EXPLANATORY NOTE

Mercury Computer Systems, Inc. (the “Company”) is filing this post-effective amendment to deregister certain of the securities originally registered pursuant to the Registration Statement on Form S-8 (File No. 333-112990), filed with the Securities and Exchange Commission on February 20, 2004 (the “Registration Statement”) with respect to shares of the Company’s common stock, par value $0.01 per share (“Common Stock”), thereby registered for issuance under the Company’s 1997 Stock Option Plan, as amended (the “1997 Plan”). An aggregate of 1,000,000 shares of Common Stock were registered for issuance under the 1997 Plan pursuant to the Registration Statement.

On November 14, 2005, the Company’s shareholders approved the Company’s 2005 Stock Incentive Plan (the “2005 Plan”), which replaced the 1997 Plan as of the date of approval. Following the approval of the 2005 Plan, no future awards may be made under the 1997 Plan. The maximum number of shares of Common Stock reserved and available for issuance under the 2005 Plan includes the shares available for grant under the 1997 Plan as of the effective date of the 2005 Plan, plus the number of shares underlying any grants previously made under the 1997 Plan that are forfeited, canceled or terminated (other than by exercise) from and after the effective date of the 2005 Plan. The total number of shares available for grant under the 1997 Plan as of the effective date of the 2005 Plan was 1,942,264 shares (the “Original Carried Forward Shares”). The Original Carried Forward Shares included 942,264 shares registered under the Registration Statement, which were deregistered pursuant to Post-Effective Amendment No. 1 to the Registration Statement filed on November 23, 2005. An aggregate of 2,449,981 additional shares (the “Additional Carried Forward Shares”) have been included in the shares reserved for issuance under the 2005 Plan as a result of the forfeiture, cancellation or termination (other than by exercise) of previously-made grants under the 1997 Plan during the period between the effective date of the 2005 Plan and October 31, 2006. The Additional Carried Forward Shares include the remaining 57,736 shares registered under the Registration Statement, which are hereby deregistered.

Contemporaneously with the filing of this Post-Effective Amendment No. 2 to the Registration Statement, the Company is filing a Registration Statement on Form S-8 to register the Additional Carried Forward Shares for issuance pursuant to the 2005 Plan.
