<P align="left" style="font-size: 10pt"><B>1. Description of Business</B>

<P align="left" style="font-size: 10pt"><B>2. Summary of Significant Accounting Policies</B>


<P align="left" style="font-size: 10pt"><B>Basis of Presentation</B>



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In the opinion of management, the unaudited consolidated financial
statements reflect all adjustments, consisting only of normal recurring
adjustments, necessary for their fair presentation in conformity with
accounting principles generally accepted in the United States of America.
Certain information and footnote disclosures normally included in annual
financial statements have been condensed or omitted in accordance with the
rules and regulations of the Securities and Exchange Commission. The
information included in this Form 10-Q should be read in conjunction with
Management&#146;s Discussion and Analysis of Financial Condition and Results of
Operations and financial statements and notes thereto included in the Company&#146;s
Annual Report on Form 10-K for the fiscal year ended September&nbsp;30, 2003.


<P align="left" style="font-size: 10pt"><B>Revenue Recognition</B>


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company recognizes revenue in accordance with the guidance provided
under Statement of Position (SOP)&nbsp;No.&nbsp;97-2, &#147;Software Revenue Recognition,&#148; and
SOP No.&nbsp;98-9 &#147;Modification of SOP No.&nbsp;97-2, Software Revenue Recognition, with
Respect to Certain Transactions,&#148; Statement of Financial Accounting Standards
(SFAS)&nbsp;No.&nbsp;48, &#147;Revenue Recognition When Right of Return Exists,&#148; and SEC Staff
Accounting Bulletin (SAB)&nbsp;No.&nbsp;101, &#147;Revenue Recognition in Financial
Statements,&#148; and SAB No.&nbsp;104, &#147;Revenue Recognition.&#148;


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company sells products through distributors, resellers, and directly
to end users. The Company recognizes product revenue upon shipment, net of
estimated returns, provided that collection is determined to be probable and no
significant obligations remain. In certain regions where the Company does not
have the ability to reasonably estimate returns, revenue is recognized upon
sale to the end user. In this situation, the Company receives a sales report
from the channel partner to determine when the sales transaction to the end
user has occurred. Payment terms to domestic customers are generally net 30
days. Payment terms to international customers range from net 30 to 90&nbsp;days
based on normal and customary trade practices in the individual markets. The
Company has offered extended payment terms ranging from three to six months to
certain customers, in which case, revenue is recognized when payments become
due.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Whenever a software license, hardware, installation and post-contract
customer support (PCS)&nbsp;elements are combined into a package with a single
&#147;bundled&#148; price, a portion of the sales price is allocated to each element of
the bundled package based on their respective fair values as determined when
the individual elements are sold separately. Revenues from the license of
software are recognized when the software has been shipped and the customer is
obligated to pay for the software. When rights of return are present and we
cannot estimate returns, we recognize revenue when such rights of return lapse.
Revenues for PCS are recognized on a straight-line basis over the service
contract term. PCS includes rights to upgrades, when and if available, a
limited period of telephone support, updates, and bug fixes. Installation
revenue is recognized when the product has been installed at the customer&#146;s
site. Consulting services are customarily billed at fixed rates, plus
out-of-pocket expenses, and revenues

recognized when the training has been completed.



<P align="left" style="font-size: 10pt"><B>Goodwill and Acquired Technology</B>


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Goodwill represents the excess purchase price over the estimated fair
value of net assets acquired as of the acquisition date. The Company has
adopted the requirements of Statement of Financial Accounting Standards No.
142, &#147;Goodwill and Other Intangible Assets&#148; (SFAS No.&nbsp;142). SFAS No.&nbsp;142
requires goodwill to be tested for impairment on an annual basis and between
annual tests in certain circumstances, and written down when impaired. Goodwill
of $24.2&nbsp;million was recorded in connection with the acquisition of uRoam, Inc.
in July&nbsp;2003. There was no impairment of goodwill during the six months ended
March&nbsp;31, 2004.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Acquired technology of $3.0&nbsp;million was recorded in connection with the
acquisition of uRoam, Inc. Acquired technology is recorded at cost and
amortized over its estimated useful life of five years. Related amortization
expense totaled $300,000 for the six months ended March&nbsp;31, 2004.


<P align="left" style="font-size: 10pt"><B>Stock-Based Compensation</B>


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company accounts for stock-based employee compensation arrangements in
accordance with the provisions of Accounting Principles Board Opinion No.&nbsp;25
(&#147;APB No.&nbsp;25&#148;), &#147;Accounting for Stock Issued to Employees,&#148; FASB Interpretation
No.&nbsp;44 (&#147;FIN No.&nbsp;44&#148;) &#147;Accounting for Certain Transactions Involving Stock
Compensation,&#148; and related interpretations and complies with the disclosure
provisions of Statement of Financial Accounting Standards No.&nbsp;123 (&#147;SFAS No.
123&#148;), &#147;Accounting for Stock-Based Compensation.&#148; Under APB No.&nbsp;25,
compensation expense is based on the difference, if any, on the date of the
grant, between the fair value of our stock and the exercise price of the
option. The unearned compensation is amortized in accordance with Financial
Accounting Standards Board Interpretation No.&nbsp;28 on an accelerated basis over
the vesting period of the individual options.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Pro forma information regarding net income is required by SFAS No.&nbsp;123,
and has been determined as if the Company had accounted for stock options under
the fair value method. For purposes of pro forma disclosures, the estimated
fair value of the options is amortized over the options&#146; vesting period. The
net income and net income per share would have been adjusted to the pro forma

<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Approximately 1.0&nbsp;million and 3.9&nbsp;million common shares potentially
issuable from stock options for the three months ended March&nbsp;31, 2004 and 2003,
respectively, are excluded from the calculation of diluted earnings per share
because the effect was antidilutive. Approximately 1.4&nbsp;million and 4.0&nbsp;million
of common shares potentially issuable from stock options for the six months
ended March&nbsp;31, 2004 and 2003, respectively, are excluded from the calculation
of diluted earnings per share because the effect was antidilutive.


<P align="left" style="font-size: 10pt"><B>Recent Accounting Pronouncements</B>


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In January&nbsp;2003, the FASB issued Interpretation No.&nbsp;46 (FIN 46),
&#147;Consolidation of Variable Interest Entities,&#148; which addresses consolidation by
business enterprises of variable interest entities that either: (1)&nbsp;do not have
sufficient equity investment at risk to permit the entity to finance its
activities without additional subordinated financial support, or (2)&nbsp;the
company will hold a significant variable interest in, or have significant
involvement with, an existing variable interest entity.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In October&nbsp;2003, the FASB deferred the effective date of FIN 46 for
variable interests held by public companies in all entities that were acquired
prior to February&nbsp;1, 2003. The deferral requires that public companies adopt
the provisions of FIN 46 at the end of fiscal periods ending after December&nbsp;15,
2003. The adoption of this interpretation will not have an impact on the
Company&#146;s consolidated financial statements.


<P align="left" style="font-size: 10pt"><B>3. Commitments and Contingencies</B>


<P align="left" style="font-size: 10pt"><B>Guarantees and Product Warranties</B>



<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In the normal course of business to facilitate sales of its products, the
Company indemnifies other parties, including customers, resellers, lessors, and
parties to other transactions with the Company, with respect to certain
matters. The Company has agreed to hold the other party harmless against losses
arising from a breach of representations or covenants, or out of intellectual
property infringement or other claims made against certain parties. These
agreements may limit the time within which an indemnification claim can be made
and the amount of the claim. In addition, the Company has entered into
indemnification agreements with its officers and directors, and the Company&#146;s
bylaws contain similar indemnification obligations to the Company&#146;s agents. It
is not possible to determine the maximum potential amount of liability under
these indemnification agreements due to the limited history of prior
indemnification claims and the unique facts and circumstances involved in each
particular agreement.

<P align="left" style="font-size: 10pt"><B>Purchase Commitments</B>


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company currently has arrangements with contract manufacturers and
other suppliers for the manufacture of the Company&#146;s products. The arrangement
with the primary contract manufacturer allows them to procure component
inventory on the Company&#146;s behalf based on a rolling production forecast
provided by the Company. The Company is obligated to the purchase of component
inventory that the contract manufacturer procures in accordance with the
forecast, unless cancellation is given outside of applicable lead times. As of
March&nbsp;31, 2004, the Company was committed to purchase approximately $6.1
million of such inventory over the next two quarters.


<P align="left" style="font-size: 10pt"><B>Litigation</B>


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company is not aware of any pending legal proceedings that,
individually or in the aggregate, would have a material adverse effect on the
Company&#146;s business, operating results, or financial condition. The Company may
in the future be party to litigation arising in the ordinary course of
business, including claims that allegedly infringe upon third-party trademarks
or other intellectual property rights. Such claims, even if not meritorious,
could result in the expenditure of significant financial and managerial
resources.


<P align="left" style="font-size: 10pt"><B>4. Restructuring Charge</B>


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;During the fiscal year 2002, the Company executed on a restructuring plan
that included the discontinuation of its cache appliance business. As a result
of discontinuing this line of business and other changes in the overall
business, the Company incurred restructuring charges of $3.3&nbsp;million in the
fiscal year 2002. The restructuring charges included employee termination
benefits, impaired assets, consolidation of excess facilities, and other
obligations for which the Company no longer derives an economic benefit. There
were no restructuring charges for the three months ended March&nbsp;31, 2004 and
2003.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The activity to March&nbsp;31, 2004 of the remaining restructuring liability
included as a component of accrued liabilities on the balance sheet as of
September&nbsp;30, 2003 is presented below (in thousands):

exit its support facility in Washington DC and was estimated based on current
comparable rates for leases in the respective market. In April&nbsp;2003, the
excess facilities were subleased at the then current market value. The
difference between the lease payments and sublease income has historically been
applied against the restructuring liability. The excess facilities liability
is scheduled to be paid over the remaining term of the lease ending in April
2007. During the three months ended

and the collectibility of sublease income was in question. Because of this
uncertainty, neither the rent payment nor receipt of sublease income was
applied against the restructuring liability during the December quarter.
However, during the three months ended March&nbsp;31, 2004 we received payments of
sublease income and have therefore applied the rent payment and the sublease
income against the restructuring liability. In the event we are unable to
collect sublease income throughout the duration of the lease term, the actual
loss may be increased from the original estimate.

<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We are a global provider of software and hardware products and services
that help companies efficiently and securely manage their Internet traffic. We
enable our customers to keep their IP-based Internet traffic flowing and
business information always available to any user from any device, anywhere in
the world. Our products ensure secure and reliable access to servers and the
applications that run on them. We market and sell our products primarily
through indirect sales channels in North America, Europe, Japan and the Asia
Pacific region, and to some direct customer accounts in North America.
Enterprise customers (Fortune 1000 or Business Week Global 1000 companies) in
financial services, manufacturing, transportation and mobile telecommunications
continues to make up the largest percentage of our customer base.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our management monitors and analyzes a number of key performance
indicators in order to manage our business and evaluate our financial and
operating performance. Those indicators include:

products; BIG-IP server appliances; BIG-IP application switches;
3-DNS Controller; BIG-IP Link Controller; and FirePass SSL VPN
servers. We also derive revenues from the sales of services
including annual maintenance contracts, installation, training and
consulting services. We carefully monitor the sales mix of our
revenue within the reporting period. We believe customer acceptance
rates of our new products and feature enhancements are key
indicators of future trends. Additionally, we believe the growth in
our service revenues is a key indicator of our successes in
penetrating large enterprise accounts. We also consider overall
revenue concentration by customer and by geographic region as
additional indicators of current and future trends.</TD>

<P align="left" style="font-size: 10pt"><B>Critical Accounting Policies and Estimates</B>


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our consolidated financial statements have been prepared in accordance
with accounting principles generally accepted in the United States of America.
The preparation of these financial statements requires us to make estimates and
judgments that affect the reported amounts of assets, liabilities, revenues and
expenses, and related disclosure of contingent assets and liabilities. We base
our estimates on historical experience and on various other assumptions that
are believed to be reasonable under the circumstances. Actual results may
differ from these estimates under different assumptions or conditions.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We believe the following critical accounting policies affect the more
significant judgments and estimates used in the preparation of our financial
statements. These critical accounting policies are consistent with those
disclosed in our Annual Report on Form 10-K.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>Revenue Recognition. </I>We recognize revenue in accordance with the guidance
provided under Statement of Position (SOP)&nbsp;No.&nbsp;97-2, &#147;Software Revenue
Recognition,&#148; and SOP No.&nbsp;98-9 &#147;Modification of SOP No.&nbsp;97-2, Software Revenue
Recognition, with Respect to Certain Transactions.&#148; Statement of Financial
Accounting Standards (SFAS)&nbsp;No.&nbsp;48, &#147;Revenue Recognition When Right of Return
Exists,&#148; and Securities and Exchange Commission, or SEC, Staff Accounting
Bulletin (SAB)&nbsp;No.&nbsp;101, &#147;Revenue Recognition in Financial Statements,&#148; and SAB
No.&nbsp;104, &#147;Revenue Recognition.&#148;


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company sells products through distributors, resellers, and directly
to end users. The Company recognizes product revenue upon shipment, net of
estimated returns, provided that collection is determined to be probable and no
significant obligations remain. In certain regions where the Company does not
have the ability to reasonably estimate returns, revenue is recognized upon
sale to the end user. Payment terms to domestic customers are generally net 30
days. Payment terms to international customers range from net 30 to 90&nbsp;days
based on normal and customary trade practices in the individual markets. The
Company has offered extended payment terms to certain customers, in which case,
revenue is recognized when payments become due.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Whenever a software license, hardware, installation and post-contract
customer support (PCS)&nbsp;elements are combined into a package with a single
&#147;bundled&#148; price, a portion of the sales price is allocated to each element of
the bundled package based on their respective fair values as determined when
the individual elements are sold separately. Revenues from the license of
software are recognized when the software has been shipped and the customer is
obligated to pay for the software. When rights of return are present and we
cannot estimate returns, we recognize revenue when such rights of return lapse.
Revenues for PCS are recognized on a straight-line basis over the service
contract term. PCS includes rights to upgrades, when and if available, a
limited period of telephone support, updates, and bug fixes. Installation
revenue is recognized when the product has been installed at the customer&#146;s
site. Consulting services are customarily billed at fixed rates, plus
out-of-pocket expenses, and revenues are recognized when the consulting has
been completed. Training revenue is recognized when the training has been
completed.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>Reserve for Doubtful Accounts. </I>Estimates are used in determining our
allowance for doubtful accounts and are based on a percentage of our accounts
receivable by aging category. In determining these percentages, we evaluate
historical write-offs, current trends in the credit quality of our customer
base, as well as changes in the credit policies. We perform ongoing credit
evaluations of our customers&#146; financial condition and generally do not require
any collateral. If there is a deterioration of a major customer&#146;s credit
worthiness or actual defaults are higher than our historical experience, our
allowance for doubtful accounts may not be sufficient.

<H5 align="left" style="page-break-before:always"><A HREF="#tocpage">Table of Contents</A></H5><P>

<DIV style="font-family: 'Times New Roman',Times,serif">

<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>Reserve for Product Returns. </I>Product returns are estimated based on
historical experience and are recorded at the time revenues are recognized. In
some instances, product revenue from distributors is subject to agreements
allowing rights of return. Accordingly, we reduce recognized revenue for
estimated future returns at the time revenue is recorded. When rights of return
are present and we cannot estimate returns, revenue is recognized when such
rights lapse. The estimates for returns are adjusted periodically based upon
changes in historical rates of returns, inventory in the distribution channel,
and other related factors. It is possible that these estimates will change in
the future or that the actual amounts could vary from our estimates and result
in reductions to recognized revenues.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>Reserve for Excess or Obsolete Inventory. </I>We currently reserve for
estimated obsolescence or unmarketable inventory equal to the difference
between the cost of inventory and the estimated net realizable value based upon
assumptions about future demand and market conditions. If actual market
conditions are less favorable than those projected by management, additional
inventory charges may be required.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>Reserve for Warranties. </I>A warranty reserve is established based on our
historical experience and an estimate of the amounts necessary to settle future
and existing claims on products sold as of the balance sheet date. While we
believe that our warranty reserve is adequate and that the judgment applied is
appropriate, such amounts estimated to be due and payable could differ
materially from what will actually transpire in the future.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>Income Tax Valuation Allowance. </I>The Company has net deferred tax assets
which are fully offset by a valuation allowance due to management&#146;s
determination that the criteria for recognition have not been met. In the event
management were to determine that the Company would be able to realize its net
deferred tax assets in the future, an adjustment to the deferred tax assets
would be made, increasing net income (or decreasing net loss) in the period in
which such a determination was made. Based on current and expected financial
trends, the Company&#146;s management believes that the valuation allowance will be
released sometime within the next few quarters. Factors such as cumulative
profitability of the U.S. operations and projected future taxable income are
examples of the key criteria the Company uses for determining if and when the
valuation allowance will be released.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>Goodwill. </I>The Company accounts for goodwill in accordance with SFAS No.
141, &#147;Business Combinations.&#148; Under the purchase method of accounting, the
total purchase price is allocated to the tangible and intangible assets
acquired and the liabilities assumed based on their estimated fair values.
Goodwill is the excess of the purchase price (including liabilities assumed and
direct costs) over the fair value of tangible and identifiable intangible
assets acquired in purchase business combinations. Goodwill is not amortized
but reviewed for impairment annually.

<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>Net revenues. </I>Total net revenues increased 45.1% and 39.3% for the three
and six months ended March&nbsp;31, 2004, respectively, up from comparable periods
in the prior year. The increases were due to higher services revenues and
increased demand for our application traffic management products, primarily in
our international markets. International revenues grew to 45.0% of total net
revenues for the three months ended March&nbsp;31, 2004 compared to 37.4% for the
same period in the prior year. International revenues grew to 39.9% of total
net revenues for the six months ended March&nbsp;31, 2004 compared to 33.9% for the
same period in the prior year. The increase in international revenue was
primarily attributed to higher sales in Japan driven by Japanese financial year
end spending. We expect international revenues to return to historical levels
over the remainder of fiscal 2004.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Net product revenues increased 46.1% and 40.8% for the three and six
months ended March&nbsp;31, 2004, respectively, up from the comparable periods in
the prior year. The increase was primarily due to growth in the volume of
product sales and customer acceptance of our switch based BIG-IP product as
well as continued growth in revenues from our recently acquired FirePass
product line. Sales of our BIG-IP products represented 77.2% and 82.9% of
product revenues for the three months ended March&nbsp;31, 2004 and 2003,
respectively and 77.4% and 82.6% of product revenues for the six months ended
March&nbsp;31, 2004 and 2003, respectively. The decrease as a percentage of total
sales was due to an improvement in sales of our other products, such as our
newly introduced FirePass SSL VPN product which represented 9.0% and 7.4% of
product revenues for the three and six months ended March&nbsp;31, 2004,
respectively.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Net services revenues increased 42.3% and 35.4% for the three and six
months ended March&nbsp;31, 2004, respectively, up from the comparable periods in
the prior year. The increase in services revenue was primarily due to
increases in the purchase or renewal of service and support contracts as our
installed base of products increased.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Ingram Micro Inc., one of our domestic distributors, accounted for 15.6%
and 11.7% of our total net revenues for the three months ended March&nbsp;31, 2004
and 2003, respectively. For the six months ended March&nbsp;31, 2004, this
distributor accounted for 16.2% of our total net revenues. Ingram Micro Inc.
accounted for 22.7% of our accounts receivable as of March&nbsp;31, 2004.

<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>Cost of Net Product Revenues</I>. The increase in cost of product revenues as
a percentage of net product revenue was primarily due to variations in the
product sales mix and higher amortization charges in connection with the
developed technology we purchased from uRoam, Inc. Related amortization
expenses totaled $0.3&nbsp;million for the six months ended March&nbsp;31, 2004. Our new
FirePass SSL VPN product line has product costs comparable to our BIG-IP
product line and is not by itself expected to impact the overall gross margin
trends in the near future.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>Cost of Net Services Revenues</I>. The increase in absolute dollars was due
primarily to increased salary and benefits expenses as a result of an increase
in professional services employee headcount. The decrease in cost of net
services revenues as a percentage of net services revenues is primarily the
result of leveraging our existing services operating infrastructure to support
the increased net services revenue.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We expect to maintain our gross margins in the near term; however, gross
margins could be adversely affected by increased material costs, component
shortages, excess and obsolete inventory charges and heightened sales price
competition.

<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>Sales and marketing. </I>Sales and marketing expenses consist primarily of
salaries, commissions and related expenses of our sales and marketing staff,
costs of our marketing programs, including public relations, advertising and
trade shows, facilities and depreciation expenses. Sales and marketing
expenses increased 21.9% and 19.6% for the three and six months ended March&nbsp;31,
2004, respectively, up from the comparable periods in the prior year. The
increase in sales and marketing expenses was primarily due to higher salary,
commission and employee benefit related expenses. In the future, we expect to
continue to increase our sales and marketing expenses to grow revenues and
increase our market share.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>Research and development</I>. Research and development expenses consist
primarily of salaries and benefits for our product development personnel,
prototype materials and expenses related to the development of new and improved
products, facilities and depreciation expenses. Research and development
expenses increased by 20.8% and 22.2% for the three and six months ended March
31, 2004, respectively, up from the comparable periods in the prior year. The
increase in research and development expenses was primarily due to increased
prototype expenses and an increase in payroll and related costs due to an
increase in headcount related to our acquisition of the FirePass product line
from uRoam, Inc. R&#038;D employee headcount at the end of March&nbsp;2004 totaled 164
up from 125 at the end of March&nbsp;2003. We expect to continue to increase
research and development expenses as our future success is dependent on the
continued enhancement of our current products and our ability to develop new,
technologically advanced products that meet the changing needs of our
customers.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>General and administrative</I>. General and administrative expenses consist
primarily of salaries and related expenses of our executive, finance,
information technology, human resource and legal personnel, third-party
professional service fees, bad debt charges, facilities and depreciation
expenses. General and administrative expenses increased 32.9% and 15.2% for
the three and six months ended March&nbsp;31, 2004, respectively, up from the
comparable periods in the prior year. The increase in general and
administrative expenses was primarily due to increased salary and benefit
expenses and higher legal expenses related to a patent suit filed by us against
a competitor. G&#038;A employee headcount at the end of March&nbsp;2004 totaled 74 up
from 64 total G&#038;A headcount at the end of March&nbsp;2003.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>Amortization of unearned compensation. </I>We have recorded $8.3&nbsp;million of
stock compensation costs since our inception through March&nbsp;31, 2004. These
compensation costs represented the difference between the exercise price and
the deemed fair value of certain stock options granted to our employees and
outside directors. These stock options generally vested ratably over a
four-year period. We amortized these compensation costs using an accelerated
method as prescribed by FASB interpretation No.&nbsp;28 (&#147;FIN No.&nbsp;28&#148;). As of
December&nbsp;31, 2003, the balance of unearned compensation was fully amortized and
no amortization of unearned compensation was recorded during the three months
ended March&nbsp;31, 2004.

<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>Other income, net. </I>Other income, net, consists primarily of interest
income and foreign currency transaction gains and losses. Other income, net,
increased 159.0% for the three months ended March&nbsp;31, 2004 from the same period
in the prior year. The increase was primarily due to interest income earned on
the proceeds from our public offering completed in November of 2003. For the
six months ended March&nbsp;31, 2004 other income, net, increased 28.2% from the
same period in the prior year. The increase was primarily due to higher
interest income partially offset by higher foreign currency losses realized in
the first quarter of fiscal year 2004.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>Income taxes</I>. The provision for income tax for the three and six months
ended March&nbsp;31, 2004 and 2003, primarily consists of foreign taxes related to
our international operations. The provision for income taxes in the three and
six months ended March&nbsp;31, 2004 also includes charges for deferred tax
liabilities associated with the amortization of goodwill. We have a full
valuation allowance to offset U.S. deferred tax assets in accordance with the
provisions of FAS 109. We continue to monitor and evaluate the realizability
of our U.S. deferred tax assets. If it is determined that it is more likely
than not that the U.S. deferred tax assets are recoverable by the availability
of future taxable income, the valuation allowance will be reversed in a future
reporting period. For the three and six months ended March&nbsp;31, 2004 we
continued to incur U.S. tax losses primarily due to the tax benefits received
from employee stock option deductions. At March&nbsp;31, 2004, a significant
portion of the valuation allowance of our net operating loss carryforwards is
derived from the tax benefits of stock option deductions. At such time as the
valuation allowance related to these deductions is released, a significant
proportion of the benefit is expected to be credited to additional paid in
capital. Based on current and expected financial trends, we believe that the
valuation allowance will be released sometime within the next few quarters.
Factors such as cumulative profitability of the U.S. operations and projected
future taxable income are examples of the key criteria the Company uses for
determining if and when the valuation allowance will be released.


<P align="left" style="font-size: 10pt"><B>Financial Condition</B>


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Cash and cash equivalents, short-term investments and long-term
investments totaled $227.3&nbsp;million as of March&nbsp;31, 2004 compared to $79.0
million as of September&nbsp;30, 2003, representing an increase of $148.3&nbsp;million.
The significant increase was primarily due to the net proceeds of $113.6
million, generated by the sale of 5,175,000 shares of common stock in a public
offering in November&nbsp;2003. In addition, cash flow from operations and cash
generated from employee stock option exercises contributed to the overall
increase.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Cash provided by operating activities was $18.6&nbsp;million for the six months
ended March&nbsp;31, 2004 compared to $5.6&nbsp;million for the same period in the prior
year. During the first half of fiscal 2004, operating cash was primarily
provided by net income and an increase in advance payments from customers.
Advanced payments from customers increased due to higher sales of service
maintenance contracts, which are typically billed at the beginning of the
contract term and recognized as revenue over the service period. Cash used in
investing activities was $138.5

<P align="left" style="font-size: 10pt">million for the six months ended March&nbsp;31, 2004 compared to $17.1&nbsp;million
for the same period in the prior year. The increase was primarily due to
investing the proceeds of the offering and the acquisition of capital
equipment. Cash provided by financing activities for the six months ended
March&nbsp;31, 2004 was $131.4&nbsp;million compared to $4.2&nbsp;million for the same period
in the prior year. Our financing activities consisted of $113.6&nbsp;million net
proceeds received from a public stock offering as well as cash received from
the exercise of employee stock options and purchases under our employee stock
purchase plan. Based on our current operating and capital expenditure
forecasts, we believe that our existing cash and investment balances together
with cash generated from operations should be sufficient to meet our operating
requirements for the foreseeable future.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As of March&nbsp;31, 2004, our principal commitments consisted of obligations
outstanding under operating leases. In 2000, we entered into lease agreements
on two buildings for our corporate headquarters. The lease agreements expire
in 2012 with an option for renewal. The lease for the second building has been
fully subleased through 2012. We established a restricted escrow account in
connection with the lease agreements. Under the lease terms, a $6.0&nbsp;million
letter of credit is required through November&nbsp;2012, unless the lease is
terminated before then. The letter of credit is fully collateralized by a $6.0
million certificate of deposit that has been included on our balance sheet as a
component of restricted cash.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We outsource the manufacturing of our pre-configured hardware platforms to
contract manufacturers who assemble each product to our specifications. Our
agreement with our largest contract manufacturer allows them to procure
component inventory on our behalf based upon a rolling production forecast. We
are contractually obligated to purchase the component inventory in accordance
with the forecast, unless we give notice of order cancellation outside of
applicable lead times. As of March&nbsp;31, 2004, we were committed to purchase
approximately $6.1&nbsp;million of such inventory over the next two quarters.

<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>Interest Rate Risk. </I>The primary objective of our investment activities is
to preserve principal, while at the same time maximize the income we receive
from our investments without significantly increasing risk. Some of the
securities that we have invested in may be subject to market risk. This means
that a change in prevailing interest rates may cause the principal amount of
the investment to fluctuate. For example, if we hold a security that was
issued with a fixed interest rate at the then-prevailing rate and the
prevailing interest rate later rises, the principal amount of our investment
will probably decline. To minimize this risk, we maintain our portfolio of
cash equivalents and investments in a variety of securities, including
commercial paper, government securities and money market funds.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The following table presents the amounts of our cash equivalents,
short-term investments and long-term investments that are subject to market
risk by range of expected maturity and weighted-average interest rates as of
March&nbsp;31, 2004.

denominated in U.S. dollars. While we have conducted some transactions in
foreign currencies during the three and six months ended March&nbsp;31, 2004 and
expect to continue to do so, we do not anticipate that foreign currency
transaction gains or losses will be significant. We have not engaged in
foreign currency hedging to date, however we may do so in the future.

<P align="left" style="font-size: 10pt"><B>Item&nbsp;4. Controls and Procedures</B>


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As of March&nbsp;31, 2004, we carried out an evaluation, under the supervision
and with the participation of the Company&#146;s management, including our Chief
Executive Officer and Chief Financial Officer, of the effectiveness of the
design and operation of our disclosure controls and procedures pursuant to
Exchange Act Rule&nbsp;13a-15(e) and 15d-15(e). Based upon that evaluation, the
Chief Executive Officer and the Chief Financial Officer concluded that our
disclosure controls and procedures are effective to timely alert them to any
material information relating to the Company (including its consolidated
subsidiaries) that must be included in our periodic SEC filings. There have
been no significant changes in the Company&#146;s internal controls or in other
factors that could significantly affect internal controls subsequent to their
evaluation.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We intend to review and evaluate the design and effectiveness of our
disclosure controls and procedures on an ongoing basis and to improve our
controls and procedures over time and to correct any deficiencies that we may
discover in the future. Our goal is to ensure that our senior management has
timely access to all material financial and non-financial information
concerning our business. While we believe the present design of our disclosure
controls and procedures is effective to achieve our goal, future events
affecting our business may cause us to modify our disclosure controls and
procedures.

<P align="left" style="font-size: 10pt"><B>Item&nbsp;1. Legal Proceedings</B>


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company is not aware of any pending legal proceedings that,
individually or in the aggregate, would have a material adverse effect on the
Company&#146;s business, operating results, or financial condition. The Company may
in the future be party to litigation arising in the ordinary course of
business, including claims that allegedly infringe upon third-party trademarks
or other intellectual property rights. Such claims, even if not meritorious,
could result in the expenditure of significant financial and managerial
resources.


<P align="left" style="font-size: 10pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Reference is made to Item&nbsp;3, Legal Proceedings in our Annual Report on
Form 10-K for the year ended September&nbsp;30, 2003, filed October&nbsp;30, 2003, for
descriptions of our legal proceedings. We continue to believe that the
resolution of these legal proceedings will not have a material adverse effect
on us and there have been no material developments since our 10-K filing.

Exhibit 31.1

                                 CERTIFICATIONS

I, John McAdam, certify that:

      1)    I have reviewed this quarterly report on Form 10-Q of F5 Networks,
            Inc.;

      2)    Based on my knowledge, this report does not contain any untrue
            statement of a material fact or omit to state a material fact
            necessary to make the statements made, in light of the circumstances
            under which such statements were made, not misleading with respect
            to the period covered by this report;

      3)    Based on my knowledge, the financial statements, and other financial
            information included in this report, fairly present in all material
            respects the financial condition, results of operations and cash
            flows of the registrant as of, and for, the periods presented in
            this report;

      4)    The registrant's other certifying officer and I are responsible for
            establishing and maintaining disclosure controls and procedures (as
            defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the
            registrant and have:

            a.    designed such disclosure controls and procedures, or caused
                  such disclosure controls and procedures to be designed under
                  our supervision, to ensure that material information relating
                  to the registrant, including its consolidated subsidiaries, is
                  made known to us by others within those entities, particularly
                  during the period in which this report is being prepared;

            b.    evaluated the effectiveness of the registrant's disclosure
                  controls and procedures and presented in this report our
                  conclusions about the effectiveness of the disclosure controls
                  and procedures, as of the end of the period covered by this
                  report based on such evaluation; and

            c.    disclosed in this report any change in the registrant's
                  internal controls over financial reporting that occurred
                  during our most recent fiscal quarter that has materially
                  affected, or is reasonably likely to materially affect, the
                  registrant's internal controls over financial reporting; and

      5)    The registrant's other certifying officer and I have disclosed,
            based on our most recent evaluation, to the registrant's auditors
            and the audit committee of registrant's board of directors (or
