                              PROSPECTUS SUMMARY


     The following summary is qualified in its entirety by the more detailed
information and the financial statements and notes appearing elsewhere in this
prospectus. Unless otherwise indicated, information in this prospectus assumes
that the underwriters will not exercise their over-allotment option. This
prospectus also assumes the redemption of all outstanding shares of Class A
Redeemable Preferred Stock and the conversion into common stock of all
outstanding shares of Junior Convertible Preferred Stock, Class B Convertible
Preferred Stock and Class C Convertible Preferred Stock upon the closing of

                                     Maker

     Maker is a semiconductor company that develops and markets
high-performance programmable processors, development tools and application
software for use in communications systems equipment. Our processors are
optimized for processing and switching data, voice and video in high-capacity
networks. Our processors perform complex tasks such as managing traffic and
internetworking within and between networks that are based on advanced
networking technologies, such as Asynchronous Transfer Mode (ATM) and Internet
Protocol (IP) packet switching. We have over 50 design wins with over 30
telecommunications and network equipment vendors, of which over 15 were in
production during the first quarter of 1999. Our top five customers in 1998
were Ascend, Cisco, Fore, Lucent and Nortel.

     The explosive growth of the Internet, the increase in demand for higher
speed interconnectivity between wide area networks and local area networks and
the increased use of technology that enables networks to be accessed remotely
are creating a rapidly expanding and increasingly complex communications
network infrastructure. Network service providers are adding capacity and
offering enhanced services that require new equipment with much higher
performance and the flexibility to support rapidly evolving industry standards.
This equipment traditionally has incorporated fixed-function integrated
circuits, called ASICs and ASSPs, which provide the requisite level of
performance but cannot adapt to changing market requirements and require
lengthy development cycles, or general purpose processors, called RISC and CISC
processors, that are programmable but have limited performance.

     Our communications processors are optimized for networks based on advanced
technologies and have performance levels equivalent to fixed-function
integrated circuits and superior to general purpose processors. Unlike
fixed-function integrated circuits, our processors provide functional
flexibility which enables communications systems vendors to:

     o quickly adapt to rapidly evolving standards and market requirements;
     o improve time-to-market of new and improved products;
     o add features to create product differentiation; and
     o utilize a common architecture across product lines.

     We focus on emerging high growth segments of communications systems
equipment markets that require sophisticated functionality in managing network
traffic and internetworking. Our MXT3010 Cell Processor and related software
target the high-performance segment of the Asynchronous Transfer Mode equipment
market. We believe that we have become a leading provider in the market for
Segmentation and Reassembly (SAR) devices that operate at OC-12 (622 Mbps)
rates, an industry-standard measurement of speed. We recently announced the
introduction of our MXT4000 Traffic Stream Processor family and related
software to address the opportunity for Internet Protocol-based services in
addition to Asynchronous Transfer Mode. These devices will support
sophisticated traffic management and internetworking at rates up to OC-48 (2.5
Gbps), or four times faster than OC-12/
622Mbps. We offer complete production-tested application software that runs on
our processor families. Customers may use this software as is, customize it or
write their own custom software to address specific applications using our
development tools.

                                 RISK FACTORS

     An investment in our common stock is risky. You should carefully consider
the following risks, as well as the other information contained in this
prospectus.


We Have a Limited Operating History and Have Not Had a Profitable Quarter

   
     We were incorporated in 1994 and did not begin shipping products in volume
until 1997. We have a limited operating history upon which investors may
evaluate us and our prospects. Although our revenues have increased in recent
years, and revenues for recent quarters have exceeded revenues for the same
quarter for the prior year, we have not yet completed a profitable quarter. In
1998, we incurred a net loss of $3.8 million. We intend to increase our
operating expenses significantly in 1999, particularly in research and
development and sales and marketing. Our operating results will be adversely
affected if our revenues do not increase significantly over the same period. We
cannot assure you that we will be able to achieve profitability on a quarterly
or an annual basis.


We Experience Fluctuations in Our Operating Results Due to a Number of
   Frequently Changing Business Conditions
    

     We have experienced fluctuations in our operating results in the past and
we expect such fluctuations to occur in the future due to a variety of factors.
These factors include:

           o changes in demand by the end user for our customers' products;

           o timing and amount of orders from our customers, including
                cancellations and reschedulings;

           o the gain or loss of significant customers, including as a result
                of industry consolidation;

           o changes in the mix of products sold by us, including the mix
                between processors and development tools and application
                software;

           o timing of "design wins" with related software application and
                development tool revenue, which have much greater average
                selling prices than individual communications processors;

           o market acceptance of our current and new products;

           o new product introductions by us or our competitors;

           o variability of our customers' product life cycles;

           o erosion of average selling prices due to a number of factors,
                including our customers reaching volume production, rapid
                technological change, price/
                performance enhancements and product obsolescence;

           o cancellations, changes or delays of deliveries to us by our
                suppliers, including the availability and terms of foundry
                capacity;

           o the cyclical nature of the semiconductor industry;

           o significant increases in expenses associated with the expansion of
                operations; and

           o general economic conditions.

     Revenue derived from communications processors is dependent upon design
wins, production ramp-up and the timing of orders due to customers' management
of inventory. Revenue from the licensing of application software and
development tools primarily coincides with design wins at new customers and in
limited instances at existing customers. Our gross margins are impacted by
changes in the mix of revenue between software and communications processors.
As a result of these factors, our lengthy sales cycle and our dependence on
relatively few customers whose order cycles vary significantly, we expect our
revenue and gross margins to fluctuate significantly from period to period.


                                       7
Risk Factors
<PAGE>

   
     These and other factors could materially and adversely affect us. You
should be aware that we cannot accurately forecast all of the above factors. We
believe that period-to-period comparisons are not necessarily meaningful and
should not be relied upon as indicative of future operating results.
    

     Our operating results in a future quarter or quarters may fall below the
expectations of public market analysts or investors. In such event, the price
of our common stock will likely be materially and adversely affected.


   
We Have a Costly and Lengthy Sales Cycle Which May Increase Our Exposure to
   Customer Cancellations or Similar Risks

     Our sales cycle typically includes a three to six month evaluation and
test period, a twelve to eighteen month development period by our customers and
an additional three to six month period before a customer commences volume
production of equipment incorporating our products. This lengthy sales cycle
creates risks related to customer decisions to cancel or change product plans,
which could result in the loss of anticipated sales. During our sales cycle,
our engineers assist our customers in implementing our solutions into their
product. We incur significant research and development and selling, general and
administrative expenses as part of this process before we generate the related
revenues from such customer. If our design is not selected, we derive no
revenue from this process. Achieving a "design win" with a communications
systems vendor provides no assurance that such communications systems vendor
will ultimately ship products incorporating our communications processors. It
is possible a customer may cancel orders even after we have achieved a design
win. We could be materially and adversely affected if customers curtail, reduce
or delay orders during our sales cycle, choose not to use our products or
choose not to release products employing our communications processors.


Our Revenues Could Decrease If There Is a Slowdown in the Growth in Demand for
   Communications Systems

     We derive all of our revenues from the sale of communications processors,
development tools and application software to communications markets. These
markets are characterized by intense competition and rapid technological
change. Although these markets have grown rapidly in the last few years, we
cannot be certain that they will continue to grow or that a significant
slowdown in these markets will not occur.

     In addition, a substantial majority of our revenues have been, and are
expected to continue to be, derived from sales of products for Asynchronous
Transfer Mode equipment. We have announced new products directed at
communications systems that are based on other technologies. If these other
technologies were to quickly achieve widespread acceptance before our new
products have achieved market acceptance, or if our new products do not achieve
market acceptance, we will be materially and adversely affected.


Our Success Depends upon Our Customers' Acceptance of Our Processors as an
   Alternative to Traditional Solutions

     Our future prospects depend on the acceptance of programmable
communications processors as an alternative to fixed-function devices and
general purpose processors traditionally used by communications systems
vendors. We would be materially and adversely affected if:

     o communications systems vendors do not accept programmable communications
processors;

     o communications systems vendors develop or acquire the technology to
       develop such components internally rather than purchase our products; or
        

     o we are otherwise unable to develop strong relationships with
       communications systems vendors.

     Our future prospects also depend upon acceptance by our customers of third
party sourcing for communications processors as an alternative to in-house
development. Many of our current and
    


                                       8
                                                                    Risk Factors
<PAGE>

   
potential customers have substantial technological capabilities and financial
resources which enable them to develop fixed-function components and to program
general purpose processors used in their products. In the future, these
customers may continue to use internally-developed fixed-function components
and general purpose processors or may decide to develop or acquire components,
technologies or communications processors that are similar to, or are
substitutes for, our products.


Our Failure to Introduce New Products on a Timely Basis Could Diminish Our
   Ability to Attract and Maintain Customers

     The communications systems industry is characterized by rapidly changing
technology, frequent product introductions and evolving industry standards. Our
products are based on these continually evolving industry standards. New
standards and protocols could render our existing products unmarketable or
obsolete. We may not be able to successfully design and manufacture new
products that comply with these standards and protocols. Specifically, our
future performance depends on a number of factors, including our ability to:
    

     o identify target markets and emerging technological trends in these
       markets, including new standards and protocols;

     o define new products accurately;

     o develop and maintain competitive products by improving performance and
       adding innovative features that differentiate our products from those of
       our competitors;

     o bring products to market on a timely basis at competitive prices; and

     o respond effectively to new technological changes or new product
announcements by others.

   
     We cannot assure you that the design and introduction schedules for any
additions and enhancements to our existing and future products will be met,
that these products will achieve market acceptance or that we will be able to
sell these products at average selling prices that are favorable to us.


Our Future Success is Dependent on the Release and the Acceptance of Our New
MXT4400 Processor

     We announced our newest product, the MXT4400 Traffic Stream Processor, in
March 1999. While we have delivered design plans for the MXT4400 to our
foundry, we have not yet been provided with finished prototypes. We cannot be
certain that the MXT4400 will perform as anticipated or that there will not be
unforeseen delays in its final release. Our failure to release the product on
schedule or the failure of the MXT4400 to meet our customers' expectations
would materially and adversely affect us. We do not expect to receive
significant revenues from the MXT4400 in 1999, and we cannot assure you that
future revenues will be sufficient to recover the costs associated with its
development.

     Products as complex as those such as the MXT4400 frequently contain
errors, defects and bugs when first introduced or as new versions are released.
Delivery of products with production defects or reliability, quality or
compatibility problems could require significant expenditures of capital and
resources and significantly delay or hinder market acceptance of such products.
This could damage our reputation and adversely affect our ability to retain our
existing customers and to attract new customers.


Our Revenues and Profits May Decrease if We Lose Any of Our Major Customers

     Historically, a relatively small number of customers have accounted for a
significant portion of our total revenues in any particular period. The loss of
any such single customer would have a material adverse effect on us. Maker's
top three customers in 1998 accounted for 29%, 16% and 13% of revenues. No
other customer accounted for revenues greater than 10% in 1998. We anticipate
that sales of our products to relatively few customers will continue to account
for a significant portion of our total revenues. We have no long-term volume
purchase commitments from any of our significant customers. Each of our
customers could cease purchasing our products with limited notice and with
little or no penalty.
    

     Our dependence on few customers increases our exposure to potential
adverse consequences resulting from business combinations or consolidations of
our customers. Specifically, two of our top


                                       9
Risk Factors
<PAGE>

   
five customers are in the process of completing such a consolidation. We cannot
assure you that such consolidation will not result in the cancellation of
current products. This industry may experience further consolidation in the
future and we cannot assure you that such consolidation would not result in
product duplication and a resulting cancellation of current projects or that
such consolidation will not materially and adversely affect us. Furthermore,
Lucent, who is one of our top five customers, is also a competitor of ours. It
is possible that Lucent could change its purchase patterns because of this
relationship.
    

     Our relationships with many of our manufacturers' representatives have
been established within the last year, and we are unable to predict the extent
to which some of these representatives will be successful in marketing and
selling our products. We cannot be certain that our current customers will
continue to place orders with us, that orders by existing customers will
continue at the levels of previous periods or that we will be able to obtain
orders from new customers.


   
Our Limited Resources Make Us More Susceptible to Competitive Pressures in the
Marketplace
    

     A number of our competitors are more established, benefit from greater
market recognition and have substantially greater financial, development,
manufacturing and marketing resources than we have. Moreover, several of the
largest electronics and semiconductor suppliers have recently entered or
indicated an intent to enter the communications market for semiconductor
devices.

   
     Intel has announced an intention to expand its presence in the networking
business, and has announced an agreement to acquire Level One Communications,
one of our stockholders. We have an agreement with Level One that requires us
to disclose to Level One upon request (and its successors, which would include
Intel) early versions of technology incorporated into our MXT3010 Cell
Processor, MXT3020 Co-Processor and related software applications. Our
agreement with Level One does not permit this technology to be incorporated in
a product that competes with us.

     In addition, many of our existing and potential customers internally
develop processors and other devices which attempt to perform all or a portion
of the functions performed by our products.
    

     Our ability to compete successfully in the rapidly evolving area of
high-performance communications processors depends on factors both within and
outside our control, including:

     o performance;

     o price;

     o features and functionality;

     o adaptability of products to specific applications;

     o support of product differentiation by our customers;

     o length of development cycle;

     o design wins with major communications systems vendors;

     o support for new communications standards and protocols;

   
     o reliability;
    

     o technical service and support; and

     o protection of products by effective utilization of intellectual property
laws.

   
     Our failure to compete successfully as to any of these or other factors
could materially and adversely affect us. To the extent that our competitors
offer sales representatives more favorable terms or a higher volume of
business, our sales representatives may decline to carry, or discontinue
carrying, our products.

                                                                    Risk Factors
<PAGE>

   
The Loss of Any of Our Key Personnel or the Failure to Hire Additional
   Personnel Could Impact Our Ability to Meet Customer and Technological
   Demands

     Our success depends to a significant degree upon the continued
contributions of our key management, engineering, sales and marketing and
manufacturing personnel, many of whom would be difficult to replace. The loss
of the services of any of our key personnel, the inability to attract or retain
qualified personnel in the future or delays in hiring required personnel,
particularly engineers and sales personnel, could materially and adversely
affect us. In particular, the loss of either of our founders, William Giudice,
President and Chief Executive Officer, and Paul Bergantino, Vice President and
Chief Technology Architect, could reduce our future success. We have neither
employment contracts with, nor key person life insurance on, any of our key
personnel.

     Competition for highly skilled managerial, engineering, sales and
marketing, finance and manufacturing personnel is intense and there can be no
assurance that we will be successful in attracting and retaining such
personnel.


We Depend on Outside Manufacturers to Make Our Products

     We currently outsource all manufacturing, assembly and test of our
communications processors to three outside foundries. In 1998, substantially
all of our manufacturing was outsourced to IBM, who is also a competitor. In
addition, each of our processors is manufactured for us by only one supplier.
These suppliers may allocate, and in the past have allocated, capacity to the
production of other products while reducing deliveries to us on short notice.
There are other significant risks associated with our reliance on outside
foundries, including:
    

     o the lack of assured semiconductor wafer supply and control over delivery
schedules;

     o the unavailability of, or delays in obtaining access to, key process
technologies;

     o limited control over quality assurance, manufacturing yields and
     production costs; and

     o penalties for failure to achieve targeted volume commitments.

   
     Currently, our suppliers quote a lead time for new orders of approximately
13 to 15 weeks in advance of expected delivery which requires us to place
orders in advance of expected purchase orders from our customers. As a result,
we have only a limited ability to react to fluctuations in demand for our
products, which could cause us to have an excess or a shortage of inventory of
a particular product. We have experienced delays and may in the future
experience delays in receiving supplies of products, and we cannot assure you
that we will be able to obtain such products within the time frames and in the
volumes required by us at an affordable cost or at all. Our failure to obtain
such products on a timely basis at a favorable cost could materially and
adversely affect us.

     Moreover, any failure of global semiconductor manufacturing capacity to
increase in line with demand could cause foundries to allocate available
capacity to larger customers or customers with long-term supply contracts. Our
independent manufacturers' inability to provide adequate foundry capacity at
acceptable prices, or any delay or interruption in supply, could reduce our
product revenues or increase our cost of revenues and could materially and
adversely affect us.
    

     In 1999, we will begin investigating the potential for assuming greater
manufacturing responsibilities during 2000. These responsibilities may include
contracting for wafer manufacturing and subcontracting for assembly and test
rather than purchasing finished product. The assumption of greater
manufacturing responsibilities involves additional risks, including not only
the risks discussed above but also risks associated with variances in
production yields, obtaining adequate test and assembly capacity at a
reasonable cost and other general risks associated with the manufacture of
semiconductors.


   
We Need to Protect Our Intellectual Property and Avoid Infringement of the
Intellectual Property of Others

     Our success depends in part on our ability to obtain patents and licenses
and to preserve other intellectual property rights covering our products and
development and testing tools. In particular, the rapidly evolving nature of
the semiconductor industry requires that companies continually seek and
    


                                       11
Risk Factors
<PAGE>

   
maintain patent protection of their technology. To that end, we have obtained
certain domestic and foreign patents and intend to continue to seek patents on
our inventions when appropriate. The process of seeking patent protection can
be time consuming and expensive. We cannot ensure that:
    

     o patents will issue from currently pending or future applications;

     o our existing patents or any new patents will be sufficient in scope or
       strength to provide meaningful protection or any commercial advantage to
       us;

     o foreign intellectual property laws will protect our intellectual
property rights; or

     o others will not independently develop similar products, duplicate our
       products or design around any patents issued to us.

     Intellectual property rights are uncertain and involve complex legal and
factual questions. We may be unknowingly infringing on the proprietary rights
of others and may be liable for that infringement, which could result in
significant liability for us. We have not been informed that we infringe any
third party intellectual property rights that would prevent our use and sale of
our products. If we do infringe the proprietary rights of others, we could be
forced to either seek a license to intellectual property rights of others or
alter our products so that they no longer infringe the proprietary rights of
others. A license could be very expensive to obtain or may not be available at
all. Similarly, changing our products or processes to avoid infringing the
rights of others may be costly or impractical.

     If we were to become involved in a dispute regarding intellectual
property, whether ours or that of another company, we may have to participate
in legal proceedings. These types of proceedings may be costly and time
consuming for us, even if we eventually prevail. If we do not prevail, we might
be forced to pay significant damages, obtain a license or stop making a certain
product.

     We also rely on trade secrets, proprietary know-how and confidentiality
provisions in agreements with employees and consultants to protect our
intellectual property. Other parties may not comply with the terms of their
agreements with us, and we may not be able to adequately enforce our rights
against these parties.


   
Rapid Growth Could Strain Our Resources

     We have experienced a period of rapid growth and expansion which has
placed, and continues to place, a significant strain on our resources. This
growth, as well as our product development activities, has required us to
increase our number of employees, which has resulted in increased
responsibilities for our management. As we continue to expand we may
significantly strain our management, manufacturing, financial, systems and
other resources. We cannot be certain that our systems, procedures, controls
and existing space will be adequate to support our operations.
    


The Price of Our Common Stock May Fluctuate Significantly

   
     The market for securities of high technology companies in the
semiconductor and communications systems industries has been highly volatile.
It is likely that the price of our common stock will fluctuate widely in the
future. Factors affecting the trading price of our common stock include:
    

     o responses to quarter-to-quarter variations in operating results;

     o announcements of technological innovations or new products by us or our
competitors;

     o general conditions in the communications system market; and

     o changes in earnings estimates by analysts.


Certain Factors May Delay or Prevent a Change of Control Transaction

   
     Delaware corporate law contains, and our certificate of incorporation and
by-laws contain, provisions that could have the effect of delaying, deferring
or preventing a change in control of our Company on terms which you may deem
advantageous. These provisions could limit the price that certain investors
might be willing to pay in the future for shares of our common stock. These
provisions:
    


                                       12
                                                                    Risk Factors
<PAGE>

     o authorize the issuance of "blank check" preferred stock (preferred stock
       which our board of directors can create and issue without prior
       stockholder approval) with rights senior to those of common stock;

     o provide for a board of directors with staggered terms;

     o prohibit stockholder action by less than unanimous written consent; and

     o establish advance notice requirements for submitting nominations for
       election to the board of directors and for proposing matters that can be
       acted upon by stockholders at a meeting.


   
A Limited Number of Stockholders Will Have the Ability to Influence Our
Policies Following the Offering

     A substantial majority of our capital stock is held by a limited number of
stockholders. After completion of this offering, our officers and directors and
parties affiliated with or related to such persons or to Maker will own
approximately 74% of the shares of common stock outstanding. Accordingly, such
stockholders will likely control major decisions of corporate policy and
determine the outcome of any major transaction or other matter submitted to our
stockholders or board of directors, including potential mergers or
acquisitions, and amendments to our certificate of incorporation. Stockholders
other than these principal stockholders are therefore likely to have little or
no influence on decisions regarding such matters.


The Price of Our Stock Could Decrease as a Result of Shares Being Sold in the
   Market After the Offering
    

     The market price of our common stock could drop as a result of sales of a
large number of shares of common stock in the market after the offering, or the
perception that such sales could occur. These factors also could make it more
difficult for us to raise funds through future offerings of common stock.

   
     There will be 17,454,833 shares of common stock outstanding immediately

Risk Factors
<PAGE>

                                USE OF PROCEEDS

   
     We estimate that we will receive net proceeds from this offering of
approximately $31,550,000, or $36,432,500 if the underwriters exercise their
over-allotment option in full, assuming an initial public offering price of
$10.00 per share after deducting the estimated underwriting discount and
offering expenses. We will use the net proceeds for working capital, to redeem
the Class A Redeemable Preferred Stock in the amount of $8,635,000, to repay
bank debt (approximately $1,328,000 at March 31, 1999), and for other general
corporate purposes. Borrowings under the bank debt bear interest at the prime
rate plus .25% to 1.0% and mature in May 2002. Pending these uses, we intend to
invest the proceeds in investment-grade, interest-bearing investments.

     The principal purposes of this offering are to increase our capitalization
and financial flexibility, to provide a public market for our common stock and
to facilitate access to public equity markets. As of the date of this
prospectus we cannot specify with certainty all of the particular uses for the
remaining net proceeds we will have upon completion of the offering.
Accordingly, our management will have broad discretion in the application of
net proceeds.
    


                                DIVIDEND POLICY

     We have never declared or paid cash dividends on our capital stock. We
currently anticipate that we will retain all available funds for use in our
business, and do not anticipate paying any cash dividends in the foreseeable
future. In addition, our existing lines of credit prohibit the distribution of
dividends without the lender's consent.

                                CAPITALIZATION

   
     The following table sets forth our capitalization as of March 31, 1999.
Our capitalization is presented:
    

     o on an actual basis;

   
     o on a pro forma basis to give effect to the automatic conversion of all
       outstanding shares of Junior Convertible Preferred Stock, Class B
       Convertible Preferred Stock, Class C Convertible Preferred Stock which
       will occur upon the closing of this offeing and the conversion into
       common stock of a convertible note prior to or upon the closing of this
       offering into an aggregate of 7,833,433 shares; and

     o on a pro forma as adjusted basis to reflect our receipt of the estimated
       net proceeds from the sale of 3,500,000 shares of common stock at an
       assumed initial public offering price of $10.00 per share after
       deducting the estimated underwriting discount and offering expenses, the
       redemption of all outstanding shares of Class A Redeemable Preferred
       Stock for $8,635,000 and the repayment of bank debt (approximately
       $1,328,000 at March 31, 1999).

                                   DILUTION

   
     The pro forma net tangible book value of the common stock as of March 31,
1999 was $4,266,000, or $.31 per share, after giving effect to the automatic
conversion of all outstanding shares of Junior Convertible Preferred Stock,
Class B Convertible Preferred Stock and Class C Convertible Preferred Stock
into an aggregate of 7,708,433 shares of common stock which will occur upon the
closing of this offering, as well as the conversion into common stock of a
convertible note on or prior to the closing of this offering. After giving
effect to the sale of the common stock pursuant to this offering at an assumed
initial public offering price of $10.00 per share, assuming that the
underwriters' over-allotment option is not exercised, and after deducting the
estimated underwriting discount and expenses of the offering, the adjusted pro
forma net tangible book value at March 31, 1999, would have been $36,079,000,
or $2.07 per share.

     Pro forma net tangible book value per share before the offering has been
determined by dividing pro forma net tangible book value (total tangible assets
less total liabilities) by the pro forma number of shares of common stock
outstanding at March 31, 1999. The offering will result in an increase in pro
forma net tangible book value per share of $1.76 to existing stockholders and
dilution in pro forma net tangible book value per share of $7.93 to new
investors who purchase shares in the offering. Dilution is determined by
subtracting pro forma net tangible book value per share from the assumed
initial public offering price of $10.00 per share. The following table
illustrates this dilution:

(1) After deduction of the estimated underwriting discount and offering
 expenses totaling $3,450,000.


     If the underwriters' over-allotment option were exercised in full, the pro
forma net tangible book value per share after the offering would be $2.28 per
share, the increase in net tangible book value per share to existing
stockholders would be $1.97 per share and the dilution to persons who purchase
shares in the offering would be $7.72 per share.

     The following table summarizes, on a pro forma basis as of March 31, 1999,
the differences between the total consideration paid and the average price per
share paid by the existing shareholders and the new investors with respect to
the number of shares of common stock purchased from us based on an assumed
initial public offering price of $10.00 per share:

     These tables do not assume exercise of stock options outstanding at March

issuable upon exercise of outstanding stock options at a weighted average
exercise price of $1.98 per share. To the extent that outstanding options are
exercised in the future, there will be further dilution to new investors.

                     SELECTED CONSOLIDATED FINANCIAL DATA

     The selected consolidated financial data of Maker set forth below as of
December 31, 1997 and 1998 and for each of the years ended December 31, 1996,
1997 and 1998 are derived from consolidated financial statements of Maker
audited by Arthur Andersen LLP, independent public accountants, which are
included elsewhere in this prospectus. The selected consolidated financial data
as of December 31, 1994, 1995 and 1996 and for the period from inception
(October 21, 1994) through December 31, 1994 and the year ended December 31,
1995 are derived from audited consolidated financial statements of Maker which
are not included in this prospectus. The selected financial data as of March
31, 1999 and for the three months ended March 31, 1998 and 1999 are derived
from Maker's unaudited Consolidated Financial Statements which are included
elsewhere in this prospectus and which include, in the opinion of Maker, all
adjustments (consisting only of normal recurring adjustments) that are
necessary for a fair presentation of its financial position and the results of
its operations for those periods. Operating results for the three months ended
March 31, 1999 are not necessarily indicative of the results that may be
expected for the fiscal year ending December 31, 1999. The pro forma basic and
diluted net loss per share is described in Note 2(e) of Notes to Consolidated
Financial Statements. The pro forma March 31, 1999 balance sheet data reflects
the automatic conversion of all the outstanding shares of Junior Convertible
Preferred Stock, Class B Convertible Preferred Stock and Class C Convertible
Preferred Stock into common stock which will occur upon the closing of this
offering, as well as the conversion into common stock of a convertible note
prior to or upon the closing of this offering. The data should be read in

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

     The following discussion of the financial condition and results of
operations of Maker should be read in conjunction with the Consolidated
Financial Statements and the Notes thereto included elsewhere in this
prospectus. Maker's actual results could differ significantly from those
discussed in these forward-looking statements as a result of certain factors,
including those set forth under "Risk Factors" and elsewhere in this
prospectus.


Overview

     Maker is a leading developer of high-performance programmable
communications processors, development tools and application software for
communications markets requiring high-intensity communications processing. From
its inception in October 1994 through 1996, Maker was engaged principally in
research and development, and a substantial portion of Maker's operating
expenses during such period was related to such activities. Maker commenced
volume shipments of its MXT3010 Cell Processors and related development tools
and application software in 1997. Substantially all of Maker's revenue to date
has been derived from the sales of the MXT3010 Cell Processor and related
software.

   
     Maker recognizes product revenue upon shipment of its communications
processors. Maker recognizes revenue from software license agreements upon
execution of a license agreement and delivery of the software. Software license
agreements may include royalty fees based upon customer shipments, revenue from
which is recognized upon payment to Maker. Maker recognizes revenue from
software maintenance agreements ratably over the term of the maintenance
period, which is typically one year.

     Maker's sales cycle typically includes a three to six month evaluation and
test period, a twelve to eighteen month development period by its customers and
an additional three to six month period before a customer commences volume
production of equipment incorporating its products. Maker's engineers work
closely with its customers in designing and implementing its solutions into
their products. Maker incurs significant research and development and selling
and administrative expenses as part of this process before it generates any
related revenue from such customer.

     Revenue derived from communications processors is dependent upon design
wins, production ramp-up and the timing of orders due to customers' management
of inventory. Revenue from the licensing of software and development tools
primarily coincides with design wins at new customers and in limited instances
at existing customers. New design wins with existing customers who have
previously licensed the Company's software generally do not result in
additional software licensing revenue. Since software revenues have no material
direct cost, Maker's gross margins are impacted by changes in the mix of
revenues between software and communications processors. As a result, Maker's
revenue and gross margins can fluctuate from period to period.

     Maker markets and sells its products primarily through a direct sales
force in the United States, manufacturers' representatives in the United States
and Canada and a distributor in Japan. Substantially all of Maker's sales to
date have been to customers located in the United States. In its latest fiscal
year, sales in the United States accounted for approximately 92% of Maker's
revenues.

     Maker's top five customers in 1998 were Ascend, Cisco, Fore, Lucent and
Nortel. Maker expects that these five customers will continue to account for a
significant portion of Maker's total 1999 revenues. Maker's top three customers
in 1998 accounted for 29%, 16%, and 13% of 1998 revenues. No other single
customer accounted for more than 10% of 1998 revenues. Lucent and Ascend
recently announced that they have entered into a definitive agreement pursuant
to which they will combine their operations. Maker expects that significant
customer concentration will continue for the foreseeable future. Maker's
customers typically place large orders which could cause revenues to fluctuate
significantly from period to period.

Management's Discussion and Analysis of
Financial Condition and Results of Operations
<PAGE>

Results of Operations


   
  Three Months Ended March 31, 1998 and 1999

     Total Revenues. Total revenues increased from $1.0 million for the three
months ended March 31, 1998 to $3.2 million for the three months ended March
31, 1999. The increase in total revenues primarily reflects an increased number
of customers reaching volume production.

     Cost of Revenues. Cost of revenues increased from $486,000 for the three
months ended March 31, 1998 to $1.0 million for the three months ended March
31, 1999. The increase is primarily due to increased revenues as well as the
cost of additional personnel to support the Company's customers. The gross
margin increased from 52% for the three months ended March 31, 1998 to 67% for
the three months ended March 31, 1999. The increase in gross margin reflects
lower product cost as a result of the Company meeting volume purchase
commitments and the absorption of fixed costs over higher revenues. Cost of
revenues includes the cost of purchasing fully assembled, tested and packaged
communications processors from Maker's independent foundries, production
related expenses, warranty and quality assurance for those products, as well as
costs of personnel associated with supporting Maker's customers. Cost of
revenues also includes software costs consisting of the costs of the media in
which it is delivered; these costs are not significant.

     Research and Development Expenses. Research and development expenses
increased from $894,000 for the three months ended March 31, 1998 to $1.3
million for the three months ended March 31, 1999. The increase primarily
reflects additional personnel and recruiting costs. Research and development
expenses consist primarily of salaries and related costs of employees engaged
in research, design and development activities.

     Selling and Marketing Expenses. Selling and marketing expenses increased
from $443,000 for the three months ended March 31, 1998 to $515,000 for the
three months ended March 31, 1999. The increase primarily reflects product
marketing costs associated with the introduction of MXT4400 Traffic Stream
Processor in March 1999 and increased salaries. Selling and marketing expenses
consist mainly of employee-related expenses, commissions to sales
representatives, product marketing and promotional expenses.

     General and Administrative Expenses. General and administrative expenses
increased from $341,000 for the three months ended March 31, 1998 to $394,000
for the three months ended March 31, 1999. The increase primarily reflects
increased accounting and legal fees and recruiting costs. General and
administrative expenses consist substantially of expenses to support the
business, including, corporate, accounting, legal, information technology
systems and human resources.

     Litigation. In July 1998, Maker settled a lawsuit with LSI Logic
Corporation. Costs associated with the litigation and settlement of the lawsuit
were $171,000 for the three months ended March 31, 1998.

     Interest Income. Interest income increased from $133,000 for the three
months ended March 31, 1998 to $160,000 for the three months ended March 31,
1999. The increase reflects interest earned on higher balances of cash and cash
equivalents.

     Interest Expense. Interest expense increased from $10,000 for the three
months ended March 31, 1998 to $41,000 for the three months ended March 31,
1999. The increase was due to the increased borrowing under Maker's equipment
line of credit to finance the purchase of capital equipment.


     Years Ended December 31, 1996, 1997 and 1998

     Total Revenues. Total revenues increased from $342,000 in 1996 to $1.8
million in 1997 to $7.7 million in 1998. Maker commenced sales of its products
in late 1996 and substantially increased shipments to its new and existing
customers in 1997 and 1998. The increase in revenues reflects certain customers
reaching volume production and increased software revenues from new customer
design wins.


     Cost of Revenues. Cost of revenues increased from $329,000 in 1996 to $1.0
million in 1997 to $3.2 million in 1998. The increase in cost of revenues is
primarily due to the increase in revenues as well

                                   Financial Condition and Results of Operations
<PAGE>

   
as an increase in pre-production costs. The gross margin increased from 4% in
1996 to 42% in 1997 to 58% in 1998. The increase in gross margin reflects the
absorption of fixed costs such as production related expenses and personnel
costs associated with supporting Maker's customers due to a greater sales
volume.

     Research and Development Expenses. Research and development expenses
increased from $1.2 million in 1996 to $2.7 million in 1997 to $4.2 million in
1998. The increase in 1997 reflects the continued development of the MXT3010
Cell Processor and related development tools and application software and the
development of the MXT3020 Circuit Co-processor and related development tools
and application software. The increase in 1998 primarily reflects the
development of the MXT4400 Traffic Stream Processor and related development
tools and application software and the continued development of development
tools and application software for the MXT3010 Cell Processor.

     Selling and Marketing Expenses. Selling and marketing expenses increased
from $332,000 in 1996 to $883,000 in 1997 to $2.1 million in 1998. The
increases were primarily due to additional personnel, including senior level
management, increased product marketing costs associated with new products,
increased commissions as a result of higher sales and costs associated with the
establishment of a sales office in Santa Clara, California in 1998.

     General and Administrative Expenses. General and administrative expenses
increased from $373,000 in 1996 to $751,000 in 1997 to $1.3 million in 1998.
The increases were primarily due to the hiring of additional personnel,
including senior level management, and costs associated with supporting the
business.
    

     Litigation Expense. In July 1998, Maker settled a lawsuit with LSI Logic
Corporation. Costs associated with the litigation and settlement of the lawsuit
were $462,000 in 1997 and $1.1 million in 1998.

   
     Interest Income. Interest income increased from $51,000 in 1996 to
$212,000 in 1997 to $538,000 in 1998. The increase reflects interest earned on
higher balances of cash and cash equivalents resulting from sales of preferred
stock in September 1996, October 1997 and December 1998.
    

     Interest Expense. Interest expense was $132,000, $33,000 and $82,000 in
1996, 1997 and 1998, respectively. The decrease in interest expense in 1997 was
primarily the result of the repayment of a note payable to one of Maker's
shareholders. The increase in interest expense in 1998 was due to increased
borrowing under Maker's equipment line of credit to finance the purchase of
capital equipment.

                                        Management's Discussion and Analysis of
                                   Financial Condition and Results of Operations

     During 1998 and the first quarter of 1999, revenues increased each
quarter, due primarily to growth in sales of communications processors. Over
the course of this period, several significant customers commenced shipment of
communications systems using Maker's communications processors. Gross margin
improved from 52% in the first quarter of 1998 to 67% in the first quarter of
1999, due primarily to Maker achieving volume shipments of the MXT3010 Cell
Processor which enabled Maker to absorb fixed costs over greater revenues.
Research and development expenses generally increased during this period due to
the addition of personnel and related costs. The increase in selling and
marketing expenses during this period is primarily due to an increase in
personnel and related costs.
    


Liquidity and Capital Resources

   
     Since its inception in 1994, Maker has financed its operations and capital
requirements from the sale of $23.9 million of preferred stock, borrowings
under an equipment line of credit of $1.6 million and revenue. Net cash used in
operating activities for the years ended December 31, 1996, 1997 and 1998 was
$2.0 million, $3.6 million and $1.8 million, respectively. Cash used in
operating activities consisted primarily of cash utilized to fund operating
losses and for working capital. In the first quarter of 1999, operating
activities generated $264,000 of cash primarily from working capital items. At
March 31, 1999, Maker had $14.3 million in cash and cash equivalents.

     Maker has a $2.5 million revolving line of credit facility and a $1.0
million equipment line of credit facility with a bank. Borrowings under both
facilities bear interest at the bank's prime rate plus .25% and expire in
February 2000. At March 31, 1999, Maker had not made any borrowings under
either facility. In addition, at March 31, 1999, Maker had $1.3 million
outstanding under equipment notes with the bank which bear interest at prime
plus .25% to prime plus 1.0% and which are repayable over approximately the
next three years. See Note 5 of Notes to Consolidated Financial Statements.

     From inception through March 31, 1999, Maker acquired $2.1 million in
capital assets. Maker intends to purchase approximately $1.0 million of
additional capital assets during 1999. A portion of Maker's future capital
expenditures will be devoted to enhancing and expanding Maker's operational
infrastructure, research and development tools and financial and management
information systems. Maker expects such expenditures to be funded out of
working capital or Maker's bank facilities.
    

     Maker currently uses independent suppliers to manufacture all of its
products. These arrangements allow Maker to avoid utilizing its capital
resources for manufacturing facilities and work-in-process inventory and focus
substantially all of its resources on the design, development and marketing of
its products. Maker expects to assume more responsibility for managing product
manufacturing in the future, which may require additional expenditures. Maker
anticipates that any such expenditures will be funded by working capital.

     Maker requires substantial working capital to fund its business,
particularly to finance accounts receivable and inventory, and for investments
in property and equipment. Maker believes the net proceeds of this offering
combined with its existing capital resources and cash generated from
operations, if any, will be sufficient to meet Maker's needs for the
foreseeable future, although Maker could seek to raise additional capital
during that period.


Income Taxes

     At December 31, 1998, Maker had available net operating loss carryforwards
of approximately $8.7 million for federal and state income tax purposes, which
expire at various dates through 2018. Maker also has available federal tax
credits of approximately $330,000 expiring through 2010. Maker has recorded a
full valuation allowance against its deferred tax asset due to uncertainties
surrounding the realization of these assets.

   
     The Internal Revenue Code of 1986, as amended, contains provisions that
may limit the net operating loss and tax credit carryforwards available to be
used in any given year upon the occurrence of certain events, including changes
in the ownership interests of significant stockholders. In the event of a
cumulative change in ownership in excess of 50% over a three year period, the
amount of the net operating loss carryforwards that Maker can utilize in any
one year may be limited. In the event of a
    


                                       22

Management's Discussion and Analysis of
Financial Condition and Results of Operations
<PAGE>

change in ownership the annual limitation on the use of the existing net
operating loss carryforwards is equal to an amount determined by multiplying
the value of Maker at the time of the ownership change by the federal
applicable rate of interest as determined by the Internal Revenue Service.
Maker has completed several financings since its inception and has incurred an
ownership charge as defined under the Code. The Company does not believe that
this change in ownership will have a material impact on its ability to utilize
its net operating loss and tax credit carryforwards.


Year 2000

     Many currently installed computer systems and software products are
dependent upon internal calendars coded to accept only two digit entries in the
date code field. These date code fields will need to accept four digit entries
to distinguish 21st century dates from 20th century dates. Computer systems and
software used by many companies may need to be upgraded to comply with such
"Year 2000" requirements. Maker has completed a review of its computer systems
to assess what steps, if any, are required to achieve full Year 2000
compliance. Based upon this review Maker believes that its systems are
currently Year 2000 compliant. Maker does not anticipate that it will incur
material expenses or meaningful delays in connection with Year 2000 compliance.
 

   
     None of our products use internal calendars that are dependent upon the
input of a specific date. As a result, all of our current products are
inherently Year 2000 compliant. Moreover, based on assessments made to date, we
do not anticipate material disruptions to our operations as a result of Year
2000 issues.

     Maker is currently discussing Year 2000 readiness with its material supply
and service vendors. To date, those vendors that have been contacted have
indicated that their hardware or software are or will be Year 2000 compliant on
a timely basis. However, Maker intends to continue through 1999 to assess its
exposure to Year 2000 noncompliance on the part of any of its material vendors
and there can be no assurance that their systems will be Year 2000 compliant.

     Maker believes that Year 2000 issues will not pose significant operational
problems for its business. Therefore, Maker does not have, and does not intend
to create, a contingency plan in the event Year 2000 compliance cannot be
achieved in a timely manner.

Industry Overview

   
     Public communications networks, such as those used by local and long
distance carriers, and specialized networks, such as those used by Internet
service providers, are experiencing dramatic growth in data traffic. This
increase in data traffic reflects a number of factors, including:

     o the explosive growth of the Internet;
   o the increase in demand for higher speed interconnectivity between wide
     area networks and local area networks; and
     o the growing demand for remote network access.

     While voice traffic is growing at a modest rate, data traffic is growing
much more rapidly and represents an increasing portion of the traffic carried
by public networks.

     Today's telecommunications infrastructure is primarily based on circuit
switched technology, which was developed to support voice communications.
Circuit switched technology creates a dedicated circuit with a fixed amount of
bandwidth for the duration of the connection, regardless of a user's actual
bandwidth usage. Circuit switched technology is inefficient for high speed data
transmission because data is transmitted in bursts and therefore has bandwidth
requirements that vary over time. As a result, today's public communications
networks do not have the bandwidth and cannot scale on a cost effective basis
to support the continuing increase in data traffic.

     In addition to the increase in traffic volume, the nature of the network
traffic is becoming increasingly complex. To differentiate themselves, network
service providers are offering, on a converged voice and data network
infrastructure, enhanced communications services such as:

     o guaranteed Internet access;
     o virtual private networks;
     o videoconferencing;
     o service level agreements; and
     o Internet Protocol telephony.

     The increase in the volume and complexity of traffic is driving the demand
for sophisticated network traffic management, which is an immature discipline
that is continuing to evolve. Communications systems vendors are developing
schemes that intelligently manage network traffic, such as Quality of Service
and Class of Service. Quality of Service guarantees a specific level of
end-to-end service across the network, while Class of Service prioritizes
service levels for different classes of users and applications.

     In order to provide improvements in capacity and service offerings, new
standards and protocols are constantly being developed and introduced into the
network infrastructure. These standards and protocols are being deployed into
networks in an evolutionary fashion due to the mission-critical nature of
communications networks and network service providers' large investment in
existing infrastructure. As a result, communications network infrastructures
are becoming more complex. This increasing complexity is driving the demand for
sophisticated internetworking, the translation function between different
network standards and protocols.

     Key standards and protocols that are emerging to address the limitations
of existing circuit switched networks include Asynchronous Transfer Mode and
Internet Protocol. Asynchronous Transfer
    


                                       24

Mode is based on fixed-sized packets, called cells, and is designed to
efficiently integrate voice, data and video and easily scale in capacity.
Internet Protocol is a packet-based protocol that is generally accepted as the
industry standard for local area network data transfer and is being
increasingly used in wide area network data transfer. Neither packet nor
Asynchronous Transfer Mode switching requires end-to-end fixed bandwidth for
dedicated circuits and therefore have inherent benefits over circuit switching
in terms of bandwidth utilization. Both Asynchronous Transfer Mode and Internet
Protocol packet switching network technologies are being deployed over optical
networks based on the complementary SONET/SDH standards, known as ATM over
SONET (Synchronous Optical Network) and Packet over SONET, or POS. SONET is a
cabling and signaling standard that is widely used in wide area networks for
carrying circuit switched, cell or packet-based traffic.
    

     Traditional systems vendors and multiple new entrants are competing to
meet the evolving requirements of advanced communications networks by
introducing increasingly sophisticated communications systems, including
switches, access devices, routers and transmission equipment. To achieve the
performance, functionality and price required by such communications systems,
communications systems vendors are using increasingly complex integrated
circuits. As a result of time-to-market pressures, constantly evolving
standards and protocols and the difficulty of designing and producing the
requisite integrated circuits, these vendors are increasingly using integrated
circuits supplied by specialized communications semiconductor companies.

   
     The key integrated circuit elements of a typical communications system
consist of physical connection elements, cell or packet processing device and
port interconnection. The physical connection elements convert and condition
the signal for transmission on or off the network cabling. The port
interconnection transfers data between ports through elements such as switching
fabrics or shared system busses. The cell or packet processing device performs
a variety of complex data manipulation functions, including traffic management
and internetworking. Of the three elements, cell or packet processing, because
of its broad functionality, provides communications systems vendors with the
greatest opportunity to differentiate their products with increased
functionality and features.

     Traditionally, communications systems vendors have utilized general
purpose processors, fixed- function Application Specific Standard Products
(ASSP) or custom developed, fixed-function devices, often implemented utilizing
Application Specific Integrated Circuits or ASICs, to provide the cell or
packet processing functions. General purpose processors are programmable and
therefore enable products to be brought to market relatively rapidly. They can
also be easily adapted to changes in industry standards and to add additional
features. However, these benefits are usually not achievable without
significant performance degradation. Fixed-function integrated circuits can be
designed to achieve high performance. However, fixed-function integrated
circuits cannot be adapted to changing functional requirements and must be
redesigned if errors are found in their implementation. Furthermore, developing
fixed-function integrated circuits for emerging applications is relatively time
consuming and limits the ability of communications systems vendors to meet
time-to-market constraints. Consequently, none of these approaches is ideal for
meeting the market requirements for high-performance cell or packet processing.

Markets and Applications

     Maker focuses on emerging high growth segments of the communications
systems markets requiring high-intensity communications processing. These
market segments are characterized by rapidly evolving performance and
functional requirements. Within these markets, Maker focuses on applications
that involve high-performance internetworking and network traffic management.
Internetworking is a translation function used to interconnect different
networks and protocols. Traffic management describes a collection of functions
which are involved in optimally using network bandwidth and providing
differentiated services over the network. In particular, traffic management is
critical in allowing data to be combined with delay-sensitive information, such
as voice or video, on a network.

   
     Asynchronous Transfer Mode and Internet Protocol networks are two markets
with significant traffic management and internetworking requirements.
Asynchronous Transfer Mode is based on fixed-sized packets, called cells, and
is designed to efficiently integrate voice, data and video and to easily scale
in capacity. Internet Protocol is a packet-based protocol that is generally
accepted as the industry standard for local area network data transfer and is
being increasingly used in wide area network data transfer. Maker's
high-intensity communications processing products are well suited for the high-
capacity and evolving functional requirements of Asynchronous Transfer Mode and
Internet Protocol networks. Maker's products address internetworking
applications, including Asynchronous Transfer Mode SARing, and a variety of
traffic management functions including traffic shaping, traffic policing and
queue management required by these markets.

     High-Performance SARing. SARing or Segmentation and Reassembly is the
internetworking function for translating between Asynchronous Transfer Mode and
packet-based networks, such as Ethernet, Frame Relay and Packet over SONET, or
time-division-multiplexed networks (commonly used in the telecommunications
infrastructure). SARing takes place in packet-based communications systems,
such as Ethernet switches and Internet routers in circumstances where an
Asynchronous Transfer Mode connection is required, or in Asynchronous Transfer
Mode-based systems such as multi-service wide area network switches where
packet interfaces such as Frame Relay or Packet Over SONET are required. Maker
was one of the first vendors to deliver a SAR that operates at OC-12 (622Mbps)
rates, and believes it is a leading provider of Asynchronous Transfer Mode SAR
devices in this market. An OC-12 SAR can support multiple configurations
including one OC-12 network port or 4 OC-3 (155Mbps) ports.

     Asynchronous Transfer Mode Traffic Shaping. Traffic shaping is a complex
function that determines the time and rate at which various categories of
network traffic can be sent onto the network. Maker supports this application
at rates up to OC-12 in Asynchronous Transfer Mode switches, typically located
at the edge between enterprise, carrier or service provider networks, and in
Asynchronous Digital Subscriber Line access multiplexers.

     Asynchronous Transfer Mode Traffic Policing. Traffic policing monitors
traffic coming into a port from the network and ensures that it conforms to
predetermined bandwidth policies. Maker supports this application at rates up
to OC-12 in Asynchronous Transfer Mode switches, typically located at the edge
between enterprise, carrier or service provider networks.

     Multi-Service Wide Area Network Access. Multi-Service wide area network
access applications allow service providers to supply a variety of Asynchronous
Transfer Mode, Frame Relay, or leased line services on demand on a line-by-line
basis through software control. These applications typically involve services
that require relatively low bandwidth but high computing power. Multi-service
wide area network access products also can integrate voice and data over a
single access line, offering potential economic benefits to the subscriber.
This functionality can be used in wide area network edge switches, Asynchronous
Transfer Mode access multiplexers, SONET add/drop multiplexers and wireless
base station equipment.

     Packet Over SONET Link Management. This emerging application supports
traffic management, including policing, shaping and queue management and
internetworking functions such as Multi-Protocol Label Switching (MPLS) for
Packet Over SONET ports in Internet routers and enterprise

switches. In the future, Maker expects the MXT4400 to support this application
at rates up to OC-12, with the future members of the MXT4000 family expected to
support rates up to OC-48.

     MXT4000 Traffic Stream Processor Family. The MXT4400 Traffic Stream
Processor is the first member of the MXT4000 family. The MXT4400 is a
high-performance, programmable packet and cell processor based on Maker's new
proprietary 32-bit RISC core. The MXT4000 family increases Maker's market
opportunity by allowing it to address the opportunity for Internet Protocol
based services, to provide lower customer system costs through higher levels of
integration, to support rates up to OC-48 (2.5 Gbps) and to support more
sophisticated traffic management and internetworking functions.
    

     Maker announced the introduction of the MXT4400 Traffic Stream Processor
in March 1999 and expects it to be in volume production in the second half of
the year. Maker has delivered Verilog simulation models of the MXT4400 to two
alpha customers, Lucent and Xylan. The design data base is at the foundry for
layout and an initial production run.


 Application Software

     Maker offers complete production-tested application software that runs on
the MXT3010 or MXT4400 processors. Customers may use this software as is,
customize it or write their own custom software to address specific
applications.

   
     CellMaker. CellMaker is SARing software that runs on the MXT3010 Cell
Processor. This application supports internetworking between Asynchronous
Transfer Mode and packet-based networks such as Ethernet or Frame Relay. Maker
offers versions of this software that support data rates of OC-3 (155Mbps) and
OC-12 (622Mbps).

     AccessMaker. AccessMaker is software that runs on the MXT3010 Cell
Processor coupled with up to four MXT3020 Circuit Coprocessors and supports the
integration of both voice and data over Asynchronous Transfer Mode networks.
AccessMaker allows customers to design a single piece of hardware that can
support many common T1/E1 services such as Frame Relay, Asynchronous Transfer
Mode, and leased lines in any combination up to 28 T1/E1 ports. This allows
service providers to provision new services to their end-user customers quickly
and cost-effectively through software control, rather than having to physically
reconfigure equipment using field technicians.

     PortMaker. PortMaker is software that runs on the MXT4400 Traffic Stream
Processor and supports OC-12 Asynchronous Transfer Mode SARing. This
application was announced with the MXT4400 in March 1999. Maker intends to
expand the application to support a common set of traffic management and
internetworking functions for Packet Over SONET and Asynchronous Transfer Mode
networks.
    


 Development Tools

     To accelerate time-to-market for new products, Maker offers customers a
full set of development tools including Verilog models, simulation
environments, assemblers and debuggers for both of Maker's processors, as well
as a variety of demonstration cards for the MXT3010. These tools allow
customers to write and debug software for systems based on Maker's processors
prior to using actual hardware and to simulate system and network operations
for the purpose of optimizing performance. Maker's tools also allow customers
to verify any custom hardware that they have developed to interface with
Maker's products. To further facilitate software development by its customers,
Maker expects to introduce a C compiler for the MXT4400 Traffic Stream
Processor.


Customers, Sales and Marketing

   
     Maker targets leading telecommunications and data networking vendors.
Maker has over 50 design wins with over 30 customers, of which over 15 were in
production during the first quarter of 1999. Maker defines a design win as a
discernible commitment by a vendor to use Maker products in a development
program that is funded, staffed and targeted for production. Maker can provide
no

   Juniper Networks                         Xylan
     Lucent Technologies

   
     Maker's top five customers in 1998 were Ascend, Cisco, Fore, Lucent and
Nortel. Maker's top three customers in 1998 accounted for 29%, 16% and 13% of
revenues. No other single customer accounted for more than 10% of 1998
revenues. Ascend and Lucent recently announced that they have entered into a
definitive agreement pursuant to which they will combine their operations. See
"Risk Factors--Our Revenues and Profits May Decrease If We Lose Any of Our
Major Customers."
    

     Maker's sales and marketing strategy is to achieve design wins with
industry leaders in emerging high growth segments of the communications systems
markets that require high-intensity communications processing. In many cases,
Maker's processors are a key element in the architectural designs of its
customers' communications systems. As a result, prior to a design win Maker's
engineers often act as consultants to its customers in early architectural
discussions and decisions.

     Maker markets and sells its products primarily through a direct sales
force in the United States; manufacturers' representatives in the United States
and Canada and a distributor in Japan. Maker has sales offices located in
Framingham, Massachusetts and Santa Clara, California. Maker selects its
independent manufacturers' representatives based on their understanding of the
communication processor marketplace and their ability to provide effective
field sales support for Maker's products.

   
     In its latest fiscal year, sales in the United States accounted for
approximately 92% of Maker's revenues. Although Maker achieved a number of
design wins with customers outside of the United States, none of these
customers has reached volume production.
    

     Maker targets its marketing efforts at identifiable industry leaders.
Maker has a number of marketing programs designed to inform communications
systems vendors about the capabilities and benefits of Maker's products.
Maker's marketing efforts include an emphasis on applications notes, design
examples and other technical documentation to accelerate customer designs. In
addition, for the purpose of building a high level of industry awareness,
Maker's marketing efforts also include participation in industry trade shows,
technical conferences and technology seminars, publication of technical and
educational articles in industry journals, maintenance of Maker's World Wide
Web site and press tours.

   
     Technical support to customers is provided through Maker system engineers
and, if necessary, product designers and architects. Local field support is
provided by systems engineers in person or by telephone. Maker believes that
providing communications systems vendors with comprehensive product service and
support is critical to maintaining a competitive position in the communications
market and is critical to shortening customers' design-in cycles. Maker works
closely with its customers to monitor the progress of its product designs and
to provide support at each stage of customer product development.

Technology

   
     Maker has developed proprietary communications processors that combine
high-speed performance with a programmable architecture. Maker's solution
architecture is comprised of both integrated circuits and software components,
including:
    

     o a proprietary, programmable processor;
   o a lightweight kernel that provides the basic software infrastructure upon
     which applications are written;
     o communications processing applications; and
   o a well-defined application programming interface that enables customers'
     systems to communicate with Maker's software.

   
To facilitate the development of specific applications, Maker also provides a
development environment and a library of performance-optimized software
routines that implement a number of common networking functions.
    

     Below is an overview of Maker's solution architecture:

</TABLE>



     The core technologies employed by Maker include its proprietary RISC
architecture, high-speed context switching, network traffic management
technology and TDM (Time Division Multiplexed) service internetworking
technology.

     Proprietary RISC Architecture. Maker's philosophy is to base its
processors on the fastest and most cost-effective processor cores for
communications applications. Rather than using commercially available RISC
processors such as MIPS or PowerPC, Maker has developed proprietary processor
cores which have an architecture and instruction set that are optimized for the
tasks of processing and switching data, voice and video in broadband networks.
Optimizing the instruction set allows these processors to perform common
communications processing steps using a minimum number of instructions,
delivering higher CPU performance and higher throughput at a given clock rate
than general purpose RISC or CISC processors can provide.

   
     High-Speed Context Switching. Maker's communications processors have
event-driven architectures that can quickly adapt to the arrival of new network
traffic or new traffic management information. One of the key differences
between communications processors and general purpose RISC processors is the
speed at which they perform context switching. Context is any descriptive
information, such as traffic contracts and network statistics, that the
processor requires to process a particular packet or Asynchronous Transfer Mode
cell. The processor must gather all of the context information that is
    


                                       31
                                                                        Business
<PAGE>

   
relevant to that particular cell, perform any necessary translation and traffic
management processing based on that context, and then store the updated context
before the next cell arrives. In OC-12 Asynchronous Transfer Mode networks, for
example, new Asynchronous Transfer Mode cells arrive every 680 nanoseconds. The
faster the processor can gather and store context, the more time that processor
has for cell or packet processing, thereby increasing the speed of the overall
solution.
    

     Network Traffic Management Technology. Maker has developed hardware and
software technology that provides an extensive set of programmable traffic
management capabilities intended to allow its customers to adapt to evolving
and increasingly sophisticated functional requirements. Traffic management is a
critical requirement for providing high-quality network services and supporting
the convergence of voice, data and video in the communications infrastructure.
Elements of Maker's solution include per-stream buffer queuing, traffic shaping
capability, congestion and flow control algorithms. These programmable
functions can allow network equipment to deploy sophisticated traffic
management services at very high performance levels.

   
     TDM Service Internetworking Technology. Maker has developed a specialized
software kernel which provides a unified methodology for managing a diverse set
of the most common T1/E1 and DS3 services such as Frame Relay, a variety of
Asynchronous Transfer Mode services, and leased lines. This is synergistic with
other Maker hardware and software technologies such as fast context switching
and advanced traffic management and is a core element of Maker's AccessMaker
application. The specialized software kernel allows network equipment to
integrate data, voice and video traffic and permits service providers to
provision new services to their customers on demand from a single equipment
platform.
    


Research and Development

     Maker focuses its research and development efforts on the development of
programmable high-performance communications processors, development tools and
   
applications software. As of March 31, 1999, Maker had 35 employees and
full-time contractors engaged in research and development, of which 15 are
involved in the development of development tools and applications software and
20 are involved in algorithm and integrated circuit design and verification.
Maker's research and development facilities are located at its headquarters in
Framingham, Massachusetts.
    

     Maker's research and development expenses for the years ended December 31,
1996, December 31, 1997 and December 31, 1998 were approximately $1.2 million,
$2.7 million and $4.2 million, respectively. Research and development expenses
primarily consist of salaries and related costs of employees engaged in ongoing
research, design and development activities.


Manufacturing

     Currently, Maker outsources all of its semiconductor manufacturing,
assembly and testing to suppliers that deliver fully assembled and tested
products to Maker on a turnkey basis. This fabless semiconductor manufacturing
model allows Maker to focus substantially all of its resources on the design,
development and marketing of products and significantly reduces its capital
requirements.

     In 1996 and 1997, Maker subcontracted its semiconductor manufacturing to
Toshiba, VLSI Technology and IBM. In 1998, substantially all of Maker's
manufacturing was subcontracted to IBM.

     Maker uses state-of-the-art, fully digital CMOS processes for the
manufacturing of its semiconductor devices. Maker's main products currently are
fabricated in .35 micron CMOS. Maker continuously evaluates the benefits of
adopting smaller geometry processes in order to achieve optimal performance and
cost.

   
     Maker will begin to investigate the possibility of assuming more
manufacturing responsibilities in 1999. Such changes may include contracting
for wafer processing, and subcontracting with other suppliers for assembly and
test. As a result of such changes, Maker would likely be required to enter into
volume purchase agreements pursuant to which Maker would commit to minimum
levels of purchases and which may require up front investments. See "Risk
Factors--We Depend on Outside Manufacturers to Make Our Products."

Competition

   
     The communications semiconductor industry is intensely competitive and is
characterized by constant technological change, rapid rates of product
obsolescence and price erosion. Maker products compete with fixed-function
integrated circuits and programmable integrated circuits which are typically
based on general purpose processors. In the OC-3 SAR market, Maker competes
with a number of competitors offering fixed-function devices including
Conexant, IBM, Texas Instruments, Integrated Device Technology, PMC-Sierra,
Lucent, Fujitsu, NEC and TranSwitch. In the developing OC-12 SAR market Maker
expects to compete with several of the foregoing among others. In the
Asynchronous Transfer Mode traffic policing market, there are a number of
competitors, including Lucent and PMC-Sierra. In Asynchronous Transfer Mode
markets, LSI Logic and Motorola currently offer programmable cell processing
capability.
    

     Competitive factors in the market for integrated circuits are:

     o performance;

     o impact of the integrated circuit on end-product cost;

     o adaptability to changing market requirements;

     o quality and availability of technical support;

     o feature set;

     o ease of designing with and debugging; and

     o compatibility with customer system architectures and complementary
components.

     In addition to the list above, programmable communication processors face
additional competitive factors such as:

     o ease of writing and debugging high-performance software;

     o availability of tools and software libraries;

     o completed software applications;

     o compatibility with customer simulation environments; and

     o scalability across a breadth of applications.

   
     Several of the largest electronics and semiconductor suppliers have
recently entered or indicated an intent to enter the communication market for
semiconductor devices. Many of Maker's existing and potential customers
internally develop fixed-function integrated devices, general purpose
processors, communications processors and other devices which attempt to
perform all or a portion of the functions performed by Maker's products. Maker
understands that there may be a number of smaller emerging companies that are
contemplating entering the communications processors market. In addition, Maker
also may face competition from suppliers of products based on new or emerging
technologies. See "Risk Factors--Our Limited Resources Make Us More Susceptible
to Competitive Pressures in the Marketplace."
    


Intellectual Property

   
     Maker's future success and ability to compete are dependent, in part, upon
its proprietary technology. Maker has been granted four patents in the United
States in the field of cell processors. These patents expire on May 9, 2016. In
addition, Maker has filed additional U.S. patent applications in the United
States. There can be no assurance that any patents will issue pursuant to
Maker's current or future patent applications or that patents issued pursuant
to such applications will not be invalidated, circumvented, challenged or
licensed to others. In addition, there can be no assurance that the rights
granted under any such patents will provide competitive advantages to Maker or
be adequate to safeguard and maintain Maker's proprietary rights. Not all of
Maker's proprietary technology is patented.

     In addition, Maker claims copyright protection for proprietary software
and documentation used in its products and software. Maker also attempts to
protect its trade secrets and other proprietary information through agreements
with its customers, suppliers, employees and consultants, and through other
security measures. Although Maker intends to protect its rights vigorously,
there can be no
    


                                       33
                                                                        Business
<PAGE>

assurance that these measures will be successful. In addition, the laws of
certain countries in which Maker's products are or may be manufactured or sold
may not protect Maker's products and intellectual property rights to the same
extent as the laws of the United States.

     While Maker's ability to compete may be affected by its ability to protect
its intellectual property, Maker believes that, because of the rapid pace of
technological change in the communications systems industry, its technical
expertise and ability to introduce new products on a timely basis will be more
important in maintaining its competitive position than protection of its
intellectual property. Maker believes that patent, trade secret and copyright
protection are important but must be supported by expanding the knowledge,
ability and experience of Maker's personnel and introducing and enhancing
products. Although Maker continues to implement protective measures and intends
to defend vigorously its intellectual property rights, there can be no
assurance that these measures will be successful.

     Many participants in the semiconductor and communications systems industry
have a significant number of patents and have frequently demonstrated a
readiness to commence litigation based on allegations of patent and other
intellectual property infringement. From time to time, third parties, including
competitors of Maker, may assert patent, copyright and other intellectual
property rights to technologies that are important to Maker. There can be no
assurance that third parties will not assert infringement claims against Maker
in the future, that assertions by third parties will not result in costly
litigation or that Maker would prevail in any such litigation or be able to
license any valid and infringed patents from third parties on commercially
reasonable terms, if at all. Litigation, regardless of the outcome, is likely
to result in substantial cost and diversion of resources of Maker. Any
infringement claim or other litigation against or by Maker could materially
adversely affect Maker's business, financial condition and results of
operations.

   
     In addition, there can be no assurance that competitors of Maker, many of
which have substantially greater resources than Maker and have made substantial
investments in competing technologies, do not have, or will not seek to apply
for and obtain, patents that will prevent, limit or interfere with Maker's
ability to make, use or sell its products either in the United States or in
international markets. Furthermore, there can be no assurance that Maker will
not in the future become subject to patent infringement claims and litigation
or interference proceedings to determine the priority of inventions due to the
significant number of patents in the industry. This large volume of patented
technology makes infringement more difficult to assess. The defense and
prosecution of intellectual property suits, interference proceedings and
related legal and administrative proceedings are both costly and time
consuming. Any such suit or proceeding involving Maker could have a material
adverse effect on Maker's business, financial condition and results of
operations. See "Risk Factors--We Need to Protect Our Intellectual Property and
Avoid Infringement of the Intellectual Property of Others."
    


Employees

   
     As of March 31, 1999, Maker had 60 full-time employees and 3 contract
employees. Of the total number of full-time employees and contract employees,
35 were in research and development, 17 were in sales, marketing and technical
support and 11 were in operations and administration. Maker's employees do not
have any collective bargaining agreement, and Maker has never experienced a
work stoppage. Maker believes its employee relations are good. See "Risk
Factors--The Loss of Any of Our Key Personnel or the Failure to Hire Additional
Personnel Could Impact Our Ability to Meet Customer and Technological Demands."
 
    


Facilities

     Maker's main executive, administrative and technical offices occupy
approximately 18,498 square feet in Framingham, Massachusetts, under a lease
that expires on June 30, 2000. Maker also leases a sales office in Santa Clara,
California.


Legal Proceedings

   
     Maker is not currently involved in any material legal proceedings.

Election of Directors

   
     After Maker files an Amended and Restated Certificate of Incorporation in
connection with this Offering, Maker's Amended and Restated Certificate of
Incorporation will provide for a classified board of directors divided into two
classes. Class I will expire at the annual meeting of stockholders to be held

held in 2001. Mr. Evans and Mr. Soni will initially serve as Class I Directors
and Mr. Giudice, Mr. Low and Mr. Tomasetta will initially serve as Class II
directors. At each annual meeting of stockholders, beginning with the 2000
annual meeting, the successors to directors whose terms will then expire will

second annual meeting following election and until their successors have been
duly elected and qualified, or until their earlier resignation or removal, if

(1) In accordance with the rules of the SEC, shown are the gains or "option
    spreads" that would exist for the respective options granted. These gains
    are based on the assumed rates of annual compound stock price appreciation
    of 5% and 10% from the date the option was granted over the full option
    term. These assumed annual compound rates of stock price appreciation are
    mandated by the rules of the SEC and do not represent Maker's estimate or
    projection of future common stock prices.

(2) Amounts represent hypothetical gains that could be achieved for the
    respective options if exercised at the end of the option term. These gains
    are based on assumed rates of stock price appreciation of 5% and 10%
    compounded annually from the date the respective options were granted to
    their expiration date based on the initial public offering price. These
    assumptions are not intended to forecast future appreciation of our stock
    price. The potential realizable value computation does not take into
    account federal or state income tax consequences of option exercises or
    sales of appreciated stock.

(1) Value is based on the difference between the option exercise price and the
    initial public offering price of the common stock multiplied by the number
    of shares of common stock underlying the option. No market existed for the
    common stock prior to this offering. Assumed offering price of $10.00;
    exercise prices range from $0.16 to $2.75.

(2) Options granted to executive officers under the 1996 Stock Option Plan are
    generally immediately exercisable, but subject to an optional right of
    repurchase by Maker at cost pursuant to the vesting schedule of each such
    grant. Accordingly, these options are exercisable but would be subject to
    repurchase since since they have not yet vested.

(3) Includes 114,275 shares which are subject to repurchase at cost by Maker
    pursuant to stock repurchase agreements.

(4) Includes 33,600 shares which are subject to repurchase at cost by Maker
pursuant to stock repurchase agreements.
    



Benefit Plans


     1996 Stock Option Plan

   
     The 1996 Stock Option Plan (1996 Plan) provides for the granting of
incentive stock options and non-qualified options defined in Section 422 of the
Internal Revenue Code to Maker's employees. The 1996 Plan is administered by
Maker's Board of Directors. The Board (a) interprets and applies the 1996 Plan,
(b) determines the eligibility of an individual to participate in the 1996
Plan, (c) approves the assignment of options immediately prior to the
registration of Maker's stock pursuant to the Securities Exchange Act of 1934,
as amended, if such assignment would increase the number of common stockholders
and (d) determines and allocates the cancellation or exchange of outstanding
options in the case of a recapitalization, acquisition, merger or change in
control. No options may be granted to an employee who, at the time of the
grant, owns more than 10% of the voting power or greater than 10% of each class
of Maker's outstanding stock, unless the purchase price of the stock is not
less than 110% of the stock's fair market value on the date of the grant and
the option, by its terms, shall not be exercisable more than five years from
the date it is granted. Upon the effectiveness of the Company's 1999 Incentive
Stock Plan, no further options shall be granted under the 1996 Plan.

     Vested options may be exercised in full at one time or in part from time
to time and the payment of the exercise price may be made by delivery of (a)
cash or a check payable to the order of Maker in an amount equal to the
exercise price of such options, (b) shares of Maker's common stock owned by the
optionee having a fair market value equal in amount to the exercise price of
the options being exercised, (c) the cancellation of shares covered by this
option which are then vested and exercisable having a fair market value equal
in amount to the purchase price of the shares being purchased, (d) any
combination of (a), (b), (c) and (d); provided, however, that payment of the
exercise price by delivery of shares of common stock owned by such optionee or
cancellation of shares covered by the option may be made only with the consent
of the Board if such payment results in a charge to earnings for financial
accounting purposes as determined by the Board. Maker may delay the issuance of
shares covered by the exercise of an option until (a) the shares for which such
option has been exercised have been registered or qualified under the
applicable federal or state securities laws or (b) counsel for Maker has opined
that such shares are exempt from the registration requirements of such federal
or state securities laws.

     Under the 1996 Plan, at the option of the board of directors, certain
options granted may be immediately exercisable but subject to a right of
repurchase pursuant to the vesting schedule of each such grant.
    

     The term of any option granted under the Plan shall be limited to ten
years. Upon the termination of an optionholder's employment with Maker, such
options shall terminate between 30 and 180 days after that optionholder leaves
the employ of Maker.

   
     As of March 31, 1999, 2,635,940 options were outstanding under the Plan.
Options granted vest over a term established by the board of directors at the
date of grant. In addition, upon a change in control of Maker, the
exercisability of options due to vest during the following twelve month period
are automatically accelerated. The outstanding options have an exercise price
ranging from $0.05 to $8.50 per share.

     1999 Non-employee Director Stock Option Plan

     The 1999 Non-employee Director Stock Option Plan (Director Plan) provides
for the grant of nonstatutory stock options to non-employee directors. The
director plan has a term of ten years, unless terminated sooner by the board of
directors. A total of 125,000 shares of common stock have been reserved for
issuance under the Director Plan, plus annual increases such that the total
number of shares subject to issuance shall be (a) 125,000 shares, or (b) a
lesser amount determined by the board of directors.
    

     The Director Plan provides that each non-employee director will
automatically be granted an option to purchase 20,000 shares of common stock on
the date which such person first becomes a non-employee director, unless
immediately prior to becoming a non-employee director, such person was an
employee director of Maker. In addition to this option, each non-employee
director will automatically be granted an option to purchase 15,000 shares on
the date two days after Maker announces its fiscal year-end earnings of each
year, if on such date he or she will have served on the board of directors for
at least the preceding six months. The term of each option shall not exceed ten
years and such shares will vest as determined by the board at the time of
grant. In addition, upon a change in control of Maker, all unvested options
shall immediately vest.

     The exercise price of each option is 100% of the fair market value per
share of the common stock, generally determined with reference to the closing
price of the common stock as reported on the Nasdaq National Market on the last
trading day prior to the date of grant. In the event of a merger of Maker or
the sale of substantially all of its assets, each outstanding option may be
assumed or an equivalent option substituted for by the successor corporation.
Options granted under the director plan must be exercised within three months
of the end of the optionee's tenure as a director of Maker, or within 12 months
after such director's termination by death or disability, but in no event later
than the expiration of the option's term. No option granted under the director
plan is transferable by the optionee other than by will or the laws of descent
and distribution, and each option is exercisable, during the lifetime of the
optionee, only by such optionee.


   
   1999 Stock Incentive Plan

     Maker's 1999 Stock Incentive Plan (1999 Incentive Plan) permits the grant
of stock options, which may be either incentive stock or nonqualified options,
and stock awards. The maximum number of shares of Maker's common stock
available for stock options and stock awards granted under the 1999 Incentive
Plan is 2,600,000 shares plus annual cumulative increases on each January 1
beginning in 2000 equal to (a) 5% of Maker's issued and outstanding common
stock, calculated on a fully diluted basis, or (b) a lesser amount as
determined by the Board of Directors. The maximum number of shares available
under the 1999 Incentive Plan is subject to adjustment for capital changes.
    

     At the discretion of Maker's Board of Directors, the 1999 Incentive Plan
is administered either by the full Board of Directors of Maker or by a
committee consisting of two or more members of Maker's Board of Directors. The
committee has the authority to adopt, amend and rescind such rules and
regulations as, in its opinion, may be advisable in the administration of the
1999 Incentive Plan.

     Options designated as incentive stock options may be granted only to
employees of Maker or any subsidiary. Non-qualified options may be granted to
any officer, employee, consultant or director of


                                       39
                                                                      Management
<PAGE>

Maker or any of its subsidiaries. No option designated as an incentive stock
option shall be granted to any employee of Maker or any subsidiary if such
employee owns, immediately prior to the grant of an option, stock representing
more than 10% of the combined voting power of all classes of stock of Maker or
a parent or a subsidiary, unless the purchase price for the stock under such
option is at least 110% of its fair market value at the time the option is
granted and the option, by its terms is not exercisable more than five years
from the date it is granted.

   
     The maximum number of shares of Maker's common stock with respect to which
an option or options may be granted to any employee in any calendar year shall
not exceed 500,000 shares, taking into account shares subject to options
granted and terminated, or repriced, during such calendar year. Options granted
under the 1999 Incentive Plan will vest as determined by the Board of Directors
or the Committee. Upon a change in control of Maker, the exercisability of
options due to vest during the twelve month period are automatically
accelerated.
    

     The right of any optionee to exercise an option granted to him or her
shall not be assignable or transferable by the optionee other than by will or
the laws of descent and distribution, except that an optionee may transfer
options that are not incentive stock options to the optionee's spouse or
children or to a trust for the benefit of the optionee or the optionee's spouse
or children. Incentive stock options are exercisable during the lifetime of the
optionee only by the optionee.

     An option granted to any employee optionee who ceases to be an employee of
Maker or one of its subsidiaries shall terminate on the last day of the month
in which such optionee ceases to be an employee of Maker or one of its
subsidiaries. If such termination of employment is because of dismissal for
cause or because the employee is in breach of any employment agreement, such an
option will terminate immediately on the date the optionee ceases to be an
employee of Maker or one of its subsidiaries. If such termination of employment
is because the optionee has become permanently disabled, the option shall
terminate on the last day of the twelfth month from the date such optionee
ceases to be an employee. In the event of the death of the optionee, the option
shall terminate on the last day of the twelfth month from the date of death. In
no event shall an option be exercisable after the date upon which it expires by
its terms.

     An option granted to an employee optionee who ceases to be an employee of
Maker or one of its subsidiaries shall be exercisable only to the extent that
the right to purchase shares under such option has accrued and is in effect on
the date such optionee ceases to be an employee of Maker or one of its
subsidiaries. In the event of the death of any optionee, the option granted to
such optionee may be exercised by the estate of such optionee, or by any person
or persons who acquired the right to exercise such option by bequest or
inheritance or by reason of the death of such optionee.

     The Committee may grant, subject to the limitation on the number of shares
of common stock available under the plan, stock awards to employees of and
other key individuals engaged to provide services to Maker and its
subsidiaries. A stock award may be made in stock or denominated in stock
subject to final settlement in cash or stock. Each stock award granted will be
subject to such terms and conditions as the Committee, in its sole discretion,
shall determine and establish.

   1999 Employee Stock Purchase Plan

   
     The Maker 1999 Employee Stock Purchase Plan (Stock Purchase Plan) is
intended to provide a means whereby eligible employees may purchase common
stock of Maker through payroll deductions. Four hundred thousand (400,000)
shares of the common stock of Maker may be issued pursuant to the Stock
Purchase Plan.
    

     All persons employed by Maker and any subsidiaries are eligible to
participate in the Stock Purchase Plan, except (a) persons whose customary
employment is less than twenty hours per week or five months or less per year;
and (b) persons who have been employed by Maker for less than three months on
the first day of the purchase period, with the exception of persons previously
eligible. In addition, persons who are deemed for purposes of Section 423(b)(3)
of the Code, to own stock possessing 5% or more of the total combined voting
power or value of all classes of stock of Maker or a subsidiary are ineligible
to participate in the Stock Purchase Plan. Employment will be treated as
continuing intact while a participating employee is on military leave or other
bona fide leave of absence,


                                       40
Management
<PAGE>

for up to 90 days or for so long as such employee's right to re-employment is
guaranteed by statute or contract, if longer than 90 days.

     The Stock Purchase Plan shall be administered by the Board of Directors or
the Committee appointed from time to time by the Board of Directors. Committee
members shall be ineligible to participate under the Stock Purchase Plan. All
members of the Committee shall serve at the discretion of the Board. The Board
of Directors or the Committee, if one has been appointed, is vested with full
authority to make, administer and interpret such equitable rules and
regulations regarding the Stock Purchase Plan as it may deem advisable.
Determinations by the Board of Directors, or the Committee, as to the
interpretation and operation of the Stock Purchase Plan shall be final and
conclusive.

   
     There shall be four three month purchase periods within each year, with
each commencing on the first day of each three month period beginning February
1, May 1, August 1 and November 1 and continuing through the final day of such
three month period. The initial purchase period shall begin on such date as is
determined by Maker's board of directors. The participating employee authorizes
regular payroll deductions amounting to a full percentage of the participant's
regular compensation as the participant shall designate. Such payroll
deductions cannot amount to less than one percent (1%) nor more than ten
percent (10%) of the participant's regular compensation and cannot exceed
$25,000 per year.
    

     All sums deducted from the regular compensation of participants will be
credited to a stock purchase account established for each participant on the
books of Maker, but prior to use of such funds for the purchase of shares of
Maker's common stock in accordance with the Stock Purchase Plan, Maker may use
such funds for any valid corporate purpose. Maker is under no obligation to pay
interest on funds credited to a participant's stock purchase account in any
event.

   
     The purchase price of shares of Maker common stock under the Stock
Purchase Plan is the lower of (a) eighty-five percent (85%) of the fair market
value of a share of common stock for the first business day of the relevant
purchase period, or (b) eighty-five percent (85%) of such value for the
relevant exercise date. The fair market value on a given day is the mean
between the high and low sales prices of a share of common stock of the Company
on the Nasdaq National Market. Each participating employee receives an option,
effective on the first day of the purchase period, to purchase shares of common
stock on the exercise date, which is the last business day of the purchase
period. The number of shares which a participant may purchase under the option
is the quotient of the aggregate payroll deductions in the purchase period
authorized by the participant, divided by the purchase price. No employee can
be granted an option under the Stock Purchase Plan to purchase shares of
Maker's common stock having a fair market value, as of the date the option to
purchase is granted, in any one calendar year of in excess of $25,000. No
employee can be granted an option in one purchase period for more than 750
shares or 3,000 shares annually, or such other number of shares as determined
from time to time by the Board or the Committee, as the case may be.

     Upon dissolution or liquidation of Maker or a merger or consolidation in
which Maker is not the surviving entity, every option outstanding under the
Stock Purchase Plan shall terminate, and each participant shall be refunded the
sums then in his account.
    


Limitation of Liability; Indemnification of Directors and Officers

   
     In connection with the consummation of this offering, Maker will adopt and
file an Amended and Restated Certificate of Incorporation and Amended and
Restated By-Laws. As permitted by the Delaware General Corporation Law, Maker
has included in its Amended and Restated Certificate of Incorporation a
provision to eliminate the personal liability of its directors for monetary
damages for breach of their fiduciary duties as directors, subject to certain
exceptions. In addition, the Amended and Restated Bylaws of Maker provide that
Maker is required to indemnify its officers and directors under certain
circumstances, including those circumstances in which indemnification would
otherwise be discretionary, and Maker is required to advance expenses to its
officers and directors as incurred in connection with proceedings against them
for which they may be indemnified. Maker has also agreed to indemnify its
directors to the maximum extent permitted by Delaware law pursuant to
agreements with
    


                                       41

such directors and officers. At present, Maker is not aware of any pending or
threatened litigation or proceeding involving a director, officer, employee or
agent of Maker in which indemnification would be required or permitted. Maker
believes that its charter provisions and indemnification agreements are
necessary to attract and retain qualified persons as directors and officers.

Registration Rights Agreement

   
     The registration rights agreement among Maker and the holders of Class B
Convertible Preferred Stock and Class C Convertible Preferred Stock of Maker
provides that such stockholders may require Maker to effect the registration of
shares of common stock held by such stockholders as a result of the conversion
of the preferred stock for sale to the public on three occasions on the earlier
of December 31, 1999 or six months following an initial public offering of
Maker's common stock, subject to limitations on resale. In addition, under the
terms of the registration rights agreement, if Maker proposes to register any
of its shares under the Securities Act, whether for its own account or
otherwise, any holders of Maker's registrable shares party to the registration
rights agreement are entitled to notice of such registration and are entitled
to include their shares therein, subject to specific conditions and
limitations. The holders of registrable shares have waived their right to
include their shares in this offering. All fees, costs, and expenses (other
than underwriting discounts and commissions, transfer taxes and attorneys'
fees) of any registration effected pursuant to the registration rights
agreement will be paid by Maker.


Redemption of Class A Preferred Stock

     All of the outstanding shares of Class A Preferred Stock shall be redeemed
by Maker upon the closing of this offering. In connection with such offering,
officers and directors of Maker and Maker's principal stockholders are holders
of Class A Preferred Stock and will receive amounts payable upon redemption.
    


Issuance of Preferred Stock

   
     During the years 1997 through 1999, Maker issued shares of its Class B
Convertible Preferred Stock and Class C Convertible Preferred Stock. The
purchasers of such shares included Maker's directors, officers and significant
existing stockholders. Such persons received no extra or shared benefit not
shared on a pro rata basis with the other shareholders.
    


Severance Agreement with Michael Rubino

     Maker has entered into a letter agreement with Mr. Rubino which provides
that in the event that his employment is terminated following a change of
control for any reason other than for cause, he will be entitled to receive six
months notice, or six months salary in lieu of such notice. Additionally, upon
a change of control, all unvested options held by Mr. Rubino will vest
immediately.


Other Transactions with Management

     Compensation and Benefits

   
     Maker's executive officers receive compensation, bonuses and other
benefits under employee benefit plan arrangements maintained by Maker and its
subsidiaries. The executive officers participate in such benefit plans under
the same terms generally made available to other similarly situated employees
of Maker or its subsidiary with similar responsibilities and levels of
compensation.
    

     Indemnification Agreements

     Maker has entered into Indemnification Agreements with each of its
   directors. See "Management--

                         DESCRIPTION OF CAPITAL STOCK

   
     Upon completion of the offering, the authorized capital stock of Maker
will consist of 100,000,000 shares of common stock, $.01 par value per share,
of which 17,454,833 shares will be outstanding, and 1,000,000 shares of
preferred stock, $.01 par value per share, none of which will be outstanding.
The following description of the capital stock of Maker and certain provisions
of Maker's Amended and Restated Certificate of Incorporation and Amended and
Restated Bylaws is a summary and is qualified in its entirety by the provisions
of the Amended and Restated Certificate of Incorporation and Amended and
Restated Bylaws which will be adopted by Maker prior to the consummation of the
offering, copies of which have been filed as exhibits to Maker's Registration
Statement of which this prospectus is a part. The following summary assumes the
filing of Maker's Amended and Restated Certificate of Incorporation.
    


Common Stock

   
     Holders of common stock are entitled to one vote for each share held on
all matters submitted to a vote of the stockholders, including the election of
directors. Accordingly, holders of a majority of the shares of common stock
entitled to vote in any election of directors may elect all of the directors
standing for election if they choose to do so. The Amended and Restated
Certificate of Incorporation does not provide for cumulative voting for the
election of directors. Holders of common stock are entitled to receive ratably
such dividends, if any, as may be declared from time to time by the board of
directors out of funds legally available therefor, and shall be entitled to
receive, pro rata, all assets of Maker available for distribution to such
holders upon liquidation. Holders of common stock have no preemptive,
subscription or redemption rights.
    


Preferred Stock

     Maker is authorized to issue "blank check" preferred stock, which may be
issued from time to time in one or more series upon authorization by Maker's
board of directors. The board of directors, without further approval of the
stockholders, is authorized to fix the dividend rights and terms, conversion
rights, voting rights, redemption rights and terms, liquidation preferences,
and any other rights, preferences, privileges and restrictions applicable to
each series of the preferred stock. The issuance of preferred stock, while
providing flexibility in connection with possible acquisitions and other
corporate purposes could, among other things, adversely affect the voting power
of the holders of common stock and, under certain circumstances, make it more
difficult for a third party to gain control of Maker, discourage bids for
Maker's common stock at a premium or otherwise adversely affect the market
price of the common stock. Maker currently has no plans to issue any preferred
stock.


Certain Certificate of Incorporation, Bylaw and Statutory Anti-Takeover
Provisions Affecting Stockholders

     Classified Board

     Maker's board of directors is divided into two classes, each of which,
after a transitional period, will serve for two years, with one class being
elected each year. Removal of a member of the board of directors with or
without cause requires a majority vote of the board of directors or of the
stockholders. A majority of the remaining directors then in office, though less
than a quorum, or the stockholders, are empowered to fill any vacancy on the
board of directors. A majority vote of the stockholders is required to alter,
amend or repeal the foregoing provisions.

     Section 203 of Delaware General Corporation Law

   
     Maker is subject to the "business combination" statute of the Delaware
General Corporation Law. In general, the statute prohibits a publicly held
Delaware corporation from engaging in "business combination" transactions with
any "interested shareholder" for a period of three years after the date of the
transaction in which the person became an "interested shareholder," unless (a)
the transaction is approved by the board of directors prior to the date the
interested shareholder obtained such status, (b) upon consummation of the
transaction which resulted in the shareholder becoming an "interested
shareholder," the "interested shareholder" owned at least 85% of the voting
stock of the corporation
    


                                       46
Description of Capital Stock
<PAGE>

outstanding at the time the transaction commenced, excluding for purposes of
determining the number of shares outstanding those shares owned by persons who
are directors and also officers and employee stock plans in which employee
participants do not have the right to determine confidentially whether shares
held subject to the plan will be tendered in a tender or exchange offer, or (c)
on or subsequent to such date the "business combination" is approved by the
board of directors and authorized at an annual or special meeting of
stockholders by the affirmative vote of at least 662/3% of the outstanding
voting stock which is not owned by the "interested shareholder." A "business
combination" includes mergers, asset sales and other transactions resulting in
a financial benefit to a shareholder. An "interested shareholder" is a person
who, together with affiliates and associates, owns (or within three years, did
own) 15% or more of a corporation's voting stock. By virtue of Maker's decision
not to elect out of the statute's provisions, the statute applies to Maker. No
current stockholders of Maker are "interested stockholders" because their
acquisition of shares was approved by Maker's board of directors. The statute
could prohibit or delay the accomplishment of mergers or other takeover or
change in control attempts with respect to Maker and, accordingly, may
discourage attempts to acquire Maker.

     Director Liability

   
     The Amended and Restated Certificate of Incorporation provides that no
director shall be personally liable to Maker or its stockholders for monetary
damages for breach of fiduciary duty as a director notwithstanding any
provision of law imposing such liability, provided that, to the extent provided
by applicable law, the Amended and Restated Certificate of Incorporation shall
not eliminate the liability of a director for (a) any breach of the director's
duty of loyalty to Maker or its stockholders; (b) acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of law;
(c) acts or omissions in respect of certain unlawful dividend payments or stock
redemptions or repurchases; or (d) any transaction from which such director
derives improper personal benefit. The effect of this provision is to eliminate
the rights of Maker and its stockholders, through stockholders' derivative
suits on behalf of Maker to recover monetary damages against a director for
breach of the fiduciary duty of care as a director, including breaches
resulting from negligent or grossly negligent behavior, except in the
situations described in clauses (a) through (d) above. The limitations
summarized above, however, do not affect the ability of Maker or its
stockholders to seek non-monetary based remedies, such as an injunction or
rescission, against a director for breach of his fiduciary duty nor would such
limitations limit liability under the federal securities laws. Maker's Amended
and Restated Bylaws provide that Maker shall, to the extent permitted by
Delaware General Corporation Law, as amended from time to time, indemnify and
advance expenses to the currently acting and former directors, officers,
employees and agents of Maker or of another corporation, partnership, joint
venture, trust or other enterprise if serving at the request of Maker arising
in connection with their acting in such capacities.
    

     Certain provisions described above may also have the effect of delaying
stockholder actions with respect to certain business combinations and the
election of new members to the board of directors. As such, the provisions
could have the effect of discouraging open market purchases of Maker's common
stock.


   
Registration Rights of Holders of Preferred Stock

     Under the terms of the registration rights agreement among Maker and the
holders of Class B Convertible Preferred Stock and Class C Convertible
Preferred Stock, if Maker proposes to register any of its securities under the
Securities Act following this offering, whether for its own account or
otherwise, holders of approximately 4,554,433 million shares of common stock
are entitled to notice of such registration and are entitled to include their
shares therein, subject to certain conditions and limitations. The holders of
registrable shares also may require Maker to effect the registration of their
"registrable shares" for sale to the public, subject to conditions and
limitations affecting the ability to resell shares. See "Certain
Transactions--Registration Rights Agreement."
    


Transfer Agent and Registrar

   
     The transfer agent and registrar for the common stock will be BankBoston,
N.A.

                        SHARES ELIGIBLE FOR FUTURE SALE

   
     Upon completion of the offering, Maker will have 17,454,833 outstanding
shares of common stock. Of these shares, the 3,500,000 shares offered hereby
(4,025,000 shares if the underwriters' over-allotment option is exercised in
full) will be freely tradable without restriction or further registration under
the Securities Act, unless purchased by "affiliates" of Maker as that term is
defined in Rule 144 described below. The remaining 13,954,833 shares of common
stock outstanding upon closing of the offering are "restricted securities" as
that term is defined in Rule 144. Of the remaining 13,954,833 shares,
13,703,632 shares are subject to lock-up agreements (described below).

     Beginning 90 days after commencement of the offering, approximately
12,660,000 shares will become eligible for sale pursuant to Rule 144 or Rule
701 under the Securities Act ("Rule 701"). Upon expiration of the restricted
periods set forth in the lock-up agreements, an aggregate of 13,727,561 shares
will become immediately eligible for sale subject to the timing, volume, and
manner of sale restrictions of Rule 144. Commencing on January, 2001, all
outstanding shares not owned by affiliates of Maker (currently 1,017,407
shares) will be freely eligible for sale pursuant to Rule 144(k). In addition,
225,777 additional shares of common stock subject to outstanding vested stock
options and 125,000 shares that will be issued upon conversion of a convertible
note could also be sold, subject in some cases to compliance with certain
volume and other limitations as described below.

     In general, under Rule 144, as amended, a person (or persons whose shares
are aggregated) who has beneficially owned shares for at least one year
(including the holding period of any prior owner except an affiliate from whom
such shares were purchased) is entitled to sell in "brokers' transactions" or
to market makers, within any three-month period commencing 90 days after the
date of this prospectus, a number of shares that does not exceed the greater of
(a) one percent of the number of shares of common stock then outstanding,
approximately 174,548 shares immediately after the completion of the offering
or (b) generally, the average weekly trading volume in the common stock during
the four calendar weeks preceding the required filing of a Form 144 with
respect to such sale. Sales under Rule 144 are generally subject to the
availability of current public information about Maker. Under Rule 144(k), a
person who is not deemed to have been an affiliate of Maker at any time during
the 90 days preceding a sale, and who has beneficially owned the shares
proposed to be sold for at least two years (including the holding period of any
prior owner other than an affiliate from whom such shares were purchased), is
entitled to sell such shares without having to comply with the manner of sale,
public information, volume limitation or notice provisions of Rule 144. Under
Rule 701, persons who purchase shares upon exercise of options granted prior to
the effective date of the offering are entitled to sell such shares 90 days
after the effective date of the offering in reliance on Rule 144, without
having to comply with the holding period requirements of Rule 144 and, in the
case of non-affiliates, without having to comply with the public information,
volume limitation or notice provisions of Rule 144.

     Pursuant to the lock-up agreements, all of Maker's officers and directors
and certain stockholders owning upon completion of the offering, in the
aggregate, approximately 13,703,632 shares of common stock, have executed
agreements pursuant to which each has agreed that they will not, directly or
indirectly, offer, pledge, sell or otherwise transfer or dispose of any shares
of common stock or any securities convertible into, or exercisable or
exchangeable for, any shares of common stock or enter into any swap or other
arrangement that transfers all or a portion of the economic consequences
associated with the ownership of any common stock without the prior written
consent of Lehman Brothers Inc. for a period of 150 days subsequent to the date
of this prospectus. Two thirds of such shares shall remain subject to this
lock-up for a period of 180 days subsequent to the date of this prospectus and
one third of such shares shall be subject to this lock-up for a period of 210
days subsequent to the date of this prospectus. Further, holders of outstanding
vested stock options for, in the aggregate, an additional 178,780 shares of
common stock are subject to these lock-up agreements. Maker has agreed not to
sell or otherwise dispose of any shares of common stock, other than options to
purchase common stock under existing stock option or stock purchase plans and
except for the issuance of common stock by Maker as consideration for the
acquisition of businesses for a period of 180 days after the date of this
prospectus without the prior written consent of Lehman Brothers Inc.

     The holders of an aggregate of 4,554,433 shares of common stock or their
transferees are entitled to rights with respect to the registration of such
shares under the Securities Act. See "Description of Capital Stock-Registration
Rights of Holders of Preferred Stock" and "Certain Transactions--
    
Registration Rights Agreement."

   
     Prior to this offering, there has not been any public market for the
common stock. Future sales of substantial amounts of common stock in the public
market could adversely affect the prevailing market prices and impair Maker's
ability to raise capital through the sale of equity securities.

</TABLE>
    

   
     The underwriters will purchase the shares pursuant to an underwriting
agreement with Maker. The underwriters will pay Maker the public offering price
less the underwriting discount specified on the cover page of this prospectus.
Maker estimates that its expenses for this offering will be $1,000,000. Certain
conditions contained in the underwriting agreement must be satisfied before the
underwriters are required to purchase the shares. The underwriters will
purchase either all of the shares or none of them.


     The underwriters have advised Maker that they will offer the shares
directly to the public initially at the public offering price and to selected
dealers, who may include underwriters, at the public offering price less a
selling concession not to exceed $    per share. The underwriters may allow,
and these dealers may reallow, a concession not to exceed $    per share to
certain brokers and dealers. After the initial offering of the shares, the
underwriters may change the public offering price and other selling terms.
    


     The underwriters will offer the shares subject to prior sale, withdrawal,
cancellation or modification of the offer of the shares without notice, and to
their receipt and acceptance of the shares. The underwriters may reject any
order to purchase shares.


   
     Maker has granted the underwriters an option, exercisable not later than
30 days after the date of this prospectus, to purchase up to 525,000 additional
shares at the public offering price less the underwriting discount specified on
the cover page of this prospectus. To the extent that the underwriters exercise
this option, each of the underwriters will have a firm commitment, subject to
conditions, to purchase approximately the same percentage thereof that the
number of shares to be purchased by it shown in the above table bears to
3,500,000 shares, and Maker will be obligated to sell such shares to the
underwriters. The underwriters may exercise such option only to cover
over-allotments. If the underwriters exercise their option in full, the total
public offering price will be $       , the total underwriting discount will be
$       , and the total proceeds to Maker will be $       , before expenses.


     Each of the officers and directors of Maker, and certain shareholders of
Maker, have agreed not to offer, sell or otherwise dispose of any shares of
common stock, directly or indirectly, or engage in hedging transactions with
respect to the common stock, for a period of (a) 210 days with respect to
one-third of the shares, (b) 180 days with respect to two-thirds of the shares
and (c) 150 days with respect to all shares, in each case after the date of
this prospectus, without the prior written consent of Lehman Brothers Inc.
Stockholders who have agreed to this lock-up arrangement hold an aggregate of
13,703,632 shares of common stock and options to purchase an aggregate of
178,780 shares of common stock. Maker has agreed not to sell or otherwise
dispose of any shares of common stock for a period of 180 days, subject to
exceptions such as the issuance of stock as consideration for the acquisition
of businesses. Lehman Brothers Inc. may, in its sole discretion and at any time
without notice, release all or any portion of the shares subject to such
lock-up agreements. See "Shares Eligible for Future Sale."
    


     Prior to the offering, there has been no public market for the shares of
common stock. The initial public offering price will be negotiated by the
underwriters and Maker. The underwriters will consider, among other things and
in addition to prevailing market conditions, Maker's historical performance and
capital structure, estimates of business potential and earning prospects, an
overall assessment of Maker's management and the consideration of the above
factors in relation to market valuation of companies in related businesses.


                                       50
Underwriting
<PAGE>

     Application has been made to have the common stock approved for quotation
on the Nasdaq National Market under the symbol "MAKR."

   
     Maker has agreed to indemnify the underwriters against certain
liabilities, including liabilities under the Securities Act, and to contribute,
under specified circumstances, to payments that the underwriters may be
required to make in respect thereof.

     Until the distribution of the common stock is completed, rules of the
Securities and Exchange Commission may limit the ability of the underwriters
and certain selling group members to bid for and purchase shares of common
stock. As an exception to these rules, the underwriters are permitted to engage
in transactions that stabilize the price of the common stock. Such transactions
may consist of bids or purchases for the purposes of pegging, fixing or
maintaining the price of the common stock.

     If the underwriters create a short position in the common stock in
connection with this offering (i.e., they sell more shares than are set forth
on the cover page of this prospectus), the underwriters may reduce that short
position by purchasing common stock in the open market. The underwriters also
may elect to reduce any short position by exercising all or part of their
over-allotment option.
    

     The underwriters also may impose a penalty bid on certain underwriters and
selling group members. This means that if the underwriters purchase shares of
common stock in the open market to reduce the underwriters' short position or
to stabilize the price of the common stock, they may reclaim the amount of the
selling concession from the underwriters and selling group members who sold
those shares as part of this offering.

     In general, purchases of a security for the purpose of stabilization or to
reduce a syndicate short position could cause the price of the security to be
higher than it might otherwise be in the absence of such purchases. The
imposition of a penalty bid might have an effect on the price of a security to
the extent that it were to discourage resales of the security by purchasers in
an offering.

     Neither Maker nor any of the underwriters makes any representation or
prediction as to the direction or magnitude of any effect that the transactions
described above may have on the price of the common stock. In addition, neither
Maker nor any of the underwriters makes any representation that the
underwriters will engage in such transactions or that such transactions, once
commenced, will not be discontinued without notice.

     Any offers in Canada will be made only pursuant to an exemption from the
requirements to file a prospectus in the relevant province of Canada in which
such sale is made.

     Purchasers of the shares of common stock offered by this prospectus may be
required to pay stamp taxes and other charges under the laws and practices of
the country of purchase, in addition to the public offering price.

     The underwriters have informed Maker that they do not intend to confirm
sales of shares of common stock to any accounts over which they exercise
discretionary authority in excess of 5% of the shares offered by them.


   
                                 LEGAL MATTERS

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS




To the Stockholders and Board of Directors of
Maker Communications, Inc. and subsidiary:


We have audited the accompanying consolidated balance sheets of Maker
Communications, Inc. (a Delaware corporation) and subsidiary as of December 31,
1997 and 1998, and the related consolidated statements of operations,
stockholders' equity (deficit) and cash flows for each of the three years in
the period ended December 31, 1998. These financial statements are the
responsibility of Maker Communications Inc.'s management. Our responsibility is
to express an opinion on these financial statements based on our audits.


We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.


In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of Maker
Communications, Inc. and subsidiary as of December 31, 1997 and 1998, and the
results of their operations and their cash flows for each of the three years in
the period ended December 31, 1998, in conformity with generally accepted
accounting principles.

                   Maker Communications, Inc. and Subsidiary

                   Notes to Consolidated Financial Statements

                (including data applicable to unaudited periods)

   
(1) Nature of Operations
    

     Maker Communications, Inc. (Maker), a Delaware corporation, was founded in
1994. Maker is a fabless semiconductor company that develops and markets
high-performance programmable communications processors, development tools and
application software for use in communications systems equipment. Maker sells
its products to telecommunications and data networking vendors based primarily
in North America.

     In 1998, Maker established a wholly owned subsidiary, Maker Communications
Securities Corporation, which is a qualified Massachusetts securities
corporation.


(2) Significant Accounting Policies

     The accompanying financial statements reflect the application of certain
significant accounting policies as described in this note and elsewhere in the
accompanying consolidated financial statements and notes.

   (a) Principles of Consolidation
     The accompanying consolidated financial statements include the accounts of
Maker and its wholly owned subsidiary. All significant intercompany balances
have been eliminated in consolidation.

   
     (b) Interim Financial Statements
     The accompanying consolidated balance sheet as of March 31, 1999, and the
statements of operations and cash flows for the three months ended March 31,
1998 and 1999, and the statement of stockholders' equity (deficit) for the
three months ended March 31, 1999 are unaudited, but in the opinion of
management, include all adjustments, consisting of normal recurring
adjustments, necessary for a fair presentation of results for these interim
periods. Certain information and footnote disclosures normally included in
financial statements prepared in accordance with generally accepted accounting
principles have been omitted, although Maker believes that the disclosures
included are adequate to make the information presented not misleading. The
results of operations for the three months ended March 31, 1999, are not
necessarily indicative of the results to be expected for the entire fiscal
year.

   (c) Unaudited Pro Forma Presentation
     The unaudited pro forma consolidated balance sheet as of March 31, 1999
and the pro forma net loss per share for the three months ended March 31, 1999
reflect the automatic conversion of all outstanding shares of Class B and Class
C redeemable convertible preferred stock and junior convertible preferred stock
into 7,708,433 shares of common stock, which will occur upon the closing of
Maker's proposed initial public offering and the conversion of the convertible
note payable into 125,000 shares of common stock to occur prior to or upon the
closing of the proposed initial public offering (see Note 6).

   (d) Revenue Recognition
    
     Revenue derived from the sale of processors is recognized upon shipment.
Provisions are made at that time for any applicable warranty costs expected to
be incurred. Revenue from software license agreements is recognized upon
execution of a license agreement and delivery of the software, provided that
the fee is fixed or determinable and deemed collectible by management. Revenue
from software maintenance agreements is recognized ratably over the term of the
maintenance period, which is typically one year. Amounts collected or billed
prior to satisfying the above revenue recognition criteria are reflected as
deferred revenue. Maker recognizes software revenue in accordance with the
provisions of Statement of Position (SOP) No. 97-2, Software Revenue
Recognition.

   
   (e) Net Loss Per Share
     Basic and diluted net loss per common share was determined by dividing net
loss by the weighted average common shares outstanding during the period. Basic
and diluted net loss per share are the same, as
    


                                      F-7

                   Maker Communications, Inc. and Subsidiary

             Notes to Consolidated Financial Statements (Continued)

                (including data applicable to unaudited periods)

   
outstanding common stock options, convertible preferred stock and the
convertible note payable are antidilutive as Maker has recorded a net loss for
all periods presented. Options to purchase a weighted total of 71,585, 491,772,
1,502,553, 1,045,690 and 1,930,358 common shares have been excluded from the
computation of diluted weighted average shares outstanding for the years ended
December 31, 1996, 1997 and 1998 and the three months ended March 31, 1998 and
1999, respectively. Shares of common stock issuable upon the conversion of
outstanding convertible preferred stock and the convertible note payable have
also been excluded for all periods presented. In accordance with the SEC Staff
Accounting Bulletin No. 98, Earnings Per Share in an Initial Public Offering,
the Company determined that there were no nominal issuances of the Company's
common stock prior to the Company's planned initial public offering.

     The calculation of pro forma net loss per common share assumes that all
Class B and Class C redeemable convertible preferred stock and junior
convertible preferred stock had been converted to common stock as of the
issuance date.

   (f) Cost of Revenues

     Cost of revenues includes the cost of purchasing fully assembled, tested
and packaged communications processors from Maker's independent foundries,
production related expenses, warranty, and quality assurance for those
products, as well as costs of personnel associated with supporting Maker's
customers. Cost of revenues also includes software costs, consisting of the
cost of the media on which it is delivered, which amounts are not significant.

   (g) Cash and Cash Equivalents
    

     Cash equivalents consist of short-term, highly liquid investments with
original maturity dates of ninety days or less. Cash equivalents are carried at
cost, which approximates their fair market value.

   
   (h) Inventory
    

     Inventory, which consists of finished goods, is stated at the lower of
cost (first-in, first-out) or market.

   
   (i) Property and Equipment
    

     Property and equipment are stated at cost, net of accumulated depreciation
and amortization. Maker provides for depreciation and amortization using the
straight-line method to allocate the cost of property and equipment over their
estimated useful lives as follows:

                   Maker Communications, Inc. and Subsidiary

             Notes to Consolidated Financial Statements (Continued)

                (including data applicable to unaudited periods)

   
   (j) Software Development Costs
    

     In accordance with Statement of Financial Accounting Standards (SFAS) No.
86, Accounting for the Costs of Computer Software To Be Sold, Leased or
Otherwise Marketed, Maker has evaluated the establishment of technological
feasibility of its various products during the development phase. Due to the
dynamic changes in the market, Maker has concluded that it cannot determine
technological feasibility until the development phase of the project is nearly
complete. The time period during which costs could be capitalized from the
point of reaching technological feasibility until the time of general product
release is very short and, consequently, the amounts that could be capitalized
are not material to Maker's financial position or results of operations.
Therefore, Maker charges all research and development expenses to operations in
the period incurred.


   
   (k) Income Taxes
    

     Maker accounts for income taxes in accordance with the provisions of SFAS
No. 109, Accounting For Income Taxes. This statement requires Maker to
recognize a current tax asset or liability for current taxes payable or
refundable and to record a deferred tax asset or liability for the estimated
future tax effects of temporary differences and carry forwards to the extent
they are realizable. A deferred tax provision or benefit results from the net
change in deferred tax assets and liabilities during the year. A deferred tax
valuation allowance is required if it is more likely than not that all or a
portion of the recorded deferred tax assets will not be realized.


   
   (l) Use of Estimates
    

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


   
   (m) Concentration of Credit Risk

     Maker has no significant off-balance-sheet concentrations of credit risk
such as foreign exchange contracts, option contracts or other foreign hedging
arrangements. Financial instruments that potentially subject Maker to
concentrations of credit risk are principally cash equivalents, accounts
receivable, accounts payable, notes payable and redeemable preferred stock.
Concentration of credit risk with respect to accounts receivable is limited to
certain customers to whom Maker makes substantial sales. Maker performs
periodic credit evaluations of its customers and generally does not require
collateral. Maker has $90,000 in allowances for estimated losses at December
31, 1998 and March 31, 1999.
    


     The following table summarizes the number of customers that individually
comprise greater than 10% of total accounts receivable and their aggregate
percentage of Maker's total accounts receivable.

                (including data applicable to unaudited periods)

   
   (n) Fair Value of Financial Instruments
    

     Financial instruments consist principally of cash and cash equivalents,
accounts receivable, accounts payable, notes payable and redeemable preferred
stock. The estimated fair value of these instruments approximates their
carrying value.

   
   (o) Stock-Based Compensation

     SFAS No. 123, Accounting for Stock-Based Compensation, requires the
measurement of the fair value of stock options or warrants to be included in
the consolidated statement of operations or disclosed in the notes to
consolidated financial statements. Maker has determined that it will account
for stock-based compensation for employees under the intrinsic value-based
method of the Accounting Principles Board Opinion (APB) No. 25, Accounting for
Stock Issued to Employees, and elect the disclosure-only alternative under SFAS
No. 123.

   (p) Comprehensive Income
    

     In June 1997, the Financial Accounting Standards Board (FASB) issued SFAS
No. 130, Reporting Comprehensive Income. Maker does not have any components of
comprehensive income except its reported net loss.

(3) Accrued Expenses

   
     Accrued expenses at December 31, 1997 and 1998 and March 31, 1999

(4) Income Taxes

   
     No provision for federal or state income taxes has been recorded, as Maker
incurred net operating losses for all periods presented. As of December 31,
1998, Maker has net operating loss carryforwards of approximately $8,710,000
available to reduce future federal and state income taxes, if any. Maker also
has available federal tax credits of approximately $330,000 expiring through
2010. If not utilized, these carryforwards expire at various dates through
2018. If substantial changes in Maker's ownership should occur, as defined by
Section 382 of the Internal Revenue Code (the Code), there could be annual
limitations on the amount of carryforwards which can be realized in future
periods. Maker has completed several financings since its inception and has
incurred an ownership change as defined under the Code. The Company does not
believe that this change in ownership will have a material impact on its
ability to utilize its net operating loss and tax credit carryforwards.

     Due to the uncertainty surrounding Maker's ability to utilize its net
operating loss carryforwards, Maker has provided a full valuation allowance
against its otherwise recognizable deferred tax asset at December 31, 1997 and
1998.
    

(5) Notes Payable to a Bank

   (a) Working Capital Line of Credit

   
     On February 18, 1997, Maker entered into a working capital line of credit
of $1,000,000 with a bank. On May 12, 1998 and on February 3, 1999, Maker
entered into loan modification agreements with the bank whereby the working
capital line of credit was increased to $2,000,000 and $2,500,000,
respectively. Borrowings bear interest at the bank's prime rate (7.75% at
December 31, 1998) plus .25%. The line of credit is collateralized by
substantially all assets of Maker. The line of credit expires in February 2000.
Maker had no borrowings under the working capital line of credit as of December
31, 1998 and March 31, 1999.
    

   (b) Capital Expenditure Line of Credit

   
     Maker has borrowings under a modified equipment line of credit facility
with the same bank. Borrowings are payable over a 30 to 39 month period and
bear interest at the bank's prime rate (7.75% at December 31, 1998) plus .25%
to prime plus 1.0%. In 1999, Maker borrowed an additional $450,000 under its
existing equipment line of credit facility. On February 3, 1999, Maker entered
into a loan modification agreement with the bank that provided Maker with an
additional $1,000,000 of borrowing availability under its capital expenditure
line of credit. As of March 31, 1999, Maker had $1,000,000 available under the
modified equipment line of credit. All borrowings under the equipment line of
credit are collateralized by substantially all assets of Maker. Under these
agreements, Maker is required to comply with certain restrictive covenants. As
of December 31, 1998 and March 31, 1999, Maker was in compliance with all such
covenants.

     The maturities under the capital expenditure lines of credit as of March
31, 1999 are as follows:

(6) Convertible Note Payable

     In July 1998, Maker issued a $500,000 convertible note payable to LSI
Logic Corporation (LSI) which accrues interest at an annual rate of 6.5%. All

A redeemable preferred stock at $1.605 per share in exchange for the conversion
of a note payable to a stockholder in the amount of approximately $34,000.

stock, Class C redeemable convertible preferred stock and common stock. The
Class A redeemable preferred stock has a liquidation preference of $1.605 per
share plus all declared but unpaid dividends. As of December 31, 1998 and March

per share price of at least $6.75 and resulting in aggregate proceeds to Maker
of at least $20,000,000. These shares have dividend rights superior to junior
convertible preferred stock and common stock and similar to the Class C
redeemable convertible preferred stock. The Class B redeemable convertible
preferred stock has a liquidation preference of $3.00 per share plus all
declared but unpaid dividends. As of December 31, 1998 and March 31, 1999, the

(8) Stockholders' Equity (Deficit)

   (a) Common Stock

   
     In 1998, Maker increased the authorized shares of common stock to
17,174,670. Upon completion of the proposed initial public offering, the
authorized capital stock will be 100,000,000 shares of common stock and
1,000,000 shares of preferred stock. As of March 31, 1999, Maker had reserved
3,416,575, 1,137,858 and 3,154,000 shares of common stock for the conversion of
Class B convertible preferred stock, Class C convertible preferred stock and
junior convertible preferred stock, respectively.
    

   (b) Junior Convertible Preferred Stock

     In 1996, Maker authorized 4,019,654 shares of junior convertible preferred
stock $0.01 par value. In September 1996, each outstanding share of $.01 par
value common stock, totaling 4,019,654 shares, was exchanged for one share of
junior convertible preferred stock. In October 1996, Maker repurchased and
retired 865,654 shares of junior convertible preferred stock.

   
     The junior convertible preferred stock is subordinate to Class A

stock in regard to liquidation. Junior convertible preferred stock is
optionally redeemable by Maker at a price of $0.005 per share subsequent to the
redemption of the Class A redeemable preferred stock. Each share of junior
convertible preferred stock may, at the option of the holder, be converted to
one share of common stock, as adjusted for certain events.
    

     Conversion will occur automatically upon the completion of an initial
public offering at a per share price of at least $6.75 and resulting in
aggregate proceeds to Maker of at least $20,000,000. Voting rights are provided
to junior convertible preferred stock in proportion to the number of shares of
common stock that would be received upon conversion.

   
     (c) Stock Plans

   1996 Option Plan

     During 1996, the Board of Directors approved the 1996 Stock Option Plan
(the 1996 Plan). The Board of Directors has reserved 3,876,000 shares of common
stock for issuance under the 1996 Plan. Options issued under the 1996 Plan may
be either incentive stock options or nonqualified stock options at the
discretion of the Board of Directors. Options may be granted to key employees,
officers, consultants and advisers of Maker. Options expire up to 10 years from
the date of grant or as determined by the Board of Directors. Options vest over
a term to be established by the Board of Directors at the date of grant. Under
the 1996 Plan, at the option of the Board of Directors, certain option grants
may be immediately exercisable but subject to a right of repurchase at cost at
the option of the Board of Directors, pursuant to the vesting schedule of such
grant. In addition, upon a change in control of Maker, as defined, the
exercisability of options due to vest during the following twelve month period
are automatically accelerated. Upon the effectiveness of the Company's 1999
Incentive Stock Plan, no further options shall be granted under the 1996 Plan.

   1999 Incentive Stock Plan

     In April 1999, the Board of Directors approved the 1999 Incentive Stock
Plan (1999 Plan) permitting the grant of stock options, which may be either
incentive stock or nonqualified options and stock awards. This plan will be
effective upon the successful closing of Maker's proposed initial public
offering. The maximum number of shares of Maker's common stock available for
stock options and stock awards granted under the 1999 Plan is 2,600,000 plus
annual cumulative increases on each January 1, beginning in 2000 equal to (a)
5% of Maker's issued and outstanding common stock calculated on a fully diluted
basis or (b) a lesser amount as determined by the Board of Directors.

     Options designated as incentive stock options may be granted only to
employees of Maker. Non-qualified options may be granted to any officer,
employee, consultant or director of Maker. No option designated as an incentive
stock option shall be granted to any employee of Maker or any subsidiary if
such employee owns, immediately prior to the grant of an option, stock
representing more than 10% of the combined voting power of all classes of stock
of Maker, unless the purchase price for the stock under such option is at least
110% of its fair market value at the time the option is granted and the option,
by its terms is not exercisable more than five years from the date it is
granted.

     The maximum number of shares of Maker's common stock with respect to which
an option or options may be granted to any employee in any calendar year shall
not exceed 500,000 shares, taking into account shares subject to options
granted and terminated, or repriced, during such calendar year. Options granted
under the 1999 Incentive Plan will vest as determined by the Board of
Directors. Upon a change in control of Maker, the exercisability of options due
to vest during the twelve month period following the change in control are
automatically accelerated.

     Director Option Plan

     In January 1999, the Board of Directors adopted a Director Option Plan
(Director Plan) pursuant to which 125,000 shares of common stock have been
reserved for future issuance, plus annual increases such
    


                                      F-14
<PAGE>

                   Maker Communications, Inc. and Subsidiary

             Notes to Consolidated Financial Statements (Continued)

                (including data applicable to unaudited periods)

   
that the total number of shares subject to issuance shall be (i) 125,000 on
January 1 of each year, or (ii) a lesser amount determined by the Board of
Directors. The Director Plan provides that each non employee director will
automatically be granted an option to purchase 20,000 shares on the date which
such person first becomes a non employee director. In addition, each non
employee director will automatically be granted an option to purchase 15,000
shares on the date two days after Maker announces its fiscal year-end earnings
of each year, if on such date that director will have served on the Board of
Directors for at least the preceding six months. Each option will have a term
of up to 10 years and will vest over a term determined by the Board of
Directors at the time of grant. In addition, upon a change in control of Maker,
as defined in the Director Plan, all unvested options shall vest immediately.
Options granted to directors will be accounted for in accordance with SFAS No.
123 based upon the guidance provided in the exposure draft dated March 31, 1999
for the proposed interpretation, Accounting for Certain Transactions Involving
Stock Compensation, of APB No. 25. The fair value of directors' grants will be
measured and included in the consolidated statement of operations.

     1999 Employee Stock Purchase Plan

     In April 1999, the Board of Directors approved the Maker 1999 Employee
Stock Purchase Plan (the Stock Purchase Plan). This plan will be effective upon
the successful closing of Maker's proposed initial public offering. The Stock
Purchase Plan is intended to provide a means whereby eligible employees may
purchase, on a quarterly basis, common stock of Maker through payroll
deductions. Such payroll deductions cannot amount to less than 1% nor more than
10% of the participant's regular compensation and cannot exceed $25,000 or
3,000 shares per year. The purchase price of shares of Maker common stock under
the Stock Purchase Plan is the lower of 85% of the fair market value of a share
of common stock for the first business day of the relevant purchase period or
85% of such value for the relevant exercise date. 400,000 shares of Maker
common stock have been reserved for issuance under the Stock Purchase Plan.
Maker will account for the Stock Purchase Plan in accordance with APB No. 25
and accordingly, no compensation cost will be recognized under the Stock
Purchase Plan. Maker will elect the "disclosure only" alternative under SFAS
No. 123.

     The following table summarizes option activity under the stock plans:

Plan. Maker may make discretionary profit-sharing contributions to the Plan.
Participants vest in Maker's contributions ratably over five years. No
discretionary contributions were made in 1996, 1997 or 1998 or the three months
ended March 31, 1999.

ITEM 17. UNDERTAKINGS

     The undersigned registrant hereby undertakes to provide to the
underwriters at the closing specified in the underwriting agreement,
certificates in such denomination and registered in such names as required by
the underwriters to permit proper delivery to each purchaser.

     The undersigned registrant hereby undertakes that: (1) For purposes of
determining any liability under the Securities Act, the information omitted
from the form of prospectus filed as part of this registration statement in
reliance upon Rule 430A and contained in a form of prospectus filed by the
registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act
shall be deemed to be part of this registration statement as of the time it was
declared effective; and (2) For the purpose of determining any liability under
the Securities Act, each post-effective amendment that contains a form of
prospectus shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereto.

     Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
registrant pursuant to provisions described in Item 14 above, or otherwise, the
registrant has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by
such director, officer or controlling person in connection with the securities
being registered, the registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Act and will be governed by the final
adjudication of such issue.

                              AMENDED AND RESTATED

                          CERTIFICATE OF INCORPORATION

                                       OF

                           MAKER COMMUNICATIONS, INC.


     Maker Communications, Inc., a corporation organized and existing under the
laws of the State of Delaware (the "Corporation"), DOES HEREBY CERTIFY as
follows:

     The date of filing of its original Certificate of Incorporation with the
Secretary of State of the State of Delaware was September 19, 1996.

     The Board of Directors of the Corporation, by unanimous written consent,
duly adopted resolutions setting forth the Amended and Restated Certificate of
Incorporation herein contained, declaring its advisability and directing that
such Amended and Restated Certificate of Incorporation be submitted to the
holders of the issued and outstanding capital stock for approval in accordance
with the applicable provisions of Sections 242 and 245 of the General
Corporation Law of the State of Delaware and the Corporation's Certificate of
Incorporation, as previously amended.

     The Amended and Restated Certificate of Incorporation was duly adopted,
after having been declared advisable by the Board of Directors of the
Corporation by the stockholders of the Corporation by written consent in
accordance with Sections 228 and 242 of the General Corporation Law of the State
of Delaware, and prompt written notice of the taking of the action without a
meeting by less than unanimous written consent has been given in accordance with
section 228(d) to the stockholders who did not consent in writing.

     The text of the Amended and Restated Certificate of Incorporation of the
Corporation, as restated and amended (herein called the "Restated Certificate of
Incorporation") shall read in its entirety as follows:

     FIRST: The name of the Corporation shall be:

            MAKER COMMUNICATIONS, INC.

     SECOND: The registered office of the Corporation in the State of Delaware
is located at 1209 Orange Street, in the City of Wilmington, County of New
Castle, 19801, and its registered agent at such address is The Corporation Trust
Company.

     THIRD: The purpose or purposes of the Corporation shall be to engage in any
lawful act or activity for which corporations may be organized under the General
Corporation Law of the State of Delaware.

<PAGE>

     FOURTH: The total number of shares of stock which the Corporation shall
have authority to issue is 101,000,000 shares, which shares shall be divided
into two classes consisting of: (i) 100,000,000 shares of Common Stock (with
$.01 par value per share) ("Common Stock") and (ii) 1,000,000 shares of
Preferred Stock (with $.01 par value per share) ("Blank Check Preferred Stock").

     The designations and the powers, preferences and rights, and the
qualifications, limitations or restrictions of the Common Stock and the
Preferred Stock shall be as follows:


A.   COMMON STOCK

     1. Voting Rights. Except as otherwise required by law or this Amended and
Restated Certificate of Incorporation, each holder of Common Stock shall have
one vote in respect of each share of Common Stock held by him of record on the
books of the Corporation for the election of directors and on all matters
submitted to a vote of stockholders of the Corporation.

     2. Dividends. The holders of shares of Common Stock shall be entitled to
receive, when and if declared by the Board of Directors, out of the assets of
the Corporation which are by law available therefor, dividends payable either in
cash, in property or in shares of capital stock, subject, however, to the
limitations contained in Part B below.

     3. Dissolution, Liquidation or Winding Up. After distribution in full of
the preferential amount, if any, to be distributed to the holders of series of
the Blank Check Preferred Stock (in accordance with the relative preferences
among such series) in the event of involuntary liquidation, distribution,
dissolution or winding-up, of the Corporation, the holders of the Common Stock
shall be entitled to receive all of the remaining assets of the Corporation,
tangible and intangible, or whatever kind available for distribution to
stockholders, ratably in proportion to the number of shares of Common Stock held
by them respectively.


B.   BLANK CHECK PREFERRED STOCK

     1. Issuance. Shares of Blank Check Preferred Stock may be issued from time
to time in one or more series as may from time to time be determined by the
Board of Directors, each of said series to be distinctly designated. All shares
of any one series of the Blank Check Preferred Stock shall be alike in every
particular, except that there may be different dates from which dividends, if
any, thereon shall be cumulative, if made cumulative. The voting powers, if any,
and the designations, relative preferences, participating, optional or other
special rights or privileges of each such series, and the qualifications,
limitations or restrictions thereof, if any, may differ from those of any and
all other series at any time outstanding.

                                      -2-
<PAGE>

     2. Authority of the Board of Directors. The Board of Directors is
authorized, subject to limitations prescribed by law and the provisions of this
Article FOURTH, to provide for the issuance of the shares of the Blank Check
Preferred Stock in series, and by filing a certificate pursuant to the
applicable law of the State of Delaware, to establish from time to time the
number of shares to be included in each such series, and to fix in the
resolution or resolutions providing for the issue of such stock adopted by the
Board of Directors of the Corporation the voting powers, if any, and the
designations, relative preferences, participating, optional or other special
rights or privileges, and the qualifications, limitations or restrictions of
such series, including, but without limiting the generality of the foregoing,
the following:

        (a) The distinctive designation of, and the number of shares of the
        Blank Check Preferred Stock which shall constitute such series. The
        designation of a series of preferred stock need not include the words
        "preferred" or "preference" and may be designated "special" or other
        distinctive term. Unless otherwise provided in the resolution issuing
        such series, the number of shares of any series of the Blank Check
        Preferred Stock may be increased or decreased (but not below the number
        of shares thereof then outstanding) by the Board of Directors in the
        manner prescribed by law;

        (b) The rate and times at which, and the terms and conditions upon
        which, dividends, if any, on the Blank Check Preferred Stock of such
        series shall be paid, the extent of the preference or relation, if any,
        of such dividends to the dividends payable on any other class or
        classes, or series of the same or other classes of stock and whether
        such dividends shall be cumulative or non-cumulative and, if cumulative,
        the date from which such dividends shall be cumulative;

        (c) Whether the series shall be convertible into, or exchangeable for,
        at the option of the holders of the Blank Check Preferred Stock of such
        series or the Corporation or upon the happening of a specified event,
        shares of any other class or classes or any other series of the same or
        any other class or classes of stock of the Corporation, and the terms
        and conditions of such conversion or exchange, including provisions for
        the adjustment of any such conversion rate in such events as the Board
        of Directors shall determine;

        (d) Whether or not the Blank Check Preferred Stock of such series shall
        be subject to redemption at the option of the Corporation or the holders
        of such series or upon the happening of a specified event, and the
        redemption price or prices and the time or times at which, and the terms
        and conditions upon which, the Blank Check Preferred Stock of such
        series may be redeemed;

                                      -3-
<PAGE>

        (e) The rights, if any, of the holders of the Blank Check Preferred
        Stock of such series upon the voluntary or involuntary liquidation,
        merger, consolidation, distribution or sale of assets, dissolution or
        winding-up, of the Corporation;

        (f) The terms of the sinking fund or redemption or purchase account, if
        any, to be provided for the Blank Check Preferred Stock of such series;
        and

        (g) Subject to subparagraph 5 of Paragraph C hereof, whether such series
        of the Blank Check Preferred Stock shall have full, limited or no voting
        powers including, without limiting the generality of the foregoing,
        whether such series shall have the right, voting as a series by itself
        or together with other series of the Blank Check Preferred Stock or all
        series of the Blank Check Preferred Stock as a class, to elect one or
        more directors of the Corporation if there shall have been a default in
        the payment of dividends on any one or more series of the Blank Check
        Preferred Stock or under such other circumstances and on such conditions
        as the Board of Directors may determine.


C.   OTHER PROVISIONS.

     1. No holder of any of the shares of any class or series of stock or of
options, warrants or other rights to purchase shares of any class or series of
stock or of other securities of the Corporation shall have any preemptive right
to purchase or subscribe for any unissued stock of any class or series or any
additional shares of any class or series to be issued by reason of any increase
of the authorized capital stock of the Corporation of any class or series, or
bonds, certificates of indebtedness, debentures or other securities convertible
into or exchangeable for stock of the Corporation of any class or series, or
carrying any right to purchase stock of any class or series, but any such
unissued stock, additional authorized issue of shares of any class or series of
stock or securities convertible into or exchangeable for stock, or carrying any
right to purchase stock, may be issued and disposed of pursuant to resolution of
the Board of Directors to such persons, firms, corporations or associations
(including such holders or others) and upon such terms as may be deemed
advisable by the Board of Directors in the exercise of its sole discretion.

     2. The relative powers, preferences and rights of each series of the Blank
Check Preferred Stock in relation to the powers, preferences and rights of each
other series of the Blank Check Preferred Stock shall, in each case, be as fixed
from time to time by the Board of Directors in the resolution or resolutions
adopted pursuant to authority granted in Paragraph B hereof. The consent, by
class or series vote or otherwise, of the holders of such of the series of the
Blank Check Preferred Stock as are from time to time outstanding shall not be
required for the issuance by the Board of Directors of any other series of the
Blank Check Preferred Stock whether or not the powers, preferences and rights of

                                      -4-
<PAGE>

such other series shall be fixed by the Board of Directors as senior to, or on a
parity with, the powers, preferences and rights of such outstanding series, or
any of them; provided, however, that the Board of Directors may provide in the
resolution or resolutions as to any series of the Blank Check Preferred Stock
adopted pursuant to Paragraph B hereof, the conditions, if any, under which the
consent of the holders of a majority (or such greater proportion as shall be
fixed therein) of the outstanding shares of such series shall be required for
the issuance of any or all other series of the Blank Check Preferred Stock.

     3. Subject to the provisions of subparagraph 2 of this Paragraph C, shares
of any series of the Blank Check Preferred Stock may be issued from time to time
as the Board of Directors of the Corporation shall determine and on such terms
and for such consideration as shall be fixed by the Board of Directors.

     4. Shares of authorized Common Stock may be issued from time to time as the
Board of Directors of the Corporation shall determine and on such terms and for
such consideration as shall be fixed by the Board of Directors.

     5. The number of authorized shares of Common Stock and of the Blank Check
Preferred Stock, without a class or series vote, may be increased or decreased
from time to time (but not below the number of shares thereof then outstanding)
by the affirmative vote of the holders of a majority of the stock of the
Corporation entitled to vote thereon.

     FIFTH:

     A. Number, Election and Terms of Directors. The number of directors shall
be fixed from time to time exclusively by the Board of Directors pursuant to a
resolution adopted by the Board of Directors. The Directors of the Corporation
shall be divided into two classes: Class I and Class II. Each class shall
consist, as nearly as may be possible, of one-half of the whole number of the
Board of Directors. If the Board of Directors is not evenly divisible by two,
the Board of Directors shall determine the number of Directors to be elected to
each class. The initial members of Class I shall be Rob Soni and Roger Evans and
they shall hold office for a term to expire at the Annual Meeting of the
Stockholders to be held in 2000; the initial members of Class II shall be
William Guidice Louis Tomasetta and Paul Low and they shall hold office for a
term to expire at the Annual Meeting of the Stockholders to be held in 2001, and
in the case of each class, until their respective successors are duly elected
and qualified. At each annual election held commencing with the annual election
in 2000, the Directors elected to succeed those whose terms expire shall be
identified as being of the same class as the Directors they succeed and shall be
elected to hold office for a term to expire at the second Annual Meeting of the
Stockholders after their election, and until their respective successors are
duly elected and qualified. If the number of Directors changes, any increase or
decrease in Directors shall be apportioned among the classes so as to maintain
all classes as equal in number as possible, and any additional Director elected
to any class shall hold office for a term which shall coincide with the terms of
the other Directors in such class and until his successor is duly elected and
qualified.

                                      -5-
<PAGE>

     B. Removal. Any Director or the entire Board of Directors may be removed
with or without cause by the holders of a majority of the shares then entitled
to vote at an election of Directors, or a majority vote of the Board of
Directors.

     C. Amendment, Repeal or Alteration. Notwithstanding any other provisions of
the Restated Certificate of Incorporation or the Restated By-Laws of the
Corporation or the fact that a lesser percentage may be specified by law, the
affirmative vote of the holders of greater than fifty percent (50%) of the
combined voting power of the outstanding stock of the Corporation entitled to
vote generally in the election of Directors, voting together as a single class,
shall be required to amend, alter, adopt any provision inconsistent with or to
repeal this Article FIFTH.

     SIXTH: The Corporation hereby affirmatively elects in this Restated
Certificate of Incorporation to be governed by Section 203 of the General
Corporation Law of Delaware.

     SEVENTH: Whenever a compromise or arrangement is proposed between the
Corporation and its creditors or any class of them and/or between the
Corporation and its stockholders or any class of them, any court of equitable
jurisdiction within the State of Delaware may, on the application in a summary
way of the Corporation or of any creditor or stockholder thereof or on the
application of any receiver or receivers appointed for the Corporation under the
provisions of section 291 of Title 8 of the Delaware Code or on the application
of trustees in dissolution or of any receiver or receivers appointed for the
Corporation under the provisions of section 279 of Title 8 of the Delaware Code,
order a meeting of the creditors or class of creditors, and/or of the
stockholders or class of stockholders of the Corporation, as the case may be, to
be summoned in such manner as the said court directs. If a majority in number
representing three-fourths in value of the creditors or class of creditors,
and/or of the stockholders or class of stockholders of the Corporation, as the
case may be, agree to any compromise or arrangement and to any reorganization of
the Corporation as a consequence of such compromise or arrangement, the said
compromise or arrangement and the said reorganization shall, if sanctioned by
the court to which the said application has been made, be binding on all the
creditors or class of creditors, and/or on all the stockholders or class of
stockholders, of the Corporation, as the case may be, and also on the
Corporation.

     EIGHTH: No director shall be personally liable to the Corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director
notwithstanding any provision of law imposing such liability; provided that, to
the extent provided by applicable law, this provision shall not eliminate the
liability of a director (i) for any breach of the director's duty of loyalty to
the Corporation or its stockholders, (ii) for acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of law,
(iii) under Section 174 of the General Corporation Law of Delaware, or (iv) for
any transaction from which the director derived an improper personal benefit. No
amendment to or repeal of this provision shall apply to or have any effect on
the liability or alleged liability of any

                                      -6-
<PAGE>

director for or with respect to any acts or omissions of such director occurring
prior to such amendment or repeal.

     NINTH: In furtherance and not in limitation of the powers conferred by the
laws of the State of Delaware.

     A. The Board of Directors of the Corporation is expressly authorized to
adopt, amend, or repeal the By-laws of the Corporation.

     B. Elections of directors need not be by written ballot unless the By-laws
of the Corporation shall so provide.

     C. The books of the Corporation may be kept at such place within or without
the State of Delaware as the By-laws of the Corporation may provide or as may be
designated from time to time by the Board of Directors of the Corporation.

     TENTH: Except as otherwise stated elsewhere in this Restated Certificate of
Incorporation, the Corporation reserves the right to amend or repeal any
provision contained in this Restated Certificate of Incorporation, in the manner
now or hereafter prescribed by statute, and all rights conferred upon a
stockholder herein are granted subject to this reservation.

     ELEVENTH: The Corporation is to have perpetual existence.

     caused by any change in  ownership or new  construction),  now or hereafter

     within  the  meaning  of the  terms  "Property  Tax" or  "Property  Taxes".

specified in the Basic Lease  Information.  Landlord and Tenant acknowledge that

Premises,  as specified in the Basic Lease  Information,  by the total  Rentable

     2.   TERM.

     The term of this Lease shall  commence  and,  unless  sooner  terminated as
hereinafter provided, shall end on the dates respectively specified in the Basic
Lease  Information.  If Landlord,  for any reason  whatsoever  beyond  Landlords
reasonable  control,  cannot deliver possession of the Premises to Tenant at the
commencement  of the term,  this Lease shall not be void or voidable,  nor shall
Landlord be liable to Tenant for any loss or damage resulting therefrom, but  in
that event,  rental shall be waived for the period between the  commencement  of
the term and the time when Landlord can deliver possession.

     3.   RENTAL.

     (a)  Tenant  shall pay to  Landlord  throughout  the term of this  Lease as
rental for the Premises the sum specified in the Basic Lease  Information as the
Base Rent,  provided that the rental  payable during each calendar year shall be
the Base Rent,  increased by Tenants Percentage Share of the total dollar amount
above or increase in, if any, Operating Expenses paid or incurred by Landlord in
such  year over the Base  Operating  Expenses,  and also  increased  by  Tenants
Percentage  Share of the  total  dollar  amount  above or  increase  in, if any.
Property Taxes paid by Landlord in such year over the Base Property  Taxes.  The
increased rental due pursuant to this paragraph 3(a) is hereinafter  referred to
as "Escalation Rent."

     (b) Rental shall be paid to Landlord on or before the first day of the term
hereof  and on or before  the first  day of each and every  successive  calendar
month  thereafter  during the term  hereof.  In the event the term of this Lease
commences on a day other than the first day of a calendar month or ends on a day
other than the last day of a calendar  month,  the monthly  rental for the first
and last fractional months of the term hereof shall be appropriately prorated.

     (c)  All  sums  of  money  due  to  Landlord   hereunder  not  specifically
characterized as rental shall constitute additional rent, and if any such sum is
not paid at the time provided in this Lease, it shall nonetheless be collectible
as additional rent at any time thereafter,  including, without limitation on the
date on which the next  installment of rental is due.  Nothing  contained herein
shall be deemed to suspend or delay the  payment of any sum of money at the time
it becomes due and payable hereunder, or to limit any other remedy of Landlord.

     (d) Tenant hereby  acknowledges  that late payment by Tenant to Landlord of
rent and other  sums  due  hereunder  will  cause  Landlord  to incur  costs not
contemplated  by this  Lease,  the exact  amount of which will be  difficult  to
ascertain. Such costs include, but are not limited to, processing and accounting
charges,  and  late charges which may be imposed on Landlord by the terms of any
trust deed covering the Premises. Accordingly, if any installment of rent or any
other sums due from Tenant shall not be received by Landlord  when due or in the
time period provided herein. Tenant shall pay to Landlord a late charge equal to

from the date due until paid at the lower of (i) the rate of the Prime Rate plus

     payments for such calendar year previously  made by Tenant,  Landlord shall
     credit  such  excess  against  the next  payment of rental due from  Tenant
     hereunder.  If Landlord's  statement  discloses  that Tenant owes an amount
     that is more than the estimated  payments for such calendar year previously
     made by Tenant,  Tenant shall pay the deficiency to Landlord within 30 days
     after delivery of the statement

     concluded  or be  deducted  from  Tenant's  next  payment's)  of  rent.  In
     addition,  if the statement  overstates actual Operating  Expenses and Real

until (i) all  required  governmental  approvals  and  permits  shall  have been
obtained,  (ii) all requirements  regarding insurance imposed by this Lease have
been  satisfied,  (iii) Tenant shall have given  Landlord at lease five business
days  prior  written  notice  of its  intention  to  commence  such work so that
Landlord may post and file notices of non-responsibility,  and (iv) if requested
by Landlord,  Tenant shall have  obtained  contingent  liability  and broad form
builder's risk insurance in an amount satisfactory to Landlord in its reasonable
discretion  to cover any perils  relating  to the  proposed  work not covered by
insurance  carried by Tenant  pursuant to Paragraph 20. In no event shall Tenant
make any  modification,  alterations  or  improvements  whatsoever to the Common
Areas or the  exterior  or  structural  components  of the  Building  including,
without  limitation,  any cuts or  penetrations  in the floor,  roof or exterior
walls  of the  Premises.  As used  in this  Article,  the  term  "modifications,
alterations  and/or  improvements"  shall  include,   without  limitation,   the
installation  of additional  electrical  outlets,  overhead  lighting  fixtures,
drains, sinks, partitions, doorways, or the like.

     (b) All  modifications,  alterations and improvements  made or added to the
Premises by Tenant (other than Tenant's inventory, equipment, movable furniture,
wall decorations and trade fixtures) shall be deemed real property and a part of
the Premises, but shall remain the property of Tenant during the Lease. Any such
modifications, alterations or improvements, once completed, shall not be altered
or removed from the Premises  during the Lease Term without  Landlord's  written
approval  first obtained in accordance  with the  provisions of Paragraph  14(a)
above.  At the  expiration  or  sooner  termination  of  this  Lease,  all  such
modifications,  alterations  and  improvements  other than  Tenant's  inventory,
equipment,  movable  furniture,  wall  decorations  and  trade  fixtures,  shall
automatically  become the  property  of  Landlord  and shall be  surrendered  to
Landlord as part of the  Premises as required  pursuant to  Paragraph  7, unless
Landlord shall require Tenant to remove any of such  modifications,  alterations
or  improvements in accordance with the provisions of Paragraph 7, in which case
Tenant shall so remove same.  Landlord  shall have no  obligations  to reimburse
Tenant for all or any  portion  of the cost or value of any such  modifications,
alterations  or  improvements  so surrendered  to Landlord.  All  modifications,
alterations or improvements which are installed or constructed on or attached to
the  Premises  by Landlord  and/or at  Landlord's  expense  shall be deemed real
property  and a part of the  Premises  and shall be  property of  Landlord.  All
lighting,  plumbing,  electrical,  heating,  ventilating  and  air  conditioning
fixtures,  partitioning,  window  coverings,  wall coverings and floor coverings
installed by Tenant shall be deemed  improvements  to the Premises and not trade
fixtures of Tenant.

     (c) Tenant shall make all  modifications,  alterations and  improvements to
the  Premises,  at its sole cost,  that are  required  by any Law because of (i)
Tenant's use or occupancy of the Premises, the Building, the Common Areas or the
Property,  (ii) Tenant's application for any permit or governmental approval, or
(iii) Tenant's  making of any  modifications,  alterations or improvements to or
within the Premises.  If Landlord  shall,  at any time during the Lease Term, be
required by any governmental authority to make any modifications, alterations or
improvements  to the Building or the Property,  the cost incurred by Landlord in
making such modifications,  alterations or improvements, including interest at a
rate  equal to the  greater  of (a) 12%,  or (b) the sum of that rate  quoted by
Wells Fargo  Bank,  N.T. & S.A.  from time to time as its prime  rate,  plus two
percent (2%) ("Wells  Prime Plus Two"),  shall be amortized by Landlord over the
useful life of such modifications, alterations or improvements, as determined in
accordance  with  generally  accepted  accounting  principles,  and the  monthly
amortized  cost  of  such  modifications,  alterations  and  improvements  as so
amortized shall be included in Operating Expenses.

     15. REPAIRS.

     By entry hereunder Tenant accepts the Premises as being in the condition in
which Landlord is obligated to deliver the Premises.  Tenant shall, at all times
during the term hereof, and at Tenant's sole cost and expense, keep the Premises
in good  condition and repair,  ordinary wear and tear,  damage thereto by fire,
earthquake, act of God or the elements excepted. Tenant hereby waives all rights
to make  repairs at the  expense of  Landlord  or in lieu  thereof to vacate the
Premises.  Tenant shall at the end of the term hereof  surrender to Landlord the
Premises and all alterations  thereto in the good and clean condition,  ordinary
wear  and tear  and  damage  by  fire,  earthquake,  act of God or the  elements
excepted.  Landlord has no obligation and has made no promise to alter, remodel,
improve, repair, decorate or paint the Premise or any part



                                       8.

thereof,  except  as  specifically  hereto  set  forth.  No  representations  or
warranties  respecting  the  condition of the Premises or the Building have been
made by Landlord to Tenant, except as specifically herein set forth.

     16.  LIENS.

     Tenant shall keep the Premises and the Building free from any liens arising
out of any work  performed,  materials  furnished  or  obligations  incurred  by
Tenant.  Landlord  shall have the right to post and keep posted on the  Premises
any notices that may be provided by law or which  Landlord may deem to be proper
for the  protection of Landlord,  the Premises and the Building from such liens.
In the event any such lien attaches to the Premises or the Property,  and Tenant
does not cause the same to be released by payment, bonding or otherwise,  within
ten (10) days after the  attachment  thereof,  Landlord shall have the right but
not the  obligation  to cause the same to be  released by such means as it shall
deem proper, and any sums expended by Landlord in connection  therewith shall be
payable by Tenant on demand with interest  thereon from the date of  expenditure
by Landlord at the rate  specified in Paragraph  3(e).  Landlord and Tenant each
hereby  warrant  to use best  efforts to notify  the other of the  existence  or
attachment of any and all liens contemplated under this Paragraph 15 within five
(5) business days of Landlord's or Tenant's actual knowledge of such lien(s).

     17.  ENTRY BY LANDLORD.

     Landlord,  upon  reasonable  notice to Tenant,  may enter the  Premises  at
reasonable  hours to (a) inspect the same;  (b) exhibit the same to  prospective
purchasers,  lenders or tenants;  (c) determine whether Tenant is complying with
all its obligations hereunder;  (d) supply janitor service and any other service
to  be  provided  by  Landlord  to  Tenant   hereunder;   (e)  post  notices  of
non-responsibility;  and (f) make  repairs or perform  maintenance  required  of
Landlord under the terms hereof,  make repairs to any adjoining space or utility
services,  or make repairs,  alterations or improvements to any other portion of

unlock all of the doors in, on or about the Premises  excluding Tenant's vaults,
safes and similar areas designated in writing by Tenant in advance; and Landlord
shall have the right to use any and all means which  Landlord may deem proper to
open  Tenant's  doors in an emergency in order to obtain entry to the  Premises,
and any  entry to the  Premises  obtained  by  Landlord  in a real or  perceived
emergency  shall not be considered or deemed to be a forcible or unlawful  entry
into or a detainer of the Premises or an eviction,  actual or  constructive,  of
Tenant from the Premises or any portion thereof.

     18.  SERVICES.

     (a)  Landlord  shall  maintain  the Common  Areas and  public  areas of the
Property,  including lobbies,  stairs,  elevators,  corridors and restrooms, all
exterior landscaping, the windows in the Building, the mechanical,  plumbing and
electrical  equipment  serving  the  Building,   and  the  structure  itself  in
reasonably good order and condition,  except for damage occasioned by the act or
omission of Tenant, its employees,  contractors, agents or invitees which damage
shall be repaired by Landlord at Tenant's expense.

     (b) Landlord shall cause to be furnished (1)  electricity  for lighting and
the  operation  of office  equipment,  on a 24-hour  basis,  with power usage in
excess of the time  allowance  referred  to in  Paragraph  18(d)  below to be at
Tenants cost, (2) heat and air  conditioning to the extent  reasonably  required
for the  comfortable  occupancy by Tenant in its use of the Premises  during the
period from 7:00 a.m. to 6:00 p.m. on  weekdays  excluding  holidays,  or as set
forth in the Rules and  Regulations,  which may be changed from time to time, or
such  shorter  periods  as  may be  prescribed  by any  applicable  policies  or
regulations adopted by any utility or governmental agency, (3) elevator service,
(4) lighting  replacement for building standard lights,  (5) restroom  supplies,
(6)  window  washing  with  reasonable  frequency,  (7) water for  lavatory  and
drinking  purposes,  and (8) security patrol services and janitor service during
the times and in the manner that such  services  are  customarily  furnished  in
comparable  office  buildings  in the  area;  provided  that in no  event  shall
Landlord be obligated to furnish janitor service on Saturdays, Sundays, or legal
holidays.  Landlord  may  establish  reasonable  measures  to  conserve  energy,
including but not limited to, automatic switching of lights after hours and more
efficient  forms  of  lighting,  so long as such  measures  do not  unreasonably
interfere  with Tenants use of the  Premises.  Landlord  shall not be in default
hereunder or be liable for any damages  directly or indirectly  resulting  from,
nor  shall  the  rental  herein   reserved  be  abated  by  reason  of  (i)  the
installation, use or interruption of use of any equipment in connection with the
furnishing of any of the foregoing services, (ii) failure to furnish or delay in
furnishing any such services when such failure or delay is caused by accident or
any  condition  beyond the  control of  Landlord  or by the making of  necessary
repairs  or  improvements  to the  Premises  or to the  Building,  or (iii)  the
limitation, curtailment, rationing or restrictions on use of water, electricity,
gas or any other form of energy  serving the  Premises or the  Building.  Tenant
hereby waives the provisions of California  Civil Code Section 1932 or any other
applicable  existing  or future  law or  ordinance  or  governmental  regulation
permitting  the  termination of this lease due to any  interruption,  failure or
inability to provide Landlord services as provided for herein.

     (c) Tenant shall reimburse Landlord, upon billing therefor, for the cost of
all heat or air conditioning  provided to the Premises during hours requested by
Tenant when such  services are not otherwise  furnished by Landlord  pursuant to
Paragraph  18(b)  above.  The cost of such after hours heat or air  conditioning
shall be a per-hour  charge  reflecting the electrical  energy,  labor and fixed
plant costs of running the heating and air  conditioning  system  which per hour
charge  shall be  fifteen  dollars  ($15.00).  In the event  that  Landlord  has
reasonable  cause  to  believe  that  the  cost  of  after  hours  heating,  air
conditioning  and  electricity  used by Tenant is exceeding the per hour charge,
Landlord  may at its option  install  separate  meter(s)  for the  Premises,  or
portions thereof, at Tenant's sole expense,  and Tenant thereafter shall pay all
charges of the utility providing service.

     (d) In the event that Landlord,  at Tenant's request,  provides services to
Tenant that are (i) in excess of those services  required to maintain  "Building
Standard  Improvements,"  or (ii) are not otherwise  provided for in this Lease,
Tenant shall pay  Landlord's  reasonable  charges for such services upon billing
therefor.

     19.  INDEMNIFICATION AND LIMITATION ON LANDLORD'S LIABILITY.

     (a) Tenant shall defend with competent counsel satisfactory to Landlord any
claims made or legal actions filed or threatened  against  Landlord with respect
to the  violation  of any Law, or the death,  bodily  injury,  personal  injury,
property damage, or interference with contractual or property rights suffered by
any third party occurring  within the Premises or resulting from Tenant's use or
occupancy of the Premises,  the Building, or the Common Areas, or resulting from
Tenant's activities in or about the Premises,  the Building, the Common Areas or
the Property, and Tenant shall indemnify and hold Landlord, Landlord's partners,
principals,  members,  employees, agents and contractors harmless from any loss,
liability,  penalties, or expense whatsoever (including any loss attributable to
vacant space which  otherwise would have been leased,  but for such  activities)
resulting  therefrom,  except to the  extent  proximately  caused by the  active
negligence or willful  misconduct of Landlord.  This indemnity  agreement  shall
survive until the latter to occur of (i) the date of the  expiration,  or sooner
termination,  of this  Lease,  or (ii)  the date  Tenant  actually  vacates  the
Premises.

     (b) Landlord shall not be liable to Tenant for, and Tenant hereby  releases
Landlord and its partners,  principals,  members,  officers,  agents, employees,
lenders,  attorneys,  and  consultants  from, any and all liability,  whether in
contract,  tort or on any other basis, for any injury to or any damage sustained
by Tenant,  Tenant's agents,  employees,  contractors or invitees, any damage to
Tenant's property, or any loss to Tenant's business, loss of Tenant's profits or
other  financial loss of Tenant  resulting from or attributable to the condition
of, the  management  of, the repair or  maintenance  of, the  protection of, the
supply  of  services  or  utilities  to,  the  damage in or  destruction  of the
Premises,  the  Building,  the Property or the Common Areas,  including  without
limitation  (i) the failure,  interruption,  rationing or other  curtailment  or
cessation in the supply of electricity,  water,  gas or other utility service to
the Property, the Building or the Premises; (ii) the vandalism or forcible entry
into the Building or the Premises;  (iii) the  penetration of water into or onto
any  portion  of the  Premises;  (iv) the  failure to  provide  security  and/or
adequate  lighting in or about the Property,  the Building or the Premises,  (v)
the existence of any design or  construction  defects  within the Property,  the
Building or the Premises; (vi) the failure of any mechanical systems to function
properly (such as the HVAC systems); (vii) the blockage of access to any portion
of the Property,  the Building or the  Premises,  except that Tenant does not so
release Landlord from such liability



                                       9.


<PAGE>


to  the  extent  such  damage  was  proximately   caused  by  Landlord's  active
negligence,  willful misconduct,  or Landlord's failure to perform an obligation
expressly  undertaken  pursuant to this Lease after a reasonable  period of time
shall have lapsed following  receipt of written notice from Tenant to so perform
such obligation.  In this regard,  Tenant acknowledges that it is fully apprised
of the  provisions  of Law  relating  to  releases,  and  particularly  to those
provisions contained in Section 1542 of the California Civil Code which reads as
follows:

     "A general  release does not extend to claims  which the creditor  does not
     know or suspect to exist in his favor at the time of executing the release,
     which if known by him must have materially affected his settlement with the
     debtor."

Notwithstanding such statutory provision,  and for the purpose of implementing a
full and complete release and discharge, Tenant hereby (i) waives the benefit of
such statutory  provision and (ii) acknowledges  that, subject to the exceptions
specifically  set forth  herein,  the  release and  discharge  set forth in this
paragraph is a full and  complete  settlement  and release and  discharge of all
claims and is intended to include in its effect, without limitation,  all claims
which Tenant, as of the date hereof, does not know of or suspect to exist in its
favor.

     20.  INSURANCE AND SUBROGATION.

     (a) Tenant shall maintain insurance complying with all of the following:

          (i) Tenant shall  procure,  pay for and keep in full force and effect,
     at all times during the Lease Term, the following:

               (1)  Comprehensive  general liability  insurance  insuring Tenant
          against liability for personal injury, bodily injury, death and damage
          to property occurring within the Premises,  or resulting from Tenant's
          use or occupancy of the Premises,  the  Building,  the Common Areas or
          the Property,  or resulting  from Tenant's  activities in or about the
          Premises or the Property, with coverage in an amount equal to Tenant's
          Required Liability Coverage (as set forth in Basic Lease Information),
          which  insurance  shall contain a "broad form  liability"  endorsement
          insuring  Tenant's  performance  of Tenant's  obligation  to indemnify
          Landlord as contained in this Lease;

               (2) Fire and property  damage  insurance  in so-called  "fire and
          extended  coverage"  form insuring  Tenant  against loss from physical
          damage to Tenant's personal  property,  inventory,  trade fixtures and
          improvements  within the  Premises  with  coverage for the full actual
          replacement cost thereof;

               (3) Plate glass insurance, at actual replacement cost;

               (4) Pressure vessel insurance, if applicable;

               (5) Product liability insurance  (including,  without limitation,
          if food and/or beverages are distributed,  sold and/or consumed within
          the Premises, to the extent obtainable, coverage for liability arising
          out of the  distribution,  sale,  use or  consumption  of food  and/or
          beverages  (including  alcoholic  beverages,  if  applicable)  at  the
          Premises for not less than Tenant's  Required  Liability  Coverage (as
          set forth in Basic Lease Information);

               (6) Workers compensation insurance and any other employee benefit
          insurance sufficient to comply with all laws; and

               (7) With respect to making of alterations or the  construction of
          improvements  or the like undertaken by Tenant,  contingent  liability
          and  builder's  risk  insurance,   in  an  amount  and  with  coverage
          reasonably satisfactory to Landlord.

          (ii) Each  policy of  liability  insurance  required  to be carried by
     Tenant  pursuant  to this  paragraph  or  actually  carried by Tenant  with
     respect to the Premises or the Property:  (i) shall, except with respect to
     insurance required by subparagraph  (a)(vi) above, name Landlord,  and such
     others as are designated by Landlord, as additional insureds; (ii) shall be
     primary  insurance  providing that the insurer shall be liable for the full
     amount of the loss,  up to and  including the total amount of liability set
     forth in the  declaration  of coverage,  without the right of  contribution
     from or prior payment by any other  insurance  coverage of Landlord;  (iii)
     shall be in a form  satisfactory  to  Landlord;  (iv) shall be carried with
     companies reasonably acceptable to Landlord with Best's ratings of at least
     A and XI;  (v) shall  provide  that such  policy  shall not be  subject  so
     cancellation,  lapse or change  except  after at least  thirty  days  prior
     written   notice  to   Landlord,   and  (vi)  shall   contain  a  so-called
     "severability"  or "cross liability"  endorsement.  Each policy of property
     insurance maintained by Tenant with respect to the Premises or the Property
     or any  property  therein (i) shall  provide  that such policy shall not be
     subject to cancellation,  lapse or change except after at least thirty days
     prior  written  notice to Landlord and (ii) shall contain a waiver and/or a
     permission  to waive by the  insurer  of any right of  subrogation  against
     Landlord, its partners,  principals,  members, officers,  employees, agents
     and  contractors,  which might  arise by reason of any  payment  under such
     policy or by reason  of any act or  omission  of  Landlord,  its  partners,
     principals, members, officers, employees, agents and contractors.

          (iii)  Prior to the time Tenant or any of its  contractors  enters the
     Premises,  Tenant shall deliver to Landlord, with respect to each policy of
     insurance  required to be carried by Tenant pursuant to this  Paragraph,  a
     copy of such policy  (appropriately  authenticated by the insurer as having
     been issued,  premium paid) or a certificate  of the insurer  certifying in
     fcrm satisfactory to Landlord that a policy has been issued,  premium paid,
     providing  the  coverage  required by this  Paragraph  aid  containing  the
     provisions specified herein. With respect to each renewal or replacement of
     any such  insurance,  the  requirements  of this Paragraph must be complied
     with not less than thirty days prior to the expiration or  cancellation  of
     the policies being renewed or replaced.  Landlord may, at any time and from
     time to time,  inspect and/or copy any and all insurance  policies required
     to be carried by Tenant  pursuant to this Article.  If  Landlord's  Lender,
     insurance broker, advisor or counsel reasonably determines at any time that
     the amount of coverage set forth herein for any policy of insurance  Tenant
     is  required to carry  pursuant to this  Paragraph  is not  adequate,  then
     Tenant shall  increase  the amount of coverage  for such  insurance to such
     greater amount as Landlord's Lender,  insurance broker,  advisor or counsel
     reasonably deems adequate.

     (b) With respect to insurance maintained by Landlord:

          (i) Landlord shall maintain, as the minimum coverage required of it by
     this Lease,  fire and property  damage  insurance  in  so-called  "fire and
     extended  coverage" form insuring Landlord (and such others as Landlord may
     designate)  against loss from physical damage to the Building with coverage
     of not less than one hundred percent (100%) of the full actual  replacement
     cost  thereof and  against  loss of rents for a period of not less than six
     months. Such fire and property damage insurance, at Landlord's election but
     without any requirements on Landlord's  behalf to do so, (i) may be written
     in so-called "all risk" form, excluding only those perils commonly excluded
     from such coverage by Landlord's  then property  damage  insurer;  (ii) may
     provide coverage for physical damage to the improvements so insured for up
     to the entire full actual  replacement cost thereof;  (iii) may be endorsed
     to cover  loss or damage  caused by any  additional  perils  against  which
     Landlord may elect to insure,  including  earthquake  and/or flood;  and/or
     (iv) may  provide  coverage  for loss of rents for a period of up to twelve
     months. Landlord shall not be required to cause such insurance to cover any
     of  Tenant's  personal  property,  inventory,  and trade  fixtures,  or any
     modifications,  alteration or improvements made or constructed by Tenant to
     or within the Premises.  Landlord shall use commercially reasonable efforts
     to obtain such insurance at competitive rates.

          (ii) Landlord shall maintain comprehensive general liability insurance
     insuring  Landlord (and such others as are designated by Landlord)  against
     liability for personal injury, bodily injury, death, and damage to property
     occurring  in, on or about,  or resulting  from the use or occupancy of the
     Property, or any portion thereof, with combined single limit coverage of at
     least Three Million Dollars


                                       10.


<PAGE>


     ($3,000.000).  Landlord  may carry such  greater  coverage  as  Landlord or
     Landlord's  Lender,  insurance broker,  advisor or counsel may from time to
     time  determine is  reasonably  necessary  for the adequate  protection  of
     Landlord and the Property.

          (iii) Landlord may maintain any other  insurance  which in the opinion
     of its insurance broker, advisor or legal counsel is prudent to carry under
     the given  circumstances,  provided such  insurance is commonly  carried by
     owners  of  property   similarly   situated  and  operating  under  similar
     circumstances.

     (c) Landlord hereby releases  Tenant,  and Tenant hereby releases  Landlord
and its respective partners,  principals,  members,  officers, agents, employees
and  servants,  from any and all  liability  for  loss,  damage or injury to the
property of the other in or about the Premises or the  Property  which is caused
by or results from a peril or event or  happening  which is covered by insurance
actually  carried  and in force at the time of the loss by the party  sustaining
such loss;  provided,  however,  that such waiver shall be effective only to the
extent  permitted  by the  insurance  covering  such loss and to the extent such
insurance is not prejudiced thereby.

     21.  DAMAGE OR DESTRUCTION.

     (a) If the  Premises,  the  Building or the Common Areas are damaged by any
peril after the Effective  Term  Commencement  Date,  Landlord shall restore the
same, as and when required by this paragraph, unless this Lease as terminated by
Landlord  pursuant to Paragraph 21(c) or by Tenant pursuant to Paragraph  21(d).
If this Lease is not so  terminated,  then upon the  issuance  of all  necessary
governmental  permits,  Landlord  shall  commence  and  diligently  prosecute to
completion the restoration of the Premises, the Building or the Common Areas, as
the case may be, to the extent then  allowed by law, to  substantially  the same
condition  in which it  existed  as of the Term  Commencement  Date.  Landlord's
obligation  to  restore  shall be  limited to the  improvements  constructed  by
Landlord.  Landlord shall have no obligation to restore any improvements made by
Tenant to the Premises or any of Tenant's personal property,  inventory or trade
fixtures. Upon completion of the restoration by Landlord, Tenant shall forthwith
replace or fully  repair all of Tenant's  personal  property,  inventory,  trade
fixtures  and  other  improvements  constructed  by  Tenant  to like or  similar
conditions  as  existed  at  the  time  immediately  prior  to  such  damage  or
destruction.

     (b) All  insurance  proceeds  available  from the fire and property  damage
insurance  carried  by  Landlord  shall be paid to and become  the  property  of
Landlord.  If this Lease is  terminated  pursuant to either  Paragraph  21(c) or
21(d), all insurance  proceeds  available from insurance carried by Tenant which
cover loss of property  that is Landlord's  property or would become  Landlord's
property on  termination  of this Lease shall be paid to and become the property
of Landlord,  and the remainder of such proceeds shall be paid to and become the
property of Tenant. If this Lease is not terminated pursuant to either Paragraph
21(c) or 21(d),  all insurance  proceeds  available  from  insurance  carried by
Tenant which cover loss to property that is Landlord's property shall be paid to
and become the  property  of  Landlord,  and all  proceeds  available  from such
insurance  which cover loss to property  which would only become the property of
Landlord  upon the  termination  of this  Lease  shall be paid to and remain the
property of Tenant.  The  determination  of  Landlord's  property  and  Tenant's
property shall be made pursuant to Paragraph 14(b).

     (c)  Landlord's  Right To  Terminate.  Landlord  shall  have the  option to
terminate this Lease in the event any of the following occurs,  which option may
be  exercised  only by  delivery  to Tenant of a written  notice of  election to
terminate within thirty days after the date of such damage or destruction:

          (i) The  Building  is  damaged  by any  peril  covered  by  valid  and
     collectible insurance actually carried by Landlord and in force at the time
     of such damage or destruction  (an "insured  peril") to such an extent that
     the  estimated  cost to restore the Building  exceeds the lesser of (i) the

     increased services by Landlord;

          (iii) in Landlord's  reasonable  judgment,  the financial worth of the
     proposed  assignee  is less than that of Tenant or does not meet the credit
     standards applied by Landlord;

     (e) For purposes of this  Article,  including any amendment to this Article
by way of addendum or other writing,  the term "assignment  consideration" shall
mean all  consideration  so be paid by the  assignee  to  Tenant or so any other
party on  Tenant's  behalf or for  Tenant's  benefit as  consideration  for such
assignment,  without  deduction for any commissions  paid by Tenant or any other
costs or expenses (including,  without limitation, tenant improvements,  capital
improvements,  building  upgrades,  permit  fees,  attorneys'  fees,  and  other
consultants'  fees) incurred by Tenant in connection with such  assignment,  and
the  term  "excess  rentals"  shall  mean  all  consideration  so be paid by the
sublessee  to Tenant or to any other  party on Tenant's  behalf or for  Tenant's
benefit for the  sublease of the  Premises in excess of the rent due to Landlord
under the terms of this Lease for the same  period,  without  deduction  for any
commissions  paid by Tenant or any other costs or expenses  (including,  without
limitation, tenant improvements, capital improvements, building upgrades, permit
fees,  attorneys'  fees,  and other  consultants'  fees)  incurred  by Tenant in
connection with such sublease.  Tenant agrees that the portion of any assignment
consideration and/or excess rentals arising from any assignment or subletting by
Tenant which is to be paid to Landlord pursuant to this Article now is and shall
then be the property of Landlord and not the property of Tenant.

     (f) All payments required by this Paragraph to be made to Landlord shall be
made in cash in full as and when they become due. At the time  Tenant,  Tenant's
assignee or sublessee  makes each such  payment to Landlord,  Tenant or Tenant's
assignee or sublessee, as the case may be, shall deliver to Landlord an itemized
statement  in  reasonable  detail  showing  the  method by which the  amount due
Landlord was  calculated  and certified by the party making such payment as true
and correct.

     (g)  The  rights   granted  so  Tenant  by  this  Article  are  granted  in
consideration of Tenant's express covenant that all pertinent  allocations which
are made by Tenant between the rental value of the Premises and the value of any
of  Tenant's  personal  property  which  may be  conveyed  or  leased  generally
concurrently  with and which may  reasonably  be  considered  a part of the same
transaction  as the permitted  assignment  or  subletting  shall be made fairly,
honestly and in good faith.  If Tenant shall breach this covenant,  Landlord may
immediately  declare  Tenant to be in default  under the terms of this Lease and
terminate  this Lease and/or  exercise  any other  rights and remedies  Landlord
would have  under the terms of this  Lease in the case of a material  default by
Tenant under this Lease.

     (h) No subletting or assignment,  even with the consent of Landlord,  shall
relieve Tenant of its personal and primary obligation so pay rent and to perform
all of the other  obligations  to be performed by Tenant  hereunder.  Consent by
Landlord to one or more assignments of Tenant's interest in this Lease or to one
or more  sublettings  of the Premises shall not be deemed so be a consent so any
subsequent  assignment or  subletting.  If Landlord shall have been ordered by a
court  of  competent  jurisdiction  to  consent  to a  requested  assignment  or
subletting,  or such an assignment  or  subletting  shall have been ordered by a
court of competent jurisdiction over the objection of Landlord,  such assignment
or  subletting  shall not be binding  between the  assignee (or  sublessee)  and
Landlord until such time as all conditions set forth in Paragraph 7.4 above have
been fully  satisfied  (to the extent not then  satisfied)  by the  assignee  or
sublessee,  including, without limitation, the payment to Landlord of all agreed
assignment considerations and/or excess rentals then due Landlord.

     25.  SUBORDINATION

     (a)  This  Lease  is  subject  to and  subordinate  so all  ground  leases,
mortgages and deeds of trust which affect the Building or the Property and which
are of public  record as of the Term  Commencement  Date,  and so all  renewals,
modifications,  consolidations, replacements and extensions thereof. However, if
the lessor under any such ground lease or any lender  holding any such  mortgage
or deed of trust shall advise Landlord that it desires or requires this Lease to
be made prior and superior  thereto,  then,  upon written request of Landlord to
Tenant,  Tenant  shall  promptly  execute,  acknowledge  and deliver any and all
customary or reasonable  documents or instruments which Landlord and such lessor
or lender deems necessary or desirable so make this Lease prior thereto.  Tenant
hereby consents to Landlord's ground leasing the land underlying the Building or
the  Property  and/or  encumbering  the Building or the Property as security for
future loans on such terms as Landlord shall desire,  all of which future ground
leases,  mortgages or deeds of trust shall be subject to and subordinate so this
Lease.  However,  if any lessor under any such future ground lease or any lender
holding such future  mortgage or deed of trust shall desire or require that this
Lease be made subject to and  subordinate to such future ground lease,  mortgage
or deed of trust, then Tenant agrees,  within ten days after Landlord's  written
request  therefor,  so execute,  acknowledge and deliver to Landlord any and all
documents  or  instruments  requested by Landlord or by such lessor or lender as
may be  necessary  or proper to assure the  subordination  of this Lease to such
future  ground  lease,  mortgage  or deed of trust,  but only if such  lessor or
lender  agrees so recognize  Tenant's  rights under this Lease and agrees not to
disturb  Tenant's quiet  possession of the Leased  Premises so long as Tenant is
not in default under this Lease. If Landlord assigns the Lease as security for a
loan, Tenant agrees to execute such documents as are reasonably requested by the
lender  and to  provide  reasonable  provisions  in the  Lease  protecting  such
lender's  security  interest  which are  customarily  required by  institutional
lenders making loans secured by a deed of trust.

     (b) Tenant shall, upon request, attorn (i) to any purchaser of the Building
or the Property at any  foreclosure  sale or private sale conducted  pursuant so
any security  instruments  encumberng the Building or she Property,  (ii) to any
grantee or  transferee  designated in any deed given in lieu of foreclose of any
security  interest  encumbering  the Building or the  Property,  or (iii) so the
lessor under an underlying  ground lease of the land  underlying the Building or
the  Property,  should  such  ground  lease be  terminated;  provided  that such
purchaser, grantee or lessor recognizes Tenant's rights under this Lease.

     26. ESTOPPEL  CERTIFICATE.  Tenant will, following any request by Landlord,
promptly execute and deliver to Landlord an esstoppel certificate (i) certifying
that this Lease is  unmodified  and in full force and effect,  or, if  modified,
stating the nature of such  modification  and certifying  that this Lease, as so
modified,  is in full force and effect,  (ii) stating the date to which the rent
and other charges are paid in advance,  if any, (iii)  acknowledging  that there
are not to  Tenant's  knowledge,  any  uncured  defaults on the part of Landlord
hereunder,  or specifying such defaults if any are claimed,  and (iv) certifying
such  other  information  about  this Lease as may be  reasonably  requested  by
Landlord,  its Lender or  prospective  lenders,  investors or  purchasers of the
Building or the Property.  Tenant's failure to execute and deliver such estoppel
certificate  within  ten  days  after  Landlord's  request  therefor  shall be a
material  default by Tenant under this Lease, and Landlord shall have all of the
rights and remedies  available to Landlord as Landlord  would  otherwise have in
the case of any  other  material  default  by  Tenant,  including  the  right to
terminate this Lease and sue for damages  proximately  caused thereby,  it being
agreed and  understood  by Tenant  that  Tenant's  failure  to so  deliver  such
estoppel certificate in a timely manner could result in Landlord being unable to
perform committed obligations to other third parties which were made by Landlord
in reliance  upon this  covenant of Tenant.  Landlord and Tenant intend that any
statement  delivered pursuant to this paragraph may be relied upon by any Lender
or purchaser or prospective  Lender or purchaser of the Building,  the Property,
or any interest in them.

     27. Tenant's Financial Information.  Tenant shall, within ten business days
after Landlord's  request therefor,  deliver to Landlord a copy of Tenant's (and
any guarantor's) current financial statements (including a balance sheet, income
statement and statement of cash flow, all prepared in accordance  with generally
accepted  accounting  principles,  and any  such  other  information  reasonably
requested by Landlord regarding Tenant's financial condition.  Landlord shall be
entitled to disclose  such  financial  statements  or other  information  to its
Lender, to any present or prospective  principal of or investor in Landlord,  or
to any  prospective  Lender or purchaser of the Building,  the Property,  or any
portion  thereof or interest  therein.  Any such  financial  statement  or other
intonation which is marked  "confidential" or "company secrets" (or is otherwise
similarly  marked by Tenant) shall be confidential and shall not be disclosed by
Landlord to any third party except as  specifically  provided in this paragraph,
unless  the same  becomes  a part of the  public  domain  without  the  fault of
Landlord.

     28.  RULES.

     Tenant shall  faithfully  observe and comply with the rules and regulations
annexed to this Lease,  and after notice thereof,  all reasonable  modifications
thereof  and  additions  thereto  from time to time  promulated  in  writing  by
Landlord. Landlord shall not be responsible to Tenant for the non-performance by
any  other  tenant  or  occupant  of  the  Building  of any of  said  rules  and
regulations.

secure  compliance with such provisions or to recover  damages  therefor,  or to
terminate this Lease or evict Tenant,  the party against whom judgement has been
rendered  shall  reimburse  the  prevailing  party  upon  demand for any and all
reasonable attorneys' fees and expenses so incurred by the prevailing party.

     30. WAIVER.

     The waiver by Landlord of any  agreement,  condition  or  provision  herein
contained  shall not be deemed  to be a waiver of any  subsequent  breach of the
same or any other agreement,  condition or provision herein contained, nor shall
any  custom  or  practice   which  may  grow  up  between  the  parties  in  the
administration  of the terms hereof be construed to waive or to lessen the right
of Landlord to insist upon the  performance by Tenant in strict  accordance with
such terms. The subsequent  acceptance of rental hereunder by Landlord shall not
be  deemed to be a waiver of any  preceding  breach by Tenant of any  agreement,
condition or  provision  of this Lease,  other than the failure of Tenant to pay
the  particular  rental so accepted,  regardless of Landlord's  knowledge of the
preceding breach at the time of acceptance or payment of the rental.

Landlord shall have no responsibility for damage to automobiles  incurred in the
Lot.

     (c) All parking  rights granted to Tenant in this Paragraph 31 shall be for
the sole use of the employees  and invitees of the named Tenant,  and no parking
rights may be assigned or sublet to any other party.

     (d)  Tenant  agrees  that it will  use its best  efforts  to  cooperate  in
programs  which may be undertaken by Landlord  independently,  or in cooperation
with local  municipalities or governmental  agencies or other property owners in

     any damage,  loss or expense  occasioned by the  interruption  of telephone
     service.

     (b) At such time as the entirety of the Leased  Premise is no longer leased

     telecommunications services in any way are interrupted, damaged or rendered
     less  effective,  except to the extent  caused by the grossly  negligent or
     willful  act or  omission  by  Landlord,  its agents or  employees.  Tenant

whatever  except as made in accordance  with the  provisions of this Lease,  the
Annual Fixed Rent as specified in Article 1 above in monthly installments at the
rate of  $15,423.25  during the Initial Term and the greater of  $15,423.25  per

financial  statements and a certificate of LESSEE's chief  financial  officer to
the effect that LESSEE's net worth has  increased as aforesaid.  In the event at
the time of such request LESSEE is not in default under this Lease, LESSOR shall
release to LESSEE $46,269.75.

quarterly financial statements on a continuing basis certified by LESSEE's chief
financial officer showing LESSEE's net worth. In the event LESSEE'S net worth at
any time falls  below  $5,500,000,  LESSEE  shall  thereupon  become  obligated,
without  notice from  LESSOR,  to forthwith  increase  the  security  deposit to
$92,539.50.

     5. USE OF  PREMISES.  LESSEE  shall use the  Leased  Premises  only for the

succeeding  month's payment of Annual Fixed Rent, for the amount of increases in

Leased  Premises  (as  hereinafter  defined)  exceed the product of (a) LESSEE's
Proportionate  Share of Operating Expenses Included in Annual Fixed Rent and (b)
the Total Rentable Floor Area of the Leased Premises.

     LESSOR's  Operating Expenses Allocable to the Leased Premises shall exclude
any expenses otherwise  separately billed to LESSEE, and shall be the sum of the
following:

     (a)  in the case of certain of the Operating  Expenses  attributable to the
          entire  Property  but  not to any  specific  lessees,  said  Operating
          Expenses  multiplied  by  LESSEE's  Proportionate  Share of  Operating
          Expenses as set forth in Article 1 above;

     (b)  in the case of  certain  Operating  Expenses  attributable  not to the
          entire Property but to certain specific lessees including LESSEE, said
          Operating Expenses  multiplied by the fraction the numberator of which
          is the Total  Rentable  Floor  Area of the  Leased  Premises,  and the
          denominator  of which is the total  rentable  floor area of all leased
          premises within the Property,  including the Leased Premises, to which
          such Operating Expenses are attributable;

     (c)  any Operating Expenses attributable specifically to LESSEE.

     Operating  Expenses,  if any,  attributable to LESSEE's use of the Property
during  other than  normal  business  hours (8:00 a.m.  until 6:00 p.m.,  Monday
through Friday,  and 8:00 a.m. until 12: noon Saturdays,  locally observed state
and federal holidays  excepted) may at LESSOR's option be billed  separately and
directly to LESSEE as Additional  Rent except the LESSOR agrees that there shall
be no  additional  costs  assessed to LESSEE for building or HVAC for the Leased
Premises and common areas outside of such regular  business hours long as LESSEE
operates its use at customary levels. The HVAC will be functional 7 days a week,
24 hours a day, but will be reduced by not more than 10 degrees,  plus or minus,
outside  normal  business  hours  which  are 8:00 am to 6:00 pm  Monday  through
Friday.

     LESSOR  shall  have the right  from time to time to  change  the  period of
accounting  for  Operating  Expenses to any period other than a Lease Year,  and
upon any such change,  all expense  items  referred to in this Article  shall be
appropriately  reapportioned.  In all  statements  rendered to LESSEE under this
Section  amounts  for  periods   partially  within  and  partially  without  the
accounting  periods shall be  appropriately  apportioned.  Any cost which is not
determinable  at the time of a statement may at LESSOR's  discretion be included
therein on the basis of LESSOR's  estimate,  and LESSOR  shall  render to LESSEE
after  determination  of such  cost  if  different  from  LESSOR's  estimate,  a
supplemental statement


                                       5

and appropriate adjustment shall be made according thereto.

     7. REAL ESTATE TAX. If, in any Tax Year (as herein  defined) or the portion
of a Tax Year which begins with LESSEE'S first  occupancy of the Leased Premises
and ends on June 30,  LESSOR's  Real  Estate Tax  Expenses  per  square  foot of
rentable  floor area of the Building  exceed  LESSEE's  share of Real Estate Tax
Expenses  Included in Annual Fixed Rent as specified in Article 1 herein,  then,
on or before the  thirtieth day  following  receipt by LESSEE of written  notice
from LESSOR that such increased  taxes are payable,  LESSEE shall pay to LESSOR,
as Additional Rent, the difference between (a) LESSOR's Real Estate Tax Expenses
Allocable to the Leased Premises,  as hereinafter defined,  less (b) the product
of (i) LESSEE's Share of Real Estate Tax Expenses  Included in Annual Fixed Rent
and (ii) the Total  Rentable  Floor Area of the Leased  Premises.  LESSOR  shall
promptly pay to LESSEE.  LESSEE's proportionate share of any refund or abatement
of Real Estate Tax Expenses received by LESSOR.

     LESSOR's Real Estate Tax Expense  Allocable to the Leased Premises shall be
determined by  multiplying  LESSOR'S Real Estate Tax  Expenses,  as  hereinafter
defined, for the Property times LESSEE's  Proportionate Share of Real Estate Tax
Expenses  as  set  forth  in  Article  1  herein.  "Tax  Year"  shall  mean  the
twelve-month   period  beginning  July  1  each  year,  or  if  the  appropriate
governmental  tax fiscal  period shall begin on any date other than July 1, such
other date.

     As used in this  Lease the term Real  Estate  Tax  Expenses  shall mean all
taxes  and  special  assessments  of  every  kind  and  nature  assessed  by any
governmental  authority  on the  Property  and which  the  LESSOR  shall  become
obligated to pay because of or in  connection  with the  ownership,  leasing and
operation  of the  Property,  and  reasonable  expenses of any  proceedings  for
abatement of taxes and assessments  including  appeals  thereof,  subject to the
following: (a) the amount of special taxes or special assessments to be included
shall be limited to the amount of the installment (plus any interest, other than
penalty  interest,  payable  thereon) of such special tax or special  assessment
(which shall be payable over the longest period permitted by law) required to be
paid  during the Tax Year in  respect of which such taxes are being  determined;
(b) there shall be  excluded  from such taxes all  income,  estate,  succession,
inheritance and transfer taxes;  provided,  however,  that if at any time during
the Lease Term the present system of ad valorem  taxation of real property shall
be  changed  so that in lieu of the whole or any part of the ad  valorem  tax on
real property,  there shall be assessed on LESSOR a capital levy or other tax on
the rents received with respect to the Property,  or a Federal,  State,  County,
Municipal, or other local income, franchise,  excise or similar tax, assessment,
levy or charge (distinct from any now in effect in the jurisdiction in which the
Property is located)  measured by or based,  in whole or in part,  upon any such
gross rents, then any and all of such taxes, assessments,  levies or charges, to
the extent so measured or based,  shall be deemed to be included within the term
"Real Estate Tax  Expenses".  A payment  shall be deemed to be in lieu of the ad
valorem tax on real  property  only if by reason  thereof and to the extent that
LESSOR is relieved of the payment of such tax or any increase thereof

     8. LATE  PAYMENT.  LESSEE  shall pay interest  (which  shall be  considered
additional  rent) at an annual rate which  shall be the lesser of eighteen  (18)

installment  of Annual Fixed Rent which is not received by LESSOR within 10 days
of due date.

     9.  UTILITIES.  LESSOR shall  provide  equipment as presently  existing and
installed  to heat  and cool the  Leased  Premises  in  season  at  temperatures

operated by LESSEE. Electricity will be furnished by LESSOR for building and

purposes  shall be supplied by LESSOR to the common area  lavatories  and Leased

hours which are 8:00 am to 6:00 pm Monday through Friday.

     10. COMPLIANCE WITH LAWS. LESSEE acknowledges that no trade, occupation, or
activity  shall be  conducted in the Leased  Premises or use made thereof  which

which will  adversely  affect,  increase  the premium of or make  voidable,  any

contents  thereof or which shall be contrary to any law or regulation  form time
to time established by the Insurance Services Office (or successor),  local Fire
Department,  or any similar body. LESSEE shall on demand reimburse  LESSOR,  and
all other tenants,  all extra  insurance  premiums caused by LESSEE's use of the
premises.

     12. MAINTENANCE OF PREMISES. LESSOR shall be responsible for all structural
maintenance  of the  Leased  Premises  and other  portions  of the  Property  as

     13.  ALTERATIONS.  Except as set forth in Exhibit A, LESSEE  shall not make
structural  alterations or additions of any kind to the Leased Premises, but may
make  nonstructural  alterations  provided LESSOR consents thereto in advance in
writing,  which  consent  shall  not  be  unreasonably  withheld  provided  said
alterations  are  consistent  in  appearance  and  quality  with the rest of the
Building  and  Property.  However,  LESSOR shall not be obligated to approve any
such alterations which would subject LESSOR to additional  expense to readapt or

expense,  shall  conform with  LESSOR's  construction  specifications,  shall be
performed in good and workmanlike  manner,  and shall comply with all applicable

within  ten  (10)  days  of  written  request  by  LESSOR.  Any  alterations  or
improvements  shall  become part of the real estate and the  property of LESSOR.
LESSEE shall remove any alteration or addition made by it and restore the Leased
Premises and other affected area(s),  if any, to the same condition as they were
in on the Lease  Commencement  Date upon the  expiration or  termination of this
Lease if LESSOR so directs,  unless prior written  approval for the  alterations
was granted by LESSOR.  Any  alterations  completed by LESSOR shall be `building
standard"  unless  noted  otherwise.  LESSOR shall have the right at any time to
change the arrangement  and layout of parking areas,  stairs,  walkways,  common
areas and other areas of the Property not contained  within the Leased Premises,
to install,  repair, replace,  remove, use, maintain and relocate for service to
the Leased Premises and to other parts of the Property,  pipes, ducts, conduits,
wires  and  appurtenant  fixtures  wherever  located  inside or  outside  of the

inconvenience  the  operation  of LESSEE's  business  on the Leased  Premises or
LESSEE's employees or invitees.

     14. ASSIGNMENT OR SUBLEASING.  LESSEE shall not assign,  mortgage,  pledge,
hypothecate  or otherwise  transfer  this Lease or sublet  (which term,  without
limitation,  shall include granting of concessions,  licenses,  and the like) or
allow any other firm or individual to occupy the whole or any part of the Leased
Premises without the prior written consent of LESSOR, which consent shall not be
unreasonably  withheld,  or suffer or permit this Lease or the leasehold  estate
hereby  created or any other  rights  arising  under this Lease to be  assigned,
transferred,   or  encumbered,   in  whole  or  in  part,  whether  voluntarily,
involuntarily,  or by  operation  of law  without the prior  written  consent of
LESSOR,  which consent shall not be unreasonably  withheld.  In the event of any
intent to assign this Lease or sublet any portion or all of the Leased Premises,
LESSEE  shall  notify  LESSOR in writing  of  LESSEE's  intent and the  proposed
effective  date of such  subletting  or  assignment,  and shall  request in such
notification  that LESSOR  consent  thereto,  provided that LESSOR may terminate
this LEASE in the case of a proposed  assignment,  or suspend this Lease for the
period  and  with  respect  to the  space  involved  in the  case of a  proposed
subletting,  by giving  written  notice of  termination or suspension to LESSEE,
with such  termination or suspension to be effective as of the effective date of
such assignment or subletting. LESSEE will


                                       8
<PAGE>


reimburse  LESSOR,  as additional  rent, for reasonable legal and other expenses
incurred  by LESSOR in  connection  with any  request by LESSEE  for  consent to
assignment or  subletting.  In the event that the fixed rental to be paid by any
sublessee,  assignee or  transferee of LESSEE shall exceed the Annual Fixed Rent
as set forth in Article 3 herein  payable  by LESSEE to LESSOR,  or in the event
that any sublessee, assignee or transferee shall pay to LESSEE a sum of money in
consideration for such sublease,  assignment or transfer,  then LESSEE shall pay
to LESSOR,  as additional  rent, a sum equal to fifty (50) percent of the amount
by which the fixed  rent  payable  by such  sublessee,  assignee  or  transferee
exceeds the Annual Fixed Rent payable  under Article 3 herein or an amount equal
to such sum of money.  No  assignment  or  subletting  and no  consent of LESSOR
thereto  shall  affect  the  continuing  primary  liability  of  LESSEE  (which,
following  assignment,  shall be joint and several  with the  assignee)  for the
payment of all rent and for the full performance of the covenants and conditions
of this Lease.  No consent to any of the foregoing in a specific  instance shall
operate  as a waiver in any  subsequent  instance,  and no  assignment  shall be
binding upon LESSOR or any of LESSOR's  mortgagees,  unless LESSEE shall deliver
to LESSOR an  instrument  in  recordable  form  which  contains  a  covenant  of
assumption  by the  assignee  running to LESSOR  and all  persons  claiming  by,
through or under  LESSOR,  but the failure or refusal of the assignee to execute
such instrument of assumption  shall not release or discharge  assignee from its
liability  as a lessee for the payment of all rent and for the full  performance
of the  covenants  and  conditions  of this Lease,  nor shall  execution of such
instrument of assumption  affect the continuing  primary liability of LESSEE for
the  payment  of all rent  and for the full  performance  of the  covenants  and
conditions  of this  Lease.  Notwithstanding  anything  contained  herein to the
contrary,  LESSEE may assign  this Lease or sublet the  premises  to any Parent,
affiliate or subsidiary  company of LESSEE  without the need to obtain  LESSOR'S
consent so long as LESSEE remains  primarily  liable on the Lease and so long as
LESSEE provides LESSOR fifteen (15) days written notice prior to such assignment
or subletting.  Affiliate  shall include any entity which directly or indirectly
controls LESSEE or is a successor to LESSEE by name,  merger,  consolidation  or
other  operation  of law or any entity to whom all or  substantially  all of the
assets of LESSEE are conveyed.

     15.  SUBORDINATION.  LESSEE agrees at the request of LESSOR to  subordinate
this Lease to any first mortgage or other security  interest  hereafter  created
covering  the Leased  Premises or any portion of the Leased  Premises and to any
renewal, modification,  replacement or extension or any existing first mortgage,
or any  mortgage or  security  interest  hereinafter  created and to any and all
advances made or to be made thereunder or to any ground Lease of the Property or
the Building, provided that the mortgagee or holder of such security interest or
ground Lessor agrees,  for itself and its successors and assigns in writing with
the LESSEE that so long as LESSEE shall not be in default under this Lease,  the
mortgagee or other  holder of such  security  interest or ground  LESSOR and its
successors  and assigns  will not disturb the  peaceful  quiet  enjoyment of the
Leased  Premises  by the  LESSEE.  LESSEE  also  agrees that if this Lease is so
subordinated, no entry under any mortgage or sale for the purpose of foreclosing
the same or entry for  termination  of any ground  Lease shall be regarded as an
eviction  of LESSEE,  constructive  or  otherwise,  or give  LESSEE any right to
terminate  this Lease,  whether it attorns or becomes LESSEE of the mortgagee or
new owner,  and such  mortgage,  or security  interest to which this Lease shall
become  subordinated may contain such other terms,  provisions and conditions as
are usual and  customary.  LESSEE  agrees that it will,  within ten (10) days of
receipt of written  request  of the  LESSOR,  execute  and  deliver  any and all
instruments  necessary  or  desirable  to  give  effect  to or  notice  of  such
subordination in such forms as may be required by such mortgagee or other holder
of such  security  interest  or  ground  Lessor,  and  LESSOR  shall  deliver  a
Non-Disturbance  Agreement  executed by such  mortgagee  or other holder of such
security interest or ground lessor to LESSEE within 30 days thereafter.


                                       9
<PAGE>


     16.  ESTOPPEL  CERTIFICATES.  Upon ten (10) days prior  written  request by
LESSOR or LESSEE,  the other  party  agrees to execute  and  deliver an estoppel
certificate  certifying  that this  Lease is  unmodified  and in full  force and
effect  (or,  if there  have been any  modifications  that this Lease is in full
force and effect as modified  and stating  the  modifications)  and the dates to
which the Annual Fixed Rent,  additional  rent and other  charges have been paid
through  and any other  information  reasonably  requested.  Any such  statement
delivered  pursuant  to this  Article  may be  relied  upon  by any  prospective
purchaser, mortgagee or lending source.

     17. LESSOR'S ACCESS.  LESSOR or agents of LESSOR may upon at least 24 hours
advance  notice at reasonable  times enter to view the Leased  Premises and may,
after  providing  notice  to  LESSEE,  remove at  LESSEE's  expense  any  signs,
alterations  or additions  not approved and  constructed  or installed as herein
provided,  may make such repairs and alterations as LESSOR may deem necessary to
avert an emergency, may make any repairs which LESSEE is required but has failed
to do, and may show the leased premises to others. LESSOR agrees to use its good
faith efforts to avoid  interfering  with LESSEE's use of the Leased Premises in
carrying out the activities permitted by this Paragraph 17.

     18. SNOW REMOVAL. The plowing of snow from all common roadways:  accessways
and unobstructed parking and loading areas, and the clearing of snow from common
walkways  sufficient to provide  access to the  Building,  shall be performed by
LESSOR or its agents.

     19. ACCESS AND PARKING.  LESSEE shall have the non-exclusive right, without
additional  charge,  to use the number of parking spaces specified in Article 1,
said  spaces to be  located  within the  parking  area  provided  for the Leased
Premises  in common  with others  entitled  to the use  thereof.  LESSEE may not
sublease any parking space so allocated.  Neither LESSOR or LESSEE will obstruct
in any manner any portion of the Building or the Property, including the parking
area, walkways or approaches to said Building or Property, so as to unreasonably
interfere with either  party's access to the Building or to the Leased  Premises
and LESSEE will conform to all reasonable  rules now or hereafter made by LESSOR
for  parking,  and for  the  care,  use,  or  alteration  of the  Property,  its
facilities  and  approaches.  LESSOR  shall have the right to impose  reasonable
controls on the operation of the parking area,  including but not limited to the
installation of access gates. The issuance of identifying  cards and/or stickers
to those employees,  guests and invitees of LESSEE who will be using the parking
area, and the designation of certain  portion(s) of the parking area as reserved
for such purpose(s) as LESSOR in its sole judgement may determine, provided that
such  designation  shall not reduce the number of spaces allocated to LESSEE and
shall not materially interfere with LESSEE's use of the Leased Premises.

     LESSEE further  warrants that LESSEE will not permit any employee,  visitor
or invitee to violate this or any other  covenant or  obligation  of LESSEE.  No
vehicle  shall be stored  or left in any  parking  area for more than  seven (7)
consecutive  nights without LESSOR's written  approval.  From December 1 through
March 30 annually,  however,  all unattended  parking will be prohibited between
12:00 AM and 5:00 AM except in those areas which may at LESSOR's  discretion  be
specifically  designated for assigned  overnight  parking as shown on Exhibit B,
with a minimum of ten (10) spaces. Unregistered or disabled vehicles, or storage
trailers of any type, may not be parked overnight at any time.  LESSEE agrees to
assume all expense and risk for towing of any  misparked  vehicle  belonging  to
LESSEE or LESSEE's agents, employees, business invites, or callers, at any time.
LESSEE shall have access to the termination points for telephone wiring and data
wiring on a 24 hours  basis.  LESSEE shall have the right to use, in common with
LESSOR and any other


                                       10
<PAGE>


tenants, facilities for deliveries and handicapped access during normal business
hours which are 8:00 am to 6:00 pm Monday through Friday.

     20. LESSEE'S LIABILITY  INSURANCE.  LESSEE will secure and carry at its own
expense a  comprehensive  general  liability  policy  insuring LESSEE and LESSOR
against any claims based on bodily injury  (including  death) or property damage
arising out of the condition of the Leased Premises or their use by LESSEE, such
policy to insure LESSEE and LESSOR  against any claim up to One Million  Dollars
($1,000,000)  per  occurrence  for injury or death to one person,  Three Million
Dollars  ($3,000,000)  for  injury or death to more than one  person in the same
accident,  and One Million  Dollars  ($1,000,000)  for damage to property.  Such
limits shall be subject to increase from time to time during the Lease Term. The
amount of such insurance  shall not limit LESSEE's  liability nor relieve LESSEE
of any obligation hereunder.

     Upon the  commencement  of the Lease Term  LESSEE will  promptly  file with
LESSOR  certificates   reasonably  satisfactory  to  LESSOR  showing  that  such
insurance is in force, accompanied by evidence of the payment of the premium for
the policy,  and thereafter will file renewal  certificates at least thirty (30)
days  prior  to  the  expiration  of  any  such  policies.  All  such  insurance
certificates  shall  provide  that  such  policies  shall not be  cancelled  nor
materially  changed  without at least ten (10) days prior written notice to each
assured  named  therein.  LESSEE  may,  at  LESSEE's  cost  maintain  such other
liability insurance as LESSEE may deem necessary to protect it.

     LESSEE shall assume exclusive control of the Leased Premises,  and all tort
liabilities incident to the control or ownership thereof and agrees to indemnify
and hold the LESSOR free and  harmless  from any and all  liability,  penalties,
losses,  damages, costs and expenses,  causes of action, claims or judgements or
encumbrances  created or suffered by the LESSEE, and from any and all liability,
penalties,  losses,  damages,  costs and expenses,  causes of action, claims, or
judgements  arising  from  injury to  persons or  property  of any nature on the
Leased  Premises or the  Property,  occasioned  by any acts or  omissions of the
LESSEE or of its  employees,  agents,  invitees,  visitors,  callers,  servants,
subtenants, or independent contractors, and arising out of the use or occupation
of said  Leased  Premises  by LESSEE  from any  neglect  or misuse on the Leased
Premises or by any reason of nuisance made or suffered on the Leased Premises by
LESSEE excluding in all cases, loss or damage due to LESSOR's acts or  omissions
and also against all legal costs and charges, including counsel fees, reasonably
incurred in and about such matters and the defense of any action  arising out of
the same, or in discharging the Leased Premises or any part thereof from any and
all liens that may be placed thereon from charges incurred by LESSEE,  except as
caused by LESSORS negligence.  If LESSOR intervenes in or becomes a party to any
such action or actions growing out of this Lease to protect its rights, then the
LESSEE shall pay LESSOR's reasonable  attorneys' fees in such action or actions.
LESSOR  agrees  to  carry,  at its own  expense,  liability  insurance  covering
injuries or damage to persons or property arising out of LESSOR's  negligence on
or about the Building or Property.

     21. WAIVER OF SUBROGATION.  Any casualty and liability insurance carried by
LESSEE  or  LESSOR  with  respect  to the  Leased  Premises,  the  Property,  or
occurrences thereon shall include a clause or endorsement denying to the insurer
rights of  subrogation  against the other  party to the extent  rights have been
waived by the insured  prior to the  occurrence  of injury or loss.  Each party,
notwithstanding any provisions of this Lease to the contrary,  hereby waives any
rights of recovery  against the other for injury or loss due to hazards  covered
by such insurance containing such  antisubrogation  clause or endorsement to the
extent of the indemnification received


                                       11
<PAGE>


thereunder.

     22. FIRE,  CASUALTY,  EMINENT DOMAIN.  Should a substantial  portion of the
Leased  Premises  be  substantially  damaged  by fire or other  casualty,  or if
substantial  damage as a result of fire or casualty to the  Building or Property
or taking by eminent domain, shall deprive LESSEE of access or use of the Leased
Premises,  this Lease shall  terminate  at LESSEE's  election by written  notice
given to LESSOR within sixty (60) days after occurrence of the event giving rise
to the election to terminate  which notice shall specify the  effective  date of
termination.  Should a  substantial  portion of the Leased  Premises,  or of the
Property,  be substantially  damaged by fire or other casualty,  or by action of
public or other authority in consequence  thereof or be taken by eminent domain,
or should LESSOR receive  compensable damage by reason of anything lawfully done
in  pursuance  of public or other  authority,  this  Lease  shall  terminate  at
LESSOR's election,  which may be made  notwithstanding  LESSOR's entire interest
may have been divested, by written notice given to LESSEE within sixty (60) days
after the  occurrence  of the event  giving rise to the  election to  terminate,
which notice shall specify the effective date of termination.

     The  effective  date of any  termination  by LESSOR or  LESSEE  under  this
Article shall be not less than fifteen (15) nor more than thirty (30) days after
the date of such notice of termination.  For the purpose of this Article, damage
or taking  shall be  considered  substantial  if the time  needed  for LESSOR to
perform repairs and/or construction necessary to put the Leased Premises or such
remainder in proper  condition for use and  occupation is estimated by LESSOR to
exceed two (2) months,  or if more than thirty (30) percent of the  non-wetlands
land area of the Property,  or if more than ten (10) percent of the Building, or
if more than ten (10) percent of the Leased  Premises  are so taken.  In case of
any such damage or taking,  LESSOR shall notify  LESSEE  within thirty (30) days
after the occurrence  thereof of LESSOR's estimate of the time needed to perform
the repairs  and/or  construction  necessary to put the Leased  Premises or such
remainder in proper condition for use and occupancy, or of the percentage of the
non-wetlands land area, or of the Building, or of the Leased Premises taken.

     If in any such case the  Leased  Premises  are  rendered  unfit for use and
occupation and the Lease is not so terminated, LESSOR shall use due diligence to
put the Leased Premises, or in case of taking what may remain thereof (excluding
any items  installed  or paid for by Tenant,  which  Tenant may be  required  to
remove),  into proper  condition for use and occupation and a just proportion of
the Annual Fixed Rent and any additional rent according to the nature and extent
of the injury shall be abated until the Leased  Premises or such remainder shall
have  been  put by  LESSOR  in such  condition  and in case  of a  taking  which
permanently  reduces the area of the Leased  Premises,  a just proportion of the
Annual Fixed Rent and  additional  rent shall be abated for the remainder of the
Lease Term.

     LESSOR  reserves  to itself any and all rights to receive  awards  made for
damages  to the  Leased  Premises  and the  Property  and the  leasehold  hereby
created,  or any one or more of them,  accruing by reason of exercise of eminent
domain or by reason of anything  lawfully  done in  pursuance of public or other
authority.  LESSEE hereby  releases and assigns to LESSOR all of LESSEE's rights
to such awards, and covenants to deliver such further assignments and assurances
thereof  as LESSOR may from time to time  request  It is agreed and  understood,
however,  that  LESSOR  does not reserve to itself and LESSEE does not assign to
LESSOR,  any damages payable for (i) movable trade fixtures  installed by LESSEE
or anybody  claiming  under  LESSEE at its own  expense or fixtures or items the
removal of which is required or permitted by any  agreement  given  pursuant the
Lease, or (ii) relocation expenses recoverable by LESSEE from



                                       12
<PAGE>


such authority in a separate action.

     23.   INTERRUPTIONS.   LESSOR  shall  not  be  liable  to  LESSEE  for  any
compensation or reduction of rent by reason of inconvenience or annoyance or for
loss of business  arising  from power and other  utility  losses,  shortages  or
malfunctions,  the necessity of LESSOR's entering the Leased Premises for any of
the purposes in this Lease  authorized,  or for repairing the Leased Premises or
any other portion of the Property  however the necessity may occur unless due to
LESSOR's gross negligence or malfeasancy. In case LESSOR is prevented or delayed
from making any repairs, alterations or improvements, or furnishing any services
or performing  any other  covenant or duty to be performed on LESSOR's  part, by
reason of any and all causes reasonably  beyond LESSOR'S  control,  LESSOR shall
not be  liable to  LESSEE  therefor,  nor shall the same give rise to a claim in
LESSEE's favor that such failure  constitutes  actual or constructive,  total or
partial,  eviction from the Leased  Premises.  LESSOR reserves the right to stop
any  service  or  utility  system,  when  necessary  by  reason of  accident  or
emergency,  or until necessary repairs have been completed,  provided,  however,
that in each instance of stoppage, LESSOR shall exercise reasonable diligence to
eliminate the cause thereof

     24.  BROKERAGE.  LESSEE  warrants and  represents to LESSOR that LESSEE has
dealt with no broker other than R.W.  Holmes  Realty Co., Inc.  ("BROKER")  with
respect  to this  Lease  and  LESSEE  agrees to  indemnify  LESSOR  against  any
brokerage  claims  arising by virtue of this Lease,  other than from the BROKER.
LESSOR  warrants and  represents to LESSEE that LESSOR has employed no exclusive
broker or agent in connection with the letting of the Leased Premises other than
the BROKER,  and agrees to indemnify LESSEE against any brokerage claims arising
by virtue of this Lease,  other than from the BROKER.  Pursuant to its exclusive
agency  agreement  with the BROKER,  LESSOR  shall only be  responsible  for the
brokerage commission due the BROKER.

     25. SIGNS.  LESSEE may display signs on the Leased  Premises  including one
(1) free  standing  sign by road  entrance and one free  standing  sign near the
building entrance.  LESSEE shall,  however,  first obtain the written consent of
LESSOR,  which  consent  shall not be  unreasonably  withheld and any  approvals
required under  applicable  by-laws or regulations,  before erecting any sign on
the Property, and shall obtain written approval as to size, content, appearance,
and location of all authorized signs.

     26.  DEFAULT.  BANKRUPTCY AND  ACCELERATION  OF RENT. In the event that (a)
LESSEE  files a petition  for  adjudication  as a bankrupt  or shall be declared
bankrupt or insolvent according to law, or if an involuntary  petition under any
of the  provisions  of the  Bankruptcy  Act is filed  against  LESSEE and is not
dismissed within sixty (60) days thereafter,  or if any assignment shall be made
of LESSEE's  property for the benefit of creditors;  or (b) LESSEE shall default
in the observance or performance of any of LESSEE's  covenants,  agreements,  or
obligations  hereunder,  other than  substantial  monetary  payments as provided
below,  and such  default  shall not be  corrected  with  thirty (30) days after
written notice thereof, then LESSOR shall have the right thereafter,  while such
default  continues,  and without  demand or further  notice to re-enter and take
complete  possession of the Leased  Premises,  or declare the term of this Lease
ended,  and to remove  LESSEE's  effects,  without being guilty of any manner of
trespass,  and without  prejudice to any remedies  which might be otherwise used
for arrears of rent or other  default or breach of covenant.  In addition to the
foregoing,  if LESSEE shall default in the payment of Annual Fixed Rent,  taxes,
or additional rent, and such default shall continue for ten (10)


                                       13
<PAGE>


days  after  written  notice  thereof  and,  because  both  parties  agree  that
nonpayment of said sums when due is a considerable and significant breach of the
Lease, and, because the payment of rent in monthly  installments is for the sole
benefit and  convenience of LESSEE,  then, if Landlord  elects to terminate this
Lease,  the net present  value of the entire  balance of rent over and above the
net present value of the Fair Market Rental Value of the Leased Premises for the
balance of the term shall, at the option of LESSOR,  become  immediately due and
payable, and, in addition,  LESSOR shall have all other rights of LESSOR, as set
forth in this Article, for a default by LESSEE.

     LESSOR,  without being under any  obligation  to do so and without  thereby
waiving  any  default,  may remedy  same for the  account  and at the expense of
LESSEE.  If LESSOR  pays or incurs any  obligations  for the payment of money in
connection therewith, including but not limited to reasonable attorney's fees in
instituting,  prosecuting or defending any action or proceeding,  such sums paid
or  obligations  incurred  and  costs,  shall be paid to  LESSOR  by  LESSEE  as
additional  rent.  Any sums  received by LESSOR shall be applied first to offset
any outstanding invoice or other payment due to Lessor, with the balance applied
to  outstanding  rent.  Notwithstanding  the  foregoing,  LESSEE  agrees  to pay
reasonable   attorney's  fees  incurred  by  LESSOR  in  enforcing  any  or  all
obligations  of LESSEE under this Lease at any time.  LESSOR  agrees to use good
faith efforts to relet the Premises in the event of a  termination  of the Lease
pursuant to this Paragraph 26.

     Any and all rights and remedies which LESSOR may have under this Lease,  at
law and equity,  shall be cumulative and shall not be deemed  inconsistent  with
each other, and any two or more of all such rights and remedies may be exercised
at the same time insofar as permitted by law.

     27. NO ACCORD AND  SATISFACTION.  No  acceptance  by LESSOR of a lesser sum
than the Annual  Fixed Rent and  additional  rent then due shall be deemed to be
other than on account of the  earliest  installment  of such rent due, nor shall
any endorsement or statement on any check or any letter  accompanying  any check
or payment as rent be deemed an accord and  satisfaction,  and LESSOR may accept
such check or payment without prejudice to LESSOR's right to recover the balance
of such installment or pursue any other remedy provided in this Lease.

     28.  NOTICES.  Any  notice  from  LESSOR to LESSEE  relating  to the Leased
Premises or to the occupancy  thereof shall be deemed duly served,  if delivered
to  LESSEE  by  certified  mail,  return  receipt  requested,  postage  prepaid,
addressed to LESSEE at the Leased Premises.

or at such  other  address  as LESSOR or LESSEE may from time to time in writing
designate.

     29.  OCCUPANCY.  In the event that LESSEE takes possession of said premises
prior to the Lease  Commencement  Date,  LESSEE will  perform and observe all of
LESSEE's  covenants from the date upon which LESSEE takes possession  except the
obligation  for the payment of extra rent for any period of less than one month.
LESSEE  shall not remove  LESSEE's  goods or property  from the Leased  Premises
other than in the ordinary and usual  course of business,  without  having first
paid and  satisfied  LESSOR  for all rent which may become due during the entire
term of this Lease. In the event that LESSEE  continues to occupy or control all
or any part of the Leased  Premises  after the agreed  termination  date of this
Lease  without the written  permission  of LESSOR,  then all other terms of this
Lease  shall  continue to apply  except  that rent shall be due in full  monthly
installments  at a rate of one hundred  fifty (150)  percent of that which would
otherwise be due under this Lease, it being understood  between the parties that
such extended  occupancy as a tenant at sufferance is solely for the benefit and
convenience  of LESSEE and such has greater  rental value and, in the event that
LESSEE  continues to occupy or control the Leased  Premises for a period of more
than one month  after  the Lease  termination  date,  LESSEE  shall be liable to
LESSOR for any and all loss,  damages or expenses  incurred by LESSOR.  LESSEE's
control or occupancy of all or any part of the Leased  Premises  beyond midnight
on the last day of any monthly rental period shall constitute LESSEE's occupancy
for an entire  additional  month, and increased rent as provided in this Article
shall be due and payable immediately in advance.

     30.  FIRE  PREVENTION.  LESSEE  agrees to use every  reasonable  precaution
against  fire and LESSOR  agrees  that the Leased  Premises  (upon  delivery  to
LESSEE)  and  the  Building   shall  comply  with  the  local  Fire   Marshall's
requirements for approved,  labeled fire  extinguishers  and emergency  lighting
equipment

     31.  OUTSIDE AREA.  Except for permitted  parking,  no goods,  equipment or
things of any type or  description  shall be held or stored  outside  the Leased
Premises at any time without  express written  approval from LESSOR.  Any goods,
equipment  or things left outside the Leased  Premises  without  LESSOR'S  prior
written  consent  shall be deemed  abandoned  and may be removed  after 24 hours
notice by  LESSOR.  LESSEE  agrees to pay upon  written  notice  all  reasonable
charges, as additional rent associated with said removal.

4.0     ASIC PRODUCT DES1GN

4.1     IBM's ASIC development checklists shall document the development of each
        of  Buyer's  Product  design(s).  

        4.1.1 The IDR will be used to make a preliminary  feasibility assessment
        of each of Buyer's proposed Product design(s) and to advise Buyer of any
        areas where Buyer's design(s) do not conform to IBM design requirements.

        4.1.2 The RTL shall include, expressly or by specific incorporation, the
        design specifications for each Product required by Buyer to successfully
        place,  route,  time and  conform  to LSSD  and  provide  static  timing
        analysis.  The RTL shall also document the fact that such information is
        available  to Buyer  and has been  communicated  to  Buyer  before  each
        Product  netlist is released  to layout.  Buyer's  signature  on the RTL
        shall record Buyer's  acknowledgment  of satisfactory  completion of all
        work on such Product through such Milestone.

        4.1.3 Buyer's  signature on the RTM shall record Buyer's  acknowledgment
        of (i)  satisfactory  completion of all work on such Product through the
        RTM  Milestone  and (ii) the  specifications  to  which  IBM's  warranty
        obligations,  set forth in  Section  14.0,  apply.  To the  extent  that
        specifications  and test parameters  contained in the RTM vary those set
        forth in the RTL, the specifications contained in the RTM shall govern.

        4.1.4  Buyer's  signature  on the RTL and RTM  checklists  shall  not be
        unreasonably withheld.

4.2     IBM shall use commercially  reasonable efforts to meet all Milestone and
        Prototype delivery schedules.

24.3    Any data  relating  to a Product  design that Buyer is to furnish to IBM
        must be compatible with IBM tools, with which IBM will verify all design
        and engineering work for conformance to IBM's technology ground rules.

4.4     Buyer may request changes to any Product design during the course of the
        SOW by  submitting a written  request to IBM. Upon receipt by IBM of any
        such request,  IBM shall promptly  inform Buyer in writing of the effect
        of the requested change on the SOW including estimated completion of the
        design work to incorporate  any requested  changes and applicable  price
        increase(s), if any. IBM shall immediately halt work until the Buyer and
        IBM agree,  in writing,  to changes in pricing,  completion date and any
        other terms of the SOW,  which are  affected by such request for change.
        If Buyer fails to order a restart of work within fifteen  calendar days,
        then the cancellation charges in Section 9.0 of Attachment C will apply.

4.5     Buyer may,  for the  applicable  unit price  specified in Section 6.0 of
        Attachment C, order  Prototypes in addition to the quantity  included in
        the NRE Charges at any time  before  five (5) working  days prior to RTM
        signoff.  Subject to the RTM signoff and adequate yield from the initial
        wafer lot, IBM shall use reasonable  efforts to deliver such  additional
        Prototypes  within five (5) working days of the estimated  delivery date
        for Prototypes.

4.6     Subject to the terms and conditions of this Agreement, both parties will
        exercise  reasonable  diligence in performing the design  activities set
        forth in the SOW for each Product.

4.7     IBM  agrees  to  provide  Products  to Buyer as  requested  by Buyer and
        accepted by IBM subject to the provisions of this Agreement.

4.8     All computer  data  provided to IBM by Buyer  supplied  pursuant to this
        Agreement  will be, to the best of supplier's  knowledge,  free from any
        virus, worm or other routines that would permit  unauthorized  access or
        otherwise harm software, hardware or data.

5.0     PRODUCT DEMAND FORECASTS

5.1     The Product demand forecasts agreed to by Buyer and IBM are set forth in
        Attachment C. The forecasts cover yearly periods through 1999 broken out
        by Product  and month.  During  the term of this  Agreement,  Buyer will
        provide IBM with updated  Product  demand  forecasts on a monthly  basis
        covering a rolling  twelve (12) month  period (not to extend  beyond the
        Contract Period),  which will be reviewed for approval by IBM within ten
        (10) days of receipt by IBM. Updated forecasts shall be in substantially
        the same format as the first forecast in Attachment C.  Forecasts  shall
        be provided  to IBM's  Customer  Account  Representative  as  identified
        above.  Forecasts  shall  constitute  good  faith  estimates  of Buyer's
        anticipated requirements for Products for the periods indicated based on
        current market  conditions,  and IBM's acceptance shall constitute IBM's
        good faith intention to quote and supply such  requirements if requested
        and   ordered   by  Buyer  in   accordance   with  this   Section   5.0.
        Notwithstanding the foregoing,  Product demand forecasts accepted by IBM
        shall  not  contractually  obligate  IBM to  supply,  nor  contractually
        obligate Buyer to purchase, the quantities of units of Product set forth
        in such forecasts.

5.2     Buyer  may  request   Products  that  exceed  Product  demand  forecasts
        previously  accepted by IBM.  Such  requests are subject to rejection by
        IBM  for   any   reason,   including,   without   limitation,   resource
        availability. In the event IBM rejects such a request, IBM shall provide
        buyer  with  written  notice  of such  rejection  within  fourteen  (14)
        calendar  days  of  Buyer's  Request,  specifying  the  reason  for  the
        rejection.

        Section 2.0 of  Attachment  C. IBM shall  invoice Buyer for all units of
        Product upon shipment.  All payments  under this Agreement  shall be due
        within  thirty  (30) days of the date of  invoice.  If  Buyer's  account
        becomes in arrears or if Buyer  exceeds  its credit  limit with IBM,  in
        addition to any other right under this Agreement, IBM reserves the right
        to cease  development work or stop shipment to Buyer or ship to Buyer on
        a  cash-in-advance  basis,  or other  mutually  agreeable  terms,  until
        Buyer's account is again current.

9.2     Buyer is  responsible  for all  state  and  federal  sales and use taxes
        related to Products, except for IBM's own corporate income taxes.

9.3     Buyer  shall  provide  IBM with a copy of a valid  reseller's  exemption
        certificate for Products purchased for resale for each applicable taxing
        jurisdiction.  Based on such certificate, and where the law permits, IBM
        will treat Buyer as exempt from applicable state and local sales tax for
        Products purchased hereunder. Buyer shall notify IBM promptly in writing
        of any  modification  or  revocation of its exempt  status.  Buyer shall
        reimburse IBM for any and all assessments  resulting from a refusal by a

        interest in accordance with the laws of the State of New York.

11.0    CANCELLATION CHARGES, RESCHEDULING, ORDER CHANGE PROVISIONS [**]

11.1    Buyer may cancel a purchase  order or any portion  thereof  upon written
        notice to IBM.  If Buyer  cancels a purchase  order for NRE  Services or
        Prototypes,  or if Buyer  unreasonably  withholds its signature from the
        RTL or RTM, IBM will cease further work in  connection  with the Product
        and invoice Buyer for (i) the total of all unpaid NRE Charges applicable
        to the next development Milestone (Section 2.0 of Attachment C) and (ii)
        an NRE  cancellation  charge pursuant to Section 3.0 of Attachment C and
        the applicable unit price for any canceled  Prototype  devices that were
        ordered  pursuant to Section 4.5 of this Agreement.  For purchase orders
        for units of Product,  if the written  notice is less than the  Purchase
        Order Lead Time, then a cancellation charge, as specified in Section 9.0
        of Attachment C, will immediately become due for each canceled unit.

11.2    For a purchase order for production units which is more than thirty (30)
        days,  but less than the  Purchase  Order  Lead Time from its  Scheduled
        Shipment Date,  Buyer may request in writing a one-time  deferral of the
        Scheduled  Shipment  Date for not more than  ninety  (90) days,  with no
        cancellation  charge  imposed.   However,  if  this  purchase  order  is
        subsequently   deferred  or  canceled,   then  the  cancellation  charge
        specified in Section 9.0 of Attachment C will be due.

        Specifications  as set forth in the RTM for the  applicable  period  set
        forth in  Attachment  C.  Delivery  to Buyer of each unit of  Product is
        deemed  to  occur  five  (5)  days  after   shipment  from  IBM.   Buyer
        acknowledges  that the  functionality  of  Products is  contingent  upon
        Buyer's designs and,  therefore,  the warranty of this Section 14.1 does
        not apply to the functionality of Products  fabricated  hereunder.  This
        warranty  does not include  repair of damage  resulting  from failure to
        provide a suitable installation  environment,  or any use for other than
        the   intended   purpose,   accident,    disaster,    neglect,   misuse,
        transportation, alterations, or non-IBM repairs or activities.

14.2    Any unit of Product  that fails to  conform to the  warranty  of Section
        14.1, while under warranty,  may be returned,  freight  collect,  to the
        location IBM  designates  for repair,  replacement  or credit,  at IBM's
        discretion,  provided,  however,  that IBM will  provide  a credit  upon
        Maker's  reasonable  request.  IBM will within a reasonable time, but no
        sooner than  Purchase  Order Lead Time  repair or replace  such units or
        provide a credit to Buyer for the purchase  price paid for such units by
        Buyer.  IBM will ship  replacement  units back to Buyer,  transportation
        prepaid  by IBM,  and such  units of Product  will be  considered  newly
        delivered for warranty purposes.

14.3    Should any unit of Product  returned to IBM hereunder be found by IBM to
        be free from defects or  non-conformities,  IBM will return such unit of
        Product to Buyer transportation prepaid by IBM. Payment for such unit of
        Product  will be due and  payable by Buyer as set forth in  Section  9.0
        above.

14.4    Prototypes  provided by IBM under this  Agreement are provided on an "AS
        IS" basis, without warranty of any kind.

14.5    No course of dealing, course of performance,  usage of trade, Product or
        Prototype  description shall be deemed to establish a warranty,  express
        or implied.

14.6    THE  FOREGOING  WARRANTIES  MADE BY IBM ARE EXCLUSIVE AND IN LIEU OF ANY
        OTHER WARRANTIES,  EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, THE
        IMPLIED  WARRANTIES  OF  MERCHANTABILITY  AND FITNESS  FOR A  PARTICULAR
        PURPOSE, AND ANY IMPLIED WARRANTIES OF NON-INFRINGEMENT.

15.0    CONFIDENTIAL INFORMATION

        All  information  exchanged under this Agreement is subject to the terms
        of the  separate  agreement  for  exchange of  confidential  information
        (Agreement  Number  V1424) as  executed  between the parties on December
        9,1996.

16.0    TRADEMARKS AND TRADE NAMES

16.1    Neither this  Agreement,  nor the sale of Products  hereunder,  shall be
        deemed  to  give  either  party  any  right  to use  the  other  party's
        trademarks or any of the other  party's  trade names  without  specific,
        prior written consent.

17.0    INTELLECTUAL PROPERTY RIGHTS

17.1    Buyer represents, and IBM acknowledges Buyer's representation,  that all
        Buyer  Deliverable  Items for the  Products  are the  property of Buyer.
        Buyer  represents and warrants it is the rightful  owner,  or authorized
        licensee  (with  all  requisite  rights  to  sublicense)  of  the  Buyer
        Deliverable  Items and all other  designs,  information,  and  materials
        supplied to IBM hereunder,  and that no part of such materials knowingly
        incorporate  or infringe the  intellectual  property of any third party.
        Buyer  and/or its  suppliers  shall  have and  retain  all  intellectual
        property rights associated with any intellectual  property  furnished by
        Buyer, but excluding any intellectual property furnished by or for IBM.

17.2    IBM or its  licensors  shall retain and have all  intellectual  property
        rights (including, without limitation, mask work rights) associated with
        any  intellectual  property  furnished  by IBM in  connection  with this
        Agreement, including without limitation, (i) all base array layers, (ii)
        all IBM-licensed  library elements (including,  without limitation,  any
        megafunctions or cores),  and (iii) all design  methodologies and tools,
        (iv) all  IBM-furnished  modifications  of any of the foregoing.  To the
        extent Buyer has access to such intellectual  property,  Buyer shall use
        such   intellectual   property  solely  for  the  purpose  of  designing
        Prototypes  and Products  for  manufacture  pursuant to this  Agreement.
        Buyer  hereby  conveys to IBM any  intellectual  property  rights it may
        acquire  therein.  IBM represents and warrants,  and Buyer  acknowledges
        IBM's  representation,  that IBM is the  rightful  owner  or  authorized
        licensee of all  intellectual  property  furnished by IBM in  connection
        with this Agreement.

17.3    IBM shall own any masks made by IBM using logic data  provided by Buyer.
        IBM will use any tangible netlist  tape(s),  and tangible GDS II tape(s)
        received from Buyer or generated  exclusively for Buyer  hereunder,  and
        any masks made from such GDS II tape(s),  only to  manufacture  Products
        for sale solely and exclusively to Buyer.

17.4    Except as set forth in section  17.2,  if in the  course of  performance
        under this  Agreement  either  party  discovers  or invents any process,
        pattern, device or other invention,  that party shall be deemed the sole
        owner of such discovery or invention. In the event any such invention is
        jointly  discovered  or invented by the  parties,  the parties  shall be
        deemed joint owners of such  discovery or invention  without any duty of
        accounting.

17.5    The  parties  understand  and agree that no  license  or other  right is
        granted herein to either party, directly or by implication,  estoppel or
        otherwise,  with respect to any  know-how,  inventions,  patents,  trade
        secrets,  copyrights,  mask works or other intellectual property rights,
        except as expressly set forth in this Agreement.  No additional  license
        or other right, express or implied, shall arise from the consummation of
        this Agreement, or from any acts, statements or dealings leading to such
        consummation.

18.0    INTELLECTUAL PROPERTY INDEMNIFICATION

18.1    IBM shall  indemnify  Buyer from and against any damages finally settled
        or  awarded  by a court of  competent  jurisdiction  resulting  from any
        direct infringement of any patents or copyrights of a third party in any
        country in which IBM sells  similar  products that expose IBM to similar
        liabilities  as the  Product,  arising  as a  result  of  any  of  IBM's
        manufacturing  process,  equipment or testing,  that is not specifically
        required by Buyer's designs,  specifications or instructions.  IBM shall
        defend at its own expense,  including  attorney's fees, any suit brought
        against  Buyer  alleging  such  infringement.  In the event  that  Buyer
        becomes  enjoined  from  using  Product  in its  inventory  due to  such
        infringement,  IBM at its option and expense,  will secure for Buyer the
        right to  continue to use and market the  Product,  or modify or replace
        the  Product  with a  non-infringing  product.  If IBM  determines  that
        neither of the foregoing alternatives is reasonably available, Buyer may
        return the  affected  Product in Buyer's  inventory  to IBM for a credit
        equal to the price  paid for the units of  Product  affected.  IBM shall
        have no obligation  regarding any claim based upon  modification  of the
        Product by Buyer or its customers,  use of the Product in other than its
        intended operating  environment or the combination,  operation or use of
        the Product with non-IBM products or equipment.

18.2    Buyer shall  indemnify IBM from and against any damages  finally settled
        or  awarded  by a court of  competent  jurisdiction  resulting  from any
        infringement  of any  patents  or  copyrights  of a third  party  in any
        country where Buyer uses or distributes the Product, arising as a result
        of  IBM's  compliance  with  any  of  Buyer's  design,   specifications,
        instructions or  modifications  of the Product by Buyer and shall defend
        at its own expense,  including attorney's fees, any suit brought against
        IBM alleging any such infringement.

18.3    The rights  provided in Sections 18.1 and 18.2 are  contingent  upon the
        parties  seeking to enforce  indemnification  by giving  prompt  written
        notice to the indemnifying  party regarding any claim,  demand or action
        for which the indemnified party seeks  indemnification.  The indemnified
        party is required to fully cooperate with the indemnifying  party at the
        indemnifying  party's expense and shall allow the indemnifying  party to
        control the defense or settlement  of any such claim,  demand or action,
        including  obtaining the written consent of the indemnifying party prior
        to any settlement  proposal or  settlement.  IBM shall have the right to
        waive  Buyer's  obligations  under  Section 18.2 and provide for its own
        defense, at IBM's sole discretion and expense.

18.4    The  purchase,  receipt or possession of the Product from or through IBM
        carries no license or immunity,  express or implied, under any patent of
        IBM covering the  combination  of the Product with other products or the
        use of any such combination,  or under any patent or other  intellectual
        property  right  of any  third  party  relating  to the  Product  or its
        combinations with any other products.

18.5    Except as expressly  stated in this Agreement,  this Section 18.0 states
        the entire  liability of the parties and their  exclusive  remedies with
        respect to infringement and all other warranties against infringement of
        any  intellectual  property  rights,  statutory,  express or implied are
        hereby disclaimed.

19.0    INDEPENDENT PARTIES

        Each party hereto is an  independent  contractor  and is not an agent of
        the other party for any purpose whatsoever. Neither party shall make any
        warranties or  representations on the other party's behalf, nor shall it
        assume or create any other obligations on the other party's behalf.  IBM
        and Buyer  agree to  indemnify  from and  against  any  damages  finally
        awarded  by  a  court  of  competent  jurisdiction  resulting  from  any
        violation of this Section 19.0.

20.0    LIMITATION OF REMEDIES

20.1    IBM's entire  liability  and Buyer's  exclusive  remedy are set forth in
        this Section:

        20.1.1 In all situations involving  non-conforming or defective Products
        furnished  under this  Agreement as set forth in Section  14.1,  Buyer's
        exclusive remedy is the replacement of the Products or a credit to Buyer
        of the purchase price paid for such units by Buyer, at IBM's discretion,
        provided,   however,  that  IBM  will  provide  a  credit  upon  Maker's
        reasonable request.

        20.1.2  IBM's  liability  for actual  damages  for any cause  whatsoever
        (other  than as set forth in Section  20.1 .1),  shall be limited to the
        greater of fifty thousand dollars ($50,000) or the applicable unit price
        for the  specific  units of Product  that caused the damages or that are
        the subject matter of, or are directly  related to, the cause of action.
        This limitation will apply,  except as otherwise stated in this Section,
        regardless  of the  form of  action,  whether  in  contract  or in tort,
        including  negligence.  This limitation will not apply to the payment of
        costs,  damages and  attorney's  fees referred to in Section 18.0.  This
        limitation  will also not apply to claims by Buyer for bodily  injury or
        damage to real property or tangible  personal  property  caused by IBM's
        negligence.

        20.1.3 In no event will  either  party be liable to the other  party for
        any  lost   profits,   lost   savings,   incidental   damages  or  other
        consequential  damages,  even  if  advised  of the  possibility  of such
        damages, except as provided in Section 18.0. In addition IBM will not be
        liable for any claim based on any third-party claim,  except as provided
        in Section 18.0.  In no event will IBM be liable for any damages  caused
        by  Buyer's  failure  to  perform  Buyer's  responsibilities.  

        20.1.4 In addition,  IBM shall have no  liability  when the Products are
        used in conjunction  with (a) any medical  implantation  or other direct
        life  support  applications  where  malfunction  may  result  in  direct
        physical harm or injury to persons or (b) commercial  aviation,  nuclear
        materials, or other ultra-hazardous activities.

21.0    SUBCONTRACT AND ASSIGNMENT

21.1    IBM has  the  right  to  subcontract  its  responsibilities  under  this
        Agreement,  provided that any subcontractor retained by IBM is obligated
        in writing to the same  obligations  as set forth herein with respect to
        IBM.  In the event that IBM does  subcontract  certain  portions  of its
        responsibilities,  the term "employee" as used herein shall be deemed to
        include such subcontractor and/or its employees.

21.2    Neither party to this  Agreement may assign its  obligations or delegate
        its duties in whole or in part without the prior written  consent of the
        other  except  that IBM may  assign  its  rights to  payment  under this
        Agreement  and if the  assets or stock of that  portion  of IBM to which
        this Agreement pertains hereafter becomes owned or controlled,  directly
        or indirectly,  by a third party, IBM may assign its entire right, title
        and  interest  in  this  Agreement  to  such  third  party.   Any  other
        assignments or delegations will be void.

22.0    COMPETITIVE PRODUCTS AND SERVICES

        Neither this  Agreement  nor any  activities  hereunder  will impair any
        right of IBM or Buyer to design, develop, manufacture,  market, service,
        or otherwise deal in, directly or indirectly, other products or services
        including  those  which are  competitive  with  those  offered by IBM or
        Buyer.

23.0    PROMOTIONAL ACTIVITY

        Press  releases and other like  publicity,  advertising  or  promotional
        material  which mention the other party by name,  this  Agreement or any
        term hereof shall be agreed upon by both parties in writing prior to any
        release.

24.0    FORCE MAJEURE

        Except for payments due IBM, neither party shall be in default or liable
        for any delay or failure of compliance with this Agreement due to an act
        of nature,  public enemy, freight embargo, or other cause if such act of
        nature,  public  enemy,  freight  embargo,  or other cause is beyond the
        control of the non-performing  party. A non-performing  party shall cure
        as soon as  practicable,  and as soon as  practicable  after  such force
        majeure event, notify the other party in writing of such event.

        regulations of the U.S. Government relating to the export of commodities
        and technical data insofar as they relate to the  activities  under this

        export  control laws and  regulations  of the United  States of America,
        including,  without limitation,  the U.S. Export  Administration Act and

        laws of the State of New York,  without  regard to the  conflict of laws
        principles thereof.  Buyer shall bring any and all actions arising under
        or relating to this Agreement  only in courts of competent  jurisdiction
        in the State of New York.  IBM shall bring any and all  actions  arising
        under  or  relating  to this  Agreement  only  in  courts  of  competent
        jurisdiction in the  Commonwealth of  Massachusetts.  The parties hereto
        expressly  waive any right  they may have to a jury trial and agree that
        any proceeding  under this Agreement shall be tried by a judge without a
        jury.

26.5    If any section or  subsection  of this  Agreement  is found by competent
        judicial  authority  to be  invalid,  illegal  or  unenforceable  in any
        respect,  the validity,  legality and enforceability of any such section
        or subsection in every other respect and the remainder of this Agreement
        shall  continue  in  effect  so long  as the  redacted  Agreement  still

        supplemented or modified by any course of dealing, course of performance
        or trade usage.  The term "this  Agreement" as used herein  includes any

        by the other to any term of this Agreement or failure by either party to

3.5 Licensee will not be obligated to provide PTL with Licensee's Modifications.
If  Licensee  provides  PTL with a copy of any  Modification,  unless  otherwise
agreed  in a  separate  writing  signed  by  authorized  representatives  of the
parties, Licensee will be deemed to have granted PTL a non-exclusive, perpetual,
worldwide,  royalty free license to use and sublicense any such Modification for
any purpose PTL deems fit.

3.6 PTL may include third party intellectual property in the Software.  PTL will

conditionally  reduce  Obligations,  but shall not be  considered  a payment  in
respect of the  Obligations  unless  such  payment is of  immediately  available
federal funds or unless

calculation  thereof all in reasonable  detail,  which statement shall be deemed
true and correct absent manifest error.

effective on the Closing Date and,  subject to Section 12.7,  shall  continue in
full  force  and  effect  for a term  ending  on the  Revolving  Maturity  Date.

<PAGE>

          (a) Declare all Obligations,  whether evidenced by this Agreement,  by
     any of the other Loan Documents, or otherwise,  immediately due and payable
     (provided  that upon the  occurrence  of an Event of Default  described  in
     Section  8.5 all  Obligations  shall  become  immediately  due and  payable
     without any action by Bank);

          (b) Cease advancing money or extending credit to or for the benefit of

     considers advisable;

     do such acts as Bank  considers  necessary  or  reasonable  to protect  its
     security  interest  in the  Collateral.  Borrower  agrees to  assemble  the
     Collateral  if Bank so requires,  and to make the  Collateral  available to
     Bank as Bank may designate.  Borrower authorizes Bank to enter the premises
     where the  Collateral  is located,  to take and maintain  possession of the
     Collateral, or any part of it, and to pay, purchase, contest, or compromise
     any encumbrance,  charge, or lien which in Bank's determination  appears to
     be prior or  superior  to its  security  interest  and to pay all  expenses
     incurred  in  connection  therewith.  With  respect  to any  of  Borrower's
     premises,  Borrower hereby grants Bank a license to enter such premises and

     or remedies provided herein, at law, in equity, or otherwise;

     Borrower held by Bank;

          (h) Ship, reclaim,  recover, store, finish; maintain,  repair, prepare
     for sale,  advertise for sale, and sell (in the manner provided for herein)

     license or other right,  solely  pursuant to the provisions of this Section

     as it pertains to the Collateral,  in completing production of, advertising
     for sale,  and  selling  any  Collateral  and,  in  connection  with Bank's

     licenses and all franchise agreements shall inure to Bank's benefit;

          (i) Sell the  Collateral  at either a public or private sale, or both,
     by way of one or more contracts or  transactions,  for cash or on terms, in
     such  manner and at such places  (including  Borrower's  premises)  as Bank
     determines is commercially  reasonable,  and apply the proceeds  thereof to
     the Obligations in whatever manner or order it deems appropriate;

          (j) Bank may credit bid and  purchase  at any public  sale,  or at any
     private sale as permitted by law; and

(and any of Bank's  designated  officers,  or employees) as Borrower's  true and
lawful  attorney to: (a) send  requests for  verification  of Accounts or notify
account  debtors  of Bank's  security  interest  in the  Accounts;  (b)  endorse
Borrower's  name on any checks or other  forms of payment or  security  that may
come into Banks  possession;  (c) sign Borrower's name on any invoice or bill of
lading relating to any Account,  drafts against account  debtors,  schedules and
assignments  of  Accounts,  verifications  of  Accounts,  and notices to account
debtors;  (d) make,  settle,  and  adjust all claims  under and  decisions  with
respect to Borrowers  policies of insurance;  and (e) settle and adjust disputes
and claims  respecting the accounts  directly with account debtors,  for amounts
and upon terms which Bank determines to be reasonable;  (f) to file, in its sole
discretion,  one or more  financing or  continuation  statements  and amendments
thereto,  relative to any of the  Collateral  without the  signature of Borrower
where  permitted by law;  provided  Bank may exercise  such power of attorney to
sign the name of Borrower on any of the documents described in


                                       16

appointment  of Bank as  Borrowers  attorney in fact,  and each and every one of
Banks rights and powers,  being coupled with an interest,  is irrevocable  until
all of  the  Obligations  have  been  fully  repaid  and  performed  and  Bank's
obligation to provide advances hereunder is terminated.

     9.3 Accounts Collection.  Upon the occurrence and during the continuance of

all  payments  as  Bank's  trustee,  and  if  requested  or  required  by  Bank,
immediately  deliver such  payments to Bank in their  original  form as received
from the account debtor, with proper endorsements for deposit

     9.4 Bank  Expenses.  If  Borrower  fails to pay any  amounts or furnish any
required  proof of payment due to third persons or entities,  as required  under
the terms of this Agreement,  then Bank may do any or all of the following:  (a)
make payment of the same or any part thereof (b) set up such reserves  under the
Committed  Revolving  Line as Bank  deems  necessary  to  protect  Bank from the
exposure created by such failure;  or (c) obtain and maintain insurance policies
of the type discussed in Section 6.6 of this Agreement, and take any action with
respect to such  policies as Bank deems prudent Any amounts so paid or deposited
by Bank shall  constitute  Bank Expenses,  shall be immediately due and payable,
and shall bear interest at the then applicable rate  hereinabove  provided,  and
shall  be  secured  by the  Collateral.  Any  payments  made by Bank  shall  not
constitute  an  agreement  by Bank to make  similar  payments in the future or a
waiver by Bank of any Event of Default under this Agreement

     9.5  Bank's  Liability  for  Collateral.  So  long as  Bank  complies  with
reasonable banking  practices,  Bank shall not in any way or manner be liable or
responsible for (a) the  safekeeping of the  Collateral;  (b) any loss or damage
thereto  occurring or arising in any manner or fashion  from any cause;  (c) any
diminution  in the  value  thereof  or (d) any act or  default  of any  carrier,
warehouseman, bailee, forwarding agency, or other person whomsoever. All risk of
loss, damage or destruction of the Collateral shall be borne by Borrower.

     9.6 Remedies  Cumulative.  Bank's rights and remedies under this Agreement,
the Loan Documents,  and all other  agreements  shall be cumulative.  Bank shall
have all other rights and remedies  not  expressly  set forth herein as provided
under the Code, by law, or in equity. No exercise by Bank of one right or remedy
shall be deemed an  election,  and no waiver by Bank of any Event of  Default on
Borrower's  part  shall be deemed a  continuing  waiver.  No delay by Bank shall
constitute a waiver, election, or acquiescence by it. No waiver by Bank shall be
effective  unless made in a written  document  signed on behalf of Bank and then
shall be effective  only in the specific  instance and for the specific  purpose
for which it was given.

     9.7 Demand:  Protest  Borrower  waives demand,  protest,  notice of protest

exclusive right to apply any and all such payments against the then due and

other notices and demands in connection with the delivery, acceptance,
performance, default or enforcement of this Note, as well as any applicable
statutes of limitations. No delay by Bank in exercising any power or right
hereunder shall operate as a waiver of any power or right. Time is of the
essence as to all obligations hereunder.

     This Note is issued pursuant to the Loan Agreement which shall govern the
rights and obligations of Borrower with respect to all obligations hereunder.

     This Note shall be deemed to be made under, and shall be construed in

               Revolving  Maturity Date provided that Borrowers Letter of Credit
               reimbursement  obligation  shall  be  secured  by cash  on  terms
               acceptable to Bank at any time after the Revolving  Maturity Date
               if the  term of this  Agreement  is not  extended  by  Bank.  All
               Letters of Credit shall be in form and  substance  acceptable  to
               Bank in its sole discretion and shall be subject to the terms and
               conditions  of Banks form of standard  Application  and Letter of
               Credit Agreement.

               (b) The obligation of Borrower to immediately  reimburse Bank for
               drawings   made  under  Letters  of  Credit  shall  be  absolute,
               unconditional and irrevocable, and shall be performed strictly in
               accordance  with the terms of this  Agreement and such Letters of
               Credit,  under  all  circumstances  whatsoever.   Borrower  shall
               indemnify,  defend, protect and hold Bank harmless from any loss,
               cost,  expense  or  liability,   including,  without  limitation,
               reasonable  attorneys' fees, arising out of or in connection with
               any Letters of Credit.

               (c)  Borrower  may  request  that  Bank  issue a Letter of Credit
               payable in a currency  other than  United  States  Dollars.  If a
               demand for payment is made under any such Letter of Credit,  Bank
               shall  treat  such  demand  as an  Advance  to  Borrower  of  the
               equivalent of the amount  thereof (plus cable  charges) in United
               States  currency at the then  prevailing  rate of exchange in San

               transfer to the country of which it is the currency.

               (d) Upon the  issuance  of any  Letter  of  Credit  payable  in a
               currency  other than United States  Dollars,  Bank shall create a
               reserve under the Committed  Revolving Line for letters of credit
               against  fluctuations  in currency  exchange  rates, in an amount
               equal to ten  percent  (10%) of the face amount of such Letter of
               Credit  (the  "Letter  of Credit  Reserve").  The  amount of such
               Letter of Credit Reserve may be amended by Bank from time to time
               to  account  for   fluctuations   in  the  exchange   rate.   The
               availability of funds under the Committed Revolving Line shall be
               reduced by the  amount of such  Letter of Credit  Reserve  for so
               long as such Letter of Credit remains outstanding.

          15.  The   Borrower   shall   execute   and   deliver   to  the   Bank

               Agreement each of the following instruments in form and substance
               acceptable  to the Bank:  (i) an Amended and  Restated  Revolving
               Promissory Note in the original  principal  amount of Two Million
               Five Hundred Thousand Dollars ($2,500,000.00),  (ii) an Equipment
               Line  Promissory  Note in the  original  principal  amount of One
               Million  Dollars  ($1,000,000.00),  and (iii) an  Equipment  Line
               Promissory  Note  dated  as of  May  12,  1998  in  the  original
               principal  amount of One Million  Five Hundred  Thousand  Dollars
               ($1,500,000.00).

          16.  The Borrowing Base Certificate appearing as Exhibit C to the Loan
               Agreement  is hereby  replaced  with the  Compliance  Certificate
               attached as Exhibit A hereto.

          17.  The  Compliance  Certificate  appearing  as Exhibit D to the Loan
               Agreement  is hereby  replaced  with the  Compliance  Certificate
               attached as Exhibit B hereto.

4. FEE.  Borrower shall pay to Bank a modification  fee equal to Eleven Thousand
Two  Hundred  Fifty  Dollars  ($11,250.00),  which  fee shall be due on the date
hereof and shall be deemed fully earned as of the date hereof.

5. CONSISTENT  CHANGES.  The Existing Loan Documents are hereby amended wherever
necessary to reflect the changes described above.

6.  RATIFICATION OF LOAN  DOCUMENTS.  Borrower hereby  ratifies,  confirms,  and
reaffirms all terms and conditions of all security or other  collateral  granted
to the Bank,  and  confirms  that the  indebtedness  secured  thereby  includes,
without limitation, the Indebtedness.

7. NO DEFENSE OF  BORROWER.  Borrower  agrees that,  as of this date,  it has no
defenses against the obligations to pay any amounts under the Indebtedness.

8. CONTINUING  VALIDITY.  Borrower  understands and agrees that in modifying the
existing   Indebtedness,   Bank  is  relying  upon  Borrower's  representations,
warranties, and agreements, as set forth in the Existing Loan Documents.  Except
as expressly modified pursuant to this Loan Modification Agreement, the terms of
the  Existing  Loan  Documents  remain  unchanged  and in full force and effect.
Bank's agreement to modifications to the existing  Indebtedness pursuant to this
Loan  Modification  Agreement in no way shall  obligate  Bank to make any future
modifications to the Indebtedness.  Nothing in this Loan Modification  Agreement
shall constitute a satisfaction of the Indebtedness. It is the intention of Bank
and Borrower to retain as liable parties all makers of Existing Loan  Documents,
unless the party is  expressly  released  by Bank in  writing.  No maker will be
released by virtue of this Loan Modification Agreement.

9.  JURISDICTION/VENUE.  Borrower  accepts for itself and in connection with its
properties,  unconditionally,  the  non-exclusive  jurisdiction  of any state or
federal court of competent  jurisdiction in the Commonwealth of Massachusetts in
any action, suit, or proceeding of any kind against it which arises out of or by
reason of this Loan Modification Agreement;  provided,  however, that if for any
reason  Bank  cannot  avail  itself  of  the  courts  of  the   Commonwealth  of
Massachusetts, then venue shall lie in Santa Clara County, California.

10.  COUNTERSIGNATURE.  This Loan Modification  Agreement shall become effective
only when it shall have been executed by Borrower and Bank  (provided,  however,
in no event shall this Loan Modification Agreement become effective until signed
by an officer of Bank in California).

                         EQUIPMENT LINE PROMISSORY NOTE

$1,500,000.00                                        ____________, Massachusetts
                                                     May 12, 1998


     FOR VALUE RECEIVED, the undersigned, MAKER COMMUNICATIONS, INC., a Delaware
corporation (the "Borrower"), promises to pay to the order of Silicon Valley
Bank, a California-chartered bank ("Bank") at such place as the holder hereof
may designate, in lawful money of the United States of America, the aggregate
unpaid principal amount of all advances ("Equipment Advances") made by Bank to
Borrower in accordance with the terms of the Loan and Security Agreement between
Borrower and Bank dated as of February 18, 1997, as amended by a Loan
Modification Agreement of even date herewith, as may be further amended from
time to time (as amended, the "Loan Agreement"), up to a maximum principal
amount of ONE MILLION FIVE HUNDRED THOUSAND AND NO/1OOTHS Dollars
($1,500,000.00), until paid in full. Borrower shall also pay interest on the
aggregate unpaid principal amount of such Equipment Advances at the rates and in
accordance with the terms of the Loan Agreement. The entire principal amount and
all accrued interest shall be due and payable on May 5, 2002.

     Borrower irrevocably waives the right to direct the application of any and
all payments at any time hereafter received by Bank from or on behalf of
Borrower, and Borrower irrevocably agrees that Bank shall have the continuing
exclusive right to apply any and all such payments against the then due and
owing obligations of Borrower as Bank may deem advisable. In the absence of a
specific determination by Bank with respect thereto, all payments shall be
applied in the following order: (a) then due and payable fees and expenses; (b)
then due and payable interest payments and mandatory prepayments; and (c) then
due and payable principal payments and optional prepayments.

     Bank is hereby authorized by Borrower to endorse on Bank's books and
records each Equipment Advance made by Bank under this Note and the amount of
each payment or prepayment of principal of each such Equipment Advance received
by Bank; it being understood, however, that failure to make any such endorsement
(or any error in notation) shall not affect the obligations of Borrower with
respect to Equipment Advances made hereunder, and payments of principal by
Borrower shall be credited to Borrower notwithstanding the failure to make a
notation (or any errors in notation) thereof on such books and records.

     Borrower promises to pay Bank all costs and expenses of collection of this
Note and to pay all reasonable attorneys' fees incurred in such collection,
whether or not there is a suit or action, or in any suit or action to collect
this Note or in any appeal thereof. Borrower waives presentment, demand,
protest, notice of protest, notice of dishonor, notice of nonpayment, and any
and all other notices and demands in connection with the delivery, acceptance,
performance, default or enforcement of this Note, as well as any applicable
statutes of limitations. No delay by Bank in exercising any power or right
hereunder shall operate as a waiver of any power or right. Time is of the
essence as to all obligations hereunder.

     This Note is issued pursuant to the Loan Agreement, which shall govern the
rights and obligations of Borrower with respect to all obligations hereunder.

                           MAKER COMMUNICATIONS, INC.

                            1999 STOCK INCENTIVE PLAN

                             1. Purpose of the Plan.

     This stock plan (the "Plan") is intended to provide incentives: (a) to the
employees of Maker Communications, Inc. (the "Company") and any present or
future subsidiaries of the Company by providing them with opportunities to
purchase stock in the Company pursuant to options granted hereunder which
qualify as "incentive stock options" under Section 422 of the Internal Revenue
Code of 1986, as amended (the "Code") ("ISO" or "ISOs"); and (b) to officers,
employees, consultants and directors of the Company and any subsidiaries by
providing them with opportunities to purchase stock in the Company pursuant to
options granted hereunder which do not qualify as ISOs ("Non-Qualified Option"
or "Non-Qualified Options"). As used herein, the terms "parent" and "subsidiary"
mean "parent corporation" and "subsidiary corporation," respectively, as those
terms are defined in Section 424 of the Code and the Treasury Regulations
promulgated thereunder (the "Regulations").

     2. Stock Subject to the Plan.

     (a) The initial maximum number of shares of common stock, par value $.01
per share, of the Company ("Common Stock") available for stock options and stock
awards granted under the Plan through the end of the Company's fiscal year
ending December 31, 1999 shall be 2,600,000 shares of Common Stock. In addition,
effective January 1, 2000 and each January 1 thereafter during the term of this
Plan, the number of shares of Common Stock available for grants of stock options
and stock awards made after such January 1 under this Plan shall be increased
automatically by an amount equal to (i) 5% of the total issued and outstanding
shares of Common Stock (rounded to the nearest whole share and calculated on a
fully diluted basis, that is assuming the exercise of all outstanding options to
purchase Common Stock and warrants to purchase Common Stock) as of the close of
business on December 31 of the preceding year or (ii) a lesser amount as
determined by the Board of Directors. The Board of Directors shall initially
reserve for issuance under this Plan 2,600,000 shares of Common Stock. Effective
January 1, 2000 and effective on each succeeding January 1 thereafter during the
term of this Plan, the Board of Directors shall reserve for issuance under this
Plan such number of shares of Common Stock as is equal to the sum of (i) the
number of shares of Common Stock issuable upon the exercise of options then
outstanding under the Plan; and (ii) the number of shares of Common Stock
resulting from the calculation set forth in the second sentence of this
paragraph. The maximum number of shares of Common Stock available for grants
shall be subject to adjustment in accordance with Section 12 hereof. Shares
issued under the Plan may be authorized but unissued shares of Common Stock or
shares of Common Stock held in treasury.

     (b) To the extent that any stock option shall lapse, terminate, expire or
otherwise be canceled without the issuance of shares of Common Stock, or any
stock award is settled in cash, the shares of Common Stock covered by such
option(s) or award shall again be available for the granting of stock options or
awards.


<PAGE>

           (c) Common Stock issuable under the Plan may be subject to such
restrictions on transfer, repurchase rights or other restrictions as shall be
 determined by the Committee (as defined in Section 3 below).

        3. Stock Awards.

        (a) The Committee may grant, subject to the limitation on the number of
shares of Common Stock available under Section 2 hereof, stock awards to
employees of and other key individuals engaged to provide services to the
Company and its subsidiaries. A stock award may be made in stock or denominated
in stock subject to final settlement in cash or stock. Each stock award granted
shall be subject to such terms and conditions as the Committee, in its sole
discretion, shall determine and establish. These may include, but are not
limited to, establishing a holding period during which stock issued pursuant to
an award may not be transferred, requiring forfeiture of the stock award because
of termination of employment or failure to achieve specific objectives such as
measures of individual, business unit or Company performance, including stock
price appreciation. In determining a person's eligibility to be granted an
award, as well as in determining the number of shares to be awarded to any
person, the Committee shall take into account the person's position and
responsibilities, the nature and value to the Company or its subsidiaries of
such person's service and accomplishments, such person's present and potential
contribution to the success of the Company or its subsidiaries, and such other
factors as the Committee may deem relevant.

        (b) The Committee may provide that a stock award earn dividends or
dividend equivalents, which may be paid currently or may be deferred in payment,
including reinvestment in additional shares covered by the applicable stock
award, all on such terms and conditions as the Committee shall deem appropriate.

        (c) The Committee shall require that for any stock award to be
effective, the recipient of the award shall execute an Award Agreement at such
time and in such form as the Committee shall determine. Any Award Agreement may
require that for any or some of the shares issued, the awardee must pay a
minimum consideration, whether in cash, property or services, as may be required
by applicable law or the Committee, as the Committee shall determine.

        (d) A stock award may be granted singly or in combination or in tandem
with another stock award or stock option. A stock award may also be granted as
the payment form in settlement of a grant or right under any other Company
employee benefit or compensation plan, including the plan of an acquired entity.

        (e) Directors who are not otherwise employees of the Company or a
subsidiary shall not be eligible to receive stock awards pursuant to the Plan.

        (f) No award granted to any person under the Plan shall be assignable or
transferable otherwise than by will or the laws of descent and distribution. Any
award granted under the Plan

                                      - 2 -

<PAGE>

shall be null and void and without effect upon any attempted assignment or
transfer, except as herein provided, including without limitation any purported
assignment, whether voluntary or by operation of law, pledge, hypothecation or
other disposition, attachment, trustee process or similar process, whether legal
or equitable, upon such award.

     4. Administration of the Plan.

     (a) At the discretion of the Company's Board of Directors, the Plan shall
be administered either (i) by the full Board of Directors of the Company or (ii)
by a committee (the "Committee") consisting of two or more members of the
Company's Board of Directors. In the event the full Board of Directors is the
administrator of the Plan, references herein to the Committee shall be deemed to
include the full Board of Directors. The Board of Directors may from time to
time appoint a member or members of the Committee in substitution for or in
addition to the member or members then in office and may fill vacancies on the
Committee however caused. The Committee shall choose one of its members as
Chairman and shall hold meetings at such times and places as it shall deem
advisable. A majority of the members of the Committee shall constitute a quorum
and any action may be taken by a majority of those present and voting at any
meeting.

        (b) Any action may also be taken without the necessity of a meeting by a
written instrument signed by a majority of the Committee. The decision of the
Committee as to all questions of interpretation and application of the Plan
shall be final, binding and conclusive on all persons. The Committee shall have
the authority to adopt, amend and rescind such rules and regulations as, in its
opinion, may be advisable in the administration of the Plan. The Committee may
correct any defect or supply any omission or reconcile any inconsistency in the
Plan or in any option agreement granted hereunder in the manner and to the
extent it shall deem expedient to carry the Plan into effect and shall be the
sole and final judge of such expediency. No Committee member shall be liable for
any action or determination made in good faith.

        (c) Subject to the terms of the Plan, the Committee shall have the
authority to (i) determine the employees of the Company and its subsidiaries
(from among the class of employees eligible under Section 5 to receive ISOs) to
whom ISOs may be granted, and to determine (from the class of individuals
eligible under Section 5 to receive Non-Qualified Options) to whom Non-Qualified
Options may be granted; (ii) determine the time or times at which options may be
granted; (iii) determine the option price of shares subject to each option which
price shall not be less than the minimum price specified in Section 7; (iv)
determine whether each option granted shall be an ISO or a Non-Qualified Option;
(v) determine (subject to Section 10) the time or times when each option shall
become exercisable and the duration of the exercise period; (vi) determine
whether restrictions such as repurchase options are to be imposed on shares
subject to options and the nature of such restrictions; and (vii) determine the
size of any Options under the Plan, taking into account the position or office
of the optionee with the Company, the job performance of the optionee and such
other factors as the Committee may deem relevant in the good faith exercise of
its independent business judgment. Subject to the

                                      -3-
<PAGE>

provisions of Section 3 the Committee shall also have the authority to grant
stock awards under this Plan.

        5. Options.

        Options designated as ISOs may be granted only to employees of the
Company or any subsidiary. Non-Qualified Options may be granted to any officer,
employee, consultant or director of the Company or of any of its subsidiaries.
"Subsidiary" or "subsidiaries" shall be as defined in Section 424 of the Code
and the Treasury Regulations promulgated thereunder (the "Regulations") and
shall include subsidiaries which became such after adoption of the Plan.

        In determining the eligibility of an individual to be granted an option,
as well as in determining the number of shares to be optioned to any individual,
the Committee shall take into account the position and responsibilities of the
individual being considered, the nature and value to the Company or its
subsidiaries of his or her service and accomplishments, his or her present and
potential contribution to the success of the Company or its subsidiaries, and
such other factors as the Committee may deem relevant.

        No option designated as an ISO shall be granted to any employee of the
Company or any subsidiary if such employee owns, immediately prior to the grant
of an option, stock representing more than 10% of the combined voting power of
all classes of stock of the Company or a parent or a subsidiary, unless the
purchase price for the stock under such option shall be at least 110% of its
fair market value at the time such option is granted and the option, by its
terms, shall not be exercisable more than five years from the date it is
granted. In determining the stock ownership under this paragraph, the provisions
of Section 424(d) of the Code shall be controlling. In determining the fair
market value under this paragraph, the provisions of Section 7 hereof shall
apply.

        The maximum number of shares of the Company's Common Stock with respect
to which an option or options may be granted to any employee in any calendar
year shall not exceed 500,000 shares, taking into account shares subject to
options granted and terminated, or repriced, during such calendar year.

        6. Option Agreement.

        Each option shall be evidenced by an option agreement (the "Agreement")
duly executed on behalf of the Company and by the optionee to whom such option
is granted, which Agreement shall comply with and be subject to the terms and
conditions of the Plan. The Agreement may contain such other terms, provisions
and conditions which are not inconsistent with the Plan as may be determined by
the Committee, provided that options designated as incentive stock options shall
meet all of the conditions for incentive stock options as defined in Section 422
of the Code. The date of grant of an option shall be as determined by the
Committee. More than one option may be granted to an individual.


                                      -4-
<PAGE>

        7. Option Price.

        The option price or prices of shares of the Company's Common Stock for
options designated as non-qualified stock options shall be determined by the
Committee, but in no event shall the option price of a non-qualified stock
option be less than the par value of such Common Stock at the time the option is
granted. The option price or prices of shares of the Company's Common Stock for
incentive stock options shall be no less than the fair market value of such
Common Stock at the time the option is granted as determined bym the Committee
in accordance with Section 422 of the Code and the Regulations promulgated
thereunder. If such shares are then listed on any national securities exchange,
the fair market value shall be the mean between the high and low sales prices,
if any, on the largest such exchange on the date of the grant of the option or,
if none, shall be determined by taking a weighted average of the means between
the highest and lowest sales prices on the nearest date before and the nearest
date after the date of grant in accordance with Treasury Regulations Section
25.2512-2. If the shares are not then listed on any such exchange, the fair
market value of such shares shall be the mean between the high and low sales
prices, if any, as reported in the National Association of Securities Dealers
Automated Quotation National Market ("NASDAQ/NM") for the date of the grant of
the option, or, if none, shall be determined by taking a weighted average of the
means between the highest and lowest sales on the nearest date before and the
nearest date after the date of grant in accordance with Treasury Regulations
Section 25.2512-2. If the shares are not then either listed on any such exchange
or quoted in NASDAQ/NM, the fair market value shall be the mean between the
average of the "Bid" and the average of the "Ask" prices, if any, as reported in
the National Daily Quotation Service for the date of the grant of the option,
or, if none, shall be determined by taking a weighted average of the means
between the highest and lowest sales prices on the nearest date before and the
nearest date after the date of grant in accordance with Treasury Regulations
Section 25.2512-2. If the fair market value cannot be determined under the
preceding three sentences, it shall be determined in good faith by the
Committee.

        8. Manner of Payment; Manner of Exercise.

        (a) The option agreement may provide for the payment of the exercise
price by delivery of (i) cash or a check payable to the order of the Company in
an amount equal to the exercise price of such options, (ii) shares of Common
Stock of the Company owned by the optionee having a fair market value equal in
amount to the exercise price of the options being exercised, or (iii) any
combination of (i) and (ii), provided, however, that payment of the exercise
price by delivery of shares of Common Stock of the Company owned by such
optionee may be made only if such payment does not result in a charge to
earnings for financial accounting purposes as determined by the Committee. The
fair market value of any shares of the Company's Common Stock which may be
delivered upon exercise of an option shall be determined by the Committee in
accordance with Section 7 hereof. With the consent of the Committee, payment may
also be made by delivery of a properly executed exercise notice to the Company,
together with a copy of irrevocable instruments to a broker to deliver promptly
to the Company the


                                      -5-
<PAGE>

amount of sale or loan proceeds to pay the exercise price. To facilitate the
foregoing, the Company may enter into agreements for coordinated procedures with
one or more brokerage firms.

        (b) To the extent that the right to purchase shares under an option has
accrued and is in effect, options may be exercised in full at one time or in
part from time to time, by giving written notice, signed by the person or
persons exercising the option, to the Company, stating the number of shares with
respect to which the option is being exercised, accompanied by payment in full
for such shares as provided in subparagraph (a) above. Upon such exercise,
delivery of a certificate for paid-up non-assessable shares shall be made at the
principal office of the Company to the person or persons exercising the option
at such time, during ordinary business hours, not earlier than ten business days
from the date of receipt of the notice by the Company, as shall be designated in
such notice, or at such time, place and manner as may be agreed upon by the
Company and the person or persons exercising the option.

        9. Exercise of Options.

        Each option granted under the Plan shall, subject to Section 10(b) and
Section 12 hereof, be exercisable at such time or times and during such period
as shall be set forth in the Agreement; provided, however, that no incentive
stock option granted under the Plan shall have a term in excess of ten (10)
years from the date of grant, and no non-qualified stock option granted under
the Plan shall have a term in excess of ten (10) years from the date of grant.

           To the extent that an option to purchase shares is not exercised by
an optionee when it becomes initially exercisable, it shall not expire but shall
be carried forward and shall be exercisable, on a cumulative basis, until the
expiration of the exercise period. No partial exercise may be made for less than
two hundred fifty (250) full shares of Common Stock.

        10. Term of Options; Exercisability.

        (a) Term.

            (1) Each incentive stock option shall expire not more than ten (10)
        years from the date of the granting thereof, but shall be subject to
        earlier termination as herein provided. Each non-qualified stock option
        shall expire not more than ten (10) years from the date of the granting
        thereof, but shall be subject to earlier termination as herein provided.

            (2) Except as otherwise provided in this Section 10, an option
        granted to any employee optionee who ceases to be an employee of the
        Company or one of its subsidiaries shall terminate seven days after the
        date such optionee ceases to be an employee of the Company or one of its
        subsidiaries, or on the date on which the option expires by its terms,
        whichever occurs first.


                                      -6-
<PAGE>

            (3) If such termination of employment is because of dismissal for
        cause or because the employee is in breach of any employment agreement,
        such option will terminate immediately on the date the optionee ceases
        to be an employee of the Company or one of its subsidiaries.

            (4) If such termination of employment is because the optionee has
        become permanently disabled (within the meaning of Section 22(e)(3) of
        the Code), such option shall terminate on the last day of the twelfth
        month from the date such optionee ceases to be an employee, or on the
        date on which the option expires by its terms, whichever occurs first.

            (5) In the event of the death of any optionee, any option granted to
        such optionee shall terminate on the last day of the twelfth month from
        the date of death, or on the date on which the option expires by its
        terms, whichever occurs first.

            (6) Notwithstanding subparagraphs (2), (3), (4) and (5) above, the
        Committee shall have the authority to extend the expiration date of any
        outstanding option in circumstances in which it deems such action to be
        appropriate, provided that no such extension shall extend the term of an
        option beyond the date on which the option would have expired if no
        termination of the optionee's employment had occurred.

        (b) Exercisability.

            (1) An option granted to an employee optionee who ceases to be an
        employee of the Company or one of its subsidiaries for any reason shall
        be exercisable only to the extent that the right to purchase shares
        under such option has accrued and is vested and is in effect on the date
        such optionee ceases to be an employee of the Company or one of its
        subsidiaries.

            (2) In the event of the death of any optionee, the option granted to
        such optionee may be exercised by the estate of such optionee, or by any
        person or persons who acquired the right to exercise such option by
        bequest or inheritance or by reason of the death of such optionee.

        11. Transferability.

        The right of any optionee to exercise any option granted to him or her
shall not be assignable or transferable by such optionee otherwise than by will
or the laws of descent and distribution. ISOs shall be exercisable during the
lifetime of such optionee only by him/her. Any option granted under the Plan
shall be null and void and without effect upon the bankruptcy of the optionee to
whom the option is granted, or upon any attempted assignment or transfer, except
as herein provided, including without limitation any purported assignment,
whether

                                      -7-
<PAGE>

voluntary or by operation of law, pledge, hypothecation or other disposition,
attachment, divorce, trustee process or similar process, whether legal or
equitable, upon such option.

        12. Recapitalizations, Reorganizations and the Like.

        (a) In the event that the outstanding shares of the Common Stock of the
Company are changed into or exchanged for a different number or kind of shares
or other securities of the Company or of another corporation by reason of any
reorganization, merger, consolidation, recapitalization, reclassification, stock
split-up, combination of shares, or dividends payable in capital stock,
appropriate adjustment shall be made in the number and kind of shares as to
which options and stock awards may be granted under the Plan and as to which
outstanding options or awards or portions thereof then unexercised shall be
exercisable, to the end that the proportionate interest of the optionee or award
recipient shall be maintained as before the occurrence of such event; such
adjustment in outstanding options shall be made without change in the total
price applicable to the unexercised portion of such options and with a
corresponding adjustment in the option price per share.

        (b) In addition, unless otherwise determined by the Committee in its
sole discretion, in the case of any (i) sale or conveyance to another entity of
all or substantially all of the property and assets of the Company or (ii)
Change in Control (as hereinafter defined) of the Company, the purchaser(s) of
the Company's assets or stock may, in his, her or its discretion, deliver to the
optionee the same kind of consideration that is delivered to the shareholders of
the Company as a result of such sale, conveyance or Change in Control, or the
Committee may cancel all outstanding options in exchange for consideration in
cash or in kind, which consideration in both cases shall be equal in value to
the value of those shares of stock or other securities the optionee would have
received had the option been exercised (to the extent then exercisable) and no
disposition of the shares acquired upon such exercise been made prior to such
sale, conveyance or Change in Control, less the option price therefor. Upon
receipt of such consideration by the optionee, his or her option shall
immediately terminate and be of no further force and effect. The value of the
stock or other securities the optionee would have received if the option had
been exercised shall be determined in good faith by the Committee of the
Company, and in the case of shares of the Common Stock of the Company, in
accordance with the provisions of Section 7 hereof. The Committee shall also
have the power and right to accelerate the exercisability of any options,
notwithstanding any limitations in this Plan or in the Agreement upon such a
sale, conveyance or Change in Control, and in any event the exercisability of
options due to vest during the following twelve (12) month period shall
automatically be accelerated. Upon such acceleration, any options or portion
thereof originally designated as incentive stock options that no longer qualify
as incentive stock options under Section 422 of the Code as a result of such
acceleration shall be redesignated as non-qualified stock options. To the extent
permitted by law, upon such a sale, conveyance or a Change of Control the
Committee may, in its sole discretion, amend any Award Agreement issued under
the Plan in such manner as it deems appropriate, including without limitation,
by amendments that advance the dates upon which any or all

                                      -8-
<PAGE>

outstanding awards shall become free of restrictions or shall become issued or
payable, or that advance the dates upon which any or all outstanding awards
shall terminate.

        A "Change in Control" shall be deemed to have occurred if any person, or
any two or more persons acting as a group, and all affiliates of such person or
persons, who prior to such time owned less than fifty percent (50%) of the then
outstanding Common Stock of the Company, shall acquire such additional shares of
the Company's Common Stock in one or more transactions, or series of
transactions, such that following such transaction or transactions, such person
or group and affiliates beneficially own fifty percent (50%) or more of the
Company's Common Stock outstanding.

        (c) Upon dissolution or liquidation of the Company, all options granted
under this Plan shall terminate, but each optionee (if at such time in the
employ of or otherwise associated with the Company or any of its subsidiaries)
shall have the right, immediately prior to such dissolution or liquidation, to
exercise his or her option to the extent then exercisable. The Committee shall
have the right to accelerate the vesting of any award or take such other action
with respect thereto as the Committee shall in its sole discretion determine in
the event of any contemplated dissolution or liquidation of the Company.

        (d) No fraction of a share shall be purchasable or deliverable upon the
exercise of any option or stock award, but in the event any adjustment hereunder
of the number of shares covered by the option or award shall cause such number
to include a fraction of a share, such fraction shall be adjusted to the nearest
smaller whole number of shares.

     13. No Special Employment Rights.

     Nothing contained in the Plan or in any option granted under the Plan shall
confer upon any option holder any right with respect to the continuation of his
employment by the Company (or any subsidiary) or interfere in any way with the
right of the Company (or any subsidiary), subject to the terms of any separate
employment agreement to the contrary, at any time to terminate such employment
or to increase or decrease the compensation of the option holder from the rate
in existence at the time of the grant of an option. Whether an authorized leave
of absence, or absence in military or government service, shall constitute
termination of employment shall be determined by the Committee at the time.

        14. Withholding.

        The Company's obligation to deliver shares upon settlement of an award
or upon the exercise of any option granted under the Plan, or to make any cash
payment in connection with an award, and any payments or transfers under Section
12 hereof, shall be subject to the option or award holder's satisfaction of all
applicable Federal, state and local governmental tax withholding requirements.
Whenever cash is to be paid pursuant to an award under the Plan, the Company
shall be entitled to deduct therefrom an amount sufficient in its opinion to
satisfy all

                                       -9-
<PAGE>

federal, state and local tax withholding requirements related to such payment.
Whenever shares of Common Stock are to be delivered pursuant to an award or the
exercise of an option under the Plan, the Company shall be entitled to require
as a condition of delivery that the option or award holder remit to the Company
an amount sufficient in the opinion of the Company to satisfy all federal, state
and local governmental tax withholding requirements related thereto. With the
approval of the Committee, which it shall have sole discretion to grant, and on
such terms and conditions as the Committee may impose, the option or award
holder may satisfy the foregoing condition by electing to have the Company
withhold from delivery shares having a value equal to the amount of tax to be
withheld. The Committee shall also have the right to require that shares be
withheld from delivery to satisfy such condition.

        15. Restrictions on Issue of Shares.

        (a) Notwithstanding the provisions of Section 8, the Company may delay
the issuance of shares covered by the exercise of an option and the delivery of
a certificate for such shares until one of the following conditions shall be
satisfied:

                (i) The shares with respect to which such option has been
exercised are at the time of the issue of such shares effectively registered or
qualified under applicable Federal and state securities acts now in force or as
hereafter amended; or

                (ii) Counsel for the Company shall have given an opinion, which
opinion shall not be unreasonably conditioned or withheld, that such shares are
exempt from registration and qualification under applicable Federal and state
securities acts now in force or as hereafter amended.

        (b) It is intended that all exercises of options shall be effective, and
the Company shall use its best efforts to bring about compliance with the above
conditions within a reasonable time, except that the Company shall be under no
obligation to qualify shares or to cause a registration statement or a
post-effective amendment to any registration statement to be prepared for the
purpose of covering the issue of shares in respect of which any option may be
exercised, except as otherwise agreed to by the Company in writing.

        16. Purchase for Investment; Rights of Holder on Subsequent
Registration.

        Unless the shares to be issued upon exercise of an option granted under
the Plan have been effectively registered under the Securities Act of 1933, as
now in force or hereafter amended, the Company shall be under no obligation to
issue any shares covered by any option unless the person who exercises such
option, in whole or in part, shall give a written representation and undertaking
to the Company which is satisfactory in form and scope to counsel for the
Company and upon which, in the opinion of such counsel, the Company may
reasonably rely, that he or she is acquiring the shares issued pursuant to such
exercise of the option for his or her own account as an investment and not with
a view to, or for sale in

                                      -10-
<PAGE>

connection with, the distribution of any such shares, and that he or she will
make no transfer of the same except in compliance with any rules and regulations
in force at the time of such transfer under the Securities Act of 1933, or any
other applicable law, and that if shares are issued without such registration, a
legend to this effect may be endorsed upon the securities so issued. In the
event that the Company shall, nevertheless, deem it necessary or desirable to
register under the Securities Act of 1933 or other applicable statutes any
shares with respect to which an option shall have been exercised, or to qualify
any such shares for exemption from the Securities Act of 1933 or other
applicable statutes, then the Company may take such action and may require from
each optionee such information in writing for use in any registration statement,
supplementary registration statement, prospectus, preliminary prospectus or
offering circular as is reasonably necessary for such purpose and may require
reasonable indemnity to the Company and its officers and directors and
controlling persons from such holder against all losses, claims, damages and
liabilities arising from such use of the information so furnished and caused by
any untrue statement of any material fact therein or caused by the omission to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading in the light of the circumstances under which
they were made.

        17. Loans.

        The Company may not make loans to optionees to permit them to exercise
options.

        18. Modification of Outstanding Options.

        The Committee may authorize the amendment of any outstanding option with
the consent of the optionee when and subject to such conditions as are deemed to
be in the best interests of the Company and in accordance with the purposes of
this Plan.

        19. Approval of Shareholders.

        The Plan shall be subject to approval by the vote of shareholders
holding at least a majority of the voting stock of the Company voting in person
or by proxy at a duly held shareholders' meeting, or by written consent of
shareholders holding at least a majority of the voting stock of the Company,
within twelve (12) months after the adoption of the Plan by the Board of
Directors and shall take effect as of the date of adoption by the Board of
Directors upon such approval. The Committee may grant options under the Plan
prior to such approval, but any such option shall become effective as of the
date of grant only upon such approval and, accordingly, no such option may be
exercisable prior to such approval.

        20. Termination and Amendment.

        Unless sooner terminated as herein provided, the Plan shall terminate
ten (10) years from the date upon which the Plan was duly adopted by the Board
of Directors of the Company. The Board of Directors may at any time terminate
the Plan or make such modification or amendment

                                      -11-
<PAGE>

thereof as it deems advisable; provided, however, that except as provided in
this Section 20, the Board of Directors may not, without the approval of the
shareholders of the Company obtained in the manner stated in Section 19,
increase the maximum number of shares for which options may be granted or change
the designation of the class of persons eligible to receive options under the
Plan. The Committee may terminate, amend or modify any outstanding option
without the consent of the option holder, provided, however, that, except as
provided in Section 12, without the consent of the optionee, the Committee shall
not change the number of shares subject to an option, nor the exercise price
thereof, nor extend the term of such option, or make any other change in the
Plan which requires stockholder approval under applicable law or regulations.

        21. Reservation of Stock.

        The Company shall at all times during the term of the Plan reserve and
keep available such number of shares of stock as will be sufficient to satisfy
the requirements of the Plan and shall pay all fees and expenses necessarily
incurred by the Company in connection therewith.

        22. Notices.

        Any communication or notice required or permitted to be given under the
Plan shall be in writing, and mailed by registered or certified mail or
delivered by hand, if to the Company, to its principal place of business,
attention: President, and, if to an optionee, to the address as appearing on the
records of the Company.

Enrollment Date shall be eligible to participate in the Plan.

        (b) Any provisions of the Plan to the contrary notwithstanding, no
Employee shall be granted an option under the Plan (i) to the extent that,
immediately after the grant, such Employee (or any other person whose stock
would be attributed to such Employee pursuant to Section 404(d) of the Code)
would own capital stock of the Company and/or hold outstanding options to
purchase such stock possessing five percent (5%) or more of the total combined

     4. Offering Periods. The Plan shall be implemented by consecutive Offering
Periods with a new Offering Period commencing on the first Trading Day of each
of the three month periods beginning February 7, May 1, August 1 and November 1
of each year or on such other date as the Board shall determine, and continuing
thereafter until terminated in accordance with Section 20 hereof. The first
Offering Period under the Plan shall commence on such date as is determined by
the Board and end on the last Trading Day on or before the end of the calender
quarter which includes such effective date. The Board shall have the power to
change the duration of Offering Periods (including the commencement dates
thereof) with respect to future offerings without stockholder approval if such
change is announced at least five (5) days prior to the scheduled beginning of
the first Offering Period to be affected thereafter.

     5. Participation.

        (a) An eligible Employee may become a participant in the Plan by
completing a subscription agreement authorizing payroll deductions in the form
prescribed for such purpose by the Company and filing it with the Company's
payroll office at least seven (7) days prior to the applicable Enrollment Date.

        (b) Payroll deductions for a participant shall commence on the first
payroll following the Enrollment Date and shall end on the last payroll in the
Offering Period to which such authorization is applicable, unless sooner
terminated by the participant as provided in Section 10 hereof.

     6. Payroll Deductions.

        (a) At the time a participant files his or her subscription agreement,
he or she shall elect to have payroll deductions made on each pay day during the
Offering Period in an amount not exceeding 10% of the Participant's
Compensation.


                                       3
<PAGE>

        (b) All payroll deductions made for a participant shall be credited to
his or her account under the Plan and shall be withheld in whole percentages
only. A participant may not make any additional payments into such account.

        (c) A participant may discontinue his or her participation in the Plan
as provided in Section 10 hereof, or may decrease the rate of his or her payroll
deductions during the Offering Period by completing or filing with the Company a
new subscription agreement authorizing a change in payroll deduction rate. The
Board may, in its discretion, limit the number of participation rate changes
during any Offering Period. The change in rate shall be effective with the first
full payroll period following ten (10) business days after the Company's receipt
of the new subscription agreement unless the Company elects to process a given
change in participation more quickly. A participant's subscription agreement
shall remain in effect for successive Offering Periods unless terminated as
provided in Section 10 hereof.

        (d) Notwithstanding the foregoing, to the extent necessary to comply
with Section 423(b)(8) of the Code and Section 3(b) hereof, a participant's
payroll deductions may be decreased to zero percent (0%) at any time during an
Offering Period. Payroll deductions shall recommence at the rate provided in
such participant's subscription agreement at the beginning of the first Offering
Period which is scheduled to end in the following calendar year, unless
terminated by the participant as provided in Section 10 hereof.

        (e) At the time the option is exercised, in whole or in part, or at the
time some or all of the Company's Common Stock issued under the Plan is disposed
of, the participant must make adequate provision for the Company's federal,
state or other tax withholding obligations, if any, which arise upon the
exercise of the option or the disposition of the Common Stock. At any time, the
Company may, but shall not be obligated to, withhold from the participant's
compensation the amount necessary for the Company to meet applicable withholding
obligations, including any withholding required to make available to the Company
any tax deductions or benefits attributable to sale or early disposition of
Common Stock by the Employee.

     7. Grant of Option. On the Enrollment Date of each Offering Period, each
eligible Employee participating in such Offering Period shall be granted an
option to purchase on the Exercise Date of such Offering Period (at the
applicable Purchase Price) up to a number of shares of the Company's Common
Stock determined by dividing such Employee's payroll deductions accumulated
prior to such Exercise Date and retained in the Participant's account as of the
Exercise Date by the applicable Purchase Price; provided that in no event shall
an Employee be permitted to purchase more than 3,000 shares each year or during
each Offering Period more than 750 shares (subject to any adjustment pursuant to
Section 19), and provided further that such purchase shall be subject to the
limitations set forth in Sections 3(b) and 12 hereof. Exercise of the option
shall occur as provided in Section 8 hereof, unless the participant has
withdrawn pursuant to Section 10 hereof. The Option shall expire on the last day
of the Offering Period.

                                       4
<PAGE>

     8. Exercise of Option. Unless a participant withdraws from the Plan as
provided in Section 10 hereof, his or her option for the purchase of shares
shall be exercised automatically on the Exercise Date, and the maximum number of
full shares subject to option shall be purchased for such participant at the
applicable Purchase Price with the accumulated payroll deductions in his or her
account. No fractional shares shall be purchased; any payroll deductions
accumulated in a participant's account which are not sufficient to purchase a
full share shall be retained in the participant's account for the subsequent
Offering Period, subject to earlier withdrawal by the participant as provided in
Section 10 hereof. Any other monies left over in a participant's account after
the Exercise Date shall be returned to the participant. During a participant's
lifetime, a participant's option to purchase shares hereunder is exercisable
only by him or her.

     9. Delivery. As promptly as practicable after each Exercise Date on which a
purchase of shares occurs, the Company shall arrange the delivery to each
participant, as appropriate, the shares purchased upon exercise of his or her
option.

     10. Withdrawal.

         (a) A participant may withdraw all but not less than all the payroll
deductions credited to his or her account and not yet used to exercise his or
her option under the Plan at any time by giving written notice to the Company at
least seven days before the relevant Exercise Date. All of the participant's
payroll deductions credited to his or her account shall be paid to such
participant promptly after receipt of notice of withdrawal and such
participant's option for the Offering Period shall be automatically terminated,
and no further payroll deductions for the purchase of shares shall be made for
such Offering Period. If a participant withdraws from an Offering Period,
payroll deductions shall not resume at the beginning of the succeeding Offering
Period unless the participant delivers to the Company a new subscription
agreement.

         (b) A participant's withdrawal from an Offering Period shall not have
any effect upon his or her eligibility to participate in any similar plan which
may hereafter be adopted by the Company or in succeeding Offering Periods which
commence after the termination of the Offering Period from which the participant
withdraws.

     11. Termination of Employment. Upon a participant's ceasing to be an
Employee for any reason, he or she shall be deemed to have elected to withdraw
from the Plan and the payroll deductions credited to such participant's account
during the Offering Period, but not yet used to exercise the option shall be
returned to such participant or, in the case of his or her death, to the person
or persons entitled thereto under Section 15 hereof, and such participant's
option shall be automatically terminated. The preceding sentence
notwithstanding, a participant who receives payment in lieu of notice of
termination of employment shall be treated as continuing to be an Employee for
the participant's customary number of hours per week of employment during the
period in which the participant is subject to such payment in lieu of notice.

     12. Interest. No interest shall accrue on the payroll deductions of a
participant in the Plan.

     13. Stock.

         (a) Subject to adjustment upon changes in capitalization of the Company
as provided in Section 19 hereof, the maximum number of shares of the Company's
Common Stock which shall be made available for sale under the Plan shall be four
hundred thousand (400,000) shares If, on a given Exercise Date, the number of
shares with respect to which options are to be exercised exceeds the number of
shares then available under the Plan, the Company shall make a pro rata
allocation of the shares remaining available for purchase in as uniform a manner
as shall be practicable and as it shall determine to be equitable.

         (b) The participant shall have no interest or voting right in shares
covered by his option until such option has been exercised.

         (c) Shares to be delivered to a participant under the Plan shall be
registered in the name of the participant or in the name of the participant and
his or her spouse.

     14. Administration. The Plan shall be administered by the Board or a
committee of members of the Board appointed by the Board. The Board or its
committee shall have full and exclusive discretionary authority to construe,
interpret and apply the terms of the Plan, to determine eligibility and to
adjudicate all disputed claims filed under the Plan. Every finding, decision and
determination made by the Board or its committee shall, to the full extent
permitted by law, be final and binding upon all parties.

     15. Designation of Beneficiary.

         (a) A participant may file a written designation of a beneficiary who
is to receive any shares and cash, if any, from the participant's account under
the Plan in the event of such participant's death subsequent to an Exercise Date
on which the option is exercised but prior to delivery to such participant of
such shares and cash. In addition, a participant may file a written designation
of a beneficiary who is to receive any cash from the participant's account under
the Plan in the event of such participant's death prior to exercise of the
option. If a participant is married and the designated beneficiary is not the
spouse, spousal consent shall be required for such designation to be effective.

         (b) Such designation of beneficiary may be changed by the participant
at any time by written notice. In the event of the death of a participant and in
the absence of a beneficiary validly designated under the Plan who is living at
the time of such participant's death, the Company shall deliver such shares
and/or cash to the executor or administrator of the estate of the participant,
or if no such executor or administrator has been appointed (to the knowledge of
the Company), the Company, in its discretion, may deliver such shares and/or
cash to the spouse or to any one or more dependents or relatives of the
participants, or if no spouse,

                                       6
<PAGE>

dependent or relative is known to the Company, then to such other person as the
Company may designate.

     16. Transferability. Neither payroll deductions credited to a participant's
account nor any rights with regard to the exercise of an option or to receive
shares under the Plan may be assigned, transferred, pledged or otherwise
disposed of in any way (other than by will, the laws of descent and distribution
or as provided in Section 15 hereof) by the participant. Any such attempt at
assignment, transfer, pledge or other disposition shall be without effect,
except that the Company may treat such act as an election to withdraw funds from
an Offering Period in accordance with Section 10 hereof.

     17. Use of Funds. All payroll deductions received or held by the Company
under the Plan may be used by the Company for any corporate purpose, and the
Company shall not be obligated to segregate such payroll deductions.

     18. Reports. Individual accounts shall be maintained for each participant
in the Plan. Statements of account shall be given to participating Employees at
least annually, which statements shall set forth the amounts of payroll
deductions, the Purchase Price, the number of shares purchased and the remaining
cash balance, if any.

     19. Adjustments Upon Changes in Capitalization, Dissolution, Liquidation,
Merger or Asset Sale.

         (a) Changes in Capitalization. Subject to any required action by the
stockholders of the Company, the Reserves, the maximum number of shares each
participant may purchase per Offering Period (pursuant to Section 7), as well as
the price per share and the number of shares of Common Stock covered by each
option under the Plan which has not yet been exercised shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Common
Stock resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Common Stock, or any other increase or
decrease in the number of shares of Common Stock effected without receipt of
consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration". Such adjustment shall be made by the Board,
whose determination in that respect shall be final, binding and conclusive.
Except as expressly provided herein, no issuance by the Company of shares of
stock of any class, or securities convertible into shares of stock of any class,
shall affect, and no adjustment by reason thereof shall be made with respect to,
the number or price of shares of Common Stock subject to an option.

         (b) Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, the Offering Period then in progress
shall be shortened by setting a New Exercise Date (the "New Exercise Date"), and
shall terminate immediately prior to the consummation of such proposed
dissolution or liquidation, unless provided otherwise by the

                                       7
<PAGE>

Board. The New Exercise Date shall be before the date of the Company's proposed
dissolution or liquidation. The Board shall notify each participant in writing,
at least ten (10) business days prior to the New Exercise Date, that the
Exercise Date for the participant's option has been changed to the New Exercise
Date and that the participant's option shall be exercised automatically on the
New Exercise Date, unless prior to such date the participant has withdrawn from
the Offering Period as provided in Section 10 hereof.

         (c) Merger or Asset Sale. In the event of a proposed sale of all or
substantially all of the assets of the Company, or the merger of the Company
with or into another corporation, each outstanding option shall be assumed or an
equivalent option substituted by the successor corporation or a Parent or
Subsidiary of the successor corporation. In the event that the successor
corporation refuses to assume or substitute for the option, the Offering Period
then in progress shall be shortened by setting a new Exercise Date (the "New
Exercise Date"). The New Exercise Date shall be before the date of the Company's
proposed sale or merger. The Board shall notify each participant in writing, at
least ten (10) business days prior to the New Exercise Date, that the Exercise
Date for the participant's option has been changed to the New Exercise Date and
that the participant's option shall be exercised automatically on the New
Exercise Date, unless prior to such date the participant has withdrawn from the
Offering Period as provided in Section 10 hereof.

     20. Amendment or Termination.

         (a) The Board of Directors of the Company may at any time for any
reason terminate or amend the Plan. Except as provided in Section 19 hereof, no
such termination can affect options previously granted, provided that an
Offering Period may be terminated by the Board of Directors or any Exercise Date
if the Board determines that the termination of the Offering Period or the Plan
is in the best interests of the Company and its stockholders. Except as provided
in Section 19 and Section 20 hereof, no amendment may make any change in any
option theretofore granted which adversely affects the rights of any
participant. To the extent necessary to comply with Section 423 of the Code (or
any other applicable law, regulation or stock exchange rule), the Company shall
obtain shareholder approval in such a manner and to such a degree as required.

         (b) Without stockholder consent and without regard to whether any
participant rights may be considered to have been "adversely affected," the
Board (or its committee) shall be entitled to change the Offering Periods, limit
the frequency and/or number of changes in the amount withheld during an Offering
Period, establish the exchange ratio applicable to amounts withheld in a
currency other than U.S. dollars, permit payroll withholding in excess of the
amount designated by a participant in order to adjust for delays or mistakes in
the Company's processing of properly completed withholding elections, establish
reasonable waiting and adjustment periods and/or accounting and crediting
procedures to ensure that amounts applied toward the purchase of Common Stock
for each participant properly correspond with amounts withheld from the
participant's Compensation, and establish such other limitations or procedures

                                       8
<PAGE>

as the Board (or its committee) determines in its sole discretion advisable
which are consistent with the Plan.

         (c) In the event the Board determinate that the ongoing operation of
the Plan may result in unfavorable financial accounting consequences, the Board
may, in its discretion and, to the extent necessary or desirable, modify or
amend the Plan to reduce or eliminate such accounting consequence including, but
not limited to:

             (1) altering the Purchase Price for any Offering Period including
an Offering Period underway at the time of the change in Purchase Price;

             (2) shortening any Offering Period so that Offering Period ends on
a new Exercise Date, including an Offering Period underway at the time of the
Board action; and

             (3) allocating shares.

     Such modifications or amendments shall not require stockholder approval or
the consent of any Plan participant.

     21. Notices. All notices or other communications by a participant to the
Company under or in connection with the Plan shall be deemed to have been duly
given when received in the form specified by the Company at the location, or by
the person, designated by the Company for the receipt thereof.

     22. Conditions Upon Issuance of Shares. Shares shall not be issued with
respect to an option unless the exercise of such option and the issuance and
delivery of such shares pursuant thereto shall comply with all applicable
provisions of law, domestic or foreign, including, without limitation, the
Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as
amended, the rules and regulations promulgated thereunder, and the requirements
of any stock exchange upon which the shares may then be listed, and shall be
further subject to the approval of counsel for the Company with respect to such
compliance.

     As a condition to the exercise of an option, the Company may require the
person exercising such option to represent and warrant at the time of any such
exercise that the shares are being purchased only for investment and without any
present intention to sell or distribute such shares if, in the opinion of
counsel for the Company, such a representation is required by any of the
aforementioned applicable provisions of law.

     23. Term of Plan. The Plan shall become effective upon the earlier to occur
of its adoption by the Board of Directors or its approval by the stockholders of
the Company. It shall continue in effect for a term of ten (10) years unless
sooner terminated under Section 20 hereof.


                                       9


                           MAKER COMMUNICATIONS, INC.
                  1999 NON-EMPLOYEE DIRECTOR STOCK OPTION PLAN

     1. Purpose of the Plan.

     The purpose of this 1999 Non-Employee Director Stock Option Plan (the
"Plan") is to promote the interests of Maker Communications, Inc. (the
"Company") by providing an inducement to attract and retain the services of
qualified persons who are not employees or officers of the Company to serve as
members of its Board of Directors.

     2. Shares Subject to the Plan.

     The initial maximum number of shares of common stock, par value $.01 per
share, of the Company ("Common Stock") available for stock options granted under
the Plan through the end of the Company's fiscal year ending December 31, 1999
shall be 125,000 shares of Common Stock. In addition, effective January 1, 2000
and each January 1 thereafter during the term of this Plan, the number of shares
of Common Stock available for grants of stock options and stock awards made
after such January 1 under this Plan shall be increased automatically to an
amount equal to (i) 125,000 shares or (ii) a lesser amount determined by the
Board of Directors. The Board of Directors shall initially reserve for issuance
under this Plan 125,000 shares of Common Stock. Effective January 1, 2000 and
effective on each succeeding January 1 thereafter during the term of this Plan,
the Board of Directors shall reserve for issuance under this Plan such number of
shares of Common Stock as is equal to the sum of (i) the number of shares of
Common Stock issuable upon the exercise of options then outstanding under the
Plan; and (ii) the number of shares of Common Stock resulting from the
calculation set forth in the second sentence of this paragraph. The number of
shares set forth herein shall be subject to adjustment in accordance with
Section 9 hereof.

     3. Administration.

     This Plan shall be administered by the Board of Directors (the "Board").
The Board shall, subject to the provisions of this Plan, have the power to
construe this Plan, to determine all questions hereunder, and to adopt and amend
such rules and regulations for the administration of this Plan as it may deem
desirable. No member of the Board shall be liable for any action or
determination made in good faith with respect to this Plan or any option granted
under it.

     4. Eligibility; Grant of Option.

     Existing Director Options. Each of Roger Evans, Robi Soni and Louis
Tomasetta, who are the current non-employee directors of the Company who are not
otherwise employees of the Company, shall be granted initially an option to
acquire 20,000 Shares under this Plan (the "Existing Director Options"). The
date of grant for such options granted to the current

<PAGE>

non-employee directors named above shall be January 21, 1999, the date of
adoption of this Plan by the Board.

     New Director Options. Subject to the availability of shares of Common Stock
under this Plan, each person who is first elected as a member of the Board after
the adoption of this Plan and during the term of this Plan and who is not an
employee or officer of the Company on the date of such election shall be granted
on such date an option to purchase 20,000 shares of Common Stock (the "New
Director Options").

     Subsequent Options. In addition to the New Director Options and the
Existing Director Options, each non-employee director of the Company granted
either New Director Options or Existing Director Options pursuant to this Plan
will automatically be granted an option to purchase 15,000 shares (a "Subsequent
Option") on the date two days after the announcement of the Company's fiscal
year-end earnings of each year, if on such date he or she will have served on
the Board of Directors for at least the preceding six months.

     The Existing Director Options, the New Director Options and the Subsequent
Director Options (collectively, the "Options") shall be non-qualified options
not intended to meet the requirements of Section 422 of the Internal Revenue
Code of 1986, as amended (the "Code").

5. Option Agreement.

     Each Option granted under this Plan shall be evidenced by an option
agreement (the "Agreement") duly executed on behalf of the Company and by the
director to whom such Option is granted, which Agreement shall (i) comply with
and be subject to the terms and conditions of this Plan and (ii) provide that
the optionee agrees to continue to serve as a director of the Company during the
term for which he was elected.

     6. Option Exercise Price.

     Existing Director Options. The option exercise price for the Existing
Director Options granted this date shall be $4.40.

     New Director Options and Subsequent Options. Subject to the provisions of
Section 9 hereof, the option exercise price for New Director Options and
Subsequent Options granted under this Plan shall be the fair market value of the
shares of Common Stock covered by the option on the date of grant of the option.
If such shares are then listed on any national securities exchange, the fair
market value shall be the mean between the high and low sales prices, if any, on
such exchange on the date of the grant of the option or, if none, shall be
determined by taking a weighted average of the means between the highest and
lowest sales


                                       2
<PAGE>

prices on the nearest date before and the nearest date after the date of grant.
If the shares are not then listed on any such exchange, the fair market value of
such shares shall be the mean between the high and low sales prices, if any, as
reported in the National Association of Securities Dealers Automated Quotation
System National Market System ("NASDAQ/NMS") for the date of the grant of the
option, or, if none, shall be determined by taking a weighted average of the
means between the highest and lowest sales on the nearest date before and the
nearest date after the date of grant in accordance with Treasury Regulations
Section 25.2512-2. If the shares are not then either listed on any such exchange
or quoted in NASDAQ/NMS, the fair market value shall be the mean between the
average of the "Bid" and the average of the "Ask" prices, if any, as reported in
the National Daily Quotation Service for the date of the grant of the option,
or, if none, shall be determined by taking a weighted average of the means
between the highest and lowest sales prices on the nearest date before and the
nearest date after the date of grant in accordance with Treasury Regulations
Section 25.2512-2. If the fair market value cannot be determined under the
preceding three sentences, it shall be determined in good faith by the Board.

     7. Vesting of Shares and Transferability of Options.

        (a) Vesting. Options granted under the Plan shall not be exercisable
until they become vested. Options granted under the Plan shall be vested by the
optionee and thus become exercisable, in accordance with the following schedules
provided that the optionee has continuously served as a member of the Board
through such vesting date:

     Existing Director Options: Existing Director Options granted under the Plan
shall be exercisable in full immediately upon grant.

     New Director Options and Subsequent Options: Will vest as determined by the
Board.

     Change of Control: In the event the Company undergoes a change of control
all of the Options granted pursuant to this Plan shall immediately vest and
become fully exercisable upon the change of control. For purposes of the Plan, a
"Change of Control" shall be deemed to have occurred if any of the following
conditions have occurred: (1) the merger or consolidation of the Company with
another entity where the Company is not the surviving entity and where after the
merger or consolidation (i) its stockholders prior to the merger or
consolidation hold less than 50% of the voting stock of the surviving entity and
(ii) its Directors prior to the merger or consolidation are less than a majority
of the Board of the surviving entity; (2) the sale of all or substantially all
of the Company's assets to a third party and subsequent to the transaction (i)
its stockholders hold less than 50% of the stock of said third party and (ii)
its Directors are less than a majority of the Board of said third party; (3) a
transaction or series of related transactions,


                                       3
<PAGE>

including a merger of the Company with another entity where the Company is the
surviving entity, whereby (i) 50% or more of the voting stock of the Company
after the transaction(s) is owned actually or beneficially by parties who held
less than thirty percent (30%) of the voting stock, actually or beneficially,
prior to the transaction(s) and (ii) its Board of Directors after the
transaction(s) or within 60 days thereof, is comprised of less than a majority
of the Directors serving prior to the transaction(s); or (4) the Continuing
Directors shall not constitute a majority of the Board of Directors of the
Company. The term "Continuing Directors" shall mean a member of the Board of
Directors of the Company who either was a member of the Board of Directors of
the Company on the date this Plan was adopted by the Board of Directors or who
subsequently became a director of the Company and whose initial appointment,
initial election or initial nomination for election by the Company's
shareholders subsequent to such date was approved by a vote of a majority of the
Continuing Directors then on the Board of Directors of the Company.

         (b) Exercise. To the extent that the right to exercise an Option has
accrued and is in effect, the Option may be exercised in full at one time or in
part from time to time by giving written notice, signed by the person or persons
exercising the Option, to the Company, stating the number of shares of Common
Stock with respect to which the Option is being exercised, accompanied by
payment in full for such shares, which payment may be in cash or in whole or in
part in shares of Common Stock already owned for a period of at least six (6)
months by the person or persons exercising the Option, valued at fair market
value, as determined under Section 6 hereof, on the date of exercise; provided,
however, that there shall be no such exercise at any one time as to fewer than
two hundred fifty (250) shares or all of the remaining shares then purchasable
by the person or persons exercising the Option, if fewer than two hundred fifty
(250) shares. Upon such exercise, delivery of a certificate for paid-up
non-assessable shares shall be made at the principal office of the Company to
the person or persons exercising the Option at such time, during ordinary
business hours, not more than thirty (30) days from the date of receipt of the
notice by the Company, as shall be designated in such notice, or at such time,
place and manner as may be agreed upon by the Company and the person or persons
exercising the Option.

         (d) Legend on Certificates. The certificates representing such shares
shall carry such appropriate legend, and such written instructions shall be
given to the Company's transfer agent, as may be deemed necessary or advisable
by counsel to the Company in order to comply with the requirements of the
Securities Act of 1933, as amended, or any state securities laws.

         (e) Transferability. Any Option granted pursuant to this Plan shall not
be assignable or transferable other than by will or the laws of descent and
distribution, except that an optionee may transfer Options granted under this
Plan to the optionee's spouse or children or to a trust for the benefit of the
optionee or the optionee's spouse or children.


                                       4

<PAGE>

     8.  Term of Options.

         (a) Each Option shall expire no more than ten (10) years from the date
of the granting thereof, but shall be subject to earlier termination as herein
provided.

         (b) Except as otherwise provided in this Section 8, in the event that
an optionee ceases to be a director of the Company, the Option granted to such
optionee may be exercised by him, but only to the extent that under Section 6
hereof the right to exercise the Option has accrued and is in effect. Such
Option may be exercised at any time prior to the last day of the first month
after the date such optionee ceases to be a director of the Company, at which
time the Option shall terminate, or prior to the date on which the Option
expires by its terms, whichever is earlier.

         (c) If the optionee ceases to be a director of the Company because the
optionee has become permanently disabled (within the meaning of Section 22(e)(3)
of the Code), the Option granted to such optionee may be exercised by the
optionee, to the extent the optionee was entitled to do so on the date such
optionee ceases to be a director. Such Option may be exercised at any time
within six months after the date the optionee ceases to be a director, at which
time the Option shall terminate, or prior to the date on which the Option
otherwise expires by its terms, whichever is earlier.

         (d) In the event of the death of an optionee, the Option granted to
such optionee may be exercised, to the extent the optionee was entitled to do so
on the date of such optionee's death, by the estate of such optionee or by any
person or persons who acquired the right to exercise such Option by bequest or
inheritance or otherwise by reason of the death of such optionee. Such Option
may be exercised at any time within one (1) year after the date of death of such
optionee, at which time the Option shall terminate, or prior to the date on
which the Option otherwise expires by its terms, whichever is earlier.


     9. Adjustments.

     Subject to the right to acceleration upon a change of control, as set forth
in Section 7(a) hereof, upon the occurrence of any of the following events, an
optionee's rights with respect to Options granted to him or her hereunder shall
be adjusted as hereinafter provided, unless otherwise specifically provided in
the written agreement between the optionee and the Company relating to such
Option:

         (a) Stock Dividends and Stock Splits. If, the shares of Common Stock
shall be subdivided or combined into a greater or smaller number of shares or if
the Company shall issue any shares of Common Stock as a stock dividend on its
outstanding Common Stock, the number


                                       5
<PAGE>

of shares of Common Stock deliverable upon the exercise of Options shall be
appropriately increased or decreased proportionately, and appropriate
adjustments shall be made in the purchase price per share to reflect such
subdivision, combination or stock dividend.

         (b) Recapitalization or Reorganization. In the event of a
recapitalization or reorganization of the Company pursuant to which securities
of the Company or of another corporation are issued with respect to the
outstanding shares of Common Stock, an optionee upon exercising an Option shall
be entitled to receive for the purchase price paid upon such exercise the
securities he would have received if he had exercised his Option prior to such
recapitalization or reorganization.

         (c) Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, each Option will terminate
immediately prior to the consummation of such proposed action or at such other
time and subject to such other conditions as shall be determined by the
Committee.

         (d) Issuances of Securities. Except as expressly provided herein, no
issuance by the Company of shares of stock of any class, or securities
convertible into shares of stock of any class, shall affect, and no adjustment
by reason thereof shall be made with respect to, the number or price of shares
subject to Options. No adjustments shall be made for dividends paid in cash or
in property other than securities of the Company.

         (e) Fractional Shares. No fractional shares shall be issued under this
Plan and the optionee shall receive from the Company cash in lieu of such
fractional shares.

         (f) Adjustments. Upon the happening of any of the events described in
subparagraphs (a) or (b) above, the class and aggregate number of shares set
forth in Section 2 hereof that are subject to Options which previously have been
or subsequently may be granted under this Plan shall also be appropriately
adjusted to reflect the events described in such subparagraphs. The Board shall
determine the specific adjustments to be made under this paragraph 9 and,
subject to Section 3, its determination shall be conclusive.

     10. Restrictions on Issue of Shares.

     Notwithstanding the provisions of Section 7 hereof, the Company may delay
the issuance of shares of Common Stock covered by the exercise of any Option and
the delivery of a certificate for such shares until one of the following
conditions shall be satisfied:


                                       6

<PAGE>

         (i) the shares with respect to which an Option has been exercised are
at the time of the issue of such shares effectively registered under applicable
Federal and state securities acts now in force or hereafter amended; or

         (ii) counsel for the Company shall have given an opinion, which opinion
shall not be unreasonably conditioned or withheld, that such shares are exempt
from registration under applicable Federal and state securities acts now in
force or hereafter amended.

     It is intended that all exercises of Options shall be effective.
Accordingly, the Company shall use its best efforts to bring about compliance
with the above conditions within a reasonable time, except that the Company
shall be under no obligation to cause a registration statement or a
post-effective amendment to any registration statement to be prepared at its
expense solely for the purpose of covering the issue of shares in respect of
which any Option may be exercised, except as otherwise agreed to by the Company
in writing.

         11. Rights of Holder on Purchase for Investment; Subsequent
Registration.

     Unless the shares of Common Stock to be issued upon exercise of an Option
granted under this Plan have been effectively registered under the Securities
Act of 1933 as now in force or hereafter amended, the Company shall be under no
obligation to issue any shares covered by any Option unless the person who
exercises such Option, in whole or in part, shall give a written representation
and undertaking to the Company which is satisfactory in form and scope to
counsel to the Company and upon which, in the opinion of such counsel, the
Company may reasonably rely, that he is acquiring the shares issued to him
pursuant to such exercise of the Option for his own account as an investment and
not with a view to, or for sale in connection with, the distribution of any such
shares, and that he will make no transfer of the same except in compliance with
any rules and regulations in force at the time of such transfer under the
Securities Act of 1933, as amended, or any other applicable law, and that if
shares are issued without such registration a legend to this effect may be
endorsed upon the securities so issued. In the event that the Company shall,

                            INDEMNIFICATION AGREEMENT



                                THIS INDEMNIFICATION AGREEMENT (this
"Agreement") is entered into as of this ___ day of _________, 199__, by and
among Maker Communications, Inc., a Delaware corporation (the "Company"), and
the indemnitee listed on the signature page hereto (the "Indemnitee").

                                    RECITALS

           A. The Company and Indemnitee recognize the continued difficulty in
obtaining liability insurance for its directors, officers, employees,
shareholders, controlling persons, agents and fiduciaries, the significant
increases in the cost of such insurance and the general reductions in the
coverage of such insurance.

           B. The Company and Indemnitee further recognize the substantial
increase in corporate litigation in general, subjecting directors, officers,
employees, controlling persons, shareholders, agents and fiduciaries to
expensive litigation risks at the same time as the availability and coverage of
liability insurance has been severely limited.

           C. Indemnitee does not regard the current protection available as
adequate under the present circumstances, and Indemnitee and other directors,
officers, employees, shareholders, controlling persons, agents and fiduciaries
of the Company may not be willing to serve in such capacities without additional
protection.

           D. The Company (i) desires to attract and retain the involvement of
highly qualified individual and entities, such as Indemnitee, to serve the
Company and, in part, in order to induce the Indemnitee to be involved with the
Company and (ii) wishes to provide for the indemnification and advancing of
expenses to the Indemnitee to the maximum extent permitted by law.

           E. In view of the considerations set forth above, the Company desires
that the Indemnitee be indemnified by the Company as set forth herein.

                     NOW, THEREFORE, the Company and the Indemnitee hereby
agrees as follows:


                     1.        Indemnification.

                                a. Indemnification of Expenses. The Company
shall indemnify and hold harmless Indemnitee (including his partners,
affiliates, employees, agents and spouse) and each person who controls any of
them or who may be liable within the meaning of Section 15 of the Securities Act
of 1933, as amended (the "Securities Act"), or Section 20 of the Securities
Exchange Act of 1934, as amended (the "Exchange Act"), to the fullest extent
permitted by law if Indemnitee


<PAGE>



was or is or becomes a party to or witness or other participant in, or is
threatened to be made a party to or witness or other participant in, any
threatened, pending or completed action, suit, proceeding or alternative dispute
resolution mechanism, or any hearing, inquiry or investigation that Indemnitee
believes might lead to the institution of any such action, suit, proceeding or
alternative dispute resolution mechanism, whether civil, criminal,
administrative, investigative or other (hereinafter a "Claim") by reason of (or
arising in part or in whole out of) any event or occurrence related to the fact
that Indemnitee is or was or may be deemed a director, officer, employee,
controlling person, agent or fiduciary of the Company, or any subsidiary of the
Company, or is or was serving at the request of the Company as a director,
officer, employee, controlling person, agent or fiduciary of another
corporation, partnership, joint venture, trust or other enterprise, or by reason
of any action or inaction on the part of such Indemnitee while serving in such
capacity including, without limitation, any and all losses, claims, damages,
expenses and liabilities, joint or several (including any investigation, legal
and other expenses incurred in connection with, and any amount paid in
settlement of, any action, suit, proceeding or any claim asserted) under the
Securities Act, the Exchange Act or other federal or state statutory law or
regulation, at common law or otherwise or which relate directly or indirectly to
the registration, purchase, sale or ownership of any securities of the Company
or to any fiduciary obligation owed with respect thereto (hereinafter an
"Indemnification Event") against any and all expenses (including attorneys' fees
and all other costs, expenses and obligations incurred in connection with
investigating, defending a witness in or participating in (including on appeal),
or preparing to defend, be a witness in or participate in, any such action,
suit, proceeding, alternative dispute resolution mechanism, hearing, inquiry or
investigation), judgments, fines, penalties and amounts paid in settlement (if
such settlement is approved in advance by the Company, which approval shall not
be unreasonably withheld) of such Claim and any federal, state, local or foreign
taxes imposed on Indemnitee as a result of the actual or deemed receipt of any
payments under this Agreement (collectively, hereinafter "Expenses"), including
all interest, assessments and other charges paid or payable in connection with
or in respect of such Expenses. Such payment of Expenses shall be made by the
Company as soon as practicable but in any event no later than ten (10) days
after written demand by the Indemnitee therefor is presented to the Company.

                                b. Reviewing Party. Notwithstanding the
foregoing, (i) the obligations of the Company under Section 1(a) shall be
subject to the condition that the Reviewing Party (as described in Section 10(e)
hereof) shall not have determined (in a written opinion, in any case in which
the Independent Legal Counsel referred to in Section 1(e) hereof is involved)
that Indemnitee would not be permitted to be indemnified under applicable law,
and (ii) and Indemnitee acknowledges and agrees that the obligation of the
Company to make an advance payment of Expenses to Indemnitee pursuant to Section
2(a) (an "Expense Advance") shall be subject to the condition that, if, when and
to the extent that the Reviewing Party determines that Indemnitee would not be
permitted to be so indemnified under applicable law, the Company shall be
entitled to be reimbursed by Indemnitee (who hereby agrees to reimburse the
Company) for all such amounts theretofore paid; provided, however, that if
Indemnitee has commenced or thereafter commences legal proceedings in a court of
competent jurisdiction to secure a determination that Indemnitee should be
indemnified under applicable law, any determination made by the Reviewing Party
that Indemnitee would not be permitted to be indemnified under applicable law
shall not be binding and Indemnitee shall not be required to reimburse the
Company for any Expense Advance until a final


<PAGE>



judicial determination is made with respect thereto (as to which all rights of
appeal therefrom have been exhausted or lapsed). Indemnitee's obligation to
reimburse the Company for any Expense Advance shall be unsecured and no interest
shall be charged thereon. If there has not been a Change in Control (as defined
in Section 10(c) hereof), the Reviewing Party shall be selected by the Board of
Directors, and if there has been such a Change in Control (other than a Change
in Control which has been approved by a majority of the Company's Board of
Directors who were directors immediately prior to such Change in Control), the
Reviewing Party shall be the Independent Legal Counsel referred to in Section
1(e) hereof. If there has been no determination by the Reviewing Party or if the
Reviewing Party determines that Indemnitee substantively would not be permitted
to be indemnified in whole or in part under applicable law, Indemnitee shall
have the right to commence litigation seeking an initial determination by the
court or challenging any such determination by the Reviewing Party or any aspect
thereof, including the legal or factual bases therefor, and the Company hereby
consents to service of process and to appear in any such proceeding. Any
determination by the Reviewing Party otherwise shall be conclusive and binding
on the Company and Indemnitee.

                                c. Contribution. If the indemnification provided
for in Section 1(a) above for any reason is held by a court of competent
jurisdiction to be unavailable to an Indemnitee in respect of any losses,
claims, damages, expenses or liabilities referred to therein, then the Company,
in lieu of indemnifying such Indemnitee thereunder, shall contribute to the
amount paid or payable by Indemnitee as a result of such losses, claims,
damages, expenses or liabilities (i) in such proportion as is appropriate to
reflect the relative benefits received by the Company and the Indemnitee, or
(ii) if the allocation provided by clause (i) above is not permitted by
applicable law, in such proportion as is appropriate to reflect not only the
relative benefits referred to in clause (i) above but also the relative fault of
the Company and the Indemnitee in connection with the action or inaction which
resulted in such losses, claims, damages, expenses or liabilities, as well as
any other relevant equitable considerations. In connection with the registration
of the Company's securities, the relative benefits received by the Company and
the Indemnitee shall be deemed to be in the same respective proportions that the
net proceeds from the offering (before deducting expenses) received by the
Company and the Indemnitee, in each case as set forth in the table on the cover
page of the applicable prospectus, bear to the aggregate public offering price
of the securities so offered. The relative fault of the Company and the
Indemnitee shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the Company
or the Indemnitee and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.

                                The Company and the Indemnitee agree that it
would not be just and equitable if contribution pursuant to this Section 1(c)
were determined by pro rata or per capita allocation or by any other method of
allocation which does not take account of the equitable considerations referred
to in the immediately preceding paragraph. In connection with the registration
of the Company's securities, in no event shall Indemnitee be required to
contribute any amount under this Section 1(c) in excess of the lesser of (i)
that proportion of the total of such losses, claims, damages or liabilities
indemnified against equal to the proportion of the total securities sold under
such registration statement which is being sold by Indemnitee or (ii) the
proceeds received by Indemnitee from its sale


<PAGE>



of securities under such registration statement. No person found guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
found guilty of such fraudulent misrepresentation.

                                d. Survival Regardless of Investigation. The
indemnification and contribution provided for in this Section 1 will remain in
full force and effect regardless of any investigation made by or on behalf of
the Indemnitee or any officer, director, employee, agent or controlling person
of the Indemnitee.

                                e. Change in Control. After the date hereof, the
Company agrees that if there is a Change in Control of the Company (other than a
Change in Control which has been approved by a majority of the Company's Board
of Directors who were directors immediately prior to such Change in Control)
then, with respect to all matters thereafter arising concerning the rights of
Indemnitee to payments of Expenses under this Agreement or any other agreement
or under the Company's Certificate of Incorporations or Bylaws as now or
hereafter in effect, Independent Legal Counsel (as defined in Section 10(d)
hereof) shall be selected by the Indemnitee and approved by the Company (which
approval shall not be unreasonably withheld). Such counsel, among other things,
shall render its written opinion to the Company and Indemnitee as to whether and
to what extent Indemnitee would be permitted to be indemnified under applicable
law. The Company agrees to abide by such opinion and to pay the reasonable fees
of the Independent Legal Counsel referred to above and to fully indemnify such
counsel against any and all expenses (including attorneys' fees), claims,
liabilities and damages arising out of or relating to this Agreement or its
engagement pursuant hereto.

                                f. Mandatory Payment of Expenses.
Notwithstanding any other provision of this Agreement, to the extent that
Indemnitee has been successful on the merits or otherwise, including, without
limitation, the dismissal of an action without prejudice, in the defense of any
action, suit, proceeding, inquiry or investigation referred to in Section 1(a)
hereof or in the defense of any claim, issue or matter therein, Indemnitee shall
be indemnified against all Expenses incurred by Indemnitee in connection
herewith.

                                2. Expenses; Indemnification Procedure.

                                a. Advancement of Expenses. The Company shall
advance all Expenses incurred by Indemnitee. The advances to be made hereunder
shall be paid by the Company to Indemnitee as soon as practicable but in any
event no later than five days after written demand by such Indemnitee therefor
to the Company.

                                b. Notice/Cooperation by Indemnitee. Indemnitee
shall give the Company notice as soon as practicable of any Claim made against
Indemnitee for which indemnification will or could be sought under this
Agreement. Notice to the Company shall be directed to the Chief Executive
Officer of the Company at the address shown on the signature page of this
agreement (or such other address as the Company shall designate in writing to
Indemnitee).



<PAGE>



                                c. No Presumptions; Burden of Proof. For
purposes of this Agreement, the termination of any Claim by judgment, order,
settlement (whether with or without court approval) or conviction, or upon a
plea of nolo contendere, or its equivalent, shall not create a presumption that
Indemnitee did not meet any particular standard of conduct or have any
particular belief or that a court has determined that indemnification is not
permitted by applicable law. In addition, neither the failure of the Reviewing
Party to have made a determination as to whether Indemnitee has met any
particular standard of conduct or had any particular belief, nor an actual
determination by the Reviewing Party that Indemnitee has not met such standard
of conduct or did not have such belief, prior to the commencement of legal
proceedings by Indemnitee to secure a judicial determination that Indemnitee
should be indemnified under applicable law, shall be a defense to Indemnitee's
claim or create a presumption that Indemnitee has not met any particular
standard of conduct or did not have any particular belief. In connection with
any determination by the Reviewing Party or otherwise as to whether Indemnitee
is entitled to be indemnified hereunder, the burden of proof shall be on the
Company to establish that Indemnitee is not so entitled.

                                d. Notice to Insurers. If, at the time of the
receipt by the Company of a notice of a Claim pursuant to Section 2(b) hereof,
the Company has liability insurance in effect which may cover such Claim, the
Company shall give prompt written notice of the commencement of such Claim to
the insurers in accordance with the procedures set forth in each of the
policies. The Company shall thereafter take all necessary or desirable action to
cause such insurers to pay, on behalf of Indemnitee, all amounts payable as a
result of such action, suit, proceeding, inquiry or investigation in accordance
with the terms of such policies.

                                e. Selection of Counsel. In the event the
Company shall be obligated hereunder to pay the Expenses of any Claim, the
Company shall be entitled to assume the defense of such Claim, with counsel
reasonably approved by the applicable Indemnitee, upon the delivery to
Indemnitee of written notice of its election to do so. After delivery of such
notice, approval of such counsel by the Indemnitee and the retention of such
counsel by the Company, the Company will not be liable to Indemnitee under this
Agreement for any fees of counsel subsequently incurred by Indemnitee with
respect to the same Claim; provided that, (i) the Indemnitee shall have the
right to employ Indemnitee's counsel in any such Claim at the Indemnitee's
expense; (ii) the Indemnitee shall have the right to employ his own counsel in
connection with any such proceeding, at the expense of the Company, if such
counsel serves in a review, observer, advice and counseling capacity and does
not otherwise materially control or participate in the defense of such
proceeding; and (iii) if (A) the employment of counsel by the Indemnitee has
been previously authorized by the Company, (B) Indemnitee shall have reasonably
concluded that there is a conflict of interest between the Company and
Indemnitee in the conduct of any such defense, or (C) the Company shall not
continue to retain such counsel to defend such Claim, then the fees and expenses
of the Indemnitee's counsel shall be at the expense of the Company. The Company
shall have the right to conduct such defense as it sees fit in its sole
discretion, including the right to settle any claim against any Indemnitee
without the consent of Indemnitee.

                                3. Additional Indemnification Rights;
Nonexclusivity.

                                a. Scope. The Company hereby agrees to indemnify
Indemnitee to the fullest extent permitted by law, even if such indemnification
is not specifically authorized by the other provisions of this Agreement, the
Company's Certificate of Incorporation, the Company's Bylaws or by statute. In
the event of any change after the date of this Agreement in any applicable law,
statute or rule which expands the right of a Delaware corporation to indemnify a
member of its Board of Directors or an officer, employee, controlling person,
agent or fiduciary, it is the intent of the parties hereto that Indemnitee shall
enjoy by this Agreement the greater benefits afforded by such change. In the
event of any change in any applicable law, statute or rule which narrows the
right of a Delaware corporation to indemnify a member of its Board of Directors
or an officer, employee, agent or fiduciary, such change, to the extent not
otherwise required by such law, statute or rule to be applied to this Agreement,
shall have no effect on this Agreement or the parties' rights and obligations
hereunder except as set forth in Section 8(a) hereof.

                                b. Nonexclusivity. The indemnification provided
by this Agreement shall be in addition to any rights to which Indemnitee may be
entitled under the Company's Certificate of Incorporation, its Bylaws, any
agreement, any vote of shareholders or disinterested directors, the General
Corporation Law of the State of Delaware, or otherwise. The indemnification
provided under this Agreement shall continue as to Indemnitee for any action
Indemnitee took or did not take while serving in an indemnified capacity even
though the Indemnitee may have ceased to serve in such capacity.

                                4. No Duplication of Payments. The Company shall
not be liable under this Agreement to make any payment in connection with any
Claim made against any Indemnitee to the extent Indemnitee has otherwise
actually received payment (under any insurance policy, Certificate of
Incorporation, Bylaws or otherwise) of the amounts otherwise indemnifiable
hereunder.

                                5. Partial Indemnification. If any Indemnitee is
entitled under any provision of this Agreement to indemnification by the Company
for any portion of Expenses incurred in connection with any Claim, but not,
however, for all of the total amount thereof, the Company shall nevertheless
indemnify Indemnitee for the portion of such Expenses to which Indemnitee is
entitled.

                                6. Mutual Acknowledgment. The Company and
Indemnitee acknowledge that in certain instances, Federal law or applicable
public policy may prohibit the Company from indemnifying its directors,
officers, employees, controlling persons, agents or fiduciaries under this
Agreement or otherwise. Each Indemnitee understands and acknowledges that the
Company has undertaken or may be required to undertake with the Securities and
Exchange Commission to submit the question of indemnification to a court in
certain circumstances for a determination of the Company's rights under public
policy to indemnify Indemnitee.

                                7. Liability Insurance. To the extent the
Company maintains liability insurance applicable to directors, officers,
employees, control persons, agents or fiduciaries, each Indemnitee shall be
covered by such policies in such a manner as to provide Indemnitee the same
rights and benefits as are accorded to the most favorably insured of the
Company's directors, if Indemnitee is


<PAGE>



a director, or of the Company's officers, if Indemnitee is not a director of the
Company but is an officer; or of the Company's key employees, controlling
persons, agents or fiduciaries, if Indemnitee is not an officer or director but
is a key employee, agent, control person, or fiduciary.

                                8. Exceptions. Any other provision herein to the
contrary notwithstanding, the Company shall not be obligated pursuant to the
terms of this Agreement:

                                a. Claims Initiated by Indemnitee. To indemnify
or advance expenses to any Indemnitee with respect to Claims initiated or
brought voluntarily by Indemnitee and not by way of defense, except (i) with
respect to actions or proceedings to establish or enforce a right to indemnify
under this Agreement or any other agreement or insurance policy or under the
Company's Certificate of Incorporation or Bylaws now or hereafter in effect
relating to Claims for Indemnifiable Events, (ii) in specific cases if the Board
of Directors has approved the initiation or bringing of such Claim, or (iii) as
otherwise required under section 145 of Delaware General Corporation Law,
regardless of whether Indemnitee ultimately is determined to be entitled to such
indemnification, advance expense payment or insurance recovery, as the case may
be; or

                                b. Claims Under Section 16(b). To indemnify any
Indemnitee for expenses and the payment of profits arising from the purchase and
sale by Indemnitee of securities in violation of Section 16(b) of the Exchange
Act or any similar successor statute; or

                                c. Claims Excluded Under Section 145 of the
Delaware General Corporation Law. To indemnify an Indemnitee if (i) he did not
act in good faith and in a manner reasonably believed to be in or not opposed to
the best interests of the Company, or (ii) with respect to any criminal action
or proceeding, Indemnitee had reasonable cause to believe his conduct was
unlawful, or (iii) Indemnitee shall have been adjudged to be liable to the
Company unless and only to the extent the court in which such action was brought
shall permit indemnification as provided in Section 145(b) of the Delaware
General Corporation Law.

                                9. Period of Limitations. No legal action shall
be brought and no cause of action shall be asserted by or in the right of the
Company against any Indemnitee, any Indemnitee's estate, spouse, heirs,
executors or personal or legal representatives after the expiration of five (5)
years from the date of accrual of such cause of action, and any claim or cause
of action of the Company shall be extinguished and deemed released unless
asserted by the timely filing of a legal action within such five (5) year
period; provided, however, that if any shorter period of limitations is
otherwise applicable to any such cause of action, such shorter period shall
govern.

                     10.       Construction of Certain Phrases.

                                a. For purposes of this Agreement, references to
the "Company" shall include, in addition to the resulting corporation, any
constituent corporation (including any constituent of a constituent) absorbed in
a consolidation or merger which, if its separate existence had continued, would
have had power and authority to indemnify its directors, officers, employees,
agents or fiduciaries, so that if Indemnitee is or was or may be deemed a
director, officer, employee, agent, control person, or fiduciary of such
constituent corporation, or is or was serving at the request


<PAGE>



of such constituent corporation as a director, officer, employee, control
person, agent or fiduciary of another corporation, partnership, joint venture,
employee benefit plan, trust or other enterprise, Indemnitee shall stand in the
same position under the provisions of this Agreement with respect to the
resulting or surviving corporation as each Indemnitee would have with respect to
such constituent corporation if its separate existence had continued.

                                b. For purposes of this Agreement, references to
"other enterprises" shall include employee benefit plans; references to "fines"
shall include any excise taxes assessed on any Indemnitee with respect to an
employee benefit plan; and references to "serving at the request of the Company"
shall include any service as a director, officer, employee, agent or fiduciary
of the Company which imposes duties on, or involves services by, such director,
officer, employee, agent or fiduciary with respect to an employee benefit plan,
its participants or its beneficiaries; and if any Indemnitee acted in good faith
and in a manner Indemnitee reasonably believed to be in the interest of the
participants and beneficiaries of an employee benefit plan, Indemnitee shall be
deemed to have acted in a manner "not opposed to the best interests of the
Company" as referred to in this Agreement.

                                c. For purposes of this Agreement a "Change in
Control" shall be deemed to have occurred if (i) any "person" (as such term is
used in Sections 13(d)(3) and 14(d)(2) of the Exchange Act), other than a
trustee or other fiduciary holding securities under an employee benefit plan of
the Company or a corporation owned directly or indirectly by the shareholders of
the Company in substantially the same proportions as their ownership of stock of
the Company, (A) who is or becomes the beneficial owner, directly or indirectly,
of securities of the Company representing 10% or more of the combined voting
power of the Company's then outstanding Voting Securities, increases his
beneficial ownership of such securities by 5% or more over the percentage so
owned by such person, or (B) becomes the "beneficial owner" (as defined in Rule
13d-3 under said Exchange Act), directly or indirectly, of securities of the
Company representing more than 20% of the total voting power represented by the
Company's then outstanding Voting Securities, (ii) during any period of two
consecutive years, individuals who at the beginning of such period constitute
the Board of Directors of the Company and any new director whose election by the
Board of Directors or nomination for election by the Company's shareholders was
approved by a vote of at least two-thirds (2/3) of the directors then still in
office who either were directors at the beginning of the period or whose
election or nomination for election was previously so approved, cease for any
reason to constitute a majority thereof, or (iii) the shareholders of the
Company approve a merger or consolidation of the Company with any other
corporation other than a merger or consolidation which would result in the
Voting Securities of the Company outstanding immediately prior thereto
continuing to represent (either by remaining outstanding or by being converted
into Voting Securities of the surviving entity) at least 80% of the total voting
power represented by the Voting Securities of the Company or such surviving
entity outstanding immediately after such merger or consolidation, or the
shareholders of the Company approve a plan of complete liquidation of the
Company or an agreement for the sale or disposition by the Company of (in one
transaction or a series of transactions) all or substantially all of the
Company's assets.

                                d. For purposes of this Agreement, "Independent
Legal Counsel" shall mean an attorney or firm of attorneys, selected in
accordance with the provisions of Section 1(e)

hereof, who shall not have otherwise performed services for the Company or any
Indemnitee within the last three (3) years (other than with respect to matters
concerning the right of any Indemnitee under this Agreement, or of other
indemnitees under similar indemnity agreements).

                                e. For purposes of this Agreement, a "Reviewing
Party" shall mean any appropriate person or body consisting of a member or
members of the Company's Board of Directors or any other person or body
appointed by the Board of Directors who is not a party to the particular Claim
for which Indemnitee is seeking indemnification, or Independent Legal Counsel.

                                f. For purposes of this Agreement, "Voting
Securities" shall mean any securities of the Company that vote generally in the
election of directors.

                                11. Counterparts. This Agreement may be executed
in one or more counterparts, each of which shall constitute an original.

                                12. Binding Effect; Successors and Assigns. This
Agreement shall be binding upon and inure to the benefit of and be enforceable
by the parties hereto and their respective successors, assigns, including any
direct or indirect successor by purchase, merger, consolidation or otherwise to
all or substantially all of the business and/or assets of the Company, spouses,
heirs, and personal and legal representatives. The Company shall require and
cause any successor (whether direct or indirect by purchase, merger,
consolidation or otherwise) to all, substantially all, or a substantial part, of
the business and/or assets of the Company, by written agreement in form and
substance satisfactory to Indemnitee, expressly to assume and agree to perform
this Agreement in the same manner and to the same extent that the Company would
be required to perform if no such succession had taken place. This Agreement
shall continue in effect with respect to Claims relating to Indemnifiable Events
regardless of whether any Indemnitee continues to serve as a director, officer,
employee, agent, controlling person, or fiduciary of the Company or of any other
enterprise, including subsidiaries of the Company, at the Company's request.

                                13. Attorneys' Fees. In the event that any
action is instituted by an Indemnitee under this Agreement or under any
liability insurance policies maintained by the Company to enforce or interpret
any of the terms hereof or thereof, any Indemnitee shall be entitled to be paid
all Expenses incurred by Indemnitee with respect to such action, regardless of
whether Indemnitee is ultimately successful in such action, and shall be
entitled to the advancement of Expenses with respect to such action, unless, as
a part of such action, a court of competent jurisdiction over such action
determines that each of the material assertions made by Indemnitee as a basis
for such action was not made in good faith or was frivolous. In the event of an
action instituted by or in the name of the Company under this Agreement to
enforce or interpret any of the terms of this Agreement, the Indemnitee shall be
entitled to be paid all Expenses incurred by Indemnitee in defense of such
action (including costs and expenses incurred with respect to Indemnitee
counterclaims and cross-claims made in such action), and shall be entitled to
the advancement of Expenses with respect to such action, unless, as a part of
such action, a court having jurisdiction over such action determines that each
of Indemnitee's material defenses to such action was made in bad faith or was
frivolous.

                                14. Notice. All notices and other communications
required or permitted hereunder shall be in writing, shall be effective when
given, and shall in any event be deemed to be given (a) five (5) days after

by hand, (c) one business day after the business day of deposit with Federal

Company, at the address of its principal corporate offices (attention:
Secretary) or at such other address as such party may designate by ten (10)
days' advance written notice to the other party hereto.

                                15. Consent to Jurisdiction. The Company and
Indemnitee each hereby irrevocably consent to the jurisdiction and venue of the
courts of the State of Delaware for all purposes in connection with any action
or proceeding which arises out of or relates to this Agreement and agree that
any action instituted under this Agreement shall be commenced, prosecuted and
continued only in the Court of Chancery of the State of Delaware in and for New
Castle County, which shall be the exclusive and only proper forum for
adjudicating such a claim.

                                16. Severability. The provisions of this
Agreement shall be severable in the event that any of the provisions hereof
(including any provision within a single section, paragraph or sentence) are
held by a court of competent jurisdiction to be invalid, void or otherwise
unenforceable, and the remaining provisions shall remain enforceable to the
fullest extent permitted by law. Furthermore, to the fullest extent possible,
the provisions of this Agreement (including, without limitations, each portion
of this Agreement containing any provision held to be invalid, void or otherwise
unenforceable, that is not itself invalid, void or unenforceable) shall be
construed so as to give effect to the intent manifested by the provision held
invalid, illegal or unenforceable.

                                17. Choice of Law. This Agreement shall be
governed by and its provisions construed and enforced in accordance with the
laws of the State of Delaware, as applied to contracts between Delaware
residents, entered into and to be performed entirely within the State of
Delaware, without regard to the conflict of laws principles thereof.

                                18. Subrogation. In the event of payment under
this Agreement, the Company shall be subrogated to the extent of such payment to
all of the rights of recovery of Indemnitee who shall execute all documents
required and shall do all acts that may be necessary to secure such rights and
to enable the Company effectively to bring suit to enforce such rights.

                                19. Amendment and Termination. No amendment,
modification, termination or cancellation of this Agreement shall be effective
unless it is in writing signed by all parties hereto. Notice of same shall be
provided to all parties hereto. No waiver of any of the provisions of this
Agreement shall be deemed or shall constitute a waiver of any other provisions
hereof (whether or not similar) nor shall such waiver constitute a continuing
waiver.

                                20. Integration and Entire Agreement. This
Agreement sets forth the entire understanding between the parties hereto and
supersedes and merges all previous written and oral


<PAGE>



negotiations, commitments, understandings and agreements relating to the subject
matter hereof between the parties hereto.

                                21. No Construction as Employment Agreement.
Nothing contained in this Agreement shall be construed as giving the Indemnitee
any right to be retained in the employ of the Company or any of its
subsidiaries.

                                22. Corporate Authority. The Board of Directors
of the Company and its shareholders have approved the terms of this Agreement.
