4.Right of First Offer.

     (a) Subject to the terms of thisSection 4, each Stockholder hereby unconditionally and irrevocably grants to each other Applicable Stockholder a right of first offer to purchase any or all shares of Capital Stock that such Stockholder may propose to Transfer (whether or not as a the result of an unsolicited offer received by such Stockholder), other than to a Specified Transferee of such Stockholder and other than pursuant to a Transfer in accordance withSection 6.

     (b) If a Stockholder desires to Transfer all or a portion of its shares of Capital Stock to any Person other than a Specified Transferee of such Stockholder, and other than in accordance withSection 6, such Stockholder (the “Selling Stockholder”) shall first deliver written notice of its desire to do so (the “Offer Notice”) to the Corporation and each of the other Applicable Stockholders (the “Non-Selling Stockholders”).

Such option shall be exercised by delivery by such Non-Selling Stockholder (a “ROFO Purchasing Stockholder”) of written notice to the Selling Stockholder, which shall state the number of Offered Shares that such ROFO Purchasing Stockholder intends to purchase and shall include a representation letter

certifying that such ROFO Purchasing Stockholder is an “accredited investor” within the meaning of Rule 501 under the Securities Act. Any written notice delivered by a ROFO Purchasing Stockholder to the Selling Stockholder exercising the option set forth under thisSection 4(c) shall constitute an irrevocable commitment by such ROFO Purchasing Stockholder to purchase up to the maximum number of Offered Shares for which such ROFO Purchasing Stockholder has indicated its intention to purchase in such written notice in accordance with the Offer Notice and thisSection 4. Any Non-Selling Stockholder that fails to provide such written notice to the Selling Stockholder prior to the expiration of the Non-Selling Stockholder Option Period shall forfeit its right to purchase any of the Offered Shares.

     (d) In the event that the number of Offered Shares that the ROFO Purchasing Stockholders elect to purchase is greater than the actual number of Offered Shares, then each ROFO Purchasing Stockholder shall be entitled to purchase a pro rata portion of the Offered Shares, equal to the number of Offered Shares multiplied by such ROFO Purchasing Stockholder’s Applicable Ownership Percentage, for the Offered Price and on the Offered Terms.

     (e) The ROFO Purchasing Stockholders shall not have any right to purchase any of the Offered Shares hereunder unless all of the Offered Shares are purchased pursuant to thisSection 4. If the ROFO Purchasing Stockholders exercise their options to purchase all of the Offered Shares, each such ROFO Purchasing Stockholder shall, following delivery of written notices to the Selling Stockholder for such election, cooperate with the Selling Stockholder, and the Selling Stockholder shall cooperate with each ROFO Purchasing Stockholder, and each of them shall use commercially reasonable efforts, to consummate the purchase and sale of the Offered Shares that such ROFO Purchasing Stockholder has elected to purchase, as promptly as practicable and, in any event, within thirty (30) calendar days following the end of the Non-Selling Stockholder Option Period (subject to such extensions as are reasonably necessary to obtain any third party approvals, including approvals from governmental entities, as may be necessary to consummate such purchase and sale), for the Offered Price and on the Offered Terms. If the Non-Selling Stockholders do not exercise their options to purchase all of the Offered Shares within the Non-Selling Stockholder Option Period, then all options of the Non-Selling Stockholders to purchase the Offered Shares, whether exercised or not, shall terminate.

     (f) Upon the earlier of (i) the expiration of the Non-Selling Stockholder Option Period in which period the Non-Selling Stockholders do not deliver written notices indicating their intent, in the aggregate, to purchase all of the Offered Shares, and (ii) delivery of written notices to the Selling Stockholder from all the Non-Selling Stockholders indicating their intent, in the aggregate, to purchase less than all of the Offered Shares (the date of such earlier occurrence, the “ROFO Ending Date”), the Selling Stockholder shall have the right, exercisable for a period of ninety (90) calendar days from the ROFO Ending Date (the “Unrestricted Period”), but subject toSection 5, to Transfer all or a portion of the Offered Shares to any Person (but subject toSection 8) for a price per share of Capital Stock that is not less than the Offered Price and on material terms and conditions that are not more favorable to such Person than the Offered Terms;provided, that a Selling Stockholder shall be deemed to have Transferred its Offered Shares during the Unrestricted Period if it, during the Unrestricted Period, has irrevocably entered into a bona fide binding agreement to Transfer the Offered Shares to any Person; provided further, that the closing of such Transfer must occur within sixty (60) calendar days of the execution of such bona fide binding agreement, which period may be extended by the

9

Selling Stockholder by up to an additional ninety (90) calendar days as required to obtain any required regulatory approvals. If the Selling Stockholder ever wishes to Transfer the Offered Shares, for a price per share of Capital Stock that is less than the Offered Price or on material terms and conditions that are more favorable than the Offered Terms, or if the Selling Stockholder wishes to Transfer the Offered Shares following the expiration of the Unrestricted Period, then the Selling Stockholder shall be required to first comply with thisSection 4 anew.

     (g) Notwithstanding anything to the contrary herein, with respect to each Stockholder Group, any notice to be delivered under thisSection 4 to members of such Stockholder Group shall be delivered to the applicable Stockholder and it shall be the responsibility of such Stockholder to coordinate the participation of the members of its Stockholder Group with respect to the procedures set forth in thisSection 4. For the sake of clarity, all references in thisSection 4 to a Stockholder shall, when referring to members of a Stockholder Group, refer to all members of such group as one. Accordingly, all notifications to be made pursuant to thisSection 4 shall be delivered to and sent by each Stockholder on behalf of its Stockholder Group.

5.Tag-Along Right.

     (a) If, after giving effect to the right of first offer of the Non-Selling Stockholders set forth underSection 4 and nevertheless subject toSection 4(f), the Selling Stockholder (or, if it acted together with its Specified Transferees pursuant toSection 4, such Selling Stockholder together with its Specified Transferees) intends to Transfer shares of Capital Stock, in an amount that equals or exceeds twenty percent (20%) or more of the then outstanding Applicable Shares, to any Person other than a Specified Transferee (the “Third Party Purchaser”) during the Unrestricted Period (except in the event the Selling Stockholder(s) exercises its right, if applicable, underSection 6), the Selling Stockholder shall, on behalf of itself and its Specified Transferees, first deliver written notice of such intent (the “Tag-Along Notice”) to each of the Non-Selling Stockholders. The Tag-Along Notice must specify: (i) the number of Offered Shares that the Third Party Purchaser shall purchase (the “Tag-Along Shares”); (ii) the consideration per share of Capital Stock to be paid by the Third Party Purchaser for the Tag-Along Shares (expressed as a value in cash, the “Tag-Along Price”); and (iii) all other material terms and conditions for the proposed transaction (the “Tag-Along Terms”).

     (b) Each Non-Selling Stockholder shall have the option, exercisable for a period of five (5) calendar days following delivery of the Tag-Along Notice (the “Tag-Along Decision Period”) by written notice to the Selling Stockholder, to sell a number of its shares of Capital Stock up to its Tag-Along Portion to the Third Party Purchaser for the Tag-Along Price and on the Tag-Along Terms. Any written notice delivered by such a Non-Selling Stockholder (a “Participating Stockholder”) to the Selling Stockholder exercising the option set forth under thisSection 5(b) shall constitute an irrevocable commitment by such Non-Selling Stockholder to sell the number of shares of Capital Stock (up to its Tag-Along Portion) for which such Non-Selling Stockholder has indicated its intention to sell in such written notice in accordance with the Tag-Along Notice and thisSection 5(b). For purposes of this Agreement, “Tag-Along

10

Portion” shall mean, with respect to any Participating Stockholder, a pro rata portion of the Tag-Along Shares equal to the number of Tag-Along Shares multiplied by such Participating Stockholder’s Applicable Ownership Percentage.

     (c) Upon the earlier of (i) the expiration of the Tag-Along Decision Period or (ii) delivery of written notices to the Selling Stockholder from all the Non-Selling Stockholders responding to the Tag-Along Notice, the Selling Stockholder shall have the right to Transfer an amount equal to the Tag-Along Shares minus the number of shares of Capital Stock with respect to which Participating Stockholders elected to participate in the sale pursuant to thisSection 5, subject to compliance withSection 8.

     (d) Each Participating Stockholder that elects, pursuant to thisSection 5, to sell its shares of Capital Stock to the Third Party Purchaser shall, following delivery of written notice to the Selling Stockholder indicating such election, cooperate with the Selling Stockholder, and the Selling Stockholder shall cooperate with such Participating Stockholder, and each of them shall use commercially reasonable efforts, to cause the shares of Capital Stock of the Selling Stockholder and all the Participating Stockholders, representing altogether the Tag-Along Shares, to be sold to the Third Party Purchaser, as promptly as practicable, for the Tag-Along Price and on the Tag-Along Terms. If the Third Party Purchaser is unwilling to purchase from a Participating Stockholder the shares of Capital Stock such Participating Stockholder has elected to sell as contemplated hereby, then the Selling Stockholder shall not sell any of its shares of Capital Stock to the Third Party Purchaser unless the Selling Stockholder purchases from such Participating Stockholder, at the Tag-Along Price and on terms equivalent to the Tag-Along Terms, at the same time all of such shares of Capital Stock.

     (e) Notwithstanding anything to the contrary herein, with respect to each Stockholder Group, any notice to be delivered under thisSection 5 to members of such Stockholder Group shall be delivered to the applicable Stockholder and it shall be the responsibility of such Stockholder to coordinate the participation of the members of its Stockholder Group with respect to the procedures set forth in thisSection 5. For the sake of clarity, all references in thisSection 5 to a Stockholder shall, when referring to members of a Stockholder Group, refer to all members of such group as one. Accordingly, all notifications to be made pursuant to thisSection 5 shall be delivered to and sent by each Stockholder on behalf of its Stockholder Group.

     (f) ThisSection 5 shall not apply to Transfers of shares of Common Stock made pursuant to the Initial Public Offering.

Capital Stock owned by the Compellors, then the same portion of the shares of Capital Stock owned or held by the Compelled Stockholders as the Compellors are selling) to such Drag-Along Purchaser(s) for the same consideration (or, if there is a choice as to the form of consideration, then each Compelled Stockholder shall have the same choice as the Compellors, provided that, in the event that any securities are part of the consideration payable, any Stockholder that is not an “accredited investor” within the meaning of Rule 501 under the Securities Act may, in the sole discretion of the Board of Directors of the Corporation (the “Board”), receive, and hereby agrees to accept, in lieu of securities, cash consideration with an equivalent value to such securities as reasonably determined by the Board) and otherwise on the same terms and conditions upon which the Compellors sell their shares of Capital Stock, subject to thisSection 6.

     (b) (i) The Compellors shall provide a written notice (the “Drag-Along Notice”) of such Drag-Along Offer to each of the Compelled Stockholders, with a copy to the Corporation, not later than the day after the date of acceptance of the Drag-Along Offer by the Drag-Along Purchaser(s). The Drag-Along Notice shall contain written notice of the exercise of the rights of the Compellors pursuant toSection 6(a) setting forth the consideration to be paid by the Drag-Along Purchaser(s) and all other material terms and conditions of the Drag-Along Offer, as well as a copy of the Drag-Along Offer, and definitive documentation of the transaction, if available. Within ten (10) Business Days following the date the Drag-Along Notice is given, each of the Compelled Stockholders shall deliver to the Compellors a special irrevocable power-of-attorney authorizing the Compellors, on behalf of such Compelled Stockholder, to sell or otherwise dispose of such shares of Capital Stock pursuant to the terms of the Drag-Along Offer and to take all such actions as shall be necessary or appropriate in order to consummate such sale or disposition.

          (ii) Promptly after the consummation of the sale of shares of Capital Stock of the Compellors and the Compelled Stockholders to the Drag-Along Purchaser(s) pursuant to the Drag-Along Offer, but in no event more than two (2) Business Days thereafter, the Compellors shall remit to the Compelled Stockholders the total sales price of the shares of Capital Stock of the Compelled Stockholders sold pursuant thereto less a pro rata portion of the expenses (including reasonable legal expenses) incurred by the Compellors in connection with such sale.

          (iii) If, at the end of the 180-day period following the giving of the Drag-Along Notice, the Compellors shall not have completed the sale of all the Controlling Shares and the shares of Capital Stock of the Compelled Stockholders, then no Stockholder shall have any obligation with respect to such Drag-Along Offer; provided, that the provisions of thisSection 6 shall apply to any subsequent Drag-Along Offer.

          (iv) Except as expressly provided in thisSection 6, the Compellors shall have no obligation to any Compelled Stockholder with respect to the sale or other disposition of any shares of Capital Stock owned by the Compelled Stockholder, and in particular, the Compellors shall have no obligation to any Compelled Stockholder to consummate any Drag Along Offer (it being understood that any and all such decisions shall be made by the Compellors in their sole discretion). In the event that the Drag-Along Offer is not consummated by the Compellors, the Compelled Stockholders shall not be entitled to sell or otherwise dispose of shares of Capital Stock directly to any third party or parties pursuant to such Drag-Along Offer (it being understood that all such sales and other dispositions shall be made only on the terms and pursuant to the procedures set forth inSections3,4,5,6,7 and8).

12

     (c) In furtherance of, and not in limitation of the foregoing, in connection with any compelled sale, each Stockholder will (i) raise no objections in its capacity as a stockholder of the Corporation, will consent to, vote for and raise no objections to such transaction or the process pursuant to which it was arranged, and waive dissenting rights, if any, and (ii) execute all documents containing such terms and conditions as those executed by other Stockholders that are reasonably necessary to effect the transaction;provided,however, that (A) no Compelled Stockholder shall be required to enter into a non-compete or non-solicitation or no-hire provision, a provision providing for the licensing of intellectual property or the delivery of any products or services, or any other provision that is not a strictly financial term related directly to the sale of the shares of Capital Stock, (B) the liability of the Stockholders is several and not joint, (C) no Compelled Stockholder shall have any liability for any breaches of the representations, warranties or covenants of any other Stockholder, (D) any obligations and/or liabilities of Compelled Stockholders under the agreement governing such transaction and any related escrow agreement shall be borne pro rata among such Stockholders based on the proceeds and assets payable to such Stockholders in such transaction (other than any such obligations that relate specifically to a particular Stockholder’s shares of Capital Stock, which obligations shall be borne solely by such Stockholder) and shall in no event exceed the actual proceeds and assets received by such Compelled Stockholder in such transaction, (E) no Compelled Stockholder shall be required to make any representations or warranties or covenants in connection with such transaction except with respect to (1) such Compelled Stockholder’s ownership of its shares of Capital Stock, (2) subject to the provisions of clauses (B) and (C) above, customary security holder indemnities for breaches of representations, warranties and covenants, (3) such Compelled Stockholder’s ability to convey title to its shares of Capital Stock free and clear of liens, (4) such Compelled Stockholder’s ability to enter in the transaction and such Compelled Stockholder’s power and organization and (5) customary and reasonable covenants regarding confidentiality, publicity and similar matters and (F) if any Stockholder is given an option as to the form of consideration to be received, all other Stockholders shall be given the same option on the same terms;providedthat, in the event that any securities are part of the consideration payable, each Stockholder that is not an “accredited investor” within the meaning of Rule 501 under the Securities Act may, in the sole discretion of the Board, receive, and hereby agrees to accept, in lieu of securities, cash consideration with an equivalent value to such securities as reasonably determined by the Board.

     (d) Notwithstanding anything in thisSection 6 to the contrary, if the Compellors or any of their respective Representatives, directly or indirectly, receive any consideration from the Drag-Along Purchaser(s) or any of its Affiliates in connection with a compelled sale other than the consideration that is received by all the Stockholders on a pro rata basis as part of the compelled sale, then the Compellors shall cause each of the Compelled Stockholders to receive their pro rata share, determined by reference to the respective amounts of consideration otherwise payable to each Stockholder (including the Compellors) as part of the compelled sale, of such consideration.

     (e) ThisSection 6 shall not apply to Transfers of shares of Common Stock made pursuant to the Initial Public Offering.

7.Preemptive Rights.

     (a) If the Corporation (or any of its subsidiaries) proposes to issue or sell any shares of Capital Stock or other equity securities (including any securities exchangeable or exercisable for, or convertible into, shares of Capital Stock or other equity securities), other than Excluded Shares, (collectively, “Offered Securities”), which proposal has been approved by the Stockholders as a Super-Majority Action, the Corporation shall first deliver written notice of its proposal to do so (the “Purchase Right Notice”) to each of the Applicable Stockholders. The Purchase Right Notice must: (i) identify the name and address of each Person (if known) to which the Corporation or such subsidiary proposes to issue or sell Offered Securities; (ii) specify the number of Offered Securities (other than Excluded Shares) that the Corporation or such subsidiary proposes to issue or sell (the “Issued Shares”); (iii) describe the consideration per Offered Security for the Issued Shares (expressed as a value in cash, the “Issued Price”); (iv) describe the material terms and conditions upon which the Corporation or such Subsidiary proposes to issue or sell the Issued Shares (the “Issued Terms”); and (v) irrevocably offer to issue or sell to each Applicable Stockholder any number of Issued Shares of Capital Stock up to a pro rata portion of the Issued Shares, based on their Applicable Ownership Percentages, for the Issued Price and on the Issued Terms and in accordance with thisSection 7(a).

          (i) Each Applicable Stockholder shall have an option, exercisable for a period of fifteen (15) calendar days from the date of delivery of the Purchase Right Notice (the “Purchase Period”), to purchase a pro rata portion of the Issued Shares equal to the number of Issued Shares multiplied by such Stockholder’s Applicable Ownership Percentage, for the Issued Price and on the Issued Terms (the “Purchase Right”). The Purchase Right shall be exercised by delivery by such Stockholder (a “Purchasing Stockholder”) of written notice to the Corporation, which shall state the number of Issued Shares to be purchased by such Purchasing Stockholder and shall include a representation letter certifying that such Purchasing Stockholder is an “accredited investor” within the meaning of Rule 501 under the Securities Act. Any written notice delivered by a Purchasing Stockholder to the Corporation exercising the option set forth under thisSection 7(a)(i) shall constitute an irrevocable commitment by such Purchasing Stockholder to purchase the number of Issued Shares specified in such written notice in accordance with the Purchase Right Notice and thisSection 7. The failure of a Stockholder to timely deliver the notice hereunder shall be deemed a waiver of such Stockholder’s right to purchase the Issued Shares.

          (ii) If the options to purchase the Issued Shares have been exercised by some, but not all of the Stockholders by the end of the Purchase Period, then, immediately after the Purchase Period, the Corporation shall deliver written notice to those Purchasing Stockholders (the “Exercising Stockholders”) who fully exercised their Purchase Rights (the “Exercising Stockholder Notice”) specifying the number, if any, of Issued Shares that have not been purchased by the Stockholders (the “Remaining Issued Shares”).

          (iii) Each Exercising Stockholder shall have an option, exercisable for a period of five (5) calendar days from the date of delivery of the Exercising Stockholder Notice (the “Exercising Stockholder Option Period”) to elect to purchase all or a portion of the Remaining Issued Shares for the Issued Price and on the Issued Terms. Such option shall be exercised by delivery by such Exercising Stockholder of written notice to the Corporation, which shall state the number of Remaining Issued Shares that such Exercising Stockholder intends to

14

purchase and shall include a written notice containing the same information as described inSection 7(a)(i). Any Exercising Stockholder that fails to provide such written notice to the Corporation prior to the expiration of the Exercising Stockholder Option Period shall forfeit its right to purchase any of the Remaining Issued Shares.

          (iv) In the event that the number of Remaining Issued Shares that the Exercising Stockholders elect to purchase is greater than the actual number of Remaining Issued Shares, then each Exercising Stockholder shall be entitled to purchase a pro rata portion of the Remaining Issued Shares, equal to the number of Remaining Issued Shares multiplied by such Exercising Stockholder’s Applicable Ownership Percentage, for the Issued Price and on the Issued Terms.

          (v) Each Purchasing Stockholder shall purchase from the Corporation, and the Corporation shall issue or sell to such Purchasing Stockholder, the number of Issued Shares that such Purchasing Stockholder elected to purchase in accordance with thisSection 7 (including in its capacity as an Exercising Stockholder) for the Issued Price and on the Issued Terms on (A) the date of the closing of the issuance of the Issued Shares described in the Purchase Right Notice delivered by the Corporation pursuant to thisSection 7(a) or (B) such other date as may be agreed in writing by the Corporation and such Purchasing Stockholder.

          (vi) If a Stockholder does not exercise its Purchase Right during the Purchase Period, then such Stockholder’s Purchase Right with respect to such Issued Shares shall terminate.

     (b) Upon the earlier of (i) the expiration of the Exercising Stockholder Option Period or, ifSection 7(a)(iii) above does not apply, the expiration of the Purchase Period, and (ii) delivery of written notices to the Corporation from all the Applicable Stockholders indicating their intent, in the aggregate, to purchase less than all of the Issued Shares (the date of such earlier occurrence, the “Ending Date”), the Corporation shall have the right, exercisable for a period of ninety (90) calendar days from the Ending Date (the “Issuance Period”), to issue or sell all or a portion of the Issued Shares that the Applicable Stockholders have elected not to purchase (the “Final Remaining Issued Shares”) to any Person for a price per share of Capital Stock that is not less than the Issued Price and on material terms and conditions that are not more favorable to such other Person than the Issued Terms;provided, that the Corporation shall be deemed to have issued or sold the Final Remaining Issued Shares during the Issuance Period if it, during the Issuance Period, has irrevocably entered into a bona fide binding agreement to issue or sell the Final Remaining Issued Shares to any Person;provided further, that the closing of such Transfer must occur within sixty (60) calendar days of the execution of such bona fide binding agreement, which period may be extended by the Corporation by up to an additional sixty (60) calendar days as required to obtain regulatory approvals. If the Corporation ever wishes to issue or sell the Final Remaining Issued Shares for a price per share of Capital Stock that is less than the Issued Price or on material terms and conditions that are more favorable to the purchaser than the Issued Terms, or if the Corporation wishes to issue or sell the Final Remaining Issued Shares following the expiration of the Issuance Period, the Corporation shall be required first to comply with thisSection 7 anew.

     (c) The Purchase Rights established by thisSection 7 shall have no application to any of the following Offered Securities (collectively, the “Excluded Shares”):

15

          (i) shares of Capital Stock issued in connection with any share split, share dividend, share division or recapitalization by the Corporation, pursuant to which all holders of shares of Capital Stock are treated similarly;

          (ii) shares of Capital Stock, options to purchase shares of Capital Stock or other equity interests of the Corporation in connection with an Incentive Plan approved by the Stockholders as a Simple-Majority Action pursuant toSection 10(a)(ix) or a Super-Majority Action pursuant toSection 10(b)(xiii), or shares of Common Stock issuable upon conversion of Class A Common Stock and Class B Common Stock;

          (iii) equity securities of any subsidiary of the Corporation issued to the Corporation or any wholly owned subsidiary of the Corporation; and

          (iv) shares of capital stock or other equity securities issued for consideration other than cash in connection with business acquisitions, mergers or strategic partnerships or alliances approved by the Stockholders as a Super-Majority Action pursuant toSection 10(b)(i) orSection 10(b)(iii), as the case may be.

     (d) Notwithstanding anything to the contrary herein, with respect to each Stockholder Group, any notice to be delivered under thisSection 7 to members of such Stockholder Group shall be delivered to the applicable Stockholder and it shall be the responsibility of such Stockholder to coordinate the participation of the members of its Stockholder Group with respect to the procedures set forth in thisSection 7. For the sake of clarity, all references in thisSection 7 to a Stockholder shall, when referring to members of a Stockholder Group, refer to all members of such group as one. Accordingly, all notifications to be made pursuant to thisSection 7 shall be delivered to and sent by each Stockholder on behalf of its Stockholder Group.

     (e) ThisSection 7 shall not apply to Transfers of shares of Common Stock made pursuant to the Initial Public Offering, including the issuance of shares of Common Stock by the Corporation.

8. General Restrictions on Transfer.

     (a) Notwithstanding anything to the contrary contained in this Agreement, no Transfer of shares of Capital Stock by a Stockholder or issuance of shares of Capital Stock by the Corporation shall be made if such Transfer or issuance is to a Person who is (A) a Competitor of the Corporation or any subsidiary thereof, (B) a customer of the Corporation or any subsidiary, or (C) a rare earth trading house;provided, that the Corporation and the Stockholders agree that Traxys’ business operations as they exist as of the date hereof shall not be deemed competitive with the Corporation or any subsidiary. Subject to thisSection 8(a) and the remainder of thisSection 8, Stockholders may Transfer shares of Capital Stock to their Specified Transferees.

     (b) Notwithstanding anything to the contrary contained in this Agreement, no Transfer of shares of Capital Stock by a Stockholder or issuance of shares of Capital Stock by the Corporation shall be made if such Transfer or issuance (A) would violate any state or federal securities laws, (B) would require the Corporation to register as an investment company under the Investment Company Act, (C) would require the Corporation to register as an investment adviser under state or federal securities laws, or (D) other than in connection with the Initial

16

Public Offering, would require the Corporation to register any of its securities under Section 12 of the Exchange Act.

     (c) Notwithstanding anything to the contrary contained in this Agreement, no Stockholder may Transfer any shares of Capital Stock to a transferee as permitted by this Agreement (a “Permitted Transferee”), unless such Permitted Transferee (other than a Permitted Transferee that purchases shares of Capital Stock in connection with a compelled sale pursuant toSection 6) agrees to execute a Joinder Agreement in substantially the form attached hereto asExhibit A.

     (d) Additional shares of Capital Stock may be issued to Persons other than members of a Stockholder Group only if approved by the Stockholders as a Super-Majority Action pursuant toSection 10(b)(v).

     (e) Indirect Transfers of Shares. Each Stockholder agrees that it shall not take any actions, or permit any actions to be taken by its direct or indirect equity owners, that are intended to circumvent the provisions ofSections 4,5,6,7 and8 including any such actions to effect the indirect Transfer of shares of Capital Stock without being subject to the provisions ofSections 4,5,6,7 and8.

Subject to thisSection 9(a),Section 9(b) andSection 10(b)(vi), each party shall take all action within its respective power, including the voting of its shares of Capital Stock or execution of consents, required to set the number of Directors on the Corporation’s Board at nine (9) and to cause the election of the following natural persons to the Board as Directors of the Corporation (the “Directors”) who have been nominated by thisSection 9(a):

          (ii) For as long as RCF (together with its Specified Transferees) maintains an Applicable Ownership Percentage of at least twenty percent (20%), it shall have the right to nominate two (2) Directors (each, an “RCF Director”). If the Applicable Ownership Percentage of RCF (together with its Specified Transferees) is less than twenty percent (20%) but at least ten percent (10%), RCF shall have the right to nominate one (1) RCF Director and the number of directors shall be decreased by one (1) if an Independent Director has not been appointed in his or her place. If the Applicable Ownership Percentage of RCF (together with its Specified Transferees) falls below twenty percent (20%) but is at least ten percent (10%), one of such two (2) Directors will be deemed immediately to have been removed from the Board;provided, that RCF shall designate which Director is so removed. If the Applicable Ownership Percentage of RCF (together with its Specified Transferees) falls below ten percent (10%), the then remaining RCF Director shall be deemed immediately to have been removed from the Board and the number of directors shall be decreased by one (1).

          (iii) For as long as Pegasus (together with its Specified Transferees) maintains an Applicable Ownership Percentage of at least ten percent (10%), it shall have the right to nominate one (1) Director. If the Applicable Ownership Percentage of Pegasus (together with its

          (v) Subject toSection 9(a)(vi), the individuals nominated as of the Effective Date by RCF to be the RCF Directors, by Pegasus to be its Director and by Traxys to be its Director are set forth onExhibit B attached hereto.

          (vi) Unless a majority of the Directors appointed pursuant to thisSection 9(a) decide that a particular Chief Executive Officer of the Corporation should not serve as a Director, the Chief Executive Officer of the Corporation shall serve at all times as a Director.

     (b) If any of RCF, Pegasus or Traxys decline to nominate a Director to which they are entitled underSection 9(a), the size of the Board shall be reduced by the number of director positions for which no nomination has been made until such time as a nomination is made by such Stockholder.

     (c) Observer Rights. Each of RCF and Pegasus, for so long as it (together with its Specified Transferees) maintains an Applicable Ownership Percentage of at least five percent (5%), may elect to designate, and Traxys, for so long as Traxys and MP (together with their Specified Transferees) maintain an aggregate Applicable Ownership Percentage of at least five percent (5%), may elect to designate, in each case by written notice to the Corporation, a non-director representative to attend all meetings of the Board in a non-voting observer capacity. In this respect, the Corporation shall give such representatives copies of all notices, minutes, consents, and other materials that it provides to its Directors at the same time and in the same manner as provided to such Directors. Such a representative shall be permitted to disclose any information learned thereby to the Stockholder which appointed such representative and such Stockholder’s Affiliates for purposes of managing such Stockholder’s investment in the Corporation.

     (d) Each Director, other than the Chief Executive Officer of the Corporation and other than each Independent Director, shall serve solely in the discretion of the Stockholder that nominated such Director, and subject to the terms ofSection 9(a) and thisSection 9(d), may be removed only by such Stockholder, in the discretion of such Stockholder from time to time. Each Stockholder shall notify the Corporation and the other Stockholders in writing of its nomination of any individual to serve as a Director (other than those individuals nominated onExhibit B as of the Effective Date, notice of which is hereby acknowledged by each Stockholder) or the removal of an individual as a Director, or if it intends not to nominate an individual to fill a designated Director position. Notwithstanding anything in the foregoing to the contrary, the Board shall have the right to remove any Director nominated by a Stockholder, upon the unanimous vote of all Directors other than those nominated by such Stockholder, in the event that such Director has materially violated any material provision of this Agreement, the Act or

18

any federal or state securities law. A Stockholder whose nominated Director is removed pursuant to thisSection 9(d) shall, subject to the terms ofSection 9(a), have the right to nominate a replacement for such removed Director (such person, a “Substitute Director”). Each party agrees to take all action within its power, including (i) requesting its respective director nominees, as the first order of business at the first meeting of the Board after a Substitute Director has been duly nominated, to vote to elect any designated substitute Director as a director in place of a Director who has been removed and (ii) if necessary, voting its Capital Stock or executing consents to cause the election of such Substitute Director as soon as practicable following his or her nomination.

     (e) In the event that a Director is unable to attend or participate in any meeting of the Board or any committee thereof, the Stockholder that nominated such Director may appoint an alternate to attend such meetings and to participate in the deliberations of such meetings. Such alternate will be permitted to vote on behalf of the absent Director and will be considered an attendee of any meetings for the purposes of constituting a quorum.

Each Stockholder shall be responsible for any breach of thisSection 12(b) by any of its Representatives and agrees to use commercially reasonable efforts to cause its Representatives to treat all Confidential Information in the same manner as such Stockholder would generally treat its own confidential, non-public information.

     (b) Interested Transactions. Traxys will have a right of first refusal (the “Traxys Right of First Refusal”) to match the terms of any proposed third party marketing agreement with the Corporation or any subsidiary of the Corporation (other than third party marketing arrangements with Sumikin Molycorp, Inc., Sumitomo Metal Industries, Ltd. or any of their respective subsidiaries), which shall remain in effect until the earlier of (i) September 30, 2018, (ii) the date upon which Traxys is no longer a Stockholder and (iii) the Initial Public Offering, at which time the Traxys Right of First Refusal shall terminate. The approval of the Stockholders

24

will not be required for the Corporation or any subsidiary of the Corporation to enter into a marketing agreement with Traxys pursuant to the Traxys Right of First Refusal and the procedures set forth in thisSection 13(b). For the duration of the period of the Traxys Right of First Refusal, such right shall be effected as follows:

          (i) If the Corporation or any subsidiary of the Corporation has entered into negotiations and proposes to enter into a third party marketing agreement (other than agreements with Sumikin Molycorp, Inc., Sumitomo Metal Industries, Ltd. or any of their respective subsidiaries), the Corporation shall first deliver written notice of its desire to do so (the “Marketing Agreement Notice”) to Traxys, which notice shall specify (A) the Corporation’s or such subsidiary’s bona fide intention to enter such marketing agreement, (B) the identity of such third party and (C) the material terms and conditions of the proposed marketing agreement, including, if it is in existence, the latest draft of such marketing agreement (the “Third Party MA”).

          (ii) Traxys shall then have the option to enter into a marketing agreement with the Corporation or such subsidiary in lieu of the Third Party MA on the material terms and conditions set forth in the Marketing Agreement Notice or on terms and conditions more favorable to the Corporation or such subsidiary. Traxys must exercise such option if it so desires, no later than ten (10) calendar days after the Marketing Agreement Notice has been delivered to Traxys (the “Traxys Option Period”), by written notice to the Corporation. If Traxys so exercises such option, the Corporation or such subsidiary and Traxys will then prepare and execute a marketing agreement on the terms and conditions set forth in the Third Party MA as soon as reasonably practicable thereafter. If Traxys fails to provide such written notice to the Corporation prior to the expiration of the Traxys Option Period or elects not to exercise its option, then the Corporation or such subsidiary shall be free for a period of ninety (90) calendar days to enter into a marketing agreement with a third party on terms and conditions that are, in the aggregate, not more favorable to such third party than those set forth in the Marketing Agreement Notice. If the Corporation or such subsidiary shall not have entered into such Third Party MA within such period, then the Corporation or such subsidiary shall again be subject to the procedures set forth in thisSection 13(b).

     (c) Other Activities of the Stockholders. Each of the Stockholders and any Person employed by, related to or in any way affiliated with any Stockholder (the “Permitted Persons”) may have other business interests and may engage in any business or trade, profession, employment or activity whatsoever (regardless of whether any such activity competes, directly or indirectly, with the business or activities of the Corporation or any subsidiary of the Corporation), for its own account, or in partnership or participation with, or as an employee, officer, director, stockholder, member, manager, trustee, general or limited partner, agent or representative of, any other Person, and no Permitted Person shall be required to devote its entire time (business or otherwise), or any particular portion of its time (business or otherwise) to the business of the Corporation or any subsidiary of the Corporation.

25

otherwise in competition with, the Corporation or any subsidiary of the Corporation and (iii) may do business with any client or customer of the Corporation or any subsidiary of the Corporation. Neither the Corporation nor any Stockholder nor any Director, nor any Affiliate of any of the foregoing, by virtue of this Agreement, shall have any rights in and to any such independent venture or the income or profits derived therefrom, regardless of whether or not such venture was initially presented to a Permitted Person as a direct or indirect result of its relationship with the Corporation. No Permitted Person shall have any obligation hereunder to present any business opportunity to the Corporation of which such Permitted Person becomes aware, even if the opportunity is one that the Corporation or any subsidiary of the Corporation might reasonably have pursued or had the ability or desire to pursue, in each case, if granted the opportunity to do so, and no Permitted Person shall be liable to the Corporation or any Stockholder (or any Affiliate thereof) for breach of any fiduciary or other duty relating to the Corporation (whether imposed by applicable law or otherwise), by reason of the fact that the Permitted Person pursues or acquires such business opportunity of which it becomes aware, directs such business opportunity to another Person or fails to present such business opportunity, or information regarding such business opportunity, to the Corporation or any subsidiary of the Corporation. Notwithstanding anything in thisSection 13(c), (i) the provisions ofSection 12(b) shall prohibit the use of Confidential Information in all such activities and (ii) a Permitted Person shall not take for itself a business opportunity of which such Permitted Person becomes aware solely because such business opportunity was presented by the Corporation or any subsidiary of the Corporation to such Permitted Person in such Permitted Person’s capacity as a member of the Board or as a Stockholder (whether via a formal meeting of the Board or Stockholders or materials and/or information otherwise provided to members of the Board or Stockholders) unless and until such time as the Corporation decides, by vote of the Board or the Stockholders, not to take such opportunity.

31

Stockholders with whom the Petitioner has its dispute (collectively, the “Respondent”) shall each select (and provide written notice thereof to the other) a qualifying arbitrator.

          (iv) The fees of the First and Second Arbitrators shall be borne by the Petitioner and Respondent, respectively. All other expenses of the arbitration shall be shared equally by the Petitioner and Respondent in accordance with the AAA Rules.

          (v) To the extent permissible under applicable law, the Corporation and the Stockholders agree that the award of the Arbitrators shall be final and shall not be subject to judicial review.

Nothing contained herein shall prevent the Corporation or a Stockholder from seeking preliminary injunctive relief in a court of competent jurisdiction.

     (h) Construction. The language used in this Agreement shall be deemed to be the language chosen by the parties to express their mutual intent, and no rule of strict construction will be applied against any party.

     (i) Severability.

In the case of any such invalidity or unenforceability, the parties hereto agree to use all commercially reasonable efforts to achieve the purpose of such provision by a new legally valid and enforceable stipulation.

     (j) Counterparts. This Agreement may be executed in multiple counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.

EXHIBIT C

Indemnification and Insurance

1.Definitions. Capitalized terms used but not otherwise defined in thisExhibit C shall have the meanings assigned to them in the Stockholders Agreement (the “Agreement”).

2.Rights to Indemnification.

     (a) To the full extent permitted by law, the Corporation shall indemnify and hold harmless its Directors, officers, Stockholders, the Affiliates of its Stockholders and the Representatives of each of the foregoing (collectively, the “Indemnitees”) from and against any and all claims, liabilities, damages, losses, costs and expenses (including amounts paid in satisfaction of judgments, compromises and settlements, as fines and penalties and legal or other costs and expenses of investigating or defending against any claim or alleged claim) of any nature whatsoever, known or unknown, liquidated or unliquidated, that are incurred by any Indemnitee and arise out of or in connection with the business of the Corporation or the performance by such Indemnitee of any of his or its responsibilities under Agreement, other than with respect to any actions or claims brought by or in the right of the Corporation or any of its subsidiaries. The rights created by thisExhibit C (but only with respect to actions, events and circumstances occurring during an Indemnitee’ s tenure as a Director or Stockholder or the tenure of the Director or Stockholder of which the Indemnitee is an Affiliate or Representative) shall continue as to an Indemnitee who (or the Director or Stockholder of which the Indemnitee is an Affiliate or Representative) has ceased to be a Director or Stockholder and shall inure to the benefit of such Indemnitee’ s heirs, executors, administrators, legal representatives, successors and assigns.

     (b) Without limiting any other provisions of the Agreement or thisExhibit C, the Corporation shall pay or reimburse, and indemnify and hold harmless each Indemnitee against, expenses reasonably incurred by such Person in connection with his appearances as a witness or other participation in a Proceeding involving or affecting the Corporation at a time when the Indemnitee is not a named defendant or respondent in the Proceeding. For the purposes of thisExhibit C, a “Proceeding” shall mean any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative, arbitrative or investigative, any appeal in such an action, suit or proceeding, and any inquiry or investigation that could lead to such an action, suit or proceeding.

     (c) Notwithstanding any other provision of the Agreement or thisExhibit C, any indemnification hereunder shall be provided out of and to the extent of Corporation assets only, and no Stockholder shall have personal liability on account thereof.

     (d) Notwithstanding any other provision of the Agreement or thisExhibit C, no indemnification shall be provided hereunder with respect to any actions or omissions of any Indemnitee that constitute criminal activity, willful misconduct, gross negligence, fraud, or a knowing violation or breach of the Agreement or thisExhibit C.

     (e) The indemnification provided in thisExhibit C is solely for the benefit of Indemnitees and shall not give rise to any right to indemnification in favor of any other persons.

3.Advance Payment of Expenses. Expenses incurred by an Indemnitee in defense or settlement of any claim that may be subject to a right of indemnification hereunder shall be advanced by the Corporation from time to time upon request prior to the final disposition thereof (an “Advancement of Expense”) upon receipt of a written agreement by the Indemnitee to repay such amount to the extent that it shall be determined ultimately that such Indemnitee is not entitled to be indemnified hereunder and the receipt by the Corporation of adequate security as determined by the Board.

4.Procedure for Indemnification.

     (a) Each Indemnitee shall give the Board notice in writing, as soon as practicable, of any matter or Proceeding for which such Indemnitee expects to or will seek indemnification under thisExhibit C. Such notice shall include a written request for indemnification, and shall be accompanied by any documentation and information as is reasonably available to Indemnitee and is reasonably necessary to determine whether and to what extent Indemnitee is entitled to indemnification. Indemnitee shall direct such notice, request and documentation to the Board at the address of the Corporation’s principal executive offices. Notwithstanding the foregoing, any failure of Indemnitee to provide such notice to the Board shall not relieve the Corporation of any liability that it may have to Indemnitee unless and to the extent such failure materially prejudices the interests of the Corporation.

     (b) With respect to any matter or Proceeding of which the Board is notified underSection 4(a), the Corporation shall be entitled to participate therein at its own expense and/or to assume the defense thereof at its own expense, with legal counsel approved by Indemnitee, which approval shall not be unreasonably withheld, upon the delivery to Indemnitee of written notice of its election to do so, in which case Indemnitee shall provide the Corporation such information and cooperation as the Corporation may reasonably require in connection with such defense and as shall be within Indemnitee’s power to so provide. After delivery of such notice from the Corporation to the Indemnitee of its intention to assume the defense of such matter or Proceeding, Indemnitee’ s approval of Corporation’s counsel, and the retention of such counsel, the Corporation will not be liable to Indemnitee under thisExhibit C for any fees and expenses of counsel subsequently incurred by Indemnitee with respect to such matter or Proceeding, other than as provided below. The Indemnitee shall have the right to employ his or its own counsel in connection with such matter or Proceeding, but the fees and expenses of such counsel incurred after such notice, approval and retention shall be at the expense of the Indemnitee, unless (i) the employment of counsel by the Indemnitee has been authorized by the Board, (ii) counsel to the Indemnitee shall have reasonably concluded that there may be a conflict of interest or position on any significant issue between the Corporation and the Indemnitee in the conduct of the defense of such action or (iii) the Corporation shall not in fact have employed counsel to assume the defense of such action, within the earlier of (A) twenty (20) calendar days and (B) the date upon which the Indemnitee must respond to the claim as to which indemnification is sought, in each of which cases the fees and expenses of counsel for the Indemnitee shall be at the expense of the Corporation, except as otherwise expressly provided by thisExhibit C. The Corporation shall not be entitled, without the consent of the Indemnitee, to assume the defense of any claim

2

brought by or in the right of the Corporation or as to which counsel for the Indemnitee shall have reasonably made the conclusion provided for in clause (ii) above. Notwithstanding any of the foregoing, the Corporation shall not be permitted to settle any matter or Proceeding, or any claim, issue or matter therein, on behalf of the Indemnitee, without the prior written consent of Indemnitee, unless (i) the Corporation assumes full and sole responsibility for such settlement and such settlement grants the Indemnitee a complete and unqualified release in respect of any potential or resulting liability or (ii) the Indemnitee is otherwise fully indemnified against all such liability and the Corporation shall not be liable for any amount paid by the Indemnitee in settlement of any Proceeding that is not defended by the Corporation, unless the Corporation has consented to such settlement, which consent shall not be unreasonably withheld.

5. Right of Indemnitee to Commence Proceeding.

     (a) If, following its receipt of the written notice described inSection 4(a) above, a majority of the Directors on the Board who are not at the time parties to, and who do not have any direct or indirect interest in, the relevant matter or Proceeding, determine that the Indemnitee has not met the applicable standard of conduct for which indemnification may be made as set forth in thisExhibit C or if a claim underSection 2 orSection 3 of thisExhibit C is not otherwise paid in full by the Corporation within thirty (30) days after such written claim has been received by the Corporation, except in the case of a claim for an Advancement of Expenses, in which case the applicable period shall be twenty (20) days. an Indemnitee may at any time thereafter commence a Proceeding against the Corporation to recover the unpaid amount of the claim. If successful in whole or in part in any such Proceeding, or in a Proceeding brought by the Corporation to recover any Advancement of Expenses, the Indemnitee shall also be entitled to be paid the expenses of prosecuting or defending such Proceeding.

     (b) In any Proceeding brought by an Indemnitee to enforce a right to Indemnification hereunder (but not in a Proceeding brought by Indemnitee to enforce a right to an Advancement of Expenses) it shall be a defense that (and in any Proceeding by the Corporation to recover an Advancement of Expenses, the Corporation shall be entitled to recover such expenses upon a final adjudication that) the Indemnitee has not met the requirements for indemnification hereunder;provided,however, that in any such Proceeding, neither (i) the failure of the Board to have made the determination prior to the commencement of such Proceeding that indemnification of Indemnitee is proper in the circumstances, (ii) an actual determination by the Board that Indemnitee has not met such applicable requirements, nor (iii) termination of any Proceeding by any judgment, order, settlement, or plea therein shall, of itself, create a presumption that Indemnitee has not met such applicable legal requirements or, in the case of such a Proceeding brought by Indemnitee, be a defense to such a Proceeding.

     (c) In any Proceeding brought by Indemnitee to enforce a right to indemnification or to an Advancement of Expenses hereunder, or by the Corporation to recover an Advancement of Expenses, the burden of proving that Indemnitee is not entitled to be indemnified, or to such Advancement of Expenses, under thisExhibit C or otherwise shall be on the Corporation.

     (d) Without limiting the foregoing, any action commenced pursuant to thisSection 5shall be conducted in all respects as ade novoadjudication on the merits;provided,however, that if a final unappealable determination shall have been made pursuant to the foregoing

3

Sections 5(a),5(b) and5(c) that an Indemnitee is entitled to indemnification, the Corporation shall be bound thereby. The Corporation and all Indemnitees shall be precluded from asserting in any action pursuant to thisSection 5(d) that the procedures and presumptions of thisExhibit C are not valid, binding and enforceable.

6.Non-Exclusivity of Rights. The rights to indemnification and to the Advancement of Expenses conferred in thisExhibit C shall not be exclusive of any other right which any Person may have or hereafter acquire under applicable law, under any other agreement, pursuant to any vote of the Board or otherwise; provided, that the Indemnitee shall not be entitled to recover more than once for the same damage. By thisExhibit C, the Corporation intends to indemnify the Indemnitees to the fullest extent permitted by law, notwithstanding that such indemnification is not specifically authorized by the other provisions of thisExhibit C, the Agreement or by statute. In the event of any change, after the date of the Agreement, in any applicable law, statute, or rule which expands the right of the Corporation to indemnify the Indemnitees, such changes shall be, ipso facto, within the purview of the Indemnitees’ rights and the Corporation’s obligations under thisExhibit C. In the event of any change in any applicable law, statute or rule which narrows the right of the Corporation to indemnify the Indemnitees, such changes, to the extent not otherwise required by such law, statute or rule to be applied to thisExhibit C shall have no effect on thisExhibit C or the Agreement or the parties’ rights and obligations hereunder.

7.Repeal or Modification. Any repeal or modification of thisExhibit C shall only be prospective and shall not affect the rights under thisExhibit C in effect at the time of the alleged occurrence of any action or omission to act giving rise to liability.

8.Insurance. The Corporation shall maintain a directors’ and officers’ insurance policy in the face amount of at least $5,000,000 with responsible carriers, at the Corporation’s expense, and shall be authorized to maintain such additional insurance as the Board may determine necessary or appropriate to insure any amounts indemnifiable hereunder as well as to protect the Indemnitees or any employee or agent of the Corporation or another enterprise against any expense, liability or loss of the kind referred to in thisExhibit C, whether or not the Corporation would have the power to indemnify such Indemnitees against such expense, liability or loss under the applicable law. If, at the time of the receipt by the Board of a notice of a matter or Proceeding for which indemnification is sought pursuant toSection 4 above, the Corporation has director and officer liability insurance in effect, the Corporation shall give prompt notice of the commencement, or the threat of the commencement, of such matter or Proceeding to the insurers in accordance with the procedures set forth in the respective applicable insurance policies. The Corporation shall thereafter take all necessary action to cause such insurers to pay, on behalf of the Indemnitee, all amounts payable as a result of such matter or Proceeding in accordance with the terms of such policies; provided, that no such payments by such insurers shall relieve the Corporation of any liability or obligation which it may have to the Indemnitee except as and to the extent expressly provided under thisExhibit C.

9.Contribution by the Corporation. The Corporation hereby agrees that, in the event that the indemnification provided for in thisExhibit C is for any reason finally judicially determined to be unavailable (other than any determination that the Indemnitee is not entitled to indemnification pursuant toSection 2(d)), the Corporation shall contribute to the payment of any

4

and all expenses, liability and loss (including attorneys’ fees, judgments, fines, or other excise taxes or penalties (including those under the U.S. Employee Retirement Income Security Act of 1974, as amended), and amounts paid in settlement) in such proportion as is appropriate to reflect the relative fault of the Corporation and the Indemnitee with respect to such expenses, liability and loss.

10.Miscellaneous.

     (a) Provisions from the Agreement. For the sake of clarity,Sections17(e),17(f),17(g) and17(j) of the Agreement shall apply to thisExhibit C as if set forth herein in full.

     (b) No Third Party Beneficiaries. Nothing in thisExhibit C, 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; provided, that the Indemnitees are intended third party beneficiaries of thisExhibit C.
