                      PURCHASE, SALE AND LICENSE AGREEMENT

                  THIS PURCHASE, SALE AND LICENSE AGREEMENT ("Agreement") is
entered into as of May 1, 2003 by and among PLANET POLYMER TECHNOLOGIES, INC., a
California corporation ("Planet"), and RYER ENTERPRISES LLC, a Nevada limited
liability company ("Ryer"), with reference to the following facts:

         A.       Planet is engaged in the business of developing and licensing
unique hydrosoluble polymer and biodegradable materials with broad applications
in the fields of agriculture and industrial manufacturing and other related
business activities; and

         B.       Planet desires to sell to Ryer, and Ryer desires to purchase
from Planet, all of Planet's Equipment (as hereinafter defined) and the AQUAMIM
Relationships (as hereinafter defined) relating to Planet's metal injection
molding feedstock business (the "Business"), which are described in more detail
in Section 1 below; and

         C.       Planet desires to license to Ryer and Ryer desires to acquire
an exclusive worldwide license from Planet to use and commercially exploit all
rights to the Intellectual Property (as hereinafter defined), which is described
in more detail in Section 3 below. It is anticipated that, as provided in
Section 3.5 below, the Intellectual Property will automatically become the
property of Ryer, without additional payment therefor, upon the expiration of
the Term (as hereinafter defined), provided that Ryer makes all of the payments
due to Planet under this Agreement.

                  NOW, THEREFORE, IN CONSIDERATION OF the foregoing facts and
the mutual promises set forth below, the parties agree as follows:

         1.       Purchase and Sale of Assets. Subject to the terms and
conditions set forth in this Agreement, Planet hereby agrees to sell to Ryer,
and Ryer hereby agrees to purchase from Planet: (a) all of Planet's Equipment (
the "Equipment") relating to the Business, which Equipment is set forth in more
detail in Exhibit "A," attached hereto and incorporated by reference; and (b)
all right, title and interest of Planet in all existing business relationships,
development projects, business development programs, existing orders and
contracts relating to the AQUAMIM Technology, if any (collectively, the "AQUAMIM
Relationships"). The Equipment and the AQUAMIM Relationships are collectively
referred to as the "Assets".

         2.       Purchase Price for the Assets. The purchase price (the
"Purchase Price") for the Assets shall consist of the following consideration:

                  2.1      Cash. Ryer shall pay Planet Three Hundred One
Thousand Dollars ($301,000.00), payable in the following installments (each a
"Principal Payment"): (a) Twenty Five Thousand Dollars ($25,000.00) on or before
May 1, 2003, and (b) Eleven Thousand Five Hundred Dollars ($11,500.00) on or
before the first day of each and every month for the period beginning June 1,
2003 through May, 31, 2005, for a period of twenty-four (24) months (the
"Period"), as set forth in more detail in the Secured Promissory Note attached
hereto as Exhibit

<PAGE>

"C" and incorporated by reference. Ryer reserves the right to pre-pay the
balance remaining on the Purchase Price and receive the benefit of the Balance
Pre-Payment Incentive as defined in Section 2.2 below.

                  2.2      Balance Pre-Payment Incentive. At any time during the
Period and so long as Ryer is not in default on any payment due Planet under
this Agreement, Ryer has the option to pre-pay the remaining balance on the
Purchase Price in full (the "Balance Pre-Payment") by paying to Planet the
discounted net present value of the remaining unpaid monthly payments determined
using a discount rate equal to the then current yield on Two Year U.S. Treasury
Bills ("T-Bill Rate"). The T-Bill rate shall be that rate published in the Wall
Street Journal on the third business day preceding the date the Balance
Pre-Payment is delivered to Planet.

                  2.3      Principal Payment Due Date. If any Monthly Principal
Payment hereunder is not paid on or before the fifth calendar day of the month
in which it becomes due, Ryer shall pay, at Planet's option, a late or
collection charge equal to ten percent (10%) of the amount of such unpaid
Monthly Principal Payment. In the event that any default under this Section 2.3
continues for more than thirty (30) days, interest shall accrue at the rate of
ten percent (10%) per year (based upon a 360-day year) on the entire outstanding
principal amount until such default is cured.

                  2.4      No Assumption of Planet Obligations. Buyer shall
assume no liability, claim or obligation (contingent or otherwise) of Planet
(the "Retained Obligations"), including without limitation the following:

                           (a)      Accounts payable, product warranty
obligations and customer deposits.

                           (b)      Any amount due and payable prior to or on
account of the period preceding the Closing Date, or any liabilities, claims or
obligations arising out of, or attributable to events, circumstances, acts or
omissions occurring prior to the Closing Date (even if asserted after the
Closing Date).

                           (c)      Any liabilities arising out of or in
connection with any employment agreement, executive compensation agreement, or
any bonus, pension, benefit, welfare, vacation, sick pay, severance, retirement,
disability, insurance, collective bargaining, deferred compensation or other
employee benefit plan or labor agreement relating to Planet employees, whether
oral or written, or any liabilities arising out of or in connection with the
termination of employment of any Planet employee.

                           (d)      Any Federal, state or local income, sales,
property, real estate or other taxes or imposts payable by Planet.

                  2.5      The Purchase Price shall be allocated to the
Equipment as set forth on Exhibit "A" attached hereto and incorporated by this
reference, and to the other assets being transferred to Ryer as provided
elsewhere in this Agreement. Seventy-Five Thousand Dollars ($75,000) of the
Purchase Price shall be allocated to the AQUAMIM Relationships and general

<PAGE>

intangibles. Each of the parties shall report this transaction for tax purposes
in accordance with such allocations.

         3.       License of Patents and Trademarks and Other Intellectual
Property. Subject to the terms and conditions of this Agreement, including the
payment of royalties to Planet as provided in this Agreement, Planet hereby
grants to Ryer an exclusive, worldwide license (the "License") to use any and
all of the patents and trademarks described on Exhibit "B" attached hereto and
incorporated by reference (the "Patents and Trademarks") and any and all other
existing intellectual property relating to Planet's AQUAMIM Metal Injection
Molding ("MIM") technology (collectively, the "AQUAMIM Technology") and any
other formulas, processes and other information and trade secrets related to the
Business (collectively the "Intellectual Property") and to develop, have
developed, make, have made, use, offer to sell and sell products using any or
all of the Intellectual Property. The License includes the right to grant
sublicenses to third parties to use some or all of the Intellectual Property to
make, use or sell products, subject to the payment of royalties to Planet as if
any such use or sale were by Ryer directly (however, Planet shall never be
entitled to receive more than one royalty for any product sold). Ryer shall
notify any sub-licensees under this section of all rights and obligations of
Ryer under this Agreement that are sublicensed to such sub-licensee, and Ryer
shall notify Planet within 30 days after the grant of any sublicense under this
section, including the name and address of any such sublicensee. Except as
expressly provided in this Agreement, the License is perpetual and irrevocable.
The License may be terminated by Planet, by written notice to Ryer, in the event
that Ryer fails to make any payment due to Planet under this Agreement and such
failure is not cured within thirty (30) days after written notice thereof is
given by Planet to Ryer; provided, however, that if there is a bona fide dispute
between the parties as to the amount of any payment due to Planet, the License
may not be terminated by Planet until and unless such payment has not been made
within thirty (30) days after the final resolution of such dispute.

                  3.1      Royalties. During the eight-year period beginning on
May 1, 2003 and ending on April 30, 2011 (the "Term"), Ryer shall pay to Planet
royalties based upon sales by Ryer to third parties during the Term of Feedstock
(as hereinafter defined) and MIM products manufactured by Ryer using any
Feedstock ("Feedstock Products"). The amount of the royalties will be determined
by the formulas set forth in this Section 3.1. The applicable formula will be
determined by: (a) whether the Feedstock is based upon Planet's water-soluble
binder system ("Water-Soluble Feedstock") or is a tungsten-carbide Feedstock
made using the AQUAMIM Technology ("Carbide Feedstock"); and (b) whether the
Feedstock is sold to a third party or used by Ryer to make a Feedstock Product
that is sold to a third party. As used herein, the term "Feedstock" shall mean a
mixture of one or more metal powders and one or more binders that is used in MIM
to make a sintered metal product and that is either a Water-Soluble Feedstock or
a Carbide Feedstock.

                           3.1.1    Royalty on Feedstock Sold to a Third Party.
The royalty on any Water-Soluble Feedstock or Carbide Feedstock sold to a third
party shall be computed by multiplying the total price of such Feedstock
(excluding taxes, shipping and handling, and similar charges) by six percent
(6%). Such total price and the Shipped Weight (as that term is hereinafter
defined) of the Feedstock sold to a third party shall be evidenced by Ryer's
invoice to such third party.

<PAGE>

                           3.1.2    Royalty on Feedstock Used by Ryer. The
royalty on any Water-Soluble Feedstock or Carbide Feedstock used by Ryer to make
a Feedstock Product shall be computed by dividing the Shipped Weight (as that
term is hereinafter defined) of such Feedstock Product by ninety-four percent
(94%), and then multiplying such quotient by the Royalty Per Pound (as
hereinafter defined) of the Feedstock used to make such Feedstock Product. The
parties acknowledge that approximately six percent (6%) of the weight of a
Feedstock is comprised of the weight of the binders, which are removed during
the debinding and sintering processes of MIM. Accordingly, the parties agree
that dividing the Shipped Weight of a Feedstock Product by 94% (i.e. by 0.94)
will yield the approximate weight of the Feedstock incorporated into such
Feedstock Product. For example, if the Shipped Weight of a Feedstock Product is
94 grams, then the weight of the Feedstock incorporated into such Product is
approximately 100 grams [94 / 0.94 = 100], comprised of 94 grams of metal
powders and 6 grams of binders.

                           3.1.3    Royalty Per Pound. Since Feedstock used by
Ryer to make Feedstock Products will not be sold to a third party, the parties
have agreed to determine a Royalty Per Pound for each Feedstock, which will be
used in computing the royalty due to Planet on Feedstock incorporated by Ryer
into Feedstock Products. The parties acknowledge that: (a) the cost to produce a
Feedstock is affected by the cost of the metal powders, the cost of the binders
and the cost of mixing the metal powders and binders to form the Feedstock; (b)
the current cost of mixing is approximately One Dollar ($1.00) per pound of
Feedstock for each time the Feedstock must be mixed (e.g. the cost of mixing for
a single-mixed Feedstock is $1.00 per pound of Feedstock and such cost for a
triple-mixed Feedstock is $3.00 per pound of Feedstock); (c) the cost of metal
powders and, to a lesser extent, binders will vary (sometimes substantially)
from time to time as market conditions change; and (d) in setting the selling
price for any Feedstock, Planet would customarily mark up the total cost of such
powders, binders and mixing by fifty percent (50%) for its gross profit.
Accordingly, the parties have agreed that the Royalty Per Pound for each
Feedstock will be adjusted periodically to reflect changes in such costs, as
more particularly hereinafter provided. The Royalty Per Pound for any Feedstock
at any given time shall be computed by multiplying the then cost per pound of
such Feedstock by one and one-half (1.5) and then multiplying such product (the
"Internal Price") by either six percent (6%) for Water-Soluble Feedstocks or ten
percent (10%) for Carbide Feedstocks. The current Royalty Per Pound for each of
certain Feedstocks that Ryer anticipates it may use to make Feedstock Products,
based on the current Internal Price of such Feedstock, is set forth on Exhibit
"G" attached hereto and incorporated by reference. The Royalty Per Pound for
each Feedstock shall be adjusted annually, on the last business day of each
April, based on the then total costs of producing such Feedstock. The costs of
metal powders shall be based upon the average cost of the metal powders
purchased by Ryer over the 30-day period directly preceding the last business
day of each April, as evidenced by invoices for such purchases. Should Ryer not
purchase any metal powders in the preceding 30-day period, the price will be
determined upon the metal powder prices reported on the last business day of
April by a mutually agreeable third party supplier of the metal powder. For
simplicity, the cost of the binders and the mixing shall be assumed to be $1.00
per pound of Feedstock for the binders and $1.00 per pound of Feedstock for each
time that a Feedstock must be mixed (e.g. $3.00 per pound of Feedstock for a
triple-mixed Feedstock). Said assumed costs shall be adjusted equitably if Ryer
can demonstrate

<PAGE>

materially lower total costs for those two items. For example, if, on April 30,
2004, the cost of the metal powders used to make Tungsten Carbide (15%) Carbide
Feedstock has increased by $2.00 per pound (to $10.00 per pound) of Feedstock
then the Royalty Per Pound for such Carbide Feedstock will become $2.10 per
pound [($10.00+$1.00+$3.00) x 1.5 x 10% = $2.10]. If, on April 30, 2004, the
cost of the metal powders used to make Tungsten Carbide (15%) Carbide Feedstock
has decreased by $2.00 per pound (to $6.00 per pound) of Feedstock, and if Ryer
has determined to double-mix the Feedstock (instead of triple-mixing it), then
the Royalty Per Pound for such Carbide Feedstock will become $1.35 per pound
[($6.00+$1.00+$2.00) x 1.5 x 10% = $1.35]. The Royalty Per Pound for any
Feedstock shall also be adjusted at such other times as there is a Material
Change in the cost of the metal powders. A Material Change is one that results
in a Twenty Five Percent (25%) or greater increase or decrease in the cost of
the metal powders.

                           3.1.4    Shipped Weight. The Shipped Weight of any
Feedstock Product shall be determined in the following manner. If fewer than
four of any identical item are shipped, the Ryer employee responsible for
shipping such items (the "Shipping Clerk") shall weigh each item and shall
determine the average weight of such items, which average weight and the total
weight of all such items (determined by multiplying the average weight by the
number of pieces of such item) shall be noted on the shipping manifest. If more
than three of any identical item are shipped, the Shipping Clerk shall weigh
three representative samples of such item and determine the average weight of
such items, which average weight and the total weight of all such items
(determined by multiplying the average weight by the number of pieces) shall be
noted on the shipping manifest. Alternatively, if a container contains only
identical Feedstock Products or Feedstock, the Shipping Clerk may determine the
total weight of the contents (exclusive of the weight of any packaging
material), which total weight shall be noted on the shipping manifest. The total
Shipped Weight of the various Feedstocks and Feedstock Products shipped, and the
Feedstock used to make each such Feedstock Product, shall be indicated on the
invoices to the purchasers of such items.

                           3.1.5    Computation and Payment of Royalties.
Royalties due from Ryer to Planet under this Section 3.1 shall be computed on
the total Shipped Weight of the various Feedstocks and Feedstock Products
shipped during each calendar month of the Term. The royalties due to Planet for
each calendar month (the "Royalty Payments"), computed in accordance with the
provisions of this Section 3.1, shall be paid by Ryer to Planet prior to the
expiration of forty-five (45) days after the end of such calendar month. The
obligation to make the Royalty Payments shall survive the expiration of the Term
and the termination of this Agreement. Ryer shall submit to Planet, with each
remittance, Ryer's computation of the Royalty Payment then due, together with
copies of shipping manifests and invoices to support such computation.

                  3.2      Royalty Payment Due Date. If any Royalty Payment, as
defined in Section 3.1 above, is not paid on or before the fifth calendar day
after it is due, Ryer shall pay, at Planet's option, a late or collection charge
equal to ten percent (10%) of the amount of such unpaid Monthly Principal
Payment. In the event that any default under this Section 3.2 continues for more
than thirty (30) days, interest shall accrue at the rate of ten percent (10%)
per year (based upon a 360-day year) on the unpaid amount until such default is
cured.

                  3.3      Enforcement of Patents and Trademarks During the
                           Term.

                           3.3.1    Notice of Potential Infringement. Each party
(the "Notifying Party") shall promptly notify the other party of any
infringement or potential infringement of any of the Patents or Trademarks or
any use or disclosure of any trade secret comprising part of the Intellectual
Property (the "Affected Intellectual Property") of which the Notifying Party
becomes aware.

                           3.3.2    Planet Option to Prosecute. Planet shall
have the first option and right to commence and prosecute litigation or other
proceedings to enforce any and all rights under the Intellectual Property. If
Planet commences any such litigation or proceedings, Planet shall, unless Planet
provides adequate notice, within any applicable statute of limitations, to Ryer
of Planet's intent to discontinue to prosecute such litigation or other
proceedings, diligently prosecute the same to final judgment or settlement;
provided, however, that Planet shall not settle any such matter without the
prior written approval of Ryer, which may be granted, withheld or conditioned in
Ryer's sole and absolute discretion.

                           3.3.3    Ryer Option to Prosecute. In the event that,
within ninety (90) days after the first to occur of: (a) Planet becomes aware of
an infringement or potential infringement of any Affected Intellectual Property;
or (b) Ryer notifies Planet of such an infringement or potential infringement;
Planet determines not to commence litigation or other proceedings to enforce
and/or protect the Affected Intellectual Property Planet shall notify Ryer in
writing of any such determination prior to the expiration of such 90-day period
and, if Planet fails to so notify Ryer, Planet shall be deemed to have
determined not to commence such litigation or other proceedings, then upon
expiration of such period or upon any such refusal, Ryer may commence and
prosecute litigation or other proceedings to enforce and/or protect the Affected
Intellectual Property. Planet shall cooperate with Ryer, as necessary, to enable
Ryer to prosecute such litigation or other proceedings. If acting to prevent the
running of any applicable statute of limitations, and after having provided
written notice to Planet of Ryer's intent to commence litigation and or other
proceedings, Ryer may commence said action prior to the running of the 90-day
period.

                           3.3.4    Recoveries. All recoveries resulting from
any such litigation or other proceedings shall be for the benefit of the party
that bore the expense of prosecuting the litigation or other proceeding until
all such expenses have been recovered and thereafter shall be allocated to
Planet to provide for recovery of its lost royalty interest and to Ryer to
provide for recovery of its lost profits.

                  3.4      Infringement Actions.

                           3.4.1    Notice. If at any time before termination of
this Agreement a claim is made or an action is brought against Ryer by a third
party alleging intellectual property or trade secret infringement attributable
to Ryer's use of the Intellectual Property, Ryer shall promptly inform Planet,
and Planet and Ryer shall confer together to find the best means of avoiding
infringement of such third party's intellectual property or of defending such
claims or

<PAGE>

action. Notwithstanding the foregoing, Ryer shall have no obligation to take or
refrain from taking any action to avoid any such infringement that would involve
any material change to any part of Ryer's production process or the cost to Ryer
of such process unless arrangements reasonably satisfactory to Ryer are made for
the payment by Planet of all costs of such change and all additional costs of
such process.

                           3.4.2    Indemnification. Planet shall, at its own
expense, defend and indemnify Ryer from and against any claim, demand,
liability, loss, cost, damage or expense (including attorney's fees and
disbursements but excluding those attorney's fees incurred by Ryer should Ryer
choose to retain separate outside counsel) incurred in connection with or
resulting from the alleged infringement of a third party's patent or other
propriety rights by reason of the use of the Intellectual Property in accordance
with this Agreement. Planet shall obtain written approval from Ryer as to
counsel selected to defend against any infringement claim or action. Approval of
said counsel will not be unreasonably withheld by Ryer.

                           3.4.3    Right of Setoff. If in the reasonable
judgment of Ryer (which judgment shall be exercised in good faith), Planet shall
be indebted to Ryer under this Agreement, including under Section 3.4, Ryer
shall have the right to setoff such indebtedness against any amount Ryer then or
in the future may owe to Planet, including without limitation amounts under the
promissory note delivered to Planet at Closing and any royalties owed under
Section 3.1, above.

                  3.5      Transfer of Intellectual Property Upon Expiration of
the Term. Provided that Ryer has paid to Planet all amounts due to Planet under
this Agreement, Planet shall transfer the Intellectual Property to Ryer upon the
expiration of the Term, without additional consideration. Prior to such
transfer: (a) Planet may not encumber, sell or otherwise transfer any of the
Intellectual Property to any party other than Ryer, and any such encumbrance,
sale or transfer shall be null and void; (b) Planet shall not disclose any of
the Intellectual Property that is not in the public domain as of the date of
this Agreement; (c) Planet shall, at its own expense, keep the Intellectual
Property in full force and effect, and shall timely file all necessary
extensions and other documents; and (d) if, at any time, Planet desires to
abandon any Intellectual Property, Planet shall notify Ryer thereof and shall,
at Ryer's request, transfer such Intellectual Property to Ryer.

         4.       Closing Date. The closing shall take place concurrently with
execution of this Agreement.

         5.       Conditions Precedent to the Closing by Ryer. The obligations
