Each advance is M-Wave's representation and warranty on that date that the representations and warranties set forth in the Loan Agreements remain true.

3.5 Mandatory Repayments and Reduction of Additional Credit. Except for sales of inventory in the ordinary course of business, the net sale proceeds (which, in the case of the sale of any assets of DBS, includes trade payables attributable to DBS) of the sale of any assets of either Borrower shall be paid to Lender for application to the outstanding principal amount of the Loans or the Additional Credit (and shall be applied to the Additional Credit and the Loans in any order Lender may choose).

3.6 Cross-Default. Any Event of Default under the 2004 Loan Agreement or the 2005 Loan Agreement shall constitute a default under each other loan or other obligation (other than the 2004 Loan, the 2005 Loan or the Additional Credit) at any time owing from either of the Borrowers to either Lender or Monarch, and any default or event of default (subject to any applicable notice and cure rights) under and as defined in any agreement (other than the 2004 Loan Agreement or the 2005 Loan Agreement) between either of the Borrowers, on the one hand, and either Lender or Monarch, on the other, shall constitute an Event of Default under each of the 2004 Loan Agreement and the 2005 Loan Agreement.

4.   Waiver of Existing Defaults. In consideration of the waiver fee described below, upon this Amendment's becoming effective Lender waives all outstanding Events of Default on the Loans that arise from acts, omissions or circumstances (or, with notice or the passage of time or both, would arise from acts, omissions or circumstances) that occurred or arose prior to the date of this Amendment. The Borrowers shall pay to Lender a waiver fee of Ten Thousand Dollars ($10,000.00), $5,000.00 of which is allocated to each of the 2004 Loan and the 2005 Loan and added to the outstanding principal amount thereof as of the date of this Agreement. Interest shall accrue on the unpaid amount of such fee from and after the effective date of this Amendment, and such fee shall be due and payable to Lender on June 28, 2006. Except as expressly waived by this Section 4, Lender reserves all of its rights and remedies under the Loan Documents.

- 5 -

5.   Conditions Precedent. This Amendment shall become effective upon Lender's receipt of fully executed and, where appropriate, acknowledged originals of this Amendment and any other documents that Lender may require or request in accordance with this Amendment or the other Loan Documents.

6.   The Borrowers' Representations and Warranties. Each of the Borrowers represents and warrants to Lender as follows:

(a) Loan Documents. All representations and warranties made and given by such Borrower in the Loan Documents are true, accurate and correct.

(b) No Default. Subject to the effectiveness of the waiver set forth in Section 4, above, no Event of Default has occurred and is continuing, and no event has occurred and is continuing which, with notice or the passage of time or both, would be an Event of Default.

(c) Borrowing Entity. M-Wave is a corporation that is duly organized and validly existing under the laws of the State of Delaware, and is qualified to do business in each jurisdiction in which its ownership of assets or the conduct of its business requires such qualification. There have been no changes in the organization, ownership structure or formation documents of M-Wave that have not been disclosed to Lender. DBS is a corporation that is duly organized and validly existing under the laws of the State of Illinois, and is qualified to do business in each jurisdiction in which its ownership of assets or the conduct of its business requires such qualification. There have been no changes in the organization, ownership structure or formation documents of DBS that have not been disclosed to Lender. DBS is the sole subsidiary of M-Wave.

7.   Incorporation. Upon its effective date, this Amendment shall constitute a Loan Document and shall form a part of each Loan Document, and all references to a given Loan Document shall mean that document as hereby modified.

8.   No Prejudice; Reservation of Rights. This Amendment shall not prejudice any rights or remedies of Lender under the Loan Documents. Lender reserves, without limitation, all rights that it has against any indemnitor, guarantor or other person or entity from time to time liable under any of the Loan Documents.

9.   No Impairment. Except as specifically hereby amended, the Loan Documents shall each remain unaffected by this Amendment, and all such documents shall remain in full force and effect.

10. Expenses. The Borrowers shall reimburse Lender on demand, in immediately available funds, for all costs and expenses incurred by Lender in connection with this Amendment, including legal fees and expenses of Lender's counsel.

- 6 -

11. Purpose and Effect of Approvals. Approval of any matter in connection with the Loans by Lender shall be for the sole purpose of protecting the security and rights of Lender. No such approval shall result in a waiver of any default by a Borrower. In no event shall any approval of Lender constitute a representation of any kind with regard to the matter being approved.

12. Integration. The Loan Documents, including this Amendment: (a) integrate all the terms and conditions mentioned in or incidental to the Loan Documents; (b) supersede all oral negotiations and prior and other writings with respect to their subject matter; and (c) are intended by the parties as the final expression of their agreement with respect to the terms and conditions set forth in those documents and as the complete and exclusive statement of the terms agreed to by the parties. If there is any conflict between the terms, conditions and provisions of this Amendment and those of any other agreement or instrument, including any of the other Loan Documents, the terms, conditions and provisions of this Amendment shall prevail.

13. Miscellaneous. The obligations of the Borrowers under this Amendment and each of the other Loan Documents are joint and several. This Amendment may be executed in counterparts, and all counterparts shall constitute but one and the same document. If any court of competent jurisdiction determines any provision of this Amendment or any of the other Loan Documents to be invalid, illegal or unenforceable, that portion shall be deemed severed from the rest, which shall remain in full force and effect as though the invalid, illegal or unenforceable portion had never been a part of the Loan Documents. This Amendment shall be governed by the laws of the State of California, without regard to the choice of law rules of that State. As used here, the word "include(s)" means "includes(s), without limitation," and the word "including" means "including, but not limited to."
