         This Loan Agreement (this "Agreement") is entered into as of this 17th
day of January, 1997 by and between Western Power & Equipment Corp. (the
"Company"), an Oregon corporation with its principal offices located at Suite
200, 4601 N.E. 77th Avenue, Vancouver, Washington 98662, and Case Credit
Corporation (the "Lender"), a Delaware corporation with its principal offices at
233 Lake Avenue, Racine, Wisconsin 53404.

         Subject to the terms and conditions of this Agreement, the Lender has
agreed to make available to the Company certain term loans, the proceeds of
which will be used by the Company solely to purchase certain assets from
Sahlberg Equipment, Inc.

                                      ARTICLE I

                                   LOANS AND NOTES

         1.1   TERM LOANS.  At any time on or prior to January 17, 1997, and
subject to all of the terms and conditions of this Agreement, the Company may
obtain two term loans (the "Loans") from the Lender in amounts which in the
aggregate shall equal [the purchase price paid by the Company for the Purchased
Assets pursuant to the terms and conditions of the Asset Purchase Agreement],
but which in no event shall be more than $5,266,392.00.  The Loans shall be
evidenced by promissory notes (the "Notes") payable to the order of the Lender
in the principal amounts advanced, dated as of the date that the loans are made
to the Company, in the forms of Exhibits A-1 and A-2 attached hereto,
respectively.  The Notes shall be executed by the Company and delivered to the
Lender prior to or simultaneously with the making of the Loans.

         1.2   USE OF PROCEEDS.  The Company represents, warrants and agrees
that the proceeds of the Loans made hereunder will be used solely for the
purchase by the Company of the Purchased Assets from Sahlberg Equipment, Inc.
pursuant to the terms of the Asset Purchase Agreement.

         1.3   OPTIONAL PREPAYMENT.  The Notes may be prepaid in whole or in
part at the option of the Company without premium or penalty.  Prepayment shall
be applied first to any accrued and unpaid interest on the Note with respect to
which the prepayment 



is made and, second, to the principal balance of such Note in inverse order of
maturity.

         1.4   COMPUTATIONS; NON-BUSINESS DAYS.  All interest payable on the
Notes shall be computed for the actual number of days elapsed, using a daily
rate determined by dividing the annual rate by 360.  Whenever any payment to be
made hereunder or under the Notes shall be stated to be due on a Saturday,
Sunday or a public holiday under the laws of the State of Wisconsin, such
payment may be made on the next succeeding business day, and such extension of
time shall be included in the computation of interest under the Notes.

                                      ARTICLE II

                               CONDITIONS OF BORROWING
