2.1    Shelf Registration.

(a)    On or prior to the 120th day following the Closing, the Company will prepare and file a Shelf Registration Statement (which Shelf Registration Statement shall be an Automatic Shelf Registration Statement if the Company is then eligible to file an Automatic Shelf Registration Statement) registering for resale the Registrable Securities under the Securities Act; provided, however, that the Company shall not, and shall not be required, to file such Shelf Registration Statement prior to October 14, 2015. The plan of distribution indicated in the Shelf Registration Statement will include all such methods of sale as any Holder may reasonably request in writing prior to the filing of the Shelf Registration Statement and that can be included in the Shelf Registration Statement under the rules and regulations of the SEC. The Company shall use its commercially reasonable efforts to cause the Shelf Registration Statement to be declared effective by the SEC as promptly as practicable following such filing. Until such time as all Registrable Securities cease to be Registrable Securities or the Company is no longer eligible to maintain a Shelf Registration Statement, the Company shall use its commercially reasonable efforts to keep current and effective such Shelf Registration Statement and file such supplements or amendments to such Shelf Registration Statement (or file a new Shelf Registration Statement (which Shelf Registration Statement shall be an Automatic Shelf Registration Statement if the Company is then eligible to file an Automatic Shelf Registration Statement) when such preceding Shelf Registration Statement expires pursuant to the rules of the SEC) as may be necessary or appropriate in order to keep such Shelf Registration Statement continuously effective and useable for the resale of all Registrable Securities under the Securities Act. Any Shelf Registration Statement when declared effective (including the documents incorporated therein by reference) will comply in all material respects as to form with all applicable requirements of the Securities Act and the Exchange Act and will not contain 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.

(b)    Any one or more Holders of Registrable Securities may request to sell all or any portion of their Registrable Securities in an underwritten offering that is registered pursuant to the Shelf Registration Statement (each, an “Underwritten Shelf Takedown”); provided, however, that in the case of each such Underwritten Shelf Takedown, such Holder or Holders will be entitled to make such demand only if the proceeds from the sale of Registrable Securities in the offering (before the deduction of underwriting discounts) is reasonably expected to exceed, in the aggregate, $175 million; provided, further that the Company shall not be obligated to effect more than three Underwritten Shelf Takedowns during any period of twelve consecutive months and shall not be obligated to effect an Underwritten Shelf Takedown within ninety days after the pricing of a previous Underwritten Shelf Takedown. The Company shall not be deemed to have effected any Underwritten Shelf Takedown if the Holders participating in such offering are not able to sell at least 50% of the Registrable Securities desired to be sold in such Underwritten Shelf Takedown.

(c)    All requests (a “Demand Request”) for Underwritten Shelf Takedowns shall be made by the Holder or Holders making such request (the “Requesting Holder”) by giving written notice to the Company. Each Demand Request shall specify the approximate number of

Registrable Securities to be sold in the Underwritten Shelf Takedown and the expected price range (net of underwriting discounts and commissions) of such Underwritten Shelf Takedown. Within three Business Days after receipt of any Demand Request, the Company shall send written notice of such requested Underwritten Shelf Takedown to all other Holders of Registrable Securities (the “Company Notice”) and shall include in such Underwritten Shelf Takedown all Registrable Securities with respect to which the Company has received written requests for inclusion therein within five Business Days after sending the Company Notice.

(d)    The Company shall select one or more nationally prominent firms of investment bankers reasonably acceptable to the Participating Majority to act as the lead managing underwriter or underwriters in connection with such Underwritten Shelf Takedown. All Holders proposing to distribute their securities through such underwriting shall enter into an underwriting agreement with such underwriter or underwriters in accordance with Section 2.1(g). The Company shall not, without the written consent of the Participating Majority, include in such Underwritten Shelf Takedown any securities other than those beneficially owned by the participating Holders. The “Participating Majority” shall mean, with respect to any particular

Underwritten Shelf Takedown, the Holder(s) of a majority of the Registrable Securities requested to be included in such Underwritten Shelf Takedown; provided, however, that in the event that, with respect to any particular Underwritten Shelf Takedown, either FR Rhino Holdings, LLC (“First Reserve”) or ZAM Ventures, LP and its affiliates (“Ziff”) proposes to sell in such offering 20% or more of the Registrable Securities acquired by it at the Closing, then it shall constitute the “Participating Majority” for purposes of such Underwritten Shelf Takedown; provided, further, however, that if each of First Reserve and Ziff proposes to sell in such offering 20% or more of the Registrable Securities acquired by it at the Closing, then they shall jointly constitute the Participating Majority, provided, that if they shall fail to agree on any matter in such capacity, the one of them that proposes to sell the largest number of Registrable Securities in such offering shall be the “Participating Majority” for purposes of such Underwritten Shelf Takedown.

(e)    If the managing underwriters for such Underwritten Shelf Takedown advise the Company and the participating Holders in writing that, in their opinion, marketing factors require a limitation of the amount of securities to be underwritten (including Registrable Securities) because the amount of securities to be underwritten is likely to have an adverse effect on the price, timing or the distribution of the securities to be offered, then the Company shall so advise all Holders of Registrable Securities which would otherwise be underwritten pursuant hereto, and the amount of Registrable Securities that may be included in the underwriting shall be allocated among participating Holders, (i) first among the participating Holders as nearly as possible on a pro rata basis based on the total amount of Registrable Securities held by such Holders requested to be included in such underwriting and (ii) second to the extent all Registrable Securities requested to be included in such underwriting by the participating Holders have been included, to any securities to be included with the written consent of the Participating Majority pursuant to the previous sentence allocated on such basis as the Company shall determine. The Company shall prepare preliminary and final prospectus supplements for use in connection with the Underwritten Shelf Takedown, containing such additional information as may be reasonably requested by the underwriter(s).

(f)    Upon written notice to the Holders of Registrable Securities, the Company shall be entitled to suspend, for a period of time (each, a “Suspension Period”), the use of any

Registration Statement or Prospectus and shall not be required to amend or supplement the Registration Statement, any related Prospectus or any document incorporated therein by reference if the board of directors, chief executive officer or chief financial officer of the Company determines in its or his or her reasonable good faith judgment that the Registration Statement or any Prospectus may contain an untrue statement of a material fact or may omit any fact necessary to make the statements in the Registration Statement or Prospectus not misleading; provided, that the Company shall use its good faith efforts to amend the Registration Statement or Prospectus to correct such untrue statement or omission as promptly as reasonably practicable, unless the Company determines in good faith that such amendment would reasonably be expected to have a materially detrimental effect on the Company. The Holders acknowledge and agree that written notice of any Suspension Period may constitute material non-public information regarding the Company and shall keep the existence and contents of any such written notice confidential.

(g)    If requested by the underwriters for an Underwritten Shelf Takedown, the Company shall enter into an underwriting agreement with such underwriters for such offering, such agreement to be form and substance (including with respect to representations and warranties by the Company) as is customarily given by the Company to underwriters in an underwritten public offering, and to contain indemnities to the effect and to the extent provided in Section 2.7. The Holders of Registrable Securities participating in the Underwritten Shelf Takedown shall be parties to such underwriting agreement; provided, however, that no such Holder shall be required to (i) make any representations or warranties in connection with any such registration other than representations and warranties as to (A) such Holder’s ownership of his or its Registrable Securities to be sold or transferred free and clear of all liens, claims and encumbrances, (B) such Holder’s power and authority to effect such transfer and (C) such matters pertaining to compliance with securities laws as may be reasonably requested or (ii) undertake any indemnification obligations to the Company or the underwriters with respect thereto except as otherwise provided in Section 2.7. No Holder may participate in the Underwritten Shelf Takedown unless such Holder agrees to sell its Registrable Securities on the basis provided in such underwriting agreement and completes and executes all questionnaires, powers of attorney, indemnities and other documents reasonably required under the terms of such underwriting agreement. Each participating Holder may, at its option, require that any or all of the representations and warranties by, and the other agreements on the part of, the Company to and for the benefit of such underwriters also be made to and for such participating Holder’s benefit and that any or all of the conditions precedent to the obligations of such underwriters under such underwriting agreement also be conditions precedent to its obligations.

(a)    Each time the Company proposes to register any of its equity securities (other than pursuant to an Excluded Registration) under the Securities Act for sale to the public (whether for the account of the Company or the account of any securityholder of the Company) and the form of registration statement to be used permits the registration of Registrable Securities, the Company shall give prompt written notice to each Holder of Registrable Securities (which notice shall be given not less than 10 days prior to the anticipated filing date), which notice shall offer each such Holder the opportunity to include any or all of its or his Registrable Securities in such registration statement, subject to the limitations contained in Section 2.2(b) hereof. Each Holder who desires to have its or his Registrable Securities included in such registration

statement shall so advise the Company in writing (stating the number of shares desired to be registered) within five days after the date of such notice from the Company. Any Holder shall have the right to withdraw such Holder’s request for inclusion of such Holder’s Registrable Securities in any registration statement pursuant to this Section 2.2(a) by giving written notice to the Company of such withdrawal. Subject to Section 2.2(b) below, the Company shall include in such registration statement all such Registrable Securities so requested to be included therein; provided, however, that the Company may at any time withdraw or cease proceeding with any such registration if it shall at the same time withdraw or cease proceeding with the registration of all other equity securities originally proposed to be registered. For the avoidance of doubt, any registration or offering pursuant to this Section 2.2 shall not be considered an Underwritten Shelf Takedown for purposes of Section 2.1 of this Agreement.

(b)    With respect to any registration pursuant to Section 2.2(a), if the managing underwriter advises the Company that the inclusion of Registrable Securities requested to be included in the Registration Statement will materially and adversely affect the price or success of the offering (a “Material Adverse Effect”), the Company will be obligated to include in the Registration Statement (after all such shares for its own account), as to each Requesting Holder, only a portion of the shares such Holder has requested be registered equal to the product of: (i) the ratio which such Holder’s requested shares bears to the total number of shares requested to be included in such Registration Statement by all Persons (including Holders) who have requested (pursuant to this Agreement or other contractual registration rights) that their shares be included in such Registration Statement; and (ii) the maximum number of Registrable Securities that the managing underwriter advises may be sold in an offering covered by the Registration Statement without a Material Adverse Effect. If, as a result of the provisions of this Section 2.2(b), any Holder shall not be entitled to include all Registrable Securities in a registration that such Holder has requested to be so included, such Holder may withdraw such Holder’s request to include Registrable Securities in such Registration Statement. No Person may participate in any Registration Statement pursuant to Section 2.2(a) unless such Person (i) agrees to sell such person’s Registrable Securities on the basis provided in any underwriting arrangements approved by the Company and (ii) completes and executes all questionnaires, powers of attorney, indemnities, underwriting agreements and other documents, each in customary form, reasonably required under the terms of such underwriting arrangements; provided, however, that no such Person shall be required to (A) make any representations or warranties in connection with any such registration other than representations and warranties as to (1) such Person’s ownership of his or its Registrable Securities to be sold or transferred free and clear of all liens, claims and encumbrances, (2) such Person’s power and authority to effect such transfer and (3) such matters pertaining to compliance with securities laws as may be reasonably requested or (B) undertake any indemnification obligations to the Company or the underwriters with respect thereto except as otherwise provided in Section 2.7.

2.3    Holdback Agreement. In connection with any Underwritten Shelf Takedown or other registered underwritten offering of equity securities by the Company (a “Company Underwritten Offering”) commencing after the date of execution of the Merger Agreement (other than any registration on Form S-8, S-4 or any successor forms thereto), each Holder agrees, with respect to the Registrable Securities owned by such Holder, to be bound by any and all restrictions on the sale, disposition, distribution, hedging or other transfer of any interest in Registrable Securities (except with respect to such Registrable Securities as are proposed to be

offered pursuant to the Underwritten Shelf Takedown or other registered underwritten offering), or any securities convertible into or exchangeable or exercisable for such securities, as are imposed on the Company, without prior written consent from the managing underwriter of such Company Underwritten Offering, for the period commencing on and ending 90 days following the date of pricing of such Company Underwritten Offering (subject to extension in connection with any earnings release or other release of material information pursuant to FINRA Rule 2711(f) to the extent applicable) (the “Lock-Up Period”). If requested by the managing underwriter, each Holder agrees to execute a lock-up agreement in favor of the Company’s underwriters to such effect that the Company’s underwriters in any relevant Company Underwritten Offering shall be third party beneficiaries of this Section 2.3. The provisions of this Section 2.3 will no longer apply to a Holder once such Holder ceases to hold at least 1% of the Registrable Securities acquired as a result of the transactions contemplated in the Merger Agreement. Notwithstanding anything to the contrary set forth in this Section 2.3, (i) each Holder may sell or transfer any Registrable Securities to any Affiliate of such Holder, so long as such Affiliate agrees to be and remains bound hereby, (ii) each Holder may enter into a bona fide pledge of any Registrable Securities (and any foreclosure on any such pledge shall also be permitted), and (iii) any hedging transaction with respect to an index or basket of securities where the equity securities of the Company constitute a de minimis amount shall not be prohibited pursuant to this Section 2.3.

2.4    Registration Procedures.

In addition, for the avoidance of doubt, the Company shall pay its internal expenses in connection with the performance of or compliance with this Agreement (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), the expense of any annual audit or quarterly review, the expense of any liability insurance and the expenses and fees for listing the securities to be registered on each securities exchange on which they are to be listed. All Selling Expenses relating to Registrable Securities registered shall be borne by the Holders of such Registrable Securities pro rata on the basis of the number of Registrable Securities sold.

(a)    The Company agrees to indemnify and reimburse, to the fullest extent permitted by law, each Holder that is a seller of Registrable Securities, and each of its employees, advisors, agents, representatives, partners, officers, and directors and each Person who controls such Holder (within the meaning of the Securities Act or the Exchange Act) and any agent or investment advisor thereof (collectively, the “Seller Affiliates”) (i) against any and all losses, claims, damages, liabilities and expenses, joint or several (including, without limitation, attorneys’ fees and disbursements except as limited by Section 2.7(c)) based upon, arising out of, related to or resulting from any untrue or alleged untrue statement of a material fact contained in any Registration Statement or Prospectus or any amendment thereof or supplement thereto, or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) against any and all losses, liabilities, claims, damages and expenses whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation or investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever based upon, arising out of, related to or resulting from any such untrue statement or omission or alleged untrue statement or omission, and (iii) against any and all costs and expenses (including reasonable fees and disbursements of counsel) as may be reasonably incurred in investigating, preparing or defending against any litigation, investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon, arising out of, related to or resulting from any such untrue statement or omission or alleged untrue statement or omission, or such violation of the Securities Act or Exchange Act, to the extent that any such expense or cost is not paid under subparagraph (i) or (ii) above; except insofar as any such statements are made in reliance upon information furnished to the Company in writing by such seller or any Seller Affiliate expressly for use therein. The reimbursements required by this Section 2.7(a) will be made by periodic payments during the course of the investigation or defense, as and when bills are received or expenses incurred.

(b)    In connection with any Registration Statement in which a Holder that is a seller of Registrable Securities is participating, each such Holder will furnish to the Company such information and affidavits as the Company reasonably requests for use in connection with any such Registration Statement or Prospectus and, to the fullest extent permitted by law, each such seller will indemnify the Company and its directors and officers and each Person who controls the Company (within the meaning of the Securities Act or the Exchange Act) against any and all losses, claims, damages, liabilities and expenses (including, without limitation, reasonable attorneys’ fees and disbursements except as limited by Section 2.7(c)) resulting from any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, Prospectus or any amendment thereof 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 not misleading, but only to the extent that such untrue statement or alleged untrue statement or omission or alleged omission is contained in any information or affidavit so furnished by such seller or any of its Seller Affiliates in writing specifically for inclusion in the Registration Statement; provided that the obligation to indemnify will be several, not joint and several, among such sellers of Registrable Securities, and the liability of each such seller of Registrable Securities will be in proportion to the amount of Registrable Securities registered by them, and, provided, further, that such liability will be limited to the net amount received by such seller from the sale of Registrable Securities pursuant to such Registration Statement; provided, however, that such seller of Registrable Securities shall not be liable in any such case to the extent that prior to the filing of any such Registration Statement or Prospectus, such seller has furnished to the Company information expressly for use in such Registration Statement or Prospectus or any amendment thereof or supplement thereto which corrected or made not misleading information previously furnished to the Company.

(c)    Any Person entitled to indemnification hereunder will (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give such notice shall not limit the rights of such Person) and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party; provided, however, that any person entitled to indemnification hereunder shall have the right to employ separate counsel and to participate in the defense of such claim, but the fees and expenses of such counsel shall be at the expense of such person unless (A) the indemnifying party has agreed to pay such fees or expenses or (B) the indemnifying party shall have failed to assume the defense of such claim and employ counsel reasonably satisfactory to such person. If such defense is not assumed by the indemnifying party as permitted hereunder, the indemnifying party will not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent will not be unreasonably withheld, conditioned or delayed). If such defense is assumed by the indemnifying party pursuant to the provisions hereof, such indemnifying party shall not settle or otherwise compromise the applicable claim unless (i) such settlement or compromise contains a full and unconditional release of the indemnified party or (ii) the indemnified party otherwise consents in writing (which consent will not be unreasonably withheld, conditioned or delayed). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim will not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any

indemnified party, a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim, in which event the indemnifying party shall be obligated to pay the reasonable fees and disbursements of such additional counsel or counsels.

(d)    Each party hereto agrees that, if for any reason the indemnification provisions contemplated by Section 2.7(a) or Section 2.7(b) are unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities or expenses (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, liabilities or expenses (or actions in respect thereof) in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party in connection with the actions which resulted in the losses, claims, damages, liabilities or expenses as well as any other relevant equitable considerations. The relative fault of such indemnifying party and indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by such indemnifying party or indemnified party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 2.7(d) were determined by pro rata allocation (even if the Holders or any underwriters or all of them were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 2.7(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or expenses (or actions in respect thereof) referred to above shall be deemed to include any legal or other fees or expenses reasonably incurred by such indemnified party in connection with investigating or, except as provided in Section 2.7(c), defending any such action or claim. Notwithstanding the provisions of this Section 2.7(d), no Holder shall be required to contribute an amount greater than the dollar amount by which the net proceeds received by such Holder with respect to the sale of any Registrable Securities exceeds the amount of damages which such Holder has otherwise been required to pay by reason of any and all untrue or alleged untrue statements of material fact or omissions or alleged omissions of material fact made in any Registration Statement or Prospectus or any amendment thereof or supplement thereto related to such sale of Registrable Securities. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Holders’ obligations in this Section 2.7(d) to contribute shall be several in proportion to the amount of Registrable Securities registered by them and not joint.

If indemnification is available under this Section 2.7, the indemnifying parties shall indemnify each indemnified party to the full extent provided in Section 2.7(a) and Section 2.7(b) without regard to the relative fault of said indemnifying party or indemnified party or any other equitable consideration provided for in this Section 2.7(d) subject, in the case of the Holders, to the limited dollar amounts set forth in Section 2.7(b).

(e)    The indemnification and contribution 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.

2.8    Transfer of Registration Rights. The registration rights of a Holder under this Agreement with respect to any Registrable Securities may be transferred or assigned to any purchaser or transferee of Registrable Securities; provided, however, that (i) such Holder shall give Parent written notice prior to the time of such transfer stating the name and address of the transferee and identifying the securities with respect to which the rights under this Agreement are being transferred; (ii) such transferee shall agree in writing, in form and substance reasonably satisfactory to Parent, to be bound as a Holder by the provisions of this Agreement; (iii) such transferee is not a direct competitor of the Company; and (iv) immediately following such transfer the further disposition of such securities by such transferee shall be restricted to the extent set forth under applicable law.

2.9    Current Public Information. With a view to making available to the Holders of Registrable Securities the benefits of Rule 144 and Rule 144A promulgated under the Securities Act and other rules and regulations of the SEC that may at any time permit a Holder of Registrable Securities to sell securities of the Company to the public without registration, the Company covenants that it will (i) use its reasonable best efforts to file in a timely manner all reports and other documents required, if any, to be filed by it under the Securities Act and the Exchange Act and the rules and regulations adopted thereunder and (ii) make available information necessary to comply with Rule 144 and Rule 144A, if available with respect to resales of the Registrable Securities under the Securities Act, at all times, all to the extent required from time to time to enable such Holder to sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by (x) Rule 144 and Rule 144A promulgated under the Securities Act (if available with respect to resales of the Registrable Securities), as such rules may be amended from time to time or (y) any other rules or regulations now existing or hereafter adopted by the SEC.

2.10    Company Obligations Regarding Transfers. In connection with any sale or transfer of Registrable Securities by any Holder, including any sale or transfer pursuant to Rule 144 and Rule 144A promulgated under the Securities Act and other rules and regulations of the SEC that may at any time permit a Holder of Registrable Securities to sell securities of the Company to the public without registration, the Company shall, to the extent allowed by law, take any and all action necessary or reasonably requested by such Holder in order to permit or facilitate such sale or transfer, including, without limitation, at the sole expense of the Company, by (i) issuing such directions to any transfer agent, registrar or depositary, as applicable, (ii) delivering such opinions to the transfer agent, registrar or depositary as are requested by the same, and (iii) taking or causing to be taken such other actions as are reasonably necessary (in each case on a timely basis) in order to cause any legends, notations or similar designations restricting transferability of the Registrable Securities held by such Holder to be removed and to rescind any transfer restrictions (other than as may apply pursuant to Section 2.3) with respect to such Registrable Securities.

2.11    No Conflict of Rights. The Company represents and warrants that it has not granted, and is not subject to, any registration rights that are superior to, inconsistent with or that in any way violate or subordinate the rights granted to the Holders hereby. The Company shall not, prior to the termination of this Agreement, grant any registration rights that are superior to, inconsistent with or that in any way violate or subordinate the rights granted to the Holders hereby.

2.12    Free Writing Prospectuses. The Company shall not permit any officer, director, underwriter, broker or any other person acting on behalf of the Company to use any free writing

prospectus (as defined in Rule 405 under the Securities Act) in connection with any registration statement covering Registrable Securities, without the prior written consent of each participating Holder and any underwriter. No Holder shall, or permit any officer, manager, underwriter, broker or any other person acting on behalf of such Holder to use any free-writing prospectus in connection with any registration statement covering Registrable Securities, without the prior written consent of the Company.

3.1    Termination. The provisions of this Agreement shall terminate and be of no further force and effect upon the earlier of (a) the first anniversary of the date of this Agreement and (b) the date when there shall no longer be any Registrable Securities outstanding; provided, however, that notwithstanding the foregoing, the obligations of the Company under Section 2.10 shall not terminate and shall remain in effect until there shall no longer be any Registrable Securities outstanding.

4.1    Notices. Any notice or other communication required or permitted hereunder shall be in writing and shall be delivered by hand, by facsimile transmission or electronic mail transmission, or by certified or registered mail, postage prepaid and return receipt requested. Notices shall be deemed to have been given upon delivery, if delivered by hand, three days after mailing, if mailed, and upon receipt of an appropriate electronic confirmation, if delivered by facsimile or electronic mail transmission.

Any party may from time to time change its address or designee for notification purposes by giving the other parties prior notice in the manner specified above of the new address or the new designee and the subsequent date upon which the change shall be effective.

(a)    This Agreement shall be constructed, interpreted and enforced in accordance with, and the respective rights and obligations of the parties shall be governed by, the laws of the State of Delaware without regard to principles of conflicts of law.

(b)    All actions and proceedings for the enforcement of or based on, arising out of or relating to this Agreement shall be heard and determined exclusively in the Delaware Court of Chancery (or, only if the Delaware Court of Chancery declines to accept jurisdiction over the particular matter, any other court of the State of Delaware, or any federal court sitting in the State of Delaware), and each of the parties hereto hereby (i) irrevocably submits to the exclusive jurisdiction of such courts (and, in the case of appeals, appropriate appellate courts therefrom) in any such action or proceeding, (ii) irrevocably waives the defense of an inconvenient forum to the maintenance of any such action or proceeding, (iii) agrees that it shall not bring any such action in any court other than the Court of Chancery of the State of Delaware (or, only if the Delaware Court of Chancery declines to accept jurisdiction over the particular matter, any other court of the State of Delaware, or any federal court sitting in the State of Delaware), and (iv) irrevocably consents to service of process by first class certified mail, return receipt requested, postage prepaid, to the address at which Member or Parent, as the case may be, is to receive notice in accordance with Section 4.2. The parties hereto agree that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by applicable law.

(c)    Each of the parties hereto hereby irrevocably waives any and all rights to trial by jury in any legal proceeding arising out of or related to this Agreement.

4.3    No Third-Party Beneficiaries. This Agreement is for the sole benefit of the parties hereto and their respective successors and permitted assigns and nothing herein, express or implied, is intended to or shall confer upon any other Person any legal or equitable right, benefit or remedy of any nature whatsoever, under or by reason of this Agreement; provided, however, the parties hereto hereby acknowledge that the Persons set forth in Section 2.3 and Section 2.7 are express third-party beneficiaries of the obligations of the parties hereto set forth in Section 2.3 and Section 2.7, respectively.

4.4    Successors and Assigns. Except as otherwise expressly provided herein, this Agreement shall be binding upon and benefit the Company, each Holder and their respective successors and assigns. The Company shall not, directly or indirectly, enter into any merger, consolidation or reorganization in which the Company shall not be the surviving entity unless the surviving entity shall, prior to such merger, consolidation or reorganization, agree in writing to assume the obligations of the Company under this Agreement, and for that purpose references hereunder to “Registrable Securities” shall be deemed to include the common equity interests or other securities, if any, which the Holders would be entitled to receive in exchange for Registrable Securities under any such merger, consolidation or reorganization, provided that, to

the extent the Holders receive securities that are by their terms convertible into common equity interests of the issuer thereof, then any such common equity interests as are issued or issuable upon conversion of said convertible securities shall be included within the definition of “Registrable Securities.”

4.5    Counterparts. This Agreement may be executed by the parties in separate counterparts (including by means of executed counterparts delivered via facsimile or other electronic means), each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

4.6    Severability. In case any provision in this Agreement shall be held invalid, illegal or unenforceable in any respect for any reason, the validity, legality and enforceability of any such provision in every other respect and the remaining provisions shall not in any way be affected or impaired thereby.

(a)    No failure or delay on the part of the Company or any Holder in exercising any right, power or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, power or remedy preclude any other or further exercise thereof or the exercise of any other right, power or remedy. The remedies provided for herein are cumulative and are not exclusive of any remedies that may be available to the Company or any Holder at law or in equity or otherwise.

(b)    Any provision of this Agreement may be amended or waived if, but only if, such amendment or waiver is in writing and is signed by the Company and the Required Holders; provided, however, that, so long as each of First Reserve or Ziff, each together with its Affiliates, continues to own 20% or more of the Registrable Securities acquired by it at the closing of the transactions contemplated in the Merger Agreement, any such amendment or waiver shall require the written consent of First Reserve and/or Ziff, as applicable.

4.8    Entire Agreement. This Agreement and the other writings referred to herein or therein or delivered pursuant hereto or thereto, contain the entire agreement between the Holders and the Company with respect to the subject matter hereof and supersede all prior and contemporaneous arrangements or understandings with respect thereto.

(a)    Each Holder shall have all rights and remedies reserved for such Holder pursuant to this Agreement and all rights and remedies which such Holder has been granted at any

time under any other agreement or contract and all of the rights which such Holder has under any law or equity. Any Person having any rights under any provision of this Agreement will be entitled to enforce such rights specifically, to recover damages by reason of any breach of any provision of this Agreement and to exercise all other rights granted by law or equity.

(b)    The parties hereto recognize and agree that money damages may be insufficient to compensate the Holders of any Registrable Securities for breaches by the

Company of the terms hereof and, consequently, that the equitable remedies of injunctive relief and of specific performance of the terms hereof will be available in the event of any such breach. If any action should be brought in equity to enforce any of the provisions of this Agreement, none of the parties hereto shall raise the defense that there is an adequate remedy at law..

4.10    Negotiated Agreement. This Agreement was negotiated by the parties with the benefit of legal representation, and any rule of construction or interpretation otherwise requiring this Agreement to be construed or interpreted against any party shall not apply to the construction or interpretation hereof.
