              INDYMAC BANCORP EXPECTS STRONG THIRD QUARTER AND YEAR



PASADENA, Calif. - October 17, 2003 - IndyMac Bancorp, Inc. (NYSE: NDE)
("IndyMac" or the "Company"), the holding company for IndyMac Bank(R) F.S.B.,
today announced that earnings per share for the third quarter 2003 will exceed
the earnings per share of $0.73 reported for the second quarter 2003. While
still in the final stages of review and certification, the third quarter results
will reflect record mortgage production, up 7% over the second quarter of this
year, effective pipeline hedging/risk management to protect IndyMac's margin on
sale of loans, successful capital deployment to increase average earning assets
and improvement in the net interest margin. In addition, given the strong
quarter, the Company's previous guidance for the full year 2003 for earnings per
share ranging from $2.70 to $2.80 per share is lower than is currently
anticipated and should not be relied upon. The Company will issue more formal
guidance on the full year when it releases its earnings and files its Form 10-Q
on October 31st.
