 - 5 -









 (b) The Series G Units are being acquired for the 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) The 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) The Purchaser is sophisticated in financial matters and is able to
evaluate the risks and benefits of an investment in the Series G Units. The 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. The Purchaser
has carefully considered and has, to the extent the Purchaser deems necessary, discussed with the Purchaser’s professional legal, tax, accounting and financial advisers the suitability of its investment in the Series G Units. 

(e) The 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. The Purchaser: (i) understands and
acknowledges that the Series G Units being issued to the 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 the Purchaser or the fairness of the terms of its investment in the Series G Units. 
 (f) The 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 the Purchaser, enforceable in accordance with its terms, and the execution, delivery and performance of this Agreement by the Purchaser does not and will not conflict with, violate or cause a breach of any agreement, contract or
instrument to which the Purchaser is a party or any judgment, order or decree to which the Purchaser is subject. 

(h) The Purchaser became aware of the offering of the Series G Units other than by means of general advertising or general
solicitation. 
 (i) The 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. 
 (j) The 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: 

  
 - 6 -









 “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. 

7. PCA Holdings Representation. PCA Holdings represents and warrants to each of the New Purchasers that (i) Pegasus Capital,
LLC (“Pegasus Capital”) is a Delaware limited liability company owned by Mr. Craig M. Cogut, his family members and trusts established for their benefit, (ii) as of the date hereof, PCA Holdings is wholly-owned
by Pegasus Capital, (iii) Pegasus Capital has contributed, as of the date hereof, $10.0 million to PCA Holdings, which amount was used by PCA Holdings to acquire 10,000 Series F Units (which are being exchanged for 10,000 Series G Units in
accordance herewith) and (iv) Pegasus Capital, Mr. Craig M. Cogut and PCA Holdings have no current intention of directly or indirectly selling or otherwise syndicating any such Series G Units being acquired hereby or any securities of
Pegasus Capital or of PCA Holdings (except to the extent PCA Holdings may offer membership interests to current employees, principals or affiliates of Pegasus Capital Advisors, L.P., a Delaware limited partnership). 

8. 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), on terms (economic or otherwise) that PCA


  
 - 7 -









 
Holdings, in its sole reasonable discretion, determines are more favorable than the Series G Units, each Purchaser (including PCA Holdings) may exchange all, but not less than all, of its Series
G Units for such newly issued securities, and any outstanding right to purchase Series G Units shall convert into a right to purchase the newly issued securities on substantially the same terms and conditions as such issuance. 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 such
securities, deliver written notice to each Purchaser stating (i) the terms of such securities and (ii) the Company’s calculation of the number of such securities that would be issued in exchange for one Series G Unit. If PCA Holdings
determines pursuant to this Section 8 that the issuance of securities is on terms more favorable than the Series G Units, PCA Holdings shall have 10 days from the receipt of such notice from the Company to deliver notice to the Company
and each Purchaser of such determination and each Purchaser electing to exercise its right to exchange hereunder 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 8. Notwithstanding anything to the contrary herein, each Purchaser that elects to exchange its Series G Units pursuant to this
Section 8 hereby agrees that PCA Holdings shall have the right to enter into such agreements, make such amendments hereto and take such other actions on behalf of such Purchaser in order to give effect to this Section 8. For
the avoidance of doubt, the rights granted to PCA Holdings under this Section 8 shall not apply to the securities issued in a Subsequent Transaction. 
 9. 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), 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 this Agreement that results in gross proceeds to the Company of at least $50,000,000.00 (a “Subsequent Transaction”), and for so long
as the Series G Preferred Stock remains outstanding, the Company shall give notice of such Subsequent Transaction to the Purchasers 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 9 and Section 4 of the Certificate of Designation. 

(b) Simultaneous with and subject to the closing of the Subsequent Transaction, if any, each holder of Series G Preferred
Stock 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 the Series G Preferred Stock in accordance with Section 4(b)(i) of the Certificate of Designation of Series G Preferred Stock of the Company dated December 1, 2011 (the “Certificate of
Designation”); or 


  
 - 8 -










	 	ii.	to elect to convert all or less than all of the holder’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 9 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 8 of this Agreement, the holder 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. 
 10. Indemnification by the Company. The Company shall save, defend,
indemnify and hold harmless each Purchaser and 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. 

11. General Provisions. 
 (a) Default. A default by any Purchaser of its obligations under Section 2 of this Agreement shall not constitute a default by any other Purchaser under this Agreement and, except with
respect to such defaulting Purchaser, shall not relieve the Company of any of its obligations to any other Purchaser under this Agreement. 
 (b) Choice of Law. The laws of the State of New York without reference to the conflict of laws provisions thereof, will govern all questions concerning the construction, validity and interpretation
of this Agreement. 
 (c) Legal Expenses. Each party to this Agreement shall be solely responsible for its
own expenses incurred in connection with this Agreement and the transactions contemplated hereby, except that the Company agrees that, on the date hereof, it will pay (a) up to $80,000 to Akin Gump Strauss Hauer & Feld LLP
(“Akin Gump”), counsel to PCA Holdings, Holdings II and PPIV, and (b) up to $25,000 in the aggregate to the New Purchasers (excluding Holdings II) or their designees, for legal fees incurred by PCA Holdings, PPIV and the
New Purchasers in connection with this Agreement and the transactions contemplated hereby. Such payments shall be transmitted by wire transfer of immediately available funds to accounts previously designated by Akin Gump and the New Purchasers
(excluding Holdings II), respectively.

 (d) Assignment. At any time and from time to time, without the prior
consent of the Company, PCA Holdings may assign all or less than all of its Option to purchase Series G Units under this Agreement to an assignee of its choosing (an “Assignee”); provided that such Assignee executes
and delivers to the Company a joinder agreement substantially in the form attached hereto as Exhibit A, whereupon such Assignee shall become a Purchaser under this Agreement, with all the rights and obligations associated therewith. For the
avoidance of doubt, PCA Holdings shall not be liable in any way for any of the acts or omissions of any Assignee that PCA Holdings had good faith reason to believe could satisfy its obligations as a Purchaser hereunder. 

(e) Amendment and Waiver. The provisions of this Agreement may be amended and waived only with the prior written
consent of the Company and the Purchasers. 
 (f) Counterparts. This Agreement may be executed in
counterparts, each of which shall be an original and all of which shall constitute a single agreement. 
 (g)
Acceptance by the Company. It is understood that this subscription is not binding on the Company until the Company accepts it, which acceptance is at the sole discretion of the Company and shall be noted by execution of this Agreement by the
Company where indicated. 
 (h) Stockholder. Each Purchaser hereby acknowledges that, once accepted by the
Company, this subscription is not revocable by it. Each Purchaser agrees that, if this subscription is accepted, it shall, and it hereby elects to: (i) become a stockholder of the Company; (ii) be bound by the terms and provisions hereof;
and (iii) execute any and all further documents when and as reasonably requested by the Company in connection with the transactions contemplated by this Agreement.
