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

                            CASTELLE AND SUBSIDIARIES
              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
     accruals)  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 result of operations for
     the interim period  presented is 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  earnings  per share are  calculated  as follows for the
     second quarter and first six months of 2001 and 2000, respectively:

     The  calculation of diluted shares  outstanding  for the three months ended
     June  29,  2001  excludes  options  to  purchase  1,327,089  shares  of the
     Company's common stock, as their effect was antidilutive in the period. The
     calculation of diluted shares outstanding for the six months ended June 29,
     2001, excludes options to purchase 1,319,089 shares of the Company's common
     stock, as their effect was  antidilutive  in the period.  At June 30, 2000,
     warrants to purchase  100,000  shares of the  Company's  common  stock were
     excluded,  because the per share exercise price of each of the warrants was
     greater than the average  market price for a share of the Company's  common
     stock for the period.

3.   Inventories:

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

4.   Revenue Recognition:
     --------------------

     Product revenue is recognized  upon shipment if a signed  contract  exists,
     the fee is fixed or 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  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


                                       7


     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.   Segmental Disclosure and Geographic Information:
     -------------------------------------------------

     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
     summarized as follows (in thousands):

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 its  workforce.  This
     action  resulted in a severance  charge of $58,000 in the second quarter of
     fiscal  2001.  This  severance  charge is in addition to the  restructuring
     charge of $180,000  recorded  in the first  quarter of fiscal  2001,  which
     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.

8.   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 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.

                                       8


     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.

     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 from a vendor to a reseller of 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  Compnay is  currently  assessing  but has not yet
     determined the impact of EITF 00-25 on its statement of operations.

     Results of Operations


     Net Sales

          Net sales for the second quarter of fiscal 2001 were $2.4 million,  as
     compared  to $3.8  million  for the same  period in fiscal  2000.  The $1.4
     million  decrease was largely due to a shortfall  in the domestic  sales of
     our fax server products.

          Net sales for first the six months were $4.7  million and $7.9 million
     for  fiscal  2001 and  2000,  respectively.  The  shortfall  in  sales  was
     primarily  due to the $2.6 million  decline,  or 38%, in demand for our fax
     server  products,  and a decrease in the sales of our print server products
     of $549,000, or 50%.

          Domestic sales in the second quarter of fiscal 2001 were $1.9 million,
     as compared to $3 million in the same period in fiscal 2000.  For the first
     six months of fiscal 2001, domestic sales were $3.8 million, as compared to
     $5.9 million, a decrease of 37%, mostly in our fax server product line.

          International  sales in the second quarter of fiscal 2001 decreased to
     $517,000 from $755,000 for the same period in fiscal 2000, representing 22%
     and 20%,  respectively,  of total net  sales.  International  sales for the
     first six months of fiscal 2001 and 2000 were  $968,000  and $1.9  million,
     representing 21% and 24%, respectively, of total net sales. This decline in
     international  sales was mainly the result of reduced  demand for our print
     server products in the Asia Pacific Region and the change made earlier this
     year from a model of selling  our print  server  products  directly  to our
     distributor in Japan to a royalty  collection  model.  The royalty  amounts
     received by us in the first six months of this year were not significant.

     Cost of Sales; Gross Profit

          Gross  profit of $1.5  million,  or 64% of net  sales,  for the second
     quarter of fiscal 2001  decreased,  as compared to $2.5 million,  or 65% of
     net sales for the same period in fiscal 2000.  The gross profit  percentage
     in the second  quarter of fiscal 2001 was  comparable to the second quarter
     of fiscal 2000.

          Gross  profits  for the first six months of fiscal  2001 and 2000 were
     $3.2 million,  or 67% of net sales and $4.9  million,  or 62% of net sales,
     respectively.  The  increase  in gross  profit for the six 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 to a
     royalty collection model from directly selling our print server products to
     our distributor in Japan 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 $481,000, or 20% of net
     sales for the second  quarter of fiscal 2001,  as compared to $489,000,  or
     13% of net sales for the same period in fiscal  2000.  Research and product
     development expenses for the first six months were $866,000,  or 18% of net
     sales in fiscal 2001, as compared to $994,000,  or 13% of net sales for the
     same period in fiscal 2000.  This  reduction  of $128,000 in the  six-month
     period was mostly due to lower compensation expenses.  Research and product
     development  spending  in the  second  quarter  of  fiscal  2001,  however,
     increased  sequentially  by  $96,000,  primarily  due  to  higher  external
     consulting and compensation expenses.

                                       11




     Sales & Marketing

          Sales and marketing expenses were $1 million,  or 44% of net sales for
     the second  quarter of fiscal 2001, as compared to $1.3 million,  or 35% of
     net sales for the same period in fiscal 2000. The reduction of $293,000 was
     mostly  contributable  to lower  promotional  expenses of  $101,000,  lower
     consulting of $29,000 and a decrease in other general expenses of $133,000.
     For the first six months of fiscal 2001, the expenses were $2.2 million, or
     46% of net sales, as compared to $2.6 million,  or 34% of net sales for the
     same period in fiscal 2000. This reduction of sales and marketing  spending
     by  $479,000  was mostly  attributable  to lower  promotional  expenses  of
     $103,000, lower compensation of $65,000 and a decrease in other expenses of
     $230,000.

     General & Administrative

          General and administrative expenses were $255,000, or 11% of net sales
     for the second  quarter of fiscal 2001, as compared to $416,000,  or 11% of
     net sales for the same period in fiscal 2000.  The reduction of $161,000 in
     the second quarter in fiscal 2001 was  principally due to a lower provision
     for doubtful accounts of $73,000 and lower legal and consulting expenses of
     $47,000.  General and  administrative  expenses for the first six months of
     fiscal 2001 were $699,000,  or 15% of net sales in fiscal 2001, as compared
     to $882,000,  or 11% of net sales for the same period in fiscal  2000.  The
     reduction in general and administration  expenses of $183,000 was primarily
     due to lower  legal  and  consulting  expenses  of  $97,000  and a  $59,000
     decrease in other general administrative expenses.
     Restructuring

          In April 2001,  we terminated  17 regular,  temporary  and  contractor
     positions,  which  constituted  approximately  25% of our  workforce.  This
     action  resulted in a severance  charge of $58,000 in the second quarter of
     fiscal  2001.  This  severance  charge is in addition to the  restructuring
     charge of $180,000  recorded  in the first  quarter of fiscal  2001,  which
     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 June 29,  2001,  we had  approximately  $3.6 million of cash and cash
equivalents,  as compared to $3.9 million at December 31, 2000.  The decrease in
cash and cash  equivalents of $293,000 was primarily due to the overall  decline
in sales,  the severance charge in April 2001 and the net loss for the first six
months of fiscal 2001.

     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
June 29, 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 interest of 12.8% and is repayable by December  2006. As
of June 29, 2001, the future minimum payments were $94,000.

                                       12


     In April 2001,  as a source of capital asset  financing,  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 2004.  As of
June 29, 2001, the future minimum payments were $30,000.

     As of June 29, 2001, net accounts  receivable were $1.2 million,  down from
$2.1 million at December 31, 2000.  The decrease in net accounts  receivable was
largely  attributable to improved collection of outstanding balances and reduced
sales in the first  six  months of  fiscal  2001.  The  number of days for which
payment for sales is  outstanding  improved from 58 days at December 31, 2000 to
45 days at June 29, 2001.

     Net  inventory as of June 29, 2001 was $1.6  million,  an increase from the
$1.4 million at December 31, 2000. The higher  inventory level was partly due to
a planned increase for a small build-up of our best selling fax server models to
ensure quick  turn-around  to our  customers.  The slower than expected sales in
some  other fax  server  products  also  contributed  to the  overall  increase.
Inventory  turnover  improved  from an  equivalent  of 1.9 turns per year in the
first quarter of fiscal 2001 to 2.1 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
contunues 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.

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 June 29, 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.
