accountants, engineers and other authorized representatives reasonable access
during normal business hours throughout the period prior to the Closing Date to

        10. Covenants of Buyer. Buyer covenant to Seller as set forth below:

            10.1 License. For the life of the patents included in the AQUAMIM
Technology, and in the event Buyer or its assigns decide not to supply AQUAMIM
products or services to Pacific Sintered Products, Inc., and/or Polyalloys, Inc.
and their respective successors in interest, Buyer shall provide to Seller a
limited non-royalty bearing, non-exclusive and non-transferable license for such
patents to be used only in connection with the manufacture and sale of AQUAMIM
feedstock to Pacific Sintered Products, Inc., and/or Polyalloys, Inc. and their
respective successors in interest for their internal consumption and use. The
license referred to in this Section 10.1 only includes a license for the patents
used in connection with the AQUAMIM Technology and shall not include a license
for Seller to use any tungsten-carbide feedstocks or any other feedstocks
developed by Seller for Buyer.




                                       12


            10.2 Maintenance of Records. During the Term, Buyer shall maintain
current, accurate and complete books and records relating to the Overall Sales
and the payment of the above-referenced royalties to Seller, and the performance
of its obligations under this Agreement. Seller or its designee may (at its sole
cost and expense), during the Term and for a period of twenty-four (24) months
thereafter, upon at least ten (10) days' prior written notice to Buyer and
during reasonable business hours, examine, inspect and audit such books and
records and any source documents pertaining thereto for the purposes of
verifying the accuracy and completeness of records, reports and payments
provided hereunder. Notwithstanding the foregoing, if Seller discovers during
the course of any such audit that royalty payments to Seller for any six-month
period are ninety-seven percent (97%) or less of the royalty payments that
should have been paid ("Material Discrepancy"), Seller may thereafter conduct
audits on a quarterly basis until there shall have been two (2) consecutive
years without a Material Discrepancy and Buyer shall pay all reasonable costs of
the audits. Seller or its designee may, during the course of such examination,
review or audit, make copies and/or extracts of books and records relating to
Overall Sales and royalty payments thereof and Buyer's compliance with the
provisions of this Agreement. Seller shall treat all such information reviewed
during an audit as confidential and will not disclose the same to any third
party without the written consent of Buyer.

        11. Option to Repurchase. (a) If, during the Term, Buyer decides for any
reason to vacate, close or discontinue (collectively, the "Discontinuation")
(which includes, but is not limited to, any reorganization, reconstitution,
merger, sale or consolidation where a change of control of fifty percent (50%)
or more of Buyer will occur, such that the Purchase Price for the Assets as
described in Section 2.1 herein is endangered in any way, according to the
reasonable discretion of Seller) the business associated with the use and
application of the AQUAMIM Technology and AQUAMIM Relationships , then at least
30 days before the proposed Discontinuation, Buyer shall give written notice to
Seller so that Seller may have the option to purchase the Business (the
"Option"); provided, however, a Discontinuation shall not include a sale
transaction of substantially all of the assets or capital stock of Buyer or an
initial public offering of Buyer whereby substantially all of the operations and
business of Buyer as a whole will be continued by Buyer or by the successor or
transferee of Buyer's business and/or assets. Seller shall have ten (10) days
after such notice is received to exercise the Option to purchase the Business.
If Seller does elect to exercise the Option and purchase the Business, the
parties shall determine the fair market value ("Fair Market Value") of the
Business. The procedure for determining the Fair Market Value shall be as
follows: Seller shall designate, in writing, a person to act as its appraiser
for the purpose of establishing the Fair Market Value of the Business. Within
ten (10) days after Seller gives notice of its appraiser's estimation of the
Fair Market Value, Seller and Buyer shall either reach agreement on the Fair
Market Value of the Business, or if Buyer does not agree, Buyer shall promptly
designate, in writing, a person to act as a second appraiser. If any appraiser
so designated by Seller or by Buyer shall die, be disqualified, become
incapacitated or shall fail or refuse to act before the initial Fair Market
Value shall have been determined, the party so designating such appraiser shall
designate a new appraiser. All appraisers so designated shall be independent and
shall have at least ten (10) years experience in appraising business or
companies similar to the Business. The appraiser or appraisers shall meet
promptly to determine the Fair Market Value. If, within thirty (30) days after
the designation of the second appraiser, the two (2) appraisers shall fail to
agree upon the Fair Market Value of the Business, the appraisers shall, within
ten (10) days thereafter, designate in writing a third appraiser. If the
appraisers shall fail to designate the third appraiser in the manner and the
time




                                       13


provided above, the appraiser of Buyer shall request a recognized and accredited
appraisal organization to designate a third appraiser who shall satisfy the
qualifications described above. If, within thirty (30) days after the
designation of the third appraiser, the three (3) appraisers are unable to agree
on the Fair Market Value, the Fair Market Value suggested by the two (2)
appraisers whose determination of the initial Fair Market Value are closest in
amount shall be averaged and said average shall be deemed the amount of the Fair
Market Value for purposes of determining the Fair Market Value of the Business.
The fees and expenses of the appraisers shall be borne by Seller and Buyer
equally.

            (b) The parties hereby agree and acknowledge that if Seller
purchases the Business pursuant to subsection (a), above, Buyer shall retain an
exclusive license and right to use the AQUAMIM Technology in connection with
tungsten-carbide feedstocks or feedstocks developed by Seller for Buyer. In
connection with such license as aforesaid, Buyer shall pay to Seller a six
percent (6%) royalty with respect to such sales utilizing the AQUAMIM
Technology.

        12. Sales and Use Taxes. Seller and Buyer shall each pay one-half (1/2)
of all taxes arising out of the transfer of the Assets to Buyer pursuant to this
Agreement. Seller shall file all necessary reports and other documents with the
appropriate governing bodies in California in connection with the transfer of
Assets and Seller shall pay all amounts of such taxes due in connection with the
sale and transfer of the Assets. Within 15 days after Seller has provided copies
of the transfer or sales tax returns and evidence of payment, Buyer shall
reimburse Seller for one-half (1/2) of all such taxes. Buyer shall not be
responsible for any sales, use, business, occupation, withholding or similar tax
or any taxes of any kind related to the Assets or the Business for any period
prior to the Closing Date.

        13. Indemnification; Set-Off

            13.1 Indemnification. (a) Each of the parties hereto agrees to
indemnify and hold the other (and its managers, officers, directors, members,
shareholders, employees and affiliates) harmless from and against any and all,
claims, loss, cost, liability, damage and expense (including reasonable
attorneys' fees and costs) (collectively, "claims"), arising from, in connection
with or relating to any breach of or inaccuracy in its representations,
warranties, covenants and agreements contained in this Agreement or in any
documents, instrument or agreement, executed in connection herewith.

                 (b) Seller agrees to indemnify and hold Buyer (and its
managers, members, officers, employees and affiliates) harmless from and against
any Retained Obligations. Buyer agrees to indemnify and hold Seller (and its
directors, officers, employees and affiliates) harmless from and against any
claims arising from or in connection with the operation of the Assets and the
Business subsequent to the Closing Date.

                 (c) Knowledge of the basis for a claim or of a claim at the
time of execution of this Agreement or at the Closing Date shall not waive,
limit or otherwise modify the rights and obligations of the parties as set forth
in this Section 13.

                 (d) In the event that any claim is asserted by a third party
against a party hereto as to which such party is entitled to indemnification
hereunder, such party (the "Indemnified Party") shall as promptly as possible
and in any case within 20 days after learning




                                       14


of such claim notify the party obligated to indemnify it (the "Indemnifying
Party") thereof in writing. In the event the Indemnified Party shall fail to
give notice of such claim as aforesaid, the Indemnifying Party shall not be
required to indemnify the Indemnified Party to the extent the Indemnifying Party
is prejudiced as a result of such delay in notification. The Indemnifying Party
shall have the right, upon written notice to the Indemnified Party within 10
days after receipt of its notice to conduct the defense against such claim at
its expense in its own name or, if necessary, in the name of the Indemnified
Party using counsel reasonably acceptable to the Indemnified Party. In the event
that the Indemnifying Party shall fail to give such notice, it shall be deemed
to have elected not to conduct the defense of the subject claim, and in such
event the Indemnified Party shall have the right to conduct such defense and to
compromise and settle the claim with the prior consent of the Indemnifying Party
(which shall not be unreasonably withheld). In the event that the Indemnifying
Party does elect to conduct the defense of the subject claim, the Indemnified
Party will cooperate with and make available to the Indemnifying Party such
assistance and materials as may be reasonably requested by it, all at the
expense of the Indemnifying Party, and the Indemnified Party shall have the
right at its expense to participate in the defense, provided that the
Indemnifying Party shall have the right to compromise and settle the claim only
with the prior written consent of the Indemnified Party (which shall not be
unreasonably withheld). Any judgment entered or settlement agreed upon in the
manner provided herein shall be binding upon the Indemnifying Party, and shall
conclusively be deemed to be an obligation with respect to which the Indemnified
Party is entitled to indemnification hereunder; provided, however, that any
settlement agreement or agreed order shall be subject to the prior written
consent of the Indemnified Party.

            13.2 Right of Setoff. If in the reasonable judgment of Buyer (which
judgment shall be exercised in good faith), Seller shall be indebted to Buyer
under this Agreement, including under Section 13.1, Buyer shall have the right
to setoff such indebtedness against any amount Buyer then or in the future may
owe to Seller, including without limitation amounts under the promissory notes
delivered to Seller at Closing and any royalties owed under Section 2.2, above.

        13. General Provisions.

            13.1 Jurisdiction. Each party hereto hereby consents to the

                                   EXHIBIT "F"
                              CONSULTING AGREEMENT


        This Consulting Agreement is made and entered into this ____ day of
December, 2001, by and between Ryer Industries, LLC, a Delaware limited
liability company (the "Company"), and Planet Polymer Technologies, Inc., a
California corporation ("Consultant") with respect to the following facts:


                                    RECITALS

        A. The Company desires to be assured of the association and services of
Consultant for the Company.

        B. Pursuant to that certain Purchase and Sale Agreement dated December
21, 2001 between the Company and Consultant (the "Purchase Agreement"), the
Company acquired certain assets of Consultant constituting Consultant's AQUAMIM
metal injection molding business, including certain confidential and proprietary
information ("Planet Polymer Confidential Information") related to the AQUAMIM
Technology and Relationships (as those terms are defined in the Purchase
Agreement).

        C. The Planet Polymer Confidential Information has been the subject of a
confidentiality agreement between Consultant and certain employees of
Consultant, including without limitation Dr. Robert Petcavich ("Petcavich"); and

        D. In the course of the services being rendered pursuant to this
Agreement, the Company may disclose to Consultant and to employees of
Consultant, or Consultant or its employees may observe or be exposed to,
confidential and/or proprietary trade secret information concerning the Company
and its activities, including without limitation the MIM Information (as that
term is hereinafter defined); and

        E. Consultant acknowledges that the Company would not enter into this
Agreement with Consultant, unless Consultant agrees to enter into a confidential
relationship with respect to Planet Polymer Confidential Information and the
confidential and/or proprietary information to be obtained by or disclosed to
Consultant in the course of the relationship contemplated by this Agreement.

        F. The Company desires to engage the services of Consultant to perform
for the Company certain technical consulting services and to confer with the
Managers of the Company regarding any issues arising therewith.

        G. Consultant is willing and desires to perform services for the
Company, upon the terms, covenants and conditions hereinafter set forth.


                                    AGREEMENT




        NOW, THEREFORE, in consideration of the mutual terms, covenants and
conditions hereinafter set forth, the parties agree as follows:

        1. Term and Amount of Service. The Company hereby retains Consultant for
a period of one (1) year beginning as of January 1, 2002 and continuing until
December 31, 2002 unless further extended or sooner terminated as hereinafter
provided ("Term"). Upon request by the Company, and at times mutually agreed
upon by the Company and Consultant, Consultant shall devote a maximum of eight
(8) hours per week to providing consulting services to the Company pursuant to
this Agreement. Consultation may be sought by the Company over the telephone, in
person at Consultant's office, at the Company's offices or another reasonable
location or through written correspondence. Consultant will use its best efforts
for Petcavich to perform substantially all of the consulting services to be
provided by Consultant to Company pursuant to this Agreement. In addition,
Consultant shall enter into a written agreement with Petcavich whereby Petcavich
acknowledges this Agreement and agrees to be bound by the covenants set forth in
Sections

        2. Services to Be Provided. Consultant agrees to provide consulting
services related to certain technical functions of the Company as more
specifically set forth on Exhibit "A" attached hereto and incorporated herein by
this reference. All services provided by Consultant for Company are performed
pursuant to the terms and conditions of this Agreement. Consultant's services
for Company will be limited to the specific work that Company and Consultant may
mutually agree from time to time. Consultant may elect to require that the
parties enter into a separate agreement or addendum to this Agreement for any
specific work as Consultant deems necessary.

        3. Consulting Fees. During the Term, Company shall pay or provide to
Consultant the following consulting fees:

           a. Monthly Rate. While this Agreement if in effect, Company agrees to
pay Consultant Three Thousand Five Hundred Dollars ($3,500.00) per month, paid
monthly at the beginning of each month.

           b. Expense Reimbursement. Company shall reimburse promptly Consultant
for expenses reasonable incurred in the course of carrying out Consultant's
services for the Company. The Consultant shall apply for reimbursement monthly
by submitting a completed expense reimbursement form, with receipts for all
expenditures in excess of $10.00 attached thereto.

        5. Termination. The Term shall cease only under the following
circumstances:

           a. Termination for Cause. Company shall be entitled with or without
prior notice, to terminate this Agreement for cause, in which case no consulting
fees or other fees shall be payable to Consultant after such termination.
"Cause" means Consultant's (i) gross negligence in the performance or
non-performance of any material duties to Company; (ii) commission of any
material criminal act or fraud or of any act that affects adversely the
reputation of the Company; (iii) habitual neglect of its duties that it is
required to perform under this Agreement; (iv) dishonesty; (v) failure to have
Petcavich perform substantially all of the consulting services to Company
(except





for unavailability due to reasonable and customary vacation time or sick leave)
or (vi) gross or intentional misconduct. Such termination shall not prejudice
any other remedy under law or equity of Company and the failure of Company to
terminate Consultant when cause exists shall not constitute the waiver of
Company's right to terminate this Agreement at a later time. Termination under
this section shall be considered "for cause" for purposes of this Agreement.

        6. Indemnification. In the event any person or entity who is not a party
to this Agreement makes any claim or demand, or brings any legal action,
arbitration, or other proceedings against Consultant (or its officers,
directors, employees or agents) relating to the services or work Consultant
performs for Company, Company hereby agrees to indemnify and hold Consultant
harmless from all such third party claims, or claims by Company for indemnity
regarding such third party claims, and all damages, expenses, losses, liability,
or attorneys' fees which Consultant may incur therefrom (hereinafter
collectively referred to as "liability"), except liability which results from
Consultant's negligence or Consultant's intentional torts. Company understands
that the foregoing covenant is a material inducement for Consultant to enter
this Agreement.

Petcavich and any employee of Consultant and any person or entity who comes into
possession of Confidential Information by reason of, or as a direct or indirect
consequence of, the Company's disclosure of such Confidential Information to

any software, data file or tangible object.

        8. Exclusions. Confidential Information does not include information

        9. Confidentiality. Consultant shall not disclose any of the

fees incurred or suffered by the Company as a result of a breach of this
Agreement by Consultant or any employee, agent or representative of Consultant.

        10. Required Disclosures. Employee may disclose the Company's
Confidential Information if and to the extent that such disclosure is required

opportunity to review the disclosure before it is made and to interpose its own
objection to the disclosure.

        11. Use. Consultant and any permitted additional disclosee shall use the
Confidential Information solely for the completion of its duties and services
hereunder, and shall not in any way use the Confidential Information to the
detriment of the Company, nor for any commercial purpose. Nothing in this
Agreement shall be construed as granting any rights to Consultant or to





any other person or entity, by license or otherwise, to any of the Company's
Confidential Information.

        12. Non-Solicitation of the Company's Employees. Subject to any more
restrictive covenants to which Consultant is bound, Consultant shall not,

materials shall be immediately tendered to the Company upon the earliest of any
of the following to occur: (a) upon the request of the Company at any time and
for any reason; and (b) upon termination of this Agreement. The returning of

compliance with all other terms and conditions of this Agreement, including the
obligation to keep all such Confidential Information known to Consultant in
strict confidence in accordance with Section 9, above.

        14. Relationship of the Parties. Nothing contained herein shall be
construed to place the parties in the relationship of employer/employee,

inure to the benefit of the parties hereto and their respective successors. The
rights of the Company and the Consultant hereunder may not be assigned.

        16. Severability. Should any provision of this Agreement or application
thereof be declared invalid, void or unenforceable for any reason, the validity
and binding effect of the remaining portions shall not be affected and the
remaining portions of this Agreement shall remain in full force and effect as if
this Agreement had been executed with the invalid, void or unenforceable
provision eliminated. To this end, the provisions of this Agreement are
severable.

        17. Governing Law. Except to the extent governed by the laws of the
United States, this Agreement is to be governed and construed under the internal

in San Diego County, California.





        18. Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be an original, but all of which together
shall be the same document. Such counterparts may be executed and delivered in
person or via facsimile.

        19. Entire Agreement. This Agreement and the exhibits attached hereto
constitutes the entire agreement and understanding of the parties with respect
to the subject matter hereof and supersedes all prior oral or written
agreements, arrangements, and understandings with respect thereto. No
representation, promise, inducement, statement or intention has been made by any
party hereto that is not embodied herein, and no party shall be bound by or be
liable for any alleged representation, promise, inducement, or statement not set
forth herein.

        20. Modification. This Agreement may not be modified, amended,
superseded, or cancelled, and none of the terms, covenants, representations,
warranties or conditions hereof may be waived, without a written instrument
executed by the party or parties to be bound by any such modification,
amendment, supersession, cancellation, or waiver.

        21. Attorneys' Fees and Costs. In any arbitration or other action, the
prevailing party shall be entitled to recover from the losing party its
reasonable costs and actual attorneys' fees. The "prevailing party" means the
party determined by the arbitrator to have most nearly prevailed, even if such
party did not prevail in all matters, and not necessarily the one in whose favor
a judgment is rendered.

        22. Waivers; Cumulative Remedies. The failure of any party to exercise
any of its rights hereunder or to enforce any of the terms or conditions of this
Agreement on any occasion shall not constitute or be deemed a waiver of that
party's rights thereafter to exercise any rights hereunder or to enforce any and
every term and condition of this Agreement. Any remedies provided for herein are
cumulative, and not in substitution for any other remedy any party may have at
law or in equity. No delay on the part of any party in exercising any right,
power or privilege granted hereunder shall operate as a waiver thereof, nor
shall any single or partial exercise of any such right, power or privilege
preclude any other or further exercise thereof.

        23. Representation. The parties hereto acknowledge each has read this
Agreement, that each fully understands its rights, privileges and duties under
this Agreement, and that each enters into this Agreement freely and voluntarily.
Consultant further acknowledges it has had the opportunity to consult with an
attorney of its choice who is completely independent of and in no way connected
with the Company, to explain the terms of this Agreement and the consequences of
signing it.

        24. Headings. All paragraph headings herein are inserted for convenience
only and shall not modify or affect the construction or interpretation of any
provision of this Agreement.

        25. Further Assurances. The parties agree that, from time to time
hereafter, and upon request, each of them will execute, acknowledge and deliver
such documents and other instruments and shall perform such acts and deed as may
be reasonably required or desirable to effectuate the





transactions contemplated by this Agreement or to otherwise carry out the terms
and conditions of this Agreement.
