FOR IMMEDIATE RELEASE

Bay View Capital Corporation Announces 2005 Results

San Mateo, California — Bay View Capital Corporation (the “Company”) today announced that its consolidated net loss for the year ended December 31, 2005 was $34.5 million, or $5.22 per diluted share, compared to a net loss of $3.9 million, or $0.59 per diluted share, for the year ended December 31, 2004.

Results for the year included a charge of $25.3 million to record a full valuation allowance on the Company’s deferred tax assets as of December 31, 2005. As a result of the Company’s consolidated pre-tax loss of $11.9 million for the year ended December 31, 2005 and in accordance with generally accepted accounting principles, or GAAP, the Company concluded that its net deferred tax assets of $46.8 million at December 31, 2005 should be fully reserved. Under GAAP, the Company is required to recognize a valuation allowance on its deferred tax assets if, based upon the weight of available evidence, it is more likely than not that some or all of the asset may not be realized. The realization of the deferred tax asset is dependent on the generation of future taxable income and, given the Company’s significant losses, management

has made a judgment that a full valuation allowance is prudent at this time. In reaching this conclusion, the Company did not take into consideration the future taxable income that may arise from the previously announced pending sale of BVAC to a subsidiary of AmeriCredit Corp. and the pending merger with Great Lakes Bancorp, Inc. The Company’s establishment of the full valuation allowance does not affect its net operating loss carryforwards, which totaled $143.4 million at December 31, 2005 and remain available to offset future taxable income. Upon the consummation of the merger, the carrying value of the deferred tax assets will be reevaluated as part of purchase accounting based on estimates of future taxable income of the combined company.

The Company expects to file its Form 10-K Annual Report for 2005 in the next several days. The 10-K will contain management’s discussion and analysis of the Company’s 2005 results of operations.

In connection with the previously announced merger with Great Lakes, the Company has received Federal Reserve approval of its application to become a bank holding company as well as New York State Banking Board approval of the merger. “We are very pleased to have received these approvals from the bank regulatory authorities and look forward to presenting these transactions to our stockholders,” stated Charles G. Cooper, the Company’s President and Chief Executive Officer. The merger remains subject to approval by the Company’s stockholders and those of Great Lakes. The Company currently anticipates that the joint proxy statement/prospectus will be mailed to stockholders of the Company and Great Lakes in early April.

Bay View Capital Corporation is a financial services company headquartered in San Mateo, California. Its common stock is listed on the NYSE: BVC.
