 Exhibit 10.5 

EXECUTION VERSION 

BRIDGE GUARANTY AGREEMENT 

Bridge Guaranty Agreement (this “Guaranty”) is entered into as of May 12, 2016, by Western Digital Corporation,
a Delaware corporation (the “Parent”), Western Digital Technologies, Inc., a Delaware corporation (the “Borrower”), and the other parties who have executed this Guaranty (the “Subsidiary
Guarantors”; and along with any other parties who execute and deliver to the Administrative Agent (as hereinafter identified and defined) an agreement in the form attached hereto as Exhibit A, being herein referred to
collectively as the “Guarantors” and individually as a “Guarantor”). 
 PRELIMINARY STATEMENTS

 A.         Parent, Borrower, JPMorgan Chase Bank, N.A. (“JPMorgan Chase
Bank”), as Administrative Agent (JPMorgan Chase Bank in such capacity being referred to herein as the “Administrative Agent”), and the other banks and financial institutions party thereto are parties to a Bridge Loan
Agreement dated as of May 12, 2016 (as extended, renewed, amended, restated, refinanced, replaced, amended and restated, supplemented or otherwise modified, the “Bridge Loan Agreement”) pursuant to which JPMorgan Chase Bank and
other banks and financial institutions from time to time party to the Bridge Loan Agreement have provided financial accommodations to the Borrower (JPMorgan Chase Bank, in its individual capacity and such other banks, financial institutions and
lenders being hereinafter referred to collectively as the “Lenders” and individually as a “Lender”). 

B.         The Borrower and one or more of the Guarantors may from time to time be liable to
the Lenders and/or their Affiliates with respect to the Obligations as defined in the Bridge Loan Agreement (the Administrative Agent and the Lenders, together with any Affiliates of the Lenders with respect to the Obligations, as such terms are
defined in the Bridge Loan Agreement, being hereinafter referred to collectively as the “Guaranteed Creditors” and individually as a “Guaranteed Creditor”). 

C.         The obligations of the Lenders to extend such credit are conditioned upon, among other
things, the execution and delivery of this Guaranty. 
 D.         The Subsidiary Guarantors are
direct or indirect Subsidiaries of the Parent; and the Parent provides each of the Borrower and the Guarantors with financial, management, administrative, and/or technical support which enables the Borrower and the Guarantors to conduct their
businesses in an orderly and efficient manner in the ordinary course. 
 E.         Each Guarantor
will benefit, directly or indirectly, from credit and other financial accommodations extended by the Guaranteed Creditors to the Borrower. 

F.         The Intercreditor Agreement governs the relative rights and priorities of the First Lien
Secured Parties (as defined in the Intercreditor Agreement) in respect of the First Lien Security Documents (as defined in the Intercreditor Agreement) and with respect to certain other matters as described therein. 

NOW, THEREFORE, for good and valuable consideration, receipt whereof is hereby acknowledged, the parties hereto hereby agree as follows: 

1.         All capitalized terms used herein without definition shall have the same meanings herein
as such terms have in the Bridge Loan Agreement. 







 2.         Each Guarantor hereby irrevocably and
unconditionally guarantees jointly and severally to the Administrative Agent, for the ratable benefit of the Guaranteed Creditors, the due and punctual payment when due of the Obligations whether now existing or hereafter arising (whether or not any
proceeding under any debtor relief law shall have stayed the accrual of collection of any of the Guaranteed Obligations or operated as a discharge thereof) (and whether arising before or after the filing of a petition in bankruptcy and including all
interest accrued after the petition date), due or to become due, direct or indirect, absolute or contingent, and howsoever evidenced, held or acquired (the “Guaranteed Obligations”). In case of failure by the Borrower or the
Guarantors punctually to pay any Guaranteed Obligations, each Guarantor hereby jointly and severally agrees to make such payment or to cause such payment to be made punctually as and when the same shall become due and payable, whether at stated
maturity, by acceleration or otherwise, and as if such payment were made by the Borrower or other Guarantors. All payments hereunder by any Guarantor shall be made in immediately available funds in Dollars without setoff, counterclaim or other
defense or withholding or deduction of any nature. Notwithstanding anything in this Guaranty to the contrary, the right of recovery against a Guarantor under this Guaranty shall be limited to an aggregate amount equal to the largest amount that
would not render its obligations under this Guaranty subject to avoidance as a fraudulent transfer or conveyance under Section 548 of the Bankruptcy Code of the United States or any comparable provisions of any other applicable law. 

3.         Each Guarantor agrees that, upon demand, such Guarantor will then pay to the
Administrative Agent for the benefit of the Guaranteed Creditors the full amount of the Guaranteed Obligations that is then due (subject to the limitation on the right of recovery from such Guarantor pursuant to the last sentence of Section 2
above) whether or not any one or more of the other Guarantors shall then or thereafter pay any amount whatsoever in respect to their obligations hereunder. 

4.         (a)         Until the Termination Date, the
Guarantors (i) shall have no right of subrogation with respect to such Guaranteed Obligations and (ii) waive any right to enforce any remedy which any of the Guaranteed Creditors or the Administrative Agent now have or may hereafter have
against the Parent, any endorser or any guarantor of all or any part of the Guaranteed Obligations or any other Person, and until such time the Guarantors waive any benefit of, and any right to participate in, any security or collateral given to the
Guaranteed Creditors, the Collateral Agent and the Administrative Agent to secure the payment or performance of all or any part of the Guaranteed Obligations or any other liability of the Parent to the Guaranteed Creditors or the Administrative
Agent. Should any Guarantor have the right, notwithstanding the foregoing, to exercise its subrogation rights, each Guarantor hereby expressly and irrevocably (A) subordinates any and all rights at law or in equity to subrogation,
reimbursement, exoneration, contribution, indemnification or set off that such Guarantor may have to the payment in full in cash of the Guaranteed Obligations until the Termination Date and (B) waives any and all defenses available to a surety,
guarantor or accommodation co-obligor until the Termination Date. Each Guarantor acknowledges and agrees that this subordination is intended to benefit the Administrative Agent and the Guaranteed Creditors and shall not limit or otherwise affect
such Guarantor’s liability hereunder or the enforceability of this Guaranty, and that the Administrative Agent, the Guaranteed Creditors and their respective successors and assigns are intended third party beneficiaries of the waivers and
agreements set forth in this Section 4(a). 
 (b)         Each Guarantor agrees that any and
all claims of such Guarantor against the Borrower or any other Guarantor hereunder (each, an “Obligor”) with respect to any “Intercompany Indebtedness” (as hereinafter defined), any endorser, obligor or any other guarantor
of all or any part of the Guaranteed Obligations, or against any of its properties shall be subordinate and subject in right of payment to the prior payment, in full and in cash, of all Guaranteed Obligations until the Termination Date; provided
that, as long as no Event of Default has occurred and is continuing, such Guarantor may receive payments of principal and interest from any Obligor with respect to Intercompany Indebtedness to the 

  
 -2- 








 
extent not prohibited by the other terms of the Loan Documents. Notwithstanding any right of any Guarantor to ask, demand, sue for, take or receive any payment from any Obligor, all rights, liens
and security interests of such Guarantor, whether now or hereafter arising and howsoever existing, in any assets of any other Obligor shall be and are subordinated to the rights of the Guaranteed Creditors, the Administrative Agent and the
Collateral Agent in those assets. No Guarantor shall have any right to possession of any such asset or to foreclose upon any such asset, whether by judicial action or otherwise, unless and until the Termination Date. If all or any part of the assets
of any Obligor, or the proceeds thereof, are subject to any distribution, division or application to the creditors of such Obligor, whether partial or complete, voluntary or involuntary, and whether by reason of liquidation, bankruptcy, arrangement,
receivership, assignment for the benefit of creditors or any other action or proceeding, or if the business of any such Obligor is dissolved or if substantially all of the assets of any such Obligor are sold, then, and in any such event (such events
being herein referred to as an “Insolvency Event”), any payment or distribution of any kind or character, either in cash, securities or other property, which shall be payable or deliverable upon or with respect to any Indebtedness
of any Obligor to any Guarantor (“Intercompany Indebtedness”) shall be paid or delivered directly to the Administrative Agent for application on any of the Guaranteed Obligations, due or to become due, until the Termination Date.
Should any payment, distribution, security or instrument or proceeds thereof be received by the applicable Guarantor upon or with respect to the Intercompany Indebtedness after any Insolvency Event and prior to the satisfaction of all of the
Guaranteed Obligations and the termination of all financing arrangements pursuant to any Bridge Loan Document among the Borrower and the Guaranteed Creditors, such Guarantor shall receive and hold the same in trust, as trustee, for the benefit of
the Guaranteed Creditors and shall forthwith deliver the same to the Administrative Agent, for the benefit of the Guaranteed Creditors, in precisely the form received (except for the endorsement or assignment of the Guarantor where necessary), for
application to any of the Guaranteed Obligations, due or not due, and, until so delivered, the same shall be held in trust by the Guarantor as the property of the Guaranteed Creditors. If any such Guarantor fails to make any such endorsement or
assignment to the Administrative Agent or the Collateral Agent, the Administrative Agent or the Collateral Agent or any of their officers or employees is irrevocably authorized to make the same. 

5.         (a)       To the extent that any Guarantor shall make
a payment under this Guaranty (a “Guarantor Payment”) which, taking into account all other Guarantor Payments then previously or concurrently made by any other Guarantor, exceeds the amount which otherwise would have been paid by or
attributable to such Guarantor if each Guarantor had paid the aggregate Guaranteed Obligations satisfied by such Guarantor Payment in the same proportion as such Guarantor’s “Allocable Amount” (as defined below) (as determined
immediately prior to such Guarantor Payment) bore to the aggregate Allocable Amounts of each of the Guarantors as determined immediately prior to the making of such Guarantor Payment, then, following the Termination Date, such Guarantor shall
be entitled to receive contribution and indemnification payments from, and be reimbursed by, each other Guarantor for the amount of such excess, pro rata based upon their respective Allocable Amounts in effect immediately prior to such Guarantor
Payment. Notwithstanding any other provision of this Guaranty, the amount guaranteed by each Guarantor hereunder shall be limited to the extent, if any, required so that its obligations hereunder shall not be subject to avoidance under
Section 548 of the Bankruptcy Code or under any applicable state Uniform Fraudulent Transfer Act, Uniform Fraudulent Conveyance Act or similar statute or common law. In determining the limitations, if any, on the amount of any Guarantor’s
obligations hereunder pursuant to the preceding sentence, it is the intention of the parties hereto that any rights of subrogation or contribution which such Guarantor may have under this Guaranty, any other agreement or applicable law shall be
taken into account. 
 (b)         Unless the Guarantors have otherwise agreed on a
different allocation, as of any date of determination, the “Allocable Amount” of any Guarantor shall be equal to the excess of the fair saleable value of the property of such Guarantor over the total liabilities of such Guarantor
(including the maximum amount reasonably expected to become due in respect of contingent liabilities, calculated, 

  
 -3- 








 
without duplication, assuming each other Guarantor that is also liable for such contingent liability pays its ratable share thereof), giving effect to all payments made by such other Guarantors
as of such date in a manner to maximize the amount of such contributions. 
 (c)        This
Section 5 is intended only to define the relative rights of the Guarantors, and nothing set forth in this Section 5 is intended to or shall impair the obligations of the Guarantors, jointly and severally, to pay any amounts as and when the
same shall become due and payable in accordance with the terms of this Guaranty. 
 (d)        The
parties hereto acknowledge that the rights of contribution and indemnification hereunder shall constitute assets of the Guarantor or Guarantors to which such contribution and indemnification is owing. 

(e)        The rights of the indemnifying Guarantors against other Guarantors under this
Section 5 shall be exercisable upon the occurrence of the Termination Date. 

6.        Subject to the terms and conditions of the Bridge Loan Agreement, including, without
limitation, Section 10.10 thereof, each Guaranteed Creditor may, without any notice whatsoever to any of the Guarantors, sell, assign, or transfer all of the Guaranteed Obligations, or any part thereof, or grant participations therein, and in
that event each and every immediate and successive assignee, transferee, or holder of all or any part of the Guaranteed Obligations, shall have the right through the Administrative Agent pursuant to Section 18 hereof to enforce this Guaranty,
by suit or otherwise, for the benefit of such assignee, transferee, holder or participant, as fully as if such assignee, transferee, or holder or participant were herein by name specifically given such rights, powers and benefits; but each
Guaranteed Creditor through the Administrative Agent pursuant to Section 18 hereof shall have an unimpaired right to enforce this Guaranty for its own benefit or any such participant, as to so much of the Guaranteed Obligations that it has not
sold, assigned or transferred. 
 7.         Subject to Section 9.12 of the Bridge Loan
Agreement, this Guaranty is a continuing, absolute and unconditional Guaranty, and shall remain in full force and effect until the Termination Date has occurred. The Guaranteed Creditors may at any time or from time to time release any Guarantor
from its obligations hereunder or effect any compromise with any Guarantor and no such release or compromise shall in any manner impair or otherwise affect the obligations hereunder of the other Guarantors. No release, compromise, or discharge of
any one or more of the Guarantors shall release, compromise or discharge the obligations of the other Guarantors hereunder. 

8.         In case of the dissolution, liquidation or insolvency (howsoever evidenced) of, or the
institution of bankruptcy or receivership proceedings against the Borrower or any Guarantor, in each case, that would permit or cause the acceleration of the indebtedness under the Bridge Loan Agreement, all of the Guaranteed Obligations which are
then existing may be declared by the Administrative Agent immediately due or accrued and payable from the Guarantors at such time as the obligations are accelerated. 

9.         Subject to Sections 9.12 of the Bridge Loan Agreement, to the fullest extent permitted by
applicable law, the obligations of each of the Guarantors hereunder shall be unconditional and absolute and, without limiting the generality of the foregoing, shall not be released, discharged or otherwise affected by: 

(a)         any extension, renewal, settlement, indulgence, compromise, waiver or
release of or with respect to the Guaranteed Obligations or any part thereof or any agreement relating thereto, or with respect to any obligation of any other guarantor of any of the Guaranteed Obli-


  
 -4- 








 
gations, whether (in any such case) by operation of law or otherwise, or any failure or omission to enforce any right, power or remedy with respect to the Guaranteed Obligations or any part
thereof or any agreement relating thereto, or with respect to any obligation of any other guarantor of any of the Guaranteed Obligations; 

(b)         any modification or amendment of or supplement to the Bridge Loan
Agreement or any other Loan Document, including, without limitation, any such amendment which may increase the amount of, or the interest rates applicable to, any of the Guaranteed Obligations guaranteed hereby; 

(c)         any release, surrender, compromise, settlement, waiver, subordination or
modification, with or without consideration, of any collateral securing the Guaranteed Obligations or any part thereof, any other guaranties with respect to the Guaranteed Obligations or any part thereof, or any other obligation of any person or
entity with respect to the Guaranteed Obligations or any part thereof, or any nonperfection or invalidity of any direct or indirect security for the Guaranteed Obligations; 

(d)         any change in the corporate, partnership, limited liability company or
other existence, structure or ownership of the Borrower or any other guarantor of any of the Guaranteed Obligations, or any insolvency, bankruptcy, reorganization or other similar proceeding affecting the Borrower or any other guarantor of the
Guaranteed Obligations, or any of their respective assets or any resulting release or discharge of any obligation of the Borrower or any other guarantor of any of the Guaranteed Obligations; 

(e)         the existence of any claim, setoff or other rights which the Guarantors
may have at any time against the Borrower, any other guarantor of any of the Guaranteed Obligations, the Administrative Agent, any Guaranteed Creditor or any other Person, whether in connection herewith or in connection with any unrelated
transactions, provided that nothing herein shall prevent the assertion of any such claim by separate suit or compulsory counterclaim; 

(f)         the enforceability or validity of the Guaranteed Obligations or any part
thereof or the genuineness, enforceability or validity of any agreement relating thereto or with respect to any collateral securing the Guaranteed Obligations or any part thereof, or any other invalidity or unenforceability relating to or against
the Borrower or any other guarantor of any of the Guaranteed Obligations, for any reason related to the Bridge Loan Agreement or any provision of applicable law, decree, order or regulation purporting to prohibit the payment by the Borrower or any
other guarantor of the Guaranteed Obligation or otherwise affecting any term any of the Guaranteed Obligations; 

(g)         the failure of the Administrative Agent or the Collateral Agent to take
any steps to perfect and maintain any security interest in, or to preserve any rights to, any security or collateral for the Guaranteed Obligations, if any: 

(h)         the election by, or on behalf of, any one or more of the Guaranteed
Creditors, in any proceeding instituted under Chapter 11 of Title 11 of the United States Code (11 U.S.C. 101 et seq.) (or any successor statute, the “Bankruptcy Code”), of the application of Section 1111(b)(2) of the
Bankruptcy Code; 
 (i)         any borrowing or grant of a security interest by
the Borrower, as debtor-in-possession, under Section 364 of the Bankruptcy Code; 

  
 -5- 








 (j)         the disallowance, under
Section 502 of the Bankruptcy Code, of all or any portion of the claims of the Guaranteed Creditors or the Administrative Agent for repayment of all or any part of the Guaranteed Obligations; 

(k)         the failure of any other guarantor to sign or become party to this
Guaranty or any amendment, change, or reaffirmation hereof; or 
 (l)         any
other act or omission to act or delay of any kind by the Borrower, any other guarantor of the Guaranteed Obligations, the Administrative Agent, any Guaranteed Creditor or any other Person or any other circumstance whatsoever (other than payment in
full of the Obligations) which might, but for the provisions of this Section 9, constitute a legal or equitable discharge of any Guarantor’s obligations hereunder or otherwise reduce, release, prejudice or extinguish its liability under
this Guaranty. 
 10.         In the event the Guaranteed Creditors shall at any time in their
discretion permit a substitution of Guarantors hereunder, a party shall wish to become Guarantor hereunder or a party is required to become a Guarantor hereunder pursuant to Section 4.4 of the Bridge Loan Agreement, such substituted or
additional Guarantor shall, upon executing an agreement in the form attached hereto as Exhibit A, become a party hereto and be bound by all the terms and conditions hereof to the same extent as though such Guarantor had originally
executed this Guaranty and in the case of a substitution, in lieu of the Guarantor being replaced. No such substitution shall be effective absent the written consent delivered in accordance with the terms of the Bridge Loan Agreement, nor shall it
in any manner affect the obligations of the other Guarantors hereunder. 
 11.        
  (a)         To the fullest extent permitted by applicable law, each of the Guarantors irrevocably waives acceptance hereof, presentment, demand or action on delinquency, protest and any notice not
provided for herein or under the other Loan Documents, as well as any requirement that at any time any action be taken by any Person against the Borrower, any other guarantor of the Guaranteed Obligations, or any other Person. 

(b)         Notwithstanding anything herein to the contrary, each of the Guarantors hereby
absolutely, unconditionally, knowingly, and expressly waives, to the fullest extent permitted by applicable law: 

(i)           any right it may have to revoke this Guaranty as to future
Indebtedness or notice of acceptance hereof; 
 (ii)        
  (1) notice of acceptance hereof; (2) notice of any Loans or other financial accommodations made or extended under the Loan Documents or the creation or existence of any Guaranteed Obligations; (3) notice of the amount of
the Guaranteed Obligations, subject, however, to each Guarantor’s right to make inquiry of the Administrative Agent and the Guaranteed Creditors to ascertain the amount of the Guaranteed Obligations at any reasonable time; (4) notice of
any adverse change in the financial condition of the Borrower or of any other fact that might increase such Guarantor’s risk hereunder; (5) notice of presentment for payment, demand, protest, and notice thereof as to any instruments among
the Loan Documents; (6) notice of any Default or Event of Default; and (7) all other notices (except if such notice is specifically required to be given to such Guarantor hereunder or under the Loan Documents) and demands to which each
Guarantor might otherwise be entitled; 
 (iii)         its right, if any, to
require the Collateral Agent, the Administrative Agent and the other Guaranteed Creditors to institute suit against, or to exhaust any rights and remedies which 

  
 -6- 








 
the Collateral Agent, the Administrative Agent and the other Guaranteed Creditors has or may have against, the other Guarantors or any third party, or against any Collateral provided by the other
Guarantors, or any third party; and each Guarantor further waives any defense arising by reason of any disability or other defense (other than a defense of payment or performance or the defense that the Termination Date has occurred) of the other
Guarantors or by reason of the cessation from any cause whatsoever of the liability of the other Guarantors in respect thereof; 

(iv)         (a)         any rights to assert
against the Administrative Agent and the other Guaranteed Creditors any defense (legal or equitable), set-off, counterclaim, or claim which such Guarantor may now or at any time hereafter have against the other Guarantors or any other party liable
to the Administrative Agent and the other Guaranteed Creditors (other than a defense of payment or performance or the defense that the Termination Date has occurred); (b) any defense, set-off, counterclaim, or claim, of any kind or nature,
arising directly or indirectly from the present or future lack of perfection, sufficiency, validity, or enforceability of the Guaranteed Obligations or any security therefor; (c) any defense (other than a defense of payment or performance or
the defense that the Termination Date has occurred) such Guarantor has to performance hereunder, and any right such Guarantor has to be exonerated, arising by reason of: the impairment or suspension of the Administrative Agent’s and the other
Guaranteed Creditors’ rights or remedies against the other Guarantors; the alteration by the Administrative Agent and the other Guaranteed Creditors of the Guaranteed Obligations; any discharge of the other Guarantor’s obligations to the
Administrative Agent and the other Guaranteed Creditors by operation of law as a result of the Administrative Agent’s and the other Guaranteed Creditors’ intervention or omission; or the acceptance by the Administrative Agent and the other
Guaranteed Creditors of anything in partial satisfaction of the Guaranteed Obligations; (d) [reserved]; and (e) without limiting the generality of the foregoing, any other defense of waiver, release, discharge in bankruptcy, res judicata,
statue of frauds, anti-deficiency statute, incapacity, minority, usury, illegality or unenforceability which may be available to the Borrower or any other person liable in respect of any of the Guaranteed Obligations; and 

(v)         any defense arising by reason of or deriving from (a) any claim or
defense based upon an election of remedies by the Administrative Agent and the other Guaranteed Creditors; or (b) any election by the Administrative Agent and the other Guaranteed Creditors under the Bankruptcy Code, to limit the amount of, or
any collateral securing, its claim against the Guarantors. 
 (c)         Subject to the last
sentence of Section 2 above, the Guarantors agree that the Guarantors shall be and remain jointly and severally liable for any deficiency remaining after foreclosure or other realization on any lien or security interest securing the Guaranteed
Obligations, whether or not the liability of the Borrower or any other obligor for such deficiency is discharged pursuant to statute or judicial decision. 

12.         No failure or delay by the Administrative Agent or any Guaranteed Creditor in exercising
any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise of any other right, power or privilege. The rights and remedies provided in this
Guaranty, the Bridge Loan Agreement and the other Loan Documents shall be cumulative and not exclusive of any rights or remedies provided by law. 

13.         If any payment applied by the Guaranteed Creditors to the Guaranteed Obligations is
thereafter set aside, recovered, rescinded or required to be returned for any reason (including, without limitation, the bankruptcy, insolvency or reorganization of the Borrower or any other obligor), the Guaranteed Obligations to which such payment
was applied shall for the purposes of this Guaranty be 

  
 -7- 








 
deemed to have continued in existence, notwithstanding such application, and this Guaranty shall be enforceable as to such of the Guaranteed Obligations as fully as if such application had never
been made. 
 14.         Each Guarantor represents and warrants to the Guaranteed Creditors that
as of the date hereof: 
   (a)         (i) Such Guarantor is duly
organized, validly existing and in good standing under the laws of the jurisdiction of its organization, except to the extent the failure of any Guarantor to be in existence and good standing would not reasonably be expected to have a Material
Adverse Effect, (ii) has the power and authority to own its property and to transact the business in which it is engaged and proposes to engage, except where the failure to do so would not reasonably be expected to have a Material Adverse
Effect, and (iii) is duly qualified and in good standing in each jurisdiction where the ownership, leasing or operation of property or the conduct of its business requires such qualification, except, in each case, under this clause
(iii) where the same could not reasonably be expected to have, either individually or in the aggregate, a Material Adverse Effect. 

  (b)         Such Guarantor has the power and authority to enter into this
Guaranty, to guarantee the Guaranteed Obligations and to perform all of its obligations under this Guaranty. 

  (c)         The Guaranty has been duly authorized, executed, and delivered
by such Guarantor and constitutes a valid and binding obligation of such Guarantor enforceable against it in accordance with its terms, except as enforceability may be limited by bankruptcy, insolvency, fraudulent conveyance or similar laws
affecting creditors’ rights generally and general principles of equity (regardless of whether the application of such principles is considered in a proceeding in equity or at law). 

  (d)         This Guaranty does not, nor does the performance or observance
by such Guarantor of any of the matters and things herein provided for, (i) violate any provision of law or any judgment, injunction, order or decree binding upon such Guarantor, (ii) contravene or constitute a default under any provision
of the organizational documents (e.g., charter, articles of incorporation or by-laws, articles of association or operating agreement, partnership agreement or other similar document) of such Guarantor,
(iii) contravene or constitute a default under any covenant, indenture or agreement of or affecting such Guarantor or any of its Property or (iv) result in the creation or imposition of any Lien on any Property of such Guarantor other than
the Liens granted to the Administrative Agent pursuant to any Loan Document and Permitted Liens, except with respect to clauses (i), (iii) and (iv), to the extent, individually or in the aggregate, that such violation, contravention, breach,
conflict, default or creation or imposition of any Lien could not reasonably be expected to result in a Material Adverse Effect. 

  (e)         From and after the date of execution of this Agreement or any
agreement in the form attached hereto as Exhibit A by any Guarantor and continuing until the Termination Date or until such Guarantor is earlier released from its obligations hereunder in accordance with Section 6 hereof, such Guarantor
agrees to perform and observe, and cause each of its Subsidiaries to perform and observe, all of the terms, covenants and agreements set forth in Article VI of the Bridge Loan Agreement on its or their part to be performed or observed or that the
Borrower has agreed to cause such Guarantor or such Subsidiaries to perform or observe. 

15.         The liability of the Guarantors under this Guaranty is in addition to and shall be
cumulative with all other liabilities of the Guarantors after the date hereof to the Guaranteed Creditors as 

  
 -8- 








 
a Guarantor of the Guaranteed Obligations, without any limitation as to amount, unless the instrument or agreement evidencing or creating such other liability specifically provides to the
contrary. 
 16.         Any provision of this Guaranty which is unenforceable in any jurisdiction
shall, as to such jurisdiction, be ineffective to the extent of such unenforceability without invalidating the remaining provisions hereof or affecting the validity or enforceability of such provision in any other jurisdiction. All rights, remedies
and powers provided in this Guaranty may be exercised only to the extent that the exercise thereof does not violate any applicable mandatory provisions of law, and all the provisions of this Guaranty are intended to be subject to all applicable
mandatory provisions of law which may be controlling and to be limited to the extent necessary so that they will not render this Guaranty invalid or unenforceable. 

17.         Any demand for payment on this Guaranty or any other notice required or desired to
be given hereunder to any Guarantor shall comply with Section 10.8 of the Bridge Loan Agreement; provided that, the address information for each Guarantor shall be its address or facsimile number set forth below, or such other address or
facsimile number as such party may hereafter specify by notice to the Administrative Agent given by courier, United States certified or registered mail, by facsimile, by email transmission or by other telecommunication device capable of creating
written record of such notice and its receipt. Each such notice, request or other communication shall be effective (i) if given by facsimile, when such facsimile is transmitted to the facsimile number specified in this Section 17 and a
confirmation of such telecopy has been received by the sender, (ii) if given by mail, five days after such communication is deposited in the mail, certified or registered with return receipt requested, addressed as aforesaid, (iii) if
by email, when delivered (all such notices and communications sent by email shall be deemed delivered upon the sender’s receipt of an acknowledgement from the intended recipient (such as by the “return receipt requested” function, as
available, return email or other written acknowledgement)), or (iv) if given by any other means, when delivered at the addresses specified in this Section.

 19.         THIS GUARANTY AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES
