This Note is subject to the following provisions, terms and conditions:

ARTICLE 1— PAYMENT

Section 1.1                                   Maturity.  Subject to the acceleration provisions of Section 3.2 and the conversion provisions of Section 2.1 and Section 2.2, this Note shall be paid in full on the date of the earliest to occur of the following (such earliest date being hereinafter referred to as the “Maturity Date”): (a) ten (10) days following written demand from the Majority Holders made to the Company at any time after August 1, 2014, (b) the consummation of a Sale Transaction (as defined below), or (c) a liquidation, dissolution or winding up of the Company.  As used herein, “Sale Transaction” means the closing of: (i) a merger or consolidation or any other transaction or series of related transactions (other than a future equity financing of the Company) in which the Company’s stockholders immediately prior to the transaction do not own, directly or indirectly, more than 50% of the capital stock of the surviving corporation (or equivalent outstanding equity interests in any other type of entity), (ii) the sale or transfer of all or substantially all of the assets of the Company or (iii) any other event that would be considered a “Deemed Liquidation Event” pursuant to the Company’s Second Amended and Restated Certificate of Incorporation, as amended, as it may be amended and/or restated and then in effect.  In the event that the Company becomes a party to a Sale Transaction, the Company shall notify the holders of the Notes of such Sale Transaction as soon as reasonably practicable prior to the closing of such Sale Transaction.

Section 1.2                                   Prepayment.  This Note may not be prepaid by the Company, in whole or in part, without the prior written consent of the Majority Holders.

Section 1.3                                   Pro Rata Payments.  All payments made by the Company with respect to any of the Notes shall be made pro rata to the holders of all of the Notes in accordance with the respective principal amounts outstanding thereunder.

ARTICLE 2— CONVERSION

Section 2.1                                   Automatic Conversion upon Qualified Financing.  If, at any time prior to August 1, 2014 while this Note is outstanding, the Company concludes an equity financing where at least $45,000,000 or such lesser amount as shall be approved by the Majority Holders (excluding amounts converted under the Notes) is raised from investors, whether or not such investors are then holders of any debt or equity securities of the Company or any other equity financing as a result of which all outstanding Preferred Stock of the Company is automatically converted into Common Stock (as defined below) (a “Qualified Financing”), the entire unpaid principal amount outstanding under this Note and the other Notes and accrued interest thereon shall be automatically converted, upon the closing of the Qualified Financing, into shares of the equity security issued in the Qualified Financing (the “Qualified Financing Securities”) at the Applicable Conversion Price.  As used herein, the “Applicable Conversion Price” means the following price per share: equal to (a) in the case of a Qualified Financing that is an underwritten public offering of shares of Common Stock of the Company (the “Common Stock”) (a “Public Offering”), the purchase price at which shares of the Common Stock are sold by the Company to the public in such Public Offering and (b) in the case of all Qualified Financings other than a

2

Public Offering, 90% of the price per share of the Qualified Financing Securities sold in the Qualified Financing.  The Qualified Financing Securities shall otherwise be issued on terms and conditions that apply to the Qualified Financing.

Section 2.2                                   Optional Conversion into Series C Preferred Stock.  (i) If the Company does not consummate a Qualified Financing prior to August 1, 2014, at any time thereafter, or (ii) immediately prior to, and conditioned upon the effectiveness of, a Sale Transaction, the Majority Holders may elect, upon written notice to the Company, to cause the entire unpaid principal amount outstanding under this Note and the other Notes and all accrued interest thereon to be converted into shares of the Company’s Series C Convertible Preferred Stock (the “Series C Shares”).  In the case of conversion pursuant to this Section 2.2, the conversion price shall be equal to $15.00 per share (as adjusted for any stock splits, stock dividends, recapitalizations or the like with respect to such shares).  The Series C Shares shall otherwise be issued pursuant to a mutually acceptable conversion agreement and otherwise subject to the same terms and conditions that apply to the Series C Shares that are issued and outstanding at the time of conversion.

Section 2.3                                   Surrender of Note; Issuance of Stock Certificates.  As promptly as practicable after the conversion of this Note as provided in Section 2.1 or Section 2.2, the Holder shall surrender this Note to the Company for cancellation, whereupon the Company shall issue and deliver to the Holder, in the name of the Holder, a certificate or certificates for the number of full shares of the Company’s capital stock issuable upon the conversion of this Note.  In the case of a Public Offering, in lieu of issuing certificates, the Company may, if agreed by the Holder, deliver other evidence of the issuance of the Common Stock into which this Note is converted to the Holder (i.e., book entry issuance).  Notwithstanding any failure on the part of the Holder to deliver this Note as aforesaid, upon the occurrence of the applicable conversion event pursuant to Section 2.1 or Section 2.2, this Note shall no longer be deemed to be outstanding, and the Holder, conditioned upon the Holder’s compliance with this Section 2, shall be deemed to be the holder of the securities into which this Note was so converted effective as of such conversion.

Section 2.4                                   No Fractional Shares.  No fractional shares shall be issued upon conversion of this Note.  If conversion of this Note would result in the issuance of a fractional share, the amount payable under this Note that therefore cannot be applied to the purchase of the shares purchasable upon conversion shall be returned to the Holder by the Company.

ARTICLE 3 - SUBORDINATION

Section 3.1                                   Subordination of Note to Senior Indebtedness.  All indebtedness evidenced by this Note shall be subordinated and junior in right and time of payment to the prior payment in full of all amounts due under all indebtedness of the Company for money that it borrows from financial institutions and other third-party lenders and to the Company’s obligations under equipment leases (the “Senior Indebtedness”).

Section 3.2                                   No Payments on Note Unless Senior Indebtedness Provided for or During Defaults on Senior Indebtedness.  No payment under this Note shall be made by the Company unless full payment of amounts then due under the Senior Indebtedness has been made

or provided for by the Company.  No payment under this Note shall be made by the Company if making such payment would violate any terms of the Senior Indebtedness.

Section 3.3                                   No Limitation on Right to Convert.  Nothing set forth in this Article 3 shall be deemed to limit the right of the Holder to convert this Note into equity of the Company in accordance with the terms of Article 2.
