Ladies and Gentlemen:
We have examined the Registration Statement on Form S-8 (the “Registration Statement”) to be filed by InfoSpace, Inc., a Delaware corporation, with the Securities and Exchange Commission on or about the date hereof, in connection with the registration under the Securities Act of 1933, as amended, of 5,000,000 shares of your common stock, par value $0.0001 per share (the “Shares”), reserved for issuance under the InfoSpace, Inc. Restated 1996 Flexible Stock Incentive Plan (the “Plan”). As your legal counsel, we have reviewed the actions proposed to be taken by you in connection with the issuance and sale of the Shares to be issued under the Plan.
It is our opinion that, when issued and sold in the manner referred to in the Plan and pursuant to the agreements which accompany the Plan, the Shares will be duly authorized, legally and validly issued, fully paid and nonassessable.
We consent to the use of this opinion as an exhibit to the Registration Statement, and further consent to the use of our name wherever appearing in the Registration Statement and any amendments thereto. In giving such consent, we do not consider that we are “experts” within the meaning of such term as used in the Securities Act, or the rules and regulations of the Securities and Exchange Commission issued thereunder, with respect to any part of the Registration Statement, including this opinion as an exhibit or otherwise.
