        WHEREAS, simultaneously with the execution and delivery of this Agreement by the parties hereto, the Company and each of the Investors entered into a Securities Purchase Agreement (as may be amended from time to time, the "Purchase Agreement") pursuant to which, among other things, the Company has agreed to issue to the Investors and/or Affiliates thereof (a) the Notes (as defined in the Purchase Agreement), which Notes may be converted into shares of common stock, par value $0.001 per share ("Common Stock"), of the Company, (b) the Apollo Warrants (as defined in the Purchase Agreement), (c) the Apollo Preferred Shares (as defined in the Purchase Agreement), and (d) under certain circumstances, shares of Common Stock (the shares of Common Stock, the Notes, the shares of Common Stock into which such Notes are convertible into and for which such Apollo Warrants are exercisable and the Apollo Preferred Shares, are collectively referred to herein as the "Securities") and (d) certain royalty interests in the Company; and

        WHEREAS, each of the parties hereto wishes to set forth in this Agreement certain terms and conditions regarding the Investors' ownership of the Securities; and

        WHEREAS, this Agreement (a) shall become effective as of the Closing (as defined in the Purchase Agreement) or (b) shall automatically terminate (and be of no further force and effect) if the Purchase Agreement is terminated prior to the Closing.

        NOW, THEREFORE, in consideration of the mutual covenants, representations, warranties and agreements contained in this Agreement, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound hereby, the parties agree as follows:

ARTICLE I

GOVERNANCE

        1.1    Composition of the Board of Directors.    

        (a)   Following the Closing and until the Charter Designation Termination Date, the Company shall take all actions necessary to preserve, and ensure the continuation of, the rights of the Preferred Share Purchaser (or, in the event the Preferred Share Purchaser has transferred any Apollo Preferred Shares to any of its Affiliates, the rights of the Majority Holders) to elect directors to the Company's board of directors (the "Board") pursuant to and in accordance with the articles of incorporation of the Company (as amended by the Certificate of Designation (as defined in the Purchase Agreement)) (the "Charter Designation Rights"), including, without limitation, by nominating for election (with respect to the Charter Designations Rights) the Persons proposed by the Preferred Share Purchaser (or, in the event the Preferred Share Purchaser has transferred all of the Apollo Preferred Shares to any of its Affiliates, the Majority Holders) pursuant to Section 1.1(c) below or otherwise.

        (b)   From and after the Charter Designation Termination Date and until an Investor Rights Termination Event, the Preferred Share Purchaser (or an Affiliate thereof designated by the Preferred Share Purchaser) shall have the right to appoint one observer on the Board (the "Board Observer") so long as it and/or its Affiliates hold any Securities (it being understood that a Board Observer shall have all the rights (other than voting rights) of a director on the Board, including (i) the right to attend all meetings of the Board as an observer, (ii) the right to receive advance notice of each meeting, including such meeting's time and place, at the same time and in the same manner as such notice is

provided to the members of the Board, (iii) the right to receive copies of all materials, including notices, minutes, consents and regularly compiled financial and operating data distributed to the members of the Board at the same time as such materials are distributed to the Board, and to access the same information concerning the business and operations of the Company, and (iv) the right to discuss the affairs, finances and accounts of the Company with, and to make proposals and furnish advice with respect thereto, to the Board without voting).

        (c)   The Preferred Share Purchaser (or, in the event the Preferred Share Purchaser has transferred all of the Apollo Preferred Shares to any of its Affiliates, the Majority Holders) shall notify the Company of the identity of the proposed Investor Directors, in writing, no later than reasonably promptly after such information is reasonably requested by the Board or any committee thereof responsible for the nomination of directors for inclusion in (x) a proxy or information statement for a meeting of shareholders (or action by written consent) or (y) any other documents or reports to be filed by the Company with the SEC, together with all information about the proposed Investors Directors as shall be reasonably requested by the Board or any committee thereof responsible for the nomination of directors; provided, however, that in no event shall the Company require more information from the Preferred Share Purchaser or the Majority Holders regarding the proposed Investor Directors than is required for any other person nominated for election to the Board; provided, further, that in the event the Preferred Share Purchaser or the Majority Holders, as applicable, fails to provide any such notice, the persons then serving as the Investor Directors shall be deemed to be the proposed Investor Directors nominated for election for such meeting or written consent for purposes of this Section 1.2(c).

        (d)   Upon the request of the Preferred Share Purchaser, the Company shall cause one or more Investor Directors elected or serving in connection with the Charter Designation Rights to be appointed or elected to the boards of directors (or similar governing bodies) of any or all of the other Group Companies, such that the Investor Directors' representation on such boards will be proportionate to the Investor Directors' representation on the Board at such time.

        (e)   The provisions of the Certificate of Designation and this Article I are intended to provide the Preferred Share Purchaser and its Affiliates with the minimum Board representation rights set forth herein. Nothing in the Certificate of Designation or this Agreement shall prevent the Company from having a greater number of nominees or designees of the Preferred Share Purchaser and its Affiliates on the Board than otherwise provided herein.

        (f)    If the Company at any time after the Closing becomes eligible for the "controlled company" exception under the rules of the Principal Market as a result of the Investor Percentage Interest exceeding fifty percent (50%), the Company shall, upon the request of the Preferred Share Purchaser, take any and all action necessary to qualify the Company for such exception.

        (g)   If, after the date hereof, there is a change in applicable Law or the rules of the Principal Market that prohibits the Charter Designation Rights, then the Company shall use reasonable best efforts to remove such prohibitions and, if it is unsuccessful in doing so, the Company and the Preferred Share Purchaser will discuss in good faith amendments to the terms of the Certificate of Designation to remove such prohibition (it being acknowledged that in no event will the Preferred Share Purchaser be obligated to accept a lesser number of directors than a number equal to the Investor Percentage Interest multiplied by the outstanding number of directors on the Board).

        1.2    Committees.    From and after the Closing and until such time as the Preferred Share Purchaser (or the Majority Holders, as applicable) is no longer entitled to elect at least two members of the Board pursuant to the Charter Designation Rights, the Preferred Share Purchaser (or the Majority Holders, as applicable) shall be entitled to designate and appoint (and the Company shall cause such appointment (and the other appointments referred to in this Section 1.2) to occur and become effective) Investor Directors to serve on all of the committees of the Board in proportion to

3

the Investor Directors' overall representation on the Board (rounded up or down to the nearest whole number); provided that the Preferred Share Purchaser (or the Majority Holders, as applicable) shall be entitled to designate and appoint at least one member to each committee so long as it is entitled to elect at least one member to the Board. In the event that an insufficient number of Investor Directors meet the eligibility requirements mandated by applicable Law or applicable national securities exchange rules (in either case from which the Company is not then exempt, by reason of operating under an applicable controlled company exemption or otherwise), the Preferred Share Purchaser (or the Majority Holders, as applicable) shall be entitled to designate and appoint a number of Investor Directors to such committee in a non-voting observer capacity as it would have been able to designate as full members in the absence of such ineligibility. Each such observer shall have the same rights as a director (other than voting rights), including the right to participate in all deliberations of each committee. Observers shall not be counted towards a quorum. The Company shall send to each such observer the notice of the time and place of such meeting in the same manner and at the same time as it shall send such notice to the committee members. The Company shall also provide to each such observer copies of all notices, reports, minutes and consents at the time and in the manner as they are provided to the committee members.

        1.3    Consent Rights.    From and after the Closing, the Company shall not, and shall cause each of its subsidiaries to not (the Company and its current and future subsidiaries together, the "Group Companies"), take, enter into or effectuate any of the following actions or transactions without the prior written approval of the Preferred Share Purchaser (provided that (x) the consent rights set forth below shall not be applicable for so long as the Investor Percentage Interest is less than the Initial Threshold, and (y) the consent rights set forth below (except for the consent rights set forth in subsections (a), (c), (d), (e), (f), (o), (p), (q), (r) (solely with respect to the Chief Executive Officer), (s) and (t) (solely with reference to the foregoing subsections)) shall terminate upon the Conversion Milestone):

        (a)   (i) any increase or decrease in the number of directors serving on the Board (or similar governing body) or any committee thereof, except as permitted by the terms of the Certificate of Designation, or (ii) any alteration of the powers of the Board (or similar governing body) or any committee thereof (including creating any new committee), except for any alterations of a non-material, routine or administrative nature which do not adversely affect the rights of the Investors Group;

        (d)   making any material change in the nature of its business or in its lines of business;

ARTICLE II

OTHER COVENANTS

        2.1    Preemptive Rights.    

        (a)   Each Royalty Purchaser will have the preemptive rights set forth in this Section 2.1 with respect to any issuance of any Common Stock or Equity-based Securities by any Group Company that are issued after the Closing (any such issuance other than those described in clauses (i) through (iii) below, a "Preemptive Rights Issuance"), except for (i) issuances to employees, directors and consultants pursuant to and in accordance with stock incentive plans of the Company that were publicly filed with the Commission prior to the date hereof (provided that any such issuances are made in accordance with the terms, conditions and limitations of such plans as they existed as of the date of hereof and without effect to any amendments or other modifications thereof after the date hereof unless approved by the Investors Group) or written agreements set forth on Schedule 9.13 of the Purchase Agreement (provided that any such issuances are made in accordance with the terms, conditions and limitations of such agreements as they existed as of the date hereof and without effect to any amendments or other modifications thereof after the date hereof unless approved by the Investors Group), (ii) issuances of shares of Common Stock as consideration in any merger approved by pursuant to Section 1.3(o), or (iii) issuances of shares of Common Stock pursuant to and in accordance with warrant agreements entered into (and publicly filed with the Commission) prior to the date of the Purchase Agreement and previously disclosed to the Investors Group (provided that any such issuances are made in accordance with the terms, conditions and limitations of such warrant agreements as they existed as of the date of the Purchase Agreement and without effect to any amendments or other modifications thereof after the date of the Purchase Agreement unless approved by the Investors Group). The preemptive rights in this Section 2.1 shall terminate at such time as the Investor Percentage Interest falls below ten percent (10%).

        (b)   If any Group Company at any time or from time to time effects a Preemptive Rights Issuance, such Group Company shall give written notice to each Royalty Purchaser a reasonable period in

7

---

advance of such issuance (but in no event later than ten (10) days prior to such issuance), which notice shall set forth the number and type of the securities to be issued, the issuance date, the offerees or transferees, the price per security, and all of the other terms and conditions of such issuance, which shall be deemed updated by delivery of the final documentation for such issuance to each Royalty Purchaser. Each Royalty Purchaser may, by written notice to such Group Company (a "Preemptive Rights Notice") delivered no later than twenty-one (21) days after the consummation of such Preemptive Rights Issuance, elect to purchase (or designate an Affiliate thereof (including, without limitation, another Investor) to purchase) a number of securities specified in such Preemptive Rights Notice (which number may be any number up to but not exceeding such Royalty Purchaser's pro rata portion of the Preemptive Rights Cap Amount applicable to such Preemptive Rights Issuance), on the same terms and conditions as such Preemptive Rights Issuance (it being understood and agreed that (i) the price per security that the Investors shall pay shall be the same as the price per security set forth in the Preemptive Rights Notice, and (ii) the Investors shall not be required to comply with any terms, conditions, obligations or restrictions (including, without limitation, any non-compete, standstill or other limitations but excluding any remaining period of a transfer or lock-up restriction applicable at such time to other purchasers in such Preemptive Rights Issuance) not directly necessary for the effectuation of the sale or issuance of such securities). If the Royalty Purchasers exercise their preemptive rights hereunder with respect to such Preemptive Rights Issuance, the Company shall (or shall cause such subsidiary to) issue to the Royalty Purchasers (or their designated Affiliates) the number of securities specified in such Preemptive Rights Notice as soon as reasonably practicable thereafter. For the avoidance of doubt, in the event that the issuance of Common Stock or Equity-based Securities in a Preemptive Rights Issuance involves the purchase of a package of securities that includes Common Stock or Equity-based Securities and other securities in the same Preemptive Rights Issuance, each Royalty Purchaser shall have the right to acquire its applicable pro rata portion of such other securities, together with its applicable pro rata portion of such Common Stock or Equity-based Securities, in the same manner described above (as to amount, price and other terms).

        (c)   The election by any Royalty Purchaser not to exercise its preemptive rights hereunder in any one instance shall not affect its right (other than in respect of a reduction in the Investors Rights Percentage) as to any future Preemptive Rights Issuances. Each Royalty Purchaser shall be entitled to deliver its own notices and make its own elections for purposes of this Section 2.1, and the non-exercise by any Royalty Purchaser shall not affect the rights of any other Investor under this Section 2.1.

        (d)   For the avoidance of doubt, the Royalty Purchasers shall not have any preemptive rights under this Section 2.1 with respect to any issuance of any Common Stock or Equity-based Securities by any Group Company occurring at or prior to the Closing (a "Pre-Closing Issuance"). Each Investor's preemptive rights (if any) with respect to Pre-Closing Issuances shall be limited to their rights under Section 9.13 of the Purchase Agreement.

        2.2    Information Rights.    

        (a)   From the Closing until the Investor Percentage Interest is less than five percent (5%), the Company will prepare and furnish the following to each Investor (and in the case of clause (iv), make available to each Investor):

        (i)    As soon as available, and in any event within ninety (90) days after the end of each fiscal year of the Group Companies, a copy of the audited consolidated balance sheet of the Group Companies as at the end of each such fiscal year and the related audited consolidated statements of income, cash flows and changes in shareholders equity for such year of the Group Companies setting forth, in each case in comparative form the figures for the previous fiscal year, or, in the case of such balance sheet, for the last day of such fiscal year, all in reasonable detail.

        (iv)  As soon as reasonably practicable after a request by any Investor to inspect, review or consult with (as applicable), all books and records and facilities and properties and management (including project managers and other key employees) of each Group Company at reasonable times and intervals.

        (v)   As soon as reasonably practicable, any other information reasonably requested by such Investor; provided that there is a tax, accounting, investment monitoring or other valid purpose for requesting such information.

REGISTRATION

        (a)    Requests for Registration.    Subject to Section 4.1(b), at any time after the Closing, the Investors Group may request in writing and require that the Company effect the registration (which, for avoidance of doubt, may be a Shelf Registration) of all or any part of the Registrable Securities held by any Investor (a "Registration Request") (which Registration Request shall specify the number of Registrable Securities intended to be registered and the intended method of distribution). Promptly after its receipt of any Registration Request, the Company will use its best efforts to register, as soon as practicable in accordance with the provisions of this Agreement, all Registrable Securities that have been requested to be registered in the Registration Request.

outstanding) and (y) the close of business on the one hundred and eightieth (180^th) day after such registration has been declared or ordered effective by the Commission.

        (ii)   The Company also shall not be required to effect any Demand Registration if the Company has notified the Investors Group that, in the good faith judgment of the Company, due to a pending material transaction or material event (other than the Demand Registration that is the subject of such Registration Request) it would be materially detrimental to the Company for such registration to be effected at such time, in which event the Company shall have the right to defer such filing for a period of not more than thirty (30) days after receipt of the request of the Investors Group; provided that such right to delay a request shall be exercised by the Company not more than three (3) times in any twelve (12)-month period and not more than once in any four (4)-month period. If the Company postpones the filing of a prospectus or the effectiveness of a Registration Statement pursuant to this Section 4.1(b)(ii) , the Investors Group will be entitled to withdraw its Registration Request and, if such request is withdrawn, such registration request will not count for the purposes of the limitation set forth in this Section 4.1(b).

        (c)    Selection of Underwriters.    If any Demand Registration (or any Underwritten Shelf Takedown) is proposed to be underwritten, the lead underwriter (and all of the other underwriters, other than the second bookrunner) to administer the offering in connection with any such Demand Registration or Underwritten Shelf Takedown will be chosen by the Investors Group subject to prior consultation with the Company. The Company shall be entitled to designate a second bookrunner in any offering in connection with any such Demand Registration or Underwritten Shelf Takedown. In connection with any registered offering of the Company in which none of the Investors Group is offering any securities, so long as the Investor Percentage Interest is twenty percent (20%) or more at such time, the underwriters for such offering shall be selected by the mutual agreement of the Company and the Investors Group, each acting reasonably.

        (d)    Priority on Demand Registrations.    The Company will not include in any Demand Registration pursuant to this Section 4.1 (or any Shelf Takedown, whether an Underwritten Shelf Takedown or otherwise) any shares of Common Stock (or other securities) that are not Registrable Securities, without the prior written consent of the Investors Group. If the lead underwriter in a Demand Registration that is an underwritten offering advises the Company that in its reasonable opinion the number of Registrable Securities (and, if permitted hereunder, other shares of Common Stock requested to be included in such offering) exceeds the number of securities that can be sold in such offering without adversely affecting the marketability of the offering (including an adverse effect on the per share offering price), the Company will include in such offering only such number of securities that, in the reasonable opinion of such underwriter, can be sold without adversely affecting the marketability of the offering (including an adverse effect on the per share offering price), which securities will be so included in the following order of priority: (i) first, Registrable Securities of the Investors Group, (ii) second, if there is any additional availability after full satisfaction of clause (i) above, any shares of Common Stock to be sold by the Company, and (iii) third, if there is any additional availability after full satisfaction of clauses (i) and (ii) above, any shares of Common Stock requested to be included pursuant to the exercise of other contractual piggyback registration rights granted by the Company pro rata among such persons (if applicable) on the basis of the aggregate number of securities requested to be included by such persons.

        4.2    Piggyback Registrations.    

        (a)    Right to Piggyback.    Whenever the Company proposes to register any shares of Common Stock (or securities convertible into or exercisable for shares of Common Stock) in connection with a Public Offering solely for cash (whether for its own account (a "Company Registration") or for the account of any other Person (other than the Investors Group) possessing contractual demand registration rights (a "Shareholder Registration")), other than pursuant to a Demand Registration or a

11

---

Special Registration, and the registration form to be filed may be used for the registration or qualification for distribution of Registrable Securities, the Company will give prompt written notice to the Investors Group of its intention to effect such a registration and, subject to Section 4.2(c), will include in such registration all Registrable Securities with respect to which the Company has received written requests for inclusion therein within fifteen (15) Business Days after the date of the Company's notice (a "Piggyback Registration") (it being understood and agreed that, for the avoidance of doubt, the Investors Group's election to include its Registrable Securities in such registration and/or sell its Registrable Securities in such related offering may be conditioned on the pricing achieved in the contemplated registration or offering). Subject to the foregoing, the Investors Group may withdraw its Registrable Securities from such Piggyback Registration by giving written notice to the Company and the managing underwriter, if any, on or before the fifth (5th) Business Day prior to the planned effective date of such Piggyback Registration. The Company may terminate or withdraw any registration under this Section 4.2 prior to the effectiveness of such registration, whether or not the Investors Group has elected to include Registrable Securities in such registration, and except for the obligation to pay Registration Expenses pursuant to Section 4.5, the Company will have no liability to the Investors Group in connection with such termination or withdrawal.

        (b)    Underwritten Registration.    If the registration referred to in Section 4.2(a) is proposed to be underwritten, the Company will so advise the Investors Group. In such event, the right of the Investors Group to registration pursuant to this Section 4.2 will be conditioned upon the Investors Group's participation in such underwriting and the inclusion of the Investors Group's Registrable Securities in the underwriting, and the Investors Group will (together with the Company and the other securityholders distributing their securities through such underwriting) enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting in accordance with Section 4.1(c).

        (c)    Priority on Registrations.    

        (i)    If a Piggyback Registration relates to an underwritten primary offering for a Company Registration, and the lead underwriter advises the Company that in its reasonable opinion the number of securities requested to be included in such registration exceeds the number that can be sold without adversely affecting the marketability of such offering (including an adverse effect on the per share offering price), the Company will include in such registration or prospectus only such number of securities that in the reasonable opinion of such underwriter can be sold without adversely affecting the marketability of the offering (including an adverse effect on the per share offering price), which securities will be so included in the following order of priority: (i) first, the shares of Common Stock the Company proposes to sell, and (ii) second, if there is any additional availability after full satisfaction of clause (i) above, shares of Common Stock (including Registrable Securities) of any investors (including the Investors Group) who have requested registration of their securities pursuant to contractual piggyback registration rights (including pursuant to Section 4.2(a)), pro rata on the basis of the aggregate number of such securities or shares owned by each such investor.

        (ii)   If a Piggyback Registration relates to an underwritten offering for a Shareholder Registration, and the lead underwriter advises the Company that in its reasonable opinion the number of securities requested to be included in such registration exceeds the number that can be sold without adversely affecting the marketability of such offering (including an adverse effect on the per share offering price), the Company will include in such registration or prospectus only such number of securities that in the reasonable opinion of such underwriter can be sold without adversely affecting the marketability of the offering (including an adverse effect on the per share offering price), which securities will be so included in the following order of priority: (i) first, the shares of Common Stock to be included by the investor that exercised its demand rights with respect to the Shareholder Registration, and (ii) second, if there is any additional availability after full satisfaction of clause (i) above, shares of Common Stock (including Registrable Securities) of any other investors (including the Investors Group) who have

12

---

requested registration of their securities pursuant to contractual piggyback registration rights (including pursuant to Section 4.2(a)), pro rata on the basis of the aggregate number of such securities or shares owned by each such investor.

        4.3    Shelf Registration Statement.    

        (a)   Not later than the earlier of thirty (30) days after (or, if the Company is not then S-3 eligible, sixty (60) days after) (x) Project Completion (as defined in the Purchase Agreement) or (y) a written request by the Investors Group, the Company shall file with the Commission either (i) a Shelf Registration Statement or (ii) pursuant to Rule 424(b) under the Securities Act, a prospectus supplement that shall be deemed to be part of an existing Shelf Registration Statement in accordance with Rule 430B under the Securities Act, in each case relating to the offer and sale of all of the Registrable Securities (the "Shelf Registration"). The Company shall, if such Shelf Registration Statement is not automatically effective, use its best efforts to cause such Shelf Registration Statement to be declared effective under the Securities Act as soon as possible after filing. The Company shall amend or supplement such Shelf Registration Statement to include additional Registrable Securities. The Company shall use its best efforts to cause the Shelf Registration Statement to remain effective, including by filing a replacement Shelf Registration Statement upon the expiration of the original Shelf Registration Statement until such time as there are no remaining Registrable Securities, and amend the Shelf Registration Statement from time to time as requested by the Investors Group to permit disposition of Registrable Securities pursuant thereto in accordance with the preferred method of distribution of Securities under the Shelf Registration Statement of the Investors Group.

        (b)   The Investors Group shall be entitled, at any time and from time to time when a Shelf Registration Statement is effective, to sell such Registrable Securities as are then registered pursuant to such Shelf Registration Statement, in any manner as provided in its notice to the Company (including in any underwritten offering, if so requested) (each such sale, a "Shelf Takedown"); provided, that, (i) if such Shelf Takedown is to be underwritten (an "Underwritten Shelf Takedown"), the Investors Group shall provide the Company at least thirteen (13) Business Days' written notice prior to the expected closing of such Underwritten Shelf Takedown (it being understood and agreed that, notwithstanding anything to the contrary herein, there shall be no aggregate limit to the number of Underwritten Shelf Takedowns that may be required to be consummated hereunder (except that the parties hereto agree that no more than three (3) Underwritten Shelf Takedowns may be required to be consummated hereunder in any twelve (12)-month period)) and (ii) if such takedown does not involve an Underwritten Shelf Takedown (a "Non-Underwritten Shelf Takedown"), the Investors Group shall provide the Company at least five (5) Business Days' written notice prior to the expected closing of such Non-Underwritten Shelf Takedown (it being understood and agreed that, notwithstanding anything to the contrary herein, there shall be no limit to the number of Non-Underwritten Shelf Takedowns that may be required to be consummated hereunder). The Investors Group shall give the Company prompt written notice after the consummation of each Shelf Takedown.

        4.4    Registration Procedures.    Subject to Section 4.1(b), whenever the Investors Group has requested that any Registrable Securities be registered pursuant to Section 4.1 or 4.2 of this Agreement (including with respect to a Shelf Registration and any Underwritten Shelf Takedowns or Non-Underwritten Shelf Takedowns), the Company will use its best efforts to effect the registration and sale of such Registrable Securities as soon as reasonably practicable in accordance with the intended method of disposition thereof, and pursuant thereto the Company shall use its best efforts to as expeditiously as reasonably practicable:

        (a)   With respect to a Demand Registration or a Piggyback Registration, prepare and file with the Commission a registration statement with respect to such Registrable Securities (which, for the avoidance of doubt, may be a Shelf Registration and any Underwritten Shelf Takedowns or Non-Underwritten Shelf Takedowns) and use its best efforts to cause such registration statement to

become effective, or prepare and file with the Commission a prospectus supplement with respect to such Registrable Securities pursuant to an effective registration statement and, upon the request of the Investors Group, keep such registration statement effective or such prospectus supplement current, until (i) in the case of a Shelf Registration, the date on which all Registrable Securities covered thereby have been sold pursuant to such registration (or if earlier, the first date on which no Registrable Securities remain outstanding) and (ii) in the case of any registration statement not related to a Shelf Registration, the earlier of (A) the date on which all Registrable Securities covered thereby have been sold pursuant to such registration (or if earlier, the first date on which no Registrable Securities remain outstanding) and (B) the close of business on the one hundred and eightieth (180th) day after such registration has been declared or ordered effective by the Commission;

        (b)   Prepare and file with the Commission such amendments and supplements to the applicable registration statement and the prospectus or prospectus supplement used in connection with such registration statement as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement for the period set forth in paragraph (a);

        (e)   Enter into customary agreements (including, if the method of distribution is by means of an underwriting, an underwriting agreement in customary form with the managing underwriter(s) of such offering) and take such other actions (including participating in and making documents available for the due diligence review of underwriters if the method of distribution is by means of an underwriting) as are reasonably required in order to facilitate the disposition of such Registrable Securities;

        (f)    With respect to a Demand Registration (including any Shelf Takedowns), at the request of the Investors Group, cause its senior executives to participate, at the Company's expense, in customary investor presentations and "road shows" (to be scheduled in a collaborative manner so as not to unreasonably interfere with the conduct of the business of the Company);

        (g)   Notify the Investors Group at any time when a prospectus relating thereto is required to be delivered under the Securities Act of the happening of any event as a result of which the applicable prospectus, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing;

        (h)   Make such representations and warranties to the Investors Group of the Registrable Securities covered by the applicable registration statement and the underwriters, if any, in form, substance and scope as are customarily made by issuers to underwriters in an underwritten Public

        (k)   Use its best efforts to prevent the issuance or obtain the withdrawal of any order suspending the effectiveness of any registration statement referred to in Section 4.4(j)(iii) at the earliest practicable time;

        (l)    Upon the occurrence of any event contemplated by Section 4.4(j)(v) above, promptly (and in any event within five (5) Business Days) prepare a post-effective amendment to such registration statement or a supplement to the related prospectus or file any other required document so that, as thereafter delivered to the Investors Group, the prospectus will not contain an untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. If the Company notifies the Investors Group in accordance with Section 4.4(j)(v) above to suspend the use of the prospectus until the requisite changes to the prospectus have been made, then the Investors Group shall suspend use of such prospectus and use its commercially reasonable efforts to return to the Company all hard copies of such prospectus (at the Company's expense) other than permanent file copies then in the Investors Group's possession, and the period of effectiveness of such registration statement provided for above shall be extended by the number of days from and including the date of the giving of such notice to the date Investors Group shall have received such amended or supplemented prospectus pursuant to this Section 4.4(l);

        (m)  Use its best efforts to procure the cooperation of the Company's transfer agent in settling any offering or sale of Registrable Securities, including with respect to the transfer of physical stock certificates into book-entry form in accordance with any procedures reasonably requested by the Investors Group or the underwriters;

        (n)   If requested by the managing underwriter or the Investors Group, promptly incorporate in a supplement or post-effective amendment such information as the managing underwriter and the Investors Group agree should be included therein relating to the sale of the Registrable Securities, including, without limitation, information with respect to the number of shares of Registrable Securities being sold to underwriters, the purchase price being paid therefor by such underwriters and with respect to any other terms of the underwritten offering of the Registrable Securities to be sold in such underwritten offering, and make all required filings of such supplement or post-effective amendment as soon as notified of the matters to be incorporated in such supplement or post-effective amendment;

        (o)   Cooperate with the Investors Group and the managing underwriter, if any, to facilitate the timely preparation and delivery of certificates not bearing any restrictive legends representing the Registrable Securities to be sold, and cause such Registrable Securities to be in such denominations and registered in such names as the managing underwriter may reasonably request at least three (3) Business Days prior to any sale of Registrable Securities to the underwriters;

        (r)   Otherwise use its best efforts to comply with all applicable rules and regulations of the Commission, and make generally available to the Company's securityholders an earnings statement satisfying the provisions of Section 11(a) of the Securities Act, (A) covering the twelve (12)-month period commencing at the end of the fiscal quarter in which the applicable registration statement becomes effective, within forty-five (45) days of the end of such twelve (12)-month period, and (B) beginning with the first month of the Company's first fiscal quarter commencing after the effective date of the applicable registration statement, which statements shall cover such twelve (12)-month period.

        4.7    Rules 144 and 144A and Regulation S.    The Company covenants that it will file any and all reports required to be filed by it under the Securities Act and the Exchange Act (or, if the Company is not required to file such reports, it will make publicly available such necessary information for so long as necessary to permit sales pursuant to Rule 144, Rule 144A or Regulation S under the Securities Act) and that it will take such further action as the Investors Group may reasonably request, all to the extent required from time to time to enable the Investors Group to sell its Securities (including, without limitation, its Notes and its Registrable Securities) without registration under the Securities Act within the limitation of the exemptions provided by Rule 144, Rule 144A or Regulation S under the Securities Act, as such Rules may be amended from time to time, or any similar rule or regulation hereafter adopted by the Commission.

ARTICLE V

INDEMNIFICATION

        5.1    Indemnification.    

        (a)   The Company agrees to indemnify and hold harmless the Investors, their respective officers, directors, managers, employees, fiduciaries and general and limited partners and each Person who is a controlling Person of any of the Investors within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (and the officers, directors, managers, employees, fiduciaries and general and limited partners thereof) (each such person being referred to herein as a "Covered Person") against, and pay and reimburse such Covered Persons for, any losses, claims, damages or liabilities, joint or several, to which such Covered Person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon (i) any untrue or alleged untrue statement of material fact contained or incorporated by reference in any Registration Statement, prospectus or preliminary prospectus used to register Registrable Securities pursuant to this Agreement or any amendment thereof or supplement thereto, or any document incorporated by reference therein, (ii) any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading and (iii) any violation by the Company of any federal, state or common law rule, regulation or law applicable to the Company and relating to action required of or inaction by the Company in connection with any registration or offering of Registrable Securities, and the Company will pay and reimburse such Covered Persons for any legal or any other expenses actually and reasonably incurred by them in connection with investigating, defending or settling any such loss, claim, damage, liability, action or proceeding; provided that the Company shall not be liable to a Covered Person in any such case to the extent that any such loss, claim, damage, liability (or action or proceeding in respect thereof) or expense arises out of or is based upon an untrue statement or alleged untrue statement, or omission or alleged omission, made or incorporated by reference in such Registration Statement, any such prospectus or preliminary prospectus or any amendment or supplement thereto, or any document incorporated by reference therein, in reliance upon, and in conformity with, written information prepared and furnished to the Company by such Covered Person expressly for use therein, or arises out of or is based on the failure of the Investors Group to deliver a copy of the Registration Statement or prospectus or any amendments or supplements thereto after the Company has furnished the Investors Group with copies thereof.

        (b)   In connection with any Registration Statement in which any Investor is participating, the Investor shall furnish to the Company in writing such information as the Company reasonably requests for use in connection with any such Registration Statement or prospectus and shall indemnify and hold harmless the Company, its directors and officers and any Person who is or might be deemed to be a controlling person of the Company or any of its subsidiaries within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act against any losses, claims, damages, liabilities, joint or several, to which the Company or any such director, officer, or controlling person may become subject under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon (i) any untrue or alleged untrue statement of material fact contained in the Registration Statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or (ii) 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 (x) that such untrue statement or omission is made in such Registration Statement, any such prospectus or preliminary prospectus or any amendment or supplement thereto in reliance upon and in conformity with written information prepared and furnished to the Company by the Investor expressly for use therein and (y) such statement or omission was not corrected in a subsequent writing prior to or concurrently with the sale of the securities to the Person asserting such loss, and the Investor will reimburse the Company and each such director, officer

and controlling Person for any legal or any other expenses actually and reasonably incurred by them in connection with investigating, defending or settling any such loss, claim, damage, liability, action or proceeding; provided that the obligation to indemnify and hold harmless and reimburse shall be individual and several to each Investor and shall be limited to the net proceeds received by such Investor from the sale of its Registrable Securities pursuant to the offering which gives rise to the right to so indemnify, hold harmless and reimburse (less the aggregate amount of any damages that the Investor has otherwise been required to pay in respect of such loss, claim, damage, liability, action or expense or any substantially similar loss, claim, damage, liability, action or expense arising from the sale of such Registrable Securities).

        (c)   Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission to so notify the indemnifying party shall not relieve it from any liability under such subsection except to the extent that the indemnifying party is actually prejudiced by such failure to notify. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party, and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any other legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation. Notwithstanding the foregoing, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified person unless the indemnifying party and the indemnified party shall have mutually agreed to the contrary or the named parties in any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interest between them. It is understood and agreed that the indemnifying party shall not, in connection with any proceeding or related proceeding, be liable for the fees and expenses of more than one separate firm (in addition to any one firm of local counsel for each jurisdiction) retained by the indemnified persons for all indemnified persons and that all such fees and expenses of such separate counsel shall be reimbursed as they are incurred. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, which consent shall not be unreasonably denied, withheld, conditioned or delayed, but if settled with such consent or if there shall be a judgment for the plaintiff, the indemnifying party agrees to indemnify each indemnified party from and against any loss or liability by reason of such settlement or judgment. No indemnifying party shall, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to (or an admission of) fault, culpability or a failure to act, by or on behalf of any indemnified party.

        (d)   The indemnification provided for under this Agreement will remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling Person of such indemnified party and will survive the registration and sale of any securities by any Person entitled to any indemnification hereunder and the expiration or termination of this Agreement.

19

---

        (e)   If the indemnification provided for in Section 5.1(a) or Section 5.1(b) is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any loss, liability, claim, damage or expense referred to therein, then the indemnifying party, in lieu of indemnifying such indemnified party thereunder, will contribute to the amount paid or payable by such indemnified party as a result of such loss, liability, claim, damage or expense in such proportion as is appropriate to reflect the relative fault of the indemnifying party, on the one hand, and of the indemnified party, on the other hand, in connection with the statements or omissions or violations that resulted in such loss, liability, claim, damage or expense, as well as any other relevant equitable considerations. The relevant fault of the indemnifying party and the indemnified party will be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. Notwithstanding the foregoing, the amount any Investor shall be obligated to contribute pursuant to this Section 5.1(e) shall be limited to an amount equal to the net proceeds received by such Investor from the sale of its Registrable Securities pursuant to the offering which gives rise to such obligation to contribute (less the aggregate amount of any damages that the Investor has otherwise been required to pay in respect of such loss, claim, damage, liability, action or expense or any substantially similar loss, claim, damage, liability, action or expense arising from the sale of such 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.
