<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;F5 Networks, Inc. (the &#147;Company&#148;) provides products and services to help companies efficiently
and securely manage their Internet Protocol (IP)&nbsp;traffic. The Company&#146;s products improve the
performance, availability and security of applications running on Internet-based networks. Internet
traffic between servers running applications and clients using these applications passes through
the Company&#146;s products where the content is inspected to ensure that it is safe and modified as
necessary to ensure that it is delivered securely and in a way that optimizes the performance of
both the network and the applications. The Company also offers a broad range of services such as
consulting, training, installation, maintenance, and other technical support services.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&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 statement 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

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company&#146;s products are integrated with software that is essential to the functionality of
the equipment. Accordingly, 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 (&#147;SFAS&#148;) No.&nbsp;48, &#147;Revenue Recognition When Right of
Return Exists,&#148; and SEC Staff Accounting Bulletin (&#147;SAB&#148;) No.&nbsp;104, &#147;Revenue Recognition.&#148;
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&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 reasonably assured and no significant performance obligations remain. In certain
regions where the Company does not have the ability to reasonably estimate returns, the Company
defers revenue on sales to its distributors until they have received information from the channel
partner indicating that the distributor has sold the product to its customer. Payment terms to
domestic customers are generally net 30 to 45&nbsp;days. Payment terms to international customers range
from net 30 to net 90&nbsp;days based on normal and customary trade practices in the individual markets.
The Company offers extended payment terms to certain customers, in which case, revenue is
recognized when payments are received.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Whenever a software license, hardware, installation and post-contract customer support (&#147;PCS&#148;)
elements are sold together, a portion of the sales price is allocated to each element 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 the Company
cannot estimate returns, it recognizes revenue when such rights of return lapse. Revenues for PCS
are recognized on a straight-line basis over the service contract term. PCS includes a limited
period of telephone support updates, bug fixes and rights to upgrades, when and if available.
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.

<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>Stock-Based Compensation</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company accounts for stock-based compensation in accordance with Financial Accounting
Standards Board (&#147;FASB&#148;) Statement No.&nbsp;123(R), <I>Share-Based Payment </I>(&#147;FAS 123R&#148;), using the
straight-line attribution method for recognizing compensation expense. The Company recognized $8.7
million and $5.3&nbsp;million of stock-based compensation expense for the three months ended December
31, 2006 and 2005, respectively. As of December&nbsp;31, 2006, there was $46.6&nbsp;million of total
unrecognized stock-based compensation cost, the majority of which will be recognized over the next
two years. Going forward, stock-based compensation expenses may increase as we issue additional
equity-based awards to continue to attract and retain key employees.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company issues incentive awards to its employees through stock-based compensation
consisting of stock options and restricted stock units (&#147;RSU&#146;s&#148;). The value of RSU&#146;s is determined
using the intrinsic value method, which in this case, is based on the number of shares granted and
the quoted price of the Company&#146;s common stock on the date of grant. Alternatively, in determining
the fair value of stock options, the Company uses the Black-Scholes option pricing model that
employs the following key assumptions. Expected volatility is based on the annualized daily
historical volatility of the Company&#146;s stock price over the expected life of the option. Expected
term of the option is based on historical employee stock option exercise behavior, the vesting
terms of the respective option and a contractual life of ten years. The Company&#146;s stock price
volatility and option lives involve management&#146;s best estimates at that time, both of which impact
the fair value of the option calculated under the Black-Scholes methodology and, ultimately, the
expense that will be recognized over the life of the option.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;FAS 123R also requires that the Company recognize compensation expense for only the portion of
stock options or RSU&#146;s that are expected to vest. Therefore, the Company applies estimated
forfeiture rates that are derived from historical employee termination behavior. The Company&#146;s
estimated forfeiture rate in the first quarter of fiscal 2007 is 5%. If the actual number of
forfeitures differs from those estimated by management, additional adjustments to stock-based
compensation expense may be required in future periods.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Compensation cost recognized for the three month period ended December&nbsp;31, 2006 includes: (a)
compensation cost for all share-based payments granted prior to, but not yet vested as of July&nbsp;1,
2005, based on the grant-date fair value estimated in accordance with the original provisions of
FASB Statement No.&nbsp;123, <I>Accounting for Stock-Based Compensation </I>and (b)&nbsp;compensation cost for all
share-based payments granted subsequent to July&nbsp;1, 2005, based on the grant-date fair value
estimated in accordance with the provisions of FAS 123R.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In December&nbsp;2006, the Company granted 228,000 RSU&#146;s to certain current executive officers.
Fifty percent of the aggregate number of RSU&#146;s granted at such time vest in equal quarterly
increments over two years, until such portion of the grant is fully vested on November&nbsp;1, 2008.
Twenty five percent of the RSU grant is subject to the Company achieving specified percentage
increases in total revenue for fiscal year 2007, relative to fiscal year 2006. The remaining
twenty five percent is subject to the Company meeting specified performance criteria for fiscal
year 2008 to be set by the Compensation Committee of the Company&#146;s Board of Directors.

<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>Earnings Per Share</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Basic net income per share is computed by dividing net income by the weighted average number
of common shares outstanding during the period. Diluted net income per share is computed by
dividing net income by the weighted average number of common and dilutive common stock equivalent
shares outstanding during the period.

which defines fair value, establishes a framework for measuring fair value and expands disclosures
about fair value measurements. SFAS 157 is effective for fiscal years beginning after November&nbsp;15,
2007, and interim periods within those fiscal years. The Company is currently assessing the
potential effect if any of implementing this standard.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In September&nbsp;2006, the SEC issued, No.&nbsp;108, <I>&#147;Considering the Effects of Prior Year
Misstatements when Quantifying Misstatements in Current Year Financial Statements&#148; </I>(&#147;SAB 108&#148;),
which is effective for fiscal years ending after November&nbsp;15, 2006. SAB 108 provides interpretive
guidance on the consideration of the effects of prior year misstatements in quantifying current
year misstatements for the purpose of a materiality assessment. We do not expect the adoption of
SAB 108 to have a material impact on our consolidated financial statements.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In June&nbsp;2006, the FASB issued FIN, No.&nbsp;48, <I>&#147;Accounting for Uncertainty in Income Taxes&#148; </I>(&#147;FIN
48&#148;). FIN 48 clarifies the application of SFAS No.&nbsp;109 by providing detailed guidance for the
financial statement recognition, measurement and disclosure of uncertain tax positions recognized
in an enterprise&#146;s financial statements. Tax positions must meet a more-likely-than-not recognition
threshold at the effective date to be recognized upon the adoption of FIN 48 and in subsequent
periods. FIN 48 will be effective for fiscal years beginning after December&nbsp;15, 2006. We are
currently evaluating the potential effects, if any, of FIN 48 on its consolidated financial
statements.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In the normal course of business to facilitate sales of the Company&#146;s products, the Company
indemnifies other parties, including customers, resellers, lessors, and parties to other
transactions with them, 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 their officers and
directors, and their bylaws contain similar indemnification obligations to the Company&#146;s agents. It
is not possible to determine the maximum potential amount under these indemnification agreements
due to the limited history of prior indemnification claims and the unique facts and circumstances
involved in each particular agreement.

manufacturer procures in accordance with the forecast, unless they give notice of order

2004 fiscal years. The Company has produced documents and other information to the IRS and is

against certain current and former directors and officers of the Company. These derivative lawsuits
were filed in: (1)&nbsp;the Superior Court of King County, Washington, as Adams v. Amdahl, et al. (Case
No.&nbsp;06-2-17195-1 SEA), Wright v. Amdahl, et al. (Case No.&nbsp;06-2-19159-5 SEA), and Sommer v. McAdam,
et al. (Case No.&nbsp;06-2-26248-4 SEA); and (2)&nbsp;in the U.S. District Court for the Western District of
Washington, as In re F5 Networks, Inc. Derivative Litigation, Master File No.&nbsp;C06-0794RSL, which
consolidates Hutton v. McAdam, et al. (Case No.&nbsp;06-794RSL), Locals 302 and 612 of the International
Union of Operating Engineers-Employers Construction Industry Retirement Trust v. McAdam et al.
(Case No.&nbsp;C06-1057RSL), and Easton v. McAdam et al. (Case No.&nbsp;C06-1145RSL). The complaints
generally allege that certain of the Company&#146;s current and former directors and officers,
including, in general, each of the Company&#146;s current outside directors (other than Deborah L.
Bevier who joined the Company&#146;s Board of Directors in July&nbsp;2006) breached their fiduciary duties to
the Company by engaging in alleged wrongful conduct concerning the manipulation of certain stock
option grant dates. The Company is named solely as a nominal defendant against whom the plaintiffs
seek no recovery. Although litigation is subject to inherent uncertainties, the Company does not
believe the results of these pending actions will, individually or in the aggregate, have a
material adverse impact on the consolidated financial position or results of operations.

actions arising in relation to our historical stock option practices and the restatement of our
prior period financial statements. Although regulatory proceedings are subject to inherent
uncertainties, the Company does not believe the results of any pending actions will, individually
or in the aggregate, have a material adverse impact on the consolidated financial position or
results of operations.

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

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The effective tax rate was 33.3% and 38.5% for the three months ended December&nbsp;31, 2006 and
2005, respectively. On December&nbsp;20, 2006 the President of the United States signed into law the
&#147;2006 Tax Relief and Health Care Act.&#148; The law reinstated the tax credit for increasing research
activities retroactively for qualifying expenses paid or incurred after December&nbsp;31, 2005 and
before January&nbsp;1, 2008. Prior to the President&#146;s signing into law this Act the tax credit for
increasing research activities had expired on December&nbsp;31, 2005. As a result of the retroactive
reinstatement of the tax credit for increasing research activities for qualifying expenses paid or
incurred after December&nbsp;31, 2005 the Company realized a one time benefit in its effective tax rate
of 4.8%. Excluding this one time benefit the Company would have recorded a 38.1% provision for
income taxes during the current period. The current extension of the tax credit is for two years
but legislation has extended these tax credits for relatively short periods of time in the past.

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Operating segments are defined as components of an enterprise for which separate financial
information is available and evaluated regularly by the chief operating decision-maker, or
decision-making group, in deciding how to allocate resources and in assessing performance. The
Company is organized as, and operates in, one reportable segment: the development, marketing and
selling of a comprehensive suite of application networking solutions that helps customers
efficiently and securely manage application traffic on their Internet-based networks. The Company
manages its business based on four geographic regions: the Americas (primarily the United States);
Europe, the Middle East and Africa (EMEA); Japan; and the Asia Pacific region. The Company&#146;s chief
operating decision-making group reviews financial information presented on a consolidated basis
accompanied by information about revenues by geographic region. The Company&#146;s foreign offices
conduct sales, marketing and support activities. The Company&#146;s management evaluates performance
based primarily on revenues in the geographic locations in which it operates. Revenues are
attributed by geographic location based on the location of the customer. The Company&#146;s assets are
primarily located in the United States and not allocated to any specific region. Therefore,
geographic information is presented only for net product revenue.

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

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&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:
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%"><B><I><B>&#149;</B> </I></B><I>Revenues. </I>The majority of our revenues are derived from sales of our core products; BIG-IP
Local Traffic Manager; BIG-IP Global Traffic Manager; BIG-IP ISP Traffic Manager; TrafficShield
Application Firewall, WANJet, WebAccelerator; 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 revenues within each
reporting period. We believe customer acceptance rates of our new products and feature
enhancements are key indicators of future trends. We also consider overall revenue concentration
by customer and by geographic region as additional indicators of current and future trends.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%"><B><I><B>&#149;</B> </I></B><I>Cost of revenues and gross margins. </I>We strive to control our cost of revenues and thereby
maintain our gross margins. Significant items impacting cost of revenues are hardware costs paid
to our contract manufacturers, third-party software license fees, amortization of developed
technology, and personnel and overhead expenses. Our margins have remained relatively stable
over the past two years; however factors such as sales price, product mix, inventory
obsolescence, returns, component price increases, and warranty costs could significantly impact
our gross margins from quarter to quarter and represent the significant indicators we monitor on
a regular basis.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%"><B><I><B>&#149;</B> </I></B><I>Operating expenses. </I>Operating expenses are substantially driven by personnel and related
overhead expenses. Existing headcount and future hiring plans are the predominant factors in
analyzing and forecasting future operating expense trends. Other significant operating expenses
that we monitor include marketing and promotions, travel, professional fees, computer costs
related to the development of new products, facilities and depreciation expenses.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%"><B><I><B>&#149;</B> </I></B><I>Liquidity and cash flows. </I>Our financial condition remains strong with significant cash and
investments and no long term debt. The increase in cash and investments for the first three
months of fiscal year 2007 was primarily due to net income from operations, with operating
activities providing cash of $46.8&nbsp;million. Going forward, we believe the primary driver of cash
flows will be net income from operations. Capital expenditures for the first three months of
fiscal year 2007 were comprised primarily of tenant improvements and information technology
infrastructure and equipment to support the growth of our core business activities.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 2%"><B><I><B>&#149;</B> </I></B><I>Balance sheet. </I>We view cash, short-term and long-term investments, deferred revenue, accounts
receivable balances and day&#146;s sales outstanding as important indicators of our financial health.
Deferred revenues continued to increase due to the growth in the amount of annual maintenance
contracts purchased on new products and maintenance renewal contracts related to our existing
product installation base. Our day&#146;s sales outstanding for the first quarter of fiscal year 2007
was 50. We expect to maintain this metric in the low to mid 50&nbsp;day range going forward.

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The preparation of our financial condition and results of operations requires us to make
judgments and estimates that may have a significant impact upon our financial results. We believe
that, of our significant accounting policies, the following require estimates and assumptions that
require complex, subjective judgments by management, which can materially impact reported results:
revenue recognition; reserve for doubtful accounts; reserve for product returns; reserve for
warranties; accounting for income taxes; stock-based compensation; and goodwill impairment. Each of
these accounting policies and estimates , which nave not significantly changed since our annual
report on Form 10-K for the year ended September&nbsp;30, 2006 (the &#147;Form 10-K&#148;), are more fully
described in &#147;Management&#146;s Discussion and Analysis of Financial Condition and Results of
Operations&#148; in the Form 10-K. Actual results may differ from these estimates under different
assumptions or conditions.

December&nbsp;31, 2006 from $88.1&nbsp;million for the same period in the prior year. The improvement was due
to increased demand for our application delivery networking products and higher services revenues
resulting from our increased installed base of products. International revenues were 39.6% of total
net revenues for the three months ended December&nbsp;31, 2006 compared to 40.7% for the same period in
the prior year. We expect international sales will continue to represent a significant portion of
net revenues, although we cannot provide assurance that international revenues as a percentage of
net revenues will remain at current levels.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Net product revenues increased 34.2%, to $92.1&nbsp;million for the three months ended December&nbsp;31,
2006 from $68.6&nbsp;million for the same period in the prior year. The increase in the three months
ended December&nbsp;31, 2006, was primarily due to growth in the volume of product sales of our
Application Traffic Management (ATM)&nbsp;product line as well as incremental revenues derived from
sales of our Wide Area Networks (WAN), FirePass and TrafficShield product lines. Sales of our ATM
family of application delivery networking products represented 89.6% and 91.5% of product revenues
for the three months ended December&nbsp;31, 2006 and 2005, respectively.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Net service revenues increased 43.5%, to $28.0&nbsp;million for the three months ended December&nbsp;31,
2006 from $19.5&nbsp;million for the same period in the prior year. The increase in services revenue was
primarily due to increases in the purchase or renewal of maintenance contracts as our installed
base of products increased.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Avnet Technology Solutions and Ingram Micro Inc., two of our domestic distributors, accounted
for 14.1% and 11.8% of our total net revenue for the three months ended December&nbsp;31, 2006,
respectively. Ingram Micro Inc., accounted for 14.9% of our total net revenues for the three month
period ended December&nbsp;31, 2005.

relations, advertising and trade shows, facilities and depreciation expenses. Sales and marketing
expenses increased 35.3% for the three months ended December&nbsp;31, 2006 from the comparable period in
the prior year. The increase in sales and marketing expense was primarily due to increased
commissions and personnel costs of $4.4&nbsp;million and an increase in stock-based compensation expense
of $1.3&nbsp;million. The increased commissions and personnel costs were driven by growth in sales and
marketing employee headcount and increased revenue for the respective periods. Sales and marketing
headcount at the end of December&nbsp;2006 increased to 489 from 380 at the end of December&nbsp;2005. We

our market share.

the comparable period in the prior year. The increase in research and development expenses was
primarily due to increased salary and benefit expenses of $2.1&nbsp;million and an increase in
stock-based compensation expense of $0.9&nbsp;million. Research and development headcount at the end of
December&nbsp;2006 increased to 298 from 245 at the end of December&nbsp;2005. The growth in headcount was
primarily related to enhancement of our current products and our ability to develop new,

continued development of our products.

ended December&nbsp;31, 2006 from the comparable period in the prior year. The increase in general and
administrative expenses was primarily due to expenses incurred by third parties for legal,
accounting, tax and other professional services in connection with the review of our stock option
practices conducted by the special committee of outside directors formed by our Board of Directors
(the &#147;Special Committee&#148;) of $2.6&nbsp;million, an increase in stock-based compensation expense of $1.0
million and increased salary

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>Other income, net. </I>Other income, net, consists of interest income and foreign currency
transaction gains and losses. Other income, net, increased 116.5% compared to the same period in
the prior year. The significant increase was due to a combination of higher yields and increased
investment balances. The increased investment balances are the result of cash provided from
operating and financing activities.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>Provision for Income taxes</I>. We recorded a 33.3% provision for income taxes during the current
period. As of December&nbsp;31, 2006 we do not have a valuation allowance on any of our deferred tax
assets in any of the jurisdictions in which we operate because we believe that these assets are
more likely than not to be realized. In making this determination we have considered projected
future taxable income and ongoing prudent and feasible tax planning strategies in assessing the
appropriateness of a valuation allowance. Our net deferred tax assets at December&nbsp;31, 2006 and
December&nbsp;31, 2005 were $25.1&nbsp;million and $33.5&nbsp;million, respectively. Our world wide effective tax
rate may fluctuate based on a number of factors including variations in projected taxable income in
our geographic locations, changes in the valuation of our net deferred tax assets, resolution of
potential exposures or establishment of potential exposures, introduction of new accounting
standards or changes in tax laws or interpretations thereof in any of our geographic locations.
Significant judgment is required in evaluating our tax positions and determining our provision for
income taxes. During the ordinary course of business, there are many transactions and calculations
for which the ultimate tax determination is uncertain. We establish reserves for tax-related
uncertainties based on judgment of whether, and the extent to which, additional taxes and interest
may be due. These reserves are established when, despite our belief that our tax return positions
are fully supportable, we believe that certain positions may be challenged and may not be sustained
on review by tax authorities. We adjust these reserves in light of changing facts and
circumstances, such as the closing of a tax audit or changes in tax laws or interpretations
thereof. The provision for income taxes includes the impact of reserve provisions and changes to
reserves that are considered appropriate. The ultimate resolution of these potential exposures may
be greater or less than the liabilities recorded which could result in an adjustment to our future
tax expense and a fluctuation in our effective tax rate. On December&nbsp;20, 2006 the President of the
United States signed into law the &#147;2006 Tax Relief and Health Care Act.&#148; The law reinstated the
tax credit for increasing research activities retroactively for qualifying expenses paid or
incurred after December&nbsp;31, 2005 and before January&nbsp;1, 2008. Prior to the President&#146;s signing into
law this Act, the tax credit for increasing research activities had expired on December&nbsp;31, 2005.
As a result of the retroactive reinstatement of the tax credit for increasing research activities
for qualifying expenses paid or incurred after December&nbsp;31, 2005, the Company realized a one time
benefit in its effective tax rate of 4.8%. Excluding this one time benefit, the Company would have
recorded a 38.1% provision for income taxes during the current period. The current extension of the
tax credit is for two years but legislation has extended these tax credits for relatively short
periods of time in the past.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Cash and cash equivalents, short-term investments and long-term investments were $545.3
million as of December&nbsp;31, 2006 compared to $492.2&nbsp;million as of September&nbsp;30, 2006, representing
an increase of $53.1&nbsp;million. The increase was primarily due to cash provided by operating
activities of $46.8&nbsp;million for the three months ended December&nbsp;31, 2006 compared to $34.5&nbsp;million
for the same period in the prior year. The increase in cash flow from operations for the first
three months of fiscal year 2007 resulted from increased net income combined with changes in
operating assets and liabilities, as adjusted for various non-cash items including stock-based
compensation, depreciation and amortization charges. 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.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Cash used in investing activities was $62.2&nbsp;million for the three months ended December&nbsp;31,
2006 compared to $87.6&nbsp;million for the same period in the prior year. The significant amount of
cash used in investing activities for the first three months of fiscal year 2007 was primarily due
to the purchase of investments partially offset by the sale of investments.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Cash provided by financing activities for the three months ended December&nbsp;31, 2006 was $8.7
million compared to $19.9&nbsp;million for the same period in the prior year. Our financing activities
for the three months ended December&nbsp;31, 2006 and 2005 consisted primarily of cash received from the
exercise of employee stock options and purchases under our employee stock purchase plan.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As of December&nbsp;31, 2006, our principal commitments consisted of obligations outstanding under
operating leases. We lease our facilities under operating leases that expire at various dates
through 2012. There have been no material changes in our principal lease commitments compared to
those discussed in the Form 10-K. In connection with the lease agreement for our corporate
headquarters we established a restricted escrow account collateralized by a certificate of deposit
that has been included on our balance sheet as a component of restricted cash. The total amount
required in escrow reduces at various dates as set forth by the lease agreement. The amount
required in escrow at December&nbsp;31, 2006 was $3.6&nbsp;million as set forth by the lease agreement.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&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 in advance of applicable
lead times. As of December&nbsp;31, 2006, we were committed to purchase approximately $15.0&nbsp;million of
such inventory during the next quarter.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We expect the application delivery networking market to be characterized by rapid
technological change, frequent new product introductions, changes in customer requirements and

new products and new features for our existing products to meet the demands of these changes, and
for those products and features to be accepted by our existing and target customers. If we are

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

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In September&nbsp;2004, we announced the release of our next-generation BIG-IP product featuring
the Traffic Management Operating System, or TMOS. This major new version of BIG-IP represented the
culmination of over two years of research and development efforts. TMOS is specifically designed to
facilitate the development and integration of application delivery functions as modules that can be
added to BIG-IP&#146;s core functionality to keep pace with rapidly evolving customer needs. We
currently offer software modules as add-ons for this product and our continued success depends
significantly on our ability to integrate new modules and functionality onto this platform and the
acceptance of the new hardware and software platforms associated with this release by our existing
and target customers.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The current life cycle of our products is typically 12 to 24&nbsp;months. The introduction of new
products or product enhancements may shorten the life cycle of our existing products, or replace
sales of some of our current products, thereby offsetting the benefit of even a successful product
introduction, and may cause customers to defer purchasing our existing products in anticipation of
the new products. This could harm our operating results by decreasing sales, increasing our
inventory levels of older products and exposing us to greater risk of product obsolescence. We have
also experienced, and may in the future experience, delays in developing and releasing new products
and product enhancements. This has led to, and may in the future lead to, delayed sales, increased
expenses and lower quarterly revenue than anticipated. Also, in the development of our products, we
have experienced delays in the prototyping of our products, which in turn has led to delays in
product introductions. In addition, complexity and difficulties in managing product transitions at
the end-of-life stage of a product can create excess inventory of components associated with the
outgoing product that can lead to increased expenses. Any or all of the above problems could
materially harm our business and operating results.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>Our success depends on sales and continued innovation of our BIG-IP product lines</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;For the fiscal year ended September&nbsp;30, 2006, we derived 89.4% of our product revenues from
sales of our BIG-IP family of application delivery networking product lines. We expect to derive a
significant portion of our net revenues from sales of our BIG-IP products in the future.
Implementation of our strategy depends upon BIG-IP being able to solve critical network
availability and performance problems of our customers. If BIG-IP is unable to solve these problems
for our customers or if we are unable to sustain the high levels of innovation in BIG-IP&#146;s product
feature set needed to maintain leadership in what will continue to be a competitive market
environment, our business and results of operations will be harmed.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>We may not be able to compete effectively in the emerging application delivery networking market</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The markets we serve are new, rapidly evolving and highly competitive, and we expect
competition to persist and intensify in the future. Our principal competitors in the application
delivery networking market include Cisco Systems, Inc., Nortel Networks Corporation, Foundry
Networks, Inc., Citrix Systems, Inc., Radware Ltd. and Juniper Networks, Inc. We expect to continue
to face additional competition as new participants enter our market. In addition, larger companies
with significant resources, brand recognition and sales channels may form alliances with or acquire
competing application delivery networking solutions and emerge as significant competitors.
Potential competitors may bundle their products or incorporate an Internet traffic management or
security component into existing products in a manner that discourages users from purchasing our
products.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>Our quarterly and annual operating results are volatile and may cause our stock price to fluctuate</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our quarterly and annual operating results have varied significantly in the past and will vary
significantly in the future, which makes it difficult for us to predict our future operating
results. In particular, we anticipate that the size of customer orders may increase as we continue
to focus on larger business accounts. A delay in the recognition of revenue, even from just one
account, may have a significant negative impact on our results of operations for a given period. In
the past, a majority of our sales have been realized near the end of a quarter. Accordingly, a
delay in an anticipated sale past the end of a particular quarter may negatively impact our results
of operations for that quarter, or in some cases, that year. Additionally, we have exposure to the
credit risks of some of our customers and sub-tenants. Although we have programs in place that are
designed to monitor and mitigate the associated risk, there can be no assurance that such programs
will be effective in reducing our credit risks adequately. We monitor individual payment capability
in granting credit arrangements, seek to limit the total credit to amounts we believe our customers
can pay, and maintain reserves we believe are adequate to cover exposure for potential losses. If
there is a deterioration of a sub-tenant&#146;s or major customer&#146;s creditworthiness or actual defaults
are higher than expected future resulting losses, if incurred, could harm our business and have a
material adverse effect on our operating results.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Further, our operating results may be below the expectations of securities analysts and
investors in future quarters or years. Our failure to meet these expectations will likely harm the
market price of our common stock.
</DIV>
<DIV align="left" style="font-size: 10pt; margin-top: 6pt"><B>The average selling price of our products may decrease and our costs may increase, which may
negatively impact gross profits</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;It is possible that the average selling prices of our products will decrease in the future in
response to competitive pricing pressures, increased sales discounts, new product introductions by
us or our competitors or other factors. Therefore, in order to maintain our gross profits, we must
develop and introduce new products and product enhancements on a timely basis and continually
reduce our product costs. Our failure to do so will cause our net revenue and gross profits to
decline, which will harm our business and results of operations. In addition, we may experience
substantial period-to-period fluctuations in future operating results due to the erosion of our
average selling prices.
</DIV>
<DIV align="left" style="font-size: 10pt; margin-top: 6pt"><B>It is difficult to predict our future operating results because we have an unpredictable sales
cycle</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our products have a lengthy sales cycle, which is difficult to predict. Historically, our
sales cycle has ranged from approximately two to three months and has tended to lengthen as we have
increasingly focused our sales efforts on the enterprise market. Also, as our distribution strategy
has evolved into more of a channel model, utilizing value-added resellers, distributors and systems
integrators, the level of variability in the length of sales cycle across transactions has
increased and made it more difficult to predict the timing of many of our sales transactions. Sales
of our products require us to educate potential customers in their use and benefits. Sales of our
products are subject to delays from the lengthy internal budgeting, approval and competitive
evaluation processes that large corporations and governmental entities may require. For example,
customers frequently begin by evaluating our products on a limited basis and devote time and
resources to testing our products before they decide whether or not to purchase. Customers may also
defer orders as a result of anticipated releases of new products or enhancements by our competitors
or us. As a result, our products have an unpredictable sales cycle that contributes to the
uncertainty of our future operating results.
</DIV>
<DIV align="left" style="font-size: 10pt; margin-top: 6pt"><B>Our business may be harmed if our contract manufacturers are not able to provide us with adequate
supplies of our products or if a single source of hardware assembly is lost or impaired</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We rely on third party contract manufacturers to assemble our products. We outsource the
manufacturing of our hardware platforms to contract manufacturers who assemble these hardware
platforms to our specifications. We have experienced minor delays in shipments from contract
manufacturers in the past. However, if we experience major delays in the future or other problems,
such as inferior quality and insufficient quantity of product, any one or a combination of these
factors may harm our business and results of operations. The inability of our contract
manufacturers to provide us with adequate supplies of our products or the loss of our contract
manufacturer may cause a delay in our ability to fulfill orders while we obtain a replacement
manufacturer and may harm our business and results of operations. In particular, because we
subcontract substantially all of our manufacturing to a single contract manufacturer, with whom we
do not have a long-term contract, any termination, loss or impairment in our arrangement with this
single source of hardware assembly, or any impairment of their facilities or operations, would harm
our business, financial condition and results of operation.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;If the demand for our products grows, we will need to increase our raw material and component
purchases, contract manufacturing capacity and internal test and quality control functions. Any
disruptions in product flow may limit our revenue, may harm our competitive position and may result
in additional costs or cancellation of orders by our customers.
</DIV>
<DIV align="left" style="font-size: 10pt; margin-top: 6pt"><B>Our business could suffer if there are any interruptions or delays in the supply of hardware
components from our third-party sources</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We currently purchase several hardware components used in the assembly of our products from a
number of single or limited sources. Lead times for these components vary significantly. The
unavailability of suitable components, any interruption or delay in the supply of any of these
hardware components, or the inability to procure a similar component from alternate sources at
acceptable prices within a reasonable time, may delay assembly and sales of our products and,
hence, our revenues, and may harm our business and results of operations.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt"><B>We may not adequately protect our intellectual property and our products may infringe on the
intellectual property rights of third parties</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We rely on a combination of patent, copyright, trademark and trade secret laws and
restrictions on disclosure of confidential and proprietary information to protect our intellectual
property rights. Despite our efforts to protect our proprietary rights, unauthorized parties may
attempt to copy or otherwise obtain and use our products or technology. Monitoring unauthorized use
of our products is difficult, and we cannot be certain that the steps we have taken will prevent
misappropriation of our technology, particularly in foreign countries where the laws may not
protect our proprietary rights as fully as in the United States.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our industry is characterized by the existence of a large number of patents and frequent
claims and related litigation regarding patent and other intellectual property rights. In the
ordinary course of our business, we are involved in disputes and licensing discussions with others
regarding their claimed proprietary rights and cannot assure you that we will always successfully
defend ourselves against such claims. If we are found to infringe the proprietary rights of others,
or if we otherwise settle such claims, we could be compelled to pay damages or royalties and either
obtain a license to those intellectual property rights or alter our products so that they no longer
infringe upon such proprietary rights. Any license could be very expensive to obtain or may not be
available at all. Similarly, changing our products or processes to avoid infringing the rights of
others may be costly or impractical. In addition, we have initiated, and may in the future
initiate, claims or litigation against third parties for infringement of our proprietary rights, to
determine the scope and validity of our proprietary rights or those of our competitors. Any of
these claims, whether claims that we are infringing the proprietary rights of others, or vice
versa, with or without merit, may be time-consuming, result in costly litigation and diversion of
technical and management personnel or require us to cease using infringing technology, develop
non-infringing technology or enter into royalty or licensing agreements. Further, our license
agreements typically require us to indemnify our customers, distributors and resellers for
infringement actions related to our technology, which could cause us to become involved in
infringement claims made against our customers, distributors or resellers. Any of the
above-described circumstances relating to intellectual property rights disputes could result in our
business and results of operations being harmed.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Many of our products include intellectual property licensed from third parties. In the future,
it may be necessary to renew licenses for third party intellectual property or obtain new licenses
for other technology. These third party licenses may not be available to us on acceptable terms, if
at all. The inability to obtain certain licenses, or litigation regarding the interpretation or
enforcement of license rights and related intellectual property issues, could have a material
adverse effect on our business, operating results and financial condition. Furthermore, we license
some third party intellectual property on a non-exclusive basis and this may limit our ability to
protect our intellectual property rights in our products.
</DIV>
<DIV align="left" style="font-size: 10pt; margin-top: 6pt"><B>We may not be able to sustain or develop new distribution relationships and a reduction or delay in
sales to a significant distribution partner could hurt our business</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our sales strategy requires that we establish and maintain multiple distribution channels in
the United States and internationally through leading industry resellers, systems integrators,
Internet service providers and other channel partners. We have a limited number of agreements with
companies in these channels, and we may not be able to increase our number of distribution
relationships or maintain our existing relationships. If we are unable to establish or maintain our
indirect sales channels, our business and results of operations will be harmed. In addition, one
domestic distributor of our products accounted for 13.6% and 18.6% of our total net revenue for the
fiscal years 2006 and 2005, respectively. A substantial reduction or delay in sales of our products
to this or any other key distribution partner could harm our business, operating results and
financial condition.

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Software products frequently contain undetected errors when first introduced or as new
versions are released. We have experienced these errors in the past in connection with new products
and product upgrades. We expect that these errors will be found from time to time in new or
enhanced products after commencement of commercial shipments. These problems may cause us to incur
significant warranty and repair costs, divert the attention of our engineering personnel from our
product development efforts and cause significant customer relations problems. We

subject to liability claims for damages related to product errors. While we carry insurance
policies
covering this type of liability, these policies may not provide sufficient protection should a
claim be asserted. A material product liability claim may harm our business and results of
operations.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our products must successfully operate with products from other vendors. As a result, when
problems occur in a network, it may be difficult to identify the source of the problem. The
occurrence of software errors, whether caused by our products or another vendor&#146;s products, may
result in the delay or loss of market acceptance of our products. The occurrence of any of these
problems may harm our business and results of operations.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>Our operating results are exposed to risks associated with international commerce</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As our international sales increase, our operating results become more exposed to
international operating risks. These risks include risks related to potential recessions in
economies outside the United States, foreign currency exchange rates, managing foreign sales
offices, regulatory, political, or economic conditions in specific countries, military conflict or
terrorist activities, changes in laws and tariffs, inadequate protection of intellectual property
rights in foreign countries, foreign regulatory requirements, and natural disasters. All of these
factors could have a material adverse effect on our business. We intend to continue expanding into
international markets. International sales represented 42.6% and 40.5% of our net revenues for the
fiscal years ended September&nbsp;30, 2006 and 2005, respectively. In particular, in fiscal year 2006,
we derived 13.1% of our total revenue from the Japanese market. This revenue is dependent on a
number of factors outside our control, including the viability and success of our resellers and the
strength of the Japanese economy.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>Changes in governmental regulations could negatively affect our revenues</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our products are subject to various regulations promulgated by the United States and various
foreign governments including, but not limited to, environmental regulations and regulations
implementing export license requirements and restrictions on the import or export of some
technologies, especially encryption technology. Changes in governmental regulation and our
inability or failure to obtain required approvals, permits or registrations could harm our
international and domestic sales and adversely affect our revenues, business and operations.
</DIV>
<DIV align="left" style="font-size: 10pt; margin-top: 6pt"><B>Acquisitions, including our recent acquisition of Swan Labs Corporation, present many risks and we
may not realize the financial and strategic goals that are contemplated at the time of the
transaction</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;With respect to our acquisitions, as well as any other future acquisitions we may undertake,
we may find that the acquired assets do not further our business strategy as expected, or that we
paid more than what the assets are later worth, or that economic conditions change, all of which
may generate future impairment charges. There may be difficulty integrating the operations and
personnel of the acquired business, and we may have difficulty retaining the key personnel of the
acquired business. We may have difficulty in incorporating the acquired technologies or products
with our existing product lines. Our ongoing business and management&#146;s attention may be disrupted
or diverted by transition or integration issues and the complexity of managing geographically and
culturally diverse locations. We may have difficulty maintaining uniform standards, controls,
procedures and policies across locations. We may experience significant problems or liabilities
associated with the product quality, technology and other matters.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our inability to successfully operate and integrate newly-acquired businesses appropriately,
effectively and in a timely manner, or to retain key personnel of any acquired business, could have
a material adverse effect on our ability to take advantage of further growth in demand for
integrated traffic management and security solutions and other advances in technology, as well as
on our revenues, gross margins and expenses.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our success depends to a significant degree upon the continued contributions of our key
management, product development, sales, marketing and finance personnel, many of whom may be
difficult to replace. The complexity of our application delivery networking products and their

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We are a party to lawsuits in the normal course of our business. Litigation in general and
intellectual property and securities litigation in particular, can be expensive, lengthy and
disruptive to normal business operations. Moreover, the results of complex legal proceedings are
difficult to predict. Responding to the allegations has been, and will likely continue to be,
expensive and time-consuming for us. An unfavorable resolution of the lawsuits could adversely
affect our business, results of operations, or financial condition.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our historical stock option practices and the restatement of our prior financial statements
have exposed us to greater risks associated with litigation. In May&nbsp;2006, several derivative

adverse resolution of any lawsuit could have a material adverse effect on our business, financial
condition and results of operations. We cannot assure you that any future litigation relating to
our historical stock option practices will result in the same conclusions reached by the Special

historical stock option practices. Upon completion of its review, the Special Committee found that
the recorded grant dates for certain stock options granted during fiscal years 1999 to 2004 should
not be relied upon as the measurement date for accounting purposes and the accounting treatment
used for the vesting of certain stock options was incorrect. Based on the Special Committee&#146;s
review, to correct the accounting treatment, we have amended our Quarterly Reports on Form 10-Q for
the three months ended December&nbsp;31, 2005 and March&nbsp;31, 2006 and our Annual Report on Form 10-K/A
(as amended) for the year ended September&nbsp;30, 2005, to restate the consolidated financial
