For further information concerning certain matters described herein see the Form 8-K. - -------------------------------------------------------------------------------- 2 The WAMU Transaction Is the Best For GWF Shareholders - -------------------------------------------------------------------------------- o Creates immediate as well as ongoing value for GWF shareholders o Creates a premier consumer banking franchise o Represents the low risk execution alternative for GWF shareholders o Ahmanson Proposal utilizes questionable assumptions and relies on imprudent leverage o Compared to Ahmanson, WAMU has a proven track record of successfully integrating large acquisitions and delivering shareholder value o The pro forma combined GWF/WAMU is financially superior to a combined GWF/Ahmanson - -------------------------------------------------------------------------------- [Washington Mutual Logo] [Great Western Logo] 3 Creates Immediate As Well As Ongoing Value for GWF Shareholders - -------------------------------------------------------------------------------- o Highly accretive to earnings per share -- 56% projected 1999E accretion per GWF share o Earnings growth improved above what GWF shareholders could expect on a stand-alone basis -- 32% 1997E-1999E forecasted EPS growth o Capital ratios remain strong as excessive leverage is not required to produce attractive financial returns -- pro forma tangible common ratio is projected to be in excess of 5% o Significant growth in net interest income driven by high projected loan originations at reasonable margins o WAMU has a consistent record of regular dividend increases -- 29% average annual increase since 1991 - -------------------------------------------------------------------------------- [Washington Mutual Logo] [Great Western Logo] 4 Creates a Premier Consumer Banking Franchise - -------------------------------------------------------------------------------- o Will rank in top three in deposit market share in California, Washington and Oregon and 5th in Florida o Number one-ranked originator of single family mortgage loans on a combined basis in California, Washington and Oregon o WAMU's proven consumer banking capabilities have produced cumulative average growth rates since 1993 of 7% in consumer loans, 52% in depositor fee income, 23% in retail checking accounts and 10% in total households served. These capabilities will be applied to GWF's customer base - -------------------------------------------------------------------------------- [Washington Mutual Logo] [Great Western Logo] 5 Represents the Low Risk Execution Alternative For GWF Shareholders - -------------------------------------------------------------------------------- o The WAMU management team has worked together for a significant number of years and has considerably greater experience integrating large acquisitions as compared to Ahmanson's management team o GWF's systems are compatible with WAMU's, not with Ahmanson's o WAMU will continue to use the GWF name in California, benefiting customer retention o WAMU is a friendly transaction in which integration planning has already begun. Ahmanson is a hostile offer that has antagonized employees o A faster solution to the situation is better for shareholders, employees and customers. WAMU is on track for a closing in late June or early July - -------------------------------------------------------------------------------- [Washington Mutual Logo] [Great Western Logo] 6 AHM Proposal Utilizes Questionable Assumptions and Relies On Imprudent Leverage - -------------------------------------------------------------------------------- o Ahmanson's projected cost savings are $114 million or 34% greater than WAMU's, a difference that cannot be supported by Ahmanson's proposed 100 additional branch closures o Ahmanson's earnings are significantly more sensitive to achieving the stated cost savings target than are WAMU's o Ahmanson made significant changes in its operating assumptions when it increased its bid; absent these changes the transaction is dilutive in 1999 o Ahmanson's EPS forecasts depend on massive share repurchases that leave little room for error -- share repurchases plus dividends are projected to equal 178% of net income through 1999 o Massive share repurchases will result in Ahmanson continuing to have one of the lowest consolidated tangible common equity ratios in the industry -- pro forma ranking of 92 out of 93 thrifts o Ahmanson's intangibles will total 58% of total equity and the amortization expense will be in excess of 25% of net income available to common stock in 1998 - -------------------------------------------------------------------------------- [Washington Mutual Logo] [Great Western Logo] 7 Compared To Ahmanson, WAMU Has a Proven Track Record Of Successfully Integrating Large Acquisitions and Delivering Shareholder Value - -------------------------------------------------------------------------------- o WAMU has consistently produced greater returns to shareholders -- ten year total return: 24% vs. 9% o WAMU has consistently maintained stronger asset quality and reserve coverage ratios -- NPA-to-assets: 0.93% vs. 2.06; Reserves-to-NPLs: 110% vs. 50% o WAMU has delivered superior growth in earnings per share and dividends per share -- annual dividend growth: 29% vs. 0% o WAMU has a more attractive mix of loans and deposits and is geographically more diversified -- consumer loans: 10% vs 3%; transaction + money market + savings accounts: 42% vs. 32% o WAMU's loan originations have been growing while Ahmanson's have been declining -- 1994 to 1996 originations: 46% increase vs. 47% decrease - -------------------------------------------------------------------------------- [Washington Mutual Logo] [Great Western Logo] 8 The Pro Forma Combined GWF/WAMU Is Superior To a Combined GWF/Ahmanson - -------------------------------------------------------------------------------- o GWF shareholders, for each GWF share, will receive greater earnings and book value in a WAMU transaction than in an Ahmanson transaction o A combination with WAMU will produce higher growth rates in EPS and book value than a combination with Ahmanson which should result in higher valuation multiples o Return on assets and equity are materially higher in a combination with WAMU o Capital, asset quality and reserve coverage ratios are significantly stronger in a combination with WAMU - -------------------------------------------------------------------------------- [Washington Mutual Logo] [Great Western Logo] 9 The Pro Forma Combined GWF/WAMU Is Superior To a Combined GWF/Ahmanson - -------------------------------------------------------------------------------- WAMU Ahmanson Transaction Proposal ----------- -------- EPS - --- 1999E Accretion to GWF Shareholder 56% 39% 1997E-1999E Growth 32% 20% Capital - ------- 12/31/97E Tangible Common Equity Ratio 4.91% 3.46% and projected to and projected increase to be flat 12/31/97E Tangible Book Value per GWF $19.28 $12.22 Share Returns - ------- 1999E Return on Assets 1.35% .98% 1999E Return on Common Equity 23.1% 11.7% Asset Quality - ------------- NPAs/Assets @ 3/31/97 0.94% 1.35% Reserves/NPLs @ 3/31/97 119% 83% - -------------------------------------------------------------------------------- [Washington Mutual Logo] [Great Western Logo] 10 GWF Per Share Deal Value -- WAMU & Ahmanson - -------------------------------------------------------------------------------- [Graph with two lines, one solid line for WAMU Transaction and one dotted line for Ahmanson Proposal] [Horizontal line: dates (2/18/97 - 5/19/97);
