         Re: $125,000,000 Senior Secured Credit Facilities
             Commitment Letter


Ladies and Gentlemen:

You have advised NationsBank, N.A. ("NATIONSBANK"), NationsBanc Montgomery
Securities LLC ("NMS") and Credit Suisse First Boston ("CSFB") that Fremont
Investors I, LLC or one of its affiliates (the "BUYER") intends to invest in a
leveraged recapitalization (the "TRANSACTION") of Juno Lighting, Inc. (the
"BORROWER"), as more specifically described in the Sources and Uses Table
attached hereto as Schedule I, with the respective amounts expended in
connection therewith being set forth therein. References herein to the
"Transaction" shall include the financing described herein, and all other
transactions related to the Transaction.

You have also advised NationsBank, NMS and CSFB that you propose to finance the
Transaction, the related premiums, fees and expenses and the ongoing general
corporate needs of the Borrower and its subsidiaries after completion of the
Transaction from the following sources: (a) not less than $106 million in common
and preferred equity on terms to be agreed upon by you and us (the "EQUITY
FINANCING"), (b) approximately $90.5 million from senior credit facilities (the
"SENIOR CREDIT FACILITIES") of the Borrower comprised of term loan facilities
aggregating $90 million (the "TERM LOAN FACILITIES") and a $35 million revolving
credit facility (the "REVOLVING CREDIT FACILITY"), (c) at least $125 million in
gross proceeds from the Borrower's issuance of senior subordinated unsecured
notes (the "SENIOR SUBORDINATED NOTES") and (d) existing cash balances of the
Borrower. The Revolving Credit Facility will also be used to finance the
continuing operations of the Borrower and its subsidiaries after consummation of
the Transaction.

In connection with the foregoing and upon and subject to the terms and
conditions of this letter and the Summary of Terms and Conditions attached
hereto as Exhibit A (the "TERM SHEET"), (a) NationsBank is pleased to advise you
of its commitment (this letter being the "COMMITMENT LETTER") to provide
$81,250,000 of the Senior Credit Facilities, and (b) CSFB is pleased to advise
you of its commitment to provide $43,750,000 of the Senior Credit Facilities.
The commitments of NationsBank and CSFB are several and shall be allocated
ratably among the Senior Credit Facilities. NMS is pleased to advise you of its
willingness to form a syndicate of financial institutions (the "LENDERS")
reasonably acceptable to you, NationsBank and CSFB for the Senior Credit
Facilities.

NationsBank will act as the sole and exclusive administrative agent (in such
capacity, the "ADMINISTRATIVE AGENT") for the Senior Credit Facilities. NMS will
act as the sole and exclusive lead arranger and book manager for the Senior
Credit Facilities. CSFB will be named as syndication agent (the "SYNDICATION
AGENT") for the Senior Credit Facilities. No additional agents, co-agents or
arrangers will be appointed and no other titles will be awarded without the
prior written approval of NationsBank, NMS and CSFB.

NMS will syndicate and arrange the Senior Credit Facilities, in consultation
with CSFB. You agree to take reasonable steps to actively assist, and to cause
the Borrower to assist, NMS in achieving a syndication of

   2

the Senior Credit Facilities that is reasonably satisfactory to NMS and CSFB.
Such assistance by you and the Borrower shall include (a) your providing and
causing your advisors to provide NMS, NationsBank, CSFB and the other Lenders
upon request with all information reasonably deemed necessary by NMS to complete
syndication, including, but not limited to, information and evaluations prepared
by the Buyer, the Borrower and their advisors, or on their behalf, relating to
the Transaction; (b) assistance in the preparation of an Offering Memorandum to
be used in connection with the syndication; (c) your using commercially
reasonable efforts to ensure that the syndication efforts benefit materially
from existing lending relationships of the Buyer and the Borrower; and (d)
otherwise assisting NMS in its syndication efforts, including by making senior
management and advisors of the Buyer, the Borrower and its subsidiaries
available from time to time on reasonable notice to attend and make
presentations regarding the business and prospects of the Borrower and its
subsidiaries, as appropriate, at one or more meetings of prospective Lenders.

It is understood and agreed that NationsBank and NMS, after consultation with
CSFB and you, will manage and control all aspects of the syndication, including
decisions as to the selection of proposed Lenders and any titles offered to
proposed Lenders, when commitments will be accepted and the final allocations of
the commitments among the Lenders. It is understood that no Lender participating
in the Senior Credit Facilities will receive compensation from you in order to
obtain its commitment, except on the terms contained herein and in the Term
Sheet. It is also understood and agreed that the amount and distribution of the
fees among the Lenders will be at NMS's sole discretion and that any syndication
prior to execution of the definitive documentation for the Senior Credit
Facilities will reduce ratably the commitments of NationsBank and CSFB.

In the event that such syndication cannot be achieved in a manner satisfactory
to NationsBank and NMS under the structure outlined in the Term Sheet, you agree
that NationsBank and NMS shall be entitled, in consultation with CSFB and you,
to change the pricing (exclusive of the fees provided for in the Fee Letter, as
later defined herein), structure or other terms of the Senior Credit Facilities
if NationsBank and NMS determine that such changes are advisable to achieve a
syndication that is reasonably satisfactory to NationsBank and NMS, provided
that (i) the total amount of the Senior Credit Facilities remains unchanged,
(ii) interest rates on the Senior Credit Facilities shall not be increased by
more than 0.25% over the applicable percentages as shown in the attached Term
Sheet, (iii) the maturity and amortization schedule of the Senior Credit
Facilities as set forth in the attached Term Sheet shall not be changed in such
a manner which shall materially restrict the Borrower's operational flexibility,
(iv) the financial covenant ratios contained in the Credit Agreement signed at
closing shall not be made materially more restrictive after closing, and (v) the
pricing, terms and structure of the Senior Credit Facilities are reasonably
consistent with comparable syndications occurring in the market. The agreement
in this paragraph shall survive closing of the Senior Credit Facilities.

The commitments of NationsBank and CSFB hereunder and the agreement of NMS to
provide the services described herein are subject to the agreement in the
preceding paragraph and the satisfaction of each of the following conditions
precedent in a manner acceptable to each of NMS, NationsBank and CSFB in their
sole discretion: (a) each of the terms and conditions set forth herein and in
the Term Sheet; (b) the proceeds from the Senior Subordinated Notes, the Equity
Financing, and the cash balances of the Borrower at the closing of the Senior
Credit Facilities, together with approximately $91 million from the Senior
Credit Facilities, shall be sufficient to finance the Transaction; (c) the
absence of a material breach of any representation, warranty or agreement of the
Buyer set forth herein; (d) execution by the Buyer and the Borrower and/or other
appropriate parties of a definitive purchase agreement and other related
documentation for the Transaction (collectively, the "TRANSACTION DOCUMENTS"),
which Transaction Documents shall be in form and substance reasonably
satisfactory to NMS, NationsBank and CSFB; (e) NMS, NationsBank and CSFB shall
be satisfied that prior to and during the syndication of the Senior Credit
Facilities there shall be no competing offering, placement or arrangement of any
debt securities or bank financing by or on behalf of the Borrower (other than
the Senior Subordinated Notes described herein); (f) the negotiation, execution
and delivery of definitive documentation for the Senior Credit Facilities
consistent with the Term Sheet and otherwise reasonably satisfactory to NMS,
NationsBank and CSFB (the "CREDIT AGREEMENT DOCUMENTS"); (g) no material adverse
change in or material disruption of conditions in

the financial, banking or capital markets which NMS, NationsBank or CSFB, in
their reasonable discretion, deem material in connection with the syndication of
the Senior Credit Facilities shall have occurred and be continuing; (h) no
change, occurrence or development that could, in the reasonable opinion of NMS,
NationsBank or CSFB, have a material adverse effect on the business, assets,
liabilities (actual or contingent), operations, condition (financial or
otherwise) or prospects of the Borrower and its subsidiaries taken as a whole,
shall have occurred or become known to NMS, NationsBank or CSFB; and (i) NMS,
NationsBank and CSFB not becoming aware after the date hereof of any information
or other matter which in any of their judgment is inconsistent in a material and
adverse manner with any information or other matter disclosed to any of them
prior to the date hereof (in which case NMS may, in its sole discretion, suggest
alternative financing amounts or structures that ensure adequate protection for
the Lenders or terminate this letter and any commitment or undertaking
hereunder).

You hereby represent, warrant and covenant that (a) to your knowledge, all
information, other than the Projections (defined below), which has been or is
hereafter made available to NMS, NationsBank, CSFB or the Lenders by you or any
of your repres.entatives in connection with the transactions contemplated hereby
(the "INFORMATION") is and, as of its date, will be complete and correct in all
material respects and does not and will not contain any untrue statement of a
material fact or omit to state a material fact necessary to make the statements
contained therein not misleading, and (b) all financial projections concerning
the Borrower and its subsidiaries that have been or are hereafter made available
to NMS, NationsBank, CSFB or the Lenders by you or any of your representatives
(the "PROJECTIONS") have been or will be prepared in good faith based upon
assumptions you believe to be reasonable. You agree to furnish NMS, NationsBank
and CSFB with such Information and Projections as they may reasonably request
(including due diligence investigations of the Borrower prepared by accountants
and advisors of the Buyer to the extent permitted by such accountants and
advisors) and to supplement the Information and the Projections from time to
time until the closing date for the Senior Credit Facilities so that the
representation, warranty and covenant in the preceding sentence is correct on
such closing date. You understand that in arranging and syndicating the Senior
Credit Facilities, NationsBank, NMS and CSFB will be using and relying on the
Information and the Projections without independent verification thereof. We
acknowledge that the Projections are subject to significant contingencies and
uncertainties, many of which are beyond your control, and that there can be no
assurance that the Projections will be realized.

By acceptance of this offer, you agree to pay all reasonable out-of-pocket fees
and expenses (including the reasonable fees and expenses of Jones, Day, Reavis &
Pogue, counsel for the Administrative Agent and the Syndication Agent, and due
diligence expenses) incurred before or after the date hereof by NMS, NationsBank
and CSFB in connection with the Senior Credit Facilities, the syndication
thereof and the other transactions contemplated hereby; provided, however, that
the aggregate fees and expenses incurred before March 26, 1999, shall not exceed
$6,500 for NMS and NationsBank and $3,500 for CSFB.

You agree to indemnify and hold harmless NationsBank, NMS, CSFB and each of
their respective affiliates and their respective directors, officers, employees,
advisors and agents (each, an "INDEMNIFIED PARTY") from and against (and will
reimburse each Indemnified Party as the same are incurred) any and all losses,
claims, damages, liabilities, and expenses (including, without limitation, the
reasonable fees and expenses of outside counsel) that may be incurred by or
asserted or awarded against any Indemnified Party, in each case arising out of
or in connection with or by reason of (including, without limitation, in
connection with any investigation, litigation or proceeding or preparation of a
defense in connection therewith) (a) the Transaction or any similar transaction
and any of the other transactions contemplated thereby, or (b) the Senior Credit
Facilities or any other financings, or any use made or proposed to be made with
the proceeds thereof (including any arising out of the negligence of any
Indemnified Party), unless and only to the extent that, as to any Indemnified
Party, it shall be determined in a final, non-appealable judgment by a court of
competent jurisdiction that such losses, claims, damages, liabilities or
expenses resulted from the gross negligence or willful misconduct of such
Indemnified Party. In the case of any investigation, litigation or proceeding to
which the indemnity in this paragraph applies, such indemnity shall be effective
whether or not such investigation, litigation or proceeding is brought by you,
your shareholders or creditors or an Indemnified Party and whether or not the
Transaction is consummated. You agree that no Indemnified

Party shall have any liability to you or your subsidiaries or affiliates or to
your or their respective security holders or creditors for any indirect or
consequential damages arising out of, related to or in connection with the
Transaction or any of the financings.

The terms of this Commitment Letter, the Term Sheet and the fee letter among
you, NMS, NationsBank and CSFB of even date herewith (the "FEE LETTER") are
confidential and, except for disclosure on a confidential basis to your
accountants, attorneys and other professional advisors retained by you in
connection with the Senior Credit Facilities or as may be required by law, may
not be disclosed in whole or in part to any other person or entity (including
the Borrower) without the prior written consent of NMS, NationsBank and CSFB;
provided, however, it is understood and agreed that you may disclose the terms
of this Commitment Letter and the Term Sheet (but not the Fee Letter) (i) on a
confidential basis to the board of directors and advisors of the Borrower in
connection with their consideration of the Transaction, and (ii) after your
acceptance of this Commitment Letter and the Fee Letter, in filings with the SEC
and other applicable regulatory authorities and stock exchanges, and in proxy
and other materials disseminated to stockholders and other purchasers of
securities of the Borrower.

The provisions of the immediately preceding three paragraphs shall remain in
full force and effect regardless of whether any definitive documentation for the
Senior Credit Facilities shall be executed and notwithstanding the termination
of this Commitment Letter or any commitment or undertaking hereunder; provided,
however, that the Buyer shall be deemed released from its reimbursement and
indemnification obligations hereunder upon the execution of all the Credit
Agreement Documents.

In connection with the services and transactions contemplated hereby, the Buyer
agrees that NationsBank, NMS and CSFB are permitted to access, use and share (on
a confidential basis) with any of their respective bank or non-bank affiliates,
agents, advisors (legal or otherwise) or representatives, any information
concerning the Buyer, the Borrower or any of their respective affiliates that is
or may come into the possession of NationsBank, NMS, CSFB or any of such
affiliates. NationsBank, NMS, CSFB and their respective affiliates will treat
confidential information relating to the Buyer, the Borrower and their
respective affiliates with the same degree of care as they treat their own
confidential information.

This Commitment Letter and the Fee Letter shall be governed by laws of the State
of New York. Each of us hereby irrevocably waives all right to trial by jury in
any action, proceeding or counterclaim (whether based on contract, tort or
otherwise) arising out of or relating to this Commitment Letter, the Term Sheet,
the Fee Letter, the transactions contemplated hereby and thereby or the actions
of NationsBank, NMS and CSFB in the negotiation, performance or enforcement
hereof.

This Commitment Letter supersedes that certain commitment letter dated March 26,
1999, issued by NMS and NationsBank to Fremont Investors I, LLC (the "PRIOR
COMMITMENT LETTER"), and this Commitment Letter, together with the Term Sheet
and the Fee Letter, set forth the entire understanding of the parties with
respect to the Senior Credit Facilities. The Buyer, NMS, and NationsBank hereby
terminate the Prior Commitment Letter and agree that neither NMS, NationsBank
nor Fremont Investors I, LLC shall have any liabilities or obligations
thereunder, including those obligations that expressly survive any termination
of the Prior Commitment Letter. This Commitment Letter may be modified or
amended only by the written agreement of all of the parties hereto. This
Commitment Letter is not assignable by you without the prior written consent of
NMS, NationsBank and CSFB and is intended to be solely for the benefit of the
parties hereto and the Indemnified Parties. Upon execution of a Credit Agreement
by the Borrower, the Buyer shall be released from all obligations hereunder, and
this Commitment Letter shall be of no further force or effect, except to the
extent that the Buyer's obligations hereunder are assumed by the Borrower.

This offer will expire at 5:00 p.m. CST on April 7, 1999 unless you execute this
Commitment Letter and the Fee Letter and return them to NMS prior to that time
(which may be by facsimile transmission), whereupon this Commitment Letter and
the Fee Letter (each of which may be signed in one or more counterparts) shall
become binding agreements. Thereafter, this undertaking and commitment will
expire on the earliest to occur of (a) the closing of the Transaction without
the use of the Senior Credit Facilities, (b) the acceptance

by the Borrower or any of its affiliates of an offer for all or any substantial
part of the capital stock or assets of the Borrower other than the offer
contemplated hereby, and (c) July 31, 1999, unless definitive documentation for
the Senior Credit Facilities is executed and delivered prior to such date.

THIS WRITTEN AGREEMENT (WHICH INCLUDES THE SUMMARY OF TERMS AND CONDITIONS) AND
THE FEE LETTER REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE
CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL
AGREEMENTS OF THE PARTIES. THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE
PARTIES.

We are pleased to have the opportunity to work with you in connection with this
important financing.

Very truly yours,

NATIONSBANK, N.A.
