AGREEMENT

NOW, THEREFORE, in consideration of the foregoing recitals and the mutual promises, representations, warranties, and covenants hereinafter set forth and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

1. AGREEMENT TO SELL AND PURCHASE.

1.1 Authorization of Shares. The Company has authorized the sale and issuance to Purchasers of the Shares. The Shares have been authorized pursuant to the Amended and Restated Certificate of Incorporation of the Company which has been filed with the Delaware Secretary of State on or about the date hereof (the “Restated Charter”).

1.2 Sale and Purchase. Subject to the terms and conditions hereof, at each Closing (as hereinafter defined) the Company hereby agrees to issue and sell to each Purchaser participating in such Closing, and each such Purchaser agrees to purchase from the Company, severally and not jointly, the number of Shares set forth opposite such Purchaser’s name on Exhibit A, at a purchase price of one dollar ($1.00) per share.

2. CLOSING, DELIVERY AND PAYMENT.

2.1 Initial Closing. The initial closing of the sale and purchase of the Shares under this Agreement (the “Initial Closing”) shall take place at 1:00 p.m. on the date hereof, at the offices of Cooley LLP, 4401 Eastgate Mall, San Diego, CA, 92121 or at such other time or place as the Company and Purchasers participating in the Initial Closing may mutually agree (such

date is hereinafter referred to as the “Initial Closing Date”). At the Initial Closing, the Company shall sell and each such Purchaser shall purchase, severally and not jointly, the number of Shares set forth opposite such Purchaser’s name on Exhibit A under the heading “Initial Closing Schedule of Purchasers”.

2.2 Delivery. At the Initial Closing, subject to the terms and conditions hereof, the Company will deliver to each Purchaser a certificate representing the number of Shares to be purchased at the Initial Closing by such Purchaser, against payment of the purchase price therefor by check or wire transfer made payable to the order of the Company.

2.3 U.S. Auto Parts Closing. If, at any time during the two years following the Initial Closing, the Board of Directors of the Company (the “Board”) determines in good faith that the Funding Milestone (as defined below) has been triggered by the Company, the Chief Executive Officer of the Company shall deliver a written notice (the “Funding Notice”) to U.S. Auto Parts Network, Inc. (“U.S. Auto Parts”), which Funding Notice shall certify that the Funding Milestone has occurred and shall specify the closing (the “Parts Closing” and together with the Initial Closing, each a “Closing”) of the purchase and sale of additional Shares to U.S. Auto Parts, such Parts Closing to occur no earlier than five and no later than 10 business days after the delivery of the Funding Notice (such date together with the Initial Closing Date, each a “Closing Date”). At the Parts Closing, the Company hereby agrees to issue and sell to U.S. Auto Parts, and U.S. Auto Parts agrees to purchase from the Company, the number of Shares set forth opposite U.S. Auto Parts’ name on Exhibit A under the heading “Parts Closing Schedule of Purchasers”. The sale of Shares made at the Parts Closing shall be made on the terms and conditions set forth in this Agreement, provided that (i) the representations and warranties of the Company and U.S. Auto Parts set forth in Section 3 below (and the Schedule of Exceptions) shall speak only as of the Initial Closing and the Company and U.S. Auto Parts shall have no obligation to update any such disclosures in connection with the Parts Closing and (ii) the representations and warranties of U.S. Auto Parts set forth in Section 4 hereof shall speak as of the Parts Closing. The Shares sold at the Parts Closing pursuant to this Section 2.3 shall be deemed to be “Shares” for all purposes under this Agreement and following the Parts Closing U.S. Auto Parts shall be deemed to be a “Purchaser” for all purposes under this Agreement. For purposes of this Section 2.3, the “Funding Milestone” shall mean the simultaneous occurrence of (i) the Company having less than $2,000,000 in cash and cash equivalents (as determined pursuant to United States generally accepted accounting principles) and (ii) the Company having less than 5,000 third parties (e.g., an automobile repair shop) that as part of their business install or replace automobile parts, that are approved by the Company as being permitted to submit a quotation displayed on the Company’s website in response to an end user’s query that provides a price quote for an auto repair service with respect to that end user’s automobile (such approved third parties, “Approved Company Repair Shops”); provided, however, that, notwithstanding the foregoing, on the date that is (i) the one year anniversary of this Agreement, the “Funding Milestone” shall mean the Company having less than 2,000 Approved Company Repair Shops (irrespective of the amount of cash and cash equivalents held by the Company on such date) and (ii) the two year anniversary of this Agreement, the “Funding Milestone” shall mean the Company having less than 5,000 Approved Company Repair Shops (irrespective of the amount of cash and cash equivalents held by the Company on such date). For the avoidance of doubt, the parties to this Agreement acknowledge and agree that following the date that is the two year anniversary of this Agreement, the Funding Milestone cannot be triggered, and this Section 2.3 shall automatically terminate and be of no further force or effect, including, without limitation, the obligation of U.S. Auto Parts to purchase Shares at the Parts Closing.

Purchaser understands that the Company has no present intention of registering the Shares or any shares of its Common Stock. Purchaser also understands that there is no assurance that any exemption from registration under the Securities Act will be available and that, even if available, such exemption may not allow Purchaser to transfer all or any portion of the Shares under the circumstances, in the amounts or at the times Purchaser might propose.

Purchaser has been advised or is aware of the provisions of Rule 144, which permits limited resale of shares purchased in a private placement subject to the satisfaction of certain conditions, including, among other things: the availability of certain current public information about the Company, the resale occurring following the required holding period under Rule 144 and the number of shares being sold during any three-month period not exceeding specified limitations.

(g) Residence.
