                                   THE COMPANY

         New Era of Networks, Inc. ("NEON") develops, markets and supports
enterprise application integration ("EAI") software and services. Our
architectural platform provides organizations with a structured software
platform for the rapid and efficient integration and ongoing maintenance of
disparate systems and applications across the enterprise. Our packaged software
solutions support EAI across popular hardware platforms, operating systems, and
database types. NEON has four product offerings: MQSeries Integrator, NEON
Integration Adapters, NEON Integration Options and NEON Integration
Applications.

RECENT EVENTS

         Second Quarter Results. On July 20, 1999, we announced that our
second-quarter revenues were $26.1 million, compared to revenues of $11.5
million for the same period last year. We reported a per-share loss of 28 cents,
compared to a loss of 11 cents for the second quarter of 1998. Excluding
acquisition-related charges and amortization, our loss for the quarter, net of
tax effect, was 19 cents, compared to earnings of 5 cents in the second quarter
of 1998. After our July 6, 1999 announcement of anticipated second-quarter
results, several lawsuits alleging violation of federal securities laws have
been filed against the Company and various officers. The Company believes that
these lawsuits are without merit, and we will respond appropriately.

         Acquisitions. We announced in April the acquisition of VIE Systems, a
privately held EAI company with a strong presence in travel and transportation,
financial services and retail markets. Also in April, we announced the
acquisition of SLI International AG, a worldwide provider of SAP R/3
implementation, training, support and business consulting services. In June, we
announced the acquisitions of Convoy Corporation and MicroScript Inc. Convoy
Corporation is a worldwide provider of application integration software and
professional services for PeopleSoft applications. MicroScript Inc. is the
leading supplier of application integration software on the Microsoft platforms.
Their primary markets are healthcare and hospitality. In connection with the
acquisitions we have made in the last nine months, we are re-assessing our cost
structure. We have already consolidated certain of our offices and have
terminated a number of employees in connection with those consolidations, and
expect this to continue. As a result of these efforts, we plan to take a
restructuring charge in the range of $3-$4 million in the third quarter of 1999.

                                  RISK FACTORS

         As described by the following factors, past financial performance
should not be considered a reliable indicator of future performance and
investors should not use historical trends to anticipate results or trends in
future periods.

OUR OPERATING RESULTS FLUCTUATE SIGNIFICANTLY AND WE MAY NOT BE ABLE TO MAINTAIN
OUR HISTORICAL GROWTH RATES.

         Although we have had significant revenue growth in recent quarters,
such growth rates may not be sustainable, and you should not use these past
results to predict future operating margins and results. Our quarterly operating
results have fluctuated significantly in the past and may vary significantly in
the future. Our future operating results will depend on many factors, including
the following:

         -        the continued growth of the Enterprise Application Integration
                  ("EAI") software market;

         -        the size of the orders for our products, and the timing of
                  such orders;

         -        potential delays in our implementations at customer sites;

         -        continued development of indirect distribution channels;

         -        increased demand for our products;

         -        the timing of our product releases;

         -        competition;

         -        the effects of global economic uncertainty on capital
                  expenditures for software;

         -        the effects of Year 2000 issues on software purchases.

         Quarterly revenues and operating results depend upon the volume and
timing of customer contracts received during a given quarter, and the percentage
of each contract which we are able to recognize as revenue during each quarter,
each of which is difficult to forecast. In addition, as is common in the
software industry, a substantial portion of our revenues in a given quarter
historically have been recorded in the third month of that quarter, with a
concentration of such revenues in the last two weeks of the third month. If this
trend continues, any failure or delay in the closing of orders during the last
part of a quarter will have a material adverse effect on our business.

         As a result of these and other factors, we believe that
period-to-period comparisons of our historical results of operations are not a
good predictor of our future performance. If our future operating results are
below the expectations of stock market analysts, our stock price may decline.

SOFTWARE LICENSE REVENUE GROWTH IS INCREASINGLY DEPENDENT ON OUR RELATIONSHIP
WITH IBM.

         Our revenue growth for 1998 and the first quarter of 1999 reflected
strong sales of MQIntegrator through IBM's distribution and reseller channel.
For the first quarter of 1999, royalty revenue from IBM sales of MQIntegrator
accounted for a significant portion of our total software license revenue. In
the first quarter, IBM adopted MQIntegrator as an IBM-branded product known as
MQSeries Integrator. As an IBM-branded product, IBM has assumed production and
fulfillment obligations which is reflected in the royalty structure. IBM
distributors and resellers will sell MQSeries Integrator and we will resell it
both directly and through our indirect channels. We expect that IBM will account
for an increasing percentage of our software license revenue in the remainder of
1999. Accordingly, we are more dependent on IBM's management of the MQSeries
Integrator product, and any delay or shortfall in revenues from IBM, or in our
ability to report revenue, could have a material adverse effect on our business
and operating results.

IF OUR SALES CYCLE IS LONGER THAN WE ANTICIPATE, OUR OPERATING RESULTS MAY
SUFFER.

         Our customers typically take a long time to evaluate our products.
Therefore the timing of license revenue is difficult to predict. A sale of our
products to a customer typically involves a significant technical evaluation and
a commitment of capital and other resources by the customer. This evaluation
process frequently results in a sales cycle that lasts several months.
Additional delays are caused by customers' internal procedures to approve large
capital expenditures and to test, implement and accept new technologies that
affect key operations within their organization. Our operating expense levels
are relatively fixed in the short-term and are based in part on expectations of
future revenues.


                                       5

<PAGE>   7

Consequently, any delay in the recognition of revenue due to a longer sales
cycle caused by these factors could result in operating losses.

WE HAVE A SHORT OPERATING HISTORY AND A HISTORY OF OPERATING LOSSES.

         An investor in our common stock must evaluate the risks, uncertainties,
expenses and difficulties frequently encountered by early stage companies in
rapidly evolving markets. We have had only a limited operating history upon
which an evaluation of our Company and its prospects can be based. Prior to
1996, we recorded only nominal product revenue, and we have not been profitable
on an annual basis. At December 31, 1998, our Company had an accumulated deficit
of approximately $20 million (which includes acquisition-related costs). To
address these risks and uncertainties, we must do the following:

         -        successfully implement our sales and marketing strategy;

         -        expand our direct sales channels;

         -        further develop our indirect distribution channels;

         -        respond to competition;

         -        continue to attract and retain qualified personnel;

         -        continue to develop and upgrade our products and technology
                  more rapidly than competitors;

         -        commercialize our products and services with future
                  technologies.

         We may not successfully implement any of our strategies or successfully
address these risks and uncertainties. Even if we accomplish these objectives we
may not be profitable in the future.

FAILURE TO ADD CUSTOMERS OR EXPAND INTO NEW MARKETS MAY HAVE A MATERIAL ADVERSE
EFFECT ON OUR BUSINESS.

         A significant portion of our revenue has come from a small number of
large purchasers. For example, in 1998 our top ten customers accounted for 38%
of total revenues. In 1998, Industrial Bank of Japan accounted for approximately
10% of our total revenues. Historically, our revenues have been derived
primarily from sales to large banks and financial institutions. For example,
sales to large banks and financial institutions accounted for 57% of total
revenues in 1998 and approximately 72% of total revenues in 1997. These
customers or other customers may not continue to purchase our products. Our
failure to add new customers that make significant purchases of our products and
services would have a material adverse effect on our business, financial
condition and results of operations.

         While we have developed experience marketing our products to financial
institutions, we have less experience with other vertical market segments. New
market segments that we are currently targeting are likely to have significantly
different characteristics than the financial institutions segment. As a result,
we may change our pricing structures, sales methods, sales personnel, consulting
services and customer support. We may not be successful in selling our products
and services to the additional segments targeted. Our inability to expand sales
of our products and services into these additional markets will materially
adversely affect our business.

OUR GROWTH IS DEPENDENT UPON THE SUCCESSFUL DEVELOPMENT OF OUR DIRECT AND
INDIRECT SALES CHANNELS.

         We sell our products primarily through our direct sales force and we
support our customers with our internal technical and customer support staff. We
will continue to rely on our ability to recruit and train additional sales
people and qualified technical support personnel. Our ability to achieve
significant revenue growth in the future will greatly depend on our ability to
recruit and train sufficient technical, customer and direct sales personnel,
particularly additional sales personnel focusing on the new vertical market
segments that we target. We have in the past and may in the future experience
difficulty in recruiting qualified sales, technical and support personnel. Our
inability to rapidly and effectively expand our direct sales force and our
technical and support staff could materially adversely affect our business.


                                       6

<PAGE>   8

         We believe that future growth also will depend on developing and
maintaining successful strategic relationships with distributors, resellers, and
systems integrators. Our strategy is to continue to increase the proportion of
customers served through these indirect channels. We are currently investing,
and plan to continue to invest, significant resources to develop these indirect
channels. This could adversely affect our operating results if these efforts do
not generate license and service revenues necessary to offset such investment.
Also, our inability to recruit and retain qualified distributors, resellers and
systems integrators could adversely affect our results of operations. Another
risk is that because lower unit prices are typically charged on sales made
through indirect channels, increased indirect sales could adversely affect our
average selling prices and result in lower gross margins.

OUR OPERATING RESULTS ARE SUBSTANTIALLY DEPENDENT ON OUR SUITE OF EAI PRODUCTS.

         A substantial majority of our revenues come from the NEON EAI suite of
products and related services, and we expect this pattern to continue.
Accordingly, our future operating results will depend on the demand for our
suite of EAI products and related services by future customers, including new
and enhanced releases that are subsequently introduced. There can be no
assurance that the market will continue to demand our current products or that
we will be successful in marketing any new or enhanced products. If our
competitors release new products that are superior to our products in
performance or price, demand for our products may decline. A decline in demand
for NEON as a result of competition, technological change or other factors would
have a material adverse effect on our business, financial condition and results
of operations.

INABILITY TO INTEGRATE ACQUIRED COMPANIES MAY INCREASE THE COSTS OF RECENT
ACQUISITIONS.

         We may from time to time acquire companies with complementary products
and services in the application integration or other related software markets.
Between September 1997 and June 1999, we acquired eight companies.
These acquisitions will expose us to increased risks and costs, including the
following:

         -        assimilating new operations, systems, technology and
                  personnel;

         -        diverting financial and management resources from existing
                  operations.

         We may not be able to generate sufficient revenues from any of these
acquisitions to offset the associated acquisition costs. We will also be
required to maintain uniform standards of quality and service, controls,
procedures and policies. Our failure to achieve any of these standards may hurt
relationships with customers, employees, and new management personnel. In
addition, our future acquisitions may result in additional stock issuances which
could be dilutive to our stockholders.

         We may also evaluate joint venture relationships with complementary
businesses. Any joint venture we enter into would involve many of the same risks
posed by acquisitions, particularly those risks associated with the diversion of
resources, the inability to generate sufficient revenues, the management of
relationships with third parties, and potential additional expenses, any of
which could have a material adverse effect on our financial condition and
results of operations.

THERE ARE MANY RISKS ASSOCIATED WITH INTERNATIONAL OPERATIONS.

         We continue to expand our international operations, and these efforts
require significant management attention and financial resources. Each version
of our product also has to be localized within each country. We have committed
resources to the opening and integration of additional international sales
offices and the expansion of international sales and support channels. Our
efforts to develop and expand international sales and support channels may not
be successful. International sales are subject to a number of risks, including
the following:

         -        longer payment cycles;

         -        unexpected changes in regulatory requirements;

         -        difficulties and expenses associated with complying with a
                  variety of foreign laws;


                                       7

<PAGE>   9

         -        import and export restrictions and tariffs;

         -        difficulties in staffing and managing foreign operations;

         -        difficulty in accounts receivable collection and potentially
                  adverse tax consequences;

         -        currency fluctuations;

         -        currency exchange or price controls;

         -        political and economic instability abroad.

         Additionally, intellectual property may be more difficult to protect
outside of the United States. International sales can also be affected to a
greater extent by seasonal fluctuations resulting from the lower sales that
typically occur during the summer months in Europe and other parts of the world.
In addition, the market for our products is not as developed outside of North
America. We may not be able to successfully penetrate international markets or
if we do, there can be no assurance that we will grow these markets at the same
rate as in North America.

OUR FAILURE TO MANAGE GROWTH OF OPERATIONS MAY ADVERSELY AFFECT US.

         We must plan and manage effectively in order to successfully offer
products and services and implement our business plan in a rapidly evolving
market. We continue to increase the scope of our operations domestically and
internationally and have grown our headcount substantially. For example, at
January 1, 1996, we had a total of 35 employees and at July 27, 1999 we had a
total of 1050 employees. We may further expand domestically or internationally
through internal growth or through acquisitions of related companies and
technologies. This growth will continue to place a significant strain on our
management systems and resources.

         For us to effectively manage our growth, we must continue to enact the
following measures:

         -        improve our operational, financial and management controls;

         -        improve our reporting systems and procedures;

         -        install new management and information control systems;

         -        expand, train and motivate our workforce.

         In particular, we are currently migrating our existing accounting
software to a packaged application that will allow greater flexibility in
reporting and tracking results. If we fail to install this software in an
efficient and timely manner or if the new systems fail to adequately support our
level of operations, then we could incur substantial additional expenses to
remedy such failure.

WE MUST KEEP PACE WITH TECHNOLOGICAL CHANGE TO REMAIN COMPETITIVE.

         The market for our products is characterized by rapid technological
change, frequent new product introductions and enhancements, changes in customer
demands and evolving industry standards. Our existing products could be rendered
obsolete if we fail to keep up in any of these ways. We have also found that the
technological life cycles of our products are difficult to estimate, partially
because they may vary according to the particular application or vertical market
segment. We believe that our future success will depend upon our ability to
continue to enhance our current product line while we concurrently develop and
introduce new products that keep pace with competitive and technological
developments. These developments require us to continue to make substantial
product development investments.

         Existing Products. We currently serve a customer base with a wide
variety of hardware, software, database, and networking platforms. To gain broad
market acceptance, we believe that we will have to support our products on a
variety of platforms. Our success will depend, among others, on the following
factors:


                                       8

<PAGE>   10

         -        our ability to integrate our products with multiple platforms,
                  especially relative to our competition;

         -        the portability of our products, particularly the number of
                  hardware platforms, operating systems and databases that our
                  products can source or target;

         -        the integration of additional software modules under
                  development with existing products;

         -        our management of software development being performed by
                  third-party developers.

         Future Products. There can be no assurance that we will be successful
in developing and marketing future product enhancements or new products that
respond to technological changes, shifting customer preferences, or evolving
industry standards. We may experience difficulties that could delay these
products. If we are unable to develop and introduce new products or enhancements
of existing products in a timely manner or if we experience delays in the
commencement of commercial shipments of new products and enhancements, then
customers may forego purchases of our products and purchase those of our
competitors.

OUR FAILURE TO MAINTAIN CLOSE RELATIONSHIPS WITH KEY SOFTWARE VENDORS WILL
ADVERSELY AFFECT OUR PRODUCT OFFERING.

         We believe that in order to provide competitive solutions for
heterogeneous, open computing environments, it is necessary to develop, maintain
and enhance close relationships with a wide range of vendors, including
database, Enterprise Resource Planning, supply chain and Electronic Data
Interchange software vendors, as well as hardware and operating system vendors.
There can be no assurance that we will be able to maintain our existing
relationships or develop additional relationships with such vendors. Our failure
to do so could adversely affect the portability of our products to existing and
new platforms and databases and the timing of the release of new and enhanced
products.

OUR INABILITY TO ATTRACT AND RETAIN PERSONNEL MAY ADVERSELY AFFECT US.

         Our success greatly depends on the continued service of our key
technical, sales and senior management personnel. None of these persons are
bound by an employment agreement. The loss of any of our senior management or
other key research, development, sales and marketing personnel, particularly if
lost to competitors, could have a material adverse effect on our future
operating results. In particular George F. (Rick) Adam, our Chief Executive
Officer, and Harold A. Piskiel, our Chief Technology Officer, would be difficult
to replace. Our future success will depend in large part upon our ability to
attract, retain and motivate highly skilled employees. We face significant
competition for individuals with the skills required to perform the services we
offer. We cannot assure that we will be able to retain sufficient numbers of
these highly skilled employees. Because of the complexity of the EAI software
market, we have in the past experienced a significant time lag between the date
on which technical and sales personnel are hired and the time at which such
persons become fully productive, and we expect this pattern to continue.

OUR FAILURE TO ADEQUATELY PROTECT OUR PROPRIETARY RIGHTS MAY ADVERSELY AFFECT
US.

         Our success and ability to compete is dependent in part upon our
proprietary technology. We rely on a combination of copyright, trademark and
trade secret laws, as well as confidentiality agreements and licensing
arrangements, to establish and protect our proprietary rights. We presently have
no patents, but we have three patent applications pending. Despite our efforts
to protect our proprietary rights, existing copyright, trademark and trade
secret laws afford only limited protection. In addition, the laws of certain
foreign countries do not protect our rights to the same extent as do the laws of
the United States. Attempts may be made to copy or reverse engineer aspects of
our products or to obtain and use information that we regard as proprietary.
Accordingly, there can be no assurance that we will be able to protect our
proprietary rights against unauthorized third-party copying or use. Any
infringement of our proprietary rights could materially adversely affect our
future operating results. Furthermore, policing the unauthorized use of our
products is difficult and litigation may be necessary in the future to enforce
our intellectual property rights, to protect our trade secrets or to determine
the validity and scope of the proprietary rights of others. Such litigation
could result in substantial costs and diversion of resources and could have a
material adverse effect on our future operating results.


                                       9

<PAGE>   11

INTELLECTUAL PROPERTY CLAIMS CAN BE COSTLY AND RESULT IN THE LOSS OF SIGNIFICANT
RIGHTS.

         It is also possible that third parties will claim that we have
infringed their current or future products. We expect that EAI software
developers will increasingly be subject to infringement claims as the number of
products in different industry segments overlap. Any claims, with or without
merit, could be time-consuming, result in costly litigation, cause product
shipment delays, or require us to enter into royalty or licensing agreements,
any of which could have a material adverse effect upon our operating results.
There can also be no assurance that such royalty or licensing agreements, if
required, would be available on terms acceptable to us, if at all. There can be
no assurance that legal action claiming patent infringement will not be
commenced against us, or that we would prevail in such litigation given the
complex technical issues and inherent uncertainties in patent litigation. In the
event a patent claim against us was successful and we could not obtain a license
on acceptable terms or license a substitute technology or redesign to avoid
infringement, our business, financial condition and results of operations would
be materially adversely affected.

GLOBAL ECONOMIC UNCERTAINTY MAY AFFECT THE CAPITAL EXPENDITURES OF OUR
CUSTOMERS.

         The EAI software market could be negatively impacted by certain generic
factors, including global economic difficulties and uncertainty, reductions in
capital expenditures by large customers, and increasing competition. These
factors could in turn give rise to longer sales cycles, deferral or delay of
customer purchasing decisions, and increased price competition. The presence of
such factors in the EAI software market could adversely affect our operating
results.

YEAR 2000 RISKS MAY RESULT IN MATERIAL ADVERSE EFFECTS ON OUR BUSINESS.

         Many currently installed computer systems and software products are
coded to accept only two digit entries in the date code field. Beginning in the
year 2000, these code fields will need to accept four digit entries to
distinguish 21st century dates from 20th century dates. As a result, in a little
over a year, computer systems and/or software products used by many companies
may need to be upgraded to comply with such year 2000 requirements. While we
have assessed our products, services and internal systems, certain internal
financial packages have not yet been implemented and may require further
assessment by us. We believe we are currently expending sufficient resources to
review our products and services, as well as our internal management information
system in order to remedy those products, services and systems that are not year
2000 compliant. We expect such modifications will be made on a timely basis and
we do not believe that the cost of such modifications will have a material
effect on our operating results. There can be no assurance, however, that we
will be able to modify such products, services and systems in a timely and
successful manner to comply with the year 2000 requirements, which could have a
material adverse effect on our operating results. Moreover, we believe that some
customers may be purchasing our products as an interim solution to their year
2000 needs until their current suppliers reach compliance. Conversely, year 2000
issues could cause a significant number of companies, including our current
customers, to reevaluate their current system needs and as a result consider
switching to other systems and suppliers. Any of the foregoing could result in a
material adverse effect on our business, operating results and financial
condition. Additionally, during the next twelve months there is likely to be an
increased customer focus on addressing year 2000 issues, creating the risk that
customers may reallocate capital expenditures to fix year 2000 problems of
existing systems. If customers defer purchases of our software because of such a
reallocation, it could adversely affect our operating results. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."

OUR STOCK PRICE HAS BEEN HIGHLY VOLATILE.

         The trading price of our common stock has fluctuated significantly
since our initial public offering in June 1997. In addition, the trading price
of our common stock could be subject to wide fluctuations in response to
quarterly variations in operating results, announcements of technological
innovations or new products by us or our competitors, developments with respect
to patents or proprietary rights, changes in financial estimates by securities
analysts and other events or factors. In addition, the stock market has
experienced volatility that has particularly affected the market prices of
equity securities of many high technology companies and that often has been
unrelated or disproportionate to the operating performance of such companies.
These broad market fluctuations may adversely affect the market price of our
common stock.

ADOPTION OF THE EURO PRESENTS UNCERTAINTIES FOR OUR COMPANY.

         In January 1999, the new "Euro" currency is scheduled to be introduced
in certain European countries that are part of the European Monetary Union, or
EMU. During 2002, all EMU countries are expected to be operating with the Euro
as their single currency. A significant amount of uncertainty exists as to the
effect the Euro will have on the marketplace generally and, additionally, all of
the final rules and regulations have not yet been defined and finalized by the
European Commission with regard to the Euro currency. We are currently assessing
the effect the introduction of the Euro will have on our internal accounting
systems and the sales of our products. We are not aware of any material
operational issues or costs associated with preparing our internal systems for
the Euro. However, we do utilize third party vendor equipment and software
products that may or may not be EMU compliant. Although we are currently taking
steps to address the impact, if any, of EMU compliance for such third party
products, the failure of any critical components to operate properly post-Euro
may have an adverse effect on the business or results of operations of our
Company or require us to incur expenses to remedy such problems.

                                 USE OF PROCEEDS

         We will not receive any proceeds from the sale of the common stock by
the Selling Stockholders. All net proceeds from the sale of the common stock
covered by this prospectus will go to the Selling Stockholders who offer and
sell their shares.

                              SELLING STOCKHOLDERS

         The following table sets forth the number of shares owned by each of
the Selling Stockholders as of July 27, 1999. None of the Selling Stockholders
has had a material relationship with NEON within the past three years other than
as described below or as a result of the ownership of the shares or other
securities of NEON. None of the Selling Stockholders holds a number of shares
that exceeds 1% of NEON's outstanding capitalization. No estimate can be given
as to the amount of shares that will be held by the Selling Stockholders after
completion of this offering because the Selling Stockholders may offer all or
some of the shares and because there currently are no agreements, arrangements
or understandings with respect to the sale of any of the shares. The shares
offered by this prospectus may be offered from time to time by the Selling
Stockholder named below.

   (1)   Does not include an aggregate of 431,651 shares of common stock
         beneficially owned by the Selling Stockholders that have been deposited
         in escrow to secure the indemnification obligations of the Selling
         Stockholders. A number of shares equivalent to these escrow shares have
         been included in this registration statement, but they are not included
         in this column of the table. A prospectus supplement will be filed to
         reflect any change in the number of shares offered by the individual
         selling stockholders as a result of the expiration of the escrow.

                              PLAN OF DISTRIBUTION

         We are registering all 1,515,123 shares of common stock (the "Shares")
on behalf of the Selling Stockholders. As used in this prospectus, "Selling
Stockholders" includes the pledgees, donees, transferees or other successors in
interest that receive such shares as a gift, partnership distribution or other
non-sale related transfer. The Shares may be offered and sold from time to time
by the Selling Stockholders. The Selling Stockholders will act independently of
NEON in making decisions with respect to the timing, manner and size of each
sale.

         The Selling Stockholders may sell the Shares in the over-the-counter
market or otherwise, at (1) market prices prevailing at the time of sale, (2)
prices related to the prevailing market prices or (3) negotiated prices. The
Selling Stockholders may sell some or all of their Shares through:

         o        a block trade in which a broker-dealer may resell a portion of
                  the block, as principal, in order to facilitate the
                  transaction;

         o        purchases by a broker-dealer as principal and resale by such
                  broker-dealer for its own account;

         o        an over-the-counter distribution in accordance with the rules
                  of the Nasdaq National Market;

         o        ordinary brokerage transactions and transactions in which the
                  broker solicits purchasers; or

         o        in privately negotiated transactions.

To the extent required, this prospectus may be amended and supplemented from
time to time to describe a specific plan of distribution.

         In connection with the distribution of the Shares, the Selling
Stockholders may also enter into hedging transactions with broker-dealers or
other financial institutions. In connection with such transactions,
broker-dealers or other financial institutions may engage in short sales of
NEON's common stock in the course of hedging the positions they assume with the
Selling Stockholders. The Selling Stockholders may also:

         o        sell NEON common stock short and redeliver the Shares to close
                  out such short positions;

         o        enter into option or other types of transactions that require
                  the Selling Stockholder to deliver the Shares to a
                  broker-dealer, who will then resell or transfer the Shares
                  pursuant to this prospectus (as supplemented or amended to
                  reflect such transaction); or

         o        loan or pledge the Shares to a broker-dealer, who may sell the
                  loaned shares or, in the event of default, sell the pledged
                  shares pursuant to this prospectus (as supplemented or amended
                  to reflect such transaction).

         In addition, any Shares that qualify for sale pursuant to Rule 144 may
be sold under Rule 144 rather than pursuant to this prospectus.

         The Selling Stockholders may negotiate and pay broker-dealers
commissions, discounts or concessions for their services. Broker-dealers engaged
by the Selling Stockholders may allow other broker-dealers to participate in
resales. However, the Selling Stockholders and any broker-dealers involved in
the sale or resale of the Shares may qualify as "underwriters" within the
meaning of the Securities Act. In addition, the broker-dealers' commissions,
discounts or concessions may qualify as underwriters' compensation under the
Securities Act. If the Selling Stockholders qualify as "underwriters," they will
be subject to the prospectus delivery requirements of Section 153 of the Act,
which may include delivery through the facilities of the NASD. NEON will pay all
expenses incident to the offering and sale of the Shares to the public other
than any commissions and discounts of underwriters, dealers or agents and any
transfer taxes.

         We have advised the Selling Stockholders that the anti-manipulation
rules of Regulation M under the Exchange Act may apply to sales of Shares in the
market and to the activities of the Selling Stockholders and their affiliates.
In addition, we will make copies of this prospectus available to the Selling
Stockholders, and we have informed them of the need for delivery of copies of
this prospectus to purchasers at or prior to the time of any sale of the Shares
offered hereby. The Selling Stockholders may indemnify any broker-dealer that
participates in transactions involving the sale of the shares against certain
liabilities, including liabilities arising under the Securities Act.

         At the time a particular offer of Shares is made, if required, a
Prospectus Supplement will be distributed that will set forth the number of
Shares being offered and the terms of the offering, including the name of any
underwriter, dealer or agent, the purchase price paid by any underwriter, any
discount, commission and other item constituting compensation,


                                       13

<PAGE>   15

any discount, commission or concession allowed or reallowed or paid to any
dealer, and the proposed selling price to the public.

         The sale of Shares by the Selling Stockholders is subject to compliance
by the Selling Stockholders with certain contractual restrictions they have with
us. There can be no assurance that the Selling Stockholders will sell all or any
of the Shares.

         NEON has agreed to indemnify certain Selling Stockholders against
certain liabilities, including liabilities under the Securities Act. In return,
certain Selling Stockholders have agreed to indemnify NEON and certain related
persons against certain liabilities, including liabilities under the Securities
Act.

                                  LEGAL MATTERS

         The validity of the common stock offered hereby will be passed upon for
NEON by Wilson Sonsini Goodrich & Rosati, Professional Corporation, Palo Alto,
California.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS

    Section 145 of the Delaware General Corporation Law Code authorizes a court
to award, or a corporation's Board of Directors to grant, indemnity to directors
and officers in terms sufficiently broad to permit such indemnification under
certain circumstances for liabilities (including reimbursement for expenses
incurred) arising under the Securities Act of 1933, as amended (the "Securities
Act"). Article VII of the Registrant's Certificate of Incorporation and Article
VI of the Registrant's Bylaws provide for mandatory indemnifications of its
directors and officers and permissible indemnifications of employees and offer
agents to the maximum extent permitted by the Delaware General Corporation Law.
In addition, the Registrant has entered into Indemnification Agreements with its
officers and directors.

ITEM 17. 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.

                  (iii)    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 a 20% change in the
                           maximum

                           aggregate offering price set forth in the
                           "Calculation of Registration Fee" table in the
                           effective registration statement.

                  (iv)     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.

         (2)      That, for the purpose of determining any 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 bona
                  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.

         The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities 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) that is incorporated by reference in the 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.

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the 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.

                           SHARE ACQUISITION AGREEMENT

     This SHARE ACQUISITION AGREEMENT (the "Agreement") is made and entered into
as of February 19, 1999 by and among New Era of Networks, Inc., a Delaware
corporation ("NEON"), Andrew Street and Michael Eugene Tinworth (each directly
or indirectly a shareholder of the Company hereinafter referred to individually
as a "Shareholder" and collectively as the "Shareholders") and, with respect to
Articles VI and VII, Andrew Street (in his capacity as the "Shareholder
Representative").

                                    RECITALS

     A. The Board of Directors of NEON believes it is in the best interests of
NEON and its shareholders that NEON acquire all of the issued and outstanding
share capital of D&M (Asia) Ltd., a corporation organized under the laws of Hong
Kong (the "Company"), owned or held of record by the Shareholders (the
"Acquisition") such that upon consummation of the acquisition NEON will be the
sole beneficial owner of all of the issued and outstanding share capital of the
Company and, in furtherance thereof, has approved the Acquisition.

     B. The Shareholders desire to sell all of the share capital of the Company
owned or held of record by them to NEON, all upon the terms and subject to the
conditions set forth herein.

     C. As an inducement for NEON to consummate the Acquisition, the Company and
the Shareholders agree to make certain representations, warranties, covenants
and other agreements in connection with the Acquisition.

     D. A portion of the consideration otherwise payable by NEON in connection
with the Acquisition shall be placed in escrow by NEON for the purposes of
satisfying damages, losses, expenses and other similar charges which result from
breaches of representations, warranties and covenants.

     E. As an inducement for NEON to consummate the Acquisition, each of the
Shareholders have agreed to enter into Confidential Information and
Non-Competition Agreements of even date herewith (the "Confidentiality
Agreement") in substantially the form attached hereto as Exhibit A, which
Non-Competition Agreements shall be effective only upon the closing of the
Acquisition.

     NOW, THEREFORE, in consideration of the covenants, promises and
representations set forth herein, and for other good and valuable consideration,
the parties agree as follows:

     1.1 Purchase and Sale. At the Closing (as defined in Section 1.3) NEON is
purchasing, upon the terms of this Agreement, from each Shareholder and each
Shareholder is selling, conveying, transferring, assigning and delivering to
NEON, free and clear of all liens, encumbrances or other defects of title, all
of the issued and outstanding shares of share capital of the Company
beneficially owned or held of record by the Shareholders at the Closing (the
"Shares"), including all property or rights issued by the Company with respect
to the Shares. The name and address of each Shareholder and the number and
description of such Shares being sold by such Shareholder pursuant hereto, and
the consideration payable in connection there are set forth in Schedule 1.1

in the amount of $2,400,000 (the "Cash Consideration") and (ii) that number of

third trading day immediately preceding the Closing Date and rounded to the
nearest whole share (the "Stock Consideration," and, collectively with the Cash
Consideration, the "Purchase Price"); provided, however, that NEON shall
withhold that number of shares equal to 15% of the Stock Consideration (the
"Escrow Shares") and 15% of the Cash Consideration (the "Escrow Cash", and,

Shareholders under Article VI hereof pursuant to the provisions of an escrow
agreement substantially in the form of Exhibit B (attached) hereto (the "Escrow
Agreement").

violation or default under any such license, sublicense or agreement, nor
entitle any other party to any such license, sublicense or agreement to
terminate or modify such license, sublicense or agreement. Except as set forth
in Schedules 2.13(a) or 2.13(b), the Company is the sole and exclusive owner or

     3.2 Tax Matters. Such Shareholder has had an opportunity to review with its
own tax advisors the tax consequences to such Shareholder of the Acquisition and
the transactions contemplated by this Agreement. Such Shareholder understands
that it must rely solely on its advisors and not on any statements or

understands that it (and not NEON or the Company) shall be responsible for its
own tax liability that may arise as a result of the Acquisition or the
transactions contemplated by this Agreement.

     3.3 Absence of Claims by the Shareholders. Such Shareholder does not have
any present claim against the Company and does not have knowledge of the basis

Agreement and the Shareholders Agreement in the form attached hereto as Exhibit
C and to consummate the transactions contemplated hereby and thereby, and no
further action is required on the part of such Shareholder to execute this
Agreement and the Shareholders Agreement. This Agreement and the Shareholders
Agreement have been duly executed and delivered by such Shareholder and,
assuming the due authorization, execution and delivery by the other parties
thereto, constitute the valid and binding obligations of each such Shareholder,
enforceable in accordance with their terms, except as such enforceability may be
limited by principles of public policy and subject to the laws of general


                                      -25-

or any of its properties or assets are subject (a "Shareholder Conflict"), or
(iii) any judgment, order, decree, statute, law, ordinance, rule or regulation
applicable to such Shareholder or its properties or assets.

     3.6 Consents. No consent, waiver, approval, order or authorization of, or
registration, declaration or filing with, any Governmental Entity or any third
party (so as not to trigger any Shareholder Conflict), is required by or with
respect to such Shareholder in connection with the execution and delivery of
this Agreement or the Shareholders Agreement or the consummation of the
transactions contemplated hereby or thereby except for such consents, waivers,
approvals, orders, authorizations, registrations, declarations and filings as

Securities Act of 1933, as amended, on the basis that the issuance of securities
hereunder is exempt from registration under said Act pursuant to Regulation S
and section 4(2) and/or Rule 506 thereof, and that NEON's reliance on such
exemption is based on Shareholder's representations set forth in the Stockholder
Agreement.

     4.3 Capital Structure. The authorized stock of NEON consists of 45,000,000
shares of Common Stock, of which 30,333,778 shares were issued and outstanding
as of December 31, 1998, and 2,000,000 shares of Preferred Stock, none of which
is issued or outstanding. No shares of NEON Common Stock were held by NEON in
its treasury, and no shares of NEON Preferred Stock were outstanding. All the
outstanding shares of NEON Common Stock are validly issued, fully paid,
nonassessable and free of preemptive rights. The shares of NEON Common Stock
issuable in connection with the Acquisition have been duly authorized and
reserved for issuance and, when issued in accordance with the terms of this
Agreement, will be validly issued, fully paid, nonassessable and free of
preemptive rights.

     4.4 SEC Documents; NEON Financial Statements. NEON has furnished or made
available to the Company and the Shareholders true and complete copies of all
reports or registration statements filed by it with the Securities and Exchange
Commission ("SEC") under the Securities Exchange Act of 1934, as amended (the
"Exchange Act") for all periods since January 1, 1998, all in the form so filed
(all of the foregoing being collectively referred to as the "SEC Documents"). As
of their respective filing dates, the SEC Documents complied in all material
respects with the requirements of the Securities Act of 1933, as amended (the
"Securities Act") or the Exchange Act, as the case may be, and none of the SEC
Documents contained any untrue statement of a material fact or omitted to state
a material fact required to be stated therein or necessary to make the
statements made therein, in light of the circumstances in which they were made,
not misleading, except to the extent corrected by a document subsequently filed
with the SEC. The financial statements of NEON, including the notes thereto,
included in the SEC Documents (the "NEON Financial Statements") comply as to
form in all material respects with applicable accounting requirements and with
the published rules and regulations of the SEC with respect thereto, have been
prepared in accordance with GAAP consistently applied (except as may be
indicated in the notes thereto or, in the case of unaudited statements, as
permitted by Form 10-Q of the SEC) and present fairly the consolidated financial
position of NEON at the dates thereof and the consolidated results of its
operations and cash flows for the periods then ended (subject, in the case of
unaudited statements, to normal audit adjustments).

     4.5 Litigation. There is no action, suit proceeding, claim, arbitration or
investigation pending, or as to which NEON has received any notice of assertion
against NEON, which in any manner challenges or seeks to prevent, enjoin, alter
or materially delay any of the transactions contemplated by this Agreement.

        SURVIVAL OF REPRESENTATIONS AND WARRANTIES; INDEMNITY AND ESCROW

     6.1 Survival of Representations and Warranties. The Shareholders' and
NEON's representations and warranties in this Agreement or in any instrument
delivered pursuant to this Agreement shall survive the Closing and shall
terminate on the first anniversary of the Closing (the "Expiration Date");
provided, however, that (i) the representations and warranties and covenants of
the Shareholders relating or pertaining to any Tax or Returns related to such
Tax set forth in Section 2.10 hereof, shall survive until the expiration of all
applicable statutes of limitations, or extensions thereof, governing each Tax or
Returns related to such Tax and (ii) the representations and warranties of the
Shareholders set forth in Section 2.3 and Article III hereof shall survive the
Closing and shall terminate on the fourth anniversary of the Closing. Each
shareholder, jointly and severally, shall indemnify and hold harmless NEON and
its affiliates for any Loss (as defined in the Escrow Agreement) incurred by
NEON, its officers, directors or affiliates, related to or arising, directly or
indirectly, out of any breach of the representations and warranties set forth in
Sections 2.10, 2.3 and Article III of this Agreement.

     6.2 Indemnity and Escrow Agreement. At the Closing each Shareholder will be
deemed to have received and consented to the deposit with the Escrow Agent of
the Escrow Cash and the Escrow Shares (plus any additional shares as may be
issued upon any stock split, stock dividend or


                                      -28-
<PAGE>   33


recapitalization effected by NEON after the Closing) pursuant to the terms of
the Escrow Agreement attached hereto as Exhibit B, without any act required on
the part of the Shareholders. At the Closing, the Escrow Cash and the Escrow
Shares, without any act required on the part of the Shareholders, are being
deposited with the Escrow Agent, such deposit to constitute the Escrow Fund to
be governed by the terms set forth in the Escrow Agreement and at NEON's cost
and expense. The Escrow Fund and the related indemnification obligations of the
Shareholders shall be governed by the terms of the Escrow Agreement.

to be illegal, void or unenforceable, the remainder of this Agreement will

of such provision to other persons or circumstances will be interpreted so as

remedies herein expressly conferred upon a party will be deemed cumulative with
and not exclusive of any other remedy conferred hereby, or by law or equity upon

                           SHARE ACQUISITION AGREEMENT

         This SHARE ACQUISITION AGREEMENT (the "Agreement") is made and entered
into as of February 19, 1999 by and among New Era of Networks, Inc., a Delaware
corporation ("NEON"), Andrew Street and Michael Eugene Tinworth (each directly
or indirectly a shareholder of the Company hereinafter referred to individually
as a "Shareholder" and collectively as the "Shareholders") and, with respect to
Articles VI and VII, Andrew Street (in his capacity as the "Shareholder
Representative").

                                    RECITALS

         A. The Board of Directors of NEON believes it is in the best interests
of NEON and its shareholders that NEON acquire all of the issued and outstanding
share capital of Database & Management (S) Pte. Ltd., a corporation organized
under the laws of Singapore (the "Company"), owned or held of record by the
Shareholders (the "Acquisition") such that upon consummation of the acquisition
NEON will be the sole beneficial owner of all of the issued and outstanding
share capital of the Company and, in furtherance thereof, has approved the
Acquisition.

         B. The Shareholders desire to sell all of the share capital of the
Company owned or held of record by them to NEON, all upon the terms and subject
to the conditions set forth herein.

         C. As an inducement for NEON to consummate the Acquisition, the Company
and the Shareholders agree to make certain representations, warranties,
covenants and other agreements in connection with the Acquisition.

         D. A portion of the consideration otherwise payable by NEON in
connection with the Acquisition shall be placed in escrow by NEON for the
purposes of satisfying damages, losses, expenses and other similar charges which
result from breaches of representations, warranties and covenants.

         E. As an inducement for NEON to consummate the Acquisition, each of the

         2.11 Restrictions on Business Activities. Except as set forth in
Section 2.11 of the Company Disclosure Schedule, there is no agreement
(noncompete or otherwise), commitment, judgment, injunction, order or decree to
which the Company is a party or otherwise binding upon the Company which has the
effect of prohibiting or impairing any line of business or business practice
(including without limitation the licensing of any product) of the Company, any
acquisition of property (tangible or intangible) by the Company or the conduct
of business by the Company which has a Material Adverse Effect. The Company is
not a party to and is not currently bound by any agreement under which the
Company is restricted from selling, licensing or otherwise distributing any of
its technology or products to or providing services to, customers or potential
customers or any class of customers, in any geographic area, during any period
of time or in any segment of the market which has or would reasonably be
expected to have a Material Adverse Effect.

         2.12 Title of Properties; Absence of Liens and Encumbrances; Condition
of Equipment.

              (a) The Company does not own any real property, nor has it ever
owned any real property. Section 2.12(a) of the Company Disclosure Schedule sets
forth a list of all real property leased by the Company as of the Closing, the
name of the lessor, the date of the lease and each amendment thereto and, with
respect to any current lease, the aggregate annual rental and/or other fees
payable under any such lease. All such current leases are in full force and
effect, and there is not, under any of such leases, any existing material
default or event of default by the Company (or event which with notice or lapse
of time, or both, would constitute a default by the Company); provided, however,
that any material adverse financial impact on the Company of such breach shall
constitute a material default.

              (b) The Company has good and valued title to, or in the case of
leased properties and assets, valid leasehold interests in, all of its tangible
properties and assets, real, personal and mixed, used or held for use in its
business, free and clear of any Liens, except as set forth in Section 2.14 of
the Company Disclosure Schedule or as reflected in the Current Balance Sheet,
and except for Liens for Taxes not yet due and payable and such imperfections of
title and encumbrances, if any, which are not material in character, amount or
extent, and which do not materially detract from the value, or materially
interfere with the present use, of the property subject thereto or affected
thereby.

              (c) Section 2.12(c) of the Company Disclosure Schedule lists all
material items of equipment (the "Equipment") owned or leased by the Company and
such Equipment is, (i) adequate for the conduct of the business of the Company
as currently conducted and (ii) in good operating condition, regularly and
properly maintained, subject to normal wear and tear.

              (d) The Company has sole and exclusive ownership, free and clear

in its possession relating to its current and former customers (the "Customer
Information"). No person other than the Company possesses any claims or rights
with respect to use of the Customer Information.

         2.13 Intellectual Property.

              (a) The Company owns, or is licensed or otherwise possesses
legally enforceable rights to use, all registered and unregistered trademarks,
trade names, service marks, trade secrets, copyrights, and any applications
therefor, schematics, technology, know-how, computer software programs or
applications (in both source code and object code form), and tangible or
intangible proprietary information or material that are required for the conduct
of business of the Company as currently conducted by the Company or as such
rights relate to services offered or products currently under development (the
"Company Intellectual Property").

              (b) Schedule 2.13(a) sets forth a complete list of all registered
and unregistered trademarks, registered copyrights, trade names and service
marks, and any applications therefor, included in the Company Intellectual
Property, and specifies, where applicable, the jurisdictions in which such
Company Intellectual Property has been issued or registered or in which an
application for such issuance and registration has been filed, including the
respective registration or application numbers and the names of all registered
owners. Schedule 2.13(b) sets forth a complete list of all material licenses,
sublicenses and other agreements to which the Company is a party and pursuant to
which the Company or any other person is authorized to use any Company
Intellectual Property or trade secret of the Company, and includes the identity
of all parties thereto, a description of the nature and subject matter thereof,
the applicable royalty or other fees and the term thereof. The execution and
delivery of this Agreement by the Company, and the consummation of the
transactions contemplated hereby, will neither cause the Company to be in
violation or default under any such license, sublicense or agreement, nor
entitle any other party to any such license, sublicense or agreement to
terminate or modify such license, sublicense or agreement. Except as set forth
in Schedules 2.13(a) or 2.13(b), the Company is the sole and exclusive owner or
licensee of, with all right, title and interest in and to (free and clear of any
liens or encumbrances but subject to the license rights of customers under
customer agreements, which customer agreements have been disclosed in the
Company Schedules to the extent required elsewhere herein), the Company
Intellectual Property, and has sole and exclusive rights (and is not
contractually obligated to pay any compensation to any third party in respect
thereof) to the use thereof or the material covered thereby in connection with
the services or products in respect of which the Company Intellectual Property
is being used.

              (c) No claims with respect to the Company Intellectual Property
have been asserted or, to the Shareholder's knowledge, threatened by any person,
nor, to the Shareholder's knowledge, has any other person made an assertion (i)
against the use by the Company of any trademarks, service marks, trade names,
trade secrets, copyrights, patents, technology, know-how or computer software
programs and applications used in the Company's business as currently conducted
by the Company, or (ii) challenging the ownership by the Company, validity or
effectiveness of any of the Company Intellectual Property. All registered
trademarks, service marks and copyrights held by the Company are valid and
subsisting. To the best of the Shareholder's knowledge, the Company has not
infringed, and the business of the Company as currently conducted



                                      -13-
<PAGE>   18

or as currently proposed to be conducted does not infringe, any copyright,
patent, trademark, service mark, trade secret or other proprietary right of any
third party. There is no material unauthorized use, infringement or
misappropriation of any of the Company Intellectual Property by any third party,
including any employee or former employee of the Company. No Company
Intellectual Property is subject to any outstanding decree, order, judgment, or
stipulation restricting in any material manner the use or licensing thereof by
the Company. Each employee, consultant or contractor of the Company has executed
a proprietary information and confidentiality agreement substantially in the
Company's standard forms.

              (d) Section 2.13(d) of the Company Disclosure Schedule lists all
contracts, licenses and agreements between the Company and any other person
wherein or whereby the Company has agreed to, or assumed, any material
obligation or duty to warrant, indemnify, reimburse, hold harmless, guaranty or
otherwise assume or incur any material obligation or liability with respect to
the infringement or misappropriation by the Company or such other person of the
intellectual property of any person or entity other than the Company.

              (e) The Company has taken reasonable steps to ensure that any
products, software programs or technology developed (or currently being
developed) for its customers and other third parties, whether as "work-for-hire"
or otherwise, will accurately record, store, process, calculate and present
calendar dates falling on and after (and if applicable, spans of time including)
January 1, 2000, and will calculate any information dependent on or relating to
such dates in the same manner, and with the same functionality, data integrity
and performance, as the products record, store, process, calculate and present
calendar dates on or before December 31, 1999, or calculate any information
dependent on or relating to such dates (collectively, "Year 2000 Compliant").
The Company has taken reasonable steps to ensure that such products and programs
will lose no functionality with respect to the introduction of records
containing dates falling on or after January 1, 2000. All of the Company's
internal computer and technology products and systems are Year 2000 Compliant.

         2.14 Agreements, Contracts and Commitments. Except as set forth in
Sections 2.13(b), 2.13(d) or 2.14(a) of the Company Disclosure Schedule, the

Each Contract is in full force and effect and, except as otherwise disclosed in

ongoing fees, royalties or payments which the Company would otherwise be
required to pay had the transactions contemplated by this Agreement not

Memorandum and Articles of Association of the Company or otherwise, on or for
the sale or transfer of the Shares to Neon and/or its nominees pursuant to this

challenged or questioned the legal right of the Company to conduct its
operations as presently or previously conducted. Section 2.17 of the Company
Disclosure Schedule sets forth, with respect to any pending or threatened
action, suit, proceeding or investigation, the forum, the parties thereto, the

requested.

Accounts Receivable, and no request or agreement for deduction or discount has
been made with respect to any of such Accounts Receivable.

for NEON are the only minutes of the Company and contain a reasonably accurate
summary of all meetings of the Board of Directors (or committees thereof) of the
Company and its shareholders or actions by written consent since the time of

the Company may from time to time required to keep, of the Company have been
properly and duly kept and contain true, accurate and complete records of all

pending, or to the knowledge of either Shareholder, threatened. The Company is
not involved in nor is being threatened with any labor dispute, grievance, or
litigation relating to labor, safety or discrimination matters involving any
Employee, including, without limitation, charges of unfair labor practices or
discrimination complaints, which, if adversely determined, would, individually
or in the aggregate, result in a material liability to the Company. The Company
has not engaged in any unfair labor practices which could, individually or in
the aggregate directly or indirectly result in a material liability to the
Company. The Company is not presently, nor has it in the past, been a party to,
or bound by, any collective bargaining agreement or union contract with respect
to Employees and no collective bargaining agreement is being negotiated by the
Company.

              (l) No Interference or Conflict. To the knowledge of either
Shareholder, no shareholder, officer, employee or consultant of the Company is
obligated under any contract or agreement or subject to any judgement, decree or
order of any court or administrative agency, that would interfere with such
person's efforts to promote the interests of the Company or that would



                                      -21-

materially interfere with the Company's business. Neither the execution nor
delivery of this Agreement, nor the carrying on of the Company's business as
presently conducted or proposed to be conducted nor any activity of such
officers, directors, employees or consultants in connection with the carrying on
of the Company's business as presently conducted or proposed to be conducted,
will, to either Shareholder's knowledge, conflict with or result in a breach of
the terms, conditions or provisions of, or constitute a default under, any
contract or agreement under which any of such officers, directors, employees or
consultants is now bound. Neither Shareholder has received notice of or is
currently aware of any senior employee or key personnel who intends to terminate
his/her employment with the Company.

         2.23 Insurance. Section 2.23 of the Company Disclosure Schedule lists
all insurance policies and fidelity bonds covering the assets, business,
equipment, properties, operations, employees, officers and directors of the
Company or any Affiliate. There is no material claim by the Company or any
Affiliate pending under any of such policies or bonds as to which coverage has
been questioned, denied or disputed by the underwriters of such policies or
bonds. All premiums due and payable under all such policies and bonds have been
paid or accrued, and the Company and its Affiliates are otherwise in material
compliance with the terms of such policies and bonds (or other policies and
bonds providing substantially similar insurance coverage). Neither the Company
nor any Shareholder has knowledge of any threatened termination of, or premium
increase with respect to, any of such policies. The Company is now and has at
all material times taken out all necessary insurance which it is required to
take out by law and otherwise normally taken out against risks normally insured
against by persons carrying on the same business as that carried on by it. All
assets as disclosed in the Year End Financials are adequately insured in
accordance with prudent business practice in the relevant country and there has
been no failure by the Company to comply with any conditions in any relevant
policies.

         2.24 Compliance with Laws. The Company has materially complied with, is
not in material violation of, and has not received any notices of violation with
respect to, any foreign, federal, state or local statute, law or regulation
(except for notices of violations which have been cured in all material
respects). All annual returns and other returns, particulars, resolutions and
documents required to be filed with the Registrar of Companies of Hong Kong or
to any other authority under any relevant legislation in Hong Kong or any other
applicable jurisdiction in respect of the Company have been duly filed within
any applicable time limit and were correct and all legal requirements relating
to the formation of the Company and the issue of the Shares have been duly
complied with in a timely manner. The Company has complied with its Memorandum
and Articles of Association in all respects and none of the activities,
agreements, commitments or rights of the Company (including without limitation,
its execution and delivery of this Agreement and the performance of its
obligations under this Agreement) is ultra vires, unauthorised or otherwise in
breach of any legal provisions.

         2.25 Warranties; Indemnities. Except in the ordinary course of business
or as listed in Section 2.13(d) of the Company Disclosure Schedule or as set
forth in a Contract, the Company has

Section 2.27 of the Company Disclosure Schedule and presently employed by the
Company has executed a proprietary information agreement substantially in the
Company's standard form (as revised or modified, from time to time) samples of
which are attached hereto as part of Section 2.27 of the Company Disclosure
Schedule. Such proprietary information agreements constitute valid and binding
obligations of the Company.

         2.29 Representations Complete. Without limiting in any way any
representations or warranties made by the Shareholders, none of the
representations or warranties made by the Shareholders (as modified by the
Company Disclosure Schedule), nor any statement made in any Schedule or
certificate furnished by any Shareholder pursuant to this Agreement contains or

         2A.1 The representations, warranties and undertakings contained in
Articles II and/or III in this Agreement (together the "Warranties") are in all
respects qualified and limited by the provisions of this Article IIA to the
extent that none of the Shareholders shall be liable in any way under the
Warranties or for any claim under the Warranties nor under any indemnity

or Audited Financials; or

              (b) to the extent that a claim arises:

                 (i) as a result of an act occurring at the request of or with
the written consent of NEON or (on or after the date hereof) the Company
provided that such written consent was given with full knowledge of the
applicable facts and circumstances so as to be able to make an informed
decision; or

transactions in the ordinary course of business of the Company effective since
the Closing Date; or

              (d) in respect of any claim to the extent to which it would not
have arisen but for any matter or thing done or omitted to be done by the
Company or NEON or persons deriving title therefrom on or after the Closing Date
and based on facts and circumstances that exist on or after the Closing Date
(other than the purchase of the Sale Shares by NEON) unless such matter or thing
is necessarily done or necessarily omitted to be done as a direct consequence of

                         REPRESENTATIONS AND WARRANTIES
                               OF THE SHAREHOLDERS

         Each Shareholder, severally but not jointly, represents and warrants to
NEON as follows:

         3.1 Ownership of Shares. Such Shareholder is the sole legal and
beneficial owner of the Shares designated as being owned by such Shareholder
opposite such Shareholder's name in



                                      -24-
<PAGE>   29

Schedule 3.1. Such Shares are not subject to any Liens or to any rights of first
refusal of any kind, and such Shareholder has not granted any rights to purchase
such Shares to any other person or entity. Such Shareholder has the sole right
to transfer such Shares to NEON. Such Shares constitute all of the Company Share
Capital owned, beneficially or of record, by such Shareholder, and such
Shareholder has no other rights to acquire Company Share Capital. Upon payment
of the Purchase Price in the manner set forth in Section 1.2, the Shareholders
will transfer to NEON and its designee good title to all of the Shares of the
Company, subject to no Liens retained, granted or permitted by such Shareholder
or the Company (except for the Memorandum and Articles of Association as to the
Company).

         3.2 Tax Matters. Such Shareholder has had an opportunity to review with
its own tax advisors the tax consequences to such Shareholder of the Acquisition
and the transactions contemplated by this Agreement. Such Shareholder
understands that it must rely solely on its advisors and not on any statements
or representations by NEON, the Company or any of their agents. Such Shareholder
understands that it (and not NEON or the Company) shall be responsible for its
own tax liability that may arise as a result of the Acquisition or the
transactions contemplated by this Agreement.

         3.3 Absence of Claims by the Shareholders. Such Shareholder does not
have any present claim against the Company and does not have knowledge of the
basis for any future claim against the Company whether, contingent or
unconditional, fixed or variable under any contract or on any other legal basis
whatsoever whether in the capacity as a shareholder, a director, or an officer
of the Company or otherwise.

         3.4 Authority. Such Shareholder has the legal capacity to enter into
this Agreement and the Shareholders Agreement in the form attached hereto as
Exhibit C and to consummate the transactions contemplated hereby and thereby,
and no further action is required on the part of such Shareholder to execute
this Agreement and the Shareholders Agreement. This Agreement and the
Shareholders Agreement have been duly executed and delivered by such Shareholder
and, assuming the due authorization, execution and delivery by the other parties
thereto, constitute the valid and binding obligations of each such Shareholder,
enforceable in accordance with their terms, except as such enforceability may be
limited by principles of public policy and subject to the laws of general
application relating to bankruptcy, insolvency and the relief of debtors and to
rules of law governing specific performance, injunctive relief or other
equitable remedies.

         3.5 No Conflict. The execution and delivery by such Shareholder of this
Agreement and the Shareholders Agreement and the consummation of the
transactions contemplated hereby and thereby will not conflict with (ii) any
mortgage, indenture, lease, material contract or other material agreement or
instrument, permit, concession, franchise or license to which such Shareholder
or any of its properties or assets are subject (a "Shareholder Conflict"), or
(iii) any judgment, order, decree, statute, law, ordinance, rule or regulation
applicable to such Shareholder or its properties or assets.



                                      -25-
<PAGE>   30

         3.6 Consents. No consent, waiver, approval, order or authorization of,
or registration, declaration or filing with, any Governmental Entity or any
third party (so as not to trigger any Shareholder Conflict), is required by or
with respect to such Shareholder in connection with the execution and delivery
of this Agreement or the Shareholders Agreement or the consummation of the
transactions contemplated hereby or thereby except for such consents, waivers,
approvals, orders, authorizations, registrations, declarations and filings as
may be required under applicable securities laws thereby.

         3.7 Unregistered Shares. Shareholder understands that the NEON Common
Stock being issued pursuant to this Agreement will not be registered under the
Securities Act of 1933, as amended, on the basis that the issuance of securities
hereunder is exempt from registration under said Act pursuant to Regulation S
and section 4(2) and/or Rule 506 thereof, and that NEON's reliance on such
exemption is based on Shareholder's representations set forth in the Stockholder
Agreement.


                                   ARTICLE IV

                     REPRESENTATIONS AND WARRANTIES OF NEON

         NEON hereby represents and warrants to the Company and each of the
Shareholders as follows:

         4.1 Organization, Standing and Power. NEON is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Delaware. NEON has the corporate power to own its properties and to carry on its
business as now being conducted and is duly qualified to do business and is in
good standing as a foreign corporation in each jurisdiction in which the failure
to be so qualified would have a material adverse effect on NEON as a whole.

         4.2 Authority. NEON has all requisite corporate power and authority to
enter into this Agreement and the exhibits attached hereto to which it is a
party (the "NEON Related Agreements") and to consummate the transactions
contemplated hereby and thereby. The execution and delivery of this Agreement
and NEON Related Agreements and the consummation of the transactions
contemplated hereby and thereby have been duly authorized by all necessary
corporate action on the part of NEON. Each of this Agreement and NEON Related
Agreements has been duly executed and delivered by NEON and constitutes the
valid and binding obligations of NEON, enforceable in accordance with its terms
except (i) as limited by applicable bankruptcy, insolvency, reorganization,
moratorium and other laws of general application affecting enforcement of
creditors' rights generally and (ii) as limited by laws relating to the
availability of specific performance, injunctive relief or other equitable
remedies.

         4.3 Capital Structure. The authorized stock of NEON consists of
45,000,000 shares of Common Stock, of which 30,333,778 shares were issued and
outstanding as of December 31, 1998, and 2,000,000 shares of Preferred Stock,
none of which is issued or outstanding. No shares of NEON



                                      -26-
<PAGE>   31

Common Stock were held by NEON in its treasury, and no shares of NEON Preferred
Stock were outstanding. All the outstanding shares of NEON Common Stock are
validly issued, fully paid, nonassessable and free of preemptive rights. The
shares of NEON Common Stock issuable in connection with the Acquisition have
been duly authorized and reserved for issuance and, when issued in accordance
with the terms of this Agreement, will be validly issued, fully paid,
nonassessable and free of preemptive rights.

         4.4 SEC Documents; NEON Financial Statements. NEON has furnished or
made available to the Company and the Shareholders true and complete copies of
all reports or registration statements filed by it with the Securities and
Exchange Commission ("SEC") under the Securities Exchange Act of 1934, as
amended (the "Exchange Act") for all periods since January 1, 1998, all in the
form so filed (all of the foregoing being collectively referred to as the "SEC
Documents"). As of their respective filing dates, the SEC Documents complied in
all material respects with the requirements of the Securities Act of 1933, as
amended (the "Securities Act") or the Exchange Act, as the case may be, and none
of the SEC Documents contained any untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary to
make the statements made therein, in light of the circumstances in which they
were made, not misleading, except to the extent corrected by a document
subsequently filed with the SEC. The financial statements of NEON, including the
notes thereto, included in the SEC Documents (the "NEON Financial Statements")
comply as to form in all material respects with applicable accounting
requirements and with the published rules and regulations of the SEC with
respect thereto, have been prepared in accordance with GAAP consistently applied
(except as may be indicated in the notes thereto or, in the case of unaudited
statements, as permitted by Form 10-Q of the SEC) and present fairly the
consolidated financial position of NEON at the dates thereof and the
consolidated results of its operations and cash flows for the periods then ended
(subject, in the case of unaudited statements, to normal audit adjustments).

         4.5 Litigation. There is no action, suit proceeding, claim, arbitration
or investigation pending, or as to which NEON has received any notice of
assertion against NEON, which in any manner challenges or seeks to prevent,
enjoin, alter or materially delay any of the transactions contemplated by this
Agreement.


                                   ARTICLE V

effectuation of the terms and conditions of this Agreement and the transactions
contemplated hereby shall be the obligation of the respective party incurring
such fees and expenses,



                                      -27-
<PAGE>   32

except for stamp duty. NEON agrees to bear all stamp duty payable or assessed in
connection with this agreement and the transfer of shares to NEON.

         5.2 Public Disclosure. Unless otherwise required by law, or by the
rules and regulations of the SEC or Nasdaq Stock Market, no disclosure (whether
or not in response to an inquiry) of the subject matter of this Agreement shall
be made by any party hereto without the prior approval of NEON.

         5.3 Additional Documents and Further Assurances. Each party hereto, at
the request of another party hereto, shall execute and deliver such other
instruments and do and perform such other acts and things as may be necessary or
desirable for effecting completely the consummation of the Closing and the
transactions contemplated hereby.


                                   ARTICLE VI

        SURVIVAL OF REPRESENTATIONS AND WARRANTIES; INDEMNITY AND ESCROW

         6.1 Survival of Representations and Warranties. The Shareholders' and
NEON's representations and warranties in this Agreement or in any instrument
delivered pursuant to this Agreement shall survive the Closing and shall
terminate on the first anniversary of the Closing (the "Expiration Date");
provided, however, that (i) the representations and warranties and covenants of
the Shareholders relating or pertaining to any Tax or Returns related to such
Tax set forth in Section 2.10 hereof, shall survive until the expiration of all
applicable statutes of limitations, or extensions thereof, governing each Tax or
Returns related to such Tax and (ii) the representations and warranties of the
Shareholders set forth in Section 2.3 and Article III hereof shall survive the
Closing and shall terminate on the fourth anniversary of the Closing. Each
shareholder, jointly and severally, shall indemnify and hold harmless NEON and
its affiliates for any Loss (as defined in the Escrow Agreement) incurred by
NEON, its officers, directors or affiliates, related to or arising, directly or
indirectly, out of any breach of the representations and warranties set forth in
Sections 2.10, 2.3 and Article III of this Agreement.

         6.2 Indemnity and Escrow Agreement. At the Closing each Shareholder
will be deemed to have received and consented to the deposit with the Escrow
Agent of the Escrow Cash and the Escrow Shares (plus any additional shares as
may be issued upon any stock split, stock dividend or recapitalization effected
by NEON after the Closing) pursuant to the terms of the Escrow Agreement
attached hereto as Exhibit B, without any act required on the part of the
Shareholders. At the Closing, the Escrow Cash and the Escrow Shares, without any
act required on the part of the Shareholders, are being deposited with the
Escrow Agent, such deposit to constitute the Escrow Fund to be governed by the
terms set forth in the Escrow Agreement and at NEON's cost and expense. The
Escrow Fund and the related indemnification obligations of the Shareholders
shall be governed by the terms of the Escrow Agreement.

                          SHARE ACQUISITION AGREEMENT

         This SHARE ACQUISITION AGREEMENT (the "Agreement") is made and entered
into as of April 15, 1999 by and among New Era of Networks, Inc., a Delaware
corporation ("NEON"), Franz Koepper (the "Holding Shareholder") as the sole
shareholders of Koepper Holdings AG ("KH"), and the shareholders (the "SLI
Shareholders," and, along with the Holding Shareholder, the "Shareholders") set
forth on Schedule 1.1 attached hereto of SLI INTERNATIONAL AG, a Swiss
corporation incorporated in the Canton of Thurgau as the holding company of SLI
Consulting AG (Switzerland) (additionally, SLI Systemhaus AG (Switzerland) is a
50% owned subsidiary of SLI Consulting AG), SLI Consulting Inc. (United
States), SLI Consulting Ltd. (United Kingdom), SLI Consulting SDN BHD
(Malaysia) (additionally, SLI Consulting Pte. Ltd. (Singapore) and SLI
Consulting Limited (Hong Kong) are both wholly-owned subsidiaries of SLI
Consulting SDN BHD), (hereafter "SLI," and, together with the other companies
listed above, the "Company"), and, with respect to Article VIII, Franz Koepper
(in his capacity as the "Shareholder Representative"). All references to the
"Shareholders" shall be deemed to include both the SLI Shareholders and the
Holding Shareholder unless otherwise indicated. All references to "the Company"
shall include SLI and all of the other companies listed above unless otherwise
indicated.

                                    RECITALS

         A. The SLI Shareholders and KH own all of the issued and outstanding
capital stock of SLI and the Holding Shareholder owns all of the issued and
outstanding capital stock of KH. NEON desires to acquire all of the issued and
outstanding capital stock of SLI owned or held of record or to be owned or held
of record by the Shareholders and all of the issued and outstanding capital
stock of KH owned by the Holding Shareholder (together the "Acquisition") such
that upon consummation of the acquisition NEON will own (i) all of the issued
and outstanding capital stock of the Company owned by the Shareholders, and
(ii) all of the issued and outstanding capital stock of KH owned by the Holding
Shareholder.

         B. The Shareholders desire to sell all of the capital stock of SLI
owned or held of record or to be owned or held of record by them to NEON, and
the Holding Shareholder desires to sell all of the capital stock of KH owned by
him to NEON, upon the terms and subject to the conditions set forth herein.

         C. As an inducement for NEON to consummate the Acquisition, the
Shareholders agree to make certain representations, warranties, covenants and
other agreements in connection with the Acquisition.

         D. Ten percent (10%) of the consideration payable by NEON in
connection with the Acquisition shall be placed in escrow by NEON for the
purposes of satisfying damages, losses, expenses and other similar charges that
result from breaches of representations, warranties and




<PAGE>   7

covenants and shall be subject to an Escrow Agreement in substantially the form
attached hereto as Exhibit C.

         E. As an inducement for NEON to enter into this Agreement and to
consummate the Acquisition, Franz Koepper has agreed to enter into a
Non-Competition Agreement of even date herewith, in substantially the form
attached hereto as Exhibit A, which Non-Competition Agreements shall be
effective only upon the closing of the Acquisition.

         NOW, THEREFORE, in consideration of the covenants, promises and
representations set forth herein, and for other good and valuable
consideration, the parties agree as follows:


<PAGE>   8


                                   ARTICLE I

                       PURCHASE AND SALE OF COMPANY STOCK

         1.1 Purchase and Sale. At the Closing (as defined in Section 1.3) and
subject to and upon the terms and conditions of this Agreement:

                  (a) NEON shall purchase from each Shareholder and each
Shareholder shall sell, convey, transfer, assign and deliver to NEON, free and
clear of all liens, encumbrances or other defects of title, all of the issued
and outstanding shares of capital stock of the Company now beneficially owned
or held of record and to be beneficially owned or held of record by each
Shareholder at the Closing (the "SLI Shares"), including all property or rights
issued by the Company with respect to the SLI Shares. The name and address of
the Shareholders and the number of such SLI Shares being sold by the
Shareholders pursuant hereto are set forth in Schedule 1.1 attached hereto.

                  (b) NEON shall purchase from the Holding Shareholder and the
Holding Shareholder shall sell, convey, transfer, assign and deliver to NEON,
free and clear of all liens, encumbrances or other defects of title, all of the
issued and outstanding shares of capital stock of KH now beneficially owned or
held of record by the Holding Shareholder at the Closing (the "KH Shares"),
including all property or rights issued by KH with respect to the KH Shares.
The SLI Shares and KH Shares are sometimes collectively referred to herein as
the "Shares".

         1.2 Consideration.

                  (a) Subject to the terms and conditions of this Agreement, on
the Closing Date, in consideration of the sale, transfer and delivery of all of
each Shareholder's right, title and interest in and to the Company Stock to
NEON, and all of the Holding Shareholder's right, title and interest in and to
the KH Shares to NEON, NEON shall (i) pay to the SLI Shareholders and the
Holding Shareholder cash in the aggregate amount of $16.5 million (the "Cash
Consideration"), and (ii) issue to the SLI Shareholders and the Holding
Shareholder, as set forth below, that number of shares of Common Stock of NEON
valued at $5.5 million at the Closing based on the lower of (i) the average
closing sale price of a share of NEON Common Stock, as reported on the Nasdaq
National Market, for the twenty (20) most recent trading days ending on the
third trading day immediately preceding the Closing Date and (ii) the average
closing sale price of a share of NEON Common Stock, as reported on the Nasdaq
National Market, for the five (5) most recent trading days ending on the third







                                      -2-
<PAGE>   9

trading day immediately preceding the Closing Date (the "Stock Consideration"
and, together with the Cash Consideration, the "Purchase Price"); provided,
however, that NEON shall withhold $1.65 million of Cash Consideration (the
"Escrow Cash"), together with that number of shares of Common Stock of NEON
valued at $550,000 at the Closing based on the lower of (i) the average closing
sale price of a share of NEON Common Stock, as reported on the Nasdaq National
Market, for the twenty (20) most recent trading days ending on the third
trading day immediately preceding the Closing Date and (ii) the average closing
sale price of a share of NEON Common Stock, as reported on the Nasdaq National
Market, for the five (5) most recent trading days ending on the third trading
day immediately preceding the Closing Date (the "Escrow Shares," and, together
with the Escrow Cash, the "Escrow Amount") into an escrow account established
in the joint names of NEON and the Shareholder Representative, for deposit (the
"Escrow Fund") as collateral for the indemnification obligations of the
Shareholders under Article VIII hereof pursuant to the provisions of an escrow
agreement substantially in the form of Exhibit C attached hereto (the "Escrow
Agreement") to be entered into at the Closing by and among NEON, the
Shareholder Representative and Credit Suisse Trust (the "Escrow Agent").
Schedule 1.1 sets forth the pro rata allocation of the consideration among the
SLI Shareholders and the Holding Shareholder (including the allocation of the
Escrow Fund and the Incentive Shares, if any, among the SLI Shareholders and
the Holding Shareholder).

                  (b) In addition, NEON shall issue to the Shareholders up to
that number of shares of Common Stock of NEON valued at $3 million at the
Incentive Share Issuance Date and at Subsequent Incentive Share Issuance Dates
based on the lower of (i) the average closing sale price of a share of NEON
Common Stock, as reported on the Nasdaq National Market, for the twenty (20)
most recent trading days ending on the third day immediately preceding the
Closing Date and (ii) the average closing sale price as reported on the Nasdaq
National Market for the five (5) most recent trading days ending on the third
trading date immediately preceding the Closing as incentive consideration (the
"Incentive Shares"), subject to the following provisions:

                           (i) As used herein, "Incentive Product Revenue"
shall mean the net revenues recognized by NEON from the license of NEON's
software products where one or more SLI employees materially participated in
the sale and/or implementation services of such NEON software product. The
Incentive Product Revenue shall be determined in accordance with U.S. GAAP and
SOP 97-2 and NEON's revenue recognition policies (as determined by NEON's
independent auditors, Arthur Andersen LLP, whose determination shall be final
and conclusive).

                           (ii) NEON shall issue Incentive Shares having a
value of $1.5 million, if any, within thirty (30) days after the Incentive
Product Revenue reaches an aggregate of $5 million (the "Incentive Share
Issuance Date"), but only in the event that the Incentive Product Revenue
reaches an aggregate of $5 million on or before June 30, 2000. Additional
Incentive Shares in an amount valued at $1.00 shall be issued for each $3.00 of
Incentive Product Revenue in excess of $5 million attained prior to June 30,
2000. The issuance of additional Incentive Shares shall be evaluated quarterly
after Incentive Product Revenues have surpassed $5 million and the additional
Incentive Shares, if any, shall be issued within 30 days following the end of
each such quarter (the "Subsequent Incentive Share Issuance Dates"). The
Incentive Shares, if any, shall be issued to the Shareholders pro rata in
accordance with Schedule 1.1.

                           (iii) At the time of issuance of Incentive Shares,
if any, pursuant to this Section 1.2, NEON shall provide to each Shareholder a
report containing a statement of the Incentive Product Revenue and the number
of Incentive Shares earned pursuant to this Section 1.2, and the basis of such
determination.

<PAGE>   10

                           (iv) NEON shall maintain adequate books and records
relating to the calculation of the Incentive Product Revenues through June 30,
2000 for a period of one (1) year following the June 30, 2000 date and the
Shareholders shall have the right to inspect, audit and receive copies of such
information during normal business hours. The Shareholders shall be required to
bear the reasonable fees and costs of such audit unless the results of the
audit indicate an underpayment by NEON equal to or in excess of 10% of the
payment due, in which case NEON shall bear the reasonable fees and costs of the
audit. NEON shall be required to make any underpayments shown by the audit. The
Shareholders shall be required to pay to NEON any overpayments shown by the
audit. In the event of any dispute, the determination of such firm shall be
final and binding on all parties.

                  (c) The shares of NEON Common Stock (including any Incentive
Shares) issuable hereunder shall be subject to a Shareholder Agreement
substantially in the form of Exhibit B attached hereto (the "Shareholder
Agreement") to be executed by and between each Shareholder and NEON.

                  (d) No fraction of a share of NEON Common Stock will be
issued, but, after aggregating all fractional shares of NEON Common Stock to be
received by such holder, such number shall be rounded to the nearest whole
number of shares of NEON Common Stock.

         1.3  Closing.

                  (a) The closing of the Acquisition (the "Closing") will take
place at or about 9:00 a.m. Denver, Colorado time on or before May 16, 1999,
provided that satisfaction or waiver of the conditions set forth in Article VII

Walzmuhlestrausse 60, Frauenfeld, Switzerland 8501, unless another time or
place is agreed to in writing by NEON and the Shareholders. The date upon which
the Closing actually occurs is herein referred to as the "Closing Date."

                  (b) At the Closing, the Company and each Shareholder and the
Holding Shareholder shall deliver or cause to be delivered to NEON the

or as may be reasonably requested by any party in order to consummate the

depreciation or capital allowances) shall be apportioned on a per diem basis.
Such Returns shall be made available to the Shareholders no less than 21
calendar days prior to the filing thereof with the appropriate governmental
authority for review by the Shareholders. From and after the Closing Date, NEON
and the Company, on the one hand, and the Shareholders, on the other hand,

        SURVIVAL OF REPRESENTATIONS AND WARRANTIES; INDEMNITY AND ESCROW

         8.1 Survival of Representations and Warranties; Indemnity. The
representations and warranties of the Shareholders in this Agreement or in any
instrument delivered pursuant to this Agreement shall survive the Closing and
shall terminate twelve (12) months after the Closing (the "Expiration Date");
provided, however, that (i) the representations and warranties and covenants
relating or pertaining to any Tax or Returns related to such Tax set forth in
Section 2.10, Section 2.29(c) and Section 6.7 hereof, shall survive until the
expiration of all applicable statutes of limitations, or extensions thereof,
governing each Tax or Returns related to such Tax and (ii) the representations
and warranties set forth in Section 2.3, Section 2.29(a) and Article III hereof
shall survive the Closing and continue for a period of four (4) years after the
Closing, except for Section 3.7, which shall survive until the last issuance of
Incentive Stock pursuant to Section 1.2(b). The Shareholders shall, jointly and
severally in the case of the Holding Shareholder and severally in the case of
the other Shareholders, except as to the Escrow Amount, in which case liability
shall be joint and several as to all of the Shareholders, indemnify and hold
harmless NEON and its affiliates for any claims, losses, liabilities, damages,
deficiencies, costs and expenses, including reasonable attorneys' fees and
expenses, and expenses of investigation and defense (hereinafter individually a
"Loss" and collectively "Losses"), incurred by NEON, its officers, directors,
or affiliates, related to or arising out of any inaccuracy or breach of the
representations, warranties, and covenants specified in clauses (i) and (ii)
hereof. Such indemnity shall be limited to a maximum of $16.5 million for the
Holding Shareholder and for the other Shareholders such indemnity shall be
limited to a maximum of their portion of the Shareholder consideration set
forth in Section 1.2. NEON's representations and warranties contained in this
Agreement shall terminate at the Closing.

         8.2 Indemnity; Escrow Arrangements.

                  (a) Escrow Fund. At the Closing each Shareholder will be
deemed to have received and consented to the deposit with the Escrow Agent of
the Escrow Amount pursuant to the Escrow Agreement attached hereto as Exhibit
C, without any act required on the part of the Shareholders. As soon as
practicable after the Closing, the Escrow Amount, without any act





                                     -31-
<PAGE>   38

required on the part of the Shareholders, will be deposited with the Escrow
Agent into an interest-bearing account, such deposit to constitute the Escrow
Fund to be governed by the terms set forth herein and at NEON's cost and
expense. The Shareholders shall bear the tax for all interest attributable to
the Escrow Account. The Escrow Fund shall be comprised entirely of the Escrow
Amount. The Escrow Fund is available to indemnify and compensate NEON and its
affiliates for any Losses incurred by NEON, its officers, directors, or
affiliates directly or indirectly as a result of any inaccuracy or breach of a
representation or warranty or covenant of the Shareholders, contained in
Articles II and III and VI herein, or any failure by the Shareholders to
perform or comply with any covenant contained herein. NEON shall not be
entitled to recover any amount from the Escrow Fund until its Losses exceed
$50,000 in the aggregate, at which time NEON may recover all of its Losses
including the first $50,000; provided, however, that any Losses incurred by
NEON relating to any representation, warranty or covenant related to Taxes set
forth in Sections 2.10 and 6.7 or to Section 2.3 or Article III hereof shall
not be subject to such minimum amount. NEON and the Shareholders each
acknowledge that such Losses, if any, would relate to unasserted contingent
liabilities existing at the Closing, which if resolved at the Closing would
have led to a reduction in the aggregate Purchase Price.

                  (b) Escrow Period; Distribution. Subject to the following
requirements, the Escrow Fund shall be in existence immediately following the
Closing and shall terminate on the Expiration Date (the "Escrow Period");
provided that the Escrow Period shall not terminate with respect to such amount
(or some portion thereof), that together with the aggregate amount remaining in
the Escrow Fund is necessary in the reasonable judgment of NEON (subject to
such reduction as may be determined by arbitration as provided in Section
8.2(f) hereof in the event of the objection of the Shareholder Representative
as provided in Section 8.2(e) hereof) to satisfy any unsatisfied claims
concerning facts and circumstances existing prior to the termination of the
Expiration Date during such Escrow Period. As soon as all such claims have been
resolved, the parties shall transfer to the Shareholders the remaining portion
of the Escrow Fund not required to satisfy such claims.

                  (c) Protection of the Escrow Fund. The Shareholder
Representatives and NEON jointly, and/or their appointed representatives, shall
be the only individuals who have the authority to authorize withdrawals from
the account.

                  (d) Claims Upon Escrow Fund. In the event that NEON suffers
any Losses, it shall deliver to the Shareholder Representative at any time on
or before the last day of the Escrow Period a certificate signed by any officer
of NEON: (A) stating that NEON has paid or properly accrued or reasonably
anticipates that it will have to pay or accrue Losses, and (B) specifying in
reasonable detail the individual items of Losses included in the amount so
stated, the date each such item was paid or properly accrued, or the basis for
such anticipated liability, and the nature of the misrepresentation, breach of
warranty or covenant to which such item is related. NEON and the Shareholder
Representative shall then, subject to the provisions of Section 8.2(e) and
Section 8.2(f) hereof, promptly transfer or cause the transfer agent of NEON
Company Stock to transfer to NEON out of the Escrow Fund an aggregate amount
equal to such Losses. Such payments of Escrow Amount from the Escrow Fund will
be made pro rata in proportion to the Shareholders original





                                     -32-

contributions to the Escrow Fund. Withdrawals shall be comprised of 75% Escrow
Cash and 25% Escrow Shares.

                  (e) For the purposes of determining the number of shares of
NEON Company Stock to be delivered to NEON out of the Escrow Fund pursuant to
Section 8.2 hereof, the shares of NEON Company Stock shall be valued at the
average closing price of NEON's Company Stock for the twenty (20) consecutive
trading days ending on the third trading day immediately prior to the Closing
Date, as reported on the Nasdaq National Market.

                  (f) Objections to Claims In the event that NEON and the
Shareholder Representative cannot agree as to the propriety of a withdrawal
from the account the matter will be decided according to the arbitration
provisions set forth in Section 8.2(g) below.

                  (g) Resolution of Conflicts; Arbitration.

                           (i) In case the Shareholder Representative shall
object to any claim or claims made against the Escrow Fund by NEON, the
Shareholder Representative and NEON shall attempt in good faith to agree upon
the rights of the respective parties with respect to each of such claims.

                           (ii) If no such agreement can be reached after good
faith negotiation, either NEON or the Shareholder Representative may demand
arbitration of the matter unless the amount of the damage or loss is at issue
in pending litigation with a third party, in which event arbitration shall not
be commenced until such amount is ascertained or both parties agree to
arbitration; and in either such event the matter shall be settled by
arbitration conducted by three arbitrators. NEON and the Shareholder
Representative shall each select one arbitrator, and the two arbitrators so
selected shall select a third arbitrator. The English language shall be used
for the arbitration. The arbitrators shall set a limited time period and
establish procedures designed to reduce the cost and time for discovery while
allowing the parties an opportunity, adequate in the sole judgment of the
arbitrators, to discover relevant information from the opposing parties about
the subject matter of the dispute. The arbitrators shall rule upon motions to
compel or limit discovery and shall have the authority to impose sanctions,
including attorneys' fees and costs, to the same extent as a court of competent
law or equity, should the arbitrators determine that discovery was sought
without substantial justification or that discovery was refused or objected to
without substantial justification. The decision of a majority of the three
arbitrators as to the validity and amount of any claim of NEON shall be binding
and conclusive upon the parties to this Agreement. Such decision shall be
written and shall be supported by written findings of fact and conclusions
which shall set forth the award, judgment, decree or order awarded by the
arbitrators.

                           (iii) Judgment upon any award rendered by the
arbitrators may be entered in any court having jurisdiction. Any such
arbitration shall be held in Geneva, Switzerland, using the English language
and either U.S. federal law for securities and tax issues or Delaware state law
for all other issues, whichever is more appropriate. The arbitration shall be
conducted under the rules then in effect of the Rules of Arbitration of the
Chamber of Commerce and Industry of Geneva. For purposes of this Section
8.2(f), in any arbitration hereunder in which any claim or the amount





                                     -33-
<PAGE>   40

thereof stated in the Officer's Certificate is at issue, NEON shall be deemed
to be the Prevailing Party in the event that the arbitrators award NEON an
amount equal to at least the sum of one half (1/2) of the disputed amount plus
any amounts not in dispute; otherwise, the Shareholders as represented by the
Shareholder Representative shall be deemed to be the Prevailing Party. If NEON
acts as the Plaintiff in an arbitration, NEON shall pay the first $100,000 of
the costs and expenses of the arbitrators in such action. If the Shareholders
act as the Plaintiff in an arbitration, the Shareholders shall pay the first
$100,000 of the costs and expenses of the arbitration in such action. If NEON
acts as the Plaintiff in an arbitration, NEON shall pay the first $50,000 of
the Shareholders' attorneys fees and attorneys expenses. The non-prevailing
party in any arbitration shall reimburse the prevailing party for the
prevailing party's attorneys fees and attorneys expenses, such reimbursement
not to exceed $100,000. In addition, if NEON is the prevailing party, the
Shareholders shall reimburse NEON for any amount of Shareholder's attorneys
fees and attorney expenses previously paid by NEON.

                  (h)  Shareholder Representative of the Shareholders; Power of
Attorney.

                           (i) Upon the Closing, and without further act of any
Shareholders, Franz Koepper shall be appointed as agent and attorney-in-fact
(the "Shareholder Representative") for each Shareholder, for and on behalf of
the Shareholders, to give and receive notices and communications, to authorize
delivery to NEON of Escrow Shares or Escrow Cash from the Escrow Fund in
satisfaction of claims by NEON, to object to such deliveries, to agree to,
negotiate, enter into settlements and compromises of, and demand arbitration
and comply with orders of courts and awards of arbitrators with respect to such
claims, and to take all actions necessary or appropriate in the judgment of the
Shareholder Representative for the accomplishment of the foregoing. Such agency
may be changed by a majority in interest of the Shareholders from time to time
upon not less than thirty (30) days prior written notice to NEON; provided that
the Shareholder Representative may not be removed unless holders of a
two-thirds interest of the Escrow Fund agree to such removal and to the
identity of the substituted agent. Any vacancy in the position of the
Shareholder Representative may be filled by approval of the holders of a
majority in interest of the Escrow Fund. No bond shall be required of the
Shareholder Representative, and the Shareholder Representative shall not
receive compensation for his or her services. Notices or communications to or
from the Shareholder Representative shall constitute notice to or from each of
the Shareholders.

                           (ii) The Shareholder Representative shall not be
liable for any act done or omitted hereunder as Shareholder Representative
while acting in a manner he or she believes in good faith to be in the best
interests of the Company. The Shareholders on whose behalf the Escrow Amount
were contributed to the Escrow Fund shall severally indemnify the Shareholder
Representative and hold the Shareholder Representative harmless against any
loss, liability or expense incurred without gross negligence or bad faith on
the part of the Shareholder Representative and arising out of or in connection
with the acceptance or administration of the Shareholder Representative's
duties hereunder, including the reasonable fees and expenses of any legal
counsel retained by the Shareholder Representative.

<PAGE>   41

                  (i) Actions of the Shareholder Representative. A decision,
act, consent or instruction of the Shareholder Representative shall constitute
a decision of all the Shareholders for whom a portion of the Escrow Amount
otherwise issuable to them are deposited in the Escrow Fund and shall be final,
binding and conclusive upon each of such Shareholders, and the Escrow Agent and
NEON may rely upon any such decision, act, consent or instruction of the
Shareholder Representative as being the decision, act, consent or instruction
of each every such Shareholder of the Company. NEON is hereby relieved from any
liability to any person for any acts done by them in accordance with any
decision, act, consent or instruction of the Shareholder Representative.

                  (j) Third-Party Claims. In the event NEON becomes aware of a
third-party claim that NEON believes may result in a demand against the Escrow
Fund, NEON shall promptly notify the Shareholder Representative of such claim
in accordance with Section 8.2(d), and the Shareholder Representative, as
representative of the Shareholders, shall be entitled, at his expense, to
participate in any defense of such claim. NEON shall have the right in its sole
discretion to control the defense of all such claims and to settle any such
claim; provided, however, that no settlement of any such claim with third-party
claimants in excess of $100,000 in a single matter shall permit any claim
against the Escrow Fund, except with the consent of the Shareholder
Representative, which consent shall not be unreasonably withheld. In the event
that the Shareholder Representative has consented to any such settlement and
acknowledged that the claim is a valid claim against the Escrow Fund, the
Shareholder Representative shall be deemed to have agreed to the claim by NEON
against the Escrow Fund in an amount equal to such settlement.

                                  ARTICLE IX

                       TERMINATION, AMENDMENT AND WAIVER

                  (a) by mutual agreement of the Shareholders and NEON;

not occurred by May 16, 1999; (ii) there shall be a final nonappealable order
of a court in effect preventing consummation of the Acquisition; or (iii) there
shall be any statute, rule, regulation or order enacted, promulgated or issued
or deemed applicable to the Closing by any Governmental Entity that would make

                  (c) by NEON if there shall be any action taken, or any
statute, rule, regulation or order enacted, promulgated or issued or deemed
applicable to the Acquisition by any Governmental Entity, which would: (i)

Company or (ii) compel NEON or the Company to dispose of or hold separate all

<PAGE>   42

                  (d) by NEON, if it is not in material breach of its
obligations under this Agreement, and there has been a material breach of any
representation, warranty, covenant or agreement contained in this Agreement on
the part of the Company or Shareholders and such breach has not been cured
within five (5) calendar days after written notice to the Company and the
Shareholders; provided, however, that, no cure period shall be required for a
breach that by its nature cannot be cured;

under this Agreement and there has been a material breach of any
representation, warranty, covenant or agreement contained in this Agreement on
the part of NEON and such breach has not been cured within five (5) calendar
days after written notice to NEON; provided, however, that no cure period shall
be required for a breach which by its nature cannot be cured;

         Where action is taken to terminate this Agreement pursuant to this
Section 9.1, it shall be sufficient for such action to be authorized by the
Board of Directors (as applicable) of the party taking such action.

         9.2 Effect of Termination. In the event of termination of this
Agreement, at any time prior to Closing, as provided in Section 9.1, this
Agreement shall forthwith become void and there shall be no liability or
obligation on the part of NEON or the Company, or their respective officers,
directors or shareholders, provided that the breaching party shall remain
liable for all costs or expenses, including legal and financial services,
incurred by the non-breaching party relating to this Agreement prior to its
termination; and provided further that the provisions of Sections 6.2, 6.3 and
6.4, Article X and this Section 9.2 shall remain in full force and effect and

representations and warranties made to such party contained herein or in any
document delivered pursuant hereto, and (iii) waive compliance with any of the

party.

with its obligations under Sections 5.2 or 6.10 hereof, then the Company shall
promptly pay to NEON, as compensation to NEON for the anticipated transaction
expenses and opportunity costs of NEON, the sum of $750,000.

         RE:      REGISTRATION STATEMENT ON FORM S-3

Ladies and Gentlemen:

         We have examined the Registration Statement on Form S-3 to be filed by
you with the Securities and Exchange Commission on or about the date hereof (the
"Registration Statement") in connection with the registration under the
Securities Act of 1933, as amended, of up to 1,515,123 shares of your Common
Stock (the "Shares"). All of the Shares are issued and outstanding and may be
offered for sale for the benefit of the selling stockholders named in the
Registration Statement. We understand that the Shares are to be sold from time
to time in the over-the-counter-market at prevailing prices or as otherwise
described in the Registration Statement. As your legal counsel, we have also
examined the proceedings taken by you in connection with the issuance of the
Shares.

         It is our opinion that the Shares are validly issued, fully paid and
non-assessable.

         We consent to the use of this opinion as an exhibit to the Registration
Statement and further consent to the use of our name wherever appearing in the
Registration Statement, including the Prospectus constituting a part thereof,
and any amendments thereto.

                                        Sincerely,
