affiliates, and any Person acting on their behalf has, directly or indirectly, made any offers or sales of any security or solicited any offers to buy any security, under circumstances that would require registration of the issuance of any of the

stockholder approval provisions, including, without limitation, under the rules and regulations of any exchange or automated quotation system on which any of the securities of the Company are listed or designated. None of the Company, its

(H) all Contingent Obligations in respect of indebtedness of others of the kinds referred to in clauses (A) through (G) above; and (y) “Contingent Obligation” means, as to any Person, any direct or indirect liability,
contingent or otherwise, of that Person with respect to any Indebtedness, lease, dividend or other obligation of another Person if the primary purpose or intent of the Person incurring such liability, or the primary effect thereof, is to provide

respect thereto. 
 (r) Absence of Litigation. Except as set forth in Schedule 3(r), as of the Initial Closing Date there is no

Material Adverse Effect.

 (t) Employee Relations. 

(i)As of the Initial Closing Date, neither the Company nor any of the Guarantors is a party to any collective bargaining agreement. As of the
Initial Closing Date, except as previously publicly disclosed by the Company, no executive officer of the Company or any of the Guarantors has notified the Company or any such Guarantor that such executive officer intends to leave the Company or any
such Guarantor or otherwise terminate such officer’s employment with the Company or any such Guarantor. No executive officer of the Company or any of the Guarantors, to the knowledge of the Company or any of the Guarantors, is, or is now
expected to be, in violation of any material term of any employment contract, confidentiality, disclosure or proprietary information agreement, non-competition agreement, or any other contract or agreement or
any restrictive covenant, and the continued employment of each such executive officer does not subject the Company or any of the Guarantors to any liability with respect to any of the foregoing matters. 

(ii)The Company and the Guarantors are in compliance with all federal, state, local and foreign laws and regulations respecting labor,

title would not reasonably be expected to have a Material Adverse Effect. Any real property and facilities held under lease by the Company and any of the Guarantors are held by them under valid, subsisting and enforceable leases with such exceptions
as are not material and do not interfere with the use made and proposed to be made of such property and buildings by the Company and the Guarantors.

names, service marks, service mark registrations, service names, original works of authorship, patents, patent rights, copyrights, inventions, trade secrets and other intellectual property rights and all applications and registrations therefor
(“Intellectual Property Rights”) and have adequate licenses, approvals and government authorizations for such Intellectual Property Rights necessary to conduct their respective businesses as now conducted, except where such failure
to own or possess such rights or licenses would not reasonably be expected to have a Material Adverse Effect. Each of the United States federally registered patents and patent applications owned by the Company or any of the Guarantors as of the
Initial Closing Date is listed on Schedule 3(v)(i). Except as set forth in Schedule 3(v)(ii), none of the Company’s or the Guarantors’ material Intellectual Property Rights are expected to expire or terminate or are expected

or brought, or to the knowledge of the Company or any of the Guarantors, being threatened, against the Company or any of the Guarantors regarding any of its Intellectual Property Rights which, if

terms and conditions of any such permit, license or approval where, in each of the foregoing clauses (i), (ii) and (iii), the failure to so comply would be reasonably expected to have, individually or in the aggregate, a Material Adverse Effect. The
term “Environmental Laws” means all federal, state, local or foreign laws relating to pollution or protection of human health or the environment (including, without limitation, ambient air, surface water, groundwater, land surface
or subsurface strata), including, without limitation, laws relating to emissions, discharges, releases or threatened releases of chemicals, pollutants, contaminants, or toxic or hazardous substances or wastes (collectively, “Hazardous

and all other material tax returns, reports and declarations required by any jurisdiction to which it is subject, or has obtained an extension thereof (ii) has paid all taxes and other governmental assessments and charges that are material in

may engage in hedging and/or trading activities at various times during the period that the Securities are outstanding, including, without limitation, during the periods that the value of the Conversion Shares, the Interest Shares and/or the Warrant
Shares are being determined or the conversion ratios or exchange ratios of the Notes and/or Warrants are being adjusted or recalculated and (y) such hedging and/or trading activities, if any, could reduce the value of existing
stockholders’ equity interests in the Company both at and after the time the hedging and/or trading activities, to the extent not prohibited by statute, rule or other regulation, are conducted. The Company acknowledges that any such
aforementioned hedging and/or trading activities, provided they comply with the terms of the Confidentiality Agreement and do not otherwise violate statutes, rules, regulations or other laws relating to “insider trading” generally, do not
constitute a breach of this Agreement, the Notes, the Warrants or any of the documents executed in connection herewith.

required under Regulation D to obtain such exemption for or to qualify the Securities for sale. If the Company files a Form D with respect to the Securities, the Company shall provide a copy thereof to each Buyer promptly after such filing. 

(c) Reporting Status. From and after the Form 10-K Filing Date until the date on which the
Investors (as defined in the Registration Rights Agreement) shall have sold all of the Conversion Shares, the Interest Shares and the Warrant Shares and none of the Notes or Warrants are outstanding (the “Reporting
Period”), the Company shall file reports under the Securities Exchange Act of 1934, as amended (the “1934 Act”) even if the 1934 Act or the rules and regulations thereunder would not require the Company to make such
filings, and the Company shall take all actions reasonably necessary to be eligible to register the Conversion Shares, the Interest Shares and the Warrant Shares for resale by the Buyers. 

  
 - 21 - 

 (d) Use of Proceeds. The Company will not use the proceeds from the sale of the Securities
to repurchase any equity or debt securities of the Company, provided, however, that the foregoing shall not prohibit the Company from issuing any Notes or any Rights Offering Notes in exchange for shares of Common Stock. 

(e) Financial Information. The Company agrees to send the following to each Investor during the Reporting Period (i) within one
(1) Business Day after the filing thereof with the SEC, a copy of its Annual Reports on Form 10-K, any Quarterly Reports on Form 10-Q, any Current Reports on Form 8-K (or any analogous reports under the 1934 Act) and any registration statements (other than on Form S-8) or amendments filed pursuant to the 1933 Act, (ii) within one

of the Company generally, contemporaneously with the making available or giving thereof to the stockholders. Notwithstanding the foregoing, the Company shall not be obligated to send or deliver any of the foregoing to the Investors to the extent any

commercial banks in The City of New York are authorized or required by law to remain closed. 
 (f) Reserved. 

(g) Fees. The Company shall reimburse Starboard Value and Opportunity Master Fund Ltd. (a Buyer) or its designee(s) for up to $300,000
of actual, reasonable and documented legal fees and disbursements in connection with the Transactions contemplated by the Transaction Documents, documentation and implementation of the transactions contemplated by the Transaction Documents,
including, without limitation, the Rights Offering, and due diligence in connection therewith), which amount, upon proper presentation of documentation evidencing the same in advance thereof, may be withheld by such Buyer from its purchase price for
any Notes purchased at the Initial Closing or the Additional Closing to the extent not previously reimbursed by the Company. The Company shall be responsible for the payment of any agent’s fees, financial advisory fees, or broker’s
commissions (other than for Persons engaged by any Buyer) relating to or arising out of the transactions contemplated hereby, including, without limitation, any fees or commissions payable to the Agent. The Company shall pay, and hold each Buyer
harmless against, any liability, loss or expense (including, without limitation, reasonable attorney’s fees and out-of-pocket expenses) arising in connection with
any claim relating to any such payment (other than payments due or alleged to be due to any Person engaged by any Buyer). Except as otherwise set forth in the Transaction Documents, each party to this Agreement shall bear its own expenses in
connection with the sale of the Securities to the Buyers. 
 (h) Pledge of Securities. The Company acknowledges and agrees that the
Securities may be pledged by an Investor in connection with a bona fide margin agreement or other loan or financing arrangement that is secured by the Securities. The pledge of Securities shall not be deemed to be a transfer, sale or assignment of
the Securities hereunder, and no 

  
 - 22 - 

 
Investor effecting a pledge of Securities shall be required to provide the Company with any notice thereof or otherwise make any delivery to the Company pursuant to this Agreement or any other
Transaction Document, including, without limitation, Section 2(g) hereof; provided that an Investor and its pledgee shall be required to comply with the provisions of Section 2(g) hereof in order to effect a sale, transfer or
assignment of Securities to such pledgee. The Company hereby agrees to execute and deliver such documentation as a pledgee of the Securities may reasonably request in connection with a pledge of the Securities to such pledgee by an Investor
(provided, however, that such Investor agrees to reimburse the Company for the Company’s expenses incurred in connection therewith, including reasonable legal fees actually incurred). 

(i) Disclosure of Transactions and Other Material Information. On or before 9:30 a.m., New York City time, on the first Business Day
after this Agreement has been executed, the Company shall issue a press release reasonably acceptable to the Buyers (which press release shall contain certain historical financial metrics of the Company as agreed to in writing by the Company and
Starboard Value and Opportunity Master Fund Ltd., including, among other metrics, the current number of shares of Common Stock then outstanding), and file a Current Report on Form 8-K describing the terms of
the transactions contemplated by the Transaction Documents in a form as would be required by the 1934 Act and attaching the material Transaction Documents (including, without limitation, this Agreement, the form of Notes, the form of the Warrant,
and the Registration Rights Agreement as exhibits to such filing, the “8-K Filing”). The Company shall not, and shall cause each of its Subsidiaries and its and each of their respective
officers, directors, affiliates, employees and agents, not to, provide any Buyer with any material, nonpublic information regarding the Company or any of its Subsidiaries from and after the date hereof without the express prior written consent of
such Buyer, including as may be contained in the Confidentiality Agreement. From and after the Form 10-K Filing Date, and provided that, at the applicable time of determination, no individual affiliated with
any Buyer serving on the Board of Directors of the Company was appointed thereto, including pursuant to Section 1(a) of the September Agreement, the Company will not provide any Buyer any material, nonpublic information of or relating to the
Company, any of its Subsidiaries or any of their respective officers, directors, affiliates, employees or agents. If and to the extent the Company does provide any such information, or a Buyer otherwise comes into possession of material non-public information relating to the Company or its Subsidiaries as a result of the receipt or delivery of any notice in accordance with the terms hereof, the Company will comply with its obligations under
Regulation FD under the 1934 Act. 
 (j) Additional Notes. So long as any Buyer beneficially owns any Securities, the Company will not
issue any Notes other than to the Buyers as contemplated hereby and the Company shall not issue any other securities that, as a result of the issuance thereof, would cause a breach or default under the Notes. For the avoidance of doubt, the
foregoing shall not prohibit or limit in any manner the Company’s ability to conduct and complete the Rights Offering and issue the Rights Offering Notes and any securities issuable upon conversion thereof. 

(k) Corporate Existence. So long as any Buyer beneficially owns any Securities, the Company shall maintain its corporate existence. 

  
 - 23 - 

 (l) Reservation of Shares. So long as any Buyer owns any Securities, the Company shall
take all action necessary to at all times have authorized, and reserved for the purpose of issuance, no less than the Required Reserve Amount. If at any time the number of shares of Common Stock authorized and reserved for issuance is not sufficient
to meet the Required Reserve Amount, the Company will as promptly as practicable take all corporate action necessary to authorize and reserve a sufficient number of shares, including, without limitation, calling a special meeting of stockholders to
authorize additional shares to meet the Company’s obligations under Section 3(c), in the case of an insufficient number of authorized shares, obtain stockholder approval of an increase in such authorized number of shares and using
commercially reasonable efforts to cause any shares of Common Stock owned by the Company’s executive officers or directors at the record date therefor to be voted in favor of such an increase in the authorized shares of the Company. 

(m) Conduct of Business. The business of the Company and the Guarantors shall not be conducted in violation of any law, ordinance or
regulation of any governmental entity, except where such violations would not reasonably be expected to result, either individually or in the aggregate, in a Material Adverse Effect; it being understood and agreed that, for purposes hereof, the
Company’s status with respect to the filing of periodic, current and other reports with the SEC, and matters relating thereto and arising therefrom, shall not constitute a Material Adverse Effect. 

(n) Public Information. At any time during the period commencing from the Form 10-K Filing Date
and ending at such time as all of the Securities, if a registration statement is not available for the resale of all of the Securities, may be sold without restriction or limitation pursuant to Rule 144 and without the requirement to be in
compliance with Rule 144(c)(1), if the Company shall (i) fail for any reason to satisfy the requirements of Rule 144(c)(1), including, without limitation, failing to satisfy the current public information requirement under Rule 144(c) or
(ii) if the Company has ever been an issuer described in Rule 144(i)(1)(i) or becomes such an issuer in the future, and the Company shall fail to satisfy any condition set forth in Rule 144(i)(2) (a “Public Information
Failure”) then, as partial relief for the damages to any holder of Securities by reason of any such delay in or reduction of its ability to sell the Securities (which remedy shall not be exclusive of any other remedies available at law or
in equity), the Company shall pay to each such holder an amount in cash equal to one percent (1.0%) of the aggregate Conversion Amount (as defined in the Notes) of such holder’s Securities on the day of a Public Information Failure and on every
thirtieth day (pro rated for periods totaling less than thirty calendar days) thereafter until the earlier of (i) the date such Public Information Failure is cured and (ii) such time that such Public Information Failure no longer prevents
a holder of Securities from selling such Securities pursuant to Rule 144 without any restrictions or limitations. The payments to which a holder shall be entitled pursuant to this Section 4(n) are referred to herein as “Public
Information Failure Payments.” Public Information Failure Payments shall be paid on the earlier of (I) the last day of the calendar month during which such Public Information Failure Payments are incurred and
(II) the third (3rd) Business Day after the event or failure giving rise to the Public Information Failure Payments is cured. In the event the Company fails to make Public Information
Failure Payments in a timely manner, such Public Information Failure Payments shall bear interest at the rate of 1.5% per month (prorated for partial months) until paid in full. 

  
 - 24 - 

 (o) Notice of Disqualification Events. The Company will notify the Buyers in writing,
prior to any Closing Date of (i) any Disqualification Event relating to any Issuer Covered Person and (ii) any event that would, with the passage of time, become a Disqualification Event relating to any Issuer Covered Person. 

(p) Collateral Agent. 

(i) Each Buyer hereby (a) appoints Starboard Value and Opportunity Master Fund Ltd. as the collateral agent hereunder and under the
Security Documents (in such capacity, the “Collateral Agent”), and (b) authorizes the Collateral Agent (and its officers, directors, employees and agents) to take such action on such Buyer’s behalf in accordance with the
terms hereof and thereof. The Collateral Agent shall not have, by reason hereof or pursuant to any Security Documents, a fiduciary relationship in respect of any Buyer. Neither the Collateral Agent nor any of its officers, directors, employees and
agents shall have any liability to any Buyer for any action taken or omitted to be taken in connection hereof or the Security Documents except to the extent caused by its own gross negligence or willful misconduct, and each Buyer agrees to defend,
protect, indemnify and hold harmless the Collateral Agent and all of its officers, directors, employees and agents (collectively, the “Collateral Agent Indemnitees”) from and against any losses, damages, liabilities,
obligations, penalties, actions, judgments, suits, fees, costs and expenses (including, without limitation, reasonable attorneys’ fees, costs and expenses) incurred by such Collateral Agent Indemnitee, whether direct, indirect or consequential,
arising from or in connection with the performance by such Collateral Agent Indemnitee of the duties and obligations of Collateral Agent pursuant hereto or any of the Security Documents. 

(ii) The Collateral Agent shall be entitled to rely upon any written notices, statements, certificates, orders or other documents or any
telephone message believed by it in good faith to be genuine and correct and to have been signed, sent or made by the proper Person, and with respect to all matters pertaining to this Agreement or any of the other Transaction Documents and its
duties hereunder or thereunder, upon advice of counsel selected by it. 
 (iii) The Collateral Agent may resign from the performance of all
its functions and duties hereunder and under the Notes and the Security Documents at any time by giving at least ten (10) Business Days prior written notice to the Company and each holder of the Notes. Such resignation shall take effect upon
the acceptance by a successor Collateral Agent of appointment as provided below. Upon any such notice of resignation, the holders of a majority of the outstanding principal amount of Notes shall appoint a successor Collateral Agent with the consent
of the Company, such consent not to be unreasonably withheld, conditioned or delayed. Upon the acceptance of the appointment as Collateral Agent, such successor Collateral Agent shall succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Collateral Agent, and the retiring Collateral Agent shall be discharged from its duties and obligations under this Agreement, the Notes and the Security Agreement. After any Collateral Agent’s resignation
hereunder, the provisions of this Section 4(p) shall inure to its benefit. If a successor Collateral Agent shall not have been so appointed within said ten (10) Business Day period, the retiring Collateral Agent shall then appoint a
successor Collateral Agent (with the consent of the Company, such consent not to be unreasonably withheld, conditioned or delayed) who shall serve until such time, if any, as the holders of a majority of the outstanding principal amount of Notes
appoints a successor Collateral Agent as provided above. 

  
 - 25 - 

 (iv) The Company hereby covenants and agrees to take all actions as promptly as practicable
reasonably requested by either the holders of a majority of the outstanding principal amount of Notes or the Collateral Agent (or its successor), from time to time pursuant to the terms of this Section 4(p), to secure a successor Collateral
Agent satisfactory to the Company and such requesting part(y)(ies), including, without limitation, by paying all fees of such successor Collateral Agent, by having the Company agree to indemnify any successor Collateral Agent and by the Company
executing a collateral agency agreement or similar agreement and/or any amendment to the Security Documents reasonably requested or required by the successor Collateral Agent. 

(q) Failure to Issue Additional Notes. In the event that a Buyer delivers an Additional Closing Notice pursuant to
Section 1(b)(ii), and the Company is unable or fails to deliver the Additional Notes pursuant thereto (other than as a result of the failure of a Buyer to satisfy the conditions described in Sections 6(b)(i), (ii) or (iii)), then the Company
shall issue additional Warrants to such Buyer and adjust the Conversion Price and the Interest Rate with respect to the Notes held by such Buyer as follows: 

(i) At the Company’s election (subject to clauses (ii) and (iii) below), the Company shall (A) issue additional Warrants (the
intrinsic value of such Warrants, based on the Make-Whole Stock Price, the “Additional Warrants Value”) identical to the Warrants (other than the issuance date and number of warrant shares) and (B) reduce the Conversion Price
and/or increase the Interest Rate, at the Company’s election, with respect to all Notes held by such Buyer (the value of such adjustments shall be equal to the Fair Value of the Notes after giving effect to such adjustments minus the Fair Value
of the Notes before giving effect to such adjustments, the “Note Adjustment Value”). 
 (ii) The sum of the Additional
Warrants Value and the Note Adjustment Value shall be equal to the Additional Notes Value. 
 (iii) Notwithstanding the foregoing, the
Additional Warrants Value must be equal to or greater than the Note Adjustment Value. 
 (iv) If any Additional Warrants are being issued
pursuant to this Section 4(q), then the shares of Common Stock issuable upon exercise thereof (without regard to any limitation on exercise set forth therein) will be treated as “Registrable Securities” under the Registration Rights
Agreement and be subject to the same registration rights as the shares of Common Stock that would have been issuable upon conversion of the Additional Notes (without giving effect to any conversion that would have been set forth therein) that would
have been issued in the applicable Additional Closing. 
 (v) ”Additional Notes Value” means an amount equal to the sum of
(i) the product of (x) the applicable Additional Share Purchase Price for such Additional Notes not issued and (y) $25.00 (as appropriately adjusted for any stock split, stock dividend, 

  
 - 26 - 

 
stock combination, reclassification or other similar transaction occurring after the date hereof or during such period of determination) minus the Make-Whole Stock Price and (ii) the excess
of (I) the greater of Fair Value of the Additional Notes had they been issued as of the Threshold Date or the Determination Date minus (II) the principal amount of such Additional Notes. 

(vi) ”Determination Date” means the date on which the additional Warrants are issued pursuant to clause (i) above and
the date the adjustments to the Notes pursuant to clause (ii) above are effective. 
 (vii) ”Fair Value” shall be
determined mutually by the Company and such Buyer and shall be calculated using the same methodology and the same assumptions used in the determination of the Final Make-Whole Table (as defined in the Notes). 

(viii) ”Make-Whole Stock Price” shall be equal to the lesser of (x) the Closing Sale Price of the Common Stock on the
Threshold Date and (y) the Closing Sale Price of the Common Stock on the Determination Date. 
 (ix) ”Threshold Date”
means the Trading Day immediately preceding the date on which the Additional Closing Notice is delivered. 
 5. REGISTER; TRANSFER AGENT
INSTRUCTIONS. 
 (a) Register. The Company shall maintain at its principal executive offices (or such other office or agency of
the Company as it may designate by notice to each holder of Securities), a register of the Notes and the Warrants in which the Company shall record the name and address of the Person in whose name the Notes or the Warrants have been issued
(including the name and address of each transferee), the principal amount of Notes held by such Person, the number of Conversion Shares issuable pursuant to the terms of the Notes and the number of Warrant Shares issuable upon exercise of the
Warrants held by such Person. The Company shall keep the register open and available at all times during business hours for inspection of any Buyer or its legal representatives. 

(b) Transfer Agent Instructions. The Company shall issue irrevocable instructions to its transfer agent, and any subsequent transfer
agent, substantially in the form of Exhibit F attached hereto (the “Irrevocable Transfer Agent Instructions”) to issue certificates or credit shares to the applicable balance accounts at DTC, registered in the name of each
Buyer or its respective nominee(s), for the Conversion Shares, the Interest Shares or the Warrant Shares issued at each Closing or upon conversion of the Notes or exercise of the Warrants in such amounts as specified from time to time by each Buyer
to the Company upon conversion of the Notes or exercise of the Warrants. The Company warrants that no instruction other than the Irrevocable Transfer Agent Instructions referred to in this Section 5(b), and any stop transfer instructions to
give effect to Section 2(g) hereof, will be given by the Company to its transfer agent with respect thereto, and that the Securities shall otherwise be freely transferable on the books and records of the Company as and to the extent provided in
this Agreement and the other Transaction Documents. If a Buyer effects a sale, assignment or transfer of the Securities 

  
 - 27 - 

 
in accordance with Section 2(g) hereof, the Company shall permit the transfer and shall promptly instruct its transfer agent to issue one or more certificates or credit shares to the
applicable balance accounts at DTC in such name and in such denominations as specified by such Buyer to effect such sale, transfer or assignment. In the event that such sale, assignment or transfer involves the Conversion Shares, the Interest Shares
or the Warrant Shares sold, assigned or transferred pursuant to an effective registration statement or pursuant to Rule 144, the transfer agent shall issue such Securities to the Buyer, assignee or transferee, as the case may be, without any
restrictive legend. The Company acknowledges that a breach by it of its obligations hereunder will cause irreparable harm to a Buyer. Accordingly, the Company acknowledges that the remedy at law for a breach of its obligations under this
Section 5(b) will be inadequate and agrees, in the event of a breach or threatened breach by the Company of the provisions of this Section 5(b), that a Buyer shall be entitled, in addition to all other available remedies, to an order
and/or injunction restraining any breach and requiring immediate issuance and transfer, without the necessity of showing economic loss and without any bond or other security being required, to the fullest extent enforceable under applicable law.

liability of any party to any other party; provided, however, that if this Agreement is terminated pursuant to this Section 8, the Company shall remain obligated to reimburse Starboard Value and Opportunity Master Fund Ltd. or its
designee(s), as applicable, for the reasonable, actual and documented expenses described in Section 4(g) above; provided that any such reimbursed expenses shall not exceed $150,000. 

9. MISCELLANEOUS. 
 (a)
Governing Law; Jurisdiction; Jury Trial. All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be governed by the internal laws of the State of New York, without giving effect to any
choice of law or conflict of law provision or rule (whether of the State of New York or any other jurisdictions) that 

  
 - 32 - 

 
would cause the application of the laws of any jurisdictions other than the State of New York. Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts
sitting in The City of New York, Borough of Manhattan, for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert
in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action or proceeding is
improper. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof to such party at the address for such notices to it under this Agreement
and agrees that such service shall constitute good and sufficient service of process and notice thereof to the fullest extent enforceable under applicable law. Nothing contained herein shall be deemed to limit in any way any right to serve process
in any manner permitted by law. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE TO, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION WITH OR ARISING OUT OF THIS AGREEMENT OR ANY
TRANSACTION CONTEMPLATED HEREBY. 
 (b) Counterparts. This Agreement may be executed in two or more identical counterparts, each
of which shall be considered one and the same agreement and shall become effective when signed by each party and delivered to the other party. In the event that any signature is delivered by facsimile transmission or by an email which contains a
portable document format (.pdf) file of an executed signature page, such signature page shall be considered duly executed and shall be binding upon the signatory thereto with the same force and effect as if the signature were an original. 

(c) Headings. The headings of this Agreement are for convenience of reference and shall not form part of, or affect the interpretation
of, this Agreement. 
 (d) Severability. If any provision of this Agreement is prohibited by law or otherwise determined to be invalid
or unenforceable by a court of competent jurisdiction, the provision that would otherwise be prohibited, invalid or unenforceable shall be deemed amended to apply to the broadest extent that it would be valid and enforceable, and the invalidity or
unenforceability of such provision shall not affect the validity of the remaining provisions of this Agreement so long as this Agreement as so modified continues to express, without material change, the original intentions of the parties as to the
subject matter hereof and the prohibited nature, invalidity or unenforceability of the provision(s) in question does not substantially impair the respective expectations or reciprocal obligations of the parties or the practical realization of the
benefits that would otherwise be conferred upon the parties. The parties will endeavor in good faith negotiations to replace the prohibited, invalid or unenforceable provision(s) with a valid provision(s), the effect of which comes as close as
possible to that of the prohibited, invalid or unenforceable provision(s). 
 (e) Entire Agreement; Amendments. This Agreement and the
other Transaction Documents supersede all other prior oral or written agreements between the Buyers, the Company, their affiliates and Persons acting on their behalf with respect to the matters discussed herein, and this Agreement, the other
Transaction Documents and the 

  
 - 33 - 

 
instruments referenced herein and therein contain the entire understanding of the parties with respect to the matters covered herein and therein and, except as specifically set forth herein or
therein, neither the Company nor any Buyer makes any representation, warranty, covenant or undertaking with respect to such matters. Nothing contained herein or any other Transaction Documents shall limit, expand or in any way modify the terms and
conditions of the Confidentiality Agreement or that certain Agreement, dated as of September 28, 2017 by and between the Company and Starboard, each of which remains in full force and effect pursuant to the respective terms thereof. Provisions
of this Agreement may be amended and the observance thereof may be waived (either generally or in a particular instance and either retroactively or prospectively), only with the written consent of the Company and the holders of at least a majority
of the aggregate number of Registrable Securities issued or issuable under the Notes and Warrants (without regard to any restriction or limitation on the exercise of the Warrants or conversion of the Notes contained therein) (the “Required
Holders”); provided that any such amendment or waiver that complies with the foregoing but that disproportionately, materially and adversely affects the rights and obligations of any Buyer relative to the comparable rights and
obligations of the other Buyers shall require the prior written consent of such adversely affected Buyer; provided, further, that the provisions of Section 4(p) cannot be amended without the additional prior written approval of
the Collateral Agent or its successor. Any amendment or waiver effected in accordance with this Section 9(e) shall be binding upon each Buyer and holder of Securities and the Company. No such amendment shall be effective to the extent that it
applies to less than all of the Buyers or holders of Securities. No consideration shall be offered or paid to any Person to amend or consent to a waiver or modification of any provision of any of the Transaction Documents unless the same
consideration (other than the reimbursement of legal fees) also is offered to all of the parties to the Transaction Documents, holders of Notes or holders of the Warrants, as the case may be. The Company has not, directly or indirectly, made any
agreements with any Buyers relating to the terms or conditions of the transactions contemplated by the Transaction Documents except as set forth in the Transaction Documents. Without limiting the foregoing, the Company confirms that, except as set
forth in this Agreement, no Buyer has made any commitment or promise or has any other obligation to provide any financing to the Company or otherwise. 

(f) Notices. Any notices, consents, waivers or other communications required or permitted to be given under the terms of this Agreement
must be in writing and will be deemed to have been delivered: (i) upon receipt, when delivered personally; (ii) upon receipt, when sent by facsimile (provided confirmation of transmission is mechanically or electronically generated and
kept on file by the sending party) or by electronic mail; or (iii) one (1) Business Day after deposit with an overnight courier service, in each case properly addressed to the party to receive the same. The addresses, facsimile numbers and e-mail addresses for such communications shall be:

 - 35 - 

 (g) Successors and Assigns. This Agreement shall be binding upon and inure to the benefit
of the parties and their respective successors and assigns, including any purchasers of the Notes or the Warrants. The Company shall not assign this Agreement or any rights or obligations hereunder without the prior written consent of the Required
Holders (which consent shall not be unreasonably withheld), including by way of a Fundamental Transaction (unless the Company is in compliance with the applicable provisions governing Fundamental Transactions set forth in the Notes and the
Warrants). A Buyer may assign some or all of its rights hereunder without the consent of the Company, in which event such assignee shall be deemed to be a Buyer hereunder with respect to such assigned rights; provided, however, that:
(i) such designee shall sign a joinder to this agreement in form and substance reasonably acceptable to the Company agreeing to be bound by the terms and conditions applicable to a Buyer hereunder; and (ii) no Buyer shall assign (and any
such attempted assignment shall be null and void) any Notes or Warrants to any Person reasonably identified by the Company to the Buyer to be a competitor of, or in a similar industry as, the Company. 

(h) No Third Party Beneficiaries. This Agreement is intended for the benefit of the parties hereto and their respective permitted
successors and assigns, and is not for the benefit of, nor may any provision hereof be enforced by, any other Person, except that each Indemnitee shall have the right to enforce the obligations of the Company with respect to Section 9(k). 

(i) Survival. Unless this Agreement is terminated under Section 8, the representations and warranties of the Buyers and the Company
contained in Sections 2 and 3, and the agreements and covenants set forth in Sections 4, 5 and 9 shall survive each Closing and the delivery and exercise of Securities, as applicable. Each Buyer shall be responsible only for its own representations,
warranties, agreements and covenants hereunder. 
 (j) Further Assurances. Each party shall do and perform, or cause to be done and
performed, all such further acts and things, and shall execute and deliver all such other agreements, certificates, instruments and documents, as any other party may reasonably request in order to carry out the intent and accomplish the purposes of
this Agreement and the consummation of the transactions contemplated hereby. 
 (k) Indemnification. 

In consideration of each Buyer’s execution and delivery of the Transaction Documents and acquiring the Securities thereunder and in addition to all of
the Company’s other obligations under the Transaction Documents, the Company shall defend, protect, indemnify and hold harmless each Buyer and each other holder of the Securities and all of their stockholders, partners, members, officers,
directors, employees and direct or indirect investors and any of the foregoing Persons’ agents or other representatives (including, without limitation, those retained in connection with the transactions contemplated by this Agreement)
(collectively, the “Indemnitees”), from and against any and all actions, causes of action, suits, claims, losses, 

  
 - 36 - 

 
costs, penalties, fees, liabilities and damages, and expenses in connection therewith (irrespective of whether any such Indemnitee is a party to the action for which indemnification hereunder is
sought), and including actual and reasonable attorneys’ fees and disbursements (the “Indemnified Liabilities”), incurred by any Indemnitee as a result of, or arising out of, or relating to (a) any misrepresentation or
breach of any representation or warranty made by the Company in the Transaction Documents or any other certificate, instrument or document contemplated hereby or thereby, (b) any breach of any covenant, agreement or obligation of the Company
contained in the Transaction Documents or any other certificate, instrument or document contemplated hereby or thereby or (c) any cause of action, suit or claim brought or made against such Indemnitee by a third party (including for these
purposes a derivative action brought on behalf of the Company) and arising out of or resulting from (i) the execution, delivery, performance or enforcement of the Transaction Documents or any other certificate, instrument or document
contemplated hereby or thereby, (ii) any transaction financed or to be financed in whole or in part, directly or indirectly, with the proceeds of the issuance of the Securities, (iii) any disclosure made by such Buyer pursuant to
Section 4(i), or (iv) the status of such Buyer or holder of the Securities as an investor in the Company pursuant to the transactions contemplated by the Transaction Documents, in each case except for any such losses, costs, penalties,
fees, liabilities, damages, or expenses that have been found by a final, non-appealable judgment of a court of competent jurisdiction to have solely resulted from the gross negligence, material breach or
willful misconduct of such Indemnitee. To the extent that the foregoing undertaking by the Company may be unenforceable for any reason, the Company shall make the maximum contribution to the payment and satisfaction of each of the Indemnified
Liabilities that is permissible under applicable law. 
 Except as otherwise set forth herein, the mechanics and procedures with respect to the rights and
obligations under this Section 9(k) shall be the same as those set forth in Section 6 of the Registration Rights Agreement. 
 (l)
No Strict Construction. The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any party. 

(m) Remedies. Each Buyer and each holder of the Securities shall have all rights and remedies set forth in the Transaction Documents and
all rights and remedies which such holders have been granted at any time under any other agreement or contract and all of the rights which such holders have under any law. Any Person having any rights under any provision of this Agreement shall be
entitled to enforce such rights specifically (without posting a bond or other security), to recover damages by reason of any breach of any provision of this Agreement and to exercise all other rights granted by law. Furthermore, the Company
recognizes that in the event that it fails to perform, observe, or discharge any or all of its obligations under the Transaction Documents, any remedy at law may prove to be inadequate relief to the Buyers. The Company therefore agrees that the
other party shall be entitled to seek temporary and permanent injunctive relief in any such case without the necessity of proving actual damages and without posting a bond or other security. 

  
 - 37 - 

 (n) Rescission and Withdrawal Right. Notwithstanding anything to the contrary contained in
(and without limiting any similar provisions of) the Transaction Documents, whenever any Buyer 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 Buyer 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. 
 (o) Payment Set Aside. To the extent that the Company makes a payment or payments to the Buyers hereunder or pursuant to
any of the other Transaction Documents or the Buyers enforce or exercise their rights hereunder or thereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part thereof are subsequently invalidated, declared to
be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any other Person under any law (including, without limitation, any bankruptcy
law, foreign, state or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if
such payment had not been made or such enforcement or setoff had not occurred. 
 (p) Independent Nature of Buyers’ Obligations and
Rights. The obligations of each Buyer under any Transaction Document are several and not joint with the obligations of any other Buyer, and no Buyer shall be responsible in any way for the performance of the obligations of any other Buyer under
any Transaction Document. Nothing contained herein or in any other Transaction Document, and no action taken by any Buyer pursuant hereto or thereto, shall be deemed to constitute the Buyers as, and the Company acknowledges that it has been advised
that the Buyers do not so constitute, a partnership, an association, a joint venture or any other kind of entity. Each Buyer shall be entitled to independently protect and enforce its rights, including, without limitation, the rights arising out of
this Agreement or out of any other Transaction Documents, and it shall not be necessary for any other Buyer to be joined as an additional party in any proceeding for such purpose.

EXECUTION VERSION 

GUARANTY 
 GUARANTY,
dated as of January 16, 2018, made by the undersigned (together with each other Person that executes a joinder agreement and becomes a “Guarantor” hereunder each a “Guarantor”, and collectively, the
“Guarantors”), in favor of the Collateral Agent and the Holders (each as defined below). 
 W I T
N E S S E T H : 
 WHEREAS, comScore, Inc., a Delaware corporation
(the ”Company”), and each party listed as a “Buyer” on the Schedule of Buyers attached to the Securities Purchase Agreement (together with their respective successors and assigns, each a “Buyer”, and
collectively, the “Buyers”) are parties to that certain Securities Purchase Agreement, dated as of January 16, 2018 (as amended, restated or otherwise modified from time to time, the “Securities Purchase
Agreement”), pursuant to which, among other things, the Buyers shall from time to time purchase from the Company certain senior secured convertible “Notes” (as defined in the Securities Purchase Agreement) (as amended, restated,
replaced, or otherwise modified from time to time, each a “Note” and collectively, the “Notes”); 

WHEREAS, the Buyers have requested, and the Guarantors have agreed, that the Guarantors shall execute and deliver to the Buyers, a guaranty
guaranteeing all of the obligations of the Company under the Securities Purchase Agreement, the Notes and the other “Transaction Documents” (as defined in the Securities Purchase Agreement, the “Transaction Documents”);

 WHEREAS, pursuant to a Pledge and Security Agreement, dated as of the date hereof (as amended, restated or otherwise modified from time
to time, the “Security Agreement”), the Company and the Guarantors have granted to Starboard Value and Opportunity Master Fund Ltd., as collateral agent (in such capacity, the “Collateral Agent”) for the
holders (together with their respective successors and assigns, each a “Holder” and collectively, the “Holders”) of the Securities (as defined in the Securities Purchase Agreement), a security interest in and lien
on certain of their assets to secure their respective obligations under this Guaranty, the Securities Purchase Agreement, the Notes and the other Transaction Documents; and 

WHEREAS, each Guarantor has determined that the execution, delivery and performance of this Guaranty directly benefits, and is in the best
interest of, such Guarantor. 
 NOW, THEREFORE, in consideration of the premises and the agreements herein and for other consideration, the
sufficiency of which is hereby acknowledged, each Guarantor hereby agrees with each Holder as follows: 
 SECTION 1. Definitions.
Reference is hereby made to the Securities Purchase Agreement and the Notes for a statement of the terms thereof. All terms used in this Guaranty, which are defined in the Securities Purchase Agreement or the Notes and not otherwise defined herein,
shall have the same meanings herein as set forth therein. 

 SECTION 2. Guaranty. The Guarantors, jointly and severally, hereby unconditionally and
irrevocably, guaranty (a) the punctual payment, as and when due and payable, by stated maturity or otherwise, of all obligations and any other amounts now or hereafter owing by the Company in respect of the Securities Purchase Agreement, the
Notes and the other Transaction Documents, including, without limitation, all interest that accrues after the commencement of any proceeding commenced by or against any the Company or any Guarantor under any provision of the Bankruptcy Code
(Chapter 11 of Title 11 of the United States Code) or under any other bankruptcy or insolvency law, assignments for the benefit of creditors, formal or informal moratoria, compositions, or extensions generally with creditors, or proceedings
seeking reorganization, arrangement, or other similar relief (an “Insolvency Proceeding”), whether or not the payment of such interest is unenforceable or is not allowable due to the existence of such Insolvency Proceeding, and all
fees, commissions, expense reimbursements, indemnifications and all other amounts due or to become due under any of the Transaction Documents, and any and all expenses (including reasonable counsel fees and expenses) reasonably incurred by the
Holders or the Collateral Agent in enforcing any rights under this Guaranty (such obligations, to the extent not paid by the Company, being the “Guaranteed Obligations”) and (b) the punctual and faithful performance, keeping,
observance and fulfillment by the Company of all of the agreements, conditions, covenants and obligations of the Company contained in the Securities Purchase Agreement, the Notes and the other Transaction Documents. Without limiting the generality
of the foregoing, each Guarantor’s liability hereunder shall extend to all amounts that constitute part of the Guaranteed Obligations and would be owed by the Company to the Holders under the Securities Purchase Agreement and the Notes but for
the fact that they are unenforceable or not allowable due to the existence of an Insolvency Proceeding involving any Guarantor or the Company (each, a “Transaction Party”). 

SECTION 3. Guaranty Absolute; Continuing Guaranty; Assignments. 

(a) The Guarantors, jointly and severally, guaranty that the Guaranteed Obligations will be paid strictly in accordance with the terms of the
Transaction Documents, regardless of any law, regulation or order now or hereafter in effect in any jurisdiction affecting any of such terms or the rights of the Holders with respect thereto. The obligations of each Guarantor under this Guaranty are
independent of the Guaranteed Obligations, and a separate action or actions may be brought and prosecuted against any Guarantor to enforce such obligations, irrespective of whether any action is brought against any Transaction Party or whether any
Transaction Party is joined in any such action or actions. The liability of any Guarantor under this Guaranty shall be irrevocable, absolute and unconditional irrespective of, and each Guarantor hereby irrevocably waives, to the extent permitted by
law, any defenses it may now or hereafter have in any way relating to, any or all of the following: 
 (i) any lack of validity or
enforceability of any Transaction Document or any agreement or instrument relating thereto; 
 (ii) any change in the time, manner or place
of payment of, or in any other term of, all or any of the Guaranteed Obligations, or any other amendment or waiver of or any consent to departure from any Transaction Document, including, without limitation, any increase in the Guaranteed
Obligations resulting from the extension of additional credit to any Transaction Party or otherwise;

 (iii) any taking, exchange, release or non-perfection of
any collateral with respect to the Guaranteed Obligations, or any taking, release or amendment or waiver of or consent to departure from any other guaranty, for all or any of the Guaranteed Obligations; or 

(iv) any change, restructuring or termination of the corporate, limited liability company or partnership structure or existence of any
Transaction Party. 
 This Guaranty shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Guaranteed
Obligations is rescinded or must otherwise be returned by any Holder or any other Person upon the insolvency, bankruptcy or reorganization of any Transaction Party or otherwise, all as though such payment had not been made. 

(b) This Guaranty is a continuing guaranty and shall (i) remain in full force and effect until the complete conversion of all of the
Company’s obligations under the Notes to equity securities of the Company and/or indefeasible payment in full in cash of all obligations under the Notes (together with any matured indemnification obligations as of the date of such conversion
and/or payment, but excluding any inchoate or unmatured contingent indemnification obligations) and payment of all other amounts payable under this Guaranty (excluding any inchoate or unmatured contingent indemnification obligations) and
(ii) be binding upon each Guarantor and its respective successors and assigns. This Guaranty shall inure to the benefit of and be enforceable by the Holders and their respective successors, and permitted pledgees, transferees and assigns.
Without limiting the generality of the foregoing sentence, any Holder may pledge, assign or otherwise transfer all or any portion of its rights and obligations under and subject to the terms of any Transaction Document to any other Person, and such
other Person shall thereupon become vested with all the benefits in respect thereof granted to such Holder herein or otherwise, in each case as provided in the Securities Purchase Agreement or such Transaction Document. Notwithstanding the foregoing
and for the avoidance of doubt, this Guaranty will expire and each Guarantor will be released from its obligation hereunder upon the complete conversion of all of the Company’s obligations under the Notes to equity securities of the Company
and/or indefeasible payment in full in cash of all obligations under the Notes (together with any matured indemnification obligations as of the date of such conversion and/or payment, but excluding any inchoate or unmatured contingent
indemnification obligations) and payment of all other amounts payable under this Guaranty (excluding any inchoate or unmatured contingent indemnification obligations). 

SECTION 4. Waivers. To the extent permitted by applicable law, each Guarantor hereby waives promptness, diligence, notice of acceptance
and any other notice with respect to any of the Guaranteed Obligations and this Guaranty and any requirement that the Holders or the Collateral Agent exhaust any right or take any action against any Transaction Party or any other Person or any
Collateral (as defined in the Security Agreement). Each Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated herein and that the waiver set forth in this
Section 4 is knowingly made in contemplation of such benefits. The Guarantors hereby waive any right to revoke this Guaranty, and acknowledge that this Guaranty is continuing in nature and applies to all Guaranteed
Obligations, whether existing now or in the future. 

  
 - 3 - 

 SECTION 5. Subrogation. No Guarantor may exercise any rights that it may now or hereafter
acquire against any Transaction Party or any other guarantor that arise from the existence, payment, performance or enforcement of any Guarantor’s obligations under this Guaranty, including, without limitation, any right of subrogation,
reimbursement, exoneration, contribution or indemnification and any right to participate in any claim or remedy of the Holders or the Collateral Agent against any Transaction Party or any other guarantor or any Collateral (as defined in the Security
Agreement), whether or not such claim, remedy or right arises in equity or under contract, statute or common law, including, without limitation, the right to take or receive from any Transaction Party or any other guarantor, directly or indirectly,
in cash or other property or by set-off or in any other manner, payment or security solely on account of such claim, remedy or right, unless and until the complete conversion of all of the Company’s
obligations under the Notes to equity securities of the Company and/or indefeasible payment in full in cash of all obligations under the Notes (together with any matured indemnification obligations as of the date of such conversion and/or payment,
but excluding any inchoate or unmatured contingent indemnification obligations) and payment of all other amounts payable under this Guaranty (excluding any inchoate or unmatured contingent indemnification obligations). If any amount shall be paid to
a Guarantor in violation of the immediately preceding sentence at any time prior to the later of the payment in full in cash of the Guaranteed Obligations and all other amounts payable under this Guaranty, such amount shall be held in trust for the
benefit of the Holders and shall forthwith be paid ratably to the Holders to be credited and applied to the Guaranteed Obligations and all other amounts payable under this Guaranty, whether matured or unmatured, in accordance with the terms of the
Transaction Documents, or to be held as collateral for any Guaranteed Obligations or other amounts payable under this Guaranty thereafter arising. If (a) any Guarantor shall make payment to the Holders of all or any part of the Guaranteed
Obligations, and (b) the Holders receive the complete conversion of all of the Company’s obligations under the Notes to equity securities of the Company and/or indefeasible payment in full in cash of all obligations under the Notes
(together with any matured indemnification obligations as of the date of such conversion and/or payment, but excluding any inchoate or unmatured contingent indemnification obligations) and payment of all other amounts payable under this Guaranty
(excluding any inchoate or unmatured contingent indemnification obligations), the Holders will, at such Guarantor’s request and expense, execute and deliver to such Guarantor appropriate documents, without recourse and without representation or
warranty, necessary to evidence the transfer by subrogation to such Guarantor of an interest in the Guaranteed Obligations resulting from such payment by such Guarantor. 

SECTION 6. Representations, Warranties and Covenants. 

(a) Each Guarantor hereby represents and warrants as of the date first written above as follows: 

(i) Each Guarantor (A) has read and understands the terms and conditions of the Securities Purchase Agreement, the Notes and the other
Transaction Documents, and (B) now has and will continue to have independent means of obtaining information concerning the affairs, financial condition and business of the Company and the other Transaction Parties, and has no need of, or right
to obtain from the Collateral Agent or any Holder, any credit or other information concerning the affairs, financial condition or business of the Company or the other Transaction Parties that may come under the control of the Collateral Agent or any
Holder. 

  
 - 4 - 

 (b) Each Guarantor covenants and agrees that until the complete conversion of all of the
Company’s obligations under the Notes to equity securities of the Company and/or indefeasible payment in full in cash of all obligations under the Notes (together with any matured indemnification obligations as of the date of such conversion
and/or payment, but excluding any inchoate or unmatured contingent indemnification obligations) and payment of all other amounts payable under this Guaranty (excluding any inchoate or unmatured contingent indemnification obligations), it will comply
with each of the covenants applicable to it which are set forth in Section 4 of the Securities Purchase Agreement as if each Guarantor were a party thereto. 

SECTION 7. Right of Set-off. Upon the occurrence and during the continuance of any Event
of Default, the Collateral Agent and any Holder may, and is hereby authorized to, at any time and from time to time, without notice to the Guarantors (any such notice being expressly waived by each Guarantor) and to the fullest extent permitted by
law, set-off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other indebtedness at any time owing by any Holder to or for the credit or the
account of any Guarantor against any and all obligations of the Guarantors now or hereafter existing under this Guaranty or any other Transaction Document, irrespective of whether or not Collateral Agent or any Holder shall have made any demand
under this Guaranty or any other Transaction Document and although such obligations may be contingent or unmatured. Collateral Agent and each Holder agrees to notify the relevant Guarantor promptly after any such
set-off and application made by such Holder, provided that the failure to give such notice shall not affect the validity of such set-off and application. The rights of
the Collateral Agent or any Holder under this Section 7 are in addition to other rights and remedies (including, without limitation, other rights of set-off) which the Collateral
Agent or such Holder may have under this Guaranty or any other Transaction Document in law or otherwise. 
 SECTION 8. Notices, Etc.
All notices and other communications provided for hereunder shall be in writing and shall be mailed (by overnight mail or by certified mail, postage prepaid and return receipt requested), telecopied or delivered, if to any Guarantor, to the address
for such Guarantor set forth on the signature page hereto, or if to any Holder, to it at its respective address set forth in the Securities Purchase Agreement; or as to any Person at such other address as shall be designated by such Person in a
written notice to such other Person complying as to delivery with the terms of this Section 8. All such notices and other communications shall be effective (i) if mailed (by certified mail, postage prepaid and return
receipt requested), when received or three Business Days after deposited in the mails, whichever occurs first; (ii) if telecopied, when transmitted and confirmation is received, provided same is on a Business Day and, if not, on the next
Business Day; or (iii) if delivered by hand, upon delivery, provided same is on a Business Day and, if not, on the next Business Day. 

SECTION 9. CONSENT TO JURISDICTION; SERVICE OF PROCESS AND VENUE. ANY LEGAL ACTION OR PROCEEDING WITH RESPECT TO THIS GUARANTY OR ANY
OTHER TRANSACTION DOCUMENT MAY BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK IN THE COUNTY OF NEW YORK OR OF THE UNITED STATES DISTRICT COURT FOR THE SOUTHERN DISTRICT OF NEW 

  
 - 5 - 

 
YORK, AND, BY EXECUTION AND DELIVERY OF THIS AGREEMENT, EACH GUARANTOR HEREBY IRREVOCABLY ACCEPTS IN RESPECT OF ITS PROPERTY, GENERALLY AND UNCONDITIONALLY, THE JURISDICTION OF THE AFORESAID
COURTS. NOTHING HEREIN SHALL AFFECT THE RIGHT OF THE HOLDERS TO SERVICE OF PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR TO COMMENCE LEGAL PROCEEDINGS OR OTHERWISE PROCEED AGAINST EACH GUARANTOR IN ANY OTHER JURISDICTION. ANY GUARANTOR HEREBY
EXPRESSLY AND IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY OBJECTION WHICH IT MAY NOW OR HEREAFTER HAVE TO THE JURISDICTION OR LAYING OF VENUE OF ANY SUCH LITIGATION BROUGHT IN ANY SUCH COURT REFERRED TO ABOVE AND ANY CLAIM THAT
ANY SUCH LITIGATION HAS BEEN BROUGHT IN AN INCONVENIENT FORUM. TO THE EXTENT THAT ANY GUARANTOR HAS OR HEREAFTER MAY ACQUIRE ANY IMMUNITY FROM JURISDICTION OF ANY COURT OR FROM ANY LEGAL PROCESS (WHETHER THROUGH SERVICE OR NOTICE, ATTACHMENT PRIOR
TO JUDGMENT, ATTACHMENT IN AID OF EXECUTION OR OTHERWISE) WITH RESPECT TO ITSELF OR ITS PROPERTY, EACH GUARANTOR HEREBY IRREVOCABLY WAIVES SUCH IMMUNITY IN RESPECT OF ITS OBLIGATIONS UNDER THIS GUARANTY AND THE OTHER TRANSACTION DOCUMENTS. 

SECTION 10. WAIVER OF JURY TRIAL, ETC. EACH GUARANTOR HEREBY WAIVES ANY RIGHT TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING OR
COUNTERCLAIM CONCERNING ANY RIGHTS UNDER THIS GUARANTY OR THE OTHER TRANSACTION DOCUMENTS, OR UNDER ANY AMENDMENT, WAIVER, CONSENT, INSTRUMENT, DOCUMENT OR OTHER AGREEMENT DELIVERED OR WHICH IN THE FUTURE MAY BE DELIVERED IN CONNECTION HEREWITH OR
THEREWITH, OR ARISING FROM ANY FINANCING RELATIONSHIP EXISTING IN CONNECTION WITH THIS GUARANTY OR THE OTHER TRANSACTION DOCUMENTS, AND AGREES THAT ANY SUCH ACTION, PROCEEDING OR COUNTERCLAIM SHALL BE TRIED BEFORE A COURT AND NOT BEFORE A JURY. EACH
GUARANTOR CERTIFIES THAT NO OFFICER, REPRESENTATIVE, AGENT OR ATTORNEY OF ANY HOLDER HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT ANY HOLDER WOULD NOT, IN THE EVENT OF ANY ACTION, PROCEEDING OR COUNTERCLAIM, SEEK TO ENFORCE THE FOREGOING WAIVERS.
EACH GUARANTOR HEREBY ACKNOWLEDGES THAT THIS PROVISION IS A MATERIAL INDUCEMENT FOR THE HOLDERS ENTERING INTO THE OTHER TRANSACTION DOCUMENTS. 

SECTION 11. Taxes. 
 (a)
All payments made by any Guarantor hereunder or under any other Transaction Document shall be made in accordance with the terms of the respective Transaction Document and shall be made without set-off,
counterclaim, deduction or other defense. All such payments shall be made free and clear of and without deduction for any present or future taxes, levies, imposts, deductions, charges or withholdings, and all liabilities with respect thereto,
excluding taxes imposed on the net income of any Holder by the jurisdiction in which such Holder is organized or where it has its principal lending office (all such nonexcluded taxes, levies, imposts, deductions, charges, withholdings and
liabilities, collectively or individually, “Taxes”). If any Guarantor shall be required to deduct or to withhold any Taxes from or in respect of any amount payable hereunder or under any other Transaction Document: 

  
 - 6 - 

 (i) the amount so payable shall be increased to the extent necessary so that after making all
required deductions and withholdings (including Taxes on amounts payable to any Holder pursuant to this sentence) each Holder receives an amount equal to the sum it would have received had no such deduction or withholding been made, 

(ii) such Guarantor shall make such deduction or withholding, 

(iii) such Guarantor shall pay the full amount deducted or withheld to the relevant taxation authority in accordance with applicable law, and

 (iv) as promptly as possible thereafter, such Guarantor shall send the Holders an official receipt (or, if an official receipt is not
available, such other documentation as shall be satisfactory to the Holders, as the case may be) showing payment. In addition, each Guarantor agrees to pay any present or future stamp or documentary taxes or any other excise or property taxes,
charges or similar levies that arise from any payment made hereunder or from the execution, delivery, registration or enforcement of, or otherwise with respect to, this Agreement or any other Transaction Document (collectively, “Other
Taxes”). 
 (b) Each Guarantor hereby indemnifies and agrees to hold the Collateral Agent and each Holder (each an
“Indemnified Party”) harmless from and against Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this Section 11) paid by
any Indemnified Party as a result of any payment made hereunder or from the execution, delivery, registration or enforcement of, or otherwise with respect to, this Agreement or any other Transaction Document, and any liability (including
penalties, interest and expenses for nonpayment, late payment or otherwise) arising therefrom or with respect thereto, whether or not such Taxes or Other Taxes were correctly or legally asserted. This indemnification shall be paid within 30
days from the date on which such Holder makes written demand therefor, which demand shall identify the nature and amount of such Taxes or Other Taxes. 

(c) If any Guarantor fails to perform any of its obligations under this Section 11, such Guarantor shall indemnify
the Collateral Agent and each Holder for any taxes, interest or penalties that may become payable as a result of any such failure. The obligations of the Guarantors under this Section 11 shall survive the termination of
this Guaranty and the payment of the Obligations and all other amounts payable hereunder. 
 SECTION 12. Miscellaneous. 

(a) Each Guarantor will make each payment hereunder in lawful money of the United States of America and in immediately available funds to each
Holder, at such address specified by such Holder from time to time by notice to the Guarantors. 
 (b) No amendment or waiver of any
provision of this Guaranty and no consent to any departure by any Guarantor therefrom shall in any event be effective unless the same shall be in writing and signed by each Guarantor and each Holder, and then such waiver or consent shall be
effective only in the specific instance and for the specific purpose for which given. 

  
 - 7 - 

 (c) No failure on the part of the Collateral Agent or any Holder to exercise, and no delay in
exercising, any right hereunder or under any other Transaction Document shall operate as a waiver thereof, nor shall any single or partial exercise of any right hereunder or under any Transaction Document preclude any other or further exercise
thereof or the exercise of any other right. The rights and remedies of the Collateral Agent and the Holders provided herein and in the other Transaction Documents are cumulative and are in addition to, and not exclusive of, any rights or remedies
provided by law. The rights of the Collateral Agent and the Holders under any Transaction Document against any party thereto are not conditional or contingent on any attempt by the Collateral Agent or any Holder to exercise any of their respective
rights under any other Transaction Document against such party or against any other Person. 
 (d) Any provision of this Guaranty that is
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining portions hereof or affecting the validity or enforceability of
such provision in any other jurisdiction. 
 (e) This Guaranty shall (i) be binding on each Guarantor and its respective successors and
assigns, and (ii) inure, together with all rights and remedies of the Collateral Agent and the Holders hereunder, to the benefit of the Collateral Agent and the Holders and their respective successors, transferees and assigns. Without limiting
the generality of clause (ii) of the immediately preceding sentence, the Collateral Agent and any Holder may assign or otherwise transfer its rights and obligations under the Notes, the Securities Purchase Agreement or any other Transaction
Document to any other Person in accordance with the terms thereof, and such other Person shall thereupon become vested with all of the benefits in respect thereof granted to the Collateral Agent or such Holder, as the case may be, herein or
otherwise. None of the rights or obligations of any Guarantor hereunder may be assigned or otherwise transferred without the prior written consent of each Holder. 

(f) If the Company or any Guarantor shall hereafter create or acquire any wholly-owned domestic subsidiary (other than any such wholly-owned
domestic subsidiary that is a subsidiary of a foreign subsidiary), then such subsidiary shall execute and deliver to the Collateral Agent and the Buyers a joinder to this Guaranty in form and substance reasonably satisfactory to the Collateral Agent
and the Buyers. Upon the execution and delivery of such a joinder by any such subsidiary, such subsidiary shall become a Guarantor hereunder with the same force and effect as if originally named a Guarantor herein. The execution and delivery of any
agreement or instrument adding an additional Guarantor as a party to this Guaranty shall not require the consent of any Guarantor hereunder. The rights and obligations of each Guarantor hereunder shall remain in full force and effect, and shall be
joint and several with each other Guarantor hereunder, notwithstanding the addition of any new Guarantor hereunder, as though such new Guarantor had originally been named a Guarantor hereunder on the date of this Guaranty. 

  
 - 8 - 

 (g) This Guaranty reflects the entire understanding of the transaction contemplated hereby and
shall not be contradicted or qualified by any other agreement, oral or written, entered into before the date hereof. 
 (h) Section headings
herein are included for convenience of reference only and shall not constitute a part of this Agreement for any other purpose. 
 (i) This
Guaranty may be executed by each party hereto on a separate counterpart, each of which when so executed and delivered shall be an original, but all of which together shall constitute one agreement. Delivery of an executed counterpart by facsimile or
other method of electronic transmission shall be equally effective as delivery of an original executed counterpart. 
 (j) THIS GUARANTY
SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS MADE AND TO BE PERFORMED THEREIN WITHOUT REGARD TO CONFLICT OF LAW PRINCIPLES.
