hereof and shall, unless earlier terminated pursuant to Section 6, hereof,
terminate on June 30, 2004 (the "TERM").

writing pursuant to the terms of this Agreement.

business structure.

                  (b) After July 1, 2000, in the event ADLT's Management
proposes that Consultant execute and perform substantial and significant special
assignments which are beyond the scope of this Agreement, Consultant shall be
paid on a per project basis for such special assignments, which amount shall be
determined upon agreement of Management and Consultant.

                  (c) Consultant shall execute and perform his duties as a
director of ADLT outside the scope of this Agreement. ADLT and Consultant agree
that Consultant shall serve the remainder of his current term as a director of

                  4.  CONFIDENTIALITY.

                  (a) Commencing upon the execution of this Agreement,
Consultant shall not disclose, divulge, discuss, copy or otherwise use or suffer
to be used any confidential and secret information with regard to the business,

records, data, operating results, sales, know-how, techniques for sales,
marketing, products, customers, agreements with customers, suppliers, costs and
financial data, memoranda, methods, devices, equipment, processes, procedures,
formulas, pricing and other similar corporate properties of ADLT or its
subsidiaries (collectively "Trade Secrets"). Consultant hereby recognizes and
agrees that the Trade Secrets are valuable, special and unique assets of ADLT's
business and that the disclosure or improper use of such Trade Secrets shall
cause serious and irreparable injury to ADLT, unless and until such information
is in or shall enter the public domain; provided, however, that if the same is
in or shall enter the public domain as the result of Consultant's act, then
Consultant shall continue to keep such Trade Secrets secret and confidential.

                  (b) On or before the end of the Term of this Agreement,
Consultant shall return any and all documents containing any Trade Secrets to
ADLT.

                  (c) Consultant shall not disclose the contents and substance
of this Agreement to any natural person or legal entity except that Consultant
is permitted to disclose the terms of this Agreement to members of Consultant's
immediate family, and his financial, legal and tax-planning advisors, as
necessary. In the event that Consultant reveals the material terms of this
Agreement to members of his immediate family, and/or to his advisors, said
person or person shall be instructed that this is a private settlement and that
the terms of this Agreement may not be revealed to any other person for any
reason whatsoever during the term of this Agreement. As a matter of course,
Consultant may disclose the terms of this Agreement in response to any inquiry
by the Internal Revenue Service or other taxing authority.

                  (d) Consultant agrees that he will not contact any employee or
representatives of ADLT regarding this Agreement, nor discuss its content or the
events regarding the termination of his employment. In the event ADLT determines
that Consultant has violated this provision of non-contact, all contracts with
and offers of ADLT of benefits beyond the date of termination shall be
terminated or withdrawn.

                  (e) Consultant acknowledges that he has signed and delivered
to ADLT a confidentiality agreement, and that Consultant shall continue to abide
by the terms and conditions of such confidentiality agreement.

                  (f) The obligations of Consultant under this Section shall
survive the termination of this Agreement.

                  5.  NON-COMPETITION AND RELATED MATTERS

                  (a) NON-COMPETITION. Consultant agrees that during the Term of
this Agreement, he will not render services within the continent of North
America, directly or indirectly, individually or collectively, own, manage,
operate, join or control, or participate in the ownership, management, operation
or control of, or act as an employee, agent or consultant to, any Conflicting
Organization.

                  (b) ACKNOWLEDGMENT OF REASONABLENESS AND SEVERABILITY.
Consultant acknowledges and agrees that the type and periods of restrictions
imposed in this Agreement are fair and reasonable, and that such restrictions
are intended solely to protect the legitimate interest of ADLT, rather than to
prevent Consultant from earning a livelihood. Consultant recognizes that ADLT
competes with other organizations in the business of designing, marketing and
manufacturing metal halide lamps and any other work as may have been required or
defined by the Board of Directors, and that his access to Confidential
Information and other proprietary information could be used to the detriment of
ADLT. In the event that any restriction set forth in this Agreement is
determined to be overly broad with respect to scope, time or geographic
coverage, Consultant agrees that such a restriction or restrictions should be
modified and narrowed, either by a court or by, so as to preserve and protect
the legitimate interests of ADLT as described in this Agreement, and without
negating or impairing any other restrictions or agreements set forth herein.

                  (c) DEFINITIONS. The following capitalized terms shall
have the meanings ascribed to them below:

                      (i) "BUSINESS" shall mean the primary business of
                      ADLT which is the design, manufacture and marketing
                      of metal halide fixtures, lamps and components
                      thereto.

                      (ii) "CONFIDENTIAL INFORMATION" shall mean
                      information in any form, which is generally not known
                      to the public, and/or is proprietary to ADLT,
                      including without limitation trade secret information
                      about the Business, and also including information
                      relating to research, development, manufacture,
                      purchasing, accounting, engineering (in any form,
                      including software designs), marketing,
                      merchandising, selling, leasing, servicing, finance
                      and business systems and techniques and information
                      used by the ADLT or received by ADLT on a
                      confidential basis from any third party, and customer
                      lists. All information disclosed to Consultant, or to
                      which Consultant has access, whether originated by
                      Consultant or by others, during the period of his
                      relationship with ADLT, which Consultant on a
                      reasonable basis believe to be Confidential
                      Information, or which is treated by ADLT as being
                      Confidential Information, shall be presumed to be
                      Confidential Information.

                      (iii) "CONFLICTING BUSINESS" shall mean any business,
                      process, system or service of any person or
                      organization other than ADLT, in existence or under
                      development, which is the same as or similar to or
                      competes with, or has a usage allied to, the business
                      or any process, system or service concerning the

                      Information.

                 (a) This Agreement shall terminate upon the earlier of (i) a
