         corresponding consolidated figures for the preceding fiscal year, all
         in reasonable detail and satisfactory in scope to Saratoga IV and
         together with an opinion directed to the Company of independent public
         accountants of recognized standing selected by the Company whose
         opinion shall be in scope and substance reasonably satisfactory to
         Saratoga IV;

<PAGE>
                                      -3-

The Company will permit Saratoga IV or its Representatives to discuss such
financial statements, plans and projections with such officers of the Company
and its subsidiaries as Saratoga IV or its Representatives may reasonably
designate.

         3. Effective as of the Closing, Saratoga IV has designated a number of
persons constituting 60% of the Board of Directors of the Company. The Company
agrees not to remove such directors designated by Saratoga IV from the Board of
Directors without cause, but in the event of a removal Saratoga IV may designate
replacement directors. The persons so elected to the Board of Directors shall
serve until the next annual meeting of shareholders of the Company and until his
or her successor is duly elected and qualified. Thereafter, the Company shall at
all times include the number of persons designated by Saratoga IV for election
to the Company's Board of Directors as part of the slate of persons recommended
by the Board of Directors of the Company, and the Company shall cause all shares
in which the Company's management or Board of Directors holds proxies (including
undesignated proxies) to be voted in favor of the election of such designees
except as may otherwise be provided in proxies submitted by shareholders. In the
event that any such designee shall cease to serve as a director for any reason,
the Company shall cause the vacancy caused thereby to be filled by a designee of
Saratoga IV.

         The Company agrees that any designee of Saratoga IV who is appointed or
elected to service on the Company's Board of Directors shall be furnished with
all information generally provided to the Company's Board of Directors, shall
have the same access to information regarding the Company and shall be entitled
to the same perquisites as the Company's other outside directors, including,
without limitation, the reimbursement of travel expenses and the payment of any
fees. The designees of Saratoga IV elected to serve on any committee of the
Board of Directors of the Company shall be provided with, and have access to,
all information regarding the Company and its subsidiaries provided to other
members of such committee.

         The obligations set forth herein shall continue as long as Saratoga IV,
directly or indirectly, owns any Securities (or any securities issued upon
exchange, conversion or exercise thereof or as a distribution thereon).

         4. At all times that Saratoga IV or its subsidiaries shall hold any
Securities (or any securities issued upon exchange, conversion or exercise
thereof or as a distribution thereon), the Company shall grant to Saratoga IV
such other

                                      -4-

management rights, and take such other actions, as are necessary to ensure that
the Securities (and securities issued upon conversion, exchange or exercise
thereof or as a distribution thereon) will qualify as a "venture capital
investment" of Saratoga IV within the meaning of 29 CFR of the regulations of
the United States Department of Labor at part 2510.3-101.

         5. The parties agree that any and all information provided pursuant to
this transaction shall remain confidential, except as required by law, consented

partners.

                               FOURTH AMENDMENT TO
                                 LOAN AGREEMENT,
                             SECURED PROMISSORY NOTE

                               SECURITY AGREEMENT

         THIS FOURTH AMENDMENT TO LOAN AGREEMENT, SECURED PROMISSORY NOTE AND
SECURITY AGREEMENT ("this Fourth Amendment"), is made and effective as of
January __, 2004 (the "Effective Date), by WAYNE R. HELLMAN ("Hellman"), and
ADVANCED LIGHTING TECHNOLOGIES, INC. ("ADLT").

                                   BACKGROUND

         A.       Hellman and ADLT entered into a Loan Agreement dated as of
October 8, 1998 (the "Original Loan Agreement"), pursuant to which ADLT advanced
Hellman $9,000,000 (the "Original Advance").

         B.       Pursuant to the Original Loan Agreement, the Original Advance
was evidenced by a Secured Promissory Note dated October 8, 1998 (the "Original
Note") and secured pursuant to (i) a Security Agreement dated as of October 8,
1998 (the "Original Security Agreement"), (ii) the Real Estate Mortgages
recorded as follows: June 30, 1999 Geauga County Ohio No 1245 page 39, June 30,
1999 Portage County Ohio No. 441 Page 202 and No. 441 Page 214, and August 24,
1999 Lee County Florida Book 3160 Page 1096 (the "Mortgages"), (iii) the
Collateral Assignment of Contract dated as of October 8, 1998 (the
"Assignment"), and (iv) Allonge No. 2 to Promissory Note From 24 Karat Street,
Inc. with delivery of the referenced note the (the "Karat Note").

         C.       Effective November 22, 2000, the Loan, the Note and the
Security Agreement were amended pursuant to the First Amendment to Loan
Agreement, Secured Promissory Note and Security Agreement ("First Amendment") to
provide for additional loans, up to a maximum additional principal amount of
$1,900,000, for the purpose of reducing the Margin Loans held by Bear Stearns
and Raymond James, the then current Margin Lenders, in satisfaction of
then-existing margin calls.

         D.       Effective March 15, 2001, the Loan, the Note and the Security
Agreement were amended pursuant to the Second Amendment to Loan Agreement,
Secured Promissory Note and Security Agreement ("Second Amendment") to provide
for additional loans, for the purpose of reducing the Margin Loans held by Bear
Stearns and Raymond James, in satisfaction of then-existing margin calls.

         E.       On March 15, 2001 and thereafter, Advanced Lighting made
Additional Advances pursuant to the Second Amendment in the aggregate principal
amount of $1,889,350.

                                  Page 1 of 7
<PAGE>

         F.       Effective April 25, 2002, the Loan, the Note and the Security
Agreement were amended pursuant to the Third Amendment to Loan Agreement,
Secured Promissory Note and Security Agreement ("Third Amendment") to prohibit
any pledge of shares of ADLT stock owned by Hellman without consent of ADLT as
long as the Loan was outstanding, to amend the interest rate payable on the Loan
and to provide adequate time for Hellman to pay the principal of, and interest
on, the Loan. The Original Loan Agreement, the Original Note and the Original
Security Agreement, each as amended by the First Amendment, the Second Amendment
and the Third Amendment, are referred to herein as the Loan Agreement, the Note
and the Security Agreement, respectively.

         G.       The Loan Agreement, the Note, the Security Agreement, the
Mortgages, the Assignment and the Karat Note are included in the "Loan
Documents" as defined in the Loan Agreement. For purposes of this Fourth
Amendment, the term "Loan Documents" also includes the First, Second, Third, and
Fourth Amendments, and the Settlement Agreement, as defined below. All initially
capitalized terms that are used but not defined herein have the meaning ascribed
to them in the Loan Documents.

         H.       Hellman has demonstrated that the total value of his personal
assets is inadequate to satisfy the outstanding principal and interest on the
Loan and the other obligations secured by interests in his assets with priority
over the security interests of ADLT. ADLT has, in accordance with generally
accepted accounting principles, recognized this situation by impairing, from
time to time, the value of the Loan on the balance sheet of ADLT. Hellman has
advised ADLT, and ADLT's bankruptcy counsel has confimed, that ADLT would not
recover an amount in excess of the value of Hellman's assets, less the amount
obligations secured by security interests senior to ADLT's interests (to the
extent of the value of the property securing such obligations), if Hellman were
to file a bankruptcy proceeding. In recognition of (i) the difficulty and cost
of instituting a collection proceeding against Hellman, (ii) the complexity of
such a proceeding, (iii) the fact that such proceeding would likely be followed
by a bankruptcy petition by Hellman, and (iv) that the costs entailed in any
such proceeding would reduce the amounts available to ADLT for satisfaction of
the Loan, the independent members of the board of directors of ADLT have
determined it to be in the best interests of ADLT to enter into this Fourth
Amendment to resolve these issues concurrently with the emergence of ADLT from
its bankruptcy proceedings.

         I        On February 5, 2003, ADLT and various of its affiliates
(collectively, the "Debtors") each filed a voluntary petition for relief under
chapter 11 of title 11 of the United States Code. The Debtors' bankruptcy cases
are jointly administered in the United States Bankruptcy Court for the Northern
District of Illinois, Eastern Division (the "Bankruptcy Court") under Case No.
03 B 05255.

         J.       Hellman, ADLT and Saratoga Lighting Holdings LLC ("Saratoga")
have entered into that certain Settlement Agreement (the "Settlement Agreement")
of even date herewith, following approval of an order by the Bankruptcy Court
pursuant to a

                                  Page 2 of 7
<PAGE>

motion by ADLT for authority to enter into the Settlement Agreement and this
Fourth Amendment.

                                    AGREEMENT

         NOW THEREFORE, as an inducement to and in consideration of the
agreement by ADLT to eliminate the outstanding interest on and to reduce the
outstanding principal of the Loan and the other agreements made herein, and for
other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, and subject to the express approval by the Bankruptcy Court
of this Fourth Amendment, Hellman and ADLT agree as follows:

         1.       The Loan Agreement is hereby amended to provide that the
accrued and unpaid interest on the Loan is hereby reduced to zero and the
principal amount of the Loan is reduced to the Designated Amount, as set forth
on Exhibit 6 to this Fourth Amendment, the parties expressly acknowledge that
the effectiveness of this Fourth Amendment is subject to approval by the
Bankruptcy Court and that it will not be valid or enforceable against any party
absent such approval.

         2.       The Maturity Date of the Note is July 31, 2007, subject to
mandatory prepayments as provided in this Fourth Amendment. From and after the
Effective Date, the principal amount of the Loan shall bear simple interest at
the lowest rate from time to time charged on outstanding amounts borrowed by
ADLT under its principal United States revolving credit facility. If there is no
such facility at any time, the rate of interest borne by the Loan and Additional
Advances shall be the prime rate as published in The Wall Street Journal from
time to time. The outstanding principal amount and all accrued interest shall
become due and payable immediately if Hellman ceases to be an employee of ADLT,
as a result of a voluntary resignation or a termination for "cause," as defined
in the Amended and Restated Employment Agreement between Hellman and ADLT, as it
may be amended, restated or renewed from time to time. ADLT reserves the right
to require immediate repayment if ADLT requires the payment to prevent an
unacceptable strain on cash resources.

         3.       Hellman acknowledges and agrees that (i) (a) the Security
Interest granted in the Security Agreement, (b) the liens granted in the
Mortgages, (c) the rights of ADLT under the Assignment and Karat Note and (d)
all other rights and instruments that now or hereafter secure the Loan and
Hellman's Obligations with respect thereto, secure the Additional Advances as
amounts advanced to Hellman under the Loan Documents, (ii) the aggregate
outstanding principal amount of the Loan and Additional Advances prior to the
effect of this Fourth Amendment was $12,789,350 and (iii) in addition to, and
without limiting the descriptions of Collateral contained in any of the Loan
Documents, the Collateral includes all choses in action in which Hellman is
directly or indirectly the plaintiff and the proceeds from all choses in action,
and Hellman shall immediately notify ADLT of any such choses in action and take
all necessary action to enable ADLT to perfect its interest in such choses in
action. Hellman expressly acknowledges, agrees and reaffirms the validity and
enforceability of all of the Loan Documents as modified by this Fourth Amendment
and the Settlement Agreement, and

                                  Page 3 of 7
<PAGE>

waives any and all defenses that he has asserted or could assert to defeat
ADLT's right to enforce the Loan Documents, as so modified.

         4.       Hellman represents and warrants to ADLT that on the date
hereof (i) he is not in breach of any covenant in any Loan Document, (ii) all
representations and warranties in the Loan Documents are true and correct except
as has been disclosed to ADLT in writing, (iii) that the assets included in the
calculation of the Designated Amount, a description of which has been provided
to the ADLT Board of Directors and their advisors, constitute all of his assets
available for the payment of the Loan on the Effective Date and (iv) that
Hellman has no reason to believe that the valuation of such assets used in the
calculation of the Designated Amount is not correct in all material respects and
confirms his representations in Paragraph 5 of the Settlement Agreement.

         5.       Hellman acknowledges and agrees that he shall not directly or
indirectly, in one or a series of transactions, obtain loans directly or
indirectly secured by the Margin Shares, until the Loan and Additional Advances,
together with all accrued interest thereon, shall have been paid in full,
without the prior written consent of the ADLT Board of Directors or its
designee(s).

         6.       Hellman acknowledges and agrees that he will make immediate
payments of the outstanding principal and interest on the Loan in the amount of
(i) the after-tax proceeds of any bonuses payable by ADLT or any affiliate,
which after-tax proceeds will be subject to an express right of offset by ADLT,
(ii) the after-tax proceeds of any sales of any and all Collateral and any other
amounts received by Hellman in respect of such Collateral and (iii) the
after-tax proceeds of any Margin Shares.

         7.       Hellman acknowledges and agrees that he will use his best
efforts to sell such items of Collateral as may be designated by the Board of
Directors, or its designee(s), from time to time, provided that, unless Hellman
shall be in default of his prepayment obligations pursuant to paragraph 6 of
this Fourth Amendment or his obligations to sell Collateral pursuant to this
paragraph 7, the Board of Directors may not require the sale of the residence
located in Lee County, Florida. Nothing in this paragraph 7 shall prevent ADLT
from exercising any and all of its rights under its Mortgage on such Florida
property, in accordance with the terms of such mortgage, in the event of a
default by Hellman on any obligations under the Loan Documents or in case any
voluntary or involuntary case in bankruptcy filed by or against Hellman.

         8.       Hellman agrees that to the extent Hellman's interests in and
to (a) H&F V LLC, (b) the proceeds from his settlement with Prudential of
approximately $1,331,000 and (c) his rights under a loan owed to Hellman by
Louis Fisi have not occurred prior to the effective date of this Fourth
Amendment, Hellman will promptly take all steps reasonably necessary to effect
the transfers of such interests.

         8.       Hellman will take all actions and execute all instruments as
requested by ADLT , in order to perfect, and keep perfected, all liens in any of
the Collateral granted to ADLT, including in any after acquired Collateral and
to perfect rights with respect to

                                  Page 4 of 7
<PAGE>

the Additional Advances.

         9.       This Fourth Amendment shall be governed by and construed in
accordance with the laws of Ohio without regard to conflict of laws principles
(except to the extent the Collateral is situated in a state other than Ohio and
in that case any laws of such state which are required to control mortgages
granted on such property shall apply).

         10.      This Fourth Amendment inures to the benefit of and is binding
upon Hellman, and his estate, heirs, executors, administrators and personal
representatives, successors and assigns and ADLT and its successors and assigns.
Hellman may not assign or delegate this Amendment, any Loan Document or any of
his rights or obligations thereunder.

         11.      This Fourth Amendment may be executed in any number of
counterparts, each of which shall be regarded as an original and all of which
shall constitute but one and the same instrument; it shall not be necessary in
proving this Agreement to produce or account for more than one such counterpart.
A faxed executed counterpart of this Amendment will be considered an original
for evidentiary purposes.

         12.      This Fourth Amendment only modifies the Loan Documents to the
extent provided for herein, and the Loan Documents otherwise remain in full
force and effect without interruption. This Fourth Amendment may not be amended,
changed, modified, altered or terminated and no performance may be waived except
in writing executed by both parties.

         13.      This Fourth Amendment and the Loan Documents, including,
without limitation, the Settlement Agreement, constitute the entire agreement
between the parties with respect to the Loan Documents and all prior and
contemporaneous agreements or discussions, written or oral, with respect thereto
have no force or effect whatsoever. If any amendment of the terms of the Loan
Documents contained in this Fourth Amendment shall be contrary to applicable
law, such amendment shall be of no force or effect and the Loan Documents shall
remain in full force and effect without any such amendment.

         IN WITNESS WHEREOF, Hellman and ADLT have caused this Amendment to be
duly executed and delivered as of the Effective Date.
