 (6) The Company meets the requirements for use of Form S-3 under the Securities
Act. The Registration Statement, which covers the Offered Shares, including a form of prospectus and such amendments or supplements to such Registration Statement as may have been required prior to the date of this Agreement, has been prepared by
the Company under the provisions of the Securities Act, has been filed with the Commission, has become effective and filed with the Commission and incorporates by reference documents which the Company has filed in accordance with the provisions of
the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The Company has prepared a Prospectus Supplement to the prospectus included in the Registration Statement referred to above, setting forth the terms of the
offering and sale of the Offered Shares and additional information concerning the Company and its business and will promptly file the Prospectus Supplement with the Commission pursuant to Rule 424(b). No stop order suspending the effectiveness of
the Registration Statement or any post-effective amendment thereto, or any part thereof, has been issued and served on the Company, and no proceedings for that purpose are pending or, to the knowledge of the Company, threatened by the Commission.
The form of prospectus included in the Registration Statement as of the date hereof, as amended or supplemented from time to time (including the Prospectus Supplement), is referred to herein as the “Prospectus.” Any reference herein
to the Registration Statement, the Prospectus or any amendment or supplement thereto shall be deemed to refer to and include the documents incorporated (or deemed to be incorporated) by reference therein, and any reference herein to the terms

and the Prospectus and any amendment or supplement thereto, on the date of filing thereof with the Commission and at the date hereof and the date of the Closing, did or will in all material respects comply with all applicable provisions of the
Securities Act and the Exchange Act. Each part of the Registration Statement, when such part became or becomes effective, did not or will not contain any untrue statement of a material fact or omit to state a material fact required to be stated
therein or necessary in order to make the statements therein not misleading. The Prospectus and any amendment or supplement thereto, on the date of filing thereof with the Commission, did not or will not contain any untrue statement of a material
fact or omit to state a material fact necessary to make the statements 

  
 5 

 
therein, in the light of the circumstances under which they were made, not misleading. The foregoing representations and warranties in this Section 4(b)(6) do not apply to any
statements or omissions made in reliance on and in conformity with information relating to the Investors furnished in writing to the Company by the Investors specifically for inclusion in the Registration Statement or Prospectus or any amendment or
supplement thereto. 
 (7) The audited consolidated balance sheets of the Company as at June 30, 2012 and June 30
2011, and the related consolidated statements of income and of cash flows for the fiscal years ended on such dates, reported on by and accompanied by an audit report from KPMG LLP, present fairly in all material respects the consolidated financial
condition of the Company as at such date, and the consolidated results of its operations and its consolidated cash flows for the respective fiscal years then ended. The unaudited condensed consolidated balance sheet of the Company as at
March 31, 2013, and the related unaudited condensed consolidated statements of operations and cash flows for such period, present fairly the consolidated financial condition of the Company as at such date, and the consolidated results of its
operations and its consolidated cash flows for the such period then ended (subject to normal year end audit adjustments). All such financial statements, including the related schedules and notes thereto, have been prepared in accordance with United
States generally accepted accounting principles (“GAAP”) applied consistently throughout the periods involved (except as approved by the aforementioned firm of accountants and disclosed therein). 

(8) Since March 31, 2013, there has been no development or event that has had or could reasonably be expected to have a Material
Adverse Effect. Since the date of the Company’s most recent audited financial statements contained in a Form 10-K, except as disclosed in the SEC Documents filed subsequent thereto, neither the Company nor any of its Subsidiaries has
(i) declared or paid any dividends, (ii) sold any assets, individually or in the aggregate, outside of the ordinary course of business or (iii) made any material capital expenditures, individually or in the aggregate. Neither the
Company nor any of its Subsidiaries has taken any steps to seek protection pursuant to any law or statute relating to bankruptcy, insolvency, reorganization, receivership, liquidation or winding up, nor does the Company or any Subsidiary have any
knowledge or reason to believe that any of their respective creditors intend to initiate involuntary bankruptcy proceedings or any actual knowledge of any fact which would reasonably lead a creditor to do so. 

(9) There is no pending or, to the Company’s knowledge, threatened action, suit or proceeding, nor any injunction, writ,
restraining order or other order of any nature against or affecting any the Company or any of its Subsidiaries, its officers or directors, or the property of the Company or any of its Subsidiaries, in any court or tribunal, or before any arbitrator
of any kind or before or by any Governmental Authority (i) asserting the invalidity of this Agreement or the other Transaction Documents, (ii) seeking to prevent the consummation of any of the transactions contemplated hereby or thereby,
(iii) seeking any determination or ruling that might materially and adversely affect (A) the performance by the Company of this Agreement or the other Transaction Documents or (B) the validity or enforceability of this Agreement or
the other Transaction Documents or (iv) asserting a claim for payment of money adverse to the Company or any of its Subsidiaries or the conduct of its or their business other than the litigation disclosed in the Company’s filings posted on
the SEC Edgar website, except in each, as would not in the aggregate reasonably be expected to have a Material Adverse Effect. “Governmental Authority” means the government of the United States or any other nation, or of any
political subdivision thereof, whether state or local, and any agency, authority, instrumentality, regulatory body, court, central bank or other entity exercising executive, legislative, judicial, taxing, regulatory or administrative powers or
functions of or pertaining to government.

interest in, all of its property (other than intellectual property) that is essential to its business as conducted on the date hereof. For the avoidance of doubt, it is understood and agreed that the Company and each of its Subsidiaries may, as part
of its respective business, grant licenses to third parties to use intellectual property owned or developed by the Company and its Subsidiaries. 
 (11) The Company and each of its Subsidiaries has filed or caused to be filed all Federal, state and other material tax returns that are required to be filed and has paid all taxes shown to be due and
payable on said returns or on any assessments made against it or any of its property and all other taxes, fees or other charges imposed on it or any of its property by any Governmental Authority (other than any the amount or validity of which are
currently being contested in good faith by appropriate proceedings and with respect to which reserves in conformity with GAAP have been provided on the books of the Company); no tax lien has been filed, and, to the knowledge of the Company, no claim
is being asserted, with respect to any such tax, fee or other charge, other than as would not reasonably be expected to have a Material Adverse Effect. 
 (12) There are no holders of securities of the Company having preemptive rights to purchase Common Stock. There are no holders or beneficial owners of securities of the Company having rights to
registration thereof whose securities have not been previously registered or who have not waived such rights with respect to the registration of the Company’s securities on the Registration Statement. 

(13) The Company is not an “investment company”, or a company “controlled” by an “investment company”,
within the meaning of the Investment Company Act of 1940, as amended. 
 (14) The Company and each Subsidiary is in compliance
with all applicable requirements of the Sarbanes-Oxley Act of 2002 that are effective as of the date hereof, and all applicable rules and regulations promulgated by the Commission thereunder that are effective as of the date hereof.

each of the SEC Documents complied in all material respects with the requirements of the Securities Act or the Exchange Act and the rules and regulations of the Commission promulgated thereunder applicable to such SEC Document. The Company has filed
with the Commission all “material contracts” (as such term is defined in Item 601(b)(10) of Regulation S-K under the Exchange Act) that are required to be filed as exhibits to the SEC Documents and there are no contracts or other
documents that are required under the Exchange Act to be described in the SEC Documents that are not so described. No SEC Document, when filed, or, in the case of any SEC Document amended or superseded prior to the date of this Agreement, then on
the date of such amending or superseding filing, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading. Any SEC Document filed with the Commission prior to Closing, when filed, will not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they are made, not misleading.

Subsidiaries.

inapplicable any control share acquisition, interested stockholder, business combination, poison pill (including any distribution under a rights agreement) or other similar anti-takeover provision under the Certificate of Incorporation, By-Laws or
other organizational documents of the Company or the laws of the jurisdiction of its incorporation or otherwise that can be waived by approval of the board of directors and which is or could become applicable to any Investor as a result of the
transactions contemplated by this Agreement or the Backstop Purchase Agreement, including, without limitation, the Company’s issuance of the Offered Shares and any Investor’s ownership of the Offered Shares. The Company and its board of
directors have taken all necessary action, if any, in order to render inapplicable any stockholder rights plan or similar arrangement relating to accumulations of beneficial ownership of shares of Common Stock or a change in control of the Company
or any of its Subsidiaries. 
 (18) Except as would not reasonably be expected, individually or in the aggregate, to have a
Material Adverse Effect: (i) each employee benefit plan, within the meaning of Section 3(3) of Employee Retirement Income Security Act of 1974, as amended from time to time (“ERISA”), for which the Company or any ERISA
Affiliate has any liability (each, a “Plan”) has been maintained in all material respects in compliance with its terms and the requirements of any applicable statutes, orders, rules and regulations, including but not limited to
ERISA and the Code; (ii) no prohibited transaction, within the meaning of Section 406 of ERISA or Section 4975 of the Internal Revenue Code of 1986, as amended (the “Code”), has occurred with respect to any Plan
excluding transactions effected pursuant to a statutory or administrative exemption; (iii) for each Plan that is subject to the funding rules of Section 412 of the Code or Section 302 of ERISA, no failure to satisfy the minimum
funding standard of Section 412 of the Code or Section 302 of ERISA, whether or not waived, has occurred or is reasonably expected to occur; (iv) with respect to each Plan that is subject to Title IV of ERISA, the fair market value of
the assets of each Plan is no more than $100,000 less than the present value of all benefits accrued under such Plan (determined based on those assumptions used to fund such Plan); (v) no “reportable event” (within the meaning of
Section 4043(c) of ERISA) has occurred or is reasonably expected to occur with respect to any Plan; and (vi) neither the Company nor any ERISA Affiliate has incurred, nor reasonably expects to incur, any liability under Title IV of ERISA
(other than contributions to the Plan or premiums to the Pension Benefit Guaranty Corporation (or any successor), in the ordinary course and without default) in respect of a Plan (including a “multiemployer plan”, within the meaning of
Section 4001(a)(3) of ERISA). “ERISA Affiliate” means any trade or business (whether or not incorporated) that, together with the Company, is treated as a single employer under Section 414 of the Code. 

(19) Except as disclosed in the SEC Documents, none of the officers, directors or employees or affiliates of the Company or any of its
Subsidiaries is presently a party to any transaction with the Company or any of its Subsidiaries (other than for ordinary course services as employees, officers or directors), including any contract, agreement or other arrangement providing for the
furnishing of services to or by, providing for use of property, or otherwise requiring payments to or from any such officer, director or employee or, to the knowledge of the Company or any of its Subsidiaries, any corporation, partnership, trust or
other Person in which any such officer, director or employee or affiliate has a substantial interest or is an employee, officer, director, trustee or partner. 
 (20) Schedule 20 lists all patents and patent applications owned by the Company and its Subsidiaries in its own and their own name on the date hereof (disregarding any de minimus inaccuracies). The
Patents owned by the Company and its Subsidiaries have not been adjudged invalid or unenforceable, in whole or in part, and, except as would not individually or in the aggregate reasonably be expected to have a Material Adverse Effect.

 (21) Assuming the accuracy of the Investors’ representations and warranties set forth
in Section 4(a), neither the Company, nor any of its Affiliates, nor any Person acting on its or 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 cause this offering of the Offered Shares to be integrated with prior offerings by the Company for purposes of any applicable shareholder approval provisions of any market or exchange on which any of the securities of the Company are
listed or designated. 
 (22) The Company acknowledges and agrees that each Investor is acting solely in the capacity of an
arm’s length purchaser with respect to the Transaction Documents and the transactions contemplated hereby and thereby and that no Investor is (i) an officer or director of the Company or any of its Subsidiaries, or (ii) an
“affiliate” (as defined in Rule 144 promulgated under the 1933 Act (or a successor rule thereto) (collectively, “Rule 144”)) of the Company (an “Affiliate”) or any of its Subsidiaries. The Company further
acknowledges that no Investor is acting as a financial advisor or fiduciary of the Company or any of its Subsidiaries (or in any similar capacity) with respect to the Transaction Documents and the transactions contemplated hereby and thereby, and
any advice given by an Investor or any of its representatives or agents in connection with the Transaction Documents and the transactions contemplated hereby and thereby is merely incidental to such Investor’s purchase of the Offered Shares.
The Company further represents to each Investor that the Company’s decision to enter into the Transaction Documents has been based solely on the independent evaluation by the Company and its representatives. The Company has never been a
“shell” company under applicable rules of the SEC. 
 (23) No statement or information contained in this Agreement,
any other Transaction Document or any other document, certificate or statement furnished by or on behalf of the Company to the Investors, or any of them, for use in connection with the transactions contemplated by this Agreement or the other
Transaction Documents, contained as of the date such statement, information, document or certificate was so furnished, any untrue statement of a material fact or omitted to state a material fact necessary to make the statements contained herein or
therein not misleading, when taken together with all statements contained in such documents and the Company’s filings and furnishings with the Commission. There is no fact known to the Company that would reasonably be expected to have a
Material Adverse Effect that has not been expressly disclosed herein, the Company’s filings and furnishings with the Commission, in the other Transaction Documents or in any other documents, certificates and statements furnished to the
Investors for use in connection with the transactions contemplated hereby and by the other Transaction Documents. 
 (24) The
Company confirms that neither it nor, to its knowledge, any other Person acting on its behalf has provided any of the Investors or their agents or counsel with any information that constitutes or could reasonably be expected to constitute material,
non-public information concerning the Company or any of its Subsidiaries, other than the existence of the transactions contemplated by this Agreement, the Transaction Documents, the Backstop Purchase Agreement, the Note Purchase Agreement and the
principal transactions documents related thereto. The Company understands and confirms that each of the Investors will rely on the foregoing representations in effecting transactions in securities of the Company. All disclosure provided to the
Investors regarding the Company and its Subsidiaries, their businesses and the transactions contemplated hereby, including the schedules to this Agreement, furnished by or on behalf of the Company or any of its Subsidiaries is true and correct and
does not contain any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements made therein, in the light of the circumstances under which

  
 9 

 
they were made, not misleading. Each material press release issued by the Company or any of its Subsidiaries during the twelve (12) months preceding the date of this Agreement did not at the
time of release contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they are made, not
misleading. No event or circumstance has occurred or information exists with respect to the Company or any of its Subsidiaries or its or their business, properties, liabilities, prospects, operations (including results thereof) or conditions
(financial or otherwise), which, under applicable law, rule or regulation, requires public disclosure at or before the date hereof or announcement by the Company but which has not been so publicly disclosed. The Company acknowledges and agrees that
no Investor makes or has made any representations or warranties with respect to the transactions contemplated hereby other than those specifically set forth in Section 4(a). 

(25) The Company is solvent and will not become insolvent after giving effect to the transactions contemplated by this Agreement and
each of the other Transaction Documents. 
 (26) Neither the Company nor any of its Subsidiaries has, and, to the knowledge of
the Company, no Person acting on their behalf has, directly or indirectly, (i) taken any action designed to cause or to result in the stabilization or manipulation of the price of any security of the Company or any of its Subsidiaries to
facilitate the sale or resale of any of the Offered Shares, (ii) sold, bid for, purchased, or paid any compensation for soliciting purchases of, any of the Offered Shares, or (iii) paid or agreed to pay to any Person any compensation for
soliciting another to purchase any other securities of the Company or any of its Subsidiaries. 
 (27) The Company shall pay
directly, or reimburse to each Investor, the reasonable and documented out-of-pocket costs and expenses incurred by such Investor (including, without limitation, the reasonable and documented fees and expenses of counsel) in connection with the
entering into and matters related to this Agreement, the Note Purchase Agreement, the Backstop Purchase Agreement, and the other transactions contemplated herein and therein; provided that such reimbursable expenses in connection with the entering

5. Indemnification. 
 (a) Subject to the limitations and other provisions of this Section 5, the Company covenants and agrees to indemnify, defend and hold harmless the Investors and their respective directors,
officers, partners, managers, shareholders, members, employees, agents, representatives, successors, assigns and employees and each other Person, if any, who controls (within the meaning of the Securities Act) any such Investor or other Persons
(each, an “Investor Party”) from and against any and all Losses arising from claims by third parties resulting from, incurred in connection with or arising out of (but only to the extent of) (a) any breach of any
representation, warranty or covenant of the Company contained herein, (b) the failure of the Company to perform any of the Company’s agreements, covenants or obligations contained herein (other than if any such claim was a result of a
breach by the Investor under this Agreement) or (c) any action instituted against the Indemnitee by a third party with respect to the transactions contemplated by this Agreement. The term “Loss” or any similar term shall mean
any and all damages, deficiencies, costs, claims, fines, judgments, amounts paid in settlement, expenses of investigation, interest, penalties, taxes, assessments, out-of-pocket expenses (including reasonable attorneys’ and auditors’ fees
and disbursements, witness fees and court costs) but specifically excluding consequential, special, punitive, multiple and other similar damages. The party or parties being indemnified are referred to herein as the “Indemnitee” and
the indemnifying party is referred to herein as the “Indemnitor.” 

  
 10 

 (b) Indemnification Procedure. 

(1) Any party who receives notice of a potential claim that may, in the judgment of such party, result in a Loss shall use all
reasonable efforts to provide the parties hereto notice thereof within fifteen (15) days of the filing or other written assertion of any such claim against the Indemnitee, provided that failure or delay or alleged delay in providing such notice
shall not adversely affect such party’s right to indemnification hereunder, unless and then only to the extent that such failure or delay or alleged delay has resulted in actual prejudice to the Indemnitor, including, without limitation, by the
expiration of a statute of limitations. In the event that any party shall incur or suffer any Losses in respect of which indemnification may be sought by such party hereunder, the Indemnitee shall assert a claim for indemnification by written notice
(a “Notice”) to the Indemnitor stating the nature and basis of such claim. 
 (2) If indemnification is
sought, the Indemnitor shall, if necessary, retain counsel reasonably satisfactory to the Indemnitee, it being agreed that Goodwin Procter LLP is satisfactory, and have the option (i) to conduct any proceedings or negotiations in connection
therewith, (ii) to take all other steps to settle or defend any such claim (provided that the Indemnitor shall not settle any such claim without the consent of the Indemnitee which consent shall not be unreasonably withheld or delayed) and
(iii) to employ counsel to contest any such claim or liability in the name of the Indemnitee or otherwise. In any event, the Indemnitee shall be entitled to participate at its own expense and by its own counsel in any proceedings relating to
any third party claim. The Indemnitor shall, within fifteen (15) Business Days of receipt of the Notice, notify the Indemnitee of its intention to assume the defense of such claim. If (i) the Indemnitor shall decline to assume the defense
of any such claim, (ii) the Indemnitor shall fail to notify the Indemnitee within fifteen (15) Business Days after receipt of the Notice of the Indemnitor’s election to defend such claim or (iii) in the reasonable opinion of
counsel for the Indemnitee, the representation by the same counsel of the Indemnitor and the Indemnitee would be inappropriate due to actual or potential material differing interests between such Indemnitee and any other party represented by such
counsel in such proceeding, then in each such case the Indemnitor shall not have the right to direct the defense of such action on behalf of the Indemnitee and the Indemnitee shall, at the sole expense of the Indemnitor, defend against such claim;
provided, that the Indemnitee may not settle such claim without the consent of the Indemnitor (which consent will not be unreasonably withheld or delayed). The Indemnitor shall pay for only one separate legal counsel for the Indemnitees, and
such legal counsel shall be selected by the Investors. The reasonable expenses of all proceedings, contests or lawsuits in respect of such claims shall be borne and paid by the Indemnitor if the Indemnitee is entitled to indemnification hereunder
and the Indemnitor shall pay the Indemnitee, in immediately available funds, the amount of any Losses, within a reasonable time of the incurrence of such Losses. Regardless of which party shall assume the defense or negotiation of the settlement of
the claim, the parties agree to cooperate fully with one another in connection therewith. Anything in this Section 5 to the contrary notwithstanding, the Indemnitor shall not, without the Indemnitee’s prior written consent, settle
or compromise any claim or consent to entry of any judgment in respect thereof which imposes any future obligation on the Indemnitee or which does not include, as an unconditional term thereof, the giving by the claimant or plaintiff to the
Indemnitee, a release from all liability in respect of such claim.

giving notice to such Initial Investor Director and the Company, and the Company shall use its best efforts to effect the removal or replacement of any such Initial Investor Director. Subject to any limitations imposed by applicable law, the Initial

of Directors of the Company. 
 (3) The Company shall have the right to block an Initial Investor Director or an Additional
Investor Director designated by the Investors if such designee holds, or is nominated to hold, a management position or board seat at a company that the Board of Directors of the Company reasonably determines directly competes with the Company. If,
following the time when any person designated by the Investors is elected to the Board of Directors of the Company, such person is appointed or elected to any such position or seat at a company that the Board of Directors of the Company reasonably
determines directly competes with the Company, the Investors shall be entitled to designate a director to fill the vacancy resulting from such person’s resignation from the Board of Directors of the Company; provided, that such designee meets
the criteria that are reasonably acceptable to the nominating committee of the Board of Directors of the Company. 
 (4)

consolidated cash flows for the such period then ended (subject to normal year end audit adjustments). All such financial statements, including the related schedules and notes thereto, have been prepared in accordance with GAAP applied consistently
throughout the periods involved (except as approved by the aforementioned firm of accountants and disclosed therein). 
 (k)
No Change. Since March 31, 2013, there has been no development or event that has had or could reasonably be expected to have a Material Adverse Effect. 

  
 -5-

 (l) Ownership of Properties; Liens. The Issuer has good title to, or a valid
leasehold interest in, all Collateral owned by it. Each Group Company has good title to, or a valid leasehold interest in, all of its property (other than Intellectual Property) that is essential to its business as conducted on the Issue Date, and
none of any Collateral or other property is subject to any Lien except as permitted by Section 4.09 of the Indenture, or except as would not reasonably be expected to have a Material Adverse Effect or, with respect to any property that does not
constitute Collateral, except as contemplated by the Ericsson Sale Agreement (and the security documents referred to therein). For the avoidance of doubt, it is understood and agreed that any Group Company may, as part of its business, grant
licenses to third parties to use Intellectual Property owned or developed by such Group Company. 
 (m) Taxes. Each Group
Company has filed or caused to be filed all Federal, state and other material tax returns that are required to be filed and has paid all taxes shown to be due and payable on said returns or on any assessments made against it or any of its property
and all other taxes, fees or other charges imposed on it or any of its property by any Governmental Authority (other than any the amount or validity of which are currently being contested in good faith by appropriate proceedings and with respect to
which reserves in conformity with GAAP have been provided on the books of the Issuer); no tax Lien has been filed, and, to the knowledge of the Issuer, no claim is being asserted, with respect to any such tax, fee or other charge, other than as
would not reasonably be expected to have a Material Adverse Effect. 
 (n) Federal Regulations. No part of the proceeds
of the sale of any Notes, will be used (a) for “buying” or “carrying” any “margin stock” within the respective meanings of each of the quoted terms under Regulation U as now and from time to time hereafter in
effect for any purpose that violates the provisions of the regulations of the Board of Governors of the Federal Reserve System of the United States (or any successor) (the “Board”). 

(o) Labor Matters. Except as, in the aggregate, could not reasonably be expected to have a Material Adverse Effect: (a) there
are no strikes or other labor disputes against any Group Company pending or, to the knowledge of the Issuer, threatened; (b) hours worked by and payment made to employees of each Group Company have not been in violation of the Fair Labor
Standards Act or any other applicable Requirements of Law dealing with such matters; and (c) all payments due from any Group Company on account of employee health and welfare insurance have been paid or accrued as a liability on the books of
the relevant Group Company. 
 (p) ERISA. Except as would not reasonably be expected, individually or in the aggregate,
to have a Material Adverse Effect: (i) each employee benefit plan, within the meaning of Section 3(3) of ERISA, for which the Company or any ERISA Affiliate has any liability (each, a “Plan”) has been maintained in all
material respects in compliance with its terms and the requirements of any applicable statutes, orders, rules and regulations, including but not limited to ERISA and the Code; (ii) no prohibited transaction, within the meaning of
Section 406 of ERISA or Section 4975 of the Code, has occurred with respect to any Plan excluding transactions effected pursuant to a statutory or administrative exemption; 

  
 -6-

 
(iii) for each Plan that is subject to the funding rules of Section 412 of the Code or Section 302 of ERISA, no failure to satisfy the minimum funding standard of Section 412 of
the Code or Section 302 of ERISA, whether or not waived, has occurred or is reasonably expected to occur; (iv) with respect to each Plan that is subject to Title IV of ERISA, the fair market value of the assets of each Plan is no more than
$100,000 less than the present value of all benefits accrued under such Plan (determined based on those assumptions used to fund such Plan); (v) no “reportable event” (within the meaning of Section 4043(c) of ERISA) has occurred
or is reasonably expected to occur with respect to any Plan; and (vi) neither the Company nor any ERISA Affiliate has incurred, nor reasonably expects to incur, any liability under Title IV of ERISA (other than contributions to the Plan or
premiums to the Pension Benefit Guaranty Corporation (or any successor), in the ordinary course and without default) in respect of a Plan (including a “multiemployer plan”, within the meaning of Section 4001(a)(3) of ERISA).

 (q) Investment Company Act; Other Regulations. The Issuer is not an “investment company”, or a company
“controlled” by an “investment company”, within the meaning of the Investment Company Act of 1940, as amended. The Issuer is not subject to regulation under any Requirement of Law (other than Regulation X of the Board) that
limits its ability to incur Indebtedness. 
 (r) Accuracy of Information, No Undisclosed Liabilities. No statement or
information contained in this Agreement, any other Transaction Document or any other document, certificate or statement furnished by or on behalf of the Issuer to the Indenture Trustee or the Purchasers, or any of them, for use in connection with
the transactions contemplated by this Agreement or the other Transaction Documents, contained as of the date such statement, information, document or certificate was so furnished, any untrue statement of a material fact or omitted to state a
material fact necessary to make the statements contained herein or therein not misleading, when taken together with all statements contained in such documents and the Issuer’s filings and furnishings with the SEC. There is no fact known to the
Issuer that would reasonably be expected to have a Material Adverse Effect that has not been expressly disclosed herein, the Issuer’s filings and furnishings with the SEC, in the other Transaction Documents or in any other documents,
certificates and statements furnished to the Indenture Trustee and the Holders for use in connection with the transactions contemplated hereby and by the other Transaction Documents. 

(s) Senior Indebtedness. The Secured Obligations constitute senior secured indebtedness of the Issuer. The Secured Obligations are
secured by the Collateral on senior basis (but without regard to the control of remedies) to all other Indebtedness of the Issuer. The Issuer is not party to any other Indebtedness documentation or security agreements secured by the Collateral,
other than those relating to Subordinated Indebtedness. 
 (t) Security Documents. Each of the Indenture and each
Security Document is effective to create in favor of the Indenture Trustee, for the benefit of the Purchasers, a valid and enforceable security interest in the Collateral described therein and proceeds thereof. In the case of deposit accounts, when
Account Control Agreements are 

  
 -7-

 
entered into, the Indenture and each Security Document shall constitute a fully perfected Lien on, and security interest in, all right, title and interest of the Issuer in such Collateral and the
proceeds thereof, as security for the Secured Obligations (in the case of the Issuer), in each case prior and superior in right to any other Person. 
 (u) No Solicitation. No form of general solicitation or general advertising was used by the Issuer or its representatives in connection with the offer and sale of the Notes. No investors were
solicited or otherwise approached by the Issuer or any representative of the Issuer for the purpose of offering the Notes for sale who were not institutional investors. The Issuer has not issued or sold any Notes within the six-month period
immediately preceding the date hereof or securities that could be integrated with the Notes. Neither the Issuer nor any representative on its behalf has offered or sold, nor will any of them offer or sell, any Notes in any manner that would render
the issuance and sale of the Notes a violation of the Securities Act or any state securities or “Blue Sky” laws, or require registration pursuant thereto, nor has any of them authorized, nor will any authorize, any Person to act in such
manner. 
 (v) Registration Exemption. The offer and sale of the Notes to the Purchasers in the manner contemplated by
this Agreement will be exempt from the registration requirements of the Securities Act and it is not necessary to qualify an indenture in respect of the Notes. The Indenture is not required to be qualified under the Trust Indenture Act of 1939 (15
U.S.C. Sections 77aaa-77bbbb) as in effect on the date of this Agreement. 
 (w) No Other Sales Contracts. The
Issuer has not entered and will not enter into any contractual arrangement with respect to the distribution or sale of the Notes except for this Agreement and the Second Note Purchase Agreement. 

Section 3.2 Representations and Warranties of the Purchasers. Each Purchaser hereby represents and warrants to the Issuer
that as of the date hereof: 
 (a) Due Authorization. This Agreement has been duly executed and delivered on behalf of
each Purchaser. 
 (b) Binding Obligation. Assuming the due authorization, execution and delivery thereof by the other
parties thereto, this Agreement constitutes a valid and legally binding obligation of such Purchaser, enforceable in accordance with its respective terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar
laws of general applicability relating to or affecting creditors’ rights and to general equity principles. 
 (c) No
Violation. The execution, delivery and performance of this Agreement by such Purchaser and compliance with the terms and provisions hereof will not result in a breach or violation of any of the terms and provisions of, or constitute a default
under or conflict with, (i) any statute, rule, regulation or order of any governmental agency or body or any court, domestic or foreign, having jurisdiction over such Purchaser or any of its properties, (ii) any agreement or instrument to
which such Purchaser is a party or by which such Purchaser is bound or to which any of the properties of such Purchaser is subject, or (iii) the organizational documents of such Purchaser. 

  
 -8-

 (d) Purchaser Letter. Each Purchaser hereby delivers a letter in the form of Exhibit
A hereto (a “Purchaser Letter”) to the Issuer and makes the representations and warranties set forth in such Purchaser Letter to the Issuer. 
 (e) Securities Act. Each Purchaser represents and warranty that it is an “accredited investor”, as defined in Rule 501(a)(1), (2), (3) or (7) of Regulation D under the
Securities Act, that it will transfer interests in any Note only in accordance with the Indenture. 
 Section 3.3
Survival of Representations and Warranties. All representations and warranties contained herein shall survive the execution and delivery of this Agreement and the other Transaction Documents, the purchase or transfer by any Purchaser of any
Note or portion thereof or interest therein and the payment of any Note, and may be relied upon by any subsequent Holder of a Note, regardless of any investigation made at any time by or on behalf of such Purchaser or any other Holder of a Note. All
statements contained in any certificate or other instrument delivered by or on behalf of the Issuer pursuant to this Agreement shall be deemed representations and warranties of the Issuer under this Agreement. 

SECTION IV. INDEMNIFICATION 
 Section 4.1 The Issuer agrees to indemnify and hold harmless each of the Purchasers and their respective affiliates (including, without limitation, controlling persons) and each member, partner,
director, officer, employee, advisor, agent, affiliate, successor, partner, representative and assign of each of the forgoing (each an “Indemnified Person”) from and against any and all actions, suits, investigation, inquiry,
claims, losses, damages, liabilities, expenses or proceedings of any kind or nature whatsoever which may be incurred by or asserted against or involve any such Indemnified Person as a result of or arising out of or in any way related to or resulting
from the Transaction Documents, the use of proceeds thereof or the other transactions contemplated thereby (regardless of whether any such Indemnified Person is a party thereto and regardless of whether such matter is initiated by a third party or
otherwise) (any of the foregoing, a “Proceeding”), and the Issuer agrees to reimburse each Indemnified Person upon demand for any reasonable legal or other documented out-of-pocket expenses incurred in connection with investigating,
defending, preparing to defend or participating in any such Proceeding; provided, however, that no Indemnified Person will be indemnified for any such cost, expense or liability to the extent determined by a final, nonappealable
judgment of a court of competent jurisdiction to have resulted solely from the gross negligence, bad faith or willful misconduct of such Indemnified Person. In the case of any Proceeding to which the indemnity in this paragraph applies, such
indemnity and reimbursement obligations shall be effective, whether or not such Proceeding is brought by the Issuer or its securityholders or creditors, an Indemnified Person or any other person, or an Indemnified Person is otherwise a party thereto
and whether or not any aspect of the Transaction Documents or the transactions thereunder are consummated. Notwithstanding any other provision of this Transaction Documents, (i) no Indemnified Person shall be responsible or liable for damages
arising from the unauthorized use by others of information or other materials obtained through internet, electronic, telecommunications or other 

  
 -9-

 
information transmission and (ii) no Indemnified Person shall have any liability (whether direct or indirect, in contract, tort or otherwise) to the Issuer, or any of its securityholders or
creditors arising out of, related to or in connection with the Transaction Documents or the other transactions contemplated thereby, except to the extent of direct (as opposed to special, indirect, consequential or punitive) damages determined in a
final, nonappealable judgment by a court of competent jurisdiction to have resulted solely from such Indemnified Person’s gross negligence, bad faith or willful misconduct, and it is further agreed that the Purchasers shall have liability (if
any) only to the Issuer (as opposed to any other Person) and that each Purchaser shall be liable solely in respect of its own commitment under the Transaction Documents on a several, and not joint, basis with any other Purchaser. 

The Issuer will not, without the prior written consent of the Indemnified Person, settle, compromise, consent to the entry of any
judgment in or otherwise seek to terminate any Proceeding in respect of which indemnification may be sought hereunder (whether or not any Indemnified Person is a party thereto) unless such settlement, compromise, consent or termination
(i) includes an unconditional release of each Indemnified Person from all liability arising out of such Proceeding and (ii) does not include a statement as to, or an admission of, fault, culpability, or a failure to act by or on behalf of
such Indemnified Person.

	Re	Unwired Planet, Inc. Notes 

 Ladies and
Gentlemen: 
 This letter (the “Investor Letter”) is delivered by the undersigned (the
“Purchaser”) pursuant to that certain Note Purchase Agreement dated as of June 28, 2013 (as in effect, the “Note Purchase Agreement”), between Unwired Planet, Inc., as Issuer, and the Purchasers. Capitalized
terms used herein without definition shall have the meanings set forth in the Note Purchase Agreement. The Purchaser represents to and agrees with the Issuer as follows: 
 (a) The Purchaser is authorized to enter into the Note Purchase Agreement and to perform its obligations thereunder and to consummate the transactions contemplated thereby. 

(b) The Purchaser has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks
of its investment in the Notes, is experienced in investing in the capital markets and is able to bear the economic risk of such investment. The Purchaser is aware that investment in the Notes involves a high degree of risk, and the Notes are,
therefore, a speculative investment. 
 (c) The Purchaser has been afforded the opportunity to ask such questions as it deems
necessary to make an investment decision, and has received all information it has requested and deemed necessary in connection with making such investment decision. The Purchaser has, independently and without reliance upon any other Purchaser, and
based on such documents and information as it has deemed appropriate and adequate for such purpose, made its own appraisal of and investigation into the business, operations, property, financial and other condition, prospects and creditworthiness of
the Issuer, and made its own decision to purchase its interest in the Notes (including, without limitation, having considered the income tax consequences of purchasing, owning or disposing of the Notes in light of the Purchaser’s particular
situation and tax residence as well as any consequences arising under the laws of any taxing jurisdiction), and will, independently and without reliance upon any other Purchaser, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own analysis, appraisals and decisions in taking or not taking action under the Note Purchase Agreement, and to make such investigation as it deems necessary to inform itself as to the business,
operations, property, financial and other condition and creditworthiness of the Issuer. 

 (d) The Purchaser is an “accredited investor”, as defined in Rule 501(a)(1), (2),
(3) or (7), promulgated by the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”) or is a “qualified institutional buyer” (within
the meaning of Rule 144A thereunder) and is acquiring the Notes (or an interest in the Notes) for its own account for investment purposes. The Purchaser understands that the offering and sale of the Notes (or any interest in therein) has not been
and will not be registered under the Securities Act and has not and will not be registered or qualified under any applicable “Blue Sky” law, and that the offering and sale of the Notes (or any interests therein) have not been reviewed by,
passed on or submitted to any federal or state agency or commission, securities exchange or other regulatory body. 
 (d) The
Purchaser is not an employee benefit plan subject to Title I of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), or section 4975 of the Internal Revenue Code of 1986, as amended (the
“Code”) (each such plan, an “Employee Plan”), an entity whose underlying assets include the assets of any Employee Plan, or a governmental plan that is subject to any federal, state or local law which is
substantially similar to the provisions of Section 406 of ERISA or Section 4975 of the Code or the Purchaser’s purchase, holding and disposition of the Notes does not result in a prohibited transaction under Section 406 of ERISA
or Section 4975 of the Code (or, in the case of a governmental plan, any substantially similar federal, state or local law) for which an exemption is not available. 
 (e) The Purchaser is acquiring an interest in the Notes without a view to any distribution, resale or other transfer except as contemplated in the following sentence. The Purchaser will not resell or
otherwise transfer the Notes, or any interest or participation in the Notes, except in a transaction exempt from the registration requirements of the Securities Act, and applicable state securities or “blue sky” laws. The Purchaser
understands and acknowledges that the Issuer has not made or will be making any representation as to the availability of Rule 144A, Regulation S or Rule 144 under the Securities Act for the reoffer, resale, pledge or transfer of the Notes.

 (f) This Investor Letter has been duly executed and delivered and constitutes the legal, valid and binding obligation of the
Purchaser, enforceable against the Purchaser in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium or similar laws or equitable principles affecting the enforcement of
creditors’ rights generally and general principles of equity.
