                      ADVANCED LIGHTING TECHNOLOGIES, INC.
                            STOCK PURCHASE AGREEMENT

      THIS PURCHASE AGREEMENT ("Purchase Agreement") is dated as of May 25,
2004 between ADVANCED LIGHTING TECHNOLOGIES, INC. (the "Company"), and Robert
Cizik ("Purchaser").

                                   WITNESSETH:

      WHEREAS, the Company has given Purchaser an award attached hereto as ANNEX
2 (the "Award");

      WHEREAS, the Award permits Purchaser to purchase up to 20 shares of the
Company's common stock within 30 days of the Date of Grant specified in the
Award; and

      WHEREAS, pursuant to the Award, Purchaser desires to purchase shares of
the Company as herein described, on the terms and conditions set forth in this
Purchase Agreement and the Award. Certain capitalized terms used in this
Purchase Agreement are defined in ANNEX 1 attached hereto.

      NOW, THEREFORE, it is agreed between the parties as follows:

1.    PURCHASE OF SHARES.

      Pursuant to the terms of the Award, Purchaser hereby agrees to purchase
from the Company and the Company agrees to sell and issue to Purchaser 20 shares
of the Company's common stock (the "Stock") for the Purchase Price Per Share
specified in the Award payable by personal check, cashier's check or money
order. Payment shall be delivered at the Closing, as such term is hereinafter
defined. The closing hereunder (the "Closing") shall occur at the offices of the
Company on June 24, 2004, or such other time and place as may be designated
by the Company (the "Closing Date").

2.    REPURCHASE OF UNVESTED STOCK.

      All unvested shares of the Stock purchased by Purchaser pursuant to this
Purchase Agreement (sometimes referred to as the "Unvested Stock") shall be
subject to the following repurchase requirement (the "Unvested Stock
Requirement"):

      In the event Purchaser ceases to be an Employee of the Company, i.e.
terminates Service with the Company for any reason, the Company shall purchase
the Unvested Stock as hereinafter provided. Purchaser understands that the Stock
is being sold in order to induce Purchaser to become and/or remain associated
with the Company and to work diligently for the success of the Company and that
the Unvested Stock will vest in accordance with the schedule set forth in the
Award.

<PAGE>

      Nothing in this Purchase Agreement shall be construed as a right by
Purchaser to be employed by Company, or a parent or subsidiary of Company.

3.    ESCROW OF STOCK.

      As security for Purchaser's faithful performance of the terms of this
Purchase Agreement and to ensure the availability for delivery of Purchaser's
shares upon repurchase by the Company, Purchaser agrees at the Closing
hereunder, to deliver to and deposit with the Escrow Agent named in the Joint
Escrow Instructions attached hereto as EXHIBIT C, the certificate or
certificates evidencing the Unvested Stock and five Assignments Separate from
Certificate duly executed (with date and number of shares in blank) in the form
attached hereto as EXHIBIT D. Such documents are to be held by the Escrow Agent
and delivered by the Escrow Agent pursuant to the Joint Escrow Instructions,
which instructions shall also be delivered to the Escrow Agent at the Closing
hereunder.

      Within 30 days after each anniversary of the Grant Date (as defined in the
Award), if Purchaser so requests, the Escrow Agent will deliver to Purchaser
certificates representing so many shares of Stock as are no longer subject to
the Unvested Stock Requirement (less such shares as have been previously
delivered).

4.    ADJUSTMENT OF SHARES.

      Subject to the provisions of the Articles of Incorporation of the Company,
if, from time to time during the term of the Unvested Stock Requirement:

      (a)   there is any stock dividend or liquidating dividend of cash and/or
property, stock split or other change in the character or amount of any of the
outstanding securities of the Company, or

      (b)   there is any consolidation, merger or sale of all or substantially
all, of the assets of the Company,

then, in such event, any and all new, substituted or additional securities or
other property to which Purchaser is entitled by reason of Purchaser's ownership
of the shares of Stock shall be immediately subject to such Unvested Stock
Requirement with the same force and effect as the shares from time to time
subject to the Unvested Stock Requirement. While the total Purchase Price shall
remain the same after each such event, the Purchase Price Per Share of Unvested
Stock shall be appropriately and equitably adjusted as determined by the Board
of Directors of the Company.

5.    THIRD PARTY TRANSFER RESTRICTIONS.

      5.1   Prior to a Major Event. (a) Vested Stock. Prior to the occurrence of
            a Major Event, Purchaser may not transfer vested shares of the Stock
            (the "Vested Stock"), other than by a Permitted Transfer or
            otherwise with the prior written consent of the Company.

                                      -2-
<PAGE>

      (b) Unvested Stock. Purchaser may not transfer the Unvested Stock, other
      than by a Permitted Transfer.

5.2   After a Major Event. (a) Vested Stock. In the event Purchaser proposes to
      sell, pledge or otherwise transfer to a party other than a Permitted
      Transferee, pursuant to a bona fide purchase offer, shares of the Vested
      Stock acquired pursuant to this Purchase Agreement or any interest in such
      Vested Stock at any time after the occurrence of a Major Event and prior
      to the Initial Public Offering, the Company shall have the "Right of First
      Refusal" with respect to all (and not less than all) of such shares of the
      Vested Stock. Purchaser must give a written "Transfer Notice" to the
      Company describing fully the proposed transfer, including the number of
      shares proposed to be transferred, the proposed transfer price and the
      name and address of the proposed transferee and including a copy of the
      bona fide purchase offer. The Transfer Notice shall be signed both by
      Purchaser and by the proposed transferee and must constitute a binding
      commitment of both parties to the transfer of the shares. Such right of
      First Refusal with respect to the Vested Stock shall terminate upon the
      sale of common stock by the Company pursuant to an Initial Public
      Offering.

      The Company and its assignees shall have the right to purchase all, and
      not less than all, of the shares of the Vested Stock on the terms
      described in the Transfer Notice (subject, however, to any change in such
      terms permitted in the next paragraph) by delivery of a Notice of Exercise
      of the Right of First Refusal within 30 days after the date when the
      Transfer Notice was received by the Company.

      If the Company fails to exercise its Right of First Refusal within 30 days
      after the date when it received the Transfer Notice, Purchaser may, not
      later than 60 days following receipt of the Transfer Notice by the
      Company, conclude a transfer of the shares of the Vested Stock subject to
      the Transfer Notice on the terms and conditions described in the Transfer
      Notice. Any proposed transfer on terms and conditions different from those
      described in the Transfer Notice, as well as any subsequent proposed
      transfer by Purchaser, shall again be subject to the Right of First
      Refusal and shall require compliance with the procedure described in the
      paragraph above. If the Company exercises its Right of First Refusal,
      Purchaser and the Company (or its assignees) shall consummate the sale of
      the shares of the Vested Stock on the terms set forth in the Transfer
      Notice; provided, however, that the purchase price for such shares shall
      be the lesser of the price described in such Transfer Notice or Fair
      Market Value and, provided further, however, if at the time of the
      exercise of such Right of First Refusal there shall exist any Company
      Payment Condition, the Company may defer the payment for the purchase
      until such time as the Company Payment Condition no longer exists.

      The Company's Right of First Refusal shall inure to the benefit of its
      successors and assigns and shall be binding upon any transferee of the
      Shares. The

                                      -3-
<PAGE>

      Company's rights under this Subsection shall be freely assignable, in
      whole or in part.

      (b) Unvested Stock. Prior to a termination of Service, Purchaser may not
      transfer any shares of the Unvested Stock, other than pursuant to a
      Permitted Transfer.

5.3   Termination of Service. (a) Prior to a Major Event. Following a
      termination of Service of Purchaser for any reason: (A) the Company shall
      have the right to purchase all or any portion of the Vested Stock of
      Purchaser at any time within 12 months following such termination of
      Service. Such purchase will be at the Fair Market Value of such shares at
      the time of the exercise of such right. To exercise such right, Company
      shall give Purchaser written notice of the sale in the same manner and
      with the same effect as a Compelled Sale, pursuant to Section 5.4;
      provided, however, if at the time of the exercise of such right there
      shall exist any Company Payment Condition, the Company may defer the
      payment for the purchase until such time as the Company Payment Condition
      no longer exists; and (B) the Company will purchase all shares of the
      Unvested Stock of such Purchaser within 60 days of Purchaser's such
      termination of Service, such purchase will be at the Purchase Price Per
      Share paid by Purchaser for all such shares pursuant to the Award;
      provided, however, if at the time of the termination of Service there
      shall exist any Company Payment Condition, the Company may defer the
      payment for the purchase until such time as the Company Payment Condition
      no longer exists. The Company's rights under this Section shall be freely
      assignable, in whole or in part, and, following such assignment, such
      rights will not be limited by any Company Payment Condition.

      (b) After a Major Event. The Company shall not have any obligation to
      purchase any shares of the Vested Stock following Purchaser's termination
      of Service for any reason after the occurrence of a Major Event.

5.4   Right to Compel Sale. (a) Compelled Sale. If members of the Saratoga Group
      propose a Change of Control Transaction, then Saratoga shall have the
      right (whether the Change of Control results from the sale of all, or some
      lesser portion, of the Saratoga Group's shares of the Company's common
      stock) to require Purchaser (or his Permitted Transferee) to sell all, or
      a Pro Rata Portion, of his shares of the Stock to the prospective
      purchaser of the shares owned by Saratoga (if such right is exercised, a
      "Compelled Sale"). If the prospective purchaser in the Change of Control
      Transaction proposed by the Saratoga Group is to acquire shares of the
      Company's common stock owned the Saratoga Group, but Saratoga does not
      elect to cause a Compelled Sale pursuant to the foregoing sentence, then
      Purchaser (or such Permitted Transferee) shall have the right to elect to
      sell to the prospective purchaser, as part of the Change of Control
      Transaction, the Pro Rata Portion of Purchaser's (or such Permitted
      Transferee's) Stock (if such right is exercised, a "Co-Sale"). The
      consideration to be received by Purchaser (or such Permitted Transferee)
      for each share of Stock in the Compelled Sale or Co-Sale shall be the same
      consideration per share to be received by the Saratoga Group,

                                      -4-
<PAGE>

      and the terms and conditions of such sale by Purchaser (or such Permitted
      Transferee) shall be the same as those upon which the Saratoga Group sell
      their shares, except that Purchaser (or such other party) shall not be
      bound by the terms of any indemnity, hold-back or escrow given to the
      prospective purchaser in connection with such sale to the extent that such
      indemnity is not limited in value with respect to Purchaser (or such
      Permitted Transferee) to at most the aggregate consideration to be
      received for his shares of the Stock in such sale.

      (b) Notice and Sale Procedures. (i) The Company shall provide written
      notice to Purchaser (or his Permitted Transferee) of any proposed Change
      of Control Transaction, which notice (a "Control Transaction Notice")
      shall: (A) set forth the consideration per share to be paid by the
      prospective purchaser and (B) state whether Saratoga is electing pursuant
      to Section 5.4(a) to cause a Compelled Sale. If Saratoga does not elect to
      cause a Compelled Sale and Purchaser (or such Permitted Transferee)
      desires to cause a Co-Sale pursuant to Section 5.4(a), Purchaser (or such
      Permitted Transferee) must give written notice of his election to cause
      such Co-Sale (a "Co-Sale Notice") to Saratoga (or the representative of
      Saratoga as may be designated in the Control Transaction Notice) within
      ten (10) days following the date of the Control Transaction Notice. Within
      ten (10) days following the date of the Control Transaction Notice in
      which Saratoga has elected to cause a Compelled Sale, Purchaser (or
      Permitted Transferee) shall deliver to Saratoga (or such designated
      representative), or in the case of a Co-Sale, the Co-Sale Notice shall be
      accompanied by, the certificates representing the shares of the Stock held
      by Purchaser (or Permitted Transferee) to be sold in such Compelled Sale
      or Co-Sale, together with a suitably executed blank stock power and all
      other documents required to be executed in connection with such Change of
      Control Transaction. In the event that Purchaser (or Permitted Transferee)
      should fail to deliver such certificates and other documents as aforesaid,
      the Company shall cause the books and records of the Company to show that
      such shares are bound by the provisions of this Section 5.4 and that such
      shares shall be transferred only to the purchaser identified in the Change
      of Control Notice upon surrender for transfer by Purchaser (or any other
      party) thereof.

      (ii) If, within one hundred twenty (120) days after the Saratoga Group
      gives the notice they have not completed the sale of Saratoga's shares
      described in the notice, the Saratoga Group shall return to Purchaser (or
      such Permitted Transferee) all certificates representing shares that
      Purchaser (or such Permitted Transferee) delivered for sale pursuant
      hereto, together with any such other documents delivered by Purchaser.

      (iii) Promptly after the consummation of the sale of the shares of the
      Saratoga Group and Purchaser (or Permitted Transferee) pursuant to this
      Section, the Saratoga Group shall remit to Purchaser (or Permitted
      Transferee) the total sales price of the shares of the Stock of Purchaser
      (or Permitted Transferee) sold pursuant thereto, and shall furnish such
      other evidence of the completion and time

                                      -5-
<PAGE>

      of completion of such sale or other disposition and the terms thereof as
      may be reasonably requested by Purchaser (or Permitted Transferee).

6.    PURCHASER'S RIGHTS UPON REPURCHASE.

      At such time as the Company makes available, the consideration for the
Stock to be repurchased in accordance with the provisions of Sections 2 and 5 of
this Purchase Agreement, then from and after such time the person from whom such
shares are to be repurchased shall no longer have any rights as a holder of such
shares (other than the right to receive payment of such consideration in
accordance with this Purchase Agreement). Such shares shall be deemed to have
been repurchased in accordance with the applicable provisions hereof, whether or
not the certificate(s) therefor have been delivered as required by this Purchase
Agreement.

7.    TRANSFER BY PURCHASER TO CERTAIN TRUSTS.

      Purchaser shall have the right to transfer all or any portion of
Purchaser's interest in the shares of Stock issued under this Purchase Agreement
which have been delivered to Purchaser under the provisions of Section 3 of this
Purchase Agreement, to a trust established by Purchaser for the benefit of
Purchaser, Purchaser's spouse or Purchaser's children, without being subject to
the provisions of Section 5 hereof, provided that the trustee on behalf of the
trust shall agree in writing to be bound by the terms and conditions of this
Purchase Agreement. The transferee shall execute a copy of EXHIBIT E attached
hereto and file the same with the Secretary of the Company.

8.    LEGEND ON SHARES.

      All certificates representing the Stock purchased under this Purchase
Agreement shall, where applicable, have endorsed thereon the legends set forth
in the Award and any other legends required by applicable securities laws.

9.    PURCHASER'S INVESTMENT REPRESENTATIONS.

      This Purchase Agreement is made with Purchaser in reliance upon
Purchaser's representation to the Company, which by Purchaser's acceptance
hereof Purchaser confirms, that the Stock which Purchaser will receive will be
acquired with Purchaser's own funds for investment for an indefinite period for
Purchaser's own account, not as a nominee or agent, and not with a view to the
sale or distribution of any part thereof, and that Purchaser has no present
intention of selling, granting participation in, or otherwise distributing the
same, but subject, nevertheless, to any requirement of law that the disposition
of Purchaser's property shall at all times be within Purchaser's control. By
executing this Purchase Agreement, Purchaser further represents that Purchaser
does not have any contract, understanding or agreement with any person to sell,
transfer, or grant participation, to such person or to any third person, with
respect to any of the Stock.

      Purchaser understands that the Stock will not be registered or qualified
under federal or state securities laws on the ground that the sale provided for
in this Purchase Agreement is

                                      -6-
<PAGE>

exempt from registration or qualification under federal or state securities laws
and that the Company's reliance on such exemption is predicated on Purchaser's
representations set forth herein.

      Purchaser agrees that in no event will Purchaser make a disposition of any
of the Stock (including a disposition under Section 7 of this Purchase
Agreement), unless and until (i) Purchaser shall have notified the Company of
the proposed disposition and shall have furnished the Company with a statement
of the circumstances surrounding the proposed disposition and (ii) Purchaser
shall have furnished the Company with an opinion of counsel satisfactory to the
Company to the effect that (A) such disposition will not require registration or
qualification of such Stock under federal or state securities laws or (B)
appropriate action necessary for compliance with the federal or state securities
laws has been taken or (iii) the Company shall have waived, expressly and in
writing, its rights under clauses (i) and (ii) of this section.

      With respect to a transaction occurring prior to such date as the Stock is
covered by a valid federal registration statement, this subsection shall apply
unless the transaction is covered by Rule 701 under the Securities Act of 1933,
as amended (the "Securities Act") or another exemption. In connection with the
investment representations made herein, Purchaser represents that Purchaser is
able to fend for himself or herself in the transactions contemplated by this
Purchase Agreement, has such knowledge and experience in financial and business
matters as to be capable of evaluating the merits and risks of Purchaser's
investment, has the ability to bear the economic risks of Purchaser's investment
and has been furnished with and has had access to such information as would be
made available in the form of a registration statement together with such
additional information as is necessary to verify the accuracy of the information
supplied and to have all questions answered by the Company.

      Purchaser understands that if a registration statement covering the Stock
(or a filing pursuant to the exemption from registration under Regulation A of
the Securities Act) under the Securities Act is not in effect when Purchaser
desires to sell the Stock, Purchaser may be required to hold the Stock for an
indeterminate period. Purchaser also acknowledges that Purchaser understands
that any sale of the Stock which might be made by Purchaser in reliance upon
Rule 144 under the Securities Act may be made only in limited amounts in
accordance with the terms and conditions of that Rule.

10.   NO DUTY TO TRANSFER IN VIOLATION HEREUNDER.

      The Company shall not be required (a) to transfer on its books any shares
of Stock of the Company which shall have been sold or transferred in violation
of any of the provisions set forth in this Purchase Agreement or (b) to treat as
owner of such shares or to accord the right to vote as such owner or to pay
dividends to any transferee to whom such shares shall have been so transferred.

                                      -7-

11.   RIGHTS OF PURCHASER.

      Except as otherwise provided herein, Purchaser shall, during the term of
this Purchase Agreement, exercise all rights and privileges of a stockholder of
the Company with respect to the Stock.

12.   SECTION 83(b) ELECTIONS.

      Purchaser hereby acknowledges that he or she has been informed that unless
an election is filed by Purchaser with the Internal Revenue Service and, if
necessary, the proper state taxing authorities, within 30 days of the purchase
of the Shares (and attached to Purchaser's individual income tax return for that
year), electing pursuant to Section 83(b) of the Internal Revenue Code of 1986,
as amended (the "Code") to be taxed currently on any difference between the
purchase price of the Shares and their fair market value on the date of
purchase, there will be a recognition of taxable income to Purchaser, measured
by the excess, if any, of the fair market value of the Shares, at the time the
Company's Unvested Stock Requirement lapses over the purchase price for the
Shares. Purchaser represents that Purchaser has consulted any tax consultant(s)
that Purchaser deems advisable in connection with the purchase of the Shares or
the filing of the Election under Section 83(b). A form of Election under Section
83(b) is attached hereto as EXHIBIT B for reference.

PURCHASER ACKNOWLEDGES THAT IT IS PURCHASER'S SOLE RESPONSIBILITY AND NOT THE
COMPANY'S TO FILE TIMELY THE ELECTION UNDER SECTION 83(b), EVEN IF PURCHASER
REQUESTS THE COMPANY OR ITS REPRESENTATIVE TO MAKE THIS FILING ON HIS OR HER
BEHALF.

13.   OTHER NECESSARY ACTIONS.

      The parties agree to execute such further instruments and to take such
further action as may reasonably be necessary to carry out the intent of this
Purchase Agreement.

14.   NOTICE.

      Any notice required or permitted hereunder shall be given in writing and
shall be deemed effectively given upon the earliest of personal delivery,
receipt or the third full day following deposit in the United States Post Office
with postage and fees prepaid, addressed to the other party hereto at the
address last known or at such other address as such party may designate by 10
days' advance written notice to the other party hereto.

15.   SUCCESSORS AND ASSIGNS.

      This Purchase Agreement shall inure to the benefit of the successors and
assigns of the Company and, subject to the restrictions on transfer herein set
forth, be binding upon Purchaser and Purchaser's heirs, executors,
administrators, successors and assigns. No waiver of any breach or condition of
this Purchase Agreement shall be deemed to be a waiver of any other or
subsequent breach or condition, whether of a like or different nature.

      This Purchase Agreement shall be governed by, and construed in accordance
with, the laws of the State of Ohio, as such laws are applied to contracts
entered into and performed in such state.

17.   NO FEDERAL OR OTHER STATE REGISTRATION.

      THE SALE OF THE SECURITIES WHICH ARE THE SUBJECT OF THIS PURCHASE
AGREEMENT HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 OR THE
SECURITIES LAW OF ANY STATE AND THE ISSUANCE OF SUCH SECURITIES OR THE PAYMENT
OR RECEIPT OF ANY PART OF THE CONSIDERATION THEREFOR PRIOR TO SUCH REGISTRATION

                      ADVANCED LIGHTING TECHNOLOGIES, INC.
                            STOCK PURCHASE AGREEMENT

      THIS PURCHASE AGREEMENT ("Purchase Agreement") is dated as of May 25,
2004 between ADVANCED LIGHTING TECHNOLOGIES, INC. (the "Company"), and Robert
Cizik ("Purchaser").

                              W I T N E S S E T H:

      WHEREAS, Purchaser desires to purchase shares of the Company as herein
described, on the terms and conditions set forth in this Purchase Agreement.
Certain capitalized terms used in this Purchase Agreement are defined in ANNEX 1
attached hereto.

      NOW, THEREFORE, it is agreed between the parties as follows:

1.    PURCHASE OF SHARES.

      Pursuant to the terms of this Purchase Agreement, Purchaser hereby agrees
to purchase from the Company and the Company agrees to sell and issue to
Purchaser 11.67 shares of the Company's common stock and 338.33 shares of the
Company's Series A Preferred stock (collectively, the "Stock") for Three Hundred
Fifty Thousand Dollars ($350,000.00) (the "Purchase Price") payable by wire
transfer, cashier's check or money order at the Closing.

2.    CLOSING.

      Payment shall be delivered from Purchaser to the Company at the Closing,
as such term is hereinafter defined. The closing hereunder (the "Closing") shall
occur at the offices of the Company on June 24, 2004, or such other time and
place as may be designated by the Company (the "Closing Date"). At the Closing,
the Company shall deliver to Purchaser:

      (a)   Share certificates for 11.67 shares of the Company's common stock.

      (b)   Share certificates for 338.33 shares of the Company's Series A
            Preferred stock.

      (c)   Any and all other instruments not herein specifically provided for
            but which are reasonably necessary or desirable to effectuate the
            purposes of this Purchase Agreement.

3.    THIRD PARTY TRANSFER RESTRICTIONS.

      3.1   Right of First Refusal. In the event Purchaser proposes to sell,
            pledge or otherwise transfer to a party other than a Permitted
            Transferee, pursuant to a bona fide purchase offer, shares of the
            Stock acquired pursuant to this Purchase Agreement or any interest
            in such Stock at any time prior to an Initial Public Offering, the
            Company shall have the "Right of First Refusal" with respect to all
            (and not less than all) of such shares of the Stock. Purchaser must
            give a written

<PAGE>

            "Transfer Notice" to the Company describing fully the proposed
            transfer, including the number of shares proposed to be transferred,
            the proposed transfer price and the name and address of the proposed
            transferee and including a copy of the bona fide purchase offer. The
            Transfer Notice shall be signed both by Purchaser and by the
            proposed transferee and must constitute a binding commitment of both
            parties to the transfer of the shares. Such Right of First Refusal
            with respect to the Stock shall terminate upon the sale of common
            stock by the Company pursuant to an Initial Public Offering.

            The Company and its assignees shall have the right to purchase all,
            and not less than all, of the shares of the Stock on the terms
            described in the Transfer Notice (subject, however, to any change in
            such terms permitted in the next paragraph) by delivery of a Notice
            of Exercise of the Right of First Refusal within 30 days after the
            date when the Transfer Notice was received by the Company.

            If the Company fails to exercise its Right of First Refusal within
            30 days after the date when it received the Transfer Notice,
            Purchaser may, not later than 60 days following receipt of the
            Transfer Notice by the Company, conclude a transfer of the shares of
            the Stock subject to the Transfer Notice on the terms and conditions
            described in the Transfer Notice. Any proposed transfer on terms and
            conditions different from those described in the Transfer Notice, as
            well as any subsequent proposed transfer by Purchaser, shall again
            be subject to the Right of First Refusal and shall require
            compliance with the procedure described in the paragraph above. If
            the Company exercises its Right of First Refusal, Purchaser and the
            Company (or its assignees) shall consummate the sale of the shares
            of the Stock on the terms set forth in the Transfer Notice;
            provided, however, that the purchase price for such shares shall be
            the lesser of the price described in such Transfer Notice or Fair
            Market Value and, provided further, however, if at the time of the
            exercise of such Right of First Refusal there shall exist any
            Company Payment Condition, the Company may defer the payment for the
            purchase until such time as the Company Payment Condition no longer
            exists.

            The Company's Right of First Refusal shall inure to the benefit of
            its successors and assigns and shall be binding upon any transferee
            of the Shares. The Company's rights under this Subsection shall be
            freely assignable, in whole or in part.

      3.2   Right to Compel Sale. (a) Compelled Sale. If members of the Saratoga
            Group propose a Change of Control Transaction, then Saratoga shall
            have the right (whether the Change of Control results from the sale
            of all, or some lesser portion, of the Saratoga Group's shares of
            the Company's common stock) to require Purchaser (or his Permitted
            Transferee) to sell all, or a Pro Rata Portion, of his shares of the
            Stock to the prospective purchaser of the shares owned by Saratoga
            (if such right is exercised, a "Compelled Sale"). If the prospective
            purchaser in the Change of Control Transaction proposed by the
            Saratoga Group is to acquire shares of the Company's common stock
            (or Series A Preferred stock) owned the

                                      -2-
<PAGE>

            Saratoga Group, but Saratoga does not elect to cause a Compelled
            Sale pursuant to the foregoing sentence, then Purchaser (or such
            Permitted Transferee) shall have the right to elect to sell to the
            prospective purchaser, as part of the Change of Control Transaction,
            the Pro Rata Portion of Purchaser's (or such Permitted Transferee's)
            Stock (if such right is exercised, a "Co-Sale"). The consideration
            to be received by Purchaser (or such Permitted Transferee) for each
            share of Stock in the Compelled Sale or Co-Sale shall be the same
            consideration per share to be received by the Saratoga Group, and
            the terms and conditions of such sale by Purchaser (or such
            Permitted Transferee) shall be the same as those upon which the
            Saratoga Group sell their shares, except that Purchaser (or such
            other party) shall not be bound by the terms of any indemnity,
            hold-back or escrow given to the prospective purchaser in connection
            with such sale to the extent that such indemnity is not limited in
            value with respect to Purchaser (or such Permitted Transferee) to at
            most the aggregate consideration to be received for his shares of
            the Stock in such sale.

            (b) Notice and Sale Procedures. (i) The Company shall provide
            written notice to Purchaser (or his Permitted Transferee) of any
            proposed Change of Control Transaction, which notice (a "Control
            Transaction Notice") shall: (A) set forth the consideration per
            share to be paid by the prospective purchaser and (B) state whether
            Saratoga is electing pursuant to Section 3.2(a) to cause a Compelled
            Sale. If Saratoga does not elect to cause a Compelled Sale and
            Purchaser (or such Permitted Transferee) desires to cause a Co-Sale
            pursuant to Section 3.2(a), Purchaser (or such Permitted Transferee)
            must give written notice of his election to cause such Co-Sale (a
            "Co-Sale Notice") to Saratoga (or the representative of Saratoga as
            may be designated in the Control Transaction Notice) within ten (10)
            days following the date of the Control Transaction Notice. Within
            ten (10) days following the date of the Control Transaction Notice
            in which Saratoga has elected to cause a Compelled Sale, Purchaser
            (or Permitted Transferee) shall deliver to Saratoga (or such
            designated representative), or in the case of a Co-Sale, the Co-Sale
            Notice shall be accompanied by, the certificates representing the
            shares of the Stock held by Purchaser (or Permitted Transferee) to
            be sold in such Compelled Sale or Co-Sale, together with a suitably
            executed blank stock power and all other documents required to be
            executed in connection with such Change of Control Transaction. In
            the event that Purchaser (or Permitted Transferee) should fail to
            deliver such certificates and other documents as aforesaid, the
            Company shall cause the books and records of the Company to show
            that such shares are bound by the provisions of this Section 3.2 and
            that such shares shall be transferred only to the purchaser
            identified in the Change of Control Notice upon surrender for
            transfer by Purchaser (or any other party) thereof.

            (ii) If, within one hundred twenty (120) days after the Saratoga
            Group gives the notice they have not completed the sale of
            Saratoga's shares described in the notice, the Saratoga Group shall
            return to Purchaser (or such Permitted

                                      -3-
<PAGE>

            Transferee) all certificates representing shares that Purchaser (or
            such Permitted Transferee) delivered for sale pursuant hereto,
            together with any such other documents delivered by Purchaser.

            (iii) Promptly after the consummation of the sale of the shares of
            the Saratoga Group and Purchaser (or Permitted Transferee) pursuant
            to this Section, the Saratoga Group shall remit to Purchaser (or
            Permitted Transferee) the total sales price of the shares of the
            Stock of Purchaser (or Permitted Transferee) sold pursuant thereto,
            and shall furnish such other evidence of the completion and time of
            completion of such sale or other disposition and the terms thereof
            as may be reasonably requested by Purchaser (or Permitted
            Transferee).

4.    PURCHASER'S RIGHTS UPON REPURCHASE.

      At such time as the Company makes available, the consideration for the
Stock to be repurchased in accordance with the provisions of Section 3 of this
Purchase Agreement, then from and after such time the person from whom such
shares are to be repurchased shall no longer have any rights as a holder of such
shares (other than the right to receive payment of such consideration in
accordance with this Purchase Agreement). Such shares shall be deemed to have
been repurchased in accordance with the applicable provisions hereof, whether or
not the certificate(s) therefor have been delivered as required by this Purchase
Agreement.

5.    TRANSFER BY PURCHASER TO CERTAIN TRUSTS.

      Purchaser shall have the right to transfer all or any portion of
Purchaser's interest in the shares of Stock issued under this Purchase Agreement
which have been delivered to Purchaser under the provisions of this Purchase
Agreement, to a trust established by Purchaser for the benefit of Purchaser,
Purchaser's spouse or Purchaser's children, without being subject to the
provisions of Section 3 hereof, provided that the trustee on behalf of the trust
shall agree in writing to be bound by the terms and conditions of this Purchase
Agreement. The transferee shall execute a copy of EXHIBIT A attached hereto and
file the same with the Secretary of the Company.

6.    LEGEND ON SHARES.

      All certificates representing the Stock purchased under this Purchase
Agreement shall, where applicable, have endorsed thereon the following legends

            WRITTEN REQUEST TO THE SECRETARY OF THE COMPANY BY THE HOLDER OF
            SHARES REPRESENTED BY THIS CERTIFICATE.

            OF ANY STATE, AND MAY BE OFFERED AND SOLD ONLY IF REGISTERED AND
            QUALIFIED PURSUANT TO THE RELEVANT PROVISIONS OF FEDERAL AND STATE
            SECURITIES LAWS OR IF THE COMPANY IS PROVIDED AN OPINION OF COUNSEL,
            SATISFACTORY TO THE COMPANY AND ITS COUNSEL, THAT REGISTRATION AND
            QUALIFICATION UNDER FEDERAL AND STATE SECURITIES LAWS IS NOT
            REQUIRED."

7.    PURCHASER'S INVESTMENT REPRESENTATIONS.

      This Purchase Agreement is made with Purchaser in reliance upon
Purchaser's representation to the Company, which by Purchaser's acceptance
hereof Purchaser confirms, that the Stock which Purchaser will receive will be
acquired with Purchaser's own funds for investment for an indefinite period for
Purchaser's own account, not as a nominee or agent, and not with a view to the
sale or distribution of any part thereof, and that Purchaser has no present
intention of selling, granting participation in, or otherwise distributing the
same, but subject, nevertheless, to any requirement of law that the disposition
of Purchaser's property shall at all times be within Purchaser's control. By
executing this Purchase Agreement, Purchaser further represents that Purchaser
does not have any contract, understanding or agreement with any person to sell,
transfer, or grant participation, to such person or to any third person, with
respect to any of the Stock.

      Purchaser understands that the Stock will not be registered or qualified
under federal or state securities laws on the ground that the sale provided for
in this Purchase Agreement is exempt from registration or qualification under
federal or state securities laws and that the Company's reliance on such
exemption is predicated on Purchaser's representations set forth herein.

      Purchaser agrees that in no event will Purchaser make a disposition of any
of the Stock (including a disposition under Section 5 of this Purchase
Agreement), unless and until (i) Purchaser shall have notified the Company of
the proposed disposition and shall have furnished the Company with a statement
of the circumstances surrounding the proposed disposition and (ii) Purchaser
shall have furnished the Company with an opinion of counsel satisfactory to the
Company to the effect that (A) such disposition will not require registration or
qualification of such Stock under federal or state securities laws or (B)
appropriate action necessary for compliance with the federal or state securities
laws has been taken or (iii) the Company shall have waived, expressly and in
writing, its rights under clauses (i) and (ii) of this section.

      With respect to a transaction occurring prior to such date as the Stock is
covered by a valid federal registration statement, this subsection shall apply
unless the transaction is covered

                                      -5-
<PAGE>

by Rule 701 under the Securities Act of 1933, as amended (the "Securities Act")
or another exemption. In connection with the investment representations made
herein, Purchaser represents that Purchaser is able to fend for himself or
herself in the transactions contemplated by this Purchase Agreement, has such
knowledge and experience in financial and business matters as to be capable of
evaluating the merits and risks of Purchaser's investment, has the ability to
bear the economic risks of Purchaser's investment and has been furnished with
and has had access to such information as would be made available in the form of
a registration statement together with such additional information as is
necessary to verify the accuracy of the information supplied and to have all
questions answered by the Company.

      Purchaser understands that if a registration statement covering the Stock
(or a filing pursuant to the exemption from registration under Regulation A of
the Securities Act) under the Securities Act is not in effect when Purchaser
desires to sell the Stock, Purchaser may be required to hold the Stock for an
indeterminate period. Purchaser also acknowledges that Purchaser understands
that any sale of the Stock which might be made by Purchaser in reliance upon
Rule 144 under the Securities Act may be made only in limited amounts in
accordance with the terms and conditions of that Rule.

8.    NO DUTY TO TRANSFER IN VIOLATION HEREUNDER.

      The Company shall not be required (a) to transfer on its books any shares
of Stock of the Company which shall have been sold or transferred in violation
of any of the provisions set forth in this Purchase Agreement or (b) to treat as
owner of such shares or to accord the right to vote as such owner or to pay
dividends to any transferee to whom such shares shall have been so transferred.

9.    RIGHTS OF PURCHASER.

      Except as otherwise provided herein, Purchaser shall, during the term of
this Purchase Agreement, exercise all rights and privileges of a stockholder of
the Company with respect to the Stock.

10.   OTHER NECESSARY ACTIONS.

      The parties agree to execute such further instruments and to take such
further action as may reasonably be necessary to carry out the intent of this
Purchase Agreement.

11.   NOTICE.

      Any notice required or permitted hereunder shall be given in writing and
shall be deemed effectively given upon the earliest of personal delivery,
receipt or the third full day following deposit in the United States Post Office
with postage and fees prepaid, addressed to the other party hereto at the
address last known or at such other address as such party may designate by 10
days' advance written notice to the other party hereto.

12.   SUCCESSORS AND ASSIGNS.

      This Purchase Agreement shall inure to the benefit of the successors and
assigns of the Company and, subject to the restrictions on transfer herein set
forth, be binding upon Purchaser and Purchaser's heirs, executors,
administrators, successors and assigns. No waiver of any breach or condition of
this Purchase Agreement shall be deemed to be a waiver of any other or
subsequent breach or condition, whether of a like or different nature.

13.   APPLICABLE LAW.

      This Purchase Agreement shall be governed by, and construed in accordance
with, the laws of the State of Ohio, as such laws are applied to contracts
entered into and performed in such state.

14.   NO FEDERAL OR OTHER STATE REGISTRATION.

AGREEMENT HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 OR THE
SECURITIES LAW OF ANY STATE AND THE ISSUANCE OF SUCH SECURITIES OR THE PAYMENT
OR RECEIPT OF ANY PART OF THE CONSIDERATION THEREFOR PRIOR TO SUCH REGISTRATION

REGISTRATION OR QUALIFICATION. THE RIGHTS OF ALL PARTIES TO THIS PURCHASE
AGREEMENT ARE EXPRESSLY CONDITIONED UPON SUCH REGISTRATION OR QUALIFICATION
BEING OBTAINED, UNLESS THE SALE IS SO EXEMPT.

15.   NO ORAL MODIFICATION.

writing and signed by the parties hereto.

16.   ENTIRE AGREEMENT.

      This Purchase Agreement constitutes the entire complete and final
agreement between the parties hereto with regard to the subject matter hereof.
