Dear Real Goods Shareowner:

You are cordially invited to attend a special meeting of the shareowners of Real
Goods Trading Corporation, a California corporation (Real Goods) to be held at
11:00 a.m. on               , 2001 at the offices of the company (3440 Airway
Drive, Santa Rosa, California).  At that special meeting, you will be asked to
consider and vote upon a proposal to approve a merger agreement pursuant to
which Real Goods will merge with a wholly-owned subsidiary of Gaiam, Inc., a
Colorado corporation (Gaiam)

Under the merger agreement, you will receive one (1) share of Gaiam Class A
common stock for each ten (10) shares of Real Goods common stock that you own.
In addition, you will be entitled to can receive a gift certificate allowing you
to purchase $1 of products from the Gaiam or Real Goods catalogs, stores or
Internet sites up to a total of $100 per shareowner.   Gift certificates will
also be issued in lieu of fractional shares.  Real Goods' shares are traded on
the NASDAQ Small Capitalization Market under the symbol RGTC and on the Chicago
Stock Exchange under the symbol RGT.  Gaiam's shares are traded on the Nasdaq
National Market System under the symbol GAIA.

In recent years we have discovered the importance of attaining critical mass to
achieve appropriate efficiencies in scale.  We have attempted to do so both
through redesign and refocusing of our catalogs as well as through adopting and
revising a retail strategy and entering into a strategic relationship with Whole
Foods Markets.  Despite all of those activities, it is now clear to your
management that the best way to carry forward the Real Goods mission of
sustainable living is to join forces with Gaiam and its catalogs, Internet site
and retail presence to build the Real Goods and Gaiam brands together.  We are
looking forward to that endeavor.

Your Board of Directors has unanimously determined that the merger agreement is
advisable, fair and in the best interest of Real Goods and its shareowners, and
has unanimously approved the merger agreement; your Board of Directors
unanimously recommends that you vote "For" the approval of the merger agreement.
This is an important decision for you as a Real Goods shareowner.  We therefore
encourage you to read carefully the accompanying document which provides
detailed information about the proposed merger and includes a copy of the merger
agreement as an annex.

The merger cannot be completed unless we obtain the approval of the holders of a
majority of Real Goods common stock.  YOUR VOTE IS VERY IMPORTANT.  Whether or
not you plan to attend the special meeting, please take the time to vote by
completing and mailing the enclosed proxy card to us.  If you are in support of
the merger, all you need to do is sign the proxy card and send it in.  Failure
to vote, or to instruct your broker how to vote any shares held for you in your
broker's name, will have the same result as a vote against approval of the
merger agreement.

I have greatly enjoyed working with all of our shareowners over the years,
appreciate all of your kind support and look forward to continuing to work with
you as I will be continuing on as President of the Real Goods division of Gaiam.
Together we can continue to work towards

implementation of our mission of ensuring a sustainable future for our children.
Thank you for taking the time to vote your proxy card.


                              Sincerely,


                              John Schaeffer

  A:  Your broker will not be able to vote your shares without instructions from
      you. You should instruct your broker to vote your shares, following the
      directions provided by your broker.

  Q:  Should I send in my stock certificates now?

  A:  No. We will send instructions to Real Goods shareholders on how to
      exchange their stock certificates for Gaiam stock after completion of the
      merger.

  Q:  What happens to my future dividends?

  Q:  When do you expect to complete the merger?

  A:  We are working to complete the merger as soon as possible. We hope to
      complete the merger shortly after the special shareholders' meeting, if we

      other conditions to the merger agreement have been satisfied.

  This summary contains selected information from this proxy
statement/prospectus and may not contain all of the information that is
important to you. To understand the merger more fully and for a more complete
description of the legal terms of the merger, you should read this entire
document carefully, including the Annexes, and the documents to which we refer.
A list of documents that we incorporate by reference appears below under the
heading "Where You Can Find More Information." In this proxy
statement/prospectus, "Real Goods" refers to Real Goods Trading Corporation and
"Gaiam" refers to Gaiam, Inc. and the "combined company," "we," "our," or "us"
refers to the combined company following the merger.


The Companies

Gaiam, Inc.
360 Interlocken Blvd., Suite 300
Broomfield, Colorado 80021
Telephone:  (303) 464-3600

Gaiam is a multi-channel lifestyle company marketing to customers who value the
environment, personal development and a healthy lifestyle.

Real Goods Trading Corporation
3440 Airway Drive
Santa Rosa, California  95403
Telephone: (707) 542-2600

Real Goods is a multi-channel marketer of environmental and renewable energy
products.

Reasons for the Merger

  The Real Goods Board of Directors believes that the merger will, among other
things:

  .  Compliment Gaiam's brand by adding the brand and relationships of Real
     Goods, a pioneer in the environmental, healthy living and renewable energy
     markets for many years.

  .  Provide the combined company with a broader customer base.

  .  Achieve significant operating synergies and economies of scale, including
     elimination of certain duplicative costs, including: sales/ marketing
     costs, company-wide operational functions and public company fees.

  .  Enable Real Goods shareholders to participate in the future growth
     potential of the combined company and share in any cost reduction and
     revenue enhancements which may be realized as a result of the merger.

  .  Provide the combined company with a wider shareholder base, float and
     greater liquidity.

  .  Enable Real Goods to take advantage of Gaiam's management team, thereby
     reducing the need to attract and retain employees in the highly competitive
     Northern California market.

  .  Enable Real Goods to take advantage of the larger resources of the combined
     company and more quickly advance its mission to promote and inspire an
     ecologically sustainable future than it could on its own.

Recommendation to Real Goods Shareholders  (see page    )

  The Real Goods Board believes that the merger is in the best interest of Real
Goods and its shareholders and unanimously recommends that you vote FOR the
proposal to approve the merger agreement providing for the merger.

  John Schaeffer and WholePeople.com, Inc., who together own approximately 53.7%
of Real Goods outstanding common stock, have already agreed to vote in favor of
the merger--which will result in Real Goods obtaining the required shareholder
approval of the merger.  See "--Voting Agreements."

Record Date; Voting Power
(see pages    and     )

  You are entitled to vote at the special meeting if you owned shares of Real
Goods common stock as of         , 2000, which is the record date for the
meeting.

  On November 15, 2000, there were 4,814,242 shares of Real Goods common stock
outstanding.  For each share of Real Goods common stock you owned on        ,
2000, the record date, you will have one vote at the special meeting.

Shareholder Vote Required (see page     )

  The merger and the merger agreement must be approved by the holders of a
majority of all outstanding shares of Real Goods common stock entitled to vote
at the special meeting.

Share Ownership of Management and  Directors  (see page     )

  On      , 2000, the record date for the special meeting of Real Goods
shareholders, directors and executive officers of Real Goods and their
affiliates owned and were entitled to vote 1,784,014 shares of Real Goods common
stock, or approximately 37.1% of Real Goods common stock outstanding on that
date.

  John Schaeffer and Wholepeople.com, a  shareholder of Real Goods, have entered
into voting agreements under which they have agreed to vote their shares in
favor of the proposal to approve the merger agreement and the merger. Together
they own approximately 53.7% of the outstanding Real Goods shares, which is
sufficient to approve the merger.  Each of the other directors and executive
officers of Real Goods intend to vote their shares in favor of the proposal to
approve the merger agreement and the merger.

The Merger

  We have attached the merger agreement as Annex A to this proxy
statement/prospectus.  We encourage you to read the merger agreement because it
is the legal document that governs the merger.

What Real Goods Shareholders Will Receive in the Merger  (see page    )

  As a result of the merger, Real Goods shareholders will receive 1 share of
Gaiam Class A common stock in exchange for every 10 shares of Real Goods common
stock that they own.  In addition, Gaiam will provide to each Real Goods
shareholder who elects to receive it a $1 gift certificate to purchase Gaiam's
and Real Goods' products for each Real Goods common share exchanged in the
merger, up to a maximum of $100 per shareholder.  Gaiam will not issue any
fractional common stock in the merger.  Instead, Real Goods common shareholders
will receive $1 in additional Gaiam gift certificates for each $1 (rounded up to
the nearest whole dollar) in market value of fractional Gaiam Class A shares to
which such holder would otherwise have been entitled had fractional shares been
issued.

  For example, if you own 25 shares of Real Goods common stock immediately prior
to the merger, and the price of Gaiam Class A common stock is $     per share
(the last reported sales price on the Nasdaq National Market on    , 2000), then
you will receive 2 shares of Gaiam Class A common stock based on the exchange


                                       4
<PAGE>

ratio and a $    gift certificate in exchange for the remaining 5 shares of Real
Goods common stock and in lieu of fractional shares (in addition to the $25 gift
certificate you will also receive if you so elect).

Ownership of Gaiam After the Merger

  Gaiam will issue approximately 481,424 shares of Class A Common Stock to Real
Goods shareholders in the merger.  Real Goods shareholders will own
approximately 8.1% of the outstanding Gaiam Class A common stock immediately
after the merger.  This information is based on the number of shares of Gaiam
Class A common stock and Real Goods common stock outstanding as of November 15,
2000, and does not take into account stock options issued by Gaiam or Real
Goods.

Material Federal Income Tax Consequences  (see pages __ and __)

  We intend that the merger qualify as a "tax-free reorganization" for federal
income tax purposes.  If the merger qualifies as a tax-free reorganization,
holders of Real Goods common stock will generally not recognize any gain or loss
for federal income tax purposes on the exchange of their Real Goods common stock
for Gaiam Class A common stock in the merger, except for (i) any gain or loss
recognized in connection with any gift certificates received in lieu of
fractional shares and (ii) any gain recognized in connection with any additional
gift certificates that a shareholder elects to received in the merger. The
companies themselves, as well as current holders of Gaiam Class A common stock,
will not recognize gain or loss as a result of the merger.

  The federal income tax consequences described above may not apply to all
holders of Real Goods common stock.  Your tax consequences will depend on your
own situation.  You should consult your tax advisor so as to fully understand
the tax consequences of the merger to you.

Appraisal or Dissenters' Rights (see page __)

If the merger is completed, holders of Real Goods' common stock entitled to vote
at the Real Goods' special meeting who do not vote in favor of the merger
agreement and who also comply with certain procedures and requirements of
California law will be entitled to dissent from the merger and exercise
dissenters' rights.  In accordance with these provisions, a Real Goods
shareholder who fully complies with the procedures set forth in Chapter 13 of
the California corporate law will have the right to receive cash, in lieu of
Gaiam Class A common stock, equal to the fair market value (excluding any
appreciation or depreciation as a consequence of the merger) of their Real Goods
common shares.  If Real Goods and the shareholder cannot agree on the fair
market value of the Real Goods common stock, the value will be determined in a
court proceeding by an appraisal process. A Real Goods shareholder who fails to
comply timely and properly with procedures of California law will not be able to
dissent from the merger and will lose their dissenters' rights.  Any Real Goods
shareholder who desires to exercise dissenters' rights should consult his or her
attorney regarding these procedures.  It is a condition to the merger that
holders of less than 5% of Real Goods common shares exercise their dissenters'
rights.

Comparative Per Share Market Price Information (see page __)

  Shares of Gaiam Class A common stock are listed on the Nasdaq National Market
under the symbol "GAIA."  Shares of Real Goods common stock are listed on the
Nasdaq Small Cap Market under the symbol "RGTC" and are also traded on the
Chicago Stock Exchange under the symbol "RGT."  On October 13, 2000, the last
full trading day before the public announcement of the proposed merger, the last
reported sale price of Gaiam Class A common stock on the Nasdaq National Market
was $17 and the last reported sale price of Real Goods common stock on the
Nasdaq Small Cap Market was $2.25.   On          , 2000, the most recent
practicable date prior to the date of this proxy statement/prospectus, the last
reported sale price


                                       5
<PAGE>

for Gaiam Class A common stock was $ and the last reported sale price for Real
Goods common stock was $     .

Listing or Quotation of Gaiam Class A Common Stock

  It is a condition to the closing of the merger that the Gaiam Class A common
stock to be issued to Real Goods shareholders in the merger be approved for
listing on the Nasdaq National Market.

Accounting Treatment  (see page __)

  Gaiam will account for the merger under the "purchase" method of accounting.
Therefore, the total merger consideration paid by Gaiam in connection with the
merger, together with the direct costs of the merger, will be allocated to Real
Goods' assets and liabilities based on their fair market values, with any excess
being treated as goodwill.  The assets and liabilities and results of operations
of Real Goods will be consolidated into the assets and liabilities and results
of operations of Gaiam after the merger.

Regulatory Matters (see page __)

  The parties do not believe any material regulatory approvals from applicable
U.S. regulatory authorities are required to permit consummation of the merger.

Interests of Directors and Executive Officers of Real Goods in the Merger  (see
pages __)

Real Goods shareholders should note that a number of Real Goods directors and
executive officers may have interests in the merger that are different from, or
in addition to, their interests as Real Goods shareholders generally.  These
interests exist because of the rights that these Real Goods executive officers
have under the terms of their benefit and compensation plans and also, in the
case of John Schaeffer, the rights he is expected to have under the terms of his
proposed employment agreement with Gaiam as described more fully under
"Interests of Insiders in the Merger".

  The members of Real Goods' board of directors knew about and considered these
additional interests when they approved the merger and the merger agreement.

Directors and Management of the Combined Company After the Merger

  Following the merger, our board of directors will consist of the 6 individuals
currently serving on Gaiam's board of directors.

  Following the merger, John Schaeffer, Real Goods' Chairman and Chief Executive
Officer, will become President of Gaiam's Real Goods division.

Conditions to the Merger (see pages __)

  We will complete the merger only if specific conditions are satisfied or, in
some cases, waived, including, among others, the following:

  .  approval by the shareholders of Real Goods;

  .  absence of any governmental proceeding or court order or law prohibiting
     (or seeking to prohibit) the completion of merger;

  .  absence of any material adverse change in the general affairs, management,
     business, operations, assets condition (financial or otherwise) or
     prospects of Real Goods or Gaiam; and

  .  holders of not more than 5% of Real Goods common stock exercising dissent
     rights.

Termination of the Merger Agreement (see pages __ )

Real Goods' and Gaiam's respective boards of directors can jointly agree to
terminate the merger agreement at any time before completing the merger. In
addition, either Real Goods or Gaiam can terminate the merger agreement if:

                                       6
<PAGE>

    .  the companies do not complete the merger by April 13, 2001 (6 months
       after the date of the merger agreement);

    .  a law or final and nonappealable court order prohibits the merger;

    .  the other party to the merger agreement breaches or fails to perform any
       of its representations, warranties, covenants or other agreements under
       the merger agreement, which would result in a closing condition not being
       satisfied, subject to a 30 day cure period; or

    .  the merger is not approved by Real Goods' shareholders.

    In addition, Gaiam can terminate the merger agreement if:

    .  any person, entity or group (other than Gaiam and its affiliates)
       increases its beneficial ownership of Real Goods common stock by an
       amount equal to 15% or more of the outstanding Real Goods common stock as
       compared with its ownership level on October 13, 2000, the date of the
       merger agreement;

    .  Real Good's board of directors withdraws or modifies in a manner adverse
       in any material respect to Gaiam its approval of the merger agreement and
       the merger or its recommendation to shareholders;

    .  Real Goods' board of directors approves or recommends an alternative
       acquisition proposal involving the acquisition of the equity securities
       or assets of Real Goods, other than the merger with Gaiam;

    .  Real Goods fails to include in the proxy statement the recommendation of
       its board of directors; or

    .  the 30-day average closing price of Gaiam Class A common stock on the
       Nasdaq National Market is greater than $22 per share, subject to certain
       notice and other conditions.

    In addition, Real Goods can terminate the merger agreement if:

    .  Real Good's board determines in good faith that an alternative
       acquisition proposal is financially superior to the merger and is
       reasonably capable of being financed, and Real Goods enters into a
       definitive agreement to effect such financially superior acquisition
       proposal; or

    .  the 30-day average closing price of Gaiam class A common stock on the
       Nasdaq National Market is less than $12 per share, subject to certain
       notice and other conditions.

Termination Fees And Expenses (see pages ____)

pay, in specified circumstances, some of the expenses of, or a termination fee
to, the other party.

Fees and Expenses To Be Paid By Gaiam

    Gaiam must pay Real Goods $1,000,000 in cash to reimburse Real Goods for its
fees and expenses incurred in connection with the merger agreement if Gaiam
terminates the merger agreement for any reason, except the reasons set forth
above in the section titled "Termination of the Merger Agreement."

Fees and Expenses To Be Paid By Real Goods

    Real Goods must pay Gaiam $1,000,000 in cash to reimburse Gaiam for its fees

<PAGE>

    .  Real Goods' board of directors withdraws or modifies, in a manner adverse
       in any material respect to Gaiam, its approval of the merger agreement
       and the merger or its recommendation to shareholders; or

    .  Real Goods' board of directors recommends or approves an acquisition
       proposal, other than the merger with Gaiam.

    .  Real Goods terminates the merger agreement because its board of directors
       determines in good faith that another acquisition proposal is financially
       superior to the merger with Gaiam and is reasonably capable of being
       financed and Real Goods enters into a definitive agreement to effect such
       financially superior acquisition proposal.

Voting Agreements (see page ___)

    In connection with the merger agreement, John Schaeffer and WholePeople.com,
who together own approximately 53.7% of the Real Goods common stock, have
entered into separate voting agreements with Gaiam pursuant to which, among
other things, they have agreed to vote all of their Real Goods common stock in
favor of the proposal to approve the merger agreement and the merger--which will
result in Real Goods obtaining the required shareholder approval for the merger.

Opinion of Financial Advisor (see pages ___)

    In connection with the merger, Real Goods' board of directors received an
opinion from Houlihan Lokey Howard & Zukin Financial Advisors, Inc. ("Houlihan
Lokey"), its financial advisor, as to the fairness of the merger to Real Goods'
shareholders from a financial point of view.  We have attached the full text of
this opinion as Annex C to this document. This opinion contains a description of
the assumptions made, matters considered and limitations on the review
undertaken in connection with this opinion. We encourage you to read and
consider the opinion addressed to the Real Goods' board of directors. The
opinion is directed to the Real Goods' board of directors and does not
constitute a recommendation to any Real Goods shareholder as to how that
shareholder should vote in connection with the merger proposals and did not
constitute a recommendation to the Real Goods' board of directors as to whether
it should approve and/or recommend the merger.

                            Selected Financial Data

    Gaiam and Real Goods have provided the following selected historical
financial data and selected pro forma combined condensed financial data to aid
you in analyzing the financial aspects of the proposed merger. The information
is only a summary and you should read it together with Gaiam's and Real Goods'
consolidated financial statements and other financial information included in
the financial statements contained elsewhere in this proxy statement/prospectus
and also, in the case of Gaiam, in the most recent annual report filed by Gaiam
with the SEC, which is incorporated by reference in this proxy
statement/prospectus. Please see the section entitled "Where You Can Find More
Information."

    The selected historical consolidated statements of operations data for the
nine-month periods ended September 30, 1999 and 2000, and for each of the fiscal
years in the three-year period ended December 31, 1999 for Gaiam, and for the
sixth -month periods ended September 25, 1999 and September 23, 2000, and for
each of the fiscal years in the three-year period ended March 31, 2000 for Real
Goods, have been derived from the consolidated statements of operations for
Gaiam and Real Goods for such periods included or incorporated by reference, as
applicable, in this proxy statement/prospectus. The consolidated statements of
operations data for the fiscal years ended December 31, 1995 and 1996 for Gaiam
and for the fiscal years ended March 31, 1996 and 1997 for Real Goods have been
derived from consolidated financial statements not included or incorporated by
reference in this proxy statement/prospectus.

    The historical consolidated balance sheet data for Gaiam as of December 31,
1998 and 1999, and September 30, 2000 and for Real Goods as of March 31, 1999
and 2000 and September 23, 2000, have been derived from financial statements for
such periods included or incorporated by reference, as applicable, in this proxy
statement/prospectus. The historical balance sheet data for Gaiam as of December
31, 1995, 1996 and 1997, and for Real Goods as of March 31, 1996, 1997 and 1998
have been derived from financial statements not included or incorporated by
reference in this proxy statement/prospectus.

    The selected unaudited pro forma combined condensed financial data reflects
the merger using the purchase method of accounting. Since the fiscal years for
Gaiam and Real Goods differ, Real Goods will change its fiscal year to coincide
with Gaiam's upon completion of the merger. The unaudited pro forma combined
condensed statements of operations combine Gaiam's consolidated statements of
operations for the nine-month periods ended September 30, 1999 and 2000 and
fiscal years ended December 31, 1999 with Real Goods' nine-month periods ended
September 25, 1999 and September 23, 2000 and fiscal year ended March 31, 2000.
The unaudited selected pro forma combined condensed balance sheet data combines
Gaiam's consolidated balance sheet data as of September 30, 2000 with Real
Goods' consolidated balance sheet data as of September 23, 2000.

    The pro forma financial information does not purport to represent what our
financial position or results of operations would actually have been had the
merger occurred at the beginning of the earliest period presented or to project
our financial position or results of operations for any future date or period.
In addition, it does not incorporate any benefits to us from cost savings or
operational synergies.

  On October 13, 2000, the last full trading day prior to the public
announcement of the proposed merger, the closing price per share of Gaiam Class
A common stock quoted on the Nasdaq National Market was $17.  On        , 2000,
the most recent practicable date prior to the date of this document, the closing
price per share of Gaiam Class A common stock reported on the Nasdaq National
Market was $ and the closing price per share of Real Goods common stock reported
on the Nasdaq Small Cap Market was $     .

  We urge Real Goods shareholders to obtain current market quotations for Gaiam
Class A common stock prior to making any decision with respect to the merger.
We cannot give any assurance to you concerning the market price for Gaiam Class
A common stock before or after the date on which the merger is consummated.  The
market price for  Gaiam Class A common stock will fluctuate between the date of
this proxy statement/prospectus and the date on which the merger is consummated
and thereafter.

                                 RISK FACTORS

  In addition to the risks of the businesses of Gaiam and Real Goods that are
described below, you should carefuly consider the following risk factors
relating to the merger in determining whether to vote in favor of the merger.
You should also consider the risk factors that will generally have an impact on
Gaiam's financial condition, results of operations and business after the
merger, including those described in the section titled"Forward Looking
Statements."

Risk Factors Relating to the Merger

The Gaiam Class A common stock to be issued in the merger will fluctuate in
value.

  In the merger, Real Goods shareholders will receive 1 share of Gaiam Class A
common stock for each 10 shares of Real Goods common stock, in addition to other
consideration.  The market price of the Gaiam Class A common stock to be issued
in the merger will fluctuate as a result of changes in the business, operations
or prospects of Gaiam or Real Goods or market assessments of the impact of the
merger.  Because the market price of Gaiam Class A common stock fluctuates, the
value of the Gaiam Class A common stock that Real Goods shareholders will
receive will depend upon the market price of those shares at the time of the
merger. We can give no assurance as to this value.

  For historical and current market prices of Gaiam shares, see "Summary--
Comparative Per Share Market Price Information." The actual performance and
volatility of Gaiam Class A common stock and/or the financial markets in general
could vary significantly more or less than that indicated by historical or
current performance and volatility.

We may experience difficulties in combining the operations of the two companies.

  The merger involves the integration of two companies that have previously
operated independently. Our future success may be dependent upon our ability to
effectively integrate these companies and their brands, including our ability to
realize potentially available marketing synergies and cost savings, some of
which may involve operational changes. We cannot be certain:

  .  as to the timing or number of marketing opportunities or amount of cost
     savings that may be realized as the result of our integration of these
     companies and their brands;

  .  that this merger will enhance our competitive position and business
     prospects; or

  .  that we will not experience difficulties with customers, personnel or other
     parties as a result of this merger.

In addition, we cannot be certain that we will be successful in:

  .  integrating Real Goods' distribution channels with those of Gaiam;

  .  selling the products of Real Goods to our customer base; or


                                      17
<PAGE>

  .  integrating Real Goods into our management information systems or in
     integrating Real Goods' products into our product mix.

  Additionally, integrating Real Goods into Gaiam's existing operations will
require management resources and may divert our management from our day-to-day
operations. If we are not successful in integrating the operations of our two
companies, the value of the Gaiam Class A common stock received in the merger
could fall.

Real Goods' officers and directors have potential conflicts of  interests in the
merger.

  In considering the recommendations of the Real Goods board of directors that
the shareholders approve the merger, you should be aware that some of the
directors and officers of Real Goods may have interests in the merger different
from or in addition to yours.  For example, John Schaeffer, one of the current
members of the board of directors of Real Goods and its Chairman, is the
controlling shareholder of Real Goods.  Following the merger, he will become
President of the Real Goods division of Gaiam and will enter into an employment
agreement with Gaiam that is expected to provide, among other things, for base
salary, bonus, grant of options, severance compensation in certain circumstances
and the right to sell a portion of the Gaiam shares he receives in the merger to
Gaiam or a third party identified by Gaiam.  See "Interests of Insiders in the
Merger--Interests of John Schaeffer."

Risk Factors Relating to the Business, Finances and Operations of the Combined
Company After the Merger.

Some of our current and future competitors may have greater financial resources
than we do or be in a better position to serve customers than we are.

  Our goal is to establish ourselves as the market leader in the LOHAS (an
acronym for Lifestyles Of Health And Sustainability) industry. We believe that
the LOHAS industry has thousands of small, local and regional businesses. Some
smaller businesses may be able to more effectively personalize their
relationships with customers.

  Some of our competitors or our potential competitors may have greater
financial and marketing resources. In addition, larger, well-established and
well-financed entities may acquire, invest in or form joint ventures with our
online competitors as the use of the Internet and other online services
increases. Increased competition from these or other competitors could
negatively impact our revenue.

   Our business is targeted at a demographic group--the cultural creatives--that
assigns high value to environmental consciousness, promoting a sustainable
economy, healthy lifestyles and personal development. The success of our
business assumes that we will be able to capture market share within this group.
Our success also depends upon the willingness of consumers to purchase goods and
services that promote the values we espouse. We cannot assure that the
demographic trends on which they are based will continue or that the current
levels of environmental consciousness or concerns about promoting a sustainable
economy, healthy lifestyles and personal development will be sustained. The
decrease of consumer interest in purchasing goods and services that promote the
values we espouse would materially and adversely affect the growth of our
customer base and sales revenues and, accordingly, our financial prospects.

                                      18
<PAGE>

The loss of the services of certain of our key personnel could disrupt our
business.

   The services of our key officers, Jirka Rysavy and Lynn Powers, are critical
to our business. Our strategy of allowing the management teams of acquired
companies to continue to exercise certain management responsibility for those
companies makes it especially important that we retain key employees,
particularly the technology and creative teams, of the companies we might
acquire.  Competition for qualified personnel is intense.

Government regulation and legal uncertainties could add additional costs to
doing business on the Internet.

   E-commerce is new and rapidly changing. Federal and state regulation relating
to the Internet and e-commerce is evolving. Currently, there are few laws or
regulations directly applicable to the Internet or e-commerce on the Internet.
Due to the increasing popularity of the Internet, it is possible that laws and
regulations may be enacted with respect to the Internet, covering issues such as
user privacy, pricing, taxation, content, copyrights, distribution, antitrust
and quality of products and services. Additionally, the rapid growth of e-
commerce may trigger the development of tougher consumer protection laws.


                                       19
<PAGE>

If the protection of our  Internet domain names is inadequate, our brand
recognition could be impaired and we could lose customers.

   We currently hold various web domain names relating to our brand, including
www.gaiam.com, and we will acquire realgoods.com in the merger.  The acquisition
and maintenance of domain names is regulated by governmental agencies and their
designees. The regulation of domain names in the U.S. and in foreign countries
is changing and is expected to continue to change in the future. As a result, we
may not be able to acquire or maintain the domain names we want in all countries
in which we seek to conduct business. Furthermore, we may be unable to prevent
third parties from acquiring domain names whose similarity decreases the value
of our trademarks and proprietary rights. Loss of our Internet domain names
could adversely affect our ability to develop brand recognition.

   Our business could also be affected by regulations adopted in the future. For
example, a number of different bills are under consideration by Congress and
various state legislatures that would restrict disclosure of consumers' personal
information. If legislation of this type were enacted, it would make it more
difficult for us to obtain additional names for our distribution lists, and
restrict our ability to send unsolicited electronic mail or printed catalogs,
both of which could slow the growth of our customer base.

The success of our business depends partially on continued growth of e-commerce.

   We are a multi-channel company and the Internet is one of our channels of
distribution.  The emergence of the Internet and the growing popularity of e-
commerce provides a new channel for direct access to consumers. Since the
introduction of e-commerce to the Internet, the number of websites competing for
customer attention has increased very rapidly. We expect future competition to
intensify given the relative ease with which new websites can be developed. We
believe that the primary competitive factors in e-commerce are brand
recognition, reputation, site content, ease of use, price, fulfillment speed,
customer support and reliability. Our success in e-commerce will depend heavily
upon our ability to continue to provide a compelling and satisfying shopping
experience. Other factors that will affect our success include our continued
ability to attract and retain experienced marketing, technology, operations and
management talent. The nature of the Internet as an electronic marketplace
(which may, among other things, facilitate competitive entry and comparison
shopping) may render it inherently more competitive than traditional retailing
formats. Increased competitiveness among online retailers may result in reduced
operating margins, loss of market share and a diminished brand franchise.

   To remain competitive, we must continue to enhance and improve the
responsiveness, functionality and features of our online technology. The
Internet and the e-commerce industry are subject to rapid technological change,
frequent new product and service introductions embodying new technologies, and
the emergence of new industry standards and practices that could render our
existing Internet strategy obsolete. Our success will depend, in part, on our
ability to license leading technologies useful in our business, enhance existing
services, develop new services and technology that address the needs of our
customers and our ability to respond to technological advances and emerging
industry standards and practices on a cost-effective and timely basis.

   The development of a website and other proprietary technology entails
significant technical, financial and business risks. We spent approximately $4.5
million in the development of our websites to date.  We intend to continue to
invest resources to enhance our websites and keep our systems up to date. In
addition, the adoption of new Internet, networking or

                                      20
<PAGE>

telecommunications technologies may require us to devote substantial resources
to modify and adapt our services.

If we cannot maintain and continuously update our information systems, our
business could suffer.

    Information systems are critical to our business. These systems assist in
processing orders, managing inventory, purchasing and shipping merchandise on a
timely basis, responding to customer service inquiries, and gathering and
analyzing operating data by business segment, customer, and SKU (a specific
identifier for each product). If our systems should require substantial updating
or fail, we could incur substantial expenses.

We may engage in future acquisitions that may harm our financial results, cause
our stock price to decline, or dilute our shareholders' interest if we do not
successfully execute them.

    Even though our strategy does not depend on making acquisitions, we expect
to make some. These acquisitions may be of entire companies, controlling
interests in companies or of minority interests in companies where we intend to
invest as part of a strategic alliance. However, we may not succeed in
identifying attractive acquisitions, and attractive acquisition candidates may
not be available at reasonable prices. We are also likely to face competition
for attractive acquisition candidates, which may increase the expense of
completing acquisitions. Making acquisitions may harm our operating results or
cause our stock price to decline because we may:

    .  issue equity or equity-related securities that dilute our current
       shareholders' percentage ownership or incur substantial debt or assume
       liabilities of an acquired business;

    .  experience reduced earnings or adverse tax consequences by failing to
       efficiently integrate the operations, assets and personnel of the
       acquired companies in a timely manner, being required to amortize a
       significant amount of intangible assets acquired in an acquisition, or
       otherwise; and

    .  divert management's attention from operating the business.

    Moreover, the presence of minority ownership interests in any acquired
company, and our strategy of allowing our subsidiaries to retain some autonomy
in their management and operation, could make integration more difficult.

A material security breach could cause us to lose sales, damage our reputation
or result in liability to us.

    Our computer servers may be vulnerable to computer viruses, physical or
electronic break-ins and similar disruptions. We may need to expend significant
additional capital and other resources to protect against a security breach or
to alleviate problems caused by any breaches. Our relationships with our
customers may be adversely affected if the security measures that we use to
protect their personal information, such as credit card numbers, are
ineffective. We currently rely on security and authentication technology that we
license from third parties. We may not be able to prevent all security breaches.

Our systems may fail or limit user traffic, which would cause us to lose sales.

                                      21
<PAGE>

    We are dependent on our ability to maintain our computer and
telecommunications equipment in effective working order and to protect against
damage from fire, natural disaster, power loss, telecommunications failure or
similar events. In addition, growth of our customer base may strain or exceed
the capacity of our computer and telecommunications systems and lead to
degradations in performance or systems failure. We have experienced capacity
constraints and failure of information systems in the past that have resulted in
decreased levels of service delivery or interruptions in service to customers
for limited periods of time. While we continually review and seek to upgrade our
technical infrastructure and provide for system redundancies and backup power to
limit the likelihood of systems overload or failure, substantial damage to our
systems or a systems failure that causes interruptions for a number of days
could adversely affect our business.

We may face legal liability for the content contained on our website or other
content that is accessed from our website.

    We intend to keep increasing the amount of content on our website. We could
face legal liability for defamation, negligence, copyright, patent or trademark
infringement, personal injury or other claims based on the nature and content of
materials that we publish or distribute on our website. These types of claims
have been brought, sometimes successfully, against on-line services in the past.
We can be exposed to litigation for the content and services that are accessible
from our website through links to other websites or through content and
materials that may be posted by our users in chat rooms or bulletin boards. If
we are held liable for damages for the content on our website, our business may
suffer. Our insurance may not adequately protect us against these types of
claims. We do not currently offer health-related information on our website, but
we may do so in the future. This could increase our legal exposure. Further, our
business is based on establishing www.gaiam.com as a trustworthy and dependable
provider of information and services. Allegations of impropriety, even if
unfounded, could therefore have a material adverse effect on our reputation and
our business.

Our suppliers may not be able to supply us merchandise in a timely manner, which
could cause us to lose sales and harm our business.

    To successfully operate our business, we must receive timely delivery of
merchandise from our vendors and suppliers. As we grow, some of these vendors
may not have sufficient capital, resources or personnel to increase their sales
to us or to satisfy their commitments to us. Any significant delay in the
delivery of products by vendors could result in a loss of sales, increased
fulfillment expenses and damage to our customer service reputation.

The failure of third parties to provide an adequate level of service could
decrease our revenues and increase our costs.

    Given our emphasis on customer service, the efficient and uninterrupted
operation of order-processing and fulfillment functions is critical to our
business. To maintain a high level of customer service, we rely heavily on a
number of different outside service providers, such as printers,
telecommunications companies and delivery companies. Any interruption in
services from outside service providers, including delays or disruptions
resulting from labor disputes, power outages, human error, adverse weather
conditions or natural disasters, could materially adversely affect our business.

Relying on our centralized fulfillment center could expose us to losing revenue.

                                      22
<PAGE>

    Prompt and efficient fulfillment of our customers' orders is critical to our
business. Our facility in Cincinnati, Ohio handles our fulfillment functions and
some customer-service related operations, such as returns processing.
Approximately 90% of our orders are filled and shipped from the Cincinnati
facility. The balance is shipped directly from suppliers. Because we rely on a
centralized fulfillment center, our fulfillment functions could be severely
impaired in the event of fire, extended adverse weather conditions, or natural
disasters. Since we charge customers' credit cards only when we ship orders,
interruption of our shipping would diminish our revenues.

Our costs could be increased by overstocks and merchandise returns, as well as
by our strategy to offer branded products.

    An important part of our strategy is to feature "branded" products. These
products are sold under our brand names and are manufactured to our
specifications. We expect our reliance on branded merchandise to increase. To be
successful, we must periodically update and expand the product offerings for our
catalogs and websites. The use of branded merchandise requires us to incur costs
and risks relating to the design and purchase of products, including submitting
orders earlier and making longer initial purchase commitments.

    In addition, the use of branded merchandise limits our ability to return
unsold products to vendors, which can result in higher markdowns in order to
sell excess inventory. Our commitment to customer service typically results in
more emphasis being placed on keeping a high level of merchandise in stock so we
can fill orders immediately. Consequently, we run the risk of having excess
inventory, which may also contribute to higher markdowns. Our failure to
successfully execute a branded merchandise strategy or to achieve anticipated
profit margins on these goods, or a higher than anticipated level of overstocks,
may materially adversely affect our revenues.

    We offer our customers liberal merchandise return policies. Our financial
statements include a reserve for anticipated merchandise returns, which is based
on historical return rates. It is possible that actual returns may increase as a
result of factors such as the introduction of new merchandise, new product
offerings, changes in merchandise mix or other factors. Any increase in our
merchandise returns will correspondingly reduce our revenues.

Our sales could be negatively affected if we are required to charge additional
taxes on purchases.

    We generally collect sales taxes only on sales to residents of the state of
Colorado and where we have other locations, currently California and Ohio.
Federal laws currently limit the imposition of state and local taxes on
Internet-related sales. However, there is a possibility that Congress may not
renew this legislation in 2001. If Congress chooses not to renew this
legislation, state and local governments would be free to impose taxes on
electronically purchased goods, which could adversely affect us. Due to the high
level of uncertainty regarding the imposition of taxes on electronic commerce, a
number of states, as well as a Congressional advisory commission, are reviewing
appropriate tax treatment for companies engaged in e-commerce. Such proposals,
if adopted, could substantially impair the growth of e-commerce and could
adversely affect our opportunity to derive financial benefit from these
activities.

    Many states have attempted to require that out-of-state direct marketers
collect sales and use taxes on the sale of merchandise shipped to its residents.
If Congress enacts legislation permitting states to impose sales or use tax
obligations on out-of-state direct marketing companies, or if other changes
require us to collect additional sales or use taxes, these obligations would
make it

                                      23
<PAGE>

more expensive to purchase our products and would increase our administrative
costs. Audits by state tax authorities could give rise to a retroactive
assessment for tax liabilities if it was determined we had sufficient activities
in that state. State sales tax laws typically provide for a lengthy statute of
limitations, and if we were retroactively assessed for taxes, the assessment
could adversely affect our business.

Our founder and chief executive officer Jirka Rysavy will control Gaiam.

Mr. Rysavy holds 100% of Gaiam's 5,400,000 outstanding shares of Class B common
stock. The shares of Class B common stock are convertible into shares of Class A
common stock at any time.   Each share of Class B common stock has ten votes per
share, and each share of Class A common stock has one vote per share, although
pursuant to a voting agreement between Gaiam and Mr. Rysavy, the Class B common
stock is limited to 49% of the total votes and all shares over this limit are
voted proportionately with the Class A common stock.  As a result of the voting
agreement, holders of Class A common stock will control the vote on all matters
to be considered by Gaiam's common stockholders.  Mr. Rysavy also owns 2,686,200
shares of Class A common stock and options to purchase 200,000 shares of Class A
common stock (of which options to purchase 36,000 shares of common stock are
exercisable within 60 days).  After giving effect to the issuance of Class A
common stock in the merger, Mr. Rysavy will beneficially own approximately
71.37% of the outstanding shares of Gaiam common stock, assuming Mr. Rysavy's
Class B common stock was converted into Class A common stock.   In addition, he
will also have approximately 75.15% of the total votes.  As a result, Mr. Rysavy
will be able to exert substantial influence over Gaiam and to control matters
requiring approval by the shareholders of Gaiam, including the election of
directors and preventing any change in control of Gaiam.

Fluctuations in our quarterly operating results may negatively affect our stock
price.

  The market price of Gaiam's Class A common stock after the merger may vary
from the current market price and could be subject to wide fluctuations in
response to factors such as the future issuance of shares as well as the
following factors that are beyond our control:

  .  quarterly variations in our operating results;

  .  operating results that vary from the expectations of securities analysts
     and investors;

  .  changes in expectations as to our future financial performance, including
     financial estimates by securities analysts and investors;

  .  announcements by third parties of significant claims or proceedings against
     us; and

  .  stock market price and volume fluctuations.


Real Goods' retail stores carry particular risks.

  There are substantial risks in store retailing, including poor location of
retail stores, failing to identify consumer trends correctly, theft by customers
and employees, inadequate merchandise selection, inadequate financial controls,
and losing customers to competitors.  Real Goods is

                                       24
<PAGE>

experimenting with retail store formats; there can be no assurance that any of
those formats will be profitable, or, if profitable, replicatable. Real Goods
has only limited experience with its new urban store format.

Real Goods may not realize a return on its investment in its Solar Living
Center.

  Real Goods' mission is "To promote and inspire an ecologically sustainable
future."  Real Goods spent approximately $3,000,000 to acquire the land for the
Solar Living Center, landscape the land and construct it as a demonstration of
many of the principles underlying Real Goods' mission and vision.  Although Real
Goods believes the response has been extremely encouraging in both sales and
number of visitors, there can be no assurance that Real Goods will ever realize
a suitable return on its investment or that Real Goods will not incur a
substantial loss from the Solar Living Center.  The Solar Living Center is
located on a flood plain; the building at the Solar Living Center is covered by
flood insurance and is above the 100 year flood mark.  Currently, a portion of
the Solar Living Center is rented to the Real Goods Institute for Solar Living,
a not-for-profit organization.

                     THE REAL GOODS SHAREHOLDERS MEETING'

General

  This proxy statement/prospectus is being furnished to the shareholders of Real
Goods in connection with the solicitation of proxies on behalf of the Real Goods
board for use at the special meeting to be held on January __, 2001, at the time
and place specified in the accompanying notice of special meeting of
shareholders, and at any adjournment or postponement thereof. The purpose of the
special meeting is to consider and vote upon proposals to:

  - approve and adopt the merger and the merger agreement; and

  - transact such other business as may properly come before the special
    meeting.

  Each copy of this proxy statement/prospectus mailed to holders of Real Goods
common stock is accompanied by a form of proxy for use at the special meeting
and is also furnished to Real Goods' shareholders as a prospectus in connection
with the issuance to them of shares of Gaiam Class A common stock in connection
with the proposed merger.

  The Board of Directors of Real Goods has approved the merger agreement and
recommends a vote FOR approval and adoption of the merger agreement.

Record Date; Quorum

  The Real Goods board of directors has fixed the close of business on
_________, 2000 as the record date for the determination of the holders of Real
Goods common stock entitled to receive notice of and to vote at the special
meeting. The presence, in person or by proxy, of the holders of a majority of
the outstanding shares of Real Goods common stock entitled to vote at the
special meeting is necessary to constitute a quorum.

Vote Required

  As of the record date for the special meeting, there were 4,814,242 shares of
Real Goods common stock outstanding, each of which is entitled to one vote on
the merger agreement and each other matter properly submitted at the special
meeting. Holders of Real Goods common stock as of the record date of the special
meeting are entitled to one vote per share of Real Goods common stock on each
matter to be considered at the special meeting.  Approval of the merger and the
merger agreement requires the affirmative vote of the holders of a majority of
the outstanding shares of Real Goods common stock entitled to vote.

  Pursuant to separate voting agreements, John Schaeffer and WholePeople.com,
who together own approximately 53.7% of Real Goods outstanding common stock,
have agreed with Gaiam to vote in favor of the merger--which will result in Real
Goods obtaining the required shareholder approval of the merger.  See "Principal
Provisions of the Merger Agreement--Voting Agreements."

Voting of Proxies


                                      26
<PAGE>

  Shares of Real Goods common stock represented by a proxy properly signed and
received at or prior to the special meeting, unless subsequently revoked, will
be voted in accordance with the instructions indicated on the proxy.

  Shares of Real Goods common stock represented at the special meeting by a
properly executed, dated and returned proxy will be treated as present at the
special meeting for purposes of determining a quorum, without regard to whether
the proxy is marked as casting a vote or abstaining. For voting purposes at the
special meeting, only shares affirmatively voted in favor of approval and
adoption of the merger agreement will be counted as favorable votes. Any broker
non-votes and abstaining votes will not be counted in favor of approval and
adoption of the merger agreement. Since applicable California law requires the
affirmative vote of a majority of the outstanding shares to approve the merger
agreement, broker non-votes and abstentions will have the same effect as votes
cast against the merger. Broker non-votes and abstentions will be counted for
purposes of establishing a quorum.

  The persons named as proxies by a shareholder may propose and vote for one or
more adjournments of the special meeting to permit further solicitations of
proxies for approval of the merger agreement; however, no proxy that is voted
against the approval of the merger agreement will be voted in favor of any such
adjournment. An adjournment proposal requires the affirmative vote of a majority
of the votes represented at the meeting.

Revocability of Proxies

  The grant of a proxy on the enclosed form does not preclude a shareholder from
voting in person. A shareholder may revoke a proxy at any time prior to its
exercise by submitting a signed written revocation to the secretary of Real
Goods, by submitting a signed proxy bearing a later date or by appearing at the
special meeting and voting in person at the special meeting. No special form of
revocation is required. Attendance at the special meeting will not, in and of
itself, constitute revocation of a proxy.

Solicitation of Proxies

  Real Goods will bear the cost of the solicitation of proxies from its
shareholders, including the costs of preparing, filing, printing and
distributing this proxy statement/prospectus and any other solicitation
materials that are used.

  Directors, officers and employees will not be additionally compensated but may
be reimbursed for reasonable out-of-pocket expenses in connection with any proxy
solicitation.  Arrangements will also be made with brokerage houses and other
custodians, nominees and fiduciaries for the forwarding of solicitation material
to the beneficial owners of stock held of record by those persons, and Real
Goods will reimburse all custodians, nominees and fiduciaries for their
reasonable out-of-pocket expenses in connection with these actions.

  The matters to be considered at the special meeting are of great importance to
Real Goods' shareholders. Accordingly, Real Goods' shareholders are urged to
read and carefully consider the information presented in this proxy
statement/prospectus, and to complete, date, sign and promptly return the
enclosed proxy in the enclosed postage pre-paid envelope.

  Shareholders should not send Real Goods common stock certificates with their
proxy cards. If the merger agreement is approved by the shareholders and the
merger is

                                      27
<PAGE>

consummated, transmittal forms and instructions will be sent to Real Good
shareholders for the exchange of shares of Real Goods common stock for Gaiam
Class A common stock and the other merger consideration.

                                  THE MERGER

General

  We are furnishing this proxy statement/prospectus to holders of Real Goods
common stock in connection with the solicitation of proxies by Real Goods' board
of directors at a special meeting of its shareholders, and at any adjournments
or postponements of the shareholders' meeting.

Real Goods' Proposals

  At the Real Goods special shareholders' meeting, Real Goods will ask its
shareholders to vote on the following proposals:

  - to approve and adopt the merger agreement and the merger; and

  - to transact such other business as shall properly come before the special
    meeting.

  The merger agreement provides for the merger of a wholly-owned subsidiary of
Gaiam with and into Real Goods, with Real Goods surviving the merger and
becoming a wholly-owned subsidiary of Gaiam.  In exchange for each 10 shares of
Real Goods common stock, each shareholder of Real Goods will receive 1 share of
Gaiam Class A common stock and, if such shareholder elects, gift certificates to
purchase Gaiam's or Real Goods' products, in an amount equal to $1 for each
share of Real Goods common stock exchanged in the merger, up to a maximum of
$100 for such shareholder.  In lieu of any fractional share of Gaiam Class A
common stock that would otherwise be issuable to a holder of Real Goods common
stock, Gaiam will issue $1 in additional Gaiam gift certificates for each $1
(rounded up to the nearest whole dollar) in market value of fractional Gaiam
Class A shares to which such holder would otherwise have been entitled had
fractional shares been issued.

  The merger will become effective in accordance with the certificate of merger
to be filed with the office of the Secretary of State of California. We
anticipate that the parties will make this filing as soon as practicable after
the last of the conditions precedent to the merger contained in the merger
agreement has been satisfied or waived. We have attached a copy of the merger
agreement as Annex A to this document. We urge all shareholders of Real Goods to
read the merger agreement in its entirety because it is the legal document
governing the merger.

Background of the Merger

  The respective board of directors and management of Gaiam and Real Goods
regularly consider their strategic alternatives as part of their ongoing efforts
to enhance shareholder value. These alternatives have included entering into
strategic relationships and making strategic acquisitions to gain access to
greater financial resources and marketing capabilities.

  Gaiam is a multi-channel lifestyle company marketing to customers who value
the environment, personal development and a healthy lifestyle.  Real Goods sells
a broad range of renewable energy and sustainable living products through its
mail order catalogs and four retail stores and on its website.  Gaiam's
Chairman, Jirka Rysavy, and Real Goods' Chairman, John Schaeffer, have known
each other for a number of years and have had discussions from time to time
about how their companies might work together or perhaps combine their
operations.

                                      29
<PAGE>

     In June of 2000, Gaiam.com, Inc., Gaiam's Internet subsidiary, acquired the
Internet operations of Whole Foods Markets, Inc., operating as Wholepeople.com.
In connection with the transaction, Gaiam.com acquired an option to purchase
Wholepeople.com's 800,000 Real Goods shares for cancellation of $2,000,000 in
indebtedness owed by Wholepeople.com to Gaiam.com.

     Following announcement of the Whole Foods transaction, in late June Mr.
Schaeffer contacted Mr. Rysavy to discuss Gaiam's interest in a possible
transaction between Gaiam and Real Goods. Discussions continued during July and
August. On August 24, Gaiam's management made a preliminary presentation to
Gaiam's board concerning a possible transaction with Real Goods. Gaiam's board
authorized management to continue discussions with Real Goods and indicated
preliminarily that the board would approve a transaction with Real Goods,
subject to due diligence and negotiation of a definitive agreement, provided
that the price did not exceed an exchange ratio of 0.1170 Gaiam share for each
Real Goods share, which, at prevailing market prices for Gaiam stock at the
time, would have valued Real Goods' shares at approximately $2 per share.

     In early September the parties executed a formal confidentiality agreement
so that detailed due diligence could be conducted. On September 11 and 12, the
parties met to commence due diligence and discuss the potential transaction.
During the next month, the parties conducted due diligence with respect to the
other party's financial statements, corporate organization, background, and
other matters.

     In early September, Gaiam's legal advisors and Real Goods' legal advisors
commenced documentation of the proposed transaction.  Negotiations concerning
the merger agreement and related documentation continued during September and
early October and involved Messrs. Rysavy and Schaeffer and Gaiam's and Real
Goods' respective legal advisors.

     During September, Mr. Schaeffer interviewed several investment banking and
valuation firms and subsequently recommended to the Real Goods board that the
company retain Houlihan Lokey as its financial advisor in connection with the
proposed merger.   On September 26, 2000, Real Goods entered into a letter
agreement with Houlihan Lokey for such purpose.

     On October 6, 2000, the Real Goods' board met to consider the proposed
merger with Gaiam.  The Real Goods board considered a range of strategic
alternatives for the company in addition to the merger, including liquidating
the company, continuing to operate the company and entering into a strategic
relationship with another party.  At the meeting, Houlihan Lokey delivered its
oral opinion, which was subsequently confirmed in writing, that, as of the date
of its opinion and subject to the assumptions, qualifications and limitations
set forth in its written opinion, the proposed exchange ratio was fair, from a
financial point of view, to Real Goods shareholders.  The Real Goods board
unanimously approved the proposed merger agreement.

     Gaiam's board met on October 10, 2000 to consider the merger and the
proposed merger agreement and the results of Gaiam's due diligence, including
Real Goods' second quarter financial results, which were worse than expected. As
a result, Gaiam's board determined that it would not offer the discussed ratio
of 0.1170 and instead instructed Mr. Rysavy to review with Mr. Schaeffer and
Real Goods whether Real Goods' board would accept an exchange ratio of 0.1 Gaiam
shares for each Real Goods share. Based on prevailing market prices for Gaiam
Class A common stock at the time, the revised exchange ratio would have valued
shares of Real Goods common stock at approximately $1.75 per share. Gaiam's
board of directors approved the proposed merger and the merger agreement subject
to the exchange ratio being revised to 0.1 Gaiam shares for each Real Goods
share.

     On October 11, 2000, Real Goods' board of directors met to consider the
merger and the revised exchange ratio.  At the meeting, Houlihan Lokey delivered
it oral opinion, which was subsequently confirmed by delivery of a written
opinion dated October 11, 2000 that, as of the date of the written opinion and
subject to the assumptions, qualifications and limitations set forth in the
written opinion, the revised exchange ratio of one Gaiam share for each ten Real
Goods shares was fair, from a financial point of view, to Real Goods
shareholders.  The Real Goods board approved the revised exchange ratio and the
proposed merger agreement.


                                      30
<PAGE>

     Following approval of the merger agreement reflecting the revised exchange
ratio and the proposed merger by each of Gaiam's and Real Goods' board of
directors, Gaiam and Real Goods concluded the final negotiations concerning the
merger agreement and executed the final merger agreement late in the day on
October 13, 2000.

Considerations of Real Goods' Board of Directors

  At its meetings on October 6 and 11, 2000, Real Goods' board voted unanimously
to enter into the merger agreement and to recommend that Real Goods shareholders
vote to approve the merger and the merger agreement.

  In the course of reaching its decision to adopt the merger agreement, Real
Goods' board consulted with Real Goods' management, as well as its outside legal
counsel and financial advisor, and carefully considered the following material
factors:

     .  information concerning the business, earnings, operations and prospects
        of Real Goods individually and on a combined basis with Gaiam, including
        but not limited to the compatibility of the two companies' products and
        significant operating synergies and economies of scale expected to be
        realized as a result of merger;

     .  the presentations of Houlihan Lokey at Real Goods' board meetings on
        October 6 and 11, 2000 and the opinion of Houlihan Lokey dated October
        11, 2000 that, as of the date of Houlihan Lokey's opinion, the exchange
        ratio to be received for the merger was fair to Real Goods' stockholders
        from a financial point of view. The full text of Houlihan Lokey's
        opinion, which sets forth assumptions made, matters considered and
        limitations on the review undertaken in connection with Houlihan Lokey's
        opinion, is attached hereto as Annex C and is incorporated by reference
        in this proxy statement/prospectus. We urge Real Goods' shareholders to
        read Houlihan Lokey's opinion in its entirety;

     .  the amount and form of the consideration to be received by Real Goods'
        shareholders in the merger and information on the historical trading
        ranges of Real Goods common stock and Gaiam Class A common stock;

     .  that the board believed that the merger consideration to be received by
        Real Goods' shareholders was the maximum value Real Goods' shareholders
        could obtain for their shares and the maximum value Gaiam was prepared
        to pay for acquiring Real Goods;

     .  that the board believed the merger would enable Real Goods shareholders
        to participate in the future growth potential of the combined company
        and share in any cost reduction and revenue enhancements which may be
        realized as a result of the merger;

     .  that the transaction would provide Real Goods shareholders with a wider
        shareholder base, float and greater liquidity.

     .  that the Real Goods board believed that, because of the similarity of
        mission and culture of the two companies, the merger would enable Real
        Goods to take

                                      31
<PAGE>

        advantage of the larger resources of the combined company and more
        quickly advance its mission to promote and inspire an ecologically
        sustainable future than it could on its own;

     .  that the Real Goods board believed that Real Goods would be able to take
        advantage of Gaiam's experienced management team, thereby reducing its
        need to retain and attract employees in the highly competitive Northern
        California market; and

     .  the interest that certain executive officers of Real Goods may have in
        connection with the merger that may be different from, or in addition
        to, their interests as shareholders of Real Goods generally, see
        "Interests of Insiders in the Merger."

In view of the number and wide variety of factors considered in connection with
its evaluation of the merger, and the complexity of these matters, Real Goods'
board did not find it practicable to, nor did it attempt to, quantify, rank or
otherwise assign relative weights to the specific factors it considered. In
addition, the Real Goods board did not undertake to make any specific
determination as to whether any particular factor was favorable or unfavorable
to the board of directors' ultimate determination or assign any particular
weight to any factor, but rather conducted an overall analysis of the factors
described above, including through discussions with and questioning of Real
Goods' management and management's analysis of the proposed merger based on
information received from Real Goods' legal, financial and accounting advisors.
In considering the factors described above, individual members of the Real Goods
board may have given different weight to different factors. Real Goods' board
considered all these factors as a whole, and overall considered the factors to
be favorable to and to support its determination.

Recommendation of Real Goods' Board of Directors

  Real Goods' Board of Directors believes that the terms of the merger are fair
to and in the best interests of Real Goods and its shareholders and unanimously
recommends to its shareholders that they vote "For" the proposal to approve and
adopt the merger and the merger agreement.

Accounting Treatment

  Gaiam will account for the merger under the "purchase" method of accounting
in accordance with generally accepted accounting principles. Therefore, the
total merger consideration paid by Gaiam in connection with the merger, together
with the direct costs of the merger, will be allocated to Real Goods' assets and
liabilities based on their fair market values, with any excess being treated as
goodwill. The assets and liabilities and results of operations of Real Goods
will be consolidated into the assets and liabilities and results of operations
of Gaiam after the merger.

Material Federal Income Tax Consequences of the Merger

  The following discussion summarizes the material United States federal income
tax consequences of the merger. This discussion is based on the Internal Revenue
Code of 1986, as amended, applicable Treasury regulations, administrative
interpretations and court decisions as in effect as of the date of this proxy
statement/prospectus, all of which may change, possibly with retroactive effect.


                                       32
<PAGE>

  This discussion does not address all aspects of United States federal income
taxation that may be important to a Real Goods shareholder in light of that
shareholder's particular circumstances or to a Real Goods shareholder subject to
special rules, such as:

  - a nonresident alien individual, foreign corporation or foreign estate or
    trust;

  - a shareholder who does not hold its Real Goods common stock as a capital
    asset;

  - a financial institution or insurance company;

  - a tax-exempt organization;

  - a dealer or broker in securities;

  - a partnership or other pass-through entity, or an investor in a partnership
    or other pass-through entity;

  - a shareholder that holds its Real Goods common stock as part of a hedge,
    appreciated financial position, straddle or conversion transaction; or

  - a shareholder who acquired its Real Goods common stock pursuant to the
    exercise of options or otherwise as compensation.

    The following discussion is not binding on the Internal Revenue Service or
any court and no ruling has been, or will be, sought from the Internal Revenue
Service as to the United States federal income tax consequences of the merger.

    Gaiam and Real Goods intend to take the position that the merger will
qualify as a reorganization within the meaning of Section 368(a) of the Code.
Assuming the merger qualifies as a reorganization within the meaning of Section
368(a) of the Code, a holder of Real Goods stock who exchanges his or her Real
Goods stock solely for Gaiam common stock in the merger will not recognize gain
or loss for United States federal income tax purposes.  Each holder's aggregate
tax basis in the Gaiam common stock received in the merger will generally be the
same as his or her aggregate tax basis in the Real Goods stock surrendered in
the merger.

    Each holder of Real Goods common stock that receives Gaiam Class A common
stock in the merger will be required to retain records and file with such
holder's United States Federal income tax return a statement setting forth
specific facts relating to the merger.

Federal Income Tax Treatment of the Merger.  The merger will be treated for
federal income tax purposes as a reorganization within the meaning of Section
368(a) of the Internal Revenue Code, and Gaiam, its merger subsidiary and Real
Goods will each be a party to that reorganization within the meaning of Section
368(b) of the Internal Revenue Code. None of Gaiam, its merger subsidiary or
Real Goods will recognize any gain or loss for federal income tax purposes as a
result of the merger.

Federal Income Tax Consequences to Real Goods Shareholders.   For federal income
tax purposes:


                                      33
<PAGE>

  -   A holder of Gaiam Class A common stock will not recognize any gain or loss
upon exchange in the merger of its shares of Real Goods common stock for shares
of Gaiam Class A common stock;

  -   A holder of Real Goods common stock that receives gift certificates
instead of a fractional share of Gaiam's Class A common stock will be required
to recognize gain or loss, measured by the difference between the fair market
value of gift certificates received instead of that fractional share and the
portion of the tax basis of that holder's shares of Real Goods common stock
allocable to that fractional share. This gain or loss will be capital gain or
loss, and will be long-term capital gain or loss if the share of Real Goods
common stock exchanged for that fractional share of Gaiam Class A common stock
was held for more than one year at the effective time of the merger;

  -   A holder of Real Goods common stock that elects to receives a $1 gift
certificate for each Real Goods common share exchanged in the merger, up to a
maximum of $100 in gift certificates per shareholder, will be required to
recognize gain equal to the value of the gift certificates, but limited to the
amount by which the fair market value of the Gaiam shares they receive in the
merger exceeds their tax basis in the Real Goods shares exchanged for the Gaiam
shares.  Any such gain will be capital gain, and will be long-term capital gain
if the shares of Real Goods common stock exchanged for shares of Gaiam Class A
common stock in the merger were held for more than one year at the effective
time of the merger;


  -   A holder of Real Goods common stock will have a tax basis in the Gaiam
Class A common stock received in the merger equal to (1) the tax basis of the
Real Goods common stock surrendered by that holder in the merger, less (2) any
tax basis of the Real Goods common stock surrendered that is allocable to any
fractional share of Gaiam Class A common stock for which a Gaiam gift
certificate is received; plus (3) the amount of gain recognized upon the receipt
of the $1gift certificate for each Real Goods common share exchanged in the
merger, up to a maximum of $100 in gift certificates per shareholder, less (4)
the fair market value of the $1 gift certificate for each Real Goods common
share exchanged in the merger, up to a maximum of $100 in gift certificates per
shareholder;

  -   The holding period for shares of Gaiam Class A common stock received in
exchange for shares of Real Goods common stock in the merger will include the
holding period for the shares of Real Goods common stock surrendered in the
merger; and

  -   Certain non-corporate holders of Real Goods common stock may be subject to
backup withholding at a 31% rate on payments made with respect to the merger if
the holder fails to provide an accurate taxpayer identification number and other
information or is otherwise subject to backup withholding. The amount of any
backup withholding from a payment to a holder will be allowed as a credit
against the holder's U.S. federal income tax liability.

Federal Income Tax Consequences to Gaiam Shareholders. For federal income tax
purposes, holders of Gaiam Class A common stock will not recognize gain or loss
as a result of the merger.

      This discussion of material federal income tax consequences is intended to
provide only a general summary, and is not a complete analysis or description of
all potential federal income tax consequences of the merger. This discussion
does not address tax consequences that may vary with, or are contingent on,
individual circumstances. In addition, it does not address any non-income tax or
any foreign, state or local tax consequences of the merger. Accordingly, we


                                      34
<PAGE>

strongly encourage each Real Goods shareholder to consult his or her own tax
advisor to determine the particular United States federal, state, local or
foreign income or other tax consequences to the shareholder of the merger.

Regulatory Matters

     We will obtain all material regulatory approvals required to permit
completion of the merger from the applicable U.S. regulatory authorities.

Appraisal or Dissenters' Rights

     If the merger is completed, Real Goods shareholders entitled to vote on the
merger will be entitled to dissenters' rights in limited circumstances. Chapter
13 of the California corporate law provides that a Real Goods shareholder who
does not vote in favor of the merger and who also complies with certain
procedures and requirements may dissent from the merger and elect to receive
cash in lieu of Gaiam Class A common stock.  The amount of cash will be the
"fair market value" of the shareholder's Real Goods stock (exclusive of any
appreciation or depreciation in connection with the proposed merger), determined
as of the day before the first announcement of the terms of the proposed merger.

     The following is a summary of the provisions of Chapter 13 of the
California corporate law, which governs dissenters' rights.  This summary is
qualified in its entirety by reference to the full text of Chapter 13, which is
included as Annex B.   Failure to strictly follow the procedures set forth in
Chapter 13 may result in the loss, termination or waiver of dissenters' rights.
The procedure to perfect dissenters' rights is complex and a Real Goods
shareholder considering exercising dissenters' rights should contact his or her
attorney.

     Within 10 days after the date of the approval of the merger by Real Goods'
shareholders, Real Goods will mail to each Real Goods shareholder who did not
vote in favor of the merger a notice of approval of the merger, together with a
copy of Sections 1300, 1301, 1302, 1303 and 1304 of the California corporate
law, a statement of the price determined by Real Goods to represent the fair
market value of dissenting shares, and a brief description of the procedure to
be followed if the shareholder desires to exercise dissenters' rights under
California law. The statement of the fair market value of the Real Goods common
stock in the notice will constitute an offer by Real Goods to purchase at that
price any shares of Real Goods stock for which dissenters' rights are perfected.

     The procedure to perfect dissenters' rights is complex. Failure to strictly
follow the procedures set forth in Chapter 13 of the California corporate law
may result in the loss, termination or waiver of dissenters' rights. A Real
Goods shareholder considering exercising dissenters' rights should contact his
or her attorney.  A shareholder of Real Goods wishing to exercise dissenters
rights must take the following actions:

  -The shareholder must not have voted in favor of approval of the merger. A
   Real Goods shareholder who votes to approve the merger will not have a right
   to dissent from the merger;

  -The shareholder must make written demand upon Real Goods to have Real Goods
   purchase those shares for cash at their fair market value. The demand must
   be made by a person who was a shareholder of record on the date for the
   determination of shareholders entitled to vote


                                      35
<PAGE>

   on the merger, must state the number and class of dissenting shares held of
   record by the dissenting shareholder and must contain a statement of what the
   shareholder claims to be the fair market value of the shares as of the last
   day before the merger was first announced. The statement of fair market value
   by the shareholder will constitute an offer by the shareholder to sell the
   shares to Real Goods at the specified price. The written demand must be
   received by Real Goods within 30 days after the date on which the notice of
   the approval of the merger by Real Goods' shareholders is mailed to the
   shareholder. If the shareholder's demand is not received by Real Goods within
   this 30-day period, then the shareholder will forfeit his or her dissenter's
   rights; and

  -The shareholder must also submit to Real Goods, within 30 days after the date
   on which the notice of approval of the merger by Real Goods shareholders is
   mailed to the shareholder, at Real Goods principal office or the office of
   its transfer agent, the certificates representing any shares of Real Goods
   common stock with respect to which demand for purchase is being made, to be
   stamped or endorsed with a statement that the shares are dissenting shares.

     Under California law, a dissenting shareholder may not withdraw his or her
demand for payment of the fair market value of the shareholder's dissenting
shares in cash unless Real Goods consents.

     If the shareholder and Real Goods agree that the shares of Real Goods
common stock as to which the shareholder is seeking dissenters' rights are
dissenting shares, and also agree upon the price to be paid to purchase the
shares, then the dissenting shareholder is entitled to the agreed price with
interest at the legal rate on judgments under California law from the date of
the agreement.

     However, if Real Goods denies that the shareholder's shares qualify as
dissenting shares eligible for purchase under Chapter 13 of the California
corporate law, or Real Goods and the shareholder fail to agree upon the fair
market value of the shares, then the shareholder may, within six months after
the date on which Real Goods mailed to the shareholder the notice of approval of
the merger by Real Goods shareholders, but not thereafter, file a complaint in
the California Superior Court requesting the Court to determine whether the
shareholder's shares qualify as dissenting shares that are eligible to be
repurchased pursuant to the exercise of dissenters' rights, the fair market
value of such shares, or both, or may intervene in any action pending on such a
complaint.

     If the Court is requested to determine the fair market value of the shares,
it appoints one or more impartial appraisers to determine the fair market value
of the shares. However, if the appraisers cannot determine the fair market value
within ten days of their appointment or within a longer time determined by the
Court, then the Court will determine the fair market value. If the Court
determines that the shareholder's shares qualify as dissenting shares, then
following determination of their fair market value Real Goods will be obligated
to pay the dissenting shareholder the fair market value of the shares, as so
determined, together with interest thereon


                                      36
<PAGE>

at the legal rate from the date on which judgment is entered. Payment on this
judgment will be due upon the endorsement and delivery to Real Goods of the
certificates for the shares as to which the dissenters' rights are being
exercised.

     The costs of the appraisal action, including reasonable compensation to the
appraisers appointed by the court, will be allocated among Real Goods and
dissenting shareholders as the Court deems equitable. However, if the appraisal
of the fair market value of the shares exceeds the price offered by Real Goods,
then Real Goods shall pay such costs. If the fair market value of the shares
awarded by the Court exceeds 125% of the price offered by Real Goods for the
shares in the notice of approval of the merger by Real Goods' shareholders, then
the Court may in its discretion include attorneys' fees, fees of expert
witnesses and interest in the costs payable by Real Goods.

     Under California corporate law, a written demand for appraisal must
reasonably inform Real Goods of the identity of the shareholder of record making
the demand and that the shareholder intends to demand appraisal of the
shareholder's shares. A demand for appraisal should be executed by or for the
Real Goods shareholder of record, fully and correctly, as that shareholder's
name appears on the shareholder's stock certificate. If Real Goods common stock
is owned of record in a fiduciary capacity, such as by a trustee, guardian or
custodian, the demand should be executed by the fiduciary. If Real Goods common
stock is owned of record by more than one person, as in a joint tenancy or
tenancy in common, the demand should be executed by or for all joint owners. An
authorized agent, including an agent for two or more joint owners, should
execute the demand for appraisal for a shareholder of record; however, the agent
must identify the record owner and expressly disclose the fact that, in
exercising the demand, he, she or it is acting as agent for the record owner.

     If you are a holder of Real Goods common stock and you are considering
exercising your dissenters' rights, you should be aware that the fair market
value of your Real Goods common stock as determined under Chapter 13 of the
California corporate law could be greater than, the same as, or less than the
value of the Gaiam Class A common stock that you would otherwise receive in the
merger.

     If you desire to exercise dissenters' rights you should consult your
attorney regarding the required procedures.

Federal Securities Law Consequences

  This proxy statement/prospectus does not cover any resales of the Gaiam Class
A common stock to be received by Real Goods' shareholders upon completion of the
merger, and no person is authorized to make any use of this document in
connection with any such resale.

  All Gaiam Class A common stock that Real Goods shareholders receive in the
merger will be freely transferable, with the exception of the Gaiam Class A
common stock received by persons who are deemed to be "affiliates" of Real Goods
under the Securities Act, at the time of the Real Goods shareholders' meeting.
These "affiliates" may only sell their Gaiam Class A common stock in
transactions permitted by Rule 145 under the Securities Act or as otherwise
permitted under the Securities Act. Persons who may be deemed to be affiliates
of Real Goods for such purposes generally include individuals or entities that
control, are controlled by, or are under common control with, Real Goods and may
include some officers, directors and principal shareholders of Real Goods. The
merger agreement requires Real Goods to use commercially reasonable efforts to
deliver or cause to be delivered to Gaiam on or prior to the effective time of
the merger from


                                      37
<PAGE>

each of those affiliates an executed letter agreement to the effect that those
persons will not offer or sell or otherwise dispose of any Gaiam Class A common
stock issued to them in the merger in violation of the Securities Act.

                  PRINCIPAL PROVISIONS OF THE MERGER AGREEMENT

  The following is  a summary of the merger agreement, a copy of which is
attached as Annex A and is incorporated into this proxy statement/prospectus by
reference.  Shareholders of Real Goods are urged to read the merger agreement in
its entirety for a more complete description of the terms and conditions of the
merger.

General

  The merger agreement provides for the merger of a wholly-owned subsidiary of
Gaiam into Real Goods.  Real Goods will survive the merger and continue to exist
after the merger. The merger will become effective at the time a certificate of
merger is filed with the Secretary of State of California, or a later time if
agreed in writing by the parties and specified in the certificate of merger. The
merger is expected to occur as soon as practicable after all conditions to the
merger have been satisfied or waived. The merger agreement obligates Gaiam to
have the Gaiam common stock to be issued in connection with the merger approved
for listing on the Nasdaq National Market, subject to official notice of
issuance, prior to the effective time of the merger.

Consideration to be Received in the Merger

  At the effective time of the merger, Real Goods' shareholders will receive 1
share of Gaiam Class A common stock in exchange for every 10 shares of Real
Goods common stock they own.  Each share of Real Goods common stock owned by
Real Goods will be canceled and retired. In addition to the shares of Gaiam
Class A common stock, Gaiam will provide each Real Goods shareholder a gift
certificate to purchase Gaiam's or Real Goods' products, in an amount equal to
$1 for each share of Real Goods common stock exchanged in the merger, up to a
maximum of $100 for such shareholder.  In lieu of any fractional share of Gaiam
Class A common stock, Gaiam will issue $1 in additional gift certificates for
each $1 (rounded up to the nearest whole dollar) in market value of fractional
Gaiam Class A shares to which such holder would otherwise have been entitled had
fractional shares been issued.

Conversion of Shares

  Gaiam will appoint an exchange agent who will pay the merger consideration in
exchange for certificates representing shares of Real Goods' common stock.
Promptly after the merger, the exchange agent will send record holders of Real
Goods common stock a letter of transmittal and instructions explaining how to
send stock certificates to the exchange agent as well as  a form to be completed
by those record holders electing to receive gift certificates in the merger.
The exchange agent will receive all certificates for shares that are exchanged
for the merger consideration.  If you send your stock certificates to the
exchange agent, together with a properly completed letter of transmittal, then
promptly after the exchange agent receives and processes your documents, the
merger consideration will be mailed to you, subject to any tax withholding
required by law.

  Persons holding Real Goods shares in street name will not receive or need
to return a letter of transmittal, and Gaiam shares will be substituted
automatically for Real Goods shares in their accounts.  However, Gaiam  will
send a letter to such street holders in connection with the distribution of gift
certificates to such holders.  The letter will contain a form that must be
completed by the shareholder and returned to Gaiam in order receive gift
certificates.  The form will require such holder's name, address and
documentation (such as a brokerage account statement) showing his or her Real
Goods holdings as of the effective date of the merger.


                                       39

Covenants

  Interim Operations of Real Goods. Until the merger, Real Goods and its
subsidiaries are required to comply with covenants concerning the operation of
their businesses, compliance with applicable laws, corporate structure,
governance and financing, and compensation of management. In general, Real Goods
must operate during this period in all material respects in the usual and
ordinary course, consistent with past practices.  Real Goods must also obtain
Gaiam's consent for some actions such as significant acquisitions or incurring
indebtedness other than in the ordinary course of business, and afford Gaiam
access to Real Goods' properties and records.

  Other Covenants. The merger agreement contains mutual covenants of Gaiam and
Real Goods applicable to consummating the merger and all related transactions.
These include covenants relating to public announcements, notification if some
matters occur, and cooperation in connection with governmental filings and in
obtaining consents.

  Special Meeting; Proxy Material.  Gaiam and Real Goods agreed to prepare this
proxy statement/prospectus, and Real Goods agreed to mail this proxy
statement/prospectus to each holder of Real Goods' common stock and call and
hold the special meeting. Real Goods also agreed to use all commercially
reasonable efforts to obtain shareholder adoption of the merger agreement.

  No Solicitation by Real Goods.  Subject to exceptions summarized below, Real
Goods agreed that it will not directly or indirectly, solicit, initiate or
encourage any Acquisition Proposal or negotiate with respect to any Acquisition
Proposal.  Real Goods also agreed it will not respond to inquiries or assist or
cooperate with any person to make any Acquisition Proposal or disclose the
existence of discussions between Gaiam and Real Goods. An "Acquisition Proposal"
is any proposal or offer with respect to:

  - a tender or exchange offer, a merger, consolidation or other business
    combination involving Real Goods or any of its subsidiaries, including a
    merger of equals involving Real Goods,

  - the acquisition of an equity interest in Real Goods representing in excess
    of  33% of the power to vote for the election of a majority of directors of
    Real Goods, or

  - the acquisition of assets of Real Goods or its subsidiaries, including stock
    of one or more subsidiaries of Real Goods, representing 33% or more of the
    consolidated assets of Real Goods, in each case by any person other than
    Gaiam or its affiliates.

  Real Goods has agreed to cease any solicitation of any Acquisition Proposal.
As indicated above, Real Goods ceased such activities prior to the signing of
the merger agreement, when the board of directors of Real Goods concluded its
process of review. At that time, the Real Goods' board of directors had not
received offers for or indications of interest with respect to Real Goods from
any parties other than Gaiam, and the board was not in the process of discussing
or negotiating any such offers or indications of interest.

  However, the merger agreement provides that the Real Goods board may authorize
Real Goods to engage in discussions or negotiations concerning an unsolicited
Acquisition Proposal, and may furnish information and cooperate in this regard.


                                       40
<PAGE>

  In addition, the merger agreement provides that, following receipt of an
Acquisition Proposal, Real Goods must inform Gaiam of the receipt of the
Acquisition Proposal and the material terms and conditions unless it would be a
breach of the Real Goods board's fiduciary duties to do so.  In addition, Real
Goods may not enter into a definitive agreement in connection with the
Acquisition Proposal less than 3 business days after its notice to Gaiam unless
it would be a breach of the Real Goods board's fiduciary duties to do so.
Within that 3 business day period, Gaiam may propose an improved transaction.

  Real Goods has agreed not to engage in negotiations with, or disclose any
nonpublic information to, any person unless it receives from the person an
executed confidentiality agreement.

  Antitakeover Statutes. Real Goods and its board of directors agreed to act to
eliminate or minimize the effects of any takeover statute on the merger and all
related transactions.

agreement;

        - any representation or warranty of Real Goods under the merger

                                      43
<PAGE>

    definitive agreement to effect the financially superior Acquisition
    Proposal, and Real Goods has complied with the covenant regarding
    Acquisition Proposals set forth above under "--Covenants";

  - any representation or warranty of Gaiam under the merger agreement is untrue

of being financed and Real Goods enters into a definitive agreement to effect
the Acquisition Proposal.

  The termination provisions relating to Real Goods' failure to call a meeting
of its shareholders within a reasonable time, or failure as promptly as
reasonably practicable to mail a registration statement or proxy statement to
its shareholders, or failure to include in the proxy statement the board's
recommendation, are no longer relevant.

Expenses

                                      44
<PAGE>

  All costs and expenses incurred in connection with the merger agreement and
the transactions contemplated by the merger agreement, other than termination
fees payable upon termination under "--Termination Fees Payable by Gaiam" and

limitation, the preparation, execution and performance of the merger agreement
and the transactions contemplated by such agreement and all fees and expenses of
any investment banker, finders, broker, agent, representative, counsel or
accountant.

Voting Agreements

  On October 13, 2000, John Schaeffer and Wholepeople.com, in their capacity as
shareholders of Real Goods, entered into separate voting agreements with Gaiam,
pursuant to which they each agreed to vote their Real Goods shares in favor of
the merger agreement and the merger at the special meeting of Real Goods
shareholders.

Amendments; Waivers

  The provisions of the merger agreement may be amended or waived if, and only
if, the amendment or waiver is in writing and signed, in the case of an
amendment, by Gaiam and Real Goods, and, in the case of a waiver, by the party
against whom the waiver is to be effective.  However, after the merger agreement
has been adopted by Real Goods' shareholders, the any amendments or waivers that
change the merger consideration, any term of the articles of incorporation of
Gaiam Subsidiary, Inc., the surviving corporation, or any of the terms or
conditions of the merger agreement if such change would adversely affect the
Real Goods' shareholders.

Consequences of the Merger

  After the merger, Real Goods' shareholders will no longer have any direct
interest in Real Goods or its future earnings.  The shares of Real Goods common
stock will be deregistered under the federal securities laws and will no longer
be quoted on the Nasdaq Small Cap Market or any exchange.

          UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS

  On October 13, 2000, Gaiam and Real Goods entered into an agreement and plan
of merger. Under the agreement, Gaiam is to issue 1 share of Gaiam common stock
for every 10 shares of common stock of Real Goods.  The merger is subject to,
among other things, regulatory approval and the approval by shareholders of Real
Goods. The transaction, which is intended to be accounted for as a purchase
transaction, is expected to be consummated on January    , 2001.

  The following unaudited pro forma combined condensed financial information
gives effect to the merger using the purchase method of accounting, after giving
effect to the pro forma adjustments described in the accompanying notes. The
unaudited pro forma combined condensed financial information should be read in
conjunction with the audited historical consolidated financial statements and
related notes thereto of Gaiam and Real Goods.

  The unaudited pro forma combined condensed balance sheet data as of September
30, 2000 gives effect to the merger as if it had occurred on September 30, 2000,
and combines Gaiam's consolidated balance sheet as of September 30, 2000 with
Real Goods' balance sheet as of September 23, 2000. Since the fiscal years for
Gaiam and Real Goods differ, the unaudited pro forma combined condensed
statements of operations combine Real Goods' statements of operations for the
nine-month period ended September 23, 2000 and fiscal year ended March 31, 2000
with Gaiam's consolidated statements of operations for the nine-month period
ended September 30, 2000 and fiscal year ended December 31, 1999. It is expected
that upon the completion of the merger, Real Goods will change its fiscal year
to coincide with Gaiam.

  The pro forma combined condensed financial statements are not necessarily
indicative of the results of operations or the financial position, which would
have occurred, had the Real Goods merger been consummated at such times, nor are
they necessarily indicative of future results of operations or financial
position.

  The unaudited pro forma combined condensed financial statements should be read
in conjunction with the historical consolidated financial statements of Gaiam
and Real Goods including the notes thereto.  The consolidated financial
statements of Gaiam are incorporated by reference in this proxy
statement/prospectus and the consolidated financial statements of Real Goods are
contained in this proxy statement/prospectus.

     NOTES TO UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS

(1)  Adjustment to reflect the assumed rate of 10 shares of Gaiam common stock
to be issued for each share of Real Goods common stock as if the merger had
occurred as of September 30, 2000. The actual shares of Gaiam common stock to
be issued will be determined at the effective date of the merger based on the
actual shares of Real Goods' common stock outstanding at such date.
Additionally, a purchase price adjustment reflects the gift certificate
liability for issuance of a $1 gift certificate for each Real Goods common
stock share exchanged in the merger limited to $100 per shareholder.

(2)  These amounts reflect the elimination on consolidation of Gaiam's
investment in Real Goods against the net equity of Real Goods.

(3)  Gaiam and Real Goods will incur certain direct transaction costs
associated with the merger including transaction fees for investment bankers,
attorneys, accountants, financial printing and other related changes. These
costs are estimated to be approximately $500,000. Actual costs could not be
determined since the merger has not been completed. The pro forma combined
condensed balance sheet as of December 31, 1999, includes the effect of these
costs as if the merger occurred at such date.

                   OPINION OF REAL GOODS' FINANCIAL ADVISOR


General

          The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description.  The
following is a brief summary and general description of the valuation
methodologies utilized by Houlihan Lokey.  The summary does not purport to be a
complete statement of the analyses and procedures applied, the judgements made
or the conclusion reached by Houlihan Lokey or a complete description of its
presentation.  Houlihan Lokey believes, and so advised the Real Goods board of
directors, that its analyses must be considered as a whole and that selecting
portions of its analyses and of the factors considered by it, without
considering all factors and analyses, could create an incomplete view of the
process underlying its analyses and opinions.

          Real Goods retained Houlihan Lokey on behalf of the Real Goods board
of directors to render an opinion as to the fairness, from a financial point of
view, of the consideration to be received by the shareholders of Real Goods
pursuant to the merger. At the October 11, 2000 (the "Valuation Date") meeting
of the Real Goods board of directors, Houlihan Lokey presented its analysis as
hereinafter described and delivered its written opinion that, as of such date
and based on the matters described therein, the consideration to be received
pursuant to the merger is fair to the stockholders of Real Goods from a
financial point of view.

THE COMPLETE TEXT OF HOULIHAN LOKEY'S OPINION IS ATTACHED HERETO AS ANNEX C.
THE SUMMARY OF THE OPINION SET FORTH BELOW IS QUALIFIED IN ITS ENTIRETY BY
REFERENCE TO SUCH OPINION.  THE COMMON STOCKHOLDERS ARE URGED TO READ SUCH
OPINION CAREFULLY IN ITS ENTIRETY FOR A DESCRIPTION OF THE PROCEDURES FOLLOWED,
THE FACTORS CONSIDERED AND THE ASSUMPTIONS MADE BY HOULIHAN LOKEY.

Houlihan Lokey's opinion to the board of directors addresses only the fairness
from a financial point of view of the consideration to be received pursuant to
the merger, and does not constitute a recommendation to the Real Goods
shareholder as to how such shareholder should vote at the special meeting.
Houlihan Lokey's opinion does not address Real Goods' underlying business
decision to effect the merger.  Houlihan Lokey has not been requested to, and
did not, solicit third party indications of interest in acquiring all or part of
Real Goods.

In connection with the preparation of its opinion, Houlihan Lokey made such
reviews, analyses and inquiries as they deemed necessary and appropriate under
the circumstances.  Among other things, Houlihan Lokey:

     (i)    reviewed Real Goods' audited financial statements on Form 10-K for
            the fiscal years ended March 31, 1995 through 2000 and an internally
            prepared income statement for the four months ended July 22, 2000,
            which Real Goods' management has identified as being the most
            current financial statements available;

     (ii)   reviewed a draft of the merger agreement between Gaiam and Real
            Goods, dated October 4, 2000;

     (iii)  met with certain members of the senior management of Real Goods and
            Gaiam to discuss the operations, financial condition, future
            prospects and projected operations and performance of Real Goods and
            of Gaiam;

     (iv)   reviewed forecasts and projections prepared by Real Goods'
            management with respect to Real Goods for the years ending March 31,
            2001 through 2005;

     (v)    reviewed the historical market prices and trading volume for Real
            Goods' and Gaiam's publicly traded securities;

     (vi)   reviewed publicly available financial data for certain companies
            that it deemed comparable to Real Goods, and publicly available
            prices and premiums paid in other transactions that it considered
            similar to the merger; and

     (vii)  conducted such other studies, analyses and inquiries as it deemed
            appropriate.

In assessing the financial fairness of the consideration to be received pursuant
to the merger by Real Goods' public shareholders from a financial point of view,
Houlihan Lokey:

     (i)    analyzed the reasonableness of the trading value of Real Goods' and
            Gaiam's publicly traded equity securities;

     (ii)   independently valued the common equity of Real Goods and Gaiam using
            widely accepted valuation methodologies;

     (iii)  analyzed the reasonableness of the consideration being offered in
            the merger; and

     (iv)   analyzed the valuation implications to Real Goods' shareholders of
            various alternatives to the merger.


Valuation of Real Goods Trading Corp.

Assessment of Real Goods' Public Stock Price.  As part of its analysis, Houlihan
Lokey analyzed the trading price and volume of Real Goods' common stock.
Houlihan Lokey calculated the ratio of Real Goods' average daily volume (over
the most recent 90 days) for Real Goods' common stock to its float and total
shares outstanding.  Houlihan Lokey then compared Real Goods' ratios to similar
ratios of comparable publicly  traded companies.

Based on these analyses, it was Houlihan Lokey's opinion that Real Goods' common
stock (i) has a smaller public float than the comparable public companies, (ii)
does not trade as actively as the comparable public companies, and (iii) has
less analyst coverage than most of the comparable public companies.

Estimation of Real Goods' Fully Distributed Stock Price. Houlihan Lokey
completed an independent valuation of Real Goods using three standard valuation
approaches: the market multiple approach, the discounted cash flow approach and
the comparable transaction approach.  The market multiple approach involved the
multiplication of various earnings and cash flow measures by appropriate risk-
adjusted multiples.  Multiples were determined through an analysis of certain
publicly traded companies, selected on the basis of operational and economic
similarity with the principal business operations of Real Goods.  Earnings and
cash flow multiples were calculated for the comparable companies based upon
daily trading prices.  A comparative risk analysis between Real Goods and the
public companies formed the basis for the selection of appropriate risk adjusted
multiples for Real Goods.  The risk analysis incorporates both quantitative and
qualitative risk factors which relate to, among other things, the nature of the
industry in which Real Goods and the comparable companies are engaged.

For purposes of this analysis, Houlihan Lokey selected five publicly traded,
domestic companies involved in the direct mail catalogue industry.  The
companies include Coldwater Creek, Inc., DAMARK International, Inc., Hanover
Direct, Inc., Lands' End, Inc., and Lillian Vernon Corp.  Houlihan Lokey
informed the Real Goods Board that, because the market multiple approach is
based upon publicly traded prices of equity securities, the resulting valuation
indications are on a fully distributed, publicly traded equivalent basis.

In the second approach, the discounted cash flow analysis ("DCF"), Houlihan
Lokey used financial projections prepared by management.  The present value of
the cash flows and the terminal value was determined using a risk-adjusted rate
of return or "discount rate."  The discount rate, in turn, was developed through
an analysis of rates of return on alternative investment opportunities on
investments in companies with similar risk characteristics to the entity being
valued.  The discount rate is intended to reflect all risks of ownership and the
associated risks of realizing the stream of projected future cash flows.  It can
also be interpreted as the rate of return that would be required by providers of
capital to Real Goods to compensate them for the time value of their money, as
well as the risk inherent in the particular investment.

The third approach, the comparable transaction approach, also involved multiples
of revenue and cash flow.  Multiples analyzed in this approach involved
transactions for companies with operations similar in some manner to Real Goods'
operations where a controlling interest was acquired.  For purposes of this
analysis Houlihan Lokey analyzed 25 completed transactions between December 1996
and September 2000.

Based on the foregoing, Houlihan Lokey's independent valuation for Real Goods'
common stock is in the range of $1.50 to $1.70 per share, on a fully
distributed, freely traded basis.


Fairness of Consideration

Market Value Indications.  In determining the fairness of consideration to be
received pursuant to the merger, Houlihan Lokey considered the publicly traded
equity securities of both Real Goods and Gaiam.

     (i)    The relative valuation based on public market indicators for Real
            Goods and Gaiam implies that the consideration to be received
            pursuant to the merger yields an 11.0 percent premium as of the
            Valuation Date;

     (ii)   the one week average closing prices of each company's publicly
            traded securities indicates that the merger yields no premium;

     (iii)  the two week average closing prices of each company's publicly
            traded securities indicates that the merger yields a 5.0 percent
            premium;

     (iv)   the one month average closing prices of each company's publicly
            traded securities indicates that the merger yields a 6.9 percent
            discount; and


     (v)    the three month average closing prices of each company's publicly
            traded securities indicates that the merger yields a 22.6 percent
            discount.

Independent Valuation Indications.  In addition to the market value indications
discussed in the preceding paragraph, Houlihan Lokey has independently valued
both companies to determine the fairness of the consideration to be received
pursuant to the merger.  The independent valuation for Gaiam was limited by the
lack of projections for Gaiam, the very limited number of companies that are
truly comparable to Gaiam, and the fact that the capitalization of Gaiam's
potential growth is difficult to quantify.  Based on the independent valuation
approach, Houlihan Lokey concluded that the consideration to be received by the
merger was reasonably stated in the range of $1.34 to $1.61 per share, without
any value being attributed to the $1.00 Gaiam merchandise gift certificate, and
that the theoretical controlling interest value of Real Goods is $1.60 per
share.

Houlihan Lokey noted that the theoretical independent valuation conclusion was
within the range of the Merger price.  In addition, the merger price represented
a substantial premium to actual near term trading values; that is, the trading
prices as of the Valuation Date and the two week average closing prices of each
companies' publicly traded securities.


Assessment of Real Goods' Strategic Alternatives to the Merger

In evaluating the fairness of the merger, from a financial point of view,
Houlihan Lokey analyzed the expected value to Real Goods' minority public
shareholders of completing the merger and certain alternatives to the merger.
With regard to each alternative, Houlihan Lokey's analysis qualitatively
considered the valuation implications to Real Goods' minority public
shareholders, the probability of successfully completing each alternative, and
the cost and time to implement.

For purposes of this analysis Houlihan Lokey considered the following strategic
alternatives for Real Goods: (i) maintaining the present business plan; (ii)
sale or merger with a strategic buyer; (iii) sale to a financial buyer; (iv)
sale to management, (v) leveraged recapitalization, (vi) liquidation of business
units; and (vii) the merger.  Houlihan Lokey noted that of the strategic
alternatives considered, the merger appears to provide the greatest value to
Real Goods' common stockholders on a present value, risk-adjusted basis.

Houlihan Lokey relied upon and assumed, without independent verification, that
the financial forecasts and projections provided to them, and as adjusted based
on their discussions with management, were reasonably prepared and reflected the
best currently available estimates of the future financial results and condition
of Real Goods, and that there had been no material change in the assets,
financial condition, business or prospects of Real Goods since the date of the
most recent financial statements made available to them.

Houlihan Lokey has not independently verified the accuracy and completeness of
the information supplied to them with respect to Real Goods and does not assume
any responsibility with respect to it.  Houlihan Lokey has not made any
independent appraisal of any of the properties or assets of Real Goods.
Houlihan Lokey's opinion was necessarily based on business, economic, market and
other conditions as they existed and could be evaluated by Houlihan Lokey at the
date of their letter.

Houlihan Lokey is a nationally recognized investment banking firm with special
expertise in, among other things, valuing businesses and securities and
rendering fairness opinions.  Houlihan Lokey is continually engaged in the
valuation of businesses and securities in connection with mergers and
acquisitions, leveraged buyouts, private placements of debt and equity,
corporate reorganizations, employee stock ownership plans, corporate and other
purposes.  The Real Goods' board of directors selected Houlihan Lokey because of
its experience and expertise in performing valuation and fairness analysis.
Houlihan Lokey does not beneficially own nor has it ever beneficially owned any
interest in Real Goods or Gaiam.

Fees and Expenses.  Pursuant to an agreement dated September 26, 2000, Houlihan
Lokey was retained by Real Goods to analyze the fairness of the merger to the
minority public shareholders of Real Goods, from a financial point of view.
Real Goods has agreed to pay Houlihan Lokey a fee of $100,000, plus its
reasonable out-of-pocket expenses incurred in connection with the rendering of a
fairness opinion.  Real Goods has further agreed to indemnify Houlihan Lokey
against certain liabilities and expenses in connection with the rendering of its
services.

                      INTERESTS OF INSIDERS IN THE MERGER

  In considering the recommendations of Real Goods' board of directors with
respect to the merger proposals, Real Goods shareholders should be aware that
John Schaeffer, Real Goods' Chairman and Chief Executive Officer, has an
interest in the merger that is in addition to his interest as a Real Goods
shareholders generally.

Interests of John Schaeffer

  Following consummation of the merger, John Schaeffer will become President of
Gaiam's Real Goods division and will enter into an employment agreement with
Gaiam.  The employment agreement is expected to be for a term of two years and
provide, among other things, for:

-  a base salary of $125,000;

   if no arrangement is made such bonus will be 30% of Mr. Schaeffer's base
   salary;

-  a grant of options to acquire 30,000 shares of Gaiam's Class A common stock
   in accordance with Gaiam's 1999 Long Term Incentive Plan, with an exercise

   (which grant will be made upon commencement of the employment agreement);

-  severance pay of 12 months of base salary if Mr. Schaeffer is terminated for
   any reason other than "cause" (as defined in the agreement) or for no reason
   at all; and

   stock he receives in the merger to Gaiam or a third party identified by Gaiam
   (and restrictions on Mr. Schaeffer's ability to sell the remaining two-thirds
   of his Gaiam shares for a period of one year after consummation of the
   merger).

The employment agreement is also expected to contain a confidentiality agreement
by Mr. Schaeffer as well as an agreement not to compete with Gaiam for a period
equal to the greater of (x) three years after the date of the agreement and (y)
two years after the termination of his employment.

   In addition, Gaiam has consented to Real Goods' transfer of all rights under
Mr. Schaeffer's split dollar life insurance policy to Mr. Schaeffer or his
insurance trust and to any amendment or termination of agreements entered into
by Real Goods in connection with such policy.

Interests of Others

   Jeff Pescar, Real Goods' Vice President of Finance and Accounting, Ann
Killeen, Real Goods' Vice President of Information Systems, E-Commerce,
Inventory Planning and Circulation, and Kathy Asher, Real Goods' Vice President
of Operations, are each entitled to a two-month severance payment under their
respective employment agreements.  In addition, Ms. Killeen is entitled to
receive a $10,000 cash bonus if the merger is consummated while she is employee

   In addition, Gaiam has agreed to consult with Real Goods and use reasonable
best efforts to identify any Real Goods employees whose employment will be
terminated as a result of the merger.  Real Goods will pay or arrange for the
payment of severance to each Real Goods employee identified so long as any such
employee has been an employee of Real Goods for at least one year and such
employee continues employment until the date employment is terminated.
Severance will equal (a) two weeks of salary, plus (b) one additional week of
salary for each year of employment in excess of one year.  Gaiam has agreed

vacation and insurance plans, for any employment at Real Goods prior to the
merger.

     Under the merger agreement, Gaiam has agreed to, or cause the surviving
corporation in the merger to, comply with the indemnification agreements entered
into by Real Goods and its directors and officers.  Any new agreement or change,
amendment or waiver to any such existing agreement after the date of the merger
agreement will require consent of Gaiam.

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

    In addition to Gaiam's management's discussion and analysis of financial
condition and results of operations for the period presented below, we urge you
to read Gaiam's management's discussion and analysis of financial condition and
results of operations contained in Gaiam's Annual Report on Form 10-K for the
fiscal year ended December 31, 1999, which is incorporated herein by reference.
The quarterly condensed consolidated financial statements for the following
management discussion and analysis are included in the financial pages of this
document.

Nine months ended September 30, 2000 compared to nine months ended September 30,
1999

    Revenues increased 34.9% to $37.6 million for the nine months ended
September 30, 2000 from $27.9 million during the nine months ended September 30,
1999.  Gaiam's internal growth rate was 27% for the first nine months of 2000,
fueled primarily by the growth in sales to national retail chains and e-commerce
business.

    Gross profit, which consists of revenues less costs of sales, increased
34.6% to $22.5 million for the first nine months of 2000 from $16.7 million
during the same period in 1999.  As a percentage of revenue, gross profit
decreased to 59.9% in 2000 from 60.0% in 1999.

    Selling and operating expenses, which consist primarily of sales and
marketing costs, commissions and fulfillment expenses, increased 27.7%, less
than the revenue increase of 34.9%, to $17.4 million for the nine months ended
September 30, 2000 from $13.7 million for the same period in 1999.  As a
percentage of revenues, selling and operating expenses decreased to 46.4% in
2000 from 49.0% in 1999.

    Corporate, general and administrative expenses increased to $3.3 million
for the first nine months of 2000, compared to $2.8 million for the
corresponding period in 1999.  As a percentage of revenues, general and
administrative expenses decreased to 8.8% in 2000 from 10.2% in 1999.

    Operating income, as a result of the factors described above, increased to
$1.73 million for the nine months ended September 30, 2000 from $0.2 million
for the nine months ended September 30, 1999.

    Gaiam recorded $3,000 in other income during the nine months ended
September 30, 2000, compared to other income of $1.1 million for the comparable
period in 1999.  During 1999, Gaiam recognized gains on the sale of its
marketable securities of $1.4 million. Net interest expense declined to $132,000
for the first nine months of 2000 from $291,000 for the nine months ended
September 30, 1999, due to interest income generated during the third quarter of
2000.

    Minority interest in net income was $19,000 for the nine months ended
September 30, 2000 compared to a negative $74,000 for the same period in 1999.

    Income tax provision of $602,000 represented 37.5% of pre-tax income for
the nine months ended September 30, 2000, as compared to a $388,000 tax
provision, or 37.2% of pre-tax income, for the nine months ended September 30,
1999.

    Net income, as a result of the factors described above, increased 34.7% to
$983,000 for the nine months ended September 30, 2000 from $730,000 for the
comparable period in 1999.

Liquidity and Capital Resources

    Gaiam's capital needs arise from working capital required to fund our
operations, capital expenditures related to expansions and improvements to
Gaiam's infrastructure, development of e-commerce, and funds required in
connection with the acquisitions of new businesses and Gaiam's anticipated
future growth. These capital requirements depend on numerous factors, including
the rate of market acceptance of Gaiam's product offerings, the ability to
expand Gaiam's customer base, the cost of ongoing upgrades to Gaiam's product
offerings, the level of expenditures for sales and marketing, the level of
investment in distribution and other factors. The timing and amount of these
capital requirements cannot accurately be predicted. Additionally, Gaiam will
continue to evaluate possible investments in businesses, products and
technologies, and plans to expand sales and marketing programs and conduct more
aggressive brand promotions.

    During the first six months of 1999, Gaiam raised $1.45 million from the
private placement of 331,429 shares of Class A common stock and $1.425 million
in debentures. The privately placed shares were sold at $4.375 per share, and
the 8% convertible debentures matured on the earlier of one year after the date
of the debenture or the closing date of Gaiam's initial public offering. In
October 1999, we repaid $500,000 of the convertible debentures and, simultaneous
with the closing of the initial public offering, converted the remaining $1.475
million in debentures to 295,000 shares of Class A common stock.

    Gaiam's initial public offering of 1,705,000 shares of Class A common stock
at $5.00 per share was completed in October 1999. Simultaneous with this
offering, Gaiam converted $1.475 million in debentures to 295,000 shares of
Class A common stock, resulting in a total issuance of 2,000,000 shares. The
offering's underwriters also exercised their overallotment option for 102,861
additional shares during November 1999. Net proceeds to Gaiam, after deducting
all commissions and expenses associated with the offering, were $6.1 million.

    In May 2000, Gaiam consolidated its line of credit agreements with Wells
Fargo Bank into one agreement. The new credit agreement, which extends through
January 31, 2002, permits borrowings up to $5 million based upon the collateral
value of Gaiam's accounts receivable and inventory held for resale. Borrowings
under this agreement are secured by a pledge of Gaiam's assets. Principal
repayment of amounts borrowed under this line of credit agreement are due either
when the collateral value of Gaiam's accounts receivable and inventory drops
below prescribed levels or upon maturity of the agreements, whichever occurs
first. Borrowings under the Wells Fargo credit agreement bear interest at the
prime rate. The Wells Fargo credit agreement contains various financial
covenants and also prohibits Gaiam from paying dividends to shareholders.

    Gaiam's operating activities used net cash of  $4.9 million for the nine
months ended September 30, 2000 and used $5.1 million of net cash for the same
period in 1999.  Gaiam's net cash used by operating activities for 2000 arose
primarily from an increase in inventories in order to support additional revenue
growth, including store-within-store rollouts, and seasonal increases in prepaid
expenses.  Net cash used during 1999 was primarily a result of seasonal
increases in inventories and prepaid expenses associated with the increased
sales volumes generated during the fourth quarter.

    Gaiam's investing activities used cash of $872,023 for the nine months ended
September 30, 2000.  This use of cash arose primarily from costs associated with
the direct-to-consumer web site, and additional property and equipment purchases
to support our increasing volumes totaling $5.1 million.  On June 30, 2000,
Gaiam and Wholepeople.com ("Amrion"), a subsidiary of Whole Foods Market, merged
their Internet businesses into a newly formed company subsequently renamed
Gaiam.com, Inc.  In exchange for contributed Internet properties, Gaiam received
50.1% of Gaiam.com's common stock and Amrion received the remaining 49.9% of
Gaiam.com's common stock.  As part of this transaction, Amrion contributed $3
million in cash, a $3 million short-term note and other Internet assets to
Gaiam.com.  During the first nine months of 1999, Gaiam generated $942,820 in
cash from investing activities, largely from the sale of marketable securities.

    During the nine months ended September 30, 2000, Gaiam's financing
activities provided $6.9 million in cash.  In June 2000, Gaiam sold 6,000 shares
of Redeemable Series A Preferred Stock in Gaiam.com for a total consideration of
$6 million.


                                       55
<PAGE>

During the same period in 1999, Gaiam's financing activities provided $4.3
million in cash primarily from borrowing activities and the issuance of common
stock.

    As Gaiam continues to expand, we anticipate making additional investments in
web site design and technology, and, with additional planned business growth,
will be investing in additional capacity.

    We believe our available cash, cash expected to be generated from
operations, and borrowing capabilities will be sufficient to fund our operations
on both a short-term and long-term basis.  However, our projected cash needs may
change as a result of acquisitions, unforeseen operational difficulties or other
factors.

    In the normal course of our business, we investigate, evaluate and discuss
acquisition, joint venture, majority and minority investment, strategic
relationship and other business combination opportunities in the Lohas industry.
In the event of any future investment, acquisition or joint venture
opportunities, we may consider using then-available liquidity, issuing equity
securities or incurring additional indebtedness.

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

Second Quarter of 2000 Compared with Second Quarter of 1999

Net Sales

    Real Goods' net sales of $6,679,000 for the first six months of fiscal 2000
were down 18% from $8,101,000 for the first six months of fiscal 2000 due to
reduced catalog mailings and weaker sales of catalog and renewable energy
products due primarily to the extended sales malaise occurring after Year 2000
("Y2K") fears failed to materialize on January 1, 2000.

    Catalog division net sales in the first six months of fiscal 2001 decreased
by 35% to $2,624,000 from $4,066,000 in the first six months of fiscal year 2000
as a result of the post Y2K sales malaise mentioned above, weaker response rates
to Real Goods' catalogs, lower average orders and "cannibalization" by Internet
division sales which nearly doubled over the comparable period. Catalog division
sales were 39% of total net sales in the first six months of fiscal 2001 as
compared to 50% in the first six months of fiscal 2000.

    Internet division net sales increased 87% to $832,000 in the first six
months of fiscal 2001 from $445,000 in the first six months of fiscal 2000,
reflecting improvements in the website and the addition of new site partners. To
some extent, these increases were at the expense of the catalog division as Real
Goods believes that traditional catalog customers chose to order through the
Internet channel instead of the catalog channel. Internet division sales
amounted to 12% of total net sales in the first six months of fiscal 2001
compared with 5% of total net sales in the first six months of fiscal 2000.

    Real Goods' retail store division net sales increased 23% to $2,083,000 in
the first six months of fiscal 2001 from $1,701,000 in the first six months of
fiscal 2000 primarily due to the addition of the Los Gatos and West Los Angeles
stores. Sales included in the first six months of fiscal 2001 attributable to
the new stores total $537,000. Same store sales dropped 9% from $1,701,000 in
the first six months of fiscal 2000 to $1,546,000 in the first six months of
fiscal 2001 reflecting a weaker interest in renewable energy products on the
part of the consumers due to the extended post Y2K sales malaise. Retail
division sales amounted to 31% of total net sales in the first six months of
fiscal 2001 compared to 21% of total net sales in the first six months of fiscal
2000.

    Real Goods' renewable energy sales decreased 44% to $1,059,000 in the first
six months of fiscal 2001 from $1,890,000 in the first six months of fiscal
2000. Fiscal 2000 revenues included a single $182,000 sale of a solar system to
a winery in Northern California. The renewable energy industry as a whole has
experienced a marked drop in consumer interest following Y2K although Real Goods
expects demand to pick up soon due to increasing gasoline and utility company
prices. Renewable energy sales amounted to 16% of total net sales in the first
six months of fiscal 2001 compared with 23% of the total net sales in the first
six months of fiscal 2000. The California Energy Commission program, begun in
March 1999 as an incentive to install renewable energy systems where customers
can buy solar systems for up to 50% off retail price, is mandated by the
California legislature to continue for a minimum of four years from inception.
Real Good's Renewable Energy Division aggressively markets the CEC program.

    For the three months ended September 23, 2000, Real Goods' net sales
decreased 13%, or $507,000, to $3,477,000 compared to $3,984,000 in the previous
period for the reasons cited above. Net catalog sales of the three months were
down 33% to $1,338,000 compared to $1,989,000 for the same period in the
previous year. Internet sales for the three months were up 116% to $453,000,
compared to $210,000 for the same period in the previous year. Retail stores
sales for the three months were $1,185,000, an increase of 30% from the previous


                                       57
<PAGE>

year's comparable sales of $911,000. Reneable energy sales for the three months
were $488,000, a decrease of 44% from the previous year's comparable sales of
$874,000.

Gross Profit

    Gross profit for the first six months of fiscal 2001 was $2,531,000 or 38%
of sales compared with $3,279,000 or 40% for the first six months of fiscal
2000. Overall margins declined with the relatively lower proportion of catalog
sales, which historically produce Real Goods' highest gross profit as a
percentage of sales. The decline in margin also reflects aggressive sale pricing
on Y2K product overstocks in the first six months of fiscal 2001 which succeeded
in reducing inventory by over $520,000. Catalog sales had a gross profit of 42%
or $1,115,000 for the first six months of fiscal 2001 compared with 45% or
$1,840,000 in the first six months of fiscal 2000 due to the Company's decision
to aggressively price Y2K product overstocks in catalog mailings and sales
fliers to reduce inventory. Retail stores division gross profit for the first
six months of fiscal 2001 was 37% or $773,000 and was down from the 39% margin
level or $656,000 in the first six months of fiscal 2000. This decrease reflects
increased levels of items on sale to reduce inventory. Renewable energy division
sales, including design and consulting fees for solar, wind and hydro projects,
had a gross margin of 25% or $270,000 in the first six months of fiscal 2001
compared to a gross margin of 31% or $583,000 in the first six months of fiscal
2000. The drop in percentage in fiscal 2001 results from a one-time large sale
completed at less than a 20% margin. Renewable energy sales typically have lower
gross margins which tend to reduce Real Good's overall average gross margin.

    For the three months ended September 23, 2000, gross profit decreased to
38%, or $1,306,000 compared to 41%, or $1,634,000 for the reasons cited above.
The catalog division provided a gross profit of $563,000 or 42% compared to
$911,000 or 46% for the previous period. The internet division provided a gross
profit of $188,000 or 42% compared to $96,000 or 46% for the previous period.
The retail division provided a gross profit of $425,000 or 36% compared to
$354,000 or 39% for the previous period. The renewable energy division provided
a gross profit of $127,000 or 26% compared to $273,000 or 31% for the previous
period.

Operating Expenses and Income

    Real Good's selling, general and administrative expenses were $4,033,000, or
60% of net sales in the first six months of fiscal 2001 compared with $3,807,000
or 47% of net sales in the first six months of fiscal 2000. Selling, general and
administrative expenses amounted to $2,100,000, 60% of sales, for the quarter
compared to $1,941,000, or 49% of sales, for the previous year's comparable
quarter. This increase in percentage reflects the drop in sales and increases in
catalog and printing, advertising, supplies, depreciation, and rent expense.
These increases were offset by decreases in the areas of labor and benefits,
equipment expense, utilities, training, recruitment, and general administrative
expense. In the first six months of fiscal 2001, Real Goods had net interest
income of $42,000 compared with net interest income of $8,000 in the first six
months of fiscal 2000. For the quarter, net interest and other income was
$27,000 compared with $3,000 for the previous year's quarter.

Earnings

    For the first six months of fiscal 2001, Real Goods incurred a pre-tax loss
of $1,460,000 and a net loss of $1,095,000, or $.23 per share compared to a pre-
tax loss in the first six months of fiscal 2000 of $520,000 and a net loss of
$338,000 or $.08 per share. For the quarter, Real Goods incurred a pre-tax loss
of $767,000 and a net loss of $575,000 or $0.12 per share as compared to a pre-
tax loss of $304,000 and a net loss of $198,000 or $0.05 per share in the
previous year's quarter. Weak sales due to the extended post Y2K malaise and
lower margins due to sale prices reducing inventory levels were the primary
reasons for these increased losses. Real Goods typically experiences seasonality
with sales and earnings building toward the fiscal third quarter (the holiday
season) which is historically Real Goods' strongest and most profitable quarter.



                                       58
<PAGE>

Income Tax Benefit

    The income tax benefit used by Real Goods was 25% in the first six months of
fiscal 2001 compared with 35% in the first six months of fiscal 2000. These
rates represent the projected realizable rates expected by management for each
fiscal year.

Liquidity and Capital Resources

    For the first six months of fiscal 2001, cash used in operations was
$1,204,000 primarily due to the net loss and reductions in accounts payable.
Overall, the Company generated $1,192,000 from net investing activities and used
$155,000 in its financing activities. The net effect of these activities was to
decrease cash from $876,000 at March 31, 2000 to $709,000 at September 23, 2000.
Management believes that cash flow from operations together with bank debt
financing and existing cash reserves will be sufficient to fund the Company's
operations through fiscal 2001.

Fiscal Year 2000 Compared with Fiscal Year 1999

Net Sales

    Real Goods reported a 1.3% increase in net sales to $18,979,000 for fiscal
2000, compared to $18,736,000 for fiscal 1999.

    In fiscal 2000, Real Goods changed its presentation (see Note 1 to the
financial statements) and included freight collected in sales and freight out
expense in cost of sales. Previously, these amounts were included in selling,
general and administrative expenses. The amounts in fiscal 1999 have been
reclassified to conform to the new presentation.

    Catalog sales decreased 1.8% to $11,699,000, or 61.6% of net sales in fiscal
2000, compared to $11,914,000 or 63.6% in the prior year.  Internet sales
(included in the catalog) division were $1,482,000 or 7.8% of sales for fiscal
2000 compared with $551,000, or 2.9% in fiscal 1999. Real Goods mailed 4,167,500
catalogs in fiscal 2000 compared to 4,431,500 catalogs in fiscal 1999, a
decrease of 6%.   Catalog division sales per catalog increased from $2.69 per
catalog mailed to $2.81 per catalog and is attributed to the effect of Internet
sales growth. Included in net catalog sales for the years ended March 31, 2000
and 1999 are shipping and handling fees collected from customers of $1,256,000
and $1,373,000, respectively.

    Retail store sales increased 8.1% to $4,046,000, or 21.3% of net sales in
fiscal 2000, compared to $3,743,000 or 20.0% of net sales in the prior year.
Real Goods opened a new store in Los Gatos, California in November, 1999 which
contributed $302,000 in total revenue for fiscal 2000. Therefore, Real Goods had
four retail stores and one outlet store open with 15,500 square feet of retail
selling space at the end of fiscal 2000 compared with 14,300 square feet of
selling space in fiscal 1999. On a comparable basis, excluding Los Gatos, retail
sales for fiscal 2000 were $3,744,000 compared to $3,743,000 for fiscal 1999. A
sharp drop in Real Goods' sales of renewable energy products in the fourth
fiscal quarter contributed to the of sales results in fiscal 2000.

    Renewable energy sales increased 5.0% to $3,234,000, or 17.0% of net sales
in fiscal 2000, compared to $3,079,000, or 16.4% of net sales in the prior year.
The increase in this area of Real Goods' business was primarily due to Y2K
concerns but also reflects the public's increased awareness of energy
utilization and a desire to safeguard the earth's natural resources, energy
incentive credit programs sponsored by many state agencies in conjunction with
the deregulation of utilities, and customers' interests in potential renewable
energy solutions. Real Goods also continues to market its services to the "eco-
tourism" market. Included in net renewable energy sales for


                                       59

fiscal years 2000 and 1999 are shipping and handling fees collected from
customers of $144,000 and $143,000, respectively.

Gross Profit

    Gross profit amounted to $7,834,000, or 41.3% of net sales in fiscal 2000
compared to  $7,832,000, or 41.8% of sales in fiscal 1999. The relative flatness
of gross profit is attributable to the lack of growth in the catalog division.

    Catalog sales had a 2.4% decrease in gross profit of $5,327,000 or 45.5% of
catalog net sales in fiscal 2000, compared to $5,459,000 or 45.8% of catalog net
sales in the prior year.  The slight margin decrease is attributable to the
reduction in net shipping income, the reduction of prices on selected
merchandise to promote sales, and increased costs of products which were not
passed through to customers for competitive reasons. Net shipping income
included in catalog gross profit was $240,000 in fiscal 2000 and $332,000 in
fiscal 1999.

    Retail stores sales had a gross profit of $1,519,000 or 37.5% of retail net
sales in fiscal 2000 compared to $1,400,000 or 37.4% of retail net sales in
fiscal 1999.  This margin percentage reflects the same mix of renewable energy
and retail product as in fiscal 1999.

    Renewable energy sales had a gross profit of $988,000 or 30.6% of net
renewable energy sales compared to $973,000 or 31.6% of net renewable energy
sales for the prior year. This decrease in gross profit percentage is
attributable to higher product costs and increased competition in the renewable
energy field. Renewable energy products have generally lower profit margins. Net
shipping income included in renewable gross profit was $30,000 in fiscal 2000
and $32,000 in fiscal 1999.

Operating Expenses

    Selling, general, and administrative expenses were $9,402,000 or 49.5% of
sales in fiscal 2000, compared to $8,497,000 or 45.4% of sales in the prior
year. Increases in expenses occurred in the areas of labor and benefits, catalog
expenses, supplies, depreciation, rents, utilities, travel, and general
corporate expenses. These increases more than offset the decreases that occurred
in postage, purchased services, and recruitment costs. Many of the expense
increases were attributable to costs associated with moving Real Goods
headquarters from Ukiah to Santa Rosa, California.

Other Income and Expense

    In fiscal 2000, interest expense was $47,000 and interest income was
$110,000, resulting in a net interest income of $63,000. In the previous fiscal
year, interest expense was $48,000 and interest income was $90,000, for a net
interest income of $42,000. Real Goods had lower interest expense and higher
interest income due to the cash position following the equity investment by
WholePeople.com.

    Real Goods recorded a $354,000 net loss on write down and disposition of
assets in fiscal 2000. In fiscal 1999, a $1,000 net gain was recorded on the
sale of assets. In fiscal 1999, Real Goods recorded a $10,000 write down of the
land and building in Amherst, Wisconsin to reflect the estimated net realizable
value of the property held for sale.

Income Taxes

    Income tax benefits as a percentage of pretax loss were 31% in fiscal 2000
due to Real Goods' reported loss, compared to a tax benefit of 24% for the
previous year. The applied tax rate reflects Real Goods' actual


                                       60
<PAGE>

experience of the turnaround in timing differences and the expected utilitzation
of net operating loss carryforwards in future periods.

Net Loss

    For the year ended March 31, 2000, Real Goods had a loss before tax benefit
of $1,859,000 and a net loss of $1,290,000 or $0.29 per share. In the previous
year, Real Goods had a loss before tax benefit of $632,000 and a net loss of
$482,000 or $0.12 per share.

Liquidity and Capital Resources

    During the fiscal year ended March 31, 2000, cash of $1,172,000 was used in
the business.

    Real Goods used $2,037,000 of cash in operations, primarily for inventory
and Real Goods' operating loss.

    Real Goods used $2,701,000 of cash in investing activities for purchases of
property, equipment and improvements, (primarily for retail stores) and computer
equipment and assets, and purchase of marketable securities.

    Cash provided by financing activities was $3,566,000 due primarily to the
investment in Real Goods by WholePeople.com of $3,578,000.

    The net effect of all of Real Goods' activities was to decrease Real Goods'
cash by $1,172,000 to $876,000 at the end of the period from $2,048,000 at the
beginning of the period. Additional funds in the form of short-term investments
in marketable securities are available to Real Goods to fund current operations
and totaled $1,568,000 at March 31, 2000.

    Real Goods extended its $1,500,000 line of credit through February 2001 to
use for seasonal fluctuations in inventory levels as well as operating expenses;
Real Goods did not use the line of credit during fiscal 2000 except to support
letters of credit. Management believes that cash flow from operations together
with bank debt financing and existing cash reserves will be sufficient to fund
Real Goods' operations through fiscal 2001.

Effects of Inflation

    The overall effects of inflation on Real Goods' business during the periods
discussed were not material.

Fiscal Year 1999 Compared with Fiscal Year 1998

Net Sales

    Real Goods reported a 1.1% increase in net sales to $17,219,000 for fiscal
1999, compared to $17,034,000 for fiscal 1998. Catalog sales decreased 12.4% to
$10,540,000, or 61.2% of net sales in fiscal 1999, compared to $12,029,000 or
70.6% in the prior year. In fiscal 1999, the Earth Care catalog was
discontinued. This catalog contributed $1,842,000 to net sales in fiscal 1998.
Excluding the Earth Care catalog, catalog sales were $10,187,000 in fiscal 1998
meaning comparative catalog sales increased 3.5%. Real Goods mailed 4,716,500
catalogs in fiscal 1999 compared to 6,533,500 catalogs in fiscal 1998, a
decrease of 27.8%. Real Goods attributes the 21.2% increase in net sales per
catalog (from $1.84 to $2.23) to more focused marketing strategies and
elimination of the Earth Care catalog.



                                       61
<PAGE>

    Retail store sales increased 28.6% to $3,743,000, or 21.7% of net sales in
fiscal 1999, compared to $2,910,000 or 17.1% of net sales in the prior year.
Real Goods had its three retail stores and one outlet store open for the full
twelve months of fiscal 1999 and had 14,300 square feet of retail selling space
during fiscal 1999 compared with a weighted average of 13,175 square feet of
selling space in fiscal 1998, an 8.5% increase.  In fiscal 1998  Real Goods
moved its outlet store from Ukiah to Berkeley, California, adjacent to its
Berkeley retail store. It also closed its Snow Belt store in Amherst, WI in
September 1997.  As a result, fiscal 1999 contained 48 store months compared
with 45.7 store months in fiscal 1998. Real Goods hired a Retail Director in
fiscal 1999 and believes this additional focus contributed to the sales growth
in fiscal 1999.

    Renewable energy sales increased 43.9% to $2,936,000, or 17.1% of net sales
in fiscal 1999, compared to $2,041,000, or 12.0% of net sales in the prior year.
The increase in this area of Real Goods' business is due to the public's
increased awareness of energy utilization and a desire to safeguard the Earth's
natural resources, energy incentive credit programs sponsored by many state
agencies in conjunction with the deregulation of utilities, and customers'
interests in potential Y2K renewable energy solutions. Real Goods also continues
to market its services to the "eco-tourism" market.

Gross Profit

    Gross profit amounted to $7,467,000, or 43.4% of net sales in fiscal 1999
compared to $8,198,000, or 48.1% of sales in fiscal 1998. This decrease of
$731,000 of margin, or 4.3 margin points, is attributable to the following:
establishment of inventory reserves ($232,000 or 1.3 margin points), a higher
proportion of renewable sales in the retail and renewable energy divisions
($257,000 or 1.5 margin points), increased cost of products ($158,000 or 1.0
margin points) and clearance of old stock at reduced prices ($84,000 or .5
margin points).

    Catalog sales had a 3.7% decrease in gross profit of $5,126,000 or 48.6% of
catalog net sales in fiscal 1999, compared to $6,287,000 or 52.3% of catalog net
sales in the prior year.  The margin decrease is attributable to the
establishment of inventory reserves and obsolete items necessary to accommodate
discontinued product, clearance sales and increased costs of products which were
not passed through to customers for competitive reasons.  Retail stores sales
had a gross profit of $1,400,000 or 37.4% of retail net sales in fiscal 1999
compared to $1,170,000 or 40.2% of retail net sales in fiscal 1998.  This
decrease in margin is related primarily to the higher proportion of low margin
renewable energy sales and a $40,000 reserve provided for obsolete and slow-
moving products.

    Renewable energy sales had a gross profit of $941,000 or 32.1% of net
renewable sales compared to $687,000 or 33.7% of net renewable sales for the
prior year. This decrease is attributable to higher product costs.

Operating Expenses

    Selling, general, and administrative expenses were $8,132,000 or 47.2% of
sales in fiscal 1999, compared to $8,562,000 or 50.3% of sales in the prior
year. Decreases in expenses occurred in the areas of catalog expenses (due
primarily to the discontinuation of the Earth Care catalog), advertising,
postage and freight expense, supplies and utilities. These decreases more than
offset the increases that occurred in labor and benefits, depreciation, rent,
purchased services, and recruitment costs. Some of the expense increases were
attributable to costs associated with moving the Company headquarters from Ukiah
to Santa Rosa, California.

Other Income And Expense

    In fiscal 1999, interest expense was $48,000 and interest income was
$90,000, resulting in a net interest income of $42,000. In the previous fiscal
year, interest expense was $95,000 and interest income was $24,000, for a net
expense of $71,000. The Company had lower interest expense and higher interest
income due to the cash


                                       62
<PAGE>

generated by its direct public offering that commenced in August 1997 and ended
on June 30, 1998. Real Goods recorded a $1,000 net gain on the sale and
disposition of assets in fiscal 1999. In fiscal 1998, a $13,000 net loss was
recorded on the sale of assets. In fiscal 1999, Real Goods recorded a $10,000
write down of the land and building in Amherst, Wisconsin compared to a $30,000
write down in fiscal 1998 to reflect the estimated net realizable value of the
property held for sale.

Income Taxes

    Income tax benefits as a percentage of pretax loss were 24% in fiscal 1999
due to Real Goods' reported loss, compared to a tax benefit of 33% for the
previous year. Real Goods believes that the applied tax rate accurately reflects
its actual experience.

Net Loss

    For the year ended March 31, 1999, Real Goods had a loss before tax benefit
of $632,000 and a net loss of $482,000 or $0.12 per share. In the previous year,
Real Goods had a loss before tax benefit of $478,000 and a net loss of $322,000
or $0.09 per share.

Liquidity And Capital Resources

    During the fiscal year ended March 31, 1999, cash of $371,000 was provided
by operations primarily due to changes in working capital.

    Real Goods used $730,000 of cash in investing activities for purchases of
property, equipment and improvements, primarily for computer equipment and
assets associated with the new corporate headquarters.

    Cash provided by financing activities was $1,106,000 due primarily to Real
Goods' direct public offering, offset by an increase in notes receivable, debt
repayments and purchases of common stock.

    The net effect of all of Real Goods' activities was to increase Real Goods'
cash by $747,000 to $2,048,000 at the end of the period from $1,301,000 at the
beginning of the period.

    Real Goods extended its $1,500,000 line of credit through August 1999 to use
for seasonal fluctuations in inventory levels as well as operating expenses;
Real Goods did not use the line of credit during fiscal 1999 except to support
letters of credit. Real Goods' management believes that cash flow from
operations together with bank debt financing and existing cash reserves will be
sufficient to fund Real Goods' operations through fiscal 2000.

Effects Of Inflation

    The overall effects of inflation on Real Goods' business during the periods
discussed were not material.


Year 2000 Preparedness and Results

    As of September 23, 2000, Real Goods has not experienced any significant
business disruptions as a result of Y2K issues.  Real Goods addressed the Y2K
problem through a comprehensive evaluation and improvements of its hardware,
software, communications and key external vendors and suppliers.  The cost of
the evaluation and upgrades was approximately $250,000, most of which was
incurred in the normal course of business as periodic software and hardware
upgrades.

                             REAL GOODS' BUSINESS

    In addition to the description of Real Goods' business set forth below, we
urge you to read the description of Gaiam's business contained in its Annual
Report on Form 10-K for the fiscal year ended December 31, 1999, as well as
additional information contained in its other periodic and current reports filed
with the SEC during 2000.

    Mission Statement: To promote and inspire an ecologically sustainable
future.

    Introduction. Real Goods sells primarily healthy living, environmental, and
renewable energy products through mail order catalogs, direct sales, retail
stores and its Internet site (www.realgoods.com).

    Real Goods mails catalogs under the names of Real Goods, Chelsea Green
Junction, Real Goods News, and the Renewable Energy Products Catalog, Real Goods
Renewables. Real Goods also sells renewable energy products directly to its
customers through its renewable energy division, Real Goods Renewables. Real
Goods' four retail stores are located in Hopland, Berkeley, Los Gatos, and West
Lost Angeles, California. Real Goods also has an outlet store inside its
Berkeley store.

Real Goods' Markets

    Real Goods serves several related market segments within the single line of
business of specialty retailing.  The "Healthy Living & Environmental Products
Market" consists of catalog customers who wish to pursue more energy conserving
and wholesome lifestyles with a belief in preserving the earth's resources in a
sustainable manner. Consumers in this market tend to live in urban and suburban
areas served by the conventional electric utility power grid.

    Several regional markets are served by Real Goods' retail stores. Each of
the four stores carries substantially all of the products in the catalogs but
also carries environmental, healthy living and clothing products as well as
unique regional products. Real Goods' demonstration retail store at the Solar
Living Center in Hopland, California was built with sustainable building
materials, including straw bale construction, and is 100% powered by renewable
energy systems. Over 130,000 visitors come to the Solar Living Center every
year. Real Goods uses its outlet store in Berkeley, California, to reduce
overstocks, returns and discontinued products.

    Real Goods' original focus, the "Renewable Energy Market," consists of
homeowners and others living and working without the benefit of the traditional
electric company power grid who generate their own electricity using solar,
wind, and hydro power systems. Real Goods has also identified eco-tourism and
the commercial market as a promising sub market for its renewable energy sales.
As the price of renewable energy products (particularly photovoltaic (solar
electric) modules) declines, Real Goods believes this market will become more
mainstream.

    In conjunction with its product marketing efforts, Real Goods has always
emphasized the "Consumer Education Market."  Real Goods produces and sells a
wide variety of educational materials through its catalogs and retail stores and
has a successful co-publishing relationship with Chelsea Green Publishing
Company of Vermont with whom it has co-published over 20 book titles.

    Healthy Living and Environmentally Related Products Market. Using both mail
order catalogs and the Internet, Real Goods markets energy saving conservation
devices, healthy living and environmentally related products, durable tools, and
educational and well-made gifts to urban and suburban dwellers.  Approximately
68% of Real Goods' total sales in fiscal 2000 were derived from catalogs, down
from 75% in 1999.  Real Goods mailed approximately 4,167,500 catalogs in fiscal
2000, compared to 4,431,500 in fiscal 1999 as Real Goods focused its


                                       64
<PAGE>

marketing strategy and diversified further into the Internet. Approximately 7.8%
of Real Goods' total sales in fiscal 2000 were made over the Internet, up from
2.9% in fiscal 1999; certain of those sales were of renewable energy products.

    The environmentally related products offered by Real Goods comprise a full
spectrum of energy-efficient lighting equipment; high efficiency appliances;
water saving devices such as low-flow showerheads, low-flush toilets and faucet
aerators; recycled paper products including toilet paper, paper towels and
facial tissue;  bed and bath products, organic cotton apparel, and household
products including a wide variety of non-toxic cleaners.  Real Goods also sells
water and air purification devices, health-related products, solar tools, and
durable tools to this same customer base.

    Regional Retail Market.  Real Goods' retail stores serve as demonstration
centers for its mail order catalog and renewable energy products.  Real Goods
markets energy saving devices, healthy living and environmentally related
products, educational and well-made gifts and unique regional products in each
of its retail stores. Real Goods' four retail stores accounted for 21.3% of
total sales in fiscal 2000 compared to 20% in fiscal 1999. Real Goods had 15,500
square feet of retail space during fiscal 2000, up from 14,300 square feet in
fiscal 1999.

    The Solar Living Center ("SLC"), which opened in 1996 in Hopland,
California, is a twelve acre demonstration site that is the home of Real Goods'
flagship store. The 4,200 square foot retail store is constructed of adobe-like
covered rice straw bales and has a utility intertie system with Green Mountain
Energy. Real Goods' 10 kilowatt photovoltaic array and 3 kilowatt wind generator
can seasonally produce more power than is necessary for the site; Real Goods
sells the excess power to Green Mountain. The Solar Living Center embodies Real
Goods' core principles and provides an opportunity to demonstrate the
practicality of living and working on a low consumption, environmentally
sensitive and renewable energy basis. The site is immediately adjacent to
Highway 101 in Hopland, California, and has been of interest both to residents
of Northern California and to tourists who have made it a destination. Over
150,000 visitors came to the SLC in fiscal 2000. Real Goods believes that the
Solar Living Center remains important to Real Goods' future. In September 1999,
a 132 kw array was constructed by GPU AstroPower on the site. Energy from the
array is sold to Green Mountain Energy under a long term contract.

    In addition to serving as a demonstration center for renewable energy
products and catalog products, the Hopland store also offers retail products,
some of which are unique to the Northern California bio-region. Many of these
unique products are handmade or made in small quantities that are not suitable
for mail order. Approximately two-thirds of the Hopland store's products are
catalog and renewable energy items; one third are unique retail items.

    The 4,800 square foot Berkeley store serves as an urban demonstration center
for Real Goods' catalog and renewable energy products. In January 1998, Real
Goods opened a 1,500 square foot outlet store which recently was moved inside
the Berkeley store. Real Goods conducts its clearance programs through this
store.

    The Los Gatos store, 3,400 square feet, was opened in November 1999 and
serves an affluent suburban market. It is located in a mall with a Whole Foods
Market store. The West Los Angeles store is a 3,100 square foot store that
opened in late May, 2000. The store is situated adjacent to a Whole Foods Market
store and services a densely populated affluent area.

    Renewable Energy Products Market. Real Goods Renewables offers power systems
for the eco-tourism market and for domestic remote homes using renewable sources
of energy including photovoltaic (solar electric), hydroelectric and wind
electric, as well as emerging renewable energy technologies such as hydrogen
fuel cells and a new generation of photovoltaic cells. Real Goods Renewables
endeavors to provide a broad array of appliances and other system components for
most aspects of the independent power systems lifestyle. These products include
battery storage systems, power conversion devices, charge controllers, meters,
low voltage water pumping systems,


                                       65
<PAGE>

solar and propane gas water heaters, high efficiency refrigerators, solar
cooling devices, composting toilets and a wide variety of low-voltage household
appliances.

    The traditional customers for these power systems have been owners of remote
homes in excess of one-quarter mile from the power companies' lines in the
United States and remote villages in third world countries.  Real Goods believes
over 26,000 homes have used its products to migrate to renewable energy
primarily through solar systems.  In addition Real Goods believes that the
market for small-scale solar electric systems in the developing third world
market is increasing significantly.  Real Goods is seeking to serve the domestic
remote home market directly and to develop strategic alliances to address the
developing third world market through product sales and education.

    President Clinton's "million solar roofs" initiative has brought much
interest in renewable energy to mainstream America. Currently the federal
government is proposing tax credits for homeowners installing renewable energy
systems. The U.S. Department of Energy continues to provide funds for
photovoltaic installations via the Team UP program. The California Energy
Commission is offering a significant (up to 50%) renewable energy rebate program
for homeowners who install utility intertie systems. Many other states have, or
will soon have, similar rebate programs. Real Goods has offered assistance in
fulfillment of the program requirements for its customers and is well positioned
to take advantage of these offers.

    Real Goods Renewables markets its products through the Real Goods Renewables
Catalog, a technical catalog mailed to the more sophisticated renewable energy
buyer, as well as through Real Goods' own Solar Living Sourcebook and other
educational materials, and by direct sales. Real Goods' technical staff is fully
trained in energy system sizing and specializes in designing solar systems of
all sizes.

    Consumer Education Activities. Real Goods has traditionally emphasized
consumer education as part of its mission and continues to produce and sell a
wide variety of educational materials. Real Goods has adopted the slogan
"knowledge is our most important product." Real Goods' primary product for this
market is the tenth edition of its Solar Living Sourcebook, a 575 page textbook
that Real Goods periodically revises, which features all of Real Goods'
renewable energy products. The Solar Living Sourcebook is currently distributed
by an independent publisher (Chelsea Green) as well as by Real Goods itself.
Over 125,000 copies of this book have been sold in 47 countries. Real Goods also
markets many publications on specific aspects of renewable energy conservation
and sustainable living within its catalogs and in its retail stores. Real Goods
does not spend material amounts for research and development.

    Real Goods has established a successful co-publishing relationship with
Chelsea Green Publishing Company of Vermont. Through this relationship, twenty
books have been co-published under the "Real Goods Solar Living Series" imprint,
including Real Goods' own Solar Living Sourcebook. Real Goods believes that
these co-publishing efforts have significantly boosted its position as an
education leader in the sustainability movement.

    Real Goods has contributed to a non-profit corporation which operates the
Institute for Solar Living (ISL). Originally founded by Real Goods and currently
in its ninth season, the Institute for Solar Living offers over 40 educational
seminars each year for individuals on a variety of topics such as "Planning and
Building Your Renewable Energy Home" and "Strawbale Construction." The seminars
are taught by the Institute employees and by third-party industry specialists.
The Institute creates increased consumer awareness with regard to renewable
energy products and rents the Solar Living Center as a demonstration site. The
ISL sponsors an annual energy festival, SolFest, every summer which brings
5,000-10,000 visitors onsite to experience workshops, speakers, renewable energy
demonstrations, and entertainment. Real Goods believes that SolFest contributes
significantly to its educational efforts and enhances brand recognition.

                                       66
<PAGE>

    Internet Site. Real Goods has established a website (www.realgoods.com)
which provides Real Goods with an alternative channel for offering its products
and explaining its mission, history, programs and products. Real Goods believes
that its customers on its website can find the largest array of environmental
and healthy living products anywhere in the world. In fiscal 2000 Real Goods
sold $1,482,000 worth of products through its website, representing 269% of the
previous year's sales. Real Goods also maintains an innovative bulletin board on
its website for interested shareholders and prospective stock purchasers to
agree upon the purchase and sale of Real Goods' common stock without the
intermediation of stock brokers. Transactions are without cost to purchasers,
and sellers pay only transfer fees. Real Goods received the approval of the
staff of the Securities and Exchange Commission for this program in 1996, and
this approval was the first of its kind. There can be no assurance that Real
Goods will continue to offer this service to its shareholders in the future.

Vendors

    Real Goods currently purchases its products from a vendor base of more than
700 suppliers, none of which accounts for more than 3.5% of Real Goods'
purchases. Real Goods' ten largest vendors account for 24.6% of purchases. The
four largest annual purchases are from vendors who sell renewable energy
products, including solar electric modules, high efficiency appliances, and
inverters (power conditioning equipment). While there are many suppliers of
these products, Real Goods has chosen to limit the majority of its renewable
energy purchases to four vendors: Astropower, a distributor of solar modules;
Applied Power, a distributor of solar modules and other equipment manufactured
by Siemens Solar Industries; Kyocera, a distributor of solar modules and high
efficiency refrigerators; and Trace Engineering, a manufacturer of inverters and
other solar electric controls.

    Real Goods has had long-term relationships with all of these vendors.
Because many of the renewable energy products are relatively new, the number of
suppliers for these products can be limited, and Real Goods, from time to time,
may face short-term dependencies upon certain manufacturers for these products.
However, Real Goods believes it would not face long-term difficulties in
securing alternate sources of supply for such products if it experiences an
interruption in its current supply. Real Goods believes such an interruption
would be brief and is not likely to have a long-term material adverse effect on
Real Goods' orders and sales revenues for the period affected.

    Real Goods generally does not enter into long-term contracts with its
suppliers because adequate alternative sources for most products exist allowing
flexibility to take advantage of competitive price fluctuations or improvements
in technology or quality by not being obligated pursuant to long-term
arrangements. As a result, there can be no assurance that Real Goods will not be
subject to unanticipated cost increases or shortages of supply.

Seasonality

    Forty percent of Real Goods' revenues are realized in its third fiscal
quarter, which ends on December 31. Renewable energy products are also subject
to seasonality, but the cycle for these products is the inverse of the
environmental, conservation and gift products, which lessens the effect of the
holiday season on Real Goods' overall sales. Real Goods' fiscal year ends on
March 31. Real Goods' sales generally increase sequentially over the first,
second and third fiscal quarters, and generally decline in the fourth fiscal
quarter. It is possible that such seasonal effects will be increased if Real
Goods' customer base continues to include a greater percentage of urban and
suburban dwellers. Real Goods believes that current trends reflect (i) increased
demands for its renewable energy products during the mild-weather months when
its customers are more likely to undertake construction and major home
improvement projects and (ii) increased demand for environmentally related gift
products, similar to that generally experienced by conventional retailers,
during the holiday season. (See "Real Goods Business - Real Goods' Markets".)

Backorders; Returns



                                       67
<PAGE>

    Backorders are considered common in certain other industries; however, in
the mail order industry, backorders can be symptoms of inefficiency, lack of
inventory or bad strategic planning since they create both additional costs and
risks of lost sales. The majority of Real Goods' backorders arise when (i)
vendors fail to deliver as promised, or (ii) sales of certain products are
higher than anticipated. At March 31, 1999, backorders were $236,000, which was
23% of that month's catalog sales. At March 31, 2000, backorders were $11,000,
which was 2% of that month's catalog sales. The main cause for the increase in
backorders at the end of fiscal 1999 was the significant increase in sales of
Y2K related products by substantially more than Real Goods anticipated. This
large backorder status had been significantly reduced by December 1999.

    Although Real Goods does have a 90-day return policy for products returned
by customers in their original condition, Real Goods has not historically
experienced substantial product returns for its catalog segment. For fiscal
2000, returns of catalog sales were 9.0% of gross catalog sales. This is an
increase over fiscal 1999 (6.6%) as a result of increasing the soft goods
portion of the product mix. Real Goods believes that the hard goods catalog
industry in general experiences returns of 5-6% and the soft goods catalog
industry experiences returns of 15-30%.

Competition

    Within the catalog market, Real Goods is very small compared to industry
leaders.  The market for environmentally related and healthy living products has
grown, and the number of both large and small catalog retailers carrying these
products has increased.  The same is true of Internet sales.  Real Goods has
also developed a small number of proprietary products. There can be no assurance
that Real Goods will ever sell material quantities of branded goods or
proprietary products. In the retail market, Real Goods is experimenting with
retail store formats and it expects to continue to refine its retail store
approach.

    In the renewable energy market, Real Goods operates in a niche presently too
technical and application specific to interest the larger catalogs.  Real Goods'
knowledge of its customer and awareness of vendor offerings as well as its
superior technical knowledge and experienced staff enable it to be a better
intermediary between suppliers and customers for its segment of the market than
larger catalogs. Real Goods believes that some Internet vendors without
technical support staff are underselling Real Goods' prices for common goods.
There can be no assurance that the resources or market positions of Real Goods'
competitors in this area will not change.

    In all three markets, Real Goods competes on the basis of price, selection
and service. Real Goods has continued to work to improve its pricing through
selective, focused buying and improved vendor discounts. In fiscal 2000, Real
Goods increased its presence at trade shows and plans to continue to improve its
product selection.

    Real Goods believes that its image is enhanced by the various
accomplishments that it has made in achieving its mission, including the opening
of its Solar Living Center demonstration site along with its ongoing educational
programs, the completion of the sale of the largest solar array in Latin
America, the tenth edition of the Solar Living Sourcebook, Real Goods' increased
presence on the Internet, the mission message in the mail order catalogs and
public relations efforts.

    Real Goods has a program in which participants pay a $50 fee to receive a
designated book, a newsletter with special pricing, closeout bargains and
substantial additional information, as well as a 5% discount on all purchases.
In most cases if customers have a large initial purchase, then will opt for the
program in order to take advantage of the discount on their order.  Real Goods'
program customers order much more frequently and have a higher average order
than Real Goods' other customers.  In fiscal 2000 the number of customers who
availed themselves of the discount program increased by 13% to approximately
62,000.

Regulation



                                       68
<PAGE>

    Although Real Goods believes that certain federal, state and local laws to
promote energy conservation may encourage the purchase of its products, Real
Goods also believes that most of its customers purchase its products for other
reasons.  Real Goods does not believe that it is subject to regulation other
than regulations applicable to catalog vendors of comparable products.   Real
Goods does not believe that the costs and effects of its own compliance with
federal, state and local environmental laws are likely to be material.  Real
Goods does not generally seek or obtain governmental approval for the products
it sells; rather, it believes that obtaining such approval is the responsibility
of its vendors or the products' manufacturers.  Real Goods has not, to its
knowledge, been named in any environmental cause of action relating to its
products or the sales thereof.

Employees

    As of November 15, 2000, Real Goods had the full time equivalent of 74
employees.  Of those employees, approximately  19 are employed at Real Goods'
retail stores, 4 are employed at Real Goods Renewables in Ukiah, approximately
31 are employed in Ukiah providing support to the catalog and corporate
functions, and 20 are employed at Santa Rosa, California at the Corporate
Headquarters.  As with many retailers, Real Goods increases its use of temporary
employees during its third fiscal quarter to meet the increased demands of the
holiday season.  Real Goods believes its use of temporary employees contributes
to its ability to control overhead costs.   Real Goods is not subject to any
collective bargaining agreements and believes its relationships with its
employees are good.

Trademarks

    Real Goods has registered the trademark "Real Goods" and has a license to
use the name "Earth Care" for recycled paper products but has discontinued that
product line. That license may be terminated under certain circumstances. Real
Goods has registered the name "Real Goods" in Japan. Real Goods does not believe
that any other patents, trademarks, licenses, franchises, concessions, royalty
agreements or labor contracts are material to its business.

Relationship with Whole Foods Market, Inc. and WholePeople.com

    In September 1999, Real Goods entered into a pair of agreements with Whole
Foods Market, Inc. Pursuant to one agreement, Whole Foods is to provide certain
marketing assistance to Real Goods. Pursuant to the other agreement, which was
assigned to Whole Foods' affiliate, WholePeople.com, Real Goods sold 800,000
shares of Real Goods' common stock to WholePeople.com for $3.6 million (see note
10 to Real Goods' financial statements for the fiscal year ended March 31,
2000). In June 2000, WholePeople.com issued an option to Gaiam for Gaiam to
purchase these 800,000 shares of Real Goods common stock.

    Concurrently, John Schaeffer, Chairman and Chief Executive Officer of Real
Goods, agreed to support a designee of WholePeople.com for election to Real
Goods' Board of Directors.

    Real Goods believes that it maintains adequate insurance for its real and
personal property.

                       CHANGES IN AND DISAGREEMENTS WITH
        REAL GOODS' ACCOUNTANTS ON ACCOUNTING AND FINANCIAL DISCLOSURE

    At the meeting of the Board of Directors of Real Goods on January 8, 2000,
it was determined to dismiss Deloitte and Touche LLP as the independent
accountants for Real Goods and to engage Moss Adams LLP. The report of Deloitte
and Touche LLP on the financial statements for each of the past two years did
not contain an adverse opinion or a disclaimer of opinion, nor was it qualified
or modified as to uncertainty of scope or accounting principles. The Audit
Committee concurred in the determination of Real Goods' Board of Directors.

                       COMPARISON OF SHAREHOLDER RIGHTS

     This section of the proxy statement/prospectus summarizes differences
between the Gaiam Class A common stock and Real Goods common stock. These
differences arise from differences between Colorado law and California law, and
between the corporate charters and bylaws of Gaiam and Real Goods.  Although
Gaiam and Real Goods believe that the following summary is a fair one, it should
be understood that it is a summary only and does not purport to be complete.
Real Goods shareholders should read the full text of each state's corporate
statutes and each companies' respective corporate charter and bylaws for a more
complete understanding of the differences between Gaiam Class A common stock and
Real Goods common stock. For information on how to obtain these documents, see
"Where You Can Find More Information" on page __.

     The rights of Real Goods' shareholders are governed by its articles of
incorporation, as amended, its bylaws, as amended, and the laws of the State of
California. The rights of Gaiam's shareholders are governed by its articles of
incorporation, as amended and restated, its bylaws, as amended and restated, and
Colorado law.  Upon completion of the merger, the Real Goods shareholders will
become Gaiam shareholders, and the Real Goods' shareholders' rights will be
governed by Gaiam's articles of incorporation, as amended, its bylaws, as
amended and restated, and Colorado law.

Authorized and Outstanding Capital Stock

Real Goods.  The authorized capital stock of Real Goods currently consists of
10,000,000 shares of common stock and 1,000,000 shares of preferred stock.  As
of November 15, 2000, there were outstanding 4,814,242 shares of Real Goods'
common stock held by 8,368 shareholders of record and options to purchase an
aggregate of 1,113,450 shares of Real Goods' common stock.  Holders of Real
Goods' common stock are entitled to one vote for each share held.

Gaiam.  The authorized capital stock of Gaiam is 250,000,000 shares, consisting
of 150,000,000 shares of Class A common stock, $.0001 par value per share,
50,000,000 shares of Class B common stock, $.0001 par value per share, and
50,000,000 shares of preferred stock, par value $.0001 per share.  As of
November 15, 2000, there were 5,462,780 shares of class A common stock
outstanding held by 1,031 shareholders of record, options to purchase an
aggregate of [908,050] shares, a warrant to purchase 24,000 shares and 5,400,000
shares of Class B common stock outstanding.  There were no shares of preferred
stock outstanding.  Holders of Gaiam's Class A common stock are entitled to one
vote for each share held and holders of Gaiam's Class B common stock are
entitled to ten votes for each share held, although pursuant to a voting
agreement between Gaiam and Mr. Rysavy, the Class B common stock is limited to
49% of the total votes and all shares over this limit are voted proportionately
with the Class A common stock. As a result of the voting agreement, holder of
Class A common stock will control the vote on all matters to be considered by
Gaiam's common stockholders.

Special Meeting of Shareholders

Real Goods.  Pursuant to Real Goods' bylaws, a special meeting of shareholders
may be called by the board of directors, the chairman of the board, the
president or by one or more shareholders holding shares in the aggregate
entitled to cast not less than 10% of the votes at that meeting.  The request
for special meeting shall be in writing, specifying the time of such meeting and
the general nature of the business proposed to be transacted, and shall be
delivered personally or sent by registered mail or by telegraphic or other
facsimile transmission to the chairman of the board, the president, any vice
president, or the secretary of the company.  The meeting will be held at the
time requested by the person or persons calling the meeting, not less than
thirty-five (35) nor more than sixty (60) days after the receipt of the request.


                                       73
<PAGE>

Gaiam.  A special meeting of shareholders may be called at any time by the
chairman of the board of directors, by the chief executive officer, by the
president, by resolution of the board of directors or by the holders of 10% of
the voting power of shares entitled to vote.  Notice of a special meeting shall
include a description of the purpose or purposes for which the meeting is
called.

Action by Written Consent in Lieu of Shareholders' Meeting

Real Goods.  Under California law, shareholders may execute an action by written
consent in lieu of a shareholder meeting.  Pursuant to Real Goods' bylaws, Real
Goods' shareholders may take action without a meeting by written consent if the
consent is signed by the holders of outstanding shares having not less than the
minimum number of votes that would be necessary to authorize or take that action
at a meeting at which all shares entitled to vote on that action were present
and voted.

Gaiam.  Under Colorado law, any action to be taken at a shareholders' meeting
may be taken without a meeting if all of the shareholders entitled to vote
thereon consent to such action in writing. Gaiam's bylaw provide that
shareholders may not take any action without a meeting, whether by written
consent or otherwise.  Because of the virtual impossibility of receiving written
consents from holders of 100% of the shares of a public company, Gaiam does not
believe its bylaw provision is a meaningful change from Colorado law.

Record Date for Determining Shareholders

Real Goods.  If the board of directors does not fix a record date, Real Goods'
bylaws provide that the record date for determining shareholders entitled to
notice of or to vote at a meeting of shareholders shall be at the close of
business on the business day next preceding the day on which notice is given or,
if notice is waived, at the close of business on the business day next preceding
the day on which the meeting is held.  The record date for determining
shareholders entitled to give consent to corporate action in writing without a
meeting, (i) when no prior action by the board of directors has been taken,
shall be the day on which the first written consent is given, or (ii) when prior
action of the board of directors has been taken, shall be at the close of
business on the day on which the board of directors adopts the resolution
relating to that action, or the 60th day before the date of such other action,
whichever is later.

Gaiam.  Pursuant to Gaiam's bylaws, its board of directors may fix in advance a
date as the record date for the purpose of determining shareholders entitled to
notice of or to vote at any meeting of shareholders or any adjournment thereof,
or shareholders entitled to receive payment of any dividend or in order to make
a determination of shareholders for any other proper purpose, such date in any
case to be not more than seventy (70) days before the meeting or action
requiring a determination of shareholders.  If no record date is fixed for the
determination of shareholders entitled to notice of or to vote at a meeting of
shareholders or shareholders entitled to receive payment of a dividend, the date
on which notice of the meeting is mailed or the date on which the resolution of
the board of directors declaring such dividend is adopted, as the case may be,
shall be the record date for such determination of shareholders.  When a
determination of shareholders entitled to vote at any meeting of shareholders
has been made, such determination shall apply to any adjournment thereof.  The
record date for determining shareholders entitled to demand a special meeting
shall be the date of the earliest of the demands pursuant to which the meeting
is called.

Notice Requirements of Shareholders' Meetings

Real Goods.  Pursuant to Real Goods' bylaws, all notices of shareholders'
meetings shall be sent or otherwise given either personally or by first-class
mail or telegraphic or other written communication,



                                       74
<PAGE>

charges prepaid, addressed to the shareholder. Notice shall be sent or otherwise
given not less than ten (10) nor more than sixty (60) days before the date of
the meeting. The notice shall specify the place, date and hour of the meeting
and (i) in the case of a special meeting, the general nature of the business to
be transacted, or (ii) in the case of the annual meeting, those matters which
the board of directors, at the time of giving the notice, intends to present for
action by the shareholders. The notice of any meeting at which directors are to
be elected shall include the name of any nominee or nominees whom, at the time
of the notice, management intends to present for election. If action is proposed
to be taken at any meeting for approval of (i) a contract or transaction in
which a director has a direct or indirect financial interest, (ii) an amendment
of the articles of incorporation, (iii) a reorganization of the corporation,
(iv) a voluntary dissolution of the corporation, or (v) a distribution in
dissolution other than in accordance with the rights of outstanding preferred
shares, the notice shall also state the general nature of that proposal.

Gaiam.  Pursuant to Gaiam's bylaws, notice stating the date, time and place of
the meeting shall be given no fewer than ten (10) and no more than sixty (60)
days before the date of the meeting, except that if the number of authorized
shares is to be increased, at least thirty (30) days' notice shall be given.
Notice shall be given personally or by mail, private carrier, telephone (if
reasonable under the circumstances), telegraph, teletype, electronically
transmitted facsimile or other form of wire or wireless communication by or at
the direction of the chief executive officer, the president, the secretary, or
the officer or other person calling the meeting to each shareholder of record
entitled to vote at such meeting.  If mailed and if in a comprehensible form,
such notice shall be deemed to be given and effective when deposited in the
United States mail, addressed to the shareholder at his or her address as it
appears in Gaiam's current record of shareholders, with postage prepaid. If
notice is given other than by mail, and provided that the notice is in
comprehensible form, the notice is given and effective on the date received by
the shareholder.

Shareholder Approval of Certain Business Combinations

Real Goods.  California law requires that , except in a short-form merger or the
merger of a corporation into its subsidiary in which it owns at least 90% of the
outstanding shares of each class, nonredeemable common shares of a constituent
corporation may be converted only into nonredeemable common shares of the
surviving corporation or a parent party if a constituent corporation or its
parent owns, directly or indirectly, shares of another constituent corporation
representing more than 50% of the voting power of the other corporation prior to
the merger unless all the shareholders of the class consent.

Gaiam.  Colorado law does not contain a provision limiting interested
shareholder business combinations.

Inspection of Shareholder List

Real Goods.  California law allows any shareholder to inspect and copy the
shareholder list for a purpose reasonably related to such person's interest as a
shareholder. California law provides, in addition, for an absolute right to
inspect and copy the corporation's shareholder list by persons holding an
aggregate of 5% or more of the corporation's voting shares, or shareholders
holding an aggregate of 1% or more of such shares who have made certain filings
with the SEC.  Real Goods' bylaws mirror the California statutory provisions
with respect to inspection of shareholder lists.

Gaiam.  Under Colorado law, a shareholder has the right to examine and copy the
books and records of a Colorado corporation during regular business hours at the
corporation's principal office if the shareholder gives the corporation five
business days written demand.  The demand must state the purpose of the
inspection.  An agent or attorney of the shareholder may also inspect the
records.  If the corporation


                                       75
<PAGE>

refuses to allow an inspection, a Colorado court may order an inspection. A
shareholder may also inspect a shareholder list in connection with a shareholder
meeting.

Dividends and Repurchases of Shares

Real Goods.  Under California law, a corporation may not make any distribution
to its shareholders unless either:  (1) the corporation's retained earnings
immediately prior to the proposed distribution equal or exceed the amount of the
proposed distribution; or (2) immediately after giving effect to such
distribution, the corporation's assets exclusive of goodwill, capitalized
research and development expenses and deferred charges, would be at least equal
to 1 1/4 times its liabilities and the corporation's current assets would be at
least equal to its current liabilities or 1 1/4 times its current liabilities if
the average pre-tax and pre-interest expense earnings for the preceding two
fiscal years were less than the average interest expense for such years.

Gaiam.  Under Colorado law, directors may, subject to any restrictions in the
corporation's articles of incorporation, declare and pay dividends so long as,
after giving effect to the distribution (1) the corporation may pay its debts as
they become due and (2) the total assets of the corporation would not be less
than the sum of the total liabilities plus the amount needed to satisfy
preferential rights of shareholders with superior rights upon a dissolution of
the corporation.

Procedures to Nominate Directors

Real Goods.  The Real Goods' bylaws require that nominations of persons for
election to the board of directors may be made at a meeting of shareholders by
or at the direction of the board of directors or by any shareholder of the
corporation entitled to vote in the election of directors at the meeting.  Such
nominations, other than those made by or at the direction of the board of
directors, shall be made pursuant to timely notice in writing to the secretary
of the corporation.

Gaiam.  Nominations of persons for election as directors of Gaiam may be made at
a meeting of shareholders (a) by or at the direction of the board of directors,
(b) by any nominating committee or persons appointed by the board of directors
or (c) by any shareholders of Gaiam entitled to vote for the election of
directors at the meeting who complies with the applicable notice procedures
provided in Gaiam's bylaws. Such nominations, other than those made by or at the
direction of the board of directors or any nominating committee or persons
appointed by the board, shall be made pursuant to timely notice in writing to
the secretary of Gaiam. To be timely, a shareholder's notice shall be delivered
to or mailed and received at Gaiam's principal executive office (i) in the case
of the annual meeting of Gaiam's shareholders (other than an annual meeting in
which the date of the meeting has been changed by more than 30 days from the
prior year), not less than 45 nor more than 70 days before the date on which
Gaiam first mailed its proxy materials for the prior year's annual meeting of
shareholders, or (ii) in the case of any other meeting of Gaiam's shareholders,
not less than 50 nor more than 75 days prior to the meeting; provided, however,
that in the event that less than 60 days' notice or prior public disclosure of
the date of such other meeting is given or made to shareholders, notice by the
shareholder to be timely must be so received not later than the close of
business on the tenth day following the day on which such notice of the date of
such other meeting was mailed or such public disclosure was made, whichever
first occurs.

Cumulative Voting Rights

Real Goods. California corporate law provides for cumulative voting for
directors.  Real Goods' bylaws provide that no shareholder shall be entitled to
cumulate votes (i.e., cast for any one or more candidates a number of votes
greater than the number of the shareholder's shares) unless the candidates'
names have



                                       76
<PAGE>

been placed in nomination prior to commencement of the voting and a
shareholder has given notice prior to commencement of the voting of the
shareholder's intention to cumulate votes.  If any shareholder has given such a
notice, then every shareholder entitled to vote may cumulate votes for
candidates in nomination and give one candidate a number of votes equal to the
number of directors to be elected multiplied by the number of votes to which
that shareholder's shares are entitled, or distribute the shareholder's votes on
the same principle among any or all of the candidates, as the shareholder thinks
fit.

Gaiam. A Colorado corporation may have cumulative voting for directors unless
expressly prohibited by the articles of incorporation. Gaiam has expressly
prohibited cumulative voting in its articles of incorporation.

Number of Directors

Real Goods.  The Real Goods' bylaws provide that the Real Goods board of
directors may not have less than four nor more than seven directors. The exact
number of directors is four until changed by resolution, approved by the Board
of Directors or the shareholders.  The indefinite number of directors may be
changed, or a definite number fixed without provision for an indefinite number,
by a duly adopted amendment to the articles of incorporation or by an amendment
to the bylaws approved by the shareholders; provided, however, that an amendment
reducing the number or the minimum number of directors to a number less than
five cannot be adopted if the votes cast against its adoption at a meeting of
the shareholders, or the shares not consenting in the case of action by written
consent, are equal to more than sixteen and two-thirds (16 2/3%) of the
outstanding shares entitled to vote.  No amendment may change the stated maximum
number of authorized directors to a number greater than two times the stated
minimum number of directors minus one.

Gaiam.  Gaiam's bylaws provide that the number of directors shall be set by
resolution of the board of directors.  There are currently six members of
Gaiam's board of directors.

Classified Board of Directors

Real Goods.  A classified board is one for which a certain number, but not all,
of the directors are elected on a rotating basis each year.  Under California
law, a corporation that is not a listed corporation cannot provide for a
classified board.  Real Goods is not a listed corporation under California law.

Gaiam. Under Colorado law, the articles of incorporation may provide for
staggering the terms of directors into two or three groups for terms of two or
three years.  The Gaiam articles of incorporation do not presently provide for a
classified board of directors.

Removal of Directors

Real Goods.  Under California law, any director or the entire board of directors
may be removed without cause with the approval of a majority of the outstanding
shares entitled to vote thereon.  However, no individual director may be removed
(unless the entire board is removed) if the number of votes cast against such
removal would be sufficient to elect the director under cumulative voting,
whether or not the corporation's articles of incorporation or bylaws do not
otherwise provide for cumulative voting.  A corporation's board of directors may
remove for cause by declaring vacant the office of a director who has been (i)
declared of unsound mind by an order of court or (ii) convicted of a felony.

Gaiam.  Under Colorado law, a member of the Board may be removed by the
shareholders with or without cause, if the vote in favor of removal exceeds the
vote opposed.  Gaiam's bylaws provide that the


                                       77
<PAGE>

shareholders may remove the entire board of directors or any individual director
without assignment of cause by the vote of the majority of the shares entitled
to vote in an election of directors.

Board of Directors Vacancies

Real Goods.  Unless otherwise provided in a corporation's articles of
incorporation or bylaws, under California law, any vacancy on a board of
directors, other than one created by removal of a director, may be filled by
approval of the remainder of the corporation's board of directors.  Even if the
number of remaining directors is less than a quorum, a vacancy may be filled by
the unanimous written consent of the directors then in office or by the
affirmative vote of a majority of the directors at a meeting held pursuant to
notice or waivers of notice or by a sole remaining director.  Unless the
articles of incorporation or a bylaw adopted by the shareholders provide that
the board may fill vacancies occurring in the board by reason of the removal of
directors, such vacancies may be filled only with the approval of a majority of
the outstanding shares entitled to vote thereon.  Real Goods' bylaws provide
that vacancies on Real Goods' board, except for a vacancy created by the removal
of a director, may be filled by a majority of the remaining directors, even if
less than a quorum, or by a sole remaining director. A vacancy created by the
removal of a director by the shareholders or by court order may be filled only
by a vote of the shareholders at a duly held meeting at which a quorum is
present.

Gaiam.  Under Colorado law, unless otherwise provided in the articles of
incorporation, vacancies on the board of directors, including vacancies
resulting from an increase in the number of members of the board of directors,
may be filled by a majority of the shareholders, the board of directors or, if
the remaining directors are less than a quorum, by the affirmative vote of a
majority of all directors remaining.  If the vacant office is elected by a
voting class, the directors remaining of that class or the holders of shares of
that class may fill the vacancy.  Pursuant to Gaiam's bylaws, any vacancy on its
board of directors may be filled by the affirmative vote of a majority of the
remaining members of the board of directors even if less than a quorum is
remaining in office.  A director elected to fill a vacancy shall be elected for
the unexpired term of his predecessor in office.  Any directorship to be filled
by reason of an increase in the number of directors shall be filled by the
affirmative vote of a majority of the directors then in office or by an election
at an annual meeting or special meeting of shareholders called for that purpose.
A director elected to fill a position resulting from an increase in the number
of directors shall hold office until the next annual meeting of shareholders and
until his or her successor has been elected and qualified.

Amendment of Articles of Incorporation and Bylaws

Real Goods.  California law provides that, unless otherwise stated in a
corporation's articles of incorporation, an amendment to the articles of
incorporation requires the approval of the corporation's board of directors and
the affirmative vote of a majority of the outstanding shares entitled to vote on
those shares.  Unless otherwise provided in the articles of incorporation, any
provision in the articles of incorporation which requires a greater vote than
required by law cannot be amended or repealed except by the greater vote.
California law provides that when the rights of a class of shares will be
affected by an amendment, the holders of those shares may vote as a class even
if the shares are non-voting shares.  In addition, when only one or more series
in a class of shares, and not the entire class, will be adversely affected by an
amendment, only the affected shares may vote as a class. Section 211 of the
California corporate law provides that, unless the board of directors is
prohibited by the articles of incorporation, the bylaws, or Section 212 of the
California corporate law, the board or a majority of the outstanding shares
entitled to vote may amend the bylaws.  Real Goods' bylaws may be amended or
repealed by the vote or written consent of holders of a majority of the
outstanding shares entitled to vote.  In addition, the Real


                                       78
<PAGE>

Goods' board of directors may adopt, amend or repeal the bylaws other than those
changing the authorized number of directors.

Gaiam.  Under Colorado law, each holder of shares of an affected class of stock,
voting in separate voting groups, is entitled to vote on any amendment to the
Articles of Incorporation that would (i) increase or decrease the aggregate
number of authorized shares of the class; (ii) effect an exchange or
reclassification of all or part of the shares of the class into shares of
another class; (iii) effect an exchange or reclassification, or create the right
of exchange, of all or part of the shares of another class into shares of the
class; (iv) change the designation, preferences, limitations or relative rights
of all or part of the shares of the class; (v) change the shares of all or part
of the class into a different number of shares of the same class; (vi) create a
new class of shares having rights or preferences with respect to distributions
or dissolution that are prior, superior or substantially equal to the shares of
the class; (vii) increase the rights, preferences, or number of authorized
shares of any class that, after giving effect to the amendment, have rights or
preferences with respect to distributions or to dissolutions that are prior,
superior, or substantially equal to the shares of the class; (viii) limit or
deny an existing preemptive right of all or part of the shares of the class; or
(ix) cancel or otherwise affect rights to distributions or dividends that have
accumulated but have not yet been declared on all or part of the shares of the
class.  Pursuant to Gaiam's bylaws, the Board of Directors may amend, supplement
or repeal the bylaws or adopt new bylaws, subject to repeal or change by action
of the shareholders.

Quorum

Real Goods.  Pursuant to Real Goods' bylaws, the presence in person or by proxy
of the holders of a majority of the shares entitled to vote at any meeting of
shareholders shall constitute a quorum for the transaction of business.   The
shareholders present at a duly called or held meeting at which a quorum is
present may continue to do business until adjournment, notwithstanding the
withdrawal of enough shareholders to leave less than a quorum, if any action
taken (other than adjournment) is approved by at least a majority of the shares
required to constitute a quorum.

Gaiam.  Pursuant to Colorado law and Gaiam's bylaws, a majority of the shares
entitled to vote, present in person or represented by proxy shall constitute a
quorum at any meeting of shareholders, but a quorum shall not consist of fewer
than one-third of the votes entitled to be cast.

Vote Required for Merger

Real Goods. California law requires a majority of the outstanding shares of each
class of shares affected that is entitled to vote to approve a merger, except
that no shareholder vote is required of a corporation that will be the surviving
corporation in the merger as long as the shareholders of the corporation own,
immediately after the merger, more than five-sixths of the voting power of the
surviving corporation.  If a corporation has two classes of common shares that
differ only as to voting rights, the shares will vote as a single class.
Similar voting requirements apply for share exchanges.  In addition, California
law further requires the affirmative vote of a majority of the outstanding
shares entitled to vote on the merger if:  (1) the surviving corporation's
articles of incorporation will be amended and would otherwise require
shareholder approval; or (2) shareholders of the surviving corporation will
receive shares of a non-California corporation or shares of the surviving
corporation having different rights, preferences, privileges or restrictions
than the shares surrendered.

Gaiam.  Under Colorado law, no vote of the shareholders of a surviving
corporation is required to approve a merger or consolidation if the plan does
not amend the articles of incorporation, each shareholder of the surviving
corporation will hold the same number of shares with identical rights after


                                       79
<PAGE>

the merger, the number of voting shares outstanding after the merger plus the
number of shares issuable as a result of the merger will not exceed by 20% the
total number of shares before the merger and the number of participating shares
(i.e. shares that entitle their holders to participate without limitation in
distributions) outstanding after the merger plus the number of participating
shares issuable as a result of the merger will not exceed by 20% the total
number of participating shares before the merger. No vote of the shareholders of
a subsidiary is required to approve a merger or consolidation of a 90% or
greater parent and the subsidiary and a vote of the parent in this circumstance
is not required if the conditions described in the first sentence are met.
Because Gaiam was incorporated in Colorado prior to the adoption of the new
Colorado Business Corporation Act, transitional rules under Colorado law provide
that fundamental corporate transactions, such as mergers, consolidations, sales
of all or substantially all of the corporation's assets and dissolutions,
require the approval of a majority of the board of directors and approval of the
holders of two-thirds of the outstanding shares of Gaiam's common stock.

Dissolution Rights

Real Goods.  Under California law, shareholders holding 50% or more of the total
voting power may authorize a corporation's dissolution, with or without the
approval of the corporation's board of directors.

Gaiam.  Under Colorado law, the proposal to dissolve shall be approved by each
voting group entitled to vote separately on the proposal by a majority of all
the votes entitled to be cast on the proposal by that voting group.

Dissenters' Rights

Real Goods. California law provides that if the approval of the outstanding
shares of a corporation is required for a reorganization under specific
provisions of California law, each shareholder of the corporation entitled to
vote on the transaction who did not vote in favor of the transaction may require
the corporation to purchase for cash, at the fair market value, any "dissenting
shares" owned by the shareholder.  Shares listed on the New York Stock Exchange,
the American Stock Exchange or the Nasdaq National Market System generally do
not have these appraisal rights unless the holders of at least 5% of the class
of outstanding shares demand the right, or the corporation or any law restricts
the transfer of the shares. The fair market value will be determined as of the
day before the first announcement of the terms of the proposed reorganization,
excluding any appreciation or depreciation as a result of the proposed action.
Colorado law specifies a procedure whereby the shareholder must perfect his or
her dissenters' rights.


Gaiam.  Shareholders of Colorado corporations are entitled to exercise certain
dissenters' rights in the event of a merger, share exchange, sale, lease,
exchange or any other disposition of all or substantially all of the property
and assets of a corporation.  Shareholders are also permitted to dissent if
dissenters' rights for a corporate action are provided for in the corporation's
bylaws or a directors resolution.  Shareholders of a Colorado corporation may
dissent in the case of a reverse stock split that reduces the number of shares
owned by the shareholder to a fraction of a share or to scrip if the fraction or
scrip is to be acquired for cash or the scrip will be voided.  Under Colorado
law, dissenting shareholders are entitled to object to the proposed corporate
action and obtain the payment of the fair value of the shares of the corporation
owned by the shareholder. Colorado law specifies a procedure whereby the
shareholder must perfect his or her dissenters' rights.

Fiduciary Duty of Board of Directors



                                       80
<PAGE>

Real Goods.  California law provides that a director shall perform the duties of
a director, including duties as a member of any committee of the board upon
which the director may serve, in good faith, in a manner such director believes
to be in the best interests of the corporation and its shareholders and with
such care, including reasonable inquiry, as an ordinarily prudent person in a
like position would use under similar circumstances.  A director shall be
entitled to rely on information, opinions, reports or statements, including
financial statements and other financial data prepared or presented by officers
or employees of the corporation, legal counsel, accountants or a committee of
the board of directors.

Gaiam. Colorado law provides that directors must discharge duties in good faith,
with the care of an ordinary prudent person and in a manner he or she believes
to be in the best interests of the corporation.  A director may rely on
information, opinions, reports or statements prepared or presented by officers
or employees of the corporation, legal counsel, accountants or a committee of
the board of directors.

Limitations on Directors' Liability

Real Goods.  Under California law, the liability of a director for monetary
damages may be limited in a corporation's articles by including a provision
eliminating or limiting the personal liability of a director for monetary
damages in an action brought by or in the right of the corporation for breach of
a director's duties to the corporation and its shareholders, provided that (A)
such a provision may not eliminate or limit the liability of directors (i) for
acts or omissions that involve intentional misconduct or a knowing and culpable
violation of law, (ii) for acts or omissions that a director believes to be
contrary to the best interests of the corporation or its shareholders or that
involve the absence of good faith on the part of the director, (iii) for any
transaction from which a director derived an improper personal benefit, (iv) for
acts or omissions that show a reckless disregard for the director's duty to the
corporation or its shareholders in circumstances in which the director was
aware, or should have been aware, in the ordinary course of performing a
director's duties, of a risk of serious injury to the corporation or its
shareholders, (v) for acts or omissions that constitute an unexcused pattern of
inattention that amounts to an abdication of the director's duty to the
corporation or its shareholders, (vi) under Section 310 of the California
corporate law, or (vii) under Section 316 of the California corporate law, (B)
no such provision shall eliminate or limit the liability of a director for any
act or omission occurring prior to the date when the provision becomes
effective, and (C) no such provision shall eliminate or limit the liability of
an officer for any act or omission as an officer, notwithstanding that the
officer is also a director or that his or her actions, if negligent or improper,
have been ratified by the directors.

Gaiam.  Under Colorado law, if so provided in the articles of incorporation, the
corporation shall eliminate or limit the personal liability of a director to the
corporation or to its shareholders for monetary damages for breach of fiduciary
duty as a director; except that any such provision shall not eliminate or limit
the liability of a director to the corporation or to its shareholders for
monetary damages for any breach of the director's duty of loyalty to the
corporation or to its shareholders, acts or omissions not in good faith or which
involve intentional misconduct or a knowing violation of law, acts for unlawful
distributions, or any transaction from which the director directly or indirectly
derived an improper personal benefit.  No such provision shall eliminate or
limit the liability of a director to the corporation or to its shareholders for
monetary damages for any act or omission occurring before the date when such
provisions becomes effective.

    No director shall be personally liable for any injury to person or property
arising out of a tort committed by an employee unless such director or officer
was personally involved in the situation giving rise to the litigation or unless
such director committed a criminal offense in connection with such situation.
This provision does not restrict the corporation's right to eliminate or limit
the personal liability


                                       81
<PAGE>

of a director to the corporation or to its shareholders for monetary damages for
breach of fiduciary duty as a director.

Indemnification

Real Goods.  Under California law, a corporation has the power to indemnify any
person who was or is a party or is threatened to be made a party to any
proceeding (other than an action by or in the right of the corporation to
procure a judgment in its favor) by reason of the fact that the person is or was
an agent of the corporation, against expenses, judgments, fines, settlement, and
other amounts actually and reasonably incurred in connection with the proceeding
if that person acted in good faith and in a manner the person reasonably
believed to be in the best interests of the corporation and, in the case of a
criminal proceeding, had no reasonable cause to believe the conduct of the
person was unlawful.  The termination of any proceeding by judgment, order,
settlement, conviction, or upon a plea of nolo contendere or its equivalent
shall not, of itself, create a presumption that the person did not act in good
faith and in a manner which the person reasonably believed to be in the best
interests of the corporation or that the person had reasonable cause to believe
that the person's conduct was unlawful.  A corporation shall have power to
indemnify any person who was or is a party or is threatened to be made a party
to any threatened, pending, or completed action by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that the
person is or was an agent of the corporation, against expenses actually and
reasonably incurred by that person in connection with the defense or settlement
of the action if the person acted in good faith, in a manner the person believed
to be in the best interests of the corporation and its shareholders.

     Real Goods' bylaws provide that the corporation will indemnify each of its
directors, officers, employees or other agents of the corporation  to the
fullest extent permitted by the California corporate law.  In addition, the
corporation:  (a) is authorized to provide indemnification of agents in excess
of that expressly permitted by Section 317 of the California corporate law for
those agents of the corporation for breach of duty to the corporation and its
shareholders; provided, however, that the corporation is not authorized to
provide indemnification of any agent for any acts or omissions or transactions
from which a director may not be relieved of liability as set forth in the
exception to Section 204(a)(10) of the California corporate law or as to the
circumstances in which indemnity is expressly prohibited by Section 317 of the
California corporate law; and (b) shall have the power to purchase and maintain
insurance on behalf of any agent of the corporation against any liability
asserted against or incurred by the agent in such capacity or arising out of the
agent's status as such, whether or not the corporation would have the power to
indemnify the agent against such liability under the provisions of Section 317
of the California corporate law, and shall have the power to advance the
expenses reasonably expected to be incurred by such agent in defending any such
proceeding upon receipt of the undertaking required by Section 317(f) of the
California corporate law.

    Real Goods has entered into separate indemnification agreements with each of
its directors and officers pursuant to which Real Goods has agreed to indemnify
such director or officer against claims or liabilities incurred in his position
as such.

Gaiam.  Under Colorado law, a corporation may indemnify a director, officer,
other employee or agent who is made party to a proceeding because the person was
or is a director if the person acted in good faith and reasonably believed and
acted in the best interest of the corporation (or not opposed to the best
interest of the corporation when not acting in his or her official capacity).
In the case of a criminal proceeding, a person may be indemnified if he or she
had no reasonable cause to believe that his or her conduct was unlawful. Unless
limited by the corporation's articles of incorporation, a Colorado corporation
must indemnify the reasonable expenses of a person who is wholly successful in
the defense



                                       82
<PAGE>

of a proceeding to which the person was a party because he or she was a
director, officer, other employee or agent. A corporation may advance expenses
to a director, officer, other employee or agent in a proceeding if the person
seeking indemnification furnishes the corporation with a written statement of
his or her good faith belief that he or she acted in good faith, agrees to repay
expenses if it is determined he or she did not meet the standard of conduct and
if it is determined that the facts known would not preclude indemnification.
Colorado law prohibits indemnification in connection with a derivative action if
the person was adjudged liable to the corporation or in connection with a
proceeding charging the director derived an improper personal benefit in which
the person was adjudged liable on the basis that he or she derived an improper
personal benefit.

     A determination that the director, officer, other employee or agent has met
the required standard of conduct, and that indemnification therefore is proper,
must be made (i) by a majority vote of disinterested directors and only the
disinterested directors may be counted for the quorum, (ii) by a committee of
such directors designated by majority vote of such directors, even though less
than a quorum, (iii) if there are no such directors, or if such directors so
direct, by independent legal counsel in a written opinion, or (iv) by the
shareholders.  A corporation may also purchase insurance on behalf of a
director, officer, other employee or agent.

     Gaiam's bylaws provide that Gaiam will indemnify against liability, to the
fullest extent authorized by the Colorado law, as the same exists or may
hereafter be amended (but, in the case of any such amendment, only to the extent
that such amendment permits Gaiam to provide broader indemnification rights than
permitted prior thereto), incurred in any proceeding by an individual made a
party to a proceeding because he is or was a director of Gaiam or any subsidiary
of Gaiam if: (a) he conducted himself in good faith; (b) he reasonably believed:
(i) in the case of conduct in his official capacity with Gaiam, that his conduct
was in the Gaiam's best interests; or (ii) that in all other cases, that his
conduct was at least not opposed to the Gaiam's  best interests; and (c) in the
case of any criminal proceeding, he had no reasonable cause to believe his
conduct was unlawful.  Gaiam may not indemnify a person either (a) in connection
with a proceeding by or in the right of Gaiam in which such person was adjudged
liable to Gaiam; or (b) in connection with any proceeding charging improper
personal benefit to such person, whether or not involving action in his official
capacity, in which he was adjudged liable on the basis that personal benefit was
improperly received by him.

Interested Director Transactions

California and Colorado law both provide that certain contracts or transactions
in which one or more of a corporation's directors has an interest are not
necessarily void or voidable simply because of the interest or because the
director is present at or participates in the meeting of the board or committee
which authorizes the contract or transaction.  Both California and Colorado law
provide that such interested director transactions are not void or voidable as
long as:  (a) either an informed, independent majority of the shareholders or of
the board of directors or a committee thereof approve any such contract or
transaction after full disclosure of the material facts, or (b) the contract or
transaction must have been fair as to the corporation at the time it was
approved.

as set forth in their report thereon included therein and incorporated herein by
reference. Such consolidated financial statements are incorporated herein by
reference in reliance upon such report given on the authority of such firm as

audited by Moss Adams LLP, independent auditors, as stated in their reports and
have been given upon their authority as experts in accounting and auditing. The
financial statements of Real Goods Trading Corporation as of March 31, 1999 and

                         FUTURE SHAREHOLDER PROPOSALS

    If the merger takes place, Real Goods will have no more annual meetings.  If
the merger does not take place, any Real Goods shareholder who wished to submit
a shareholder proposal for possible inclusion in the proxy statement and proxy
for Real Goods' 2001 annual meeting of shareholders must do so within a
reasonable time before Real Goods prints and mails its proxy materials for such
meeting.  Any such proposal should be sent to the attention of the Secretary of
Real Goods at 3440 Airway Drive, Santa Rosa, California 95403.  A shareholder
proposal being submitted outside the processes of Rule 14a-8 promulgated under
the Securities Exchange Act of 1934 will be considered untimely if not received
within a reasonable time before Real Goods mails its proxy material for the 2001
annual meeting.  If Real Goods receives notice of such proposal after such time,
each proxy that Real Goods receives will confer upon it the discretionary
authority to vote on the proposal in the manner the proxies deem appropriate.

                         REAL GOODS TRADING CORPORATION
                         NOTES TO FINANCIAL STATEMENTS

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION - Real Goods Trading Corporation (the "Company") was organized on
July 1, 1990 and sells primarily environmentally related, "healthy living" and
renewable energy products through mail order catalogs, four retail stores, the
Internet, and direct sales from its renewable energy department.

USE OF ESTIMATES - The preparation 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 disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amount of revenues and expenses during
the reporting period.  Actual results could differ from those estimates.

CHANGE IN PRESENTATION  - Included in net sales for fiscal years 2000 and 1999
are shipping and handling fees collected from customers of $1,388,000 and
$1,516,000, respectively. Included in cost of sales for fiscal years 2000 and
1999 are freight out expenses of $1,118,000 and $1,152,000 respectively.
Previously, these amounts were presented as a net amount in selling, general and
administrative expenses.  Such sales and cost of sales have been reclassified
into net sales and cost of sales for the periods presented because management
believes this more accurately represents the Company's true sales and cost of
sales amounts.

CASH AND MARKETABLE SECURITIES - Marketable securities are classified as
available-for-sale and are available to support current operations or to take
advantage of other investment opportunities.  Marketable securities are stated
at estimated fair value based upon market quotes and consist of bonds,
commercial paper and Federal agency securities.  As of March 31, 2000, fair
value approximated cost and no unrealized gain or loss was included in retained
earnings.  Realized gains and losses are included in other income.  Interest
earned is included in interest income. The Company has deposits in money funds
in excess of federally insured levels.  These deposits are placed with quality
financial institutions.

INVENTORIES are stated at the lower of cost (first-in/first-out  method) or
market.  Inventories include expenses associated with acquiring the inventory.

DEFERRED CATALOG COSTS - The Company capitalizes the direct cost of producing
and distributing its mail order catalogs.  Deferred catalog costs are amortized
based on the estimated sales lives of the catalogs, generally eighteen weeks.

PROPERTY, EQUIPMENT AND IMPROVEMENTS are stated at cost.  Depreciation is
computed using the straight-line method over the estimated useful lives of the
assets, which range from 5 to 40 years.

INTERNET SITE COSTS are capitalized in accordance with AICPA Statement of
Position (SOP) 98-1 and EITF 00-2.

PROPERTY HELD FOR SALE  - The building and land which were the former Snow Belt
Store are currently held for sale.

NOTE RECEIVABLE - AFFILIATE - The note receivable represents net funds advanced
to the Real Goods Institute for Solar Living ("ISL") and bears interest at 5.25%
per year. Interest only is payable until the ISL becomes self-funding.



                                      F-8
<PAGE>

PRE-OPENING COSTS for retail stores are expensed as incurred.

INCOME TAXES - The Company accounts for its income taxes using an asset and
liability approach that requires the recognition of deferred tax assets and
liabilities for the expected future tax consequences of events that have been
recognized in the Company's financial statements or tax returns.  In estimating
future tax consequences, the Company generally considers all expected future
events other than changes in tax laws.

LOSS PER SHARE - Basic loss per share is computed by dividing net loss by the
weighted average number of shares outstanding for the period.  Diluted loss per
share reflects the potential dilution that could occur if contracts to issue
common stock were exercised or converted to common stock.  Dilutive stock
options were not included for the fiscal years ended March 31, 2000 and 1999, as
the Company incurred a net loss in each year and the effect would be
antidilutive.

RECLASSIFICATION - The 1999 financial statements have been reclassified in order
to conform to the March 31, 2000 presentation.

ESTIMATED FAIR VALUE OF FINANCIAL INSTRUMENTS - Statement of Financial
Accounting Standard ("SFAS") No. 107, "Disclosures About Fair Value of Financial
Instruments" requires disclosure of the estimated fair value of financial
instruments.  The carrying values of cash, marketable securities, accounts
receivable, accounts payable, and long-term debt approximates their estimated
fair values.

STOCK-BASED COMPENSATION - The Company accounts for stock-based awards to
employees using the intrinsic value method in accordance with Accounting
Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees".

COMPREHENSIVE INCOME - Comprehensive loss and net loss are the same.

losses available for carryforward of approximately $1,950,000 and $1,536,000 for
federal and state purposes, respectively.  The federal net operating loss and
$430,000 of the state net operating losses will expire in 2013 through 2020.

intends to use various tax planning strategies to fully utilize the loss
carryforwards prior to expiration.

9.  SHAREOWNER AGREEMENTS

The Chairman of the Board, founder and largest shareowner has a renewable one-
year employment agreement with the Company which provides for an annual salary
of $125,000.  As of April 1, 2000 the Chairman voluntarily agreed to a reduction
in such salary to $110,000 on a month to month basis.

The Company also has a split dollar life insurance agreement with this
individual whereby the Company pays the premiums.  The Company has been granted
a security interest in the cash value and death benefit of the policy, and
certain shares of the Company stock owned by the Chairman of the Board have been
pledged as additional collateral during the period in which the premiums exceed
the cash surrender value.  The net cash surrender value at March 31, 2000 was
$215,000 and is included in other assets.

10.  SHAREOWNERS' EQUITY

On August 11, 1997 the Company commenced a direct public offering of up to
1,000,000 shares of newly issued stock and 300,000 shares offered by a selling

Through March 31, 1999, the Company had issued 676,641 new shares of common
stock, generating gross proceeds of $3,620,000, and had incurred costs of
$697,000 related to the direct public offering.

In August 1998, the Company was authorized to repurchase up to $100,000 of
common stock in open market and private transactions.  In fiscal 1999, 3,900
shares were repurchased for $14,850.  In fiscal 2000, 800 shares were

Additional Stock Plan Information

As discussed in Note 1, the Company continues to account for its stock-based
awards using the intrinsic value method in accordance with Accounting Principles
Board No.25, "Accounting for Stock Issued to Employees" and its related
interpretations.  Accordingly, no compensation expense has been recognized in
the financial statements for employee stock arrangements in fiscal 1999 or 1998.

Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation", (SFAS 123) requires the disclosure  of pro forma net income and
earnings per share had the Company adopted the fair value method as of the
beginning of fiscal 1996.  Under SFAS 123, the fair value of stock-based awards
to employees is calculated through the use of the option pricing models, even
though such models were developed to estimate the fair value of freely tradable,
fully transferable options without vesting restrictions, which significantly
differ from the Company's stock option awards.  These models also require
subjective assumptions, including future stock price volatility and expected
time to exercise, which greatly affect the calculated values.  The Company's
calculations were made using the Black-Scholes option pricing model with the
following weighted average assumptions: Expected life, 120 months following
vesting in fiscal 2000 and fiscal 1999, stock volatility, 32% in fiscal 1999 and
55% in fiscal 2000; risk free interest rate 5.50% in fiscal 1999 and 5.65 % in
fiscal 2000; and no dividends during the expected term.  The Company's
calculations are based on a multiple option valuation approach and forfeitures
are calculated at a 50% rate, based on the Company's historical experience. If
the computed fair values of the fiscal 2000 and fiscal 1999 awards had been
amortized to expense over the vesting period of the awards, pro forma net loss
would have been $569,000 or $.14 per share in fiscal 1999, and the pro forma net

The Company has three divisions (Catalog, Retail and Renewables), all of which
sell products purchased from other suppliers for sale directly to customers. The
customer bases of all three divisions overlap to some extent, and the purchases
and delivery processes to customers overlap as well.

Each of the three divisions qualifies as a reportable segment because each is
more than 10% of the combined revenue of all operating segments. Contribution is
defined as net sales less cost of goods sold and direct expenses. Financial
information for the Company's business segments was as follows:

NOTE 1 - BASIS OF PRESENTATION

The accompanying unaudited condensed financial statements have been prepared
from the records of the Company and, in the opinion of management, include all
adjustments (consisting of only normal recurring accruals) necessary to present
fairly the financial position as of September 23, 2000 and the interim results
of operations and cash flows for the three and six months ended September 23,
2000 and September 25, 1999. The balance sheet as of March 31, 2000 was derived
from the Company's audited financial statements included in the Company's Annual

followed by the Company are described in Note 1 to the audited financial
statements for the fiscal year ended March 31, 2000 included in the Company's
fiscal 2000 Annual Report to Shareowners. Certain information and footnote
disclosures normally included in financial statements prepared in accordance
with generally accepted accounting principles have been condensed or omitted for
purposes of the condensed financial statements. The condensed financial
statements should be read in conjunction with the audited financial statements,
including notes thereto, for the year ended March 31, 2000. The results of
operations for the three and six month periods herein presented are not
necessarily indicative of the results to be expected for the full year.

NOTE 2 - PRESENTATION OF SHIPPING AND HANDLING FEES

Included in net sales for the three and six month periods ended September 23,
2000 and September 25, 1999 are shipping and handling fees collected from
customers of $226,000 and $438,000 in fiscal 2001 and $259,000 and $536,000 in
fiscal 2000, respectively. Included in cost of sales for the three and six month

of $225,000 and $424,000 in fiscal 2001 and $184,000 and $432,000 in fiscal
2000, respectively.

NOTE 3 - LINE OF CREDIT

The Company has a line of credit agreement for $1,500,000 with National Bank of
the Redwoods (the "Bank") which expires on February 28, 2001. Borrowings bear
interest at 1.5% over the prime rate, payable in monthly installments. The line
of credit agreement contains restrictive covenants including debt to net worth,
current ratios, restrictions on capital expenditures, and prohibitions on
payment of cash dividends without the Bank's approval. The line is
collateralized by substantially all of the Company's assets, including
inventory, accounts receivable and mailing lists as well as a key person life
insurance policy on the life of the Company's Chairman and largest shareowner.
As of September 23, 2000, no amounts were outstanding on the Company's line of
credit.

NOTE 4 - SHAREOWNERS' EQUITY

In two separate resolutions in August 1998 and April 2000, the Board of
Directors authorized the Company to purchase up to a total of $200,000 of common
stock in open market and private transactions. During the first six months of
fiscal 2001 the Company repurchased 67,500 shares at an average cost of $2.17

NOTE 5 - SEGMENT INFORMATION

The Company has four divisions (Catalog, Internet, Retail and Renewables), all
of which sell products purchased from other suppliers directly to customers. The
customer bases of all four divisions overlap to some extent, and the purchase
and delivery processes to customers overlap as well.

Each of the four divisions qualifies as a reportable segment because each is
more than 10% of the combined revenue of all operating segments.  Financial
information for the Company's business segments for the six months ended
September 23, 2000 and September 25, 1999 was as follows:

         Notes to Interim Condensed Consolidated Financial Statements

                              September 30, 2000

1.  Interim Condensed Consolidated Financial Statements

    Organization and Nature of Operations
    -------------------------------------

    Gaiam, Inc. (the "Company") was incorporated under the laws of the State of
Colorado on July 7, 1988. Gaiam is a lifestyle company providing information,
goods and services to customers who value the environment, personal development
and healthy lifestyles.

    The accompanying consolidated financial statements include the accounts of
the Company, its subsidiaries and partnerships in which ownership is greater
than 50% and considered to be under the control of the Company. All material
intercompany accounts and transaction balances have been eliminated in
consolidation.

    Preparation of Interim Condensed Consolidated Financial Statements
    ------------------------------------------------------------------

    The interim condensed consolidated financial statements included herein
have been prepared by the management of Gaiam, Inc. pursuant to the rules and
regulations of the United States Securities and Exchange Commission, and, in the
opinion of management, contain all adjustments (consisting of only normal
recurring adjustments) necessary to present fairly the Company's consolidated
financial position as of September 30, 2000 and the interim results of
operations and cash flows for the three and nine months ended September 30, 2000
and 1999. These interim statements have not been audited. The balance sheet as
of December 31, 1999 was derived from the Company's audited consolidated
financial statements included in the Company's annual report on Form 10-K.

    Certain information and footnote disclosures normally included in
consolidated financial statements prepared in accordance with generally accepted
accounting principals have been condensed or omitted pursuant to such rules and
regulations. Accounting policies followed by the Company are described in Note 1
to the audited financial statements for the fiscal year ended December 31, 1999
included in the Company's annual report on Form 10- K. The consolidated
financial statements contained herein should be read in conjunction with the
audited financial statements, including the notes thereto, for the year ended
December 31, 1999.

    The consolidated financial position, results of operations and cash flows
for the interim periods disclosed within this report are not necessarily
indicative of future financial results.

  Use of Estimates
  ----------------

     The preparation of consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets, liabilities,
revenues and expenses and disclosure of contingent assets and liabilities at the
date of the consolidated financial statements. Actual results could differ from
those estimates.

  Recently Issued Accounting Standards Not Yet Adopted
  ----------------------------------------------------

     On June 1998, the FASB issued SFAS No. 133, Accounting for Derivative
Instruments and Hedging Activities. SFAS No. 133 is effective for fiscal years
beginning after June 15, 2000. SFAS No. 133 requires that all derivative
instruments be recorded on the balance sheet as either an asset or liability
measured at their fair value. In June 1999, the FASB issued Statement of
Financial Accounting Standard No. 137, "Accounting for Derivative Instruments
and Hedging Activities - Deferrral of the Effective   Date of FASB No. 133"
delaying the effective date of SFAS No. 133. In June 2000, the FASB issued
Statement of Financial Accounting Standard No. 138, "Accounting for Certain
Derivative Instruments and Certain Hedging Activities" amending certain
accounting and reporting standards of SFAS No. 133. SFAS No. 133, as amended, is
effective for the Company's fiscal 2001 financial statements. As the Company is
currently not a party to any derivative instruments and does not anticipate
becoming a party to any derivative instruments, management does not currently
expect the adoption of SFAS No. 133, as amended, to have a material impact on
the Company's consolidated financial statements.

     In May 2000, the Emerging Issues Task Force issued EITF 00-14, "Accounting
for Certain Sales Incentives." Under the provisions of EITF 00- 14, for sales
incentives that will not result in a loss on the sale of a product or service, a
vendor should recognize the "cost" of the sales incentive at the latter of the
date the related revenue is recorded by the vendor or the date the sales
incentive is offered. A reduction to or refund of the selling price of the
product or service resulting from any cash sales incentive should be classified
as a reduction of revenue. Costs of free products or services delivered at the
time of sale should be classified as an expense. The EITF should be applied in
the fourth quarter of the fiscal year beginning after December 15, 1999.
Management does not expect the adoption of EITF 00-14 to have a material impact
on the Company's consolidated financial statements.

    Recently Issued Accounting Standards Not Yet Adopted (continued)
    ----------------------------------------------------------------

    In July 2000, the Emerging Issues Task Force issued EITF 00-10, "Accounting
for Shipping and Handling Fees and Costs."  Under the provisions of EITF 00-10,
amounts billed to a customer in a sale transaction related to shipping and
handling represent revenues earned for the goods provided and should be
classified as sales revenues.  However, the related shipping and handling costs
may not be netted against sales revenue.  In September 2000, the EITF made an
addition to the final consensus reached at the July 2000 meeting requiring the
dollar amount and income statement classification of any significant shipping
and handling costs be disclosed pursuant to APB Opinion No. 22, "Disclosure of
Accounting Policies."  The Company currently, and historically, has classified
shipping and handling fees earned as revenue, and shipping and handling costs
within "selling and operating" expenses.  Therefore, management believes the
adoption of EITF 00-10 will not have an impact on the Consolidated Statements of
Income.

2.  Mergers and Acquisitions
    ------------------------

    On June 30, 2000, Gaiam, Inc. and Wholepeople.com, Inc. ("Amrion")
contributed their Internet properties (the "Contribution") into a newly formed
company subsequently renamed Gaiam.com, Inc. The Contribution was made pursuant
to the terms of a contribution agreement among Gaiam, Amrion, and certain
related parties. In exchange for the contributed Internet properties, Gaiam
received 50.1% of Gaiam.com's common stock and Amrion received the remaining
49.9% of Gaiam.com's common stock. Gaiam.com, which will continue its Internet
e-commerce business, and will be consolidated by Gaiam with Gaiam's other
operations. In exchange for their share of Gaiam.com, Amrion contributed $3.0
million in cash, a $3.0 million short-term note and other Internet assets. On
September 15, 2000, Gaiam, Inc. filed a report on Form 8-K/A reporting this
transaction.

    On October 13, 2000, Gaiam, Inc. entered into a Merger Agreement with Real
Goods Trading Corporation, Inc. pursuant to which Gaiam will acquire 100% of the
Real Goods issued and outstanding common stock in exchange for shares of Gaiam's
Class A common stock. The merger is subject to approval by the Real Goods
shareholders and certain other conditions described in the Merger Agreement. The
merger is expected to close in January 2001. If the merger is approved, the Real
Goods shareholders will receive one share of Gaiam Class A common stock in
exchange for each ten shares of Real Goods common stock. In

    Mergers and Acquisitions (continued)
    ------------------------------------

addition, the Real Goods shareholders will receive $1 in gift certificates for
Gaiam products for each share owned, up to $100 per person.

3.  Line of Credit
    --------------

    In May 2000, the Company consolidated its line of credit agreements with
Wells Fargo Bank into one agreement. The new credit agreement, which extends
through January 31, 2002, permits borrowings up to $5 million based upon the
collateral value of Gaiam's accounts receivable and inventory held for resale.
Borrowings under this agreement bear interest at the prime rate, which was 9.5%
at September 30, 2000. These borrowings are secured by a pledge of Gaiam's
assets and contain various financial covenants, including prohibiting the
payment of cash dividends to its shareholders and requiring maintenance of
certain financial ratios.

4.  Redeemable Preferred Stock in Subsidiary
    ----------------------------------------

    On June 19, 2000, Gaiam, Inc. sold 6,000 shares of Redeemble Class A
preferred stock in its Internet subsidiary, Gaiam.com, Inc., at a price of
$1,000 per share for an aggregate price of $6,000,000. This stock is redeemable
upon the consummation of any offering by Gaiam.com of its equity securities to
the public pursuant to an effective registration statement with the Securities
and Exchange Commission. The Company has determined that it is more appropriate
to classify this redeemable Class A preferred stock as a component of minority
interest as opposed to stockholders' equity and has reflected that
reclassification in this September 30, 2000 balance sheet.

5.  Stockholders' Equity
    --------------------

    During the second quarter of 2000, Gaiam issued 21,243 shares of Class A
common stock for an acquisition, and the e-commerce rights and purchase option
in an organic clothing manufacturer.

6.  Earnings per Share
    ------------------

    Basic earnings per share excludes any dilutive effects of options, warrants,
and dilutive securities. Basic earnings per share is computed using the weighted
average number of common shares outstanding during the period. Diluted earnings
per share is computed using the weighted average number of common and common
stock equivalent shares outstanding during the period. Common equivalent shares
are excluded from the computation if their effect is antidilutive. All earnings
per share amounts for all period have been presented and conform to the
Statement No. 128 requirements.

7.  Segment Information
    -------------------

    The Company has two business segments: Direct to Consumer and Business to
Business; both of which sell products, services and information produced or
purchased from other suppliers. Although the customer bases do not overlap to
any significant extent, the production,


                                      F-28
<PAGE>

purchase and delivery processes overlap in some areas. The Company does not
accumulate the balance sheet by segment for purposes of management review.

    Each of the two segments qualifies as such because each is more than 10%
of combined revenue. Contribution margin is defined as net sales, less cost of
goods

                                MERGER AGREEMENT

     MERGER AGREEMENT dated as of October 13, 2000 between GAIAM, INC., a
Colorado corporation ("Gaiam"), and REAL GOODS TRADING CORPORATION, a California
corporation ("Real Goods"). Certain capitalized terms used in this Agreement
shall have the meanings assigned to them in Annex I.

     WHEREAS, the Boards of Directors of each of Real Goods and Gaiam have
determined to engage in the transactions contemplated by this Agreement,
pursuant to which, among other things, at the Effective Time, (i) a wholly owned
Subsidiary to be formed by Gaiam ("Gaiam Subsidiary") shall merge with and into
Real Goods (the "Merger"), and (ii) each share of common stock, without par
value, of Real Goods ("Real Goods Common Shares") (except for Real Goods Common
Shares owned by Real Goods and Real Goods Common Shares as to which appraisal
rights have been perfected) shall be converted, as set forth in this Agreement,
into the right to receive, in exchange for ten such Real Goods Common Shares,
one share of the class A common stock of Gaiam (the "Gaiam Class A");

     WHEREAS, the Board of Directors of Gaiam has approved this Agreement and
the Merger contemplated by this Agreement;

     WHEREAS, the Board of Directors of Real Goods has approved this Agreement
and the Merger contemplated by this Agreement and resolved to recommend that
shareholders of Real Goods approve and adopt this Agreement and the Merger;

     WHEREAS, for federal income tax purposes, it is intended that the Merger
shall qualify as a tax free reorganization within the meaning of Section 368 of
the Internal Revenue Code of 1986, as amended (the "Code");

     WHEREAS, for accounting purposes, it is intended that the Merger shall be
accounted for under the purchase method of accounting; and

     WHEREAS, Real Goods and Gaiam desire to make certain representations,
warranties, covenants and agreements in connection with the transactions
contemplated by this Agreement and also to prescribe certain conditions to the
transactions contemplated by this Agreement; and

     WHEREAS, as inducements to Real Goods and Gaiam entering into this
Agreement and incurring the obligations set forth herein, and contemporaneously
with the execution and delivery of this Agreement, certain shareholders of Real
Goods have agreed to enter into separate Voting Agreements pursuant to which,
among other things, such shareholders will vote all of their Real Goods Common
Shares in favor of this Agreement and the Merger;

     NOW, THEREFORE, in consideration of the foregoing and the warranties,
covenants and agreements contained herein, the parties hereto agree as follows:

                                   ARTICLE 1
                                   The Merger

     Section 1.1.  Gaiam Subsidiary; Merger

     (a)  At the Effective Time, Gaiam Subsidiary shall be merged (the "Merger")
with and into Real Goods in accordance with the California General Corporation
Law (the "California Law"), whereupon the separate existence of Gaiam Subsidiary
shall cease, and Real Goods shall be the surviving corporation (the "Surviving
Corporation").

     (b)  The Closing shall take place at the offices of Bartlit Beck Herman
Palenchar & Scott in Denver, Colorado at 10:00 a.m. on the second business day
following the fulfillment or waiver of each of the conditions precedent to the
Merger set forth in Article 7, or at such other place, time and date as the
parties hereto may agree.

     (c)  At the Closing, upon fulfillment or waiver of the conditions precedent
to the Merger set forth in Article 7, the parties shall cause a Certificate of
Merger to be filed with the Secretary of State of the State of California and a
tax clearance certificate, in such form as required by, and duly executed in
accordance with, the relevant provisions of the California Law using the
procedures permitted in Section 103 of the California Law. The Merger shall
become effective at such time as the Certificate of Merger is duly filed with
the Secretary of State of the State of California or at such later time as Gaiam
and Real Goods agree to specify in the Certificate of Merger (the "Effective
Time").

     (d)  From and after the Effective Time, the Surviving Corporation shall
possess all the rights, privileges, powers and franchises and be subject to all
of the restrictions, disabilities and duties of Real Goods, all as provided
under California Law.

     (e)  The Surviving Corporation may, at any time after the Effective Time,
take any action (including the execution and delivery of any document) in the
name and on behalf of Real Goods or Gaiam Subsidiary in order to carry out and
effectuate the transactions contemplated by this Agreement.

     (f)  Gaiam hereby represents that its Board of Directors has (x)
unanimously determined that this Agreement and the Merger are fair to and in the
best interests of Gaiam's shareholders and (y) approved this Agreement and the
Merger, which approval satisfies in full the requirements of the California Law
that the Agreement be approved by Gaiam's Board of Directors. Real Goods hereby
represents that its Board of Directors has (i) unanimously determined that this
Agreement and the Merger are fair to and in the best interests of Real Goods
shareholders, (ii) approved this Agreement and the Merger, and (iii) resolved to
recommend approval and adoption of this Agreement and the Merger by its
shareholders.

     Section 1.2.  Conversion of Shares.  At the Effective Time:

     (a)  each Real Goods Common Share held by Real Goods as treasury stock
shall be canceled and no payment shall be made with respect thereto; and

     (b)  each ten Real Goods Common Shares outstanding immediately prior to the
Effective Time shall (except as otherwise provided in Section 1.2(a) or as
provided in Section 1.4 with respect to Real Goods Common Shares as to which
appraisal rights have been perfected) be cancelled and extinguished and be
converted into and become a right to receive one (the "Exchange Ratio") share of
Gaiam Class A in exchange for such Real Goods Common Shares; provided that the
Exchange Ratio may be further adjusted subject to the terms of Sections 1.3(k),
8.1(l) or 8.1(m).  In addition to the shares of Gaiam Class

                                      A-7
<PAGE>

A, following the Closing Gaiam shall provide to each Real Goods shareholder a
gift certificate to purchase Gaiam's products. Each shareholder of Real Goods
shall receive a $1 gift certificate for each Real Goods Common Share exchanged
pursuant to this Section 1.2(b), up to a maximum of $100 for such shareholder.
Such gift certificate along with the shares of Gaiam Class A issued to Real
Goods shareholders shall be referred to as the "Merger Consideration"; and

     (c)   Each issued and outstanding share of the common stock of Gaiam
Subsidiary shall be converted into one fully paid and nonassessable share of
common stock of the Surviving Corporation.

     Section 1.3.  Exchange of Certificates

     (a)   Exchange Agent.  From and after the Effective Time, from time to time
           --------------
Gaiam shall make available to American Securities Transfer & Trust, Inc. or such
other bank or trust company designated by Gaiam (the "Exchange Agent"), for the
benefit of the holders of Real Goods Common Shares, for exchange in accordance
with this Article 1 through the Exchange Agent, (i) certificates evidencing a
sufficient number of shares of Gaiam Class A and (ii) a sufficient number of
gift certificates described in Section 1.2, all issuable to holders of Real
Goods Common Shares, to satisfy the requirements set forth in Section 1.2
relating to Merger Consideration (such shares of Gaiam Class A, gift
certificates and any cash deposited with the Exchange Agent relating to
Additional Payments, if any, being hereinafter referred to as the "Exchange
Fund").  As promptly as practicable after the Effective Time, Gaiam shall cause
the Exchange Agent to deliver the Merger Consideration and Additional Payments,
if any, contemplated to be issued pursuant to Section 1.2 out of the Exchange
Fund in accordance with the procedures specified in this Section 1.3.  Except as
contemplated by Section 1.3(g) hereof, the Exchange Fund shall not be used for
any other purpose.

     (b)   Exchange Procedures.  Promptly after the Effective Time, Gaiam shall
           -------------------
cause the Exchange Agent to mail to each record holder of a certificate or
certificates which immediately prior to the Effective Time represented
outstanding Real Goods Common Shares (the "Certificates") (i) a letter of
transmittal (which shall be in customary form and 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 Exchange Agent) and (ii)
instructions for use in effecting the surrender of the Certificates in exchange
for the Merger Consideration.

     (c)   Exchange of Certificates.  Upon surrender to the Exchange Agent of a
           ------------------------
Certificate for cancellation, together with a properly completed letter of
transmittal, duly executed and completed in accordance with the instructions
thereto, and such other documents as may be reasonably required pursuant to such
instructions, the holder of such Certificate shall be entitled to receive in
exchange therefor a certificate representing that number of whole shares of
Gaiam Class A, if any, constituting the Merger Consideration to which such
holder is entitled pursuant to this Article 1 (including any dividends or other
distributions to which such holder is entitled pursuant to Section 1.3(d)
(together, the "Additional Payments")), and the Certificate so surrendered shall
forthwith be canceled.  In the event of a transfer of ownership of Real Goods
Common Shares which is not registered in the transfer records of Real Goods, the
applicable Merger Consideration and Additional Payments, if any, may be issued
to a transferee if the Certificate representing such Real Goods Common Shares is
presented to the Exchange Agent, accompanied by all documents required to
evidence and effect such transfer and by evidence that any applicable stock
transfer taxes have been paid.  Until surrendered as contemplated by this
Section 1.3, each Certificate shall be deemed at all times after the Effective
Time to represent only the right to receive upon such surrender the applicable
Merger Consideration with respect to the Real Goods Common Shares formerly
represented thereby and Additional Payments, if any.

                                      A-8
<PAGE>

     (d)  Distributions with Respect to Unsurrendered Certificates.  No
          --------------------------------------------------------
dividends or other distributions declared or made after the Effective Time with
respect to Gaiam Class A with a record date after the Effective Time shall be
paid to the holder of any unsurrendered Certificate with respect to Gaiam Class
A, until the holder of such Certificate shall surrender such Certificate.
Subject to the effect of escheat, tax or other applicable Laws, following
surrender of any such Certificate, there shall be paid to the holder of the
certificates representing whole shares of Gaiam Class A issued in exchange
therefor, without interest, (i) promptly, the amount of dividends or other
distributions with a record date after the Effective Time and theretofore paid
with respect to such whole shares of Gaiam Class A, and (ii) at the appropriate
payment date, the amount of dividends or other distributions, with a record date
after the Effective Time but prior to surrender and a payment date occurring
after surrender, payable with respect to such whole shares of Gaiam Class A.
After the Effective Time, each outstanding Certificate which theretofore
represented Real Goods Common Shares shall, until surrendered for exchange in
accordance with this Section 1.3, be deemed for all purposes to evidence the
right to receive the Merger Consideration into which the Real Goods Common
Shares (which, prior to the Effective Time, were represented thereby) shall have
been so converted.

     (e)  No Further Rights in Real Goods Common Shares.  At the Effective Time
          ---------------------------------------------
all outstanding Real Goods Common Shares, by virtue of the Merger and without
any action on the part of the holders thereof, shall no longer be outstanding
and shall be canceled and retired and shall cease to exist, and each holder of a
Certificate shall thereafter cease to have any rights with respect to such Real
Goods Common Shares, except the right to receive the Merger Consideration for
such Real Goods Common Shares.  All Gaiam Class A and gift certificates
constituting Merger Consideration issued upon conversion of the Real Goods
Common Shares in accordance with the terms hereof shall be deemed to be validly
issued, fully paid and nonassessable and all such cash paid pursuant to Section
1.3(d) or (f) shall be deemed to have been issued or paid, as the case may be,
in full satisfaction of all rights pertaining to such Real Goods Common Shares.

     (f)  No Fractional Shares.  No fractional shares of Gaiam Class A shall be
          --------------------
issued in the Merger.  In lieu of any such fractional shares, each holder of
Real Goods Common Shares who holds a number of Real Goods Common Shares that is
not a whole multiple of 10, will be entitled to receive, in addition to the gift
certificates referred to in Section 1.2(b), $1 in additional gift certificates
for each $1 (rounded up to the nearest whole dollar) in market value of
fractional Gaiam Class A shares to which such holder would otherwise have been
entitled had fractional shares been issued (based on the closing price of a
share of Gaiam Class A on the Nasdaq National Market on the date on which the
Effective Time occurs as reported in The Wall Street Journal). For example, if
the closing price of Gaiam Class A is $20, a holder of 25 Real Goods Common
Shares will receive 2 shares of Gaiam Class A based upon the Exchange Ratio and
a $10 gift certificate in exchange for the remaining 5 Real Goods Common Shares
and in lieu of fractional shares (in addition to the $25 gift certificate such
holder will also receive as part of the Merger Consideration). The parties
acknowledge that payment of the gift certificates in lieu of issuing fractional
shares was not separately bargained for consideration but merely represents a
mechanical rounding for purposes of simplifying the corporate and accounting
complexities which would otherwise be caused by the issuance of fractional
shares.

     (g)  Termination of Exchange Fund.  Any portion of the Exchange Fund which
          ----------------------------
remains undistributed to the holders of Real Goods Common Shares for one year
after the Effective Time shall be delivered to Gaiam (who shall thereafter act
as Exchange Agent), upon demand, and any holders of Real Goods Common Shares who
have not theretofore complied with this Article 1 shall thereafter look only to
Gaiam for the applicable Merger Consideration and any Additional Payments to
which they are entitled.  To the extent permitted by applicable law, any portion
of the Exchange Fund remaining unclaimed by holders of Real Goods Common Shares
as of a date which is immediately prior to such time

                                      A-9
<PAGE>

as such amounts would otherwise escheat to or become property of any government
entity shall, on the first anniversary of the Effective Date and to the extent
permitted by applicable law, become the property of Gaiam free and clear of any
claims or interest of any person previously entitled thereto.

     (h)  No Liability.  None of the Exchange Agent or Gaiam shall be liable to
          ------------
any holder of Certificates for any shares of Gaiam Class A (or dividends or
distributions with respect thereto), or cash delivered to a public official
pursuant to any abandoned property, escheat or similar law.

     (i)  Withholding Rights.  Gaiam shall be entitled to deduct and withhold
          ------------------
from the consideration otherwise payable pursuant to this Agreement to any
holder of Certificates such amounts as it is required to deduct and withhold
with respect to the making of such payment under the Code, or any provision of
state, local or foreign tax law.  To the extent that amounts are so withheld by
Gaiam, such withheld amounts shall be treated for all purposes of this Agreement
as having been paid to the holder of the Certificates in respect of which such
deduction and withholding was made by Gaiam.

     (j)  Lost Certificates.  If any Certificate shall have been lost, stolen or
          -----------------
destroyed, upon the making of an affidavit of that fact by the person claiming
such Certificate to be lost, stolen or destroyed and, if required by Gaiam, the
posting by such person of a bond, in such reasonable amount as Gaiam may direct,
as indemnity against any claim that may be made against it with respect to such
Certificate, the Exchange Agent will issue in exchange for such lost, stolen or

or Gaiam Class A, as applicable), extraordinary dividend, reorganization,
recapitalization or any other like change with respect to Real Goods Common
Shares or Gaiam Class A occurring after the date hereof and prior to the
Effective Time.  References to the Exchange Ratio elsewhere in this Agreement
shall be deemed to refer to the Exchange Ratio as it may have been adjusted
pursuant to this Section 1.3(k).

     (l)  Stock Transfer Books.  At the Effective Time, the stock transfer books
          --------------------
of Real Goods shall be closed and there shall be no further registration of
transfers of Real Goods Common Shares thereafter on the records of Real Goods.

Exchange Agent pursuant to this Section 1.3 to pay for Real Goods Common Shares
for which appraisal rights have been perfected shall be returned to Gaiam upon
its demand.

     (n)  Reasonable Actions.  Real Goods and Gaiam shall use all reasonable
          ------------------
efforts to take all such action as may be necessary or appropriate in order to
effectuate the Merger as promptly as possible.  If, at any time after the
Effective Time, any further action is necessary or desirable to carry out the
purposes of this Agreement and to vest Gaiam with full right, title and
possession to all assets, property, rights, privileges, immunities, powers and
franchises of Real Goods, the officers and directors of Gaiam are fully
authorized in the name of Real Goods or otherwise to take, and shall take, all
such action.

<PAGE>

the Merger or consented thereto in writing and who has demanded appraisal for
such Real Goods Common Shares in accordance with California Law ("Dissenting
Shares") shall not be converted into a right to receive the Merger
Consideration, unless such holder fails to perfect or withdraws or otherwise
loses its right to appraisal or it is determined that such holder does not have
appraisal rights in accordance with California Law. If after the Effective Time
such holder fails to perfect or withdraws or loses its right to appraisal, or if
it is determined that such holder does not have an appraisal right, such Real
Goods Common Shares shall be treated as if they had been converted as of the
Effective Time into a right to receive in exchange for each Real Goods Common
Share the Merger Consideration.

     Section 1.5.  Stock Options.  At the Effective Time, any options to
purchase and Real Goods Common Shares or any other securities of Real Goods
shall be canceled and extinguished and of no further force or effect and no

Real Goods stock option plans as in effect on the date of this Agreement.   Any
stock option plan or other plan pursuant to which Real Goods Common Shares or
any other options, warrants or convertible securities exercisable for or
convertible into securities of Real Goods may be issued or granted shall also be
canceled and extinguished and of no further force or effect.

     Section 1.6.  Transfer Taxes, etc.   Except as set forth in Section 1.3,
the Surviving Corporation shall bear and be responsible for the payment of all
transfer, stamp, documentary, sales, use, registration and other similar Taxes

Person responsible for paying such Taxes) incurred in connection with the
exchange of Real Goods Common Shares for the Merger Consideration.

duly incorporated, validly existing and in good standing under the laws of the
State of California, and has all corporate powers and all material governmental
licenses, authorizations, consents and approvals required to carry on its
business as now conducted. Real Goods is duly qualified to do business as a
foreign corporation and is in good standing in each jurisdiction where the
character of the property owned or leased by it or the nature of its activities

performance by Real Goods of this Agreement and the consummation by Real Goods
of the transactions contemplated by this Agreement are within Real Goods'
corporate powers and, except for any required approval by Real Goods'
shareholders in connection with the consummation of the Merger, have been duly
authorized by all necessary corporate action. This Agreement constitutes a valid
and binding agreement of Real Goods, enforceable against Real Goods in
accordance with its terms, subject to applicable bankruptcy, insolvency or other
similar laws relating to or affecting the enforcement of creditors' rights
generally and to legal principles of general applicability governing the
application and availability of equitable remedies.

merger and a tax clearance certificate in accordance with the California Law;
(b) compliance with any applicable requirements of the Securities Act, the
Exchange Act or any Blue Sky Laws; and (c) compliance with those Laws,
Regulations and Orders noncompliance with which would not reasonably be expected
to have a Real Goods Material Adverse Effect or to prevent, impair or result in
significant delay of the consummation of the Merger.  Without limiting the first
sentence of this Section 3.3, the execution, delivery and performance by Real
Goods of this Agreement and the consummation of the transactions contemplated by
this Agreement by Real Goods require no action or waiting period by or in

Disclosure Schedule, the execution, delivery and performance by Real Goods of

3.3,  (i) constitute a default under or give rise to (A) a right of termination,
cancellation, acceleration, amendment or modification with respect to Real Goods
or any of its Subsidiaries, (B) a loss of any benefit to which Real Goods or any
of its Subsidiaries is entitled or (C) an increase in the obligations of Real

Effect, (ii) result in the creation or imposition of any material Lien (other

Order or Permit applicable to Real Goods, its Subsidiaries and their respective
assets except for any such matters that would not reasonably be expected,
individually or in the aggregate, to have a Real Goods Material Adverse Effect.

the Disclosure Schedule and the transactions contemplated by this Agreement,

Goods, (b) grants a right of first refusal or other such similar right upon the
sale of Real Goods Common Shares, or (c) restricts or affects the voting rights
of Real Goods Common Shares.  There is no liability for dividends declared or

corporation or other legal entity duly incorporated or organized, validly
existing and in good standing under the laws of its jurisdiction of
incorporation or organization, has all corporate or entity powers and all
governmental licenses, authorizations, consents and approvals required to carry
on its business as now conducted, except to the extent the failure to have such

each jurisdiction where the character of the property owned or leased by it or
the nature of its activities makes such qualification necessary, except for
those jurisdictions where failure to be so qualified would not, individually or
in the aggregate, have a Real Goods Material Adverse Effect.

     (b)  The only Subsidiaries of Real Goods are those listed in Section 3.6
                                                                  -----------

shares of capital stock of, or other equity interests in, each of the
Subsidiaries of Real Goods and such shares and interests have been duly
authorized and are validly issued, and, with respect to capital stock, are fully
paid and nonassessable, and were not issued in violation of any preemptive or
similar rights of any past or present equity holder of such Subsidiary.

     Section 3.7.  SEC Filings. Real Goods has filed all required forms, reports
and documents with the SEC since January 1, 1997, including, (i) its Annual
Report on Form 10-K for the fiscal year ended March 31, 2000 (the "Real Goods
10-K"), (ii) the proxy statement relating to Real Goods' 1999 annual meeting of
shareholders, (iii) its Quarterly Report on Form 10-Q for the fiscal quarter
ended June 24, 2000 (the "Real Goods 10-Q") and, (iv) all other reports or
registration statements filed by Real Goods with the SEC since January 1, 1997
(collectively, the "Real Goods SEC Reports") with the SEC, all of which complied
when filed in all material respects with all applicable requirements of the
Securities Act and the Exchange Act.  The audited consolidated financial
statements and unaudited consolidated interim financial statements of Real Goods
and its subsidiaries included or incorporated by reference in such Real Goods
SEC Reports were prepared in accordance with generally accepted accounting
principles applied on a consistent basis during the periods involved (except as
may be indicated in the notes thereto) and present fairly, in all material
respects, the financial position and results of operations and cash flows of

                                      A-13
<PAGE>

Real Goods and its Subsidiaries on a consolidated basis at the respective dates
and for the respective periods indicated (and in the case of all such financial
statements that are interim financial statements, contain all adjustments so to
present fairly).  Except to the extent that information contained in any Real
Goods SEC Report was revised or superseded by a later filed Real Goods SEC
Report, none of the Real Goods SEC Reports contained any untrue statement of a
material fact or omitted to state any 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.  Real Goods has
provided to Gaiam copies of all other correspondence sent to or received from
the SEC by Real Goods and its Subsidiaries since January 1, 1997 (other than
cover letters).

     Section 3.8.   Consolidated Financial Statements. Real Goods has provided
to Gaiam true and complete copies of the unaudited consolidated balance sheet of
Real Goods at June 24, 2000 (the "Real Goods Balance Sheet") and the unaudited
consolidated statements of income, shareholders' equity and cash flow of Real
Goods for the period from March 31 through June 24, 2000 (collectively, the
"Real Goods Most Recent Financials"). The Real Goods Most Recent Financials
fairly present, in all material respects, the financial position of Real Goods
at June 24, 2000, and the results of operations of Real Goods for the period
then ended, and have been prepared in accordance with generally accepted
accounting principles applied on a consistent basis, except that such financial
statements will not include any footnote disclosures that might otherwise be
required to be included by generally accepted accounting principles, and shall
also be subject to normal non-recurring year-end audit adjustments.  The Real
Goods Balance Sheet reflects all liabilities of Real Goods, whether absolute,
accrued or contingent, as of the date thereof of the type required to be
reflected or disclosed on a balance sheet prepared in accordance with generally
accepted accounting principles (applied in a manner consistent with the notes of
the financial statements included in Real Goods 10-K).

     Section 3.9.   Disclosure Documents. None of the information supplied or to
be supplied by or on behalf of Real Goods for inclusion or incorporation by
reference in the registration statement to be filed with the SEC by Gaiam in
connection with the issuance of shares of Gaiam Class A in the Merger (the
"Registration Statement") will, at the time the Registration Statement becomes
effective under the Securities Act, contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading.  None of the information supplied or to be
supplied by or on behalf of Real Goods for inclusion or incorporation by
reference in the proxy statement/prospectus, in definitive form, relating to the
Real Goods Shareholder Meeting (as hereinafter defined), or in the related proxy
and notice of meeting, or soliciting material used in connection therewith
(referred to herein collectively as the "Proxy Statement") will, at the dates
mailed to shareholders and at the time of the Real Goods Shareholder Meeting,
contain any untrue statement of a material fact or omit to state any material
fact required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they are made, not
misleading.  Real Goods will promptly inform Gaiam of the happening of any event
prior to the Effective Time which would render such information regarding Real
Goods incorrect in any material respect or require the amendment of the Proxy
Statement. The Proxy Statement (except for information relating solely to Gaiam
and Gaiam Subsidiary) will comply as to form in all material respects with the
provisions of the Securities Act and the Exchange Act.

     Section 3.10.  Absence of Certain Changes.  Except for this Agreement and

     (b)  any declaration, setting aside or payment of any dividend or other
distribution with respect to any shares of capital stock of Real Goods, or any

respect of such exercise) or other acquisition by Real Goods or any of its
Subsidiaries of any outstanding shares of capital stock or other securities of,
or other ownership interests in, Real Goods or any of its Subsidiaries;

     (c)  any amendment of any material term of any outstanding security of Real
Goods or any of its Subsidiaries other than amendments to the terms of the
existing credit facilities of Real Goods or its Subsidiaries or borrowings under
such facilities;

any Lien (other than Permitted Encumbrances) on any material asset of Real Goods
or any of its Subsidiaries other than in the ordinary course of business
consistent with past practices;

     (f)  any making of any loan, advance or capital contribution to or
investment in any Person other than loans, advances or capital contributions to
or investments in wholly-owned Subsidiaries made in the ordinary course of

     (h)  any transaction or commitment made, or any contract or agreement

relinquishment by Real Goods or any of its Subsidiaries of any contract or other
right, in either case, material to Real Goods and its Subsidiaries taken as a
whole, other than transactions and commitments in the ordinary course of
business consistent with past practice and those contemplated by this Agreement;

     (i)  any change in any method of accounting or accounting practice by Real
Goods or any of its Subsidiaries, whether or not any such change is required by
reason of a concurrent change in generally accepted accounting principles;

     (j)  any (i) grant of any severance or termination pay to any director,
officer or employee of Real Goods or any of its Subsidiaries, (ii) entering into
of any employment, deferred compensation or other similar agreement (or any
amendment to any such existing agreement) with any director, officer or employee
of Real Goods or any of its Subsidiaries, (iii) increase in benefits payable
under any existing severance or termination pay policies or employment
agreements or (iv) increase in compensation, bonus or other benefits payable to

<PAGE>

except for such grants, payments, increases or changes in the ordinary course of
business consistent with past practice; or

     (k)  any labor dispute, other than routine individual grievances, or any
activity or proceeding by a labor union or representative thereof to organize
any employees of Real Goods or any of its Subsidiaries, which employees were not
subject to a collective bargaining agreement at the date of the Real Goods
Balance Sheet, or any lockouts, strikes, slowdowns, work stoppages or threats
thereof by or with respect to such employees, which in any such case would
reasonably be expected to have a Real Goods Material Adverse Effect.

During the period from June 24, 2000 to the date of this Agreement, neither Real
Goods nor any of its Subsidiaries has engaged in any conduct that is proscribed
during the period from the date of this Agreement to the Effective Time by
Section 5.3 or agreed in writing during such period prior to the date of this
Agreement to engage in any such conduct.

     Section 3.11.  Litigation; Compliance.

     Except as set forth in Section 3.11 of the Disclosure Schedule:
                            ------------

     (a)  There is no action, suit or proceeding pending against, or (to the
Knowledge of Real Goods) threatened against or affecting, or (to the Knowledge
of Real Goods) any pending investigation against, Real Goods or any of its
Subsidiaries or any of their respective properties before any court or
arbitrator or any governmental body, agency or official which would reasonably
be expected, individually or in the aggregate, to have a Real Goods Material
Adverse Effect or which in any manner challenges or seeks to prevent, enjoin,
alter or materially delay the Merger or any of the other transactions
contemplated by this Agreement.

     (b)  Real Goods and its Subsidiaries are in substantial compliance with all
applicable Laws and Regulations and are not in default with respect to any Order
applicable to Real Goods or any of its Subsidiaries, except such events of
noncompliance or defaults that, individually or in the aggregate, would not
reasonably be expected to have a Real Goods Material Adverse Effect.

     Section 3.12.  Taxes.  (a)  Real Goods and its Subsidiaries have timely
filed all required Tax Returns and such Tax Returns are true, complete and
correct, and Real Goods and its Subsidiaries have timely paid and discharged all
Taxes due in connection with or with respect to the periods or transactions
covered by such Tax Returns and have paid all other Taxes as are due, except
such as are being contested in good faith by appropriate proceedings (to the
extent that any such proceedings are required) and there are no other Taxes that
would be due if asserted by a taxing authority, except Taxes with respect to
which Real Goods is maintaining reserves to the extent required by generally
accepted accounting principles, except where the failure of any of the foregoing
to be true would not, individually or in the aggregate, reasonably be expected
to have a Real Goods Material Adverse Effect.  Except as does not involve or
would not result in liability to Real Goods or any of its Subsidiaries that
would reasonably be expected to have a Real Goods Material Adverse Effect, (i)
there are no Tax Liens on any assets of Real Goods or any of its Subsidiaries
(other than Permitted Encumbrances); and (ii) there is no written claim against
Real Goods or any of its Subsidiaries for any Taxes, and no assessment,

Taxes accruable through the date thereof (including interest and penalties, if
any, thereon and Taxes being contested) in accordance with generally accepted
accounting principles.

     (b)  Neither Real Goods nor any of its Subsidiaries is obligated under any
agreement with respect to industrial development bonds or other obligations with
respect to which the excludability from gross income of the holder for federal
or state income tax purposes could be affected by the transactions contemplated
by this Agreement, and to the Knowledge of Real Goods, neither Real Goods nor
any of its Subsidiaries owns any property of a character, the indirect transfer
of which, as a consequence of the Merger, would give rise to any material
documentary, stamp or other transfer tax.

     (c)  Real Goods is not a United States real property holding corporation
(as defined in Section 897(c)(2) of the Code).

     Section 3.13.  ERISA.

     Except as set forth in Section 3.13 of the Disclosure Schedule:
                            ------------

     (a)  Each Real Goods Employee Plan has been administered and is in
compliance with the terms of such plan and all applicable laws, rules and
regulations where the failure thereof would result in liability that would be
reasonably expected to have a Real Goods Material Adverse Effect.  Each Real
Goods Employee Plan intended to be qualified has received a favorable
determination from the IRS and, to Real Goods' Knowledge, nothing has occurred
since that would adversely affect such qualification. No litigation or
administrative or other proceeding involving any Real Goods Employee Plans has
occurred or, to Real Goods' Knowledge, is threatened where an adverse
determination would result in liability that would be reasonably expected to
have a Real Goods Material Adverse Effect.  Real Goods has not contributed to
any "multiemployer plan", within the meaning of section 3(37) of ERISA.  No
condition exists and no event has occurred that would be expected to constitute
grounds for termination of any Real Goods Employee Plan and neither Real Goods
nor any of its affiliates has incurred any liability arising in connection with
the termination of, or complete or partial withdrawal from, any plan covered or
previously covered by Title IV of ERISA. For purpose of this Section,
"affiliate" of any Person means any other Person which, together with such
Person, would be treated as a single employer under Section 414 of the Code.

arrangement or policy and each plan or arrangement providing for insurance
coverage (including any self-insured arrangements), workers' compensation,
disability benefits, supplemental unemployment benefits, vacation benefits,
retirement benefits or for deferred compensation, profit-sharing, bonuses, stock
options, stock appreciation or other forms of incentive compensation or post-
retirement insurance, compensation or benefits which (i) is not a Real Goods
Employee Plan, (ii) is entered into, maintained or contributed to, as the case
may be, by Real Goods or any of its affiliates and (iii) covers any employee or
former employee of Real Goods or any of its affiliates, has been maintained in
substantial compliance with its terms and with the requirements prescribed by
any and all statutes, orders, rules and regulations that are applicable to such
arrangements except for failures to comply which, singly or in the aggregate,
would not have a Real Goods Material Adverse Effect.

     (c)  Real Goods has not established, and does not maintain, any post-
retirement benefits for its employees, including but not limited to post-
retirement life insurance or post-retirement medical.

     (d)  Real Goods has no agreements that provide for the payment of income or
the provision of benefits (including vesting, entitlement, receipt, creation or
transfer of any rights, privileges, income or title to property or beneficial

incorporated, validly existing and in good standing under the laws of the State
of Colorado, and has all corporate powers and all material governmental
licenses, authorizations, consents and approvals required to carry on its
business as now conducted. Gaiam is duly qualified to do business as a foreign
corporation and is in good standing in each jurisdiction where the character of
the property owned or leased by it or the nature of its activities makes such
qualification necessary, except for those jurisdictions where the failure to be

Adverse Effect.

     Section 4.2.  Corporate Authorization.  The execution, delivery and
performance by Gaiam of this Agreement and the consummation by Gaiam of the
transactions contemplated by this Agreement are within Gaiam's corporate powers
and have been duly authorized by all necessary corporate action.  This Agreement

accordance with its terms, subject to applicable bankruptcy, insolvency or other
similar laws relating to or affecting the enforcement of creditors' rights
generally and to legal principles of general applicability governing the
application and availability of equitable remedies.

     Section 4.3.  Governmental Authorization.  The execution, delivery and
performance by Gaiam of this Agreement and the consummation of the transactions

clearance certificate in accordance with the California Law (b) compliance with
any applicable requirements of the Securities Act, the Exchange Act or any Blue
Sky Laws; and (c) compliance with those Laws, Regulations and Orders
noncompliance with which would not reasonably be expected to have a Gaiam
Material Adverse Effect or to prevent, impair or result in significant delay of
the consummation of the Merger. Without limiting the first sentence of this
Section 4.3, the execution, delivery and performance by Gaiam of this Agreement
and the consummation of the transactions contemplated by this Agreement by Gaiam

by Gaiam of this Agreement and the consummation by Gaiam of the transactions
contemplated by this Agreement do not and will not (a) contravene or conflict
with the articles of incorporation or bylaws of Gaiam or (b) assuming
effectuation of all filings and registrations with, the termination or
expiration of any applicable waiting periods imposed by, and receipt of all
Permits and Orders of, Governmental Authorities indicated as required in Section
4.3,  (i) constitute a default under or give rise to (A) a right of termination,
cancellation, acceleration, amendment or modification with respect to Gaiam or
any of its Subsidiaries, (B) a loss of any benefit to which Gaiam or any of its
Subsidiaries is entitled or (C) an increase in the obligations of Gaiam or any
of its Subsidiaries, in each case, under any provision of any Material Contract
of Gaiam or any of its Subsidiaries which, in any such case, individually or in
the aggregate, would have a Gaiam Material Adverse Effect, (ii) result in the
creation or imposition of any material Lien (other than any Permitted
Encumbrances) on any material asset of Gaiam or any of its Subsidiaries or (iii)
violate or cause a breach under any Law, Regulation, Order or Permit applicable
to Gaiam, its Subsidiaries and their respective assets except for any such
matters that would not reasonably be expected, individually or in the aggregate,
to have a Gaiam Material Adverse Effect.

     Section 4.5.  Capitalization.  The authorized capital stock of Gaiam
consists of 250,000,000 shares, consisting of 150,000,000 shares of Gaiam Class
A, 50,000,000 shares of class B common stock, $.0001 par value per share, and

Gaiam have been duly authorized and validly issued and are fully paid and
nonassessable.

     Section 4.6.  Subsidiaries.  Each of Gaiam's Subsidiaries is a corporation
or other legal entity duly incorporated or organized, validly existing and in
good standing under the laws of its jurisdiction of incorporation or
organization, has all corporate or entity powers and all governmental licenses,
authorizations, consents and approvals required to carry on its business as now
conducted, except to the extent the failure to have such licenses,
authorizations, consents and approvals would not, individually or in the
aggregate, have a Gaiam Material Adverse Effect, and is duly qualified to do
business as a foreign corporation or entity and is in good standing in each
jurisdiction where the character of the property owned or leased by it or the
nature of its activities makes such qualification necessary, except for those
jurisdictions where failure to be so qualified would not, individually or in the
aggregate, have a Gaiam Material Adverse Effect.

     Section 4.7.  SEC Filings.  (a)  Gaiam has filed all required forms,
reports and documents with the SEC since October 28, 1999, including, (i) its
Annual Report on Form 10-K for the fiscal year ended December 31, 1999 (the
"Gaiam 10-K"), (ii) the proxy statement relating to Gaiam's 2000 annual meeting
of shareholders, (iii) its Quarterly Reports on Form 10-Q for the fiscal
quarters ended March 31, 2000 and June 30, 2000 (the "Gaiam 10-Qs") and (iv) all
other reports or registration statements filed by Gaiam with the SEC since
October 28, 1999 (collectively, the "Gaiam SEC Reports") with the SEC, all of
which complied when filed in all material respects with all applicable
requirements of the Securities Act and the Exchange Act.  The audited
consolidated financial statements and unaudited consolidated interim financial
statements of Gaiam and its subsidiaries included or incorporated by reference
in such Gaiam SEC Reports were prepared in accordance with generally accepted
accounting principles applied on a consistent basis during the periods involved
(except as may be indicated in the notes thereto) and present fairly, in all
material respects, the financial position and results of operations and cash
flows of Gaiam and its Subsidiaries on a consolidated basis at the respective
dates and for the respective periods indicated (and in the case of all such
financial statements that are interim financial statements, contain all
adjustments so to present fairly).  Except to the extent that information
contained in any Gaiam SEC Report was revised or superseded by a later filed
Gaiam SEC Report, none of the Gaiam SEC Reports contained any untrue statement
of a material fact or omitted to state any 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.  Gaiam has provided to
Real Goods copies of all other correspondence sent to or received from the SEC
by Gaiam and its Subsidiaries since January 1, 2000 (other than cover letters).

     Section 4.8.  Consolidated Financial Statements.  Gaiam has provided to
Real Goods true and complete copies of the unaudited consolidated balance sheet
of Gaiam at June 30, 2000 (the "Gaiam Balance Sheet") and the unaudited
consolidated statements of income, shareholders' equity and cash flow of Gaiam
for the period from December 31, 1999 through June 30, 2000. Such financial
statements fairly present, in all material respects, the financial position of
Gaiam at June 30, 2000, and the results of operations of Gaiam for the period
then ended, and have been prepared in accordance with generally accepted
accounting principles applied on a consistent basis, except that such financial
statements will not include any footnote disclosures that might otherwise be
required to be included by generally accepted

                                      A-22
<PAGE>

accounting principles, and shall also be subject to normal non-recurring year-
end audit adjustments. The Gaiam Balance Sheet reflects all liabilities of
Gaiam, whether absolute, accrued or contingent, as of the date thereof of the
type required to be reflected or disclosed on a balance sheet prepared in
accordance with generally accepted accounting principles (applied in a manner
consistent with the notes of the financial statements included in the Gaiam 10-
K).

     Section 4.9.   Disclosure Documents. None of the information supplied or to
be supplied by or on behalf of Gaiam or Gaiam Subsidiary for inclusion or
incorporation by reference in the Registration Statement will, at the time the
Registration Statement becomes effective under the Securities Act, contain any
untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary to make the statements therein, in light of
the circumstances under which they were made, not misleading. The Registration
Statement (except for information relating solely to Real Goods) will comply as
to form in all material respects with the provisions of the Securities Act and
the Exchange Act.

     Section 4.10.  Absence of Certain Changes.  Except for this Agreement,
since the date of the Gaiam Balance Sheet, Gaiam and its Subsidiaries have
conducted their business in all material respects in the ordinary course
consistent with past practice and there has not been:

     (a)  any event, occurrence or development (including the commencement of
any action, suit or proceedings or, to the Knowledge of Gaiam, any
investigation) of a state of circumstances or facts which, individually or
together with other similar events, has had or reasonably would be expected to
have a Gaiam Material Adverse Effect;

     (b)  any declaration, setting aside or payment of any dividend or other
distribution with respect to any shares of capital stock of Gaiam, or any
material repurchase, redemption (other than the receipt of Gaiam Class A in
payment of the exercise price of stock options and Taxes in respect of such
exercise) or other acquisition by Gaiam of any outstanding shares of capital
stock or other securities of, or other ownership interests in, Gaiam;

     (c)  any amendment of any material term of any outstanding security of
Gaiam or any of its Subsidiaries other than amendments to the terms of the
existing credit facilities of Gaiam or its Subsidiaries or borrowings under such
facilities; or

     (d)  any damage, destruction or other casualty loss (whether or not covered
by insurance) affecting the business or assets of Gaiam or any of its
Subsidiaries which, individually or in the aggregate, has had or would
reasonably be expected to have a Gaiam Material Adverse Effect.

     Section 4.11.  Litigation; Compliance.

     (a)  There is no action, suit or proceeding pending against, or (to the
Knowledge of Gaiam) threatened against or affecting, or (to the Knowledge of
Gaiam) any pending investigation against, Gaiam or any of its Subsidiaries or
any of their respective properties before any court or arbitrator or any
governmental body, agency or official which would reasonably be expected,
individually or in the aggregate, to have a Gaiam Material Adverse Effect or
which in any manner challenges or seeks to prevent, enjoin, alter or materially
delay the Merger or any of the other transactions contemplated by this
Agreement.

     (b)  Gaiam and its Subsidiaries are in substantial compliance with all
applicable Laws and Regulations and are not in default with respect to any Order
applicable to Gaiam or any of its

                                      A-23
<PAGE>

Subsidiaries, except such events of noncompliance or defaults that, individually
or in the aggregate, would not reasonably be expected to have a Gaiam Material
Adverse Effect.

     Section 4.12.  Taxes.  (a)  Gaiam and its Subsidiaries have timely filed
all required Tax Returns and such Tax Returns are true, complete and correct,
and Gaiam and its Subsidiaries have timely paid and discharged all Taxes due in
connection with or with respect to the periods or transactions covered by such
Tax Returns and have paid all other Taxes as are due, except such as are being
contested in good faith by appropriate proceedings (to the extent that any such
proceedings are required) and there are no other Taxes that would be due if
asserted by a taxing authority, except Taxes with respect to which Gaiam is
maintaining reserves to the extent required by generally accepted accounting
principles, except where the failure of any of the foregoing to be true would
not, individually or in the aggregate, reasonably be expected to have a Gaiam
Material Adverse Effect.  Except as does not involve or would not result in
liability to Gaiam or any of its Subsidiaries that would reasonably be expected
to have a Gaiam Material Adverse Effect, (i) there are no Tax Liens on any
assets of Gaiam or any of its Subsidiaries (other than Permitted Encumbrances);
and (ii) there is no written claim against Gaiam or any of its Subsidiaries for
any Taxes, and no assessment, deficiency or adjustment has been asserted or
proposed with respect to any Tax Return.  The accruals and reserves (including
deferred taxes) reflected in Gaiam Balance Sheet are in all material respects
adequate to cover all Taxes accruable through the date thereof (including
interest and penalties, if any, thereon and Taxes being contested) in accordance
with generally accepted accounting principles.

     (b)  Neither Gaiam nor any of its Subsidiaries is obligated under any
agreement with respect to industrial development bonds or other obligations with
respect to which the excludability from gross income of the holder for federal
or state income tax purposes could be affected by the transactions contemplated
by this Agreement, and to the Knowledge of Gaiam, neither Gaiam nor any of its
Subsidiaries owns any property of a character, the indirect transfer of which,
as a consequence of the Merger, would give rise to any material documentary,
stamp or other transfer tax.

     Section 4.13.  ERISA..

     (a)  Each Gaiam Employee Plan has been administered and is in compliance
with the terms of such plan and all applicable laws, rules and regulations where
the failure thereof would result in liability that would be reasonably expected
to have a Gaiam Material Adverse Effect.  Each Gaiam Employee Plan intended to
be qualified has received a favorable determination from the IRS and, to Gaiam's
Knowledge, nothing has occurred since that would adversely affect such
qualification. No litigation or administrative or other proceeding involving any
Gaiam Employee Plans has occurred or, to Gaiam's Knowledge, is threatened where
an adverse determination would result in liability that would be reasonably
expected to have a Gaiam Material Adverse Effect.  Gaiam has not contributed to
any "multiemployer plan", within the meaning of section 3(37) of ERISA.  No
condition exists and no event has occurred that would be expected to constitute
grounds for termination of any Gaiam Employee Plan and neither Gaiam nor any of
its affiliates has incurred any liability arising in connection with the
termination of, or complete or partial withdrawal from, any plan covered or
previously covered by Title IV of ERISA. For purpose of this Section,
"affiliate" of any Person means any other Person which, together with such
Person, would be treated as a single employer under Section 414 of the Code.

     (b)  Each enforceable employment, severance or other similar contract,
arrangement or policy and each plan or arrangement providing for insurance
coverage (including any self-insured arrangements), workers' compensation,
disability benefits, supplemental unemployment benefits, vacation benefits,
retirement benefits or for deferred compensation, profit-sharing, bonuses, stock
options, stock appreciation or other forms of incentive compensation or post-
retirement insurance, compensation

                                      A-24
<PAGE>

or benefits which (i) is not a Gaiam Employee Plan, (ii) is entered into,
maintained or contributed to, as the case may be, by Gaiam or any of its
affiliates and (iii) covers any employee or former employee of Gaiam or any of
its affiliates, has been maintained in substantial compliance with its terms and
with the requirements prescribed by any and all statutes, orders, rules and
regulations that are applicable to such arrangements except for failures to
comply which, singly or in the aggregate, would not have a Gaiam Material
Adverse Effect.

     (c)  Gaiam has not established, and does not maintain, any post-
retirement benefits for its employees, including but not limited to post-
retirement life insurance or post-retirement medical.

     Section 4.14.  Permits.  Gaiam and its Subsidiaries have all Permits as are
necessary to carry on their businesses as currently conducted, except for any
such Permits for which Gaiam has made due application and except for any such
Permits that the failure to possess which, individually or in the aggregate,
would not reasonably be expected to have a Gaiam Material Adverse Effect.  Gaiam
has not received notice from any Governmental Authority (i) that such Permits
are not in full force and effect or have been violated, in either case in any
respect that would reasonably be expected to have a Gaiam Material Adverse
Effect or (ii) threatening to revoke or suspend any such Permits which, in any
such case, would reasonably be expected to have a Gaiam Material Adverse Effect.

     Section 4.15.  Finders' Fees.  There is no investment banker, broker,
finder or other intermediary which has been retained by or is authorized to act
on behalf of Gaiam or any of its Subsidiaries who might be entitled to any fee
or commission from Real Goods or any of its Subsidiaries in connection with the
transactions contemplated by this Agreement.

     Section 4.16.  Environmental Matters.  Except for matters that,
individually or in the aggregate, would not reasonably be expected to have a
Gaiam Material Adverse Effect, (a) the properties, operations and activities of
Gaiam and its Subsidiaries are in compliance with all applicable Environmental
Laws; (b) Gaiam and its Subsidiaries and the properties and operations of Gaiam
and its Subsidiaries are not subject to any existing, pending or, to the
Knowledge of Gaiam, threatened action; suit, or proceeding by or before any
Court or Governmental Authority under any Environmental Law; and (c) all
Permits, if any, required to be obtained or filed by Gaiam or any of its
Subsidiaries under any Environmental Law in connection with the business of
Gaiam and its Subsidiaries have been obtained or filed and are valid and

Real Goods' Board of Directors to do so, in the event that Real Goods or any of
Real Goods' Representatives shall receive any offer or proposal, directly or

Directors not to do so, in no event shall Real Goods enter into a definitive
agreement in connection with the Acquisition Proposal less than three business
days after Real Goods' notification to Gaiam of an inquiry or proposal relating
to an Acquisition Proposal.  Within the three business day period referred to

of Real Goods Common Shares or other securities of Real Goods, or by any other
Person, which relates to or seeks to challenge or enjoin the transactions
contemplated by this Agreement.

     Section 5.5.  Antitakeover Statutes.  If any takeover statute is or may
become applicable to the transactions contemplated by this Agreement, Real Goods
and the members of its Board of Directors shall

                                      A-30
<PAGE>

use all reasonable efforts to grant such approvals and to take such actions as
are necessary so that the transactions contemplated by this Agreement may be
consummated as promptly as practicable on the terms contemplated by this
Agreement and otherwise act to eliminate or minimize the effects of any takeover
statute on any of the transactions contemplated by this Agreement.

     Section 5.6.  Covenants of Gaiam.  Except as expressly contemplated by this
Agreement or consented to in writing by Real Goods, during the period from the
execution of this Agreement by Real Goods to the Effective Time, (a) Gaiam will,
and will cause its Subsidiaries to, use all commercially reasonable efforts to
comply in all material respects with all applicable Laws, Regulations and
Orders, and (b) Gaiam will not, and will not permit any of its Subsidiaries to
(i) take or agree or commit to take any action that would make any
representation or warranty of Gaiam hereunder inaccurate in any respect at, or
as of any time prior to, the Effective Time such that the conditions set forth
in Section 7.2(a) would not be satisfied, (ii) omit or agree or commit to omit
to take any action necessary to prevent any such representation or warranty from
being inaccurate in any respect at any such time such that the conditions set
forth in Section 7.2(a) would not be satisfied, or (iii) take, cause or permit
to be taken any action, whether before or after the Effective Time, that could
reasonably be expected to prevent the Merger from constituting a
"reorganization" within the meaning of Section 368(a) of the Code.

     Section 5.7.  Certain Employee Matters.  Prior to the Effective Time, Gaiam
will consult with Real Goods and will use reasonable best efforts to identify
any Real Goods employees whose employment will be terminated as a result of the
Merger.  Notwithstanding anything to the contrary set forth in this Agreement,
prior to the Effective Time, Real Goods will pay or arrange for the payment of
severance to each Real Goods employee so identified, provided that such employee
has been an employee of Real Goods for at least one year as of the Effective
Time, and provided further that such employee continues employment until the
date employment is terminated.  Such severance shall equal (a) two weeks of
salary, plus (b) one additional week of salary for each year of employment in
excess of one year.  For purposes of this Section, any Real Goods employee who
is transferred after the Merger to a work location more than 75 miles from such
employee's current work location shall be deemed to have been terminated as a
result of the Merger.  Gaiam agrees that all Real Goods employees who continue
employment with Gaiam or Real Goods following the Merger shall be entitled to
receive seniority credit, in any vacation and insurance plans, for any
employment at Real Goods prior to the Merger.  Notwithstanding anything to the
contrary set forth in this Agreement, Gaiam consents to the transfer of all
rights under John Schaeffer's split dollar life insurance policy to Mr.
Schaeffer or his insurance trust and to any amendment or termination of
agreements entered into by Real Goods in connection with such policy.

                            Covenants of Each Party

     Each party agrees that:

     Section 6.1.  Preparation of the Registration Statement; Shareholder
Meeting.

     (a)  As soon as practicable following the date of this Agreement, Gaiam and
Real Goods shall prepare and file with the SEC the Registration Statement, in

use commercially reasonable efforts to have the Registration Statement declared
effective under the Securities Act as promptly as practicable after such filing.
The Proxy Statement shall include the recommendation of the Board of Directors
of Real Goods in favor of approval and adoption of this Agreement and the
Merger, except to the extent the Board of Directors of

                                      A-31

shareholders.

     (b)  Gaiam and Real Goods shall make all necessary filings with respect to
the Merger and the transactions contemplated thereby under the Securities Act
and the Exchange Act and applicable state blue sky laws and the rules and
regulations thereunder.  Gaiam shall also take any action required to be taken
under any applicable state securities laws in connection with the issuance of
Gaiam Class A in the Merger.  No filing of, or amendment or supplement to, the
Registration Statement will be made by Gaiam without providing Real Goods and
its counsel the opportunity to review and comment thereon.  Gaiam will advise
Real Goods, promptly after it receives notice thereof, of the time when the
Registration Statement has become effective or any supplement or amendment has
been filed, the issuance of any stop order, the suspension of the qualification
of the Gaiam Class A issuable in connection with the Merger for offering or sale
in any jurisdiction, or any request by the SEC for amendment of the Registration
Statement or comments thereon and responses thereto or requests by the SEC for
additional information.  If at any time prior to the Effective Time any
information relating to Gaiam or Real Goods, or any of their respective
affiliates, officers or directors, should be discovered by Gaiam or Real Goods
which should be set forth in an amendment or supplement to any of the
Registration Statement, so that any of such documents would not include any
misstatement of a material fact or omit to state any material fact necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading, the party which discovers such information shall promptly
notify the other parties hereto and an appropriate amendment or supplement
describing such information shall be promptly filed with the SEC and, to the
extent required by law, disseminated to the shareholders of Real Goods.

     (c)  Real Goods shall, as soon as practicable following the effectiveness
of the Registration Statement, duly call, give notice of, convene and hold a
meeting of its shareholders (the "Real Goods Shareholder Meeting") for the
purpose of obtaining the approval and adoption (the "Real Goods Shareholder
Approval") of the shareholders of Real Goods of this Agreement and the Merger
and shall, through its Board of Directors, recommend to its shareholders the
approval and adoption of this Agreement and the Merger, and shall use all
commercially reasonable efforts to solicit from its shareholders proxies in
favor of approval and adoption of this Agreement and the Merger; provided,
                                                                 --------
however, that such recommendation is subject to Section 5.3 hereof.
-------

     Section 6.2.  Letters and Consents of Real Goods' Accountants.  Real Goods
shall use all commercially reasonable efforts to cause to be delivered to Gaiam
all consents required from Real Goods' independent accountants necessary to
effect the registration of the Gaiam Class A and make any required filing with
the SEC in connection with the Merger and the transactions contemplated thereby.

     Section 6.3.  Letters and Consents of Gaiam's Accountants.  Gaiam shall use
all commercially reasonable efforts to cause to be delivered to Gaiam all
consents required from its independent accountants necessary to effect the
registration of the Gaiam Class A and make any required filing with the SEC in
connection with the Merger and the transactions contemplated thereby.

     Section 6.4.  Reasonable Efforts.  (a) Subject to the terms and conditions
of this Agreement, each party shall use, and shall cause each of its respective
Subsidiaries to use, all commercially reasonable efforts (i) to take, or to
cause to be taken, all appropriate action, and to do, or to cause to be done,
all things necessary, proper or advisable under applicable Law or otherwise to
consummate and make effective the transactions contemplated by this Agreement,
(ii) to obtain from any Governmental Authorities any Licenses, Permits or Orders
required to be obtained by such party or any of its

                                      A-32
<PAGE>

Subsidiaries in connection with the authorization, execution and delivery of
this Agreement and the performance of its obligations hereunder, (iii) to make
all necessary filings and thereafter to make promptly any other required
submissions, with respect to this Agreement required under any other applicable
Law, Regulation or Order and (iv) to provide all necessary information for the
Registration Statement; provided, that Gaiam and Real Goods shall cooperate with
each other in connection with the making of all such filings and in supplying
any information requested supplementally or by second request from any
Governmental Authority.

       (b)  The parties agree to cooperate and to cause their respective
Subsidiaries to cooperate with respect to, and agree to use all commercially
reasonable efforts vigorously to contest and resist and to have vacated, lifted,
reversed or overturned, any action, including legislative, administrative or
judicial action, including any Order (whether temporary, preliminary or
permanent) of any Governmental Authority, that is in effect and that restricts,
prevents or prohibits the consummation of the transactions contemplated by this
Agreement.  Each of the parties also agrees to take any and all commercially
reasonable actions that may be required by any Governmental Authority as a
condition to the granting of any Permit or Order required in order to permit the
consummation of the transactions contemplated by this Agreement or as may be
required to vacate, lift, reverse or overturn any administrative or judicial
action that would otherwise cause any condition to the Effective Time not to be
satisfied; provided, however, that in no event shall either party be required to
take any action that could reasonably be expected to have a Real Goods Material
Adverse Effect or a Gaiam Material Adverse Effect or to result in a breach of
this Agreement.

       (c)  Each of the parties shall use, and shall cause its Subsidiaries to
use, all commercially reasonable efforts to obtain from all Persons (other than
Governmental Authorities) all consents that are (i) necessary, proper or
advisable or (ii) otherwise required under any contracts, licenses, leases,
easements or other agreements to which such party or any of its Subsidiaries is
a party or by which it is bound, in order to permit such party to perform its
obligations hereunder.

       (d)  If any party shall fail to obtain any third party consent described
in Section 6.4(c), such party shall use all commercially reasonable efforts, and
shall take any such actions reasonably requested by the other parties, to limit
the adverse effect upon Gaiam and its Subsidiaries, and Real Goods and its
Subsidiaries, and each of their respective businesses resulting, or which could
reasonably be expected to result after the Effective Time, from the failure to
obtain such consent.

       (e)  Upon learning thereof, each party shall promptly notify the other
parties of (i) any complaints, investigations or hearings (or communications

right to terminate this Agreement under this Section;

     (g)  by Gaiam (i) if the Board of Directors of Real Goods shall have

Goods of such breach, through the exercise by Gaiam of its reasonable best
efforts, so that the condition in Section 7.2(a) would be satisfied, and so long
as Gaiam continues to exercise such reasonable best efforts, Real Goods will not
have the right to terminate this Agreement under this Section;

     (k)  by Real Goods upon a breach of any covenant or agreement on the part
of Gaiam set forth in this Agreement such that the condition set forth in
Section 7.2(a) would not be satisfied; provided that, if such breach is curable
prior to the date 30 days after notice to Gaiam by Real Goods of such breach,

that, prior to termination under this Section 8.1(m), Gaiam must give Real Goods
two business days notice of its intent to terminate and if Real Goods agrees to
decrease the Exchange Ratio to the Decreased Exchange Ratio (as defined below)
within such two business day period, Gaiam shall not have the right to terminate
this Agreement under this Section 8.1(m) and the Exchange Ratio in that case

       The party desiring to terminate this Agreement pursuant to clauses 8.1(b)
     through 8.1(m) shall give written notice of such termination to the other
     parties in accordance with Section 8.1.

     Section 8.2.  Effect of Termination.  If this Agreement is terminated

no liability on the part of any party hereto, except for

                                      A-38
<PAGE>

liability or damages resulting from a willful breach of this Agreement and
except that the agreements contained in this Section 8.2 and in Sections 8.3 and
Article 9 shall survive the termination hereof.

     Section 8.3.  Certain Fees.

     (a)  Except as provided in Section 8.3(b), all costs and expenses incurred
in connection with this Agreement shall be paid by the party incurring such cost
or expense.

     (b)  In the event of a termination of this Agreement by Gaiam pursuant to
Section 8.1(g) or by Real Goods pursuant to Section 8.1(h), then Real Goods
shall pay Gaiam by wire transfer of immediately available funds to an account
specified by Gaiam, within two business days, $1,000,000 to reimburse Gaiam for
its documented fees and expenses (including the fees and expenses of counsel,
accountants, consultants and advisors) incurred in connection with this
Agreement and the transactions contemplated hereby and as liquidated damages.

     (c)  In the event of a termination of this Agreement by Gaiam for any
reason other than as set forth in Section 8.1, then Gaiam shall pay Real Goods

documented fees and expenses (including the fees and expenses of counsel,
accountants, consultants and advisors) incurred in connection with this
Agreement and the transactions contemplated hereby and as liquidated damages.

     (d)  By agreeing to liquidated damages in Section 8.3(b) and 8.3(c), the
parties acknowledge that (i) such liquidated damages are an integral part of the
transactions contemplated by this Agreement and constitute liquidated damages
and not a penalty, and (ii) such liquidated damages are necessary because actual
damages arising from the loss of opportunity would not be determinable with any
degree of certainty.  If a party fails to promptly pay the liquidated damages
due under Section 8.3(b) or 8.3(c), the defaulting party shall pay the costs and
expenses (including legal fees and expenses) in connection with any action,
including the filing of any lawsuit or other legal action, taken to collect
payment, together with interest on the amount of any unpaid fee at the publicly
announced prime rate as reported in The Wall Street Journal from the date such
damages were required to be paid.

performance, a temporary restraining order, a temporary or permanent injunction

application thereof to either party or set of circumstances shall in any
jurisdiction and to any extent, be finally held invalid or unenforceable, such
term or provision shall only be ineffective as to such jurisdiction, and only to
the extent of such invalidity or unenforceability, without invalidating or
rendering unenforceable any other terms or provisions of this Agreement or under
any other circumstances, and the parties shall negotiate in good faith a
substitute provision which comes as close as possible to the invalidated or
unenforceable term or provision, and which puts each party in a position as
nearly comparable as possible to the position it would have been in but for the
finding of invalidity or unenforceability, while remaining valid and
enforceable.

agreement among the parties to this Agreement with respect to the subject matter

writing delivered pursuant hereto shall not survive the Effective Time or, if

                     [FORM OF REAL GOODS AFFILIATE LETTER]


Ladies and Gentlemen:

     I have been advised that I may be considered to be an "affiliate" of Real
Goods Trading Corporation, Inc. ("Real Goods" or the "Company") for purposes of
Rule 145 under the Securities Act of 1933, as amended (the "Securities Act").

     Gaiam, Inc. ("Gaiam") and Real Goods have entered into an Agreement and
Plan of Merger dated as of October 13, 2000 (the "Merger Agreement").  Upon
consummation of the transactions contemplated by the Merger Agreement (the
"Merger"), I will receive shares of capital stock of Gaiam for all of the shares
of capital stock of Real Goods owned by me or as to which I may be deemed a
beneficial owner.  I own ______ shares of common stock of Real Goods.  Such
shares will be converted in the Merger into shares of common stock of Gaiam as
described in the Merger Agreement.  The shares of Real Goods capital stock and
Gaiam capital stock owned by me or as to which I may deem to be a beneficial
owner prior to the Merger are hereinafter collectively referred to as the "Pre-
Merger Stock" and the shares of Gaiam capital stock received by me in the Merger
are hereinafter collectively referred to as the "Exchange Stock."  This
agreement is hereinafter referred to as the "Letter Agreement."

     I represent and warrant to, and agree with, Real Goods and Gaiam that:

A.  I have read this Letter Agreement and the Merger Agreement and have
discussed their requirements and other applicable limitations upon my ability to
sell, transfer or otherwise dispose of the Pre-Merger Stock and Exchange Stock,
to the extent I felt necessary, with my counsel or counsel for the Company.

B.  The shares of common stock of Gaiam that I shall receive in exchange for my
shares of common stock of the Company are not being acquired by me with a view
to their distribution except to the extent and in the manner provided for in
paragraph (d) of Rule 145 under the Securities Act.

C.  I agree with you not to dispose of any such shares of common stock of Gaiam
in any manner that would violate Rule 145.  I further agree with you that the
certificate or certificates representing such shares of common stock of Gaiam
may bear a legend referring to the restrictions on disposition thereof in
accordance with the provisions of the foregoing paragraph and that stop transfer
instructions may be filed with respect to such shares with the transfer agent
for such shares.

D.  I understand that stop transfer instructions will be given to the Company,
Gaiam and their respective transfer agents, as the case may be, with respect to
the shares of Pre-Merger Stock and the Exchange Stock in connection with the
restrictions set forth herein.

     It is understood and agreed that this Letter Agreement shall terminate and
be of no further force and effect if the Merger Agreement is terminated pursuant
to the terms thereof.

     The agreements made by me in the foregoing paragraphs are on the
understanding and condition that you agree, in the event that any shares may be
disposed of in accordance with the

                                      A-8
<PAGE>

provisions of the paragraphs above, to deliver in exchange for the certificate
or certificates representing such shares a new certificate or certificates
representing such shares not bearing the legend and not subject to the stop
transfer instruction referred to in paragraph D above, and so long as I hold
shares of stock subject to the provisions of this agreement (but not for a
period in excess of two years from the date of consummation of the Merger) to
file with the Securities and Exchange Commission or otherwise make publicly
available all information about Gaiam, to the extent available to you without
unreasonable effort or expense, necessary to enable me to resell shares under
the provisions of paragraph (d) of Rule 145.

     This Letter Agreement shall be binding on my heirs, legal representatives
and successors.

Very truly yours,

             CHAPTER 13 OF THE CALIFORNIA GENERAL CORPORATION LAW

Section 1300. Reorganization or short-form merger; dissenting shares; corporate
purchase at fair market value; definitions

     (a)  If the approval of the outstanding shares (Section 152) of a
corporation is required for a reorganization under subdivisions (a) and (b) or
subdivision (e) or (f) of Section 1201, each shareholder of the corporation
entitled to vote on the transaction and each shareholder of a subsidiary
corporation in a short-form merger may, by complying with this chapter, require
the corporation in which the shareholder holds shares to purchase for cash at
their fair market value the shares owned by the shareholder which are dissenting
shares as defined in subdivision

     (b)  The fair market value shall be determined as of the day before the
first announcement of the terms of the proposed reorganization or short-form
merger, excluding any appreciation or depreciation in consequence of the
proposed action, but adjusted for any stock split, reverse stock split or share
dividend which becomes effective thereafter.

     (c)  As used in this chapter, "dissenting shares" means shares which come
within all of the following descriptions:

          (1)  Which were not immediately prior to the reorganization or short-
     form merger either (A) listed on any national securities exchange certified
     by the Commissioner of Corporations under subdivision (o) of Section 25100
     or (B) listed on the list of National Market System of the Nasdaq Stock
     Market, and the notice of meeting of shareholders to act upon the
     reorganization summarizes this section and Sections 1301, 1302, 1303 and
     1304; provided, however, that this provision does not apply to any shares
     with respect to which there exists any restriction on transfer imposed by
     the corporation or by any law or regulation; and provided, further, that
     this provision does not apply to any class of shares described in
     subparagraph (A) or (B) if demands for payment are filed with respect to 5
     percent or more of the outstanding shares of that class.

          (2)  Which were outstanding on the date for the determination of
     shareholders entitled to vote on the reorganization and (A) were not voted
     in favor of the reorganization or, (B) if described in subparagraph (A) or
     (B) of paragraph (1) (without regard to the provisos in that paragraph),
     were voted against the reorganization, or which were held of record on the
     effective date of a short-form merger; provided, however, that subparagraph
     (A) rather than subparagraph (B) of this paragraph applies in any case
     where the approval required by Section 1201 is sought by written consent
     rather than at a meeting.

                                      B-1
<PAGE>

          (3)  Which the dissenting shareholder has demanded that the
     corporation purchase at their fair market value, in accordance with Section
     1301.

     in accordance with Section 1302.

     (c)  As used in this chapter, "dissenting shareholder" means the
recordholder of dissenting shares and includes a transferee of record.

Section 1301. Notice to holders of dissenting shares in reorganizations; demand
for purchase; time; contents

     (a)  If, in the case of a reorganization, any shareholders of a corporation
have a right under Section 1300, subject to compliance with paragraphs (3) and
(4) of subdivision (b) thereof, to require the corporation to purchase their
shares for cash, such corporation shall mail to each such shareholder a notice
of the approval of the reorganization by its outstanding shares (Section 152)
within 10 days after the date of such approval, accompanied by a copy of
Sections 1300, 1302, 1303, 1304 and this section, a statement of the price
determined by the corporation to represent the fair market value of the
dissenting shares, and a brief description of the procedure to be followed if
the shareholder desires to exercise the shareholder's right under such sections.
The statement of price constitutes an offer by the corporation to purchase at
the price stated any dissenting shares as defined in subdivision (b) of Section
1300, unless they lose their status as dissenting shares under Section 1309.

     (b)  Any shareholder who has a right to require the corporation to purchase
the shareholder's shares for cash under Section 1300, subject to compliance with
paragraphs (3) and (4) of subdivision (b) thereof, and who desires the
corporation to purchase such shares shall make written demand upon the
corporation for the purchase of such shares and payment to the shareholder in
cash of their fair market value. The demand is not effective for any purpose
unless it is received by the corporation or any transfer agent thereof (1) in
the case of shares described in clause (i) or (ii) of paragraph (1) of
subdivision (b) of Section 1300 (without regard to the provisos in that
paragraph), not later than the date of the shareholders' meeting to vote upon
the reorganization, or (2) in any other case within 30 days after the date on
which the notice of the approval by the outstanding shares pursuant to
subdivision (a) or the notice pursuant to subdivision (i) of Section 1110 was
mailed to the shareholder.

     (c)  The demand shall state the number and class of the shares held of
record by the shareholder which the shareholder demands that the corporation
purchase and shall contain a statement of what such shareholder claims to be the
fair market value of those shares as of the day before the announcement of the
proposed reorganization or short-form merger. The statement of fair market value
constitutes an offer by the shareholder to sell the shares at such price.

Section 1302. Submission of share certificates for endorsement; uncertificated
securities

     Within 30 days after the date on which notice of the approval by the
outstanding shares or the notice pursuant to subdivision (i) of Section 1110 was
mailed to the shareholder, the shareholder shall submit to the corporation at
its principal office or at the office of any transfer agent thereof, (a) if the
shares are certificated securities, the shareholder's certificates representing
any shares which the shareholder demands that the corporation purchase, to be
stamped or endorsed with a statement that the shares are dissenting shares or to
be exchanged for certificates of appropriate denomination so stamped or endorsed
or (b) if the shares are uncertificated securities, written notice of the number
of shares which the shareholder demands that the corporation purchase. Upon
subsequent transfers of the dissenting shares on the books of the corporation,
the new certificates, initial transaction statement, and other written
statements issued therefor shall bear a like statement, together with the name
of the original dissenting holder of the shares.

Section 1303. Payment of agreed price without interest; agreement fixing fair
market value; filing; time of payment

     (a)  If the corporation and the shareholder agree that the shares are
dissenting shares and agree upon the price of the shares, the dissenting
shareholder is entitled to the agreed price with interest thereon at the legal
rate on judgments from the date of the agreement. Any agreements fixing the fair
market value of any dissenting shares as between the corporation and the holders
thereof shall be filed with the secretary of the corporation.

     (b)  Subject to the provisions of Section 1306, payment of the fair market
value of dissenting shares shall be made within 30 days after the amount thereof
has been agreed or within 30 days after any statutory or contractual conditions
to the reorganization are satisfied, whichever is later, and in the case of
certificated securities, subject to surrender of the certificates therefor,
unless provided otherwise by agreement.

Section 1304. Action to determine whether shares are dissenting shares or fair
market value; limitation; joinder; consolidation; determination of issues;
appointment of appraisers

     (a)  If the corporation denies that the shares are dissenting shares, or
the corporation and the shareholder fail to agree upon the fair market value of
the shares, then the shareholder demanding purchase of such shares as dissenting
shares or any interested corporation, within six months after the date on which
notice of the approval by the outstanding shares (Section 152) or notice
pursuant to subdivision (i) of Section 1110 was mailed to the shareholder, but
not thereafter, may file a complaint in the superior court of the proper county
praying the court to determine whether the shares are dissenting shares or the
fair market value of the dissenting shares or both or may intervene in any
action pending on such a complaint.

                                      B-3
<PAGE>

     (b)  Two or more dissenting shareholders may join as plaintiffs or be
joined as defendants in any such action and two or more such actions may be
consolidated.

     (c)  On the trial of the action, the court shall determine the issues. If
the status of the shares as dissenting shares is in issue, the court shall first
determine that issue. If the fair market value of the dissenting shares is in
issue, the court shall determine, or shall appoint one or more impartial
appraisers to determine, the fair market value of the shares.

Section 1305. Report of appraisers; confirmation; determination by court;
judgment; payment; appeal; costs

     (a)  If the court appoints an appraiser or appraisers, they shall proceed
forthwith to determine the fair market value per share. Within the time fixed by
the court, the appraisers, or a majority of them, shall make and file a report
in the office of the clerk of the court. Thereupon, on the motion of any party,
the report shall be submitted to the court and considered on such evidence as
the court considers relevant. If the court finds the report reasonable, the
court may confirm it.

     (b)  If a majority of the appraisers appointed fail to make and file a
report within 10 days from the date of their appointment or within such further
time as may be allowed by the court or the report is not confirmed by the court,
the court shall determine the fair market value of the dissenting shares.

     (c)  Subject to the provisions of Section 1306, judgment shall be rendered
against the corporation for payment of an amount equal to the fair market value
of each dissenting share multiplied by the number of dissenting shares which any
dissenting shareholder who is a party, or who has intervened, is entitled to
require the corporation to purchase, with interest thereon at the legal rate
from the date on which judgment was entered.

     (d)  Any such judgment shall be payable forthwith with respect to
uncertificated securities and, with respect to certificated securities, only
upon the endorsement and delivery to the corporation of the certificates for the
shares described in the judgment. Any party may appeal from the judgment.

     (e)  The costs of the action, including reasonable compensation to the
appraisers to be fixed by the court, shall be assessed or apportioned as the
court considers equitable, but, if the appraisal exceeds the price offered by
the corporation, the corporation shall pay the costs (including in the
discretion of the court attorneys' fees, fees of expert witnesses and interest
at the legal rate on judgments from the date of compliance with Sections 1300,
1301 and 1302 if the value awarded by the court for the shares is more than 125
percent of the price offered by the corporation under subdivision (a) of Section
1301).

Section 1306. Prevention of immediate payment; status as creditors; interest.


                                      B-4
<PAGE>

     To the extent that the provisions of Chapter 5 prevent the payment to any
holders of dissenting shares of their fair market value, they shall become
creditors of the corporation for the amount thereof together with interest at
the legal rate on judgments until the date of payment, but subordinate to all
other creditors in any liquidation proceeding, such debt to be payable when
permissible under the provisions of Chapter 5.

Section 1307. Dividends on dissenting shares

     Cash dividends declared and paid by the corporation upon the dissenting
shares after the date of approval of the reorganization by the outstanding
shares (Section 152) and prior to payment for the shares by the corporation
shall be credited against the total amount to be paid by the corporation
therefor.

Section 1308. Rights of dissenting shareholders pending valuation; withdrawal of
demand for payment.

     Except as expressly limited in this chapter, holders of dissenting shares
continue to have all the rights and privileges incident to their shares, until
the fair market value of their shares is agreed upon or determined. A dissenting
shareholder may not withdraw a demand for payment unless the corporation
consents thereto.

Section 1309. Termination of dissenting share and shareholder status.

     Dissenting shares lose their status as dissenting shares and the holders
thereof cease to be dissenting shareholders and cease to be entitled to require
the corporation to purchase their shares upon the happening of any of the
following:

     (a)  The corporation abandons the reorganization. Upon abandonment of the
reorganization, the corporation shall pay on demand to any dissenting
shareholder who has initiated proceedings in good faith under this chapter all
necessary expenses incurred in such proceedings and reasonable attorneys' fees.

     (b)  The shares are transferred prior to their submission for endorsement
in accordance with Section 1302 or are surrendered for conversion into shares of
another class in accordance with the articles.

     (c)  The dissenting shareholder and the corporation do not agree upon the
status of the shares as dissenting shares or upon the purchase price of the
shares, and neither files a complaint or intervenes in a pending action as
provided in Section 1304, within six months after the date on which notice of
the approval by the outstanding shares or notice pursuant to subdivision (i) of
Section 1110 was mailed to the shareholder.

     (d)  The dissenting shareholder, with the consent of the corporation,
withdraws the shareholder's demand for purchase of the dissenting shares.

Section 1310. Suspension of right to compensation or valuation proceedings;
litigation of shareholders' approval

     If litigation is instituted to test the sufficiency or regularity of the
votes of the shareholders in authorizing a reorganization, any proceedings under
Sections 1304 and 1305 shall be suspended until final determination of such
litigation.

Section 1311. Exempt shares

     This chapter, except Section 1312, does not apply to classes of shares
whose terms and provisions specifically set forth the amount to be paid in
respect to such shares in the event of a reorganization or merger.

Section 1312. Right of dissenting shareholder to attack, set aside or rescind
merger or reorganization; restraining order or injunction; conditions

     (a)  No shareholder of a corporation who has a right under this chapter to
demand payment of cash for the shares held by the shareholder shall have any
right at law or in equity to attack the validity of the reorganization or short-
form merger, or to have the reorganization or short-form merger set aside or
rescinded, except in an action to test whether the number of shares required to
authorize or approve the reorganization have been legally voted in favor
thereof; but any holder of shares of a class whose terms and provisions
specifically set forth the amount to be paid in respect to them in the event of
a reorganization or short-form merger is entitled to payment in accordance with
those terms and provisions or, if the principal terms of the reorganization are
approved pursuant to subdivision (b) of Section 1202, is entitled to payment in
accordance with the terms and provisions of the approved reorganization.

     (b)  If one of the parties to a reorganization or short-form merger is
directly or indirectly controlled by, or under common control with, another
party to the reorganization or short-form merger, subdivision (a) shall not
apply to any shareholder of such party who has not demanded payment of cash for
such shareholder's shares pursuant to this chapter; but if the shareholder
institutes any action to attack the validity of the reorganization or short-form
merger or to have the reorganization or short-form merger set aside or
rescinded, the shareholder shall not thereafter have any right to demand payment
of cash for the shareholder's shares pursuant to this chapter. The court in any
action attacking the validity of the reorganization or short-form merger or to
have the reorganization or short-form merger set aside or rescinded shall not
restrain or enjoin the consummation of the transaction except upon 10 days'
prior notice to the corporation and upon a determination by the court that
clearly no other remedy will adequately protect the complaining shareholder or
the class of shareholders of which such shareholder is a member.

     (c)  If one of the parties to a reorganization or short-form merger is
directly or indirectly controlled by, or under common control with, another
party to the reorganization or short-form merger, in any action to attack the
validity of the reorganization or short-form merger or to have the
reorganization or short-form merger aside or rescinded, (1) a party to a
reorganization

                                      B-6
<PAGE>

or short-form merger which controls another party to the reorganization or
short-form merger shall have the burden of proving that the transaction is just
and reasonable as to shareholders of the controlled party, and (2) a person who
controls two or more parties to a reorganization shall have the burden of
proving that this transaction is just and reasonable as to the shareholders of
any party so controlled.

October 11, 2000
The Board of Directors of
Real Goods Trading Corporation

Dear Sirs:

We understand that Real Goods Trading Corporation (the "Company" hereinafter)
intends to enter into an agreement to merge with and into Gaiam, Inc. ("Gaiam"
hereinafter) whereby the Company's shareholders will receive consideration of
 .100 shares of Gaiam Class A common stock for each share of common stock of the
Company (the "Exchange Ratio"), plus a certificate good for $1.00 of Gaiam
merchandise (the "Certificates") per each Company common share, with a maximum
of $100.00 for each shareholder.  Such transaction and other related
transactions disclosed to Houlihan Lokey are referred to collectively herein as
the "Transaction."  The Exchange Ratio shall be valid if the 30-day average
closing price of Gaiam's Class A common stock is between $12.00 and $22.00 per
share.  If the closing price of Gaiam's Class A common stock falls outside this
range, the Exchange Ratio can be adjusted or the Transaction can be cancelled by
the adversely affected party.

You have requested our opinion (the "Opinion") as to the matters set forth
below.  The Opinion does not address the Company's underlying business decision
to effect the Transaction.  We have not been requested to, and did not, solicit
third party indications of interest in acquiring all or any part of the Company.
Furthermore, at your request, we have not negotiated the Transaction or advised
you with respect to alternatives to it.

In connection with this Opinion, we have made such reviews, analyses and
inquiries as we have deemed necessary and appropriate under the circumstances.
Among other things, we have:

1.  reviewed the Company's audited income statements for the fiscal years ended
    March 31, 1995, 1996, 1997, 1998, 1999 and 2000, and the unaudited financial
    statements for the four months ended July 22, 1999 and 2000, which the
    Company's management has identified as being the most current financial
    statements available;

2.  reviewed Gaiam's audited income statements for the fiscal years ended
    December 31, 1996, 1997, 1998, and 1999, and the unaudited financial
    statements for the six months ended June 30, 1999 and 2000, which Gaiam's
    management has identified as being the most current financial statements
    available;

3.  reviewed a draft dated as of October 4, 2000 of the Merger Agreement between
    Gaiam, Inc. and Real Goods Trading Corporation;

4.  met with certain members of the senior management of the Company and Gaiam
    to discuss the operations, financial condition, future prospects and
    projected operations and performance of the Company and Gaiam;

5.  visited certain business offices of the Company and Gaiam;


                                      C-1
<PAGE>

6.  reviewed forecasts and projections prepared by the Company's management with
    respect to the Company for the years ending March 31, 2001 through March 31,
    2005;

7.  reviewed certain publicly available financial data for the Company and
    Gaiam, and for certain companies that we deem comparable to the Company and
    Gaiam, and publicly available prices and premiums paid in other transactions
    that we considered similar to the Transaction; and

8.  conducted such other studies, analyses and inquiries as we have deemed
    appropriate.

We have relied upon and assumed, without independent verification, that the
financial forecasts and projections provided to us have been reasonably prepared
and reflect the best currently available estimates of the future financial
results and condition of the Company, and that there has been no material change
in the assets, financial condition, business or prospects of the Company since
the date of the most recent financial statements made available to us.  We have
requested financial projections from Gaiam but have not been provided any.

We have not independently verified the accuracy and completeness of the
information supplied to us with respect to the Company and do not assume any
responsibility with respect to it.  We have not made any physical inspection or
independent appraisal of any of the properties or assets of the Company.  Our
opinion is necessarily based on business, economic, market and other conditions
as they exist and can be evaluated by us at the date of this letter.

Based upon the foregoing, and in reliance thereon, it is our opinion that the
consideration to be received by the stockholders of the Company in connection
with the Transaction is fair to them from a financial point of view.

                  INFORMATION NOT REQUIRED IN THE PROSPECTUS

Item 20. Indemnification of Directors and Officers

    Colorado law provides for indemnification of directors, officers and other
employees in certain circumstances (C.R.S. (S) 7-108-102 (1994)) and for the
elimination or limitation of the personal liability for monetary damages of
directors under certain circumstances (C.R.S. (S) 7-108-402 (1994)). The Amended
and Restated Articles of Incorporation of Gaiam eliminates the personal
liability for monetary damages of directors under certain circumstances and
provides indemnification to directors and officers of Gaiam to the fullest
extent permitted by the Colorado Business Corporation Act. Among other things,
these provisions provide indemnification for officers and directors against
liabilities for judgments in and settlements of lawsuits and other proceedings
and for the advance and payment of fees and expenses reasonably incurred by the
director or officer in defense of the lawsuit or proceeding.

    In addition, Gaiam has obtained directors and officers insurance providing
insurance indemnifying certain of Gaiam's directors, officers and employees for
certain liabilities.

Item 22.  Undertakings.

  (a) The undersigned Registrant hereby undertakes:

      (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement:

          (i)  to include any prospectus required by Section 10(a)(3) of the
      Securities Act of 1933;

          (ii) to reflect in the prospectus any facts or events arising after
      the effective date of this Registration Statement (or the most recent
      post-effective amendment thereof) which, individually or in the aggregate,
      represent a fundamental change in the information in this Registration
      Statement. Notwithstanding the foregoing, any increase or decrease in
      volume of securities offered (if the total dollar value of securities
      offered would not exceed that which was registered) and any deviation from
      the low or high end of the estimated maximum offering range may be
      reflected in the form of prospectus filed with the Commission pursuant to
      Rule 424(b) if, in the aggregate, the changes in volume and price
      represent no more than a 20% change in the maximum aggregate offering
      price set forth in the "Calculation of Registration Fee" table in the
      effective registration statement; and



                                     II-2


<PAGE>

          (iii) to include any material information with respect to the plan of
     distribution not previously disclosed in this Registration Statement or any
     material change to such information in this Registration Statement;

     provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if
the registration statement is on Form S-3, Form S-8 or Form F-3 and the
information required to be included in a post-effective amendment by those
paragraphs is contained in periodic reports filed with or furnished to the
Commission by the Registrant pursuant to Section 13 or Section 15(d) of the
Securities Exchange Act of 1934 that are incorporated by reference in this
Registration Statement.

        (2) That, for the purpose of determining any liability under the
    Securities Act of 1933, each such post-effective amendment 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.

        (3) To remove from registration by means of a post-effective amendment
    any of the securities being registered which remain unsold at the
    termination of the offering.

    (b) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act that is incorporated by reference in this Registration
Statement 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 initial bona fide offering thereof.

    (c) The undersigned Registrant hereby undertakes as follows: that prior to
any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
Registrant undertakes that such reoffering prospectus will contain the
information called for by the applicable registration form with respect to
reofferings by persons who may be deemed underwriters, in addition to the
information called for by the other items of the applicable form.

    (d) The Registrant undertakes that every prospectus: (i) that is filed
pursuant to paragraph (c) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Securities Act and is used in
connection with an offering of securities subject to Rule 415, will be filed as
a part of an amendment to the registration statement and will not be used until
such amendment is effective, and that, for purposes of determining any liability
under the Securities Act, each such post-effective amendment shall be deemed to
be a new registration statement relating to the securities offered therein, and
the offering of such securities at the time shall be deemed to be the initial
bona fide offering thereof.

    (e) The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11 or 13 of this Form S-4, within one business day of receipt of
such request, and to send the incorporated documents by first-class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.

    (f) The undersigned Registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

    (g) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the foregoing provisions, or otherwise, the


                                     II-3

<PAGE>

Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities 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 whether such
indemnification by it is against public policy as expressed in the Securities
Act and will be governed by the final adjudication of such issue.
