                               EXPLANATORY NOTE

This Post-Effective Amendment No. 2 (the "Amendment") to this Registration
Statement on Form N-14 (the "Registration Statement"), under the Securities Act
of 1933 is being filed by Loomis Sayles Funds II (the "Registrant") solely for
the purpose of adding the enclosed exhibits to this Registration Statement.

Parts A and B of Post-Effective Amendment No. 1 to the Registration Statement
filed with the Securities and Exchange Commission on August 29, 2007 (Accession
No. 0001193125-07-191842) are incorporated herein by reference.



                                                               Registration No.
                                                                     333-144327

                                    PART C
                               OTHER INFORMATION

Item 15. Indemnification

   Under Article 5 of the Registrant's By-laws, any past or present Trustee or
officer of the Registrant (hereinafter referred to as a "Covered Person") shall
be indemnified to the fullest extent permitted by law against all liability and
all expenses reasonably incurred by him or her in connection with any claim,
action, suit or proceeding to which he or she may be a party or otherwise
involved by reason of his or her being or having been a Covered Person. That
provision does not authorize indemnification when it is determined that such
Covered Person would otherwise be liable to the Registrant or its shareholders
by reason of willful misfeasance, bad faith, gross negligence or reckless
disregard of his or her duties. This description is modified in its entirety by
the provision of Article 5 of the Registrant's By-laws incorporated by
reference to exhibit (b)(1) to Post-Effective Amendment No. 39 to the
Registrant's Registration Statement filed on December 2, 2005.

   The Distribution Agreement, the Custodian Contract, the Transfer Agency and
Service Agreement and the Administrative Services Agreement (the "Agreements")
contained herein and in various post-effective amendments and incorporated
herein by reference, provide for indemnification. The general effect of these
provisions is to indemnify entities contracting with the Registrant against
liability and expenses in certain circumstances. This description is modified
in its entirety by the provisions of the Agreements as contained in this
Registration Statement and incorporated herein by reference.

   Insofar as indemnification for liabilities arising under the Securities Act
of 1933, as amended (the "Securities Act"), may be permitted to Trustees,
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 Securities and Exchange 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 Trustee,
officer or controlling person of the Registrant in connection with the
successful defense of any claim, action, suit or proceeding) is asserted
against the Registrant by such Trustee, officer or controlling person in
connection with the shares 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.

                                      1



Registrant and its Trustees, officers and employees are insured, under a policy
of insurance maintained by the Registrant in conjunction with Natixis Global
Asset Management, L.P. (formerly IXIS Asset Management U.S. Group, L.P.) and
its affiliates, within the limits and subject to the limitations of the policy,
against certain expenses in connection with the defense of actions, suits or
proceedings, and certain liabilities that might be imposed as a result of such
actions, suits or proceedings, to which they are parties by reason of being or
having been such Trustees or officers. The policy expressly excludes coverage
for any Trustee or officer for any claim arising out of any fraudulent act or
omission, any dishonest act or omission or any criminal act or omission of the
Trustee or officer.
