(i) If any third party shall notify the Indemnitee with respect to any matter (a "Third Party Claim") which may give rise to a claim for indemnification under this Section 9, then the Indemnitee shall promptly notify the Indemnitor thereof in writing; provided, however, that no delay on the part of the Indemnitee in notifying the Indemnitor shall relieve the Indemnitor from any obligation hereunder unless (and then solely to the extent) the Indemnitor thereby is prejudiced. 26 (ii) The Indemnitor will have the right to defend the Indemnitee against the Third Party Claim with counsel of its choice reasonably satisfactory to the Indemnitee so long as (A) it notifies the Indemnitee in writing within 15 days after the Indemnitee has given notice of the Third Party Claim that the Indemnitor will indemnify the Indemnitee from and against the entirety of any Adverse Consequences the Indemnitee may suffer resulting from, arising out of, relating to, in the nature of, or caused by the Third Party Claim, (B) the Indemnitor provides the Indemnitee with evidence acceptable to the Indemnitee that the Indemnitor will have the financial resources to defend against the Third Party Claim and fulfill its indemnification obligations hereunder, (C) settlement of, or an adverse judgment with respect to, the Third Party Claim is not, in the good faith judgment of the Indemnitee, likely to establish a precedential custom or practice adverse to the continuing business interests of the Indemnitee, and (D) the Indemnitor conducts the defense of the Third Party Claim actively and diligently. (iii) So long as the Indemnitor is conducting the defense of the Third Party Claim in accordance with Section 9(c)(ii) above, (A) the Indemnitee may retain separate co-counsel at its sole cost and expense and participate in the defense of the Third Party Claim, (B) the Indemnitee will not consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim without the prior written consent of the Indemnitor (not to be withheld unreasonably), and (C) the Indemnitor will not consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim without the prior written consent of the Indemnitee, not to be unreasonably withheld. (iv) In the event any of the conditions in Section 9(c)(ii) above is or becomes unsatisfied, however, (A) the Indemnitee may defend against, and consent to the entry of any judgment or enter into any settlement with respect to, the Third Party Claim in any manner it may deem appropriate (and the Indemnitee need not consult with, or obtain any consent from, the Indemnitor in connection therewith), (B) the Indemnitor will reimburse the Indemnitee promptly and periodically for the costs of defending against the Third Party Claim (including attorneys' fees and expenses), and (C) the Indemnitor will remain responsible for any Adverse Consequences the Indemnitee may suffer resulting from, arising out of, relating to, in the nature of, or caused by the Third Party Claim to the fullest extent provided in this Section 9. (d) Determination of Adverse Consequences. The Parties shall take into account the time cost of money (using the Applicable Rate as the discount rate) in determining Adverse Consequences for purposes of this Section 9. All indemnification payments under this Section 9 shall be deemed adjustments to the Purchase Price. (e) Recoupment Under the Note. In the event that the Purchaser shall suffer Adverse Consequences for which indemnification pursuant to the foregoing provisions shall be payable by the Sellers and the Sellers shall not make any such indemnification payment within sixty (60) days after such indemnity amount shall become payable, the Purchaser shall have the option of recouping all or any part of any Adverse Consequences it may suffer by notifying the Sellers that the Purchaser is offsetting the amount of such Adverse Consequences against the principal amount outstanding under the Note. An offset pursuant to this subsection shall affect the timing and amount of payments required under the Note in the same manner as if the Purchaser had made a permitted prepayment (without premium or penalty) thereunder. 27 (f) Other Indemnification Provisions. The foregoing indemnification provisions are in addition to, and not in derogation of, any statutory, equitable, or common law remedy any Party may have for breach of representation, warranty, or covenant. The Sellers hereby agree that they will not make any claim for indemnification against the Corporation by reason of the fact that they were directors, officers, employees, or agents of the Corporation or were serving at the request thereof as a partner, trustee, director, officer, employee, or agent of another entity (whether such claim is for judgments, damages, penalties, fines, costs, amounts paid in settlement, losses, expenses, or otherwise and whether such claim is pursuant to any statute, charter document, bylaw, agreement, or otherwise) with respect to any action, suit, proceeding, complaint, claim, or demand brought by the Purchaser against the Sellers (whether such action, suit, proceeding, complaint, claim, or demand is pursuant to this Agreement, applicable law, or otherwise). 10. TERMINATION. (a) Termination of Agreement. Certain of the Parties may terminate this Agreement as provided below: (i) the Purchaser and the Sellers may terminate this Agreement by mutual written consent at any time prior to the Closing; (ii) the Purchaser may terminate this Agreement by giving written notice to the Sellers at any time prior to the Closing (A) in the event any of the Sellers has breached any material representation, warranty, or covenant contained in this Agreement in any material respect, the Purchaser has notified the Seller of the breach, and the breach has continued without cure for a period of 10 days after the notice of breach or (B) if the Closing shall not have occurred on or before October 1, 1996, by reason of the failure of any condition precedent under Section 7(a) hereof (unless the failure results primarily from the Purchaser itself breaching any representation, warranty, or covenant contained in this Agreement); and (iii) the Sellers may terminate this Agreement by giving written notice to the Purchaser at any time prior to the Closing (A) in the event the Purchaser has breached any material representation, warranty, or covenant contained in this Agreement in any material respect, any of the Sellers has notified the Purchaser of the breach, and the breach has continued without cure for a period of 10 days after the notice of breach or (B) if the Closing shall not have occurred on or before November 1, 1996 by reason of the failure of any condition precedent under Section 7(b) hereof (unless the failure results primarily from any of the Sellers themselves breaching any representation, warranty, or covenant contained in this Agreement).

(b) Arbitration of Disputes; Legal Fees. Any dispute arising under this Stock Purchase Agreement shall be submitted by the parties to binding arbitration pursuant to the Florida Uniform Arbitration Act, with any such arbitration proceeding being conducted in accordance with the rules of the American Arbitration Corporation.

Each of the Parties submits to the jurisdiction of any state or federal court sitting in Ft. Lauderdale, Broward County, Florida for purposes of enforcement of any arbitration award hereunder. Each Party also agrees not to bring any action or proceeding arising out of or relating to this Agreement in any other court. Each of the Parties waives any defense of inconvenient forum to the maintenance of any action or proceeding so brought and waives any bond, surety, or other security that might be required of any other Party with respect thereto.

(k) Amendments and Waivers. No amendment of any provision of this Agreement shall be valid unless the same shall be in writing and signed by the Purchaser and the Sellers. No waiver by any Party of any default, misrepresentation, or breach of warranty or covenant hereunder, whether intentional or not, shall be deemed to extend to any prior or subsequent default, misrepresentation, or breach of warranty or covenant hereunder or affect in any way any rights arising by virtue of any prior or subsequent such occurrence.

If any Party has breached any representation, warranty, or covenant contained herein in any respect, the fact that there exists another representation, warranty, or covenant relating to the same subject matter (regardless of the relative levels of specificity) which the Party has not breached shall not detract from or mitigate the fact that the Party is in breach of the first representation, warranty, or covenant.
