In case at any time on or after the date hereof, the Company shall declare any dividend, or authorize any other distribution, upon any stock of the Company of any class, payable in Additional Shares of Common Stock or by the issuance of Convertible Securities, such declaration or distribution shall be deemed to have been issued or sold (as of the record date) without consideration.

After any such dissolution, liquidation or winding up which shall result in any cash distribution in excess of the Exercise Price provided for by this Warrant, the Warrantholders may, at each such Warrantholder's option, exercise the same without making payment of the Exercise Price, and in such case the Company shall, upon the distribution to said Warrantholders, consider that said Exercise Price has been paid in full to it and in making settlement to said Warrantholders, shall deduct from the amount payable to such Warrantholders an amount equal to such Exercise Price.

(iii) Each party entitled to indemnification hereunder (the "Indemnified Party") shall give notice to the party required to provide indemnification (the "Indemnifying Party") promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party (at such Indemnifying Party's expense) to assume the defense of any claim or any litigation resulting therefrom, provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or litigation, shall be reasonably satisfactory to the Indemnified Party, and the Indemnified Party may participate in such defense at such party's expense, and provided further, that the omission by any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Section 11(f) except to the extent that the omission results in a failure of actual notice to the Indemnifying Party and such Indemnifying Party, in the defense of any 13 such claim or litigation, shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation. (iv) If the indemnification provided for in this Section 11(f) is unavailable or insufficient to hold harmless an Indemnified Party in respect of any losses, claims, damages, liabilities, expenses or actions in respect thereof referred to herein, then the Indemnifying Party shall contribute to the amount paid or payable by such Indemnified Party as a result of such losses, claims, damages, liabilities, expenses or actions in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party on the one hand, and the Indemnified Party on the other, in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities, expenses or actions as well as any other relevant equitable considerations, including the failure to give the notice required hereunder. The relative fault of the Indemnifying Party and the Indemnified Party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact relates to information supplied by the Indemnifying Party or the Indemnified Party and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Warrantholders agree that it would not be just and equitable if contributions pursuant to this Section 11(f) were determined by pro rata allocation or by any other method of allocation which did not take account of the equitable considerations referred to above. The amount paid or payable to an Indemnified Party as a result of the losses, claims, damages, liabilities or actions in respect thereof, referred to above, shall be deemed to include any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating or defending any such action or claim. Notwithstanding the contribution provisions of this Section 11(f), in no event shall the amount contributed by any seller of Registrable Stock exceed the aggregate net offering proceeds received by such seller from the sale of Registrable Stock to which such contribution or indemnification claim relates. No person guilty of fraudulent misrepresentations (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who is not guilty of such fraudulent misrepresentation. (v) The indemnification required by this Section 11(f) shall be made by periodic payments during the course of the investigation or defense, as and when bills are received or expenses incurred. Anything contained herein to the contrary notwithstanding, the liability of any holder of Registrable Stock under this Section 11(f) shall not exceed the amount of the net proceeds actually received by such holder from the sale of its Registrable Stock pursuant to the registration, qualification, notification or compliance in respect of which such liability arose. 14 (g) Reporting Requirements Under Exchange Act. The Company shall maintain the registration of its Common Stock under Section 12 of the Exchange Act and shall keep effective such registration and shall timely file such information, documents and reports the Commission may require or prescribe under Section 13 of the Exchange Act, or otherwise.
