The Company may include Common Stock other than Registrable Securities in a Demand Registration for any accounts on the terms provided below and, if such Demand Registration is an underwritten offering, only with the consent of the managing underwriters of such offering. If the managing underwriters of the requested Demand Registration advise the Company and the Voting Trust Holders that elected to participate in the Demand Request that in their opinion the number of shares of Common Stock proposed to be included in the Demand Registration exceeds the number of shares of Common Stock that can be sold in such underwritten offering without materially delaying or jeopardizing the success of the offering (including the price per share of the Common Stock proposed to be sold in such underwritten offering), the Company shall include in such Demand Registration (i) first, the number of shares of Registrable Securities which the Voting Trust Holders have elected to include in the Demand Request, and (ii) second, the number of shares of Common Stock proposed to be included therein by any other Persons (including Common Stock to be sold for the account of the Company) allocated among such Persons in such manner as the Company may determine.

(d)               Restrictions on Demand Registrations.

Notwithstanding the foregoing, the Company shall not be obligated to take any action that would violate any lockup or similar restriction relating to any Demand Registration or underwritten Shelf Takedown then in effect.

(e)               Selection of Underwriters. If any of the Registrable Securities covered by a Demand Registration is to be sold in an underwritten offering, the Company in consultation with the Trustees shall select the managing underwriter or underwriters to administer the offering.

Following the Form S-3 Eligibility Date, any Voting Trust Holder shall be entitled, at any time and from time to time when an S-3 Registration Statement is effective and until the Termination Date, to use an S-3 Registration Statement to transfer all or a portion of such Voting Trust Holder’s Registrable Securities in an unrestricted number of brokered transactions.

(f)                Priority on Shelf Takedowns. The Company may include Common Stock other than Registrable Securities in a Shelf Takedown for any accounts with the consent of the managing underwriters of such offering as provided herein. If the managing underwriters of the requested Shelf Takedown advise the Company and the Voting Trust Holders that in their opinion the number of shares of Common Stock proposed to be included in the Shelf Takedown exceeds the number of shares of Common Stock that can be sold in such offering without materially delaying or jeopardizing the success of the offering (including the price per share of the Common Stock proposed to be sold in such offering), the Company shall include in such Shelf Takedown (i) first, the number of shares of Common Stock that the Voting Trust Holders who have elected to sell shares in such Shelf Takedown propose to sell, and (ii) second, the number of shares of Common Stock proposed to be included therein by any other Persons (including Common Stock to be sold for the account of the Company) allocated among such Persons in such manner as the Company may determine. If the number of shares of Common Stock that can be sold is less than or equal to the number of shares of Registrable Securities proposed to be included in the Shelf Takedown pursuant to clause (i) above, the amount of Common Stock to be so sold shall be allocated to such Voting Trust Holders pro rata on the basis of the number of shares of Common Stock that each such Voting Trust Holder proposes to sell or as such Voting Trust Holders and the Company may otherwise agree.

Any period during which the Company has delayed a filing or an offering pursuant to this Section 4 is herein called a “Suspension Period.” In no event shall any Suspension Period exceed sixty (60) days, and the number of days covered by any one or more Suspension Periods shall not exceed one hundred twenty (120) days in the aggregate during any rolling period of three hundred sixty-five (365) days. If pursuant to this Section 4 the Company delays a Demand Registration requested by any Voting Trust Holders, such Voting Trust Holders shall be entitled to withdraw such request and, if so withdrawn, such request shall not count against the limitation on the number of such registrations set forth in Section 2(b). If pursuant to this Section 4 the Company withdraws an S-3 Registration Statement requested by any Voting Trust Holders, the Voting Trust Holders shall be entitled to make a further request for an S-3 Registration pursuant to this Agreement. The Company shall provide prompt written notice to the Voting Trust Holders of Registrable Securities covered by the applicable registration statement of the commencement and termination of any Suspension Period (and any withdrawal of a registration statement pursuant to this Section 4), but shall not be obligated under this Agreement to disclose the reasons therefor. The Voting Trust Holders shall keep the existence of each Suspension Period confidential and refrain from making offers and sales of Registrable Securities (and direct any other Persons making such offers and sales to refrain from doing so) during each Suspension Period.

A “full trading day” after an earnings release means at least one full-day trading session on the Nasdaq Global Select Market shall have elapsed after the public issuance of such earnings release. Notwithstanding this Section 4(b), but subject to the other provisions hereof, Registrable Securities may be offered and sold during a Blackout Period if such offers and sales are made pursuant to a Rule 10b5-1 Plan that has been established outside a Blackout Period.

(ii)              During any Blackout Period, the Company shall not be obligated to file or amend any Registration Statement in connection with a Demand Registration or an S-3 Registration or effect, or take any action to effect, any underwritten offering or other offering of Registrable Securities pursuant to a Demand Registration or an S-3 Registration.

(b)               The Company shall use reasonable best efforts to file all reports required to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted by the SEC thereunder and will take such further action as the Trustees shall reasonably request, all to the extent required to enable the Voting Trust Holders to be eligible to sell Registrable Securities pursuant to Rule 144 under the Securities Act prior to the Termination Date.  The Company shall use its reasonable best efforts to prevent the issuance of any stop order or other suspension of effectiveness of any Registration Statement, or the suspension of the qualification of any Registrable Securities for sale in any jurisdiction and, if such an order or suspension is issued, to obtain the withdrawal of such order or suspension as promptly as practicable and to notify the Trustees and the managing underwriter, if any, of the issuance of such order and the resolution thereof or its receipt of actual notice of the initiation or threat of any proceeding for such purpose.

(c)               The Company may require any Participating Voting Trust Holders and each distributor of Registrable Securities as to which any registration is being effected to furnish to the Company any other information regarding such Person and the distribution of such securities as the Company may from time to time reasonably request.

(d)               Each Participating Voting Trust Holder agrees by having its stock treated as Registrable Securities hereunder that, upon being advised in writing by the Trustees of the occurrence of an event pursuant to Section 5(a)(vi), such Participating Voting Trust Holder will immediately discontinue (and direct any other Persons making offers and sales of Registrable Securities to immediately discontinue) offers and sales of Registrable Securities until it is advised in writing by the Company, including through the Trustees, that the use of the Prospectus may be resumed and is furnished with a supplemented or amended Prospectus as contemplated by Section 5(a)(vi), and, if so directed by the Company, including through the Trustees, such Participating Voting Trust Holder will deliver to the Company all copies, other than permanent file copies then in such Participating Voting Trust Holders’ possession, of the Prospectus covering such Registrable Securities current at the time of receipt of such notice.

Section 6.                Registration Expenses.

(a)               All of the Company’s expenses incident to any Demand Registration or S-3 Registration, including all expenses incident to the Company’s performance of or compliance with this Agreement, all registration and filing fees, fees and expenses of compliance with securities or blue sky laws, Financial Industry Regulatory Authority fees, listing application fees, printing expenses, transfer agent’s and registrar’s fees, cost of distributing Prospectuses in preliminary and final form as well as any supplements thereto, and fees and disbursements of counsel for the Company and all independent certified public accountants and other Persons retained by the Company (all such expenses being herein called “Registration Expenses”) (but not including any underwriting discounts or commissions attributable to the sale of Registrable Securities or fees and expenses of counsel representing any underwriters or other distributors), shall be borne by the Company.

(b)               The obligation of the Company to bear the expenses described in Section 6(a) shall apply irrespective of whether a registration, once properly demanded or requested, if applicable, becomes effective, is withdrawn or suspended, is converted to another form of registration and irrespective of when any of the foregoing shall occur; provided, however, that Registration Expenses for any Registration Statement withdrawn solely at the request of any Voting Trust Holders (unless withdrawn following commencement of a Suspension Period pursuant to Section 4) shall be borne by such Voting Trust Holders.

Section 7.                Indemnification.

(a)               The Company shall indemnify, to the fullest extent permitted by law, the Trustees, the Voting Trust Holders and each Person who controls the Voting Trust Holders (within the meaning of the Securities Act) against all losses, claims, damages, liabilities, judgments, costs (including reasonable costs of investigation) and expenses (including reasonable and documented attorneys’ fees) arising out of or based upon any untrue or alleged untrue statement of a material fact contained in any Registration Statement or Prospectus or any amendment thereof or supplement thereto or arising out of or based upon any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as (i) the same are made in reliance and in conformity with information furnished in writing to the Company by the Trustees, the Voting Trust Holders or the underwriters expressly for use therein or (ii) the same are corrected in an amendment or supplement to the Registration Statement or Prospectus and the Trustees, the Voting Trust Holders or any Person who controls the Voting Trust Holders thereafter fails to deliver or cause to be delivered such Registration Statement or Prospectus as so amended or supplemented prior to or concurrently with the Registrable Securities to the Person asserting such loss, claim, damage, liability, judgement cost or expense after the Company has furnished the Trustees, the Voting Trust Holders or such Person who controls the Voting Trust Holders such Registration Statement or Prospectus as so amended or supplemented. In connection with an underwritten offering in which any Voting Trust Holders participate conducted pursuant to a registration effected hereunder, the Company shall indemnify each participating underwriter and each Person who controls such underwriter (within the meaning of the Securities Act) to the same extent as provided above (including the exceptions thereto as applicable to the underwriters) with respect to the indemnification of the Voting Trust Holders, provided, however, that this sentence shall apply only if (based on the current market prices immediately prior thereto) the number of shares of Registrable Securities to be sold in the offering would yield gross proceeds to the Voting Trust Holders of at least the Minimum Amount (or if the Company otherwise approves the offering for purposes of this Section 7).

(b)               In connection with any Registration Statement in which any Voting Trust Holders are participating, such Voting Trust Holders shall furnish to the Company in writing such information and certificates as the Company reasonably requests for use in connection with any such Registration Statement or Prospectus, or amendment or supplement thereto, and shall indemnify, to the fullest extent permitted by law, the Company, its officers and directors and each Person who controls the Company (within the meaning of the Securities Act) against all losses, claims, damages, liabilities, judgments, costs (including reasonable costs of investigation) and expenses (including reasonable attorneys’ fees) arising out of or based upon any untrue or alleged untrue statement of material fact contained in the Registration Statement or Prospectus, or any amendment or supplement thereto or arising out of or based upon any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that the same are made in reliance and in conformity with information furnished in writing to the Company by such Voting Trust Holders expressly for use therein.

(c)               Any Person entitled to indemnification hereunder shall (i) give prompt written notice to the indemnifying Person of any claim with respect to which it seeks indemnification and (ii) permit such indemnifying Person to assume the defense of such claim with counsel reasonably satisfactory to the indemnified Person. Failure so to notify the indemnifying Person shall not relieve it from any liability that it may have to an indemnified Person otherwise than under this Section 7. If such defense is assumed, the indemnifying Person shall not be subject to any liability for any settlement made by the indemnified Person without its consent (but such consent will not be unreasonably withheld). An indemnifying Person who is entitled to, and elects to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel (in addition to one local counsel) for all Persons indemnified by such indemnifying Person with respect to such claim (and all other claims arising out of the same circumstances), unless in the reasonable judgment of any indemnified Person there may be one or more legal or equitable defenses available to such indemnified Person which are in addition to or may conflict with those available to another indemnified Person with respect to such claim, in which case such maximum number of counsel for all indemnified Persons shall be two rather than one). Failure to give prompt written notice shall not release the indemnifying Person from its obligations hereunder. The indemnifying Person shall not consent to the entry of any judgment or enter into or agree to any settlement relating to a claim or action for which any indemnified Person would be entitled to indemnification by any indemnifying Person hereunder unless such judgment or settlement includes as an unconditional term the giving, by all relevant claimants and plaintiffs to such indemnified Person, a release, satisfactory in form and substance to such indemnified Person, from all liabilities in respect of such claim or action for which such indemnified Person would be entitled to such indemnification. The indemnifying Person shall not be liable hereunder for any amount paid or payable or incurred pursuant to or in connection with any judgment entered or settlement effected with the consent of an indemnified Person unless the indemnifying Person has also consented to such judgment or settlement.

(d)               The indemnification and contribution provided for under this Agreement are in addition to any other liability that the indemnifying Persons may otherwise have to the Indemnified persons and shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified Person or any officer, director or controlling Person of such indemnified Person and shall survive the transfer of securities and the Termination Date but only with respect to offers and sales of Registrable Securities made before the Termination Date, and offers and sales of Registrable Securities made pursuant to a Shelf Takedown that has been priced by not completed prior to the Termination Date.

(e)               If the indemnification provided for in or pursuant to this Section 7 is due in accordance with the terms hereof, but is held by a court to be unavailable or unenforceable in respect of any losses, claims, damages, liabilities or expenses referred to herein, then each applicable indemnifying Person, in lieu of indemnifying such indemnified Person, shall contribute to the amount paid or payable by such indemnified Person as a result of such losses, claims, damages, liabilities or expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying Person on the one hand and of the indemnified Person on the other in connection with the statements or omissions which result in such losses, claims, damages, liabilities or expenses as well as any other relevant equitable considerations. The relative fault of the indemnifying Person on the one hand and of the indemnified Person on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the indemnifying Person or by the indemnified Person, and by such Person’s relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Voting Trust Holders agree that it would not be just and equitable if contribution pursuant to this Section 7(e) were determined by pro rata allocation (even if the Voting Trust Holders or any underwriters or all of them were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this paragraph. The amount paid or payable by an indemnified Person as a result of the losses, claims, damages, liabilities or expenses referred to herein shall be deemed to include any reasonable and documented legal or other fees or expenses reasonably incurred by such indemnified in connection with investigating or, except as provided in Section 7(c), defending any such action or claims. Notwithstanding the provisions of this Section 7(e), no Voting Trust Holder shall be required to contribute an amount greater than the proceeds (net of any underwriting discounts and commission) received by such Voting Trust Holder with respect to the sale of any Registrable Securities. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act ) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. The Voting Trust Holders’ obligations in this Section 7(e) to contribute shall be several and not joint in proportion to the amount of Registrable Securities registered by them.

Section 8.                Participation in Offerings.

No Person (including any Voting Trust Holder) may participate in any offering pursuant to a registration effected hereunder, or cause the Company to effect any Demand Registration or S-3 Registration, unless such Person (a) has executed the joinder agreement set forth in Exhibit A and, (b) in the case of any underwritten offering pursuant to a registration effected hereunder, (i) agrees to sell such Person’s securities on the basis provided in any underwriting arrangements approved by the Voting Trust Holders, in the case of any underwritten offering pursuant to a Demand Registration or any underwritten Shelf Takedown, or by the Company, in any other case, and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements, lockups and other documents required under the terms of such underwriting arrangements.

Section 9.                Miscellaneous.

(a)               Notices. Unless otherwise provided in this Agreement, all notices and other communications hereunder shall be in writing, shall reference this Agreement and shall be deemed to have been duly given when (i) delivered, (ii) sent by facsimile or electronic mail or (iii) deposited in the United States mail or private express mail, postage prepaid.

(j)                 Amendments. No provisions of this Agreement shall be deemed waived, amended, supplemented or modified, unless such waiver, amendment, supplement or modification is in writing and signed by the Company and the Trustees.
