                                      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 network traffic
and interconnecting 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 performing translation functions used to interconnect different
networks and protocols. 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. Currently OC-12 is the fastest speed at
which commercial Asynchronous Transfer Mode Segmentation and Reassembly devices
operate. 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
may not 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. We derive revenue from this process only if our
design is selected. 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, they
may not continue to grow and a significant slowdown in these markets may occur.
 

     In addition, a substantial majority of our revenues has been, and is
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 potential customers have substantial
technological capabilities and financial resources which enable them


                                       8
Risk Factors

<PAGE>

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
assure you that the MXT4400 will perform as anticipated and there may 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 has 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, Ascend, Cisco and Fore, accounted for 29%, 16% and
13% of revenues, respectively. No other customer accounted for greater than 10%
of revenues 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 a consolidation. This
consolidation may result in the cancellation of current product orders. This
industry may experience further consolidation in the future which may result in
product duplication and cancellation of current projects, which may 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 assure you 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.


                                       10
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
several domestic patents and have several foreign patent applications on file.
We 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
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 assure you 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 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 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 and the Concurrent Private Placement

     A substantial majority of our capital stock is held by a limited number of
stockholders. After completion of this offering and the concurrent private
placement, our officers and directors and parties affiliated with or related to
such persons or to Maker will own approximately 69% 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 17,536,983 shares of common stock outstanding immediately
after the offering and the concurrent private placement. Of these shares, the
shares sold in the offering will be freely transferable without restriction or
further registration under the Securities Act, except for any shares purchased
by our "affiliates" as defined in Rule 144 under the Securities Act. The
remaining 14,536,983 shares of common stock outstanding will be "restricted
securities" as defined in Rule 144. These shares may be sold in the future
without registration under the Securities Act to the extent permitted by Rule
144 or an exemption under the Securities Act. In addition, additional shares of
common stock subject to outstanding vested stock options could also be sold.
The holders of the shares of common stock issued upon conversion of Class B
Convertible Preferred Stock and Class C Convertible Preferred Stock and Cisco
will also have registration rights allowing them to cause us to register their
shares under the Securities Act.

     In connection with the offering, Maker's executive officers, directors and
stockholders owning, in the aggregate, 13,907,782 shares have agreed that,
without the consent of Lehman Brothers Inc., they will not sell any shares of
common stock for at least 150 days after the date of this prospectus.
Additionally, these stockholders will not sell more than one-third of their
shares of common stock for at least 180 days after the date of this prospectus.
Finally, these stockholders will not sell more than two-thirds of their shares
of common stock for at least 210 days after the date of this prospectus. These
lock-up agreements expire in full 210 days after the date of this prospectus.
In addition, Cisco has agreed that it will not sell any shares of common stock
for at least 180 days after the concurrent private placement. Maker has agreed
not to sell or otherwise dispose of any shares of common stock for a period of
180 days, except as consideration for the acquisition of businesses.

                                USE OF PROCEEDS

   
     We estimate that we will receive net proceeds from this offering of
approximately $26,900,000, or $31,782,500 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 (which will
occur simultaneously with the closing of this offering), 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.

                                    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 and the concurrent
private placement at the assumed initial offering price net of the estimated
underwriting discount, 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 $3,100,000.
    


     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, the new shareholders from the
concurrent private placement 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
31, 1999. At March 31, 1999, there were 2,635,940 shares of common stock
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.

                     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 Maker'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. 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. Approximately 60% of the increase was due to an increase in direct
product costs which is associated with the increase in product revenues. The
remainder of the increase was due to an increase in personnel and related
overhead costs to support Maker'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 Maker 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. Approximately 70% of the
increase was due to an increase in personnel and related costs and the
remainder of the increase was primarily due to an increase in recruiting and
outside consulting 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. Substantially all of the increase reflects
an increase in personnel to support Maker's product marketing activities which
included the introduction of the MXT4400 Traffic Stream Processor in March
1999. 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. Substantially all of the increase
reflects increased personnel and related costs incurred in expanding the human
resource and accounting functions. 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.

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

<PAGE>

     Cost of Revenues. Cost of revenues increased from $329,000 in 1996 to $1.0
million in 1997 to $3.2 million in 1998. Approximately 60% of the increase in
cost of revenues in 1997 and 1998 was due to increases in direct product costs
and the remainder of the increase was due to increases in pre-production costs
and support and documentation costs associated with the increase in revenues.
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. Approximately 70% of the increase in 1997 was due to increases in
personnel and related costs and the remainder was primarily due to increases in
engineering supplies and prototype costs. 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.
Approximately 50% of the increase in 1998 was due to increases in personnel and
related costs and the remainder was primarily due to increases in outside
consulting services and depreciation of computer equipment. 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.
Approximately 80% and 70% of the increases in 1997 and 1998, respectively, were
due to increases in salaries and related costs. The remainder of the increases
in both 1997 and 1998 were due to increased public relation costs and marketing
materials.

     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.
Approximately 60% and 35% of the increases in 1997 and 1998, respectively, were
primarily due to the hiring of additional personnel, including senior level
management. The remainder of the increase was due to increases in costs
associated with supporting the business including increases in legal and
professional fees and human resource activities of approximately 35% and 50% in
1997 and 1998, respectively.

     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
<PAGE>

     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 primarily from increases in accrued expenses of
$404,000 and depreciation and amortization expenses of $132,000, partially
offset by an increase in inventory of $206,000. The increase in accrued
expenses was primarily a result of increased accrued professional fees and the
increase in inventory was sales volume related. 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 at least the
next 12 months. In addition, concurrent with this offering, Maker will sell
500,000 shares of common stock to Cisco at a per share price equal to the
assumed initial offering price net of estimated underwriting discount for
assumed gross proceeds to Maker of $4,650,000. Thereafter, Maker's future
capital requirements will depend on many factors, including the level of
investment Maker makes in new technologies and improvements to existing
technologies, the production levels Maker maintains and the level of monthly
expenses required to launch new products. To the extent that the funds generated
by this offering, together with proceeds from the concurrent private placement,
existing resources and future earnings are insufficient to fund Maker's future
activities, Maker may need to raise additional funds through public or private
financing. Additional funds may not be available or, if available, Maker may not
be able to obtain them on terms favorable to it and its stockholders. In
addition, Maker could seek to raise additional capital if it identified
acquisitions or investments in complementary business, technologies or product
lines.

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 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.
Additionally, Maker has not yet begun to assess the Year 2000 readiness of its
material customers.

     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

<PAGE>

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 Asynchronous
Transfer Mode over SONET (Synchronous Optical Network) and Packet over SONET.
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 an
internetworking function for translating between fixed-sized-packet
Asynchronous Transfer Mode networks and variable-sized-packet 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

                                       27

                                                                        Business

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

     Maker's top five customers in 1998 were Ascend, Cisco, Fore, Lucent and
Nortel. Ascend, Cisco and Fore each 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:

Maker's Solution Architecture


     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 has a
relatively small market share and 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, in which Maker believes there is currently
little competition, Maker expects to compete in the future with several of the
foregoing companies and others. In the Asynchronous Transfer Mode traffic
policing market, a targeted future market for Maker, there are a number of
competitors, including Lucent and PMC-Sierra. In Asynchronous Transfer Mode
markets for programmable integrated circuits, LSI Logic and Motorola currently
offer programmable cell processing capability; Maker believes it competes
effectively at the high-end (integrated circuits which run at rates greater
than OC-3) of this market.

     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 numerous technology and software licenses
which entitle it to use software and technology of other companies. Maker has
one technology license agreement which it believes to be material. This
agreement provides synthesizable core software product and is terminable only
upon breach by one of the parties. 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


                                       33

                                                                        Business
<PAGE>

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 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. Third parties may
assert infringement claims against Maker in the future, which may result in
costly litigation. Maker may not prevail in any such litigation or may not 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.

     In addition, competitors of Maker, many of which have substantially
greater resources than Maker and have made substantial investments in competing
technologies, may have, or may 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. Maker may
also 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 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. See
"Risk Factors--We Need to Protect Our Intellectual Property and Avoid
Infringement of the Intellectual Property of Others."


Backlog

     Maker does not believe that the amount of its backlog is material. This
backlog is subject to continued fluctuations and is not necessarily indicative
of future sales. Customers purchase Maker's products pursuant to short term
purchase orders which may be canceled without charge if notice is given within
an agreed upon period. The Company's design wins are solely an expression of
interest by customers and are not supported by binding contracts of any nature.
Therefore, there can be no assurance that any design win will result in
purchase orders for the Company's products.

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

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) 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.

(2) The grant date valuation is determined by the board of directors and is
    consistent with the value used by Maker for accounting purposes to
    determine if any compensation expense related to option grants is
    reportable.

(3) The options become 20% vested on September 17, 1999. The remainder of the
    options vest evenly on a quarterly basis over the next four years.

(4) The options became 20% vested on March 12, 1999. The remainder of the

(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 has the authority to take the following
actions:

   (a) interpret and apply the 1996 Plan;

   (b) determine the eligibility of an individual to participate in the 1996
   Plan;

     (c) approve 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) determine and allocate 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 one of
the following:

     (a) cash or a check payable to Maker in an amount equal to the exercise
price of the vested options;

     (b) shares of Maker's common stock owned by the optionholder having a fair
market value equal in amount to the exercise price of the options being
exercised;


                                       39

                                                                      Management
<PAGE>

     (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; or

     (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 option holder or cancellation of shares covered by the option may be made
only with the consent of the Board if the payment or cancellation 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 the shares for which the option has been exercised have been
registered or qualified under the applicable federal or state securities laws,
or counsel for Maker has opined that the shares are exempt from the
registration requirements of applicable federal or state securities laws.

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

     The term of any option granted under the Plan is limited to ten years.
Upon the termination of an optionholder's employment with Maker, his or her
options shall terminate between 30 days and 12 months 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 125,000 shares, or 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 that he or she first becomes a non-employee director, unless
immediately prior to becoming a non-employee director, he or she was an
employee director of Maker. 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 at
that time 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
shall 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 shall
become immediately exercisable. Additionally, outstanding options 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 option holder's tenure as a director of Maker, or within 12
months after a 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 option holder other than by will or the
laws of descent and distribution, and each option is exercisable, during the
lifetime of the option holder, only by that option holder.


   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


                                       40

Management

<PAGE>

Incentive Plan is 2,600,000 shares plus annual cumulative increases on each
January 1 beginning in 2000 equal to 5% of Maker's issued and outstanding
common stock, calculated on a fully diluted basis, or 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 rules and regulations
which, 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 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 that 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 that 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 that 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 following twelve month period are automatically
accelerated.

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

     An option granted to any employee option holder who ceases to be an
employee of Maker or one of its subsidiaries shall terminate on the seventh day
following the date on which that option holder ceases to be an employee of
Maker or one of its subsidiaries. If that termination of employment is because
of dismissal for cause or because the employee is in breach of any employment
agreement, the option will terminate immediately on the date the option holder
ceases to be an employee of Maker or one of its subsidiaries. If that
termination of employment is because the option holder has become permanently
disabled, the option shall terminate on the last day of the twelfth month from
the date that option holder ceases to be an employee. In the event of the death
of the option holder, 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 option holder 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 the option has accrued and is in
effect on the date the option holder ceases to be an employee of Maker or one
of its subsidiaries. In the event of the death of any option holder, the option
may be exercised by the estate of the option holder, or by any person or
persons who acquired the right to exercise the option by bequest or inheritance
or by reason of the death of the option holder.

     The board of directors or 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 board of directors or
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 persons whose customary
employment is less than twenty hours per week or five months or less per year
and 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, 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 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 a date
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. These 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 these funds for the purchase of shares of
Maker's common stock in accordance with the Stock Purchase Plan, Maker may use
these 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 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 eighty-five percent (85%) of this 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 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.

     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 the Class B and Class C 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 rights 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.

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

                          DESCRIPTION OF CAPITAL STOCK

   
     Upon completion of the offering and the concurrent private placement, the
authorized capital stock of Maker will consist of 100,000,000 shares of common
stock, $.01 par value per share, of which 17,536,983 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. If shares of preferred stock are issued by Maker's board
of directors, the Amended and Restated Certificate of Incorporation eliminates
the rights of the holders of common stock to vote as a class on an increase or
decrease in the number of authorized shares of common stock. Holders of common
stock are entitled to receive ratably 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 holders of common stock upon liquidation. Holders
of common stock have no preemptive, subscription or redemption rights. There
are approximately 90 record holders of common stock.


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.


   
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."


Concurrent Private Placement

     In May 1999, Maker entered into a stock purchase agreement with Cisco.
Maker has agreed to sell 500,000 shares of common stock to Cisco at the initial
public offering price net of the underwriting discount. The stock purchase
agreement provides the following:
    


                                       47

                                                    Description of Capital Stock
<PAGE>

   
     Transfer Restrictions

     Cisco has agreed not to sell, transfer, encumber or otherwise dispose of
any of the common stock acquired in the concurrent private placement in a
public or private sale for a period of 180 days following the closing of the
concurrent private placement.

     Registration Rights

     During the period between the ten month anniversary and two year
anniversary of the closing of the concurrent private placement, Cisco may
require Maker to register all but not less than all of its shares of common
stock under the Securities Act.
    


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 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 66-2/3% 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.

Description of Capital Stock
<PAGE>

     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.

   
     The 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.
    


Transfer Agent and Registrar

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

                                       49

                         SHARES ELIGIBLE FOR FUTURE SALE

   
     Upon completion of the offering and the concurrent private placement,
Maker will have 17,536,983 outstanding shares of common stock. Of these shares,
the 3,000,000 shares offered hereby (3,525,000 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 14,536,983 shares of common stock outstanding upon closing of the
offering are "restricted securities" as that term is defined in Rule 144. Of
the remaining 14,536,983 shares, 13,907,782 shares are subject to lock-up
agreements (described below) and 500,000 shares will be subject to a lock-up
period of 180 days pursuant to the stock purchase agreement entered into with
Cisco in connection with the concurrent private placement.
    

     Beginning 90 days after commencement of the offering, approximately
12,870,000 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 13,809,711 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 1,684,531
shares) will be freely eligible for sale pursuant to Rule 144(k). In addition,
143,627 additional shares of common stock subject to outstanding vested stock
options 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
one percent of the number of shares of common stock then outstanding,
approximately 175,370 shares immediately after the completion of the offering
and the concurrent private placement or 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 stockholders owning upon completion of the offering, in the aggregate,
approximately 13,907,782 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 these 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 99,630 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 asconsideration 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.

Shares Eligible for Future Sale

     The holders of an aggregate of 5,054,433 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," "Certain Transactions--Registration
Rights Agreement" and "Description of Capital Stock--Concurrent Private
Placement."
    

     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
3,000,000 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 210 days with respect to one-third
of the shares, 180 days with respect to two-thirds of the shares, and 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 13,907,782 shares of
common stock and options to purchase an aggregate of 99,630 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. In
addition the 500,000 shares to be owned by Cisco following the concurrent
private placement will be subject to a lock-up arrangement for a period of 180
days. 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


                                       52

management and the consideration of the above factors in relation to market
valuation of companies in related businesses.

   
     The common stock has been 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

Maker. Certain legal matters in connection with the offering will be passed
upon for the underwriters by Testa, Hurwitz & Thibeault, LLP, Boston,

                   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.



                                                            ARTHUR ANDERSEN LLP

                   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:

             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
consisted of the following (in thousands):

(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.

                                                    ========      ========
</TABLE>

     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
principal and interest is due on June 30, 2001. Upon the occurrence of certain
events, LSI may convert the principal of the note into fully paid and

nonassessable shares of common stock of Maker at the lesser of $4.00 per share,
subject to certain dilutive events, as defined, or the subsequent sale price
per share of common stock issued by Maker in which the aggregate gross proceeds
received by Maker is at least $1,000,000. In April 1999, LSI notified Maker of
its intention to convert the note to 125,000 shares of Maker's common stock.
Such conversion will occur prior to or upon the closing of the proposed initial
public offering.

(7) Redeemable Preferred Stock

     (a) Class A Redeemable Preferred Stock

     In September 1996, Maker authorized the issuance of up to 5,380,000 shares
of Class A redeemable preferred stock, $.01 par value and issued 5,359,134
shares at $1.605 per share resulting in net proceeds of approximately
$8,537,000. In October 1997, Maker issued an additional 20,866 shares of Class
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.
These shares are nonvoting, nonconvertible and have dividend rights superior to
junior convertible preferred stock, Class B redeemable convertible preferred
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
31, 1999, the preference in liquidation and redemption value was approximately
$8,635,000. Class A redeemable preferred stock is redeemable according to the
following terms in order of occurrence: (i) upon the change in control of
Maker, as defined, (ii) 90 days following the completion of a qualified initial
public offering, as defined, or (iii) in three annual installments commencing

     (b) Class B Redeemable Convertible Preferred Stock

     In October 1997, Maker authorized the issuance of up to 3,416,670 shares
of Class B redeemable convertible preferred stock, $.01 par value, and issued
3,386,675 shares at $3.00 per share resulting in net proceeds of approximately
$10,098,000. In July 1998, Maker issued an additional 29,900 shares resulting
in net proceeds of approximately $89,000. These shares are convertible into
common stock at the rate of one share of common stock for each share of
preferred stock, adjustable for certain dilutive events. Conversion is
automatic upon the closing of an initial public offering of common stock at a
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
preference in liquidation and redemption value was approximately $10,249,000.
Class B redeemable convertible preferred stock is redeemable at the option of
the holder according to the following terms in order of occurrence: (i) upon
the change in control of Maker, as defined, or (ii) in three annual
installments commencing on September 30, 2002.

     (c) Class C Redeemable Convertible Preferred Stock

of Class C redeemable convertible preferred stock and issued 1,035,586 shares
at $4.40 per share resulting in net proceeds of approximately $4,526,000. In
January 1999, Maker sold an additional 102,272 shares of Class C redeemable
convertible preferred stock at $4.40 per share, resulting in net proceeds to
Maker of approximately $450,000. These shares are convertible into common stock
at the rate of one share of common stock for each share of preferred stock,
adjustable for certain dilutive events. Conversion is automatic upon the
closing of an initial public offering of common stock at a 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

(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
redeemable preferred stock and Class B convertible preferred stock and Class C
convertible preferred stock and superior to common

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.

     1999 Non-Employee 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.

Maker and LSI reached a settlement agreement under which Maker paid LSI a
lump-sum of $200,000 and issued a $500,000 convertible note as discussed in
Note 6. Maker has included in a separate line item in its consolidated
statement of operations the legal and settlement costs associated with the LSI

     Effective January 1, 1996, Maker adopted a 401(k) savings and
profit-sharing plan (the Plan). All employees are immediately eligible to
participate upon the attainment of age 21. The Plan is intended to qualify as a
defined contribution plan in accordance with Section 401(k) of the Internal
Revenue Code. Participants may defer up to 15% of their compensation under the
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 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

     The Delaware General Corporation Law, Maker's Amended and Restated
Certificate of Incorporation and Amended and Restated Bylaws and
indemnification agreements between Maker and its directors provide for
indemnification of its directors and officers for liabilities and expenses they
may incur in such capacities. In general, directors and officers are
indemnified with respect to actions taken in good faith in a manner reasonably
believed to be in, or not opposed to, Maker's best interests, and with respect
to any criminal action or proceeding, actions that the indemnitee had no
reasonable cause to believe were unlawful. Reference is made to Maker's Amended
and Restated Certificate of Incorporation and Amended and Restated Bylaws filed
as Exhibits 3.1 and 3.2 hereto, respectively.

     The Underwriting Agreement provides that the underwriters are obligated,
under certain circumstances, to indemnify directors, officers and controlling
persons of Maker against certain liabilities, including liabilities under the
Securities Act. Reference is made to the form of underwriting agreement filed
as Exhibit 1.1 hereto.

     Maker maintains directors and officers liability insurance for the benefit
of its directors and certain of its officers and has entered into
indemnification agreements with its directors and certain of its officers.

on Section 4(2) thereof and Regulation D promulgated thereunder, as
transactions by an issuer not involving a public offering. The granting of
stock options described in paragraph 6 above did not require registration under
the Securities Act, or an exemption therefrom, insofar as such grants did not
involve a "sale" of securities as such term is used in Section 2(3) of the
Securities Act. The sale of securities set forth in paragraph 7 above was
deemed to be exempt from the registration requirements of the Securities Act in
reliance on Rule 701 promulgated under Section 3(b) of the Securities Act as

relating to compensation as provided under such Rule 701.

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.

c/o LEHMAN BROTHERS INC.
Three World Financial Center

Ladies and Gentlemen:

     Maker Communications, Inc., a Delaware corporation (the "Company"),
proposes to sell 3,000,000 shares (the "Firm Stock") of the Company's Common
Stock, par value $.01 per share (the "Common Stock"). In addition, the Company
proposes to grant to the Underwriters named in Schedule 1 hereto (the
"Underwriters") an option to purchase up to an additional 525,000 shares of the
Common Stock on the terms and for the purposes set forth in Section 2 (the
"Option Stock"). The Firm Stock and the Option Stock, if purchased, are
hereinafter collectively called the "Stock." This is to confirm the agreement
concerning the purchase of the Stock from the Company by the Underwriters named
in Schedule 1 hereto (the "Underwriters"). You are acting as representatives
(the "Representatives") of the Underwriters and represent that the Underwriters
have authorized you to sign this Agreement on their behalf and to act in the
manner set forth in this Agreement.

         1. Representations, Warranties and Agreements of the Company. The
Company represents, warrants and agrees that:

         (a) A registration statement on Form S-1 and one or more amendments
     thereto with respect to the Stock has (i) been prepared by the Company in
     material conformity with the requirements of the United States Securities
     Act of 1933, as amended (the "Securities Act"), and the rules and
     regulations (the "Rules and Regulations") of the United States Securities
     and Exchange Commission (the "Commission") thereunder, (ii) been filed with
     the Commission under the Securities Act and (iii) become effective under
     the Securities Act. Copies of such registration statement and the
     amendments thereto have been delivered by the Company to the
     Representatives. (If you are the only Underwriters, all references herein
     to the Representatives shall be deemed to be to the Underwriters.) As used
     in this Agreement, "Effective Time" means the date and the time as of which
     such registration

<PAGE>

     statement, or the most recent post-effective amendment thereto, if any, was
     declared effective by the Commission; "Effective Date" means the date of
     the Effective Time; "Preliminary Prospectus" means each prospectus included
     in such registration statement, or amendments thereof, before it became
     effective under the Securities Act and any prospectus filed with the
     Commission by the Company pursuant to Rule 424(a) of the Rules and
     Regulations; "Registration Statement" means such registration statement, as
     amended at the Effective Time, including all information contained in the
     final prospectus filed with the Commission pursuant to Rule 424(b) of the
     Rules and Regulations in accordance with Section 5(a) hereof and deemed to
     be a part of the registration statement as of the Effective Time pursuant
     to paragraph (b) of Rule 430A of the Rules and Regulations; "Rule 462(b)
     Registration Statement" means any registration statement filed pursuant to
     Rule 462(b) of the Rules and Regulations, and after such filing, the term
     "Registration Statement" shall include the Rule 462(b) Registration
     Statement; and "Prospectus" means such final prospectus, as first filed
     with the Commission pursuant to paragraph (1) or (4) of Rule 424(b) of the
     Rules and Regulations. The Commission has not issued any order preventing
     or suspending the use of any Preliminary Prospectus.

         (b) The Registration Statement conforms, and the Prospectus and any
     further amendments or supplements to the Registration Statement or the
     Prospectus and any Rule 462(b) Registration Statement will, when they
     become effective or are filed with the Commission, as the case may be,
     conform in all material respects to the requirements of the Securities Act
     and the Rules and Regulations and do not and will not, as of the applicable
     effective date (as to the Registration Statement and any amendment thereto)
     and as of the applicable filing date (as to the Prospectus and any
     amendment or supplement thereto) contain an untrue statement of a material
     fact or omit to state a material fact required to be stated therein or
     necessary to make the statements therein not misleading; provided that no
     representation or warranty is made as to information contained in or
     omitted from the Registration Statement or the Prospectus in reliance upon
     and in conformity with written information furnished to the Company through
     the Representatives by or on behalf of any Underwriter specifically for
     inclusion therein. To the extent applicable, the copies of the Registration
     Statement and each other document referred to in subparagraph (a) above
     that have been or will be furnished to the Underwriters have been and will
     be identical to the electronically transmitted copies thereof filed with
     the Commission pursuant to the Commission's so called EDGAR system, except
     to the extent permitted by Regulation S-T and to the extent that certain
     information has been deleted therefrom pursuant to a request for
     confidential treatment under the Rules and Regulations.

         (c) The Company and each of its subsidiaries (as defined in Section 15)
     have been duly incorporated and are validly existing as corporations in
     good standing under the laws of their respective jurisdictions of
     incorporation, are duly qualified to do business and are in good standing
     as foreign corporations in each jurisdiction in which their respective
     ownership or lease of property or the conduct of their respective
     businesses requires such qualification, except where the failure to be so
     qualified or in good standing would not have a material adverse effect on
     the business, financial condition, shareholders' equity or results of
     operations of the Company and its subsidiaries taken as a whole (a
     "Material Adverse Effect"), and have all corporate power and authority
     necessary to own or hold their respective properties and to conduct the
     businesses in which they are engaged; and none of

                                       2

<PAGE>

     the subsidiaries of the Company is a "significant subsidiary", as such term
     is defined in Rule 405 of the Rules and Regulations.

         (d) The Company had an authorized and issued capitalization as set
     forth in the Prospectus as of the date stated therein, and all of the
     issued shares of capital stock of the Company have been duly and validly
     authorized and issued, are fully paid and non-assessable and conform in all
     material respects to the description thereof contained in the Prospectus;
     and all of the issued shares of capital stock of each subsidiary of the
     Company have been duly and validly authorized and issued and are fully paid
     and non-assessable and are owned directly or indirectly by the Company,
     free and clear of all liens, encumbrances, equities or claims.

         (e) The unissued shares of the Stock to be issued and sold by the
     Company to the Underwriters hereunder have been duly and validly authorized
     and, when issued and delivered against payment therefor as provided herein,
     will be duly and validly issued, fully paid and non-assessable; and the
     Stock will conform, in all material respects, to the description thereof
     contained in the Prospectus. Except as described in the Prospectus, there
     are no pre-emptive or other rights to subscribe for or to purchase, nor any
     restrictions upon the voting or transfer of any shares of Common Stock
     pursuant to the Company's corporate charter or by-laws or any agreement or
     other instrument to which the Company is a party.

         (f) This Agreement has been duly authorized, executed and delivered by
     the Company.

         (g) The execution, delivery and performance of this Agreement by the
     Company and the consummation of the transactions contemplated hereby and
     the issuance and delivery of the Stock will not conflict with or result in
     a breach or violation of any of the terms or provisions of, or constitute a
     default under, any indenture, mortgage, deed of trust, loan agreement or
     other agreement or instrument to which the Company or any of its
     subsidiaries is a party or by which the Company or any of its subsidiaries
     is bound or to which any of the property or assets of the Company or any of
     its subsidiaries is subject, nor will such actions create any security
     interest, lien, charge or encumbrance on any property or assets of the
     Company or any of its subsidiaries, nor will such actions result in any
     violation of the provisions of the charter or by-laws of the Company or any
     of its subsidiaries or any statute or any order, rule or regulation of any
     court or governmental agency or body having jurisdiction over the Company
     or any of its subsidiaries or any of their properties or assets; and except
     for the registration of the Stock under the Securities Act and such
     consents, approvals, authorizations, registrations or qualifications as may
     be required under the Exchange Act and applicable state securities laws or
     by the National Association of Securities Dealers, Inc. in connection with
     the purchase and distribution of the Stock by the Underwriters, no consent,
     approval, authorization or order of, or filing or registration or
     qualification of or with, any such court or governmental agency or body is
     required for the execution, delivery and performance of this Agreement by
     the Company and the consummation of the transactions contemplated hereby.

         (h) Except as described in the Registration Statement, there are no
     contracts, agreements or understandings between the Company and any person
     granting such person

                                       3
<PAGE>

     the right (other than rights which have been waived or satisfied) to
     require the Company to file a registration statement under the Securities
     Act with respect to any securities of the Company owned or to be owned by
     such person or to require the Company to include such securities in the
     securities registered pursuant to the Registration Statement or in any
     securities being registered pursuant to any other registration statement
     filed by the Company under the Securities Act.

         (i) Except as described in the Registration Statement, the Company has
     not sold or issued any shares of Common Stock during the six-month period
     preceding the date of the Prospectus, including any sales pursuant to Rule
     144A under, or Regulations D or S of, the Securities Act, other than shares
     issued pursuant to employee benefit plans, qualified stock options plans or
     other employee compensation plans or pursuant to outstanding options,
     rights or warrants.

         (j) Neither the Company nor any of its subsidiaries has sustained,
     since the date of the latest audited financial statements included in the
     Prospectus, any material loss or interference with its business from fire,
     explosion, flood or other calamity, whether or not covered by insurance, or
     from any labor dispute or court or governmental action, order or decree,
     otherwise than as set forth or contemplated in the Prospectus; and, since
     such date, there has not been any change in the capital stock or long-term
     debt of the Company or any of its subsidiaries or any material adverse
     change, or any development involving a prospective material adverse change,
     in or affecting the business, management, financial condition,
     stockholders' equity or results of operations of the Company and its
     subsidiaries taken as a whole (any of which, a "Material Adverse Change"),
     otherwise than as set forth in or contemplated by the Prospectus.

         (k) The financial statements (including the related notes and
     supporting schedules) filed as part of the Registration Statement or
     included in the Prospectus present fairly the financial condition and
     results of operations of the entities purported to be shown thereby, at the
     dates and for the periods indicated, and have been prepared in conformity
     with generally accepted accounting principles applied on a consistent basis
     throughout the periods involved.

         (l) Arthur Andersen LLP, which has certified certain financial
     statements of the Company, whose report appears in the Prospectus and who
     have delivered the initial letter referred to in Section 7(f) hereof, are
     independent public accountants as required by the Securities Act and the
     Rules and Regulations.

         (m) The Company and its subsidiaries own, or have valid rights to use,
     all items of real and personal property which are material to the business
     of the Company and its subsidiaries taken as a whole, free and clear of all
     security interests, liens, claims and encumbrances.

         (n) The Company and each of its subsidiaries own or possess adequate
     licenses or other rights to use all intellectual property rights, including
     patents, trademarks, service marks, trade names, trademark registrations,
     service mark registrations, copyrights and know-how necessary for the
     conduct of their respective businesses and have no reason to

                                       4
<PAGE>

     believe that the conduct of their respective businesses will conflict with,
     and have not received any notice of any claim of conflict with, any
     intellectual property rights of others.

         (o) Except as described in the Registration Statement, there are no
     legal or governmental proceedings pending to which the Company or any of
     its subsidiaries is a party or of which any property or assets of the
     Company or any of its subsidiaries is the subject which, if determined
     adversely to the Company or any of its subsidiaries, might have a Material
     Adverse Effect; and to the best of the Company's knowledge, no such
     proceedings are threatened by governmental authorities or others.

         (p) There are no contracts or other documents which are required to be
     described in the Prospectus or filed as exhibits to the Registration
     Statement by the Securities Act or by the Rules and Regulations which have
     not been described in the Prospectus or filed as exhibits to the
     Registration Statement or incorporated therein by reference as permitted by
     the Rules and Regulations.

         (q) No relationship, direct or indirect, exists between or among the
     Company on the one hand, and the directors, officers, stockholders,
     customers or suppliers of the Company on the other hand, which is required
     to be described in the Prospectus which is not so described.

         (r) Since the date as of which information is given in the Prospectus
     through the date hereof, and except as may otherwise be disclosed in the
     Prospectus, the Company has not (i) issued or granted any securities, (ii)
     incurred any liability or obligation, direct or contingent, other than
     liabilities and obligations which were incurred in the ordinary course of
     business, (iii) entered into any transaction not in the ordinary course of
     business or (iv) declared or paid any dividend on its capital stock.

         (s) Neither the Company nor any of its subsidiaries (i) is in violation
     of its charter or by-laws, (ii) is in default in any material respect, and
     no event has occurred which, with notice or lapse of time or both, would
     constitute such a default, in the due performance or observance of any
     term, covenant or condition contained in any material indenture, mortgage,
     deed of trust, loan agreement or other agreement or instrument to which it
     is a party or by which it is bound or to which any of its properties or
     assets is subject or (iii) is in violation in any material respect of any
     law, ordinance, governmental rule, regulation or court decree to which it
     or its property or assets may be subject or has failed to obtain any
     material license, permit, certificate, franchise or other governmental
     authorization or permit necessary to the ownership of its property or to
     the conduct of its business.

         (t) Neither the Company nor any subsidiary is an "investment company"
     within the meaning of such term under the Investment Company Act of 1940
     and the rules and regulations of the Commission thereunder.

         (u) Any certificate signed by an officer of the Company and delivered
     to the Underwriters or their counsel pursuant to this Agreement shall be
     deemed a representation and warranty hereunder by the Company to each
     Underwriter as to the matters covered thereby.

                                       5

         2. Purchase of the Stock by the Underwriters. On the basis of the
representations and warranties contained in, and subject to the terms and
conditions of, this Agreement, the Company agrees to sell 3,000,000 shares of
the Firm Stock to the several Underwriters and each of the Underwriters,
severally and not jointly, agrees to purchase the number of shares of the Firm
Stock set forth opposite that Underwriter's name in Schedule 1 hereto. The
respective purchase obligations of the Underwriters with respect to the Firm
Stock shall be rounded among the Underwriters to avoid fractional shares, as the
Representatives may determine.

         In addition, the Company grants to the Underwriters an option to
purchase up to 525,000 shares of Option Stock. Such option is granted for the
purpose of covering over-allotments in the sale of Firm Stock and is exercisable
as provided in Section 4 hereof. Shares of Option Stock shall be purchased
severally for the account of the Underwriters in proportion to the number of
shares of Firm Stock set opposite the name of such Underwriters in Schedule 1
hereto. The respective purchase obligations of each Underwriter with respect to
the Option Stock shall be adjusted by the Representatives so that no Underwriter
shall be obligated to purchase Option Stock other than in 100 share amounts. The
price of both the Firm Stock and any Option Stock shall be $_____ per share.

         The Company shall not be obligated to deliver any of the Stock to be
delivered on any Delivery Date (as hereinafter defined), as the case may be,
except upon payment for all the Stock to be purchased on such Delivery Date as
provided herein.

         3. Offering of Stock by the Underwriters.

         Upon authorization by the Representatives of the release of the Firm
Stock, the several Underwriters propose to offer the Firm Stock for sale upon
the terms and conditions set forth in the Prospectus.

         4. Delivery of and Payment for the Stock. Delivery of and payment for
the Firm Stock shall be made at the offices of Testa, Hurwitz & Thibeault, LLP,
Boston, Massachusetts, at 10:00 A.M., Eastern time, on the fourth full business
day following the date of this Agreement or at such other date or place as shall
be determined by agreement between the Representatives and the Company. This
date and time are sometimes referred to as the "First Delivery Date." On the
First Delivery Date, the Company shall deliver or cause to be delivered the Firm
Stock to the Representatives for the account of each Underwriter against payment
to or upon the order of the Company of the purchase price by wire transfer in
immediately available funds to a bank account designated by the Company. The
Company shall deliver the Firm Shares to Lehman Brothers Inc. through the
facilities of the Depository Trust Company ("DTC") for the respective accounts
of the several Underwriters. Time shall be of the essence, and delivery at the
time specified pursuant to this Agreement is a further condition of the

                      the Stock under the Securities Act and such consents,
                      approvals, authorizations, registrations or qualifications
                      as may be required under the Exchange Act and applicable
                      state securities laws or by the National Association of
                      Securities Dealers, Inc., no consent, approval,
                      authorization or order of, or filing or registration with,
                      any such court or governmental agency or body is required
                      for the execution, delivery and performance of this
                      Agreement by the Company and the consummation of the
                      transactions contemplated hereby;

                      (x) The statements contained in the Prospectus under the
                      captions "Description of Capital Stock" and "Shares
                      Eligible for Future Sale" are accurate and complete in all
                      material respects; and

                      (xi) To the best of such counsel's knowledge, there are no
                      contracts, agreements or understandings between the
                      Company and any person granting such person the right
                      (other than rights which have been waived or satisfied) to
                      require the Company to file a registration statement under
                      the Securities Act with respect to any securities of the
                      Company owned or to be owned by such person or to require
                      the Company to include such securities in the securities
                      registered pursuant to the Registration Statement or in
                      any securities being registered pursuant to any other
                      registration statement filed by the Company under the
                      Securities Act, except as described in the Registration
                      Statement.

         In rendering such opinion, such counsel may state that its opinion is
         limited to matters governed by the Federal laws of the United States of
         America, the laws of the Commonwealth of Massachusetts and the General
         Corporation Law of the State of Delaware and that such counsel is not
         admitted in the State of Delaware. Such counsel shall also have
         furnished to the Representatives a written statement, addressed to the
         Underwriters and dated such Delivery Date, in form and substance
         satisfactory to the Representatives, to the effect that (x) such
         counsel has acted as counsel to the Company on a regular basis, and has
         acted as counsel to the Company in connection with the preparation of
         the Registration Statement, and (y) such counsel has participated in
         the preparation of the Registration Statement and the Prospectus and in
         conferences with officers and other representatives of the Company,
         representatives of the independent public accountants for the Company
         and representatives of and counsel for the Company at which the
         contents of the Registration Statement and the Prospectus were
         discussed and, although such counsel has not independently verified and
         is not passing upon and does not assume any responsibility for the
         accuracy, completeness or fairness of the statements contained in the
         Registration Statement or the Prospectus (except as otherwise stated in
         the opinion of such counsel), on the basis and subject to the
         foregoing, no facts have come to the attention of such counsel which
         lead it to believe that the Registration Statement (except for the
         financial statements, supporting schedules and other financial data
         included therein or omitted therefrom, as to which no belief need be
         expressed), as of the Effective Date, contained any untrue statement of
         a material fact or omitted to state a material fact required to be
         stated therein or necessary in order to make the statements therein not
         misleading, or that the

                                       13
<PAGE>

         Prospectus (except for the financial statements, supporting schedules
         and other financial data included therein or omitted therefrom, as to
         which no belief need be expressed), at the time the Prospectus was
         issued or at the applicable Delivery Date, contains or contained any
         untrue statement of a material fact or omits or omitted to state a
         material fact required to be stated therein or necessary in order to
         make the statements therein, in light of the circumstances under which
         they were made, not misleading.

         (e) The Representatives shall have received from Testa, Hurwitz &
     Thibeault, LLP, counsel for the Underwriters, such opinion or opinions,
     dated such Delivery Date, with respect to the issuance and sale of the
     Stock, the Registration Statement, the Prospectus and other related matters
     as the Representatives may reasonably require, and the Company shall have
     furnished to such counsel such documents as they reasonably request for the
     purpose of enabling them to pass upon such matters.

         (f) At the time of execution of this Agreement, the Representatives
     shall have received from Arthur Andersen LLP a letter, in form and
     substance satisfactory to the Representatives, addressed to the
     Underwriters and dated the date hereof (i) confirming that they are
     independent public accountants within the meaning of the Securities Act and
     are in compliance with the applicable requirements relating to the
     qualification of accountants under Rule 2-01 of Regulation S-X of the
     Commission, (ii) stating, as of the date hereof (or, with respect to
     matters involving changes or developments since the respective dates as of
     which specified financial information is given in the Prospectus, as of a
     date not more than five days prior to the date hereof), the conclusions and
     findings of such firm with respect to the financial information and other
     matters ordinarily covered by accountants' "comfort letters" to
     underwriters in connection with registered public offerings.

         (g) With respect to the letter of Arthur Andersen LLP referred to in
     the preceding paragraph and delivered to the Representatives concurrently
     with the execution of this Agreement (the "initial letter"), the Company
     shall have furnished to the Representatives a letter (the "bring-down
     letter") of such accountants, addressed to the Underwriters and dated such
     Delivery Date (i) confirming that they are independent public accountants
     within the meaning of the Securities Act and are in compliance with the
     applicable requirements relating to the qualification of accountants under
     Rule 2-01 of Regulation S-X of the Commission, (ii) stating, as of the date
     of the bring-down letter (or, with respect to matters involving changes or
     developments since the respective dates as of which specified financial
     information is given in the Prospectus, as of a date not more than five
     days prior to the date of the bring-down letter), the conclusions and
     findings of such firm with respect to the financial information and other
     matters covered by the initial letter and (iii) confirming in all material
     respects the conclusions and findings set forth in the initial letter.

         (h) The Company shall have furnished to the Representatives a
     certificate, dated such Delivery Date, of its Chairman of the Board, its
     President or a Vice President and its chief financial officer stating that:

             (i) The representations, warranties and agreements of the Company
             in Section 1 are true and correct as of such Delivery Date; the
             Company has

                                       14
<PAGE>

             complied with all its agreements contained herein; and the
             conditions set forth in Sections 7(a) and 7(i) have been fulfilled;
             and

             (ii) They have carefully examined the Registration Statement and
             the Prospectus and, in their opinion (A) as of the Effective Date,
             the Registration Statement and Prospectus did not include any
             untrue statement of a material fact and did not omit to state a
             material fact required to be stated therein or necessary to make
             the statements therein not misleading, and (B) since the Effective
             Date no event has occurred which should have been set forth in a
             supplement or amendment to the Registration Statement or the
             Prospectus.

         (i) Neither the Company nor any of its subsidiaries shall have
     sustained since the date of the latest audited financial statements
     included in the Prospectus any loss or interference with its business from
     fire, explosion, flood or other calamity, whether or not covered by
     insurance, or from any labor dispute or court or governmental action, order
     or decree, otherwise than as set forth or contemplated in the Prospectus or
     (ii) since such date there shall not have been any change in the capital
     stock or long-term debt of the Company or any of its subsidiaries or any
     Material Adverse Change, otherwise than as set forth or contemplated in the
     Prospectus, the effect of which, in any such case described in clause (i)
     or (ii), is, in the judgment of the Representatives, so material and
     adverse as to make it impracticable or inadvisable to proceed with the
     public offering or the delivery of the Stock being delivered on such
     Delivery Date on the terms and in the manner contemplated in the
     Prospectus.

         (j) Subsequent to the execution and delivery of this Agreement there
     shall not have occurred any of the following: (i) trading in securities
     generally on the New York Stock Exchange or the American Stock Exchange or
     in the over-the-counter market, or trading in any securities of the Company
     on any exchange or in the over-the-counter market, shall have been
     suspended or minimum prices shall have been established on any such
     exchange or such market by the Commission, by such exchange or by any other
     regulatory body or governmental authority having jurisdiction, (ii) a
     banking moratorium shall have been declared by Federal or state
     authorities, (iii) the United States shall have become engaged in
     hostilities, there shall have been an escalation in hostilities involving
     the United States or there shall have been a declaration of a national
     emergency or war by the United States or (iv) there shall have occurred
     such a material adverse change in general economic, political or financial
     conditions (or the effect of international conditions on the financial
     markets in the United States shall be such) as to make it, in the judgment
     of a majority in interest of the several Underwriters, impracticable or
     inadvisable to proceed with the public offering or delivery of the Stock
     being delivered on such Delivery Date on the terms and in the manner
     contemplated in the Prospectus.

         (k) The Nasdaq National Market System shall have approved the Stock for
     inclusion, subject only to official notice of issuance.

         All opinions, letters, evidence and certificates mentioned above or
     elsewhere in this Agreement shall be deemed to be in compliance with the
     provisions hereof only if they are in form and substance reasonably
     satisfactory to counsel for the Underwriters.

         8. Indemnification and Contribution.

     (a) The Company shall indemnify and hold harmless each Underwriter, its
     officers and employees and each person, if any, who controls any
     Underwriter within the meaning of the Securities Act, from and against any
     loss, claim, damage or liability, joint or several, or any action in
     respect thereof (including, but not limited to, any loss, claim, damage,
     liability or action relating to purchases and sales of Stock), to which
     that Underwriter, officer, employee or controlling person may become
     subject, under the Securities Act or otherwise, insofar as such loss,
     claim, damage, liability or action arises out of, or is based upon, (i) any
     untrue statement or alleged untrue statement of a material fact contained
     in any Preliminary Prospectus, the Registration Statement or the Prospectus
     or in any amendment or supplement thereto, (ii) the omission or alleged
     omission to state in any Preliminary Prospectus, the Registration Statement
     or the Prospectus, or in any amendment or supplement thereto, or in any
     Blue Sky Application any material fact required to be stated therein or
     necessary to make the statements therein not misleading or (iii) any act or
     failure to act or any alleged act or failure to act by any Underwriter in
     connection with, or relating in any manner to, the Stock or the offering
     contemplated hereby, and which is included as part of or referred to in any
     loss, claim, damage, liability or action arising out of or based upon
     matters covered by clause (i) or (ii) above (provided that the Company
     shall not be liable under this clause (iii) to the extent that it is
     determined in a final judgment by a court of competent jurisdiction that
     such loss, claim, damage, liability or action resulted from any such acts
     or failures to act undertaken or omitted to be taken by such Underwriter
     through its gross negligence or willful misconduct), and shall reimburse
     each Underwriter and each such officer, employee or controlling person
     promptly upon demand for any legal or other expenses reasonably incurred by
     that Underwriter, officer, employee or controlling person in connection
     with investigating or defending or preparing to defend against any such
     loss, claim, damage, liability or action as such expenses are incurred;
     provided, however, that the Company shall not be liable in any such case to
     the extent that any such loss, claim, damage, liability or action arises
     out of, or is based upon, any untrue statement or alleged untrue statement
     or omission or alleged omission made in any Preliminary Prospectus, the
     Registration Statement or the Prospectus, or in any such amendment or
     supplement, in reliance upon and in conformity with written information
     concerning such Underwriter furnished to the Company through the
     Representatives by or on behalf of any Underwriter specifically for
     inclusion therein, which information consists solely of the information
     specified in Section 8(e); and provided, further, that the Company shall
     not be liable to any Underwriter under the indemnity agreement in this
     subsection with respect to any Preliminary Prospectus to the extent that
     any such loss, claim, damage, liability or any action in respect thereof of
     such Underwriter results from the fact that such Underwriter sold Stock to
     a person as to whom it shall be established that there was not sent or
     given, at or prior to the written confirmation of such sale, a copy of the
     Prospectus or of the Prospectus as then amended or supplemented in any case
     where such delivery is required by the Securities Act if the Company has
     previously furnished copies thereof in sufficient quantity to such
     Underwriter and the loss, claim, damage or liability of such Underwriter
     results from an untrue statement or omission of a material fact contained
     in the Preliminary Prospectus which was (i) identified to such Underwriter
     at or prior to the earlier of the filing with the Commission or the
     furnishing to such Underwriter of the Prospectus and (ii) corrected in the
     Prospectus or in the Prospectus as then amended or

                                       16
<PAGE>

     supplemented. The foregoing indemnity agreement is in addition to any
     liability which the Company may otherwise have to any Underwriter or to any
     officer, employee or controlling person of that Underwriter.

         (b) Each Underwriter, severally and not jointly, shall indemnify and
     hold harmless the Company, its officers and employees, each of its
     directors (including any person who, with his or her consent, is named in
     the Registration Statement as about to become a director of the Company),
     and each person, if any, who controls the Company within the meaning of the
     Securities Act, from and against any loss, claim, damage or liability,
     joint or several, or any action in respect thereof, to which the Company or
     any such director, officer or controlling person may become subject, under
     the Securities Act or otherwise, insofar as such loss, claim, damage,
     liability or action arises out of, or is based upon, (i) any untrue
     statement or alleged untrue statement of a material fact contained (A) in
     any Preliminary Prospectus, the Registration Statement or the Prospectus or
     in any amendment or supplement thereto, or (B) in any Blue Sky Application
     or (ii) the omission or alleged omission to state in any Preliminary
     Prospectus, the Registration Statement or the Prospectus, or in any
     amendment or supplement thereto, or in any Blue Sky Application any
     material fact required to be stated therein or necessary to make the
     statements therein not misleading, but in each case only to the extent that
     the untrue statement or alleged untrue statement or omission or alleged
     omission was made in reliance upon and in conformity with written
     information concerning such Underwriter furnished to the Company through
     the Representatives by or on behalf of that Underwriter specifically for
     inclusion therein, and shall reimburse the Company and any such director,
     officer or controlling person for any legal or other expenses reasonably
     incurred by the Company or any such director, officer or controlling person
     in connection with investigating or defending or preparing to defend
     against any such loss, claim, damage, liability or action as such expenses
     are incurred. The foregoing indemnity agreement is in addition to any
     liability which any Underwriter may otherwise have to the Company or any
     such director, officer, employee or controlling person.

         (c) Promptly after receipt by an indemnified party under this Section 8
     of notice of any claim or the commencement of any action, the indemnified
     party shall, if a claim in respect thereof is to be made against the
     indemnifying party under this Section 8, notify the indemnifying party in
     writing of the claim or the commencement of that action; provided, however,
     that the failure to notify the indemnifying party shall not relieve it from
     any liability which it may have under this Section 8 except to the extent
     it has been materially prejudiced by such failure and, provided further,
     that the failure to notify the indemnifying party shall not relieve it from
     any liability which it may have to an indemnified party otherwise than
     under this Section 8. If any such claim or action shall be brought against
     an indemnified party, and it shall notify the indemnifying party thereof,
     the indemnifying party shall be entitled to participate therein and, to the
     extent that it wishes, jointly with any other similarly notified
     indemnifying party, to assume the defense thereof with counsel reasonably
     satisfactory to the indemnified party. After notice from the indemnifying
     party to the indemnified party of its election to assume the defense of
     such claim or action, the indemnifying party shall not be liable to the
     indemnified party under this Section 8 for any legal or other expenses
     subsequently incurred by the indemnified party in connection with the
     defense thereof other than reasonable costs of investigation; provided,
     however, that the Representatives shall have the right to employ counsel to
     represent jointly the

                                       17
<PAGE>

     Representatives and those other Underwriters and their respective officers,
     employees and controlling persons who may be subject to liability arising
     out of any claim in respect of which indemnity may be sought by the
     Underwriters against the Company under this Section 8 if, in the reasonable
     judgment of the Representatives, it is advisable for the Representatives
     and those Underwriters, officers, employees and controlling persons to be
     jointly represented by separate counsel, and in that event the fees and
     expenses of such separate counsel shall be paid by the Company. No
     indemnifying party shall (i) without the prior written consent of the
     indemnified parties (which consent shall not be unreasonably withheld),
     settle or compromise or consent to the entry of any judgment with respect
     to any pending or threatened claim, action, suit or proceeding in respect
     of which indemnification or contribution may be sought hereunder (whether
     or not the indemnified parties are actual or potential parties to such
     claim or action) unless such settlement, compromise, consent or judgment
     (A) includes an unconditional release of each indemnified party from all
     liability arising out of such claim, action, suit or proceeding, and (B)
     does not include a statement as to or an admission of fault, culpability or
     failure to act by or on behalf of any indemnified party, or (ii) be liable
     for any settlement of any such action effected without its written consent
     (which consent shall not be unreasonably withheld), but if settled with the
     consent of the indemnifying party or if there be a final judgment for the
     plaintiff in any such action, the indemnifying party agrees to indemnify
     and hold harmless any indemnified party from and against any loss or
     liability by reason of such settlement or judgment.

         (d) If the indemnification provided for in this Section 8 shall for any
     reason be unavailable to or insufficient to hold harmless an indemnified
     party under Section 8(a) in respect of any loss, claim, damage or
     liability, or any action in respect thereof, referred to therein, then each
     indemnifying party shall, in lieu of indemnifying such indemnified party,
     contribute to the amount paid or payable by such indemnified party as a
     result of such loss, claim, damage or liability, or action in respect
     thereof, (i) in such proportion as shall be appropriate to reflect the
     relative benefits received by the Company on the one hand and the
     Underwriters on the other hand from the offering of the Stock 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 on the one hand and the Underwriters on the other hand with respect
     to the statements or omissions which resulted in such loss, claim, damage
     or liability, or action in respect thereof, as well as any other relevant
     equitable considerations. The relative benefits received by the Company on
     the one hand and the Underwriters on the other hand with respect to such
     offering shall be deemed to be in the same proportion as the total net
     proceeds from the offering of the Stock purchased under this Agreement
     (before deducting expenses) received by the Company, on the one hand, and
     the total underwriting discounts and commissions received by the
     Underwriters with respect to the shares of the Stock purchased under this
     Agreement, on the other hand, bear to the total gross proceeds from the
     offering of the shares of the Stock under this Agreement, in each case as
     set forth in the table on the cover page of the Prospectus. The relative
     fault shall be determined by reference to whether the untrue or alleged
     untrue statement of a material fact or omission or alleged omission to
     state a material fact relates to information supplied by the Company on the
     one hand or the Underwriters on the other hand, the intent of the parties
     and their relative knowledge, access to information and opportunity to
     correct or prevent such statement or omission. The Company and the
     Underwriters agree that it would not be just and equitable if contributions
     pursuant to this Section 8 were to be determined by pro rata

                                       18
<PAGE>

     allocation (even if the Underwriters were treated as one entity for such
     purpose) or by any other method of allocation which does not take into
     account the equitable considerations referred to herein. The amount paid or
     payable by an indemnified party as a result of the loss, claim, damage or
     liability, or action in respect thereof, referred to above in this Section
     8 shall be deemed to include, for purposes of this Section 8(d), any legal
     or other expenses reasonably incurred by such indemnified party in
     connection with investigating or defending any such action or claim.
     Notwithstanding the provisions of this Section 8(d), no Underwriter shall
     be required to contribute any amount in excess of the amount by which the
     total price at which the Stock underwritten by it and distributed to the
     public was offered to the public exceeds the amount of any damages which
     such Underwriter has otherwise paid or become liable to pay by reason of
     any untrue or alleged untrue statement or omission or alleged omission. No
     person 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 guilty of such fraudulent misrepresentation. The
     Underwriters' obligations to contribute as provided in this Section 8(d)
     are several in proportion to their respective underwriting obligations and
     not joint.

         (e) The Underwriters severally confirm that the following statements
     are correct and constitute the only information concerning such
     Underwriters furnished in writing to the Company by or on behalf of the
     Underwriters specifically for inclusion in the Registration Statement and
     the Prospectus: (i) the statements with respect to the public offering of
     the Stock by the Underwriters set forth on the cover page of the Prospectus
     and (ii) the statements concerning concessions, allowances and reallowances
     and stabilization and over-allotment set forth under the caption
     "Underwriting" in the Prospectus.

         9. Defaulting Underwriters.

         If, on either Delivery Date, any Underwriter defaults in the
performance of its obligations under this Agreement, the remaining
non-defaulting Underwriters shall be obligated to purchase the Stock which the
defaulting Underwriter agreed but failed to purchase on such Delivery Date in
the respective proportions which the number of shares of the Firm Stock set
opposite the name of each remaining non-defaulting Underwriter in Schedule 1
hereto bears to the total number of shares of the Firm Stock set opposite the
names of all the remaining non-defaulting Underwriters in Schedule 1 hereto;
provided, however, that the remaining non-defaulting Underwriters shall not be
obligated to purchase any of the Stock on such Delivery Date if the total number
of shares of the Stock which the defaulting Underwriter or Underwriters agreed
but failed to purchase on such date exceeds 9.09% of the total number of shares
of the Stock to be purchased on such Delivery Date, and any remaining
non-defaulting Underwriter shall not be obligated to purchase more than 110% of
the number of shares of the Stock which it agreed to purchase on such Delivery
Date pursuant to the terms of Section 2. If the foregoing maximums are exceeded,
the remaining non-defaulting Underwriters, or those other underwriters
satisfactory to the Representatives who so agree, shall have the right, but
shall not be obligated, to purchase, in such proportion as may be agreed upon
among them, all the Stock to be purchased on such Delivery Date. If the
remaining Underwriters or other underwriters satisfactory to the Representatives
do not elect to purchase the shares which the defaulting Underwriter or
Underwriters agreed but failed to purchase on such Delivery Date, this Agreement
(or, with respect to the Subsequent Delivery Date, the obligation of the
Underwriters to purchase, and of the Company to sell, the Option Stock) shall
terminate without liability on the part

                                       19
<PAGE>

of any non-defaulting Underwriter or the Company, except that the Company will
continue to be liable for the payment of expenses to the extent set forth in
Sections 6 and 11. As used in this Agreement, the term "Underwriter" includes,
for all purposes of this Agreement unless the context requires otherwise, any
party not listed in Schedule 1 hereto who, pursuant to this Section 9, purchases
Firm Stock which a defaulting Underwriter agreed but failed to purchase.

         Nothing contained herein shall relieve a defaulting Underwriter of any
liability it may have to the Company for damages caused by its default. If other
underwriters are obligated or agree to purchase the Stock of a defaulting or
withdrawing Underwriter, either the Representatives or the Company may postpone
the Delivery Date for up to seven full business days in order to effect any
changes that in the opinion of counsel for the Company or counsel for the
Underwriters may be necessary in the Registration Statement, the Prospectus or
in any other document or arrangement.

         10. Termination. The obligations of the Underwriters hereunder may be
terminated by the Representatives by notice given to and received by the Company
prior to delivery of and payment for the Firm Stock if, prior to that time, any
of the events described in Sections 7(i) or 7(j) shall have occurred or if the
Underwriters shall decline to purchase the Stock for any reason permitted under
this Agreement.

         11. Reimbursement of Underwriters' Expenses. If the Company shall fail
to tender the Stock for delivery to the Underwriters by reason of any failure,
refusal or inability on the part of the Company to perform any agreement on its
part to be performed, or because any other condition of the Underwriters'
obligations hereunder required to be fulfilled by the Company is not fulfilled,
the Company will reimburse the Underwriters for all reasonable out-of-pocket
expenses (including fees and disbursements of counsel) incurred by the
Underwriters in connection with this Agreement and the proposed purchase of the
Stock, and upon demand the Company shall pay the full amount thereof to the
Representatives. If this Agreement is terminated pursuant to Section 9 by reason
of the default of one or more Underwriters, the Company shall not be obligated
to reimburse any defaulting Underwriter on account of those expenses.

         12. Notices, etc. All statements, requests, notices and agreements
hereunder shall be in writing, and:

         (a) if to the Underwriters, shall be delivered or sent by mail, telex
         or fax to Lehman Brothers Inc., Three World Financial Center, New York,

receipt thereof. The Company shall be entitled to act and rely upon any request,
consent, notice or agreement given or made on behalf of the Underwriters by
Lehman Brothers Inc. on behalf of the Representatives.

         13. Persons Entitled to Benefit of Agreement. This Agreement shall
inure to the benefit of and be binding upon the Underwriters, the Company, and
their respective successors. This Agreement and the terms and provisions hereof
are for the sole benefit of only those persons, except that (A) the

and agreements of the Company and the Underwriters contained in this Agreement
or made by or on behalf on them, respectively, pursuant to this Agreement, shall
survive the delivery of and payment for the Stock and shall remain in full force
and effect, regardless of any investigation made by or on behalf of any of them
or any person controlling any of them.

         15. Definition of the Terms "Business Day" and "subsidiary". For
purposes of this Agreement, (a) "business day" means each Monday, Tuesday,
Wednesday, Thursday or Friday which is not a day on which banking institutions
in New York are generally authorized or obligated by law or executive order to
close and (b) "subsidiary" has the meaning set forth in Rule 405 of the Rules
and Regulations.

         16. Governing Law. This Agreement shall be governed by and construed in

                     share, and 1,000,000 shares of Preferred Stock, par value
                     $.01 per share.

           3.        When issued and sold under the circumstances contemplated
                     in the Registration Statement, the shares of Common Stock
                     offered by the Company will be duly authorized, validly

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.

6.0     PURCHASE ORDERS

6.1     Buyer shall order NRE Services by issuing written purchase orders.
        Purchase orders for NRE Services will be deemed accepted by IBM unless
        rejected in writing by IBM, specifying the reasons for rejection. IBM
        shall make reasonable efforts to make any such rejection within [**]
        calendar days, but in no case later than [**] calendar days after IBM's
        receipt of such purchase order.

6.2     Buyer shall order Products by issuing written purchase orders. Purchase
        orders for Products must be received by IBM in advance, with at least
        the Purchase Order Lead Time specified in Attachment C, to allow IBM to
        meet Buyer's requested Shipment Date. Requested Shipment Dates will be
        deemed accepted (subject to the Purchase Order Lead Time) by IBM, unless
        IBM provides buyer with written notice of IBM's rejection of such
        purchase order. IBM shall make reasonable efforts to make any such
        rejection within [**] calendar days, but in no case later than [**]
        calendar days after IBM's receipt of such purchase order. If so
        accepted, a requested Shipment Date shall constitute a Scheduled
        Shipment Date. Subject to IBM's written acceptance, Buyer may request an
        improved Scheduled Shipment Date. Such acceptance shall not be
        unreasonably withheld by IBM.

6.3     Purchase orders for Products will be deemed accepted by IBM unless
        rejected in writing by IBM, specifying the reasons for rejection. IBM
        shall make reasonable efforts to make any such rejection within [**]
        calendar days, but in no case later than [**] calendar days after IBM's
        receipt of such purchase order. Purchase orders for Products may only be
        rejected by IBM if such purchase order requests (i) a quantity of
        Products that exceeds the most recent Product demand forecast accepted
        by IBM; or (ii) requests a shipment date inconsistent with Purchase
        Order Lead Time; or (iii) does not comply with the terms and conditions
        of this Agreement, or (iv) if Buyer is in breach of this Agreement and
        beyond the cure period.

6.4     Purchase orders issued to IBM shall include the following:

        6.4.1 NRE Services and/or Product(s) being ordered;

        6.4.2  quantity  of units of Product  requested  (in  increments  of the
        minimum ship pack quantity ("SPQ") only);

        6.4.3 NRE Charges and/or unit price per Attachment C;

        6.4.4 billing address;

        6.4.5 shipping instructions,  including carrier, destination address and
        requested shipment dates; and

        6.4.6 reference to this Agreement and Agreement Number.

6.5     This Agreement shall take precedence over and govern in case of any
        additional, different or conflicting terms and conditions in any
        purchase order(s) or any other form of either party. Purchase orders and
        other forms of either party may not vary the terms of this Agreement.
        Additional, different or conflicting terms and conditions on a purchase
        order or other form shall be of no effect, unless in writing and signed
        by both parties.

6.6     Notwithstanding any other provision of this Agreement, in the event that
        IBM's ability to supply the Product is constrained (except as caused by
        Buyer) for reasons which include, but are not limited to, component
        availability, and the Scheduled Shipment Date cannot be met, IBM will
        reduce the quantities of Products to be supplied to Buyer in proportion
        to the reduction in quantities of products of the same technology or
        utilizing the same manufacturing process to be supplied to satisfy
        others. Receipt of such allocated supply and later delivery of all
        undelivered ordered quantities after the constraint ends shall
        constitute Buyer's exclusive remedy in the event of such supply
        constraint.

7.0     PRICING

7.1     Buyer shall pay IBM the NRE Charge applicable to such Product as set
        forth in Attachment C, as well as other sums for special services as are
        separately ordered by Buyer and listed or referenced in Attachment C, or
        as otherwise agreed to in writing by the parties.

7.2     The unit price for each unit of Product ordered shall be determined at
        the time the applicable purchase order is accepted using the Product's
        Price Quantity Matrix set forth in Attachment C. The quantity used as an
        input into such Price Quantity Matrix shall be the cumulative quantity
        of units of a Products determined by the purchase orders accepted by IBM
        after the Commencement Date, including the units of Product requested in
        the purchase order that is the subject of such price determination.

8.0     TITLE AND SHIPMENT

8.1     Title and risk of loss for a Product pass to Buyer when IBM delivers the
        Product to the carrier.

8.2     Products shall be shipped from the manufacturing location FOB for
        domestic U.S. destinations and ExWorks (as defined in the 1990 INCO
        Terms) for international shipments.

8.3     In no event shall IBM be deemed to assume any liability in connection
        with any shipment, nor shall the carrier be construed as an agent of
        IBM.

9.0     INVOICING, PAYMENT TERMS, TAXES

9.1     NRE Charges shall accrue and be invoiced on the schedule set forth in
        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
        taxing jurisdiction to recognize any Buyer reseller's exemption
        certificate, or from Buyer's failure to have a valid reseller's
        exemption certificate. If Buyer purchases Product under this Agreement
        for internal use, Buyer agrees to notify IBM and pay applicable sales
        tax.

10.0    INTEREST ON OVERDUE PAYMENTS

        Late payment of invoices will be assessed a charge equal to the lesser
        of one and one-half (1.5%) per month or the statutorily maximum rate of
        interest in accordance with the laws of the State of New York.

11.0    CANCELLATION CHARGES, RESCHEDULING, ORDER CHANGE PROVISIONS AND END OF
        LIFE NOTICE

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.

11.3    In the event that IBM determines to discontinue the manufacture of a
        Product, IBM will provide Customer with at least [**] prior written
        notice of any such discontinuance. Customer shall place any and all
        orders for such Product within [**] after it receives such notice.
        Customer must take final delivery of all Product under any such orders
        on or before the date that IBM has notified Customer that such Product
        will be discontinued. All such orders will be completed and filled by
        IBM in the ordinary course of business and in accordance with the terms
        of this Agreement.

12.0    ENGINEERING CHANGES

12.1    IBM may implement Mandatory Engineering Changes. IBM will provide Buyer
        written notice of any Mandatory Engineering Changes that affect form,
        fit, or function of the Product as soon as reasonably possible.

12.2    For all previously shipped Product not incorporating Mandatory
        Engineering Changes, IBM may provide replacement Products (including
        parts, materials and documentation) [**]. Buyer must use reasonable
        efforts to install Mandatory Engineering Changes on all Products in its
        inventory. If IBM requests the return of Products displaced by
        installation of replacement Products, Buyer will promptly return any
        displaced Products to IBM's designated U.S. location after installation
        of such replacement Products, [**].

12.3    In addition to Mandatory Engineering Changes, IBM may implement
        Engineering Changes that result in cost reductions to the Product
        ("Elective Engineering Changes") with prior written approval from Buyer.
        Such approval shall not be unreasonably withheld. IBM shall give Buyer
        prompt written notice of Elective Engineering Changes. [**]

12.4    IBM may make available other Engineering Changes ("Optional Engineering
        Changes"). The cost of any Optional Engineering Changes that Buyer
        desires to implement will be borne by Buyer and will be determined
        through a written request for quote process.

13.0    TERMINATION OF AGREEMENT

13.1    If either party is in material default of a provision of this Agreement
        and such default is not corrected within thirty (30) days of receipt of
        written notice, this Agreement may be terminated by the party not in
        default.

        13.1.1 If Buyer terminates due to IBM default, all previously accepted
        purchase orders shall be automatically canceled without charge to Buyer,
        except for any specific purchase order(s) that the parties mutually
        agree in writing not to cancel.
          
        13.1.2 If IBM terminates due to Buyer default, at IBM's discretion, all
        previously accepted purchase orders shall be automatically canceled and
        adjustment charges and cancellation charges will apply in addition to
        any other amounts then due.

13.2    Notwithstanding the provisions of Section 13.1, either party shall have
        the right to terminate this Agreement immediately if:

        13.2.1 The other party files a petition in bankruptcy, undergoes a
        reorganization pursuant to a petition in bankruptcy, is adjudicated a
        bankrupt, becomes insolvent, becomes dissolved or liquidated, files a
        petition for dissolution or liquidation, makes an assignment for benefit
        of creditors, or has a receiver appointed for its business; or

        3.2.2 The other party is subject to property attachment or court
        injunction or court order which has a substantial negative effect on its
        ability to fulfill its material obligations under this Agreement.

13.3    IBM may terminate this Agreement, or its obligations with respect to
        specifically affected Products, immediately if:

        13.3.1 Buyer unreasonably withholds its consent for IBM to make Elective
        Engineering Changes under Section 12.0; or

        13.3.2 Either party receives a claim or charge, or otherwise has a
        reasonable basis to believe any time during the term of this Agreement,
        that any of the other parties Deliverable Items infringe third party
        intellectual property rights.

13.4    In the event this Agreement is terminated pursuant to Section 13.1.2,
        13.2 or 13.3, all amounts due and payable to the non-terminating party
        as of the date of such termination shall become immediately due and
        payable.

13.5    Either party may terminate this Agreement without cause upon twelve (12)
        months prior written notice to the other. If Buyer is the terminating
        party, all previously accepted purchase orders will be filled, but IBM
        shall not be obligated to accept further purchase orders after receiving
        notice. If IBM is the terminating party, IBM will continue to accept new
        purchase orders pursuant to Section 6.0 during the notice period.

13.6    All Products shipped against accepted purchase orders will be subject to
        the terms and conditions of this Agreement notwithstanding any
        termination or expiration of the term of this Agreement.

13.7    Within thirty (30) days after filling all outstanding purchase orders
        after termination, IBM shall provide Buyer with a refund of any net
        credit remaining after all amounts due have been applied.

14.0    WARRANTIES

14.1    IBM warrants that each unit of Product after delivery will be free from
        defects in material and workmanship and will conform to the Product
        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

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.

26.0    GENERAL PROVISIONS

26.1    This Agreement may be executed in any number of identical counterparts,
        each of which shall be deemed to be an original, and all of which
        together shall be deemed to be one and the same instrument when each
        party has signed one such counterpart.

26.2    The activities of each party and its employees, agents or
        representatives while on the other party's premises (including any
        design center) shall comply with the host company's policies and
        procedures for such facilities, including security procedures and
        visitation guidelines.

26.3    Each party will comply with all applicable federal, state and local
        laws, regulations and ordinances including, without limitation, the
        regulations of the U.S. Government relating to the export of commodities
        and technical data insofar as they relate to the activities under this
        Agreement. Buyer agrees that machines, commodities, and technical data
        provided under this Agreement are subject to restrictions under the
        export control laws and regulations of the United States of America,
        including, without limitation, the U.S. Export Administration Act and
        the U.S. Export Administration Regulations. Buyer hereby gives its
        written assurance that neither machines, commodities or technical data
        provided by IBM under this Agreement, nor the direct product thereof,
        will be exported, or re-exported, directly or indirectly, to prohibited
        countries or nationals thereof without first obtaining applicable
        government approval. Buyer agrees it is responsible for obtaining
        required government documents and approvals prior to export of any
        machine, commodity, or technical data.

26.4    This Agreement shall be construed, and the legal relations between the
        parties hereto shall be determined, in accordance with the substantive
        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
        expresses the intent of the parties. If the intent of the parties cannot
        be preserved, this Agreement shall be either renegotiated or terminated.

26.6    No actions, regardless of form, arising out of this Agreement, may be
        brought by either party more than two (2) years after the cause of
        action has arisen, or, in the case of nonpayment, more than two (2)
        years from the date the last payment was due.

26.7    This Agreement may be modified only by a written amendment signed by
        persons authorized to so bind Buyer and IBM. This Agreement shall not be
        supplemented or modified by any course of dealing, course of performance
        or trade usage. The term "this Agreement" as used herein includes any
        applicable Attachments or future written amendment(s) made in accordance
        with this Section.

26.8    Failure by either party to insist in any instance on strict conformance
        by the other to any term of this Agreement or failure by either party to

        waiver of any subsequent breach of the same or of any other term
        contained in this Agreement.

        or termination of this Agreement shall remain in effect beyond any

                            STOCK PURCHASE AGREEMENT

     THIS STOCK PURCHASE AGREEMENT is made as of the 5th day of May 1999, by and
between Maker Communications, Inc., a Delaware corporation (the "Company") and
Cisco Systems, Inc., a California corporation (the "Investor").

     WHEREAS, the Investor has indicated a desire to purchase 500,000 shares of
Common Stock from the Company.

     WHEREAS, the Company has indicated a desire to sell 500,000 shares of
Common Stock to the Investor and has agreed to register such shares under the
Securities Act of 1933, as amended (the "Securities Act"), on the terms set
forth herein.

     WHEREAS, the Company and the Investor have agreed that this Agreement shall
constitute the entire understanding and agreement between the parties with
regard to the subject matter hereof.


        NOW, THEREFORE, THE PARTIES HEREBY AGREE AS FOLLOWS:

     1. Purchase and Sale of Stock.

        1.1 Sale and Issuance of Stock. Subject to the terms and conditions of
this Agreement, the Company agrees to sell to the Investor and the Investor
agrees to purchase from the Company 500,000 shares of the Company's Common Stock
(the "Stock"), having the rights, preferences, privileges and restrictions set
forth in the Amended and Restated Certificate of Incorporation of the Company
(the "Restated Certificate") to be filed with the Delaware Secretary of State
prior to the Closing (as defined below).

        1.2 The Closing. The purchase and sale of the Stock shall be held at the
Company's offices concurrently with the closing of the Company's initial public
offering (the "IPO") or, if later, upon satisfaction or waiver of each of the
conditions set forth in Sections 4 and 5 (the "Closing"). At the Closing, the
Company will deliver the Stock to the Investor against payment of the purchase
price therefor by check payable to the order of the Company or by wire transfer.
The per share purchase price for the Stock shall be equal to the per share price
paid by the public for the Company's Common Stock in the IPO, less any
underwriter discounts and commissions.

     2. Representations and Warranties of the Company. The Company hereby
represents and warrants to the Investor that:

        2.1 Organization and Good Standing. The Company is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Delaware and has all requisite corporate power and authority to carry on its
business as now conducted.

        2.2 Authorization. All corporate action on the part of the Company, its
officers, directors and stockholders necessary for the authorization, execution
and delivery of this

                                       1
<PAGE>

Agreement, the performance of all obligations of the Company hereunder, and the
authorization, issuance and delivery of the Stock has been taken or will be
taken prior to the Closing, subject to laws of general application relating to
bankruptcy, insolvency and the relief of debtors and by general principles of
equity.

        2.3 Valid Issuance of Stock. The Stock, when issued, sold and delivered
in accordance with the terms hereof for the consideration expressed, will be
duly and validly issued, fully paid and nonassessable and, based in part upon
the representations of the Investor in this Agreement, will be issued in
compliance with all applicable federal and state securities laws.

        2.4 Litigation. Except as set forth in the Company's registration
statement prepared in connection with the IPO, as filed with the Securities and
Exchange Commission ("SEC") and amended from time to time (the "Registration
Statement"), there are no actions, proceedings or investigations pending or, to
the best of Company's knowledge, any basis therefor or threat thereof, against
or affecting the Company, that, either in any case or in the aggregate, would
result in any material adverse change in the business, financial condition, or
results of operations of the Company.

        2.5 Properties. To the best of the Company's knowledge (but without
having conducted any special investigation), the Company has (i) good and
marketable title to its properties and assets and has good title to all its
leasehold interests, and (ii) sufficient title, license and/or ownership of all
patents, trademarks, service marks, trade names, copyrights, trade secrets,
information, proprietary rights and processes necessary for its business as now
conducted on the date hereof.

        2.6 Compliance with Other Documents. The execution and delivery of this
Agreement, consummation of the transactions contemplated hereby, and compliance
with the terms and provisions hereof will not conflict with or result in a
breach of the terms and conditions of, or constitute a default under the
Restated Certificate or Bylaws of the Company or of any contract or agreement to
which the Company is now a party, except where such conflict, breach or default
of any such contract or agreement, either individually or in the aggregate,
would not have a material adverse effect on the Company's business, financial
condition or results of operations.

     3. Representations and Warranties of the Investor. The Investor hereby
represents and warrants that:

        3.1 Authorization. This Agreement constitutes the valid and legally
binding obligation of the Investor, enforceable in accordance with its terms,
subject to laws of general application relating to bankruptcy, insolvency and
the relief of debtors and by general principles of equity.

        3.2 Investigation. The Investor acknowledges that it has had an
opportunity to discuss the business, affairs and current prospects of the
Company with the Company's president. The Investor further acknowledges having

        6.1 Agreement Not to Transfer.

            (a) Prior to the date 180 days after the date of the Closing, the
Investor shall not, directly or indirectly, Transfer or offer to Transfer any
shares of the Stock other than to affiliates who agree to be bound by the terms
of this Agreement, unless the Company consents to such Transfer and the
transferee agrees to be bound by this Agreement.

            (b) In order to enforce the Transfer Restrictions, the Company may
impose stop-transfer instructions with respect to the Stock until the end of the
restricted period.

            (c) As used in this Agreement, the term "Transfer" shall mean any
sale, transfer, assignment, hypothecation, encumbrance or other disposition,
whether voluntary or involuntary, of shares of the Stock. In the case of a
hypothecation, the Transfer shall be deemed to occur both at the time of the
initial pledge and at any pledgee's sale or a sale by any secured creditor or a
retention by the secured creditor of the pledged shares of the Stock in complete
or partial satisfaction of the indebtedness for which the shares of the Stock
are security.

        6.2 Market Stand-Off. In addition to the Transfer Restrictions (which
shall in no way be limited by the following), in connection with any
underwritten public offering by the Company of its equity securities pursuant to
an effective registration statement filed under the Securities Act, the Investor
shall not Transfer or offer to Transfer any shares of the Stock without the
prior written consent of the Company and its underwriters. Such restriction (the
"Market Stand-Off") shall be in effect for such period of time from and after
the effective date of the final prospectus for the offering as may be requested
by the Company or such underwriters; provided, however, that (i) such Market
Stand-Off shall not exceed one hundred eighty (180) days, and (ii) the Investor
shall be subject to the Market Stand-Off only if the officers, directors and
other stockholders of the Company are also subject to similar restrictions. In
order to enforce the Market Stand-Off, the Company may impose stop-transfer
instructions with respect to the Stock until the end of the applicable stand-off
period.

        6.3 Registration of Stock. The Company agrees that, upon request by the
Investor, it will effect registration of the Stock in accordance with the
provisions contained in Exhibit A attached hereto. The Investor understands and
agrees that (i) the Stock will be characterized as "restricted securities" under
the federal securities laws inasmuch as it is being acquired from the Company in
a transaction not involving a public offering and that under such laws and
applicable regulations such securities may be resold without registration under
the Securities Act only in certain limited circumstances, and (ii) each
certificate representing the Stock and any other securities issued in respect of
the Stock upon any stock split, stock dividend, recapitalization, merger or
similar event (unless no longer required in the opinion of counsel for

                                       4
<PAGE>

the Company) shall be stamped or otherwise imprinted with appropriate legends
mandated by federal and state securities laws.

split, stock dividend, recapitalization or reorganization distributed with

remedies, obligations, or liabilities under or by reason of this Agreement,
except as expressly provided in this Agreement. Notwithstanding anything to the
contrary contained herein, the covenants set forth in Section 6 shall not be
binding upon any entity (other than an affiliate of the Investor) which acquires
any shares of the Stock or a Stock Distribution in a transaction permitted
hereunder.

        7.4 Entire Agreement. This Agreement constitutes the entire
understanding and agreement between the parties with regard to the subject
matter hereof.

        7.5 Notices. Except as otherwise provided, all notices and other

a particular instance and either retroactively or prospectively) only with the
written consent of the Company and the Investor.

arbitration proceeding in relation to this Agreement or the Stock or any Stock

of all, but not less than all, such Stock on Form S-3 and all such
qualifications and compliances as may be so requested and as would permit or
facilitate the sale and distribution of all of the Stock. The Company shall have
no obligation to effect any registration of less than all of the Stock.

            (b) Notwithstanding anything to the contrary in this Section 1.2,
the Company shall not be obligated to effect any such registration,
qualification or compliance, pursuant to this Section 1.2: (i) if the Company
shall furnish to the Investor a certificate signed by the President of the
Company stating that, in the good faith judgment of the Board of Directors of
the Company, such registration should be deferred due to material events
directly relating to the Company, in which event the Company shall have the
right to defer the filing of the Form S-3 for a period of not more than 90 days
after receipt of the request of the Investor under this Section 1.2 (provided,
however, that the Company may defer such registration only

                                      A-1
<PAGE>

once); or (ii) in any particular jurisdiction in which the Company would be
required to qualify to do business or to execute a general consent to service of
process in effecting such registration, qualification or compliance.

            (c) If Form S-3 is not available to the Company to effect the
registration of the Stock as contemplated by this Section 1.2, then (i) the
Company shall effect such registration on Form S-1 and (ii) in such event, all
references in this Section 1 to Form S-3 shall be read as references to Form
S-1.

            (d) The Company shall not be obligated to effect, or to take any
action to effect, any registration pursuant to this Section 1.2 after the
earlier to occur of the following events: (i) the Company has effected one
registration pursuant to this Section 1.2, and such registration has been
declared or ordered effective and otherwise satisfies and continues to satisfy
the terms and conditions of this Section 1.2; or (ii) the Company has
voluntarily effected the registration of all of the Stock without having first
received a request for such registration pursuant to this Section 1.2 (a
"Voluntary Registration"), and such Voluntary Registration has been declared or
ordered effective and otherwise satisfies and continues to satisfy the terms and
conditions of this Section 1.2.

        1.3 Obligations of the Company. Whenever required under Section 1.2 to
effect the registration on Form S-3 of the Stock, the Company shall, as
expeditiously as reasonably possible:

            (a) Prepare and file with the SEC a Form S-3 with respect to such
Stock and use its best efforts to cause such registration statement to become
effective as soon as reasonably practicable after the mailing of the request for
such registration but in no event later than ninety (90) days after such
mailing. The Company shall keep such registration statement effective until the
earlier of (i) two (2) years after the Closing, (ii) the distribution of all of
the Stock as contemplated in the registration statement has been completed, and
(iii) the date which all shares of the Stock held by the Investor may
immediately be sold under Rule 144 during any 90-day period.

            (b) Prepare and file with the SEC such amendments and supplements to
such registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the
Act with respect to the disposition of all securities covered by such
registration statement.

            (c) Furnish to the Investor such numbers of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the
Act, and such other documents as the Investor may reasonably request in order to
facilitate the disposition of the Stock.

            (d) Use its best efforts to register and qualify the securities
covered by such registration statement under such other securities or Blue Sky
laws of such jurisdictions as shall be reasonably requested by the Investor;
provided that the Company shall not be required in connection therewith or as a
condition thereto to qualify to do business or to file a general consent to
service of process in any such states or jurisdictions.

                                      A-2
<PAGE>

            (e) Notify the Investor covered by such registration statement at
any time when a prospectus relating thereto is required to be delivered under
the Act of the happening of any event as a result of which the prospectus
included in such registration statement, as then in effect, includes an untrue
statement of a material fact or omits 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 then existing.

            (f) Cause all such Stock registered pursuant hereunder to be listed
on each securities exchange on which similar securities issued by the Company
are then listed.

            (g) Provide a transfer agent and registrar for all of the Stock
registered pursuant hereunder and a CUSIP number for all such Stock, in each
case not later than the effective date of such registration.

        1.4 Investor Obligation to Furnish Information. It shall be a condition
precedent to the obligations of the Company to take any action pursuant hereto
with respect to the Stock that the Investor shall furnish to the Company such
information regarding itself, the Stock, and the intended method of disposition
of such securities as shall be required to effect the registration of such
Stock.

        1.5 Expenses of Registration. All expenses incurred in connection with
registrations, filings or qualifications pursuant hereto, including (without
limitation) all registration, filing and qualification fees, printers' and
accounting fees, fees and disbursements of counsel for the Company (including
fees and disbursements of counsel for the Company in its capacity as counsel to
the Investor hereunder but excluding the fees and disbursements of any other
counsel for the Investor) shall be borne by the Company; provided, however, that
the Company shall not be required to pay for any expenses of any registration
proceeding begun pursuant hereto if the registration request is subsequently
withdrawn at the request of the Investor, unless the Investor agrees to forfeit
its right to any demand registration pursuant hereto; provided further, however,
that if at the time of such withdrawal, the Investor has learned of a material
adverse change in the condition, business, or prospects of the Company from that
known to the Investor at the time of its request and has withdrawn the request
with reasonable promptness following disclosure by the Company of such material
adverse change, then the Investor shall not be required to pay any of such
expenses and shall retain its right of registration pursuant to Section 1.2.

        1.6 Indemnification. In the event any Stock is included in a
registration statement under Section 1.2:

            (a) To the extent permitted by law, the Company will indemnify and
hold harmless the Investor, any underwriter (as defined in the Act) for the
Investor and each person, if any, who controls the Investor or underwriter
within the meaning of the Act or the 1934 Act, against any losses, claims,
damages, or liabilities (joint or several) to which they may become subject
under the Act, the 1934 Act or other federal or state law, insofar as such
losses, claims, damages, or liabilities (or actions in respect thereof) arise
out of or are based upon any of the following statements, omissions or
violations (collectively a "Violation"): (i) any untrue statement or alleged
untrue statement of a material fact contained in such registration statement,

                                      A-3
<PAGE>

including any preliminary prospectus or final prospectus contained therein or
any amendments or supplements thereto, (ii) the omission or alleged omission to
state therein a material fact required to be stated therein, or necessary to
make the statements therein not misleading, or (iii) any violation or alleged
violation by the Company of the Act, the 1934 Act, any state securities law or
any rule or regulation promulgated under the Act, the 1934 Act or any state
securities law; and the Company will pay to the Investor, or such underwriter or
controlling person, as incurred, any legal or other expenses reasonably incurred
by them in connection with investigating or defending any such loss, claim,
damage, liability, or action; provided, however, that the indemnity agreement
contained in this subsection (a) shall not apply to amounts paid in settlement
of any such loss, claim, damage, liability, or action if such settlement is
effected without the consent of the Company (which consent shall not be
unreasonably withheld), nor shall the Company be liable in any such case for any
such loss, claim, damage, liability, or action to the extent that it arises out
of or is based upon a Violation which occurs in reliance upon and in conformity
with written information furnished expressly for use in connection with such
registration by any such Investor, underwriter or controlling person.

            (b) To the extent permitted by law, the Investor will indemnify and
hold harmless the Company, each of its directors, each of its officers who has
signed the registration statement, each person, if any, who controls the Company
within the meaning of the Act, any underwriter, and any controlling person of
any such underwriter, against any losses, claims, damages, or liabilities (joint
or several) to which any of the foregoing persons may become subject, under the
Act, the 1934 Act or other federal or state law, insofar as such losses, claims,
damages, or liabilities (or actions in respect thereto) arise out of or are
based upon any Violation, in each case to the extent (and only to the extent)
that such Violation occurs in reliance upon and in conformity with written
information furnished by such Investor expressly for use in connection with such
registration; and each such Investor will pay, as incurred, any legal or other
expenses reasonably incurred by any person intended to be indemnified pursuant
to this subsection (b), in connection with investigating or defending any such
loss, claim, damage, liability, or action; provided, however, that the indemnity
agreement contained in this subsection (b) shall not apply to amounts paid in
settlement of any such loss, claim, damage, liability or action if such
settlement is effected without the consent of the Investor, which consent shall
not be unreasonably withheld; provided, that, in no event shall any indemnity
under this subsection (b) exceed the gross proceeds from the offering received
by the Investor.

            (c) Promptly after receipt by an indemnified party under this
Section 1.6 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying party under this Section 1.6, deliver to
the indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party
(together with all other indemnified parties which may be represented without
conflict by one counsel) shall have the right to retain one separate counsel,
with the fees and expenses to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential differing
interests between such indemnified party and any other party represented by such
counsel in such proceeding. The failure to deliver written notice to the
indemnifying party

                                      A-4
<PAGE>

within a reasonable time of the commencement of any such action, if prejudicial
to its ability to defend such action, shall relieve such indemnifying party of
any liability to the indemnified party under this Section 1.6, but the omission
so to deliver written notice to the indemnifying party will not relieve it of
any liability that it may have to any indemnified party otherwise than under
this Section 1.6.

            (d) If the indemnification provided for in this Section 1.6 is held
by a court of competent jurisdiction to be unavailable to an indemnified party
with respect to any loss, liability, claim, damage, or expense referred to
therein, then the indemnifying party, in lieu of indemnifying such indemnified
party hereunder, shall contribute to the amount paid or payable by such
indemnified party as a result of such loss, liability, claim, damage, or expense
in such proportion as is appropriate to reflect the relative fault of the
indemnifying party on the one hand and of the indemnified party on the other in
connection with the statements or omissions that resulted in such loss,
liability, claim, damage, or expense as well as any other relevant equitable
considerations. The relative fault of the indemnifying party and of the
indemnified party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission to state a material fact relates to information supplied by the
indemnifying party or by the indemnified party and the parties' relative intent,
knowledge, access to information, and opportunity to correct or prevent such
statement or omission.

            (e) Notwithstanding the foregoing, to the extent that the provisions
on indemnification and contribution contained in an underwriting agreement
entered into in connection with the underwritten public offering are in conflict
with the foregoing provisions, the provisions in the underwriting agreement
shall control.

            (f) The obligations of the Company and the Investor under this
Section 1.6 shall survive the completion of any offering of the Stock in a
registration statement pursuant hereto, and otherwise.

     1.7 Termination. The Company's obligation to register the Stock pursuant to
this agreement shall terminate on the earlier of (i) the second anniversary of
the Closing and (ii) the date on which all shares of the Stock held by the
Investor may immediately be sold under Rule 144 during any 90-day period.
