On January 10, 2013, Unwired Planet, Inc. and certain of its subsidiaries (collectively referred to as the "Company" or "UP"), including its indirect subsidiary, Unwired Planet, LLC ("UP LLC"), entered into a Master Sale Agreement (the "MSA") with Telefonaktiebolaget L M Ericsson (publ) and an indirect subsidiary (collectively referred to herein as "Ericsson") pursuant to which such subsidiary of Ericsson will transfer and sell 2,185 patents and patent applications (the "Ericsson Transferred Patent Portfolio") to UP LLC in exchange for certain ongoing rights to revenues generated from the Ericsson Transferred Patent Portfolio and the Company's patent portfolio, as summarized below (the "Patent Purchase"). At or prior to the closing, UP will transfer all of its patents not previously transferred to UP LLC. The Ericsson Transferred Patent Portfolio consists of 825 patent families and includes 1,922 issued patents and 263 patent applications covering technology utilized in telecommunications infrastructure including signal processing, network protocols, radio resource management, voice/text applications, mobility management, software, hardware and antennas. Of the 1,922 issued patents, 753 are United States patents. Pursuant to the MSA, during the period commencing on January 1, 2014 and ending five years thereafter, Ericsson also will assign to UP LLC, for no additional consideration, 100 patents each year (a portion of which will be United States patents) selected by Ericsson (the "Additional Patents"), provided that Ericsson may choose to accelerate such contribution to be made at one time or over a shorter period of time. Capitalized terms used but not defined in this Current Report on Form 8-K (this "Report") are defined in the MSA.

In consideration for the Ericsson Transferred Patent Portfolio and the Additional Patents, UP will pay Ericsson the following portion of UP LLC's cumulative gross revenue on a quarterly basis in accordance with the provisions of the MSA (the "Gross Revenue Payments"): (i) 20% of the amount of Cumulative Gross Revenue, until the Cumulative Gross Revenue equals $100 million; plus
(ii) 50% of the amount of Cumulative Gross Revenue in excess of $100 million, until the Cumulative Gross Revenue equals $500 million; plus (iii) 70% of the amount of Cumulative Gross Revenue in excess of $500 million. Revenue sharing may be adjusted in Ericsson's favor in certain circumstances as described below.

The MSA also provides that in connection with a UP Change of Control, Ericsson will have the right either to (i) terminate the MSA and receive a cash payment (the "Sale Payment") or (ii) elect to continue the MSA in full force and effect and not receive the Sale Payment. In the event Ericsson elects to receive the Sale Payment, such Sale Payment will be equal to Ericsson's share of the fair market value of all patents and other assets owned or held by UP LLC (the "Patent FMV"). The Patent FMV will be determined in accordance with the mechanism set forth in the MSA. After such Patent FMV has been determined it will be deemed incremental "Cumulative Gross Revenue" and distributed in accordance with the formula for Gross Revenue Payments set forth above. Notwithstanding the foregoing, if a UP Change of Control occurs within three years of the consummation of the transactions contemplated by the MSA and Ericsson elects to receive the Sale Payment, the Sale Payment will be at least $1.05 billion less Gross Revenue Payments actually received by Ericsson prior to the consummation of the UP Change of Control.

Pursuant to the MSA and certain Ancillary Agreements, UP LLC granted or will grant Ericsson licenses and other rights under the Ericsson Transferred Patent Portfolio and all other Patents owned or controlled by UP LLC. The Ericsson Transferred Patent Portfolio is also subject to certain encumbrances relating to existing Ericsson licensees. UP LLC remains unrestricted in the licensing of its existing patent portfolio without any additional encumbrances as a result of the transaction. Additionally, pursuant to the MSA, UP has agreed not to engage in, or provide services to any Person who conducts or otherwise engages in, the business of generating revenue or otherwise monetizing Patents through licensing or selling of Patents or initiation or participation in litigation or other legal proceedings to protect and enforce any Patent or any other intellectual property right or any other business that is competitive with the business of UP
LLC. During a specified period following the closing of the Patent Purchase, with respect to certain patents, the MSA establishes revenue sharing adjustments in favor of Ericsson if UP LLC grants licenses (or similar rights) below certain agreed-upon royalty rates. Additionally, pursuant to the MSA with respect to the Ericsson Transferred Patent Portfolio and to the extent applicable, UP LLC has accepted an obligation to behave in a manner that is fair, reasonable and non-discriminatory ("FRAND"). The aggregate result of these commitments together with other obligations contained in these documents is such that UP LLC will pursue recurring revenue license arrangements that reflect the fair value of its entire patent portfolio, while at the same time respecting Ericsson's existing commitments, customers and, to the extent applicable, any FRAND obligations. UP LLC believes that such an approach will maximize value for its shareholders over the long term, but such arrangements may take a longer period of time to achieve . . .

In connection with the Patent Purchase, the Company engaged Evercore Group L.L.C. ("Evercore") to provide financial advisory services pursuant to a letter agreement entered into on January 10, 2013 (the "Letter Agreement"). Among other things, the Letter Agreement provides that in consideration for the advisory services provided by Evercore, the Company will pay Evercore fees in connection with the Patent Purchase in the form of shares (the "Shares") of the Company's common stock, par value $0.001 per share (the "Common Stock"). Pursuant to the Letter Agreement, one million Shares shall be issued following the consummation of the Patent Purchase and up to 1.2 million additional Shares shall be issued, if at all, depending upon the volume weighted average trading price of the Company's Common Stock during the two-year period following the consummation of the Patent Purchase (the "Completion") as follows (the "Post-Completion Success Fees"):

• If during the one-year period following Completion, the volume weighted average trading price of the Common Stock over any 20 consecutive trading days equals or exceeds $3.00, the Company shall issue Evercore an additional 500,000 Shares; and

• If during the two-year period following Completion, the volume weighted average trading price of the Common Stock over any 20 consecutive trading days equals or exceeds $5.00, the Company shall issue Evercore an additional 700,000 Shares.

The Letter Agreement also provides that the Company will pay Evercore a cash fee in lieu of the Post-Completion Success Fees if a change of control of the Company occurs within two years from the date of Completion.

The Shares shall be issued to Evercore in reliance upon exemptions from registration pursuant to Section 4(2) under the Securities Act of 1933, as amended (the "Securities Act"), and the rules and regulations promulgated thereunder. The Letter Agreement contains representations to support the Company's reasonable belief that Evercore had access to information concerning the Company's operations and financial condition, that Evercore is acquiring the Shares for its own account and not with a view to the distribution thereof, and that Evercore is an "accredited investor" as defined by Rule 501 promulgated under the Securities Act.
