EXPLANATORY STATEMENT

This Post-Effective Amendment No. 1 to Registration Statement on Form S-8 filed on January 23, 2001 (File No. 333-54186) is filed in order to deregister securities remaining under such Registration Statement.

On January 23, 2001, the Registrant filed the Registration Statement on Form S-8 (File No. 333-54186) to register an aggregate of 2,000,000 (4,500,000 after stock-splits) Common Shares issuable under the 2000 Stock Awards Plan (the “2000 Plan”) of Benchmark Electronics, Inc. On August 21, 2006, the Registrant filed the Registration Statement on Form S-8 (File No. 333-136798) to register an aggregate of 6,750,000 Common Shares issuable under the 2000 Plan. On May 18, 2010 (the “Approval Date”), the Registrant’s shareholders approved the adoption of the 2010 Omnibus Incentive Compensation Plan (the “2010 Plan”) which provides, among other things, that any Common Shares with respect to awards granted under the 2000 Plan that are outstanding on the Approval Date (such shares, the “Outstanding Award Shares”) and are forfeited following the Approval Date will become available for issuance under the 2010 Plan. In addition, as of the Approval Date, no future awards will be made under the 2000 Plan and therefore, the Common Shares that were available for grant under the 2000 Plan as of the Approval Date but were not subject to outstanding awards as of such date (such shares, the “Remaining Shares”) will not be issued pursuant to the 2000 Plan. As of the date hereof, there was an aggregate of 5,267,613 Outstanding Award Shares and an aggregate of 3,815,957 Remaining Shares (all such shares are collectively referred to as the “2000 Plan Shares”).

This Post-Effective Amendment No. 1 and Post-Effective Amendment No. 1 to the Registration Statement on Form S-8 (File No. 333-136798) are being filed to deregister the 2000 Plan Shares. The Registrant is concurrently filing a separate Registration Statement on Form S-8 to reflect that the Outstanding Award Shares may be issued under either the 2000 Plan or the 2010 Plan and to carry over the filing fees for the Outstanding Award Shares.

In accordance with the principles set forth in Interpretation 89 under Section G of the Manual of Publicly Available Telephone Interpretations of the Division of Corporation Finance of the Securities and Exchange Commission (July 1997) and Instruction E to the General Instructions to Form S-8, this Post-Effective Amendment No. 1 is hereby filed (i) to reflect that, following the date hereof, the Outstanding Award Shares may be issued under either the 2000 Plan or the 2010 Plan, and (ii) to carry over the registration fees paid for the Outstanding Award Shares from the Registration Statement on Form S-8 (File No. 333-54186), filed for the 2000 Plan, to the Registration Statement on Form S-8, filed for both the 2000 Plan and the 2010 Plan, which is filed contemporaneously with the filing of this Post-Effective Amendment No. 1.
