ARTICLE I

REGISTRATION

1.1. Demand Registrations.

(a) Subject to the terms and conditions hereof, solely during any period when the Company is not eligible under Applicable Law to register Registrable Securities on Form S-3 pursuant to Section 1.3, any Holder (“Requesting Stockholders”) shall be entitled to make requests of the Company (each, a “Demand”) for registration under the Securities Act of an amount of Registrable Securities then held by such Requesting Stockholders that equals or is greater than the Registrable Amount (a “Demand Registration”). Thereupon the Company will, subject to the terms of this Agreement, use its reasonable best efforts to effect the registration as promptly as reasonably practicable under the Securities Act of:

(i) the Registrable Securities which the Company has been so requested to register by the Requesting Stockholders for disposition in accordance with the intended method of disposition stated in such Demand;

(ii) all other Registrable Securities which the Company has been requested to register pursuant to Section 1.1(b), but subject to Section 1.1(e); and

(iii) all shares of Company Common Stock which the Company may elect to register in connection with any offering of Registrable Securities pursuant to this Section 1.1, but subject to Section 1.1(e);

all to the extent necessary to permit the disposition (in accordance with the intended methods thereof) of the Registrable Securities and the additional shares of Company Common Stock, if any, to be so registered.

(b) A Demand shall specify (i) the aggregate number of Registrable Securities requested to be registered in such Demand Registration, (ii) the intended method of disposition in connection with such Demand Registration, to the extent then known and (iii) the identity of the Requesting Stockholder(s). Within five (5) Business Days after receipt of a Demand, the Company shall give written notice of such Demand to all other Holders of Registrable Securities. The Company shall include in the Demand Registration covered by such Demand all Registrable Securities with respect to which the Company has received a written request for inclusion therein from the Holder thereof within five (5) Business Days after the Company’s notice required by this paragraph has been given, subject to Section 1.1(e). Each such written request shall comply with the requirements of a Demand as set forth in this Section 1.1(b). The Company shall not be required to effect any Demand Registration within one hundred eighty (180) days after the effective date of a previous Demand Registration and shall not be obligated to effect more than three (3) Demand Registrations pursuant to this Section 1.1.

(c) Demand Registrations shall be on Form S-1 or any similar long-form registration statement that may be available at the time.

(d) The Company shall maintain the effectiveness of a Demand Registration for a period of at least one hundred eighty (180) days or such shorter period in which all Registrable Securities included in such Demand Registration have actually been sold thereunder (provided, that such period shall be extended for a period of time equal to the period the Holder of Registrable Securities refrains from selling any securities included in such registration statement at the request of the Company or the lead managing underwriter(s) pursuant to the provisions of this Agreement). The Company shall not be obligated to effect any Demand Registration (A) within one hundred eighty (180) days of a “firm commitment” Underwritten Offering in which all Holders were offered “piggyback” rights pursuant to Section 1.2 (subject to Section 1.2(b)) and at least 80% of the number of Registrable Securities requested by such Requesting Stockholders to be included in such Demand Registration were included and sold or (B) within one hundred eighty (180) days of the completion of any other Demand Registration (including, for the avoidance of doubt, any Underwritten Offering pursuant to any Shelf Registration Statement).

2

(e) If, in connection with a Demand Registration or Shelf Offering that involves an Underwritten Offering, the lead managing underwriter(s) advise(s) the Company that, in its (their) opinion, the inclusion of all of the securities sought to be registered in connection with such Demand Registration would materially adversely affect the price that will be paid in such offering or the marketability thereof, then the Company shall include in such registration statement only such securities as the Company is advised by such lead managing underwriter(s) can be sold without such adverse effect as follows and in the following order of priority: (i) first pro rata among the Holders that have requested to participate in such Demand Registration based on the relative number of Registrable Securities then held by each such Holder (provided that any Registrable Securities thereby allocated to a Holder that exceed such Holder’s request shall be reallocated among the remaining requesting Holders in like manner); (ii) second, any Existing Registrable Securities or Primary Issuance Funding Securities requested to be registered or sold by the Demand Committee, any securities entitled to Other Registration Rights that are pari passu with the piggyback rights contained in the Existing Registration Rights Agreement requested to be registered by the holders thereof and any securities the Company proposes to register or sell (other than Primary Issuance Funding Securities), ratably among the Company, such participating Covered Persons and the holders of such Other Registration Rights based on the respective amounts of securities the Company has proposed to include, the Demand Committee has requested to include and the holders of such Other Registration Rights have requested to include and (iii) third, all other securities of the Company duly requested to be included in such registration statement by other persons, pro rata on the basis of the amount of such other securities requested to be included or such other allocation method determined by the Company.

(f) The Company shall be entitled to postpone (upon written notice and the delivery of a certificate in accordance with this Section 1.1(f) to the Requesting Stockholders and any other Holders whose Registrable Securities are covered by such Demand pursuant to Section 1.1(b)) the filing or effectiveness of a registration statement for any Demand Registration in the event of a Blackout Period (subject to the conditions of the definition thereof) until the expiration of the applicable Blackout Period. In the event of a Blackout Period, the Company shall deliver to the Requesting Stockholders requesting registration and any other Holders whose Registrable Securities are covered by such Demand pursuant to Section 1.1(b) a certificate signed by either the chief executive officer or the chief financial officer of the Company certifying that, in the good faith judgment of the Company, the conditions described in the definition of Blackout Period are met.

(g) Any time that a Demand Registration or Shelf Offering involves an Underwritten Offering, the Holders who have requested to participate in such Demand Registration or Shelf Offering shall select the investment banker(s) and manager(s) that will serve as managing underwriters (including which such managing underwriters will serve as lead or co-lead) and underwriters with respect to the offering of such Registrable Securities; provided that such investment banker(s) and manager(s) shall be subject to the prior written consent of the Holders of a majority of the Registrable Securities then held by the Company, not to be unreasonably withheld, conditioned or delayed.

1.2. Piggyback Registrations.

(a) Subject to the terms and conditions hereof, whenever the Company proposes to register any Company Common Stock under the Securities Act for its own account or for the account of other persons who are not Holders (other than (i) an Exchange Registration, (ii) a registration statement filed in connection with a Primary Issuance Funding under the Exchange Agreement, (iii) a registration by the Company on Form S-4 or any successor form thereto, (iv) a registration by the Company on Form S-8 or any successor form thereto (v) a registration in connection with any dividend reinvestment plan or similar plans, (vi) a registration in which the only common stock being registered is common stock issuable upon conversion of debt securities also being registered or (vii) pursuant to Section 1.1) (a “Piggyback Registration”), the Company shall give all Holders prompt written notice thereof (but not less than ten (10) Business Days prior to the filing by the Company with the Commission of any registration statement with respect thereto). Such notice (a “Piggyback Notice”) shall specify the number of shares of Company Common Stock proposed to be registered, the proposed date of filing of such registration statement with the Commission, the proposed means of distribution, the proposed managing underwriter(s) (if any) and a good faith estimate by the Company of the proposed minimum offering price of such shares of Company Common Stock, in each case to the extent then known. Subject to Section 1.2(b), the Company shall use reasonable best efforts to include in each such Piggyback Registration all Registrable Securities held by Holders (a “Piggyback Seller”) with respect to which the Company has received written requests (which written requests shall specify the number of Registrable Securities requested to be disposed of by such Piggyback Seller) for inclusion therein within five (5) Business Days after such Piggyback Notice is received by such Piggyback Seller.

(b) If, in connection with a Piggyback Registration that involves an Underwritten Offering, the lead managing underwriter(s) advises the Company that, in its opinion, the inclusion of all the shares of Company Common Stock sought to be included in such Piggyback Registration by (i) the Company, (ii) other Persons who have sought to have shares of Company Common Stock registered in such Piggyback Registration pursuant to rights to demand (other than pursuant to so-called “piggyback” or other incidental or participation rights) such registration (such Person being “Other Demanding Sellers”), (iii) the Piggyback Sellers and (iv) any other proposed sellers of shares of Company Common Stock (such Persons being “Other Proposed Sellers”), as the case may be, would materially adversely affect the price that will be paid in such offering or the marketability thereof, then the Company shall include in the registration statement applicable to such Piggyback Registration only such shares of Company Common Stock as the Company is so advised by such lead managing underwriter(s) can be sold without such an effect, as follows and in the following order of priority:

(i) If the Piggyback Registration relates to an offering for the Company’s own account, then (A) first, such number of shares of Company Common Stock (other than Primary Issuance Funding Securities) to be sold by the Company, (B) second, Registrable Securities of Piggyback Sellers, Existing Registrable Securities and Primary Issuance Funding Securities requested to be registered or sold by the Demand Committee and any Company securities entitled to Other Registration Rights that are pari passu with the rights of the Piggyback Sellers, ratably among the Piggyback Sellers, the participating Covered Persons and the holders of such Other Registration Rights based on the respective amounts of securities requested to be included, (C) third, any securities to be registered or sold for the account of any other persons with such priorities as the Company shall determine; or

4

(ii) if the Piggyback Registration relates to an offering other than for the Company’s own account, then (A) first, such number of shares of Company Common Stock sought to be registered by each Other Demanding Seller, (B) second, Registrable Securities of Piggyback Sellers, any Existing Registrable Securities and Primary Issuance Funding Securities requested to be registered or sold by the Demand Committee, any Company securities entitled to Other Registration Rights that are pari passu with the rights of the Piggyback Sellers and any securities the Company proposes to register or sell (other than Primary Issuance Funding Securities), ratably among the Company, the Piggyback Sellers, such participating Covered Persons and the holders of such Other Registration Rights based on the respective amounts of securities requested to be included, (C) third, other shares of Company Common Stock proposed to be sold by any Other Proposed Sellers.

(c) For clarity, in connection with any Underwritten Offering under this Section 1.2, the Company shall not be required to include the Registrable Securities of a Piggyback Seller in the Underwritten Offering unless such Piggyback Seller accepts the terms of the underwriting as agreed upon between the Company and the lead managing underwriter(s), which shall be selected by the Company or as otherwise specified in the Existing Registration Rights Agreement.

(d) If, at any time after giving written notice of its intention to register any shares of Company Common Stock as set forth in this Section 1.2 and prior to the time the registration statement filed in connection with such Piggyback Registration is declared effective, the Company shall determine for any reason not to register such shares of Company Common Stock, the Company may, at its election, give written notice of such determination to the Piggyback Sellers within five (5) Business Days thereof and thereupon shall be relieved of its obligation to register any Registrable Securities in connection with such particular withdrawn or abandoned Piggyback Registration; provided, that Holders may continue the registration as a Demand Registration pursuant to the terms of Section 1.1.

1.3. Shelf Registration Statement.

(a) The Company shall file, as promptly as reasonably practicable following the date hereof (and, for the avoidance of doubt, shall use reasonable best efforts to cause such filing to occur within ten (10) Business Days of the date hereof (or fifteen (15) Business Days if the Company is a “well know seasoned issuer”)), a registration statement on Form S-3 or any successor form thereto (“Form S-3”) providing for an offering to be made on a continuous basis pursuant to Rule 415 under the Securities Act (a “Shelf Registration Statement”) registering all Registrable Securities then held by the Holders and including a plan and method of distribution substantially in the form of Exhibit A hereto.

(b) The Company will use its reasonable best efforts to cause a Shelf Registration Statement to be effective as of the effective date of the Merger (or as soon as practicable thereafter) and keep a Shelf Registration Statement continuously effective until the earlier of (i) the date on which all Registrable Securities covered by the Shelf Registration Statement have been sold thereunder in accordance with the plan and method of distribution disclosed in the prospectus included in the Shelf Registration Statement, or otherwise cease to be Registrable Securities; and (ii) the date on which this Agreement terminates pursuant to Section 4.1.

5

(c) At any time that a Shelf Registration Statement is effective, if one or more Holders deliver a notice to the Company (a “Take-Down Notice”) stating that such Holder(s) intend to sell a Registrable Amount of Registrable Securities on the Shelf Registration Statement in an Underwritten Offering (such Underwritten Offering, a “Shelf Offering”), the Company shall promptly, and in a manner reasonably agreed with such Holder(s), amend or supplement the Shelf Registration Statement as may be necessary in order to enable such Registrable Securities to be distributed pursuant to the Shelf Offering and take action to sell pursuant to such other means as are set forth in the plan of distribution.

(d) Notwithstanding anything to the contrary contained in this Agreement, the Company shall be entitled, from time to time (subject to the limitations in the definition of Blackout Period), by providing written notice to the Holders whose Registrable Securities are registered under the Shelf Registration Statement, to require such Holders to suspend the use of the prospectus for sales of Registrable Securities under the Shelf Registration Statement during any Blackout Period. In the event of a Blackout Period, the Company shall deliver to such Holders a certificate signed by either the chief executive officer or the chief financial officer of the Company certifying that, in the good faith judgment of the Company, the conditions described in the definition of Blackout Period are met. After the expiration of any Blackout Period and without any further request from a Holder of Registrable Securities, the Company to the extent necessary shall as promptly as reasonably practicable prepare a post-effective amendment or supplement to the Shelf Registration Statement or the prospectus, or any document incorporated therein by reference, or file any other required document so that, as thereafter delivered to purchasers of the Registrable Securities included therein, the prospectus will not include an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

1.4. Withdrawal Rights. Any Holder having notified or directed the Company to include any or all of its Registrable Securities in a registration statement under the Securities Act shall have the right to withdraw any such notice or direction with respect to any or all of the Registrable Securities designated by it for registration by giving written notice to such effect to the Company prior to the effective date of such registration statement. In the event of any such withdrawal, the Company shall not include such Registrable Securities in the applicable registration and such Registrable Securities shall continue to be Registrable Securities for all purposes of this Agreement (subject to the other terms and conditions of this Agreement). No such withdrawal shall affect the obligations of the Company with respect to the Registrable Securities not so withdrawn if any other Holder has requested that Registrable Securities be included in such registration; provided, however, that in the case of a Demand Registration, if such withdrawal shall reduce the number of Registrable Securities sought to be included in such registration below the Registrable Amount, then the Company shall as promptly as practicable give each Holder seeking to register Registrable Securities notice to such effect and, within five (5) Business Days following the mailing of such notice, such Holders still seeking registration shall, by written notice to the Company, elect to register additional Registrable Securities to satisfy the Registrable Amount or elect that such registration statement not be filed or, if theretofore filed, be withdrawn. During such five (5) Business Day period, the Company shall not file such registration statement if not theretofore filed or, if such registration statement has been theretofore filed, the Company shall not seek, and shall use reasonable efforts to prevent, the effectiveness thereof.

1.5. Holdback Agreements. (a) In connection with any Underwritten Offering in which a Holder participates pursuant to Section 1.2, if so requested by the lead managing underwriters, each such Holder agrees to enter into customary agreements, including such customary carve-outs and limitations as any such Holder may reasonably request, restricting the public sale or distribution of equity securities of the Company (including sales pursuant to Rule 144 under the Securities Act) to the extent required in writing by the lead managing underwriter(s) with respect to an applicable Underwritten Offering during the period commencing on the date of the “pricing” of such Underwritten Offering) and continuing for not more than the lesser of (i) the period to which the Company and each of its directors and officers (subject to customary carve-outs and limitations) is restricted and (ii) sixty (60) days after the date of the “final” prospectus (or “final” prospectus supplement if the Underwritten Offering is made pursuant to a Shelf Registration Statement), pursuant to which such Underwritten Offering shall be made, or such shorter period as is required by the lead managing underwriter(s). Any discretionary waiver or termination of the requirements under the foregoing provisions made by the Company or applicable lead managing underwriter(s) shall apply to each Holder on a pro rata basis.

(b) If so requested by the lead managing underwriters in connection with any Underwritten Offering, the Company will not effect, and will cause each of its directors and officers not to effect, any public sale or distribution of any common equity (or securities convertible into or exchangeable or exercisable for common equity) (subject to customary carveouts and limitations), within sixty (60) days or such shorter period as the managing underwriter shall agree to, after the date of such Underwritten Offering, except as may otherwise be agreed between the Company and the lead managing underwriter(s) of such Underwritten Offering, as applicable.

1.6. Registration Procedures.

All fees and expenses incident to the Company’s performance of its obligations under this Article I, including (a) all registration and filing fees, including all fees and expenses of compliance with securities and “blue sky” laws (including the reasonable and documented fees and disbursements of counsel for the underwriters in connection with “blue sky” qualifications of the Registrable Securities pursuant to Section 1.6(a)(v)) and all fees and expenses associated with filings required to be made with FINRA (including, if applicable, the fees and expenses of any “qualified independent underwriter” as such term is defined in FINRA Rule 5121), (b) all printing (including expenses of printing certificates for the Registrable Securities in a form eligible for deposit with the Depository Trust Company and of printing prospectuses if the printing of prospectuses is requested by a Holder) and copying expenses, (c) all messenger, telephone and delivery expenses, (d) all fees and expenses of the Company’s independent certified public accountants and counsel, and (e) reasonable and documented fees and disbursements of one counsel for all Holders whose Registrable Securities are included in a registration statement, which counsel shall be selected by the Holders of a majority of the Registrable Securities being sold in connection therewith, shall be borne solely by the Company whether or not any registration statement is filed or becomes effective. In connection with the Company’s performance of its obligations under this Article I, the Company will pay its internal expenses (including all salaries and expenses of its officers and employees performing legal or accounting duties and the expense of any annual audit) and the expenses and fees for listing the securities to be registered on each securities exchange and included in each established over-the-counter market on which similar securities issued by the Company are then listed or traded. Each Selling Stockholder shall pay its portion of all underwriting discounts and commissions and transfer taxes, if any, relating to the sale of such Selling Stockholder’s Registrable Securities pursuant to any registration.

1.8. Miscellaneous.

(a) Not less than five (5) Business Days before the expected filing date of each registration statement pursuant to this Agreement, the Company shall notify each Holder of Registrable Securities who has timely provided the requisite notice hereunder entitling such holder to register Registrable Securities in such registration statement of the information, documents and instruments from such holder that the Company or any underwriter reasonably requests in connection with such registration statement, including, to the extent applicable, a questionnaire, custody agreement, power of attorney, lock-up letter (not to exceed a 60 days lock-up period) and underwriting agreement (the “Requested Information”). If the Company has not received, on or before the second (2^nd) Business Day before the expected filing date, the Requested Information from such holder, the Company may file the registration statement without including Registrable Securities of such holder. The failure to so include in any registration statement the Registrable Securities of a holder of Registrable Securities (with regard to that registration statement) shall not result in any liability on the part of the Company to such Holder.

(b) The Company shall not grant any demand, piggyback or shelf registration rights, the terms of which conflict with the rights granted to the Holders of Registrable Securities hereunder to any other Person, or enter into any other agreements that conflict with the rights granted to the Holders of Registrable Securities under this Agreement, without the prior written consent of Holders holding a majority of the Registrable Securities then held by all Holders.

(c) The Company will cooperate with the Holders and the managing underwriter(s), if any, to facilitate the timely preparation and delivery of certificates or book entries (which, in either case, shall not bear any restrictive legends) representing Shares to be sold by any Holder pursuant to any registration statement or sold pursuant to Rule 144 under the Securities Act, and enable such shares to be in such denominations and registered in such names as the selling Holders or managing underwriter(s) may request.

1.9. Registration Indemnification.

(a) The Company agrees, without limitation as to time, to indemnify and hold harmless, to the fullest extent permitted by Law, each Selling Stockholder and its Affiliates and their respective officers, directors, members, shareholders, employees, managers, partners and agents and each Person who controls (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act) such Selling Stockholder or such other indemnified Person and the officers, directors, members, shareholders, employees, managers, partners, accountants, attorneys and agents of each such controlling Person, from and against all losses, claims, damages, liabilities, costs, expenses (including reasonable expenses of investigation and reasonable attorneys’ fees and expenses) and amounts paid in settlement (collectively, the “Losses”), as incurred, arising out of, caused by, resulting from or relating to any untrue statement (or alleged untrue statement) of a material fact contained in any registration statement, prospectus or preliminary prospectus or Free Writing Prospectus or any amendment or supplement thereto or any omission (or alleged omission) of a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, preliminary prospectus, Free Writing Prospectus or any amendment or supplement thereto, in light of the circumstances under which they were made) not misleading, except insofar as the same are caused by any information furnished in writing to the Company by any Selling Stockholder expressly for use therein.

(b) In connection with any registration statement in which a Selling Stockholder is participating, without limitation as to time, each such Selling Stockholder shall, severally and not jointly, indemnify the Company, its directors, officers, stockholders, employees, managers, partners and agents and each Person who controls (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act) the Company, from and against all Losses, as incurred, arising out of, caused by, resulting from or relating to any untrue statement (or alleged untrue statement) of material fact contained in the registration statement, prospectus or preliminary prospectus or Free Writing Prospectus or any amendment or supplement thereto or any omission (or alleged omission) of a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, preliminary prospectus, Free Writing Prospectus or any amendment or supplement thereto, in light of the circumstances under which they were made) not misleading, in each case solely to the extent, but only to the extent, that such untrue statement or omission is made in such registration statement, prospectus or preliminary prospectus or Free Writing Prospectus or any amendment or supplement thereto in reliance upon and in conformity with written information regarding such Selling Stockholder furnished to the Company by such Selling Stockholder expressly for inclusion in such registration statement, prospectus or preliminary prospectus or Free Writing Prospectus or any amendment or supplement thereto. Notwithstanding the foregoing, no Selling Stockholder shall be liable under this Section 1.9(b) for amounts in excess of the net proceeds received by such holder in the offering giving rise to such liability.

13

(c) Any Person entitled to indemnification hereunder shall give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification; provided, however, the failure to give such notice shall not release the indemnifying party from its obligation, except to the extent that the indemnifying party has been actually and materially prejudiced by such failure to provide such notice on a timely basis.

(d) In any case in which any such action is brought against any indemnified party, and it notifies an indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein, and, to the extent that it may wish, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof and acknowledging the obligations of the indemnifying party with respect to such proceeding, the indemnifying party will not (so long as it shall continue to have the right to defend, contest, litigate and settle the matter in question in accordance with this paragraph) be liable to such indemnified party hereunder for any legal or other expense subsequently incurred by such indemnified party in connection with the defense thereof (unless (i) such indemnified party reasonably objects to such assumption on the grounds that there are defenses available to it which are different from or in addition to the defenses available to such indemnifying party and, as a result, a conflict of interest exists or (ii) the indemnifying party shall have failed within a reasonable period of time to assume such defense and the indemnified party is or would reasonably be expected to be materially prejudiced by such delay, in either of which events the indemnified party shall be promptly reimbursed by the indemnifying party for the reasonable fees and expenses incurred in connection with retaining one separate legal counsel (for the avoidance of doubt, for all indemnified parties in connection therewith)). For the avoidance of doubt, notwithstanding any such assumption by an indemnifying party, the indemnified party shall have the right to employ separate counsel in any such matter and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such indemnified party except as provided in the previous sentence. An indemnifying party shall not be liable for any settlement of an action or claim effected without its consent (which consent shall not be unreasonably withheld, conditioned or delayed). No matter shall be settled by an indemnifying party without the consent of the indemnified party (which consent shall not be unreasonably withheld, conditioned or delayed), unless such settlement (x) includes as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation, (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any indemnified party and (z) is settled solely for cash for which the indemnified party would be entitled to indemnification hereunder.

(e) The indemnification provided for under this Agreement shall survive the sale of the Registrable Securities and the termination of this Agreement.

(f) If recovery is not available under the foregoing indemnification provisions for any reason or reasons other than as specified therein, any Person who would otherwise be entitled to indemnification by the terms thereof shall nevertheless be entitled to contribution with respect to any Losses with respect to which such Person would be entitled to such indemnification but for such reason or reasons, in such proportion as is appropriate to reflect the relative fault of the indemnifying party, on the one hand, and such indemnified party, on the other hand, in connection with the actions, statements or omissions that resulted in such Losses as well as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the

14

omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party, the Persons’ relative knowledge and access to information concerning the matter with respect to which the claim was asserted, the opportunity to correct and prevent any statement or omission, and other equitable considerations appropriate under the circumstances. It is hereby agreed that it would not necessarily be equitable if the amount of such contribution were determined by pro rata or per capita allocation. 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 found guilty of such fraudulent misrepresentation. Notwithstanding the foregoing, no Selling Stockholder shall be required to make a contribution in excess of the net proceeds received by such Selling Stockholder from its sale of Registrable Securities in connection with the offering that gave rise to the contribution obligation.

The selling securityholders, including their pledgees, donees, transferees, distributees, beneficiaries or other successors in interest, may from time to time offer some or all of the shares of common stock (collectively, “Securities”) covered by this prospectus. To the extent required, this prospectus may be amended and supplemented from time to time to describe a specific plan of distribution.

The selling securityholders will not pay any of the costs, expenses and fees in connection with the registration and sale of the Securities covered by this prospectus, but they will pay any and all underwriting discounts, selling commissions and stock transfer taxes, if any, attributable to sales of the Securities. We will not receive any proceeds from the sale of the common stock covered hereby.

The selling securityholders may sell the Securities covered by this prospectus from time to time, and may also decide not to sell all or any of the Securities that they are allowed to sell under this prospectus. The selling securityholders will act independently of us in making decisions regarding the timing, manner and size of each sale. These dispositions may be at fixed prices, at market prices prevailing at the time of sale, at prices related to such prevailing market prices, at varying prices determined at the time of sale, or at privately negotiated prices. Sales may be made by the selling securityholders in one or more types of transactions, which may include:

A selling securityholder may also resell all or a portion of its Securities in open market transactions in reliance upon Rule 144 under the Securities Act provided it meets the criteria and conforms to the requirements of Rule 144 and all applicable laws and regulations.

The selling securityholders may enter into sale, forward sale and derivative transactions with third parties, or may sell securities not covered by this prospectus to third parties in privately negotiated transactions. In connection with those sale, forward sale or derivative transactions, the third parties may sell securities covered by this prospectus, including in short sale transactions and by issuing securities that are not covered by this prospectus but are exchangeable for or represent beneficial interests in the common stock. The third parties also may use shares received under those sale, forward sale or derivative arrangements or shares pledged by the selling securityholder or borrowed from the selling securityholders or others to settle such third-party sales or to close out any related open borrowings of common stock. The third parties may deliver this prospectus in connection with any such transactions. Any third party in such sale transactions will be an underwriter and will be identified in a supplement or a post-effective amendment to the registration statement of which this prospectus is a part as may be required.

In addition, the selling securityholders may engage in hedging transactions with broker-dealers in connection with distributions of Securities or otherwise. In those transactions, broker-dealers may engage in short sales of securities in the course of hedging the positions they assume with selling securityholders. The selling securityholders may also sell securities short and redeliver securities to close out such short positions. The selling securityholders may also enter into option or other transactions with broker-dealers which require the delivery of securities to the broker-dealer. The broker-dealer may then resell or otherwise transfer such securities pursuant to this prospectus. The selling securityholders also may loan or pledge shares, and the borrower or pledgee may sell or otherwise transfer the Securities so loaned or pledged pursuant to this prospectus. Such borrower or pledgee also may transfer those Securities to investors in our securities or the selling securityholders’ securities or in connection with the offering of other securities not covered by this prospectus.

To the extent necessary, the specific terms of the offering of Securities, including the specific Securities to be sold, the names of the selling securityholders, the respective purchase prices and public offering prices, the names of any underwriter, broker-dealer or agent, if any, and any applicable compensation in the form of discounts, concessions or commissions paid to underwriters or agents or paid or allowed to dealers will be set forth in a supplement to this prospectus or a post-effective amendment to this registration statement of which this prospectus forms a part. The selling

securityholders may, or may authorize underwriters, dealers and agents to, solicit offers from specified institutions to purchase Securities from the selling securityholders at the public offering price listed in the applicable prospectus supplement. These sales may be made under “delayed delivery contracts” or other purchase contracts that provide for payment and delivery on a specified future date. Any contracts like this will be described in and be subject to the conditions set forth in a supplement to this prospectus or a post-effective amendment to this registration statement of which this prospectus forms a part.

Broker-dealers or agents may receive compensation in the form of commissions, discounts or concessions from the selling securityholders. Broker-dealers or agents may also receive compensation from the purchasers of Securities for whom they act as agents or to whom they sell as principals, or both. Compensation as to a particular broker-dealer might be in excess of customary commissions and will be in amounts to be negotiated in connection with transactions involving securities. In effecting sales, broker-dealers engaged by the selling securityholders may arrange for other broker-dealers to participate in the resales.

In connection with sales of Securities covered hereby, the selling securityholders and any underwriter, broker-dealer or agent and any other participating broker-dealer that executes sales for the selling securityholders may be deemed to be an “underwriter” within the meaning of the Securities Act of 1933, as amended (the “Securities Act”). Accordingly, any profits realized by the selling securityholders and any compensation earned by such underwriter, broker-dealer or agent may be deemed to be underwriting discounts and commissions. Selling securityholders who are “underwriters” under the Securities Act must deliver this prospectus in the manner required by the Securities Act. This prospectus delivery requirement may be satisfied through the facilities of the New York Stock Exchange in accordance with Rule 153 under the Securities Act or satisfied in accordance with Rule 174 under the Securities Act.

We and the selling securityholders have agreed to indemnify each other against certain liabilities, including liabilities under the Securities Act. In addition, we or the selling securityholders may agree to indemnify any underwriters, broker-dealers and agents against or contribute to any payments the underwriters, broker-dealers or agents may be required to make with respect to, civil liabilities, including liabilities under the Securities Act. Underwriters, broker-dealers and agents and their affiliates are permitted to be customers of, engage in transactions with, or perform services for us and our affiliates or the selling securityholders or their affiliates in the ordinary course of business.

In order to comply with applicable securities laws of some states or countries, the Securities may only be sold in those jurisdictions through registered or licensed brokers or dealers and in compliance with applicable laws and regulations. In addition, in certain states or countries the Securities may not be sold unless they have been registered or qualified for sale in the applicable state or country or an exemption from the registration or qualification requirements is available. In addition, any Securities of a selling securityholder covered by this prospectus that qualify for sale pursuant to Rule 144 under the Securities Act may be sold in open market transactions under Rule 144 rather than pursuant to this prospectus.

In connection with an offering of Securities under this prospectus, the underwriters may purchase and sell securities in the open market. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater number of securities than they are required to purchase in an offering. Stabilizing transactions consist of certain bids or purchases made for the purpose of preventing or retarding a decline in the market price of the securities while an offering is in progress.

The underwriters also may impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the underwriters have repurchased securities sold by or for the account of that underwriter in stabilizing or short-covering transactions.

These activities by the underwriters may stabilize, maintain or otherwise affect the market price of the Securities offered under this prospectus. As a result, the price of the Securities may be higher than the price that otherwise might exist in the open market. If these activities are commenced, they may be discontinued by the underwriters at any time. These transactions may be effected on the New York Stock Exchange, the NASDAQ Stock Exchange or another securities exchange or automated quotation system, or in the over-the-counter market or otherwise.
