                            SHORT TERM LOAN AGREEMENT

         This Short Term Loan Agreement ("Agreement") is made and entered into
between The Orbiter Fund ("Lender") and Automotive Performance Group, Inc., a
Delaware corporation ("Borrower") as of the 20th day of May, 1999.

                                    RECITALS

A. Borrower is in the process of attempting to conclude a certain acquisition
(the "Acquisition"). Borrower believes that this Acquisition would have
beneficial economic consequences.

B. In order to proceed to complete the Acquisition, Borrower is in need of funds
on a short term basis.

C. Lender is willing to loan (the "Loan") One Million Dollars [$1,000,000] (the
"Loan Amount") to Borrower on the terms and conditions set forth in this
Agreement.

                                  UNDERTAKINGS

1. Loan. Lender hereby agrees to make the Loan to Borrower in the Loan Amount.
Lender shall wire transfer the Loan Amount from its account in New York to
Borrower's account at a bank in New York as identified by Borrower.

2. Compensation to Lender. As compensation for making the Loan, Borrower shall
pay and deliver to Lender the following:

                                      -1-
<PAGE>   2
         2.1 The unpaid portion of the Loan Amount shall bear simple interest at
the rate of ten percent (10%) per annum ("Simple Interest") until repaid. Simple
Interest shall begin to accrue on the date the Loan Amount is wire transferred
to Borrower and shall include the date upon which payment of any portion of the
Loan Amount is actually received by Lender. Simple interest shall be computed on
a daily basis, based upon a 365-day year.

         2.2 Borrower shall issue to lender warrants to acquire One Hundred
Fifty Thousand (150,000) shares of Borrower's common stock ("Warrants") for an
exercise price of Two Dollars ($2) per common share. The terms and conditions of
these Warrants are contained in that certain "Stock Purchase Warrant," a copy of
which is attached to this Agreement as Exhibit "A." The original Stock Purchase
Warrant evidencing the Warrants shall be delivered to Lender by Borrower
concurrently with this Agreement.

         2.3 Commencing with the month of August 1999 and, if the loan amount
has not been repaid fully by August 1, 1999, continuing until the Loan Amount
and Simple Interest have been paid in full, Borrower shall issue to Lender
shares of its common stock at the rate of Twelve Thousand (12,000) common shares
per calendar month (the "Common Stock"). If the Loan Amount and all Simple
Interest are repaid in full during any calendar month, the Common Stock for that
calendar month shall be apportioned ratably over the number of days in that
calendar month and Lender shall receive only the Common Stock attributable to
the portion of the calendar month prior to full repayment.

3. Payment and Pre-Payment of Consideration. The entire Loan Amount shall be
repayable in full together with all Simple Interest on or before July 31, 1999.
The Warrants shall be issued concurrently with this Agreement. The Common Stock,
if any, to which Lender may become entitled (if at all), shall be issued at any
time and from time to time at the

                                      -2-
<PAGE>   3
end of each calendar month beginning August 31, 1999. Notwithstanding the
foregoing, Borrower shall have the absolute right to repay all or any portion of
the Loan Amount and the Simple Interest at any time, and from time to time,
without premium or penalty. All payments shall be made by wire transfer to
Lender's account in New York as Lender directs.

4. Absence of Collateral. The obligations of Borrower pursuant to this Agreement
are not secured by the assets of Borrower and repayment of the Loan Amount is an
unsecured obligation of Borrower.

5. Governing Law. This Agreement has been negotiated and entered into in the
State of New York, and shall be governed by, construed and enforced in
accordance with the internal laws of the State of New York, applied to contracts
made in New York by New York domiciliaries to be wholly performed in New York.

6. Integration. This Agreement sets forth the entire agreement between the
parties with regard to the subject matter hereof. All agreements, covenants,
representations and warranties, express and implied, oral and written, of the
parties with regard to the subject matter hereof are contained herein, in the
Exhibits hereto, and the documents referred to herein or implementing the
provisions hereof. No other agreements, covenants, representations or
warranties, express or implied, oral or written, have been made by either party
to the other with respect to the subject matter of this Agreement. All prior and
contemporaneous conversations, negotiations, possible and alleged agreements and
representations, covenants, and warranties with respect to the subject matter
hereof are waived, merged herein and therein and superseded hereby and thereby.
This is an integrated agreement.

purpose of enforcing or preventing the breach of any provision hereof,
including, but not limited to, by instituting any action or proceeding to
enforce any provision hereof, for damages by reason of any alleged breach of any
provision hereof, for a declaration of such party's rights or obligations
hereunder or for any other judicial remedy, then, if said matter is settled by
judicial determination (which term includes arbitration), the prevailing party
(whether at trial or on appeal) shall be entitled, in addition to such other
relief as may be granted, to be reimbursed by the losing party for all costs and
expenses incurred thereby, including, but not limited to, reasonable attorneys'
fees and costs for the services rendered to such prevailing party.

9. Exhibits. All Exhibits attached hereto are incorporated herein by reference
as though fully set forth herein.

foregoing, Borrower shall have the absolute right to repay all or any portion of
the Loan Amount and the Simple Interest at any time, and from time to time,

determines that it is required by any federal, state or local law, statute,
ordinance, regulation, rule or decree to withhold any amount with respect to
payment of Simple Interest, issuance of the Warrants and/or issuance of the
Common Stock, Borrower shall offset the amount of such withholding against the
Simple Interest. If the amount of any such withholding exceeds the Simple
Interest due from Borrower to Lender, Lender shall pay to Borrower the shortfall
or Borrower shall have the right to adjust the exercise price of the Warrants or
the amount of Common Stock which it is required to issue.

4. Absence of Collateral. The obligations of Borrower pursuant to this Agreement
are not secured by the assets of Borrower and repayment of the Loan Amount is an

compliance with a resolution of the Board of Directors of said corporation, duly
adopted by said Board and transcribed in full in the minutes of said
corporation. Any individual signing this Agreement on behalf of an entity
represents and warrants that he has full authority to do so. Lender represents
to Borrower that no qualification of the Warrants or the Common Stock is
required in any jurisdiction (other than the United States and the various
states within it) by reason of Lender's place of organization or manner of
conducting business. Lender will indemnify Borrower and hold Borrower harmless
against any liability, loss, cost or expense from failing to qualify or register
in any such jurisdiction.
