EMPLOYMENT AGREEMENTS

In February 1999, the Company entered into an employment agreement with Mr.
Edwards, the Company's President and Chief Executive Officer. This agreement
provides for an annual salary of $315,000 plus a bonus dependent upon the
Company achieving performance goals to be established from time to time by the
Company's Compensation Committee. Further, for calendar 1999, Mr. Edwards was
entitled to a minimum bonus of $150,000. The agreement also provides that Mr.
Edwards would receive an amount equal to two times his annual salary in the
event he no longer serves as President and Chief Executive Officer and such
termination is by the Company without cause or by Mr. Edwards if there has
occurred a material change in his duties, a reduction in his


                                       5
<PAGE>   6

compensation or a "change in control" (as defined below) of the Company. Under
such circumstances, Mr. Edwards would also receive payments under his severance
agreement described below.

        The Company has severance agreements with its executive officers.
Severance agreements currently in effect are with Messrs. Edwards, Doll, Ferry
and Troy. Each of these agreements provides, in essence, that should there be a
"change in control" (as defined) and the officer's employment is terminated
either (i) involuntarily, without just cause, or (ii) voluntarily, if the
officer has determined in good faith that his duties have been altered in a
material respect or there has been a reduction in his compensation or employee
benefits, then upon termination, the officer would be entitled to receive a
severance payment. A "change in control" of the Company is generally defined as
(i) any consolidation or merger of the Company, other than a merger of the
Company in which the holders of the Company's common stock immediately prior to
the merger have at least seventy-five percent (75%) ownership of the voting
capital stock of the surviving corporation immediately after the merger, (ii)
any sale, lease, exchange or other transfer (in one transaction or a series of
related transactions) of all, or substantially all, of the assets of the
Company, (iii) the shareholders of the Company approve any plan or proposal for
the liquidation or dissolution of the Company, (iv) any person shall become the
beneficial owner of thirty percent (30%) or more of the Company's outstanding
common stock, or (v) during any period of two consecutive years, individuals who
at the beginning of such period constitute the entire Board of Directors shall
cease for any reason (except death) to constitute a majority thereof unless the
election, or the nomination for election by the Company's shareholders, of each
new director was approved by a vote of at least two-thirds of the directors then
still in office who were directors at the beginning of the period.

        The sale of the Company's electronics distribution business in January
1999 constituted a "change in control". After the sale of the Company`s
electronics distribution business Messrs. Hough's, Weeks' and Resnick's
corporate functions were no longer needed, their employment ceased and they
received $642,000, $141,000 and $284,000, respectively, under severance
agreements entered into in October 1991, September 1993 and January 1997,
respectively. Additionally, Messrs. Weeks and Resnick each received a payment of
$60,000 in lieu of continued employee benefits under their severance agreements.

        Mr. Edwards' severance agreement entered into in April 1993 provides
that if he is terminated under circumstances giving rise to a severance payment,
the amount of such payment would be 295% of the "base amount" (generally
equivalent to the highest twelve months compensation during such person's last
three years prior to termination). In addition, under his severance agreement
and employment agreement the Company agrees to pay Mr. Edwards the amount of any
excise tax on the payment of any amount which constitutes an "excess parachute
payment" under Section 4999 of the Internal Revenue Code of 1986. The severance
agreements with Messrs. Doll, Ferry and Troy entered into in April 1990, April
1996 and March 1998, respectively, provide that if they are terminated under
circumstances giving rise to a severance payment, the amount of such payment
would be the lesser of 150% of their "base amount" and the maximum amount
payable that would not constitute an "excess parachute payment." In June 1999,
Mr. Doll entered into a second severance agreement having substantially the same
terms except the payment calculation would be 145% of the base amount.

        Mr. Graham had a severance agreement entered into in October 1991
pursuant to which he received $950,000 in February 1999 when Mr. Edwards assumed
the office of President and Chief Executive Officer. Also, in February 1999, Mr.
Graham entered into a three year consulting agreement which provides for annual
payments of $250,000. These payments may be accelerated upon the occurrence of a
"change in control" event. He receives no other payment for his services to the
Company.

        In February 1999, the Company paid Mr. Williams, Bell's former Chairman
of the Board, President and Chief Executive Officer approximately $1,723,000
owing him under his deferred compensation agreement ($1,446,000 ) and consulting
agreement ($277,000). He was also paid an additional $277,000 in lieu of
continued salary as Co-Chairman of the Board. Mr. Williams will receive no
further monies for his services to the Company.

        The Company has entered into Indemnity Agreements with all directors and
all executive officers of the Company after having received shareholder approval
at the Company's 1986 Annual Meeting. The Indemnity Agreements provide for
indemnification of directors and officers in cases where indemnification might
not otherwise have been available.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

        Mr. Cost, who is also a member of the Compensation Committee, is the
Secretary of the Company. During 1999, he received as compensation for his
services as Secretary, in lieu of the annual retainer for being a director, an
amount equal to the annual retainer (approximately $40,000). Effective January
1, 2000, he is being paid $15,000 per year for his services as Secretary. In
addition, he commenced receiving his retirement benefits of $40,000 per year
under the Company's Non-Employee Director's Retirement Plan.

              COMPENSATION STRUCTURE AND COMMITTEE RESPONSIBILITIES

        The Company compensates its executive officers with two basic forms of
compensation: cash (salary and incentive bonus) and stock options. The Company's
earnings for 1997 and 1998 were not sufficient to warrant the payment of bonuses
under the predetermined formula for incentive compensation based upon a minimum
return on shareholders' equity, although special bonuses were awarded in 1998 in
connection with the sale of two major segments of the Company's business.
Further in January and December 1997 and January 1999, executives were awarded
stock options under Bell's stock option plans at an exercise price equal to the
fair market value for the underlying shares on the date of grant. No options
were granted in calendar 1998. Following the Company's $5.70 cash distribution
in June 1999 and the $1.30 cash distribution in December 1999, the exercise
prices were reduced by the amount of the per share distributions.

        The Company's Compensation Committee currently consists of Messrs. Cost,
Craig, Davidson and Rosenberg. The duties of the Committee are to determine the
overall compensation policy for the Company's executive officers, including
specifically fixing the compensation of the chief executive officer.

        The following report is submitted by the Compensation Committee as it
relates to both cash compensation of, and stock options granted to executive
officers of the Company. This report is not deemed "filed" with the Securities
and Exchange Commission and is therefore not intended to be incorporated by
reference in any other document filed by the Company with the Commission.

                      REPORT OF THE COMPENSATION COMMITTEE

        The Company's compensation philosophy is based upon the belief that the
Company's success is the result of the coordinated efforts of all employees
working towards common objectives. Its executive officer compensation program is
composed of base salary, annual incentive cash bonuses and long-term incentive
compensation in the form of stock options.

BASE SALARY

        The Committee attempts to set the base salary levels competitively with
those paid by others in its Peer Group. In determining salaries, the Committee
also takes into account individual experience and performance, past salary
history and specific issues particular to the Company.

ANNUAL INCENTIVE BONUS

        Prior to fiscal 1994, cash bonuses were considered annually and awarded
generally upon a subjective evaluation of the particular officer's performance
for the year and were dependent upon the overall financial achievement of the
Company during the year. For example, bonuses usually were not given in years
where the Company's growth was nominal. Thereafter, the Committee established an
incentive bonus program based upon the return on shareholders' equity and
awarded incentive bonuses for those periods in accordance with such programs.
For each period, no incentive bonus would be earned unless the Company's
earnings exceeded a predetermined percentage minimum return on shareholders'
equity as at the beginning of the period. If that minimum return was achieved,
each executive officer (including the Chief Executive Officer) earned a bonus
based upon the extent to which the Company's actual earnings exceeded the
minimum return on shareholders' equity. For the fiscal years ended December 31,
1997 and 1998, the Company's return on shareholder's equity did not equal or
exceed the predetermined percentage minimum; and therefore, no bonuses were
earned under the formula plan. Although the Company's earnings for 1997 were
less than necessary to achieve the minimum return on shareholders' equity
previously established, the Committee awarded discretionary cash bonuses to six
corporate officers in the aggregate amount of $206,667. The Committee believed
that merit bonuses were justified that year due to the effort expended by such
officers in connection with the integration of the business of Milgray
Electronics which was acquired by the Company in January 1997. For fiscal 1998,
certain officers were granted special cash bonuses relating to the sale of the
Company's electronics distribution and graphics imaging businesses. Each of
these officers was instrumental in completing the sale of these two divisions.
For the 1999 fiscal year, the Committee changed the incentive bonus criteria to
one based on the Company achieving a percentage of predetermined targeted net
income. Under this new program, the Committee awarded a bonus of $225,000 to Mr.
Edwards and bonuses aggregating $389,000 to three other executive officers.
Additionally, special cash bonuses were awarded for that fiscal year to Messrs.
Doll and Troy in recognition of their efforts in resizing the Company after the
sale of the electronics distribution and graphics imaging businesses.

LONG-TERM INCENTIVE PROGRAM

        Currently, the Company's long-term incentive program consists of the
award of stock options to executive officers and other key employees at current
market prices. The grant of options with exercise prices at prevailing market
prices is designed to align executive compensation and shareholder long-term
interests by creating a direct link between long-term executive compensation and
shareholder return as evidenced by increased stock market value.

        The Compensation Committee's current policy is to award significant
amounts of stock options to executive officers and other key employees. Exercise
prices are established equal to the fair market value of Bell's common stock on
the date of grant. Options are usually for a term of five (5) years and become
vested over a period of four (4) years dependent upon continued employment. The
number of stock options granted to executive officers is based upon an
evaluation of the particular officer's deemed ability to influence the long-term
growth and profitability of the Company. Stock options were granted to the
Company's executive officers in January and December 1997 with exercise prices
equal to fair market value at the time of grant. Additionally, Mr. Edwards, Mr.
Ferry, Mr. Doll and Mr. Troy were granted stock options covering 300,000;
150,000; 75,000; and 75,000 shares, respectively, in January 1999.


CHIEF EXECUTIVE OFFICER'S COMPENSATION

        On February 1, 1999, Mr. Edwards became President and Chief Executive
Officer of the Company. His employment arrangements have been previously
described. Salary for the Chief Executive Officer is based upon numerous
factors, the most prominent being salaries earned by chief executive officers of
comparable companies, the individual's past salary history and the complexity of
the Company's business during his term. Mr. Graham had been an Executive Officer
of the Company for over ten years and President and Chief Executive Officer from
January 1998 to February 1999. For the 1998 fiscal year, Mr. Graham received a
base salary of $600,000.

                                          Herbert Davidson and Milton Rosenberg.


                               OTHER COMPENSATION

SAVINGS AND PROFIT SHARING PLAN

        The Company established the Bell Industries' Employees' Savings and
Profit Sharing Plan (the "PSP") in 1973 under which both employees and the
Company may make contributions. The PSP will continue until terminated by the
Board of Directors. Employees must contribute at least 1% of their annual
compensation to participate in the PSP. The Company's contribution to the PSP is
determined by the Board of Directors in its discretion. For the fiscal year
ended December 31, 1999, the Company contributed $340,000 to the PSP.

EXECUTIVE DEFERRED INCOME AND PENSION PLAN

        In July 1993, the Company adopted an Executive Deferred Income and
Pension Plan (the "EDP"). Under the EDP, each officer and such other highly
compensated employees as the Board may designate are eligible to participate.
Each participant may elect a percentage (not more than 10%) of his salary that
he wishes to defer. Initially, the Company matched the amount of the chosen
deferral. Such deferred sums are assigned to employee designated investment
options which are funded through Company-owned life insurance policies. In 1999,
the Plan was amended to eliminate the Company's matching contribution and fully
vested previously unvested Company matching contributions. Effective January 1,
2000, the Plan was amended to reestablish a Company matching contribution in an
amount equal to 50% of a participant's chosen deferral. The maximum annual
Company matching contribution per participant is limited to the lesser of 50% of
the deferred amount or $20,000.

        In the event of an unforeseen emergency, a participant may withdraw his
deferred salary plus accrued earnings but no portion of the matching funds
contributed by the Company. In such an event, the participant would be
ineligible from participating in the EDP for a period of two years. After
reaching age 62 and retiring, a participant may elect to have his benefit paid
in a lump sum or payable over a period of 5 to 15 years.


                                       8
<PAGE>   9

        If a participant voluntarily resigns before age 62, he will be entitled
to receive at age 62 only a pro-rata portion of Company matching funds through
the date of his termination. That proration is based upon the period of EDP
participation; the participant being fully vested after 12 years. If a
participant dies while employed, his beneficiary would receive a lump sum
payment equal to all amounts that have accrued for his benefit through date of
death. If a participant's employment is terminated without cause or after a
change in control, he will receive the same benefit as he would have received if
his employment had been terminated due to death. If a participant is terminated
for cause, or if the Board determines within one year after termination that
cause existed at the time of termination, he will be entitled to receive in a
lump sum payment only the amount attributable to his deferred salary plus
accrued earnings.

DIRECTOR COMPENSATION

        During 1999, directors who were employees (except Mr. Cost) received no
additional compensation for serving on the Board of Directors. Non-employee
directors (including Mr. Cost) received an annual retainer of $40,000, plus
$1,000 for each attendance at a meeting of the Board or a committee thereof
which does not immediately precede or follow a meeting of the Board. In June
1999, the Board eliminated the annual retainer for directors effective January
1, 2000, except in the case of Mr. Craig who will receive an annual retainer of
$25,000. The Company had a directors' retirement plan for non-employee
directors. Under the plan, directors having served at least ten years as a
director after reaching the age of 65 are entitled to receive an annual
retirement benefit of $40,000. Such payments will be made for the number of
years equal to the number of years served as a director or until his or her
death; provided, that a surviving spouse is entitled for a period of five years
after death to continue to receive the same benefits that such director would
have been so entitled to receive. If a director has reached age 60 and ceases to
serve as a director at the request of the Company, he will be entitled to the
same retirement benefits as if he retired at age 65. In the event of a change in
control, a director leaving the Board would be entitled to receive an immediate
lump sum payment of the present value of his accrued retirement benefit. In
January 1996, the Company terminated the directors' retirement plan except to
the extent rights thereunder were vested. The rights of Messrs. Cost and
Rosenberg (each a director for over 20 years) were fully vested under the plan;
and, commencing January 1, 2000, each began receiving their annual retirement
benefit. Messrs. Cost, Craig and Rosenberg are also entitled to receive stock
options under the Company's Non-employee Directors' Stock Option Plan. Under the
Plan, each non-employee director receives options for 10,000 shares upon his
election as a director and an option for 1,000 shares for each year thereafter
in which he is reelected. Pursuant to the Plan, Messrs. Cost, Craig and
Rosenberg each received options covering 10,000 shares in May 1996 when the Plan
was first adopted and options covering 1,000 shares in May 1997, 1998 and
February 2000. Mr. Schwarz received options covering 10,000 shares in February
2000.

        Options granted under the Plan are for a term of five years, vest and
may be exercised six months from the date of grant and when granted have an
exercise price equal to the market price of the Company's common stock on the
date of grant.
