                                   (unaudited)

NOTE 1.   Summary of Significant Accounting Policies

Basis of presentation.  The accompanying financial statements have been prepared
pursuant to the rules and regulations of the Securities and Exchange  Commission
("SEC").  Certain  information  and footnote  disclosures  normally  included in
annual  financial  statements  prepared in accordance  with  generally  accepted
accounting  principles have been condensed or omitted pursuant to those rules or
regulations.  The interim  financial  statements are unaudited,  but reflect all
adjustments which are, in the opinion of management, necessary to present a fair
statement  of  results  for  the  interim  periods  presented.  These  financial
statements  should be read in conjunction with the financial  statements and the
notes  thereto in the  Company's  Annual  Report on Form 10-K for the year ended
December  27, 1998.  The results of  operations  for the interim  period are not
necessarily indicative of results to be expected in future periods.

Inventories.  Inventories are stated at the lower of cost (first-in,  first out)
or market (estimated net realizable value). All figures are in thousands.

Recently issued accounting standards. In June 1998, the FASB issued Statement of
Accounting Standards No. 133, Accounting for Derivative  Instruments and Hedging
Activities.  The Company expects to adopt the new Statement effective January 1,
2000.  The Statement  will require the  recognition  of all  derivatives  on the
Company's consolidated balance sheet at fair value. The Company anticipates that
the adoption of this Statement will not have a significant impact on its results
of operations or financial position.

NOTE 2.  Segment Information

The Company has two operating segments:  networking and non-networking products.
The networking  segment consists of  internetworking  semiconductor  devices and
related  technical  service and support to  equipment  manufacturers  for use in
their  communications  and  networking  equipment.  The  non-networking  segment
includes  custom  user  interface  products.   The  Company  is  supporting  the
non-networking  products for existing customers,  but has decided not to develop
any further products of this type.

The accounting  policies of the segments are the same as those  described in the
summary of significant  accounting policies.  The Company evaluates  performance
based on revenues and gross margins from operations of the two segments.

NOTE 4.  Sale of Investments

During the quarter ended June 27, 1999, the Company recognized a pre-tax gain of
$12.3 million  related to the  disposition of its  investment in IC Works,  Inc.
("ICW").  ICW was  purchased  by  Cypress  Semiconductor,  Inc.  ("Cypress"),  a
publicly  held  company.  As  part of the  purchase  agreement  between  ICW and
Cypress,  the Company's preferred shares in ICW, with a nominal book value, were
exchanged for 923,600  common shares of Cypress  which,  at the time, had a fair
market value of approximately $8.6 million. The Company then sold 831,240 of the
Cypress common shares  resulting in a total pre-tax gain of $ 12.3 million.  The
remaining   92,360   Cypress   common  shares  are  subject  to  certain  escrow
restrictions,  are not available for sale in 1999 and are carried at the nominal
book value of the Company's original investment in ICW.

During the quarter ended June 27, 1999, a Company's  investee,  Sierra  Wireless
Inc.  ("Sierra  Wireless"),  completed  an initial  public  offering  ("IPO") in
Canada.  As part of this IPO, the Company's  investment in non-voting  preferred
shares of Sierra Wireless were exchanged for 5.1 million common shares of Sierra
Wireless,  of which 1.7 million  shares were sold as part of the  offering for a
pre-tax gain of approximately $14.5 million.
<PAGE>

Immediately subsequent to the IPO, the Company held 3.4 million common shares of
Sierra Wireless,  representing approximately 24% of Sierra Wireless' securities.
Accordingly,  commencing  in the third  quarter of 1999,  the Company will begin
accounting  for its  investment  in Sierra  Wireless  under the equity method of
accounting. The common shares of Sierra Wireless held by the Company are subject
to certain resale restrictions and are not available for sale during 1999.


NOTE 5. Stock Split

On April 30, 1999, the Company effected a two-for-one stock split in the form of
a stock  dividend.  Accordingly,  all references to share and per-share data for
all periods presented have been adjusted to reflect this event.

Results of Operations

Second Quarters of 1999 and 1998

Net Revenues ($000,000)
- -----------------------
                                              Second Quarter
                                       ---------------------------
                                            1999           1998       Change

Networking products                     $     54.5      $    32.6       67%

Non-networking products                        4.8            7.4      (35)%
                                       ------------    -----------
Total net revenues                      $     59.3         $ 40.0       48%
                                       ============    ===========


Net revenues increased by 48% in the second quarter of 1999 compared to the same
quarter in 1998. Our networking revenue increased 67% in the same periods, which
more than offset the 35% decline in non-networking revenues.

Networking  revenues  increased  as  a  result  of  additional  demand  for  our
customers' broadband  equipment,  an increase in our customers' purchases of our
standard merchant market chips over custom-made  chips, and our introduction and
sale of chips addressing additional network functions.

Non-networking revenue continued to decline consistent with our decision to exit
all   non-networking   product  lines  while  supporting   existing   customers.
Non-networking  product revenues did increase  compared to the first quarter but
that  was  as  a  result  of  shipments  to  existing   customers  for  existing
applications  and  does  not  represent  a  sustainable  long-term  increase  in
non-networking product revenues.


Gross Profit ($000,000)
- -----------------------
                                            Second Quarter

Networking                             $     44.0    $    26.3          67%
Non-networking                                2.2          3.7         (41)%
                                      ------------  -----------
Total gross profit                     $     46.2    $    30.0          54%
                                      ============  ===========
   Percentage of net revenues                 78%          75%

Total gross profit grew 54% from $30.0 million in the second  quarter of 1998 to
$46.2 million in the same quarter of 1999.  Consistent  with our results in past
quarters, the increase in sales of higher gross margin networking semiconductors
more  than  offset  the  decline  in  gross  profit  due  to  the  reduction  in
non-networking revenue.

Gross profit as a percentage of net revenue  increased in the second  quarter of
1999 over the  comparable  period in 1998 as our  relatively  high gross  margin
networking products comprised a higher percentage of total revenue.
<PAGE>

Our  networking  gross profit as a percentage of net revenue is high relative to
the overall semiconductor industry because our products are complex and are sold
in  relatively  low  volumes.  We believe our gross  profit as a  percentage  of
revenue  will decline as our products  mature and if our  customers  purchase in
greater volume.  We expect  networking gross margins to decline if reductions in
production  costs  do not  offset  decreases  in the  average  selling  price of
existing networking products.

Non-networking  gross profit as a percent of non-networking  revenue declined in
the  second  quarter  of 1999  compared  to the same  period  in  1998.  Further
reductions may occur in the future.

Acquisition of in process
research and development                      $    -        $ 39.2

Research and Development ("R&D") expenses of $12.8 million in the second quarter
of 1999 increased 64% over last year's second quarter. We incur R&D expenditures
in an effort to attain technological  leadership from a multi-year  perspective.
This has caused R&D  spending to fluctuate  from  quarter to quarter.  We expect
such  fluctuations,  particularly when measured as a percentage of net revenues,
to occur in the future,  primarily due to the timing of expenditures and changes
in the level of net revenues.

Marketing, general and administrative expenses incurred in the second quarter of
1999 increased in dollars but decreased as a percentage of net revenue  compared
to the second quarter of 1998. In the short term, many of the marketing, general
and administrative  expenses are fixed, causing a decline as a percentage of net
revenues in periods of rapidly  rising  revenues and an increase as a percentage
of net revenue when revenue growth is slower or declining.

Goodwill  amortization  increased  to  $313,000  in the  second  quarter of 1999
compared to  $186,000  in last  year's  second  quarter.  The  increase  relates
primarily to our 1998 acquisition of Integrated Telecom Technology, Inc.

In the  second  quarter  of 1998 we  recorded  a $39.2  million  charge  for the
acquisition  of in process  research and  development  primarily  related to the
Integrated Telecom Technology,  Inc.  acquisition.  We did not record comparable
charges in 1999.



<PAGE>


Interest and other income, net
- ------------------------------

Net interest and other income increased to $1.1 million in the second quarter of
1999 from $0.8 million in last year's  second  quarter  primarily  due to higher
cash balances available to invest and earn interest and reduced interest expense
due to a lower level of capital leases.

Gain on sale of investments
- ---------------------------

During  the  quarter  ended  June  27,  1999,  we  realized  a  pre-tax  gain of
approximately  $12.3 million as a result of the disposition of our investment in
IC Works,  Inc.  ("ICW").  ICW was  purchased  by  Cypress  Semiconductor,  Inc.
("Cypress").  As part of this  purchase,  we received  Cypress  common shares in
exchange for our  investment in preferred  shares of ICW. We  subsequently  sold
831,240  Cypress  common  shares.  See  Note  4 of  the  Consolidated  Financial
Statements.

We also  realized a pre-tax gain of  approximately  $14.5  million in the second
quarter of 1999  related to our  investment  in Sierra  Wireless  Inc.  ("Sierra
Wireless").  During the quarter,  Sierra  Wireless  completed an initial  public
offering in Canada.  As part of this initial public  offering,  we exchanged our
investment in  non-voting  preferred  shares of Sierra  Wireless for 5.1 million
common  shares,  of which 1.7 million  were sold as part of the  offering  for a
pre-tax  gain  of  $14.5  million.  See  Note  4 of the  Consolidated  Financial
Statements.

Provision for income taxes
- --------------------------

The provision for income taxes consists primarily of estimated taxes on Canadian
and other foreign operations. Approximately $20.7 million of the gain on sale of
investments  recorded in the second quarter of 1999 relates to investments  held
in the United  States.  This gain was  largely  offset by our United  States net
operating  loss  carryforward.  The second quarter 1998 write-off of acquired in
process  research and  development as well as the goodwill  amortization in both
years are not deductible for tax purposes.


First Six Months of 1999 and 1998

Net Revenues ($000,000)

Total net revenues                   $    109.4    $    74.3          47%
                                    ============  ===========


Net revenues of $109.4  million in the first half of 1999 increased 47% over the
comparable  period  in 1998.  A 68%  increase  in our  networking  semiconductor
revenue more than offset a 43% decline in non-networking products.

   Percentage of net revenues                78%          76%


Total gross profit increased 52% from $56.2 million in the first half of 1998 to
$85.4  million in this year's first half.  Gross profit  increased  more rapidly
than the  increase in net  revenues  due to  increased  sales of our  networking
products as compared to sales of our  non-networking  products.  Our  networking
products  are  generally  sold for  higher  gross  margins  than  non-networking
products.  Margins on our networking and  non-networking  products declined from
82.0% and 47.8% in the first half of 1998 to 80.4% and 46.6% respectively in the
first half of 1999. We expect our gross margins to decline further.

Acquisition of in process
research and development                      $    -       $ 39.2


R&D  expenses  increased in both dollars and as a percent of net revenues in the
first half of 1999  compared  to last  year's  first  half.  We made a strategic
decision  mid-year in 1998 to increase our  targeted  spending on R&D to address
additional market opportunities for our products.

Marketing, general and administrative expenses increased in dollars but declined
as a percentage  of net revenues in the first half of 1999 compared to the first
half  of  1998.  In  the  short  term,  many  of  the  marketing,   general  and
administrative  expenses are fixed,  causing them to decline as a percentage  of
net  revenues  in  periods of  rapidly  rising  revenues  and to  increase  as a
percentage of net revenue when revenue growth is slower or declining.

Goodwill  amortization  increased  to  $626,000  in the first  half of 1999 from
$261,000 in the comparable  period in 1998. The increase is related primarily to
our 1998 acquisition of Integrated Telecom Technology, Inc.
<PAGE>


Interest and other income, Net
- ------------------------------

Net interest and other income  increased  from $1.6 million in the first half of
1998 to $2.1  million  in the first  half of 1999 due to the same  factors  that
increased net interest income for the three months ended June 27, 1999.


Liquidity and Capital Resources

Cash, cash equivalents and short term  investments  increased from $84.8 million
at the end of 1998 to $149.9 million at June 27, 1999.

During the first six months of 1999, operating activities provided $45.3 million
in cash and included $7.9 million of depreciation and $1.8 million  amortization
of intangibles. Our year to date investing activities provided $62.8 million and
includes $41.1 million of net sales of short term investments,  $28.6 million in
proceeds from the sale of equity investments, and $10 million spent on plant and
equipment  purchases.  Our financing  activities used $1.9 million,  as debt and
lease repayments of $7.1 million exceeded the $5.2 million in proceeds from sale
of common stock through our stock option and purchase plans.

Our principal source of liquidity at June 27, 1999 was our cash, cash equivalent
and short term  investment  of $149.9  million.  We also have an unused  line of
credit with a bank that allows us to borrow up to $15  million  provided,  along
with other restrictions,  that we do not pay cash dividends or make any material
divestments without the bank's written consent.

We  believe  that  existing  sources of  liquidity  and  anticipated  funds from
operations will satisfy our projected  working  capital and capital  expenditure
requirements  through  the end of 1999.  We  expect to spend  approximately  $22
million on new capital additions over the balance of 1999.

Our future capital  requirements will depend on many factors.  These include the
rate  at  which  we  develop  products  or  acquire   businesses,   products  or
technologies.  If we do not own or  generate  sufficient  resources  to fund our
operations, we may be forced to raise additional funds through public or private
debt or equity  financing.  If we issue  additional  equity,  we will reduce the
percentage  of ownership of our current  stockholders.  In addition,  additional
issued  equity  may  have  a  senior  interest  to  the  stock  of  our  current
stockholders.  If  sufficient  funds are not  available,  we may be  required to
delay, limit or eliminate some or all of our activities.

FACTORS THAT YOU SHOULD CONSIDER BEFORE INVESTING IN PMC-SIERRA
- ---------------------------------------------------------------

Our  company is  subject  to a number of risks - some are normal to the  fabless
networking  semiconductor  industry,  some  are the  same or  similar  to  those
disclosed in previous SEC  filings,  and some may be present in the future.  You
should carefully  consider all of these risks and the other  information in this
report before investing. The fact that certain risks are endemic to the industry
does not lessen the significance of the risk.

As a result of these  risks,  our  business,  financial  condition  or operating
results could be  materially  adversely  affected.  This could cause the trading
price of our  common  stock  to  decline,  and you may lose  part or all of your
investment.


OUR OPERATING RESULTS FLUCTUATE
- -------------------------------

Our  operating  results  have  fluctuated  in the past and may  fluctuate in the
future for any of the following reasons:


o     our product introduction timing;

o     our customers' inventory levels fluctuate;

o     demand for our and our customers' products changes;

o     our suppliers' product and capacity availability changes;

o     our product manufacturing yields change;

o     market acceptance or rejection of one or more of our products;

o     our average selling prices change;

o     our customers are acquired or divested;

o     a networking industry downturn occurs;

o     we are unable to acquire wafer or other manufacturing capacity;

o     our competitors produce new products or technologies;

o     our product and process development expenditures change; and

o     our competitors change prices.



WE ANTICIPATE LOWER MARGINS ON MATURE AND HIGH VOLUME PRODUCTS
- --------------------------------------------------------------

Our gross and  operating  margins may change in the future as a result of any of
the following:

o     changes in average selling prices;

o     changes in production and wafer and other supply costs; and

o     changes in our product mix.


We expect the average selling prices of our products to decline as they mature.

Historically,  competition  in the  semiconductor  industry  has driven down the
average selling prices ("ASPs") of products.  If we price our products too high,
our customers may use a competitor's product or an in-house solution.  Thus, our
ASPs will generally fall with the industry norms. To maintain profit margins, we
must reduce our costs  sufficiently  to offset declines in ASPs, or successfully
sell  proportionately  more  new  products  with  higher  ASPs.  Yield  or other
production  problems,  or shortages  of supply may preclude us from  lowering or
maintaining  current  operating  costs.  Also,  competitive,  market  and  other
pressures may not allow us to increase our sales of our higher ASP products.
<PAGE>

In  addition,  we are  entering  into  the  ethernet  market  of the  networking
industry.  Average volumes that are higher and gross margins that are lower than
the  market in which we  currently  participate  characterize  this  market.  To
maintain our current operating  margins,  we will have to sell higher volumes of
these  chips than in our  traditional  markets.  If we sell  these  chips in low
volumes, our operating margins may be adversely affected.


WE NEED TO SUCCESSFULLY DEVELOP AND INTRODUCE OUR NEW PRODUCTS
- --------------------------------------------------------------

The success of our new products depends on a number of factors, including:

o     our definition of new products to meet customer requirements;

o     our completion of product  development and introduction of new products to
      market in a timely manner;

o     our ability to judge product demand;

o     competitive pricing and performance levels; and

o     suitable fabrication yields by our independent foundries.

Many of these factors are outside our control. We may not be able to effectively
accomplish those factors that are in our control.

Some of our products adhere to specifications  developed by industry groups. For
example, in the second half of 1998, we introduced two packet-over-Sonet devices
based on specifications developed by an industry group. These specifications may
not reach sufficient  acceptance by the market to allow our products  commercial
success.

We recently  introduced a number of new ethernet  switch products which function
at gigabit and fast  ethernet  speeds.  These  products may not be  sufficiently
accepted by the market to achieve commercial success.

In May 1998,  we acquired  in-process  research and  development  and  developed
technology  related to ATM segmentation and reassembly as well as ATM switching.
It is possible that these products may not achieve volumes  sufficient to assure
their commercial success.


WE OPERATE IN AN INDUSTRY SUBJECT TO RAPID TECHNOLOGICAL CHANGE
- ---------------------------------------------------------------

We sell  products to a market whose  characteristics  include  rapidly  evolving
industry  standards,  product  obsolescence,  and new  manufacturing  and design
technologies.  Our complex  semiconductors  require extensive design and testing
before prototypes can be manufactured.  They often need to be redesigned because
manufacturing  yields on prototypes are unacceptable or customers redefine their
products  to  meet  changing  industry  standards.  Many  of the  standards  and
protocols for our products are based on high speed networking  technologies that
have not been widely  adopted or ratified by one of the standard  setting bodies
in our  customers'  industry.  Our  customers  often delay or alter their design
demands during this standard-setting  process. In response, we must redesign our
products to suit these changing demands.  Redesign usually delays the production
of our products.  Our products may become obsolete due to these rapidly evolving
industry standards and customer preferences.

<PAGE>

WE DEPEND ON THE ATM TELECOMMUNICATIONS AND NETWORKING MARKET
- -------------------------------------------------------------

We focus a  significant  part of our business and research  expenditures  in the
Asynchronous Transfer Mode ("ATM")  telecommunications and networking market. As
a result of our 1996 restructuring,  revenues from non-networking  products have
declined  significantly  over the last several years,  making our results depend
primarily on ATM and related  products.  The percentage of net revenues to total
company  sales  derived from sales of ATM,  T1/E1,  DS3/E3 and  SONET/SDH  based
products amounted to 86% in 1998 compared to 67% in 1997.

The ATM  market  is in an early  stage of  deployment.  If the  industry  adopts
industry  standards  that  compete  with  ATM,  our ATM  products  could be made
unmarketable  or obsolete.  The market for ATM  equipment  has not  developed as
rapidly as  industry  observers  had  originally  predicted,  while  alternative
networking  technologies such as "packet-over-SONET" and "gigabit ethernet" have
developed to meet networking requirements.


WE FACE FIERCE COMPETITION
- --------------------------

The markets for our  products  are  intensely  competitive  and subject to rapid
technological  change  and  price  erosion.  We  may  not  be  able  to  compete
successfully against current or future competitors.

We believe that our ability to compete successfully in these markets depends on:

o     our product performance, quality and pricing;

o     our, our competitors' and our customers' timing and success of new product
      introductions;

o     our ability to innovate;

o     our ability to deliver working  products on schedule;

o     market acceptance of standards for which we have produced products;

o     our ability to obtain adequate manufacturing capacity;

o     our subcontractors'  production efficiency;

o     the rate at which  our  customers  incorporate  our  products  into  their
      designs; and

o     our and our competitors' assertion of intellectual property rights.

We typically face  competition  at the design stage,  where  customers  evaluate
alternative design approaches that require integrated circuits.  Our competitors
have  increasingly  frequent  opportunities  to  supplant  our  products in next
generation  systems  because of shortened  product life and design-in  cycles in
many of our customers' products.
<PAGE>

Our competitors are major domestic and  international  semiconductor  companies,
many of which have substantially  greater financial and other resources than us.
Emerging  companies also provide  significant  competition in our segment of the
semiconductor   market.   Our  competitors   include   Advanced  Micro  Circuits
Corporation,   Broadcom,   Conexant  Systems,   Cypress  Semiconductor,   Dallas
Semiconductor,  Galileo Technology,  Integrated Device Technology,  Intel, Level
One Communications,  Lucent Technologies, Motorola, MMC Networks, Siemens, Texas
Instruments,  Transwitch and Vitesse Semiconductor.  Over the next few years, we
expect additional competitors, some of which also may have greater financial and
other  resources,  to enter the market with new  products.  In addition,  we are
aware of a number of  venture-backed  companies  that each  focus on a  specific
portion of our broad  range of  products.  These  companies  collectively  could
represent future competition for many design wins, and subsequent product sales.


WE MUST HAVE ACCESS TO THE KEY SUPPLIERS ON WHICH WE RELY
- ---------------------------------------------------------

We do not own or operate a wafer  fabrication  facility.  Two outside  foundries
supply all our  semiconductor  device  requirements.  Our foundry suppliers also
produce products for themselves and other  companies.  We may not have access to
adequate  capacity or certain  process  technologies.  We have less control over
delivery schedules,  manufacturing  yields and costs than competitors with their
own fabrication  facilities.  If the foundries we use are unable or unwilling to
manufacture  our  products in  required  volumes,  we may have to  identify  and
qualify  acceptable  additional or  alternative  foundries.  This  qualification
process could take six months or longer. We may not find enough capacity quickly
enough, if ever, to satisfy our production requirements.

Sub-assemblers in Asia assemble all of our semiconductor  products. Raw material
shortages, political and social instability, assembly house service disruptions,
currency  fluctuations,  or other  circumstances in the region could force us to
seek additional or alternative sources of supply or assembly. This could lead to
supply  constraints or product delivery delays which, in turn, may result in the
loss of  customers.  We have less  control  over  delivery  schedules,  assembly
processes,  quality  assurances and costs than competitors that do not outsource
these tasks.

A limited number of suppliers provide the computer aided design ("CAD") software
we use to design our  products.  Factors  affecting the price,  availability  or
technical  capability  of these  products  could  affect  our  ability to access
appropriate  CAD  tools  for the  development  of highly  complex  products.  In
particular,  the CAD  software  industry  has  been  the  subject  of  extensive
intellectual  property rights litigation,  the results of which could materially
change the pricing and nature of the  software we use. We also have less control
over whether our software suppliers will be able to breach technical barriers in
time to fulfill our needs.


OUR CUSTOMER BASE IS CONCENTRATED
- ---------------------------------

We depend on a limited  number of customers for a major portion of our revenues.
Through direct,  distributor and subcontractor  purchases,  Lucent  Technologies
(including Ascend Communications) and Cisco Systems each accounted for more than
10% of our  fiscal  1998  revenues.  We do not have  long-term  volume  purchase
commitments  from any of our major  customers.  Our customers often shift buying
patterns as they manage inventory levels,  decide to use competing products,  or
change their orders for other  reasons.  If one or more customers were to delay,
reduce or cancel orders, our overall order levels may fluctuate greatly.

<PAGE>

OUR GLOBAL BUSINESS APPROACH SUBJECTS US TO ADDITIONAL RISKS
- ------------------------------------------------------------

We are subject to a number of risks of conducting business outside of the United
States.
Historically, international sales accounted for the following percentages of our
net revenues:  32% in 1998, 30% in 1997 and 46% in 1996. We expect international
sales will continue to represent a significant portion of our and our customers'
net revenues for the foreseeable future.

We are subject to these risks to a greater extent than most  companies  because,
in addition to selling our  products  in a number of  countries,  a  significant
portion of our research and development and  manufacturing are conducted outside
of the United  States.  The majority of our  development,  test,  marketing  and
administrative  functions occur in Canada and  substantially all of our products
are manufactured and assembled by independent third parties in Asia.

Our international sales,  research and development and manufacturing may subject
us to the following risks:

o     changes to, or impositions of, legislative or regulatory  requirements and
      policy changes affecting the networking market;

o     delays  resulting from difficulty in obtaining export licenses for certain
      technology,  tariffs,  quotas, exchange rates and other trade barriers and
      restrictions;

o     foreign  currency  rate  fluctuations   because  our  development,   test,
      marketing and  administrative  costs are denominated in Canadian  dollars,
      and our selling costs are denominated in a variety of currencies;

o     greater difficulty in accounts receivable collection;

o     longer payment cycles;

o     taxes;

o     political, social and economic instability;

o     hostilities and changes in diplomatic and trade relationships; and

o     the burdens of complying with a variety of foreign laws and communications
      standards.


WE DEPEND ON KEY PERSONNEL
- --------------------------

We must  retain  and hire key  technical  personnel  to be  successful.  This is
particularly  true with respect to those employees who are highly skilled at the
design and test  functions  used to develop high speed  networking  products and
related  software.  The  competition for such employees is intense and we do not
have  employment  agreements in place with these key personnel.  We issue common
stock options that are subject to vesting as employee incentives. These options,
however, are effective as retention incentives only if they have economic value.


OUR PRODUCTS EMPLOY PROPRIETARY TECHNOLOGY THAT WE MAY NOT BE ABLE TO PROTECT
- -----------------------------------------------------------------------------

To compete effectively,  we must protect our proprietary information. We rely on
a  combination   of  patents,   trademarks,   copyrights,   trade  secret  laws,
confidentiality   procedures   and   licensing   arrangements   to  protect  our
intellectual  property  rights.  We hold  several  patents  and have a number of
pending patent applications.

We might not succeed in attaining patents from any of our pending  applications.
Even if we are awarded patents,  they may not provide any meaningful  protection
or  commercial  advantage  to us,  as they  may not be of  sufficient  scope  or
strength,  or may not be issued in all countries where our products can be sold.
In addition, our competitors may be able to design around our patents.

We develop,  manufacture and sell our products in Asian and other countries that
may not protect our products or intellectual  property rights to the same extent
as the laws of the  United  States.  This  makes  piracy of our  technology  and
products more likely.  Steps we take to protect our proprietary  information may
not be  adequate  to  prevent  theft  of our  technology.  We may not be able to
prevent our competitors  from  independently  developing  technologies  that are
similar to or better than ours.


WE MAY BE LEFT WITH UNSALEABLE INVENTORY
- ----------------------------------------

We attempt to forecast  and maintain a level of  inventory  in  anticipation  of
demand for our products.  Anticipating demand is difficult because our customers
face volatile pricing and demand for their end-user networking equipment. If our
customers were to delay, cancel or otherwise change future ordering patterns, we
could be left with unwanted inventory.


OUR PRODUCTS EMPLOY PROPRIETARY TECHNOLOGY THAT MAY INFRINGE ON THE INTELLECTUAL
- --------------------------------------------------------------------------------
PROPERTY RIGHTS OF THIRD PARTIES
- --------------------------------

Vigorous  protection and pursuit of  intellectual  property  rights or positions
characterize  the  semiconductor  industry.  This often results in expensive and
lengthy litigation. We, as well as our customers or suppliers, may be accused of
infringing  on  patents or other  intellectual  property  rights  owned by third
parties.  This has  happened in the past.  An adverse  result in any  litigation
could force us to pay substantial damages, stop manufacturing, using and selling
the infringing products,  spend significant resources to develop  non-infringing
technology,  discontinue  using  certain  processes  or obtain  licenses  to the
infringing technology. In addition, we may not be able to develop non-infringing
technology,  nor might we be able to find  appropriate  licenses  on  reasonable
terms.

Patent  disputes  in  the  semiconductor  industry  are  often  settled  through
cross-licensing  arrangements.  Because we currently  do not have a  substantial
portfolio  of  patents,  we  may  not  be  able  to  settle  an  alleged  patent
infringement claim through a cross-licensing  arrangement. We are therefore more
exposed to third party claims than some of our competitors and customers.

In the past,  our customers  have been required to obtain  licenses from and pay
royalties  to  third  parties  for  the  sale  of  systems   incorporating   our
semiconductor  devices.  Until December of 1997, we indemnified our customers up
to the dollar amount of their  purchases of our products  found to be infringing
on technology owned by third parties.  Customers may also make claims against us
with respect to infringement.

Furthermore,  we may initiate  claims or  litigation  against  third parties for
infringing  our  proprietary   rights  or  to  establish  the  validity  of  our
proprietary  rights.  This could  consume  significant  resources and divert the
efforts  of  our  technical  and   management   personnel,   regardless  of  the
litigation's outcome.


WE MAY BE INVOLVED IN ACQUISITIONS
- ----------------------------------

We  may  acquire  products,  technologies  or  businesses  from  third  parties.
Management may be diverted from our operations while they identify and negotiate
these  acquisitions and integrate an acquired entity into our operations.  Also,
we may be forced to develop  expertise  outside  our  existing  businesses,  and
replace key  personnel who leave due to an  acquisition.  An  acquisition  could
absorb  substantial  cash  resources,   require  us  to  incur  or  assume  debt
obligations,  or issue additional equity. If we issue more equity, we may dilute
our common stock with securities that have a senior interest.

Acquired entities also may have unknown liabilities, and the combined entity may
not achieve the results that were  anticipated  at the time of the  acquisition.
Proposed  changes  to  accounting   standards  will  eliminate   in-process  R&D
write-offs.  As a result,  an  acquisition  that is accounted  for as a purchase
could  involve the  amortization  of  intangibles  and goodwill over a number of
years. The purchase method of accounting was used to record our acquisition of a
networking business in 1994, certain assets of Bipolar Integrated  Technology in
September  1996,  and the  acquisition of Integrated  Telecom  Technology in May
1998.


WE MAY NEED ADDITIONAL CAPITAL IN THE FUTURE
- --------------------------------------------

We must continue to make  significant  investments in research and  development,
capital  equipment  and  facilities  for  our  operations.  Our  future  capital
requirements will depend on many factors, including product development, working
capital investments, and acquisitions of businesses, products or technologies.

We may need to raise  additional  funds through public or private debt or equity
financing  to  fund  our  operations.  If  we  raise  funds  by  issuing  equity
securities, the percentage ownership of current stockholders will be reduced and
the new equity  securities may have priority rights to your  investment.  We may
not obtain sufficient  financing on terms we or you will find favorable.  We may
delay,  limit or eliminate  some or all of our proposed  operations  if adequate
funds are not available.


OUR STOCK PRICE HAS BEEN AND MAY CONTINUE TO BE VOLATILE
- --------------------------------------------------------

In the past,  our common stock price has fluctuated  substantially.  The reasons
this may continue include the following:

o     our or our competitors' new product announcements;

o     quarterly  fluctuations in the financial  results of our company and other
      companies in the semiconductor, networking or computer industries;

o     conditions in the networking or semiconductor industry; and

o     investor sentiment toward technology stocks.
<PAGE>

In addition, increases in our stock price and expansion of our price-to-earnings
multiple  may have made our stock  attractive  to momentum  investors  who often
shift funds into and out of stocks rapidly,  exacerbating  price fluctuations in
either direction.


YEAR 2000 COMPUTER SYSTEMS ISSUES
- ---------------------------------

The approach of the year 2000 presents  significant  issues for many  financial,
information,  and operational systems. Many systems in use today may not be able
to interpret dates after December 31, 1999  appropriately,  because such systems
allow only two digits to indicate the year in a date. As a result,  such systems
are unable to  distinguish  January 1, 2000,  from January 1, 1900,  which could
have adverse consequences on the operations of the entity.

Our State of Readiness

We have designated specific individuals to identify and resolve year 2000 issues
associated with our internal  information  technology (IT) systems, our internal
non-IT systems,  and material third party  relationships.  We have completed the
identification  of and are  implementing  our  plans to  address  our year  2000
issues.

We use commercially  available  standard software for our critical operating and
design  functions.  Our primary  software  vendors have provided program updates
that are intended to rectify the year 2000 issues related to their software.  We
upgraded all primary software by the second quarter of 1998. In addition, we are
currently  implementing  an  enterprise-wide  software  system  for  operational
reasons.  This system is scheduled to be fully  implemented  in the remainder of
1999 and is year 2000 compliant.

We have secondary design and operating software that is not year 2000 compliant.
We have  identified  and  intend to install  or  develop  patches or  workaround
solutions for this software during 1999.

We use other technology,  such as semiconductor testers, which are not year 2000
compliant.   These  systems  do  not  interface  with  our  critical   operating
applications.  We have identified these systems and expect to conclude modifying
or replacing them in 1999.

The total cost of the software  upgrade for our primary  operating and financial
applications,  the cost to purchase and install our other non-critical software,
and the cost for the  modification  and  replacement of our other  technology is
expected to be immaterial.

As of June 27, 1999, our year 2000  procedures are proceeding as planned.  Costs
of these procedures to date plus expected costs to completion are expected to be
immaterial.

Our Year 2000 Risk

Our greatest year 2000 exposure comes from our product manufacturing,  packaging
and delivery suppliers. Our worst case scenario would be if one or more critical
suppliers  fail to become  year 2000  compliant  and fail to develop  acceptable
workaround solutions.  The majority of our product manufacturing,  packaging and
delivery  is  outsourced  to two wafer  fabrication  companies,  three  assembly
companies and one shipping company, respectively.  These suppliers are generally
much larger than our  company  and we have little  influence  on their year 2000
preparedness  schedules.  While we have received written  communication from our
critical suppliers that they have developed an action plan to address their year
2000  issues,  we cannot be certain that these plans will be  implemented  or be
effective.
<PAGE>

If our suppliers are unable to manufacture our products as a result of year 2000
issues,  we may be  forced  to  find  and  qualify  other  year  2000  compliant
suppliers.  This  qualification  process could take six months or longer. We may
not  find  sufficient   capacity   quickly  enough  to  satisfy  our  production
requirements,   as  we  would  expect  that  the  many  other   companies   with
manufacturing models similar to ours would be vying for production capacity.

We are also exposed to customers who may not be year 2000  compliant.  If one or
more  of our  customers'  operations  is  interrupted  due to  year  2000  issue
non-compliance, our revenues from these customers could be materially impacted.


Our Contingency Plans

While we do not have a formal  contingency  plan, we are monitoring our critical
suppliers to ensure they complete  their year 2000 plans as scheduled.  We would
implement  a  formal  contingency  plan  should  any of our  critical  suppliers
indicate  that  there  would be any  delays  resulting  from their own year 2000
plans. Such a plan could entail contacting and qualifying other potentially year
2000 compliant suppliers and stocking  additional  inventory to cover short term
operating needs. We can not ensure that this contingency plan would be effective
or completed in a timely manner.

Item 3.   QUANTITATIVE AND QUALITATIVE DISCLOSURES
          ABOUT MARKET RISK

The following  discussion  regarding  our risk  management  activities  contains
"forward-looking  statements"  that  involve  risks  and  uncertainties.  Actual
results  may differ  materially  from  those  projected  in the  forward-looking
statements.

We are exposed to foreign currency fluctuations through our operations in Canada
and  elsewhere.  In our effort to hedge this risk,  we  typically  forecast  our
operational  currency  needs,  purchase  such currency on the open market at the
beginning of an operational  period, and classify these funds as a hedge against
operations.  We usually  limit the  operational  period to less than 3 months to
avoid  undue  exposure  of  our  asset  position  to  further  foreign  currency
fluctuation.  While we expect to  utilize  this  method of hedging  our  foreign
currency risk in the future,  we may change our hedging  methodology and utilize
foreign  exchange  contracts  which are currently  available under our operating
line of credit agreement.

Occasionally, we may not be able to correctly forecast our operational needs. If
our  forecasts  are  overstated  or  understated   during  periods  of  currency
volatility,  we could experience  unanticipated currency gains or losses. At the
end of the second quarter of 1999, we did not have significant  foreign currency
denominated  net asset or net  liability  positions,  and we had no  outstanding
foreign exchange contracts.

We  maintain  investment  portfolio  holdings  of various  issuers,  types,  and
maturity  dates with  various  banks and  investment  banking  institutions.  We
sometimes  hold  investments  beyond  120 days,  and the  market  value of these
investments on any day during the investment term may vary as a result of market
interest rate  fluctuations.  We do not hedge this exposure  because  short-term
fluctuations  in  interest  rates  would not likely  have a  material  impact on
interest  earnings.   We  classify  our  investments  as  available-for-sale  or
held-to-maturity  at the time of purchase and re-evaluate this designation as of
each balance sheet date. We had approximately  $9.8 million in outstanding short
term  investments  at the end of the second  quarter of 1999. In the future,  we
expect to hold the short-term investments we buy through to maturity.

Item 5.  DESCRIPTION OF CAPITAL STOCK


The authorized  capital stock of the Company  consists of 200,000,000  shares of
Common Stock, par value $0.001, and 5,000,000 shares of
Preferred Stock, par value $0.001.

The  following  summary of certain  provisions of the Common Stock and Preferred
Stock does not  purport to be complete  though the Company  believes it contains
all the material  provisions,  and is subject to, and  qualified in its entirety
by, the  provisions of the Company's  Certificate  of  Incorporation  and by the
provisions of applicable law.

Common Stock
- ------------

The  Company's  Common Stock is  registered  under Section 12(g) of the Exchange
Act. Subject to preferences that may be applicable to any outstanding  Preferred
Stock  which  may be issued  in the  future,  the  holders  of Common  Stock are
entitled to receive  ratably such  non-cumulative  dividends,  if any, as may be
declared  from  time to time by the  Board of  Directors  out of  funds  legally
available  therefor.  The Common Stock has no preemptive or conversion rights or
other  subscription  rights.  There are no redemption or sinking fund provisions
available to the Common  Stock.  The holders of Common Stock are entitled to one
vote per share on all matters to be voted upon by the stockholders,  except that
stockholders  may,  in  accordance  with  Section  214 of the  Delaware  General
Corporation Law, cumulate their votes in the election of directors. In the event
of liquidation,  dissolution or winding up of the Company, the holders of Common
Stock are entitled to share  ratably in all assets  remaining  after  payment of
liabilities,  subject to  liquidation  preferences,  if any, of Preferred  Stock
which may be issued in the future.  All  outstanding  shares of Common Stock are
fully paid and non-assessable.

Preferred Stock
- ---------------

Pursuant to the Company's  Certificate of Incorporation,  the Board of Directors
of the Company has the  authority to issue up to  5,000,000  shares of Preferred
Stock in one or more  series,  to fix the rights,  preferences,  privileges  and
restrictions  granted to or imposed upon any wholly unissued series of Preferred
Stock,  and to fix  the  number  of  shares  constituting  any  series  and  the
designations  of  such  series,  without  any  further  vote  or  action  by the
stockholders.  Such issued  Preferred  Stock could  adversely  effect the voting
power and other rights of the holders of Common Stock. The issuance of Preferred
Stock may also have the effect of delaying,  deferring or preventing a change in
control of the Company. At present, there are no outstanding shares of Preferred
Stock.



<PAGE>


Rights of Holders of Special Shares of PMC-Sierra, Ltd.
- -------------------------------------------------------

The Special  Shares of  PMC-Sierra,  Ltd. are redeemable for Common Stock of the
Company.  Special  Shares do not have voting  rights in the Company,  but in all
other  respects  they  represent the economic and  functional  equivalent of the
Common  Stock of the Company for which they can be  redeemed.  Under  applicable
law,  each class of Special  Shares  will have  class  voting  rights in certain
circumstances  with respect to transactions  that affect the rights of the class
and for  certain  extraordinary  corporate  transactions.  Two kinds of  Special
Shares are outstanding: A Special Shares and B Special Shares.

Delaware Law
- ------------

Section 203 of the Delaware General  Corporation Law, from which the Company has
not opted out in its Certificate of  Incorporation,  restricts certain "business
combinations" with "interested  stockholders" for three years following the date
that a person or entity becomes an interested stockholder,  unless the Company's
Board of Directors  approves  the  business  combination  and/or  certain  other
requirements are met.

                                PMC-SIERRA, INC.

                             A Delaware corporation

PMC-Sierra,  Inc.,  a  corporation  organized  under  the  laws of the  State of
Delaware (the "Corporation,,), hereby certifies that:

The name of the  Corporation is PMC-Sierra,  Inc. The Corporation was originally
incorporated with the Secretary of State of Delaware on May 2, 1997.

The first  paragraph of Article IV of the  Certificate of  Incorporation  of the
Corporation shall be amended to read as follows:

"This  Corporation is authorized to issue two classes of stock to be designated,
respectively,   "Common  Stock"  and  "Preferred   Stock."  The  Corporation  is
authorized to issue a total of 205,000,000  shares.  200,000,000 shares shall be
Common Stock,  par value $0.001,  and 5,000,000 shares shall be Preferred Stock,
par value $0.001."

Article XII of the  Certificate of  Incorporation  of the  Corporation  shall be
amended to read as follows:

"The  stockholders of the Corporation  shall not act by written consent,  except
solely to call a special  meeting of the  stockholders  in  accordance  with the
following procedures:

    Upon  request  by written  consent  of  holders  of a  majority  of the
    outstanding shares, containing the information described below, sent by
    registered mail to the president or chief executive officer,  the board
    of  directors  shall  determine a place and time for such meeting and a
    record date for the  determination of stockholders  entitled to vote at
    such  meeting.  Such  time  shall  not  be  more  than  75  days  after
    determination  of the validity of such request.  The board of directors
    shall  have no more  than 10 days  after  receipt  of such  request  to
    determine its validity. Following such receipt and determinations,  the
    secretary  shall give  notice to the  stockholders  entitled to vote at
    such  meeting  that a  meeting  will be held at the  place  and time so
    determined.

    The request by written  consent shall state each action the  requesting
    stockholders  propose to take at such  meeting.  The board of directors
    may include other proposals to be considered at such meeting.

    The   requesting   stockholders   shall  provide  to  the   Corporation
    information regarding any material interest in the proposal held by the
    requesting  stockholders  and  any  other  information  that  would  be
    required to be disclosed in filings  with the  Securities  and Exchange
    Commission in connection with the solicitation of proxies.

This  Certificate  of  Amendment of the  Corporation's  Amended  Certificate  of
Incorporation has been duly adopted by the  Corporation's  board of directors in
accordance  with  Section  242 of the  General  Corporation  Law of the State of
Delaware.

This  Certificate  of  Amendment of the  Corporation's  Amended  Certificate  of
Incorporation has been duly approved by the holders of a majority of outstanding
stock of the Corporation entitled to vote thereon in accordance with Section 242
of the General Corporation Law of the State of Delaware.

IN WITNESS WHEREOF,  the Corporation has caused this Certificate of Amendment to
Certificate of  Incorporation  to be signed by John Sullivan,  Vice President of
Finance and Chief Financial Officer, on this 12th day of July, 1999.

Description and Rate:         A revolving committed credit, for general business
                              purposes, having the following parts:

                              (1)   U.S. alternate base rate loans. The Interest
                              Rate is as follows:  U.S. Alternate Base Rate plus
                              0% per year.

                              (2)   U.S. dollar  LIBOR loans.  The Interest Rate
                              is as follows: LIBO Rate plus 1.0% per year.

                              (3)   Financial  standby  letters  of credit.  The
                              fees are  equal to 1% of the  principal  amount of
                              the L/C, plus out of pocket expenses.

Letters of Credit:            L/Cs may not have  terms to expiry of more than 12
                              months  or  beyond  the  committed  term  of  this
                              Credit.  Our  standard L/C  documentation  is also
                              required. If we issue an L/C, the available Credit
                              Limit will be  reduced by 100% of the face  amount
                              of the L/C.  If there is a drawing  under any L/C,
                              you  will   forthwith   upon  demand  pay  us  the
                              amount(s)  drawn  under the L/C. If you do not pay
                              us the amount demanded interest will accrue on the
                              amount drawn under the L/C at the Default Interest
                              Rate until the amount  drawn under the L/C is paid
                              in full,  unless you have made other  arrangements
                              with us.

Repayment/Termination:        Repayments  of  U.S.  alternate  base  rate  loans
                              and/or  LIBOR Loans must be in minimum  amounts of
                              $1,000,000  or,  if  less,  the  then  outstanding
                              amount thereof.

                              This  Credit  will expire two years after the date
                              of this Agreement,  except CIBC Inc. may from time
                              to time  renew  its  commitment  by an  additional
                              year;  provided that this Credit must be repaid in
                              full immediately upon, and further availments will
                              cease to be  available  upon,  the  earlier of the
                              expiry of the committed  term of this Credit,  the
                              occurrence of an Event of Default, or there having
                              occurred (in our  reasonable  opinion) a change in
                              effective control of your company or PMC Ltd. with
                              respect to the power to elect the  majority of the

Capital Adequacy, Etc.        change  in or in  the  interpretation  of,  or any
                              change in its application to us of, any law or any
                              regulation or guideline issued by any central bank
                              or other  governmental  authority  (whether or not
                              having  the  force  of  law),   including  without
                              limitation   any   reserve  or   special   deposit
                              requirement  or any  tax  (other  than  tax on our
                              general  income) or any capital  requirement,  has
                              (due to our  compliance)  the effect,  directly or
                              indirectly,  of (i)  increasing  the cost to us of
                              performing our obligations  hereunder or under any
                              L/C;   (ii)   reducing  any  amount   received  or
                              receivable by us hereunder or our effective return
                              hereunder or on our capital;  or (iii)  causing us
                              to make any  payment or to forgo any return  based
                              on  any  amount   received  or  receivable  by  us
                              hereunder  or in  respect  of any L/C;  then  upon
                              demand  from time to time you will pay such amount
                              as  shall   compensate   us  for  any  such  cost,
                              reduction,  payment  or forgone  return.  You will
                              further indemnify us for all out-of-pocket  costs,
                              losses and expenses  incurred by us in  connection
                              with  any L/C  and  agree  that  we  will  have no
                              liability  to you for any reason in respect of any
                              availment  other  than  on  account  of our  gross
                              negligence or wilful  misconduct.  Any certificate
                              of CIBC Inc. in respect of the  foregoing  will be
                              conclusive  and  binding  upon  you,   except  for
                              manifest  error,  provided that we shall determine
                              the  amounts  owing to us in good faith  using any
                              reasonable averaging and attribution methods.

                              L/C  which is the  subject  matter  of any  order,

                              (an "Order").  We agree that we will, with respect
                              to each such L/C, upon the later of:


                              (a) the earlier  of: (i) the date on which  either
                              the original  counterpart  of such L/C is returned
                              to us for  cancellation  or we are released by the
                              beneficiary   from  any  further   obligations  in
                              respect of such L/C;  and, (ii) the expiry of such

                              (b) the date on which any final order, judgment or
                              other  such  determination  has been  rendered  or
                              issued either terminating the applicable Order, or
                              permanently  enjoining  us from paying  under such
                              L/C;

                              pay to you an  amount  equal to any  excess of the
                              amount  received by us hereunder in respect of our
                              contingent liability under such L/C (the "Received
                              Amount")  over the  total of  amounts  applied  to
                              reimburse us for amounts paid by us under such L/C
                              (CIBC Inc. having the right to so appropriate such
                              funds),   together  with  an   additional   amount
                              computed  by applying to the amount of such excess
                              from time to time a per annum rate equal to 3% per
                              year less than the U.S.  Alternate Base Rate. Such
                              additional amount shall be calculated daily on the
                              basis of a calendar  year for the actual number of
                              days  elapsed  from  and  including  the  date  of
                              payment to us of the  Received  Amount to (but not
                              including)  the  date  of  return  to  you  of the
                              excess.

6326-95/06                      Schedule - Standard Credit

                               ARTICLE 1 - GENERAL

1.1  Interest Rate.  You will  pay interest on each Credit at nominal rates per
year equal to:

  (a) for amounts above  the Credit  Limit of a Credit or a  part of a Credit or
for amounts that are not paid when due, the Default Interest Rate, and

  (b) for any other amounts, the rate specified in this Agreement.

1.2  Variable  interest.  Each  variable  interest rate provided for under this
Agreement will change automatically,  without notice, whenever the Prime Rate or
the U.S. Alternate Base Rate, as the case may be, changes.

1.3  Payment of interest.  Interest is  calculated  on the daily  balance of the
Credit  at the end of  each  day.  Interest  is due  once a  month,  unless  the
Agreement  states otherwise and you will pay the interest when it is due. Unless
you have made other  arrangements with us regarding the payment of interest,  we
will be charging  interest on overdue  interest (which is known as compounding).
Unpaid interest  continues to compound  whether or not we have demanded  payment
from you or started a legal action, or get judgment, against you.

1.4   Default Interest.  To determine whether Default Interest is to be charged,
the following rules apply:

  (a) Default  Interest  will be charged on the amount  that  exceeds the Credit
Limit of any particular Credit.

  (b) If there are several parts of a Credit,  Default  Interest will be charged
if the Credit Limit of a particular part is exceeded. For example, if Credit A's
limit is  $250,000,  and the limit of one part is $100,000 and the limit of that
part is exceeded by $25,000,  Default  Interest  will be charged on that $25,000
excess,  even if the  total  amount  outstanding  under  Credit  A is less  than
$250,000.

1.5   Fees.  You will pay CIBC  Inc.'s  fees for each  Credit as outlined in the
Letter.  You will also reimburse us for all  reasonable  fees  (including  legal
fees) and out-of-pocket  expenses  incurred in registering any security,  and in
enforcing our rights under this Agreement or any security. We will automatically
debit your Operating Account for fee amounts owing.

1.6   Our  rights  re  demand  Credits.  At  CIBC  Inc.,  we  believe  that  the
banker-customer  relationship  is based  on  mutual  trust  and  respect.  It is
important  for us to know all the  relevant  information  (whether  good or bad)
about  your  business.  CIBC  Inc.  is  itself a  business.  Managing  risks and
monitoring  our  customers'  ability  to repay is  critical  to us.  We can only
continue to lend when we feel that we are likely to be repaid.  As a result,  if
you do something that  jeopardizes  that  relationship,  or if we no longer feel
that you are likely to repay all  amounts  borrowed,  we may have to act. We may
decide to act, for example,  because of something you have done,  information we
receive  about your  business,  or  changes  to the  economy  that  affect  your
business.  Some of the actions that we may decide to take include  requiring you
to give us more financial information, negotiating a change in the interest rate
or fees, or asking you to get further accounting assistance,  put more cash into
the business, provide more security, or produce a satisfactory business plan. It
is  important  to us  that  your  business  succeeds.  We may,  however,  at our
discretion,  demand  immediate  repayment of any  outstanding  amounts under any
demand  Credit.  We may also,  at any time and for any cause,  cancel the unused
portion of any demand Credit. Under normal circumstances,  however, we will give
you 30 days' notice of any of these actions.

1.7   Payments.  If any payment is due on a day other than a Business  Day, then
the payment is due on the next Business Day.

1.8   Applying money received. If you have not made payments as required by this
Agreement,  or if you have failed to satisfy any term of this  Agreement (or any
other agreement you have that relates to this Agreement),  or at any time before
default  but after we have given you  appropriate  notice,  we may decide how to
apply any money that we receive.  This means that we may choose  which Credit to
apply the money against,  or what mix of principal,  interest,  fees and overdue
amounts within any Credit will be paid.

1.9   Information requirements.  We may from time to time reasonably require you
to provide further  information about your business.  We may require information
from you to be in a form acceptable to us. We will use your  information only in
connection with the credits and will keep it confidential  unless required to be
disclosed by law or court order.

1.10  Insurance. You will keep all your business assets and property insured (to
the full  insurable  value)  against  loss or damage by fire and all other risks
usual for  property  such as yours (plus for any other  risks we may  reasonably
require). If we ask, you will give us either the policies themselves or adequate
evidence of their existence. If your insurance coverage for any reason stops, we
may (but do not have to) insure the property.  We will automatically  debit your
Operating Account for these amounts.  Finally, you will notify us immediately of
any loss or damage to the property.
<PAGE>

1.11  Environmental.  You will carry on your business,  and maintain your assets
and  property,  in  accordance  with  all  applicable   environmental  laws  and
regulations.  If (a) there is any  release,  deposit,  discharge  or disposal of
pollutants of any sort  (collectively,  a "Discharge") in connection with either
your business or your property, and we pay any fines or for any clean-up, or (b)
we suffer any loss or damage as a result of any  Discharge,  you will  reimburse
CIBC Inc., its directors, officers, employees and agents for any and all losses,
damages,  fines,  costs and other amounts (including amounts spent preparing any
necessary environmental  assessment or other reports, or defending any lawsuits)
that  result.  If we ask,  you  will  defend  any  lawsuits,  investigations  or
prosecutions  brought  against  CIBC  Inc.  or any of its  directors,  officers,
employees and agents in connection  with any  Discharge.  Your  obligation to us
under this  section  continues  even after all Credits have been repaid and this
Agreement has terminated.

1.12  Consent to release  information.  We may from time to time give any credit
information  about you to, or receive such  information  from, (a) any financial
institution,  credit reporting agency,  rating agency or credit bureau,  (b) any
person,  firm or corporation with whom you may have or propose to have financial
dealings,  and (c) any  person,  firm or  corporation  in  connection  with  any
dealings  you have or  propose  to have with us.  You agree that we may use that
information to establish and maintain your relationship with us and to offer any
services as permitted  by law,  including  services and products  offered by our
subsidiaries when it is considered that this may be suitable to you.

1.13  Our  pricing  policy:  Fees,  interest  rates and other  charges  for your
banking  arrangements are dependent upon each other. If you decide to cancel any
of these  arrangements,  you will have to pay us any  increased  or added  fees,
interest  rates and charges we determine  and notify you of. These  increased or
added amounts are effective from the date of the changes that you make.

1.14  Proof of debt.  This Agreement  provides the proof,  between CIBC Inc. and
you, of the credit made  available  to you.  There may be times when the type of
Credit you have requires you to sign additional  documents.  Throughout the time
that we provide you credit under this  Agreement,  our loan  accounting  records
will provide  complete proof of all terms and conditions of your credit (such as
principal loan balances, interest calculations, and payment dates).

1.15  Renewals of this Agreement.  This Agreement will remain in effect for your
Credits for as long as they  remain  unchanged.  We have shown a Next  Scheduled
Review Date in the Letter. If there are no changes to the Credits this Agreement
will continue to apply, and you will not need to sign anything further. If there
are any changes, we will provide you with either an amending agreement, or a new
replacement Letter, for you to sign.

1.16  Confidentiality:  The terms of this Agreement are confidential between you
and CIBC  Inc..  You  therefore  agree  not to  disclose  the  contents  of this
Agreement to anyone  except your  professional  advisors or (as required by law)
any regulatory or governmental body, including,  without limitation,  the United
States Securities and Exchange Commission.

1.17  Pre-conditions.  You  may  use  the  Credits  granted  to you  under  this
Agreement only if:

   (a) we have received properly signed copies of all documentation  that we may
reasonably  require  and which we have  provided to you in  connection  with the
operation of your accounts and your ability to borrow and give security;
   (b) all the  required  security  has  been  received  and  registered  to our
satisfaction;
   (c) any special  provisions or  conditions  set forth in the Letter have been
complied with; and
   (d) if applicable, you have given us the required number of days notice for a
drawing under a Credit.

1.18  Notices.  We may give you any  notice  in person  or by  telephone,  or by
letter that is sent either by fax or by mail.

1.19  Use of the Operating  Line. You will use your Operating Line only for your
business  operating  cash  needs.  You are  responsible  for all debits from the
Operating  Account  that you  have  either  initiated  (such  as  cheques,  loan
payments,  pre-authorized  debits,  etc.) or authorized us to make. Payments are
made by making deposits to the Operating Account. You may not at any time exceed
the  Credit  Limit.  We may,  without  notice to you,  return any debit from the
Operating  Account  that,  if paid,  would  result  in the  Credit  Limit  being
exceeded,  unless  you have made  prior  arrangements  with us. If we pay any of
these debits, you must repay us immediately the amount by which the Credit Limit
is exceeded.

1.20  Foreign Currency  Conversion.  If this Agreement includes foreign currency
Credits, then currency changes may affect whether either the Credit Limit of any
Credit or the Overall Credit Limit has been exceeded.

  (a)  See  section  1.4  for the  general  rules  on how  Default  Interest  is
calculated.

  (b) To determine the Overall Credit Limit,  all foreign  currency  amounts are
converted to U.S. dollars,  even if the Credit Limits of any particular  Credits
are quoted directly in a foreign currency (such as Canadian dollars).  No matter
how the  Credit  Limit of a  particular  Credit is quoted,  therefore,  currency
fluctuations can affect whether the Overall Credit Limit has been exceeded.  For
example,  if Credits X and Y have Credit  Limits of US$100,000  and  CDN$50,000,
respectively,  with an Overall  Credit  Limit of  US$135,000,  if Credit X is at
US$90,000 and Credit Y is at CDN$45,000,  Default  Interest will be charged only
if,  after  converting  the Cdn.  dollar  amount,  the Overall  Credit  Limit is
exceeded.

  (c) Whether the Credit Limit of a  particular  Credit has been  exceeded  will
depend on how the Credit Limit is quoted, as described below.

  (d) If the  Credit  Limit is quoted  as,  for  example,  the  Canadian  dollar
equivalent of a U.S. dollar amount,  daily exchange rate fluctuations may affect
whether that Credit Limit has been  exceeded.  If, on the other hand, the Credit
Limit is quoted in a foreign currency (for example,  directly in Cdn.  dollars),
whether that Credit Limit has been exceeded is  determined by reference  only to
the closing balance of that Credit in that currency.
<PAGE>

  (e) For example, assume an outstanding balance of a Credit on a particular day
of CDN$200,000.  If the Credit Limit is stated as "the Cdn. dollar equivalent of
US$140,000", then whether the Credit Limit of that Credit has been exceeded will
depend  on the  value  of  the  U.S.  dollar  on  that  day.  If the  conversion
calculations determine that the outstanding balance is under the Credit Limit, a
drop in the value of the U.S.  dollar  the next day  (without  any change in the
balance) may have the effect of putting that Credit over its Credit  Limit.  If,
on the other hand, the Credit Limit is stated as "CDN$200,000", the Credit Limit
is not  exceeded,  and a drop in the value of the  dollar  the next day will not
change that (although the Overall Credit Limit may be affected).

  (f)  Conversion  calculations  are done on the  closing  daily  balance of the
Credit.  The  conversion  factor  used is the  mid-point  between the buying and
selling rate offered by CIBC Inc. (or if such rates can not be  determined,  the
mid-point  between  such  rates  offered  by  CIBC)  for  that  currency  on the
conversion date.

1.21  Instalment Loans.  The following terms apply to each Instalment Loan.

  (a) Non-revolving loans. Unless otherwise stated in the Letter, any Instalment
Loan is  non-revolving.  This means that any principal  payment made permanently
reduces the  available  Loan Amount.  Any payment we receive is applied first to
overdue  interest,  then to current interest owing,  then to overdue  principal,
then to any fees and charges owing, and finally to current principal.

  (b) Floating Rate Instalment  Loans.  Floating Rate Instalment  Loans may have
either (i) blended  payments or (ii) payments of fixed principal  amounts,  plus
interest, as described below.

      (i) Blended  payments.  If you have a Floating  Rate Loan that has blended
      payments,  the amount of your monthly payment is fixed for the term of the
      loan,  but the  interest  rate  varies  with  changes in the Prime or U.S.
      Alternate  Base Rate (as the case may be). If the Prime or U.S.  Alternate
      Base Rate  during any month is lower than what the rate was at the outset,
      you may end up paying off the loan  before  the  scheduled  end date.  If,
      however,  the Prime or U.S. Alternate Base Rate is higher than what it was
      at the outset,  the amount of principal that is paid off is reduced.  As a
      result,  you may  end up  still  owing  principal  at the end of the  term
      because of these changes in the Prime or U.S. Alternate Base Rate.

      (ii) Payments of principal plus interest. If you have a Floating Rate Loan
      that has regular principal payments,  plus interest, the principal payment
      amount of your Loan is due on each payment  date  specified in the Letter.
      The interest  payment is also due on the same date, but it is debited from
      your  Operating  Account  one or two  banking  days  later.  Although  the
      principal  payment amount is fixed,  your interest payment will usually be
      different each month, for at least one and possibly more reasons,  namely:
      the  reducing  principal  balance of your loan,  the number of days in the
      month,  and changes to the Prime Rate or U.S.  Alternate Base Rate (as the
      case may be).

  (c)  Prepayment.  Unless  otherwise  agreed,  the  following  terms  apply  to
prepayment of any Instalment Loan:

      (i)  Floating  Rate  Instalment  Loans.  You may  prepay  all or part of a
      Floating Rate Instalment Loan (whether it is a Demand or a Committed Loan)
      at any time without notice or penalty.

      (ii) Fixed Rate  Instalment  Loans.  You may prepay all or part of a Fixed
      Rate Instalment Loan, on the following condition.  You must pay us, on the
      prepayment date, a prepayment fee equal to the interest rate  differential
      for the remainder of the term of the Loan, in accordance with the standard
      formula used by CIBC Inc. in these situations.

  (d) Demand of Fixed Rate  Demand  Instalment  Loans.  If you have a Fixed Rate
Demand  Instalment Loan and we make demand for payment,  you will owe us (i) all
outstanding  principal,  (ii)  interest,  (iii) any other  amount due under this
Agreement,  and  (iv) a  prepayment  fee.  The  prepayment  fee is  equal to the
interest  rate  differential  for the  remainder  of the  term of the  loan,  in
accordance with the standard formula used by CIBC Inc. in these situations.

1.22  Notice of Default.  You will promptly  notify us of the  occurrence of any
event that is an Event of  Default  (or any that would be an Event of Default if
the only thing required is either notice being given or time elapsing, or both).


                ARTICLE 1 - LIBO RATE PROVISIONS

1.1   Definitions.  In this  Agreement,  the following  terms have the following
meanings:

"LIBO Rate" for any LIBOR  Period means a rate of interest per year equal to the
rate at which we are prepared to offer, as at 11:00 a.m. (London,  England time)
on the second LIBOR Business Day before the start of that LIBOR Period, deposits
to leading banks in London,  England interbank  eurocurrency market in an amount
of U.S.  dollars  similar to the amount of the  applicable  LIBOR Loan and for a
deposit  period  comparable  to that LIBOR  Period;  except  that,  if we do not
receive  proper or timely  notice as required  below but we permit your request,
then the LIBOR Rate for such LIBOR Period means the rate of interest per year as
determined by us (in our absolute discretion) and offered to you and immediately
accepted by you.
<PAGE>

"LIBOR Business Day" means a Business Day on which U.S. dollar  transactions can
be carried out between  leading  banks in the interbank  eurocurrency  market in
London, England and between CIBC Inc. and other leading banks in New York City.

"LIBOR  Loan"  means a Fixed  Rate Loan in U.S.  dollars in whole  multiples  of
US$1,000,000 on which interest is calculated by reference to a LIBO Rate.

"LIBOR  Period"  means  the  period  selected  by you in  accordance  with  this
Agreement for computing interest from time to time on a LIBOR Loan.

1.2   Availability.  LIBOR  Loans  are  available  only in  whole  multiples  of
US$1,000,000 each, for terms of one to six months.

1.3   Required Notice.

  (a) You may draw down or roll over a LIBOR Loan,  or convert  another  type of
Credit under this  Agreement to a LIBOR Loan, or repay a LIBOR Loan, but only as
provided in this Article.  Any such action must be done on a LIBOR Business Day.
Also,  you  must  give  notice  (in  the  form  we  require)  to the  CIBC  Inc.
Branch/Centre before 10:00 a.m. (local time where the CIBC Inc. Branch/Centre is
located).  The notice must be given on the third LIBOR  Business  Day before the
requested date of drawdown, rollover, conversion or repayment.
You may roll over or  convert an  existing  LIBOR Loan only on the expiry of its
LIBOR Period.

  (b) If we do not receive  proper or timely notice as required by the preceding
paragraph,  we may (but we are not obliged to) decide what you are  permitted to
do for that LIBOR Loan. We may, on the other hand,  simply roll over an existing
LIBOR Loan at the end of its LIBOR  Period for a new LIBOR Loan with a new LIBOR
Period determined by us.

1.4   Maturity Limitation.  The expiry date of a LIBOR Period for any LIBOR Loan
may not (a) be after a scheduled or required  maturity or  termination  date for
that Credit or (b)  conflict,  in our opinion,  with any  scheduled or mandatory
repayment for that Credit.

1.5   Repayments.  You may only  repay all (but not part) of a LIBOR  Loan,  and
only on the last day of the LIBOR Period for that LIBOR Loan.

1.6   Interest  Calculation  and  Payment.  Interest  at a  LIBO  Rate  will  be
calculated on the daily balance of each LIBOR Loan for the actual number of days
elapsed,  on the basis of a 360 day year.  You will pay  interest  on each LIBOR
Loan in arrears at the end of each LIBOR  Period.  If a LIBOR  Period is greater
than three  months,  you will pay interest at the end of each three month period
during  that  LIBOR  Period,  except  that  overdue  interest  will  be  payable
immediately on demand. Overdue amounts in respect of a LIBOR Loan (including any
overdue  interest) may at our option be either converted to another type of loan
(if available) under any Credit or considered to be a LIBOR Loan for one or more
LIBOR Periods as we may determine.

1.7   Interest  Act.  Each nominal rate of interest  referenced  to a LIBO Rate,
expressed as an annual rate for purposes of the Interest Act  (Canada),  is that
rate  multiplied  by the actual number of days in the calendar year in which the
rate is to be ascertained, and divided by 360.

1.8   Lack of LIBO Rate.  At any time before the start of any LIBOR  Period,  we
might  determine  that (a) by  reason of  circumstances  affecting  the  London,
England interbank eurocurrency market generally,  adequate and fair means do not
exist for  determining  the LIBO Rate  applicable for that LIBOR Period,  or (b)
deposits in U.S. dollars are not in the ordinary course of business available to
CIBC Inc. in that market for deposit periods  comparable to that LIBOR Period in
a total amount similar to that LIBOR Loan bearing  interest at a rate no greater
than the LIBO Rate  applicable to that LIBOR Loan. If we do, then from and after
that date, you may not roll over any existing LIBOR Loan at the end of its LIBOR
Period, or obtain any new LIBOR Loan. Our determination of any events under this
paragraph will be conclusive.

1.9   Illegality.  If at any time we  determine  in good  faith  that any  legal
requirement  or any  official  directive  or request  (whether or not having the
force of law) by a central  bank or other  governmental  authority  will make it
unlawful or impossible for us to make,  maintain or fund any LIBOR Loan, we will
notify you accordingly. Upon receiving such a notice, you will either (a) on the
last day of the LIBOR  Period of any LIBOR Loan,  if we can continue to maintain
that loan, or (b) immediately,  if we cannot legally maintain that loan,

  (1) pay us in  full the then  outstanding  principal amount of each such LIBOR
Loan, together with all accrued interest, or

  (2) convert that loan into another type of loan allowed under this Agreement.

For clarification,  upon a payment or conversion of a LIBOR Loan made under this
section  in the  middle  of its LIBOR  Period,  you will  immediately  on demand
compensate us as provided elsewhere in this Agreement.  Our determination of any
matters under this paragraph will be conclusive.

Rate Loan includes a LIBOR Loan.

"Floating Rate Instalment  Loan" means an Instalment Loan that is either a Prime

"Normal  Course Lien" means a Lien that (a) arises by operation of law or in the
ordinary  course of  business as a result of owning any such asset (but does not

affect the value of the asset or its use in the business.

"Operating  Account"  means the account that you normally use for the day-to-day
cash needs of your  business,  and may be either or both of a U.S.  dollar and a

as declared by CIBC Inc.  from time to time to be its base rate for U.S.  dollar
commercial  demand loans made by CIBC Inc. in the United States of America,  and

           in the United States; and

      (b)  the  "Federal  Funds Rate" plus 0.5%,  where the  Federal  Funds Rate
           means,  for any  particular  day, the  variable  rate of interest per
           year,  calculated  on the basis of a year of 360  days,  equal to the
           weighted  average of rates on overnight  federal  funds  transactions
           with members of the Federal  Reserve System arranged by Federal Funds
           brokers  as  released  on the  next  succeeding  business  day by the
           Federal Reserve Bank of New York;
Neither the U.S.  Alternate  Base Rate nor any component  thereof is necessarily
intended to be the lowest rate of interest determined by CIBC Inc. in connection
with extensions of credit.

                              its  operating  line  facility  pursuant  to  CIBC
                              Inc.'s credit agreement dated on or about the date
                              hereof, as amended and replaced from time to time,
                              (the "CIBC Inc. Credit Agreement").

                              make any material  acquisitions  without our prior
                              written  consent,  except,  provided  no  Event of

                              acquisition during the fiscal quarter  immediately
                              succeeding  the fiscal  quarter  within  which the
                              acquisition  was made  (calculated on the basis of
                              the  financial  statements  of the  Guarantor on a
                              consolidated   basis   submitted  for  the  fiscal
                              quarter of the Guarantor immediately preceding the

                              not been (in our  reasonable  opinion) a Change of
                              Control of your company or the Guarantor:

                              (a) the Guarantor, or any of its subsidiaries, may
                              make an  acquisition  without  our  prior  written
                              consent  if the  purchase  price in respect of the
                              proposed   acquisition   does   not   exceed   the
                              Applicable Limit referred to below; and

                              (b)  if  the  purchase  price  in  respect  of the
                              proposed  acquisition exceeds the Applicable Limit
                              referred to below,  the  Guarantor,  or any of its
                              subsidiaries,  may nevertheless  make the proposed
                              acquisition   if  you   first   provide   proforma
                              financial statements to us which take into account
                              the  effect of the  proposed  acquisition  and all
                              debt incurred or assumed in connection  therewith,
                              and   which   demonstrate   compliance   with  all
                              financial covenants/requirements set forth herein,
                              both before and after the proposed acquisition.

                              For the purposes  hereof,  the "Applicable  Limit"
                              means U.S.$80,000,000 unless the Debt to Effective
                              Equity Ratio of the  Guarantor  on a  consolidated
                              basis (exclusive of the acquisition)  exceeds 1:1,
                              in  which  case  the   "Applicable   Limit"  means
                              U.S.$40,000,000.

                              Restriction on Divestments:  Neither the Guarantor
                              nor any of its  subsidiaries  (including you) will
                              make any material business divestment,  other than
                              for cash,  without our prior written consent.  The
                              cash proceeds from the material divestment will be
                              used  in  the  first   instance   to  retire   any
                              outstanding   borrowings/indebtedness   under  the
                              credit  facilities  established  hereunder  which,
                              however,  may be readvanced or incurred subject to
                              your  continued  compliance  with all of the terms
                              and conditions of the credit  facilities  provided
                              for hereunder.

                              will  provide  us with a copy  of the  Guarantor's
                              Form 10-K as of that year-end, which is to include
                              a copy  of the  Guarantor's  audited  consolidated
                              year-end financial statements.

  Capital Adequacy, Etc.      change  in or in  the  interpretation  of,  or any
                              change in its application to us of, any law or any
                              regulation or guideline issued by any central bank
                              or other  governmental  authority  (whether or not
                              having  the  force  of  law),   including  without
                              limitation   any   reserve  or   special   deposit
                              requirement  or any  tax  (other  than  tax on our
                              general  income) or any capital  requirement,  has
                              (due to our  compliance)  the effect,  directly or
                              indirectly,  of (i)  increasing  the cost to us of
                              performing our obligations  hereunder or under any
                              B/A or L/C; (ii)  reducing any amount  received or
                              receivable by us hereunder or our effective return
                              hereunder or on our capital;  or (iii)  causing us
                              to make any  payment or to forgo any return  based
                              on  any  amount   received  or  receivable  by  us
                              hereunder  or in respect  of any B/A or L/C;  then
                              upon  demand  from  time to time you will pay such
                              amount as shall  compensate  us for any such cost,
                              reduction,  payment  or forgone  return.  You will
                              further indemnify us for all out-of-pocket  costs,
                              losses and expenses  incurred by us in  connection
                              with any B/A or L/C and agree that we will have no
                              liability  to you for any reason in respect of any
                              availment  other  than  on  account  of our  gross
                              negligence or wilful  misconduct.  Any certificate
                              of  CIBC  in  respect  of the  foregoing  will  be
                              conclusive  and  binding  upon  you,   except  for
                              manifest  error,  provided that we shall determine
                              the  amounts  owing to us in good faith  using any
                              reasonable averaging and attribution methods.




  Obligations re L/Cs if      You will pay to us on demand all of our contingent

                              which  is  the   subject   matter  of  any  order,
                              judgment,  injunction or other such  determination
                              restricting  payment by us under and in accordance
                              with such L/C or  extending  our  liability  under
                              such L/C beyond the expiration date stated therein
                              (an "Order").  We agree that we will, with respect
                              to each such L/C, upon the later of:


                              (a) the earlier  of: (i) the date on which  either
                              the original  counterpart  of such L/C is returned
                              to us for  cancellation  or we are released by the
                              beneficiary   from  any  further   obligations  in
                              respect of such L/C;  and, (ii) the expiry of such
                              L/C; and

                              (b) the date on which any final order, judgment or
                              other  such  determination  has been  rendered  or
                              issued either terminating the applicable Order, or
                              permanently  enjoining  us from paying  under such
                              L/C;
<PAGE>

                              pay to you an  amount  equal to any  excess of the
                              amount  received by us hereunder in respect of our
                              contingent liability under such L/C (the "Received
                              Amount")  over the  total of  amounts  applied  to
                              reimburse us for amounts paid by us under such L/C
                              (CIBC  having  the  right to so  appropriate  such
                              funds),   together  with  an   additional   amount
                              computed  by applying to the amount of such excess
                              from time to time a per annum rate equal to 3% per
                              year  less than the Prime  Rate.  Such  additional
                              amount shall be calculated daily on the basis of a
                              calendar  year  for  the  actual  number  of  days
                              elapsed from and  including the date of payment to
                              us of the Received  Amount to (but not  including)
                              the date of return to you of the excess.

                              agreeable terms.

6326-95/06                      Schedule - Standard Credit
WP51CRED)
                               ARTICLE 1 - GENERAL

1.1   Interest  Rate.  You will pay interest on each Credit at nominal rates per
year equal to:

  (a) for  amounts  above  the Credit Limit of a Credit or a part of a Credit or
for amounts that are not paid when due, the Default Interest Rate, and

  (b) for any other amounts, the rate specified in this Agreement.

1.2   Variable  interest.  Each  variable  interest rate provided for under this
Agreement will change automatically,  without notice, whenever the Prime Rate or
the U.S. Base Rate, as the case may be, changes.

1.3   Payment of interest.  Interest is  calculated  on the daily balance of the
Credit  at the end of  each  day.  Interest  is due  once a  month,  unless  the
Agreement states otherwise.  Unless you have made other arrangements with us, we
will  automatically  debit your Operating Account for interest amounts owing. If
your Operating  Account is in overdraft and you do not deposit to the account an
amount  equal to the  monthly  interest  payment,  the effect is that we will be
charging  interest on overdue interest (which is known as  compounding).  Unpaid
interest  continues to compound whether or not we have demanded payment from you
or started a legal action, or get judgment, against you.

1.4   Default Interest.  To determine whether Default Interest is to be charged,
the following rules apply:

  (a) Default  Interest  will be charged on the amount  that  exceeds the Credit
Limit of any particular Credit.

  (b) If there are several parts of a Credit,  Default  Interest will be charged
if the Credit Limit of a particular part is exceeded. For example, if Credit A's
limit is  $250,000,  and the limit of one part is $100,000 and the limit of that
part is exceeded by $25,000,  Default  Interest  will be charged on that $25,000
excess,  even if the  total  amount  outstanding  under  Credit  A is less  than
$250,000.

1.5   Fees.  You will pay CIBC's fees for each Credit as outlined in the Letter.
You will also reimburse us for all reasonable  fees  (including  legal fees) and
out-of-pocket  expenses  incurred in registering any security,  and in enforcing
our rights under this  Agreement or any security.  We will  automatically  debit
your Operating Account for fee amounts owing.

1.6   Our rights re demand Credits. At CIBC, we believe that the banker-customer
relationship  is based on mutual  trust and respect.  It is important  for us to
know all the relevant  information  (whether  good or bad) about your  business.
CIBC is itself a business.  Managing risks and monitoring our customers' ability
to repay is  critical  to us. We can only  continue to lend when we feel that we
are likely to be repaid.  As a result, if you do something that jeopardizes that
relationship,  or if we no longer  feel that you are likely to repay all amounts
borrowed,  we may have to act.  We may decide to act,  for  example,  because of
something you have done,  information we receive about your business, or changes
to the economy that affect your business. Some of the actions that we may decide
to take include requiring you to give us more financial information, negotiating
a change in the interest rate or fees,  or asking you to get further  accounting
assistance, put more cash into the business, provide more security, or produce a
satisfactory  business plan. It is important to us that your business  succeeds.
We  may,  however,  at  our  discretion,   demand  immediate  repayment  of  any
outstanding  amounts under any demand  Credit.  We may also, at any time and for
any cause,  cancel  the  unused  portion  of any  demand  Credit.  Under  normal
circumstances,  however,  we will  give  you 30  days'  notice  of any of  these
actions.

1.7   Payments.  If any payment is due on a day other than a Business  Day, then
the payment is due on the next Business Day.

1.8   Applying money received. If you have not made payments as required by this
Agreement,  or if you have failed to satisfy any term of this  Agreement (or any
other agreement you have that relates to this Agreement),  or at any time before
default  but after we have given you  appropriate  notice,  we may decide how to
apply any money that we receive.  This means that we may choose  which Credit to
apply the money against,  or what mix of principal,  interest,  fees and overdue
amounts within any Credit will be paid.

1.9   Information requirements.  We may from time to time reasonably require you
to provide further  information about your business.  We may require information
from you to be in a form acceptable to us. We will use your  information only in
connection with the credits and will keep it confidential  unless required to be
disclosed by law or court order.

1.10  Insurance. You will keep all your business assets and property insured (to
the full  insurable  value)  against  loss or damage by fire and all other risks
usual for  property  such as yours (plus for any other  risks we may  reasonably
require). If we ask, you will give us either the policies themselves or adequate
evidence of their existence. If your insurance coverage for any reason stops, we
may (but do not have to) insure the property.  We will automatically  debit your
Operating Account for these amounts.  Finally, you will notify us immediately of
any loss or damage to the property.
<PAGE>

1.11  Environmental.  You will carry on your business,  and maintain your assets
and  property,  in  accordance  with  all  applicable   environmental  laws  and
regulations.  If (a) there is any  release,  deposit,  discharge  or disposal of
pollutants of any sort  (collectively,  a "Discharge") in connection with either
your business or your property, and we pay any fines or for any clean-up, or (b)
we suffer any loss or damage as a result of any  Discharge,  you will  reimburse
CIBC,  its  directors,  officers,  employees  and agents for any and all losses,
damages,  fines,  costs and other amounts (including amounts spent preparing any
necessary environmental  assessment or other reports, or defending any lawsuits)
that  result.  If we ask,  you  will  defend  any  lawsuits,  investigations  or
prosecutions brought against CIBC or any of its directors,  officers,  employees
and agents in connection  with any Discharge.  Your  obligation to us under this
section continues even after all Credits have been repaid and this Agreement has
terminated.

1.12  Consent to release  information.  We may from time to time give any credit
information  about you to, or receive such  information  from, (a) any financial
institution,  credit reporting agency,  rating agency or credit bureau,  (b) any
person,  firm or corporation with whom you may have or propose to have financial
dealings,  and (c) any  person,  firm or  corporation  in  connection  with  any
dealings  you have or  propose  to have with us.  You agree that we may use that
information to establish and maintain your relationship with us and to offer any
services as permitted  by law,  including  services and products  offered by our
subsidiaries when it is considered that this may be suitable to you.

1.13  Our  pricing  policy:  Fees,  interest  rates and other  charges  for your
banking  arrangements are dependent upon each other. If you decide to cancel any
of these  arrangements,  you will have to pay us any  increased  or added  fees,
interest  rates and charges we determine  and notify you of. These  increased or
added amounts are effective from the date of the changes that you make.

1.14  Proof of debt. This Agreement provides the proof, between CIBC and you, of
the credit made available to you. There may be times when the type of Credit you
have  requires you to sign  additional  documents.  Throughout  the time that we
provide  you credit  under this  Agreement,  our loan  accounting  records  will
provide  complete  proof of all terms and  conditions  of your  credit  (such as
principal loan balances, interest calculations, and payment dates).

1.15  Renewals of this Agreement.  This Agreement will remain in effect for your
Credits for as long as they  remain  unchanged.  We have shown a Next  Scheduled
Review Date in the Letter. If there are no changes to the Credits this Agreement
will continue to apply, and you will not need to sign anything further. If there
are any changes, we will provide you with either an amending agreement, or a new
replacement Letter, for you to sign.

1.16  Confidentiality:  The terms of this Agreement are confidential between you
and CIBC. You therefore  agree not to disclose the contents of this Agreement to
anyone  except  your  professional  advisors  or (as  required  by  law)  to any
regulatory or governmental body.

1.17  Pre-conditions.  You  may  use  the  Credits  granted  to you  under  this
Agreement only if:

  (a) we have received properly signed copies of all  documentation  that we may
reasonably  require  and which we have  provided to you in  connection  with the
operation of your accounts and your ability to borrow;
  (b)  all the  required  security  has  been  received  and  registered  to our
satisfaction;
  (c) any special  provisions  or  conditions  set forth in the Letter have been
complied with; and
  (d) if applicable,  you have given us the required number of days notice for a
drawing under a Credit.

1.18  Notices.  We may give you any  notice  in person  or by  telephone,  or by
letter that is sent either by fax or by mail.

1.19  Use of the Operating  Line. You will use your Operating Line only for your
business  operating  cash  needs.  You are  responsible  for all debits from the
Operating  Account  that you  have  either  initiated  (such  as  cheques,  loan
payments,  pre-authorized  debits,  etc.) or authorized us to make. Payments are
made by making deposits to the Operating Account. You may not at any time exceed
the  Credit  Limit.  We may,  without  notice to you,  return any debit from the
Operating  Account  that,  if paid,  would  result  in the  Credit  Limit  being
exceeded,  unless  you have made  prior  arrangements  with us. If we pay any of
these debits, you must repay us immediately the amount by which the Credit Limit
is exceeded.

1.20  Foreign Currency  Conversion.  If this Agreement includes foreign currency
Credits, then currency changes may affect whether either the Credit Limit of any
Credit or the Overall Credit Limit has been exceeded.

  (a) See  section   1.4  for the  general  rules  on how  Default  Interest  is
calculated.

  (b) To determine the Overall Credit Limit,  all foreign  currency  amounts are
converted  to  Canadian  dollars,  even if the Credit  Limits of any  particular
Credits are quoted  directly in a foreign  currency (such as U.S.  dollars).  No
matter  how the  Credit  Limit of a  particular  Credit  is  quoted,  therefore,
currency  fluctuations  can affect  whether  the Overall  Credit  Limit has been
exceeded.  For example,  if Credits X and Y have Credit  Limits of C$100,000 and
US$50,000,  respectively, with an Overall Credit Limit of C$175,000, if Credit X
is at C$90,000 and Credit Y is at  US$45,000,  Default  Interest will be charged
only if, after  converting  the US dollar  amount,  the Overall  Credit Limit is
exceeded.

  (c) Whether the Credit Limit of a  particular  Credit has been  exceeded  will
depend on how the Credit Limit is quoted, as described below.
<PAGE>

  (d) If the Credit Limit is quoted as, for example,  the U.S. dollar equivalent
of a Canadian dollar amount, daily exchange rate fluctuations may affect whether
that Credit Limit has been exceeded.  If, on the other hand, the Credit Limit is
quoted in a foreign currency (for example, directly in US dollars), whether that
Credit Limit has been exceeded is  determined  by reference  only to the closing
balance of that Credit in that currency.

  (e) For example, assume an outstanding balance of a Credit on a particular day
of  US$200,000.  If the Credit Limit is stated as "the US dollar  equivalent  of
C$275,000",  then whether the Credit Limit of that Credit has been exceeded will
depend  on the value of the  Canadian  dollar  on that  day.  If the  conversion
calculations determine that the outstanding balance is under the Credit Limit, a
drop in the value of the Canadian dollar the next day (without any change in the
balance) may have the effect of putting that Credit over its Credit  Limit.  If,
on the other hand, the Credit Limit is stated as "US$200,000",  the Credit Limit
is not  exceeded,  and a drop in the value of the  dollar  the next day will not
change that (although the Overall Credit Limit may be affected).

  (f) Conversion  calculations  are done on  the  closing  daily  balance of the
Credit.  The  conversion  factor  used is the  mid-point  between the buying and
selling rate offered by CIBC for that currency on the conversion date.

1.21  Instalment Loans.  The following terms apply to each Instalment Loan.

  (a) Non-revolving loans. Unless otherwise stated in the Letter, any Instalment
Loan is  non-revolving.  This means that any principal  payment made permanently
reduces the  available  Loan Amount.  Any payment we receive is applied first to
overdue  interest,  then to current interest owing,  then to overdue  principal,
then to any fees and charges owing, and finally to current principal.

  (b) Floating Rate Instalment  Loans.  Floating Rate Instalment  Loans may have
either (i) blended  payments or (ii) payments of fixed principal  amounts,  plus
interest, as described below.

      (i) Blended  payments.  If you have a Floating  Rate Loan that has blended
      payments,  the amount of your monthly payment is fixed for the term of the
      loan,  but the interest rate varies with changes in the Prime or U.S. Base
      Rate (as the case may be). If the Prime or U.S. Base Rate during any month
      is lower than what the rate was at the  outset,  you may end up paying off
      the loan before the scheduled  end date.  If,  however,  the Prime or U.S.
      Base  Rate  is  higher  than  what it was at the  outset,  the  amount  of
      principal that is paid off is reduced.  As a result,  you may end up still
      owing  principal  at the end of the term  because of these  changes in the
      Prime or U.S. Base Rate.

      (ii) Payments of principal plus interest. If you have a Floating Rate Loan
      that has regular principal payments,  plus interest, the principal payment
      amount of your Loan is due on each payment  date  specified in the Letter.
      The interest  payment is also due on the same date, but it is debited from
      your  Operating  Account  one or two  banking  days  later.  Although  the
      principal  payment amount is fixed,  your interest payment will usually be
      different each month, for at least one and possibly more reasons,  namely:
      the  reducing  principal  balance of your loan,  the number of days in the
      month,  and  changes to the Prime Rate or U.S.  Base Rate (as the case may
      be).

  (c) Prepayment.  Unless   otherwise  agreed,  the  following  terms  apply  to
prepayment of any Instalment Loan:

      (i)  Floating  Rate  Instalment  Loans.  You may  prepay  all or part of a
      Floating Rate Instalment Loan (whether it is a Demand or a Committed Loan)
      at any time without notice or penalty.

      (ii) Fixed Rate  Instalment  Loans.  You may prepay all or part of a Fixed
      Rate Instalment Loan, on the following condition.  You must pay us, on the
      prepayment date, a prepayment fee equal to the interest rate  differential
      for the remainder of the term of the Loan, in accordance with the standard
      formula used by CIBC in these situations.

  (d) Demand of Fixed Rate  Demand  Instalment  Loans.  If you have a Fixed Rate
Demand  Instalment Loan and we make demand for payment,  you will owe us (i) all
outstanding  principal,  (ii)  interest,  (iii) any other  amount due under this
Agreement,  and  (iv) a  prepayment  fee.  The  prepayment  fee is  equal to the
interest  rate  differential  for the  remainder  of the  term of the  loan,  in
accordance with the standard formula used by CIBC in these situations.

1.22  Notice of Default.  You will promptly  notify us of the  occurrence of any
event that is an Event of  Default  (or any that would be an Event of Default if
the only thing required is either notice being given or time elapsing, or both).

                        ARTICLE 1 - BANKERS' ACCEPTANCES

1.1   Definitions.  In this  Article,  the  following  terms have the  following
meanings:

"Bankers'  Acceptance"  or "B/A"  means a  Canadian  dollar  Draft  that we have
accepted under this Agreement.

"Commerce  Acceptance  Rate" means the variable  reference  rate that we declare
from time to time as our stamping or acceptance fee for Drafts accepted by us.

"Draft" means,  at any time, a blank bill of exchange  within the meaning of the
Bills of Exchange Act drawn by the Customer on us (in  satisfactory  form),  but
before we have accepted it.

1.2   Availability. B/As are available only with terms to maturity of between 30
and 180 days.
<PAGE>

1.3   Minimum issue amount.  You will present Drafts for acceptance in a minimum
amount of $1 million.  We can change this minimum amount at any time by 30 days'
prior written notice.

1.4   Required  Notice.  You may either  obtain a new  advance  by issuing a B/A
stamped by CIBC  (including a rollover of an existing B/A) or you may convert an
amount  outstanding  under another  Credit to issuance of a B/A on the following
terms.  You  must  give us  notice  (in the  form we  require,  including,  when
applicable,  the date of acceptance,  the amount and the maturity date).  Notice
must be given by 10:00 a.m. (local time where the CIBC Branch/Centre is located)
on the Business Day prior to the requested date of issuance.  You must also give
us any other notice required by the Letter.

1.5   Special Conditions.

  (a) Draft  Conditions.  You will  deliver to us the Drafts that you want us to
issue.  Each Draft must (i) be in a whole  multiple of C$100,000,  (ii) be dated
the date of  delivery  (which  will be the same date as the  requested  date you
notified us);  (iii) mature on a Business Day; and (iv) be presented to the CIBC
Branch/Centre  for acceptance by 12:00 noon on the date of delivery  (unless you
have made prior arrangements in writing with us).

  (b)  Maturity  Limitation.  The maturity  date of a Draft  submitted to us for
acceptance  may not (i) be after a  scheduled  or  mandatory  final  maturity or
termination  date for that Credit or (ii)  conflict,  in our  opinion,  with any
scheduled or mandatory repayment for that Credit.

(c)  Conversion-To-Loan  Limitation.  You may  only  convert  a B/A  into a loan
otherwise allowed under this Agreement if the total of "A" plus "B" is less than
Prime Rate existing on that maturity date, where:

      "A" is the annual discount rate quoted at 9:30 a.m.  (Toronto time) by the
      Toronto  office of Wood Gundy Inc. as the discount  rate at which it would
      purchase a bankers' acceptance issued by CIBC having a term to maturity of
      30 days, and

      "B" is the  annual  stamping  or  acceptance  rate  applicable  to a Draft
      accepted by us under this Agreement, as determined on the maturity date of
      that B/A.

In making these calculations, each of "A" and "B" is expressed as a percentage.

1.6   Stamping Fee. When we accept a Draft under this Agreement, you will pay us
a  stamping  fee,  on the date of  acceptance,  in the  amount as set out in the
Letter. The stamping fee will be calculated on the face amount of that Draft for
the number of days to maturity based on a 365 day year.

1.7   Reimbursement.  B/As  are negotiable  instruments  that are  purchased  in
financial  markets at a discount.  Market  forces  determine  what the  discount
amount for B/As is at any  particular  time.  At  maturity,  the holder of a B/A
redeems  it from  CIBC.  We then pay the  holder  the  face  amount.  You  will,
therefore,  reimburse  us at the  maturity  date for the face amount of all B/As
that we have  accepted  for you,  unless you  convert  those  amounts to another
Credit  (assuming all proper notice has been given).  If you do not reimburse us
or convert those amounts to another  Credit,  we may convert them to any type of
loan (if available) under any Credit.

1.8   Signatures and Safekeeping. All Drafts must either be signed by a properly
authorized signing officer or bear a mechanically reproduced facsimile signature
of that officer (subject to any prior written  arrangements with us). Each Draft
and B/A bearing a facsimile  signature of that officer will be as binding on you
as if it had  been  manually  signed  by that  officer.  This  applies  even for
individuals  who may no longer be  authorized  or otherwise be an officer at any
time.  You will  compensate us for any loss or expense  relating to any Draft or
B/A that we deal with  under  this  Agreement.  We need only  exercise  the same
degree  of  care in  safekeeping  executed  Drafts  delivered  to us for  future
acceptance as if they were CIBC's property and we were keeping them at the place
at which they are to be held.

1.9   Credit  Cancellation.  If your B/A Credit is terminated for any reason, we
may require you to pay us  immediately on demand the  appropriate  reimbursement
amount for each B/A then outstanding. We will calculate the reimbursement amount
in accordance with standard  practice in the banking  industry in Canada.  After
making this  payment,  (a) you will have no further  liability for that B/A, and
(b) we will (i) become the sole party liable under the B/A, and (ii)  compensate
you if you have to pay anyone else under that B/A.

1.10  Waiver. You will not claim any days of grace for the payment of a B/A. You
waive any defence to payment which might otherwise exist if for any reason a B/A
is held by us in our own right at its maturity.

1.11  Obligations   Absolute.   Your   obligations   for  Drafts  and  B/As  are
unconditional  and irrevocable.  You will perform your  obligations  strictly in
accordance with the provisions of this Agreement including,  among other things,
(a) any lack of validity or  enforceability  of a Draft accepted by us as a B/A,
and (b) the existence of a claim, set-off,  defence or other right which you may
have against the holder of a B/A, CIBC or another person.

<PAGE>

                        ARTICLE 2 - LIBO RATE PROVISIONS

2.1   Definitions.  In this Agreement,  the  following  terms have the following
meanings:

"LIBO Rate" for any LIBOR  Period means a rate of interest per year equal to the
rate at which we are prepared to offer, as at 11:00 a.m. (London,  England time)
on the second LIBOR Business Day before the start of that LIBOR Period, deposits
to leading banks in London,  England interbank  eurocurrency market in an amount
of U.S.  dollars  similar to the amount of the  applicable  LIBOR Loan and for a
deposit  period  comparable  to that LIBOR  Period;  except  that,  if we do not
receive  proper or timely  notice as required  below but we permit your request,
then the LIBOR Rate for such LIBOR Period means the rate of interest per year as
determined by us (in our absolute discretion) and offered to you and immediately
accepted by you.

"LIBOR Business Day" means a Business Day on which U.S. dollar  transactions can
be carried out between  leading  banks in the interbank  eurocurrency  market in
London, England and between CIBC and other leading banks in New York City.

"LIBOR  Loan"  means a Fixed  Rate Loan in U.S.  dollars in whole  multiples  of
US$1,000,000 on which interest is calculated by reference to a LIBO Rate.

"LIBOR  Period"  means  the  period  selected  by you in  accordance  with  this
Agreement for computing interest from time to time on a LIBOR Loan.

2.2   Availability.  LIBOR  Loans  are  available  only in  whole  multiples  of
US$1,000,000 each, for terms of one to six months.

2.3   Required Notice.

  (a) You may draw down or roll over a LIBOR Loan,  or convert  another  type of
Credit under this  Agreement to a LIBOR Loan, or repay a LIBOR Loan, but only as
provided in this Article.  Any such action must be done on a LIBOR Business Day.
Also,  you must give notice (in the form we  require) to the CIBC  Branch/Centre
before 10:00 a.m.  (local time where the CIBC  Branch/Centre  is  located).  The
notice must be given on the third LIBOR  Business Day before the requested  date
of drawdown, rollover,  conversion or repayment. You may roll over or convert an
existing LIBOR Loan only on the expiry of its LIBOR Period.

  (b) If we do not receive  proper or timely notice as required by the preceding
paragraph,  we may (but we are not obliged to) decide what you are  permitted to
do for that LIBOR Loan. We may, on the other hand,  simply roll over an existing
LIBOR Loan at the end of its LIBOR  Period for a new LIBOR Loan with a new LIBOR
Period determined by us.

2.4   Maturity Limitation.  The expiry date of a LIBOR Period for any LIBOR Loan
may not (a) be after a scheduled or required  maturity or  termination  date for
that Credit or (b)  conflict,  in our opinion,  with any  scheduled or mandatory
repayment for that Credit.

2.5   Repayments.  You may only  repay all (but not part) of a LIBOR  Loan,  and
only on the last day of the LIBOR Period for that LIBOR Loan.

2.6   Interest  Calculation  and  Payment.  Interest  at a  LIBO  Rate  will  be
calculated on the daily balance of each LIBOR Loan for the actual number of days
elapsed,  on the basis of a 360 day year.  You will pay  interest  on each LIBOR
Loan in arrears at the end of each LIBOR  Period.  If a LIBOR  Period is greater
than three  months,  you will pay interest at the end of each three month period
during  that  LIBOR  Period,  except  that  overdue  interest  will  be  payable
immediately on demand. Overdue amounts in respect of a LIBOR Loan (including any
overdue  interest) may at our option be either converted to another type of loan
(if available) under any Credit or considered to be a LIBOR Loan for one or more
LIBOR Periods as we may determine.

2.7   Interest  Act.  Each nominal rate of interest  referenced  to a LIBO Rate,
expressed as an annual rate for purposes of the Interest Act  (Canada),  is that
rate  multiplied  by the actual number of days in the calendar year in which the
rate is to be ascertained, and divided by 360.

2.8   Lack of LIBO Rate.  At any time before the start of any LIBOR  Period,  we
might  determine  that (a) by  reason of  circumstances  affecting  the  London,
England interbank eurocurrency market generally,  adequate and fair means do not
exist for  determining  the LIBO Rate  applicable for that LIBOR Period,  or (b)
deposits in U.S. dollars are not in the ordinary course of business available to
CIBC in that market for deposit  periods  comparable  to that LIBOR  Period in a
total amount  similar to that LIBOR Loan  bearing  interest at a rate no greater
than the LIBO Rate  applicable to that LIBOR Loan. If we do, then from and after
that date, you may not roll over any existing LIBOR Loan at the end of its LIBOR
Period, or obtain any new LIBOR Loan. Our determination of any events under this
paragraph will be conclusive.

2.9   Illegality.  If at any time we  determine  in good  faith  that any  legal
requirement  or any  official  directive  or request  (whether or not having the
force of law) by a central  bank or other  governmental  authority  will make it
unlawful or impossible for us to make,  maintain or fund any LIBOR Loan, we will
notify you accordingly. Upon receiving such a notice, you will either (a) on the
last day of the LIBOR  Period of any LIBOR Loan,  if we can continue to maintain
that loan, or (b) immediately,  if we cannot legally maintain that loan,

  (1) pay us in full the then  outstanding  principal  amount of each such LIBOR
Loan, together with all accrued interest, or
<PAGE>

  (2) convert that loan into another type of loan allowed under this Agreement.

For clarification,  upon a payment or conversion of a LIBOR Loan made under this
section  in the  middle  of its LIBOR  Period,  you will  immediately  on demand
compensate us as provided elsewhere in this Agreement.  Our determination of any
matters under this paragraph will be conclusive.

Prime Rate Loan or a Base Rate Loan.

"Instalment  Loan" means a loan that is repayable either in fixed instalments of

ordinary  course of  business as a result of owning any such asset (but does not
