Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions:

On May 7, 2013, Market Leader, Inc. (“Market Leader”) entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Trulia, Inc., a Delaware corporation (“Trulia”), and Mariner Acquisition Corp., a Washington corporation and a wholly owned subsidiary of Trulia (“Merger Sub”). Pursuant to the terms, and subject to the conditions, of the Merger Agreement, at the closing of the proposed transactions contemplated by the Merger Agreement, Merger Sub will be merged with and into Market Leader (the “Merger”), and Market Leader will continue as the surviving corporation of the Merger and as a wholly owned subsidiary of Trulia.

The Merger Agreement was unanimously approved by the Board of Directors of each of Trulia and Market Leader, and Market Leader has agreed to convene a special meeting of its shareholders to consider and vote upon the Merger Agreement and the Merger.

Effect of the Merger on Market Leader Common Stock, Stock Options, Restricted Stock Units and Stock Appreciation Rights

At the effective time of the Merger, each outstanding share of Market Leader common stock (other than shares with respect to which dissenter’s rights are properly exercised or shares owned by Trulia, any of its subsidiaries or Market Leader) will be converted into the right to receive (i) 0.1553 of a share of Trulia common stock (the “Stock Consideration”) plus (ii) $6.00 in cash, without interest, and in each case subject to applicable withholding tax (the “Cash Consideration” and, together with the Stock Consideration, the “Merger Consideration”).

In connection with the Merger, except as provided in the following paragraph, each outstanding Market Leader stock option, stock appreciation right and restricted stock unit held by a service provider of Market Leader who continues to be a service provider to Trulia, the surviving corporation in the Merger, or any of their respective subsidiaries (each such person a “continuing service provider”), will be assumed and converted into a corresponding equity award to purchase or acquire shares of common stock of Trulia. The terms of each assumed equity award will be the same except that the number of shares subject to each equity award and the per share exercise price, if any, will be adjusted by an exchange ratio formula set forth in the Merger Agreement. At its discretion, Trulia may elect to assume the remaining share reserve under Market Leader’s existing equity incentive plan at the time of the closing of the Merger.

Notwithstanding the foregoing, if the aggregate number of shares of Trulia common stock issued or issuable in the Merger (including shares of Trulia common stock issuable in respect of assumed Market Leader equity awards) exceeds 19.9% of the number of shares of Trulia common stock outstanding immediately prior to the effective time of the Merger (the “19.9% Threshold”), then certain vested Market Leader stock options and stock appreciation rights would not be assumed and instead would be terminated in exchange for a cash payment with respect to each share of Market Leader common stock underlying any such award-equal to (i) $6.00 plus (ii) the volume weighted average closing price of Trulia common stock for the ten (10) trading days immediately preceding (but not including) the date of the closing of the Merger (the “Closing Average”), multiplied by 0.1553 minus (iii) the per share exercise price of such award (the “Cash-Out”), net of applicable withholding taxes. If the per share exercise price of an award not assumed pursuant to this paragraph exceeds the sum of (i) and (ii), then such award would terminate without consideration.

In addition, if, following the Cash-Out, the aggregate number of shares of Trulia common stock issued or issuable in the Merger (including shares of Trulia common stock issuable in respect of assumed Market Leader equity awards) would still exceed the 19.9% Threshold, the aggregate Stock Consideration would be decreased to the minimum extent necessary such that the number of shares of Trulia common stock issued or issuable in the Merger (including shares of Trulia common stock issuable in respect of assumed Market Leader equity awards) would not exceed the 19.9% Threshold. In such event, the aggregate Cash Consideration would be increased by an amount equal to the product of (i) the amount of the reduction in the aggregate Stock Consideration multiplied by (ii) the Closing Average.

The Merger will be a taxable transaction for U.S. federal and applicable state and local income tax purposes.

Other Terms and Conditions of the Merger Agreement

Market Leader and Trulia each made customary representations, warranties and covenants in the Merger Agreement, including, among others, covenants of Market Leader to (i) convene a meeting of its shareholders to consider and vote upon the Merger Agreement and the Merger, (ii) subject to certain exceptions, have Market Leader’s Board of Directors recommend that the Market Leader shareholders approve the Merger Agreement, (iii) refrain from, among other things, (1) soliciting proposals relating to alternative business combination transactions and (2) subject to certain exceptions, entering into discussions or furnishing non-public information relating to alternative business combination transactions and (iv) subject to certain exceptions, conduct its business in the ordinary course and refrain from taking certain actions during the period between the date of the execution of the Merger Agreement and the consummation of the Merger.

The consummation of the Merger is subject to customary closing conditions, including, among others, (i) obtaining the approval of the shareholders holding a majority of the outstanding shares of Market Leader common stock, (ii) the effectiveness under the Securities Act of 1933, as amended, of the Registration Statement on Form S-4 relating to the issuance of the shares of Trulia common stock in the Merger, (iii) approval of the listing on the New York Stock Exchange of the shares of Trulia common stock to be issued in the Merger, (iv) expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and (v) absence of any law, regulation or order that that has the effect of making the Merger illegal or otherwise preventing the consummation of the Merger.

The Merger Agreement contains certain termination rights for both Trulia and Market Leader, including for the failure to consummate the Merger by October 31, 2013, the enactment, promulgation or issuance of any law, regulation or judicial order prohibiting consummation of the Merger, failure of Market Leader’s shareholders to approve the Merger Agreement, or breaches of representations, warranties or covenants by a party that result in the failure of certain conditions to closing being satisfied. In addition, Trulia has the right to terminate the Merger Agreement in the event that the Market Leader Board of Directors changes its recommendation in favor of the Merger Agreement, Market Leader breaches its non-solicitation and related covenants, and under certain similar circumstances. The Merger Agreement provides that, in connection with the termination of the Merger Agreement under certain specified circumstances, Market Leader would be required to pay Trulia a termination fee of $15.0 million. In addition, under certain specified circumstances Market Leader would be required to reimburse Trulia’s transaction expenses (subject to a cap of $1.0 million).

The foregoing description of the Merger Agreement is only a summary, does not purport to be complete, and is qualified in its entirety by reference to the full text of the Merger Agreement which is attached to this Current Report on Form 8-K as Exhibit 2.01 and is incorporated herein by reference in its entirety. The Merger Agreement has been attached to provide investors with information regarding its terms. It is not intended to provide any other factual information about Market Leader or Trulia. The Merger Agreement should not be read alone, but should instead be read in conjunction with the other information regarding Market Leader or Trulia, their respective affiliates or their respective businesses, the Merger Agreement and the Merger that will be contained in, or incorporated by reference into, the Registration Statement on Form S-4 that will include a proxy statement of Market Leader and a prospectus of Trulia, as well as in the Forms 10-K, Forms 10-Q and other filings that each of Market Leader and Trulia make with the Securities and Exchange Commission. The Merger Agreement contains representations and warranties made by Market Leader to Trulia and made by Trulia to Market Leader. The assertions embodied in the representations and warranties were made solely for purposes of the Merger Agreement and may be subject to important qualifications and limitations agreed to by the parties to the Merger Agreement in connection with negotiating its terms. In particular, in reviewing the representations and warranties contained in the Merger Agreement, it is important to bear in mind that the representations and warranties were made solely for the benefit of the parties to the Merger Agreement and were negotiated for the purpose of allocating contractual risk among the parties to the Merger Agreement rather than to establish matters as facts. The representations and warranties may also be subject to a-standard of materiality or material adverse effect different from those generally applicable to investors and reports and documents filed with the Securities and Exchange Commission and in some cases may be qualified by disclosures made by one party to the other which are not necessarily reflected in the Merger Agreement. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in the parties’ public disclosures. For the foregoing reasons, the representations, warranties and covenants or any descriptions of those provisions should not be relied upon as characterizations of the actual state of facts or condition of Market Leader or Trulia or any of their respective subsidiaries or affiliates.

Voting Agreement

In connection with entering into the Merger Agreement, Trulia and each of the directors and executive officers of Market Leader, in their individual capacities (collectively, the “Supporting Shareholders”), entered into voting agreements (the “Voting Agreements”) pursuant to which the Supporting Shareholders agreed to, among other things, vote their shares of Market Leader common stock (i) in favor of the approval of the Merger Agreement and (ii) against approval of any proposal made in opposition to, in competition with, or inconsistent with, the Merger Agreement or the Merger or any other transactions contemplated by the Merger Agreement. In addition, the Supporting Shareholders agreed not to directly or indirectly transfer their respective shares of Market Leader common stock during the term of the Voting Agreement. Collectively, the Supporting Shareholders represent approximately 11.1% of Market Leader’s total shares outstanding.

The foregoing description of the Voting Agreement is only a summary, does not purport to be complete, and is qualified in its entirety by reference to the form of Voting Agreement which is attached as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference in its entirety.
