Such written registration request shall specify the approximate number of Registrable Shares requested to be registered and the anticipated per share price range for such offering, if applicable. The Company shall promptly use its best efforts to effect such registration on an appropriate form under the Securities Act of the Registrable Shares which the Company has been so requested to register; provided, however, that the Company shall not be obligated to effect any registration under the Securities Act except in accordance with the following provisions:

(a) the Company shall not be obligated to file more than (i) three registration statements in total pursuant to this Section 2 plus (ii) one additional registration statement registering all Registrable Shares then owned by SEP I and SEP I’s current or former limited partners that received Registrable Shares in a distribution from SEP I, subject to Section 2.3 (the “Inclusive Registration Statement”);

pursuant to which any “lock-up” restrictions have been imposed on the Company prohibiting such registration (provided, that the Company shall use its best efforts to achieve a shorter period or to have such restrictions released in less than 180 days) or (ii) the Company has determined in good faith that the filing of a registration statement would require the disclosure of material information that the Company has a bona fide business purpose for preserving as confidential, such filing to be delayed until the date which is 90 days after such request for registration pursuant to this Section 2; provided, that the Company may only so delay the filing or effectiveness of a registration statement pursuant to this Section 2.1(b)(ii) on one occasion during any twelve month period; and

(c) with respect to the registration pursuant to this Section 2, the Company may include in such registration any Primary Shares or Other Shares; provided, however, that if the managing underwriter advises the Company in writing that the inclusion of all Registrable Shares, Primary Shares and Other Shares proposed to be included in such registration would adversely affect the successful marketing (including pricing) of all such securities, then the number of Registrable Shares, Primary Shares and Other Shares proposed to be included in such registration shall be included in the following order:

(i) First, the Registrable Shares held by all Selling Investors, pro rata based upon the number of Registrable Shares owned by each such Selling Investor at the time of such registration;

(ii) Second, the Primary Shares; and

(iii) Third, the Other Shares.

2.2 The Holder or Holders requesting a registration pursuant to this Section may, in the notice delivered pursuant to Section 2.1 or in connection with any “shelf take-down” under such registration statement, elect that such registration or offering, as the case may be, cover an underwritten offering. Upon such election, such Holder shall elect one or more nationally recognized firms of investment banks to act as the managing underwriters and shall select any additional investment banks to be used in connection with such offering, provided that such investment banks must be reasonably satisfactory to the Company. The Company shall, together with Selling Investors, enter into a customary underwriting agreement with such underwriters.

2.3 A requested registration under this Section 2 may be rescinded by written notice to the Company by the Selling Investors holding a majority of the Registrable Shares to be included in such registration under the following circumstances:

(i) If such registration statement is rescinded prior to the filing date, such rescinded registration shall not count as a registration statement initiated pursuant to this Section 2 for purposes of Section 2.1;

(ii) If such registration statement is rescinded after the filing date but prior to its effective date, such rescinded registration shall not

4

count as a registration statement initiated pursuant to this Section 2 for purposes of Section 2.1 if the Selling Investors (x) have reimbursed the Company for all out-of-pocket expenses incurred by the Company in connection with such rescinded registration or (y) (1) reasonably believed that the registration statement contained an untrue statement of material fact or omitted to state a material fact required to be stated therein or necessary to make the statements made therein not misleading, (2) notified the Company of such fact and requested that the Company correct such alleged misstatement or omission and (3) the Company has refused to correct such alleged misstatement or omission; and

(iii) A registration shall not count as a registration statement initiated pursuant to this Section 2 for purposes of Section 2.1 unless it becomes effective and either (1) the Selling Investors are able to sell at least 80% of the Registrable Shares sought to be included in such registration statement or (2) such registration statement is kept effective for at least 180 days prior to such rescission notice.

3. Piggyback Registration. If at any time the Company proposes for any reason to register Primary Shares or Other Shares under the Securities Act (other than on Form S-4 or Form S-8 promulgated under the Securities Act or any successor forms thereto) including, without limitation, any registration pursuant to the exercise of the demand registration rights of any Person other than a Holder, on any form that would also permit the registration of Registrable Shares, or (to the extent inclusion of Registrable Shares is permitted by applicable laws, rules and regulations) to offer Primary Shares or Other Shares pursuant to a “shelf take-down,” the Company shall promptly give written notice to each Holder of its intention to so register or offer the Primary Shares or Other Shares and, upon the written request, given within 15 days after delivery of any such notice by the Company, of any Holder to include in such registration Registrable Shares held by such Holder (which request shall specify the number of Registrable Shares proposed to be included in such registration or offering), the Company shall use its best efforts to cause all such Registrable Shares to be included in such registration or offering on the same terms and conditions as the securities otherwise being sold in such registration or offering; provided, however, that if at any time after giving written notice of its intention to register or offer any securities, and prior to the effective date of the registration statement or filing of the preliminary prospectus supplement filed in connection with such registration or offering, as the case may be, the Company shall determine for any reason not to proceed with the proposed registration or offering of the securities to be sold by it, the Company may, at its election, give written notice of such determination to each Holder of Registrable Shares and, thereupon, shall be relieved of its obligation to register or offer any Registrable Shares in connection with such registration or offering; provided further, however, that if the managing underwriter advises the Company that the inclusion of all Registrable Shares or Other Shares proposed to be included in such registration or offering would interfere with the successful marketing (including pricing) of the Primary Shares or Other Shares proposed to be registered or offered by the Company, then the number of Primary Shares, Registrable Shares and Other Shares proposed to be included in such registration or offering shall be included in the following order:

5

3.1 First, the Primary Shares or Other Shares, as applicable; and

3.2 Second, the Registrable Shares held by all Selling Investors, pro rata based upon the number of Registrable Shares owned by each such Selling Investor at the time of such registration or offering, as the case may be.

In connection with any underwritten offering under this Section 3, the Company shall not be required to include Registrable Shares in such underwritten offering unless the Holders of such Registrable Shares accept the terms of the underwriting of such offering that have been agreed upon between the Company and the underwriters selected by the Company, including without limitation, the underwriting agreement and the fees and expenses in connection therewith.

4. S-3 Registrations. If (i) at any time following June 10, 2012 SEP I or Holders who beneficially own at least 4,300,000 Registrable Shares request that the Company file a registration statement on Form S-3 or any successor thereto for a public offering of all or any portion of the Registrable Shares held by such Holder, and (ii) the Company is entitled to use Form S-3 or any successor thereto to register such shares, then the Company shall use its best efforts to register under the Securities Act on Form S-3 or any successor thereto, for public sale in accordance with the method of disposition specified in such notice, the number of shares of Registrable Shares specified in such notice. Whenever the Company is required by this Section 4 to use its best efforts to effect the registration of Registrable Shares, each of the procedures and requirements of Section 2 (including but not limited to the requirement that the Company notify all holders of Registrable Shares from whom notice has not been received and provide them with the opportunity to participate in the offering) shall apply to such registration or offering in connection therewith. Notwithstanding anything to the contrary contained herein, no request may be made under this Section 4 within six months after the effective date of a registration statement filed by the Company or the occurrence of a “shelf take-down” under a then-effective registration statement covering a firm commitment underwritten public offering in which the holders of Registrable Shares shall have been entitled to join pursuant to Section 2 or 3 in which there shall have been effectively registered or sold, as the case may be, all Registrable Shares as to which registration shall have been requested pursuant to which any “lock-up” restrictions have been imposed on the Company prohibiting such registration (provided, that the Company shall use its best efforts to achieve a shorter period or have such restrictions released in less than six months). There is no limitation on the number of registrations pursuant to this Section 4 that the Company is obligated to effect.

5. Expenses. The Company shall bear the expense of any registrations effected pursuant to Sections 2, 3 and 4 of this Agreement including, without limitation, all registration and filing fees, fees and expenses of complying with securities and blue sky laws, printing expenses, and fees and expenses of the Company’s counsel and accountants, including without limitation expenses of any audits incident to or required by any such registrations, and the reasonable fees and expenses of the Selling Investors’ Counsel, but excluding any underwriters’ or brokers’ discounts or commissions, transfer taxes (to the extent that such taxes are required by law to be paid by the Selling Investors) and the fees of any counsel to any Selling Investor, other than the Selling Investors’ Counsel (it being understood that the fees and expenses of any underwriter and such underwriter’s counsel shall be the responsibility of such underwriter and the Selling Investors).

6

6. Preparation and Filing. If and whenever the Company is under an obligation pursuant to the provisions of this Agreement to use its best efforts to effect the registration of any Registrable Shares under the Securities Act, the Company shall, as expeditiously as practicable:

6.1 with respect to a registration under Sections 2, 3 and 4 of this Agreement, use its best efforts to cause a registration statement that registers such Registrable Shares to become and remain effective for a period of 180 days or until all of such Registrable Shares have been disposed of (if earlier); provided, however, that the Company may discontinue any registration of its securities that is being effected pursuant to Section 3 hereof at any time prior to the effective date of the registration statement relating thereto; provided further, that if the Inclusive Registration Statement is a “shelf” registration statement pursuant to Rule 415 under the Securities Act or successor rule, then the Company shall be required to use its best efforts to cause such registration statement to remain effective for a period of two years, exclusive of any periods when such registration statement is not so effective;

6.2 furnish, at least ten business days before filing a registration statement that registers such Registrable Shares, a prospectus relating thereto or any amendments or supplements relating to such a registration statement or prospectus, to each holder of Registrable Shares, to any Selling Investors and to the Selling Investors’ Counsel, copies of all such documents proposed to be filed with the SEC (it being understood that such ten-business-day period need not apply to successive drafts of the same document proposed to be filed so long as such successive drafts are supplied to such counsel in advance of the proposed filing by a period of time that is customary and reasonable under the circumstances);

6.3 prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection therewith as may be necessary to keep such registration statement effective for at least the periods set forth in this Agreement or until all of such Registrable Shares have been disposed of (if earlier) and to comply with the provisions of the Securities Act with respect to the registration of the sale or other disposition of such Registrable Shares;

6.4 notify in writing the Selling Investors promptly (i) of the receipt by the Company of any notification with respect to any comments by the SEC with respect to such registration statement or prospectus or any amendment or supplement thereto or any request by the SEC for the amending or supplementing thereof or for additional information with respect thereto, (ii) of the receipt by the Company of any notification with respect to the issuance by the SEC of any stop order suspending the effectiveness of such registration statement or prospectus or any amendment or supplement thereto or the initiation or threatening of any proceeding for that purpose and (iii) of the receipt by the Company of any notification with respect to the suspension of the qualification of such Registrable Shares for sale in any jurisdiction or the initiation or threatening of any proceeding for such purposes;

6.5 use its best efforts to register or qualify such Registrable Shares covered by such registration statement under such other securities or blue sky laws of such jurisdictions

7

as any Selling Investor reasonably requests and do any and all other acts and things which may be reasonably necessary or advisable to enable such Selling Investor to consummate the disposition in such jurisdictions of the Registrable Shares owned by such Selling Investor; provided, however, that the Company will not be required to qualify generally to do business, subject itself to general taxation or consent to general service of process in any jurisdiction where it would not otherwise be required so to do but for this Section 6.5;

6.6 furnish to each Selling Investor on a timely basis, such number of copies of a summary prospectus or other prospectus, including a preliminary prospectus, in conformity with the requirements of the Securities Act, and such other documents as such Selling Investor may reasonably request in order to facilitate the public sale or other disposition of such Registrable Shares; provided, however, that the Company shall have no such obligation to furnish copies of a final prospectus if the conditions of Rule 172(c) under the Securities Act are satisfied by the Company; provided further, that if a final prospectus is not timely filed by the Company with the SEC in accordance with Rule 172(c) (without regard to any cure period provided by such rule) then, upon the written request of the Selling Investor, the Company shall furnish such number of copies of a final prospectus as such Selling Investor shall reasonably request;

6.7 use its best efforts to cause such Registrable Shares to be registered with or approved by such other governmental agencies or authorities as may be necessary by virtue of the business and operations of the Company to enable the seller or sellers thereof to consummate the disposition of such Registrable Shares;

6.8 notify on a timely basis each Selling Investor at any time when a prospectus relating to such Registrable Shares is required to be delivered under the Securities Act within the appropriate period mentioned in Section 6.1, of the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, included an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing and, at the request of such seller, prepare and furnish to such seller a reasonable number of copies of a supplement to or an amendment of such prospectus as may be necessary so that, as thereafter delivered to the offerees of such shares, such prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing;

6.9 make available for inspection by any counsel to any Selling Investor and the Selling Investors’ Counsel or any underwriter participating in any disposition pursuant to such registration statement and any attorney, accountant or other agent retained by any such underwriter (collectively, the “Inspectors”), all pertinent financial and other records, pertinent corporate documents and properties of the Company (collectively, the “Records”), as shall be reasonably necessary to enable them to exercise their due diligence responsibility, and cause the Company’s officers, directors and employees to supply all information (together with the Records, the “Information”) reasonably requested by any such Inspector in connection with such registration statement. Any of the Information which the Company determines in good faith to be confidential, and of which determination the Inspectors are so notified, shall not be disclosed

8

by the Inspectors unless (i) the disclosure of such Information is necessary to avoid or correct a misstatement or omission of a material fact in the registration statement, (ii) the release of such Information is ordered pursuant to a subpoena or other order from a court of competent jurisdiction or (iii) such Information has otherwise been made generally available to the public. The Selling Investor agrees that it will, upon learning that disclosure of such Information is sought in a court of competent jurisdiction, give notice to the Company and allow the Company, at the Company’s expense, to undertake appropriate action to prevent disclosure of the Information deemed confidential;

6.10 use its best efforts to obtain from its independent certified public accountants and reserve engineers “comfort” letters in customary form and at customary times and covering matters of the type customarily covered by comfort letters;

6.12 provide a transfer agent and registrar (which may be the same entity and which may not be the Company) for such Registrable Shares;

6.13 issue to any underwriter to which any Selling Investor may sell shares in such offering certificates evidencing such Registrable Shares; provided, however, that the Company shall have the right to approve any such underwriter in connection with an underwritten offering pursuant to Section 2 hereof, with such approval not to be unreasonably withheld, and the Company shall have the right to select such underwriter in connection with an underwritten offering pursuant to Section 3 hereof;

6.14 list such Registrable Shares on any national securities exchange on which any shares of the Common Stock are listed, or if the Common Stock is not then listed on a national securities exchange, use its best efforts to qualify such Registrable Shares for inclusion on such national securities exchange as the holders of a majority of such Registrable Shares shall request;

6.15 otherwise use its best efforts to comply with all applicable rules and regulations of the SEC and, if required under such rules and regulations, make available to its security holders, as soon as reasonably practicable, earnings statements (which need not be audited) covering a period of 12 months beginning within three months after the effective date of the registration statement, which earnings statements shall satisfy the provisions of Section 11(a) of the Securities Act;

6.16 use its best efforts to take all other steps necessary to effect the registration of such Registrable Shares contemplated hereby; and

6.17 use its best efforts to make available its senior executive and financial officers to participate at the reasonable request of any underwriter in marketing presentations to potential investors.

7. Indemnification.

9

7.1 In connection with any registration of any Registrable Shares under the Securities Act pursuant to this Agreement, the Company shall indemnify and hold harmless each Selling Investor, its officers and directors, each underwriter, broker or any other person acting on behalf of such Selling Investor and each other person, if any, who controls any of the foregoing persons within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act against any losses, claims, damages or liabilities, joint or several (or actions in respect thereof), to which any of the foregoing persons may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon an untrue statement or alleged untrue statement of a material fact contained in the registration statement under which such Registrable Shares were registered under the Securities Act, any preliminary prospectus or final prospectus contained therein or otherwise filed with the SEC, any amendment or supplement thereto or any document incident to registration or qualification of any Registrable Shares, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and shall reimburse such Selling Investor, such officer or director, such underwriter, such broker or such other person acting on behalf of such Selling Investor and each such controlling person for any legal or other expenses reasonably incurred by any of them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of or is based upon (i) an untrue statement or alleged untrue statement or omission or alleged omission made in said registration statement, preliminary prospectus, final prospectus, amendment, supplement or document incident to registration or qualification of any Registrable Shares in reliance upon and in conformity with written information furnished to the Company through an instrument duly executed by Selling Investor or underwriter specifically for use in the preparation thereof or (ii) offers or sales by such Selling Investor “by means of” (as defined in Securities Act Rule 159A) a “free writing prospectus” (as defined in Securities Act Rule 405) that was not authorized in writing by the Company; provided, further, that with respect to any prospectus, the foregoing indemnity shall not inure to the benefit of (a) any underwriter or, in the case of a registration statement filed with respect to an offering which is not an underwritten offering, any Selling Investor, from whom the person asserting any losses, claims, damages and liabilities and judgments purchased Registrable Shares or (b) any person controlling such underwriter or Selling Investor, if (i) a copy of the prospectus (as then amended or supplemented if the Company shall have furnished any amendments or supplements thereto) was required by law to have been delivered by such underwriter or Selling Investor (as applicable), (ii) the prospectus had not been sent or given by or on behalf of such underwriter or Selling Investor (as applicable), (iii) the prospectus had not been sent or given by or on behalf of such underwriter or Selling Investor (as applicable) to such person with or prior to entry into the contract of sale of the Registrable Shares with such person, (iv) the prospectus (as so amended and supplemented) would have cured the defect giving rise to such loss, claim, damage, liability or judgment and (v) such failure to deliver the prospectus (as so amended and supplemented) was not the result of noncompliance by the Company with Section 6.6 hereof.

7.2 In connection with any registration of Registrable Shares under the Securities Act pursuant to this Agreement, each Selling Investor shall indemnify and hold harmless (in the same manner and to the same extent as set forth in the preceding paragraph of this Section) the Company, each director of the Company, each officer of the Company who

10

shall sign such registration statement, each underwriter, broker or other person acting on behalf of the Company, each person who controls any of the foregoing persons within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and each other Selling Investor under such registration statement (i) with respect to any statement or omission from such registration statement, any preliminary prospectus or final prospectus contained therein or otherwise filed with the SEC, any amendment or supplement thereto or any document incident to registration or qualification of any Registrable Shares, if such statement or omission was made in reliance upon and in conformity with written information furnished to the Company or such underwriter through an instrument duly executed by Selling Investor specifically for use in connection with the preparation of such registration statement, preliminary prospectus, final prospectus, amendment, supplement or document, (ii) arises out of or is based upon offers or sales by such Selling Investor “by means of” (as defined in Securities Act Rule 159A) a “free writing prospectus” (as defined in Securities Act Rule 405) that was not authorized in writing by the Company and (iii) in the event that a copy of the prospectus (as then amended or supplemented if the Company shall have furnished any amendments or supplements thereto) was required by law to have been delivered by such Selling Investor and (A) the prospectus had not been sent or given by or on behalf of such Selling Investor, (B) the prospectus had not been sent or given by or on behalf of such Selling Investor to such person with or prior to entry into the contract of sale of the Registrable Shares with such person, (C) the prospectus (as so amended and supplemented) would have cured the defect giving rise to a loss, claim, damage, liability or judgment and (D) such failure to deliver the prospectus (as so amended and supplemented) was not the result of noncompliance by the Company with Section 6.6 hereof; provided, however, that the obligation to indemnify will be several, not joint and several, among such Selling Investors, and the maximum amount of liability in respect of such indemnification shall be in proportion to and limited to, in the case of each Selling Investor, an amount equal to the net proceeds (after underwriting fees, commissions or discounts) actually received by such Selling Investor from the sale of Registrable Shares effected pursuant to such registration.

7.3 The indemnification required by this Section 7 will be made by periodic payments during the course of the investigation or defense, as and when bills are received or expenses incurred, subject to prompt refund in the event any such payments are determined not to have been due and owing hereunder.

7.4 Promptly after receipt by an indemnified party of notice of the commencement of any action involving a claim referred to in the preceding paragraphs of this Section 7, such indemnified party will, if a claim in respect thereof is made against an indemnifying party, give written notice to the latter of the commencement of such action (it being understood that no delay in delivering or failure to deliver such notice shall relieve the indemnifying persons from any liability or obligation hereunder unless (and then solely to the extent that) the indemnifying person is prejudiced by such delay and/or failure). In case any such action is brought against an indemnified party, the indemnifying party will be entitled to participate in and to assume the defense thereof, jointly with any other indemnifying party similarly notified to the extent that it may wish, 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, the indemnifying party shall not be responsible for any legal or other expenses subsequently incurred by the latter in connection with the defense thereof; provided, however, that if any indemnified party shall have reasonably concluded that

11

there may be one or more legal or equitable defenses available to such indemnified party which are additional to or conflict with those available to the indemnifying party, or that such claim or litigation involves or could have an effect upon matters beyond the scope of the indemnity agreement provided in this Section 7, the indemnifying party shall not have the right to assume the defense of such action on behalf of such indemnified party and such indemnifying party shall reimburse such indemnified party and any person controlling such indemnified party for that portion of the fees and expenses of any counsel retained by the indemnified party which is reasonably related to the matters covered by the indemnification provided in this Section 7.

7.5 The indemnification provided for under this Agreement will remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling person of such indemnified party and will survive the transfer of securities.

7.6 If the indemnification provided for in this Section 7 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any loss, claim, damage, liability or action referred to herein, then the indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall contribute to the amounts paid or payable by such indemnified party as a result of such loss, claim, damage, liability or action in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with the statements or omissions which resulted in such loss, claim, damage or liability 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 omission or alleged omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Selling Investors agree that it would not be just and equitable if contributions pursuant to this paragraph were determined by pro rata allocation or by any other method of allocation which did not take into account the equitable considerations referred to herein.

9. Agreements of the Selling Investors.

12

9.1 The Selling Investors shall furnish to the Company such written information regarding such Selling Investors and the distribution proposed by such Selling Investors as the Company may reasonably request in writing and as shall be reasonably required in connection with any registration, qualification or compliance referred to in this Agreement.

9.2 No Selling Investor shall, nor shall any Selling Investor permit any officer, director, underwriter, broker or any other person acting on behalf of such Selling Investor to, use any free writing prospectus (as defined in Rule 405 under the Securities Act) in connection with any registration statement covering Registrable Shares, without the prior written consent of the Company.

10. Exchange Act Compliance. The Company covenants that it shall (i) file the reports required to be filed by it (if so required) under the Securities Act and the Exchange Act in a timely manner and, if at any time the Company is not required to file such reports, it will, upon the written request of any Holder of Registrable Shares, make publicly available other information necessary to permit sales pursuant to Rule 144 under the Securities Act and (ii) take such further action as any Holder may reasonably request in writing, all to the extent required from time to time to enable such Holder to sell Registrable Shares without registration under the Securities Act pursuant to the exemptions provided by Rule 144 thereunder. Upon the request of any Holder, the Company shall deliver to such Holder a written statement as to whether it has complied with such information and requirements.

11. No Conflicting Registration Rights. The Company represents and warrants to SEP I that there are no registration rights with respect to any equity interest in the Company other than the registration rights granted hereby. The Company shall not (i) grant any registration rights to third parties which are more favorable than or inconsistent with the rights granted hereunder, or (ii) enter into any agreement, take any action, or permit any change to occur, with respect to its securities that violates or subordinates the rights expressly granted to the holders of Registrable Securities in this Agreement.

12. Enforcement.

12.1 Remedies at Law or in Equity. Each Holder, on the one hand, and the Company, on the other hand, may proceed to protect and enforce its rights by suit in equity or action at law, whether for the specific performance of any term contained in this Agreement or for an injunction against the breach of any such term or in aid of the exercise of any term contained in this Agreement, or to enforce any other legal or equitable right of such Holder, on the one hand, or the Company on the other hand, or to take any one or more of such actions.

In the event a Holder brings such an action against the Company or the Company brings an action against a Holder arising under this Agreement, the prevailing party in such dispute shall be entitled to recover from the losing party all fees, costs and expenses of enforcing any right of such prevailing party under or with respect to this Agreement, including without limitation such reasonable fees and expenses of attorneys and accountants, which shall include, without limitation, all fees, costs and expenses of appeals.

13

12.2 Cumulative Remedies. None of the rights, powers or remedies conferred upon a Holder, on the one hand, or the Company, on the other hand, shall be mutually exclusive, and each such right, power or remedy shall be cumulative and in addition to every other right, power or remedy, now or hereafter available at law, in equity, by statute or otherwise.

12.3 No Implied Waiver. Except as expressly provided in this Agreement, no course of dealing between the Company and a Holder and no delay in exercising any such right, power or remedy conferred hereby now or hereafter existing at law in equity, by statute or otherwise, shall operate as a waiver of, or otherwise prejudice, any such right, power or remedy.

13. Miscellaneous.

(b) Upon the effectuation of each such waiver, the Company shall promptly give written notice thereof to each Holder who have not previously consented thereto in writing.
