 - 3 -









 (a) Purchaser has the full power and authority to execute and deliver this
Agreement and to perform all of its obligations hereunder and thereunder, and to purchase, acquire and accept delivery of the Series G Units. 
 (b) The Series G Units are being acquired for Purchaser’s own account and not with a view to, or intention of, distribution thereof in violation of the 1933 Act, or any applicable state securities
laws. 
 (c) Purchaser will not make any sale, transfer or other disposition of the Series G Units in violation
of the 1933 Act, the 1934 Act, as amended, the rules and regulations promulgated thereunder or any applicable state securities laws. 
 (d) Purchaser is sophisticated in financial matters and is able to evaluate the risks and benefits of an investment in the Series G Units. Purchaser understands and acknowledges that such investment is a
speculative venture, involves a high degree of risk and is subject to complete risk of loss. Purchaser has carefully considered and has, to the extent Purchaser deems necessary, discussed with Purchaser’s professional legal, tax, accounting and
financial advisers the suitability of its investment in the Series G Units. 
 (e) Purchaser is able to bear the
economic risk of its investment in its Series G Units for an indefinite period of time because the Series G Units have not been registered under the 1933 Act and, therefore, cannot be sold unless subsequently registered under the 1933 Act or an
exemption from such registration is available. Purchaser: (i) understands and acknowledges that the Series G Units being issued to Purchaser have not been registered under the 1933 Act, nor under the securities laws of any state, nor under the
laws of any other country and (ii) recognizes that no public agency has passed upon the accuracy or adequacy of any information provided to Purchaser or the fairness of the terms of its investment in the Series G Units. 

(f) Purchaser has had an opportunity to ask questions and receive answers concerning the terms and conditions of the
offering of the Series G Units and has had full access to such other information concerning the Company as has been requested. 
 (g) This Agreement constitutes the legal, valid and binding obligation of Purchaser, enforceable in accordance with its terms, and the execution, delivery and performance of this Agreement by Purchaser
does not and will not conflict with, violate or cause a breach of any agreement, contract or instrument to which Purchaser is a party or any judgment, order or decree to which Purchaser is subject. 

(h) Purchaser became aware of the offering of the Series G Units other than by means of general advertising or general
solicitation. 
 (i) Purchaser is an “accredited investor” as that term is defined under
the 1933 Act and Regulation D promulgated thereunder, as amended by Section 413 of the Private Fund Investment Advisers Registration Act of 2010 and any applicable rules or regulations or interpretations thereof promulgated by the SEC or
its staff. 

  
 - 4 -









 (j) Purchaser acknowledges that the certificates for the Series G Preferred
Stock and Common Stock comprising the Series G Units will contain a legend substantially as follows: 
 “THE SECURITIES REPRESENTED BY THIS
CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR THE SECURITIES LAWS OF ANY STATE. THE SECURITIES MAY NOT BE TRANSFERRED EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT
AND APPLICABLE STATE SECURITIES LAWS OR PURSUANT TO AN APPLICABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF SUCH ACT AND SUCH LAWS. 
 THE
COMPANY MAY REQUEST A WRITTEN OPINION OF COUNSEL (WHICH OPINION AND COUNSEL SHALL BE REASONABLY SATISFACTORY TO THE COMPANY) TO THE EFFECT THAT REGISTRATION IS NOT REQUIRED IN CONNECTION WITH AN OFFER, SALE OR TRANSFER OF THE SECURITIES REPRESENTED
BY THIS CERTIFICATE.” 
 Subject to any lock-up or other similar agreement that may apply to the Series G Units, the
requirement that the Series G Units contain the legend set forth in clause (j) above shall cease and terminate upon the earlier of (i) when such shares are transferred pursuant to Rule 144 under the 1933 Act or (ii) when such
securities are transferred in any other transaction if the transferor delivers to the Company a written opinion of counsel (which opinion and counsel shall be reasonably satisfactory to the Company) to the effect that such legend is no longer
necessary in order to protect the Company against a violation by it of the 1933 Act upon any sale or other disposition of such securities without registration thereunder. Upon the consummation of an event described in (i) or (ii) above,
the Company, upon surrender of certificates containing such legend, shall, at its own expense, deliver to the holder of any such securities as to which the requirement for such legend shall have terminated, one or more new certificates evidencing
such securities not bearing such legend. 
 6. Exchange for Newly Issued Securities. 

At any time on or prior to November 17, 2013, if the Company issues any securities (whether debt, equity or otherwise), other than
pursuant to the Company’s Amended and Restated Equity-Based Compensation Plan or the Company’s 2011 Employee Stock Purchase Plan (or any additional or successor employee equity compensation arrangements) or a Subsequent Transaction (as
defined below), (any such securities, “Additional Securities”) on terms (economic or otherwise) that Purchaser, in its sole reasonable discretion, determines are more favorable than the Series G Units, Purchaser may exchange
all, but not less than all, of its Series G Units for such newly issued Additional Securities. Each Series G Unit to be exchanged shall be valued at the then present Liquidation Value of the Series G Preferred Stock included in such Series G Unit.
The Company shall, as soon as practicable, but in no event later than 10 days prior to the to the issue of Additional Securities, deliver written notice to Purchaser stating (i) the terms of such Additional Securities and (ii) the
Company’s calculation of the number of such Additional Securities that would be issued in exchange for one Series G Unit. If Purchaser determines, pursuant to this Section 6, that such issuance of Additional Securities is on terms
more favorable than the Series G Units, Purchaser shall have 10 days from the receipt of such 

  
 - 5 -









 
notice from the Company to deliver notice to the Company of such determination and if Purchaser elects to exercise its right to exchange its Series G Units pursuant to the terms of this
Section 6, it shall be required to surrender to the Company all certificate(s) evidencing the shares of Series G Preferred Stock and the shares of Common Stock underlying the Series G Units to be exchanged in accordance with this
Section 6. Notwithstanding anything to the contrary herein, if Purchaser elects to exchange its Series G Units pursuant to this Section 6, it shall have the right to enter into such agreements, make such amendments hereto and
take such other actions in order to give effect to this Section 6. For the avoidance of doubt, the rights granted to Purchaser under this Section 6 shall not apply to the Additional Securities issued in a Subsequent
Transaction. 
 7. Subsequent Securities Sales. 
 (a) At least five days prior to the closing of the first sale of any securities of the Company (whether debt, equity or otherwise) that when aggregated with all other securities of the Company (whether
debt, equity or otherwise) issued and sold thereby since December 1, 2011, other than pursuant to the Company’s Amended and Restated Equity-Based Compensation Plan or the Company’s 2011 Employee Stock Purchase Plan (or any additional
or successor employee equity compensation arrangements) or that certain Series G Unit Subscription Agreement, dated as of December 1, 2011, by and among the Company and the other parties thereto, results in gross proceeds to the Company of at
least $50,000,000.00 in the aggregate (a “Subsequent Transaction”), and for so long as Purchaser holds any of the shares of Series G Preferred Stock purchased hereby, the Company shall give notice of such Subsequent
Transaction to Purchaser setting forth the terms and conditions of such Subsequent Transaction. The Company shall not enter into an agreement for a Subsequent Transaction unless such agreement permits the Company to comply with this
Section 7 and Section 4 of the Certificate of Designation of Series G Preferred Stock of the Company dated December 1, 2011 (the “Certificate of Designation”). 

(b) Simultaneous with and subject to the closing of the Subsequent Transaction, if any, Purchaser shall have the right,
but not the obligation: 
  

	 	i.	to the extent not prohibited by the terms of the securities issued in the Subsequent Transaction, to require the Company to use the proceeds of such Subsequent
Transaction to redeem Purchaser’s Series G Preferred Stock in accordance with Section 4(b)(i) of the Certificate of Designation; or 

  

	 	ii.	to elect to convert all or less than all of Purchaser’s Series G Preferred Stock in accordance with Section 4(b)(ii) of the Certificate of Designation (a
“Conversion”). 

  

	 	(c)	 For the avoidance of doubt, if the Series G Preferred Stock is redeemed, repurchased, exchanged or converted, including but not limited to pursuant to
this Section 7 or pursuant to the Company’s rights and obligations under the Certificate of Designation, for any reason other than in connection with an exchange of Series G Units pursuant to Section 6 of this Agreement,
the holder of

such Series G Units shall retain all of the Common Stock that was part of any Series G Unit of which the Series G Preferred Stock is subject to such redemption, repurchase, exchange or
conversion.

its affiliates and the respective representatives, successors and assigns of each of the foregoing from and against any and all losses, damages, liabilities, deficiencies, claims, diminution of value, interest, awards, judgments, penalties, costs
and expenses (including attorneys’ fees, costs and other out-of-pocket expenses incurred in investigating, preparing or defending the foregoing), asserted against, incurred, sustained or suffered by any of the foregoing as a result of, arising
out of or relating to any breach of any representation, warranty or covenant made by the Company and contained in this Agreement and the schedule hereto.
