BROKERAGE SEGMENT – 71% OF 6/30/08 REVENUES
Gallagher operates its Brokerage operations through a network of more than 200 retail and wholesale sales and service offices located throughout the United States and in 14 countries abroad. In addition, Gallagher does business through a Strategic Alliance Network of independent insurance brokers and consultants in more than 100 countries around the world.
RETAIL INSURANCE BROKERAGE OPERATIONS
77% OF 6/30/08 BROKERAGE SEGMENT REVENUES
Gallagher negotiates and places nearly all lines of property & casualty (P/C) insurance, employer-provided health and welfare insurance and retirement solutions, principally for middle-market commercial, industrial, public entity, religious and not-for-profit entities. Revenues are generated through commissions paid by insurance companies, which are usually based upon a percentage of the premium paid by insureds, and through brokerage and advisory fees paid directly by its clients.
Lines of Coverage
• Aviation • Errors & Omissions • Products Liability
• Commercial Auto • Fire • Professional Liability
• Dental • General Liability • Property
• Directors & Officers Liability • Life • Retirement Solutions
• Disability • Marine • Wind
• Earthquake • Medical • Workers Compensation
Gallagher’s retail brokerage operations are organized in approximately 150 geographical profit centers located throughout North America and operate primarily within certain key Niche/Practice Groups, which account for approximately 65% of its retail brokerage revenues. These specialized teams target areas of business and/or industries in which Gallagher has developed a depth of expertise and a large client base.
Niche/Practice Groups
• Agribusiness • Healthcare • Real Estate
• Aviation & Aerospace • Higher Education • Religious Institutions
• Captives • Hospitality • Restaurant
• Construction • Marine • Shopping Centers
• Energy • Not-for-Profit • Technology & Telecom
• Fine Arts • Personal • Transportation
• Global Risks • Professional Groups
• Habitational • Public Entity
2 | | INVESTMENT PROFILE AUGUST 2008 |

Gallagher’s specialized focus on these Niche/Practice Groups allows for highly-focused marketing efforts and facilitates the development of value-added products and services specific to those industries or business segments. Gallagher believes that the detailed understanding and broad client contacts developed within these Niche/Practice Groups provide Gallagher with a competitive advantage.
Gallagher anticipates that its greatest revenue growth over the next several years for its retail brokerage operations will continue to come from: (1) its Niche/Practice Groups and middle-market accounts, (2) cross-selling other brokerage products to existing customers, (3) developing and managing alternative market mechanisms, such as captives, rent-a-captives, deductible plans and self-insurance, (4) mergers and acquisitions.
WHOLESALE INSURANCE BROKERAGE OPERATIONS
23% OF 6/30/08 BROKERAGE SEGMENT REVENUES
Gallagher’s wholesale brokerage operations assist Gallagher’s retail brokers and other unaffiliated retail brokers and agents in the placement of specialized, unique and hard-to-place insurance programs. Revenues are generated by sharing the commission paid to the retail broker by the insurer.
Gallagher’s wholesale brokerage operations are organized in approximately 60 geographical profit centers located in the U.S. and through its approved Lloyd’s of London brokerage in London. In certain cases Gallagher acts as a brokerage wholesaler and in other cases Gallagher acts as a managing general agent or managing general underwriter, distributing specialized insurance coverages for insurance carriers.
More than 75% of Gallagher’s wholesale brokerage revenues come from retail brokers and agents that are not affiliated with Gallagher. Based on revenues, Gallagher’s U.S. wholesale brokerage operation currently ranks as the fifth-largest wholesaler.
Gallagher anticipates growing its wholesale brokerage operations by increasing its number of broker-clients, by developing new managing general agency and underwriter programs, and through mergers and acquisitions.
Strategic Alliance Network
Gallagher has a strong worldwide Strategic Alliance Network of independent broker partners. These relationships are based on strength, service capabilities and shared business philosophies. The network extends Gallagher’s client-service capabilities to more than 100 countries around the world. In 2006, Gallagher introduced a process to brand this network as the Gallagher Optimus Network. Ultimately, this move will give Gallagher’s preferred strategic partners a greater tie to the organization, which should further enhance client services to global accounts.
INVESTMENT PROFILE AUGUST 2008 3

Brokerage Segment Acquisition Strategy
Gallagher is highly growth-oriented. Its Brokerage Segment growth strategy has two primary components — organic growth through strong new business production and the strategic acquisition of complementary businesses. Gallagher completed over 200 acquisitions from 1985 through June 30, 2008, almost exclusively within the Brokerage Segment. Most were regional or local retail or wholesale brokers possessing a strong middle-market focus or significant expertise in a desirable market niche. Gallagher typically acquires companies that fall within the $2 million to $10 million in annual revenues range.
Gallagher is highly selective. An acquisition must offer significant benefits, such as expanding the company’s talent pool, enhancing its geographic presence and service capabilities, and/or broadening and further diversifying its business mix. In selecting acquisition candidates, Gallagher focuses on:
• a corporate culture that matches its own
• a profitable, growing business that could further enhance its ability to compete by gaining access to Gallagher’s greater resources
• clearly defined financial criteria.
Management anticipates that Gallagher’s historical acquisition pace will continue. Contributing to the company’s success as an acquirer is its attractiveness as a merger partner. Growth-oriented independent brokers and consultants are attracted by Gallagher’s aggressive, sales-oriented culture, team-based approach and depth of resources.
RISK MANAGEMENT SEGMENT – 29% OF 6/30/08 REVENUES
Expertise
• Real-time Claims Reporting • Managed Care Services
• Recoveries (subrogation, salvage, etc.) • Loss Control Services
• Appraisal Services • Safety Programs
• Litigation Management • Settlement Management
• Information Management • Education & Training
Based on revenues, Gallagher’s Risk Management operation currently ranks as the world’s largest third-party P/C claims administrator. Gallagher provides contract claim settlement and administration services for enterprises that choose to self-insure and for insurance companies that choose to outsource their claims-handling services.
4 | | INVESTMENT PROFILE AUGUST 2008 |

Approximately 70% of Risk Management Segment revenues are from workers compensation-related claims, 26% are from general and commercial auto liability-related claims and 4% are from property-related claims. In addition, Gallagher generates revenues from integrated disability management programs, information services, risk control consulting (loss control) services and appraisal services, either individually or in combination with managing claims. Revenues are substantially in the form of fees, generally negotiated in advance on a per-claim or per-service basis, depending upon the type and estimated volume of the services to be performed.
Gallagher manages its third-party claims-management operations through a network of approximately 120 offices located throughout the U.S., the U.K., Australia, New Zealand and Canada. Clients are primarily Fortune 1000 companies, larger middle-market companies, not-for-profit organizations and public entities. More than 80% of Gallagher’s risk management revenues come from clients that do not use Gallagher as their retail or wholesale insurance broker.
The Risk Management Segment expects its most significant growth prospects through the next several years will come from Fortune 1000 companies, larger middle-market companies, captives, program business and the outsourcing of insurance company claims departments.
FINANCIAL SERVICES/CORPORATE SEGMENT
This segment manages Gallagher’s interests in tax-advantaged and clean-energy investments as well as its equity ownership position in an alternative investment fund manager that has ownership interests in private investment management firms. Gallagher has been winding down its financial services activities since 2003. Management expects to continue to divest most of the remaining investments in this segment throughout 2008 and 2009.
In addition, Gallagher’s interest expense and corporate-related administrative expenses are reported in this segment.
INVESTMENT PROFILE AUGUST 2008 5

P/C MARKET OVERVIEW
Fluctuations in premiums charged by P/C insurance carriers have a direct and potentially material impact on the insurance brokerage industry. Commission revenues are generally based on a percentage of the premiums paid by insureds and normally follow premium levels. Insurance premiums are cyclical in nature and may vary widely based on market conditions. Various factors, including competition for marketshare among insurance carriers, increased underwriting capacity and improved economies of scale following consolidations, can result in flat or reduced P/C premium rates (a “soft” market). A soft market tends to put downward pressure on commission revenues. Various countervailing factors, such as heavier-than-anticipated loss experience or capital shortages, can result in increasing P/C premium rates (a “hard” market). A hard market tends to favorably impact commission revenues. Hard and soft markets may be broad-based or more narrowly focused across individual product lines or geographic areas.
Following a period of market hardening between 2001 and 2003, beginning in 2004 and continuing into 2008, the P/C market has been relatively soft in most lines and in most geographic areas, notwithstanding an abnormally high level of hurricane activity and other natural disasters in 2005 and 2006.
Recent market surveys by the Council of Insurance Agents & Brokers and supporting analysis by Lehman Brothers Equity Research indicated that commercial rates continued to fall sharply during the first half of 2008, with an average drop in commercial renewal premiums of 13%. The average premium decline for all commercial accounts, regardless of size, was 12.9% for the second quarter 2008, continuing the double-digit decline of the prior five quarters.
