        THE SECURITIES REPRESENTED HEREBY HAVE BEEN ACQUIRED FOR INVESTMENT AND
        HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED.
        THESE SECURITIES MAY NOT BE OFFERED, SOLD OR TRANSFERRED ABSENT SUCH
        REGISTRATION OR AN EXEMPTION THEREFROM UNDER SAID ACT.


                        PLANET POLYMER TECHNOLOGIES, INC.
                     WARRANT TO PURCHASE UP TO A MAXIMUM OF
                          50,000 SHARES OF COMMON STOCK


        In consideration of the sum of good and valuable consideration, the
receipt of which is hereby acknowledged by PLANET POLYMER TECHNOLOGIES, INC., a
California corporation (the "Company"), LBC CAPITAL RESOURCES, INC., (the
"Holder"), is hereby granted the right to purchase at any time from the date
hereof until 5:00 p.m., Pacific Standard Time, on March 20, 2006 (the "First
Expiration Date") up to all or any part of Fifty Thousand (50,000) fully paid
and non-assessable shares of the Company's common stock, without par value
("Common Stock").

        1. EXERCISE OF WARRANT. This Warrant is exercisable at a price of
$4.1625 per share of Common Stock issuable hereunder (the "Exercise Price")
payable in cash or by certified or official bank check. Upon surrender of this
Warrant, together with a subscription form substantially in the form of "Exhibit
A" hereto duly executed, together with payment of the Exercise Price for the
shares of Common Stock purchased, at the principal executive offices of the
Company, 9985 Business Park Avenue, Suite A, San Diego, California, 92131, or at
such other office as the Company may designate by notice in writing, the Holder
shall be entitled to receive, as promptly as practicable after surrender of the
Warrant, a certificate or certificates for the shares of Common Stock so
purchased. Upon exercise of this Warrant as set forth in the preceding sentence,
the Holder shall be deemed to be the holder of record of the shares of Common
Stock issuable upon such exercise.

The purchase rights represented by this Warrant are exercisable at the option of
the Holder hereof, in whole or in part (but not as to fractional shares of the
Common Stock), during any period in which this Warrant may be exercised as set
forth above. In the case of the purchase of less than all the shares of Common
Stock purchasable under this Warrant, the Company shall cancel this Warrant upon
the surrender hereof and shall execute and deliver a new Warrant of like kind
for the balance of the shares of Common Stock purchasable hereunder.

        2. ISSUANCE OF STOCK CERTIFICATES. The issuance of certificates for
shares of Common Stock upon the exercise of this Warrant shall be made without
charge to the Holder hereof of any tax which may be payable in respect to the
issuance thereof, and such certificates shall (subject to the provisions of
Sections 3 and 5 hereof) be issued in the name of, or in such names as may be
directed by, the Holder hereof; provided, however, that the Company shall not be
required to pay any tax which may be payable in respect to any transfer involved
in the issuance and delivery of any such certificate in a name other than that
of the Holder and the Company shall not be required to issue or deliver such
certificates unless or until the person or




                                       1
<PAGE>   2

persons requesting the issuance thereof shall have paid to the Company the
amount of such tax or shall have established to the satisfaction of the Company
that such tax has been paid, and provided that the issuance of certificates for
such shares of Common Stock shall not violate the securities laws.

        3. TRANSFER, DIVISION AND COMBINATION.

           3.1 Transfer. Subject to compliance with Section 8, the Holder of
this Warrant may transfer this Warrant at any time to any subsidiary or
affiliate of the Holder. 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 or the office or agency designated by the Company,
together with a written assignment of this Warrant substantially in the form of
Exhibit B 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, subject
to Section 8, execute and deliver a new Warrant or Warrants in the name of the
assignee or assignees and in the denomination 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 in compliance with Section 8, may be exercised by
a new Holder for the purchase of shares of Common Stock without having a new
Warrant issued.

           3.2 Division and Combination. Subject to Section 8, this Warrant may
be divided or combined with other Warrants upon presentation hereof at the
aforesaid office or agency 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
3.1 and with Section 8, 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.

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

           3.4 Maintenance of Books. The Company agrees to maintain, at its
aforesaid office or agency, books for the registration and the registration of
transfer of the Warrants.

        4. EXERCISE PRICE. The exercise price of this Warrant shall be $4.1625
per share of Common Stock.

        5. REGISTRATION AND REGISTRATION RIGHTS.

           5.1 Restricted Securities. The shares of Common Stock issuable upon
exercise of this Warrant (the "Warrant Shares") have not been registered under
the Securities Act of 1933, as amended (the "Securities Act").

           5.3 Company Registration.

               (a) If the Company at any time proposes to file on its behalf
and/or on behalf of any of its security holders (the "demanding security
holders") a registration statement under the Securities Act on any form (other
than a Registration Statement on Form S-4 or S-8 or any successor form for
securities to be offered in a transaction of the type referred to in Rule 145
under the Securities Act or to employees of the Company pursuant to any employee
benefit plan, respectively) for the general registration of securities to be
sold for cash with respect to its Common Stock or any other class of equity
security (as defined in Section 3(a)(11) of the Exchange Act) of the Company, it
will give written notice to all holders of Warrants or Warrant Stock at least
ten (10) days before the initial filing with the Commission of such registration
statement, which notice shall set forth the intended method of disposition of
the securities proposed to be registered by the Company. The notice shall offer
to include in such filing the aggregate number of shares of Warrant Stock, and
the number of shares of Common Stock for which this Warrant is exercisable, as
such holders may request.

               (b) Each holder of any such Warrants or any such Warrant Stock
desiring to have Warrant Stock registered under this Section 5.3 shall advise
the Company in writing within ten (10) days after the date of receipt of such
offer from the Company, setting forth the amount of such Warrant Stock for which
registration is requested. The Company shall thereupon include in such filing
the number of shares of Warrant Stock for which registration is so requested,
subject to the paragraph 5.3 (c) below, and shall use its best efforts to effect
registration under the Securities Act of such shares.

               (c) If the registration of which the Company gives notice is for
a registered public offering involving an underwriting, the Company shall so
indicate in the notice given pursuant to Section 5.3(a). In such event the right
of any Holder to registration pursuant to this Section 5.3 shall be conditioned
upon such Holder's agreeing to participate in such underwriting and in the
inclusion of the securities of the Holder to be so registered in the
underwriting to the extent provided herein. All Holders proposing to distribute
their securities through such underwriting shall (together with the Company and
the other holders distributing their securities through such underwriting) enter
into an underwriting agreement in customary form with the underwriter or
underwriters selected for such underwriting by the Company. Notwithstanding any
other provision of this Section 5.3, if the underwriter determines that
marketing factors require a limitation of the number of shares to be
underwritten, the underwriter may exclude some or all of the securities of the
Holders from such registration and underwriting (hereinafter an "Underwriter
Cutback"). In the event of an Underwriter Cutback, the Company shall so advise
the Holders distributing their securities through such underwriting, and the
number of Registrable Securities that may be included in the registration and
underwriting shall be allocated among the Holder in proportion, as nearly as
practicable, to the respective amounts of Registrable Securities held by such
Holders at the time of filing the registration statement; provided that in no
event shall the Company be required to include in the registration less than one
thousand (1,000) shares held by any Holder. If any Holder disapproves of the
terms of any such underwriting, such Holder may elect to withdraw therefrom by
written notice to the Company and the underwriter. Any securities excluded or
withdrawn from such underwriting




                                       4
<PAGE>   5

shall be withdrawn from such registration. Except as otherwise provided in
Section 5.5, all expenses of such registration shall be borne by the Company.

           5.4 Furnish Information. It shall be a condition precedent to the
obligations of the Company to take any action pursuant to Section 5 that the
Holders shall furnish to the Company such information regarding them, the
Registrable Securities held by them, and the intended method of disposition of
such securities as the Company shall reasonably request and as shall be required
in connection with the action to be taken by the Company.

           5.5 Company Registration Expenses. All expenses incurred in complying
with Section 5, including, without limitation, all registration and filing fees,
printing expenses, fees and disbursements of counsel for the Company, the
reasonable fees and expenses of one counsel for the selling security holders
(selected by those holding a majority of the shares being registered), expenses
of any special audits incident to or required by any such registration and
expenses of complying with the securities or blue sky laws of any jurisdictions
pursuant of Section 5, shall be paid by the Company, except that the Company
shall not be liable for any fees, discounts or commissions to any underwriter or
any fees or disbursements of counsel for any underwriter in respect of the
securities sold by such Holder of Warrant Stock.

           5.6 Delay of Registration. No Holder shall have any right to take any
action to restrain, enjoin, or otherwise delay any registration as the result of
any controversy that might arise with respect to the interpretation or
implementation of this Section 5.

           5.7 Indemnification. In the event any Registrable Securities are
included in a registration statement under Section 5:

               (a) To the extent permitted by law, the Company will indemnify
and hold harmless each Holder, each of such Holder's directors and officers and
each other person who is requesting or joining in a registration, any
underwriter (as defined in the Securities Act) for it, and each other person, if
any, who controls such Holder or underwriter within the meaning of the
Securities Act, against any losses, claims, damages, or liabilities, joint or
several, to which they 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 on any untrue or alleged untrue statement of
any material fact contained in such registration statement, including any
preliminary prospectus or final prospectus contained herein or any amendments or
supplements thereto, or arise out of or are based upon the omission or alleged
omission to state therein a material fact required to be stated herein, or
necessary to make the statements therein not misleading or arise out of any
violation by the Company of any rule or regulation promulgated under the
Securities Act applicable to the Company and relating to action or inaction
required of the Company in connection with any such registration; and will
reimburse each such Holder, director, officer, participating person,
underwriter, or controlling person for any legal or other expenses reasonably
incurred by them in connection with investigating or defending any such loss,
claim, damage, liability, or action; provided, however, that the indemnity
agreement contained in this Section 5.7(a) shall not apply to amounts paid in
settlement of any such loss, claim, damage, liability, or action if such
settlement is effected without the consent of the Company nor shall the Company
be liable in any such case for any




                                       5
<PAGE>   6

such loss, claim, damage, liability, or action to the extent that it arises out
of or is based upon an untrue statement or alleged untrue statement or omission
or alleged omission made in connection with such registration statement,
preliminary prospectus, final prospectus, or amendments or supplements thereto,
in reliance upon and in conformity with written information furnished expressly
for use in connection with such registration by any such Holder, director,
officer, other participating person, underwriter, or controlling person. Such
indemnity shall remain in full force and effect regardless of any investigation
made by or on behalf of such Holder or such director, officer participating
person underwriter or controlling person, and shall survive the transfer of such
Securities by such Holder.

               (b) To the extent permitted by law, each Holder requesting or
joining in a registration will indemnify and hold harmless the Company, each of
its directors each of its officers who has signed the registration statement,
each person, if any, who controls the Company within the meaning of the
Securities Act, and each agent and any underwriter for the Company (within the
meaning of the Securities Act) against any losses, claims, damages, or
liabilities to which the Company or any such director, officer, controlling
person, agent, or underwriter may become subject, under the Securities Act or
otherwise, insofar as such losses, claims, damages, or liabilities (or actions
in respect thereto) arise out of or are based upon any untrue statement or
alleged untrue statement of any material fact contained in such registration
statement, including any preliminary prospectus or final prospectus contained
herein or any amendments or supplements 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,
in each case to the extent, but only to the extent, that such untrue statement
or alleged untrue statement or omission or alleged omission was made in such
registration statement, preliminary or final prospectus, or amendments or
supplements thereto, in reliance upon and in conformity with written information
furnished by such Holder expressly for use in connection with such registration;
and each such Holder will reimburse any legal or other expenses reasonably
incurred by the Company or any such director, officer, controlling person,
agent, or underwriter in connection with investigating or defending any such
loss, claim, damage, liability, or action; provided, however, that the indemnity
agreement contained in this Section 5.7 (b) shall not apply to amounts paid in
settlement of any such loss, claim, damage, liability, or action if such
settlement is effected without the consent of such Holder (which consent shall
not be unreasonably withheld).

               (c) Promptly after receipt by an indemnified party under this
section of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against any indemnifying party
under this section, notify the indemnifying party in writing of the commencement
thereof and the indemnifying party shall have the right to participate in and,
to the extent the indemnifying party so desires, jointly with any other
indemnifying party similarly noticed, to assume the defense thereof with counsel
mutually satisfactory to the parties. The failure to notify an indemnifying
party promptly of the commencement of any such action, if prejudicial to his
ability to defend such action, shall relieve such indemnifying party of any
liability to the indemnified party under this section, but the omission so to
notify the indemnifying party will not relieve him of any liability that he may
have to any indemnified party otherwise than under this section.

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

               (a) make and keep public information available, as those terms
are understood and defined in Rule 144, at all times subsequent to the date
hereof;

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

               (c) furnish to any Holder so long as such Holder owns any of the
Registrable Securities forthwith upon request a written statement of the Company
that it has complied with the reporting requirements of rule 144, and of the
Securities Act and the Exchange Act (at any time after it has become subject to
such reporting requirements), a copy of the most recent annual or quarterly
report of the Company, and such other reports and documents so filed by the
Company as may be reasonably requested in availing any Holder of any rule or
regulation of the Commission permitting the selling of any such securities
without registration.

           5.9 Lockup Agreement. In consideration for the Company agreeing to
its obligations under this Section 5, each Holder agrees in connection with any
registration of the Company's securities that, upon the request of the Company
or the underwriters managing any underwritten offering of the Company's
securities, not to sell, make any short sale of, loan, grant any option for the
purchase of, or otherwise dispose of any Warrants or Warrant Stock (other than
those included in the registration) without the prior written consent of the
Company or such underwriters, as the case may be, for such period of time (not
to exceed one hundred eighty (180) days) from the effective date of such
registration as the Company or the underwriters may specify.

        6. ADJUSTMENTS OF PURCHASE PRICE AND NUMBER OF SHARES.

           6.1 Subdivision and Combination. In case the Company shall at any
time subdivide or combine the outstanding shares of Common Stock, the Exercise
Price shall forthwith be proportionately decreased in the case of subdivision or
increased in the case of combination.

           6.2 Adjustment in Number of Shares. Upon each adjustment of the
Exercise Price pursuant to the provisions of this Section 6 (including 6.4
through 6.7 below), the number of shares of Common Stock issuable upon the
exercise of each Warrant shall be adjusted to the nearest full share of
multiplying the Exercise Price in effect immediately prior to such adjustment by
the number of shares of Common Stock issuable upon exercise of the Warrant
immediately prior to such adjustment and dividing the product so obtained by the
adjusted Exercise Price.

           6.3 Anti-Dilution Provisions. The Exercise Price in effect at any
time and the number and kind of securities purchasable upon the exercise of this
Warrant shall also be subject




                                       7
<PAGE>   8

to adjustment from time to time upon the happening of any of the events set
forth in Sections 6.4 through 6.7.

           6.4 In the event the Company shall issue or sell any shares of Common
Stock (except as provided in Section 6.7) for a consideration per share less
than the Exercise Price in effect immediately prior to such issue or sale, then
the Exercise Price in effect immediately prior to such issue or sale shall be
reduced to such lesser price (calculated to the nearest cent) as shall be
determined by multiplying the Exercise Price in effect immediately prior thereto
by a fraction, the numerator of which shall be the sum of: (i) the number of
shares of Common Stock outstanding immediately prior to the issuance or sale of
such additional share; and (ii) the number of shares of Common Stock which the
aggregate consideration received for the issuance or sale of such additional
shares would purchase at the Exercise Price then in effect, and the denominator
of which shall be the number of shares of Common Stock outstanding immediately
after the issuance or sale of such additional shares. For purposes of this
Section, all shares of Common Stock issuable upon exercise of outstanding
options and warrants, and all shares of Common Stock issuable upon exercise of
this Warrant, shall be deemed to be outstanding.

           6.5 For the purposes of Section 6.4 above, the following
subparagraphs (a) to (d), inclusive, shall be applicable:

               (a) If at any time the Company shall issue or sell any rights to
subscribe for, or any rights or options to purchase, Common Stock or any stock
or other securities convertible into or exchangeable for Common Stock (such
convertible or exchangeable stock or securities being hereinafter called
"Convertible Securities"), whether or not such rights or options or the right to
convert or exchange any such Convertible Securities shall be immediately
exercisable, and the price per share for which Common Stock shall be issuable
upon the exercise of such rights or options or upon conversion or exchange of
such Convertible Securities (determined by dividing: (1) the total amount, if
any, received or receivable by the Company as consideration for the granting of
such rights or options, plus the minimum aggregate amount of additional
consideration payable to the Company upon the exercise of such rights or
options, plus, in the case of any such rights or options which shall relate to
Convertible Securities, the minimum aggregate amount of additional
consideration, if any, payable upon the issue or sale of such Convertible
Securities and upon the conversion or exchange thereof, by (2) the total number
of shares of Common Stock issuable upon the exercise of such rights or options
or upon the conversion or exchange of all such Convertible Securities issuable
upon the exercise of such rights or options) shall be less than the Exercise
Price in effect immediately prior to the time of the issue or sale of such
rights or options, then the total number of shares of Common Stock issuable upon
the exercise of such rights or options or upon conversion or exchange of the
total amount of such Convertible Securities issuable upon the exercise of such
rights or options shall (as of the date of granting of such rights or options)
be deemed to be outstanding and to have been issued for such price per share,
and except as provided in Section 6.6, no further adjustments of the Exercise
price shall be made upon the actual issue of such Common Stock or of such
Convertible Securities, upon the exercise of such rights or upon the actual
issue of such Common Stock upon conversion or exchange of such Convertible
Securities.




                                       8
<PAGE>   9

               (b) If at any time the Company shall issue or sell or any
Convertible Securities, whether or not the rights to exchange or convert
thereunder shall be immediately exercisable, and the price per share for which
Common Stock shall be issuable upon such conversion or exchange (determined by
dividing (1) the total amount received or receivable by the Company as
consideration for the issue and sale of such Convertible Securities, plus the
minimum aggregate amount of additional consideration, if any payable to the
Company upon the conversion or exchange thereof, by (2) the total number of
shares of Common Stock distributable upon the conversion or exchange of all such
Convertible Securities) shall be less than the Exercise Price in effect
immediately prior to the time of such issue or sale, and the total number of
shares of Common Stock issuable upon conversion or exchange of all such
Convertible Securities shall (as of the date of the issue or sale of such
Convertible Securities) be deemed to be outstanding and to have been issued for
such price per share, and, except as provided in Section 6.6 no further
adjustments of the Exercise Price shall be made upon the actual issue of such
Common Stock upon conversion or exchange of such Convertible Securities. In
addition, if any issue or sale of such Convertible Securities shall be made upon
exercise of any rights to subscribe for or to purchase or any option to purchase
any such Convertible Securities for which adjustments of the Exercise Price
shall have been or shall be made pursuant to other provisions of this Section
6.5, no further adjustments with the Exercise Price shall be made by reason of
such issue or sale.

               (c) If at any time any shares of Common Stock or Convertible
Securities or any rights or options to purchase any such Common Stock or
Convertible Securities shall be issued or sold for cash, the consideration
received therefore shall be deemed to be the amount actually received by the
Company therefore, after deduction therefrom of any expenses incurred or any
underwriting commissions or concessions or discounts paid or allowed by the
Company in connection therewith. In case any shares of Common Stock or
Convertible Securities or any rights or options to purchase any such Common
Stock or Convertible Securities shall be issued or sold for a consideration
other than cash, the amount of the consideration other than cash actually
received by the Company shall be deemed to be the fair value of such
consideration as determined by the Board of Directors, after deduction therefrom
of any expenses incurred or any underwriting commission or concessions or
discounts paid or allowed by the Company in connection therewith. In case any
shares of Common Stock or Convertible Securities or any rights or options to
purchase any such Common Stock or Convertible Securities shall be issued in
connection with any merger or another corporation into the Company, the amount
of consideration therefore shall be deemed to be the greater of the fair market
value of the shares issued in connection with the merger after taking into
account the effects of the merger or the fair market value of the net assets of
such merged corporation as determined by the Board of Directors after deducting
therefrom all cash and other consideration (if any) paid by the Company in
connection with such merger.

               (c) The number of shares of Common Stock outstanding at any given
time shall not include shares owned or held by or for the account of the
Company, provided that such shares are neither issued, sold or otherwise
distributed by the Company.

           6.6 If the purchase or exercise price provided for in any right or
option referred to in




                                       9
<PAGE>   10

Section 6.5, or the rate at which any Convertible Securities referred to in
Section 6.5(a) or (b) shall be convertible into or exchangeable for Common
Stock, shall change or a different purchase or exercise price or rate shall
become effective at any time or from time to time (including any change
resulting from termination of such right, option or convertible security), the,
upon such change becoming effective, the Exercise Price then in effect hereunder
shall forthwith be increased or decreased to such Exercise Price as would have
been obtained had the adjustments made upon the granting or issuance of such
rights or options or Convertible Securities been made upon the basis of: (a) the
issuance of the number of shares of Common Stock theretofore actually delivered
upon the exercise of such options or rights or upon the conversion or exchange
of such Convertible Securities for the considerations received therefore; and

if any, received by the Company therefor and to be received on the basis of such
changed price.

           6.7 The Company shall not be required to make any adjustment to the
Exercise Price in the case of:

               (a) the granting, after the date hereof, by the Company of stock
options under the Company's 1995 Stock Option Plan and 2000 Stock Incentive
Plan, so long as the shares of Common Stock underlying such options are covered
by the One Million (1,000,000) shares currently reserved for issuance under such
Plans as of the date hereof; or

               (b) the issuance of shares of Common Stock, pursuant to the
exercise of the options referred to in Section 6.7 (a) above; and

any, of any options, warrants, preferred stock, convertible securities or other
rights to purchase Common Stock which options, warrants, preferred stock,
convertible securities or other rights are issued and outstanding on the date
hereof.

           6.8 Reclassification, Consolidation, Merger, Etc., In case of any

a change in par value to no par value, or from no par value to par value, or as
a result of a subdivision or combination), or in the case of any consolidation

and which does not result in any reclassification or change of the outstanding
shares of Common Stock, except a change as a result of a subdivision or
combination of such shares or conveyance to another corporation of the property
of the Company as an entirety), the Holder of this Warrant shall thereafter have
the right to purchase the kind and number of shares of stock and other
securities and property receivable upon such reclassification, change,
consolidation, merger, sale or conveyance at an aggregate price equal to the
product of: (x) the number of shares issuable upon exercise of this Warrant and

shareholders for the election of directors or any other matter, or as having any
rights whatsoever as a shareholder of the Company.

        14. NOTICES. All notices, requests, consents and other communications

being entitled to exercise all rights granted by law, including recovery of
damages, will be entitled to specific performance of its rights under Section 5
of this Warrant. The Company agrees that monetary damages would not be adequate

of Section 5 of this Warrant and hereby agrees to waive the defense in any
action for specific performance that a remedy at law would be adequate.

therein) without the prior written consent of the Holder thereof.

        17. 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
provision or the remaining provisions of this Warrant.

warranties contained in this Warrant shall bind the parties hereto and their
respective heirs, executors, administrators, distributees, successors and
