information about us, the ordinary shares that may be sold from time to time,
and our financial statements and the notes to them, all of which appear
elsewhere in this prospectus or in the documents incorporated by reference in

                        MER TELEMANAGEMENT SOLUTIONS LTD.

         We were incorporated under the laws of the State of Israel in December
1995 and are a public limited liability company under the Israeli Companies Law
5739-1999 and operate under such law and associated legislation. Our registered
offices and principal place of business are located at 22 Zarhin Street,
Ra'anana 43662, Israel, and our telephone number is 972-9-762-1777. Our
address on the Internet is www.mtsint.com. The information on our website is not
incorporated by reference into this prospectus.

         We are a total solutions provider in the telecom expense and billing
arenas. We design, develop, market and support a comprehensive line of
telecommunication management, expense management and customer care and billing,
or CC&B, solutions that enable business organizations and other enterprises to
more effectively manage and optimize the use of their communication resources.
Our products include call accounting and management products, fault management
systems and Web-based management solutions for converged voice, voice over IP,
or VoIP, IP data and video and CC&B solutions. These products are designed to
provide telecommunication and information technology managers with tools to
reduce communication costs, recover charges payable by third parties, detect and
report the abuse and misuse of telephone networks, monitor and detect hardware
and software faults in telecommunications networks and generate
telecommunications usage information for use in the management of an enterprise.
We were among the first to offer PC-based call accounting systems when we
introduced our TABS product in 1985. To date, over 60,000 TABS call accounting
systems have been sold to end-users in more than 60 countries. In addition,
approximately 1,000 WinTrak systems (which we acquired from IntegraTRAK, Inc. in
April 2000) have been sold in the United States market since 1985. Although we
are no longer marketing WinTRAK, we continue to support this product.

                                  RISK FACTORS

         You should carefully consider the risks and uncertainties described
below before investing in our ordinary shares. Our business, prospects,
financial condition and results of operations could be adversely affected due to
any of the following risks. In that case, the value of our ordinary shares could
decline, and you could lose all or part of your investment.

Risks Relating to Our Business and Market

We have had a recent history of operating  losses and may not achieve or sustain
profitability in the future.

         We have incurred operating losses in each of the five last fiscal years
and we cannot assure you that we will be able to achieve or sustain profitable
operations in the future. To the extent that we continue to incur operating
losses, we may not have sufficient working capital to fund our operations in the
future. If we do not generate sufficient cash from operations, we will be
required to obtain additional financing or reduce level of expenditure. There
can be no assurance that such financing will be available in the future, or, if
available, will be on terms satisfactory to us.

Our operating results fluctuate significantly.

         Our quarterly results have fluctuated significantly in the past and are
likely to fluctuate significantly in the future. Our future operating results
will depend on many factors, including, but not limited to the following:

          o    demand for our products;

          o    changes in our pricing policies or those of our competitors;

          o    the number, timing and significance of product enhancements;

          o    new product announcements by us and our competitors;

          o    our ability to  develop,  introduce  and market new and  enhanced
               products on a timely basis;

          o    changes in the level of our operating expenses;

          o    budgeting cycles of our customers;

          o    customer order  deferrals in  anticipation of enhancements or new
               products that we or our competitors offer;

          o    product life cycles;

          o    changes in our strategy;

                                        6





          o    seasonal trends and general domestic and  international  economic
               and political conditions, among others; and

          o    currency  exchange rate  fluctuations and economic  conditions in
               the geographic areas where we operate.

         Due to the foregoing factors, quarterly revenues and operating results
are difficult to forecast, and it is likely that our future operating results
will be adversely affected by these or other factors.

         Revenues are also difficult to forecast because the market for
telecommunication management solutions is rapidly evolving and our sales cycle,
from initial evaluation to purchase, is lengthy and varies substantially from
customer to customer. We typically ship product orders shortly after receipt of
a purchase order and, consequently, order backlog at the beginning of any
quarter has in the past represented only a small portion of that quarter's
revenues. As a result, license revenues in any quarter depend substantially on
orders booked and shipped in that quarter.

         Due to all of the foregoing, we cannot predict revenues for any future
quarter with any significant degree of accuracy. Accordingly, we believe that
period-to-period comparisons of our operating results are not necessarily
meaningful and you should not rely upon them as indications of future
performance. Although our revenues increased in 2004 and the first six months of
2005, our revenues declined in each of the years from 1999 to 2003 and we cannot
assure you that we will be able to sustain revenue growth in the future.

Our operating results vary quarterly and seasonally.

         We have often recognized a substantial portion of our revenues in the
last quarter of the year and in the last month, or even weeks or days, of a
quarter. Our expense levels are substantially based on our expectations for
future revenues and are therefore relatively fixed in the short term. If revenue
levels fall below expectations, our quarterly results are likely to be
disproportionately adversely affected because a proportionately smaller amount
of our expenses varies with our revenues.

         Our operating results are generally not characterized by a seasonal
pattern, except that our sales in Europe are generally lower in the summer
months. Due to the foregoing, in some future quarter, our operating results may
be below the expectations of public market analysts and investors. In such
event, it is likely that the price of our ordinary shares would be materially
and adversely affected.

We depend on the market for telemanagement  products,  which market has declined
in recent years.

         In recent years we have derived substantially all of our revenues from
our TABS.IT call accounting and billing products. We have implemented a new
strategy that has led to the development and introduction of our Application
Suite. The Application Suite is built on the Microsoft.Net platform and
establishes a framework for us to provide customized solutions that include
customer care and billing, in addition to the traditional telemanagement
solutions. The main functions of our TABS.IT and the WinTrak family of products
were incorporated into the

                                        7






Application Suite. Our future financial performance will depend, in significant
part, on the successful development, introduction, marketing and customer
acceptance of the Application Suite and related telemanagement products. Except
for a slight increase in revenues in the 2004 fiscal year and the increase in
revenues in the six months ended June 30, 2005, our revenues have declined each
year since 1999 and there can be no assurance that the market for these products
will grow in the future. If the market for the our telemanagement products fails
to return to previous levels, or grows more slowly than we currently anticipate,
our business, operating results and financial condition would be materially and
adversely affected.

We depend on business telephone system  manufacturers,  vendors and distributors
for our sales.

         One of the primary distribution channels for our call accounting
management products are private branch exchange, or PBX, original equipment
manufacturers, or OEMs, and vendors who market our products to end-users in
conjunction with their own products. We have entered into partnership agreements
with each of NEC and Avaya for the integration of our products with their own
products and the marketing of the integrated product. Sales by PBX manufacturers
and vendors have declined markedly in the recent past, and no assurance can be
given that sales through this channel will recover. Our success will be
dependent to a substantial degree on the marketing and sales efforts of such
third parties in marketing and integrating our products. There can be no
assurance that these third parties will give priority to the sale of our
products as an enhancement to their products. Although most of the major
business telephone switching systems manufacturers and vendors currently rely on
third-party suppliers to provide call accounting and other telemanagement
products, no assurance can be given that these manufacturers and vendors,
including our current customers, will not develop their own competing products
or purchase competing products from others.

         We are highly dependent upon the active marketing and distribution
efforts of our PBX OEM's. In 2002, 2003, 2004, and the six months ending June
30, 2005, our three major OEMs, Siemens Gmbh, Philips Communications Systems
B.V. and Ericsson, generated 46.0%, 51.0%, 47.0% and 39.0% of our consolidated
revenues, respectively. The percentage of sales attributable to each of these
OEMs in each of the three years ended December 31, 2004 and the six months
ending June 30, 2005 are as follows:

                                                             Six months
                                                               ended
                             2002        2003      2004    June 30, 2005
                             ----        ----      ----    -------------

Ericsson...............       4.0%        4.0%      4.0%        2.0%

         Because we sell our products through local master distributors in
countries where we do not have a marketing subsidiary, we are highly dependent
upon the active marketing and distribution efforts of our distributors. We also
depend in large part upon our distributors for product maintenance and support.
There can be no assurance that our distributors will continue to provide
adequate maintenance and support to end-users or will provide maintenance and
support for new products, which might cause us to seek new or additional
distributors or incur additional


                                       8






service and support costs. The distributors to whom we sell our products are
generally not contractually required to make future purchases of our products
and could, therefore, discontinue carrying our products at any time. None of our
distributors or resellers are subject to any minimum purchase requirements under
their agreements with us. There can be no assurance that we will continue our
relationships with our OEM customers or, if such relationships are not
maintained, that we would be able to attract and retain comparable PBX original
equipment manufacturers. The loss of any of our major reseller or OEM
relationships, either to competitive products offered by other companies or
products developed by such resellers, would have a material adverse effect on
our business, financial condition and results of operations. Our future
performance will depend, in part, on our ability to attract additional PBX
manufacturers and vendors that will be able to market and support our products
effectively, especially in markets in which we have not previously distributed
our products.

We have recently acquired certain assets of Teleknowledge  Group Ltd., and there
can be no assurance that we will successfully integrate their products.

         In December 2004, we completed the acquisition of certain assets and
liabilities of Teleknowledge Group Ltd., or Teleknowledge, a provider of carrier
class billing and related solutions. The acquisition of the Teleknowledge
billing solution enables us to offer an end-to-end customer care and billing
solution, including pre/post paid billing, Web self-care, assets management,
partner management, help desk and order management modules. These products offer
a complimentary solution to our own products. There can be no assurance that we
will successfully integrate the Teleknowledge products into our products.

We face  risks  associated  with  expanding  and  maintaining  our  distribution
network.

         We sell our products through distributors, business telephone switching
systems manufacturers and vendors, post, telephone and telegraph authorities, or
PTTs and our direct sales force. Our ability to achieve revenue growth in the
future will depend in large part on our success in establishing and maintaining
relationships with business telephone switching systems manufacturers and
vendors and PTTs, establishing and maintaining relationships with distributors,
and recruiting and training additional direct sales personnel. We plan to invest
significant resources to expand our direct sales force and to develop new
distribution relationships. Historically, we have at times experienced
difficulty in recruiting qualified sales personnel and in establishing effective
distribution relationships. There can be no assurance that we will be able to
successfully expand our direct sales force or other distribution channels or
that any such expansion will result in an increase in revenues. The failure to
expand or maintain our direct sales force or other distribution channels could
have a material adverse effect on our business, operating results and financial
condition.

We are subject to risks associated with international operations.

         We are based in Israel and generate a large percentage of our sales
outside the United States. Our sales in the United States accounted for 66.0%,
53.0%, 53.0% and 55.0% of our total revenues for the years ended December 31,
2002, 2003 and 2004, and the six months ended June 30, 2005, respectively.
Although we continue to expand our international operations and commit
significant management time and financial resources to developing direct and
indirect

                                       9






international sales and support channels, we cannot be certain that we will be
able to maintain or increase international market demand for our products. To
the extent that we cannot do so in a timely manner, our business, operating
results and financial condition will be materially and adversely affected.

         International operations are subject to inherent risks, including the
following:

          o    the impact of  possible  recessionary  environments  in  multiple
               foreign markets;

          o    costs of localizing products for foreign markets;

          o    longer  receivables  collection periods and greater difficulty in
               accounts receivable collection;

          o    unexpected changes in regulatory requirements;

          o    difficulties   and  costs  of  staffing  and   managing   foreign
               operations;

          o    reduced  protection  for  intellectual  property  rights  in some
               countries;

          o    potentially adverse tax consequences; and

          o    political and economic instability.

         We cannot be certain that we, our distributors or resellers will be
able to sustain or increase revenues from international operations or that the
foregoing factors will not have a material adverse effect on our future revenues
and, as a result, on our business, operating results and financial condition.

         We may be adversely affected by fluctuations in currency exchange
rates. While our revenues are generally denominated in U.S. dollars and Euros, a
significant portion of our expenses are incurred in NIS. We do not currently
engage in any currency hedging transactions intended to reduce the effect of
fluctuations in foreign currency exchange rates on our results of operations. If
we were to determine that it was in our best interests to enter into any hedging
transactions in the future, there can be no assurance that we will be able to do
so or that such transactions, if entered into, will materially reduce the effect
of fluctuations in foreign currency exchange rates on our results of operations.
In addition, if, for any reason, exchange or price controls or other
restrictions on the conversion of foreign currencies into NIS were imposed, our
business could be adversely affected. Although exposure to currency fluctuations
to date has not had a material adverse effect on our business, there can be no
assurance such fluctuations in the future will not have a material adverse
effect on revenues from international sales and, consequently, on our business,
operating results and financial condition.

We  are  subject  to  risks  relating  to   proprietary   rights  and  risks  of
infringement.

         We are dependent upon our proprietary software technology and we rely
primarily on a combination of copyright and trademark laws, trade secrets,
confidentiality procedures and contractual provisions to protect our proprietary
rights. We try to protect our software,

                                       10




documentation and other written materials under trade secret and copyright laws,
which afford only limited protection. It is possible that others will develop
technologies that are similar or superior to our technology. Despite our efforts
to protect our proprietary rights, unauthorized parties may attempt to copy
aspects of our products or to obtain and use information that we regard as
proprietary. It is difficult to police the unauthorized use of our products, and
we expect software piracy to be a persistent problem, although we are unable to
determine the extent to which piracy of our software products exists. In
addition, the laws of some foreign countries do not protect our proprietary
rights as fully as do the laws of the United States. We cannot be certain that
our means of protecting our proprietary rights in the United States or abroad
will be adequate or that our competition will not independently develop similar
technology.

         We are not aware that we are infringing upon any proprietary rights of
third parties. It is possible, however, that third parties will claim
infringement by us of their intellectual property rights. We believe that
software product developers will increasingly be subject to infringement claims
as the number of products and competitors in our industry segment grows and the
functionality of products in different industry segments overlaps. It would be
time consuming for us to defend any such claims, with or without merit, and any
such claims could:

          o    result in costly litigation;

          o    divert management's attention and resources;

          o    cause product shipment delays; or

          o    require us to enter into  royalty or licensing  agreements.  Such
               royalty  or  licensing  agreements,   if  required,  may  not  be
               available on terms acceptable to us, if at all.

         If there is a successful claim of product infringement against us and
we are not able to license the infringed or similar technology, our business,
operating results and financial condition would be materially and adversely
affected.

         We rely upon certain software that we license from third parties,
including software that we integrate with our internally developed software. We
cannot be certain that these third-party software licenses will continue to be
available to us on commercially reasonable terms. If we lose or are unable to
maintain any such software licenses, we could suffer shipment delays or
reductions until equivalent software could be developed, identified, licensed
and integrated, which would materially and adversely affect our business,
operating results and financial condition.

We may be unsuccessful in our defense of pending litigation.

         On April 18, 2005, Amdocs (Israel) Ltd. and Amdocs Ltd. filed a
complaint in the Tel Aviv District Court naming our company, our chief executive
officer and others as defendants (Civil File No. 32419-05/05). The complaint
alleges, among other things, that professional and commercial information
belonging to the plaintiffs was transferred to the defendants for use in our
company's activity. The plaintiffs are seeking an injunction prohibiting the
defendants from making any use of the information and trade secrets that were
allegedly transferred, and mandatory injunctions requiring the return of any
such information and the payment of estimated

                                       11






damages of NIS 14,775,000 (approximately US$3.3 million). On June 27, 2005, the
defendants filed a statement of defense, claiming that the factual and legal
allegations made by the plaintiffs have no basis, and the causes of action and
relief requested are without merit. Due to the preliminary stage of the
litigation proceeding, we cannot currently advise as to the outcome of the
lawsuit. We intend to vigorously defend this action, however, there can be no
assurance that we will be successful.

Our results may be adversely affected by competition.

         The market for telemanagement products is fragmented and is intensely
competitive. Competition in the industry is generally based on product
performance, depth of product line, technical support and price. We compete both
with international and local competitors (including providers of
telecommunications services), many of whom have significantly greater financial,
technical and marketing resources than us. We anticipate continuing competition
in the telemanagement products market and the entrance of new competitors into
the market. Our existing and potential customers, including business telephone
switching system manufacturers and vendors, may be able to develop
telemanagement products and services that are as effective as, or more effective
or easier to use than, those offered by us. Such existing and potential
competitors may also enjoy substantial advantages over us in terms of research
and development expertise, manufacturing efficiency, name recognition, sales and
marketing expertise and distribution channels. There can be no assurance that we
will be able to compete successfully against current or future competitors or
that competition will not have a material adverse effect on our future revenues
and, consequently, on our business, operating results and financial condition.

We are subject to risks  associated  with rapid  technological  change and risks
associated with new versions and new products.

         The telecommunications management market in which we compete is
characterized by rapid technological change, introductions of new products,
changes in customer demands and evolving industry standards. Our future success
will depend upon our ability to keep pace with the technological developments
and to timely address the increasingly sophisticated needs of our customers by
supporting existing and new telecommunication technologies and services and by
developing and introducing enhancements to our current and new products. There
can be no assurance that we will be successful in developing and marketing
enhancements to our products that will respond to technological change, evolving
industry standards or customer requirements, that we will not experience
difficulties that could delay or prevent the successful development,
introduction and sale of such enhancements or that such enhancements will
adequately meet the requirements of the marketplace and achieve any significant
degrees of market acceptance. If release dates of any new products or
enhancements are delayed or, if when released, they fail to achieve market
acceptance, our business, operating results and financial condition would be
materially and adversely affected. In addition, the introduction or announcement
of new product offerings or enhancements by us or our competitors may cause
customers to defer or forgo purchases of current versions of our product, which
could have a material adverse effect on our business, operating results and
financial condition.

                                       12






We may not be able to retain or attract key  managerial,  technical and research
and development personnel we need to succeed.

         Our success has largely depended and will depend in the future on our
skilled professional and technical employees, substantially all of whom have
written employment agreements. The competition for these employees is intense.
We may not be able to retain our present employees, or recruit additional
qualified employees as we require them.

Three of our  shareholders  are in a position  to control  matters  requiring  a
shareholder vote.

         Mr. Chaim Mer, our Chairman, and his wife, Dora Mer, our Israeli
counsel, currently control the vote of approximately 34.9% of our outstanding
ordinary shares, and Isaac Ben-Bassat, one of our directors, is the owner of
12.02% of our outstanding ordinary shares.

          As a result, such persons control and will continue to control the
election of our entire Board of Directors other than our two outside directors
and generally have the ability to direct our business and affairs.

We are subject to risks  arising  from  product  defects and  potential  product
liability.

         We provide free warranty and support for up to one year for end-users
and up to 15 months for our OEM distributors. Our sales agreements typically
contain provisions designed to limit our exposure to potential product liability
or related claims. The limitation of liability provisions contained in our
agreements may not be effective. Our products are used by businesses to reduce
communication costs, recover charges payable by third parties and prevent abuse
and misuse of telephone networks and, as a result, the sale of products by us
may entail the risk of product liability and related claims. A product liability
claim brought against us could have a material adverse effect upon our business,
operating results and financial condition. Products such as those offered by us
may contain undetected errors or failures when first introduced or when new
versions are released. Despite our testing and testing by current and potential
customers, there can be no assurance that errors will not be found in new
products or releases after commencement of commercial shipments. The occurrence
of these errors could result in adverse publicity, loss of or delay in market
acceptance or claims by customers against us, any of which could have a material
adverse effect upon our business, operating results and financial condition.

The  implementation  of  SFAS  No.  123(R),  which  will  require  us to  record
compensation  expense in connection  with equity share based  compensation as of
the first quarter of 2006, may reduce our profitability.

         On December 16, 2004, the Financial Accounting Standards Board, or
FASB, issued Statement No. 123 (revised 2004), Share-Based Payment, or SFAS No.
123(R), which is a revision of SFAS No. 123. Generally, the approach in SFAS No.
123(R) is similar to the approach described in SFAS No. 123. However, SFAS No.
123 permitted, but did not require, share-based payments to employees to be
recognized on the basis of their fair values while SFAS No. 123(R) requires, as
of the first quarter of 2006, all share-based payments to employees to be
recognized on the basis of their fair values. SFAS No. 123(R) also revises,
clarifies and expands guidance in several areas, including measuring fair value,
classifying an award as equity or as a liability and attributing compensation
cost to reporting periods. The adoption of SFAS No. 123(R) may have a

                                       13






significant effect on our results of operations in the future; however, the
impact of its adoption cannot be predicted at this time. In addition, such
adoption could limit our ability to use stock options as an incentive and
retention tool, which could, in turn, negatively impact our ability to recruit
employees and retain existing employees. However, had we adopted SFAS 123(R) in
prior periods, the impact of that standard would have approximated the impact of
SFAS No. 123 as described in the disclosure of pro forma net income and earnings
per share in our consolidated financial statements.

Risk Factors Related to Our Ordinary Shares

We are classified as a passive foreign investment  company,  or PFIC, which will
subject our U.S. investors to adverse tax rules.

         Holders of our ordinary shares who are United States residents face
income tax risks. There is a substantial risk that we are a passive foreign
investment company, commonly referred to as PFIC. Our treatment as a PFIC could
result in a reduction in the after-tax return to the holders of our ordinary
shares and would likely cause a reduction in the value of such shares. For U.S.
Federal income tax purposes, we will be classified as a PFIC for any taxable
year in which either (i) 75% or more of our gross income is passive income, or
(ii) at least 50% of the average value of all of our assets for the taxable year
produce or are held for the production of passive income. For this purpose, cash
is considered to be an asset, which produces passive income. As a result of our
relatively substantial cash position at the time, we believe that we became a
PFIC in 2004 under a literal application of the asset test described above,
which looks solely to the market value. If we are classified as a PFIC for U.S.
federal income tax purposes, highly complex rules would apply to U.S. Holders
owning ordinary shares. Accordingly, you are urged to consult your tax advisors
regarding the application of such rules.

Our share price has been volatile in the past and may decline in the future.

         Our ordinary shares have experienced significant market price and
volume fluctuations in the past and may experience significant market price and
volume fluctuations in the future in response to factors such as the following,
some of which are beyond our control:

          o    quarterly variations in our operating results;

          o    operating  results that vary from the  expectations of securities
               analysts and investors;

          o    changes in expectations as to our future  financial  performance,
               including   financial   estimates  by  securities   analysts  and
               investors;

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

          o    announcements by us or our competitors of significant  contracts,
               acquisitions,  strategic partnerships,  joint ventures or capital
               commitments;

          o    changes in the status of our intellectual property rights;

                                       14






          o    announcements   by  third  parties  of   significant   claims  or
               proceedings against us;

          o    additions or departures of key personnel;

          o    future sales of our ordinary shares; and

          o    general stock market prices and volume fluctuations.

         Domestic and international stock markets often experience extreme price
and volume fluctuations. Market fluctuations, as well as general political and
economic conditions, such as a recession or interest rate or currency rate
fluctuations or political events or hostilities in or surrounding Israel, could
adversely affect the market price of our ordinary shares.

         In the past, securities class action litigation has often been brought
against a company following periods of volatility in the market price of its
securities. We may in the future be the target of similar litigation. Securities
litigation could result in substantial costs and divert management's attention
and resources.

We do not expect to distribute cash dividends.

         We do not anticipate paying cash dividends in the foreseeable future.
Our Board of Directors will decide whether to declare any cash dividends in the
future based on the conditions then existing, including our earnings and
financial condition. According to the Israeli Companies Law, a company may
distribute dividends out of its profits (within the meaning of the Israeli
Companies Law), so long as the company reasonably believes that such dividend
distribution will not prevent the company from paying all its current and future
debts.

Compliance  with  changing   regulation  of  corporate   governance  and  public
disclosure may result in additional expenses.

         Changing laws, regulations and standards relating to corporate
governance and public disclosure, including the Sarbanes-Oxley Act of 2002, new
Securities and Exchange Commission regulations and NASDAQ Stock Market rules,
are creating uncertainty for companies such as ours. We are committed to
maintaining high standards of corporate governance and public disclosure. As a
result, we intend to invest reasonably necessary resources to comply with
evolving standards, and this investment may result in increased general and
administrative expenses and a diversion of management time and attention from
revenue-generating activities to compliance activities, which could harm our
operating results and business prospects.

Risks Relating to Operations in Israel

Conducting business in Israel entails special risks.

         We are incorporated under the laws of, and our executive offices and
research and development facilities are located in, the State of Israel.
Although most of our sales are made to customers outside Israel, we are directly
influenced by the political, economic and military conditions affecting Israel.
Specifically, we could be adversely affected by any major hostilities involving
Israel, a full or partial mobilization of the reserve forces of the Israeli
army, the

                                       15




interruption or curtailment of trade between Israel and its present trading
partners, or a significant downturn in the economic or financial condition of
Israel.

         Since the establishment of the State of Israel in 1948, a number of
armed conflicts have taken place between Israel and its Arab neighbors, and a
state of hostility, varying from time to time in intensity and degree, has led
to security and economic problems for Israel. Since September 2000, there has
been a marked increase in violence, civil unrest and hostility, including armed
clashes, between the State of Israel and the Palestinians, and acts of terror
have been committed inside Israel and against Israeli targets in the West Bank
and Gaza. These developments have adversely affected the regional peace process,
placed the Israeli economy under significant stress, and have negatively
influenced Israel's relationship with several Arab countries. In August 2005,
Israel evacuated all Israeli settlements in the Gaza Strip and four settlements
in the West Bank. The implications of this action cannot at this time be
foreseen. Any future armed conflict, political instability or violence in the
region may have a negative effect on our business condition, harm our results of
operations and adversely affect our share price.

         Furthermore, there are a number of countries that restrict business
with Israel or Israeli companies. Restrictive laws or policies of those
countries directed towards Israel or Israeli businesses had, and may in the
future continue to have, an adverse impact on our operations, our financial
results or the expansion of our business. No predictions can be made as to
whether or when a final resolution of the area's problems will be achieved or
the nature thereof and to what extent the situation will impact Israel's
economic development or our operations.

Political   trade   relations   could   limit  our   ability   to  sell  or  buy
internationally.

         We could be adversely affected by the interruption or reduction of
trade between Israel and its trading partners. Some countries, companies and
organizations continue to participate in a boycott of Israeli firms and others
doing business with Israel or with Israeli companies. To date, these measures
have not had a material adverse affect on our business. However, there can be no
assurance that restrictive laws, policies or practices towards Israel or Israeli
businesses will not have an adverse impact on our business.

Our results of operations  may be negatively  affected by the  obligation of our
personnel to perform military service.

         Many of our directors, officers and employees in Israel are obligated
to perform annual reserve duty in the Israeli Defense Forces and may be called
for active duty under emergency circumstances at any time. If a military
conflict or war arises, these individuals could be required to serve in the
military for extended periods of time. Our operations could be disrupted by the
absence for a significant period of one or more of our executive officers or key
employees or a significant number of other employees due to military service.
Any disruption in our operations could adversely affect our business.

The economic conditions in Israel have not been stable in recent years.

         In recent years Israel has been going through a period of recession in
economic activity, resulting in low growth rates and growing unemployment.
Although economic activity in Israel has improved recently, our operations could
be adversely affected if the economic conditions in

                                       16




Israel begin to deteriorate once again. In addition, due to significant economic
measures proposed by the Israeli Government, there have been several general
strikes and work stoppages in 2003 and 2004, affecting all banks, airports and
ports. These strikes have had an adverse effect on the Israeli economy and on
business, including our ability to deliver products to our customers.

Our  financial  results may be  adversely  affected by  inflation  and  currency
fluctuations.

         Since we report our financial results in dollars, fluctuations in rates
of exchange between the dollar and non-dollar currencies may affect our results
of operations. The majority of our expenses are paid in NIS (primarily salaries)
and are influenced by the timing of, and the extent to which, any increase in
the rate of inflation in Israel over the rate of inflation in the United States
is not offset by the devaluation of the NIS in relation to the dollar. We
believe that the rate of inflation in Israel has not had a material adverse
effect on our business to date. However, our dollar costs in Israel will
increase if inflation in Israel exceeds the devaluation of the NIS against the
dollar or if the timing of such devaluation lags behind inflation in Israel.
Over time, the NIS has been devalued against the dollar, generally reflecting
inflation rate differentials. We cannot predict any future trends in the rate of
inflation in Israel or the rate of devaluation of the NIS against the dollar. If
the dollar cost of our operations in Israel increases, our dollar measured
results of operations will be adversely affected. Likewise, our operations could
be adversely affected if we are unable to guard against currency fluctuations in
the future.

The government programs and tax benefits we currently  participate in or receive
require us to meet several  conditions  and may be  terminated or reduced in the
future.

         We have benefited from certain Israeli Government grants, programs and
tax benefits. To remain eligible for these grants, programs and tax benefits, we
must comply with certain conditions, including making specified investments in
fixed assets from our own equity and paying royalties with respect to grants
received. In addition, some of these programs restrict our ability to
manufacture particular products and to transfer particular technology outside of
Israel. If we do not meet these conditions in the future, the benefits we
received could be canceled and we may have to refund payments previously
received under these programs or pay increased taxes. The Government of Israel
has reduced the benefits available under these programs in recent years and
these programs and tax benefits may be discontinued or curtailed in the future.
We intend to apply to the Office of the Chief Scientist for grants in the second
half of 2005 and in 2006; however, there can be no assurance that we will be
able to obtain any such grants in the future.

Service and  enforcement  of legal  process on us and our directors and officers
may be difficult to obtain.

         Service of process upon our directors and officers and the Israeli
experts named herein, most of whom reside outside the United States, may be
difficult to obtain within the United States. Furthermore, since substantially
all of our assets, most of our directors and officers and the Israeli experts
named herein are located outside the United States, any judgment obtained in the
United States against us or these individuals or entities may not be collectible
within the United States.

         There is doubt as to the enforceability of civil liabilities under the
Securities Act and the Securities Exchange Act in original actions instituted in
Israel. However, subject to certain time

                                       17






limitations and other conditions, Israeli courts may enforce final judgments of
United States courts for liquidated amounts in civil matters, including
judgments based upon the civil liability provisions of those Acts.

Provisions of Israeli law may delay, prevent or make difficult an acquisition of
us, which could prevent a change of control and  therefore  depress the price of
our shares.

         Provisions of Israeli corporate and tax law may have the effect of
delaying, preventing or making more difficult a merger with, or other
acquisition of, us. This could cause our ordinary shares to trade at prices
below the price for which third parties might be willing to pay to gain control
of us. Third parties who are otherwise willing to pay a premium over prevailing
market prices to gain control of us may be unable or unwilling to do so because
of these provisions of Israeli law.

The rights and  responsibilities of our shareholders are governed by Israeli law
and differ in some respects from the rights and responsibilities of shareholders
under U.S. law.

We are incorporated under Israeli law. The rights and responsibilities of
holders of our ordinary shares are governed by our memorandum of association,
articles of association and by Israeli law. These rights and responsibilities
differ in some respects from the rights and responsibilities of shareholders in
typical U.S. corporations. In particular, each shareholder of an Israeli company
has a duty to act in good faith in exercising his or her rights and fulfilling
his or her obligations toward the company and other shareholders and to refrain
from abusing his power in the company, including, among other things, in voting
at the general meeting of shareholders on certain matters. Israeli law provides
that these duties are applicable in shareholder votes on, among other things,
amendments to a company's articles of association, increases in a company's
authorized share capital, mergers and interested party transactions requiring
shareholder approval. In addition, a controlling shareholder of an Israeli
company or a shareholder who knows that it possesses the power to determine the
outcome of a shareholder vote or who has the power to appoint or prevent the
appointment of a director or officer in the company has a duty of fairness
toward the company. However, Israeli law does not define the substance of this
duty of fairness. Because Israeli corporate law has undergone extensive revision
in recent years, there is little case law available to assist in understanding
the implications of these provisions that govern shareholder behavior.

                              SELLING SHAREHOLDERS

         The registration statement of which this prospectus forms a part covers
up to 1,349,500 ordinary shares. Of such shares, 937,500 shares were issued to
certain of the selling shareholders, and 375,000 shares are issuable upon the
exercise of warrants that were issued to them, pursuant to a Securities Purchase
Agreement dated August 10, 2005. Such warrants have an exercise price of US$4.00
per share, subject to anti-dilution adjustments, and are exercisable from
February 10, 2006 until August 10, 2009. The ordinary shares and warrants were
offered and sold to the selling shareholders in reliance upon the exemption from
securities registration afforded by the provisions of Regulation D promulgated
under the Securities Act of 1933, as amended. The selling shareholders, other
than our President, Mr. Eytan Bar, paid $3.00 per share for the ordinary shares
purchased in the private placement. Mr. Bar purchased 14,000 shares at $3.88 per
share, the closing price of our ordinary shares on the day prior to the closing
of the private placement. We also undertook to effect the registration of the
ordinary shares issued and the ordinary shares issuable upon exercise of the
warrants and to maintain a registration statement in effect in order to allow
the selling shareholders to dispose of these shares from time to time. An
additional 37,000 ordinary shares are issuable pursuant to a warrant issued to
Mr. Avraham Ziv on August 3, 2005 in connection with financial services that he
has provided to our company. These warrants have an exercise price of $4.00 per
share, subject to anti-dilution adjustments, and are exercisable from February
3, 2006 until August 3, 2009. Mr. Ziv has provided financial services to us from
to time during the last five years. Except for the ownership of the ordinary
shares and the warrants, the selling shareholders, other than Messrs. Eytan Bar
and Avraham Ziv and our investment in the employee severance fund managed by
Apex - Provident Funds Management Ltd., have not had any material relationship
with us within the past three years.

         The table below lists the selling shareholders and other information
regarding the beneficial ownership of the ordinary shares by each of the selling
shareholders. The first column lists each of the selling shareholders. The
second and third column list the number and percentage of ordinary shares
beneficially owned by each selling shareholder prior to the offering, based on
each selling shareholder's ownership of the ordinary shares and the warrants, as
of August 10, 2005, assuming full exercise of the warrants held by each selling
shareholder on that date, without regard to any limitations on exercise. The
fourth column lists the ordinary shares being offered by this prospectus by each
of the selling shareholders.

         In accordance with the terms of a registration rights agreement with
the selling shareholders, other than Mr. Ziv, this prospectus generally covers
ordinary shares in an amount equal to the number of ordinary shares issued to
the selling shareholders and issuable upon exercise of the related warrants,
determined as if the outstanding warrants were exercised in full as

                                       20




of the trading day immediately preceding the date this registration statement
was initially filed with the Securities and Exchange Commission. Because the
exercise price of the warrants may be adjusted, the number of shares that will
actually be issued may be more or less than the number of shares being offered
by this prospectus.

         The fifth and sixth columns of the following table assume the sale of
all of the ordinary shares offered by each selling shareholder pursuant to this
prospectus.


                                                                                                            Percentage of

         OFFER STATISTICS, EXPECTED TIME TABLE AND PLAN OF DISTRIBUTION

         We are registering the ordinary shares issued to the selling
shareholders and issuable upon exercise of the warrants to permit the resale of
these ordinary shares by the holders of the ordinary shares and the warrants
from time to time after the date of this prospectus. We will not receive any of
the proceeds from the sale by the selling shareholders of the ordinary shares.
We will bear all fees and expenses incident to our obligation to register the
ordinary shares.

                                       23





         The selling shareholders may sell all or a portion of the ordinary
shares beneficially owned by them and offered hereby from time to time directly
or through one or more underwriters, broker-dealers or agents. If the ordinary
shares are sold through underwriters or broker-dealers, the selling shareholders
will be responsible for underwriting discounts or commissions or agent's
commissions. The ordinary shares may be sold in one or more transactions at
fixed prices, at prevailing market prices at the time of the sale, at varying
prices determined at the time of sale, or at negotiated prices. These sales may
be effected in transactions, which may involve crosses or block transactions, on
any national securities exchange or quotation service on which the securities
may be listed or quoted at the time of sale; in the over-the-counter market; in
transactions otherwise than on these exchanges or systems or in the
over-the-counter market; through the writing of options, whether such options
are listed on an options exchange or otherwise; ordinary brokerage transactions
and transactions in which the broker-dealer solicits purchasers; block trades in
which the broker-dealer will attempt to sell the shares as agent but may
position and resell a portion of the block as principal to facilitate the
transaction; purchases by a broker-dealer as principal and resale by the
broker-dealer for its account; an exchange distribution in accordance with the
rules of the applicable exchange; privately negotiated transactions; short
sales. Broker-dealers may agree with the selling security holders to sell a
specified number of such shares at a stipulated price per share; a combination
of any such methods of sale; and any other method permitted pursuant to
applicable law.

         If the selling shareholders effect such transactions by selling
ordinary shares to or through underwriters, broker-dealers or agents, such
underwriters, broker-dealers or agents may receive commissions in the form of
discounts, concessions or commissions from the selling shareholders or
commissions from purchasers of the ordinary shares for whom they may act as
agent or to whom they may sell as principal (which discounts, concessions or
commissions as to particular underwriters, broker-dealers or agents may be in
excess of those customary in the types of transactions involved). In connection
with sales of the ordinary shares or otherwise, the selling shareholders may
enter into hedging transactions with broker-dealers, which may in turn engage in
short sales of the ordinary shares in the course of hedging in positions they
assume. The selling shareholders may also sell ordinary shares short and deliver
ordinary shares covered by this prospectus to close out short positions. The
selling shareholders may also loan or pledge ordinary shares to broker-dealers
that in turn may sell such shares.

         The selling shareholders may pledge or grant a security interest in
some or all of the warrants or ordinary shares owned by them and, if they
default in the performance of their secured obligations, the pledgees or secured
parties may offer and sell the ordinary shares from time to time pursuant to
this prospectus or any amendment to this prospectus under Rule 424(b)(3) or
other applicable provision of the Securities Act of 1933, as amended, amending,
if necessary, the list of selling shareholders to include the pledgee,
transferee or other successors in interest as selling shareholders under this
prospectus. The selling shareholders also may transfer and donate the ordinary
shares in other circumstances in which case the transferees, donees, pledgees or
other successors in interest will be the selling beneficial owners for purposes
of this prospectus.

         The selling shareholders and any broker-dealer participating in the
distribution of the ordinary shares may be deemed to be "underwriters" within
the meaning of the Securities Act, and any commission paid, or any discounts or
concessions allowed to, any such broker-dealer may be

                                       24





deemed to be underwriting commissions or discounts under the Securities Act. At
the time a particular offering of the ordinary shares is made, a prospectus
supplement, if required, will be distributed which will set forth the aggregate
amount of ordinary shares being offered and the terms of the offering, including
the name or names of any broker-dealers or agents, any discounts, commissions
and other terms constituting compensation from the selling shareholders and any
discounts, commissions or concessions allowed or re-allowed or paid to
broker-dealers.

         Under the securities laws of some states, the ordinary shares may be
sold in such states only through registered or licensed brokers or dealers. In
addition, in some states the ordinary shares may not be sold unless such shares
have been registered or qualified for sale in such state or an exemption from
registration or qualification is available and is complied with.

         There can be no assurance that any selling shareholder will sell any or
all of the ordinary shares registered pursuant to the registration statement, of
which this prospectus forms a part.

         The selling shareholders and any other person participating in such
distribution will be subject to applicable provisions of the Securities Exchange
Act of 1934, as amended, and the rules and regulations thereunder, including,
without limitation, Regulation M of the Exchange Act, which may limit the timing
of purchases and sales of any of the ordinary shares by the selling shareholders
and any other participating person. Regulation M may also restrict the ability
of any person engaged in the distribution of the ordinary shares to engage in
market-making activities with respect to the ordinary shares. All of the
foregoing may affect the marketability of the ordinary shares and the ability of
any person or entity to engage in market-making activities with respect to the
ordinary shares.

         We will pay all expenses of the registration of the ordinary shares
pursuant to the registration rights agreement, including, without limitation,
Securities and Exchange Commission filing fees and expenses of compliance with
state securities or "blue sky" laws; provided, however, that a selling
shareholder will pay all underwriting discounts and selling commissions, if any.
We will indemnify the selling shareholders against liabilities, including some
liabilities under the Securities Act, in accordance with the registration rights
agreement, or the selling shareholders will be entitled to contribution. We may
be indemnified by the selling shareholders against civil liabilities, including
liabilities under the Securities Act, that may arise from any written
information furnished to us by the selling shareholder specifically for use in
this prospectus, in accordance with the related registration rights agreement,
or we may be entitled to contribution.

         Once sold under the registration statement, of which this prospectus
forms a part, the ordinary shares will be freely tradable in the hands of
persons other than our affiliates.

                    EXPENSES ASSOCIATED WITH THE REGISTRATION

         We have agreed to bear all expenses relating to the registration of the
ordinary shares registered pursuant to the registration statement of which this
prospectus is a part. We estimate these expenses to be approximately $52,000,
which include the following categories of expenses:

                                       25





         SEC registration fee.....................................      $ 595.64
         Printing, Edgar and photocopying fees ...................      3,000.00
         Legal fees and expenses..................................     25,000.00
         Accounting fees and expenses.............................     22,000.00
         Transfer agent and registrar fees and expenses...........      1,000.00
         Miscellaneous expenses                                           404.36
                  Total Expenses..................................   $ 52,000.00


                 FOREIGN EXCHANGE CONTROLS AND OTHER LIMITATIONS

         Non-residents of Israel who purchase our ordinary shares may freely
convert all amounts received in Israeli currency in respect of such ordinary
shares, whether as a dividend, as a liquidating distribution or as proceeds from
the sale of the ordinary shares, into freely-repatriable non-Israeli currencies
at the rate of exchange prevailing at the time of conversion (provided in each
case that the applicable Israeli income tax, if any, is paid or withheld).
Israeli residents are also eligible to purchase ordinary shares.

         Until May 1998, Israel imposed extensive restrictions on transactions
in foreign currency. These restrictions were largely lifted in May 1998. Since
January 1, 2003, all exchange control restrictions have been eliminated
(although there are still reporting requirements for foreign currency
transactions). Legislation remains in effect, however, pursuant to which
currency controls can be imposed by administrative action at any time.

         The State of Israel does not restrict in any way the ownership or
voting of ordinary shares by non-residents of Israel, except with respect to
subjects of countries that are in a state of war with Israel.

Commission, or the SEC, under the Securities Act of 1933. As permitted by the

         We are an Israeli company and are a "foreign private issuer" as defined
in Rule 3b-4 under the Securities Exchange Act of 1934. As a result, (1) our
proxy solicitations are not subject to the disclosure and procedural
requirements of Regulation 14A under the Exchange Act, (2) transactions in our
equity securities by our officers and directors are exempt from Section 16 of
the Exchange Act, and (3) until November 4, 2002, we were not required to make,
and did not make, our SEC filings electronically, so that those filings are not
available on the SEC's Web site. However, since that date, we have been making
all required filings with the SEC electronically, and these filings are
available over the Internet at the SEC's Web site at http: // www.sec.gov.

                       ENFORCEABILITY OF CIVIL LIABILITIES

         Service of process upon us and upon our directors and officers and the
Israeli experts named in this prospectus, most of whom reside outside the United
States, may be difficult to obtain within the United States. Furthermore,
because substantially all of our assets and substantially all of our directors
and officers are located outside the United States, any judgment obtained in the
United States against us or any of our directors and officers may not be
collectible within the United States.

         We have been informed by our legal counsel in Israel , M. Seligman &
Co., that there is doubt as to the enforceability of civil liabilities under the
Securities Act and the Exchange Act in

                                       28






original actions instituted in Israel. However, subject to specified time
limitations, an Israeli court may declare a foreign civil judgment enforceable
if it finds that:

          o    the judgment was rendered by a court which was,  according to the
               laws of the state of the court, competent to render the judgment,

          o    the judgment is no longer appealable,

          o    the obligation  imposed by the judgment is enforceable  according
               to the rules  relating  to the  enforceability  of  judgments  in
               Israel and the  substance  of the  judgment  is not  contrary  to
               public policy, and

          o    the judgment is executory in the state in which it was given.

         Even if the above conditions are satisfied, an Israeli court will not
enforce a foreign judgment if it was given in a state whose laws do not provide
for the enforcement of judgments of Israeli courts (subject to exceptional
cases) or if its enforcement is likely to prejudice the sovereignty or security
of the State of Israel.

         An Israeli court also will not declare a foreign judgment enforceable
if:

          o    the judgment was obtained by fraud,

          o    there was no due process,

          o    the judgment  was rendered by a court not  competent to render it
               according to the laws of private international law in Israel,

          o    the judgment is at variance with another  judgment that was given
               in the same matter  between  the same  parties and which is still
               valid, or

          o    at the time the action was brought in the foreign court a suit in
               the same matter and between the same parties was pending before a
               court or tribunal in Israel.

         We have irrevocably appointed MTS IntegraTRAK, Inc. as our agent to
receive service of process in any action against us in the state and federal
courts sitting in the City of New York, Borough of Manhattan arising out of this
offering or any purchase or sale of securities in connection therewith. We have
not given consent for this agent to accept service of process in connection with
any other claim.

         If a foreign judgment is enforced by an Israeli court, it generally
will be payable in Israeli currency. Judgment creditors must bear the risk of
unfavorable exchange rates.

                                     PART II
                     INFORMATION NOT REQUIRED IN PROSPECTUS

Item 8. Indemnification of Directors and Officers

         Israeli law provides that a company may, if permitted by its articles
of association, enter into a contract to insure office holders in respect of
liabilities incurred by the office holder with a respect to an act performed in
his or her capacity as an office holder, as a result of the breach of his or her
duty of care to the company or to another person, or as a result of the breach
of his or her duty of loyalty to the company, provided that the office holder
acted in good faith and had reasonable cause to believe that the act would not
prejudice the company. A company can also insure an office holder for monetary
liabilities as a result of an act or omission that the office holder committed
in connection with his or her serving as an office holder.

         In addition, under Israeli law a company may, if permitted by its
articles of association, indemnify an office holder for (a) monetary liability
imposed upon the office holder in favor of other persons pursuant to a court
judgment, including a settlement or an arbitrator's decision approved by a
court; (b) reasonable litigation expenses, including attorney's fees, actually
incurred by the office holder as a result of an investigation or proceeding
instituted against him by a competent authority, provided that such
investigation or proceeding concluded without the filing of an indictment
against him or the imposition of any financial liability in lieu of criminal
proceedings, or concluded without the filing of an indictment against him and a
financial liability was imposed on him in lieu of criminal proceedings with
respect to a criminal offense that does not require proof of criminal intent;
and (c) reasonable litigation expenses, including attorneys' fees, actually
incurred by the office holder or imposed upon the office holder by a court: (i)
in an action, suit or proceeding brought against the office holder by or on
behalf of the company or other persons, (ii) in connection with a criminal
action in which the office holder was acquitted, or (iii) in connection with a
criminal action in which the office holder was convicted which does not require
proof of criminal intent; in each case in connection with his or her activities
as an office holder.

         Israeli law provides that a company's articles of association may
permit the company to (a) indemnify an office holder following a determination
to this effect made by the company after the occurrence of the event in respect
of which the office holder will be indemnified; and (b) undertake in advance to
indemnify an office holder, provided that the undertaking is limited to types of
occurrences, which, in the opinion of the company's board of directors, are, at
the time of the undertaking, foreseeable due to the company's activities and to
an amount or standard that the board of directors has determined is reasonable
under the circumstances.

         Israeli law also allows a company, if permitted by its articles of
association, to exculpate an office holder in advance, in whole or in part, from
liability for damages sustained by a breach of duty of care to the company.
However, a company may not exculpate a director in advance from his liability to
the company with respect to a breach of his duty of care in the event of
distributions.

         These provisions are specifically limited in their scope by Israeli
law, which provides that a company may not indemnify an office holder, nor
exculpate an office holder, nor enter into an

                                      II-1






insurance contract which would provide coverage for any monetary liability,
incurred as a result of certain improper actions.

         The term "office holder" of a company includes any person who, either
formally or in substance, serves as a director, general manager or chief
executive officer, or other executive officer who reports directly to the
general manager or chief executive officer of a company.

         Our Articles of Association allow us to insure, indemnify and exempt
our office holders to the fullest extent permitted by law, subject to the
provisions of the Israeli Companies Law. We maintain a directors' and officers'
liability insurance policy with a per claim and aggregate coverage limit of $5
million, including legal costs incurred in Israel. In addition, our Audit
Committee, Board of Directors and shareholders resolved to indemnify our office
holders, pursuant to a standard indemnification agreement that provides for
indemnification of an office holder in an amount up to $3 million.

         Pursuant to the terms under which the ordinary shares were issued to
the selling shareholder, we agreed to indemnify the selling shareholders against
such liabilities as it may incur as a result of any untrue statement or alleged
untrue statement of a material fact in the registration statement or prospectus,
or any omission to state therein a material fact required to be stated therein
or necessary in order to make the statements made, in light of the circumstances
under which they were made, not misleading. Such indemnification includes
liabilities under the Securities Act, the Exchange Act, state securities laws
and the rules thereunder, but excludes liabilities for statements or omissions
that were based on information provided by the selling shareholder, as to which
the selling shareholder has agreed to indemnify us.

Item 10.  Undertakings

         The undersigned Registrant hereby undertakes:

         (1) To file, during any period in which offers or sales are being made,
a post-effective amendment to this registration statement:

               (i)  To include any  prospectus  required by Section  10(a)(3) of
                    the Securities Act of 1933;

               (ii) To reflect  in the  prospectus  any facts or events  arising
                    after the effective date of the  registration  statement (or
                    the most recent  post-effective  amendment  thereof)  which,
                    individually  or in the  aggregate,  represent a fundamental
                    change  in the  information  set  forth in the  registration
                    statement.  Notwithstanding  the foregoing,  any increase or
                    decrease  in  volume  of  securities  offered  (if the total
                    dollar  value of  securities  offered  would not exceed that
                    which was registered) and any deviation from the low or high
                    end of the estimated maximum offering range may be reflected
                    in the form of prospectus filed with the Commission pursuant
                    to Rule 424(b) if, in the  aggregate,  the changes in volume
                    and price  represent  no more than 20 percent  change in the
                    maximum   aggregate   offering   price   set  forth  in  the
                    "Calculation  of  Registration  Fee" table in the  effective
                    registration statement; and

               (iii) To include any  material  information  with  respect to the
                    plan  of  distribution  not  previously   disclosed  in  the
                    registration  statement  or  any  material  change  to  such
                    information in the registration statement.

              Provided, however, That paragraphs (1)(i) and (1)(ii) do not apply
              if the information required to be included in a post-effective
              amendment by those paragraphs is contained in periodic reports
              filed with or furnished to the Commission by the Registrant
              pursuant to Section 13 or 15(d) of the Securities Exchange Act of
              1934 that are incorporated by reference in the registration
              statement.

         (2) That, for the purpose of determining liability under the Securities
Act of 1933, each such post-effective amendment 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 bone
fide offering thereof.

         (3) To remove from registration by means of a post-effective amendment
any of the securities being registered which remain unsold at the termination of
the offering.

         (4) To file a post-effective amendment to the registration statement to
include any financial statements required by Item 8.A. of Form 20-F at the start
of any delayed offering or throughout a continuous offering. Financial
statements and information otherwise required by Section 10(a)(3) of the Act
need not be furnished, provided that the Registrant includes in the prospectus,
by means of a post-effective amendment, financial statements required pursuant
to

                                      II-4






this paragraph and other information necessary to ensure that all other
information in the prospectus is at least as current as the date of those
financial statements. Notwithstanding the foregoing, with respect to
registration statements on Form F-3, a post-effective amendment need not be
filed to include financial statements and information required by Section
10(a)(3) of the Act or Rule 3-19 of Regulation S-K if such financial statements
and information are contained in periodic reports filed with or furnished to the
Commission by the Registrant pursuant to Section 13 or 15(d) of the Securities
Exchange Act of 1934 that are incorporated by reference in the Form F-3.

         (5) That, for the purposes of determining liability under the
Securities Act of 1933, each filing of the Company's annual report pursuant to
Section 13(a) or Section 15(d) of the Exchange Act of 1934 (and, where
applicable, each filing of an employee benefit plan's annual report pursuant to
Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by
reference in this registration statement 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 thereof.

         (6) Insofar as indemnification for liabilities arising under the
Securities Act, may be permitted to directors, officers and controlling persons
of the Company, pursuant to the foregoing provisions, or otherwise, the Company
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 Securities Act and will be governed by the final
adjudication of such issue.

                                      II-5







                                   SIGNATURES

         Pursuant to the requirements of the Securities Act, the Registrant
certifies that it has reasonable grounds to believe that it complies with all of
the requirements for filing on Form F-3 and has duly caused this amendment to
its registration statement to be signed on its behalf by the undersigned,
thereunto duly authorized, in Ra'anana, Israel, on September 9, 2005.
