Item 4. Purpose of Transaction

Item 4 of the Schedule 13D is hereby amended and restated in its entirety to read as follows:

The SUNN Acquisition Stockholders intend to cause SUNN Acquisition to effect a “short-form” merger with and into Suntron under Delaware General Corporation Law Section 253, and then cause Suntron to file a Form 15 (Certification of Termination of Registration of a Class of Security) with the Securities and Exchange Commission.

The short-form merger will enable the SUNN Acquisition Stockholders to acquire all of the Shares they will not already own, and will provide a source of liquidity to holders of those Shares. As a result of the short-form merger, each Share not owned by SUNN Acquisition will be converted into the right to receive $1.15 in cash, without interest.

For more information regarding the purpose of this transaction, see the Schedule 13E-3 of SUNN Acquisition and Thayer-BLUM, filed concurrently with this Amendment No. 1.
