This proxy is irrevocable and coupled with an interest.  Upon the sale or other transfer of the Shares, in whole or in part, or the assignment of the Warrant, this proxy shall automatically terminate (a) with respect to such sold or transferred Shares at the time of such sale and/or transfer or (b) with respect to all Warrant Shares in the case of an assignment in full of the Warrant or (c) with respect to such number of Warrant Shares as are underlying the portion of the Warrant assigned in the case of the assignment of a portion of the Warrant, at the time of such assignment, in each case, without any further action required by any person; provided, however, that this proxy shall not automatically terminate if such termination would cause any interest (including original issue discount) payable by any Company under the Obligations to a Person that is not a “United States person,” as defined in Section 7701(a)(30) of the Code, not to qualify as portfolio interest, within the meaning of Section 871(h)(2) or 881(c)(2) of the Code, as applicable, by reason of Section 871(h)(3) or 881(c)(3)(B) of the Code, as applicable, taking into account the constructive ownership rules under Section 871(h)(3)(C) of the Code.  All capitalized terms not otherwise defined herein shall have the meanings ascribed to them in the Security Agreement made as of November 23, 2007 (as the same may be amended, restated, extended or modified from time to time, the “Security Agreement”) by and among the Proxy Holder, STEN Credit Corporation, Stencor, Inc., EasyDrive Cars and Credit Corporation, LV Administrative Services, Inc., as Agent for the lenders from time to time party thereto, and certain parties listed on Exhibit A thereto.

Valens shall use its best efforts to forward to the Proxy Holder within two (2) business days following Valens’ receipt thereof, at the address for the Proxy Holder set forth above, copies of all materials received by Valens relating, in each case, to the solicitation of the vote of the shareholders of the Proxy Holder.

This proxy shall remain in effect with respect to the Shares during the period commencing on the date hereof and continuing until the earlier of (a) termination upon sale or other transfer of the Shares, in whole or in part, or the assignment of the Warrant as described above or (b) the indefeasible payment in full of all Obligations (as defined in the Security Agreement) owing by any Company (as defined in the Security Agreement) under and pursuant to the Security Agreement or any Ancillary Agreement (as defined in the Security Agreement).

Valens hereby covenants and agrees that, except for actions taken in furtherance of this proxy, the Security Agreement and any Ancillary Agreement, Valens (i) has not entered, and shall not enter at any time while this proxy remains in effect, into any voting agreement or voting trust with respect to the Shares, and (ii) has not granted, and shall not grant at any time while this proxy remains in effect, a proxy, consent or power of attorney with respect to the Shares.  During the term of this Agreement, Valens shall not take any action that would in any way restrict, limit or interfere with the performance of Valens’ obligations hereunder or the exercise and voting of the proxy by the Proxy Holder on a timely basis.
