Section 3. Claims.

If a claim for indemnification following the final disposition of such Proceeding by a Covered Person or advancement of expenses by a Covered Person under this Article VII is not paid in full within thirty (30) days after a written claim therefor by the Covered Person or, in the case of advancement of expenses, a statement or statements requesting such amounts to be advanced, has been received by the Corporation, the Covered Person may thereupon (but not before) file suit to recover the unpaid amount of such claim and, if successful in whole or in part, shall be entitled to be paid the expense of prosecuting such claim. In any such action the Corporation shall have the burden of proving that the Covered Person is not entitled to the requested indemnification or advancement of expenses under applicable law.

Section 4. Nonexclusivity of Rights.
