         THIS AGREEMENT R A STRATEGIC OPERATING ALLIANCE (the "Agreement") is
made this 28th day of January 2004 by and between American Standard Circuits,
Inc., an Illinois corporation ("American Standard"), with a principal place of
business at 3615 Wolf Road, Franklin Park, Illinois, and M-Wave, Inc., a
Delaware corporation ("M-Wave"), with a principal place of business at 475
Industrial Drive, West Chicago, Illinois. American Standard and M-Wave may be
referred to herein individually as a "Party" and collectively as the "Parties."

                                    RECITALS

         M-Wave and American Standard are each value-added service providers
that develop, manufacture, and market high performance circuit boards
(collectively, the "Products").

         M-Wave has a manufacturing facility located at 475 Industrial Drive,
West Chicago, Illinois (the "Manufacturing Facility") at which M-Wave has
heretofore manufactured Products and which M-Wave is selling, together with
certain related manufacturing equipment, to affiliates of American Standard,
concurrently with the execution and delivery of this Agreement.

         American Standard and M-Wave desire to enter into a strategic alliance
pursuant to which American Standard shall manufacture Products in place of
M-Wave at the Manufacturing Facility and M-Wave shall assist American Standard
in the sales and marketing of Products, subject to the terms and conditions of
this Agreement.

         The Parties have been party to an Interim Agreement for a Strategic
Operating Alliance, dated as of September 2, 2003 amended on November 14, 2003
(the "Prior Agreement") that is null and void upon execution and delivery of
this Agreement, except for accounts receivable due either party thereunder which
are accrued and unpaid as of the date of execution hereof.

         In consideration of the mutual promises contained herein, and for other
good and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the Parties, intending to be legally bound, hereby agrees as
follows:

                                    AGREEMENT

         1.       RECITALS. The foregoing recitals are a part of this Agreement
and are hereby adopted by this reference and incorporated herein.

         2.       No CONDITIONS PRECEDENT. This Agreement shall be effective
upon its execution and delivery by the Parties and supercedes all previous
writings relating to the subject matter hereof, including without limitation the
Prior Agreement.

                                        1

         3.       MANUFACTURING. American Standard shall manufacture Products
for M-Wave customers at the Manufacturing Facility in accordance with the terms
of this Agreement. Nothing set forth in this Agreement shall preclude M-Wave,
within in its sole discretion, from fulfilling customer orders for Products
outside the Manufacturing Facility from one or more Asian third party vendors
(such Products are herein referred to as "VM Products").

         4.       SALES.

         (a)      Selling. During the Term, M-Wave may sell (1) VM Products to
American Standard's current customers, all of which are listed on Schedule
4(a)(i) attached hereto, and any customers subsequently obtained by American
Standard (collectively, "American Standard's Customers") and (ii) Products and
VM Products to its current customers, all of which are listed on Schedule
4(a)(ii) attached hereto, and any customers subsequently obtained by M-Wave
(collectively, "M-Wave's Customers"). American Standard will receive a six
percent (6%) commission on the sale of VM Products procured by M-Wave for resale
to American Standard's customers. It is the intent of the parties, albeit not
binding on either of them and subject to the making by them in writing of mutual
agreements, that within the Term (as defined hereinbelow) M-Wave will commence,
and thereafter during the Term continue, to sell, as a representative of
American Standard, all Products to the American Standard Customers, and not
merely VM Products.

         (b)      Administration. During the Term, M-Wave will administer,
invoice, collect and service all VM Products it has sold to the American
Standard Customers and all Products and VM Products it has sold to the M-Wave
Customers.

         5.       PURCHASE ORDERS. M-Wave will obtain written purchase orders,
which shall specify all Work to be completed, for review by American Standard.
For the purposes of this Agreement, "Work" shall mean to procure labor,
components, raw materials, equipment and other supplies, and to manufacture,
bond, test, label and deliver the Products to M-Wave. Each purchase order shall
specify the quantity of all Products ordered, the part number, the requested
delivery date and delivery address, price, and reference the applicable written
Specifications. As used herein, "Specifications" shall include, without
limitation, manufacturing plans, test data, quality control data, compositions,
bills of material, samples, schematics, process documentation, labels and test
specifications. Purchase orders shall normally be deemed approved by American
Standard upon receipt, provided, however that American Standard may in good
faith reject any order that (a) American Standard does not have the
technological capacity to manufacture or that does not substantially conform to
the terms and conditions of this Agreement, (b) following a credit check by
American Standard, comes from a customer who does not meet American Standard's
reasonable credit requirements, or (c) does not provide a price that is
reasonably acceptable to American Standard. American Standard shall notify
M-Wave of its disapproval of any purchase order within three (3) business days
of receipt of such order. M-Wave and American Standard will use reasonable
efforts to satisfy any order changes made by a customer and will respond to the
customer regarding meeting the requested change within seven (7) business days
of receipt of a written order requesting such change. The Parties agree that the

                                        2

<PAGE>

terms and conditions contained in this Agreement shall prevail over any terms
and conditions of any purchase order, acknowledgment form or other instrument.

         6.       PRICE AND PAYMENT TERMS.

         (a)      Unit Price. For each Product manufactured for M-Wave
Customers, M-Wave shall pay to American Standard the "Unit Price," which shall
be the standard cost of such Product as set forth in the pricing matrix
spreadsheet used by M-Wave based upon "version 14 of the Calculator" heretofore
agreed upon by the Parties, as may be changed hereafter from time to time by
mutual agreement of the Parties. The standard cost on such pricing matrix
spreadsheet generally equals the difference between (i) the price of such
Product to the customer and (ii) an agreed-upon discount ("Discount"). M-Wave
shall retain the excess of the amount paid by its customer for the Product over
the Unit Price paid by M-Wave to American Standard and disclose this amount to
American Standard.

         (b)      Terms and Lien. Except as otherwise set forth in Section 6(c)
below, payment for each Product by M-Wave to American Standard hereunder is due
within the first to occur of (i) twenty (20) days following the earlier of
shipment to M-Wave or M-Wave's invoicing of the respective receivable or (ii)
five (5) business days following M-Wave's receipt of payment of the applicable
receivable. M-Wave will make best efforts to ship its finished Products within
one (1) business day of manufacture. To secure payment of certain of its
obligations under this Paragraph 6(b), M-Wave hereby grants American Standard a
security interest in its accounts receivable with respect to the payment of such
obligations to American Standard..

         (c)      Revised Terms. M-Wave and American Standard agree that, upon
M-Wave obtaining a credit facility to finance its accounts receivable and
inventory separate from its other assets, American Standard shall immediately
provide M-Wave with thirty (30) day payment terms and a maximum credit limit of
$300,000 and, upon receipt of payment from M-Wave of all amounts due under this
Paragraph 6 in excess of $300,000, shall release the security interest in
M-Wave's accounts receivables granted to American Standard pursuant to Paragraph
6(b) above.

         (d)      Other. The Unit Price is exclusive of federal, state and local
excise, sales, use and similar taxes, and any duties; and M-Wave shall be
responsible for the collection of all such amounts from customers and the
remission of such amounts to the appropriate authorities. The Unit Price is also
exclusive of freight, insurance and other shipping expenses.

         7.       MANUFACTURING EXPENSES. During the Term, the Parties shall
mutually agree in writing as to the allocation between them of the expenses
incurred in connection with the manufacturing activities at the Manufacturing
Facility, including employee costs, insurance, permits and licenses, leasing,
maintenance and repair of equipment, utilities and replacement of equipment.

         8.       PACKAGING AND LABELING. M-Wave, at its own expense, will
package and include Labels on or with all M-Wave Products and packaging to be
supplied in accordance with the applicable Specifications. As used herein,
"Label(s)" shall mean all (a) labels and other written,

                                        3

<PAGE>

printed or graphic matter placed upon the Products, (b) containers and/or
wrappers utilized with the Products including, without limitation, Product
inserts which bear the trademarks or trade dress of M-Wave, and (c) other matter
designated in the Specifications or on approved prototypes/samples.

         9.       SHIPMENTS. M-Wave, at its own expense, shall ship all Products
to the customer in accordance with the applicable Specifications.

         10.      ACCEPTANCE AND REJECTION. If a customer (a) rejects in whole
or in part any shipment of Products because such Products were determined not to
be in accordance with the applicable Specifications (the "Nonconforming
Products") or (b) informs M-Wave of any shortage in quantity of any shipment of
Products, M-Wave shall promptly provide American Standard written notice of such
rejection or shortage and American Standard shall use reasonable efforts to
replace the Nonconforming Products or make up the shortage, at no additional
cost to the customer and as quickly as possible, but in any event within ten
(10) business days of receiving notice of such rejection or shortage. Shipments
of Nonconforming Products may, at M-Wave's option and American Standard's
expense, be returned to M-Wave or destroyed by the customer. The remedy of
replacement or refund will not be available for Nonconforming Products if such
nonconformance was caused by the customer's misuse, unauthorized modifications,
neglect, improper testing or improper storage of such Nonconforming Products.

         11.      CUSTOMER COMPLAINTS. If M-Wave receives a consumer complaint
relating to a defect in any Product or the packaging or Label of any Product,
M-Wave may, in a prompt and reasonable manner, seek the resolution of such
complaint by American Standard in accordance with the terms of this Agreement.

         12.      HAZARDOUS OR UNSAFE CONDITION OF PRODUCTS. In the event
American Standard or M-Wave learns of any condition relating to a potential
safety hazard or unsafe condition in any of the Products, or is advised of such
by any state or federal regulatory authorities having jurisdiction over such
Products, such Party shall immediately advise the other Party and provide all
relevant information, and the Parties shall exert all reasonable efforts to
promptly resolve the situation.

         13.      TERM AND TERMINATION.

degree of care to avoid disclosure of such Confidential Information as it uses

any purposes other than those expressly permitted under this Agreement and shall
not be disclosed to any third party without the prior written consent of the
Disclosing Party.

obligation of confidentiality, at the time of disclosure by the Disclosing
Party; (ii) was generally available to the public or otherwise part of the
public domain at the time of its disclosure to the Receiving Party; (iii) became
generally available to the public or otherwise part of the public domain after
its disclosure and other than through any act or omission of the Receiving Party

disclosure of the other Party's Confidential Information it will give reasonable
advance notice to the other Party of such disclosure requirement, and will use
its best efforts to secure confidential treatment of such Confidential
Information required to be disclosed.

         (d)      All Confidential Information disclosed by a Disclosing Party
to a Receiving Party shall be and shall remain the property of the Disclosing
Party, regardless of such disclosure and regardless of the use of such
Confidential Information by the Receiving Party.

         (e)      It is further understood and agreed that money damages would
not be sufficient remedy for any breach of this Section 19 and that the
Disclosing Party shall be entitled to injunctive relief, including specific
performance, as a remedy for any such breach by the Receiving Party. Such remedy
shall not be deemed to be the exclusive remedy for breach of this Section 23 but
shall be in addition to all other remedies available at law or equity.

         20.      NON-SOLICITATION OF CUSTOMERS AND EMPLOYEES.

         (c)      Blue Pencil Doctrine. If, at the time of enforcement of this
Section 20, a court shall hold that the duration, scope or area restrictions
stated herein are. unreasonable under circumstances then existing, the parties
agree that the maximum duration, scope or area reasonable under such
circumstances shall be substituted for the stated duration, scope or area and
that the court shall be allowed to revise the restrictions contained herein to
cover the maximum period, scope and area permitted by law. Each Party agrees
that the restrictions contained in this Section 20 are reasonable.

         (d)      Breach. In the event of the breach or a threatened breach by a
Party of any of the provisions of this Section 20, the other Party, in addition
and supplementary to other rights and remedies existing in its favor, may apply
to any court of law or equity of competent jurisdiction for specific performance
and/or injunctive or other relief in order to enforce or prevent any violations
of the provisions hereof (without posting a bond or other security).

         21.      PRESS RELEASES. Except as and to the extent required by law,
rule or regulation or, with respect to M-Wave, by rules of the NASDAQ Stock
Market, neither Party shall permit its representatives to make any public
communication or press release regarding the proposed transaction without the
prior written consent of the other Party. If M-Wave determines that a public
press release is appropriate, the Parties shall first agree on the text of such
release, such approval not to be unreasonably withheld. Notwithstanding the
foregoing, M-Wave may make any and all communications, releases and disclosures
that it reasonably determines to be required or desirable under any securities
laws, rules or regulations or rules and regulations of the NASDAQ Stock Market.
Either Party shall provide the other Party with a complete copy of any press

directors, shareholders, representatives, agents and employees (the "M-Wave

fees and expenses, including reasonable legal costs and attorneys' fees
("Losses") resulting from (i) American Standard's breach of any representation,
warranty, covenant or agreement contained in this Agreement; (ii) any
third-party claim, suit or action based upon, attributable to or caused by the
acts or omissions of American Standard; or (iii) the negligent or intentional
wrongful act or omission of American Standard.

<PAGE>

         (b)      Indemnification by M-Wave. M-Wave agrees to indemnify, defend
and hold harmless American Standard and its officers, directors, shareholders,
representatives, agents and employees (the "American Standard Indemnities"),
from and against any and all Losses (as defined above) resulting from (i)
M-Wave's breach of any representation, warranty, covenant or agreement contained
in this Agreement; (ii) any third-party claim, suit or action based upon,
attributable to or caused by the acts or omissions of M-Wave; or (iii) the
negligent or intentional wrongful act or omission of M-Wave.

         (c)      Indemnity Procedure. In the event that a Party (the
"Indemnified Party") is seeking indemnification under this Section 22, it shall
provide prompt written notice to the other Party (the "Indemnifying Party") as
soon as reasonably practicable after it receives notice of the claim, provided
that the failure to so notify the Indemnifying Party shall not relieve the
Indemnifying Party of its obligations hereunder except to the extent such
failure shall have materially prejudiced the Indemnifying Party. The Indemnified
Party shall permit the Indemnifying Party to assume direction and control of the
defense of the claim (including the right to settle the claim solely for
monetary consideration), and, at the Indemnifying Party's expense, shall
cooperate as reasonably requested in the defense of the claim; provided that the
Indemnifying Party may not assume direction and control of the defense of the
claim if (i) the claim seeks non-monetary relief against the Indemnified Party,
(ii) the claim involves criminal allegations against the Indemnified Party, or
(iii) the Indemnified Party reasonably determines that the Indemnifying Party
has failed or is failing to vigorously defend against such claim. The
Indemnified Party shall have the right to retain its own counsel, and the fees
and expenses of the Indemnified Party's counsel will be paid by the Indemnifying
Party if representation of the Indemnified Party by the counsel retained by
Indemnifying Party would be inappropriate due to an actual or potential conflict
of interest. The Indemnifying Party may not settle such action or claim, or
otherwise consent to an adverse judgment in such action or claim, without the
express written consent of the Indemnified Party if such settlement or adverse
judgment diminishes the rights or interests of the Indemnified Party.

         23.      M-WAVE WARRANTS. On the date hereof, M-Wave shall issue a
non-transferable stock purchase warrant to Gordhan Patel (owner of all the

exercise thereof, for his own account and without intention to distribute the
same; and (c) is aware that M-Wave makes filings with the Securities and

         (d)      Waiver. Except as specifically provided for herein, the waiver

this Agreement.

         (e)      Severability. If any term, covenant or condition of this
Agreement or the application thereof to any Party or circumstance shall, to any

         (t)      Entire Agreement. This Agreement sets forth all the covenants,
promises, agreements, warranties, representations, conditions and understandings
between the Parties hereto with regard to the subject matter discussed herein

any representations or warranties on behalf of the other Party, whether express
or implied, or to bind the other Party in any respect whatsoever.

proceeding arising under or out of this Agreement ("Proceeding"), each Party
agrees to submit to the exclusive jurisdiction of the state and federal courts
located in the State of Illinois and hereby waives any objection it may now or
hereafter have to venue or to convenience of forum, agrees that all claims in
respect of the Proceeding shall be heard and determined only in any such court

Parties irrevocably to waive any objections to venue or to convenience of forum.

         (i)      Injunctive Relief. Notwithstanding the foregoing, the Parties
acknowledge and agree that money damages may not be an adequate remedy for any
breach or threatened breach of this Agreement, and that, in such event, any
Party may, in addition to any other rights and remedies existing in its favor,
bring an action in any court of competent jurisdiction situated in Cook, County,
Illinois for specific performance or injunctive relief or for other provisional
relief to compel another Party hereto to comply with its obligations under this
Agreement whether or not any arbitration proceedings have been initiated.

         (j)      Counterparts. This Agreement may be executed in any number of

together will constitute one and the same agreement.
