(the “Subscriber”) 60,470 shares of the Company’s Class A common stock, par value $0.0001 per share (the “Class A Common Stock”), in a private placement transaction (such transaction, the “Subscription”).

NOW, THEREFORE, the Subscriber, the Company and Voyager agree as follows (this “Agreement”):

1.    Subscription.Subject to the terms and conditions hereof, the Subscriber hereby agrees to subscribe for and purchase, and the Company hereby agrees to issue and sell to the Subscriber, 60,470 shares of Class A Common Stock (the “Shares”) for an aggregate purchase price of $604,700.00 (the “Subscription Amount”). Notwithstanding anything in this Agreement to the contrary but subject to the following proviso, in the event the Closing occurs and the Subscription Amount is funded in accordance with Section 2 below, the Subscriber shall have no liability for any claims or losses arising out of this Agreement;provided, in the event the Subscription Amount is not funded in accordance with Section 2 below, the Subscriber’s liability for any claims or losses arising out of this Agreement shall be limited to the Subscription Amount.

2.    Closing.The closing of the sale of Shares (the “Closing”) contemplated under this Agreement shall occur on the date of, and immediately prior to, the consummation of the Transaction. Upon (i) satisfaction of the conditions set forth in Section 3 below and (ii) written notice from (or on behalf of) the Company to the Subscriber (the “Closing Notice”) that the Company reasonably expects all conditions to the closing of the Transaction to be satisfied on a date that is not less than two (2) Business Days from the date of the Closing Notice, the Subscriber shall deliver to the Company on or prior to the closing date specified in the Closing Notice (the “Expected Closing Date”; the date on which the Closing actually occurs, the “Closing Date”) the Subscription Amount by wire transfer of United States dollars in immediately available funds to the account specified by the Company in the Closing Notice

1

against delivery of the Shares in certificated or book entry form to the Subscriber or to a custodian designated by the Subscriber, as applicable. In the event the closing of the Transaction does not occur within ten (10) Business Days of the Expected Closing Date, the Company shall promptly (but no later than ten (10) Business Days thereafter) return the Subscription Amount to the Subscriber by wire transfer of United States dollars in immediately available funds to the account specified by the Subscriber, and any book entries shall be deemed cancelled. Notwithstanding such return or cancellation, (A) a failure to close on the Expected Closing Date shall not, by itself, be deemed to be a failure of any of the conditions to Closing set forth in Section 3 of this Agreement to be satisfied or waived on or prior to the Closing, and (B) the Subscriber shall still be obligated to consummate the Closing upon (I) satisfaction of the conditions set forth in Section 3 below and (II) the Company’s delivery to the Subscriber of a new Closing Notice.

3.    Closing Conditions.

(a)    The obligation of the Subscriber, on the one hand, and the Company, on the other hand, to effect the Closing is subject to the satisfaction or written waiver by the Subscriber and the Company prior to the Closing of the following conditions:

(i)    there shall not have been enacted or promulgated any order, judgment, injunction, decree, writ, stipulation, determination or award, in each case, entered by or with any court or governmental agency or body, domestic or foreign, nor any statute, rule or regulation, in either case, enjoining or prohibiting the consummation of the Subscription; and

(ii)    the Transaction as set forth in the Transaction Agreement shall have been consummated substantially concurrently with the Closing.

(b)    The obligation of the Subscriber to effect the Closing is also subject to the satisfaction or written waiver by the Subscriber prior to the Closing of the following conditions:

(ii)    no amendment or modification of the Transaction Agreement (as the same exists on the date hereof as provided to the Subscriber) shall have occurred that would reasonably be expected to materially and adversely affect the economic benefits that the Subscriber would reasonably expect to receive under this Agreement, unless the Subscriber has consented in writing to such amendment or modification.

(b)    The Subscriber understands that the Shares are being offered in a transaction not involving any public offering within the meaning of the Securities Act and that the Shares have not been registered under the Securities Act. The Subscriber understands that the Shares may not be resold, transferred, pledged or otherwise disposed of by the Subscriber absent an effective registration statement under the Securities Act except (i) to the Company or a subsidiary thereof, (ii) tonon-U.S. persons pursuant to offers and sales that occur outside the United States within the meaning of Regulation S under the Securities Act or (iii) pursuant to another applicable exemption from the registration requirements of the Securities Act, and in each of cases (i) and

(iii), in accordance with any applicable securities laws of the states and other jurisdictions of the United States, and that any certificates or book entry account representing the Shares shall contain a legend to such effect substantially consistent with the legend set forth in Section 7(b). The Subscriber acknowledges that the Shares will not be eligible for resale pursuant to Rule 144A. The Subscriber understands and agrees that the Shares will be subject to transfer restrictions and, as a result of these transfer restrictions, the Subscriber may not be able to readily resell the Shares and may be required to bear the financial risk of an investment in the Shares for an indefinite period of time.

Without limiting the generality of the foregoing, the Subscriber acknowledges that it has reviewed (i) the Company’s and APX Group Holdings, Inc.’s filings with the Securities and Exchange Commission (“SEC”); and (ii) certain business and legal due diligence materials with respect to Voyager provided to the Subscriber by the Company. The Subscriber represents and agrees that the Subscriber and the Subscriber’s professional advisor(s), if any, have had the full opportunity to ask such questions, receive such answers and obtain such information as the Subscriber and the Subscriber’s professional advisor(s), if any, have deemed necessary to make an investment decision with respect to the Shares.

(e)    The Subscriber became aware of this offering of the Shares solely by means of direct contact between the Subscriber and the Company or a representative of the Company, and the Shares were offered to the Subscriber solely by direct contact between the Subscriber and the Company or a representative of the Company. The Subscriber did not become aware of this offering of the Shares, nor were the Shares offered to the Subscriber, by any other means. The Subscriber acknowledges that the Company represents and warrants that the Shares (i) were not offered by any form of general solicitation or general advertising and (ii) are not being offered in a manner involving a public offering under, or in a distribution in violation of, the Securities Act, or any state securities laws.

(f)    The Subscriber acknowledges that it is aware that there are substantial risks incident to the purchase and ownership of the Shares, including those set forth in the Company’s and APX Group Holdings, Inc.’s filings with the SEC. The Subscriber has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of an investment in the Shares, and the Subscriber has sought such accounting, legal and tax advice as the Subscriber has considered necessary to make an informed investment decision.

(g)    Alone, or together with any professional advisor(s), the Subscriber has adequately analyzed and fully considered the risks of an investment in the Shares and determined that the Shares are a suitable investment for the Subscriber and that the Subscriber is able at this time and

5

in the foreseeable future to bear the economic risk of a total loss of the Subscriber’s investment in the Company. The Subscriber acknowledges specifically that a possibility of total loss exists.

(h)    In making its decision to purchase the Shares, the Subscriber has relied solely upon independent investigation made by the Subscriber. Without limiting the generality of the foregoing, the Subscriber has not relied on any statements or other information provided by anyone other than the Company concerning the Company or the Shares or the offer and sale of the Shares.

(i)    The Subscriber understands and agrees that no federal or state agency has passed upon or endorsed the merits of the offering of the Shares or made any findings or determination as to the fairness of this investment.

(j)    The Subscriber has been duly formed or incorporated and is validly existing in good standing under the laws of its jurisdiction of incorporation or formation.

(k)    The execution, delivery and performance by the Subscriber of this Agreement are within the powers of the Subscriber, have been duly authorized and will not constitute or result in a breach or default under or conflict with any order, ruling or regulation of any court or other tribunal or of any governmental commission or agency, or any agreement or other undertaking, to which the Subscriber is a party or by which the Subscriber is bound, and will not violate any provisions of the Subscriber’s charter documents, including, without limitation, its incorporation or formation papers, bylaws, indenture of trust or partnership or operating agreement, as may be applicable, or any other agreements to which it is party or to which its assets or business are subject. The signature of the Subscriber on this Agreement is genuine, and the signatory has been duly authorized to execute the same, and this Agreement constitutes a legal, valid and binding obligation of the Subscriber, enforceable against the Subscriber in accordance with its terms, subject to applicable bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and similar laws affecting creditors’ rights generally and subject, as to enforceability, to general principles of equity.

(l)    Neither the due diligence investigation conducted by the Subscriber in connection with making its decision to acquire the Shares nor any representations and warranties made by the Subscriber herein shall modify, amend or affect the Subscriber’s right to rely on the truth, accuracy and completeness of the Company’s representations and warranties contained herein.

(m)    The Subscriber is not (i) a person or entity named on the List of Specially Designated Nationals and Blocked Persons administered by the U.S. Treasury Department’s Office of Foreign Assets Control (“OFAC”) or in any Executive Order issued by the President of the United States and administered by OFAC (“OFAC List”), or a person or entity prohibited by any OFAC sanctions program, (ii) a Designated National as defined in the Cuban Assets Control Regulations, 31 C.F.R.

(the “BSA”), as amended by the USA PATRIOT Act of 2001 (the “PATRIOT Act”), and its implementing regulations (collectively,

6

the “BSA/PATRIOT Act”), the Subscriber maintains policies and procedures reasonably designed to comply with applicable obligations under the BSA/PATRIOT Act. To the extent required by law, it maintains policies and procedures reasonably designed for the screening of its investors against the OFAC sanctions programs, including the OFAC List. To the extent required by law, it maintains policies and procedures reasonably designed to ensure that the funds held by the Subscriber and used to purchase the Shares were legally derived.

(n)    Subject to the satisfaction of the terms and conditions of this Agreement, the Subscriber will have sufficient funds to pay the Subscription Amount pursuant to Section 2 at the Closing.

(o)    The Subscriber acknowledges and agrees that this Agreement is being entered into in order to induce Voyager to enter into the Transaction Agreement and that Voyager is a third-party beneficiary of the Subscriber’s commitment hereunder.

(b)    Each register and book entry for the Securities shall contain a notation, and each certificate (if any) evidencing the Securities shall be stamped or otherwise imprinted with a legend, in substantially the following form:

COPIES OF SUCH AGREEMENT MAY BE OBTAINED UPON WRITTEN REQUEST TO THE SECRETARY OF THE COMPANY.

(c)    If the Securities are eligible to be sold without restriction under, and without the Company being in compliance with the current public information requirements of, Rule 144 under the Securities Act, then at the Subscriber’s request, the Company will cause the Company’s transfer agent to remove the legend set forth in Section 7(b). In connection therewith, if required by the Company’s transfer agent, the Company will promptly cause an opinion of counsel to be delivered to and maintained with its transfer agent, together with any other authorizations, certificates and directions required by the transfer agent that authorize and direct the transfer agent to issue such Securities without any such legend.

8

assign any such rights, interests or obligations assigned to it;provided,further, that the aggregate amount of the Subscription Amount assigned to all Eligible Participants may not exceed an amount equal to the Subscription Amount multiplied by the percentage of the beneficial ownership of Voyager owned by all Eligible Participants (for the avoidance of doubt, the Eligible Participants’ beneficial ownership of Voyager shall be determined by combining the Eligible Participants’ direct ownership in Voyager and the Eligible Participants’ indirect ownership in Voyager through 313 (as determined based on their pro rata ownership of 313)).

(f)    This Agreement may not be modified or waived (i) except by an instrument in writing, signed by the party against whom enforcement of such modification or waiver is sought and (ii) without the prior written consent of Voyager.

(g)    This Agreement constitutes the entire agreement, and supersedes all other prior agreements, understandings, representations and warranties, both written and oral, among the parties, with respect to the subject matter hereof. This Agreement shall not confer any rights or remedies upon any person other than the parties hereto, and their respective successors and assigns;provided, that, subject to the terms and conditions of this Agreement and the Transaction Agreement, Voyager shall have the right, as a third party beneficiary of this Agreement, to obtain specific performance of the Subscriber’s obligation to cause the Subscription Amount to be funded when due hereunder (including, to the extent necessary to cause such funding, to cause the Subscriber to use reasonable best efforts to enforce contractual commitments available to the Subscriber), but solely to the extent the Company has the right hereunder to enforce such obligation pursuant to the terms, and subject to the conditions, hereof and solely to the extent required to give effect to a grant of specific performance to Voyager under and in accordance with the terms and conditions of the Transaction Agreement (as in effect on the date hereof), and for no other purpose, which right of Voyager as third party beneficiary shall be the sole and exclusive direct or indirect right and remedy (whether at law or in equity) available to Voyager

9

and its security holders and affiliates (or available to any Person claiming by, through, or on behalf or for the benefit of any of them) against the Subscriber or any of its direct or indirect equityholders, management companies, affiliates, agents, attorneys, or representatives, and any financial advisor or lender or any affiliate of any of the foregoing, with respect to any claim (whether sounding in contract or tort, under statute or otherwise) arising under or related to the Transaction Agreement or this Agreement or the transactions contemplated hereby or thereby or related negotiations, including without limitation in connection with any beach or alleged breach by the Company of any obligation under or related to the Transaction Agreement (whether or not any such breach or alleged breach is caused by the Subscriber’s breach of its obligations under this Agreement) and any breach or alleged breach by the Subscriber of any obligation under or related to this Agreement.

(i)    If any provision of this Agreement shall be invalid, illegal or unenforceable, the validity, legality or enforceability of the remaining provisions of this Agreement shall not in any way be affected or impaired thereby and shall continue in full force and effect.

(j)    This Agreement may be executed in one or more counterparts (including by facsimile or electronic mail or in .pdf) and by different parties in separate counterparts, with the same effect as if all parties hereto had signed the same document. All counterparts so executed and delivered shall be construed together and shall constitute one and the same agreement.

(k)    The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, this being in addition to any other remedy to which such party is entitled at law, in equity, in contract, in tort or otherwise.

(l)    THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF DELAWARE, WITHOUT REGARD TO THE PRINCIPLES OF CONFLICTS OF LAWS THAT WOULD OTHERWISE REQUIRE THE APPLICATION OF THE LAW OF ANY OTHER STATE. EACH PARTY HERETO HEREBY WAIVES ANY RIGHT TO A JURY TRIAL IN CONNECTION WITH ANY LITIGATION PURSUANT TO THIS AGREEMENT AND THE TRANSACTIONS CONTEMPLATED HEREBY.

(m)    Each party hereto hereby, and any person asserting rights as a third party beneficiary hereunder may do so only if he, she or it, irrevocably agrees that any claims shall be brought only to the exclusive jurisdiction of the courts of the State of Delaware located in New Castle County or, if such courts decline to exercise jurisdiction, any federal or state court located

10

in New York County, New York, and each party hereby consents to the jurisdiction of such courts (and of the appropriate appellate courts therefrom) in any such suit, action or proceeding and irrevocably waives, to the fullest extent permitted by law, any objection that it may now or hereafter have to the laying of the venue of any such suit, action or proceeding in any such court or that any such suit, action or proceeding that is brought in any such court has been brought in an inconvenient forum. During the period a claim that is filed in accordance with this Section 11(m) is pending before a court, all actions, suits or proceedings with respect to such claim or any other claim, including any counterclaim, cross-claim or interpleader, shall be subject to the exclusive jurisdiction of such court. Each party and any person asserting rights as a third party beneficiary may do so only if he, she or it hereby waives, and shall not assert as a defense in any claim, that (a) such party is not personally subject to the jurisdiction of the above named courts for any reason, (b) such action, suit or proceeding may not be brought or is not maintainable in such court, (c) such party’s property is exempt or immune from execution, (d) such action, suit or proceeding is brought in an inconvenient forum, or (e) the venue of such action, suit or proceeding is improper. A final judgment in any action, suit or proceeding described in this Section 11(m) following the expiration of any period permitted for appeal and subject to any stay during appeal shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.

12.    Non-Reliance and Exculpation.The Subscriber acknowledges that it is not relying upon, and has not relied upon, any statement, representation or warranty made by any person, firm or corporation (including, without limitation, Voyager, any of its affiliates or any of its or their control persons, officers, directors and employees), other than the statements, representations and warranties contained in this Agreement, in making its investment or decision to invest in the Company. The Subscriber agrees that neither (i) any other purchaser pursuant to this Agreement or any other agreement related to the private placement of the Shares (including the respective controlling persons, officers, directors, partners, agents, or employees of any such purchaser) nor (ii) Voyager, its affiliates or any of its or their affiliates’ control persons, officers, directors or employees, shall be liable to any other purchaser pursuant to this Agreement or any other Agreement related to the private placement of the Shares for any action heretofore or hereafter taken or omitted to be taken by any of them in connection with the purchase of the Shares.
