Dear Lanny:

This letter is to confirm our offer of employment with Honeycomb Acquisition, Inc. (to be merged with and into ZipRealty, Inc.) (the “Company”), which following the Merger (as defined in the Merger Agreement), will be a wholly-owned indirect subsidiary of Realogy Group LLC (“Parent”), which in turn is an indirect subsidiary of Realogy Holdings Corp. This offer is being made in connection with, and subject to the consummation of, the acquisition of ZipRealty, Inc. by Parent pursuant to the Agreement and Plan of Merger dated as of July 15, 2014 by and among ZipRealty, Inc., Parent, and Honeycomb Acquisition, Inc. (the “Merger Agreement”).

Terms of Employment

Your title will be Chief Executive Officer of ZipRealty, Inc. You will report to the President and Chief Executive Officer of the Realogy Franchise Group, which following the Merger will be an affiliate of ZipRealty, Inc. (“RFG”). This position is classified as Level 2 in Parent’s job structure. This offer is contingent upon satisfactory background verification, as well as compliance with federal immigration employment law requirements.

Your annualized base salary will be $400,000, prorated for partial years of employment. The base salary is subject to increase in the future. You will participate in the Company’s employee benefit plans on the same basis as other senior executives, subject to the terms and conditions of the applicable plans (which the Company reserves the right to amend or terminate at any time). You and similarly-situated executives do not accrue vacation; however, it is expected that you will be able to take up to 4 weeks off per year (prorated for partial years) pursuant to the Company’s paid time-off policy. Attached is a Confidentiality and Non-Disclosure Agreement which you are required to review, sign and return to me on a date to be determined.

Your target annual bonus will be 50% of your “eligible earnings” (approximately annual base salary), subject to achievement of goals for Level 2 RFG as specified by the Compensation Committee of the board of directors of Realogy Holdings Corp. For 2014 only, “eligible earnings” will be defined as the total base salary actually earned from January 1, 2014 through December 31, 2014 and the Company will guarantee payout of 50% of the targeted bonus amount based on these eligible earnings (which includes base salary actually earned at ZipRealty, Inc. pre-closing).

In addition, you will be recommended for a Realogy Holdings Corp. equity grant, subject to the approval by the Compensation Committee of the board of directors of Realogy Holdings Corp. This equity award will be valued at $1.2 million (using Realogy Holdings Corp.’s standard valuation procedures). 40% of the award will be in the form of time-based stock options and 60% in the form of performance-based restricted shares (with the performance goals to be mutually agreed prior to the closing of the transaction), and the award will include such other terms as determined by the Compensation Committee. Such recommended equity award will be submitted to the Compensation Committee for consideration at its next meeting to review such awards, which generally occurs prior to the quarterly earnings release. You are also eligible to participate in Parent’s annual equity award cycle in accordance with Parent’s equity grant practices for similarly situated employees at the time of grant, subject to the approval of the Compensation Committee of the board of directors of Realogy Holdings Corp. Your acceptance of any Realogy Holdings Corp. equity grants is subject to the execution of all required agreements that may be in effect at the time of grant, including, but not limited to, a post-employment non-solicitation agreement.

By accepting this position, you are representing that: (i) your assumption and performance of the duties with the Company or its affiliates contemplated by this offer letter will not violate or conflict with any agreement, instrument, statute, rule or regulation, or any decree, judgment or order of any court or other governmental authority by which you are bound, and (ii) you are not a party to or bound by any agreement or instrument which would prevent you from performing in any way your duties contemplated by this offer letter, including without limitation any employment agreement, covenant not to compete, covenant not to solicit or hire, separation agreement or confidentiality agreement with any person or entity. You also agree that you shall not, during your employment with the Company, improperly use or disclose to the Company or its affiliates or any of the employees or agents (including sales associates) of the Company or its affiliates any proprietary information or trade secret belonging to any former employer of yours or any other person or entity to which you owe a duty of non-disclosure.

You are eligible for reimbursement for business related expenses, provided such expenses are incurred and submitted in accordance with the Realogy Travel & Expense policy in effect at the time expenses are submitted for payment.

NOW, THEREFORE, in consideration of the foregoing, including, but not limited to, the Company’s employment of Employee, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Company and Employee hereby covenant and agree as follows:

1. In addition to the Confidential Information identified above, the Company may from time to time furnish to Employee financial, technical, legal, marketing, or other proprietary or confidential reports, analyses, records, pricing information, data, computer programs, systems or output, information, or other material relating to the Company and/or work done for its clients and customers, in oral, written or other format, developed by the Company and/or others, which the Company deems and Employee should consider proprietary and confidential to, and of independent economic value to, the Company, actual or potential, regardless whether otherwise protectable under any law, and regardless of protections, lack of markings or dissemination (collectively, the “Company Confidential Information”).

2. Employee agrees that, during the term of Employee’s employment with the Company and thereafter, all Company Confidential Information shall be treated as proprietary and confidential to the Company. Furthermore, Employee agrees that, except in furtherance of the Company’s business, Employee will not disclose or permit disclosure of such Company Confidential Information to any third party unless

It is further understood and agreed that all written documentation and all work done or prepared by Employee during his employment (the “Works”) with the Company shall be deemed as “work made for hire” for the Company under the United States Copyright Laws (17 U.S.C.
