AGREEMENT

     1. Resignation. Grudnowski hereby confirms his resignation as Chief Executive Officer of the Company, as a director of the Board, and from any other officer or director position with the Company or any of its subsidiaries or affiliates effective as of the Resignation Date. Grudnowski confirms that his resignation as a director of the Company did not arise from any disagreement he has with the Company on any matter relating to the Company’s operations, policies or practices. A press release announcing Grudnowski’s resignation was made by the Company on November 1, 2006, with the text set forth in Exhibit A.

     2. Earned Compensation. The Company shall pay Grudnowski earned Base Salary through the Resignation Date in accordance with Section 4(a) of the Employment Agreement. In addition, the Company shall pay Grudnowski an Incentive Award for fiscal year ended September 30, 2006, in the gross amount of $660,000, pursuant to Section 4(b) of the Employment Agreement, at such time as the Incentive Award would be paid pursuant to the Company’s normal practices as to such awards in the past, but not earlier than the expiration of the rescission period set forth in Section 14 of this Agreement and in the Release. The Company and Grudnowski acknowledge and agree that Grudnowski is not eligible for an annual option grant pursuant to Section 4(c)(ii) of the Employment Agreement or to any other incentive compensation for the period ending on the Resignation Date. The Company shall pay Grudnowski for all earned and unused vacation time as of the Resignation Date, in the amount of $14,942.13, no later than November 30, 2006.

     3. Transition Term.

           (a) Scope of Engagement. Subject to the terms and conditions of this Agreement, Grudnowski agrees to remain in the employ of the Company, and the Company agrees to continue Grudnowski’s employment, for the period from the Resignation Date through January 31, 2007 (the “Transition Term”). During the Transition Term, Grudnowski shall have no direct reports; his responsibility and authority shall be limited to such transition assistance and special project matters as may be requested by the Chair of the Board and/or the Company’s Chief Executive Officer.

           (b) Pay and Benefits. Grudnowski’s Base Salary shall be continued through the Transition Term at the rate in effect immediately prior to November 1, 2006. In addition, during the Transition Term Grudnowski shall participate in such other employee benefit plans and programs for which he may be eligible and in which he participated prior to the Resignation Date, pursuant to the terms and conditions of such plans; provided, however, that Grudnowski shall not accrue any additional vacation time, and shall not be eligible for any incentive, bonus, option or other compensation award except as specifically set forth in this Agreement. Grudnowski’s right to continued Base Salary and benefits shall cease immediately and automatically upon expiration of the Transition Term. In connection with the Termination Date, Grudnowski shall receive notice of post-employment rights and benefits consistent with the departure from the Company of a senior executive of the Company.

           (c) Expenses. The Company shall reimburse Grudnowski for all reasonable and necessary out-of-pocket business, travel and entertainment expenses incurred by him in the performance of his duties and responsibilities for the Company, subject to the Company’s normal policies and procedures for expense verification and documentation. Request for reimbursement of expenses shall be submitted by Grudnowski with supporting documentation to the Company’s Vice President of Human Resources.

     4. Stock Options. Grudnowski acknowledges and agrees that the spreadsheet set forth as Exhibit B is an accurate list of all option grants received by Grudnowski during his employment with the Company, including the currently outstanding vested and unvested Options. The Options shall continue to be governed by the terms and conditions set forth in the applicable written stock option agreements signed by Grudnowski and the Company. For purposes of Grant Nos. 008231, 006151 and 005331, the parties agree that Grudnowski’s employment with the Company is terminating by mutual written agreement between the Company and Grudnowski for reasons other than for Cause; provided, however, that Grudnowski agrees that he is hereby waiving and forfeiting any and all right to the 187,500 unvested shares subject to Grant No. 005331, and the options to purchase such unvested shares shall immediately expire effective on the Effective Date.

     5. Release. At the same time Grudnowski signs this Agreement, he also will sign a Release, in the form attached to this Agreement as Exhibit C (the “Release”), in favor of the Company and its affiliates, divisions, subsidiaries, committees, trustees, directors, officers, employees, agents, predecessors, successors, and assigns. This Agreement will not be interpreted or construed to limit the Release in any manner. The existence of any dispute related to the interpretation of this Agreement or the alleged breach of this Agreement will not nullify or otherwise affect the validity or enforceability of the Release.

     6. Severance Pay. In exchange for Grudnowski’s obligations and commitments under this Agreement, including without limitation in order to ensure a smooth transition, to allow accessibility to Grudnowski’s experience and knowledge of the Company’s business operations and industry, and to prevent future employment of Grudnowski with a competitor of the Company, the Company shall pay to Grudnowski severance pay in the aggregate amount of two times Grudnowski’s Base Salary as of the Resignation Date. The severance pay shall be payable to Grudnowski in a lump sum on or about August 3, 2007.

     7. Non-Disclosure, Non-Competition and Non-Solicitation Agreements.

           (a) Confidential Information. Grudnowski acknowledges entering into the Confidentiality Agreements and hereby reaffirms his commitments and obligations under the Confidentiality Agreements. Nothing in this Agreement is intended to modify, amend, cancel or supersede the Confidentiality Agreements in any manner.

           (b) Restrictive Covenant. Grudnowski agrees that during the Transition Term and for a period of twenty-four (24) consecutive months following the Transition Term, Grudnowski shall not, in North America or any other location where the Company or any of its

subsidiaries is currently doing business, directly or indirectly engage or participate in the ownership, management, operation, or control, or invest in, be employed or perform any services for any person, firm, corporation or other entity operating a business that competes with, is preparing to compete with, or is engaged in any material aspect of the business of the Company or any of the Company’s subsidiaries. Grudnowski may, nevertheless, as a passive investor, own less than 2% of the outstanding shares of capital stock of any corporation listed on a national securities exchange or publicly traded in the over-the-counter market that competes with the Company.

           (c) Covenant Not to Hire or Recruit. Grudnowski recognizes that the Company’s work force constitutes an important and vital aspect of its business. Grudnowski agrees that during the Transition Term and for a period of twenty-four (24) consecutive months following the Transition Term, Grudnowski shall not, directly or indirectly, solicit, request, advise, induce or influence any person who is then employed or engaged by the Company or by any of its subsidiaries (as an agent, employee, independent contractor, or in any other capacity), or who was an employee of the Company or any of its subsidiaries at any time during the Transition Term, to terminate his or her employment, agency or relationship with the Company, any of its subsidiaries or any successor thereto.

           (d) Acknowledgement. Grudnowski agrees that the restrictions and agreements contained in this Section 7 are reasonable and necessary to protect the legitimate interests of the Company and that any violation of this Section 7 will cause substantial and irreparable harm to the Company that would not be quantifiable and for which no adequate remedy would exist at law and accordingly injunctive relief will be available for any violation of this Section 7.

           (e) Blue-Pencil Doctrine. If the duration or geographical extent of, or business activities covered by, this Section 7 are in excess of what is valid and enforceable under applicable law, such provision will be construed to cover only that duration, geographical extent, or activities that are valid and enforceable. Grudnowski acknowledges the uncertainty of the law in this respect and expressly stipulates that this Section 7 be given the construction which renders its provisions valid and enforceable to the maximum extent (not exceeding its express terms) possible under applicable laws.

     8. Return of Property. Grudnowski agrees that all property in Grudnowski’s possession belonging to the Company or any of its subsidiaries, including without limitation, all documents, reports, manuals, memoranda, computer print-outs, customer lists, credit cards, keys, identification, products, access cards, and all other property relating in any way to the business of the Company (“Company Property”) are the exclusive property of the Company, even if Grudnowski authored, created, or assisted in authoring or creating such Company Property. Grudnowski shall return to the Company all Company Property within ten (10) business days following the Resignation Date. Grudnowski agrees to return to the Company any and all Company Property that may be provided to him by the Company during the Transition Term immediately upon the end of the Transition Term, or at such earlier time as the Company may

reasonably request. The Company agrees that it will return to Grudnowski all property in its possession belonging to Grudnowski that is not Company Property.

     9. Indemnification. Notwithstanding Grudnowski’s resignation as an officer and director of the Company or termination of his employment upon the conclusion of the Transition Term, with respect to events that occurred during his tenure as an employee, officer or director of the Company, Grudnowski will be entitled, as a former employee, officer or director of the Company, to the same rights that are afforded to other current or former employees, officers, or directors of the Company, now or in the future, to indemnification and advancement of expenses as provided in the charter documents of the Company and under applicable law, and to indemnification and a legal defense to the extent provided from time to time to current officers and directors by any applicable general liability and/or directors’ and officers’ liability insurance policies maintained by the Company.

     10. Cooperation.

           (a) Agreement to Assist and Cooperate. At the Company’s reasonable request and upon reasonable notice, Grudnowski will, from time to time and without further consideration, during and following the Transition Term, timely execute and deliver such acknowledgements, instruments, certificates, and other ministerial documents (including without limitation, certification as to specific actions performed by Grudnowski in his capacity as an officer or director of the Company) as may be necessary or appropriate to formalize and complete the applicable corporate records. In addition, at the Company’s reasonable request and upon reasonable notice, Grudnowski will, during the Transition Term and without further consideration, discuss and consult with the Company regarding business matters that he was directly and substantially involved with while employed by the Company.

           (b) Claims Involving the Company. Grudnowski agrees that he will, at any future time, be available upon reasonable notice from the Company, with or without subpoena, to be interviewed, review documents or things, give depositions, testify, or engage in other reasonable activities in connection with any litigation or investigation, with respect to matters that Grudnowski has or may have knowledge of by virtue of his employment by or service to the Company or any related entity. In performing his obligations under this Section 10(b) to testify or otherwise provide information, Grudnowski will honestly, truthfully, forthrightly, and completely provide the information requested. Grudnowski will comply with this Agreement upon notice from the Company that the Company or its attorneys believe that his compliance would be helpful in the resolution of an investigation or the prosecution or defense of claims. In the event that Grudnowski’s services under Section 10(a) or 10(b) exceed five (5) hours in any calendar month following the Transition Term, the Company shall compensate Grudnowski for such additional services at the hourly rate of $200.

           (c) Communications. Inquiries and communications initiated by Grudnowski to the Company regarding Company business shall be directed to the Chair of the Board or to the Company’s Chief Executive Officer or to any person they designate.

     11. Non-disparagement. Grudnowski will not malign, defame, or disparage the reputation, character, image, products, or services of the Company, or the reputation or character of the Company’s directors, officers, employees, or agents. The Company (by and through the current members of the Board and the current executive officers of the Company) will not at any time disparage, defame or besmirch the reputation, character or image of Grudnowski. Nothing in this Agreement is intended to prevent or interfere with any party making any required or reasonable communications with, or providing information to, any governmental, law enforcement, or stock exchange agency or representative, or in connection with any governmental investigation, court, administrative or arbitration proceeding.

     12. Taxes. The Company may take such action as it deems appropriate to insure that all applicable federal, state, city and other payroll, withholding, income or other taxes arising from any compensation, benefits or any other payments made pursuant to this Agreement, and in order to comply with all applicable federal, state, city and other tax laws or regulations, are withheld or collected from Grudnowski. This Agreement is intended to satisfy the requirements of Section 409A(a)(2), (3) and (4) of the Internal Revenue Code of 1986, as amended (“Code”), including current and future guidance and regulations interpreting such provisions. Grudnowski acknowledges and agrees that the Company has made no assurances or representations to him regarding the tax treatment of any consideration provided for in this Agreement and that the Company has advised him to obtain his own personal tax advice. Except for any tax amounts withheld by the Company from the payments or other consideration hereunder and any employment taxes required to be paid by the Company, Grudnowski shall be responsible for payment of any and all taxes owed in connection with the consideration provided for in this Agreement.

     13. Time to Consider Agreement. Grudnowski understands that he may take twenty-one (21) calendar days after the date he receives this Agreement and the Release to decide whether to sign this Agreement and the Release. Grudnowski represents that if he signs this Agreement and the Release before the expiration of the twenty-one (21) day period, it is because he has decided that he does not need any additional time to decide whether to sign this Agreement and the Release.

Grudnowski understands that if he rescinds or revokes this Agreement or the Release, the rescission must be in writing and hand-delivered or mailed to the Company in the manner set forth in the Release.

     15. Full Compensation. Grudnowski acknowledges and understands that the payments made and other consideration provided by the Company under this Agreement will fully compensate Grudnowski for and extinguish any and all of the potential claims Grudnowski is releasing in the Release, including without limitation, his claims for attorneys’ fees and costs and any and all claims for any type of legal or equitable relief.

     16. No Admission of Wrongdoing. Grudnowski and the Company each understand and agree that this Agreement and the Release do not constitute an admission by any party that such party has violated any local ordinance, state or federal statute, or principle of common law, that any party has engaged in any unlawful or improper conduct, or that either party has been treated unfairly. Neither party will characterize this Agreement, the Release or the exchange of any consideration in accordance with this Agreement as an admission that any party has engaged in any unlawful or improper conduct.

Fourth quarter fiscal 2006 results included share-based compensation expense of $7.4 million after-tax, or $0.12 per diluted share, due to the adoption of SFAS 123(R), and costs associated with the previously announced lease exit of $8.3 million after-tax, or $0.13 per diluted share.

The company reported revenues of $825.4 million versus $798.7 million in the prior year period. Net income for fiscal 2006 totaled $103.5 million, or $1.59 per diluted share, versus $134.5 million, or $1.86 per diluted share, reported in the prior year.

Fourth Quarter Fiscal 2006 Revenues Highlights
Revenues for fourth quarter fiscal 2006 across each of the company’s four operating segments were as follows:

	•		Strategy Machine® Solutions revenues increased to $111.6 million in the fourth quarter compared to $109.6 million in the prior year quarter, or by 1.8%, primarily due to an increase in revenues from fraud, originations, and collections and recovery solutions, offset by a decline associated with insurance solutions and consumer scoring products.
	•		Scoring Solutions revenues were $45.5 million in the fourth quarter compared to $47.8 million in the prior year quarter, or a decrease of 4.8%, primarily due to a decrease in revenues derived from risk scoring services at the credit reporting agencies.
	•		Professional Services revenues increased to $37.0 million in the fourth quarter from $33.4 million in the prior year quarter, or by 10.9%, primarily due to an increase in revenues from strategic consulting services and implementation services for EDM products.
	•		Analytic Software Tools revenues increased to $13.2 million in the fourth quarter compared to $12.6 million in the prior year quarter, or by 5.1%, due to an increase in revenues generated from sales of the Blaze Advisor™ product.

Fiscal 2006 Revenues Highlights
Revenues for fiscal 2006 across each of the company’s four operating segments were as follows:

	•		Strategy Machine® Solutions revenues increased to $457.2 million from $453.7 million in the prior year period, or by 0.8%, primarily due to growth in fraud solutions, consumer scoring products and collections and recovery solutions, offset by a decline associated with marketing services and insurance solutions.
	•		Scoring Solutions revenues increased to $177.2 million from $167.3 million in the prior year period, or by 5.9%, primarily due to an increase in revenues from risk scoring services at the credit reporting agencies, and PreScore® Service.
	•		Professional Services revenues increased to $145.3 million from $129.6 million in the prior year period, or by 12.1%, primarily due to an increase in revenues from strategic consulting services and implementation services for EDM products, offset by a decline in consulting services related to precision marketing.
	•		Analytic Software Tools revenues were $45.7 million compared to $48.0 million in the prior year period, or a decrease of 4.8%, due to a decline in revenues generated from sales of the Blaze Advisor™ product.

Bookings Highlights
The bookings for the fourth quarter were $112.6 million versus $109.7 million in the same period last year. The company defines a “new booking” as estimated future contractual revenues, including agreements with perpetual, multi-year and annual terms. Management regards the volume of new bookings achieved as one indicator of future revenues, but they are not comparable to, nor should they be substituted for, an analysis of the company’s revenues.

Balance Sheet and Cash Flow Highlights
Cash and cash equivalents, and marketable security investments were $267.8 million at September 30, 2006, as compared to $288.1 million at September 30, 2005. Significant changes in cash and cash equivalents from September 30, 2005 include cash provided by operations of $199.0 million for fiscal 2006 and $64.2 million received from the exercise of stock options and stock issued under an employee stock purchase plan. Cash used during fiscal 2006 includes $31.4 million related to purchases of property and equipment and $256.5 million to repurchase company stock.

Outlook
The company expects revenues for first quarter fiscal 2007 of approximately $210.0 million and earnings per diluted share, to be approximately $0.48. The company expects revenues for fiscal 2007 of approximately $870.0 million and earnings per diluted share, to be approximately $2.10. The earnings per diluted share, guidance include compensation expense related to SFAS 123(R).

New Stock Repurchase Program
Fair Isaac also announced today that its Board of Directors has approved a common stock repurchase program to acquire up to $500 million of the company’s outstanding common stock. This new program replaces the Company’s previous repurchase program announced on August 29, 2006, which had authorized the company to acquire up to $250 million of outstanding stock. Under the previous program, Fair Isaac purchased approximately 2.4 million shares of its common stock, at an aggregate cost of approximately $85.3 million. The stock repurchase program, which is open-ended, allows the company to repurchase its shares from time to time in the open market and in negotiated transactions.

Company to Host Conference Call
The company will host a conference call today at 5:00 p.m. Eastern Time (4:00 p.m. Central Time/2:00 p.m. Pacific Time) to discuss its fourth quarter and fiscal 2006 results, and outlook for fiscal 2007.

	1.		all claims arising out of or relating to my employment with FIC or the termination of that employment;
	2.		all claims arising out of or relating to the statements, actions, or omissions of the Company;
	3.		all claims for any alleged unlawful discrimination, harassment, retaliation or reprisal, or other alleged unlawful practices arising under any federal, state, or local statute, ordinance, or regulation, including without limitation, claims under Title VII of the Civil Rights Act of 1964, the Age Discrimination in Employment Act, the Americans with Disabilities Act, 42 U.S.C. § 1981, the Employee Retirement Income Security Act, the Fair Credit Reporting Act, the Equal Pay Act, the Worker Adjustment and Retraining Notification Act, the Family and Medical Leave Act, the Sarbanes-Oxley Act, the Minnesota Human Rights Act, the Minneapolis Civil Rights Ordinance, and workers’ compensation non-interference or non-retaliation statutes (such as Minn.

			However, My Claims do not include any claims that the law does not allow to be waived; I may have to receive benefits under any employee benefit plan of the Company in which I am now a participant; any claims that may arise after the date on which I sign this Release; any claims for breach of the Agreement; or any rights I may have to indemnification from the Company under applicable law, the charter documents of the Company, or any related insurance policy maintained by the Company.

Agreement to Release My Claims. I will receive consideration from FIC as set forth in the Agreement if I sign and do not rescind this Release as provided below. I understand and acknowledge that such consideration includes valuable consideration in addition to anything of value that I would be entitled to receive from FIC if I did not sign this Release or if I rescinded this Release. In exchange for that consideration I give up and release all of My Claims. I will not make any demands or claims against the Company for compensation or damages relating to My Claims. The consideration that I am receiving is a fair compromise for the release of My Claims.

Additional Agreements and Understandings. Even though FIC will provide consideration for me to settle and release My Claims, the Company does not admit that it is responsible or legally obligated to me. In fact, the Company denies that it is responsible or legally obligated to me for My Claims, denies that it engaged in any unlawful or improper conduct toward me, and denies that it treated me unfairly.

Advice to Consult with an Attorney. I understand and acknowledge that I am hereby being advised by the Company to consult with an attorney prior to signing this Release and I have done

so. My decision whether to sign this Release is my own voluntary decision made with full knowledge that the Company has advised me to consult with an attorney.

Period to Consider the Release. I understand that I have 21 days from the day that I receive this Release, not counting the day upon which I receive it, to consider whether I wish to sign this Release. If I sign this Release before the end of the 21-day period, it will be my voluntary decision to do so because I have decided that I do not need any additional time to decide whether to sign this Release. I also agree that any changes made to this Release or to the Agreement before I sign it, whether material or immaterial, will not restart the 21-day period.

My Right to Rescind this Release. I understand that I may rescind this Release at any time within 15 days after I sign it, not counting the day upon which I sign it. This Release will not become effective or enforceable unless and until the 15-day rescission period has expired without my rescinding it.

Procedure for Accepting or Rescinding the Release. To accept the terms of this Release, I must deliver the Release, after I have signed and dated it, to FIC by hand or by mail within the 21-day period that I have to consider this Release. To rescind my acceptance, I must deliver a written, signed statement that I rescind my acceptance to FIC by hand or by mail within the 15-day rescission period. All deliveries must be made to FIC at the following address:

		Richard Deal
		Fair Isaac Corporation
		901 Marquette Avenue
		Suite 3200
		Minneapolis, MN 55402

If I choose to deliver my acceptance or the rescission of my acceptance by mail, it must be (1) postmarked within the period stated above; and (2) properly addressed to FIC at the address stated above.

Interpretation of the Release. This Release should be interpreted as broadly as possible to achieve my intention to resolve all of My Claims against the Company. If this Release is held by a court to be inadequate to release a particular claim encompassed within My Claims, this Release will remain in full force and effect with respect to all the rest of My Claims.

My Representations. I am legally able and entitled to receive the consideration being provided to me in settlement of My Claims. I have not been involved in any personal bankruptcy or other insolvency proceedings at any time since I began my employment with FIC. No child support orders, garnishment orders, or other orders requiring that money owed to me by FIC be paid to any other person are now in effect.

I have read this Release carefully. I understand all of its terms. In signing this Release, I have not relied on any statements or explanations made by the Company except as specifically set forth in the Agreement. I am voluntarily releasing My Claims against the Company. I intend this Release and the Agreement to be legally binding.
