LICENSEE and the manner in which such Royalties were determined.

         7.2 LICENSEE shall deliver to LICENSOR with each quarterly payment a

they may be reasonably required by LICENSOR’s accountants in order to verify the

figures reported in any statements furnished to LICENSOR pursuant to this

Section 7. Such books of account and records shall be made available to LICENSOR

and its accountants at LICENSEE’s office located as herein stated or such other

place as the parties shall mutually agree. LICENSEE shall render all possible

assistance to LICENSOR and its accountants for the purpose of facilitating the

checking or auditing of net sales and of the figures set forth in any of

LICENSEE’s statements. If the examination or audit reveals the underpayment of

any Royalties, LICENSEE shall immediately pay LICENSOR the amount of the

deficiency with interest, and if the deficiency exceeds five percent (5%) of the

amount of Royalties paid with respect to such year or years audited, LICENSEE

shall pay the cost of the examination or audit.

by others of the Licensed Trademarks on articles similar to the Licensed

Products if and when 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

proceedings shall be shared equally by LICENSOR and LICENSEE. In any

infringement action, proceeding or claim brought by LICENSOR, LICENSEE, at its

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

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

this Agreement.

                       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

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.

item whatsoever in connection with the Licensed Trademarks. It is further agreed

that following expiration of the Contract Period, LICENSEE shall not

manufacture, advertise, promote, distribute or sell any item whatsoever in

connection with the use of any name, figure, design, logo, trademark or trade
