    Agreements with the Company. The Employment Agreement of Mr. Hellman had an
    initial term expiring December 31, 1998. In fiscal 1998, Mr. Hellman's
    Employment Agreement was extended through December 31, 2003. Mr. Ruud and
    Mr. Sucic are parties to similar Employment Agreements with the Company: Mr.
    Ruud's having an initial term expiring January 1, 2001; Mr. Sucic's having
    an initial term expiring on February 11, 2001. Through these Employment
    Agreements, Mr. Hellman, Mr. Ruud and Mr. Sucic are entitled to receive
    annual base compensation of $195,000, $185,000, and $175,000, respectively.
    In addition, Mr. Hellman, Mr. Ruud and Mr. Sucic will each be entitled to
    receive a bonus in amounts determined by the Compensation Committee. These
    Employment Agreements provide for annual increases in annual base
    compensation in amounts determined by the Compensation Committee during the
    term of these Employment Agreements. For fiscal 1999, Messrs. Hellman, Ruud,
    Fisi and Sucic received annual base compensation of $200,000, $192,500,
    $175,000 and $175,000, respectively. The Compensation Committee has not yet
    determined whether there will be an increase in compensation for Messrs.
    Hellman, Ruud, Fisi, and Sucic in fiscal 2000. Under the Employment
    Agreements, Mr. Hellman, Mr. Ruud and Mr. Sucic participate in Company
    sponsored life, health, and disability insurance coverage. Also includes
    compensation deferred pursuant to the Company's 401(k) deferred compensation
    plan.

(2) Perquisites provided to Mr. Hellman included club dues ($21,600 in fiscal
    1998 and $20,785 in fiscal 1997) and automobile use and insurance ($9,771 in
    fiscal 1998 and $9,780 in fiscal 1997). Perquisites provided to Mr. Fisi
    included club dues ($7,854) and automobile use and insurance ($11,875).

(3) Mr. Ruud was elected to the office of Vice Chairman effective on January 2,

    from Ruud Lighting, Inc. prior to its acquisition by the Company on January
    2, 1998.

(4) Perquisites provided to these executive officers consisted primarily of
    automobile use, automobile insurance, club dues, the total of which did not
    exceed 10% of the person's salary and bonus.

(5) Since 1993, the Company and its predecessors have maintained split dollar
    life insurance policies with respect to certain key employees. In order to
    reduce expenses, the split dollar life insurance program was terminated
    effective June 30, 1999. This program applied to approximately 25 employees,
    including Messrs. Hellman, Fisi and Sucic. This program provided life
    insurance benefits and a cash value benefit which vested over a ten year
    period and was to be received upon termination of employment or retirement
    from the Company. In connection with the termination of this program the
    Company accelerated the vesting of the cash value benefits, providing full
    vesting as to the cash value in each policy. For fiscal year 1999, the
    amounts indicated represent the incremental value of the cash value benefits
    each Executive Officer received as a result of normal and accelerated
    vesting. For fiscal year 1998 and 1997 the amounts indicated represent the
    split dollar life insurance premiums. For fiscal 1999 the amounts include
    Company contributions to 401(k) plan in the amounts of $4,271, $2,776,
    $5,065 and $1,384 for Messrs. Hellman, Fisi, Ruud and Sucic respectively.

                           COMPENSATION OF DIRECTORS

     All directors of the Company receive reimbursement for reasonable
out-of-pocket expenses incurred in connection with meetings of the Board of
Directors. In addition, in the fiscal year ended June 30, 1999, the nonemployee
directors were compensated $2,500 for each meeting of the full-board attended.
Such directors will be entitled to a minimum of $10,000 if they attend 75% or
more meetings of the board and committees to which they belong. No director who
is an employee of the Company will receive separate compensation for services
rendered as a director.

     In December 1995, the Company granted options to purchase 9,600 shares of
Common Stock under the Incentive Award Plan to each of its nonemployee
directors. These options were granted at an exercise price of $10.00 per share.
Of these options 9,600 shares each are exercisable within 60 days of the date of
the Proxy Statement by Messrs. Beam and Filson. In January, 1996, the Company
granted options to purchase 9,600 shares of Common Stock at $10.25 per share
under the Incentive Award Plan to Mr. Harada upon appointment to the Board of
Directors, all of which are currently exercisable. In June 1996, the Company
granted options to purchase 15,000 shares of Common Stock at $17.00 per share
under the Incentive Award Plan to Mr. Tunstall upon appointment to the Board of
Directors, all of which options are currently exercisable. In June 1996, each
nonemployee director other than Mr. Harada and Mr. Tunstall (Messrs. Beam and
Filson) was granted options to purchase an additional 5,400 shares at an
exercise price of $17.00 per share. All of these options are currently
exercisable. In September 1997, Mr. Filson was granted an option to purchase
30,000 shares of Common Stock at $23.75 per share of which 18,000 shares are
currently exercisable. Each grant was made at the market price of the Company's
Common Stock on the date of grant. Each option will vest 25% in the first year,
35% in the second year, and 40% in the third year from the date of grant.

     In fiscal 1999, Mr. Filson provided consulting services to the Company and
received fees in the amount of $99,996. In calendar 1999, Mr. Filson has agreed
to provide consulting services to the Company.

                             EMPLOYMENT AGREEMENTS

respectively. The Compensation Committee has not yet determined whether there

fiscal 2000. Under these Employment Agreements, Mr. Hellman, Mr. Ruud and Mr.
Sucic participate in Company sponsored life, health and disability insurance
coverage. Pursuant to their Employment Agreements, Mr. Hellman has agreed not to
compete with the Company for a period of two years after termination of
employment, and Messrs. Ruud and Sucic have agreed not to compete with the
Company for a period of three years after termination of employment.

     In the event the Company terminates the Employment Agreements without cause

entitled to receive all payments and benefits through the remainder of the term
of the Employment Agreement. In the event the Employment Agreements are

Company for Fiscal 1999. On October 11, 1999, the Board of Directors determined

Award Plan, the Billion Dollar Market Capitalization Plan, or the 1998 Incentive
Award Plan will be approved by the entire Board of Directors.

ITEM 13.  CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

                CERTAIN TRANSACTIONS WITH DIRECTORS AND OFFICERS

     The Company was formed on May 19, 1995, and acquired ownership, primarily
by merger (the "Combination") of 17 affiliated operating corporations that were
previously under common ownership and management (the "Predecessors").

     On September 15, 1995, one of the Predecessors transferred its nonlamp
assets to H&F Five, Inc., a company owned by Messrs. Hellman, Fisi and certain
other employees of the Company, for a demand promissory note from H&F Five, Inc.
in the amount of $200,000 bearing interest at 8.5% per annum. Total principal
and accrued interest at June 30, 1999 was $220,000, which was the largest amount
outstanding at any time during fiscal 1999.

     In fiscal 1999, Mr. Filson provided consulting services to the Company and
received fees in the amount of $99,996. In calendar 1999, Mr. Filson has agreed
to provide consulting services to the Company.

     Mr. Harada, a director of the Company, is an executive officer, director,
and a shareholder of Venture Lighting, Japan ("Venture Japan"), formerly known
as Koto Luminous Ltd., a Japanese manufacturer and marketer of lighting
products. Venture Japan owns 142,268 shares of the Company, which were acquired
in the Combination as a result of its investment in a Predecessor. In April
1997, the Company purchased a 30% equity interest in Venture Japan. In November
1998, this equity interest was exchanged for nonvoting preferred stock in
Venture Japan. Additionally, Mr. Harada and members of his family control Wakoh
Corporation, a Japanese corporation. Wakoh Corporation and the Company are each
50% joint venture partners in Pacific Lighting, Inc., a British Virgin Islands
holding company. The Company uses Pacific Lighting to own and hold a number of
the Company's joint venture investments. Venture Japan is the Company's sole
trading partner in Japan and, as a result, the Company supplies Venture Japan
with materials, lamps and equipment. The Company had sales of approximately
$625,000 in fiscal 1999 to Venture Japan.

     On January 22, 1996, two subsidiaries of the Company each entered into a
six-year Aircraft Operating Agreement with Levetz Investments, Inc. ("Levetz"),
an unrelated Ohio corporation, for the purpose of chartering a 1986 Beechcraft
King Air 300 airplane (the "King Air Aircraft"), which Levetz leased from
LightAir Ltd. ("LightAir"), an Ohio limited liability company owned by Mr.
Hellman (80%) and Mr. Fisi (20%). On May 27, 1997, the Company entered into a
ten-year Aircraft Dry Lease Agreement with LightAir for the purpose of leasing a
1993 Lear Jet 60 airplane (the "Lear Aircraft"). In each case, the leased
airplanes enabled the Company to have air service into locations which are not
adequately served by commercial carriers. On May 6, 1998, LightAir sold the 1986
King Air Aircraft. On April 13, 1998, LightAir purchased a 1991 Beechcraft King
Air 350 airplane (the "Replacement King Air Aircraft") which Levetz leased from
LightAir on the same terms as the original King Air Aircraft; however, there was
no commitment by the Company or any subsidiary for a minimum number of flight
hours for the Replacement King Air Aircraft (one of the subsidiaries had
committed to a minimum of 200 flight hours per year on the King Air Aircraft,
and another subsidiary had committed to a minimum of 75 flight hours per year on
the King Air Aircraft). The Company and its subsidiaries were required to pay
$950 per flight hour on the Replacement King Air Aircraft for the first 275
hours, and $550 per flight hour thereafter, plus operating and maintenance
expenses. The Company had committed to a minimum of 260 flight hours per year on
the Lear Aircraft. The lease rate for the Lear Aircraft was $2,500 per flight
hour, plus operating costs and maintenance expenses. Levetz entered into a
separate Aircraft Dry Lease Agreement with LightAir for use of the Lear Aircraft
when not in use by the Company. In addition, the Company has utilized a Saab 340
Aircraft (the"Saab Aircraft") on an hourly rental basis. The Saab Aircraft was
originally owned by LightAir and was subsequently transferred to LightAir II
Ltd. Messrs. Hellman and Fisi guaranteed the repayment of $2.8 million of
indebtedness incurred to purchase the Replacement King Air aircraft; the
repayment of $8.4 million of indebtedness incurred to purchase the Lear
Aircraft; and $3.0 million of indebtedness to purchase the Saab aircraft.
Payments to LightAir totalled approximately $554,000 in fiscal 1997; $2,071,000
in fiscal 1998, and $588,000 in fiscal 1999. In addition, at June 30, 1999, the
Company had a $59,000 payment due to LightAir. LightAir paid certain rebates and
reimbursements of amounts paid by the Company. Unpaid portions of these amounts
were recorded as non interest bearing receivables of the Company. The largest
amount
                                       10
<PAGE>   12

outstanding with respect to these receivables during fiscal 1999 was $137,000.
There were no such receivables at June 30, 1999.

     On May 20, 1998, LightAir II Ltd. ("LightAir II"), an Ohio limited
liability company owned by Mr. Hellman (50%) and Mr. Ruud (50%), acquired a 1988
Cessna Citation III aircraft. The Citation III was chartered to the Company at
an average of $2,000 per hour prior to January 1999 and $2,400 per hour
thereafter. Scott Air Charter of Milwaukee, Wisconsin is the charter broker for
the plane. Messrs. Hellman and Ruud guaranteed the repayment of $6.4 million of
indebtedness incurred to purchase the Citation III. Following transfer to
LightAir II of the Saab aircraft, LightAir II made the Saab aircraft available
to the Company on the same terms as were made available by LightAir. Commencing
in January 1999 the arrangements with LightAir II were changed to provide for
minimum payments of $55,000 per month for the Saab aircraft. The hourly usage
rates for the plane were reduced from $2,000 per hour to $1,100 per hour for the
Saab Aircraft. LightAir II has entered into arrangements to sell both of its
aircraft and the minimum payment was reduced to $33,500 with respect to the Saab
aircraft. The planes are not expected to be used for charter by the Company
pending sale. Payments to LightAir II during fiscal 1998 totalled $90,000 and
approximately $1,030,000 in fiscal 1999. In addition, at June 30, 1999, the
Company had a $102,000 payment due to LightAir II.

     On January 2, 1998, the Company acquired all of the capital stock of Ruud
Lighting, Inc. Mr. Ruud received approximately $17.8 million and 1,502,857
shares of Common Stock in the transaction. Mr. Ruud's adult children received,
in the aggregate, approximately $9.3 million and 782,857 shares of Common Stock
in connection with the Company's acquisition of Ruud Lighting. In November 1997,
certain shareholders of Ruud Lighting, including Mr. Ruud, purchased from Ruud
Lighting undeveloped real estate contiguous to its existing facility, for
$345,000. The terms of the transactions were determined by arm's-length
negotiation among the parties.

     Pursuant to a loan agreement dated October 8, 1998 between the Company and
Mr. Hellman, its Chairman and Chief Executive Officer (the "Hellman Loan
Agreement"), the Company has loaned $9,000,000 to Mr. Hellman for a one-year
term at the rate of 8%. The loan was made following approval by the Company's
Board of Directors (Messrs. Hellman and Fisi did not participate in the
deliberations). The proceeds of the loan were used to reduce the outstanding
principal balance of a loan from Prudential Securities Incorporated ("PSI"),
which is secured by 2,053,070 shares of Company Common Stock owned by Mr.
Hellman and Hellman Ltd. (the "Hellman Personal Shares"). In connection with the
loan, the Board asked for and received Mr. Hellman's agreement to extend the
term of his employment agreement to December 31, 2003. The Hellman Loan
Agreement prohibits Mr. Hellman from encumbering the Hellman Personal Shares in
any manner except pursuant to existing agreements governing Mr. Hellman's margin
account at PSI, without consent of the Board's representative. The loan is
partially secured by certain real estate owned by Mr. Hellman. Mr. Hellman has
paid accrued interest on the loan through October 6, 1999. The principal on the
loan was due on October 6, 1999. Members of the Board of Directors of the
Company and Mr. Hellman are discussing alternative payment terms which will
achieve the Board's original business objectives in making the loan and meet the
Company's current business needs. The Directors and Mr. Hellman believe that
these discussions will be completed by January 2000. The Board has informed Mr.
Hellman that the Company may require immediate payment during these discussions
if the Company requires the payment to prevent an unacceptable strain on cash
resources.

     Diane Hellman, Mr. Hellman's wife, has served the Company in various
marketing positions since 1985, and currently serves as Vice President of Sales
and Marketing of Venture Lighting International, Inc. In fiscal 1999, Mrs.
Hellman's salary, benefits and perquisites (including the normal vesting and a
one-time charge for accelerated vesting resulting from the termination of the
split dollar life insurance program) were $126,731. Brian Hellman, Mr. Hellman's
son, has served the Company in various positions since 1992, and currently
serves as Senior Business Analyst of Venture Lighting International, Inc. In
fiscal 1999, Brian Hellman's salary, benefits and perquisites (including the
normal vesting and a one-time charge for accelerated vesting resulting from the
termination of the split dollar life insurance program) were $92,163. Deborah
Rogers, Mr. Hellman's sister-in-law, has served the Company in various positions
since 1994, and currently serves as Regional Sales Manager of Venture Lighting
International, Inc. In fiscal 1999, Ms. Rogers' salary, benefits and perquisites
were $69,857. Susan Ruud, Mr. Ruud's wife, has served the Company since 1998,
and served Ruud Lighting in various positions since 1982, and currently serves
as Vice President of Human Resources of the Company. In fiscal 1999,
                                       11
<PAGE>   13

Mrs. Ruud's salary and benefits were $66,846. Christopher Ruud, Mr. Ruud's son,
has served the Company since 1998, and served Ruud Lighting in various positions
since 1986, and currently serves as Vice President of Continuous
Improvement/Human Resources of Ruud Lighting. In fiscal 1999, Christopher Ruud's
salary and benefits were $91,447.

     The Company does not intend to enter into any material transaction with
officers or directors, or their family members, without the approval of a
majority of the disinterested directors in the future.

                                 GE TRANSACTION

     On October 6, 1999, GE made an investment in the Company of $20,554,000.
The additional capital resources provided by the agreed investment by GE are
expected to provide additional flexibility to pursue opportunities in the metal
halide business. In addition, GE and the Company have entered into a five year,
renewable agreement for the supply of metal halide salts to GE. The Company and
GE are in discussions with respect to other supply arrangements. The Company
anticipates that the GE investment and the expansion which it will permit will
result in an expanded supplier-customer relationship with GE, enhancing the
Company's earnings and competitive position in the metal halide marketplace. See
Item 7 under "Recent Developments" -- General Electric Company Investment."

     The GE investment includes 761,250 shares of the Company's newly-created
Series A Stock convertible at any time into 3,045,000 shares of Company Common
Stock (subject to adjustment). GE also received a Warrant (the "Initial
Warrant") to purchase an additional 1,000,000 shares of Common Stock of the
Company, which is immediately exercisable. GE has been a holder of 535,887
shares of Company Common Stock since the Company's initial public offering in
1995. The Series A Stock, Common Stock issuable on exercise of the Initial
Warrant and the Common Stock held by GE represent (after giving effect to the
shares issued on exercise of the Initial Warrant) approximately 18.9% of the
voting power and equity ownership of the Company. Pursuant to the terms of the
Stock Purchase Agreement, GE is to provide the Company with five nominees as
potential Company's Board of Directors who are not directors, officers,
employees or 10% shareholders of GE. The Company is required to cause the number
of such nominees serving on the Board to be equal to the greater of 20% of the
number of members of the Board or the number of members which most nearly
corresponds to GE's percentage ownership interest in the Company.

     The proceeds of the GE transaction have been applied principally to the
reduction of short-term liabilities and outstanding amounts under the Company's
principal bank credit facility.
