                               PROSPECTUS SUMMARY

   This summary sets forth the material highlights of the information contained
elsewhere in this prospectus. It may not contain all of the information that
you should consider before investing in GreenMountain.com, and you should read
the entire prospectus carefully.

   Unless otherwise indicated, all information in this prospectus reflects our
conversion from a limited liability company to a corporation, which will occur
prior to the closing of this offering, and the related exchange of each common
unit of the limited liability company for three shares of common stock of the
corporation. See "Related Party Transactions--Reorganization Transaction."

                               GreenMountain.com

   GreenMountain.com uses the Internet and other media to offer environmentally
friendly electricity and other green products to consumers. Our Web site--
www.greenmountain.com--will use the rich interactive resources of the Internet
to educate consumers about the environmental impact of their everyday purchases
and make it easy and appealing for them to use those purchases as agents of
change for a cleaner and healthier environment. We refer to the concept of
using consumer purchase decisions to effect positive environmental change as
"g*commerce." Our mission is to make Green Mountain the leading brand for
environmentally friendly products.

   "Environmentally friendly" or "green" products, as we use these terms for
purposes of our business plan, are those products that have a less harmful
effect on the environment than other products available to consumers having the
same or a similar use. Based on number of customers served, we currently are
the leading retailer of green electricity to residential customers in
Pennsylvania and California--the two states that have effectively opened their
residential electricity markets to competition. Our green electricity products
are produced from renewable and other environmentally preferable generation
sources, such as wind, water, geothermal, biomass, landfill gas and natural
gas. In addition, we offer solar generation equipment and have very recently
begun to offer other green consumer products over the Internet.

   Three broad trends support our business plan.

  .  Environmental Awareness. We believe that there is growing concern about
     the environment among consumers today and that there is an excellent
     opportunity to build a strong environmental brand presence. We believe
     that, if offered a convenient, cost-effective choice, a large market of
     consumers will purchase a product that is environmentally friendly over
     one that is not.

  .  Deregulation of Electric Utility Markets. We expect deregulation of the
     $200 billion electric utility industry--the largest industrial source of
     air pollution in the United States--to provide consumers in more than
     half the states with a choice of electricity supplier and generation
     source by the end of 2003.

  .  Growth of the Internet. The Internet is emerging as one of the most
     significant global communications media, enabling millions of people to
     share information and conduct business electronically. We believe that
     online retailers are able to communicate more efficiently and
     effectively with more customers than traditional retailers.


   Our predecessor, GreenMountain Energy Resources L.L.C., was formed in
February 1997 and commenced operations in August 1997. As a result, we have
only a limited operating history upon which you can evaluate our business and
prospects. For the year ended December 31, 1998, we generated revenues of $1.5
million and

                                       4

                                                                  Choose wisely.
<PAGE>

incurred net losses of $46.0 million, and for the first quarter of 1999, we
generated revenues of $4.1 million and incurred net losses of $19.8 million.
More than 99% of our revenues have come from green electricity sales in
Pennsylvania and California. We expect to incur net losses in subsequent fiscal
periods. Because we expect to continue to incur significant market development
expenses, we will need to generate significant revenues to achieve
profitability in the future.

   Our Web address is www.greenmountain.com. Our principal executive offices
are at 55 Green Mountain Drive, South Burlington, Vermont 05403. Our telephone
number is 802.846.6100. The information on our Web site is not part of this
prospectus.

                             Our Business Strategy

   We are the first and only company to offer green electricity to residential
customers in both Pennsylvania and California. Although to date we have
primarily utilized traditional media in our marketing efforts, we are also one
of the first companies to offer green electricity products over the Internet.
We intend to take advantage of this first mover momentum to offer a wide
variety of green consumer products over the Internet.

   To fulfill our mission, we have developed a strategy consisting of the
following key elements:

  .Position Green Mountain as the most trusted and best known environmental
   brand;

  .Offer convenience and selection to purchasers of green consumer products;

  .Develop and maintain our Web site as a state-of-the-art, interactive
   commerce platform that makes purchasing our green products easy and
   appealing; and

  .Develop and maintain an online community that fosters and supports
   g*commerce.

                         The GreenMountain.com Web Site

   Our Web site is being upgraded to provide consumers with easy access to a
broad selection of green consumer products and in-depth, educational
environmental content. Our focus in this effort is on providing content with
environmental appeal to people of all ages, such as news articles, product
research information, corporate environmental value added reports and
environment-related tools, games and quizzes. Our approach is to compile
content from multiple sources and integrate it with our own editorial content
to increase its usefulness and the convenience, relevance and enjoyment of
consumers' visits to our Web site, thereby promoting increased traffic and
sales of our green products. We expect that our current upgrade will be
complete by October 1, 1999.

                              Our Management Team

   Our management team is led by Sam Wyly, our Chairman. Mr. Wyly, a computer
software entrepreneur, has created and managed several public and private
companies. In 1981, he co-founded Sterling Software, a New York Stock Exchange-
listed supplier of software products and services, and he currently serves as
its Chairman. He also serves as Chairman of the Executive Committee of Sterling
Commerce, a leading provider of business-to-business electronic commerce
software and network services that was spun off by Sterling Software in 1996.
Since August 1997, entities affiliated with the Wyly family have invested more
than $70 million in our company. After this offering, Sam Wyly, Evan Wyly and
Lisa Wyly will collectively own of record or otherwise have voting control over
2,431,866 shares, or 4.8% of the shares outstanding. Because of this interest,
as well as the management positions of these individuals, we expect that the
Wyly family will continue to exercise significant control over our direction
and management following the closing of this offering.

<PAGE>


   Our managers have substantial expertise in brand development and marketing,
as well as Internet-related technologies. In addition, we have established
strategic relationships with leading marketing and technology companies to help
us accomplish our mission.

                          Our Environmental Commitment

   Our ability to obtain customers and generate sales depends on maintaining
our reputation as a company making a positive contribution to the environment.
We stake our reputation on the environmental soundness of our green products,
and we view our environmental integrity as one of our most important assets.

   We believe strongly in our g*commerce vision. We intend to use the broad
reach of the Internet to aggregate the g*commerce impact of the large online
community, and we believe that the power of this community to effect
environmental change will be significant.

   We intend to closely monitor our effect on the environment and consider it
an essential measure of our success. We have established an Environmental
Advisory Board, the management position of Chief Environmental Officer and a
committee of our board of directors, which will be responsible for reviewing
our adherence to our environmental principles.

                                  RISK FACTORS

   This offering involves a high degree of risk. You should carefully consider
the following risk factors, in addition to the other information in this
prospectus, before purchasing shares of GreenMountain.com common stock. Each of
these risk factors could adversely affect our business, operating results and
financial condition and the price of our common stock.

   RISKS RELATED TO ESTABLISHMENT OF OUR BUSINESS

   Our Business Plan Is Novel And Our Business May Not Prove To Be Profitable.
 Our business plan is novel and without established precedent. It relies on
three broad trends:

  .The willingness of consumers to use their purchasing decisions to address
   environmental concerns;

  .The movement from government controls to free market competition in the
   electric utility industry; and

  .Increasing use of the Internet for commerce transactions.

Our ability to grow our customer base and to generate sales sufficient for us
to achieve profitability depends on the continuation of these trends and the
successful implementation of the primary components of our business strategy.

   To date, more than 99% of our revenues have come from sales of our green
electricity products in Pennsylvania and California. To grow our customer base
and generate increased sales, we must:

  .Increase awareness of the Green Mountain brand;

  .Offer a broad selection of green consumer products;

  .Upgrade our Web site to accommodate and support expanded product
   offerings; and

  .Create an online community of people with shared concerns about the
   environment.

   The novel interaction of these factors presents a high degree of uncertainty
as to whether we can achieve profitability. Many of these factors are outside
our control. We cannot assure you that our business or your investment in our
stock will be profitable.

   Both Investors And Our Management Will Have Very Limited Information
Available To Them In Making Decisions Relating To GreenMountain.com Because Of
Our Very Short Operating History And Because Of The New And Rapidly Evolving
Markets In Which We Operate.  We commenced active operations in August 1997 as
a retail marketer of green electricity products and determined in late 1998 to
expand our retail marketing efforts by developing a state-of-the-art,
interactive commerce platform to offer other green consumer products. We have a
very limited operating history upon which an investor may evaluate our company,
our current business and our prospects can be based. Our business model is
evolving and an investor in our common stock must consider the substantial and
sometimes unforeseeable expenses frequently encountered by early stage
companies, companies that are in the midst of significant business changes and
companies that are in new and rapidly evolving markets, such as the retail
marketing of electricity and online commerce. Similarly, our management has
only a limited operating history on which to base important business decisions.
This lack of information will make these management decisions very difficult
and the outcome of the decisions uncertain. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations" and "Business--Our
Strategy."

   We Have Incurred Losses, We Anticipate Losses Will Continue And We May Never
Achieve Profitability. We have recorded a substantial net loss for each fiscal
period since our inception and expect to continue to incur substantial net
losses for the foreseeable future. We incurred net losses of approximately
$46.0 million in 1998 and approximately $19.8 million in the first quarter of
1999. In connection with the implementation of our expanded business strategy
and the growth of our business, we expect our cost of sales and operating
expenses to increase significantly, especially in the areas of sales, marketing
and brand promotion. We will, therefore, need to generate significant revenues
to achieve profitability. We may never achieve profitability. Even if we do, we
may be unable to sustain or increase profitability in the future. See "Selected
Financial Information" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations."

   Our Ability To Grow Our Customer Base And Generate Sales Depends On
Positioning The Green Mountain Brand And Maintaining Our Reputation And The
Credibility Of Our Products. In order to grow our customer base and generate
sales, we believe we must position the Green Mountain name as the leading
environmental brand and maintain our reputation as a company making a positive
contribution to the environment, particularly in the Internet market and in
deregulated electricity markets within the United States. Promoting and
positioning the brand will depend largely on the success of our marketing
efforts and our ability to provide high quality products and customer service.
We cannot assure you that we will be successful in this regard. Building the
Green Mountain brand will require substantial marketing expenditures. Our sales
and marketing expenses were $33.0 million for 1998 and $12.4 million in the
first quarter of 1999. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations." We cannot assure you that our brand
promotion activities will result in increased revenues or that any such
revenues will offset our marketing expenditures.

   State and federal regulators and environmental and consumer groups
scrutinize claims regarding the environmental benefits of products and from
time to time challenge the environmental benefits of products that claim to be
green, including those offered by us. In addition, state or federal regulators
may establish criteria which we would be required to meet in order to
characterize our products as "environmentally friendly" or "green," or they may
require detailed disclosure of the basis of our characterization of our
products. Compliance with rules of this type could be burdensome, particularly
in the highly technical area of electricity marketing. Maintaining our
reputation and the credibility of our products, as well as our environmental
message, will depend on our ability to respond to these claims and comply with
these rules effectively and efficiently. Although we believe that our claims
regarding the environmental benefits of our products are accurate and
supportable and that we will be able to comply with any applicable regulations,
we cannot assure you that these challenges or compliance with regulations of
this type will not adversely affect our reputation, our customer base or our
revenues. See "Business--Our Strategy."

   Our Ability To Grow Our Customer Base And Generate Sales Depends On
Broadening Our Product Offerings. Until very recently, our consumer product
offerings consisted solely of green electricity products and solar generation
equipment, each of which we currently offer only in Pennsylvania and
California. To date, more than 99% of our revenues have come from green
electricity sales in those two states. We have recently begun offering a
limited number of other products that are also available to consumers outside
Pennsylvania and California. See "Business--Other Products--Recently Announced
Product Offerings." In order to grow our customer base and generate sales, we
must broaden our product offerings to include other green consumer products
that can be offered outside of deregulated utility markets. We cannot assure
you that we will be able to do so. We do not intend to manufacture any products
but rather will sell products produced for us by others under the Green
Mountain brand and, accordingly, we will need to establish relationships with
third parties to purchase or otherwise obtain such products. We will also need
to enter into relationships with third parties to make their own green products
available through our Web site. Our experience in purchasing and marketing
green electricity may not be effective in purchasing and marketing other green
consumer products. We cannot assure you that we will be able to establish the
third-party relationships necessary to broaden our product offerings as we
plan. Moreover, the commercial availability of some of the products that we
hope to offer--for example, fuel cells for homes, offices and cars--is
dependent on technological advances. We cannot assure you when or even that
such advances will occur, that we will be able to develop profitably a
sufficient selection of green consumer products or that any of our products
will achieve market acceptance. See "Business--Our Strategy."

                                       10

                                                                  Choose wisely.
<PAGE>


   To Attract Customers And Make Sales Over The Internet, We Must Develop Our
Web Site And Implement Ongoing Improvements To Our Web Site In The Face Of
Rapid Technological Change. Our ability to attract consumers and sell them our
products over the Internet will depend on our ability to design, develop and
maintain a state-of-the-art Web site. The development of Web sites requires
substantial expenditures and lead time. As of March 31, 1999, we have spent
$1.1 million on the current upgrade of our Web site, and we expect to spend
another $4.5 million by October 1, 1999, when we expect this upgrade to be
complete. We are depending on Strategic Interactive Group, a specialized Web
site developer, for the upgrade of our Web site. If Strategic Interactive Group
does not meet our expectations, we would have to retain another Web site
developer and the upgrade of our Web site could be delayed. We cannot assure
you that the current upgrade of our Web site will be complete by October 1,
1999 or that our Web site will be successful in attracting customers after this
upgrade is complete. When we launch our upgraded Web site, it could contain
errors that are discovered after it is launched and, as a result, we may be
required to modify the Web site to correct these errors. We cannot assure you
that we will be able to modify our Web site to correct any errors or that we
will be able to implement the ongoing improvements that we believe are required
for the continued success of a Web site, and we cannot estimate the related
costs with any certainty. To date, approximately 4% of our customer sign-ups
for our green electricity products have come through our Web site. We have only
very recently begun offering other green consumer products over the Internet.

   The online commerce industry is characterized by:

  .Rapid technological changes;

  .Frequent emergence of new industry standards and practices; and

  .Continual changes in user and customer requirements and preferences.

Failure to adapt to the evolving technologies, industry standards and user
requirements and preferences on an ongoing basis could have a material adverse
effect on our ability to attract customers to and make sales through our Web
site. We cannot assure you that we will be successful in this regard. See
"Business--Our Strategy" and "Business--Our Web Site."

   Our Failure To Develop And Maintain Strategic Web Site Relationships Could
Adversely Affect Our Ability To Attract Customers To Our Web Site. We believe
that in order to attract significant traffic to our Web site and thereby grow
our customer base we will need to establish and maintain relationships with
Internet portals, which are Web sites that offer a broad array of resources and
services on the Internet such as e-mail, discussion forums, search engines and
on-line shopping malls, to attract traffic to their site, and other high-
traffic Web sites that will carry links to our new Web site. For example, we
have entered into an arrangement with Yahoo! under which Yahoo! will place
banner advertising and button links on its properties and deliver e-mail, all
containing information about our energy business. We will also need to
establish and maintain relationships with content providers that will provide
our Web site with content that appeals to consumers who are concerned about the
environment. Competition exists for these types of relationships and we likely
will have to pay significant fees to establish and maintain these
relationships. We cannot assure you that we will be able to enter into or
maintain appropriate relationships or that, even if we do, we will attract
significant traffic to our Web site, grow our customer base or generate sales.

   Our Ability To Expand Our Existing Green Electricity Business Into New
Markets Depends On The Outcome Of The Deregulation Process In Each State. We
believe that utility deregulation in the United States will continue on a
state-by-state basis. To date, however, only four states--Pennsylvania,
California, Massachusetts and Rhode Island--have implemented competition on a
statewide basis. Moreover, deregulation is a political process and its
continuation, as well as the timing and form of deregulation in any particular
state, cannot be predicted with any certainty. Specific features of
deregulation programs vary significantly from state to state. Our ability to
enter and compete in any particular deregulated market will depend on the
specific features, including the consumer protection provisions, of that
market's deregulation program. For example, the Pennsylvania program has
afforded us greater opportunity than the California program. We cannot assure
you that deregulation will continue or that the deregulation program
implemented in any particular state in the future will allow effective
competition. If it does, we may face additional competition and we cannot
assure you that we will be able to compete successfully in any state. If
deregulation does not continue as we currently anticipate, we would be unable
to expand our existing green electricity business as contemplated by our

                                       11

<PAGE>

business plan and our financial prospects would be materially and adversely
affected. In any event, we may incur significant expenses in connection with
our lobbying efforts. See "Business--The Opportunity--Deregulation is
Empowering Consumers to Change the Way Electricity is Made."

   OTHER RISKS RELATED TO OUR BUSINESS GENERALLY

   Our Operating Results May Fluctuate Significantly And Cause Volatility In
Our Stock Price. Our operating results may fluctuate significantly from quarter
to quarter and year to year. Our limited operating history, in combination with
the recent expansion of our business strategy, also makes the prediction of
future results of operations impossible. We believe that period-to-period
comparisons of our operating results are not meaningful and that the results
for any particular period should not be relied on as an indication of future
performance.

   Our revenues and operating results may vary significantly from quarter to
quarter or year to year depending on a number of factors, including:

  .Our ability to attract and retain customers;

  .The level of consumer concern about the environment;

  .The timing of deregulation of the electric utility industry and changes in
   deregulation programs; and

   .Other factors discussed under other captions under "Risk Factors."

   Our limited operating history, together with the expansion of our business
strategy to include using our Web site to offer green consumer products other
than green electricity, also makes it difficult to fully assess the impact of
seasonal factors on our business. However, we expect to experience seasonality
in our business, reflecting a combination of seasonal fluctuations in Internet
usage, seasonal fluctuations of electricity usage and traditional retail
seasonality patterns. With respect to our existing retail electricity business,
higher than average use of electricity is expected in the summer and winter
months for Pennsylvania and California.

   Fluctuations in operating results may result in volatility of the price of
our common stock in the public market. It is likely that, from time to time in
the future, our operating results will be below the expectations of public
market analysts and investors. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."

   Intense Competition May Affect Our Ability To Grow Our Customer Base And
Generate Sales. Both the deregulated electricity and online commerce markets
are new, rapidly evolving and highly competitive. We face intense competition,
and many of our competitors and potential competitors have:

  .Longer operating histories;

  .Greater name recognition;

  .Larger customer bases; and

  .Greater financial and other resources.

   Competitors may enter the online commerce market easily and at relatively
little cost. In addition, our competitors, and competitors offering non-green
products in particular, may be able to devote significantly greater resources
than we can to the development and marketing of products. They may also be able
to offer better prices to our potential customers and make more attractive
offers to our potential strategic partners. We also anticipate competition from
other retailers attempting to offer a broad selection of green products. See
"Business--Our Competitive Position."

   Poor Performance By One Or More Of Our Outside Service Providers Could Be
Disruptive To Our Business Operations.  We rely on third-party service
providers for several key functions, including:

  .Web site development;

  .Mass media advertising;

                                       12

                                                                  Choose wisely.
<PAGE>

  .Direct mail marketing;

  .Inbound and outbound telephone marketing;

  .Mail response processing;

  .Customer fulfillment;

  .Billing and customer care; and

  .Information technology functions.

Any interruption in these third-party services, or a deterioration in their
service, could be disruptive to our business. Many of the agreements with our
third-party service providers are terminable upon short notice. If any of these
arrangements is terminated, we cannot assure you that we will be able to find
an alternative provider on a timely basis or on similar terms. In addition,
changes in providers may result in increased administrative costs. See
"Business--Marketing, Sales and Customer Service."

   Our Existing Green Electricity Business Depends On Our Ability To Obtain
From Wholesale Electricity Suppliers, On Acceptable Terms, Electricity Meeting
Our Customers' Requirements.  We do not generate electricity. For electricity
supply to serve the requirements of our green electricity customers, we
currently rely on short-term requirement contracts with wholesale electricity
suppliers. Under these contracts, our suppliers provide electricity, usually
for a one-year period, that matches the aggregate customer requirements that
are assigned to them. These contracts are not dependent on any minimum number
of customers being assigned to them and permit us to service customers
throughout a state. Under some of these contracts, the supplier can discontinue
the assignment of additional customers upon 90 days' notice. The wholesale
price is fixed or based upon a fixed price spread for the term of the
contracts. We attempt to reduce our risk related to fluctuations in wholesale
prices and customer usage by using these contracts, but cannot assure you that
price fluctuations will not adversely affect our business.

   We may be unable to obtain sufficient electric power to meet our future
supply needs, both for our existing operations in Pennsylvania and California
and future operations in new deregulated electricity markets that we are likely
to enter. We may be unable to extend or replace our existing supply contracts.
Moreover, any future supply contracts may not provide for a term or a price
comparable to those of our existing supply contracts and may not be
requirements contracts that enable us to reduce our risk relating to
fluctuations in wholesale prices and customer usage. In addition, specific
features of a deregulation program in any particular state may affect our
access to and the cost of supply arrangements for that state. See "Business--
Our Green Electricity Products."

   Our Ability To Grow Our Customer Base And Generate Sales Depends Upon Public
Environmental Consciousness. Our ability to grow our customer base and generate
revenues from the sale of green consumer products depends on the continued
development of public concern about environmental issues. While we believe that
such concern is rooted in improvements to education and the wider dissemination
of environmental information in recent years, we cannot assure you that these
trends will continue or that the current levels of environmental consciousness
will be sustained. Given our business plan, the failure of such concern to
continue to develop could materially and adversely affect the growth of our
customer base and sales revenues and, accordingly, our financial prospects.

   Potential Rapid Growth May Strain Our Human Resources. We have rapidly and
significantly expanded our operations, and future expansion will be required in
order for us to realize our business objectives. We have grown from 28
employees as of September 1, 1997 to 68 employees as of March 31, 1999, and our
operations have grown to serve approximately 68,000 electricity customers in
Pennsylvania and California as of March 31, 1999. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations." We expect that
future growth will place a significant strain on our managerial, operational
and financial resources. We must manage our growth through appropriate systems
and controls in each of these areas. We must also expand, train and manage our
workforce. There is intense competition for personnel in the areas of our
activities, and there can be no assurance that we will be able to continue to
attract and retain personnel with the qualifications necessary for the
development of our business.

                                       13

It's a small planet.(SM)
<PAGE>


   Our Business Operations Could Be Disrupted And Business Opportunities Lost
If We Are Unable To Integrate Our New Senior Executives And Retain An Able
Management Team. The operation of our business depends on our ability to grow,
integrate and retain an able management team. We recently hired a new Chief
Executive Officer, President and Chief Operating Officer, Chief Financial
Officer and Chief Technology Officer. We cannot assure you that we will
successfully integrate these and other new arrivals with our existing staff
without disruption to our business operations or that we will retain the
services of key personnel.

   Failure To Protect Our Intellectual Property Could Adversely Affect Our
Brand And Our Business. We rely on a combination of trademark and copyright
law, trade secret protection, confidentiality and license agreements with our
employees, strategic partners and others to protect our rights to our
intellectual property. We have filed applications to register some of our
service marks in the United States. Effective trademark, copyright and trade
secret protection may not be available in every country in which we intend
ultimately to offer our products. Despite our efforts, we cannot assure you
that our rights will be enforceable even if registered, and we may be unable to
deter misappropriation of our intellectual property. Misappropriation could
have a material adverse effect on our brand and our business by causing us to
lose customers and revenue opportunities. In addition, pursuing persons who
might misappropriate our intellectual property could be costly and divert the
attention of management from the operation of our business. See "Business--The
Protection of our Intellectual Property."

   Products Sold By Us May Subject Us To Litigation And The Related Costs. We
will sell products produced by others under the Green Mountain brand. We will
also have relationships with third parties who make their green products
available through our Web site. These sales and relationships may subject us to
liabilities, including consumer product liabilities. Defending against any such
claims could be costly and divert the attention of management from the
operation of our business. While we intend to require our suppliers and other
parties in these relationships to indemnify us against those types of
liabilities, any available indemnification may not be adequate. We currently
have product liability insurance coverage in the amount of $35 million, with a
$200,000 deductible per occurrence. Our liability insurance may not adequately
protect us against these types of liabilities.

   Claims Of Our Infringement On The Intellectual Property Rights Of Others
Could Be Costly And Disruptive To Our Business Operations.  Other parties may
assert infringement claims against us or claims that we have violated a patent
or infringed a copyright, trademark or other proprietary right belonging to
them directly or through the use of technology that we license from others.
Defending against any such claim could be costly and divert the attention of
management from the operation of our business. In addition, the inability to
obtain or maintain the use of licenses or other technology could adversely
affect our business operations.

   Year 2000 Complications Could Be Disruptive To Our Business Operations. On
January 1, 2000, many currently installed computer systems and software
products could fail or malfunction because they may not be able to distinguish
between 20th century dates and 21st century dates. We are subject to external
Year 2000-related failures or disruptions that might generally affect industry
and commerce, such as failures by energy generation or utility distribution
companies and related service interruptions. These failures or disruptions are
especially critical to us as a seller of retail electricity products.
Notwithstanding our Year 2000 efforts, the failure of our systems or those of
any of our information technology service providers, outsourcing partners or
suppliers, or the failure of the Internet generally, to be Year 2000 ready
could harm the operation of our systems or have unforeseen, material adverse
consequences to us. These consequences could include power supply interruptions
to our customers or the inability to bill our customers. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations--Year
2000 Readiness Disclosure."

   RISKS RELATED TO THE INTERNET AND ONLINE COMMERCE ASPECTS OF OUR BUSINESS

   Our Ability To Generate Sales Depends On Continued Growth Of Online
Commerce. Our ability to generate sales of green consumer products through our
Web site depends on continued growth in the use of the

                                       14

                                                                  Choose wisely.
<PAGE>

Internet and in the acceptance and volume of commerce transactions on the
Internet. We cannot assure you that the number of Internet users will continue
to grow or that commerce over the Internet will become more widespread or that
our sales will grow at a comparable rate. As is typical in the case of a new
and rapidly evolving industry, demand and market acceptance for recently
introduced services are subject to a high level of uncertainty. The Internet
may not prove to be a viable commercial marketplace for a number of reasons,
including:

  .Lack of acceptable security technologies;

  .Lack of access and ease of use;

  .Congestion of traffic;

  .Inconsistent quality of service and lack of availability of cost-
   effective, high-speed service;

  .Potentially inadequate development of the necessary infrastructure;

  .Governmental regulation; and

  .Uncertainty regarding intellectual property ownership.

We cannot assure you that the Internet will support increasing use or will
prove to be a viable commercial marketplace.

   We May Lose Customers And Revenue Opportunities If We Are Not Able To
Acquire Or Maintain An Effective Web Address. We currently hold the domain name
"greenmountain.com," as well as other related names. We may not be able to
prevent third parties from acquiring Web addresses that are similar to ours. If
that should occur, we could lose customers and revenue opportunities to those
third parties. Domain names generally are regulated by Internet regulatory
bodies and their designees. The regulation of domain names in the United States
and in foreign countries is subject to change. As a result, we may not acquire
or maintain the "greenmountain.com" domain name in all of the countries in
which we may conduct business in the future. Furthermore, the relationship
between regulations governing such addresses and laws protecting trademarks is
not clear.

   Failure Or Inadequate Performance Of Our Technology Systems May Interrupt
Our Operations And Result In The Loss Of Customers And Revenue
Opportunities. Our ability to grow our customer base and generate sales of our
green consumer products over the Internet will depend on the efficient and
uninterrupted operation of our Web-related technology systems that are required
to accommodate a high volume of traffic. We cannot assure you that our Web site
infrastructure will be able to accommodate the volume of traffic that could
develop or that upgrade requirements will not have an adverse impact on our
business. Although we intend to implement security measures, our systems will
be vulnerable to physical damage or interruption from human error, natural
disasters, telecommunication failures, break-ins, sabotage, computer viruses,
intentional acts of vandalism and similar events. We do not intend to have
redundant systems and have not adopted a formal disaster recovery plan.
Therefore, any system failure, including network, software or hardware failure,
that causes an interruption in our service or a decrease in responsiveness of
our Web site could cause us to lose customers and revenue opportunities and
could harm our reputation and brand. In addition, our business interruption
insurance may not compensate us for all losses that could occur as a result of
system failures.

   Security Concerns Could Hinder Our Online Sales And May Require Significant
Expenditures. Concern about the transmission of confidential information over
the Internet has been a significant barrier to online commerce over the
Internet. We cannot assure you that consumers will not limit their use of the
Internet to purchase products because of security concerns. We rely on
encryption and authentication technology licensed from third parties to provide
the security and authentication necessary to effect secure transmission of
confidential information, such as customer credit card numbers. We cannot
assure you that advances in computer capabilities, new discoveries in the field
of cryptography or other events or developments will not result in a compromise
or breach of the security measures that we use to protect customer transaction
data. In addition, we may be required to make significant expenditures to
protect against the threat of security breaches or to alleviate problems caused
by such breaches.

   Information Displayed On Our Web Site May Subject Us To Litigation And The
Related Costs. We may be subject to claims for defamation, libel, copyright or
trademark infringement or based on other theories relating to information
published on our Web site. We could also be subject to claims based upon the
content that is accessible from our Web site through links to other Web sites.
Defending against any such claims could be costly and divert the attention of
management from the operation of our business.

   Government Regulation Of The Internet And Online Commerce Is Still
Developing And Could Increase Our Operating Costs Or Otherwise Adversely Affect
Our Business. There are existing laws and regulations that specifically
regulate communications or commerce on the Internet. Further, laws and
regulations that address issues such as user privacy, pricing, content,
taxation and the characteristics and quality of online products and services
are under consideration by federal, state, local and foreign governments and
agencies. New laws or regulations relating to the Internet, or new applications
or interpretations of existing laws, could adversely affect our business by
increasing our operating costs or otherwise.

   RISKS RELATED TO THIS OFFERING

   Our Existing Stockholders Will Exercise Significant Control And Could Make
Decisions That Adversely Affect New Investors. We expect that the Wyly family
will continue to exercise significant control over our direction and management
following the closing of this offering. In addition, our directors and
executive officers and their affiliates will, in the aggregate, own
approximately 9.3% of the outstanding shares of GreenMountain.com common stock
upon the closing of this offering, or 8.7% if the underwriters exercise their
over-allotment option in full. As a result of their share ownership, these
stockholders will have a significant influence on all matters requiring
stockholder approval, including the election of directors. This concentration
of ownership could delay or prevent another person from acquiring control or
causing a change in control of GreenMountain.com, which may affect your ability
to resell your shares at a favorable price. See "Principal Stockholders."

   Our Shares Have Never Been Publicly Traded And A Public Market May Not
Develop Or Be Liquid. Prior to this offering, there has been no public market
for our common stock. We cannot predict the extent to which a trading market
will develop or how liquid that market might become. The initial public
offering price for the shares will be determined by negotiations between us and
the representative of the underwriters and may not be indicative of prices that
will prevail in the trading market following this offering. See "Underwriting."

   Our Stock Price Is Likely To Be Volatile And This Volatility Could Affect
Your Ability To Resell Your Shares At A Profit. The trading price of our common
stock is likely to be volatile. The stock market has experienced significant
price and volume fluctuations, and the market prices of technology company
stocks, particularly those of Internet-related companies, have been highly
volatile. As a result, you may not be able to resell your shares at a price
equal to or greater than the initial public offering price. In the past,
following periods of volatility in the market price of a company's securities,
securities class action litigation has often been instituted against the
issuing company, resulting in substantial costs and a diversion of management's
attention from the operation of its business. See "Underwriting."

   Shares Eligible For Future Sale By Our Existing Stockholders May Adversely
Affect Our Stock Price. The market price of our common stock could drop due to
the sales of a large number of shares of our common stock or the perception
that such sales could occur. These factors could also make it more difficult to
raise funds through future offerings of common stock. After this offering,
50,546,500 shares of common stock will be outstanding. Of these shares, the
25,000,000 shares sold in this offering will be freely tradeable without
restrictions under the Securities Act of 1933, except for any shares purchased
by our "affiliates," as defined in Rule 144 under the Securities Act. The
number of shares of common stock outstanding would increase to 54,296,500 and
the number of freely tradeable shares would increase to 28,750,000 if the
underwriters exercise their over-allotment option in full. Our officers and
directors and

stockholders holding in the aggregate 25,464,000 outstanding shares of common
stock have entered into lock-up agreements pursuant to which they have agreed
not to offer or sell any shares of common stock for a period of 180 days after
the date of this prospectus without the prior written consent of Prudential
Securities, on behalf of the underwriters. Also, Prudential Securities may, at
any time and without notice, waive the terms of these lock-up agreements as
specified in the underwriting agreement. Upon expiration of this lock-up
period, the shares owned by these persons prior to completion of this offering
may be sold into the public market without registration under the Securities
Act in compliance with the volume limitations and other applicable restrictions
of Rule 144 under the Securities Act. After the date of this prospectus, we
intend to file one or more registration statements under the Securities Act to
register all shares of common stock issuable upon the exercise of outstanding
stock options or reserved for issuance under our 1999 Stock Option Plan and all
shares of common stock reserved for issuance under our 1999 Director Stock
Award Plan. Those registration statements are expected to become effective
immediately upon filing, and subject to the vesting requirements and exercise
of the related options and the grant of stock awards (as well as the terms of
the lock-up agreements), shares covered by those registration statements will
be eligible for sale in the public markets, except for any shares held by our
"affiliates." See "Shares Eligible for Future Sale."

   Investors Will Experience Immediate And Substantial Dilution And May
Experience Further Dilution. The initial public offering price of the common
stock in this offering will be substantially higher than the net tangible book
value per share of the common stock immediately after this offering. Therefore,
if you purchase shares of common stock in this offering, you will incur
immediate and substantial dilution of $6.19 per share in the net tangible book
value per share of common stock from the price you paid, assuming an initial
public offering price of $12.00 per share. The exercise prices of most of our
outstanding options are below the anticipated initial public offering price. To
the extent these options are exercised, you will experience further dilution.
See "Dilution."

   Our Management Will Have Broad Discretion In Use Of Proceeds And It May Not
Effectively Utilize Those Funds. Our management will have broad discretion in
how we use the net proceeds of this offering. Investors will be relying on the
judgment of our management regarding the application of the net proceeds of
this offering. Our management's decision regarding use of the net proceeds may
not be the most effective utilization of those funds. See "Use of Proceeds."

   Provisions In Our Governing Documents And Delaware Law Could Make
Transactions Beneficial To Our Stockholders More Difficult. Provisions of our
certificate of incorporation, our bylaws and Delaware law could make it more
difficult for a third party to acquire us, even if doing so would be beneficial
to our stockholders. See "Description of Capital Stock."

                           FORWARD-LOOKING STATEMENTS

   This prospectus includes forward-looking statements based largely on our
current expectations and projections about future events and financial trends
affecting the financial condition of our business. The words "believe," "may,"
"will," "estimate," "continue," "anticipate," "intend," "expect" and similar
expressions identify these forward-looking statements. These forward-looking
statements are subject to a number of risks, uncertainties and assumptions,
including those described above under the caption "Risk Factors." In light of
these risks and uncertainties, the forward-looking events and circumstances
discussed in this prospectus may not occur and actual results could differ
materially from those anticipated in the forward-looking statements. We
undertake no obligation to publicly update or revise any forward-looking
statements, whether as a result of new information, future events or otherwise.

                                USE OF PROCEEDS

   We estimate that the net proceeds to GreenMountain.com from the sale of the
common stock in this offering, assuming an initial public offering price of
$12.00 per share, will be $277,625,000, after deducting underwriting discounts
and commissions and estimated offering expenses. The estimated net proceeds
would increase to $319,643,750 if the underwriters exercise their over-
allotment option in full.

   The principal purpose of this offering is to obtain funds to be used as
working capital and for general corporate purposes. We currently anticipate
that we will use approximately 50% to 60% of the net proceeds for brand
awareness and marketing, 10% to 20% of the net proceeds for technology and
development, and 25% to 35% of the net proceeds for other general corporate
purposes, including acquisitions of or investments in strategic businesses or
technologies. We cannot assure you, however, that the amount of the net
proceeds of this offering actually applied for any particular use will not
differ from the amount we currently expect to use for that purpose.

   As part of our general corporate purpose spending, we expect to allocate an
amount equal to 2% to 6% of the net proceeds to make substantial contributions
to the political process and for public education. The purpose of these
expenditures will be to help accelerate the deregulation of the electric
utility industry and to help impose on the sources of industrial air pollution
the costs of their pollution.

   We currently have no commitments or agreements relating to any acquisition
or investment in any strategic business or technologies. We are, however,
exploring, and expect from time to time in the future to explore, possible
acquisitions or investments that would further our business objectives.

   If prior to the closing of this offering we have obtained advances from
Green Funding I, L.L.C., an investment vehicle managed by the Wyly family, to
permit us to meet our working capital requirements, we will use a portion of
the net proceeds to repay the advances in full. There are currently no amounts
outstanding under our funding agreement with Green Funding I. However, we may
obtain advances under that agreement prior to the closing of this offering. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Related Party Transactions--Subsequent Transactions--Working
Capital Funding Commitment."

   As of the date of this prospectus, we cannot specify, other than as
indicated above, the particular uses for the net proceeds to be received upon
the closing of this offering. Accordingly, our management will have broad
discretion in the application of the net proceeds. See "Risk Factors--Risks
Related to this Offering--Our Management Will Have Broad Discretion in Use of
Proceeds and It May Not Effectively Utilize Those Funds."

   Pending these uses, the net proceeds of this offering will be invested in
short-term, interest-bearing, investment-grade securities or guaranteed
obligations of the U.S. Government.

                                DIVIDEND POLICY

   We have not declared or paid any cash dividends on our common stock, and we
do not anticipate declaring or paying any cash dividends on our common stock in
the foreseeable future. We intend to retain any future earnings for use in the
operation of our business.

   The number of shares of common stock reflected as issued in the table above,
both on an actual basis and on an adjusted basis, does not reflect shares that
may be issued upon the exercise of options or warrants. You should be aware
that we are permitted, and in some cases obligated, to issue additional shares
of common stock. If and when we issue these shares, the percentage of the
common stock you own may be diluted. The following is a summary of additional
shares of common stock that may be issued pursuant to the underwriters' over-
allotment option and that we have currently approved, or we expect to approve,
for issuance upon the exercise of options and warrants or grant of stock awards
after this offering:

  . 3,750,000 shares issuable upon the exercise of the underwriters' over-
    allotment option;

  . 6,200,229 shares issuable upon the exercise of the options outstanding as
    of the date of this prospectus;

    awarded under our 1999 Stock Option Plan in the future, including an
    option to purchase 625,000 shares of common stock expected to be granted
    to Sam Wyly, an option to purchase 487,500 shares of common stock
    expected to be granted to Dennis Crumpler and an option to purchase

                                    DILUTION

   Purchasers of the common stock in this offering will experience immediate
and substantial dilution in the net tangible book value of the common stock
from the initial public offering price. Net tangible book value represents the
amount of our total tangible assets less our total liabilities, divided by the
number of shares of common stock outstanding.

  .At March 31, 1999, our net tangible book value was $16,194,862 or $0.63
   per share on an actual basis, but reflecting our conversion from a limited
   liability company to a corporation as if that conversion had occurred as
   of March 31, 1999.

  .After giving effect to the sale of the 25,000,000 shares of common stock
   offered in this offering at an assumed initial public offering price of
   $12.00 per share and after deducting underwriting discounts and
   commissions and estimated offering expenses, as if this offering had been
   completed as of March 31, 1999, our pro forma net tangible book value on
   March 31, 1999 would have been $293,819,862 or $5.81 per share.

   This represents an immediate increase in the net tangible book value of
approximately $5.20 per share to our existing stockholders and an immediate and
substantial dilution of $6.17 per share to new investors purchasing common
stock in this offering. The following table illustrates this per-share
dilution:

an option to purchase 675,000 shares of common stock, in each case at an
exercise price per share equal to the initial public offering price.

   To the extent any options having an exercise price lower than the initial

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS

   The following discussion should be read in conjunction with the financial
statements and the notes to those statements included elsewhere in this
prospectus. The following discussion contains forward-looking statements that
reflect our plans, estimates and beliefs. Our actual results could differ
materially from those discussed in these forward-looking statements. Factors
that could cause or contribute to such differences include, but are not limited
to, those discussed below and elsewhere in this prospectus, particularly in
"Risk Factors."

Overview

   We were formed as a limited liability company in February 1997. Prior to the
closing of this offering, we will convert from a limited liability company to a
corporation. See "Related Party Transactions-- Reorganization Transaction."

   Between August 1997 and March 31, 1998, Green Funding I and Green Funding
II, investment vehicles managed by the Wyly family, contributed to us a total
of $70.0 million. In August 1997, as required under the limited liability
company agreement, Green Mountain Power Corporation, through a subsidiary,
contributed to us

  .service marks, including our Choose wisely. It's a small planet.SM and
   Green Mountain Energy ResourcesSM service marks,

  .research conducted by Green Mountain Power Corporation prior to formation
   of the limited liability company to evaluate the viability of a
   nationally-marketed, premium priced green electricity product, including
   marketing studies and analyses and

  .rights under agreements with third-party service providers,

which collectively were valued at $4.0 million, in exchange for an equity
interest in the limited liability company of 33%, after the effect of the
return of capital discussed below. In accordance with the limited liability
company agreement, the $4.0 million value associated with Green Mountain Power
Corporation's initial capital contribution was credited to the subsidiary's
capital account. In August 1997, Green Funding I contributed $8.0 million and
committed to contribute an additional $22.0 million in exchange for a 67%
equity interest. Immediately following the initial contribution by Green
Funding I, as required under the limited liability company agreement the
subsidiary of Green Mountain Power Corporation received a distribution from the
limited liability company of $4.0 million, representing reimbursement for the
cost of market studies and analyses and other development costs incurred by
Green Mountain Power Corporation prior to the formation of the limited
liability company. By December 1998, as a result of capital contributions made
by Green Funding I after August 1997, the equity interest owned indirectly by
Green Mountain Power Corporation had been diluted to approximately 1%. In late
December 1998, we negotiated with Green Mountain Power Corporation and agreed
to pay the subsidiary of Green Mountain Power Corporation $1.0 million in cash,
the management committee's estimate of the fair value, for its remaining 1%
equity interest, a non-compete agreement, rights to the Green Mountain name and
other concessions. This agreement enabled us to eliminate our ties to a
traditional regulated utility that had elected not to contribute additional
equity to us. In addition, this agreement includes provisions favorable to us
relating to non-competition and the use of the Green Mountain name. During
January and February 1999, we raised $35.2 million in cash through private
equity offerings. See "Related Party Transactions--Subsequent Transactions,"
"Principal Stockholders" and Notes (1) and (11) to our financial statements
included elsewhere in this prospectus.

   Since commencing active operations in August 1997, we have:

  .Established relationships with several outsourcing partners to perform
   most of the marketing, sales and customer service functions necessary for
   the operation of our business;

  .Established relationships with environmental groups and entered into
   affinity marketing programs with some of them;

                                       22

                                                                  Choose wisely.
<PAGE>

  .Designed and built our Information Network to provide for the efficient
   communication of information with and among our outsourcing partners;

  .Integrated our Web site into our Information Network to enable consumers
   to purchase our electricity products online;

  .Implemented an aggressive marketing campaign using the Internet and other
   media aimed at creating awareness of the Green Mountain brand in
   California, which opened for competition on April 1, 1998, and
   Pennsylvania, which opened for competition on January 1, 1999;

  .Established supply relationships for green electricity in California and
   Pennsylvania;

  .Commenced marketing green electricity to residential customers in the
   deregulated electric utility markets of California and Pennsylvania;

  .Established supply relationships for Green Mountain SolarSM systems and
   commenced marketing them in California and Pennsylvania; and

  .Recruited a management team with substantial expertise in brand
   development and marketing, as well as Internet-related technologies.

   As of March 31, 1999, we were serving approximately 19,900 customers in
California. We began selling electricity products in Pennsylvania on January 1,
1999. As of March 31, 1999, we were serving approximately 48,100 customers in
Pennsylvania.

   We had 28 employees as of September 1, 1997. As of March 31, 1999, we had 68
employees, including management and staff personnel, and an additional seven
temporary employees. We will add additional management and staff personnel as
necessary, but we expect to continue to rely heavily on outsourcing
arrangements.

   We have only a limited operating history upon which you can evaluate our
business and prospects. We have not achieved profitability, and expect to incur
net losses in 1999 and subsequent fiscal periods. We expect our costs of sales
and operating expenses, especially in the areas of sales, marketing and brand
promotion, to increase significantly, and, as a result, will need to generate
significant revenues to achieve profitability. Even if we do achieve
profitability, we may be unable to sustain or increase profitability on a
quarterly or annual basis in the future. We believe that period-to-period
comparisons of our operating results are not meaningful and that results for
any particular period should not be relied on as an indication of future
performance. See "Risk Factors."

Results Of Operations--Year Ended December 31, 1998 Compared To The Year Ended
December 31, 1997

  Revenues And Cost Of Sales

   We did not generate revenues until the last half of 1998. Revenues increased
from zero in 1997 to $1.5 million in 1998. Cost of sales representing
electricity wholesale costs increased from zero in 1997 to $1.1 million in
1998. These increases were attributable to the commencement of electric service
to customers in California beginning April 1, 1998.

  Customer And Regional Operations Expense

   Customer and regional operations expense increased by $3.8 million from $1.0
million to $4.8 million from 1997 to 1998. This expense is comprised primarily
of the cost of our billing and customer care operations and expenses incurred
for operations within particular states, including general operating expenses,
supply personnel, legal and regulatory expenses and consulting and lobbying
expenses. Overall, the increase from 1997 to 1998 primarily represents:

  .Approximately a $1.5 million increase attributable to the commencement of
   billing activity when the California retail electricity market opened for
   competition;

                                       23

It's a small planet.(SM)
<PAGE>

  .Approximately a $0.9 million increase in regional operating activities
   within states expected to open their electric utility markets for retail
   competition in the foreseeable future;

  .The preparation for commencement of service to customers in Pennsylvania
   on January 1, 1999; and

  .Costs associated with increased business development efforts.

   In 1998, we entered into two electricity supply agreements to serve our
customers in California, and we entered into three electricity supply
agreements to cover anticipated customer requirements in Pennsylvania to
commence in 1999.

  Sales And Marketing Expense

   Sales and marketing expense increased by $28.7 million from $4.3 million to
$33.0 million from 1997 to 1998. Our sales and marketing expenses consist
primarily of payroll and the costs related to (1) building brand awareness,
including traditional media advertising, such as television, radio, print and
billboards, and special events and promotions and (2) direct marketing,
including direct mail, affinity programs, Internet and inbound and outbound
telemarketing. Total sales and marketing costs included the following amounts:

  .  Approximately $10.0 million for the year ended December 31, 1998 and
     $0.7 million for the period from inception on February 26, 1997 through
     December 31, 1997 for building brand awareness; and

  .  Approximately $17.4 million for the year ended December 31, 1998 and
     $2.4 million for the period from inception on February 26, 1997 through
     December 31, 1997 for direct marketing costs in Pennsylvania and
     California.

These increases are primarily attributable to the commencement of service in
California in April 1998 and the anticipation of the commencement of service in
Pennsylvania effective January 1, 1999. These increases involve our use of
marketing services from The Cullinan Group in 1998. We expect sales and
marketing expense to continue to increase as we expand our green electricity
business to additional states and expand the products offered through our Web
site.

  General And Administrative Expense

   General and administrative expenses increased $2.5 million from $1.7 million
to $4.2 million from 1997 to 1998. This expense is comprised primarily of
payroll and miscellaneous expenses relating to our administrative, human
resources, finance, legal and regulatory functions. Total payroll costs
included in general and administrative expense were approximately $2.8 million
for the year ended December 31, 1998 and $1.1 million for the period from
inception on February 26, 1997 through December 31, 1997. The increase in
payroll costs reflects the increase in the number of employees needed to
accommodate our growth in 1998. Total miscellaneous costs related to our
administrative, human resources, finance, legal and regulatory functions were
approximately $1.4 million for the year ended December 31, 1998 and $0.6
million for the period from inception on February 26, 1997 through December 31,
1997. Miscellaneous costs primarily included costs related to travel, office
supplies and meals and entertainment due to costs incurred for activities
supporting the entry into deregulated electric utility markets.

  Technology And Development Expense

   Technology and development expense increased $0.9 million from $2.0 million
to $2.9 million from 1997 to 1998. This expense is comprised primarily of
payroll, general operating expenses and costs of consultants relating to the
preliminary development and operation of our information technology systems.
The increase in this expense primarily relates to information technology
consulting services provided by Sterling Software. The increase was also
partially attributable to increased payroll and general operating costs related
to operating in 1998 for a full year rather than less than six months in 1997.
We anticipate this expense will increase in future periods as we continue to
implement improvements in our Web site and our Information Network.

                                       24

                                                                  Choose wisely.
<PAGE>

  Depreciation And Amortization

   Depreciation and amortization increased $0.7 million from $0.1 million to
$0.8 million from 1997 to 1998. Our first full year of operations was 1998.
Depreciation and amortization for 1998 represent one full year, while
depreciation and amortization for 1997 represents a period from commencement of
operations in August 1997 to December 31, 1997. This increase is also due to
$0.9 million of property and equipment additions during 1998.

  Organizational Costs

   Organizational costs decreased $4.0 million from $4.7 million to $0.7
million from 1997 to 1998. In 1997, these costs were comprised primarily of
start-up and organizational development costs of approximately $4.0 million.
Unamortized organization costs in the amount of $0.3 million were written off
in the fourth quarter of 1998, in accordance with a new accounting
pronouncement.

  Interest Income/(Expense), Net

   Interest income/(expense), net, increased $0.1 million from 1997 to 1998
resulting primarily from interest on cash and cash equivalents offset in part
by interest expense on a short-term, $10.0 million loan. This loan was both
obtained and repaid in 1998. Our operations have been funded almost exclusively
by capital contributions.

  Income Tax Expense

   No benefit for federal and state income taxes is reported in our financial
statements because we have elected to be taxed as a partnership prior to our
conversion from a limited liability company to a corporation. For the periods
presented, the federal and state tax effects of our tax losses were the
responsibility of Green Funding I as a member of the limited liability company
in accordance with our limited liability company agreement. Subsequent to our
conversion into a corporation, we will account for income taxes in accordance
with Statement of Financial Accounting Standards (SFAS) No. 109, Accounting for
Income Taxes. If we had applied this statement for the period from our
inception through December 31, 1998, the deferred tax asset generated,
primarily from net operating loss carry forwards, would have been offset by a
full valuation allowance.

Results Of Operations--Three Months Ended March 31, 1999 Compared To The Three
Months Ended March 31, 1998

  Revenues And Cost Of Sales

   Revenues increased from zero in the first quarter of 1998 to $4.1 million in
the first quarter of 1999. Cost of sales increased from zero in the first
quarter of 1998 to $3.1 million in the first quarter of 1999. The increase was
attributable to the commencement of electric service to customers in
Pennsylvania and California.

  Customer And Regional Operations Expense

   Customer and regional operations expense increased by $1.6 million from $0.7
million to $2.3 million from the first quarter of 1998 to the first quarter of
1999. The increase primarily represents:

  .  Approximately a $0.7 million increase attributable to the commencement
     of billing activity when the Pennsylvania retail electricity market
     opened for competition on January 1, 1999;

  .  Approximately a $0.7 million increase in regional operating expenses
     within states expected to open their electric utility markets for retail
     competition in the foreseeable future; and

  .  Costs associated with increased business development efforts.

                                       25

<PAGE>

  Sales And Marketing Expense

   Sales and marketing expense increased by $8.3 million from $4.1 million to
$12.4 million from the first quarter of 1998 to the first quarter of 1999. Our
sales and marketing expenses consist primarily of payroll and the costs related
to (1) building brand awareness, including traditional media advertising, such
as television, radio, print and billboards, and special events and promotions
and (2) direct marketing, including direct mail, affinity programs, Internet
and inbound and outbound telemarketing. Total sales and marketing costs
included the following amounts:


  .  Approximately $3.7 million for the quarter ended March 31, 1999 and $0.8
     million for the quarter ended March 31, 1998, for building brand
     awareness; and

  .  Approximately $5.7 million for the quarter ended March 31, 1999 and $2.6
     million for the quarter ended March 31, 1998, for direct marketing costs
     in Pennsylvania and California;

These increases are primarily attributable to the commencement of service in
Pennsylvania effective January 1, 1999. These increases as discussed above
involve our use of marketing services from The Cullinan Group. The first
quarter of 1999 amounts also reflect approximately $0.4 million of compensation
expense associated with the difference between the purchase price and exercise
price of shares and options issued and their fair market value at the date of
sale or grant. We expect sales and marketing expense to continue to increase as
we expand our green electricity business to additional states and expand the
products offered through our Web site.

  General And Administrative Expense

   General and administrative expenses increased $2.9 million from $1.0 million
for the first quarter of 1998 to $3.9 million for the first quarter of 1999.
This expense is comprised primarily of payroll and miscellaneous expenses
relating to our administrative, human resources, financial, legal and
regulatory functions. Total payroll costs included in general and
administrative expense were approximately $2.5 million for the first quarter of
1999 and $0.7 million for the first quarter of 1998. Total general and
administrative expense for the first quarter of 1999 reflects the recording of
approximately $2.1 million of compensation expense associated with the
difference between the purchase price and the exercise price of shares and
options issued and their fair market value at the date of sale or grant. We
charged $1.5 million of the total compensation expense to payroll expenses and
$0.6 million to consulting expenses. Total miscellaneous costs related to our
administrative, human resources, finance, legal and regulatory functions were
approximately $1.4 million for the first quarter of 1999 and $0.3 million for
the first quarter of 1998. Miscellaneous costs primarily included costs related
to travel, office supplies and meals and entertainment.

  Technology And Development Expense

   Technology and development expense increased $1.5 million from $0.8 million
for the first quarter of 1998 to $2.3 million for the first quarter of 1999.
This expense is comprised primarily of payroll, general operating expenses and
costs of consultants relating to the preliminary development and operation of
our information technology systems and our Web site. The increase in this
expense was primarily attributable to increased payroll and general operating
costs related to increased consultant services for current operations provided
by Sterling Software and increased network development. We anticipate this
expense will increase in future periods as we continue to implement
improvements in our Web site and our Information Network.

  Depreciation And Amortization

   Depreciation and amortization for the first quarter of 1999 remained
consistent with the first quarter of 1998. Capitalized assets include primarily
computers and furniture and fixtures that were purchased when we commenced
operations.

                                       26

                                                                  Choose wisely.
<PAGE>

  Interest Income/(Expense), Net

   The increase in interest income/(expense), net, of $0.2 million from the
first quarter 1998 to the first quarter 1999 resulted primarily from interest
earned on cash and cash equivalents as a result of our equity offerings in
January and February of 1999.

Liquidity And Capital Resources

   Our operations have been funded almost entirely using proceeds raised
through the sale of equity interests.

   Net cash used in operating activities was $12.3 million for 1997, $39.9
million for 1998, $5.1 million for the first quarter of 1998 and $19.1 million
for the first quarter of 1999. The period-to-period increases in net cash used
in operating activities resulted primarily from increasing net losses,
partially offset by increases in accrued expenses and accounts payable.

   Net cash used in investing activities was $1.3 million for 1997, $0.8
million for 1998, $0.1 million for the first quarter of 1998 and $0.2 million
for the first quarter of 1999, entirely the result of purchases of property
and equipment, primarily computer equipment and furniture and fixtures.

   Net cash provided by financing activities was $15.6 million for 1997 and
$44.4 million for 1998. Net cash provided by financing activities in both 1997
and 1998 resulted primarily from capital contributions by Green Funding I.
During the first quarter of 1999, we raised $35.2 million of cash through
private equity offerings.

   We are seeking additional investors through this offering to obtain working
capital for brand development and marketing, product development, enhancement
to our Web site and technology systems, expansion of our green electricity
business into new deregulated markets, environmental programs and other
general corporate purposes. The implementation of our expanded business plan
is dependent on this offering. Although we have no material commitments for
capital expenditures, we anticipate a substantial increase in our capital
expenditures and lease commitments consistent with anticipated growth in
operations, infrastructure and personnel. These expenditures will primarily be
for computer equipment, furniture and fixtures and leasehold improvements. We
also have total minimum lease obligations of $0.4 million under cancelable
operating leases. Several of our outsourcing agreements have minimum financial
commitments as follows:

  .  Our outsourcing agreement with en.able, L.L.C. currently commits us to
     pay minimum monthly service charges for call center service and billing
     services in the amount of $112,500;

  .  Our teleservices agreement with ICT Group, Inc., which we may terminate
     on 30 days' notice, commits us to pay fixed monthly fees of
     approximately $8,700, as well as actual costs associated with service
     representatives' time and communication costs incurred resulting from
     inbound and outbound calls;

  .  Our marketing services agreement with The Cullinan Group requires us to
     pay a minimum monthly retainer fee of $30,000 as well as monthly advance
     payments in the amount of anticipated expenses less the monthly retainer
     fee; and

  .  Our marketing agreement with Yahoo! Inc. commits us to pay approximately
     $6,000,000 over the one-year term of the contract commencing in May
     1999, as well as payment of referral fees, not to exceed $400,000 in the
     aggregate, for new energy services accounts opened as a result of the
     Yahoo! promotions. Expenses, including referral fees, will be recognized
     under this contract throughout the term of the contract and in a manner
     consistent with receipt of services provided by Yahoo!

   Our contracts with four electricity suppliers provide for separate letters
of credit or equivalent financial assurances to satisfy credit requirements.
The amounts of the letters of credit range from 15 days' to two months' of
receivables based on our load forecast. In addition, we have delivered to one
electricity supplier irrevocable letters of credit in association with the
supplier's purchase and installation of three wind power

                                      27

turbines. We also delivered letters of credit to regulators securing our
performance as an energy service provider. Total supply and regulatory letters
of credit outstanding at December 31, 1998 were $2,765,230 and at March 31,
1999 were $2,477,251.

   If we are unable to obtain financing through this offering, we will curtail
our current growth plans and we believe our existing cash resources, together
with up to $22.0 million available under a funding agreement with Green Funding
I, will be sufficient to fund our operations at least through 1999. There are
currently no amounts outstanding under the funding agreement. However, we may
obtain advances under that agreement prior to the closing of this offering. See
"Related Party Transactions--Subsequent Transactions--Working Capital Funding
Commitment" and Note (1) to our financial statements included elsewhere in the
prospectus. We believe that, assuming this offering closes, the net proceeds
from the offering, together with cash resources, will be sufficient to meet our
anticipated cash needs for working capital and capital expenditures for the
foreseeable future. However, there may arise circumstances in which we need to
raise additional funds through public or private financings or other
arrangements, and we cannot assure you that we will be able to do so. The
failure to raise additional funds when needed could have a material adverse
effect on our business, results of operations and financial condition.

Market Risk Disclosures

   We currently have no indebtedness, hold no derivative instruments and do not
earn foreign-sourced income. Accordingly, changes in interest rates or currency
exchange rates do not generally have a direct effect on our financial position.
Our commodity price risk is limited, as our electricity supply contracts are
generally short-term requirements contracts that match the aggregate customer
requirements that are assigned to them and they were not entered into for
trading or speculative purposes. Under some of these contracts, either we or
our suppliers can discontinue the assignment of additional customers with
advance notice. The wholesale price is either fixed or includes a fixed margin
to the wholesale clearing price for the term of the contracts. In the future,
as our electricity requirements reach substantial levels, we may increase the
volume of electricity contracts that we buy directly from electricity
wholesalers other than under requirements contracts in order to reduce our
overall costs of electricity supply and allow us greater marketing flexibility.

   As of March 31, 1999, we did not face the level of equity price risk that we
expect to be subject to subsequent to this offering. To the extent that changes
in interest rates and currency exchange rates affect general economic
conditions, we would be affected by such changes.

Year 2000 Readiness Disclosure

  State Of Readiness

   On January 1, 2000, technology systems and software applications may fail or
malfunction due to the inability to distinguish between 20th century dates and
21st century dates. We have defined "Year 2000 readiness" or "Year 2000 ready"
as meaning a hardware or software system is suitable for continued use into the
Year 2000 and beyond. Specifically, date dependant systems may represent the
year 2001 as "01," but will not cease to perform the functions necessary for
its use.

   We have determined during our initial assessment that our internal corporate
systems, including both hardware and software applications, are Year 2000
ready, with some exceptions. Those systems determined not to be Year 2000 ready
and which are critical to our operations will either be replaced or upgraded in
order to be Year 2000 ready. We expect to achieve Year 2000 readiness for all
of our systems by the end of the third quarter of 1999. The phases of our Year
2000 readiness program are as follows: (1) Planning and Awareness,
(2) Assessment, and (3) Remediation and Testing.

  .  Our Planning and Awareness phase includes the creation and maintenance
     of an area of our Web site to present Year 2000 contact information,
     links to additional sites and GreenMountain.com Year 2000 statements.

                                       28

                                                                  Choose wisely.
<PAGE>


   Employee awareness consists of company newsletters, Intranet/extranet
   pages, inter-office bulletins and staff meeting updates. Partners and
   suppliers will receive mailings, Year 2000 surveys and telephone calls,
   and, if appropriate, site-visits. This phase is currently approximately
   80% complete and is expected to be completed by the end of the third
   quarter of 1999.

  . The overall Assessment phase includes risk assessment within three areas
    of our business: corporate operations, business partners and wholesale
    power suppliers. Risks will be ranked by low, medium and high depending
    on their perceived impact to our business. Corporate inventory is
    included in this phase to determine all components that comprise the
    corporate information systems and building mechanical systems (including
    heating, ventilation, air conditioning and security). Questionnaires and
    telephone calls, visits to Web sites and requests for readiness
    disclosures will be used to determine the initial state of readiness and
    Year 2000 preparations of all parties external to GreenMountain.com. As
    part of Assessment, inventory is approximately 30% complete overall, with
    internal corporate systems inventory approximately 40% complete and
    outsourced business systems inventory approximately 20% complete. Year
    2000 readiness of corporate systems is substantially complete due to the
    fact that we use current software and have no proprietary systems. We
    have been researching Web sites of the manufacturers of our corporate
    systems and have found that with the installation of patches or service
    packs, this software is already ready or will be ready by the end of
    1999. The internal figure will increase significantly when the
    implementation of Microsoft SMS, a package which will assist us in
    assessing our Year 2000 readiness, is complete. The percentage of
    outsourced business systems inventory will increase significantly when we
    receive the feedback to our inquiries on vendor and partner Year 2000
    readiness in response to the systems they employ to meet our
    requirements. We expect the overall Assessment phase to be completed by
    the end of the second quarter of 1999.

  . Remediation and Testing of corporate systems includes using Microsoft SMS
    to continue to ensure ongoing Year 2000 readiness of corporate systems
    and software, working with vendors on building mechanical systems and
    testing of Year 2000 readiness of applications, such as our financial
    package and payroll system. Supplier remediation and testing involves the
    testing of transactions across our vendor/partner network. This phase is
    currently approximately one-third complete for corporate internal
    systems' remediation and we expect to complete all remediation no later
    than the beginning of the fourth quarter of 1999.

   In addition to building mechanical systems, we distinguish technology
systems into two categories, business systems and corporate systems. The
business systems consist of the hardware and software employed to support the
business operations of GreenMountain.com, including third-party service
providers. The corporate systems consist of the hardware and software required
to support the corporate infrastructure such as our network servers, desktop
computers, desktop applications and the financial system.

  . For business systems, we have outsourced the majority of our operations.
    We have relationships with electricity suppliers, local utility
    distribution companies, billing centers, call centers, customer
    acquisition, mailing list providers, Web content providers, network
    managers, and marketing groups. We have begun research into the state of
    Year 2000 readiness with each of the organizations we do business with.
    We believe we have a level of comfort that each will be able to continue
    functioning and fulfilling their obligations to us. To formalize this, we
    are in the process of preparing material to be sent to each supplier
    asking them to certify that the equipment and software they employ to
    meet their contractual obligations to us has been tested and will be
    suitable for continued use into the Year 2000 and beyond. Additionally,
    we will be reviewing the business sustainability of our key suppliers of
    billing and customer care and some of their information technology
    functions. Lastly, our network manager service provider will be assisting
    in the coordination of a system level test plan that will push and pull
    transactions across our network to and from our different suppliers and
    partners. The test data will be designed to test transactions with key
    dates aimed at confirming Year 2000 readiness. We expect to complete the
    mailing, review of business sustainability and testing by the end of the
    third quarter of 1999.

                                      29

<PAGE>

  . For corporate systems, we are a young company with new technology and no
    legacy applications. All of our hardware is less than two years old and
    is still supported by vendors and suppliers. Corporate software consists
    mainly of desktop applications, the financial system and the payroll
    system--preparing these applications to be Year 2000 ready consists of
    applying patches and installing software upgrades. We are in the process
    of installing Microsoft SMS, which will enable our organization to
    inventory every desktop and server to determine the extent of those
    items' Year 2000 readiness. Estimated time of completion for this project
    is July 1999. We believe that in the majority of cases, we will be
    applying software upgrades or patches to correct potential issues that
    could result from the Year 2000 issue. Remediation of non-ready systems
    is expected to be completed during the third quarter of 1999.

  . We have performed an internal risk assessment to identify mechanical and
    building systems that could be at risk for Year 2000-related issues. As
    part of the Year 2000 readiness effort, we have identified non-computer
    technology and outside suppliers that may be susceptible to Year 2000
    issues, including our local electricity supplier and our security access
    system provider. Completion of assessment and testing of mechanical and
    building systems is expected to be completed during the third quarter of
    1999.

   We have performed research on the Year 2000 readiness of each of our major
suppliers, including Sterling Software, en.able, PGI Companies, Midwest
Graphics, ICT Group, Transcom USA and our wholesale electricity suppliers,
Dynegy, Conectiv, Allegheny Energy, DTE Co-Energy and PacifiCorp. We have
relied on Internet postings, SEC filings, Year 2000 readiness disclosure and
documentation provided by suppliers and partners. The research has obtained
standard responses on Year 2000 readiness, specifically that each company is
either Year 2000 ready or in the process of becoming Year 2000 ready. For those
business systems that we deem critical to our operations and business
sustainability, we will require a more detailed response. We are in the process
of preparing material to be sent to these suppliers and vendors and expect that
letters will be sent by the end of the second quarter of 1999, requesting
responses to be received in the following quarter. These letters are being
prepared and sent in tandem with our system wide test to ensure that these
suppliers and vendors are in fact Year 2000 ready. We expect to complete this
process during the third quarter of 1999. However, we cannot assure you that
the failure of one of these third parties to be Year 2000 ready will not have a
material adverse effect on us. If we determine no later than September 1999
that an information technology service provider, outsourcing provider or
supplier will not be Year 2000 ready, we believe we will be able to select in a
timely manner alternatives which are Year 2000 ready.

  Costs To Address Year 2000 Issues

   In order to meet current and future business needs, we are assessing our
hardware and software applications and making them Year 2000 ready. We are also
utilizing the services of Sterling Software to assist with the integration
testing of data shared with our information technology service providers,
outsourcing providers and suppliers. We have expensed less than $0.1 million in
connection with our Year 2000 readiness efforts since inception through
March 31, 1999 and we expect to incur approximately $0.4 million during the
remainder of 1999. These costs represent work to be performed to both make our
corporate and business systems Year 2000 ready and to assess the Year 2000
readiness of our information technology service providers, outsourcing partners
and suppliers.

  Risks Associated With Year 2000 Issues

   We are subject to external Year 2000-related failures or disruptions that
might generally affect industry and commerce, such as failures by energy
generation or utility distribution companies and related service interruptions.
These failures or disruptions are especially critical to us as a seller of
retail electricity products. Notwithstanding our Year 2000 efforts, the failure
of our systems or those of any of our information technology service providers,
outsourcing partners or suppliers, or the failure of the Internet generally, to
be Year 2000 ready could harm the operation of our systems or have unforeseen,
material adverse consequences to us. These consequences could include the
inability to bill our customers. All of these factors could materially
adversely affect our business, results of operations and financial condition.

                                       30

                                                                  Choose wisely.
<PAGE>

  Contingency Plans

   We have no formal overall worst-case scenario because we divide up our Year
2000 risk into internal and external systems. An overall worst-case would be if
the highest risk areas of the internal and external were to occur
simultaneously. The internal corresponds to business sustainability and the
external deals with servicing our customers; accordingly, these two areas have
different priorities and different exposure to risks. We expect that at the
corporate level we would sustain no adverse effects due to the short-term loss
of corporate information technology systems. For our business systems, a long-
term disruption could impact our ability to serve customers, including customer
billing, customer service and our ability to interact with electric utility and
distribution companies. This would not, however, impact the ability for
customers to receive our energy products or electric distribution and
generation in general. As part of our contingency planning, which we expect to
complete no later than the beginning of the fourth quarter of 1999, we will use
risk assessment to develop contingency plans for worst-case scenarios in each
area of our business.

Recent Accounting Pronouncements

   The Financial Accounting Standard Board (FASB) recently issued SFAS No. 130,
Reporting Comprehensive Income. SFAS No. 130 establishes standards for
reporting and displaying comprehensive income and its components in financial
statements. Comprehensive income, as defined, includes all changes to equity
(net assets) during a period from non-owner sources. SFAS No. 130 is effective
for financial statements for fiscal years beginning after December 15, 1997. We
have not had any transactions that are required to be reported in comprehensive
income.

   The FASB recently issued SFAS No. 131, Disclosure about Segments of an
Enterprise and Related Information. SFAS No. 131 establishes standards for the
way public business enterprises are to report information about operating
segments in annual financial statements and requires those enterprises to
report selected information about operating segments in interim financial
reports. SFAS No. 131 is effective for financial statements for fiscal years
beginning after December 15, 1997. We do not believe we currently operate in
more than one segment.

   The FASB, in June 1998, issued SFAS No. 133, Accounting for Derivative
Instruments and Hedging Activities. SFAS No. 133 establishes accounting and
reporting standards requiring that every derivative instrument, including
derivative instruments embedded in other contracts, be recorded in the balance
sheet as either an asset or liability measured at its fair value. SFAS No. 133
requires that changes in the derivative's fair value be recognized currently in
earnings unless specific hedge accounting criteria are met. Special accounting
for qualifying hedges allows a derivative's gains and losses to offset related
results on the hedged item in the income statement, and requires that a company
must formally document, designate and assess the effectiveness of transactions
that receive hedge accounting. SFAS No. 133 is effective for fiscal years
beginning after June 15, 1999. A company may also implement SFAS No. 133 as of
the beginning of any fiscal quarter after June 16, 1998. SFAS No. 133 cannot be
applied retroactively. SFAS No. 133 must be applied to derivative instruments
and derivative instruments embedded in hybrid contracts that were issued,
acquired or substantively modified after December 31, 1997 (and, at the
company's election, before January 1, 1998). We do not have any derivative
instruments at this time; however, such instruments may be embedded in future
electricity contracts.

   The American Institute of Certified Public Accountants Statement of Position
(SOP) No. 98-1, Software for Internal Use, provides guidance on accounting for
the cost of computer software developed or obtained for internal use. SOP No.
98-1 is effective for financial statements for fiscal years beginning after
December 15, 1998. We do not expect that SOP No. 98-1 will have a material
impact on our financial statements. GreenMountain.com anticipates that in the
second quarter of 1999 it will begin capitalizing certain costs in accordance
with SOP No. 98-1 associated with projects that enter the development stage,
including its Web site development project.

Our Mission

   GreenMountain.com uses the Internet and other media to offer environmentally
friendly electricity and other products to consumers. Our Web site--
www.greenmountain.com--will use the rich interactive resources of the Internet
to educate consumers about the environmental impact of their everyday purchases
and to make it easy and appealing for them to use those purchases as agents of
change for a cleaner and healthier environment. Our mission is to make Green
Mountain the leading brand for environmentally friendly products.

   Based on number of customers served, we are the leading retailer of green
electricity to residential customers in Pennsylvania and California -- the two
states that have effectively opened their residential electricity markets to
competition. We intend to offer green electricity products in each deregulated
utility market in which we can compete effectively. We also offer solar
generation equipment.

   We have very recently expanded our product offerings to include a Green
Mountain co-branded Visa card, ecological tours and vacations, electric
bicycles and environment-related books, and we expect to continue to expand our
selection of green consumer products.


The Opportunity

  Public Concern About Environmental Problems Is High

   Our environment faces serious problems.

  .Air pollutants released by the burning of fossil fuels pose serious
   threats to human health, ecosystems, visibility, crops and buildings.

  .113 million Americans live in approximately 130 localities that fail air
   quality standards.

  .Smog (ground level ozone) contributes to respiratory ailments.

  .Emissions of nitrogen oxide are a major contributor to formation of smog.

  .Electric utility generation accounts for 30% of nitrogen oxide emissions
   in the United States.

  .The mixture of sulfur dioxide and nitrogen oxide causes acid rain,
   resulting in the acidification of lakes and streams, damage to trees at
   high elevations and accelerated decay of buildings and paints.

  .Electric utility generation accounts for 66% of sulfur dioxide emissions
   in the United States.

  .1998 was the hottest year on record and this decade has been the hottest
   decade on record.

  .Scientists generally believe that increases in carbon dioxide emissions
   contribute to global warming.

  .Electric utility generation accounts for 36% of carbon dioxide emissions
   in the United States.

A recent Worldwatch publication stated:

    . . . [There] is an exciting alternative economic model that
    promises a better life everywhere without destroying the earth's
    natural support systems. The new economy will be powered not by
    fossil fuels, but by various sources of solar energy and hydrogen
    . . . Instead of a throwaway economy, we will have a
    reuse/recycle economy.

Even large oil companies seem to recognize the need for cleaner burning fuels
and renewable energy sources and are actively exploring alternatives to fossil
fuels. According to Worldwatch Institute:

  .Atlantic Richfield's chief executive officer sees his company's large
   holdings of natural gas playing a key role in the transition from a
   carbon-based energy economy to one based on hydrogen.

  .Royal Dutch Shell has announced a commitment of $500 million to renewable
   energy sources.

According to Environmental Data Services, British Petroleum has announced plans
to expand its subsidiary BP Solar ten-fold over the next decade to achieve
annual sales of solar photovoltaic cells of $1 billion.

We are convinced of the need to switch from the current fossil-fuel-based,
throwaway economy to an environmentally sustainable economy, and we believe
that our g*commerce model can help accelerate this change.

   We believe that Americans are more concerned than ever about environmental
problems and are more knowledgeable than ever about green products and
processes. We also believe that Americans are increasingly sensitive to the
effect that their individual behavior can have on the environment and are
willing to change that behavior in order to protect the environment. We believe
that this behavioral trend is evidenced by the recent growth of recycling.
According to BioCycle Magazine, the percentage of recycled waste grew from 8%
in 1990 to 28% in 1997.



                  [BAR CHART REPRESENTING PERCENTAGE INCREASE
                      IN WASTE RECYCLED FROM 1990 TO 1997]

In addition, BioCyle Magazine reported in April 1998 that the number of
community curbside recycling programs had increased from 1,042 in 1989 to 8,937
in 1997.

   According to the 1998 Green Gauge Report by Roper Starch Worldwide, 47% of
Americans "cite difficulty in finding pro-environmental versions of products
they need and say not having time to shop around to find them is a "major
reason' or "something of a reason' for not doing more environmentally." We
believe that if offered a convenient, cost-effective choice, many consumers
will purchase a product that is green over one that is not. Jacquelyn Ottman,
the author of Green Marketing: Opportunity for Innovation, has said "[p]eople
are "greener' today than ever before" and "[g]reen marketing is looking more
mainstream all the time." The 1998 Green Gauge Report states:

    As Americans' levels of environmental concern are high and
    sizable numbers of Americans say they would feel more favorable
    toward a business that takes environmental action, marketing
    around environmental issues is an excellent way to reach
    consumers and build a "power brand."

We aim to make Green Mountain a leading brand for green products.

  Deregulation Is Empowering Consumers To Change The Way Electricity Is Made

   Deregulation of the $200 billion electric utility industry--the largest
industrial source of air pollution in the United States--is part of a global
trend away from government control and toward free markets. The electricity
industry includes three basic functions: the production or generation of
electricity, wholesale and retail marketing of electricity and transmission and
distribution of electricity to the end user. Historically, in the United States
regulated electric utilities have provided bundled electricity service,
including generation,

                                       33

It's a small planet.(SM)
<PAGE>

marketing and distribution, within exclusive franchise service territories. The
underlying premise of the regulatory system guaranteed the utilities freedom
from competition and a "reasonable" rate of return on their investment in
exchange for a limitation on that investment return in the form of government
regulation of the prices the utilities were allowed to charge their customers.

   The wholesale power sector is largely subject to federal regulation, while
the retail operations of electric utilities are principally regulated at the
state level. Since the passage of federal legislation in 1992, the Federal
Energy Regulatory Commission has implemented measures to facilitate competition
in wholesale power marketing. On a state-by-state basis, states have begun to
introduce competition to the retail power marketing and generation sectors.
Because of the inherent inefficiencies that would be involved in the
duplication of the "poles and wires" and other facilities required for the
distribution of electricity, this function remains in the hands of state-
franchised monopolies, subject to traditional rate of return price regulation.
As a result of deregulation, the power generation and marketing sectors have
been separated from the distribution function. Thus, the electric utility
industry is changing from one characterized by a single provider of bundled
electricity service to one having a number of electricity generators and
marketers who are not subject to governmental price regulation, but are subject
to market price competition and risk.

   Currently, the industry segment in which we compete is retail marketing and
our primary target customers are residential customers. Deregulation is
providing consumers with a choice of electricity supplier and of generation
source. Because all electricity delivered into the electric distribution system
serving an area is fungible, choice does not affect the actual electrons
delivered for the consumer's use. It does, however, influence the source of the
electricity delivered to the distribution system. Choice allows the growing
community of informed and environmentally conscious consumers a convenient way
to direct market forces toward positive environmental change.

   Because deregulation is a political process, the timing and outcome of
deregulation in any particular state is unpredictable. The specific features of
the deregulation program implemented in a particular state affect whether and
to what extent free competition will develop in that market. To date, four
states--Pennsylvania, California, Massachusetts and Rhode Island--have opened
their retail electricity markets to competition with varying degrees of
success.

  .Pennsylvania. Pennsylvania's deregulation program has been the most
   successful, resulting in the most active electricity retail market in the
   United States. Pennsylvania consumers considering selection of a power
   marketer other than their traditional electric utility compare their
   "shopping credit" to the rate offered by that marketer. The "shopping
   credit" is an amount deducted from the bill that the consumer would
   receive from the utility if the consumer selects another supplier. The
   prices charged for electricity by the suppliers are not subject to
   Pennsylvania price regulation. Unregulated suppliers, including
   unregulated affiliates of the traditional utilities, have been able to
   offer power to consumers at prices equal to or less than the Pennsylvania
   shopping credit, thus providing an incentive for consumers to switch from
   their traditional utility supplier. We have not used discounts or price
   incentives in establishing our rates, which are based on wholesale market
   prices and competitive retail margins. From time to time, we do offer
   sign-up incentives, such as an initial month of free service. The cost of
   these incentives has been included in customer acquisition costs and has
   not had a significant effect on our results of operations. See
   "Management's Discussion and Analysis of Financial Condition and Results
   of Operations." While we do not view ourselves as a price competitor, we
   believe that we benefit from price competition because it contributes to
   an active market of consumers who have made a deliberate choice of
   electricity supplier.

   Pennsylvania's retail electricity market opened for competition on January
   1, 1999. As of March 31, 1999, approximately 7% of the households in the
   Pennsylvania market had elected to switch from their incumbent electricity
   provider. Of those households, we estimate slightly less than one-third
   switched to a green electricity product. As of March 31, 1999, there were
   seven significant residential electricity suppliers (excluding incumbent
   electric utilities and their affiliates) competing in the residential
   Pennsylvania market, and two of them offered green electricity products.

                                       34

                                                                  Choose wisely.
<PAGE>

  .California. California's deregulation program is currently in a
   transitional phase that is substantially less favorable to free market
   competition than the Pennsylvania program. Under the California program,
   consumers considering selection of an unregulated supplier are allowed a
   shopping credit equal to the average wholesale cost of power available
   under a pool known as the California Power Exchange. Because the shopping
   credit is equal only to the wholesale value of the electricity consumed,
   independent suppliers cannot generally offer consumers a price savings
   compared to the traditional utilities. A limited exception exists as a
   result of credits available for the production of electricity from
   renewable resources. The absence of legitimate price competition has
   limited the development of a vibrant, deregulated market in California.

   California's retail electricity market opened for competition on April 1,
   1998. As of March 31, 1999, 1% of the households in California had chosen
   to switch from their incumbent electricity provider. As of March 31, 1999,
   there were five residential electricity suppliers (excluding incumbent
   electric utilities and their affiliates) competing for new customers in
   the California market, and all of them offered green electricity products.
   As a result, all households that have switched are receiving green
   electricity.

  .Massachusetts. Although the Massachusetts retail electricity market
   nominally opened for competition on March 1, 1998, to date the shopping
   credit in Massachusetts has not achieved a level permitting competitive
   retail suppliers to match the rates offered by incumbent electricity
   providers. Accordingly, no significant competition for residential
   customers has developed. Under the Massachusetts deregulation program, the
   shopping credit increases over time.

  .Rhode Island. Although Rhode Island's residential retail electricity
   market was formally open for competition by July 1998, no significant
   competition has developed in Rhode Island for the same reason competition
   for residential customers has not developed in Massachusetts. Under the
   Rhode Island deregulation program, the shopping credit increases over
   time.

   The primary reason for the success of the Pennsylvania deregulation program
as compared to the programs in California, Massachusetts and Rhode Island is
that Pennsylvania's program has stimulated customer interest by allowing
competitive retail suppliers to offer consumers savings. Although the political
nature of the deregulation process makes it impossible to provide any assurance
in this regard, we believe that the legislators and regulators in states
opening their electric utility markets for competition in the future will
consider the success of the Pennsylvania deregulation program when establishing
the specific features of the deregulation program to be implemented in their
respective states. As the only independent power marketer focusing on
residential customers and operating in both the Pennsylvania and California
markets, we believe that we have established a credibility that will allow us
to effectively advocate the Pennsylvania model in consultation with government
officials in states exploring electric utility deregulation. See "Risk
Factors--Risks Related to Establishment of our Business--Our Ability to Expand
our Existing Green Electricity Business into New Markets Depends on the Outcome
of the Deregulation Process in Each State."

   Pennsylvania, California, Massachusetts and Rhode Island are currently the
only states that have implemented competition on a statewide basis. In addition
to these four states, Arizona, Arkansas, Connecticut, Delaware, Illinois,
Maine, Maryland, Michigan, Montana, Nevada, New Hampshire, New Jersey, New
Mexico, New York, Oklahoma, Virginia and, most recently, Texas have taken
formal action to deregulate. We expect that more than half of the states will
provide consumers a choice of electricity supplier and generation source by the
end of 2003.

   The deregulation of electricity follows the precedent of deregulation of
long distance telephone services, with some important differences. While long
distance telephone service (like wholesale electric sales) is largely governed
by federal laws, electric utilities are principally regulated by the states.
Also, we will be able to differentiate our products by their generation source
whereas the long distance telephone market is marked by an absence of product
differentiation.

  The Internet And Online Commerce Are Growing

   We believe that the Internet is emerging as one of the most significant
global communications media. It is enabling millions of people to share
information and conduct business electronically. A number of factors are
contributing to the dramatic growth of this new medium, including:

  .Ease of use;

  .Reduced costs;

  .Faster access;

  .Improved content; and

  .Increased attention in other media.

Jupiter Communications estimates that the number of Internet users in the world
will grow from 112 million in 1998 to 244 million in 2002.

   Online retailers are able to communicate effectively with customers by
providing:

  .Visual product presentations;

  .Up-to-date pricing and product information;

  .Customer support and opportunities for customer feedback;

  .Product offerings tailored to customer preferences; and

  .Electronic billing and payment systems.

These features, together with the widespread availability of express delivery
services, make online retailing a viable alternative to traditional stores.
Online retailers also avoid the burden of managing and maintaining numerous
local facilities and enjoy lower transaction costs.

   An increasingly broad base of products and services are being sold online,
including books, brokerage services, computers, music and travel services.
Jupiter Communications estimates that the value of goods and travel services
purchased on the Internet in the United States alone will grow from $7.1
billion in 1998 to $41.1 billion in 2002. We cannot assure you that our sales
will have a comparable growth rate. Our growth rate will be affected by a
number of factors, including:

  . Our ability to position the Green Mountain brand name;

  . Our ability to broaden our product offerings;

  . The timing of deregulation in the states that have not yet opened their
    residential electricity markets to competition;

  . The competition for customers interested in purchasing green consumer
    products; and

  . The continued development of public concern about environmental issues.

See "Risk Factors." To date, approximately 4% of customer sign-ups for our
green electricity have come through our Web site. We have only very recently
begun to offer other green consumer products over the Internet.

   As the number of online content, commerce and service providers has
expanded, strong brand recognition and strategic alliances have become critical
to success. Brand development is especially important for online retailers due
to the need to establish trust and loyalty with customers in the absence of
face-to-face interaction.

The Green Mountain Advantage

   We believe that a significant opportunity exists for a company to market
green consumer products over the Internet. Research performed for us by
Copernicus, The Marketing Investment Strategy Group, which has assisted us with
the development of our overall marketing strategy, indicates that our green
electricity customers in Pennsylvania are 31% more likely to have accessed the
Internet in the last three months than the general population. According to the
1998 Green Gauge Report, an annual environmental survey conducted by Roper
Starch Worldwide, "the Internet is one source by which Americans are gaining
information about the environment" and "[i]ndeed, 71% of [households with one
or more personal computers] say they know "a lot' or "a fair' amount about the
environment." We believe that by creating an Internet destination site that
will appeal to people who care about the environment, we can make Green
Mountain a leading brand for green products.
   We believe that we are uniquely qualified to capitalize on the opportunity
to market green products over the Internet as a result of:

  .Our success in marketing green electricity to residential customers in the
   deregulated utility markets of Pennsylvania and California; and

  .The growing awareness of our Green Mountain brand name.

   Based on number of customers served, we are currently the leading seller of
green electricity to residential customers in Pennsylvania and California --
 the two states that have effectively opened their residential electricity
markets to competition. In June 1998, we began marketing electricity products
in Pennsylvania, which opened for competition on January 1, 1999. As of March
31, 1999, we were serving approximately 48,100 customers in Pennsylvania. The
Xenergy 1999 Retail Wheeling Multi-Client Study Phase 4 Final Report states:

     The survey analysis identified Green Mountain as "the" green
     marketer in Pennsylvania, with a total market share of 29
     percent of all switchers, and with nearly all of the green
     market share. Much of their success may be attributable to
     their ability to effectively market, as their prices are often
     higher than those of other green marketers in Pennsylvania.
     They are the most recognized supplier in the market, whether
     or not the customers are green purchasers.

California's retail electricity market opened for competition on April 1, 1998.
Our marketing strategy in California was to concentrate first on northern
California due to its higher concentration of environmentally sensitive
consumers. We have recently increased our efforts in southern California. As of
March 31, 1999, we were serving approximately 19,900 customers in California,
approximately 75% of which were in northern California.

                                       38

                                                                  Choose wisely.
<PAGE>


   The following table illustrates the number of our customers as of the end of
each calendar quarter commencing on or after April 1, 1998.

[BAR CHART REPRESENTING INCREASE IN QUARTERLY CUSTOMER GROWTH FROM 2ND QTR 1998
           TO 1ST QTR 1999 IN TERMS OF CUSTOMERS SERVED APPEARS HERE]

Quarter to quarter comparisons of the number of customers is not necessarily
meaningful and should not be relied on as an indication of future growth in the
number of customers. Growth in the number of our customers is expected to be
affected significantly by the timing of our entry into new deregulated markets.
We are likely to experience higher customer acquisition rates during the
initial market opening period.

   Market research performed for us by Copernicus indicates that from its first
introduction to the Pennsylvania market in June 1998, awareness of the Green
Mountain brand grew to 55% of residential households by April 1999. Similar
market research performed for us by Copernicus indicates that in November 1998,
16% of residential households in northern California and 11% of residential
households in the entire state were aware of our Green Mountain brand. By April
1999, awareness of the brand had grown to 31% in northern California and 24%
statewide. See "--Marketing, Sales and Customer Service--Marketing."

Our Strategy

  Position "Green Mountain" As The Most Trusted And Best Known Green Brand

   We are the first and only company to offer green electricity products
primarily to residential customers in the deregulated electric utility markets
of both California and Pennsylvania and one of the first companies to offer
green electricity products over the Internet. We intend to take advantage of
this first mover momentum to offer a wide variety of green products over the
Internet and position Green Mountain as the most trusted and best known
environmental brand. We are engaged in aggressive marketing aimed at increasing
awareness both of the environmental impacts of people's everyday purchases and
of the Green Mountain brand through traditional media, principally in states in
which we offer our energy products. We will continue to expand our marketing
effort, especially on the Internet, as we identify new green products that can
be marketed beyond those states.

   We seek to establish relationships with environmental groups in support of
our message that personal purchasing decisions can effect positive
environmental change.

   Some of our green electricity products are identified as environmentally
preferred by:

    .Natural Resources Defense Council

    .Environmental Defense Fund

    .Clean Air Council (of Pennsylvania)

In addition, the Union of Concerned Scientists has chosen one of our products
to serve its California office and the electric vehicle charging station in its
parking lot.

                                       39

It's a small planet.(SM)
<PAGE>

   We have an affinity marketing program with each of the following
organizations:

  .Redwood Alliance, Arcata, California

  .Bay Keeper, San Francisco, California

  .Save Our Shores, Santa Cruz, California

  .AIDS Fund, Philadelphia, Pennsylvania

   Each of the following organizations has supported our work in community
outreach programs:

  .Coalition of Clean Air, Los Angeles, California

  .The Nature Company, Berkeley, California

   The Episcopal Diocese of California under its Episcopal Power & Light
Program has recommended Green Mountain as the preferred electricity provider in
California. Several Episcopal churches have chosen our products to serve their
church facilities.

   We stake our reputation on the environmental soundness of our products. We
participate in the nation's first voluntary certification program for
environmentally preferred electricity products--the Green-e Renewable
Electricity Branding Program. Two of our three green electricity products
offered to customers in Pennsylvania and both of our green electricity products
currently being offered to new customers in California are Green-e certified.
The Green-e program is intended to ensure that retail suppliers of Green-e
certified electricity actually buy the renewable energy promised to their
customers and to help consumers compare different electricity offerings. Under
the program, annual independent audits of the delivery of certified products
are conducted. Green-e is administered by the Center for Resource Solutions, a
non-profit organization based in San Francisco, with an independent board of
environmentalists, consumer advocates and renewable energy experts. In order
for an electricity product to be certified by Green-e, it currently must
satisfy the following criteria:

  . At least 50% of the product must come from specified renewable sources;

  . Emissions of sulfur dioxide, nitrogen oxide and carbon dioxide from the
    non-renewable generation component of the product must not exceed average
    emissions rates of fossil fuel power that is otherwise available in the
    electricity distribution system and the total fossil fuel emissions of
    the product must not exceed the average emissions rate of power that is
    otherwise available in the electricity distribution system;

  . None of the product may come from nuclear power, other than a proportion
    that is no greater than the proportion of nuclear power that is otherwise
    available in the electricity distribution system; and

  . The product must be offered by a company committed to following the
    Green-e Code of Conduct on ethical treatment of customers, including
    using simple contracts and disclosure labels.

  Offer Convenience And Selection

   In order to make it convenient for consumers to find pro-environmental
versions of products they need, we are expanding the offerings on our Web site
to include a broad selection of green consumer products in addition to the
green electricity products and solar generation equipment that we currently
offer in Pennsylvania and California. We will offer products obtained through
contracts with suppliers under our Green Mountain brand name, but do not intend
to do any manufacturing. We intend to pursue relationships with others to make
their green products available on our Web site, and we expect to derive
revenues from any sales of these products made through our site.

  Develop And Maintain Our Web Site As A State-of-the-Art, Interactive Online
Commerce Platform

   We are upgrading our Web site and technology systems to create a state-of-
the-art, interactive commerce platform that will enhance our expanded product
offerings and take advantage of the unique characteristics of online retailing.
Among other technology objectives, we intend for our Web site to:

  .Provide personalized service programs;

  .Make the user interface as intuitive, engaging and expedient as possible;
   and

  .Provide efficient fulfillment of product orders.

                                       40

                                                                  Choose wisely.
<PAGE>

   We currently use traditional media both to sell our products and to
encourage people to visit our Web site. As the Green Mountain brand becomes
more recognizable, we expect that the majority of our sales transactions will
be made through our Web site.

  Develop And Maintain An Online Community That Fosters And Supports
"g*commerce"

   We are seeking to develop an online community of individuals who are
concerned about the environment and want to use their personal purchase
decisions to effect positive environmental change. We believe that these
individuals will purchase a green product if:

  .It is convenient;

  .It is equal or better in quality;

  .It has no more than a relatively minimal incremental cost; and

  .They perceive that their purchase of that product will have a positive
   effect on the environment.

   We refer to the concept of harnessing free market forces to effect positive
environmental change as "g*commerce." We believe that educating consumers about
their own ability to effect positive environmental change through prudent
purchases will result in both revenue opportunities for us and improvements to
the environment.

   Further, we believe that creating a large community of consumers of green
products will permit us to utilize the collective buying power of these
individual consumers to obtain and, in turn, offer green products at lower
prices than might otherwise be available and that, as we are able to lower
prices in this manner, we will attract additional customers.

   Our approach to community development also includes affinity programs
intended to retain existing customers, increase revenue opportunities and
attract new customers.

Marketing, Sales And Customer Service

  Outside Service Providers

   We use third-party service providers to perform a number of key functions in
the operation of our business that would otherwise be performed by our
employees. We refer to our use of third-party service providers to perform
these functions as "outsourcing" and refer to these service providers as our
"outsourcing partners." Our extensive use of outsourcing reduces our internal
human resource and office space requirements and enables our management to
focus on our overall marketing strategy and the identification of new product
opportunities. See "Risk Factors--Other Risks Related to our Business
Generally--Poor Performance by One or More of our Outside Service Providers
Could be Disruptive to our Business Operations."

   Key functions that we outsource and the outside service providers currently
performing those functions for us are identified below.

  Marketing

   Mass Media. To date, our brand awareness efforts have been focused on
Pennsylvania and California and have utilized primarily television, print,
radio and billboard advertisements.

   The Internet. We have engaged in extensive Internet banner advertising in
Pennsylvania and California. We intend increasingly to use the Internet in our
brand awareness efforts. We are pursuing marketing relationships with Internet
portals and other high-traffic Web sites in order to increase the level of
traffic to our

                                       41

It's a small planet.(SM)
<PAGE>

Web site. These arrangements typically involve banner advertising containing
our message and an interactive link to our Web site, but can also involve other
products such as e-mail.

   Direct Mail. We employ a highly targeted, database-driven direct mail
marketing strategy, in which direct mail is followed by outbound telemarketing.
We use two main categories of lists to target potential customers--membership
lists for environmental organizations and demographically-profiled lists
obtained from national databases. We outsource the list processing and analysis
function to Experian Database Marketing Solutions and the mailing function to
PGI Companies.

   Affinity Programs. We use affinity marketing programs to market our products
through groups that share our interest in the environment. We have entered into
agreements with approximately 40 groups for the promotion of our electricity
products. Under these agreements, which have terms that range from three months
to more than a year, we pay the affinity partner a fee for each electricity
customer referred by the partner. These affinity partners promote our
electricity products through bill inserts, telemarketing, in-store activities
and other means. See "--Our Strategy--Position "Green Mountain" as the Most
Trusted and Best Known Green Brand."

   Events and Promotions. We utilize special events and promotions such as:

  .Sponsorship of festivals and concerts by our spokesperson, Kenny Loggins;

  .Appearances by GreenMountain.com representatives at local environmental,
   health and sporting events to distribute information about us and our
   products;

  .Sponsorship of a tour through California by the "Veggie Van," an
   alternative fuel vehicle that provides information about renewable energy;
   and

  .Appearances of our hot air balloon.

   Marketing Relationships. Our overall marketing strategy has been developed
with the assistance of Copernicus, The Marketing Investment Strategy Group,
with which we have an ongoing relationship. In March 1995, Green Mountain Power
Corporation entered into a consulting agreement with Copernicus, which was
amended in March 1997. The agreement, which was assigned to us by a subsidiary
of Green Mountain Power Corporation, continues in effect for a series of
consecutive one-month terms until terminated by either party upon 90 days'
prior written notice. Under the agreement, we are required to pay a monthly
retainer fee of $20,000. The agreement provides for the placement of separate
purchase orders that are governed by the agreement. Total payments under this
agreement for 1998 were approximately $491,491 and for the three months ended
March 31, 1999 were $170,254. Other clients of Copernicus include such well-
known companies as AT&T, Compaq Computer, Hewlett-Packard, Michelin, Miller
Brewing, Mobil, Nasdaq, Pepsi-Cola, Polaroid and Visa.

   We have established a relationship with The Cullinan Group, an integrated
marketing communications agency, to assist us with our brand development. More
specifically, on January 1, 1998, we entered into a marketing services
agreement with The Cullinan Group to prepare and execute marketing
communications plans and projects and place advertising for our energy
business. The agreement will continue until terminated by either party upon 90
days' prior written notice. Under the agreement, we are required to pay a
minimum monthly retainer fee of $30,000, which is credited against charges
incurred by The Cullinan Group on our behalf. Under the agreement, prior to the
commencement of each calendar quarter, we and The Cullinan Group agree upon a
budget for monthly expenses during the quarter and we then make monthly advance
payments in the amount of anticipated expenses for the month as reflected in
the agreed budget, less the monthly retainer fee. Following each month, The
Cullinan Group invoices us for actual expenses in excess of the advance
payments. The Cullinan Group may not exceed budgeted amounts by more than 10%
without our prior written approval. Total payments under this agreement for
1998 were approximately $16,228,000 and for the three months ended March 31,
1999 were $6,511,613. Other clients of The Cullinan Group include Georgia
Pacific and Thinsulate Insulation/3M.

<PAGE>


   In addition, we have established a relationship with Strategic Interactive
Group, an interactive media consulting agency and specialized Web site
developer, to assist us with enhancements to our Web site and our use of the
Internet in our brand awareness efforts. Our agreement with Strategic
Interactive Group may be terminated by either party by giving the other party
at least 90 days prior written notice. In addition, if Strategic Interactive
Group breaches its obligations or engages in action or inaction that
significantly endangers timely completion of its obligations and the breach,
action or inaction continues for more than 30 days after notice by us, we may
terminate the agreement at any time thereafter. If Strategic Interactive Group
is not in default and we fail to make any payment when due and that failure
continues for more than 30 days after notice by Strategic Interactive Group,
then Strategic Interactive Group may terminate the agreement. The agreement
contemplates that we will prepare and submit specific, authorizing
documentation for the procurement of specific services under the agreement.
This documentation when agreed to by us and Strategic Interactive Group
establishes the estimated budget for the specific services to be provided.
Under the agreement, we pay for services based on actual hours worked, but not
more than the agreed budget estimate without our prior approval. We also
reimburse Strategic Interactive Group for expenses incurred by it in
performance of its services to us. Total payments under this agreement for 1998
were approximately $1,191,257 and for the three months ended March 31, 1999
were $435,070. Other clients of Strategic Interactive Group include Dell
Computer, Federal Express, Kraft Foods, L.L. Bean and American Express.

  Sales

   Customers may purchase our products through the following three methods:

  .Internet. Customers may purchase our products through our Web site.

  .Telephone. Customers may purchase our products through inbound or outbound
   telephone contact. We outsource call center functions to ICT Group. On
   January 30, 1998, we entered into a contract with ICT Group to manage our
   call center and resulting databases. This agreement continues until either
   party terminates it by providing the other party with 30 business days'
   prior written notice. Under this agreement, we pay fixed monthly fees of
   approximately $8,700, as well as actual costs associated with service
   representatives' time and communication costs incurred resulting from
   inbound and outbound calls. We have also begun to outsource call center
   functions to Transcom USA.

  .Mail. Customers may purchase our products by mail. We outsource our mail
   response processing to Midwest Graphics.

   When a customer purchases our products through one of these three methods,
information about the customer is placed into our Information Network and an
electronic data package is sent to a transaction router system. The transaction
router automatically submits an order for the appropriate customer service
activity. Our Information Network is managed by Sterling Software, and the
transaction router is managed by en.able, L.L.C. See "Information Technology"
and "Related Party Transactions--Other Transactions and Relationships."

  Customer Service

   Orders submitted through our Information Network initiate customer service
functions. These functions include primarily:

  .Customer Fulfillment. This function fulfills customer requests for
   additional information about us and our products. We outsource this
   function to PGI Companies.

  .Product Delivery. Product delivery is effected directly by our suppliers.

  .Billing and Customer Care. We outsource billing and customer care
   functions to en.able, L.L.C. We have entered into an agreement with
   en.able which provides that it will provide billing and the related
   customer care to our residential customers and will develop and implement
   a system to facilitate our electronic interface with electric utility
   distribution centers. Unless earlier terminated, the initial term of the
   agreement ends on November 1, 2002, but the agreement may be renewed prior
   to the end of the initial term and each renewal term for an additional
   one-year period by mutual agreement of the parties.

                                       43

<PAGE>


   Beginning January 1, 2000, during the initial term either party may
   terminate the agreement upon 270 days' prior written notice to the other
   party. Following the initial term, the parties may terminate the agreement
   on 180 days' notice. In addition, either party may terminate the agreement
   if the other party breaches a material provision of the agreement and that
   breach is not cured within 30 days after notice is given to the breaching
   party by the non-breaching party. We have agreed to pay en.able monthly
   service charges for call center and billing services, additional resource
   charges and cost of living adjustments. The monthly charges are variable
   and are based on the number of billable accounts maintained each month;
   however, we have agreed to pay minimum monthly service charges for call
   center service and billing services, currently $112,500 per month.

Our Green Electricity Products

   Deregulation of the electric utility industry is providing environmentally
conscious consumers with a choice of electricity supplier and generation
source. We are currently offering green electricity products--electricity
produced from renewable and other environmentally preferable generation
sources--in Pennsylvania and California. To date, more than 99% of our revenues
have come from the sale of our green electricity products in Pennsylvania and
California.

[PRINT ADVERTISEMENT--"IF YOU'RE PLANNING TO RECYCLE" --APPEARS HERE.]
   We offer three green electricity products to residential electricity
customers in Pennsylvania. The following table indicates, for each of these
products, its generation composition and the average monthly additional cost or
savings of the product as compared to the price of non-green electricity
offered by incumbent electricity providers, weighted across all utility service
territories based on our actual sales.

   There may be a construction-related delay for up to 12 months from the time
a customer orders the Wind for the Future 2.0SM product until the commencement
of wind-powered generation. During this delay, the customer will receive
electricity from renewable generation sources. Wind for the Future 2.0SM
customers pay the rate for the Wind for the Future 2.0SM product during the
delay period and would receive a refund of the difference between that price
and the price of the product actually delivered if the wind turbine does not
commence operations within 12 months.

   Our current California electricity products were only recently introduced.
The products we previously offered in California--Water Power, 75% Renewable
Power and Wind for the FutureSM--remain available only to customers who
purchased them prior to the introduction of our current products. These
products were priced higher than our current 100% Renewable Power 2.0SM
product, which resulted in an average monthly additional cost to the consumer
of $5.17 for Water Power, $6.36 for 75% Renewable Power and $11.13 for Wind for
the FutureSM.

   We expect to offer green electricity products similar to those offered in
Pennsylvania and California in the retail electricity market of any state that
deregulates in a manner that we believe will allow us to compete effectively.
See "Risk Factors--Risks Related to Establishment of our Business--Our Ability
to Expand our Existing Green Electricity Business into New Markets Depends on
the Outcome of the Deregulation Process in Each State."

   We currently offer our electricity products in both Pennsylvania and
California at a guaranteed price based on a specified term, generally one year,
and three years for our Wind for the Future 2.0SM product. When a

customer's initial term   [PRINT ADVERTISEMENT--"NO COAL. NO NUKES. NO KIDDING."
of service expires, we                     --APPEARS HERE]
offer products for
continued service that are priced based upon market prices available at that
time. Our customers may switch to another electricity supplier at any time,
although there is a small termination fee for the Wind for the Future 2.0SM
product.

   Our strategy has been to obtain supply contracts that obligate wholesale
suppliers to provide electricity meeting our specifications sufficient to meet
all requirements of a specified number of customers for the full term of our
arrangement with those customers. These requirements contracts generally provide
that during the relevant term the suppliers will deliver into the electricity
distribution system a volume of electricity having the characteristics of the
product selected by the customer equal to the amount of electricity used by the
customer during the service term. These supply contracts also require our
suppliers to provide all associated services, including transmission, scheduling
and settlement services, as applicable. These contracts are not generally
dependent on any minimum number of customers being assigned to them and permit
us to service customers throughout a state.

   We originally entered into three agreements with major wholesale electricity
suppliers to serve the requirements of our Pennsylvania customers. Under these
agreements, each supplier agreed to provide an amount of electricity that
matches the requirements of each customer assigned to that supplier for a
period of twelve months. For two of the agreements, either we or the supplier
may discontinue the assignment of additional customers

                                                                  Choose wisely.
<PAGE>


upon three months' notice. After the assignment of additional customers has
been discontinued, these suppliers will be obligated to continue to provide
electricity to us in an amount that matches the requirements of each customer
that was previously assigned to that supplier for the remainder of that
customer's twelve-month period, whereupon the supply contract will terminate.
These supply contracts may also be terminated by either party if an event of
default occurs relating to the other party. The third agreement provided for
the assignment of customers from January 1, 1999 to March 31, 1999 and, under
that agreement, the supplier is obligated to provide an amount of electricity
that matches the requirements of each customer assigned to that supplier for a
period of twelve months. We are now assigning new customers in the areas served
by this supplier to one of the other existing suppliers referred to above.

   We have entered into agreements with two wholesale electricity suppliers to
serve the requirements of our California customers. Under both of these
agreements, the wholesale price is based on a fixed price spread related to the
wholesale electricity price in California as determined by the California power
exchange. One of these agreements provides for a surcharge on the Wind for the
Future  SM wind power product. Under one of these agreements, the supplier has
agreed to provide to us electricity in an amount that matches the requirements
for each customer assigned to it for a period of twelve months, and either
party may discontinue the assignment of additional customers upon three months'
notice. After the assignment of additional customers has been discontinued,
this supplier will be obligated to provide us an amount of electricity that
matches the requirements of each customer that was previously assigned to the
supplier for the remainder of that customer's twelve-month period, whereupon
the supply contract will terminate. Under the other agreement, the supplier
provides electricity for one- and three-year service periods, depending on the
product being served, and may be assigned additional customers through December
31, 1999. The term of this agreement terminates on the earlier of the
expiration of the term of the last customer assigned to the agreement or
December 31, 2002 with respect to some products and December 31, 2005 with
respect to others. Both of these agreements generally provide that either party
may terminate the agreement if an event of default occurs relating to the other
party.

   Total payments under our electricity supply contracts for 1998 were
approximately $992,181 and for the three months ended March 31, 1999 were
$2,728,125.

   Our contracts with four suppliers provide for separate letters of credit or
equivalent financial assurances to satisfy credit requirements. The amounts of
the letters of credit range from 15 days' to two months' of receivables based
on our load forecast. In addition, we have delivered to one supplier
irrevocable letters of credit in connection with the supplier's purchase and
installation of three wind power turbines. We also delivered letters of credit
to regulators securing our performance as an energy service provider. Total
supply and regulatory letters of credit outstanding at December 31, 1998 were
$2,765,230 and at March 31, 1999 were $2,477,251.

   With the exception of minor costs associated with specialty content that
makes up less than 15% of our electricity requirements and limited reservation
and liquidation fees, to date we have avoided taking on electricity supply
costs that are not tied directly to customer sales volumes. As described above,
under our supply contracts the price we pay for electricity is either fixed or,
in California, based on the price established by the California Power Exchange
plus a specified amount. Because the price terms for our customers reflect our
wholesale price of the electricity plus a retail margin and the term of our
supply contract is coextensive with the term of the contract with our customer,
we generally are not at risk that the wholesale price of power will exceed the
price to be paid by our customers. In the future, as our electricity
requirements reach substantial levels, we may increase the volume of
electricity contracts that we buy directly from electricity generators and
wholesale marketers in order to reduce our overall costs of electricity supply
and allow us greater marketing flexibility. We believe that we will be able to
obtain sufficient electric power to meet our supply needs, both for our
existing operations in Pennsylvania and California and future operations in new
deregulated electricity markets that we are likely to enter, for the
foreseeable future, although we can provide no assurance in this regard. See
"Risk Factors--Other Risks Related to our Business Generally--Our Existing
Green Electricity Business Depends on our Ability to Obtain from Wholesale
Electricity Suppliers, on Acceptable Terms, Electricity Meeting our Customers'
Requirements" and "Management's Discussion and Analysis of Financial Condition
and Results of Operations."

  Recently Announced Product Offerings

   Credit Cards. We have recently begun to offer, through our Web site, a First
USA credit card that is co-branded with the Green Mountain brand and Visa.
Under our five-year agreement with First USA, we will promote the credit card
to our customers and registered users. First USA is responsible for
applications, provision of credit, billing and collection and related services.
We will be paid a fee for each person who signs up for the credit card, plus a
royalty on credit card purchases. We presently intend to dedicate 25% of these
royalties to environmental activities, including the construction of solar
power generation facilities. We believe this product will foster a sense of
community among our customers and a sense of identification with
GreenMountain.com.

   Ecotourism. We have recently begun to offer, through our Web Site,
ecological tours and vacations arranged by The Green Travel Network. The
product we offer -- ecotourism -- is a nature-based form of specialty travel
that promotes responsible travel aimed at conserving the destination's natural
areas and sustaining the well-being of the local people.

   Electric Bicycles. We have recently begun to offer electric bicycles sold by
ESI Energy Services. Through our Web site, our customers can obtain information
about and order different models of electric bicycles.

   Books. We have recently begun to offer books relating to environmental
topics by partnering with Amazon. com. Our customers through our Web site view
the books on our Web site and then link to Amazon.com's Web site to place their
order.

  Additional Product Offerings Under Consideration

   We do not intend to manufacture any products, but rather will sell products
produced for us by others under the Green Mountain brand. We also expect to
enter into additional relationships with third parties to make their green
products available through our Web site. See "Risk Factors--Risks Related to
Establishment of our Business--Our Ability to Grow our Customer Base and
Generate Sales Depends on Broadening our Product Offerings" and "--Risks
Related to the Internet and Online Commerce Aspects of our Business--Products
Sold by us May Subject us to Litigation and the Related Costs."

   Some of the additional product offerings we have under consideration are
described below.

   Energy Efficient Home Products. We expect to offer on our Web site a home
energy audit feature which will enable visitors to our site to review the
energy efficiency of their home. In conjunction with that feature, we expect to
offer a variety of products principally related to the home which will assist
the user in reducing energy use and expenditures. These will initially consist
of relatively small items such as energy efficient lighting, but we expect to
expand our selection of offerings to include more substantial products such as
major appliances.

   Natural Gas. We are developing a marketing and branding strategy for natural
gas, which is a cleaner fossil fuel that we believe complements our electricity
products. Although the natural gas we would offer would generally not be
different from natural gas offered by other suppliers, we believe customers who
have chosen our electricity products will also be inclined to purchase natural
gas from us. We are also exploring the feasibility of offering a "green gas"
product, which would be a blend of landfill-gas derived fuel (methane) and
standard natural gas.

   Like the electric utility industry, the natural gas utility industry is
being deregulated. We expect to offer retail natural gas products in each state
that deregulates in a manner that we believe will allow us to compete
effectively. Competition has opened in parts of the California and Pennsylvania
residential natural gas markets. We are currently negotiating with natural gas
suppliers in these markets.

   Alternative Fuel Vehicles. We are currently exploring the feasibility of
marketing alternative fuel vehicles. Alternative fuel vehicles are vehicles
that operate using natural gas, ethanol, electricity or propane. There has been
increased attention to development of alternative fuel vehicles by automakers,
which has been primarily due to legislative trends that favor lower emission
vehicles and growing demand from consumers
who care about the environment. We believe that these trends will provide the
opportunity to market these vehicles on an increasingly larger scale.

   Fuel Cells. We are exploring the feasibility of marketing fuel cells--a near
zero-emission electricity generation technology. Fuel cells convert natural
gas, gasoline or hydrogen into electricity without any combustion and the
related harmful by-products of nitrogen or sulfur dioxide. Fuel cells would be
a strong strategic addition to our green electricity products. Delivery of 100%
of the electricity needs of an average-

                                       49

<PAGE>

sized residence would require placement of a fuel cell unit the approximate
size of a dishwasher. Potential residential customers include customers who are
interested in the environmental benefits of fuel cell technology, as well as
rural homes and households that desire back-up or uninterrupted electricity
generation. Our ability to offer fuel cells, as well as other products, is
dependent on technological advances, and we cannot assure you whether or when
those advances will occur. See "Risk Factors--Risks Related to Establishment of
our Business--Our Ability to Grow our Customer Base and Generate Sales Depends
on Broadening our Product Offerings."

   Financial Services. We are considering ways in which we can provide our
customers financial services related to environmentally responsible
investments, such as investments in companies which have a demonstrated record
of environmental accomplishment. The Social Investment Forum's November 1997
Report on Responsible Investing Trends in the United States reported the
existence of $1.2 trillion in professionally managed portfolios incorporating
at least one social investment strategy.

Our Web Site

   Our goal is to create a Web site that will be a state-of-the-art,
interactive commerce platform. In addition to the tools necessary for the sale,
fulfillment and customer service functions, our Web site will offer content and
community features that will appeal to people who are concerned about the
environment. We are depending on Strategic Interactive Group, a specialized Web
site developer, for the upgrade of our Web site. We expect that the current
upgrade of our Web site will be complete by October 1, 1999. See "Risk
Factors--Risks Related to Establishment of our Business--To Attract Customers
and Make Sales Over the Internet, We Must Develop our Web Site and Implement
Ongoing Improvements to our Web Site in the Face of Rapid Technological
Change."

  Strategic Web Site Relationships

   We believe that in order to attract significant traffic to our Web site we
need to establish and maintain relationships with Internet portals and other
high-traffic Web sites that will carry links to our new Web site. For example,
on March 25, 1999, we entered into an Advertising and Promotion Agreement with
Yahoo! becoming Yahoo!'s Premier Merchant for consumer energy. The agreement
provides for the placement of banner advertising and button links promoting our
energy business on Yahoo! properties and delivery of Yahoo! e-mail messages
about our energy business for a one-year period. This one-year period began May
1, 1999. For these services, GreenMountain.com agreed to pay Yahoo! a fixed fee
of $6.0 million and a fee for each new energy service account opened through
promotion provided by Yahoo!, with a cap of $400,000 on the total amount to be
paid for accounts opened. Under the agreement, Yahoo! will market promotions to
its registered users on a geographically-targeted basis. The banner advertising
and button links will be displayed to, and the e-mail will be delivered to,
residents of the states of California, Pennsylvania and New Jersey.
GreenMountain.com has the right to redirect promotions that would otherwise be
directed to New Jersey if New Jersey's deregulation program is delayed more
than one month. See "--Marketing, Sales and Customer Service--Marketing." To
date, other than the Yahoo! agreement, we have not entered into any agreements
with any Internet portals or other high-traffic Web sites.

   We will also need to establish relationships with content providers that
will provide our Web site with content that appeals to environmentally-
conscious consumers. To date, we have entered into content agreements with:

  .Autobytel.com to provide information on fuel efficient vehicles;

  .American Council for an Energy Efficient Economy to provide information on
   vehicle fuel efficiency and emissions ratings for conventional vehicles;
   and

  .SocialFunds.com to provide investment research and analysis regarding
   socially-responsible investments.

See "Risk Factors--Risks Related to Establishment of our Business--Our Failure
to Develop and Maintain Strategic Web Site Relationships Could Adversely Affect
our Ability to Attract Customers to our Web Site."

  Community

   Community will be an integral feature throughout our Web site. We believe
that through community activities such as e-mail newsletters, bulletin boards,
chat forums and eco-greeting cards, customers will have a unique opportunity to
share ideas about environmental issues and marketing solutions. We are
exploring community fostering elements for our Web site, including:

  .A "socially responsible" business opportunities bulletin board;

  .Live chats with environmental experts;

  .Bulletin boards discussing environmental issues;

  .User home pages--that will allow users to create their own home page on
   our Web site;

  .An eco-event locator--that will allow individuals to post and obtain
   information about local, environment-related events;

Information Technology

   Our Information Network electronically routes customer information in a
manner that allows each of our outsourcing partners to efficiently and
effectively perform the specific marketing, sales or customer service function
for which it is responsible. The Information Network also:

  .Collects customer usage information;

  .Communicates billing data;

  .Provides customers with electronic payment options; and

  .Interfaces with local utility distribution companies to share customer
   information.

                                       52

                                                                  Choose wisely.
<PAGE>

   The design of our Information Network gives us the ability to:

  .Service a rapidly growing customer base;

  .Minimize our capital expenditures and reduce fixed costs by outsourcing
   functions that are priced based on variable, per customer or transaction
   charges; and

  .Maximize the expertise and competitive advantages of our outsourcing
   partners.

The use of standard data sets that can adapt to the needs of each outsourcing
partner provides flexibility and allows for significant changes, such as the
replacement of an outsourcing partner, on relatively short notice.

   We are in the process of implementing an enterprise database as part of our
Information Network. This will provide us with the ability to access and
manipulate data that has entered the Information Network on a real time basis
giving us even greater flexibility and control.

   We manage our Information Network with the assistance of Sterling Software,
a supplier of software products and services with expertise in network
management and automation. Products from Sterling Software are used in more
than 90% of the Fortune 100 companies including Ford Motor Company, Wal-Mart
Stores Inc. and Lockheed Martin, and are used in more than 20,000 customer
sites worldwide. For a discussion of our agreement with Sterling Software, see
"Related Party Transactions--Other Transactions and Relationships--Agreements
with Sterling Software."

Our Competitive Position

   Because both the deregulated electricity and online commerce markets are
new, rapidly evolving and highly competitive, we face intense competition and
anticipate that the competition will intensify in the future. Our competitors
and potential competitors include:

  .Companies that offer competitive non-green products, like some of our
   competitors in the deregulated electric utility markets, including Exelon
   and Allegheny Energy in Pennsylvania, both of which are affiliates of
   incumbent electric utilities;

  .Companies that market green products in a single line of business, like
   some of our competitors in the deregulated electric utility markets,
   including Commonwealth Energy in California, that offer only green
   electricity products;

  .Retailers that do not specialize in offering green products, but do
   include one or more green products among their offerings, like some of our
   competitors in the deregulated electric utility markets, including
   Conectiv in Pennsylvania; and

  .Emerging online retailers that specialize in offering electricity
   products.

We also anticipate competition from other retailers attempting to aggregate a
broad selection of green products.

   We currently offer green electricity products in the deregulated utility
markets of Pennsylvania and California. To date, more than 99% of our revenues
have come from sales of our electricity products in those two states. In
Pennsylvania, as of March 31, 1999, approximately 7% of the households in the
Pennsylvania market had switched from their incumbent electricity provider. Of
those that switched from their incumbent electricity providers, approximately
30% switched to green electricity, and of those that switched to green
electricity, approximately 97% switched to us. In California, as of March 31,
1999, only 1% of the households in California had chosen to switch from their
incumbent electricity provider, and of those that had switched, approximately
25% switched to us. In California, all of those that switched are receiving
green electricity.

   We believe that the most significant barrier to entry for a company seeking
to create a national consumer brand in order to compete in deregulated
electricity markets is the significant capital investment necessary for

                                       53

It's a small planet.(SM)
<PAGE>

brand development and technology infrastructure. We believe that the principal
competitive factors in the retail green electricity market are:

  .First mover momentum;

  .Strong brand recognition and presence;

  .Marketing ability;

  .Environmental credibility; and

  .Competitive pricing.

   We are focusing on increasing our Internet presence and expanding our
Internet sales of green electricity and other green products. The online
commerce market has relatively minimal barriers to entry in that current and
new competitors can launch new sites at a relatively low cost. We believe that
the principal competitive factors in the online commerce market include:

  .First mover momentum;

  .Strong brand recognition and presence;

  .Broad product selection;

  .Quality of site experience;

  .Purchasing convenience;

  .Competitive pricing; and

  .Reliability and speed of fulfillment.

   Many of our current and potential competitors have longer operating
histories, larger customer bases, greater brand recognition and significantly
greater financial, marketing and other resources than we do. We may face
increased competitive pressures as new technologies are developed and existing
technologies are improved. See "Risk Factors--Other Risks Related to our
Business Generally--Intense Competition May Affect our Ability to Grow our
Customer Base and Generate Sales."

The Protection Of Our Intellectual Property

   We regard our copyrights, service marks, trademarks, trade dress, trade
secrets and similar intellectual property as critical to our success, and rely
on trademark and copyright law, trade secret protection and confidentiality
and/or license agreements with our employees, strategic partners and others to
protect our intellectual property rights. See "Risk Factors--Other Risks
Related to our Business Generally--Failure to Protect our Intellectual Property
Could Adversely Affect our Brand and our Business."

The Impact Of Government Regulation On Our Business

   In addition to regulations applicable to businesses generally, including
federal and state consumer protection laws and regulations, we are subject to
the laws and regulations applicable to electric power retailers in the
deregulated electric utility markets in which we compete. See "Risk Factors--
Risks Related to Establishment of our Business--Our Ability to Expand our
Existing Electricity Business into New Markets Depends on the Outcome of the
Deregulation Process in Each State." We are also subject to laws and
regulations applicable to online commerce. See "Risk Factors--Risks Related to
the Internet and Online Commerce Aspects of our Business--Government Regulation
of the Internet and Online Commerce is Still Developing and Could Increase our
Operating Costs or Otherwise Adversely Affect our Business."

Our Employees

   As of March 31, 1999, we employed 68 full-time employees and seven temporary
employees. None of our employees is represented by a labor union, and we
consider our relations with employees to be good.

                                       54

                                                                  Choose wisely.

The Facilities Used In Our Business

   Our headquarters are located in South Burlington, Vermont. We lease
approximately 16,000 square feet of space, which houses our administrative,
sales and marketing and operations and support staffs under a cancelable
operating lease that expires on September 30, 2002. Future minimum lease
payments required at December 31, 1998, assuming that we do not cancel the
lease, were $114,675 in each of 1999, 2000 and 2001 and $86,006 in 2002. The
lease agreement has a termination provision that enables us to terminate the
lease at (1) September 30, 1999 and pay an early termination payment of
$33,000, (2) September 30, 2000 and pay an early termination payment of
$25,000, and (3) September 30, 2001 and pay an early termination payment of
$12,500. We anticipate that we will require additional space within the next
six months, but that suitable additional space will be available at reasonable
cost.

   Each member of the Environmental Advisory Board serves in his individual
capacity and not as a representative of the organization with which he is
affiliated. We currently have no standard arrangement under which we compensate
members of our Environmental Advisory Board, except that we reimburse them for
their out-of-pocket expenses incurred in connection with their service on the
Environmental Advisory Board. Members of the Environmental Advisory Board will
be eligible to receive stock option grants under our 1999 Stock Option Plan.
See "--Stock Option Agreements and Plans--1999 Stock Option Plan."

   We are actively recruiting additional environmental experts and leaders to
serve on the Environmental Advisory Board. In addition, we intend to broaden
the scope of the Environmental Advisory Board to include, or create one or more
new advisory boards that will include, members who will provide expert advice
on technical and business matters. Accordingly, we are recruiting technical and
business advisors for that purpose.

Director Compensation

   Each director will be paid a semi-annual retainer in the form of shares of
unrestricted common stock having a fair market value of $15,000. The fair
market value per share for the six-month retainer period beginning January 1
and ending June 30 of each year will be equal to the closing price of the
common stock on the last trading day of the preceding calendar year, and the
shares for the retainer period will be issued to the directors as soon as
practicable after January 1 of each year. The fair market value per share for
the six-month retainer period beginning July 1 and ending December 31 will be
equal to the closing price of the common stock on the last trading day
preceding July 1, and the shares for the retainer period will be issued to the
directors as soon as practicable after July 1 of each year.

   If a director is first elected to the board of directors after the first day
of a retainer period, he or she will receive, as soon as possible after the
election, a pro rata portion of the semi-annual retainer for that retainer
period based on the number of days remaining in the period, and the fair market
value per share will be equal to the closing price of the common stock on the
last trading day preceding the date of the director's election to the board of
directors.

   The shares of common stock issued to each director in payment of the
director's retainer will not be subject to forfeiture if the director ceases to
be a member of the board of directors. However, if a director ceases to be a
director before the last day of a retainer period other than by reason of
death, disability or retirement from the board of directors at or after age 65,
he or she will be required to pay the company in cash an amount equal to the
unearned portion of the $15,000 retainer based on the number of days remaining
in the retainer period.

   We have reserved 150,000 shares for issuance under the 1999 Director Stock
Award Plan, subject to adjustment as provided in the plan.

   In addition, each director will receive $2,000 in cash for each board of
directors meeting attended and for each committee meeting attended on days on
which the board of directors does not also meet. We also reimburse directors
for out-of-pocket expenses incurred in connection with attending board of
directors and committee meetings.

   Directors will also be eligible to receive stock option grants under our
1999 Stock Option Plan. See "-- Stock Option Agreements and Plans--1999 Stock
Option Plan." Those persons who have become or are expected to become directors
of GreenMountain.com have been granted options to purchase units in the limited
liability company. See "Principal Stockholders."

Employment Agreements

  Agreement With Vice Chairman

   We have entered into a letter agreement, dated February 5, 1999, and amended
June 1, 1999 with Dennis M. Crumpler relating to his service to us as a
director, Vice Chairman, Chairman of the Executive Committee and consultant.
Under the agreement, Mr. Crumpler purchased an equity interest under our
Employee Unit Purchase Plan. See "Related Party Transactions--Subsequent
Transactions--Employee Unit Purchase Plan." In connection with the execution of
the agreement, in February 1999, we granted him an option exercisable to
purchase 60,000 shares of common stock at an exercise price of $3.33 per share
in connection with his service as a director. See "Management--Director
Compensation." At that time, we also granted him an option exercisable to
purchase 427,500 shares of common stock at an exercise price of $3.33 per share
in connection with his service as Vice Chairman. Under the agreement as
amended, and subject to the approval of the Special Compensation Committee, we
expect to grant him additional options to purchase 60,000 shares in connection
with his service as a director and 427,500 shares in connection with his
service as Vice-Chairman and Chairman of the Executive Committee, in each case
at an exercise price per share equal to the initial public offering price.
These options provide or will provide for vesting as to 20% of the underlying
equity interest on the date of grant and vesting as to 5% of the underlying
equity interest on the first day of each of the next 16 calendar quarters.

  Employment Agreement With Our Chief Executive Officer

   On October 5, 1998, we entered into an employment agreement with M. David
White, our Chief Executive Officer. The agreement provides that Mr. White will
receive an initial annual base salary of $155,000 and an annual incentive bonus
payable at the discretion of our board of directors. Mr. White did not receive
a bonus for 1998. In addition, he receives an annual expense allowance of up to
$50,000 for transportation and housing. Mr. White also receives health, term
life and disability insurance and is eligible to participate in other benefit
plans made available to our senior executives.

   Under the agreement, Mr. White purchased an equity interest under our
Employee Unit Purchase Plan. See "Related Party Transactions--Subsequent
Transactions--Employee Unit Purchase Plan." Under the agreement, in January
1999 we granted him an option exercisable to purchase 900,000 shares of common
stock at an exercise price of $3.33 per share. This option provides for vesting
as to 20% of the underlying equity interest on February 2, 1999 and vesting as
to 5% of the underlying equity interest on the first day of each of

                                       64

                                                                  Choose wisely.

the next 16 calendar quarters. In addition, pursuant to antidilution provisions
of the agreement, in connection with the completion of a private equity
offering in February 1999 we granted him an option exercisable to purchase
225,000 shares of common stock at an exercise price of $6.67 per share. This
option provides for vesting as to 20% of the underlying equity interest on the
date of grant and vesting as to 5% of the underlying equity interest on the
first day of each of the next 16 calendar quarters.

   Mr. White's employment agreement provides for his employment until December
31, 2003, but his employment may be terminated earlier by either party. If we
terminate his employment for cause or he terminates his employment without good
reason, he will receive no further compensation or other benefits from us,
except compensation that has been accrued but not paid and benefits that we are
required by law to continue. If we terminate his employment without cause or he
terminates his employment with good reason, he will receive salary and
benefits, including health, life and disability insurance, for up to one year
following his termination and, if no member of the Wyly family is chairman of
the board of directors of GreenMountain.com, the options granted to him as
described above will immediately vest and be exercisable.

Agreement Between Highland Stargate And Our Chief Executive Officer

   At the time he accepted his position with us, David White, our Chief
Executive Officer, also entered into an agreement with Highland Stargate, an
entity controlled by the Wyly family. That agreement contemplates that
Mr. White will provide investment advisory services to Highland and its
affiliates, but expressly provides that performance of those services will not
interfere with the performance by him of his duties to us on a substantially
full-time basis. In consideration for his services, Highland agreed to pay Mr.
White an amount sufficient to cause Mr. White's total annual compensation from
Highland, its affiliates and GreenMountain.com to equal not less than
$1,000,000 for the years 1999 through 2003 and a similar prorated amount for
that portion of 1998 subject to the agreement. Highland also agreed to lend
Mr. White $3,000,000 for the purpose of refinancing outstanding indebtedness
and making investments. Highland further agreed to provide Mr. White investment
opportunities, including the opportunity to invest in any significant new
venture of any Highland affiliate on a cost basis similar to Highland and its
affiliates. The loans to Mr. White bear interest at 6%, compounded annually,
are recourse and are secured by real estate and specified investment securities
owned by Mr. White including stock and options issued by us.

   Highland agreed to reimburse Mr. White's business expenses incurred on its
behalf and to provide health and similar insurance benefits substantially
similar to those contemplated in his agreement with us if we do not provide
them. The agreement contains provisions related to confidentiality,
noninterference by Mr. White in Highland's business, indemnification of
Mr. White against claims resulting from his employment by Highland and other
matters of a nature commonly found in agreements of this type.

   Mr. White's Highland agreement provides for his employment until
December 31, 2003. Upon termination of his employment by Mr. White, by Highland
for cause or as a result of death or disability, the agreement provides that
Mr. White will receive no further compensation except for compensation that has
accrued prior to termination and for benefits required by law. Upon termination
by Highland without cause, the agreement further provides for the payment of
aggregate salary and bonus compensation which he would otherwise have been
entitled to receive through December 31, 2003. The contract further provides
that the compensation obligations of Highland to Mr. White will be deemed
satisfied if Mr. White's realized and unrealized profits with respect to
specified investment securities securing the loans described above exceed
$10,000,000.

Agreement Between Highland Stargate And Our Chief Financial Officer

   At the time he accepted his position with us Scott Canon, our Chief
Financial Officer, entered into a substantially similar agreement with
Highland. Mr. Canon's agreement provided that Mr. Canon would receive a minimum
of $500,000 per year for the years 1999 through 2002, together with an amount
of $1,250,000 if GreenMountain.com becomes bankrupt or insolvent, or has been
liquidated or dissolved, on or before December 31, 2003. Mr. Canon's agreement
with Highland does not provide for loans. Highland's obligation to

                                       65

pay compensation to Mr. Canon will be deemed satisfied if his realized and
unrealized profits with respect to investment in fully transferable
GreenMountain.com securities shall exceed $5,000,000 for ten consecutive days
following consummation of an initial public offering.

  Employment Agreements With Other Executive Officers

   On August 6, 1997, in connection with our initial formation we entered into
a three-year employment agreement with each of Thomas C. Boucher, Kevin W.
Hartley, Douglas G. Hyde, David B. Luther and Peter H. Zamore. Each of these
agreements provides that the executive will receive a minimum specified annual
salary and will be entitled to participate in any benefit plan made generally
available by us to our executives and key management employees. The minimum
specified annual salaries are as follows:

   During 1998, each of these executives was paid a salary equal to his base
salary and each of these executives, other than Mr. Hyde, who received no bonus
for 1998, received bonuses for 1998 as follows: Mr. Hartley, $125,000; Mr.
Boucher, $45,000; Mr. Luther, $45,000; and Mr. Zamore, $45,000. The bonuses
were determined by the management committee of the limited liability company on
a case-by-case basis based on each executive's contribution to the limited
liability company; the bonus awards were not tied to any specific performance
or similar criteria.

   If we terminate the executive's employment for cause or the executive
terminates his employment without good reason, we have no further obligations
under the agreement other than to pay the executive's salary through the date
of termination. If we terminate the executive's employment without cause or the
executive terminates his employment for good reason, we are required to
continue to pay the executive an amount equal to his salary and provide medical
and dental insurance coverage for up to one year following termination.

   Contemporaneously with the execution and delivery of these employment
agreements on August 6, 1997, each of these executives was granted an option
exercisable to purchase the number of shares indicated below at an exercise
price of $75.40 per share:

These options provide for vesting as to 20% of the underlying equity interest
on the date of grant and vesting as to 20% of the underlying equity interest on
each of the first four anniversaries of the grant date. In addition, the
unvested portion of these options becomes immediately exercisable upon the
closing of this offering.

   On October 6, 1998, we entered into a separation agreement and release with
Mr. Hyde. Under that agreement Mr. Hyde resigned as our President, but
continued as our employee at the level of compensation provided in his
employment contract until April 6, 1999. We made an initial cash payment of
$142,500 to him shortly after the execution of the agreement, a second cash
payment of $142,500 to him shortly after December 31, 1998 and a third cash
payment of $142,500 to him in April 1999. The agreement provides that

his option granted on August 6, 1997, to the extent vested on April 6, 1999,
will remain exercisable until August 6, 2002. Under the agreement, he was
permitted to invest under the Employee Unit Purchase Plan. See "Related Party
Transactions--Subsequent Transactions--Employee Unit Purchase Plan." Under the
agreement, Mr. Hyde is prohibited from engaging in some competitive activities
and from recruiting our employees and soliciting our customers during the two-
year period ending April 6, 2001.

Stock Option Agreements And Plans

  Options Granted Upon Formation Of The Limited Liability Company

   On August 6, 1997, options were granted to officers and advisors of the
limited liability company in connection with its formation. These grants are
evidenced by Operating Management Option Agreements and Supervisory Management
Option Agreements dated as of August 6, 1997. As of March 31, 1999, there were
outstanding under these agreements options exercisable for 47,883 shares of
common stock at an exercise price of $75.20 per share and options exercisable
for 34,029 shares of common stock at an exercise price of $75.40 per share. See
"Management--Employment Agreements--Employment Agreements with Other Executive
Officers" and "Shares Eligible for Future Sale."

  1997 Employee Ownership Plan

   In 1997, our predecessor adopted a 1997 Employee Ownership Plan. Under the
1997 Employee Ownership Plan, our predecessor from time to time granted options
to employees who had not previously entered into an agreement concerning an
option to purchase interests in the limited liability company. Options were
granted under the 1997 Employee Ownership Plan during the fiscal year ended
December 31, 1998 on a case-by-case basis. Based on input from the executive
officers, the management committee of the limited liability company considered
the contributions of each recipient to the limited liability company in making
the grants. In addition, to attract the talent necessary to enhance our growth,
the management committee considered the potential contributions of the
individuals in granting options to new employees.

   As of March 31, 1999, there were outstanding under the 1997 Employee
Ownership Plan options exercisable for 7,917 shares of common stock at an
exercise price of $75.40. No additional options are expected to be granted
under the 1997 Employee Ownership Plan. See "Shares Eligible for Future Sale."

  1999 Unit Option Plan

   In 1999, our predecessor adopted a 1999 Unit Option Plan pursuant to which
the management committee or the committee administering the plan could
designate individuals eligible to receive options. Under the 1999 Unit Option
Plan, our predecessor granted options to directors, executive officers,
employees and consultants. As of March 31, 1999, there were outstanding under
the 1999 Unit Option Plan options exercisable for 4,835,400 shares of common
stock at an exercise price of $3.33 and 1,062,000 shares of common stock at an
exercise price of $6.67. Since March 31, 1999, options to purchase an
additional 78,000 shares at an exercise price of $13.33 and 135,000 shares at
an exercise price of $12.00 have been granted in connection with the hiring of
new employees. See "Shares Eligible for Future Sale."

   Grants, including grants to members of the management committee of the
limited liability company, made under the 1999 Unit Option Plan were approved
by the management committee of the limited liability company. The intent of the
management committee in making grants is to attract and retain the best
available talent and encourage the highest level of performance by providing an
opportunity to participate in any increase in our equity value. Based on input
from the executive officers, the management committee considered the
contributions of each recipient to the limited liability company in making the
grants. In addition, the management committee considered the economic
incentives necessary to attract directors, executive officers and employees to
a company of our size and limited operating history.

  1999 Stock Option Plan

   Prior to the closing of this offering, we will adopt a 1999 Stock Option
Plan, which will amend and restate the 1997 Employee Ownership Plan and the
1999 Unit Option Plan. The purpose of the 1999 Stock Option Plan is to attract
and retain the best available talent and encourage the highest level of
performance by executive officers, key employees, directors, advisors and
consultants, and to provide them with incentives to put forth maximum efforts
for the success of our business, in order to serve the best interests of
GreenMountain.com and its stockholders. We expect that option grants under the
1999 Stock Option Plan will be a key element of our compensation strategy, and
that we will utilize the reservation of shares under the 1999 Stock Option
Plan to the maximum extent practicable. Subject to the approval of the Special
Compensation Committee and our board of directors, we expect in connection
with this offering to grant to Sam Wyly an option to purchase 625,000 shares
of common stock, to Dennis Crumpler an option to purchase 487,500 shares of
common stock and to Dennis Kelly an option to purchase 675,000 shares of
common stock, in each case at an exercise price per share equal to the initial
public offering price. These options will vest as to 20% of the underlying
shares on the date of grant and will vest as to 5% of the underlying shares on
the first day of each of the next 16 calendar quarters. Further, we expect
that, following the closing of this offering our directors who are actively
involved in the management of our business and our executive officers will
from time to time receive substantial option grants.

   Administration. The 1999 Stock Option Plan will be administered by the
Special Compensation Committee or the full board of directors.

   Options. The 1999 Stock Option Plan will authorize the grant of stock
options to purchase shares of GreenMountain.com common stock. Grants under the
1999 Stock Option Plan are not intended to qualify as incentive stock options
under Section 422 of the Internal Revenue Code.

   Number of Shares Reserved. The total number of shares of common stock that
will be available for issuance under the 1999 Stock Option Plan is 12,554,713.
However, this number will be increased, if necessary, on the last date of each
fiscal quarter so that the sum of:

  (1) the total number of shares of common stock previously issued upon the
      exercise of stock options;

  (2) the total number of shares of common stock then subject to outstanding
      stock options; and

  (3) the total number of shares of common stock then remaining available
      under the 1999 Stock Option Plan to be made subject to future grants of
      stock options

equals 20% of the total number of outstanding shares of common stock of
GreenMountain.com, computed on a fully-diluted basis.

   The Special Compensation Committee and the board of directors may make
additional adjustments in the maximum number of shares available under the
1999 Stock Option Plan or in the number of shares of common stock covered by
outstanding options, in the purchase price per share of common stock covered
by options, and/or in the kind of shares covered (including shares of another
issuer), as the Special Compensation Committee or the board of directors in
its sole discretion, exercised in good faith, may determine is equitably
required to prevent dilution or enlargement of the rights of 1999 Stock Option
Plan participants resulting from any change in our capital structure, merger,
consolidation, spin-off, reorganization, liquidation, issuance of rights or
warrants to purchase securities or any other corporate transaction or event
having a similar effect.

   Eligibility. Our executive officers, key employees, directors, advisors and
consultants, and prospective employees, directors, advisors and consultants,
will be eligible to receive grants of stock options.

   Transferability. Each option granted pursuant to the 1999 Stock Option Plan
may be subject to any transfer restrictions as the Special Compensation
Committee or the board of directors determines.

                                      68

                                                                 Choose wisely.

   Description of Awards. The 1999 Stock Option Plan will not specify a maximum
term for stock options. The exercise price of the options may not be less than
the fair market value per share of common stock on the grant date. The Special
Compensation Committee or the board of directors may, without the consent of
the holder of an option, amend the terms of the option in several respects,
including acceleration of the time at which the option may be exercised,
extension of the expiration date, reduction of the exercise price and waiver of
other conditions or restrictions.

   Each grant of options will specify the number of shares of common stock, the
exercise price and any vesting schedule and state whether the exercise price is
payable in cash, by the actual or constructive transfer to GreenMountain.com of
nonforfeitable, unrestricted shares of common stock already owned by the
participant having an actual or constructive value as of the time of exercise
equal to the total exercise price, by any other legal consideration authorized
by the Special Compensation Committee or the board of directors or by a
combination of such methods of payment.

   The maximum aggregate number of shares of common stock with respect to which
options may be granted to any participant during any single calendar year will
not exceed 3,159,156.

   Vesting of Options Upon a Change in Control. The stock option agreement
evidencing any stock option granted under the 1999 Stock Option Plan may
provide that the stock option will become exercisable if there is a change in
control of GreenMountain.com or in the event of similar transactions or events.
The specific terms of any such provision will be set forth in the stock option
or other agreement or in any agreement.

   Amendment and Termination. The board of directors may amend or terminate the
1999 Stock Option Plan at any time. The termination of the 1999 Stock Option
Plan will not adversely affect the terms of any outstanding options. If any
law, rule or regulation removes or lessens any restrictions imposed for
options, the Special Compensation Committee or the board of directors may amend
the 1999 Stock Option Plan and all options then outstanding will be subject to
such amendment.

   Grants Under the Plan. No options have been granted under the 1999 Stock
Option Plan and it is not possible to determine the specific awards of options
that will be granted to various individuals in the future under the 1999 Stock
Option Plan. However, we expect to issue options under the 1999 Stock Option
Plan to Sam Wyly, Dennis Crumpler and Dennis Kelly as indicated above.

Compensation Committee Interlocks And Insider Participation

   The limited liability company does not have a compensation committee.
Decisions regarding compensation have been made by the full management
committee of the limited liability company, including Sam Wyly, the Chairman of
that committee. Mr. Wyly may be deemed to be an executive officer of the
limited liability company because of policy making functions performed by him
as Chairman of its management committee.

   Sam Wyly is an executive officer and director of Sterling Software and
Michaels Stores. He serves as a member of the executive committee and stock
option committee of Sterling Software and as a member of the compensation
committee of Michaels Stores. Accordingly, Sam Wyly has participated in
decisions related to compensation of executive officers of each of
GreenMountain.com, Sterling Software and Michaels Stores.

   Other than Sam Wyly, who may be deemed to have been an executive officer,
none of the limited liability company's executive officers has served on the
compensation committee, or on any full board of directors or other board
committee that performs functions similar to a compensation committee, of any
entity that has one or more of its executive officers who has served as a
member of the limited liability company's management committee.

Limitation Of Liability And Indemnification Matters

   Prior to the closing of this offering, our certificate of incorporation and
bylaws will be amended. Our amended certificate will limit the liability of our
directors to the maximum extent permitted by Delaware law. Delaware law
provides that a director of a corporation will not be personally liable for
monetary damages for breach of that individual's fiduciary duties as a director
except for liability for any of the following:

  .a breach of the director's duty of loyalty to the corporation or its
   stockholders;

  .any act or omission not in good faith or that involves intentional
   misconduct or a knowing violation of the law;

  .unlawful payments of dividends or unlawful stock repurchases or
   redemptions; or

  .any transaction from which the director derived an improper personal
   benefit.

This limitation of liability does not apply to liabilities arising under
federal securities laws and does not affect the availability of equitable
remedies such as injunctive relief or recission.

   Section 145 of the Delaware General Corporation Law provides that a
corporation may indemnify directors and officers, as well as other employees
and individuals, against attorneys' fees and other expenses, judgments, fines
and amounts paid in settlement actually and reasonably incurred by such person
in connection with any threatened, pending or completed actions, suits or
proceedings in which such person was or is a party or is threatened to be made
a party by reason of such person being or having been a director, officer,
employee or agent of the corporation. The Delaware General Corporation Law
provides that Section 145 is not exclusive of other rights to which those
seeking indemnification may be entitled under any bylaw, agreement, vote of
stockholders or disinterested directors or otherwise.

   Our amended certificate and amended bylaws will provide that we are required
to indemnify our directors and officers to the maximum extent permitted by law.
Our amended bylaws will also require us to advance expenses incurred by an
officer or director in connection with the defense of any action or proceeding
arising out of that party's status or service as a director or officer of
GreenMountain.com or as a director, officer, employer or agent of another
corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise, if serving as such at our request. Our amended bylaws will also
permit us to secure insurance on behalf of any director or officer for any
liability arising out of his or her actions in a representative capacity.

   We intend to enter into indemnification agreements with our directors and
some of our officers containing provisions that:

  .indemnify, to the maximum extent permitted by Delaware law, those
   directors and officers against liabilities that may arise by reason of
   their status or service as directors or officers, except liabilities
   arising from willful misconduct of a culpable nature;

  .to advance their expenses incurred as a result of any proceeding against
   them as to which they could be indemnified; and

  .to obtain directors' and officers' liability insurance if maintained for
   other directors or officers.

   We believe that the provisions of our certificate of incorporation and
bylaws described above and indemnification agreements are necessary to attract
and retain qualified persons as directors and officers. The limited liability
company currently has liability insurance for its management committee members
and officers and we intend to obtain directors' and officers' liability
insurance for directors and officers of GreenMountain.com.

                        RELATED PARTY TRANSACTIONS

Formation Of The Business

  Background Of The Business

   Between 1994 and 1997, an affiliate of Green Mountain Power Corporation
conducted extensive market research to evaluate the viability of a nationally-
marketed, premium-priced green electricity product supported by a strong pro-
environmental brand identity. This market research was designed to identify:

  .The most attractive consumer segments;

  .The key elements of environmental positioning; and

  .The optimal design of potential green electricity products.

   An affiliate of Green Mountain Power Corporation also participated, together
with 20 other companies, in deregulated energy pilot programs in Massachusetts
and New Hampshire in order to test the viability of marketing green electricity
and natural gas products.

  Formation Of The Limited Liability Company

   On August 6, 1997, a subsidiary of Green Mountain Power Corporation and
Green Funding I entered into a limited liability company agreement relating to
the formation of Green Mountain Energy Resources L.L.C.

   Limited Liability Company Agreement. Under the limited liability company
agreement:

  .The subsidiary of Green Mountain Power Corporation contributed service
   marks, including our "Choose wisely. It's a small planet." and "Green
   Mountain Energy Resources" service marks, some marketing studies and
   analyses and its rights under agreements with several third-party service
   providers, in exchange for a 33% equity interest in the limited liability
   company;

  .Green Funding I contributed $8.0 million and committed to contribute an
   additional $22.0 million over time, in exchange for a 67% equity interest
   in the limited liability company; and

  .Immediately following the initial contribution by Green Funding I, the
   subsidiary of Green Mountain Power Corporation received a distribution
   from the limited liability company of $4.0 million.

   The limited liability company agreement also contained provisions relating
to, among other things, the allocation of profits and losses, the management of
the limited liability company, restrictions on transfer and registration
rights.

   Non-Compete and Name Use Agreement. In connection with the formation of the
limited liability company, on August 6, 1997, Green Mountain Power Corporation,
Green Funding I and the limited liability company entered into an agreement
containing:

  .Covenants by Green Mountain Power Corporation and Green Funding I
   generally not to engage in the retail energy business, subject to
   exceptions related to Green Mountain Power Corporation's then-existing
   business activities;

  .Covenants by Green Mountain Power Corporation and Green Funding I not to
   use the Green Mountain name in connection with business activities similar
   to those conducted by the limited liability company; and

  .Other covenants by Green Mountain Power Corporation relating to the use of
   the Green Mountain name.

   Transfer of Employees. In connection with the formation of the limited
liability company, on or about August 6, 1997, some individuals who were
employed by Green Mountain Power Corporation ceased their employment with that
company and became employees of the limited liability company. These
individuals included Ms. Blunden, Mr. Boucher, Mr. Hartley, Mr. Hyde, Mr.
Luther, Ms. O'Neill, Mr. Rawls and Mr. Zamore.

Subsequent Transactions

  September 1997 Capital Infusion

   On September 29, 1997, Green Funding I committed an additional $10.0 million
to the limited liability company in exchange for an additional equity interest
in the limited liability company, raising Green Funding I's total equity
interest to approximately 73%.

  August 1998 Short-Term Loan

   On August 26, 1998, the limited liability company arranged to borrow $10.0
million from Security Capital, Ltd. This loan, which bore interest at a rate of
10% per annum, was made by Security Capital, Ltd. Several entities, whose stock
is owned by irrevocable trusts of which members of the Wyly family are
beneficiaries, provided credit enhancement for the loan. The loan from Security
Capital was repaid in full as described below effective as of November 25,
1998. Total interest paid on that loan was $167,083.

  November 1998 Capital Infusion

   On November 20, 1998, Green Funding I committed an additional $20.0 million
to the limited liability company in exchange for an additional equity interest
in the limited liability company, raising Green Funding I's total equity
interest to approximately 99%. This contribution consisted of the payment in
full of the $10.0 million short-term note described above for the benefit of
the limited liability company and $10.0 million in cash.

  December 1998 Repurchase Of Green Mountain Power Corporation's Equity
Interest

   On December 23, 1998, Green Mountain Power Corporation, its subsidiaries,
Green Funding I and the limited liability company entered into an agreement
that provided for the termination of the non-compete and name use agreement
described above and the repurchase by the limited liability company of the
remaining approximately 1% equity interest held by the subsidiary of Green
Mountain Power Corporation. Under this agreement:

  .Green Mountain Power Corporation agreed not to engage in the unregulated
   marketing or retail sale of electricity or gas outside Vermont for seven
   years;

  .Green Mountain Power Corporation agreed not to use the Green Mountain
   name, subject to a limited exception for activities in Vermont;

  .The subsidiary of Green Mountain Power Corporation transferred to the
   limited liability company its remaining equity interest, withdrew as a
   member and caused its representative on the management committee of the
   limited liability company to resign;

  .The limited liability company agreed to pay Green Mountain Power
   Corporation $1,000,000 in cash; and

  .There were mutual releases granted between Green Funding I and the limited
   liability company, on the one hand, and Green Mountain Power Corporation
   and its subsidiaries, on the other hand.

   As of January 1999, Green Funding I owned 100% of the equity interests in
the limited liability company represented by 6,000,000 common units.

  Employee Unit Purchase Plan

   During January and early February 1999, pursuant to our Employee Unit
Purchase Plan, 50 employees, consultants and advisors purchased 956,000 common
units in the limited liability company in the aggregate for total consideration
of $9.56 million. Upon our conversion from a limited liability company to a
corporation, these 956,000 common units will be converted to 2,868,000 shares
of common stock. Under the Employee Unit Purchase Plan, participants were
permitted to pay for the common units purchased with cash or promissory

notes, or with any combination of cash and promissory notes. Promissory notes
used to pay for the equity interests bear interest at 6% per annum and become
payable on the earliest of the obligor's death, termination of the obligor's
employment or services and December 31, 2003. On each of the first four
anniversaries of the date of the note, accrued and unpaid interest will be
added to principal. The notes are secured by all equity interests that the
participant currently owns, including those acquired under the Employee Unit
Purchase Plan, and all equity interests that the participant acquires in the
future, but are otherwise non-recourse to the obligor. The equity interests
securing these notes are held in escrow for our benefit. The following table
sets forth, for the persons named, the number of shares purchased and the
aggregate amount and type of consideration paid for them.

</TABLE>

   During this same period, 12 of our consultants and advisors purchased, in a
private equity offering, 44,000 common units in the limited liability company
in the aggregate for total consideration of $440,000. Upon our conversion from
a limited liability company to a corporation these 44,000 common units will be
converted into 132,000 shares of common stock.

  Private Equity Offering

   On February 17, 1999, the limited liability company closed a private equity
offering. Investors in the offering purchased 1,515,500 common units in the
limited liability company in the aggregate for total consideration of $30.31
million. Upon our conversion from a limited liability company to a corporation,
these 1,515,500 common units will be converted into 4,546,500 shares of common
stock. As a result of such purchases, Maverick Capital became the beneficial
owner of 750,000 common units, which will be represented by 2,250,000 shares
upon our conversion from a limited liability company to a corporation, for an
aggregate purchase price of $15.0 million. Evan Wyly is a Managing Partner and
Lee Hobson is a Partner of Maverick Capital. In addition, Green Funding II
acquired directly 500,000 common units, which will be represented by 1,500,000
shares upon our conversion from a limited liability company to a corporation,
for an aggregate purchase price of $10.0 million.

  Working Capital Funding Commitment

   Pursuant to an agreement entered into in April 1999, Green Funding I has
committed to provide us with up to $22.0 million in cash to permit us to meet
our working capital needs for the remainder of our 1999 fiscal year. Any
advances under the agreement will bear interest at 6.0% per annum. The
agreement provides that accrued and unpaid interest will be capitalized and
added to principal on each June 30 and December 31.

                                       75

<PAGE>


Principal, together with accrued and unpaid interest, will be payable on the
earlier of April 23, 2001 or the tenth day after the closing of this offering.
Green Funding's obligation to make advances under the agreement terminates upon
the closing of this offering. See "Use of Proceeds."

Reorganization Transaction

   Prior to the closing of this offering, we will convert our business from a
limited liability company to a corporation in order to have a business
organization form that is more typical of other publicly traded entities. This
conversion will be accomplished by merging Green Mountain Energy Resources
L.L.C., a Delaware limited liability company, into GreenMountain.com Company, a
Delaware corporation. In connection with the conversion, the limited liability
company agreement will terminate, except for covenants that, by their terms,
require performance after the termination of such agreement, and each common
unit in the limited liability company held by a member will be exchanged for
three shares of GreenMountain.com common stock. In addition, all outstanding
options and warrants exercisable for common units in the limited liability
company will, in effect, be converted into options or warrants exercisable for
GreenMountain.com common stock.

   The former members of the limited liability company will have registration
rights with respect to shares of GreenMountain.com they receive in the
conversion. See "Description of Capital Stock--Registration Rights."

   We have been informed that, following our conversion from a limited
liability company to a corporation, but prior to the closing of this offering,
the shares of GreenMountain.com owned by each of Green Funding I and Green
Funding II will be distributed to the beneficial holders of the ownership
interests in those entities.

Other Transactions And Relationships

  Agreements With Sterling Software

   In February 1998, we entered into an agreement with Sterling Software, a
supplier of software products and services with expertise in network management
and automation. Under that agreement, Sterling Software provides us with
network management services and other information systems consulting services.
Under that agreement, we paid Sterling Software $828,611 for services provided
by it during 1998. We paid Sterling Software $576,857 during the first quarter
of 1999 in connection with that agreement.

   In addition, we entered into another agreement with Sterling Software in
early 1999 for the 1999 calendar year. This contract expanded the scope of
Sterling Software services to include programming and operational support for
data transmissions with all utility companies with which GreenMountain.com
interfaces, development of an enterprise database for our Information Network
and other software development projects for an approximate contract amount of
$4.4 million. As of March 31, 1999, we owed Sterling Software $771,117 under
that agreement, of which $391,365 was paid to it as of June 4, 1999.

   Each of the agreements with Sterling Software terminates upon the earliest
to occur of completion of the services by Sterling Software, the date 30 days
after Sterling Software's receipt of written notice by us terminating the
agreement and the date on which either party is declared in default if that
party has breached a material provision of the agreement and failed within 15
days after receipt of notice of the default to cure or commence curing the
breach.

   Sam Wyly and Evan Wyly are directors and stockholders of Sterling Software.
Each of the agreements with Sterling Software was negotiated on an arms' length
basis and GreenMountain.com believes that the terms of these agreements are
comparable to those that could have been obtained with an unrelated third
party.

                          DESCRIPTION OF CAPITAL STOCK

   Our certificate of incorporation provides that we are authorized to issue
150,000,000 shares of common stock, par value $0.01 per share, and, prior to
the closing of this offering, our certificate of incorporation will be amended
so that we will be authorized to issue 50,000,000 shares of preferred stock,
par value $0.01 per share. As of March 31, 1999, there were 25,546,500 shares
of common stock outstanding held of record by 91 stockholders, outstanding
options to purchase 5,987,229 shares of common stock and outstanding warrants
to purchase 11,907 shares of common stock. These amounts assume our conversion
from a limited liability company to a corporation and the related exchange of
each common unit of the limited liability company for three shares of common
stock of the corporation had occurred as of that date.

Common Stock

   Holders of common stock are entitled to one vote for each share held on all
matters submitted to a vote of stockholders and do not have cumulative voting
rights. Accordingly, holders of a majority of the shares of common stock
entitled to vote in any election of directors may elect all of the directors
standing for election. Holders of common stock are entitled to receive
proportionately any dividends that may be declared by our board of directors,
subject to any preferential dividend rights of outstanding preferred stock. In
the event of the liquidation, dissolution or winding up of GreenMountain.com,
holders of common stock would be entitled to receive proportionately any of our
assets remaining after the payment of liabilities and subject to the prior
rights of any outstanding preferred stock. Holders of common stock have no
preemptive, subscription, redemption or conversion rights. Our outstanding
shares of common stock are, and the shares offered by us in this offering will
be, when issued and paid for, fully paid and nonassessable.

Preferred Stock

   The board of directors will have the authority, within the limitations and
restrictions stated in our amended certificate of incorporation, to provide by
resolution for the issuance of shares of preferred stock, in one or more
classes or series, and to fix the rights, preferences, privileges and
restrictions for them, including dividend rights, conversion rights, voting
rights, terms of redemption, liquidation preferences and the number of shares
constituting any series and the designation of that series. The issuance of
preferred stock could adversely affect the voting and other rights of the
holders of common stock.

Registration Rights

   After the closing of this offering, the holders of 50.5% of the outstanding
shares of common stock will hold registration rights that will allow them to
"piggyback" the registration of their shares under the Securities Act on future
registrations of our securities. Accordingly, whenever we propose to register
any shares of our common stock under the Securities Act (other than
registrations on Forms S-4 or S-8), these stockholders have the right to
include their shares of common stock in that registration. However, the number
of shares that those stockholders may include in any registration will be
reduced if the underwriters for that offering advise us that the aggregate
number of shares should be reduced. We are generally obligated to bear all
expenses, other than underwriting discounts and sales commissions, of the
registration of all shares of common stock of those stockholders. The
registration rights require those stockholders to indemnify us in some
circumstances. Registration of any of the shares of common stock held by
holders of registration rights generally would result in those shares becoming
freely tradable without restriction under the Securities Act immediately
following their distribution in the manner described in the applicable
registration statement.

Provisions Of Our Certificate of Incorporation, Our Bylaws And Delaware Law

   Prior to the closing of this offering, our certificate of incorporation and
bylaws will be amended. Some provisions of our certificate of incorporation and
bylaws, as so amended, and Delaware law may have an anti-

                                       80

                                                                  Choose wisely.
<PAGE>

takeover effect and delay, defer or prevent a tender offer or takeover attempt
that a stockholder may consider in its best interest, including those attempts
that might result in a premium over the market price for the shares held by
stockholders.

  Classified Board Of Directors, Removal Of Directors And Filling Vacancies In
Directorships

   Our amended certificate of incorporation will provide that our board of
directors is divided into three classes of directors serving staggered three-
year terms. See "Management--Classified Board of Directors." In addition, our
amended certificate of incorporation will provide that directors may be removed
only for cause by the affirmative vote of the holders of at least 80% of our
voting securities entitled to vote. Under our amended certificate of
incorporation, any vacancy on our board of directors, including a vacancy
resulting from an enlargement of our board of directors, may be filled by the
vote of a majority of our directors then in office. The classification of our
board of directors and the limitations on the removal of directors and filling
of vacancies may deter a third party from seeking to remove incumbent directors
and simultaneously gaining control of the board of directors by filling the
vacancies created by such removal with its own nominees.

  Cumulative Voting

   Our amended certificate of incorporation will expressly deny stockholders
the right to cumulate votes in the election of directors. As a result, the
holders of a majority of the shares voted can elect all directors standing for
election.

  Stockholder Action And Special Meeting Of Stockholders

   Our amended certificate of incorporation will eliminate the ability of
stockholders to act by written consent in lieu of a meeting. It will also
provide that special meetings of the stockholders may only be called by our
Chairman, a Vice Chairman, by our Secretary within ten calendar days after
receipt of a written request of a majority of the total number of directors
(assuming no vacancies) or as otherwise may be provided in a preferred stock
designation and the business permitted to be conducted at any such meeting will
be limited to that brought before the meeting that is specified in the notice
of the meeting given by or at the direction of our Chairman, a Vice Chairman or
a majority of the total number of directors (assuming no vacancies) or that is
otherwise properly brought before the meeting by the presiding officer or by or
at the direction of a majority of the total number of directors (assuming no
vacancies).

  Advance Notice Requirements For Stockholder Proposals And Directors
Nominations

   Our amended bylaws will provide that stockholders seeking to bring business
before an annual meeting of stockholders or nominate candidates for election as
directors at an annual meeting of stockholders must provide timely notice in
writing. To be timely, a stockholder's notice must be delivered to or mailed
and received at our principal executive offices not less than 60 days nor more
than 90 days prior to the anniversary date of the date on which we first mail
our proxy materials for the prior year's annual meeting of stockholders, except
that if there was no annual meeting held during the prior year or if the annual
meeting is called for a date that is not within 30 days before or after that
anniversary, notice by the stockholder in order to be timely must be received
not later than the close of business on the tenth day following the date on
which public announcement was first made of the date of the annual meeting. Our
amended bylaws will also specify requirements as to the form and content of a
stockholder's notice. These provisions may preclude stockholders from bringing
matters before an annual meeting of stockholders or from making nominations for
directors at an annual meeting of stockholders.

  Authorized But Unissued Shares

   Authorized but unissued shares of common stock and preferred stock under our
amended certificate of incorporation will be available for future issuance
without stockholder approval. These additional shares may be used for a variety
of corporate purposes, including future public offerings to raise additional
capital,

                                       81

<PAGE>

corporate acquisitions and employee benefit plans. The existence of authorized
but unissued shares of common stock and preferred stock could render more
difficult or discourage an attempt to obtain control of us by means of a proxy
contest, tender offer, merger or otherwise.

  Supermajority Vote Requirements

   Delaware law provides generally that the affirmative vote of a majority of
the shares entitled to vote on any matter is required to amend a corporation's
certificate of incorporation or bylaws, unless a corporation's certificate of
incorporation or bylaws, as the case may be, requires a greater percentage. Our
amended certificate of incorporation and bylaws will require the affirmative
vote of the holders of at least 80% of our voting securities entitled to vote,
to amend, repeal or adopt any provision inconsistent with some provisions,
including those provisions relating to:

  .our classified board of directors;

  .directorship vacancies and removal of directors;

  .action by written consent of stockholders;

  .special meetings of stockholders; and

  .stockholder proposals and nominations of directors.

  Delaware Section 203

   We are subject to the provisions of Section 203 of the Delaware General
Corporation Law. Section 203 prohibits a publicly held Delaware corporation
from engaging in a "business combination" with an "interested stockholder" for
a period of three years after the person became an interested stockholder,
unless the interested stockholder attained that status with the approval of the
board of directors or the business combination is approved in a prescribed
manner. A "business combination" includes some mergers, asset sales and other
transactions resulting in a financial benefit to the interested stockholder.
Subject to some exceptions, an "interested stockholder" is a person who,
together with affiliates and associates, owns, or within the prior three years
did own, 15% or more of the corporation's voting stock.

Market Information

   Prior to this offering, there has been no public trading market for our
common stock. We have filed an application to include our common stock in the
Nasdaq National Market under the symbol "GMTN."

Transfer Agent

   Our registrar and transfer agent for our common stock is Harris Trust and
Savings Bank.

                                                                  Choose wisely.
<PAGE>

                        SHARES ELIGIBLE FOR FUTURE SALE

   Prior to this offering, there has been no public market for our common
stock. The market price of our common stock could drop due to sales of a large
number of shares of our common stock or the perception that such sales could
occur. These factors could also make it more difficult to raise funds through
future offerings of common stock.

   After this offering, 50,546,500 shares of common stock will be outstanding,
assuming the conversion of each common unit of the limited liability company
outstanding as of the date of this prospectus into shares of common stock. See
"Capitalization." Of these shares, the 25,000,000 shares sold in this offering
will be freely tradeable without restriction under the Securities Act except
for any shares purchased by "affiliates" of GreenMountain.com as defined in
Rule 144 under the Securities Act. The remaining 25,546,500 shares are
"restricted securities" within the meaning of Rule 144 under the Securities
Act. The restricted securities generally may not be sold unless they are
registered under the Securities Act or are sold pursuant to an exemption from
registration, such as the exemption provided by Rule 144 under the Securities
Act. If the underwriters exercise their over-allotment option in full, the
number of shares of common stock outstanding after this offering would increase
to 54,296,500 and, of those shares, 28,750,000 shares would be freely tradeable
and 25,546,500 would be restricted securities as described above.

   Our officers, directors and stockholders holding in the aggregate 25,464,000
outstanding shares of common stock have entered into lock-up agreements under
which they have agreed not to offer or sell any shares of common stock for a
period of 180 days after the date of this prospectus without the prior written
consent of Prudential Securities, on behalf of the underwriters. See
"Underwriting." Prudential Securities may, at any time and without notice,
waive any of the terms of these lock-up agreements specified in the
underwriting agreement. Following the lock-up period, these shares will not be
eligible for sale in the public market without registration under the
Securities Act unless such sales meet the applicable conditions and
restrictions of Rule 144 as described below.

   In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this prospectus, any person (or persons whose shares are
aggregated), including an affiliate, who has beneficially owned shares for a
period of at least one year is entitled to sell, within any three-month period,
a number of shares that does not exceed the greater of:

  (1) 1% of the then-outstanding shares of common stock, and
  (2) the average weekly trading volume in the common stock during the four
      calendar weeks immediately preceding the date on which the notice of
      such sale on Form 144 is filed with the Securities and Exchange
      Commission.

   Sales under Rule 144 are also subject to provisions relating to notice and
manner of sale and the availability of current public information about us. In
addition, a person (or persons whose shares are aggregated) who has not been an
affiliate of us at any time during the 90 days immediately preceding a sale,
and who has beneficially owned the shares for at least two years, would be
entitled to sell such shares under Rule 144(k) without regard to the volume
limitation and other conditions described above. While the foregoing discussion
is intended to summarize the material provisions of Rule 144, it may not
describe all of the applicable provisions of Rule 144, and, accordingly, you
are encouraged to consult the full text of that Rule.

   In addition, our employees, directors, officers, advisors or consultants who
were issued shares pursuant to a written compensatory plan or contract may be
entitled to rely on the resale provisions of Rule 701, which permits non-
affiliates to sell their Rule 701 shares without having to comply with the
public information, holding period, volume limitation or notice provisions of
Rule 144, and permits affiliates to sell their Rule 701 shares without having
to comply with Rule 144's holding period restrictions, in each case commencing
90 days after the date of this prospectus.

   As soon as practicable following the closing of this offering, we intend to
file one or more registration statements under the Securities Act to register
12,636,625 shares of common stock issuable upon the exercise of outstanding
stock options or reserved for issuance under our 1999 Stock Option Plan and
150,000 shares of common stock reserved for issuance under our 1999 Director
Stock Award Plan. See "Management--Director Compensation" and "--Stock Option
Agreements and Plans." After the effective date of such registration
statements, when issued these shares will be available for sale in the open
market subject to the lock-up agreements described above and, for our
affiliates, to the conditions and restrictions of Rule 144.

   The underwriters may sell more shares than the total number of shares
offered on the cover page of this prospectus and they have, for a period of 30
days from the date of this prospectus, an over-allotment option to purchase up
to 3,750,000 additional shares from us. If any of the additional shares are
purchased, the underwriters will severally purchase the additional shares in
the same proportion as set forth above.

   The representative of the underwriters has advised us that the shares will
be offered to the public at the public offering price set forth on the cover
page of this prospectus. The underwriters may allow to selected dealers a
commission not in excess of $  per share and those dealers may reallow a
commission not in excess of $  per share to other dealers. After the shares are
released for sale to the public, the public offering price, the concession to
selected dealers and the reallowance to other dealers may be changed by the
underwriters. The representative has informed us that the underwriters do not
intend to sell shares to any investor who has granted them discretionary
authority.

   We have engaged Prudential Securities to act as our financial advisor in
connection with various business and strategic matters, in consideration for a
fee of 0.625% of the gross proceeds received by GreenMountain.com in this
offering.

   We have agreed to pay to the underwriters the following fees, assuming both
no exercise and full exercise of the underwriters' over-allotment option to
purchase additional shares:

   Our officers, directors and stockholders holding in the aggregate 25,464,000
outstanding shares of common stock have entered into lock-up agreements
pursuant to which we and they have agreed not to offer or sell any shares of
common stock or securities convertible into or exchangeable or exercisable for
shares of common stock for a period of 180 days from the date of this
prospectus, subject to limited exceptions for option grants and exercises,
without the prior consent of Prudential Securities. Prudential Securities may,
at any time and without notice, waive the terms of these lock-up agreements as
specified in the underwriting agreement.

   Prior to this offering, there has been no public market for our common
stock. The public offering price, negotiated between the representative and us,
is based upon factors such as our financial and operating history and
conditions, our prospects, the prospects of our industry and prevailing market
conditions.

   Prudential Securities, representing the underwriters, may engage in the
following activities in accordance with applicable securities rules:

  .Over-allotments involving sales in excess of the offering size, creating a
   short position. Prudential Securities may elect to reduce this short
   position by exercising some or all of the over-allotment option.

  .Stabilizing and short covering: stabilizing bids to purchase the shares
   are permitted if they do not exceed a specified maximum price. After the
   distribution of shares has been completed, short covering purchases in the
   open market may also reduce the short position. These activities may cause
   the price of the shares to be higher than would otherwise exist in the
   open market.

  .Penalty bids permit the representatives to reclaim commissions from a
   syndicate member for the shares purchased in the stabilizing or short
   covering transactions.

   Such activities, which may be commenced and discontinued at any time, may be
effected on the Nasdaq National Market, in the over-the-counter market or
otherwise.

   We have asked the underwriters to reserve shares for sale at the same
offering price directly to our customers, employees, officers, directors and
other business affiliates or related third parties. The number of shares
available for sale to the general public in the offering will be reduced to the
extent such persons purchase the reserved shares.

                                 LEGAL MATTERS

   The validity of the common stock under Delaware law will be passed upon for
us by Jones, Day, Reavis & Pogue, Dallas, Texas. Additional legal matters in
connection with the offering will be passed upon for the underwriters by Cooley
Godward LLP, San Diego, California.

/s/ Arthur Andersen LLP

Boston, Massachusetts

June 4, 1999

                    Report of Independent Public Accountants

To the Stockholders of
GreenMountain.com Company:

   We have audited the accompanying balance sheets of GreenMountain.com Company
(a Delaware corporation) as of December 31, 1997 and 1998, and related
statements of operations, stockholders' equity and cash flows for the period
from inception (February 26, 1997) through December 31, 1997 and for the year
ended December 31, 1998. These financial statements are the responsibility of
the Company's management. Our responsibility is to express an opinion on these
financial statements based on our audit.

   We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audit provides a reasonable basis
for our opinion.

   In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of GreenMountain.com Company
as of December 31, 1997 and 1998, and the related statements of operations,
stockholders' equity and cash flows for the period from inception (February 26,
1997) through December 31, 1997 and for the year ended December 31, 1998, in
conformity with generally accepted accounting principles.

                         Notes to Financial Statements
                   (Information at March 31, 1999 and for the
            Three Months Ended March 31, 1998 and 1999 is Unaudited)

(1) Organization and Business

   GreenMountain.com Company, formerly known as Green Mountain Energy Resources
L.L.C., is a Delaware corporation, originally formed as a limited liability
company. As further discussed in Note 12, Green Mountain Energy Resources
L.L.C. reorganized into a corporation in 1999.

   On August 6, 1997, a subsidiary of Green Mountain Power Corporation and
Green Funding I, L.L.C., an investment vehicle controlled by the Wyly family,
negotiated and entered into a limited liability company agreement relating to
the formation of Green Mountain Energy Resources L.L.C. Green Mountain Energy
Resources L.L.C. was formed to become a national retail marketer of electricity
produced from renewable and other environmentally preferable sources to
residential customers. Under the limited liability agreement:

 .  A subsidiary of Green Mountain Power Corporation contributed certain
    service marks, research performed by Green Mountain Power Corporation
    prior to formation of the limited liability company related to evaluating
    the viability of a nationally-marketed, premium priced green electricity
    product, including marketing studies and analyses, and its rights under
    agreements with several third-party service providers, in exchange for a
    33% equity interest, after the effect of the return of capital discussed
    below, in the limited liability company;

 .  Green Funding I contributed $8,000,000 and committed to contribute an
    additional $22,000,000 over time, in exchange for a 67% equity interest in
    the limited liability company; and

 .  Immediately following the initial contribution by Green Funding I, the
    subsidiary of Green Mountain Power Corporation received a distribution
    from the limited liability company of $4,000,000, representing
    reimbursement for the cost of market studies and analyses and other
    development costs incurred by Green Mountain Power Corporation prior to
    formation of the limited liability company based on a provision in the
    limited liability company agreement.

   The limited liability company agreement also contained provisions relating
to the allocation of profits and losses, the management of the limited
liability company and restrictions on transfer and registration rights.

   Green Mountain Energy Resources L.L.C. began active operations on August 6,
1997 under the terms of an operating agreement, dated August 6, 1997. On
September 29, 1997, Green Funding I committed an additional $10,000,000 to the
limited liability company. Green Mountain Power Corporation elected not to
contribute additional equity, resulting in an increase in Green Funding I's
equity interest to 73%. On November 20, 1998, Green Funding I committed an
additional $20,000,000 to the limited liability company. Green Mountain Power
Corporation again elected not to contribute additional equity, resulting in an
increase in Green Funding I's equity interest to 99%.

   On December 23, 1998, Green Mountain Energy Resources L.L.C. negotiated and
entered into an agreement with Green Mountain Power Corporation to buy back its
equity interests in the limited liability company and to obtain a non-compete
agreement, certain rights to the Green Mountain name and certain mutual
releases for $1,000,000. This agreement enabled the limited liability company
to eliminate its ties to a traditional, regulated utility that had elected not
to contribute additional equity to the limited liability company. In addition,
this agreement contained favorable provisions relating to non-competition and
the use of the Green Mountain name. The payments were made in two installments
on January 4, 1999 and February 16, 1999. The limited liability company
allocated $647,400 to the repurchased equity interest ($3.33 a share) and
$352,600 to the non-compete agreement, certain rights to the Green Mountain
name and certain mutual releases obtained. This allocation was based on the
management committee's determination of the fair value of the equity interest
and other intangible assets obtained given an anticipated offering in early
January and February of 1999 at $3.33 per share.

                Notes to Financial Statements--(Continued)

                (Information at March 31, 1998 and for the

         Three Months Ended March 31, 1998 and 1999 is Unaudited)


   The limited liability company losses for the period and year ended
December 31, 1997 and 1998 were allocated 100% to Green Funding I under the
operating agreement. Accordingly, the Company has no tax loss carry forwards
related to losses during those periods. The operating agreement was amended
January 4, 1999 to allocate losses, first to members other than Green Funding
I, to the extent of those members' capital contributions and, thereafter, to
members, including Green Funding I, in proportion to their respective ownership
interests.

   GreenMountain.com has generated approximately $1.5 million in residential
electric revenue sales in California during 1998 and $4.1 million in California
and Pennsylvania during the three months ended March 31, 1999. The retail
energy market is at an early stage of development, as only a few states have
deregulated sales of electricity on a statewide basis as of December 1998.
GreenMountain.com began serving customers in Pennsylvania on January 1, 1999.
As of December 31, 1998 and March 31, 1999, GreenMountain.com had accumulated
deficits of $59,901,079 and $79,695,769, respectively. GreenMountain.com is
seeking additional investors, through an initial public offering, to fund its
planned expansion of its existing electricity business into new deregulated
markets and to broaden its green product offerings. The implementation of
GreenMountain.com's business plan is dependent on this offering. There can be
no assurance that such additional financing will be available. If
GreenMountain.com is unable to obtain financing through an initial public
offering, GreenMountain.com will curtail its current growth plans and
GreenMountain.com believes its existing cash resources, together with financing
available under an agreement with Green Funding I, in an amount up to $22
million, will be sufficient to fund its operations at least through 1999. Any
advances under the agreement will bear interest at 6% per annum. The agreement
provides that accrued and unpaid interest will be added to the principal on
each June 30 and December 31. Principal, together with accrued and unpaid
interest, will be payable on April 23, 2001. This agreement terminates upon an
initial public offering and any advances made under the agreement become due
and payable. As of June 4, 1999, no amounts were outstanding under this
agreement.

(2) Summary of Significant Accounting Policies

 (a) Basis of Presentation

   Financial statements of a development stage company are prepared and
presented in the same manner as those of operating enterprises.
GreenMountain.com was considered a development stage company as of and for the
period from inception through December 31, 1997.

 (b) Reclassifications

   Certain prior year amounts have been reclassified to be consistent with the
current presentation.

 (c) Restricted Cash

   Certain of GreenMountain.com's power supply vendors and state regulators
require letters of credit to ensure fulfillment of the Company's commitments.
Associated amounts have been classified as restricted cash on the accompanying
balance sheet.

 (d) Organization Costs

   In April 1998, the American Institute of Certified Public Accountants
(AICPA) issued Statement of Position (SOP) No. 98-5, Reporting on the Costs of
Start-Up Activities, which requires that all start-up costs, including
organization costs, should be expensed as incurred. The new standard is
effective for fiscal years

                           GreenMountain.com Company

                   Notes to Financial Statements--(Continued)
                   (Information at March 31, 1999 and for the
            Three Months Ended March 31, 1998 and 1999 is Unaudited)

beginning after December 15, 1998, with early application encouraged. In the
fourth quarter of 1998 GreenMountain.com wrote off the remaining unamortized
balance of organization costs, amounting to $269,892, or $0.04 per share, in
accordance with the new pronouncement. This amount is included in development
and transaction costs in the accompanying Statements of Operations.

 (e) Property and Equipment

   Property and equipment are stated at cost. GreenMountain.com provides for
depreciation on property and equipment on the straight-line basis over their
estimated useful lives as follows:

<TABLE>
      <S>                                                             <C>
      Computer hardware..............................................   2 years
      Computer software.............................................. 1-5 years
      Furniture and fixtures......................................... 5-7 years
</TABLE>

 (f) Other Assets

   Other assets include a non-competition agreement being amortized over seven
years and deferred costs related to GreenMountain.com's planned initial public
offering. These deferred costs will be reclassified to additional paid-in
capital upon the closing of the equity offering.

 (g) Federal Income Taxes

   Federal income taxes have not been recorded in the accompanying financial
statements because such taxes, if any, were the responsibility of the
stockholders prior to the reorganization described in Note 12.

 (h) Impairment of Long-Lived Assets

   GreenMountain.com follows SFAS No. 121, Accounting for Long-Lived Assets and
for Long-Lived Assets To Be Disposed Of. SFAS No. 121 requires that long-lived
assets be reviewed for impairment by comparing the fair value of the assets
with their carrying amount. Any write-downs are to be treated as permanent
reductions in the carrying amount of the assets. Accordingly, GreenMountain.com
evaluates the possible impairment of long-lived assets at each reporting period
based on the undiscounted projected cash flows of the related asset. Should
there be an impairment, the cash flow estimates that will be used will contain
management's best estimates, using appropriate and customary assumptions and
projections at the time. To date GreenMountain.com does not believe that an
impairment exists.

 (i) Use of Estimates in the Preparation of Financial Statements

   The presentation of the financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosures of contingent assets and liabilities as of the date of the
financial statements and the reported amounts of income and expenses during the
reporting period. Operating results in the future could vary from the amounts
derived from management's estimates and assumptions.

 (j) Fair Value of Financial Instruments

   GreenMountain.com's financial instruments consist primarily of cash,
accounts receivable, unbilled accounts receivable and accounts payable. The
carrying amounts of these financial instruments as of December 31, 1997 and
1998 and March 31, 1999 approximate their fair values due to their short-term
nature.

                   Notes to Financial Statements--(Continued)
                   (Information at March 31, 1999 and for the
            Three Months Ended March 31, 1998 and 1999 is Unaudited)


 (k) Revenue Recognition and Unbilled Accounts Receivable

   Customers are billed for their use of electricity on a cycle basis
throughout the month. To reflect revenues in the proper period, the estimated
amount of unbilled sales revenue related to customer electricity usage is
recorded each month.

 (l) Earnings per Share

   The dilutive effect of potential common shares, consisting of outstanding
stock options and warrants is determined using the treasury method in
accordance with SFAS No. 128, Earnings per Share, which established standards
for computing and presenting earnings per share and which applies to entities
with publicly held common stock or potential common stock. In accordance with
SEC Staff Accounting Bulletin (SAB) No. 98, GreenMountain.com has determined
that there were no nominal issuances of common stock or potential common stock
in the period prior to GreenMountain.com's planned initial public offering.
Diluted weighted average shares outstanding for 1997 and 1998 exclude the
potential common shares from warrants and stock options because to do so would
have been antidilutive. The potential common shares excluded as of December 31,
1997 and 1998, and March 31, 1998 and 1999 related to outstanding warrants and
stock options were 111,267, 103,527, 112,077 and 5,999,136 respectively.

 (m) Unaudited Interim Information

   The financial information as of March 31, 1999 and for the three months
ended March 31, 1998 and 1999 is unaudited. In the opinion of management, such
information contains all adjustments, consisting only of normal recurring
accruals, necessary for a fair presentation of the results of such period.

 (n) Employee Benefit Plan

   GreenMountain.com has a defined contribution plan in which GreenMountain.com
contributes 2% of each employee's base salary up to the social security wage
base and 4% of such base above the social security wage base up to $160,000.
Additionally, GreenMountain.com matches 50% of each employee's contribution up
to the employee's first 6% contribution. Both GreenMountain.com and employee
contributions vest immediately. The charges included in the accompanying
Statements of Operations under this plan for the year ended December 31, 1998
and the period from inception through December 31, 1997 are $153,719 and
$20,821, respectively, and for the three months ended March 31, 1999 and 1998
are $46,354 and $34,084, respectively.

 (o) Advertising Costs

   Advertising costs are expensed as incurred as such efforts historically have
not met the direct-response criteria required for capitalization.
GreenMountain.com advertising to date have related to (1) building brand
awareness, including traditional media advertising such as television, radio,
print and billboards and sponsorship of special events and promotions and (2)
direct marketing, including direct mail, affinity programs, internet and
inbound and outbound telemarketing. Total advertising costs for the period from
inception, February 26, 1997 through December 31, 1997, for the year ended
December 31, 1998 and for the three months ended March 31, 1998 and 1999, were
$4.3 million, $33.0 million, $4.1 million and $12.4 million, respectively. As
new advertising agreements are entered into, such as the Yahoo! Inc. agreement
which commences in May 1999, such costs could have long-term value and result
in capitalization and amortization over the period benefited. See Note (5)(d)-
Commitments and Contingencies for a discussion of GreenMountain.com's Marketing
Services Agreement and Note (5)(f) for a discussion of its contract with Yahoo!

 (c) Warrants

   During 1997, GreenMountain.com issued warrants to its consultants and
advisors for 11,907 shares at fair market value. The warrants vested
immediately and expire on the fifth anniversary date of the grant.

 (d) Stock-Based Compensation

   In October 1995, the FASB issued SFAS No. 123, Accounting for Stock-Based
Compensation. SFAS No. 123 requires the measurement of the fair value of stock
options to be included in the statements of income or disclosed in the notes to
financial statements. GreenMountain.com has determined that it will continue to
account for stock-based compensation for employees under Accounting Principles
Board Opinion No. 25, Accounting for Stock Issued to Employees, and elect the
disclosure-only alternative under SFAS No. 123.

   The fair value of each option grant is estimated on the date of grant using
the Black-Scholes option pricing model with the following assumptions used for
grants during the applicable period:

(5) Commitments and Contingencies

 (a) Power Supply Agreements

   For the Pennsylvania market, GreenMountain.com has entered into three
agreements with major wholesale suppliers for electricity supply to serve the
requirements of GreenMountain.com's customers. Under all of the agreements, the
suppliers will provide electricity for a period of one year that matches the
aggregate customer requirements that are assigned to them. For two of the
agreements, either GreenMountain.com or the supplier can discontinue the
assignment of additional customers upon three months' notice. The wholesale
price is fixed for the term of the agreements.

   For the California market, GreenMountain.com has negotiated requirements
contracts with two suppliers to supply its current product offerings in the
California market. Under both agreements, the wholesale price is based on a
fixed price spread related to the PX price of power (refers to the per kwh
wholesale electricity price in California, as determined by the California
Power Exchange) with one agreement providing for a surcharge on the Wind for
the FutureSM wind power product. One supplier provides electricity for a period
of one year for each of GreenMountain.com's customers assigned to it and either
party may discontinue the assignment of

additional customers to the agreement upon three months' notice. The other
supplier provides electricity for one and three year service periods, depending
on the product being served, and can be assigned additional customers through

   GreenMountain.com's contracts with four suppliers provide for separate
letters of credit or equivalent financial assurances to satisfy credit
requirements. The amounts of the letters of credit range from fifteen days' to
two months' of receivables based on GreenMountain.com's load forecast. In
addition, GreenMountain.com has delivered to one supplier irrevocable letters
of credit in connection with the supplier's purchase and installation of three
wind power turbines. GreenMountain.com also delivered letters of credit to
regulators securing its performance as an energy service provider. Total supply
and regulatory letters of credit outstanding at December 31, 1998 and March 31,

the other party. The contract states that prior to the end of the Initial Term
and each renewal term, the parties may mutually agree to extend this agreement
for one additional contract year. GreenMountain.com has agreed to pay monthly
service charges for call center and billing services, additional resource
charges and cost of living adjustment to compensate en . able for the volumes
processed and all of the resources used in providing the services. The monthly
charges are variable and are based on the number of billable accounts
maintained each month. GreenMountain.com has agreed to pay minimum monthly
service charges for call center service and billing services in the amount of
$112,500 based on a customer billable unit baseline of 50,000 customers.

(8) Accounts Receivable

   As of December 31, 1998 and March 31, 1999, GreenMountain.com is owed
$137,970 and $223,805, respectively, from the California Energy Commission
related to renewable energy credits provided to GreenMountain.com for selling
renewable energy to customers. GreenMountain.com expects to collect these
amounts in 1999.

(9) Short-Term Borrowings

   GreenMountain.com borrowed a total of $10,000,000 in September and October
1998 from a financing company, which was subsequently repaid with a portion of
Green Funding I's additional $20,000,000 commitment. The interest due on such
borrowings was paid in early 1999. This loan, which bore interest at a rate of
10% per annum, was made by Security Capital, Ltd. Several entities, whose stock
is owned by irrevocable trusts of which certain members of the Wyly family are
beneficiaries, provided credit enhancement for the loan.

(10) Recent Accounting Pronouncements

   The FASB recently issued SFAS No. 130, Reporting Comprehensive Income. SFAS
No. 130 establishes standards for reporting and displaying comprehensive income
and its components in financial statements. Comprehensive income, as defined,
includes all changes to equity (net assets) during a period from non-owner
sources. SFAS No. 130 is effective for financial statements for fiscal years
beginning after December 15, 1997. To date, GreenMountain.com has not had any
transactions that are required to be reported in comprehensive income.

   The FASB recently issued SFAS No. 131, Disclosure About Segments of an
Enterprise and Related Information. SFAS No. 131 establishes standards for the
way public business enterprises are to report information about operating
segments in annual financial statements and requires those enterprises to
report selected information about operating segments in interim financial
reports. SFAS No. 131 is effective for financial statements for fiscal years
beginning after December 15, 1997. GreenMountain.com has determined that it
does not have any separately reportable business segments.

   In June 1998, the FASB issued SFAS No. 133, Accounting for Derivative
Instruments and Hedging Activities. This statement establishes accounting and
reporting standards requiring that every derivative instrument (including
certain derivative instruments embedded in other contracts) be recorded in the
balance sheet as either an asset or liability measured at its fair value. The
statement requires that changes in the derivative's fair value be recognized
currently in earnings unless specific hedge accounting criteria are met.
Special accounting for qualifying hedges allows a derivative's gains and losses
to offset related results on the hedged item in the income statement, and
requires that a company must formally document, designate, and assess the
effectiveness of transactions that receive hedge accounting. SFAS No. 133 is
effective for fiscal years beginning after June 15, 1999. A company may also
implement the statement as of the beginning of any fiscal quarter after
issuance (that is, fiscal quarters beginning June 16, 1998 and thereafter).
SFAS No. 133 cannot be applied retroactively. SFAS No. 133 must be applied to
(a) derivative instruments and (b) certain derivative instruments embedded in
hybrid contracts that were issued, acquired, or substantively modified after
December 31, 1997 (and, at the company's election, before January 1, 1998).
This statement could increase volatility in earnings and other comprehensive
income for companies with applicable contracts. GreenMountain.com does not have
any derivative instruments at this time; however, such instruments may be
embedded in future electricity contracts.

                   (Information at March 31, 1999 and for the
            Three Months Ended March 31, 1998 and 1999 is Unaudited)


   The AICPA issued SOP No. 98-1, Software for Internal Use, which provides
guidance on accounting for the cost of computer software developed or obtained
for internal use. SOP No. 98-1 is effective for financial statements for fiscal
years beginning after December 15, 1998. The adoption of SOP No. 98-1 did not
have a material impact on GreenMountain.com's financial statements.
GreenMountain.com anticipates that in the second quarter of 1999 it will begin
capitalizing certain costs in accordance with SOP No. 98-1 associated with
projects that enter the development stage, including its web site development
project.

(11) Subsequent Event--Private Placement Offerings

   During 1999, GreenMountain.com completed two private placement offerings.
The first offering, completed in early January and early February 1999, was for
$10,000,000 from a sale of 3,000,000 shares to GreenMountain.com's employees
and certain consultants for $3.33 per share. Net proceeds included $4,891,750
of cash and $5,108,250 of promissory notes from employees and certain
consultants. GreenMountain.com recognized compensation expense of $2,072,300 in
connection with the issuance of shares. The second offering, completed in mid-
February 1999, resulted in net proceeds of $30,310,000 from a sale of 4,546,500
shares to investors for $6.67 per share. As a result of purchases during the
second offering, Maverick Capital became the beneficial owner of 2,250,000
shares for an aggregate purchase price of $15.0 million. Evan Wyly, a Vice
Chairman and a Director of GreenMountain.com, is a Managing Partner and H. Lee
S. Hobson, a GreenMountain.com Director, is a Partner of Maverick Capital. In
addition, Green Funding II, L.L.C., an investment vehicle controlled by the
Wyly family, acquired directly 1,500,000 shares for an aggregate purchase price
of $10.0 million.

(12) Subsequent Event--Reorganization

   In 1999, GreenMountain.com merged into a newly formed Delaware corporation,
which (i) was the entity surviving the merger, succeeding to all rights,
properties and obligations of GreenMountain.com; (ii) is named
GreenMountain.com Company; and (iii) is taxable as a corporation. In connection
with the conversion, the limited liability company agreement will terminate,
except for certain covenants that, by their terms, require performance after
the termination of such agreement and each member will receive three shares of
GreenMountain.com common stock in exchange for each of its common units in the
limited liability company (subject to the payment of cash in lieu of fractional
shares). Additionally, any undistributed tax losses at the date of
reorganization will be reclassified against additional paid in capital. All
outstanding options and warrants exercisable for common units in the limited
liability company will, in effect, be converted into options or warrants
exercisable for GreenMountain.com common stock. The common stock information in
the financial statements and notes has been restated as if the common units
were converted to common shares.

Item 14. Indemnification of Directors and Officers.

Limitation Of Liability And Indemnification Matters

   Prior to the closing of this offering, the Registrant's certificate of
incorporation and bylaws will be amended. The Registrant's amended certificate
of incorporation will limit the liability of the Registrant's directors to the
maximum extent permitted by Delaware law. Delaware law provides that a director
of a corporation will not be personally liable for monetary damages for breach
of that individual's fiduciary duties as a director except for liability for
(1) a breach of the director's duty of loyalty to the corporation or its
stockholders, (2) any act or omission not in good faith or that involves
intentional misconduct or a knowing violation of the law, (3) unlawful payments
of dividends or unlawful stock repurchases or redemptions, or (4) any
transaction from which the director derived an improper personal benefit.

   This limitation of liability does not apply to liabilities arising under
federal securities laws and does not affect the availability of equitable
remedies such as injunctive relief or recission.

   Section 145 of the Delaware General Corporation Law provides that a
corporation may indemnify directors and officers, as well as other employees
and individuals, against attorneys fees and other expenses, judgments, fines
and amounts paid in settlement actually and reasonably incurred by such person
in connection with any threatened, pending or completed actions, suits or
proceedings in which such person was or is a party or is threatened to be made
a party by reason of such person being or having been a director, officer,
employee or agent of the corporation. The Delaware General Corporation Law
provides that Section 145 is not exclusive of other rights to which those
seeking indemnification may be entitled under any bylaw, agreement, vote of
stockholders or disinterested directors or otherwise.

   The Registrant's amended certificate of incorporation and amended bylaws
will provide that the Registrant is required to indemnify its directors and
officers to the maximum extent permitted by law. The Registrant's amended
bylaws will also require the Registrant to advance expenses incurred by an
officer or director in connection with the defense of any action or proceeding
arising out of that party's status or service as a director or officer of the
Registrant or as a director, officer, employer or agent of another corporation,
partnership, joint venture, trust, employee benefit plan or other enterprise,
if serving as such at the Registrant's request. The Registrant's amended bylaws
will also permit the Registrant to secure insurance on behalf of any director
or officer for any liability arising out of his or her actions in a
representative capacity.


                                      II-1
<PAGE>

   The Registrant intends to enter into indemnification agreements with its
directors and some of its officers containing provisions that (1) indemnify, to
the maximum extent permitted by Delaware law, those directors and officers
against liabilities that may arise by reason of their status or service as
directors or officers except liabilities arising from willful misconduct of a
culpable nature, (2) to advance their expenses incurred as a result of any
proceeding against them as to which they could be indemnified, and (3) to
obtain directors' and officers' liability insurance if maintained for other
directors or officers.

   The Registrant's predecessor limited liability company currently has
liability insurance for its management committee members and officers and the
Registrant intends to obtain directors' and officers' liability insurance for
its directors and officers.

   Reference is also made to the Underwriting Agreement to be filed as Exhibit
1.1 to the Registration Statement for information concerning the underwriters'
obligation to indemnify the Registrant and its officers and directors in
certain circumstances.

Item 15. Recent Sales of Unregistered Securities.

   Since its formation on February 26, 1997, the limited liability company (the
"LLC") predecessor to the Registrant has issued and sold the following
securities:

     (1) In August 1997, the LLC issued and sold membership interests
  representing 67% of the LLC to Green Funding I, L.L.C. in exchange for $8.0
  million in cash and a commitment to contribute an additional $22.0 million
  in cash over time and membership interests representing 33% to Green
  Mountain Resources, Inc., a subsidiary of Green Mountain Power Corporation,
  in exchange for a contribution of property. The issuance of these
  membership interests was exempt from registration under Section 4(2) of the
  Securities Act of 1933, as amended (the "Act").

     (2) In August 1997, the LLC issued warrants to purchase membership
  interests to its consultants and advisors in exchange for services
  performed by such consultants and advisors. The issuance of these warrants
  was exempt from registration under Section 4(2) of the Act. These warrants
  are currently exercisable to purchase 3,969 common units of the LLC at an
  exercise price of $226.76 per unit.

     (3) In September 1997, the LLC issued and sold additional membership
  interests to Green Funding I, L.L.C. in exchange for $10.0 million in cash,
  increasing Green Funding I, L.L.C.'s ownership interest to approximately
  73% of the LLC. The issuance of these membership interests was exempt from
  registration under Section 4(2) of the Act.

     (4) In November 1998, the LLC issued and sold additional membership
  interests to Green Funding I, L.L.C., in exchange for $20.0 million in
  cash, increasing Green Funding I, L.L.C.'s ownership interest to
  approximately 99% of the LLC. The issuance of these membership interests
  was exempt from registration under Section 4(2) of the Act.

     (5) In early January and early February 1999, membership interests in
  the LLC were unitized and the LLC issued and sold 47,750 common units in
  the LLC to 34 of its employees in a private offering under a compensatory
  plan, the Employee Unit Purchase Plan, in exchange for an aggregate of
  $477,500, of which $250,500 was paid in cash and $227,000 was paid using
  promissory notes payable to the LLC and secured by the acquired units as
  permitted under the Employee Unit Purchase Plan. The issuance of these
  common units was exempt from registration under Rule 701 promulgated by the
  Securities and Exchange Commission (the "Commission") under Section 3(b) of
  the Act.

     (6) In early January and early February 1999, the LLC issued and sold
  952,250 common units in the LLC in a private offering to 28 individuals,
  each of whom qualified as an accredited investor as defined in Rule 501(a).
  Sixteen of these individuals acquired 908,250 common units for an aggregate
  of $9,082,500, of which $4,201,250 was paid in cash and $4,881,250 was paid
  using promissory notes payable to the LLC and secured by the acquired units
  as permitted under the Employee Unit Purchase

                                      II-2
<PAGE>

  Plan. Twelve of these individuals were consultants or advisors who acquired
  44,000 common units for an aggregate of $440,000 in cash. The issuance of
  these common units was exempt from registration under Section 4(2) of the
  Act and was made in compliance with Rule 506 under the Act.

     (7) In February 1999, the LLC issued and sold 1,515,500 common units in
  the LLC in a private offering to 28 individuals and entities in exchange
  for an aggregate of $30,310,000 in cash. Each individual and entity
  qualified as an accredited investor under Rule 501(a). The issuance of
  these common units was exempt from registration under Section 4(2) of the
  Act and was made in compliance with Rule 506 under the Act.

   All sales were made without general solicitation or general advertising.
Each purchaser represented that such purchaser was acquiring the interest for
investment purposes.

   Prior to the closing of this offering, the LLC will be merged into the
Registrant and each common unit in the LLC will be exchanged for three shares
of Registrant's common stock. In addition, all outstanding options and warrants
exercisable for common units in the LLC will, in effect, be converted into
options or warrants exercisable for the Registrant's common stock.

    (b) Financial Statement Schedules

    Report of Independent Public Accountants

    Schedule II -- Reserves for the Period from Inception (February 26,
    1997) through December 31, 1997

    Schedule II -- Reserves for the Year ended December 31, 1998

   Schedules not listed above have been omitted because the information
required to be set forth therein is not applicable or is shown in the financial
statements or notes thereto.

Item 17. Undertakings.

   Insofar as indemnification for liabilities arising under the Act may be
permitted to directors, officers and controlling persons of the Registrant
pursuant to the foregoing provisions, or otherwise, the Registrant has been
advised that, in the opinion of the Securities and Exchange Commission, such
indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the Registrant of expenses incurred
or paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question of whether such indemnification by it is
against public policy as expressed in the Act and will be governed by the final
adjudication of such issue.

   The undersigned Registrant hereby undertakes to provide to the Underwriters
at the closing specified in the Underwriting Agreement certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.

   The undersigned Registrant hereby undertakes that:

      (1) For purposes of determining any liability under the Act, the
  information omitted from the form of prospectus filed as part of this
  registration statement in reliance upon Rule 430A and contained in a form
  of prospectus filed by the registrant pursuant to 424(b)(1) or (4), or
  497(h) under the Act shall be deemed to be part of this registration
  statement as of the time it was declared effective.

      (2) For the purpose of determining any liability under the Act, each
  post-effective amendment that contains a form of prospectus shall be deemed
  to be a new registration statement relating to the securities offered
  therein, and the offering of such securities at that time shall be deemed
  to be the initial bona fide offering thereof.

/s/ Arthur Andersen LLP

Boston, Massachusetts

June 4, 1999

                    Report of Independent Public Accountants

To the Stockholders of
 GreenMountain.com Company:

   We have audited, in accordance with generally accepted auditing standards,
the financial statements of GreenMountain.com Company included in this
registration statement and have issued our report thereon. Our audit was made
for the purpose of forming an opinion on the basic financial statements taken
as a whole. The schedules listed in the accompanying index are the
responsibility of the Company's management and are presented for purposes of
complying with the Securities and Exchange Commission's rules and are not part
of the basic financial statements. These schedules have been subjected to the
auditing procedures applied in the audit of the basic financial statements and,
in our opinion, fairly state in all material respects the financial data
required to be set forth therein in relation to the basic financial statements
taken as a whole.

declared by the Commission to be effective under the Act, an amendment to such
registration statement, including a form of prospectus, a copy of which
amendment has been furnished to and approved by the Representatives prior to the
execution of this Agreement. The Company may also file a related registration

purpose of registering certain additional Securities, which registration shall
be effective upon filing with the Commission. As used in this Agreement, the
term "Original Registration Statement" means the registration statement
initially filed relating to the Securities, as amended at the time when it was
or is declared effective, including all financial schedules and exhibits thereto
and including any information omitted therefrom pursuant to Rule 430A under the
Act and included in the Prospectus (as hereinafter defined); the term "Rule
462(b) Registration Statement" means any registration statement filed with the
Commission pursuant to Rule 462(b) under the Act (including the Original
Registration Statement and any Preliminary Prospectus or Prospectus incorporated
in such registration statement at the time such registration statement becomes
effective pursuant to Rule 462(b)); the term "Registration Statement" means the
Original Registration Statement together with any Rule 462(b) Registration
Statement; the term "Preliminary Prospectus" means each prospectus subject to
completion included in the registration statement initially filed relating to
the Securities or any amendment thereto (including the prospectus subject to
completion, if any, included in the Original Registration Statement or any
amendment thereto at the time it was or is declared effective); the term
"Prospectus" means:
          (i)   if the Company relies on Rule 434 under the Act, the Term Sheet
     relating to the Securities that is first filed pursuant to Rule 424(b)(7)
     under the Act, together with the Preliminary Prospectus identified therein
     that such Term Sheet supplements;

                                       2.
<PAGE>

          (ii)  if the Company does not rely on Rule 434 under the Act, the
     prospectus first filed with the Commission pursuant to Rule 424(b) under
     the Act; or

          (iii) if the Company does not rely on Rule 434 under the Act and if

     Act, the prospectus included in the Registration Statement;

and the term "Term Sheet" means any term sheet that satisfies the requirements
of Rule 434 under the Act.  Any reference herein to the "date" of a Prospectus
that includes a Term Sheet shall mean the date of such Term Sheet.

          (b) The Commission has not issued any order preventing or suspending
use of any Preliminary Prospectus. When any Preliminary Prospectus was filed
with the Commission it (i) contained all statements required to be stated
therein in accordance with, and complied in all material respects with the
requirements of, the Act and the rules and regulations of the Commission
thereunder and (ii) did not include any untrue statement of a material fact or
omit to state any material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading; provided that solely with respect to any Preliminary Prospectus as
filed with the Commission prior to May 28, 1999, the foregoing shall be subject
to changes in the Preliminary Prospectus in response to comments received from
the Commission and to blanks in the Preliminary Prospectus which are apparent on
their face as blanks. When the Registration Statement or any amendment thereto
was or is declared effective, it (i) contained or will contain all statements
required to be stated therein in accordance with, and complied or will comply in
all material respects with the requirements of, the Act and the rules and
regulations of the Commission thereunder and (ii) did not or will not include
any untrue statement of a material fact or omit to state any material fact
necessary to make the statements therein not misleading. When the Prospectus or
any Term Sheet that is a part thereof or any amendment or supplement to the
Prospectus is filed with the Commission pursuant to Rule 424(b) (or, if the
Prospectus or part thereof or such amendment or supplement is not required to be
so filed, when the Registration Statement or the amendment thereto containing
such amendment or supplement to the Prospectus was or is declared effective) and
on the Firm Closing Date and any Option Closing Date (both as hereinafter
defined), the Prospectus, as amended or supplemented at any such time, (i)
contained or will contain all statements required to be stated therein in
accordance with, and complied or will comply in all material respects with the
requirements of the Act and the rules and regulations of the Commission
thereunder and (ii) did not or will not include any untrue statement of a
material fact or omit to state any material fact necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading. The foregoing provisions of this paragraph (b) do not
apply to statements or omissions made in any Preliminary Prospectus, the
Registration Statement or any amendment thereto or the Prospectus or any
amendment or supplement thereto in reliance upon and in conformity with written
information furnished to the Company by any Underwriter through the
Representatives specifically for use therein.

          (c) If the Company has elected to rely on Rule 462(b), (i) the Company
has filed a Rule 462(b) Registration Statement in compliance with and that is
effective upon filing pursuant to Rule 462(b) and has received confirmation of
its receipt and (ii) the Company has

                                       3.
<PAGE>

given irrevocable instructions for transmission of the applicable filing fee in
connection with the filing of the Rule 462(b) Registration Statement in
compliance with Rule 111 promulgated under the Act or the Commission has
received payment of such filing fee.

          (d) The Company has been duly organized and is validly existing as a
corporation in good standing under the laws of the State of Delaware and is duly
qualified to transact business as a foreign corporation and is in good standing
under the laws of all other jurisdictions where the ownership or leasing of its
properties or the conduct of its business requires such qualification, except
where the failure to be so qualified would not, singly or in the aggregate, have
a material adverse change in the condition (financial or otherwise), management,
business prospects, net worth, or results of the operations of the Company (a
"Material Adverse Effect").

          (e) The Company has full corporate power to own or lease its
properties and conduct its business as described in the Registration Statement
and the Prospectus or, if the Prospectus is not in existence, the most recent
Preliminary Prospectus; and the Company has full corporate power to enter into
this Agreement and to carry out all the terms and provisions hereof to be
carried out by it.

          (f) The Company has an authorized, issued and outstanding
capitalization as set forth in the Prospectus or, if the Prospectus is not in
existence, the most recent Preliminary Prospectus. All of the issued shares of
capital stock of the Company have been duly authorized and validly issued, are
fully paid and nonassessable and were issued in compliance with all applicable
federal and state securities laws and were not issued in violation of or subject
to any preemptive rights or other rights to subscribe for or purchase
securities. The Firm Securities and the Option Securities have been duly
authorized and at the Firm Closing Date or the related Option Closing Date (as
the case may be), after payment therefor in accordance herewith, will be validly
issued, fully paid and nonassessable. No holders of outstanding shares of
capital stock of the Company are entitled as such to any preemptive or other
rights to subscribe for any of the Securities, and no holder of securities of
the Company has any right which has not been fully exercised or waived to
require the Company to register the offer or sale of any securities owned by
such holder under the Act in the public offering contemplated by this Agreement.

          (g) The capital stock of the Company conforms to the description
thereof contained in the Prospectus or, if the Prospectus is not in existence,
the most recent Preliminary Prospectus.

          (h) Except as disclosed in the Prospectus (or, if the Prospectus is
not in existence, the most recent Preliminary Prospectus), there are no
outstanding (A) securities or obligations of the Company convertible into or
exchangeable for any capital stock of the Company, (B) warrants, rights or
options to subscribe for or purchase from the Company any such capital stock or
any such convertible or exchangeable securities or obligations, or (C)
obligations of the Company to issue any shares of capital stock, any such
convertible or exchangeable securities or obligations, or any such warrants,
rights or options.

          (i) The financial statements and schedules of the Company included in
the Registration Statement and the Prospectus (or, if the Prospectus is not in
existence, the most

                                       4.
<PAGE>

recent Preliminary Prospectus) fairly present the financial position of the
Company and the results of operations and changes in financial condition as of
the dates and periods therein specified. Such financial statements and schedules
have been prepared in accordance with generally accepted accounting principles
consistently applied throughout the periods involved (except as otherwise noted
therein). The selected financial data set forth under the caption "Selected
Financial Information" in the Prospectus (or, if the Prospectus is not in
existence, the most recent Preliminary Prospectus) fairly present, on the basis
stated in the Prospectus (or such Preliminary Prospectus), the information
included therein.

     (j) Arthur Andersen LLP, who have certified certain financial statements of
the Company and delivered their report with respect to the audited financial
statements and schedules included in the Registration Statement and the
Prospectus (or, if the Prospectus is not in existence, the most recent
Preliminary Prospectus), are independent public accountants as required by the
Act and the applicable rules and regulations thereunder.

     (k) The execution and delivery of this Agreement have been duly authorized
by the Company and this Agreement has been duly executed and delivered by the
Company, and, assuming the due authorization, execution and delivery by all
parties hereto other than the Company, constitutes a valid and binding
obligation of the Company, enforceable against the Company in accordance with
its terms, subject to bankruptcy, insolvency, reorganization and other laws of
general applicability relating to or affecting creditor's rights, general
equitable principles and public policy considerations.

     (l) No legal or governmental proceedings are pending to which the Company
is a party or to which the property of the Company is subject that are required
to be described in the Registration Statement or the Prospectus and are not
described therein (or, if the Prospectus is not in existence, the most recent
Preliminary Prospectus), and, to the Company's knowledge, no such proceedings
have been threatened against the Company or with respect to any of its
properties; and no contract or other document is required to be described in the
Registration Statement or the Prospectus or to be filed as an exhibit to the
Registration Statement that is not described therein (or, if the Prospectus is
not in existence, the most recent Preliminary Prospectus) or filed as required.

     (m) The issuance, offering and sale of the Securities to the Underwriters
by the Company pursuant to this Agreement, the compliance by the Company with
the other provisions of this Agreement and the consummation of the other
transactions herein contemplated do not require the consent, approval,
authorization, registration or qualification of or with any governmental
authority, except (A) such as have been obtained, (B) such as may be required
under state securities or blue sky laws, the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), and the rules and regulations thereunder and the
bylaws of the National Association of Securities Dealers, Inc., (C) if the
registration statement filed with respect to the Securities (as amended) is not
effective under the Act as of the time of execution hereof, such as may be
required (and shall be obtained as provided in this Agreement) under the Act,
and (D) with respect to any consents, approvals, authorizations, registrations
or qualifications other than those referred to in the foregoing clauses (A), (B)
and (C), where the failure to obtain any such consent, approval, authorization,
registration or qualification would not, in the aggregate, have a Material
Adverse Effect. The issuance, offering and sale of the Securities to the

Company with the other provisions of this Agreement and the consummation of the
other transactions herein contemplated do not conflict with or result in a
breach or violation of any of the terms and provisions of, or constitute a
default under, (A) any indenture, mortgage, deed of trust, lease or other
agreement or instrument to which the Company is a party or by which the Company
or its properties are bound, or (B) the charter documents or bylaws of the
Company, or (C) any statute or any judgment, decree, order, rule or regulation
of any court or other governmental authority or any arbitrator applicable to the
Company, except where such conflict, breach, violation or default would not, in
the aggregate, have a Material Adverse Effect.

     (n) Subsequent to the respective dates as of which information is given in
the Registration Statement and the Prospectus or, if the Prospectus is not in
existence, the most recent Preliminary Prospectus, the Company has not sustained
any loss or interference with their respective businesses or properties that has

calamity, whether or not covered by insurance, or from any labor dispute or any
legal or governmental proceeding and there has not been any Material Adverse
Effect, or any development involving a prospective Material Adverse Effect,
except in each case as described in or contemplated by the Prospectus or, if the
Prospectus is not in existence, the most recent Preliminary Prospectus.

     (o) The Company has not, directly or indirectly, (i) taken any action
designed to cause or to result in, or that has constituted or which might
reasonably be expected to constitute, the stabilization or manipulation of the
price of any security of the Company to facilitate the sale or resale of the
Securities or (ii) since the filing of the Registration Statement (A) sold, bid
for, purchased, or paid anyone any compensation for soliciting purchases of, the
Securities or (B) paid or agreed to pay to any person any compensation for
soliciting another to purchase any other securities of the Company, in each case
except as expressly contemplated by this Agreement.

Closing Date and (ii) the completion of the distribution of the Securities, will
not distribute any offering material in connection with the offering and sale of

any Preliminary Prospectus or the Prospectus or any amendment or supplement
thereto, or other materials, if any, permitted by (and in compliance with) the
Act.

     (q) Subsequent to the respective dates as of which information is given in

existence, the most recent Preliminary Prospectus), (i) the Company has not
incurred any material liability or obligation, direct or contingent, nor entered
into any material transaction not in the ordinary course of business; (ii) the
Company has not purchased any of its outstanding capital stock, nor declared,
paid or otherwise made any dividend or distribution of any kind on its capital

short-term debt or long-term debt of the Company, except in each case as
described in or contemplated by the Prospectus (or, if the Prospectus is not in
existence, the most recent Preliminary Prospectus).

                                       6.

     (r) The Company does not own any real property.  The Company has good and
marketable title to all personal property owned by it free and clear of any
security interests, liens, encumbrances, equities, claims and other defects,
except such as do not materially and adversely affect the value of such property
and do not interfere with the use made or proposed to be made of such property
by the Company, and any buildings held under lease by the Company are held under
valid, subsisting and enforceable leases, with such exceptions as are not
material and do not interfere with the use made or proposed to be made of such
buildings by the Company, in each case except as described in or contemplated by
the Prospectus (or, if the Prospectus is not in existence, the most recent
Preliminary Prospectus).

     (s) No labor dispute with the employees of the Company exists or, to the
best of the Company's knowledge, is threatened or imminent that could have a
Material Adverse Effect, except as described in or contemplated by the
Prospectus (or, if the Prospectus is not in existence, the most recent
Preliminary Prospectus).

     (t) The Company owns or possesses, or can acquire on reasonable terms, the
right to use all patents, patent applications, trademarks, service marks, trade
names, licenses, copyrights and proprietary or other confidential information
currently employed by it in connection with its business, except where the
failure to own or possess, or to be able to acquire on reasonable terms, the
right to use any such items would not, in the aggregate, have a Material Adverse
Effect, and the Company has not received any notice of infringement of or
conflict with asserted rights of any third party with respect to any such items
except where such infringements or conflicts, in the aggregate, if the subject
of an unfavorable decision, ruling or finding, would not have a Material Adverse
Effect, except as described in or contemplated by the Prospectus (or, if the
Prospectus is not in existence, the most recent Preliminary Prospectus).

     (u) The Company is insured by insurers of recognized financial
responsibility against such losses and risks and in such amounts as are prudent
and customary in the businesses in which it is engaged; the Company has not been
refused any insurance coverage sought or applied for; and the Company has no
reason to believe that it will not be able to renew its existing insurance
coverage as and when such coverage expires or to obtain similar coverage from
similar insurers as may be necessary to continue its business at a cost that
would not have a Material Adverse Effect, except as described in or contemplated
by the Prospectus (or, if the Prospectus is not in existence, the most recent
Preliminary Prospectus).

     (v) The Company possesses all certificates, authorizations and permits
issued by the appropriate federal, state or foreign regulatory authorities
necessary to conduct its business, except where the failure to possess such
certificates, authorizations and permits would not, in the aggregate, have a

therefrom, as described in the Prospectus.

     (x)  The Company has filed all foreign, federal, state and local tax
returns that are required to be filed or has requested extensions thereof

that is currently being contested in good faith or as described in or

     (z)  Each certificate signed by any officer of the Company and delivered to
the Representatives or counsel for the Underwriters shall be deemed to be a

reasonable intervals and appropriate action is taken with respect to any
differences.

     (cc) No default exists, and no event has occurred which, with notice or

observance of any term, covenant or condition of any indenture, mortgage, deed

                (dd) The merger of the Predecessor with and into the Company
(the "Merger") became effective on _____________, 1999 upon the filing of the
Agreement and Plan of Merger dated _____________, 1999, between the Predecessor
and the Company (the "Merger Agreement") with the Secretary of State of the
State of Delaware in accordance with Sections 265 and 251 of the Delaware
General Corporation Law and Section 18-209 of the Delaware Limited Liability
Company Act. When the Merger became effective (the time of such effectiveness
being hereinafter referred to as the "Effective Time"), the separate existence
of the Predecessor ceased and the Merger had the other effects specified in
Section 259(a) of the Delaware General Corporation Law and Section 18-209(g) of
the Delaware Limited Liability Company Act. At the Effective Time, (i) each
common unit in the Predecessor outstanding immediately prior to the Effective
Time was converted into the right to receive shares of Common Stock, (ii) each
then-outstanding option to purchase common units in the Predecessor was assumed
by the Company and became an option to acquire shares of Common Stock, and (iii)
each then-outstanding warrant to purchase common units of the Predecessor became
exercisable to purchase shares of Common Stock, in each case as contemplated by
Article II of the Merger Agreement. Prior to the Effective Time, the Merger
Agreement and the Merger were duly approved by the Predecessor by all requisite
limited liability company action, including all requisite action by its managers
and members, and by the Company by all requisite corporate action, including all
requisite action of its directors and stockholders. The consummation of the
Merger did not (i) violate any statute or regulation applicable to, or any
order, writ, judgment, injunction, decree, determination or award entered
against, the Predecessor or the Company or (ii) conflict with or breach any of
the terms of, or constitute a default under, the Company's Amended and Restated
Certificate of Incorporation or Amended and Restated Bylaws, the Predecessor's
Second Amended and Restated Operating Agreement or any material agreement or
instrument to which the Predecessor or the Company was or is a party or by which
the Predecessor or the Company was or is bound. To the best of the Company's
knowledge, there is no action, proceeding or investigation pending or threatened
that questions the validity of such merger, nor is there any basis therefor.

        3.      Purchase, Sale and Delivery of the Securities.
                ---------------------------------------------

                (a)  On the basis of the representations, warranties, agreements
and covenants herein contained and subject to the terms and conditions herein
set forth, the Company agrees to issue and sell to each of the Underwriters, and
each of the Underwriters, severally and not jointly, agrees to purchase from the
Company, at a purchase price of $________ per share, the number of Firm
Securities set forth opposite the name of such Underwriter in Schedule 1 hereto.
One or more certificates in definitive form for the Firm Securities that the
several Underwriters have agreed to purchase hereunder, and in such denomination
or denominations and registered in such name or names as the Representatives
request upon notice to the Company at least 48 hours prior to the Firm Closing
Date, shall be delivered by or on behalf of the Company to the Representatives
for the respective accounts of the Underwriters, against payment by or on behalf
of the Underwriters of the purchase price therefor by wire transfer in same-day
funds (the "Wired Funds") to the account of the Company. Such delivery of and
payment for the Firm Securities shall be made at the offices of Cooley Godward
LLP, 4365 Executive Drive, Suite 1100, San Diego, California 92121, at 6:30
A.M., San Diego time, on __________, 1999, or at such other place, time or date
as the Representatives and the Company may agree upon or as the Representatives
may determine pursuant to Section 9 hereof, such time and date of

                                       9.
<PAGE>

delivery against payment being herein referred to as the "Firm Closing Date".
The Company will make such certificate or certificates for the Firm Securities
available for checking and packaging by the Representatives at the offices in
New York, New York of the Company's transfer agent or registrar or of Prudential
Securities Incorporated at least 24 hours prior to the Firm Closing Date.

        (b) For the purpose of covering any over-allotments in connection with
the distribution and sale of the Firm Securities as contemplated by the
Prospectus, the Company hereby grants to the several Underwriters an option to
purchase, severally and not jointly, the Option Securities. The purchase price
to be paid for any Option Securities shall be the same price per share as the
price per share for the Firm Securities set forth above in paragraph (a) of this
Section 3. The option granted hereby may be exercised as to all or any part of
the Option Securities from time to time within 30 days after the date of the
Prospectus (or, if such 30th day shall be a Saturday or Sunday or a holiday, on
the next business day thereafter when the New York Stock Exchange is open for
trading). The Underwriters shall not be under any obligation to purchase any of
the Option Securities prior to the exercise of such option. The Representatives
may from time to time exercise the option granted hereby by giving notice in
writing or by telephone (confirmed in writing) to the Company setting forth the
aggregate number of Option Securities as to which the several Underwriters are
then exercising the option and the date and time for delivery of and payment for
such Option Securities. Any such date of delivery shall be determined by the
Representatives but shall not be earlier than two business days or later than
five business days after such exercise of the option and, in any event, shall
not be earlier than the Firm Closing Date. The time and date set forth in such
notice, or such other time on such other date as the Representatives and Company
may agree upon or as the Representatives may determine pursuant to Section 9
hereof, is herein called the "Option Closing Date" with respect to such Option
Securities. Upon exercise of the option as provided herein, the Company shall
become obligated to sell to each of the several Underwriters, and, subject to
the terms and conditions herein set forth, each of the Underwriters (severally
and not jointly) shall become obligated to purchase from the Company, the same
percentage of the total number of the Option Securities as to which the several
Underwriters are then exercising the option as such Underwriter is obligated to
purchase of the aggregate number of Firm Securities, as adjusted by the
Representatives in such manner as they deem advisable to avoid fractional
shares. If the option is exercised as to all or any portion of the Option
Securities, one or more certificates in definitive form for such Option
Securities, and payment therefor, shall be delivered on the related Option
Closing Date in the manner, and upon the terms and conditions, set forth in
paragraph (a) of this Section 3, except that reference therein to the Firm
Securities and the Firm Closing Date shall be deemed, for purposes of this
paragraph (b), to refer to such Option Securities and Option Closing Date,
respectively.

        (c) The Company hereby acknowledges that the wire transfer by or on
behalf of the Underwriters of the purchase price for any Securities does not
constitute closing of a purchase and sale of the Securities. Only execution and
delivery of a receipt for Securities by the Underwriters indicates completion of
the closing of a purchase of the Securities from the Company. Furthermore, in
the event that the Underwriters wire funds to the Company prior to the
completion of the closing of a purchase of Securities, the Company hereby
acknowledges that until the Underwriters execute and deliver a receipt for the
Securities, by facsimile or otherwise, the Company will not be entitled to the
Wired Funds and shall return the Wired Funds

                                      10.
<PAGE>

to the Underwriters as soon as practicable (by wire transfer of same-day funds)
upon demand. In the event that the closing of a purchase of Securities is not
completed and the Wired Funds are not returned by the Company to the
Underwriters on the same day the Wired Funds were received by the Company, the
Company agrees to pay to the Underwriters in respect of each day the Wired Funds
are not returned by it, in same-day funds, interest on the amount of such Wired
Funds in an amount representing the Underwriters' cost of financing as
reasonably determined by Prudential Securities Incorporated.

                (d) It is understood that any of you, individually and not as
one of the Representatives, may (but shall not be obligated to) make payment on
behalf of any Underwriter or Underwriters for any of the Securities to be
purchased by such Underwriter or Underwriters. No such payment shall relieve
such Underwriter or Underwriters from any of its or their obligations hereunder.

        4.      Offering by the Underwriters.  Upon your authorization of the
                ----------------------------
release of the Firm Securities, the several Underwriters propose to offer the
Firm Securities for sale to the public upon the terms set forth in the
Prospectus.

        5.      Covenants of the Company.  The Company covenants and agrees
                ------------------------
with each of the Underwriters that:

                (a) The Company will use its best efforts to cause the
     Registration Statement, if not effective at the time of execution of this
     Agreement, and any amendments thereto to become effective as promptly as
     possible. If required, the Company will file the Prospectus or any Term
     Sheet that constitutes a part thereof and any amendment or supplement
     thereto with the Commission in the manner and within the time period
     required by Rules 434 and 424(b) under the Act. During any time when a
     prospectus relating to the Securities is required to be delivered under the
     Act, the Company (i) will comply with all requirements imposed upon it by
     the Act and the rules and regulations of the Commission thereunder to the
     extent necessary to permit the continuance of sales of or dealings in the
     Securities in accordance with the provisions hereof and of the Prospectus,
     as then amended or supplemented, and (ii) will not file with the Commission
     the Prospectus or the amendment referred to in the second sentence of
     Section 2(a) hereof, any amendment or supplement to the Prospectus or any
     amendment to any Registration Statement unless the Representatives
     previously have been advised and furnished with a copy thereof within a
     reasonable period of time prior to the proposed filing and as to which
     filing the Representatives shall not have given their consent, which
     consent shall not have been unreasonably withheld. The Company will prepare
     and file with the Commission, in accordance with the rules and regulations
     of the Commission, promptly upon request by the Representatives or counsel
     for the Underwriters, any amendments to any Registration Statement or
     amendments or supplements to the Prospectus that may be necessary or
     advisable in connection with the distribution of the Securities by the
     several Underwriters, and will use its best efforts to cause any such
     amendment to the Registration Statement to be declared effective by the
     Commission as promptly as possible. The Company will advise the
     Representatives, promptly after receiving notice thereof, of the time when
     any Registration Statement or any amendment thereto has been filed or
     declared effective or the Prospectus or any amendment or supplement thereto
     has been filed and will provide evidence satisfactory to the
     Representatives of each such filing or effectiveness.

                                      11.
<PAGE>

        (b) The Company will advise the Representatives, promptly after
receiving notice or obtaining knowledge thereof, of (i) the issuance by the
Commission of any stop order suspending the effectiveness of the Original
Registration Statement or any Rule 462(b) Registration Statement or any
amendment thereto or any order preventing or suspending the use of any
Preliminary Prospectus or the Prospectus or any amendment or supplement thereto,
(ii) the suspension of the qualification of the Securities for offering or sale
in any jurisdiction, (iii) the institution, threatening or contemplation of any
proceeding for any such purpose or (iv) any request made by the Commission for
amending the Original Registration Statement or any Rule 462(b) Registration
Statement, for amending or supplementing the Prospectus or for additional
information. The Company will use its best efforts to prevent the issuance of
any such stop order and, if any such stop order is issued, to obtain the
withdrawal thereof as promptly as possible.

        (c) The Company will arrange for the qualification of the Securities for
offering and sale under the securities or blue sky laws of such jurisdictions as
the Representatives may designate and will continue such qualifications in
effect for as long as may be necessary to complete the distribution of the
Securities, provided, however, that in connection therewith the Company shall
not be required to qualify as a foreign corporation or to execute a general
consent to service of process in any jurisdiction.

        (d) If, at any time prior to the later of (i) the final date when a
prospectus relating to the Securities is required to be delivered under the Act
or (ii) the Option Closing Date, any event occurs as a result of which the
Prospectus, as then amended or supplemented, would include any untrue statement
of a material fact or omit to state a material fact necessary in order to make
the statements therein, in the light of the circumstances under which they were
made, not misleading, or if for any other reason it is necessary at any time to
amend or supplement the Prospectus to comply with the Act or the rules or
regulations of the Commission thereunder, the Company will promptly notify the
Representatives thereof and, subject to Section 5(a) hereof, will prepare and
file with the Commission, at the Company's expense, an amendment to the
Registration Statement or an amendment or supplement to the Prospectus that
corrects such statement or omission or effects such compliance.

        (e) The Company will, without charge, provide (i) to the Representatives
and to counsel for the Underwriters a conformed copy of the registration
statement originally filed with respect to the Securities and each amendment
thereto (in each case including exhibits thereto) or any Rule 462(b)
Registration Statement, certified by the Secretary or an Assistant Secretary of
the Company to be true and complete copies thereof as filed with the Commission
by electronic transmission, (ii) to each other Underwriter, a conformed copy of
such registration statement or any Rule 462(b) Registration Statement and each
amendment thereto (in each case without exhibits thereto) and (iii) so long as a
prospectus relating to the Securities is required to be delivered under the Act,
as many copies of each Preliminary Prospectus or the Prospectus or any amendment
or supplement thereto as the Representatives may reasonably request; without
limiting the application of clause (iii) of this sentence, the Company, not
later than (A) 6:00 P.M., New York City time, on the date of determination of
the public offering price, if such determination occurred at or prior to 10:00
A.M., New York City time, on such date or (B) 2:00 P.M., New York City time, on
the business day following the date of determination of the public offering
price, if such determination occurred after 10:00 A.M., New York City time, on
such date, will deliver to the Underwriters, without charge, as many copies of
the Prospectus and any

                                      12.
<PAGE>

amendment or supplement thereto as the Representatives may reasonably request
for purposes of confirming orders that are expected to settle on the Firm
Closing Date.

        (f) The Company, as soon as practicable, will make generally available
to its securityholders and to the Representatives an earnings statement of the
Company and its subsidiaries that satisfies the provisions of Section 11(a) of
the Act and Rule 158 thereunder.

        (g) The Company will apply the net proceeds from the sale of the
Securities as set forth under "Use of Proceeds" in the Prospectus.

        (h) The Company will not, directly or indirectly, without the prior
written consent of Prudential Securities Incorporated on behalf of the
Underwriters, offer, sell, offer to sell, contract to sell, pledge, grant any
option to purchase or otherwise sell or dispose (or announce any offer, sale,
offer of sale, contract of sale, pledge, grant of any option to purchase or
other sale or disposition) of any shares of Common Stock or any securities
convertible into, or exchangeable or exercisable for, shares of Common Stock for
a period of 180 days after the date hereof, except pursuant to this Agreement
and except for (i) issuances of Common Stock pursuant to the exercise of
warrants or employee stock options of the Company to persons who have signed an
agreement referred to in Section 7(f), and (ii) the grant of employee stock
options with vesting schedules consistent with past practice under the option
plans of the Company.

        (i) Until the date 25 days following the completion of the offering of
the Securities contemplated hereby, the Company will not, directly or
indirectly, (i) take any action designed to cause or to result in, or that has
constituted or which might reasonably be expected to constitute, the
stabilization or manipulation of the price of any security of the Company to
facilitate the sale or resale of the Securities or (ii) (A) sell, bid for,
purchase, or pay anyone any compensation for soliciting purchases of, the
Securities or (B) pay or agree to pay to any person any compensation for
soliciting another to purchase any other securities of the Company, in each case
except as expressly contemplated in this Agreement.

        (j) The Company will use its best efforts to obtain the agreements
described in Section 7(f) hereof prior to the Firm Closing Date.

        (k) If at any time during the 25-day period after the Registration
Statement becomes effective or the period prior to the Option Closing Date, any
rumor, publication or event relating to or affecting the Company shall occur as
a result of which in your opinion the market price of the Common Stock has been
or is likely to be materially affected (regardless of whether such rumor,
publication or event necessitates a supplement to or amendment of the
Prospectus), the Company will, after notice from you advising the Company to the
effect set forth above, forthwith prepare, consult with you concerning the
substance of, and disseminate a press release or other public statement,
reasonably satisfactory to you, responding to or commenting on such rumor,
publication or event, unless the Company, after consultation with its counsel
and underwriters' counsel, determines that such action would be inappropriate.

        (l) If the Company elects to rely on Rule 462(b), the Company shall both
file a Rule 462(b) Registration Statement with the Commission in compliance with
Rule 462(b) and pay the applicable fees in accordance with Rule 111 promulgated
under the Act by the earlier of

                                      13.

          (m) The Company will cause the Securities to be duly included for

Market") prior to the Firm Closing Date. The Company will use its reasonable
best efforts to ensure that the Securities remain included for quotation on the
Nasdaq National Market or otherwise become listed on the New York Stock Exchange
following the Firm Closing Date.

     6.   Expenses.  The Company will pay all costs and expenses incident to
          --------
the performance of its obligations under this Agreement, whether or not the

Company to perform all obligations and satisfy all conditions on its part to be
performed or satisfied hereunder other than by reason of a default by any of the
Underwriters, the Company will reimburse the Underwriters severally upon demand
for all out-of-pocket expenses (including counsel fees and disbursements) that
shall have been incurred by them in connection with the proposed purchase and
sale of the Securities.  The Company shall not in any event be liable to any of
the Underwriters for the loss of anticipated profits from the transactions
covered by this Agreement.

Agreement or any other document filed as an exhibit to the Original Registration
Statement or any Rule 462(b) Registration Statement.

     Such counsel shall also have furnished to the Representatives a written
statement, dated the Firm Closing Date, addressed to the Underwriters, to the
effect that (x) such counsel has participated in the preparation of the Original
Registration Statement and any Rule 462(b) Registration Statement, and (y) based
upon such participation, no facts have come to their attention which lead them
to believe that the Original Registration Statement or any 462(b) Registration
Statement (other than the financial statements, related schedules and other
statistical and financial data included therein, as to which such counsel need
express no belief), as of the time it became effective under the Act, contained
any untrue statement of a material fact or omitted to state a material fact
required to be stated therein or necessary in order to make the statements
therein not misleading, or that the Prospectus (other than the financial
statements, related schedules and other statistical and financial data included
therein, as to which such counsel need express no belief), as of its date or the
date of such opinion, contained or contains any untrue statement of a material
fact or omitted or omits to state a material fact required to be stated therein
or necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading.  The foregoing opinion
and statement may be qualified by a statement to the effect that such counsel
has not independently verified, does not pass upon and does not assume any
responsibility for, the accuracy, completeness or fairness of the statements
contained in the Original Registration Statement, any Rule 462(b) Registration
Statement or the Prospectus.

     In rendering such opinion, such counsel may rely, as to certain factual
matters, without any independent investigation, inquiry or verification, upon
statements or certificates of officers and other representatives of the Company
(including the representations of the Company contained in this Agreement),
certificates of public officials, certificates or written statements of officers
of departments of various jurisdictions having custody of documents relating to
the corporate existence, foreign qualification and good standing of the Company
and written statements of representatives of The Nasdaq Stock Market.

     References to the Original Registration Statement, any Rule 462(b)
Registration Statement and the Prospectus in this paragraph (b) shall include
any amendment to supplement thereto at the date of such opinion.

          (d)     The Representatives shall have received an opinion, dated the
Firm Closing Date, of Cooley Godward LLP, counsel for the Underwriters, with

Representatives may reasonably require, and the Company shall have furnished to
such counsel such documents as such counsel may reasonably request for the
purpose of enabling them to pass upon such matters.

          (e)     The Representatives shall have received from Arthur Andersen
LLP a letter or letters dated, respectively, the date hereof and the Firm
Closing Date, in form and substance satisfactory to the Representatives, to the
effect that:

                  (i)    they are certified public independent accountants with
respect to the Company within the meaning of the Act and the applicable
published rules and regulations thereunder;

                  (ii)   in their opinion, the financial statements and
schedules audited by them and included in the Registration Statement and the
Prospectus comply in form in all material respects with the applicable
accounting requirements of the Act and the related published rules and
regulations;

                  (iii)   on the basis of a reading of the latest available
interim unaudited condensed financial statements of the Company, carrying out
certain specified procedures (which do not constitute an examination made in
accordance with generally accepted auditing standards) that would not
necessarily reveal matters of significance with respect to the comments set
forth in this paragraph (iii), a reading of the minute books of the
shareholders, the board of directors and any committees thereof of the Company,
and inquiries of certain officials of the Company who have responsibility for
financial and accounting matters, nothing came to their attention that caused
them to believe that:

                  (A)    the unaudited condensed financial statements of the
          Company included in the Registration Statement and the Prospectus do
          not comply as to form in all material respects with the applicable
          accounting requirements of the Act and the related published rules and
          regulations thereunder or are not in conformity with generally
          accepted accounting principles applied on a basis substantially
          consistent with that of the audited financial statements included in
          the Registration Statement and the Prospectus;

                  (B)    at a specific date not more than five business days
          prior to the date of such letter, there were any changes in the
          capital stock or long-term debt of the Company or any decreases in net
          current assets or stockholders' equity of the Company, in each case
          compared with amounts shown on the March 31, 1999 unaudited balance
          sheet included in the Registration Statement and the Prospectus, or
          for the period from the date of such balance sheet to such specified
          date there were any decreases, as compared with the quarterly period
          ending as of the date of such balance sheet, in total revenues,
          operating loss, net loss or basic and diluted loss per common share of
          the Company, except in all instances for changes, decreases or
          increases set forth in the Registration Statement.

                  (iv)   they have carried out certain specified procedures, not
constituting an audit, with respect to certain amounts, percentages and
financial information that are derived from the general accounting records of
the Company and are included in the Registration Statement and the Prospectus

compared such amounts, percentages and financial information with such records
of the Company and with information derived from such records and have found
them to be in agreement, excluding any questions of legal interpretation.

     In the event that the letters referred to above set forth any such changes,
decreases or increases, it shall be a further condition to the obligations of
the Underwriters that (A) such letters shall be accompanied by a written
explanation of the Company as to the significance thereof, unless the
Representatives deem such explanation unnecessary, and (B) such changes,
decreases or increases do not, in the sole judgment of the Representatives, make
it impractical or inadvisable to proceed with the purchase and delivery of the
Securities as contemplated by the Registration Statement, as amended as of the
date hereof.

     References to the Registration Statement and the Prospectus in this
paragraph (d) with respect to either letter referred to above shall include any

          (f)     The Representatives shall have received a certificate, dated
the Firm Closing Date, of the chief executive officer and the chief financial
officer of the Company to the effect that:

                  (i)    the representations and warranties of the Company in
this Agreement are true and correct as if made on and as of the Firm Closing
Date; the Registration Statement, as amended as of the Firm Closing Date, does
not include any untrue statement of a material fact or omit to state any
material fact necessary to make the statements therein not misleading, and the
Prospectus, as amended or supplemented as of the Firm Closing Date, does not
include any untrue statement of a material fact or omit to state any material
fact necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading; and the Company has
performed all covenants and agreements and satisfied all conditions on its part
to be performed or satisfied at or prior to the Firm Closing Date;

                  (ii)   no stop order suspending the effectiveness of the
Registration Statement or any amendment thereto has been issued, and no
proceedings for that purpose have been instituted or threatened or, to the best
of the Company's knowledge, are contemplated by the Commission; and

                  (iii)   subsequent to the respective dates as of which
information is given in the Registration Statement and the Prospectus, the
Company has not sustained any loss or interference with its business or
properties that has had a Material Adverse Effect from fire, flood, hurricane,
accident or other calamity, whether or not covered by insurance, or from any
labor dispute or any legal or governmental proceeding, and there has not been
any event having a Material Adverse Effect, or any development involving a
prospective Material Adverse Effect, except in each case as described in or
contemplated by the Prospectus (exclusive of any amendment or supplement
thereto).

                                      20.
<PAGE>

          (g)     The Representatives shall have received from each person who
is a director, officer or shareholder of the Company an agreement to the effect
that such person will not, directly or indirectly, without the prior written
consent of Prudential Securities Incorporated, on behalf of the Underwriters,
offer, sell, offer to sell, contract to sell, pledge, grant any option to
purchase or otherwise sell or dispose (or announce any offer, sale, offer of
sale, contract of sale, pledge, grant of any option to purchase or other sale or
disposition) of any shares of Common Stock or any securities convertible into,
or exchangeable or exercisable for, shares of Common Stock for a period of 180
days after the date of this Agreement.

          (h)     On or before the Firm Closing Date, the Representatives and
counsel for the Underwriters shall have received such further certificates,
documents or other information as they may have reasonably requested from the
Company.

          (i)     Prior to the commencement of the offering of the Securities,
the Securities shall have been included for trading in the Nasdaq National
Market, subject to official notice of issuance.

     All opinions, certificates, letters and documents delivered pursuant to
this Agreement will comply with the provisions hereof only if they are
reasonably satisfactory in all material respects to the Representatives and
counsel for the Underwriters.  The Company shall furnish to the Representatives
such conformed copies of such opinions, certificates, letters and documents in
such quantities as the Representatives and counsel for the Underwriters shall
reasonably request.

     The respective obligations of the several Underwriters to purchase and pay
for any Option Securities shall be subject, in their discretion, to each of the
foregoing conditions to purchase the Firm Securities, except that all references
to the Firm Securities and the Firm Closing Date shall be deemed to refer to
such Option Securities and the related Option Closing Date, respectively.

     8.   Indemnification and Contribution.
          --------------------------------

          (a)     The Company agrees to indemnify and hold harmless each
Underwriter and each person, if any, who controls any Underwriter within the
meaning of Section 15 of the Act or Section 20 of the Exchange Act against any
losses, claims, damages or liabilities, joint or several, to which such
Underwriter or such controlling person may become subject under the Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon:

                  (i)    any untrue statement or alleged untrue statement made
by the Company in Section 2 of this Agreement;

                  (ii)   any untrue statement or alleged untrue statement of any
material fact contained in (A) the Registration Statement or any amendment
thereto, any Preliminary Prospectus or the Prospectus or any amendment or
supplement thereto or (B) any application or other document, or any amendment or
supplement thereto, executed by the Company or based upon written information
furnished by or on behalf of the Company filed in any jurisdiction in order to
qualify the Securities under the securities or blue sky laws thereof or filed
with the Commission or any securities association or securities exchange (each
an "Application");

                                      21.
<PAGE>

                  (iii)   the omission or alleged omission to state in the
Registration Statement or any amendment thereto, any Preliminary Prospectus or
the Prospectus or any amendment or supplement thereto, or any Application a
material fact required to be stated therein or necessary to make the statements
therein not misleading; or

                  (iv)   any untrue statement or alleged untrue statement of any
material fact contained in any audio or visual materials prepared by the Company
or based upon written information furnished by or on behalf of the Company,
including, without limitation, slides, videos, films, tape recordings, used in
connection with the marketing of the Securities, including, without limitation,
statements communicated to securities analysts employed by the Underwriters;

and will reimburse, as incurred, each Underwriter and each such controlling
person for any legal or other expenses reasonably incurred by such Underwriter
or such controlling person in connection with investigating, defending against
or appearing as a third-party witness in connection with any such loss, claim,
damage, liability or action; provided, however, that the Company will not be
liable in any such case to the extent that any such loss, claim, damage or
liability arises out of or is based upon any untrue statement or alleged untrue
statement or omission or alleged omission made in such Registration Statement or
any amendment thereto, any Preliminary Prospectus, the Prospectus or any
amendment or supplement thereto or any Application in reliance upon and in
conformity with written information furnished to the Company by or on behalf of
such Underwriter through the Representatives specifically for use therein; and
provided, further, that the Company will not be liable to any Underwriter or any
person controlling such Underwriter with respect to any such untrue statement or
alleged untrue statement or omission or alleged omission made in any Preliminary
Prospectus that is corrected in the Prospectus (or any amendment or supplement
thereto) if the person asserting any such loss, claim, damage or liability
purchased Securities from such Underwriter but was not sent or given a copy of
the Prospectus (as amended or supplemented) at or prior to the written
confirmation of the sale of such Securities to such person in any case where
such delivery of the Prospectus (as amended or supplemented) is required by the
Act, unless such failure to deliver the Prospectus (as amended or supplemented)
was a result of noncompliance by the Company with Section 5(d) and (e) of this
Agreement.  This indemnity agreement will be in addition to any liability which
the Company may otherwise have.  The Company will not, without the prior written
consent of the Underwriter or Underwriters purchasing, in the aggregate, more
than fifty percent (50%) of the Securities, settle or compromise or consent to
the entry of any judgment in any pending or threatened claim, action, suit or
proceeding in respect of which indemnification may be sought hereunder (whether
or not any such Underwriter or any person who controls any such Underwriter
within the meaning of Section 15 of the Act or Section 20 of the Exchange Act is
a party to such claim, action, suit or proceeding), unless such settlement,
compromise or consent includes an unconditional release of all of the
Underwriters and such controlling persons from all liability arising out of such
claim, action, suit or proceeding.

          (b)     Each Underwriter, severally and not jointly, will indemnify
and hold harmless the Company, each of its directors, each of its officers who
signed the Registration Statement and each person, if any, who controls the
Company within the meaning of Section 15 of the Act or Section 20 of the
Exchange Act against any losses, claims, damages or liabilities to which the
Company or any such director, officer or controlling person may become subject

                                      22.
<PAGE>

under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon (i)
any untrue statement or alleged untrue statement of any material fact contained
in the Registration Statement or any amendment thereto, any Preliminary
Prospectus or the Prospectus or any amendment or supplement thereto, or any
Application or (ii) the omission or the alleged omission to state therein a
material fact required to be stated in the Registration Statement or any
amendment thereto, any Preliminary Prospectus or the Prospectus or any amendment
or supplement thereto, or any Application or necessary to make the statements
therein not misleading, in each case to the extent, but only to the extent, that
such untrue statement or alleged untrue statement or omission or alleged
omission was made in reliance upon and in conformity with written information
furnished to the Company by such Underwriter through the Representatives
specifically for use therein: and, subject to the limitation set forth
immediately preceding this clause, will reimburse, as incurred, any legal or
other expenses reasonably incurred by the Company or any such director, officer
or controlling person in connection with investigating or defending any such
loss, claim, damage, liability or any action in respect thereof. This indemnity
agreement will be in addition to any liability which such Underwriter may
otherwise have.

          (c)     Promptly after receipt by an indemnified party under this
Section 8 of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against the indemnifying party
under this Section 8, notify the indemnifying party of the commencement thereof;
but the omission so to notify the indemnifying party will not relieve it from
any liability which it may have to any indemnified party otherwise than under
this Section 8. In case any such action is brought against any indemnified
party, and it notifies the indemnifying party of the commencement thereof, the
indemnifying party will be entitled to participate therein and, to the extent
that it may wish, jointly with any other indemnifying party similarly notified,
to assume the defense thereof, with counsel satisfactory to such indemnified
party; provided, however, that if the defendants in any such action include both
the indemnified party and the indemnifying party and the indemnified party shall
have reasonably concluded that there may be one or more legal defenses available
to it and/or other indemnified parties which are different from or additional to
those available to the indemnifying party, the indemnifying party shall not have
the right to direct the defense of such action on behalf of such indemnified
party or parties and such indemnified party or parties shall have the right to
select separate counsel to defend such action on behalf of such indemnified
party or parties. After notice from the indemnifying party to such indemnified
party of its election so to assume the defense thereof and approval by such
indemnified party of counsel appointed to defend such action, the indemnifying
party will not be liable to such indemnified party under this Section 8 for any
legal or other expenses, other than reasonable costs of investigation,
subsequently incurred by such indemnified party in connection with the defense
thereof, unless (i) the indemnified party shall have employed separate counsel
in accordance with the proviso to the next preceding sentence (it being
understood, however, that in connection with such action the indemnifying party
shall not be liable for the expenses of more than one separate counsel (in
addition to local counsel) in any one action or separate but substantially
similar actions in the same jurisdiction arising out of the same general
allegations or circumstances, designated by the Representatives in the case of
paragraph (a) of this Section 8, representing the indemnified parties under such
paragraph (a) who are parties to such action or actions) or (ii) the
indemnifying party does not promptly retain counsel satisfactory to the
indemnified party or (iii) the indemnifying party has authorized the employment
of counsel for the indemnified party at

                                      23.
<PAGE>

the expense of the indemnifying party. After such notice from the indemnifying
party to such indemnified party, the indemnifying party will not be liable for
the costs and expenses of any settlement of such action effected by such
indemnified party without the consent of the indemnifying party.

          (d)     In circumstances in which the indemnity agreement provided for
in the preceding paragraphs of this Section 8 is unavailable or insufficient,
for any reason, to hold harmless an indemnified party in respect of any losses,
claims, damages or liabilities (or actions in respect thereof), each
indemnifying party, in order to provide for just and equitable contribution,
shall contribute to the amount paid or payable by such indemnified party as a
result of such losses, claims, damages or liabilities (or actions in respect
thereof) in such proportion as is appropriate to reflect (i) the relative
benefits received by the indemnifying party or parties on the one hand and the
indemnified party on the other from the offering of the Securities or (ii) if
the allocation provided by the foregoing clause (i) is not permitted by
applicable law, not only such relative benefits but also the relative fault of
the indemnifying party or parties on the one hand and the indemnified party on
the other in connection with the statements or omissions or alleged statements
or omissions that resulted in such losses, claims, damages or liabilities (or
actions in respect thereof), as well as any other relevant equitable
considerations. The relative benefits received by the Company on the one hand
and the Underwriters on the other shall be deemed to be in the same proportion
as the total proceeds from the offering (before deducting expenses) received by
the Company bear to the total underwriting discounts and commissions received by
the Underwriters. The relative fault of the parties shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact or the omission or alleged omission to state a material fact
relates to information supplied by the Company or the Underwriters, the parties'
relative intents, knowledge, access to information and opportunity to correct or
prevent such statement or omission, and any other equitable considerations
appropriate in the circumstances. The Company and the Underwriters agree that it
would not be equitable if the amount of such contribution were determined by pro
rata or per capita allocation (even if the Underwriters were treated as one
entity for such purpose) or by any other method of allocation that does not take
into account the equitable considerations referred to above in this paragraph
(d). Notwithstanding any other provision of this paragraph (d), no Underwriter
shall be obligated to make contributions hereunder that in the aggregate exceed
the total public offering price of the Securities purchased by such Underwriter
under this Agreement, less the aggregate amount of any damages that such
Underwriter has otherwise been required to pay in respect of the same or any
substantially similar claim, and no person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation. The Underwriters' obligations to contribute hereunder are
several in proportion to their respective underwriting obligations and not
joint, and contributions among Underwriters shall be governed by the provisions
of the Prudential Securities Incorporated Master Agreement Among Underwriters.
For purposes of this paragraph (d), each person, if any, who controls an
Underwriter within the meaning of Section 15 of the Act or Section 20 of the
Exchange Act shall have the same rights to contribution as such Underwriter, and
each director of the Company, each officer of the Company who signed the
Registration Statement and each person, if any, who controls the Company within
the meaning of Section 15 of the Act or Section 20 of the Exchange Act, shall
have the same rights to contribution as the Company.

                                      24.
<PAGE>

     9.   Default of Underwriters.  If one or more Underwriters default in their
          -----------------------
obligations to purchase Firm Securities or Option Securities hereunder and the
aggregate number of such Securities that such defaulting Underwriter or
Underwriters agreed but failed to purchase is ten percent or less of the
aggregate number of Firm Securities or Option Securities to be purchased by all
of the Underwriters at such time hereunder, the other Underwriters may make
arrangements satisfactory to the Representatives for the purchase of such
Securities by other persons (who may include one or more of the non-defaulting
Underwriters, including the Representatives), but if no such arrangements are
made by the Firm Closing Date or the related Option Closing Date, as the case
may be, the other Underwriters shall be obligated severally in proportion to
their respective commitments hereunder to purchase the Firm Securities or Option
Securities that such defaulting Underwriter or Underwriters agreed but failed to
purchase.  If one or more Underwriters so default with respect to an aggregate
number of Securities that is more than ten percent of the aggregate number of
Firm Securities or Option Securities, as the case may be, to be purchased by all
of the Underwriters at such time hereunder, and if arrangements satisfactory to
the Representatives are not made within 36 hours after such default for the
purchase by other persons (who may include one or more of the non-defaulting
Underwriters, including the Representatives) of the Securities with respect to
which such default occurs, this Agreement will terminate without liability on
the part of any non-defaulting Underwriter or the Company other than as provided
in Section 10 hereof.  In the event of any default by one or more Underwriters
as described in this Section 9, the Representatives shall have the right to
postpone the Firm Closing Date or the Option Closing Date, as the case may be,
established as provided in Section 3 hereof for not more than seven business
days in order that any necessary changes may be made in the arrangements or
documents for the purchase and delivery of the Firm Securities or Option
Securities, as the case may be.  As used in this Agreement, the term
"Underwriter" includes any person substituted for an Underwriter under this
Section 9. Nothing herein shall relieve any defaulting Underwriter from
liability for its default.

     10.  Survival.  The respective representations, warranties, agreements,
          --------
covenants, indemnities and other statements of the Company, its officers and the
several Underwriters set forth in this Agreement or made by or on behalf of
them, respectively, pursuant to this Agreement shall remain in full force and
effect, regardless of (i) any investigation made by or on behalf of the Company,
any of its officers or directors, any Underwriter or any controlling person
referred to in Section 8 hereof and (ii) delivery of and payment for the
Securities.  The respective agreements, covenants, indemnities and other
statements set forth in Sections 6 and 8 hereof shall remain in full force and
effect, regardless of any termination or cancellation of this Agreement.

     11.  Termination.
          -----------

          (a)     This Agreement may be terminated with respect to the Firm
Securities or any Option Securities in the sole discretion of the
Representatives by notice to the Company given prior to the Firm Closing Date or
the related Option Closing Date, respectively, in the event that the Company
shall have failed, refused or been unable to perform all obligations and satisfy
all conditions on its part to be performed or satisfied hereunder at or prior
thereto or, if at or prior to the Firm Closing Date or such Option Closing Date,
respectively,

                                      25.
<PAGE>

                  (i)    the Company has, in the sole judgment of the
Representatives, sustained any loss or interference with its businesses or
properties that has had a Material Adverse Effect from fire, flood, hurricane,
accident or other calamity, whether or not covered by insurance, or from any
labor dispute or any legal or governmental proceeding or there shall have been
any Material Adverse Effect, or any development involving a prospective Material
Adverse Effect (including without limitation a change in management or control
of the Company), except in each case as described in or contemplated by the
Prospectus (exclusive of any amendment or supplement thereto);

                  (ii)   trading in the Common Stock shall have been suspended
by the Commission or the Nasdaq National Market or trading in securities
generally on the New York Stock Exchange or Nasdaq National Market shall have
been suspended or minimum or maximum prices shall have been established on
either such exchange;

                  (iii)   a banking moratorium shall have been declared by New
York or United States authorities; or

                  (iv)   there shall have been (A) an outbreak or escalation of
hostilities between the United States and any foreign power, (B) an outbreak or
escalation of any other insurrection or armed conflict involving the United
States or (C) any other calamity or crisis or material adverse change in general
economic, political or financial conditions having an effect on the U.S.
financial markets that, in the sole judgment of the Representatives, makes it
impractical or inadvisable to proceed with the public offering or the delivery
of the Securities as contemplated by the Registration Statement, as amended as
of the date hereof.

          (b)     Termination of this Agreement pursuant to this Section 11
shall be without liability of any party to any other party except as provided in
Section 10 hereof.

     12.  Information Supplied by Underwriters.  The information set forth in
          ------------------------------------
the last paragraph on the front cover page (insofar as such information relates
to the underwriters) and the information as set forth under the heading
"Underwriting" in any Preliminary Prospectus or the Prospectus (to the extent
such statements relate to the Underwriters) constitute the only information
furnished by any Underwriter through the Representatives to the Company for the
purposes of Sections 2(b) and 8 hereof. The Underwriters confirm that such
statements (to such extent) are correct.

     13.  Notices.  All communications hereunder shall be in writing and, if
          -------
sent to any of the Underwriters, shall be delivered or sent by mail, telex or
facsimile transmission and confirmed in writing to Prudential Securities
Incorporated, One New York Plaza, New York, New York 10292, Attention: Equity
Transactions Group; and if sent to the Company, shall be delivered or sent by
mail, telex or facsimile transmission and confirmed in writing to the Company at
55 Green Mountain Drive, South Burlington, Vermont 05403.

     14.  Successors.  This Agreement shall inure to the benefit of and shall be
          ----------
binding upon the several Underwriters, the Company and their respective
successors and legal representatives, and nothing expressed or mentioned in this
Agreement is intended or shall be construed to give any other person any legal
or equitable right, remedy or claim under or in

                                      26.
<PAGE>

respect of this Agreement, or any provisions herein contained, this Agreement
and all conditions and provisions hereof being intended to be and being for the
sole and exclusive benefit of such persons and for the benefit of no other
person except that (i) the indemnities of the Company contained in Section 8 of
this Agreement shall also be for the benefit of any person or persons who
control any Underwriter within the meaning of Section 15 of the Act or Section
20 of the Exchange Act and (ii) the indemnities of the Underwriters contained in
Section 8 of this Agreement shall also be for the benefit of the directors of
the Company, the officers of the Company who have signed the Registration
Statement and any person or persons who control the Company within the meaning
of Section 15 of the Act or Section 20 of the Exchange Act. No purchaser of
Securities from any Underwriter shall be deemed a successor because of such
purchase.

     15.  Applicable Law.  The validity and interpretation of this Agreement,
          --------------
and the terms and conditions set forth herein, shall be governed by and
construed in accordance with the laws of the State of New York, without giving
effect to any provisions relating to conflicts of laws.

     16.  Consent to Jurisdiction and Service of Process.  All judicial
          ----------------------------------------------
proceedings arising out of or relating to this Agreement may be brought in any
state or federal court of competent jurisdiction in the State of New York, and
by execution and delivery of this Agreement, the Company accepts for itself and
in connection with its properties, generally and unconditionally, the
nonexclusion jurisdiction of the aforesaid courts and waives any defense of
forum non conveniens and irrevocably agrees to be bound by any judgment rendered
thereby in connection with this Agreement. The Company designates and appoints
CT Corporation System, 1633 Broadway, New York, New York, and such other persons
as may hereafter be selected by the Company irrevocably agreeing in writing to
so serve, as its agent to receive on its behalf service of all process in any
such proceedings in any such court, such service being hereby acknowledged by
the Company to be effective and binding service in every respect. A copy of any
such process so served shall be mailed by registered mail to Prudential
Securities Incorporated at its address provided in Section 13 hereof; provided,
                                                                      --------
however, that, unless otherwise provided by applicable law, any failure to mail
- -------
such copy shall not affect the validity of service of such process.  If any
agent appointed by the Company refuses to accept service, the Company hereby
agrees that service of process sufficient for personal jurisdiction in any
action against the Company in the State of New York may be made by registered or
certified mail, return receipt requested, to the Company at its address provided
in Section 13 hereof, and the Company hereby acknowledges that such service
shall be effective and binding in every respect.  Nothing herein shall affect
the right to serve process in any other manner permitted by law or shall limit
the right of any Underwriter to bring proceedings against the Company in the
courts of any other jurisdiction.

     17.  Counterparts.  This Agreement may be executed in two or more
          ------------
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

                                      27.

                      II.  Effect of Merger on Securities
                           ------------------------------

     2.1  Conversion of Units.  At the Effective Time, each common unit in the
          -------------------
LLC (each, a "Unit") outstanding immediately prior to the Effective Time shall,
by virtue of the Merger and without any action on the part of the holder
thereof, be converted into the right to receive 3.0 shares of fully paid and
nonassessable common stock, par value $0.01 per share, of the Corporation
("Common Stock") upon surrender of the certificate formerly representing such
Unit in accordance with this Agreement.

     2.2  Options to Purchase Units.  At the Effective Time, each then-
          -------------------------
outstanding option to purchase Units (each, an "Option"), whether or not then
exercisable or fully vested, shall be assumed by the Corporation and shall
constitute an option to acquire, on substantially the same terms and subject to
substantially the same conditions as were applicable under such Option
immediately prior to the Effective Time, the number of shares of Common Stock,
determined by multiplying the number of Units subject to such Option immediately
prior to the Effective Time by 3.0 (the "Conversion Factor"), at an exercise
price per share of Common Stock (rounded to the nearest whole cent) equal to the
exercise price per Unit of Units subject to such Option divided by the
Conversion Factor.

     2.3  Warrants to Purchase Units.  From and after the Effective Time, the
          --------------------------
holder of any warrant to purchase Units outstanding at the Effective Time (each,
a "Warrant") shall have the right until the expiration date thereof to exercise
such Warrant for the number of whole shares of

                                       2
<PAGE>

Common Stock receivable pursuant to Section 2.1 hereof by a holder of the number
of Units for which such Warrant might have been exercised immediately prior to
the Effective Time.

     2.4  No Shares of the Corporation Outstanding.  There will be no shares of
          ----------------------------------------
stock of the Corporation outstanding immediately prior to the Effective Time.

                        III.  Exchange of Certificates
                              ------------------------

     3.1  Letters of Transmittal; Surrender of Certificates.  The Corporation
          -------------------------------------------------
shall provide to each holder of record of a certificate or certificates that,
immediately prior to the Effective Time, evidenced outstanding Units (the
"Certificates") a form of letter of transmittal (which shall specify that
delivery shall be effected, and risk of loss and title to the Certificates shall
pass, only upon proper delivery of the Certificates to the Corporation, and
shall be in such form and have such other provisions as the Corporation may
specify), together with related instructions, for use in effecting the surrender
of the Certificates in exchange for shares of Common Stock as contemplated by
Section 2.1 hereof. Upon surrender of a Certificate for cancellation to the
Corporation (or an exchange agent designated by the Corporation), together with
a duly executed letter of transmittal and such other customary documents as may
be required pursuant to such instructions, the holder of such Certificate shall
be entitled to receive in exchange therefor a certificate representing the
number of shares of Common Stock that the aggregate number of Units previously
represented by such Certificate shall have been converted into the right to
receive pursuant to Section 2.1 hereof, and the Certificate so surrendered shall
forthwith be canceled.

     3.2  Cancellation of Units; No Further Rights.  As of the Effective Time,
          ----------------------------------------
all Units issued and outstanding immediately prior to the Effective Time shall
cease to be outstanding, shall automatically be canceled and shall cease to
exist, and each holder of a Certificate theretofore representing any such Units
shall cease to have any rights with respect thereto, except the right to receive
shares of Common Stock upon surrender of such Certificate in accordance with
Section 3.1 hereof, and until so surrendered, each such Certificate shall
represent for all purposes only the right to receive shares of Common Stock as
provided in this Agreement. The shares of Common Stock delivered upon the
surrender for exchange of Certificates in accordance with the terms of this
Article III shall be deemed to have been delivered in full satisfaction of all
rights pertaining to the Units theretofore represented by such Certificates.

     3.3  Distributions with Respect to Unexchanged Units.  No dividends or
          -----------------------------------------------
other distributions with respect to Common Stock with a record date after the
Effective Time shall be paid to the holder of any unsurrendered Certificate with
respect to the shares of Common Stock issuable upon the surrender of such
Certificate pursuant to Section 3.1, until the surrender of such Certificate
pursuant to Section 3.1. Subject to the effect of applicable escheat or similar
laws, following the surrender of any such Certificate pursuant to Section 3.1
there shall be paid to the holder of the certificate representing the shares of
Common Stock issued in

                                       3
<PAGE>

exchange therefor, without interest, (a) at the time of such surrender, the
amount of dividends or other distributions with respect to such shares of Common
Stock with a record date after the Effective Time that would have been paid with
respect to such shares of Common Stock had those shares been issued and
outstanding as of such record date, and (b) at the appropriate payment date, the
amount of dividends or other distributions with respect to such shares of Common
Stock with a record date after the Effective Time but prior to such surrender
and with a payment date subsequent to such surrender that would have been
payable with respect to such shares of Common Stock had those shares been issued
and outstanding as of such record date.

                              IV.  Miscellaneous

     4.1  Termination.  This Agreement may be terminated at any time prior to
          -----------
the Effective Time by mutual agreement of the LLC and the Corporation,
notwithstanding any prior approvals.

     4.2  Registration Rights Agreement.  At or prior to the Effective Time, the
          -----------------------------
Corporation shall execute a Registration Rights Agreement in such form as the
Corporation may determine, pursuant to which each holder of record of
Certificates, upon such holder's surrender thereof in accordance with Section
3.1, shall be entitled to "piggyback" registration rights with respect to Common
Stock.

                                   ARTICLE V

     The Board may make, amend and repeal the Bylaws of the Company.  Any Bylaw

Notwithstanding the foregoing and anything contained in this Amended and
Restated Certificate of Incorporation to the contrary, Bylaws 1, 3, 8, 10, 11,

                                  ARTICLE VI

     Subject to the rights of the holders of any series of Preferred Stock:

     (a)  any action required or permitted to be taken by the stockholders of
          the Company must be effected at a duly called annual or special
          meeting of stockholders of the Company and may not be effected by any
          consent in writing of the stockholders; and

     (b)  special meetings of the stockholders of the Company may be called only
          by (i) the Chairman of the Board (the "Chairman"), (ii) a Vice
          Chairman of the Board, (iii) the Secretary of the Company within ten
          calendar days after receipt of a written request of a majority of the
          total number of Directors that the Company would have if there were no
          vacancies (the "Whole Board"), or (iv) as otherwise provided in a
          Preferred Stock Designation.

At any annual meeting or special meeting of the stockholders of the Company,
only such business will be conducted or considered as has been brought before
such meeting in the manner provided in the Bylaws of the Company.
Notwithstanding anything contained in this Amended and  Restated Certificate of
Incorporation to the contrary, the affirmative vote of the holders of record of
at least 80% of the Voting Stock, voting together as a single class, is required
to amend or repeal, or to adopt any provision inconsistent with, this Article
VI.

                                  ARTICLE VII

     Section 1.  Number, Election and Terms of Directors.  Subject to the
                 ---------------------------------------
rights, if any, of the holders of any series of Preferred Stock to elect
additional Directors under circumstances specified in a Preferred Stock
Designation, the number of the Directors of the Company will not be less than
three nor more than 15 and will be fixed from time to time in the manner
described in the Bylaws of the Company.  The Directors, other than those who may
be elected by the holders of any series of Preferred Stock, will be classified
with respect to the time for which they severally hold office into three
classes, as nearly equal in number as possible, designated Class I, Class II and
Class III.  The Directors first appointed to Class I will hold office for a term
expiring at the annual meeting of stockholders to be held in 2000; the Directors
first appointed to Class II will hold office for a term expiring at the annual
meeting of stockholders to be held in 2001; and the Directors first appointed to
Class III will hold office for a term expiring at the annual meeting of
stockholders to be held in 2002.  The members of each class will hold office
until their successors are elected and qualified or until their earlier
resignation or removal.  At each succeeding annual meeting of the stockholders
of the Company, the successors of the class of Directors whose terms expire at
that meeting will be elected by plurality vote of all votes cast at such meeting
to hold office for a term expiring at the annual meeting of stockholders held in
the third year following the year of their election.  Subject to the rights, if
any, of the holders of any series of Preferred Stock to elect additional
Directors under circumstances specified in a Preferred Stock Designation,
Directors may be elected by the stockholders only at an annual meeting of
stockholders.  Election of Directors of the Company need not be by written
ballot unless requested by the Chairman or by

                                      -3-
<PAGE>

the holders of a majority of the Voting Stock present in person or represented
by proxy at a meeting of the stockholders at which Directors are to be elected.

     Section 2.  Nomination of Director Candidates.  Advance notice of
                 ---------------------------------
stockholder nominations for the election of Directors must be given in the
manner provided in the Bylaws of the Company.

     Section 3.  Newly Created Directorships and Vacancies.  Subject to the
                 -----------------------------------------
rights, if any, of the holders of any series of Preferred Stock to elect
additional Directors under circumstances specified in a Preferred Stock
Designation, newly created directorships resulting from any increase in the
number of Directors and any vacancies on the Board resulting from death,
resignation, disqualification, removal or other cause will be filled solely by
the affirmative vote of a majority of the remaining Directors then in office,
even though less than a quorum of the Board, or by a sole remaining Director, or
if there is no remaining Director, by the stockholders of the Company.  Any
Director elected in accordance with the preceding sentence will hold office for
the remainder of the full term of the class of Directors in which the new
directorship was created or the vacancy occurred and until such Director's
successor has been elected and qualified.  No decrease in the number of
Directors constituting the Board may shorten the term of any incumbent Director.

     Section 4.  Removal.  Subject to the rights, if any, of the holders of any
                 -------
series of Preferred Stock to elect additional Directors under circumstances
specified in a Preferred Stock Designation, any Director may be removed from
office by the stockholders only for cause and only in the manner provided in
this Section 4.  At any annual or special meeting of the stockholders, the
notice of which states that the removal of a Director or Directors is among the
purposes of the meeting, the affirmative vote of the holders of at least 80% of
the Voting Stock, voting together as a single class, may remove such Director or
Directors for cause.

     Section 5.  Amendment, Repeal, Etc.  Notwithstanding anything contained in
                 -----------------------
this Amended and Restated Certificate of Incorporation to the contrary, the
affirmative vote of at least 80% of the Voting Stock, voting together as a
single class, is required to amend or repeal, or to adopt any provision
inconsistent with, this Article VII.

                                 ARTICLE VIII

     To the fullest extent permitted by the DGCL or any other applicable law
currently or hereafter in effect, no Director of the Company will be personally
liable to the Company or its stockholders for or with respect to any acts or
omissions in the performance of his or her duties as a Director of the Company.
Any repeal or modification of this Article VIII will not adversely affect any
right or protection of a Director of the Company in respect of any act or
omission occurring in whole or in part prior to such repeal or modification.

                                      -4-
<PAGE>

                                  ARTICLE IX

     The Company will to the fullest extent permitted by applicable law as then
in effect indemnify any person who was or is a party or is threatened to be made
a party to any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative and whether brought by
or in the right of the Company or otherwise, by reason of the fact that such
person is or was a director or officer of the Company, or is or was a director
or officer of the Company and is or was serving at the request of the Company as
a director, officer, employee or agent of another corporation, partnership,
joint venture, trust, employee benefit plan or other enterprise, against all
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by such person in connection with
such action, suit or proceeding.  The right to indemnification shall extend to
the heirs, executors, administrators and estate of any such director or officer.
The right to indemnification provided in this Article IX:  (a) will not be
exclusive of any other rights to which any person seeking indemnification may
otherwise be entitled, including without limitation, pursuant to any contract
approved by a majority of the Whole Board (whether or not the Directors
approving such contract are or are to be parties to such contract or similar
contracts); and (b) will be applicable to matters otherwise within its scope
whether or not such matters arose or arise before or after the adoption of this
Article IX.  Without limiting the generality or the effect of the foregoing, the
Company may adopt Bylaws, or enter into one or more agreements with any person,
that provide for indemnification greater or otherwise different than that
provided in this Article IX or the DGCL, and any such agreement approved by a
majority of the Whole Board will be a valid and binding obligation of the
Company regardless of whether one or more members of the Board, or all members
of the Board, are parties thereto or to similar agreements.  Notwithstanding
anything to the contrary in this Article IX, in the event that the Company
enters into a contract with any person providing for indemnification of such
person, the provisions of that contract will exclusively govern the Company's
obligations in respect of indemnification for or advancement of fees or
disbursements of that person's counsel or any other professional engaged by that
person.  Any amendment or repeal of, or adoption of any provision inconsistent
with, this Article IX will not adversely affect any right or protection existing
hereunder, or arising out of events occurring or circumstances existing, in
whole or in part, prior to such amendment, repeal or adoption, and no such
amendment, repeal or adoption will affect the legality, validity or
enforceability of any contract entered into or right granted prior to the
effective date of such amendment, repeal or adoption.

                           MEETINGS OF STOCKHOLDERS


      Section 1.  Time and Place of Meetings.  All meetings of the stockholders
for the election of directors or for any other purpose shall be held at such
time and place, within or without the State of Delaware, as may be designated by
the Board of Directors, or by the Chairman of the Board, the President or the
Secretary in the absence of a designation by the Board of Directors, and stated
in the notice of the meeting or in a duly executed waiver of notice thereof.

      Section 2.  Annual Meeting.  An annual meeting of the stockholders,
commencing with the year 2000, shall be held on such date and at such time as
shall be designated from time to time by the Board of Directors, at which
meeting the stockholders shall elect by a plurality vote the directors to
succeed those whose terms expire and shall transact such other business as may
properly be brought before the meeting.

      Section 3.  Special Meetings.  Special meetings of the stockholders, for
any purpose or purposes, unless otherwise prescribed by law or by Certificate of
Incorporation, may be called by the Board of Directors.

      Section 4.  Notice of Meetings.  Written notice of every meeting of the
stockholders, stating the place, date and hour of the meeting and, in the case
of a special meeting, the purpose or purposes for which the meeting is called,
shall be given not less than ten nor more than sixty days before the date of the
meeting to each stockholder entitled to vote at such meeting, except as
otherwise provided herein or by law.
<PAGE>

      Section 5.  Quorum.  The holders of a majority of the stock issued and
outstanding and entitled to vote thereat, present in person or represented by
proxy, shall constitute a quorum at all meetings of the stockholders for the
transaction of business except as otherwise provided by law or by the
Certificate of Incorporation.  If, however, such quorum shall not be present or
represented at any meeting of the stockholders, the stockholders entitled to
vote thereat, present in person or represented by proxy, shall have power to
adjourn the meeting from time to time, without notice other than announcement at
the meeting, until a quorum shall be present or represented.

      Section 6.  Voting.  Except as otherwise provided by law or by the
Certificate of Incorporation, each stockholder shall be entitled at every
meeting of the stockholders to one vote for each share of stock having voting
power standing in the name of such stockholder on the books of the Corporation
on the record date for the meeting and such votes may be cast either in person
or by written proxy.  Every proxy must be duly executed and filed with the
Secretary of the Corporation.  A stockholder may revoke any proxy which is not
irrevocable by attending the meeting and voting in person or by filing an
instrument in writing revoking the proxy or another duly executed proxy bearing
a later date with the Secretary of the Corporation.  The vote upon any question
brought before a meeting of the stockholders may be by voice vote, unless the
holders of a majority of the outstanding shares of all classes of stock entitled
to vote thereon present in person or by proxy at such meeting shall so
determine.  Every vote taken by written ballot shall be counted by one or more
inspectors of election appointed by the Board of Directors.  When a quorum is
present at any meeting, the vote of the holders of a majority of the stock which
has voting power present in person or represented by proxy shall decide any
question properly brought before such meeting, unless the question is one upon
which by express


                                      -2-
<PAGE>

provision of law, the Certificate of Incorporation or these bylaws, a different
vote is required, in which case such express provision shall govern and control
the decision of such question.

                                   DIRECTORS

      Section 1.  Powers.  The business and affairs of the Corporation shall be

not by law or by the Certificate of Incorporation directed or required to be
exercised or done by the stockholders.

meeting or a special meeting.  The directors shall be elected at the annual
meeting of the stockholders, except as provided in Section 3 of this Article,
and each director elected shall hold office until his successor is elected and
qualified, except as required by law.  Any decrease in the authorized number of

directors then in office, unless, at the time of such decrease, there shall be
vacancies on the Board which are being eliminated by such decrease.

      Section 3.  Vacancies and New Directorships.  Vacancies and newly created
directorships resulting from any increase in the authorized number of directors
which occur between annual meetings of the stockholders may be filled by a
majority of the directors then in office, though less than a quorum, or by a
sole remaining director, and the directors so elected shall hold office until
the next annual meeting of the stockholders and until their successors are
elected and qualified, except as required by law.

may be called by the Chairman of the Board or the President on one day's written
notice to each director by whom such notice is not waived, given either
personally or by mail, facsimile or telegram, and shall be called by the
President or the Secretary.

      Section 6.  Quorum.  At all meetings of the Board of Directors, a majority
of the total number of directors then in office shall constitute a quorum for
the transaction of business, and the act of a majority of the directors present

Directors.  If a quorum shall not be present at any meeting of the Board of
Directors, the directors present thereat may adjourn the meeting from time to
time to another place, time or date, without notice other than announcement at
the meeting, until a quorum shall be present.

      Section 7.  Written Action.  Any action required or permitted to be taken

      Section 9.  Committees.  The Board of Directors may, by resolution passed
by a majority of the whole Board, designate one or more committees, each
committee to consist of one or more of the directors of the Corporation and each
to have such lawfully delegable powers and duties as the Board may confer.  Each
such committee shall serve at the pleasure of the Board of Directors. The Board
may designate one or more directors as alternate members of any committee, who
may replace any absent or disqualified member at any meeting of the committee.
Except as otherwise provided by law, any such committee, to the extent provided
in the resolution of the Board of Directors, shall have and may exercise all the
powers and authority of the Board of Directors in the management of the business
and affairs of the Corporation, and may authorize the seal of the Corporation to
be affixed to all papers which may require it.  Any committee or committees so
designated by the Board shall have such name or names as may be determined from
time to time by resolution adopted by the Board of Directors.  Unless otherwise
prescribed by the Board of Directors, a majority of the members of the committee
shall constitute a quorum for the transaction of business, and the act of a
majority of the members present at a meeting at which there is a quorum shall be
the act of such committee.  Each committee shall prescribe its own rules for
calling and holding meetings and its method of procedure, subject to any rules
prescribed by the Board of Directors, and shall keep a written record of all
actions taken by it.

      Section 10.  Compensation.  The Board of Directors may establish such
compensation for, and reimbursement of the expenses of, directors for attendance
at meetings of the Board of Directors or committees, or for other services by
directors to the Corporation, as the Board of Directors may determine.

Certificate of Incorporation or these bylaws, notice is required to be given to
any director or stockholder, it shall not be construed to mean personal notice,

waiver thereof in writing, signed by the person or persons entitled to such

given, shall be deemed equivalent to such notice.  Attendance of a person at a
meeting shall constitute a waiver of notice of such meeting, except when the
person attends a meeting for the express purpose of objecting, at the beginning
of the meeting, to the transaction of any business because the meeting is not
lawfully called or convened.

the Corporation.

possess by reason of its ownership of securities of such other corporation. In
addition, the President may delegate to other officers, employees and agents of
the Corporation the power and authority to take any action which the President
is authorized to take under this Section 5, with such limitations as the
President may specify; such authority so delegated by the President shall not be
re-delegated by the person to whom such execution authority has been delegated.

                                   ARTICLE V

<PAGE>

by the Corporation alleged to have been lost, stolen or destroyed upon the
making of an affidavit of that fact, satisfactory to the Secretary, by the
person claiming the certificate of stock to be lost, stolen or destroyed. As a
condition precedent to the issuance of a new certificate or certificates the
Secretary may require the owner of such lost, stolen or destroyed certificate or
certificates to give the Corporation a bond in such sum and with such surety or
sureties as the Secretary may direct as indemnity against any claims that may be
made against the Corporation with respect to the certificate alleged to have
been lost, stolen or destroyed or the issuance of the new certificate.

                                  ARTICLE VI

such information, opinions, reports or statements presented to the Corporation
by any of the Corporation's officers or employees, or committees of the Board of
Directors, or by any other person as to matters the director, committee member

competence and who has been selected with reasonable care by or on behalf of the

                            STOCKHOLDERS' MEETINGS


      1.  Time and Place of Meetings.  All meetings of the stockholders for the
          --------------------------
election of directors or for any other purpose will be held at such time and
place, within or without the State of Delaware, as may be designated by the
Board of Directors ("Board") or, in the absence of a designation by the Board,
the Chairman, a Vice Chairman or the Chief Executive Officer, and stated in the
notice of meeting.  The Board, the Chairman or a Vice Chairman may postpone any
previously scheduled annual or special meeting of the stockholders.

      2.  Annual Meeting.  An annual meeting of the stockholders will be held at
          --------------
such date and time as may be designated from time to time by the Board, at which
meeting the stockholders will elect, by a plurality vote of the Voting Stock of
the stockholders present in person or represented by proxy, the directors to
succeed those whose terms expire and will transact such other business as may
properly be brought before the meeting in accordance with these Bylaws.  For
purposes of these Bylaws, the term "Voting Stock" means the capital stock of the
Company of any class or series entitled to vote generally in the election of
directors.

      3.  Special Meetings.  Special meetings of the stockholders, for any
          ----------------
purpose or purposes, unless otherwise prescribed by law or by the certificate of
incorporation of the Company, as amended from time to time (the "Certificate of
Incorporation"), may be called only by (a) the Chairman, (b) a Vice Chairman,
(c) the Secretary within 10 calendar days after receipt of a written request of
a majority of the total number of directors that the Company would have if there
were no vacancies (the "Whole Board"), or (d) as otherwise provided in a
Preferred Stock Designation.  Any such request by a majority of the Whole Board
must be sent to the Chairman and the Secretary and must state the purpose or
purposes of the proposed meeting.  Special meetings of holders of the
outstanding Preferred Stock, if any, may be called in the manner and for the
purposes provided in the applicable Preferred Stock Designation.

      4.  Notice of Meetings.  Written notice of every meeting of the
          ------------------
stockholders, stating the place, date and hour of the meeting and, in the case
of a special meeting, the purpose or purposes for which the meeting is called,
will be given not less than 10 nor more than 60 calendar days before the date of
the meeting to each stockholder of record entitled to vote at such meeting,
except as otherwise provided in these Bylaws or by law.  When a meeting is
adjourned to another place, date or time, written notice need not be given of
the adjourned meeting if the place, date and time thereof are announced at the
meeting at which the adjournment is taken; provided, however, that if the
adjournment is for more than 30 calendar days, or if after the adjournment a new
record date is fixed for the adjourned meeting, written notice of the place,
date and time of the adjourned meeting must be given in conformity with these
Bylaws.  At any adjourned meeting, any business may be transacted which might
have been transacted at the original meeting.

      5.  Inspectors.  The Board may appoint one or more inspectors of election
          ----------
to act as judges of the voting and to determine those entitled to vote at any
meeting of the stockholders, or any adjournment thereof, in advance of the
meeting.  The Board may designate one or more persons as alternate inspectors to
replace any inspector who fails to act.  If no inspector or

                                       1
<PAGE>

alternate is able to act at a meeting of stockholders, the presiding officer of
the meeting may appoint one or more substitute inspectors.

      6.  Quorum.  Except as otherwise provided by law or in a Preferred Stock
          ------
Designation, the holders of a majority of the stock issued and outstanding and
entitled to vote at a meeting of stockholders, present in person or represented
by proxy, will constitute a quorum at all meetings of the stockholders for the
transaction of business at a meeting of the stockholders. If, however, such
quorum is not present or represented at any meeting of the stockholders, the
stockholders entitled to vote at that meeting of stockholders, present in person
or represented by proxy, will have the power to adjourn, without notice other
than announcement at the meeting, the meeting from time to time until a quorum
is present or represented.

      7.  Voting.  Except as otherwise provided by law or in a Preferred Stock
          ------
Designation, each stockholder will be entitled at every meeting of the
stockholders to one vote for each share of stock having voting power standing in
the name of that stockholder on the books of the Company on the record date for
the meeting and those votes may be cast either in person or by written proxy.
Every proxy must be duly executed and filed with the Secretary.  A stockholder
may revoke any proxy that is not irrevocable by attending the meeting and voting
in person or by filing an instrument in writing revoking the proxy or another
duly executed proxy bearing a later date with the Secretary.  The vote upon any
question brought before a meeting of the stockholders may be by voice vote,
unless otherwise required by these Bylaws or unless the presiding officer of the
meeting or the holders of a majority of the outstanding shares of all classes of
stock entitled to vote on that question present in person or by proxy at the
meeting otherwise determine.  Every vote taken by written ballot will be counted
by the inspectors of election.  When a quorum is present at any meeting, the
vote of the holders of a majority of the stock which has voting power present in
person or represented by proxy and which has actually voted will decide any
question properly brought before such meeting, unless the question is one upon
which by express provision of law, the Certificate of Incorporation, a Preferred
Stock Designation or these Bylaws, a different vote is required, in which case
that express provision will govern and control the decision of such question.

      8.  Order of Business.  (a) The Chairman, or such other officer of the
          -----------------
Company designated by a majority of the Whole Board, will call meetings of the
stockholders to order and will act as presiding officer thereof.  Except as
otherwise provided by law or in a Preferred Stock Designation or unless
otherwise determined by the Board prior to the meeting, the presiding officer of
the meeting of the stockholders will also determine the order of business and
have the authority in his or her sole discretion to regulate the conduct of the
meeting, including without limitation, by imposing restrictions on the persons
(other than stockholders of the Company or their duly appointed proxies) who may
attend any such stockholders' meeting, by ascertaining whether any stockholder
or the stockholder's proxy may be excluded from any meeting of the stockholders
based upon any determination by the presiding officer, in his or her sole
discretion, that any such person has unduly disrupted or is likely to disrupt
the proceedings at the meeting of the stockholders and by determining the
circumstances in which any person may make a statement or ask questions at any
meeting of the stockholders.

                                       2
<PAGE>

      (b) At an annual meeting of the stockholders, only such business will be
conducted or considered as is properly brought before the meeting.  To be
properly brought before an annual meeting, business must be (i) specified in the
notice of meeting (or any supplement thereto) given by or at the direction of
the Chairman or the Board in accordance with these Bylaws, (ii) otherwise
properly brought before the meeting by the presiding officer or by or at the
direction of a majority of the Whole Board, or (iii) otherwise properly
requested to be brought before the meeting by a stockholder of the Company in
accordance with these Bylaws.

      (c) For business to be properly requested by a stockholder to be brought
before an annual meeting, the stockholder must (i) be a stockholder of the
Company of record at the time of the giving of the notice for such annual
meeting provided for in these Bylaws, (ii) be entitled to vote at such meeting,
and (iii) have given timely notice thereof in writing to the Secretary.  To be
timely, a stockholder's notice must be delivered to or mailed and received at
the principal executive offices of the Company not less than 60 nor more than 90
calendar days prior to the anniversary of the date on which the Company first
mailed its proxy materials for the prior year's annual meeting of stockholders;
provided, however, that in the event that (i) there was no annual meeting held
during the prior year or (ii) the annual meeting is called for a date that is
not within 30 calendar days before or after the anniversary of the prior year's
annual meeting, notice by the stockholder in order to be timely must be so
received not later than the close of business on the tenth calendar day
following the day on which public announcement was first made of the date of the
annual meeting.  In no event will the public announcement of an adjournment of
an annual meeting commence a new time period for the giving of a stockholder's
notice as described above. For purposes of the foregoing, the date on which the
Company first mailed its proxy materials to stockholders will be the date so
described in such proxy materials.

      A stockholder's notice to the Secretary must set forth as to each matter
the stockholder proposes to bring before the annual meeting (i) a description in
reasonable detail of the business desired to be brought before the annual
meeting and the reasons for conducting such business at the annual meeting, (ii)
the name and address, as they appear on the Company's books, of the stockholder
proposing such business and the beneficial owner, if any, on whose behalf the
proposal is made, (iii) the class and number of shares of the Company that are
owned beneficially and of record by the stockholder proposing such business and
by the beneficial owner, if any, on whose behalf the proposal is made, and (iv)
any material interest of such stockholder proposing such business and the
beneficial owner, if any, on whose behalf the proposal is made in such business.
Notwithstanding the foregoing provisions of this Bylaw, a stockholder must also
comply with all applicable requirements of the Securities Exchange Act of 1934,
as amended (the "Exchange Act"), and the rules and regulations thereunder with
respect to the matters set forth in this Bylaw.  For purposes of this Bylaw and
Bylaw 13, "public announcement" means disclosure in a press release reported by
the Dow Jones News Service, Associated Press or comparable national news service
or otherwise published by the Company in substantial conformity with its
ordinary practice in a document publicly filed by the Company with the
Securities and Exchange Commission (the "Commission") pursuant to Section 13, 14
or 15(d) of the Exchange Act, or furnished to stockholders.  Nothing in this
Bylaw will be deemed to affect any rights of stockholders to request inclusion
of proposals in the Company's proxy statement pursuant to Rule 14a-8 under the
Exchange Act.

                                       3
<PAGE>

      (d) At a special meeting of stockholders, only such business may be
conducted or considered as is properly brought before the meeting.  To be
properly brought before a special meeting, business must be (i) specified in the
notice of the meeting (or any supplement thereto) given by or at the direction
of the Chairman, a Vice Chairman or a majority of the Whole Board in accordance
with these Bylaws or (ii) otherwise properly brought before the meeting by the
presiding officer or by or at the direction of a majority of the Whole Board.

      (e) The determination of whether any business sought to be brought before
any annual or special meeting of the stockholders is properly brought before
such meeting in accordance with this Bylaw will be made by the presiding officer
of such meeting.  If the presiding officer determines that any business is not
properly brought before such meeting, he or she will so declare to the meeting
and any such business will not be conducted or considered.

          -------------------------
series of Preferred Stock to elect additional directors under circumstances
specified in a Preferred Stock Designation and to the minimum and maximum number
of authorized directors provided in the Certificate of Incorporation, the
authorized number of directors may be determined from time to time by a vote of
a majority of the Whole Board.  The directors, other than those who may be
elected by the holders of any series of the Preferred Stock, will be classified
with respect to the time for which they severally hold office in accordance with
the Certificate of Incorporation.

      11. Vacancies and New Directorships.  Subject to the rights, if any, of
          -------------------------------
the holders of any series of Preferred Stock under a Preferred Stock Designation

any increase in the authorized number of directors and any vacancies on the
Board resulting from death, resignation, disqualification, removal or other
cause will be filled solely by the affirmative vote of a majority of the
remaining directors then in office, even though less than a quorum of the Board,
or by a sole remaining director, or if there is no remaining director, by the
stockholders.  Any director elected in accordance with the preceding sentence
will hold office for the remainder of the full term of the class of directors in
which the new directorship was created or the vacancy occurred and until such
director's successor has been elected and qualified.  No decrease in the number
of directors constituting the Board may shorten the term of any incumbent
director.

      12. Removal.  Subject to the rights, if any, of the holders of any series
          -------
of Preferred Stock to elect additional directors under circumstances specified
in a Preferred Stock Designation, any director may be removed from office by the
stockholders only for cause and only in the manner provided in the Certificate
of Incorporation.

      13. Nominations of Directors; Election.  Subject to the rights, if any, of
          ----------------------------------
the holders of any series of Preferred Stock to elect additional directors under
circumstances specified in a

                                       4
<PAGE>

Preferred Stock Designation, only persons who are nominated in accordance with
the following procedures will be eligible for election at a meeting of
stockholders as directors of the Company.

      (a) Nominations of persons for election as directors of the Company may be
made only at an annual meeting of stockholders (i) by or at the direction of the
Board or (ii) by any stockholder who is a stockholder of record at the time of
giving of notice provided for in this Bylaw, who is entitled to vote for the
election of directors at such meeting and who complies with the procedures set
forth in this Bylaw.  All nominations by stockholders must be made pursuant to
timely notice in proper written form to the Secretary.

      (b) To be timely, a stockholder's notice must be delivered to or mailed
and received at the principal executive offices of the Company not less than 60
nor more than 90 calendar days prior to the anniversary of the date on which the
Company first mailed its proxy materials for the prior year's annual meeting of
stockholders; provided, however, that in the event that (i) there was no annual
meeting held during the prior year or (ii) the annual meeting is called for a
date that is not within 30 calendar days before or after the anniversary of the
prior year's annual meeting, notice by the stockholder in order to be timely
must be so received not later than the close of business on the tenth calendar
day following the day on which public announcement was first made of the date of
the annual meeting. In no event will the public announcement of an adjournment
of an annual meeting commence a new time period for the giving of a
stockholder's notice as described above. For purposes of the foregoing, the date
on which the Company first mailed its proxy materials to stockholders will the
date so described in such proxy materials.

      To be in proper written form, such stockholder's notice must set forth or
include (i) the name and address, as they appear on the Company's books, of the
stockholder giving the notice and of the beneficial owner, if any, on whose
behalf the nomination is made; (ii) a representation that the stockholder giving
the notice is a holder of record of stock of the Company entitled to vote at
such annual meeting and intends to appear in person or by proxy at the annual
meeting to nominate the person or persons specified in the notice; (iii) the
class and number of shares of stock of the Company owned beneficially and of
record by the stockholder giving the notice and by the beneficial owner, if any,
on whose behalf the nomination is made; (iv) a description of all arrangements
or understandings between or among any of (A) the stockholder giving the notice,
(B) the beneficial owner on whose behalf the notice is given, (C) each nominee,
and (D) any other person or persons (naming such person or persons) pursuant to
which the nomination or nominations are to be made by the stockholder giving the
notice; (v) such other information regarding each nominee proposed by the
stockholder giving the notice as would be required to be included in a proxy
statement filed pursuant to the proxy rules of the Commission under the Exchange
Act had the nominee been nominated, or intended to be nominated, by the Board;
and (vi) the signed consent of each nominee to serve as a director of the
Company if so elected.  At the request of the Board, any person nominated by the
Board for election as a director must furnish to the Secretary that information
required to be set forth in a stockholder's notice of nomination which pertains
to the nominee.  The presiding officer of any annual meeting will, if the facts
warrant, determine that a nomination was not made in accordance with the
procedures prescribed by this Bylaw, and if he or she should so determine, he or
she will so declare to the meeting and the defective nomination will be
disregarded.  Notwithstanding the foregoing provisions of this Bylaw, a
stockholder must also comply with all applicable requirements of the

                                       5
<PAGE>

Exchange Act and the rules and regulations thereunder with respect to the
matters set forth in this Bylaw.

      (c) Notwithstanding anything in this Bylaw to the contrary, in the event
that the number of directors to be elected to the Board is increased and there
is no public announcement by the Company naming all of the nominees for director
or specifying the size of the increased Board at least 70 calendar days prior to
the anniversary of the date on which the Company first mailed its proxy
materials for the preceding year's annual meeting of stockholders, a
stockholder's notice required by this Bylaw will also be considered timely, but
only with respect to nominees for any new positions created by such increase, if
it is delivered to or mailed and received at the principal executive offices of
the Company not later than the close of business on the tenth day following the
day on which such public announcement was first made by the Company.

      14. Resignation.  Any director may resign at any time by giving written
          -----------
notice of his resignation to the Chairman or the Secretary.  Any resignation
will be effective upon actual receipt by any such person or, if later, as of the
date and time specified in such written notice.

      15. Regular Meetings.  Regular meetings of the Board may be held
          ----------------
immediately before or after the annual meeting of the stockholders and at such
other time and place as may from time to time be determined by the Board.  Prior
written notice of regular meetings of the Board must be given not less than 24
hours prior to such meeting by mail, overnight courier, facsimile, e-mail or
similar medium.

      16. Special Meetings.  Special meetings of the Board may be called by the
          ----------------
Chairman on 24 hours' notice to each director by whom such notice is not waived,
given either personally or by mail, overnight courier, telephone, facsimile, e-
mail or similar medium of communication, and will be called by the Chairman in
like manner and on like notice on the request of four or more directors. Special
meetings of the Board may be held at such time and place within or without the
State of Delaware as is determined by the Board or specified in the notice of
any such meeting.

      17. Quorum.  At all meetings of the Board, a majority of the total number
          ------
of directors then in office will constitute a quorum for the transaction of
business.  Except for the designation of committees as provided in these Bylaws
and except for actions required by these Bylaws or the Certificate of
Incorporation to be taken by a majority of the Whole Board, the act of a
majority of the directors present at any meeting at which there is a quorum will
be the act of the Board.  If a quorum is not present at any meeting of the
Board, the directors present at the meeting may adjourn the meeting from time to
time to another place, time or date, without notice other than announcement at
the meeting, until a quorum is present.

      18. Written Action.  Any action required or permitted to be taken at any
          --------------
meeting of the Board or of any committee of the Board may be taken without a
meeting if all members of the Board or committee, as the case may be, consent
thereto in writing, and the writing or writings are filed with the minutes or
proceedings of the Board or committee.

      19. Participation in Meetings by Telephone Conference.  Members of the
          -------------------------------------------------
Board, or any committee designated by the Board, may participate in a meeting of
the Board, or any such

                                       6
<PAGE>

committee, by means of telephone conference or similar means by which all
persons participating in the meeting can hear each other, and such participation
in a meeting will constitute presence in person at the meeting.

      20. Committees.  (a) The Board, by resolution passed by a majority of the
          ----------
Whole Board, may designate an executive committee (the "Executive Committee") of
not less than two and not more than four members of the Board, one of whom will
be the Chairman.  The Executive Committee will have and may exercise all of the
authority of the Board in the management of the business and affairs of the
Company, except where action of the full Board is expressly required by the
DGCL, the Certificate of Incorporation or the Bylaws.  Two-thirds of the members
of the Executive Committee will constitute a quorum for the transaction of
business, and the act of two-thirds of the members of the Executive Committee
(which must include the affirmative vote of the Chairman) will constitute the
act of such committee.

      (b) The Board, by resolution passed by a majority of the Board, may
designate one or more additional committees, each such committee to consist of
one or more directors and each to have such lawfully delegable powers and duties
as the Board may confer.

      (c) The Executive Committee and each other committee of the Board will
serve at the pleasure of the Board or as may be specified in any resolution from
time to time adopted by the Board.  The Board may designate one or more
directors as alternate members of any committee, who may replace any absent or
disqualified member at any meeting of the committee.  In lieu of such action by
the Board, in the absence or disqualification of any member of a committee of
the Board, the members thereof present at any meeting of the committee and not
disqualified from voting, whether or not they constitute a quorum, may, by
unanimous action, appoint another member of the Board to act at the meeting in
the place of any absent or disqualified member.

      (d) Except as otherwise provided in these Bylaws or by law, any committee
of the Board, to the extent provided in these Bylaws or, if applicable, in the
resolution of the Board designating a committee, will have and may exercise all
the powers and authority of the Board in the direction of the management of the
business and affairs of the Company.  Any committee designated by the Board will
have such name as may be determined from time to time by resolution adopted by
the Board.  Except as provided in these Bylaws or as otherwise prescribed by the
Board, a majority of the members of any committee of the Board will constitute a
quorum for the transaction of business, and the act of a majority of the members
will be the act of the committee.  Each committee of the Board may prescribe its
own rules for calling and holding meetings and its method of procedure, subject
to any rules prescribed by the Board, and will keep a written record of all
actions taken by it.

      (e) All of the members of any committee the primary responsibilities of
which include (i) reviewing the professional services to be provided by the
Company's independent auditors and the independence of such firm from the
Company's management, reviewing financial statements with management or
independent auditors and/or reviewing internal accounting controls and (ii)
reviewing and approving the compensation of the Company's

                                       7
<PAGE>

executive officers, will be directors who qualify as "outside directors" within
the meaning of Section 162(m) of the Internal Revenue Code of 1986, as in effect
from time to time, and as "non-employee directors" within the meaning of Rule
16b-3 of the Exchange Act. Notwithstanding any provision of the Certificate of
Incorporation or these Bylaws to the contrary, this Bylaw may not be amended or
repealed by the Board, and no provision inconsistent therewith may be adopted by
the Board, without the affirmative vote of the holders of at least a majority of
the Voting Stock present or represented by proxy and entitled to vote at any
annual or special meeting of stockholders at which such vote is to be taken.

      21. Compensation.  The Board may establish such compensation for, and
          ------------
reimbursement of the expenses of, directors for membership on the Board and on
committees of the Board, attendance at meetings of the Board or committees of
the Board, or for other services by directors to the Company or any of its
majority-owned subsidiaries, as the Board may determine.

      22. Rules.  The Board may adopt rules and regulations for the conduct of
          -----
its meetings and the management of the affairs of the Company.

                                    NOTICES

      23. Generally.  Whenever by law or under the provisions of the Certificate
          ---------
of Incorporation or these Bylaws, notice is required to be given to any director
or stockholder, it will not be construed to require personal notice, but such
notice may be given in writing, by mail, addressed to such director or
stockholder, at his, her or its address as it appears on the records of the
Company, with postage thereon prepaid, and such notice will be deemed to be
given at the time when the same is deposited in the United States mail. Notice
to directors may also be given by overnight courier, telephone, facsimile, e-
mail or similar medium of communication or as may otherwise be permitted by
these Bylaws. Notice by overnight courier will be deemed to be given one
business day after being dispatched; notice by telephone will be deemed to be
given when given personally; notice by e-mail will be deemed to be given when
dispatched; and notice by facsimile transmission will be deemed to be given when
receipt is acknowledged.

      24. Waivers.  Whenever any notice is required to be given by law or under
          -------
the provisions of the Certificate of Incorporation or these Bylaws, a waiver
thereof in writing, signed by the person or persons entitled to such notice,
whether before or after the time of the event for which notice is to be given,
will be deemed equivalent to such notice.  Attendance of a person at a meeting
will constitute a waiver of notice of such meeting, except when the person
attends a meeting for the express purpose of objecting, at the beginning of the
meeting, to the transaction of any business because the meeting is not lawfully
called or convened.

                                   OFFICERS

      25. Generally.  The officers of the Company will be elected by the Board
          ---------
and will consist of a Chairman, a Chief Executive Officer, a Chief Financial
Officer, a President, a Secretary and a Treasurer.  The Board may also choose
any one or more Vice Chairmen, Vice Presidents, Assistant Secretaries, Assistant
Treasurers and any such other officers as the Board may from time to time
determine.  Notwithstanding the foregoing, by specific action, the Board may
authorize the Chairman, a Vice Chairman or the Chief Executive Officer to
appoint any person to any office other than Chairman, Vice Chairman, Chief
Executive Officer, President,

                                       8
<PAGE>

Secretary or Treasurer. Any number of offices may be held by the same person.
Any of the offices may be left vacant from time to time as the Board may
determine. In the case of the absence or disability of any officer of the
Company or for any other reason deemed sufficient by a majority of the Board,
the Board may delegate the absent or disabled officer's powers or duties to any
other officer or to any director.

      26. Compensation.  The compensation of all officers and agents of the
          ------------
Company who are also directors of the Company will be fixed by the Board or by a
committee of the Board. The Board may fix, or delegate the power to fix, the
compensation of other officers and agents of the Company to an officer of the
Company.

      27. Succession.  The officers of the Company will hold office until their
          ----------
successors are elected and qualified.  Any officer may be removed at any time
(a) by the affirmative vote of a majority of the Whole Board or (b) with respect
to any officer other than the Chairman, a Vice Chairman or the Chief Executive
Officer, by the Chief Executive Officer.  Any vacancy occurring in any office of
the Company may be filled by the Board as provided in these Bylaws.

      28. Authority and Duties.  Each of the officers of the Company will have
          --------------------
such authority and will perform such duties as are customarily incident to their
respective offices or as may be specified from time to time by the Board or by
the Chairman or a Vice Chairman.

                                     STOCK

      29. Certificates.  Certificates representing shares of stock of the
          ------------
Company will be in such form as is determined by the Board or an authorized
committee thereof, subject to applicable legal requirements. Each certificate
will be numbered and its issuance recorded in the books of the Company and each
certificate will exhibit the holder's name and the number of shares and will be
signed by, or in the name of the Company by, the Chairman, a Vice Chairman, the
Chief Executive Officer, the President or a Vice President and by the Secretary
or an Assistant Secretary or the Treasurer or an Assistant Treasurer, and will
also be signed by, or bear the facsimile signature of, any properly designated
transfer agent of the Company. Any or all of the signatures and the seal of the
Company, if any, upon the certificates may be facsimiles, engraved or printed.
The certificates may be issued and delivered notwithstanding that the person
whose facsimile signature appears thereon may have ceased to be an officer at
the time certificates are issued and delivered.

      30. Classes of Stock.  The designations, preferences and relative
          ----------------
participating, optional or other special rights of the various classes of stock
or series thereof, and the qualifications, limitations or restrictions thereof,
will be set forth in full or summarized on the face or back of the certificates
which the Company issues to represent its stock or, in lieu thereof, such
certificates will set forth the office of the Company from which the holders of
certificates may obtain a copy of such information.

      31. Transfers.  Upon surrender to the Company or the transfer agent of the
          ---------
Company of a certificate for shares duly endorsed or accompanied by proper
evidence of succession, assignment or authority to transfer, it will be the duty
of the Company to issue, or cause its

                                       9
<PAGE>

transfer agent to issue, a new certificate to the person entitled thereto,
cancel the old certificate and record the transaction upon its books.

      32. Lost, Stolen or Destroyed Certificates.  The Secretary may direct a
          --------------------------------------
new certificate or certificates to be issued in place of any certificate or
certificates previously issued by the Company alleged to have been lost, stolen
or destroyed upon the making of an affidavit of that fact, satisfactory to the
Secretary, by the person claiming the certificate of stock to be lost, stolen or
destroyed.  As a condition precedent to the issuance of a new certificate or
certificates, the Secretary may require the owners of such lost, stolen or
destroyed certificate or certificates to give the Company a bond in such sum and
with such surety or sureties as the Secretary may direct as indemnity against
any claims that may be made against the Company with respect to the certificate
alleged to have been lost, stolen or destroyed or the issuance of the new
certificate.

      33. Record Dates.  (a) In order that the Company may determine the
          ------------
stockholders entitled to notice of or to vote at any meeting of stockholders or
any adjournment thereof, the Board may fix a record date, which will not be more
than 60 nor less than 10 calendar days before the date of such meeting.  If no
record date is fixed by the Board, the record date for determining stockholders
entitled to notice of or to vote at a meeting of stockholders will be at the
close of business on the calendar day next preceding the day on which notice is
given, or, if notice is waived, at the close of business on the calendar day
next preceding the day on which the meeting is held.  A determination of
stockholders of record entitled to notice of or to vote at a meeting of the
stockholders will apply to any adjournment of the meeting; provided, however,
that the Board may fix a new record date for the adjourned meeting.

      (b) In order that the Company may determine the stockholders entitled to
receive payment of any dividend or other distribution or allotment of any rights
or the stockholders entitled to exercise any rights in respect of any change,
conversion or exchange of stock, or for the purpose of any other lawful action,
the Board may fix a record date, which record date will not be more than 60
calendar days prior to such action.  If no record date is fixed, the record date
for determining stockholders for any such purpose will be at the close of
business on the calendar day on which the Board adopts the resolution relating
thereto.

      (c) The Company will be entitled to treat the person in whose name any
share of its stock is registered as the owner thereof for all purposes, and will
not be bound to recognize any equitable or other claim to, or interest in, such
share on the part of any other person, whether or not the Company has notice
thereof, except as expressly provided by applicable law.

                                INDEMNIFICATION

      34. Damages and Expenses.  (a) Without limiting the generality or effect
          --------------------
of Article IX of the Certificate of Incorporation, the Company will to the
fullest extent permitted by applicable law as then in effect indemnify any
person (an "Indemnitee") who was or is a party or is threatened to be made a
party to any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative and whether brought by
or in the right of the Company or otherwise (a "Proceeding"), by reason of the
fact that such person is or was a director or officer of the Company, or is or
was a director or officer of the Company and is or

                                      10
<PAGE>

was serving at the request of the Company as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise, against all expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by such person in connection with such Proceeding. Such indemnification
will be a contract right and will include the right to receive payment in
advance of any expenses incurred by an Indemnitee in connection with such
Proceeding, consistent with the provisions of applicable law as then in effect.

      (b) The rights to indemnification and advancement of expenses provided by,
or granted pursuant to, this Bylaw will not be exclusive of any other rights to
which any person seeking indemnification or advancement of expenses may
otherwise be entitled, and will be applicable to Proceedings commenced or
continuing after the adoption of this Bylaw, whether arising from acts or
omissions occurring before or after such adoption.  The rights to
indemnification and advancement of expenses provided by, or granted pursuant to,
this Bylaw will continue as to a person who has ceased to be a director or
officer of the Company and shall inure to the benefit of the heirs, executors,
administrators and estate of such person.

      (c) In furtherance, but not in limitation of the foregoing provisions, the
following procedures, presumptions and remedies will apply with respect to
advancement of expenses and the right to indemnification under this Bylaw:

          (i)    All reasonable expenses incurred by or on behalf of an
      Indemnitee in connection with any Proceeding will be advanced to the
      Indemnitee by the Company within 30 calendar days after the receipt by the
      Company of a statement or statements from the Indemnitee requesting an
      advance or advances from time to time, whether prior to or after final
      disposition of such Proceeding. Such statement or statements will
      reasonably evidence the expenses incurred by the Indemnitee and, if and to
      the extent required by law at the time of such advance, will include or be
      accompanied by an undertaking by or on behalf of the Indemnitee to repay
      such amounts advanced as to which it may ultimately be determined that the
      Indemnitee is not entitled. If such an undertaking is required by law at
      the time of an advance, no security will be required for the undertaking
      and the undertaking will be accepted without reference to the recipient's
      financial ability to make repayment.

          (ii)   To obtain indemnification under this Bylaw, the Indemnitee will
      submit to the Secretary a written request, including such documentation
      supporting the claim as is reasonably available to the Indemnitee and is
      reasonably necessary to determine whether and to what extent the
      Indemnitee is entitled to indemnification (the "Supporting
      Documentation"). The determination of the Indemnitee's entitlement to
      indemnification will be made not less than 60 calendar days after receipt
      by the Company of the written request for indemnification together with
      the Supporting Documentation. The Secretary within 10 days after receipt
      of such a request for indemnification will advise the Board in writing
      that the Indemnitee has requested indemnification. The Indemnitee's
      entitlement to indemnification under this Bylaw will be determined in one
      of the following ways: (A) by a majority vote of the directors who are not
      and were not parties to the Proceeding for which indemnification is
      sought, even though less than a quorum, (B) by a committee

                                      11
<PAGE>

      of such directors designated by majority vote of such directors, even
      though less than a quorum, (C) if there are no such directors, or if such
      directors so direct, by Independent Counsel in a written opinion, or (D)
      by the stockholders. If the determination of entitlement to
      indemnification is to be made by Independent Counsel pursuant to clause
      (C) above, a majority of the directors who are not and were not parties to
      the Proceeding for which indemnification is sought will select the
      Independent Counsel, but only an Independent Counsel to which the
      Indemnitee does not reasonably object.

          (iii)  Except as otherwise expressly provided in this Bylaw, the
      Indemnitee will be presumed to be entitled to indemnification under this
      Bylaw upon submission of a request for indemnification together with the
      Supporting Documentation in accordance with subparagraph (c)(ii) of this
      Bylaw, and thereafter the Company will have the burden of proof to
      overcome that presumption in reaching a contrary determination. In any
      event, if the person or persons empowered under subparagraph (c)(ii) of
      this Bylaw to determine entitlement to indemnification have not been
      appointed or have not made a determination within 60 calendar days after
      receipt by the Company of the request therefor together with the
      Supporting Documentation, the Indemnitee will be deemed to be entitled to
      indemnification and the Indemnitee will be entitled to such
      indemnification unless (A) the Indemnitee misrepresented or failed to
      disclose a material fact in making the request for indemnification or in
      the Supporting Documentation or (B) such indemnification is prohibited by
      law. The termination of any Proceeding described in Bylaw 34(a), or of any
      claim, issue or matter therein, by judgment, order, settlement or
      conviction, or upon a plea of nolo contendere or its equivalent, will not,
      of itself, adversely affect the right of the Indemnitee to indemnification
      or create a presumption that the Indemnitee did not act in good faith and
      in a manner which the Indemnitee reasonably believed to be in or not
      opposed to the best interests of the Company or, with respect to any
      criminal Proceeding, that the Indemnitee had reasonable cause to believe
      that his or her conduct was unlawful.

          (iv)   (A)  In the event that a determination is made pursuant to
      subparagraph (c)(ii) of this Bylaw that the Indemnitee is not entitled to
      indemnification under this Bylaw, (1) the Indemnitee will be entitled to
      seek an adjudication of his entitlement to such indemnification either, at
      the Indemnitee's sole option, in (x) an appropriate court of the State of
      Delaware or any other court of competent jurisdiction or (y) an
      arbitration to be conducted by a single arbitrator pursuant to the rules
      of the American Arbitration Association, (2) any such judicial proceeding
      or arbitration will be de novo and the Indemnitee will not be prejudiced
      by reason of such adverse determination, and (3) in any such judicial
      proceeding or arbitration the Company will have the burden of proving that
      the Indemnitee is not entitled to indemnification under this Bylaw.

                 (B)  If a determination is made or deemed to have been made,
      pursuant to subparagraph (c)(ii) or (iii) of this Bylaw that the
      Indemnitee is entitled to indemnification, the Company will be obligated
      to pay the amounts constituting such indemnification within five business
      days after such determination has been made or deemed to have been made
      and will be conclusively bound by such determination unless (1) the
      Indemnitee misrepresented or failed to disclose a material fact in making
      the

                                      12
<PAGE>

      request for indemnification or in the Supporting Documentation or (2) such
      indemnification is prohibited by law. In the event that advancement of
      expenses is not timely made pursuant to subparagraph (c)(i) of this Bylaw
      or payment of indemnification is not made within five business days after
      a determination of entitlement to indemnification has been made or deemed
      to have been made pursuant to subparagraph (c)(ii) or (iii) of this Bylaw,
      the Indemnitee will be entitled to seek judicial enforcement of the
      Company's obligation to pay to the Indemnitee such advancement of expenses
      or indemnification. Notwithstanding the foregoing, the Company may bring
      an action, in an appropriate court in the State of Delaware or any other
      court of competent jurisdiction, contesting the right of the Indemnitee to
      receive indemnification hereunder due to the occurrence of any event
      described in subclause (1) or (2) of this clause (B) (a "Disqualifying
      Event"); provided, however, that in any such action the Company will have
      the burden of proving the occurrence of such Disqualifying Event.

                 (C)  The Company will be precluded from asserting in any
      judicial proceeding or arbitration commenced pursuant to the provisions of
      this subparagraph (c)(iv) that the procedures and presumptions of this
      Bylaw are not valid, binding and enforceable and will stipulate in any
      such court or before any such arbitrator that the Company is bound by all
      the provisions of this Bylaw.

                 (D)  In the event that the Indemnitee, pursuant to the
      provisions of this subparagraph (c)(iv), seeks a judicial adjudication of,
      or an award in arbitration to, enforce his or her rights under, or to
      recover damages for breach of, this Bylaw, the Indemnitee will be entitled
      to recover from the Company, and will be indemnified by the Company
      against, any expenses actually and reasonably incurred by the Indemnitee
      if the Indemnitee prevails in such judicial adjudication or arbitration.
      If it is determined in such judicial adjudication or arbitration that the
      Indemnitee is entitled to receive part but not all of the indemnification
      or advancement of expenses sought, the expenses incurred by the Indemnitee
      in connection with such judicial adjudication or arbitration will be
      prorated accordingly.

          (v)    For purposes of this paragraph (c), "Independent Counsel" means
      a law firm or a member of a law firm that neither presently is, nor in the
      past five years has been, retained to represent (A) the Company or the
      Indemnitee in any matter material to either such party or (B) any other
      party to the Proceeding giving rise to a claim for indemnification under
      this Bylaw. Notwithstanding the foregoing, the term "Independent Counsel"
      will not include any person who, under the applicable standards of
      professional conduct then prevailing under the law of the State of
      Delaware, would be precluded from representing either the Company or the
      Indemnitee in an action to determine the Indemnitee's rights under this
      Bylaw.

      (d) If any provision or provisions of this Bylaw are held to be invalid,
illegal or unenforceable for any reason whatsoever: (i) the validity, legality
and enforceability of the remaining provisions of this Bylaw (including without
limitation all portions of any paragraph of this Bylaw containing any such
provision held to be invalid, illegal or unenforceable, that are not themselves
invalid, illegal or unenforceable) will not in any way be affected or impaired

                                      13
<PAGE>

thereby and (ii) to the fullest extent possible, the provisions of this Bylaw
(including without limitation all portions of any paragraph of this Bylaw
containing any such provision held to be invalid, illegal or unenforceable, that
are not themselves invalid, illegal or unenforceable) will be construed so as to
give effect to the intent manifested by the provision held invalid, illegal or
unenforceable.

      35. Insurance, Contracts and Funding.  The Company may purchase and
          --------------------------------
maintain insurance to protect itself and any Indemnitee against any expenses,
judgments, fines and amounts paid in settlement or incurred by any Indemnitee in
connection with any Proceeding referred to in Bylaw 34 or otherwise, to the
fullest extent permitted by applicable law as then in effect.  The Company may
enter into contracts with any person entitled to indemnification under Bylaw 34
or otherwise, and may create a trust fund, grant a security interest or use
other means (including without limitation a letter of credit) to ensure the
payment of such amounts as may be necessary to effect indemnification as
provided in Bylaw 34.  Notwithstanding anything to the contrary contained in
Bylaw 34, in the event that the Company enters into a contract with any person
providing for indemnification of such person, the provisions of such contract
will exclusively govern the Company's obligations in respect of indemnification
for or advancement of fees or disbursements of such person's counsel or any
other professional engaged by such person.

                                    GENERAL

          ----------------------------------------
of a committee designated by the Board and each officer of the Company will, in
the performance of his or her duties, be fully protected in relying in good
faith upon the records of the Company and upon such information, opinions,
reports or statements presented to the Company by any of the Company's officers
or employees, committees of the Board or any other person or entity as to
matters the director, committee member or officer believes are within such other
person's professional or expert competence and who has been selected with
reasonable care by or on behalf of the Company.

          ------------
that an act be done or not be done a specified number of days prior to an event
or that an act be done during a period of a specified number of days prior to an
event, calendar days will be used unless otherwise specified, the day of the

          ----------

     provided, however, that the failure of a member of such committee to so
     --------  -------
     qualify will not invalidate any Stock Option granted by such committee.

          (l) "Stock Option" means the right to purchase one or more shares of
     Common Stock upon exercise of an option granted pursuant to Paragraph 5.

          (m) "Subsidiary" means any corporation, partnership, limited liability
     company, joint venture or other entity in which the Company owns or
     controls, directly or indirectly, not less than 50% of the total combined
     voting power or equity interests represented by all classes of stock or
     other equity interests issued by such corporation, partnership, limited
     liability company, joint venture or other entity.

     3.   Shares Available Under Plan.  The shares of Common Stock which may be
          ---------------------------
issued under the Plan will not exceed in the aggregate 12,554,713, subject to
adjustment as provided in this Paragraph 3. Such shares may be shares of
original issuance or treasury shares or a combination of the foregoing.

          (a) Any shares of Common Stock which are subject to Stock Options that
     are terminated unexercised, forfeited or surrendered or that expire for any
     reason will again be available for issuance under the Plan.

                                      -2-
<PAGE>

          (b) If, as of the close of business on the last day of each fiscal
     quarter of the Company following the effective date of the Plan, the sum of
     (i) the total number of shares of Common Stock previously issued upon the
     exercise of Stock Options and options granted by the Company or its
     predecessor prior to the effective date hereof, (ii) the total number of
     shares of Common Stock then subject to outstanding Stock Options and
     options granted by the Company or its predecessor prior to the effective
     date hereof, and (iii) the total number of shares of Common Stock then
     remaining available for future Stock Option grants under the Plan (such sum
     being the "Plan Shares") is less than 20% of the total number of shares of
     Common Stock then outstanding computed on a fully diluted basis (such total
     number being the "Outstanding Shares"), the number of shares of Common
     Stock available for issuance under the Plan will be increased (but not
     decreased) so that the number of Plan Shares will be equal to 20% of the
     number of Outstanding Shares. For purposes of the foregoing adjustment, all
     outstanding Stock Options and options granted under a Prior Option Plan or
     any other Company plans will be treated as fully exercised in computing the
     number of outstanding shares of Common Stock on a fully diluted basis,
     without regard to whether such options are then fully exercisable.

          (c) The shares available for issuance under the Plan also will be
     subject to adjustment as provided in Paragraph 7.

     4.   Individual Limitation on Stock Options.  The maximum aggregate number
          --------------------------------------
of shares of Common Stock with respect to which Stock Options may be granted to
any Participant during any single calendar year will not exceed 3,159,156.

     5.   Grants of Stock Options.  The Stock Option Committee or the Board may
          -----------------------
from time to time authorize grants to any Participant of Stock Options upon such
terms and conditions as the Stock Option Committee or the Board, as applicable,
may determine in accordance with the provisions set forth below.

          (a) Each grant will specify the number of shares of Common Stock to
     which it pertains.

          (b) Each grant will specify the Option Price, which will not be less
     than 100% of the Market Value per Share on the Date of Grant.

          (c) Successive grants may be made to the same Participant whether or
     not any Stock Options previously granted to such Participant remain
     unexercised.

          (d) Each grant will specify the required period or periods (if any) of
     continuous service by the Participant with the Company or any Subsidiary
     and/or any other conditions to be satisfied before the Stock Options or
     installments thereof will become exercisable, and any grant may provide, or
     may be amended to provide, for the earlier exercise of the Stock Options in
     the event of a change in control of the Company (as defined in the stock
     option agreement evidencing such grant or in any agreement referred to in
     such stock option agreement) or in the event of any other similar
     transaction or event.

                                      -3-
<PAGE>

          (e) Each Stock Option may be made subject to such transfer
     restrictions as the Stock Option Committee or the Board, as applicable, may
     determine.

          (f) Each grant will be evidenced by a stock option agreement executed
     on behalf of the Company by the Chief Executive Officer (or another officer
     designated by the Stock Option Committee or the Board, as applicable) and
     delivered to the Participant and containing such further terms and
     provisions, consistent with the Plan, as the Stock Option Committee or the
     Board, as applicable, may approve.

          (g) For purposes of any provision in a stock option agreement relating
     to the effect on a Stock Option of a Participant's ceasing to perform
     services for the Company or any Subsidiary, a termination of employment or
     other separation from service will occur when the Participant permanently
     ceases to perform services for the Company and all Subsidiaries or when the
     entity for which the Participant is performing services ceases to be a
     Subsidiary, unless the Participant immediately becomes employed by the
     Company or another Subsidiary.

     6.   Payment.  The Option Price will be payable, as required by the Stock
          -------
Option Committee or the Board in such Committee's or the Board's sole
discretion, as applicable, (i) in cash or by check acceptable to the Company,
(ii by the transfer to the Company of shares of Common Stock owned by the
Participant for at least six months (or, with the consent of the Stock Option
Committee or the Board, as applicable, for less than six months) having an
aggregate fair market value per share at the date of exercise equal to the
aggregate Option Price, (ii by authorizing the Company to withhold a number of
shares of Common Stock otherwise issuable to the Participant having an aggregate
fair market value per share on the date of exercise equal to the aggregate
Option Price, (iv in any other form of valid consideration or (v) by a
combination of such methods of payment; provided, however, that the payment
                                        --------  -------
methods described in clauses (ii) and (iii) will not be available at any time
that the Company is prohibited from purchasing or acquiring such shares of
Common Stock.  The Stock Option Committee or the Board, as applicable, may
permit deferred payment of the Option Price from the proceeds of sale through a
bank or broker of some or all of the shares to which such exercise relates.

     7.   Adjustments.  The Stock Option Committee or the Board may make or
          -----------
provide for such adjustments in the maximum number of shares specified in
Paragraphs 3 and 4, in the number of shares of Common Stock covered by
outstanding Stock Options granted hereunder, in the Option Price applicable to
any such Stock Options, and/or in the kind of shares covered thereby (including
shares of another issuer), as the Stock Option Committee or the Board, as
applicable, in its sole discretion, exercised in good faith, may determine is
equitably required to prevent dilution or enlargement of the rights of
Participants that otherwise would result from any stock dividend, stock split,
combination of shares, recapitalization or other change in the capital structure
of the Company, merger, consolidation, spin-off, reorganization, partial or
complete liquidation, issuance of rights or warrants to purchase securities or
any other corporate transaction or event having an effect similar to any of the
foregoing.  Moreover, in the event of any such transaction or event, the Stock
Option Committee or the Board, as applicable, in its sole discretion, may
provide in substitution for Common Stock to be delivered upon the exercise of
outstanding Stock Options such alternative consideration as it, in good faith,
may determine to be

                                      -4-
<PAGE>

equitable in the circumstances. In the event the Stock Option Committee
disagrees with the Board with respect to the foregoing adjustments, the Board's
determination will be final and conclusive. Any fractional shares resulting from
the foregoing adjustments will be eliminated.

     8.   Withholding of Taxes.  To the extent that the Company is required to
          --------------------
withhold federal, state, local or foreign taxes in connection with any benefit
realized by a Participant under the Plan, or is requested by a Participant to
withhold additional amounts with respect to such taxes, and the amounts
available to the Company for such withholding are insufficient, it will be a
condition to the realization of such benefit that the Participant make
arrangements satisfactory to the Company for payment of the balance of such
taxes required or requested to be withheld. In addition, if permitted by the
Stock Option Committee or the Board, a Participant may elect to have any
withholding obligation of the Company satisfied with shares of Common Stock that
would otherwise be transferred to the Participant on exercise of a Stock Option.

     9.   Administration of the Plan.  (a)  The Plan will be administered by the
          --------------------------
Stock Option Committee and the Board.  For purposes of any action taken by the
Stock Option Committee or the Board, whichever is applicable, a majority of the
members will constitute a quorum, and the action of the members present at any
meeting at which a quorum is present, or acts unanimously approved in writing,
will be the acts of the Stock Option Committee or the Board.

          (b) The Stock Option Committee and the Board have the full authority
and discretion to administer the Plan and to take any action that is necessary
or advisable in connection with the administration of the Plan, including
without limitation the authority and discretion to interpret and construe any
provision of the Plan or of any agreement, notification or document evidencing
the grant of a Stock Option and to make any determination of fact relating to
the foregoing.  The interpretation and construction by the Stock Option
Committee or the Board, as applicable, of any such provision and any
determination by the Stock Option Committee or the Board pursuant to any
provision of the Plan or of any such agreement, notification or document will be
final and conclusive; provided, that in the event the Stock Option Committee
                      --------
disagrees with the Board with respect to such interpretation, construction or
determination, the Board's determination will be final and conclusive.  No
member of the Stock Option Committee or the Board will be liable for any such
action or determination made in good faith.

          (c) Notwithstanding any provision of the Plan to the contrary, the
Stock Option Committee will have the exclusive authority and discretion to take
any action required or permitted to be taken under the provisions of Paragraph
7, Paragraph 9(a), Paragraph 9(b), Paragraph 10(a) and Paragraph 10(b) with
respect to Stock Options granted under the Plan that are intended to comply with
the requirements of Section 162(m) of the Code.

     10.  Amendments, Etc.  (a)  The Stock Option Committee or the Board, as
          ----------------
applicable, may, without the consent of the Participant, amend any agreement
evidencing a Stock Option granted under the Plan, or otherwise take action, to
accelerate the time or times at which the Stock Option may be exercised, to
extend the expiration date of the Stock Option, to waive any other condition or
restriction applicable to such Stock Option or to the exercise of such Stock
Option, to reduce the exercise price of such Stock Option, to amend the
definition of a change in control of the Company (if such a definition is
contained in such agreement) to expand the events

                                      -5-
<PAGE>

that would result in a change in control of the Company and to add a change in
control provision to such agreement (if such provision is not contained in such
agreement) and may amend any such agreement in any other respect with the
consent of the Participant.

          (b) The Plan may be amended from time to time by the Board or any duly
authorized committee thereof.  In the event any law, or any rule or regulation
issued or promulgated by the Internal Revenue Service, the Securities and
Exchange Commission, the National Association of Securities Dealers, Inc., any
stock exchange upon which the Common Stock is listed for trading, or any other
governmental or quasi-governmental agency having jurisdiction over the Company,
the Common Stock or the Plan, requires the Plan to be amended, or in the event
Rule 16b-3 is amended or supplemented (e.g., by addition of alternative rules)
                                       ----
or any of the rules under Section 16 of the Act are amended or supplemented, in
either event to permit the Company to remove or lessen any restrictions on or
with respect to Stock Options, the Stock Option Committee and the Board each
reserves the right to amend the Plan to the extent of any such requirement,
amendment or supplement, and all Stock Options then outstanding will be subject
to such amendment.

          (c) The Plan may be terminated at any time by action of the Board.
The termination of the Plan will not adversely affect the terms of any
outstanding Stock Option.

          (d) The Plan will not confer upon any Participant any right with
respect to continuance of employment or other service with the Company or any
Subsidiary, nor will it interfere in any way with any right the Company or any
Subsidiary would otherwise have to terminate a Participant's employment or other
service at any time.

          (e) The Plan will be governed by the laws of the State of Delaware
without regard to conflicts or choice of laws principles.

earned by Employee through the date of death or the date that Employee is
considered permanently and totally disabled, and (ii) grant to Employee all
Benefits accrued as of the date of death or the date that Employee is considered
to be permanently and totally disabled.  Also in such event, the Employer will
allow the Employee's spouse and dependent children to continue to participate in
the Employer's medical plan on the same basis as such continued participation is
provided to spouses and dependent children of other executive employees.  In the
event such continued participation is not possible for any reason, the Employer
will purchase health insurance coverage for the Employee's spouse and dependent
children that provides, to the extent practicable, reasonably comparable

completely satisfied, and Employer shall have no further obligations of any type
to Employee pursuant to this Agreement.

         5.2  Definition.  Employee shall be considered "permanently and totally
disabled" for purposes of this Section 5 in the event he is unable to perform
with reasonable continuity his material duties hereunder by reason of any
medically determinable physical or mental impairment which has lasted for a
continued period of not less than nine (9) months.

     6.  Confidentiality.  Employer agrees to provide access to, and the
Employee acknowledges that his employment under this Agreement may bring the
Employee into close contact with, many of the Employer's (which for purposes of
this Section 6 and Section 7 shall mean the Employer, its subsidiaries and
affiliated companies of each) confidential affairs, including information about
costs, profits, business opportunities, key personnel, operational methods,
plans for future development, and other business affairs, and other information
not readily available to the public.  The Employee further acknowledges that the
services agreed to under this Agreement are of a special and unique character
and that the Employer competes in nearly all of its business activities with
other organizations for which the Employee's services and expertise would be
valuable.  In recognition thereof, the Employee agrees and covenants:

     (a)  to keep confidential all information of the Employer which is not
publicly known or generally known to persons engaged in businesses similar or
related to those of Employer and not to disclose such matters to anyone outside
the Employer either while the Employee is employed with the Employer or
thereafter, except (i) with the Employer's express prior written authorization,
or (ii) pursuant to subpoena, court order or similar judicial process

                                       5

about which the Employee has given the Employer notice as soon as practicable
upon the Employee's receipt thereof;

     (b)  to deliver promptly to the Employer, upon termination of the
Employee's employment with the Employer (whether upon expiration of the Term or
prior thereto), or at any other time that the Employer may so request, all
memoranda, notes, records, reports, and other documents or other repositories of
information (all copies thereof) containing any information concerning
confidential information, whether prepared by the Employee, the Employer or
anyone else;

     (c)  not to make, publicly or privately, any disparaging remarks of any
nature whatsoever about the Employer or any of its employees, customers or
prospect (and the Employer agrees not to make, publicly or privately, any
disparaging remarks of any nature whatsoever about the Employee);

     (d) to coordinate with the Employer concerning comments, made publicly or
privately (other than to his immediate family), on his employment, except to the
extent reasonably required to obtain new employment, provided that all such
statements shall in any event be consistent with clause 6(c) hereof; and

     (e)  to keep confidential the terms of this Employment Agreement and to
disclose this Agreement's terms only to (i) a financial institution considering
a loan to Employee, (ii) tax or other governmental authorities, or (iii)
counsel, advisors or related parties of Employee who have been advised of the
confidentiality provisions of this Agreement.

For purposes of this Section 6 (other than clause (b) of the preceeding
sentence), all references to Employer shall include the Employer, any member of
the Wyly family or any affiliate of either.

     7.  Non-Interference.  During the Employee's tenure of employment with the
Employer and for one year thereafter, the Employee agrees to refrain from
interfering with the employment relationship between the Employer and its other
employees by soliciting, directly or indirectly, any such individual to
participate in, or be employed by, any business venture other than the Employer.
During the Employee's tenure of employment with the Employer and for a period of
one year thereafter, the Employee agrees to refrain from soliciting (for himself
or for any entity in which the Employee has an interest or by which the Employee
is employed) any business in any area or activity in which Employee or such
entity competes with Employer from any person who is a current client or
customer of the Employer at the termination date of the Employee's employment
with the Employer.

     8.  Return of Property on Termination.  In order to prevent the intentional
or unintentional disclosure of Employer's trade secrets by Employee, the Parties
agree that on termination of the Employee's employment, all of Employer's
property shall be promptly returned to Employer by Employee.  Without limiting
the generality of the term "Employer's property," Employer and Employee
stipulate that for the purposes of this Agreement, that term includes, but is
not limited to:  all credit cards, sales manuals, leasing manuals, brochures,
charts,

                                       6

graphs, price lists, customer account lists, prospective mailing lists, and any
other written or printed materials, recordings, photographs, films or slides
relating to the Employer's business, or any copies or reproductions of the
foregoing, and all equipment, hardware, and other property, given by the
Employer to the Employee or owned by Employer and in the possession or under the
direct or indirect control of Employee.

signed by the Party against whom enforcement of any waiver, change,
modification, extension or discharge is sought.

     12.  Severability.  If any provision of the Agreement is rendered or

incurred by Employee, in connection with the defense of, or as a result of any
action or proceeding (or any appeal from any action or proceeding) in which
Employee is made or is threatened to be made a party by reason of the fact that
Employee is or was an officer, employee or director of any corporation,
partnership or other organization which, directly or indirectly, controls or is
controlled by Employer, regardless of whether such action or proceeding is one
brought by or in the right of Employer.  Employer further represents and
warrants:  (i) that Employee shall be covered and insured up to the maximum
limits provided by all insurance which Employer maintains to indemnify its
directors and officers; and (ii) that Employer shall maintain such insurance, in
not less than its present limits, in effect throughout the term of this
Agreement.

remedies may be inadequate in the event of a breach of, or other failure to
perform, by the Employee any of the agreements set forth in Sections 6, 7, and 8
hereof, the Employer may, in addition to obtaining any other remedy or relief
available to it (including without limitation damages at law), enforce the

and all legal fees and expenses incurred by the Employee in connection with

Dallas, Texas                     $22,000,000                 April 23, 1999


     GREEN MOUNTAIN RESOURCES L.L.C., a Delaware limited liability company
having offices at 55 Green Mountain Drive, South Burlington, Vermont 05407
("Borrower"), for value received, promises to pay to the order of GREEN FUNDING
I, L.L.C., a Delaware limited liability company having offices at 300 Crescent
Court, Suite 1000, Dallas, Texas 75201, or its assigns ("Lender"), the principal
sum of $22,000,000.00 or such lesser amount advanced to Borrower from time to
time hereunder, together with all accrued and unpaid interest thereon, on or
before the earlier to occur of (i) April 23, 2001 or (ii) the tenth day
following the closing of a sale by the Borrower (or its successor) of securities
pursuant to its initial public offering (the "Maturity Date").  This Note will
evidence advances made from time to time prior to December 31, 1999 by Lender to
Borrower pursuant to the terms of the Funding Agreement, dated as of April 23,
1999 (the "Funding Agreement"), by and between Lender and Borrower.

     The unpaid principal balance of each advance hereunder will bear interest
at a per annum rate equal to 6%.  On each June 30 and December 31 all accrued
and unpaid interest will be capitalized and added to the then outstanding
principal.  In the event that the unpaid principal balance hereunder is not paid
in full on the Maturity Date, such unpaid principal balance will continue to
bear interest at a per annum rate equal to 6% as provided above, and principal,
interest and all other amounts owing hereunder will be due and payable on
demand.

     Notwithstanding any provision to the contrary herein contained, all amounts
owing under this Note will be due and payable in full on the Maturity Date.

     All or any portion of the principal amount owing under this Note may be
prepaid from time to time, in whole or in part, without premium or penalty.  Any
prepayment of this Note will be accompanied by all interest accrued on the
principal amount being prepaid.

     Principal, interest and all other amounts owing hereunder are payable to
Lender at the address designated by it from time to time.  All payments on this
Note will be made in lawful currency of the United States of America,
constituting same day funds, without setoff, counterclaim or other defense.

     All computations of interest hereunder will be made on the basis of a year
of 365 or 366 days, as the case may be.

     It is not the intention of any party hereto or any subsequent holder hereof
to make an agreement violative of the laws of any applicable jurisdiction
relating to usury.  In no event will Borrower be obligated to pay any amount in
excess of the maximum amount of interest permitted under applicable law.  If
from any circumstance the holder hereof ever receives anything of value deemed
excess interest under applicable law, an amount equal to such excess will be
applied to the reduction of the principal amount hereof, and any remainder will
be promptly refunded to the payor.




                                      -1-

     Borrower agrees to indemnify and hold harmless each holder of this Note
against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, claims, costs, expenses and disbursements of any kind
or nature whatsoever which may be imposed on, incurred by or asserted against
such holder or any of its partners, representatives, officers, directors,
employees or agents, in any way relating to or arising out of this Note or any
act, omission or transaction of Borrower or any of its partners,
representatives, officers, directors, employees or agents (including in
connection with or as a result, in whole or part, of the negligence of any such
person); provided, however, that a holder of this Note will not be so
indemnified and held harmless for any losses or damages which Borrower proves
were caused by such holder's willful misconduct or gross negligence, and such
holder will be liable to Borrower only to the extent of any direct (as opposed
to consequential) damages suffered by Borrower as a result of such holder's
willful misconduct or gross negligence.

     If this Note is placed in the hands of an attorney for collection after
default, or if all or any part of the indebtedness represented hereby is proved,
established or collected in any court or in any bankruptcy, receivership, debtor
relief, probate or other court proceedings, Borrower agrees to pay reasonable
attorneys' fees and collection costs incurred.

     Borrower hereby waives demand, presentment for payment, protest, notices of
any kind, including without limitation notice of protest and notice of intention
to accelerate the maturity of this Note, the bringing of any suit against any
party, and any notice of defense on account of any extensions, renewals, partial
payments or changes in any manner of or in this Note or in any of its terms,
provisions and covenants, or any releases or substitutions of any security, or
any delay, indulgence or other act of any holder hereof, whether before or after
maturity.

     If any provision of this Note is held to be illegal, invalid or
unenforceable under present or future laws during the term hereof, such improper
provision will be fully severable, this Note will be construed and enforced as
if such improper provision had never comprised a part hereof, and the remaining
provisions hereof will remain in full force and effect and will not be affected
by the improper provision or by its severance herefrom.  Furthermore, in lieu of
such improper provision, there will be added automatically as a part of this
Note a legal, valid and enforceable provision as similar in terms to the
improper provision as may be possible.

     Borrower may not assign or transfer its rights or obligations hereunder
without the prior written consent of the holder of this Note.  The holder of
this Note is hereby authorized by Borrower to record on a schedule annexed to
this Note (or on a supplemental schedule thereto) the amount of each advance to
Borrower hereunder and each payment made on this Note by Borrower, which
schedule will be conclusive and binding absent manifest error.  The failure to
make any such notation, however, will not affect the rights of the holder of
this Note or the obligations of Borrower hereunder or under any related
documents.

     This Note will be deemed to be a contract made and to be performed in
Dallas, Texas. This Note will be governed by and construed in accordance with
the laws of the State of Texas (without giving effect to conflict of law
principles) and the United States of America.  Without




                                      -2-
<PAGE>

excluding any other jurisdiction, Borrower agrees that the state and federal
courts of Texas located in Dallas, Texas will have jurisdiction over proceedings
in connection herewith.

     TO THE EXTENT PERMITTED BY APPLICABLE LAW, THE BORROWER HEREBY WAIVES ANY
RIGHT THAT IT MAY HAVE TO A TRIAL BY JURY OF ANY DISPUTE (WHETHER A CLAIM IN
TORT, CONTRACT, EQUITY OR OTHERWISE) ARISING UNDER OR RELATING TO THIS NOTE OR
ANY RELATED MATTERS, AND AGREES THAT ANY SUCH DISPUTE WILL BE TRIED BEFORE A
JUDGE SITTING WITHOUT A JURY.

     THIS NOTE AND THE FUNDING AGREEMENT REPRESENT THE FINAL AGREEMENT BETWEEN
THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR
SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.  THERE ARE NO UNWRITTEN ORAL
AGREEMENTS BETWEEN THE PARTIES.

     THIS NOTE HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1993, AS
AMENDED (THE "SECURITIES ACT"), OR THE SECURITIES LAWS OF ANY STATE AND MAY NOT
BE SOLD OR OTHERWISE TRANSFERRED UNLESS THIS NOTE IS REGISTERED UNDER THE
SECURITIES ACT AND ANY APPLICABLE STATE SECURITIES LAWS OR AN EXEMPTION FROM
SUCH REGISTRATION IS AVAILABLE.

                                    BORROWER:

                                PROMISSORY NOTE
                                ---------------

$_____,000                     January __, 1999



     FOR VALUE RECEIVED, the undersigned, _____________________ ("Maker"),
hereby promises to pay to the order of Green Mountain Energy Resources L.L.C., a
Delaware limited liability company (the "Payee" or the "Company"), at such
location as the Payee may from time to time designate in writing, in lawful
money of the United States of America, the principal sum of
________________________ and No/100 Dollars ($_____________), or so much thereof
as may be outstanding hereunder, together with interest on the outstanding
principal balance thereof at the rate of interest specified herein, on the
earlier of (a) the death or other termination of the Maker's employment or
performance of other services with the Payee or (b) December 31, 2003.

     The outstanding principal of this Note shall bear interest prior to
maturity at the rate of six percent (6%) per annum.   On each of the first four
anniversaries of the date of this Note, all outstanding accrued and unpaid
interest shall be capitalized and added to the then outstanding principal of
this Note and, after giving effect to each such capitalization of interest, the
outstanding principal of this Note (including all capitalized interest) shall
bear interest at the rate specified above.  All past due principal of and
interest on this Note shall bear interest at the Maximum Rate (hereinafter
defined).

     This Note is delivered to the Payee pursuant to the Subscription Agreement
between the Maker and the Payee of even date herewith as partial payment for
Units of the Company purchased by the Maker pursuant to the Company's Employee
Unit Purchase Plan (the "Plan").  Payment of this Note is secured by said Units
and any other securities issued by  the Payee owned or hereafter acquired by the
Maker (the "Collateral").  The Maker hereby grants to the Payee a first priority
security interest in the Collateral which is held as security on behalf of the
Payee by Evan A. Wyly, as Escrow Agent, pursuant to an Escrow Agreement entered
into in connection with the Plan.  The Maker represents and warrants that the
Maker has delivered (or caused to be delivered) all Collateral owned on the date
hereof to the Escrow Agent on or before the Maker's execution of this Note and
agrees so to deliver (or cause to be delivered) any Collateral hereafter
acquired.  The Maker acknowledges and agrees that the Escrow Agent is authorized
to act on behalf of the Payee pursuant to the terms of the Escrow Agreement.
If, while the Collateral is in the possession of the Escrow Agent, the Company
makes any distribution to the holders of its equity securities, other than a
distribution of cash, the property so distributed in respect of the Collateral
will be delivered to the Escrow Agent and held pursuant to the terms of this
Note and the Escrow Agreement.  The Payee shall have the right to cause its
rights in the Collateral to be noted in the Unit ownership records of the
Company, provided that such notation shall be removed upon the Maker's
satisfaction of all obligations secured by the Collateral.  Except to the extent
of the Collateral, this Note is without recourse to, and does not constitute a
general liability of, the Maker.  All payments on this Note shall be made
without offset, counterclaim or other defense.

     In the event the Maker sells or otherwise disposes of all or a portion of
the Collateral (including any disposition for no consideration), as permitted
under the terms of the Plan, the Maker shall pay to the Payee a portion of the
then outstanding principal and accrued interest under this Note.  The amount of
such required payment shall represent the same proportion of the outstanding
principal and interest under this Note as the Collateral sold or disposed of
represents of all Units acquired under the Plan and owned by the Maker (subject
to the security interest of the Payee) immediately prior to such sale or other
disposition.  The amount of such required repayment will be made to the Payee in
cash upon the closing of the sale or disposition of the Collateral.

     In addition to the repayment obligation described in the preceding
paragraph, in the event the Maker sells or otherwise disposes of all or a
portion of the Collateral, the Maker will be obligated to repay
<PAGE>

an additional amount of principal and interest under this Note equal to 50% of
the Maker's gain, but in no event more than the outstanding principal balance
and accrued interest under this Note. For purposes of this paragraph, the Maker
will be deemed to have realized gain (i) upon the sale or other disposition of
the Collateral, to the extent the Maker receives cash or other consideration
with a fair market value in excess of $10.00 per Unit (net of (A) related
transaction costs and (B) income taxes on such excess (determined without regard
to this clause and computed on the basis of an assumed rate of 25%)) and (ii)
upon the disposition of Collateral without consideration, to the extent the fair
market value of the Collateral transferred exceeds $10.00 per Unit. The fair
market value of the Collateral will be determined from time to time by the
Committee, established under the terms of the Plan, at the sole discretion of
the Committee.

     Any determination of fair market value by the Committee shall be final and
binding unless and until updated or changed by the Committee.  Such amount shall
be due and payable to the Payee in cash upon the closing of the sale or other
disposition of the Collateral.   For purposes hereof, in the event the Maker
sells or otherwise disposes of Units held as Collateral, the Units first sold or
otherwise disposed of by the Maker will be deemed to be Units purchased under
the Plan.

     All times of payment of principal, interest and any other amounts due under
this Note shall be of the strict essence.

     Interest on the indebtedness evidenced by this Note shall be computed on
the basis of a year of 360 days and the actual number of days elapsed (including
the first day but excluding the last day) unless such calculation would result
in a usurious rate, in which case interest shall be calculated on the basis of a
year of 365 or 366 days, as the case may be.  The Maker shall have the right to
prepay, at any time and from time to time without premium or penalty, the entire
unpaid principal balance of this Note or any portion thereof.

     All payments made under this Note shall be applied, regardless of how they
are designated by the Maker, as follows: first, to the payment of any costs
incurred by the Payee in collecting or enforcing this Note; second, to the
payment of interest due under this Note; and third, to the outstanding principal
balance of this Note.

     As used in this Note, "Maximum Rate" means the lesser of twelve percent
(12%) or the maximum rate of nonusurious interest permitted from day to day by
applicable law.

     Notwithstanding anything to the contrary contained herein, no provisions of
this Note shall require the payment or permit the collection of interest in
excess of the Maximum Rate.  If any excess interest in such respect is herein
provided for, or shall be adjudicated to be so provided, in this Note, the
provisions of this paragraph shall govern and prevail, and neither of the Maker
nor the sureties, guarantors, successors or assigns of Maker shall be obligated
to pay the excess amount of such interest, or any other excess sum paid for the
use, forbearance or detention of sums loaned pursuant hereto.  If for any reason
interest in excess of the Maximum Rate shall be deemed charged, required or
permitted by any court of competent jurisdiction, any such excess shall be
applied as a payment and reduction of the principal of indebtedness evidenced by
this Note; and, if the principal amount hereof has been paid in full, any
remaining excess shall forthwith be paid to the Maker.  In determining whether
or not the interest paid or payable exceeds the Maximum Rate, the Maker and the
Payee shall, to the extent permitted by applicable law, (i) characterize any
nonprincipal payment as an expense, fee, or premium rather than as interest,
(ii) exclude voluntary prepayments and the effects thereof and (iii) amortize,
prorate, allocate, and spread in equal or unequal parts the total amount of
interest throughout the entire contemplated term of the indebtedness evidenced
by this Note so that the interest for the entire term does not exceed the
Maximum Rate.

     The Maker shall be in default hereunder upon the happening of any of the
following events or conditions (each such event or condition hereinafter
referred to as an "Event of Default"):




                                       2
<PAGE>

          (a) Any representation, warranty, or statement made or deemed made by
     Maker to the Payee shall be false, misleading, or erroneous in any material
     respect when made or deemed to have been made.

          (b) Maker shall default in the timely payment or performance of any
     obligation, covenant or agreement made or owed by Maker to the Payee.

          (c) Maker shall commence a voluntary proceeding seeking liquidation,
     reorganization, or other relief with respect to itself or its debts under
     any bankruptcy, insolvency, or other similar law now or hereafter in
     effect, or seeking the appointment of a trustee, receiver, liquidator,
     custodian, or other similar official for it or a substantial part of its
     property or shall consent to any such relief or to the appointment of or
     taking possession by any such official in an involuntary case or other
     proceeding commenced against it or shall make a general assignment for the
     benefit of creditors or shall generally fail to pay its debts as they
     become due.

          (d) Any involuntary proceeding shall be commenced against Maker
     seeking liquidation, reorganization, or other relief with respect to Maker
     or Maker's debts under any bankruptcy, insolvency, or other similar law now
     or hereafter in effect, or seeking the appointment of a trustee, receiver,
     liquidator, custodian, or other similar official for Maker or a substantial
     part of Maker's property, and such involuntary proceeding shall remain
     undismissed and unstayed for a period of thirty (30) days.

          (e) Maker shall fail to discharge within a period of thirty (30) days
     after the commencement thereof any attachment, sequestration, or similar
     proceeding or proceedings involving an aggregate amount in excess of
     Twenty-Five Thousand Dollars ($25,000) against any of Maker's assets or
     properties.

          (f) Maker shall fail to satisfy and discharge promptly any judgment or
     judgments against Maker (not stayed pending appeal) for the payment of
     money in an aggregate amount in excess of Twenty-Five Thousand Dollars
     ($25,000).

          (g) Maker shall default in the payment of any of its indebtedness
     beyond any applicable grace period, or shall default in a material way in
     its performance of any agreement binding upon it or its property, or a
     default or event of default shall occur under the terms of any agreement,
     document or instrument securing or otherwise relating to this Note.

          (h) This Note shall cease to be in full force and effect or shall be
     declared null and void or the validity or enforceability hereof shall be
     contested or challenged by Maker, or Maker shall deny that it has any
     further liability or obligation under this Note.

          (i) Maker or any guarantor, surety, or other person or entity ever
     liable for the payment of this Note shall have died or become incompetent.
     Any determination that any such person is incompetent shall be based upon
     either (i) the written opinion of a physician that such person is
     incompetent to handle his or her own financial affairs or (ii) a court
     order adjudicating such person to be incompetent.

     Upon the occurrence of any Event of Default, the holder hereof may, at its
option, terminate any commitment on the part of the Payee or its affiliates to
make loans to Maker and declare the entire unpaid principal of and accrued
interest on this Note immediately due and payable without notice (including
notice of acceleration or of intent to accelerate), demand, protest, or
presentment, all of which are hereby waived, and upon such declaration, the same
shall become and shall be immediately due and payable, and the holder hereof
shall have the right immediately and without notice, except as otherwise
provided below, (a) to foreclose or otherwise enforce and realize upon all liens
or security interests securing payment hereof, or any part hereof, and in
connection therewith, sell or otherwise dispose of and deliver the Collateral,
or any


                                       3
<PAGE>

part thereof, in one or more parcels at public or private sale or sales at the
holder's offices or elsewhere, at such prices and on such terms as the holder
may deem acceptable, (b) to offset against this Note any sum or sums owed by the
holder hereof to Maker, (c) exercise any and all rights of a secured party as
provided for in the Uniform Commercial Code, (d) proceed to have all Collateral
registered in the holder's name or in the name of a nominee, and (e) enforce any
one or more remedies hereunder, successively or concurrently. In connection with
any sale or disposition of the Collateral hereunder, the holder need not give
more than ten (10) calendar days notice of the time and place of any public sale
or of the time after which a private sale may take place, which notice Maker
hereby acknowledges to be adequate and reasonable. Failure of the holder hereof
to exercise its rights hereunder shall not constitute a waiver of the right to
exercise the same upon the occurrence of a subsequent Event of Default.

     If the holder hereof expends any effort or money in any attempt to enforce
payment of all or any part or installment of any sum due the holder hereunder,
or if this Note is placed in the hands of an attorney for collection, or if it
is collected through any legal proceedings, Maker agrees to pay all collection
costs and fees incurred by the holder, including reasonable attorneys' fees.

     This Note shall be governed by and construed in accordance with the laws of
the State of _____________ and the applicable laws of the United States of
America.  This Note is performable in ________________________________.  Any
action or proceeding under or in connection with this Note against Maker or any
surety, guarantor, endorser or other party liable for payments owed hereunder
may be brought in any state or federal court in
________________________________.  Maker and each such other party hereby
irrevocably (i) submits to the nonexclusive jurisdiction of such courts and (ii)
waives any objection it may now or hereafter have as to the venue of any such
action or proceeding brought in such court or that such court is an inconvenient
forum.  Nothing herein shall affect the right of the Payee to bring any action
or proceeding against Maker or any other party liable hereunder or with respect
to any collateral in any state or federal court in any other jurisdiction.  Any
action or proceeding by Maker or any other party liable hereunder against the
Payee shall be brought only in a court located in
________________________________.

     Maker and each surety, guarantor, endorser, and other party ever liable for
payment of any sums of money payable on this Note jointly and severally waive
notice, presentment, demand for payment, protest, notice of protest and non-
payment or dishonor, notice of acceleration, notice of intent to accelerate,
notice of intent to demand, diligence in collecting, grace, and all other
formalities of any kind, and consent to all extensions without notice for any
period or periods of time and partial payments, before or after maturity, and
any impairment of any collateral securing this Note, all without prejudice to

3.  Charges

     A.  Minimum Monthly Retainer

$30,000 during the term of this agreement ("Minimum Monthly Retainer"). The
Minimum Monthly Retainer will be credited against charges incurred on your
behalf for all agency services/purchases except: a) media time/space, and b)
direct response postage charges.

B. Quarterly Budgets and Monthly Advance Payments
<PAGE>

Prior the the commencement of each calendar quarter, we shall agree upon a
budget for monthly expenditures during such quarter. You agree to make monthly
advance payments, due by the first day of each month, in the amount of
anticipated prepaid expenses, including media time/space and direct response
postage, for such month as reflected in the quarterly budget less the amount of
the Minimum Monthly Retainer described above ("Monthly Advance Payments").
Within 15 days of the end of each month, we will provide you with an invoice for
the actual charges by job incurred during such month in excess of the Monthly
Advance Payment and such amount shall be due and payable by you within 30 days
of your receipt of such invoice. During any quarter, you may amend the budget as
you deem appropriate and we will implement the budget as amended. We agree not
to exceed approved quarterly budgets by more than ten percent in any quarter
without your prior written approval. The budget for the period January 1, 1998
though March 31, 1998 is set forth on Exhibit A attached hereto.

     Quarterly Budgets shall include the following line items if applicable:

     1.  Advertising Space and Time

You agree to pay us at current published rates (or at lower rates when
available) plus an amount which (together with commission, if any, allowed by
media) will yield us ***% of our total charge to you before cash discounts, if
any.

     2.  Direct Response Marketing

To the extent not paid in Monthly Advance Payments, postage relative to direct
response marketing must be paid a minimum of 2 days prior to submission to post
office and will be billed at "Net Cost." As used in this agreement, Net Cost
shall mean our actual cost, net of any realized discounts.

You agree to pay us the Net Cost of all Freight/Shipping materials and services
purchased on your behalf, plus an amount that will yield us ***% of our total
charges to you.

     3.  Design Materials and Services

You agree to pay us the Net Cost of all design materials and services purchased
from Yamamoto Moss, Inc., on your behalf, plus an amount that will yield us ***%
of our total charge to you.

     4.  General Agency Services

Except as otherwise noted herein, you agree to pay us the net cost of all
materials and services purchased on your behalf, plus an amount that will yield
us ***% of our total charge to you, except that for all "merchandise" purchased
on your behalf our commission shall be ***% of our total charge to you.
"MERCHANDISE" SHALL MEAN TANGIBLE/DIMENSIONAL ARTICLES, NOT PRINTED, TO INCLUDE:
(A) ADVERTISING SPECIALTIES, SOME BEARING LOGO IMPRINTS; (B) DIMENSIONAL ITEMS
USED IN CONJUNCTION WITH TRADE SHOW EXHIBITS, GOODWILL GESTURES OR PREMIUM

***Confidential treatment has been requested for the redacted portions. The
confidential redacted portions have been filed separately with the Securities
and Exchange Commission.
<PAGE>

includes all cost of client services which are clearly defined below the line on
our General Agency Fee Schedule, attached hereto as Exhibit B. We Agree to
renegotiate merchandise compensation on a quarterly basis, if requested by you.

5.  Taxes

You agree to pay all sales, use and payroll taxes that we are required by law
to collect or pay in connection with your account for any purchases made or
talent charges incurred on your behalf.

     6.  Agency Time Charges

You agree to pay us for services rendered on your behalf at our then current
hourly rates. When relative to a specific project, the anticipated charge for
agency services will be incorporated into the project estimate in quarterly
budgets. Consultation and strategic planning of a general nature will be
undertaken at your request and will be charged as incurred at our then current
hourly rates (General Agency Fee Schedule attached hereto as Exhibit B).

     7.  Miscellaneous

You agree to pay us at our then current rates for color outputs and color copies
related to the production of advertising/marketing materials. You also agree to
pay us for travel and/or incidental costs which you request or which are
connected with the production of your marketing materials.

     8.  Advertising Placed Outside the U.S.

Since conditions vary from company to company and from country to country, it is
not feasible to establish a policy regarding compensation to us for advertising
you adapt, translate or use in part or whole outside the U.S. If such use
occurs, it is agreed that we will jointly review to determine the amount of
compensation to be paid to us for such use.

4.  Terms of Payment

     A.  Fundamental Principles

Our relationship is based on three fundamental principles:

(1) We will finance our own agency services, but not the advertising of our
clients; and

(2) We are solely liable for payment of media invoices only after we have been
paid for those invoices by you. Prior to payment to us, you are and will remain
solely liable; and

(3) All services obtained or provided by us or our subcontractors to you and
Work Product produced thereby shall, upon payment by you, become your exclusive
property to the extent of property rights otained by us on your behalf which
shall be maintained in confidence as required under this
<PAGE>

agreement.

     B.  Agreement to Pay

Payment of each month's statement is due thirty (30) days following receipt of
the invoice by you and will be past due after that date. A monthly service
charge of 1-1/2% will be added to the outstanding balance of accounts over
thirty (30) days past due. You are liable for any collection charges or attorney
fees incurred by us in collecting your account, if delinquent.

     C.  Collateral, Print, and Broadcast Production

We will prepare estimates for collateral materials, and print and broadcast ad
production for your approval in quarterly budgets. Based on the estimate
approved by you, which may vary by plus or minus 10%, we will invoice you for
the estimated cost at the inception of a project. You agree to pay these
invoices in accordance with the terms stated above. Estimated charges will be
reconciled to actual costs upon project completion.

     D.  Advertising Space and Time

We will invoice you for advertising space and time in the month prior to the
flight or circulation, so that your payment to us will coincide, as closely as
possible, with our payment responsibility to media.

     E.  Right to Change Payment Terms

We reserve the right in case of delinquency in your payments to us, or such
impairment of your credit as in our reasonable opinion might endanger future
payments to us, to change the requirements as to terms of payment under this
agreement.

     F.  Cash Discounts

Cash discounts from media or other suppliers, to which we may be entitled by
your prompt payment to us, will be passed on to you.


5.  General Provisions

     A.  Mutually Exclusive Arrangement

During the term of this agreement and for a period of six months following its
termination, we agree to refrain from acting as advertising agency for any
environmentally branded products directly competitive with yours, without your
written consent. During the term of this agreement, you agree not to engage the
services of any other advertising agency without first obtaining our written
consent.

Notwithstanding the foregoing, we acknowledge and agree that you have previously
engaged other parties as marketing consultants, including but not limited to
Copernicus with respect to marketing research and strategy and The Weber Group
with respect to public relations and events, and
<PAGE>

that you may in the future engage other consultants. We agree to cooperate with
your other consultants.

are acting as your authorized agent in purchasing such goods and services for
you and performing such services required by us under this agreement.

materials entrusted to us as your property, and will use reasonable efforts to
secure their return from third parties.

     D.  Cancellation of Plans

stop any and all plans, schedules or work in process which you previously
approved; and in such event we will take proper steps to carry out your
instructions; but you agree to assume all liability for all commitments, and to
reimburse us for any losses we may sustain or expenses we may incur derived
therefrom, and to pay us any service charges relating thereto.

     E.  Failure of Suppliers to Perform

To the best of our ability, we will endeavor to guard against loss to you
through the failure of media or suppliers to properly execute their commitments,
but we are not responsible for any failure on their part.

     F.  Releases

We will obtain all necessary releases, licenses, permits or other authorizations
to use photographs, trademarks, copyrighted materials, artwork or any other
property or rights belonging to third parties obtained by us for use in
performing services for you and we agree to discuss with you the scope of such
rights acquired on your behalf. You will obtain the same for any materials
obtained by you that are used by us in performing our services, and you will be
responsible for any claims with respect to such use.

publicity, and other marketing communications for you, with a view to avoiding
any claims, challenges, proceedings or suits against you or ourselves.

concerning your products and services that you furnish to us.

against you, based upon material prepared by us, involving any claim for libel,
slander, piracy, plagiarism, invasion of privacy,
<PAGE>

infringement of copyright, infringement of trade dress, unfair competition or
deceptive advertising, except (1) where any such claim or action may arise out
of information or material supplied by you to us and incorporated in material
prepared by us, or (2) for any such claim or action arising under regulations
specifically applicable to energy retailers or based on disclosures concerning
the environmental attributes of your products and services.

You will indemnify and hold us harmless with respect to any claims or actions
instituted by a third party which results from the use by us of material
furnished by you or where material created by us is substantially changed by
you. Information or data obtained by us from you to substantiate claims made in
advertising shall be deemed to be "material furnished to us by you."

     H.  Confidentiality

proprietary and will maintain it in confidence. The Confidential Information

access, to read and countersign a facsimile of this provision.

disclosing party, the Confidential Information and any copies made thereof shall
be immediately returned to the disclosing party, notwithstanding the existence
of any claim or dispute between the parties, or the availability of any legal or
equitable basis, including any lien, upon which either party or its successors
or assigns might assert a claim to continued possession thereof.

The parties and their employees and agents agree that disclosure of any
<PAGE>

Confidential Information except as authorized in this provision, or any
violation of this provision, will cause the disclosing party immediate and
irreparable harm remediable by preliminary and permanent injunctive relief, in

2.   Type of Service:
     Subject to the terms, conditions and restrictions contained herein,
Supplier will provide Full Requirements Service to Green Mountain.

3.   Term:
     A.  This Agreement shall become effective on the date set forth below;
provided, however, neither Party shall have any obligations relative to
deliveries of any Wholesale Products or Undifferentiated System Power  until the
date that Green Mountain is permitted under the regulatory laws of the
Commonwealth of Pennsylvania and the applicable EDC to commence deliveries of
Retail Products to Designated Green Mountain Customers (anticipated to be
January 1, 1999). Unless terminated earlier in accordance with Paragraph 23
hereof,  this Agreement shall continue until the expiration of the Measurement
Period for the last Customer Group.

     B.  Either Party may give the other at least three months advance written
notice of such Party's decision to cease assigning or accepting allocation of
Load Profiled Retail Customers to Supplier.  The earliest that such notice may
be effective is March 31, 1999.  Upon the effective date of such notice, Green
Mountain shall cease allocating customers in the Pennsylvania EDC service
territories to Supplier.  However; (a) this Agreement and all rights and
obligations hereunder shall remain in full force and effect, following the
effective date of such notice, with respect to each Customer Group allocated to
Supplier prior to such effective date until the expiration of the Measurement
Period for each such Customer Group; and (b) Green Mountain shall be able to
allocate additional Load Profiled Retail Customers to existing Customer Groups
through April 2000, if the total CEER of the then existing Customer Groups is
below 50% of the generation resource levels as indicated in Paragraph 5
(Quantity) as it may be reduced as provided in Paragraph 5(D) or (E) until such
CEER of the Customer Groups is 50% or more of the level stated in Paragraph 5 as
it may be reduced as provided in Paragraph 5(D) or (E).

     C.  If there are PJM, ECAR, PaPUC or FERC Rule, policy or other changes;
establishment of new ISO(s) or dissolution of existing ISO(s), other than
reallocation of charges covered by Base Charge Adder (b), that are proposed by
the applicable regulatory body after the date of this Agreement to be effective
before the expiration of this Agreement that have a material adverse effect on
either or both Parties, then upon written notice from the adversely effected
Party, the Parties shall attempt to negotiate changes to the Agreement
acceptable to both Parties.  In the event that mutually acceptable changes are
not negotiated and executed within 10 days of such notice, either Party may
cease the allocation of additional Load Profiled Retail Customers to Supplier on
5 days written notice; provided, however, that regardless of the dates of such

                                                                    Confidential


notices Green Mountain may allocate Load Profiled Retail Customers to Supplier
through October 31, 1998 unless Supplier documents that the adverse effect
resulted or will result in a cost increase of 10% or more.

4.   [Intentionally Omitted]

5.   Quantity:

     A.  Green Mountain shall purchase energy from Supplier that is necessary to
provide Full Requirements Service to Designated Green Mountain Customers as
follows:  at least ***% of the total number of Load Profiled Retail Customers of
Green Mountain in the Pennsylvania EDC service territories that agree to
purchase each of the Retail Products set forth in Attachment A. Load Profiled
Retail Customers shall be allocated for each EDC on a Random Basis to Supplier,
with the exception that Green Mountain shall use reasonable efforts to ensure
that Supplier employees and/or their families requesting retail service from
Green Mountain shall become Designated Green Mountain Customers.

     B.  In the event that one or more EDC's do not allow Green Mountain to
utilize multiple suppliers of Wholesale Products, Green Mountain shall have the
right to allocate Load Profiled Retail Customers within any such EDC to a single
supplier of a Wholesale Product, which supplier may or may not be Supplier. In
such a situation, Green Mountain will endeavor to allocate Load Profiled Retail
Customers in other EDC's to its Wholesale Product suppliers in a manner which
adjusts equitably for Green Mountain's inability to allocate Load Profiled
Retail Customers in such EDC(s) to more than one Wholesale Product supplier.
Prior to such a reallocation of Load Profiled Retail Customers, Green Mountain
shall pursue on a good faith basis the establishment of a single coordination
agent to consolidate interface requirements with any such EDC to allow for
provision of Wholesale Products by multiple suppliers.

     C.  For each Wholesale Product, Supplier's obligation to accept additional
Load Profiled Retail Customers shall cease at such time as the CEER  would
exceed the following generation resource levels, by region:

                           PJM Region       ECAR Region
                           ----------       ------------

Clean Power Resources         ***               ***

Renewable Resources           ***               ***

New Renewable Resources       ***               ***

***Confidential treatment has been requested for the redacted portions. The
confidential redacted portions have been filed separately with the Securities
and Exchange Commission.

                                                                    Confidential


     D.  Supplier has an option to reduce any or all the above generation
resource levels by up to 10% by giving Green Mountain 30 days advance written
notice but not below the level required by Designated Green Mountain Customers
previously allocated to Supplier.

     E.  Supplier's obligation to accept additional Designated Green Mountain
Customers is Wholesale Product specific, and remains in force for any Wholesale
Product generation resource types that have not exceeded their respective CEER.
In the event that regulatory or legal action or force majeure prevents or
interrupts the introduction of retail access in one or more of the EDC's,  the
above generation resource levels shall be reduced by the ratio of the amount of
retail electric energy requirements of the affected EDC(s) measured by the
system sales (MWh) of such EDC for 1997 to the total retail electric energy
requirements of all EDC's in the Commonwealth of Pennsylvania measured by the
total of such EDC's system  sales (MWh) for 1997 for the period during which
such retail access is prevented or interrupted.

     F.  Supplier acknowledges that Green Mountain is blending various full
requirements purchases of Wholesale Products from multiple suppliers on a
monthly basis to create and serve its Retail Products. Green Mountain intends to
blend New Renewable Resources purchased from Supplier with other Wholesale
Products purchased from other suppliers to create Retail Products for Green
Mountain customers in Pennsylvania served by said other suppliers.  The Retail
Products are differentiated by the ratio of energy from Clean Power Resources,
Renewable Resources, and New Renewable Resources which they contain.  Green
Mountain will track the respective loads and content requirements of each of its
Wholesale Product suppliers, including Supplier, and will determine the quantity
of New Renewable Resources required from Supplier for blending with the
Wholesale Products supplied by other  Wholesale Product suppliers to meet the
energy content required for Green Mountain's Retail Load Profiled Customers.  To
the extent that Supplier supplies Green Mountain with quantities of New
Renewable Resources in any calendar year in excess of the quantities required to
meet the New Renewable Resources content for the Designated Green Mountain
Customers due to Green Mountain's blending requirements, the quantities of Clean
Resources and Renewable Resources to be supplied hereunder by Supplier for such
calendar year shall be reduced by an amount corresponding with the excess
quantity of New Renewable Resources delivered.

     G.  Green Mountain will issue a Special Content Declaration to Supplier on
a monthly basis specifying the mix required from Supplier for its Wholesale
Product. The Special Content Declaration will be calculated by Green

                                                                    Confidential


Mountain as described in Attachment B attached hereto and made a part hereof,
for both PJM and ECAR and provided to Supplier as soon as possible but no later
than 5 days before the beginning of each month.

     H.  Supplier shall schedule and deliver energy from Renewable Resources,
Clean Power Resources, New Renewable Resources, in the ratio specified in the
Special Content Declarations and/or Undifferentiated System Power to the Energy
Delivery Points at times and amounts sufficient to provide Full Requirements
Service.

     I.  Green Mountain will be responsible for obtaining measured load and
energy consumption information and shall provide, or cause to be provided, such
information to Supplier as and when received as well as Reconciliation with the
EDC(s) and PJM to the extent not provided by the EDC(s) or PJM. Any costs
associated with reading a particular Designated Green Mountain Customer's
metering equipment or meter reading will be borne by Green Mountain.

     J.  To the extent that there are no adverse economic or operational effects
on Supplier, Supplier will use Supplying Resources it has secured in PJM to
deliver to Energy Delivery Points in PJM and use Supplying Resources it has
secured in ECAR to deliver to Energy Delivery Points in ECAR.

6.   New Renewable Resources:

     Supplier agrees to secure energy from  New Renewable Resources, which will
include landfill gas, for delivery under this Agreement.  Such New Renewable
Resources shall have a planned availability date of no later than October 1,
1999.  Supplier shall begin procurement upon execution of this Agreement and
shall thereafter diligently pursue completion of construction and/or necessary
purchase contracts.

     Green Mountain is pursuing the development of a photovoltaic ("PV")
facility to be sited in Pennsylvania with a target commercial operation date of
November 1, 1999. If requested by Green Mountain, Supplier agrees to accept
assignment of the electric energy output of this facility during the term of
this Agreement, and will be compensated through an administrative fee and full
cost reimbursement. All costs associated with such PV facility, including but
not limited to energy, transmission, distribution and ancillary service charges,
shall be documented by Supplier and be paid by Green Mountain. Supplier will
have no responsibility for the output, other than scheduling, and Green Mountain
will indemnify Supplier for all expenses or liabilities it may incur in
connection with such PV facility, including, but not limited to energy imbalance
or unauthorized use charges. The PV generation shall either displace New

Renewable Resource or Renewable Resources as determined by Supplier.

     Green Mountain anticipates the acquisition and retail sale of other
Renewable Resources and New Renewable Resources which may further alter content
requirements of its Wholesale Products. The Parties agree to attempt to
negotiate an arrangement to accommodate these additional resources.

7.   Liquidated Damages:
     (a)  If, for reasons other than force majeure or Green Mountain's failure
          to perform Supplier fails to deliver the Full Requirements Service
          and, Green Mountain acting in a commercially reasonable manner incurs
          incremental costs and expenses to provide such Full Requirements
          Service over and above those it would have incurred had Supplier
          fulfilled its obligation, then such costs and expenses shall be
          charged to Supplier, and Green Mountain shall have the right to deduct
          such costs and expenses from any amounts payable to Suppliers.

     (b)  If, for reasons other than force majeure or Green Mountain's failure
          to perform, Supplier fails to satisfy its delivery obligations with
          respect to Wholesale Products, Green Mountain acting in a commercially
          reasonable manner shall be free to purchase substitute Wholesale
          Products from third parties to cover Supplier's failure to deliver
          same and Supplier shall reimburse Green Mountain for any incremental
          costs and expenses which it incurs to purchase said Wholesale Products
          less the revenue received by Green Mountain from the sale of such
          Wholesale products if Supplier has not failed to supply Full
          Requirements Service.

     (c)  Incremental costs and expenses reimbursable hereunder are  energy,
          transmission services, scheduling functions, ancillary services
          reasonably incurred in connection with securing such replacement
          supplies in excess of what would have been paid to Supplier.  Green
          Mountain will use reasonable efforts to mitigate the damages payable
          or reimbursable by Supplier hereunder.

     (d)  If, for reasons other than force majeure or Supplier's failure to
          perform, Green Mountain fails to purchase Full Requirements Service,
          Green Mountain shall pay Seller, on the date payment would otherwise
          be due, an amount for each MWh of such deficiency equal to the
          positive difference, if any, obtained by

                                      -8-

                                                                    Confidential


          subtracting the per unit Sales Price from the prices that would have
          been paid by Green Mountain.

          "Sales Price" means the price at which Supplier, acting in a
          commercially reasonable manner, resells, or if not resold would have
          been able to resell, the Wholesale Products not received by Green
          Mountain, reduced by additional transmission charges, if any
          (including, without limitation, charges for any applicable ancillary
          services), incurred by Supplier to effect such resale.

8.   Product Verification:

     A.  Resources that will be relied upon by Supplier to meet the Wholesale
Product requirements shall be either owned by Supplier, subject to contracts
with any party having dispatch rights to the energy, or subject to other
contractual entitlements sufficient to meet the verification requirements.

     B.  Supplier will use reasonable efforts to attempt to deliver Wholesale
Products as specified in the Special Content Declarations in the calendar year
but each Wholesale Product may be delivered, at Supplier's option, either to
Green Mountain for delivery to Designated Green Mountain Customers or other
customers as follows:

         Supplier will have satisfied all of its obligations with respect to
delivery of each Wholesale Product in PJM if Supplier:

    (a)   Delivers Wholesale Products to Green Mountain in PJM in the ratio
          specified in the December Special Content Declaration for PJM and in
          an amount equal to 95-105% of the Designated Green Mountain Customer
          Load each calendar year or with 4 months after the end of the calendar
          year;

     (b)  Delivers Wholesale Products to retail or wholesale customers in PJM
          other than Green Mountain or Designated Green Mountain Customers in
          the ratio specified in the December Special Content Declaration and in
          an amount equal to 95-105% of the Designated Green Mountain Customer
          Load in PJM each calendar year where Supplier does not transfer to
          such other customer(s) the rights to claim the environmental
          attributes that differentiate such Wholesale Products from
          Undifferentiated System Power; or

     (c)  Any combination of (a) or (b).

                                                                    Confidential


     Supplier will have satisfied all of its obligations with respect to
delivery of each Wholesale Product in Pennsylvania EDC(s) in ECAR, if Supplier:

     (d)  Delivers Wholesale Products to Green Mountain in Pennsylvania EDC(s)
          ECAR in the ratio specified in the December Special Content
          Declaration for ECAR and in an amount equal to 95-105% of the
          Designated Green Mountain Customer Load in ECAR, each calendar year or
          within 4 months after the end of the calendar year;

     (e)  Delivers Wholesale Products to retail or wholesale customers in
          Pennsylvania EDC(s) in ECAR other than Green Mountain or Designated
          Green Mountain Customers in the ratio specified in the December
          Special Content Declaration and in an amount equal to 95-105% of the
          Designated Green Mountain Customer Load in ECAR, each calendar year or
          within 4 months after the end of the calendar year where Supplier does
          not transfer to such other customer(s) the rights to claim the
          environmental attributes that differentiate such Wholesale Products
          from Undifferentiated System Power; or

     (f)  Any combination of (d) or (e).

     Supplier will deliver Wholesale Products within 4 months of the end of the
calendar year that in the aggregate equal 100% of the Designated Green Mountain
Customer Load as described in the adjusted Special Content Declaration issued in
January and in a final Special Content Declaration in February, even though each
Wholesale Product may be within the 95 - 105% range.

     Any delivery to other customers will not diminish Supplier's obligation to
provide Full Requirements Service.

     Any deliveries after the end of the calendar year as described above will
not be used to satisfy Wholesale Product delivery obligations in the current
year.

     C.  Supplier will develop and deliver to Green Mountain a list of potential
generating units for Wholesale Products ("Candidate List") within 30 days of
execution of this Agreement.  Green Mountain and Supplier will review resources
on the Candidate List with environmental leaders/groups selected by Supplier and
Green Mountain ("Supplying Resources").  Supplier will give due consideration to
any objections that such environmental leaders/groups may

                                                                    Confidential


have to any Supplying Resources and will use reasonable efforts to obtain energy
from other than objectionable Supplying Resources provided that there are no
adverse economic or operation effects on Supplier. From the list of Supplying
Resources, Supplier, in its sole discretion may select any combination of the
Supplying Resources to supply the Wholesale Products. The foregoing shall not
require Supplier to have firm contracts with Supplying Resources for any amount
of capacity or energy and Supplier may dispatch a Supplying Resource in a way
that best meets the interests of Supplier provided that the obligations of
Supplier with respect to Wholesale Product delivery and Wholesale Product
verification are met. Supplier may at any time add Supplying Resources,
consistent with the review process described previously in this section.

     D.  Within 15 days following the end of each calendar quarter, Supplier
will provide Green Mountain with a written report identifying its use, expressed
volumetrically, of Supplying Resources that it (a) has used during the prior
calendar quarter and (b) expects to use during the current calendar quarter, to
satisfy its Wholesale Product delivery obligations. In the event that any such
report does not reflect the use or intended use of the Supplying Resources in
such relative quantities as required to meet the Supplier's Wholesale Product
delivery obligations, Green Mountain shall have the right to demand written
assurance from Supplier that it will meet its Wholesale Product delivery
obligations. Supplier shall provide such assurance to Green Mountain in writing
within (30) days of such request. If Supplier does not provide assurance, which
is reasonably satisfactory to Green Mountain, Green Mountain upon written notice
to Supplier shall have the right to procure Wholesale Product from other
suppliers if Supplier is not currently supplying such Wholesale Product as
required by this Agreement until Supplier provides such assurances or begins
supply of such Wholesale Products as required by this Agreement. Supplier will
be responsible for incremental costs as described in Section 7(b) and (c),
incurred by Green Mountain in such volumes as may be necessary to meet the
Supplier's Wholesale Product delivery obligation.

     E.  If at any time during the term of this Agreement it is determined that
a Supplying Resource no longer meets the requirements for supply under this
Agreement, such non-complying Supplying Resource may become ineligible for
supply of capacity and energy hereunder provided that the following conditions
are met. If the independent third party evaluator (as described in Paragraph F)
makes a determination that a Supplying Resource's generation does not meet the
requirements as described in this Agreement, then such Supplying Resource shall
be removed or its use limited to that which it is qualified to supply. If
Supplier has entered into a term arrangement for supply of Wholesale Products
from the Supplying Resource that has been removed or

                                      -11-

                                                                    Confidential


limited for reasons other than failure to meet the Renewable Resources
definition, Supplier shall be permitted to continue to purchase Wholesale
Products from such Supplying Resource for the remainder of the Measurement
Period or until the end of the term of Supplier's supply agreement with such
Supplying Resource, whichever is less.

     F.  Supplier shall maintain and make available for independent third party
verification, on an annual basis, records that document the delivery of energy
from Supplying Resources to the respective Energy Delivery Points and document
that the Wholesale Product requirements are fulfilled.  Any such independent
third party shall be selected by Supplier and shall be subject to approval by
Green Mountain which shall not be unreasonably withheld.  If the parties are
unable to agree upon such independent third party evaluator, an evaluator shall
be selected pursuant to paragraph 23, Dispute Resolution.  Any independent
evaluator shall perform its verification under the terms of a confidentiality
agreement and shall not disclose or discuss any of the information revealed in
the verification process with any party other than Green Mountain and Supplier.
Supplier shall bear the cost of the verification.  Green Mountain and Supplier
shall cooperate reasonably to meet regulatory requirements to disclose the
characteristics of Retail Products sold to retail customers in the Commonwealth
of Pennsylvania during the term of this Agreement to the extent required by
applicable environmental or other regulatory laws.

     G.  Green Mountain and Supplier shall comply, and shall maintain records to
evidence compliance with this Agreement and any applicable laws governing the
transactions contemplated by this Agreement. Green Mountain and Supplier shall
have the right to audit the other party's records associated with this section
through a mutually agreed upon third party to assure compliance with the
Agreement, all in accordance with the mechanism for selecting such independent
evaluator described above.

9.   Delivery:
     Green Mountain shall take title to the energy delivered under this
Agreement at the Energy Delivery Points. Although title to the energy delivered
hereunder will pass to Green Mountain at the Energy Delivery Points, Supplier
shall be responsible for scheduling, and imbalance costs up to the Designated
Green Mountain Customer's meter. Supplier shall bear all risk of loss before the
Energy Delivery Points and Green Mountain shall bear all risk of loss (excluding
Distribution Loss Factors) beyond the Energy Delivery Points. Except as
otherwise provided above, each party shall be responsible for all costs, damages
and other liabilities for energy delivered hereunder on their respective sides
of the Energy Delivery Points.

10.  Charges:
     For Wholesale Products, Green Mountain will pay Supplier an amount as
defined and described below for energy associated with each resource, times the
energy measured at the Designated Green Mountain Customer meters. For purposes
of payment, all deliveries will be deemed to be Wholesale Products in the ratios
specified in the Special Content Declaration for such month. Green Mountain
shall be responsible for paying Supplier these amounts regardless of whether
Green Mountain collects any revenues from the Designated Green Mountain
Customers.

     (a)  A base charge ("Base Charge") will apply, as follows, for each
          Wholesale Product to cover all costs associated with Full Requirements
          Service, except for PJM Network Transmission Service.  To the extent
          that Green Mountain is charged or receives credit from the ISO or
          EDC(s) for under or over deliveries, such costs shall be deducted from
          Supplier's charges or credits added to Supplier's charges as the case
          may be.

          Clean Power Resources delivered in PJM:    $ ***
          Clean Power Resources delivered in ECAR:   $ ***

Base Charge Adders are as follows:

     (a)  All costs associated with PV energy plus an administrative fee for
handling the assignment of PV energy to Supplier and incorporation thereof into
the Wholesale Products will be applied based upon actual energy content at:
$***.

     (b)  For other than the PJM Network Integration Transmission Service Charge
which Green Mountain has agreed to reimburse Supplier, if an EDC or ISO
allocates charges for services required prior to the Energy Delivery Point(s) to
Green Mountain, Supplier will reimburse Green Mountain. If an EDC or ISO
allocates charges for services required after the Energy Delivery Point(s) other

reimburse Supplier.

     (c)  PJM Network Integration Transmission Service Charge if incurred by
Supplier.

     (d)  If Green Mountain does not purchase at least *** (or as reduced by the
same ratio as reduction pursuant to Paragraph 5(D) or (E)) through April 2000,
Green Mountain shall pay Supplier a reservation fee of $*** for each MWh not
purchased and shall be payable on or before May 31, 2000.

          If Supplier exercises its option to cease acceptance of allocation of
additional Load Profiled Retail Customers as provided in Paragraph 3(C) no
reservation fee will be owed.

          This paragraph (d) shall not limit Green Mountain's liability for
failure to purchase Full Requirements Service.

11.  Taxes and Franchise Fees:
     Each Party shall be responsible for paying any taxes or franchise fees
imposed by any governmental entity having jurisdiction over such Party.
Specifically, Green Mountain shall be responsible for collecting and submitting
to the applicable governmental authority any sales tax imposed on, or collected
from Designated Green Mountain Customers, and franchise fees or taxes imposed
upon Green Mountain related to the delivery of Wholesale Products and
Undifferentiated System Power to the Designated Green Mountain Customers, and
any other taxes or franchise fees of whatever nature that are imposed on Green
Mountain from and after the delivery of the Wholesale Products and
Undifferentiated System Power to the Energy Delivery Points (the "Green Mountain
Taxes"). Supplier shall be responsible for collecting and submitting to the
applicable governmental authority any wholesale sales tax, franchise fees or
taxes, and any other taxes or franchise fees of whatever nature that are imposed
on Supplier before the delivery of the Wholesale Products and Undifferentiated
System Power to the Energy Delivery Points (the "Supplier Taxes"). Each Party
shall indemnify and hold the other Party harmless from and against any liability
associated with the indemnifying party's failure to comply with this paragraph.

12.  Billing:
     After commencement of deliveries, Supplier shall bill Green Mountain on a
monthly basis, no earlier than the first day of the month following the month of
service ("Invoice Month") and using best efforts to bill on or before the tenth

                                                                    Confidential

(10th) day of the Invoice Month, based upon an estimation of the Base Charge and
Base Charge Adders (based on energy in MWh) scheduled to the ISO/EDC on behalf
of Green Mountain, adjusted for ISO/EDC transmission and distribution losses, as
applicable (collectively "Estimated Charges"), as described below. The monthly
invoice shall be paid in full within 20 days of the date of the invoice.  In
anticipation of the need to pay such bills, Green Mountain will utilize an
independent third party(ies) to receive all payments from the Designated Green
Mountain Customers into a separate account in the name of and for the benefit of
Supplier.  The Supplier shall be entitled to receive the foregoing revenues up
to the amount of the Estimated Charges for the current billing period plus or
minus any adjustments based on Actual Meter Load.  Such arrangements with the
independent third parties shall be satisfactory to Supplier, which shall not be
unreasonably withheld.  Green Mountain grants Supplier a security interest in
these receivables  and will execute and file Security Agreement(s), Financing
Statement(s) and such other documents as Supplier may request to maintain and
perfect its security interest.  Green Mountain shall instruct said independent
third party(ies) to transfer the funds so segregated into the Supplier's account
on a weekly basis.  All amounts so transferred  shall  be credited against the
amount due from Green Mountain under Supplier's monthly bill.

     In addition to the other security provisions, on or before December 24,
1998, Green Mountain will provide Supplier with, and maintain, a letter of
credit or cash deposit, at its option, equal to Supplier's January 1999
receivables based upon the Green Mountain forecast pursuant to Paragraph
13(a)(ii) and the Special Content Declaration. The letter of credit shall be
updated five days prior to the commencement of service for the next calendar
month to equal the amount of the forecasted receivables for the next month or
the current month which ever is more. Any such letter of credit shall be issued
or confirmed by a bank which is acceptable to Supplier; shall be in a form
acceptable to Supplier; shall be irrevocable in Supplier's favor; and shall be
fully enforceable and not the subject of any action to restrain payment
thereunder. After six consecutive months of satisfactory lockbox operation,
timely payment history by Green Mountain, and full payment of Supplier's
invoices for the first six months, Green Mountain shall no longer be required to
provide the letter of credit or cash deposit as described in this paragraph.

     Should Green Mountain fail to comply with the foregoing lockbox procedure
in any material respect, or fail to make any payment when due, Supplier may in
addition to any other remedy, provide Green Mountain with written notice of such
failure and, if Green Mountain fails to correct such

                                                                    Confidential


failure within six days after receipt of such notice, Supplier shall have the
right to require Green Mountain to provide and maintain security during the term
of this Agreement and until final payment is made, in the form, of cash or a
letter of credit at Green Mountain's option. Any such letter of credit shall be
issued or confirmed by a bank which is acceptable to Supplier; shall be in a
form acceptable to Supplier; shall be irrevocable in Supplier's favor; and shall
be fully enforceable and not the subject of any action to restrain payment
thereunder and in an amount equal to 60 days of Supplier's sales hereunder. Such
security shall be provided within 3 business days of Supplier's request.

     Bills which are not paid in full by Green Mountain when due shall
thereafter bear interest until paid at the rate of 1% per month or at the
maximum rate of interest allowed by law, whichever is less.

     Each month, Green Mountain shall notify Supplier of the Actual Metered Load
associated with the previous month's service, which shall be the basis for an
adjustment to the Estimated Charges under this Agreement.  Supplier shall credit
or charge Green Mountain appropriately during the next monthly billing to
account for this adjustment. Supplier shall have the right to audit Green
Mountain's records associated with the Actual Metered Load through a mutually
agreed upon third party.

13.  Customer Forecasts:
     Green Mountain expects that some EDCs will administer most of the forecast
requirements of Designated Green Mountain Customer Loads.  Where this is done,
the Supplier will work directly with the EDC, while keeping Green Mountain
informed of the status of its load.  Green Mountain will also supply
supplemental information, such as longer-term forecasts, beyond those expected
to be provided by the EDC.

     If scheduling services are not provided by the EDC:

     (a)  Green Mountain will then provide Supplier:

             (i) No later than the 15th day of each month, its best estimate of
          the energy required of Supplier to meet Designated Green Mountain
          Customer Load for each Wholesale Product, for each month of the
          succeeding Measurement Period.  Green Mountain will support and
          facilitate and will use best efforts to assist in the preparation of
          daily load forecasts by Supplier.

                                                                    Confidential


             (ii) Five working days prior to each calendar month, the total
          number of Designated Green Mountain Customers for each Customer Group,
          at the necessary level of disaggregation to match the Energy Delivery
          Points' requirements associated with the scheduling services provided
          by Supplier, by Load Profile-Type and Wholesale Product selected.
          Green Mountain will also provide average historical daily usage for
          the Designated Green Mountain Customers (based upon actual and
          estimated data) for each combination of location, Load Profile-Type,
          and Wholesale Product.

     (b)  Supplier shall prepare the final day ahead and hour ahead forecasts
required by the ISO/EDC for scheduling based on the information supplied by
Green Mountain in the foregoing Paragraph, and day-ahead updates of Load
Profiles and Distribution Loss Factors provided by the EDCs, and other supplier-
based information such as weather forecasts.

     Included in the above will be recognition of the decremental customer
counts by Load Profile-Type and Retail Product selected in the event that
Designated Green Mountain Customers are terminated or are returned to service by
the EDC for whatever reason. Green Mountain will notify Supplier at
approximately the same time that it notifies the EDC that a Designated Green
Mountain Customer is converting to another supplier, but in no event later than
forty-eight hours following Green Mountain's notice to the EDC.

     In all cases, the Supplier will make available to Green Mountain, in a
timely fashion (at least monthly), all documents pertaining to the Supplier's
scheduling or settlement of Designated Green Mountain Customer Loads for all ISO
and/or EDC transactions.

     To the extent that the Supplier has Green Mountain Load Profiles and
Distribution Loss Factors for each Energy Delivery Point for each day, that are
not easily accessible to Green Mountain, the Supplier shall provide to Green
Mountain this information, upon written request.

     Green Mountain shall be responsible for Reconciliation with the EDCs.

14.  Data Transfer:
     This Agreement contemplates the exchange of information and data necessary
to implement the schedules, delivery arrangements and other data and information
described herein. The Parties shall develop mutually agreeable standards for the
content and protocols for data transfer required

under this Agreement.

15.  Relationship of the Parties:
     The Supplier is a wholesale supplier to Green Mountain at the Delivery
Point(s).  Green Mountain is the retail Electric Generation Supplier ("EGS"),
certified by the Pennsylvania Public Utilities Commission, and as such will be
responsible, or contract with third parties, for all interactions with the
Designated Green Mountain Customers, including transmission and distribution
after the Energy Delivery Points, metering, billing and reconciliation.  Nothing
in this Agreement (1) creates a partnership, joint venture or any relationship
other than that of supplier-purchaser, (2) confers any right to Supplier to
influence pricing or other sales practices of Green Mountain as between Green
Mountain and the Designated Green Mountain Customers or any third party, or (3)
confers any right to Green Mountain to influence supply contracting or
scheduling practices of Supplier.

16.  Confidentiality:
     Neither party shall use for any purpose other than its performance of this
Agreement or disclose to any third party (other than such party's employees,
lenders, counsel, accountants or suppliers any non-public information designated
as confidential by the disclosing Party except as is necessary to perform this
Agreement the or in order to comply with any applicable law, order, regulatory
or exchange rule; provided each Party shall notify the other Party of any
proceeding of which it is aware that may result in disclosure, consult with the
other Party on the advisability of legally available steps to resist or narrow
such request and use reasonable efforts to prevent or limit the disclosure.  The
disclosing Party will inform the recipient of the confidential nature of the
information at the time of disclosure of any confidential information.  This
obligation shall survive for a period of three years after the termination of
this Agreement.  The Parties agree that unauthorized disclosure of confidential
information will cause irreparable injury for which money damages are inadequate
and, therefore, in addition to any other remedy, the disclosing Party shall be
entitled to injunctive relief or specific performance.

     No publicity concerning the relationship of the Parties shall be released
without the consent of both Parties.

17.  Governing Law:
     This Agreement and any service agreement hereunder shall be interpreted,
construed and enforced in accordance with the laws of the Commonwealth of
Pennsylvania or the laws of the United States of America,

whichever is applicable, as if executed and to be performed wholly within the
Commonwealth of Pennsylvania.

18.  Force Majeure:
     In the event either Party is rendered unable, by an event of force majeure,

to carry out wholly or in part its obligations under the provisions hereunder,
it is agreed that if such Party gives notice and full particulars of such event
of force majeure to the other Party as soon as practicable after the occurrence

of force majeure, other than the obligation to make payments then due or
   ----- -------
becoming due hereunder, shall be excused from the inception and throughout the
period of continuance of any such inability so caused, but for no longer period,
and such event of force majeure shall, as far as practicable, be remedied with
                  ----- -------
all reasonable dispatch.

     The term "force majeure" as employed herein shall mean physical or
               ----- -------
governmental causes of the kind not reasonably within the control of the Party
claiming suspension and which by the exercise of due diligence such Party could
not have prevented or is unable to overcome.  Such causes shall include
interruptions of firm transmission service relied on to make delivery, strikes,
labor difficulties, shutdowns in anticipation of strikes, accidents, equipment
breakdown, riots, fire, flood, wars, delays or interruptions in transportation,
failure of generating equipment, failure or threat of failure of facilities,
materially disruptive actions or failure to act of any government or government
agency (whether or not legal force and including without limitation any Court

cause or contingency of similar or dissimilar nature not reasonably within the
control of the party claiming such force majeure event, whether of the nature or
                                   ----- -------
subject matter herein enumerated or noted.  Nothing contained herein, however,
shall be construed to require a Party to prevent or settle a strike against its
will.  Economic hardship shall not constitute force majeure.

19.  Indemnification:

notwithstanding, Supplier's obligations under this Agreement towards any Green
Mountain Indemnitee are conditioned upon such Green Mountain Indemnitee
providing such cooperation as Supplier may reasonably request in connection with
its defense or settlement of the claim or suit against such Green Mountain
Indemnitee.

Description of Green Mountain's Special Content Declaration

January, 1999: Estimates are created for all of 1999. DTE is allocated 40%
customer share. January's declaration will be the residual blend (total minus
other suppliers) falling out from Green Mountain's expected product mix.
January's declaration will be used for billing purposes for January deliveries
(showing a weighting of the component rates).

February, 1999: Estimates may be updated. Better information for all months may
be available, including revised estimates of January volumes. The only figures
fixed are the percentages of the January declaration. If the January volumes
differed from forecast, the percentages declared times the revised volume would
constitute the revised January deliveries. The declaration for February would be
the sum of the revised requirements through February, less the revised
deliveries for January. The revised figures for the rest of the year allows for
the best calculation of the year-end aggregate requirement.

March, 1999: Estimates may be updated. Better information for all months may be
available, including EDC-declared January actuals. The percentages of the
January and February declarations are held constant. The declaration for March
would be the sum of the revised requirements through March, less the revised
deliveries for January and February.

                      FIRST AMENDMENT TO MASTER AGREEMENT

                    GREEN MOUNTAIN ENERGY RESOURCES L.L.C.

     This First Amendment to Master Agreement ("Amendment") is executed as of
November 25, 1998 by and between DTE-CoEnergy, L.L.C ("Supplier") and Green
Mountain Energy Resources L.L.C. ("Green Mountain") and, together with Supplier,
(the "Parties").

     The Parties are Parties to a Master Agreement dated September 11, 1998
("Agreement") and agree to amend the Agreement as follows:

     1.  Section 8B(b) is deleted and the following in inserted in lieu thereof:

         "(b)  Delivers Wholesale Products to retail or wholesale customers in
         PJM other than Green Mountain Customers in the ratio specified in the
         December Special Content Declaration and in an amount equal to 95-105%
         of the Designated Green Mountain Customer Load in PJM each calendar
         year or within 4 months after the end of the calendar year where
         Supplier does not transfer to such other customer(s) the rights to
         claim the environmental attributes that differentiate such Wholsesale
         Products from Undifferentiated System Power; or"

     2.  The first paragraph of Section 12, Billing, is deleted and the
         following is inserted in lieu thereof:

         "After commencement of deliveries, Supplier shall bill Green Mountain
         on a monthly basis, no earlier than the first day of the month
         following the month of service ("Invoice Month") and using best efforts
         to bill on or before the tenth (10th) day of the Invoice Month, based
         upon an estimation of the Base Charge and Base Charge Adders (for the
         energy in MWh) scheduled to the ISO/EDC on behalf of Green Mountain
         adjusted for ISO/EDC transmission and distribution losses, as
         applicable (collectively "Estimated Charges"). The monthly invoice
         shall be paid in full within 20 days of the date of the invoice. In
         anticipation of the need to pay such bills, Green Mountain will utilize
         an independent third party(ies) to receive all payments from the
         Designated Green Mountain Customers into a separate account in the name
         of and for the benefit of Supplier. The Supplier shall be entitled to
         receive the foregoing revenues up to the amount of the Estimated
         Charges for the current billing period plus or minus any adjustments
         based on Actual Meter Load. Such arrangements with the independent
         third parties shall be satisfactory to Supplier, which shall not be
         unreasonably withheld. Green Mountain grants Supplier a security
         interest in these receivables and will
<PAGE>

         execute and file Security Agreement(s), Financing Statement(s) and such
         other documents as Supplier may request to maintain and perfect its
         security interest. Green Mountain shall instruct said independent third
         party(ies) to transfer the funds so segregated into the Supplier's
         account on a weekly basis. All amounts so transferred shall be credited
         against the amount due from Green Mountain under Supplier's monthly
         bill."

     3.  Except as hereinbefore set forth, the Agreement remains unchanged.

     The Parties are Parties to a Master Agreement dated September 11, 1998, as
amended, ("Agreement") and agree to amend the Agreement as follows:

1.   The following defined term is added to Paragraph 1:

     "SETTLEMENT PROCESS:   The process of settling with the EDC for the charges
or credits associated with volumetric differences between the scheduled
deliveries and the Designated Green Mountain Customers' actual use."

2.   The following is added to the end Paragraph 5B:

     Green Mountain shall allocate Supplier a percentage share of the total
aggregate energy requirements of its' Load Profiled Retail Customers for each
ECAR EDC, representing one hundred percent (100%) of incremental customer
additions, until such time as Supplier has been allocated the minimum percentage
specified in Paragraph 5A as may be limited by Paragraph 5C.  Such allocation
shall commence by May 1 or as soon as thereafter as practical and continue until
all EDC's allow Green Mountain to utilize multiple suppliers of Wholesale
Products.  An example of the allocation is set forth in Exhibit A to the Second
Amendment.

     Sixty days after the first billing month in which an EDC allows Green
Mountain to use multiple suppliers of Wholesale Products the percentage share
referred to in the preceding paragraph will be converted to Designated Green
Mountain Customers and which will be included in the Customer Group
corresponding to the date they began to receive service pursuant to the
preceding paragraph

     Green Mountain shall be responsible for the Settlement Process for each EDC
where the Designated Green Mountain Customers are served by more than one
supplier of Wholesale Products.  Green Mountain's responsibility for the
Settlement Process shall last until 60 days after the first billing month in
which such EDC allows Green Mountain to use multiple suppliers of Wholesale
Products at which time the Supplier shall resume responsibility for the
Settlement Process.  Green Mountain shall allocate Settlement Process credits
and charges among all of its Wholesale Product suppliers serving Load Profiled
Retail Customers in each EDC based on the percentage share of the total
aggregate energy requirements served by each such supplier.  Any charge or
credit to the

          particular Page of the Yahoo Properties.

3.   Green Mountain Button.
     ---------------------

reasonable commercial efforts, and, if not, on a DMA basis if technically
feasible upon reasonable commercial efforts.  Yahoo acknowledges that merchant

          Jersey on a zip code basis if technically feasible upon reasonable
          commercial efforts, and, if not, on a DMA basis if technically
          feasible upon reasonable commercial efforts); and (ii) to each Yahoo
          Mail user that clicks-through the Green Mountain Button (for clarity,
          the e-mails delivered pursuant to this clause (ii) shall not count
          against the number of e-mails that Yahoo shall deliver pursuant to
          clause (i) of this Section 4.1). The text of the Green Mountain E-Mail
          in either case shall be provided by Green Mountain and shall be
          subject to Yahoo's approval and consistent with Yahoo's policies and
          guidelines for such messages. Yahoo shall use reasonable commercial
          efforts to ensure that no more than one (1) Green Mountain E-Mail
          referenced in clause (i) of this Section 4.1 is delivered to a Yahoo
          Mail user during each four (4) month period of the Term. In addition,
          Yahoo agrees to not send such Green Mountain E-Mail to any individual
          identified by Green Mountain as a current Green Mountain customer.

5.   Implementation.

          Mountain Links.

     5.2  Green Mountain shall promptly provide Yahoo all URLs, URL formats (as
          applicable), content, and other materials necessary for Yahoo to
          provide the Green Mountain Links. All content and material contained
          in the Green Mountain Links are subject to Yahoo's approval and must
          comply with all applicable federal, state and local laws, rules and
          regulations, including, without limitation, consumer protection laws
          and rules and regulations governing product claims,

          truth in labeling, and false advertising.

     5.3  Green Mountain hereby grants to Yahoo a non-exclusive, worldwide,
          fully paid license to use, reproduce and display the Green Mountain
          name and logo (i) to indicate the location of the Green Mountain Links
          as set forth herein and (ii) in connection with the marketing and
          promotion of Green Mountain in the Yahoo Properties.

     5.4  In no event shall any Page on the Green Mountain Site to which users
          click-through directly from any Green Mountain Link, contain graphic
          or textual hyperlinks, banner advertisements or promotions of any
          Yahoo competitors, including, but not limited to: ***

     5.5  Green Mountain shall place a Yahoo graphic link on those Pages of the

          manner approved by Yahoo (b) contain the Yahoo name and logo as
          provided by Yahoo and (c) directly link the user back to the Page on
          the Yahoo Properties from which the User originated.

     5.6  The Green Mountain Site shall comply with the scale, speed and
          performance requirements mutually agreed upon by the parties but in no
          event less than that which is reasonably equivalent (taking into
          account volume differences) to the Yahoo Main Site.

6.   Rights of First Presentation.
     ----------------------------

     6.1  Within *** prior to the expiration of the Term, Yahoo will provide
          written notice to Green Mountain in the event that Yahoo, at its sole
          discretion, elects to extend this advertising and promotion program.
          Yahoo shall describe Yahoo's reasonable business requirements for the
          extension in its written notice to Green Mountain. The parties will
          use good-faith efforts to negotiate and execute a written extension to
          this Agreement under reasonable terms and conditions. If Green
          Mountain declines to commence negotiations with Yahoo within *** after
          receiving such written notice from Yahoo, or if the parties fail to
          reach agreement within *** following the commencement of good faith
          negotiations (or such later date as is agreed by the parties), Yahoo
          may offer the opportunity to any third party. Under no circumstances
          shall the foregoing right of first presentation be deemed to restrict
          Yahoo's ability to extend other merchant positions in relating to this
          advertising and promotion program to third parties.

     6.2  This advertising and promotion program is designed to apply to
          residents of California, Pennsylvania and New Jersey. As Green
          Mountain energy services become available in additional states, Green
          Mountain shall have *** this advertising and promotion program to
          include such new states on terms mutually agreed upon by the parties.
          For clarity, such an extension shall include advertising and
          promotions similar in scope and placement to those

          described herein, at prices to be determined by the parties at the
          time of such extension.

7.   Page Views.
     ----------

     7.1  With respect to the Green Mountain Banners and Buttons, Yahoo shall
          deliver no less than *** Page Views. Yahoo shall use commercially
          reasonable efforts to ensure that such Page Views are delivered evenly
          to unique users in accordance with Yahoo's standard advertising
          delivery system procedures.

     7.2  Yahoo will use reasonable commercial efforts to deliver such Page
          Views as follows: *** Page Views of the Green Mountain Banner; and ***
          Page Views of the Green Mountain Button. Further, Yahoo shall use
          reasonable commercial efforts to ensure that the Page Views of the
          Green Mountain Banner referenced in this Section 7.2 are allocated
          approximately as follows: nineteen (19%) percent to New Jersey
          residents, thirty-six percent (36%) to Pennsylvania residents, and
          forty-five percent (45%) to California residents (in each case as such
          residents are further defined in Section 3.1); provided that if
          deregulation on acceptable terms in New Jersey is delayed by more than
          one month, on 30 days notice Yahoo shall shift a commensurate amount
          of Green Mountain Banners to California and Pennsylvania subject to
          availability. Notwithstanding anything to the contrary on this Section
          7.2, Yahoo's Page View obligations are with respect to the program as
          a whole as set forth in Section 7.1 and Yahoo shall not be in breach
          of this Agreement for failure to deliver the number of Page Views in
          either of the specific areas set forth in this Section 7.2.

     7.3  In the event that Yahoo fails to deliver the number of Page Views
          referred to in Section 7.1 above by the expiration of the Term, Yahoo
          will "make good" the shortfall by extending its obligations under
          Sections 2 and 3 in the areas of the Yahoo Main Site set forth therein
          (or similar inventory) beyond the end of the Term until such Yahoo
          Page View obligation is satisfied, provided that such obligation shall
          be satisfied within six months from the end of the Term. The
          provisions set forth in this Section 7.3 set forth the entire
          liability of Yahoo, and Green Mountain's sole remedy, for Yahoo's
          breach of its Page View obligations set forth in this Section 7.

     7.4  Yahoo will treat Green Mountain on a basis reasonably equivalent to
          its other Premier Merchants in terms of placement of Green Mountain
          Banners and Buttons on the Yahoo Properties and location on specific
          pages, taking into account the unique characteristics of this program.
          Throughout the Term, the parties shall discuss in good faith mutually
          beneficial adjustments to this advertising and promotion program,
          subject in all cases to Yahoo's available advertising inventory.

     7.5  Yahoo shall provide Green Mountain access twenty-four hours a day,

          (ii) *** no less than seven days prior to the Launch Date, (iii) ***
          ninety days after the Launch Date; (iv) *** one hundred eighty days
          after the Launch Date; and (v) *** two hundred seventy days after the
          Launch Date.

     8.2  Referral Fee.  In addition to the compensation described in Section
          ------------

          equal to *** for each new energy services account opened through the
          promotions provided by Yahoo under this Agreement (the "Referral
          Fee"). Such payments shall be made within ten (10) days of the end of
          the calendar quarter for which such payments apply. Under no
          circumstances, however, shall the Referral Fee exceed a total of four
          hundred thousand dollars ($400,000) for the Term. For purposes of this
          Section 8.2, the first calendar quarter of the Term shall be deemed to
          be begin as of the Effective Date and end as of June 30, 1999.

     8.3  Payment Information.  All payments herein are non-refundable and non-
          -------------------

          ACH electronic payment into Yahoo's main account pursuant (if by wire
          transfer) to the wire transfer instructions set forth on Exhibit B.
                                                                   ---------

     8.4  Late Payments.  Any portion of the above payments which has not been
          -------------
          paid to Yahoo within ten (10) days of the dates set forth above shall
          bear interest at the lesser of (i) one percent (1%) per month or (ii)
          the maximum amount allowed by law. Notwithstanding the foregoing, any
          failure by Green Mountain to make the payments specified in Sections
          8.1 and 8.2 on the dates set forth therein shall constitute a material
          breach of this Agreement.

9.   Termination.
     -----------
     9.1  Term.  This Agreement shall commence upon the Effective Date and,
          ----
          unless terminated as provided herein, shall remain in effect for the
          Term.

     9.2  Termination by Either Party with Cause.  This Agreement may be
          --------------------------------------
          terminated at any time

          written notice to the other party of such other party's breach of any
          of its obligations under this Agreement in any material respect (ten
          (10) days in the case of a failure to pay), which breach is not
          remedied within such notice period. In the event that Yahoo provides a
          notice of termination under clause (ii) above, Yahoo shall have the
          right to suspend its performance under this Agreement for the notice
          period unless and until the breach is fully remedied by Green Mountain
          prior to the expiration of the notice period.

     9.3  Survival.  The provisions of Sections 7.3, 8, 10-14, and this 9.3

          Merchants."

          harmless Yahoo and its employees, representatives, agents and

          blockade, legal prohibition, governmental action, riot, insurrection,
          damage, destruction or any other similar cause beyond the control of

            party.

     2.   Except as set forth in this Section 2, all Confidential Information
shall be in tangible form and shall be marked as Confidential or proprietary
information of the disclosing party.  If the Confidential Information is
disclosed orally or visually, it shall be identified as such at the time of
disclosure and confirmed in a writing to the recipient within thirty (30) days
of such disclosure.

     3.   Each of the parties agrees that it will not make use of, disseminate,
or in any way disclose any Confidential Information of the other party to any
person, firm or business, except to the extent necessary for negotiations,
discussions, and consultations with personnel or authorized representatives of
the other party and any purpose the other party may hereafter authorize in
writing.  Each of the parties agrees that it shall disclose Confidential
Information of the other party only to those of its employees who need to know
such information and who have previously agreed, either as a condition to
employment or in order to obtain the Confidential Information, to be bound by
terms and conditions substantially similar to those of this Agreement.

     4.   There shall be no liability for disclosure or use of Confidential
Information which is (a)  in the public domain through no fault of the receiving
party (b) rightfully received from a third party without any obligation of
confidentiality, (c) rightfully known to the receiving party without any
limitation on use or disclosure prior to its receipt from the disclosing party,
(d) independently developed by the receiving party (e) generally made available
to third parties without any restriction on disclosure, or (f) communicated in
response to a valid order by a court or other governmental body, as otherwise
required by law or governmental regulation, or as necessary to establish the
rights of either party under this Agreement (provided that the party so
disclosing has provided the other party with a reasonable opportunity to seek
protective legal treatment for such Confidential Information).

      5.   "Residual Information" shall mean any Confidential Information of the
disclosing party which may be retained in intangible form in the minds of those
individuals of the receiving party who have had proper access to such
Confidential Information.  Notwithstanding anything else in this Agreement, the
receiving party shall be free to use any Residual Information for any purpose
whatsoever, including, without limitation, the development of its own products,
or business, provided that such party shall not be entitled to disclose Residual
Information to any third parties unless such disclosure is in the course of, or
as part of, any disclosure of its own products or business or their development.

      6.  Each of the parties agrees that it shall treat all Confidential
Information of the other party with the same degree of care as it accords to its
own Confidential Information, and

each of the parties represents that it exercises reasonable care to protect its
own Confidential Information.

      7.  Each of the parties agrees that it will not modify, reverse engineer,
decompile, create other works from, or disassemble any software programs
contained in the Confidential Information of the other party unless otherwise
specified in writing by the disclosing party.

      8.  All materials (including, without limitation, documents, drawings,
models, apparatus, sketches, designs and lists) furnished to one party by the
other, and which are designated in writing to be the property of such party,
shall remain the property of such party and shall be returned to it promptly at
its request, together with any copies thereof.

      9.  This Agreement shall govern all communications between the parties
that are made during the period from the effective date of this Agreement to the
date on which either party receives from the other written notice that
subsequent communications shall not be so governed, provided, however, that each
party's obligations under Sections 2 and 3 with respect to Confidential
Information of the other party which it has previously received shall continue
unless and until such Confidential Information falls within Sections 4 or 5.
Neither party shall communicate any information to the other in violation of the
proprietary rights of any third party.  Neither party acquires any licenses
under any intellectual property rights of the other party under this Agreement.

The following information will be included in the Registration Statement:

According to the Worldwatch Institute (1) (2) (3):

  .  Atlantic Richfield CEO Michael Bowlin sees ARCO's large holdings of
     natural gas playing a key role in the transition from a carbon-based
     energy economy to one based on hydrogen.

  .  Royal Dutch Shell has announced a committment of $500 million to
     renewable energy sources.

Another recent Worldwatch publication states (1):

  . . . [There] is an exciting alternative economic model that promises a
  better life everywhere without destroying the earth's natural support
  systems. The new economy will be powered not by fossil fuels, but by
  various sources of solar energy and hydrogen . . . Instead of a throwaway
  economy, we will have a reuse/recycle economy.
