Federated Investors, Inc.

Notes to Unaudited Pro Forma Consolidated Financial Statements

Year Ended December 31, 2005,

And Quarter Ended March 31, 2006

(1) Basis of presentation

On July 14, 2006, Federated Investors, Inc. (Federated) completed the acquisition of MDTA LLC (MDTA) (Acquisition). Federated acquired approximately 89 percent of the outstanding equity interests of MDTA with a right to acquire the remaining 11 percent by June 30, 2007. The transaction includes an initial purchase payment of approximately $102 million, an additional purchase price payment of approximately $8 million in the first half of 2007 upon acquisition of the remaining 11 percent outstanding equity interests and a series of contingent payments totaling as much as $130 million over the next three years based on growth. The transaction was accounted for as a purchase under U.S. GAAP.

The following unaudited pro forma consolidated balance sheet as of March 31, 2006 has been prepared to give effect to the acquisition as if such transaction occurred on March 31, 2006. The unaudited statements of income for the three months ended March 31, 2006, and for the year ended December 31, 2005, have been prepared to give effect to the Acquisition as if such transaction occurred at the beginning of the periods presented.

The following is a description of the individual columns included in the unaudited pro forma consolidated financial statements:

Federated: The information presented as of and for the three months ended March 31, 2006, was derived from Federated’s unaudited historical consolidated financial statements. The information for the year ended December 31, 2005, was derived from Federated’s audited consolidated financial statements for 2005.

MDTA LLC: The information presented as of and for the three months ended March 31, 2006, was derived from MDTA’s unaudited historical financial statements. The information for the year ended December 31, 2005, was derived from MDTA’s audited financial statements for 2005. Information presented in this column includes certain reclassifications to conform MDTA’s financial statements with Federated’s presentation.

Pro Forma Adjustments: The pro forma adjustments are based on available information and certain assumptions that we believe are reasonable under the circumstances. Actual adjustments to record the purchase could be different. The adjustments represent adjustments that are either directly attributable to the Acquisition or otherwise required by Article 11 of Regulation S-X to conform accounting treatment across all periods presented. These adjustments are considered to have a continuing impact on the financial position and results of operations of Federated.

5

These unaudited pro forma consolidated financial statements and notes thereto are provided for informational purposes only and do not purport to be indicative of the actual financial position or results of operations had such transaction been completed on the dates indicated or of future results of operations. In addition, the unaudited pro forma consolidated financial statements do not include any synergies that may be realized as a result of combining the entities.

These unaudited pro forma consolidated financial statements should be read in conjunction with Federated’s Annual Report on Form 10-K for the year ended December 31, 2005, Quarterly Report on Form 10-Q for the periods ended March 31, 2006, and June 30, 2006, and Current Report on Form 8-K as amended filed July 20, 2006.

(2) Pro forma adjustments

(a) To record the total cost of the Acquisition, which was equal to approximately $110.4 million and included the following components:

Cash consideration	$	102.0
Debt	$	8.0
Other direct costs of acquisition	$	0.4

(b) To reduce net working capital of MDTA at closing to $0 in accordance with the Acquisition agreement.

(c) To eliminate historical goodwill recorded on MDTA’s balance sheet.

(d) To record the fair value of the assets acquired including goodwill, other identifiable intangible and tangible assets, and liabilities assumed. For purposes of the accompanying pro forma consolidated financial statements, we have recorded the acquired assets and liabilities assumed using preliminary estimates of fair value as of the acquisition date. A valuation is currently in progress to determine the fair value of those assets. We believe that the excess purchase price over the value of the acquired tangible assets and assumed liabilities will be allocated to various assets including but not limited to customer relationships, noncompetition agreements, internally developed software and goodwill. However, there can be no assurance that the actual allocation will not differ significantly from the pro forma allocation.

(e) To eliminate certain revenues and expenses attributable to certain historical operations of MDTA which were not acquired by Federated.

(f) To record a liability for costs to be incurred under certain contractual obligations of MDTA that existed before the closing date but have no economic benefit to the combined company.

6

(g) To record a liability for termination benefits resulting from an involuntary employee termination plan that was approved in connection with the Acquisition and pertains to certain MDTA employees.

(h) To reflect the elimination of MDTA’s note payable to it’s affiliate. This note was not part of the purchase of MDTA.

(i) To adjust compensation expense in accordance with compensation arrangements agreed to in connection with the Acquisition agreement.

(j) To increase amortization expense based on preliminary estimates of fair value and an average estimated useful life of 10 years for the amortizable assets including customer relationships, the noncompetition agreement and internally developed software. Should the actual allocation of the purchase price differ significantly from the pro forma allocation as described in Note (2)(d) above, actual amortization expense could differ significantly from pro forma amortization.

(k) To eliminate interest expense associated with a note payable with an affiliate of MDTA. This note was not part of the purchase of MDTA.

(l) To record interest expense on the purchase price financed by the minority interest holder. Average annual interest rates of 4.42% and 3.17% were used to calculate the interest expense for the three months ended March 31, 2006 and the year ended December 31, 2005, respectively, and were derived in accordance with the terms of the Acquisition agreement.

(m) To give effect to foregone interest income from invested cash of Federated as a result of using cash equal to approximately $102.4 million for the acquisition. Average annual interest rates of 4.42% and 3.17% were used to calculate foregone interest for the three months ended March 31, 2006, and the year ended December 31, 2005, respectively.

(n) To reflect the income tax impacts of the pro forma adjustments described above and to record the tax on MDTA’s historical results at the applicable federal statutory rate. MDTA is organized as a partnership under the U.S. federal tax laws.

(o) To give effect to stock-based compensation as though Statement of Financial Accounting Standards No. 123 (revised 2004), “Share-Based Payment,” had been adopted on January 1, 2005. This adjustment is necessary to conform the accounting treatment for stock-based compensation across all periods presented in accordance with Article 11 of Regulation S-X.
