Employment Contract

   Mr. Sugarman is employed as Chairman of the Board, President and Chief
Executive Officer of the Company pursuant to an employment agreement dated
December 3, 1998 and expiring on December 31, 2005. The agreement, which was an
amendment and restatement of his agreement of February 24, 1997, provides that
Mr. Sugarman is to receive an annual base salary of $1,000,000 increased
annually by 10% over the prior year to a maximum of $1,600,000, life insurance
in the face amount of $5,000,000, and an annual bonus in an amount determined
from year to year by the Compensation Committee of the Board of Directors, at
its discretion, and certain additional benefits. The employment agreement is
terminable prior to the expiration of the term of the Agreement (1) by the
Company for cause (as defined therein) and (2) by Mr. Sugarman (a) for cause
(as defined therein), (b) at any time for any reason, after January 1, 2000 or
(c) if Mr. Sugarman ceases to own or control at least 10% of the Common Stock
of the Company. Should the employment agreement be terminated by the Company
without cause or by Mr. Sugarman for cause or for other reasons described in
the preceding sentence, Mr. Sugarman would be entitled to (1) continuation of
all health insurance benefits through the expiration of the term of the
agreement, or for 40 months from termination, whichever period is longer and
(2) a lump sum payment in an amount equal to the greater of (a) two times the
annual base salary, and (b) the amount which would have been payable throughout
the remainder of the term of the agreement or 40 months, whichever is shorter,
provided that if the agreement is terminated within one year following a change
in ownership of the Company (as defined therein), Mr. Sugarman will receive a
lump sum payment equal to 2.99 times the average annual compensation paid to
Mr. Sugarman by the Company during the five years prior to such change in
ownership. In the event of Mr. Sugarman's death or disability he (or his
estate) would be entitled to receive a lump sum payment equal to the greater of
(a) two times the annual base salary and (b) the

                                       49
<PAGE>

amount which would have been payable throughout the remainder of the term of
the agreement and continuation of all health insurance benefits for the
remainder of the term. In the event of Mr. Sugarman's death, the Company would
also be obligated to continue all health insurance benefits for Mr. Sugarman's
immediate family for two years. Upon the expiration of the agreement, the
Company is obligated to pay to Mr. Sugarman a lump sum equal to two times the
then annual base salary and continue all health insurance benefits for two
years. Pursuant to the employment agreement, Mr. Sugarman has agreed during the
term of the agreement, not to render services to, or plan for or organize, a
business which is materially competitive with or similar to the business of the
Company or any of its subsidiaries. In January 2000, Mr. Sugarman voluntarily
authorized the Company to decrease his annual salary to $450,000. In addition,
Mr. Sugarman voluntarily agreed to retroactively cancel the termination payment
due to him at the end of his employment contract. No change to his benefits was
made. Mr. Sugarman, at his discretion, may, at any time, increase his salary to
the current level as stated in his current contract. In such case, no
retroactive salary adjustment will be made.
