 11 









 
management’s general or specific authorization; and (D) the recorded accountability for assets is compared with existing assets at reasonable intervals and appropriate action is taken
with respect to any differences. Except as disclosed in the SEC Reports, the Company’s internal control over financial reporting is effective and none of the Company, its board of directors and audit committee is aware of any “significant
deficiencies” or “material weaknesses” (each as defined by the Public Company Accounting Oversight Board) in its internal control over financial reporting, or any fraud, whether or not material, that involves management or other
employees of the Company who have a significant role in the Company’s internal controls; and since the end of the latest audited fiscal year, there has been no change in the Company’s internal control over financial reporting (whether or
not remediated) that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting. The Company’s board of directors has, subject to the exceptions, cure periods and the
phase in periods specified in the applicable stock exchange rules (“Exchange Rules”), validly appointed an audit committee to oversee internal accounting controls whose composition satisfies the applicable requirements of the
Exchange Rules and the Company’s board of directors and/or the audit committee has adopted a charter that satisfies the requirements of the Exchange Rules. The Company’s board of directors has validly appointed an audit committee whose
composition satisfies the applicable requirements of Rule 5605(c)(2) of the Nasdaq Listing Standards (the “Nasdaq Rules”) and the Company’s board of directors and/or the audit committee has adopted a charter that satisfies the
requirements of Rule 5605(c)(1) of the Nasdaq Rules. Neither the Company’s board of directors nor the audit committee has been informed, nor is any director of the Company aware, of (A) any significant deficiencies in the design or
operation of the Company’s internal controls which could adversely affect the Company’s ability to record, process, summarize and report financial data or any material weakness in the Company’s internal controls; or (B) any
fraud, whether or not material, that involves management or other employees of the Company who have a significant role in the Company’s internal controls. No relationship, direct or indirect, exists between or among the Company, on the one
hand, and the directors, officers, stockholders, customers or suppliers of the Company, on the other hand, except as described in the SEC Reports which is required to be described in the SEC Reports. The Company has not, directly or indirectly,
extended or maintained credit, or arranged for the extension of credit, or renewed an extension of credit, in the form of a personal loan to or for any of its directors or executive officers in violation of applicable laws, including
Section 402 of the Sarbanes-Oxley Act. The Company has established and maintains disclosure controls and procedures (as defined in Rules 13a-14 and 15d-14 under the Exchange Act) and such controls and procedures are effective in ensuring that
material information relating to the Company is made known to the principal executive officer and the principal financial officer. The Company has utilized such controls and procedures in preparing and evaluating the disclosures in the SEC Reports.

ARTICLE V. 

OTHER AGREEMENTS OF THE PARTIES 
 5.1 Transfer Restrictions. 
 (a) The Securities may only be
disposed of in compliance with state and federal securities laws. In connection with any transfer of Securities other than pursuant to an effective registration statement under the Securities Act or Rule 144, to the Company or to an Affiliate of a
Purchaser or in connection with a pledge as contemplated in Section 5.1(b), the Company may require the transferor thereof to provide to the Company an opinion of counsel selected by the transferor and reasonably acceptable to the
Company, the form and substance of which opinion shall be reasonably satisfactory to the Company, to the effect that such transfer does not require registration of such transferred Securities under the Securities Act. 

(b) The Purchasers agree to the imprinting, so long as is required by this Section 5.1, of a legend on any of
the Securities in the following form: 
 THIS SECURITY HAS NOT BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE COMMISSION OR THE
SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”), AND, ACCORDINGLY, MAY NOT BE OFFERED OR SOLD EXCEPT PURSUANT TO AN EFFECTIVE
REGISTRATION STATEMENT UNDER THE SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM, OR IN A TRANSACTION NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND IN ACCORDANCE WITH APPLICABLE STATE SECURITIES LAWS. THIS
SECURITY MAY BE PLEDGED IN CONNECTION WITH A BONA FIDE MARGIN ACCOUNT. 

  
 20 









 (c) Certificates evidencing the Shares and Warrant Shares shall not contain
any legend (including the legend set forth in Section 5.1(b) hereof), (i) while a registration statement (including the Registration Statement) covering the resale of such security is effective under the Securities Act,
(ii) following any sale of such Shares or Warrant Shares pursuant to Rule 144, (iii) if such Shares or Warrant Shares are eligible for sale under Rule 144, without the requirement for the Company to be in compliance with the current public
information required under Rule 144 as to such Shares and Warrant Shares and without volume or manner-of-sale restrictions, or (iv) if such legend is not required under applicable requirements of the Securities Act (including judicial
interpretations and pronouncements issued by the staff of the Commission). The Company shall cause its counsel to issue a legal opinion to the Transfer Agent promptly after the Effective Date if required by the Transfer Agent to effect the removal
of the legend hereunder. If all or any portion of a Warrant is exercised at a time when there is an effective registration statement to cover the resale of the Warrant Shares, or if such Shares or Warrant Shares may be sold under Rule 144 and the
Company is then in compliance with the current public information required under Rule 144, or if the Shares or Warrant Shares may be sold under Rule 144 without the requirement for the Company to be in compliance with the current public information
required under Rule 144 as to such Shares or Warrant Shares or if such legend is not otherwise required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the Commission)
then such Warrant Shares shall be issued free of all legends. The Company agrees that following the Effective Date or at such time as such legend is no longer required under this Section 5.1(c), it will, no later than three Trading Days
following the delivery by a Purchaser to the Company or the Transfer Agent of a certificate representing Shares or Warrant Shares, as the case may be, issued with a restrictive legend (such third Trading Day, the “Legend Removal
Date”), deliver or cause to be delivered to such Purchaser a certificate representing such shares that is free from all restrictive and other legends. The Company may not make any notation on its records or give instructions to the Transfer
Agent that enlarge the restrictions on transfer set forth in this Section 5.1. Certificates for Securities subject to legend removal hereunder shall be transmitted by the Transfer Agent to the Purchaser by crediting the account of the
Purchaser’s prime broker with the Depository Trust Company System as directed by such Purchaser. 
 5.2 Furnishing of
Information; Public Information. Until the earliest of the time that (i) no Purchaser owns Securities or (ii) the Warrants have expired, the Company covenants to maintain the registration of the Common Stock under Section 12(b) of
the Exchange Act and to timely file (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to the Exchange Act. 

5.3 Integration. The Company shall not sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any
security (as defined in Section 2 of the Securities Act) that would be integrated with the offer or sale of the Securities in a manner that would require the registration under the Securities Act of the sale of the Securities or that would be
integrated with 

  
 21 









 
the offer or sale of the Securities for purposes of the rules and regulations of Nasdaq such that it would require shareholder approval prior to the closing of such other transaction unless
shareholder approval is obtained before the closing of such subsequent transaction. The Purchasers shall take no action to become a group such that any transactions contemplated by this Agreement would require shareholder approval prior to Closing.

 5.4 Securities Laws Disclosure; Publicity. The Company shall (a) by 9:30 a.m. (New York City time) on the Trading
Day immediately following the date hereof, issue a press release disclosing the material terms of the transactions contemplated hereby in a form reasonably satisfactory to the Principal Purchasers, and (b) file a Current Report on Form 8-K,
including the Transaction Documents as exhibits thereto, with the Commission within the time required by the Exchange Act. The Company shall consult with the Principal Purchasers in issuing any other press releases with respect to the transactions
contemplated hereby, and the Company shall not issue any such press release nor otherwise make any such public statement without the prior consent of the Principal Purchasers (which consent shall not unreasonably be withheld or delayed) or, with
respect to the public disclosure of the identity of any Purchaser, the prior consent of such Purchaser, except if such disclosure is required by law, in which case the Company shall promptly provide the Purchasers with prior notice of such public
statement or communication. 
 5.5 Shareholder Rights Plan. Solely to the extent that it would impair the ability of any
Purchaser to receive Securities under the Transaction Documents, no claim will be made or enforced by the Company or, with the consent of the Company, any other Person, that any Purchaser is an “Acquiring Person” under any control share
acquisition, business combination, poison pill (including any distribution under a rights agreement) or similar anti-takeover plan or arrangement in effect or hereafter adopted by the Company, or that any Purchaser could be deemed to trigger the
provisions of any such plan or arrangement. 
 5.6 Use of Proceeds. The Company shall use the net proceeds from
the sale of the Securities hereunder for funding operations or for working capital or other general corporate purposes. 

5.7 Indemnification of Purchasers. Subject to the provisions of this Section 5.7, the Company will indemnify and hold
each Purchaser and its directors, officers, shareholders, members, partners, employees and agents (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),
each Person who controls such Purchaser (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, shareholders, 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, a “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 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 Company in this Agreement or in the other Transaction Documents or (b) any action instituted against the Purchaser
Parties in any capacity, or any of them or their respective Affiliates, by any stockholder of the Company 

  
 22 









 
who is not an Affiliate of such Purchaser Parties, with respect to any of the transactions contemplated by the Transaction Documents (unless such action is based upon a breach of such Purchaser
Party’s representations, warranties or covenants under the Transaction Documents or any agreements or understandings such Purchaser Parties may have with any such stockholder or any violations by such Purchaser Parties of state or federal
securities laws or any conduct by such Purchaser Parties which constitutes fraud, gross negligence, willful misconduct or malfeasance of such Purchaser Party). If any action shall be brought against any Purchaser Party in respect of which indemnity
may be sought pursuant to this Agreement, such Purchaser Party shall promptly notify the Company in writing, and the Company shall have the right to assume the defense thereof with counsel of its own choosing reasonably acceptable to the Purchaser
Party. Any Purchaser Party shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Purchaser Party except to the extent that
(i) the employment thereof has been specifically authorized by the Company in writing, (ii) the Company has failed after a 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 such Purchaser Party, in which case the Company shall be responsible for the reasonable fees and expenses of no more
than one such separate counsel. The Company will not be liable to any Purchaser Party under this Agreement (y) for any settlement by a Purchaser Party effected without the Company’s prior written consent, which shall not be unreasonably
withheld or delayed; or (z) to the extent, but only to the extent that a loss, claim, damage or liability is attributable to any Purchaser Party’s breach of any of the representations, warranties, covenants or agreements made by such
Purchaser Party in this Agreement or in the other Transaction Documents. The indemnification required by this Section 5.7 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 any cause of action or similar right of any Purchaser Party against the Company or others and any liabilities the Company may be subject to
pursuant to law. 
 5.8 Reservation of Common Stock. The Company has reserved and the Company shall continue to reserve
and keep available at all times, free of preemptive rights, a sufficient number of shares of Common Stock for the purpose of enabling the Company to issue Shares pursuant to this Agreement and Warrant Shares pursuant to any exercise of the
Warrants.  
 5.9 Listing of Common Stock. The Company hereby agrees to use reasonable best efforts to maintain
the listing or quotation of the Common Stock on the Trading Market on which it is currently listed, and, as promptly as practicable following the Closing, to secure the listing of all of the Shares and Warrant Shares on such Trading Market. The
Company further agrees, if the Company applies to have the Common Stock traded on any other Trading Market, it will then include in such application all of the Shares and Warrant Shares, and will take such other action as is necessary to cause all
of the Shares and Warrant Shares to be listed or quoted on such other Trading Market as promptly as possible. The Company will then take all action reasonably necessary to continue the listing or quotation and trading of its Common Stock on a
Trading Market and will comply in all respects with the Company’s reporting, filing and other obligations under the bylaws or rules of the Trading Market. The Purchasers and the Company agree to cooperate in good faith, if necessary, to
restructure the transactions contemplated by the Transaction Documents such that they do not contravene the rules and regulations of Nasdaq; 

  
 23 









 
provided, however, that such restructuring does not impact the economic interests of the Purchasers contemplated by the Transaction Documents. Each Purchaser agrees to provide
information reasonably requested by the Company to comply with this Section 5.9 and Section 3.24. 

5.10 Equal Treatment of Purchasers. No consideration (including any modification of any Transaction Document) shall be offered or
paid to any Person to amend or consent to a waiver or modification of any provision of this Agreement unless the same consideration is also offered to all of the parties to this Agreement. For clarification purposes, this provision constitutes a
separate right granted to each Purchaser by the Company and negotiated separately by each Purchaser, and is intended for the Company to treat the Purchasers as a class and shall not in any way be construed as the Purchasers acting in concert or as a
group with respect to the purchase, disposition or voting of Securities or otherwise. 
 5.11 Form D; Blue Sky Filings.
The Company agrees to timely file a Form D with respect to the Securities as required under Regulation D and to provide a copy thereof, promptly upon request of any Purchaser. The Company shall take such action as the Company shall reasonably
determine is necessary in order to obtain an exemption for, or to qualify the Securities for, sale to the Purchasers at the Closing under applicable securities or “Blue Sky” laws of the states of the United States, and shall provide
evidence of such actions promptly upon request of any Purchaser. Each Purchaser shall provide any information reasonably requested by the Company to comply with Section 5.11. 

5.12 Acknowledgment of Dilution. The Company acknowledges that the issuance of the Securities may result in dilution of the
outstanding shares of Common Stock, which dilution may be substantial under certain market conditions. The Company further acknowledges that its obligations under the Transaction Documents, including, without limitation, its obligation to issue the
Shares and Warrant Shares pursuant to the Transaction Documents, are unconditional and absolute and not subject to any right of set off, counterclaim, delay or reduction, regardless of the effect of any such dilution or any claim the Company may
have against any Purchaser and regardless of the dilutive effect that such issuance may have on the ownership of the other stockholders of the Company. 
 5.13 Other Actions. Except as otherwise set forth in this Agreement, from the date of this Agreement until the earlier to occur of the Closing or the termination of this Agreement in accordance
with the terms hereof, the Company and the Purchasers shall not, and shall not permit any of their respective Affiliates to, take, or agree or commit to take, any action that would reasonably be expected to, individually or in the aggregate,
prevent, materially delay or materially impede the consummation of the transactions contemplated by this Agreement. 
 ARTICLE
VI. 
 TERMINATION 
 6.1 Termination. The obligations of the Company, on the one hand, and the Purchasers, on the other hand, to effect the Closing shall terminate as follows: 

(a) Upon the mutual written consent of the Company and the Purchasers; 

  
 24 









 (b) By the Company if any of the conditions set forth in Section 2.4(a) shall
have become incapable of fulfillment, and shall not have been waived by the Company; 
 (c) By a Purchaser (with respect to
itself only) if any of the conditions set forth in Section 2.4(b) shall have become incapable of fulfillment, and shall not have been waived by such Purchaser; or 
 (d) By either the Company or any Purchaser (with respect to itself only) if the Closing has not occurred on or prior to September 15, 2013; provided, however, that the Principal
Purchasers may, in their sole discretion, extend such date to January 15, 2014 in the event shareholder approval is required; 
 provided,
however, that, except in the case of clause (a) above, the party seeking to terminate its obligation to effect the Closing shall not then be in breach of any of its representations, warranties, covenants or agreements contained in this
Agreement or the other Transaction Documents if such breach has resulted in the circumstances giving rise to such party’s seeking to terminate its obligation to effect the Closing. 

6.2 Notice of Termination; Effect of Termination. In the event of termination by the Company or any Purchaser of its obligations
to effect the Closing pursuant to this ARTICLE VI, written notice thereof shall forthwith be given to the other Purchasers by the Company and the other Purchasers shall have the right to terminate their obligations to effect the Closing upon
written notice to the Company and the other Purchasers. Nothing in this ARTICLE VI shall be deemed to release any party from any liability for any breach by such party of the terms and provisions of this Agreement or the other Transaction
Documents or to impair the right of any party to compel specific performance by any other party of its obligations under this Agreement or the other Transaction Documents. 
 ARTICLE VII. 
 MISCELLANEOUS 

7.1 Fees and Expenses. The parties hereto shall pay their own costs and expenses in connection herewith, except that the Company
shall pay the reasonable fees and expenses of Willkie Farr & Gallagher LLP not to exceed $125,000, regardless of whether the transactions contemplated hereby are consummated; it being understood that Willkie Farr & Gallagher LLP
has only rendered legal advice to Oracle and not to the Company or any other Purchaser in connection with the transactions contemplated hereby, and that each of the Company and each Purchaser has relied for such matters on the advice of its own
respective counsel. Such expenses shall be paid upon demand. The Company shall reimburse the Purchasers upon demand for all reasonable out-of-pocket expenses incurred by the Purchasers, but other than as set forth above in this
Section 7.1 relating to Willkie Farr & Gallagher LLP, shall not reimburse for attorney’s fees. 
 7.2
Entire Agreement. The Transaction Documents, together with the exhibits and schedules thereto, contain the entire understanding of the parties with respect to the subject matter hereof and thereof and supersede all prior agreements and
understandings, oral or written, with respect to such matters, which the parties acknowledge have been merged into such documents, exhibits and schedules. 

  
 25 









 7.3 Notices. Any and all notices or other communications or
deliveries required or permitted to be provided hereunder shall be in writing and shall be deemed given and effective on the earliest of: (a) the date of transmission, if such notice or communication is delivered via facsimile at the facsimile
number set forth on the signature pages attached hereto at or prior to 5:30 p.m. (New York City time) on a Trading Day, (b) the next Trading Day after the date of transmission, if such notice or communication is delivered via facsimile at the
facsimile number set forth on the signature pages attached hereto on a day that is not a Trading Day or later than 5:30 p.m. (New York City time) on any Trading Day, (c) the second (2nd) Trading Day following the date of mailing, if sent by U.S. nationally recognized overnight courier service or

(facsimile 212-728-9592), Attention: Jeffrey Hochman. 
 7.4 Amendments; Waivers. No provision of this Agreement may be
waived, modified, supplemented or amended except in a written instrument signed, in the case of an amendment, by the Company and the Principal Purchasers or, in the case of a waiver, by the party against whom enforcement of any such waived provision
is sought. No waiver of any default with respect to any provision, condition or requirement of this Agreement shall be deemed to be a continuing waiver in the future or a waiver of any subsequent default or a waiver of any other provision, condition
or requirement hereof, nor shall any delay or omission of any party to exercise any right hereunder in any manner impair the exercise of any such right. 
 7.5 Headings. The headings herein are for convenience only, do not constitute a part of this Agreement and shall not be deemed to limit or affect any of the provisions hereof. 

7.6 Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the parties and their successors and
permitted assigns. The Company may not assign this Agreement or any rights or obligations hereunder without the prior written consent of each Purchaser. With the consent of the Company which will not be unreasonably withheld, any Purchaser may
assign any or all of its rights under this Agreement to any Person to whom such Purchaser assigns or transfers any Securities, provided, that a Purchaser may assign any or all rights under this Agreement to an Affiliate of such Purchaser
without the consent of the Company, provided, further that such transferee agrees in writing to be bound, with respect to the transferred Securities, by the provisions of the Transaction Documents that apply to the “Purchasers.”


  
 26 









 7.7 No Third-Party Beneficiaries. This Agreement is intended for the benefit of the
parties hereto and their respective successors and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other Person, except as otherwise set forth in Section 5.7. 

7.8 Governing Law; Jurisdiction. This Agreement shall be governed by, and construed in accordance with, the internal laws of the
State of Delaware without regard to the choice of law principles thereof. Each of the parties hereto irrevocably submits to the exclusive jurisdiction of the state and federal courts located in the State of Delaware for the purpose of any suit,
action, proceeding or judgment relating to or arising out of this Agreement and the transactions contemplated hereby. Service of process in connection with any such suit, action or proceeding may be served on each party hereto anywhere in the world
by the same methods as are specified for the giving of notices under this Agreement. Each of the parties hereto irrevocably consents to the jurisdiction of any such court in any such suit, action or proceeding and to the laying of venue in such
court. Each party hereto irrevocably waives any objection to the laying of venue of any such suit, action or proceeding brought in such courts and irrevocably waives any claim that any such suit, action or proceeding brought in any such court has
been brought in an inconvenient forum. 
 7.9 WAIVER OF JURY TRIAL. IN ANY ACTION, SUIT, OR PROCEEDING IN
ANY JURISDICTION BROUGHT BY ANY PARTY AGAINST ANY OTHER PARTY, THE PARTIES EACH KNOWINGLY AND INTENTIONALLY, TO THE GREATEST EXTENT PERMITTED BY APPLICABLE LAW, HEREBY ABSOLUTELY, UNCONDITIONALLY, IRREVOCABLY AND EXPRESSLY WAIVES FOREVER TRIAL BY
JURY.  
 7.10 Survival. The representations and warranties contained herein shall survive the Closing and the
delivery of the Securities. 
 7.11 Execution. This Agreement may be executed in two or more counterparts, all of which
when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to each other party, it being understood that the parties need not sign the same
counterpart. In the event that any signature is delivered by facsimile transmission or by e-mail delivery of a “.pdf” format data file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf
such signature is executed) with the same force and effect as if such facsimile or “.pdf” signature page were an original thereof. 
 7.12 Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, illegal, void or unenforceable, the remainder of the
terms, provisions, covenants and restrictions set forth herein shall remain in full force and effect and shall in no way be affected, impaired or invalidated, and the parties hereto shall use their commercially reasonable efforts to find and employ
an alternative means to achieve the same or substantially the same result as that contemplated by such term, provision, covenant or restriction. It is hereby stipulated and declared to be the intention of the parties that they would have executed
the remaining terms, provisions, covenants and restrictions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable. 

  
 27 









 7.13 Rescission and Withdrawal Right. Notwithstanding anything to the contrary
contained in (and without limiting any similar provisions of) any of the other Transaction Documents, whenever any Purchaser exercises a right, election, demand or option under a Transaction Document and the Company does not timely perform its
related obligations within the periods therein provided, then such Purchaser may rescind or withdraw, in its sole discretion from time to time upon written notice to the Company, any relevant notice, demand or election in whole or in part without
prejudice to its future actions and rights. 
 7.14 Remedies. In addition to being entitled to exercise all rights
provided herein or granted by law, including recovery of damages, each of the Purchasers and the Company will be entitled to specific performance under the Transaction Documents. The parties agree that monetary damages may not be adequate
compensation for any loss incurred by reason of any breach of obligations contained in the Transaction Documents and hereby agree to waive and not to assert in any action for specific performance of any such obligation the defense that a remedy at
law would be adequate. 
 7.15 Independent Nature of Purchasers’ Obligations and Rights. The obligations of each
Purchaser under any Transaction Document are several and not joint with the obligations of any other Purchaser, and no Purchaser shall be responsible in any way for the performance or non-performance of the obligations of any other Purchaser under
any Transaction Document. Nothing contained herein or in any other Transaction Document, and no action taken by any Purchaser pursuant hereof or thereto, shall be deemed to constitute the Purchasers as a partnership, an association, a joint venture
or any other kind of entity, or create a presumption that the Purchasers are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the Transaction Documents. Each Purchaser shall be entitled
to independently protect and enforce its rights, including, without limitation, the rights arising out of this Agreement or out of the other Transaction Documents, and it shall not be necessary for any other Purchaser to be joined as an additional
party in any proceeding for such purpose. Each Purchaser has been represented by its own separate legal counsel in its review and negotiation of the Transaction Documents. The Company has elected to provide all Purchasers with the same terms and
Transaction Documents for the convenience of the Company and not because it was required or requested to do so by any of the Purchasers.
