Item 1. Changes in Control of Registrant.

      (a) As a result of the filing of an Agreement of Merger with the Secretary
of State of the Sate of California on November 30, 1999 (the "Effective Time")
Florence Acquisition Corp., a California corporation ("Purchaser") and a wholly
owned subsidiary of Targetti Sankey S.p.A., an Italian corporation ("Parent"),
was merged (the "Merger") with and into Tivoli Industries, Inc., a California
corporation (the "Registrant"), with the Registrant continuing as the surviving
corporation (the "Surviving Corporation"), in accordance with that certain
Agreement and Plan of Merger dated as of September 17, 1999, among the
Registrant, the Purchaser and Parent (the "Merger Agreement"). As a result of
the Merger and at the Effective Time, Parent beneficially owned 100% of the
voting securities of the Registrant, and the Surviving Corporation became a
wholly owned subsidiary of Parent, and the Purchaser ceased to exist as a
separate corporate entity.

      Following the Effective Time, and until their respective successors are
duly elected or appointed and qualified, (a) Paolo Targetti, Alvaro Andorlini,
Lorenzo Targetti, Charles Kimmel and Terrence Walsh shall be the directors of
the Surviving Corporation and (b) Lorenzo Targetti shall be the Chairman of the
Board of Directors of the Surviving Corporation, Terrence Walsh shall be the
Chief Executive Officer and Vice Chairman of the Board of Directors of the
Surviving Corporation and Charles Kimmel shall be the President and Chief
Financial Officer of the Surviving Corporation.

      At the Effective Time, by virtue of the Merger and without any action on
the part of the holder thereof: (a) each issued and outstanding share of common
stock, par value $0.001 per share, of the Purchaser ("Purchaser Common Stock")
shall be converted into and become one fully paid and nonassessable share of
common stock, par value $0.001 per share, of the Surviving Corporation
("Surviving Corporation Common Stock") and each certificate representing
outstanding shares of Purchaser Common Stock shall at the Effective Time
represent an equal number of shares of Surviving Corporation Common Stock; (b)
all shares of common stock, par value $0.001 per share, of the Registrant
("Registrant Common Stock") that are owned by the Registrant as treasury stock
and any shares of Registrant Common Stock owned by any Subsidiary of the
Registrant, Parent, Purchaser or any other wholly - owned Subsidiary of Parent
shall be canceled and retired and shall cease to exist and no stock of Parent or
other consideration shall be delivered in exchange therefor; and (c) each issued
and outstanding share of Registrant Common Stock (other than shares to be
canceled in accordance with subsection (b) of this paragraph and other than
shares whose holders exercise dissenters' rights) shall be converted into the
right to receive Four Dollars and Fifty Cents ($4.50) in cash (the "Merger
Consideration"), and all such shares of Registrant Common Stock shall no longer
be outstanding and shall automatically be canceled and retired and shall cease
to exist, and each holder of a certificate representing any such shares shall
cease to have any rights with respect thereto, except the right to receive the
Merger Consideration, upon the surrender of such certificate in accordance with
the terms of the Merger Agreement, without interest.

      All outstanding Registrant Stock Options (defined as options to purchase
Registrant Common Stock held by current and former employees, consultants,
vendors, customers, officers and directors of the Issuer which were granted
under the Registrant's 1994 Stock Option Plan, 1995 Stock Option Plan, 1995
Non-Employee Director Stock Option Plan and the 1997 Equity Incentive Plan),
whether or not then vested or exercisable, shall be made fully vested and
exercisable and canceled by the Registrant immediately before the Effective
Time, and thereafter, the holders' sole right shall be to, and the holders
thereof shall, receive from the Company, for each share of Registrant Common
Stock subject to such Registrant Stock Option, an amount, if any, in cash equal
to the difference between the Merger Consideration and the exercise price per
share of such Registrant Stock Option, which amount, shall be paid by the
Registrant at the time such option is cancelled.

      All outstanding warrants to purchase Registrant Common Stock shall,
following the Effective Time, be exercisable only for an amount of cash equal to
the Warrant Consideration (as defined below) and the holders of such warrants
shall be entitled to receive, upon surrender to the Paying Agent of the warrant
certificates for cancellation, cash in an amount, if any, equal to the Warrant
Consideration. The Registrant shall take all actions necessary to ensure that
following the Effective Time (i) the warrants shall represent only the right to
receive the Warrant Consideration in lieu of shares of Registrant Common-Stock
issuable upon exercise thereof, (ii) all warrant agreements and warrant
certificates shall be terminated and cancelled, and (iii) no party to any
warrant agreement or holder of a warrant certificate shall have the right to
acquire any capital stock of the Registrant, Parent, the Surviving Corporation
or any of their respective subsidiaries. As used herein "Warrant Consideration"
means an amount, if any, per warrant equal to the product of (i) the number of
shares of Registrant Common Stock issuable upon exercise of such warrant and
(ii) the difference between the Merger Consideration and the exercise price per
share of Registrant Common Stock, without interest, which amount shall be paid
from and after the Effective Time.

<PAGE>   3
      Notwithstanding any provisions of the Merger Agreement to the contrary,
any shares of Registrant Common Stock held by a holder who has exercised such
holder's dissenters' rights in accordance with the California General
Corporation Law ("CGCL") and who, as of the Effective Time, has not effectively
withdrawn or lost such dissenters' rights ("Dissenting Shares"), shall not be
converted into or represent a right to receive the Merger Consideration, but the
holder the Dissenting Shares shall only be entitled to such rights as one
granted by the CGCL. Notwithstanding the foregoing provisions, if any holder of
shares of Registrant Common Stock who demands dissenters' rights with respect
to such shares shall effectively withdraw or lose (through the failure to
perfect or otherwise) such holder's dissenters' rights under the CGCL, then, as
of the Effective Time or the occurrence of such event, such holder's shares
shall automatically be converted into and represent only the right to receive
the Merger Consideration upon surrender of the applicable Certificate(s) as
provided in the Merger Agreement.

      The Purchaser obtained the funds required to purchase the shares of
Registrant Common Stock through advances made directly by the Parent. The Parent
obtained such funds from its own working capital and from an unsecured line of
credit (the "Credit Agreement") received from Interbanca S.p.A. The Credit
Agreement provides for a total amount of Lit. 15 billion (approximately $8.1
million). The interest rate is the EURIBOR six months interest rate plus 0.75%.
Interest payments are due every six months. The term of the Credit Agreement
expires on September 30, 2004. Payments of principal are Lit. 1.5 billion
(approximately $780,000) every six months. The aggregate amount drawn down by
the Parent under the Credit Agreement to fund the purchase of the shares of
Registrant Common Stock by the Purchaser pursuant to the Merger Agreement and
to pay related transaction expenses is Lit. 5 billion (approximately $2.7
million). The remaining portion of the purchase price for the shares of
Registrant Common Stock, including fees and expenses for the transaction
(approximately Lit. 6.65 billion or $3.5 million), will be paid from Targetti's
existing working capital.

      Pursuant to the terms of that certain Employment Agreement, dated as of
November 30, 1999 by and between Terrence Walsh and the Surviving Corporation,
Terrence Walsh will receive shares of common stock of the Surviving Corporation
equal to a 7.5%. ownership interest.

      As a result of the Merger, the transfer books of the Registrant were
closed as of the Effective Time and trading in the shares of Registrant Common
Stock on The NASDAQ Stock Exchange (the "NASDAQ") was suspended by the NASDAQ
prior to the opening of the market on December 1, 1999.

      (b) There are no arrangements known to the Registrant, including any
pledge by any person of securities of the Registrant, the operation of which may
at a subsequent date result in a change in control of the Registrant.

         WHEREAS, the Boards of Directors of Parent, Newco and the Company have
each determined that it is advisable and in the best interests of their
respective stockholders to consummate, and have approved, the business
combination transaction provided for herein in which Newco would merge with and
into the Company and the Company would become a wholly-owned subsidiary of
Parent (the "Merger"); and

         WHEREAS, concurrently herewith Parent has entered into voting

the Merger.

         NOW, THEREFORE, in consideration of the mutual representations,
warranties, covenants, agreements and conditions contained herein, and in order
to set forth the terms and conditions of the Merger and the mode of carrying the
same into effect, the Parties hereby agree as follows:

                                   ARTICLE I

                                   THE MERGER

SECTION 1.1       THE MERGER.

         Subject to the terms and conditions of this Agreement, at the Effective
Time, as defined below, in accordance with this Agreement and the California
General Corporation Law (the "CGCL"), Newco shall be merged with and into the
Company. Effective upon the Merger, the separate existence of Newco (except as
it may be continued by operation of law) shall cease, and the Company shall
continue as the surviving corporation (the "Surviving Corporation").

SECTION 1.2.      EFFECT OF THE MERGER.

         Upon the effectiveness of the Merger, the Surviving Corporation shall
succeed to and assume all the rights and obligations of the Company and Newco in
accordance with the CGCL, and the Merger shall otherwise have the effects set
forth in Section 1107 of the CGCL.

SECTION 1.3.      CONSUMMATION OF THE MERGER.

         The closing (the "Closing") of the Merger will take place as soon as
practicable after the satisfaction or waiver of the conditions to the
obligations of the parties to effect the Merger set forth

<PAGE>   6
herein, provided that this Agreement has not been terminated previously, at the
offices of Rogers & Wells LLP, 200 Park Avenue, New York, New York, or such
other location as the Parties may agree. On the date of the Closing (the
"Closing Date"), the Parties will cause the Merger to be consummated by filing
with the Secretary of State of the State of California a properly executed
agreement of merger in accordance with the CGCL which shall be effective upon
filing or on such later date as may be specified therein (the time of such
effectiveness being the "Effective Time").

SECTION 1.4.      ARTICLES OF INCORPORATION; BYLAWS; DIRECTORS AND OFFICERS.

         The Articles of Incorporation of Newco in effect at the Effective Time
shall be the Articles of Incorporation of the Surviving Corporation, until
thereafter amended in accordance with the provisions thereof and as provided by
the CGCL. The Bylaws of Newco in effect at the Effective Time shall be the
Bylaws of the Surviving Corporation, until thereafter amended in accordance with
the provisions thereof and the Articles of Incorporation of the Surviving
Corporation and as provided by the CGCL. From and after the Effective Time and
until their respective successors are duly elected or appointed and qualified,
(a) the persons listed on Schedule 1.4(a) shall be the directors of the
Surviving Corporation and (b) the persons listed on Schedule 1.4(b) shall be the
officers of the Surviving Corporation.

SECTION 1.5.      EFFECT ON SECURITIES.

         At the Effective Time, by virtue of the Merger and without any action
on the part of the holder thereof:

     (a)  Capital Stock of Newco. Each issued and outstanding share of common
stock, par value $0.001 per share, of Newco ("Newco Common Stock") shall be
converted into and become one fully paid and nonassessable share of common
stock, par value $0.001 per share, of the Surviving Corporation ("Surviving
Corporation Common Stock"). Each certificate representing outstanding shares of
Newco Common Stock shall at the Effective Time represent an equal number of
shares of Surviving Corporation Common Stock.

     (b)  Cancellation of Treasury Stock and Stock Owned by Parent and
Subsidiaries. All shares of common stock, par value $0.001 per share, of the
Company ("Company Common Stock") that are owned by the Company as treasury stock
and any shares of Company Common Stock owned by any Subsidiary of the Company,
Parent, Newco or any other wholly-owned Subsidiary of Parent shall be canceled
and retired and shall cease to exist and no stock of Parent or other
consideration shall be delivered in exchange therefor.

     (c)  Exchange Ratio for Company Common Stock. Each issued and outstanding
share of Company Common Stock (other than shares to be canceled in accordance
with Section 1.5(b) and other than Dissenting Shares) shall be converted into
the right to receive Four Dollars and Fifty Cents ($4.50) in cash (the "Merger
Consideration"). All such shares of Company Common Stock shall no longer be
outstanding and shall automatically be canceled and retired and shall cease to
exist, and each holder of a certificate representing any such shares shall cease
to have any rights with respect thereto, except the right to receive the Merger
Consideration, upon the surrender of such certificate in accordance with Section
1.7, without interest.

SECTION 1.6.      COMPANY STOCK PLANS; WARRANTS.

     (a)  All outstanding Company Stock Options, whether or not then vested or
exercisable, shall be made fully vested and exercisable and canceled by the
Company immediately before the Effective Time, and thereafter, the holders' sole
right shall be to, and the holders thereof shall, receive from the


<PAGE>   7
Company, for each share of Company Common Stock subject to such Company Stock
Option, an amount, if any, in cash equal to the difference between the Merger
Consideration and the exercise price per share of such Company Stock Option,
which amount, shall be paid by the Company at the time such option is canceled.
The Company will use its reasonable commercial efforts to obtain any necessary
consents and make any amendments to the terms of the Option Plans to the extent
such consents or amendments are necessary to give effect to the foregoing. All
applicable withholding taxes attributable to the payments made hereunder shall
be deducted from the amounts payable under this Section 1.6(a).

     (b) All outstanding warrants to purchase Company Common Stock shall,
following the Effective Time, be exercisable only for an amount of cash equal to
the Warrant Consideration and the holders of such warrants shall be entitled to
receive, upon surrender to the Paying Agent of the warrant certificates for
cancellation, cash in an amount, if any, equal to the Warrant Consideration. The
Company shall take all actions necessary to ensure that following the Effective
Time (i) the warrants shall represent only the right to receive the Warrant
Consideration in lieu of shares of Company Common Stock issuable upon exercise
thereof, (ii) all warrant agreements and warrant certificates shall be
terminated and cancelled, and (iii) no party to any warrant agreement or holder
of a warrant certificate shall have the right to acquire any capital stock of
the Company, Parent, the Surviving Corporation or any of their respective
Subsidiaries. As used herein "Warrant Consideration" means an amount, if any,
per warrant equal to the product of (i) the number of shares of Company Common
Stock issuable upon exercise of such warrant and (ii) the difference between the
Merger Consideration and the exercise price per share of Company Common Stock,
without interest, which amount shall be paid from and after the Effective Time.

SECTION 1.7.      PAYMENT FOR SHARES.

     (a) Paying Agent. Prior to the Effective Time, Parent shall designate a
bank or trust company to act as paying agent (the "Paying Agent") for the
purpose of exchanging certificates representing issued and outstanding shares of
Company Common Stock and warrants (each, a "Certificate") for the Merger
Consideration or the Warrant Consideration, as the case may be. Parent or Newco
shall, from time to time, make available or cause to be made available to the
Paying Agent funds in such amounts and at times necessary for the payment of the
Merger Consideration and the Warrant Consideration, in the manner provided
herein. The Paying Agent shall invest portions of the Merger Consideration and
the Warrant Consideration, as Parent directs (it being understood that any and
all interest earned on funds made available to the Paying Agent pursuant to this
Agreement shall be the property of, and shall be turned over to, Parent),
provided that such investments shall be in obligations of or guaranteed by the
United States of America or of any agency thereof and backed by the full faith
and credit of the United States of America, in commercial paper obligations
rated A-1 or P-1 or better by Moody's Investors Services, Inc. or Standard &
Poor's Corporation, respectively, or in deposit accounts, certificates of
deposit or banker's acceptances of, repurchase or reverse repurchase agreements
with, or Eurodollar time deposits purchased from, commercial banks with capital,
surplus and undivided profits aggregating in excess of US$100 million (based on
the most recent financial statements of such bank which are then publicly
available at the Securities and Exchange Commission (the "SEC") or otherwise).

     (b) Letter of Transmittal. Promptly after the Effective Time, the Surviving
Corporation shall instruct the Paying Agent to mail to each holder of record of
one or more shares of Company Common Stock or warrant certificates, (i) a letter
of transmittal, which shall specify that delivery shall be effected, and risk of
loss and title to the Certificates shall pass, only upon proper delivery of the
Certificates to the Paying Agent, and which shall have such other provisions as
Parent shall specify, and (ii) instructions for use in effecting the surrender
of the Certificates in exchange for the Merger Consideration or the Warrant
Consideration, as the case may be.


<PAGE>   8
     (c) Entitlement of Shares. Upon surrender of a Certificate for cancellation
to the Paying Agent, together with such letter of transmittal, duly executed and
completed in accordance with the instructions thereto, and such other documents
as may reasonably be required by the Paying Agent, the holder of such
Certificate shall be entitled to receive in exchange therefor the Merger
Consideration or the Warrant Consideration, as the case may be, payable in
respect of shares of Company Common Stock or warrants previously represented by
such Certificates, after giving effect to any withholding tax required by
Applicable Law, and the Certificates so surrendered shall forthwith be canceled.
Until surrendered as contemplated by this Section 1.7, each Certificate shall be
deemed at any time after the Effective Time to represent only the right to
receive the Merger Consideration or the Warrant Consideration, as the case may
be. No interest will be paid or accrued on the Merger Consideration or Warrant
Consideration.

     (d) Payments to Other Persons. If Merger Consideration or Warrant
Consideration is to be paid to any person other than the person in whose name
the Certificates for shares of Company Common Stock or warrants surrendered for
conversion are registered, it shall be a condition of the payment that such
Certificates be properly endorsed and the signatures thereon properly guaranteed
and otherwise in proper form for transfer and that the person requesting such
payment shall have paid to the Paying Agent any transfer or other taxes required
by reason of the delivery of Merger Consideration or Warrant Consideration to a
person other than the registered holder of such Certificate, or shall have
established to the satisfaction of the Surviving Corporation that such tax has
been paid or is not applicable.

     (e) Termination. Any portion of the exchange funds held by the Paying Agent
for delivery pursuant to this Section 1.7 and unclaimed at the end of six months
after the Effective Time shall be paid or delivered to the Surviving
Corporation, upon demand, and any holders of Certificates who have not
theretofore complied with this Section 1.7 shall, subject to Applicable Law,
thereafter look only to the Surviving Corporation for payment of the Merger
Consideration or the Warrant Consideration, as the case may be, in respect of
shares of Company Common Stock or warrants. Notwithstanding the foregoing, none
of Parent, the Surviving Corporation or the Paying Agent shall be liable to any
holder of shares of Company Common Stock or warrants for any amount paid to any
Governmental Authority pursuant to any applicable abandoned property, escheat or
similar law. Any amounts unclaimed by holders of shares of Company Common Stock
or warrants two years after the Effective Time (or such earlier date immediately
prior to such time as such amounts would otherwise escheat to or become the
property of any Governmental Authority) shall, to the extent permitted by
Applicable Law, become the property of the Surviving Corporation free and clear
of any claims or interest of any person previously entitled thereto.

     (f) Stock Transfer Books; No Further Ownership Rights. At and after the
Effective Time, the stock transfer books of the Company shall be closed, and
there shall be no further registrations of transfers of shares of Company Common
Stock thereafter on the records of the Company. From and after the Effective
Time, the holders of Certificates evidencing ownership of shares of Company
Common Stock issued and outstanding immediately prior to the Effective Time
shall cease to have any rights with respect to such shares, except as otherwise
provided for herein or by Applicable Law. If, after the Effective Time,
Certificates representing shares of Company Common Stock are presented to the
Surviving Corporation, Parent or the Paying Agent for any reason, they shall be
canceled and exchanged for the Merger Consideration as provided in this Section
1.7.

SECTION 1.8.      DISSENTING SHARES.

     (a) Notwithstanding any provisions of this Agreement to the contrary, any
shares of Company Common Stock held by a holder who has exercised such holder's
dissenters' rights in accordance with the CGCL and who, as of the Effective
Time, has not effectively withdrawn or lost such dissenters' rights ("Dissenting
Shares"), shall not be converted into or represent a right to receive the


<PAGE>   9
Merger Consideration, but the holder of the Dissenting Shares shall only be
entitled to such rights as are granted by the CGCL.

     (b) Notwithstanding the provisions of subsection (a) above, if any holder
of shares of Company Common Stock who demands dissenters' rights with respect to
such shares shall effectively withdraw or lose (through the failure to perfect
or otherwise) such holder's dissenters' rights under the CGCL, then, as of the
Effective Time or the occurrence of such event, such holder's shares shall
automatically be converted into and represent only the right to receive the
Merger Consideration upon surrender of the applicable Certificate(s) as provided
herein.

     (c) The Company shall give Parent (i) prompt written notice of any written
demands for payment with respect to any shares of Company Common Stock pursuant
to dissenters' rights, and any withdrawals of such demands or losses of such
rights, and any other instruments served pursuant to the CGCL, and (ii) the
opportunity to participate in all negotiations and proceedings with respect to
demands for dissenters' rights. The Company shall not, except with the prior
written consent of Parent, voluntarily make any payment with respect to demands
for dissenters' rights or offer to settle or settle any such demands.

SECTION 1.9.       SUBSEQUENT ACTIONS.

         If, at any time after the Effective Time, the Surviving Corporation
shall consider or be advised that any deeds, bills of sale, assignments,
assurances or any other actions or things are necessary or desirable to vest,
perfect or confirm of record or otherwise in the Surviving Corporation its
right, title or interest in, to or under any of the rights, properties or assets
of either of the Constituent Corporations acquired or to be acquired by the
Surviving Corporation as a result of, or in connection with, the Merger or
otherwise to carry out this Agreement, the officers and directors of the
Surviving Corporation are hereby authorized to execute and deliver, in the name
and on behalf of each of the Constituent Corporations or otherwise, all such
deeds, bills of sale, assignments and assurances and to take and do, in the name
and on behalf of each of the Constituent Corporations or otherwise, all such
other actions and things as may be necessary or desirable to vest, perfect or
confirm any and all right, title and interest in, to and under such rights,
properties or assets in the Surviving Corporation or otherwise to carry out this
Agreement.

                                   ARTICLE II

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

         The Company represents and warrants to Parent and Newco that, except as

Company to Parent:

SECTION 2.1.      ORGANIZATION AND QUALIFICATION.

         Each of the Company and its Subsidiaries is a corporation duly
organized, validly existing and in good standing under the laws of its
jurisdiction of organization and has the requisite corporate power and authority
to own, lease and operate the properties it purports to own and to carry on its
business as it is now being conducted. Each of the Company and its Subsidiaries
is duly qualified as a foreign corporation to do business and is in good
standing in each jurisdiction in which the character of the properties owned,
leased or operated by it or the nature of its activities makes such
qualification necessary, except where the failure to be so qualified or in good
standing, individually or in the aggregate, is not reasonably expected to have a
Material Adverse Effect.


<PAGE>   10
SECTION 2.2.      CHARTER DOCUMENTS.

         The Company has heretofore furnished to Parent a complete and correct
copy of the Company's Articles of Incorporation and Bylaws documents as in
effect on the date hereof. Each such charter document is in full force and
effect. The Company is not in violation of its charter documents.

SECTION 2.3.      CAPITALIZATION.

         The authorized capital stock of the Company consists of 10,000,000

Plans, shall be duly authorized, validly issued, fully paid and nonassessable.
There are no obligations, contingent or otherwise, of the Company or of any
Subsidiary to repurchase, redeem or otherwise acquire any shares of Company
Common Stock or the shares of any Subsidiary or to provide funds to or make any
investment (in the form of a loan, capital contribution or otherwise) in any
Subsidiary or any other entity. None of the Company Stock Options, warrants,
rights, agreements, arrangements or commitments identified in Section 2.3 or

in Section 2.3 of the Company Disclosure Schedule, all of the outstanding shares
of each Subsidiary (and all shares to be issued prior to the Effective Time) are
duly authorized, validly issued, fully paid and nonassessable, and all such
shares are owned by the Company free and clear of all security interests, liens,
claims, pledges, agreements, limitations in the Company's voting rights, charges
or other encumbrances of any nature whatsoever (collectively, "Liens").

SECTION 2.4.      AUTHORITY; BOARD APPROVAL.

(a) The Company has full corporate power and authority to enter into this
Agreement and, subject to obtaining the Company Stockholders' Approval, to
perform its obligations hereunder and to consummate the transactions
contemplated hereby. This Agreement has been duly and validly executed and
delivered by the Company and, subject to the obtaining of the Company
Stockholders' Approval constitutes a legal, valid and binding obligation of the

Schedule, (i) the Company has not breached, is not in default under and has not
received written notice of any breach of or default under any Material Contract,
except for any such breach or default which is not reasonably expected to have a

party to any of the Material Contracts has breached or is in default of any of
its obligations thereunder, except for any such breach or default which is not
reasonably expected to have a Material Adverse Effect and (iii) each of the
Material Contracts is in full force and effect.

in any breach of or constitute a default (or an event that with notice or lapse
of time or both would become a default) under, or impair the Company's rights or
alter the rights or obligations of any third party under, or give to others any
rights of termination, amendment, acceleration or cancellation of, any Material
Contract, or result in the creation of a lien or encumbrance on any of the
properties or assets of the Company or any Subsidiary.

     (d) The execution and delivery of this Agreement by the Company does not,
and the performance of this Agreement by the Company will not, require the

and each Subsidiary are in compliance with the terms of the Company Permits.

     (b) Except as set forth in Section 2.6 of the Company Disclosure Schedule,
the Company and each Subsidiary are not in conflict with, or in default or
violation of any Applicable Law relating to the Company or any Subsidiary, or by

then on the date of such filing) contain any untrue statement of a material fact
or omit to state a material fact required to be stated therein or necessary in
order to make the statements therein, in the light of the circumstances under
which they were made, not misleading. No Subsidiary is required to file any
forms, reports or other documents with the SEC.

     (b) Each of the consolidated financial statements (including, in each case,
any related notes thereto) contained in the SEC Reports was prepared in
accordance with generally accepted accounting principles ("GAAP") applied on a
consistent basis throughout the periods involved (except as may be indicated in

Company or any of its Subsidiaries to any other person, with respect to the
existence or contents of this Agreement, except for such public disclosure as
may be necessary, following consultation with legal counsel, for the party
proposing to make the disclosure not to be in violation of or default under any
Applicable Law, regulation or governmental order. If either party proposes to

for such disclosure and provide such party with the text of the proposed
disclosure, as far in advance of its disclosure as is practicable, and will in
good faith consult with and consider the suggestions of the other party
concerning the nature and scope of the information it proposes to disclose.
Attached as Exhibit B hereto is a form of the press release that the Parties

                  NOW, THEREFORE, in consideration of the foregoing premises and
the mutual covenants and agreements contained herein, the parties hereto agree

                           (a)      The Shareholders hereby agree that during

                  however called, or in connection with any written consent of
                  the holders of Common Stock, the Shareholders shall vote (or
                  cause to be voted) all shares of Common Stock held of record
                  or Beneficially Owned by the Shareholders, whether heretofore
                  owned or hereafter acquired (collectively, the "Shares"), (i)

                  by the Company and the approval of the terms thereof, and each
                  of the other transactions and actions contemplated by the
                  Merger Agreement (and the matters related to the consummation
                  thereof) and any actions required in furtherance thereof; and
                  (ii) against any action or agreement that would result in a

                  be required by this Agreement to exercise options for Shares
                  if the exercise price per Share pursuant to such option would

of the foregoing.

                  4.3      Conduct of Shareholder. The Shareholders will not (i)
take, agree or commit to take any action that would make any representation and

                  4.4      Employment Agreement. Upon the closing of the Merger

                  4.5      Update of SEC Filings. The Shareholders will update
all filings made by them with the Securities and Exchange Commission (the "SEC")
and file all documents required to be filed with the SEC in compliance with the
Exchange Act as are necessary to consummate the transactions contemplated by
this Agreement.

                  4.6      Disclosure. Without the prior written consent of the
other, neither Parent nor the Shareholders will, and Parent and the Shareholders
shall cause their respective representatives not to, make any release to the
press or other public disclosure, or make any statement to any employee (other
than those officers of the Company whose involvement in the merger is required
in order to consummate the transaction), competitor, customer, client or
supplier of the Company or any of its subsidiaries to any other person with
respect to the existence or contents of this Agreement, except for such public
disclosure as may be necessary, following consultation with legal counsel, for
the party proposing to make the disclosure not to be in violation of or default
under any applicable law, regulation or governmental order. If either party
proposes to make such disclosure, that party will discuss with the other party
its rationale for such disclosure and provide such party with the text of this
proposed disclosure, as far in advance of its disclosure as is practicable, and
will in good faith consult with and consider the suggestions of the other party
concerning the nature and scope of the information it proposes to disclose.
Notwithstanding the foregoing, the Shareholders hereby permit their identity and
ownership of the Shares and the nature of the commitments, arrangements and
understandings under this Agreement to be disclosed by the Company in its Proxy
Statement (and all related documents) relating to the Merger.

1.2 of this Agreement, this Agreement shall terminate (a) in the event the
Merger Agreement is terminated in accordance with its terms upon such
termination, and (b) in the event the Merger is consummated, upon the Effective
Time; provided, however, that no such termination shall relieve any party of
liability for a breach hereof prior to termination.

                  5.2      Specific Performance. The parties hereto agree that
the Parent may be irreparably damaged if for any reason the Shareholders failed
to perform any of their other obligations under this Agreement, and that the
Parent would not have an adequate remedy at law for money damages in such event.
Accordingly, the Parent shall be entitled to specific performance and injunctive
and other equitable relief to enforce the performance of this Agreement by the
Shareholders. This provision is without prejudice to any other rights that the
Parent may have against Shareholders for any failure to perform its obligations
under this Agreement.

given pursuant to this Agreement must be in writing and delivered personally, by

United States District Court for the Central District of California in any such

such consent to jurisdiction is solely for the purpose referred to in this
Section 5.7 and shall not be deemed to be a general submission to the
jurisdiction of said courts or in the State of California other than for such
purpose. Nothing herein shall affect the right of any party to serve process in
any other manner permitted by law or to commence legal proceedings or otherwise
proceed against the other in any other jurisdiction. The parties hereby

construed and interpreted in accordance with the substantive laws of the State
of California, without giving effect to any conflicts of law rule or principle

agree that this Agreement was negotiated fairly between them at arm's length and
that the final terms of this Agreement are the product of the parties'

legal counsel of its own choosing with regard to the contents of this Agreement

such consent to jurisdiction is solely for the purpose referred to in this

jurisdiction of said courts or in the State of California other than for such
purpose. Nothing herein shall affect the right of any party to serve process in
any other manner permitted by law or to commence legal proceedings or otherwise
proceed against the other in any other jurisdiction. The parties hereby

                                                                MERGER AGREEMENT


                              FORM OF PRESS RELEASE


         Santa Ana, California - September __, 1999 - In a joint announcement
Monday, Tivoli Industries Inc. (Nasdaq:TVLI) and Targetti Sankey S.p.A., an
Italian Company ("Targetti" - Milan Exchange: TS) announced that they had
entered into a merger agreement, in which Tivoli will become a wholly owned
subsidiary of Targetti.

         Each Tivoli stockholder will receive a cash payment of $4.50 per share
of common stock of Tivoli, representing total proceeds to the shareholders of
Tivoli of approximately $5.6 million.

         Tivoli said that a proxy statement describing the merger and calling a
special meeting of its stockholders to approve the merger, is expected to be
mailed to the stockholders subsequent to the review of the proxy statement by
the Securities and Exchange Commission.

         The special meeting of the stockholders is expected to be held
approximately 20 business days subsequent to the mailing of the proxy statement
and, if the merger is approved by the stockholders, it is expected to be closed
shortly after the special meeting.

         Tivoli directors and officers who own approximately 36 percent of
Tivoli's outstanding common stock, have agreed to vote in favor of the merger.
Additionally, Tivoli has agreed, under certain circumstances, to pay a breakup
fee in the event that the Merger Agreement is terminated.

         An independent committee of Tivoli's board of directors has recommended
that the stockholders vote in favor of the merger. L.H. Friend, Weinress,
Frankson & Presson LLC, Tivoli's independent financial adviser, has rendered its
opinion to the board of directors that the cash payment of $4.50 per share of
common stock is fair to the stockholders of Tivoli from a financial point of
view.

         Completion of the merger is subject to certain conditions, including
the approval of the merger by at least 51 percent of the stockholders of Tivoli
and the receipt of all required regulatory approvals. The merger will be
financed by Targetti from its existing resources and available lines of credit.

         In an announcement in Florence, Paolo Targetti, president of Targetti
Sankey S.p.A., said: "Targetti is pleased abut this merger with Tivoli because
it emphasizes our strong commitment to continueD growth within the U.S. and
North America markets. Our relationship with Tivoli through our joint venture -
Targetti USA, has established a successfully framework and foundation upon which
to continue our marketing and sales efforts."

         Targetti continued: "The two companies have complemented each other
from a product, market, cultural and organizational perspective. TIVOLI'S
reputation as a high-end specialty lighting supplier provides expanded
opportunities to increase exports from the U.S. to Europe, the Pacific Rim and
South America."
<PAGE>   98
         Targetti also announced that Terrence C. Walsh, chairman and chief
executive officer of Tivoli Industries, will remain with the new firm as vice
chairman and CEO. Charles F. Kimmel, currently Tivoli's president, will retain
this position in the new organization.

         Commenting further on the retention of the key executives, Targetti
continued: "We are very happy to build upon the vision and teamwork that
Terrence Walsh has established in the company. Both Mr. Walsh and Mr. Kimmel
will provide the leadership and continuity of our efforts to expand Targetti's
importance in the U.S. lighting market."

         Concurrently, in Santa Ana, Terrence C. Walsh said: "On behalf of the
board of directors, employees and shareholders of Tivoli, I am pleased to
announce the merger with Targetti. We look upon this merger as an evolutionary
step for Tivoli, building upon a strong relationship with Targetti that began
over five years ago.

         "The Tivoli team is very excited about our further expansion and
growth, based here in Santa Ana. The combination of Tivoli's products and
markets with Targetti's global strengths and resources makes this a strong
strategic move that will enhance our products and services to our customers.
Both Chuck Kimmel and I are excited about joining Targetti's team."

         Targetti was founded in 1928 and, together with its subsidiaries and
associated companies, is one of the principal manufacturers in the
technical/architectural lighting sectors in both Italy and Europe. In 1998,
Targetti successfully completed an initial public offering and is listed on the
Milan Exchange.

         Targetti develops, manufactures and distributes interior, exterior and
decorative lighting products for both commercial and residential users. Targetti
has developed an extensive international support network that provides for an
operating and distribution structure with comprehensive support through its
principal markets worldwide.

         This news release contains certain forward-looking statements that
involve risks and uncertainties, including statements regarding future operating
activities, integration issues and other matters. Actual results may vary
materially, including for the reasons and based upon the Risk Factors described
in Tivoli's filings and reports with the Securities and Exchange Commission.
None of the parties accepts any obligation to update any such forward-looking
statements.

the Company may terminate Executive's employment


                                       2
<PAGE>   101
hereunder should the period of such incapacity exceed six (6) consecutive
months. Any such termination shall not be considered to be for "Cause" as
defined in subparagraph (e) immediately below.

                  (c) Executive's employment hereunder may be terminated by the
Company prior to the expiration of the Term with or without "Cause" (as defined
in subparagraph 6(e) below), immediately upon delivery by the Company of a
written Notice of Termination.

                  (d) In the event that Executive is terminated without Cause,
the Company shall pay Executive's salary through the date of termination, after
deducting any amounts lawfully owing from Executive to the Company, plus an

determined in accordance with Section 3(a). The Company shall also pay, when
due, the Executive's C.O.B.R.A. health insurance expenses for the period
commencing on the date of termination and ending on the earlier of (i) the
Executive obtaining new employment which provides the Executive with health
insurance coverage or (ii) eighteen months after the date of the Executive's
termination hereunder. Upon payment of the foregoing amounts to the Executive,
the Company shall thereafter have no further obligation to Executive.

                  (e) For the purposes of this Agreement, "Cause" means (i) the
willful and continued failure by Executive to substantially perform Executive's
duties hereunder, other than any such failure resulting form Executive's
incapacity due to physical or mental illness, after a demand for substantial
performance is delivered to Executive by the Board which specifically identifies
the manner in which the Board believes that Executive has not substantially
performed such duties, (ii) the intentional engaging by Executive in conduct
materially and demonstrably injurious to the Company, or (iii) conviction of a
felony. For purposes of this subparagraph, no act, or failure to act, on the
part of the Executive shall be considered "intentional" merely because it was
the result of bad judgment or negligence; rather such act or failure or failure
to act must have been done or omitted to have been done, by Executive other than
in good faith and without reasonable belief that Executive's action or omission
was in the best interests of the Company. Notwithstanding the foregoing,
Executive's employment shall not be deemed to have been terminated for "Cause"
pursuant to clauses (i) or (ii) above unless and until there shall have been
delivered to Executive a copy of a resolution duly adopted by the affirmative
vote of the Board at a meeting of the Board called and held for such purpose
(after reasonable notice to Executive and an opportunity for Executive, together
with Executive's counsel, to be heard before the Board), finding that in the
good faith opinion of the Board, Executive was guilty of conduct described above
in clauses (i) or (ii) of this subparagraph and specifying the particulars
thereof in detail. In the event that Executive is terminated for Cause, the
Company shall pay Executive's salary through date of termination after deducting
any amounts lawfully owing from Executive to the Company, and shall thereafter
have no further obligations to Executive except as may be provided in the
Shareholders Agreement with respect to the repurchase of the Shares.

                  (f) Executive shall be entitled to terminate his employment
with the Company hereunder for "Good Reason." If the Executive terminates his
employment hereunder for Good Reason, the Company shall pay Executive's salary
through the date of termination, after deducting any amounts lawfully owing from
Executive to the Company, plus the Severance Amount. Upon payment of such
amounts, the Company shall thereafter have no further obligation to Executive
except as may be provided in the Shareholders Agreement with respect to the
repurchase of the Shares. For purposes of this Agreement, any termination of
employment under any one or more of the following circumstances shall be for
"Good Reason":



                                       3
<PAGE>   102
                           (i) Without Executive's express written consent, the
repeated assignment to Executive of any duties inconsistent with Executive's
positions, duties, responsibilities and status with the Company, or a reduction
in Executive's reporting responsibilities, titles or offices as in effect upon
the execution hereof, or any removal of Executive from or any failure to reelect
Executive to any such positions, except in connection with the termination of
Executive's employment for Cause, disability, retirement or as a result of
death;

                           (ii) If the Company or the Parent experiences a
change of control via merger, consolidation, sales of all or substantially all
the shares or the assets or other transaction (or series of related
transactions) following which the shareholders of the Company or the Parent
immediately prior to such transaction own less than 50% of the outstanding
voting shares of the Company or the Parent following such transaction;

                           (iii) The reduction by the Company in Executive's
base salary, as the same may be thereafter increased from time to time, or the
failure by the Company to otherwise pay Executive the base salary provided for
herein;

                           (iv) The failure by the Company to continue
Executive's participation in any benefit plan, pension plan, qualified
retirement plan, life insurance plan, vacation plan, holiday plan, car lease
plan, medical expense, health and accident plan or disability plan, or expense
reimbursement arrangement specified in paragraph 4 and 5 hereof (or a similar
plan or arrangement adopted by the Company for its executives), or the taking of
any action by the Company (prompt notice of which shall be provided to
Executive) which would materially adversely affect Executive's participation in
(including materially increasing Executive's costs of such participation), or
materially reduce Executive's benefits under, any of such plans, or which would
deprive Executive of any other material fringe or personal benefits under any of
such plans;

                           (v) Any action by the Company that would require
Executive to relocate his principal residence or office to a location more than
50 miles from the Company's current principal executive offices; and

                           (vi) Any action intended as its primary purpose to
reduce the amount of any payment due to the Executive under Sections 2.02(a) or
2.03(a) of the Shareholders Agreement;

in each case after the Executive has given the Company and the Parent written
notice of any action that the Executive believes constitutes Good Reason under
any of the clauses set forth above and the Company has failed within 60 days
after its receipt of such notice to correct or rescind such action. Any failure
by the Executive to give notice that the taking of any action by the Company
constitutes Good Reason within 60 days after the date of the occurrence of such
action shall be deemed to be a waiver and consent by the Executive to the taking
of such action by the Company and shall not thereafter give rise to Good Reason
hereunder.

                  (g) Any termination of Executive's employment by the Company,
or by Executive for Good Reason shall be communicated by Written Notice of
Termination to the other party hereto. For purposes of this Agreement, a "Notice
of Termination" shall mean a notice which shall indicate the specific
termination provisions in this Agreement relied upon, shall set forth in
reasonable detail the facts and circumstances claimed to provide a basis for


                                       4
<PAGE>   103
termination of Executive's employment under the provision so indicated, and

continuance of this Agreement or after its expiration or earlier termination,
whether by Executive or by the Company, in any manner or form, directly or
indirectly, use, disclose, duplicate, license, sell, reveal, divulge, publish or

                                                                MERGER AGREEMENT


                              EMPLOYMENT AGREEMENT

         THIS EMPLOYMENT AGREEMENT (the "Agreement") is made and entered into as
of __________ __, 1999, by and between TIVOLI INDUSTRIES, INC., a California
corporation whose principal place of business is located in Santa Ana,
California 92705 (the "Company"), and CHARLES KIMMEL, an individual residing in
the State of California ("Executive").

         This Agreement is being executed simultaneously with the closing of the
merger (the "Merger") of Florence Acquisition Corp., a wholly owned subsidiary
of Targetti Sankey S.p.A., an Italian corporation ("Parent"), with and into the
Company pursuant to that certain Agreement and Plan of Merger dated as of
September 17, 1999, among Newco, Parent and the Company. In connection
therewith, the Executive, who has been employed by the Company prior to the
Merger, has agreed to become an executive of the Company as the surviving
corporation in the Merger.

         Accordingly, the parties agree as follows:

         1. Term. This Agreement shall continue in full force and effect for a
period which shall commence as of the date hereof and shall continue until
December 1, 2001 (the "Term"), unless sooner terminated as hereinafter provided.
This Agreement shall be automatically renewed for additional one year terms
unless either party delivers notice of termination (the "Termination Notice") to
the other party not later than 90 days prior to the scheduled expiration of the
then current Term. At any time after a Termination Notice has been delivered in
accordance with the preceding sentence, the Company shall have the option of
immediately terminating the Executive's employment hereunder by paying the
Executive in cash an amount equal to (A) the Executive's Annual Salary (as
hereinafter defined), divided by (B) 365, multiplied by (C) the number of days
from the date of termination of the Executive's employment until the expiration
of the then current Term.

         2. Employment. Executive shall serve as the President and Chief
Financial Officer of the Company, subject to the reasonable directions of the
Board of Directors of the Company (the "Board"), and as such shall have
day-to-day responsibility for the management of all of the Company's affairs and
operations. Executive shall devote his full executive time, energies and
abilities to the proper and efficient performance of his duties provided herein.
Executive shall at all times perform his duties and obligations faithfully and
diligently and to the best of Executive's ability.

         3. Compensation.

                  (a) The Company shall pay the Executive during the Term a
salary at the rate of One Hundred Thirty Three Thousand Three Hundred Fifty
Dollars ($133,350) per annum (the "Annual Salary"). The Annual Salary shall be
payable in equal semi-monthly installments, less such deductions as shall be
required to be withheld by applicable law and regulations. Executive's salary
shall be reviewed by the Board annually not later than November 1, of each year
and Executive shall receive such salary increases as the Board shall determine
in its sole discretion.
<PAGE>   108
                  (b) Executive also shall be eligible to receive a bonus as
provided by the Company's Key Executive Retention Program as set forth in
Section 4.7(a) of the above referenced Agreement and Plan of Merger.

                  (c) Executive also shall be eligible to receive a bonus as
provided in the Company's Management Incentive Plan for Fiscal Year Ending
September 30, 1999 and in any future incentive bonus plan hereafter adopted
instituted by the Company in its discretion.

                  (d) In addition to the above, Executive shall be entitled to
receive an auto allowance of $600 per month, payable monthly.

         4. Benefits and Vacations.

                  (a) Executive and his dependents shall be entitled to
participate in or receive benefits under the Company's health insurance plans or
arrangements as in effect on the date hereof for such period of time as such
plans and arrangements shall remain in effect. In addition, Executive shall be
entitled to participate in or receive benefits under any pension plan,
profit-sharing plan, life insurance, health-and-accident plan or arrangement
made available in the future by the Company to its executives and key management
executives, subject to and on a basis consistent with the terms, conditions and
overall administration of such plans and arrangements, for so long as such plans
and arrangements remain in effect. Nothing paid to Executive under any such plan
or arrangement presently in effect or made available in the future shall be
deemed to be in lieu of any compensation payable to Executive hereunder.

                  (b) Executive shall be entitled to the number of paid
vacations days in each calendar year and to compensation for earned but unused
vacation days, determined by the Board from time to time for its executives and
key management executives, but not less than four (4) weeks in each year of the
Term hereof. Executive shall also be entitled to all paid holidays given by the
Company to its executives and key management executives.

         5. Expenses. During the Term, Executive shall be entitled to receive
prompt reimbursement of all reasonable expenses incurred by Executive (in
accordance with the policies and procedures from time to time adopted by the
Board for its senior executive officers) in performing the services contemplated
hereunder, provided that Executive properly accounts therefore in accordance
with the Company's policy.

         6. Termination.

                  (a) Executive's employment hereunder shall terminate
immediately upon death.

                  (b) In the Event that Executive shall be unable to perform the
services contemplated hereunder by reason of disability, illness or other
incapacity, such failure to so perform such duties shall not be grounds for
terminating the employment of Executive by the Company, provided, however, that
the Company may terminate Executive's employment hereunder should the period of
such incapacity exceed six (6) consecutive months. Any such termination shall
not be considered to be for "Cause" as defined in subparagraph (e) below.

                  (c) Executive's employment hereunder may be terminated by the
Company prior to the expiration of the Term with or without "Cause" (as defined
in subparagraph 6(e) below), immediately upon delivery by the Company of a
written Notice of Termination.,



                                       2
<PAGE>   109
                  (d) In the event that Executive is terminated without Cause,
the Company shall pay Executive's salary through the date of termination, after
deducting any amounts lawfully owing from Executive to the Company, plus an
amount (the "Severance Amount") equal to two times the Annual Salary as
determined in accordance with Section 3(a). The Company shall also pay, when
due, the Executive's C.O.B.R.A. health insurance expenses for the period
commencing on the date of termination and ending on the earlier of (i) the
Executive obtaining new employment which provides the Executive with health
insurance coverage or (ii) eighteen months after the date of the Executive's
termination hereunder. Upon payment of the foregoing amounts to the Executive,
the Company shall thereafter have no further obligation to Executive.

                  (e) For the purposes of this Agreement, "Cause" means (i) the
willful and continued failure by Executive to substantially perform Executive's
duties hereunder, other than any such failure resulting form Executive's
incapacity due to physical or mental illness, after a demand for substantial
performance is delivered to Executive by the Board which specifically identifies
the manner in which the Board believes that Executive has not substantially
performed such duties, (ii) the intentional engaging by Executive in conduct
materially and demonstrably injurious to the Company, or (iii) conviction of a
felony. For purposes of this subparagraph, no act, or failure to act, on the
part of the Executive shall be considered "intentional" merely because it was
the result of bad judgment or negligence; rather such act or failure to act must
have been done or omitted to have been done, by Executive other than in good
faith and without reasonable belief that Executive's action or omission was in
the best interests of the Company. Notwithstanding the foregoing, Executive's
employment shall not be deemed to have been terminated for "Cause" pursuant to
clauses (i) and (ii) above unless and until there shall have been delivered to
Executive a copy of a resolution duly adopted by the affirmative vote of the
Board at a meeting of the Board called and held for such purpose (after
reasonable notice to Executive and an opportunity for Executive, together with
Executive's counsel, to be heard before the Board), finding that in the good
faith opinion of the Board, Executive was guilty of conduct described above in
clauses (i) or (ii) of this subparagraph and specifying the particulars thereof
in detail. In the event that Executive is terminated for Cause, the Company
shall pay Executive's salary through date of termination after deducting any
amounts lawfully owing from Executive to the Company, and shall thereafter have
no further obligations to Executive.

                  (f) Executive shall be entitled to terminate his employment
with the Company hereunder for "Good Reason." If the Executive terminates his
employment hereunder for Good Reason, the Company shall pay Executives salary
through the date of termination, after deducting any amounts lawfully owing from
the Executive to the Company, plus an amount equal the Severance Amount, and
shall thereafter have no further obligation to the Executive. For purposes of
this Agreement, any termination of employment under any one or more of the
following circumstances shall be for "Good Reason":

                           (i) Without Executive's express written consent, the
repeated assignment to Executive of any duties inconsistent with Executive's
positions, duties, responsibilities and status with the Company, or a reduction
in Executive's reporting responsibilities, titles or offices as in effect upon
the execution hereof, or any removal of Executive from or any failure to reelect
Executive to any such positions, except in connection with the termination of
Executive's employment for Cause, disability, retirement or as a result of
death;



                                       3
<PAGE>   110
                           (ii) If the Company or the Parent experiences a
change of control via merger, consolidation, sales of all or substantially all
the shares or the assets or other transaction (or series of related
transactions) following which the shareholders of the Company or the Parent
immediately prior to such transaction own less than 50% of the outstanding
voting shares of the Company or the Parent following such transaction.

                           (iii) The reduction by the Company in Executive's
base salary, as the same may be thereafter increased from time to time, or the
failure by the Company to otherwise pay Executive the base salary provided for
herein;

                           (iv) The failure by the Company to continue
Executive's participation in any benefit plan, pension plan, qualified
retirement plan, life insurance plan, vacation plan, holiday plan, car lease
plan, medical expense, health and accident plan or disability plan, or expense
reimbursement arrangement specified in paragraph 4 and 5 hereof (or a similar
plan or arrangement adopted by the Company for its executives), or the taking of
any action by the Company (prompt notice of which shall be provided to
Executive) which would materially adversely affect Executive's participation in
(including materially increasing Executive's costs of such participation), or
materially reduce Executive's benefits under, any of such plans, or which would
deprive Executive of any other material fringe or personal benefits under any of
such plans; and

                           (v) Any action by the Company that would require
Executive to relocate his principal residence or office to a location more than
50 miles from the Company's current principal executive offices;

in each case after the Executive has given the Company and the Parent written
notice of any action that the Executive believes constitutes Good Reason under
any of the clauses set forth above and the Company has failed within 60 days
after its receipt of such notice to correct or rescind such action. Any failure
by the Executive to give notice that the taking of any action by the Company
constitutes Good Reason within 60 days after the date of the occurrence of such
action shall be deemed to be a waiver and consent by the Executive to the taking
of such action by the Company and shall not thereafter give rise to Good Reason
hereunder.

                  (g) Any termination of Executive's employment by the Company
for disability, retirement or Cause, or by Executive for Good Reason shall be
communicated by Written Notice of Termination to the other party hereto. For
purposes of this Agreement, a "Notice of Termination" shall mean a notice which
shall indicate the specific termination provisions in this Agreement relied
upon, shall set forth in reasonable detail the facts and circumstances claimed
to provide a basis for termination of Executive's employment under the provision
so indicated, and shall set forth the date upon which such termination is to
become effective.

         7. Proprietary Information. Executive acknowledges that certain
technological and other information may from time to time be disclosed to
Executive by the Company during the continuance hereof. Executive hereby
acknowledges that all such information and technology, whether currently
existing or hereafter developed by the Company through or involving the services
and efforts of Executive hereunder, shall at all times consist of an be
preserved by Executive as valuable trade secrets and confidential information
which is proprietary to and owned exclusively by the Company, and that Executive
does not have, and shall not have or


                                       4
<PAGE>   111
hereafter acquire, any rights in or to any such information and technology,
including without limitation any patents, inventions, discoveries, know-how,
trademarks or tradenames used or adopted by the Company in connection with the
design, development, manufacture, marketing, sale or installation of any
products which at any time during the continuation hereof may be offered or sold
or licensed by the Company. Executive further warrants and agrees that he shall
not at any time, whether during the continuance of this Agreement or after its
expiration or earlier termination, whether by Executive or by the Company, in
any manner or form, directly or indirectly, use, disclose, duplicate, license,
sell, reveal, divulge, publish or communicate any portion of any such
information concerning the Company, or any customers or other products of the
Company, to any person, firm or entity.

         8. Agreement Not to Compete; Non-Solicitation

                  (a) Executive acknowledges that, by virtue of this position
with the Company, Executive will develop considerable expertise in the business
operations of the Company and will have access to extensive confidential
information with respect to the Company. Executive also acknowledges that this
is a personal services contract wherein Executive's services are of a special,
unique, unusual, extraordinary and intellectual character. Executive further
acknowledges that his services will have peculiar value, the loss of which
cannot be reasonably or adequately compensated in damages in an action at law.
Executive acknowledges that the Company would be irreparably damaged, and its
substantial investment materially impaired, if Executive were to enter into an
activity competing with the Company's business in violation of the terms of this
Agreement or if Executive were to make unauthorized use or disclosure of any
confidential information concerning the business of the Company.

                  (b) In consideration of the terms and conditions of this
Agreement, including without limitation, this Section 8 and payment of Severance
Amount, Executive hereby agrees that, during the period of his employment with
the Company and for the longer of (i) the remainder of the term of this
Agreement had Executive not been terminated, or (ii) a period of 24 months, he
will not without the Company's express written consent, (i) engage in any
employment or business activity which is competitive with, or would otherwise
conflict with, the business of the Company as is currently conducted or
presently under development as of the date of Executive's termination; or (ii)
solicit or attempt to solicit, either directly or through others, (A) any
executive, consultant, or independent contractor of the Company to terminate his
or her relationship with any other person or business entity; or (B) the
business of any customer, vendor, or distributor of the Company. Executive
further agrees to notify the Company, in writing, before Executive obtains
employment with, performs work for, or engages in any professional activity on
behalf of any company, person or entity in the lighting industry.

                  (c) In the event that Executive engages in any such
competitive activity in breach of this Agreement, Executive hereby agrees that
he shall return to the Company the Severance Amount in full immediately
following such breach and that the Company shall be entitled to equitable relief
(e.g. injunctions) to prevent any such competitive activity by Executive. The
right and remedies hereof shall be cumulative (and not alternative).

                  (d) Executive expressly acknowledges that he is voluntarily
entering into this Agreement, that the provisions in this Section 8 are a
material inducement to the Company in


                                       5
<PAGE>   112
entering this Agreement, and that the terms and conditions of this Agreement are
fair and reasonable to Executive in all respects.

         9. General Provisions.

                  (a) Any notice, request, demand or other communication
required or permitted hereunder shall be deemed to be properly given when
personally served in writing, when deposited in the United States mail, postage
prepaid, or when communicated to a public telegraph company for transmittal,

all of Executive's rights or duties hereunder without the prior written consent

respects in accordance with the laws of the State of California.

                  (d) Captions and Paragraph headings used herein are for
convenience only and are not a part of this Agreement and shall be used in
construing it.

                  (e) Should any provision of this Agreement for any reason be
declared invalid, void or unenforceable by a court of competent jurisdiction,
the validity and binding effect of any remaining portions shall not be affected,
and the remaining provisions of this Agreement shall remain in full force as if
this Agreement had been executed with said provision eliminated.

                  (f) The Company shall indemnify Executive to the fullest
extent permitted by applicable law with respect to any claims arising from the
performance by Executive of his duties hereunder during the Term of this
Agreement.

                  (g) This Agreement contains the entire agreement of the
parties, and supercedes any and all other agreements, either oral or in writing,

     1.  Guarantee of Signatures.  All signatures on this Letter of Transmittal
must be guaranteed by a firm which is a member in good standing of a recognized
Medallion Signature Guarantee Program, or by any other "eligible guarantor
institution," as such term is defined in Rule 17Ad-15 under the Securities
Exchange Act of 1934, as amended (each of the foregoing being referred to as an
"Eligible Institution"), unless (i) this Letter of Transmittal is signed by the
registered holder(s) of the Shares surrendered hereby and such holder(s) has
(have) completed neither the box entitled "Special Payment Instructions" nor the
box entitled "Special Delivery Instructions" on the reverse hereof or (ii) such
Shares are tendered for the account of an Eligible Institution. See Instruction
4.

     2.  Completion of Delivery of Letter of Transmittal and Stock
Certificates.  The Letter of Transmittal must be properly completed and signed
by the registered holders (or assignee(s) thereof) of the Shares being
surrendered herewith, and mailed, hand delivered or delivered by overnight
courier with the Share Certificates (and any other documents required by
Instruction 4) to the Paying Agent at one of the addresses set forth on the
front hereof. A return envelope is enclosed for your convenience.

     THE METHOD OF DELIVERY OF THIS LETTER OF TRANSMITTAL, SHARE CERTIFICATES
AND ALL OTHER REQUIRED DOCUMENTS IS AT THE OPTION AND RISK OF THE SHAREHOLDER,
AND THE DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE PAYING
AGENT. IF DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED,
PROPERLY INSURED, IS RECOMMENDED.

     3.  Inadequate Space.  If the space provided herein under "Description of
Shares Surrendered" is inadequate, the Share Certificate numbers and the number
of Shares evidenced by such Share Certificates should be listed on a separate
schedule and attached hereto.

     4.  Signatures on Letter of Transmittal; Stock Powers and Endorsements.  If
this Letter of Transmittal is signed by the registered holder(s) of the Shares
surrendered hereby, the signature(s) must correspond with the name(s) as written
on the face of the Share Certificates evidencing such Shares without alteration,
enlargement or any other change whatsoever.

     If any of the Shares surrendered hereby are owned of record by two or more
persons, all such persons must sign this Letter of Transmittal.

     If any of the Shares surrendered hereby are registered in the names of
different holders, it will be necessary to complete, sign and submit as many
separate Letters of Transmittal as there are different registrations of such
Shares.

     If this Letter of Transmittal is signed by the registered holder(s) of the
Shares surrendered hereby, no endorsements of Share Certificates or separate
stock powers are required, unless payment is to be made to a person other than
the registered holder(s), in which case the Share Certificate(s) evidencing the
Shares surrendered hereby must be endorsed or accompanied by appropriate stock
powers, in either case signed exactly as the name(s) of the registered holder(s)
appear(s) on such Share Certificate(s). Signatures on such Share Certificate(s)
and stock powers must be guaranteed by an Eligible Institution.

     If this Letter of Transmittal is signed by a person other than the
registered holder(s) of the Shares tendered hereby, the Share Certificate(s)
evidencing the Shares surrendered hereby must be endorsed or accompanied by
appropriate stock powers, in either case signed exactly as the name(s) of the
registered holder(s) appear(s) on such Stock Certificate(s). Signatures on such
Share Certificate(s) and stock powers must be guaranteed by an Eligible
Institution.

     If this Letter of Transmittal or any Share Certificate or stock power is
signed by a trustee, executor, administrator, guardian, attorney-in-fact,
officer of a corporation or other person acting in a fiduciary or representative
capacity, such person should so indicate when signing, and proper evidence
satisfactory to Parent of such person's authority so to act must be submitted.

     5.  Stock Transfer Taxes.  Except as otherwise provided in this Instruction
5, the registered holder(s) will pay all stock transfer taxes with respect to
the sale and transfer of any Shares surrendered hereby. If,

                                        4
<PAGE>   5

however, payment of the Merger Price of any Shares is to be made to a person
other than the registered holder(s), the amount of any stock transfer taxes
(whether imposed on the registered holder(s), such other person or otherwise)
payable on account of the transfer to such other person will be deducted from
the Merger Price of such Shares, unless evidence satisfactory to the Paying
Agent of the payment of such taxes, or exemption therefrom, is submitted. Except
as provided in this Instruction 5, it will not be necessary for transfer tax
stamps to be affixed to the Share Certificates evidencing the Shares surrendered
hereby.

     6.  Special Payment and Delivery Instructions.  If a check for the Merger
Price of any Shares surrendered hereby is to be issued in the name of a person
other than the person(s) signing this Letter of Transmittal or if such check is
to be sent to someone other than the person(s) signing this Letter of
Transmittal or to the person(s) signing this Letter of Transmittal but at an
address other than that shown in the box entitled "Description of Shares
Surrendered" on the reverse hereof, the appropriate boxes on the reverse of this
Letter of Transmittal must be completed.

     7.  Questions and Requests for Assistance or Additional Copies.  Questions
and requests for assistance may be directed to the Paying Agent at the address
and phone number set forth on the front side hereof.

     8.  Substitute Form W-9.  The surrendering shareholder (or other payee) is
required, unless an exemption applies, to provide the Paying Agent with a
correct Taxpayer Identification Number ("TIN"), generally the stockholder's
social security or Federal employer identification number, and with certain
other information, on Substitute Form W-9, which is provided under "Important
Tax Information" below, and to certify under penalties of perjury, that such
number is correct and that the shareholder (or other payee) is not subject to
backup withholding. If a surrendering shareholder is subject to backup
withholding, he or she must cross out item (2) of the Certification Box on
Substitute Form W-9 before signing such form. Failure to furnish the correct TIN
on the Substitute Form W-9 may subject the tendering shareholder (or other
payee) to a $50 penalty imposed by the Internal Revenue Service and payments of
the proceeds to the tendering shareholder (or other payee) pursuant to the Offer
may be subject to backup withholding tax at a rate of 31%. If the tendering
shareholder has not been issued a TIN and has applied for a number or intends to
apply for a number in the near future, he or she should write "Applied For" in
the space provided for the TIN in Part I, sign and date the Substitute Form W-9
and sign and date the Certificate of Awaiting Taxpayer Identification Number set
forth below such form. If "Applied For" is written in Part I and Paying Agent is
not provided with a TIN by the time of payment, the Paying Agent will withhold
31% of all such proceeds payable to such shareholder pursuant to the Merger.

                           IMPORTANT TAX INFORMATION

     Under Federal income tax law, a shareholder surrendering Shares must,
unless an exemption applies, provide the Paying Agent (as payor) with his
correct TIN on Substitute Form W-9 included in this Letter of Transmittal. If
the shareholder is an individual, his TIN is such shareholder's social security
number. If the correct TIN is not provided, the shareholder may be subject to a
$50 penalty imposed by the Internal Revenue Service and payments of the proceeds
to the tendering shareholder (or other payee) pursuant to the Merger may be
subject to backup withholding tax at a rate of 31% of all such proceeds.

     Certain shareholders (including, among others, all corporations and certain
foreign individuals and entities) are not subject to backup withholding. In
order for an exempt foreign shareholder to avoid backup withholding, such person
should complete, sign and submit a Form W-8, Certificate of Foreign Status,
signed under penalties of perjury, attesting to his exempt status. A Form W-8
can be obtained from the Paying Agent. Exempt shareholders, other than foreign
shareholders, should furnish their TIN, write "Exempt" on the face of the
Substitute Form W-9 and sign, date and return the Substitute Form W-9 to the
Paying Agent. See the enclosed "Guidelines for Certification of Taxpayer
Identification Number on Substitute Form W-9" for additional instructions.

     If backup withholding applies, the Paying Agent is required to withhold 31%
of the proceeds paid made to the payee. Backup withholding is not an additional
tax. Rather, the Federal income tax liability of persons

                                        5
<PAGE>   6

subject to backup withholding will be reduced by the amount of tax withheld. If
backup withholding results in an overpayment of taxes, a refund may be obtained
from the Internal Revenue Service.

PURPOSE OF SUBSTITUTE FORM W-9

     To prevent backup withholding on payments that are made to a shareholder
with respect to Shares surrendered pursuant to the Merger, the shareholder is
required to notify the Paying Agent of his correct TIN (or the TIN of any other
payee) by completing the Substitute Form W-9 included in this Letter of
Transmittal certifying (1) that the TIN provided on the Substitute Form W-9 is
correct (or that such shareholder is awaiting a TIN), and that (2) the
shareholder is not subject to backup withholding because (i) the shareholder has
not been notified by the Internal Revenue Service that the shareholder is
subject to backup withholding as a result of a failure to report all interest
and dividends or (ii) the Internal Revenue Service has notified the shareholder
that the shareholder is no longer subject to backup withholding.

WHAT NUMBER TO GIVE THE PAYING AGENT

     The shareholder is required to give the Paying Agent its TIN, generally the
social security number or employer identification number, of the record holder
of the Shares surrendered hereby. If the Shares are in more than one name or are
not in the name of the actual owner, consult the enclosed Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9 for
additional guidance on which number to report. If the surrendering shareholder
has not been issued a TIN and has applied for a number or intends to apply for a
number in the near future, he or she should write "Applied For" in the space
provided for the TIN in Part I, sign and date the Substitute Form W-9 and sign
and date the Certificate of Awaiting Taxpayer Identification Number, which
appears in a separate box below the Substitute Form W-9 and sign and date the
Certificate of Awaiting Taxpayer Identification Number, which appears in a
separate box bellow the Substitute Form W-9. If "Applied For" is written in Part
I and the Paying Agent is not provided with a TIN by the time of payment, the
Paying Agent will withhold 31% of all of the proceeds payable to such
shareholder pursuant to the Merger.

Certification Instructions -- You must cross out item (2) above if you have been notified by the IRS that you are subject
to backup withholding because of underreporting interest or dividends on your tax return. However, if after being
notified by the IRS that you were subject to backup withholding you received another notification from the IRS that you
