PART I

ITEM 1. BUSINESS Description of Business Mellon Financial Corporation (Mellon) is a global financial services company headquartered in Pittsburgh, Pennsylvania, with approximately $4.7 trillion in assets under management, custody and administration, including $781 billion under management. For a further discussion of Mellon’s products, see “Nature of operations” in Note 1 of Notes to Financial Statements in our 2005 Financial Annual Report to Shareholders, which paragraphs are incorporated herein by reference. See “Available Information” on page 1 of this Report for access to financial and other information regarding Mellon. We were originally formed as a holding company for Mellon Bank, N.A. (“Mellon Bank”), which has its executive offices in Pittsburgh, Pennsylvania. With its predecessors, Mellon Bank has been in business since 1869. Our banking subsidiaries include Mellon Trust of New England, National Association, headquartered in Boston, Massachusetts; Mellon United National Bank, headquartered in Miami, Florida; and Mellon 1st Business Bank, National Association, headquartered in Los Angeles, California, in addition to Mellon Bank. They engage in trust and custody activities, investment management services, banking services and various securities-related activities. The deposits of the banking subsidiaries are insured by the Federal Deposit Insurance Corporation (“FDIC”) to the extent provided by law. Mellon’s businesses are divided into three overall reportable groups -- Asset Management; Payments and Securities Services and Treasury Services/Other Activity. The Asset Management Group is comprised of the Mellon Asset Management and the Private Wealth Management sectors. The Payments and Securities Services Group is comprised of the Asset Servicing and Payment Solutions & Investor Services (PS&IS) sectors. The third group, and fifth sector, is Treasury Services/Other Activity. Further information regarding Mellon’s business sectors is presented in the Business Sectors section found on pages 20 through 31 of Mellon’s 2005 Financial Annual Report to Shareholders, which pages are incorporated herein by reference.

PART I (continued)

Supervision and Regulation Mellon and its bank subsidiaries are subject to an extensive system of banking laws and regulations that are intended primarily for the protection of the customers and depositors of Mellon’s bank subsidiaries rather than holders of Mellon’s securities. These laws and regulations govern such areas as permissible activities, reserves, loans and investments, and rates of interest that can be charged on loans. Similarly, our subsidiaries engaged in investment advisory and other securities related activities are subject to various U.S. federal and state laws and regulations that are intended to benefit clients of investment advisors and shareholders in mutual funds rather than holders of Mellon’s securities. In addition, Mellon and its subsidiaries are subject to general U.S. federal laws and regulations and to the laws and regulations of the states or countries in which they conduct their businesses. Described below are the material elements of selected laws and regulations applicable to Mellon and its subsidiaries. The descriptions are not intended to be complete and are qualified in their entirety by reference to the full text of the statutes and regulations described. Changes in applicable law or regulation, and in their application by regulatory agencies, cannot be predicted, but they may have a material effect on the business and results of Mellon and its subsidiaries. Regulated Entities of the Corporation Mellon is regulated as a bank holding company and a financial holding company under the Bank Holding Company Act of 1956, as amended by the 1999 financial modernization legislation known as the Gramm-Leach-Bliley Act (the “BHC Act”). As such it is subject to the supervision of the Board of Governors of the Federal Reserve System (the “Federal Reserve Board”). In general, the BHC Act limits the business of bank holding companies that are financial holding companies to banking, managing or controlling banks, performing certain servicing activities for subsidiaries, and as a result of the Gramm-Leach-Bliley Act amendments to the BHC Act, engaging in any activity, or acquiring and retaining the shares of any company engaged in any activity, that is either (1) financial in nature or incidental to such financial activity (as determined by the Federal Reserve Board in consultation with the Office of the Comptroller of the Currency (the “OCC”)) or (2) complementary to a financial activity and does not pose a substantial risk to the safety and soundness of depository institutions or the financial system generally (as solely determined by the Federal Reserve Board). Activities that are financial in nature include securities underwriting and dealing, insurance underwriting and making merchant banking investments in commercial and financial companies. They also include activities that the Federal Reserve Board had determined, by order or regulation in effect prior to the enactment of the BHC Act, to be so closely related to banking or managing or controlling banks as to be a proper incident thereto. In order for a bank holding company to engage in the broader range of activities that are permitted by the BHC Act for bank holding companies that are also financial holding companies, (1) all of its depository institutions must be well-capitalized and well-managed and (2) it must file a declaration with the Federal Reserve Board that it elects to be a “financial holding company.” In addition, to commence any new activity permitted by the BHC Act and to acquire any company engaged in any new activities permitted by the BHC Act, each insured depository institution of the financial holding company must have received at least a “satisfactory” rating in its most recent examination under the Community Reinvestment Act. Mellon’s national bank subsidiaries are subject to primary supervision, regulation and examination by the OCC. Mellon Securities Trust Company, The Dreyfus Trust Company and Mellon Trust of New York are New York trust companies and are supervised by the New York State Department of Banking. Mellon Trust of California is a California trust company and is supervised by the State of California Department of Financial Institutions. Mellon Trust of Washington is a Washington trust company and is supervised by the Division of Banks of the Washington State Department of Financial Institutions.

Mellon’s non-bank subsidiaries engaged in securities related activities are regulated by the SEC. We operate a number of broker-dealers that engage in securities underwriting and other broker-dealer activities. These companies are registered broker-dealers and members of the National Association of Securities Dealers, Inc., a securities industry self-regulatory organization. Certain of our subsidiaries are registered investment advisors under the Investment Advisors Act of 1940 and, as such, are supervised by the SEC. They are also subject to various U.S. federal and state laws and regulations and to the laws of any countries in which they conduct business. These laws and regulations generally grant supervisory agencies broad administrative powers, including the power to limit or restrict the carrying on of business for failure to comply with such laws and regulations. Our subsidiaries advise both public investment companies which are registered with the SEC under the Investment Company Act of 1940, including the Dreyfus/Founders family of mutual funds, and private investment companies which are not so registered. The shares of most investment companies advised by our subsidiaries are qualified for sale in all states in the United States and the District of Columbia, except for investment companies that offer products only to residents of a particular state or of a foreign country and except for certain investment companies which are exempt from such registration or qualification. Certain of Mellon’s United Kingdom incorporated subsidiaries are authorized to conduct investment business in the UK pursuant to the UK Financial Services and Markets Act 2000 (“FSMA 2000”). Their investment management advisory activities and their sale and marketing of retail investment products are regulated by the Financial Services Authority (“FSA”). In addition to broad supervisory powers, the FSA may discipline the businesses it regulates. Disciplinary powers include the power to temporarily or permanently revoke the authorization to carry on regulated business following a breach of FSMA 2000 and/or regulatory rules, the suspension of registered employees and censures and fines for both regulated businesses and their registered employees. Certain UK investment funds, including Mellon Investment Funds, an open-ended investment company with variable capital advised by UK regulated subsidiaries of the Corporation, are registered with the FSA and are offered for retail sale in the UK. Certain of Mellon’s public finance activities are regulated by the Municipal Securities Rulemaking Board. Mellon Bank and certain of the Corporation’s other subsidiaries are registered with the Commodity Futures Trading Commission (the “CFTC”) as commodity pool operators or commodity trading advisors and, as such, are subject to CFTC regulation. The types of activities in which the foreign branches of our banking subsidiaries and our international subsidiaries may engage are subject to various restrictions imposed by the Federal Reserve Board. Those foreign branches and international subsidiaries are also subject to the laws and regulatory authorities of the countries in which they operate. Dividend Restrictions Mellon is a legal entity separate and distinct from its bank and other subsidiaries. Our principal sources of funds to make capital contributions or loans to Mellon Funding Corporation, to pay service on our own debt, to honor our guarantee of debt issued by Mellon Funding Corporation or of trust-preferred securities issued by a trust or to pay dividends on our own equity securities, are dividends and interest from our subsidiaries. Various federal and state statutes and regulations limit the amount of dividends that may be paid to us by our bank subsidiaries without regulatory approval. For a further discussion of restrictions on dividends, see the first three paragraphs of Note 24 of Notes to Financial Statements in Mellon’s 2005 Financial Annual Report to Shareholders, which paragraphs are incorporated herein by reference. If, in the opinion of the applicable federal regulatory agency, a depository institution under its jurisdiction is engaged in or is about to engage in an unsafe or unsound practice (which, depending on the financial condition of the bank, could include the payment of dividends), the regulator may require, after notice and hearing, that the bank cease and desist from

Mellon Financial Corporation    5

PART I (continued)

such practice. The OCC and the FDIC have indicated that the payment of dividends would constitute an unsafe and unsound practice if the payment would deplete a depository institution’s capital base to an inadequate level. Moreover, under the Federal Deposit Insurance Act, as amended (the “FDI Act”), an insured depository institution may not pay any dividend if the institution is undercapitalized or if the payment of the dividend would cause the institution to become undercapitalized. In addition, the federal bank regulatory agencies have issued policy statements which provide that FDIC-insured depository institutions and their holding companies should generally pay dividends only out of their current operating earnings. The ability of Mellon’s bank subsidiaries to pay dividends to Mellon may also be affected by various minimum capital requirements for banking organizations, as described below. In addition, Mellon’s right to participate in the assets or earnings of a subsidiary are subject to the prior claims of creditors of the subsidiary. Transactions with Affiliates There are certain restrictions on the ability of Mellon and certain of its non-bank affiliates to borrow from, and engage in other transactions with, its bank subsidiaries and on the ability of such bank subsidiaries to pay dividends to Mellon. In general, these restrictions require that any extensions of credit must be secured by designated amounts of specified collateral and are limited, as to any one of Mellon or such non-bank affiliates, to 10% of the lending bank’s capital stock and surplus, and, as to Mellon and all such non-bank affiliates in the aggregate, to 20% of such lending bank’s capital stock and surplus. These restrictions, other than the 10% of capital limit on covered transactions with any one affiliate, are also applied to transactions between national banks and their financial subsidiaries. In addition, certain transactions with affiliates must be on terms and conditions, including credit standards, that are substantially the same, or at least as favorable to the institution, as those prevailing at the time for comparable transactions involving other non-affiliated companies or, in the absence of comparable transactions, on terms and conditions, including credit standards, that in good faith would be offered to, or would apply to, non-affiliated companies. Unsafe and Unsound Practices The OCC has authority under the Financial Institutions Supervisory Act to prohibit national banks from engaging in any activity which, in the OCC’s opinion, constitutes an unsafe or unsound practice in conducting their businesses. The Federal Reserve Board has similar authority with respect to us and our non-bank subsidiaries, including Mellon Securities Trust Company, a member of the Federal Reserve System. Deposit Insurance Substantially all of the deposits of our bank subsidiaries are insured up to applicable limits by the Bank Insurance Fund (“BIF”) of the FDIC and are subject to deposit insurance assessments to maintain the BIF. The FDIC utilizes a risk-based assessment system which imposes insurance premiums based upon a matrix that takes into account a bank’s capital level and supervisory rating. Such premiums now range from 0 cents for each $100 of domestically-held deposits for well-capitalized and well-managed banks to 27 cents for each $100 of domestically-held deposits for the weakest institutions. Our bank subsidiaries currently are not required to pay insurance premiums to the FDIC. In addition, the Deposit Insurance Fund Act of 1996 authorizes the Financing Corporation (“FICO”) to impose assessments on BIF assessable deposits in order to service the interest on FICO’s bond obligations. The FICO current annual assessment on these deposits is approximately 1.32 cents for each $100 of domestically-held deposits. The FDIC is authorized to raise insurance premiums in certain circumstances. Under the FDI Act, insurance of deposits may be terminated by the FDIC upon a finding that the institution has engaged in unsafe and unsound practices, is in an unsafe or unsound condition to continue operations or has violated any applicable law, regulation, rule, order or condition imposed by a bank’s federal regulatory agency.

Liability of Commonly Controlled Institutions and Related Matters The FDI Act contains a “cross-guarantee” provision that could result in any insured depository institution owned by the Corporation being assessed for losses incurred by the FDIC in connection with assistance provided to, or the failure of, any other insured depository institution owned by the Corporation. Also, under the BHC Act and Federal Reserve Board policy, we are expected to act as a source of financial and managerial strength to each of our bank subsidiaries and to commit resources to support each such bank in circumstances where such bank might not be in a financial position to support itself. Any capital loans by a bank holding company to any of its bank subsidiaries are subordinate in right of payment to deposits and to certain other indebtedness of such bank subsidiaries. In the event of a bank holding company’s bankruptcy, any commitment by the bank holding company to a federal bank regulatory agency to maintain the capital of a subsidiary bank will be assumed by the bankruptcy trustee and entitled to a priority of payment. In addition, under the National Bank Act, if the capital stock of a national bank is impaired by losses or otherwise, the OCC is authorized to require payment of the deficiency by assessment upon the bank’s shareholders, pro rata, and to the extent necessary, if any such assessment is not paid by any shareholder after three months notice, to sell the stock of such shareholder to make good the deficiency. Regulatory Capital The Federal Reserve Board and the OCC have substantially similar risk-based capital and leverage ratio guidelines for banking organizations. The guidelines are intended to ensure that banking organizations have adequate capital given the risk levels of their assets and off-balance sheet financial instruments. The risk-based capital ratio is determined by classifying assets and certain off-balance sheet financial instruments into weighted categories, with higher levels of capital being required for those categories perceived as representing greater risk. Under the capital guidelines, a banking organization’s total capital is divided into tiers. “Tier I capital” consists of (1) common equity, (2) qualifying noncumulative perpetual preferred stock, (3) a limited amount of qualifying cumulative perpetual preferred stock and (4) minority interests in the equity accounts of consolidated subsidiaries (including trust-preferred securities), less goodwill and certain other intangible assets. Not more than 25% of qualifying Tier I capital may consist of noncumulative perpetual preferred stock, trust preferred securities and other so-called “restricted core capital elements.” Commencing Dec. 31, 2003 we deconsolidated the statutory business trusts which have issued trust-preferred securities. As a result, the junior subordinated debentures held by the trusts are now reported on our consolidated balance sheet. The Federal Reserve Board has confirmed the continued qualification of trust-preferred securities as Tier I capital notwithstanding the change in accounting treatment. “Tier II capital” consists of hybrid capital instruments, perpetual debt, mandatory convertible debt securities, a limited amount of subordinated debt, preferred stock that does not qualify as Tier I capital, a limited amount of the allowance for loan and lease losses and a limited amount of unrealized gains on equity securities. “Tier III capital” consists of qualifying unsecured subordinated debt. The sum of Tier II and Tier III capital may not exceed the amount of Tier I capital. The risk-based capital guidelines include capital charges for equity investments in nonfinancial companies. The guidelines require a series of marginal capital charges on covered equity investments that increase with the level of those investments as a percentage of Tier I capital. With certain exceptions, including investments grandfathered under the guidelines, the guidelines require that Mellon and its bank subsidiaries deduct from Tier I capital the appropriate percentage set out below:

BIS II also would set capital requirements for operational risk and refine the existing capital requirements for market risk exposures.
<15%	8%
³15% but <25%	12%
³25%	25%

The risk-based capital requirements identify concentration of credit risk and certain risks arising from non-traditional activities, and the management of those risks, as important factors to consider in assessing an institution’s overall capital adequacy. In addition, the risk-based capital guidelines incorporate a measure for market risk in foreign exchange and commodity activities and in the trading of debt and equity instruments. The market risk-based capital guidelines require banking organizations with large trading activities to maintain capital for market risk in an amount calculated by using the banking organizations’ own internal value-at-risk models, subject to parameters set by the regulators. Under the Federal Reserve Board’s risk-based capital guidelines for bank holding companies, the required minimum ratio of “Total capital” (the sum of Tier I, Tier II and Tier III capital) to risk-adjusted assets (including certain off-balance sheet items, such as standby letters of credit) is currently 8%. The required minimum ratio of Tier I capital to risk-adjusted assets is 4%. At Dec. 31, 2005, Mellon’s Total capital and Tier I capital to risk-adjusted assets ratios were 16.87% and 10.90%, respectively. The U.S. federal bank regulatory agencies’ risk-based capital guidelines are based upon the 1988 capital accord of the Basel Committee on Banking Supervision (the “BIS”). The BIS is a committee of central banks and bank supervisors/regulators from the major industrialized countries that develops broad policy guidelines that each country’s supervisors can use to determine the supervisory policies they apply. The BIS has been working for a number of years on revisions to the 1988 capital accord and in June 2004 released the final version of its proposed new capital framework, with an update in November 2005 (“BIS II”). BIS II provides two approaches for setting capital standards for credit risk – an internal ratings-based approach tailored to individual institutions’ circumstances (which for The U.S. banking and thrift agencies are developing proposed revisions to their existing capital adequacy regulations and standards based on BIS II. In June 2004 the agencies published a joint release describing proposed BIS II-related revisions based on the A-IRB approach of BIS II that would apply only to internationally active U.S. banking organizations but that other U.S. banking organizations could elect to apply. During 2005, the agencies indicated that the publication of a formal notice of proposed rulemaking setting forth the details of the A-IRB provisions for internationally active U.S. banking organizations would be delayed until 2006. In October 2005, the agencies published proposed BIS II-related revisions to their existing risk-based capital guidelines that would apply to U.S. banking organizations that are not internationally active banking organizations. These are often referred to as the “BIS 1A” proposals. The BIS 1A proposals are based on the standardized approach in BIS II. The comment period for these proposals expired on Jan. 18, 2006. The agencies have indicated that the A-IRB provisions for internationally active U.S. banking organizations and the BIS 1A provisions for others will be implemented on similar time frames. Mellon is not an internationally active banking organization and has not made the determination as to whether, once the amendments to the agencies’ guidelines become effective, it will opt to apply the A-IRB provisions applicable to internationally active U.S. banking organizations instead of the BIS 1A provisions applicable to other banking organizations. Mellon is analyzing the potential impact of all proposed revisions on its risk-based capital.

The Federal Reserve Board also requires bank holding companies to comply with minimum Leverage ratio guidelines. The Leverage ratio is the ratio of a bank holding company’s Tier I capital to its total consolidated quarterly average assets (as defined for regulatory purposes), net of the loan loss reserve, goodwill and certain other intangible assets. The guidelines require a minimum Leverage ratio of 3% for bank holding companies that either have the highest supervisory rating or have implemented the Federal Reserve Board’s risk-adjusted measure for market risk. All other bank holding companies are required to maintain a minimum Leverage ratio of 4%. The Federal Reserve Board has not advised us of any specific minimum Leverage ratio applicable to us. At Dec. 31, 2005, our Leverage ratio was 8.33%. The Federal Reserve Board’s capital guidelines provide that banking organizations experiencing internal growth or making acquisitions are expected to maintain strong capital positions substantially above the minimum supervisory levels, without significant reliance on intangible assets. Also, the guidelines indicate that the Federal Reserve Board will consider a “tangible Tier I leverage ratio” in evaluating proposals for expansion or new activities. The tangible Tier I leverage ratio is the ratio of a banking organization’s Tier I capital (excluding intangibles) to total assets (excluding intangibles). Prompt Corrective Action The FDI Act requires federal banking regulators to take prompt corrective action with respect to depository institutions that do not meet minimum capital requirements. The FDI Act identifies the following capital tiers for financial institutions: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized and critically undercapitalized. Rules adopted by the federal banking agencies provide that an institution is deemed to be: “well capitalized” if the banking institution has a Total risk-based capital ratio of 10.0% or greater, a Tier I risk-based capital ratio of 6.0% or greater, and a Leverage ratio of 5.0% or greater, and the institution is not subject to an order, written agreement, capital directive, or prompt corrective action directive to meet and maintain a specific level for any capital measure; “adequately capitalized” if the institution has a Total risk-based capital ratio of 8.0% or greater, a Tier I risk-based capital ratio of 4.0% or greater, and a Leverage ratio of 4.0% or greater (or a Leverage ratio of 3.0% or greater if the institution is rated composite 1 in its most recent report of examination, subject to appropriate Federal banking agency guidelines), and the institution does not meet the definition of a well capitalized institution; “undercapitalized” if the institution has a Total risk-based capital ratio that is less than 8.0%, a Tier I risk-based capital ratio that is less than 4.0% or a Leverage ratio that is less than 4.0% (or a Leverage ratio that is less than 3.0% if the institution is rated composite 1 in its most recent report of examination, subject to appropriate Federal banking agency guidelines) and the institution does not meet the definition of a significantly undercapitalized or critically undercapitalized institution; “significantly undercapitalized” if the institution has a Total risk-based capital ratio that is less than 6.0%, a Tier I risk-based capital ratio that is less than 3.0%, or a Leverage ratio that is less than 3.0% and the institution does not meet the definition of a critically undercapitalized institution; and “critically undercapitalized” if the institution has a ratio of tangible equity to total assets that is equal to or less than 2.0%. The FDI Act imposes progressively more restrictive constraints on operations, management and capital distributions, depending on the capital category in which an institution is classified. At Dec. 31, 2005, all of our bank subsidiaries were well capitalized based on the ratios and guidelines noted previously. A bank’s capital category, however, is determined solely for the purpose of applying the prompt corrective action rules and may not constitute an accurate representation of the bank’s overall financial condition or prospects. The appropriate federal banking agency may, under certain circumstances, reclassify a well capitalized insured depository institution as adequately capitalized. The appropriate agency is also permitted to require an adequately capitalized or undercapitalized institution to comply with the supervisory provisions as if the institution were in the next lower category (but not treat a significantly

undercapitalized institution as critically undercapitalized) based on supervisory information other than the capital levels of the institution. The FDI Act provides that an institution may be reclassified if the appropriate federal banking agency determines (after notice and opportunity for hearing) that the institution is in an unsafe or unsound condition or deems the institution to be engaging in an unsafe or unsound practice. Anti-Money Laundering Initiatives and the USA Patriot Act A major focus of governmental policy on financial institutions in recent years has been aimed at combating money laundering and terrorist financing. The USA PATRIOT Act of 2001 (the “USA Patriot Act”) substantially broadened the scope of U.S. anti-money laundering laws and regulations by imposing significant new compliance and due diligence obligations, creating new crimes and penalties and expanding the extra-territorial jurisdiction of the United States. The U.S. Treasury Department has issued a number of implementing regulations which apply various requirements of the USA Patriot Act to financial institutions such as Mellon’s bank, broker-dealer and investment adviser subsidiaries and mutual funds and private investment companies advised or sponsored by our subsidiaries. Those regulations impose obligations on financial institutions to maintain appropriate policies, procedures and controls to detect, prevent and report money laundering and terrorist financing and to verify the identity of their customers. Failure of a financial institution to maintain and implement adequate programs to combat money laundering and terrorist financing could have serious legal and reputational consequences for the institution. Depositor Preference Statute Under federal law, depositors and certain claims for administrative expenses and employee compensation against an insured depository institution would be afforded a priority over other general unsecured claims against such an institution, including federal funds and letters of credit, in the “liquidation or other resolution” of such an institution by any receiver. Privacy The privacy provisions of the Gramm-Leach-Bliley Act generally prohibit financial institutions, including Mellon, from disclosing nonpublic personal financial information of consumer customers to third parties for certain purposes (primarily marketing) unless customers have the opportunity to “opt out” of the disclosure. The Fair Credit Reporting Act restricts information sharing among affiliates and was amended in December 2003 to further restrict affiliate sharing of information for marketing purposes. Community Reinvestment Act The Community Reinvestment Act requires banks to help serve the credit needs of their communities, including credit to low and moderate income individuals and geographies. Should Mellon or its bank subsidiaries fail to adequately serve the community, potential penalties are regulatory denials to expand branches, relocate, add subsidiaries and affiliates, expand into new financial activities and merge with or purchase other financial institutions. Legislative Initiatives Various legislative initiatives are from time to time introduced in Congress. We cannot determine the ultimate effect that any such potential legislation, if enacted, would have upon our financial condition or operations.

Competition Mellon and its subsidiaries continue to be subject to intense competition in all aspects and areas of our businesses. Our Asset Management Group experiences competition from asset management firms; mutual funds; investment banking companies; bank and financial holding companies; banks, including trust banks; brokerage firms and insurance companies. Our Payments and Securities Services Group competes with domestic and foreign banks offering institutional trust and custody products and cash management products and a wide range of technologically capable service providers, such as data processing and shareholder services firms. Many of our competitors, with the particular exception of bank and financial holding companies and banks, are not subject to regulation as extensive as that described under the “Supervision and Regulation” section and, as a result, may have a competitive advantage over Mellon in certain respects. As part of our business strategy, we seek to distinguish ourselves from competitors by the level of service we deliver to clients. We also believe that technological innovation is an important competitive factor and for this reason have made and continue to make substantial investments in this area. The ability to recover quickly from unexpected events is a competitive factor, and we have devoted significant resources to this. Employees At Dec. 31, 2005, Mellon and its subsidiaries had approximately 16,700 employees. Statistical Disclosure by Bank Holding Companies The Securities Act of 1933 Industry Guide 3 and the Securities Exchange Act of 1934 Industry Guide 3 (together “Guide 3”), require that the following statistical disclosures be made in Annual Reports on Form 10-K filed by bank holding companies.

ITEM 2. PROPERTIES Mellon believes that its owned and leased facilities are suitable and adequate for its business needs. At a number of the locations described below, we are not currently occupying all of the space under our control. Where commercially reasonable and to the extent it is not needed for future expansion, we seek to lease or sublease this excess space. The following is a description of our principal properties: Pittsburgh properties In 1983, Mellon entered into a long-term lease of One Mellon Center, a 54-story office building in Pittsburgh, Pennsylvania. In 2004, we executed a new lease that expires in November 2028. At Dec. 31, 2005, we subleased approximately 17% of this building’s approximately 1,525,000 square feet of rentable space to third parties. In 1984, Mellon entered into a sale/leaseback arrangement pursuant to which we lease the eleven-story office building in Pittsburgh, Pennsylvania known as the Union Trust Building, or Two Mellon Center, while retaining title to the land thereunder. The term of this lease is scheduled to expire in May 2006. Mellon has decided not to renew this lease. At Dec. 31, 2005, we subleased approximately 14% of this building’s approximately 595,000 square feet of rentable space to third parties. Mellon owns the 41-story office building in Pittsburgh, Pennsylvania known as Three Mellon Center or 525 William Penn Place.

Mellon owns the 14-story office building in Pittsburgh, Pennsylvania known as the Mellon Client Service Center. At Dec. 31, 2005, we did not lease any of this building’s approximately 667,000 square feet of rentable space to third parties. The Pittsburgh properties are utilized by all of our business sectors. Philadelphia properties Mellon leases a seven-story office building in Philadelphia, Pennsylvania known as Mellon Independence Center. The term of this lease is scheduled to expire in December 2015. At Dec. 31, 2005, we subleased approximately 63% of this building’s approximately 807,000 square feet of rentable space to third parties. Mellon leases approximately 231,000 square feet of rentable space in a 53-story office building known as Mellon Center in Philadelphia, Pennsylvania. The current term of this lease is scheduled to expire in September 2015. At Dec. 31, 2005, we subleased approximately 25% of this space to third parties. The Philadelphia properties are utilized by all of our business sectors other than the Mellon Asset Management sector. Boston properties Mellon leases approximately 362,000 square feet of rentable space in a 41-story office building known as Mellon Financial Center in Boston, Massachusetts. The current term of this lease is scheduled to expire in December 2013. At Dec. 31, 2005, we subleased approximately 3% of this space to third parties.

PART I (continued)

expire in March 2014. At Dec. 31, 2005, we did not sublease any of this space to third parties. The New York properties are utilized by all of our business sectors. New Jersey property Mellon leases approximately 260,000 square feet of rentable space in a 32-story office building located at Newport Office Center VII, 480 Washington Boulevard, Jersey City, New Jersey. The current term of this lease is scheduled to expire in November 2018. At Dec. 31, 2005, we did not sublease any of this space to third parties. This property is utilized by our Payment Solutions & Investor Services business sector. London headquarters property Mellon leases approximately 234,000 square feet of rentable space in a 6-story office building known as Mellon Financial Centre in London, England. The term of this lease is scheduled to expire in September 2023. At Dec. 31, 2005, we subleased approximately 8% of this space to a third party. This property is utilized by all of the business sectors other than Private Wealth Management. Other properties Mellon also owns and leases additional space for its operations at locations both within and outside the United States. See “Description of Business” on page 3 for information as to where certain of our operations are conducted. For additional information on Mellon’s premises and equipment, see Note 9 of Notes to Financial Statements in Mellon’s 2005 Financial Annual Report to Shareholders, which note is incorporated herein by reference. ITEM 3. LEGAL PROCEEDINGS Various legal actions and proceedings are pending or are threatened against Mellon and our subsidiaries and certain former subsidiaries, some of which seek relief or damages in amounts that are substantial. These actions and proceedings arise in the ordinary course of our businesses and operations and include suits relating to our servicing, investment, mutual fund, advisory, trust, custody, shareholder services, cash management, lending, collections and other activities and operations. Certain actions and proceedings relate to businesses that have been divested. From time to time, Mellon may be involved in regulatory enforcement matters in which claims for disgorgement, the imposition of penalties and/or other remedial sanctions are possible. As previously reported in Mellon’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2005, on March 22, 2005, the United States Attorney for the Western District of Pennsylvania announced that six former employees of a subsidiary of Mellon had been indicted by a federal grand jury in Pittsburgh, Pennsylvania on a series of charges relating to the destruction in April 2001 of approximately 80,000 United States tax returns and payments. In related public comments, the United States Attorney indicated that the investigation is continuing. Mellon is cooperating fully in this investigation. On Jan. 20, 2006, one of these six indicted former employees entered a guilty plea in this matter. As previously reported in a Current Report on Form 8-K dated Sept. 30, 2005, Mellon Investor Services LLC (“MIS”), the transfer agent subsidiary of Mellon Financial Corporation, has received a “Wells Notice” from the Philadelphia District Office of the Securities and Exchange Commission indicating that the staff intends to recommend that the Commission bring a civil injunctive action against MIS for violations of Section 10(b) of the Securities Exchange Act of 1934 and Rule 10b-5 thereunder. A Wells Notice indicates that the SEC’s staff has made a preliminary decision to recommend that the Commission authorize the staff to bring a civil action. However, a Wells Notice is not a formal allegation or proof of wrongdoing. The notice provides MIS the opportunity to respond formally to the SEC staff before the staff makes a final determination whether to recommend that the SEC initiate an action. The staff has informed MIS that its recommendation relates to MIS’ disclosure practices to its transfer agency (issuer) clients during the period 2001 through late 2004 concerning the receipt of fees from a search firm that performs in-depth searches

18    Mellon Financial Corporation

for “lost” shareholders. Fees received by MIS from this firm during this period aggregate to approximately $5 million. MIS believes that the SEC staff has been investigating related practices at other transfer agents. MIS has been cooperating fully with the SEC staff in its investigation and has made a submission explaining why it believes that its conduct was lawful. Because of the complex nature of some of these legal actions and proceedings, it may be a number of years before such matters ultimately are resolved. After consultation with legal counsel, Mellon’s management believes that the aggregate liability, if any, resulting from such pending and threatened legal actions and proceedings will not have a material adverse effect on our financial condition, results of operations and cash flows, although there could be a material effect on results of operations for a particular period. ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS No matters were submitted to security holders for vote during the fourth quarter of 2005. EXECUTIVE OFFICERS OF THE REGISTRANT Information with respect to executive officers of Mellon is set forth on pages 23 and 24 of this Report and is incorporated in Part I by reference.

ITEM 5. MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES The information required by this Item is set forth in Mellon’s 2005 Financial Annual Report to Shareholders in Capital on pages 32 and 33, Liquidity and Dividends on pages 43 and 44, in Fourth Quarter 2005 Review on page 52, in Selected Quarterly Data on pages 53 and 54, in Note 24 of Notes to Financial Statements on page 99 and in Corporate Information on the inside back cover of the Report, which portions are incorporated herein by reference. In October 1996, the Board of Directors declared a dividend, paid Oct. 31, 1996, of one right (a “Right”) issued pursuant to the Shareholder Protection Rights Agreement, dated as of Oct. 15, 1996 (the “Rights Agreement”), for each outstanding share of Mellon’s Common Stock (the “Common Stock”). On Oct. 19, 1999, Mellon amended and restated the Rights Agreement. The Rights are not currently exercisable and trade only with the Common Stock (and are currently evidenced only in connection with the Common Stock). The Rights would separate from the Common Stock and become exercisable only when a person or group acquires 15% or more of the Common Stock or ten days after a person or group commences a tender offer that would result in ownership of 15% or more of the Common Stock. At that time, each Right would entitle the holder to purchase for $135 (the “exercise price”) one one-hundredth of a share of participating preferred stock, which is designed to have economic and voting rights generally equivalent to one share of common stock. Should a person or group actually acquire 15% or more of the Common Stock, each Right held by the acquiring person or group (or their transferees) would become void and each Right held by our other shareholders would entitle those holders to purchase for the exercise price a number of shares of the Common Stock having a market value of twice the exercise price. Should Mellon, at any time after a person or group has become a 15% beneficial owner and acquired control of Mellon’s Board of Directors, be involved in a merger or similar transaction with any person or group or sell assets to any person or group, each outstanding Right would then entitle its holder to purchase for the exercise price a number of shares of such other company having a market value of twice the exercise price. In addition, if any person or group acquires 15% or more of the Common Stock, Mellon may, at its option and to the fullest extent permitted by law, exchange one share of Common Stock for each outstanding Right. The Rights are not exercisable until the above events occur and will expire on Oct. 31, 2006, unless earlier exchanged or redeemed by Mellon. We may redeem the Rights for one cent per Right under certain circumstances. The foregoing description is not intended to be complete and is qualified in its entirety by reference to the Amended and Restated Shareholder Protection Rights Agreement, which is an exhibit to this Report.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE NONE. ITEM 9A. CONTROLS AND PROCEDURES The Corporation’s management, with the participation of its principal executive officer and principal financial officer, has evaluated the effectiveness, as of Dec. 31, 2005, of the Corporation’s “disclosure controls and procedures,” as such term is defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Based upon their evaluation, the principal executive officer and principal financial officer concluded that the Corporation’s disclosure controls and procedures, as of Dec. 31, 2005, were effective to provide reasonable assurance that information required to be disclosed by the Corporation in the reports filed or submitted by it under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms, and to provide reasonable assurance that information required to be disclosed by the Corporation in such reports is accumulated and communicated to the Corporation’s management, including its principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure. See pages 63 and 64 of the Corporation’s 2005 Financial Annual Report to Shareholders for the Report of Management on Internal Control Over Financial Reporting and the related Report of Independent Registered Public Accounting Firm, each of which is incorporated herein by reference. In the ordinary course of business, the Corporation may routinely modify, upgrade and enhance its internal controls and procedures for financial reporting. However, there was no change in the Corporation’s “internal control over financial reporting” (as such term is defined in Rule 13a-15(f) under the Exchange Act) that occurred during the quarter ended Dec. 31, 2005, that has materially affected, or is reasonably likely to materially affect, the Corporation’s internal control over financial reporting.
