(including attorneys&#146; fees) and other amounts paid in settlement actually and reasonably incurred
by them in connection with any threatened, pending or completed action, suit or proceeding, whether
civil, criminal, administrative or investigative, in which any such person was or is a party or is
threatened to be made a party. The right to indemnification includes the right to be paid the
expenses incurred in defending or investigating a threatened or pending action, suit or proceeding
in advance of the final disposition of such action, suit or proceeding; provided that, if required
by Delaware law, payment of expenses in advance to an officer or director shall be conditioned upon
receipt by the Company of an undertaking by or on behalf of such director or officer to repay such
amount if it is ultimately determined that he is not entitled to indemnification. The advancement
of expenses, as well as indemnification, pursuant to the Bylaws of the Company is not exclusive of
any other rights which persons seeking indemnification or advancement of expenses from the Company
may have. The Company also maintains an insurance policy pursuant to which its directors and
officers are insured against certain liabilities that might arise out of their relationship with
the Company as directors and officers.

permitted to directors, officers and controlling persons of the Company pursuant to the foregoing
provisions, or otherwise, the Company 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 Company of expenses incurred or paid by a director, officer or
controlling person of the Company 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 Company 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 Act and will be governed by the
final adjudication of such issue.

PART II
INFORMATION REQUIRED IN REGISTRATION STATEMENT
Item 3. Incorporation of Documents by Reference
The following
documents, which IndyMac Bancorp, Inc. (the "Company") or the Plan previously filed with the
Securities and Exchange Commission (the "Commission") pursuant to the Securities Exchange Act of
1934, as amended (the "Exchange Act"), are hereby incorporated by reference into this Registration
Statement:
(1) The Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2005;
(2) All other reports filed by the Company pursuant to Section 13(a) or 15(d) of the Exchange
Act since December 31, 2005;
(3) The Plan's Annual Report on Form 11-K for the fiscal year ended
December 31, 2005; and
(4) The description of the Company's common stock, $0.01 par value per share (the "Common
Stock"), contained in its Registration Statement on Form 8-A dated April 10, 1987, and any
amendment or report filed for the purpose of updating such description.
All documents
subsequently filed with the Commission by the Company or the Plan pursuant to Sections
13(a), 13(c), 14 and 15(d) of the Exchange Act, prior to the filing of a post-effective amendment
that indicates that all securities offered herein have been sold or that deregisters all securities
then remaining unsold, shall be deemed to be incorporated by reference herein and to be part hereof
from the respective dates of filing such documents. Any statement contained in a document
incorporated or deemed incorporated herein by reference shall be deemed to be modified or
superseded for the purpose of this Registration Statement to the extent that a statement contained
herein or in any subsequently filed document which also is, or is deemed to be, incorporated herein
by reference modifies or supersedes such statement. Any such statement so modified or superseded
shall not be deemed, except as so modified or superseded, to constitute a part of this Registration
Statement.
Item 4. Description of Securities.
Not applicable.
Item 5. Interests of Named Experts and Counsel.
Not applicable.
Item 6. Indemnification of Directors and Officers.
The Company's Certificate of Incorporation (the "Certificate") eliminates personal liability
of directors to the Company or its shareholders for monetary damages for breach of fiduciary duty
as a director, except for: (i) any breach of the duty of loyalty to the Company or its
shareholders; (ii) acts or omissions not in good faith or which involve intentional misconduct or
knowing violations of law;
Table of Contents
(iii) liability under Section 174 of the General Corporation Law of the
State of Delaware ("DGCL") relating to certain unlawful dividends and stock repurchases; or (iv)
any transaction from which the director derived an improper personal benefit. The Certificate also
provides that the Company shall indemnify and advance expenses to each director, officer, employee
and agent to the fullest extent permitted by DGCL.
Section 145 of DGCL provides that under certain circumstances, a corporation may indemnify any
person who was or is a party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding whether civil, criminal, administrative or investigative, by
reason of the fact that he or she is or was a director, officer, employee or agent of the Company
or is or was serving at its request in such capacity in another corporation or business
association, against expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by him or her in connection with such action, suit or
proceeding if he or she acted in good faith and in a manner he or she reasonably believed to be in
or not opposed to the best interests of the Company and, with respect to any criminal action or
proceeding, had no reasonable cause to believe his or her conduct was unlawful.
The Bylaws of the Company provide for indemnification of directors, officers, employees and
agents of the Company to the fullest extent authorized by Section 145 of DGCL against expenses
(including attorneys' fees) and other amounts paid in settlement actually and reasonably incurred
by them in connection with any threatened, pending or completed action, suit or proceeding, whether
civil, criminal, administrative or investigative, in which any such person was or is a party or is
threatened to be made a party. The right to indemnification includes the right to be paid the
expenses incurred in defending or investigating a threatened or pending action, suit or proceeding
in advance of the final disposition of such action, suit or proceeding; provided that, if required
by Delaware law, payment of expenses in advance to an officer or director shall be conditioned upon
receipt by the Company of an undertaking by or on behalf of such director or officer to repay such
amount if it is ultimately determined that he is not entitled to indemnification. The advancement
of expenses, as well as indemnification, pursuant to the Bylaws of the Company is not exclusive of
any other rights which persons seeking indemnification or advancement of expenses from the Company
may have. The Company also maintains an insurance policy pursuant to which its directors and
officers are insured against certain liabilities that might arise out of their relationship with
the Company as directors and officers.
Item 7. Exemption from Registration Claimed.
Not applicable.
Item 8. Exhibits.
See Exhibit Index, which is incorporated herein by reference.
Item 9. Undertakings.
(a) The undersigned Company 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 of 1933;
(ii) To reflect in the prospectus any facts or events arising after the effective date of
this Registration Statement (or the most recent post-effective amendment thereof) which,
individually
Table of Contents
or in the aggregate, represent a fundamental change in the information set forth in
this 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 20% change in the maximum
aggregate offering price set forth in the "Calculation of Registration Fee" table in this effective
Registration Statement;
(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)(l)(i) and (a)(l)(ii) do not apply if the Registration
Statement is on Form S-8, and the information required to be included in a post-effective amendment
by those paragraphs is contained in reports filed with or furnished to the Commission by the
Company pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are
incorporated by reference in this Registration Statement.
(2) That, for the purpose of determining any liability under the Securities Act of 1933, 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.
(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 Company hereby undertakes that, for purposes of determining any liability under the
Securities Act of 1933, each filing of the Company's annual report pursuant to Section 13(a) or
Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of
1934) that is incorporated by reference in 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 of 1933 may be
permitted to directors, officers and controlling persons of the Company pursuant to the foregoing
provisions, or otherwise, the Company 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 Company of expenses incurred or paid by a director, officer or
controlling person of the Company 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 Company 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 Act and will be governed by the
final adjudication of such issue.
