accordance with the terms of this
Agreement and nothing herein shall prevent any such persons or entities from
notifying the Company of their opinion that based on such due diligence by such
persons or entities, that the Registration Statement contains an untrue
statement of a material fact or omits a material fact required to be stated in
the Registration Statement or necessary to make the statements contained
therein, in light of the circumstances in which they were made, not misleading.

                           TRANSFER AGENT INSTRUCTIONS

        SECTION 9.1 Transfer Agent Instructions. Upon each Closing, the Company
will issue to the transfer agent for its Common Stock (and to any substitute or
replacement transfer agent for its Common Stock upon the Company's appointment
of any such substitute or replacement transfer agent) instructions to deliver
the Put Shares without restrictive legends to the Escrow Agent.

        SECTION 9.2 No Legend or Stock Transfer Restrictions. No legend shall be
placed on the share certificates representing the Put Shares and no instructions
or "stop transfer orders," so called, "stock transfer restrictions," or other
restrictions have been or shall be given to the Company's transfer agent with
respect thereto.

        SECTION 9.3 Investor's Compliance. Nothing in this Article shall affect
in any way the Investor's obligations under any agreement to comply with all
applicable securities laws upon resale of the Put Shares.

                                  CHOICE OF LAW

        SECTION 10.1 Governing Law/Arbitration. This Agreement shall be governed
by and construed in accordance with the laws of the State of California
applicable to contracts made in California by persons domiciled in San Francisco
and without regard to its principles of conflicts of laws. Any dispute under
this Agreement or any Exhibit attached hereto shall be submitted to arbitration
under the American Arbitration Association (the "AAA") in San Francisco,
California, and shall be finally and conclusively determined by the decision of
a board of arbitration consisting of three (3) members (hereinafter referred to
as the "Board of Arbitration") selected as according to the rules governing the
AAA. The Board of Arbitration shall meet on consecutive business days in San
Francisco, California, and shall reach and render a decision in writing
(concurred in by a majority of the members of the Board of Arbitration) with
respect to the amount, if any, which the losing party is required to pay to the
other party in respect of a claim filed. In connection with rendering its
decisions, the Board of Arbitration shall adopt and follow the laws of the State
of California. To the extent practical, decisions of the Board of Arbitration
shall be rendered no more than thirty (30) calendar days following commencement
of proceedings with respect thereto. The Board of Arbitration shall cause its
written decision to be delivered to all parties involved in the dispute. The
Board of Arbitration shall be authorized and is directed to enter a default
judgment against any party refusing to participate in the arbitration proceeding
within thirty days of any deadline for such participation. Any decision made by
the Board of Arbitration (either prior to or after the expiration of such thirty
(30) calendar day period) shall be final, binding and conclusive on the parties
to the dispute, and entitled to be enforced to the fullest extent permitted by
law and entered in any court of competent jurisdiction. The prevailing party
shall be awarded its costs, including attorneys' fees, from the non-prevailing
party as part of the arbitration award. Any party shall have the right to seek
injunctive relief from any court of competent jurisdiction in any case where
such relief is available. The prevailing party in such injunctive action shall
be awarded its costs, including attorney's fees, from the non-prevailing party.

                                   ARTICLE XI

                                   ASSIGNMENT

        SECTION 11.1 Assignment. Neither this Agreement nor any rights of the
Investor or the Company hereunder may be assigned by either party to any other
person except by operation of law. Notwithstanding the foregoing, upon the prior
written consent of the Company, which consent shall not unreasonably be withheld
or delayed in the case of an assignment to an affiliate of the Investor, the
Investor's interest in this Agreement may be assigned at any time, in whole or
in part, to any other person or entity (including any


                                       18

affiliate of the Investor) who agrees to make the representations and warranties
contained in Article III and who agrees to be bound hereby.

        SECTION 13.1 Counterparts/ Facsimile/ Amendments. This Agreement may be
executed in multiple counterparts, each of which may be executed by less than
all of the parties and shall be deemed to be an original instrument which shall
be enforceable against the parties


                                       19
   20


actually executing such counterparts and all of which together shall constitute
one and the same instrument. Except as otherwise stated herein, in lieu of the
original documents, a facsimile transmission or copy of the original documents
shall be as effective and enforceable as the original. This Agreement may be
amended only by a writing executed by all parties.

        SECTION 13.2 Entire Agreement. This Agreement, the Exhibits hereto,
which include, but are not limited to the Escrow Agreement, the Registration
Rights Agreement and the Warrants, set forth the entire agreement and
understanding of the parties relating to the subject matter hereof and
supersedes all prior and contemporaneous agreements, negotiations and
understandings between the parties, both oral and written relating to the
subject matter hereof. The terms and conditions of all Exhibits to this
Agreement are incorporated herein by this reference and shall constitute part of
this Agreement as is fully set forth herein.

        SECTION 13.3 Survival; Severability. The representations, warranties,
covenants and agreements of the parties hereto shall survive each Closing
hereunder. In the event that any provision of this Agreement becomes or is
declared by a court of competent jurisdiction to be illegal, unenforceable or
void, this Agreement shall continue in full force and effect without said
provision; provided that such severability shall be ineffective if it materially
changes the economic benefit of this Agreement to any party.

        SECTION 13.4 Title and Subtitles. The titles and subtitles used in this
Agreement are used for convenience only and are not to be considered in
construing or interpreting this Agreement.

        SECTION 13.5 Reporting Entity for the Common Stock. The reporting entity
relied upon for the determination of the trading price or trading volume of the
Common Stock on any given Trading Day for the purposes of this Agreement shall
be Bloomberg, L.P. or any successor thereto. The written mutual consent of the
Investor and the Company shall be required to employ any other reporting entity.

        SECTION 13.6 Replacement of Certificates. Upon (i) receipt of evidence
reasonably satisfactory to the Company of the loss, theft, destruction or
mutilation of a certificate representing the Put Shares and (ii) in the case of
any such loss, theft or destruction of such certificate, upon delivery of an
indemnity agreement or security reasonably satisfactory in form and amount to
the Company (which shall not exceed that required by the Company's transfer
agent in the ordinary course) or (iii) in the case of any such mutilation, on
surrender and cancellation of such certificate, the Company at its expense will
execute and deliver, in lieu thereof, a new certificate of like tenor.

        SECTION 13.7 Fees and Expenses. Each of the Company and the Investors
agrees to pay its own expenses incident to the performance of its obligations
hereunder, except that the Company shall pay the fees, expenses and
disbursements of Investors' counsel in the amount of $15,000 plus $1,500 per
Closing of a Put.

        SECTION 13.8 Brokerage. Each of the parties hereto represents that it
has had no dealings in connection with this transaction with any finder or
broker who will demand payment of any fee or commission from the other party.
The Company on the one hand, and the Investor, on the other hand, agree to
indemnify the other against and hold the other harmless from any and all
liabilities to any person claiming brokerage commissions or finder's fees on
account of services purported to have been rendered on behalf of the
indemnifying party in connection with this Agreement or the transactions
contemplated hereby.

        SECTION 13.9 Publicity. The Company agrees that it will not issue any
press release or other public announcement of the transactions contemplated by
this Agreement without the prior consent of the Investor, which shall not be
unreasonably withheld nor delayed by more than two (2) Trading Days from its
receipt of such proposed release; provided, however, that if the Company is
advised by its outside counsel that it is required by law or the applicable
rules of any Principal Market to issue any such press release or public
announcement, then, it may do so without the prior consent of the


                                       20
   21

Investor, although it shall be required to provide prior notice (which may be by
telephone) to the Investor that it intends to issue such press release or public
announcement. No release shall name the Investor without its express consent.

        SECTION 13.10 Effectiveness of Agreement. This Agreement shall become
effective only upon satisfaction of the conditions precedent to the Initial
Closing set forth in Article I of the Escrow Agreement.

under the laws of the State of California (the "Company"), Triton West Group,
Inc., a British Virgin Islands corporation ("Investor"), and Epstein Becker &

shall have the meanings set forth in the Private Equity Line of Credit Agreement
referred to in the first recital.

                              W I T N E S S E T H:


            WHEREAS, the Investor will from time to time as requested by the

will be issued as per the terms and conditions contained herein and in the
Purchase Agreement; and

            WHEREAS, the Company and the Investor have requested that the Escrow
Agent hold in escrow and then distribute the initial documents and certain funds
which are conditions precedent to the effectiveness of the Purchase Agreement,
and have further requested that upon each exercise of a Put, the Escrow Agent
hold the relevant documents and the applicable purchase price pending receipt by
the Investor of certificates representing the securities issuable upon such Put;

            NOW, THEREFORE, in consideration of the covenants and mutual
promises contained herein and other good and valuable consideration, the receipt
and legal sufficiency of which are hereby acknowledged and intending to be
legally bound hereby, the parties agree as follows:

                   TERMS OF THE ESCROW FOR THE INITIAL CLOSING

            1.1. The parties hereby agree to establish an escrow account with

               (iv)   the sum of $15,000;

               (v)    a certificate representing five thousand (5,000) shares of

                        TERMS OF THE ESCROW FOR EACH PUT

            2.1. (a) Each time the Company shall send a Put Notice to the
Investor as provided in the Purchase Agreement, it shall send a copy, by

                (b) Each time the Investor shall purchase shares pursuant to a
Put, the Investor shall send the applicable Investment Amount of the Put Shares
to the Escrow Agent on or before the Closing Date for such Put, less, as to the
first six Closings only, a commitment fee equal to twenty-three thousand three
hundred thirty-three dollars ($23,333). The Company shall promptly, but no later
than five (5) Trading Days after receipt of notice from the Escrow Agent that it
has the funds for the Investment Amount cause its Transfer Agent to deliver the

possible, or else to deliver such certificates to the Escrow Agent. In the event
that the certificates representing the Put Shares are not in the Investor's or
the Escrow Agent's possession within five (5) Trading Days of the date of the
Escrow Agent's notice, then Investor shall have the right to demand, by notice,
the return of the Investment Amount, and the Put Notice shall be deemed
cancelled. The Escrow Agent shall within one (1) Trading Day of Closing wire the
Purchase Price per the written instructions of the Company net of One Thousand
Five Hundred Dollars ($1,500) as escrow expenses to the Escrow Agent.

                                  MISCELLANEOUS

            3.1. No waiver or any breach of any covenant or provision herein
contained shall be deemed a waiver of any preceding or succeeding breach
thereof, or of any other covenant or provision herein contained. No extension of
time for performance of any obligation or act shall be deemed an extension of
the time for performance of any other obligation or act.

All notices or other communications required or permitted hereunder shall be in
writing, and shall be sent by fax, overnight courier, registered or certified
mail, postage prepaid, return receipt requested, and shall be deemed received
upon receipt thereof, as set forth in the Purchase Agreement.

            3.2. This Escrow Agreement shall be binding upon and shall inure to
the benefit of the permitted successors and permitted assigns of the parties
hereto.

   25


            3.3. This Escrow Agreement is the final expression of, and contains
the entire agreement between, the parties with respect to the subject matter
hereof and supersedes all prior understandings with respect thereto. This Escrow
Agreement may not be modified, changed, supplemented or terminated, nor may any
obligations hereunder be waived, except by written instrument signed by the
parties to be charged or by their respective agents duly authorized in writing
or as otherwise expressly permitted herein.

            3.4. Whenever required by the context of this Escrow Agreement, the
singular shall include the plural and masculine shall include the feminine. This
Escrow Agreement shall not be construed as if it had been prepared by one of the
parties, but rather as if both parties had prepared the same. Unless otherwise
indicated, all references to Articles are to this Escrow Agreement.

            3.5. The parties hereto expressly agree that this Escrow Agreement
shall be governed by, interpreted under and construed and enforced in accordance
with the laws of the State of New York. Except as expressly set forth herein,
any action to enforce, arising out of, or relating in any way to, any provisions
of this Escrow Agreement shall brought through the American Arbitration
Association at the designated locale of New York, New York as is more fully set
forth in the Purchase Agreement.

            3.6. The Escrow Agent's duties hereunder may be altered, amended,
modified or revoked only by a writing signed by the Company, each Investor and
the Escrow Agent.

            3.7. The Escrow Agent shall be obligated only for the performance of
such duties as are specifically set forth herein and may rely and shall be
protected in relying or refraining from acting on any instrument reasonably
believed by the Escrow Agent to be genuine and to have been signed or presented
by the proper party or parties. The Escrow Agent shall not be personally liable
for any act the Escrow Agent may do or omit to do hereunder as the Escrow Agent
while acting in good faith, excepting only its own gross negligence or willful
misconduct, and any act done or omitted by the Escrow Agent pursuant to the
advice of the Escrow Agent's attorneys-at-law (other than Escrow Agent itself)
shall be conclusive evidence of such good faith.

            3.8. The Escrow Agent is hereby expressly authorized to disregard
any and all warnings given by any of the parties hereto or by any other person
or corporation, excepting only orders or process of courts of law and is hereby
expressly authorized to comply with and obey orders, judgments or decrees of any
court. In case the Escrow Agent obeys or complies with any such order, judgment
or decree, the Escrow Agent shall not be liable to any of the parties hereto or
to any other person, firm or corporation by reason of such decree being
subsequently reversed, modified, annulled, set aside, vacated or found to have
been entered without jurisdiction.

            3.9. The Escrow Agent shall not be liable in any respect on account
of the identity, authorization or rights of the parties executing or delivering
or purporting to execute or deliver the Purchase Agreement or any documents or
papers deposited or called for thereunder or hereunder.

            3.10. The Escrow Agent shall be entitled to employ such legal
counsel and other experts as the Escrow Agent may deem necessary properly to
advise the Escrow Agent in connection with the Escrow Agent's duties hereunder,
may rely upon the advice of such counsel, and may pay such counsel reasonable
compensation therefor. THE ESCROW AGENT HAS ACTED AS LEGAL COUNSEL FOR THE
INVESTOR, AND MAY CONTINUE TO ACT AS LEGAL COUNSEL FOR THE INVESTOR, FROM TIME
TO TIME, NOTWITHSTANDING ITS DUTIES AS THE ESCROW AGENT HEREUNDER. THE COMPANY
CONSENTS TO THE ESCROW AGENT IN SUCH CAPACITY AS LEGAL COUNSEL FOR THE INVESTORS
AND WAIVES ANY CLAIM THAT SUCH REPRESENTATION REPRESENTS A CONFLICT OF INTEREST
ON THE PART OF THE ESCROW AGENT. THE COMPANY UNDERSTANDS THAT THE INVESTOR AND
THE ESCROW AGENT ARE RELYING EXPLICITLY ON THE FOREGOING PROVISION IN ENTERING
INTO THIS ESCROW AGREEMENT.

            3.11. The Escrow Agent's responsibilities as escrow agent hereunder
shall terminate if the Escrow Agent shall resign by written notice to the
Company and the Investor. In the event of any such resignation, the Investors
and the Company shall each


                                       3
   26


use their reasonable best efforts as quickly as practicable to appoint a
successor Escrow Agent.

            3.12. If the Escrow Agent reasonably requires other or further
instruments in connection with this Escrow Agreement or obligations in respect
hereto, the necessary parties hereto shall join in furnishing such instruments.

            3.13. It is understood and agreed that should any dispute arise with
respect to the delivery and/or ownership or right of possession of the documents
or the escrow funds held by the Escrow Agent hereunder, the Escrow Agent is
authorized and directed in the Escrow Agent's sole discretion (1) to retain in
the Escrow Agent's possession without liability to anyone all or any part of
said documents or the escrow funds until such disputes shall have been settled
either by mutual written agreement of the parties concerned by a final order,
decree or judgment or a court of competent jurisdiction after the time for
appeal has expired and no appeal has been perfected, but the Escrow Agent shall
be under no duty whatsoever to institute or defend any such proceedings or (2)
to deliver the escrow funds and any other property and documents held by the
Escrow Agent hereunder to a state or federal court having competent subject
matter jurisdiction and located in the State and City of New York in accordance
with the applicable procedure therefor.

            3.14. The Company and the Investor agree jointly and severally to
indemnify and hold harmless the Escrow Agent and its partners, employees, agents
and representatives from any and all claims, liabilities, costs or expenses in
any way arising from or relating to the duties or performance of the Escrow
Agent hereunder or the transactions contemplated hereby or by the Purchase
Agreement other than any such claim, liability, cost or expense to the extent
the same shall have been determined by final, unappealable judgment of a court
of competent jurisdiction to have resulted from the gross negligence or willful
misconduct of the Escrow Agent.

                          REGISTRATION RIGHTS AGREEMENT

THIS REGISTRATION RIGHTS AGREEMENT, dated as of the 15th day of August, 2000,
between Triton West Group, Inc. ("Holder") and Planet Polymer Technologies, Inc.
a corporation incorporated under the laws of the State of California (the
"Company").

            WHEREAS, simultaneously with the execution and delivery of this
Agreement, pursuant to a Private Equity Line of Credit Agreement dated the date
hereof (the "Purchase Agreement") the Holder has committed to purchase up to
$7,000,000 pursuant to the Purchase Agreement of the Company's Common Stock
(terms not defined herein shall have the meanings ascribed to them in the
Purchase Agreement); and

            WHEREAS, the Company desires to grant to the Holder the registration
rights set forth herein with respect to the Put Shares and the Blackout Shares
issuable upon exercise of the Company's Put rights from time to time and the
Warrant Shares (hereinafter referred to as the "Put Shares" or "Stock" or
"Securities" of the Company).

            NOW, THEREFORE, the parties hereto mutually agree as follows:

            SECTION 1. Registrable Securities. As used herein the term
"Registrable Security" means the Securities until (i) all Put Shares and Warrant
Shares have been disposed of pursuant to the Registration Statement, (ii) all
Put Shares and Warrant Shares have been sold under circumstances under which all
of the applicable conditions of Rule 144 (or any similar provision then in
force) under the Securities Act ("Rule 144") are met, (iii) all Put Shares and
Warrant Shares have been otherwise transferred to persons who may trade such
Securities without restriction under the Securities Act, and the Company has
delivered a new certificate or other evidence of ownership for such Put Shares
and Warrant Shares not bearing a restrictive legend or (iv) such time as, in the
opinion of counsel to the Company, all Put Shares and Warrant Shares may be sold
without any time, volume or manner limitations pursuant to Rule 144(k) (or any
similar provision then in effect) under the Securities Act. The term
"Registrable Securities" means any and/or all of the securities falling within
the foregoing definition of a "Registrable Security." In the event of any
merger, reorganization, consolidation, recapitalization or other change in
corporate structure affecting the Common Stock, such adjustment shall be deemed
to be made in the definition of "Registrable Security" as is appropriate in
order to prevent any dilution or enlargement of the rights granted pursuant to
this Agreement.

            SECTION 2. Restrictions on Transfer. The Holder acknowledges and
understands that in the absence of an effective Registration Statement
authorizing the resale of the Securities as provided herein, the Securities are
"restricted securities" as defined in Rule 144 promulgated under the Act. The
Holder understands that no disposition or transfer of the Securities may be made
by Holder in the absence of (i) an opinion of counsel to the Holder, in form and
substance reasonably satisfactory to the Company, that such transfer may be made
without registration under the Securities Act or (ii) such registration.

            With a view to making available to the Holder the benefits of Rule
144 under the Securities Act or any other similar rule or regulation of the
Commission that may at any time permit the Holder to sell securities of the
Company to the public without registration ("Rule 144"), the Company agrees to:

            (a) comply with the provisions of paragraph (c)(1) of Rule 144; and

            (b) file with the Commission in a timely manner all reports and
other documents required to be filed by the Company pursuant to Section 13 or
15(d) under the Exchange Act; and, if at any time it is not required to file
such reports but in the past had been required to or did file such reports, it
will, upon the request of any Holder, make available other information as
required by, and so long as necessary to permit sales of, its Registrable
Securities pursuant to Rule 144.


                                       1
   30

            SECTION 3. Registration Rights With Respect to the Securities.

            (a) The Company agrees that it will prepare and file with the
Securities and Exchange Commission ("Commission"), within forty-five (45) days
after the date hereof, one or more registration statements (on Form S-1, S-3, or
other appropriate form of registration statement) under the Securities Act (the
"Registration Statement"), at the sole expense of the Company (except as
provided in Section 3(c) hereof), so as to permit a public offering and resale
of the Securities under the Act by Holder.

                The Company shall use its best efforts to cause the Registration
Statement to become effective within ninety (90) days from the date hereof, or,
if earlier, within five (5) days of SEC clearance to request acceleration of
effectiveness. The number of shares designated in the Registration Statement to
be registered shall be such number of shares as the Company reasonably expects
to issue from the date thereof pursuant to this Agreement (including the Warrant
Shares and Blackout Shares) and shall include appropriate language regarding
reliance upon Rule 416 to the extent permitted by the Commission. The Company
will notify Holder of the effectiveness of the Registration Statement within one
Trading Day of such event.

            (b) The Company will maintain the Registration Statement or
post-effective amendment filed under this Section 3 hereof effective under the
Securities Act until the earlier of (i) the date that none of the Securities are
or may become issued and outstanding, (ii) the date that all of the Securities
have been sold pursuant to the Registration Statement, (iii) the date the
holders thereof receive an opinion of counsel to the Company, which counsel
shall be reasonably acceptable to the Holder, that the Securities may be sold
under the provisions of Rule 144 without limitation as to volume, (iv) all
Securities have been otherwise transferred to persons who may trade such shares
without restriction under the Securities Act, and the Company has delivered a
new certificate or other evidence of ownership for such securities not bearing a
restrictive legend, (v) two (2) years from the date of the last Put or (vi) all
Securities may be sold without any time, volume or manner limitations pursuant
to Rule 144(k) or any similar provision then in effect under the Securities Act
in the opinion of counsel to the Company, which counsel shall be reasonably
acceptable to the Holder (the "Effectiveness Period").

            (c) All fees, disbursements and out-of-pocket expenses and costs
incurred by the Company in connection with the preparation and filing of the
Registration Statement under subparagraph 3(a) and in complying with applicable
securities and Blue Sky laws (including, without limitation, all attorneys' fees
of the Company) shall be borne by the Company. The Holder shall bear the cost of
underwriting and/or brokerage discounts, fees and commissions, if any,
applicable to the Securities being registered and the fees and expenses of its
counsel. The Holder and its counsel shall have a reasonable period, not to
exceed ten (10) Trading Days, to review the proposed Registration Statement or
any amendment thereto, prior to filing with the Commission, and the Company
shall provide each Holder with copies of any comment letters received from the
Commission with respect thereto within two (2) Trading Days of receipt thereof.
The Company shall make reasonably available for inspection by Holder, any
underwriter participating in any disposition pursuant to the Registration
Statement, and any attorney, accountant or other agent retained by such Holder
or any such underwriter all relevant financial and other records, pertinent
corporate documents and properties of the Company and its subsidiaries, and
cause the Company's officers, directors and employees to supply all information
reasonably requested by such Holder or any such underwriter, attorney,
accountant or agent in connection with the Registration Statement, in each case,
as is customary for similar due diligence examinations; provided, however, that
all records, information and documents that are designated in writing by the
Company, in good faith, as confidential, proprietary or containing any material
non-public information shall be kept confidential by such Holder and any such
underwriter, attorney, accountant or agent (pursuant to an appropriate
confidentiality agreement in the case of any such Holder or agent), unless such
disclosure is made pursuant to judicial process in a court proceeding (after
first giving the Company an opportunity promptly to seek a protective order or
otherwise limit the scope of the information sought to be disclosed) or is
required by law, or such records, information or documents become available to
the public generally or through a third party not in violation of an
accompanying obligation of confidentiality; and provided further that, if the
foregoing inspection and information gathering would otherwise disrupt the
Company's conduct of its business, such inspection and information gathering
shall, to the maximum


                                       2
   31


extent possible, be coordinated on behalf of the Holder and the other parties
entitled thereto by one firm of counsel designated by and on behalf of the
majority in interest of Holder and other parties. The Company shall qualify any
of the securities for sale in such states as such Holder reasonably designates
and shall furnish indemnification in the manner provided in Section 6 hereof.
However, the Company shall not be required to qualify in any state which will
require an escrow or other restriction relating to the Company and/or the
sellers, or which will require the Company to qualify to do business in such
state or require the Company to file therein any general consent to service of
process. The Company at its expense will supply the Holder with copies of the
Registration Statement and the prospectus included therein and other related
documents in such quantities as may be reasonably requested by the Holder.

            (d) The Company shall not be required by this Section 3 to include a
Holder's Securities in any Registration Statement which is to be filed if, in
the opinion of counsel for both the Holder and the Company (or, should they not
agree, in the opinion of another counsel experienced in securities law matters
acceptable to counsel for the Holder and the Company) the proposed offering or
other transfer as to which such registration is requested is exempt from
applicable federal and state securities laws and would result in all purchasers
or transferees obtaining securities which are not "restricted securities", as
defined in Rule 144 under the Securities Act.

            (e) No provision contained herein shall preclude the Company from
selling securities pursuant to any Registration Statement in which it is
required to include Securities pursuant to this Section 3.

            (f) If at any time or from time to time after the effective date of
the Registration Statement, the Company notifies the Holder in writing of the
existence of a Potential Material Event (as defined in Section 3(g) below), the
Holder shall not offer or sell any Securities or engage in any other transaction
involving or relating to Securities, from the time of the giving of notice with
respect to a Potential Material Event until such Holder receives written notice
from the Company that such Potential Material Event either has been disclosed to
the public or no longer constitutes a Potential Material Event; provided,
however, that if the Company so suspends the right to such holders of Securities
for more than thirty (30) days in the aggregate during any twelve month period,
during the periods the Registration Statement is required to be in effect such
excess periods shall be a Registration Default, and shall entitle the Investor
to receive Blackout Shares as provided in the Purchase Agreement. If a Potential
Material Event shall occur prior to the date the Registration Statement is
filed, then the Company's obligation to file the Registration Statement shall be
delayed without penalty for not more than thirty (30) days. The Company must
give Holder notice in writing at least two (2) Trading Days prior to the first
day of the blackout period, if lawful to do so.

            (g) "Potential Material Event" means any of the following: (a) the
possession by the Company of material information that is not ripe for
disclosure in a registration statement, as determined in good faith by the Chief
Executive Officer or the Board of Directors of the Company or that disclosure of
such information in the Registration Statement would be detrimental to the
business and affairs of the Company; or (b) any material engagement or activity
by the Company which would, in the good faith determination of the Chief
Executive Officer or the Board of Directors of the Company, be adversely
affected by disclosure in a registration statement at such time, which
determination shall be accompanied by a good faith determination by the Chief
Executive Officer or the Board of Directors of the Company that the Registration
Statement would be materially misleading absent the inclusion of such
information.

            SECTION 4. Cooperation with Company. Holder will cooperate with the
Company in all respects in connection with this Agreement, including timely
supplying all information reasonably requested by the Company (which shall
include all information regarding the Holder and proposed manner of sale of the
Registrable Securities required to be disclosed in the Registration Statement)
and executing and returning all documents reasonably requested in connection
with the registration and sale of the Registrable Securities and entering into
and performing its obligations under any underwriting agreement, if the offering
is an underwritten offering, in usual and customary form, with


                                       3
   32

the managing underwriter or underwriters of such underwritten offering. The
Holder consents to be named as a statutory underwriter in the Registration
Statement.

            SECTION 5. Registration Procedures. If and whenever the Company is
required by any of the provisions of this Agreement to effect the registration
of any of the Registrable Securities under the Act, the Company shall use its
best efforts (except as otherwise provided in this Agreement), as expeditiously
as possible, subject to the Holder's assistance and cooperation as reasonably
required:

            (a) (i) prepare and file with the Commission such amendments and
supplements to the Registration Statement and the prospectus used in connection
therewith as may be necessary to keep such registration statement effective and
to comply with the provisions of the Act with respect to the sale or other
disposition of all securities covered by such registration statement whenever
the Holder of such Registrable Securities shall desire to sell or otherwise
dispose of the same (including prospectus supplements with respect to the sales
of securities from time to time in connection with a registration statement
pursuant to Rule 415 promulgated under the Act) and (ii) take all lawful action
such that each of (A) the Registration Statement and any amendment thereto does
not, when it becomes effective, contain an untrue statement of a material fact
or omit to state a material fact required to be stated therein or necessary to
make the statements therein, not misleading and (B) the Prospectus forming part
of the Registration Statement, and any amendment or supplement thereto, does not
at any time during the Registration Period include an untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading.

            (b) (i) prior to the filing with the Commission of any Registration
Statement (including any amendments thereto) and the distribution or delivery of
any prospectus (including any supplements thereto), provide draft copies thereof
to the Holders and reflect in such documents all such comments as the Holders
(and their counsel) reasonably may propose and (ii) furnish to each Holder such
numbers of copies of a prospectus including a preliminary prospectus or any
amendment or supplement to any prospectus, as applicable, in conformity with the
requirements of the Act, and such other documents, as such Holder may reasonably
request in order to facilitate the public sale or other disposition of the
securities owned by such Holder;

            (c) register and qualify the Registrable Securities covered by the
Registration Statement under such other securities or blue sky laws of such
jurisdictions as the Holder shall reasonably request (subject to the limitations
set forth in Section 3(d) above), and do any and all other acts and things which
may be necessary or advisable to enable each Holder to consummate the public
sale or other disposition in such jurisdiction of the securities owned by such
Holder, except that the Company shall not for any such purpose be required to
qualify to do business as a foreign corporation in any jurisdiction wherein it
is not so qualified or to file therein any general consent to service of
process;

            (d) list such Registrable Securities on the Primary Market, and any
other exchange on which the Common Stock of the Company is then listed, if the
listing of such Registrable Securities is then permitted under the rules of such
exchange;

            (e) notify each Holder at any time when a prospectus relating
thereto covered by the Registration Statement is required to be delivered under
the Act, of the happening of any event of which it has knowledge as a result of
which the prospectus included in the Registration Statement, as then in effect,
includes an untrue statement of a material fact or omits to state a material
fact required to be stated therein or necessary to make the statements therein
not misleading in the light of the circumstances then existing, and the Company
shall prepare and file a curative amendment under Section 5(a) as quickly as
commercially possible;

            (f) as promptly as practicable after becoming aware of such event,
notify Holder (or, in the event of an underwritten offering, the managing
underwriters) of the issuance by the Commission or any state authority of any
stop order or other suspension of


                                       4
   33


the effectiveness of the Registration Statement at the earliest possible time
and take all lawful action to effect the withdrawal, recession or removal of
such stop order or other suspension;

            (g) cooperate with the Holder to facilitate the timely preparation
and delivery of certificates for the Registrable Securities to be offered
pursuant to the Registration Statement and enable such certificates for the
Registrable Securities to be in such denominations or amounts, as the case may
be, as the Holder reasonably may request and registered in such names as the
Holder may request; and, within three Trading Days after a Registration
Statement which includes Registrable Securities is declared effective by the
Commission, deliver and cause legal counsel selected by the Company to deliver
to the transfer agent for the Registrable Securities (with copies to the Holder)
an appropriate instruction and, to the extent necessary, an opinion of such
counsel;

            (h) take all such other lawful actions reasonably necessary to
expedite and facilitate the disposition by the Holder of its Registrable
Securities in accordance with the intended methods therefor provided in the
prospectus which are customary for issuers to perform under the circumstances;

            (i) in the event of an underwritten offering, promptly include or
incorporate in a Prospectus supplement or post-effective amendment to the
Registration Statement such information as the managers reasonably agree should
be included therein and to which the Company does not reasonably object and make
all required filings of such Prospectus supplement or post-effective amendment
as soon as practicable after it is notified of the matters to be included or
incorporated in such Prospectus supplement or post-effective amendment; and

            (j) maintain a transfer agent and registrar for its Common Stock.

            SECTION 6. Indemnification.

            (a) The Company agrees to indemnify and hold harmless the Holder and
each person, if any, who controls the Holder within the meaning of the
Securities Act ("Distributing Holder") against any losses, claims, damages or
liabilities, joint or several (which shall, for all purposes of this Agreement,
include, but not be limited to, all reasonable costs of defense and
investigation and all reasonable attorneys' fees), to which the Distributing
Holder 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 any untrue statement or alleged untrue statement
of any material fact contained in the Registration Statement, or any related
preliminary prospectus, final prospectus or 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; provided, however, that the Company will not
be liable 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 the Registration Statement,
preliminary prospectus, final prospectus or amendment or supplement thereto in
reliance upon, and in conformity with, written information furnished to the
Company by the Distributing Holder, specifically for use in the preparation
thereof. This Section 6(a) shall not inure to the benefit of any Distributing
Holder with respect to any person asserting such loss, claim, damage or
liability who purchased the Registrable Securities which are the subject thereof
if the Distributing Holder failed to send or give (in violation of the
Securities Act or the rules and regulations promulgated thereunder) a copy of
the prospectus contained in such Registration Statement to such person at or
prior to the written confirmation to such person of the sale of such Registrable
Securities, where the Distributing Holder was obligated to do so under the
Securities Act or the rules and regulations promulgated thereunder. This
indemnity agreement will be in addition to any liability which the Company may
otherwise have.

        Each Distributing Holder agrees that it will indemnify and hold harmless
the Company, and each officer, director of the Company or person, if any, who
controls the Company within the meaning of the Securities Act, against any
losses, claims, damages or liabilities (which shall, for all purposes of this
Agreement, include, but not be limited


                                       5
   34

to, all reasonable costs of defense and investigation and all reasonable
attorneys' fees) 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 in respect
thereof) arise out of or are based upon any untrue statement or alleged untrue
statement of any material fact contained in the Registration Statement, or any
related preliminary prospectus, final prospectus or amendment or supplement
thereto, or arise out of or are based upon the omission or the alleged omission
to state therein a material fact required to be stated therein or necessary to
make the statements therein not misleading, but in each case only to the extent
that such untrue statement or alleged untrue statement or omission or alleged
omission was made in the Registration Statement, preliminary prospectus, final
prospectus or amendment or supplement thereto in reliance upon, and in
conformity with, written information furnished to the Company by such
Distributing Holder, specifically for use in the preparation thereof. This
indemnity agreement will be in addition to any liability which the Distributing
Holder may otherwise have. Notwithstanding anything to the contrary herein, the
Distributing Investor shall not be liable under this Section 6(b) for any amount
in excess of the net proceeds to such Distributing Investor as a result of the
sale of Registrable Securities pursuant to the Registration Statement.

            (b) Promptly after receipt by an indemnified party under this
Section 6 of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against the indemnifying party
under this Section 6, notify the indemnifying party of the commencement thereof;
but the omission so to notify the indemnifying party will not relieve the
indemnifying party from any liability which it may have to any indemnified party
except to the extent of actual prejudice demonstrated by the indemnifying party.
In case any such action is brought against any indemnified party, and it
notifies the indemnifying party of the commencement thereof, the indemnifying
party will be entitled to participate in, and, to the extent that it may wish,
jointly with any other indemnifying party similarly notified, assume the defense
thereof, subject to the provisions herein stated and after notice from the
indemnifying party to such indemnified party of its election so to assume the
defense thereof, the indemnifying party will not be liable to such indemnified
party under this Section 6 for any legal or other expenses subsequently incurred
by such indemnified party in connection with the defense thereof other than
reasonable costs of investigation, unless the indemnifying party shall not
pursue the action to its final conclusion. The indemnified party shall have the
right to employ separate counsel in any such action and to participate in the
defense thereof, but the fees and expenses of such counsel shall not be at the
expense of the indemnifying party if the indemnifying party has assumed the
defense of the action with counsel reasonably satisfactory to the indemnified
party; provided that if the indemnified party is the Distributing Holder, the
fees and expenses of such counsel shall be at the expense of the indemnifying
party if (i) the employment of such counsel has been specifically authorized in
writing by the indemnifying party, or (ii) the named parties to any such action
(including any impleaded parties) include both the Distributing Holder and the
indemnifying party and the Distributing Holder shall have been advised by such
counsel that there may be one or more legal defenses available to the
indemnifying party different from or in conflict with any legal defenses which
may be available to the Distributing Holder (in which case the indemnifying
party shall not have the right to assume the defense of such action on behalf of
the Distributing Holder, it being understood, however, that the indemnifying
party shall, in connection with any one such action or separate but
substantially similar or related actions in the same jurisdiction arising out of
the same general allegations or circumstances, be liable only for the reasonable
fees and expenses of one separate firm of attorneys for the Distributing Holder,
which firm shall be designated in writing by the Distributing Holder). No
settlement of any action against an indemnified party shall be made without the
prior written consent of the indemnified party, which consent shall not be
unreasonably withheld.

        All fees and expenses of the indemnified party (including reasonable
costs of defense and investigation in a manner not inconsistent with this
Section and all reasonable attorneys' fees and expenses) shall be paid to the
indemnified party, as incurred, within ten (10) Trading Days of written notice
thereof to the indemnifying party (regardless of whether it is ultimately
determined that an indemnified party is not entitled to indemnification
hereunder; provided, that the indemnifying party may require such indemnified
party to undertake to reimburse all such fees and expenses to the extent it is
finally judicially determined that such indemnified party is not entitled to
indemnification hereunder).

   35



            SECTION 7. Contribution. In order to provide for just and equitable
contribution under the Securities Act in any case in which (i) the indemnified
party makes a claim for indemnification pursuant to Section 6 hereof but is
judicially determined (by the entry of a final judgment or decree by a court of
competent jurisdiction and the expiration of time to appeal or the denial of the
last right of appeal) that such indemnification may not be enforced in such case
notwithstanding the fact that the express provisions of Section 6 hereof provide
for indemnification in such case, or (ii) contribution under the Securities Act
may be required on the part of any indemnified party, then the Company and the
applicable Distributing Holder shall contribute to the aggregate losses, claims,
damages or liabilities to which they may be subject (which shall, for all
purposes of this Agreement, include, but not be limited to, all reasonable costs
of defense and investigation and all reasonable attorneys' fees), in either such
case (after contribution from others) on the basis of relative fault as well as
any other relevant equitable considerations. The relative fault shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged omission to state
a material fact relates to information supplied by the Company on the one hand
or the applicable Distributing Holder on the other hand, and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission. The Company and the Distributing Holder
agree that it would not be just and equitable if contribution pursuant to this
Section 7 were determined by pro rata allocation or by any other method of
allocation which does not take account of the equitable considerations referred
to in this Section 7. 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 in this Section 7 shall be deemed to include any
legal or other 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.

        Notwithstanding any other provision of this Section 7, in no event shall
any (i) Holder be required to undertake liability to any person under this
Section 7 for any amounts in excess of the dollar amount of the net proceeds to
be received by such Holder from the sale of such Holder'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) underwriter be required
to undertake liability to any person hereunder for any amounts in excess of the
aggregate discount, commission or other compensation payable to such underwriter
with respect to the Registrable Securities underwritten by it and distributed
pursuant to the Registration Statement.

            SECTION 8. Notices. All notices, demands, requests, consents,
approvals, and other communications required or permitted hereunder shall be in
writing and, unless otherwise specified herein, shall be (i) personally served,
(ii) deposited in the mail, registered or certified, return receipt requested,
postage prepaid, (iii) delivered by reputable air courier service with charges
prepaid, or (iv) transmitted by hand delivery, telegram, or facsimile, addressed
as set forth below or to such other address as such party shall have specified
most recently by written notice. Any notice or other communication required or
permitted to be given hereunder shall be deemed effective (a) upon hand delivery
or delivery by facsimile, with accurate confirmation generated by the
transmitting facsimile machine, at the address or number designated below (if
delivered on a business day during normal business hours where such notice is to
be received), or the first business day following such delivery (if delivered
other than on a business day during normal business hours where such notice is
to be received) or (b) on the second business day following the date of mailing
by reputable courier service, fully prepaid, addressed to such address, or upon
actual receipt of such mailing, whichever shall first occur. The addresses for
such communications shall be as set forth in the Purchase Agreement.

        Either party hereto may from time to time change its address or
facsimile number for notices under this Section 8 by giving at least ten (10)
days' prior written notice of such changed address or facsimile number to the
other party hereto.

            SECTION 9. Assignment. Neither this Agreement nor any rights of the
Holder or the Company hereunder may be assigned by either party to any other
person. Notwithstanding the foregoing, (a) the provisions of this Agreement
shall inure to the benefit of, and be


                                       7
   36


enforceable by, any transferee of any of the Common Stock purchased by the
Investor pursuant to the Purchase Agreement, and (b) upon the prior written
consent of the Company, which consent shall not be unreasonably withheld or
delayed in the case of an assignment to an affiliate of the Holder, the Holder's
interest in this Agreement may be assigned at any time, in whole or in part, to
any other person or entity (including any affiliate of the Holder) who agrees to
be bound hereby.

            SECTION 10. Additional Covenants of the Company. The Company agrees
that at such time as it meets all the requirements for the use of Securities Act
Registration Statement on Form S-3 it shall file all reports and information
required to be filed by it with the Commission in a timely manner and take all
such other action so as to maintain such eligibility for the use of such form.

            SECTION 11. Counterparts/Facsimile. This Agreement may be executed
in two or more counterparts, each of which shall constitute an original, but all
of which, when together shall constitute but one and the same instrument, and
shall become effective when one or more counterparts have been signed by each
party hereto and delivered to the other party. In lieu of the original, a
facsimile transmission or copy of the original shall be as effective and
enforceable as the original.

            SECTION 12. Remedies. The remedies provided in this Agreement are
cumulative and not exclusive of any remedies provided by law. If any term,
provision, covenant or restriction of this Agreement is held by a court of
competent jurisdiction to be invalid, illegal, void or unenforceable, the
remainder of the terms, provisions, covenants and restrictions set forth herein
shall remain in full force and effect and shall in no way be affected, impaired
or invalidated, and the parties hereto shall use their best efforts to find and
employ an alternative means to achieve the same or substantially the same result
as that contemplated by such term, provision, covenant or restriction. It is
hereby stipulated and declared to be the intention of the parties that they
would have executed the remaining terms, provisions, covenants and restrictions
without including any of such that may be hereafter declared invalid, illegal,
void or unenforceable.

            SECTION 13. Conflicting Agreements. The Company shall not enter into
any agreement with respect to its securities that is inconsistent with the
rights granted to the holders of Registrable Securities in this Agreement or
otherwise prevents the Company from complying with all of its obligations
hereunder.

            SECTION 14. Headings. The headings in this Agreement are for
reference purposes only and shall not affect in any way the meaning or
interpretation of this Agreement.

            SECTION 15. Governing Law, Arbitration. This Agreement shall be
governed by and construed in accordance with the laws of the State of
California. Any dispute under this Agreement shall be submitted to arbitration
under the American Arbitration Association (the "AAA") in San Francisco,
California, and shall be finally and conclusively determined by the decision of
a board of arbitration consisting of three (3) members (hereinafter referred to
as the "Board of Arbitration") selected as according to the rules governing the
AAA. The Board of Arbitration shall meet on consecutive business days in San
Francisco, California, and shall reach and render a decision in writing
(concurred in by a majority of the members of the Board of Arbitration) with
respect to the amount, if any, which the losing party is required to pay to the
other party in respect of a claim filed. In connection with rendering its
decisions, the Board of Arbitration shall adopt and follow the laws of the State
of California. To the extent practical, decisions of the Board of Arbitration
shall be rendered no more than thirty (30) calendar days following commencement
of proceedings with respect thereto. The Board of Arbitration shall cause its
written decision to be delivered to all parties involved in the dispute. The
Board of Arbitration shall be authorized and is directed to enter a default
judgment against any party refusing to participate in the arbitration proceeding
with thirty days of any deadline for such participation. Any decision made by
the Board of Arbitration (either prior to or after the expiration of such thirty
(30) calendar day period) shall be final, binding and conclusive on the parties
to the dispute, and entitled to be enforced to the fullest extent permitted by
law and entered in any court of competent jurisdiction. The prevailing party
shall be awarded its costs, including attorneys' fees, from the non-prevailing
party as part of the arbitration award. Any party shall have the right to


                                       8
   37

seek injunctive relief from any court of competent jurisdiction in any case
where such relief is available. The prevailing party in such injunctive action
shall be awarded its costs, including attorney's fees, from the non-prevailing
party.

            SECTION 16. Severability. If any provision of this Agreement shall
for any reason be held invalid or unenforceable, such invalidity or
unenforceability shall not affect any other provision hereof and this Agreement
shall be construed as if such invalid or unenforceable provision had never been
contained herein.

                             STOCK PURCHASE WARRANT


                  To Purchase 125,000 Shares of Common Stock of

                        PLANET POLYMER TECHNOLOGIES, INC.

            THIS CERTIFIES that, for value received, Triton West Group, Inc.
(the "Holder"), is entitled, upon the terms and subject to the conditions
hereinafter set forth, at any time on or February 23, 2001 (the "Initial
Exercise Date") and on or prior to the close of business on February 23, 2004
(the "Termination Date") but not thereafter, to subscribe for and purchase from
Planet Polymer Technologies, Inc., a California corporation (the "Company"), up
to one hundred twenty-five thousand (125,000) shares (the "Warrant Shares") of
Common Stock, no par value, of the Company (the "Common Stock"). The purchase
price of one share of Common Stock (the "Exercise Price") under this Warrant
shall be $2.5781 (125% of the lowest closing bid price during the Six Trading
Days immediately preceding the initial Closing Date). The Exercise Price and the
number of shares for which the Warrant is exercisable shall be subject to
adjustment as provided herein. In the event of any conflict between the terms of
this Warrant and the Private Equity Line of Credit Agreement dated August 15,
2000 pursuant to which this Warrant has been issued (the "Purchase Agreement"),
the Purchase Agreement shall control. Capitalized terms used and not otherwise
defined herein shall have the meanings set forth for such terms in the Purchase
Agreement.


                                       1
   40


            1. Title to Warrant. Prior to the Termination Date and subject to
compliance with applicable laws, this Warrant and all rights hereunder are
transferable, in whole or in part, at the office or agency of the Company by the
holder hereof in person or by duly authorized attorney, upon surrender of this
Warrant together with the Assignment Form annexed hereto properly endorsed.

            2. Authorization of Shares. The Company covenants that all shares of
Common Stock which may be issued upon the exercise of rights represented by this
Warrant will, upon exercise of the rights represented by this Warrant, be duly
authorized, validly issued, fully paid and nonassessable and free from all
taxes, liens and charges in respect of the issue thereof (other than taxes in
respect of any transfer occurring contemporaneously with such issue).

            3. Exercise of Warrant. Except as provided in Section 4 herein,
exercise of the purchase rights represented by this Warrant may be made at any
time or times on or after the Initial Exercise Date, and before the close of
business on the Termination Date, unless this Warrant is forfeited on such
earlier date pursuant to Section 2.4(b) of the Purchase Agreement. Exercise of
this Warrant or any part hereof shall be effected by the surrender of this
Warrant and the Notice of Exercise Form annexed hereto duly executed, at the
office of the Company (or such other office or agency of the Company as it may
designate by notice in writing to the registered holder hereof at the address of
such holder appearing on the books of the Company) and upon payment of the
Exercise Price of the shares thereby purchased by wire transfer or cashier's
check drawn on a United States bank, the holder of this Warrant shall be
entitled to receive a certificate for the number of shares of Common Stock so
purchased. Certificates for shares purchased hereunder shall be delivered to the
holder hereof within three (3) Trading Days after the date on which this Warrant
shall have been exercised as aforesaid. This Warrant shall be deemed to have
been exercised and such certificate or certificates shall be deemed to have been
issued, and Holder or any other person so designated to be named therein shall
be deemed to have become a holder of record of such shares for all purposes, as
of the date the Warrant has been exercised by payment to the Company of the
Exercise Price and all taxes required to be paid by Holder, if any, pursuant to
Section 5 prior to the issuance of such shares, have been paid. If this Warrant
shall have been exercised in part, the Company shall, at the time of delivery of
the certificate or certificates representing Warrant Shares, deliver to Holder a
new Warrant evidencing the rights of Holder to purchase the unpurchased shares
of Common Stock called for by this Warrant, which new Warrant shall in all other
respects be identical with this Warrant. This Warrant may also be exercised by
means of a "cashless exercise" in which the holder shall be entitled to receive
a certificate for the number of shares equal to the quotient obtained by
dividing [(A-B) (X)] by (A), where:

               (A)  =   the average of the high and low trading prices per share
                        of Common Stock on the Principal Market on the Trading
                        Day preceding the date of such election;

               (B)  =   the Exercise Price of the Warrants; and

               (X)  =   the number of shares issuable upon exercise of the
                        Warrants in accordance with the terms of this Warrant.

            4. No Fractional Shares or Scrip. No fractional shares or scrip
representing fractional shares shall be issued upon the exercise of this
Warrant. As to any fraction of a share which Holder would otherwise be entitled
to purchase upon such exercise, the Company shall pay a cash adjustment in
respect of such final fraction in an amount equal to the Exercise Price.

            5. Charges, Taxes and Expenses. Issuance of certificates for shares
of Common Stock upon the exercise of this Warrant shall be made without charge
to the holder hereof for any issue or transfer tax or other incidental expense
in respect of the issuance of such 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
shares of Common Stock 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


                                       2
   41



accompanied by the Assignment Form attached hereto duly executed by the holder
hereof; and the Company may require, as a condition thereto, the payment of a
sum sufficient to reimburse it for any transfer tax incidental thereto.

            6. Closing of Books. The Company will not close its shareholder
books or records in any manner which prevents the timely exercise of this
Warrant.

            7. Transfer, Division and Combination. (a) Subject to compliance
with any applicable securities laws, transfer of this Warrant and all rights
hereunder, in whole or in part, shall be registered on the books of the Company
to be maintained for such purpose, upon surrender of this Warrant at the
principal office of the Company, together with a written assignment of this
Warrant substantially in the form attached hereto duly executed by Holder or its
agent or attorney and funds sufficient to pay any transfer taxes payable upon
the making of such transfer. Upon such surrender and, if required, such payment,
the Company shall execute and deliver a new Warrant or Warrants in the name of
the assignee or assignees and in the denomination or denominations specified in
such instrument of assignment, and shall issue to the assignor a new Warrant
evidencing the portion of this Warrant not so assigned, and this Warrant shall
promptly be cancelled. A Warrant, if properly assigned, may be exercised by a
new holder for the purchase of shares of Common Stock without having a new
Warrant issued.

                (b) This Warrant may be divided or combined with other Warrants
upon presentation hereof at the aforesaid office of the Company, together with a
written notice specifying the names and denominations in which new Warrants are
to be issued, signed by Holder or its agent or attorney. Subject to compliance
with Section 7(a), as to any transfer which may be involved in such division or
combination, the Company shall execute and deliver a new Warrant or Warrants in
exchange for the Warrant or Warrants to be divided or combined in accordance
with such notice.

                (c) The Company shall prepare, issue and deliver at its own
expense (other than transfer taxes) the new Warrant or Warrants under this
Section 7.

                (d) The Company agrees to maintain, at its aforesaid office,
books for the registration and the registration of transfer of the Warrants.

            8. No Rights as Shareholder until Exercise. 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. Upon the surrender of this Warrant
and the payment of the aggregate Exercise Price, the Warrant Shares so purchased
shall be and be deemed to be issued to such holder as the record owner of such
shares as of the close of business on the later of the date of such surrender or
payment.

            9. Loss, Theft, Destruction or Mutilation of Warrant. The Company
covenants that upon receipt by the Company of evidence reasonably satisfactory
to it of the loss, theft, destruction or mutilation of this Warrant certificate
or any stock certificate relating to the Warrant Shares, and in case of loss,
theft or destruction, of indemnity or security reasonably satisfactory to it
(which shall not include the posting of any bond), and upon surrender and
cancellation of such Warrant or stock certificate, if mutilated, the Company
will make and deliver a new Warrant or stock certificate of like tenor and dated
as of such cancellation, in lieu of such Warrant or stock certificate.

            10. Saturdays, Sundays, Holidays, etc. 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, Sunday or a legal holiday, then such action may be
taken or such right may be exercised on the next succeeding day not a Saturday,
Sunday or legal holiday.

            11. Adjustments of Exercise Price and Number of Warrant Shares. (a)
Stock Splits, etc. The number and kind of securities purchasable upon the
exercise of this Warrant and the Exercise Price shall be subject to adjustment
from time to time upon the happening of any of the following. In case the
Company shall (i) pay a dividend in shares of Common Stock or make a
distribution in shares of Common Stock to holders of its outstanding Common
Stock, (ii) subdivide its outstanding shares of Common Stock into a greater
number of shares of Common Stock, (iii) combine its outstanding shares of Common


                                       3
   42


Stock into a smaller number of shares of Common Stock or (iv) issue any shares
of its capital stock in a reclassification of the Common Stock, then the number
of Warrant Shares purchasable upon exercise of this Warrant immediately prior
thereto shall be adjusted so that the holder of this Warrant shall be entitled
to receive the kind and number of Warrant Shares or other securities of the
Company which he would have owned or have been entitled to receive had such
Warrant been exercised in advance thereof. Upon each such adjustment of the kind
and number of Warrant Shares or other securities of the Company which are
purchasable hereunder, the holder of this Warrant shall thereafter be entitled
to purchase the number of Warrant Shares or other securities resulting from such
adjustment at an Exercise Price per Warrant Share or other security obtained by
multiplying the Exercise Price in effect immediately prior to such adjustment by
the number of Warrant Shares purchasable pursuant hereto immediately prior to
such adjustment and dividing by the number of Warrant Shares or other securities
of the Company resulting from such adjustment. An adjustment made pursuant to
this paragraph shall become effective immediately after the effective date of
such event retroactive to the record date, if any, for such event.

                (b) Reorganization, Reclassification, Merger, Consolidation or
Disposition of Assets. In case the Company shall reorganize its capital,
reclassify its capital stock, consolidate or merge with or into another
corporation (where the Company is not the surviving corporation or where there
is a change in or distribution with respect to the Common Stock of the Company),
or sell, transfer or otherwise dispose of all or substantially all its property,
assets or business to another corporation and, pursuant to the terms of such
reorganization, reclassification, merger, consolidation or disposition of
assets, shares of common stock of the successor or acquiring corporation, or any
cash, shares of stock or other securities or property of any nature whatsoever
(including warrants or other subscription or purchase rights) in addition to or
in lieu of common stock of the successor or acquiring corporation ("Other
Property"), are to be received by or distributed to the holders of Common Stock
of the Company, then either (i) Holder shall have the right thereafter to
receive, upon exercise of this Warrant, the number of shares of common stock of
the successor or acquiring corporation or of the Company, if it is the surviving
corporation, and Other Property receivable upon or as a result of such
reorganization, reclassification, merger, consolidation or disposition of assets
by a holder of the number of shares of Common Stock for which this Warrant is
exercisable immediately prior to such event or (ii) the successor or acquiring
corporation shall expressly assume the due and punctual observance and
performance of each and every covenant and condition of this Warrant to be
performed and observed by the Company and all the obligations and liabilities
hereunder, subject to such modifications as may be deemed appropriate (as
determined in good faith by resolution of the Board of Directors of the Company)
in order to provide for adjustments of shares of Common Stock for which this
Warrant is exercisable which shall be as nearly equivalent as practicable to the
adjustments provided for in this Section 11. For purposes of this Section 11,
"common stock of the successor or acquiring corporation" shall include stock of
such corporation of any class which is not preferred as to dividends or assets
over any other class of stock of such corporation and which is not subject to
redemption and shall also include any evidences of indebtedness, shares of stock
or other securities which are convertible into or exchangeable for any such
stock, either immediately or upon the arrival of a specified date or the
happening of a specified event and any warrants or other rights to subscribe for
or purchase any such stock. The foregoing provisions of this Section 11 shall
similarly apply to successive reorganizations, reclassifications, mergers,
consolidations or disposition of assets.

            12. Voluntary Adjustment by the Company. The Company may at any time
during the term of this Warrant, reduce the then current Exercise Price to any
amount and for any period of time deemed appropriate by the Board of Directors
of the Company.

            13. Notice of Adjustment. Whenever the number of Warrant Shares or
number or kind of securities or other property purchasable upon the exercise of
this Warrant or the Exercise Price is adjusted as herein provided, the Company
shall promptly mail by registered or certified mail, return receipt requested,
to the holder of this Warrant notice of such adjustment or adjustments setting
forth the number of Warrant Shares (and other securities or property)
purchasable upon the exercise of this Warrant and the Exercise Price of such
Warrant Shares (and other securities or property) after such


                                       4
   43


adjustment, setting forth a brief statement of the facts requiring such
adjustment and setting forth the computation by which such adjustment was made.
Such notice, in the absence of manifest error, shall be conclusive evidence of
the correctness of such adjustment.

            14. Notice of Corporate Action. If at any time:

                (a) the Company shall take a record of the holders of its Common
Stock for the purpose of entitling them to receive a dividend or other
distribution, or any right to subscribe for or purchase any evidences of its
indebtedness, any shares of stock of any class or any other securities or
property, or to receive any other right, or

                (b) there shall be any capital reorganization of the Company,
any reclassification or recapitalization of the capital stock of the Company or
any consolidation or merger of the Company with, or any sale, transfer or other
disposition of all or substantially all the property, assets or business of the
Company to, another corporation or,

                (c) there shall be a voluntary or involuntary dissolution,
liquidation or winding up of the Company;

then, in any one or more of such cases, the Company shall give to Holder (i) at
least 30 calendar days' prior written notice of the date on which a record date
shall be selected for such dividend, distribution or right or for determining
rights to vote in respect of any such reorganization, reclassification, merger,
consolidation, sale, transfer, disposition, liquidation or winding up, and (ii)
in the case of any such reorganization, reclassification, merger, consolidation,
sale, transfer, disposition, dissolution, liquidation or winding up, at least 30
calendar days' prior written notice of the date when the same shall take place.
Such notice in accordance with the foregoing clause also shall specify (i) the
date on which any such record is to be taken for the purpose of such dividend,
distribution or right, the date on which the holders of Common Stock shall be
entitled to any such dividend, distribution or right, and the amount and
character thereof, and (ii) the date on which any such reorganization,
reclassification, merger, consolidation, sale, transfer, disposition,
dissolution, liquidation or winding up is to take place and the time, if any
such time is to be fixed, as of which the holders of Common Stock shall be
entitled to exchange their shares of Common Stock for securities or other
property deliverable upon such disposition, dissolution, liquidation or winding
up. Each such written notice shall be sufficiently given if addressed to Holder
at the last address of Holder appearing on the books of the Company and
delivered in accordance with Section 16(d). To the extent that the notice
required to be given to Holder hereunder is material, non-public information,
then such Holder shall sign such confidentiality agreement with the Company as
it or its counsel may reasonably require to protect against the premature
disclosure of such event.

            15. Authorized Shares. The Company covenants that during the period
the Warrant is outstanding, it will reserve from its authorized and unissued
Common Stock a sufficient number of shares to provide for the issuance of the
Warrant Shares upon the exercise of any purchase rights under this Warrant. The
Company further covenants that its issuance of this Warrant shall constitute
full authority to its officers who are charged with the duty of executing stock
certificates to execute and issue the necessary certificates for the Warrant
Shares upon the exercise of the purchase rights under this Warrant. The Company
will take all such reasonable action as may be necessary to assure that such
Warrant Shares may be issued as provided herein without violation of any
applicable law or regulation, or of any requirements of the Principal Market
upon which the Common Stock may be listed.

                The Company shall not by any action, including, without
limitation, amending its certificate of incorporation or through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms of this Warrant, but will at all
times in good faith assist in the carrying out of all such terms and in the
taking of all such actions as may be necessary or appropriate to protect the
rights of Holder against impairment. Without limiting the generality of the
foregoing, the Company will (a) not increase the par value of any shares of
Common Stock receivable upon the exercise of this Warrant above the amount
payable therefor upon such exercise immediately prior to such increase in par
value, (b) take all such action as may be necessary or appropriate in order that
the Company may validly and legally issue fully paid


                                        5
   44

and nonassessable shares of Common Stock upon the exercise of this Warrant, and
(c) use all commercially reasonable efforts to obtain all such authorizations,
exemptions or consents from any public regulatory body having jurisdiction
thereof as may be necessary to enable the Company to perform its obligations
under this Warrant.

                Upon the request of Holder, the Company will at any time during
the period this Warrant is outstanding acknowledge in writing, in form
reasonably satisfactory to Holder, the continuing validity of this Warrant and
the obligations of the Company hereunder.

                Before taking any action which would cause an adjustment
reducing the current Exercise Price below the then par value, if any, of the
shares of Common Stock issuable upon exercise of the Warrants, the Company shall
take any corporate action which may be necessary in order that the Company may
validly and legally issue fully paid and non-assessable shares of such Common
Stock at such adjusted Exercise Price.

                Before taking any action which would result in an adjustment in
the number of shares of Common Stock for which this Warrant is exercisable or in
the Exercise Price, the Company shall obtain all such authorizations or
exemptions thereof, or consents thereto, as may be necessary from any public
regulatory body or bodies having jurisdiction thereof.

            16. Miscellaneous.

                (a) Jurisdiction. This Warrant shall be binding upon any
successors or assigns of the Company. This Warrant shall constitute a contract
under the laws of California without regard to its conflict of law principles or
rules, and be subject to arbitration pursuant to the terms set forth in the
Purchase Agreement.

                (b) Restrictions. The holder hereof acknowledges that the
Warrant Shares acquired upon the exercise of this Warrant, if not registered,
will have restrictions upon resale imposed by state and federal securities laws.

                (c) Nonwaiver and Expenses. No course of dealing or any delay or
failure to exercise any right hereunder on the part of Holder shall operate as a
waiver of such right or otherwise prejudice Holder's rights, powers or remedies,
notwithstanding all rights hereunder terminate on the Termination Date. If the
Company willfully fails to comply with any material provision of this Warrant,
the Company shall pay to Holder such amounts as shall be sufficient to cover any
costs and expenses including, but not limited to, reasonable attorneys' fees,
including those of appellate proceedings, incurred by Holder in collecting any
amounts due pursuant hereto or in otherwise enforcing any of its rights, powers
or remedies hereunder.

                (d) Notices. Any notice, request or other document required or
permitted to be given or delivered to the holder hereof by the Company shall be
delivered in accordance with the notice provisions of the Purchase Agreement.

                (e) Limitation of Liability. No provision hereof, in the absence
of affirmative action by Holder to purchase shares of Common Stock, and no
enumeration herein of the rights or privileges of Holder hereof, shall give rise
to any liability of Holder for the purchase price of any Common Stock or as a
stockholder of the Company, whether such liability is asserted by the Company or
by creditors of the Company.

                (f) Remedies. Holder, in addition to being entitled to exercise
all rights granted by law, including recovery of damages, will be entitled to
specific performance of its rights under this Warrant. The Company agrees that
monetary damages would not be adequate compensation for any loss incurred by
reason of a breach by it of the provisions of this Warrant and hereby agrees to
waive the defense in any action for specific performance that a remedy at law
would be adequate.

                (g) Successors and Assigns. Subject to applicable securities
laws, this Warrant and the rights and obligations evidenced hereby shall inure
to the benefit of

                                       6
   45

and be binding upon the successors of the Company and the successors and
permitted assigns of Holder. The provisions of this Warrant are intended to be
for the benefit of all Holders from time to time of this Warrant and shall be
enforceable by any such Holder or holder of Warrant Shares.

                (h) Indemnification. The Company agrees to indemnify and hold
harmless Holder from and against any liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, claims, costs, attorneys' fees, expenses
and disbursements of any kind which may be imposed upon, incurred by or asserted
against Holder in any manner relating to or arising out of any failure by the
Company to perform or observe in any material respect any of its covenants,
agreements, undertakings or obligations set forth in this Warrant; provided,
however, that the Company will not be liable hereunder to the extent that any
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
claims, costs, attorneys' fees, expenses or disbursements are found in a final
non-appealable judgment by a court to have resulted from Holder's negligence,
bad faith or willful misconduct in its capacity as a stockholder or
warrantholder of the Company.

                (i) Amendment. This Warrant may be modified or amended or the
provisions hereof waived with the written consent of the Company and the Holder.

                (j) Severability. Wherever possible, each provision of this
Warrant shall be interpreted in such manner as to be effective and valid under
applicable law, but if any provision of this Warrant shall be prohibited by or
invalid under applicable law, such provision shall be ineffective to the extent
of such prohibition or invalidity, without invalidating the remainder of such
provisions or the remaining provisions of this Warrant.

                (k) Headings. The headings used in this Warrant are for the
convenience of reference only and shall not, for any purpose, be deemed a part
of this Warrant.

SECTION 4.3

    1.  AGWAY HOLDINGS, INC. ("AGWAY"):

        a. Under the Stock Purchase Agreement dated November 12, 1998, Agway was
given a right of first refusal to purchase its pro-rata share of any Common
Stock or other Security of the Company that Planet proposed to sell or issue
after the date of the Stock Purchase Agreement. Under Section 5 (b) of this
Agreement, Planet is required to give Agway written notice of its intention,
describing the securities to be issued, the price and the terms and conditions
upon which Planet proposes to issue the securities and Agway has twenty (20)
days from that date to purchase its pro-rata share. However, under Section 5(d),
Agway may waive this right of first refusal in writing.

        b. Under the Warrant Agreement dated January 11, 1999, if Planet issues
or sells any shares of Common Stock for less than the Exercise Price (which was
$1.00), then Agway's Exercise Price shall be reduced as provided by the formula
in Section 6.4 of the Warrant Agreement.

        c. The Warrant Agreement of subsection (b) was amended by the First
Amendment to Warrant dated February 25, 1999, however, the anti-dilution
provisions were not effected.

    2. SPECIAL SITUATIONS PRIVATE EQUITY FUND, L.P.: /Special Situations holds
Series A Preferred Stock.

        a. Under the Amended and Restated Certificate of Determination of
Preferences of Series A Convertible Preferred Stock dated September 22, 1997,
Section 5(d) provides that the Conversion Price (which was $2.00 per share)
shall be adjusted if Planet issues or sells any shares of Common Stock for less
than the greater of the Conversion Price in effect prior to the issuance and
eighty-five percent (85%) of the market price on the date of such issue or sale.

        b. Under the Securities Purchase Agreement dated September 19, 1997,
there are no specific references to anti-dilution rights.

        c. Also note that Section 5(f) of the Certificate of Determination
provides that at no time shall Planet have outstanding more than an aggregate of
925,000 shares of Common Stock and/or options that were issued or granted to
management, other employees, directors or consultants as compensation. This
provision is to remain in effect until there are less than 100,000 Preferred
Shares outstanding. Thus, Planet may be unable to issue all of the shares under
the 2000 Stock Incentive Plan.

        d. Under the Warrant Agreement dated September 24, 1997, the Exercise
Price ($2.75) shall be adjusted if Planet issues or sells any shares of Common
Stock for less than the greater of the Conversion Price in effect prior to the
issuance and eighty-five percent (85%) of the market price on the date of such
issue or sale.

    3.  LBC CAPITAL RESOURCES.

        a. Under the Warrant Agreement dated March 29, 1999, Section 6.4(a)
provides that the Exercise Price ($4.1250) shall be adjusted if Planet issues or
sells any shares of Common Stock for less than the Exercise Price in effect
prior to the issuance.

        b. Under the Warrant Agreement dated March 9, 2000, Section 6.4 (a)
provides that that the Exercise Price ($4.1625) shall be adjusted if Planet
issues or sells any shares of Common Stock for less than the Exercise Price in
effect prior to the issuance.

               filed for extensions and the returns will be due September 15,
