                      ADVANCED LIGHTING TECHNOLOGIES, INC.

                         Common Stock Purchase Agreement

      THIS AGREEMENT is dated as of July 27, 2005, between ADVANCED LIGHTING
TECHNOLOGIES, INC. (the "Company"), and Sabu Krishnan ("Purchaser").

                              W I T N E S S E T H:

      WHEREAS, the Company has given Purchaser an award attached hereto as Annex
1 (the "Award") pursuant to the Company's 2005 Equity Incentive Plan (the
"Plan") and

      WHEREAS, the Award permits the Purchaser to purchase up to 17.985 shares
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
Agreement, the Award and the Plan. Certain capitalized terms used in this
Agreement are defined in the Plan.

      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 17.985
shares [cannot exceed number of Shares above] 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 August 1, 2005, or such
other time and place as may be designated by the Company (the "Closing Date").

      2. REPURCHASE OR FORFEITURE OF UNVESTED STOCK.

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

      In the event the Purchaser ceases to be an Employee of the Company as
defined in the Plan, i.e. terminates service with the Company ("Service") for
any reason, other than a Permitted Reason, all Unvested Stock shall immediately
be forfeited and cancelled without consideration to the Purchaser of any kind.

      If Purchaser ceases to be an Employee of the Company for a Permitted
Reason, the Company shall purchase the Unvested Stock as hereinafter provided.
If any Unvested Stock is subject to a vesting requirement which must be met by a
date certain (the "Vesting Deadline"), and such vesting requirement is not met
on or prior to such date, the Company shall purchase

<PAGE>

such 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. Accordingly, the Company shall be required within 60
days after the (i) termination of Service for a Permitted Reason or (ii) the
Vesting Deadline, as the case may be, to purchase from the Purchaser (A) all
shares of Stock purchased hereunder which have not vested on the date of
termination of Service in accordance with the terms of such vesting schedule in
the Award or (B) all shares of Unvested Stock which could no longer vest after a
Vesting Deadline, as the case may be; provided further, however, if at the time
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 purchase price for such Unvested Stock shall be the Purchase
Price Per Share paid by Purchaser for such shares pursuant to the Award (the
"Purchase Price"). The purchase price shall be paid by check and/or by
cancellation of any indebtedness of Purchaser to the Company. The Company's
rights under this paragraph shall be freely assignable, in whole or in part,
and, following such assignment, such rights will not be limited by any Company
Payment Condition.

      Nothing in this 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
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 four 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 the vesting of a portion of an Award (as defined in
the Award), if Purchaser so requests, the Escrow Agent will deliver to Purchaser
certificates (including any voting trust 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

                                       2
<PAGE>

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

            (b)   Unvested Shares. The Purchaser may not transfer unvested
                  Shares, other than by a Permitted Transfer.

            5.2   After a Major Event. (a) Vested Shares. In the event the
                  Purchaser proposes to sell, pledge or otherwise transfer to a
                  party other than a Permitted Transferee, pursuant to a bona
                  fide purchase offer, any vested Shares acquired under the Plan
                  or any interest in such Shares 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.
                  The 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 the
                  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 vested
                  Shares 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 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.

                                       3
<PAGE>

                  If the Company fails to exercise its Right of First Refusal
                  within 30 days after the date when it received the Transfer
                  Notice, the Purchaser may, not later than 60 days following
                  receipt of the Transfer Notice by the Company, conclude a
                  transfer of the Shares 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 the 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, the Purchaser and the
                  Company (or its assignees) shall consummate the sale of the
                  Shares 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.

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

            5.3 Termination of Service.

                  (a) Prior to a Major Event. (i) Termination for Other than a
                  Permitted Reason. Following the Purchaser's termination of
                  Service for other than a Permitted Reason, as defined in
                  Section 5.3(b) below, the Company shall have the right, but
                  not the obligation, to purchase all or any portion of the
                  vested Shares of the 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 the 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. After any such termination of Service, all unvested
                  Shares of the Purchaser shall be forfeited by the Purchaser
                  and shall be cancelled without payment of any kind.

                  (ii) Termination of Service for A Permitted Reason. (A)
                  Following a termination of Service (I) by the Company for any
                  reason other than "cause," (II) by the Purchaser by
                  resignation with "good reason," (III) death or
                  (IV)"disability," each as defined in the Purchaser's
                  employment contract, or, if the Purchaser does not have such a
                  contract, as defined on Annex 2 to this Agreement (a
                  "Permitted Reason"), the Company shall have the right to
                  purchase all or any portion of the vested Shares of the
                  Purchaser at any time within 12 months following such
                  termination of Service. If such Company purchase would occur
                  before (a) the Purchaser has held the Shares six months or (b)
                  the date which is six months following the vesting of the
                  Shares to be purchased, the repurchase shall occur six months
                  and one day after the later of the purchase of the Shares by
                  the Purchaser or vesting, as the case may be, and for the then
                  current Fair Market Value. 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 the
                  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. The Company
                  will purchase all unvested Shares of such Purchaser within 60
                  days of the Purchaser's such termination of Service; 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.

                  (B) Following any such termination of Service for a Permitted
                  Reason, such Purchaser shall have the right to compel the
                  purchase (a "Vested Put") of that number of vested Shares of
                  Purchaser, at the Fair Market Value at the time of exercise of
                  such right, necessary to make the aggregate consideration, for
                  all unvested Shares purchased pursuant to Subsection
                  5.3(a)(ii)(A) and the vested Shares to be purchased pursuant
                  the Vested Put, would be equal to the total consideration
                  initially paid by such Purchaser for such vested and unvested
                  Shares; provided however, that if the purchase of all such
                  vested and unvested Shares at the prices specified results in
                  aggregate consideration which is less than such total
                  consideration, all vested Shares shall be purchased pursuant
                  to the Vested Put at Fair Market Value. If such Company
                  purchase would occur before (a) the Purchaser has held the
                  Shares six months or (b) the date which is six months
                  following the vesting of the Shares to be purchased, the
                  repurchase shall occur six months and one day after the later
                  of the purchase of the Shares by the Purchaser or vesting, as
                  the case may be, and for the then current Fair Market Value.
                  Such right shall be exercised within twelve (12) months
                  following such termination of Service and the purchase by the
                  Company shall take place within 60 days of such exercise;

                                       5
<PAGE>

                  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.

                  (iii) Company's Rights Assignable. 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 vested Shares following the 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)
                  to require the Purchaser (or his Permitted Transferee) to sell
                  all, or a Pro Rata Portion, of his Shares to the prospective
                  purchaser of the Saratoga Shares (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 Saratoga Group, but Saratoga does
                  not elect to cause a Compelled Sale pursuant to the foregoing
                  sentence, the 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 the Purchaser's (or such Permitted Transferee's)
                  Shares (if such right is exercised, a "Co-Sale"). The
                  consideration to be received by the Purchaser (or such
                  Permitted Transferee) for each Share 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 the Purchaser (or such Permitted Transferee)
                  shall be the same as those upon which the Saratoga Group sell
                  their Shares, except that the Purchaser (or such other party)
                  shall not be bound by the terms of any indemnity, hold-back or
                  escrow given to the purchaser in connection with such sale to
                  the extent that such indemnity is not limited in value with
                  respect to the Purchaser (or such Permitted Transferee) to at
                  most the aggregate consideration to be received for his Shares
                  in such sale.

                  (b) Notice and Sale Procedures. (i) The Company shall provide
                  written notice to the 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

                                       6
<PAGE>

                  to Section 5.4(a) to cause a Compelled Sale. If Saratoga does
                  not elect to cause a Compelled Sale and the Purchaser (or such
                  Permitted Transferee) desires to cause a Co-Sale pursuant to
                  Section 5.4(a), the 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, the Purchaser (or Permitted
                  Transferee) shall deliver to Saratoga (or such designated
                  representative), or in the case of a Co-Sale, the Co-Sale

      9. PURCHASER'S INVESTMENT REPRESENTATIONS.

      This 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 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 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 7 of this 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

                                       8

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 Plan and
Stock thereunder are covered by a valid Form S-8 or similar 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 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.

of Stock of the Company which shall have been sold or transferred in violation

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.

this Agreement, exercise all rights and privileges of a stockholder of the
Company with respect to the Stock.

      Purchaser hereby acknowledges that he or she has been informed that unless

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 the Purchaser,
measured by the excess, if any, of the fair market value of the Shares, at the
time the Company's Unvested Stock Requirement

                                       9

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.

whether of a like or different nature.

      16. APPLICABLE LAW.

VESTING           Your shares will vest, and no longer be subject to the
                  Unvested Stock Agreement pursuant to the Purchase Agreement,
                  as follows:

                  25% of the Shares covered by the Award will vest and no longer
                  be subject to the Unvested Stock Requirement provided that the
                  Company achieves Cumulative Adjusted EBITDA for any 4
                  consecutive fiscal quarters, ending on or before June 30,
                  2007, equal to or greater than $32,977,000; 25% of the Shares
                  covered by the Award will vest and no longer be subject to the
                  Unvested Stock Requirement provided that the Company achieves
                  Cumulative Adjusted EBITDA for any 8 consecutive fiscal
                  quarters, ending on or before June 30, 2008, equal to or
                  greater than $71,075,000; 25% of the Shares covered by the
                  Award will vest and no longer be subject to the Unvested Stock
                  Requirement provided that the Company achieves Cumulative
                  Adjusted EBITDA for any 12 consecutive fiscal quarters, ending

                  significant corporate transaction (such as an acquisition,
                  divestiture or merger) which could reasonably be expected to
                  affect Cumulative Adjusted EBITDA, the amount of Cumulative
                  Adjusted EBITDA required for vesting on any date shall be
                  adjusted, by the Board of Directors of the Company, to reflect
                  the EBITDA expected to be added or lost as a result of such
                  transaction.

                  Notwithstanding the foregoing, in the event of a Change in
                  Control or an Initial Public Offering (each as defined in the
                  Plan) of the Company, your unexpired shares will immediately

                  prior to June 30, 2009 are not less than $90,000,000. If a
                  Change of Control or Initial Public Offering occurs in a

                  at least $90,000,000 being received by Saratoga on or prior to
                  the closing of such transaction, and Saratoga receives or
                  retains securities of the Company or its

                  successors or assigns at or after the closing of such
                  transaction, Saratoga shall provide an escrow of a portion of
                  such securities or other arrangement to assure the
                  participants of the economic benefits of vesting if the
                  aggregate cash amounts received in respect of its Company
                  stock, in such transaction and on liquidation of the
                  securities received or retained by Saratoga results in
                  aggregate amounts received by Saratoga of at least $90,000,000
                  by June 30, 2009.

                  No additional Shares will vest after your employment with the
                  Company or any Affiliate of the Company (including any
                  approved leaves of absence) ("Service") has terminated for any
                  reason.

                  beneficiary but Saratoga Lighting Holdings LLC shall vote all
                  shares in the Voting Trust until the occurrence of a Major
                  Event, at which time the Voting Trust shall terminate.

                  TO THIS AWARD IS EARNED ONLY BY CONTINUING CONSULTANCY OR

                  HEREUNDER). YOU FURTHER ACKNOWLEDGE AND AGREE THAT NOTHING IN

      Set forth below is a brief summary as of the date of the right of some of
the federal tax consequences of purchase and disposition of the Shares.

      THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS
ARE SUBJECT TO CHANGE. PARTICIPANTS SHOULD CONSULT A TAX ADVISER BEFORE
PURCHASING OR DISPOSING OF THE SHARES.

      PURCHASE OF SHARES PRIOR TO VESTING BY CERTAIN PARTICIPANTS

      The Stock Purchase Agreement gives Participants the right to purchase
certain shares which are subject to repurchase by the Company at cost prior to
"vesting." In these situations, an election may be filed by the Participant with
the Internal Revenue Service within 30 days of the purchase of the Shares,
electing pursuant to Section 83(b) of the Code to be taxed currently on the
bargain purchase element on the date of purchase for alternative minimum tax
purposes. EVEN WHERE THERE IS NO BARGAIN ELEMENT FAILURE TO FILE THE 83(b)
ELECTION WILL RESULT IN ALTERNATIVE MINIMUM TAXABLE INCOME MEASURED AND
RECOGNIZED BY PARTICIPANT AT THE TIME OR TIMES ON WHICH THE COMPANY'S REPURCHASE
REQUIREMENT LAPSES. Participant is strongly encouraged to seek the advice of his
or her tax consultants in connection with the purchase of the Shares and the
advisability of filing of the election under Section 83(b) and similar tax
provisions. A form of Election under Section 83(b) is attached to the Stock
Purchase Agreement as Exhibit B for reference.

      THE TAX CONSEQUENCES OF THE PURCHASE AND SALE OF COMMON SHARES AND THE
TERMINATION OF COMPANY REPURCHASE RIGHTS FOR UNVESTED SHARES, MAY DIFFER
DEPENDING UPON THE CIRCUMSTANCES OF EACH PARTICIPANT, THE TERMS OF THE AWARD AND
THE TIMING OF ANY EXERCISE OR SALE. PARTICIPANTS ARE ADVISED TO SEEK INDEPENDENT
TAX ADVICE TO MAKE SURE THEY UNDERSTAND THE INCOME TAX CONSEQUENCES OF ANY
AWARD.
