  For Value received, the undersigned hereby jointly and severally promise
to pay to the order of:

                            Roger Rengler
                            4603 Grand Avenue

                            (818) 790-7635

The sum of five thousand dollars ($5,000) together with interest thereon at
the rate of one and a half (1.5%) per month on the unpaid balance.  Said sum
shall be paid in the following manner:

  1:    The principal shall be due and payable on September 1, 1998,

  2:    The note shall accrue interest at 1.5% per month payable monthly,

  3:    In consideration for the loan, the holder of the note shall have
the option to convert the balance or any portion thereof, into an equivalent
amount of common stock of the company calculated at a conversion price of
twenty percent (20%) below market value or forty cents ($0.40), whichever
results in a lower purchase price.  The company's common stock (OTC: QGRP) is
traded under the name THE QUARTZ GROUP, INC., a manufacturer of quartz glass
products for the semiconductor industry.  The shares issued in connection with
this bridge loan agreement will be subject to Rule 144 restrictions.  (One
year hold from date of conversion.)

At the investor's option, the bridge loan can be rolled over for a further
ninety (90) day period on the same terms, or roll over a portion of the bridge
loan and receive cash or stock for the balance.

SECURITY:     The loan shall be secured by the receivables of the Company.  The
Quartz Group, Inc. currently has outstanding receivables of $207,766 or which
$132,107 are within 60 days.  The company shall at all times during the term
of the loan maintain a "double coverage" of the loan balance with "current
receivables", that which has an aging of less than sixty (60) days.  If at any
time during the term of the loan the company's receivables should drop below
this double coverage level, the company would repay sufficient principal to
correct the balance.

  In the event of default, the company shall assign receivables in an
amount equal to the outstanding balance of the loan at that time of the
default.
