Item 26. Persons Controlled by or Under Common Control with the Depositor or Registrant

Incorporated herein by reference to Item 26 in Post-Effective Amendment No. 10 to Registration
Statement on Form N-4 for Variable Annuity Account C of ING Life Insurance and Annuity Company
(File No. 333-105479), as filed with the Securities and Exchange Commission on April 11, 2008.

Item 27. Number of Contract Owners

As of July 31, 2008, there were 3,472 individuals holding interests in variable annuity contracts funded
through Variable Annuity Account I of ING Life Insurance and Annuity Company.

Item 28. Indemnification

Section 33-779 of the Connecticut General Statutes (“CGS”) provides that a corporation may provide
indemnification of or advance expenses to a director, officer, employee or agent only as permitted by
Sections 33-770 to 33-778, inclusive, of the CGS. Reference is hereby made to Section 33-771(e) of the
CGS regarding indemnification of directors and Section 33-776(d) of CGS regarding indemnification of
officers, employees and agents of Connecticut corporations. These statutes provide in general that
Connecticut corporations incorporated prior to January 1, 1997 shall, except to the extent that their
certificate of incorporation expressly provides otherwise, indemnify their directors, officers, employees
and agents against “liability” (defined as the obligation to pay a judgment, settlement, penalty, fine,
including an excise tax assessed with respect to an employee benefit plan, or reasonable expenses
incurred with respect to a proceeding) when (1) a determination is made pursuant to Section 33-775 that
the party seeking indemnification has met the standard of conduct set forth in Section 33-771 or (2) a
court has determined that indemnification is appropriate pursuant to Section 33-774. Under Section 33-
775, the determination of and the authorization for indemnification are made (a) by two or more
disinterested directors, as defined in Section 33-770(3); (b) by special legal counsel; (c) by the
shareholders; or (d) in the case of indemnification of an officer, agent or employee of the corporation, by
the general counsel of the corporation or such other officer(s) as the board of directors may specify. Also,
Section 33-772 with Section 33-776 provide that a corporation shall indemnify an individual who was
wholly successful on the merits or otherwise against reasonable expenses incurred by him in connection
with a proceeding to which he was a party because he is or was a director, officer, employee, or agent of
the corporation. Pursuant to Section 33-771(d), in the case of a proceeding by or in the right of the

corporation or with respect to conduct for which the director, officer, agent or employee was adjudged
liable on the basis that he received a financial benefit to which he was not entitled, indemnification is
limited to reasonable expenses incurred in connection with the proceeding against the corporation to
which the individual was named a party.

Section 33-777 of the statute does specifically authorize a corporation to procure indemnification
insurance on behalf of an individual who is or was a director of the corporation. Consistent with the
statute, ING America Insurance Holdings, Inc. maintains a Professional Liability umbrella insurance
policy issued by an international insurer. The policy covers ING America Insurance Holdings, Inc. and
any company in which ING America Insurance Holdings, Inc. has a controlling interest of 50% or more.
This would encompass the principal underwriter as well as the depositor. Additionally, the parent
company of ING America Insurance Holdings, Inc., ING Groep N.V., maintains an excess umbrella cover
with limits in excess of $125,000,000. The policy provides for the following types of coverage: errors
and omissions/professional liability, directors and officers, employment practices, fiduciary and fidelity.

Section 20 of the ING Financial Advisers, LLC Limited Liability Company Agreement executed as of
November 28, 2000 provides that ING Financial Advisers, LLC will indemnify certain persons against
any loss, damage, claim or expenses (including legal fees) incurred by such person if he is made a party
or is threatened to be made a party to a suit or proceeding because he was a member, officer, director,
employee or agent of ING Financial Advisers, LLC, as long as he acted in good faith on behalf of ING
Financial Advisers, LLC and in a manner reasonably believed to be within the scope of his authority. An
additional condition requires that no person shall be entitled to indemnity if his loss, damage, claim or
expense was incurred by reason of his gross negligence or willful misconduct. This indemnity provision
is authorized by and is consistent with Title 8, Section 145 of the General Corporation Law of the State of
Delaware.

Item 29. Principal Underwriter

(a) In addition to serving as the principal underwriter for the Registrant, ING Financial Advisers, LLC
also acts as the principal underwriter for ING Partners, Inc. (a management investment company
registered under the Investment Company Act of 1940 (1940 Act)). Additionally, ING Financial
Advisers, LLC acts as the principal underwriter for Variable Life Account B of ING Life Insurance
and Annuity Company (ILIAC), Variable Life Account C of ILIAC, Variable Annuity Account C
of ILIAC, Variable Annuity Account I of ILIAC and Variable Annuity Account G of ILIAC
(separate accounts of ILIAC registered as unit investment trusts under the 1940 Act). ING
Financial Advisers, LLC is also the principal underwriter for (i) Separate Account N of ReliaStar
Life Insurance Company (RLIC) (a separate account of RLIC registered as a unit investment trust
under the 1940 Act.), (ii) ReliaStar Select Variable Account of ReliaStar Life Insurance Company
(a separate account of RLIC registered as a unit investment trusts under the 1940 Act), (iii) MFS
ReliaStar Variable Account (a separate account of RLIC registered as a unit investment trusts under
the 1940 Act), (iv) Northstar Variable Account (a separate account of RLIC registered as a unit
investment trusts under the 1940 Act) (v) ReliaStar Life Insurance Company of New York Variable
Annuity Funds A, B, C (a management investment company registered under the 1940 Act), (vi)
ReliaStar Life Insurance Company of New York Variable Annuity Funds D, E, F, G, H, I (a
management investment company registered under the 1940 Act), (vii) ReliaStar Life Insurance
Company of New York Variable Annuity Funds M, P, and Q (a management investment company

06095-4774 and at ING Americas at 5780 Powers Ferry Road, Atlanta, Georgia 30327-4390.

Item 31. Management Services

Not applicable

Item 32. Undertakings

Registrant hereby undertakes:

(a)	to file a post-effective amendment to this registration statement on Form N-4 as frequently as is
	necessary to ensure that the audited financial statements in the registration statement are never
	more than sixteen months old for as long as payments under the variable annuity contracts may
	be accepted;
(b)	to include as part of any application to purchase a contract offered by a prospectus which is part
	of this registration statement on Form N-4, a space that an applicant can check to request a
	Statement of Additional Information; and
(c)	to deliver any Statement of Additional Information and any financial statements required to be
	made available under this Form N-4 promptly upon written or oral request.

The Company hereby represents that it is relying upon and complies with the provisions of Paragraphs (1)
through (4) of the SEC Staff’s No-Action Letter dated November 28, 1988 with respect to language
concerning withdrawal restrictions applicable to plans established pursuant to Section 403(b) of the
Internal Revenue Code. See American Counsel of Life Insurance; SEC No-Action Letter, [1988 WL
1235221 *13 (S.E.C.)]

Insofar as indemnification for liability arising under the Securities Act of 1933 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 Securities and Exchange Commission
such indemnification is against public policy as expressed in the 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
of whether such indemnification by it is against public policy as expressed in the Act and will be
governed by the final adjudication of such issue.

ING Life Insurance and Annuity Company represents that the fees and charges deducted under the
contracts covered by this registration statement, in the aggregate, are reasonable in relation to the services
rendered, the expenses expected to be incurred, and the risks assumed by the insurance company.
