2 LETTER TO STOCKHOLDERS

FELLOW STOCKHOLDERS, We are very pleased to report to you that 1999 was an extremely successful

year for Exodus. In a market that underwent significant change over the past twelve months,

our financial results are a testament to the fact that we were able to meet the continually evolving

expectations of our customers. In the process, we successfully transitioned Exodus from an Internet

Data Center (IDC) company to the industry’s leading provider of complex Web-hosting services.

Revenues for the fiscal year ended December 31, 1999 increased 359 percent to $242.1 million,

compared with $52.7 million in the previous year. The Company reported a net loss for 1999

attributable to common stockholders of $130.3 million, or $0.78 per share, compared with a net

loss attributable to common stockholders of $69.3 million, or $0.55 per share, in the prior year.

Gross margins increased to 19 percent of revenue.

For 1999, EBITDA loss (loss before interest, taxes, depreciation, amortization, and other non-

cash charges) was $44.7 million, compared with $41.9 million the year before. We exited the year

with twelve of our IDCs EBITDA-positive, up from five at the end of 1998.

A YEAR OF GROWTH. In our last report to you, we described several goals that we had set for ourselves

for 1999. These goals were developed to strengthen our position as the leading provider of Internet

systems and network management solutions for companies with mission-critical Internet operations.

We are happy to say that we have not only met these goals but in most cases far exceeded them.

Specifically, we sought to extend our market leadership by establishing Exodus as the pre-

mier brand name in the category of complex Web-hosting services. We believed, as did many

industry analysts, that 1999 would see a shift toward increased business-to-business initiatives

3 in the Internet sector. In fact, this turned out to be the case, as evidenced by the 175 percent

increase we experienced in the number of our hosting customers, to 2,285. By the fourth quarter,

this increase translated into six new Exodus hosting customers each day. The average annual-

ized revenue per IDC customer, which is based on monthly recurring revenue and does not

include any one-time revenue from Professional Services, consulting, or installation fees,

increased dramatically as well, from $133,000 at the close of 1998 to $196,000 as we exited 1999.

As our customer base grew, we began to see a dramatic shift in the balance between enterprise

and Internet-related customers; our client base is now split evenly between these two categories

of companies.

Another of our objectives was to accelerate our domestic and international growth through the

construction of new IDCs and the expansion of our network and worldwide public and private net-

work interconnect arrangements. In 1999, we brought eleven new IDCs online, bringing our total

to nineteen worldwide. This added capacity represents a 300 percent increase in gross square

footage, from 400,000 to 1.6 million. The total number of servers we host worldwide grew in 1999

from 6,600 to over 27,000.

To meet the demands of the expanding Internet, we continued to augment the strength and

capacity of our worldwide network. Our peak Internet exchange rate jumped from 2.7 gigabits

4 per second* to 7.2 gigabits per second*; this higher rate is the equivalent of transmitting an entire

set of encyclopedia over the network every second.

BUILDING EXPERTISE. We also established several new strategic relationships for distribution and tech-

nology in 1999. To help us address new market opportunities presented by the burgeoning

demand for e-business, we acquired Cohesive Technology Solutions.TM This business now forms

the core of an extremely talented and experienced Professional Services organization of nearly

500 people within Exodus.

To further extend our Internet offerings, we acquired Service Metrics,TM which allows us to

provide “Internet Intelligence” through the collection and analysis of Web site performance data.

After the close of the fiscal year, we acquired KeyLabs,TM a leading provider of e-business testing

services, and announced plans to make an equity investment in Mirror Image Internet, Inc.TM This

latter relationship will pave the way for creating the world’s most powerful Content Distribution

platform. Under this relationship, Mirror Image will deploy Content Access Points (CAPsTM)

throughout the entire Exodus IDC network—providing fast, secure, reliable, scalable, and robust

Content Distribution services to content providers, ISPs, and enterprises alike.

In addition to those initiatives, we made two strategic acquisitions in 1999 to meet our goal of

accelerating the expansion of our geographic reach, both in the United States and internationally.

*1/99 to 12/99

5 With the acquisition of American Information Systems,TM we now provide superior co-location, Web-

hosting, Internet Professional Services, and Internet access to corporations in the Midwest. And our

acquisition of Global OnLine JapanTM—one of Japan’s premier Internet service providers—has given

us an immediate presence in the important Asia Pacific market. Also in the international arena, we

expanded our network capacity connecting future Exodus IDCs in Europe, Japan, and North

America, giving us the capacity needed to meet our customers’ growing demands.

LOOKING AHEAD. We are extremely encouraged by our progress to date in the dynamic marketplace of

large-scale, complex Internet operations management—a place in which not just servers, but true

Internet innovation, now reside. In 2000 and beyond, we intend to continue to build the momentum

we have established, with further expansion into new regions, continued development of new

alliances, and enhancements of our Managed and Professional Services and new product offerings.

On behalf of Exodus, we thank you for your continued support.

Sincerely,

Ellen M. Hancock K.B. Chandrasekhar President and Chief Executive Officer Chairman of the Board of Directors

TODAY, OVER 40 PERCENT OF THE TOP INTERNET SITES* HAVE CHOSEN EXODUS.

HERE ARE THE STORIES BEHIND SIX OF THEM. * 2/00 Media Metrix 7 WHAT DO YOU DO WHEN MILLIONS OF CONSUMERS WANT TO BUILD HOME PAGES?

HELP YAHOO! GET PERSONAL.

If the Web is about empowering individuals, it doesn’t get much more individual than this. That’s because Yahoo! helps ordinary folks build their own home pages. At a site that makes it extremely easy to enter the vast new global on-line community now open before them. Exodus helps Yahoo! by providing the network scalability and around-the-clock engineering support demanded by the largest portal in the world. And with many terabytes of Yahoo! information running through multi- ple installations within Exodus Internet Data Centers worldwide, that’s a responsibility we take personally.

8 WHY WOULD ANYONE HOST A HIGH-FLYING PROMOTIONAL PROGRAM?

TO HELP GET BRITISH AIRWAYS’ INTERACTIVE TV SERVICE OFF THE GROUND.

British Airways flights and holidays. In a unique partnership with three cable TV companies, British Airways is enabling almost two million households to plan holidays or view and purchase the products and services offered by the air- line—on TV. Exodus was instrumental in helping British Airways extend their already high- profile travel service with Exodus Managed Services—enabling the close monitoring of this new business venture. From the Exodus IDC in London, British Airways now has connections to the Internet, worldwide.

9 HOW CAN YOU HELP PEOPLE GET VITAL INFORMATION, RAIN OR SHINE?

KEEP WEATHER.COM AHEAD OF THE STORM.

When a snowstorm hits the East or a hurri- cane batters the South, people want to know. Enter weather.com. The site supplies current conditions and forecasts for over 77,000 locations worldwide, weather-related news and up-to-the-second coverage of all major weather events. To help weather.com stay on top of all this, the Exodus Professional Services group provided comprehensive network engineering support and detailed site architecture planning. Add our state-of-the-art facilities, high-speed network, and data backup and security services, and weather.com is totally comfortable.

10 HOW DO YOU PROVIDE SUPERIOR SERVICE TO A COMPANY THAT’S FAMOUS FOR IT?

GET NORDSTROMshoes.com UP ON ITS FEET.

Click on this site and you enter the world’s biggest shoe store, with over 20 million pairs of shoes and counting. Nordstrom.com and Nordstromshoes.com are dedicated to providing unconditional satis- faction for their online customers. And so at Exodus, we helped Nordstrom scale from

1 12 servers to more than 60 in just 3 ⁄2 weeks to make the deadline for their shoe store site launch. By recommending our secure facilities, superior network, and Managed Monitoring Services, our Professional Services group got Nordstromshoes.com up and running in a hurry.

111 HOW CAN YOU HELP COST-CONSCIOUS ONLINE SHOPPERS?

MAKE SURE priceline.com IS OPEN FOR BUSINESS.

Here’s a great idea: link buyers who like to save money with sellers who have excess inventory. Bingo! Welcome to priceline.com, whose motto is, “Name Your Own Price!” Here’s another great idea: to make sure the site is always available, turn to Exodus. Which is exactly what priceline.com did. This virtual marketplace took advantage of our multiple Managed Service offerings, and expanded security offerings includ- ing best-of-breed firewall technology—all from within our secure facilities. With priceline.com and Exodus, everyone comes out ahead.

12 WHAT CAN YOU DO WHEN ABSOLUTELY EVERYONE WANTS TO KNOW?

MAKE SURE USATODAY.COM CAN TELL THE STORY.

Today, with more than 200,000 pages dedi- cated to the latest national and international news, USATODAY.com ranks as the #1 news- paper site on the Internet. But such fast growth is nothing com- pared with the spike in viewership the site gets when an unexpected, major news event occurs. To ensure the highest availability and fastest download times, USATODAY.com relies on Exodus for con- sistent service, secure facilities, and the high-capacity network connections a news organization expects.
