EXHIBIT 10.1 [AMENDED AND RESTATED] CHANGE-OF-CONTROL EMPLOYMENT AGREEMENT AGREEMENT, effective as of the 1st day of January, 2009, by and between Smith International, Inc., a Delaware Corporation (the "Company") and [          ] (the "Executive"). [WHEREAS, the Executive and the Company are parties to that certain change-of-control employment agreement dated [      ] (the " Original Agreement "); and WHEREAS, the Executive and the Company desire to amend and restate the Original Agreement ; and] WHEREAS, the Board of Directors of the Company (the " Board "), has determined that it is in the best interests of the Company and its shareholders to assure that the Company will have the continued dedication of the Executive, notwithstanding the possibility, threat or occurrence of a Change of Control (as defined below) of the Company. The Board believes it is imperative to diminish the inevitable distraction of the Executive by virtue of the personal uncertainties and risks created by a pending or threatened Change of Control and to encourage the Executive’s full attention and dedication to the Company currently and in the event of any threatened or pending Change of Control, and to provide the Executive with compensation and benefits arrangements upon a Change of Control which ensure that the compensation and benefits expectations of the Executive will be satisfied and which are competitive with those of other corporations. Therefore, in order to accomplish these objectives, the Board has caused the Company to enter into this Agreement. NOW, THEREFORE, IT IS HEREBY AGREED AS FOLLOWS:                      Certain Definitions . (a) The " Effective Date ", shall mean the first date during the Change of Control Period (as defined in Section l (b)) on which a Change of Control (as defined in Section 2) occurs. Anything in this Agreement to the contrary notwithstanding, if a Change of Control occurs and if the Executive’s employment with the Company is terminated by the Company within the 12 months prior to the date on which the Change of Control occurs, which Change of Control is a "change in control event" within the meaning of Section 409A of the Code, and if it is reasonably demonstrated by the Executive that such termination of employment (i) was at the request of a third party who has taken steps reasonably calculated to effect such Change of Control or (ii) otherwise arose in connection with or anticipation of such Change of Control (such a termination of employment, an " Anticipatory Termination "), then for all purposes of this Agreement the " Effective Date " shall mean the date immediately prior to the date of such termination of employment. Notwithstanding the foregoing, the Executive and the Company acknowledge that, except as may otherwise be provided under this Agreement or any other written agreement between the Executive and the Company, the employment of the Executive by the Company is "at will."                     The " Change of Control Period " shall mean the period commencing on the date hereof and ending on the third anniversary of the date hereof; provided, however, that commencing on the date one year after the date hereof, and on each annual anniversary of such date (such date and each annual anniversary thereof shall be hereinafter referred to as the " Renewal Date "), unless previously terminated, the Change of Control Period shall be automatically extended so as to terminate three years from such Renewal Date, unless at least 60 days prior to the Renewal Date the Company shall give notice to the Executive that the Change of Control Period shall not be so extended.                      Change of Control .

In such event, the Executive’s employment with the Company shall terminate effective on the 30th day after receipt of such notice by the Executive (the " Disability Effective Date "), provided that, within the 30 days after such receipt, the Executive shall not have returned to full-time performance of the Executive’s duties.

The Company may terminate the Executive’s employment during the Employment Period for Cause. For purposes of this Agreement, " Cause " shall mean:

                    the willful and continued failure of the Executive to perform substantially the Executive’s duties with the Company or one of its affiliates (other than any such failure resulting from incapacity due to physical or mental illness), after a written demand for substantial performance is delivered to the Executive by the Board or the Chief Executive Officer of the Company which specifically identifies the manner in which the Board or Chief Executive Officer believes that the Executive has not substantially performed the Executive’s duties, or                     the willful engaging by the Executive in illegal conduct or gross misconduct which is materially and demonstrably injurious to the Company. For purposes of this provision, no act or failure to act, on the part of the Executive, shall be considered "willful" unless it is done, or omitted to be done, by the Executive in bad faith or without reasonable belief that the Executive’s action or omission was in the best interests of the Company. Any act, or failure to act, based upon (A) authority given pursuant to a resolution duly adopted by the Board or, if the Company is not the ultimate parent of a group of affiliated companies and is not publicly-traded, the board of directors or equivalent governing body of the ultimate parent of the Company (the " Applicable Board "), [(B) the instructions of the Chief Executive Officer or a senior officer of the Company]1 or (C) the advice of counsel for the Company shall be conclusively presumed to be done, or omitted to be done, by the Executive in good faith and in the best interests of the Company. The cessation of employment of the Executive shall not be deemed to be for Cause unless and until there shall have been delivered to the Executive a copy of a resolution duly adopted by the affirmative vote of not less than three-quarters of the Applicable Board (excluding the Executive, if the Executive is a member of the Applicable Board) at a meeting of the Applicable Board called and held for such purpose (after reasonable notice is provided to the Executive and the Executive is given an opportunity, together with counsel, to be heard before the Applicable Board), finding that, in the good faith opinion of the Applicable Board, the Executive is guilty of the conduct described in subparagraph (i) or (ii) above, and specifying the particulars thereof in detail.                      Good Reason . The Executive’s employment may be terminated by the Executive for Good Reason. For purposes of this Agreement, " Good Reason " shall mean:                     the assignment to the Executive of any duties inconsistent in any respect with the Executive’s position (including status, offices, titles and reporting requirements), authority, duties or responsibilities as contemplated by Section 4(a) of this Agreement, or any other action by the Company which results in a diminution in such position, authority, duties or responsibilities (including as a result of the Company’s ceasing to be a publicly traded entity), excluding for this purpose an isolated, insubstantial and inadvertent action not taken in bad faith and which is remedied by the Company promptly after receipt of notice thereof given by the Executive;                     any failure by the Company to comply with any of the provisions of Section 4(b) of this Agreement, other than an isolated, insubstantial and inadvertent failure not occurring in bad faith and which is remedied by the Company promptly after receipt of notice thereof given by the Executive;                     the Company’s requiring the Executive to be based at any office or location other than as provided in Section 4(a)(i)(B) hereof or to travel on Company business to a substantially greater extent than required immediately prior to the Effective Date;                     any purported termination by the Company of the Executive’s employment otherwise than as expressly permitted by this Agreement; or                     any failure by the Company to comply with and satisfy Section 11(c) of this Agreement. For purposes of this Section 5(c), any good faith determination of " Good Reason " made by the Executive shall be conclusive. Anything in this Agreement to the contrary notwithstanding, a termination by the Executive for any reason during the 30-day period immediately following the first anniversary of the Effective Date shall be deemed to be a termination for Good Reason for all purposes of this Agreement. The Executive’s mental or physical incapacity following the occurrence of any of the circumstances described in clauses (i) through (v) shall not affect the Executive’s ability to terminate employment for Good Reason and the Executive’s death following delivery of a Notice of Termination for Good Reason shall not affect the Executive’s estate’s entitlement to severance payments and benefits provided hereunder upon a termination of employment for Good Reason. Notwithstanding anything herein to the contrary, the Executive’s resignation under this Agreement with or without Good Reason shall in no way affect the Executive’s ability to terminate employment by reason of the Executive’s retirement or to be eligible to receive benefits under any retirement or pension plan of the Company and its affiliates.                      Notice of Termination . Any termination by the Company for Cause, or by the Executive for Good Reason, shall be communicated by Notice of Termination to the other party hereto given in accordance with Section 12(b) of this Agreement. For purposes of this Agreement, a " Notice of Termination " means a written notice which indicates the specific termination provision in this Agreement relied upon, (ii) to the exten
