If Shareholder desires to have any of the Shares registered in the Registration Statement, then Shareholder shall notify Cerprobe in writing of Shareholder's desire and deliver such written notice to Cerprobe within ten (10) days of receiving the Filing Notice from Cerprobe. If Shareholder timely notifies Cerprobe of Shareholder's desire to register the Shares for sale, then Cerprobe, with the consent and the approval of the underwriters selected by Cerprobe to assist Cerprobe in the offering covered by the Registration Statement (such consent and approval to be in the sole discretion of such underwriters), shall include in that Registration Statement, on the same terms and conditions (except as otherwise provided in this Agreement) as the other Common Stock to be offered for sale pursuant to the Registration Statement (except as otherwise provided in this Agreement), the following number of the Shares, or such smaller number of the Shares as Shareholder shall elect to have registered: B A x --- C Where A equals the total number of Shares acquired by Shareholder pursuant to the Agreement of Merger that are held of record by Shareholder on the date of the Filing Notice; and Where B equals the number of shares of Common Stock being registered for the person, firm or entity (other than Cerprobe) for whom the largest percentage of shares of Common Stock held by him, her or it is being registered; and Where C equals the total number of shares of Common Stock held by such person, firm or entity. (b) Notwithstanding any other provisions of this Section 1, if the underwriters selected by Cerprobe advise Cerprobe that, in the sole discretion of such underwriters, marketing factors require a limitation on the number of shares to be underwritten, then Cerprobe may exclude all or any portion of the shares of Common Stock or Shareholder's Shares to be registered by the holders thereof (other than by Cerprobe) or limit the number of such shares or Shareholder's Shares to be included. Any such reduction shall, to the extent reasonably practicable, be allocated among such holders, including Shareholder, pro rata on the basis of the number of shares requested for inclusion in the Registration Statement. (c) All brokerage fees, discounts and commissions in respect of the registration of the Shares or any portion thereof under this Agreement and applicable transfer taxes payable upon the sale of the Shares so registered, in connection with the registration of the Shares or any portion thereof under this Agreement shall be paid and borne by Cerprobe to the extent paid and borne by Cerprobe for any other shareholder (other than Cerprobe) selling Common Stock under the Registration Statement, otherwise such fees, discounts and commissions shall be paid and 2 borne by Shareholder.

Lock-up Agreements. If any portion of Shareholder's Shares is registered in the Registration Statement (the "Registration"), then Shareholder shall not, unless the underwriters selected by Cerprobe otherwise agree in writing, effect any public sale or distribution of any other equity securities of Cerprobe, or any securities convertible into or exchangeable or exercisable for those securities, during the period commencing on the filing date of the Registration Statement with the SEC, and ending one hundred eighty (180) days after the effective date of any such Registration, or such longer period as the other selling shareholders (other than Cerprobe) may agree. 3. Registration Procedures. Whenever Shareholder has requested that the Shares, or any portion thereof, subject to this Agreement be registered pursuant to this Agreement, Cerprobe will use its reasonable efforts to effect the registration and the sale of such Shares in accordance with the intended method of disposition thereof, and pursuant thereto Cerprobe will: (a) prepare and file with the SEC a Registration Statement with respect to such Shares and use its reasonable efforts to cause the Registration Statement to become effective; provided, however, Cerprobe shall have the sole right and discretion to withdraw or terminate any Registration; (b) furnish to Shareholder such reasonable number of copies of the Registration Statement, each amendment and supplement thereto, the prospectus included in such Registration Statement (including each preliminary prospectus) in order to facilitate the disposition of such Shares owned by Shareholder; and (c) provide or continue to provide a transfer agent and registrar for such Shares not later than the effective date of the Registration Statement. 4.
