       QUESTIONS AND ANSWERS ABOUT THE CONVERSION OF THE PREFERRED STOCK

Q: Why is Efficient holding a Special Meeting?

   A: In connection with our acquisition of Flowpoint Corporation from
Cabletron Systems, Inc., we were able to close the acquisition more quickly by
issuing a combination of common stock and non-voting preferred stock, on the
condition that we later convert the preferred stock into common stock. We are
now submitting this proposal to convert the preferred stock into common stock
to the stockholders for approval at this time in order to honor our obligations
to Cabletron.

Q: Why did Efficient issue preferred stock?

   A: Efficient issued preferred stock in connection with the recent
acquisition of Flowpoint Corporation from Cabletron Systems Inc. The reason we
issued preferred stock was to enable Efficient to acquire Flowpoint quickly in
order compete more effectively in the DSL marketplace. In connection with the
acquisition agreement with Cabletron, we agreed that we would hold this special
stockholders meeting to convert their 6,300 shares of preferred stock into
6,300,000 shares of common stock. Additionally, in connection with the
acquisition of Flowpoint, certain stockholders of Efficient which in the
aggregate hold enough shares of Efficient to cause the preferred to convert
into common, agreed with Cabletron, at the time of the acquisition of
Flowpoint, to vote in favor of the conversion proposal. For a description of
the Flowpoint acquisition see "Summary Flowpoint Acquisition".

Q: Why is the preferred stock being converted?

   A: In connection with the acquisition of Flowpoint from Cabletron, Cabletron
agreed to allow Efficient to issue to Cabletron a combination of 7,200,000
shares common stock and 6,300 preferred stock, provided that (i) Cabletron
received assurances that the preferred would convert into common and (ii) the
conversion ratio of the preferred was 1000 to 1. Since certain of our
stockholders provided Cabletron with this assurance, we were able to acquire
Flowpoint quickly. Now, we are simply honoring our obligations to Cabletron to
convert the preferred stock that they hold into common stock.

Q: Why is the conversion ratio of the preferred stock 1000 to 1? Doesn't that
mean Efficient is giving shares away?

   A: No. If we had not wanted to acquire Flowpoint quickly, we would have
simply issued an aggregate of 13,500,000 shares of common stock to Cabletron.
Instead, we issued 7,200,000 shares of common stock and 6,300 shares of
preferred stock, convertible into 6,300,000 shares of common stock, to
Cabletron in exchange for Flowpoint. So, the 1000-to-1 conversion exchange
ration simply accounts for the true economics of the Flowpoint acquisition. For
a more detailed description of our capital stock, see "Description of Capital
Stock" at page   .

Q: Why is Efficient not soliciting a proxy from me?

   A: As mentioned above, certain stockholders of Efficient, which in the
aggregate hold enough shares of Efficient to cause the preferred to convert
into common agreed with Cabletron, at the time of the acquisition of Flowpoint,
to vote in favor of the conversion proposal. Thus, we believe that the proposal
will pass without requiring proxies to be solicited.

Q: May I still attend and vote at the Special Meeting?

   A: Yes. As a stockholder of Efficient, you are entitled to attend the
special meeting and vote upon the conversion proposal.

April 12, 2000, at 12:00 p.m., local time, or at any and all continuation(s) or
adjournment(s) thereof, for the purposes set forth herein and in the

and the telephone number is (972) 852-1000.

   This Information Statement was mailed on or about March 21, 2000 to all
stockholders entitled to vote at the Annual Meeting.

                         INFORMATION CONCERNING VOTING

Purpose of the Special Meeting

   The purpose of the Special Meeting is to approve the conversion of 6,300
shares of outstanding non-voting preferred stock into 6,300,000 shares of
voting common stock.

Record Date and Shares Outstanding

   Stockholders of record at the close of business on February 25, 2000 (the
"Record Date") are entitled to notice of, and to vote at the Special Meeting.
At the Record Date, 48,226,757 shares of the Company's Common Stock were issued
and outstanding. For information regarding security ownership by management and
5% stockholders, see "OTHER INFORMATION--Security Ownership of Certain
Beneficial Owners and Management." The closing price of the Company's Common
Stock on The Nasdaq Stock Market on the last trading day immediately prior to
the Record Date was $138 per share.

Voting and Reasons for No Solicitation

   Each share of Common Stock outstanding on the Record Date will be entitled
to one vote on all matters. The conversion of the preferred stock into common
stock will require the affirmative vote of a majority of the shares of the
Company's outstanding Common Stock on the Record Date (the "Required Vote").

   Proxies are not being solicited because stockholders holding enough shares
to effect the Required Vote have previously entered into voting agreements with
the FlowPoint Acquisition to effect the commissions.

Quorum

   The required quorum for the transaction of business at the Special Meeting
is a majority of the shares of Common Stock outstanding on the Record Date.

                                 PROPOSAL NO. 1

                         CONVERSION OF PREFERRED STOCK

Background Information in connection with the Proposal to convert the
outstanding Preferred Stock into common stock.

   In connection with our acquisition of Flowpoint Corporation from Cabletron
Systems, Inc., we were able to close the acquisition more quickly by issuing a
combination of common stock and non-voting preferred stock, on the condition
that we later convert the preferred stock into common stock. We are submitting
this proposal to the stockholders for approval at this time.

   Some additional information which should be noted in connection with
Proposal No. 1 is that certain stockholders holding the Requisite Vote to
approve Proposal No. 1 have already entered into voting agreements with
Cabletron to effect the conversion of the 6,300 outstanding shares of non-
voting preferred stock into 6,300,000 shares of voting common stock. We want to
emphasize to our stockholders that the ability to initially issue this
preferred stock to Cabletron was advantageous to us since it enabled us to
acquire Flowpoint quickly. In connection with the acquisition of Flowpoint, we
agreed with Cabletron to convert their 6,300 shares of our preferred stock into
6,300,000 shares of common stock as soon as practicable. The acquisition of
Flowpoint, and the various transactions consummated thereby were unanimously
approved by the Board of Directors of Efficient.

   Cabletron Systems, Inc., a holder of 4,176,099 shares of our voting common
stock and 6,300 shares of non-voting preferred stock shares of 11,476,099
common stock, on an as converted basis, has agreed to vote in favor of the
conversion of the preferred stock into common stock. Cabletron is the sole
owner of the preferred stock. However, Cabletron has previously agreed to
certain voting restrictions on its holdings in Efficient. More a more detailed
discussion of these restrictions, see "Description of Capital Stock--Standstill
and Registration Rights" at page  .

Required Vote

   The conversion of the 6,300 shares of outstanding preferred stock into
6,300,000 shares of common stock requires the affirmative vote of a majority of
the shares of common stock outstanding on the Record Date.

Recommendation of the Board of Directors

   The Board of Directors is not soliciting proxies in connection with Proposal
No. 1, however, you should be aware that the directors and their affiliated
entities have entered into voting agreements with Cabletron whereby they have
agreed to vote in favor of the conversion of preferred stock into common stock.

               SUMMARY OF EFFICIENT AND THE FLOWPOINT ACQUISITION

   This summary highlights information contained elsewhere in this information
statement. You should read the entire prospectus carefully.

                            Efficient Networks, Inc.

                                ----------------

   Efficient Networks is a worldwide developer and supplier of high-speed
digital subscriber line customer premises equipment for the high-speed, high-
volume digital communication, or broadband, access market. Digital subscriber
line, or DSL, solutions enable telecommunications and other communication
network service providers to provide high-speed, cost-effective broadband
access services over the existing copper wire telephone infrastructure. We
believe there is significant demand for broadband access, especially among
business users and consumers who have found current solutions to be inadequate
or too expensive. DSL networks generally consist of two core components, one
installed at the network operator's facility--typically referred to as the
central office--and one installed at the customer's home or business. The DSL
equipment installed at the customer premises is generally referred to as
customer premises equipment. We develop and produce DSL customer premises
equipment, and in particular single- and multiple-user DSL customer premises
equipment for small- to medium-size businesses, branch offices of large
corporations and consumers. Our DSL products enable applications such as high-
speed Internet access, electronic commerce, access to computer networks from
remote locations, telecommuting and extensions of corporate networks to branch
offices.

   Business-critical Internet-based applications, such as electronic commerce,
Web browsing and access to computer networks from remote locations for
telecommuters, generate enormous data traffic over the existing communications
infrastructure. The growth in Internet use, increased competition resulting
from domestic and international deregulation, and pressure from alternative
means of providing high-speed, high-volume access services have led both
traditional and new operators of the existing copper telephone wire-based
networks to deploy DSL. DSL technology enables these network service providers
to rely upon the existing copper telephone wire infrastructure to cost-
effectively provide broadband access to most businesses and homes currently
connected by telephone lines.

   In order to offer cost-effective DSL services to end users, network service
providers are actively seeking DSL customer premises equipment solutions that
offer interoperability from the end user's personal computer through the
service provider's networks and which provide for simple and low-cost
installation and maintenance. The products that make up our SpeedStream family
of customer premises equipment satisfy the requirements of network service
providers as they:

 . Enable DSL Deployments. We enable network service providers to rapidly deploy
  DSL services, thereby allowing them to quickly capture market share in
  today's intensely competitive broadband services market. By offering a broad
  product line we can support DSL services targeted at both businesses and
  consumers.

 . Ensure End-To-End Interoperability. Our technology expertise and ongoing
  product development coordination with network equipment vendors, such as ADC
  Telecommunications, Advanced Fibre Communications, Alcatel, Copper Mountain
  Networks, Ericsson, Lucent Technologies, Newbridge Networks, Nokia, Nortel
  Networks and Siemens, and network service providers enable us to ensure
  interoperability between the end user's personal computer and the service
  provider's network.

 . Provide for Efficient and Cost-Effective Installation. The software included
  with many of our products allows a network service provider to pre-configure
  the customer premises equipment to the parameters of a particular network,
  reducing the costs associated with having installers perform these activities
  during each end-user installation. As demand for DSL service grows, pre-
  configuration helps network operators meet their customers' expectations for
  rapid service activation.

                                       4
<PAGE>


 . Provide for Cost-Effective Maintenance. Our Advanced Status software allows a
  network service provider to easily monitor, diagnose and often remotely fix
  the customer's problems quickly, which can substantially reduce the network
  service provider's customer support costs.

   Our objective is to be the leading worldwide provider of high-performance
DSL broadband access customer premises equipment for businesses, remote
offices, telecommuters and consumers. To achieve this goal, we intend to
capitalize on our early market acceptance by network service providers and to
leverage our relationships with network equipment vendors. In addition, we will
continue developing enhancements to our current DSL products and expect to
develop products that are capable of processing both voice and data
communications through the same DSL equipment and network. Also, we intend to
continue to target strategic partnerships and acquisitions to augment our
product offerings, sales channels and worldwide operations. Finally, we plan to
extend our distribution channels to meet the growing demand for broadband
access solutions and increase our brand awareness.

   We sell our products to network equipment vendors and DSL network service
providers. As of December 31, 1999, our products have been deployed by
Ameritech, Bell Atlantic, BellSouth, Covad Communications, Hanaro Telecom, Hong
Kong Telecom, Pacific Bell, Singapore Telecom, Southwestern Bell, and
TeleDanmark, among others, and purchased by several network equipment vendors.
A number of other network service providers have begun to test our customer
premises equipment solutions.

   We were incorporated in Delaware in 1993. Our principal executive offices
are located at 4201 Spring Valley Road, Suite 1200, Dallas, Texas 75244-3666
and our telephone number is (972) 991-3884. Our Website is located at
http://www.efficient.com. Information contained on our Website does not
constitute part of this prospectus.

                             Flowpoint Acquisition

   On December 17, 1999 we completed the acquisition of FlowPoint Corporation,
a wholly-owned subsidiary of Cabletron Systems, Inc., based in Santa Clara,
California, in exchange for a combination of common stock and convertible
preferred stock equal to an aggregate of 13,500,000 shares of our common stock
on an as-converted basis. FlowPoint's primary business is the design,
manufacture and sale of a comprehensive line of advanced broadband routers for
deployment at customer premises. FlowPoint's product line consists of routing
products for use in business-class DSL services. According to the Dell'Oro
Group's November 1999 study of market performance for the first three quarters
of 1999, FlowPoint was the market leader in SDSL and IDSL customer premises
equipment. We now provide the industry's most comprehensive line of DSL
customer premises equipment, including internal and universal serial bus modems
for personal computers, DSL local area network modems, small office and
telecommuter DSL routers, and DSL routers for small businesses and branch
offices. FlowPoint's customers include major incumbent and competitive local
exchange carriers, including Ameritech, Covad and NorthPoint, and several
European incumbent carriers such as British Telecom. FlowPoint also works
closely with a number of Internet service providers offering DSL services to
businesses. FlowPoint recently announced the availability of an integrated
access device that supports both voice and data service delivery over a single
DSL line.

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

   The following discussion should be read in conjunction with the Consolidated
Financial Statements and Notes thereto, as well as the other information
included elsewhere in this Information Statement.

Overview

   We are a worldwide independent developer and supplier of high-speed DSL
customer premises equipment for the broadband access market. Our DSL solutions
enable telecommunications and other network service providers to provide high-
speed, cost-effective broadband access services over the existing copper wire
telephone infrastructure to both business and residential markets. We therefore
focus on developing and producing single- and multiple-user DSL customer
premises equipment for small- to medium-size businesses, branch offices of
large corporations and consumers. Our DSL products enable applications such as
high-speed Internet access, electronic commerce, remote access, telecommuting
and extensions of corporate networks to branch offices.

   We were incorporated in June 1993. From inception through fiscal 1997, we
primarily focused on developing and selling ATM-based products for local area
network, or LAN, applications. ATM, or asynchronous transfer mode, is a widely-
used transmission technology that breaks data down into individual packets with
unique identification and destination addresses and may be used to transmit
data, voice and video within a network. During fiscal 1997 we began to leverage
our ATM, personal computing environment and networking expertise to develop DSL
modem products for high-speed Internet access. Although we continue to sell ATM
LAN products, we have largely discontinued further development efforts on such
products and are currently focusing on our DSL products. We shipped our first
DSL products in the third quarter of fiscal 1998. Our DSL products, which
accounted for less than 3% of net revenues in fiscal 1998, represented 87.1% of
our net revenues in fiscal 1999 and 98.5% of our net revenues in the first two
quarters of fiscal 2000. We expect sales of our ATM LAN products to continue to
gradually decrease in absolute amount over the next one to two years, and to
decrease substantially as a percentage of net revenues during that time.

   We derive our revenues from sales of our SpeedStream family of DSL products
and, to a lesser extent, our ATM LAN products. We sell our DSL products
primarily to network service providers, network equipment vendors and telephone
company-aligned distributors. For the six months ended December 31, 1999, sales
to four customers, American Communications Supply, Inc., a distributor for
Southwestern Bell, America Online, Inc., Innotrac Corporation, a distributor
for BellSouth, and Covad Communications Group Inc. each represented more than
10% of our net revenues. Our top ten customers for the six months ended
December 31, 1999 accounted for 83.0% of our net revenues. For the fiscal year
ended June 30, 1999, Covad Communications represented 29.6% of our net
revenues, and Soon Cabling Pte, Ltd., a distributor for Daewoo Telecom
represented 17.5% of our net revenues. Our top ten customers in fiscal 1999
accounted for 82.3% of our net revenues. For the fiscal year ended June 30,
1998, Victron, a manufacturer for Xylan, represented 19.6% of our net revenues,
and Telecom Equipment, a distributor for Singapore Telecom, represented 12.6%
of our net revenues. We expect to continue to be dependent upon a relatively
small number of large customers in future periods, although the specific
customers may vary from period to period.

   Since inception, a substantial portion of our revenues has been derived from
customers located outside of the United States and we expect this trend to
continue. Revenues derived from customers outside the United States represented
52% of our net revenues in fiscal 1998, 41% of our net revenues for fiscal 1999
and 22% of our net revenues for the six months ended December 31, 1999. We
currently maintain a European sales office in Amsterdam and an Asian sales
office in Singapore. We believe that in order to continue growing and attain
profitability, we must continue to penetrate international markets.
Accordingly, we will need to expand our international operations and hire
qualified personnel for these operations.

   To date, international sales have been denominated solely in U.S. dollars
and, accordingly, we have not been exposed to fluctuations in non-U.S. currency
exchange rates. In the future, a portion of our international

                                       8
<PAGE>

sales may be denominated in currencies other than U.S. dollars, which would
then expose us to gains and losses based upon exchange rate fluctuations.

   The gross margins on our DSL products have been below the levels that our
business has historically achieved. The lower gross margins on our DSL products
have been a result of manufacturing start-up costs and volume discounts given
to quickly introduce products into the market. Other factors that will affect
our gross margin include the product mix sold in any particular period,
distribution channels, competitive pressures and levels of volume discounts.

   Our limited operating history in the DSL market makes it difficult to
forecast our future operating results. To date, we have not achieved
profitability in any quarter or annual period, and as of December 31, 1999, we
had an accumulated deficit of $80.1 million. Although our net revenues have
grown in recent quarters, we cannot be certain that our net revenues will
increase at a rate sufficient to achieve and maintain profitability.

   For the fiscal years 1997, 1998 and 1999 and for the six months ended
December 31, 1999, we recorded an aggregate of $21.7 million in deferred stock
option compensation. This amount represents the difference between the exercise
price of certain stock options granted during such periods and the deemed fair
market value of our common stock at the time of such option grants. We are
amortizing the deferred stock option compensation over the vesting periods of
the applicable options, which is generally four years. We amortized deferred
stock option compensation in the amounts of $659,000, $1.2 million, $3.1
million and $2.6 million in fiscal years 1997, 1998, 1999 and the six months
ended December 31, 1999, respectively. We expect to amortize the remaining
deferred stock option compensation at the rate of approximately $1.2 million
per quarter until fully amortized.

Recent Development--FlowPoint Acquisition

   On November 21, 1999, we entered into an agreement with Cabletron Systems,
Inc. to acquire its wholly-owned subsidiary FlowPoint Corporation from
Cabletron. The acquisition was completed on December 17, 1999, and is being
accounted for under the purchase method of accounting.

   We paid for the acquisition of FlowPoint through the issuance of 7,200,000
shares of our common stock and 6,300 shares of our Series A non-voting
redeemable convertible preferred stock. The Series A preferred stock is
convertible into an aggregate of 6,300,000 shares of our common stock. See
"Description of Capital Stock" for a more complete description of the Series A
redeemable convertible preferred stock.

   The shares issued to Cabletron for FlowPoint were worth $924.8 million based
upon the market price of $68.50, which represents Efficient's average closing
sale price for two trading days before and two trading days after the terms of
the acquisition were agreed to.

Recent Development--Follow-on Offering

   On February 8, 2000, we completed a follow-on public offering. We issued
2.75 million shares of common stock in exchange for net proceeds of
approximately $182.8 million, after deduction of the underwriters' discount and
expenses.

Recent Development--Convertible Debt Offering

   On March 7, 2000, Efficient completed the private placement of $400,000,000
in aggregate principal amount of its 5% Convertible Subordinated Notes due
March 15, 2005. The conversion price for the notes is initially $181.00.
Efficient intends to use the net proceeds of the offering primarily for general
corporate purposes including working capital and sales and marketing efforts.

</TABLE>

Three and Six Months Ended December 31, 1998 and 1999

Net Revenues

   Net revenues consist of product sales, net of allowances for returns. Net
revenues increased 1,328% to $26.4 million for the quarter ended December 31,
1999 from $1.9 million for the comparable quarter in 1998. Net revenues
increased 1,176% to $38.6 million for the six months ended December 31, 1999
from $3.0 million for the comparable period in 1998. DSL product revenues
increased to $26.1 million for the quarter ended December 31, 1999 compared to
$1.6 million for the quarter ended December 31, 1998. DSL product revenues
increased to $37.9 million for the six months ended December 31, 1999 compared
to $2.0 million for the six months ended December 31, 1998. The increase in DSL
product revenues for the quarter and six months ended December 31, 1999
reflects the continued market adoption of our DSL products, as well as the
addition of new products to the Company's DSL product line. Revenues in the
December 1999 quarter also benefited from the acquisition in December 1999 of
FlowPoint. Flowpoint contributed $3.0 million to revenues in the quarter. Net
revenues exclude $3.4 million of deferred revenues primarily related to
shipments of product to customers where title and risk of ownership has passed
to the customer, but revenue recognition has been deferred for accounting
purposes due to certain stock balancing and return rights granted to the
customer.

Cost of Revenues

   Cost of revenues consists of amounts paid to third-party contract
manufacturers and the personnel and related costs of our manufacturing
operation. Cost of revenues increased 1,188% to $21.2 million, or 80.3% of net
revenues, for the quarter ended December 31, 1999 from $1.6 million, or 89.0%
of net revenues, for the quarter ended December 31, 1998. Cost of revenues
increased 1,211.8% to $32.9 million, or 85.3% of net revenues, for the six
months ended December 31, 1999 from $2.5 million, or 83.0% of net revenues, for
the six months ended December 31, 1998. The increase from the quarter and six
months ended December 31, 1998 to the comparable period in 1999 reflected the
increase in DSL product sales.

                                       10
<PAGE>

   Gross margin represented 19.7% of net revenues for the quarter ended
December 31, 1999, compared to 11.0% of net revenues for the same period in
1998. Gross margin represented 14.7% of net revenues for the six months ended
December 31,1999, compared to 17.0% of net revenues for the same period in
1998. The 1999 amounts are not comparable to the 1998 amounts due to the shift
from ATM LAN products to DSL products. For the quarter ended December 31, 1999,
our gross margin improved from the gross margin achieved in the quarter ended
September 30, 1999 due to manufacturing and other cost efficiencies associated
with higher production volumes and a change in contract manufacturer. Included
in cost of revenues for the six months ended December 31, 1999 are $1.0 million
of one-time costs associated with a change in Efficient's contract
manufacturer. Excluding these one-time costs, the gross margin for the six
months ended December 31, 1999 would have been 17.3%. Although an improvement
has been achieved in the current period, gross margin continued to be adversely
affected by our efforts to bring our DSL products to market quickly and as we
continued to add personnel to our manufacturing operations in anticipation of
higher levels of business going forward. We took a number of actions that were
designed to bring our DSL products to market quickly, but which also adversely
affected our gross margins. These actions included initial volume price
discounts for key customers and incremental costs such as manufacturing start-
up, expedite and other incremental shipping and handling charges associated
with low volume manufacturing. We expect that we will continue to incur higher
than normal costs associated with the actions to bring our DSL products to
market quickly.

Sales and Marketing Expenses

   Sales and marketing expenses consist primarily of employee salaries,
commissions and benefits, advertising, promotional materials and trade show
exhibit expenses. Sales and marketing expenses increased 272% to $4.8 million
for the quarter ended December 31, 1999, up from $1.3 million for the same
period in 1998. Sales and marketing expenses increased 203.6% to $7.5 million
for the six months ended December 31, 1999, up from $2.5 million for the same
period in 1998. The increase in sales and marketing expenses resulted from
expanded sales and marketing activities associated with our DSL products. These
costs included significant personnel-related expenses associated with
increasing the size of our sales and marketing organization, and increased
trade show activities and related travel expenses. Sales and marketing expenses
represented 18.4% of net revenues for the quarter ended December 31, 1999, and
70.4% of net revenues for the quarter ended December 31, 1998. Sales and
marketing expenses represented 19.4% of net revenues for the six months ended
December 31, 1999, and 81.7% of net revenues for the six months ended December
31, 1998. The decrease in sales and marketing expenses as a percentage of net
revenues for the quarter and six months ended December 31, 1999 compared to the
same period in 1998 was a result of the increase in DSL revenues. We expect
sales and marketing expenses to increase in dollar amount in future periods as
we continue to expand our domestic and international sales and marketing
organization.

Research and Development Expenses

   Research and development expenses consist primarily of personnel and related
costs associated with our product development efforts, including third-party
consulting and prototyping costs. Research and development expenses increased
141% to $4.3 million for the quarter ended December 31, 1999, up from $1.8
million for the quarter ended December 31, 1998. Research and development
expenses increased 103.8% to $7.4 million for the six months ended December 31,
1999, up from $3.6 million for the six months ended December 31, 1998. The
increase in research and development spending was primarily a result of
increased personnel and related costs associated with an expanded research and
development organization in connection with our DSL products. Research and
development expenses represented 16.3% of net revenues for the quarter ended
December 31, 1999 compared to 96.8% of net revenues for the quarter ended
December 31, 1998. Research and development expenses represented 19.1% of net
revenues for the six months ended December 31, 1999 compared to 119.6% of net
revenues for the six months ended December 31, 1998. The decrease in research
and development expenses as a percentage of net revenues for the quarter and
six months ended December 31, 1999 compared to the same period in 1998 was a
result of the rapid increase in DSL revenues. We expect research and
development expenses to increase in dollar amount in future periods as we
continue to expand our research and development organization to develop new
products and technologies.

General and Administrative Expenses

   General and administrative expenses consist primarily of employee salaries
and related expenses for executive, administrative and accounting personnel,
facility costs, insurance costs and professional fees. General and
administrative expenses increased 212% to $1.3 million for the quarter ended
December 31, 1999, up from approximately $411,000 for the same period in 1998.
General and administrative expenses increased 210.7% to $2.3 million for the
six months ended December 31, 1999, up from approximately $750,000 for the same
period in 1998. The increases in general and administrative spending were
primarily a result of increases in headcount associated with building our
infrastructure. General and administrative expenses represented 4.9% of net
revenues for the quarter ended December 31, 1999, compared to 22.2% of net
revenues for the quarter ended December 31, 1998. General and administrative
expenses represented 6.0% of net revenues for the six months ended December 31,
1999, compared to 24.8% of net revenues for the six months ended December 31,
1998. The decrease in general and administrative expenses as a percentage of
net revenues for the quarter and six months ended December 31, 1999 compared to
the same period in 1998 was a result of the increase in DSL revenues. We expect
general and administrative expenses to increase in dollar amount in future
periods as we continue to build our infrastructure and as a result of operating
as a publicly-held company.

Stock Option Compensation

   Stock option compensation reflects the difference between the exercise price
of stock options granted and the deemed fair market value of our common stock
on the dates of grant. Amortization of deferred stock option compensation was
$1.2 million and $2.6 million for the quarter and six months ended December 31,
1999, respectively, compared to approximately $475,000 and $908,000 for the
quarter and six months ended December 31, 1998, respectively. We expect to
amortize the deferred stock option compensation at the rate of approximately
$1.2 million per quarter until fully amortized. Prior to our initial public
offering on July 15, 1999, there was no market for our common stock, and option
prices were determined by the Board of Directors based upon numerous factors.
Upon review in connection with our initial public offering, it was determined
that the fair market value on the date of grant of certain options was higher
than originally determined by the Board of Directors. Beginning with our
initial public offering, we began pricing options based upon the public market
price of our common stock, and do not anticipate accruing additional deferred
stock option compensation in future periods.

Amortization of Intangibles and In Process Research and Development

   Amortization of intangibles represents amortization of the intangible assets
recorded in connection with the FlowPoint acquisition. Efficient recorded
$924.5 million in intangible assets, of which $7.4 million was amortized in the
quarter ended December 31, 1999. The remainder will be amortized at the rate of
approximately $46.2 million per quarter over a five year period. In the quarter
ended December 31, 1999, we also recorded a one-time write-off of $5.0 million
of in process research and development incurred in connection with the
FlowPoint acquisition.

Interest and Other Income (Expense), Net

   Interest income consists primarily of interest earned on cash and cash
equivalents. Interest income increased for the quarter and six months ended
December 31, 1999 from the quarter and six months ended December 31, 1998, as a
result of interest earned primarily from the net cash proceeds received in
connection with the completion of our initial public offering on July 15, 1999.
In future periods we expect interest and other income (expense), net to vary
depending upon changes in the amount and mix of interest-bearing investments
and short and long-term debt outstanding during each period.

Income Taxes

   From inception through December 31, 1999, we incurred net losses for federal
and state tax purposes and have not recognized any tax provision or benefit. We
have significant federal net operating loss carryforwards

                                       12
<PAGE>

to offset future taxable income which will begin to expire in varying amounts
beginning in 2008. Given our limited operating history, losses incurred to date
and the difficulty in accurately forecasting our future results, management
does not believe that the recognition of the related deferred income tax asset
meets the criteria required by generally accepted accounting principles.
Accordingly, a 100% valuation allowance has been recorded. Furthermore, as a
result of changes in Efficient's equity ownership resulting from Efficient's
redeemable convertible preferred stock and note financings and Efficient's
initial public offering, utilization of the net operating losses and tax
credits may be subject to substantial annual limitations due to the ownership
change limitations provided by the Internal Revenue Code of 1986, as amended,
and similar state provisions. The annual limitation may result in the
expiration of net operating losses and tax credits before utilization.

Fiscal Years Ended June 30, 1997, 1998 and 1999

Net Revenues

   Net revenues increased 340.0% to $14.8 million in fiscal 1999 from $3.4
million in fiscal 1998. Net revenues in fiscal 1998 reflected a 18.2% decrease
from the $4.1 million realized in fiscal 1997. DSL product revenues, which
didn't exist in fiscal 1997, increased from $84,000 in fiscal 1998 to $12.9
million in fiscal 1999. The increases in DSL product revenues from fiscal 1998
to fiscal 1999 reflect the beginning market adoption of our DSL products, which
first became available in the quarter ended March 31, 1998. The increase in DSL
product revenues was partially offset by a decrease in revenues from our ATM
LAN products. During fiscal 1997, we made the strategic decision to begin
focusing on developing our DSL products and, as a result, significantly reduced
the level of development and support activities associated with our ATM LAN
products. As a result of this change in focus, ATM LAN product revenues
declined from $4.1 million in fiscal 1997 to $3.3 million in fiscal 1998, and
further declined to $1.9 million in fiscal 1999. From fiscal 1997 to fiscal
1998, this decrease was only slightly offset by sales of prototype DSL products
that began in the second half of fiscal 1998.

Cost of Revenues

   Cost of revenues increased 564.1% to $14.3 million in fiscal 1999 from $2.2
million in fiscal 1998. This compares to a decrease of 9.5% for fiscal 1998 as
compared to the $2.4 million in cost of sales incurred in fiscal 1997. The
increase from fiscal 1998 to fiscal 1999 reflected the substantial increase in
DSL product sales. The decrease from 1997 to 1998 reflected the declining sales
of our ATM LAN products.

   Gross margin represented 3.3% of net revenues in fiscal 1999, compared to
35.9% of net revenues in fiscal 1998 and 42.1% of net revenues in fiscal 1997.
Gross margin on our DSL products increased from a gross loss of 22.6% of the
related revenues in fiscal 1998 to a gross loss of 3.6% of the related revenues
for fiscal 1999. Our gross margin was lower in the current period as we focused
on bringing our DSL products to market quickly and as we began to add personnel
to our manufacturing operations in anticipation of higher levels of business
going forward. We took a number of actions that were designed to bring our DSL
products to market quickly but which also adversely affected our gross margins.
These actions included initial volume price discounts for key customers and
incremental costs such as manufacturing start-up, expedite and other
incremental shipping and handling charges associated with initial low volume
manufacturing. We expect that we will continue to incur higher than normal
costs associated with the actions to bring our DSL products to market quickly
through at least the end of calendar 1999. The higher costs incurred on our DSL
products were partially offset by improved gross margins realized on our ATM
LAN products. Gross margin on our ATM LAN products improved from 42.1% of
related revenues in fiscal 1997 to 37.4% in fiscal 1998 and to 49.5% in fiscal
1999. The period-to-period increase in gross margins on our ATM LAN products
was a result of manufacturing efficiencies achieved with these more mature
products.

Sales and Marketing Expense

   Sales and marketing expenses increased 78.5% from $3.4 million in fiscal
1998 to $6.1 million in fiscal 1999. This compares to an increase of 42.6% in
fiscal 1998 over the $2.4 million recorded in fiscal 1997. The

                                       13
<PAGE>

increases in sales and marketing expenses in absolute amount from fiscal 1997
through fiscal 1999 resulted primarily from sales and marketing activities
associated with the launch of our DSL products. These launch costs included
significant personnel-related expenses associated with increasing the size of
our sales and marketing organization, and increased trade show activities and
related travel expenses. Sales and marketing expenses represented 58.4% of net
revenues in fiscal 1997, 102.0% in fiscal 1998 and 41.4% in fiscal 1999. The
increase in sales and marketing expenses as a percentage of net revenues from
fiscal 1997 to 1998 was primarily a result of the up-front spending required to
launch our DSL products, which only began to constitute a significant portion
of our revenues in fiscal 1999. The decrease in such expenses as a percentage
of net revenues from fiscal 1998 to fiscal 1999 was a result of the rapid
increase in revenues.

Research and Development Expenses

   Research and development expenses increased 76.5% from $4.4 million in
fiscal 1998 to $7.7 million in fiscal 1999. This compares to an increase of
4.9% in fiscal 1998 over the $4.2 million recorded in fiscal 1997. The
substantial increase in research and development spending from period to period
was primarily a result of increased personnel and related costs associated with
a larger research and development organization, as well as design and prototype
expenses incurred in connection with the roll-out of our DSL products.
Additionally, research and development spending in fiscal 1998 was partially
offset by $850,000 of nonrecurring engineering expenses reimbursed by third
parties. These amounts are treated as an offset to the related research and
development spending. Accordingly, while the net amount of research and
development spending in fiscal 1998 was relatively consistent with the fiscal
1997 level, our gross research and development spending increased 25.2% from
fiscal 1997 to 1998. We received no such reimbursements in the fiscal 1999
period. Research and development expenses represented 101.5% of net revenues in
fiscal 1997, 130.2% in fiscal 1998 and 52.2% in fiscal 1999. The substantial
increases in research and development expenses as a percentage of net revenues
from fiscal 1997 to 1998 reflected our early investment in developing our DSL
products. The decrease from 1998 to 1999 in such expenses as a percentage of
net revenues was a result of the rapid increase in revenues.

General and Administrative Expenses

   General and administrative expenses increased 21.5% from $1.6 million in
fiscal 1998 to $2.0 million in fiscal 1999. This compares to an increase of
31.8% in fiscal 1998 over the $1.2 million recorded in fiscal 1997. The
increases in absolute amount of general and administrative spending from period
to period were primarily a result of increases in headcount associated with
building our infrastructure. General and administrative expenses represented
30.2% of net revenues in fiscal 1997, 48.7% in fiscal 1998 and 13.4% in fiscal
1999. The substantial increase in general and administrative expenses as a
percentage of net revenues in fiscal 1998 primarily reflected lower revenues in
that year, while the decrease from fiscal 1998 to fiscal 1999 reflected the
rapid increase in revenues in fiscal 1999.

Stock Option Compensation

   For the years ended June 30, 1997, 1998 and 1999 we recorded aggregate
deferred stock option compensation of $2.3 million, $3.1 million and $13.1
million, respectively in connection with stock option grants. Amortization of
deferred stock option compensation was $659,000 in fiscal 1997, $1.2 million in
fiscal 1998 and $3.1 million in fiscal 1999. See Note 8 of Notes to
Consolidated Financial Statements for a discussion of our deferred stock option
compensation.

Interest and Other Income (Expense), Net

   Interest and other income (expense), net went from income of $125,000 in
fiscal 1997 to $130,000 in fiscal 1998 and to an expense of $7.9 million in
fiscal 1999. In the second half of fiscal 1999, we borrowed $9.0 million from
certain investors. These notes carried an interest rate of 10% per year, and
were payable on the earlier of January 2002 or the completion of an initial
public offering. In connection with these notes, we

                                       14
<PAGE>

issued the investors warrants to purchase 3,082,191 shares of Series H
preferred stock at an exercise price of $2.92 per share. The proceeds were
allocated between the notes and the warrants based on their pro rata fair
values resulting in a discount. The discount was amortized as interest expense
over six months, which represented the expected terms of the promissory notes.
In addition, in June 1999, we borrowed an additional $5.0 million from Covad
Communications Group, Inc. The Covad note carried an interest rate of 8% per
year, and the principal amount and interest on the note converted into an
aggregate of 497,663 shares of common stock upon completion of our initial
public offering in July 1999. Upon the issuance of the Covad note we recorded
$2.1 million of interest expense which represented the intrinsic value of the
beneficial conversion feature of the Covad note.

Income Taxes

   From inception through June 30, 1999, we incurred net losses for federal and
state tax purposes and have not recognized any tax provision or benefit. As of
June 30, 1999, we had approximately $48.0 million of federal net operating loss
carryforwards to offset future taxable income which will begin to expire in
varying amounts beginning in 2008. Given our limited operating history, losses
incurred to date and the difficulty in accurately forecasting our future
results, management does not believe that the recognition of the related
deferred income tax asset meets the criteria required by generally accepted
accounting principles. Accordingly, a 100% valuation allowance has been
recorded. Furthermore, as a result of changes in Efficient's equity ownership
resulting from Efficient's redeemable convertible preferred stock and note
financings and Efficient's initial public offering, utilization of the net
operating losses and tax credits may be subject to substantial annual
limitations due to the ownership change limitations provided by the Internal
Revenue Code of 1986, as amended, and similar state provisions. The annual
limitation may result in the expiration of net operating losses and tax credits
before utilization. See Note 11 of Notes to Consolidated Financial Statements.

Quarterly Results of Operations

   The following table sets forth, for the periods presented, certain data from
Efficient's consolidated statement of operations and such data as a percentage
of net revenues. The consolidated statement of operations data have been
derived from our unaudited consolidated financial statements. In the opinion of
management, these statements have been prepared on substantially the same basis
as the audited consolidated financial statements and include all adjustments,
consisting only of normal recurring adjustments, necessary for a fair
presentation of the financial information for the periods presented. This
information should be read in conjunction with the Consolidated Financial
Statements and Notes thereto included elsewhere in this prospectus. The
operating results in any quarter are not necessarily indicative of the results
that may be expected for any future period. We have incurred net losses in each
quarter since inception, and we expect to continue to incur losses for the
foreseeable future.

   Our net revenues and results of operations have fluctuated significantly
from quarter to quarter in the past, and we expect these fluctuations to
continue in the future. The following discussion highlights significant events
that have impacted our net revenues and financial results for the ten quarters
in the period ended December 31, 1999.

Net Revenues

   Net revenues increased each quarter beginning in the quarter ended June 30,
1998 due to increased sales of our new DSL products, partially offset in two
quarters by decreased revenues from our ATM LAN products. Sales of our DSL
products have increased significantly quarter to quarter since we introduced
them in the third quarter of fiscal 1998. Net revenues increased in the first
three quarters of fiscal 1998 as demand for our ATM LAN products was
increasing. With the decision to focus on DSL products, we greatly reduced our
sales, marketing and development efforts for our ATM LAN products. As a result,
sales of these products began to decline in the fourth quarter of fiscal 1998.

Cost of Revenues

   Cost of revenues has increased in absolute dollars in most quarterly
periods. Gross margins have fluctuated from a high of 50.4% in the second
quarter of fiscal 1998 to a gross loss of 1.8% for the quarter ended March 31,
1999. Gross margins have been adversely affected by volume price discounts for
customers in order to get our DSL products quickly into the marketplace as well
as manufacturing start-up costs and inefficiencies related to the relatively
low manufacturing levels for some of our DSL products.

Operating Expenses

   Operating expenses generally increased in absolute amount from quarter to
quarter during fiscal 1998 and 1999. As a percentage of net revenues, these
expenses fluctuated, in some periods significantly, as a result of the
fluctuations in revenues.

Interest and Other Income (Expense), Net

   Interest and other income (expense), net has varied from quarter to quarter,
based primarily upon changes in the amount and mix of interest-bearing
investments outstanding during each period. In the quarter ended December 31,
1999, interest and other income (expense), net was income of $666,000. This was
a result of interest income of $1.3 million earned on the investment of
proceeds from our initial public offering, partially offset by interest expense
of $675,000 related to the notes and warrants converted to common stock in that
period.

Liquidity and Capital Resources

   Since inception, we have financed our operations primarily through the sale
of preferred equity securities and, in the second half of fiscal 1999, through
borrowings from our investors and others. Since inception through June 30,
1999, we raised an aggregate of $40.4 million (net of transaction expenses)
from the sale of equity securities and an additional $14.0 million through loan
transactions.

   On July 15, 1999, we completed our initial public offering. We issued 4.6
million shares of common stock and raised $63.1 million in net proceeds. Upon
the completion of the initial public offering, our promissory notes converted
into redeemable convertible preferred stock, and all outstanding redeemable
convertible preferred stock then converted into 28,300,067 shares of common
stock.

   At December 31, 1999, we had cash and cash equivalents and highly liquid
short-term investments of $35.8 million. At December 31, 1999, we did not have
a line of credit or other borrowing facility available, nor did we have any
material capital commitments. Future capital commitments include a lease for
office space,

                                       17
<PAGE>

furniture and equipment for our new corporate headquarters in Dallas, Texas.
The lease commenced in February 2000 and expires in 2010 with annual lease
payments of approximately $2.8 million.

   Cash used in operating activities for the six months ended December 31,
1999 was $39.2 million. Cash used in operating activities has primarily
represented net investments in working capital and funding of our net losses.

   Cash used in investing activities for the six months ended December 31,
1999 was $4.0 million. Of this amount, $4.0 million of cash was used to
purchase highly liquid short-term investments and $2.9 million of cash was
used to purchase fixed assets, which was offset by cash received of $10.9
million in connection with the acquisition of FlowPoint. In each period,
purchases of furniture and equipment related primarily to the purchase of
computers and other equipment used in our development activities and other
equipment and furniture used in our operations.

   Cash provided by financing activities for the six months ended December 31,
1999 was $63.4 million, consisting primarily of funds raised from our initial
public offering of common stock on July 15, 1999.

   On February 8, 2000, we completed a follow-on public offering. We issued
2.75 million shares of common stock in exchange for net proceeds of
approximately $182.8 million, after deduction of the underwriters' discount
and expenses.

   Our future capital requirements will depend upon a number of factors,
including the rate of growth of our sales, the timing and level of research
and development activities and sales and marketing campaigns. We believe that
our cash, cash equivalents and short-term investments and the proceeds from
this offering will provide sufficient capital to fund our operations at least
through the end of calendar 2000. Thereafter, we may require additional
capital to fund our business. In addition, from time to time we may evaluate
opportunities to acquire complementary technologies or companies. Should we
identify any such opportunities, we may need to raise additional capital to
fund the acquisitions. There can be no assurance that financing will be
available to us when we need it on favorable terms or at all.

Year 2000 Issues

   The year 2000 issues arise from the fact that many currently installed
computer systems, software products and other control devices are unable to
accept four digit entries to distinguish 21st century dates from 20th century
dates.

   Through February 25, 2000, we have not experienced any significant issues
associated with year 2000 issues.

   We have designed our products to be year 2000 compliant and have not
detected any errors or defects associated with year 2000 date functions to
date.

   Further, the internal systems used to deliver our services utilize third-
party hardware and software. Prior to year end, we completed an internal
systems and processes review for year 2000 compliance and we completed our
assessment of the year 2000 risks we might encounter, and all identified
instances of noncompliance were repaired and tested. We contacted the vendors
of these products in order to gauge their year 2000 compliance. Based on these
vendors' representations, we believe that the third-party hardware and
software we use are year 2000 compliant. We have not experienced any
significant year 2000 issues associated with third-party hardware and
software.

Recent Accounting Pronouncements

   In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivatives and
Hedging Activities," ("SFAS No. 133") as amended by Statement of Financial
Accounting Standards No. 137, "Accounting for Derivative Instruments and
Hedging Activities--Deferral of the Effective Date of FASB Statement No. 133,"
which establishes accounting and

                                      18
<PAGE>

reporting standards of derivative instruments, including certain derivative
instruments embedded in other contracts, and for hedging activities. SFAS No.
133, as amended, is effective for fiscal years beginning after June 15, 2000.
The adoption of Statement of Financial Accounting Standards No. 133 is not
expected to have a material effect on our results of operations, financial
position or cash flows as we do not currently hold derivative instruments or
engage in hedging activities.

Disclosures About Market Risk

   The following discusses our exposure to market risk related to changes in
interest rates, equity prices and foreign currency exchange rates. This
discussion contains forward-looking statements that are subject to risks and
uncertainties. Actual results could vary materially as a result of a number of
factors including those set forth in the Risk Factors section.

   As of December 31, 1999, we had short-term investments of $4.0 million. All
of these short-term investments consisted of highly liquid investments with
remaining maturities at the date of purchase of less than 90 days. These
investments are subject to interest rate risk and will decrease in value if
market interest rates increase. A hypothetical increase or decrease in market
interest rates by 10% from the December 31, 1999 rates would cause the fair
value of these short-term investments to change by an insignificant amount. We
have the ability to hold these investments until maturity, and therefore we do
not expect the value of these investments to be affected to any significant
degree by the effect of a sudden change in market interest rates. Declines in
interest rates over time will, however, reduce our interest income.

   As of December 31, 1999, we did not own any equity investments. Therefore,
we did not have any direct equity price risk.

   Substantially all of our revenues are currently realized in U.S. dollars. In
addition, we do not maintain significant asset or cash account balances in
currencies other than the United States dollar. Therefore, we do not believe
that we currently have any significant direct foreign currency exchange rate
risk.

                          DESCRIPTION OF CAPITAL STOCK

General

   We are authorized to issue 200,000,000 shares of common stock, $0.001 par
value, and 10,000,000 shares of undesignated preferred stock, $0.001 par value.
The following description of our capital stock is subject to and qualified in
its entirety by our certificate of incorporation and bylaws, and by the
provisions of applicable Delaware law.

Common Stock

   As of December 31, 1999, there were 51,156,248 shares of common stock
outstanding after giving pro forma effect to the conversion of all outstanding
shares of Series A non-voting convertible redeemable preferred stock issued to
Cabletron. These shares were held of record by approximately 156 stockholders.

   The holders of common stock are entitled to one vote per share on all
matters to be voted upon by the stockholders. Subject to preferences that may
be applicable to any outstanding preferred stock, the holders of common stock
are entitled to receive ratably such dividends, if any, as may be declared from
time to time by the board of directors out of funds legally available for that
purpose. See "Dividend Policy." In the event of a liquidation, dissolution or
winding up of Efficient, the holders of common stock are entitled to share
ratably in all assets remaining after payment of liabilities, subject to prior
distribution rights of preferred stock, if any, then outstanding. The holders
of common stock have no preemptive or conversion rights or other subscription
rights. There are no redemption or sinking fund provisions applicable to the
common stock. Wilson Sonsini Goodrich & Rosati, Professional Corporation,
counsel to Efficient, shall opine that the shares of common stock to be issued
upon the closing of this offering, when issued and sold in the manner described
in this prospectus and in accordance with the resolutions adopted by the board
of directors, will be fully paid and nonassessable.

Preferred Stock

   The board of directors has the authority, without action by the
stockholders, to designate and issue preferred stock in one or more series and
to designate the rights, preferences and privileges of each series, which may
be greater than the rights of the common stock. It is not possible to state the
actual effect of the issuance of any shares of preferred stock upon the rights
of holders of the common stock until the board of directors determines the
specific rights of the holders of such preferred stock. However, the effects
might include, among other things:

  . restricting dividends on the common stock;

  . diluting the voting power of the common stock;

  . impairing the liquidation rights of the common stock; or

  . delaying or preventing a change in control of Efficient without further
    action by the stockholders.

Series A Non-Voting Convertible Preferred Stock

   In connection with the acquisition of Flowpoint Corporation from Cabletron,
the Board of Directors designated an aggregate of 6,300 shares of preferred
stock as "Series A Non-Voting Convertible Preferred Stock." The following is a
summary of the rights, preferences, privileges and restrictions of Series A
Preferred:

  . Voting. The Series A Preferred is non-voting. However, without the
    consent of holders of at least 66% of the Series A Preferred, Efficient
    may not: (a) alter the rights of the Series A Preferred; (b) create any
    securities that rank on a parity with or senior to the Series A Preferred
    as to dividends or distribution of assets upon liquidation; or (c)
    increase or decrease the number of shares of preferred stock authorized.

                                       22
<PAGE>

  . Dividends. Each share of Series A Preferred is entitled to receive
    dividends, when and if declared by the Board of Directors, at least equal
    in amount to the dividends declared on the common stock, multiplied by
    the conversion ratio of the Series A Preferred. Dividends are not
    mandatory or cumulative.

  . Liquidation. In the event of a liquidation of Efficient, the holders of
    the Series A Preferred are entitled to receive the par value of such
    shares in preference to the holders of common stock, and thereafter share
    on a pro rata basis with the common stock, treating the Series A
    Preferred as if converted into common stock.

  . Automatic Conversion. The Series A Preferred automatically converts into
    common stock, at the rate of 1,000 shares of common stock for each share
    of Series A Preferred (subject to adjustment for stock splits and the
    like), immediately following the affirmative vote of such conversion by
    holders of a majority of our common stock.

  . Redemption. In the event that the Series A Preferred has not converted
    into common stock on or before July 21, 2000, one fifth of the Series A
    Preferred shall be redeemed on each of December 31, 2000, 2001, 2002,
    2003, and 2004. The redemption price of the Series A Preferred is
    approximately $78,000 per share.

   It is the mutual intention and understanding of Efficient and Cabletron
that Efficient will hold a special meeting of stockholders. Holders of a
majority of Efficient's common stock have entered into Voting Agreements
pursuant to which they have agreed to vote in favor of conversion of the
Series A Preferred into common stock. The special meeting is expected to be
held in early 2000.

Warrants

   At September 30, 1999, there were warrants outstanding to purchase 34,246
shares of our common stock.


Standstill and Registration Rights

   On December 17, 1999, pursuant to an Agreement and Plan of Reorganization,
Efficient completed the acquisition of FlowPoint Corporation, a wholly-owned
subsidiary of Cabletron, in exchange for a combination of common stock and
preferred stock equal to an aggregate of 13,500,000 shares of common stock on
an as-converted basis. In connection with this transaction, Efficient and
Cabletron also entered into a Standstill and Disposition Agreement containing
certain standstill provisions, voting provisions, restrictions on transfer,
and registration rights.

   The standstill provisions contained in the Standstill and Disposition
Agreement provide that, without the prior consent of Efficient's board,
Cabletron may not:

  . acquire additional shares of Efficient;

  . solicit proxies or participate in an election contest;

  . act in concert with others to acquire, hold or dispose of Efficient
    stock;

  . seek to elect or replace members of Efficient's board;

  . seek to control management, the board, or policies of Efficient;

  . pursue a business combination with Efficient;

  . coordinate with any third person to form a business combination with
    Efficient;

  . coordinate with any third person in connection with a tender offer for
    voting securities of Efficient; and

  . assist, participate, solicit or encourage any third party to do any of
    the above.

                                      23
<PAGE>

   The voting provisions contained in the Standstill and Disposition Agreement
provide that on matters requiring the vote of Efficient stockholders, Cabletron
must vote shares in excess of 10% of the voting stock of Efficient in
proportion with the vote of other stockholders of Efficient. However, Cabletron
must vote all voting shares which it owns proportionately with respect to:

  . any transaction between Efficient and one or more person in which
    Cabletron controls a 5% equity interest; or

  . a change of control of Efficient with any of the top five data networking
    companies, from time to time, as measured by revenues.

   The standstill and voting provisions will terminate if and when Cabletron
owns less than 5% of the voting securities of Efficient or upon a change of
control of Efficient.

   The restrictions on transfer provisions contained in the Standstill and
Disposition Agreement provide that, without the prior consent of Efficient's
board, Cabletron may not sell, transfer, or otherwise dispose of Efficient
stock, except:

  . to a controlled affiliate of Cabletron;

  . in connection with a firm commitment, underwritten public offering;

  . pursuant to Rule 144 or the shelf registration statement, except in
    certain circumstances;

  . in a private sale if, after giving effect to the sale, the purchaser
    would own more than 5% of the voting stock of Efficient, unless the
    purchaser is a passive investor in which case the amount may be up to 10%
    of the voting stock of Efficient; and

  . in response to a tender offer which is not opposed by Efficient's board.

   The restriction on transfer provisions will terminate if and when Cabletron
owns less than 5% of the voting securities of Efficient, or upon a change of
control of Efficient, or November 2009.

   The registration rights provisions contained in the Standstill and
Disposition Agreement provide that, in addition to the shares to which
Cabletron is entitled to include in this offering:

  . by July 21, 2000, Efficient shall use commercially reasonable efforts to
    file a shelf registration statement so that Cabletron may sell shares on
    a continuous basis, however, Cabletron may not sell greater than 2
    million shares pursuant to this registration statement and Rule 144;

  . after July 21, 2000, Cabletron shall be entitled to two demand
    registrations as long as the demand is for 2 million shares or more;

  . if Efficient determines to commence any public offering after this
    offering before December 31, 2000, Cabletron shall be entitled to include
    the greater of 40% of the shares to be sold in the offering or 3 million
    shares;

  . Cabletron shall also be entitled to the same registration rights held by
    other stockholders of Efficient stock, as described in the following
    paragraph; and

  . expenses of registration, other than underwriting discounts and
    commissions, will be borne by us.

   In addition to the specific registration rights of Cabletron described
above, which are senior, the holders of approximately 27.5 million shares of
common stock and Cabletron are entitled to certain registration rights.
Beginning on December 31, 2000, the holders of at least 50% of the then
outstanding registrable securities may require:

  . on up to two occasions, that we register their shares for public resale;

                                       24
<PAGE>

  . on one occasion within any twelve month period, that we register their
    shares for public resale on Form S-3 or similar short-form registration
    if the value of the securities to be registered is at least $1.0 million;
    and

  . include their shares of common stock in a registration in which we elect
    to register shares of common stock of Efficient, but we may reduce the
    number of shares proposed to be registered in view of market conditions
    to an amount not less than 30% of the shares in the offering.

   All expenses incurred in connection with any registration, other than
underwriting discounts and commissions attributable to registrable securities,
will be borne by us. These registration rights will terminate in July 2005 or,
with respect to each holder of registrable securities, at such time as the
holder is entitled to sell all of its shares in any three-month period under
Rule 144(k) of the Securities Act.

Delaware Anti-Takeover Law and Certain Charter and Bylaw Provisions

   Certain provisions of Delaware law and our certificate of incorporation and
bylaws could make the following transactions more difficult:

  . the acquisition of Efficient by means of a tender offer;

  .  the acquisition of Efficient by means of a proxy contest or otherwise;
     or

  .  the removal of our incumbent officers and directors.

   These provisions, summarized below, are expected to discourage certain types
of coercive takeover practices and inadequate takeover bids. These provisions
are also designed to encourage persons seeking to acquire control of Efficient
to first negotiate with our board of directors. We believe that the benefits of
our increased ability to negotiate with the proponent of an unfriendly or
unsolicited proposal to acquire or restructure Efficient outweigh the
disadvantages of discouraging such proposals as negotiation of such proposals
could result in an improvement of their terms.

   Election and Removal of Directors. Our board of directors is divided into
three classes. The directors in each class will serve for a three-year term,
one class being elected each year by our stockholders. See "Management--
Executive Officers and Directors." This system of electing and removing
directors may tend to discourage a third party from making a tender offer or
otherwise attempting to obtain control of Efficient because it generally makes
it more difficult for stockholders to replace a majority of the directors.

   Stockholder Meetings. Under our bylaws, only our board of directors,
Chairman of the Board and President may call special meetings of stockholders.

   Requirements for Advance Notification of Stockholder Nominations and
Proposals. Our bylaws establish advance notice procedures with respect to
stockholder proposals and the nomination of candidates for election as
directors, other than nominations made by or at the direction of the board of
directors or a committee of the board.

   Delaware Anti-Takeover Law. We are subject to Section 203 of the Delaware
General Corporation Law, an anti-takeover law. In general, Section 203
prohibits a publicly held Delaware corporation from engaging in a "business
combination" with an "interested stockholder" for a period of three years
following the date the person became an interested stockholder, unless the
"business combination" or the transaction in which the person became an
interested stockholder is approved in a prescribed manner. Generally, a
"business combination" includes a merger, asset or stock sale, or other
transaction resulting in a financial benefit to the interested stockholder.
Generally, an "interested stockholder" is a person who, together with
affiliates and associates, owns or within three years prior to the
determination of interested stockholder status, did own, 15% or more of a
corporation's voting stock. The existence of this provision may have an anti-
takeover effect with respect to transactions not approved in advance by our
board of directors, including discouraging attempts that might result in a
premium over the market price for the shares of common stock held by
stockholders.

                                       25
<PAGE>

   Elimination of Stockholder Action By Written Consent. Our certificate of
incorporation eliminates the right of stockholders to act by written consent
without a meeting.

   Elimination of Cumulative Voting. Our certificate of incorporation and
bylaws do not provide for cumulative voting in the election of directors.

   Undesignated Preferred Stock. The authorization of undesignated preferred
stock makes it possible for the board of directors to issue preferred stock
with voting or other rights or preferences that could impede the success of any
attempt to change control of Efficient. These and other provisions may have the
effect of deterring hostile takeovers or delaying changes in control or
management of Efficient.

   Amendment of Charter Provisions. The amendment of any of the above
provisions would require approval by holders of at least 66 2/3% of the
outstanding common stock.

Transfer Agent and Registrar

   The transfer agent and registrar for the common stock is Harris Trust and
Savings Bank.

The Nasdaq Stock Market Listing

   Our shares have been approved for listing on The Nasdaq Stock Market under
the symbol "EFNT."

                          Independent Auditors' Report

The Board of Directors
Efficient Networks, Inc.:

   We have audited the accompanying consolidated balance sheets of Efficient
Networks, Inc. and subsidiaries as of June 30, 1998 and 1999, and the related
consolidated statements of operations, stockholders' equity (deficit), and cash
flows for each of the years in the three-year period ended June 30, 1999. These
consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.

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

   In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Efficient
Networks, Inc. and subsidiaries as of June 30, 1998 and 1999, and the results
of their operations and their cash flows for each of the years in the three-
year period ended June 30, 1999, in conformity with generally accepted
accounting principles.

                   Notes to Consolidated Financial Statements

                          June 30, 1997, 1998 and 1999

(1)Incorporation and Nature of Business

  Efficient Networks, Inc. (the "Company") was incorporated under the laws of
  the State of Delaware on June 10, 1993. The Company is a worldwide
  developer and supplier of high speed digital subscriber line customer
  premises equipment for the high speed, high volume digital communication,
  or broadband, access market.

(2)Summary of Significant Accounting Policies

  (a)Principles of Consolidation

    The consolidated financial statements include the accounts of the
    Company and its wholly-owned subsidiaries located in The Netherlands
    and Singapore. All significant intercompany accounts and transactions
    have been eliminated in consolidation.

  (b)Cash Equivalents

    Cash equivalents consist primarily of an investment account comprised
    of investments in commercial paper, repurchase agreements and money
    market funds. For purposes of the statements of cash flows, the Company
    considers all highly liquid investments with original maturities of
    three months or less to be cash equivalents.

  (c)Inventories

    Inventories are stated at the lower of average cost or market (net
    realizable value).

  (d)Furniture and Equipment

    Furniture and equipment are stated at cost. Equipment under capital
    leases is stated at the present value of minimum lease payments.

    Depreciation on plant and equipment is calculated on the straight-line
    method over the estimated useful lives of the assets. Plant and
    equipment held under capital leases and leasehold improvements are
    amortized on a straight-line basis over the shorter of the lease term
    or estimated useful life of the asset. The estimated useful lives are
    as follows:

</TABLE>

  (e)Income Taxes

    Income taxes are accounted for under the asset and liability method.
    Deferred tax assets and liabilities are recognized for the future tax
    consequences attributable to differences between the financial
    statement carrying amounts of existing assets and liabilities and their
    respective tax bases and operating loss and tax credit carryforwards.
    Deferred tax assets and liabilities are measured using enacted tax
    rates expected to apply to taxable income in the years in which those
    temporary

            Notes to Consolidated Financial Statements--(continued)

                          June 30, 1997, 1998 and 1999

    differences are expected to be recovered or settled. The effect on
    deferred tax assets and liabilities of a change in tax rates is
    recognized in income in the period that includes the enactment date.

  (f)Revenue Recognition

    Revenue from product sales is recognized upon shipment to the customer.
    Reserves for estimated sales returns and allowances are recorded in the
    same period as the related revenues. Revenue related to sales
    transactions that provide a customer with the right to return product
    is deferred until the product is deployed by the customer and/or the
    return privileges expire.

  (g)Stock-Based Compensation

    The Company applies the intrinsic value-based method of accounting
    prescribed by Accounting Principles Board ("APB") Opinion No. 25,
    Accounting for Stock Issued to Employees, and related interpretations,
    in accounting for its fixed plan stock options. As such, compensation
    expense is recorded on the date of grant only if the current market
    price of the underlying stock exceeds the exercise price.

  (h)Impairment of Long-Lived Assets and Long-Lived Assets to Be Disposed

    Long-lived assets and certain identifiable intangibles are reviewed for
    impairment whenever events or changes in circumstances indicate that
    the carrying amount of an asset may not be recoverable. Recoverability
    of assets to be held and used is measured by a comparison of the
    carrying amount of an asset to future net cash flows expected to be
    generated by the asset. Assets to be disposed of are reported at the
    lower of the carrying amount or fair value less costs to sell.

  (i)Net Loss Per Share of Common Stock

    Net loss per share of common stock is presented in accordance with the
    provisions of Statement of Financial Accounting Standards ("SFAS") No.
    128, Earnings Per Share. Under SFAS No. 128, basic earnings/loss per
    share excludes dilution for potentially dilutive securities and is
    computed by dividing income or loss available to common stockholders by
    the weighted average number of common shares outstanding during the
    period. Diluted earnings/loss per share reflects the potential dilution
    that could occur if securities or other contracts to issue common stock
    were exercised or converted into common stock. Potentially dilutive
    securities are excluded from the computation of diluted earnings/loss
    per share when their inclusion would be antidilutive. The computation
    of basic and diluted weighted average shares is as follows (in
    thousands):

            Notes to Consolidated Financial Statements--(continued)

                          June 30, 1997, 1998 and 1999


    Pro forma basic and diluted net loss per share has been calculated
    assuming: (a) the conversion of redeemable convertible preferred stock
    outstanding at June 30, 1999, as if the redeemable convertible
    preferred stock had converted immediately upon its issuance, resulting
    in 23,332,713 additional weighted average shares of common stock
    outstanding; (b) the warrants issued in 1999 in connection with the
    issuance of subordinated promissory notes were exercised immediately
    upon their issuance using the principal amount of the notes to satisfy
    the exercise price, resulting in 1,113,014 additional weighted average
    shares of common stock outstanding and a charge of $603,806 against
    earnings for the accretion of the remaining discount recorded on the
    notes; and (c) the convertible debt issued June 28, 1999, was converted
    immediately upon issuance resulting in 2,727 additional weighted
    average shares of common stock outstanding.

  (j)Fair Value of Financial Instruments

    The carrying values of cash equivalents, accounts receivable and
    accounts payable approximate fair value due to their short maturities.
    The fair values of the Company's convertible promissory notes and
    subordinated promissory notes and related warrants were determined
    using a valuation model with the following assumptions: a volatility
    factor of 40% obtained from the stock price volatility experienced by

    rate of 5.71%; the contractual term of the respective notes; the
    estimated fair value of the Company's common stock ($12.00 at June 30,

    presentation of comprehensive income and its components in the
    financial statements. Comprehensive income includes all changes in
    equity during a period except those resulting from investments by and
    distributions to owners. To date, no elements of comprehensive income
    exist other than net loss from operations.

(6)Long-term Debt

  In January 1999, the Company issued subordinated promissory notes with
  detachable warrants in exchange for $7,000,000 in cash. In April 1999, the
  Company issued a subordinated promissory note with a detachable warrant in
  exchange for $2,000,000 in cash. The notes bear interest of 10% per year
  and interest is payable quarterly. The notes are due at the earlier of
  January 2002 or (a) a consummation of a qualifying liquidation event which
  includes a firm commitment underwritten offering pursuant to a registration
  statement under the Securities Act of 1933, the public offering price of
  which is not less than $5.00 per share and $10,000,000 in the aggregate;
  (b) any consolidation or merger of the Company with or into any other
  corporation or corporations; (c) sale, conveyance or disposition of all or
  substantially all of the assets of the Company; or (d) the effectuation by
  the Company of a transaction or series of related transactions in which
  more than 50% of the voting power of the Company is disposed.

  The subordinated promissory notes were issued with detachable warrants to
  purchase an aggregate of 3,082,191 shares of the Company's Series H
  redeemable convertible preferred stock at an exercise price of $2.92 per
  share. The warrants expire at the earlier of January 2002 or the
  consummation by the Company of the sale of its common stock in a firm
  commitment underwritten offering at a price not less than $5.00 per share
  and providing not less than $10,000,000 of net proceeds. The proceeds were
  allocated between the notes and the warrants based on their pro-rata fair
  values, as determined using a valuation model (see note 2(j)). As a result,
  the warrants were valued at $6,172,699. This amount was recorded as paid-in
  capital. The resulting discount on the notes is being accreted as interest
  expense over the expected term of the related promissory notes. The holders
  of the subordinated promissory notes have entered into a note repayment and
  warrant exercise agreement with the Company which stipulates that
  immediately prior to the closing of an initial public offering, the
  aggregate $9,000,000 principal amount of the notes will be applied toward
  the aggregate exercise price of the detachable warrants (see note 13).

  On June 28, 1999, the Company issued a convertible promissory note in
  exchange for $5,000,000 in cash. The note bears interest of 8.0% per year.
  The holder of the note has the right to demand prepayment of 50% of the
  principal amount of the note at any time after the first anniversary and
  full prepayment at any time after the second anniversary of issuance. The
  note is convertible at the holder's option into shares of Series I
  preferred stock at a conversion price of $10.09 per share of Series I
  preferred stock. Upon the completion of an initial public offering, the
  note will automatically convert into Series I preferred stock at a
  conversion price equal to the lesser of (1) 70% of the initial public
  offering price per share or (2) $10.09 per share. Upon the issuance of the
  convertible promissory note, the Company recognized $2,143,000 of interest
  expense and a corresponding increase to additional paid-in capital. This
  amount represents the intrinsic value of the beneficial conversion feature
  of the convertible promissory note (see note 13).

(7)Redeemable Convertible Preferred Stock

  Preferred stock has voting rights equal to the number of shares of common
  stock into which the preferred stock is convertible. The preferred stock is
  convertible at the option of the holder into such number of shares of
  common stock as is determined by dividing the original issue price of the
  preferred stock plus all declared but unpaid dividends by the applicable
  conversion price at the date of conversion. The conversion price per share
  is the original issue price adjusted for any dilution that may occur from
  future offerings.

  Each share of outstanding preferred stock is required to convert to common
  stock upon the earlier of the time of the Company's initial public
  offering, if certain offering parameters are met, or the date on which

  the Company obtains the consent of the holders of a majority of the then
  outstanding shares of preferred stock.

  The outstanding preferred stock is redeemable into cash at the request of a
  majority of the holders of the then outstanding shares of preferred stock
  at an amount equal to the original issue price plus all declared but unpaid
  dividends. Amounts due to the preferred shareholders on redemption are
  payable in three equal annual installments on the fifth, sixth and seventh
  anniversaries of the original purchase dates (see note 13).

  Dividends may be declared at the sole discretion of the Board of Directors
  and are noncumulative. To date, no such dividends have been declared. The
  holders of the preferred stock are entitled to a liquidation preference
  equivalent to the original issue price of the respective series of
  preferred stock plus declared but unpaid dividends.

  The following indicates the series of redeemable convertible preferred
  stock in existence at June 30, 1999. Series for which preferred stock has
  been issued and remains outstanding are stated at the redemption amount;
  issuance costs are netted against the proceeds and accreted as a charge
  against additional paid-in capital over the expected life of the related
  series of preferred stock (all in thousands, except share and per share

  issued an additional 1,850,000 shares of Series G redeemable convertible
  preferred stock for $5,402,000 in cash (see note 13).

(8)Common Stock and Stock Incentive Plans

  In 1993, the Company adopted a stock option plan (the "Plan") pursuant to
  which the Company's Board of Directors may grant stock options to officers,
  directors and key employees. The Plan authorizes grants of options to
  purchase up to 10,000,000 shares of unissued common stock. The Board of
  Directors determines the terms of each option, including exercise price
  (within limits set forth in the plan), number of shares and the rate at
  which each option is exercisable. The options generally vest ratably over a
  period of four years from the date of grant.

  In 1998, the Company adopted the Directors' Stock Option Plan (the
  "Directors' Plan") pursuant to which stock options may be granted to non-
  employee members of the Company's Board of Directors. The Directors' Plan
  authorizes grants of options to purchase up to 275,000 shares of common
  stock.

  Option grants under the Directors' Plan are nondiscretionary and automatic.
  Non-employee directors serving on the Company's board of directors at the
  date of the adoption of the Directors' Plan were granted options to
  purchase 50,000 shares on the effective date of the plan. Subsequent non-
  employee directors are granted an option to purchase 15,000 shares on the
  date they become a director. After their initial grant, non-employee
  directors are granted an option to purchase 15,000 shares on January 1 of
  each year provided they have served on the board for at least six months.
  At June 30, 1999, there were options to purchase 75,000 shares available
  for grant under the Directors' Plan.

  At June 30, 1999, there were options to purchase 2,369,853 shares available
  for grant under both plans. The per share weighted-average fair value of
  stock options granted during each of the years ended June 30, 1997, 1998
  and 1999 was $2.09, $2.60, and $5.17, respectively, on the date of grant as
  estimated using the minimum value option-pricing model with the following
  weighted-average assumptions in all years: expected dividend yield of 0.0%,
  an expected life of four years, and a risk-free interest rate of 6%.

  The Company applies APB Opinion No. 25 in accounting for stock options
  granted to employees and non-employee directors under its stock option
  plans. The Company recorded $2,269,000, $3,143,000 and $13,130,000 of
  deferred stock option compensation during each of the years ended June 30,
  1997, 1998 and 1999, respectively, as a result of granting stock options
  with exercise prices below the estimated fair value per share of the
  Company's common stock at the date of grant. Deferred stock option
  compensation has been recorded as a component of stockholders' equity
  (deficit) and is being amortized as a charge to operations over the vesting
  period of the applicable options. Amortization of deferred stock option
  compensation of $659,000, $1,165,000 and $3,116,000 was recognized in the
  years ended June 30, 1997, 1998 and 1999, respectively.

  Had the Company determined compensation cost based on the estimated fair

</TABLE>

  Pro forma net loss reflects only stock options granted after June 30, 1995.
  Therefore, the full impact of calculating compensation cost for stock
  options under SFAS No. 123 is not reflected in the pro forma net loss
  amounts presented above because compensation cost is reflected over the
  options' vesting periods of four years and compensation expense pertaining
  to stock options granted in prior periods is not considered.

  Stock option activity for both plans during the periods indicated is as

</TABLE>

  The net change in the valuation allowance for the years ended June 30, 1998
  and 1999 was $3,073,000 and $8,133,000 respectively.

  As of June 30, 1999, the Company has net operating loss carryforwards of
  approximately $48,000,000 which begin to expire in 2008. The Company
  believes that as a result of the Company's initial public offering in July
  1999, and the resulting conversion of outstanding redeemable preferred
  stock into common stock, the Company has undergone an ownership change
  within the meaning of section 382 of the Internal Revenue Code (IRC). As a
  result, the Company's ability to utilize its operating loss carryforwards
  incurred prior to the ownership change are limited on an annual basis to an
  amount equal to the value of the Company, as defined by the IRC, as of the
  date of change of ownership, multiplied by the long-term tax-exempt rate of
  4.98%.

(12)Segment Information and Concentration of Credit Risk

  The Company operates in one reportable segment as it has one family of DSL
  products and markets its products to network equipment vendors and DSL
  service providers. In fiscal years 1997 and 1998, the Company also
  developed and marketed asynchronous transfer mode ("ATM") network products
  which are no longer actively marketed by the Company. For management
  purposes, the Company does not disaggregate financial information by
  product or geographically, other than export sales by region and sales by
  product. Substantially all of the Company's assets are located within the
  United States. The Company does not account for, and does not report to
  management, its assets or capital expenditures by revenue source. All of
  the Company's products are produced in the United States. The Company
  grants credit to customers located in several geographical regions in North
  America, Europe and the Pacific Rim.

  require collateral.

(13)Subsequent Event

  On July 15, 1999, the Company completed the initial public offering of its
  common stock. The Company issued 4,600,000 shares of common stock in
  exchange for gross proceeds of $69,000,000, net of underwriters' discount
  of $4,830,000. Upon the completion of the initial public offering, the
  Company's subordinated promissory notes converted into 3,082,191 shares of
  Series H redeemable convertible preferred stock, the convertible promissory
  note plus accrued interest converted into 497,663 shares of Series I
  redeemable convertible preferred stock, and all outstanding redeemable
  convertible preferred stock converted into 28,300,067 shares of common
  stock.

  On July 20, 1999, the Company adopted a new stock option plan (the "Stock
  Plan") and an employee stock purchase plan. The Stock Plan provides for the
  granting of stock options and stock purchase rights to employees and
  consultants. A total of 3,500,000 shares of common stock has been reserved
  for issuance plus annual increases equal to the lesser of:

  .  1,000,000 shares;

  .  3% of the outstanding shares on such a date; or

  .  a lesser amount determined by the board on the first day of each fiscal
     year.

  The Stock Plan may be administered by the board of directors or a committee
  of the board. The board or a committee of the board will have the power to
  determine the terms of the options granted, including the exercise price,
  the number of shares subject to each option, the vesting provisions, the
  exercisability thereof and the form of consideration payable upon such
  exercise.

  The Stock Plan provides that in the event of a merger of the Company with
  or into another corporation, or the sale of substantially all of its
  assets, each outstanding option or stock purchase right will be assumed

                                      F-17

                          June 30, 1997, 1998 and 1999

  or substituted for by the successor corporation. In addition, if the
  options are not substituted for in the merger, each outstanding option will
  vest and become exercisable as to all unvested shares and each stock
  purchase right shall lapse as to all the shares for a period of 15 days
  after receipt of notice from the Company.

  On July 20, 1999, the Company also adopted an Employee Stock Purchase Plan
  ("the Purchase Plan"). A total of 200,000 shares of common stock has been
  reserved for issuance under the purchase plan, plus annual increases equal
  to the lesser of:

  .  100,000 shares;

  .  1% of the outstanding shares on such a date; or

  .  a lesser amount determined by the board on the first day of each fiscal
     year.

  The Purchase Plan, which is intended to qualify under Section 423 of the
  Internal Revenue Code of 1986, as amended, contains successive six-month
  offering periods. The offering periods generally start on the first trading
  day on or after May 1 and November 1 of each year, except for the first
  such offering period which commenced on the first trading day after the
  effective date of the Company's initial public offering and ends on the
  last trading day on or before October 31.

  Employees are eligible to participate if they are employed by the Company
  or any of its participating subsidiaries for at least 20 hours per week and
  more than five months in any calendar year. However, the following
  employees may not purchase stock under the Purchase Plan:

  .  any employee who immediately after grant owns stock possessing 5% or
     more of the total combined voting power or value of all classes of
     capital stock; or

  .  any employee whose rights to purchase stock under any of the employee
     stock purchase plans accrue at a rate that exceeds $25,000 worth of
     stock for each calendar year.

  Participants may purchase common stock through deductions of up to 10% of
  the participant's compensation. The maximum number of shares a participant
  may purchase during a single offering period is 500 shares.

  Amounts deducted and accumulated by the participant will be used to
  purchase shares of common stock at the end of each offering period. The
  price of stock purchased under the Purchase Plan is 85% of the lower of the
  fair market value of the common stock at the beginning of the offering
  period and at the end of each offering period.

  The Purchase Plan provides that, in the event of a merger of the Company
  with or into another corporation or a sale of substantially all of its
  assets, outstanding options may be assumed or substituted for by the
  successor corporation. If the successor corporation refuses to assume or
  substitute for the outstanding options, the offering period then in
  progress will be shortened and a new exercise date will be set, which will
  occur before the proposed sale or merger.

  The Purchase Plan will terminate in 2009. The board of directors has the
  authority to amend or terminate the Purchase Plan, except that no such
  action may adversely affect any outstanding rights to purchase stock.

         Notes to Unaudited Condensed Consolidated Financial Statements

                       Six Months Ended December 31, 1999

(1)Basis of Presentation

  The accompanying unaudited financial data as of and for the three months
  and six months ended December 31, 1999 and 1998 have been prepared by the
  Company, pursuant to the rules and regulations of the Securities and
  Exchange Commission. Certain information and footnote disclosures normally
  included in financial statements prepared in accordance with generally
  accepted accounting principles have been condensed or omitted pursuant to
  such rules and regulations. These unaudited consolidated financial
  statements should be read in conjunction with the audited financial
  statements and the notes thereto included in the Company's Annual Report on
  Form 10-K for the fiscal year ended June 30, 1999.

  In the opinion of management, all adjustments (which include only normal
  recurring adjustments) necessary to present fairly the financial position,
  results of operations, and cash flows as of and for the three months and
  six months ended December 31, 1999 have been made. The results of
  operations for the three months and six months ended December 31, 1999 are
  not necessarily indicative of the operating results for the full year.

(2)Completion of Initial Public Offering

  On July 15, 1999, the Company completed its initial public offering. The
  Company issued 4.6 million shares of common stock in exchange for net
  proceeds of approximately $63.1 million. Upon the completion of the initial
  public offering, certain outstanding subordinated promissory notes
  converted into an aggregate of 3.6 million shares of redeemable convertible
  preferred stock, and all outstanding redeemable convertible preferred stock
  converted into an aggregate of 28.3 million shares of common stock.

(3)Acquisition

  On November 21, 1999, the Company entered into an agreement with Cabletron
  Systems, Inc. ("Cabletron") to acquire its wholly-owned subsidiary
  FlowPoint Corporation ("FlowPoint") from Cabletron. The acquisition was
  completed on December 17, 1999. The results of operations of FlowPoint have
  been included in the Company's consolidated statement of operations from
  the date of acquisition through December 31, 1999.

  The Company financed the acquisition of FlowPoint through the issuance of
  7.2 million shares of common stock and 6,300 shares of Series A non-voting
  redeemable convertible preferred stock. The Series A preferred stock is
  convertible into an aggregate of 6.3 million shares of common stock and is
  mandatorily redeemable.

  The acquisition was accounted for under the purchase method of accounting
  and, accordingly, the purchase price was allocated to the assets acquired
  and liabilities assumed based on the estimated fair values at the date of
  acquisition. The shares issued to Cabletron for FlowPoint had a fair market
  value of $924.8 million based upon the market price of $68.50, which
  represents the Company's average closing sale price for two trading days
  before and two trading days after the terms of the acquisition were agreed
  to.

</TABLE>

  The allocation of acquired technology, assembled workforce, sales channel
  and customer relationships, in process research and development and non-
  compete agreements was based upon an independent valuation. The Company
  wrote off in process research and development immediately upon consummation
  of the acquisition. In addition, in connection with the FlowPoint
  acquisition, the Company recorded $924.5 million in intangible assets, of
  which $7.4 million was amortized in the December quarter and the remainder
  will be amortized at a rate of approximately $46.2 million per quarter over
  a five-year period.

  The following pro forma financial information presents a summary of the
  results of operations as if the acquisition had occurred on July 1, 1998:

</TABLE>

(4)Earnings Per Share

  Basic and diluted earnings (loss) per share has been computed in accordance
  with Statement of Financial Accounting Standards (SFAS) No. 128, "Earnings
  Per Share." Basic earnings per share is computed by dividing income or loss
  by the weighted average number of shares of the Company's common stock
  outstanding during the period. Diluted earnings per share is determined in
  the same manner as basic earnings per share except that the number of
  shares is increased assuming exercise of dilutive stock options and
  warrants using the treasury stock method and conversion of the Company's
  redeemable convertible preferred stock. The diluted earnings per share
  amount is the same as basic earnings per share because the Company has a
  net loss in each of the periods presented and the impact of the assumed
  exercise of the stock options and warrants and the assumed preferred stock
  conversion is antidilutive. Common stock equivalents of 6.5 million and
  27.6 million shares for the three months ended December 31, 1999 and 1998,
  respectively, and 7.7 million and 27.6 million shares for the six months
  ended December 31, 1999 and 1998, respectively, were excluded from the
  calculation of diluted earnings per share because of the antidilutive
  effect.

(7)Deferred revenue

  Deferred revenue of $3.4 million at December 31, 1999 primarily relates to
  shipments of product to customers where title and risk of ownership has
  passed to the customer, but revenue recognition has been deferred for
  accounting purposes due to certain stock balancing and right of return
  privileges granted to the customer. The corresponding receivable of $3.4
  million is included in the accounts receivable balance at December 31,
  1999.

(8)Long-term debt

  In January 1999, the Company issued subordinated promissory notes with
  detachable warrants in exchange for $7.0 million in cash. On April 8, 1999,
  the Company issued a subordinated promissory note with a

  Notes to Unaudited Condensed Consolidated Financial Statements--(continued)

                       Six Months Ended December 31, 1999

  detachable warrant in exchange for $2.0 million in cash. The notes bore
  interest at 10% per annum with interest payable quarterly. The subordinated
  promissory notes were issued with detachable warrants to purchase an
  aggregate of 3.1 million shares of the Company's redeemable convertible
  preferred stock at an exercise price of $2.92 per share. In June 1999, the
  holders of the subordinated promissory notes entered into a note repayment
  and warrant exercise agreement with the Company which stipulated that
  immediately prior to the closing of an initial public offering, the
  aggregate $9.0 million principal amount of the notes would be applied
  toward the aggregate exercise price of the detachable warrants.
  Accordingly, immediately prior to the closing of the Company's initial
  public offering on July 15, 1999, the warrants were exercised to purchase
  the Company's redeemable convertible preferred stock, which shares of
  preferred stock automatically converted into shares of common stock upon
  completion of the initial public offering.

  On June 28, 1999, the Company issued a convertible promissory note in
  exchange for $5.0 million in cash. The note bore interest at 8.0% per
  annum. In accordance with the conversion feature of the note, immediately
  prior to the closing of the Company's initial public offering, the note
  automatically converted into 497,663 shares of preferred stock at a
  conversion price $10.09 per share, and such shares of preferred stock
  automatically converted into shares of common stock upon completion of the
  initial public offering.

(9)Statements of Cash Flows

  The Company paid cash interest of $400,000 and $0 during the six months
  ended December 31, 1999 and 1998, respectively. No income taxes were paid
  during the six months ended December 31, 1999 and 1998. Non-cash financing
  transactions included the exchange of promissory notes of $13.4 million and
  related accrued interest for $14.0 million of redeemable convertible
  preferred stock, and the exchange of redeemable convertible preferred stock
  of $54.5 million for 28.3 million shares of common stock during the six
  months ended December 31, 1999. In connection with the acquisition of
  FlowPoint, the Company exchanged 7.2 million shares of Common Stock and
  6,300 shares of redeemable convertible preferred stock for the assets and
  liabilities of FlowPoint. No non-cash financing transactions occurred
  during the six months ended December 31, 1998.

(10)Completion of Follow-on Public Offering

  On February 8, 2000 the Company completed a follow-on public offering of
  5.75 million shares of common stock. The Company issued 2.75 million shares
  of common stock in exchange for net proceeds of approximately $182.8
  million, after deduction of the underwriters' discount and estimated
  expenses. The selling stockholders sold 3 million shares of common stock.
  The Company did not receive any of the proceeds from the sale of shares by
  the selling stockholders.

          UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

   Effective December 17, 1999, Efficient Networks, Inc. ("Efficient" or the
"Company") completed the acquisition of FlowPoint Corporation ("FlowPoint"),
formerly a wholly-owned subsidiary of Cabletron Systems, Inc. ("Cabletron"), in
exchange for 7,200,000 shares of common stock and 6,300 shares of Series A non-
voting convertible preferred stock ("Series A Preferred"). The Series A
Preferred is convertible into 6,300,000 shares of common stock. The total cost
of the acquisition, including transaction costs, was approximately $937.9
million. The acquisition was accounted for as a purchase business combination.

   Attached is the unaudited pro forma condensed combined statements of
operations for Efficient for the year ended June 30, 1999 and for the six
months ended December 31, 1999, including related notes thereto. The unaudited
pro forma condensed combined balance sheet has not been presented, since as of
December 31, 1999, the acquisition had been consummated and is reflected in the
unaudited condensed consolidated balance sheet included elsewhere in this
offering circular. The unaudited pro forma condensed combined statements of
operations, including the weighted average number of shares used in the
calculation of the pro forma per share data, assume the acquisition had been
consummated on July 1, 1998.

   The unaudited pro forma condensed combined financial information has been
derived from the historical financial statements of the Company and FlowPoint.
The pro forma adjustments and the assumptions on which they are based are
described in the accompanying notes to the unaudited pro forma condensed
combined statements of operations. The unaudited pro forma condensed combined
financial information is based on and should be read in conjunction with the
historical consolidated financial statements and related notes thereto of the
Company and the historical financial statements of FlowPoint. The unaudited pro
forma condensed combined financial results are not necessarily indicative of
the financial position or operating results that would have occurred had the
acquisition been consummated at the beginning of the period for which such
transactions have been given effect, nor of the combined results of future
operations.

    Notes to Unaudited Pro Forma Condensed Combined Statements of Operations

1. The historical statement of operations for the twelve-month period ended
   June 30, 1999 was derived by adding the unaudited historical results of
   operations of FlowPoint for the two months ended August 31, 1998, the
   audited historical results of operations of FlowPoint for the six months
   ended February 28, 1999 and the unaudited historical results of operations
   of FlowPoint for the four months ended June 30, 1999.

2. Represents the adjustment to reflect amortization of the acquired
   intangibles over an amortization period of five years.

3. Represents the exclusion of the one-time impact for the write-off of in-
   process research and development recorded by Cabletron in connection with
   its acquisition of FlowPoint on September 1, 1998.

4. Represents the elimination of FlowPoint's income tax expense.

Efficient recorded an immediate write-off of in-process research and
development of $4,970,000 at the consummation of the purchase business
combination. The unaudited pro forma condensed combined statements of
operations exclude this charge.

                          Independent Auditors' Report

The Board of Directors
Cabletron Systems, Inc.:

   We have audited the accompanying balance sheets of FlowPoint Corporation
(the "Company") as of February 28, 1999, August 31, 1998, and March 31, 1998
and the related statements of operations, cash flows, and stockholder's equity
for the six months ended February 28, 1999, five months ended August 31, 1998,
and the years ended March 31, 1998 and 1997 (as defined in note 2a). These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

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

   In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of the Company as of February
28, 1999, August 31, 1998, and March 31, 1998 and the results of its operations
and its cash flows for the six months ended February 28, 1999, five months
ended August 31, 1998, and the years ended March 31, 1998 and 1997, in
conformity with generally accepted accounting principles.

   As discussed in Note 2(a) to the financial statements, the Company was
acquired by Cabletron Systems, Inc. as of September 1, 1998 in a business
combination accounted for as a purchase. As a result of the application of
purchase accounting, the financial statements of the Company for the six months
ended February 28, 1999 are presented on a different cost basis than those for
periods prior to September 1, 1998, and accordingly, are not directly
comparable.

                             FLOWPOINT CORPORATION

                         Notes to Financial Statements

    (Information as of and for the seven months ended September 30, 1999 is
                                   unaudited)

(1) Business Operations

  FlowPoint Corporation, (the "Company"), develops, manufactures, markets,
  designs, installs and supports a complete line of broadband remote access,
  high-speed corporate and internet access modems and routers primarily
  utilizing digital subscriber line ("DSL") technologies.

(2) Summary of Significant Accounting Policies

  (a) Basis of Presentation

    The financial statements of the Company are derived from its historic
    books and records through August 31, 1998. As a result of the
    acquisition of the Company by Cabletron Systems, Inc. ("Cabletron")
    effective as of September 1, 1998, the financial statements of the
    Company after the acquisition date are derived from the historic books
    and records of Cabletron and reflect the "pushdown" of Cabletron's
    basis in the assets acquired and liabilities assumed.

    As a result of the acquisition by Cabletron and the application of
    purchase accounting, financial information in the accompanying
    financial statements and notes thereto as of and for the six months
    ended February 28, 1999 (the "Successor Period") are presented on a
    different cost basis than the financial information as of August 31,
    1998 and March 31, 1998 and for the five months ended August 31, 1998
    and the years ended March 31, 1998 and 1997 (the "Predecessor Period"),
    and therefore, such information is not comparable.

    The statement of operations includes all revenues and costs directly
    attributable to the Company including charges for shared facilities,
    functions and services used by the Company and provided by Cabletron.
    Certain costs and expenses have been allocated based upon management's
    estimates of the cost of services provided to the Company by Cabletron.
    Such costs include sales support, customer service and technical
    support, and general and administrative expenses (see note 12). Such
    allocations and charges are based on a percentage of total costs for
    the services provided based on factors such as headcount or revenues.
    Management believes that these allocations are based on assumptions
    that are reasonable under the circumstances. However, these allocations
    and estimates are not necessarily indicative of the cost and expenses
    which would have resulted if the Company had been operated as a
    separate entity.

    The Company has historically incurred recurring losses from operations.
    Cabletron has committed to provide the funds required for the conduct
    of the Company's operations up to the date on which it ceases to be the
    controlling shareholder.

  (b) Change in fiscal year

    Prior to its acquisition by Cabletron, the Company's fiscal year end
    was March 31. Upon the acquisition the Company adopted Cabletron's
    February 28 fiscal year end.

  (c) Inventories

    Inventories are stated at the lower of cost or market. Costs are
    determined principally by use of the average-cost method, which
    approximates the first-in, first-out (FIFO) method.

                             FLOWPOINT CORPORATION

                   Notes to Financial Statements--(Continued)

    (Information as of and for the seven months ended September 30, 1999 is
                                   unaudited)

  (d) Property, Plant and Equipment

    Property, plant and equipment are stated at cost. Depreciation is
    provided on a straight-line method over the estimated useful lives of
    the assets. The Company reviews its long-lived assets for impairment
    whenever events or changes in circumstances indicate that the carrying
    amount of an asset may not be recoverable. If it is determined that the
    carrying amount of an asset cannot be fully recovered, an impairment
    loss is recognized.

  (e) Intangible Assets

    Intangible assets consist of goodwill and developed technology
    resulting from the "pushdown" of the fair market value of the
    intangible assets attributable to the Company as recorded on
    Cabletron's books as part of Cabletron's acquisition of the Company.
    Amortization of these intangible assets is provided on a straight-line
    basis over the respective useful lives which range from five to ten
    years. Purchased in-process research and development without
    alternative future use is expensed when acquired. The carrying amount
    of intangible assets is reviewed for impairment whenever events or
    changes in circumstances indicate that the carrying amount of an asset
    may not be recoverable. The measurement of possible impairment is based
    primarily on an evaluation of undiscounted projected cash flows through
    the remaining amortization period.

  (f) Income Taxes

    The Company accounts for income taxes under the asset and liability
    method. Under this method, deferred tax assets and liabilities are
    recognized for the future tax consequences attributable to differences
    between the financial statement carrying amounts of existing assets and
    liabilities and their respective tax bases and operating loss and tax
    credit carryforwards. Deferred tax assets and liabilities are measured
    using enacted tax rates expected to apply to taxable income in the
    years in which those temporary differences are expected to be recovered
    or settled. The effect of a change in tax rates on deferred tax assets
    and liabilities is recognized in income in the period that includes the
    enactment date.

    As a result of its acquisition by Cabletron, the Company is included in
    the consolidated federal income tax return of Cabletron. Income taxes
    in the Company's financial statements subsequent to the acquisition
    have been determined on a separate-return basis.

  (g) Advertising Costs

    Advertising costs of $17,594, $105,547, $308,061, $297,360 and $67,134
    were expensed as incurred during the seven months ended September 30,
    1999, the six months ended February 28, 1999, the five months ended
    August 31, 1998 and the years ended March 31, 1998 and 1997,
    respectively. No assets were recorded related to advertising costs at
    the respective balance sheet dates.

  (h) Statements of Cash Flows

    Cash and cash equivalents consist of cash in banks and short-term
    investments with original maturities of three months or less.

                   Notes to Financial Statements--(Continued)

    (Information as of and for the seven months ended September 30, 1999 is
                                   unaudited)

  (i) Revenue Recognition

    The vast majority of the Company's revenues are related to hardware
    based routers with revenue recognized based upon shipment of the
    products. The Company accrues for estimated warranty costs related to
    product shipments based on historical experience. The Company generates
    an insignificant portion of its revenues from software products and
    records such revenue in accordance with (SOP) 97-2, "Software Revenue
    Recognition".

  (j) Use of Estimates

    The preparation of 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 amounts of revenues
    and expenses during the reporting period. Actual results could differ
    from those estimates.

  (k) Research and Engineering

    Research and engineering costs are charged to expense as incurred.

  (l) Employee Stock Plan

    The Company accounts for its stock option plan in accordance with
    Accounting Principles Board Opinion No. 25 (APB 25), "Accounting for
    Stock Issued to Employees." In 1995, the Financial Accounting Standards
    Board issued SFAS No. 123, "Accounting for Stock-Based Compensation"
    (SFAS 123). SFAS 123 provides an alternative to APB 25 and is effective
    for fiscal years beginning after December 15, 1999. As permitted under
    SFAS 123, the Company continues to account for its stock option plan in
    accordance with the provisions of APB 25 and provides the disclosure
    pro forma net income as if the fair value method under SFAS 123 had
    been applied.

  (m) New Accounting Pronouncements

    In the period ended February 28, 1999, the Company adopted Financial
    Accounting Standards Board Statement No. 130, "Reporting Comprehensive
    Income" (SFAS 130) which establishes standards for reporting and
    display of comprehensive income and its components in a full set of
    financial statements. For the Company, comprehensive income includes
    net income or loss only. The adoption of SFAS 130 did not have any
    impact on the Company's financial statements for any of the periods
    presented.

    In the period ended February 28, 1999, the Company adopted Financial
    Accounting Standards Board Statement No. 131, "Disclosures about
    Segments of an Enterprise and Related Information" (SFAS 131) which
    establishes standards for the way that public business enterprises
    report selected information about operating segments in annual
    financial statements and requires that those enterprises report
    selected information about operating segments in interim financial
    reports to shareholders. It also establishes standards for related
    disclosures about products and services, geographic areas and major
    customers. The adoption of SFAS 131 did not have any impact on the
    Company's financial statement disclosures for the period ended February
    28, 1999.

                   Notes to Financial Statements--(continued)

    (Information as of and for the seven months ended September 30, 1999 is
                                   unaudited)

    In October 1997, the AICPA Accounting Standards Executive Committee
    issued Statement of Position (SOP) 97-2, "Software Revenue Recognition"
    which provides guidance on applying generally accepted accounting
    principles in recognizing revenue for licensing, selling, leasing or
    otherwise marketing computer software and supersedes SOP 91-1. The
    adoption of SOP 97-2 did not have a material impact on the Company's
    results of operations for the period ended February 28, 1999.

  (n) Unaudited Results

    The financial statements as of and for the seven months ended September
    30, 1999 have been prepared using the same accounting principles as
    were used in preparing the audited financial statements and in the
    opinion of management reflect all adjustments, which include only
    normal recurring adjustments, necessary to present fairly the Company's
    financial position, results of operations and cash flows. The results
    for the seven months ended September 30, 1999 are not necessarily
    indicative of future results.

(3) Cabletron Acquisition

  Effective as of September 1, 1999 Cabletron acquired all of the outstanding
  common stock of FlowPoint Corporation, a privately held manufacturer of DSL
  router networking products. Immediately prior to the acquisition each share
  of FlowPoint preferred stock Series A, B, C, and D was converted into one
  share of FlowPoint common stock. Cabletron owned 1,866,667 shares of
  FlowPoint preferred stock (at a cost of approximately $1,700,000), and as a
  result of the preferred stock conversion owned 42.8% of the outstanding
  common stock. Pursuant to the acquisition agreement the amount paid for the
  remaining 57.2% of FlowPoint common stock amounted to approximately
  $20,600,000 to be paid in four installments, within nine months of the
  acquisition date. Each installment could be paid in either cash or
  Cabletron common stock, as determined by Cabletron management at the time
  of the distribution. In addition, Cabletron assumed approximately 478,000
  FlowPoint options, valued at approximately $2,700,000.

  Cabletron recorded the cost of the acquisition at $25,383,306 including
  direct costs of approximately $400,000. The acquisition was accounted for
  under the purchase method of accounting, and, accordingly, the acquired
  assets and liabilities were recorded at their estimated fair market value.
  The total purchase price of $25,383,306 was allocated as follows: a
  $11,953,093 special charge for in process research and development
  ("IPR&D") projects, $14,136,655 for goodwill and other intangibles and net
  liabilities of $706,442.

  The following unaudited pro forma financial information presents a summary
  of the results of operations as if the acquisition had occurred on March 1,
  1998, the first day of the fiscal year ending February 28, 1999.

  The valuation of the IPR&D incorporated the guidance on IPR&D valuation
  methodologies promulgated by the Securities and Exchange Commission
  ("SEC"). These methodologies incorporate the notion that cash flows
  attributable to development efforts, including the effort to be completed
  on the development effort underway, and development of future versions of
  the product that have not yet been undertaken, should be excluded in the
  valuation of IPR&D. This allocation represents risk-adjusted cash flows
  related to the incomplete products. At the date of acquisition, the
  development of these projects had not yet reached technological feasibility
  and the research and development in progress had no alternative future
  uses. Accordingly, these costs were expensed as of the acquisition date.

  Cabletron used independent third-party appraisers to assess and allocate
  values to the in-process research and development. The value assigned to
  these assets were determined by identifying significant research projects
  for which technological feasibility had not been established, including
  development, engineering and testing activities associated with the
  introduction of the Company's next-generation router technologies.

  The nature of the efforts to develop the acquired in-process technology
  into commercially viable products principally relate to the completion of
  all planning, designing, prototyping, high-volume verification, and testing
  activities that are necessary to establish that the proposed technologies
  meet their design specifications including functional, technical, and
  economic performance requirements.

  To date, the Company's results have not differed significantly from the
  forecast assumptions. The Company's research and development expenditures
  since the acquisition have not differed materially from expectations. The
  Company has completed the projects that were underway at the time of the
  acquisition and began to realize the economic benefits related to these
  projects during the six months ended February 28, 1999.

  The value assigned to purchased in-process technology was determined by
  estimating the costs to develop the purchased in-process technology into
  commercially viable products, estimating the resulting net cash flows from
  the projects and discounting the net cash flows to their present value. The
  revenue projection used to value the in-process research and development is
  based on estimates of relevant market sizes and growth factors, expected
  trends in technology and the nature and expected timing of new product
  introductions by the Company and its competitors.

  For purposes of the IPR&D valuation, the total revenues attributable to the
  Company were projected to exceed $150 million within 5 years, assuming the
  successful completion and market acceptance of the major research and
  development efforts. As of the valuation date, the Company had a few
  existing products, which lack the technological breadth and depth necessary
  in the evolving networking equipment market. Accordingly, for purposes of
  the IPR&D valuation, it was estimated that significant revenue growth in
  the first several years would be primarily related to the in-process
  technologies. The estimated revenues for the in-process projects were
  projected to peak in 2004 and then decline as other new products and
  technologies were expected to enter the market.

  Cost of sales was estimated based on the Company's internally generated
  projections and discussions with management regarding anticipated gross
  margin improvements. Due to the market opportunities in the network
  equipment arena and the Company's unique technology architecture,
  substantial gross margins were projected through the forecast period. Cost
  of sales as a percentage of sales was forecasted to decline until 2003 and
  then remain constant at 55%. Selling, general and administrative expenses
  (including depreciation) as a percentage of sales were projected to remain
  constant at 23%. Research and

    (Information as of and for the seven months ended September 30, 1999 is
                                   unaudited)

  development expenditures as a percentage of sales were projected to decline
  significantly from 30% in 1999 to 10% in 2001 and remain constant at 10%
  thereafter.

  The rates utilized to discount the net cash flows to their present value
  were based on venture capital rates of return. Due to the nature of the
  forecast and the risks associated with the projected growth, profitability
  and developmental projects, a discount rate of 27.5 percent was determined
  to be appropriate for the IPR&D. This discount rate was commensurate with
  the Company's stage of development; the uncertainties in the economic
  estimates described above; the inherent uncertainty surrounding the
  successful development of the purchased in-process technology; the useful
  life of such technology; the profitability levels of such technology; and,
  the uncertainty of technological advances that were unknown at the time of
  the acquisition.

  The forecasts used by Cabletron in valuing in-process research and
  development were based upon assumptions Cabletron believes to be reasonable
  but which are inherently uncertain and unpredictable. Cabletron's
  assumptions may be incomplete or inaccurate, and unanticipated events and
  circumstances are likely to occur. For these reasons, actual results may
  vary from the projected results.

  Cabletron believes that the foregoing assumptions used in the forecasts
  were reasonable at the time of the acquisition. No assurance can be given,
  however, that the underlying assumptions used to estimate expected project
  sales, development costs or profitability, or the events associated with
  such projects, will transpire as estimated. For these reasons, actual
  results may vary from the projected results.

  The Company's in-process research and development value is comprised of
  several significant individual on-going projects. Remaining development
  efforts for these projects include various phases of design, development
  and testing. Anticipated completion dates for the projects in progress are
  estimated to occur over the first nine months following the acquisition.
  The Company estimated it will begin generating the economic benefits from
  the technologies in the second half of fiscal year 2000. Funding for such
  projects was estimated to be obtained from internally generated sources.
  Expenditures to complete these projects were estimated to total
  approximately $1.0 million over the next six months. These estimates are
  subject to change, given the uncertainties of the development process, and
  no assurance can be given that deviations from these estimates will not
  occur.

  Cabletron management expects to continue their support of these efforts and
  believes the Company has a reasonable chance of successfully completing the
  research and development programs. However, there is risk associated with
  the completion of the projects and there is no assurance that any will meet
  with either technological or commercial success.

  Prior to the acquisition by Cabletron, the Company leased a manufacturing
  and office facility under an operating lease. In June 1999, the Company
  relocated to a facility leased by Cabletron. Cabletron allocates a portion
  of its lease cost to the Company. Rent expense, including intercompany
  allocations for the seven months ended September 30, 1999, the six months
  ended February 28, 1999, the five months ended August 31, 1998 and the

  At September 30, 1999, February 28, 1999, August 31, 1998 and March 31,
  1998, the Company had net operating loss (NOL) carryforwards for tax
  purposes of $5,695,112, $6,187,662, $5,695,112, and $4,129,836 respectively
  expiring in fiscal February 2008 through fiscal February 2011. The
  utilization of these net operating losses may be limited pursuant to
  Internal Revenue Code section 382 as a result of ownership changes.

                   Notes to Financial Statements--(Continued)

    (Information as of and for the seven months ended September 30, 1999 is
                                   unaudited)


  The valuation allowance was increased by $0, $0, $579,739 and $721,065
  during the periods ended September 30, 1999, February 28, 1999, August 31,
  1998 and March 31, 1998, respectively. Subsequently reported tax benefits
  relating to the valuation allowance for deferred tax assets as of September
  30, 1999, February 28, 1999 and August 31, 1998 will be recorded as a
  decrease to goodwill and other non-current intangible assets. In assessing
  the realizability of net deferred tax assets, management considers whether
  it is more likely than not that some portion or all of the deferred tax
  assets will not be realized. Based upon the level of historical taxable
  income and projections for future taxable income over the periods which the
  deferred tax assets are deductible, management believes it is more likely
  than not the Company will realize the benefits of these deductible
  differences, net of the existing valuation allowance at September 30, 1999.

(9)Related Party Notes Payable
  On August 8, 1995, the Company entered into a $250,000 note payable with
  Soliton Systems, K.K. ("Soliton") with an interest rate of five percent. On
  August 5, 1997, the note was amended to require variable quarterly
  repayments of the note over three years with the principle amount
  outstanding at the end of three years due in full. The Company repaid the
  note in full on October 8, 1998. Soliton was a preferred stock shareholder
  of the Company.

  In anticipation of Cabletron's acquisition of the Company, the two parties
  entered into a Memorandum of Understanding ("MOU") on February 4, 1998. As
  part of the MOU, the Company entered into a note payable to Cabletron for
  $2,225,000 with an interest rate of six percent. The note payable was
  convertible into shares of Series E Preferred Stock of the Company at $7.50
  per share if the acquisition was not consummated.

(10) Financial Instruments and Concentration of Credit Risk

  The carrying amounts of cash and cash equivalents, accounts receivables,
  and current liabilities approximate fair value because of the short
  maturity of these financial instruments.

  The carrying amount of the notes payable to Cabletron, as discussed in note
  9, approximated fair value based on the short maturity of the instrument.
  The carrying amount of the note payable to Soliton also approximated fair
  value based on estimated discounted cash flows prior to the repayment by
  the Company.

  For the seven months ended September 30, 1999 and the six months ended
  February 28, 1999, the Company had one customer, Covad and a related party,
  Cabletron, which accounted for 52% and 26% of sales and 70% and 17% of
  sales, respectively. For the five months ended August 31, 1998, the Company
  had two customers, Covad and British Telecom that accounted for 28% and 19%
  of sales, respectively. Additionally for this same period sales to related
  parties, Cabletron and Soliton, accounted for 25% and 21% of sales,
  respectively. For the year ended March 31, 1998, the Company had one
  customer, Diamond Lane, which accounted for 36% of sales. Additionally for
  this same period sales to related parties, Cabletron and Soliton, accounted
  for 31% and 11% of sales, respectively. For the year ended March 31, 1997,
  sales to related parties, Cabletron and Soliton, accounted for 69% and 20%
  of sales, respectively.

(11) Segment and Geographical Information

  The Company operates in one operating segment. The Company provides a line
  of broadband remote access, high-speed corporate and internet access modems
  and routers primarily utilizing DSL technologies. Substantially all
  revenues result from the sales of hardware products. The vast majority of
  the Company's sales are generated in the United States.

(12) Related Party

  Subsequent to the acquisition date, the Company maintained a certain level
  of autonomy. During the six months ended February 28, 1999, Cabletron
  provided the Company with certain services including cash management,
  payroll processing, insurance, limited legal and information technology
  support as well as the ability for Company employees to participate in
  Cabletron's medical plan beginning in January of 1999. During this period,
  Cabletron began to allocate expenses primarily related to the medical plan
  coverage to the Company on a monthly basis as the costs associated with the
  other services were nominal. The total amount of expenses allocated to the
  Company by Cabletron during the six months ended February 28, 1999 was
  $15,026 and is included in the respective categories in the statement of
  operations including cost of sales, selling general and administrative, and
  research and engineering expenses.
  Also beginning in the six month period ending February 28, 1999, Company
  employees were able to participate in Cabletron's incentive plans. These
  plans include Cabletron's Equity Incentive Plan and the Employee Stock
  Purchase Plan. These plans are accounted for by Cabletron as non-
  compensatory under APB 25 and thus there is no expense allocation.

  Beginning in the seven month period ending September 30, 1999, Cabletron
  began to provide the Company with services in addition to those described
  above. These services included external and inside sales support, customer
  service and technical support, software licenses, limited software
  development and assistance with year 2000 remediation processes. The
  Company also moved into a Cabletron facility in June of 1999 and began to
  receive a related cost allocation from Cabletron representing rent and
  other occupancy costs. The total amount of expenses allocated to the
  Company by Cabletron during the seven months ended September 30, 1999 was
  $574,151 and is included in the respective categories in the statement of
  operations including cost of sales, selling general and administrative, and
  research and engineering expenses.

  Cabletron was a significant customer of the Company prior to the completion
  of the acquisition and the Company has generated significant intercompany
  sales to Cabletron subsequent to the acquisition as outlined in footnote 10
  of these financial statements.

(13) Stockholders' Equity

  The Company's preferred stock was convertible into common stock on a one-
  for-one conversion rate. Each holder of preferred stock was entitled to
  vote on all matters and was entitled to the number of votes equal to the
  whole number of shares of common stock into which such preferred shares
  could be converted. Dividends on the preferred stock were not cumulative
  and no right to any dividends would accrue to the holders unless declared
  by the Board of Directors.

  The preferred stock had liquidation preferences as follows:

</TABLE>

  Prior to the acquisition by Cabletron, the Company maintained a 1994 Stock
  Option Plan (the "Plan") which provided for up to 400,000 shares of common
  stock of the Company for purchase by employees, directors or consultants of
  the Company. The Plan was amended on October 1, 1997 to provide up to

  600,000 shares. The Plan provides for issuance of options at their fair
  market value on the date of the grant. The Plan allowed varying vesting
  provisions but in each case the options were issued with four year vesting
  periods. The Plan also includes a provision whereby at least 20% per year
  of the total number of shares pursuant to a grant would vest. The maximum
  term for an option was ten years from the date of grant. As part of the
  acquisition by Cabletron, the options for Company common stock were
  converted to options for Cabletron common stock.

  Subsequent to the acquisition by Cabletron, Company employees were eligible
  to participate in Cabletron's Equity Incentive Plan ("EIP") which provides
  shares of common stock for the granting of a variety of incentive awards to
  eligible employees. As of February 28, 1999, Cabletron had issued Company
  employees 75,100 stock options under the EIP, which were granted at fair
  market value at the date of grant, vest over a three to five year period

  The Company accounts for its stock option plans in accordance with the
  provisions of APB 25. As such compensation expense is recorded on the date
  of grant only if the fair value of the underlying stock exceeds the
  exercise price. Had compensation cost associated with options held by
  Company employees been determined consistent with SFAS 123, the Company
  would have reported net losses of $13,078,156, $1,660,426, $2,077,613, and
  $1,503,479, respectively for the six months ended February 28, 1999, the
  five months ended August 31, 1998 and the years ended March 31, 1998 and
  1997.

  *based on Company employee holdings in Cabletron common stock

  The weighted average estimated fair values of stock options granted during
  the six months ended February 28, 1999, the five months ended August 31,
  1998 and the fiscal years ended March 31, 1998 and 1997 were $7.63, $.73,
  $.25 and $.17 per share, respectively.

  Also subsequent to the acquisition by Cabletron, Company employees were
  eligible to participate in Cabletron' two Employee Stock Purchase Plans
  ("ESPPs"), which provide shares of common stock to be purchased by
  employees who have completed a minimum period of employment. Under the 1989
  ESPP, employees must be continuously employed for a period of six months
  and under the 1995 ESPP employees must be continuously employed for a
  period of two years. Under these plans, options are granted to eligible
  employees twice yearly and are exercisable through the accumulation of
  employee payroll deductions from two to ten percent of employee
  compensation as defined in the plan, to a maximum of $12,500 annually, for
  each plan, (adjusted to reflect increases in the consumer price index)
  which may be used to purchase stock at 85 percent of the fair market value
  of the common stock at the beginning or end of the option period, whichever
  amount is lower. In the seven months ended September 30, 1999, 6,932 shares
  were purchased at a weighted average price of $6.96.

(14)Subsequent Event (Unaudited)
  On November 22, 1999, Cabletron announced that it had reached an agreement
  for the sale of the Company to Efficient Networks ("Efficient") a leading,
  independent supplier of DSL access products for the customer premises.
  Under the terms of the sale, Efficient would pay a combination of 7.2
  million common shares and 6,300 convertible preferred shares (convertible
  into an aggregate of 6.3 million common shares of Efficient) to Cabletron
  in exchange for all the outstanding common stock of the Company. The sale
  closed on December 17, 1999.
