(b) All underwriting discounts and commissions incurred in connection with registrations shall be paid by the Stockholder. 7. Indemnification. Conrex shall indemnify and hold harmless the Company and each officer, director or control person of any such entity, who is or may be a party or is or may be threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of or arising from (i) any actual or alleged misrepresentation or misstatement of facts or omission to represent or state facts made or alleged to have been made by Conrex to the Company, (or its agents or representatives), or omitted or alleged to have been omitted by Conrex, concerning Conrex, or Conrex's authority to invest or financial position in connection with the offering or sale of the Shares in this Agreement, in the Subscription Agreement or elsewhere, or (ii) any breach of warranty or failure to comply with any covenant contained in this Agreement or in the Subscription Agreement, including, without limitation, any such misrepresentation, misstatement or omission, or breach of any warranty or covenant, contained herein or any other document submitted by Conrex, against losses, liabilities and expenses for which the Company, or its officers, directors or control persons has not otherwise been reimbursed (including attorneys' fees, judgments, fines and amounts paid in settlement in matters settled in accordance with the provision of the following paragraph) incurred by the Company, or such officer, director or control person in connection with such action, suit or proceeding; provided, however, that Conrex will not be liable in any such case for losses, claims, damages, liabilities or expenses that a court of competent jurisdiction shall have found in a final judgment to have arisen -5- primarily from the gross negligence or willful misconduct of the Company or the party claiming a right to indemnification. In case any proceeding shall be instituted involving any person with respect to whom indemnity may be sought, such person (the "Indemnified Party") shall promptly notify Conrex, and Conrex, upon the request of the Indemnified Party, shall retain counsel reasonably satisfactory to the Indemnified Party to represent the Indemnified Party and any others Conrex may designate in such proceedings and shall pay as incurred the fees and expenses of such counsel related to such proceeding. In any such proceeding, any Indemnified Party shall have the right to retain its own counsel at its own expense, except that Conrex shall pay as incurred the fees and expenses of counsel retained by the Indemnified Party in the event that (i) Conrex and the Indemnified Party shall have mutually agreed to the retention of such counsel or, (ii) the named parties to any such proceeding (including any impleaded parties) include both Conrex and the Indemnified Party and representation of both parties by the same counsel would be inappropriate, in the reasonable opinion of the Indemnified Party, due to actual or potential differing interests between them. Conrex shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, Conrex agrees to indemnify the Indemnified Party to the extent set forth in this Agreement. In the event a claim for indemnification as described herein is determined to be unenforceable by a final judgment of a court of competent jurisdiction, then Conrex shall contribute to the aggregate losses, claims, damages or liabilities to which the Company or its officers, directors, agents, employees or controlling persons may be subject in such amount as is appropriate to reflect the relative benefits received by each of the undersigned and the party seeking contribution on the one hand and the relative faults of Conrex and the party seeking contribution on the other, as well as any relevant equitable considerations. The provisions of this Agreement relating to indemnification and contribution shall survive termination of this Agreement and shall be binding upon any successors or assigns of Conrex. 8. Termination of Registration Rights. The rights granted pursuant to this Agreement shall terminate as to the Stockholder upon the occurrence of any of the following: (a) all of the Registrable Securities have been registered; or (b) all of the Registrable Securities may be sold without such registration pursuant to Rule 144. 9.
