(c)                                   Issuer’s Right to Defer Registration .  If the Issuer is requested to effect a Demand Registration and the Issuer furnishes to the Stockholders requesting such registration a copy of a resolution of the Board certified by the secretary of the Issuer stating that in the good faith judgment of the Board it would be adverse to the Issuer and its securityholders for such registration statement to be filed on or before the date such filing would otherwise be required hereunder, the Issuer shall have the right to defer such filing for a period of not more than 90 days after receipt of the request for such registration from such Stockholders, provided, however, that the Issuer shall not utilize this right more than once in any twelve month period.

(b)                                  Underwriter’s Cutback .  Notwithstanding the foregoing, if a Registration pursuant to this Section 4 involves an Underwritten Offering and the managing underwriter or underwriters of such proposed Underwritten Offering delivers an opinion to the Issuer that the total or kind of securities which such Holders and any other Persons intend to include in such offering would be reasonably likely to adversely affect the price, timing or distribution of the securities offered in such offering, then the Issuer shall include in such Registration (i) first, 100% of the securities the Issuer, or the Person initiating such Registration, proposes to sell, (ii) second, if the Registration is being initiated by a Person other than the Issuer, 100% of the securities the Issuer proposes to sell, and (iii) third, to the extent of the amount of securities which all other Holders have requested to be included in such Registration, which, in the opinion of the managing underwriter or underwriters, can be sold without such adverse effect referred to above, such amount to be allocated pro rata among the Holders which have requested to be included in such Piggyback Registration based upon the relative proportionate total holdings of

6

Registrable Securities.  All Holders proposing to distribute their securities through such underwriting will enter into an underwriting agreement in customary form with the managing underwriter or underwriters selected for such underwriting by the Issuer.  Notwithstanding the foregoing, with respect to the underwriting agreement or any other documents reasonably required under such agreement, (i) no Holder shall be required to make any representation or warranty with respect to or on behalf of the Issuer or any other stockholder of the Issuer, and (ii) the liability of any Holder shall be limited as provided in Section 8(b) hereof.  If any Holder disapproves of the terms of such underwriting, such Holder may elect to withdraw therefrom by written notice to the Issuer and the underwriter.

(c)                                   Expenses .  The Issuer shall pay all Registration Expenses in connection with each registration of Registrable Securities requested pursuant to this Section 4.

(d)                                  Issuer’s Control .  The Issuer may decline to file a Registration Statement after giving the Piggyback Notice, or withdraw a Registration Statement after filing and after such Piggyback Notice, but prior to the effectiveness of the Registration Statement, provided that the Issuer shall promptly notify each Holder in writing of any such action and provided further that the Issuer shall bear all reasonable expenses incurred by such Holder or otherwise in connection with such withdrawn Registration Statement.

5.                                       Lock-Up Agreement .

(a)                                   Restrictions on Public Sale by Holders of Registrable Securities .  Provided that all parties (other than the Issuer) hereto are treated equally and all executive officers and directors of the Issuer are also so bound, each Holder agrees that, if so requested by the Board or any managing underwriter in respect of an Underwritten Offering of the Issuer’s securities, such Holder will not sell, make any short sale of, loan, grant any option for the purchase of, hypothecate, hedge or otherwise transfer or dispose of (other than to donees who agree to be similarly bound) any of the Issuer’s securities, including without limitation shares of Common Stock, options or warrants exercisable for shares of the Issuer’s securities, or any other security convertible into or exchangeable for shares of the Issuer’s securities (other than as part of such underwritten public offering), (i) during a period not to exceed 180 days following the effective date of the initial registration statement of the Issuer filed under the Securities Act (or such shorter period as the Issuer or managing underwriter may authorize) and (ii) during a period not to exceed 90 days following the effective date of a registration statement other than the initial registration statement (or such shorter period as the Issuer or managing underwriter may authorize) (each, a “ Stand-Off Period ”).  Each Holder agrees to execute and deliver a lock up agreement as may be reasonably requested by the Issuer and/or managing underwriter consistent with the foregoing obligations.  In order to enforce the foregoing covenant, the Issuer may impose stock transfer restrictions with respect to the securities (including any Registrable Shares) of each Holder until the end of the applicable Stand-Off Period.

Notwithstanding the foregoing, the obligations described in this Section 5(a) shall not apply to a registration relating solely to employee benefit plans on Form S-1 or Form S-8 or similar forms which may be promulgated in the future, or a registration relating solely to an SEC Rule 145 transaction on Form S-4 or similar forms which may be promulgated in the future
