                   SPECIAL NOTE ON FORWARD-LOOKING STATEMENTS

This document contains forward-looking statements that involve risks and
uncertainties. The Company's operating results may vary significantly from
quarter to quarter due to a variety of factors, including changes in the
Company's product and customer mix, constraints in the Company's manufacturing
and assembling operations, shortages or increases in the prices of raw materials
and components, changes in pricing policy by the Company or its competitors, a
slowdown in the growth of the networking market, seasonality, timing of
expenditures and economic conditions in the United States, Europe and Asia.
Words such as "believes," "anticipates," "expects," "intends" and similar
expressions are intended to identify forward-looking statements, but are not the
exclusive means of identifying such statements. Unless the context otherwise
requires, references in this Form 10-Q to "we," "us," or the "Company" refer to
Castelle. Readers are cautioned that the forward-looking statements reflect
management's analysis only as of the date hereof, and the Company assumes no
obligation to update these statements. Actual events or results may differ
materially from the results discussed in the forward-looking statements. Factors
that might cause such a difference include, but are not limited to the risks and
uncertainties discussed herein, as well as other risks set forth under the
caption "Risk Factors" in the Company's Annual Report on Form 10-K and Form
10-K/A for the fiscal year ended December 31, 2000.

              Notes To Condensed Consolidated Financial Statements
                                   (unaudited)

1.       Basis of Presentation:

     The accompanying unaudited consolidated financial statements include the
     accounts of Castelle and its wholly-owned subsidiaries in the United
     Kingdom and the Netherlands, and have been prepared in accordance with
     accounting principles generally accepted in the United States of America.
     All intercompany balances and transactions have been eliminated. In the
     opinion of management, all adjustments (consisting of normal recurring
     adjustments) considered necessary for a fair presentation of the Company's
     financial position, results of operations and cash flows at the dates and
     for the periods indicated have been included. The results of operations for
     the interim periods presented are not necessarily indicative of the results
     for the year ending December 31, 2001. Because all of the disclosures
     required by accounting principles generally accepted in the United States
     of America are not included in the accompanying consolidated financial
     statements and related notes, they should be read in conjunction with the
     audited consolidated financial statements and related notes included in the
     Company's Form 10-K and Form 10-K/A for the fiscal year-ended December 31,
     2000. The year-ended condensed balance sheet data was derived from our
     audited financial statements and does not include all of the disclosures
     required by accounting principles generally accepted in the United States
     of America. The income statements for the periods presented are not
     necessarily indicative of results that we expect for any future period, nor
     for the entire year.

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

2.       Net Income/(Loss) Per Share

     Basic net income/loss per share is computed by dividing net income/loss
     available to common shareholders by the weighted average number of common
     shares outstanding for that period. Diluted net income per share reflects
     the potential dilution from the exercise or conversion of other securities
     into common stock that were outstanding during the period. Diluted net loss
     per share excludes shares that are potentially dilutive as their effect is
     anti-dilutive. Shares that are potentially dilutive consist of incremental
     common shares issuable upon exercise of stock options and warrants.

                                       6


     Basic and diluted income/loss per share are calculated as follows for the
     third quarter and first nine months of 2001 and 2000, respectively:

     The calculation of diluted shares outstanding for the nine months ended
     September 28, 2001 excludes 75,304 stock options, as their effect was
     antidilutive in the period. At September 29, 2000, warrants to purchase
     100,000 shares of the Company's common stock were excluded, because their
     exercise price is greater than the average common stock market price for
     the period.

3.       Inventory:

     Inventory is stated at the lower of standard cost (which approximates cost
     on a first-in, first-out basis) or market value and net of allowances for
     excess and obsolete inventory. Inventory details are as follows (in

4.       Revenue Recognition:

     Product revenue is recognized upon shipment if a signed contract exists,
     the fee is fixed and determinable, collection of the resulting receivables
     is probable and product returns are reasonably estimable. The Company
     enters into agreements with certain of its distributors which permit
     limited stock rotation rights. These stock rotation rights allow the
     distributor to return products for credit but require the purchase of
     additional products of equal value. Revenues subject to stock rotation
     rights are reduced by management's estimates of
                                       7

     anticipated exchanges. Provisions for estimated warranty costs and
     anticipated retroactive price adjustments are recorded at the time products
     are shipped. The Company recognizes revenue from the sale of extended
     warranty contracts ratably over the period of the contracts. In January
     2001, the Company entered into a separate agreement with a Japanese
     distributor to sell the Company's fax server products in Japan. The Company
     is entitled to receive a royalty on sales of products by the distributor.
     Royalty is not recognized as revenue by the Company until the products are
     sold by the distributor.

5.       Segments Disclosure:

     The Company has determined that it operates in one segment. Revenues by
     geographic area are determined by the location of the end user and are

6.       Comprehensive Income:

     Under the Statement of Financial Accounting Standards ("SFAS") No. 130,
     "Reporting Comprehensive Income," disclosure of comprehensive income and
     its components is required in financial statements. Comprehensive income is
     the change in equity from transactions and other events and circumstances
     other than those resulting from investments by owners and distributions to
     owners. There are no significant components of comprehensive income
     excluded from net income, therefore, no separate statement of comprehensive
     income has been presented.

7.       Restructuring:

     In April 2001, the Company terminated 17 regular, temporary and contractor
     positions, which constituted approximately 25% of our workforce. This
     action resulted in a severance charge of $243,000 in the first nine months
     of fiscal 2001. The restructuring included an asset write-off and other
     direct expenses associated with the consolidation of our operations in the
     United Kingdom and El Dorado Hills, California.

     Of the total restructuring charge of $243,000, approximately $213,000
     represented cash charges and the remaining $30,000 represented the
     write-down of assets in the Company's UK operations. The restructuring
     activities were as follows:

                                                                                  Accrued
                                                                              restructuring

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


     The remaining restructuring charges largely relate to additional costs to
     be incurred following the closure of the UK operations as well as the final
     severance payments to certain employees. There was no restructuring charge
     in fiscal 2000.


8.       Commitments and contingencies:

     From time to time, the Company may have certain contingent liabilities that
     arise in the ordinary course of its business activities. The Company
     accrues contingent liabilities when it is probable that future expenditures
     will be made and such expenditures can be reasonably estimated. In the
     opinion of management, there are no pending claims of which the outcome is
     expected to result in a material adverse effect in the financial position
     or results of operations of the Company.

9.       New accounting pronouncements:

     Under SFAS No. 133, "Accounting for Derivative Instruments and Hedging
     Activities," companies are required to recognize all derivatives as either
     assets or liabilities in the statement of financial position and to measure
     those instruments at fair value. Changes in fair value shall be recognized
     currently in earnings. This standard was effective for the Company from
     January 1, 2001. At that time, the Company did not have any derivative
     instruments, nor has it engaged in hedging activities to date.

     In June 2001, the FASB issued Emerging Issues Task Force ("EITF") No.
     00-25, "Vendor Income Statement Characterization of Consideration Paid to
     Reseller of the Vendor's Products," which is effective for annual or
     interim financial statements beginning after December 15, 2001. The issue
     addresses whether consideration paid by a vendor to a reseller for the
     vendor's products is an adjustment of the selling price and should
     therefore be deducted from revenue or a cost incurred by the vendor for
     assets or services received. The Company is currently assessing but has not
     yet determined the impact of EITF 00-25 on its statement of operations.

     In July 2001, the Financial Accounting Standards Board ("FASB") issued SFAS
     No.141, "Business Combinations." SFAS 141 requires the purchase method of
     accounting for business combinations initiated after June 30, 2001 and
     eliminates the pooling-of-interests method. We believe that the adoption of
     SFAS 141 will not have a significant impact on our financial statements.

     In July 2001, the FASB issued SFAS No. 142, "Goodwill and Other Intangible
     Assets," which is effective for fiscal years beginning after March 15,
     2001. SFAS 142 requires, among other things, the discontinuance of goodwill
     amortization. In addition, the standard includes provisions upon adoption
     for the reclassification of certain existing recognized intangibles as
     goodwill, reassessment of the useful lives of existing recognized
     intangibles, reclassification of certain intangibles out of previously
     reported goodwill and the testing for impairment of existing goodwill and
     other intangibles. We believe that the adoption of SFAS 142 will not have a
     significant impact on our financial statements.

                                       9


     In October 2001, the FASB issued SFAS No. 144, "Accounting for the
     Impairment or Disposal of Long-Lived Assets." SFAS 144 supercedes SFAS 121,
     "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
     Assets to Be Disposed Of." SFAS 144 applies to all long-lived assets
     (including discontinued operations) and consequently amends Accounting
     Principles Board Opinion No. 30. SFAS 144 develops one accounting model for
     long-lived assets that are to be disposed of by sale. SFAS 144 requires
     that long-lived assets that are to be disposed of by sale be measured at
     the lower of book value or fair value less cost to sell. Additionally, SFAS
     144 expands the scope of discontinued operations to include all components
     of an entity with operations that (1) can be distinguished from the rest of
     the entity and (2) will be eliminated from the ongoing operations of the
     entity in a disposal transaction. SFAS 144 is effective for the Company for
     all financial statements issued in fiscal 2002. The Company is currently
     assessing but has not yet determined the impact of SFAS 144 on its
     statement of operations.

Results of Operations

     Net Sales

              Net sales for the third quarter of fiscal 2001 were $2.6 million,
     as compared to $3.7 million for the same period in fiscal 2000. The
     shortfall in net sales was primarily due to a reduction in the sales of our
     fax server products of $800,000, or 25%, and the continued decline in the
     sales of the print server products by $371,000, or 73%.

              Net sales were $7.3 million and $11.6 million for the first nine
     months of fiscal 2001 and 2000, respectively. The decrease in net sales
     over the previous year was mostly attributable to the $3.4 million decline,
     or 34%, in demand for our fax server products, and a decrease in the sales
     of our print server products of $920,000, or 58%.

              Domestic sales in the third quarter of fiscal 2001 were $2.1
     million, as compared to $2.9 million in the same period in fiscal 2000,
     representing 83% and 77%, respectively, of total net sales. For the first
     nine months of fiscal 2001, domestic sales were $5.9 million, as compared
     to $8.8 million in the same nine months of fiscal 2000, representing 81%
     and 76%, respectively, of total net sales. The decrease in domestic sales
     in the first nine months of fiscal 2001 was primarily due to lower demand
     for products in the fax server product line.

              International sales in the third quarter of fiscal 2001 were
     $430,000, as compared to $863,000 for the same period in 2000, representing
     17% and 23%, respectively, of total net sales. International sales for the
     first nine months of fiscal 2001 and 2000 were $1.4 million and $2.8
     million, respectively, representing 19% and 24%, respectively, of total net
     sales. This decline in international sales in the first nine months of
     fiscal 2001 was mainly the result of reduced demand for our fax server
     product line of $478,000, or 30%, and our print server products of
     $904,000, or 75%.

     Cost of Sales; Gross Profit

              Gross profit of $1.8 million, or 70% of net sales, for the third
     quarter of fiscal 2001, decreased, as compared to gross profit of $2.4
     million, or 65%, for the same period in fiscal 2000. The higher gross
     profit percentage in the third quarter of fiscal 2001 was largely due to
     the increasingly favorable mix from the sales of our fax server products,
     which has a higher gross profit contribution, as compared to the sales of
     our print server products, which yields a lower gross margin.

              Gross profits for the first nine months of fiscal 2001 and 2000
     were $5 million, or 68% of net sales and $7.3 million, or 63% of net sales,
     respectively. The increase in gross profit percentage for the nine months
     of fiscal 2001 was primarily due to the mix of products that were sold at a
     higher average selling price. The change in the first quarter of fiscal
     2001 from directly selling our print server products to our distributor in
     Japan to a royalty collection model also contributed to the higher gross
     profit, even though the amount of royalties received was not significant.

     Research & Development

              Research and product development expenses were $470,000, or 18%,
     of net sales for the third quarter of fiscal 2001, as compared to $441,000,
     or 12%, of net sales for the same period in fiscal 2000. Research and
     product development expenses for the first nine months of 2001 were $1.3
     million, or 18% of net sales, as compared to $1.4 million, or 12% of net
     sales, for the same period in fiscal 2000. This reduction of $99,000 in the
     nine-month period was mostly due to lower compensation expenses.


                                       12


     Sales & Marketing

              Sales and marketing expenses were $919,000 or 36%, of net sales
     for the third quarter of fiscal 2001, as compared to $1.4 million, or 37%
     of net sales for the same period in fiscal 2000. The reduction of $449,000
     was mostly attributable to lower operating expenses of $107,000 in our
     United Kingdom operation as a result of our consolidation efforts earlier
     in the year, lower compensation and consulting expenses of $136,000, and
     decreased promotional expenses of $127,000. For the first nine months of
     fiscal 2001, sales and marketing expenses were $3.1 million, or 42% of net
     sales, as compared to $4 million, or 35% of net sales, for the same period
     in fiscal 2000. This reduction of sales and marketing spending by $928,000
     was mostly attributable to lower operating expenses of $107,000 in the
     United Kingdom, lower compensation and consulting expenses of $260,000,
     decreased promotional expenses of $260,000 and a reduction in other general
     expenses of $217,000.

     General & Administrative

              General and Administrative expenses were $353,000 and $383,000, or
     14% and 10%, respectively, of net sales for the third quarter of fiscal
     2001 and 2000, respectively. General and administrative expenses for the
     first nine months of fiscal 2001 decreased to $1.1 million, or 14% of net
     sales, as compared to $1.3 million, or 11%, of net sales for the same
     period in fiscal 2000. The reduction in general and administration expenses
     of $213,000 was primarily due to lower legal and consulting expenses of
     $77,000, decreased recruiting expenses of $45,000 and lower bad debt and
     collection expenses of $76,000.

     Restructuring

     In April 2001, we terminated 17 regular, temporary and contractor
     positions, which constituted approximately 25% of our workforce. This
     action resulted in a restructuring charge of $243,000 in the nine months of
     fiscal 2001. The restructuring included an asset write-off and other direct
     expenses associated with the consolidation of our operations in the United
     Kingdom and El Dorado Hills, California. There was no restructuring charge
     in fiscal 2000.


Liquidity and Capital Resources

         As of September 28, 2001, we had approximately $4.1 million of cash and
cash equivalents as compared to $3.9 million at December 31, 2000. Working
capital improved slightly to $3.5 million at September 28, 2001 from $3.3
million at June 29, 2001, but decreased from $4 million at December 31, 2000.
The improvement in cash and cash equivalents from the second quarter of fiscal
2001 was mostly attributable to improved collection of outstanding balances owed
to us by our customers, reduced inventory to meet the current revenue
projections, offset in part by more timely payments to our vendors. The
reduction in working capital, compared to December 31, 2000, was primarily due
to the fiscal 2001 year to date net loss, partially offset by improved
collections from customers and reduced inventory.

         The restricted cash of $125,000 appearing on our balance sheet as of
December 31, 2000, was a certificate of deposit to collateralize a loan and was
returned to us in February 2001. The loan was completely paid off as of December
31, 2000.

         We have a $3 million secured revolving line of credit with a bank from
which we may borrow 100% against pledges of cash at the bank's prime rate. As of
September 28, 2001, we had no borrowings under this line of credit.

         In December 2000, as a source of capital asset financing, we entered
into a loan and security agreement with a finance company for an amount of
$75,000. This loan is subject to

                                       13


interest of 12.8% and is repayable by December 2006. As of September 28, 2001,
the future minimum payments were $90,000.

         In April 2001, we entered into a loan and security agreement with a
finance company for an amount of $25,000. This loan is subject to interest of
12.5% and is repayable by April 2003. As of September 28, 2001, the future
minimum payments were $25,000.

         As of September 28, 2001, net accounts receivable were $666,000, down
from $2.1 million at December 31, 2000. The September 28, 2001 balance was net
of allowances for doubtful accounts, estimated product returns and price
protection of $760,000, which is in compliance with our revenue recognition
policies, as compared to allowances of $667,000 at December 31, 2000. The
decrease in net accounts receivable was largely attributed to improved
collection of outstanding balances and reduced sales in the nine months of this
year.

         Net inventory as of September 28, 2001 was $1.3 million, compared to
$1.4 million at December 31, 2000 and $1.6 million as of June 29, 2001. The
planned inventory reductions were in line with current revenue projections.
Inventory turnover reduced from an equivalent of 3.5 turns per year at December
31, 2000 to 2.4 turns per year in this current quarter.

         Although we believe that our existing capital resources, anticipated
cash flows from operations and available lines of credit will be sufficient to
meet our capital requirements for at least the next 12 months, we may be
required to seek additional equity or debt financing. The timing and amount of
such capital requirements cannot be determined at this time and will depend on a
number of factors, including demand for our existing and new products and the
pace of technological change in the networking industry. There can be no
assurance that such additional financing will be available on satisfactory terms
when needed, if at all. In order to maximize shareholder value, the Board of
Directors continues to evaluate various strategic alternatives that may be
available to us.

         We believe that, for the periods presented, inflation has not had a
material effect on our operations.

                           PART II - OTHER INFORMATION

Item 1.    Legal Proceedings

           None.

Item 2.    Changes in Securities and Use of Proceeds

           None.

Item 3.    Quantitative and Qualitative Disclosure About Market Risk

           We considered the provision of Financial Reporting Release No. 48
"Disclosure of Accounting Policies for Derivative Financial Instruments and
Derivative Commodity Instruments, and Disclosure of Quantitative and Qualitative
Information about Market Risk Inherent in Derivative Financial Instruments,
Other Financial Instruments and Derivative Commodity Instruments." We had no
holdings of derivative financial or commodity instruments at September 28, 2001.
However, we are exposed to financial market risks, including changes in interest
rates and foreign currency exchange rates. While much of our revenue is
transacted in U.S dollars, some revenues and capital spending are transacted in
Pounds Sterling. These amounts are not currently material to our financial
statements; therefore we believe that foreign currency exchange rates should not
materially affect our overall financial position, results of operations or cash
flows. The fair value of our money market account or related income would not be
significantly impacted by increases or decreases in interest rates due mainly to
the highly liquid nature of this investment. However, sharp declines in interest
rates could seriously harm interest earnings on this account.


Item 4.    Submission of Matters to a Vote of Security Holders

           None.

Item 5.    Other Information

           In April 2001, we terminated 17 regular, temporary and contractor
positions, which constituted approximately 25% of our workforce. This action
resulted in a restructuring charge of $243,000 in the nine months of fiscal
2001. The restructuring included an asset write-off and other direct expenses
associated with the consolidation of our operations in the United Kingdom and El
Dorado Hills, California. There was no restructuring charge in fiscal 2000.
