1.  INTERIM PERIOD ACCOUNTING POLICIES

In the opinion of the Company's management, the accompanying unaudited
condensed consolidated financial statements contain all normal recurring
adjustments necessary to present fairly the financial position as of September
30, 1995, and consolidated results of operations for the three and nine months
ended September 30, 1995, and September 30, 1994, and cash flows for the nine
month periods ended September 30, 1995, and September 30, 1994.  Results of
operations for the three and nine months ended September 30, 1995, are not
necessarily indicative of results to be expected for the full year ending
December 31, 1995.

Although the Company believes that the disclosures in the financial statements
are adequate to make the information presented not misleading, certain
information and footnote information normally included in financial statements
prepared in accordance with generally accepted accounting principles have been
condensed or omitted pursuant to the rules and regulations of the Securities
and Exchange Commission.  Accordingly, these financial statements should be
read in  conjunction with the Company's audited consolidated financial
statements included in the Company's Form 10-K/A for the year ended December
31, 1994.

Certain prior year amounts have been reclassified to conform with the current
period's presentation.

2.  PRINCIPLES OF CONSOLIDATION

5.  NOTES PAYABLE TO BANK

The Company maintains an unsecured line of credit with a bank.  The line allows
maximum borrowings of $10,000,000, of which up to $2,000,000 may be utilized
for the secured purchase of fixed assets (term loan), $2,000,000 for letters of
credit and $2,000,000 for foreign exchange contracts.  The line bears interest
at the prime rate (8.75% at September 30, 1995) and borrowings under term loan
provisions of the agreement bear interest at prime plus 1%.  At September 30,
1995, the Company had no outstanding borrowings under this line of credit.

                                PART I:  ITEM 2

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

                          PAIRGAIN TECHNOLOGIES, INC.


RESULTS OF OPERATIONS (quarter and nine months ended September 30, 1995,
compared to quarter and nine months ended September 30, 1994)

REVENUES

Revenues for the quarter ended September 30, 1995, were $29.6 million, an
increase of $14.4 million or 94% compared to the third quarter of 1994.
Revenues for the 1995 nine month period were $72.6 million, an increase of 75%
compared to revenues of $41.4 million in the prior year period.  Of these
increases in revenues, product revenues increased $14.5 million in the 1995
quarter compared to the 1994 quarter, and $31.8 million in the nine month
period.  These increases were offset by decreases in royalty income of $88,000
and $569,000, respectively, for the quarter and nine month periods.  The
increase in product revenues was due primarily to increases in unit sales
volume of the Company's HiGain, PG-2, and Campus products.  These increases
were marginally offset by a decline in the average selling prices due to
competitive pressures.  The decrease in royalty income was due to a reduction
of fees generated by licenses for the use of the Company's HDSL technology.

GROSS PROFIT

Gross profit increased $6.9 million or 102%  to $13.8 million in the quarter
ended September 30, 1995.  Gross Profit for the nine month period was $34.6
million compared to $18.2 million in the prior year period.  Gross profit as a
percentage of revenues was 47% for the quarter ended September 30, 1995
compared to 45% in the 1994 quarter.  For the nine months ended September 30,
1995 gross profit as a percentage of revenues was 48% compared to 44% in the
1994 period.  These improvements in gross profit percentage are attributable to
the Company's continuing engineering design changes, reduced prices for
components, increased manufacturing efficiencies, and increases in volume.  For
the 1995 reporting periods, cost reductions more than offset declines in
average selling prices, as compared with the 1994 periods.

The Company expects that increased competition will continue to place downward
pressure on the average sales prices of its existing products.  Declining
average sales prices may adversely affect gross product margins on the
Company's existing products if the Company is unable to fully offset such price
reductions by reductions in the Company's per unit cost.  The Company's ability
to mitigate future declines in its gross product margin will depend in part
upon its ability to introduce and sell new products with higher gross product
margins and further reduce its per unit costs.

RESEARCH AND DEVELOPMENT

Research and development expenses increased to $2.8 million in the quarter
ended September 30, 1995, compared to $1.5 million in the prior year period.
Research and development expenses were $7.6 million compared to $4.0 million
for the nine months ended September 30, 1995, and 1994, respectively.  The 1995
increases in expenses were primarily due to the addition of personnel,
depreciation on additional capital equipment, prototype expenditures and
payments to outside consultants.  As a percentage of revenues, research and
development expenses were approximately 10% during the quarter and nine month
periods ended September 30, 1995 and 1994.

SALES AND MARKETING

Sales and marketing expenses increased $1.4 million or 104% to $2.7 million and
increased $3.0 million or 77% to $6.8 million, respectively, for the quarter
and nine months ended September 30, 1995, as compared with the same periods in
the prior year.  The 1995 increases were primarily due to the addition of sales
and marketing support personnel, commissions related to higher revenue levels,
and increased advertising and travel.  As a percentage of revenues, sales and
marketing expenses were approximately 9% during the quarter and nine month
periods ended September 30, 1995 and 1994.

GENERAL AND ADMINISTRATIVE

General and administrative expenses increased $0.6 million or 51% and $1.7
million or 54%, respectively, for the quarter and nine months ended September
30, 1995, as compared with the 1994 periods. These increases were primarily due
to the addition of personnel, payments to outside consultants related to the
implementation of an information systems upgrade, and additional bad debt
provisions.  As a percentage of revenues, general and administrative expenses
decreased to 6% and 7%, respectively, for the quarter and nine months ended
September 30, 1995 compared to 8% for the quarter and nine months ended
September 30, 1994.

INTEREST AND OTHER INCOME, NET

Interest and other income includes net interest income and net gain or loss on
sales of investments. Interest and other income decreased $145,000 and $40,000,
respectively, for the quarter and nine months ended September 30, 1995, as
compared with the same periods in the prior year, largely due to lower net
gains on sales of investments in the current year periods.





                                       10

PROVISION FOR INCOME TAXES

The provision for income taxes increased $1.2 million and $2.6 million,
respectively, for the quarter and nine months ended September 30, 1995, as
compared with the same periods in the prior year due to large increases in
pre-tax income.


NET INCOME

As a result of the foregoing, the Company's net income increased $2.3 million
to $4.5 million for the quarter ended September 30, 1995.  Net income for the
nine months ended September 30, 1995 was $11.3 million, an increase of 100%
compared to the prior year's income of $5.6 million.  Earnings per share for
the quarter ended September 30, 1995 were $0.26 compared to $0.15 in the 1994
quarter.  Earnings per share for the nine months ended September 30, 1995 were
$0.68 compared to $0.37 for the nine months ended September 30, 1994.  The
weighted average number of common and common equivalent shares outstanding were
17.1 million and 15.3 million for the quarters ended September 30, 1995 and
1994, respectively.  The weighted average number of common and common
equivalent shares for the nine months ended September 30, 1995 and 1994, were
16.6 million and 15.4 million, respectively.  These increases in common and
common equivalent shares are primarily attributed to the issuance of 500,000
shares in the Company's secondary offering in March 1995, the granting of
options to key employees of the Company, and the reduction in the number of
shares assumed to be repurchased upon the exercise of options and warrants,
using the treasury stock method, as a result of the Company's higher stock
price in 1995 over 1994.





                                       11

LIQUIDITY AND CAPITAL RESOURCES

As of September 30, 1995, the Company had $68.8 million in cash, cash
equivalents and short-term investments and $93.2 million in working capital.
These figures represent an increase of $15.6 million in cash, cash equivalents
and short-term investments and $21.9 million in working capital over the
December 31, 1994 amounts.  These increases are primarily due to the receipt of
$13.2 million in cash from the Company's secondary stock offering that took
place in March 1995.  Although accounts receivable collection days at September
30, 1995, decreased to 35 days compared to 53 days at December 31, 1994, the
Company's accounts receivable balance increased to $11.5 million from $10.2
million at the end of 1994 as a result of increased sales levels during the
third quarter of 1995.  Inventory increased to $21.4 million at September 30,
1995, compared to $16.5 million at December 31, 1994, due to higher shipment
levels.  However, inventory turns increased to 3.0 at the end of the third
quarter, compared to 2.4 at the end of 1994.

Capital expenditures during the nine month period ended September 30, 1995 were
$4.8 million compared to $1.3 million for the comparable period in 1994.  The
increase in capital spending was primarily due to tenant improvements at the
Company's Tustin facility totaling $849,000 and the purchase of computer
equipment, test equipment and software.  The Company  has entered into an
agreement to purchase software and equipment to upgrade its information system
capabilities.  The total commitment thereunder is approximately $750,000, of
which $561,000 has been invested as of September 30, 1995.

In May 1995, the Company amended the Loan and Security Agreement with its bank
which provides for a revolving unsecured credit facility of $10 million,
subject to sublimits for amounts utilized for term loans, letters of credit and
foreign exchange contracts.  The Loan Agreement contains operating covenants,
including limitations on the ability to take certain corporate actions.  The
Loan Agreement also requires the Company to be in compliance with certain
financial ratios.  At September 30, 1995 the Company had no outstanding
borrowings under the Loan Agreement and was in compliance with all financial
and operating covenants.  The amended Loan Agreement expires May 1, 1996.

On July 20, 1995, the Company entered into certain agreements with Source-Comm
Corporation of Valencia, California ("Source-Comm").  Source- Comm is a
cost/performance leader in remote networking devices which enable the
integration of Ethernet local area networks with wide area networking over
copper wire.  The agreements provide for the incorporation of Source-Comm's
networking technology into the Company's current and future transmission
products.  Under the terms of the agreements, the Company will lend Source-Comm
$2.7 million and has rights to obtain a minority ownership position.  During
the third quarter, the Company advanced $1.4 million to Source-Comm.  The
remainder is to be funded during the fourth quarter of 1995.

The Company has no other material near-term commitments for its funds, which
are currently held in investment grade, interest-bearing securities.  The
Company believes that cash generated from operations will be sufficient to fund
anticipated operating expenses for the foreseeable future, although cash
requirements in certain quarters may exceed internally-generated funds.

Item 5.  Other Information
         Mr. Brian Kouri, a director of the Company since August 1992,
         resigned effective September 15, 1995.  There were no disagreements
         between Mr. Kouri and the Company.  Mr. Kouri's decision to resign was
         based solely upon the fact that during the third quarter of 1995, BCE
         Venture Capital, Inc., of which Mr. Kouri is an executive officer,
         disposed of the majority of its shares in the Company.  As a result,
         BCE is no longer a significant stockholder in the Company. 
         Accordingly, Mr. Kouri decided to focus his attention on BCE's other
         investments and businesses.

                          PAIRGAIN TECHNOLOGIES, INC.

                         COMMON STOCK PURCHASE WARRANT


                 THIS CERTIFIES THAT, for value received, BROBECK, PHLEGER &
HARRISON (the "Holder") is entitled, upon the terms and subject to the
conditions hereinafter set forth, at any time or from time to time, prior to
5:00 p.m. Pacific Time on May 10, 1998, to subscribe for and purchase from
PairGain Technologies, Inc., a California corporation (the "Company"), Five
Thousand (5,000) fully paid and non-assessable shares of the Common Stock of
the Company for the aggregate exercise price of One Hundred Thousand and No/100
Dollars ($100,000).  Hereinafter, (i) the Common Stock of the Company, together
with any other equity securities which may be issued by the Company in
substitution therefor, is referred to as the "Common Stock," (ii) the shares of
the Common Stock purchasable hereunder are referred to as the "Warrant Shares,"
(iii) the aggregate exercise price payable for all of the Warrant Shares is
referred to as the "Aggregate Exercise Price," and (iv) the price payable
hereunder for each of the Warrant Shares is referred to as the "Per Share
Exercise Price," which shall initially be Twenty and No/100 Dollars ($20.00)
per share.  The Per Share Exercise Price and the number of Warrant Shares are
subject to adjustment as hereinafter provided.

         1.      Exercisability.

                 1.1      Exercise of Warrant.  This Warrant may be exercised,
in whole at any time or in part from time to time, prior to 5:00 p.m. Pacific
Time on May 10, 1998 (subject to earlier termination as hereinafter provided),
by the Holder (the "Holder") by the surrender of this Warrant (with the
subscription form at the end hereof duly executed) at the principal office of
the Company, which is currently located at 14402 Franklin Avenue, Tustin,
California 92680, together with proper payment of the Per Share Exercise Price
for each of the Warrant Shares as to which the Warrant is being exercised.
Payment for Warrant Shares shall be made by certified or bank cashier's check,
payable to the order of the Company.

<PAGE>   2
                 If this Warrant is exercised in part, this Warrant must be
exercised for a number of whole shares of the Common Stock and the Holder shall
be entitled to receive a new Warrant covering the number of Warrant Shares with
respect to which this Warrant has not been exercised.  Upon such surrender of
this Warrant, together with the subscription form at the end hereof duly
executed and proper payment of the Per Share Exercise Price for each of the
Warrant Shares as to which the Warrant is being exercised, the Company will (i)
issue, or cause the Company's transfer agent to issue, a certificate or
certificates in the name of the Holder for the largest number of whole shares
of the Common Stock to which the Holder shall be entitled and, if this Warrant
is exercised in whole, in lieu of any fractional share of the Common Stock to
which the Holder shall be entitled, cash equal to the fair value of such
fractional share (as determined by the last reported selling price of the
Common Stock on the last business day before the date the Warrant is
exercised), and (ii) deliver the other securities and properties receivable
upon the exercise of this Warrant, if any, or the proportionate part thereof if
this Warrant is exercised in part, pursuant to the provisions of this Warrant.

                 1.2      Net Issue Election.  The Holder may elect to receive,
without the payment by the Holder of any additional consideration, shares equal
to the value of this Warrant or any portion hereof by the surrender of this
Warrant or such portion to the Company, with the net issue election notice
annexed hereto duly executed, at the office of the Company.  Thereupon, the
Company shall issue to the Holder such number of fully paid and nonassessable
shares of Common Stock as is computed using the following formula:

                                  X = Y (A-B)
                                      ------- 
                                         A
where:

         X =     the number of shares to be issued to the Holder pursuant to
                 this Section 1.2.

         Y =     the number of shares covered by this Warrant in respect of
                 which the net issue election is made pursuant to this Section 
                 1.2.

         A =     the fair market value of one share of Common Stock, as
                 determined in accordance with the provisions of this Section 
                 1.2.

         B =     the Per Share Exercise Price in effect under this Warrant at
                 the time the net issue election is made pursuant to this
                 Section 1.2.

For purposes of this Section 1.2, the "fair market value" per share of the
Company's Common Stock shall mean the last reported sale price of the Common
Stock on the last business day before the effective date of exercise of the net
issue election.

         2.      Reservation of Warrant Shares.  The Company agrees that, prior
to the expiration of this Warrant, the Company will at all times have
authorized and in reserve, and will keep available, solely for issuance or
delivery upon the exercise of this Warrant, the shares of the Common Stock and
other securities and properties as from time to time shall be receivable upon
the exercise of this Warrant.

         3.      Adjustments.

                 3.1      Distribution With Respect to Common Stock.  If, at
any time or from time to time after the date of this Warrant, the Company shall
distribute to the holders of the Common Stock, without payment therefor, (i)
securities, other than shares of the Common Stock, or (ii) property, other than
cash, with respect to the Common Stock, then, and in each such case, subject to
Section 3.4 below, the Holder, upon the exercise of this Warrant, shall be
entitled to receive the securities and properties which the Holder would hold
on the date of such exercise if, on the date of such distribution, the Holder
had been the holder of record of the number of shares of the Common Stock
subscribed for upon such exercise and, during the period from the date of such
distribution to and including the date of such exercise, had retained such
shares and the securities and properties receivable by the Holder during such
period.

                 3.2      Stock Splits, Etc.  If, at any time or from time to
time after the date of this Warrant, the Company shall issue to the holders of
the Common Stock shares of the Common Stock by way of a stock dividend or stock
split, then, and in each such case, the Per Share Exercise Price shall be
adjusted, or further adjusted, to a price (to the nearest whole cent)
determined by dividing (1) an amount equal to the number of shares of the
Common Stock outstanding immediately prior to such issuance multiplied by the
Per Share Exercise Price as it existed immediately prior to such issuance by
(ii) the total number of shares of the Common Stock outstanding immediately
after such issuance.  Upon each such adjustment in the Per Share Exercise
Price, the number of Warrant Shares shall be adjusted by dividing the Aggregate
Exercise Price by the Per Share Exercise Price in effect immediately after such
adjustment.

                 3.3      Reverse Splits, Etc.  If, at any time or from time to
time after the date of this Warrant, the number of shares of Common Stock
outstanding is decreased by way of combination of shares or reserve split,
then, and in each such case, the Per Share Exercise Price shall be adjusted, or
further adjusted, to a price (to the nearest whole cent) determined by dividing
(i) an amount equal to the number of shares of the Common Stock outstanding
immediately prior to such event multiplied by the Per Share Exercise Price as
it existed immediately prior to such event by (ii) the total number of shares
of the Common Stock outstanding immediately after such event.  Upon each such
adjustment in the Per Share Exercise Price, the number of Warrant Shares shall
be adjusted by dividing the Aggregate Exercise Price by the Per Share Exercise
Price in effect immediately after such adjustment.

                 3.4.     Adjustment for Reorganization, Consolidation, Merger,
                          etc.

                          a.      Reorganization, Consolidation, Merger, etc.
In case at any time or from time to time, the Company shall (i) effect a
reorganization, (ii) consolidate with or merge into any other entity or person,
or (iii) transfer all or substantially all of its properties or assets to any
other entity or person under any plan or arrangement contemplating the
dissolution of the Company, then, in each such case, the Holder, on the
exercise hereof as provided in Section 1 at any time after the consummation of
such reorganization, consolidation or merger or the effective date of such
reorganization, consolidation or merger, as the case may be, shall receive, in
lieu of the Common Stock (or other securities) issuable on such exercise prior
to such consummation or such effective date, the stock and other securities and
property (including cash) to which the Holder would have been entitled upon
such consummation or in connection with such dissolution, as the case may be,
if the Holder had so exercised this Warrant, immediately prior thereto, all
subject to further adjustment thereafter as provided in this Section 3.

                          b.      Dissolution.  In the event of any dissolution
of the Company following the transfer of all or substantially all of its
properties or assets, the Company, prior to such dissolution, shall at its
expense deliver or cause to be delivered the stock and other securities and
property (including cash, where applicable) receivable by the Holder after the
effective date of such dissolution pursuant to this Section 3.4 to a bank or
trust company having its principal office in Orange County, California, as
trustee for the Holder.

                          c.      Continuation of Terms.  Upon any
reorganization, consolidation, merger or transfer (and any dissolution
following any transfer) referred to in this Section 3.4, this Warrant shall
continue in full force and effect, subject to expiration in accordance with
Section 1 hereof, and the terms hereof shall be applicable to the shares of
stock and other securities and property receivable on the exercise of this
Warrant after the consummation of such reorganization, consolidation or merger
or the effective date of dissolution following any such transfer, as the case
may be, and shall be binding upon the issuer of any such stock or other
securities, including, in the case of any such transfer, the entity or person
acquiring all or substantially all of the properties or assets of the Company,
whether or not such entity or person shall have expressly assumed the terms of

Date of Issuance:  August 3, 1995


                          PAIRGAIN TECHNOLOGIES, INC.

                         COMMON STOCK PURCHASE WARRANT


                 THIS CERTIFIES THAT, for value received, NEXUS APPLIED
RESEARCH, INC. (the "Holder") is entitled, upon the terms and subject to the
conditions hereinafter set forth, at any time or from time to time, prior to
5:00 p.m. Pacific Time on September 1, 1999, to subscribe for and purchase from
PairGain Technologies, Inc., a California corporation (the "Company"), Five
Thousand (5,000) fully paid and non- assessable shares of the Common Stock of
the Company for the aggregate exercise price of One Hundred Twenty-five
Thousand Dollars ($125,000).  Hereinafter, (i) the Common Stock of the Company,
together with any other equity securities which may be issued by the Company in
substitution therefor, is referred to as the "Common Stock," (ii) the shares of
the Common Stock purchasable hereunder are referred to as the "Warrant Shares,"
(iii) the aggregate exercise price payable for all of the Warrant Shares is
referred to as the "Aggregate Exercise Price," and (iv) the price payable
hereunder for each of the Warrant Shares is referred to as the "Per Share
Exercise Price," which shall initially be Twenty- five Dollars ($25.00) per
share.  The Per Share Exercise Price and the number of Warrant Shares are
subject to adjustment as hereinafter provided.

         1.      Exercisability.

                 1.1      Exercise of Warrant.  This Warrant may be exercised,
in whole at any time or in part from time to time, prior to 5:00 p.m. Pacific
Time on September 1, 1999 (subject to earlier termination as hereinafter
provided), by the Holder (the "Holder") by the surrender of this Warrant (with
the subscription form at the end hereof duly executed) at the principal office
of the Company, which is currently located at 14402 Franklin Avenue, Tustin,
California 92680, together with proper payment of the Per Share Exercise Price
for each of the Warrant Shares as to which the Warrant is being exercised.
Payment for Warrant Shares shall be made by certified or bank cashier's check,
payable to the order of the Company.





<PAGE>   2
                 If this Warrant is exercised in part, this Warrant must be
exercised for a number of whole shares of the Common Stock and the Holder shall
be entitled to receive a new Warrant covering the number of Warrant Shares with
respect to which this Warrant has not been exercised.  Upon such surrender of
this Warrant, together with the subscription form at the end hereof duly
executed and proper payment of the Per Share Exercise Price for each of the
Warrant Shares as to which the Warrant is being exercised, the Company will (i)
issue, or cause the Company's transfer agent to issue, a certificate or
certificates in the name of the Holder for the largest number of whole shares
of the Common Stock to which the Holder shall be entitled and, if this Warrant
is exercised in whole, in lieu of any fractional share of the Common Stock to
which the Holder shall be entitled, cash equal to the fair value of such
fractional share (as determined by the last reported selling price of the
Common Stock on the last business day before the date the Warrant is
exercised), and (ii) deliver the other securities and properties receivable
upon the exercise of this Warrant, if any, or the proportionate part thereof if
this Warrant is exercised in part, pursuant to the provisions of this Warrant.

                 1.2      Net Issue Election.  The Holder may elect to receive,
without the payment by the Holder of any additional consideration, shares equal
to the value of this Warrant or any portion hereof by the surrender of this
Warrant or such portion to the Company, with the net issue election notice
annexed hereto duly executed, at the office of the Company.  Thereupon, the
Company shall issue to the Holder such number of fully paid and nonassessable
shares of Common Stock as is computed using the following formula:

                                  X = Y (A-B)
                                      -------   
                                         A
where:

         X =     the number of shares to be issued to the Holder pursuant to 
                 this Section 1.2.

         Y =     the number of shares covered by this Warrant in respect of
                 which the net issue election is made pursuant to this 
                 Section 1.2.

         A =     the fair market value of one share of Common Stock, as
                 determined in accordance with the provisions of this 
                 Section 1.2.

         B =     the Per Share Exercise Price in effect under this Warrant at
                 the time the net issue election is made pursuant to this
                 Section 1.2.

For purposes of this Section 1.2, the "fair market value" per share of the
Company's Common Stock shall mean the last reported sale price of the Common
Stock on the last business day before the effective date of exercise of the net
issue election.

         2.      Reservation of Warrant Shares.  The Company agrees that, prior
to the expiration of this Warrant, the Company will at all times have
authorized and in reserve, and will keep available, solely for issuance or
delivery upon the exercise of this Warrant, the shares of the Common Stock and
other securities and properties as from time to time shall be receivable upon
the exercise of this Warrant.

         3.      Adjustments.

                 3.1      Distribution With Respect to Common Stock.  If, at
any time or from time to time after the date of this Warrant, the Company shall
distribute to the holders of the Common Stock, without payment therefor, (i)
securities, other than shares of the Common Stock, or (ii) property, other than
cash, with respect to the Common Stock, then, and in each such case, subject to
Section 3.4 below, the Holder, upon the exercise of this Warrant, shall be
entitled to receive the securities and properties which the Holder would hold
on the date of such exercise if, on the date of such distribution, the Holder
had been the holder of record of the number of shares of the Common Stock
subscribed for upon such exercise and, during the period from the date of such
distribution to and including the date of such exercise, had retained such
shares and the securities and properties receivable by the Holder during such
period.

                 3.2      Stock Splits, Etc.  If, at any time or from time to
time after the date of this Warrant, the Company shall issue to the holders of
the Common Stock shares of the Common Stock by way of a stock dividend or stock
split, then, and in each such case, the Per Share Exercise Price shall be
adjusted, or further adjusted, to a price (to the nearest whole cent)
determined by dividing (i) an amount equal to the number of shares of the
Common Stock outstanding immediately prior to such issuance multiplied by the
Per Share Exercise Price as it existed immediately prior to such issuance by
(ii) the total number of shares of the Common Stock outstanding immediately
after such issuance.  Upon each such adjustment in the Per Share Exercise
Price, the number of Warrant Shares shall be adjusted by dividing the Aggregate
Exercise Price by the Per Share Exercise Price in effect immediately after such
adjustment.

                 3.3      Reverse Splits, Etc.  If, at any time or from time to
time after the date of this Warrant, the number of shares of Common Stock
outstanding is decreased by way of combination of shares or reserve split,
then, and in each such case, the Per Share Exercise Price shall be adjusted, or
further adjusted, to a price (to the nearest whole cent) determined by dividing
(i) an amount equal to the number of shares of the Common Stock outstanding
immediately prior to such event multiplied by the Per Share Exercise Price as
it existed immediately prior to such event by (ii) the total number of shares
of the Common Stock outstanding immediately after such event.  Upon each such
adjustment in the Per Share Exercise Price, the number of Warrant Shares shall
be adjusted by dividing the Aggregate Exercise Price by the Per Share Exercise
Price in effect immediately after such adjustment.

                 3.4.     Adjustment for Reorganization, Consolidation, Merger,
                          etc.

                          a.      Reorganization, Consolidation, Merger, etc.
In case at any time or from time to time, the Company shall (i) effect a
reorganization, (ii) consolidate with or merge into any other entity or person,
or (iii) transfer all or substantially all of its properties or assets to any
other entity or person under any plan or arrangement contemplating the
dissolution of the Company, then, in each such case, the Holder, on the
exercise hereof as provided in Section 1 at any time after the consummation of
such reorganization, consolidation or merger or the effective date of such
reorganization, consolidation or merger, as the case may be, shall receive, in
lieu of the Common Stock (or other securities) issuable on such exercise prior
to such consummation or such effective date, the stock and other securities and
property (including cash) to which the Holder would have been entitled upon
such consummation or in connection with such dissolution, as the case may be,
if the Holder had so exercised this Warrant, immediately prior thereto, all
subject to further adjustment thereafter as provided in this Section 3.

                          b.      Dissolution.  In the event of any dissolution
of the Company following the transfer of all or substantially all of its
properties or assets, the Company, prior to such dissolution, shall at its
expense deliver or cause to be delivered the stock and other securities and
property (including cash, where applicable) receivable by the Holder after the
effective date of such dissolution pursuant to this Section 3.4 to a bank or
trust company having its principal office in Orange County, California, as
trustee for the Holder.

                          c.      Continuation of Terms.  Upon any
reorganization, consolidation, merger or transfer (and any dissolution
following any transfer) referred to in this Section 3.4, this Warrant shall
continue in full force and effect, subject to expiration in accordance with
Section 1 hereof, and the terms hereof shall be applicable to the shares of
stock and other securities and property receivable on the exercise of this
Warrant after the consummation of such reorganization, consolidation or merger
or the effective date of dissolution following any such transfer, as the case
may be, and shall be binding upon the issuer of any such stock or other
securities, including, in the case of any such transfer, the entity or person
acquiring all or substantially all of the properties or assets of the Company,
whether or not such entity or person shall have expressly assumed the terms of
this Warrant.

                          d.      Notice.  The Company shall provide advance
notice to the Holder of any reorganization, consolidation, merger, dissolution
or other such transaction as soon as practicable, but in no event less than 20
days prior to the consummation of any such transaction.

         4.      Fully Paid Stock; Taxes.  The Company agrees that the shares
of the Common Stock represented by each and every certificate for Warrant
Shares delivered on the exercise of this Warrant shall, at the time of such
delivery, be validly issued and outstanding, fully paid and non-assessable.
The Company further covenants and agrees that it will pay, when due and
payable, any and all federal and state stamp, original issue or similar taxes
which may be payable in respect of the issue of any Warrant Share or
certificate therefor; provided, 


                                       4

however, that the Company shall not be required to pay any tax which may be 
payable in respect of any transfer involved in the issuance of any certificate 
for Warrant Shares in a name other than that of the Holder upon any exercise 
of this Warrant.

         5.      Restrictions on Transferability of Securities; Compliance with
                 Securities Act.

                 5.1      Restrictions on Transferability.  The transferability
of this Warrant and the Warrant Shares (as well as any other securities issued
in respect of the Warrant Shares upon any stock split, stock dividend,
recapitalization, merger, consolidation or similar event) shall be subject to
the conditions specified in this Section 5, which conditions are intended to
ensure compliance with the provisions of the Securities Act of 1933 (the "Act")
and applicable state securities laws.  The Holder, and any transferee of this
Warrant or the Warrant Shares, by its acceptance hereof or thereof, agrees that
this Warrant and the Warrant Shares will be taken and held subject to the
provisions and upon the conditions specified in this Section 5.

                 5.2      Restrictive Legend.  This Warrant and each
certificate representing (i) the Warrant Shares or (ii) any other securities
issued in respect of the Warrant Shares upon any stock split, stock dividend,
recapitalization, merger, consolidation or similar event, shall (unless
otherwise permitted or unless the securities evidenced by such certificate
shall have been registered under the Act) be stamped or otherwise imprinted
with a legend substantially in the following form (in addition to any legend
required under applicable state securities laws), and shall be subject to the
provisions thereof:

                                  Borrower may request that Silicon debit the
                                  Borrower's bank account with Silicon for such
                                  amount, provided Borrower has immediately
                                  available funds in such amount in its bank
                                  account.

                                  Borrower may provide, by written notification
                                  to Silicon, instructions to terminate any of
                                  the Exchange Contracts, except that Borrower
                                  may not terminate an Exchange Contract within
                                  two business days of the date delivery is to
                                  be effected or settlement allowed.  Further,
                                  Silicon may, in its discretion, terminate the
                                  Exchange Contracts at any time (a) that an

                                  Foreign Exchange Reserve.  If either Silicon
                                  or Borrower terminates the Exchange

                                  thereto or arising in connection therewith.

                                  Borrower shall not permit the total gross

                                  delivery is to be effected and settlement

                                  Contracts to which Borrower is a party,
                                  outstanding at any one time, to exceed
                                  $2,000,000.

                                  connection with the Exchange Contracts, and

                                  applications and agreements, the Borrower
                                  will pay all standard fees and charges of

                                  from time to time, provided that with respect
                                  to Term Loans the interest rate shall be a
                                  rate equal to the "Prime Rate" in effect from
                                  time to time plus 1.00% per annum (the "Term
                                  Loan Rate").  Interest shall be calculated on

                                  Silicon are based, and it is not necessarily
                                  the best rate available at Silicon.  The
                                  interest rate applicable to the Obligations
                                  shall change on each date there is a change

                                  liens on Borrower's fixed assets that have
                                  been incurred in the usual course of the
                                  Borrower's business that are acceptable to
                                  Silicon.
