W I T N E S S E T H :

WHEREAS, the Initial Investors have, pursuant to the terms of Note Purchase Agreements dated the date hereof, by and among the Company and the purchasers named therein (the “Purchase Agreements”), inter alia, agreed to purchase 13.0% senior secured convertible PIK notes due 2019 (the “Notes”); and

WHEREAS, the Initial Investors have requested, and the Company has agreed to provide, “piggyback” registration rights with respect to the Class A Units issuable upon conversion of the Notes, subject to the terms and conditions set forth herein.

NOW, THEREFORE, in consideration of the mutual covenants and agreements herein contained, the parties hereto hereby agree as follows:

1. PIGGY-BACK REGISTRATION.

(a) Following a Qualified IPO, if the Company proposes to register any of its Class A Units under the Securities Act (except for the registration of securities to be offered pursuant to an employee benefit plan on Form S-8, pursuant to a registration made on Form S-4, or any successor forms thereto then in effect) and the registration form to be used may be used for the registration of Registrable Securities (a “Piggyback Registration”), it will, at each such time, give prompt written notice to the Investors of its intention to do so.

(b) Upon the written request of an Investor (which request shall specify the number of Registrable Securities intended to be registered or disposed of by such Investor) received within 20 Business Days after the delivery of the Company’s notice of registration, the Company shall, subject to the limitations set forth in this Agreement, use its commercially reasonable efforts to include in such registration under the Securities Act all Registrable Securities which such Investor has so requested to be registered or sold.

(c) If the Piggyback Registration is an underwritten offering, the Company shall select the investment banker(s) and manager(s) that will administer the offering.

(d) If any of the managing underwriters gives the Company its written opinion that the total number or dollar amount of securities requested to be included in the registration exceeds the number of dollar amount of securities that can be sold, the Company will include the securities in the registration in the following order of priority: first, all securities the Company proposes to sell, and second, securities allocated among all selling stockholders of the Company

in proportion to the number of Registrable Securities owned by each such selling stockholder (including the Investors) or in such other proportions as shall consented to by holders of a majority of such Registrable Securities.  All persons whose securities are included in the Piggyback Registration must sell their securities on the same terms and conditions as apply to the securities being sold by the Company.

(e) The Company will pay all registration expenses, other than underwriting discounts and selling commissions, in connection with each Piggyback Registration of Registrable Securities, including the reasonable fees of one counsel to the Selling Investors (as defined below) participating in such Piggyback Registration as a group (selected by a majority in interest of the holders of Registrable Securities who participate in such Piggyback Registration).

2. REGISTRATION PROCEDURES; BEST EFFORTS.  Whenever an Investor requests the registration of any Registrable Securities pursuant to Section 1, subject to the limitations set forth in this Agreement, the Company shall use its commercially reasonable efforts to register and to permit the sale of Registrable Securities in accordance with the intended method of disposition.  To carry out this obligation, the Company shall as expeditiously as possible:

(a) Use its commercially reasonable efforts to prepare and file with the SEC a registration statement on the appropriate form and use its commercially reasonable efforts to cause the registration to become effective.  At least two Business Days before filing a registration statement or prospectus or any amendments or supplements thereto that covers Registrable Securities pursuant to Section 1 hereof, the Company will furnish to counsel to the Investors selling Registrable Securities in such offering (each, a “Selling Investor”, and collectively, the “Selling Investors”) copies of all documents proposed to be filed for such counsel’s review and approval, which approval shall not be unreasonably withheld or delayed;

(b) Notify immediately each Selling Investor of any stop order threatened or issued by the SEC and take all actions reasonably required to prevent the entry of a stop order or if entered to have it rescinded or otherwise removed;

(c) Use its commercially reasonable efforts to prepare and file with the SEC such amendments and supplements to the registration statement and the corresponding prospectus necessary to keep the registration statement effective for 180 days or such shorter period as maybe required to sell all Registrable Securities covered by the registration statement; and comply with the provisions of the Securities Act with respect to the disposition of all securities covered by the registration statement during each period in accordance with the Selling Investors’ intended methods of disposition as set forth in the registration statement;

(d) Furnish to each Selling Investor a sufficient number of copies of the registration statement, each amendment and supplement thereto (in each case including all exhibits), the corresponding prospectus (including each preliminary prospectus), and such other documents as such Selling Investor may reasonably request to facilitate the disposition of its Registrable Securities;

2

(e) Use its commercially reasonable efforts to register or qualify the Registrable Securities subject to registration under securities or blue sky laws of jurisdictions in the United States of America as any Selling Investor requests and will do any and all other acts and things that may be necessary or advisable to enable such Selling Investor to consummate the disposition of its Registrable Securities; provided that the Company shall not be required to qualify to do business or to file a general consent to service of process in any such jurisdictions, unless the Company is already subject to service in such jurisdiction and except as may be required by the Securities Act;

(f) Use its commercially reasonable efforts to cause the Registrable Securities covered by the registration statement to be registered with or approved by those governmental agencies or authorities necessary to enable each Selling Investor to consummate the disposition of its Registrable Securities;

(g) Notify each Selling Investor, at any time when a prospectus is required to be delivered under the Securities Act, of any event as a result of which the prospectus or any document incorporated therein by reference contains an untrue statement of a material fact or omits to state any material fact necessary to make the statements therein not misleading, and will prepare a supplement or amendment to the prospectus or any such document incorporated therein by reference so that thereafter 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 not misleading;

(h) Use its commercially reasonable efforts to cause all Registrable Securities to be listed on each securities exchange, if any, on which similar securities issued by the Company are then listed;

(i) Provide an institutional transfer agent and registrar and a CUSIP number for all Registrable Securities on or before the effective date of the registration statement;

(j) Enter into such customary agreements (including an underwriting agreement in customary form) and use its commercially reasonable efforts to in connection with those agreements as the Selling Investors or the underwriters, if any, reasonably request to expedite or facilitate the disposition of such Registrable Securities;

(k) Make available for inspection by any Selling Investor, any underwriter participating in any disposition pursuant to the registration statement, and any attorney, accountant, or other agent of any Selling Investor or underwriter, all financial and other records, pertinent corporate documents and properties of the Company, and cause the Company’s officers, directors, and employees to supply all information reasonably requested by any Selling Investor, underwriter, attorney, accountant, or agent to exercise their due diligence responsibility in connection with the registration statement; provided that an appropriate confidentiality agreement is executed by any such Selling Investor, underwriter, attorney, accountant, or other agent;

(l) In connection with any underwritten offering, obtain a “comfort” letter from the Company’s independent public accountants in customary form and covering those

3

matters customarily covered by “cold comfort” letters as the Selling Investors or the managing underwriters request (and the letter shall be addressed to Selling Investors); and

(m) Furnish, at the reasonable request of any Selling Investor an opinion of counsel representing the Company for the purposes of the registration, in the form and substance customarily given to underwriters in an underwritten public offering and satisfactory to counsel representing such Selling Investors, addressed to the underwriters, if any, and to such Selling Investors.

3. INFORMATION.  From time to time, the Company may require each Selling Investor to furnish to the Company information regarding the distribution of the securities subject to registration.  Whenever any such Selling Investor has requested that Registrable Securities be registered pursuant to this Agreement, such Selling Investor shall notify the Company, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of the happening of any event as to such Selling Investor as a result of which the prospectus included in the registration statement contains an untrue statement of a material fact or omits any fact necessary to make the statements therein not misleading.

4. MATERIAL CHANGE.  Each Selling Investor agrees that, upon receipt of any notice from the Company of any event as a result of which the prospectus or any document incorporated therein by reference contains an untrue statement of material fact or omits to state any material fact necessary to make the statements therein not misleading, such Selling Investor will discontinue the distribution of Registrable Securities pursuant to any such prospectus until such Selling Investor receives copies of a supplemented or amended prospectus from the Company.  In addition, if the Company requests, the Selling Investor will deliver to the Company (at the Company’s expenses) all copies, other than permanent file copies then in its possession, of the prospectus covering the Registrable Securities current at the time of receipt of the notice.

5. MARKET STANDOFF.  Each Investor agrees that, if requested by the Compnay and an underwriter of Registrable Securities of the Company in connection with any public offering by the Company after a Qualified IPO, not to directly or indirectly offer, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant for the sale, or otherwise dispose of or transfer (i) any Registrable Securities held by it for such period not to exceed ninety (90) days following the effective date of the relevant registration statement in connection with any public offering of Registrable Securities, as such underwriter shall specify reasonably and in good faith.  The foregoing provisions of this Section 5 shall be applicable to the Investors only if all officers and directors and all stockholders individually owning more than one percent (1%) are subject to the same restrictions.

6. INDEMNIFICATION.

(a) To the full extent permitted by law, the Company agrees to indemnify each Selling Investor, its officers and directors, and each person who controls such Selling Investor (within the meaning of the Securities Act and the Exchange Act) against all losses, claims, damages, liabilities and expenses to which any of such persons may become subject under the Securities Act or the Exchange Act arising out of or resulting from (i) any untrue or

4

allegedly untrue statement of material fact contained in any registration statement, prospectus or preliminary prospectus or any omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading or any violation by the Company of the Securities Act or any rule or regulation thereunder applicable to the Company and relating to the action or inaction of the Company in connection with any registration, qualification or compliance, except to the extent the untrue statement or omission resulted from information that the Selling Investor furnished in writing to the Company specifically stating that it is for use in the preparation thereof; or (ii) any violation by the Company of any of the Securities Act or the Exchange Act or any applicable state securities laws, or any rules promulgated under any such acts or laws.  As to any person entitled to indemnity under this Section 6(a), such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such person.

(b) Each Selling Investor will furnish to the Company in writing the information and affidavits that the Company reasonably requests for use in connection with any registration statement or prospectus and each such Selling Investor agrees to indemnify, to the fullest extent permitted by law, the Company, its directors and officers, and each person who controls the Company (within the meaning of the Securities Act and the Exchange Act) against all losses, claims, damages, liabilities and expenses to which any of such persons may become subject under the Securities Act or the Exchange Act resulting from any untrue or allegedly untrue statement of material fact contained in any registration statement, prospectus or preliminary prospectus or any omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that the untrue statement or omission is contained in or omitted from any information or affidavit such Selling Investor furnished in writing to the Company through an instrument duly executed by such Selling Investor specifically stating that it is for use in the preparation of such registration statement, prospectus or preliminary prospectus; provided, however, that the obligations of any Selling Investor hereunder shall be limited to an amount equal to the proceeds received by such Selling Investor from the sale of securities pursuant to the applicable registration statement as contemplated herein. As to any person entitled to indemnity under this Section 6(b), such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such person.

(c) Any person entitled to indemnification under this Section 6 will (x) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification and (y) unless in the indemnifying party’s reasonable judgment a conflict of interest may exist between the indemnified and indemnifying parties with respect to the claim, permit the indemnifying party to assume the defense of the claim with counsel reasonably satisfactory to the indemnified party.  If the indemnifying party does not assume the defense, the indemnifying party will not be liable for any settlement made without its consent (but that consent may not be unreasonably withheld).  No indemnifying party will consent to entry of any judgment or will enter into any settlement that does not include as an unconditional term the claimant’s or plaintiffs release of the indemnified party from all liability concerning the claim or litigation.  An indemnifying party who is not entitled to or elects not to assume the defense of a claim will not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by the indemnifying party with respect to the claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between the indemnified party

5

and any other indemnified party with respect to the claim, in which event the indemnifying party shall be obligated to pay the fees and expenses of additional counsel.

(d) In order to provide for just and equitable contribution to joint liability under the Securities Act in any case in which either (x) any Selling Investor exercising rights under this Agreement, or any controlling person of any such Selling Investor, makes a claim for indemnification pursuant to this Section 6 but it is judicially determined (by the entry of a final judgment or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such case, or (y) contribution under the Securities Act may be required on the part of any such Selling Investor or any such controlling person in circumstances for which indemnification is provided under this Section 6; then, in each such case, the Company and such Selling Investor will contribute to the aggregate losses, claims, damages, liabilities and expenses that they may be subject to (after contribution to others) in such proportion as is appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with the actions that resulted in such losses, claims, damages, liabilities and expenses, as well as any other relevant equitable considerations; provided, however, that no Selling Investor will be required to contribute any amount in excess of the proceeds actually received by such Selling Investor pursuant to the registration statement.  The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact was made by, or relates to information supplied by, the indemnifying party or the indemnified party, and the indemnifying party’s or the indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action.  The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in this Agreement, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding.  The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 6(d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in this Section 6(d).  No person or entity guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any person or entity who was not guilty of such fraudulent misrepresentation.

7. RULE 144 AND RULE 144A; COMPANY OBLIGATIONS.  If the Company files a registration statement pursuant to the requirements of the Securities Act or Section 12 of the Exchange Act, the Company covenants that it will file the reports required to be filed by it under the Securities Act and the Exchange Act and the rules and obligations adopted by the SEC thereunder, and it will take such further action as any Investor reasonably may request, all to the extent required from time to time, to enable such Investor to sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by (i) Rule 144 under the Securities Act as amended from time to time, or (ii) any similar rule or regulation hereafter adopted by the SEC.

8. TERMINATION.  This Agreement shall terminate with respect to any Investor immediately after all of such Investor’s Registrable Securities are freely saleable under Rule 144.

6

9. SUCCESSOR ENTITY.  The Company shall not change its form of organization (i.e., to  a corporation, partnership or other form of entity), or merge or consolidate into any other Person, unless such changed or successor entity agrees to be bound by this Agreement.

10. MOST FAVORED NATION.  If at any time or from time to time the Company proposes to provide registration rights to holders of Class A Units or securities convertible or exchangeable into Class A Units, that are more favorable to such holder than or in excess of those provided to the Investors hereunder, then, the Company shall give such Investors written notice in reasonable detail of such proposed registration rights, such notice to be given no less than 10 Business Days prior to the proposed granting of such registration rights (the “Company Notice”), and, at the option of holders of a majority of the Registrable Securities by written notice to the Company within 10 Business Days of the date of the Company’s notice (the “Investor Notice”), the Company shall, concurrently upon the granting of such registration rights to such holder(s), grant or provide such more favorable registration rights to the Investors.  If the holders of a majority of the Registrable Securities fail to send a timely Investor Notice, the Investors shall be deemed to have waived their rights under this Section 10, but only with respect to the proposed registration rights that are set forth in the Company Notice.
