          sufficient quantities necessary to ensure continued accuracy. This

          receipt of conforming subcontracted materials:

          *    Quality assurance surveys at its supplier's location.

          *    Satisfactory inspection and test results, or certification of

          reject, sort, hold, rework, etc.) of all purchased materials, raw
          materials, work in process, and finished materials by means of stamps,
          tags, routing cards, color codes, or other normal means.




3.   QUALITY ASSURANCE PROCESS

     3.1  MATERIALS QUALIFICATION

          Materials qualification is the process used by Recovery Engineering,
          Inc. to assure that a given supplier's material or process will
          conform to requirements in a given application.

          The process consists of these steps:

          *    Review and approval of all new engineering drawings by Purchasing
               and Design Engineering. Input from suppliers may also be
               requested during this stage of drawing review.

          *    Inspection of all prototype and sample parts by Quality Control
               Department.

          *    Reliability testing by Engineering Department.

     3.2  RECEIVING INSPECTION

          All materials received at Recovery Engineering, Inc. must pass through
          Receiving Inspection. Inspection levels vary from simple physical
          identification to complete dimensional and functional check, depending
          on past performance.

     3.3  NONCONFORMANCE REPORTING SYSTEM

          All purchased part nonconformances are documented on a Nonconformance
          Report (NMR). The information from each of these reports, along with
          the associated costs of quality, is stored in a computer database and
          used for reporting supplier quality performance. Purchased part costs
          of quality include rework labor, factory overhead, scrap, and
          paperwork and material handling costs. Should the NMR be written at
          receiving inspection, the NMR, along with a marked drawing and past
          history, is then forwarded to the Recovery Engineering, Inc.
          appropriate buyer.

     3.4  DISPOSITION OF DEFECTIVE MATERIAL

          Nonconforming material is handled in one of the following ways:

          *    Return to supplier -- this is Recovery Engineering, Inc.'s
               preferred disposition method. It will be used whenever possible.

          *    Scrap at Recovery Engineering, Inc. at supplier's expense --
               supplier will be notified prior to disposition.

          *    Rework at Recovery Engineering, Inc. at supplier's expense --
               supplier will be notified prior to reworking.

          All NMRs are required to have corrective action prior to disposition.
          All suppliers will negotiate in good faith the settlement of all cost
          incurred associated with the nonconforming parts they ship to us.

     3.5  RETURNING DEFECTIVE MATERIAL

          *    RETURN FOR REPAIR, REPLACEMENT OR CREDIT: Materials returned for
               repair,




               replacement, or credit will be accompanied by a copy of the
               Return form, which serves as the packing slip.

               The return order packing slip explains the reason for return,
               quantity returned, new purchase order number, etc.

          *    WARRANTY RETURNS: A Return form also accompanies all warranty
               materials returned to the supplier. The return order packing slip
               explains that the materials were returned from the field under
               warranty, reason for return, etc.

          Any material which is repaired and returned to Recovery Engineering,
          Inc. under the Return form must be in "as new" condition. This
          includes appearance items (painting, plating, etc.), packaging, and
          complete inspection and testing to new material specifications. No
          reference to any defect shall be on the material or package, and all
          required "loose" items (mounting hardware, clevis pin, keys, etc.)
          must be included. Material marked "rebuilt" or "reconditioned" will
          not be accepted.

     3.6  SUPPLIER CORRECTIVE ACTION

          A Corrective Action Request will be used by Recovery Engineering,
          Inc.'s Quality Group to notify suppliers of nonconformance and to
          obtain documentation as to the cause of the discrepancy and the
          corrective action taken by the supplier.

          If a score of 3 or less is received on the Quality Audit Survey, the
          supplier must provide a corrective action plan for improvement.

          Suppliers are responsible for detailing the reason for the
          nonconformance, a statement of corrective action taken to prevent the
          noncomformance from recurring, and the effective date. All requests
          must be answered on or before the date specified. All answered
          requests are reviewed by Recovery Engineering, Inc. Quality or
          Purchasing. The form will be reissued if specific corrective action is
          not specified.

ADDENDUM "C"

                          TOOLING TERMS AND CONDITIONS
                           RECOVERY ENGINEERING, INC.

INTRODUCTION

The following terms and conditions supplement those shown on the reverse side of
our Purchase Order and supersede any inconsistent provision on Purchase Orders
for the supplying of tooling by Seller to Recovery Engineering, Inc.
(REI/Buyer).

IDENTIFICATION AND MARKING

     1.0  Supplier shall identify all new tooling as designated in the tooling
          purchase order. This applies to REI owned tooling. A tool number shall
          be assigned and affixed to the tooling indicating the funding and/or
          controlling agency, i.e., Property of REI.

     2.0  Marking shall be accomplished in the appropriate manner of those
          methods listed below, unless otherwise stated on the purchase order.
          Extreme caution must be exercised so as not to damage or distort tools
          when placing identification markings on them.

          2.1  Whenever practical, the required identification should be placed
               on the tools by metal stamping. The size of the letters and
               figures used for metal stamping should be in proportion to the
               size of the tool and clearly legible.

          2.2  On hardened parts and parts that may be distorted by stamping, or
               where it is otherwise impractical to stamp, the required
               identification may be applied by etching or other means of
               permanent identification.

          2.3  Metal identification tags should be used in identifying tools
               where because of size and delicate construction, it is
               impractical to mark them otherwise. When using metals tags,
               identification data should be placed upon the metal tag and
               securely attached to the tool with a wire lead.

          2.4  When a tool consists of more than one part, individual parts
               shall be marked in accordance with 2.1, 2.2, , of 2.3 above.

PAYMENT

Upon acceptance of tooling in accordance with the paragraph below, Seller shall
submit an invoice to Buyer for payment. To qualify for payment, the invoice must
be accompanied by the following:

     1.0  A complete listing of all tools produced under the purchase order, and
          breakdown of material, labor, etc. for each tool including a copy of
          the quote and invoice from tool shop selected.

     2.0  A tool drawing of each individual tool if specified. A photo is
          optional.




EXCLUSIVE RIGHTS

Upon acceptance of tooling, in accordance with the paragraph below regarding
acceptance, and upon payment of Seller's invoice, all tooling produced under
this purchase order becomes the property of REI. Use of this tooling for any
purpose other than that authorized by Buyer is strictly prohibited.

MAINTENANCE AND INSPECTION
