Exhibit 10.42

FAIR ISAAC CORPORATION
Terms and Conditions of Nonstatutory Stock Option Agreement

          These are the terms and conditions applicable to the NONSTATUTORY STOCK OPTION granted by Fair Isaac Corporation, a Delaware corporation (“Fair Isaac”), to you, the optionee listed on the Notice of Grant of Stock Option attached hereto as the cover page (the “Cover Page”), effective as of the date specified on the Cover Page. The Cover Page together with these Terms and Conditions of Nonstatutory Stock Option Agreement constitute the Nonstatutory Stock Option Agreement (the “Option Agreement”). This Option is granted pursuant to the terms of Fair Isaac’s 1992 Long-term Incentive Plan (the “Plan”).

Nonstatutory		This Option is not intended to qualify as an incentive stock option under Section 422 of the Internal Revenue Code.
Vesting		Your Option vests and will be exercisable on the vesting dates, as shown on the Cover Page. In addition, your entire Option vests and will be exercisable in full in the event that:
		your service as an employee or director of Fair Isaac (or any subsidiary) terminates because of your Disability or death, or
		any written employment agreement (other than a stock option agreement) between you and Fair Isaac provides for acceleration of this Option upon a change in control of Fair Isaac or upon any other specified event or combination of events.
		No additional shares become exercisable after your employment or service with Fair Isaac has terminated for any reason; and all unvested options hereunder are cancelled as of the last day of your employment or service. Vested options may be exercised in the manner and during the period of time set forth in this Option Agreement.
Exercise Period		The right to purchase shares under this Option Agreement terminates at 3:00 p.m. Pacific Time on the earliest of
		the Expiration Date shown on the Cover Page; or
		the 90th day after the termination date of your service as an employee or director of Fair Isaac (or any subsidiary), except if your termination results from Retirement, Disability or death; or
		the anniversary date of your Retirement as an employee or director of Fair Isaac (or any subsidiary); or
		the anniversary date of the commencement of your Disability, if you become disabled while an employee or director of Fair Isaac (or any subsidiary) or
		the anniversary date of your death, if you die while an employee or director of Fair Isaac (or any subsidiary).

Leaves of Absence		For purposes of this Option, your service does not terminate when you go on a military leave, a sick leave or another bona fide leave of absence, if the leave was approved by Fair Isaac in writing.
		Unless you return to active work upon termination of your approved leave, your service will be treated as terminating on the later of 90 days after you went on leave or the date that your right to return to active work is guaranteed by law or by a contract. Fair Isaac will determine which leaves count for this purpose.
Restrictions on Exercise		You may not exercise this Option if the issuance of shares at that time would violate any law or regulation, as determined by Fair Isaac. Moreover, you cannot exercise this Option unless you have accepted this Option in accordance with procedures specified by Fair Isaac.
Notice of Exercise		If you do not exercise this Option through an automated electronic exercise system approved by Fair Isaac, then you must notify Fair Isaac in writing of your intent to exercise this Option.
		The notice must specify how many shares you wish to purchase and must specify how your shares should be registered (i.e., in your name only, in your and your spouse’s names as community property, or as joint tenants with right of survivorship).
