EXHIBIT l

Indemnification Provisions

The Company agrees to indemnify and hold harmless Roth and its affiliates (as defined in Rule 405 under the Securities Act of 1933, as amended) and their respective directors, officers, employees, agents and controlling persons (Roth and each such person being an "Indemnified Party") from and against all losses, claims, damages and liabilities (or actions, including shareholder actions, in respect thereof), joint or several, to which such Indemnified Party may become subject under any applicable federal or state law, or otherwise, which are related to or result from the performance by Roth of the services contemplated by or the engagement of Roth pursuant to this Agreement and will promptly reimburse any Indemnified Party for all reasonable expenses (including reasonable counsel fees and expenses) as they are incurred in connection with the investigation of, preparation for or defense arising from any threatened or pending claim, whether or not such Indemnified Party is a party and whether or not such claim, action or proceeding is initiated or brought by the Company. The Company will not be liable to any Indemnified Party under the foregoing indemnification and reimbursement provisions (i) for any settlement by an Indemnified Party effected without its prior written consent (not to be unreasonably withheld); or (ii) to the extent that any loss, claim, damage or liability is found in a final, non-appealable judgment by a court of competent jurisdiction to have resulted from the Indemnified Party's willful misconduct or gross negligence. The Company also agrees that no Indemnified Party shall have any liability (whether direct or indirect, in contract or tort or otherwise) to the Company or its security holders or creditors related to or arising out of the engagement of Roth pursuant to, or the performance by Roth of the services contemplated by, this Agreement except to the extent that any loss, claim, damage or liability is found in a final, non-appealable judgment by a court of competent jurisdiction to have resulted from Roth's willful misconduct or gross negligence.

Promptly after receipt by an Indemnified Party of notice of any intention or threat to commence an action, suit or proceeding or notice of the commencement of any action, suit or proceeding, such Indemnified Party will, if a claim in respect thereof is to be made against the Company pursuant hereto, promptly notify the Company in writing of the same. Any failure or delay by an Indemnified Party to give the notice referred to in this paragraph shall not affect such Indemnified Party's right to be indemnified hereunder, except to the extent that such failure or delay causes actual material harm to the Company, or materially prejudices its ability to defend such action, suit or proceeding on behalf of such Indemnified Party. ln case any such action is brought against any Indemnified Party and such Indemnified Party notifies the Company of the commencement thereof, the Company may elect to assume the defense thereof, with counsel reasonably satisfactory to such Indemnified Party, and an Indemnified Party may employ counsel to participate in the defense of any such action provided, that the employment of such counsel shall be at the Indemnified Party's own expense, unless (i) the employment of such counsel at Company expense has been authorized in writing by the Company, (ii) the Indemnified Party has reasonably concluded (based upon advice of counsel to the Indemnified Party) that there are legal defenses available to the Indemnification Party that are not available to the Company, or that there exists a conflict or potential conflict of interest (based upon advice of counsel to the Indemnified Party) between the Indemnified Party and the Company that makes it impossible or inadvisable for counsel to the Company to conduct the defense of both parties (in which case the Company will not have the right to direct the defense of such action on behalf of the Indemnified Party), or (iii) the Company has not in fact employed counsel reasonably satisfactory to the Indemnified Party to assume the defense of such action within a reasonable time after receiving notice in writing of the action, suit or proceeding, in each of which cases the reasonable fees, disbursements and other charges of such counsel will be at the expense of the Company; provided, further, that in no event shall the Company be required to pay fees and expenses for more than one firmof attorneys (and local counsel) representing Indemnified Parties.

If the indemnification provided for in this Agreement is for any reason held unenforceable by an Indemnified Party, the Company agrees to contribute to the losses, claims, damages and liabilities for which such indemnification is held unenforceable (i) in such proportion as is appropriate to reflect the relative benefits to the Company, on the one hand, and Roth on the other hand, of a PO whether or not a PO is consummated or, (ii) if (but only if) the allocation provided for in clause (i) is for any reason unenforceable, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company, on the one hand and Roth, on the other hand, as well as any other relevant equitable considerations. The Company agrees that for the purposes of this paragraph the relative benefits to the Company and Roth of a PO as contemplated shall be deemed to be in the same proportion that the total value received or contemplated to be received by the Company in connection with a PO bear to the fees paid or to be paid to Roth under this Agreement. Notwithstanding the foregoing, the Company expressly agrees that Roth shall not be required to contribute any amount in excess of the amount by which fees paid to Roth hereunder (excluding reimbursable expenses), exceeds the amount of any damages which Roth has otherwise been required to pay.

The Company agrees that without Roth's prior written consent, which shall not be unreasonably withheld, it will not settle, compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding in respect of which indemnification could be sought under the indemnification provisions of this Agreement (whether or not Roth or any other Indemnified Party is an actual or potential party to such claim, action or proceeding), unless such settlement, compromise or consent includes an unconditional release of each Indemnified Party from all liability arising out of such claim, action or proceeding.

In the event that an Indemnified Party is requested or required to appear as a witness in any action brought by or on behalf of or against the Company in which such Indemnified Party is not named as a defendant, the Company agrees to promptly reimburse Roth on a monthly basis for all reasonable out-of-pocket expenses incurred by it in connection with such Indemnified Party's appearing and preparing to appear as such a witness and for which receipts are presented, including, without limitation, the reasonable fees and disbursements of its legal counsel.

If multiple claims are brought with respect to at least one of which indemnification is permitted under applicable law and provided for under this Agreement, the Company agrees that any judgment or arbitration award shall be conclusively deemed to be based on claims as to which indemnification is permitted and provided for, except to the extent the judgment or arbitration award expressly states that it, or any portion thereof, is based solely on a claim as to which indemnification is not available.
