Unaudited pro forma condensed combined financial information The following unaudited pro forma condensed combined financial data are based on our historical financial statements and the historical financial statements of AMICO. The information included in the "Gibraltar historical" column of the unaudited pro forma condensed combined financial data sets forth our historical balance sheet data as of September 30, 2005 and our historical statement of income data for the year ended December 31, 2004 and the nine months ended September 30, 2004 and 2005, which data are derived from our audited and unaudited consolidated financial statements. The information included in the "AMICO historical" column of the unaudited pro forma condensed combined financial data sets forth AMICO's historical balance sheet data as of September 30, 2005 and AMICO's historical statement of operations data for the year ended December 31, 2004 and the nine months ended September 30, 2004 and 2005, which data are derived from AMICO's audited and unaudited consolidated financial statements. The information included in the "Gibraltar historical" column and the "AMICO historical" column for the twelve months ended September 30, 2005 has been calculated by subtracting the applicable unaudited consolidated statement of income data for the nine months ended September 30, 2004 from the sum of (1) the applicable audited consolidated statement of income data for the year ended December 31, 2004 and (2) the applicable unaudited consolidated statement of income data for the nine months ended September 30, 2005. The information contained in the "Pro forma" column of the unaudited pro forma condensed combined balance sheet as of September 30, 2005 gives effect to the following (collectively, the "transactions") as if they had occurred on September 30, 2005: o the acquisition of AMICO; and o the incurrence of new long-term debt and the use of proceeds thereof. The information included in the "Pro forma" column of the unaudited pro forma condensed combined statements of income for the year ended December 31, 2004 and the nine months ended September 30, 2004 and 2005 gives effect to the events described in the bullet points above as if they had occurred on January 1, 2004. The pro forma statement of income for the twelve months ended September 30, 2005 has been derived by subtracting the unaudited pro forma condensed combined statement of income data for the nine months ended September 30, 2004 from the sum of (1) the unaudited pro forma condensed combined statement of income data for the year ended December 31, 2004 and (2) the unaudited pro forma condensed combined statement of income data for the nine months ended September 30, 2005. The unaudited pro forma adjustments are based on available information and certain assumptions that we believe are reasonable. However, these unaudited pro forma adjustments do not include an allocation of the purchase price of AMICO based on fair market value. Therefore, all the acquired assets and liabilities are reflected at their historical book values with the excess consideration recorded as goodwill. The allocation of the purchase price to our acquired assets and liabilities will be completed as soon as reliable information is available. Preliminary pro forma adjustments have been recorded: o to record inventory of AMICO under the same accounting method as our company; and o to exclude the assets and liabilities not acquired as part of the AMICO acquisition from the unaudited pro forma financial data. The adjustments with respect to the new long-term debt reflect the estimated interest rates plus amortization of estimated financing costs. The final interest rates, financing costs incurred and application of proceeds will be determined on the date the new long-term debt is actually incurred and may differ from those reflected in the unaudited pro forma financial data. Our unaudited pro forma financial data do not purport to present what our actual financial position or results would have been if the events described above had occurred as of the dates indicated and are not necessarily indicative of our future financial position or results. For example, we expect our future results to be affected by the following factors, among others: o In connection with our acquisition of AMICO in October 2005, we must record AMICO's inventory on our consolidated balance sheet at fair market value. Our margins from the AMICO business will be depressed in the fourth quarter of 2005 as we sell the inventory acquired. Additionally, the recording of AMICO's acquired inventory at fair market value may result in additional deferred tax assets or liabilities. o We will be required to record identifiable intangible assets and property, plant and equipment acquired in the AMICO acquisition on our consolidated balance sheet at fair market value. Any resulting write-up of assets will increase our depreciation and amortization expense when we depreciate or amortize the acquired assets and will reduce gross profit, operating income, income from continuing operations and net income, and such reductions may be significant. Based upon our past acquisitions and the nature of the assets acquired in the AMICO acquisition, we expect to recognize, when we complete our fair market value calculations, identifiable intangible assets such as trademarks/patents, unpatented technology and customer relationships. We will not complete our fair market value calculations of these assets until early 2006, and we cannot quantify the amount of the write-up of the acquired assets at this time. Amortization periods to be used for these identifiable intangible assets and property, plant and equipment acquired will be based primarily upon the estimated useful lives of the assets, which at this point are not determinable. Additionally, the identification of intangible assets and the recording of the acquired property, plant and equipment at fair market value may give rise to additional deferred tax assets and liabilities. o In connection with the transaction, we paid a prepayment premium of $6.7 million to retire our private placement notes. We also wrote off the deferred financing fees of $0.7 million related to this debt. These charges are not reflected in the unaudited pro forma condensed combined statements of income because they are not considered on-going and will not have a recurring impact on our results of operations. We also will incur charges in our fourth quarter relating to non-capitalized expenses arising out of the AMICO acquisition.

At acquisition, AMICO changed its inventory policy from LIFO to FIFO, which will result in taxable income relating to the reversal of the LIFO reserve that our company will recognize for tax purposes over a four-year period. (3) Reflects estimated additional goodwill resulting from the AMICO acquisition, as if the AMICO acquisition had occurred on September 30, 2005. The determination of the final purchase price, following any post-closing working capital adjustments, for the AMICO acquisition has not been made. For purposes of the unaudited pro forma condensed combined balance sheet, we have used the preliminary purchase price paid in connection with the AMICO acquisition. We have not completed an allocation of the purchase price to our assets and liabilities; such allocation will be completed within one year and, in addition to identifying intangible assets, may give rise to additional deferred tax assets or liabilities. Therefore, all the acquired assets and liabilities are reflected at their historical book values with the excess consideration recorded as goodwill. The purchase price and goodwill have been calculated as follows: (Dollars in millions) Purchase price(a) $ 240.0 Less: net value of assets acquired(b) 83.6 _________ Goodwill balance 156.4 Less: Historical goodwill of AMICO 7.1 _________ Pro forma adjustment $ 149.3 _________ (a) Excludes the impact of any post-closing working capital adjustments, which have not yet been determined.

We have not completed an allocation of the purchase price to our assets and liabilities; such allocation will be completed within one year. Therefore, all the acquired assets and liabilities are reflected at their historical book values with the excess consideration recorded as goodwill. We will be required to record identifiable intangible assets and property, plant and equipment acquired in the AMICO acquisition on our consolidated balance sheet at fair market value. Any resulting write-up of assets will increase our depreciation and amortization costs when we depreciate or amortize the acquired assets and will reduce gross profit, operating income, income from continuing operations and net income, and such reductions may be significant. (2) Represents the cost of sales impact of the alignment of inventory accounting policies. AMICO changed its inventory policy to FIFO from LIFO in order to align its accounting policies with those of our company. Assuming consistent inventory levels, in a period of rising raw material prices the FIFO method results in a higher ending inventory balance and higher gross profit than the LIFO method. (3) Represents the estimated increase in interest expense for the periods indicated incurred as part of the financing for the transactions, assuming the transactions had occurred as of January 1, 2004.
