REGISTRATION RIGHTS

Section 2.01          Demand For Registration; Underwritten Offering.

(a)        Requests for Registration.  Subject to the blackout provisions contained in Section 2.06 and the limitations set forth in this Section 2.01, a Holder or group of Holders (such Holder or group of Holders, the “Initiating Holder(s)”) shall have the right to require the Company to effect a registration with respect to Registrable Securities beneficially owned by such Initiating Holder(s) for an underwritten registration (which, for the avoidance of doubt, may be pursuant to a Shelf Registration Statement as determined by the Initiating Holder(s)) under the Securities Act (a “Registration Request”) by delivering a written request therefor (a “Request Notice”) to the Company specifying the number of Registrable Securities to be included in such underwritten registration by the Initiating Holder(s).  In no event shall the Initiating Holder(s) make a Registration Request under this Section 2.01(a) to offer in the aggregate less than Registrable Securities that constitute three percent (3%) of the Company’s outstanding Common Stock as of the date of the Request Notice (the “Request Date”).  As soon as practicable after the receipt of a Registration Request, the Company shall (i) give written notice of such request to all other Holders and (ii) use commercially reasonable efforts to effect the registration (including, without limitation, appropriate qualification under applicable blue sky or other state securities laws and appropriate compliance with applicable regulations issued under the Securities Act and any other governmental requirements or regulations) of the Registrable Securities that have been requested to be registered in the Registration Request or by any other Holder by written notice to the Company given within fifteen (15) Business Days after the date the Company delivered such Holders notice of the Registration Request.  Any registration requested by a Holder or Holders pursuant to this Section 2.01(a) is referred to in this Agreement as a “Demand Registration”.  The Company shall not be obliged under this Section 2.01(a) to effect more than (A) one (1) Demand Registration during any nine-month period or (B) a total of three (3)

3

Demand Registrations on behalf of the Holders.  For the avoidance of doubt, the Company, at its sole option, may elect to utilize an existing Registration Statement for the purpose of registering any Registrable Securities covered by a Demand Registration.

(b)        Underwriting.  Unless effected pursuant to a Shelf Registration Statement, the offering of the Registrable Securities pursuant to such Demand Registration shall be in the form of an underwritten public offering only. The managing underwriter to administer the offering in connection with any such Demand Registration will be chosen by the Company, subject to the prior written consent, not to be unreasonably withheld, conditioned, or delayed, of the Initiating Holder(s).  The Initiating Holder(s) may designate a co-managing underwriter in connection with any such Demand Registration, subject to the prior written consent, not to be unreasonably withheld, conditioned, or delayed, of the Company.   The right of any Participating Holder other than the Initiating Holder(s) to registration pursuant to this Section 2.01 will be conditioned upon such holder agreeing to the method of distribution being proposed by the Initiating Holder(s) and, in the case of an underwritten offering, agreeing to such underwriting and the inclusion of such holder’s Registrable Securities in the underwriting.  If applicable, the Company and the Participating Holder(s) shall enter into an underwriting agreement in customary form with the managing Underwriter, which underwriting agreement shall have substantially the same indemnification provisions as set forth in this Agreement.

(c)        Priority on Demand Registration.  If, in connection with a Demand Registration, the managing Underwriter gives written advice to the Company of an Underwriters’ Maximum Number, then the Company shall so advise all Initiating Holder(s) and the Company will be required to include in such registration only the Underwriters’ Maximum Number, which securities will be so included in the following order of priority: (i) first, Registrable Securities of the Initiating Holder(s), pro rata on the basis of the aggregate number of Registrable Securities owned by all Initiating Holder(s) who have delivered written requests for registration pursuant to this Section 2.01, (ii) second, Registrable Securities of any other Participating Holders, pro rata on the basis of the aggregate number of Registrable Securities owned by all such Participating Holders who have delivered written requests for registration pursuant to this Section 2.01, (iii), third, any shares of Common Stock to be sold by the Company and (iv) fourth, any shares of Common Stock requested to be included pursuant to the exercise of other contractual registration rights granted by the Company, pro rata among such holders (if applicable) on the basis of the aggregate number of securities requested to be included by such holders.

(d)        Effected Demand Registration.  An offering pursuant to Section 2.01(a) shall not be counted as a Demand Registration for purposes of the second to last sentence of Section 2.01(a) unless such offering is completed, except that in the event (i) the Company has made substantial efforts to effect an offering pursuant to a Registration Request and such offering is not completed due to action or non-action of the Holders or (ii) the offering contemplated by a Registration Request does not close within 180 days of the date on which the applicable Registration Statement has been declared effective by the SEC despite the commercially reasonable efforts of the Company, such offering will be so counted as a Demand Registration and the Company shall have no further obligations to effect such offering.

Section 2.02          Piggyback Registration.

(a)        Notice of Piggyback Registration.  If the Company proposes to register any of its equity securities under the Securities Act either for the Company’s own account or for the account of any of its stockholders (other than (A) securities to be issued solely in connection with any acquisition of or business combination with any entity or business, (B) securities issuable solely upon the exercise of stock options, (C) securities issuable solely pursuant to employee benefit plans, (D) securities issuable in connection with an exchange offer, (E) a registration on any registration form which does not permit secondary sales or does not include substantially the same information as would be required to be

4

included in a Registration Statement, or (F) for Initiating Holder(s) pursuant to Section 2.01 hereof entitled to participate in a registration) (each such registration not withdrawn or abandoned prior to the effective date thereof being herein called a “Piggyback Registration”), the Company will give written notice to all Holders of such proposal not later than the earlier to occur of (i) the seventh (7th) Business Day following the receipt by the Company of notice of exercise of any registration rights by any Persons, and (ii) the fifteenth (15th) Business Day prior to the anticipated filing date of such Piggyback Registration.

(b)        Piggyback Rights.  Subject to the provisions contained in Section 2.02(c), the Company will be required to use commercially reasonable efforts to include in each Piggyback Registration such Registrable Securities as requested in a written notice from any Holder delivered to the Company no later than ten (10) Business Days following delivery of the notice from the Company specified in Section 2.02(a).

(c)        Priority on Piggyback Registrations.  If a Piggyback Registration is an underwritten registration, and the managing underwriter shall give written advice to the Company of an Underwriters’ Maximum Number, then securities will be included in the following order of priority: (i) equity securities proposed to be included in such Piggyback Registration by the Company for its own account, or on the account of such holder or holders for whom or for which the registration was originally being effected pursuant to demand or other registration rights, as applicable, and (ii) if the Underwriters’ Maximum Number exceeds the number of securities proposed to be included pursuant to clause (i), then such excess, up to the Underwriters’ Maximum Number, shall be allocated pro rata among any Participating Holders and any holders of other piggyback registration rights on the basis of the number of securities requested to be included therein by each such Holder or other Person.

(d)        Selection of Underwriter(s).  If the Piggyback Registration is proposed to be underwritten, the Company will so advise the Holders in the notice referred to in Section 2.02(a).  In such event, the right of any Holder to registration pursuant to this Section 2.02 will be conditioned upon such holder’s participation in such underwriting and the inclusion of such holder’s Registrable Securities in the underwriting.  The Company, or the holder or holders for whom or for which such registration was originally being effected pursuant to demand or other registration rights, as applicable, shall have the sole right to select the investment banker(s) and managing underwriter(s) in any such underwritten Piggyback Registration.

Section 2.03          Registration Expenses.  In connection with registrations pursuant to Section 2.01 or 2.02 hereof, the Company shall pay the following registration costs and expenses incurred in connection with the registration thereunder (the “Registration Expenses”): (i) registration and filing fees and expenses, including, without limitation, those related to filings with the Commission, (ii) fees and expenses of compliance with state securities or blue sky laws (including reasonable fees and disbursements of counsel in connection with blue sky qualifications of the Registrable Securities), (iii) reasonable processing, duplicating and printing expenses, including, without limitation, expenses of printing any prospectuses or issuer free writing prospectuses reasonably requested by any Participating Holder, (iv)  the Company’s internal expenses (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties, the expense of any liability insurance and the expense of any annual audit or quarterly review), (v) fees and expenses incurred in connection with listing the Registrable Securities for trading on a national securities exchange, including, without limitation, fees and expenses of The New York Stock Exchange, (vi) fees and expenses in connection with the preparation of the registration statement and related documents covering the Registrable Securities, (vii) fees and expenses, if any, incurred with respect to any filing with FINRA, (viii) any documented out-of-pocket expenses of the Underwriter(s) incurred with the approval of the Company, (ix) the cost of providing any CUSIP or other identification numbers for the Registrable Securities, (x) fees

Section 3.01 or 3.02, except to the extent that the Indemnifying Party is prejudiced thereby.  If any such claim or action shall be brought against an Indemnified Party, and it shall notify the Indemnifying Party thereof, the Indemnifying Party shall be entitled to assume the defense thereof with counsel reasonably satisfactory to the Indemnified Party.  After notice from the Indemnifying Party to the Indemnified Party of its election to assume the defense of such claim or action, the Indemnifying Party shall not be liable to the Indemnified Party for any legal or other expenses subsequently incurred by the Indemnified Party in connection with the defense thereof other than reasonable out-of-pocket costs of investigation; provided, that the Indemnified Party shall have the right to employ separate counsel to represent the Indemnified Party who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the Indemnified Party against the Indemnifying Party, but the fees and expenses of such counsel shall be for the account of such Indemnified Party unless (i) the Indemnifying Party and the Indemnified Party shall have mutually agreed to the retention of such counsel or (ii) in the reasonable opinion of counsel to such Indemnified Party representation of both parties by the same counsel would be inappropriate due to actual or potential conflicts of interest between them, it being understood, however, that the Indemnifying Party shall not, in connection with any one such claim or action or separate but substantially similar or related claims or actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (together with appropriate local counsel) at any time for all Indemnified Parties.  No Indemnifying Party shall, without the prior written consent of the Indemnified Party, effect any settlement of any claim or pending or threatened proceeding in respect of which the Indemnified Party is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such settlement includes an unconditional release of such Indemnified Party from all liability arising out of such claim or proceeding.  Whether or not the defense of any claim or action is assumed by the Indemnifying Party, such Indemnifying Party will not be subject to any liability for any settlement made without its written consent.

ARTICLE IV

MISCELLANEOUS

Section 4.01          Holdback.  If requested by the underwriters managing any underwritten offering in which any Registrable Securities are eligible to be sold (without giving effect to any Underwriters’ Maximum Number), without the prior written consent of the underwriter for such offering during the period specified by such underwriter, which period shall not exceed fourteen (14) days prior to or sixty (60) days following the effective date of the applicable registration, each Holder will agree with such underwriter and the other holders of Registrable Securities not to transfer any Common Stock or any other equity securities of the Company.

Section 4.02          Limitations on Transfer.  The provisions of Section 3 of the Stockholder Agreement will apply to any transfers of Registrable Securities pursuant to this Agreement or any registered offering.

Section 4.03          Suspension of Registration Rights and Termination.

(a)        The rights and obligations of the parties under this Agreement shall be suspended and of no force and effect during the period from the date hereof until the initial acquisition by the Cascade Parties (as defined in the Stockholder Agreement) of “beneficial ownership” (as defined in the Stockholder Agreement) of, in the aggregate, fifteen percent (15%) or more of outstanding shares of Common Stock.

11

(b)        The rights granted under this Agreement shall terminate upon the earlier of (i) the termination of the Stockholder Agreement or (ii) the date that the Registrable Securities represent less than two percent (2%) of the then-outstanding Common Stock.

(c)        Notwithstanding anything contained in this Agreement, the rights of the Holders and the obligations of the Company under Article II of this Agreement shall be suspended and of no force and effect in the event and for so long as a Cascade Party (as defined in the Stockholder Agreement) is in breach of the terms and conditions of the Stockholder Agreement.

Section 4.04          Amendment and Modification.  This Agreement may be amended, modified and supplemented, and any of the provisions contained herein may be waived, only by a written instrument signed by the Company and each Holder, provided that the addition of a permitted assign as a Holder hereunder shall not constitute an amendment or modification for purposes of this Section 4.04.

Section 4.05          Assignment; Binding Effect; Entire Agreement.  The rights and obligations hereunder may be assigned in whole or in part by any Holder to a controlled affiliate of such Holder, effective only for so long as such transferee remains a controlled affiliate of a Holder as of the date hereof (a “Permitted Transferee”) without the consent of the Company or the other Holders.  Such assignment shall be effective upon receipt by the Company of (x) written notice from the Holder certifying that the transferee is a Permitted Transferee, stating the name and address of the Permitted Transferee and identifying the amount of Registrable Securities with respect to which the rights under this Agreement are being transferred, and (y) a written agreement from the Permitted Transferee to be bound by all of the terms of this Agreement.  Upon receipt of the documents referenced in (x) and (y) above, the Permitted Transferee shall thereafter be deemed to be a “Holder” for all purposes of this Agreement.  Except as set forth above, this Agreement and the rights and obligations hereunder may not be assigned by any party hereto without the prior written consent of each of the other parties hereto.  This Agreement and all of the provisions hereof shall be binding upon and inure to the benefit of the parties hereto and their respective permitted successors and assigns.  This Agreement sets forth the entire agreement and understanding between the parties as to the subject matter hereof and merges and supersedes all prior discussions, agreements and understandings of any and every nature among them with respect to the subject matter hereof.

Section 4.06          Severability.  In the event that any provision of this Agreement or the application of any provision hereof is declared to be illegal, invalid or otherwise unenforceable by a court of competent jurisdiction, the remainder of this Agreement shall not be affected except to the extent necessary to delete such illegal, invalid or unenforceable provision unless that provision held invalid shall substantially impair the benefits of the remaining portions of this Agreement.

Section 4.07          Notices.  All notices, requests and other communications to any party hereunder shall be in writing (including fax or similar writing) and shall be given to:

12

or such other address or fax number as such party may hereafter specify for the purpose of giving such notice to such party.  Each such notice, request or other communication shall be deemed to have been received (a) if given by fax, when such fax is transmitted to the fax number specified pursuant to this Section 4.07 and appropriate confirmation is received, or (b) if given by any other means, when delivered in person or by overnight courier.

Section 4.08          Headings.  The headings in this Agreement are for convenience of reference only and shall not constitute a part of this Agreement, nor shall they affect their meaning, construction or effect.
