                            SECOND AMENDMENT TO THE
                CHART HOUSE ENTERPRISES, INC. SEVERANCE PAY PLAN
                ------------------------------------------------

WHEREAS, Chart House Enterprises, Inc. (the "Company") has established and
maintains the Chart House Enterprises, Inc. Severance Pay Plan, effective June
10, 1999, as amended by that certain First Amendment to the Chart House
Enterprises, Inc. Severance Pay Plan dated December 9, 1999 ("Plan"), for the
benefit of its eligible employees;

WHEREAS, the terms of the Plan reserve to the Company the right to amend the
Plan at any time, retroactively or otherwise;

WHEREAS, the Board of Directors of the Company has, in its sole discretion and
as provided for in the Plan, established severance pay benefits for the
President and Chief Executive Officer;

WHEREAS, the Company has created additional "position categories" as defined in
the Plan for Base Severance Pay and Supplemental Severance Pay including
"Executive Vice President" and "Senior Director";

WHEREAS, the existing Plan benefits for officers and senior directors of the
Company do not reflect competitive market conditions and do not appropriately
align with the severance benefits established for the President and Chief
Executive Officer; and

"Position Categories" as set forth therein and to provide for amended base and
supplemental severance pay benefits for the Company's officer and senior
director positions to reflect competitive market conditions and more
appropriately align with the severance pay benefits afforded the President and
Chief Executive Officer under the Plan.

WHEREAS, the Company further desires to amend language contained in the
"Supplemental Severance Pay" portion of the Plan to (i) provide that the Plan
Committee shall have sole and absolute discretion to award supplemental
severance benefits under the Plan and (ii) replace the previous formula for
awarding supplemental severance pay benefits with an established range of
proposed benefits.
