         This is a public offering of a minimum of 861,923 and a maximum of
994,740 shares of common stock of Online System Services, Inc. The selling
shareholders identified in this prospectus are offering all of the shares to be

shares, however certain shares offered by this prospectus are issuable upon
the exercise of issued and outstanding transferable warrants of OSS. If these 
warrants are excerised in full and the exercise price is paid in cash rather
than by a surrender of a portion of the warrants being exercised (a cashless
exercise), OSS will receive proceeds of $3,234,900.

         The shares to be sold by the selling shareholders consist of 78,240
issued and outstanding shares of common stock and shares of common stock
issuable to them upon:

            - Their conversion of OSS' 10% Preferred Stock;
            - Their conversion of OSS' Series A Preferred Stock;
            - Their exercise of issued and outstanding transferable warrants of
              OSS exercisable at a price per share of $15.00;
            - Their exercise of issued and outstanding transferable warrants of
              OSS exercisable at a price per share of $16.33; or
            - Their exercise of issued and outstanding transferable warrants of
              OSS exercisable at a price per share of $5.71.
 
         The Nasdaq SmallCap Market lists the common stock under the symbol
"WEBB".



         INVESTING IN THE COMMON STOCK INCLUDES CERTAIN RISKS. YOU SHOULD NOT
PURCHASE THE COMMON STOCK UNLESS YOU CAN AFFORD TO LOSE YOUR ENTIRE INVESTMENT.
SEE "RISK FACTORS" BEGINNING ON PAGE 3 OF THIS PROSPECTUS.



         The shares may be offered and sold at various times by the selling
shareholders identified in this prospectus pursuant to rules promulgated by the
Securities and Exchange Commission. The selling shareholders will offer and sell
the shares at market prices prevailing at the time of sale or at negotiated
prices and may sell the shares to or through brokers or dealers. Because the
selling shareholders will offer and sell the shares at various times, OSS has
not included in this prospectus information about the price to the public of the
shares or the proceeds to the selling shareholders.

                                  THE COMPANY

         Online System Services, Inc. develops, markets and supports products
and services that enable individuals to create and manage their own Internet 
Web presence, create public or private online communities and manager their own
interactions. Our i2u foundation software provides users with the ability 
to create their own home pages using simple, on-screen templates, as well as 
integrated online communications, commerce and publishing tools. We have 
targeted the following market opportunities:

         -        i2u Community - Customized community and communication portals
                  or start pages for broadband (high bandwidth or high data
                  transmission capabilities) operators who provide Internet 
                  access.

         -        i2u Enterprise - Internet and Extranet services for 
                  businesses, associations and government institutions.

         -        i2u Education - Classroom applications for elementary and
                  secondary schools, including parent/teacher communications,
                  virtual campuses for colleges and universities and online 
                  classrooms for corporate training.

         -        i2u Financial Services - Online banking services for banks,
                  credit unions and other financial institutions.

         Our integrated i2u software permits the generation of Internet Web site
content by individual users, Internet service providers ("ISPs"), local merchant
and others. Personal user home pages, enhanced business Web pages, business
directories, community events, online discussion groups and forums and
programming guides can all be developed and updated by users. The i2u software
includes personal communication tools which facilitate user interaction and
community "groupware" which enables any group to create a public or private
community for personal interaction and information exchange.

         In order to gain market share and to create a foundation for future
content revenues, we have developed a suite of products, marketed under the i2u
brand, which provides broadband operators with our proprietary software, as well
as the equipment, training, systems and services required for the broadband 
operator to become fully operational Internet service provider. These products
and services are provided at minimal or no initial cost to the operator in 
in exchange for which we share in the revenues from Internet advertising and 
commerce and, if the operator utilizes our access products and services, 
Internet access.

         We have utilized the i2u foundation software to develop an online 
product designed for elementary and secondary schools which facilitates 
communications and information exchange among teachers, administrators, parents
and students. We have also developed "RE/MAX Mainstreet," a system designed to 
be RE/MAX International, Inc.'s primary communcation tool linking its real 
estate agents, management and approved suppliers worldwide and a 
state-of-the-art system for providing online banking services for Rockwell 
Federal Credit Union.

         As part of our product enhancement efforts, we have agreed to acquire
Durand Communications, Inc. ("DCI"), a developer and marketer of Internet 
"community" building tools and services which allow users to set up their own 
password-protected virtual communities. DCI's CommunityWare product is being 
integrated into the i2u suite of products and services. DCI has provided the
information regarding DCI included in this prospectus. See "Recent 
Developments--DCI Acquisition."

         Our strategies to achieve our growth objective include:

         -        Gaining early market share by offering the i2u Community 
                  products and services to broadband operators at minimal or no
                  initial cost in exchange for a larger share of the revenues
                  from Internet commerce and access;

         -        Continuing to expand the i2u suite of products and services;

         -        Leveraging the i2u platform software to develop products for
                  the development of online communities for specific industries
                  and markets;

         -        Aggregating subscribers of multiple online communities to 
                  develop unique channels of distribution for Internet products,
                  advertising and services; and

         -        Acquisitions; and 

         -        Developing strategic alliances.

         OSS was incorporated under the laws of the State of Colorado on
March 22, 1994. Our executive offices are located at 1800 Glenarm Place, Suite
700, Denver, Colorado 80202, telephone number (303) 296-9200.

                                  RISK FACTORS
                                        
         The common stock offered by this prospectus is highly speculative and
involves a high degree of risk. Before you purchase any common stock you should
carefully read this entire prospectus, and you should consider the following
risks and speculative factors. You should purchase common stock only if you can
afford the loss of your entire investment in the common stock.. You should also
be aware that certain statements set forth below are "forward-looking
statements" as defined in the Private Securities Litigation Reform Act of 1995.
Please refer to the "Special Note Regarding Forward-Looking Statements" on page
11 of this prospectus for more information.

RISKS RELATED TO BUSINESS OF OSS

         LIMITED OPERATING HISTORY; ACCUMULATED LOSSES. OSS was founded in March
1994, commenced sales in February 1995 and was in the development stage through
December 31, 1995. DCI was founded in 1993. Accordingly, we have only a limited
operating history upon which you can base your evaluation of our prospects, DCI
and us. In conducting your evaluation, you should consider our prospects,
including the prospects of DCI, in light of the risks, expenses and difficulties
frequently encountered by companies in their early stage of development,
particularly companies in new and rapidly evolving markets such as the Internet
market. These risks include our ability to respond to competitive developments,
our ability to continue to attract, retain and motivate qualified persons, and
our ability to continue to upgrade and commercialize our products and services.
There is no assurance that we will be successful in addressing these and other
risks. Economic and market conditions over which we have no control may also
significantly affect our business. We have incurred net losses since inception
totaling $13,158,897 through September 30, 1998. DCI has incurred net losses
since its formation totaling $8,061,004 through September 30, 1998.

         ADDITIONAL ANTICIPATED LOSSES. We currently intend to increase our
capital expenditures and operating expenses in order to expand the functionality
and performance of our i2u products and services, support additional subscribers
of our ISP customers in future markets, and market and provide our products and
services. In addition, we adopted a new pricing structure in the second quarter
of 1998 which will provide our i2u Community products and services to broadband
operators, including the equipment required for the operator to provide high-
speed Internet access to its subscribers, at little or no initial charge to the
operator in return for a percentage of the operator's future Internet access and
e-commerce transaction fees. This new pricing structure will increase our costs
and lower our revenues at the time that we sell our i2u products and services to
broadband operators. As a result of our increased capital expenditures and
operating expenses and our new pricing structure, we expect to incur additional
substantial operating and net losses for the balance of fiscal 1998 and for one
or more fiscal years thereafter.

         Furthermore, if we complete the DCI acquisition, we will incur
additional losses for the fiscal year in which the acquisition occurs (currently
anticipated to be in the first quarter of fiscal 1999). These losses will occur
because accounting rules require us to recognize as a loss in the fiscal period
in which the acquisition is consummated that portion of the purchase price for
DCI which we allocate to in-process research and development. We expect to
allocate approximately $500,000 to in-process research and development. In
addition, if the DCI acquisition is completed, we will record goodwill and other
intangible assets estimated to be approximately $12.5 million which we will
amortize over their estimated useful life of three years. There can be no
assurance that the acquisition of DCI will ever make a positive contribution to
our results of operations. The final determination of the value of consideration
issued by OSS and the liabilities assumed will be made at the effective time of
the DCI Merger. Accordingly, the determination of the total purchase price,
liabilities assumed and the allocations may change significantly from the
amounts reflected above. If we do not complete the DCI Merger, it is likely that
we would have to write-off the note receivable of $805,320 at September 30,
1998, which would increase our losses.

         INCREASED NEED FOR WORKING CAPITAL; ABILITY TO CONTINUE AS GOING
CONCERN. We believe that our present cash and cash equivalents and working
capital will be adequate to sustain operations only through the balance of
fiscal 1998. In addition, we expect the acquisition of DCI to increase our
monthly working capital needs by approximately $130,000 for at least the next
six months. We estimate that we will need to raise at least $8 million through
equity, debt or other external financing to fund proposed operations for fiscal
1999 and to pay DCI indebtedness which would be assumed as part of the DCI 
Merger. Our estimate of our working capital needs may change due to factors some
of which are outside of our control. As of the date of this prospectus, we have
entered into a letter of intent for the issuance of convertible preferred stock
which would raise approximately $4,5000,000 of additional net capital. However,
there is no assurance that we will be able to raise funds in amounts required or
upon acceptable terms. If we cannot raise funds when needed, we may be required
to curtail or scale back our operations. These actions could have a material
                                       3
<PAGE>
 
adverse effect on our business, financial condition, or results of operations.
In its report accompanying the audited financial statements for the years ended
December 31, 1997 and 1996, our auditor, Arthur Andersen LLP, expressed
substantial doubt about our ability to continue as a going concern.

         UNCERTAINTY OF FUTURE PROFITABILITY. Our ability to become profitable
in the future depends on the success of our i2u products and services in
generating revenues. This success will depend upon, among other things, the
willingness of subscribers of our broadband customers to pay the installation
costs of Internet service and monthly Internet access fees, both of which will
be set by our broadband customers. Furthermore, since we expect a significant
portion of our future revenues to be based on advertising and e-commerce
transactions conducted through our i2u products, this success will also depend
upon the extent to which consumers and businesses use our i2u products and
conduct e-commerce transactions and advertising utilizing our products. Our
pricing model assumes that our broadband customers will share with us a
percentage of their revenues generated by installation and Internet access fees
(if we provide the access capability) and a percentage of their revenues
generated by advertising and e-commerce conducted through our i2u products.
Because of the new and evolving nature of the Internet, we cannot predict
whether our pricing model will prove to be viable, whether demand for our
products and services will materialize at the prices we expect to be charged, 
or whether current or future pricing levels will be sustainable. Our ability to
generate future sales will be dependent on a number of factors, many of which
are beyond our control, including, among others, the success of broadband
operators in marketing Internet services to subscribers in their local areas,
the extent that users utilize our i2u products and conduct online e-commerce
transactions and the prices that the broadband operators set for Internet
services. Because of the foregoing factors, among others, we are unable to
forecast our revenues with any degree of accuracy. We may never become or remain
profitable.

         CABLE SYSTEM OPERATORS AFFILIATION WITH NATIONAL PROVIDERS. @Home
Corporation and RoadRunner (the "National Providers") offer high-speed Internet
access and related services to cable system operators. The National Providers
historically have focused their activities on larger markets because they
generally require cable system systems with two-way high speed data transmission
to fully implement their high-speed Internet access programs. Approximately 70%
of all cable system operators are currently affiliated with one of the National
Providers and this percentage could increase as a result of consolidations
within the cable industry. The terms of the agreements between the National
Providers and their affiliated cable operators prevent affiliated cable
operators from working with any person other than the National Providers to
provide high-speed Internet access. Although we have designed our i2u products
and services to be complementary to that of the National Providers, we have no
assurance from the National Providers that they will permit their affiliated
cable companies from working with us to provide high-speed Internet access in
markets in which the National Providers are not currently providing high speed
Internet access. If the National Providers prohibit us from providing high-speed
Internet access to these affiliated cable system providers, we would be able to
provide the high-speed Internet access portion of our i2u product and service
offering to only those broadband operators who are not affiliated with the
National Providers. This would significantly reduce the size of the domestic
market for our Internet access products and services. We do not believe that the
affiliation agreements between the affiliated cable system operators and the
National Providers limit our ability to partner with the affiliated cable system
operators to provide the local content portion of our i2u Community product and
services.

         NEW AND UNCERTAIN MARKETS. The market for Internet products and
services has only recently developed. Since this market is relatively new and
because current and future competitors are likely to introduce competing
Internet products and services, and because both DCI and we have only limited
market experience for our respective products and services, we cannot predict
the rate at which the market for our products and services or for DCI's products
and services will grow or at which new or increased competition will result in
market saturation. If the Internet markets or the markets for our products and
services or DCI's products and services fail to grow, grow more slowly than we
anticipate or become saturated with competitors, our business, including the
businesses of DCI if the DCI Merger is completed, operating results and
financial condition will be materially adversely affected.

         DEPENDENCE ON BROADBAND OPERATORS. Certain of our services are
dependent on the quality of the cable system infrastructure. Cable system
operators have announced and have begun to implement major infrastructure
upgrades in order to increase the capacity of their networks and to deploy two-
way capability. These upgrades have placed a significant strain on the
financial, managerial, operating and other resources of cable system operators,
most of which are already significantly leveraged. Further, cable system
operators must periodically renew their franchises with city, county, or state
governments and, as a condition of obtaining such renewal, may have to meet

                                       4
<PAGE>
 
certain conditions imposed by the issuing jurisdiction. These conditions may
have the effect of causing the cable system operator to delay such upgrades.
Although we provide Internet access services to cable system operators
irrespective of their two-way capabilities, to the extent we provide Internet
access services over cable systems to the home with a telephone line return path
for data from the home, our services may not provide the high speed, quality of
experience, and availability of certain applications, such as video
conferencing, necessary to attract and retain subscribers to our Internet
services. In addition, cable system operators are primarily concerned with
increasing television programming capacity to compete with other modes of
multichannel entertainment delivery systems such as DBS and may, therefore,
choose to roll-out set-top boxes that are incompatible with and do not support
high-speed Internet access services, rather than to upgrade their network
infrastructures as described above. The failure of cable system operators to
complete these upgrades in a timely and satisfactory manner, or at all, would
adversely affect the market for our products and services.

         We expect our contracts with cable system operators for our i2u
Community products and services to have terms of up to five years. There can be
no assurance that we will be able to renew any such contracts. Moreover, even if
cable system operators renew these contracts, there can be no assurance that
such renewals will be on terms satisfactory to the Company.

         Because users of our i2u Community products and services generally are
expected to subscribe through a broadband operator, the broadband operator (and
not us) will substantially control the customer relationship with the users.
Therefore, in addition to our business being subject to general economic and
market conditions and factors relating to ISPs and online services specifically,
the success and future growth of our business may also be subject to economic
and other factors affecting broadband operators.

         PRODUCT DEVELOPMENT; TECHNOLOGICAL CHANGE. Our future success will
depend upon our ability to develop new products and services that meet changing
customer requirements. The markets for our, and DCI's, products and services are
characterized by rapidly changing technology, evolving industry standards,
emerging competition and frequent new product and service introductions. We may
not be able to successfully identify new product and service opportunities or
develop and bring new products and services to market in a timely manner. Even
if we are able to successfully identify, develop and introduce new products and
services there is no assurance that a market for these products will
materialize. Furthermore, products and services or technologies developed by
others may render ours, and DCI's, products, services, and technologies
noncompetitive or obsolete.

         GENERAL RISKS OF BUSINESS. We have formulated our business plans and
strategies based on the rapidly increasing size of the Internet markets, our
anticipated participation in those markets, and the estimated sales cycle, price
and acceptance of our products and services. Although these assumptions are
based on our best estimates, there is no assurance that our assumptions will
prove to be correct. We have not commissioned or obtained any independent
marketing studies, either with respect to our current business, or the business,
products and technologies of DCI, nor are any such studies planned. Any future
success that we might enjoy will depend upon many factors including some beyond
our control or that we cannot predict at this time.

         SIGNIFICANT CONCENTRATION OF CUSTOMERS. Our customer base is highly
concentrated among a limited number of customers, seven as of November 30, 1998,
primarily due to the fact that the cable television and telecommunications
industries in the United States are dominated by a limited number of large
companies and to the relatively short time that we have been offering our
current products and services. Except for geographically contiguous systems, our
customers do not experience significant economies of scale by purchasing
additional systems from us. There is no assurance that we will be able to
attract or retain major customers. The loss of, or reduction in demand for
products or related services from, any of our major customers could have a
material adverse effect on our business, operating results, cashflows and
financial condition.

         INTENSE COMPETITION. The market for Internet products and services is
highly competitive, and we expect this competition to intensify in the future.
Many nationally known companies and regional and local companies across the
country are involved in Internet applications and the number of competitors is
growing. We also compete with broadband companies who are developing their own
Internet access and content and with the internal departments of prospective
customers who are retaining Internet-related activities in-house. Even if a
prospective customer chooses to outsource its Internet-related activities, that
customer may choose to outsource these activities to a company other than us.

                                       5
<PAGE>
 
         DCI's and our current and prospective competitors include many
companies whose financial, technical, marketing and other resources are
substantially greater than ours. Increased competition could result in
significant price competition, which in turn could result in significant
reductions in the average selling price of our products and services. In
addition, increased competition could cause us to increase our spending on
marketing, sales and product development. There is no assurance that we will be
able to offset the effects of any such price reductions or increases in spending
through an increase in the number of our customers, higher sales from enhanced
services, cost reductions or otherwise. Therefore, any of these events could
have a materially adverse effect on our financial condition and operating
results. There is no assurance that we will have the financial resources,
technical expertise or marketing, sales and support capabilities to compete
successfully.

         LIMITED AVAILABILITY OF PROPRIETARY PROTECTION. We do not believe that
our current products or services, or the products or services of DCI, are
patentable. We rely on a combination of copyright, trade secret and trademark
laws, and nondisclosure and other contractual provisions to protect our
proprietary rights. Policing unauthorized use of proprietary systems and
products is difficult and, while we are unable to determine the extent to which
piracy of our software exists, we expect software piracy to be a persistent
problem. In addition, the laws of some foreign countries do not protect software
to the same extent as do the laws of the United States. There is no assurance
that the steps we take to protect our proprietary rights will be adequate to
prevent the imitation or unauthorized use of our proprietary rights. Even if the
steps we take to protect our proprietary rights prove to be adequate, our
competitors may develop products or technologies that are both non-infringing
and substantially equivalent or superior to our products or technologies.

         LENGTH OF SALES CYCLE. The decision to enter the Internet services
provisioning business is often an enterprise-wide decision by prospective
customers and may require us to engage in lengthy sales cycles. Our pursuit of
sales leads typically involves an analysis of our prospective customer's needs,
preparation of a written proposal, one or more presentations and contract
negotiations. We often provide significant education to prospective customers
regarding the use and benefits of Internet technologies and products. While our
sales cycle varies from customer to customer, it typically has ranged from one
to six months for i2u projects. Our sales cycle may also be subject to a
prospective customer's budgetary constraints and internal acceptance reviews,
over which we have little or no control. A significant portion of our revenues
are expected to come from Internet access fees paid by subscribers of our
broadband operator customers, advertising revenues and in connection with 
e-commerce transactions conducted using our products. We expect that it may take
broadband operators several months or more to market and sell high-speed
Internet access to their subscribers, to establish a significant enough user
base to attract advertisers and for users to conduct significant e-commerce
transactions. For these reasons, we do not expect to realize significant
revenues, if at all, from these activities until a significant time after we
have licensed our i2u products and services.

         POTENTIAL FLUCTUATIONS IN QUARTERLY RESULTS. As a result of our limited
operating history and the recent increased focus on our i2u products and
services, we do not have historical financial data for a sufficient number of
periods on which to base planned operating expenses. Therefore, our expense
levels are based in part on our expectations as to future sales and to a large
extent are fixed. We typically operate with little backlog and the sales cycles
for our products and services may vary significantly. As a result, our quarterly
sales and operating results generally depend on the volume and timing of and the
ability to close customer contracts within the quarter, which are difficult to
forecast. We may be unable to adjust spending in a timely manner to compensate
for any unexpected sales shortfalls. If we were unable to so adjust, any
significant shortfall of demand for our products and services in relation to our
expectations would have an immediate adverse effect on our business, operating
results and financial condition. Further, we currently intend to increase our
capital expenditures and operating expenses in order to fund product development
and increase sales and marketing efforts. To the extent that such expenses
precede or are not subsequently followed by increased sales, our business,
operating results and financial condition will be materially adversely affected.

         DEPENDENCE ON KEY PERSONNEL; ABSENCE OF EMPLOYMENT AND NONCOMPETITION
AGREEMENTS. We are highly dependent on the technical and management skills of
our key employees, including in particular R. Steven Adams, our founder,
President and Chief Executive Officer. The loss of Mr. Adams' services could
have a material adverse effect on our business and operating results. We have
not entered into employment agreements with Mr. Adams, or any of our other
officers or employees. We do not maintain key person insurance for Mr. Adams or
any other member of management. We generally enter into written nondisclosure
and nonsolicitation agreements with our officers and employees which restrict
the use and disclosure of proprietary information and the solicitation of

                                       6
<PAGE>
 
customers for the purpose of selling competing products or services. Thus, if
any of these officers or key employees left OSS, they could compete with us, so
long as they did not solicit our customers. Any such competition could have a
material adverse effect on our business.

         Our future success also depends in part on our ability to identify,
hire and retain additional personnel, including key product development, sales,
marketing, financial and executive personnel. Competition for such personnel is
intense and there is no assurance that we can identify or hire additional
qualified personnel. In addition, the success of the DCI Merger is highly
dependent on the technical and management skills of Andre Durand, the founder,
President and Chief Executive Officer of DCI. The loss of Mr. Durand's services
could have a material adverse affect on the value of the DCI Merger. The DCI
Merger is contingent on Mr. Durand entering into a three-year non-compete
agreement with OSS.

         MANAGEMENT OF EXPECTED GROWTH. We expect to experience significant
growth in the number of our employees, the scope of our operating and financial
systems, and the geographic area of our operations, including the expansion of
our international operations. In addition, as we expand our i2u products and
services, we will need to hire additional employees who will be located at many
widely separated offices, including international offices. Our ability to
successfully manage any such growth will require us to continue to implement and
improve our operational, financial and management information systems. In
addition, this growth will result in new and increased responsibilities for
existing management personnel and will require us to hire and train new
management personnel. There can be no assurance that our management or other
resources will be sufficient to manage any future growth in our business or that
we will be able to implement in whole or in part our growth strategy and any
failure to do so could have a material adverse effect on our operating results
and financial condition.

         SECURITY RISKS. Our software and equipment may be vulnerable to
computer viruses or similar disruptive problems caused by our customers or other
Internet users. Computer viruses or problems caused by third parties could lead
to interruptions, delays or cessation in service to our customers. In addition,
while our i2u software integrates software designed to provide a secure
environment for e-commerce, these safeguards may prove to be inadequate. We have
information technology insurance which provides limited coverage for losses
caused by computer viruses, however, certain losses resulting from misuse of
software or equipment by third parties or losses from computer viruses which
exceed the liability limits under such insurance may not be protected. Although
we attempt to limit our liability to customers for these types of risks through
contractual provisions, there is no assurance that these limitations will be
enforceable.

         DEPENDENCE ON THE INTERNET. The success of our business depends in
large part upon a robust industry and infrastructure for providing Internet
access and carrying Internet traffic and upon the widespread acceptance and use
of electronic commerce over the Internet. Because global commerce and online
exchange of information on the Internet and other similar open wide area
networks are new and evolving, it is difficult to predict with any assurance the
extent to which the Internet will prove to be a significant commercial
marketplace. If the Internet does not become a significant commercial
marketplace, our business, operating results and financial condition could be
materially impaired.

         RISKS ASSOCIATED WITH INTERNATIONAL SALES. We have and are currently
pursuing marketing opportunities in international markets. International sales
are subject to a variety of risks, including difficulties in establishing and
managing international distribution channels, obtaining export licensing,
servicing and supporting overseas products and in translating the products'
graphical user interfaces into foreign languages. International operations are
subject to difficulties in collecting accounts receivable, staffing and managing
personnel and enforcing intellectual property rights. Other factors that can
also adversely affect international operations include fluctuations in the value
of foreign currencies and currency exchange rates, changes in import/export
duties and quotas, introduction of tariff or non-tariff barriers and regulatory,
economic or political changes in international markets.

         GOVERNMENT REGULATION. We are not currently subject to direct
regulation by any government agency, other than regulations applicable to
businesses generally, and there are currently few laws or regulations directly
applicable to access to or commerce on the Internet. However, due to the
increasing popularity and use of the Internet, a number of legislative and
regulatory proposals are under consideration by federal, state, local and
foreign governmental organizations, and it is possible that a number of laws or
regulations may be adopted with respect to the Internet relating to such issues
as user privacy, user screening to prevent inappropriate uses of the Internet
by, for example, minors or convicted criminals, taxation, infringement, pricing,
content regulation, quality of products 

                                       7
<PAGE>
 
and services and intellectual property ownership and infringement. The adoption
of any such laws or regulations may decrease the growth in the use of the
Internet, which could in turn decrease the demand for our products and services,
increase our cost of doing business, or otherwise have a material adverse effect
on our business, results of operations and financial condition. Moreover, the
applicability to the Internet of existing laws governing issues such as property
ownership, copyright, trademark, trade secret, obscenity, libel and personal
privacy is uncertain and developing. Our business, results of operations and
financial condition could be materially adversely effected by any new
legislation or regulation, or application or interpretation of existing laws to
the Internet.

         YEAR 2000. The Year 2000 issue involves the potential for system and
processing failures of date-related data resulting from computer-controlled
systems using two digits rather than four to define the applicable year. For
example, computer programs that contain time-sensitive software may recognize a
date using two digits of "00" as the year 1900 rather than the year 2000. This
could result in system failure or miscalculations causing disruptions of
operations, including, among other things, a temporary inability to process
transactions, send invoices or engage in similar ordinary business activities.

         We believe that our internal software and hardware systems will
function properly with respect to dates in the year 2000 and thereafter and we
have completed our internal IT and non-IT assessment. We expect to incur no
significant costs in the future for Year 2000 problems. Nonetheless, there is no
assurance in this regard until such systems are operational in the Year 2000. We
are in the process of contacting all of our significant suppliers to determine
the extent to which our systems are vulnerable to those third parties' failure
to make their own systems Year 2000 compliant. We expect to have completed this
review by the second quarter of fiscal 1999. In the event any of our suppliers
or vendors prove not to be Year 2000 compliant, we believe that we could find a
replacement vendor or supplier which is Year 2000 compliant without significant
delay or expense. However, if substantially all of our suppliers and vendors
prove not to be Year 2000 compliant and if we experience difficulties in finding
replacement vendors, then, as a result, our business could be materially
adversely affected. The failure to correct material Year 2000 problems by our
suppliers and vendors could result in an interruption in, or a failure of,
certain of our normal business activities or operations. Such failures could
materially and adversely affect our results of operations, liquidity and
financial condition. Due to the general uncertainty inherent in the Year 2000
problem, resulting from the uncertainty of the Year 2000 readiness of
third-party suppliers and vendors and of our customers, we are unable to
determine at this time whether the consequences of Year 2000 failures will have
a material impact on our results of operations, liquidity or financial
condition.

         LIMITATION OF DIRECTORS' LIABILITY. Our Articles of Incorporation
provide, as permitted by Colorado law, that our directors shall have no personal
liability for certain breaches of their fiduciary duties to us. In addition, our
Bylaws provide for mandatory indemnification of directors and officers to the
fullest extent permitted by Colorado law. These provisions may reduce the
likelihood of derivative litigation against directors and may discourage
shareholders from bringing a lawsuit against directors for a breach of their
duty.

RISKS RELATED TO THE OFFERING

         PENDING ACQUISITION OF DCI; POSSIBLE DILUTION TO OSS SHAREHOLDERS
CAUSED BY THE ACQUISITION. On March 19, 1998, we executed an Agreement and Plan
of Merger pursuant to which we agreed to acquire DCI. We have filed a Proxy
Statement/Prospectus with the Securities and Exchange Commission relating to
this acquisition, and we expect that the acquisition will be completed in the
first quarter of fiscal 1999. The acquisition is subject to, among other things,
approval by our shareholders and the shareholders of DCI. In the event that the
DCI acquisition is not completed as proposed, DCI has agreed to license its
CommunityWare product to us on at least as favorable terms as it licenses such
product to others. As of the date of this prospectus, we have loaned DCI
approximately $1,288,000 to maintain its operations pending completion of the
acquisition and have paid DCI, by reducing the balance of the note receivable,
approximately $490,000 for services rendered in connection with the integration
of CommunityWare with our i2u products and services. If the DCI acquisition is
not completed, DCI would not have the ability to repay our advances without
obtaining significant additional working capital through the sale of its
securities. There is no assurance that DCI would be able to raise working
capital in the amounts required.

         If the DCI acquisition is consummated, it will result in an increase in
our outstanding shares of common stock by 955,649 (approximately 23%). On a
pro forma basis, we estimate that the issuance of such shares would have
resulted in an increase to our net book value per share as of September 30, 1998
from $0.76 (actual) to $2.83 (pro forma) and $2.82 (pro forma adjusted to
reflect the subsequent conversions of 10% Preferred Stock and 5% Preferred Stock
and the subsequent issuance of Series A Preferred Stock). In addition to issuing
the shares of common stock, we will reserve approximately 240,000 shares of our
common stock for issuance upon exercise of outstanding options and warrants

                                       8
<PAGE>
 
of OSS that will be issued in connection with the acquisition, and we will
reserve approximately 40,000 shares of our common stock for issuance upon
conversion of convertible securities of DCI that will be assumed by OSS in
connection with the DCI Merger. There is no assurance that our results of
operations will improve enough, if at all, as a result of the DCI acquisition,
to offset possible future dilution which could occur to our shareholders as a
result of the DCI acquisition if our operations achieve profitability.

         POSSIBLE VOLATILITY OF STOCK PRICES; PENNY STOCK RULES. The over-the-
counter markets for securities such as our common stock historically have
experienced extreme price and volume fluctuations during certain periods. These
broad market fluctuations and other factors, such as new product developments
and trends in our industry and the investment markets generally, as well as
economic conditions and quarterly variations in our results of operations, may
adversely affect the market price of our shares. Although our shares are listed
on The Nasdaq SmallCap Market ("Nasdaq"), there can be no assurance that they
will remain eligible to be included on Nasdaq. If our common stock was no longer
eligible for quotation on Nasdaq, it could become subject to rules adopted by
the Securities and Exchange Commission regulating broker-dealer practices in
connection with transactions in "penny stocks." If the common stock became
subject to the penny stock rules, many brokers may be unwilling to engage in
transactions in the common stock because of the added regulation, thereby making
it more difficult for purchasers of our common stock to dispose of their shares.

         RIGHTS TO ACQUIRE SHARES; POTENTIAL SUBSTANTIAL DILUTION. As of 
November 30, 1998, we had issued the following warrants and options to acquire
shares of common stock:

         -        Options and warrants to purchase 1,651,614 shares of common
                  stock upon exercise of such options and warrants, exercisable
                  at prices ranging from $0.50 to $8.50 per share, with a
                  weighted average exercise price of approximately $5.65 per
                  share.

         -        Warrants issued in connection with our initial public offering
                  on May 23, 1996 (the "IPO Warrants") to purchase 634,150
                  shares upon exercise of the IPO Warrants at an exercise price
                  of $9.00 per share.

         -        Options issued to EBI Securities Corporation, the
                  representative of the underwriters involved in such initial
                  public offering (the "Representative's Option"), to purchase
                  106,700 shares upon exercise of the Representative's Option at
                  a purchase price of $8.10 per share.

         -        the Representative's Option to purchase 106,700 IPO Warrants
                  issuable upon exercise of the Representative's Option at a
                  purchase price of $.001 per IPO Warrant. These IPO Warrants
                  entitle the holder thereof to purchase up to 53,350 shares
                  upon exercise of such IPO Warrants at an exercise price of
                  $9.00 per share.

         -        Warrants issued in connection with the issuance of the 10%
                  Preferred Stock to purchase 53,500 shares of common stock upon
                  exercise of such warrants, exercisable at $15.00 per share.

         -        Warrants issued in connection with the issuance of the 5%
                  Preferred Stock to purchase 100,000 shares of common stock
                  upon exercise of such warrants, exercisable at $16.33 per
                  share.

         -        Warrants issued in connection with the issuance of the Series
                  A Preferred Stock to purchase 140,000 shares of common stock
                  upon exercise of such warrants, exercisable at $5.71 per
                  share.

In addition to these warrants and options, we have reserved an indeterminate
number of shares of common stock for issuance upon conversion of outstanding
shares of our 10% and Series A Preferred Stock, we will issue 955,649 shares of
our common stock upon the completion of the DCI Merger, we will reserve
approximately 240,000 shares for issuance upon exercise of options and warrants
to be issued in connection with the DCI acquisition, and we will reserve
approximately 40,000 shares of our common stock for issuance upon conversion of
convertible securities of DCI that will be assumed by OSS in connection with the
DCI Merger. The 10% Preferred Stock is convertible into shares of common stock
at the lesser of $10 or 80% of the market value (as defined) of the common stock
at the time of the conversion of such 10% Preferred Stock. The Series A
Preferred Stock is convertible into shares of common stock at the lesser of
$5.71 or 80% of the market value (as defined) of the common stock at the time of
the conversion of such Series A Preferred Stock. Based on the market value for
the common stock as of November 30, 1998, the 10% Preferred Stock is convertible
into approximately 367,228 shares of common stock and the Series A Preferred
Stock is convertible into approximately 339,137 shares of common stock. The
number of shares of common stock issuable upon conversion of the 10% Preferred
Stock and the Series A Preferred Stock could increase significantly

                                       9
<PAGE>
 
in the event that the market value for the common stock decreases in the future.
During the terms of the outstanding options, warrants and convertible
securities, the holders thereof will have the opportunity to profit from an
increase in the market price of the Common Stock with resulting dilution to the
holders of shares who purchased shares for a price higher than the respective
exercise or conversion price. The existence of such stock options, warrants and
convertible securities may adversely affect the terms on which we can obtain
additional financing, and you should expect the holders of such options or
warrants to exercise or convert those securities at a time when we, in all
likelihood, would be able to obtain additional capital by offering securities on
terms more favorable to us than those provided by the exercise or conversion of
such options or warrants.

         SHARES ELIGIBLE FOR FUTURE SALE. Sales of substantial amounts of common
stock in the public market, or even the potential for such sales, could have an
adverse effect on the market price for shares of our common stock, and could
impair the ability of purchasers of our common stock recoup their investment or
make a profit. Furthermore, such sales could affect our ability to raise capital
through the sale of equity securities. As of November 30, 1998 approximately
1,130,000 of our currently outstanding shares of common stock are
"restricted shares." Restricted shares and shares of the common stock owned by
our affiliates (officers, directors and holders of 10% of our outstanding common
stock) may be publicly sold only by complying with Rule 144 under the Securities
Act unless further registered under the Securities Act, or some other exemption
from further registration thereunder is available. While the shares of the
common stock to be issued to the shareholders of DCI in connection with the
acquisition of DCI will be subject to certain contractual limitations on the
transfer of such shares prior to September 30, 1999, such shares or a portion
thereof could be sold prior to September 30, 1999.

         ABILITY TO ISSUE COMMON STOCK AND PREFERRED STOCK; ANTI-TAKEOVER
DEVICES. Our Articles of Incorporation authorize our Board of Directors to issue
up to 20,000,000 shares of common stock and 5,000,000 shares of preferred stock
in one or more series, the terms of which may be determined at the time of
issuance by the Board of Directors, without further action by our shareholders.
Preferred stock authorized by the Board of Directors may include voting rights,
preferences as to dividends and liquidation, conversion and redemptive rights
and sinking fund provisions. As of November 30, 1998, our Board of Directors has
authorized the issuance of up to (i) 500,000 shares of 10% Preferred Stock (the
"10% Preferred Stock"), of which 245,000 shares were outstanding, (ii) 3,000
shares of 5% Preferred Stock, of which no shares were outstanding, and (iii)
1,400 shares of Series A Preferred Stock, of which 1,400 shares were
outstanding. Although our Board of Directors has no present plans to issue any
other shares of preferred stock, if the Board of Directors authorizes the
issuance of preferred stock in the future, such authorization could affect the
rights of the holders of common stock, thereby reducing the value of the common
stock, and could make it more difficult for a third party to acquire OSS, even
if a majority of the holders of common stock approved of such acquisition.

         AFFECT OF ISSUANCE OF 10%, 5% AND SERIES A PREFERRED STOCK ON NET LOSS.
Based on current accounting standards, we estimate that we will be required to
record a non-operating expense of approximately $4,100,000 for the fiscal year
ending December 31, 1998 as a result of the issuance of the 10%, 5% and Series A
Preferred Stock. While these charges will not affect our operating loss or
working capital during such period, they are expected to result in an increase
of approximately $4,100,000 in the Company's net loss available to our holders
of common stock for the fiscal year ending December 31, 1998.

         NO DIVIDENDS. We have never paid dividends on our common stock and do
not intend to pay any dividends on our common stock in the foreseeable future.
Any decision by us to pay dividends will depend upon our profitability at the
time, cash available therefor, and other factors. We anticipate that we will
devote profits, if any, to our future operations. Except as otherwise required
by law, we are required to pay a quarterly cumulative noncompounded dividend on
the 10% Preferred Stock of 10% per annum based on the stated value of $10.00 per
share of 10% Preferred Stock, and we are required to pay all accrued but
undeclared dividends on the Series A Preferred Stock on the earlier of (1) the
redemption or conversion of the Series A Preferred Stock, or (2) the liquidation
of the Company.

 
               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS
                                        
         Certain statements made in this prospectus and the documents

(the "Reform Act"). These statements are subject to the safe harbor provisions
of the Reform Act. Forward-looking statements may be identified by the use of
the terminology such as "may," "will," "expect," "anticipate," "intend,"
"believe," "estimate," "should," or "continue" or the negatives thereof or other
variations thereon or comparable terminology. To the extent that this prospectus
contains forward-looking statements regarding the financial condition, operating
results, business prospects or any other aspect of OSS or DCI, you should be
aware that OSS's and DCI's actual financial condition, operating results and
business performance may differ materially from that projected or estimated by
OSS or DCI in the forward- looking statements. OSS and DCI have attempted to
identify, in context, certain of the factors that they currently believe may
cause actual future experience and results to differ from their current
expectations. These differences may be caused by a variety of factors, including
but not limited to adverse economic conditions, intense competition, including
entry of new competitors, ability to obtain sufficient financing to support OSS'
and DCI's operations, progress in research and development activities,
variations in costs that are beyond OSS' and DCI's control, changes in capital
expenditure budgets for cable companies, adverse federal, state and local
government regulation, inadequate capital, unexpected costs, lower sales and net
income (or higher net losses) than forecasted, price increases for equipment,
inability to raise prices, failure to obtain new customers, the possible
fluctuation and volatility of OSS' and DCI's operating results and financial
condition, inability to carry out marketing and sales plans, loss of key
executives, and other specific risks that may be alluded to in this prospectus.


                                USE OF PROCEEDS
                                        
         We will not receive any proceeds from the sale of the shares offered by
this prospectus, however, certain shares offered by this prospectus are issuable
only upon the exercise of issued and outstanding transferable warrants of OSS.
If these warrants are exercised in full and the exercise price is paid in cash
rather than by a surrender of a portion of the warrants being exercised (a
cashless exercise), we will receive proceeds of $3,234,9000. We will use such
proceeds, if any, for general working capital purposes.

                              RECENT DEVELOPMENTS
                                        
DCI ACQUISITION

         On March 19, 1998 we executed an Agreement and Plan of Merger (the "DCI
Merger Agreement") pursuant to which we agreed to acquire Durand Communications,
Inc., a California corporation ("DCI"), via a merger of our wholly owned
subsidiary, Durand Acquisition Corporation, with DCI (the "DCI Merger"). As
consideration for the DCI Merger, we will issue 955,649 shares of our common
stock in exchange for 100% of the outstanding shares of common stock, no par
value, of DCI. In connection with the DCI Merger, we will also issue options and
warrants for approximately 240,000 shares of our common stock at exercise prices
ranging from $4.31 to $20.33 in replacement of similar securities of DCI. We
expect DCI to have liabilities of approximately $1,200,000 (including 
approximatley $381,000 of convertible securities which will be converted into 
similar convertible securities of OSS) at the time of the DCI Merger, which 
will become the liabilities of the consolidated entities upon consummation
of the DCI Merger. We will reserve approximately 40,000 shares of our common 
stock to be issued upon the conversion of these convertible securities. Under
the rules of The Nasdaq SmallCap Market ("Nasdaq") our issuance of our common
stock as consideration for the DCI Merger requires the approval of our
shareholders. Approval by our shareholders is a condition precedent to our
obligation to consummate the DCI Merger. If our issuance of shares of common
stock is not approved by our shareholders, it is unlikely that we will
consummate the DCI Merger. We anticipate that the meeting at which our
shareholders will consider the issuance of such common stock will occur in
the first quarter of 1999.

         We anticipate that the DCI Merger, for federal income tax purposes,
will be treated as a reorganization within the meaning of Section 368 of the
Internal Revenue Code (the "Code") and that each of OSS, DCI and Durand
Acquisition Corporation will be a party to the reorganization within the meaning
of Section 368(b) of the Code. Based on the facts, representations, warranties
and agreements set forth in the DCI Merger Agreement, we believe that the DCI
Merger will so qualify. However, we have not requested a ruling from the
Internal Revenue Service (the "IRS") with respect to these matters. Therefore,
the IRS may determine that the DCI Merger does not qualify to be treated as a
reorganization within the meaning of Section 368 of the Code.

         A significant element of OSS' strategy to achieve its growth objective
is to seek acquisitions that add immediate revenue, provide product or
technology enhancements in one or more of our targeted markets or provide an
existing customer base to increase advertising or e-commerce opportunities. Our
acquisition of DCI will provide us with DCI's technology, including both
completed technology and technology in development and product development
expertise.

                                       11
<PAGE>
 
         Our product development strategy is based upon our belief that the Web
is evolving from an information access and delivery tool to a system that
supports communication and community interactivity. We believe that DCI's
CommunityWare technology, which enables users to organize themselves on the
Internet in a matter of minutes, and to thereafter manage and expand their own
public and private online community to facilitate and promote communications,
information sharing and commerce among the users that comprise the various
constituent communities, is particularly well suited for providing the
communications component for OSS' i2u software. Since the execution of the DCI
Merger Agreement, representatives of DCI and OSS have worked together to
incorporate the CommunityWare technology into our i2u software. We recently
introduced a version of the i2u product which incorporates elements of the
CommunityWare technology. Following the DCI Merger, we intend to integrate DCI's
product development efforts with our own. In addition, we expect to fully
integrate DCI's products with our i2u products and to market them as part of our
product offerings and not on a stand-alone basis.

         We believe that the primary value of DCI to OSS is (i) DCI's
proprietary technology, particularly DCI's CommunityWare technology, (ii) DCI's
software development capabilities which our management believes is important to
our ability to continue to develop state-of-the-art proprietary software
products required to maintain long-term relationships with our customers, and
(iii) the ability the DCI acquisition will give us to greatly reduce the time it
will take us to introduce new proprietary software products. Our management
believes DCI's technology can be quickly integrated with our i2u products to
expand the breadth and functionality of its product offerings. Andre Durand,
Chief Executive Officer of DCI, has been elected Senior Vice President-Product
Development of OSS and will be responsible for our product development efforts.
A condition to the DCI Merger is that Mr. Durand enter into a three-year
noncompete agreement with OSS. We intend to continue to employ most of DCI's
product development personnel following the DCI Merger.

         We also believe that DCI's Electronic University Network ("EUN")
business, which offers accredited online courses for colleges, universities and
corporations, represents a valuable business opportunity. We expect to continue
to develop this business both as a separate product offering and as an adjunct
to our product offerings for broadband operators.

         We did not seek an opinion from an independent financial advisor as to
the value of the DCI transaction, as management and the Board of Directors
determined that management of OSS was best able to determine the value of the
acquisition since its value was primarily based on the capabilities and
prospects for DCI's technology, the compatibility of DCI's and OSS' technologies
and the ability to quickly integrate the two technologies in order to
significantly reduce OSS' time to develop and introduce new products and to
increase the value of OSS' product offerings. In connection with the
negotiations with DCI, we also considered the fact that DCI had sold shares of
its common stock at prices, based on the conversion ratio of DCI common stock
into OSS common stock in connection with the DCI Merger, from $8.11 to $18.94
per share since December 31, 1996. Based on these factors, the OSS Board of
Directors determined that the proposed purchase price for DCI was reasonable and
fair to OSS and its shareholders.

         The acquisition of DCI will increase the outstanding number of shares
of our common stock by 955,649 shares (approximately 23%) (excluding shares
issuable upon the exercise of options and warrants or the conversion of
convertible securities issued in connection with the DCI Merger), will increase
our liabilities, on a consolidated basis, by approximately $1,200,000 and is
expected to increase our operating net loss by approximately $130,000 per month
for at least the next six months. The acquisition of DCI will also increase our
working capital requirements. Although we have entered into a letter of intent
pursuant to which we would obtain approximately $4,500,000 of additional net
capital, there is no assurance that we will be successful in obtaining
additional working capital or, if successful, that the cost of such capital will
be acceptable.

         The DCI Merger Agreement contemplates that we will acquire 100% of the
outstanding common stock of DCI. Based on the average closing price of our
common stock for the two days before and the two days after March 19, 1998, the
day that the transaction was announced, the total purchase price is estimated to
be approximately $13,100,000, consisting of (i) 955,649 shares of our common
stock to be issued to the stockholders of DCI, (ii) approximately 240,000 shares
of our common stock to be reserved for issuance upon the exercise of options and
warrants of DCI to be exchanged for similar securities of OSS; and (iii)
approximately $400,000 of expenses to be incurred. In addition, DCI will have
approximately $1,200,000 of liabilities (including approximately $381,000 of
convertible securities which will be converted into similar convertible
securities of OSS) at the time of the DCI Merger, which will become the
liabilities of the consolidated entities upon consummation of the DCI Merger. We
will reserve approximately 40,000 shares of our common stock to be issued upon
the conversion of these convertible securities.

                                       12

         The DCI Merger will be accounted for under the purchase method of
accounting, with the purchase price allocated to the fair value of assets
acquired. A significant portion of such amount and liabilities assumed on a
consolidated basis has been identified as intangible assets, including
approximately $500,000 of research and development in process. The portion
of the purchase price and liabilities assumed on a consolidated basis which is
allocated to in-process research and development will be recognized as expense
in the period the DCI Merger is consummated (currently expected to be the first
quarter of fiscal 1999).

         DCI completed the acquisition of CompuLearning Systems, d/b/a
Electronic University Network ("EUN") during January 1998. Based on financial
information provided by DCI and EUN, the combined revenues for DCI and EUN for
the year ended December 31, 1997 totaled $740,739 and their combined loss for
the same period equaled ($2,867,973). For the nine months ended September 30,
1998, revenues for DCI were $545,353, including $290,251 of services provided to
OSS. In addition, DCI's accumulated deficit at September 30, 1998 was
$(8,061,004) and DCI's shareholders' deficit at September 30, 1998 was
$(1,219,356). We estimate that, on a pro forma basis, the acquisition of DCI
would have resulted in a decrease to the net book value of our shares of common
stock as of September 30, 1998 from $0.76 (actual) to $2.83 (pro forma) and 
$2.82 (pro forma adjusted to reflect the subsequent conversions of 10% Preferred
Stock and 5% Preferred Stock and the subsequent issuance of Series A Preferred
Stock).

         The final determination of the value of consideration issued by OSS and
the liabilities assumed will be made at the effective time of the DCI Merger.
Accordingly, the determination of the total purchase price, liabilities assumed
and the allocations may change significantly from the amounts stated in this
prospectus.


                              SELLING SHAREHOLDERS
                                        
         The following table sets forth, as of November 30, 1998, the name of
each of the Selling Shareholders, certain beneficial ownership information with
respect to each of the Selling Shareholders, and the number and percentage of
securities offered by this prospectus that may be sold from time to time by the
Selling Shareholders pursuant to this prospectus. Unless otherwise indicated,
the number of shares of common stock set forth in the following table that is
being offered by the Selling Shareholders who will receive their shares of
common stock upon the conversion of the 10% Preferred Stock or the conversion of
the Series A Preferred Stock represents an estimate of the number of shares of
common stock that such Selling Shareholder will offer. The actual number of
shares of our common stock that we may issue to such Selling Shareholders upon
conversion of the 10% Preferred Stock or the Series A Preferred Stock is
indeterminate, is subject to adjustment, and could be materially less or more
than such estimated number depending on factors that we cannot predict at this
time, including, among other factors, the future market price of our common
stock. The actual number of shares of common stock offered by this prospectus,
and included in the Registration Statement of which this prospectus is a part,
includes such additional number of shares of common stock that we may be
required to issue upon conversion of the 10% Preferred Stock or the Series A
Preferred Stock by reason of the floating rate conversion price mechanism or the
other adjustment mechanisms described in this prospectus, or by reason of any
stock split, stock dividend or similar transaction involving our common stock,
in order to prevent dilution, in accordance with Rule 416 under the Securities
Act of 1933, as amended. There is no assurance that the Selling Shareholders
will sell the shares offered by this prospectus.

                              PLAN OF DISTRIBUTION
                                        
         We have been advised that the shares offered by this Prospectus may be
sold from time to time by the Selling Shareholders or by pledgees, donees,
transferees or other successors in interest. Such sales may be made in the
Nasdaq SmallCap Market or such other over-the-counter market or otherwise at
prices and at terms then prevailing or at prices related to the then current
market price or in negotiated transactions. Such shares may be sold by one or
more of the following:

         -        A block trade in which the broker or dealer so engaged will
                  attempt to sell shares as agent but may position and resell a
                  portion of the block as principal to facilitate the
                  transaction.

         -        Purchases by a broker or dealer as principal and resale by
                  such broker or dealer for its account pursuant to this
                  prospectus. 

         -        Ordinary brokerage transactions and transactions in which the
                  broker solicits purchasers. 

                                       16
<PAGE>
 
         -        In privately negotiated transactions not involving a broker or
                  dealer.

         In effecting sales, brokers or dealers engaged to sell the shares may
arrange for other brokers or dealers to participate. Brokers or dealers engaged
to sell the shares will receive compensation in the form of commissions or
discounts in amounts to be negotiated immediately prior to each sale. Such
brokers or dealers and any other participating brokers or dealers may be deemed
to be "underwriters" within the meaning of the Securities Act of 1933, as
amended, in connection with such sales. OSS will receive no proceeds from any
resales of the shares offered by this prospectus, and we anticipate that the
brokers or dealers, if any, participating in the sales of such shares will
receive the usual and customary selling commissions.

         To comply with the securities laws of certain states, if applicable,
the shares will be sold therein only through brokers or dealers. In addition, in
certain states, the shares may not be sold unless they have been registered or
qualified for sale in such states or an exemption from registration or
qualification is available and is complied with.


                           DESCRIPTION OF SECURITIES
GENERAL

         Our Articles of Incorporation authorize our Board of Directors to issue
25,000,000 shares of capital stock, including 20,000,000 shares of common stock,
no par value, and 5,000,000 shares of preferred stock, with such par value and
such rights, preferences and privileges as are determined by the Board of
Directors.

COMMON STOCK

         As of November 30, 1998, 4,225,088 shares of our common stock were
outstanding. Holders of common stock are entitled to dividends when, as and if
declared by the Board of Directors out of funds available therefor, subject to
loan agreement limitations and priority as to dividends for preferred stock that
may be outstanding. Holders of common stock are entitled to cast one vote for
each share held at all stockholder meetings for all purposes, including the
election of directors. The holders of more than 50% of the voting power of the
common stock issued and outstanding and entitled to vote, present in person or
by proxy, (together with any preferred stock issued and outstanding and entitled
to vote, present in person or by proxy) constitute a quorum at all meetings of
our shareholders. The vote of the holders of a majority of common stock present
at such a meeting (together with any preferred stock present and entitled to
vote at such meeting) will decide any question brought before such meeting,
except when Colorado law, our Articles of Incorporation, or our Bylaws require a
greater vote and except when Colorado law requires a vote of any preferred stock
issued and outstanding, voting as a separate class, to approve a question
brought before such meeting. If we liquidate or dissolve, the holders of each
outstanding share of common stock will be entitled to share equally in our
assets legally available for distribution to such shareholder after payment of
all liabilities and after distributions to holders of preferred stock legally
entitled to such distributions. Holders of common stock do not have any
preemptive, subscription or redemption rights. Holders of common stock do not
have cumulative voting for the election of directors. All outstanding shares of
common stock are fully paid and nonassessable and the shares of common stock
offered by this prospectus will be, upon issuance, fully paid and nonassessable.
The holders of the common stock do not have any registration rights with respect
to the common stock.

10% PREFERRED STOCK

         As of November 30, 1998, 245,000 shares of our 10% Preferred Stock were
outstanding. The following is a summary of the rights, privileges and
preferences of the 10% Preferred Stock. This summary is qualified in its
entirety by reference to the terms of the 10% Preferred Stock incorporated by
reference as an exhibit to the registration statement of which this prospectus
is a part.

         VOTING. Each share of 10% Preferred Stock entitles the holder to one
vote per share. The holders of the common stock and the 10% Preferred Stock vote
as a single class on all matters on which our shareholders vote, except where
otherwise required by law. The holders of the 10% Preferred Stock do not have
cumulative voting for the election of directors.

                                       17

         DIVIDENDS. The cumulative noncompounded dividend on the 10% Preferred
Stock is 10% per annum based on the stated value of $10.00 per share, payable
quarterly as permitted by law, or upon the redemption or conversion of the 10%
Preferred Stock into common stock. We may not declare or pay any dividends on
the common stock unless we first declare and pay all unpaid dividends on the 10%
Preferred Stock.

         REDEMPTION AND CONVERSION. We may redeem the 10% Preferred Stock at any
time for $10.00 per share. Each share of the outstanding 10% Preferred Stock is
convertible, at the election of the holder thereof, into the number of shares of
our common stock equal to $10.00 divided by the lesser of (i) $10.00 or (ii) 80%
of the average per share closing bid price of the our common stock for the five
trading days immediately preceding the election by the holder thereof (as
calculated, the "Average Per Share Closing Bid Price"). If we elect to redeem
the 10% Preferred Stock, then we must give not more than 60 days and not less
than 30 days notice to the holders of the 10% Preferred Stock of our intent to
redeem the 10% Preferred Stock. This notice must provide the holders of the 10%
Preferred Stock the option to have their 10% Preferred Stock either (1) redeemed
by us or (2) converted into shares of our common stock pursuant to the formula
set forth in (i) and (ii) above except that for the purposes of calculating the
conversion rate the Average Per Share Closing Bid Price shall be defined as the
average per share closing bid price of our common stock for the five trading
days immediately preceding that date on which we first give such notice to the
holders of the 10% Preferred Stock. At any time while any shares of the 10%
Preferred Stock are outstanding, we may not incur any obligations (other than
trade payables and other short-term indebtedness issued in the ordinary course
of business) that are senior to the 10% Preferred Stock in any respect,
including liquidation. Upon any redemption or conversion of the 10% Preferred
Stock, we will have the option to pay the accrued but unpaid cumulative
dividends on the 10% Preferred Stock either (i) in cash, or (ii) by issuing
additional shares of common stock utilizing a price per share equal to the
lesser of (a) $10.00 or (b) if a redemption or a conversion occurring in
connection with the receipt of a notice of redemption, the average per share
closing bid price for the five trading days immediately preceding the date on
which we first give notice of such redemption to the holders of the 10%
Preferred Stock, or, if a conversion occurring without connection to the receipt
of a notice of redemption, the average per share closing bid price of our common
stock for the five trading days immediately preceding the election to convert by
the holder of the 10% Preferred Stock.

         PREEMPTIVE RIGHTS. The holders of the 10% Preferred Stock do not have
preemptive rights to subscribe for any additional shares of any class of our
capital stock or for any issue of bonds, notes or other securities convertible
into any class of our capital stock.

         LIQUIDATION PREFERENCE. If we liquidate, dissolve or wind-up our
business, whether voluntary or otherwise, after we pay our debts and other
liabilities, the holders of the 10% Preferred Stock will be entitled to receive
from our remaining net assets, before any distribution to the holders of our
common stock, the amount of $10.00 per share of 10% Preferred Stock in cash plus
payment of all accrued but unpaid cumulative dividends. Holders of the 10%
Preferred Stock will not be entitled to receive any other payments if we
liquidate, dissolve or wind-up our business.

SERIES A PREFERRED STOCK

         As of November 30, 1998, 1,400 shares of our Series A Preferred Stock
were outstanding. The following is a summary of the rights, privileges and
preferences of the Series A Preferred Stock. This summary is qualified in its
entirety by reference to the terms of the Series A Preferred Stock incorporated
by reference as an exhibit to the Registration Statement of which the prospectus
is a part.

         VOTING. Each share of Series A Preferred Stock entitles the holder to
cast the number of votes equal to the number of whole shares of common stock
into which the Series A Preferred Stock held by such holder are convertible
immediately after the close of business on the record date fixed for meeting at
which the vote is to be taken. The holders of the Series A Preferred Stock do
not have cumulative voting for the election of directors.

         DIVIDENDS. The cumulative noncompounded dividend on the Series A
Preferred Stock is 5% per annum based on the stated value of $1,000 per share,
payable as permitted by law, at our option, in cash or in common stock upon the
earlier of (1) the redemption or conversion of the Series A Preferred Stock or
(2) the liquidation of OSS. We may not declare and pay any dividends on the
common stock unless all we first declare and pay all unpaid dividends on the
Series A Preferred Stock. Dividends on the Series A Preferred Stock are equal in
preference to any dividends declared on the 10% Preferred Stock.

         REDEMPTION AND CONVERSION. We may redeem the Series A Preferred Stock,
in whole or in part, at any time on or prior to February 7, 1999 for a price per
share equal to $1,000 plus any accrued but unpaid dividends. The redemption
price per share will increase to $1,150 plus any accrued but unpaid dividends if
the registration statement to be filed with the Securities and Exchange
Commission to register the shares of common stock issuable upon the conversion
of the Series A Preferred Stock and the shares of common stock issuable upon the
exercise of certain warrants issued in connection with the issuance of the
Series A Preferred Stock has not been declared effective and remains effective
on the date that we give notice of redemption of the Series A Preferred Stock.
Each share of the outstanding Series A Preferred Stock is convertible, subject
to the limitation described below, at any time at the election of the holder
thereof, into the number of shares of common stock equal to $1,000 divided by
the lower of (1) $5.71 or (2) 80% of the average per share closing bid price of
the common stock for any five consecutive trading days during the twenty trading
days immediately preceding the date on which the holder thereof elects to
convert such Series A Preferred Stock (the "Conversion Price"). If we elect to
redeem the Series A Preferred Stock, we must give at least thirty days notice to
the holders of the Series A Preferred Stock of our intent to redeem the Series A
Preferred Stock. During this thirty day notice period, the holders, the holders
of the Series A Preferred Stock are entitled to convert their shares of Series A
Preferred Stock into common stock at the Conversion Price applicable on the day
such holder elects to convert such Series A Preferred Stock. After such thirty
day period, the holders of the Series A Preferred Stock may not thereafter
convert the Series A Preferred Stock into shares of common stock. Upon any
conversion of the Series A Preferred Stock we have the option to pay the accrued
but unpaid cumulative dividend on the Series A Preferred Stock either (1) in
cash or (2) by issuing additional shares of common stock calculated by adding
the amount of the accrued but unpaid dividend into the $1,000 stated value set
forth in the formula above.

         PREEMPTIVE RIGHTS. The holders of the Series A Preferred Stock have no
preemptive rights to subscribe for any additional shares of any class of our
capital stock or for any issue of bonds, notes or other securities convertible
into any class of our capital stock.

         LIQUIDATION PREFERENCE. If we liquidate, dissolve or wind-up our
business, whether voluntary or otherwise, after we pay our debts and other
liabilities, the holders of the Series A Preferred Stock will be entitled to
receive from our remaining net assets, before any distribution to the holders of
our common stock, the amount of $1,000 per share of Series A Preferred Stock in
cash plus payment of all accrued but unpaid dividends. The liquidation
preference on the Series A Preferred Stock is equal in preference to the
liquidation preference on the 10% Preferred Stock. Thereafter, holders of the
Series A Preferred Stock shall be entitled to share in any distributions made to
the holders of our common stock as if each share of Series A Preferred Stock was
converted (pursuant to the formula set forth above) into the number of shares of
common stock into which it is convertible immediately prior to the close of
business on the business day fixed for such distribution.

and elsewhere in the registration statement have been audited by Arthur Andersen
LLP, independent public accountants, as indicated in their reports with respect 
thereto, and are included herein in reliance upon the authority of said firm as

                                INDEMNIFICATION
                                        
         Our Articles of Incorporation provide that we shall indemnify, to the
full extent permitted by Colorado law, any of our directors, officers, employees
or agents who are made, or threatened to be made, a party to a proceeding by
reason of the fact that such person is or was one of our directors, officers,
employees or agents against judgments, penalties, fines, settlements and
reasonable expenses incurred by the person in connection with the proceeding if
certain standards are met. Insofar as indemnification for liabilities arising
under the Securities Act of 1933 (the "Act") may be permitted to our directors,
officers and controlling persons pursuant to these provisions, or otherwise, we
have been advised that, in the opinion of the SEC, such indemnification is
against public policy as expressed in the Act and is, therefore, unenforceable.

         Our Articles of Incorporation also limit the liability of our directors
to the fullest extent permitted by the Colorado law. Specifically, our Articles
of Incorporation provide that our directors will not be personally liable for
monetary damages for breach of fiduciary duty as directors, except for (i) any
breach of the duty of loyalty to OSS or its shareholders, (ii) acts or omissions
not in good faith or that involved intentional misconduct or a knowing violation
of law, (iii) dividends or other distributions of corporate assets that are in
contravention of certain statutory 

                                       20
<PAGE>
 
or contractual restrictions, (iv) violations of certain laws, or (v) any
transaction from which the director derives an improper personal benefit.
Liability under federal securities law is not limited by our Articles of
Incorporation.

ITEM 15.  INDEMNIFICATION OF OFFICERS AND DIRECTORS

         The Company's Articles of Incorporation provide that the Company shall
indemnify, to the full extent permitted by Colorado law, any director, officer,
employee or agent of the Company made or threatened to be made a party to a
proceeding, by reason of the fact that such person is or was a director,
officer, employee or agent of the Company against judgments, penalties, fines,
settlements and reasonable expenses incurred by the person in connection with
the proceeding if certain standards are met. Insofar as indemnification for
liabilities arising under the Securities Act of 1933 (the "Act") may be
permitted to directors, officers and controlling persons of the Company pursuant
to the foregoing provisions, or otherwise, the Company has been advised that in
the opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Act and is, therefore, unenforceable.

         The Company's Articles of Incorporation limit the liability of its
directors to the fullest extent permitted by Colorado law. Specifically, the
Articles of Incorporation provide that directors of the Company will not be
personally liable for monetary damages for breach of fiduciary duty as
directors, except for (i) any breach of the duty of loyalty to the Company or
its shareholders, (ii) acts or omissions not in good faith or that involved
intentional misconduct or a knowing violation of law, (iii) dividends or other
distributions of corporate assets that are in contravention of certain statutory
or contractual restrictions, (iv) violations of certain laws, or (v) any
transaction from which the director derives an improper personal benefit.
Liability under federal securities law is not limited by the Articles.

ITEM 17.  UNDERTAKINGS

         A. 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
         to:

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

                  (b)      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 together,
                           represent a fundamental change in the information in
                           the registration statement, and
 
                  (c)      to include any additional or changed material
                           information on the plan of distribution;

                  (2) to treat, for determining liability under the Securities
         Act of 1933, each such post-effective amendment as 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; and

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

         B. Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers, and controlling
persons of the registrant as discussed above, 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.

     This Corporation shall exist in perpetuity, from and after the date of

of Colorado unless dissolved according to law.

                                  ARTICLE III
                                  -----------

                                    PURPOSES
                                    --------

     The purpose for which this corporation is organized is to engage in any
lawful act or activity for which corporations may be organized under the laws of
the State of Colorado.

     In furtherance of the foregoing purposes, the Corporation shall have and
may exercise all of the rights, powers and privileges now or hereafter conferred
upon corporations organized under the laws of the State of Colorado.  In
addition, it may do `everything necessary, suitable or proper for the
accomplishment of any of its corporate purposes.

                                   ARTICLE IV

corporation shall have authority to issue is 10,000 shares, all of one class,
Common Stock, having no par value.

     2.  Restrictions.  The Corporation shall have the right to impose
restrictions on the transfer of shares of the Corporation.

     3.  Dividends.  The Board of Directors may from time to time distribute to
shareholders in partial liquidation, or out of stated capital or capital surplus

limitations contained within the statutes of the State of Colorado.

     4.  Distribution in Liquidation.  Upon any liquidation, dissolution or

payment of all its obligations, the remainder of the assets of the Corporation
shall be distributed, either in cash or in kind, pro rata to the holders of the
Common Stock.

                             ----------------------

     1.  Voting Rights; No Cumulative Voting.  Each outstanding share of Common
Stock is entitled to the vote and each fractional share of Common Stock is
entitled to a corresponding fractional vote on each matter submitted to a vote
of shareholders.  Cumulative voting shall not be allowed in the election of
directors of the Corporation and every shareholder entitled to vote at such
election shall have the right to vote the number of shares owned by him for as
many persons as there are directors to be elected, and for whose election he has
a right to vote.

whether now or hereafter authorized, shall have any preemptive or similar right
to acquire any additional unissued or treasury shares of stock or securities of
any class or rights, warrants or options to purchase stock or scrip or
securities in any kind, including shares or securities convertible into shares
or carrying stock purchase warrants or privileges.

     3.  Majority Vote.  A quorum for the purpose of stockholder meetings will
consist of a majority of the shares issued and outstanding and entitled to vote
at the meeting.

     When a quorum is present, and when the statute requires a vote of two-
thirds of the shares entitled to vote to take action, the affirmative vote of a
majority of the shares issued and outstanding and entitled to vote on the
subject matter shall be the act of the stockholders.

     1.  No contract or other transaction between this Corporation and one or
more of its directors or any other corporation, firm, association, or entity in
which one or more of its directors are directors or officers or are financially
interested shall be either void or voidable solely because of such relationship
or interest or solely because such directors are present at the meeting of the
Board of Directors or a committee thereof which authorizes, approves, or
ratifies such contract or transaction or solely because their votes are counted
for such purpose if:

     (a) The material facts as to such relationship or interest and as to the
contract or transaction are disclosed or are otherwise known to the Board of
Directors or committee and the board or committee authorizes, approves, or
ratifies such contract or transaction by the affirmative vote of a majority of
the disinterested directors, even though the directors are less than a quorum;
or

<PAGE>
 
     (b) The material facts of such relationship or interest and as to the
contract of transaction are disclosed or otherwise known to the shareholders
entitled to vote thereon and they authorize, approve, or ratify such contract or
transaction by vote or written consent; or

     (c) The contract or transaction is fair and reasonable to the Corporation.

     2.  Common or interested directors may be counted in determining the
presence of a quorum at a meeting of the Board of Directors or a committee
thereof which authorizes, approves or ratifies such contract or transaction.

                                  ARTICLE VIII
                                  ------------

                             CORPORATE OPPORTUNITY
                             ---------------------

     The officers, directors and other members of management of this Corporation
shall be subject to the doctrine of "corporate opportunities" only insofar as it
applies to business opportunities in which this Corporation has expressed an
interest as determined from time to time by this Corporation's Board of
Directors as evidenced by resolutions appearing in the Corporation's minutes.
Once such areas of interest are delineated, all such business opportunities
within such areas of interest which come to the attention of the officers,
directors, and other members of management of this Corporation shall be offered
first to the Corporation.  In the event the Corporation declines to pursue any
or all such business opportunities, the officers, directors and other members.
of management of this Corporation shall be free to engage in such areas of
interest on their own and this doctrine shall not limit the right of any
officer, director or other member of management of this Corporation (other than
an officer, director, or member of management) from any duties which he may have
to this Corporation.

                                   ARTICLE IX
                                   ----------

                          INDEMNIFICATION OF OFFICERS,
                          ----------------------------

                              DIRECTORS AND OTHERS
                              --------------------

     1.  To the full extent permitted by the Colorado Corporation Code, the
Corporation shall indemnify any person who was or is a party or is threatened to
be made a party to any threatened, pending or completed action, suit or
proceeding, whether civil, criminal, administrative or investigative and whether
formal or informal (other than an action by or in the right of the Corporation)
by reason of the fact that he is or was a Director, Officer, employee, fiduciary
or agent of the Corporation, or is or was serving at the request of the
Corporation as a Director, Officer, employee, fiduciary or agent of another
corporation, 

                                       4
<PAGE>
 
partnership, joint venture, trust, employee benefit plan or other enterprise,
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding if he conducted himself in good faith and in a manner
he reasonably believed to be in or not opposed to the best interests of the
Corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful. The termination of any
action, suit or proceeding by judgment, order, settlement, or conviction, or
upon a plea of nolo contendere or its equivalent, shall not, of itself create a
presumption that the person did not act in good faith and in a manner which he
reasonably believed to be in or not opposed to the best interests of the
Corporation and, with respect to any criminal action or proceeding, had
reasonable cause to believe that his conduct was unlawful.

     2.  The Corporation shall indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action or
suit by or in the right of the Corporation to procure a judgment in its favor by
reason of the fact that he is or was a Director, Officer, employee, fiduciary or
agent of the Corporation, or is or was serving at the request of the Corporation
as a Director, Officer, employee or agent of another corporation, partnership,
joint venture, trust, employee benefit plan or other enterprise against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection with the defense or settlement of such action or suit if he acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the Corporation and except that no indemnification shall be
made in respect of any claim, issue or matter as to which such person shall have
been adjudged to be liable for negligence or misconduct in the performance of
his duty to the Corporation unless and only to the extent that the court in
which such action or suit was brought shall determine upon application that,
despite the adjudication of liability but in view of all circumstances of the
case, such person is fairly and reasonably entitled to indemnity for such
expenses which such court shall deem proper.

     3.  To the extent that a Director, Officer, employee, fiduciary or agent of
the Corporation has been wholly successful on the merits or otherwise in defense
of any action, suit or proceeding referred to in paragraphs 1 and 2 of this
Article, or in defense of any claim, issue or matter therein, he shall be
indemnified against expenses (including attorneys' fees) actually and reasonably
incurred by him in connection therewith.

                                       5
<PAGE>
 
     4.  Any indemnification under paragraphs 1 and 2 of this Article (unless
ordered by a court) shall be made by the Corporation only as authorized in the
specific case upon a determination that indemnification of the Director,
Officer, employee, fiduciary or agent is proper in the circumstances because he
has met the applicable standard of conduct set forth in paragraphs 1 and 2.
Such determination shall be made (1) by the Board of Directors by a majority
vote of a quorum consisting of Directors who were not parties to such action,
suit or pending, or (2) if such a quorum is not attainable, or, even if
obtainable a quorum of disinterested Directors so directs, by independent legal
counsel in a written opinion, or (3) by the stockholders.

     5.  Expenses (including attorneys' fees) incurred in defending a civil or
criminal action, suit or pending may be paid by the Corporation in advance of
the final disposition of such action, suit or proceeding as authorized in the
manner provided in paragraph 4 of this Article upon receipt of an undertaking by
or on behalf of the Director, Officer, employee, fiduciary or agent to repay
such amount unless it shall ultimately be determined that he is entitled to be
indemnified by the Corporation as authorized in this section.

     6.  The Corporation shall have power to purchase and maintain insurance on
behalf of any person who is or was a Director, Officer, employee, fiduciary or
agent of the Corporation, or is or was serving at the request of the Corporation
as a director, officer, employee or agent of another corporation, partnership,
joint venture, trust, employee benefit plan or other enterprise against any
liability asserted against him and incurred by him in any such capacity or
arising out of his status as such, whether or not the Corporation would have the
power to indemnify him against such liability under the provisions of this
section.

     7.  In addition to the foregoing, the Corporation shall have the power to
indemnify current or former directors, officers, employees and agents to the
fullest extent provided by the laws of the State of Colorado.

                                   ARTICLE X
                                   ---------

                               DIRECTOR LIABILITY
                               ------------------

     To the fullest extent permitted by the Colorado Corporation Code, as the
same exists or may hereafter be amended, a director of this Corporation shall
not be liable to the Corporation or its shareholders for monetary damages for
breach of fiduciary duty as a director.

     The undersigned, R. Steven Adams, President  of Online System Services,

                                   Exhibit A
                                        
         5. Designation of 10% Preferred Stock. The Corporation shall establish
and reserve for issuance from its 5,000,000 authorized shares of Preferred Stock
a class of preferred stock consisting of 500,000 shares to be known as the 10%
Preferred Stock (the "10% Preferred Stock"). The 10% Preferred Stock shall have
a stated value of $10.00 per share. The preferences, limitations and relative
rights of the 10% Preferred Stock shall be as provided in this Section 5.

         A. Voting Rights.

                  (1) Each outstanding share of the 10% Preferred Stock is
         entitled to one vote on each matter submitted to a vote of
         shareholders. The holders of the 10% Preferred Stock shall be entitled
         to vote on all matters voted upon by the holders of the Corporation's
         Common Stock. Unless otherwise required by law, the holders of the
         Common Stock and the holders of the 10% Preferred Stock shall vote as a
         single class on all matters submitted to a vote of shareholders.

                  (2) The holders of the 10% Preferred Stock shall not be
         entitled to any rights of cumulative voting with respect to their
         shares.

         B. Preemptive Rights. No holder of the 10% Preferred Stock shall have
any preemptive or similar right to acquire any additional unissued or treasury
shares of stock or securities of any class or rights, warrants or options to
purchase stock or scrip or securities in any kind, including shares or
securities convertible into shares or carrying stock purchase warrants or
privileges.

         C. Dividends.

                  (1) Dividends shall accrue on the 10% Preferred Stock at the
         rate of ten percent (10%) per annum on the stated value of the 10%
         Preferred Stock and shall be paid quarterly on the first of each
         January, April, July and October, beginning July 1, 1998, to the record
         holder thereof on the 15th of the previous month, subject to the
         limitations contained within the statutes of the State of Colorado.
         Dividends not paid in any quarter shall accumulate until paid, with
         interest on the unpaid balance, if any, accruing simple interest at the
         rate stated above. Subject to the foregoing limitations, dividends may
         be paid out of any funds legally available for such purpose.

                  (2) Dividends on the 10% Preferred Stock shall be declared and
         paid before dividends of any kind may be declared and paid on the
         Common Stock or any inferior class or series of stock and before
         distribution or any liquidation or distribution of any kind may be made
         upon the issued and outstanding Common Stock or any inferior class of
         stock.

                  (3) Upon any redemption or conversion of the 10% Preferred
         Stock pursuant to paragraphs G and H below, the Corporation shall pay
         all accrued but unpaid dividends on the 10% Preferred Stock called for
         redemption or converted, as the case may be. The Corporation may pay
         such accrued but unpaid dividends either (i) in cash or (ii) by issuing
         shares of Common Stock at a price per share equal to the lesser of (a)
         $10.00 or (b) if a redemption or a conversion occurring with respect to
         shares of the 10% Preferred Stock for which the Corporation has given a
         Notice of Redemption (as that term is defined in subparagraph G(2),
         below), the Average Per Share Closing Bid Price (as defined below) for
         the five trading days immediately preceding the date on which the
         Notice of Redemption was first given to the holders of the 10%
         Preferred Stock called for redemption, or, if a conversion occurring
         with respect to shares of the 10% Preferred Stock for which the
         Corporation has not given a Notice of Redemption, the Average Per Share
         Closing Bid Price for the five trading days immediately preceding the
         date on

                                       10
<PAGE>
 
          which the Conversion Notice (as that term is defined in subparagraph
          H(3), below) was first given to the Corporation.

                  (4) Upon payment by the Corporation of dividends on the basis
         described in subparagraphs C(1)-C(3), the holders of the 10% Preferred
         Stock shall have no further right to dividends and shall not
         participate in any manner in dividends declared and paid or other
         distributions on the Common Stock or any inferior class or series of
         stock.

         D. Liquidation Preference. In the event of the liquidation, dissolution
or winding up of the affairs of the Corporation, whether voluntary or
involuntary, the holders of the 10% Preferred Stock shall be entitled to
receive, after payment by the Corporation of its debts and liabilities, the
stated value of all shares of the 10% Preferred Stock in cash plus any all
accrued but unpaid dividends out of the assets of the Corporation before any
payment shall be made or any assets distributed to the holders of the Common
Stock or any other inferior class or series of stock. If sufficient assets are
not available to pay all holders of the 10% Preferred Stock in full, the
available assets shall be distributed to the holders of the 10% Preferred Stock
on a pro rata basis. Except as provided in this paragraph D, the holders of the
10% Preferred Stock shall not be entitled to receive any other payments from the
Corporation in the event of the liquidation, dissolution or winding up of the
affairs of the Corporation.

         E. Other Securities, Obligations.

                  (1) Subject to any limitations contained in these Articles of
         Incorporation, the Board of Directors of the Corporation reserves the
         right to establish additional classes and/or series of capital stock of
         the Corporation and to designate the preferences, limitations and
         relative rights of any such classes and/or series; provided, however,
         that no such class and/or series may have preferences, limitations and
         relative rights which are superior to or senior to the preferences,
         limitations and relative rights granted to the holders of the 10%
         Preferred Stock.

                  (2) At any time during which any shares of the 10% Preferred
         Stock are outstanding, the Corporation shall not incur any obligation
         or liability other than trade payables and other short-term
         indebtedness incurred in the ordinary course of business that is
         superior to or senior to the 10% Preferred Stock in any respects,
         including liquidation preferences.

         F. Capital Reorganization. If the Corporation shall at any time
hereafter subdivide or combine its outstanding shares of Common Stock, declare a
dividend payable in Common Stock, or in case of any capital reorganization or
reclassification of the shares of Common Stock of the Corporation, the number of
shares and stated value of the 10% Preferred Stock shall be adjusted
appropriately to allow the holders of the 10% Preferred Stock, as nearly as
reasonably possible, to maintain (i) the aggregate stated value of their 10%
Preferred Stock and (ii) their pro rata interest in the Corporation and in the
Common Stock upon conversion of the 10% Preferred Stock, that they had prior to
any such subdivision, combination, stock dividend, reorganization or
reclassification.

         G. Redemption.

                  (1) The 10% Preferred Stock may be redeemed by the
         Corporation, in whole or in part, at any time for $10.00 per share (the
         "Redemption Price"). It is the Corporation's intent to use its best
         efforts to raise sufficient capital to both fund its operations and to
         permit it to redeem the 10% Preferred Stock as soon as is reasonably
         possible. In addition, if the Corporation completes a public offering
         of its securities that raises net proceeds of at least $5,000,000 (the
         "Public Offering") within nine months from the date on which the
         initial closing of the offering of the 10% Preferred Stock occurs (the
         "Closing Date"), then the Corporation shall redeem all of the
         outstanding 10% Preferred Stock.

                                       11
<PAGE>
 
                  (2) The Corporation shall give not more than sixty (60) nor
         less than thirty (30) days notice (the "Notice of Redemption") of the
         date fixed for any redemption (as fixed, the "Redemption Date") of the
         10% Preferred Stock by mailing the Notice of Redemption to the record
         holders of the 10% Preferred Stock to such holder's address as it
         appears on the records of the Corporation; provided, however, that the
         Corporation shall not be required to give notice of any redemption of
         the 10% Preferred Stock that occurs within nine months from the Closing
         Date. In the case of a partial redemption of the 10% Preferred Stock,
         the shares to be redeemed shall be selected in any manner the
         Corporation may determine. The Notice of Redemption shall be deemed
         given when it is deposited in the United States mail with sufficient
         postage affixed or when it is delivered to the record holder at such
         holder's address as it appears on the records of the Corporation.

                  (3) On the Redemption Date, all rights of the holders of the
         10% Preferred Stock called for redemption shall cease and terminate
         with respect to such shares except (i) the right to receive the
         Redemption Price upon surrender of the certificates representing the
         shares of the 10% Preferred Stock called for redemption and (ii) the
         right to receive payment of all dividends with respect to the shares of
         10% Preferred Stock called for redemption which are accrued but unpaid
         on the Redemption Date.

         H. Conversion.

                  (1) If the 10% Preferred Stock is not redeemed within nine
         months from the Closing Date, each share of the outstanding 10%
         Preferred Stock shall become convertible, at the election of the holder
         thereof (the "Conversion Right"), into the number of shares of Common
         Stock of the Corporation equal to $10.00 divided by the lesser of (i)
         $10.00 or (ii) 80% of the Average Per Share Closing Bid Price of the
         Corporation's Common Stock as calculated pursuant to the next sentence
         The "Average Per Share Closing Bid Price" shall be (a) if the
         conversion occurs with respect to shares of the 10% Preferred Stock for
         which the Corporation has given a Notice of Redemption, the average per
         share closing bid price for the Corporation's Common Stock for the five
         trading days immediately preceding the date on which the Notice of
         Redemption was first given to the holders of the 10% Preferred Stock
         called for redemption or (b) if the conversion occurs with respect to
         shares of the 10% Preferred Stock for which the Corporation has not
         given a Notice of Redemption, the average closing bid price for the
         five trading days immediately preceding the date on which the holder
         gives the Conversion Notice (as that term is defined in subparagraph
         H(3), below) to the Corporation. The Closing Bid Price for the Common
         Stock at any date shall be (i) the Closing Bid Price of the Common
         Stock as reported in The Wall Street Journal (or, if not so reported,
         as otherwise reported by The Nasdaq Stock Market or, (ii) in the event
         that the Common Stock is listed on a stock exchange or on the Nasdaq
         National Market (or other national market), the Closing Bid Price shall
         be the closing price on the exchange or the Nasdaq National Market (or
         other national market), as the case may be, as reported in The Wall
         Street Journal (or, if not so reported, as otherwise reported by the
         stock exchange, Nasdaq or other national market). In the event that
         there is no reported Closing Bid Price or sale price, as the case may
         be, for a given day, the Closing Bid Price or sale price, as the case
         may be, for that day shall be deemed to be the Closing Bid Price or
         sale price, as the case may be, for the first day preceding such day
         for which there was a reported Closing Bid Price or sale price, as the
         case may be.

                  (2) The Conversion Right shall expire and terminate five (5)
         days prior to the Redemption Date. In the case of a partial redemption
         of the 10% Preferred Stock, the Conversion Right shall so expire and
         terminate only with respect to the shares of the 10% Preferred Stock
         called for redemption.

                  (3) In order to exercise the Conversion Right, the holder of
         the 10% Preferred Stock to be converted shall give written notice (the
         "Conversion Notice") to the 

                                       12
<PAGE>
 
         Corporation at its principal office or, at the option of the
         Corporation, at the offices of a conversion agent which the Corporation
         may designate from time to time by giving written notice of such
         designation to the holders of the 10% Preferred Stock, that the holder
         elects to convert such shares. The Conversion Notice shall be
         accompanied by the certificate or certificates representing the shares
         of the 10% Preferred Stock to be converted, duly endorsed to the
         Corporation. The Conversion Notice shall be deemed given when it is
         deposited in the United States mail with sufficient postage affixed or
         when it is delivered to the Corporation at its principal office (or to
         the offices of such conversion agent, if one be designated).


                  (4) As soon as practicable after the receipt of the Conversion
         Notice and the certificates representing the shares of the 10%
         Preferred Stock to be converted, the Corporation shall issue and shall
         deliver to the record holder of the shares so surrendered for
         conversion by mail to the address of such record holder as it appears
         on the records of the Corporation, a certificate or certificates for
         the number of shares of Common Stock issuable upon conversion of the
         shares of the 10% Preferred Stock and a residual certificate for shares
         of the 10% Preferred Stock, if any, not converted. Such conversion
         shall be deemed to have been effected on the date on which the
         Corporation (or the conversion agent, if one be designated), shall have
         received the Conversion Notice and the certificate or certificates
         representing shares of the 10% Preferred Stock to be converted, and the
         record holder shall be deemed to have become on such date the holder of
         record of the shares of Common Stock to be received upon conversion;
         provided, however, that any such surrender on any date when the stock
         transfer books of the Corporation shall be closed in accordance with
         the bylaws of the Corporation shall not be deemed to constitute the
         record holder as the holder of shares of Common Stock to be received
         upon conversion for any purpose until the close of business on the day
         succeeding the day on which such stock transfer books shall become
         open.

                  (5) The Corporation shall not be required to issue fractional
         shares of Common Stock upon conversion of shares of the 10% Preferred
         Stock. If any fractional interest in a share of Common Stock would be
         deliverable upon conversion of any shares of the 10% Preferred Stock,
         the Corporation shall make an adjustment therefor in cash at the
         current market value thereof, computed on the basis determined by the
         Corporation in its sole discretion.

     The undersigned, Thomas S. Plunkett, Chief Financial Officer of Online
System Services, Inc., a Colorado corporation (the "Corporation"), DOES HEREBY
CERTIFY that pursuant to actions taken by the Board of Directors on May 7, 1998
in accordance with Sections 7-106-101, 7-106-102 and 7-110-102 of the Colorado
Business Corporation Act, the following amendment was duly adopted by the Board
of Directors without shareholder approval as permitted by Section 7-106-102(4)
of the Colorado Business Corporation Act:


     ARTICLE IV of the Articles of Incorporation of the Corporation, as amended,
is further amended  by adding a new Section 6, the text of which is set forth on
Exhibit A attached hereto.


     IN WITNESS WHEREOF, the undersigned has executed these Articles of
Amendment this 22nd day of May, 1998.


                                    /s/ Thomas S. Plunkett

                                    Chief Financial Officer

                                       14
<PAGE>
 
                                                                       EXHIBIT A

         6. Designation of Preferred Stock. The Corporation shall establish and
reserve for issuance from its 5,000,000 authorized shares of Preferred Stock a
class of convertible preferred stock consisting of 3,000 shares to be designated
as the 5% Preferred Stock (the "5% Preferred Stock"). The 5% Preferred Stock
shall have a stated value of the Liquidation Preference (as hereinafter
defined). Except as otherwise expressly stated in this Section 6, all shares of
the 5% Preferred Stock shall be identical to the shares of 10% Preferred Stock,
and the holders of 5% Preferred Stock shall be entitled to the same preferences,
limitations and relative rights as the holders of 10% Preferred Stock.

         A. Dividends.

                  (1) Holders of the 5% Preferred Stock shall be entitled to
         receive, out of funds legally available therefor, dividends at a rate
         equal to 5% (the "Dividend Rate") of the Liquidation Preference per
         share per annum (subject to appropriate adjustments in the event of any
         stock dividend, stock split, combination or other similar
         recapitalization affecting such shares), and no more, payable in
         accordance with the provisions of this Section 6. Notwithstanding the
         foregoing sentence of this Subsection A(1), in the event the
         Registration Statement (as hereinafter defined) is not declared
         effective by the Securities and Exchange Commission (the "Commission")
         within 90 days following the Initial Closing Date (as defined in that
         certain Securities Purchase Agreement (the "Securities Purchase
         Agreement"), dated as of May 22, 1998, among the Corporation, the
         purchasers named therein and West End Capital LLC), then the Dividend
         Rate shall increase to 18% until the Registration Statement is declared
         effective; provided, however, that if the Commission conducts a review
         of the Registration Statement, the Dividend Rate shall not increase
         unless it is not declared effective by the Commission within 120 days
         following the Initial Closing Date, at which time the Dividend Rate
         shall increase to 18% until the Registration Statement is declared
         effective.

                  (2) At the election of the Corporation, each dividend on 5%
         Preferred Stock shall be paid either in shares of Common Stock or in
         cash on the Delivery Date (as defined in Subsection H(2)(a) of this
         Section 6) with respect to any shares of 5% Preferred Stock which are
         the subject of a Notice of Conversion (as defined in Subsection H(2)(a)
         of this Section 6). Dividends paid in shares of Common Stock shall be
         paid (based on an assumed value of $1,000 per share) in full shares
         only, with a cash payment equal to the value of any fractional shares.
         Each dividend paid in cash shall be mailed to the holders of record of
         the 5% Preferred Stock as their names and addresses appear on the share
         register of the Corporation or at the office of the transfer agent on
         the corresponding dividend payment date. Holders of 5% Preferred Stock
         will receive written notification from the Corporation or the transfer
         agent if a dividend is paid in kind, which notification will specify
         the number of shares of Common Stock paid as a dividend and the
         recipient's aggregate holdings of Common Stock as of that dividend
         payment date and after giving effect to the dividend. All holders of
         shares of Common Stock issued as dividends shall be entitled to all of
         the rights and benefits relating to shares of Common Stock as set forth
         in the Corporation's Articles of Incorporation, as amended, and
         By-laws.

                  (3) Holders of the 5% Preferred Stock shall be entitled to
         payment of any dividends in preference and priority to any payment of
         any cash dividend on Common Stock or any other class or series of
         capital stock of the Corporation other than any other class or series
         of stock ranking senior ("Senior Preferred Stock") to the 5% Preferred
         Stock in respect of dividends, when and as declared by the Board of
         Directors of the Corporation. The rights of the holders of 5% Preferred
         Stock and 10% Preferred Stock to receive any dividends shall be equal
         in preference and priority. Dividends on the 5% Preferred Stock shall
         accrue with respect to each share of the 5% Preferred Stock from the
         date on which such share is issued and outstanding and thereafter shall
         be deemed to accrue from day to day whether or not earned or declared
         and whether or not there exists 

                                       15
<PAGE>
 
         profits, surplus or other funds legally available for the payment of
         dividends, and shall be cumulative so that if such dividends on the 5%
         Preferred Stock shall not have been paid, or declared and set apart for
         payment, the deficiency shall be fully paid or declared and set apart
         for payment before any dividend shall be paid or declared or set apart
         for any Common Stock or other class or series of capital stock ranking
         junior to the 5% Preferred Stock (such stock being collectively
         referred to herein as the "Junior Stock") and before any purchase or
         acquisition of any Junior Stock is made by the Corporation, except the
         repurchase of Junior Stock from employees of the Corporation upon
         termination of employment. At the earlier of: (1) the redemption or
         conversion of the 5% Preferred Stock or (2) the liquidation of the
         Corporation, any accrued but undeclared dividends shall be paid to the
         holders of record of outstanding shares of the 5% Preferred Stock in
         accordance with the provisions of this Section 6. No accumulation of
         dividends on the 5% Preferred Stock shall bear interest.

         B. Liquidation, Dissolution or Winding Up.

                  (1) In the event of any voluntary or involuntary liquidation,
         dissolution or winding up of the Corporation, the holders of shares of
         the 5% Preferred Stock then outstanding shall be entitled to be paid
         out of the assets of the Corporation available for distribution to its
         stockholders, after and subject to the payment in full of all amounts
         required to be distributed to the holders of any Senior Preferred Stock
         ranking on liquidation prior and in preference to the Preferred Stock,
         but before any payment shall be made to the holders of Junior Stock by
         reason of their ownership thereof, an amount equal to $1,000 per share
         of 5% Preferred Stock (the "Liquidation Preference") plus any accrued
         but unpaid dividends (whether or not declared). The rights of the
         holders of 5% Preferred Stock and 10% Preferred Stock to receive any
         such distributions shall be equal in preference and priority. If upon
         any such liquidation, dissolution or winding up of the Corporation the
         remaining assets of the Corporation available for distribution to its
         shareholders shall be insufficient to pay the holders of shares of the
         5% Preferred Stock the full amount to which they shall be entitled, the
         holders of shares of the 5% Preferred Stock shall share ratably in any
         distribution of the remaining assets and funds of the Corporation in
         proportion to the respective amounts which would otherwise be payable
         in respect of the shares held by them upon such distribution if all
         amounts payable on or with respect to such shares were paid in full.

                  (2) After the payment of all preferential amounts required to
         be paid to the holders of the 5% Preferred Stock and the 10% Preferred
         Stock upon the dissolution, liquidation, or winding up of the
         Corporation, all of the remaining assets and funds of the Corporation
         available for distribution to its shareholders shall be distributed
         ratably among the holders of the 5% Preferred Stock and the Junior
         Stock, with each share of 5% Preferred Stock being deemed, for such
         purpose, to be equal to the number of shares of Common Stock, including
         fractions of a share, into which such share of 5% Preferred Stock is
         convertible immediately prior to the close of business on the business
         day fixed for such distribution.

         C. Voting.

                  (1) Each holder of outstanding shares of 5% Preferred Stock
         shall be entitled, at each meeting of shareholders of the Corporation
         (and with respect to written consents of shareholders in lieu of
         meetings) with respect to any and all matters presented to the
         shareholders of the Corporation for their action or consideration, to
         the number of votes equal to the number of whole shares of Common Stock
         into which the shares of 5% Preferred Stock held by such holder are
         convertible (as adjusted from time to time pursuant to Subsection H
         hereof) immediately after the close of business on the record date
         fixed for such meeting or the effective date of such written consent.
         Except as provided by law, by the provisions of Section J below, or by
         the provisions 

                                       16
<PAGE>
 
         establishing any other series of preferred stock, holders of 5%
         Preferred Stock shall vote together with the holders Common Stock as a
         single class.

                  (2) The holders of the 5% Preferred Stock shall not be
         entitled to any rights of cumulative voting with respect to their
         shares.

         D. Preemptive Rights. No holder of Preferred Stock shall have any
preemptive or similar right to acquire any additional unissued or treasury
shares of stock or securities of any class or rights, warrants or options to
purchase stock or scrip or securities in any kind, including shares or
securities convertible into shares or carrying stock purchase warrants or
privileges.

         E. Other Securities. Subject to any limitations contained in these
Articles of Incorporation, the Board of Directors of the Corporation reserves
the right to establish additional classes and/or series of capital stock of the
Corporation and to designate the preferences, limitations and relative rights of
any such classes and/or series; provided, however, that no such class and/or
series may have preferences, limitations and relative rights which are superior
to or senior to the preferences, limitations and relative rights granted to the
holders of the 5% Preferred Stock.

         F. Capital Reorganization. If the Corporation shall at any time
hereafter subdivide or combine its outstanding shares of Common Stock, declare a
dividend payable in Common Stock, or in case of any capital reorganization or
reclassification of the shares of Common Stock of the Corporation, the number of
shares of the 5% Preferred Stock and the stated value of the 5% Preferred Stock
shall be adjusted appropriately to allow the holders of the 5% Preferred Stock,
as nearly as reasonably possible, to maintain (i) the aggregate stated value of
the 5% Preferred Stock and (ii) their pro rata interest in the Corporation and
in the Common Stock upon conversion of the 5% Preferred Stock, that each holder
had prior to any such subdivision, combination, stock dividend, reorganization
or reclassification.

         G. Optional Redemption

                  (1) At any time within the 120 days following the Initial
         Closing Date, the Corporation may, at its option, redeem all or any
         portion of the shares of 5% Preferred Stock then outstanding upon not
         less than ten (10) days' notice at a redemption price per share equal
         to (A) the quotient of (i) the Liquidation Preference per share of 5%
         Preferred Stock plus all accrued but unpaid dividends on such shares of
         5% Preferred Stock and (ii) the Conversion Price as if the 5% Preferred
         Stock has been converted on the 5% Preferred Stock Redemption Date (as
         hereinafter defined) multiplied by (B) the average Closing Bid Price
         (as hereinafter defined) of shares of Common Stock for the five (5)
         trading days immediately preceding the 5% Preferred Stock Redemption
         Date. Notwithstanding the foregoing, a redemption shall not occur
         pursuant to this Subsection G(1) with respect to any 5% Preferred Stock
         for which a holder has previously submitted a Notice of Conversion
         pursuant to Subsection H of this Section 6. For purposes of this
         Section 6, the term "Closing Bid Price" means, for any security as of
         any date, the closing bid price on the principal securities exchange or
         trading market where the Common Stock is listed or traded as reported
         by Bloomberg, L.P. ("Bloomberg") or, if applicable, the closing bid
         price of the Common Stock in the over-the- counter market on the
         electronic bulletin board for such security as reported by Bloomberg,
         or, if no closing bid price is reported for the Common Stock by
         Bloomberg, then the average of the bid prices of any market makers for
         such security as reported in the "pink sheets" by the National
         Quotation Bureau, Inc. If the Closing Bid Price of the Common Stock
         cannot be calculated on such date on any of the foregoing bases, the
         Closing Bid Price of the Common Stock on such date shall be the fair
         market value as mutually determined by the Corporation and holders of a
         majority of the outstanding shares of 5% Preferred Stock being
         converted for which the calculation of the Closing Bid Price is
         required in order to determine the Conversion Price of such shares.
         "Trading day" shall mean any day on which the Corporation's Common
         Stock is traded for any period on the principal 

                                       17
<PAGE>
 
         securities exchange or other securities market on which the Common
         Stock is then being traded.

                  (2) Upon receipt of a notice given pursuant to Subsection
         G(1), each holder of 5% Preferred Stock shall accept its ratable
         portion (based on its holdings of 5% Preferred Stock as compared to the
         aggregate number of shares of 5% Preferred Stock then outstanding) of
         such offer by tendering such holder's shares to the Corporation for
         redemption, at an address to be set forth in such notice, at any time
         prior to 5:00 p.m. New York time on the 11th day following the mailing
         of such notice (the "5% Preferred Stock Redemption Date"). Upon receipt
         of a notice given pursuant to Subsection G(1) of this Section 6, the 5%
         Preferred Stock which is the subject of such notice may not thereafter
         be converted in accordance with Subsection H(1)(a) of this Section 6,
         unless a Notice of Conversion relating to such 5% Preferred Stock had
         previously been submitted. Within three (3) business days after the 5%
         Preferred Stock Redemption Date, the Corporation shall remit the
         applicable redemption price, calculated pursuant to Subsection G(1) of
         this Section 6, by wire transfer to each holder of the 5% Preferred
         Stock to the most recent address of each holder as set forth on the
         records of the Corporation or its transfer agent.

                  (3) Any shares of 5% Preferred Stock redeemed pursuant to this
         Subsection G or otherwise acquired by the Corporation in any manner
         whatsoever shall be canceled and shall not under any circumstances be
         reissued. The Corporation may from time to time take such appropriate
         corporate action as may be necessary to reduce accordingly the number
         of authorized shares of the Corporation's capital stock.

         H. Conversion.

                  (1) Subject to Subsection G(2) of this Section 6, the holders
         of the 5% Preferred Stock shall have conversion rights as follows (the
         "5% Preferred Stock Conversion Rights"):

                           (a) Each share of 5% Preferred Stock shall be
                  convertible, at the option of the holder thereof, at any time
                  and from time to time, into such number of fully paid and
                  nonassessable shares of Common Stock as is determined by
                  dividing $1,000, plus the amount of any accrued and unpaid
                  dividends the Corporation elects to pay in Common Stock, by
                  the Conversion Price in effect at the time of conversion. The
                  Conversion Price at which shares of Common Stock shall be
                  deliverable upon conversion of 5% Preferred Stock without the
                  payment of additional consideration by the holder thereof (the
                  "Conversion Price") shall be the lower of (i) $16.33 or (ii)
                  86% of the average Closing Bid Price of the shares of Common
                  Stock for the five (5) trading days immediately preceding the
                  5% Preferred Stock Conversion Date (as hereinafter defined).

                           (b) At any time that the number of shares of Common
                  Stock issued (A) upon conversion of the 5% Preferred Stock and
                  (B) in lieu of dividend payments on the 5% Preferred Stock,
                  shall equal 574,281 (a "Common Stock Redemption Event"), the
                  Corporation shall (x) redeem, at a price determined in
                  accordance with Subsection G(1) of this Section 6, all of the
                  outstanding 5% Preferred Stock in accordance with the
                  provisions of Subsection G(2) or (y) call a special meeting of
                  its shareholders for the purpose of approving the transactions
                  contemplated by the Securities Purchase Agreement, including
                  the issuance of the 5% Preferred Stock on the terms set forth
                  therein, together with any other approvals that shall be
                  required so as to cause the transactions contemplated by the
                  Securities Purchase Agreement to remain in compliance with the
                  Rules and Regulations of The Nasdaq Stock Market (including
                  Rule 4320 of Nasdaq's Non-Qualitative Designation Criteria in

                                       18

                  connection with conversions of 5% Preferred Stock; such
                  approvals are referred to herein as the "Required Approvals").
                  The Corporation shall determine within five (5) business days
                  following the receipt of a Notice of Conversion which of such
                  actions it shall take, and shall promptly furnish notice to
                  each of the holders of 5% Preferred Stock as to such
                  determination, including, if applicable, a notice of
                  redemption. In no event shall the Corporation issue shares of
                  Common Stock upon conversion of, or in lieu of interest
                  payments on, the 5% Preferred Stock, after the occurrence of a
                  Common Stock Redemption Event until the Required Approvals, if
                  any, are obtained.

                           (c) If the Corporation elects to call a special
                  meeting of its shareholders pursuant to Subsection H(1)(b) of
                  this Section 6 to obtain the Required Approvals, the
                  Corporation shall use its best efforts to obtain such Required
                  Approvals within one hundred twenty (120) days of the Initial
                  Closing Date (such one hundred twenty (120) day period is
                  referred to herein as an "Approval Period"). If the
                  Corporation does not obtain the Required Approvals within the
                  Approval Period and the Corporation receives a Notice of
                  Conversion after the termination of the Approval Period, the
                  Corporation must redeem, in accordance with this Subsection H
                  of this Section 6, any shares of 5% Preferred Stock
                  outstanding after the Corporation has issued in excess of
                  574,281 shares of Common Stock in connection with conversions
                  of the 5% Preferred Stock.

                           (d) If the Corporation elects, pursuant to this
                  Subsection H, to redeem the 5% Preferred Stock on the
                  occurrence of a Common Stock Redemption Event, it shall redeem
                  such 5% Preferred Stock at the price determined in accordance
                  with Subsection G(1) of this Section 6. If the Corporation
                  shall have elected, pursuant to this Subsection H(1), to
                  obtain the Required Approvals but shall not have done so by
                  the later of the occurrence of the Common Stock Redemption
                  Event or the expiration of the Approval Period, it shall
                  furnish a redemption notice to the Purchasers within three (3)
                  business days after the expiration of the Approval Period.

                  (2) The 5% Preferred Stock Conversion Rights shall be
         exercised as follows:

                           (a) The Corporation will permit each holder of 5%
                  Preferred Stock to exercise its right to convert the 5%
                  Preferred Stock by faxing an executed and completed notice of
                  conversion (the "Notice of Conversion") to the Corporation,
                  and delivering within three (3) business days thereafter, the
                  original Notice of Conversion (and the certificates
                  representing the related shares of 5% Preferred Stock) to the
                  Corporation by hand delivery or by express courier, duly
                  endorsed. Each date on which a Notice of Conversion is faxed
                  to and received in accordance with the provisions hereof shall
                  be deemed a "5% Preferred Stock Conversion Date." The
                  Corporation will transmit the certificates representing the
                  Common Stock issuable upon conversion of the 5% Preferred
                  Stock (together with certificates representing the related
                  shares of 5% Preferred Stock not so converted and, if
                  applicable, a check representing any fraction of a share not
                  converted) to such holder via express courier as soon as
                  practicable, but in all events no later than the later to
                  occur of (the "Delivery Date") (i) three (3) business days
                  after the 5% Preferred Stock Conversion Date, or (ii) three
                  (3) business days after receipt by the Corporation of the
                  original Notice of Conversion (and the certificates
                  representing the related shares of 5% Preferred Stock). For
                  purposes of this Section 6, such conversion of the 5%
                  Preferred Stock shall be deemed to have been made immediately
                  prior to the close of business on the 5% Preferred Stock
                  Conversion Date.

                           (b) In lieu of delivering physical certificates
                  representing the Common Stock issuable upon the conversion of
                  the 5% Preferred Stock, provided that the Corporation's
                  transfer agent is participating in the Depository Trust
                  Corporation ("DTC") Fast Automated Securities Transfer
                  program, on the written request of a holder of 5% Preferred
                  Stock who shall have previously instructed such holder's prime
                  broker to confirm such request to the Corporation's transfer
                  agent, the Corporation shall use commercially reasonable
                  efforts to cause its transfer agent to electronically transmit
                  such Common Stock to such holder by crediting the account of
                  the holder's prime broker with DTC through its Deposit
                  Withdrawal Agent Commission system no later than the
                  applicable Delivery Date.

                           (c) The Corporation will at all times have authorized
                  and reserved for the purpose of issuance a sufficient number
                  of shares of Common Stock to provide for the conversion of the
                  5% Preferred Stock. The Corporation will use its best efforts
                  at all times to maintain a number of shares of Common Stock so
                  reserved for issuance that is no less than one and one-half
                  (1.5) times the number that is then actually issuable upon the
                  conversion of the 5% Preferred Stock, the exercise of the
                  Warrants issued pursuant to the Securities Purchase Agreement
                  and the maximum number of shares of Additional Common Stock
                  (as defined in the Securities Purchase Agreement) which may be
                  issued in accordance with the Securities Purchase Agreement.
                  Before taking any action which would cause an adjustment
                  reducing the Conversion Price below the established par value
                  of the shares of Common Stock issuable upon conversion of the
                  5% Preferred Stock, the Corporation will take any corporate
                  action which may, in the opinion of its counsel, be necessary
                  in order that the Corporation may validly and legally issue
                  fully paid and nonassessable shares of Common Stock at such
                  adjusted Conversion Price.

                           (d) All shares of 5% Preferred Stock, which shall
                  have been surrendered for conversion as herein provided shall
                  no longer be deemed to be outstanding, and all rights with
                  respect to such shares, including the rights, if any, to
                  receive dividends, notices and to vote, shall immediately
                  cease and terminate on the 5% Preferred Stock Conversion Date,
                  except only the right of the holders thereof to receive shares
                  of Common Stock in exchange therefor. Any shares of 5%
                  Preferred Stock so converted shall be retired and canceled and
                  shall not be reissued, and the Corporation may from time to
                  time take such appropriate action as may be necessary to
                  reduce the number of shares of authorized 5% Preferred Stock
                  accordingly.

                  (3) In the event of a liquidation of the Corporation, the 5%
         Preferred Stock Conversion Rights shall terminate at the close of
         business on the first full day preceding the date fixed for the payment
         of any amounts distributable on liquidation to the holders of the 5%
         Preferred Stock.

                  (4) If the conversion is in connection with an underwritten
         offer of securities registered pursuant to the Securities Act of 1933,
         as amended, the conversion may, at the option of any holder tendering
         5% Preferred Stock for conversion, be conditioned upon the closing with
         the underwriter of the sale of securities pursuant to such offering, in
         which event the person(s) entitled to receive the Common Stock issuable
         upon such conversion of the 5% Preferred Stock shall not be deemed to
         have converted such 5% Preferred Stock until immediately prior to the
         closing of the sale of securities.

                  (5) At no time shall any holder of the 5% Preferred Stock
         convert such amount of 5% Preferred Stock as shall result in such
         Purchaser's ownership, after such conversion, exceeding 9.9% of the
         Corporation's outstanding Common Stock.

                                       20
<PAGE>
 
                  (6) No fractional shares of Common Stock shall be issued upon
         conversion of the Preferred Stock. In lieu of fractional shares, the
         Corporation shall pay cash equal to such fraction multiplied by the
         then effective and applicable Conversion Price.

                  (7) The Corporation will not, by amendment of its Articles of
         Incorporation or through any reorganization, transfer of assets,
         consolidation, merger, dissolution, issue or sale of securities or any
         other voluntary action, avoid or seek to avoid the observance or
         performance of any of the terms to be observed or performed under this
         Subsection H by the Corporation, but will at all times in good faith
         assist in the carrying out of all the provisions of this Subsection H
         and in the taking of all such action as may be necessary or appropriate
         in order to protect the 5% Preferred Stock Conversion Rights of the
         holders of the 5% Preferred Stock against impairment.

                  (8) In the event (a) that the Corporation declares a dividend
         (or any other distribution) on its Common Stock payable in Common Stock
         or other securities of the Corporation, (b) that the Corporation
         subdivides or combines its outstanding shares of Common Stock, (c) of
         any reclassification of the Common Stock of the Corporation (other than
         a subdivision or combination of its outstanding shares of Common Stock
         or a stock dividend or stock distribution thereon), (d) of any
         consolidation or merger of the Corporation into or with another
         corporation, (e) of the sale of all or substantially all of the assets
         of the Corporation, or (f) of the involuntary or voluntary dissolution,
         liquidation or winding up of the Corporation, then the Corporation
         shall cause to be filed at its principal office or at the office of the
         transfer agent of the Preferred Stock, and shall cause to be mailed to
         each holder of the Preferred Stock at their last address as shown on
         the records of the Corporation or such transfer agent, at least ten
         (10) days prior to the record date specified in (i) below or twenty
         (20) days before the date specified in (ii) below, a notice stating

                           (i) the record date of such dividend, distribution,
                  subdivision or combination, or, if a record is not to be
                  taken, the date as of which the holders of Common Stock of
                  record to be entitled to such dividend, distribution,
                  subdivision or combination are to be determined, or

                           (ii) the date on which such reclassification,
                  consolidation, merger, sale, dissolution, liquidation or
                  winding up is expected to become effective, and the date as of
                  which it is expected that holders of Common Stock of record
                  shall be entitled to exchange their shares of Common Stock for
                  securities or other property deliverable upon such
                  reclassification, consolidation, merger, sale, dissolution or
                  winding up.

         I. Sinking Fund. There shall be no sinking fund for the payment of
dividends, or liquidation preferences on the 5% Preferred Stock or the
redemption of any shares thereof.

         J. Amendment. This Section 6 constitutes an agreement between the
Corporation and the holders of the 5% Preferred Stock. The Corporation shall not
amend this Section 6 or alter or repeal the preferences, rights, powers or other
terms of the 5% Preferred Stock so as to affect adversely the 5% Preferred
Stock, without the written consent or affirmative vote of the holders of at
least sixty-six and two-thirds percent (662/3%) of the then outstanding shares
of 5% Preferred Stock, given in writing or by vote at a meeting, consenting or
voting (as the case may be) separately as a class.

                                   EXHIBIT A

     7.   Designation of Preferred Stock.  The Corporation shall establish and
reserve for issuance from its 5,000,000 authorized shares of Preferred Stock a
class of convertible preferred stock consisting of 1,400 shares to be designated
as the Series A Preferred Stock (the "Series A Preferred Stock").  The Series A
Preferred Stock shall have a stated value of the Liquidation Preference (as
hereinafter defined).  Except as otherwise expressly stated in this Section 7,
all shares of the Series A Preferred Stock shall be identical to the shares of
5% Preferred Stock and 10% Preferred Stock, and the holders of Series A
Preferred Stock shall be entitled to the same preferences, limitations and
relative rights as the holders of 5% Preferred Stock and 10% Preferred Stock.

         A. Dividends.

                  (1) Holders of the Series A Preferred Stock shall be entitled
         to receive, out of funds legally available therefor, dividends at a
         rate equal to 5% (the "Dividend Rate") of the Liquidation Preference
         per share per annum (subject to appropriate adjustments in the event of
         any stock dividend, stock split, combination or other similar
         recapitalization affecting such shares), and no more, payable in
         accordance with the provisions of this Section 7.

                  (2) At the election of the Corporation, each dividend on
         Series A Preferred Stock shall be paid either in shares of Common Stock
         or in cash on the Delivery Date (as defined in Subsection H(2)(a) of
         this Section 7) with respect to any shares of Series A Preferred Stock
         which are the subject of a Notice of Conversion (as defined in
         Subsection H(2) of this Section 7). Dividends paid in shares of Common
         Stock shall be paid (based on an assumed value of $1,000 per share) in
         full shares only, with a cash payment equal to the value of any
         fractional shares. Each dividend paid in cash shall be mailed to the
         holders of record of the Series A Preferred Stock as their names and
         addresses appear on the share register of the Corporation or at the
         office of the transfer agent on the corresponding dividend payment
         date. Holders of Series A Preferred Stock will receive written
         notification from the Corporation or the transfer agent if a dividend
         is paid in kind, which notification will specify the number of shares
         of Common Stock paid as a dividend and the recipient's aggregate
         holdings of Common Stock as of that dividend payment date and after
         giving effect to the dividend. All holders of shares of Common Stock
         issued as dividends shall be entitled to all of the rights and benefits
         relating to shares of Common Stock as set forth in the Corporation's
         Articles of Incorporation, as amended, and By-laws.

                  (3) Holders of the Series A Preferred Stock shall be entitled
         to payment of any dividends in preference and priority to any payment
         of any cash dividend on Common Stock or any other class or series of
         capital stock of the Corporation other than any other class or series
         of stock ranking senior ("Senior Preferred Stock") to the Series A
         Preferred Stock in respect of dividends, when and as declared by the
         Board of Directors of the Corporation. The rights of the holders of
         Series A Preferred Stock, 5% Preferred Stock and 10% Preferred Stock to
         receive any dividends shall be equal in preference and priority.
         Dividends on the Series A Preferred Stock shall accrue with respect to
         each share of the Series A Preferred Stock from the date on which such
         share is issued and outstanding and thereafter shall be deemed to
         accrue from day to day whether or not earned or declared and whether or
         not there exists profits, surplus or other funds legally available for
         the payment of dividends, and shall be cumulative so that if such
         dividends on the Series A Preferred Stock shall not have been paid, or
         declared and set apart for payment, the deficiency shall be fully paid
         or declared and set apart for payment before any dividend shall be paid
         or declared or set apart for any Common Stock or other class or series
         of capital stock ranking junior to the Series A Preferred Stock (such
         stock being collectively referred to herein as the "Junior Stock") and
         before any purchase or acquisition of any Junior Stock is made by the
         Corporation, except the repurchase of Junior Stock from employees of
         the Corporation upon termination of employment. At 

                                       24
<PAGE>
 
         the earlier of: (1) the redemption or conversion of the Series A
         Preferred Stock or (2) the liquidation of the Corporation, any accrued
         but undeclared dividends shall be paid to the holders of record of
         outstanding shares of the Series A Preferred Stock in accordance with
         the provisions of this Section 7. No accumulation of dividends on the
         Series A Preferred Stock shall bear interest.

         B. Liquidation, Dissolution or Winding Up.

                  (1) In the event of any voluntary or involuntary liquidation,
         dissolution or winding up of the Corporation, the holders of shares of
         the Series A Preferred Stock then outstanding shall be entitled to be
         paid out of the assets of the Corporation available for distribution to
         its stockholders, after and subject to the payment in full of all
         amounts required to be distributed to the holders of any Senior
         Preferred Stock ranking on liquidation prior and in preference to the
         Preferred Stock, but before any payment shall be made to the holders of
         Junior Stock by reason of their ownership thereof, an amount equal to
         $1,000 per share of Series A Preferred Stock (the "Liquidation
         Preference") plus any accrued but unpaid dividends (whether or not
         declared). The rights of the holders of Series A Preferred Stock, 5%
         Preferred Stock and 10% Preferred Stock to receive any such
         distributions shall be equal in preference and priority. If upon any
         such liquidation, dissolution or winding up of the Corporation the
         remaining assets of the Corporation available for distribution to its
         shareholders shall be insufficient to pay the holders of shares of the
         Series A Preferred Stock the full amount to which they shall be
         entitled, the holders of shares of the Series A Preferred Stock shall
         share ratably in any distribution of the remaining assets and funds of
         the Corporation in proportion to the respective amounts which would
         otherwise be payable in respect of the shares held by them upon such
         distribution if all amounts payable on or with respect to such shares
         were paid in full.

                  (2) After the payment of all preferential amounts required to
         be paid to the holders of the Series A Preferred Stock, 5% Preferred
         Stock and the 10% Preferred Stock upon the dissolution, liquidation, or
         winding up of the Corporation, all of the remaining assets and funds of
         the Corporation available for distribution to its shareholders shall be
         distributed ratably among the holders of the Series A Preferred Stock,
         5% Preferred Stock and the Junior Stock, with each share of Series A
         Preferred Stock being deemed, for such purpose, to be equal to the
         number of shares of Common Stock, including fractions of a share, into
         which such share of Series A Preferred Stock and 5% Preferred Stock are
         convertible immediately prior to the close of business on the business
         day fixed for such distribution.

         C. Voting.

                  (1) Each holder of outstanding shares of Series A Preferred
         Stock shall be entitled, at each meeting of shareholders of the
         Corporation (and with respect to written consents of shareholders in
         lieu of meetings) with respect to any and all matters presented to the
         shareholders of the Corporation for their action or consideration, to
         the number of votes equal to the number of whole shares of Common Stock
         into which the shares of Series A Preferred Stock held by such holder
         are convertible (as adjusted from time to time pursuant to Subsection H
         hereof) immediately after the close of business on the record date
         fixed for such meeting or the effective date of such written consent.
         Except as provided by law, by the provisions of Section J below, or by
         the provisions establishing any other series of preferred stock,
         holders of Series A Preferred Stock shall vote together with the
         holders Common Stock as a single class.

                  (2) The holders of the Series A Preferred Stock shall not be
         entitled to any rights of cumulative voting with respect to their
         shares.

         D. Preemptive Rights. No holder of Preferred Stock shall have any
preemptive or similar right to acquire any additional unissued or treasury
shares of stock or securities of any 

                                       25
<PAGE>
 
class or rights, warrants or options to purchase stock or scrip or securities in
any kind,  including  shares or securities  convertible  into shares or carrying
stock purchase warrants or privileges.

         E. Other Securities. Subject to any limitations contained in these
Articles of Incorporation, the Board of Directors of the Corporation reserves
the right to establish additional classes and/or series of capital stock of the
Corporation and to designate the preferences, limitations and relative rights of
any such classes and/or series; provided, however, that no such class and/or
series may have preferences, limitations and relative rights which are superior
to or senior to the preferences, limitations and relative rights granted to the
holders of the Series A Preferred Stock.

         F. Capital Reorganization. If the Corporation shall at any time
hereafter subdivide or combine its outstanding shares of Common Stock, declare a
dividend payable in Common Stock, or in case of any capital reorganization or
reclassification of the shares of Common Stock of the Corporation, the number of
shares of the Series A Preferred Stock and the stated value of the Series A
Preferred Stock shall be adjusted appropriately to allow the holders of the
Series A Preferred Stock, as nearly as reasonably possible, to maintain (i) the
aggregate stated value of the Series A Preferred Stock and (ii) their pro rata
interest in the Corporation and in the Common Stock upon conversion of the
Series A Preferred Stock, that each holder had prior to any such subdivision,
combination, stock dividend, reorganization or reclassification.

         G. Optional Redemption

                  (1) At any time within the 90 days following November 9, 1998,
         the Corporation may, at its option, redeem all or any portion of the
         shares of Series A Preferred Stock then outstanding upon not less than
         thirty (30) days' written notice at a redemption price per share equal
         to the Liquidation Preference of the Series A Preferred Stock plus any
         accrued but unpaid dividends (whether or not declared); provided, that
         if at the time of the notice of any such redemption, the Registration
         Statement to be filed by the Corporation pursuant to Section 2(a) of
         that certain Registration Rights Agreement dated November 9, 1998,
         between the Corporation and Archer Investors LLC has not been declared
         effective by the Securities and Exchange Commission and remains
         effective until the Series A Preferred Stock Redemption Date, the
         redemption price per share shall be equal to 115% of the Liquidation
         Preference of the Series A Preferred Stock plus any accrued but unpaid
         dividends (whether or not declared). Notwithstanding the foregoing, a
         redemption shall not occur pursuant to this Subsection G(1) with
         respect to any Series A Preferred Stock for which a holder has
         previously submitted a Notice of Conversion pursuant to Subsection H of
         this Section 7. For purposes of these Articles of Amendment, the term
         "Closing Bid Price" means, for any security as of any date, the closing
         bid price on the principal securities exchange or trading market where
         the Common Stock is listed or traded as reported by Bloomberg, L.P.
         ("Bloomberg") or, if applicable, the closing bid price of the Common
         Stock in the over-the-counter market on the electronic bulletin board
         for such security as reported by Bloomberg, or, if no closing bid price
         is reported for the Common Stock by Bloomberg, then the average of the
         bid prices of any market makers for such security as reported in the
         "pink sheets" by the National Quotation Bureau, Inc. If the Closing Bid
         Price of the Common Stock can not be calculated on such date on any of
         the foregoing bases, the Closing Bid Price of the Common Stock on such
         date shall be the fair market value as mutually determined by the
         Corporation and the holders of a majority of the outstanding shares of
         Series A Preferred Stock being converted for which the calculation of
         the Closing Bid Price is required in order to determine the Conversion
         Price of such shares. "Trading day" shall mean any day on which the
         Corporation's Common Stock is traded for any period on the principal
         securities exchange or other securities market on which the Common
         Stock is then being traded. 

                  (2) Upon receipt of a notice given pursuant to Subsection
         G(1), each holder of Series A Preferred Stock shall have thirty days to
         decide whether to accept its ratable portion (based on its holdings of
         Series A Preferred Stock as compared to the 

                                       26
<PAGE>
 
         aggregate number of shares of Series A Preferred Stock then
         outstanding) of such offer by tendering such holder's shares to the
         Corporation for redemption, at an address to be set forth in such
         notice, at any time prior to 5:00 p.m. New York time on the 30th day
         following the mailing of such notice (the "Series A Preferred Stock
         Redemption Date") or to convert all or a portion of the Series A
         Preferred Stock. Notwithstanding the foregoing, nothing herein shall
         limit the rights of the holders of the Series A Preferred Stock to
         convert the Series A Preferred Stock in whole or in part, prior to the
         Series A Preferred Stock Redemption Date. Within three (3) business
         days after the Series A Preferred Stock Redemption Date, the
         Corporation shall remit the applicable redemption price, calculated
         pursuant to Subsection G(1) of this Section 7, by wire transfer to each
         holder of the Series A Preferred Stock to the most recent address of
         each holder as set forth on the records of the Corporation or its
         transfer agent.

                  (3) Any shares of Series A Preferred Stock redeemed pursuant
         to this Subsection G or otherwise acquired by the Corporation in any
         manner whatsoever shall be canceled and shall not under any
         circumstances be reissued. The Corporation may from time to time take
         such appropriate corporate action as may be necessary to reduce
         accordingly the number of authorized shares of the Corporation's
         capital stock.

         H. Conversion.

                  (1) Subject to Subsection G(2) of this Section 7, the holders
         of the Series A Preferred Stock shall have conversion rights as follows
         (the "Series A Preferred Stock Conversion Rights"):

                           (a) Each share of Series A Preferred Stock shall be
                  convertible, at the option of the holder thereof, at any time
                  and from time to time, into such number of fully paid and
                  nonassessable shares of Common Stock as is determined by
                  dividing $1,000, plus the amount of any accrued and unpaid
                  dividends the Corporation elects to pay in Common Stock, by
                  the Conversion Price in effect at the time of conversion. The
                  Conversion Price at which shares of Common Stock shall be
                  deliverable upon conversion of Series A Preferred Stock
                  without the payment of additional consideration by the holder
                  thereof (the "Conversion Price") shall be the lower of (i)
                  105% of the average Closing Bid Price of the shares of Common
                  Stock for the five (5) trading days between November 2 through
                  November 6 ($5.71) or (ii) 80% of the average Closing Bid
                  Price of the shares of Common Stock for any five (5)
                  consecutive trading days during the twenty (20) consecutive
                  trading days immediately preceding the Series A Preferred
                  Stock Conversion Date (as hereinafter defined).

                           (b) At any time that the number of shares of Common
                  Stock issued (A) upon conversion of the Series A Preferred
                  Stock and (B) in lieu of dividend payments on the Series A
                  Preferred Stock, shall equal 630,000 (a "Common Stock
                  Redemption Event"), the Corporation shall (x) redeem, at a
                  price determined in accordance with Subsection G(1) of this
                  Section 7, all of the outstanding Series A Preferred Stock in
                  accordance with the provisions of Subsection G(2) or (y) call
                  a special meeting of its shareholders for the purpose of
                  approving the transactions contemplated by the Securities
                  Purchase Agreement, including the issuance of the Series A
                  Preferred Stock on the terms set forth therein, together with
                  any other approvals that shall be required so as to cause the
                  transactions contemplated by the Securities Purchase Agreement
                  to remain in compliance with the Rules and Regulations of The
                  Nasdaq Stock Market (including Rule 4320 of Nasdaq's Non-
                  Qualitative Designation Criteria in connection with
                  conversions of Series A Preferred Stock; such approvals are
                  referred to herein as the "Required Approvals"). The
                  Corporation shall determine within five (5) business days
                  following the receipt of a Notice of Conversion which of such
                  actions it shall take, and shall promptly furnish notice 

                                       27
<PAGE>
 
                  to each of the holders of Series A Preferred Stock as to such
                  determination, including, if applicable, a notice of
                  redemption. In no event shall the Corporation issue shares of
                  Common Stock upon conversion of, or in lieu of interest
                  payments on, the Series A Preferred Stock, after the
                  occurrence of a Common Stock Redemption Event until the
                  Required Approvals, if any, are obtained.

                           (c) If the Corporation elects to call a special
                  meeting of its shareholders pursuant to Subsection H(1)(b) of
                  this Section 7 to obtain the Required Approvals, the
                  Corporation shall use its best efforts to obtain such Required
                  Approvals within thirty (30) days of the Common Stock
                  Redemption Event (such thirty (30) day period is referred to
                  herein as an "Approval Period"). If the Corporation does not
                  obtain the Required Approvals within the Approval Period and
                  the Corporation receives a Notice of Conversion after the
                  termination of the Approval Period, the Corporation must
                  redeem, in accordance with this Subsection H of this Section
                  7, any shares of Series A Preferred Stock outstanding after
                  the Corporation has issued in excess of 630,000 shares of
                  Common Stock in connection with conversions of the Series A
                  Preferred Stock.

                           (d) If the Corporation elects, pursuant to this
                  Subsection H, to redeem the Series A Preferred Stock on the
                  occurrence of a Common Stock Redemption Event, it shall redeem
                  such Series A Preferred Stock at the price determined in
                  accordance with Subsection G(1) of this Section 7. If the
                  Corporation shall have elected, pursuant to this Subsection
                  H(1), to obtain the Required Approvals but shall not have done
                  so by the later of the occurrence of the Common Stock
                  Redemption Event or the expiration of the Approval Period, it
                  shall furnish a redemption notice to the Purchasers within
                  three (3) business days after the expiration of the Approval
                  Period.

                  (2) The Series A Preferred Stock Conversion Rights shall be
         exercised as follows:

                           (a) The Corporation will permit each holder of Series
                  A Preferred Stock to exercise its right to convert the Series
                  A Preferred Stock by faxing an executed and completed notice
                  of conversion (the "Notice of Conversion") to the Corporation,
                  and delivering within three (3) business days thereafter, the
                  original Notice of Conversion (and the certificates
                  representing the related shares of Series A Preferred Stock)
                  to the Corporation by hand delivery or by express courier,
                  duly endorsed. Each date on which a Notice of Conversion is
                  faxed to and received in accordance with the provisions hereof
                  shall be deemed a "Series A Preferred Stock Conversion Date."
                  The Corporation will transmit the certificates representing
                  the Common Stock issuable upon conversion of the Series A
                  Preferred Stock (together with certificates representing the
                  related shares of Series A Preferred Stock not so converted
                  and, if applicable, a check representing any fraction of a
                  share not converted) to such holder via express courier as
                  soon as practicable, but in all events no later than the later
                  to occur of (the "Delivery Date") (i) three (3) business days
                  after the Series A Preferred Stock Conversion Date, or (ii)
                  three (3) business days after receipt by the Corporation of
                  the original Notice of Conversion (and the certificates
                  representing the related shares of Series A Preferred Stock).
                  For purposes of this Section 7, such conversion of the Series
                  A Preferred Stock shall be deemed to have been made
                  immediately prior to the close of business on the Series A
                  Preferred Stock Conversion Date.

                           (b) In lieu of delivering physical certificates
                  representing the Common Stock issuable upon the conversion of
                  the Series A Preferred Stock, provided that the Corporation's
                  transfer agent is participating in the Depository

<PAGE>
 
                  Trust Corporation ("DTC") Fast Automated Securities Transfer
                  program, on the written request of a holder of Series A
                  Preferred Stock who shall have previously instructed such
                  holder's prime broker to confirm such request to the
                  Corporation's transfer agent, the Corporation shall use
                  commercially reasonable efforts to cause its transfer agent to
                  electronically transmit such Common Stock to such holder by
                  crediting the account of the holder's prime broker with DTC
                  through its Deposit Withdrawal Agent Commission system no
                  later than the applicable Delivery Date.

                           (c) The Corporation will at all times have authorized
                  and reserved for the purpose of issuance a sufficient number
                  of shares of Common Stock to provide for the conversion of the
                  Series A Preferred Stock. The Corporation will use its best
                  efforts at all times to maintain a number of shares of Common
                  Stock so reserved for issuance that is no less than one and
                  one-half (1.5) times the number that is then actually issuable
                  upon the conversion of the Series A Preferred Stock and the
                  exercise of the Warrants issued pursuant to that certain
                  Securities Purchase Agreement (the "Securities Purchase
                  Agreement") dates as of November 9, 1998, between the
                  Corporation and the purchasers named therein. Before taking
                  any action which would cause an adjustment reducing the
                  Conversion Price below the established par value of the shares
                  of Common Stock issuable upon conversion of the Series A
                  Preferred Stock, the Corporation will take any corporate
                  action which may, in the opinion of its counsel, be necessary
                  in order that the Corporation may validly and legally issue
                  fully paid and nonassessable shares of Common Stock at such
                  adjusted Conversion Price.

                           (d) All shares of Series A Preferred Stock, which
                  shall have been surrendered for conversion as herein provided
                  shall no longer be deemed to be outstanding, and all rights
                  with respect to such shares, including the rights, if any, to
                  receive dividends, notices and to vote, shall immediately
                  cease and terminate on the Series A Preferred Stock Conversion
                  Date, except only the right of the holders thereof to receive
                  shares of Common Stock in exchange therefor. Any shares of
                  Series A Preferred Stock so converted shall be retired and
                  canceled and shall not be reissued, and the Corporation may
                  from time to time take such appropriate action as may be
                  necessary to reduce the number of shares of authorized Series
                  A Preferred Stock accordingly.

                  (3) In the event of a liquidation of the Corporation, the
         Series A Preferred Stock Conversion Rights shall terminate at the close
         of business on the first full day preceding the date fixed for the
         payment of any amounts distributable on liquidation to the holders of
         the Series A Preferred Stock.

                  (4) If the conversion is in connection with an underwritten
         offer of securities registered pursuant to the Securities Act of 1933,
         as amended, the conversion may, at the option of any holder tendering
         Series A Preferred Stock for conversion, be conditioned upon the
         closing with the underwriter of the sale of securities pursuant to such
         offering, in which event the person(s) entitled to receive the Common
         Stock issuable upon such conversion of the Series A Preferred Stock
         shall not be deemed to have converted such Series A Preferred Stock
         until immediately prior to the closing of the sale of securities.

                  (5) At no time shall any holder (including any of its
         affiliates) of the Series A Preferred Stock convert such amount of
         Series A Preferred Stock as shall result in such Purchaser's (together
         with its affiliate's) ownership, after such conversion, exceeding 9.9%
         of the Corporation's outstanding Common Stock.

<PAGE>
 
                  (6) No fractional shares of Common Stock shall be issued upon
         conversion of the Preferred Stock. In lieu of fractional shares, the
         Corporation shall pay cash equal to such fraction multiplied by the
         then effective and applicable Conversion Price.

                  (7) The Corporation will not, by amendment of its Articles of
         Incorporation or through any reorganization, transfer of assets,
         consolidation, merger, dissolution, issue or sale of securities or any
         other voluntary action, avoid or seek to avoid the observance or
         performance of any of the terms to be observed or performed under this
         Subsection H by the Corporation, but will at all times in good faith
         assist in the carrying out of all the provisions of this Subsection H
         and in the taking of all such action as may be necessary or appropriate
         in order to protect the Series A Preferred Stock Conversion Rights of
         the holders of the Series A Preferred Stock against impairment.

                  (8) In the event (a) that the Corporation declares a dividend
         (or any other distribution) on its Common Stock payable in Common Stock
         or other securities of the Corporation, (b) that the Corporation
         subdivides or combines its outstanding shares of Common Stock, (c) of
         any reclassification of the Common Stock of the Corporation (other than
         a subdivision or combination of its outstanding shares of Common Stock
         or a stock dividend or stock distribution thereon), (d) of any
         consolidation or merger of the Corporation into or with another
         corporation, (e) of the sale of all or substantially all of the assets
         of the Corporation, or (f) of the involuntary or voluntary dissolution,
         liquidation or winding up of the Corporation, then the Corporation
         shall cause to be filed at its principal office or at the office of the
         transfer agent of the Preferred Stock, and shall cause to be mailed to
         each holder of the Preferred Stock at their last address as shown on
         the records of the Corporation or such transfer agent, at least ten
         (10) days prior to the record date specified in (i) below or twenty
         (20) days before the date specified in (ii) below, a notice stating

                           (i) the record date of such dividend, distribution,
                  subdivision or combination, or, if a record is not to be
                  taken, the date as of which the holders of Common Stock of
                  record to be entitled to such dividend, distribution,
                  subdivision or combination are to be determined, or

                           (ii) the date on which such reclassification,
                  consolidation, merger, sale, dissolution, liquidation or
                  winding up is expected to become effective, and the date as of
                  which it is expected that holders of Common Stock of record
                  shall be entitled to exchange their shares of Common Stock for
                  securities or other property deliverable upon such
                  reclassification, consolidation, merger, sale, dissolution or
                  winding up.

         I. Sinking Fund. There shall be no sinking fund for the payment of
dividends, or liquidation preferences on the Series A Preferred Stock or the
redemption of any shares thereof.

         J. Amendment. This Section 7 constitutes an agreement between the
Corporation and the holders of the Series A Preferred Stock. The Corporation
shall not amend this Section 7 or alter or repeal the preferences, rights,
powers or other terms of the Series A Preferred Stock so as to affect adversely
the Series A Preferred Stock, without the written consent or affirmative vote of
the holders of at least sixty-six and two- thirds percent (662/3%) of the then
outstanding shares of Series A Preferred Stock, given in writing or by vote at a
meeting, consenting or voting (as the case may be) separately as a class.

4. DELIVERY OF SHARE CERTIFICATES UPON EXERCISE. Following the exercise of this
Warrant in full or in part, within the time periods and in the manner provided
by Section 5(b) of the Securities Purchase Agreement, the Company, at its
expense (including the payment by it of any applicable issue taxes), will cause
to be issued in the name of and delivered to the Registered Holder hereof, or as
such Registered Holder (upon payment by such Registered Holder of any applicable
transfer taxes) may direct, a certificate or certificates for the number of
fully paid and nonassessable shares of Common Stock to which such Registered
Holder shall be entitled on such exercise, plus, in lieu of any fractional share
to which such Registered Holder would otherwise be entitled, cash equal to such
fraction multiplied by the then current market value of one full share of Common
Stock (as computed in accordance with Subsection 5.1(d) hereof).

5. ADJUSTMENT OF PURCHASE PRICE AND NUMBER OF SHARES OF COMMON STOCK.

    5.1. The Purchase Price hereof shall be subject to adjustment from time to
time as follows:

        (a) In case the Company shall (i) pay a dividend on its shares of Common
    Stock in Common Stock, (ii) subdivide its outstanding shares of Common Stock
    or (iii) combine its-outstanding shares of Common Stock into a smaller
    number of shares, then, in such an event, the Purchase Price in effect
    immediately prior thereto shall be adjusted proportionately so that the
    adjusted Purchase Price will bear the same relation to the Purchase Price in
    effect immediately prior to any such event as the total number of shares of
    Common Stock outstanding immediately prior any such event shall bear to the
    total number of shares of Common Stock outstanding immediately after to such
    event. An adjustment made pursuant to this Section 5.1(a) shall, (i) become
    effective retroactively immediately after the record date in the case of a
    dividend and shall (ii) become effective immediately-after the effective
    date in the case of a subdivision or combination. The Purchase Price, as so
    adjusted, shall be readjusted in the same manner upon the happening of any
    successive event or events described herein.

        (b) In case the Company shall distribute to all holders of its shares of
    Common Stock, Other Securities, evidences of its indebtedness or assets
    (excluding cash dividends or distributions) or purchase rights, options or
    warrants to subscribe for or purchase Other Securities, then in each such
    case, the Purchase Price in effect thereafter shall be determined by
    multiplying the Purchase Price in effect immediately prior thereto by a
    fraction, of which the numerator shall be the total number of outstanding
    shares of Common Stock multiplied by the current market price per share of
    Common Stock (as determined in accordance with the provisions of subdivision
    (c) below) on the record date mentioned below, less the fair market value as
    determined by the Board of Directors (whose determination shall be
    conclusive) of the Other Securities, assets or evidences of indebtedness so
    distributed or of such rights or warrants, and of which the denominator
    shall be the total number 2f outstanding shares of Common Stock multiplied
    by such current market price per share of Common Stock. Such adjustment
    shall be made whenever any such distribution is made and shall become
    effective retroactively immediately after the record date for the
    determination of shareholders entitled to receive such distribution.

        (c) For the purpose of any computation under subdivision (b) above, the
    current market price per share of Common Stock shall be deemed to be the
    closing price of the Company's shares of Common Stock on the date that the
    computation is made.

        (d) No adjustment of the Purchase Price shall be made if the amount of
    such adjustment shall be less than $.02 per share, but in such case, any
    adjustment that would otherwise be required then to be made shall be carried
    forward and shall be made at the time of and together with the next
    subsequent adjustment, which, together with any adjustment so carried
    forward, shall amount to not less than $.02 per share. In case the Company
    shall at any time issue shares of Common Stock by way of dividend on any
    class of stock of the Company or subdivide or combine the outstanding shares
    of Common Stock, said amount of $.02 per share (as theretofore increased or
    decreased, if the same amount shall have been adjusted in accordance with
    the 
<PAGE>
 
    provisions of this subparagraph) shall forthwith be proportionately
    increased in the case of a combination or decreased in the case of such a
    subdivision or stock dividend so as to appropriately reflect the same.

    5.2. Upon each adjustment of the Purchase Price pursuant to subdivisions (a)
and (b) of Section 5.1, the number of shares of Common Stock purchasable upon
exercise of this Warrant-shall be adjusted to the number of shares of Common
Stock, calculated to the nearest one hundredth of a share, obtained by
multiplying the number of shares of Common Stock purchasable immediately prior
to such adjustment upon the exercise of this Warrant Certificate by the Purchase
Price in effect prior to such adjustment and dividing the product so obtained by
the new Purchase Price.

    5.3. In the event of any capital reorganization of the Company, or of any
reclassification of the shares of Common Stock, this Warrant shall be
exercisable after such capital reorganization or reclassification upon the terms
and conditions specified in this Warrant, for the number of shares of stock or
other securities which the shares of Common Stock issuable (at the time of such
capital reorganization or reclassification) upon exercise of this Warrant would
have been entitled to receive upon such capital reorganization or
reclassification if such exercise had taken place immediately prior to such
action. The subdivision or combination of shares of Common Stock at any time
outstanding into a greater or lesser number of shares of Common Stock shall not
be deemed to be a reclassification of the shares of Common Stock of the Company
for the purposes of this Subsection 5.3.

    5.4. Whenever the Purchase Price is adjusted as herein provided, the Company
shall compute the adjusted Purchase Price in accordance with Subsection 5.1 and
shall prepare a certificate signed by its Chief Financial Officer and any other
executive officer setting forth the adjusted Purchase Price, and showing in
reasonable detail the method of such adjustment and the fact requiring the
adjustment and upon which such calculation is based and such certificate shall
forthwith be forwarded to the Registered Holder.

    5.5. The form of this Warrant need not be changed because of any change in
the Purchase Price pursuant to this Section 5 and any Warrant issued after such
change may state the same Purchase Price and the same number of shares of Common
Stock as are stated in this Warrant as initially issued.

6. ADJUSTMENT FOR REORGANIZATION, CONSOLIDATION, MERGER, ETC.

    6.1. MERGER, ETC. In case at any time or from time to time after the date of
issuance of this Warrant, the Company shall (a) effect a reorganization, (b)
consolidate with or merge into any other person or (c) transfer all or
substantially all of its properties or assets to any other person under any plan
or arrangement contemplating the dissolution of the Company within three (3)
years from the date of such transfer (any such transaction being hereinafter
sometimes referred to as a "Reorganization"), then, in each such case, the
Registered Holder of this Warrant, upon the exercise hereof as provided in
Section 3 at any time after the consummation or effective date of such
Reorganization (the "Effective Date"), shall receive, in lieu of the shares of
Common Stock issuable on such exercise prior to such consummation or such
Effective Date, the stock and other securities and property (including cash) to
which such Registered Holder would have been entitled upon such consummation or
in connection with such dissolution, as the case may be, if such Registered
Holder had so exercised this Warrant, immediately prior thereto (all subject to
further adjustment thereafter as provided in Section 5). The Company shall not
effect a transaction of the type described in clause (b) or (c) above unless
upon or prior to the consummation thereof, the Company's successor corporation,
or if the Company shall be the "surviving company in any such Reorganization but
is not the issuer of the shares of stock, securities or other property to be
delivered to the holders of the Company's outstanding shares of Common Stock at
the effective time thereof, then such issuer, shall assume in writing the
obligation hereunder to deliver to the Registered Holder of this Warrant such
shares of stock, securities, cash or other property as such holder shall be
entitled to purchase in accordance with the provisions hereof

    6.2. DISSOLUTION. Except as otherwise expressly provided in Subsection 6.1,
in the event of any dissolution of the Company following the transfer of all or
substantially all of its properties or assets, the Company, prior to such

other securities and property (including cash, where applicable) receivable by
the holders of the Warrants after the effective date of such

principal office in New York City, as trustee for the holder or holders of the
Warrants.

    6.3. CONTINUATION OF TERMS. Except as otherwise expressly provided in
Subsection 6.1, upon any reorganization, consolidation, merger or transfer (and
any dissolution following any transfer) referred to in this Section 6, this
Warrant shall continue in full force and effect and the terms hereof shall be
applicable to the shares of stock and other securities and property receivable
on the exercise of this Warrant after the consummation of such reorganization,
consolidation or merger or the effective date of dissolution following any such
transfer, as the case may be, and shall be binding upon the issuer of any such
stock or other securities, including, in the case of any such transfer, the
person acquiring all or substantially all of the properties or assets of the
Company, whether or not such person shall have expressly assumed the terms of
this Warrant. 

7. NO DILUTION OR IMPAIRMENT. The Company will not, by amendment of its
Certificate of Incorporation or By-laws, or through any reorganization, transfer
of assets, consolidation, merger, dissolution, issue or sale of securities or
any other voluntary action, avoid or seek to avoid the observance or performance

Shares shall be subject to the provisions of Section 5 of the Securities

prior to the Expiration Time by surrendering this Warrant, with the form of

Company in the manner set forth in Section 5 of the Securities Purchase

by certified or official bank check payable to the order of the Company, in the
amount obtained by multiplying the number of Shares of Common Stock called for
on the face of this Warrant (without giving effect to any adjustment therein) by
the Initial Purchase Price.

    3.2. PARTIAL EXERCISE. This Warrant may be exercised in part by surrender of
this Warrant in the manner provided in Subsection 3.1, except that the exercise
price shall be calculated by multiplying (a) the number of shares of Common
Stock as shall be designated by he holder in the subscription at the end hereof
by (b).the Initial Purchase Price. On any such partial exercise, subject to the
provisions of Section 2 hereof, the Company, at its expense will forthwith issue
and deliver to or upon the order of the Registered Holder hereof a new Warrant
or Warrants of like tenor, in the name of the Registered Holder hereof or as
such Registered Holder may request, calling in the aggregate on the face or
faces thereof for the number of shares of Common Stock (without giving effect to

face of this Warrant minus the number of such shares designated by the
Registered Holder in the applicable Election to Purchase.

    3.3. COMPANY ACKNOWLEDGMENT. The Company will, at the time of the exercise,
exchange or transfer of this Warrant, upon the request of the Registered Holder
hereof, acknowledge in writing its continuing obligation to afford to such

right to registration of the Company's shares of Common Stock) to which such
Registered Holder or transferee shall continue to be entitled after such
exercise, exchange or transfer in accordance with the provisions of this

of the Company to afford to such Registered Holder or transferee any such
rights.

4. DELIVERY OF SHARE CERTIFICATES UPON EXERCISE. Following the exercise of this
Warrant in full or in part, within the time periods and in the manner provided
by Section 5(b) of the Securities Purchase Agreement, the Company, at its
expense (including the payment by it of any applicable issue taxes), will cause
to be issued in the name of and delivered to the Registered Holder hereof, or as
such Registered Holder (upon payment by such Registered Holder of any applicable
transfer taxes) may direct, a certificate or certificates for the number of
fully paid and nonassessable shares of Common Stock to which such Registered
Holder shall be entitled on such exercise, plus, in lieu of any fractional share
to which such Registered Holder would otherwise be entitled, cash equal to such
fraction multiplied by the then current market value of one full share of Common
Stock (as computed in accordance with Subsection 5.1(d) hereof).

5. ADJUSTMENT OF PURCHASE PRICE AND NUMBER OF SHARES OF COMMON STOCK.

    5.1. The Purchase Price hereof shall be subject to adjustment from time to
time as follows:

        (a) In case the Company shall (i) pay a dividend on its shares of Common
    Stock in Common Stock, (ii) subdivide its outstanding shares of Common Stock
    or (iii) combine its-outstanding shares of Common Stock into a smaller
    number of shares, then, in such an event, the Purchase Price in effect
    immediately prior thereto shall be adjusted proportionately so that the
    adjusted Purchase Price will bear the same relation to the Purchase Price in
    effect immediately prior to any such event as the total number of shares of
    Common Stock outstanding immediately prior any such event shall bear to the
    total number of shares of Common Stock outstanding immediately after to such
    event. An adjustment made pursuant to this Section 5.1(a) shall, (i) become
    effective retroactively immediately after the record date in the case of a
    dividend and shall (ii) become effective immediately-after the effective
    date in the case of a subdivision or combination. The Purchase Price, as so
    adjusted, shall be readjusted in the same manner upon the happening of any
    successive event or events described herein.

        (b) In case the Company shall distribute to all holders of its shares of
    Common Stock, Other Securities, evidences of its indebtedness or assets
    (excluding cash dividends or distributions) or purchase rights, options or
    warrants to subscribe for or purchase Other Securities, then in each such
    case, the Purchase Price in effect thereafter shall be determined by
    multiplying the Purchase Price in effect immediately prior thereto by a
    fraction, of which the numerator shall be the total number of outstanding
    shares of Common Stock multiplied by the current market price per share of
    Common Stock (as determined in accordance with the provisions of subdivision
    (c) below) on the record date mentioned below, less the fair market value as
    determined by the Board of Directors (whose determination shall be
    conclusive) of the Other Securities, assets or evidences of indebtedness so
    distributed or of such rights or warrants, and of which the denominator
    shall be the total number 2f outstanding shares of Common Stock multiplied
    by such current market price per share of Common Stock. Such adjustment
    shall be made whenever any such distribution is made and shall become
    effective retroactively immediately after the record date for the
    determination of shareholders entitled to receive such distribution.

        (c) For the purpose of any computation under subdivision (b) above, the
    current market price per share of Common Stock shall be deemed to be the
    closing price of the Company's shares of Common Stock on the date that the
    computation is made.

        (d) No adjustment of the Purchase Price shall be made if the amount of
    such adjustment shall be less than $.02 per share, but in such case, any
    adjustment that would otherwise be required then to be made shall be carried
    forward and shall be made at the time of and together with the next
    subsequent adjustment, which, together with any adjustment so carried
    forward, shall amount to not less than $.02 per share. In case the Company
    shall at any time issue shares of Common Stock by way of dividend on any
    class of stock of the Company or subdivide or combine the outstanding shares
    of Common Stock, said amount of $.02 per share (as theretofore increased or
    decreased, if the same amount shall have been adjusted in accordance with
    the 
<PAGE>
 
    provisions of this subparagraph) shall forthwith be proportionately
    increased in the case of a combination or decreased in the case of such a
    subdivision or stock dividend so as to appropriately reflect the same.

    5.2. Upon each adjustment of the Purchase Price pursuant to subdivisions (a)
and (b) of Section 5.1, the number of shares of Common Stock purchasable upon
exercise of this Warrant-shall be adjusted to the number of shares of Common
Stock, calculated to the nearest one hundredth of a share, obtained by
multiplying the number of shares of Common Stock purchasable immediately prior
to such adjustment upon the exercise of this Warrant Certificate by the Purchase
Price in effect prior to such adjustment and dividing the product so obtained by
the new Purchase Price.

    5.3. In the event of any capital reorganization of the Company, or of any
reclassification of the shares of Common Stock, this Warrant shall be
exercisable after such capital reorganization or reclassification upon the terms
and conditions specified in this Warrant, for the number of shares of stock or
other securities which the shares of Common Stock issuable (at the time of such
capital reorganization or reclassification) upon exercise of this Warrant would
have been entitled to receive upon such capital reorganization or
reclassification if such exercise had taken place immediately prior to such
action. The subdivision or combination of shares of Common Stock at any time
outstanding into a greater or lesser number of shares of Common Stock shall not
be deemed to be a reclassification of the shares of Common Stock of the Company
for the purposes of this Subsection 5.3.

    5.4. Whenever the Purchase Price is adjusted as herein provided, the Company
shall compute the adjusted Purchase Price in accordance with Subsection 5.1 and
shall prepare a certificate signed by its Chief Financial Officer and any other
executive officer setting forth the adjusted Purchase Price, and showing in
reasonable detail the method of such adjustment and the fact requiring the
adjustment and upon which such calculation is based and such certificate shall
forthwith be forwarded to the Registered Holder.

    5.5. The form of this Warrant need not be changed because of any change in
the Purchase Price pursuant to this Section 5 and any Warrant issued after such
change may state the same Purchase Price and the same number of shares of Common
Stock as are stated in this Warrant as initially issued.

6. ADJUSTMENT FOR REORGANIZATION, CONSOLIDATION, MERGER, ETC.

    6.1. MERGER, ETC. In case at any time or from time to time after the date of
issuance of this Warrant, the Company shall (a) effect a reorganization, (b)
consolidate with or merge into any other person or (c) transfer all or
substantially all of its properties or assets to any other person under any plan
or arrangement contemplating the dissolution of the Company within three (3)
years from the date of such transfer (any such transaction being hereinafter
sometimes referred to as a "Reorganization"), then, in each such case, the
Registered Holder of this Warrant, upon the exercise hereof as provided in
Section 3 at any time after the consummation or effective date of such
Reorganization (the "Effective Date"), shall receive, in lieu of the shares of
Common Stock issuable on such exercise prior to such consummation or such
Effective Date, the stock and other securities and property (including cash) to
which such Registered Holder would have been entitled upon such consummation or
in connection with such dissolution, as the case may be, if such Registered
Holder had so exercised this Warrant, immediately prior thereto (all subject to
further adjustment thereafter as provided in Section 5). The Company shall not
effect a transaction of the type described in clause (b) or (c) above unless
upon or prior to the consummation thereof, the Company's successor corporation,
or if the Company shall be the "surviving company in any such Reorganization but
is not the issuer of the shares of stock, securities or other property to be
delivered to the holders of the Company's outstanding shares of Common Stock at
the effective time thereof, then such issuer, shall assume in writing the
obligation hereunder to deliver to the Registered Holder of this Warrant such
shares of stock, securities, cash or other property as such holder shall be
entitled to purchase in accordance with the provisions hereof

    6.2. DISSOLUTION. Except as otherwise expressly provided in Subsection 6.1,
in the event of any dissolution of the Company following the transfer of all or
substantially all of its properties or assets, the Company, prior to such
dissolution, shall at its expense deliver or cause to be delivered the stock and
other securities and property (including cash, where applicable) receivable by
the holders of the Warrants after the effective date of such 
<PAGE>
 
dissolution pursuant to this Section 6 to a bank or trust company having its
principal office in New York City, as trustee for the holder or holders of the
Warrants.

    6.3. CONTINUATION OF TERMS. Except as otherwise expressly provided in
Subsection 6.1, upon any reorganization, consolidation, merger or transfer (and
any dissolution following any transfer) referred to in this Section 6, this
Warrant shall continue in full force and effect and the terms hereof shall be
applicable to the shares of stock and other securities and property receivable
on the exercise of this Warrant after the consummation of such reorganization,
consolidation or merger or the effective date of dissolution following any such
transfer, as the case may be, and shall be binding upon the issuer of any such
stock or other securities, including, in the case of any such transfer, the
person acquiring all or substantially all of the properties or assets of the
Company, whether or not such person shall have expressly assumed the terms of
this Warrant.

7. NO DILUTION OR IMPAIRMENT. The Company will not, by amendment of its
Certificate of Incorporation or By-laws, or through any reorganization, transfer
of assets, consolidation, merger, dissolution, issue or sale of securities or
any other voluntary action, avoid or seek to avoid the observance or performance
of any of the terms of the Warrants, but will at all times in ..good faith

action as may be necessary or appropriate in order to protect the rights of the
holders of the Warrants, as specified herein and in the Securities Purchase

exercise of the Warrants above the amount payable therefor on such exercise, and

with respect to any class of the Common Stock without effecting an equivalent

time of any holder of a Warrant, furnish to such holder a like certificate
setting forth the Purchase Price and the number and type of Shares at the time
in effect and showing how it was calculated.

9. NOTICE OF RECORD DATE. In case of

        (a) any taking by the Company of a record of the holders of any class of
    its securities for the purpose of determining the holders thereof who are

         RE: Form S-3 Registration Statement

Ladies/Gentlemen:

         This opinion is furnished in connection with the registration, pursuant
to the Securities Act of 1933, as amended, of 78,240 issued and outstanding
shares of common stock, no par value (the "Outstanding Shares"), of Online
System Services, Inc. (the "Company" or "OSS") to be sold from time to time by
various selling shareholders for their own account and up to 1,665,260 shares of
common stock, no par value (the "Issuable Shares"), of OSS issuable upon (i)
conversion of the Company's 10% Preferred Stock (the "10% Preferred Stock"),
(ii) conversion of the Company's Series A Preferred Stock (the "Series A
Preferred Stock"), and (iii) exercise of outstanding transferable warrants of
OSS which may sold from time to time by various selling shareholders for their
own account.

         We have acted as counsel to the Company in connection with the
preparation of the Form S-3 Registration Statement (the "Registration
Statement"). We have examined the Articles of Incorporation, as amended, the
Bylaws of the Company, such records of proceedings of the Company as we deemed
material and such other certificates, records and documents as we considered
necessary for the purposes of this opinion.

         Based on the foregoing, we are of the opinion that (a) the Outstanding
Shares are legally issued, fully paid and non-assessable securities of the
Company and (b) the Issuable Shares (up to a maximum of 1,665,260 shares) will
be, when issued, legally issued, fully paid and non-assessable securities of the
Company. We understand that this opinion is to be issued in connection with the
Registration Statement. We consent to a filing of a copy of this opinion with
the Registration Statement.

                                            Very truly yours,

                                            GRAY, PLANT, MOOTY,
