All of the stock options shown above have a four year vesting period with one fourth vested immediately and the balance vesting monthly after the first year. The options are immediately exercisable in full, however, in the event the officer's service to our Company is terminated, any unvested option shares that have been exercised remain subject to repurchase by our Company at the price equal to the option exercise price.

        The Named Executive Officers did not exercise any options in fiscal year 2003. The following table provides information with respect to unexercised options held as of December 31, 2003, by the Named Executive Officers:

Fiscal Year-End Option/SAR Values

---

(1)

The fiscal year-end value of "in-the-money" stock options and SARs granted in tandem with such options represents the difference or a portion of the difference between the exercise price of such options and SARs, respectively, and the fair market value of our common stock as of December 31, 2003. The fair market value of our common stock on December 31, 2003 was $7.15 per share, the closing price of the common stock reported on the American Stock Exchange on such date.

(2)

A portion of the options are not yet vested and any unvested option shares that are exercised remain subject to repurchase by our Company at a price equal to the option exercise price.

(3)

Includes options to purchase 140,000 shares of common stock that have SARs granted in tandem with such options. The SARs are for 35% of the difference between the fair market value of the common stock at the time the related option is exercised and the exercise price of $15.00, up to a maximum of $20 per share.

LONG-TERM INCENTIVE PLAN AWARDS IN LAST FISCAL YEAR(1)

---

(1)

No award will be paid unless our Company achieves an 8% average annual return on average monthly equity. Awards are based on total return to stockholders (stock price appreciation plus dividends) for our Company compared to a peer group of 19 other mortgage companies. If our Company's return to stockholders for the performance period falls below the 40th percentile, no award is earned, at the 40th percentile the minimum award is earned, at the 60th percentile the target award is earned and at the 80th percentile and above the maximum award is earned.

(2)

Payouts will be calculated as a percentage of aggregate base salary for the performance period and are estimated based on actual salary in 2003 and current base salaries for 2004. Our CEO may earn 67.5%, 135% or 202.5% of his base salary at the minimum, target and maximum levels, respectively. Each of our other Executive Officers may earn 47.5%, 95% and 142.5% of his or her base salary at these levels.

(3)

Performance is measured over a two year period beginning January 1, 2003.

Compensation of Directors

        Each non-employee director of our Company will be paid annual compensation of $22,000 with an additional $1,200 paid for attendance at a regularly scheduled Board meeting, $1,000 for attendance at a special or committee meeting and half of these amounts paid for telephonic meetings. Committee chairpersons receive additional annual compensation as follows: Compensation and Corporate Governance Committee, $3,000; and Audit Committee, $5,000. All directors will be reimbursed for any

6

---

expenses related to attendance at meetings of the Board or committees of the Board or our stockholders meeting. Currently, in addition to cash compensation, each non-employee director of our Company receives an initial grant of options to purchase 7,500 shares of the common stock of our Company at the time he begins service as a director. The initial grant is at fair market value and will vest over a three-year period (one-third every twelve months). Thereafter, each non-employee director of our Company who has served continuously for at least six months as of the date of that year's annual meeting of stockholders, receives a grant of options to purchase 7,500 shares of the common stock of American Residential on the date of such meeting. Such grant is at fair market value and will vest after one year. We intend to amend our option plan or adopt a new plan that will provide for restricted stock awards. The non-employee directors will then receive an annual restricted stock award of 2,300 shares and an annual option grant of 3,300 shares.

Employment Contracts and Termination of Employment and Change-in-Control Arrangements

        All options and SARs granted to date pursuant to our 1997 Stock Incentive Plan and our 1997 Stock Option Plan contain provisions pursuant to which unvested portions of outstanding options become fully vested upon a change of control in our Company, as defined under the relevant plan.

        We entered into an Amended and Restated Employment Agreement with each of our executive officers effective January 1, 2003. The term of each agreement was one year. Under the agreements, if an executive officer is terminated without cause, he or she would receive one year's base salary plus bonus as severance pay and would receive one year of continued health care benefits. The agreements also specified an initial base salary and a potential bonus of up to 100% of base salary, however, both of these terms were modified during the year by actions taken by the Compensation Committee (see our Summary Compensation Table).

        In December 2003 and January 2004, our Compensation Committee approved terms for new Executive Employment Agreements. These agreements have not been finalized, however, the terms that were approved are as follows:

•

Mr. Robbins—base salary of $463,800, a potential bonus of 135% of base salary, and in the event of termination of his employment, severance of up to two years of base salary, target bonus, and health care benefits continuation, plus reimbursement of any federal excise taxes imposed by the IRS with respect to severance amounts deemed to be parachute payments in the event of a change of control.



•

Mr. Fuller—base salary of $318,816, a potential bonus of 120% of base salary, and in the event of termination of his employment, severance of up to eighteen months of base salary, target bonus, and health care benefits continuation, plus reimbursement of any federal excise taxes imposed by the IRS with respect to severance amounts deemed to be parachute payments in the event of a change of control.



•

Ms. Berry—base salary of $255,150, a potential bonus of 120% of base salary, and in the event of termination of her employment, severance of up to eighteen months of base salary, target bonus, and health care benefits continuation, plus reimbursement of any federal excise taxes imposed by the IRS with respect to severance amounts deemed to be parachute payments in the event of a change of control.



•

Ms. Faulk—a base salary of $214,500, a potential bonus of 120% of base salary, and in the event of termination of her employment, severance of up to eighteen months of base salary, target bonus, and health care benefits continuation, plus reimbursement of any federal excise taxes imposed by the IRS with respect to severance amounts deemed to be parachute payments in the event of a change of control.

        The Compensation Committee has also approved the terms of a supplemental executive retirement plan, which has not yet been finalized. That plan will also contain provisions providing for acceleration of benefits in the event of a change of control of our Company.

Compensation Committee Interlocks and Insider Participation

        Dr. Riedy, Mr. Johnson and Mr. John Rocchio served on our Compensation Committee in 2003. None of these members have ever been officers or employees of our Company or any of its subsidiaries. Mr. Rocchio resigned as a director in March 2004. See Item 13.

In addition, our Company agreed to nominate Mr. Rocchio for re-election at subsequent annual meetings of stockholders, provided that the Manager and certain TCW entities collectively beneficially owned at least 800,000 shares of common stock of our Company. Mr. Rocchio is President of the Manager and is a Managing Director of entities affiliated with the TCW Group, Inc.

        In connection with the Buy-Out Transaction, we entered into a Senior Subordinated Secured Revolving Loan Agreement (the "Loan Agreement") with certain TCW entities including TCW/Crescent Mezzanine Partners, L.P., TCW/Crescent Mezzanine Trust, TCW/Crescent Mezzanine Investment Partners, L.P., Crescent/Mach I Partners, L.P and TCW Shared Opportunity Fund II, L.P. (collectively, the "TCW Entities"). The Loan Agreement allowed us to borrow up to $5 million on a revolving basis for one year following the date of the Loan Agreement. Interest was payable at the end of each calendar quarter based on outstanding borrowings. The Loan Agreement also provided that we could extend the Loan Agreement for two additional, one-year periods. We exercised our option and extended the Loan Agreement for two additional periods. The loan was paid off and the Loan Agreement was retired as of April 12, 2004.

        In March 2004, the Manager sold 1.1 million shares of our common stock to The D3 Family Funds in a negotiated private transaction (the "Stock Sale"). As a result of the Stock Sale, the Manager and the TCW Entities collectively no longer hold at least 800,000 shares of our common stock and the Manager no longer has a right to designate a Board nominee. Concurrently with the consummation of the Stock Sale transaction, Mr. Rocchio resigned from our Board and David Nierenberg, upon the recommendation of the Nominating and Corporate Governance Committee, was appointed by the Board to fill the vacancy created by Mr. Rocchio's resignation. Effective upon the consummation of the Stock Sale, we amended our Stockholder Rights Plan to remove the Manager and the TCW Entities as parties permitted to own up to 25% of our outstanding common stock, as permitted by the original Stockholder Rights Plan, and to add The D3 Family Funds as parties permitted to own up to 18% of our outstanding common stock.

        Mr. Nierenberg is the President of Nierenberg Investment Management Company. Since 1996, his firm has managed The D3 Family Funds, consisting of five private investment partnerships based in Camas, Washington.
