this Policy, but in the event of such failure, the Insurer will only be liable to the same extent as if the "Underlying Policies" remained in full force and effect.

E. PAYMENT OF PREMIUM

The First Named Insured listed in Item 1. of the Declarations Page of this Policy shall be responsible for and act on behalf of all Insureds with respect to the payment of any premiums due under this Policy.

F. REQUIRED NOTICES TO INSURER BY THE INSURED

1. Notice of Occurrence, Offense, Claim or Suit

The Insured shall give written notice to the Insurer of any occurrence, offense, claim or suit likely to involve this Policy as soon as practicable.

2. Notice Regarding "Underlying Policies"

The Insured shall give written notice to the Insurer as soon as practicable after an Insured has become aware of any "Followed Underlying Policy(ies)" being cancelled or non-renewed or otherwise ceasing to be in effect.

With respect to the notice required in Paragraphs 1 and 2 of this Condition F., notice to an "Underlying Insurer" shall not constitute notice to the Insurer of this Policy. Notice under this Condition F. shall be given to the Insurer at the appropriate address set forth in Item 7. of the Declarations Page of this Policy.

G. UNIMPARED UNDERLYING LIMITS OF LIABILITY

The Insured warrants that the Total Scheduled Underlying Insurance Aggregate, as listed in Item 5. of the Declarations Page of this Policy, shall be unimpaired as of the effective date of this Policy. In the event such underlying aggregate limits of liability are impaired as of the effective date of this Policy, this Policy shall apply as if such aggregate limits of liability were unimpaired. In the event of non-concurrent policy periods between this Policy and "Underlying Policies", only occurrences or claims that would be covered during the Policy Period of this Policy shall be considered in determining the extent of any reduction or exhaustion of the underlying aggregate limits of liability, and the Insured shall retain liability for any resulting gap in coverage.

H. BANKRUPTCY OR INSOLVENCY

The Insured's bankruptcy or insolvency will not relieve us from the payment of claims covered by this policy. In the event of the bankruptcy, insolvency, inability or unwillingness of any "Underlying Insurer" to pay claims covered by "Scheduled Underlying Insurance" we will be liable only to the same extent we would have been liable had the "Underlying Policies" been applicable and collectible.

I. SERVICE OF SUIT

It is agreed that in the event of our failure to pay any amount claimed to be due hereunder, we, at the request of the Insured, will submit to jurisdiction of a court of competent jurisdiction within the United States. Nothing in this condition constitutes or should be understood to constitute a waiver of our rights to commence an action in any court of competent jurisdiction in the United States, to remove an action to a United States District Court or to seek a transfer of a case to another court as permitted by the laws of the United States or any state in the United States. It is further agreed that service of process may be made upon Counsel, Legal Department, National Liability & Fire Insurance Company, 3024 Harney Street, Omaha NE, 68131 or his or her representative, and that in any suit instituted against us, upon this policy, we will abide by the final decision of such court or of an appellate court in the event of an appeal.

Further, pursuant to any statute of any state, territory, or district of the United States which makes provision therefore, we hereby designate the Superintendent, Commissioner, Director of Insurance, or other officer specified for that purpose in the statute, or his or her successor or successors in office as our true and lawful attorney upon whom may be served any lawful process in any action, suit or proceeding instituted by or on behalf of the Insured or any beneficiary hereunder arising out of this contract of insurance, and hereby designate the Counsel, Legal Department, National Liability & Fire Insurance Company, 3024 Harney Street, Omaha NE, 68131, as the person to whom the said officer is authorized to mail such process or a true copy thereof.
