         6.1 During the term of this Agreement, LICENSEE will pay to LICENSOR as

agrees to pay to LICENSOR during the Contract Period annual minimum Royalties
("Minimum Royalties") as follows:

             Contract Year                       Minimum Royalties

If the sum of the total Royalties paid with respect to a Contract Year do not
equal or exceed the Minimum Royalties for such Contract Year, the difference
between the Minimum Royalties and the Royalties for such Contract Year shall be
due and payable thirty (30) days following the end of such Contract Year.

         6.3 If upon the expiration of the initial Contract Period, LICENSOR in
its sole and absolute discretion elects to renew this Agreement as hereinafter
provided for an additional five (5) year term, the Minimum Royalties for the
first renewal period shall be the greater of the following:

(including, but not limited to, advertising, promotional, packaging and wrapping
material and any other such material wherein the Licensed Trademarks may
appear), the appropriate trademark and/or copyright notices, as shall be
designated in writing in advance by LICENSOR. LICENSEE agrees to deliver to
LICENSOR upon request, free of cost, samples of each Licensed Product together

LICENSOR.

such become known to LICENSEE and shall provide LICENSOR with any available
evidence of such infringement. Only LICENSOR shall have the right to commence
legal proceedings against such infringer, and the expense of such legal

expense, shall make available to LICENSOR any relevant books, records, papers,
information, designs, samples, specimens, and the like and shall cause any of
the LICENSEE's employees to be deposed or to testify, whenever requested to do
so by LICENSOR. Any damage award or recovery resulting from such legal
proceedings shall be divided equally between LICENSOR and LICENSEE.


10.      INDEMNIFICATION AND INSURANCE.

         10.1 LICENSEE agrees to protect, indemnify and save harmless LICENSOR,
its parent, subsidiaries and affiliates and all officers, directors, agents,
employees and representatives thereof, and any of them, from and against any and

including reasonable attorneys fees, arising out of, or in any way connected
with, any claim or action for the violation by LICENSEE of any statutory or
regulatory obligation, any claim or action for injury or damage to property,
personal injury, death or other cause of action involving alleged defects in
Licensed Products, and any other claim or action arising out of LICENSEE's
activities pursuant to this Agreement or other conduct of its business.

         10.2 LICENSEE shall, within thirty (30) calendar days after the
execution of this Agreement, obtain from an insurance company reasonably
acceptable to LICENSOR, and maintain during the term of this Agreement and for a
period of twenty-four (24) months following the expiration or termination of
this Agreement, public and products liability insurance with a limit of
liability of not less than Five Million ($5,000,000) U.S. dollars per occurrence

charged because of damage or injuries suffered by any servants, agents,
contractors, employees or customers of LICENSEE or by the general public,
resulting from the use or sale of the Licensed Products manufactured,
distributed, advertised or sold by LICENSEE or by LICENSEE's contractor.
LICENSEE agrees to cause LICENSOR's name to be entered in such policy as an
additional named insured and an additional loss payee, and to deliver to
LICENSOR a certificate thereof. Said insurance shall provide that it cannot be
canceled without the insurer first giving LICENSOR twenty (20) calendar days'
advance written notice thereof. LICENSEE shall furnish or cause to be furnished
to LICENSOR evidence of the maintenance and renewal of the insurance required
herein, including, but not limited to, copies of policies, certificates of

         11.1 In the event of a default by either party in the performance of
any of its obligations pursuant to this Agreement, the non-defaulting party
shall give written notice of such default to the defaulting party. Within thirty
(30) days of its receipt of such notice, the defaulting party shall cure the
default. If the defaulting party does not take such corrective actions or cure
the default within the respective time period, the non-defaulting party shall
have the right to terminate this Agreement upon the expiration of the respective
period. The right to remedy a default shall not apply to a violation of Sections
4, 5, 6 or 7 of this Agreement, which shall give LICENSOR the right, in its sole
discretion, to treat as such violation a non-curable default and to terminate
this Agreement.

         11.2 Either party shall have the right to terminate this Agreement upon
ten (10) days prior notice upon the occurrence of any of the following events:

              (a)      If the other party shall become insolvent or shall
                       make an assignment for the benefit of creditors or
                       become the subject of receivership, bankruptcy or
                       other insolvency or debtor relief proceedings, or any
                       similar proceedings;

              (b)      If the other party shall cease to do business; or

              (c)      Except as permitted under Section 14 hereof, if the
                       other party shall attempt to assign any of its rights
                       under this Agreement.

         A party's exercise of its right, pursuant to this Section 11.2, to
terminate this Agreement shall be without prejudice to any other legal or
equitable remedy such party may hold against the other party by reason of the
other party's breach of any term or condition of this Agreement.

         11.3 No assignee for the benefit of creditors, receiver, liquidator,
trustee in bankruptcy, sheriff or any other officer of the court or official
charged with taking over custody of LICENSEE's assets or business, shall have
any right to continue performance of this Agreement, and this Agreement may not
be assigned by operation of law.

         11.4 Failure to terminate this Agreement pursuant to this Section 11
shall not effect or constitute a waiver of any remedies the non-defaulting party
would have been entitled to demand, whether by way of damages, termination or
otherwise. Termination of this Agreement shall be without prejudice to the
rights and liabilities of either party to the other in respect of any matter
arising under this Agreement.
