rights to the Company or a Company Subsidiary to use any Intellectual Property Rights owned by such third party (collectively, the “Intellectual Property Agreements”).

 (v) Internal Controls; Disclosure Controls. The Company and the Company
Subsidiaries maintain a system of internal control over financial reporting (as such term is defined in Rule 13a-15 of the General Rules and Regulations under the Exchange Act) to provide reasonable assurance regarding the reliability of financial
reporting and the preparation of financial statements for external purposes in accordance with GAAP and includes those policies and procedures that (i) pertain to the maintenance of records that in reasonable detail accurately and fairly
reflect the transactions and dispositions of the assets of the Company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and
expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or
disposition of the Company’s assets that could have a material effect on the financial statements of the Company. Since January 1, 2013, there have been no significant changes in the Company’s internal control over financial
reporting. The Company maintains disclosure controls and procedures (as such term is defined in Rule 13a-15 of the General Rules and Regulations under the Exchange Act) that comply with the requirements of the Exchange Act; such disclosure controls
and procedures have been designed to ensure that (i) information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods
specified in the SEC’s rules and forms, and (ii) information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the Company’s management, including
its principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Such disclosure controls and procedures are effective in all material
respects. Since the Company’s certifying officers evaluated the effectiveness of the disclosure controls and procedures of the Company as of the end of the period covered by the most recently filed periodic report under the Exchange Act, there
have been no changes in the Company’s internal control over financial reporting that have materially affected or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

Sarbanes-Oxley Act of 2002 and applicable rules and regulations promulgated by the SEC thereunder.

any direct or indirect unlawful payment to any foreign or domestic government official or employee from corporate funds; (iii) violated or is in violation of any provision of the U.S. Foreign Corrupt Practices Act of 1977, as amended, or any

Section 3. Representations, Warranties and Covenants of the Standby Purchasers. Each Standby Purchaser, severally and not jointly,
hereby represents, warrants and covenants to the Company as of the date hereof and as of the Closing Date (except for the representations and warranties that speak as of a specific date, which shall be made as of such date) as follows: 

(a) Organization; Authority. Such Standby Purchaser is an entity duly organized, validly existing and in good standing under the laws
of the jurisdiction of its organization with the requisite corporate, partnership or other power and authority to enter into and to consummate the transactions contemplated by this Agreement and otherwise to carry out its obligations hereunder. The
purchase by such Standby Purchaser of Standby Shares hereunder has been duly authorized by all necessary corporate, partnership or other action on its part. This Agreement has been duly executed and delivered by such Standby Purchaser and
constitutes the valid and binding obligation of such Standby Purchaser, enforceable against it in accordance with its terms, except as may be limited by (i) applicable bankruptcy, insolvency, reorganization or other laws of general application
relating to or affecting the enforcement of creditors rights generally, and (ii) the effect of rules of law governing the availability of specific performance and other equitable remedies. 

(b) No Public Sale or Distribution. Such Standby Purchaser is acquiring the Standby Shares for its own account and not with a view
towards, or for resale in connection with, the public sale or distribution thereof, except pursuant to sales registered under the Securities Act or under an exemption from such registration and in compliance with applicable federal and state
securities laws, and such Standby Purchaser does not have a present arrangement to effect any distribution of the Standby Shares to or through any person or entity; provided, however, that by making the representations herein, such
Standby Purchaser does not agree to hold any of the Standby Shares for any minimum or other specific term and reserves the right to dispose of the Standby Shares at any time in accordance with or pursuant to a registration statement or an exemption
under the Securities Act.

not affiliated with any broker dealer registered under Section 15(a) of the Exchange Act, or a member of FINRA or an entity engaged in the business of being a broker dealer. 

(d) Experience of the Standby Purchaser. Such Standby Purchaser, either alone or together with its representatives, has such knowledge,
sophistication and experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment in the Standby Shares and has so evaluated the merits and risks of such investment. Such Standby
Purchaser understands that it must bear the economic risk of this investment in the Standby Shares indefinitely, and is able to bear such risk and is able to afford a complete loss of such investment.

as it has deemed necessary of, and to receive answers from, representatives of the Company concerning the terms and conditions of the offering of the Standby Shares and the merits and risks of investing in the Standby Shares, and (ii) access to
information about the Company and the Company Subsidiaries and their respective financial condition, results of operations, business, properties, management and prospects sufficient to enable it to evaluate its investment. Neither any inquiries by
the Standby Purchaser nor any other investigation conducted by or on behalf of such Standby Purchaser or its representatives or counsel shall modify, amend or affect such Standby Purchaser’s right to rely on the truth, accuracy and completeness
of the Disclosure Materials and the Company’s representations and warranties contained in this Agreement.

Review. Such Standby Purchaser understands that no United States federal or state agency or any other government or governmental agency has passed on or made any recommendation or endorsement of the Standby Shares or the fairness or suitability
of the investment in the Standby Shares nor have such authorities passed upon or endorsed the merits of the offering of the Standby Shares. 

(g) No Conflicts. The execution, delivery and performance by such Standby Purchaser of this Agreement and the consummation by such
Standby Purchaser of the transactions contemplated hereby will not (i) result in a violation of the organizational documents of such Standby Purchaser or (ii) conflict with, or constitute a default (or an event which with notice or lapse
of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, any Contract to which such Standby Purchaser is a party, or (iii) result in a violation of any Legal
Requirements (including federal and state securities laws) applicable to such Standby Purchaser, except in the case of clauses (ii) and (iii) above, for such violations that do not otherwise affect the ability of Standby Purchasers to
consummate the transactions contemplated hereby. 
 (h) Restricted Securities. Such Standby Purchaser understands that the Standby
Shares purchased pursuant to the Standby Offering are characterized as “restricted securities” under the U.S. federal securities laws inasmuch as they are being acquired from the Company in a transaction not involving a public offering and
that under such laws and applicable regulations such securities may be transferred or resold without registration under the Securities Act only in certain limited circumstances. Further, the following legends (or similar language) shall be placed on
such certificate(s) representing the shares of Common Stock:

entitled to any banking, broker’s, finder’s or similar fee or commission in connection with the transactions contemplated by this Agreement.

the directors, officers, stockholders, agents, members, partners or employees (and any other Persons with a functionally equivalent role of a Person holding such titles notwithstanding a lack of such title or any other title) of such controlling
persons (each, an “Standby Purchaser Party”) harmless from any and all losses, liabilities, obligations, claims, contingencies, damages, costs and expenses, including all judgments, amounts paid in settlements, court costs and
reasonable attorneys’ fees and costs of investigation that any such Standby Purchaser Party may suffer or incur as a result of or relating to (a) any breach of any of the representations, warranties, covenants or agreements made by the

 14 








 
Party’s representations, warranties or covenants under this Agreement or any agreements or understandings such Standby Purchaser Party may have with any such third party or any material
violations by such Standby Purchaser Party of state or federal securities laws or any conduct by such Standby Purchaser Party which constitutes fraud, gross negligence, willful misconduct or malfeasance). If any action shall be brought against any
Standby Purchaser Party in respect of which indemnity may be sought pursuant to this Agreement, such Standby Purchaser Party shall promptly notify the Company in writing, and the Company shall have the right to assume the defense thereof with

Company, as the case may be, which consent shall not be unreasonably withheld, conditioned or delayed. Any Standby Purchaser Party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the

reasonable period of time to assume such defense and to employ counsel or (iii) in such action there is, in the reasonable opinion of counsel, a material conflict on any material issue between the position of the Company and the position of

Standby Purchaser Party in respect of which indemnity may be sought hereunder, then such Standby Purchaser Party shall have the right to assume the defense of such action with counsel of its own choosing. The indemnification required by this
Section 8 shall be made by periodic payments of the amount thereof during the course of the investigation or defense, as and when bills are received or are incurred. The indemnity agreements contained herein shall be in addition to (x) any
cause of action or similar right of any Standby Purchaser Party against the Company or others, and (y) any liabilities the Company may be subject to pursuant to law.

signed by the party making the same, shall specify the Section of this Agreement pursuant to which it is given or being made and shall be deemed given or made (a) on the date delivered if delivered in person, (b) on the third
