May 1, 2001 255 Broadway New York, New York Ladies and Gentlemen: In connection with our engagement of Atlas Capital Services Inc. ("Atlas Capital Services") as finder, we hereby agree to indemnify and hold harmless Atlas Capital Services and its affiliates, and the respective directors, officers, shareholders, agents and employees of Atlas Capital Services (collectively the "Indemnified Persons"), from and against any and all claims, actions, suits, proceedings (including those of shareholders), damages, liabilities and expenses as incurred by any of them (including the reasonable fees and expenses of counsel) which (A) relate to or arise out of (i) any actions taken or omitted to be taken (including any untrue statements made to any Indemnified Person in connection with our engagement of Atlas Capital Services, or (B) otherwise relate to or arise out of Atlas Capital Services' activities on our behalf under Atlas Capital Services' engagement, and we shall reimburse any Indemnified Person for all expenses (including the reasonable fees and expenses of counsel) as incurred by such Indemnified Person in connection with investigating, preparing or defending any such claim, action , suit or proceeding (collectively a "Claim"), in connection with pending or threatened litigation in which any Indemnified Person is a party. We will not, however, be responsible for any Claim which is finally judicially determined to have resulted exclusively from the gross negligence of willful misconduct of any person seeking indemnification hereunder. We further agree that no Indemnified Person shall have any liability to us for or in connection with our engagement of Atlas Capital Services except for any Claim incurred by us solely as a direct result of any Indemnified Person's gross negligence or willful misconduct. We further agree that we will not, without the prior written consent of Atlas Capital Services, settle, compromise or consent to the entry of any judgment in any pending or threatened Claim in respect of which indemnification may be reasonably sought hereunder (whether or not any Indemnified Person is an actual or potential party to such Claim), unless such settlement, compromise or consent includes an unconditional, irrevocable release of each Indemnified Person against whom such claim may be brought hereunder from any and all liability arising out of such claim. Promptly upon receipt by an Indemnified Person of notice of any complaint or the assertion or institution of any Claim with respect to which indemnification is being sought hereunder, such Indemnified Person shall notify us in writing of such complaint or of such assertion or institution but failure to do so notify us shall not relieve us from any obligations we may have hereunder, unless and only to the extent such failure results in the forfeiture by us of substantial rights and defenses, and will not in any event relieve us from any other obligation or liability we may have to any Indemnified Person, we will assume the defense of such Claim, including the employment of counsel reasonably satisfactory to such Indemnified Person and the payment of reasonable fees and expenses of such counsel. In the event, however, that such Indemnified Person reasonably determines that having common counsel with the Company and/or another Indemnified Person would present such counsel with a conflict of interest or if the defendant in, or target of, any such Claim, includes an Indemnified Person and us, and such Indemnified reasonably concludes that there may be legal defenses available to it or other Indemnified Persons different from or in addition to those available to us, then such Indemnified Person may employ its own separate counsel to represent or defend it in any such Claim and we shall pay the reasonable fees and expenses of such counsel. Notwithstanding anything herein to the contrary, if we fail timely or diligently to defend, contest, or otherwise protect against any Claim, the relevant Indemnified Person shall have the right, but not the obligation, to defend, contest, compromise, settle, assert crossclaims, or counterclaims or otherwise protect against the same, and shall be fully indemnified by us therefore, including without limitation, for the reasonable fees and expenses of its counsel and all amounts paid as a result of such Claim or the compromise or settlement thereof. In any Claim in which we assume the defense, the Indemnified Person shall have the right to participate in such Claim and to retain its own counsel therefore at its own expense. We agree that if any indemnity sought by an Indemnified Person hereunder is held by a court to be unavailable for any reason, then (whether or not Atlas Capital Services is the Indemnified Person), we and - ------------------------------------------------------------------------------------------------------------ 225 Broadway, Suite 910 New York, NY 10007 U.S.A. Phone 212.267.3500 Fax: 212.267.3501 [LOGO] ATLAS CAPITAL SERVICES, INC. Atlas Capital Services shall contribute to the Claim for which such indemnify is held unavailable in such proportion as is appropriate to reflect the relative benefits to us, on the one hand, and Atlas Capital Services on the other, in connection with Atlas Capital Services' engagement referred to above, and the relative fault, as between us and the Indemnified Person in respect of the Claim, subject to the limitation that in no event shall the amount of Atlas Capital Services' contribution to such Claim exceed the amount of fees actually received by Atlas Capital Services from us pursuant to Atlas Capital Services' engagement. We hereby agree that the relative benefits to us, on the one hand, and Atlas Capital Services on the other, with respect to Atlas Capital Services' engagement shall be deemed to be in the same proportion as (a) the total value paid or proposed to be paid or received by us or our stockholders as the case may be, pursuant to the transaction (whether or not consummated) for which you are engaged to render services bears to (b) the fee actually paid to Atlas Capital Services in connection with such engagement; provided, however, that under no circumstances whatsoever shall Atlas Capital Services be required to contribute to any such claim any amount in excess of the fee actually paid in connection with such engagement. Our indemnity, reimbursement and contribution obligations under this Agreement shall be in addition to, and shall in no way limit or otherwise adversely affect, any rights that any Indemnified Party may have at law or at equity. We hereby consent to personal junction and service of process and venue in any court in the State of New York in which any claim for indemnity is brought by and Indemnified Person.
