                                   (Unaudited)

1.        BASIS OF PRESENTATION

          The accompanying unaudited consolidated financial statements have been
     prepared in accordance with generally accepted accounting principles for
     interim financial information and with the instructions to Form 10-Q.
     Accordingly, they do not include all of the information and footnotes
     required by generally accepted accounting principles for complete financial
     statements. In the opinion of management, all adjustments necessary for a
     fair presentation, consisting only of normal recurring adjustments, have
     been included. For further information, refer to the consolidated financial
     statements contained in the Annual Report on Form 10-K for the year ended
     December 31, 1999 filed March 24, 2000.

2.        BUSINESS

          M-Wave, through its wholly-owned subsidiary Poly Circuits Inc. (the
     "Company"), manufactures high performance printed circuit boards using
     Teflon-based laminates to customers' specifications. In addition, the
     Company produces customer specified bonded assemblies consisting of a
     printed circuit board bonded in some manner to a metal carrier or pallet.
     One bonding technique used by the Company is Flexlink(TM), a patented
     process granted to the Company in 1993. The Company developed an enhanced
     version of Flexlink(TM) in 1996.

          On March 25, 1999, PC Dynamics Corporation, a subsidiary of the
     Company, sold substantially all of its machinery and equipment, inventory
     and accounts receivable and assigned all of its outstanding contracts and
     orders to Performance Interconnect Corporation, a Texas Corporation. (PIC)
     The purchase price paid by PIC consisted of:

          (i)     $893,319 in cash;

          (ii)    a promissory note in the principal amount of $773,479,
                  which is payable in nine (9) equal monthly installments
                  commencing on July 1, 1999; and

          (iii)   a promissory note in the principal amount of $293,025, which
                  is payable in monthly installments of $50,000 commencing on
                  May 1,1999 until paid. The Company has collected $293,025
                  through March 31, 2000.

     PC Dynamics and PIC also entered into a royalty agreement which provides
     for PIC to pay PC Dynamics a royalty equal to 8.5% of the net invoice value
     of certain microwave frequency components



                                      6
<PAGE>   7

     and circuit boards sold by PIC for eighteen months following the closing.
     PIC shall not be required to pay PC Dynamics in excess of $500,000 in
     aggregate royalty payments.

     In addition, PC Dynamics has leased its facility in Texas to PIC for
     $17,000 per month for three years. PIC has the right under the lease to
     purchase the facility from PC Dynamics for $2,000,000 at anytime during the
     term of the lease. If PIC exercises its right to purchase the facility, the
     remaining balance due on the royalty agreement is payable in monthly
     installments of $25,000 until a minimum of $500,000 is paid.

     This agreement was amended in the third quarter of 1999 whereas the Company
     agreed to revise the payment schedule for Promissory Note I from 9 equal
     monthly installments to 30 equal monthly installments in return for not
     pursuing the purchase of the facility in Texas. The Company has collected
     $128,088 through June 30,2000. The royalty agreement was also revised to
     $500,000 payable in equal monthly installments of $25,000 until paid. The
     Company has collected $145,000 through June 30,2000. The Company has
     received $30,000 in interest payments in second quarter of 2000. The
     Company is reviewing the possibility of selling the facility in Texas to
     PIC.

FOREIGN CURRENCY TRANSACTIONS

     All of the Company's foreign transactions are negotiated, invoiced and paid
in United States dollars.

ADDITIONAL FACTORS THAT MAY AFFECT FUTURE RESULTS

     As a supplier to microwave manufacturers, the Company is dependent upon the
success of its customers in developing and successfully marketing end-user
microwave systems. The Company is currently working on several development
programs for its customers. The development of commercial applications for
microwave systems and the timing and size of production schedules for these
programs is uncertain and beyond the control of the Company. There can be no
assurance that these development programs will have a favorable impact on the
Company's operating results. Although management believes some of these products
and programs may ultimately develop into successful commercial applications,
such developments could result in periodic fluctuations in the Company's
operating results. As a result of these considerations, the Company has
historically found it difficult to project operating results.

     The Company expects that a small number of customers will continue to
account for a substantial majority of its sales and that the relative dollar
amount and mix of products sold to any of these customers can change
significantly from year to year. There can be no assurance that the Company's
major customers will continue to purchase products from the Company at current
levels, or that the mix of products purchased will be in the same ratio. The
loss of one or more of the Company's major customers or a change in the mix of
product sales could have a material adverse effect on the Company.

     In addition, future results may be impacted by a number of other factors,
including the Company's dependence on suppliers and subcontractors for
components; the Company's ability to respond to technical advances; successful
award of contracts under bid; design and production delays; cancellation or
reduction of contract orders; the Company's effective utilization of existing
and new manufacturing resources; and pricing pressures by key customers.

     The Company's future success is highly dependent upon its ability to
manufacture products that incorporate new technology and are priced
competitively. The market for the Company's products is characterized by rapid
technology advances and industry-wide competition. This competitive environment
has resulted in downward pressure on gross margins. In addition, the Company's
business has evolved towards the production of relatively smaller quantities of
more complex products, the
