Item 4.     Description of the Securities

Not applicable.

Item 5.     Interests of Named Experts and Counsel

Not applicable.

Item 6.     Indemnification of Directors and Officers

Bye-Law 145 of Aspen’s bye-laws provides, among other things, that, subject to certain provisos, Aspen’s directors, officers or any other person appointed to a committee of the board of directors and any resident representative (and their respective heirs, executors or administrators; collectively, the ‘‘Indemnified Persons’’) shall be indemnified and held harmless out of the assets of Aspen against all liabilities, loss, damage or expense (including but not limited to liabilities under contract, tort and statute or any applicable foreign law or regulation and all reasonable legal and other costs and expenses properly payable) incurred or suffered by him by reason of any act done, conceived in or omitted in the conduct of Aspen’s business or in the discharge of his duties and the indemnity contained in Bye-Law 145 shall extend to the Indemnified Persons of Aspen acting in any office or trust in the reasonable belief that he has been appointed or elected to such office or trust notwithstanding any defect in such appointment or election provided always that the indemnity contained in Bye-Law 145 shall not extend to any matter which would render it void under the Bermuda Companies Act 1981, as amended (the ‘‘Companies Act’’).

Bye-Law 149 of Aspen’s bye-laws provides that each shareholder and Aspen agree to waive any claim or right of action he or it may at any time have, whether individually or by or in the right of Aspen, against any director or officer of Aspen on account of any action taken by such director or officer or the failure of such director or officer to take any action in the performance of his duties with or for Aspen, provided, however, that such waiver shall not apply to any claims or rights of action arising out of the fraud of such director or officer or to recover any gain, personal profit or advantage to which such director or officer is not legally entitled.

The Companies Act provides that a Bermuda company may indemnify its directors in respect of any loss arising or liability attaching to them as a result of any negligence, default, breach of duty or breach of trust of which they may be guilty. However, the Companies Act also provides that any provision, whether contained in Aspen’s bye-laws or in a contract or arrangement between Aspen and the director, indemnifying such director against any liability which would attach to him in respect of his fraud or dishonesty will be void.

Aspen has purchased directors and officers liability insurance policies. Such insurance will be available to Aspen’s directors and officers in accordance with its terms. In addition, certain directors may be covered by directors and officers liability insurance policies purchased by their respective employers, subject to the limitation of the policy terms.

Item 7.     Exemption From Registration Claimed

Not applicable.

Item 9.     Undertakings

(a)	The undersigned Registrant hereby undertakes:

	(1)	to file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:

	(i)	to include any prospectus required by Section 10(a)(3) of the Securities Act;

	(ii)	to reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the ‘‘Calculation of Registration Fee’’ table in the effective Registration Statement; and

	(iii)	to include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material change to such information in this Registration Statement;

provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in this Registration Statement;

	(2)	that, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; and

	(3)	to remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b)

The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the undersigned Registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act that is incorporated by reference into this Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c)

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
