    This Prospectus contains "forward-looking statements," as defined under
Section 27A of the Securities Act of 1933, as amended (the "Securities Act").
Forward-looking statements are statements other than historical information or
statements of current condition. Some forward looking statements may be
identified by use of such terms as "believes," "anticipates," "intends" or
"expects." These forward-looking statements relate to plans, objectives and
expectations for future operations of STAR. In light of the risks and
uncertainties inherent in all such projected operation matters, the inclusion of
forward-looking statements in this Prospectus should not be regarded as a
representation by the Company or any other person that the objectives or plans
of the Company will be achieved or that any of the Company's operating
expectations will be realized. Revenues and results of operations are difficult
to forecast and could differ materially from those projected in the
forward-looking statements contained in this Prospectus. Forward-looking
statements may be deemed to include those set forth in "Prospectus Summary,"
regarding the Company's introduction into service of various international
gateway switches, commitments to acquire undersea cables and various aspects of
the Company's strategy. Such forward-looking statements may be deemed to include
statements in "Management's Discussion and Analysis of Financial Condition and
Results of Operations," regarding the Company's strategy to lower its cost of
services and improve its gross margin and its belief that price declines may be
offset in part by increased calling volumes and decreased costs and its belief
in the sufficiency of capital resources. Forward-looking statements in
"Business" may be deemed to include projected growth in international
telecommunications traffic, the Company's strategy of marketing its services to
foreign-based long distance providers, expanding its U.S. and developing
European switching capabilities, and expanding into commercial markets. Actual
results could differ from those projected in any forward-looking statements for
the reasons detailed in the "Risk Factors" section of the Prospectus, beginning
on page 7, or elsewhere in this Prospectus. The Company undertakes no obligation
to release publicly the results of any future revisions it may make to any of
its forward-looking statements to reflect events or circumstances after the date
hereof, to reflect the occurrence of unanticipated events or to reflect any
change in the Company's operating strategy.

                                  THE COMPANY
 
    STAR Telecommunications, Inc. ("STAR" or the "Company") is an emerging
multinational carrier focused primarily on the international long distance
market. The Company offers highly reliable, low-cost switched voice services on
a wholesale basis, primarily to U.S.-based long distance carriers. STAR provides
international long distance service to approximately 220 foreign countries
through a flexible network comprised of various foreign termination
relationships, international gateway switches, leased and owned transmission
facilities and resale arrangements with long distance providers. The Company has
grown its revenues rapidly by capitalizing on the deregulation of international
telecommunications markets, combining sophisticated information systems with
flexible routing and leveraging management's industry expertise. STAR has
increased its revenues from $46.3 million in 1995 to $376.2 million in 1997.
 
    The Company serves the large and growing international long distance
telecommunications market. According to industry sources, worldwide gross
revenues in this market were over $60 billion in 1996 and the volume of
international traffic on the public telephone network is expected to grow at a
compound annual growth rate of approximately 13% from 1996 through the year
2000.
 
    STAR markets its services to large global carriers seeking lower rates and
high quality overflow capacity, as well as to small and medium-sized long
distance companies that do not have the critical mass to invest in their own
international transmission facilities or to obtain volume discounts from the
larger facilities-based carriers. During the fourth quarter of 1997, the Company
provided switched international long distance services to 105 customers and
currently provides these services to nine of the top forty global carriers. The
Company has also recently focused on building a customer base overseas,
particularly in Europe, and has opened offices in Dusseldorf, Frankfurt, Hamburg
and Munich, Germany and London, England. In addition, STAR has begun to market
its international long distance services directly to certain commercial
customers in the U.S. and overseas.
 
    The Company currently operates international gateway switching facilities in
New York, Los Angeles, Dallas and London, England. In 1998, the Company plans to
put into service switches in Atlanta, Chicago, Miami and Seattle; Dusseldorf,
Frankfurt, Hamburg and Munich, Germany; Paris, France; and Tokyo, Japan. STAR's
switching facilities are linked to a proprietary reporting system, which the
Company believes provides it with a competitive advantage by permitting
management on a real-time basis to determine the most cost-effective termination
alternatives, monitor customer usage and manage gross margins by route. The
Company holds ownership positions in a number of digital undersea fiber optic
cables, has recently added capacity on the TPC-5 undersea fiber optic cable
system and has entered into commitments to acquire transmission capacity on
three additional undersea fiber optic cable systems, Gemini, AC-1 and China-US.

                                    STRATEGY
 
    The Company's objective is to be a leading provider of highly reliable,
low-cost switched international long distance services on a wholesale basis to
U.S. and foreign-based telecommunications companies, as well as on a retail
basis to commercial customers. Key elements of the Company's strategy include
the following:
 
    CAPITALIZE ON PROJECTED INTERNATIONAL LONG DISTANCE GROWTH.  The Company
believes that the international long distance market provides attractive
opportunities due to its higher revenue and profit per minute, and greater
projected growth rate as compared to the domestic long distance market. The
Company targets international markets with high volumes of traffic, relatively
high rates per minute and prospects for deregulation and privatization. The
Company believes that the ongoing trend toward deregulation and privatization
will create new opportunities for the Company in international markets. Although
the Company has focused to date primarily on providing services for U.S.-based
long distance providers, the Company also intends to expand the international
long distance services it offers to foreign-based long distance providers.
 
    LEVERAGE TRAFFIC VOLUME TO REDUCE COSTS.  The Company continues to focus on
building its volume of international long distance traffic. Higher traffic
volumes strengthen the Company's negotiating position with vendors, customers
and potential foreign partners, which allows the Company to lower its costs of
service. In addition, higher traffic volumes on particular routes allow the
Company to lower its cost of services on these routes by transitioning from
acquiring capacity on a variable cost per minute basis to fixed cost
arrangements such as longer-term capacity agreements with major carriers,
long-term leases and ownership of facilities.
 
    LEVERAGE INFORMATION SYSTEMS AND SWITCHING CAPABILITIES.  The Company
leverages its sophisticated information systems to analyze its routing
alternatives, and select the most cost-effective routing from among the Company
owned facilities, network of resale arrangements with other long distance
providers, operating agreements and alternative termination relationships. The
Company has invested significant resources in the development of software to
track specific usage information by customer and revenue and cost information on
specific routes on a daily basis. The Company's information systems are critical
components in managing its customer and vendor relationships, routing traffic to
the most cost-effective alternative, and targeting its marketing efforts.
 
    MAINTAIN HIGH QUALITY.  The Company believes that reliability, call
completion rates, voice quality, rapid set up time and a high level of customer
and technical support are key factors evaluated by U.S. and foreign-based
telecommunications companies and large corporate customers in selecting a
carrier for their international traffic. The Company's state-of-the-art
switching equipment is fully compliant with international C-7 and domestic SS-7
signaling standards. STAR strives to provide a consistently high level of
customer and technical support and has technical support personnel at its
switching facilities 24 hours per day, seven days per week to assist its
customers and to continually monitor network operations.
 
    EXPAND INTO COMMERCIAL MARKET.  The Company plans to expand into niche
commercial markets in the U.S. and in other deregulating countries where it
believes it can leverage its international network and where the customer base
has a significant international calling pattern. The Company recently acquired
L.D. Services, Inc. ("LDS") and intends to acquire United Digital Network, Inc.
("UDN"). The Company is using the LDS telemarketing sales force to target small
commercial customers in ethnic markets to increase traffic to Mexico and Latin
America. Additionally, STAR intends to use UDN's network of independent sales
agents to target medium-sized commercial customers with a demand for
international calling services at competitive rates. Finally, the Company plans
to use its direct sales forces to target larger commercial customers,
concentrating at first on potential customers in Los Angeles and New York. With
respect to the offering of commercial services abroad, the Company initially
intends to focus on Germany, the U.K. and selected European cities where
competition for commercial customers is less mature.
 
                                       4
<PAGE>
    GROWTH THROUGH ACQUISITIONS.  The Company actively pursues opportunities to
enhance its business through strategic and synergistic acquisitions. These
acquisitions may focus on entering new territories, enlarging the Company's
presence in an existing territory, adding capacity or expanding into new market
segments, such as the commercial market. In addition to expanding its revenue
base, the Company plans to realize operating efficiencies by integrating
newly-acquired operations into the Company's billing, tracking and other
systems. On November 30, 1997, the Company acquired LDS, a long distance
provider focusing on small commercial customers throughout the United States,
for approximately 849,000 shares of Common Stock. On March 10, 1998, the Company
acquired T-One Corp. ("T-One"), an international wholesale long distance
provider, for 1,353,000 shares of Common Stock. On November 19, 1997, the
Company entered into an agreement to acquire UDN, a commercial long distance
provider. The acquisition of UDN is subject to approval by UDN's stockholders
and to various regulatory approvals. Assuming the receipt of all necessary
approvals, STAR expects to consummate the UDN acquisition in the second quarter
of 1998 for approximately 800,000 shares of Common Stock. Each of these

    THE FOLLOWING RISK FACTORS SHOULD BE CONSIDERED CAREFULLY IN ADDITION TO THE
OTHER INFORMATION CONTAINED IN THIS PROSPECTUS BEFORE PURCHASING THE SHARES OF
COMMON STOCK OFFERED HEREBY. THIS PROSPECTUS CONTAINS, IN ADDITION TO HISTORICAL
INFORMATION, "FORWARD-LOOKING STATEMENTS" WITHIN THE MEANING OF SECTION 27A OF
THE SECURITIES ACT THAT INVOLVE RISKS AND UNCERTAINTIES. THE COMPANY'S ACTUAL
RESULTS MAY DIFFER MATERIALLY FROM THOSE PROJECTED IN THE FORWARD-LOOKING
STATEMENTS. FACTORS THAT MAY CAUSE SUCH A DIFFERENCE INCLUDE, BUT ARE NOT
LIMITED TO, THOSE SET FORTH BELOW AND ELSEWHERE IN THIS PROSPECTUS. SEE
"DESCRIPTION OF FORWARD-LOOKING STATEMENTS."
 
OPERATING RESULTS SUBJECT TO SIGNIFICANT FLUCTUATIONS
 
    The Company's quarterly operating results are difficult to forecast with any
degree of accuracy because a number of factors subject these results to
significant fluctuations. As a result, the Company believes that
period-to-period comparisons of its operating results are not necessarily
meaningful and should not be relied upon as indications of future performance.
 
    FACTORS INFLUENCING OPERATING RESULTS, INCLUDING REVENUES, COSTS AND
MARGINS.  The Company's revenues, costs and expenses have fluctuated
significantly in the past and are likely to continue to fluctuate significantly
in the future as a result of numerous factors. The Company's revenues in any
given period can vary due to factors such as call volume fluctuations,
particularly in regions with relatively high per-minute rates; the addition or
loss of major customers, whether through competition, merger, consolidation or
otherwise; the loss of economically beneficial routing options for the
termination of the Company's traffic; financial difficulties of major customers;
pricing pressure resulting from increased competition; and technical
difficulties with or failures of portions of the Company's network that impact
the Company's ability to provide service to or bill its customers. The Company's
cost of services and operating expenses in any given period can vary due to
factors such as fluctuations in rates charged by carriers to terminate the
Company's traffic; increases in bad debt expense and reserves; the timing of
capital expenditures, and other costs associated with acquiring or obtaining
other rights to switching and other transmission facilities; changes in the
Company's sales incentive plans; and costs associated with changes in staffing
levels of sales, marketing, technical support and administrative personnel. In
addition, the Company's operating results can vary due to factors such as
changes in routing due to variations in the quality of vendor transmission
capability; loss of favorable routing options; the amount of, and the accounting
policy for, return traffic under operating agreements; actions by domestic or
foreign regulatory entities; the level, timing and pace of the Company's
expansion in international and commercial markets; and general domestic and
international economic and political conditions. Further, a substantial portion
of transmission capacity used by the Company is obtained on a variable, per
minute and short term basis, subjecting the Company to the possibility of
unanticipated price increases and service cancellations. Since the Company does
not generally have long term arrangements for the purchase or resale of long
distance services, and since rates fluctuate significantly over short periods of
time, the Company's gross margins are subject to significant fluctuations over
short periods of time. The Company's gross margins also may be negatively
impacted in the longer term by competitive pricing pressures.
 
    EXAMPLES OF FACTORS AFFECTING OPERATING RESULTS.  The Company has in the
past encountered significant difficulties in the collection of accounts
receivable from certain of its customers. For example, in the fourth quarter of
1996 and the first quarter of 1997, Hi-Rim Communications, Inc. ("Hi-Rim"),
formerly one of the Company's major customers and Cherry Communications, Inc.
("CCI"), the Company's largest customer in 1996 experienced financial
difficulties and were unable to pay in full, on a timely basis, outstanding
accounts receivable. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations." In early 1997, the Company implemented
more stringent credit policies and monitoring systems. There can be no
assurance, however, that if the Company experiences similar difficulties in the
collection of future accounts receivable from its customers, the Company's
financial condition and results of operations would not be materially adversely
affected.
 
                                       7
<PAGE>
ABILITY TO CONTINUE AND MANAGE GROWTH; COMMERCIAL MARKET
 
    The Company has increased revenues from $46.3 million in 1995 to $376.2
million in 1997, with revenues increasing in each of the last ten quarters. Such
growth should not be considered indicative of future revenue growth or operating
results. If revenue levels fall below expectations, net income is likely to be
disproportionately adversely affected because a proportionately smaller amount
of the Company's operating expenses varies with its revenues. This effect is
likely to increase as a greater percentage of the Company's cost of services are
associated with owned and leased facilities. There can be no assurance that the
Company will be able to achieve or maintain profitability on a quarterly or
annual basis in the future. It is likely that in some future quarter the
Company's operating results will be below the expectations of public market
analysts and investors. In such event, the price of the Company's Common Stock
would likely be materially adversely affected. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations."
 
    As part of the Company's significant revenue growth, it has expanded, and
plans to continue to expand, the number of its employees and the geographic
scope of its operations. Additionally, an important component of the Company's
strategy is to grow and expand through acquisition. These factors have resulted,
and will continue to result, in increased responsibilities for management
personnel and have placed, and will continue to place, increased demands upon
the Company's operating and financial systems, which may lead to unanticipated
costs and divert management's attention from day-to-day operations. The Company
may also be required to attract, train and retain additional highly qualified
management, technical, sales and marketing and customer support personnel. The
process of locating such personnel with the combination of skills and attributes
required to implement the Company's strategy is often lengthy. The inability to
attract and retain additional qualified personnel could materially and adversely
affect the Company. The Company expects that its expansion into foreign
countries will lead to increased financial and administrative demands, such as
increased operational complexity associated with expanded network facilities,
administrative burdens associated with managing an increasing number of foreign
subsidiaries and relationships with foreign partners and expanded treasury
functions to manage foreign currency risks. The Company's accounting systems and
policies have been developed as the Company has experienced significant growth.
There can be no assurance that the Company's personnel, systems, procedures and
controls will be adequate to support the Company's future operations. See "--
Dependence on Key Personnel," "Business--Employees" and "Management."
 
    With the acquisition of LDS, STAR began providing service to the commercial
market, which is more labor intensive than the wholesale market, and as a result
has higher overhead costs. The Company also may be required to update and
improve its billing systems and procedures and/or hire new management personnel
to handle the demands of the commercial market. There can be no assurance that
the Company will be able to effectively manage the costs of and risks associated
with its expansion into the commercial market.
 
RISKS INHERENT IN ACQUISITION STRATEGY
 
    An important component to the Company's strategy is to grow and expand
through acquisitions. This growth strategy is dependent on the continued
availability of suitable acquisition candidates and subjects the Company to a
number of risks. The Company has recently completed two acquisitions, LDS on
November 30, 1997, and T-One on March 10, 1998. Additionally, on November 19,
1997, the Company entered into an agreement to acquire UDN. The acquisition of
UDN is subject to approval of UDN's stockholders and to various regulatory
approvals, and the Company may not complete this acquisition. These acquisitions
have placed significant demands on the Company's financial and management
resources, as the process for integrating acquired operations presents a
significant challenge to the Company's management and may lead to unanticipated
costs or a diversion of management's attention from day-to-day operations. There
can be no assurance that the Company will be able to successfully integrate
these acquisitions or any other acquisitions made by the Company in the future
into Company
 
                                       8
<PAGE>
operations. Integrating acquisitions may require integration of financial and
call routing systems, network and other physical facilities and personnel.
Difficulties in integrating these and other acquisitions can cause system
degradation, added costs and loss of personnel or customers. Additionally, the
Company may incur unknown liabilities despite management's efforts to
investigate the operations of the acquired business. The impact of these risks,
and other risks arising as a result of STAR's acquisition strategy, could
adversely affect the Company's operating results.
 
RISKS ASSOCIATED WITH GROWTH OF TELECOMMUNICATIONS NETWORK AND CUSTOMER BASE
 
    Historically, the Company has relied primarily on leased transmission
capacity for the delivery of its telecommunications services. The Company's
telecommunications expenses have in the past primarily been variable, based upon
minutes of use, consisting largely of payments to other long distance carriers,
customer/carrier interconnect charges, leased fiber circuit charges and switch
facility costs. During 1997, however, the Company made considerable capital
expenditures in order to expand its network, and intends to continue to do so in
the future. See "Use of Proceeds" and "Business--Network." Although the
Company's strategy is to seek to establish significant traffic volumes prior to
investing in fixed-cost facilities, the development of such facilities entails
significant costs and prior planning, which are based in part on the Company's
expectations concerning future revenue growth and market developments. As the
Company expands its network and the volume of its network traffic, its cost of
revenues will increasingly consist of fixed costs arising from the ownership and
maintenance of its switches and undersea fiber optic cables. While the Company
believes that in the long-term these investments will allow it to reduce its
cost of service and to enhance its service offerings, in the short-term, costs
increases and a decrease in the Company's operating margins may occur. If the
Company's traffic volume were to decrease, or fail to increase to the extent
expected or necessary to make efficient use of its network, the Company's costs
as a percentage of revenues could increase significantly, which could have a
material adverse effect on the Company's business, financial condition or
results of operations.
 
    In addition, the Company's business depends in part on its ability to obtain
transmission facilities on a cost-effective basis. Because undersea fiber optic
cables typically take several years to plan and construct, carriers generally
make investments well in advance, based on a forecast of anticipated traffic.
Therefore, the Company's operations are subject to the risk that it will not
adequately anticipate the amount of traffic over its network, and may not
procure sufficient cable capacity or network equipment in order to ensure the
cost-effective transmission of customer traffic. Although the Company
participates in the planning of undersea fiber optic transmission facilities, it
does not control the construction of such facilities and must seek access to
such facilities through partial ownership positions. If ownership positions are
not available, the Company must seek access to such facilities through lease
arrangements on negotiated terms that may vary with industry and market
conditions. There can be no assurance that the Company will be able to continue
to obtain sufficient transmission facilities or access to undersea fiber optic
cable on economically viable terms. The failure of the Company to obtain
telecommunications facilities that are sufficient to support its network traffic
in a manner that ensures the reliability and quality of its telecommunications
services may have a material adverse effect on its business, financial condition
or results of operations.
 
RISKS OF INTERNATIONAL TELECOMMUNICATIONS BUSINESS
 
    The Company has to date generated a substantial majority of its revenues by
providing international telecommunications services to its customers on a
wholesale basis. The international nature of the Company's operations involves
certain risks, such as changes in U.S. and foreign government regulations and
telecommunications standards, dependence on foreign partners, tariffs, taxes and
other trade barriers, the potential for nationalization and economic downturns
and political instability in foreign countries. In addition, the Company's
business could be adversely affected by a reversal in the current trend toward
deregulation of telecommunications carriers. The Company will be increasingly
subject to these risks to the extent that the Company proceeds with the planned
expansion of its international operations.
 
                                       9
<PAGE>
    RISK OF DEPENDENCE ON FOREIGN PARTNERS.  The Company will increasingly rely
on foreign partners to terminate its traffic in foreign countries and to assist
in installing transmission facilities and network switches, complying with local
regulations, obtaining required licenses, and assisting with customer and vendor
relationships. The Company may have limited recourse if its foreign partners do
not perform under their contractual arrangements with the Company. The Company's
arrangements with foreign partners may expose the Company to significant legal,
regulatory or economic risks.
 
    RISKS ASSOCIATED WITH FOREIGN GOVERNMENT CONTROL AND HIGHLY REGULATED
MARKETS.  Governments of many countries exercise substantial influence over
various aspects of the telecommunications market. In some cases, the government
owns or controls companies that are or may become competitors of the Company or
companies (such as national telephone companies) upon which the Company and its
foreign partners may depend for required interconnections to local telephone
networks and other services. Accordingly, government actions in the future could
have a material adverse effect on the Company's operations. In highly regulated
countries in which the Company is not dealing directly with the dominant local
exchange carrier, the dominant carrier may have the ability to terminate service
to the Company or its foreign partner and, if this occurs, the Company may have
limited or no recourse. In countries where competition is not yet fully
established and the Company is dealing with an alternative operator, foreign
laws may prohibit or impede new operators from offering services in these
markets.
 
    RISKS ASSOCIATED WITH FOREIGN CURRENCY FLUCTUATIONS.  The Company's revenues
and cost of long distance services are sensitive to foreign currency
fluctuations. The Company expects that an increasing portion of the Company's
net revenue and expenses will be denominated in currencies other than U.S.
dollars, and changes in exchange rates may have a significant effect on the
Company's results of operations. Although the Company utilizes hedging
instruments to reduce the risk of foreign currency fluctuations, the Company
will not be fully protected from these risks and the instruments themselves
involve a degree of risk. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
 
    FOREIGN CORRUPT PRACTICES ACT.  The Company is also subject to the Foreign
Corrupt Practices Act ("FCPA"), which generally prohibits U.S. companies and
their intermediaries from bribing foreign officials for the purpose of obtaining
or keeping business. The Company may be exposed to liability under the FCPA as a
result of past or future actions taken without the Company's knowledge by
agents, strategic partners and other intermediaries. Such liability could have a
material adverse effect on the Company's business, operating results and
financial condition.
 
POTENTIAL ADVERSE EFFECTS OF GOVERNMENT REGULATION
 
    The Company's business is subject to various U.S. and foreign laws,
regulations, agency actions and court decisions. The Company's U.S.
international telecommunications service offerings are subject to regulation by
the Federal Communications Commission (the "FCC"). The FCC requires
international carriers to obtain certificates of public convenience and
necessity prior to acquiring international facilities by purchase or lease, or
providing international service to the public. Prior FCC approval is also
required to transfer control of a certificated carrier. The Company must file
reports and contracts with the FCC and must pay regulatory fees, which are
subject to change. The Company is also subject to the FCC policies and rules
discussed below. The FCC could determine, by its own actions or in response to a
third party's filing, that certain of the Company's services, termination
arrangements, agreements with foreign carriers, transit or refile arrangements
or reports did not comply with FCC policies and rules. If this occurred, the FCC
could order the Company to terminate noncompliant arrangements, fine the Company
or revoke the Company's authorizations. Any of these actions could have a
material adverse effect on the Company's business, operating results and
financial condition.
 
    FCC INTERNATIONAL PRIVATE LINE RESALE POLICY.  The FCC's international
private line ("IPL") resale policy limits the conditions under which a carrier
may connect IPLs to the public switched telephone
 
                                       10
<PAGE>
network ("PSTN") at one or both ends to provide switched services, commonly
known as International Simple Resale ("ISR"). A carrier generally may only offer
ISR services to a foreign country if the FCC has found (a) the country is a
member of the World Trade Organization ("WTO") and at least 50% of the U.S.
billed and settled traffic to that country is settled at or below the FCC's
benchmark settlement rate or (b) the country is not a WTO member, but it offers
U.S. carriers equivalent opportunities to engage in ISR and at least 50% of the
U.S. billed and settled traffic is settled at or below the applicable benchmark.
The Company's FCC authority currently permits it to provide ISR service to
Canada, the U.K., Sweden, New Zealand, Australia and the Netherlands. The FCC is
currently reviewing U.S. carrier applications to provide ISR to Belgium, Chile,
Denmark, Finland, France, Germany, Hong Kong, Norway and Luxembourg, among other
routes. Upon grant of any such ISR application to a given country, the FCC's
rules also would permit the Company to provide ISR service to that country.
Certain of the Company's termination arrangements with foreign operators may be
inconsistent with the FCC's IPL resale policy and the Company's existing ISR
authorization.
 
    FCC INTERNATIONAL SETTLEMENTS POLICY.  The FCC's International Settlement
Policy ("ISP") limits the arrangements which U.S. international carriers may
enter into with foreign carriers for exchanging public switched
telecommunications traffic, which the FCC terms International Message Telephone
Service ("IMTS"). This policy does not apply to ISR services. The ISP requires
that U.S. carriers receive an equal share of the accounting rate and receive
inbound traffic in proportion to the volume of U.S. outbound traffic which they
generate. The ISP also prohibits a U.S. carrier and a foreign carrier which
possesses sufficient market power on the foreign end of the route to affect
competition adversely in the U.S. market from entering into exclusive
arrangement involving services, facilities or functions on the foreign end of a
U.S. international route which are necessary for providing basic
telecommunications and which are not offered to similarly situated U.S.
carriers. It is possible that the FCC could find that certain of the Company's
arrangements with foreign operators are inconsistent with the ISP.
 
    FCC POLICIES ON TRANSIT AND REFILE.  The Company uses both transit and
refile arrangements to terminate its international traffic. The FCC routinely
approves transit arrangements by U.S. international carriers. The FCC's rules
also expressly permit carriers to use ISR facilities to route traffic via a
third country for refile through the PSTN. The extent to which U.S. carriers may
enter into refile arrangements, consistent with the ISP, is currently under
review by the FCC. Certain of the Company's transit or refile arrangements may
violate the ISP or other FCC policies.
 
    RECENT AND POTENTIAL FCC ACTIONS.  Regulatory action that may be taken in
the future by the FCC may intensify the competition which the Company faces,
impose additional operating costs upon the Company, disrupt certain of the
Company's transmission arrangements or otherwise require the Company to modify
its operations. Future FCC action may also provide the Company additional
competitive flexibility by, for example, eliminating or substantially reducing
the tariff requirements applicable to the Company's interstate and international
telecommunications services. The FCC is encouraging new market entrants by
implementing the WTO Basic Telecommunications Agreement (the "WTO Agreement")
and through other actions. The FCC may approve pending mergers which could
produce more effective competitors in the Company's markets. The FCC may
increase regulatory fees charged to the Company and its competitors by
eliminating the exemption for carriers which provide only international services
or through other actions, which could raise the Company's costs of service
without assurance that the Company and its competitors could pass fee increases
through to their customers. See "Business--Government Regulation."
 
    STATE.  The intrastate long distance telecommunications operations of STAR
and its subsidiaries are subject to various state laws and regulations,
including prior certification, notification, registration and/or
 
                                       11
<PAGE>
tariff requirements. The vast majority of states require that STAR and its
subsidiaries apply for certification to provide intrastate telecommunications
services. Certificates of authority can generally be conditioned, modified or
revoked by state regulatory authorities for failure to comply with state laws
and regulations. Fines and other penalties, including revocation of a
certificate of authority, may be imposed.
 
    In 1997, prior to the Company's acquisition of LDS, LDS settled disputes
with the California Public Utilities Commission (the "California PUC") and with
the District Attorney of Monterey, California regarding LDS' alleged
unauthorized switching of long distance customers (the "Settlements"). As part
of the Settlements, LDS was subject to fines and restrictions on its business
operations in California. In addition, the FCC has received numerous informal
complaints against LDS regarding the alleged unauthorized switching of long
distance customers, which complaints currently remain under review.
 
    Following the Company's acquisition of LDS and in order to comply with the
Settlements, STAR has imposed strict restrictions on certain former LDS
employees, restricting these employees with respect to California intrastate
telecommunications operations. Additionally, the Company has taken a number of
steps to reduce the risk of a repeat occurrence regarding the alleged
unauthorized switching of commercial customers in California. If the Company
inadvertently fails to comply with such guidelines or if such guidelines are
determined to be inadequate to comply with the Settlements, the Company may be
subject to penalties or revocation of its certificate of authority. See
"Business--Government Regulation--Actions Against LDS."
 
    FOREIGN REGULATIONS.  The Company is also subject to regulation in foreign
countries, such as the U.K. and Germany, in connection with certain of its
business activities. For example, the Company's use of transit, ISR or other
routing arrangements may be affected by laws or regulations in either the
transited or terminating foreign jurisdiction. Foreign countries, either
independently or jointly as members of the International Telecommunications
Union ("ITU"), or other supra-national organizations such as the European Union
or the WTO, may have adopted or may adopt laws or regulatory requirements
regarding such services for which compliance would be difficult or expensive,
that could force the Company to choose less cost-effective routing alternatives
and that could adversely affect the Company's business, operating results and
financial condition.
 
    To the extent that it seeks to provide telecommunications services in other
non-U.S. markets, the Company is subject to the developing laws and regulations
governing the competitive provision of telecommunications services in those
markets. The Company currently plans to provide a limited range of services in
Mexico, Belgium and France, as permitted by regulatory conditions in those
markets, and to expand its operations as these markets implement scheduled
liberalization to permit competition in the full range of telecommunications
services in the next several years. The nature, extent and timing of the
opportunity for the Company to compete in these markets will be determined, in
part, by the actions taken by the governments in these countries to implement
competition and the response of incumbent carriers to these efforts. There can
be no assurance that the regulatory regime in these countries will provide the
Company with practical opportunities to compete in the near future, or at all,
or that the Company will be able to take advantage of any such liberalization in
a timely manner. See "Business--Government Regulation."
 
    REGULATION OF CUSTOMERS.  The Company's customers are also subject to
actions taken by domestic or foreign regulatory authorities that may affect the
ability of customers to deliver traffic to the Company. Regulatory sanctions
have been imposed on certain of the Company's customers in the past. While such
sanctions have not adversely impacted the volume of traffic received by the
Company from such customers to date, future regulatory actions could materially
adversely affect the volume of traffic received from a major customer, which
could have a material adverse effect on the Company's business, financial
condition and results of operations.
 
                                       12
<PAGE>
RISKS OF NETWORK FAILURE
 
    Any system or network failure that causes interruptions in the Company's
operations could have a material adverse effect on its business, financial
condition or results of operations. The Company's operations are dependent on
its ability to successfully expand its network and integrate new and emerging
technologies and equipment into its network, which are likely to increase the
risk of system failure and to cause strain upon the network. The Company's
operations also are dependent on the Company's protection of its hardware and
other equipment from damage from natural disasters such as fires, floods,
hurricanes and earthquakes, other catastrophic events such as civil unrest,
terrorism and war and other sources of power loss and telecommunications
failures. Although the Company has taken a number of steps to prevent its
network from being affected by natural disasters, fire and the like, such as
building redundant systems for power supply to the switching equipment, there
can be no assurance that any such systems will prevent the Company's switches
from becoming disabled in the event of an earthquake, power outage or otherwise.
The failure of the Company's network, or a significant decrease in telephone
traffic resulting from effects of a natural or man-made disaster, could have a
material adverse effect on the Company's relationship with its customers and the
Company's business, operating results and financial condition. See
"Business--Network."
 
DEPENDENCE ON KEY PERSONNEL
 
    The Company's success depends to a significant degree upon the efforts of
senior management personnel and a group of employees with longstanding industry
relationships and technical knowledge of the Company's operations, in
particular, Christopher E. Edgecomb, the Company's Chief Executive Officer. The
Company maintains and is the beneficiary under a key person life insurance
policy in the amount of $10.0 million with respect to Mr. Edgecomb. The Company
believes that its future success will depend in large part upon its continuing
ability to attract and retain highly skilled personnel. Competition for
qualified, high-level telecommunications personnel is intense and there can be
no assurance that the Company will be successful in attracting and retaining
such personnel. The loss of the services of one or more of the Company's key
individuals, or the failure to attract and retain other key personnel, could
materially adversely affect the Company's business, operating results and
financial condition. See "Management."
 
SIGNIFICANT COMPETITION
 
    The international telecommunications industry is intensely competitive and
subject to rapid change. The Company's competitors in the international
wholesale switched long distance market include large, facilities-based
multinational corporations and smaller facilities-based providers in the U.S.
and overseas that have emerged as a result of deregulation, switch-based
resellers of international long distance services and international joint
ventures and alliances among such companies. The Company also competes abroad
with a number of dominant telecommunications operators that previously held
various monopolies established by law over the telecommunications traffic in
their countries. International wholesale switched service providers compete on
the basis of price, customer service, transmission quality, breadth of service
offerings and value-added services. Additionally, the telecommunications
industry is in a period of rapid technological evolution, marked by the
introduction of competitive product and service offerings, such as the
utilization of the Internet for international voice and data communications. The
Company is unable to predict which technological development will challenge its
competitive position or the amount of expenditures will be required to respond
to a rapidly changing technological environment. Further, the number of the
Company's competitors is likely to increase as a result of the competitive
opportunities created by a new Basic Telecommunications Agreement concluded by
members of the WTO in February 1997. Under the terms of the WTO Agreement,
starting on January 1, 1998, the United States and over 65 countries have
committed to open their telecommunications markets to competition, foreign
ownership and adopt measures to protect against anticompetitive behavior. As a
result, the Company believes that competition will continue to increase, placing
downward pressure on prices. Such pressure could adversely affect the
 
                                       13
<PAGE>
Company's gross margins if the Company is not able to reduce its costs
commensurate with such price reductions.
 
    COMPETITION FROM DOMESTIC AND INTERNATIONAL COMPANIES.  A majority of the
U.S.-based international telecommunications services revenue is currently
generated by AT&T Corp. ("AT&T"), MCI Communications Corp. ("MCI") and Sprint
Corporation ("Sprint"). The Company also competes with WorldCom, Inc.
("WorldCom"), Pacific Gateway Exchange, Inc. and other U.S.-based and foreign
long distance providers, including the Regional Bell Operating Companies
("RBOCs"), which presently have FCC authority to resell and terminate
international telecommunication services. Many of these competitors have
considerably greater financial and other resources and more extensive domestic
and international communications networks than the Company. The Company's
business would be materially adversely affected to the extent that a significant
number of such customers limit or cease doing business with the Company for
competitive or other reasons. Consolidation in the telecommunications industry
could not only create even larger competitors with greater financial and other
resources, but could also adversely affect the Company by reducing the number of
potential customers for the Company's services.
 
    EXPANSION INTO COMMERCIAL MARKET.  With the acquisition of LDS, STAR began
providing long distance service to the commercial market, a market that is
subject to intense competition from a number of well capitalized companies. The
commercial market is also characterized by the lack of customer loyalty, with
commercial customers regularly changing service providers. There can be no
assurance that STAR will be able to compete successfully in the commercial
market. See "Business--Strategy--Expansion into Commercial Market."
 
CUSTOMER CONCENTRATION
 
    While the list of the Company's most significant customers varies from
quarter to quarter, the Company's five largest customers accounted for
approximately 30% of its revenues in 1997. The Company could lose a significant
customer for many reasons, including the entrance into the market of significant
new competitors with lower rates than the Company, downward pressure on the
overall costs of transmitting international calls, transmission quality
problems, changes in U.S. or foreign regulations or unexpected increases in the
Company's cost structure as a result of expenses related to installing a global
network or otherwise.
 
NEED FOR ADDITIONAL CAPITAL TO FINANCE GROWTH AND CAPITAL REQUIREMENTS
 
    The Company believes that it must continue to enhance and expand its network
and build out its telecommunications network infrastructure in order to maintain
its competitive position and continue to meet the increasing demands for service
quality, capacity and competitive pricing. The Company's ability to grow
depends, in part, on its ability to expand its operations through the ownership
and leasing of network capacity, which requires significant capital
expenditures, that are often incurred prior to the Company's receipt of the
related revenue.
 
    The Company believes that, based upon its present business plan, the
proceeds from the Offering, together with the Company's existing cash resources
and expected cash flow from operating activities, will be sufficient to meet its
currently anticipated working capital and capital expenditure requirements for
at least twelve months. If the Company's growth exceeds current expectations, if
the Company obtains one or more attractive opportunities to purchase the
business or assets of another company, or if the Company's cash flow from
operations after the end of such period is insufficient to meet its working
capital and capital expenditure requirements, the Company will need to raise
additional capital from equity or debt sources. There can be no assurance that
the Company will be able to raise such capital on favorable terms or at all. If
the Company is unable to obtain such additional capital, the Company may be
required to reduce the scope of its anticipated expansion, which could have a
material adverse effect on the Company's business, financial condition or
results of operations.

<PAGE>
VOLATILITY OF STOCK PRICE
 
    The market price of the shares of Common Stock has risen since the Company's
initial public offering in June 1997 and is trading at a high multiple of the
Company's earnings. The market price for such shares has been highly volatile
and may be significantly affected by factors such as actual or anticipated
fluctuations in the Company's operating results, the announcement of potential
acquisitions by the Company, changes in federal and international regulations,
activities of the largest domestic providers, industry consolidation and
mergers, conditions and trends in the international telecommunications market,
adoption of new accounting standards affecting the telecommunications industry,
changes in recommendations and estimates by securities analysts, general market
conditions and other factors. In addition, the stock market has from time to
time experienced significant price and volume fluctuations that have
particularly affected the market prices for the shares of emerging growth
companies like the Company. These broad market fluctuations may adversely affect
the market price of the Company's Common Stock.
 
CONTROL OF COMPANY BY NAMED OFFICERS AND DIRECTORS
 
    Upon the consummation of this offering, the Company's Named Officers (as
defined below) and directors in the aggregate will beneficially own
approximately 37.6% of the outstanding shares of Common Stock and the Company's
Chief Executive Officer will beneficially own approximately 31.9% of the
outstanding shares. These stockholders will be able to exercise control over all
matters requiring stockholder approval, including the election of directors and
approval of significant corporate transactions. Such concentration of ownership
may have the effect of delaying or preventing a change in control of the
Company. See "Principal Stockholders."
 
EFFECT OF CERTAIN CHARTER PROVISIONS; ANTI-TAKEOVER EFFECTS OF CERTIFICATE OF
  INCORPORATION, BYLAWS AND
 
DELAWARE LAW
 
    The Company's Board of Directors has the authority to issue up to 5,000,000
shares of Preferred Stock and to determine the price, rights, preferences,
privileges and restrictions, including voting and conversion rights of such
shares, without any further vote or action by the Company's stockholders. The
rights of the holders of Common Stock will be subject to, and may be adversely
affected by, the rights of the holders of any Preferred Stock that may be issued
in the future. The issuance of Preferred Stock, while providing flexibility in
connection with possible acquisitions and other corporate purposes, could have
the effect of making it more difficult for a third party to acquire a majority
of the outstanding voting stock of the Company. The Company has no current plans
to issue shares of Preferred Stock. The Company is also subject to the
anti-takeover provisions of Section 203 of the Delaware General Corporation Law,
which will prohibit the Company from engaging in a "business combination" with
an "interested stockholder" for a period of three years after the date of the
transaction in which the person became an interested stockholder, unless the
business combination is approved in a prescribed manner. The application of
Section 203 could have an effect of delaying or preventing a change in control
of the Company. In addition, the Company's Amended and Restated Certificate of
Incorporation provides for a classified Board of Directors such that
approximately only one-third of the members of the Board will be elected at each
annual meeting of stockholders. Classified boards may have the effect of
delaying, deferring or discouraging changes in control of the Company. Further,
certain provisions of the Company's Amended and Restated Certificate of
Incorporation and Bylaws and of Delaware law could delay or make more difficult
a merger, tender offer or proxy contest involving the Company. Additionally,
certain federal regulations require prior approval of certain transfers of
control of telecommunications companies, which could also have the effect of
delaying, deferring or preventing a change in control. See "Business--Government
Regulation," "Description of Capital Stock--Preferred Stock" and
"--Anti-takeover Effects of Provisions of the Certificate of Incorporation,
Bylaws and Delaware Law."

SHARES ELIGIBLE FOR FUTURE SALE
 
    Upon completion of this Offering, the Company will have approximately
42,804,000 shares of Common Stock outstanding (assuming no exercise of the
Underwriters' over-allotment option and no exercise of outstanding and vested
options to purchase approximately 1,334,000 shares of Common Stock outstanding
and vested as of February 28, 1998) of which 9,430,000 have been previously
registered pursuant to the Securities Act. Of the approximately 42,804,000
shares of Common Stock outstanding, the 7,000,000 shares offered hereby will be
freely transferable without restriction or further registration under the
Securities Act. Approximately 558,000 additional shares which are not currently
registered will be available for immediate unrestricted sale in the public
market on the date of this Prospectus and approximately 1,601,000 additional
shares will be available for immediate sale on the date of this Prospectus,
subject to the public information, volume limitation and notice provisions of
Rule 144 adopted under the Securities Act. Approximately 410,000 shares will be
available for sale within 45 days after the date of this prospectus, subject to
the Rule 144 public information, volume limitations and notice provisions.
Approximately 1,985,000 shares will be available for sale in the public market
45 days after the date of this Prospectus upon the expiration of certain lock-up
agreements, of which 1,875,000 shares are subject, until July 12, 1998, to the
Rule 144 public information, volume limitation and notice provisions described
below and the remaining 110,000 which remain subject to the volume and other
limitations of Rule 144. Upon the expiration of certain additional lock-up
agreements 90 days after the date of this Prospectus, (i) approximately
16,136,000 shares will be available for sale in the public market, subject to
the Rule 144 public information, volume limitation and notice provisions and
(ii) approximately 2,050,000 shares will be available for unrestricted sale in
the public market. Approximately 1,353,000 shares issued in the T-One
acquisition shall be available for sale on the date of the publication by the
Company of at least 30 days of combined operating results of STAR and T-One.
Approximately 849,000 shares issued in the LDS acquisition will be available for
sale after November 30, 1998.
 
    Certain stockholders holding approximately 7,153,000 shares of Common Stock
are entitled to registration rights with respect to their shares of Common
Stock. Sales of substantial amounts of such shares in the public market after
this offering, or the prospect of such sales, could adversely affect the market
price of the Common Stock. Such sales also might make it more difficult for the
Company to sell equity securities or equity related securities in the future at
a time and price that the Company deems appropriate. See "Description of Capital
Stock," "Shares Eligible for Future Sale" and "Underwriting."
 
YEAR 2000 COMPUTER PROGRAM FAILURE
 
    A significant percentage of the software that runs most of the computers in
the United States relies on two-digit date codes to perform computations and
decision-making functions. Commencing on January 1, 2000, these computer
programs may fail from an inability to interpret date codes properly,
misinterpreting "00" as the year 1900 rather than 2000. The Company believes
that the Company's billing, credit and call tracking systems are Year 2000
compliant and do not use programs with the two-digit date code flaw. At the same
time, a number of the computers of the Company's customers and vendors that
interface with the Company's systems may run on programs that have Year 2000
problems and may disrupt the Company's billing, credit and tracking systems.
Failure of any of the computer programs integral to the Company's key customers
and vendors could adversely affect the Company's business, operating results and
financial condition. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations."

                                USE OF PROCEEDS
 
    The net proceeds to the Company from the sale of the shares of Common Stock
to be sold by the Company in this offering (at an assumed public offering price
of $22.44) are estimated to be $149,310,000 ($164,739,600 if the Underwriters'
over-allotment option is exercised in full), after deducting underwriting
discounts and commissions and estimated offering expenses payable by the
Company. The Company will not receive any of the proceeds from the sale of
shares of Common Stock, if any, by a selling stockholder (the "Selling
Stockholder") pursuant to the Underwriters' over-allotment option.
 
    The Company intends to use approximately $80 million of the proceeds of the
offering to expand the Company's network, including the purchase of fiber optic
cable capacity, the purchase of switches and the buildout of leasehold
improvements for these facilities. The remainder of the proceeds are expected to
be used for working capital, expansion of the Company's marketing and sales
organization and general corporate purposes. Although the Company may use a
portion of the net proceeds for possible acquisition of businesses that are
complementary to those of the Company, there are no current plans in this
regard. Pending such uses, the Company plans to invest the net proceeds in
short-term, interest-bearing, investment grade securities. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
"Business--Strategy."

                                DIVIDEND POLICY
 
    The Company has never paid cash dividends on its Common Stock and has no
intention of paying cash dividends in the foreseeable future. The Company
anticipates that all future earnings, if any, generated from operations will be
retained by the Company to develop and expand its business. Any future
determination with respect to the payment of dividends will be at the discretion
of the Board of Directors and will depend upon, among other things, the
Company's operating results, financial condition and capital requirements, the
terms of then-existing indebtedness, general business conditions and such other
factors as the Board of Directors deems relevant. In addition, the Company's
existing revolving credit facility prohibits the payment of cash dividends
without the lender's consent.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
    THE FOLLOWING DISCUSSION OF THE FINANCIAL CONDITION AND RESULTS OF
OPERATIONS OF THE COMPANY SHOULD BE READ IN CONJUNCTION WITH "SELECTED
CONSOLIDATED FINANCIAL DATA" AND THE CONSOLIDATED FINANCIAL STATEMENTS AND THE
NOTES THERETO, EACH OF WHICH IS INCLUDED ELSEWHERE IN THIS PROSPECTUS. THIS
DISCUSSION CONTAINS FORWARD-LOOKING STATEMENTS, AS DEFINED IN SECTION 27A OF THE
SECURITIES ACT, THAT INVOLVE RISKS AND UNCERTAINTIES. STAR'S ACTUAL RESULTS
COULD DIFFER MATERIALLY FROM THOSE ANTICIPATED IN THE FORWARD-LOOKING STATEMENTS
AS A RESULT OF CERTAIN FACTORS, INCLUDING, BUT NOT LIMITED TO THOSE DISCUSSED IN
"RISK FACTORS" AND ELSEWHERE IN THIS PROSPECTUS. SEE "DESCRIPTION OF
FORWARD-LOOKING STATEMENTS."
 
OVERVIEW
 
    The Company is an emerging multinational carrier focused primarily on the
international long distance market. The Company offers highly reliable, low-cost
switched voice services on a wholesale basis, primarily to U.S.-based long
distance carriers. STAR provides international long distance service to
approximately 220 countries through its flexible network comprised of various
foreign termination relationships, international gateway switches, leased and
owned transmission facilities and resale arrangements with other long distance
providers.
 
    The Company installed its first international gateway switch in Los Angeles
in June 1995 and initially recognized wholesale revenues in August 1995. A
significant portion of the Company's revenues in 1994 and 1995 were generated by
the commercial operations of LDS.
 
    REVENUES.  Most of the Company's revenues are generated by the sale of
international long distance services on a wholesale basis to other, primarily
domestic, long distance providers. The Company records revenues from the sale of
long distance services at the time of customer usage. The Company's agreements
with its wholesale customers are short-term in duration and the rates charged to
customers are subject to change from time to time, generally with five days
notice to the customer.
 
    COST OF SERVICES.  The Company has pursued a strategy of attracting
customers and building calling volume and revenue by offering favorable rates
compared to other long distance providers. The Company continues to lower its
cost of services by (i) expanding the Company's owned network facilities, (ii)
continuing to utilize the Company's sophisticated information systems to route
calls over the most cost-effective routes and (iii) leveraging the Company's
traffic volumes and information systems to negotiate lower variable usage-based
costs with domestic and foreign providers of transmission capacity.
 
    Cost of services includes those costs associated with the transmission and
termination of international long distance services. Currently, a majority of
transmission capacity used by the Company is obtained on a variable, per minute
basis. As a result, some of the Company's current cost of services is variable.
The Company's contracts with its vendors provide that rates may fluctuate, with
rate change notice periods varying from five days to one year, with certain of
the Company's longer term arrangements requiring the Company to meet minimum
usage commitments in order to avoid penalties. Such variability and the short-
term nature of many of the contracts subject the Company to the possibility of
unanticipated cost increases and the loss of cost-effective routing
alternatives. Included in the Company's cost of services are accruals for rate
and minute disputes and unreconciled billing differences between the Company and
its vendors. Each quarter management reviews the cost of services accrual and
adjusts the balance for resolved items. Cost of services also includes fixed
costs associated with the leasing of network facilities.
 
    The Company intends to begin providing international long distance services
to commercial customers in certain European countries in the second half of
1998. STAR began providing long distance service to commercial markets in the
U.S. with its acquisition of LDS in November 1997. STAR believes that traffic
from commercial customers has the potential to generate higher gross margins
than wholesale traffic. STAR also expects, however, that an expansion into this
market will also increase the risk of bad debt
 
                                       21
<PAGE>
exposure and lead to higher overhead costs. Information related to wholesale and
commercial revenues and operations will be reported in future Exchange Act
filings made by STAR in accordance with Financial Accounting Standards Board
Statement No. 131.
 
    Prices in the international long distance market have declined in recent
years and, as competition continues to increase, STAR believes that prices are
likely to continue to decline. Additionally, STAR believes that the increasing
trend of deregulation of international long distance telecommunications will
result in greater competition, which could adversely affect STAR's revenue per
minute and gross margin. STAR believes, however, that the effect of such
decreases in prices will be offset by increased calling volumes and decreased
costs.
 
    OPERATING EXPENSES.  Selling, general and administrative expenses consist
primarily of personnel costs, depreciation and amortization, tradeshow and
travel expenses and commissions and consulting fees, as well as an accrual for
bad debt expense. These expenses have been increasing over the past year, which
is consistent with STAR's recent growth, accelerated expansion into Europe, and
investment in systems and facilities. The Company expects this trend to
continue, and to include, among other things, a significant increase in
depreciation and amortization. Management believes that additional selling,
general and administrative expenses will be necessary to support the expansion
of the Company's network facilities, its sales and marketing efforts and STAR's
expansion into commercial markets.
 
    FOREIGN EXCHANGE.  The Company's revenues and cost of long distance services
are sensitive to foreign currency fluctuations. The Company expects that an
increasing portion of the Company's revenues and expenses will be denominated in
currencies other than U.S. dollars, and changes in exchange rates may have a
significant effect on the Company's results of operations.
 
    FACTORS AFFECTING FUTURE OPERATING RESULTS.  The Company's quarterly
operating results are difficult to forecast with any degree of accuracy because
a number of factors subject these results to significant fluctuations. As a
result, STAR believes that period-to-period comparisons of its operating results
are not necessarily meaningful and should not be relied upon as indications of
future performance.
 
    The Company's revenues, costs and expenses have fluctuated significantly in
the past and are likely to continue to fluctuate significantly in the future as
a result of numerous factors. The Company's revenues in any given period can
vary due to factors such as call volume fluctuations, particularly in regions
with relatively high per-minute rates; the addition or loss of major customers,
whether through competition, merger, consolidation or otherwise; the loss of
economically beneficial routing options for the termination of STAR's traffic;
financial difficulties of major customers; pricing pressure resulting from
increased competition; and technical difficulties with or failures of portions
of STAR's network that impact STAR's ability to provide service to or bill its
customers. STAR's cost of services and operating expenses in any given period
can vary due to factors such as fluctuations in rates charged by carriers to
terminate STAR's traffic; increases in bad debt expense and reserves; the timing
of capital expenditures, and other costs associated with acquiring or obtaining
other rights to switching and other transmission facilities; changes in STAR's
sales incentive plans; and costs associated with changes in staffing levels of
sales, marketing, technical support and administrative personnel. In addition,
STAR's operating results can vary due to factors such as changes in routing due
to variations in the quality of vendor transmission capability; loss of
favorable routing options; the amount of, and the accounting policy for, return
traffic under operating agreements; actions by domestic or foreign regulatory
entities; the level, timing and pace of STAR's expansion in international and
commercial markets; and general domestic and international economic and
political conditions. Further, a substantial portion of transmission capacity
used by the Company is obtained on a variable, per minute and short term basis,
subjecting the Company to the possibility of unanticipated price increases and
service cancellations. Since STAR does not generally have long term arrangements
for the purchase or resale of long distance services, and since rates fluctuate
significantly over short periods of time, STAR's gross margins are subject to
significant fluctuations over short periods
 
                                       22
<PAGE>
of time. The Company's gross margins also may be negatively impacted in the
longer term by competitive pricing pressures.
 
RECENT ACQUISITIONS AND DEVELOPMENTS
 
    The Company has recently acquired or entered into agreements to acquire the
following companies and has taken the following actions:
 
    - L.D. SERVICES, INC. On November 30, 1997, the Company acquired LDS,
      certain non-operating entities and majority ownership in another entity
      for approximately 849,000 shares of Common Stock in a transaction
      accounted for as a pooling of interests. The Company's audited financial
      statements have been restated to include LDS' historical performance for
      all relevant periods. The commercial business of LDS has historically had
      higher gross margins and higher selling, general and administrative
      expenses and operating costs than the Company's wholesale operations. As
      the Company integrates and expands the commercial accounts of LDS, such
      increase in operations may affect the Company's future operating margins.
      In 1997, LDS settled disputes with the California PUC and with the
      District Attorney of Monterey, California. The resulting payments and
      restrictions on LDS' activities adversely affected its 1997 operating
      results. See "Business--Government Regulation--Actions Against LDS."
 
    - T-ONE CORP. On March 10, 1998, the Company acquired T-One for 1,353,000
      shares of Common Stock in a transaction accounted for as a pooling of
      interests. Consistent with applicable accounting standards, as of the date
      of this Prospectus, the Company's audited financial statements have not
      been restated to include T-One's historical performance. For the fiscal
      year ended December 31, 1997, T-One had revenues of $30.4 million, gross
      profit of $1.8 million, selling, general and administrative expenses of
      $1.5 million and net income of $0.2 million. See Note 14 of Notes to
      Consolidated Financial Statements.
 
    - UNITED DIGITAL NETWORK, INC. On November 19, 1997, the Company entered
      into an agreement to acquire UDN in a transaction to be accounted for as a
      pooling of interests. The acquisition of UDN is subject to approval by
      UDN's stockholders and to various regulatory approvals. Assuming the
      receipt of all necessary approvals, management expects to consummate the
      UDN acquisition in the second quarter of 1998 for approximately 800,000
      shares of Common Stock. In connection with the UDN acquisition, STAR has
      loaned an aggregate of $4.5 million to UDN. The Company's financial
      statements have not been restated to reflect the acquisition of UDN. Based
      solely on information provided by UDN to STAR, which has not been
      independently verified by STAR, for the nine month period ended January
      31, 1998, UDN had revenues of $23.9 million and a net loss of $6.5
      million. STAR believes that, because UDN operates in the commercial
      market, its higher gross margins and operating costs will have an impact
      on the Company's margins upon consummation of the merger and on a
      going-forward basis once STAR's operating results are restated to include
      UDN's historical performance. UDN's Common Stock trades on the Vancouver
      Stock Exchange under the symbol UDN.
 
    - STOCK SPLIT. On March 31, 1998, the Company will give effect to the Stock
      Split with payment to the holders of the shares of Common Stock
      outstanding on February 20, 1998 a stock dividend equal to 1.05 shares of
      Common Stock for each such outstanding share.

</TABLE>
 
YEARS ENDED DECEMBER 31, 1997 AND 1996
 
    REVENUES.  Revenues increased 58.1% to $376.2 million in 1997 from $238.0
million in 1996. Wholesale revenues increased to $348.7 million from $208.1
million, with minutes of use increasing to 863.3 million minutes in 1997, as
compared to 479.7 million minutes of use in the prior year. This increase
reflects an increase in the number of wholesale customers from 84 in 1996 to 105
at the end of 1997, as well as an increase in usage by existing customers. The
average rate per minute of usage for wholesale customers declined from $0.43
cents per minute in 1996 to $0.40 cents per minute in 1997, reflecting the
change in country mix to include a larger proportion of lower rate per minute
countries as well as lower prices on competitive routes. Taking into account the
acquisition of T-One, on a pro forma basis, revenues in 1997 would have been
$406.6 million, an increase of 56.1% from $260.4 million in 1996.
 
    Commercial revenues decreased to $27.5 million in 1997 from $29.9 million in
1996 reflecting the termination of the LDS customer base in California due to
the 1997 settlement entered into by LDS with each of the California PUC and the
District Attorney of Monterey, California. See "Business--Governmental
Regulation--Actions Against LDS."
 
    GROSS PROFIT.  Gross profit increased 57.3% to $51.0 million in 1997 from
$32.4 million in 1996. Wholesale gross profit increased to $39.8 million in 1997
from $19.7 million for 1996 and wholesale gross margin increased to 11.4% from
9.4%, respectively. Wholesale gross profit expanded during 1997 as traffic was
increasingly routed over the Company's proprietary international network.
Commercial gross profit decreased 11.8% to $11.2 million in 1997 from $12.7
million in 1996 and commercial gross margin declined to 40.7% from 42.6% over
such periods, reflecting declining prices in the competitive long distance
market. As STAR migrates the LDS commercial customer base onto the Company's
network, LDS' cost of commercial long distance services is expected to decline.
Taking into account the acquisition of T-One, on a pro forma basis, gross profit
in 1997 would have been $52.8 million, an increase of 56.4% over gross profit of
$33.7 million in 1996.
 
    SELLING, GENERAL AND ADMINISTRATIVE.  In 1997, selling, general and
administrative expenses increased 3.1% to $35.4 million, from $34.3 million in
1996. Wholesale selling, general and administrative expenses increased to $26.0
million in 1997 from $24.1 million in 1996, but decreased as a percentage of
wholesale revenues to 7.5% from 11.6% over the comparable periods. Total
expenses increased year to year in
 
                                       24
<PAGE>
absolute dollars as STAR expanded its proprietary international network and
employee base. Included in the 1996 selling, general and administrative expense
was $11.6 million in reserves and write-offs against deposits and accounts
receivable related to bad debts from two customers. Commercial selling, general
and administrative expenses decreased to $9.4 million in 1997 from $10.2 million
in 1996 and remained flat as a percentage of commercial revenues at
approximately 34.1%. The Company expects selling, general and administrative
expenses to expand in absolute dollars and as a percentage of revenues in fiscal
year 1998, as the Company expands its network and employee base and in
connection with the Company's entry into the commercial market.
 
    DEPRECIATION.  Depreciation increased to $4.2 million for 1997 from $1.2
million for 1996, and increased as a percentage of revenues to 1.1% from 0.5% in
the prior period. Depreciation increased as a result of STAR's continuing
expansion of its proprietary international network which includes purchases of
switches, submarine cable and leasehold improvements associated with switch
sites. STAR expects depreciation expense to increase as the Company continues to
expand its global telecommunications network.
 
    OTHER INCOME (EXPENSE).  Other expense, net, increased to $2.6 million in
1997 from $552,000 in 1996. This increase is primarily due to interest expense
of $1.6 million incurred under various capital leases and bank lines of credit
and a legal settlement and associated expenses of $1.7 million. The legal
settlement relates to the dispute settled by LDS with the California PUC and the
District Attorney of Monterey County. See "Business--Governmental
Regulation--Action Against LDS." Interest income earned on short-term
investments increased to $492,000 in 1997 from $110,000 in 1996 due to interest
earned on the proceeds of the Company's June 1997 initial public offering.
 
    PROVISION FOR INCOME TAXES.  The provision for income taxes increased to
$2.9 million in 1997 from $592,000 in 1996, primarily due to the increase in
profitability of the Company.
 
YEARS ENDED DECEMBER 31, 1996 AND 1995
 
    REVENUES.  Revenues increased 414.2% to $238.0 million in 1996 from $46.3
million 1995. Wholesale revenues increased to $208.1 million in 1996 from $16.1
million in 1995, with minutes of use increasing to 479.7 million in 1996, as
compared to 38.1 million minutes of use in the prior year. The increase in
wholesale revenue resulted from STAR's commencement of operations as an
international long distance carrier, an increase in the number of customers as
compared to the prior year and an increase in minutes of wholesale traffic from
new and existing customers. The increase in traffic is also attributable to an
increase in the number of routes with favorable rates that STAR was able to
offer to customers. Commercial revenues decreased to $29.9 million in 1996 from
$30.2 million in 1995 due to a decrease in the rate per minute charged, which
was partially offset by an increase in the number of minutes sold. Taking into
account the acquisition of T-One, on a pro forma basis revenues would have been
$260.4 million in 1996, an increase of 341.9% from $58.9 million in 1995.
 
    GROSS PROFIT.  Gross profit increased 125.3% to $32.4 million for 1996 from
$14.4 million in 1995. Wholesale gross profit increased to $19.7 million in 1996
from $1.8 million for 1995. Wholesale gross margin decreased to 9.4% in 1996
from 11.0% in 1995, reflecting the change from STAR's prior consulting business
to operating as an international long distance carrier. Gross profit was
positively impacted during 1996 by the negotiation of lower rates on routes with
significant traffic, and negatively impacted by increases in traffic on routes
with lower margins. Commercial gross profit increased to $12.7 million in 1996
from $12.6 million in 1995 with gross margin increasing to 42.6% from 41.8%,
respectively. The gross profit from commercial services expanded as costs
associated with the local exchange carriers declined. Taking into account the
acquisition of T-One, on a pro forma basis, gross profit in 1996 would have been
$33.7 million, an increase of 130.0% from $14.7 million in 1995.
 
    SELLING, GENERAL AND ADMINISTRATIVE.  Selling, general and administrative
expenses increased 240.4% to $34.3 million in 1996 from $10.1 million in 1995.
Wholesale selling, general and administrative expenses
 
                                       25
<PAGE>
increased to $24.1 million in 1996 from $2.1 million in 1995, and decreased as a
percentage of revenues to 11.6% from 12.8% in the prior period. Selling, general
and administrative expenses increased between periods as STAR increased its
employee base and incurred payroll, employee benefits, commission and related
expenses. STAR also established a reserve for doubtful accounts to reflect its
significantly higher revenue levels and invested in sales and marketing
activities, including tradeshows and travel. Hi-Rim and CCI, two of STAR's major
customers in 1996, informed STAR that they were experiencing financial
difficulties and would be unable to pay in full outstanding accounts receivable.
As a result, the full amount of the approximately $10.8 million owed to STAR by
Hi-Rim and CCI as of December 31, 1996 which was not subsequently collected or
for which no offsetting value was received, was written off or reserved in 1996.
In addition, STAR wrote-off $820,000 of intangible assets relating to CCI.
Commercial selling, general and administrative expenses increased to $10.2
million in 1996 from $8.0 million in 1995 reflecting higher operating costs.
 
    DEPRECIATION.  Depreciation increased to $1.2 million for 1996 from $186,000
for 1995, an increase as a percentage of revenues to 0.5% from 0.4% in the prior
period. Depreciation increased as a result of STAR's purchase of switches and of
the operating equipment and leasehold improvements associated with its Los
Angeles and New York switching facilities. Depreciation expense will increase as
STAR expands its ownership of switching and transmission facilities through
purchase or use of capital leases.
 
    OTHER INCOME (EXPENSE).  Other expense, net, increased to $552,000 in 1996
from $75,000 in 1995. This increase is primarily due to a $100,000 legal
settlement in the second quarter of 1996 as well as $601,000 in interest expense
incurred under various bank and stockholder lines of credit. This increase was
offset by $110,000 in interest income on short-term investments and cash
equivalents primarily from funds raised in private placements of equity
securities during the first three quarters of 1996.
 
    PROVISION FOR INCOME TAXES.  Through December 31, 1995, STAR had elected to
be taxed as an S-Corporation for both federal and state income tax purposes and
thus was only subject to 1.5% tax on taxable income for state purposes. LDS was
an S-Corporation through the date of the merger on November 30, 1997. The pro
forma provision for income taxes, assumes that both STAR and LDS were
C-Corporations for all periods presented. During 1996, the historical provision
for income taxes increased to $592,000 as a result of the reserve of $2.9
million of the net deferred tax asset.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    As of December 31, 1997, STAR had cash and cash equivalents of approximately
$1.5 million, short-term investments of $18.6 million and a working capital
surplus of $15.8 million. In June 1997, the Company completed an initial public
offering of 9.4 million shares of Common Stock of which approximately 8.1
million shares were sold by the Company and approximately 1.3 million shares
were sold by certain selling stockholders. The net proceeds to the Company
(after deducting underwriting discounts and offering expenses) from the sale of
such shares of Common Stock were approximately $30.9 million. As of December 31,
1997, the Company had used the proceeds from the offering to repay indebtedness
of $14.2 million, to purchase switching and transmission related equipment and
to finance the Company's operations in the U.K.
 
    As of December 31, 1997, STAR had no funds outstanding on its $25 million
revolving line of credit, which bears interest at a rate of the bank's cost of
funds plus 175 basis points and expires on July 1, 1999. However, the line of
credit is reduced by outstanding letters of credit in the amount of $4.9
million.
 
    STAR generated net cash from operating activities of $10.1 million in 1997,
primarily from net income plus depreciation and amortization, while using $3.4
million in 1996. The Company's investing activities used cash of approximately
$29.6 million during 1997 primarily resulting from capital expenditures and the
investment of the proceeds from the initial public offering in marketable
securities, while using $9.8 million in 1996. The Company's financing activities
provided cash of approximately $19.3 million during 1997
 
                                       26
<PAGE>
primarily from the sale of Common Stock and borrowings under lines of credit,
offset by repayments under various lines of credit, while providing $14.7
million in 1996.
 
    STAR had capital lease obligations of $13.6 million, and $0.8 million in
term loans, relating to its switching facilities and operating equipment. STAR
anticipates making capital expenditures of approximately $80.0 million over the
next 12 months to expand its global network. STAR believes that the proceeds
from this offering and cash generated from operations, as well as funding under
its bank line of credit, will satisfy STAR's current liquidity needs.
Nevertheless, as the Company continues to expand its network facilities and
pursues its strategy of growth through acquisition, the Company's liquidity
needs may increase, perhaps significantly, which could require the Company to
seek such additional financing or the expansion of its borrowing capacity under
current or new lines of credit. As appropriate, STAR will use capital lease
financing or raise additional debt or equity capital to finance new projects or
acquisitions. The Company had foreign currency contracts outstanding at December
31, 1997 in the notional amount of $6.3 million. See Note 2 of Notes to
Consolidated Financial Statements.
 
    YEAR 2000 COMPLIANCE.  The Company has made a concerted effort to insure
that the software components of its information and billing systems are Year
2000 compliant. As such, management believes that, after January 1, 2000, the
Company will be able to continue to accurately track and bill calls. At the same
time, it is likely that the operations of a number of the Company's customers
and vendors rely on software that is not Year 2000 compliant.

OVERVIEW
 
    STAR is an emerging multinational carrier focused primarily on the
international long distance market. The Company offers highly reliable, low-cost
switched voice services on a wholesale basis, primarily to U.S.-based long
distance carriers. STAR provides international long distance service to
approximately 220 foreign countries through a flexible network comprised of
various foreign termination relationships, international gateway switches,
leased and owned transmission facilities and resale arrangements with long
distance providers. The Company has grown its revenues rapidly by capitalizing
on the deregulation of international telecommunications markets, combining
sophisticated information systems with flexible routing and leveraging
management's industry expertise. STAR has increased its revenues from $46.3
million in 1995 to $376.2 million in 1997.
 
INDUSTRY BACKGROUND
 
    The international long distance telecommunications services industry
consists of all transmissions of voice and data that originate in one country
and terminate in another. This industry is undergoing a period of fundamental
change which has resulted in substantial growth in international
telecommunications traffic. According to industry sources, worldwide gross
revenues for providers of international telephone service were over $60 billion
in 1996 and the volume of international traffic on the public telephone network
is expected to grow at a compound annual growth rate of approximately 13% from
1996 through the year 2000.
 
    From the standpoint of U.S.-based long distance providers, the industry can
be divided into two major segments: the U.S. international market, consisting of
all international calls billed in the U.S., and the overseas market, consisting
of all international calls billed in countries other than the U.S. The U.S.
international market has experienced substantial growth in recent years, with
gross revenues from international long distance services rising from
approximately $8.5 billion in 1990 to approximately $14.9 billion in 1996,
according to FCC data.
 
    The Company believes that a number of trends in the international
telecommunications market will continue to drive growth in international
traffic, including:
 
    - continuing deregulation and privatization of telecommunications markets;
 
    - pressure to reduce international outbound long distance rates paid by end
      users driven by increased competition in newly deregulated global markets;
 
    - the dramatic increase in the availability of telephones and the number of
      access lines in service around the world;
 
    - the increasing globalization of commerce, trade and travel;
 
    - the proliferation of communications devices such as faxes, cellular
      telephones, pagers and data communications devices;
 
    - increasing demand for data transmission services, including the Internet;
      and
 
    - the increased utilization of high quality digital undersea cable and
      resulting expansion of bandwidth availability.
 
    THE DEVELOPMENT OF THE U.S. AND OVERSEAS MARKETS
 
    The 1984 deregulation of the U.S. telecommunications industry enabled the
emergence of a number of new long distance companies in the U.S. Today, there
are over 500 U.S. long distance companies, most of which are small or
medium-sized companies. In order to be successful, these small and medium-sized
 
                                       28
<PAGE>
companies need to offer their customers a full range of services, including
international long distance. However, most of these carriers do not have the
critical mass to receive volume discounts on international traffic from the
larger facilities-based carriers such as AT&T, MCI and Sprint. In addition,
these small and medium-sized companies generally have only limited capital
resources to invest in international facilities. New international carriers such
as STAR emerged to take advantage of this demand for less expensive
international bandwidth. These emerging multinational carriers acted as
aggregators of international traffic for smaller carriers, taking advantage of
larger volumes to obtain volume discounts on international routes (resale
traffic), or investing in facilities when volume on particular routes justify
such investments. Over time, as these emerging international carriers became
established and created high quality networks, they began to carry overflow
traffic from the larger long distance providers seeking lower rates on certain
routes.
 
    Deregulation and privatization have also allowed new long distance providers
to emerge in foreign markets. By eroding the traditional monopolies held by
single national providers, many of which are wholly or partially government
owned, such as Post Telegraph & Telephone operators ("PTTs"), deregulation is
providing U.S.-based providers the opportunity to negotiate more favorable
agreements with PTTs and emerging foreign providers. In addition, deregulation
in certain foreign countries is enabling U.S.-based providers to establish local
switching and transmission facilities in order to terminate their own traffic
and begin to carry international long distance traffic originated in that
country. STAR believes that growth of traffic originated in markets outside of
the U.S. will be higher than the growth in traffic originated within the U.S.
due to recent deregulation in many foreign markets, relative economic growth
rates and increasing access to telecommunications facilities in emerging
markets.
 
    INTERNATIONAL SWITCHED LONG DISTANCE SERVICES
 
    International switched long distance services are provided through switching
and transmission facilities that automatically route calls to circuits based
upon a predetermined set of routing criteria. The call typically originates on a
local exchange carrier's network and is transported to the caller's domestic
long distance carrier. The domestic long distance provider then carries the call
to an international gateway switch. An international long distance provider
picks up the call at its gateway and sends it directly or through one or more
other long distance providers to a corresponding gateway switch operated in the
country of destination. Once the traffic reaches the country of destination, it
is then routed to the party being called though that country's domestic
telephone network.
 
    International long distance providers can generally be categorized by their
ownership and use of switches and transmission facilities. The largest U.S.
carriers, such as AT&T, MCI and Sprint, primarily utilize owned transmission
facilities and generally use other long distance providers to carry their
overflow traffic. Since only very large carriers have transmission facilities
that cover the over 200 countries to which major long distance providers
generally offer service, a significantly larger group of long distance providers
own and operate their own switches but either rely solely on resale agreements
with other long distance
 
                                       29
<PAGE>
carriers to terminate their traffic or use a combination of resale agreements
and owned facilities in order to terminate their traffic as shown below:
 
                                 [LOGO]
 
    OPERATING AGREEMENTS.  Under traditional operating agreements, international
long distance traffic is exchanged under bilateral agreements between
international long distance providers in two countries. Operating agreements
provide for the termination of traffic in, and return traffic to, the
international long distance providers' respective countries at a standard
"accounting rate" with that international provider. Under a traditional
operating agreement, the international long distance provider that originates
more traffic compensates the long distance provider in the other country by
paying a net amount based on the difference between minutes sent and minutes
received and the settlement rate, which is generally one-half of the accounting
rate.
 
    Under a typical operating agreement both carriers jointly own the
transmission facilities between two countries. A carrier gains ownership rights
in a digital fiber optic cable by purchasing direct ownership in a particular
cable prior to the time the cable is placed in service, acquiring an
"Indefeasible Right of Use" ("IRU") in a previously installed cable, or by
leasing or obtaining capacity from another long distance provider that either
has direct ownership or IRUs in the cable. In situations where a long distance
provider has sufficiently high traffic volume, routing calls across directly
owned or IRU cable is generally more cost-effective on a per call basis than the
use of short-term variable capacity arrangements with other long distance
providers or leased cable. However, direct ownership and acquisition of IRUs
require a company to make an initial investment of its capital based on
anticipated usage.
 
    TRANSIT ARRANGEMENTS.  In addition to utilizing an operating agreement to
terminate traffic delivered from one country directly to another, an
international long distance provider may enter into transit arrangements
pursuant to which a long distance provider in an intermediate country carries
the traffic to a country of destination. Such transit arrangements involve
agreement among the providers in all the countries involved and are generally
used for overflow traffic or where a direct circuit is unavailable or not volume
justified.
 
    RESALE ARRANGEMENTS.  Resale arrangements typically involve the wholesale
purchase and sale of transmission and termination services between two long
distance providers on a variable, per minute basis. The resale of capacity,
which was first permitted in the U.S. market in the 1980s enabled the emergence
of new international long distance providers that rely at least in part on
capacity acquired on a wholesale basis from other long distance providers.
International long distance calls may be routed through a facilities-based
carrier with excess capacity, or through multiple long distance resellers
between the originating long
 
                                       30
<PAGE>
distance provider and the facilities-based carrier that ultimately terminates
the traffic. Resale arrangements set per minute prices for different routes,
which may be guaranteed for a set time period or subject to fluctuation
following notice. The resale market for international capacity is constantly
changing, as new long distance resellers emerge and existing providers respond
to fluctuating costs and competitive pressures. In order to be able to
effectively manage costs when utilizing resale arrangements, long distance
providers need timely access to changing market data and must quickly react to
changes in costs through pricing adjustments or routing decisions.
 
    ALTERNATIVE TERMINATION ARRANGEMENTS.  As the international
telecommunications market has become deregulated, service providers have
developed alternative arrangements to reduce their termination costs by, for
example, routing traffic via third countries to obtain lower settlement rates or
using international private line facilities to bypass the settlement rates
applicable to traffic routed over the PSTN. These arrangements include ISR,
traffic refiling and the acquisition of transmission and switching facilities in
foreign countries so as to self-correspond. Refiling of traffic takes advantage
of disparities in settlement rates between different countries. An originating
operator typically refiles traffic by sending it first to a third country that
enjoys lower settlement rates with the destination country where upon it is
forwarded or refiled to the destination country thereby resulting in a lower
overall termination cost. The difference between transit and refiling is that,
with respect to transit, the operator in the destination country typically has a
direct relationship with the originating operator and is aware of the
arrangement, while with refiling, the operator in the destination country
typically is not aware that it is terminating refiled traffic originated in
another country. With ISR, a long distance provider completely bypasses the
settlement system by connecting an IPL to the PSTN on one or both ends. While
ISR currently is only sanctioned by U.S. and other regulatory authorities on
some routes, ISR services are increasing and are expected to expand
significantly as deregulation of the international telecommunications market
continues. In addition, new market access agreements, such as the WTO Agreement,
have made it possible for many international service providers to establish
their own transmission and switching facilities in certain foreign countries,
enabling them to self-correspond and directly terminate traffic. See
"--Government Regulation."
 
    The highly competitive and rapidly changing international telecommunications
market has created a significant opportunity for carriers that can offer high
quality, low cost international long distance service. Deregulation,
privatization, the expansion of the resale market and other trends influencing
the international telecommunications market are driving decreased termination
costs, a proliferation of routing options, and increased competition. Successful
companies among both the emerging and established international long distance
companies will need to aggregate enough traffic to lower costs of both
facilities-based or resale opportunities, maintain systems which enable analysis
of multiple routing options, invest in facilities and switches and remain
flexible enough to locate and route traffic through the most advantageous
routes.
 
THE STAR APPROACH
 
    STAR is an emerging multinational carrier focused primarily on the
international long distance market. The Company offers highly reliable, low-cost
switched voice services on a wholesale basis, primarily to U.S.-based long
distance carriers. STAR provides international long distance service to
approximately 220 foreign countries through a flexible network comprised of
various foreign termination relationships, international gateway switches,
leased and owned transmission facilities and resale arrangements with long
distance providers. The Company has grown its revenues rapidly by capitalizing
on the deregulation of international telecommunications markets, combining
sophisticated information systems with flexible routing and leveraging
management's industry expertise.
 
    STAR markets its services to large global carriers seeking lower rates and
high quality overflow capacity, as well as to small and medium-sized long
distance companies that do not have the critical mass to invest in their own
international transmission facilities or to obtain volume discounts from the
larger facilities-based carriers. During the fourth quarter of 1997, the Company
provided switched international
 
                                       31
<PAGE>
long distance services to 105 customers and currently provides these services to
nine of the top forty global carriers. The Company has also recently focused on
building a customer base overseas, particularly in Europe, and has opened
offices in Dusseldorf, Frankfurt, Hamburg and Munich, Germany and London,
England. In addition, STAR has begun to market its international long distance
services directly to certain commercial customers in the U.S. and overseas.
 
STRATEGY
 
    The Company's objective is to be a leading provider of highly reliable,
low-cost switched international long distance services on a wholesale basis to
U.S. and foreign-based telecommunications companies, as well as on a retail
basis to commercial customers. Key elements of the Company's strategy include
the following:
 
    EXPAND SWITCHING AND TRANSMISSION FACILITIES.  The Company is continuing to
pursue a flexible approach to expanding and enhancing its network facilities by
investing in both switching and transmission facilities where traffic volumes
justify such investments. The Company has expanded its international gateway
switching facilities through the addition of a facility in Dallas and plans to
put into service in 1998 switches in Atlanta, Chicago, Miami and Seattle;
Dusseldorf, Frankfurt, Hamburg and Munich, Germany; Paris, France; and Tokyo,
Japan. The Company's international gateway switch in London, England went into
service in April 1997 and four switches in Germany are expected to be
operational in the second quarter of 1998. In addition, the Company is planning
to install a network of switches in selected other European and Asian cities.
 
    CAPITALIZE ON PROJECTED INTERNATIONAL LONG DISTANCE GROWTH.  The Company
believes that the international long distance market provides attractive
opportunities due to its higher revenue and profit per minute, and greater
projected growth rate as compared to the domestic long distance market. The
Company targets international markets with high volumes of traffic, relatively
high rates per minute and prospects for deregulation and privatization. The
Company believes that the ongoing trend toward deregulation and privatization
will create new opportunities for the Company in international markets. Although
the Company has focused to date primarily on providing services for U.S.-based
long distance providers, the Company also intends to expand the international
long distance services it offers to foreign-based long distance providers.
 
    LEVERAGE TRAFFIC VOLUME TO REDUCE COSTS.  The Company continues to focus on
building its volume of international long distance traffic. Higher traffic
volumes strengthen the Company's negotiating position with vendors, customers
and potential foreign partners, which allows the Company to lower its costs of
service. In addition, higher traffic volumes on particular routes allow the
Company to lower its cost of services on these routes by transitioning from
acquiring capacity on a variable cost per minute basis to fixed cost
arrangements such as longer-term capacity agreements with major carriers,
long-term leases and ownership of facilities.
 
    LEVERAGE INFORMATION SYSTEMS AND SWITCHING CAPABILITIES.  The Company
leverages its sophisticated information systems to analyze its routing
alternatives, and select the most cost-effective routing from among the Company
owned facilities, network of resale arrangements with other long distance
providers, operating agreements and alternative termination relationships. The
Company has invested significant resources in the development of software to
track specific usage information by customer and revenue and cost information on
specific routes on a daily basis. The Company's information systems are critical
components in managing its customer and vendor relationships, routing traffic to
the most cost-effective alternative, and targeting its marketing efforts.
 
    MAINTAIN HIGH QUALITY.  The Company believes that reliability, call
completion rates, voice quality, rapid set up time and a high level of customer
and technical support are key factors evaluated by U.S. and foreign-based
telecommunications companies and large corporate customers in selecting a
carrier for their
 
                                       32
<PAGE>
international traffic. The Company's state-of-the-art switching equipment is
fully compliant with international C-7 and domestic SS-7 signaling standards.
STAR strives to provide a consistently high level of customer and technical
support and has technical support personnel at its switching facilities 24 hours
per day, seven days per week to assist its customers and to continually monitor
network operations.
 
    EXPAND INTO COMMERCIAL MARKET.  The Company plans to expand into niche
commercial markets in the U.S. and in other deregulating countries where it
believes it can leverage its international network and where the customer base
has a significant international calling pattern. As an example of this strategy,
the Company is using the LDS telemarketing sales force to target small
commercial customers in ethnic markets to increase traffic to Mexico and Latin
America. Additionally, STAR intends to use UDN's network of independent sales
agents to target medium-sized commercial customers with a demand for
international calling services at competitive rates. Finally, the Company plans
to use its direct sales forces to target larger commercial customers,
concentrating at first on potential customers in Los Angeles and New York. With
respect to the offering of commercial services abroad, the Company initially
intends to focus on Germany, the U.K. and selected European cities where
competition for commercial customers is less mature.
 
    GROWTH THROUGH ACQUISITIONS.  The Company actively pursues opportunities to
enhance its business through strategic and synergistic acquisitions. These
acquisitions may focus on entering new territories, enlarging the Company's
presence in an existing territory, adding capacity or expanding into new market
segments, such as the commercial market. In addition to expanding its revenue
base, the Company plans to realize operating efficiencies by integrating
newly-acquired operations into the Company's billing, tracking and other
systems. On November 30, 1997, the Company acquired LDS, a long distance
provider focusing on small commercial customers throughout the United States,
for approximately 849,000 shares of Common Stock. On March 10, 1998, the Company
acquired T-One, an international wholesale long distance provider, for 1,353,000
shares of Common Stock. On November 19, 1997, the Company entered into an
agreement to acquire UDN, a commercial long distance provider. The acquisition
of UDN is subject to approval by UDN's stockholders and to various regulatory
approvals. Assuming the receipt of all necessary approvals, STAR expects to
consummate the UDN acquisition in the second quarter of 1998 for approximately
800,000 shares of Common Stock. Each of these transactions has been, or will be,
accounted for as a pooling of interests.
 
NETWORK
 
    The Company provides international long distance services to approximately
220 foreign countries through a flexible, switched-based network consisting of
resale arrangements with other long distance providers, various foreign
termination relationships, international gateway switches and leased and owned
transmission facilities. The Company's network employs state-of-the-art digital
switching and transmission technologies and is supported by comprehensive
monitoring and technical support personnel. The Company's switching facilities
are staffed 24 hours per day, seven days per week.
 
    TERMINATION ARRANGEMENTS
 
    The Company seeks to retain flexibility and maximize its termination
opportunities by utilizing a continuously changing mix of routing alternatives,
including resale arrangements, operating agreements and other advantageous
termination arrangements. This diversified approach is intended to enable the
Company to take advantage of the rapidly evolving international
telecommunications market in order to provide low-cost international long
distance service to its customers.
 
    STAR utilizes resale arrangements to provide it with multiple options for
routing traffic through its switches to each destination country. Traffic under
resale arrangements typically terminates pursuant to a third party's
correspondent relationships. The Company purchased capacity from 57 vendors in
1997. A substantial portion of this capacity is obtained on a variable, per
minute and short-term basis, subjecting
 
                                       33
<PAGE>
the Company to the possibility of unanticipated price increases and service
cancellations. The Company's contracts with its vendors provide that rates may
fluctuate, with rate change notice periods varying from five days to one year,
with certain of the Company's longer term arrangements requiring STAR to make
minimum usage commitments in order to achieve additional volume discounts. As a
result of deregulation and competition in the international telecommunications
market, the pricing of termination services varies by carrier depending on such
factors as call traffic and time of day. Since the Company does not typically
enter into long-term contracts with these providers, pricing can change
significantly over short periods of time. The Company's proprietary information
systems enable the Company to track the pricing variations in the international
telecommunications market on a daily basis, allowing the Company's management to
locate and reroute traffic to the most cost-effective alternatives. See "Risk
Factors--Operating Results Subject to Significant Fluctuations."
 
    The Company currently has operating agreements with carriers in a number of
countries and is in the process of negotiating additional operating agreements
for other countries. The Company has been and will continue to be selective in
entering into operating agreements. The Company also has agreements with
international providers of long distance services for termination of traffic
that the Company routes over its network to such countries. The Company
currently has such termination arrangements with several carriers in a number of
countries, and STAR is in the process of expanding its coverage of such
countries and entering into similar arrangements in additional countries. The
FCC or foreign regulatory agencies may take the view that certain of the
Company's termination arrangements do not comply with current rules and policies
applicable to international settlements, such as current ISR rules. To the
extent that the revenue generated under such arrangements becomes a significant
portion of overall revenue, the loss of such arrangements, whether as a result
of regulatory actions or otherwise, could have a material adverse effect on the
Company's business, operating results and financial condition. In addition, the
FCC could impose sanctions on the Company, including forfeitures, if certain of
the Company's arrangements are found to be inconsistent with FCC rules. See
"--Government Regulation," "Risk Factors--Risks of International
Telecommunications Business," and "--Potential Adverse Effects of Government
Regulation."
 
SWITCHES AND TRANSMISSION FACILITIES
 
    International long distance traffic to and from the U.S. is generally
transmitted through an international gateway switching facility across undersea
digital fiber optic cable or via satellite to a termination point. International
gateway switches are digital computerized routing facilities that receive calls,
route calls through transmission lines to their destination and record
information about the source, destination and duration of calls. STAR's global
network facilities include both international gateway switches and undersea
digital fiber optic cable.
 
    The Company currently operates international gateway switches in New York,
Los Angeles, Dallas and London, England. In 1998, the Company plans to put into
service international gateway switches in Atlanta, Chicago, Miami and Seattle;
Dusseldorf, Frankfurt, Hamburg and Munich, Germany; Paris, France; and Tokyo,
Japan. The Company considers any of its switches to be international gateway
switches if the Company can route international calls across such switch.
 
    STAR's switching facilities are linked to a proprietary reporting system,
which the Company believes provides it with a competitive advantage by
permitting management on a real-time basis to determine the most cost-effective
termination alternatives, monitor customer usage and manage gross margins by
route. The Company has installed multiple redundancies into its switching
facilities to decrease the risk of a network failure. For example, the Company
employs both battery and generator power back-up and has installed hardware that
automatically shifts the system to auxiliary power during a power outage, rather
than relying on manual override. STAR is in the process of adding a network
control center in its Los Angeles facility, which is expected to be completed in
1998.
 
                                       34
<PAGE>
    The Company currently holds ownership positions in a number of digital
undersea fiber optic cables, and has recently added capacity on the TPC-5
undersea fiber optic cable system and has entered into commitments to acquire
transmission capacity on three additional undersea fiber optic cable systems,
Gemini, AC-1 and China-US. The Company plans to increase its investment in
direct and IRU ownership of cable in situations where the Company enters into
operating agreements and in other situations in which it determines that such an
investment would enhance operating efficiency or reduce transmission costs.
 
    Through its acquisitions of T-One and UDN, STAR has acquired, or will
acquire, additional switching and transmission facilities. By acquiring T-One,
the Company has added a switch located in the same building as the Company's New
York international gateway switch and has added a number of operating agreements
to countries in Africa and the Middle East, among other locations. In addition,
T-One owns capacity on certain cable and satellite systems. Upon consummation of
the acquisition of UDN, the Company will acquire a switch located in the same
building as the Company's Dallas switch. The Company plans to integrate these
facilities into its existing network.
 
SALES AND MARKETING
 
    The Company markets its services on a wholesale basis to other
telecommunications companies through its experienced direct sales force and
marketing/account management team who leverage the long-term industry
relationships of the Company's senior management. The Company reaches its
customers primarily through domestic and international trade shows and through
relationships gained from years of experience in the telecommunications
industry. The Company had 20 direct sales and marketing employees and over 145
telemarketing representatives as of March 1, 1998.
 
    In the wholesale market, the Company's sales and marketing employees utilize
the extensive, customer specific usage reports and network utilization data
generated by the Company's sophisticated information systems to effectively
negotiate agreements with customers and prospective customers and to rapidly
respond to changing market conditions. The Company believes that it has been
able to compete more effectively as a result of the personalized service and
ongoing senior management-level attention that is given to each customer.
 
    In connection with the Company's expansion into the commercial market, the
Company expects to target small commercial customers through LDS' existing
telemarketing operation, deliver services to medium-sized commercial customers
through UDN's network of independent sales agents and utilize a direct sales
force to approach larger commercial accounts. Establishment of a sales force
capable of effectively expanding the Company's services into the commercial
market can be expected to require substantial efforts and management and
financial resources and may increase the Company's operating costs. See "Risk
Factors--Risks Associated with Growth of Telecommunications Network and Customer
Base."
 
INFORMATION AND BILLING SYSTEMS
 
    The Company's operations use advanced information systems including call
data collection and call data storage linked to a proprietary reporting system.
The Company also maintains redundant billing systems for rapid and accurate
customer billing. STAR's switching facilities are linked to a proprietary
reporting system, which the Company believes provides it with a competitive
advantage by permitting management on a real-time basis to determine the most
cost-effective termination alternatives, monitor customer usage and manage gross
margins by route. The Company's systems also enable it to ensure accurate and
timely billing and to reduce routing errors. As the Company's systems were
designed for the wholesale marketplace, the Company is currently in the process
of modifying its systems in anticipation of its entrance into the commercial
marketplace.
 
                                       35
<PAGE>
    The Company's proprietary reporting software compiles call, price and cost
data into a variety of reports which the Company can use to re-program its
routes on a real-time basis. The Company's reporting software can generate the
following reports as needed:
 
    - customer usage, detailing usage by country and by time period within
      country, in order to track sales and rapidly respond to any loss of
      traffic from a particular customer;
 
    - country usage, subtotaled by vendor or customer, which assists the Company
      with route and network planning;
 
    - vendor rates, through an audit report that allows management to determine
      at a glance which vendors have the lowest rates for a particular country
      in a particular time period;
 
    - vendor usage by minute, enabling the Company to verify and audit vendor
      bills;
 
    - dollarized vendor usage to calculate the monetary value of minutes passed
      to the Company's vendors, which assists with calculating operating margin
      when used in connection with the customer reports;
 
    - loss reports used to rapidly highlight routing alternatives that are
      operating at a loss as well as identifying routes experiencing substantial
      overflow; and
 
    - LATA (Domestic Call Area) reporting by originating and terminating LATA,
      allowing for accurate Local Exchange charge audits, and protecting from
      Local Exchange overcharging.
 
    STAR has built multiple redundancies into its billing and call data
collections systems. Nine call collector computers receive call information in
real-time, immediately duplicating data, sending one copy to billing, while the
other copy is used for customer service internally and for traffic analysis.
STAR maintains two independent and redundant billing systems in order to both
verify billing internally and to ensure that bills are sent out on a timely
basis. All of the call data, and resulting billing data, are continuously backed
up on tape drives and redundant storage devices, and are regularly transported
to an off-site safe location.
 
COMPETITION
 
    The international telecommunications industry is intensely competitive and
subject to rapid change. The Company's competitors in the international
wholesale switched long distance market include large, facilities-based
multinational corporations and PTTs, smaller facilities-based providers in the
U.S. and overseas that have emerged as a result of deregulation, switched-based
resellers of international long distance services and international joint
ventures and alliances among such companies. International wholesale switched
long distance providers compete on the basis of price, customer service,
transmission quality, breadth of service offerings and value-added services. The
Company also competes abroad with a number of dominant telecommunications
operators that previously held various monopolies established by law over the
telecommunications traffic in their countries. See "Risk Factors--Significant
Competition." Additionally, the telecommunications industry is in a period of
rapid technological evolution, marked by the introduction of competitive new
product and service offerings, such as the utilization of the Internet for
international voice and data communications. The Company is unable to predict
which of many possible future product and service offerings will be important to
maintain its competitive position or what expenditures will be required to
develop and provide such products and services. The Company believes that it
competes favorably on the basis of price, transmission quality and customer
service. The number of the Company's competitors is likely to increase as a
result of the new competitive opportunities created by the WTO Agreement.
Further, under the terms of the WTO Agreement, the United States and the other
68 countries participating in the Agreement have committed to open their
telecommunications markets to competition, and foreign ownership and adopt
measures to protect against anticompetitive behavior, effective starting on
January 1, 1998. As a result, the Company believes that competition will
continue to
 
                                       36
<PAGE>
increase, placing downward pressure on prices. Such pressure could adversely
affect the Company's gross margins if the Company is not able to reduce its
costs commensurate with such price reductions.
 
    COMPETITION FROM DOMESTIC AND INTERNATIONAL COMPANIES AND ALLIANCES.  A
majority of the U.S.-based international telecommunications services revenue is
currently generated by AT&T, MCI and Sprint. The Company also competes with
WorldCom, Pacific Gateway Exchange, Inc. and other U.S.-based and foreign long
distance providers, including the RBOCs, which presently have FCC authority to
resell and terminate international telecommunication services. Many of these
companies have considerably greater financial and other resources and more
extensive domestic and international communications networks than the Company.
The Company's business would be materially adversely affected to the extent that
a significant number of such customers limit or cease doing business with the
Company for competitive or other reasons. Consolidation in the
telecommunications industry could not only create even larger competitors with
greater financial and other resources, but could also adversely affect the
Company by reducing the number of potential customers for the Company's
services.
 
    EXPANSION INTO COMMERCIAL MARKET.  With the acquisition of LDS, STAR began
providing long distance service to the commercial market, a market that is
subject to intense competition from a number of well capitalized companies. The
commercial market is also characterized by the lack of customer loyalty, with
commercial customers regularly changing service providers. There can be no
assurance that STAR will be able to compete successfully in the commercial
market.
 
GOVERNMENT REGULATION
 
    The Company's U.S. interstate and international telecommunications service
offerings generally are subject to the regulatory jurisdiction of the FCC.
Certain telecommunication services offered by the Company in the U.S. may also
be subject to the jurisdiction of state regulatory authorities, commonly known
as public utility commissions ("PUCs"). The Company's telecommunications service
offerings outside the U.S. are also generally subject to regulation by national
regulatory authorities. In addition, U.S. and foreign regulatory authorities may
affect the Company's international service offerings as a result of the
termination or transit arrangements associated therewith. U.S. or foreign
regulatory authorities may take actions or adopt regulatory requirements which
could adversely affect the Company. See "Risk Factors--Potential Adverse Affect
of Government Regulation."
 
U.S. REGULATION
 
    The Company's business is subject to various U.S. and foreign laws,
regulations, agency actions and court decisions. The Company's U.S.
international telecommunications service offerings are subject to regulation by
the FCC. The FCC requires international carriers to obtain certificates of
public convenience and necessity prior to acquiring international facilities by
purchase or lease, or providing international service to the public. Prior FCC
approval is also required to transfer control of a certificated carrier. The
Company is also subject to FCC policies and rules that regulate the manner in
which international telecommunication services may be provided, including, for
instance, the circumstances under which a carrier may provide international
switched services using IPL facilities and under which it may route traffic
through third countries to or from its final destination.
 
    The Communications Act and the FCC's rules and policies also impose certain
other obligations on carriers providing international telecommunication
services. These include the obligation to file at the FCC and to maintain
tariffs containing the rates, terms and conditions applicable to their services;
to file certain reports regarding international traffic and facilities; to file
certain contracts with correspondent carriers; to disclose affiliations with
foreign carriers and significant foreign ownership interests; to pay certain
regulatory fees based, among other things, upon the carrier's revenues and
ownership of international transmission capacity.
 
                                       37
<PAGE>
    INTERNATIONAL SERVICES.  FCC rules require the Company to obtain prior FCC
authorization to acquire and operate international communication circuits in
satellites and undersea fiber optic cables; similar FCC authority is required
for the Company to resell such capacity. The Company holds both facilities-based
and resale international authorizations, including a "global" authorization that
provides broad authority to offer switched and private line international
services. The Company has filed tariffs for international services with the FCC.
 
    FCC INTERNATIONAL PRIVATE LINE RESALE POLICY.  The FCC's IPL resale policy
limits the conditions under which a carrier may connect IPLs to the PSTN at one
or both ends to provide switched services, commonly known as ISR. A carrier
generally may only offer ISR services to a foreign country if the FCC has found
(a) the country is a member of the WTO and at least 50% of the U.S. billed and
settled traffic to that country is settled at or below the benchmark settlement
rate adopted by the FCC in IB Docket No. 96-261; or (b) the country is not a WTO
member, but it offers U.S. carriers equivalent opportunities to engage in ISR
and at least 50% of the U.S. billed and settled traffic is settled at or below
the applicable benchmark. Settled traffic refers to traffic subject to an
accounting rate agreement between U.S. and foreign carriers. An accounting rate
is a per minute wholesale charge negotiated by international carriers for
terminating traffic in either direction. Each carrier is paid a settlement rate
for terminating traffic on its own network which ordinarily is one-half of the
accounting rate. The Company's FCC authority currently permit it to provide ISR
service to Canada, the U.K., Sweden, New Zealand, Australia and the Netherlands.
The FCC is currently reviewing U.S. carrier applications to provide ISR to
Belgium, Chile, Denmark, Finland, France, Germany, Hong Kong, Norway and
Luxembourg, among other routes, and upon grant of any such ISR application to a
given country, the FCC's rules also would permit the Company to provide ISR
service to that country. Certain of the Company's termination arrangements with
foreign operators involve IPL arrangements which may be inconsistent with the
foregoing FCC IPL resale policy and the Company's existing ISR authorization. If
the FCC were to determine, by its own actions or in response to the filing of a
third party that any of the Company's IPL arrangements violate its ISR policy or
the Company's ISR authorization, the FCC could order the Company to terminate
any non-conforming arrangements. In addition, the Company could be subject to a
monetary forfeiture and to other penalties, including the revocation of the
Company's FCC authorizations to operate as an international carrier. Any such
FCC action could have a material adverse effect upon the Company's business,
operating results and financial condition.
 
    FCC INTERNATIONAL SETTLEMENTS POLICY.  The FCC's ISP places limits on the
arrangements which U.S. international carriers may enter into with foreign
carriers for exchanging public switched telecommunications traffic, which the
FCC terms International Message Telephone Service. The policy does not apply to
ISR services. The ISP is primarily intended to deter dominant foreign carriers
from discriminating amongst competing U.S. carriers by, for example, favoring
the foreign carrier's U.S. affiliate. Absent FCC consent, the ISP requires that
U.S. carriers receive an equal share of the accounting rate (i.e., that
settlement rates be equivalent) and receive inbound traffic in proportion to the
volume of U.S. outbound traffic which they generate. The ISP also prohibits a
U.S. carrier from offering or accepting a "special concession" from a foreign
carrier where the foreign carrier possess sufficient market power on the foreign
end of the route to affect competition adversely in the U.S. market. A "special
concession" is defined by the FCC as an exclusive arrangement involving
services, facilities or functions on the foreign end of a U.S. international
route which are necessary for providing basic telecommunications which are not
offered to similarly situated U.S. carriers. U.S. international carriers wishing
to establish settlement arrangements for IMTS which do not comply with the ISP
must obtain a waiver of the FCC's rules or a declaratory ruling from the FCC
that the non-standard arrangement is in the public interest. FCC policy provides
that a request by a U.S. international carrier to establish a non-standard
settlement arrangement with a foreign carrier in a WTO member country is
presumptively in the public interest, and that said presumption generally may be
overcome only by a demonstration that the foreign carrier is not subject to
competition in its home market from more than one facilities-based international
carrier. Notwithstanding the FCC's ISP waiver and flexibility policies, it is
possible that the FCC could find that certain of the Company's arrangements with
 
                                       38
<PAGE>
foreign operators were or are inconsistent with the ISP and that the Company has
not requested prior FCC authority therefore. If the FCC were to determine by its
own actions or in response to the filing of a third party that the Company has
violated the ISP, the FCC could order the Company to terminate any non-
conforming arrangement. In addition, the Company could be subject to a monetary
forfeiture and to other penalties, including revocation of the Company's FCC
authorizations to operate as an international carrier. Any such FCC action could
have a material adverse effect upon the Company's business, operating results
and financial condition.
 
    The FCC's policies also require U.S. international carriers providing IMTS
to negotiate and adopt settlement rates with foreign correspondents for IMTS
which are at or below certain benchmark rates beginning January 1, 1999. U.S.
international carriers must establish IMTS settlement rates at or below the
benchmark rate with any foreign affiliate beginning April 1, 1998. The Company
expects that any IMTS operating agreement which it has or may have with a
foreign affiliate will satisfy the foregoing benchmarks requirement.
 
    The Company currently has IMTS operating agreements with certain foreign
correspondents which provide for settlement rates above the FCC's prescribed
benchmarks. The Company will negotiate in good faith to establish IMTS
settlement rates with its foreign correspondents which satisfy the FCC's
benchmarks but there can be no assurance that such negotiations will succeed.
The FCC's order adopting the foregoing settlement benchmarks and the timetable
therefor is currently being reconsidered by the FCC. Several foreign
telecommunications carriers also have petitioned the U.S. Court of Appeals to
vacate the FCC's benchmarks order because, among other things, the FCC lacks the
jurisdiction to prescribe the settlement rates which foreign carriers may
collect from U.S. carriers. However, subject to FCC reconsideration and action
by the Court of Appeals, if the Company is unable to negotiate benchmark
settlement rates with certain foreign correspondents, the FCC may intervene on
its own action or in response to a filing by a third party. The Company is
unable to predict the form which such intervention may take but it could disrupt
the Company's arrangement for transmitting traffic to certain countries require
the Company to suspend direct service to certain countries or require the
Company to make alternative termination arrangements with certain countries, all
of which could have a material adverse effect on the Company's business,
operating results and financial condition.
 
    FCC POLICIES ON TRANSIT AND REFILE.  International switched
telecommunication traffic is frequently routed indirectly via one or more third
countries to its final destination. When such arrangements are mutually agreed,
they are commonly based on a transit agreement under which settlement payments
are made to all parties. In other cases, traffic may be sent to a third country
and then forwarded or refiled for delivery to its final destination without the
knowledge or consent of the destination carrier. The Company uses both transit
and refile arrangements to terminate its international traffic. The FCC
routinely approves transit arrangements by U.S. international carriers. The
FCC's rules also expressly permit carriers to use ISR facilities to route
traffic via a third country for refile through the public switched network.
However, the extent to which U.S. carriers may enter into refile arrangements,
consistent with the ISP, is currently under review by the FCC. In 1997, the FCC
stated that above-cost accounting rates had led an increasing amount of
international traffic to migrate to least cost routes through the use of
practices such as hubbing, refile and reorigination. The FCC stated that such
practices are an economically rational response to inflated settlement rates.
Notwithstanding the FCC's past rules, policies and statements regarding the
scope of permissible transit and refile arrangements, the FCC could find by its
own actions or in response to the filing of a third party, that certain of the
Company's transit or refile arrangements violate the ISP or other FCC policies.
In that event, the FCC could order the Company to terminate any non-conforming
transit or refile arrangements. In addition, the Company could be subject to a
monetary forfeiture and to other penalties, including revocation of the
Company's FCC authorizations to operate as an international carrier. Any such
FCC action could have a material adverse effect on the Company's business,
operating results and financial condition.

    REPORTING REQUIREMENTS.  International telecommunication carriers also are
required by the FCC's rules timely to file certain reports regarding
international traffic and revenues, the ownership and use of international
facilities and their affiliates with foreign carriers. The FCC considers a U.S.
carrier to be affiliated with a foreign carrier if it has a 25% interest in the
capital stock of the carrier or it controls the foreign carrier or is under
common ownership or control. The FCC requires these reports so that, among other
things, it may monitor the development of industry competition and the potential
for a dominant foreign carrier to discriminate amongst U.S. carriers. The
Company generally has filed said traffic, facilities and foreign affiliation
reports. The FCC's rules require international telecommunication carriers to
file at the FCC copies of their contracts with other carriers, including
operating agreements, within 30 days of execution. The Company has filed copies
of its operating agreements with the FCC. Competitive U.S. international
carriers do not routinely file other carrier-to-carrier contracts with the FCC
and, consistent with industry practice, the Company has not filed certain other
carrier contracts. Notwithstanding the foregoing FCC filings by the Company, the
FCC by its own action or in response to the filing of a third party could
determine that the Company has failed to meet certain of the foregoing filing
and reporting requirements or that certain Company filings are deficient. In
that event, the Company could be directed to remedy any asserted non-compliance;
the Company could also be subject to a monetary forfeiture and to other
penalties, and, although the Company believes that it would be largely
unprecedented in such circumstances, and hence unlikely, the FCC could revoke
the Company's authorizations to operate as an international carrier. Any such
FCC action could have a material adverse affect on the Company's business,
results and financial condition.
 
    REGULATORY FEES.  The Communications Act and FCC rules and policies impose
certain fees upon carriers providing interstate and international
telecommunication services. These fees are levied, among other things, to defray
the FCC's operating expenses, to underwrite universal telecommunication service
(e.g., by subsidizing certain services used by schools and libraries, such as
Internet access, and by other telecommunications users in areas of the U.S.
where service costs are significantly above average), to fund the
Telecommunications Relay Service ("TRS"), which provides special options for
hearing-impaired users, and to support the administration of telephone numbering
plans.
 
    Carriers that provide domestic interstate services must pay an annual
regulatory fee based on their interstate revenues; the fee is currently 0.12% of
revenue. The bulk of the Company's revenue, which is derived from international
services, is not subject to this fee. Carriers that provide domestic interstate
services to end users must pay a universal telecommunications service fee each
month based upon the total estimated demand for U.S. universal service funding.
If applicable, each carrier's share is approximately four percent of the
carrier's annual end user revenues. The Company generally offers its services
only to other carriers which in turn provide services to end-users. Such
carrier-to-carrier revenues are not subject to universal service fees, and thus
the Company generally is not liable to pay universal service fees. Carriers that
only offer international service (i.e., service between the United States and a
foreign country or service between two foreign carriers) also are not subject to
the universal service fee. However, if an international carrier has an affiliate
that provides domestic interstate services, then the carrier's international
revenues are subject to said fee. Until its acquisition of LDS, the Company did
not offer domestic interstate services. As a result of the operations of LDS,
any revenue the Company receives from end users for international services may
be subject to universal service fees. U.S. interstate and international carriers
must pay a percentage of their total revenue each year to support the North
American Numbering Plan Administrator. For the 1998 filing year, the
contribution rate is less than .003 percent of net telecommunications revenue.
U.S. carriers must pay a certain percentage of their domestic interstate
revenues to support the TRS Fund. For the 1998 filing year, the contribution
rate is less than .04 percent of gross domestic interstate revenue. The Company
has routinely paid the foregoing regulatory fees and, with regard to the annual
regulatory fees owed by interstate carriers, the Company is currently owed
approximately $20,000 by the FCC due to the inadvertent overpayment of said fee
for a prior year. The foregoing regulatory fees typically change annually. The
Company cannot predict the future regulatory fees for which it may be liable.
Said fees could rise significantly for the Company and amount to four percent or
more of the
 
                                       40
<PAGE>
Company's gross international and interstate revenues if the Company is no
longer exempt from paying universal service fees as a result of an affiliate's
provision of domestic interstate services, or because the Company provides
service directly to end users, or because amendments to the Communications Act
repeal the universal service fee exemption for carriers which only offer
international service or services provided to connecting carriers. Because the
international telecommunication services business is highly competitive, an
increase in the regulatory fees which the Company must pay could impair its
market position and have a material adverse effect on the Company's business,
operating results and financial condition.
 
    RECENT AND POTENTIAL FCC ACTIONS.  Recent FCC rulemaking orders and other
actions have lowered the entry barriers for new facilities-based and resale
international carriers by streamlining the processing of new applications and
granting non-dominant carriers greater flexibility in establishing non-standard
settlement arrangements with non-dominant foreign carriers, including the
non-dominant U.S. affiliates of such carriers. In addition, the FCC's rules
implementing the WTO Agreement presume that competition will be advanced by the
U.S. entry of facilities-based and resale carriers from WTO member countries,
thus further increasing the number of potential competitors in the U.S. market
and the number of carriers which may also offer end-to-end services. The FCC is
reviewing the proposed merger of WorldCom and MCI, and is expected soon to
review the proposed merger of LCI International, Inc. and Qwest Communications
International Inc. FCC approval and consummation of these mergers would increase
concentration in the international telecommunications service industry and the
potential market power of the Company's competitors. The FCC also recently has
sought to reduce the foreign termination costs of U.S. international carriers by
prescribing maximum or benchmark settlement rates which foreign carriers may
charge U.S. carriers for terminating switched telecommunications traffic and, if
the FCC's benchmarks order survives judicial review, the FCC's action may reduce
the Company's settlement costs, although the costs of other U.S. international
carriers also may be reduced in a similar fashion. The FCC has not stated how it
will enforce the new settlement benchmarks if U.S. carriers are unsuccessful in
negotiating settlement rates at or below the prescribed benchmarks, but any
future FCC intervention could disrupt the Company's transmission arrangements to
certain countries or require the Company to modify its existing arrangements;
other U.S. international carriers might be similarly affected. The 1996
amendment to the Communications Act permits the FCC to forbear enforcement of
the tariff provisions in the Act, which apply to all interstate and
international carriers, and the U.S. Court of Appeals is currently reviewing an
FCC order directing all domestic interstate carriers to detariff their
offerings. Subject to the Court's decision, the FCC may forbear its current
tariff rules for U.S. international carriers, such as the Company, or order such
carriers to detariff their services. In that event, the Company would have
greater flexibility in pricing its service offerings and to compete, although
any such FCC action likely would grant other non-dominant international carriers
equivalent freedom. The FCC routinely reviews the contribution rate for various
levels of regulatory fees, including the rate for fees levied to support
universal service, which fees may be increased in the future for various
reasons, including the need to support the universal service programs mandated
by the Communications Act, the total costs for which are still under review by
the FCC. The FCC also is reviewing the extent to which international carriers
may refile traffic using international private line facilities or otherwise.
Future FCC actions regarding refile could affect the Company by, for example,
requiring it to discontinue certain termination arrangements which it now has or
to implement alternative routing arrangements for certain countries; on the
other hand, the FCC may further liberalize its existing rules and policies
regarding refile in which case the Company is likely to be well positioned to
expand certain refile operations even though new opportunities may become
available to its competitors. The Company can not predict the net effect of
these or other possible future FCC actions on its business, operating results
and financial condition, although the net effect could be material.
 
STATE REGULATION
 
    STATE.  The intrastate long distance telecommunications operations of STAR
and its subsidiaries are subject to various state laws and regulations,
including prior certification, notification, registration and/or
 
                                       41
<PAGE>
tariff requirements. In certain states, prior regulatory approval is required
for changes in control of telecommunications services. The vast majority of
states require STAR and its subsidiaries to apply for certification to provide
intrastate telecommunications services, or at a minimum to register or to be
found to be exempt from regulation, prior to commencing sale of intrastate
services. Additionally, the vast majority of states require STAR or its
subsidiaries to file and maintain detailed tariffs setting forth rates charged
by STAR to its end-users for intrastate services. Many states also impose
various reporting requirements and/or require prior approval for transfers of
control of certificated carriers and assignments of carrier assets, including
customer bases, carrier stock offerings, and incurrence by carriers of
significant debt. Certificates of authority can generally be conditioned,
modified, canceled, terminated or revoked by state regulatory authorities for
failure to comply with state laws and/or rules, regulations and policies of the
state regulatory authorities. Fines and other penalties, including, for example,
the return of all monies received for intrastate traffic from residents of a
state in which a violation has occurred may be imposed.
 
    STAR, along with its regulated subsidiaries, believes it has made the
filings and taken the actions it believes are necessary to provide the
intrastate services it currently provides to end users throughout the U.S. STAR
and/or its subsidiaries are qualified to do business as foreign corporations,
and have received certification to provide intrastate telecommunications
services in all states where certification is required, and have received
approval for changes of control where such approvals are necessary. The Company
and its subsidiaries are required to make periodic filings in order to maintain
certificated status and remain qualified as foreign corporations.
 
    In early 1997, the FCC instituted significant changes to the current
incumbent local exchange carrier access charge structure. These changes were
meant, in part, to bring access charges closer to their actual costs. While
there has been a general trend towards access charge reductions, new primary
interexchange carrier charges (PICCs) were authorized by the FCC to be imposed
on interexchange carriers serving presubscribed access charges closer to their
actual costs. PICCs are a flat-rated, per presubscribed line, per month access
charge imposed upon all facilities-based carriers (although they may be passed
through to resellers). Facilities-based carriers were assessed interstate PICCs
effective January 1, 1998. Intrastate PICCs have also been adopted in the five
state Ameritech region (Michigan, Wisconsin, Illinois, Indiana, and Ohio), and
may be adopted elsewhere. At the same time, the Company may pursue underlying
carriers for pass throughs of any access charge reductions they may realize from
incumbent local exchange carriers.
 
    ACTIONS AGAINST LDS.  In 1997, prior to the Company's acquisition of LDS,
LDS settled disputes with the California PUC and with the District Attorney of
Monterey, California regarding LDS' alleged unauthorized switching of long
distance customers. As part of the Settlements, LDS was subject to fines and
restrictions on its business operations in California. In addition, the FCC has
received numerous informal complaints against LDS regarding the alleged
unauthorized switching of long distance customers, which complaints currently
remain under review.
 
    Following the Company's acquisition of LDS and in order to comply with the
Settlements, STAR has imposed strict restrictions on certain former LDS
employees, restricting these employees with respect to California intrastate
telecommunications operations. Additionally, the Company has taken a number of
steps to reduce the risk of a repeat occurrence regarding the alleged
unauthorized switching of commercial customers in California. There can,
however, be no assurance that LDS or STAR will not be subject to further
regulatory review by the California PUC or the FCC.
 
FOREIGN REGULATION
 
    UNITED KINGDOM.  In the U.K., telecommunications services offered by the
Company through its affiliate, STAR Europe Ltd., are subject to regulation by
various U.K. regulatory agencies. The U.K. generally permits competition in all
sectors of the telecommunications market, subject to licensing requirements and
license conditions. The Company has been granted licenses to provide
international traffic on a resale basis and over its own facilities, which
licenses are subject to a number of restrictions.
 
                                       42
<PAGE>
Implementation of these licenses have permitted the Company to engage in
cost-effective routing of traffic between the U.S. and the U.K. and beyond.
 
    GERMANY.  In Germany, telecommunications services offered by the Company
through its affiliate, STAR Telecommunications Deutschland GmbH ("STAR
Germany"), are subject to regulation by the Regulierungsbehorde fur
Telekommunikation und Post (which is under the jurisdiction of the Ministry of
Economy). Germany permits the competitive provision of international
facilities-based and resale services. STAR Germany was granted a license for the
provision of voice telephony on the basis of self-operated telecommunications
networks on December 4, 1997. Under this license, STAR Germany is presently
installing telecommunications switching facilities in Dusseldorf, Frankfurt,
Hamburg and Munich and is leasing connection transmission facilities between
these switches and additional facilities. The network of STAR Germany will be
used primarily for routing international telecommunications traffic between the
U.S., the U.K., Germany and beyond. There can be no assurance that future
changes in regulation of the services provided by STAR Germany will not have a
material adverse effect on the Company's business, operating results and
financial condition.
 
    OTHER COUNTRIES.  The Company plans to initiate a variety of services in
certain European countries including France and Belgium. These services will
include value-added services to closed user groups and other voice services as
regulatory liberalization in those countries permits. These and other countries
have announced plans or adopted laws to permit varying levels of competition in
the telecommunications market. Under the terms of the WTO Agreement, each of the
signatories has committed to opening its telecommunications market to
competition, foreign ownership and to adopt measures to protect against
anticompetitive behavior, effective starting on January 1, 1998. Although the
Company plans to obtain authority to provide service under current and future
laws of those countries, or, where permitted, provide service without government
authorization, there can be no assurance that foreign laws will be adopted and
implemented providing the Company with effective practical opportunities to
compete in these countries. Moreover, there can be no assurance of the nature
and pace of liberalization in any of these markets. The Company's inability to
take advantage of such liberalization could have a material adverse affect on
the Company's ability to expand its services as planned.
 
EMPLOYEES
 
    As of March 1, 1998, the Company employed 454 full-time employees. The
Company is not subject to any collective bargaining agreement and it believes
that its relationships with its employees are good.
 
PROPERTIES
 
    The Company's principal offices are located in Santa Barbara, California in
four facilities providing an aggregate of approximately 17,659 square feet of
office space. Approximately 5,332 square feet of this office space is leased
pursuant to two leases that both expire in July 1999. The remaining
approximately 12,327 square feet of office space is located in two buildings and
is rented by the Company pursuant to a lease that expires in June 2003. The
Company also leases approximately 16,595 square feet of space for its switching
facility in Los Angeles, California under a sublease and a lease expiring in
April 2006, an aggregate of approximately 33,445 square feet of space for its
switching facilities in New York, New York under three leases which expire in
December 31, 2001, July 31, 2003 and April 2008, respectively, approximately
6,167 square feet of space for its switching facility in Dallas, Texas under a
lease expiring in April 2007, and approximately 8,000 square feet of space for
its switching facility in London, England under a lease expiring in July 2006.
The Company leases approximately 14,628 square feet in Dusseldorf, approximately
27,835 square feet in Frankfurt, approximately 12,002 square feet in Hamburg and
approximately 12,408 square feet in Munich, Germany under four leases expiring
on or about January 1, 2008. The aggregate facility lease payments made by the
Company in 1997 were approximately $2.2 million. The Company believes that all
other material terms of its leases are commercially reasonable terms that are
typically found in commercial leases in each of the respective areas in which
the Company leases space.
 
                                       43
<PAGE>
The Company believes that its facilities are adequate to support its current
needs and that additional facilities will be available at competitive rates as
needed.
 
LITIGATION
 
    The Company is not presently a party to any material pending litigation.
From time to time, however, the Company is party to various legal proceedings,
including billing disputes and collection matters, that arise in the ordinary
course of business.

BOARD COMPOSITION
 
    In accordance with the terms of the Company's Amended and Restated
Certificate of Incorporation, the terms of office of the Board of Directors are
divided into three classes: Class I, whose term will expire at the annual
meeting of stockholders to be held in 1998; Class II, whose term will expire at
the annual meeting of stockholders to be held in 1999; and Class III, whose term
will expire at the annual meeting of stockholders to be held in 2000. The Class
I directors are Gordon Hutchins, Jr. and John R. Snedegar, the Class II
directors are Mark Gershien and Mary A. Casey, and the Class III director is
Christopher E. Edgecomb. At each annual meeting of stockholders after the
initial classification, the successors to directors whose term will then expire
will be elected to serve from the time of election and qualification until the
third annual meeting following election. This classification of the Board of
Directors may have the effect of delaying or preventing changes in control or
changes in management of the Company. See "Risk Factors--Anti-takeover Effects
of Certificate of Incorporation, Bylaws and Delaware Law" and "Description of
Capital Stock--Anti-takeover Effects of Provisions of the Certificate of
Incorporation, Bylaws and Delaware Law."
 
    Each officer is elected by and serves at the discretion of the Board of
Directors. Each of the Company's officers and directors, other than nonemployee
directors, devotes substantially full time to the affairs of the Company. The
Company's nonemployee directors devote such time to the affairs of the Company
as is necessary to discharge their duties. There are no family relationships
among any of the directors, officers or key employees of the Company.
 
DIRECTOR COMPENSATION
 
    The Company's non-employee directors receive $2,000 for each Board meeting
attended and $1,000 for each telephonic Board meeting. In addition, each
non-employee director is reimbursed for out-of-pocket expenses incurred in
connection with attendance at meetings of the Board of Directors and its
 
                                       46

committees. In 1996, Messrs. Hutchins and Snedegar were each granted stock
options to purchase 20,500 shares of Common Stock. In 1997, Messrs. Hutchins,
Snedegar and Roland Van der Meer, a former director, were each granted stock
options to purchase 10,250 shares of Common Stock. In 1998, Messrs. Hutchins,
Snedegar and Gershien were each granted stock options to purchase 10,250 shares
of Common Stock. See "Certain Transactions--Transactions with Outside
Directors."

(1) The 5% and 10% assumed annual rates of compounded stock price appreciation
    are mandated by rules of the Securities and Exchange Commission. There can
    be no assurance provided to any executive officer or any other holder of the
    Company's securities that the actual stock price appreciation over the
    10-year option term will be at the assumed 5% and 10% levels or at any other
    defined level. Unless the market price of the Common Stock appreciates over
    the option term, no value will be realized from the option grants made to
    the executive officer.
 
(2) The option becomes exercisable in four equal annual installments on June 26,
    1998, 1999, 2000 and 2001, respectively.
 
AGGREGATE OPTION EXERCISES IN LAST FISCAL YEAR AND FISCAL YEAR-END OPTION VALUES
 
    No options were exercised by the Named Officers for the fiscal year ended
December 31, 1997. No stock appreciation rights were exercised during such year
or were outstanding at the end of that year.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
    The Compensation Committee of the Company's Board (the "Compensation
Committee") was formed in May 1996, and, in 1997, the members of the
Compensation Committee were Gordon Hutchins, Jr., John R. Snedegar and Roland A.
Van der Meer. None of these individuals was at any time during the year ended
December 31, 1997, or at any other time, an officer or employee of the Company.
Mr. Van der Meer resigned from the Board and the Compensation Committee,
effective as of February 1, 1998. The Non-Executive Compensation Committee of
the Company's Board (the "Non-Executive Compensation Committee") was formed in
1997, and the members are Christopher E. Edgecomb and Mary A. Casey. No member
of the Compensation Committee or the Non-Executive Compensation Committee served
at any time during the year ended December 31, 1997 as a member of the board of
directors or compensation committee of any entity that has one or more executive
officers serving as a member of the Company's Board, Compensation Committee or
Non-Executive Compensation Committee. The Compensation Committee and the
Non-Executive Compensation Committee shall collectively be referred to hereafter
as the "Compensation Committees."
 
1997 OMNIBUS STOCK INCENTIVE PLAN
 
    The Company's 1997 Omnibus Stock Incentive Plan (the "Omnibus Plan") was
adopted by the Board of Directors on January 30, 1997 as the successor to the
Company's 1996 Supplemental Option Plan (the "Supplemental Plan"). The Company
has reserved 3,075,000 shares for issuance under the Omnibus Plan. This share
reserve is comprised of (i) the 2,050,000 shares that were available for
issuance under the Supplemental Plan, plus (ii) an increase of 1,025,000 shares.
As of February 28, 1998, 16,621 shares had been issued under the Supplemental
and Omnibus Plans, options for 2,143,045 shares were outstanding (889,413 of
which were granted under the Supplemental Plan) and approximately 915,330 shares
remained available for future grant. Shares of Common Stock subject to
outstanding options, including options
 
                                       48
<PAGE>
granted under the Supplemental Plan, which expire or terminate prior to
exercise, will be available for future issuance under the Omnibus Plan. In
addition, if stock appreciation rights ("SARs") and stock units are settled
under the Omnibus Plan, then only the number of shares actually issued in
settlement will reduce the number of shares available for future issuance under
this plan.
 
    Under the Omnibus Plan, employees, outside directors and consultants may be
awarded options to purchase shares of Common Stock, SARs, restricted shares and
stock units. Options may be incentive stock options designed to satisfy Section
422 of the Internal Revenue Code or nonstatutory stock options not designed to
meet such requirements. SARs may be awarded in combination with options,
restricted shares or stock units, and such an award may provide that the SARs
will not be exercisable unless the related options, restricted shares or stock
units are forfeited.
 
    The Omnibus Plan is administered by the Board or the Compensation Committees
(the "Administrator"). The Administrator has the complete discretion to
determine which eligible individuals are to receive awards; determine the award
type, number of shares subject to an award, vesting requirements and other
features and conditions of such awards; interpret the Omnibus Plan; and make all
other decisions relating to the operation of the Omnibus Plan.
 
    The exercise price for options granted under the Omnibus Plan may be paid in
cash or in outstanding shares of Common Stock. Options may also be exercised on
a cashless basis, by a pledge of shares to a broker or by promissory note. The
payment for the award of newly issued restricted shares will be made in cash. If
an award of SARs, stock units or restricted shares from the Company's treasury
is granted, no cash consideration is required.
 
    The Administrator has the authority to modify, extend or assume outstanding
options and SARs or may accept the cancellation of outstanding options and SARs
in return for the grant of new options or SARs for the same or a different
number of shares and at the same or a different exercise price.
 
    The Board may determine that an outside director may elect to receive his or
her annual retainer payments and meeting fees from the Company in the form of
cash, options, restricted shares, stock units or a combination thereof. The
Board will decide how to determine the number and terms of the options,
restricted shares or stock units to be granted to outside directors in lieu of
annual retainers and meeting fees.
 
    Upon a change in control, the Administrator may determine that an option or
SAR will become fully exercisable as to all shares subject to such option or
SAR. A change in control includes a merger or consolidation of the Company,
certain changes in the composition of the Board and acquisition of 50% or more
of the combined voting power of the Company's outstanding stock. In the event of
a merger or other reorganization, outstanding options, SARs, restricted shares
and stock units will be subject to the agreement of merger or reorganization,
which may provide for the assumption of outstanding awards by the surviving
corporation or its parent, their continuation by the Company (if the Company is
the surviving corporation), accelerated vesting and accelerated expiration, or
settlement in cash.
 
    The Board may amend or terminate the Omnibus Plan at any time. Amendments
may be subject to stockholder approval to the extent required by applicable
laws. In any event, the Omnibus Plan will terminate on January 22, 2007, unless
sooner terminated by the Board.
 
1996 OUTSIDE DIRECTOR NONSTATUTORY STOCK OPTION PLAN
 
    The Company's 1996 Outside Director Nonstatutory Stock Option Plan (the
"Director Plan") was ratified and approved by the Board of Directors as of May
14, 1996. The Company has reserved 410,000 shares of Common Stock for issuance
under the Director Plan. As of February 28, 1998, 61,500 shares had been issued
under the Director Plan, options for 82,000 shares were outstanding and 266,500
shares remained available for future grant. If an outstanding option expires or
terminates unexercised, then the shares subject to such option will again be
available for issuance under the Director Plan.
 
                                       49
<PAGE>
    Under the Director Plan, outside directors of the Company may receive
nonstatutory options to purchase shares of Common Stock. The Director Plan is
administered by the Board or the Compensation Committee (the "Administrator").
The Administrator has the discretion to determine which eligible individuals
will receive options, the number of shares subject to each option, vesting
requirements and any other terms and conditions of such options.
 
    The exercise price for options granted under the Director Plan will be at
least 85% of the fair market value of the Common Stock on the option grant date,
shall be 110% of the fair market value of the Common Stock on the option grant
date if the option is granted to a holder of more than 10% of the Common Stock
outstanding and may be paid in cash, check or shares of Common Stock. The
exercise price may also be paid by cashless exercise or pledge of shares to a
broker.
 
    The Administrator may modify, extend or renew outstanding options or accept
the surrender of such options in exchange for the grant of new options, subject
to the consent of the affected optionee.
 
    Upon a change in control, the Board may accelerate the exercisability of
outstanding options and provide an exercise period during which such accelerated
options may be exercised. The Board also has the discretion to terminate any
outstanding options that had been accelerated and had not been exercised during
such exercise period. In the event of a merger of the Company into another
corporation in which holders of Common Stock receive cash for their shares, the
Board may settle the option with a cash payment equal to the difference between
the exercise price and the amount paid to holders of Common Stock pursuant to
the merger.
 
    The Board may amend or terminate the Director Plan at any time. In any
event, the Director Plan will terminate on May 14, 2006, unless sooner
terminated by the Board.
 
EMPLOYMENT AGREEMENTS AND CHANGE OF CONTROL ARRANGEMENTS
 
    The Company has an employment agreement with Mary A. Casey, pursuant to
which Ms. Casey holds the position of President of the Company, is paid an
annual salary of $20,000 per month, subject to adjustment to reflect increases

Officer and Board of Directors. The agreement also provides that Ms. Casey will
receive a severance payment equal to $7,000 per month for the first six months
after termination of employment, and an additional payment of $7,000 per month
for the next six months, minus any amounts earned by her from other employment
during such period. In addition, the agreement provides that if Ms. Casey's
employment is terminated (other than for cause) within four months after a Sale
Transaction (as defined below), she will continue to receive the compensation
provided in the agreement until the expiration of the agreement on December 31,
2000, instead of the severance payments described above. A Sale Transaction is
an acquisition of more than 75% of the voting securities of STAR, pursuant to a
tender offer or exchange offer approved in advance by the Board of Directors.
 
    In January 1996, the Company entered into an employment agreement with David
Vaun Crumly pursuant to which Mr. Crumly became Executive Vice President of the
Company. The agreement provides for an annual salary of $10,000 per month with
an annual increase, plus incentive bonuses tied to gross revenues of the
Company. The agreement also provides for a commission on certain accounts of the
Company and an option to purchase 369,000 shares of Common Stock at an exercise
price of $0.73 per share. In addition, in the event of a Sale Transaction, Mr.
Crumly will receive a bonus payment equal to the lesser of $1,500,000 or a
percentage of the monthly gross sales of accounts relating to customers
introduced to the Company by Mr. Crumly. If his employment is terminated in
certain circumstances, without cause, within four months after a Sale
Transaction, Mr. Crumly is entitled to receive the compensation provided in this
agreement, minus any compensation earned by other employment, until the
expiration of the agreement on December 31, 2000.
 
                                       50
<PAGE>
    In December 1996, the Company entered into an employment agreement with
Kelly D. Enos, pursuant to which Ms. Enos became Chief Financial Officer of the
Company. The agreement provides for an annual salary of $150,000 (which has been
increased to $160,000) and an option to purchase 153,750 shares of Common Stock
at an exercise price of $4.00 per share. The agreement also provides that Ms.
Enos will receive a severance payment equal to the compensation which she would
have received under the remaining term of the agreement if she terminates the
agreement as a result of STAR's default of its material obligations and duties
under the agreement or if she is terminated by the Company without cause within
four months after a Sale Transaction.
 
    In September 1996, STAR entered into an employment agreement with James
Kolsrud, pursuant to which Mr. Kolsrud became Executive Vice
President--Operations and Engineering of STAR. The agreement provides for a
monthly salary of $16,667, an option to purchase 205,000 shares of Common Stock
pursuant to the Company's 1996 Supplemental Stock Option Plan at a price of
$4.00 per share, reimbursement of reasonable out-of-pocket expenses incurred in
connection with Company business, and fringe benefits accorded to executives of
the Company as determined by the Board of Directors. In the event of termination
pursuant to the agreement, Mr. Kolsrud shall be entitled to receive compensation
accrued and payable to him as of the date of his termination or death, and all
other amounts payable to him under the agreement shall thereupon cease. If his
employment is terminated in certain circumstances within four months after a
Sale Transaction, then Mr. Kolsrud shall continue to receive the compensation
provided in the agreement until the expiration of the agreement on December 31,
2000.

                              CERTAIN TRANSACTIONS
 
TRANSACTIONS WITH OUTSIDE DIRECTORS
 
    The Company provided services to Digital Network, Inc. ("DNI") in the amount
of approximately $1,141,000 in 1997. DNI is a wholly owned subsidiary of UDN,
and John R. Snedegar, a Director of the Company, is President of UDN. On
November 19, 1997, the Company entered into an agreement to acquire UDN. Messrs.
Snedegar and Edgecomb beneficially own 11% and 2%, respectively, of the
outstanding common stock of UDN. In the context of the potential acquisition of
UDN, the Company has loaned $4.5 million to UDN at market rates of interest.
Assumming the receipt of all necessary stockholder and regulatory approvals,
management expects to consummate the UDN acquisition in the second quarter of
1998 for approximately 800,000 shares of Common Stock. Prior to consummation of
the acquisition of UDN, the Company will receive a fairness opinion from an
investment banking firm that the consideration paid was fair, from a financial
point of view, to the stockholders of the Company. UDN's Common Stock is traded
on the Vancouver Stock Exchange under the symbol UDN.
 
    GH Associates, an affiliate of Gordon Hutchins Jr., a Director of the
Company, provides consulting services to the Company. In 1995, 1996 and 1997,
the Company made payments of approximately $60,000, $154,000 and $72,000,
respectively, to GH Associates for general business consulting services relating
to the telecommunications industry and for the performance of other tasks
requested by the Company's Chief Executive Officer, President and Board of
Directors. In addition, in connection with these services, the Company granted
to Mr. Hutchins a nonstatutory option to purchase 205,000 shares of Common Stock
at an exercise price of $1.46 per share.
 
    The Company's Outside Directors have been granted nonstatutory stock options
under the Director Plan. See "Management--Director Compensation."
 
TRANSACTIONS WITH EXECUTIVE OFFICERS
 
    In January 1998, the Company granted to each of Kelly Enos, David Vaun
Crumly and James Kolsrud incentive stock options to purchase 4,100 shares of
Common Stock at an exercise price of $16.31.
 
    On October 4, 1996, the Company entered into a $12.0 million line of credit
with Comerica Bank. This line of credit was guaranteed by Christopher E.
Edgecomb, the Company's Chief Executive Officer. The Company has entered into a
new revolving credit facility since that time and Mr. Edgecomb's guarantee of
the Comerica Bank line has been terminated. Mr. Edgecomb did not receive any
additional compensation in connection with such guarantee. STAR has entered into
lines of credit with Mr. Edgecomb in the aggregate amount of $1,448,000 that
expire on March 30, 1998. Borrowings under the lines of credit bear interest at
a rate of 9.0% and there was $138,000 outstanding under these lines of credit as
of December 31, 1997. In addition, on November 27, 1997 the Company provided a
short-term loan to Mr. Edgecomb for $8.0 million. The loan carried interest of
7% per annum and was repaid in seven days.
 
    Mr. Edgecomb owns Star Aero Services, Inc. ("Star Aero"), which has
ownership interests in five airplanes that the Company utilizes for business
travel from time to time. For the years ended December 31, 1995, 1996 and 1997,
the Company paid $144,000, $68,000 and $171,000, respectively, in costs related
to the use of Star Aero services.
 
    Mr. Crumly had controlling ownership of three companies that resold
transmission capacity to the Company during 1996 for a total of approximately
$240,000. No fees were paid to Mr. Crumly during 1997 with respect to such
transmission capacity. In addition, the Company has agreed to reimburse legal
fees incurred by such companies in connection with a dispute with the provider
of the capacity that was resold to the Company. To date, the fees paid or
incurred total approximately $131,000.
 
    Mr. Kolsrud has a 25% interest in Interpacket Group, Inc. ("Interpacket")
which has direct termination arrangements with the Company for certain countries
in Central and South America. For the years
 
                                       52
<PAGE>
ended December 31, 1996 and 1997, the Company paid $37,000 and $256,000,
respectively, for services rendered by Interpacket. In addition, the Company
purchased satellite transmission equipment and services from Interpacket during
1997 in the amount of $1,114,000.
 
INDEMNIFICATION
 
    The Company's Amended and Restated Certificate of Incorporation limits the
liability of its directors for monetary damages arising from a breach of their
fiduciary duty as directors, except to the extent otherwise required by the
Delaware General Corporation Law. Such limitation of liability does not affect
the availability of equitable remedies such as injunctive relief or rescission.
 
    The Company's Bylaws provide that the Company shall indemnify its directors
and officers to the fullest extent permitted by Delaware law, including in
circumstances in which indemnification is otherwise discretionary under Delaware
law. The Company's has also entered into or will enter into indemnification
agreements with its officers and directors containing provisions that may
require the Company, among other things, to indemnify such officers and
directors against certain liabilities that may arise by reason of their status
or service as directors or officers (other than liabilities arising from willful
misconduct of a culpable nature), to advance their expenses incurred as a result
of any proceeding against them as to which they could be indemnified, and to
obtain directors' and officers' insurance if available on reasonable terms.
 
    The Company believes that all of the transactions set forth above were made
on terms no less favorable to the Company than could have been obtained from
unaffiliated third parties. All future transactions, including loans between the
Company and its officers, directors, principal stockholders and their affiliates
will be approved by a majority of the Board of Directors, including a majority
of the independent and disinterested outside directors on the Board of
Directors, and will continue to be on terms no less favorable to the Company
than could be obtained from unaffiliated third parties.

                          DESCRIPTION OF CAPITAL STOCK
 
    The authorized capital stock of the Company consists of 50,000,000 shares of
Common Stock, $0.001 par value, and 5,000,000 shares of Preferred Stock, $0.001
par value.
 
COMMON STOCK
 
    As of March 16, 1998, there were approximately 35,804,000 shares of Common
Stock outstanding that were held of record by approximately 155 stockholders.
There will be approximately 42,804,000 shares of Common Stock outstanding
(assuming no exercise of the Underwriters' over-allotment option and assuming no
exercise after February 28, 1998, of outstanding options) after giving effect to
the sale of shares of Common Stock to the public offered hereby.
 
    The holders of Common Stock are entitled to one vote per share on all
matters to be voted upon by the stockholders. Subject to preferences that may be
applicable to any outstanding Preferred Stock, the holders of Common Stock are
entitled to receive ratably such dividends, if any, as may be declared from time
to time by the Company's Board of Directors out of funds legally available
therefor. See "Dividend Policy." In the event of the liquidation, dissolution,
or winding up of the Company, the holders of Common Stock are entitled to share
ratably in all assets remaining after payment of liabilities, subject to prior
distribution rights of Preferred Stock, if any, then outstanding. The Common
Stock has no preemptive or conversion rights or other subscription rights. There
are no redemption or sinking fund provisions applicable to the Common Stock. All
outstanding shares of Common Stock are fully paid and nonassessable, and the
shares of Common Stock to be issued upon completion of this offering will be
fully paid and nonassessable.
 
PREFERRED STOCK
 
    Pursuant to the Company's Amended and Restated Certificate of Incorporation,
the Board of Directors has the authority to issue up to 5,000,000 shares of
Preferred Stock in one or more series and to fix the rights, preferences,
privileges and restrictions thereof, including dividend rights, dividend rates,
conversion rights, voting rights, terms of redemption, redemption prices,
liquidation preferences and the number of shares constituting any series or the
designation of such series, without further vote or action by the stockholders.
The issuance of Preferred Stock may have the effect of delaying, deferring or
preventing a change in control of the Company without further action by the
stockholders and may adversely affect the voting and other rights of the holders
of Common Stock. The issuance of Preferred Stock with voting and conversion
rights may adversely affect the voting power of the holders of Common Stock,
including the loss of voting control to others. At present, the Company has no
plans to issue any of the Preferred Stock.
 
ANTI-TAKEOVER EFFECTS OF PROVISIONS OF THE CERTIFICATE OF INCORPORATION, BYLAWS
  AND DELAWARE LAW
 
    CERTIFICATE OF INCORPORATION AND BYLAWS.  The Company's Amended and Restated
Certificate of Incorporation provides that the Board of Directors be divided
into three classes of directors, with each class serving a staggered three-year
term. The classification system of electing directors may tend to discourage a
third party from making a tender offer or otherwise attempting to obtain control
of the Company and may maintain the incumbency of the Board of Directors, as the
classification of the Board of Directors generally increases the difficulty of
replacing a majority of the directors. The Amended and Restated Certificate of
Incorporation also provides that all stockholder actions must be effected at a
duly called meeting and not by a consent in writing. Further, provisions of the
Bylaws and the Amended and Restated Certificate of Incorporation provide that
the stockholders may amend the Bylaws or certain provisions of the Amended and
Restated Certificate of Incorporation only with the affirmative vote of 75% of
the Company's capital stock. These provisions of the Amended and Restated
Certificate of Incorporation and Bylaws could discourage potential acquisition
proposals and could delay or prevent a change in control of the Company. These
provisions are intended to enhance the likelihood of continuity and
 
                                       56
<PAGE>
stability in the composition of the Board of Directors and in the policies
formulated by the Board of Directors and to discourage certain types of
transactions that may involve an actual or threatened change of control of the
Company. These provisions are designed to reduce the vulnerability of the
Company to an unsolicited acquisition proposal. The provisions also are intended
to discourage certain tactics that may be used in proxy fights. However, such
provisions could have the effect of discouraging others from making tender
offers for the Company's shares and, as a consequence, they also may inhibit
fluctuations in the market price of the Company's shares that could result from
actual or rumored takeover attempts. Such provisions also may have the effect of
preventing changes in the management of the Company. See "Risk Factors--Effect
of Certain Charter Provisions; Anti-takeover Effects of Certificate of
Incorporation, Bylaws and Delaware Law."
 
    DELAWARE TAKEOVER STATUTE.  The Company is subject to Section 203 of the
Delaware General Corporation Law ("Section 203"), which, subject to certain
exceptions, prohibits a Delaware corporation from engaging in any business
combination with any interested stockholder for a period of three years
following the date that such stockholder became an interested stockholder,
unless: (i) prior to such date, the board of directors of the corporation
approved either the business combination or the transaction that resulted in the
stockholder becoming an interested stockholder; (ii) upon consummation of the
transaction that resulted in the stockholder becoming an interested stockholder,
the interested stockholder owned at least 85% of the voting stock of the
corporation outstanding at the time the transaction commenced, excluding for
purposes of determining the number of shares outstanding those shares owned (x)
by persons who are directors and also officers and (y) by employee stock plans
in which employee participants do not have the right to determine confidentially
whether shares held subject to the plan will be tendered in a tender or exchange
offer; or (iii) on or subsequent to such date, the business combination is
approved by the board of directors and authorized at an annual or special
meeting of stockholders, and not by written consent, by the affirmative vote of
at least 66 2/3% of the outstanding voting stock that is not owned by the
interested stockholder.
 
    Section 203 defines business combination to include: (i) any merger or
consolidation involving the corporation and the interested stockholder; (ii) any
sale, transfer, pledge or other disposition of 10% or more of the assets of the
corporation involving the interested stockholder; (iii) subject to certain
exceptions, any transaction that results in the issuance or transfer by the
corporation of any stock of the corporation to the interested stockholder; (iv)
any transaction involving the corporation that has the effect of increasing the
proportionate share of the stock of any class or series of the corporation
beneficially owned by the interested stockholder; or (v) the receipt by the
interested stockholder of the benefit of any loans, advances, guarantees,
pledges or other financial benefits provided by or through the corporation. In
general, Section 203 defines an interested stockholder as any entity or person
beneficially owning 15% or more of the outstanding voting stock of the
corporation and any entity or person affiliated with or controlling or
controlled by such entity or person.
 
REGISTRATION RIGHTS

    Approximately 849,000 shares issued in the LDS acquisition will be available

    In general, under Rule 144 as currently in effect, a person (or persons
whose shares are aggregated) who has beneficially owned shares for at least one
year is entitled to sell within any three-month period a number of such shares
that does not exceed the greater of (i) 1% of the then outstanding shares of
Common Stock (approximately 428,000 shares immediately after the offering) or
(ii) the average weekly trading volume during the four calendar weeks preceding

person (or persons whose shares are aggregated) who is not deemed to have been

the sale who has beneficially owned his or her shares for at least two years is
entitled to sell such shares pursuant to Rule 144(k) without regard to the
limitations described above. Persons deemed to be affiliates must always sell
pursuant to Rule 144, even after the applicable holding periods have been
satisfied.
 
    The Company, its directors, executive officers and certain other
stockholders have agreed pursuant to the Underwriting Agreement and other
agreements that they will not sell any Common Stock without the prior consent of
BT Alex. Brown Incorporated for a period of in some cases 45 days and in other

    The Company has filed a registration statement under the Securities Act to

vested options under any of such Plans may be sold in the public market,
subject, in the case of directors, officers and other affiliates, to the volume

volume and other limitations.
 
    In addition, after this offering, the holders of approximately 7,153,000

    The Underwriting Agreement provides that the obligations of the Underwriters
are subject to certain conditions precedent and that the Underwriters will
purchase all shares of the Common Stock offered hereby if any of such shares are
purchased.
 
    The Company and the Selling Stockholder have been advised by the
Representatives that the Underwriters propose to offer the shares of Common
Stock directly to the public at the public offering price set forth on the cover
page of this Prospectus and to certain dealers at such price less a concession
not in excess of $      per share. The Underwriters may allow and such dealers
may reallow, a concession not in excess of $      per share to certain other
dealers. After the offering, the public offering price and other selling terms
may be changed by the Representatives.
 
    The Company and the Selling Stockholder have granted to the Underwriters an
option, exercisable no later than 30 days after the date of this Prospectus, to
purchase up to an aggregate of 1,050,000 additional shares of Common Stock at
the public offering price, less the underwriting discounts and commissions, set
forth on the cover page of this Prospectus. To the extent that the Underwriters
exercise such option, each of the Underwriters will have a firm commitment to
purchase approximately the same percentage of such additional shares as the
number of shares of Common Stock to be purchased by it shown in the above table
bears to the total number of shares of Common Stock offered hereby, and the
Company and the Selling Stockholder will be obligated, pursuant to the option,
to sell shares to the Underwriters if any. The Underwriters may exercise such
option only to cover over-allotments, if any, made in connection with the sale
of shares of Common Stock offered hereby. If purchased, the Underwriters will
offer such additional shares on the same terms as those on which the 7,000,000
shares are being offered.
 
    In connection with this offering, certain Underwriters may engage in passive
market making transactions in the Common Stock on the Nasdaq National Market
immediately prior to the commencement of sales in this offering in accordance
with Rule 103 of Regulation M. Passive market making consists of displaying bids
on the Nasdaq National Market limited by the bid prices of independent market
makers and making purchases limited by such prices and effected in response to
order flow. Net purchases by a passive market maker on each day are limited to a
specified percentage of the passive market maker's average daily trading volume
in the Common Stock during a specified period and must be discontinued when such
limit is reached. Passive market making may stabilize the market price of the
Common Stock at a level above that which might otherwise prevail and, if
commenced, may be discontinued at any time.
 
    Subject to applicable limitations, the Underwriters, in connection with this
offering, may place bids for or make purchases of the Common Stock in the open
market or otherwise, for long or short account or
 
                                       60
<PAGE>
cover short positions incurred, to stabilize, maintain or otherwise affect the
price of the Common Stock, which may be higher than the price that might
otherwise prevail in the open market. There can be no assurance that the price
of the Common Stock will be stabilized, or that stabilizing, if commenced, will
not be discontinued at any time. Subject to applicable limitations, the
Underwriters may also place bids or make purchases on behalf of the underwriting
syndicate to reduce a short position created in connection with this Offering.
The Underwriters are not required to engage in these activities and may end
these activities at any time.
 
    The Underwriting Agreement contains certain covenants of indemnity among the
Underwriters, the Company and the Selling Stockholders against certain civil,
liabilities, including liabilities under the Securities Act of 1933, as amended.
 
    The Company, each of its directors and executive officers and certain
stockholders, who in the aggregate will beneficially own, following this
offering, approximately 20,821,000 shares of Common Stock (including options to
purchase shares of Common Stock that are currently exercisable or exercisable
within 60 days of March 24, 1998), have agreed that they will not, directly or
indirectly, without the prior written consent of BT Alex. Brown Incorporated,

To STAR Telecommunications, Inc.:
 
    After the stock split discussed in Note 14 of the Notes to Consolidated
Financial Statements is effected, we expect to be in a position to render the
following audit report.
 
                                          ARTHUR ANDERSEN LLP

                   "REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Board of Directors and Stockholders
  of STAR Telecommunications, Inc. and Subsidiaries:
 
    We have audited the accompanying consolidated balance sheets of STAR
TELECOMMUNICATIONS, INC. (a Delaware corporation) AND SUBSIDIARIES, as of
December 31, 1996 and 1997, and the related consolidated statements of
operations, stockholders' equity and cash flows for each of the three years in
the period ended December 31, 1997. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of STAR Telecommunications,
Inc. and Subsidiaries as of December 31, 1996 and 1997, and the results of their
operations and their cash flows for each of the three years in the period ended
December 31, 1997 in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                               DECEMBER 31, 1997
 
1. NATURE OF BUSINESS
 
    STAR Telecommunications, Inc., a Delaware corporation, and Subsidiaries (the
"Company" or "STAR"), is an emerging multinational carrier focused primarily on
the international long distance market. The Company offers highly reliable,
low-cost switched voice services on a wholesale basis primarily to U.S.-based
long distance carriers. STAR provides international long distance service
through a flexible network comprised of foreign termination relationships,
international gateway switches, leased and owned transmission facilities and
resale arrangements with other long distance providers. While the Company was
incorporated in 1993, it did not commence its current business as a provider of
long distance services until the second half of 1995. During the six months
ended June 1995, the Company primarily acted as an agent for, and provided
various consulting services to, companies in the telecommunications industry.
 
    During 1996 and 1997, the Company established several wholly-owned foreign
subsidiaries to further expand its international network. The Company made
substantial investments to install switch facilities in two of these
subsidiaries, Star Europe Limited (SEL) which is located in London, England, and
Star Telecommunications Deutschland (GmbH) which is located in Frankfurt,
Germany. The Company plans to use these switch facilities to decrease
international traffic termination costs and to initiate outbound calls from
these local markets.
 
    In December 1997, the Company entered into the domestic commercial
long-distance market through the acquisition of L.D. Services, Inc., also known
as LCCR Inc. ("LDS"). LDS is a retail long-distance service provider throughout
the United States. The merger constituted a tax-free reorganization and has been
accounted for as a pooling of interests under Accounting Principles Board
Opinion No. 16. Accordingly, all prior period consolidated financial statements
presented have been restated to include the results of operations, financial
position and cash flows of LDS as though it had always been a part of STAR (see
Note 8). The pro forma results of operations and pro forma income or loss per
common share for 1995, 1996 and 1997 assumes that both STAR and LDS had been
C-Corporations for all periods presented.
 
    The Company is subject to various risks in connection with the operation of
its business. These risks include, but are not limited to, regulations (both
domestic and foreign), dependence on transmission facilities-based carriers and
suppliers, price competition and competition from larger industry participants.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
    PRINCIPLES OF CONSOLIDATION
 
    The accompanying consolidated financial statements include the accounts of
STAR Telecommunications, Inc. and its wholly-owned subsidiaries. All significant
intercompany balances and transactions have been eliminated.
 
    REVENUE RECOGNITION
 
    The Company records revenues for telecommunications sales at the time of
customer usage. Finance charges for customer late payments are included in
revenues and amount to $32,000, $1,467,000 and $2,747,000 for the years ended
December 31, 1995, 1996 and 1997, respectively.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    COST OF SERVICES
 
    Cost of services for wholesale long distance services represents direct
charges from vendors that the Company incurs to deliver service to its
customers. These include leasing costs for the dedicated phone lines, which form
the Company's network, and rate-per-minute charges from other carriers that
terminate traffic on behalf of the Company. In addition, retail long distance
service cost includes billing and collection service fees from local exchange
carriers and call rating services.
 
    ACCOUNTING FOR INTERNATIONAL LONG DISTANCE TRAFFIC
 
    The Company has carrier service agreements with telecommunication carriers
in foreign countries under which international long distance traffic is both
originated and terminated on the Company's network. The Company records revenues
and related costs as the traffic is recorded in the switch. Revenue from foreign
customers equaled $178,000 and $6,577,000 for the years ended December 31, 1996
and 1997, respectively. The Company had no revenues from foreign customers
during 1995.
 
    CASH AND CASH EQUIVALENTS
 
    Cash and cash equivalents consist of demand deposits and money market funds,
which are highly liquid short-term instruments with original maturities of three
months or less from the date of purchase. Cash and cash equivalents are stated
at cost, which approximates market.
 
    FINANCIAL INSTRUMENTS
 
    The carrying amounts of notes payable and capital lease obligations
approximate their fair value because interest rates approximate market rates for
similar instruments.
 
    Off balance sheet derivative financial instruments at December 31, 1997
consist of foreign currency exchange agreements.
 
    The Company enters into foreign currency exchange contracts to manage
foreign currency exposures. The principle objective of such contracts is to
minimize the risks and/or costs associated with financial and global operating
activities. The Company does not utilize financial instruments for trading or
other speculative purposes. The counterparty to these contractual arrangements
is a multi-national financial institution with which the Company also has other
financial relationships.
 
    The Company enters into forward currency exchange contracts in the normal
course of business to manage its exposure against foreign currency fluctuations
on payable positions resulting from fixed asset purchases and other contractual
expenditures denominated in foreign currencies. At December 31, 1997, gains and
losses on foreign exchange contracts are not material to the consolidated
financial statements.
 
    The fair values of foreign currency contracts are estimated by obtaining
quotes from brokers. At December 31, 1997, the Company has foreign currency
contracts outstanding with the notional value of $6,305,000 which had an
estimated fair value to receive $6,218,000 worth of German marks and British
pounds, the difference of which has been recognized in operations.

    MARKETABLE SECURITIES
 
    Marketable securities consists of interest bearing securities with original
maturities in excess of three months. At December 31, 1997, the fair market
value of temporary investments, classified as "available for sale securities",
approximated cost, thus no unrealized holding gains or losses were reported in
the accompanying balance sheets. During fiscal year 1997, the Company realized
gains from the sale of securities of approximately $48,000.
 
    PROPERTY AND EQUIPMENT
 
    Property and equipment are carried at cost. Depreciation and amortization of
property and equipment are computed using the straight-line method over the
following estimated useful lives:
 
<TABLE>
<S>                                                         <C>
Operating equipment.......................................      5-25 years
Leasehold improvements....................................   Life of lease
Computer equipment........................................       3-7 years
Furniture and fixtures....................................       5-7 years
</TABLE>
 
    Operating equipment includes assets financed under capital lease obligations
of $6,218,000 and $15,921,000 at December 31, 1996 and 1997, respectively.
Accumulated amortization related to assets financed under capital leases was
$391,000 and $2,123,000 at December 31, 1996 and 1997, respectively.
 
    In addition, operating equipment includes seven Indefeasible Rights of Use
(IRU) in cable systems amounting to $110,000 and $2,303,000 and four ownership
interests in an international cable amounting to $148,000 and $1,534,000 at
December 31, 1996 and 1997, respectively. These assets are amortized over the
life of the agreements of 14 to 25 years (see Note 5).
 
    Replacements and betterments, renewals and extraordinary repairs that extend
the life of the asset are capitalized; other repairs and maintenance are
expensed. The cost and accumulated depreciation applicable to assets sold or
retired are removed from the accounts and the gain or loss on disposition is
recognized in other income or expense.
 
    DEPOSITS AND OTHER ASSETS
 
    Deposits represent payments made to long distance providers to secure lower
rates. These deposits are refunded or applied against future services. Other
assets at December 31, 1996 represent initial public offering expenses, which
were subsequently charged to additional paid in capital during 1997 at the time
of the initial public offering.

                               DECEMBER 31, 1997
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    The two largest customers represent approximately 16 percent, 26 percent and
17 percent of revenues during the years ended December 31, 1995, 1996 and 1997,
respectively. During 1995 and 1996, only sales to Cherry Communications exceeded
10 percent of total sales. For the year ended December 31, 1997, only one
customer equaled 10 percent of consolidated sales.
 
    The Company performs ongoing credit evaluations of its customers. The
Company analyzes daily traffic patterns and concludes whether or not the
customer's credit status justifies the traffic volume. If the customer is deemed
to carry too large a volume in relation to its credit history, the traffic
received by the Company's switch is reduced to prevent further build up of the
receivable from this customer. The Company's allowance for doubtful accounts is
based on current market conditions.
 
    Purchases from the four largest vendors for the years ended December 31,
1995 and 1996 amounted to 57 percent and 45 percent of total purchases,
respectively. Purchases from the four largest vendors for the year ended
December 31, 1997 amounted to 36 percent of total purchases.
 
    Included in the Company's balance sheets at December 31, 1996 and 1997 are
approximately $179,000 and $6,367,000 of equipment which is located in foreign
countries.
 
    USE OF ESTIMATES
 
    The preparation of consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the consolidated
financial statements and the reported amounts of revenues and expenses during
the reporting period. Actual results could differ from those estimates.
 
    RECENTLY ISSUED ACCOUNTING STANDARDS
 
    In February 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 128, "Earnings Per
Share". The statement replaces primary EPS with basic EPS, which is computed by
dividing reported earnings available to common stockholders by weighted average
shares outstanding. The provision requires the calculation of diluted EPS. The
Company adopted this statement in 1997 and all prior year earnings per share
amounts have been recalculated based on the provisions of SFAS No. 128.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
 
    TRANSLATION OF FOREIGN CURRENCY
 
    Management determined that the functional currency of its foreign
subsidiaries is still the U.S. dollar. Thus all foreign translation gains or
losses are reflected in the results of operations in other income (expense).
 
    The foreign subsidiary balance sheets are translated into U.S. dollars using
the year-end exchange rates except for prepayments, property, other long-term
assets, and stockholders' equity accounts, which are translated at rates in
effect when these balances were originally recorded. Revenues and expenses are
translated at average rates during the year except for depreciation and
amortization, which are translated at historical rates.
 
3. ACCRUED EXPENSES
 
    Accrued expenses at December 31, 1996 and 1997 consist of the following:

4. LINES OF CREDIT
 
    BANK LINE OF CREDIT
 
    Effective as of September 30, 1997, the Company executed an agreement with
Sanwa Bank, California for a $25 million line of credit, which expires on July
1, 1999. The facility has certain financial and non-financial covenants that
include, among other restrictions, the maintenance of minimum levels of tangible
net worth. Borrowings on the facility are limited to 75 percent of eligible
accounts receivable and are secured by substantially all of the assets of the
Company. The credit facility provides for borrowings at an interest rate based
upon the bank's cost of funds plus 1.75 percent (7.47 percent at December 31,
1997). The Company plans to use the credit facility to support letters of credit
and for working capital or other general corporate purposes. At December 31,
1997, no amounts were outstanding, however the Company's availability under this
credit facility was reduced to $20.1 million due to $4.9 million in letters of
credit which were outstanding at December 31, 1997.
 
    The weighted average interest rate on short term debt during the years ended
December 31, 1995, 1996 and 1997 was 10.21 percent, 9.68 percent and 9.12
percent, respectively.
 
    LINES OF CREDIT WITH STOCKHOLDER
 
    At December 31, 1996 and 1997, the Company's revolving lines of credit with
the founder and chief executive officer of the Company totaled $1,448,000. The
debt matures on March 30, 1998 with interest

6. COMMITMENTS AND CONTINGENCIES (CONTINUED)
    The Company has entered into six fixed asset purchase agreements. These
commitments are to purchase IRU's, switches, and leasehold improvements for
switch sites. The total commitment approximates $63 million. The Company plans
to finance the majority of these costs through capital lease arrangements.
 
    LEGAL MATTERS
 
    The Company is subject to litigation from time to time in the normal course
of business. Although it is not possible to predict the outcome of such
litigation, based on the facts known to the Company and after consultation with
counsel, management believes that such litigation will not have a material
adverse effect on its financial position or results of operations.
 
    On September 4, 1997, prior to the merger between LDS and the Company, LDS
entered into a settlement agreement with the Consumer Services Division of the
California Public Utilities Commission (PUC). The agreement settles the alleged
unauthorized switching of long-distance customers to LDS between the years 1995
and 1996. It includes a payment of $760,000 to the PUC for restitution to
affected customers as defined in the agreement. Additionally, LDS agreed to a
voluntary revocation of its operating authority in the State of California.
Under the agreement, service to all California customers has to be terminated
within 120 days after approval of the agreement by the PUC. On November 19,
1997, the PUC approved the agreement along with a transfer of control to STAR.
 
    On November 15, 1997, LDS settled a civil suit with the District Attorney of
Monterey, California for a monetary payment of $700,000 and various non-monetary
concessions as defined in the agreement. This suit was of the same nature as the
above action of the PUC and covers complaints from the years 1994 through 1997.
 
    LETTERS OF CREDIT
 
    At December 31, 1997, the Company has nine standby letters of credit
outstanding, which expire between January 20, 1998 and December 19, 1998. These
letters of credit, all of which are secured by the bank line of credit, total
$4,900,000.
 
7. RELATED PARTY TRANSACTIONS
 
    The founder and chief executive officer of the Company owns Star Aero
Services, Inc. (Star Aero). Star Aero's principal assets represent airplanes
which it provides to the Company for business travel on an as needed basis. In
return, the Company pays for costs related to the airplanes. Star Aero
reimburses the Company for certain costs relating to the maintenance of the
planes. For the years ended December 31, 1995, 1996 and 1997, the Company paid
$144,000, $68,000 and $171,000, respectively, in costs related to the use of
Star Aero services. As of December 31, 1995 and 1996, the Company had
receivables from Star Aero of $50,000 and $115,000, respectively. The Company
had no receivables from Star Aero at December 31, 1997.
 
    During 1997, the Company provided a short-term loan to the chief executive
officer for $8,000,000. The loan carried interest of 7 percent per annum, was
secured by $30,000,000 of the stockholder's stock in the Company, and was repaid
in seven days.

certain non-operating entities owned by LDS' shareholders and majority ownership
in an affiliated telephone retailer controlled by LDS. The accompanying
consolidated financial statements have been restated to include the financial
position and results of operations of LDS for all periods presented.

9. INCOME TAXES
 
    Through December 31, 1995, the Company had elected to be taxed as an
S-Corporation for both federal and state income tax purposes. While the election
was in effect, all taxable income, deductions,

9. INCOME TAXES (CONTINUED)
losses and credits of the Company were included in the tax returns of the
shareholders. Accordingly, for federal income tax purposes, no tax benefit,
liability or provision has been reflected in the accompanying historical
consolidated financial statements for the year ended December 31, 1995. For
state tax purposes, an S-Corporation is subject to a 1.5 percent tax on taxable
income, with a minimum tax of approximately $1,000 annually. Effective January
1, 1996, the Company terminated its S-Corporation election and is now taxable as
a C-Corporation.
 
    In addition, the results of operations and provision for income taxes for
LDS through November 30, 1997 reflects LDS' status as an S-Corporation. The
unaudited pro-forma income taxes, pro-forma net income (loss), and pro-forma
earnings per share information reflected in the consolidated statements of
operations assumes that both STAR and LDS were taxed as C-Corporations for all
periods presented.
 
    The Company accounts for income taxes in accordance with SFAS No. 109,
"Accounting for Income Taxes," under which deferred assets and liabilities are
provided on differences between financial reporting and taxable income using
enacted tax rates. Deferred income tax expenses or credits are based on the
changes in deferred income tax assets or liabilities from period to period.
Under SFAS No. 109, deferred tax assets may be recognized for temporary
differences that will result in deductible amounts in future periods. A
valuation allowance is recognized if, on the weight of available evidence, it is
more likely than not that some portion or all of the deferred tax asset will not
be realized.
 
    The Company has recorded a net deferred tax asset of $3,699,000 at December
31, 1997. Realization is dependent on generating sufficient taxable income in
the future. Although realization is not assured, management believes it is more
likely than not that the net deferred tax asset recorded will be realized.
 
    The components of the net deferred tax assets at December 31, 1996 and 1997
are as follows:

10. STOCK OPTIONS
 
    On January 22, 1996, the Company adopted the 1996 Stock Incentive Plan (the
"Plan"). The Plan, which was amended on March 31, 1996, provides for the
granting of stock options to purchase up to 1,476,000 shares of common stock and
terminates January 22, 2006. Options granted become exercisable at a rate of not
less than 20 percent per year for five years.
 
    During 1996, the Company entered into three separate stock option agreements
outside the Plan. The first agreement, dated March 1, 1996, provided for 410,000
non-incentive stock options exercisable immediately. The options were
exercisable at fair market value at the date of issuance, which was $0.98 per
share, to expire in 10 years. The second stock option agreement was entered into
on May 1, 1996 for an

additional 410,000 shares to also be issued at $0.98 per share. Of these options
half vested on March 1, 1997 and half expired. On May 15, 1996, the Company
granted 205,000 options, valued at $1.46 per share at the date of issuance to a
director. Of these options 34 percent were exercisable immediately. The
remaining options are exercisable equally on May 15, 1997 and 1998.
 
    At December 31, 1996 and 1997, 1,025,000 and 820,000 options, respectively,
issued outside a plan were outstanding.
 
    On September 23, 1996, the Company adopted the 1996 Supplemental Stock
Option Plan. This plan which expires on August 31, 2006, replaces the Plan and
has essentially the same features. The Company can issue options or other rights
to purchase up to 2,050,000 shares of stock which expire up to 10 years after
the date of grant, except for incentive options issued to a holder of more than
10 percent of the common stock outstanding, which expire five years after the
date of grant.
 
    In December 1996, the Company issued 174,000 options at $4.00 per share. The
Board of Directors determined the market value of the December options to be
$4.68 per share. The Company is recognizing the difference between the market
value at the date of grant and the exercise price as compensation expense over
the vesting period.
 
    At December 31, 1996 and 1997, 2,358,000 and 1,873,000 options,
respectively, were outstanding under the aggregate of the 1996 Stock Incentive
Plan and the Supplemental Stock Option Plan.
 
    On May 14, 1996, the Company adopted the 1996 Outside Director Nonstatutory
Stock Option Plan (the "Director Plan"). The number of shares which may be
issued under this plan upon exercise of options may not exceed 410,000 shares.
The exercise price of an option is determined by the Board of Directors and may
not be less than 85 percent of the fair market value of the common stock at the
time of grant and has to be 110 percent of the fair market value of the common
stock at the time of grant if the option is granted to a holder of more than 10
percent of the common stock outstanding. At the discretion of the administrator,
the options vest at a rate of not less than 20 percent per year, which may
accelerate upon a change in control, as defined. The plan expires on May 14,
2006. At December 31, 1996 and 1997, 82,000 and 41,000 options, respectively,
were outstanding under the Director Plan.
 
    On January 30, 1997, the Board of Directors approved the 1997 Omnibus Stock
Incentive Plan (the "Omnibus Plan") to replace the existing 1996 supplemental
plan upon the effective date of the initial public offering. The plan provides
for awards to employees, outside directors and consultants in the form of
restricted shares, stock units, stock options and stock appreciation rights and
terminates on January 22, 2007. The maximum number of shares available for
issuance under this plan may not exceed 1,025,000 shares plus the number of
shares still unissued under the supplemental option plan. Options granted to any
one optionee may not exceed more than 1,025,000 common shares per year subject
to certain adjustments. Incentive stock options may not have a term of more than
10 years from the date of grant. At December 31, 1997, 763,000 options, were

    The Company has elected to adopt FASB No. 123 for disclosure purposes only
and applies Accounting Principle Board (APB) Opinion No. 25 and related
interpretations in accounting for its employee stock options. Approximately
$50,000 and $88,000 in compensation cost was recognized relating to consultant
options for the years ended December 31, 1996 and 1997, respectively. Had
compensation cost for stock options awarded under these plans been determined
based on the fair value at the dates of grant consistent with the methodology of
FASB No. 123, the Company's net income or loss and basic and diluted income or
loss per share for the years ended December 31, 1996 and 1997 would have
reflected the following pro-forma amounts:

    The fair value of each option grant is estimated on the date of grant using
the minimum value method of option pricing with the following assumptions used
for the grants; weighted average risk-free interest rate of 6.4 and 6.2 percent
and an expected life of ten years and six years for the years ended December 31,
1996 and 1997, respectively. Expected volatility for 1997 was 31.05 percent and
it is assumed that no dividends would be issued during the option term. Because
the Company did not have a stock option program prior to 1996, the resulting
pro-forma compensation cost may not be representative of that to be expected in
future years.

    During 1994, the Company issued 16,606,661 shares of stock to the Company's

    ACQUISITIONS
 
    In November 1997, the Company signed a merger agreement with United Digital
Network, Inc. ("UDN"). Under the terms of the agreement, as amended, UDN
stockholders will receive approximately 800,000 shares of STAR common stock. The
Company intends to account for the transaction as a pooling of interests. At
December 31, 1997, the Company has accounts receivable from UDN in the amount of
$721,000 and a note receivable of $2.5 million plus accrued interest of $28,000.
Both the accounts receivable and the note have been fully reserved at December
31, 1997. Subsequent to year end, the Company loaned an additional $2 million to
UDN.
 
    On March 10, 1998, the Company consummated a merger with T-One Corp.
("T-One") to be accounted for as a pooling of interests. In connection with this
merger, the Company issued 1,353,000 shares of its common stock for all
outstanding shares of T-One. The following unaudited pro forma data

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    Section 145 of the Delaware General Corporation Law authorizes a court to
award or a corporation's Board of Directors to grant indemnification to
directors and officers in terms sufficiently broad to permit such
indemnification under certain circumstances for liabilities (including
reimbursement for expenses incurred) arising under the Securities Act of 1933,
as amended (the "Securities Act"). Article VII, Section 6, of the Registrant's
Bylaws provides for mandatory indemnification of its directors and officers and
permissible indemnification of employees and other agents to the maximum extent
permitted by the Delaware General Corporation Law. The Registrant's Amended and
Restated Certificate of Incorporation provides that, pursuant to Delaware law,
its directors shall not be liable for monetary damages for breach of the
directors' fiduciary duty as directors to the Company and its stockholders. This
provision in the Amended and Restated Certificate of Incorporation does not
eliminate the directors' fiduciary duty, and in appropriate circumstances
equitable remedies such as injunctive or other forms of non-monetary relief will
remain available under Delaware law. In addition, each director will continue to
be subject to liability for breach of the director's duty of loyalty to the
Company for acts or omissions not in good faith or involving intentional
misconduct, for knowing violations of law, for actions leading to improper
personal benefit to the director, and for payment of dividends or approval of
stock repurchases or redemptions that are unlawful under Delaware law. The
provision also does not affect a director's responsibilities under any other
law, such as the federal securities laws or state or federal environmental laws.
The Registrant has entered or will enter into Indemnification Agreements with
its officers and directors that provide the Registrant's officers and directors
with further indemnification to the maximum extent permitted by the Delaware
General Corporation Law. Reference is made to Section 7 of the Underwriting
Agreement contained in Exhibit 1.1 hereto, indemnifying officers and directors
of the Registrant against certain liabilities.

        2.  On November 30, 1997, the Registrant issued 849,298 shares of Common

        4.  On February 23, 1996, the Registrant issued and sold 2,049,979

    Series A Preferred Stock to a group of twenty-two investors for an aggregate
    purchase price of $7,500,003.51.
 
        7.  Since inception from time to time, as of February 28, 1998, the
    Registrant has granted to employees, directors and consultants options to
    purchase an aggregate of approximately 4,798,000 shares of Common Stock
    pursuant to stock option agreements and the Registrant's stock option plans.
 
    The sales and issuances described above were deemed to be exempt from
registration under the Securities Act in reliance upon Section 4(2) thereof, as
transactions by an issuer not involving any public offering, or in reliance upon
the exemption from registration provided by Rule 701 promulgated under the
Securities Act. In addition, the recipients of securities in each such
transaction represented their intentions to acquire the securities for
investment only and not with a view to or for sale in connection with any
distribution thereof and appropriate legends were affixed to the share
certificates issued in such transactions. All recipients had adequate access,
through their relationships with the Registrant, to information about the
Registrant.

ITEM 17. UNDERTAKINGS
 
    The Registrant hereby undertakes to provide to the Underwriters at the
closing specified in the Underwriting Agreement, certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.
 
    Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the Delaware General Corporation Law, the Certificate of
Incorporation or the Bylaws of the Registrant, the Underwriting Agreement, 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 Securities Act, and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the Registrant of expenses incurred or paid by a director, officer,
or controlling person of the Registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered hereunder, 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 of whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.
 
    The Registrant hereby undertakes that:
 
        (1) For purposes of determining any liability under the Securities Act,
    the information omitted from the form of Prospectus filed as part of this
    Registration Statement in reliance upon Rule 430A
 
                                      II-5
<PAGE>
    and contained in a form of Prospectus filed by the Registrant pursuant to
    Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to
    be part of this Registration Statement as of the time it was declared
    effective.
 
        (2) For the purpose of determining any liability under the Securities
    Act, each post-effective amendment that contains a form of Prospectus shall
    be deemed to be a new Registration Statement relating to the securities
    offered therein, and the offering of such securities at that time shall be
    deemed to be the initial bona fide offering thereof.

                             AGREEMENT AND PLAN OF MERGER



     AGREEMENT AND PLAN OF MERGER dated as of November 19, 1997 (this
"Agreement"), by and among STAR Telecommunications, Inc., a Delaware corporation
(the "Acquiror"), IIWII Corp., a Delaware corporation and wholly-owned
subsidiary of the Acquiror ("Newco"), and United Digital Network, Inc., a
Delaware corporation (the "Company").


                                   R E C I T A L S:

     A.   The Boards of Directors of Newco, the Acquiror and the Company deem it
advisable and in the best interests of their respective stockholders to merge
Newco with and into the Company (the "Merger") upon the terms and conditions set
forth herein and in accordance with the General Corporation Law of the State of
Delaware (the "General Corporation Law") (the Company and Newco being
hereinafter sometimes referred to as the "Constituent Corporations" and the
Company, following the effectiveness of the Merger, being hereinafter sometimes
referred to as the "Surviving Corporation"); and

     B.   The Boards of Directors of the Acquiror, Newco and the Company have
approved the Merger upon the terms and subject to the conditions set forth
herein and, in the case of the Company, on the receipt of a "fairness opinion"
from its financial advisor in form, substance, and scope that is satisfactory to
the Board of Directors of the Company.


                                  A G R E E M E N T

     NOW, THEREFORE, in consideration of the mutual representations, warranties,
covenants, agreements and conditions contained herein, and in order to set forth
the terms and conditions of the Merger and the mode of carrying the same into
effect, the parties hereby agree as follows:


                                      ARTICLE I
                                      THE MERGER

     1.1       THE MERGER.  Upon the terms and conditions hereinafter set forth
and in accordance with the General Corporation Law, at the Effective Time, as
defined below, Newco shall be merged with and into the Company and thereupon the
separate existence of Newco shall cease, and the Company, as the Surviving
Corporation, shall continue to exist under and be governed by the General
Corporation Law.


                                          1

<PAGE>

     1.2       FILING.  Upon the satisfaction or waiver of the conditions set
forth in Section 7 hereof (other than the condition set forth in Section 7.1(b)
which may not be waived), Newco and the Company will cause a Certificate of
Merger, in substantially the form of EXHIBIT A attached hereto (the "Certificate
of Merger"), to be executed and filed with the Secretary of State of the State
of Delaware as provided in Section 251 of the General Corporation Law.

     1.3       EFFECTIVE TIME OF THE MERGER.  The Merger shall become effective
immediately upon the filing, in accordance with Section 251 of the General
Corporation Law, of the Certificate of Merger with the Secretary of State of the
State of Delaware in accordance with Section 251.  The date and time of such
filing is herein sometimes referred to as the "Effective Time."

     1.4       CERTIFICATE OF INCORPORATION AND BY-LAWS.  Upon the effectiveness
of the Merger, the Certificate of Incorporation of Newco shall be the
certificate of incorporation of the Surviving Corporation and the By-Laws of
Newco as in effect on the date hereof shall be the By-Laws of the Surviving
Corporation.

     1.5       DIRECTORS AND OFFICERS.  The persons who are directors of Newco
immediately prior to the Effective Time and the officers of the Company shall,
after the Effective Time and in accordance with the Certificate of Merger, serve
as the directors and officers, respectively, of the Surviving Corporation, in
each case such directors and officers to serve until their successors have been
duly elected and qualified in accordance with the Certificate of Incorporation
and By-Laws of the Surviving Corporation.

     1.6       WARRANTS AND OPTIONS.  On the Effective Time, the Acquiror shall
assume the duties and obligations of the Company, and the Acquiror shall be
vested with the powers, rights and privileges of the Company, under (a) the
warrants of the Company that remain outstanding at the Effective Time (the
"Warrants") and (b) the options of the Company that remain outstanding at the
Effective Time (the "Options"), as such warrants and options are listed on
Schedule 5.3.  As of the Effective Time, the Acquiror shall have reserved for
issuance and continue to maintain sufficient shares of Acquiror Common Stock, as
defined below, to issue the required shares of Acquiror Common Stock pursuant to
the exercise of Warrants and Options after the Effective Time, subject to
appropriate adjustment in the exercise price thereof, based on the Exchange
Ratio, as defined below.


                                     ARTICLE II
                           CONVERSION OF AND SURRENDER AND
                               PAYMENT FOR COMMON STOCK

     2.1       CONVERSION.  At the Effective Time, by virtue of the Merger and
without any action on the part of the holders thereof:

               (a)  Each of the issued and outstanding shares of the Common
Stock, $.01 par value, of the Company ("Common Stock"), other than
(i) Dissenting Stock, as defined below,

                                          2
<PAGE>

or (ii) shares of Common Stock held in the treasury of the Company, shall be
automatically converted into the right to receive consideration per share (the
"Merger Consideration") consisting of that portion of a share (the "Exchange
Ratio") of the Acquiror's common stock, $0.001 per share ("Acquiror Common
Stock"), determined by dividing $2.75 by the average closing price of
Acquiror's Common Stock on the Nasdaq National Market for the five (5) trading
days prior to the Effective Time (the "Average Price"), provided that, if the
Average Price  is equal to or greater than $32.73, then the Exchange Ratio shall
be determined by dividing $3.00 by the Average Price, provided, further, that,
if the Average Price is less than or equal to $26.78, then the Exchange Ratio
shall be determined by dividing $2.50 by the Average Price.  The Exchange Ratio
shall be adjusted as may be necessary and appropriate to reflect any and all
stock splits, reverse stock splits, reclassifications and similar capital events
that affect Acquiror Common Stock.

               (b)  Each issued and outstanding share of the Common Stock of
Newco shall be converted into approximately Seven Thousand Five Hundred
Sixty-Four (7,564) validly issued, fully paid and non-assessable shares of
common stock, $.01 par value (the "New Common Stock"), of the Surviving
Corporation.

               (c)  All shares of Common Stock which are held by the Company as
treasury shares shall be canceled and retired and cease to exist, without any
conversion thereof or payment with respect thereto.

               (d)  No fraction of a share of Acquiror Common Stock will be
issued in the Merger, but, in lieu thereof, each holder of Common Stock who
would otherwise be entitled to a fraction of a share of Acquiror Common Stock
(after aggregating all fractional shares of Acquiror Common Stock to be received
by such holder) will be entitled to receive from the Acquiror an amount of cash
(rounded to the nearest whole US $0.01) equal to the product of (i) such
fraction of a share multiplied by (ii) the Average Price.

     Notwithstanding any provision of this Agreement to the contrary, shares of
the Common Stock with respect to which appraisal rights have been demanded and
perfected in accordance with Section 262(d) of the General Corporation Law (the
"Dissenting Stock") shall not be converted into the right to receive the Merger
Consideration at or after the Effective Time, and the holder thereof shall be
entitled only to such rights as are granted by the General Corporation Law.
Notwithstanding the preceding sentence, if any holder of shares of Common Stock
who demands appraisal of such shares under the General Corporation Law shall
effectively withdraw his demand for such appraisal (in accordance with
Section 262(k) of the General Corporation Law) or becomes ineligible for such
appraisal (through failure to perfect or otherwise) then, as of the Effective
Time or the occurrence of such event, whichever is the last to occur, such
holder's Dissenting Stock shall cease to be Dissenting Stock and shall be
converted into and represent the right to receive the Merger Consideration,
without interest thereon, as provided in this Section 2.1.  The Company shall
give Acquiror (i) prompt notice of any written demands for appraisal,
withdrawals of demands for appraisal and any other instrument served pursuant to
Section 262 of the General Corporation Law received by the Company and (ii) the
opportunity to

                                          3
<PAGE>

participate in all negotiations and proceedings with respect to demands for
appraisal under such Section.

     2.2       CLOSING OF TRANSFER BOOKS.  At the Effective Time, the stock
transfer books of the Company shall be closed, and no transfer of shares of
Common Stock of the Company shall thereafter be made.  If, after the Effective
Time, certificates previously representing shares of Common Stock are presented
to the Surviving Corporation or the Exchange Agent, as defined below, such
certificates shall be canceled and exchanged for the Merger Consideration as
provided in Section 2.1, subject to applicable law in the case of Dissenting
Stock.

     2.3       SURRENDER OF CERTIFICATES.  At least five days prior to the
mailing of the Proxy Statement, as defined below, Newco shall, subject to the
reasonable approval of the Company, designate an exchange agent (the "Exchange
Agent") to effect the exchange for Acquiror Common Stock of certificates that,
prior to the Effective Time, represented shares of Common Stock entitled to the
Merger Consideration.  As soon as practicable after the Effective Time, the
Exchange Agent shall send a notice and transmittal form to each holder of record
of Common Stock immediately prior to the Effective Time advising such holder of
the effectiveness of the Merger and the procedure for surrendering to the
Exchange Agent (who may appoint forwarding agents with the approval of Newco)
the certificate or certificates to be exchanged pursuant to the Merger.  Upon
the surrender for exchange of such a certificate, together with such letter of
transmittal duly completed and properly executed in accordance with instructions
thereto and such other documents as may be required pursuant to such
instructions, the holder shall receive the Merger Consideration.  After the
Effective Time, until so surrendered and exchanged, each certificate which
immediately prior to the Effective Time represented outstanding shares of the
Common Stock (other than Dissenting Stock) shall represent solely the right to
receive the Merger Consideration.


                                     ARTICLE III
                              CERTAIN EFFECTS OF MERGER

     3.1       EFFECT OF MERGER.  On and after the Effective Time, the Surviving
Corporation shall possess all the rights, privileges, powers and franchises, and
be subject to all the restrictions, disabilities and duties of each of the
Constituent Corporations; and all and singular rights, privileges, powers and
franchises of each of the Constituent Corporations, and all property, real,
personal and mixed, and all debts due to either of the Constituent Corporations
on whatever account, as well for stock subscriptions as all other things in
action or belonging to each of the Constituent Corporations, shall be vested in
the Surviving Corporation; and all property, rights, privileges, powers and
franchises, and all and every other interest shall be thereafter the property of
the Surviving Corporation as they were of the Constituent Corporations, and the
title to any real estate vested by deed or otherwise, in either of the
Constituent Corporations shall not revert or be in any way impaired; but all
rights of creditors and all liens upon any property of either of the Constituent
Corporations shall be preserved unimpaired, and all debts, liabilities and
duties of the Constituent Corporations shall thenceforth attach to and be the
sole responsibility of the

                                          4
<PAGE>

Surviving Corporation and may be enforced against the Surviving Corporation to
the same extent as if said debts, liabilities and duties had been incurred or
contracted by it.

     3.2       FURTHER ASSURANCES.  If at any time after the Effective Time the
Surviving Corporation shall consider or be advised that any further deeds,
assignments or assurances in law or any other acts are necessary, desirable or
proper to vest, perfect or confirm, of record or otherwise, in the Surviving
Corporation, the title to any property or right of the Constituent Corporations
acquired or to be acquired by reason of, or as a result of, the Merger, the
Constituent Corporations agree that the Surviving Corporation and its proper
officers and directors shall and will execute and deliver all such deeds,
assignments and assurances in law and do all acts necessary, desirable or proper
to vest, perfect or confirm title to such property or right in the Surviving
Corporation and otherwise to carry out the purposes of this Agreement, and that
the proper officers and directors of the Constituent Corporations and the proper
officers and directors of the Surviving Corporation are fully authorized in the
name of the Constituent Corporations or otherwise to take any and all such
action.


                                      ARTICLE IV
                        REPRESENTATIONS AND WARRANTIES OF THE

     Except as set forth in the disclosure schedules to be delivered to the
Acquiror by the Company (the "Disclosure Schedules") pursuant to Section 6.13,
the Company represents and warrants to the Acquiror and Newco as follows:

     5.1       CORPORATE ORGANIZATION.  Each of the Company and each of its
subsidiaries Advanced Management Services, Inc. CTN -- Custom Telecommunications
Network of Arizona, Inc. and United Digital Network of Texas, Inc. (formerly

Inc.) (each a "Subsidiary" and collectively, the "Subsidiaries"), is a
corporation duly organized, validly existing and in good standing under the laws
of its state of incorporation with all requisite corporate power and authority
to own, operate and lease its properties and to carry on its business as it is
now being conducted, and is qualified or licensed to do business and is in good
standing in each jurisdiction in which the failure to be so qualified or
licensed, in the aggregate, would have a material adverse effect on the
financial condition, operations or business of the Company and the Subsidiaries
taken as a whole (a "Company Material Adverse Effect").  The Certificates of
Incorporation and By-Laws of the Company and the Subsidiaries are in full force
and effect.  The Company is not in violation of or in default under any
provision of its Certificate of Incorporation or By-Laws.  The Subsidiaries are
the only subsidiaries, direct or indirect, of the Company.

     5.2       CAPITAL STOCK.  The authorized capital stock of the Company

are held in the Company's treasury. Except as set forth on SCHEDULE 5.2, all of
the outstanding shares of capital stock of each of the Subsidiaries are owned
beneficially and of record by the Company free and clear of all liens, charges,
encumbrances, options, rights of first refusal or limitations or agreements
regarding voting rights of any nature, other than the Proxy Agreement, as
defined below.  All of the outstanding shares of capital stock of the Company

SCHEDULE 5.3 or as contemplated by this Agreement, there is no outstanding
right, subscription, warrant, call, unsatisfied preemptive right, option or
other agreement or arrangement of any kind to purchase or otherwise to receive
from the Company or any Subsidiary any of the outstanding, authorized but
unissued, unauthorized or treasury shares of the capital stock or any other
equity security of the Company or any Subsidiary and there is no outstanding
security of any kind convertible into or exchangeable for such capital stock.

     5.4       AUTHORITY RELATIVE TO AGREEMENT.  The Company has full corporate
power and authority to execute and deliver this Agreement and to consummate the
Merger and the other transactions contemplated on its part hereby.  The
execution and delivery by the Company of this Agreement and the consummation of
the transactions contemplated on its part hereby have been duly authorized by
its Board of Directors, and (other than the approval and adoption of this
Agreement by the holders of a majority of the then outstanding shares of Common
Stock, as provided in Section 6.1 hereof, the filing and recordation of
appropriate merger documents as required by the General Corporation Law and the
receipt of a satisfactory fairness opinion from its financial advisor) no other
corporate proceedings on the part of the Company or its stockholders are
necessary to authorize the execution and delivery of this Agreement by the
Company or the consummation of the transactions contemplated on its part hereby.
In that regard, the Company hereby represents that its Board of Directors has
(i) determined that the Merger is fair to and in the best interests of the
Company's stockholders, (ii) approved the Merger and (iii) resolved to recommend
in the Proxy Statement adoption of this Agreement and authorization of the
Merger by the stockholders of the Company, such matters to be subject to the
fiduciary duties of such directors and to the receipt of a satisfactory fairness
opinion from its financial advisor. This Agreement has been duly executed and
delivered by the Company, and constitutes a legal, valid and binding obligation
of the Company, enforceable against the Company in accordance with its terms,
except to the extent that its enforceability may be limited by applicable
bankruptcy, insolvency, reorganization or other laws affecting the enforcement
of creditors' rights generally or by general equitable principles.

     5.5       NO VIOLATIONS OR CONSENTS.  Except as set forth on SCHEDULE 5.5,
the execution, delivery and performance of this Agreement by the Company and the
consummation by it of the transactions contemplated hereby will not (i) violate
or conflict with any provision of any charter or by-laws of the Company or any
Subsidiary, (ii) require the consent, waiver, approval, license or authorization
of or any filing by the Company or any Subsidiary with any third party or public
authority (other than (a) the filing of a premerger notification report under
the HSR Act, (b) in connection with or in compliance with the provisions of the
Exchange Act, the Securities Act, the General Corporation Law, the
Communications Act or the "takeover" or "blue sky" or "public utility" laws of
various states, and (c) and any other filings and approvals expressly
contemplated by this Agreement, including, without limitation, those with the
BCSC and the VSE), (iii) violate, conflict with or result in a breach of or the
acceleration of any obligation under, or constitute a default (or an event which
with notice or the lapse of time or both would become a default) under, or give
to others any right of termination, amendment, acceleration or cancellation of,
or result in the creation of a lien or other encumbrance on any property or
asset of the Company or any Subsidiary pursuant to any provision of any
indenture, mortgage, lien, lease, agreement, instrument, order, judgment or
decree to which the Company or any Subsidiary is subject or by which the Company
or any Subsidiary or any of their property or assets is bound, or (iv) violate
or conflict with any law, rule, regulation, permit, ordinance, regulation or
decree applicable to the Company or any Subsidiary or by which any property or
asset of either of them is bound or affected except, in each of the instances
set forth in items (i) through (iv) above, where failure to give such notice,
make such filings, or obtain such authorizations, consents or

                                          9
<PAGE>

approvals, or where such violations, conflicts, breaches or defaults, in the
aggregate, would not have a Company Material Adverse Effect.

     5.6       GOVERNMENTAL AUTHORIZATIONS AND REGULATIONS.  SCHEDULE 5.6 is a
true and complete list of all material governmental licenses, franchises,
permits and other authorizations ("Permits") held by the Company and/or the
Subsidiaries.  Such Permits are all governmental licenses, franchises, permits
and other authorizations necessary to the conduct of the business of the Company
and the Subsidiaries, except where the failure to hold such Permits, in the
aggregate, would not have a Company Material Adverse Effect.  Such Permits are
valid and in full force and effect and the Company knows of no threatened
suspension, cancellation or invalidation of any such Permit except where any
such action would not result in a Company Material Adverse Effect.  Neither the
Company nor any Subsidiary is in conflict with, or is in default or violation
of, any law, rule, regulation, order, judgment, Permit, ordinance, regulation or
decree applicable to the Company or any Subsidiary or by which any property or
asset of either of them is bound or affected, except where such conflicts,
defaults or violations, in the aggregate, would not have a Company Material
Adverse Effect.

     5.7       LITIGATION.  Except as may be disclosed in the PPM, as defined
below, or on SCHEDULE 5.7, there are no suits, arbitrations, actions or
proceedings, pending or, to the best of the Company's or any Subsidiary's
knowledge, threatened or, to the best of the Company's or any Subsidiary's
knowledge, investigations pending or threatened against the Company or any
Subsidiary or with respect to any property or asset of any of them before any
court, arbitrator, administrator or governmental or regulatory authority or body
which, in the aggregate, are likely to have a Company Material Adverse Effect.

     5.8       FINANCIAL STATEMENTS AND REPORTS; MATERIAL LIABILITIES.

               (a)  The Company has delivered to the Acquiror true and complete
copies of its Confidential Private Placement Memorandum dated October 28, 1997
(the "PPM")  As of the date thereof, the PPM did not contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading.  The financial
statements in the PPM were prepared in accordance with GAAP applied on a
consistent basis and (except as may be indicated therein or in the notes
thereto) present fairly the consolidated financial position, results of
operations and cash flows of the Company and its consolidated subsidiaries as of
the dates and for the periods indicated subject, in the case of un-audited
interim consolidated financial statements, to normal recurring year-end
adjustments and subject to the "going concern" opinion of the Company's
independent accountants.  (The audited consolidated balance sheet of the Company
and the Subsidiaries as of April 30, 1997 included in the PPM is hereinafter
called the "Company Balance Sheet," and April 30, 1997 is hereinafter called the
"Company Balance Sheet Date," and the Company's balance sheet for the three
month period ended July 31, 1997 included in the PPM is hereafter called the
"Interim Balance Sheet").

                                          10
<PAGE>

               (b)  Except as set forth on SCHEDULE 5.8(b), the Company and its
Subsidiaries, considered as a whole, have no material liabilities or obligations
(whether fixed, accrued, contingent or otherwise) that are not fully reflected
or provided for on, or disclosed in the notes to, the Company Balance Sheet or
the Company Interim Balance Sheet, except for (i) liabilities in the ordinary
course of business that could not be reasonably expected to have a Company
Material Adverse Effect or (ii) liabilities incurred in the ordinary course of
business that are not required by GAAP to be reflected thereon and which are not
material.

     5.9       ABSENCE OF CERTAIN CHANGES OR EVENTS.  Since the Company Balance
Sheet Date and except as disclosed on SCHEDULE 5.9, the business of the Company
and the Subsidiaries have been conducted in the ordinary course consistent with
past practice, and (i) there has not been any material adverse change in the
financial condition, results of operations, properties, or business of the
Company or any Subsidiary, nor, to the Company's knowledge, has there occurred
any event or development that could be reasonably foreseen to result in a
Company Material Adverse Effect.

     5.10      BENEFIT PLANS.  Except as disclosed on SCHEDULE 5.10, neither the
Company nor any Subsidiary has outstanding any employment agreement with any
officer or employee of the Company or any Subsidiary or any bonus, incentive
compensation, deferred compensation, profit sharing, stock option, stock bonus,
stock purchase, savings, severance, salary continuation, consulting, retirement
(including health and life insurance benefits provided after retirement) or
pension plan (including Company Employee Benefit Plans as defined in
Section 5.11 hereof) or arrangement with or for the benefit of any officer,
employee or other person, or for the benefit of any group of officers, employees
or other persons that provides for payment of more than $100,000 in annual
benefits.  Neither the Company nor any Subsidiary has made, or entered into any
agreement to make, any payment that becomes payable as a result of the
consummation of this transaction which would be treated as an "excess parachute
payment" as defined in Section 280G of the Internal Revenue Code of 1986, as
amended (the "IRC").  There are no such agreements, plans or other arrangements
entered into with or provided for any independent contractors with whom the
Company or any Subsidiary has a business relationship.

     5.11      ERISA.  Set forth on SCHEDULE 5.10 are all of the employee
benefit plans, as defined in Section 3(3) of the Employee Retirement Income
Security  Act of 1974, as amended ("ERISA"), but without regard to whether any
such plan is in fact subject to ERISA, that is sponsored, or is being maintained
or contributed to, by the Company or any Subsidiary that provides for payment of
more than $25,000 in annual benefits (the "Company Employee Benefit Plans").
None of the Company Employee Benefit Plans are "multiemployer plans" as defined
in Section 3(37) of ERISA.  The Company has furnished or made available or will
promptly after the date hereof make available to Newco and the Acquiror (a) a
true and complete copy of the plan document and summary plan description for
each Company Employee Benefit Plan, (b) a true and complete copy of the most
recently filed Form 5500 (including the related schedules) with respect to each
Company Employee Benefit Plan for which such form is required to be filed, (c) a
true and complete copy of any trust agreement, insurance contract or other
agreement or arrangement serving as source of funding any benefits payable under
any Company Employee Benefit Plan, and

                                          11
<PAGE>

(d) the most recently issued financial statement and actuarial report, if any,
for each Company Employee Benefit Plan.  No "prohibited transactions" (as such
term is defined in Section 4975 of the IRC, or in Part 4 of Subtitle B of
Title I of ERISA) have occurred with respect to any Company Employee Benefit
Plan that could result in the imposition of taxes or penalties that, in the
aggregate, could have a Company Material Adverse Effect.  With respect to each
of the Company Employee Benefit Plans that is intended to qualify for favorable
income tax treatment under Section 401(a) of the IRC, (i) the Internal Revenue
Service ("IRS") has issued a favorable determination letter with respect to such
plan; (ii) except as set forth on SCHEDULE 5.10, the Company has furnished Newco
and Acquiror with a copy of the determination letter most recently issued by the
IRS with respect to such plan and the application filed with the IRS for such
determination letter; and (iii) to the best knowledge of the Company, no event
has occurred from the date of each such favorable determination letter that
would adversely affect the tax-qualified status of the plan in question.  Each
Company Employee Benefit Plan has been administered in compliance with the
applicable requirements of ERISA and the IRC, and in compliance with all other
applicable provisions of law, except for such noncompliance, if any, that, in
the aggregate, would not have a Company Material Adverse Effect.  With respect
to each Company Employee Benefit Plan, neither the Company nor any Subsidiary
has incurred liabilities which, in the aggregate, could have a Company Material
Adverse Effect as a result of the violation of or the failure to comply with any
applicable provision of ERISA, the IRC, any other applicable provision of law,
or any provision of such plan.  None of the Company Employee Benefit Plans which
is an "employee pension benefit plan", as that term is defined in Section 3(2)
of ERISA (a "Company Employee Pension Benefit Plan"), has incurred an
"accumulated funding deficiency," within the meaning of Section 302 of ERISA or
Section 412 of the IRC which, in the aggregate, could have a Company Material
Adverse Effect.  Neither the Company nor any Subsidiary has failed to make any
contribution to, or to make any payment under, any Company Employee Benefit Plan
that it was required to make pursuant to the terms of the plan or pursuant to
applicable law in any amount which, in the aggregate, could have a Company
Material Adverse Effect.  To the best knowledge of the Company, no "reportable
events," with respect to which a notice must be filed with the Pension Benefit
Guaranty Corporation ("PBGC"), has occurred with respect to any Company Employee
Pension Benefit Plan subject to Title IV of the ERISA which events, in the
aggregate, could have a Company Material Adverse Effect.  No proceedings by the
PBGC to terminate any Company Employee Pension Benefit Plan pursuant to
Subtitle C of Title IV of ERISA have to the best of the Company's knowledge,
been instituted or threatened which, in the aggregate, could have a Company
Material Adverse Effect.  Except for any liabilities in an amount which, in the
aggregate, would not have a Company Material Adverse Effect, neither the Company
nor any Subsidiary (1) has incurred any liability to the PBGC in connection with
any Company Employee Pension Benefit Plan, including any liability under
Section 4069 of ERISA and any penalty imposed under Section 4071 of ERISA,
(2) has terminated any Company Employee Pension Benefit Plan, or ceased
operations at any facility or withdrawn from any Company Employee Pension
Benefit Plan, in a manner that could subject it to liability or any liens under
Section 4062, 4063, 4064 or 4068 of ERISA or (3) has any knowledge as to the
existence of any state of facts, or as to the occurrence of any transactions,
that might reasonably be anticipated to result in any liability of the Company
or any Subsidiary to the PBGC under any other provision of Title IV of ERISA.
There is no pending or, to the best knowledge of the

                                          12
<PAGE>

Company, threatened legal action, proceeding or investigation against or
involving any Company Employee Benefit Plan which could result in liabilities to
the Plan, the Company or any Subsidiary that, in the aggregate, could have a
Company Material Adverse Effect.  Except as disclosed on SCHEDULE 5.10, the
present value of accrued benefits of each Company Employee Benefit Plan that is
a defined benefit plan as defined in Section 3(35) of ERISA does not exceed the
value of the assets of such plan available to pay such benefits by an amount
that, in the aggregate for all such plans, could have a Company Material Adverse
Effect.  All representations made by the Company in this Section 5.11 are
likewise true with respect to each Subsidiary.

     5.12      ENVIRONMENTAL MATTERS.  "Company Real Properties" shall mean all
real property now or previously owned, operated or leased by the Company, any
Subsidiary or any predecessor-in-interest.  Except as set forth on SCHEDULE
5.12:  (i) the Company, each of the Subsidiaries, and to the best of the
Company's knowledge, each of the Company Real Properties is in compliance with,
and has no liability under any or all applicable Environmental Laws, except
where the failure to comply or such liability would not have a Company Material
Adverse Effect; (ii) none of the Company, any Subsidiary or any of the Company
Real Properties has been alleged in writing by any governmental agency or third
party to be in violation of, to be liable under, or to be subject to any
administrative or judicial proceeding pursuant to, any Environmental Law, the
violation of which would have a Company Material Adverse Effect; and (iii) to
the best knowledge of the Company and each Subsidiary, there are no facts or
circumstances which could reasonably form the basis for the assertion of any
claims against the Company or any Subsidiary relating to environmental matters
which, in the aggregate, would have a Company Material Adverse Effect.  As used
herein, Environmental Law means any federal, state, or local law, statute, rule
or regulation, or the common law governing or relating to the environment or to
occupational health and safety.

     5.13      REAL ESTATE LEASES.  SCHEDULE 5.13 sets forth a complete and
accurate list, a copy of which has been delivered to the Acquiror of (i) all
leases and subleases under which the Company or any Subsidiary is lessor or
lessee of any real property, together with all amendments, supplements,
nondisturbance agreements and other agreements pertaining thereto; (ii) all
material options held by the Company or any Subsidiary or contractual
obligations on the part of the Company or any Subsidiary to purchase or acquire
any interest in real property; and (iii) all options granted by the Company or
any Subsidiary or contractual obligations on the part of the Company or any
Subsidiary to sell or dispose of any material interest in real property (except
for sale-leaseback transactions) in each such instance in items (i) through
(iii) above, which provides for a payment of more than $25,000.  Such leases,
subleases and other agreements are in full force and constitute binding
obligations of the Company and, to the best of its knowledge, the other parties
thereto, and (i) there are no defaults thereunder by the Company or any
Subsidiary or, to the best of Company's knowledge, by any other party thereto;
and (ii) no event has occurred which (with notice, lapse of time or both or
occurrence of any other event) would constitute a default by the Company or any
Subsidiary or, to the best of the Company's knowledge, by any other party
thereto, other than defaults or events which, in the aggregate, would not have a
Company Material Adverse Effect.  The Company or a Subsidiary has good, valid
and insurable


                                          13
<PAGE>

leasehold title to all such leased property, free and clear of all encumbrances,
liens, charges or other restrictions of any kind or character, except for
Permitted Liens, as defined below.

     5.14      TITLE TO PROPERTIES; ABSENCE OF LIENS AND ENCUMBRANCES.
SCHEDULE 5.14 lists all real property owned by the Company or any Subsidiary as
of the date of this Agreement.  The Company and/or a Subsidiary has good, valid
and insurable title in fee simple to all of the real property listed on
SCHEDULE 5.14, free and clear of all encumbrances, liens, charges or other
restrictions of any character whatsoever, except for (i) statutory liens for
current taxes or assessments not due or delinquent or the validity of which is
being contested in good faith, (ii) mechanics, workers, repairmen's and other
similar liens arising or incurred in the ordinary course of business, (iii) such
other liens, imperfections in title, charges, easements, restrictions and other
encumbrances, if any, which in the aggregate do not have a Company Material
Adverse Effect, and (iv) except as set forth on SCHEDULE 5.14 (collectively
"Permitted Liens").  Except for leased assets, the Company and the Subsidiaries
have good and insurable title to all of their material tangible personal
property used in their businesses, including, without limitation, those
reflected in the Company Balance Sheet (other than assets disposed of in the
ordinary course of business since the Company Balance Sheet Date), free and

may represent a transaction more favorable to the Company's stockholders when
compared to the Merger and the Merger Consideration if, and only to the extent

confidentiality agreement on substantially the terms contained in Section 6.6 of
this Agreement, the Company shall notify the Acquiror as to the contents of

mortgage, lien, Contract, as defined below, order, judgment, ordinance,
regulation, decree or other agreement or instrument to which the Company or the

Neither the Company nor the Shareholder has, in connection with this Agreement,

provisions of any indenture, mortgage, lien, lease, agreement, Contract,
instrument, order, judgment, ordinance, regulation or decree to which the

knows of no threatened suspension, cancellation or invalidation of any such
Permit.  The Company is not in conflict with, or is in default or violation of,
any Permit applicable to the Company or by which any property or asset of the
Company is bound or affected, except where such conflicts, defaults or
violations, in the aggregate, would not have a Material Adverse Effect.

are no actions, proceedings, claims, complaints, grievances, investigations or
unfair labor practice complaints or grievances or investigations (collectively,
"Actions") pending or, to the best knowledge of the Company and the Shareholder,
threatened, against the Company or any of the assets or properties of the
Company or against the Shareholder before any court or governmental or
regulatory authority or body or arbitrator, which, if such Action were
determined adversely to the Company, would have, individually or in the
aggregate, a Material Adverse Effect, nor, to the best knowledge of the Company
and the Shareholder, is there any reasonable basis for any of the 


                                          10

foregoing.  There are no Actions pending or, to the best knowledge of the
Company and the Shareholder, threatened against the Company or the Shareholder

the accompanying statement of income and statement of cash flow for such fiscal

               (n)  incurrence of other liabilities involving an aggregate
amount in excess of One Hundred Fifty Thousand Dollars ($150,000) or more,
except in the ordinary course of business, or any material increase or change in
any assumptions underlying, or methods of calculating, any bad debt, contingency

               (o)  payment, discharge or satisfaction of any liabilities other

     5.10      BENEFIT PLANS.  Except as disclosed on Schedule 5.11, the Company
has no outstanding any written employment agreement with any officer or employee
of the Company or any bonus, incentive compensation, deferred compensation,
profit sharing, stock option, stock bonus, stock purchase, savings, severance,
salary continuation, consulting, retirement (including health and life insurance
benefits provided after retirement) or pension plan (including Company Employee
Benefit Plans, as defined below) or arrangement with or for the benefit of any
officer, employee or other person, or for the benefit of any group of officers,
employees or other persons, that provides for payment of more than $100,000 in
annual benefits.  The Company has not made, or entered into any agreement to
make, any payment that becomes payable as a result of the consummation of this
transaction which would be treated as an "excess parachute payment" as defined
in Section 280G of the Internal Revenue Code of 1986, as amended (the "IRC"). 
There are no such agreements, plans or other arrangements entered into with or
provided for any independent contractors with whom the Company has a business
relationship.

     5.11      ERISA.  Set forth on Schedule 5.11 are all of the employee
benefit plans, as defined in Section 3(3) of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA"), but without regard to whether any
such plan is in fact subject to ERISA, that is sponsored, or is being maintained
or contributed to, by the Company that provides for payment of



                                          13
<PAGE>


more than Seventy Five Thousand Dollars ($75,000) in annual benefits (the
"Company Employee Benefit Plans").  None of the Company Employee Benefit Plans
are "multiemployer plans" as defined in Section 3(37) of ERISA.  The Company has
furnished or made available or will promptly after the date hereof make
available to STAR (a) a true and complete copy of the plan document and summary
plan description, if any, for each Company Employee Benefit Plan, (b) a true and
complete copy of the most recently filed Form 5500 (including the related
schedules) with respect to each Company Employee Benefit Plan for which such
form is required to be filed, (c) a true and complete copy of any trust
agreement, insurance contract or other agreement or arrangement serving as
source of funding any benefits payable under any Company Employee Benefit Plan,
and (d) the most recently issued financial statement and actuarial report, if
any, for each Company Employee Benefit Plan.  No "prohibited transactions" (as
such term is defined in Section 4975 of the IRC, or in Part 4 of Subtitle B of
Title I of ERISA) have occurred with respect to any Company Employee Benefit
Plan that would result in the imposition of taxes or penalties that, in the
aggregate, would have a Material Adverse Effect.  With respect to each of the
Company Employee Benefit Plans that is intended to qualify for favorable income
tax treatment under Section 401(a) of the IRC, (i) the Internal Revenue Service
("IRS") has issued a favorable determination letter with respect to such plan;
(ii) except as set forth on Schedule 5.11, the Company has furnished or made
available to STAR a copy of the determination letter most recently issued by the
IRS with respect to such plan and the application filed with the IRS for such
determination letter; and (iii) to the best knowledge of the Company and the
Shareholder, no event has occurred from the date of each such favorable
determination letter that would materially adversely affect the tax-qualified
status of the plan in question.  Each Company Employee Benefit Plan has been
administered in compliance with the applicable requirements of ERISA and the
IRC, and in compliance with all other applicable provisions of law, except for
such noncompliance, if any, that, in the aggregate, would not have a Material
Adverse Effect.  With respect to each Company Employee Benefit Plan, the Company
has not incurred liabilities which, in the aggregate, would have a Material
Adverse Effect as a result of the violation of or the failure to comply with any
applicable provision of ERISA, the IRC, any other applicable provision of law,
or any provision of such plan.  None of the Company Employee Benefit Plans which
is an "employee pension benefit plan", as that term is defined in Section 3(2)
of ERISA (a "Company Employee Pension Benefit Plan"), has incurred an
"accumulated funding deficiency," within the meaning of Section 302 of ERISA or
Section 412 of the IRC which, in the aggregate, would have a Material Adverse
Effect.  The Company has not failed to make any contribution to, or to make any
payment under, any Company Employee Benefit Plan that it was required to make
pursuant to the terms of the plan or pursuant to applicable law in any amount
which, in the aggregate, would have a Material Adverse Effect.  To the best
knowledge of the Company, no "reportable events," with respect to which a notice
must be filed with the Pension Benefit Guaranty Corporation ("PBGC"), has
occurred with respect to any Company Employee Pension Benefit Plan subject to
Title IV of the ERISA which events, in the aggregate, would have a Material
Adverse Effect.  No proceedings by the PBGC to terminate any Company Employee
Pension Benefit Plan pursuant to Subtitle C of Title IV of ERISA have to the
best of the Company's knowledge, been instituted or threatened which, in the
aggregate, would have a Material Adverse Effect.  Except for any liabilities in
an amount which, in the aggregate, would not have a Material Adverse Effect, the
Company (1) has not incurred any liability to the PBGC in connection with any
Company 


                                          14

<PAGE>


Employee Pension Benefit Plan, including any liability under Section 4069 of
ERISA and any penalty imposed under Section 4071 of ERISA, (2) has not
terminated any Company Employee Pension Benefit Plan, or ceased operations at
any facility or withdrawn from any Company Employee Pension Benefit Plan, in a
manner that could subject it to liability or any liens under Section 4062, 4063,
4064 or 4068 of ERISA or (3) has no knowledge as to the existence of any state
of facts, or as to the occurrence of any transactions, that would result in any
liability of the Company to the PBGC under any other provision of Title IV of
ERISA.  There is no pending or, to the best knowledge of the Company or the
Shareholder, threatened legal action, proceeding or investigation against or
involving any Company Employee Benefit Plan which would result in liabilities to
the Plan, the Company that, in the aggregate, would have a Material Adverse
Effect.  Except as disclosed on Schedule 5.11, the present value of accrued
benefits of each Company Employee Benefit Plan that is a defined benefit plan as
defined in Section 3(35) of ERISA does not exceed the value of the assets of
such plan available to pay such benefits by an amount that, in the aggregate for
all such plans, would have a Material Adverse Effect.


     5.12      ENVIRONMENTAL MATTERS.    "Company Real Properties" shall mean
all real property now or previously owned, operated or leased by the Company. 
Except as set forth on Schedule 5.12:  (i) the Company and each of the Company
Real Properties is in compliance with, and has no liability under any or all
applicable Environmental Laws, except where the failure to comply or such
liability would not have a Material Adverse Effect; (ii) neither the Company nor
any of the Company Real Properties has been alleged in writing by any
governmental agency or third party to be in violation of, to be liable under, or
to be subject to any administrative or judicial proceeding pursuant to, any
Environmental Law, the violation of which would have a Material Adverse Effect;
and (iii) to the best knowledge of the Company and each Subsidiary, there are no
facts or circumstances which would result in any claims against the Company
relating to environmental matters which, in the aggregate, would have a Material
Adverse Effect.  As used herein, "Environmental Law" means any federal, state,
or local law, statute, rule or regulation, or the common law governing or
relating to the environment. 

     5.13      REAL ESTATE LEASES.  Schedule 5.13 sets forth a complete and
accurate list, a copy of which has been delivered to or made available to STAR
of (a) all leases and subleases under which the Company is lessor or lessee of
any real property, together with all amendments, supplements, nondisturbance
agreements and other agreements pertaining thereto; (b) all options held by the
Company or contractual obligations on the part of the Company to purchase or
acquire any material interest in real property; and (c) all options granted by
the Company or contractual obligations on the part of the Company to sell or
dispose of any material interest in real property (except for sale-leaseback
transactions) in each such instance in items (a) through (c) above, which
provides for an annual payment of more than Fifty Thousand Dollars ($50,000). 
Such leases, subleases and other agreements constitute binding obligations of
the Company and, to the best of its knowledge, the other parties thereto, and
(x) there are no defaults thereunder by the Company or, to the best of Company's
knowledge, by any other party thereto; and (y) no event has occurred which (with
notice, lapse of time or both or occurrence of any other event) would constitute
a default by the Company or, to the best of the Company's knowledge, by any 

                                          15


<PAGE>



other party thereto, other than defaults or events which, in the aggregate,
would not have a Material Adverse Effect.  The Company has good and valid
leasehold title to all such leased property, free and clear of all encumbrances,
liens, charges or other restrictions of any kind or character, except for
Permitted Liens, as defined below.

     5.14      TITLE TO PROPERTIES; ABSENCE OF LIENS AND ENCUMBRANCES.

the real property listed on Schedule 5.14, free and clear of all encumbrances,
liens, charges or other restrictions of any character whatsoever, except for
(a) statutory liens for taxes or assessments not due or delinquent or the
validity of which is being contested in good faith, (b) mechanics, workers,
repairmen's and other similar liens arising or incurred in the ordinary course
of business, (c) such other liens, imperfections in title, charges, easements,
restrictions and other encumbrances, if any, which in the aggregate do not have
a Material Adverse Effect, and (d) those items set forth on Schedule 5.14
(collectively, the "Permitted Liens").  Except for leased assets, the Company
has good and valid title to all of the material tangible personal property used
in its business, including, without limitation, those reflected in the balance

payroll, disability and all other taxes imposed on the Company or with respect
to any of their respective properties, or otherwise payable by them, including
interest and penalties, if any, in respect thereof (collectively, "Company
Taxes"), for the Company taxable period ended on December 31, 1996 and all
fiscal periods of the Company prior thereto, except such nonpayment, or failure
to make adequate provision, which, in the aggregate, would not have a Material
Adverse Effect.  Company Taxes paid and/or incurred from December 31, 1996 until
the Closing Date include only Company Taxes incurred in the ordinary course of
business determined in the same manner as in the taxable period ending on
December 31, 1996.  Except as disclosed on Schedule 5.15, the Company has timely
filed all income tax, excise tax, sales tax, use tax, gross receipts tax,
franchise tax, employment and payroll related tax, property tax, and all other
tax returns which the Company is required to file ("Tax Returns"), and have paid
or provided for all the amounts shown to be due thereon, except where such
failure to make such timely filings, in the aggregate, would not have a Material
Adverse Effect, and except for the nonpayment or nonprovision of such amounts
which, in the aggregate, would not have a Material Adverse Effect.  Except as
set forth on Schedule 5.15, (a) neither the Company has filed or entered into,
or is otherwise bound by, any election, consent or extension agreement that
extends any applicable statute of limitations with respect to taxable periods of
the Company, (b) the Company is not a party to any contractual obligation

Effect upon the Company.  Except as set forth on Schedule 5.15, no Action is

Common Stock or any other derivative security transaction, the purpose or effect
of which is to hedge or transfer to a third party all or any part of the risk of

               (f)  The Shareholder acknowledges and agrees that the

<PAGE>

the Company's representations or warranties, or any material breach by the
Company or the Shareholder of a covenant contained herein of which the Company
or the Shareholder has knowledge; and

               (l)  neither the Company nor the Shareholder shall enter into an

     6.2       ACCESS TO PROPERTIES AND RECORD; STAR NOTICE.  The Company shall

the Company, or with regard to any other transaction relating directly or

     6.4       INDEMNIFICATION BY STAR.

               (a)  STAR agrees to indemnify the Company, the Shareholder and
their respective officers, directors, employees, agents and representatives
(collectively, the "Shareholder Indemnitees") against, and hold such Shareholder
Indemnitees harmless from, any and all claims, obligations, costs, expenses
(including, without limitation, reasonable attorneys' fees and expenses),
damages, losses and liabilities (collectively, "Losses") arising out of the
breach of any representation, warranty, covenant or agreement of STAR herein. 
Notwithstanding the foregoing, STAR shall not be liable to any Shareholder
Indemnitee under this Section 6.4(a) until the aggregate of all such Losses
exceeds Two Hundred Fifty Thousand Dollars ($250,000) ("STAR's Threshold
Amount"), in which case STAR shall be required to indemnify the Shareholder
Indemnitees for the full amount of such Losses, including STAR's Threshold
Amount.  Notwithstanding the foregoing, no claim for indemnification under this
Section 6.4(a) may be made after the end of the Escrow Period.



                                          23

<PAGE>


               (b)  Each of the Shareholder Indemnitees agrees to give STAR
prompt written notice of any claim, assertion, event or proceeding by or in
respect of a third party of which it has knowledge concerning any Loss as to
which it may request indemnification hereunder.  STAR shall have the right to
direct, through counsel of its own choosing, the defense or settlement of any
such claim or proceeding (provided that STAR shall have first acknowledged its
indemnification obligations hereunder specifically in respect of such claim or
proceeding) at its own expense, which counsel shall be reasonably satisfactory
to the Shareholder Indemnitees.  If STAR elects to assume the defense of any
such claim or proceeding, the Shareholder Indemnitees may participate in such
defense, but in such case the expenses of the Shareholder Indemnitees incurred
in connection with such participation shall be paid by the Shareholder
Indemnitees.  The Shareholder Indemnitees shall reasonably cooperate with STAR
in the defense or settlement of any such claim, assertion, event or proceeding. 
If STAR elects to direct the defense of any such claim or proceeding, the
Shareholder Indemnitees shall not pay, or permit to be paid, any part of any
claim or demand arising from such asserted liability, unless STAR consents in
writing to such payment or unless STAR withdraws from the defense of such
asserted Loss, or unless a final judgment from which no appeal may be taken by
or on behalf of STAR is entered against such indemnified party for such Loss. 
STAR will not settle or compromise any claim subject to this Section 6.4(b)
without the prior consent of the affected Shareholder Indemnitees, such consent
not to be unreasonably withheld, provided that such consent shall not be
necessary if such settlement or compromise includes (i) the payment of monetary
damages by STAR on behalf of such Shareholder Indemnitees and (ii) the full
release of such Persons.  If STAR shall fail to defend, or if, after commencing
or undertaking any such defense, STAR fails to prosecute or withdraws from such
defense, the Shareholder Indemnitees shall have the right to undertake the
defense or settlement thereof at STAR's expense.

     6.5       INDEMNIFICATION BY THE SHAREHOLDER.

               (a)  The Shareholder agrees to indemnify STAR, and each of STAR's
respective officers, directors, employees, agents and representatives
(collectively, the "STAR Indemnitees"), against, and hold such STAR Indemnitees
harmless from any and all Losses of STAR arising out of the breach of any
representation, warranty, covenant or agreement of the Shareholder herein or (to
the extent that such breach occurs prior to the Closing) of the Company herein.
Notwithstanding the foregoing, the Shareholder shall not be liable to the STAR
Indemnitees under this Section 6.5(a) until the aggregate of all such Losses
exceeds Two Hundred Fifty Thousand Dollars ($250,000) (the "Shareholder's
Threshold Amount"), in which case the Shareholder shall be required to indemnify
the STAR Indemnitees for the full amount of such Losses, including the
Shareholder's Threshold Amount, provided that the Shareholder's Threshold Amount
shall not apply with respect to any Loss resulting from a breach of the
representations and warranties contained in Section 5.2.  Notwithstanding the
foregoing, no claim for indemnification under this Section 6.5(a) may be made
after the Escrow Period.

               (b)  Each of the STAR Indemnitees agrees to give the Shareholder
prompt written notice of any claim, assertion, event or proceeding by or in
respect of a third party of which it has knowledge concerning any Loss as to
which it may request indemnification 


                                          24

<PAGE>


hereunder.  The Shareholder shall have the right to direct, through counsel of
its own choosing, the defense or settlement of any such claim or proceeding
(provided that the Shareholder shall have first acknowledged its indemnification
obligations hereunder specifically in respect of such claim or proceeding) at
its own expense, which counsel shall be reasonably satisfactory to the STAR
Indemnitees.  If the Shareholder elects to assume the defense of any such claim
or proceeding, the STAR Indemnitees may participate in such defense, but in such
case the expenses of the STAR Indemnitees incurred in connection with such
participation shall be paid by the STAR Indemnitees.  The STAR Indemnitees shall
reasonably cooperate with the Shareholder in the defense or settlement of any
such claim, assertion, event or proceeding.  If the Shareholder elects to direct
the defense of any such claim or proceeding, the STAR Indemnitees shall not pay,
or permit to be paid, any part of any claim or demand arising from such asserted
Loss, unless the Shareholder consents in writing to such payment or unless the
Shareholder withdraws from the defense of such asserted Loss, or unless a final
judgment from which no appeal may be taken by or on behalf of the Shareholder is
entered against any STAR Indemnitee for such Loss.  The Shareholder will not
settle or compromise any claim subject to this Section 6.5(b) without the prior
consent of the affected STAR Indemnitees, such consent not to be unreasonably
withheld, provided that such consent shall not be necessary if such settlement
or compromise includes (i) the payment of monetary damages by the Shareholder on
behalf of such STAR Indemnitees and (ii) the full release of such Persons.  If
the Shareholder shall fail to defend, or if, after commencing or undertaking any
such defense, the Shareholder fails to prosecute or withdraws from such defense,
the STAR Indemnitees shall have the right to undertake the defense or settlement
thereof at the Shareholder's expense.

               (c)  Any Loss subject to indemnification pursuant to this
Section 6.5 shall be offset against any appropriate number of Escrow Shares
pursuant to the terms and conditions of the Escrow Agreement.

     6.6       CERTAIN LIMITATIONS OF INDEMNIFICATION.  Notwithstanding anything
contained in this Agreement to the contrary: 

               (a)  In no event shall the aggregate liability of the Shareholder
hereunder exceed the aggregate value of the Escrow Shares at the Closing Date
(with such value to be calculated as set forth in the Escrow Agreement).  In no
event shall any Indemnifying Party be liable to any Indemnified Party for
special, indirect or consequential damages or loss of profits.  No
indemnification shall be made hereunder in respect of any representation or
warranty of the Shareholder relating or the Company to or concerning, directly
or indirectly, any of the items in the Closing Balance Sheet.

               (b)  If any claim for indemnification hereunder is or may be the
subject of insurance or other right to indemnification or contribution from any
third party, the Indemnified Parties promptly shall notify each applicable
insurance carrier of any such claim and related Loss and tender defense thereof
to such insurance carrier, and shall notify each potential third party
indemnitor or contributor that may be liable for all or any portion of such
claim and related Loss. 


                                          25

<PAGE>


The Indemnified Parties shall cooperate with each such insurance carrier, and
shall pursue diligently all rights against and cooperate with each such third
party indemnitor or contributor.

               (c)  The indemnification obligations of the Shareholder on the
one hand under Section 6.4 and of STAR on the other under Section 6.5 shall
constitute the sole and exclusive remedies of STAR on the one hand and the
Shareholder on the other hand, for the recovery of money damages with respect to
the matters described in Sections 6.4 and 6.5.

               (d)  Any liability for indemnification under Section 6.4 or 6.5
shall be determined without duplication of recovery by reason of the state of
facts giving rise to such liability constituting a breach of more than one
representation, warranty, covenant or agreement.

               (e)  If any Indemnifying Party shall be liable for
indemnification under Section 6.4 or 6.5, then such Indemnifying Party shall be
subrogated to all rights of the Indemnified Party with respect to the claims to
which such indemnification relates.

               (f)  As used in this Section 6.6, "Indemnified Party" shall mean
the Shareholder Indemnitees or the STAR Indemnitees, as applicable.

     6.7       CONFIDENTIALITY.  

               (a)  Subject to applicable law, STAR will hold, and will cause
each of its affiliates, employees, officers, directors and other representatives
to hold, in strict confidence, and to not use to the detriment of the Company
any information or data concerning the Company furnished to them in connection
with the transactions contemplated by this Agreement; and if the transactions
contemplated by this Agreement are not consummated, such confidence shall be
maintained and STAR will return to the Company all such information and data as
the Company may request.  Notwithstanding the foregoing, a Person may disclose
such data and information (i) if compelled to disclose the same by judicial or
administrative process or by other requirements of law, (ii) in any action, suit
or proceeding brought by a party hereto in pursuit of its rights or in the
exercise of its remedies hereunder, (iii) if the same can be shown to have been
previously known by such Person, (iv) if the same hereafter is in the public
domain through no fault of such Person, or (v) if the same is later acquired by
such Person from another source and such Person is not aware that such source is
under an obligation to another party hereto to keep such data and information
confidential.

               (b)  Subject to applicable law, the Company will hold, and will
cause each of the its affiliates, employees, officers, directors and other
representatives to hold, in strict confidence, and to not use to the detriment
of STAR, any information or data concerning STAR furnished to them in connection
with the transactions contemplated by this Agreement, and if the transactions
contemplated by this Agreement are not consummated, such confidence shall be
maintained and the Company will return to STAR all such information and data as
STAR may request.  Notwithstanding the foregoing, a Person may disclose such
data and information (i) if compelled to disclose the same by judicial or
administrative process or by other requirements of 


                                          26
<PAGE>


law, (ii) in any action, suit or proceeding brought by a party hereto in pursuit
of its rights or in the exercise of its remedies hereunder, (iii) if the same
can be shown to have been previously known by such Person, (iv) if the same
hereafter is in the public domain through no fault of such Person, or (v) if the
same is later acquired by such Person from another source and such Person is not
aware that such source is under an obligation to another party hereto to keep
such data and information confidential.

     6.8       REASONABLE BEST EFFORTS.  Subject to the terms and conditions
hereof, each of the parties hereto agrees to use his or its reasonable best
efforts necessary (a) to take, or cause to be taken, all action and to do, or
cause to be done, all things necessary to satisfy the conditions set forth
herein as soon as practicable, (b) to have removed or rescinded any temporary,
preliminary or permanent injunction, including the injunctions or other orders
described in Section 7.1(a), and (c) to defend against any and all litigation. 
STAR and the Company each agree to take, or cause to be taken, all action, and
to do, or cause to be done, all things necessary or required by the United
States Federal Communications Commission (the "FCC") and applicable state
regulatory agencies and public utilities in connection with the transfer of any
licenses required hereunder, including without limitation, any license held by
the Company under Section 214 of the Communications Act of 1934, as amended (the
"Communications Act"), provided that neither party will be required to take any
action or to do anything in connection with the foregoing which would materially
impair STAR's ownership or operation of all or a material portion of the
business and assets of the Company or compel STAR to dispose of all or a
material portion of the business or assets of STAR.  No party hereto will take
any action for the purpose of delaying, impairing or impeding the receipt of any
required consent, authorization, order or approval or the making of any required
filing or registration.

     6.9       DELIVERY OF FINANCIAL STATEMENTS AND OTHER DOCUMENTS BY THE
               COMPANY.

and all SEC Filings made by STAR under the Securities Act or the Exchange Act

Shareholder contained herein are not true and correct.

     6.11      NON-COMPETITION.

following the Closing Date, the Shareholder will not, on his own behalf, on
behalf of any Person controlled by him or by acting as an officer, director,
employee, consultant or agent to any Person, solicit, call on or do business
with any U.S. based provider or carrier of long distance telecommunication
services.

               (b)  The Shareholder acknowledges that, due to his unique
knowledge and expertise in the area of long distance telecommunications, STAR
would not be reasonably and adequately compensated with monetary damages for a
breach of this Section 6.11.  As such, the Shareholder agrees that STAR shall be
entitled to seek injunctive relief for any breach or alleged breach of this
Section 6.11, in addition to any other remedy at law or in equity that may be
available to STAR.

     6.12      CERTAIN EVENTS.  STAR will promptly advise the Company and the
Shareholder in writing of any event or condition that would have a material
adverse effect on the ability of STAR to consummate the transactions
contemplated hereby, or of any material breach of STAR's representations or
warranties or any material breach of a covenant contained herein of which STAR
has knowledge.

     6.13      RESTRICTION ON TRANSFER OF SHARES.  Notwithstanding anything in
this Agreement to the contrary, from and after the Closing Date the Shareholder
will not sell, transfer or otherwise dispose of, offer to sell, transfer or
otherwise dispose of or take any other action that reduces the risk of the
Shareholder's ownership of or investment in any of the STAR Shares, until such
time as STAR has published financial results covering at least 30 days of
post-Closing combined operations of STAR and the Company.  Publication may,
without limitation, include a Form 10-Q or 8-K filing, the issuance of a
quarterly report or monthly earning report, or any other public issuance that
includes combined sales and net income for 30 days of post-Closing operations.

enforce specifically this Agreement and the terms and conditions hereof in any
action instituted in any court of the United States or any state having

discretion of the Company, be required to execute and deliver a reasonable
confidentiality agreement or similar nondisclosure document.  Neither STAR nor
the Company shall destroy any item referred to above in this Section 9.12
without first offering to the Shareholder the opportunity, at the Shareholder's
expense to obtain the same.

          SECOND: That the Board of Directors duly adopted resolutions 
proposing to amend and restate the Amended and Restated Certificate of

          "RESOLVED, that the Amended and Restated Certificate of 
Incorporation of this corporation be amended and restated in its entirety as

is to engage in any lawful act or activity for which corporations may be

<PAGE>

                                   ARTICLE IV

          The Corporation is authorized to issue two classes of stock to be 
designated common stock ("Common Stock") and preferred stock ("Preferred 
Stock"). The number of shares of Common Stock authorized to be issued is 
Fifty Million (50,000,000), par value $0.001 per share, and the number of 
Preferred Stock authorized to be issued is Five Million (5,000,000), par 
value $0.001 per share.

          The Preferred Stock may be issued from time to time in one or more 
series, without further stockholder approval. The Board of Directors is 
hereby authorized, in the resolution or resolutions adopted by the Board of 
Directors providing for the issue of any wholly unissued series of Preferred 
Stock, within the limitations and restrictions stated in this Second Amended 
and Restated Certificate of Incorporation (the "Restated Certificate"), to 
fix or alter the dividend rights, dividend rate, conversion rights, voting 
rights, rights and terms of redemption (including sinking fund provisions), 
the redemption price or prices, and the liquidation preferences of any wholly 
unissued series of Preferred Stock, and the number of shares constituting any 
such series and the designation thereof, or any of them, and to increase or 
decrease the number of shares of any series subsequent to the issue of shares 
of that series, but not below the number of shares of such series then 
outstanding. In case the number of shares of any series shall be so 
decreased, the shares constituting such decrease shall resume the status that 
they had prior to the adoption of the resolution originally fixing the number 
of shares of such series.

                                 ARTICLE V

          Except as otherwise provided in this Restated Certificate, in 
furtherance and not in limitation of the powers conferred by statute, the 
Board of Directors is expressly authorized to make, repeal, alter, amend and 
rescind any or all of the Bylaws of the Corporation.

                                ARTICLE VI

          The number of directors of the Corporation shall be fixed from time 
to time by a bylaw or amendment thereof duly adopted by the Board of 
Directors.

          The Board of Directors shall be and is divided into three classes, 
Class I, Class II and Class III. Such classes shall be as nearly equal in 
number of directors as possible. Each director shall serve for a term ending 
on the third annual meeting following the annual meeting at which such 
director was elected; provided, however, that the directors first elected to 
Class I shall serve for a term ending on the annual meeting next following 
the end of fiscal year 1997, the directors first elected to Class II shall 
serve for a term ending on the second annual meeting next following the end 
of fiscal year 1998, and the directors first elected to Class III shall serve 
for a term ending on the third annual meeting next following the end of 
fiscal year 1999. The foregoing notwithstanding, each director shall serve 
until his successor shall have been duly elected and qualified, unless he 
shall resign, become disqualified, disabled or shall otherwise be removed.

                                     2
<PAGE>

          At each annual election, directors chosen to succeed those whose 
terms then expire shall be of the same class as the directors they succeed, 
unless by reason of any intervening changes in the authorized number of 
directors, the Board shall designate one or more directorships whose term 
then expires as directorships of another class in order more nearly to 
achieve equality of number of directors among the classes.

          Notwithstanding the rule that the three classes shall be as nearly 
equal in number of directors as possible, in the event of any change in the 
authorized number of directors each director then continuing to serve as such 
shall nevertheless continue as a director of the class of which he is a 
member until the expiration of his current term, or his prior death, 
resignation or removal. If any newly created directorship may, consistently 
with the rule that the three classes shall be as nearly equal in number of 
directors as possible, be allocated to either class, the Board shall allocate 
it to that of the available class whose term of office is due to expire at the 
earliest date following such allocation.

                                ARTICLE VII

          Elections of directors need not be by written ballot unless the 
Bylaws of the Corporation shall so provide.

                                ARTICLE VIII

          Except as otherwise provided in this Restated Certificate, any 
action required or permitted to be taken by the stockholders of the 
Corporation must be effected at an annual or special meeting of the 
stockholders of the Corporation, and no action required to be taken or that 
may be taken at any annual or special meeting of the stockholders of the 
Corporation may be taken without a meeting except by the unanimous written 
consent of all stockholders entitled to vote on such action, and the power of 
stockholders to consent in writing to the taking of any action by less than 
unanimous consent of all such stockholders is specifically denied.

                                 ARTICLE IX

          A director of the Corporation shall not be personally liable to the 
Corporation or its stockholders for monetary damages for breach of fiduciary 
duty as a director, except for liability (i) for any breach of the director's 
duty of loyalty to the Corporation or its stockholders, (ii) for acts or 
omissions not in good faith or which involve intentional misconduct or a 
knowing violation of law, (iii) under Section 174 of the Delaware General 
Corporation Law, or (iv) for any transaction from which the director derived 
any improper personal benefit. If the Delaware General Corporation Law is 
amended after approval by the stockholders of this Article to authorize 
corporate action further eliminating or limiting the personal liability of 
directors then the liability of a director of the Corporation shall be 
eliminated or limited to the fullest extent permitted by the Delaware General 
Corporation Law as so amended.

          Any repeal or modification of the foregoing provisions of this 
Article IX by the stockholders of the Corporation shall not adversely affect 
any right or protection of a director of the Corporation existing at the time 
of such repeal or modification.

                                 ARTICLE X

          In addition to any vote of the holders of any class or series of 
the stock of this Corporation required by law or by this Restated 
Certificate, the affirmative vote of the holders of a majority of the voting 
power of all of the then outstanding shares of capital stock of the 
Corporation entitled to vote generally in the election of directors, voting 
together as a single class, shall be required to amend or repeal the 
provisions of ARTICLE I, ARTICLE II, and ARTICLE III of this Restated 
Certificate. Notwithstanding any other provision of this Certificate of 
Incorporation or any provision of law which might otherwise permit a lesser 
vote or no vote, but in addition to any vote of the holders of any class or 
series of the stock of this Corporation required by law or by this Restated 
Certificate, the affirmative vote of the holders of at least seventy-five 
percent (75%) of the voting power of all of the then outstanding shares of 
the capital stock of the Corporation entitled to vote generally in the 
election of directors, voting together as a single class, shall be required 
to amend or repeal any provision of this Restated Certificate not specified 
in the preceding sentence.

                               *  *  *  *

          THIRD: The foregoing Second Amended and Restated Certificate of 
Incorporation has been duly adopted by the Corporation's Board of Directors 
in accordance with the applicable provisions of Section 245 of the General 
Corporation Law of the State of Delaware.

                                   DIRECTORS

     SECTION 1. The number of directors shall be fixed from time to time 
exclusively by the Board of Directors pursuant to a resolution adopted by a 
majority of the total number of authorized directors (whether or not there 
exist any vacancies in previously authorized directorships at the time any 
such resolution is presented to the Board for adoption). Directors shall be 
divided into three classes, as nearly equal in number as reasonably possible, 
with the term of office of the first class to expire at the 1997 annual 
meeting of stockholders, the term of office of the second class to expire at 
the 1998 annual meeting of stockholders and the term of office of the third 
class to expire at the 1999 annual meeting of stockholders. At each annual 
meeting of stockholders following such initial classification and election, 
directors elected to succeed those directors whose terms expire shall be 
elected for a term of office to expire at the third succeeding annual meeting 
of stockholders after their election. All directors shall hold office until 
the expiration of term for which elected, and until their respective 
successors are elected and qualified, except in the case of the death, 
resignation or removal of any director. Directors need not be stockholders.

     SECTION 2. Vacancies and newly created directorships resulting from any 
increase in the authorized number of directors may be filled by a majority of 
the directors then in office, though less than a quorum, or by a sole 
remaining director, and the directors so chosen shall hold office until the 
next annual election and until their successors are duly elected and shall 
qualify, unless sooner displaced. If there are no directors in office, then 
an election of directors may be held in the manner provided by statute.

     SECTION 3. The business of the corporation shall be managed by or under 
the direction of its board of directors, which may exercise all such powers 
of the corporation and do all such lawful acts and things as are not by 
statute or by the certificate of incorporation or by these bylaws directed or 
required to be exercised or done by the stockholders.

                       MEETINGS OF THE BOARD OF DIRECTORS

     SECTION 4. The Board of Directors of the corporation may hold meetings, 
both regular and special, either within or without the State of Delaware.

     SECTION 5. The first meeting of each newly elected Board of Directors 
shall be held at such time and place as shall be fixed by the vote of the 
stockholders at the annual meeting and no notice of such meeting shall be 
necessary to the newly elected directors in order legally to constitute the 
meeting, provided a quorum shall be present. In the even of the failure of 
the stockholders to fix the time or place of such first meeting of the newly 
elected Board of Directors, or in the event such meeting is not held at the 
time and place so fixed by the stockholders, the meeting may be held at such 
time and place as shall be specified in a notice given as hereinafter 
provided for special meetings of the Board of Directors, or as shlal be 
specified in a written waiver signed by all of the directors.

the president on ten (10) days' notice to each director by mail or 
forty-eight (48) hours notice to each director either personally or by 
telephone, telegram or facsimile; special meetings shall be called by the 
president or secretary in like manner and on like notice on the written 
request of two (2) directors unless the board consists of only one director, 
in which case special meetings shall be called by the president or secretary 
in like manner and on like notice on the written request of the sole director.

     SECTION 8. At all meetings of the board a majority of the directors 
shall constitute a quorum for the transaction of business and the act of a 
majority of the directors present at any meeting at which there is a quorum 
shall be the act of the Board of Directors, except as may be otherwise 
specifically provided by statute or by the certificate of incorporation. If a 
quorum shall not be present at any meeting of the Board of Directors, the 
directors present thereat may adjourn the meeting from time to time, without 
notice other than announcement at the meeting, until a quorum shall be 
present.

     SECTION 9. Unless otherwise restricted by the certificate of 
incorporation of these bylaws, any action required or permitted to be taken 
at any meeting of the Board of Directors or of any committe thereof may be 
taken without a meeting, if all members of the board or committee, as the 
case may be, consent thereto in writing, and the writing or writings are 
filed with the minutes of proceedings of the board or committee.

     SECTION 10. Unless otherwise restricted by the certificate of 
incorporation or these bylaws, members of the Board of Directors, or any 
committee designated by the Board of Directors, may participate in a meeting 
of the Board of Directors, or any committee, by means of conference telephone 
or similar communications equipment by means of which all persons 
participating in the meeting can hear each other, and such participation in a 
meeting shall constitute presence in person at the meeting.

                           COMMITTEES OF DIRECTORS

     SECTION 11. The Board of Directors may, by resolution passed by a 
majority of the whole board, designate one (1) or more committees, each 
committee to consist of one (1) or more of the directors of the corporation. 
The board may designate one (1) or more directors as alternate members of 
any committee, who may replace any absent or disqualified member at any 
meeting of the committee.

     In the absence of disqualification of a member of a committee, the 
member or members thereof present at any meeting and not disqualified from 
voting, whether or not he or she or they constitute a quorum, may unanimously 
appoint another member of the Board of Directors to act at the meeting in the 
place of any such absent or disqualified member.

                                       4
<PAGE>

     Any such committee, to the extent provided in the resolution of the 
Board of Directors, shall have and may exercise all the powers and authority 
of the Board of Directors in the management of the business and affairs of 
the corporation, and may authorize the seal of the corporation to be affixed 
to all papers that may require it; but no such committee shall have the power 
or authority in reference to amending the certificate of incorporation, 
adopting an agreement of merger or consolidation, recommending to the 
stockholders the sale, lease or exchange of all or substantially all of the 
corporation's property and assets, recommending to the stockholders a 
dissolution of the corporation or a revocation of a dissolution, or amending 
the bylaws of the corporation; and, unless the resolution or the certificate 
of incorporation expressly so provide, no such committee shall have the power 
or authority to declare a dividend or to authorize the issuance of stock. 
Such committee or committees shall have such name or names as may be 
determined from time to time by resolution adopted by the Board of Directors.

     SECTION 12. Each committee shall keep regular minutes of its meetings 
and report the same to the Board of Directors when required.

                           COMPENSATION OF DIRECTORS

     SECTION 13. Unless otherwise restricted by the certificate of 
incorporation or these bylaws, the Board of Directors shall have the 
authority to fix the compensation of directors. The directors may be paid 
their expenses, if any, of attendance at each meeting of the Board of 
Directors and may be paid a fixed sum for attendance at each meeting of the 
Board of Directors or a stated salary as director. No such payment shall 
preclude any director from serving the corporation in any other capacity and 
receiving compensation therefor. Members of special or standing committees 
may be allowed like compensation for attending committee meetings.

                             REMOVAL OF DIRECTORS

     SECTION 14. Unless otherwise restricted by the certificate of 
incorporation or bylaw, any director or the entire Board of Directors may

to vote at an election of directors.

                                  ARTICLE IV

                                   NOTICES

     SECTION 1. Whenever, under the provisions of the statutes or of the 
certificate of incorporation or of these bylaws, notice is required to be 
given to any director or stockholder, it shall not be construed to mean 
personal notice, but such notice may be given in writing, by mail, addressed

facsimile. In case any officer, transfer agent or registrar who has signed or 
whose facsimile signature has been placed upon a certificate shall have 
ceased to be such officer, transfer agent or registrar before such

authorizing such issue of a new certificate or certificates, the Board of

without a meeting, or entitled to receive payment of any dividend or other 
distribution or allotment of any rights, or entitled to exercise any rights 
in respect of any change, conversion or exchange of stock or for the purpose 
of any other lawful action, the Board of Directors may fix, in advance, a 
record date, which shall not be more than sixty (60) nor less than ten (10) 
days before the date of such meeting, nor more than sixty (60) days prior to 
any other action. A determination of stockholders of record entitled to 
notice of or to vote at a meeting of stockholders shall apply to any 
adjournment of the meeting; provided, however, that the Board of Directors 
may fix a new record date for the adjourned meeting.

                            REGISTERED STOCKHOLDERS

right of a person registered on its books as the owner of shares to receive

                                       9
<PAGE>

share or shares on the part of any other person, whether or not it shall have 
express or other notice thereof, except as otherwise provided by the laws of 
Delaware.

                                  ARTICLE VII

                              GENERAL PROVISIONS

                                   DIVIDENDS

     SECTION 1. Dividends upon the capital stock of the corporation, subject 
to the provisions of the certificate of incorporation, if any, may be 
declared by the Board of Directors at any regular or special meeting, 
pursuant to law. Dividends may be paid in cash, in property, or in shares of 
the capital stock, subject to the provisions of the certificate of 
incorporation.

     SECTION 2. Before payment of any dividend, there may be set aside out of 
any funds of the corporation available for dividends such sum or sums as the 
directors from time to time, in their absolute discretion, think proper as 
a reserve or reserves to meet contingencies, or for equalizing dividends, or 
for repairing or maintaining any property of the corporation, or for such 
other purposes as the directors shall think conducive to the interest of the 
corporation, and the directors may modify or abolish any such reserve in the 
manner in which it was created.

                                    CHECKS

     SECTION 3. All checks or demands for money and notes of the corporation 
shall be signed by such officer or officers or such other person or persons 
as the Board of Directors may from time to time designate.

     SECTION 4. The fiscal year of the corporation shall be fixed by 
resolution of the Board of Directors.

                                     SEAL

     SECTION 5. The Board of Directors may adopt a corporate seal having 
inscribed thereon the name of the corporation, the year of its organization 
and the words "Corporate Seal, Delaware". The seal may be used by causing it 
or a facsimile thereof to be impressed or affixed or reproduced or otherwise.

                                INDEMNIFICATION

     SECTION 6. The corporation shall, to the fullest extent authorized under 
the laws of the State of Delaware, as those laws may be amended and 
supplemented from time to time, indemnify any director made, or threatened to 
be made, a party to an action or proceeding, whether criminal, civil, 
administrative or investigative, by reason of being a director of the 
corporation or a predecessor corporation or, at the corporation's request, a 
director or officer of another corporation, provided, however, that the 
corporation shall indemnify any such agent in

                                      10
<PAGE>

connection with a proceeding initiated by such agent only if such proceeding 
was authorized by the Board of Directors of the corporation. The 
indemnification provided for in this Section 6 shall: (i) not be deemed 
exclusive of any other rights to which those indemnified may be entitled 
under any bylaw, agreement or vote of stockholders or disinterested directors 
or otherwise, both as to action in their official capacities and as to action 
in another capacity while holding such office, (ii) continue as to a person 
who has ceased to be a director, and (iii) inure to the benefit of the heirs, 
executors and administrators of such a person. The corporation's obligation 
to provide indemnification under this Section 6 shall be offset to the extent 
of any other source of indemnification or any otherwise applicable insurance 
coverage under a policy maintained by the corporation or any other person.

      Expenses incurred by a director of the corporation in defending a civil 
or criminal action, suit or proceeding by reason of the fact that he or she 
is or was a director of the corporation (or was serving at the corporation's 
request as a director or officer of another corporation) shall be paid by the 
corporation in advance of the final disposition of such action, suit or 
proceeding upon receipt of an undertaking by or on behalf of such director to 
repay such amount if it shall ultimately be determined that such director is 
not entitled to be indemnified by the corporation as authorized by relevant 
sections of the General Corporation Law of Delaware. Notwithstanding the 
foregoing, the corporation shall not be required to advance such expenses to 
an agent who is a party to an action, suit or proceeding brought by the 
corporation and approved by a majority of the Board of Directors of the 
corporation that alleges willful misappropriation of corporate assets by such 
agent, disclosure of confidential information in violation of such agent's 
fiduciary or contractual obligations to the corporation or any other willful 
and deliberate breach in bad faith of such agent's duty to the corporation or 
its stockholders.

     The foregoing provisions of this Section 6 shall be deemed to be a 
contract between the corporation and each director who serves in such 
capacity at any time while this bylaw is in effect, and any repeal or 
modification thereof shall not affect any rights or obligations then existing 
with respect to any state of facts then or theretofore existing or any 
action, suit or proceeding theretofore or thereafter brought based in whole 
or in part upon any such state of facts.

     The Board of Directors in its discretion shall have a power on behalf of 
the corporation to indemnify any person, other than a director, made a party 
to any action, suit or proceeding by reason of the fact that such person, 
their testator or intestate, is or was an officer or employee of the 
corporation.

     To assure indemnification under this Section 6 of all directors, officers 
and employees who are determined by the corporation or otherwise to be or to 
have been "fiduciaries" of any employee benefit plan of the corporation that 
may exist from time to time, Section 145 of the General Corporation of Law of 
Delaware shall, for the purposes of this Section 6, be interpreted as 
follows: an "other enterprise" shall be deemed to include such an employee 
benefit plan, including without limitation, any plan of the corporation that 
is governed by the Act of Congress entitled "Employee Retirement Income 
Security Act of 1974," as amended from time to time; the corporation shall be 
deemed to have requested a person to serve an employee

                                      11

<PAGE>

benefit plan where the performance by such person of his duties to the 
corporation also imposes duties on, or otherwise involves services by, such 
person to the plan or participants or beneficiaries of the plan; excise taxes 
assessed on a person with respect to an employee benefit plan pursuant to 
such Act of Congress shall be deemed "fines."

                                  ARTICLE VIII

                                   AMENDMENTS

     SECTION 1. These bylaws may be altered, amended or repealed or new 
bylaws may be adopted by stockholders holding at least seventy-five percent 
(75%) of the Company's outstanding capital stock ("Amending Stockholders") or 
by the Board of Directors, when such power is conferred upon the Board of 
Directors by the certificate of incorporation at any regular meeting of the 
stockholders or of the Board of Directors or by the Amending Stockholders at 
any special meeting of the stockholders or by the Board of Directors at any 
special meeting of the Board of Directors if notice of such alteration, 
amendment, repeal or adoption of new bylaws be contained in the notice of 
such special meeting. If the power to adopt, amend or repeal bylaws is 
conferred upon the Board of Directors by the certificate or incorporation it 
shall not divest or limit the power of the stockholders to adopt, amend or 
repeal bylaws.

                                   R E C I T A L S:

     A.   Pursuant to the terms and conditions of that certain Stock Purchase

     B.   In connection with the transactions contemplated by the Stock Purchase
Agreement, STAR has agreed to grant to the Holder the registration rights set

                                  A G R E E M E N T:

     NOW, THEREFORE, intending to be legally bound, the parties agree as
follows:

     1.   CERTAIN DEFINITIONS.  As used in this Agreement, the following terms
shall have the following meanings: 

          "Exchange Act" shall mean the Securities Exchange Act of 1934, as
amended from time to time.

          "Prospectus" shall mean the prospectus included in any Registration
Statement, as amended or supplemented by any prospectus supplement and including
post-effective amendments and all material incorporated by reference in such
Prospectus.

registration effected by preparing and filing a Registration Statement and
taking all other actions that are necessary or appropriate in connection
therewith, and the declaration or ordering of effectiveness of such Registration
Statement by the SEC.

          "Registration Expenses" shall have the meaning set forth in Section 5.

<PAGE>

          "Registrable Securities" shall mean (i) the Shares and (ii) any
securities issued or issuable with respect to such Shares by way of a stock
dividend, stock split, combination of shares, recapitalization, restructuring,
merger, consolidation or other reorganization of STAR, provided that such term
shall not include any such shares of Common Stock sold to the public by Holder
pursuant to a Registration Statement or to Rule 144 under the Securities Act or
sold by Holder in a private transaction in which Holder's rights hereunder were
not assigned, and shall not include any Shares that are eligible for resale to
the public pursuant to Rule 144(k) of the Securities Act.

          "Registration Statement" shall mean any registration statement of STAR
in compliance with the Securities Act that covers Registrable Securities
pursuant to the provisions of this Agreement, including, without limitation, the
Prospectus, all amendments and supplements to such Registration Statement or
Prospectus, including all post-effective amendments, all exhibits and all
material incorporated by reference in such Registration Statement.

          "Securities Act" shall mean the Securities Act of 1933, as amended
from time to time.

          "SEC" shall mean the Securities and Exchange Commission.

          "Underwritten registration" or "underwritten offering" shall mean a
registration in which securities of STAR are sold to an underwriter or through
an underwriter as agent for reoffering to the public.

     2.   STAR REGISTRATION.  If STAR shall determine to register any shares of
Common Stock for its own account or for the account of any stockholders (other
than a registration relating either to the sale of securities to employees of
STAR pursuant to a stock option, stock purchase or similar benefit plan or to an
SEC Rule 145 transaction), Holder shall be entitled to include Registrable
Securities in such registration (and related underwritten offering, if any) on
the following terms and conditions:

          (a)  STAR shall promptly give written notice of such determination to
Holder who shall have the right to request, by written notice given to STAR
within fifteen (15) days of the receipt by Holder of such notice, that a
specific number of Registrable Securities be included in such Registration
Statement.

          (b)  If the Registration Statement relates to an underwritten
offering, the notice called for by Section 2(a) shall specify the name of the
managing underwriter for such offering and the number of securities to be
registered for the account of STAR and, if then known, for the account of any of
the other stockholders of STAR.

                                          2
<PAGE>

          (c)  If the Registration Statement relates to an underwritten
offering, Holder agrees to enter into an underwriting agreement containing
standard and customary terms and conditions and to sell his Registrable
Securities pursuant to the terms thereof.

          (d)  If the managing underwriter for the underwritten offering under
the Registration Statement to be filed by STAR determines that inclusion of all
or any portion of the Registrable Securities in such offering would adversely
affect the ability of the underwriter for such offering to sell all of the
securities requested to be included for sale in such offering, the number of
shares that may be included in such registration in such offering shall be
allocated as follows:  (i) first, STAR shall be permitted to include all shares
of capital stock to be registered thereby and (ii) second, Holder shall be
allowed to include such additional amount as the managing underwriter deems
appropriate, such amount to be allocated among Holder and any other selling
stockholders on a pro rata basis based on the total number of shares of capital
stock held thereby.  The foregoing sentence notwithstanding, if the underwritten
offering is being registered by STAR at the instance of another shareholders or
shareholders to whom STAR has granted the right to require that STAR undertake
such registration (hereinafter, "Demand Right Holders"), then the managing
underwriter of such offering may reduce the number of Holder's Registrable
Securities included in such offering, or exclude them entirely, without any
reduction of the shares to be included in such offering by any such Demand Right
Holders.

          (e)  Holder shall have the right to withdraw his Registrable
Securities from the Registration Statement at any time prior to the effective
date thereof, but if the same relates to an underwritten offering and an
underwriting agreement has been entered into, he may only do so during the time
period and on terms deemed appropriate by the underwriters for such underwritten
offering as specified in such underwriting agreement.

          (f)  STAR shall have the right to terminate or withdraw any
registration initiated by it under this Section 2 prior to the effective date of
such registration, whether or not Holder has elected to include Registrable
Securities in such registration.

          (g)  All registration rights set forth herein shall expire within two
years after the date of this Agreement.

     3.   RESTRICTIONS ON PUBLIC SALE BY HOLDER.  If Holder's Registrable
Securities are included (in whole or in part) in a Registration Statement filed
by STAR under Section 2 for sale in an underwritten offering, Holder agrees, if
requested by the managing underwriter of such offering, not to sell, make any
short sale of, loan, grant any option for the purchase of, dispose of or effect
any public sale or distribution of securities of the same series and class as
(or securities exchangeable or exercisable for or convertible into securities of
the same series and class as) the Registrable Securities included in the
Registration Statement, including a sale pursuant to Rule 144 under the
Securities Act (except as part of such underwritten registration), during the
ten (10)-day period prior to, and during the one hundred eighty (180)-

                                          3
<PAGE>

day period (or shorter period requested by the underwriter) beginning on the
closing date of such underwritten offering, to the extent timely notified in
writing by STAR or the managing underwriter.

     4.   REGISTRATION PROCEDURES.  In the case of each registration,
qualification or compliance effected by STAR pursuant to this Agreement, STAR
shall, by notice to Holder, keep Holder advised in writing as to the initiation,
progress and effective date of each registration, qualification and compliance
and, in connection with STAR's registration obligations pursuant to Section 2
hereof, subject to Sections 2(d) and 2(f), STAR will use its best efforts to
effect such registration to permit the offer and sale of the Registrable
Securities proposed to be included in a Registration Statement in accordance
with the intended method or methods of disposition thereof, and pursuant thereto
STAR will as expeditiously as possible:

          (a)  prepare and file with the SEC a Registration Statement with
respect to such Registrable Securities and use its best efforts to cause such
Registration Statement to become effective as soon as practicable thereafter,
and, upon the request of Holder, keep such registration statement effective for
up to 120 days, provided that, before filing any Registration Statement or
Prospectus or any amendments or supplements thereto, STAR will furnish to Holder
and his counsel, copies of all such documents proposed to be filed, at least ten
(10) days prior to the filing thereof, including, without limitation, documents
incorporated by reference in the Prospectus and, if requested by the Holder, the
exhibits incorporated by reference therein, and Holder shall have the
opportunity to object to any information pertaining solely to Holder that is
contained therein and STAR will make the corrections reasonably requested by
Holder with respect to such information prior to filing any Registration
Statement or amendment thereto or any Prospectus or any supplement thereto. 
STAR will not include or name Holder in any Registration Statement or Prospectus
without the consent of Holder, unless required to do so by the Securities Act
and the rules and regulations thereunder.

          (b)  prepare and file with the SEC such amendments, post-effective
amendments and supplements to the Registration Statement and the Prospectus as
may be necessary to keep such Registration Statement effective for a period of
up to 120 days, or such shorter period as is necessary to complete the
distribution of the securities covered by such Registration Statement and to
comply with the provisions of the Securities Act and the rules and regulations
thereunder with respect to the disposition of all securities covered by such
Registration Statement.

          (c)  promptly notify Holder (i) when the Registration Statement, any
pre-effective amendment, the Prospectus or any Prospectus supplement or
post-effective amendment has been filed, and, with respect to the Registration
Statement or any post-effective amendment, when the same has become effective,
(ii) of any request by the SEC for amendments or supplements to the Registration
Statement or the Prospectus or for additional information, (iii) of the issuance
by the SEC of any stop order suspending the 

                                          4
<PAGE>

effectiveness of the Registration Statement or the initiation of any proceedings
for that purpose, (iv) of the receipt by STAR of any notification with respect
to the suspension of the qualification of the Registrable Securities for sale in
any jurisdiction or the initiation or threatening of any proceeding for such
purpose and (v) of the happening of any event which makes any statement made in
the Registration Statement, the Prospectus or any document incorporated therein
by reference untrue or which requires the making of any changes in the
Registration Statement, the Prospectus or any document incorporated therein by
reference in order to make the statements therein not misleading.

          (d)  make every reasonable effort to obtain the withdrawal of any
order suspending the effectiveness of the Registration Statement at the earliest
possible moment.

          (e)  furnish to Holder, without charge, at least one signed copy of
the Registration Statement and any amendment or supplement thereto, the
Prospectus included in such Registration Statement (including, without
limitation, each preliminary prospectus), including financial statements and
schedules, all documents incorporated therein by reference and all exhibits
(including those incorporated by reference) and such other documents as Holder
may reasonably request in order to facilitate the disposition of the Registrable
Securities.  

          (f)  deliver to Holder, without charge, such reasonable number of
conformed copies of the Registration Statement (including any amendment or
supplement thereto) and such number of copies of the Prospectus (including each
preliminary prospectus) and any amendment or supplement thereto (and any
documents incorporated by reference therein) as Holder may reasonably request,
all in full conformity with the Securities Act; STAR consents to the use of the
Prospectus or any amendment or supplement thereto by Holder in connection with
the offer and sale of the Registrable Securities covered by the Prospectus or
any amendment or supplement thereto.

          (g)  prior to any offering of Registrable Securities covered by a
Registration Statement, register or qualify or cooperate with Holder in
connection with the registration or qualification of such Registrable Securities
for offer and sale under the securities or blue sky laws of such jurisdictions
as Holder reasonably requests, and use its best efforts to keep each such
registration or qualification effective, including through new filings, or
amendments or renewals, during the period such Registration Statement is
required to be kept effective pursuant to the terms of this Agreement; and do
any and all other acts or things necessary or advisable to enable the
disposition in all such jurisdictions reasonably requested by Holder of the
Registrable Securities covered by such Registration Statement, provided that
under no circumstances shall STAR be required in connection therewith or as a
condition thereof to qualify to do business or to file a general consent to
service of process in any such states or jurisdictions.

                                          5

          (h)  upon the occurrence of any event contemplated by Section 
4(c)(v) above, prepare a supplement or post-effective amendment to the 
Registration Statement or the Prospectus or any document incorporated therein 
by reference or file any other required document so that, as thereafter 
delivered to the purchasers of the Registrable Securities, the Prospectus 
will not contain an untrue statement of a material fact or omit to state any 
material fact necessary to make the statements therein not misleading.

          (i)  make generally available to Holder consolidated earnings 
statements satisfying the provisions of Section 11(a) of the Securities Act 
and Rule 158 thereunder, as soon as practicable after the end of any twelve 
(12)-month period (or ninety (90) days, if such period is a fiscal year) (i) 
commencing at the end of any fiscal quarter in which Registrable Securities 
are sold to  underwriters in a firm or best efforts underwritten offering, or 
(ii) if not sold to underwriters in such an offering, beginning with the 
first month of STAR's first fiscal quarter commencing after the effective 
date of the Registration Statement, which statements shall cover said twelve 
(12)-month period.

          (j)  use its best efforts to cause all Registrable Securities covered
by each Registration Statement to be listed subject to notice of issuance, prior
to the date of the first sale of such Registrable Securities pursuant to such
Registration Statement, on each securities exchange on which the Common Stock
issued by STAR are then listed, and admitted to trading on The Nasdaq Stock
Market, if the Common Stock is then admitted for quotation on The Nasdaq Stock
Market.

          (k)  in the case of an underwritten offering, cause to be delivered to
Holder and the underwriters, if any, opinions of counsel to STAR in customary
form, covering such matters as are customarily covered by opinions for an
underwritten public offering as the underwriters may request and addressed to
the underwriters and Holder.

          (l)  make available for inspection by Holder, any underwriter
participating in any disposition pursuant to such Registration Statement, and
any attorney, accountant or other agent retained by Holder or any underwriter,
all financial and other records, pertinent corporate documents and properties of
STAR, and cause STAR's officers, directors, employees and independent
accountants to supply all information reasonably requested by Holder or any such
underwriter, attorney, accountant or agent in connection with such Registration
Statement;

          (m)  provide a transfer agent and registrar for all such Registrable
Securities not later than the effective date of such Registration Statement;

          (n)  cause to be delivered, immediately prior to the effectiveness of
the Registration Statement (and, in the case of an underwritten offering, at the
time of delivery of any Registrable Securities sold pursuant thereto), letters
from STAR's independent certified public accountants addressed to Holder and
each underwriter, if any, stating that such 

                                          6
<PAGE>

accountants are independent public accountants within the meaning of the
Securities Act and the applicable published rules and regulations thereunder,
and otherwise in customary form and covering such financial and accounting
matters as are customarily covered by letters of the independent certified
public accountants delivered in connection with primary or secondary
underwritten public offerings, as the case may be.

     Holder agrees that, upon receipt of any notice from STAR of the happening
of any event of the kind described in clauses (ii) through (v) of Section 4(c)
hereof, Holder will forthwith discontinue disposition of Registrable Securities
under the Prospectus related to the applicable Registration Statement until
Holder's receipt of the copies of the supplemented or amended Prospectus, or
until he is advised in writing by STAR that the use of the Prospectus may be
resumed.  It shall be a condition precedent to the obligations of STAR to take
any action pursuant to this Section 4 with respect to the Registrable Securities
of Holder that Holder shall furnish to STAR such information regarding himself
and the Registrable Securities held by him as shall be required by the
Securities Act to effect the registration of Holder's Registrable Securities.

     5.   REGISTRATION EXPENSES.  All expenses incident to any registration to
be effected hereunder and incident to STAR's performance of or compliance with
this Agreement, including without limitation all registration, filing and
qualification fees, fees and expenses of compliance with securities or blue sky
laws, printing expenses, messenger and delivery expenses, NASD, stock exchange
and qualification fees, fees and disbursements of STAR's counsel and of
independent certified public accountants of STAR (all such expenses being herein
called "Registration Expenses") will be borne by STAR.  Holder shall bear (i)
all underwriting commissions (and transfer taxes, if any) relating to the
Registrable Securities registered and (ii) the fees and expenses of his legal
counsel and accountants.

     6.   INDEMNIFICATION.

          (a)  INDEMNIFICATION BY STAR.  If Holder's Registrable Securities are
sold under a Prospectus which is a part of a Registration Statement, STAR agrees
to indemnify and hold harmless Holder from and against any and all losses,
claims, damages and liabilities (including any investigation, legal or other
expenses reasonably incurred in connection with, and any amount paid in
settlement of, any action, suit or proceeding or any claim asserted) to which
Holder may become subject under the Securities Act, the Exchange Act or other
federal or state statutory law or regulation, at common law or otherwise,
insofar as such losses, claims, damages or liabilities arise out of or are based
upon (i) any untrue statement or alleged untrue statement of a material fact
contained in any Registration Statement, Prospectus or preliminary prospectus or
any amendment or supplement thereto, (ii) the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading and (iii) any violation or alleged
violation by STAR of the Securities Act, the Exchange Act or any state
securities or blue sky laws in connection with the Registration Statement,
Prospectus or preliminary prospectus or any amendment or supplement 

                                          7
<PAGE>

thereto, provided that STAR will not be liable to Holder to the extent that such
loss, claim, damage or liability arises from or is based upon any untrue
statement of a material fact or omission of a material fact that was made in
such Registration Statement, Prospectus or preliminary prospectus or any
amendment or supplement thereto in reliance upon and in conformity with written
information furnished to STAR by Holder expressly for use therein.

          (b)  INDEMNIFICATION OF STAR BY HOLDER.  If Holder's Registrable
Securities are sold under a Prospectus which is a part of a Registration
Statement, Holder agrees to indemnify and hold harmless STAR, its directors and
each officer who signed such Registration Statement and each person who controls
STAR (within the meaning of Section 15 of the Securities Act) from and against
any and all losses, claims, damages and liabilities (including any
investigation, legal or other expenses reasonably incurred in connection with,
and any amount paid in settlement of, any action, suit or proceeding or any
claim asserted) to which STAR or any other such person may become subject under
the Securities Act, the Exchange Act or other federal or state statutory law or
regulation, at common law or otherwise, insofar as such losses, claims, damages
or liabilities arise out of or are based upon (i) any untrue statement or
alleged untrue statement of a material fact contained in any Registration
Statement, Prospectus or preliminary prospectus or any amendment or supplement
thereto, (ii) the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading and (iii) any violation or alleged violation by STAR of the
Securities Act, the Exchange Act or any state securities or blue sky laws in
connection with the Registration Statement, Prospectus or preliminary prospectus
or any amendment or supplement thereto, but in each case only to the extent that
such losses, claims, damages and liabilities arise out of or are based upon any
untrue statement of a material fact or omission of a material fact that was made
in the Prospectus, the Registration Statement, or any amendment or supplement
thereto, in reliance upon and in conformity with information furnished in
writing to STAR by Holder expressly for use therein, provided that in no event
shall the aggregate liability of Holder exceed the amount of the net proceeds
received by Holder upon the sale of the Registrable Securities giving rise to
such indemnification obligation.  STAR and Holder shall be entitled to receive
indemnities from underwriters, selling brokers, dealer managers and similar
securities industry professionals participating in the distribution, to the same
extent as customarily furnished by such persons in similar circumstances.

          (c)  CONDUCT OF INDEMNIFICATION PROCEEDINGS.  Any person entitled to
indemnification hereunder will (i) give prompt notice to the indemnifying party
of any claim with respect to which it seeks indemnification and (ii) permit such
indemnifying party to assume the defense of such claim with counsel reasonably
satisfactory to the indemnified party, provided that any person entitled to
indemnification hereunder shall have the right to employ separate counsel and to
participate in the defense of such claim, but the fees and expenses of such
counsel shall be at the expense of such person and not of the indemnifying party
unless (A) the indemnifying party has agreed to pay such fees or expenses,
(B) the indemnifying party shall have failed to assume the defense of such claim
and employ counsel reasonably 

                                          8
<PAGE>

satisfactory to such person, or (C) in the reasonable judgment of such person,
based upon advice of their counsel, a conflict of interest may exist between
such person and the indemnifying party with respect to such claims (in which
case, if the person notifies the indemnifying party in writing that such person
elects to employ separate counsel at the expense of the indemnifying party, the
indemnifying party shall not have the right to assume the defense of such claim
on behalf of such person).  If such defense is not assumed by the indemnifying
party, the indemnifying party will not be subject to any liability for any
settlement made without consent (but such consent will not be unreasonably
withheld or delayed).  No indemnified party will be required to consent to entry
of any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by all claimants or plaintiffs to such
indemnified party of a release from all liability in respect to such claim or
litigation.  Any indemnifying party who is not entitled to, or elects not to,
assume the defense of a claim will not be obligated to pay the fees and expenses
of more than one counsel for all parties indemnified by such indemnifying party
with respect to such claim.  As used in this Section 6(c), the terms
"indemnifying party", "indemnified party" and other terms of similar import are
intended to include only STAR (and its officers, directors and control persons
as set forth above) on the one hand, and Holder on the other hand, as
applicable.

          (d)  CONTRIBUTION.  If for any reason the foregoing indemnity is
unavailable or insufficient to hold harmless an indemnified party in respect of
any losses, claims, damages, liabilities or expenses (or actions in respect
thereof), then the indemnifying party shall contribute to the amount paid or
payable by the indemnified party as a result of such losses, claims, damages,
liabilities or expenses (or actions in respect thereof) in such proportion as is
appropriate to reflect the relative fault of the indemnifying party on the one
hand and the indemnified party on the other hand in connection with statements
or omissions which resulted in such losses, claims, damages, liabilities or
expenses (or actions in respect thereof), as well as any other relevant
equitable considerations.  The relative fault shall be determined by reference
to, among other things, whether the untrue or alleged untrue statement of a
material fact or the omission or alleged omission to state a material fact
relates to information supplied by the indemnifying party or the indemnified
party and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such untrue statement or omission. 
Notwithstanding the foregoing, Holder shall not be required to contribute any
amount in excess of the amount Holder would have been required to pay to an
indemnified party if the indemnity under Section 6(b) hereof was available.  No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

          (e)  OTHER RIGHTS.  The provisions of this Section 6 shall be in
addition to any other rights of indemnification or contribution which any
indemnified party may have pursuant to law, equity, contract or otherwise and
shall remain in full force and effect regardless of any investigation made by or
on behalf of an indemnified party.

                                          9
<PAGE>

          (f)  TIMING OF PAYMENTS.  An indemnifying party shall make payments of
all amounts required to be made pursuant to the foregoing provisions of this
Section 6 to or for the account of the indemnified party from time to time
promptly upon receipt of bills or invoices relating thereto or when otherwise
due or payable.

          (g)  SURVIVAL.  The indemnity and contribution agreements contained in
this Section 6 shall remain in full force and effect and shall survive the
transfer of such Registrable Securities by Holder.

     7.   RULE 144.  STAR covenants that it will file, on a timely basis, the
reports required to be filed by it under the Securities Act and the Exchange Act
and the rules and regulations adopted by the SEC thereunder, and it will take
such further action as Holder may reasonably request (including, without
limitation, compliance with the current public information requirements of
Rule 144(c) under the Securities Act), all to the extent required from time to
time to enable Holder to sell Registrable Securities without registration under
the Securities Act within the limitation of the conditions provided by Rule 144
under the Securities Act, as such Rule may be amended from time to time, or any
similar rule or regulation hereafter adopted by the SEC.  Upon the request of
Holder, STAR will deliver to Holder a written statement verifying that it has
complied with such requirements.

     8.   NO INCONSISTENT AGREEMENTS.  STAR will not enter into any agreement
offering registration rights to any holders of Common Stock that conflict with
or violate the rights set forth herein without the consent of Holder, which
consent may be granted or withheld in the sole discretion of Holder.

     9.   ASSIGNMENT OF RIGHTS.  Holder may assign his rights under this
Agreement to any transferee of Registrable Securities, if (i) such transferee
has acquired at least twenty-five percent (25%) of the Registrable Securities
originally held by Holder, and (ii) such transferee has executed a writing
wherein such transferee agrees to be bound by the terms hereof.

     10.  NOTICES.  All notices required or permitted under the terms of this
Agreement shall be delivered in the manner called for in the Stock Purchase
Agreement. 

     11.  SUCCESSORS AND ASSIGNS.  This Agreement shall inure to the benefit of
and be binding upon Holder and his legal representatives, successors and
assigns, and upon STAR and its successors and assigns, including without
limitation any corporation resulting from any merger or consolidation of STAR
with or into such corporation (in which STAR is not the surviving corporation)
or any corporation whose securities are issued in exchange for STAR's shares of
common stock.

     12.  SEVERABILITY.  In the event that any one or more of the provisions
contained herein, or the application thereof in any circumstance, is held
invalid, illegal or unenforceable, 

                                          10
<PAGE>



the validity, legality and enforceability of any such provision in every other
respect and of the remaining provisions contained herein shall not be affected
or impaired thereby.

     13.  ENTIRE AGREEMENT.  This Agreement constitutes the entire agreement of
the parties with respect to the subject matter hereof and shall supersede and
preempt any prior understandings, agreements or representations, written or
oral, by or among the parties hereto.

     14.  COUNTERPARTS.  This Agreement may be executed (including by facsimile
transmission) with counterpart signature pages or in any number of counterparts,
each of which shall be original, and all of which together shall constitute one
instrument.  

     15.  AMENDMENT.  Any provision of this Agreement may be amended, waived or
modified only by a writing signed by STAR and by Holder.

     16.  GOVERNING LAW.  This Agreement and the legal relations between the
parties shall be governed by and construed in accordance with the laws of the
State of Delaware.

     17.  RECAPITALIZATION, EXCHANGES, ETC., AFFECTING STAR'S CAPITAL STOCK. 
The provisions of this Agreement shall apply, to the full extent set forth
herein with respect to any and all shares of capital stock of STAR or any
successor or assign of STAR (whether by merger, consolidation, sale of assets or
otherwise)  which may be issued in respect of, in exchange for or in
substitution of, the Registrable Securities and shall be appropriately adjusted
for any stock dividends, splits, reverse splits, combinations, recapitalizations
and the like occurring after the date hereof.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of
the day and year first above written.

credit basis and in Dollars or in any Optional Currency to the Borrower from 
time to time and (ii) to participate in standby and/or commercial letters of 
credit issued for the account of the Borrower pursuant to Section 2.3 from 
time to time (each a "Letter of Credit" and, collectively, the "Letters of 
Credit"), from and including the Closing Date to but excluding the Facility 
Termination Date in an amount not to exceed the amount of its Commitment.  Up 
to $10,000,000 in aggregate principal amount of the Aggregate Commitment may 
be borrowed in Optional Currencies by the Borrower pursuant to the provisions 
of Section 2.2 hereof.  The sum of (i) the aggregate principal amount of all 
Loans outstanding (including Loans in any Optional Currency calculated at the 
Dollar Equivalent thereof), (ii) the aggregate Letter of Credit Amount of all 
Letters of Credit outstanding and (iii) the aggregate amount of unreimbursed 
drawings under all Letters of Credit, shall not exceed, at any time, the  
Borrowing Base.  The Borrowing Base availability shall be determined on the 
basis of the Borrowing Base Certificate which is delivered on the Closing 
Date and in accordance with Section 7.1(iv).  Further, the sum of (x) the 
aggregate Letter of Credit Amount of all Letters of Credit 

                                      -15-

<PAGE>

outstanding and (y) the aggregate amount of unreimbursed drawings under all 
Letters of Credit shall not exceed $8,000,000 at any time.  Within the limit 
of each Lender's Commitment and as set forth herein, the Borrower may borrow, 
have Letters of Credit issued and/or renewed for its account, prepay Loans, 
reborrow and have additional Letters of Credit issued for its account.

     2.2  OPTIONAL CURRENCIES.  The Borrower shall be entitled to request Loans
on a revolving credit basis and in an Optional Currency from time to time from
and including the Closing Date to but excluding the Facility Termination Date by
giving the Agent a notice of borrowing pursuant to the provisions of
Section 2.14 hereof.  The sum of the aggregate amount of all Optional Currency
Loans to the Borrower shall not at any time exceed $10,000,000.


     2.3  ISSUANCE OF LETTERS OF CREDIT.

     (i)  The Borrower shall be entitled to request the issuance of standby
and/or commercial Letters of Credit from time to time from and including the
Closing Date to but excluding the date which is seven Business Days prior to the
Facility Termination Date by giving the Agent a Letter of Credit Request at
least three Business Days before the requested date of issuance of such Letter
of Credit (provided that such Letter of Credit Request is received by the Agent
no later than 11:00 a.m., Los Angeles time, and any Letter of Credit Request
received after such time shall be deemed to have been received on the next
Business Day) (which date of issuance shall be a Business Day).  No Letter of
Credit shall have an expiration date beyond the Facility Termination Date.  The
aggregate Letter of Credit Amounts under all outstanding Letters of Credit and
the aggregate amount of unreimbursed drawings under Letters of Credit shall
reduce, dollar for dollar, the Aggregate Available Commitment.  Letters of
Credit may only be requested in Dollars.  The sum of (a) the aggregate Letter of
Credit Amount of all Letters of Credit outstanding and (b) the aggregate amount
of unreimbursed drawings under all Letters of Credit shall not at any time
exceed $8,000,000.  In addition, the sum of (i) the aggregate principal amount
of all Loans outstanding, (ii) the aggregate Letter of Credit Amount of all
Letters of Credit outstanding and (iii) the aggregate amount of unreimbursed
drawings under all Letters of Credit shall not exceed, at any time, the 
Borrowing Base.  Each Letter of Credit Request shall be made in writing, shall
be signed by an Authorized Officer, shall be irrevocable and shall be effective
upon receipt by the Agent.  Provided that a valid Letter of Credit Request has
been received by the Agent and upon fulfillment of the other applicable
conditions set forth in Section 4.3, the Agent will issue the requested Letter
of Credit from its office specified in Section 15.1.

                                      -16-


<PAGE>


     Letters of Credit shall be used only for the purpose of supporting the 
operations of the Borrower and its Subsidiaries incurred in the ordinary course
of business.

     (ii)   Immediately upon the issuance of each Letter of Credit, the Agent
shall be deemed to have sold and transferred to each Lender, and each Lender
shall be deemed to have purchased and received from the Agent, in each case
irrevocably and without any further action by any party, an undivided interest
and participation in such Letter of Credit, each drawing thereunder and the
obligations of the Borrower under this Agreement in respect thereof in an amount
equal to the product of (i) such Lender's Commitment Percentage and (ii) the
maximum amount available to be drawn under such Letter of Credit (assuming
compliance with all conditions to drawing).  The Agent shall promptly advise
each Lender of the issuance of each Letter of Credit, the Letter of Credit
Amount of such Letter of Credit, any change in the face amount or expiration
date of such Letter of Credit, the cancellation or other termination of such
Letter of Credit and any drawing under such Letter of Credit.

     (iii)  The payment by the Agent of a draft drawn under any Letter of
Credit shall first be made from any cash collateral deposit held by the Agent
with respect to such Letter of Credit.  After any such cash collateral deposit
has been applied, and unless the Borrower has repaid any remaining amount due to
the Agent pursuant to the Agent's payment on such Letter of Credit, the payment
by the Agent of a draft drawn under any Letter of Credit shall constitute for
all purposes of this Agreement the making by the Agent in its individual
capacity as a Lender hereunder (in such capacity, the "Drawing Lender") of a
Reference Rate Loan in the amount of such payment (but without any requirement
of compliance with the conditions set forth in Section 4.3).  In the event that
any such Loan by the Drawing Lender resulting from a drawing under any Letter of
Credit is not repaid by the Borrower by 12:00 noon, Los Angeles time, on the day
of payment of such drawing, the Agent shall promptly notify each other Lender. 
Each Lender shall, on the day of such notification (or if such notification is
not given by 1:00 p.m., Los Angeles time, on such day, then on the next
succeeding Business Day), make a Reference Rate Loan, which shall be used to
repay the applicable portion of the Reference Rate Loan of the Drawing Lender
with respect to such Letter of Credit drawing, in an amount equal to the amount
of such Lender's participation in such drawing for application to repay the
Drawing Lender (but without any requirement of compliance with the applicable
conditions set forth in Section 4.3) and shall deliver to the Agent for the
account of the Drawing Lender, on the day of such notification (or if such
notification is not given by 1:00 p.m., Los Angeles time, on such day, then on
the next succeeding Business Day) and in immediately available funds, the amount
of such Reference Rate Loan.  In the event that any Lender fails to make
available to the Agent for the account of the Drawing Lender the amount of such
Reference Rate


                                      -17-

<PAGE>

Loan, the Drawing Lender shall be entitled to recover such amount on demand 
from such Lender together with interest thereon at the Federal Funds Rate.

     (iv) The obligations of the Borrower with respect to any Letter of Credit,
any Letter of Credit Request and any other agreement or instrument relating to
any Letter of Credit and any  Reference Rate Loan made under Section 2.3(iii)
shall be absolute, unconditional and irrevocable and shall be paid strictly in
accordance with the terms of the aforementioned documents under all
circumstances, including the following:

          (a)  any lack of validity or enforceability of any Letter of Credit,
this Agreement or any other Loan Document;

          (b)  the existence of any claim, setoff, defense or other right that
the Borrower may have at any time against any beneficiary or transferee of any
Letter of Credit (or any Person for whom any such beneficiary or transferee may
be acting), the Agent, any Lender (other than the defense of payment to a Lender
in accordance with the terms of this Agreement) or any other Person, whether in
connection with this Agreement, any other Loan Document, the transactions
contemplated hereby or thereby or any unrelated transaction;

          (c)  any statement or other document presented under any Letter of
Credit proving to be forged, fraudulent, invalid or insufficient in any respect,
or any statement therein being untrue or inaccurate in any respect whatsoever;

          (d)  payment by the Agent under any Letter of Credit against
presentation of a draft or certificate that does not comply on its face with the
terms of such Letter of Credit;

          (e)  any exchange, release or nonperfection of any collateral, or any
release, amendment or waiver of or consent to departure from any Loan Document
or other guaranty, for any of the Obligations of the Borrower in respect of the
Letters of Credit; and

          (f)  any other circumstance or happening whatsoever, whether or not
similar to any of the foregoing.

     (v)  The Borrower shall pay to the Agent with respect to each Letter of
Credit issued hereunder, the following fees:

          (a)  for each standby Letter of Credit, a Letter of Credit Fee to 
the Agent for the pro rata benefit of the Lenders (provided that the Agent 
shall retain for its account alone the initial $250 of any such Letter of 
Credit Fee as an issuance fee), equal to the product of (i) the Applicable 
Margin and (ii) the Letter of Credit Amount of such Letter of Credit (such 
fee to be payable on the date such Letter of Credit is issued);

                                      -18-

<PAGE>

          (b)  for each commercial Letter of Credit a letter of credit fee
to the Agent for the pro rata benefit of the Lenders (provided that the Agent
shall retain for its account alone the initial $120 of any such fee as an
issuance fee) equal to Agent's standard fees for issuance of commercial letters
of credit;  and

          (c)  from time to time, such additional fees and charges (including
cable charges) as are generally associated with letters of credit, in accordance
with the Agent's standard internal charge guidelines and the related Letter of
Credit Request.

     (vi)      The terms of this Agreement shall take precedence if there is any
inconsistency between the terms of this Agreement and the terms of any Letter of
Credit Request utilized by the Agent.

     (vii)     The Borrower assumes all risks of the acts or omissions of any
beneficiary or transferee of any Letter of Credit with respect to its use of
such Letter of Credit.  Neither the Agent nor any Lender nor any of their
respective officers or directors shall be liable or responsible for (i) the use
that may be made of any Letter of Credit or any acts or omissions of any
beneficiary or transferee in connection therewith; (ii) in the absence of any
gross negligence or willful misconduct by the Agent, the validity, sufficiency
or genuineness of documents, or of any endorsement thereof, even if such
documents should prove to be in any or all respects invalid, insufficient,
fraudulent or forged; (iii) in the absence of any gross negligence or willful
misconduct by the Agent, payment by the Agent against presentation of documents
that do not comply with the terms of any Letter of Credit, including failure of
any documents to bear any reference or adequate reference to any Letter of
Credit; or (iv) in the absence of any gross negligence or willful misconduct by
the Agent, any other circumstance whatsoever in making or failing to make
payment under any Letter of Credit.  In furtherance and not in limitation of the
foregoing, the Agent may accept any document that appears on its face to be in
order, without responsibility for further investigation, regardless of any
notice or information to the contrary.

     2.4  COMMITMENT PERCENTAGE.  The principal amount of each Lender's Loan 
and participation in a Letter of Credit shall be in an amount equal to the 
product of (i) such Lender's Commitment Percentage (expressed as a fraction) 
and (ii) the total amount of the Loan or Loans or Letters of Credit 
requested; PROVIDED THAT in no event shall any Lender be obligated to make a 
Loan if, after giving effect to such Loan, such Lender's Loans, its 
Commitment Percentage of the aggregate Letter of Credit Amount of all Letters 
of Credit outstanding and its Commitment Percentage of the aggregate amount 
of unreimbursed drawings under all Letters of Credit outstanding

                                      -19-

<PAGE>


would exceed its Commitment or if the amount of such requested Loan is in 
excess of such Lender's Available Commitment.

     2.5  TYPES OF LOANS.  Except as limited herein, the Loans may from time to
time be (i) Fixed Rate Loans, (ii) Reference Rate Loans or (iii) a combination
thereof, as determined by the Borrower and notified to the Agent in accordance
with Section 2.14.  Notwithstanding the foregoing, the initial Loans made on the
Closing Date shall be made as Reference Rate Loans and shall be subject to
conversion to Fixed Rate Loans pursuant to Section 2.13.  Each Lender may make
or maintain its Loans to the Borrower by or through any Applicable Lending
Office.

     2.6  EVIDENCE OF OBLIGATIONS.  The Loans made by each Lender to the
Borrower shall be evidenced by a Note, with appropriate insertions therein as to
payee, date and principal amount, payable to the order of such Lender and
representing the obligation of the Borrower to pay the aggregate unpaid
principal amount of all Loans made by such Lender to the Borrower, with interest
thereon as prescribed in Sections 2.16 and 2.17.  Each Lender is hereby
authorized (but not required) to record the date and amount of each payment or
prepayment of principal of its Loans made to the Borrower, each continuation
thereof, each conversion of all or a portion thereof to another Type or Optional
Currency and, in the case of Fixed Rate Loans, the length of each Interest
Period with respect thereto, in the books and records of such Lender, and any
such recordation shall constitute PRIMA FACIE evidence of the accuracy of the
information so recorded.  The failure of any Lender to make any such recordation
or notation in the books and records of the Lender (or any error in such
recordation or notation) shall not affect the obligations of the Borrower
hereunder or under the Notes.  Each Note shall (i) be dated the Closing Date,
(ii) provide for the payment of interest in accordance with Sections 2.16 and
2.17 and (iii) be stated to be payable on the Facility Termination Date.  

     2.7  COMMITMENT REDUCTION.  At the Borrower's option and upon at least five
Business Days' prior irrevocable written notice to the Agent, with such notice
specifying the amount and the date of such reduction, the Borrower may
permanently reduce the Aggregate Commitment in whole at any time or in part from
time to time; provided, however, that each partial reduction of the Aggregate
Commitment shall be in an aggregate amount equal to at least $1,000,000 or an
integral multiple of $100,000.  The Agent shall promptly notify each Lender (by
telecopy or by telephone) of such requested Commitment reduction.

     Reductions of the Aggregate Commitment pursuant to this Section 2.7 shall
automatically effect a reduction of the Commitment of each Lender to an amount
equal to the product of (i) the Aggregate Commitment of all Lenders, as reduced
pursuant to this Section 2.7 and (ii) the Commitment Percentage of such 


                                      -20-

<PAGE>

Lender, in each case determined immediately prior to such reduction of the 
Aggregate Commitment on such date.  Any such Commitment reduction shall be 
applied as the Borrower directs, but in the absence of any such direction, 
all sublimits shall be ratably reduced.

     Upon each reduction of the Aggregate Commitment, the Borrower shall (i) pay
the unused commitment fee, payable pursuant to Section 2.10, accrued on the
amount of the Aggregate Commitment so reduced through the date of such
reduction, (ii) prepay the amount, if any, by which the sum of (a) the aggregate
unpaid principal amount of the Loans, (b) the aggregate Letter of Credit Amount
of all Letters of Credit outstanding and (c) the aggregate amount of
unreimbursed drawings under all Letters of Credit exceeds the amount of the
Aggregate Commitment as so reduced, together with accrued interest on the amount
being prepaid to the date of such prepayment (or, with respect to outstanding
Letters of Credit, make a cash collateral deposit in an amount equal to such
excess to the extent such excess is not corrected by the foregoing prepayment)
and (d) compensate the Lenders for their funding costs, if any, in accordance
with Section 3.1(i).

     2.8  COMMITMENT TERMINATION.  The Commitment of each Lender and the
Aggregate Commitment shall terminate on the Facility Termination Date.

     2.9  REQUIRED PAYMENTS.  The outstanding Loans and all other unpaid
Obligations shall be paid in full by the Borrower on the Facility Termination
Date.

     2.10 UNUSED COMMITMENT FEE.  The Borrower agrees to pay to the Agent for
the benefit of the Lenders an unused commitment fee to be shared among Lenders
on the basis of their respective Commitment Percentages with respect to the
Commitments for the period from and including the Closing Date to but excluding
the Facility Termination Date, computed at .25% of the average daily aggregate
amount of the Aggregate Available Commitment from time to time in effect, to be
payable quarterly in arrears, within 5 days after the end of each quarter, and
on the Facility Termination Date.

     2.11 FACILITY FEE.  The Borrower agrees to pay to the Agent on the Closing
Date for the pro rata benefit of the Lenders a facility fee set forth in a fee
letter dated as of the Closing Date between the Borrower and the Agent.

     2.12 ADMINISTRATIVE FEES.  The Borrower agrees to pay to the Agent on the
Closing Date, for its own account, certain administrative fees set forth in a
fee letter dated as of the Closing Date between the Borrower and the Agent.

     2.13 VOLUNTARY CONVERSION OF ADVANCES.  The Borrower may on any Business 
Day, upon written notice (a


                                      -21-

<PAGE>


"Conversion/Continuation Notice") given to the Agent not later than 12:00 
noon, Los Angeles time, on the second Business Day before the date of the 
proposed conversion and subject to the provisions of Section 3.1(c), convert 
any Advance into an Advance of another Type; PROVIDED, HOWEVER, that, with 
respect to a conversion from a Fixed Rate Loan into a Reference Rate Loan, 
any such conversion shall be made on, and only on, the last day of the 
Interest Period for such Loan.  Each such notice of a conversion shall, 
within the restrictions specified above, specify (i) the Loan to be 
converted, (ii) the Type of Loan into which such Loan is to be converted and 
(iii) the requested date for such conversion.  Upon receipt of any such 
notice the Agent shall promptly notify each Lender thereof.  Any part of 
outstanding Fixed Rate Loans and Reference Rate Loans may be converted as 
provided herein, provided (a) no Loan may be converted into a Fixed Rate Loan 
after the date that is one month prior to the Facility Termination Date and 
(b) the Borrower shall not have the right to continue or convert to a Fixed 
Rate Loan if a Default shall have occurred and be continuing.  However, if 
the Borrower shall fail to give any required notices described above in this 
Section or if such continuation is not permitted pursuant to the preceding 
sentence, such Loans shall be automatically converted to Reference Rate Loans 
on the last day of such then-expiring Interest Period and shall be continued 
in Dollars or the Optional Currency in which last denominated.

     2.14 NOTICE OF BORROWING.  The Borrower shall give the Agent irrevocable
telephonic notice (promptly followed by written notice substantially in the form
of Exhibit D attached hereto) (which telephonic notice must be received by the
Agent prior to 10:30 a.m., Los Angeles time, on the proposed Borrowing Date or,
if all or any part of the Loans are requested to be made as Fixed Rate Loans or
Loans in an Optional Currency, three Business Days prior to each proposed
Borrowing Date) requesting that the Lenders make the Loans on the proposed
Borrowing Date and specifying (i) the aggregate amount of Loans requested to be
made (which must be in an aggregate amount equal to at least $1,000,000 (or the
Dollar Equivalent of such amount if made in an Optional Currency) or an integral
multiple of $100,000 (or the Dollar Equivalent of such amount if made in an
Optional Currency)) (or, if less, the then Available Commitment), (ii) subject
to Section 2.5, whether the Loans are (iii) if the Loans are to be entirely or
partly Fixed Rate Loans, the respective amounts of each such Type of Loan and
the respective lengths of the Interest Periods therefor and (iv) if the Loans
are to be partly or entirely Loans in an Optional Currency, the respective
amounts of each Optional Currency.  Each Loan in an Optional Currency must have
a Dollar Equivalent at least equal to $1,000,000 or the remaining balance of the
Available Commitment, if less.  On receipt of such telephonic notice, the Agent
shall promptly notify each Lender thereof no later than 10:30 a.m., Los Angeles
time, on the date of receipt of such telephonic notice.  On the proposed
Borrowing Date, not later 


                                      -22-

<PAGE>

than 1:00 p.m., Los Angeles time, each Lender shall make available to the 
Agent at its office specified in Section 15.1 such Lender's Commitment 
Percentage of the aggregate borrowing amount (as determined in accordance 
with Section 2.4) in immediately available funds and in Dollars or the 
Optional Currency requested.  Not later than 1:30 p.m., Los Angeles time, on 
the date of such Loans and upon fulfillment of the applicable conditions set 
forth in Section 4, the Agent shall make such Loans available to the Borrower 
in immediately available funds.  Each notice pursuant to this Section 2.14 
shall be irrevocable and binding on the Borrower.  The Agent may, in the 
absence of notification from any Lender that such Lender has not made its 
Commitment Percentage available to the Agent, on such date, credit the 
account of the Borrower on the books of such office of the Agent with the 
aggregate amount of Loans.

     2.15 COMMITMENT OBLIGATIONS.  Neither the Agent nor any Lender shall be
responsible for the obligation or Available Commitment of any other Lender
hereunder, nor will the failure of any Lender to comply with the terms of this
Agreement relieve any other Lender or the Borrower of their obligations under
this Agreement and the Notes.  Nothing herein shall be deemed to relieve any
Lender from its obligation to fulfill its Commitments hereunder or to prejudice
any rights which the Borrower may have against any Lender as a result of any
default by such Lender hereunder.

     2.16 INTEREST.  A Reference Rate Loan shall bear interest on the
outstanding principal amount thereof, for each day from and including the date
such Loan is made or is converted from a Fixed Rate Loan into a Reference Rate
Loan pursuant to Section 2.13 to (but not including) the date it becomes due or
is converted into a Fixed Rate Loan pursuant to Section 2.13 hereof, at a rate
per annum equal to the Reference Rate for such day.  Changes in the rate of
interest on any Loan maintained as a Reference Rate Loan will take effect
simultaneously with each change in the Reference Rate.  Each Fixed Rate Loan
shall bear interest from and including the first day of the Interest Period
applicable thereto to (but not including) the last day of such Interest Period
at the Fixed Rate determined as applicable to such Fixed Rate Loan.

     2.17 RATES APPLICABLE AFTER DEFAULT.  Notwithstanding anything to the
contrary contained herein, during the continuance of an Event of Default no Loan
may be made as, converted into or continued as a Fixed Rate Loan.  During the
continuance of an Event of Default each Loan shall bear interest at a rate per
annum equal to the Reference Rate plus 2% per annum.  All such interest shall be
payable on demand of the Agent.

     2.18 METHOD OF PAYMENT.  All payments of the Obligations hereunder shall be
made, without setoff, deduction, or counterclaim, in immediately available funds
in Dollars or the 


                                      -23-

<PAGE>


Optional Currency in which the Loan was made to the Agent at the address 
specified pursuant to Article 15, or at any other Applicable Lending Office 
of the Agent specified in writing by the Agent to the Borrower, by 2:00 p.m., 
Los Angeles time, on the date when due and shall be applied ratably by the 
Agent among the Lenders.  Each payment delivered to the Agent for the account 
of any Lender shall be delivered promptly by the Agent to such Lender in the 
same type of funds that the Agent received at its address specified pursuant 
to Article 15 or at any Applicable Lending Office specified in a notice 
received by the Agent from such Lender.  The Agent is hereby authorized (but 
not obligated) to charge the accounts of the Borrower maintained with Sanwa 
for each payment of principal, interest and fees as it becomes due hereunder.

     2.19 TELEPHONIC NOTICES.  The Borrower hereby authorizes the Lenders and
the Agent to borrow Loans and to convert or continue Loans and effect selections
of Types of Loans based on telephonic notices made by any Person or Persons the
Agent or any Lender in good faith believes to be acting on behalf of the
Borrower.  The Borrower agrees to deliver promptly to the Agent a written
confirmation, if such confirmation is requested by the Agent or any Lender, of
each telephonic notice signed by an Authorized Officer.  If the written
confirmation differs in any material respect from the action taken by the Agent
and the Lenders, the records of the Agent and the Lenders shall govern absent
manifest error.

     2.20 INTEREST PAYMENT DATES; INTEREST AND FEE BASIS.  Interest accrued on
each Reference Rate Loan shall be payable in arrears on the first Business Day
of each calendar month, commencing with the first such date to occur after the
Closing Date, on any date on which Reference Rate Loan is prepaid, whether due
to acceleration or otherwise, and at maturity.  Interest accrued on that portion
of the outstanding principal amount of any Reference Rate Loan converted into a
Fixed Rate Loan on a day other than an interest payment date shall be payable on
the date of conversion.  Interest accrued on each Fixed Rate Loan shall be
payable on the last day of its applicable Interest Period, on any date on which
the Fixed Rate Loan is prepaid, whether by acceleration or otherwise, and at
maturity.

     Interest on Fixed Rate Loans and fees shall be calculated for actual days
elapsed on the basis of a 360-day year and interest on Reference Rate Loans
shall be calculated for actual days elapsed on the basis of 365-day year. 
Interest shall be payable for the day a Loan is made but not for the day of any
payment on the amount paid if payment is received prior to 2:00 p.m., Los
Angeles time, at the place of payment.  Whenever any payment to be made
hereunder shall be stated to be due on a day that is not a Business Day, such
payment shall be made on the next succeeding Business Day, and such extension of
time shall in such case be included in the computation of payment of 


                                      -24-

<PAGE>

interest; PROVIDED, HOWEVER, that, if such extension would cause any payment 
of interest on or principal of any Fixed Rate Loan to be made in the next 
following calendar month, then such payment shall instead be made on the next 
preceding Business Day, and such shortened time shall in such case be used in 
the computation of payment of interest.

     2.21 NOTIFICATION OF LOAN, INTEREST RATES, PREPAYMENTS AND COMMITMENT
REDUCTIONS.  Promptly after receipt thereof, the Agent will notify each Lender
of the contents of a borrowing notice, Conversion/Continuation Notice and
repayment notice received by it hereunder.  The Agent will notify each Lender of
the interest rate applicable to each Loan promptly upon determination of such
interest rate and will give each Lender prompt notice of each change in the
Reference Rate.

     Each determination of an interest rate by the Agent pursuant to any
provision of this Agreement shall be conclusive and binding on the Borrower and
the Lenders in the absence of manifest error.

     2.22 APPLICABLE LENDING OFFICES.  Subject to Section 3.3, each Lender 
may book its Loans at any Applicable Lending Office selected by such Lender 
and may change its Applicable Lending Office from time to time.  All terms of 
this Agreement shall apply to any such Applicable Lending Office and the 
Notes shall be deemed held by each Lender for the benefit of such Applicable 
Lending Office. Each Lender may, by written or telex notice to the Agent and 
the Borrower, designate an Applicable Lending Office through which the Loans 
will be made by it and for whose account Loan payments are to be made.

     2.23 NON-RECEIPT OF FUNDS BY THE AGENT.  Unless the Borrower or a Lender,
as the case may be, notifies the Agent prior to the date on which it is
scheduled to make payment to the Agent of (i) in the case of a Lender, the
proceeds of a Loan or (ii) in the case of the Borrower, a payment of principal,
interest or fees to the Agent for the account of the Lenders, that it does not
intend to make such payment, the Agent may assume that such payment has been
made.  The Agent may, but shall not be obligated to, make the amount of such
payment available to the intended recipient in reliance upon such assumption. 
If such Lender or the Borrower, as the case may be, has not in fact made such
payment to the Agent, the recipient of such payment shall, on demand by the
Agent, repay to the Agent the amount so made available together with interest
thereon in respect of each day during the period commencing on the date such
amount was so made available by the Agent until the date the Agent recovers such
amount at a rate per annum equal to (a) in the case of payment by a Lender, the
overnight federal funds effective rate (as published by the Board of Governors
of the Federal Reserve System as in effect from time to time) for such day or
(b) in the case of payment by the Borrower, the interest rate applicable to the
relevant Loan.

     2.24  WITHHOLDING TAX EXEMPTION.  Subject to Section 3.3, at least five 
Business Days prior to the first date on which interest or fees are payable 
hereunder for the account of any Lender, each Lender that is not incorporated 
under the laws of the United States of America, or a state thereof, agrees 
that it will deliver to the Borrower and the Agent two duly completed copies 
of United States Internal Revenue Service Form 1001 or 4224, certifying in 
either case that such Lender is entitled to receive payments under this 
Agreement and the Notes without deduction or withholding of any United States 
federal income taxes.  Each Lender which so delivers a Form 1001 or 4224 
further undertakes to deliver to the Borrower and the Agent two additional 
copies of such form (or a successor form) on or before the date that such 
form expires (currently, three successive calendar years for Form 1001 and 
one calendar year for Form 4224) or becomes obsolete or after the occurrence 
of any event requiring a change in the most recent forms so delivered by it, 
and such amendments thereto or extensions or renewals thereof as may be 
reasonably requested by the Borrower or the Agent, in each case certifying 
that such Lender is entitled to receive payments under this Agreement and the 
Notes without deduction or withholding of any United States federal income 
taxes, unless an event (including without limitation any change in treaty, 
law or regulation) has occurred prior to the date on which any such delivery 
would otherwise be required which renders all such forms inapplicable or 
which would prevent such Lender from duly completing and delivering any such 
form with respect to it and such Lender advises the Borrower and the Agent 
that it is not capable of receiving payments without any deduction or 
withholding of United States federal income tax.

     2.25  OPTIONAL PREPAYMENT.  The Borrower may at any time and from time 
to time, prepay the Loans, in whole or in part, without premium or penalty 
(except amounts required by Section 3.1), upon at least three Business Days' 
irrevocable written notice, in the case of Fixed Rate Loans, and upon at 
least one Business Day's irrevocable written notice, in the case of Reference 
Rate Loans, from the Borrower to the Agent, specifying the date and amount of 
prepayment and whether the prepayment is of Fixed Rate Loans, Reference Rate 
Loans or a combination thereof, the amount allocable to each.  Any prepayment 
of a Fixed Rate Loan on a day other than the last day of an Interest Period 
applicable thereto shall also be subject to the payment of amounts due under 
Section 3.1 hereof.  Upon receipt of any such notice from the Borrower, the 
Agent shall promptly notify each Lender thereof.  If any such notice is 
given, the amount specified in such notice shall be due and payable by the 
Borrower on the date specified therein, together with accrued interest to 
such date on the amount prepaid.  Partial prepayments of Loans shall be in an 
aggregate principal amount of $1,000,000 (or the Dollar Equivalent thereof if 
denominated in an Optional Currency) or in increments of $100,000 above such 
amount.  Optional prepayments shall be applied as directed by 


                                      -26-

<PAGE>


the Borrower and, in the absence of such direction, as the Agent shall 
determine.

     2.26  OPTIONAL CURRENCY DOLLAR EQUIVALENT.  For all purposes of this 
Agreement, the amount in one currency which shall be equivalent on any 
particular date to a specified amount in another currency shall be that 
amount (as conclusively ascertained by the Agent absent manifest error) in 
the first currency which is or could be purchased by the Agent (in accordance 
with its normal banking practices) with such specified amount in the second 
currency in the foreign currency deposit markets for delivery on such date at 
the spot rate of exchange prevailing at or about 11:00 a.m., Los Angeles 
time, on such date.

     In the event that any portion of the funds available under the terms of 
this Agreement is denominated in one or more Optional Currencies, the Dollar 
Equivalent of such portion of the funds shall be calculated pursuant to the 
above paragraph by the Agent at the time the Borrower request any Loan or 
Letter of Credit and otherwise no less frequently that once per week.  The 
amount so determined shall then be added to the amount already outstanding in 
Dollars for the purpose of determining the remaining Aggregate Available 
Commitment and any required repayments hereunder.

     2.27  MANDATORY PREPAYMENTS.

     (i)   If at any time the aggregate principal amount of all Loans 
outstanding (including Loans in any Optional Currency calculated at the 
Dollar Equivalent thereof), the aggregate Letter of Credit Amount of all 
Letters of Credit outstanding and the aggregate amount of unreimbursed 
drawings under all Letters of Credit shall exceed the lesser of (a) the 
Aggregate Commitment and (b) the Borrowing Base, whether as a result of 
fluctuations in currency exchange rates or otherwise, the Borrower shall pay 
immediately upon demand made by the Agent all amounts (calculated at the 
Dollar Equivalent, if applicable) required in order to reduce such amounts 
outstanding to the lesser of (a) the Aggregate Commitment and (b) the 
Borrowing Base, and if no Loans are then outstanding, shall deposit with the 
Agent cash collateral in an amount equal to the amount by which the aggregate 
Letter of Credit Amounts of all Letters of Credit outstanding exceeds the 
lesser of (a) the Aggregate Commitment and (b) the Borrowing Base.  If any 
such prepayment would result in the Borrower being obligated to pay 
breakfunding costs under Section 3.1(i), the Borrower may elect to deposit 
such prepayment amounts in a cash collateral account with the Agent (for the 
benefit of the Lenders), which amounts the Agent shall apply to reduce 
outstanding Loans at the end of relevant Interest Periods.

     (ii) If at any time the aggregate principal amount of the outstanding 
Loans (calculating all amounts denominated in 


                                      -27-

<PAGE>


Optional Currencies at their Dollar Equivalent) extended in Optional 
Currencies shall exceed $10,000,000, whether as a result of fluctuations in 
currency exchange rates or otherwise, the Borrower shall pay immediately upon 
demand by the Agent all amounts required in order to reduce such amount 
outstanding to $10,000,000 (or the Dollar Equivalent of Loans outstanding in 
Optional Currencies).  If any such prepayment would result in the Borrower 
being obligated to pay breakfunding costs under Section 3.1(i), the Borrower 
may elect to deposit such prepayment amounts in a cash collateral account 
with the Agent (for the benefit of the Lenders), which amounts the Agent 
shall apply to reduce outstanding Loans at the end of relevant Interest 
Periods.

     (iii)  If at any time the aggregate Letter of Credit Amount of all
Letters of Credit outstanding and the aggregate amount of unreimbursed drawings
under all Letters of Credit shall exceed $8,000,000 for whatever reason, the
Borrower shall immediately deposit with the Agent cash collateral in an amount
equal to the amount by which the aggregate Letter of Credit Amount of all
Letters of Credit outstanding and any aggregate amount of unreimbursed drawings
under all Letters of Credit shall exceed $8,000,000.  If any such prepayment
would result in the Borrower being obligated to pay breakfunding costs under
Section 3.1(i), the Borrower may elect to deposit such prepayment amounts in a
cash collateral account with the Agent (for the benefit of the Lenders), which
amounts the Agent shall apply to reduce outstanding Loans at the end of 
relevant Interest Periods.

     (iv)   Upon a sale, or a combination of sales, lease transfer or other
disposition of the assets of the Borrower (other than sales in the ordinary
course of business which ordinary course shall include, among other things, the
purchase and sale of access switches and circuits) which results in receipts by
the Borrower in an aggregate amount equal to at least $2,000,000 of either (1)
cash proceeds and/or (2) repayment of any Debt owing to the Borrower resulting
from any such sale or combination of sale of assets, the Borrower shall prepay
the Loans in amount equal to 100% of such cash proceeds or Debt repaid (net of
reasonable and customary costs of sale and related income tax expense) in excess
of $2,000,000.  All such prepayments shall be applied in accordance with Section
2.28.

     2.28 APPLICATION OF REPAYMENTS.  All repayments of principal made pursuant
to Section 2.27 (except as expressly set forth in Sections 2.27(i), (ii) and
(iii)) shall be applied, in the absence of instruction by the Borrower, first to
the principal of Reference Rate Loans and then to the principal of Fixed Rate
Loans.  Each partial repayment shall be allocated among the Lenders in
proportion, as nearly as practicable, to their respective Commitment
Percentages, with adjustments to the 


                                      -28-

<PAGE>

extent practicable, to equalize any prior repayments not exactly in 
proportion.

     Notwithstanding the rights given to the Borrower pursuant to California
Civil Code Sections 1479 and 2822 or equivalent provisions in the laws in the
State of California, to designate how payments will be applied, the Borrower
hereby waives such rights and the Agent shall have the right in its sole
discretion, other than as specifically set forth herein, to determine the order
and method of application of payments to outstanding Obligations and to revise
such application prospectively or retroactively at its discretion.

     2.29 INTEREST LIMITATION.  Notwithstanding any other term of this Agreement
or any Note or any other Loan Document or any other document referred to herein
or therein, the maximum amount of interest which may be charged to or collected
from any person liable hereunder or under any Note by the Lenders shall be
absolutely limited to, and shall in no event exceed, the maximum amount of
interest which could lawfully be charged or collected under applicable law,
except that the maximum of all amounts constituting interest under applicable
law, howsoever computed shall never exceed as to any Person liable therefor such
lawful maximum, in any term of this Agreement, any Note, any Loan Document or
any other document referred to herein or therein which could be construed as
providing for interest in excess of such lawful maximum shall be and hereby is
made expressly subject to and modified by the provisions of this Section.

                               CHANGE IN CIRCUMSTANCES


     3.1  YIELD PROTECTION.

          (i)  If any repayment of principal of, or conversion of, any Fixed
Rate Loan is made other than on the last day of an Interest Period therefor, as
a result of a prepayment, payment or conversion, or an acceleration of the
maturity of the Loan pursuant to Section 10, or for any other reason, or if the
Borrower shall fail to borrow a Fixed Rate Loan after requesting one, then the
Borrower shall, upon demand by the Agent pay to the Lenders any amounts required
to compensate them for any additional losses, costs or expenses that they may
reasonably incur as a result of such repayment, conversion or failure to borrow,
including any loss (including loss of anticipated profits), cost or expense
incurred by reason of the liquidation or reemployment of deposits or other funds
acquired by a Lender to fund or maintain such Fixed Rate Loan.


                                      -29-

<PAGE>


        (ii)   Subject to Section 3.3, if, due to either (a) the introduction 
of or any change in or in the interpretation of any Governmental Rule or (b) 
the compliance by the Lenders with any Governmental Rule (whether or not 
having the force of law), there is any increase in the cost to the Lenders of 
agreeing to make, making, funding or maintaining any Fixed Rate Loan, then 
the Borrower shall from time to time, upon written demand by the Agent, pay 
to the Agent additional amounts sufficient to compensate the Lenders for such 
increased cost. A certificate as to the amount of such increased cost, 
submitted to the Borrower by the Agent, shall be conclusive and binding for 
all purposes, absent manifest error.

        (iii)  Subject to Section 3.3, notwithstanding any other provision of
this Agreement, if the introduction of or any change in or in the interpretation
of any Governmental Rule makes it unlawful, or any Governmental Person asserts
that it is unlawful, for any Lender to perform its obligations hereunder to make
Fixed Rate Loans or to continue to fund or maintain Fixed Rate Loans hereunder,
then, on notice thereof and demand therefor by the Agent to the Borrower, (a)
the obligation of such Lender to make Fixed Rate Loans and to convert Reference
Rate Loans into Fixed Rate Loans shall terminate and (b) the Borrower shall
forthwith prepay in full that portion of the Fixed Rate Loans of such Lender
then outstanding, together with interest accrued thereon, unless the Borrower,
within five Business Days of such notice and demand, converts such portion of
Fixed Rate Loans into Reference Rate Loans in accordance with Section 2.13.

         (iv)  Subject to Section 3.3, if, with respect to any Fixed Rate Loan,
the Agent notifies the Borrower that the Fixed Rate for such Loan will not
adequately reflect the cost to one or more Lenders (as determined by such
Lender(s) in good faith on the basis of market conditions then in effect) of
making, funding or maintaining such Loan, then (a) such Loan will automatically,
on the last day of the then existing Interest Period therefor, convert into a
Reference Rate Loan and (b) the obligation of the affected Lender to make, or to
convert Reference Rate Loans into Fixed Rate Loans shall be suspended until the
Agent notifies the Borrower that the circumstances causing such suspension no
longer exist.

     3.2  TAXES.  Subject to Section 3.3, all payments by or on behalf of the
Borrower hereunder shall be made without set-off or counterclaim and in such
amounts as may be necessary in order that all such payments (after deduction or
withholding for or on account of any present or future taxes, levies, imposts,
duties or other charges of whatsoever nature imposed by any Governmental Person,
other than any tax on or measured by the overall net income of the Agent or a
Lender pursuant to the income tax laws of the United States, the jurisdiction
where the Agent's or such Lender's principal office is located or any political
subdivision thereof (collectively, the "Taxes")) shall 


                                      -30-

<PAGE>

not be less than the amounts otherwise specified to be paid hereunder.  A 
certificate as to any additional amounts payable to the Agent or a Lender 
hereunder submitted to the Borrower by the Agent shall show in reasonable 
detail the amount payable to the Agent or a Lender and the calculations used 
to determine in good faith such amount and shall be conclusive absent 
manifest error.  Any amounts payable by the Borrower hereunder with respect 
to past payments shall be due within ten days following receipt by the 
Borrower of such certificate from the Agent; and such amounts payable with 
respect to future payments shall be due concurrently with such future 
payments.  With respect to each deduction or withholding for or on account of 
any Taxes, the Borrower shall promptly furnish to the Agent such 
certificates, receipts and other documents as may be required (in the 
reasonable judgment of the Agent) to establish any tax credit to which a 
Lender may be entitled.  The agreements and obligations of the Borrower under 
this paragraph shall survive the payment in full of the Loans.

     3.3  REPLACEMENT OF LENDERS.  If the Borrower is obligated to pay to any
Lender (other than the Agent) any amount under Sections 3.1 or 3.2 or if any
Lender requests that its Fixed Rate Loans be converted into Reference Rate Loans
pursuant to Section 3.1, the Borrower may, so long as no Default or Event of
Default then exists, replace such Lender with another Lender which meets all of
the qualifications of being an Eligible Assignee and which complies with the
provisions of Section 14.3.  The Borrower may, in the absence of replacing any
such Lender, request that such Lender designate another of its existing
facilities as the Applicable Lending Office for making Fixed Rate Loans or take
other reasonable action, if such designation or other action would avoid the
need for, or reduce the amount of, compensation to be paid by the Borrower
hereunder to such Lender.  No Lender will be required to take any action which
in its good faith judgment is disadvantageous to such Lender.

                                      ARTICLE 5

                            REPRESENTATIONS AND WARRANTIES

     The Borrower represents and warrants to the Lenders that:

     5.1  AUTHORIZATION.  The execution, delivery and performance by the
Borrower of the Loan Documents to which the Borrower is a party are within the
Borrower's corporate powers, have been duly authorized by all necessary
corporate action and do not contravene any applicable law, rule, regulation or
order or any contractual restriction binding on or affecting the Borrower or its
Subsidiaries.

     5.2  ENFORCEABILITY.  Each Loan Document to which the Borrower is a party
is the legal, valid and binding obligation of the Borrower, enforceable against
the Borrower in accordance with its terms, except as the enforceability thereof
may be limited by bankruptcy, insolvency, reorganization, moratorium or other
similar laws affecting creditors' rights generally.

     5.3  USE OF PROCEEDS.  The Borrower will use the proceeds of the Loans
solely as set forth in Section 7.2.  No action has been taken or is currently
planned by the Borrower, or any agent acting on its behalf, which would cause
this Agreement or the Notes to violate Regulation U or any other regulation of
the Board of Governors of the Federal Reserve System or to violate the
Securities and Exchange Act of 1934, in each case as in effect now or as the
same may hereafter be in effect.  The Borrower is not engaged in the business of
extending credit for the purpose of purchasing or carrying margin stock as one
of its important activities and none of the proceeds of the Loans or Letters of
Credit will be used directly or indirectly for such purpose.

     5.4  LITIGATION.  Except as disclosed in writing to the Agent, there is no
litigation, tax claim, proceeding, arbitration or dispute pending, or, to the
best knowledge of the Borrower, threatened against or affecting the Borrower or
its Property, an adverse determination in which could have a Material Adverse
Effect.

     5.5  FINANCIAL STATEMENTS.  The Consolidated financial statements of the
Borrower dated December 31, 1996 and June 30, 1997, copies of which have been
delivered to the Lenders, fairly and accurately reflect the financial condition
of the Borrower and its Subsidiaries as of such date (except to the extent that
the interim financial statements are subject to year-end adjustments and to the
inclusion of additional footnotes), and since such date there has been no
Material Adverse Effect.

     5.6  TAXES.  The Borrower and each Subsidiary have filed all tax returns
and reports required to be filed and have paid

                                      -34-

<PAGE>

all applicable federal, state and local franchise and income taxes which are 
set forth on such return.

     5.7  SUBSIDIARIES.  Schedule 2 hereto contains an accurate list of all of
the presently existing Subsidiaries of the Borrower, setting forth their
respective jurisdictions of incorporation or organization and the percentage of
their respective capital stock or ownership interests owned by the Borrower or
other Subsidiaries.  All of the issued and outstanding shares of capital stock
of such Subsidiaries have been duly authorized and issued and are fully paid and
non-assessable.

     5.8  ERISA.  There are no Unfunded Liabilities of the Borrower.  Each
Single Employer Plan complies in all material respects with all applicable
requirements of law and regulations, except to the extent that the failure to
comply therewith does not have a Material Adverse Effect.  No Reportable Event
has occurred with respect to any Single Employer Plan, except to the extent that
such Reportable Event has no Material Adverse Effect.  Neither the Borrower nor
any Subsidiary (a) is a party to any Multiemployer Plan or (b) has withdrawn
from any Multiemployer Plan, except to the extent such actions do not have a
Material Adverse Effect.

     5.9  ACCURACY OF INFORMATION.  No written information, exhibit or report
furnished by the Borrower or any of its Subsidiaries to the Agent or to any
Lender in connection with the negotiation of, or compliance with, the Loan
Documents (including projected financial information) contain any material
misstatement of fact or omit to state a material fact or any fact necessary to
make the statements contained therein not misleading in any material respect. 
All projected financial information which has been furnished by or on behalf of
the Borrower or any Subsidiary to the Agent or any Lender was, at the time so
furnished, believed by the Borrower to have been prepared in a reasonable manner
and based on reasonable assumptions with respect to the Borrower's business,
provided that no representation is made by the Borrower that the future results
of the Borrower will equal those set forth in such projected financial
information.

     5.10 ORGANIZATION AND EXISTENCE.  The Borrower is duly organized, validly
existing and in good standing under the laws of the State of Delaware, and it
has the corporate power and authority, and the legal right, to own and operate
its Properties and to conduct the business in which it is currently engaged and
in which it proposes to be engaged after the Closing Date and is duly qualified
as a foreign entity and in good standing under the laws of each jurisdiction
where its ownership, lease or operation of Property or the conduct of its
business requires such qualification except to the extent that the failure to
comply thereunder could not, in the aggregate, reasonably be expected to have a
Material Adverse Effect and is

                                     -35-

<PAGE>

in compliance with all Requirements of Law except to the extent that the 
failure to comply therewith could not, in the aggregate, reasonably be 
expected to have a Material Adverse Effect.

     5.11 CONSENTS.  No consent or authorization of, or filing with or other act
by or in respect of, any Governmental Authority, or any other Person is required
in connection with the Loans hereunder or with the execution, delivery,
performance, validity or enforceability of this Agreement, the Notes or the
other Loan Documents.  The execution, delivery and performance of this
Agreement, the Notes and the other Loan Documents, the Loans, the Letters of
Credit and the use of the proceeds thereof will not violate any Requirement of
Law or contractual obligations of the Borrower or any of its Subsidiaries which
could be reasonably expected to have a Material Adverse Effect and will not
result in, or require, the creation or imposition of any Lien on any of its or
its Properties or revenues pursuant to any such Requirement of Law or
contractual obligation, except pursuant to the Loan Documents or otherwise as
permitted hereunder, which Lien could reasonably be expected to have a Material
Adverse Effect.

     5.12 INTELLECTUAL PROPERTY.  The Borrower and each of its Subsidiaries
owns, or is licensed to use, all trademarks, tradenames, patents, copyrights,
material permits, licenses or other intangibles necessary for the conduct of its
business as currently conducted without conflict with the rights of others,
except to the extent that the failure to own or license such property could not
reasonably be expected to have a Material Adverse Effect.

     5.13 DEFAULT.  There exists no Default or Event of Default.

     5.14 NATURE OF BUSINESS.  Neither the Borrower nor any of its subsidiaries
is engaged in any material business other than as set forth in the Borrower's
registration statement on Form S-1, Registration No. 333-21325, as declared
effective by the SEC on June 12, 1997.

     5.15 RANKING OF LOANS.  This Agreement and the other Loan Documents to
which the Borrower is party, when executed, and the Loans, when borrowed are and
will be the direct and general obligations of the Borrower.  The Borrower's
Obligations hereunder and thereunder will rank at least PARI PASSU in priority
of payment with all other senior Debt, except to the extent otherwise permitted
hereunder.

     5.16 INVESTMENT COMPANY ACTS; OTHER REGULATIONS.  Neither the Borrower nor
any of its Subsidiaries is an "investment company," or a company "controlled" by
an "investment company," within the meaning of the Investment Company Act of
1940, as amended.

                                     -36

of grace provided with respect thereto, or the Borrower shall default in the
observance or performance of any other agreement contained in any such bonds,

                         ACCELERATION, WAIVERS AND AMENDMENTS


     10.1 ACCELERATION.  If any Event of Default described in Section 9.4 occurs
with respect to the Borrower, the obligations of the Lenders to make Loans and
issue and participate in new Letters of Credit hereunder shall automatically
terminate and the Obligations shall immediately become due and payable without
any election or action on the part of the Agent or any Lender.  If any other
Event of Default occurs, the Required Lenders may terminate or suspend the
obligations of the Lenders to make Loans and issue and participate in new
Letters of Credit hereunder, or declare the Obligations to be due and payable,
or both, whereupon the Obligations shall become immediately due and payable,
without presentment, demand, protest or notice of any kind, all of which the
Borrower hereby expressly waives.  All Lenders' funded and unfunded obligations
hereunder shall be adjusted on a pro rata basis consistent with its respective
Commitment Percentages.

                                     -47-
<PAGE>

     10.2 CASH COLLATERAL.  To the extent that any Letters of Credit are
outstanding at the time of any Event of Default, the Borrower shall deliver to
the Agent, for the benefit of the Lenders, a cash collateral deposit in an
amount equal to the aggregate Letter of Credit Amount for all Letters of Credit
then outstanding.

     10.3 ADDITIONAL REMEDIES.  The rights, powers and remedies given to the
Agent and the Lenders hereunder shall be cumulative and not alternative and
shall be in addition to all rights, powers and remedies given to the Agent and
the Lenders by law against the Borrower or any other Person, including but not
limited to any Lender's right of setoff or banker's lien.

     10.4 AMENDMENTS.  Subject to the provisions of this Article 10, the
Required Lenders (or the Agent with the consent in writing of the Required
Lenders) and the Borrower may enter into agreements supplemental hereto for the
purpose of adding or modifying any provisions to the Loan Documents or changing
in any manner the rights of the Lenders or the Borrower hereunder or waiving any
Default hereunder; provided, however, that no such supplemental agreement shall,
without the consent of each Lender affected thereby:

     (i)       Extend the maturity of any Loan or Note or forgive all or any 
               portion of the principal amount thereof, or reduce the rate or 
               extend the time of payment of interest or fees thereon.

     (ii)      Reduce the percentage specified in the definition of Required 
               Lenders.

     (iii)     Increase the amount of the Commitment of any Lender hereunder or
               permit the Borrower to assign its rights under this Agreement.

     (iv)      Release any of the Property pledged under the Loan Documents.

     (v)       Amend this Section 10.4.

No amendment of any provision of this Agreement relating to the Agent shall be
effective without the written consent of the Agent.  The Agent may waive payment
of the fees required under Section 14.3(ii) without obtaining the consent of any
other party to this Agreement.

     10.5 PRESERVATION OF RIGHTS.  No delay or omission of the Lenders or the
Agent to exercise any right under the Loan Documents shall impair such right or
be construed to be a waiver of any Default or an acquiescence therein, and the
making of a Loan notwithstanding the existence of a Default or the inability of
the Borrower to satisfy the conditions precedent to such Loan shall not
constitute any waiver or acquiescence.  Any single or

                                      -48-

<PAGE>

partial exercise of any such right shall not preclude other or further 
exercise thereof or the exercise of any other right, and no waiver, amendment 
or other variation of the terms, conditions or provisions of the Loan 
Documents whatsoever shall be valid unless in writing signed by the Lenders 
required pursuant to Section 10.4, and then only to the extent in such 
writing specifically set forth.  All remedies contained in the Loan Documents 
or by law afforded shall be cumulative and all shall be available to the 
Agent and the Lenders until the Obligations have been paid in full.

                                      ARTICLE 11

                                  GENERAL PROVISIONS


     11.1      SURVIVAL OF REPRESENTATIONS.  All representations and 
warranties of the Borrower contained in this Agreement shall survive delivery 
of the Notes and the making of the Loans and issuance of the Letters of 
Credit herein contemplated.

     11.2      GOVERNMENTAL REGULATION.  Anything contained in this Agreement 
to the contrary notwithstanding, no Lender shall be obligated to extend 
credit to the Borrower in violation of any limitation or prohibition provided 
by any applicable statute or regulation.

     11.3      HEADINGS.  Section headings in the Loan Documents are for 
convenience of reference only, and shall not govern the interpretation of any 
of the provisions of the Loan Documents.

     11.4      ENTIRE AGREEMENT.  The Loan Documents embody the entire 
agreement and understanding among the Borrower, the Agent and the Lenders and 
supersede all prior agreements and understandings among the Borrower, the 
Agent and the Lenders relating to the subject matter thereof.

     11.5      SEVERAL OBLIGATIONS; BENEFITS OF THIS AGREEMENT.  The 
respective obligations of the Lenders hereunder are several and not joint and 
no Lender shall be the partner or agent of any other (except to the extent to 
which the Agent is authorized to act as such).  The failure of any Lender to 
perform any of its obligations hereunder shall not relieve any other Lender 
from any of its obligations hereunder.  This Agreement shall not be construed 
so as to confer any right or benefit upon any Person other than the parties 
to this Agreement and its respective successors and assigns.

     11.6      EXPENSES; INDEMNIFICATION.  The Borrower shall reimburse the 
Agent for any costs, internal charges and out-of-pocket expenses (including 
reasonable attorneys' fees and time charges of attorneys for the Agent and 
audit expenses), paid or incurred by the Agent in connection with the

                                     -49-

<PAGE>

negotiation, documentation and syndication of this Agreement.  The Borrower 
shall also reimburse the Agent and each Lender for any costs, internal 
charges and out-of-pocket expenses (including reasonable attorneys' fees and 
time charges of attorneys for the Agent and each Lender) paid or incurred by 
the Agent or any Lender in connection with the collection and enforcement of 
the Loan Documents.  The Borrower further agrees to indemnify the Agent and 
each Lender, its directors, officers and employees against all losses, 
claims, damages, penalties, judgments, liabilities and expenses (including, 
without limitation, all expenses of litigation or preparation therefor 
whether or not the Agent or any Lender is a party thereto) which any of them 
may pay or incur arising out of or relating to this Agreement, the other Loan 
Documents, the transactions contemplated hereby or the direct or indirect 
application or proposed application of the proceeds of any Loan or Letter of 
Credit hereunder, provided that no Person shall have the right to be 
indemnified hereunder for such Person's own gross negligence or willful 
misconduct as determined by a court of competent jurisdiction.

     11.7      NUMBERS OF DOCUMENTS.  All statements, notices, closing 
documents, and requests hereunder shall be furnished to the Agent with 
sufficient counterparts so that the Agent may furnish one to each of the 
Lenders.

     11.8      SEVERABILITY OF PROVISIONS.  Any provision in any Loan 
Document that is held to be inoperative, unenforceable, or invalid in any 
jurisdiction shall, as to that jurisdiction, be inoperative, unenforceable, 
or invalid without affecting the remaining provisions in that jurisdiction or 
the operation, enforceability, or validity of that provision in any other 
jurisdiction, and to this end the provisions of all Loan Documents are 
declared to be severable.

     11.9      NONLIABILITY OF LENDERS.  The relationship between the 
Borrower and the Lenders and the Agent shall be solely that of borrower and 
lender.  Neither the Agent nor any Lender shall have any fiduciary 
responsibilities to the Borrower.  Neither the Agent nor any Lender 
undertakes any responsibility to the Borrower to review or inform the 
Borrower of any matter in connection with any phase of the Borrower's 
business or operations.

     11.10     CHOICE OF LAW.  THE LOAN DOCUMENTS (OTHER THAN THOSE CONTAINING A
CONTRARY EXPRESS CHOICE OF LAW PROVISION) SHALL BE CONSTRUED IN ACCORDANCE WITH
THE INTERNAL LAWS (AND NOT THE LAW OF CONFLICTS) OF THE STATE OF CALIFORNIA, BUT
GIVING EFFECT TO FEDERAL LAWS APPLICABLE TO NATIONAL BANKS.

     11.11     CONSENT TO JURISDICTION.  SUBJECT TO SECTION 11.15 BELOW, THE
BORROWER HEREBY IRREVOCABLY SUBMITS TO THE NON-EXCLUSIVE JURISDICTION OF ANY
UNITED STATES FEDERAL OR CALIFORNIA STATE COURT SITTING IN LOS ANGELES IN ANY
ACTION OR

PROCEEDING MAY BE HEARD AND DETERMINED IN ANY SUCH COURT AND IRREVOCABLY 
WAIVES ANY OBJECTION IT MAY NOW OR HEREAFTER HAVE AS TO THE VENUE OF ANY SUCH 
SUIT, ACTION OR PROCEEDING BROUGHT IN SUCH A COURT OR THAT SUCH COURT IS AN 
INCONVENIENT FORUM SUBJECT TO SECTION 11.15 BELOW, NOTHING HEREIN SHALL LIMIT 
THE RIGHT OF THE AGENT OR ANY LENDER TO BRING PROCEEDINGS AGAINST THE 
BORROWER IN THE COURTS OF ANY OTHER JURISDICTION SUBJECT TO SECTION 11.15 
BELOW.  ANY JUDICIAL PROCEEDING BY THE BORROWER AGAINST THE AGENT OR ANY 
LENDER OR ANY AFFILIATE OF THE AGENT OR ANY LENDER INVOLVING, DIRECTLY OR 
INDIRECTLY, ANY MATTER IN ANY WAY ARISING OUT OF, RELATED TO, OR CONNECTED 
WITH ANY LOAN DOCUMENT SHALL BE BROUGHT ONLY IN A COURT IN LOS ANGELES, 
CALIFORNIA.

     11.12     WAIVER OF JURY TRIAL.  SUBJECT TO SECTION 11.15 BELOW, THE
BORROWER, THE AGENT AND EACH LENDER HEREBY WAIVE TRIAL BY JURY IN ANY JUDICIAL

TORT, CONTRACT OR OTHERWISE) IN ANY WAY ARISING OUT OF, RELATED TO, OR CONNECTED
WITH ANY LOAN DOCUMENT OR THE RELATIONSHIP ESTABLISHED THEREUNDER.

     11.13     INTEGRATION CLAUSE.  Except for documents and instruments
specifically referenced herein, this Agreement constitutes the entire agreement
among the Agent, the Lenders and the Borrower regarding the Loans and Letters of
Credit and all prior communications verbal or written between the Borrower and
the Agent or any Lender shall be of no further effect or evidentiary value.

     11.14     CONFIDENTIALITY.  The Lenders shall take normal and reasonable
precautions to maintain the confidentiality of all non-public information
obtained pursuant to the requirements of this Agreement which has been
identified as such by the Borrower but may, in any event, make disclosures (i)
reasonably required by any bona fide transferee, assignee or participant in
connection with the contemplated transfer or assignment of any of the
Commitments or Loans or participations therein or participations in Letters of
Credit, so long as such transferee, assignee or participant agrees to be bound
by the terms hereof or (ii) as required or requested by any governmental agency
or representative thereof or as required pursuant to any legal process or (iii)
to its attorneys and accountants or (iv) as required by law or (v) in connection
with litigation involving any Lender.

     11.15     DISPUTE RESOLUTION.  It is understood and agreed that upon the
request of any party hereto any dispute, claim, or controversy of any kind,
whether in contract or in tort, statutory or common law, legal or equitable now
existing or hereinafter arising out of, pertaining to or in connection with this
Agreement or the other Loan Documents, or any related

                                     -51-

<PAGE>

agreements, documents, or instruments, shall be resolved through final and 
binding arbitration administered by Judicial Arbitration & Mediation 
Services, Inc. ("J.A.M.S."). The hearing shall be conducted at a location 
determined by the arbitrator in Los Angeles, California and shall be 
administered by and in accordance with the then existing Rules of Practice 
and Procedure of Judicial Arbitration & Mediation Services, Inc., and 
judgment upon any award rendered by the arbitrator may be entered by an State 
or Federal Court having jurisdiction thereof.  The arbitrator shall determine 
which is the prevailing party or parties and shall include in the award that 
party's or parties' reasonable attorneys' fees and costs.  As soon as 
practicable after selection of the arbitrator, the arbitrator or his/her 
designated representative shall determine a reasonable estimate of 
anticipated fees and costs of the arbitrator, and render a statement to each 
party setting forth that party's pro-rata share of said fees and costs. 
Thereafter each party shall, within ten days of receipt of said statement, 
deposit said sum with the arbitrator.  Failure of any party to make such a 
deposit shall result in a forfeiture by the non-depositing party of the right 
to prosecute or defend that claim which is the subject of the arbitration, 
but shall not otherwise serve to abate, stay under this paragraph, nor any 
other provision of this dispute resolution provision, or limit the right of 
any party to obtain provisional or ancillary remedies such as injunctive 
relief from any court having jurisdiction before, during or after the 
pendency of any arbitration.  The institution and maintenance of any action 
for the pursuit of provisional or ancillary remedies shall not constitute a 
waiver of the right of any party, including the plaintiff, to submit the 
controversy or claim to arbitration.

                                      THE AGENT


     12.1      APPOINTMENT.  Sanwa is hereby appointed Agent hereunder and 
under each other Loan Document, and each of the Lenders irrevocably 
authorizes the Agent to act as the agent of such Lender.  The Agent agrees to 
act as such upon the express conditions contained in this Article 12.  The 
Agent shall not have a fiduciary relationship in respect of the Borrower or 
any Lender by reason of this Agreement.

     12.2      POWERS.  The Agent shall have and may exercise such powers 
under the Loan Documents as are specifically delegated to the Agent by the 
terms of each thereof, together with such powers as are reasonably incidental 
thereto.  The Agent shall have no implied duties to the Lenders, or any 
obligation to the Lenders to take any action thereunder except any action 
specifically provided by the Loan Documents to be taken by the Agent.

     12.3      GENERAL IMMUNITY.  Neither the Agent nor any of its directors, 
officers, agents or employees shall be liable to the Borrower or any Lender 
for any action taken or omitted to be taken by it or them hereunder or under 
any other Loan Document or in connection herewith or therewith except for its 
or its own gross negligence or willful misconduct.

     12.4      NO RESPONSIBILITY FOR LOANS, RECITALS, ETC.  Neither the Agent 
nor any of its directors, officers, agents or employees shall be responsible 
for or have any duty to ascertain, inquire into, or verify (i) any statement, 
warranty or representation made in connection with any Loan Document or any 
borrowing hereunder; (ii) the performance or observance of any of the 
covenants or agreements of any obligor under any Loan Document, including, 
without limitation, any agreement by an obligor to furnish information 
directly to each Lender; (iii) the satisfaction of any condition specified in 
Article 4 except receipt of items required to be delivered to the Agent; or 
(iv) the validity, effectiveness or genuineness of any Loan Document or any 
other instrument or writing furnished in connection therewith.  The Agent 
shall have no duty to disclose to the Lenders information that is not 
required to be furnished by the Borrower to the Agent at such time, but is 
voluntarily furnished by the Borrower to the Agent (either in its capacity as 
Agent or in its individual capacity).

     12.5      ACTION ON INSTRUCTIONS OF LENDERS.  The Agent shall in all 
cases be fully protected in acting, or in refraining from acting, hereunder 
and under any other Loan Document in accordance with written instructions 
signed by the Required Lenders, and such instructions and any action taken or 
failure to act pursuant thereto shall be binding on all of the Lenders and on 
all holders of Notes.  The Agent shall be fully justified in failing or 
refusing to take any action hereunder and under any other Loan Document 
unless it shall first be indemnified to its satisfaction by the Lenders pro 
rata against any and all liability, cost and expense that it may incur by 
reason of taking or continuing to take any such action.

     12.6      EMPLOYMENT OF AGENTS AND COUNSEL.  The Agent may execute any 
of its duties as Agent hereunder and under any other Loan Document by or 
through employees, agents, and attorneys-in-fact and shall not be answerable 
to the Lenders, except as to money or securities received by it or its 
authorized agents, for the default or misconduct of any such agents or 
attorneys-in-fact selected by it with reasonable care.  The Agent shall be 
entitled to advice of counsel concerning all matters pertaining to the agency 
hereby created and its duties hereunder and under any other Loan Document.

     12.7      RELIANCE ON DOCUMENTS; COUNSEL.  The Agent shall be entitled 
to rely upon any Note, notice, consent, certificate, affidavit, letter, 
telegram, statement, paper or document believed by it to be genuine and 
correct and to have been signed

                                     -53-

<PAGE>

or sent by the proper person or persons, and, in respect to legal matters, 
upon the opinion of counsel selected by the Agent, which counsel may be 
employees of the Agent.

     12.8      AGENT'S REIMBURSEMENT AND INDEMNIFICATION.  The Lenders agree 
to reimburse and indemnify the Agent ratably in proportion to its respective 
Commitments (i) for any other expenses incurred by the Agent on behalf of the 
Lenders, in connection with the preparation, execution, delivery, 
administration and enforcement of the Loan Documents and (ii) for any 
liabilities, obligations, losses, damages, penalties, actions, judgments, 
suits, costs, expenses or disbursements of any kind and nature whatsoever 
which may be imposed on, incurred by or asserted against the Agent in any way 
relating to or arising out of the Loan Documents or any other document 
delivered in connection therewith or the transactions contemplated thereby, 
or the enforcement of any of the terms thereof or of any such other 
documents, provided that no Lender shall be liable for any of the foregoing 
to the extent they arise from the gross negligence or willful misconduct of 
the Agent.  The obligations of the Lenders under this Section 12.8 shall 
survive payment of the Obligations and termination of this Agreement.

     12.9      RIGHTS AS A LENDER.  In the event the Agent is a Lender, the 
Agent shall have the same rights and powers hereunder and under any other 
Loan Document as any Lender and may exercise the same as though it were not 
the Agent, and the term "Lender" or "Lenders" shall, at any time when the 
Agent is a Lender, unless the context otherwise indicates, include the Agent 
in its individual capacity.  The Agent may accept deposits from, lend money 
to, and generally engage in any kind of trust, debt, equity or other 
transaction, in addition to those contemplated by this Agreement or any other 
Loan Document, with the Borrower or any of its Subsidiaries in which the 
Borrower or such Subsidiary is not restricted hereby from engaging with any 
other Person.

     12.10     LENDER CREDIT DECISION.  Each Lender acknowledges that it has,
independently and without reliance upon the Agent or any other Lender and based
on the financial statements prepared by the Borrower and such other documents
and information as it has deemed appropriate, made its own credit analysis and
decision to enter into this Agreement and the other Loan Documents.  Each Lender
also acknowledges that it will, independently and without reliance upon the
Agent or any other Lender and based on such documents and information as it
shall deem appropriate at the time, continue to make its own credit decisions in
taking or not taking action under this Agreement and the other Loan Documents.

     12.11     SUCCESSOR AGENT.  The Agent may resign at any time by giving
written notice thereof to the Lenders and the Borrower, such resignation to be
effective upon the appointment

                                     -54-

<PAGE>

of a successor Agent or, if no successor Agent has been appointed, forty-five 
days after the retiring Agent gives notice of its intention to resign.  Upon 
any such resignation, the Required Lenders shall have the right to appoint, 
with the consent (which shall not be unreasonably withheld) of the Borrower, 
if no Default has occurred and is continuing, on behalf of the Borrower and 
the Lenders, a successor Agent.  If no successor Agent shall have been so 
appointed by the Required Lenders within thirty days after the resigning 
Agent's giving notice of its intention to resign, then the resigning Agent 
may appoint, on behalf of the Borrower and the Lenders, a successor Agent.  
If the Agent has resigned and no successor Agent has been appointed, the 
Lenders may perform all the duties of the Agent hereunder and the Borrower 
shall make all payments in respect of the Obligations to the applicable 
Lender and for all other purposes shall deal directly with the Lenders.  No 
successor Agent shall be deemed to be appointed hereunder until such 
successor Agent has accepted the appointment.  Any such successor Agent shall 
be a commercial bank having capital and retained earnings of at least 
$50,000,000. Upon the acceptance of any appointment as Agent hereunder by a 
successor Agent, such successor Agent shall thereupon succeed to and become 
vested with all the rights, powers, privileges and duties of the resigning 
Agent.  Upon the effectiveness of the resignation of the Agent, the resigning 
Agent shall be discharged from its duties and obligations hereunder and under 
the Loan Documents.  After the effectiveness of the resignation of an Agent, 
the provisions of this Article 10 shall continue in effect for the benefit of 
such Agent in respect of any actions taken or omitted to be taken by it while 
it was acting as the Agent hereunder and under the other Loan Documents.

                               SETOFF; RATABLE PAYMENTS


     13.1 SETOFF.  Upon the occurrence and during the continuance of any Event
of Default, the Lenders are hereby authorized at any time and from time to time,
to the fullest extent permitted by law, to set off and apply any and all
deposits (general or special, time or demand, provisional or final) at any time
held and other indebtedness at any time owing by any Lender to or for the credit
or the account of the Borrower against any and all obligations of the Borrower
now or hereafter existing under the Loan Documents, irrespective of whether or
not any Lender shall have made any demand under this Agreement and although such
obligations may be unmatured.  The rights of the Lenders under this Section are
in addition to other rights and remedies (including other rights of setoff) that
the Lenders may have.

                                     -55-

<PAGE>

     13.2 RATABLE PAYMENTS.  If any Lender, whether by setoff or otherwise, has
payment made to it upon its Loans (other than payments received pursuant to
Section 3.1 or 3.2) in a greater proportion than that received by any other
Lender, such Lender agrees, promptly upon demand, to purchase a portion of the
Loans held by the other Lenders so that after such purchase each Lender will
hold its ratable proportion of Loans.  If any Lender, whether in connection with
setoff or amounts which might be subject to setoff or otherwise, receives
collateral or other protection for its Obligations or such amounts which may be
subject to setoff, such Lender agrees, promptly upon demand, to take such action
necessary such that all Lenders share in the benefits of such collateral ratably
in proportion to its Loans.  In case any such payment is disturbed by legal
process, or otherwise, appropriate further adjustments shall be made.


                                      ARTICLE 14

                  BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS


     14.1 SUCCESSORS AND ASSIGNS.  The terms and provisions of the Loan
Documents shall be binding upon and inure to the benefit of the Borrower and the
Lenders and its respective successors and assigns, except that (i) the Borrower
shall not have the right to assign its rights or obligations under the Loan
Documents and (ii) any assignment by any Lender must be made in compliance with
Section 14.3.  Notwithstanding clause (ii) of this Section, any Lender may at
any time, without the consent of the Borrower or the Agent, assign all or any
portion of its rights under this Agreement and its Notes to a Federal Reserve
Bank; provided, however, that no such assignment shall release the transferor
Lender from its obligations hereunder.  The Agent and the Borrower may treat the
payee of any Note as the owner thereof for all purposes hereof unless and until
such payee complies with Section 14.3 in the case of an assignment thereof or,
in the case of any other transfer, a written notice of the transfer is filed
with the Agent.  Any assignee or transferee of a Note agrees by acceptance
thereof to be bound by all the terms and provisions of the Loan Documents.  Any
request, authority or consent of any Person, who at the time of making such
request or giving such authority or consent is the holder of any Note, shall be
conclusive and binding on any subsequent holder, transferee or assignee of such
Note or of any Note or Notes issued in exchange therefor.

     14.2 PARTICIPATIONS.

          (i)       PERMITTED PARTICIPANTS; EFFECT.  Any Lender may, in the
     ordinary course of its business and in accordance with applicable law, at
     any time sell to one or more banks or other entities ("Participants")
     participating interests in any Loan owing to such Lender, any Note held

                                     -56-

<PAGE>

     by such Lender, any Commitment of such Lender or any other interest of such
     Lender under the Loan Documents.  In the event of any such sale by a Lender
     of participating interests to a Participant, such Lender's obligations
     under the Loan Documents shall remain unchanged, such Lender shall remain
     solely responsible to the other parties hereto for the performance of such
     obligations, such Lender shall remain the holder of any such Note for all
     purposes under the Loan Documents, all amounts payable by the Borrower
     under this Agreement shall be determined as if such Lender had not sold
     such participating interests, and the Borrower and the Agent shall continue
     to deal solely and directly with such Lender in connection with such
     Lender's rights and obligations under the Loan Documents.

          (ii)  VOTING RIGHTS.  Each Lender shall retain the sole right to
     approve, without the consent of any Participant, any amendment,
     modification or waiver of any provision of the Loan Documents other than
     any amendment, modification or waiver with respect to any Loan or
     Commitment in which such Participant has an interest which forgives
     principal, interest or fees or reduces the interest rate or fees payable
     with respect to any such Loan or Commitment or postpones any date fixed for
     any regularly-scheduled payment of principal of, or interest or fees on,
     any such Loan or Commitment.

          (iii)     BENEFIT OF SETOFF.  The Borrower agrees that each
     Participant shall be deemed to have the right of setoff provided in
     Section 13.1 in respect of its participating interest in amounts owing
     under the Loan Documents to the same extent as if the amount of its
     participating interest were owing directly to it as a Lender under the Loan
     Documents, provided that each Lender shall retain the right of setoff
     provided in Section 13.1 with respect to the amount of participating
     interests sold to each Participant.  The Lenders agree to share with each
     Participant, and each Participant, by exercising the right of setoff
     provided in Section 11.1, agrees to share with each Lender, any amount
     received pursuant to the exercise of its right of setoff, such amounts to
     be shared in accordance with Section 13.2 as if each Participant were a
     Lender.

     14.3 ASSIGNMENTS.

          (i)       PERMITTED ASSIGNMENTS.  Any Lender may, in the ordinary
     course of its business and in accordance with applicable law, at any time
     assign to one or more Eligible Assignees ("Purchasers") all or any part of
     its rights and obligations under the Loan Documents, provided, however,
     such assignments must be in a minimum amount at least equal to $2,000,000
     and must be on a pro rata basis of all Obligations hereunder; provided,
     however, that if such

                                     -57-

<PAGE>

     Purchaser is a Lender or an Affiliate thereof, no minimum amount shall be 
     applicable.  Such assignment shall be substantially in the form of 
     Exhibit C hereto or in such other form as may be agreed to by the parties 
     thereto.  The consent of the Borrower and the Agent shall be required prior
     to an assignment becoming effective with respect to a Purchaser which is 
     not a Lender or an Affiliate thereof; provided, however, that if a Default 
     has occurred and is continuing, the consent of the Borrower shall not be 
     required.  Such consent shall not be unreasonably withheld or delayed.  
     Each such assignment shall comply with all applicable Governmental Rules.

          (ii) EFFECT; EFFECTIVE DATE.  Upon (i) delivery to the Agent of a
     notice of assignment, substantially in the form attached as Exhibit I to
     Exhibit C hereto (a "Notice of Assignment"), together with any consents
     required by Section 14.3(i), and (ii) payment of a $3,000 fee to the Agent
     for processing such assignment, such assignment shall become effective on
     the effective date specified in such Notice of Assignment.  The Notice of
     Assignment shall contain a representation by the Purchaser to the effect
     that it is an Eligible Assignee and that none of the consideration used to
     make the purchase of the Commitment and Loans under the applicable
     assignment agreement are "plan assets" as defined under ERISA and that the
     rights and interests of the Purchaser in and under the Loan Documents will
     not be "plan assets" under ERISA.  On and after the effective date of such
     assignment, such Purchaser shall for all purposes be a Lender party to this
     Agreement and any other Loan Document executed by the Lenders and shall
     have all the rights and obligations of a Lender under the Loan Documents,
     to the same extent as if it were an original party hereto, and no further
     consent or action by the Borrower, the Lenders or the Agent shall be
     required to release the transferor Lender with respect to the percentage of
     the Aggregate Commitment and Loans assigned to such Purchaser.  Upon the
     consummation of any assignment to a Purchaser pursuant to this
     Section 14.3(ii), the transferor Lender, the Agent and the Borrower shall
     make appropriate arrangements so that replacement Notes are issued to such
     transferor Lender and new Notes or, as appropriate, replacement Notes, are
     issued to such Purchaser, in each case in principal amounts reflecting its
     Commitment, as adjusted pursuant to such assignment.

     14.4 DISSEMINATION OF INFORMATION.  The Borrower authorizes each Lender to
disclose to any Participant or Purchaser or any other Person acquiring an
interest in the Loan Documents by operation of law (each a "Transferee") and any
prospective Transferee any and all information in such Lender's possession
concerning the creditworthiness of the Borrower and its Subsidiaries, provided
that each prospective Transferee

                                     -58-

<PAGE>

shall execute and deliver to the Agent a confidentiality agreement (in form 
and substance reasonably satisfactory to the Borrower and the Agent).

     14.5 TAX TREATMENT.  If any interest in any Loan Document is transferred to
any Transferee which is organized under the laws of any jurisdiction other than
the United States or any State thereof, the transferor Lender shall cause such
Transferee, concurrently with the effectiveness of such transfer, to comply with
the provisions of Section 2.21.

and each party has notified the Agent by telex or telephone, that it has taken
such action.

     Ratio set forth in the most recent quarterly Compliance Certificate 
     delivered by the Borrower to the Agent pursuant to Section 7.1(iii), 
     together with the accompanying required quarterly or annual financial 
     statements. For accrued and unpaid interest only (no changes being made 
     for interest payments previously made), changes in interest rates on the 
     Fixed Rate Loans attributable to changes in the Applicable Margin caused 
     by changes in the applicable Funded Debt Ratio Level shall be calculated 
     upon the delivery of a quarterly Compliance Certificate pursuant to 
     Section 7.1(iii), together with the accompanying required quarterly or 
     annual financial statements, setting forth such Funded Debt Ratio and the 
     applicable Funded Debt Ratio Level, and such change shall be effective 
     from the first day of the Interest Period applicable to such Fixed Rate 
     Loans subsequent to the delivery of such quarterly Compliance Certificate.
     If, for any reason, the Borrower shall fail to deliver a quarterly 
     Compliance Certificate, together with the accompanying required quarterly
     or annual financial statements, setting forth the Funded Debt ratio and 
     the applicable Funded Debt Ratio Level when due in accordance with 
     Section 7.1(iii), and such failure shall continue for a period of twenty 
     days, the Funded Debt Ratio Level shall be deemed to be Level 4, 
     retroactive to the date on which the Borrower should have delivered such 
     quarterly Compliance Certificate and shall continue until a Compliance 
     Certificate indicating a different Funded Debt Ratio Level is delivered 
     to the Agent."

     (j) Section 6.4 of the Credit Agreement is amended in its entirety to 
read as follows:

     "6.4  MINIMUM CURRENT RATIO. The Borrower and its Subsidiaries on a 
     Consolidated Basis shall maintain at all times a ratio of Current Assets 
     to Current Liabilities of not less than (i) 1.19:1.00 for the fiscal year

     showing the calculations necessary to determine compliance with this 
     Agreement (including the Funded Debt Ratio as of the end of the applicable
     fiscal quarter for the period of the four fiscal quarters then ended and 
     the applicable Funded Debt Ratio Level) and stating that no Default or 
     Event of Default exists, or if any Default or Event of Default exists, 
     stating the nature and status thereof."

     (m) Schedule 5 to the Credit Agreement is deleted in its entirety.

     (n) Exhibit B to the Credit Agreement is amended in its entirety as set 
forth in Addendum II hereto.

     (o) Exhibit B to the Credit Agreement is amended in its entirety as set 
forth in Addendum II hereto.

     Section 2.  TERMINATION OF SECURITY AGREEMENT. Notwithstanding anything 
to the contrary in the Security Agreement, the Security Agreement is 
terminated as of the date of this Amendment, and the Agent shall file 
appropriate UCC Termination Statements and release any collateral pledged in 
connection therewith.

     Section 3.  REPRESENTATIONS AND WARRANTIES.  The Borrower represents and 
warrants to the Agent and the Lender (and for the benefit of any other Lender 
from time to time party to the Credit Agreement) as follows:

duly authorized and approved by all necessary action;

the Credit Agreement are true and correct on and as of the date hereof as 
though made on and as of the date hereof, except to the extent any such 
representation or warranty shall be true and correct on and as of such 
earlier date; and

     (d) no Event of Default or Default has occurred and is continuing.

     Section 4.  CONDITION PRECEDENTS. The effectiveness of this Amendment as 
of the date first above written is subject to the conditions precedent that

     (a) Except as expressly set forth herein, all provisions of the Credit 
Agreement and the other Loan Documents shall continue in full force and

Agreement, as amended hereby.

     (b) This Amendment may be executed in any number of counterparts and by 
different parties hereto on separate counterparts, each of which counterparts 
so executed and delivered shall be deemed to be an original, and all of which 
counterparts, taken together, shall constitute but one and the same Amendment.

     (c) This Amendment and the rights and obligations of the parties under 
this Amendment shall be governed by, and construed and interpreted in 
accordance with, the law of the State of California.

                        STANDARD FORM OF OFFICE LEASE     
                   THE REAL ESTATE BOARD OF NEW YORK, INC.
                   =======================================

AGREEMENT OF LEASE, made as of this       day of February 1993, between 
     HUDSON TELEGRAPH ASSOCIATES, having an office c/o William Real Estate 
     Co. Inc., 630 Fifth Avenue, New York, New York 10036 party of the first 
     part, hereinafter referred to as OWNER, and AMERICAN COMMUNICATIONS 
     CORP., a Delaware corporation having an office at T-ONE CORP. party of 
     the second part, hereinafter referred to as TENANT

WITNESSETH:      Owner hereby leases to Tenant and Tenant hereby hires from 
Owner room 316 (the "demised premises") substantially as shown on the plan 
annexed as Exhibit A in the building known as 60 Hudson Street in the Borough 
of Manhattan, City of New York, for the term (the "Term") to commence on the 
date hereof (the "Commencement Date") and to end on July 31, 2003 (the 
"Expiration Date") at a fixed annual rental rate (the "Fixed Rent") of (a) 
$39,996 per annum from the Commencement Date through July 31, 1998 and (B) 
$44,440 per annum from August 1, 1998 through the Expiration Date.

which Tenant agrees to pay in lawful money of the United States which shall 
be legal tender in payment of all debts and dues, public and private, at the 
time of payment, in equal monthly installments in advance on the first day of 
each month during said term, at the office of Owner or such other place as 
Owner may designate, without any set off or deduction whatsoever, except that 
Tenant shall pay the first       monthly installment(s) on the execution 
hereof (unless this lease be a renewal).

     In the event that, at the commencement of the term of this lease, or 
thereafter, Tenant shall be in default in the payment of rent to Owner 
pursuant to the terms of another lease with Owner or with Owner's predecessor 
in interest, Owner may at Owner's option and without notice to Tenant add the 
amount of such arrears to any monthly installment of rent payable hereunder 
and the same shall be payable to Owner as additional rent.

     The parties hereto, for themselves, their heirs, distributees, 
executors, administrators, legal representatives, successors and assigns, 
hereby convenant as follows:

RENT   1.  Tenant shall pay the rent as above and as hereinafter provided. 

OCCUPANCY   2.  Tenant shall use and occupy demised premises for general
offices and a telecommunications switching facility       and for no other
purposes.

TENANT ALTERATIONS:
     3.  Tenant shall make no changes in or to the demised premises of any 
nature without Owner's prior written consent. Subject to the prior written 
consent of Owner, and to the provisions of this article, Tenant at Tenant's 
expense, may make alterations, installations, additions or improvements which 
are nonstructural and which do not affect utility services or plumbing and 
electrical lines, in or to the interior of the demised premises by using 
contractors or mechanics first approved by Owner. Tenant shall, before making 
any alterations, additions, installations or improvements, at its expense, 
obtain all permits, approvals and certificates required by any governmental 
or quasi-governmental bodies and (upon completion) certificates of final 
approval thereof and shall deliver promptly duplicates of all such permits, 
approvals and certificates to Owner and Tenant agrees to carry and will cause 
Tenant's contractors and sub-contractors to carry such workman's 
compensation, general liability, personal and property damages insurance as 
Owner may require. If any mechanic's lien is filed against the demised 
premises, or the building of which the same forms a part, for work claimed to 
have been done for, or materials furnished to, Tenant, whether or not done 
pursuant to this article, the same shall be discharged by Tenant within 
thirty days thereafter, at Tenant's expense, by filling the bond required by 
law. All fixtures and all paneling, partitions, railings and like 
installations, installed in the premises at any time, either by Tenant or by 
Owner in Tenant's behalf, shall, upon installation, become the property of 
Owner and shall remain upon and be surrendered with the demised premises 
unless Owner, by notice to Tenant no later than twenty days prior to the date 
fixed as the termination of this lease, elects to relinquish Owner's right 
therein and to have them removed by Tenant, in which event the same shall be 
removed from the premises by Tenant prior to the expiration of the lease, at 
Tenant's expense. Nothing in this Article shall be construed to give Owner 
title to or to prevent Tenant's removal of trade fixtures, moveable office 
furniture and equipment, but upon removal of any such from the premises or 
upon removal of other installations as may be required by Owner, Tenant shall 
immediately and at its expense, repair and restore the premises to the 
condition existing prior to installation and repair any damage to the demised 
premises or the building due to such removal. All property permitted or 
required to be removed, by Tenant at the end of the term remaining in the 
premises after Tenant's removal shall be deemed abandoned and may, at the 
election of Owner, either be retained as Owner's property or may be removed 
from the premises by Owner, at Tenant's expense.

MAINTENANCE AND REPAIRS

     4.  Tenant shall, throughout the term of this lease, take good care of 
the demised premises and the fixtures and appurtenances therein. Tenant shall 
be responsible for all damage or injury to the demised premises or any other 
part of the building and the systems and equipment thereof, whether requiring 
structural or nonstructural repairs caused by or resulting from carelessness, 
omission, neglect or improper conduct of Tenant, Tenant's subtenants, agents, 
employees, invitees or licensees, or which arise out of any work, labor 
service or equipment done for or supplied to Tenant or any subtenant or 
arising out of the installation, use or operation of the property or 
equipment of Tenant or any subtenant. Tenant shall also repair all damage to 
the building and the demised premises caused by the moving of Tenant's 
fixtures, furniture and equipment. Tenant shall promptly make at Tenant's 
expense, all repairs as and to the demised premises for which Tenant is 
responsible, using only the contractor for the trade or trades in question, 
selected from a list of at least two contractors per trade submited by Owner. 
Any other repairs in or to the building or the facilities and systems thereof 
for which Tenant is responsible shall be performed by Owner at the Tenant's 
expense. Owner shall maintain in good order and repair the exterior and the 
structural portions of the building, including the structural portions of its 
demised premises, and the public portions of the building interior and the 
building plumbing, electrical, heating and ventilating systems (to the extent 
such systems presently exist) serving the demised premises. Tenant agrees to 
give prompt notice of any defective condition in the premises for which Owner 
may be responsible hereunder. There shall be no allowance to Tenant for 
diminution of rental value and no liability on the part of Owner by reason of 
inconvenience, annoyance or injury to business arising from Owner or others 
making repairs, alterations, additions or improvements in or to any portion 
of the building or the demised premises or in and to the fixtures, 
appurtenances or equipment thereof. It is specifically agreed that Tenant 
shall not be entitled to any setoff or reduction of rent by reason of any 
failure of Owner to comply with the covenants of this or any other article of 
this Lease. Tenant agrees that Tenant's sole remedy at law in such instance 
will be by way of an action for damages for breach of contract. The 
provisions of this Article 4 shall not apply in the case of fire or other 
casualty which are dealt with in Article 9 hereof.

WINDOW CLEANING:

     5.  Tenant will not clean or require, permit, suffer or allow any window 
in the demised premises to be cleaned from the outside in violation of 
Section 202 of the Labor Law or any other applicable law or of the Rules of 
the Board of Standards and Appeals, or of any other Board or body having or 
asserting jurisdiction.

REQUIREMENTS OF LAW, FIRE INSURANCE, FLOOR LOADS:

     6.  Prior to the commencement of the lease term, if Tenant is then in 
possession, and at all times thereafter, Tenant, at Tenant's sole cost and 
expense, shall promptly comply with all present and future laws, orders and 
regulations of all state, federal, municipal and local governments, 
departments, commissions and boards and any direction of any public officer 
pursuant to law, and all orders, rules and regulations of the New York Board 
of Fire Underwriters, Insurance Services Officer, or any similar body which 
shall impose any violation, order or duty upon Owner or Tenant with respect 
to the demised premises, whether or not arising out of Tenant's use or manner 
of use thereof, (including Tenant's permitted use) or, with respect to the 
building if arising out of Tenant's

<PAGE>


use or manner of use of the premises or the building (including the use 
permitted under the lease). Nothing herein shall require Tenant to make 
structural repairs or alterations unless Tenant has, by its manner of use of 
the demised premises or method or operation therein, violated any such laws, 
ordinances, orders, rules, regulations or requirements with respect thereto. 
Tenant may, after securing Owner to Owner's satisfaction against all damages, 
interest, penalties and expenses, including, but not limited to, reasonable 
attorney's fees, by cash deposit or by surety bond in an amount and in a 
company satisfactory to Owner, contest and appeal any such laws, ordinances, 
orders, rules, regulations or requirements provided same is done with all 
reasonable promptness and provided such appeal shall not subject Owner to 
prosecution for a criminal offense or constitute a default under any lease or 
mortgage under which Owner may be obligated, or cause the demised premises or 
any part thereof to be condemned or vacated. Tenant shall not do or permit 
any act or thing to be done in or to the demised premises which is contrary 
to law, or which will invalidate or be in conflict with public liability, 
fire or other policies of insurance at any time carried by or for the benefit 
of Owner with respect to the demised premises or the building of which the 
demised premises form part, or which shall or might subject Owner to any 
liability or responsibility to any person or for property damage. Tenant 
shall not keep anything in the demised premises except as now or hereafter 
permitted by the Fire Department, Board of Fire Underwriters, Fire Insurance 
Rating Organization or other authority having jurisdiction, and then only in 
such manner and such quantity so as not to increase the rate for fire 
insurance applicable to the building, nor use the premises in a manner which 
will increase the insurance rate for the building or any property located 
therein over that in effect prior to the commencement of Tenant's occupancy. 
Tenant shall pay all costs, expenses, fines, penalties, or damages, which may 
be imposed upon Owner by reason of Tenant's failure to comply with the 
provisions of this article and if by reason of such failure the fire 
insurance rate shall, at the beginning of this lease or at any time 
thereafter, be higher than it otherwise would be, then Tenant shall reimburse 
Owner, at additional rent hereunder, for that portion of all fire insurance 
premiums thereafter paid by Owner which shall have been charged because of 
such failure by Tenant. In any action or proceeding wherein Owner and Tenant 
are parties, a schedule or "make-up" of rate for the building or demised 
premises issued by the New York Fire Insurance Exchange, or other body making 
fire insurance rates applicable to said premises shall be conclusive evidence 
of the facts therein stated and of the several items and charges in the fire 
insurance rates then applicable to said premises. Tenant shall not place a 
load upon any floor of the demised premises exceeding the floor load per 
square foot area which it was designed to carry and which is allowed by law. 
Owner reserves the right to prescribe the weight and position of all safes, 
business machines and mechanical equipment. Such installations shall be 
placed and maintained by Tenant, at Tenant's expense, in settings sufficient, 
in Owner's judgment, to absorb and prevent vibration, noise and annoyance.


SUBORDINATION:

     7.  This lease is subject and subordinate to all ground or underlying 
leases and to all mortgages which may now or hereafter affect such leases or 
the real property of which demised premises are a part and to all renewals, 
modifications, consolidations, replacements and extensions of any such 
underlying leases and mortgages. This clause shall be self-operative and no 
further instrument of subordination shall be required by any ground or 
underlying lessor or by any mortgagee, affecting any lease or the real 
property of which the demised premises are a part. In confirmation of such 
subordination, Tenant shall execute promptly any certificate that Owner may 
request.


PROPERTY -- LOSS, DAMAGE, REIMBURSEMENT, INDEMNITY:

     8.  Owner or its agents shall not be liable for any damage to property 
of Tenant or of others entrusted to employees of the building, nor for loss 
of or damage to any property of Tenant by theft or otherwise, nor for any 
injury or damage to persons or property resulting from any cause of 
whatsoever nature, unless caused by or due to the negligence of Owner, its 
agents, servants or employees. Owner or its agents will not be liable for any 
such damage caused by other tenants or persons in, upon or about said 
building or caused by operations in construction of any private, public or 
quasi public work.

     If at any time any windows of the demised premises are temporarily 
closed, darkened or bricked up (or permanently closed, darkened or bricked 
up, if required by law) for any reason whatsoever including, but not limited 
to Owner's own acts, Owner shall not be liable for any damage Tenant may 
sustain thereby and Tenant shall not be entitled to any compensation therefor 
nor abatement or diminution of rent nor shall the same release Tenant from 
its obligations hereunder nor constitute an eviction. Tenant shall indemnify 
and save harmless Owner against and from all liabilities, obligations, 
damages, penalties, claims, costs and expenses for which Owner shall not be 
reimbursed by Insurance, including reasonable attorneys fees, paid, suffered 
or incurred as a result of any breach by Tenant, Tenant's agents, 
contractors, employees, invitees, or licensees, of any covenant or condition 
of this lease, or the carelessness, negligence or improper conduct of the 
Tenant, Tenant's agents, contractors, employees, invitees or licensees. 
Tenant's liability under this lease extends to the acts and omissions of any 
sub-tenant, and any agent, contractor, employee, invitee or licensee of any 
sub-tenant. In case any action or proceeding is brought against Owner by 
reason of any such claim, Tenant, upon written notice from Owner, will, at 
Tenant's expense, resist or defend such action or proceeding by counsel 
approved by Owner in writing, such approval not to be unreasonably withheld.


DESTRUCTION, FIRE AND OTHER CASUALTY:

     9.  (a) If the demised premises or any part thereof shall be damaged by 
fire or other casualty, Tenant shall give immediate notice thereof to Owner 
and this lease shall continue in full force and effect except as hereinafter 
set forth. (b) If the demised premises are partially damaged or rendered 
partially unusable by fire or other casualty, the damages thereto shall be 
repaired by and at the expense of Owner and the rent, until such repair shall 
be substantially completed, shall be apportioned from the day following the 
casualty according to the part of the premises which is usable. (c) If the 
demised premises are totally damaged or rendered wholly unusable by fire or 
other casualty, then the rent shall be proportionately paid up to the time of 
the casualty and thenceforth shall cease until the date when the premises 
shall have been repaired and restored by Owner, subject to Owner's right to 
elect not to restore the same as hereinafter provided. (d) If the demised 
premises are rendered wholly unusable or (whether or not the demised premises 
are damaged in whole or in part) if the building shall be so damaged that 
Owner shall decide to demolish it or to rebuild it, then, in may of such 
events, Owner may elect to terminate this lease by written notice to Tenant, 
given within 90 days after such fire or casualty, specifying a date for the 
expiration of the lease, which date shall not be more than 60 days after the 
giving of such notice, and upon the date specified in such notice the term of 
this lease shall expire as fully and completely as if such date were the date 
set forth above for the termination of this lease and Tenant shall forthwith 
quit, surrender and vacate the premises without prejudice however, to 
Landlord's rights and remedies against Tenant under the lease provisions in 
effect prior to such termination, and any rent owing shall be paid up to such 
date and any payments of rent made by Tenant which were on account of any 
period subsequent to such date shall be returned to Tenant. Unless Owner 
shall serve a termination notice as provided for herein, Owner shall make the 
repairs and restorations under the conditions of (b) and (c) hereof, with all 
reasonable expedition, subject to delays due to adjustment of insurance 
claims, labor troubles and causes beyond Owner's control. After any such 
casualty, Tenant shall cooperate with Owner's restoration by removing from 
the premises as promptly as reasonable possible, all of Tenant's salvageable 
inventory and movable equipment, furniture, and other property. Tenant's 
liability for rent shall resume five (5) days after written notice from Owner 
that the premises are substantially ready for Tenant's occupancy. (c) Nothing 
contained hereinabove shall relieve Tenant from liability that may exist as a 
result of damage from fire or other casualty. Notwithstanding the foregoing, 
each party shall look first to any insurance in its favor before making any 
claim against the other party for recovery for loss or damage resulting from 
fire or other casualty, and to the extent that such insurance is in force and 
collectible and to the extent permitted by law, Owner and Tenant each hereby 
releases and waives all right of recovery against the other or any one 
claiming through or under each of them by way of subrogation or otherwise. 
The foregoing release and waiver shall be in force only if both releasors' 
insurance policies contain a clause providing that such a release or waiver 
shall not invalidate the insurance. If, and to the extent, that such waiver 
can be obtained only by the payment of additional premiums, then the party 
benefitting from the waiver shall pay such premium within ten days after 
written demand or shall be deemed to have agreed that the party obtaining 
insurance coverage shall be free of any further obligation under the 
provisions hereof with respect to waiver of subrogation. Tenant acknowledges 
that Owner will not carry insurance on Tenant's furniture and/or furnishings 
or any fixtures or equipment, improvements, or appurtenances removable by 
Tenant and agrees that Owner will not be obligated to repair any damage 
thereto or replace the same. (f) Tenant hereby waives the provisions of 
Section 227 of the Real Property Law and agrees that the provisions of this 
article shall govern and control in lieu thereof.


EMINENT DOMAIN:

     10.  If the whole or any part of the demised premises shall be acquired 
or condemned by Eminent Domain for any public or quasi public use or purpose, 
than and in that event, the term of this lease shall cease and terminate from 
the date of title vesting in such proceeding and Tenant shall have no claim 
for the value of any unexpired term of said lease and assigns to Owner, 
Tenant's entire interest in any such award.


ASSIGNMENT, MORTGAGE, ETC.:

     11.  Tenant, for itself, its heirs, distributees, executors, 
administrators, legal representatives, successors and assigns, expressly 
covenants that it shall not assign, mortgage or encumber this agreement, nor 
underlet, or suffer or permit the demised premises or any part thereof to be 
used by others, without the prior written consent of Owner in each instance. 
Transfer of the majority of the stock of a corporate Tenant shall be deemed 
an assignment. If this lease be assigned, or if the demised premises or any 
part thereof be underlet or occupied by anybody other than Tenant, Owner may, 
after default by Tenant, collect rent from the assignee, under-tenant or 
occupant, and apply the net amount collected to the rent herein reserved, but 
no such assignment, underletting, occupancy or collection shall be deemed a 
waiver of this covenant, or the acceptance of the assignee, under-tenant or 
occupant as tenant, or a release of Tenant from the further performance by 
Tenant of covenants on the part of Tenant herein contained. The consent by 
Owner to an assignment of underletting shall not in any wise be construed to 
relieve Tenant from obtaining the express consent in writing of Owner to any 
further assignment or underletting.


ELECTRIC CURRENT:-icon of hand-

     12.  Rates and conditions in respect to submetering or rent inclusion, 
as the case may be, to be added in RIDER attached hereto. Tenant covenants 
and agrees that at all times its use of electric current shall not exceed the 
capacity of existing feeders to the building or the risers or wiring 
installation and Tenant may not use any electrical equipment which, in 
Owner's opinion, reasonably exercised, will overload such installations or 
interfere with the use thereof by other tenants of the building. The change 
at any time of the character of electric service shall in no wise make Owner 
liable or responsible to Tenant, for any loss, damages or expenses which 
Tenant may sustain.


ACCESS TO PREMISES:

     13.  Owner or Owner's agents shall have the right (but shall not be 
obligated) to enter the demised premises in any emergency at any time, and, 
at other reasonable times, to examine the same and to make such repairs, 
replacements and improvements as Owner may deem necessary and reasonably 
desirable to the demised premises or to any other portion of the building or 
which Owner may elect to perform. Tenant shall permit Owner to use and 
maintain and replace pipes and conduits in and through the demised premises 
and to erect new pipes and conduits therein provided they are concealed 
within the walls, floor, or ceiling. Owner may, during the progress of any 
work in the demised premises, take all necessary materials and equipment into 
said premises without the same constituting an eviction nor shall the Tenant 
be entitled to any abatement of rent while such work is in progress nor to 
any damages by reason of loss or interruption of business or otherwise. 
Throughout the term hereof Owner shall have the right to enter the demised 
premises at reasonable hours for the purpose of showing the

- -------------------
- -icon of hand-  Rider to be added if necessary.

<PAGE>

same to prospective purchasers or mortgagers of the building, and during the 
last six months of the term for the purpose of showing the same to 
prospective tenants. If Tenant is not present to open and permit an entry 
into the premises, Owner or Owner's agents may enter the same whenever such 
entry may be necessary or permissible by master key or forcibly and provided 
reasonable care is exercised to safeguard Tenant's property, such entry shall 
not render Owner or its agents liable therefor, nor in any event shall the 
obligations of Tenant hereunder be affected. If during the last month of the 
term Tenant shall have removed all or substantially all of Tenant's property 
therefrom, Owner may immediately enter, alter, renovate or redecorate the 
demised premises without limitation or abatement of rent, or incurring 
liability to Tenant for any compensation and such acts shall have no effect 
on this lease or Tenant's obligations hereunder.

VAULT, VAULT SPACE, AREA:

     14.  No Vault, vault space or area, whether or not enclosed or covered, 
not within the property line of the building is leased hereunder, anything 
contained in or indicated on any sketch, blue print or plan, or anything 
contained elsewhere in this lease to the contrary notwithstanding. Owner 
makes no representation as to the location of the property line of the 
building. All vaults and vault space and all such areas not within the 
property line of the building, which Tenant may be permitted to use and/or 
occupy, is to be used and/or occupied under a revocable license, and if any 
such license be revoked, or if the amount of such space or area be diminished 
or required by any federal, state or municipal authority or public utility, 
Owner shall not be subject to any liability nor shall Tenant be entitled to 
any compensation or diminution or abatement of rent, nor shall such 
revocation, diminution or requisition be deemed constructive or actual 
eviction. Any tax, fee or charge of municipal authorities for such vault or 
area shall be paid by Tenant.

OCCUPANCY:

     15.  Tenant will not at any time use or occupy the demised premises in 
violation of the certificate of occupancy issued for the building of which 
the demised premises are a part. Tenant has inspected the premises and 
accepts them as is, subject to the riders assessed hereto with respect to 
Owner's work, if any. In any event, Owner makes no representation as to the 
condition of the premises and Tenant agrees to accept the same subject to 
violations, whether or not of record.

BANKRUPTCY:

     16.  (a) Anything elsewhere in this lease to the contrary 
notwithstanding, this lease may be cancelled by Owner by the sending of a 
written notice to Tenant within a reasonable time after the happening of any 
one or more of the following event: (1) the commencement of a case in 
bankruptcy or under the laws of any state naming Tenant as the debtor; or (2) 
the making by Tenant of an assignment or any other arrangement for the 
benefit of creditors under any state statute. Neither Tenant nor any person 
claiming through or under Tenant, or by reason of any statute or order of 
court, shall thereafter be entitled to possession of the premises demised but 
shall forthwith quit and surrender the premises. If this lease shall be 
assigned in accordance with its terms, the provisions of this Article 16 
shall be applicable only to the party then owning Tenant's interest in this 
lease.

          (b) It is stipulated and agreed that in the event of the 
termination of this lease pursuant to (a) hereof, Owner shall forthwith, 
notwithstanding any other provisions of this lease to the contrary, be 
entitled to recover from Tenant as and for liquidated damages an amount equal 
to the difference between the rent reserved hereunder (or the unexpired 
portion of the term demised and the fair and reasonable rental value of the 
demised premises for the same period. In the computation of such damages the 
difference between any installment of rent becoming due hereunder after the 
date of termination and the fair and reasonable rental value of the demised 
premises for the period for which such installment was payable shall be 
discounted to the date of termination at the rate of four percent (4%) per 
annum. If such premises or any part thereof be relet by the Owner for the 
unexpired term of said lease, or any part thereof, before presentation of 
proof of such liquidated damages to any court, commission or tribunal, the 
amount of rent reserved upon such reletting shall be deemed to be the fair 
and reasonable rental value for the part or the whole of the premises so 
re-let during the term of the re-letting. Nothing herein contained shall 
limit or prejudice the right of the Owner to prove for and obtain as 
liquidated damages by reason of such termination, an amount equal to the 
maximum allowed by any statute or rule of law in effect at the time when, and 
governing the proceedings in which, such damages are to be proved, whether or 
not such amount be greater, equal to, or less than the amount of the 
difference referred to above.

DEFAULT

     17. (1) If Tenant defaults in fulfilling any of the covenants of this 
lease or if the demised premises becomes vacant or deserted; or if any 
execution or attachment shall be issued against Tenant or any of Tenant's 
property whereupon the demised premises shall be taken or occupied by someone 
other than Tenant; or if this lease be rejected under Section 235 of Title 11 
of the U.S. Code (bankruptcy code); or if Tenant shall fail to move into or 
take possession of the premises within fifteen (15) days after the 
commencement of the term of this lease, then, in any one or more of such 
events, upon Owner serving a written five (5) days notice upon Tenant 
specifying the nature of said default and upon the expiration of said five 
(5) days, if Tenant shall have failed to comply with or remedy such default, 
or if the said default or omission complained of shall be of a nature that 
the same cannot be completely cured or remedied within said five (5) day 
period, and if Tenant shall not have diligently commenced during such default 
within such five (5) day period, and shall not thereafter with reasonable 
diligence and in good faith, proceed to remedy or cure such default, then 
Owner may serve a written three (3) days notice of cancellation of this lease 
upon Tenant, and upon the expiration of said three (3) days this lease and 
the term thereunder shall end and expire as fully and completely as if the 
expiration of such three (3) day period were the day herein definitely fixed 
for the end and expiration of this lease and the term thereof and Tenant 
shall then quit and surrender the demised premises to Owner but Tenant shall 
remain liable as hereinafter provided.

          (2) If the notice provided for in (1) hereof shall have been given, 
and the term shall expire as aforesaid; or if Tenant shall make default in 
the payment of the rent reserved herein or any item of additional rent herein 
mentioned or any part of either or in making any other payment herein 
required; then and in any of such events Owner may without notice, re-enter 
the demised premises either by force or otherwise, and dispossess Tenant by 
summary proceedings or otherwise, and the legal representative of Tenant or 
other occupant of demised premises and remove their effects and hold the 
premises as if this lease had not been made, and Tenant hereby waives the 
service of notice of intention to re-enter or to institute legal proceedings 
to that end. If Tenant shall make default hereunder prior to the date fixed 
as the commencement of any renewal or extension of this lease, Owner may 
cancel and terminate such renewal or extension agreement by written notice.

REMEDIES OF OWNER AND WAIVER OF REDEMPTION:

     18. In case of any such default, re-entry, expiration and/or dispossess 
by summary proceedings or otherwise, (a) the rent shall become due thereupon 
and be paid up to the time of such re-entry, dispossess and/or expiration, 
(b) Owner may re-let the premises or any part or parts thereof, either in the 
name of Owner or otherwise, for a term or terms, which may at Owner's option 
be less than or exceed the period which would otherwise have constituted the 
balance of the term of this lease and may grant concessions or free rent or 
charge a higher rental than that in this lease, and/or (c) Tenant or the 
legal representatives of Tenant shall also pay Owner as liquidated damages 
for the failure of Tenant to observe and perform said Tenant's covenants 
herein contained, any deficiency between the rent hereby reserved and/or 
covenanted to be paid and the net amount, if any, of the rents collected on 
account of the lease or leases of the demised premises for each month of the 
period which would otherwise have constituted the balance of the term of this 
lease. The failure of Owner to re-let the premises or any part or parts 
thereof shall not release or affect Tenant's liability for damages. In 
computing such liquidated damages there shall be added to the said deficiency 
such expenses as Owner may incur in connection with re-letting, such as legal 
expenses, attorneys' fees, brokerage, advertising and for keeping the demised 
premises in good order or for preparing the same for re-letting. Any such 
liquidated damages shall be paid in monthly installments by Tenant on the 
rent day specified in this lease and any suit brought to collect the amount 
of the deficiency for any month shall not prejudice in any way the rights of 
Owner to collect the deficiency for any month shall not prejudice in any way 
the rights of Owner to collect the deficiency of any subsequent month by a 
similar proceeding. Owner, in putting the demised premises in good order or 
preparing the same for re-rental may, at Owner's option, make such 
alterations, repairs, replacements, and/or decorations in the demised 
premises as Owner, in Owner's sole judgment, considers advisable and 
necessary for the purpose of re-letting the demised premises, and the making 
of such alterations, repairs, replacements, and/or decorations shall not 
operate or be construed to release Tenant from liability hereunder as 
aforesaid. Owner shall in no event be liable in any way whatsoever for 
failure to re-let the demised premises, or in the event that the demised 
premises are re-let, for failure to collect the rent thereof under such 
re-letting, and in no event shall Tenant be entitled to receive any excess, 
if any, of such net rents collected over the sums payable by Tenant to Owner 
hereunder. In the event of a breach or threatened breach by Tenant of any of 
the covenants or provisions hereof, Owner shall have the right of injunction 
and the right to invoke any remedy allowed at law or in equity as if 
re-entry, summary proceedings and other remedies were not herein provided 
for. Mention in this lease of any particular remedy, shall not preclude Owner 
from any other remedy, in law or in equity. Tenant hereby expressly waives 
any and all rights of redemption granted by or under any present or future 
laws in the event of Tenant being evicted or dispossessed for any cause, or 
in the event of Owner obtaining possession of demised premises, by reason of 
the violation by Tenant of any of the covenants and conditions of this lease, 
or otherwise.

FEES AND EXPENSES

     19.  If Tenant shall default in the observance or performance of any 
term or covenant on Tenant's part to be observed or performed under or by 
virtue of any of the terms or provisions in any article of this lease, then, 
unless otherwise provided elsewhere in this lease, Owner may immediately or 
at any time thereafter and without notice perform the obligation of Tenant 
thereunder. If Owner, in connection with the foregoing or in connection with 
any default by Tenant in the covenant to pay rent hereunder, makes any 
expenditures or incurs any obligations for the payment of money, including 
but not limited to attorney's fees, in instituting, prosecuting or defending 
any action or proceeding, then Tenant will reimburse Owner for such sums so 
paid or obligations incurred with interest and costs. The foregoing expenses 
incurred by reason of Tenant's default shall be deemed to be additional rent 
hereunder and shall be paid by Tenant to Owner within five (5) days of 
rendition of any bill or statement to Tenant therefor. If Tenant's lease term 
shall have expired at the time of making of such expenditures or incurring of 
such obligations, such sums shall be recoverable by Owner as damages.

BUILDING ALTERATIONS AND MANAGEMENT:

     20.  Owner shall have the right at any time without the same 
constituting an eviction and without incurring liability to Tenant therefor 
to change the arrangement and/or location of public entrances, passageways, 
doors, doorways, corridors, elevators, stairs, toilets or other public parts 
of the building and to change the name, number or designation by which the 
building may be known. There shall be no allowance to Tenant for diminution 
of rental value and no liability on the part of Owner by reason of 
inconvenience, annoyance or injury to business arising from Owner or other 
Tenants making any repairs in the building or any such alterations, additions 
and improvements. Furthermore, Tenant shall not have any claim against Owner 
by reason of Owner's imposition of such controls of the manner of access to 
the building by Tenant's social or business visitors as the Owner may deem 
necessary for the security of the building and its occupants.

NO REPRESENTATIONS BY OWNER:

     21.  Neither Owner nor Owner's agents have made any representations or 
promises with respect to the physical condition of the building, the land 
upon which

operation or any other matter or thing affecting or related to the premises 
except as herein expressly set forth and no rights, easements or licenses are 
acquired by Tenant by implication or otherwise except as expressly set forth 
in the provisions of this lease. Tenant has inspected the building and the 
demised premises and is thoroughly acquainted with their condition and agrees 
to take the same "as is" and acknowledges that the taking of possession of 
the demised premises by Tenant shall be conclusive evidence that the said 
premises and the building of which the same form a part were in good and 
satisfactory condition at the time such possession was so taken, except as to 
latent defects. All understandings and agreements heretofore made between the 
parties hereto are merged in this contract, which alone fully and completely 
expresses the agreements between Owner and Tenant and any executory agreement 
hereafter made shall be ineffective to change, modify, discharge or effect an 
abandonment of it in whole or in part, unless such executory agreement is in 
writing and signed by the party against whom enforcement of the change, 
modification, discharge or abandonment is sought.

in good order and condition, ordinary wear and damages which Tenant is not 
required to repair as provided elsewhere in this lease excepted, and Tenant 
shall remove all its property. Tenant's obligation to observe or perform the 
covenant shall survive the expiration or other termination of this lease. If 
the last day of the term of this Lease or any renewal thereof, falls on 
Sunday, this lease shall expire at noon on the preceding Saturday unless it 
be a legal holiday in which case it shall expire at noon on the preceding 
business day.

QUIET ENJOYMENT:

     23.  Owner covenants and agrees with Tenant that upon Tenant paying the 
rent and additional rent and observing and performing all the items, 
covenants and conditions, on Tenant's part to be observed and performed. 
Tenant may peaceably and quietly enjoy the premises hereby demised, subject, 
nevertheless, to the terms and conditions of this lease including, but not 
limited to, Article 11 hereof and to the ground leases, underlying leases and 
mortgages hereinbefore mentioned.

FAILURE TO GIVE POSSESSION:

     24.  If Owner is unable to give possession of the demised premises on 
the date of the commencement of the term hereof, because of the holding-over 
or retention of possession of any tenant, undertenant or occupants or if the 
demised premises are located in a building being constructed, because such 
building has not been sufficiently completed to make the premises ready for 
occupancy or because of the fact that a certificate of occupancy has not been 
procured or for any other reason. Owner shall not be subject to any liability 
for failure to give possession on said date and the validity of the lease 
shall not be impaired under such circumstances, nor shall the same be 
construed in any wise to extend the term of this lease, but the rent payable 
hereunder shall be abated (provided Tenant is not responsible for Owner's 
inability to obtain possession) until after Owner shall have a given Tenant 
written notice that the premises are substantially ready for Tenant's 
occupancy. If permission is given to Tenant to enter into the possession of 
the demised premises or to occupy premises other than the demised premises 
prior to the date specified as the commencement of the term of this lease. 
Tenant covenants and agrees that such occupancy shall be deemed to be under 
all the terms, covenants, conditions and provisions of this lease, except as 
to the covenant to pay rent. The provisions of this article are intended to 
constitute "an express provision to the contrary" within the meaning of 
Section 223-a of the New York Real Property Law.

NO WAIVER:

     25.  The failure of Owner to seek redress for violation of, or to insist 
upon the strict performance of any covenant or condition of this lease or of 
any of the Rules or Regulations, set forth or hereafter adopted by Owner, 
shall not prevent a subsequent act which would have originally constituted a 
violation from having all the force and effect of an original violation. The 
receipt by Owner of rent with knowledge of the breach of any covenant of this 
lease shall not be deemed a waiver of such breach and no provision of this 
lease shall be deemed to have been waived by Owner unless such waiver be in 
writing signed by Owner. No payment by Tenant or receipt by Owner of a lesser 
amount than the monthly rent herein stipulated shall be deemed to be other 
than on account of the earliest stipulated rent, nor shall any endorsement or 
statement of any check or any letter accompanying any check or payment as 
rent be deemed an accord and satisfaction, and Owner may accept such check or 
payment without prejudice to Owner's right to recover the balance of such 
rent or pursue any other remedy in this lease provided. No act or thing done 
by Owner or Owner's agents during the term hereby demised shall be deemed an 
acceptance of a surrender of said premises, and no agreement to accept such 
surrender shall be valid unless in writing signed by Owner. No employee of 
Owner or Owner's agent shall have power to accept the keys of said premises 
prior to the termination of the lease and the delivery of keys to any such 
agent or employee shall not operate as a termination of the lease or a 
surrender of the premises.

WAIVER OF TRIAL BY JURY:

     26.  It is mutually agreed by and between Owner and Tenant that the 
respective parties hereto shall and they hereby do waive trial by jury in any 
action, proceeding or counter-claim brought by either of the parties hereto 
against the other (except for personal injury or property damage) on any 
matters whatsoever arising out of or in any way connected with this lease, 
the relationship of Owner and Tenant, Tenant's use of or occupancy of said 
premises and any emergency statutory or any other statutory remedy. It is 
further mutually agreed that in the event Owner commences any summary 
proceeding for possession of the premises, Tenant will not interpose any 
counterclaim of whatever nature or description in any such proceeding 
including a counterclaim under Article 4.

INABILITY TO PERFORM:

     27.  This Lease and the obligation of Tenant to pay rent hereunder and 
perform all of the other covenants and agreements hereunder on part of Tenant 
to be performed shall in no wise be affected, impaired or excused because 
Owner is unable to fulfill any of its obligations under this lease or to 
supply or is delayed in supplying any service expressly or impliedly to be 
supplied or is unable to make, or is delayed in making any repair, additions, 
alterations or decorations or is unable to supply or is delayed in supplying 
any equipment or fixtures if Owner is prevented or delayed from so doing by 
reason of strike or labor troubles or any cause whatsoever including, but not 
limited to, government preemption in connection with a National Emergency or

thereof of any government agency or by reason of the conditions of supply and 
demand which have been or are affected by war or other emergency.

38.  RENTAL PAYMENTS

     (A)  All payments other than Fixed Rent to be made by Tenant pursuant to 
this lease shall be deemed additional rent and, in the event of any 
non-payment thereof, Landlord shall have all rights and remedies provided for 
herein or by law for non-payment of rent.

     (B)  All payments of Fixed Rent and additional rent to be made by Tenant 
pursuant to this lease shall be made by checks drawn upon a New York City 
bank which is a member of the New York Clearing House Association or any 
successor thereto.

     (C)  If Landlord receives from Tenant any payment less than the sum of 
the Fixed Rent and additional rent then due and owing pursuant to this lease, 
Tenant hereby waives its right, if any, to designate the items to which such 
payment shall be applied and agrees that Landlord in its sole discretion may 
apply such payment in whole or in part to any Fixed Rent, any additional rent 
or to any combination thereof then due and payable hereunder.

     (D)  Unless Landlord shall otherwise expressly agree in writing, 
acceptance of Fixed Rent or additional rent from anyone other than Tenant

Landlord's rights or Tenant's obligations under this lease.

     (E)  Landlord's failure to timely bill all or any portion of any amount 
payable pursuant to this lease for any period during the Term shall neither 
constitute a waiver of Landlord's right to ultimately collect such amount or 
to bill Tenant at any subsequent time retroactively for the entire amount so 
unbilled, which previously unbilled amount shall be payable within thirty 
(30) days after being so billed.

39.  TAX ESCALATION

     (A)  For purposes hereof:

          (1)  "Real Estate Taxes" shall mean all the real estate taxes and 
assessments imposed by any governmental authority having jurisdiction upon 
the Building and land upon which it is located ("Land") or any tax or 
assessment hereafter imposed in whole or in part in substitution for such 
real estate taxes and/or assessments.

          (2)  "Base Year Taxes" shall mean the Real Estate Taxes as finally 
determined for the Base Tax Year.

          (3)  "Subsequent Tax Year" shall mean any tax fiscal year 
commencing after the expiration of the Base Tax Year.

     (B)  If the Real Estate Taxes for any Subsequent Tax Year during the 
Term exceed the Base Year Taxes (as initially imposed, if not finally 
determined when a payment is due pursuant to Section (C)), Tenant shall pay 
Landlord Tenant's Proportionate Share of such excess within fifteen (15) days 
after Landlord shall furnish to Tenant a statement setting forth the amount 
thereby due and payable by Tenant. If Real Estate Taxes are payable by 
Landlord to the applicable taxing authority in installments, then Landlord 
shall bill Tenant for Tenant's Proportionate Share of the Real Estate Taxes 
in corresponding installments, such that Tenant's payment is due not more 
than fifteen (15) days prior to the date when Landlord is obligated to pay 
the Real Estate Taxes to the applicable taxing authority. If the actual 
amount of Real Estate Taxes are not known to Landlord as of the date of 
Landlord's statement, then Landlord may nevertheless bill Tenant for such 
installment on the basis of a good faith estimate, in which event Tenant 
shall pay the amount so estimated within fifteen (15) days after receipt of 
such bill, subject to prompt refund by Landlord, or payment by Tenant, upon a 
supplemental billing by Landlord once the amount actually owed by Tenant is 
determined. Upon Tenant's request, Landlord shall provide Tenant with a copy 
of the current tax bill used in the preparation of the statement.

     (C)  If the Base Year Taxes ultimately are less than the Real Estate 
Taxes initially imposed upon the Land and the Building for the Base Tax Year, 
Tenant shall pay Landlord, promptly upon demand, any additional amount 
thereby payable pursuant to Section (B) for all applicable Subsequent Tax 
Years.

     (D)  If Landlord receives any refund of Real Estate Taxes for any 
Subsequent Tax Year for which Tenant has made a payment pursuant hereto, 
Landlord shall (after deducting from such refund all expenses incurred in 
connection therewith) pay Tenant, if not in default hereunder, Tenant's 
Proportionate Share of the net refund. If Landlord succeeds in reducing any 
assessed valuation for the Land and the Building prior to the billing of Real 
Estate Taxes for any Subsequent Tax Year, Tenant shall pay Landlord Tenant's 
Proportionate Share of the expenses so incurred by Landlord.

<PAGE>

     (E)  If any Subsequent Tax Year is only partially within the Term, all 
payments pursuant hereto shall be appropriately prorated, based on the 
portion of the Subsequent Tax Year which is within the Term. Except as 
limited by Articles 9 and 10: (i) Tenant's obligation to make the payments 
required by Sections (B), (C) and (D) shall survive the Expiration Date or 
any sooner termination of this lease; and (ii) Landlord's obligation to make 
the payments required by Section (D) shall survive the Expiration Date or 
any sooner termination of this lease pursuant to Articles 9 and 10.

40.  EXPENSE ESCALATION

     (A)  For purposes of the formula and other provisions set forth in this 
Article and elsewhere in this lease:

          (i)   "Rate" shall mean the minimum regular hourly wage rate, 
including adjustments of every kind and nature (including, without 
limitation, all sums paid for Fringe Benefits, as hereinafter defined) 
prescribed for Porters (as hereinafter defined) for Class A office buildings 
(or any successor category), pursuant to the present and any successor 
agreement between the Realty Advisory Board on Labor Relations, Inc. (or any 
successor thereto) and Local 32B-32J of the Service Employees International 
Union, AFL-CIO (or any successor thereto), covering the wage rates for 
Porters in such buildings ("Agreement"), provided, however, that, (a) if, at 
any time during the Term, regular employment of Porters occurs on days or 
during hours when overtime or other premium pay rates are in effect pursuant 
to the Agreement, "Rate" shall mean the average hourly wage rate, including 
adjustments of every kind and nature (including, without limitation, Fringe 
Benefits) for the hours in a calendar week during which Porters are regularly 
employed (e.g., if, pursuant to the Agreement, the regular weekly employment 
of Porters is for forty hours, at a regular hourly wage rate, including  
Fringe Benefits, of $12.00 for the first thirty hours and an overtime hourly 
wage rate, including Fringe Benefits, of $15.00 for the remaining ten hours, 
the average hourly wage rate, including Fringe Benefits, for the applicable 
period shall, before adjustment pursuant to the provisions of subdivision (v) 
of this Section (A), be the weekly wage rate of $510.00, divided by the 
number of regular hours of employment, to wit, forty, or $12.75), and that, 
(b) if, at any time during the Term, no Agreement exists, Rate shall mean the 
average minimum regular hourly wage rate, including adjustments of every kind 
and nature (including, without limitation, Fringe Benefits) actually payable 
to Porters by Landlord or the contractor performing cleaning services in the 
Building, or, if no Porters are employed at the Building, such rate for 
Porters employed at Class A office buildings (as such buildings are presently 
described in the Agreement).

          (ii)  "Base Rate" shall mean the Rate in effect during the Base 
Labor Month.

          (iii) "Porters" shall mean those employees engaged in the general 
maintenance and operation of office buildings, classified as "Others" in the 
current Agreement, who have been employed for ten (10) years or more, or 
failing such classification in any subsequent Agreement, the most nearly 
comparable classification in such Agreement.

          (iv)  "Fringe Benefits" shall mean all direct or indirect costs or 
amounts paid, payable for, allocable to or incurred with respect to so-called 
"fringe benefits" (whether in the form of payments made or accrued, actual or 
potential reductions in time actually worked or otherwise), including, 
without limitation, such costs or amounts for any and all of (a) pensions, 
welfare funds, training funds and dues, (b) social security, vacations, sick 
pay, holidays, jury duty, medical checkup, lunch time ?????


<PAGE>

unemployment, workmen's compensation, disability benefits, health, life, 
accident and other types of insurance.

          (v)   In determining the Rate, the Base Rate and/or Fringe Benefits 
on each applicable occasion pursuant to this lease, the Base Rate and the 
Rate (and the hourly cost of Fringe Benefits) shall be calculated on the 
basis of the number of hours which would be actually worked by Porters during 
the applicable calendar year pursuant to the Agreement assuming all time 
which Porters were entitled not to work, if all relevant circumstances 
provided for in the Agreement occurred, actually was not worked [e.g., if the 
Agreement is predicated on a 2,080 hour work, year (40 hours X 52 weeks) and 
Porters are paid for the following time which they are entitled not to work 
if all relevant circumstances provided for in the Agreement occur (Vacation 
- -- 120 hours, Holidays -- 88 hours, Birthday -- 8 hours, Medical Checkup -- 
16 hours, Sick Days -- 80 hours, Disaster Day -- 8 hours and Relief Time -- 
148.5 hours), then the Base Rate and the Rate (and the hourly cost of Fringe 
Benefits, as well) shall be calculated on the basis of Porter's actually 
working 1,611.5 hours (2,080 hours less 468.5 hours)]

     (B)  If, in any period during the Term, the Rate exceeds the Base Rate, 
Tenant shall pay Landlord an amount ("Expense Escalation") equal to the 
product of (1) the Multiplication Factor, multiplied by (2) the Labor Rate 
Multiple, multiplied by (3) the amount by which the Rate exceeds the Base 
Rate. The Expense Escalation shall be appropriately adjusted for any such 
period which is only partially within the Term. The Expense Escalation shall 
be payable in equal monthly installments, commencing with the first 
installment of Fixed Rent due on or after the effective date of any increase 
in the Rate and continuing thereafter until the effective date of any 
subsequent increase, whereupon such installments shall be appropriate 
adjusted. Landlord shall furnish Tenant with a statement itemizing Tenant's 
liability pursuant to this subdivision whenever such liability arises or 
changes. Except as limited by Articles 9 and 10, Tenant's obligation to make 
such payments shall survive the Expiration Date or any sooner termination of 
this lease. Notwithstanding the foregoing, if, by reason of any law, or any 
rule, order, regulation or requirement of any governmental or 
quasi-governmental authority having or asserting jurisdiction (collectively, 
"Law"), an increase in the Rate is reduced or does not take effect, or 
increases in the Rate are limited or prohibited, then, for the period covered 
by the Law ("Law Period"), the applicable increase ("Increase") in the Rate 
for purposes of this Article shall be the Increase in the Rate ("Prior 
Increase") which most immediately preceded the effective date of the Law. The 
Increase shall take effect on the date following the expiration of the period 
for the Prior Increase and an equivalent Increase shall take effect on each 
anniversary of such effective date during the Law Period.

     (C)  Each notice given by Landlord pursuant to Section (B) shall be 
binding upon Tenant unless, within thirty (30) days after its receipt of such 
notice, Tenant notifies Landlord of its disagreement therewith, specifying 
the portion thereof with which Tenant disagrees. Pending resolution of such 
dispute, Tenant shall, without prejudice to its rights, pay all amounts 
determined by Landlord to be due, subject to prompt refund by Landlord 
(without interest) upon any contrary determination.

41.  ESCALATION FOR INCREASES IN UTILITY COSTS

     (A)  As used herein:

          (i)   "Fuel Cost" shall mean Landlord's cost for all fuel 
(including steam and/or oil) used in the operation of the Building.



<PAGE>


          (ii)  "Electricity Cost" shall mean Landlord's cost for all 
electricity used in lighting all the public and service areas of the Building 
and operating all of the service facilities of the Building (as determined by 
an independent electrical engineer or consultant selected by Landlord);

          (iii) "Utilities Cost" shall mean the sum of the Fuel Cost and the 
Electricity Cost; and

          (iv)  "Base Utilities Cost" shall mean the Utilities Cost for the 
initial Utility Year.

     (B)   If the Utilities Cost for any Utility Year shall be greater than 
the Base Utilities Cost, Tenant shall pay Landlord Tenant's Proportionate 
Share of such excess ("Utilities Payment"). Any such liability shall be 
appropriately prorated for the final Utility Year. Tenant's obligation to 
make such payment shall survive the expiration or sooner termination of this 
lease.

     (C)   After the initial Utility Year, Landlord shall forward Tenant an 
itemized statement (""Utilities Statement") of the Base Utilities Cost. 
Thereafter, Landlord shall forward Tenant a Utilities Statement of the 
Utilities Cost for the prior Utility Year and a computation of the amount 
payable by Tenant pursuant to Section (B).

     (D)   With each installment of Fixed Rent payable during the second 
Utility Year, Tenant shall pay Landlord, on account of the amount payable 
pursuant to this Article for such Utility Year, Tenant's Proportionate Share 
of the product of (i) five percent (5%) of the Base Utilities Cost, and (ii) 
one-twelfth) (1/12). Such payments shall be deferred until Landlord forwards 
the applicable Utilities Statement of Base Utilities Cost, whereupon Tenant 
promptly shall pay all deferred payments and thereafter commence such 
payments.

     (E)   With each installment of Fixed Rent payable during and after the 
third Utility Year, Tenant shall pay to Landlord on account of the amount 
payable pursuant to this Article for the then Utility Year,

          (i)   until Landlord forwards the applicable Utilities Statement 
for the preceding Utility Year, the amount of the monthly payment during 
December of such preceding Utility Year; and

          (ii)  after Landlord forwards the applicable Utilities Statement 
for the preceding Utility Year, one-twelfth of the amount payable pursuant to 
Section (B) for such preceding Utility Year.

     (F)   Once Landlord forwards the applicable Utilities Statement for the 
preceding Utility Year, Landlord and/or Tenant, as the case may be, promptly 
shall make the appropriate payment to the other (without interest) of any 
amount overpaid by Tenant or owing to Landlord for such Utility Year based on 
the amount due pursuant to such Utilities Statement and amounts theretofore 
paid by Tenant for such preceding Utility Year.

     (G)   Landlord's Utilities Statement for any Utility Year shall be 
conclusive and binding upon Tenant unless within thirty (30) days after 
receipt of such Utilities Statement, Tenant notifies Landlord that it 
disputes the correctness of the Utilities Statement, specifying the respects 
in which it is claimed to be incorrect. In the event of any such dispute, 
pending the determination thereof, Tenant shall make payment in accordance 
with Landlord's Utilities Statement, without prejudice to its position. If 
such dispute is determined in Tenant's favor, Landlord shall forthwith pay 
Tenant (without interest) the amount so overpaid by Tenant.




<PAGE>



42.   ELECTRICITY

     (A)   Landlord shall furnish up to 12 watts per rentable square foot of 
electric current for Tenant's use in the demised premises upon and subject to 
the terms and conditions set forth in this Article 42. Tenant's consumption 
of electrical energy at the demised premises shall be measured by submeters 
installed by Landlord at Tenant's expense.

     (B)   (i)  From and after the Commencement Date, Tenant shall purchase 
all electric current consumed in the demised premises from Landlord or 
Landlord's designated agent at a rate equal to 108% of Landlord's Average 
Cost (as hereinafter defined) applied to all electricity consumed in the 
demised premises during the applicable billing period, as measured by the 
submeters.

           (ii) "Landlord's Average Cost" for all purposes of this lease 
shall be determined by dividing (y) the total dollar amount billed to 
Landlord for the Building by the public utility company providing electric 
current to the Building (the ""Utility Company") for the relevant billing 
period (including, without limitation, all charges for "demand", fuel, 
"on-peak" and "off-peak" usage, "time of day" usage and any and all other 
relevant adjustments and charges) by (2) the total kilowatt hours consumed by 
the Building for such billing period.

     (C)   Where more than one submeter measures Tenant's consumption of 
electricity, the service rendered through each submeter may be computed and 
billed separately in accordance with the provisions hereof. Bills therefor 
shall be rendered at such times as Landlord may elect and shall be payable on 
demand as additional rent. In the event that such bills are not paid within 
thirty (30) days after the same are rendered, Landlord may, without further 
notice, discontinue the service of electric current to the demised premises 
without releasing Tenant from any liability under this lease and without 
Landlord's agent incurring any liability for any damage or loss sustained by 
Tenant by such discontinuance or service.

     (D)   Landlord shall not in any way be liable or responsible to Tenant 
for any loss, damage or expense which Tenant may sustain or incur if either 
the quantity or character of electric service is changed or is no longer 
available or suitable for Tenant's requirements. Any riser or risers to 
supply Tenant's electrical requirements will upon written request of Tenant, 
be installed by Landlord at the sole cost and expense of Tenant if, in 
Landlord's reasonable judgment, the same are necessary and will not cause 
adverse damage or injury to the Building or the operation thereof or the 
demised premises, cause or create a dangerous or hazardous condition, entail 
excessive or unreasonable alterations, repairs or expense or interfere with 
or disturb other tenants or occupants. In addition to the installation of 
such riser or risers, Landlord will also, at the sole cost and expense of 
Tenant, install all other equipment proper and necessary in connection 
therewith, subject to the aforesaid terms and conditions. Tenant's use of 
electric current shall never exceed the capacity of existing feeders or 
risers to, or wiring installations in, the Building and the demised premises. 
All of such costs and expense shall be paid by Tenant to Landlord within 
fifteen (15) days after rendition of any bill or statement to Tenant therefor.

     (E)   Landlord may discontinue such service of electric current upon 
sixty (60) days notice to Tenant without being liable to Tenant therefor or 
without in any way affecting this lease or the liability of Tenant hereunder 
or causing a diminution of Fixed Rent. Such discontinuance shall not be 
deemed to be a lessening or diminution of service within the meaning of any 
law, rule or regulation now or hereafter enacted, promulgated or issued. In 
the event Landlord gives such notice of discontinuance, Landlord shall permit 
Tenant to receive such service direct






<PAGE>

from the Utility Company, in which event Tenant shall, at its own cost and 
expense, furnish and install all risers, service wiring, switches and other 
equipment necessary for such installation and required by the Utility Company 
and, at its own cost and expense, maintain and keep in good repair all such 
risers, wiring, switches and equipment.

     (F)  Tenant shall make no alterations or additions to the electric 
equipment and/or appliances presently installed in the demised premises 
without the prior written consent of Landlord in each instance. Rigid conduit 
only will be allowed.

     (G)  If any tax is imposed upon Landlord's receipt from the sale or 
resale of electric energy to Tenant by any Federal, State or Municipal 
Authority, where permitted by law, Tenant's pro-rata share of such taxes 
shall be paid by Tenant to Landlord.

     (H)  Anything in Section (B) to the contrary notwithstanding, if the 
Commencement Date shall occur prior to the installation and proper 
calibration of the submeters, then Tenant shall pay Landlord for Tenant's 
consumption of electricity in the demised premises at the rate of $740 per 
month. In addition, if during any time during the Term, it shall be 
determined that the submeters servicing the demised premises were 
malfunctioning, Tenant shall pay Landlord an amount reasonably estimated by 
Landlord's electrical consultant to be the amount that would have been 
payable by Tenant had such malfunction not occurred.

43.  RESTRICTIONS ON USE

     (A)  Anything in Article 2 to the contrary notwithstanding, Tenant shall 
not use or permit all or any part of the demised premises to be used for the: 
(i) storage for purpose of sale of any alcoholic beverage in the demised 
premises; (ii) storage for retail sale of any product or material in the 
demised premises; (iii) conduct of a manufacturing, printing or electronic 
data processing business, except that Tenant may operate business office 
reproducing equipment, electronic data processing equipment and other 
business machines for Tenant's own requirements (but shall not permit the use 
of any such equipment by or for the benefit of any party other than Tenant); 
(iv) rendition of any health or related services, conduct of a school or 
conduct of any business which results in the presence of the general public 
in the demised premises; (v) conduct of the business of an employment agency 
or executive search firm; (vi) conduct of any public auction, gathering, 
meeting or exhibition; (vii) conduct of a stock brokerage office or business; 
and (viii) occupancy of a foreign, United States, state, municipal or other 
governmental body, agency or department or any authority or other entity 
which is affiliated therewith or controlled thereby.

     (B)  Tenant shall not use or permit all or any part of the demised 
premises to be used so as to impair the Building's character or dignity or 
impose any additional burden upon Landlord in its operation.

     (C)  Tenant shall not obtain or accept for use in the demised premises 
floor polishing, lighting maintenance, cleaning or other similar services 
from any party not theretofore approved by the Landlord (which party's 
charges shall not be excessive). Such services shall be furnished only at 
such hours, in such places within the demised premises and pursuant to such 
regulations as Landlord prescribes.

44.  ASSIGNMENT, ETC.

     Supplementing Article 11:

     (A)  Tenant shall neither: (i) publicly advertise for and/or assign, 
sublet or permit the occupancy 

                                      -7-


<PAGE>

of the demised premises at a rental rate less than the rental rate at which 
Landlord is then offering to lease comparable space in the Building; or (ii) 
assign this lease to or sublet to or permit the occupancy of all or any part 
of the demised premises by any other party which is then a tenant, subtenant, 
licensee or occupant of any space in the Building or which has negotiated 
with Landlord for space in the Building within the twelve (12) month period 
preceding the date of Landlord's receipt of Tenant's Notice pursuant to 
Section (B) (nor shall Tenant accept an assignment of a lease or sublet space 
from any tenant, subtenant, licensee or occupant of any space in the 
Building).

     (B)  If Tenant wishes to assign this lease (a transfer of more than a 
fifty percent (50%) beneficial interest in Tenant, whether such transfer 
occurs at one time, or in a series of related transactions, and whether of 
stock, partnership interest or otherwise, by any party in interest being 
deemed an assignment of this lease), sublet all or any part of the demised 
premises or permit the demised premises to be occupied by any other party, 
Tenant shall designate the then rental agent of the Building as Tenant's 
exclusive agent to effect such sublease or assignment in accordance with such 
rental agent's standard rates and rules then in effect. Thereafter, prior to 
such assignment, subletting or occupancy, Tenant shall first notify Landlord 
("Tenant's Notice"), specifying the name of the proposed assignee, subtenant 
or occupant, the name of and character of its business, the terms of the 
proposed assignment, sublease or occupancy (including, without limitation, 
the commencement and expiration dates thereof) and current information as to 
the financial responsibility and standing of the proposed assignee, sublessee 
or occupant and shall provide Landlord with such other information as it 
reasonably requests. If only a portion of the demised premises (not 
constituting an entire floor of the Building) is to be so sublet or occupied, 
Tenant's Notice shall be accompanied by a reasonably accurate floor plan, 
indicating such portion. The portion of the demised premises to which such 
proposed assignment, sublease or occupancy is to be applicable is hereinafter 
referred to as the "Space."

     (C)  Landlord may, within sixty (60) days after its receipt of Tenant's 
Notice, by notice to Tenant ("Landlord's Notice"), require Tenant to (i) 
sublease the Space to Landlord or its nominee, on the terms set forth in 
Section (D), or (ii) terminate this lease as to the Space for the period 
specified in Tenant's Notice, on the terms set forth in Section (E). If 
Tenant's proposed assignment or sublease is for more than fifty percent (50%) 
of the demised premises or the then balance of the Term is three (3) years or 
less, Landlord also may, by Landlord's Notice, terminate this lease as of the 
proposed commencement date for such assignment, sublease or occupancy. If 
Landlord fails to so exercise such options, it shall not unreasonably 
withhold its consent to the proposed assignment, sublease or occupancy, but 
such consent shall be deemed of no effect if such assignment, sublease or 
occupancy is not consummated upon the terms set forth in Tenant's Notice and 
within thirty (30) days after such consent is given.

     (D)  If Landlord requires Tenant to execute a sublease ("Sublease") 
pursuant to clause (C)(i), the Sublease shall be upon the same terms as this 
lease, except for such terms thereof as are inapplicable and except that: (i) 
the term of the Sublease shall be the term specified in Tenant's Notice 
commencing, at Landlord's option, on (a) the commencement date set forth in 
Tenant's Notice, or (b) a date designated by Landlord which shall not be more 
than thirty (30) days after the date of Landlord's Notice; (ii) the Net Rent 
for the Sublease shall be the lesser of (a) the pro rata Net Rent for the 
Space Tenant is then paying Landlord hereunder, or (b) the Net Rent set forth 
in Tenant's Notice; (iii) the Electric Factor for the Sublease shall be the 
lesser of (a) the pro rata portion of the Electric Factor Tenant is then 
paying Landlord hereunder which is allocable to the Space, or (b) the 
Electric Factor set forth in Tenant's Notice;

                                      -8-

(iv)  Tenant's Proportionate Share and the Multiplication Factor for the 
Sublease shall be determined based on the relative sizes of the Space and the 
initial demised premises; (v) the subtenant under the Sublease shall have the 
unrestricted right to assign the Sublease or any interest therein, to further 
sublet all or any part of the Space and/or to make any alterations, 
decorations, additions or improvements in and to the Space (all or any part 
of which may be removed, at Landlord's option, at any time, provided Landlord 
repairs all damage caused by such removal); (vi) Tenant, as sublandlord under 
the Sublease, shall, at its expense: (a) erect all partitions required to 
separate the Space for the remainder of the demised premises and (b) to the 
extent necessitated by the Sublease, install all doors required for 
independent access from the Space to the elevators, lavatories and staircases 
on the floor and install all equipment and facilities (including, without 
limitation, men's and women's toilets) required to comply with all applicable 
laws and regulations of governmental authorities having jurisdiction and to 
enable Landlord to maintain and service the Space and permit the Space to be 
used as an independent unit; (vii) the Sublease shall provide that the 
termination of all or any portion of this lease by merger is not thereby 
intended; and (viii) at the expiration of the Sublease, the Space shall, 
subject to clause (v), be returned to Tenant as then existing.

     (E)   If Landlord requires Tenant to terminate this lease as to the 
Space pursuant to clause (C)(ii), (i) Tenant at its expense shall (a) erect 
all partitions required to separate the Space from the remainder of the 
demised premises and (b) to the extent required by Landlord, install all 
doors required for independent access from the Space to the elevators, 
lavatories and stairwells on the floor and install all equipment and 
facilities (including, without limitation, men's and women's toilets) 
required to comply with all applicable laws and regulations of governmental 
authorities having jurisdiction and to enable Landlord to maintain and 
service the Space and permit the Space to be used as an independent unit, 
and (ii) Landlord and Tenant shall execute and deliver a supplementary 
agreement modifying this lease by eliminating the Space from the demised 
premises for the term specified in Tenant's Notice commencing, at Landlord's 
option, on (a) the commencement date set forth in Tenant's Notice, or (b) a 
date designated by Landlord which shall not be more than thirty (30) days 
after the date of Landlord's Notice, and, for such period, reducing the Fixed 
Rent and additional rent payable hereunder on a pro rata basis.

     (F)   Anything herein to the contrary notwithstanding, Tenant may not 
assign this lease or sublet all or any part of the demised premises prior to 
the expiration of the first year of the Term.

     (G)   No assignment of this lease shall be effective unless and until 
Tenant delivers to Landlord duplicate originals of the instrument of 
assignment (wherein the assignee assumes the performance of Tenant's 
obligations under this lease) and any accompanying documents.

     (H)   In the event of any such assignment, Landlord and the assignee may 
modify this lease in any manner, without notice to Tenant or Tenant's prior 
consent, without thereby terminating Tenant's liability for the performance 
of its obligations under this lease, except that any such modification which, 
in any way, increases any of such obligations shall not, to the extent of 
such increase only, be binding upon Tenant.

     (I)   No sublease of all or any part of the demised premises (except a 
Sublease) shall be effective unless and until Tenant delivers to Landlord 
duplicate originals of the instrument of sublease (containing the provision 
required by Section (J)) and any accompanying documents. Any such sublease 
shall be subject and subordinate to this lease.


                                      - 9 -



<PAGE>



     (J)   Any such sublease shall contain substantially the following 
provisions:

           (i)   "In the event of a default under any underlying lease of all 
or any portion of the premises demised hereby which results in the 
termination of such lease, the subtenant hereunder shall, at the option of 
the lessor under any such lease ("Underlying Lessor"), attorn to and 
recognize the Underlying Lessor as landlord hereunder and shall, promptly 
upon the Underlying Lessor's request, execute and deliver all instruments 
necessary or appropriate to confirm such attornment and recognition. 
Notwithstanding such attornment and recognition, the Underlying Lessor shall 
not (a) be liable for any previous act or omission of the landlord under this 
sublease, (b) be subject to any off-set, not expressly provided for in this 
sublease, which shall have accrued to the subtenant hereunder against said 
landlord, or (c) be bound by any modification of this sublease or by any 
prepayment of more than one month's rent, unless such modification or 
prepayment shall have been previously approved in writing by the Underlying 
Lessor. The subtenant hereunder hereby waives all rights under any present or 
future law to elect, by reason of the termination of such underlying lease, 
to terminate this sublease or surrender possession of the premises demised 
hereby.''

           (ii)   "This sublease may not be assigned or the premises demised 
hereunder further sublet, in whole or in part, without the prior written 
consent of the Underlying Lessor."

     (K)   Landlord's consent to any assignment or sublease shall neither 
release Tenant from its liability for the performance of Tenant's obligations 
hereunder during the balance of the Term nor constitute its consent to any 
(i) further assignment of this lease or of any permitted sublease or (ii) 
further sublease of all or any portion of the premises demised hereunder or 
under any permitted sublease. If a sublease to which Landlord has consented 
is assigned or all or any portion of the premises demised thereunder is 
sublet without the consent of Landlord in each instance obtained, Tenant 
shall immediately terminate such sublease, or arrange for the termination 
thereof, and proceed expeditiously to have the occupant thereunder 
dispossessed.

     (L)   Tenant shall pay to Landlord, promptly upon demand therefor, all 
costs and expenses (including, without limitation, reasonable attorney's fees 
and disbursements) incurred by Landlord in connection with any assignment of 
this lease or sublease of all or any part of the demised premises.

     (M)   If Landlord shall give its consent to any assignment of this lease 
or to any sublease or if Tenant shall otherwise enter into any assignment or 
sublease permitted hereunder, Tenant shall in consideration thereof, pay to 
Landlord, as and when payable to Tenant:

           (i)   in the case of an assignment, sixty-six and two-thirds 
percent (66 2/3%) of all sums and other considerations paid to Tenant by the 
assignee for or by reason of such assignment (including, but not limited to, 
sums paid for the sale of Tenant's fixtures, leasehold improvements, 
equipment, furniture, furnishings or other personal property); and

           (ii)  in the case of a sublease, sixty-six and two-thirds percent 
(66 2/3%) of the amount, if any, by which (a) any rents, additional charges 
or other consideration payable under the sublease to Tenant by the subtenant 
(including, but not limited to, sums paid for the sale or rental of Tenant's 
fixtures, leasehold improvements, equipment, furniture or other personal 
property) exceeds (b) the Fixed Rent and additional rent accruing during 
the term of the sublease in respect of the Space (at the rate per square foot 
payable by Tenant hereunder) pursuant to the terms of this lease.









<PAGE>

45.  BROKERAGE

     Tenant represents that it dealt only with the Broker as broker in 
connection with this lease and Landlord shall pay the Broker's commission 
therefor pursuant to separate agreement. Tenant shall indemnify Landlord 
against any liability and expense (including reasonable attorney's fees) for 
any other brokerage commission or finder's fee based on alleged actions of 
Tenant or its agents or representatives. Tenant's liability hereunder shall 
survive any expiration or termination of this lease.

46.  BUILDING DIRECTORY

     (A)  Landlord shall, upon Tenant's request, list on the Building's 
directory ("Directory") the names of the Tenant, any other party occupying 
any part of the demised premises pursuant hereto and their officers or 
employees, provided the number of Directory lines so provided by Landlord 
does not exceed Tenant's Proportionate Share of the Directory's capacity.

     (B)  The listing of any party's name other than Tenant's shall neither 
grant such party any right or interest in this lease and/or the demised 
premises nor constitute Landlord's consent to any assignment with sublease to 
or occupancy by such party. Such listing may be terminated by Landlord at any 
time, without prior notice. The initial listing(s) in the Directory shall be 
provided by Landlord without charge to Tenant. Thereafter, Tenant shall pay 
Landlord's standard fee for any work performed in connection with any 
additions, deletions or changes to the Directory.

47.  EXCULPATORY CLAUSE

     (A)  Anything herein to the contrary notwithstanding, the liability of 
Landlord and the partners of Landlord for negligence, failure to perform 
lease obligations or otherwise under or in connection with this lease shall 
be limited to their respective interests in the Land and Building. Tenant 
shall neither seek to enforce nor enforce any judgment or other remedy 
against any other asset of Landlord, any partner of Landlord or any party 
that holds any interest in Landlord.

     (B)  In any claim made by Tenant against Landlord alleging that Landlord 
has acted unreasonably where Landlord had an obligation to act reasonably, 
Tenant's sole and exclusive recourse against Landlord shall be an action 
seeking specific performance of Landlord's obligations under this lease.

48.  SUBMISSION TO JURISDICTION, ETC.

     (A)  This lease shall be deemed to have been made in New York County, 
New York, and shall be construed in accordance with the laws of the State of 
New York. All actions or proceedings relating, directly or indirectly, to 
this lease shall be litigated only in courts located within the County of New 
York. Tenant, any guarantor of the performance of its obligations hereunder 
("Guarantor") and their successors and assigns hereby subject themselves to 
the jurisdiction of any state or federal court located within such county, 
waive the personal service of any process upon them in any action or 
proceeding therein and consent that such process be served by certified or 
registered mail, return receipt requested, directed to the Tenant and any 
successor at Tenant's address hereinabove set forth, to Guarantor and any 
successor at the address set forth in the instrument of guaranty and to any 
assignee at the address set forth in the instrument of assignment. Such 
service shall be deemed made two days after such process is so mailed.

     (B)  Whenever any default, request, action or inaction by Tenant causes 
Landlord to incur attorneys' fees and/or any other costs or expenses, Tenant 
agrees that it shall pay and/or
<PAGE>

reimburse Landlord for such fees, costs or expenses within ten (10) days 
after being billed therefor.

     (C)  If any monies owing by Tenant under this lease are paid more than 
fifteen (15) days after the date such monies are payable pursuant to the 
provisions of this lease, Tenant shall pay Landlord interest thereon, at the 
then maximum lawful rate, for the period from the date such monies were 
payable to the date such monies are paid.

     (D)  The submission of this lease to Tenant shall not constitute an 
offer by Landlord to execute and exchange a lease with Tenant and is made 
subject to Landlord's acceptance, execution and delivery thereof.

49.  MODIFICATIONS REQUESTED BY MORTGAGEE

     If any prospective mortgagee of the Land, Building or any leasehold 
interest therein requires, as a condition precedent to issuing its loan, the 
modification of this lease in such manner as does not materially lessen 
Tenant's rights or increase its obligations hereunder, Tenant shall not delay 
or withhold its consent to such modification and shall execute and deliver 
such confirming documents therefor as such mortgage requires.

50.  "AS IS"

     Supplementing Article 21, the demised premises shall be leased to Tenant 
in their "as is" condition on the Commencement Date and Landlord shall not be 
required to perform any work to prepare the demised premises for Tenant's 
occupancy. The taking of possession of the demised premises by Tenant shall 
be conclusive evidence as against Tenant that, at the time such possession 
was so taken, the demised premises and the Building were in good and 
satisfactory condition.

51.  INSURANCE

     During the Term Tenant shall pay for and keep in force general liability 
policies in standard form protecting against any and all liability occasioned 
by accident or occurrence, subject to customary exclusions, such policies to 
be written by recognized and well-rated insurance companies authorized to 
transact business in the State of New York. The minimum limits of liability 
shall be a combined single limit with respect to each occurrence in an amount 
of not less than $5,000,000 for injury (or death) and damage to property. If 
at any time during the Term it appears that public liability or property 
damage limits in the City of New York for premises similarly situated, due 
regard being given to the use and occupancy thereof, are higher than the 
foregoing limits, then Tenant shall increase the foregoing limits 
accordingly. Landlord shall be named as an additional insured in the 
aforesaid insurance policies and the policies shall provide that Landlord 
shall be afforded thirty days prior notice of cancellation of said insurance. 
Tenant shall deliver certificates of insurance evidencing such policies. All 
premiums and charges for the aforesaid insurance shall be paid by Tenant and 
if Tenant shall fail to make such payment when due, Landlord may make it and 
the amount thereof shall be repaid to Landlord by Tenant on demand and the 
amount thereof may, at the option of Landlord, be added to and become a part 
of the additional rent payable hereunder. Tenant shall not violate or permit 
to be violated any condition of any of said policies and Tenant shall perform 
and satisfy the requirements of the companies writing such policies.

52.  BANKRUPTCY

     Without limiting any of the provisions of Articles 16, 17 or 18 hereof, 
if pursuant to the Bankruptcy Code of 1978, as the same may be amended, 
Tenant is permitted to assign this lease in

<PAGE>

disregard of the obligations contained in Articles 11 and 44 hereof, Tenant 
agrees that adequate assurance of future performance by the assignee permitted 
under such Code shall mean the deposit of cash security with Landlord in an 
amount equal to the sum of one year's Fixed Rent then reserved hereunder plus 
an amount equal to all additional rent payable under this lease for the 
calendar year preceding the year in which such assignment is intended to 
become effective, which deposit shall be held by Landlord, without interest, 
for the balance of the Term as security for the full and faithful performance 
of all of the obligations under this lease on the part of Tenant yet to be 
performed. If Tenant receives or is to receive any valuable consideration for 
such an assignment of this lease, such consideration, after deducting 
therefrom (A) the brokerage commissions, if any, and other expenses 
reasonably incurred by Tenant for such assignment and (B) any portion of such 
consideration reasonably designated by the assignee as paid for the purchase 
of Tenant's property in the demised premises, shall be and become the sole 
and exclusive property of Landlord and shall be paid over to Landlord 
directly by such assignee. In addition, adequate assurance shall mean that 
any such assignee of this lease shall have a net worth, exclusive of good 
will, equal to at least fifteen (15) times the aggregate of the Fixed Rent 
reserved hereunder plus all additional rent for the preceding calendar year 
as aforesaid.

53.  LOCAL LAW 5/REQUIRED ALTERATIONS

     Supplementing Article 6,

     (A)  All work performed or installations made by Tenant (or by Landlord 
at Tenant's request and expense) in and to the demised premises shall be done 
in a fashion such that the demised premises and the Building shall be in 
compliance with the requirements of Local Law 5 of 1973 of The City of New 
York, as heretofore and hereafter amended ("Local Law 5"). The foregoing 
shall include, without limitation, (i) compliance with the 
compartmentalization requirements of Local Law 5, (ii) relocation of existing 
fire detection devices, alarm signals and/or communication devices 
necessitated by the alteration of the demised premises, and (iii) 
installation of such additional fire control or detection devices as may be 
required by applicable governmental or quasi-governmental rules, regulations 
or requirements (including, without limitation, any requirements of the New 
York Board of Fire Underwriters) as a result of Tenant's manner of use of the 
demised premises. In addition, Tenant shall cause the demised premises to be 
connected to the Building "Class E" system and arrange to have the demised 
premises and Tenant added to the "Class E" computer.

     (B)  Landlord shall not be responsible for any damage to Tenant's fire 
control or detection devices nor shall Landlord have any responsibility for 
the maintenance or replacement thereof. Tenant shall indemnify Landlord from 
and against all loss, damage, cost, liability or expense (including, without 
limitation, reasonable attorneys' fees and disbursements) suffered or 
incurred by Landlord by reason of the installation and/or operation of any 
such devices.

     (C)  All work and installations required to be undertaken by Tenant 
pursuant to this Article shall be performed at Tenant's sole cost and expense 
and in accordance with plans and specifications and by contractors previously 
approved by Landlord.

     (D)  The fact that Landlord shall have heretofore consented to any 
installations or alterations made by Tenant in the demised premises shall not 
relieve Tenant of its obligations pursuant to this Article with respect to 
such installations or alterations.

     (E)  In the event that any utility company or governmental or 
quasi-governmental authority requires any work, installation


<PAGE>

Alteration performed by Tenant, the installation or operation of equipment or 
machinery in the demised premises or for any other reason relating to 
Tenant's use or occupancy of the demised premises, Tenant shall reimburse 
Landlord for the cost of such work, installation or improvement on demand.

54.  TENANT'S ALTERATIONS

     (A)  Tenant shall not make or perform, or permit the making or 
performance of, any alterations, installations, improvements, additions or 
other physical changes in or about the demised premises (collectively, 
"Alterations") without Landlord's prior consent. Landlord agrees not to 
unreasonably withhold its consent to any Alterations which are nonstructural 
or which do not affect the Building's system and facilities proposed to be 
made by Tenant to adapt the demised premises for those business purposes 
permitted by Article 2 hereof, provided that such Alterations are performed 
only by contractors or mechanics designated by Landlord, do not affect any 
part of the Building other than the demised premises, do not adversely affect 
any service required to be furnished by Landlord to Tenant or to any other 
tenant or occupant of the Building and do not reduce the value or utility of 
the Building. All Alterations shall be done at Tenant's expense and at such 
times and in such manner as Landlord may from time to time reasonably 
designate pursuant to the conditions for Alterations prescribed by Landlord 
for the demised premises. Prior to making any Alterations, Tenant (i) shall 
submit to Landlord detailed plans and specifications (including layout, 
architectural, mechanical and structural drawings) for each proposed 
Alteration and shall not commence any such Alteration without first obtaining 
Landlord's approval of such plans and specifications, (ii) shall, at its 
expense, obtain all permits, approvals and certificates required by any 
governmental or quasi-governmental bodies, and (iii) shall furnish to 
Landlord duplicate original policies of worker's compensation insurance 
(covering all persons to be employed by Tenant, and Tenant's contractors and 
subcontractors in connection with such Alteration) and comprehensive public 
liability (including property damage coverage) insurance in such form, with 
such companies, for such periods and in such amounts as Landlord may 
reasonably require, naming Landlord and its agents as additional insureds. 
Upon completion of such Alteration, Tenant, at Tenant's expense, (a) shall 
obtain certificates of final approval of such Alteration required by any 
governmental or quasi-governmental bodies and shall furnish Landlord with 
copies thereof and (b) shall deliver to Landlord "as built" plans and 
specifications for such Alteration within thirty (30) days of the completion 
thereof. All Alterations shall be made and performed in accordance with the 
Rules and Regulations: all materials and equipment to be incorporated in the 
demised premises as a result of all Alterations shall be new and first 
quality; no such materials or equipment shall be subject to any lien, 
encumbrance, chattel mortgage, title retention or security agreement. Tenant 
shall not, at any time prior to or during the Term, directly or indirectly 
employ, or permit the employment of, any contractor, mechanic or laborer in 
the demised premises, whether in connection with any Alteration or otherwise, 
if, in Landlord's sole discretion, such employment will interfere or cause any 
conflict with other contractors, mechanics, or laborers engaged in the 
construction, maintenance or operation of the Building by Landlord, Tenant or 
others. In the event of any such interference or conflict, Tenant, upon 
demand of Landlord, shall cause all contractors, mechanics or laborers 
causing such interference or conflict to leave the Building immediately.

     (B)  No approval of any plans or specifications by Landlord or consent 
by Landlord allowing Tenant to make any Alterations or any inspection of 
Alterations made by or for Landlord shall in any way be deemed to be an 
agreement by Landlord that the contemplated Alterations comply with any legal 
requirements or insur-


<PAGE>

ing nor shall it be deemed to be a waiver by Landlord of the compliance by 
Tenant of any provision of this lease.

     (C)  Tenant shall promptly reimburse Landlord for all fees, costs and 
expenses including, but not limited to, those of attorneys, architects and 
engineers, incurred by Landlord in connection with inspecting the Alterations 
to determine whether the same are being or have been performed in accordance 
with the approved plans and specifications therefore and with all legal 
requirements and insurance requirements.

55.  ESTOPPEL CERTIFICATE

     Tenant, at any time, and from time to time, upon at least ten (10) days' 
prior notice by Landlord, shall execute, acknowledge and deliver to Landlord, 
and/or to any other person, firm or corporation specified by Landlord 
("Recipient"), a statement certifying that this lease is unmodified and in 
full force and effect (or, if there have been modifications, that the same is 
in full force and effect modified and stating the modifications), stating the 
dates to which the Fixed Rent and additional rent have been paid, stating 
whether or not there exists any defaults by Landlord under this lease, and, if 
so, specifying each such default and any other matters reasonably requested 
by Landlord or the Recipient.

56.  HOLDOVER

     In the event Tenant shall hold over after the expiration of the Term, 
the parties hereby agree that Tenant's occupancy of the demised premises 
after the expiration of the Term shall be upon all of the terms set forth in 
this lease except Tenant shall pay as use and occupancy charge for the 
holdover period an amount equal to the higher of (A) an amount equal to two 
times the sum of (1) the pro rata Fixed Rent payable by Tenant during the 
last year of the Term and (2) all monthly installments of additional rent 
payable by Tenant pursuant to the terms of this lease that would have been 
billable monthly by Landlord had the Term not expired; or (B) an amount equal 
to the then market rental value for the demised premises as shall be 
established by Landlord giving notice to Tenant of Landlord's good faith 
estimate of such market rental value.

57.  CONDITIONAL LIMITATION

     In the event that twice in any twelve (12) month period (A) a default of 
the kind set forth in Section 17(1) shall have occurred or (B) Tenant shall 
have defaulted in the payment of Fixed Rent or additional rent, or any part 
of either, and Landlord shall have commenced a summary proceeding to 
dispossess Tenant in each such instance, then, notwithstanding that such 
defaults may have been cured at any time after the commencement of such 
summary proceeding, any further default by Tenant within such twelve (12) 
month period shall be deemed to be a violation of a substantial obligation of 
this lease by Tenant and Landlord may serve a written three (3) days' notice 
of cancellation of this lease upon Tenant and, upon the expiration of said 
three (3) days, this lease and the Term shall end and expire as fully and 
completely as if the expiration of such three (3) day period were the day 
herein definitely fixed for the end and expiration of this lease and the Term 
and Tenant shall then quit and surrender the demised premises to Landlord, 
but Tenant shall remain liable as elsewhere provided in this Lease.

58.  LIMITATION ON RENT

     If on the Commencement Date, or at any time during the Term, the Fixed 
Rent or additional rent reserved in this lease is not fully collectible by 
reason of any Federal, State, County or City law, proclamation, order or 
regulation, or direction of as public officer or body pursuant to law 
(collectively, "Law"), Tenant 


<PAGE>

agrees to take such steps as Landlord may request to permit Landlord to 
collect the maximum rents which may be legally permissible from time to time 
during the continuance of such legal rent restriction (but not in excess of 
the amounts reserved therefor under this lease). Upon the termination of such 
legal rent restriction, Tenant shall pay to Landlord, to the extent permitted 
by Law, an amount equal to (A) the Fixed Rent and additional rent which would 
have been paid pursuant to this lease but for such legal rent restriction, 
less (B) the Fixed Rent and additional rent paid by Tenant to Landlord during 
the period such legal rent restriction was in effect.

59.  ACCEPTANCE OF KEYS

     If Landlord or Landlord's managing or rental agent accepts from Tenant 
one or more keys to the demised premises in order to assist Tenant in showing 
the demised premises for subletting or other disposition or for the the 
performance of work therein for Tenant or for any other purpose, the 
acceptance of such key or keys shall not constitute an acceptance of a 
surrender of the demised premises nor a waiver of any of Landlord's rights or 
Tenant obligations under this lease including, without limitation, the 
provisions relating to assignment and subletting and the condition of the 
demised premises.

60.  SECURITY DEPOSIT

     Supplementing Article 34:

     Tenant may, at the execution of this lease or at any time during the 
Term, substitute for the Security Deposit an irrevocable letter of credit 
(the "Letter of Credit") in the amount of the Security Deposit issued by a 
New York City commercial bank acceptable to Landlord in its discretion, and 
in the form of the letter of credit annexed thereto as Exhibit B, to be held 
by Landlord as security in accordance with Article 34 and this Article 60.  
The Letter of Credit shall (i) initially expire not less than one (1) year 
from the Commencement Date or the date of issuance if delivered to Landlord 
thereafter, (ii) provide for automatic renewals for periods of not less than 
one (1) year, and (iii) have a final expiration date not less than four (4) 
months after the Expiration Date. Tenant shall pay to landlord, on demand and 
as additional rent hereunder, all fees and charges paid by landlord to the

<PAGE>

                                AMENDMENT OF LEASE

     This Amendment of Lease (this "Agreement"), dated as of the 30th day of 
April, 1997, between HUDSON TELEGRAPH ASSOCIATES, a New York limited 
partnership having an address c/o Williams Real Estate Co. Inc., 530 Fifth 
Avenue, New York, New York 10036 ("Landlord") and T-ONE CORP., a Delaware 
corporation having an address at 60 Hudson Street, New York, New York 10013 
("Tenant").

                               W I T N E S S E T H:

     WHEREAS:

     A.  Landlord and Tenant entered into a lease dated as of February 17, 
1993 (the "Existing Lease") pursuant to which Tenant leased a portion of the 
3rd floor known as Room 316 (the "Existing Premises") in the building known 
as 60 Hudson Street, New York, New York (the "Building").

     B.  Landlord and Tenant wish to increase the premises demised under the 
Existing Lease by adding thereto the premises shown hatched on Exhibit A 
annexed hereto (the "New Premises") and to make certain other changes in the 
Existing Lease.

     NOW, THEREFORE, in consideration of the foregoing and the mutual 
covenants hereinafter contained, Landlord and Tenant agree that the Existing 
Lease is hereby amended as follows:

     1.  All terms contained in this Agreement shall, for the purposes 
hereof, have the same meanings ascribed to them in the Existing Lease unless 
otherwise defined herein. As used herein, the term "Lease" shall mean the 
Existing Lease as amended by this Agreement and as hereafter amended.

     2.  Effective as of the date hereof (the "New Premises Date"), the 
"premises" or "demised premises" shall be the Existing Premises plus the New 
Premises. Landlord and Tenant mutually acknowledge, without making any 
representation, that for all purposes of the Lease the New Premises shall be 
deemed to contain 2,497 rentable square feet.

     3.  Commencing on the New Premises Date, the annual Fixed Rent payable 
under the Lease shall be increased by $57,431 per annum. Notwithstanding the 
foregoing, provided the Lease is in full force and effect and Tenant is not 
in default thereunder beyond any applicable notice and grace period, the 
additional Fixed Rent due with respect to the New Premises (I.E., $57,431 per 
annum) shall abate from the New Premises Date to and including September 30, 
1997.

<PAGE>

     4.  Landlord makes no representations concerning the condition of the 
New Premises or the equipment, if any, located therein. Tenant agrees to 
accept the New Premises in their "as is" condition on the New Premises Date. 
Landlord shall not be required to perform any work to prepare the New 
Premises for Tenant's occupancy. Tenant understands that, although there 
exists duct-work to which an air-conditioning system may be attached (which 
duct-work, in its "as is" condition, Tenant will be permitted to use), there 
is no air-conditioning system presently serving the New Premises. Subject to 
Tenant's compliance with all the applicable provisions of the Lease, Tenant 
will be permitted to install and maintain, at Tenant's sole expense, an 
air-conditioning system in the New Premises.

     5.  It is the intention of the parties that additional rent payable by 
Tenant pursuant to the Lease be calculated separately for the Existing 
Premises and the New Premises, with the calculations for the Existing 
Premises being made pursuant to the provisions of Articles 37, 39, 40 and 41 
of the Existing Lease as unmodified by this Agreement and the calculations 
for the New Premises being made pursuant to the provisions of Articles 37, 
39, 40 and 41 the Existing Lease with the following modifications:

         (a)  "Base Tax Year" for the New Premises shall mean the calendar 
year 1997 and therefore "Base Year Taxes" for the New Premises shall mean 
one-half of the Real Estate Taxes for tax fiscal year July 1, 1996 - June 30, 
1997 plus one-half of the Real Estate Taxes for tax fiscal year July 1, 1997 
- - June 30, 1998.

         (b)  "Tenant's Proportionate Share" for the New Premises shall mean 
0.30%;

         (c)  "Base Labor Month" for the New Premises shall mean January, 1997;

         (d)  "Multiplication Factor" for the New Premises shall mean 2,497; 
and           

         (e)  "Base Utilities Cost" for the New Premises shall mean the 
Utilities Cost for calendar year 1997.

     6.  Landlord shall furnish, at a location designated by Landlord, for 
Tenant's use in the New Premises, up to twelve (12) watts of electric current 
per rentable square foot contained in the New Premises upon and subject to 
the terms and conditions set forth in Article 42 of the Lease. In bringing 
such current from such designated location to the New Premises, Tenant shall 
use only such electrical contractors as are then on the approved list for the 
Building. Any additional current required by Tenant shall be provided by 
Landlord, if available, at a cost of $150.00 per amp if provided during the 
twelve (12) month period after the

                                      -2-
<PAGE>


date hereof, and if later provided, then at Landlord's standard charge. If at 
any time during the Term, whether before or after Tenant's power is increased 
or decreased, Landlord reasonably determines that Tenant is not using any 
portion of the electric capacity then servicing the demised premises, then 
Landlord shall have the right to recapture any such power not then being used 
by Tenant without compensation to Tenant. Tenant's consumption of energy in 
the New Premises will be measured by a submeter to be installed by the 
Landlord at Tenant's expense. Anything in the Lease to the contrary 
notwithstanding, if the New Premises Date occurs prior to the installation 
and proper calibration of the submeter, then (i) Tenant shall pay Landlord 
for Tenant's consumption of electricity in the New Premises at the rate of 
$312 per month during any period when construction is taking place in the 
New Premises; and (ii) from and after the date on which Tenant occupies all 
or a portion of the New Premises for the conduct of business and until the 
installation and proper calibration of the submeter, Tenant shall pay 
Landlord $624 per month on account, such payments to be retroactively 
adjusted based on the average kilowatts and kilowatt hours consumed over the 
first three (3) months after installation and proper calibration of the 
submeter. In addition, if, during any time during the Term, it shall be 
determined that the submeter(s) servicing the demised premises were 
malfunctioning, or if Tenant's power is increased prior to the installation 
and proper calibration of any required additional meters, Tenant shall pay 
Landlord an amount reasonably estimated by Landlord's electrical consultant 
to be the amount that would have been payable by Tenant had such malfunction 
not occurred or had the additional power been properly metered, as the case 
may be.

     7.  Simultaneously with the execution of this Agreement, Tenant has 
delivered to Landlord a check subject to collection in the amount of $28,715, 
increasing the amount of the Security Deposit to $50,715.

     8.  Landlord acknowledges that the business to be conducted by Tenant in 
the demised premises requires the installation of certain communications 
equipment owned by customers of Tenant in the demised premises, in order for 
such customers to interconnect with Tenant's terminal facilities. Landlord 
expressly agrees that Tenant may license the use of portions of the demised 
premises to its customers solely for the purpose of locating equipment therein 
without Landlord's further consent; provided, however, that such license 
shall be granted only upon the execution by Tenant and its customers of an 
agreement that expressly provides that (i) such license and the rights of such 
licensee shall at all times be subordinate to this lease and shall not be 
binding on Landlord; (ii) such license will expire no later than the day 
prior to the expiration or earlier termination of this lease; and (iii) such 
license shall be for equipment only and shall not grant to the licensee the 
right to occupy any portion of the Building or the demised


                                     -3-


<PAGE>


premises. Copies of any such agreements shall be delivered to Landlord with 
reasonable promptness after execution.

     9.  The covenants, agreements, terms and conditions contained in this 
Agreement shall bind and inure to the benefit of the parties hereto and their 
respective successors, and, except as otherwise provided in the Lease, their 
respective assigns.

     10.  Except as amended by this Agreement, the Lease and all covenants, 
agreements, terms and conditions thereof shall remain in full force and 
effect and the Lease, as so amended, is hereby in all respects ratified and 
confirmed.

     11.  Tenant covenants, represents and warrants that Tenant has had no 
dealings or communications with any broker or agent in connection with the 
consummation of this Agreement other than Williams Real Estate Co. Inc. (the 
"Broker"). Landlord agrees to pay a commission to the Broker pursuant to a 
separate agreement. Tenant covenants and agrees to indemnify Landlord from 
and against all costs, expenses (including reasonable attorneys' fees and 
disbursements) and liability for any commission or other compensation claimed 
by any broker or agent (other than Broker) with respect to this Agreement.

     12.  This Agreement may not be changed orally, but only by a writing 
signed by the party against whom enforcement thereof is sought.

    13.  The submission of this Agreement to Tenant shall not constitute an 
offer by Landlord to execute and exchange this Agreement with Tenant and is 
made subject to Landlord's acceptance, execution and delivery thereof.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement as 
of the day and year first above written.

                    AMENDMENT NUMBER THREE TO EMPLOYMENT AGREEMENT

     THIS AMENDMENT NUMBER THREE TO EMPLOYMENT AGREEMENT (this "Amendment") 
is effective as of July 1, 1997, between STAR TELECOMMUNICATIONS, INC., a 
Delaware corporation ("STAR"), as successor in interest to STAR Vending, 
Inc., a Nevada corporation, and MARY CASEY ("EXECUTIVE").

                                       RECITALS

     A.   Star and Executive are parties to that certain Employment 
Agreement dated July 14, 1995 (the "Employment Agreement"), that certain 
Amendment Number One to Employment Agreement dated January 1, 1996 
("Amendment Number One"), and that certain Amendment Number Two to 
Employment Agreement dated July 15, 1996 ("Amendment Number One"), pursuant 
to which Executive is employed by Star.

     B.   The parties desire to adjust Executive's compensation and extend 
the expiration date of the Employment Agreement, and thus have determined to 
amend the Employment Agreement as set forth in this Amendment.

                                       AGREEMENTS

     NOW, THEREFORE, the parties agree to amend the Employment Agreement as 
follows:

     1.   DEFINED TERMS. Capitalized terms used in this Amendment and not 
otherwise defined shall have the meanings ascribed to them in the Employment 
Agreement, Amendment Number One, and Amendment Number Two. From and after the 
date hereof, the term "Agreement" as used in the Employment Agreement will 
mean the Employment Agreement as amended by Amendment Number One, Amendment 
Number Two, and this Amendment, unless and until such Employment Agreement 
may again be amended.

     2.   AMENDMENT OF SECTION 3. Section 3 of the Employment Agreement 
shall be amended to read in its entirety as follows:

    "3.  TERM. The term of Executive's employment by Star pursuant to this 
    Agreement shall be for the period commencing July 14, 1995 and ending 
    December 31, 2000. The term of Executive's employment is subject to earlier 
    termination as provided in Section 7."

     3.   AMENDMENT OF SECTION 4.1 Section 4.1 of the Employment Agreement 
shall be amended to read in its entirety as follows:

    "4.1  SALARY. Star shall pay Executive a monthly salary during the term of 
    this Agreement. This salary shall be $20,000 per month effective July 1, 
    1997. Executive's monthly salary shall be increased for the respective 
    calendar years commencing January 1, 1998, January 1, 1999, and January 1, 
    2000, as follows: 

          "(a)   Before January 30, 1998, the parties shall ascertain from the
     official Consumers Price Index for All Urban Wage Earners and Clerical 
     Workers (Revised Series), Los Angeles-Anaheim-Riverside Average
     (1982-1984 = 100), as published by the Bureau of Labor Statistics,
     Department of Labor (the "Index"), the Index for December 1996 (the "Base
     Period Index") and for December 1997 (the "Comparison Period Index"). If
     the Comparison Period Index exceeds the Base Period Index, the monthly
     salary payable by Star to Executive for the entire calendar year 1998
     shall be increased (but not decreased) by multiplying Executive's
     then-existing monthly salary by a fraction, the numerator of which shall
     be the Comparison Period Index and the denominator of which shall be the
     Base Period Index. If the Comparison Period Index does not exceed the Base

                                       -1-




<PAGE>

     Period Index, the monthly minimum salary payable to Executive by Company 
     during calendar 1998 shall remain at the monthly salary effective as of 
     December 31, 1997.

          (b)   A similar adjustment shall be made to Executive's monthly 
     salary for calendar years 1999 and 2000; but for the purpose of such 
     adjustments, the Base Period Index shall be calculated as of December,
     1997 and 1998, respectively, and the Comparison Period Index shall be
     calculated as of December 1998 and 1999, respectively.

          (c)   If the Index is no longer published, then appropriate index 
     figures for the Base Period Index and the Comparison Period Index shall be
     derived from any successor or comparable index mutually agreed by the
     parties to be authoritative.

          (d)   The parties acknowledge that the Comparison Period Index 
     figures for each year of the Employment Agreement may not be available in a
     timely manner. Therefore, the monthly salary in efect during the preceding
     month shall continue in effect until the respective average index figures
     for the Comparison Period Indexes have been ascertained. Upon determination
     of the respective Comparison Period Indexes for each year, an appropriate
     adjustment shall be made, retroactive to January 1 of 1998, 1999, and 2000,
     respectively, and Star shall immediately pay to Executive any increased
     salary found to be due.

          (e)   Executive may receive such other increases in her salary in 
     addition to those set forth above as the Board of Directors of Star may 
     approve from time to time. Executive's salary shall not be reduced at any 
     time during the term of this Agreement, but the foregoing shall not limit 
     Star's rights under Section 7."

     4.   CONFIRMATION. Except as specifically amended by this Amendment, 
the Employment Agreement, Amendment Number One, and Amendment Number Two will 
continue unchanged, and the terms and conditions of the Employment Agreement, 
Amendment Number One, and Amendment Number Two, as amended by this Amendment, 
are ratified and confirmed.

     IN WITNESS WHEREOF, the parties have executed this Amendment effective 
as of the date first set forth above.

                    AMENDED AND RESTATED 1996 STOCK INCENTIVE PLAN

effective March 31, 1996, by the Board of Directors and Shareholders of STAR

                                       RECITALS

     A.   The STAR Vending, Inc. 1996 Stock Incentive Plan was adopted by the

"Original Plan").

     B.   The Original Plan was entirely amended and restated effective March

     C.   The Corporation desires to amend the Restated Plan to provide that the

     NOW, THEREFORE, the Restated Plan is amended to read as follows:

1.   SECTION 6.12.  Section 6.12 is deleted in its entirety and replaced with
the following new Section 6.12:

     "6.12 ACCELERATION.

          (a)  A "Change in Control" for purposes of this Plan shall be
     deemed to have occurred if, after the date of adoption of this Plan,
     (i) a single entity or group of affiliated entities acquires more than
     50% of the stock of the Company issued and outstanding immediately
     prior to such acquisition; or (ii) shareholders approve the
     consummation of any merger of the Company, if the shareholders of the
     Company immediately before such transaction own, immediately after
     consummation of such transaction, equity securities (other than
     options and other rights to acquire equity securities) possessing


                                         -1-

<PAGE>

     less than 50% of the voting power of the surviving or acquiring
     corporation; or (iii) shareholders approve the consummation of any
     sale or other disposition of all or substantially all of the assets of
     the Company.

          (b)  If a Change in Control has occurred or if the Board of
     Directors determines in good faith that a Change in Control is about
     to occur, the Board of Directors may determine that it is necessary or
     desirable to accelerate the exercisability of all options granted
     hereunder. Upon such determination, the Board of Directors shall
     establish the date upon which all options not theretofore exercisable
     shall become exercisable, the period of time (not in excess of 10
     days) during which such options may be exercised and the notice
     required for exercise. The Board of Directors shall notify all
     optionees of such date, exercise period and notice requirement.

          (c)  Any options subject to acceleration under this Section that
     are not exercised during the exercise period established by the Board
     of Directors pursuant to subsection (b) above shall be treated as if
     no Change in Control had occurred and shall be governed by their
     original terms. Nevertheless, by a notice to that effect which is
     communicated in any reasonable manner to as many of the holders of
     options as is feasible, the Board of Directors may provide that any
     options accelerated pursuant to this Section 6.12 shall expire at the
     end of the exercise period established by the Board of Directors
     pursuant to subsection (b).

          (d)  In the event of a Change in Control that consists of a
     merger of the Company with or into another entity in which holders of
     the Company's common stock will receive cash for their shares, the
     Board of Directors, upon making the determination set forth in
     subsection (b) may provide that, upon consummation of such Change in
     Control, all then outstanding options granted hereunder shall be
     automatically converted into the right to receive cash in an amounts
     equal to the difference, if any, between the price to be received by
     holders of the Company's common stock for their shares and the
     respective Exercise Prices of the outstanding options.

          (e)  Except as set forth in this subsection (e), if a Change in
     Control occurs, and the Board of Directors does not make the
     determination set forth in subsection (b) above, the exercisability of
     the then-outstanding options of the Company granted under this Plan
     shall not be affected. The foregoing notwithstanding, any options held
     by an optionee whose employment with the Company (or any Subsidiary or
     Parent) is terminated by the Company


                                         -2-

<PAGE>

     other than for cause within one year after such Change in Control
     shall be deemed to be fully exercisable as of the date of such
     termination of employment. Nothing in this subsection (e) shall limit
     or affect the provisions of Section 6.4 of this Plan."

2.   CONFIRMATION.  In all other respects, the provisions of the Restated Plan
shall remain unchanged.

and without deduction of any withholding taxes.  Withholding taxes are taxes,
duties or governmental charges of any kind whatsoever which are imposed or
levied in, by or on behalf of the country in which we are/or the Borrower is
situated, and which are deducted from any payment hereunder and/or under the
Agreement.  If the deduction of withholding taxes is required by law, then we
shall pay such additional amounts as may be necessary in order that the net
amounts received by you after such deduction shall equal the amount that would
have been receivable had no such deduction been required.

7.   CURRENCY INDEMNITY.  Payments made by us to you pursuant to a judgement or
order of a court or tribunal in a currency other than that of the Guarantee (the
"Guarantee Currency") shall constitute a discharge of our obligation hereunder
only to the extent of the amount of the Guarantee Currency that you, immediately
after receipt of such payment in such other currency, would be able to purchase
with the amount so received on a recognised foreign exchange market.  If the
amount so received should be less than the amount due in the Guarantee Currency
under this Guarantee, then as a separate and independent obligation, which gives
rise to a separate cause of action, we are obliged to pay the difference.

8.   LIMITATION OF SUBROGATION.  So long as any sum remains payable under the
Agreement, we undertake not to assert any claim we may have against the Borrower
by reason of the performance of our obligations under this Guarantee, whether on
contractual grounds or on any other legal basis, until all amounts payable to
you under the Agreement have been fully and irrevocably received or recovered.
Any amount received or recovered by us from the Borrower shall be held in trust
for and immediately paid to you.  If we make any payment to you hereunder.

<PAGE>

                                          4

we shall only be subrogated in your rights against the Borrower once all amounts
payable to you under the Agreement have been fully and irrevocably received or
recovered by you.

9.   DISSOLUTION/CHANGE OF STRUCTURE. The obligations under this Guarantee 
shall remain in force notwithstanding any dissolution or change in the 
structure or legal form of the Borrower.

10.  RESTRUCTURING. You shall without our consent be entitled to reschedule or
restructure principal, interest and other amounts payable under the Agreement,
to release the Borrower from its obligations and/or to accept a new debtor if,
for reasons which you deem important, you or other companies of the Deutsche
Bank group agree to similar measures also with respect to your or their other
credits extended to entities in the country of the Borrower. Our liability under
this Guarantee shall not be affected by such measures, and we undertake to pay
to you upon first demand, in accordance with the terms hereof, all such amounts
in full and at such time as they would have become due and payable had the
Agreement and the Indebtedness remained effective and unaltered. Our consent to
the terms and documentation of such rescheduling, restructuring, release or debt
assumption shall not be required.

11.  NEW MONEY. Should you agree, in connection with a debt restructuring or in
order to avoid such restructuring, to extend new credits ("New Money") to the
Borrower or other entities of the public or private sector in the country of the
Borrower and should your participation in such New Money be calculated on the
basis of credits extended by you and/or other companies of the Deutsche Bank
group to the Borrower or such other entities, we hereby irrevocably and
unconditionally guarantee, in accordance with the terms hereof, that portion of
the claims for principal, interest, cost, expenses, fees and other amounts
payable in respect of the New Money by which your participation in the New Money
is increased

<PAGE>

                                          5

by virtue of the Indebtedness, regardless of whether you are legally obliged to
take part in the restructuring or the New Money. Our consent to the terms and
documentation of the New Money shall not be required.

12.  MISCELLANEOUS. We represent and warrant that this Guarantee is binding,
valid and enforceable against us in accordance with its terms. We waive any
express acceptance of this Guarantee by you. We confirm that we have taken, and
will continue to take, all necessary steps to ensure that any amount claimed by
you from us hereunder can be transferred to you immediately, free of any
deduction, cost or charges whatsoever. We waive any right to require information
from you in respect of the Agreement and the Indebtedness. 

13.  TERM. This Guarantee is effective as of its date of issuance [and shall
expire once all amounts expressed to be payable by the Borrower to you under the
Agreement have been fully and irrevocably received by you]. Unless we shall have
received your demand hereunder in accordance with the aforementioned conditions
on or before dezember, 15, 2002, this Guarantee shall expire and be of no
further effect. However, should you thereafter become liable to return monies
received in payment of the Indebtedness as a result of any bankruptcy,
composition or similar proceedings affecting the Borrower, this Guarantee shall
be reinstated and become effective again notwithstanding such expiration.

14.  PARTIAL INVALIDITY. Should any provision of this Guarantee be unenforceable
or invalid, the other provisions hereof shall remain in force.

                                          6

15.  APPLICABLE LAW, JURISDICTION. This Guarantee and all rights and obligations
arising hereunder shall in all respects be governed by German law. We hereby
submit to the jurisdiction of the competent courts of Friedrichshafen, Germany.
We hereby irrevocably appoint DR. TORSTEN BARTSCH OF DOSER AMERELLER NOACK (fill
in name of the process agent) as our agent for service of process or other legal
summons in connection with any action or proceedings in Germany arising under
this Guarantee. We irrevocably waive any objection which we may now or hereafter
have that such proceedings have been brought in an inconvenient forum.

NUMBER OF EACH REPAYMENT INSTALLMENTS: 37

AMOUNT OF EACH REPAYMENT INSTALLMENT: $13,976.29

AMOUNT OF FINAL REPAYMENT INSTALLMENT: $137,330.15

DUE DATE OF FIRST REPAYMENT INSTALLMENT: On the day Secured Party funds this
loan.

INTEREST RATE. A per annum rate of interest equal to (i) Eight and 83/100
percent (8.83%) or (ii) if less, the highest rate of interest permitted by
applicable law.

LOAN; TERMS OF REPAYMENT. In consideration of the making of a loan by Secured
Party to Debtor for the purpose of financing the Equipment specified above (the
"Loan"), Debtor promises and agrees to pay to the order of Secured Party, at
Secured Party's address stated above or at such other places as Secured Party
may from time to time designate in writing, the principal amount of the Loan,
together with interest calculated as hereinafter provided. Subject to Debtor's
right to prepay such principal amount in whole or in part as hereinafter
provided, Debtor shall pay such principal amount together with interest thereon
in consecutive monthly installments, each in the amount set forth above under
the heading "Amount of Each Repayment Installment," due and payable on the "Due
Date of First Repayment Installment" set forth above and continuing on a like
date of each calendar month thereafter until the Loan is fully repaid; provided,
however, that the last such installment shall be in the amount of the then
outstanding principal balance of the Loan together with interest thereon.

INTEREST. Interest shall be calculated on the basis of a year of three hundred
sixty (360) days. Each installment shall include all interest accrued through
the due date.


PREPAYMENTS. After one (1) year from the date Secured Party funds this Loan, 
the outstanding principal balance of the Loan may be prepaid in whole or in 
part at any time, together with all interest and late charges accrued through 
the date of prepayment and a prepayment charge calculated as follows: one 
percent (1%) of the amount prepaid multiplied by the number of years or 
fraction thereof remaining under the term of this Agreement. Partial 
prepayments shall be applied against principal installments in their inverse 
order of maturity. Except as provided herein, the Loan may not be prepaid.

LATE CHARGES. To the extent permitted by applicable law, Debtor shall pay on
demand, as a late charge, an amount equal to five percent (5%) of each
installment or part thereof that is not paid within ten (10) days of the date
when due, but nothing in this paragraph alters the definitions of events of
default hereunder. Debtor shall pay the late charge, to the extent permitted by
applicable law, regardless of whether or not Debtor's failure to pay such
installment when due is or becomes a default hereunder and regardless of whether
or not Secured Party proceeds under the "Remedies" provisions hereof or takes
any other action, and demand for and collection of the late charge shall not be
deemed a waiver of default or of any other remedies or rights.

SECURITY INTEREST. Debtor hereby grants to Secured Party a security interest in
and security title to the personal property described above as the "Equipment",
together with all parts, additions, accessions, accessories, replacements and
substitutions thereto or therefor, and all proceeds therefrom (including any
proceeds of insurance against fire or other casualty whether or not the
insurance policy contains an endorsement in favor of Secured Party), all of
which is hereinafter called the "Collateral". This security interest is given to
secure payment to Secured Party of all present and future obligations of Debtor
to Secured Party, including without limitation the obligation of Debtor to repay
the Loan and all other liabilities arising under or in connection with this
Agreement; all future advances, if any, made by Secured Party to Debtor, whether
or not made pursuant to any commitment of Secured Party (and nothing in this

                                     Page 1 of 5


<PAGE>

Agreement shall be construed to create or imply the existence of any such 
commitment); and all other liabilities of Debtor to Secured Party now 
existing or hereafter incurred, matured or unmatured, direct or contingent, 
whether or not evidenced by a promissory note, and whether owing originally 
to Secured Party or acquired by Secured Party from any other party, and any 
renewals and extension thereof and substitutions therefor. (All of the above 
obligations, including but not limited to obligations in respect of the Loan, 
are hereinafter called the "Indebtedness.") The foregoing notwithstanding, 
however, Secured Party's security interest in the Collateral shall be 
released upon payment, fully and finally, of all scheduled payments hereunder 
as and when the same become due and payable, but not by reason of prepayment 
thereof, unless all liabilities and obligations of Debtor to Secured Party 
have been paid finally and in full.

DEBTOR WARRANTS AND REPRESENTS THAT:

GOOD STANDING. Debtor is organized and existing in good standing under the laws
of the jurisdiction of its formation, has the power to own its property and to
carry on its business as now being conducted, and is duly qualified to do
business and is in good standing in each jurisdiction in which the character of
the property owned by it therein or the transaction of its business makes such
qualification necessary.

AUTHORITY. Debtor has full power and authority to enter into this Agreement, to
make the borrowing hereunder, and to incur the obligations provided for herein,
all of which have been duly authorized by all proper and necessary action. No
consent or approval of stockholders, partners, members or co-owners or of any
public authority is required as a condition to the validity of this Agreement.

BINDING AGREEMENT. This Agreement constitutes the valid and legally binding
obligation of Debtor enforceable in accordance with its terms.

LITIGATION. There are no proceedings pending or threatened before any court or
administrative agency that might materially adversely affect the financial
condition or operation of Debtor.

NO CONFLICTING AGREEMENTS. There is no charter, by-law, preference stock or
partnership agreement provision of Debtor and no provision of any other
organizational documents or existing mortgage, indenture, contract or agreement
binding on Debtor or affecting its property which would conflict with or in any
way prevent the execution, delivery or performance of the terms of this
Agreement.

OWNERSHIP FREE OF ENCUMBRANCES. Except for the security interest granted hereby,
Debtor now owns, or will use the proceeds hereof to become the owner of, the
Collateral free from any prior lien, security interest or encumbrance. No
financing statement covering the Collateral or any proceeds thereof is on file
in any public office, except for financing statements showing Secured Party as
the sole secured party thereunder. Debtor has a good right to grant a security
interest in the Collateral to Secured Party.

FIXTURES. None of the Collateral is now a part of or affixed to any real
property.

COLLATERAL LOCATION. Except for items of Collateral that constitute mobile goods
and that are in fact in use by Debtor in the ordinary course of its business at
other locations, all the Collateral comprising goods heretofore delivered to the
Debtor by the seller thereof is located either at (i) Debtor's address set forth
above or (ii) the "Equipment Location" set forth above.

DEBTOR COVENANTS AND AGREES THAT UNTIL ALL THE INDEBTEDNESS IS FULLY SATISFIED:

INSURANCE. Debtor shall maintain continuously, and pay when due all premiums
for, fire and casualty insurance with extended coverage on the Collateral,
insuring the same against loss by fire, explosion, theft and such other
casualties as are usually insured against by companies engaged in the same or
similar businesses with a responsible company or companies satisfactory to
Secured Party, in an amount not less than the unpaid balance of the Loan.
Each of such insurance policies shall have attached thereto a standard loss
payable endorsement, without contribution, in favor of Secured Party as its
interest may appear; shall provide that it may not be canceled without (30)
days' prior written notice to Secured Party; shall provide that, in respect of
Secured Party's interest in such policy, the insurance shall not be invalidated
by any action or inaction of Debtor or any other person (other than Secured
Party); shall insure Secured Party's interest in the Collateral as it may
appear, regardless of any breach or violation of any warranty, declaration or
condition contained in such policy by Debtor or any other person (other than
Secured Party); and shall otherwise be in form and substance acceptable to
Secured Party. Debtor shall deliver forthwith to Secured Party each such policy
(together with the loss payable endorsement), or certificates of insurance or
other evidence satisfactory to Secured Party of the existence of all required
insurance, its terms and conditions, and the payment of all applicable premiums.
Similar evidence of renewal coverage, satisfactory to Secured Party, shall be
delivered to Secured Party at least fifteen (15) days before the expiration of
any initial insurance coverage. In addition, Debtor shall maintain, and pay when
due all premiums for, liability and other insurance in such amounts and against
such risks as is customarily carried by persons in similar businesses owning
similar property. Debtor irrevocably appoints Secured Party as Debtor's
attorney-in-fact, with full power of substitution, during the existence of any
default under this Agreement, to execute loss claims and other applications for
payment of benefits under any insurance policy in the name of Debtor or Secured
Party, to receive all monies and to endorse drafts, checks and other instruments
for the payment of any proceeds of any insurance. This appointment shall be
deemed a power coupled with an interest and shall not be terminable by Debtor so
long as Debtor remains indebted to Secured Party.

MAINTENANCE AND CLEAR TITLE. Debtor shall keep the Collateral in good condition
and free from liens and security interests, shall not sign or suffer to be filed
any financing statements relating to the Collateral except those showing Secured
Party as sole secured party shall not sell or lease or offer to sell or lease or
otherwise encumber or dispose of any of the Collateral, shall defend the
Collateral against all claims and demands of all persons at any time claiming
any interest or right therein, and shall not use the Collateral illegally.
Secured Party may examine and inspect the Collateral at any time, wherever
located.

CHANGE OF NAME, RESIDENCE OR PLACE OF BUSINESS. Debtor shall not change its
name, residence or place of business or do business under any assumed or
fictitious name without giving Secured Party at least thirty (30) days prior
written notice.

CHANGE OF STRUCTURE. Debtor shall maintain its existence, and shall not be
prohibited from merging or consolidating with or into any other entity or sell
substantially all of its assets as long as Debtor is the surviving entity.

USE OF COLLATERAL. Debtor shall use the Collateral exclusively for business
operations.

FIXTURES. Debtor shall not permit any of the Collateral to become a part of or
affixed to any real property.

                                     Page 2 of 5

<PAGE>

LOCATION OF COLLATERAL. Except for items of Collateral that constitute mobile
goods and that are in fact in use by Debtor in the ordinary course of business
at other locations, all the Collateral shall, from and after the moment that
Debtor acquires possession or control of it, be kept either at (i) Debtor's
address set forth above or (ii) the "Equipment Location" set forth above, and
all records relating to the Collateral shall likewise be kept only at such
location or locations. If at any time the Collateral, or any part thereof, is
removed to a new location, Debtor: (a) shall provide written notice thereof to
Secured Party within thirty (30) days from the date of such relocation; and (b)
either (i) the premises in which such Collateral will be installed will be owned
by Debtor free of any liens or encumbrances, or (ii) if not owned by Debtor free
of liens or encumbrances, the owner of such premises and/or the holder of any
such liens or encumbrances on such premises shall have consented and acknowledge
the superiority of Secured Party's interest in such Collateral.

INDEMNIFICATION. Debtor shall indemnify Secured Party against all claims arising
out of or connected with the ownership or use of the Collateral.

MOTOR VEHICLES. If the Collateral consists of or includes motor vehicles or
other equipment for which there is a certificate of title evidencing ownership
thereof, Debtor shall forthwith cause each certificate to be endorsed over and
the lien of Secured Party to be noted so as to show Secured Party's interest,
and Debtor shall deliver forthwith each such certificate to Secured Party.

TAXES. Debtor shall pay promptly when due all taxes, charges and assessments
that are or may become a lien on the Collateral or any part thereof, except to
the extent that the same are contested in good faith and by appropriate
proceedings.

FINANCIAL STATEMENTS. During the term of this Loan, Debtor (i) shall furnish
Secured Party annual balance sheets and profit and loss statements of Debtor and
of any guarantor of Debtor's obligations hereunder within 120 days after the end
of Debtor's (and any guarantor's) fiscal year, and (ii) at Secured Party's
request, shall furnish Secured Party all other financial information and reports
reasonably requested by Secured Party at any time, including quarterly or other
interim balance sheets and profit and loss statement of Debtor and of any such
guarantor. Debtor shall furnish such other information as Secured Party may
reasonably request at any time concerning the Debtor and its affairs, including
without limitation information concerning the Collateral. Debtor represents and
warrants that all information furnished and to be furnished by Debtor to Secured
Party is accurate and that all financial statements Debtor has furnished and
hereafter may furnish to Secured Party, including operating statement and
statements of condition, are and will be prepared in accordance with generally
accepted accounting principals, consistently applied, and reasonably reflect and
will reflect, as of their respective dates, results of the operations and
financial condition of Debtor and of any other entity they purport to cover.

REIMBURSEMENT FOR EXPENSES.  At its option, and with no obligation to do so,
Secured Party may (i) if an event of default exists, discharge taxes or other
encumbrances on the Collateral, or pay for the repair, maintenance and
preservation of the Collateral and (ii) ten (10) days after notifying Debtor of
Secured Party's intent to do so, arrange and pay for insurance on the
Collateral.  Debtor agrees to reimburse Secured Party on demand for any payments
so made; Debtor also agrees to reimburse and pay to Secured Party on demand all
expenses incurred or paid by Secured Party in perfecting the security interest
granted hereunder and in collecting the Indebtedness and in protecting or
enforcing Secured Party's rights under this Agreement, including but not limited
to reasonable attorney's fees and legal expenses.  Until Debtor makes such
reimbursement, the amount of all such payments and expenses, with interest at
the rate then applicable to principal installments of the Loan not paid when
due, from the date of Payment until reimbursement, shall be added to the
Indebtedness and shall be secured by the security interest granted by Debtor
under this Agreement.  Nothing in this paragraph relieves Debtor of the duty to
care for, insure and protect the Collateral and Secured Party's interests
therein and to pay tax on or related to the Collateral, or of any other duty.

SALE OR REPLACEMENT OF COLLATERAL.  Debtor shall not sell or replace any item or
part of the Collateral without the prior written consent of Secured Party.

POST DEFAULT INTEREST.  Any principal balance not paid when due (whether by
acceleration or otherwise) shall accrue interest at the "Default Rate" until
such principal balance is paid. "Default Rate" shall be a per annum rate of
interest equal to (i) fifteen percent (15.0%) or (ii), if less, the highest rate
of interest permitted by applicable law.  Secured Party may, at its option,
apply late payments (either in full or partial) in the following  manner; first
to interest, then to principal, and finally to late charges.  To the extent
permitted by applicable law, Debtor shall pay interest on delinquent principal
installments on demand regardless of whether or not Secured Party proceeds under
the "Remedies" provisions hereof or takes any other action, and demand for and
collection of interest on such overdue installments at the Default Rate shall
not be deemed a waiver of default or of any other remedies or rights.

EVENTS OF DEFAULT.  Debtor shall be in default under this Agreement upon the
happening of any of the following events or conditions, each of which is an
event of default:

     1.   Default shall be made in the payment of any installment of the Loan,
or in the payment of any other Indebtedness, when and as the same become due and
payable, whether at the stated maturity thereof or by acceleration or otherwise,
and such default shall continue unremedied for ten (10) days; or

     2.   Default shall be made in the due observance or performance of any
term, covenant or agreement contained in this Agreement (other than covenants
and agreements to pay Indebtedness), and such default shall continue unremedied
for ten (10) days after written notice thereof is given by Secured Party to
Debtor; or

     3.   Any representation or warranty made by Debtor in this Agreement, or
any statement or representation made in any certificate, report or opinion
delivered pursuant hereto, or in connection herewith, shall prove to have been
incorrect in any material respect when made; or

     4.   A default exists under any other agreement or instrument of Debtor's
with or in favor of Secured Party; or

     5.   The Collateral shall be lost, stolen, substantially damaged, destroyed
(unless (i) such occurrence is fully covered by insurance, and (ii) the Loan is
fully repaid within thirty (30) days after such occurrence), or shall be sold or
encumbered; or Debtor's rights in the Collateral shall be voluntarily or
involuntarily transferred, by way of sale, lease or creation of a security
interest, or by way of attachment, levy, garnishment or other judicial process,
or otherwise; or


                                     Page 3 of 5
<PAGE>


     6.   Debtor shall become insolvent or be generally unable to meet its
obligations as they mature, make an assignment for the benefit of creditors,
admit in writing its inability to pay its debts as they mature, or suspend the
operation of its present business; or

     7.   A trustee, receiver or custodian shall be appointed for Debtor or for
a substantial part of its property without the consent of Debtor and not be
discharged within thirty (30) days; or

     8.   Bankruptcy, reorganization, arrangement, insolvency or liquidation
proceedings shall be instituted by or against Debtor, and, if instituted against
Debtor, be consented to or remain undismissed for a period of thirty (30) days;
or

     9.   An event described in Section 6, 7, or 8 shall occur with respect to
any party who is guarantor or surety for the Indebtedness; or

     10.  The Borrower shall fail to pay when due (whether at final maturity or
as a result of acceleration) principal or interest payments then due under the
terms of any bonds, notes debentures or other agreements evidencing, in the
aggregate, at least $2,000,000 of Debt (excluding, for purposes of this
calculation, payments required under this Agreement or any of the other Loan
Documents) and such non-payment shall continue beyond any period of grace
provided with respect thereto, or the Borrower shall default in the observance
or performance of any other agreement contained in any such bonds, notes,
debentures or other agreements evidencing indebtedness, and the effect of such
failure or default is to cause the indebtedness evidenced thereby to be
accelerated by the holders thereof prior to its stated date of maturity; or

     11.  Liquidation or dissolution of Debtor; or

     12.  Sale, transfer or exchange, directly or indirectly, in one or more
transactions, of a controlling stock interest in Debtor or the suspension of
Debtor's present business; or

     13.  The Pension Benefit Guaranty Corporation shall commence proceedings
under Section 4042 of the Employee Retirement Income Security Act of 1974 to
terminate any employee pension benefit plan of Debtor; or

     14.  The attempted repudiation of any guaranties for obligations of Debtor
to Secured Party.

REMEDIES.  Upon any event of default and at any time thereafter, Secured 
Party may declare all the Indebtedness immediately due and payable in full 
(unless such event of default comprises one or more of the events described 
in paragraphs 7 or 8 above, in which case all the Indebtedness shall become 
immediately due and payable in full without declaration, notice or other 
action on the part of Secured Party), and may proceed to enforce payment 
thereof and exercise any and all of the rights and remedies provided by the 
Uniform Commercial Code as well as all other rights and remedies of Secured 
Party hereunder or under other applicable law.  Upon the occurrence of an 
event of default, Debtor shall, upon demand by Secured Party, assemble the 
Collateral and make it available to Secured Party at a place designated by 
Secured Party reasonably convenient to both parties.  Secured Party may, at 
its election, enforce its rights under this Agreement by a suit in equity for 
specific performance.  Debtor grants Secured Party the right to enter upon 
premises of Debtor for the purpose of recovering possession of the Collateral 
or any part thereof after the occurrence of an event of default, or for the 
preservation or enforcement of Secured Party's other rights hereunder, all 
without demand or notice to Debtor and without judicial hearing or 
proceedings, which Debtor hereby expressly waives.  The requirements of 
reasonable notice shall be deemed met if such notice is mailed to an address 
of Debtor shown at the beginning of this Agreement at least ten (10) days 
before the time of the sale or disposition, but nothing contained herein 
shall be construed to mean that other notice or a shorter period of time does 
not constitute reasonable notice of the sale or other disposition of the 
Collateral.  Debtor shall reimburse Secured Party for all Secured Party's 
expenses of retaking, holding, preparing for sale, selling or otherwise 
dealing with disposing of the Collateral, including attorney's fees in the 
amount of fifteen percent (15%) of the outstanding principal balance of and 
interest on the Indebtedness (but not to exceed the amount of attorney's fees 
actually incurred) if collection is by or through an attorney at law.  
Subject to applicable law, Debtor shall pay any Indebtedness remaining unpaid 
after sale or other disposition of any or all of the Collateral.  Any surplus 
proceeds from the sale or other disposition of the Collateral remaining after 
full satisfaction of the Indebtedness shall be paid to Debtor or to such 
other persons as may be entitled thereto under applicable law.

CUMULATIVE RIGHTS AND NO WAIVER.  Each and every right granted Secured Party 
hereunder or in connection herewith, or allowed it by law or equity, shall be 
cumulative and may be exercised from time to time.  No failure on the part of 
Secured Party to exercise, and no delay in exercising, any right shall 
operate as a waiver thereof, nor shall any single or partial exercise by 
Secured Party of any right preclude any other or future exercise thereof or 
the exercise of any other right.

FINANCING STATEMENTS.  Debtor shall sign and deliver to Secured Party such
financing statements and other documents as Secured Party may deem necessary to
perfect, protect and continue its security interest in the Collateral, in form

                                 AMENDMENT OF LEASE

          This Amendment of Lease (this "Agreement"), dated as of the 30th 
day of September, 1997, between HUDSON TELEGRAPH ASSOCIATES, a New York 
limited partnership, having an address c/o Williams Real Estate Co. Inc., 530 
Fifth Avenue, New York, New York 10036 ("Landlord") and STAR 
TELECOMMUNICATIONS, INC., a Delaware corporation, having an address at 740 
State Street, Santa Barbara, CA 93101.

                                    WITNESSETH:

          WHEREAS:

          A.   Landlord and Star Vending, Inc., as Tenant was formerly known, 
entered into a lease dated as of February 28, 1996 (the "Original Lease"), as 
amended by amendment dated as of October 14, 1996 (the Original Lease, as so 
amended, being referred to herein as the "Existing Lease") pursuant to which 
Tenant leased portions of the 12th floor (the "Existing Premises") in the 
building known as 60 Hudson Street, New York, New York (the "Building") for a 
Term which is presently scheduled to expire on April 30, 2006.

          B.   On February 26, 1997, Star Vending, Inc. reincorporated in the 
State of Delaware under the name Star Telecommunications, Inc. and 
subsequently conducted an initial public offering of its common capital stock 
(the "Offering").

          C.   Landlord and Tenant wish to increase the premises demised 
under the Existing Lease by adding thereto the premises, located on the 13th 
floor of the Building, shown hatched on Exhibit A annexed hereto (the "New 
Premises"), to extend the Term of the Existing Lease, and to make certain 
other changes in the Existing Lease.

          NOW, THEREFORE, in consideration of the foregoing and the mutual 
covenants hereinafter contained, Landlord and Tenant agree that the Existing 
Lease is hereby amended as follows:

          1.   All terms contained in this Agreement shall, for the purposes 
hereof, have the same meanings ascribed to them in the Original Lease unless 
otherwise defined herein.  As used herein, the term "Lease" shall mean the 
Existing Lease as amended by this Agreement and as the same may be hereafter 
amended.

          2.   Effective as of the "New Premises Date," as hereinafter 
defined, the "premises" or "demised premises" shall be the Existing Premises 
plus the New Premises.   The New Premises Date is the date on which Landlord 
delivers possession of the New


<PAGE>

Premises to Tenant with all items of Landlord's Work (as hereinafter 
defined), except the submeter installation and the window pane replacement, 
substantially complete.

          3.   The Term of the Lease with respect to the entire demised premises
is extended to April 30, 2008.


          4.   Commencing on the New Premises Date, the annual Fixed Rent 
payable under the Lease shall be increased to $578,179 per annum.  On May 1, 
2001, the annual Fixed Rent payable under the Lease shall be increased to 
$600,277 per annum; on May 1, 2002, the annual Fixed Rent payable under the 
Lease shall be increased to $630,377 per annum; and on May 1, 2006, the Fixed 
Rent payable under the Lease shall be increased to $652,475 per annum. 
Notwithstanding anything to the contrary contained herein, provided the Lease 
is in full force and effect and Tenant is not in default thereunder beyond 
any applicable notice and/or cure period, the Fixed Rent payable under the 
Lease, as hereby increased, shall abate by $28,845.83 per month from the New 
Premises Date to but not including the later to occur of May 1, 1998 or the 
date that is seven (7) months after the New Premises Date (such later date 
being the "Rent Commencement Date"), as the same may be extended pursuant to 
Paragraph 5(c) hereof.

          5.   (a)  Landlord will, with reasonable diligence after the 
execution and exchange of this Agreement, perform the Landlord's Work, all at 
Landlord's expense except for the submeter and the installation thereof, 
which will be at Tenant's expense.  Upon substantial completion of such work 
(except the submeter installation and the window pane replacement), Landlord 
shall deliver to Tenant, and Tenant shall accept, the demised premises in 
their then "as is" broom-clean condition.  Tenant acknowledges that Landlord 
shall not be required to perform any work to prepare the demised premises for 
Tenant's occupancy except for the Landlord's Work. The taking of possession 
of the demised premises by Tenant shall be conclusive evidence as against 
Tenant that, at the time such possession was so taken, the demised premises 
and the Building were in good and satisfactory condition and the Landlord's 
Work was substantially complete, except for the submeter installation, the 
window pane replacement and any punchlist items of which Tenant notifies 
Landlord within thirty (30) days after the New Premises Date. Landlord will 
install the submeter, replace the broken window panes and complete the 
punchlist items with reasonable diligence after the New Premises Date (but 
Landlord shall not be required to use overtime labor or incur other 
additional expense to do so), and, in the case of the window pane 
replacement, not later than the date on which Tenant's work is completed.

               (b)  The "Landlord's Work" consists of the following:

                                        -2-

<PAGE>

                         (1)  Complete demolition of the existing improvements
in the premises, except for floor tile;

                         (2)  installation of a submeter at Tenant's expense,
which expense shall be reimbursed to Landlord within fifteen (15) days after
Landlord bills Tenant therefor;

                         (3)  construction of a Building standard demising 
wall and entrance door; and

                         (4)  replacement of broken window panes.

               (c)  If the New Premises Date has not occurred by October 15, 
1997 for any reason other than force majeure or other events beyond 
Landlord's reasonable control, the Rent Commencement Date shall be delayed by 
one day for each day of delay, beyond October 15, 1997, in the occurrence of 
the New Premises Date.  (Thus, for example, if the New Premises Date were 
delayed until October 18, 1997 by reason of events other than force majeure 
or events beyond Landlord's reasonable control, the Rent Commencement Date 
would be May 21, 1998.)  In addition, if the New Premises Date has not 
occurred by January 1, 1998 for whatever reason, Tenant shall have the right, 
to be exercised by notice to Landlord given no later than January 15, 1998, 
as to which date time shall be of the essence, but in any event not after the 
occurrence of the New Premises Date, to cancel this Agreement ab initio, in 
which event the Existing Lease shall continue as if this Agreement had never 
been made and Landlord will return to Tenant any amounts paid to Landlord 
hereunder (to the extent allocable to the New Premises).

     6.   If any friable asbestos (not including asbestos floor tile, as to 
which Landlord shall have no responsibility) is discovered in the New 
Premises that is not the responsibility of Tenant as provided in the Lease 
and is required by applicable Law to be removed or encapsulated, then, as 
Tenant's sole remedy, Landlord will at Landlord's expense and with reasonable 
promptness remove or encapsulate such asbestos in accordance with Law.  
Landlord will deliver to Tenant with reasonable promptness after the New 
Premises Date a Form ACP-5 for the premises.

     7.   It is the intention of the parties that additional rent payable by 
Tenant pursuant to the Lease be calculated separately for the Existing 
Premises and the New Premises, with the calculations for the Existing 
Premises being made pursuant to the provisions of Articles 37, 39 and 40 of 
the Existing Lease as unmodified by this Agreement and the calculations for 
the New Premises being made pursuant to the provisions of Articles 37, 39 and 
40 of the Existing Lease with the following modifications:

          (a)  "Base Tax Year" for the New Premises shall mean the tax fiscal 
year July 1, 1997 - June 30, 1998.

                                        -3-

<PAGE>

               (b)  "Base Year Taxes" for the New Premises shall mean the Real
Estate Taxes as finally determined for the Base Tax Year for the New Premises.

               (c)  "Subsequent Tax Year" for the New Premises shall mean any
tax fiscal year commencing on or after July 1, 1998.

               (d)  "Tenant's Proportionate Share" for the New Premises shall
mean 1.79%.

               (e)  "Base Operating Year" for the New Premises shall mean the
Operating Expenses incurred for 1997.

               (f)  "Operational Year" for the New Premises shall mean each
calendar year all or any part of which occurs during the Term commencing with
1998.

          8.   Effective as of the New Premises Date, Landlord shall furnish, 
for Tenant's use in the New Premises, fifteen (15) watts per rentable square 
foot of electric current at 120/208 volts, three phase, at a panel box in the 
New Premises, upon and subject to the terms and conditions provided in 
Article 42 of the Lease.  If at any time during the Term, whether before or 
after Tenant's power for the New Premises is increased or decreased, Landlord 
reasonably determines that Tenant is not using any portion of the electric 
capacity then servicing the New Premises, then Landlord shall have the right 
to recapture any such power not then being used by Tenant without 
compensation to Tenant.  (If, with respect to the New Premises, Landlord 
recaptures a portion of Tenant's original fifteen (15) watts per rentable 
square foot, and at a later date Landlord provides Tenant with additional 
current, Tenant shall only be required to pay the per amp charge set forth in 
the Original Lease for total current in excess of fifteen (15) watts per 
rentable square foot.  As set forth in the Existing Lease, if, with respect 
to the Existing Premises, Landlord recaptures a portion of Tenant's original 
ten (10) watts per rentable square foot, and at a later date Landlord 
provides Tenant with additional current, Tenant shall only be required to pay 
the per amp charge set forth in the Original Lease for total current in 
excess of ten (10) watts per rentable square foot.)  Tenant's consumption of 
energy in the New Premises will be measured by one or more submeters to be 
installed by Landlord at Tenant's expense.  Anything in the Lease to the 
contrary notwithstanding, if the New Premises Date occurs prior to the 
installation and proper calibration of the submeter(s), then (i) Tenant shall 
pay Landlord for Tenant's consumption of electricity in the New Premises at 
the rate of $1,881.25 per month during any period when construction is taking 
place in the New Premises; and (ii) from and after the date on which Tenant 
occupies all or a portion of the demised premises for the conduct of business 
and until the installation and proper calibration of the submeter(s), Tenant 
shall pay Landlord $3,762.50 per month on

                                         -4-

<PAGE>

account, such payments to be retroactively adjusted based on the average
kilowatts and kilowatt hours consumed over the first three (3) months after
installation and proper calibration of the submeter(s).

          9.   Simultaneously with the execution of this Agreement, Tenant has
delivered to Landlord a check subject to collection in the amount of $86,537.00,
increasing the amount of the Security Deposit to $172,935.00.  Provided that
Tenant is not then in default, Tenant will be permitted to reduce the amount of
the Security Deposit by $57,691.00 on the third (3rd) anniversary of the Rent
Commencement Date.  If the Security Deposit is in cash, Landlord will pay to
Tenant the amount of any applicable reduction within fifteen (15) business days
after Tenant's request therefor accompanied by the required certification.  If
the Security Deposit is a Letter of Credit, Landlord will accept a Letter of
Credit in the proper reduced amount in exchange for the existing Letter of
Credit, or will enter into an amendment of the Letter of Credit reducing the
amount thereof to the proper reduced amount.

          10.  The covenants, agreements, terms and conditions contained in this
Agreement shall bind and inure to the benefit of the parties hereto and their
respective successors, and, except as otherwise provided in the Lease, their
respective assigns.

          11.  Except as amended by this Agreement, the Existing Lease and all
covenants, agreements, terms and conditions thereof shall remain in full force
and effect and the Existing Lease, as so amended, is hereby in all respects
ratified and confirmed.

          12.  Landlord and Tenant each covenants, represents and warrants to 
the other that it has had no dealings or communications with any broker or 
agent in connection with the consummation of this Agreement other than 
Williams Real Estate Co. Inc. (representing Landlord) and Cushman & 
Wakefield, Inc. (representing Tenant) (collectively, the "Broker") and each 
party covenants and agrees to indemnify the other from and against all costs, 
expenses (including reasonable attorneys' fees and disbursements) and 
liability for any commission or other compensation claimed by any broker or 
agent with whom the indemnifying party dealt (other than the Broker, whose 
commission will be paid by Landlord pursuant to a separate agreement) with 
respect to this Agreement.

          13.  Landlord acknowledges that neither the reincorporation nor the
Offering referred to in Recital B constitutes an assignment or subletting under
Articles 11 and 44 of the Lease.

          14.  Clause (iii) in the second sentence of Section 44(M) of the Lease
is amended to read as follows:


                                         -5-

<PAGE>

               "(iii) any license shall be for equipment (and the monitoring,
repair, and maintenance thereof) only and shall not grant to the licensee the
right to occupy any portion of the Building or the demised premises except to
the extent that such occupancy is necessary or appropriate for such monitoring,
repair, and/or maintenance."

          15.  This Agreement may not be changed orally, but only by a writing
signed by the party against whom enforcement thereof is sought.

          IN WITNESS WHEREOF, the parties hereto have executed this Agreement as
of the day and year first above written.

                                   LEASE AGREEMENT

     This LEASE AGREEMENT, is effective on July 29, 1996 between
TELECOMMUNICATIONS FINANCE GROUP (hereinafter "Lessor"), and STAR VENDING, INC.,
a California corporation with its principal office located at 740 State Street,
Suite 202, Santa Barbara, CA  93101, (hereinafter "Lessee").

1.   LEASE.

     Lessor, subject to the conditions set forth in Section 25 hereof, agrees 
to lease to Lessee and Lessee agrees to lease from Lessor hereunder, those 
items of personal property (the "equipment") which are described on Schedule 
1 of Exhibit A hereto and amendments to Schedule 1.  Lessee agrees to execute 
and deliver to Lessor a certificate of delivery and acceptance in 
substantively the form of Exhibit A hereto (a "Delivery Certificate") 
immediately after Turnover of the equipment, and such execution shall 
constitute Lessee's irrevocable acceptance of such items of equipment for all 
purposes of this Lease.  The Delivery Certificate shall constitute a part of 
this Lease to the same extent as if the provisions thereof were set forth 
herein.

2.   DEFINITIONS.

     "AMORTIZATION DEDUCTIONS" as defined in Section 11(b)(i) hereof.

     "APPRAISAL PROCEDURE" shall mean the following procedure for determining
     the Fair Market Sale Value of any item of equipment.  If either Lessor or
     Lessee shall request by notice (the "Appraisal Request") to the other that
     such value be determined by the Appraisal Procedure, (i) Lessor and Lessee
     shall, within 15 days after the Appraisal Request, appoint an independent
     appraiser mutually satisfactory to them, or (ii) if the parties are unable
     to agree on a mutually acceptable appraiser within such time, Lessor and
     Lessee shall each appoint one independent appraiser (PROVIDED that if
     either party hereto fails to notify the other party hereto of the identity
     of the independent appraiser chosen by it within 30 days after the
     Appraisal Request, the determination of such value shall be made by the
     independent appraiser chosen by such other party), and (iii) if such
     appraisers cannot agree on such value within 20 days after their
     appointment and if one appraisal is not within 5% of the other appraisal,
     Lessor and Lessee shall choose a third independent appraiser mutually
     satisfactory to them (or, if they fail to agree upon a third appraiser
     within 25 days after the appointment of the first two appraisers, such
     third independent appraiser shall within 20 days thereafter be appointed by
     the American Arbitration Association), and such value shall be determined
     by such third independent appraiser within 20 days after his appointment,
     after consultation with the other two independent appraisers.  If the first
     two appraisals are within 5% of each other, then the average of the two
     appraisals shall be the Fair Market Sale Value.  The fees and expenses of
     all appraisers shall be paid by Lessee.

     "BUSINESS DAY" shall mean a day other than a Saturday, Sunday or legal
     holiday under the laws of the State of Florida.

     "CODE" shall mean the Internal Revenue Code of 1954, as amended, or any
     comparable successor law.

     "COMMENCEMENT DATE" as defined in Section 3 hereof.

     "DEFAULT" shall mean any event or condition which after the giving of
     notice or lapse of time or both would become an Event of Default.

     "DELIVERY CERTIFICATE" as defined in Section 1 hereof.

     "EQUIPMENT" as defined in Section 1 hereof.

     "EVENT OF DEFAULT" as defined in Section 18 hereof.

     "EVENT OF LOSS" shall mean, with respect to any item of equipment, the
     actual or constructive total loss of such item of equipment or the use
     thereof, due to theft, destruction, damage beyond repair or rendition
     thereof permanently unfit for normal use from any reason whatsoever, or the
     condemnation, confiscation or seizure of, or requisition of title to or use
     of such item of equipment.

     "FAIR MARKET SALE VALUE" shall, at any time with respect to any item of
     equipment, be equal to the sale value of such item of equipment which would
     be obtained in an arm's-length transaction between an informed and willing
     seller under no compulsion to sell and an informed and willing buyer-user
     (other than a lessee currently in possession or a used equipment or scrap
     dealer).  For purposes of Section 7(b) hereof, Fair Market Sale Value
     shall be determined by (i) an independent appraiser (at Lessee's expense)
     selected by Lessor or (ii) by the Appraisal Procedure if the Appraisal
     Request is made at least 90 days (but not more than 360 days) prior to the
     termination or expiration of the Lease Term, as the case may be, which
     determination shall be made (a) without deduction for any costs or expenses
     of dismantling or removal; and (b) on the assumption that such item of
     equipment is free and clear of all Liens and is in the condition and repair
     in which it is required to be returned pursuant to Section 7(a) hereof.
     For purposes of Section 19(c) hereof, Fair Market Sale Value shall be
     determined (at Lessee's expense) by an independent appraiser selected by
     Lessor, on an "as-is, where-is" basis, without regard to the provisions of
     clauses (a) and (b) above; PROVIDED that if Lessor shall have sold any item
     of equipment pursuant to Section 19(b) hereof prior to giving the notice
     referred to in Section 19(c) hereof, Fair Market Sale Value of such item of
     equipment shall be the net proceeds of such sale after deduction of all
     costs and expenses incurred by Lessor in connection therewith; PROVIDED
     FURTHER, that if for any reason Lessor is not able to obtain possession of
     any item of equipment pursuant to Section 19(a) hereof, the Fair Market
     Sale Value of such item of equipment shall be zero.

     "IMPOSITION" as defined in Section 11(a) hereof.

5.   RENT; UNCONDITIONAL OBLIGATIONS.

     (a)  Lessee agrees to pay to Lessor, at the address specified in Section 
24 hereof or at such other address as Lessor may specify, rent for the 
initial equipment at a rate not to exceed $21,993 per $1,000 of the total 
Lessor's Value of such items of equipment, as set forth in Schedule 1 of 
Exhibit A dated July 29, 1996, (plus applicable sales or use taxes) per 
month, in sixty (60) consecutive monthly installments, with the first 
installment of rent being due on the Commencement Date unless the 
Commencement Date is other than the first day of a calendar month, in which 
event the first installment of rent shall be due on the first day of the 
month following the Commencement Date, and succeeding installments being due 
on the same date of each month thereafter.  In the event of any additions to 
the initially leased equipment, the rental rate on any additional equipment

the equipment to the lease.

     (b)  Lessee shall also pay to Lessor, on demand, interest at the late
Charge Rate on any installment of rent and on any other amount owing hereunder
which is not paid on its due date, for any period for which the same shall be
overdue.  Each payment made under this Lease shall be applied first to the
payment of interest then owing and then to rent or other amounts owing
hereunder.  Interest shall be computed on the basis of a 360-day year and actual
days elapsed.

     (c)  This Lease is a net lease, and Lessee's obligation to pay all rent 
and all other amounts payable hereunder is ABSOLUTE AND UNCONDITIONAL under 
any and all circumstances and shall not be affected by any circumstances of 
any character whatsoever, including, without limitation, (i) any set-off, 
counterclaim, recoupment, defense, abatement or reduction or any right which 
Lessee may have against Lessor, the manufacturer or supplier of any of the 
equipment or anyone else for any reason whatsoever; (ii) any defect in the 
title, condition, design, or operation of, or lack of fitness for use of, or 
any damage to, or loss of, all or any part of the equipment from any cause 
whatsoever; (iii) the existence of any Liens with respect to the equipment; 
(iv) the invalidity, unenforceability or disaffirmance of this Lease or any 
other document related hereto; or (v) the prohibition of or interference with 
the use or possession by Lessee of all or any part of the equipment, for any 
reason whatsoever, including without limitation, by reason of (1) claims for 
patent, trademark or copyright infringement; (2) present or future 
governmental laws, rules or orders; (3) the insolvency, bankruptcy or 
reorganization of any person; and (4) any other cause whether similar or 
dissimilar to the foregoing, any present or future law to the contrary 
notwithstanding.  Lessee hereby waives, to the extent permitted by applicable 
law, any and all rights which it may now have or which may at any time 
hereafter be conferred upon it, by statute or otherwise, to terminate, 
cancel, quit or surrender the lease of any equipment.  If for any reason 
whatsoever this Lease or any Supplement, other than pursuant to Section 16(b) 
hereof, shall be terminated in whole or in part by operation of law or 
otherwise, Lessee will nonetheless pay to Lessor an amount equal to each 
installment of rent at the time such installment would have become due and 
payable in accordance with the terms hereof.  Each payment of rent or other 
amount paid by Lessee hereunder shall be final and Lessee will not seek to 
recover all or any part of such payment for Lessor for any reason whatsoever.

FOREGOING RIGHTS SHALL AUTOMATICALLY REVERT TO LESSOR UPON THE OCCURRENCE AND
DURING THE CONTINUANCE OF ANY EVENT OF DEFAULT HEREUNDER, OR UPON THE RETURN OF

7.   DISPOSITION OF EQUIPMENT.

     (a)  RETURN.

     Lessee shall, upon the expiration or earlier termination of the Lease Term
of each item of equipment, subject to paragraph (b) below, return such item of
equipment to Lessor at such place within the continental United States of
America as Lessor shall designate in writing to Lessee.  Until such item of
equipment is returned to Lessor pursuant to the provisions of this Section, all
of the provisions of this Lease with respect thereto shall continue in full
force and effect. Lessee shall pay all the costs and expenses in connection with
or incidental to the return of the equipment, including, without limitation, the
cost of removing, assembling, packing, insuring and transporting the equipment.
At the time of such return, the equipment shall be in the condition and repair
required to be maintained by Section 12 hereof and free and clear of all Liens.

     (b)  PURCHASE OPTION.

     So long as no Default or Event of Default shall have occurred and be
continuing, Lessee may, by written notice given to Lessor at least 120 days (but
not more than 360 days) prior to the expiration date of the Lease Term of any
item of equipment (which notice shall be irrevocable), elect to purchase such
item of equipment on such expiration date for a cash purchase price equal to the
Fair Market Sale Value of such item of equipment determined as of such
expiration date, plus an amount equal to all taxes (other than income taxes on
any gain on such sale), costs and expenses (including legal fees and expenses)
incurred or paid by Lessor in connection with such sale.  Upon payment by Lessee
of such purchase price, and of all other amounts then due and payable by Lessee,
Lessor shall transfer title, if any, to such items of equipment except computer
software to Lessee on an "as-is, where-is" basis, without recourse and without
representation or warranty of any kind, express or implied, other than a

business or operations of Lessee.

     (g)  UNITED STATES SOURCE INCOME.

(2) of the Code;

12.   COMPLIANCE WITH LAWS; OPERATION AND MAINTENANCE.

     (a)  Lessee will use the equipment in a careful and proper manner, will
comply with and conform to all governmental laws, rules, and regulations
relating thereto, and will cause the equipment to be operated in accordance with
the manufacturer's or supplier's instructions or manuals.

     (b)  Lessee will, at its own expense, keep and maintain the equipment in 
good repair, condition and working order and furnish all parts, replacements, 
mechanisms, devices and servicing required therefor so that the value, 
condition and operating efficiency therefor will at all times be maintained 
and preserved, reasonable wear and tear excepted. Lessee will, at its own 
expense, perform all required acts necessary to maintain any manufacturer's 
warranties and guarantees respecting the equipment. All such repairs, parts, 
mechanisms, devices and replacements shall immediately, without further act, 
become the property of Lessor and part of the equipment.

     (c)  Lessee will not make or authorize any improvement, change, addition 
or alteration to the equipment (i) if such improvement, change, addition or 
alteration will impair the originally intended function or use of the 
equipment or impair the value of the equipment as it existed immediately 
prior to such improvement, change, addition or alteration; or (ii) if any 
parts installed in or attached to or otherwise becoming a part of the 
equipment as a result of any such improvement, change, addition or 
alteration shall not be readily removable without damage to the equipment. 
Any part which is added to the equipment without violating the provisions of 
the immediately preceding sentence and which is not a replacement or 
substitution for any property which was a part of the equipment, shall remain 
the property of Lessee and may be removed by Lessee at any time prior to the 
expiration or earlier termination of the Lease Term. All such parts shall be 
and remain free and clear of any Liens. Any such part which is not so removed 
prior to the expiration or earlier termination of the Lease Term shall, 
without further act, become the property of Lessor.

13.  INSPECTION.

     Upon prior notice, Lessor or its authorized representatives may at any
reasonable time or times inspect the equipment when it deems it necessary to
protect its interest therein.

14.  IDENTIFICATION.

     Lessee shall, at its expense, attach to each item of equipment a notice
satisfactory to Lessor disclosing Owner's ownership of such item of equipment.

15.  PERSONAL PROPERTY.

     Lessee represents that the equipment shall be and at all times remain
separately identifiable personal property. Lessee shall, at its expense, take
such action (including the obtaining and recording of waivers) as may be
necessary to prevent any third party from acquiring any right to or interest in
the equipment by virtue of the equipment being deemed to be real property or a
part of real property or a part of other personal property, and if at any time
any person shall claim any such right or interest, Lessee shall, at its expense,
cause such claim to be waived in writing or otherwise eliminated to Lessor's
satisfaction within 30 days after such claim shall have first become known to
Lessee.

16.  LOSS OR DAMAGE.

     (a)  All risk of loss, theft damage or destruction to the equipment or any
part thereof, however incurred or occasioned, shall be borne by Lessee and,
unless such occurrence constitutes an Event of Loss pursuant to paragraph (b) of
this Section, Lessee shall promptly give Lessor written notice hereof and shall
promptly cause the affected part or parts of the equipment to be replaced or
restored to the condition and repair required to be maintained by Section 12
hereof.

     (b)  If an Event of Loss with respect to any item of equipment shall occur,
Lessee shall promptly give Lessor written notice thereof, and Lessee shall pay
to Lessor as soon as it receives insurance proceeds with respect to said Event
of Loss but in any event no later than 90 days after the occurrence of said
Event of Loss an amount equal to the sum of (i) the Stipulated Loss Value of
such item of equipment computed as of the Rent Payment Date with respect to such
item of equipment on or immediately preceding the date of the occurrence of such
Event of Loss; and (ii) all rent and other amounts due and owing hereunder for
such item of equipment on or prior to the Loss Payment Date. Upon payment of
such amount to Lessor, the lease of such item of equipment hereunder shall
terminate, and Lessor will transfer within forty days to Lessee, Lessor's right,
title, if any, and interest in and to such item of equipment, on an "as-is,
where-is" basis, without recourse and without representation or warranty,
express or implied, other than a representation and warranty that such item of
equipment is free and clear of any Lessor's Liens.

     (c)  Any payments received at any time by Lessor or Lessee from any insurer
with respect to loss or damage to the equipment shall be applied as follows: (i)
if such payments are received with respect to an Event of Loss they shall be
paid to Lessor, but to the extent received by Lessor, they shall reduce or
discharge, as the case may be, Lessee's obligation to pay the amounts due to
Lessor under Section 16 (b) hereof with respect to such Event of Loss; or (ii)
if such payments are received with respect to any loss of or damage to the
equipment other than an Event of Loss, such payments shall, unless a Default or
Event of Default shall have occurred and be continuing, be paid over to Lessee
to reimburse Lessee for its payment of the costs and expenses incurred by Lessee
in replacing or restoring pursuant to Section 16 (a) hereof the part or parts of
the equipment which suffered such loss or damage.

from and against any and all liabilities, obligations, losses, damages,
penalties, claims, actions, suits, costs and expenses, including reasonable
legal expenses, of whatsoever kind and nature, imposed on, incurred by or

Lease or the enforcement hereof, or the manufacture, purchase, acceptance,
rejection, ownership, possession, use, selection, delivery, lease, operation,
condition, sale, return or other disposition of the equipment or any part
thereof (including, without limitation, latent or other defects, whether or not
discoverable by Lessee or any other person, any claim in tort whether or not for
strict liability and any claim for patent, trademark, copyright or other
intellectual property infringement); provided, however, that Lessee shall not be
required to indemnify any Indemnitee for loss or liability arising from acts or
events which occur after the equipment has been returned to Lessor in accordance
with the Lease, or for loss or liability resulting solely from the willful
misconduct or gross negligence of such indemnitee. The provisions of this
Section shall survive the expiration or earlier termination of this Lease.

19.       REMEDIES.

          If an Event of Default specified in Subsection 18(vii) or (viii) 
above shall occur, then, and in any such event, Lessor shall not be obligated 
to purchase or lease any of the equipment and this Lease shall, without any 
declaration or other action by Lessor, be in default. If an Event of Default, 
other than an Event of Default specified in Subsection 18(vii) or (viii) 
above, shall occur, Lessor may, at its option, declare this Lease to be in 
default. At any time after this Lease is in default under the first sentence 
of this Section 19, Lessor has declared this Lease to be in default under the 
second sentence of this Section 19, Lessor and/or its representative may do 
any one or more of the following with respect to all of the equipment or any 
part thereof as Lessor in its sole discretion shall elect, to the extent 
permitted by applicable law then in effect:

          (a) demand that Lessee, and Lessee shall at its expense upon such
demand, return the equipment promptly to Lessor at such place in the continental
United States of America as Lessor shall specify, or Lessor and/or its agents,
at its option, may with or without entry upon the premises where the equipment
is located and disable the equipment, or make the equipment inoperable
permanently or temporarily in Lessor's sole discretion, and/or take immediate
possession of the equipment and remove the same by summary proceedings or
otherwise, all without liability for or by reason of such entry or taking of
possession, whether for the restoration of damage to property caused by such
taking or for


                                         -7-

disabling or otherwise;

          (b) sell the equipment at public or private sale, with or without
notice, advertisement or publication, as Lessor may determine, or otherwise
dispose of, hold, use, operate, lease to others or keep idle the equipment as
Lessor in its sole discretion may determine, all free and clear of any rights of
Lessee and without any duty to account to Lessee with respect to such action or
inaction or for any proceeds with respect thereto;

          (c) by written notice to Lessee specifying a payment date which shall
be not earlier than 20 days after the date of such notice, demand that Lessee
pay to Lessor, and Lessee shall pay to Lessor, on the payment date specified in
such notice, as liquidated damages for loss of a bargain and not as a penalty,
all accrued and unpaid rent for the equipment due on all Rent Payment Dates up
to and including the payment date specified in such notice PLUS an amount
(together with interest on such amount at the Late Charge Rate, from the payment
date specified in such notice to the date of actual payment) equal to the
excess, if any, of the Stipulated Loss Value of the equipment as of the payment
date specified in such notice over the Fair Market Sale Value of the equipment
as of such date;

          (d) Lessor may exercise any other right or remedy which may be
available to it under applicable law or proceed by appropriate court action to
enforce the terms hereof or to recover damages for the breach hereof or to
rescind this Lease. Lessor is entitled to recover any amount that fully
compensates the Lessor for any damage to or loss of the Lessor's residual
interest in the equipment caused by the Lessee's default.

          In the event any present value discounting is applied, the discount
rate used shall be the Federal Reserve Board Discount Rate.

          In addition, Lessee shall be liable for any and all unpaid rent and
other amounts due hereunder before or during the exercise of any of the
foregoing remedies and for all reasonable legal fees and other costs and
expenses incurred by reason of the occurrence of any Event of Default or the
exercise of Lessor's remedies with respect thereto, including all reasonable
costs and expenses incurred in connection with the placing of the equipment in
the condition required by Section 12 hereof.

          No remedy referred to in this Section 19 is intended to be exclusive,
but each shall be cumulative and in addition to any other remedy referred to
herein or otherwise available to Lessor at law or in equity; and the exercise or
beginning of exercise by Lessor of any one or more of such remedies shall not
preclude the simultaneous or later exercise by Lessor of any or all such other
remedies. No express or implied waiver by Lessor of an Event of Default shall in
any way be, or be construed to be, a waiver of any future or subsequent Event of
Default. To the extent permitted by applicable law, Lessee hereby waives any
rights now or hereafter conferred by statute or otherwise which may require
Lessor to sell or lease or otherwise use the equipment in mitigation of Lessor's
damages or losses or which may otherwise limit or modify any of Lessor's rights
or remedies under this Lease.

20.       LESSOR'S RIGHT TO PERFORM.

          If Lessee fails to make any payment required to be made by it
hereunder or fails to perform or comply with any of its other agreements
contained herein, Lessor may itself make such payment or perform or comply with
such agreement, and the amount of such payment and the amount of the reasonable
expenses of Lessor incurred in connection with such payment or the performance
of or compliance with such agreement, as the case may be, together with interest
thereon at the Late Charge Rate, shall be deemed to be additional rent, payable
by Lessee within 30 days of notice.

21.       LOCATION; ASSIGNMENT OR SUBLEASE; TITLE TRANSFER.

          (a) LESSEE WILL NOT REMOVE THE EQUIPMENT FROM THE LOCATION SPECIFIED
IN SCHEDULE 1 OF EXHIBIT A WITHOUT THE PRIOR WRITTEN CONSENT OF LESSOR, SUCH
CONSENT NOT TO BE UNREASONABLY WITHHELD, EXCEPT REMOVAL OUTSIDE THE CONTINENTAL
U.S. IS NOT PERMITTED. THE EQUIPMENT SHALL AT ALL TIMES BE IN THE SOLE
POSSESSION AND CONTROL OF LESSEE AND LESSEE WILL NOT, WITHOUT THE PRIOR WRITTEN
CONSENT OF LESSOR, ASSIGN THIS LEASE OR ANY INTEREST HEREIN OR SUBLEASE OR
OTHERWISE TRANSFER ITS INTEREST IN ANY OF THE EQUIPMENT, AND ANY ATTEMPTED
ASSIGNMENT, SUBLEASE OR OTHER TRANSFER BY LESSEE IN VIOLATION OF THESE
PROVISIONS SHALL BE VOID.

          (b) LESSOR AND LESSEE ACKNOWLEDGE THAT LESSOR (i) MAY TRANSFER ITS
INTEREST IN THE EQUIPMENT TO AN OWNER OTHER THAN LESSOR. LESSOR  MAY
CONTEMPORANEOUSLY THEREWITH LEASE THE EQUIPMENT BACK FROM SUCH OWNER AND (ii)
MAY ASSIGN THIS LEASE. LESSEE HEREBY CONSENTS TO EACH OF THE ABOVE-DESCRIBED
TRANSACTIONS, FURTHER LESSEE DOES HEREBY ACKNOWLEDGE (i) THAT ANY SUCH TRANSFER
AND/OR ASSIGNMENT BY LESSOR DOES NOT MATERIALLY CHANGE LESSEE'S DUTIES AND
OBLIGATIONS HEREUNDER. (ii) THAT SUCH TRANSFER AND/OR ASSIGNMENT DOES NOT
MATERIALLY INCREASE THE BURDENS OR RIGHTS IMPOSED ON THE LESSEE, AND (iii) THAT
THE ASSIGNMENT IS PERMITTED EVEN IF THE ASSIGNMENT COULD BE DEEMED TO MATERIALLY
AFFECT THE INTEREST OF THE LESSEE.

22.       STATUS CHANGES IN LESSEE.

          Lessee will not without thirty (30) days prior written notice to
Lessor, (a) enter into any transaction of merger or consolidation unless it is
the surviving corporation or after giving effect to such merger or consolidation
its net worth equals or exceeds that which existed prior to such merger or
consolidation; or (b) change the form of organization of its business; or (c)
change its name or its chief place of business. Lessee must obtain Lessor's
prior written concurrence before Lessee may undertake any actions to (a)
liquidate, dissolve or any such similar action of the Lessee's organization, or
(b) sell, transfer or otherwise dispose of all or any substantial part of
Lessee's assets.

     (a) Lessee will, at its expense, promptly and duly execute and deliver to
Lessor such further documents and assurances and take such further action as
Lessor may from time to time reasonably request in order to establish and
protect the rights, interests and remedies created or intended to be created in
favor of Lessor hereunder, including, without limitation, the execution and
filing of Uniform Commercial Code financing statements covering the equipment
and proceeds therefrom in the jurisdictions in which the equipment is located

standing, in each jurisdiction in which the equipment is from time to time

shall be true and correct on and as of the date of this Lease with the same
force and effect as if made on and as of such date; no Event of Default or
Default shall be in existence on such date or shall occur as a result of the
lease by Lessee of the equipment specified in Schedule I of Exhibit A;

               (iii) In the sole judgment of Lessor, there shall have been no
material adverse change in the financial condition or business of Lessee;

               (iv) All proceedings to be taken in connection with the
transactions contemplated by this Lease, and all documents incidental thereto,
shall be satisfactory in form and substance to Lessor and its counsel;

               (v) Lessor shall have received from Lessee, in form and substance

27.  LIMITATION OF LIABILITY.

     LESSOR SHALL NOT BE LIABLE FOR LOST PROFITS OR REVENUE, SPECIAL, INDIRECT,
INCIDENTAL, CONSEQUENTIAL OR PUNITIVE DAMAGES OF ANY NATURE OR FROM ANY CAUSE
WHETHER BASED IN CONTRACT OR TORT, INCLUDING NEGLIGENCE, OR OTHER LEGAL THEORY
EVEN IF LESSOR HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.  LESSEE
HEREBY AGREES THAT LESSOR WILL NOT BE LIABLE FOR ANY LOST PROFITS OR REVENUE OR
FOR ANY CLAIM OR DEMAND AGAINST LESSEE BY ANY OTHER PARTY.

28.  MISCELLANEOUS.

     (a) Any provision of this Lease which is prohibited or unenforceable in 
any jurisdiction shall, as to such jurisdiction, be ineffective to the extent 
of such prohibition or unenforceability without invalidating the remaining 
provisions hereof, and any such prohibition or unenforceability in any 
jurisdiction shall not invalidate or render unenforceable such provisions in 
any other jurisdiction.  To the extent permitted by applicable law, Lessee 
hereby waives any provision of law which renders any provision hereof 
prohibited or unenforceable in any respect.

     (b) No items or provisions of this Lease may be changed, waived, discharged
or terminated orally, but only by an instrument in writing signed by the party
against which the enforcement of the change, waiver, discharge or termination is
sought.  No delay or failure on the part of Lessor to exercise any power or
right hereunder shall operate as a waiver thereof, nor as an acquiescence in any
default, nor shall any single or partial exercise of any power or right preclude
any other or further exercise thereof, or the exercise of any other power or
right.  After the occurrence of any Default or Event of Default, the acceptance
by Lessor of any payment of rent or other sum owed by Lessee pursuant hereto
shall not constitute a waiver by Lessor of such Default or Event of Default,
regardless of Lessor's knowledge or lack of knowledge thereof at the time of
acceptance of any such payment, and shall not constitute a reinstatement of this
Lease, if this Lease shall have been declared in default by Lessor pursuant to
Section 18 hereof or otherwise, unless Lessor shall have agreed in writing to
reinstate the Lease and to waive the Default or Event of Default.

In the event Lessee tenders payment to Lessor by check or draft containing a
qualified endorsement purporting to limit or modify Lessee's liability or
obligations under this Lease, such qualified endorsement shall be of no force
and effect even if Lessor processes the check or draft for payment.

     (c) This Lease with exhibits contains the full, final and exclusive
statement of the agreement between Lessor and Lessee relating to the lease of
the equipment.

     (d) This Lease shall constitute an agreement of an operating lease, and
nothing herein shall be construed as conveying to Lessee any right, title or
interest in the equipment except as Lessee only.

     (e) This Lease and the covenants and agreements contained herein shall
be binding upon, and inure to the benefit of, Lessor and its successors and
assigns and Lessee and, to the extent permitted by Section 21 hereof, its
successors and assigns.

     (f) The heading of the Sections are for convenience of reference only, are
not a part of this Lease and shall not be deemed to affect the meaning or
construction of any of the provisions hereof.

     (g) This lease may be executed by the parties hereto on any number of
separate counterparts, each of which when so executed and delivered shall be an
original, but all such counterparts shall together constitute but one and the
same instrument.

     (h) This Lease is deemed made and entered into the State of Florida and
shall be governed by and construed under and in accordance with the laws of the
State of Florida as if both parties were residents of Florida.

     (i) Lessee hereby irrevocably consents and agrees that any legal action,
suit, or proceeding arising out of or in any way in connection with this Lease
shall be instituted or brought in the courts of the State of Florida, or in the
United States Courts for the District of Florida, and by execution and delivery
of this Lease, Lessee hereby irrevocably accepts and submits to, for itself and
in respect of its property, generally and unconditionally, the non-exclusive
jurisdiction of any such court, and to all proceedings in such courts.  Lessee
irrevocably consents to service of any summons and/or legal process by
registered or certified United States mail, postage prepaid, to Lessee at the
address set forth in Section 24 hereof, such method of service to constitute, in
every respect, sufficient and effective service of process in any legal action
or proceeding.  Nothing in this Lease shall affect the right to service of
process in any other manner permitted by law or limit the right of Lessor to
bring actions, suits or proceedings in the court of any jurisdiction.  Lessee
further agrees that final judgment against it in any such legal action, suit or
proceeding shall be conclusive and may be enforced in any other jurisdiction,
within or outside the United States of America, by suit on the judgment, a
certified or exemplified copy of which shall be conclusive evidence of the fact
and the amount of the liability.

               -hereinafter referred to as Lessee-

the following Lease is signed:

                                   SECTION 1
                                LEASED PROPERTY

1.  ACCORDING TO THE GROUND PLAN ATTACHED AS APPENDIX, which forms part of 
    this Lease, Lessor grants Lessee a Lease of the following areas for the 
    establishment of an office business within the building Prinzenallee 7, 
    erected on the premises Prinzenallee 5-21/Hansaallee 101,40549 Dusseldorf:

a)  PRINZENALLEE 7, OFFICE AREA ON THE GROUND FLOOR OF APPROX. 1,122.12 m(2)

b)  PRINZENALLEE 7, OFFICE AREA IN THE BASEMENT OF APPROX. 112,09 m(2)

c)  PRINZENALLEE 7, STORAGE AREA IN THE BASEMENT OF APPROX. 124.76 m(2)

d)  6 PARKING SPACES IN THE UNDERGROUND CAR PARK (NOS. 391 TO 396)

e)  2 PARKING SPACES OUTSIDE (NO. 29 AND 30)


2.  In the ground plans attached AS APPENDIX, the leased areas according to 
    subparagraph 1 a) TO c) are marked in red outline and determined by the 
    area between the inside of the demarcation walls of the building, so that 
    possibly existing movable lightweight or partition walls and interior 
    stairs as well as other similar building components are not deducted but 
    regarded as leased area. Non-usable traffic areas and suchlike have been 
    taken into consideration when calculating the amount of rent.

    The areas mentioned in sub-paragraph 1 d) AND e) are determined bindingly 
    by the two parties, so that the location can be taken from plans as well.

    If a later measurement results in deviations of less than 2.5%, none of 
    the two parties shall be entitled to demand an adjustment of rent for 
    this reason.

<PAGE>

3.  The ground plan serves exclusively for determining the situation of the 
    Leased Property.

4.  The Leased Property is provided ACCORDING TO THE GROUND PLAN ATTACHED AS 
    APPENDIX, interior works completed.

    Lessor reserves the right of minor alterations which do not interfere 
    with Lessee's business operation or which are advisable on the basis of 
    conditions imposed by the authorities or technical requirements.

    Lessee shall take into account the necessary escape routes when 
    establishing and operating the Leased Property - if necessary according 
    to Lessor's instructions - and to keep them permanently clear for 
    unhindered passage.

    On the occasion of handing over, a handing over protocol shall be 
    prepared. Any possible defects, considerably reducing the Leased 
    Property's suitability for contractual use, are to be listed therein. 
    These defects are to be remedied by Lessor within a reasonable period of 
    time. 

    By taking over, Lessee agrees that in other respects, the Leased Property 
    is in a condition suitable for contractual use.

5.  To the extent that Lessee requires alterations to the Leased Property 
    exceeding those of the present equipping and of the GROUND PLAN ATTACHED 
    AS APPENDIX, these alterations are subject to Lessor's prior written 
    consent in each individual case. Consent may be denied for substantial 
    reasons only. If consent is granted, Lessee may carry out these 
    alterations at its own expense.

    Lessee shall have these works carried out in accordance with Lessor's 
    supervision of works. Lessor is entitled to make its consent dependent on 
    compliance with supplementary terms.

6.  Lessor does not warrant that the leased areas have been designed 
    according to ground plan down to the last detail.

7.  The carrying capacity of the ceilings is:

    - on the ground floor                     =500 kg/m(2)
    - on the first floor to upper story       =350 kg/m(2)
    including allowance for partition walls.

                                   SECTION 2 
                              BEGINNING OF LEASE

1.  The Lease begins on the handing over date, probably on

                              JANUARY 1ST, 1998

2.  The contractual relationship shall begin on signing the contract, the 
    Lease on handing over.

3.  The construction period required for special facilities and special 
    requests of Lessee is to be regarded as rental period, unless its 
    execution runs parallel to the completion to be effected by Lessor 
    requiring additional time.

                                       SECTION 3
                                   DURATION OF LEASE

1.  The Lease is contracted for a duration of ten years. It begins on handing 
    over.

2.  LESSOR GRANTS LESSEE THE OPTION TO RENEW THE LEASE FOR ANOTHER FIVE YEARS.
    LESSEE'S DECLARATION TO EXERCISE ITS RIGHT OF OPTION HAS TO BE RECEIVED BY
    LESSOR NOT LATER THAN 12 MONTHS PRIOR TO EXPIRY OF THE TENTH YEAR OF 
    CONTRACT. THE DECLARATION MUST BE MADE IN WRITING.

3.  WHEN LESSEE REMAINS IN POSSESSION OF THE LEASED PROPERTY AFTER EXPIRY OF 
    THE LEASE, THE LEASE IS NOT TO BE REGARDED AS RENEWED. SECTION 568 GERMAN
    CIVIL CODE BGB IS NOT APPLICABLE. CONTINUATION OR RENEWAL OF LEASE AFTER 
    ITS TERMINATION MUST BE AGREED IN WRITING.


                                     SECTION 4
                                    CANCELLATION

1.  Lessor is entitled to terminate the Lease without notice, if and when

a)  Lessee is in arrears with the payment of rent and/or payment of costs 
    according to Section 6 of this contract despite written reminder, with a 
    sum REACHING the amount of two monthly rents (see Section 6, sub-paragraph
    1) or, in the case of incidental expenses, the quarterly payment.

b)  Lessee continues to use the property in a manner contrary to the terms of 
    the Lease, or if Lessee otherwise considerably or lastingly infringes the 
    rights of Lessor or other lessees, or leaves the Property to a third 
    party without authorization, and if it fails to take corrective action 
    despite written caution by registered letter specifying a reasonable time 
    limit.

c)  a petition in bankruptcy or for the institution of composition 
    proceedings has been filed with respect to Lessee's assets, or if a 
    petition in bankruptcy is dismissed for lack of assets or if Lessee has 
    otherwise suspended payments or enters into extrajudicial composition 
    proceedings.

d)  the contractually agreed type of use is changed without Lessor's consent 
    and no corrective action is taken despite written caution by registered 
    letter specifying a reasonable time limit.

2.  LESSEE IS ENTITLED TO TERMINATION OF LEASE WITHOUT NOTICE, PROVIDED 
    LESSOR FAILS TO COMPLY WITH ESSENTIAL CONTRACTUAL OBLIGATIONS DESPITE 
    WRITTEN CAUTION SPECIFYING A REASONABLE TIME LIMIT OR IF CIRCUMSTANCES AS 
    DESCRIBED UNDER SECTION 4, SUBPARAGRAPH 1.c) ARE APPLICABLE TO LESSOR.

3.  The notice of termination must be given in writing. It becomes effective 
    on receipt.

<PAGE>

4.  In the case of premature termination of Lease subject to Lessee's 
    responsibility, Lessee shall be liable for the loss of rent, incidental 
    expenses and other payments for the contractual duration of Lease as well 
    as for any other loss suffered by Lessor due to the premature 
    cancellation of Lease with respect to the Leased area, unless Lessor is 
    indemnified by a new, adequate lease of the rooms. THE COSTS ACCRUED IN 
    THIS RESPECT (IN PARTICULAR INSERTION EXPENSES AND BROKER'S COMMISSION) 
    ARE TO BE BORNE BY LESSEE. LESSOR SHALL MAKE ANY EFFORT TO FIND A 
    SUITABLE NEW LESSEE. IT WILL ACCEPT A NEW LESSEE PRESENTED BY LESSEE, 
    PROVIDED THE NEW LESSEE EQUALS LESSEE WITH RESPECT TO KIND OF BUSINESS AND
    FINANCIAL SOUNDNESS.


                                  SECTION 5
                       OBLIGATIONS ON TERMINATION OF LEASE

1.  On termination of Lease on any legal ground whatsoever, Lessee shall 
    return the Leased Property to Lessor in an expertly renovated and cleaned 
    condition, not later than on the last calendar day of the rental period. 
    The obligation to renovate does not refer to normal wear and tear 
    regarding roof and compartment of the Property. IN OTHER RESPECTS, IT 
    ONLY REFERS TO THOSE ITEMS CLASSIFIED AS SUBJECT TO DECORATIVE REPAIRS 
    ACCORDING TO SECTION 28, SUB-PARAGRAPH 4, SENTENCE 5 II OF THE OPERATING 
    AGREEMENT BV (AS AMENDED ON OCT. 12, 1990), AND TO CARPETS, IF THESE HAD 
    BEEN PROVIDED BY LESSOR ON MOVE.

2.  By the end of the rental period, Lessee shall have removed any 
    installations and structural alterations executed by Lessee prior to or 
    after moving in, and Lessee shall restore the state of the building 
    originally planned or existing. If and to such an extent as allowed by 
    Lessor, Lessee is entitled not to remove installations or structural 
    alterations. In this case, Lessor is entitled  to acquire them, wholly or 
    in part, against payment of A REASONABLE compensation. THIS DOES NOT 
    APPLY TO ANY OBJECTS SUBJECT TO LESSOR'S CONTRIBUTION TO EXPENSES ON 
    FITTING OUT UNDER SECTION 17, SUB-PARAGRAPH 1 OF THIS LEASE. The 
    obligation to execute decorative repairs according to Section 10 remains 
    unaffected.

3.  Additionally, Lessee shall indemnify for any loss suffered by Lessor due 
    to delayed return of the leased rooms.

4.  On Lessor's demand to remove the installations/alterations, Lessee is 
    obligated to restore the original condition, or the condition originally 
    agreed, at its own expense, including each and every necessary secondary 
    work.


                                 SECTION 6
                                 SUBLEASING

1.  Lessor is entitled to sublease or sublet the Leased Property, subject to 
    Lessor's prior written consent, but only

a)  for the same or similar purposes of use, for which the rooms are leased 
    to Lessee and

b)  to a sublessee convenient to Lessor. Lessor may reject a sublessee only, 
    if sublessee's person, branch of business or company gives substantial 
    cause for such a rejection.

2.  Subleasing for the purpose of a changed use of the Leased Property 
    requires Lessor's special written consent.

                                  SECTION 7
                   AMOUNT OF RENT AND INCIDENTAL EXPENSES

1.  The monthly rent for the leased areas shown in Section 1 amounts to

a)  approx. 1,122.12 m(2)         X DM 27.50 = DM 30,858,30

b)  approx.   112.09 m(2)             X DM 20.00 = DM 2,241.80 (offices)

c)  approx.   124.76 m(2)             X DM 12.00 = DM 1,497.12 (storage area 1)

d)  6 parking spaces undergr.c.p.     X DM 110.00 = DM  660.00

e)  2 parking spaces outside          X DM  60.00 = DM  120.00
    ----------------------------------------------------------


    total                                         = DM 35,377.22
                                                    ------------
                                                    ------------


LESSOR ALLOWS LESSEE THE USE OF THE LEASED PROPERTY FREE OF RENT FOR THE 
FIRST THREE MONTHS OF LEASE AFTER HANDING OVER (POSSIBLY EARLIER REGARDING 
PARTIAL AREAS), NOT LONGER, HOWEVER, THAN UNTIL MARCH 31ST, 1998. THE ADVANCE 
PAYMENT FOR THE OPERATING EXPENSES IS DUE ON HANDING OVER OF THE RESPECTIVE 
LEASED AREA (INCLUDING PARTIAL AREAS).

2.  The incidental expenses listed in the following are not covered by the 
rent payment:

    -  real estate and building insurance
    -  real property tax
    -  cost of water and waste water
    -  cleaning expenses streets, paths and squares
    -  upkeep of decorative elements and of general green areas including 
    purchasing costs of new plants
    -  costs of fire alarm and extinguishing systems, safety contrivances of 
    all kinds (if available)
    -  costs of caretaker or in-house technician
    -  costs of house cleaning 
    -  costs of the heating system including consumption 
    -  general current, lamps
    -  metering and accounting expenses of consumption 
    -  elevator costs
    -  refuse collection - unless separate agreement
    -  cost of ventilation, air conditioning equipment
    -  wide band supply 
    -  upkeep and repair of interior and exterior general areas, except for 
    roof, outer facades and load-bearing elements

<PAGE>

    -  house management

    Lessee shall bear these costs according to actual consumption or to the 
    corresponding expenses incurred.

    Industrial waste, e.g. office paper, overstepping the mark, is to be 
    removed by Lessee.

    To the extent that costs are apportioned, Lessee shall be treated as 
    equivalent to the other lessees (applying the same basis for allocation), 
    irrespective of the operating expenses.

    A monthly advance payment of DM 5.50 per m(2) shall be collected for the 
    above mentioned incidental expenses for the offices and the supplementary 
    area. This advance payment is to be effected together with the rent 
    payment. In the case of a change of these incidental expenses or if new 
    real property liens arise, Lessor shall be entitled to reassess the 
    advance payments.

    Settlement of accounts with respect to the advance payments will be 
    effected once a year. If the settlement of accounts shows an overpayment, 
    a corresponding credit note in favor of Lessee will be issued. If the 
    costs to be settled exceed the advance payments, Lessor shall claim a 
    corresponding payment. Provided economically justifiable, corresponding 
    supply meters are to be installed for the determination of consumption. 
    Unless a direct determination of such costs is possible, Lessee shall be 
    charged with these costs in proportion of its leased area to the overall 
    leased area of the Property. In the case of a breakdown of the metering 
    devices or if such devices do not work properly, Lessor is entitled to 
    allocate costs by way of assessment.

    The accounting documents shall be available for inspection according to 
    Lessor's provisions for one month after dispatch of the settlement of 
    accounts to lessees.

3.  Lessee shall pay a monthly flat charge of 1% of the net rent agreed under 
    Section 7, sub-paragraph 1, for the proportionate administrative expenses.

4.  In addition to the rent, any value added tax to the extent assessed and 
    due shall be owed by Lessee. This also applies to incidental and 
    administrative expenses listed above.


                                   SECTION 8 
                    PAYMENT OF RENT AND INCIDENTAL EXPENSES

1.  The rent and the advance payment for incidental and administrative 
    expenses are to be paid to Lessor or to a person or institution 
    authorized by lessor for acceptance monthly in advance not later than on 
    the third working day of the respective month. For the first time, these 
    payments are to be effected for the period from the day of handing over 
    the Leased Property.

2.  On delay in payment, Lessor is entitled to charge default interest of 4% 
    above the respective discount rate of the Deutsche Bundesbank as well as 
    dunning costs to the extent of DM 5.00 PER REMINDER. The assertion of 
    further damages caused by delay remains unaffected.

3.  In the case of partial payments on the part of Lessee, Lessor is entitled 
    to offset according to Section 366 II German Civil Code BGB, irrespective of
    any statements by Lessee.

4.  Lessor shall not pay any interests on advance payments for incidental 
    expenses.

5.  THE RETENTION OF PAYMENTS TO BE EFFECTED BY THE PARTIES UNDER THIS 
    CONTRACT AND THEIR OFFSET AGAINST ANY CLAIMS IS EXCLUDED, UNLESS 
    ACKNOWLEDGED OR RECOGNIZED BY DECLARATORY JUDGEMENT BY THE OTHER PARTY. 
    LESSEE'S RIGHT TO CLAIM REDUCTION OF RENT REMAINS UNAFFECTED.

                         RENT ADJUSTMENT/VALUE GUARANTY

1.  The rent agreed under Section 6, sub-paragraph 1 is to be considered as 
    fixed until December 31st, 1998. After that date, it shall be increased 
    or reduced in percentages for the following year according to 
    cost-of-living index of an employee's family of four with an average 
    income of the sole breadwinner, as published by the Statistisches 
    Landesamt NRW (Land Statistical Office of North Rhine-Westphalia) on the 
    basis of 1991 = 100 points, with 75% corresponding to the increase or 
    decrease of the index.

2.  A FIRST ADJUSTMENT OF RENT WILL BE EFFECTED ON JANUARY 1ST, 1999. THE 
    CHANGE OF INDEX FROM DECEMBER 1997 (BASE INDEX) TO DECEMBER 1998 IS 
    AUTHORITATIVE FOR THIS ADJUSTMENT. SUBSEQUENTLY, THE RENT ADJUSTMENT 
    SHALL BE EFFECTED ON JANUARY 1ST OF EACH YEAR OF LEASE, ALSO ACCORDING TO 
    THE RESPECTIVE CHANGE OF INDICES FROM DECEMBER OF THE PREVIOUS YEAR IN 
    RELATION TO DECEMBER OF THE YEAR BEFORE.

    In the following years of Lease, a corresponding adjustment of rent shall 
    be effected on January 1st respectively.

2.  If in future this adjustment becomes legally impossible for any reason 
    whatsoever, e.g. because this index is no longer officially determined or 
    published or if the connection hereto becomes legally impossible for any 
    reason whatsoever, the contracting parties are bound to come to an 
    agreement on a reasonable adjustment of rent which is permitted by 
    statute and the content of which is economically as similar as possible 
    to the value clause agreed hereunder.

3.  The contracting parties are aware of the fact that the legal effect of the 
    above value clause is dependent on the approval by the Land central bank. 
    Lessor will endeavor immediately to obtain such approval. The legal 
    effect of the other provisions of this contract remain unaffected, as 
    long as the approval by the Land central bank has not been obtained or if 
    it is denied. In that case, the contracting parties are bound to work on 
    a permissible wording in order to achieve a corresponding rent 
    restriction to the development of the cost of living.


                                  SECTION 10
                             MAINTENANCE AND REPAIR

1.  On beginning of contract, the leased rooms are handed over to Lessee in a 
    new, perfect condition. Prior to move, any possible defects are recorded 
    in a handing

<PAGE>

    over protocol. During the rental period, the leased rooms are to be kept 
    in a proper, unobjectionable condition and are to be treated with care.

2.  During the rental period, Lessee shall additionally be responsible for 
    all repairs within the Leased Property caused by its own fault or by 
    inexpert handling (repair, maintenance) and for all the interior 
    decorative repairs. Lessee shall perform expert interior decorative 
    repairs at its own expense at reasonable intervals, not later than every 
    3 years.

3.  Lessee shall remove immediately any damages, he is responsible for. If 
    Lessee fails to comply with this provision within a reasonable period of 
    time, Lessor may have the necessary works executed at Lessee's expense.

4.  In the case of damages causing any imminent dangers or in the case of 
    unknown abode of Lessee, a written caution or the fixing of time limit is 
    not required. In such cases, Lessor is entitled to execute damage removal 
    at Lessee's expense.


                                      SECTION 11
                                 INSURANCE, LIABILITY

1.  Insurance of Lessee's fittings and of stored assets against fire, water, 
    burglary and housebreaking or other damages is within Lessee's 
    responsibility.

2.  In particular, Lessee is liable for the following damages to the Leased 
    Property:

a)  any damages to the fittings and other objects brought in by Lessee, 
    caused by fire or tap water, including the risks of sewage water and 
    inappropriate penetration of sprinkler water;

b)  any personal injury and damage to property to an extent customary in 
    Lessee's line of business

c)  broken glass

d)  any damages resulting from burglary and housebreaking.

3.  Lessee shall effect insurances covering the risks mentioned under a-d.

    Lessor may demand presentation of the corresponding insurance policies in 
    regular intervals, including a written declaration by the insurance 
    company confirming that a corresponding examination has not shown a case 
    of underinsurance.

4.  Lessor assumes no liability whatsoever for any possible damages to 
    fittings, unless the damage has been NEGLIGENTLY caused by Lessor or by 
    its vicarious agents. LESSOR, HOWEVER, SHALL BE LIABLE FOR ANY DEFECTS, 
    LESSEE IS EXPRESSLY NOT LIABLE FOR ACCORDING TO THE FOLLOWING.

5.  In the case of subleasing, Lessee shall indemnify Lessor against any 
    claims to such an extent as such claims against Lessor are excluded for 
    Lessee itself according to the terms of this contract. This also applies 
    to non-contractual foundations for claims.

6.  LESSEE IS LIABLE FOR ANY DAMAGES NEGLIGENTLY CAUSED BY ITS FAILURE TO 
    EXERCISE PROPER CARE, INCLUDING WITHOUT LIMITATION, IN PARTICULAR, 
    INEXPERT HANDLING OF SUPPLY PIPES OR DRAINS, TOILETS AND HEATING PLANTS 
    OR OF ELECTRICAL EQUIPMENT WITHIN THE LEASED ROOMS, AND FAILURE TO 
    PROTECT THEM SUFFICIENTLY FROM FROST OR OTHER INFLUENCES. AT ALL EVENTS, 
    OCCLUSIONS OF PIPES ARE TO BE REMOVED BY LESSEE UP TO THE MAIN PIPE AT 
    ITS OWN EXPENSE.
<PAGE>

7.  IN THE SAME WAY, LESSEE IS LIABLE FOR ANY DAMAGES NEGLIGENTLY CAUSED TO 
    THE PROPERTY BY ITS EMPLOYEES OR SUBLESSEES. IF SUCH A DAMAGE IS CAUSED 
    BY LESSEE'S OR SUBLESSEE'S VISITORS OR SUPPLIERS, LESSEE IS LIABLE ONLY, 
    IF IT FAILS TO INFORM LESSOR ABOUT THE FULL NAME AND ADDRESS OF THE 
    VISITOR OR SUPPLIER (SPECIFIC EXECUTING PERSON).

    LESSEE SHALL MAINTAIN ANY PIPES AND PLANTS RELATING TO ELECTRICITY, GAS 
    AND SANITATION, LOCKS, BLINDS, AND SIMILAR EQUIPMENT IN A SERVICEABLE 
    CONDITION.

    LESSEE IS FURTHER LIABLE FOR ANY DAMAGES CAUSED BY INEXPERT HANDLING OF 
    WATER, LIGHT AND POWER MAINS, AND FOR ANY DAMAGES TO TOILETS, SANITATION 
    OR HEATING PLANT AS WELL AS VENTILATION, SMOKE ALARMS AND ACOUSTIC 
    EQUIPMENT (IF AVAILABLE) CAUSED BY LEAVING DOORS OPEN, BY STRUCTURAL 
    MEASURES TAKEN BY LESSEE, BY ADVERTISING EQUIPMENT INSTALLED BY LESSEE OR 
    BY FAILURE TO COMPLY WITH THE OTHER OBLIGATIONS ASSUMED BY LESSEE.

    Lessee is liable to Lessor for any damages to buildings, doors, gates, 
    elevators, parking lots, traffic ways etc., caused by delivery traffic 
    and exceeding customary wear and tear.

8.  AT ALL EVENTS, LESSOR SHALL REPLACE AT ITS OWN EXPENSE ANY DAMAGED GLASS 
    PANES AND MIRRORS AND IF NECESSARY, LESSOR SHALL EFFECT A GLASS 
    INSURANCE. NOT CLOSING TOILETS AND SINKS, CAUSING WATER TO FLOW 
    CONTINUOUSLY THROUGH LEAKY VALVES THUS RESULTING IN CONSIDERABLE WATER 
    CONSUMPTION, ARE IMMEDIATELY TO BE REPORTED TO LESSOR. DELAYED REPORTS 
    MAY RESULT IN DAMAGE CLAIMS. ON REQUEST, ANY POSSIBLE CLAIMS AGAINST 
    THIRD PARTIES AT FAULT ARE ASSIGNED TO LESSOR BY LESSEE.

9.  Lessee is responsible for not exceeding the indicated carrying capacity 
    of the bearing plate.

10. Lessee shall immediately remove any damages it is responsible for 
    according to the above provisions at its own expense. On Lessee's 
    failure to do so despite written caution and fixing of an appropriate time 
    limit by Lessor, Lessor may have the corresponding work executed at 
    Lessee's expense. In the case of damages causing any imminent dangers or 
    in the case of unknown abode of Lessee, a written caution or fixing of 
    time limit is not required.

11. Lessor shall arrange for the examination of plants jointly used by 
    several lessees or belonging to the commonly used facilities. Lessor is 
    entitled to sign appropriate fully comprehensive maintenance agreements. 
    Costs shall be apportioned to the lessees. The required examination of 
    plants exclusively used by Lessee or installed by Lessee is to be arranged 
    for by Lessee at its own expense. Lessee is obligated to observe and 
    comply with each and every statutory or public law provision with respect 
    to its place of business.

<PAGE>

12. Plants and components left for Lessee's sole use are to be maintained, 
    attended to and kept up in such a way, that they are returned in a 
    serviceable condition after termination of contract.


                                    SECTION 12
                          PREMATURE TERMINATION OF LEASE

1.  Lessor generally agrees to give its consent to annulment of contract in 
    the case that Lessee demands early termination of contract for 
    substantial reasons, provided that Lessee presents an equivalent and 
    solvent new lessee with whom a contract of lease is entered into, in which 
    the new lessee succeeds to each and every right and obligation under this 
    contract.

    The new lessee's use of the Leased Property for other than the previous 
    purposes is subject to Lessor's consent. Lessor may deny such consent, 
    if any non-competitive clauses agreed by Lessor or justified interests of 
    other lessees or the mixture of branches are adverse to such use.

2.  Additionally, a precondition for Lessor's consent is that Lessee or the 
    new lessee binds itself by contract with Lessor to bear all the expenses 
    involved in the change of lessee (including commercial agency's charges) 
    and finally that Lessee assumes the absolute guaranty for the performance 
    of the financial obligations of the new lessee against Lessor for the 
    time up to the first possible date of termination.


                                  SECTION 13
                STRUCTURAL ALTERATIONS AND INSTALLATIONS BY LESSEE

1.  Prior to and during the rental period, any structural alterations within 
    and outside the leased rooms are subject to Lessor's written consent. 
    Lessee is entitled to install advertising writings or signs in areas of 
    the Leased Property earmarked by Lessor. In order to achieve a uniform 
    design of the overall property, however, Lessee is obligated to have such 
    exterior advertising approved by Lessor in advance. Any possible official 
    permits required are to be obtained in advance by Lessee at its own 
    expense. Even if Lessor grants its consent to structural alterations and 
    installations, Lessee is obligated to remove such installations and to 
    restore the original condition on termination of Lease.

    Subject to Lessor's consent, Lessee may leave any objects affixed to the 
    building to Lessor free of charge. Lessee may also have its company name 
    installed in the entrance area of the building at its own expense, 
    uniform with the other users of the building and in accordance with 
    Lessor (a uniform sign board is planned for all the lessees, divided up 
    into individual signs).

    Lessee is entitled to equip the rooms at its own expense with additional 
    installations and special facilities which are useful and necessary for 
    the performance of its business.

    As soon as possible after completion of the contract, Lessee shall draw 
    up a catalogue with such items and submit it to Lessor for approval. 
    Planning, installation or delivery of Lessee's special facilities is 
    within Lessee's responsibility. In agreement with Lessor's architect, 
    however, it may make use of his expert assistance against payment of a 
    reasonable remuneration.



<PAGE>

2.  Regarding the electric installations required and ordered by Lessee, which 
    are subject to VDE/TUV, Lessee is obligated to entrust an expert company. 
    Upon Lessor's demand, Lessee shall present the electricity plans. 

                                   SECTION 14
                   REPAIR AND STRUCTURAL ALTERATIONS BY LESSOR

1.  Even without Lessee's consent, Lessor may perform any repairs and 
    structural alterations becoming necessary for the maintenance of the 
    building or of the Lease Property, for averting imminent dangers, for 
    the removal of damages or because of other lessees moving in/out. 

    This shall also apply to works which are not necessary but useful, as for 
    instance modernization of the building and of the Leased Property. DURING 
    THE FIRST TEN YEARS OF LEASE, A MODERNIZATION OF LESSEE'S ROOMS IS 
    SUBJECT TO LESSEE'S PRIOR CONSENT. Lessee shall maintain accessible the 
    rooms concerned. Lessee must not hinder or delay the execution of the 
    works.

2.  Provided Lessee is bound to tolerate the works, it is not entitled to 
    rent reduction nor to exercise a right of retention. Lessor, however, is 
    obligated to have such works executed outside Lessee's usual business 
    hours, if possible, in order to avoid a substantial interference with 
    Lessee's business operation.


                                   SECTION 15
                       JURISDICTION AND PLACE OF PERFORMANCE

1.  Place of jurisdiction and place of performance is Dusseldorf.


                                   SECTION 16
                                SECURITY FOR RENT

1.  Lessee shall provide a guaranty to the extent of SIX NET MONTHLY RENTS to 
    provide security for its obligations under this contract. This guaranty 
    may be effected in the form of a bank guaranty issued for an unlimited 
    period of time. On termination of Lease, the security is returned to the 
    full extent, provided this contract of Lease is perfectly fulfilled and 
    all other obligations in connection with this Lease are complied with. 
    Otherwise, the security provided shall be set off against Lessor's claims.

    Lessor may demand that the suretyship is increased corresponding to a 
    rent increase as per Section 8 of this contract. Accordingly, the 
    security is to be increased on Lessor's first demand in such a way, that 
    it always matches SIX current net monthly rent payments.

<PAGE>

2.  If the security or an appropriate guaranty is not received by Lessor 
    within 14 days after handing over of contract, Lessor is entitled to 
    withdraw from contract after another written caution of 14 days.


                                    SECTION 17
                                SPECIAL CONDITIONS

1.  LESSEE IS GRANTED AN ADDITIONAL CONTRIBUTION TO EXPENSES ON FITTING OUT 
    IN THE GROSS AMOUNT OF DM 350,000.00, IN ADDITION TO THE CONVENTIONAL 
    DESIGN.

    THIS CONTRIBUTION MAY BE USED FOR FALSE FLOOR, AIR CONDITIONING IN 
    VARIOUS AREAS, ADDITIONAL STEEL DOORS AND FOR ADDITIONAL LAMPS AND OTHER 
    SPECIAL REQUIREMENTS, WHICH ARE NOT INCLUDED IN THE STANDARD BUILDING 
    SPECIFICATIONS.

2.  Lessor assumes the obligation of cleaning the pavement including snow 
    removal and gritting in icy weather of the pavements and pedestrian areas 
    in front of the building, complying with the municipality's provisions. 
    The corresponding expenses will be apportioned to the lessees in 
    accordance with Section 6, sub-paragraph 2.

3.  Lessee agrees furthermore to clean windows and window frames regularly. 
    This also applies to sun protection facilities. If cleaning contractors 
    are entrusted with attending to the overall property, Lessee may join 
    such an agreement, provided it bears the proportionate expenses.

4.  The house regulations attached form part of this Lease and shall be signed 
    by the two parties as well. The legal provisions shall apply 
    supplementary to these terms of contract.

5.  Annulment, amendments and supplements to this contract must be made in 
    writing. Any verbal agreements, in particular on cancellation of the 
    written form, are ineffective. EACH PARTY IS ENTITLED TO AFFIX ANY 
    AGREEMENTS ON AMENDMENTS OR SUPPLEMENTS REGARDING THIS LEASE TO THIS DEED.

6.  If any provisions of this contract prove to be or become legally 
    ineffective, the validity of the other provisions of this Lease shall 
    remain unaffected. The contracting parties, however, agree to ensure that 
    the ineffective provisions are replaced by other, economically equivalent, 
    effective provisions, if possible.

7.  The following appendices form part of this contract:

     the calculation of area attached to this contract, Appendix 2.

3.   The floor plan of the leased areas and the required fittings will be set

     requests on part of lessee, lessee has to be provided with a quotation,
     including a statement of a possible delay with respect to the handing over

                                  DURATION OF LEASE

1.   The lease commences on January 2nd, 1998. The lease is contracted for a
     duration of 10 years. It is renewed for another 2 years, unless it is
     terminated at least 6 months before end of the term of lease by one of the
     contracting parties. The notice of termination of the lease must be given
     in writing.

2.   Lessee is entitled to start with the installation of operational equipment
     before the stipulated date. It is obligated, however, to integrate the
     works into the schedule of the building site. The leased premises are
     regarded as complete particularly even if remaining structural work and
     removal of defects are still to be attended to, provided that these works
     and defects will only insignificantly affect the use. In case of a delay in
     handing over, lessee shall not be entitled to terminate this contract or to
     withdraw from this contract unless the handing over of the leased property
     is not effected until February 28th, 1998 at the latest.

     In case of termination of the lease due to rent arrears, rent shall include
     incidental expenses as well.

     building (according to Section 1, Appendix 1), for which an advance payment
     according to Section 4, sub-paragraph 3, has to be made.  Incidental
     expenses shall include all current costs incurred by lessor due to
     ownership of the premises, grounds and fittings, including areas used by
     the public.  These costs are the following:

     Insurance, water charges, canal dues, fees for refuse collection, land tax,
     energy consumption in the general areas, chimney sweeping, street cleaning,
     cleaning of building and facade, attention to grounds and green areas on
     the whole of the premises, snow removal and gritting in icy weather,
     janitor as well as costs of property management (3.5% of the total annual
     gross rent), operation of passenger and goods elevators (firemen's
     elevators) including complete maintenance and, if available, maintenance of
     elevator emergency call device, interior decorative repairs in the general
     areas, cost of maintenance, repair, upkeep, reconditioning, operation and
     checking of the technical equipment (like for instance the heating system,
     lifting facilities, fire alarm, access control facilities, facilities for
     protection against the sun, ventilation and air conditioning equipment,
     emergency power generating unit, supply meters etc.), maintenance of roof's
     covering with greenery and of the waterproof sheetings as well as checking,
     refilling and replacement of hand fire extinguishers.

     If costs for heating, air conditioning or hot-water are determined
     separately by intermediate meters for the area leased by lessee, lessee
     shall bear these individually determinable consumption-based costs.  If
     that is not the case, the accruing expenditure on consumption will be
     distributed at 33 per cent according to the size of the leased area and at
     70% according to consumption determined by measuring facilities.

     If water consumption is determined separately, lessee shall bear 100% of
     the individual consumption costs.  This applies to canal dues accordingly.

     Not later than Sept. 30th of the subsequent year, lessor is obligated to
     settle accounts with lessee on the incidental costs accrued during one year
     of management (Jan. 1st to Dec. 31st), taking into account the advance
     payments made according to Section 4, sub-paragraph 3.

     Additional or short payments have to be mutually compensated immediately.
     In the case of an increase or decrease in operating expenses, lessor shall
     reassess the monthly advance payment correspondingly.

2.   If the increase or the new introduction of operating expenses agreed by the
     two parties causes lessor an additional financial burden, lessee is
     obligated to pay the respective additional amount on a pro rata basis as
     from receipt of a corresponding notification.

3.   Lessor shall be entitled to alter the distribution code and the accounting
     period in its fair judgment.

4.   Registration with the competent public utilities shall be effected by
     lessee in due time before commencement of lease.

                                      SECTION 6
                      CENTRAL HEATING AND HOT-WATER CONSUMPTION

1.   Lessor is obligated to maintain operation of the central heating during
     usual business hours if the outdoor temperature so requires, at least,
     however, in the time from October 1st to April 30th.  Ventilation and air
     conditioning equipment - if available - are to be operated all the year
     round.

2.   Hot-water supply, if not effected by the central heating, has to be
     provided at any time during usual business hours.

3.   A fuel shortage beyond lessor's control, resulting in partial or complete
     suspension of heating, does not entitle lessee to claim reduction or to
     claim for damages.  This also applies to the inevitable interruption of
     operation of the heating facilities due to repair or maintenance purposes.


                                      SECTION 7
                           ALTERATION OF THE AMOUNT OF RENT

1.   The amount of rent remains unchanged during the first year after
     commencement of lease.

     After that date, the agreed amount of rent will change as soon as the
     cost-of-living index determined by the Federal Statistical Office
     (Statistisches Bundesamt) for a worker's family of 4 earning an average
     income, assessed in the base year 1985 at 100 points, has increased or
     decreased as compared with the corresponding level at commencement of
     lease.  In this case, the agreed amount of rent will be changed according
     to the extent of change occurred.  The altered amount of rent, determined
     as described above, will be valid, in turn, for another period of at least
     12 months.  If then the above mentioned index will have increased or
     decreased as compared to the last change of rent, the amount of rent will
     be adjusted for a subsequent period of at least 12 months.  The change of
     the amount of rent is subject to a written request by the party entitled.
     The altered amount of rent is due for payment on the 3rd business day of
     the month following the receipt of the request.

2.   In order to become effective, this agreement requires the approval by the
     Land central bank (Landeszentralbank), to be obtained by lessor.  In case
     of refusal of this approval, however, the provisions agreed by the parties
     shall remain valid.  In this case, the parties will change the index clause
     that way, that it will be approved and will be economically as similar to
     the original clause as possible.

                                      SECTION 8
                                   PAYMENT OF RENT

1.   Rent, advance payment of incidental expenses and value added tax have to be
     transferred, post-free and charges paid, monthly in advance, on the 2nd
     business day of each month at the latest to lessor's account no. 
     11 00 58 195, Bank Code Number BLZ 550 500 00, Landesbank Rheinland-Pfalz 
     in Mainz.

2.   Delay in payment entitles lessor to charge dunning costs of DM 15.00 per
     reminder, incl. VAT plus postage and default interest of 2% p.a. above the
     current discount rate of the Central Bank of Germany (Deutsche Bundesbank).

3.   If lessee effects part payments on the accounts payable, lessor may set
     these payments at its own option against the unsettled accounts, not paying
     consideration to declarations made by lessee.


                                      SECTION 9
                                  SET-OFF, RETENTION

1.   Lessee may claim the reduction of the amount of rent only with prior
     written notification to lessor.

     A set-off and retention by the two parties is possible only if undisputed
     claims or claims raised with final and binding effect are concerned.

2.   A retention and set-off due to claims arising from other obligations is
     excluded.  Claims for compensation according to Section 538 of the Civil
     Code (BGB) are excluded, unless lessor has acted intentionally or with
     gross negligence.


                                      SECTION 10
                             SUBLETTING TO THIRD PARTIES

1.   Lessee is not entitled to subletting or subleasing the premises to third
     parties without prior written consent given by lessor.  Lessor may only
     refuse its consent if there are objective material reasons against such
     subleasing.  Subleasing to companies or subsidiaries of the same group is
     exempt from this provision (Section 2, subparagraph 1 applies accordingly
     to a possible sublessee).

2.   In case of subleasing or subletting, lessee shall be liable for all acts or
     failures by sublessee or that party, to whom it has sublet the use of the
     leased premises.

                                                                         PAGE 7

                                   SECTION 11
                         PLAQUES, ADVERTISING EQUIPMENT

1.   Lessee is entitled to fix a company plaque at the main entrance. The 
     lessor will indicate the position of the advertising equipment, its 
     possible dimensions as well as the possible design according to the 
     planned design of the exterior and considering the official guidelines.

2.   Upon termination of lease, lessee is obligated to remove plaques and 
     advertising equipment as well as the damages caused by fixing, operation 
     and removal.


                                   SECTION 12
                              USE OF THE ELEVATORS

1.   Existing elevators will be in operation 24 hours a day.

2.   In case of operational failures lessee is not entitled to uninterrupted 
     service. A control of the elevators is not provided. Failures have to be 
     communicated immediately to lessor or its representative.


                                   SECTION 13
                         ELECTRICITY, GAS, WATER, HEATING FUEL

1.   Existing electricity (incl. possibly existing telecom and antennae 
     cabling) networks as well as gas and water pipe networks may only be 
     used by lessee to such an extent, that no overstressing will occur. An 
     increased demand may be met by Lessee by extending supply pipes or lines 
     at its own expense after prior written consent of lessor. The laying of 
     any additional pipe or line network within the building is subject to 
     lessor's prior written consent.

2.   In case of failures or damages of the supply network, lessee shall 
     provide for immediate cutoff and inform lessor. In case of imminent 
     danger, lessee is obligated to eliminate this imminent danger at once by 
     itself. Further repair of the damage shall be arranged for by lessor, 
     unless according to this contract the maintenance and repair are 
     incumbent on lessee. If the latter is not the case, lessor shall also 
     bear the cost incurred due to elimination of the imminent danger.

3.   An alteration of the energy supply, in particular a change of the 
     current voltage, does not entitle lessee to assert claim for damages 
     against lessor. In such a case, however, lessee is entitled to 
     exceptional termination of contract.


<PAGE>

                                                                         PAGE 8

4.   If power, gas or water supply or drainage is interrupted by 
     circumstances beyond lessor's control, if irregularities occur with 
     respect to supply or in case of floods or other catastrophes, lessee 
     shall have no right to claim reduction of rent or damages against 
     lessor. This applies to heating fuel supply accordingly, as long as it 
     is effected by the public utilities.

     If the terms of delivery stipulated by the public utilities, from which 
     lessor purchases power or water, provide undertakings' liability for 
     interruptions in supply and for irregularities in delivery, lessor 
     hereby assigns any claims it may have against the public utilities to 
     lessee. Additional claims are not asserted by lessee, unless they could 
     be asserted by lessor as well.


                                   SECTION 14
                              OFFICIAL PERMITS AND
                          OPERATING EQUIPMENT OF LESSEE

1.   Lessor does not assume any liability for the fact that the permits 
     granted for the operation known and planned at present and for the 
     equipment required will continue until after the date of handing over 
     of the leased property (Section 3, sub-paragraph 1). Lessor warrants, 
     however, that a commercial use within the scope of lease set forth in 
     Section 2, sub-paragraph 1, is permitted. This applies in particular to 
     licenses as well. Lessee has to bear all the costs required for the 
     creation and maintenance of the preconditions for the operation of its 
     business. This also applies to advertising equipment etc.; obligations 
     imposed by the trade supervision or other authorities with respect to 
     lessee's business have to be complied with at lessee's own expense.

2.   Before installing machines, heavy objects, other plant and equipment in 
     the leased premises, lessee shall ask lessor about the approved limit of 
     load and obtain lessor's written consent. Lessee is liable for damages 
     caused by failure to comply with this provision. If the installation of 
     this plant and equipment has an adverse effect on the building - 
     tremors, cracks, etc. - lessor may withdraw the granted permit if lessee 
     fails to take remedial action in the due course of time to be 
     stipulated. Lessee is liable for all plant and equipment brought in or 
     operated by lessee. If the installation or operation of lessee's plant 
     and equipment results in unreasonable disadvantages or detriments, 
     lessee is obligated to remove them or to discontinue operation unless it 
     can take remedial action.

3.   Obligations within the scope of the building permit, imposed by the 
     construction supervision authorities with respect to lessee's operating 
     equipment, have to be complied with at lessee's own expense.

                                                                          PAGE 9

                                 SECTION 15
                  MAINTENANCE AND REPAIR OF LEASED PROPERTY

1.  Lessee shall provide for sufficient cleaning, ventilation and heating of 
    the leased property and treat the rooms and the plant and equipment therein
    with care and keep it free from pests.

2.  Lessee is liable for any damages of and in the leased property and for 
    damages of the open space belonging to it, as long as these damages are 
    caused by itself, its employees, family members, vicarious agents, 
    sublessees, visitors, suppliers, customers and workmen, acting with gross
    negligence.

3.  Lessee is obligated, in particular, to have interior decorative repairs 
    of the leased premises executed at its own expense (repapering and/or 
    painting of the walls and ceilings, and, as agreed with lessor, painting
    of coated floors, radiators, visible mains, rusts, doors, windows or 
    other parts, unless they have a coated, eloxed, varnished, galvanized or
    similar surface) within reasonable intervals, and to exchange upper floor
    coverings. Lessee shall maintain and repair lighting installations, bell
    systems, thermometers, locks, water cocks, water closet flushing 
    apparatuses, wash-basins and sinks, stoves, gas burning installations, 
    electric appliances, ventilating equipment, water heaters and similar
    technical installations, exclusively used for lessee's supply, including
    the corresponding feeding pipes or lines and sewage pipes.

4.  Lessee shall inform lessor immediately about any damage occurred with 
    respect to the leased property. Lessee is liable for consequential damages
    caused by delayed notification.

5.  Lessor is not liable for damages suffered by lessee or third parties with
    respect to stored goods and fittings, irrespective of nature, origin, 
    duration or scope of influence, unless lessor has caused the damage 
    intentionally or by gross negligence. In other respects, lessor's 
    liability is limited to the coverage and the scope of the liability 
    insurance, unless lessor has caused the damage intentionally or by gross
    negligence. The amount covered by the houseowner's liability insurance 
    amounts to DM 1,000,000.00 for property damage and pecuniary loss and to
    DM 2,000,000.00 for bodily injury.

                                 SECTION 16
             ALTERATION OF AND IN THE LEASED PROPERTY BY LESSEE

1.  Alterations of and in the leased property, in particular structural 
    alterations, built-ins, installations and the like, are subject to 
    lessor's prior written consent. It is lessee's sole responsibility
    to obtain all the official permits required as well as to comply with
    all the laws and regulations enacted in this respect. Lessor shall,
    however, be of assistance - as far as possible - in obtaining contingent
    official permits.

<PAGE>

                                                                         PAGE 10

    Lessee shall bear all the respective costs and the costs for structural 
    alterations. On lessor's demand, lessee is obligated to remove the 
    structural alterations or built-ins partly or in full when moving and
    to restore the former condition without requiring a reservation on the
    part of lessor when giving its consent. Lessee is liable for any damages
    occurring in connection with the structural alterations performed by 
    lessee.

2.  If on termination of lease lessee intends to remove the installations it
    has fitted to the leased property, it may offer these to be taken over
    by lessor. In doing so, lessee shall make a price proposal, proving 
    production costs and day of manufacture. If lessor wishes to take over
    the fittings, lessee has to be reasonably compensated. If lessor rejects
    the fittings, lessee is obligated to restore the original condition of the
    leased property.

                                 SECTION 17
                    STRUCTURAL ALTERATIONS AND REPAIRS
                                  BY LESSOR

1.  Lessor may executed repair work and structural alterations, which may 
    become necessary for maintenance or economic exploitation of the property
    or for enlargement of the building or for the elimination of damages, 
    without prior consent of lessee. This also applies to works and structural
    measures, which are not strictly necessary but suitable, and will serve,
    in particular, to modernize the building. Lessee shall provide access to 
    the rooms to be considered and must not hinder or delay the execution of
    the works. Otherwise lessee shall compensate for damages caused by such 
    hindrance or delay. In the cases set forth above, lessee is not entitled
    to claim reduction of rent unless insufficient consideration is taken of
    lessee's interests, thus causing detriments to lessee.

                                 SECTION 18
                       ADMITTANCE TO LEASED PROPERTY

1.  During normal business hours, lessee shall ensure, that surveyors and
    interested parties authorized by lessor may view and have access to the
    leased property for the purpose of determination of the state of repair,
    state of the building site, releasing, sale etc., after the visit having
    been announced in due course of time. In case of emergency, the access has
    to be possible at all hours of the day and night.

                                 SECTION 19
                         DUTY TO SAFEGUARD TRAFFIC

1.  Lessee is subject to the duty to safeguard traffic within its area of
    lease, according to the legal provisions. In this respect, lessee 
    releases lessor from third party claims.

<PAGE>
                                                                         PAGE 11

                                 SECTION 20
                                  INSURANCE

1.  Fire insurance, insurance against damages caused by tap water, storm and
    tempest and EC, property liability insurance, fire liability and glass
    insurance of the building are within lessor's responsibility. The 
    insurance premiums incurring in this respect have to be paid by lessee
    as a part of the incidental costs.

2.  Insurance of the objects, goods and built-ins as well as advertising
    and operational equipment brought in by lessee is within lessee's 
    responsibility. Lessee is obligated to effect and maintain a business 
    liability insurance and a leased property damage insurance and to prove
    on request the existence of insurance coverage to lessor.

                                 SECTION 21
                           TERMINATION OF LEASE/
                          EXCEPTIONAL TERMINATION

1.  On termination of lease, lessee shall return the leased property to 
    lessor in a state of expert redecoration (walls and ceilings repainted).
    If floor coverings show signs of wear and tear to an extend exceeding
    wear and tear caused by usual use, lessee shall have the coverings 
    replaced by a specialized company. If lessee fails to comply with this
    obligation, lessor may have the leased property redecorated at lessee's
    expense.

    Lessee's obligation of vacation of premises covers all objects situated
    within the area of the leased property unless they are owned by lessor. If
    lessee fails to comply with its obligation of vacation, lessor is entitled
    to have the vacation executed at lessee's expense. There is no obligation
    on part of lessor to preserve such objects still within the area of the
    leased property after termination of lease.

2.  Lessor may immediately terminate the lease for material reasons, if:

    a)  lessee is in arrears with its rent payments or with other financial
    obligations amounting to a month's rent for more than a month;

    b)  lessee continues the use of the leased property in breach of contract
    or the unauthorized subletting to a third party despite admonition by 
    lessor;

    c)  a petition has been filed for institution of composition proceedings
    or in bankruptcy with respect to lessee's assets or if lessee has made an 
    affirmation in lieu of an oath according to Section 807 of the Code of 
    Civil Procedure (ZPO) or if lessee discontinues payments;

    d)  lessee fails to comply with its essential contractual obligations 
    within a reasonable period of time despite written admonition by lessor;

<PAGE>

                                                                         PAGE 12

    Lessee is entitled to a corresponding right of termination, if lessor 
    fails to comply with its obligations according to subparagraph 2 c/d above.

3.  In case of termination of lease without notice, lessee is liable for any 
    loss of rent until termination of the agreed period of lease, which is 
    caused by the leased property not being rented or by the fact that in 
    case of a new lease the previous amount of rent cannot be achieved. 
    Lessor is obligated to do everything possible in order to find a new 
    lessee to take over the leased property. Lessor will accept a new lessee
    provided by lessee, under the condition that the new lessee is comparable
    to lessee in terms of kind and scope of operating business and with regard
    to financial soundness.

4.  On termination of lease, lessee shall hand over all the keys, including 
    those it has had made, to lessor.

                                 SECTION 22
                               OTHER AGREEMENTS

1.  Lessor is entitled to transfer any rights and obligations on the part of 
    lessor under this contract to third parties with the effect of discharging
    debts, without lessee being in a position to derive any rights of any
    nature from this fact.

2.  Refuse originated by lessee's business activities, except office refuse, 
    may not be disposed of in the dustbins provided by lessor for general use,
    but has to be disposed of by lessee itself.

                                 SECTION 23
                           PROVISION OF SECURITY

1.  In order to secure lessor's claims under this agreement, lessee is 
    obligated to provide a promise of surety by an important German bank
    or Sparkasse (savings bank) amounting to 12 gross monthly rents incl.
    incidental costs, immediately after signing of contract or to submit
    a letter of support of its American parent company.

                                 SECTION 24
                   EFFECTIVENESS OF PROVISIONS OF CONTRACT

1.  Later modifications and supplements to this contract must be made in 
    writing. It cannot be contracted out verbally. If any of the provisions
    of this contract becomes legally invalid, be it partly or in full, the
    validity of the other provisions shall remain unaffected. In such a case,
    the contract has to be fulfilled correspondingly.
    If the invalidity is caused by a determination of performance or time, it 
    will be replaced by the performance or time permitted by statute.

                                   SECTION 1

                                LEASED PROPERTY

1.   Lessor grants Lessee a lease of office and hall/ service areas (BGF) 
     including outside areas as well as 9 outside parking spaces (Leased
     Property) located in the Airport Center, building part L (Langenhomer
     Chaussee 42).

     General areas, as for instance foyer and elevator anterooms, are 
     proportionately included in the lease.

     Airport Center and the Leased Property are known to Lessee.

2.   Location, size and design of the Leased Property can be taken from the 
     Planning Documents attached, signed by the two parties 
     [plan no. 1, 2 and 3 (Appendix 5)], and from the Building Specification 
     (Appendix 4), both of which form part of this lease. The leased building 
     areas are to be considered as agreed and are marked in red outline, the 
     leased parking spaces and outside areas are marked in green outline.

3.   Lessor reserves the right to alter the overall planning of the Airport 
     Center.


                                   SECTION 2

                 USE OF LEASED PROPERTY, NON-COMPETITIVE CLAUSE

1.   a.   Lessee shall make use of Leased Property only as offices, service 
          areas or for storing as well as for the operation of line-based 
          telecommunication systems according to the Business Description 
          (Appendix 3) forming part of this lease. The outside areas may not 
          be used for storing purposes.

          Deliveries of storage material through the entrance area is 
          possible only for products, the size and type of which is 
          reasonable for an office operation.

          A change of use is subject to Lessor's prior written consent. 
          Consent may not be withhold, unless the change of use has negative 
          consequences for Lessor, be it economic or other. Possible 
          declarations of consent are made - even if not explicitly stated - 
          subject to the required official permits.

<PAGE>

          Any expenses caused by particular requirements, activities or 
          products on the part of Lessee (e.g. easily flammable products, 
          materials hazardous to ground water, operation of service, 
          exhibitions, trainings, air-conditioning etc.) and by the 
          respective installations or the resulting obligations imposed by 
          authorities, trade associations or by insurance companies, are 
          to be borne by Lessee.

          Lessee shall procure the permits required for its business and 
          shall comply with possible obligations and conditions.

     b.   On the part of Lessee, no hazardous materials (e.g. explosives, 
          toxicants) may be stored or processed and no activities may be 
          performed implying an aggravation of the insured risks or 
          contradicting official permits, as for instance provisions of the 
          zoning plan.

          No objects whatsoever may be stored and no works may be performed 
          on part of Lessee outside the Leased Property, i.e. in and on the 
          commonly used rooms and areas - including those leased 
          proportionately - and in the leased delivery area. Vehicles of 
          Lessee, its visitors and its employees may only be parked within 
          designated spaces. Other vehicles may only stay temporarily on the 
          premises for the time required for loading and unloading. According 
          to official requirements, escape routes are to be kept clear.

          On the occasion of any bigger events (e.g. training courses), 
          lessee is obligated to expressly point out to its visitors that 
          they may park their cars only in the leased parking lots or 
          outside the Airport Center. On Lessee's failure to comply with this 
          provision, Lessor may claim from lessee a reasonable compensation 
          without prejudice to its other rights.

2.   Lessee shall inform Lessor immediately in writing of each and every 
     change with regard to Lessee which is of importance in connection with 
     this Lease (in particular change of legal structure, business license, 
     transfer of the company's domicile).

3.   Lessee shall use the sanitary facilities on the first floor together 
     with the other lessees.



<PAGE>

4.  Lessee is entitled to share the use of the elevator. Lessee is obligated 
    to comply with the elevator regulations in all points. In case of an 
    operational breakdown, Lessee shall not have the right to claim
    uninterrupted service. A control of the elevator is not provided.

5.  Lessor does not grant Lessee any protection against competition with 
    respect to Lessee's area of business.

6.  Lessee knows that no gas-driven vehicles may be parked on interior parking
    lots lease be Lessee.



                                       SECTION 3

                                   DURATION OF LEASE

1.  The Lease begins on January 1st, 1998 (Beginning of Lease). It is 
    contracted for a duration of 10 years. The period of lease will end on 
    December 31st, 2007.

    After termination of the agreed duration of lease, the Lease is renewed 
    for another 2 years, unless terminated by one of the contracting parties 
    observing a notice period of one year.

    Section 568 BGB (Civil Code) is not applicable.

2.  Leased Property is handed over to Lessee ready for occupation. Ready for 
    occupation means to the two parties, that the leased property is completed 
    according to the planning documents and the building specification, so 
    that occupation and contractual use by the lessee according to Section 2, 
    sub-paragraph 1 of this contract is possible. Defects or remaining 
    structural work, including construction of the exterior grounds, which do 
    not essentially hinder occupation and use are not contradictory to the 
    completion of readiness for occupation as defined by this Lease.

    On the day of completion of readiness for occupation, the Leased Property
    is handed over to lessee for use. The parties draw up a take-over 
    protocol, determining possible defects of the leased property with binding 
    force and covering remaining structural work. Lessor shall remedy or 
    execute these without delay according to a defined schedule. Lessee shall
    allow work designed to remedy defects during its business hours as 
    well.

    Prospectively, Lessor shall have the leased object ready for occupation 
    by lessee, except for remaining work on exterior grounds due to bad 
    weather, by January 1st, 1998 (date of completion of readiness for 
    occupation).




<PAGE>



    Lessee shall submit its schedule for the finishing works not later than 
    November 15th, 1997. Any delays due to special finishing work on 
    Lessee's request or delayed information to Lessor are on Lessee's expense.

    In the case of delays in completion of readiness for occupation caused by 
    requests for alteration made by Lessee after signing this contract of
    lease, the Lease and liability to pay rent, will begin on the day, on 
    which the handing over could have taken place without the request for 
    alteration.

    Delays in completion of readiness for occupation, in particular due to 
    strikes, lock-out, war, force majeure, fire and to days of bad weather 
    as approved by the Arbeitsamt (government employment office), are not 
    within Lessor's liability.


                                     SECTION 4

                        AMOUNT OF RENT AND INCIDENTAL EXPENSES

1.  The flat-rate amount of rent per month for the leased object is DM 
    20,288.24 (IN WORDS: TWENTY THOUSAND TWO HUNDRED AND EIGHTY-EIGHT 24/100TH 
    DEUTSCHE MARK) plus advance on the incidental expenses and respective 
    statutory value added tax (at present 15%), in the following referred to 
    as gross rent.

    The rent for the month of May 1997 is reduced by DM 1,441,20 (IN WORDS: 
    ONE THOUSAND FOUR HUNDRED AND FORTY-ONE 20/100TH DEUTSCHE MARK).

    Lessee represents and warrants to be entitled to complete input tax 
    deduction. In the case of a change of this circumstance, causing the 
    elimination of the preconditions for Lessor's turnover tax option under 
    Section 9 sub-paragraph 2 of the Turnover Tax Law UStG, Lessor is no 
    longer bound to list the turnover tax separately, with the consequence 
    that the previous gross rent is paid as monthly flat-rate amount of rent 
    in future. If the absence of the precondition for the option becomes 
    known later, Lessor shall be entitled to rectify the invoices made out 
    so far in such a way that the contractual gross rent paid so far 
    subsequently corresponds to the monthly flat-rate rent. In the case of 
    absence of the precondition for option, compensation is reserved. On 
    Lessor's demand, Lessee is obligated to submit a corresponding 
    confirmation given by Lessee's tax adviser.

    Payment of gross rent is to be effected, post and expenses paid, on an 
    account to  be indicated by Lessor, not later than the 3rd work day of 
    each month.

<PAGE>


   With respect to punctuality of payment, receipt of payment by Lessor is 
   decisive. On delay in payment, default interest of 4% above the respective 
   discount rate of the Deutsche Bundesbank as well as dunning costs to the 
   extent of DM 10.00 are agreed. The assertion of further damages caused by 
   delay is reserved. 
   
   Lessee shall grant Lessor a direct debit authorization for the gross rent 
   corresponding to Appendix 2 to this contract of lease, not later than one 
   month before beginning of lease.
   
2. Rent and value added tax are to be paid from May 1st, 1998. Incidental 
   expenses and value added tax are to be paid from date of completion of 
   readiness for occupation according to Section 3, sub-paragraph 2 of this 
   contract.

3. The accruing incidental expenses are to be paid separately by Lessee. In 
   detail, the following shall apply in this respect:

   a. Subject to official regulations, domestic waste collection is 
      effected by Lessor and apportioned with the incidental expenses to 
      the individual lessees. All other kinds of garbage disposal are 
      effected by Lessee subject to statutory provisions, each and every 
      accruing garbage collection fee being paid by Lessee directly to the 
      corresponding authority. In the case that Lessee effects the garbage 
      disposal itself, Lessee undertakes to use only closed containers for 
      garbage disposal. In case a change of official regulations, Lessor 
      reserves the right to handle domestic refuse collection like the 
      above mentioned types of garbage.

   b. Lessee pays fees and costs of its consumption of gas, long-distance 
      energy and other energy consumption as well as counter fees and 
      installation costs directly to the energy supplier.

   c. Lessee pays fees and costs of its consumption of gas, 
      long-distance energy, water and hot water as well as counter fees and 
      installation costs.

      Operation costs of the central heating system are distributed 
      according to the regulation on heating expenses, with 70% of the 
      costs being apportioned based on consumption.

   d. If applicable, Lessee shall bear the proportionate operating and 
      maintenance costs with respect to the overall property, in particular 
      for:

<PAGE>

      General power, exterior lighting, lighting of underground car park, 
      parking lot and multistory car park; garbage disposal; canal dues; 
      cleaning of street, footpath, multistory car park, underground car 
      park, parking lot and facade as well as cleaning and maintenance of 
      the other made up exterior areas, including snow and ice removal; 
      cleaning of sanitary facilities, foyer, stairwell and windows as well 
      as cleaning of the commonly used toilets and their repair; 
      elimination of pests; chimney-sweep; janitor; property tax; 
      maintenance and repair (including examinations by TUV) of sanitary 
      and heating facilities, of air-conditioning and electric facilities, 
      of windows, doors, and gates, of drainage lifting facilities 
      (including storm water reservoir), of the multistory car park, 
      underground car park, barrier and parking routing facilities, of smoke 
      alarms and emergency power generating units, of transformers, 
      lighting guard, of elevators, emergency call facilities, of the fire 
      alarm unit, of the sprinkler system, of the barrier and video system, 
      the code card system, safety lighting, of the roof, of smoke and 
      warmth outlet systems, of hydrants and fire extinguishers, of blinds, 
      of water heating systems and hot-water supply systems, building 
      insurance (covering fire, storm and tempest, damages caused by water 
      from the main, extended coverage, glass in general areas) and 
      building and houseowner's liability insurance; upkeep, maintenance, 
      and design of green areas, hydrocultures, and of the commonly used 
      areas of building, street and exterior; safeguarding of traffic, 
      security service; doorman's service; property administration (the 
      latter amounting to 4% of the rent, even if administration is 
      effected by Lessor). Proportionate repairs exceeding the amount of 
      10% of the annual gross rent (Section 4, sub-paragraph 1) per 
      calendar year are not to be borne by Lessee.
      
   e. If the fees and expenses listed under c. and d. are directly 
      assignable to Lessee, they will be allocated this way. If not, Lessee 
      will be charged on a pro-rata basis. Lessee's share of the rented 
      areas of the whole building or of the respective part of the building 
      shall be taken as the key to distribution of proportionate expenses. 
      Key to distribution of costs with respect to multistory car park or 
      to underground car park shall be Lessee's share of leased parking 
      spaces in the multistory car park or underground car park. Lessee's 
      share of the general areas shall be taken as the key to distribution 
      of costs with regard to general areas leased on a pro-rata basis. 
      Lessor may change the key to distribution at its reasonably exercised 
      discretion, if this will lead to a more objective cost allocation.
      
      Lessor is entitled to demand monthly prepayment of all prospective 
      incidental expenses, provided they are not to be paid by Lessee 
      directly. Settlement of accounts for the calendar year is effected 
      once a year. On termination of lease during an accounting period, 
      settlement of accounts is not effected in the meantime but within the 
      scope of the general settlement of accounts. On this occasion, 
      prepayments for incidental expenses are set off.

<PAGE>

          Possible compensation payments are to be effected on
          the date of rent payment following the settlement of
          accounts.  Vouchers concerning the respective
          settlement of accounts of incidental expenses may be
          inspected by Lessee in Lessor's offices during usual
          working hours within six weeks after sending off the
          statement of accounts of incidental expenses.

          Lessor reserves the right to review the monthly
          prepayment of incidental expenses on a regular basis
          and, if necessary, to increase them due to a
          substantiated increase in costs and to demand single
          prepayments for higher amounts of incidental expenses,
          payable at the following rent payment date.  For the
          time being, prepayment of incidental expenses to be
          paid by Lessee from handing over date on, is fixed at
          DM 3,327.80 (IN WORDS:  THREE THOUSAND THREE HUNDRED
          AND TWENTY-SEVEN 80/100TH DEUTSCHE MARK) per month plus
          statutory value added tax (at present 15%).

          If public fees whatsoever or any other incidental
          expenses in connection with Lessee's business or with
          the leased property become due after signing this
          contract of lease, Lessor shall be entitled to demand
          corresponding payments from Lessee from handing over
          date on.

4.   With respect to claims for rent or incidental expenses, no
     rights of setoff, rent reduction nor rights of retention
     can be claimed unless Lessee's claim is undisputed or has
     become res judicata.

5.   Lessee shall not exercise a possible right of setoff, rent
     reduction or retention because of an undisputed or res
     judicata counterdemand, unless Lessee has announced such
     intention to Lessor in writing not later than one month
     before the next rent payment concerned is due.

6.   If Lessee fails to pay the rent, the incidental expenses
     and/or the value added tax on time, possible payments will
     be set off against claims soon coming under the statute of
     limitations, then against the rent and other debts as for
     instance costs and interests.


<PAGE>


                           SECTION 5

                        VALUE GUARANTEE

1.   The rent according to Section 4, sub-paragraph 1, shall
     increase or decrease corresponding to changes of the overall
     cost-of-living index after expiry of 12 months after
     beginning of lease.  The monthly price index for the cost of
     living of all private households in Germany as determined by
     the Statistisches Bundesamt (Federal Statistical Office) in
     Wiesbaden is authoritative.  The parties agree on the
     overall cost-of-living index in the month of signing the
     contract as figure of reference on the basis of 1991 = 100.

2.   If the above value guarantee gives rise to a change of rent,
     the clause will become applicable again after expiry of 12
     months according to the provision of the previous paragraph,
     and the rent will be adjusted correspondingly.

3.   The parties know that this value guarantee is to be approved
     by the competent Land central bank.  Approval is to be
     obtained by Lessor.

     If the Land central bank denies its approval, the parties
     are bound to look for another solution as close as possible
     to the purpose intended and permitted by statute.

4.   If the cost-of-living index 1991 = 100 can no longer be
     determined, a transition by conversion to the basis of the
     next published cost-of-living index should be effected.  In
     other respects, the above procedure remains unchanged.  This
     applies to each and every later conversion of the
     cost-of-living index to another base year.

                           SECTION 6

                           INSURANCE

1.   The usual building insurance (covering fire, storm and
     tempest, damages caused by water from the main, extended
     coverage, glass in general areas) and building and
     houseowner's liability insurance are effected by Lessor at
     Lessee's expense.


<PAGE>


2.   Installations, finishing works or rebuilding of the Leased
     Property by Lessee, exceeding those stated in the Planning
     Documents and the Building Specification, are not covered by
     the building insurance, unless notified to Lessor by Lessee
     in writing before beginning of the respective installations,
     finishing works or rebuilding, requesting an increase of
     insurance coverage.  The expenses of such installations,
     finishing works or rebuildings have to be proved by Lessee
     by presenting corresponding invoices.  Lessor is entitled to
     consult a surveyor at free choice in order to determine the
     value of the corresponding installations, extensions or
     rebuildings.  All the costs involved are borne by the two
     parties at equal shares.  The additional insurance for the
     respective installations, finishing works or rebuildings of
     the Leased Property by the building and houseowner's
     liability insurance is not given until Lessor has received
     the respective written confirmation of cover by the
     corresponding insurance company.  The cost of additional
     insurance shall be borne by Lessee.

     Lessor has not effected a vehicle and luggage insurance for
     the cars parked in the Airport Center.

3.   For the period of lease, Lessee is bound to effect and
     maintain at its own expense each and every insurance
     necessary and common for its business, like for instance a
     manufacturer's liability insurance, a burglary and
     housebreaking insurance  and, if the Leased Property is not
     used for office purposes only, an environmental liability
     insurance.  It is, furthermore, within Lessee's
     responsibility to ensure sufficient insurance coverage
     against damages of fittings and other objects brought in.

     Lessor is entitled to demand a corresponding written
     confirmation by the insurance company as a proof that these
     insurances are duly effected and maintained.

4.   It is pointed out to Lessee that it may include the
     insurance of indemnity obligations against Lessor into its
     manufacturer's liability insurance.

                           SECTION 7

               STRUCTURAL DESIGN AND ALTERATIONS

1.   The Leased Property is built according to the Planning
     Documents attached. Lessor reserves the right to perform
     structural alterations of the Leased Property subject to
     official or statutory conditions for the purpose of
     improvement, for reasons of an economic time schedule or
     construction, as well as to deviate from the Planning
     Documents and Building Specification not causing a decrease
     in value.
<PAGE>

     Lessor shall notify Lessee, if the Leased Property is essentially affected
     by these measures.


2.   Lessee's requests for alterations regarding finishing works and design of
     the Leased Property put forward during construction are taken into
     consideration by Lessor only, if these requests do not result in essential,
     in particular structural modifications of the Leased Property and do not
     cause the building costs to be higher than estimated.

     As far as Lessee's requests for alterations result in higher building costs
     or prolong the construction time, Lessor will essentially consent to these
     requests for alterations, if the type of the Leased Property remains
     basically unchanged by the alterations and if Lessee bears the additional
     costs, including but not limited to any loss of rent caused by the delay in
     construction with a time limit, previously to be agreed by the contracting
     parties.

     If Lessee's requests for alterations cause any additional costs in
     connection with planning and engineering, these shall be borne by Lessee.


3.   Lessee is entitled to decorate the interior of the Leased Property at its
     own expense and according to its own needs. Essential structural
     modifications, however, are subject to Lessor's prior written consent. The
     required official permits are to be procured, if possible, directly by
     Lessee; in any case, the costs of planning and permits are to be borne by
     Lessee.


4.   During the Period of Lease, Lessee is entitled to effect structural
     modifications of the Leased Property, which it considers to be necessary,
     at its own expense, unless these modifications require changes of statics,
     affect wires or pipes of the building or essentially change the character
     of the Leased Property. The implementation of such alterations is subject
     to Lessor's prior written consent which is to be obtained by submitting
     plans. Lessor will grant its consent, provided the alterations will not
     have any adverse effects, economic or other, on the leased property.

     Lessee shall bear all the costs accrued by the structural alterations
     effected by Lessee and the respective maintenance and repair, including but
     not limited to costs for permits and auditing plans, which have to be sent
     to Lessor immediately on completion of such works. Lessee indemnifies
     Lessor from all conceivable liabilities in connection with the structural
     alterations.

<PAGE>

     This shall include, that Lessee indemnifies Lessor for the loss of possible
     warranties against defects with regard to the building workers involved.

     It is possible, that structural alterations are subject to an official
     permit for change of use. Any costs in connection with the change of use,
     regardless whether they are caused by the structural alterations or by
     complying with official obligations, are to be borne by Lessee.


5.   Changes to the outer appearance of the Leased Property - in particular to
     the exterior facade, window design, made up exterior and green areas - are
     subject to Lessor's prior written consent which is at Lessor's complete
     discretion. This applies as well to installations in connection with the
     installation of alarm and/or fire alarm systems.


6.   Lessor will mark the parking spaces leased by Lessee on Lessee's expense,
     using signs chose by Lessee.


7.   In front of each entrance Lessor has put up a plate indicating the
     companies. On the spaces destined, Lessee is entitled to attach its company
     name/logo in accordance with Lessor. The cost of labeling is to borne by
     Lessee.

     Exterior advertising on the part of Lessee is not permitted.


8.   In the hall, Lessor shall have a suspended ceiling installed [lowered area
     approx. 500 m(2), type Odenwald-mineral fiber plate ceiling (narrow edge
     3)].


9.   Subject to sub-paragraphs above, Lessee shall be given the opportunity to
     establish line-based connections to alternative suppliers of
     telecommunications infrastructure.


                                      SECTION 8

                     LIABILITIES, MAINTENANCE OF LEASED PROPERTY

1.   It is within Lessee' responsibility to treat the Leased Property with care
     and to maintain its working order. Damages to the Leased Property or
     necessary works within the scope of property management have to be reported
     to Lessor in writing or via telefax immediately after knowledge has been
     obtained.

<PAGE>

2.   It is Lessee's obligation to make the Leased Property safe for persons or
     vehicles and it is reliable for each and every culpable breach of this
     duty. Lessee releases Lessor from all third party claims originated by a
     breach of the obligation to make premises safe for persons or vehicles.

     As from beginning of Lease, Lessee is liable to Lessor for all damages
     culpably caused by members of its business, its visitors and guests, by
     people engaged by Lessee (workmen, deliverymen) as well as by sublessees
     and their auxiliary staff. Lessee is liable, in particular, for such
     damages, which are caused by negligent treatment of water pipes, gas lines,
     electric lighting circuits or power cables, by leaving doors, gates and
     windows open, by insufficient precautions against frost damages or by
     failure to comply with duties incumbent on Lessee according to this
     contract or to official and statutory provisions (lighting, obligation to
     strew sand or salt in case of snow or icy conditions etc.). It is incumbent
     on Lessee to prove that such culpable conduct was not the case.

     Lessee shall inform Lessor immediately about any loss of keys of the lock
     system and shall indemnify Lessor for any damages hereby caused.

     Lessor is not liable for any damages other than those covered by an
     existing building and houseowner's liability insurance, unless in case of
     intention or gross negligence.

     Lessor is not liable for any damages suffered by Lessee in connection with
     the use of or due to defects of the Leased Property, unless caused
     deliberately or with gross negligence on the part of Lessor. Lessee shall
     release Lessor from all third party claims, asserted by third parties
     against Lessor because of defects of the Leased Property, unless caused by
     Lessor deliberately or with gross negligence.


3.   Lessee is obligated to perform interior decorative repairs (for example
     interior painting, wallpaper, floor and floor coverings, inner and other
     doors) every 3 years thus maintaining the Leased Property in a reasonable
     and well looked after condition. Furthermore, Lessee is obligated to
     ensure, at its own expense, that doors, gates, windows, blinds, electric
     and sanitary facilities, locks, fire extinguishers, water taps, wash basins
     and sinks and similar facilities, including feeding lines and drainage, are
     always maintained in working order. Additionally, Lessee is obligated to
     ensure, at its own expense, that broken glass panes, mirrors or other
     objects of glass and defect lighting fixtures of the Leased Property are
     replaced without delay. Lessee is further obligated to always maintain its
     exterior, traffic and park areas in working order.
<PAGE>

     Lessee is also liable for all damages of the leased parking spaces and
     their surroundings, for example soiling of floor and walls by leaking oil,
     soot, or exhaust gases culpably caused by itself, its visitors, guests or
     by individuals engaged by Lessee. Lessee is obligated to have the
     corresponding necessary maintenance work professionally executed.

     For other minor repairs, Lessee shall bear the costs up to DM 500 plus
     statutory value added tax (at present 15%) in each individual case, not
     exceeding, however, an amount according to Section 4, sub-paragraph 3 d.
     The parties agree that for January 1st of each calendar year, this sum will
     be increased for the following year corresponding to the percentage
     increase of the total cost-of-living index according to Section 5,
     sub-paragraph 1, sentence 1 and 2.


4.   It is incumbent on Lessee to keep the Leased Property clean.

     Maintenance of the green areas and cleaning and repair of made up exterior
     areas of the Airport Center are effected by Lessor or its agents. Lessee
     shall ensure that these areas are easily accessible for the execution of
     these works.


5.   Lessee may not claim damages or reduction of rent because of a defect of
     the Leased Property or because of a breakdown of the operation of the
     building or its technical facilities, unless Lessor is provably responsible
     for the defect as a consequence of intentional or gross negligent conduct.
     This applies to each and every claim of Lessee subject to Section 538,
     sub-paragraph 1 BGB (Civil Code). It is expressly referred to Lessee's
     liability to effect an insurance of its fittings brought in according to
     Section 6 of this contract.


6.   Lessee is aware of the fact that the Airport center described in the
     Preliminary Statement is used by other lessees as well. If necessary, house
     regulations determining the limits of rights and obligations of individual
     lessees will be agreed together with the other lessees and then become part
     of this contract.


7.   Lessor may perform structural works which become necessary for the
     development, maintenance or improvement of the real estate or the Leased
     Property or for averting imminent dangers or for elimination of defects,
     even without Lessee's consent.

     Repairs and structural alterations of the Leased Property, which are not
     necessary but appropriate, may be performed with Lessee's consent, if these
     works only marginally interfere with Lessee.


<PAGE>

8.   When installing heavy equipment (machines etc.), Lessee shall ask Lessor
     about the carrying capacity of the floors. It has to satisfy itself
     regularly and carefully that the floors' carrying capacity according to
     Building Specification is not exceeded. On failure to comply with this
     provision, Lessee is liable for all damages and consequential damages
     hereby caused and is obligated to release Lessor from all possible third
     party claims arising from this disregard.


9.   Reduction of rent and damage claims on the part of Lessee based on
     immissions or obstructions of the accesses to the building beyond Lessor's
     control or on works according to sub-paragraph 7 above or on construction
     work performed by third parties outside the building, are excluded.


                                      SECTION 9

                        ENTERING OF LEASED PROPERTY BY LESSOR

1.   After prior arrangement, Lessor or its agent may enter the Leased Property
     during business hours in order to determine the necessity of possible
     mending or to execute repair and maintenance work. On the occasion of such
     inspections or works, Lessee is entitled to send an accompanying person
     along. Lessee already now declares its consent to possibly necessary works
     on feeding lines on part of the other lessees of the whole property. This
     consent also applies to the case that other lessees have to effect works on
     the feeding lines.

     In cases of imminent danger, Lessor may enter or force an entry into the
     Leased Property at all hours of the day and night.

     Access to skylight, service facilities and inner courtyards are to be
     provided at any time.


2.   If Lessor intends to sell the real estate, Lessor may enter the Leased
     property at usual times after arrangement with Lessee. On Sundays and
     public holidays, however, this shall require Lessee's express
     authorization.


3.   On termination of Lease, or if the existing Lease is not renewed 12 months
     before expiration of Lease at the latest, the previous paragraph shall
     apply to the entering of the Leased Property by Lessor with a new
     prospective lessee.


<PAGE>

                                      SECTION 10

                                 TERMINATION OF LEASE

1.   On termination of Lease, the Leased Property is to be returned in an
     expertly renovated and repaired condition and together with all the keys.
     This obligation shall be in force irrespective of the fact whether or not a
     periodical renovation would have been due.

     If Lessee fails to effect the incumbent renovation works until the end of
     Lease, Lessor may commission the execution of the work on Lessee's expense
     after having once granted a grace period. In this case, Lessee shall be
     liable for any damages suffered by Lessor because of the delayed execution
     of the work (in particular loss of rent).

2.   Facilities (e.g. controlling equipment, communication facilities, alarm
     systems etc.), including advertising facilities installed by Lessee, may or
     - on Lessor's request - must be removed.

     If Lessee takes the fittings with it, it shall restore the former state at
     its own expense, if so required by Lessor.

     Lessee will have the suspended ceiling in the hall, which had been
     installed on its request, expertly removed at its own expense.


3.   In the case that Lessee has performed structural alterations, Lessor may,
     at its option, demand either the restoration of the original state free of
     charge or reimbursement of the costs accrued by such restoration. Lessee's
     compensation for expenses caused by structural alterations is excluded at
     any rate, regardless whether or not Lessor demands restoration of the
     original condition. If structural alterations are not removed, these shall
     pass into Lessor's ownership without requiring an indemnification nor a
     compensation to be paid to Lessee.


4.   On termination of Lease, the objects installed by Lessor remain within the
     Leased Property.


5.   A return of the Leased Property prior to termination of Lease is subject to
     Lessor's express prior written consent.

<PAGE>

                                  SECTION 11

                              SECURITY FOR RENT

1.  Not later than 2 weeks prior to the handing over of the Leased Property, 
    Lessee is obligated to procure the absolute bank suretyship of a big 
    German, American or Japanese bank resident in Germany corresponding to 
    Appendix 1 to this Lease, amounting to three month's rents plus advance 
    payments of incidental expenses and the respective statutory value added 
    tax (at present 15 %) plus an amount of DM 375,000 plus statutory value 
    added tax (at present 15 %), covering each and every financial obligation 
    on part of Lessee subject to this contract. If finishing works on 
    Lessee's demand are to be effected by Lessor, the suretyship is to be 
    submitted prior to placing the order for the finishing works. Lessor 
    shall inform Lessee about the date of placing the order.

    The guarantor is obligated to pay upon Lessor's first demand. Guarantor 
    waives its right to defense of the surety, due to Lessee and guarantor 
    under the law, in particular defenses of defeasibility, of offset, and of 
    failure to pursue remedies (Sections 768, 770, 771 BGB, Civil Code), and 
    the possibility of depositing. Lessor is entitled, but not obligated, to 
    satisfy its claims with the suretyship.

2.  In the case that the suretyship is not provided within the period 
    stipulated, the Leased Property will not be handed over. Lessee is 
    responsible for any delays due to such circumstance; Lessee is not 
    released from the obligation to pay rent according to Section 4, 
    sub-paragraph 1.

    On delay in procuring the suretyship on part of Lessee, Lessor may demand 
    that instead of the suretyship, Lessee has to procure a security of the 
    same amount in cash which Lessor is not to pay interest on.

3.  If Lessor makes use of the suretyship, Lessee shall be obligated to 
    replenish the suretyship upon Lessor's first demand.

<PAGE>

4.  In the case of changes with respect to rent, monthly prepayment for 
    incidental expenses or to the statutory value added tax, suretyship is to 
    be adjusted to the change on Lessor's demand within one month after the 
    corresponding effective date.

5.  The obligation of suretyship terminates on Lessor's return of the surety 
    bond to guarantor. This return is to be effected as soon as each and 
    every financial obligation of Lessee with respect to the Lease are 
    fulfilled after termination of Lease.

6.  With respect to the security in cash (Section 11, sub-paragraph 2, 
    sentence 3), the previous provisions as to the suretyship shall apply 
    accordingly.

                                   SECTION 12

                                   SUBLEASING

1.  Lessee may sublease the Leased Property, in full or in part, subject to 
    Lessor's prior written consent and provided that sublessee uses the 
    Leased Property within the scope of this contract of lease - in 
    particular with regard to Section 2, sub-paragraph 1 - and that sublessee 
    assumes all obligations resulting from this contract. On subleasing, 
    Lessee remains responsible to the full extent, including but not limited 
    to the payment of rent.

    Lessor points out that it will deny its consent to subleasing or 
    permission of use of lease by third parties, unless the third party 
    commits itself to use the Leased Property, which is subject-matter of its 
    contract with Lessee, exclusively for sales allowing input tax deduction. 
    In other respects, Lessor will refuse its consent to subleasing for 
    substantial reasons only.

    If Lessee realizes a higher amount of rent than agreed with Lessor, the 
    excess amount is due to Lessor. Partial areas within the hall (technical 
    areas) are expressly exempt from this provision.

    On denied consent, Lessee has no right of termination according to Section 
    549, sub-paragraph 1 BGB (Civil Code).

2.  Lessee already now assigns its claims against sublessee with regard to 
    rent payments to Lessor, granting Lessor the right to demand direct 
    payment of subrent to Lessor.

<PAGE>

                                   SECTION 13

                        RIGHT OF EXCEPTIONAL TERMINATION

Lessor shall have the right to terminate the lease with immediate effect 
without observing a period of notice, if

a.  Lessee has been in delay with rent payment or a considerable  part of the 
    rent payment for two subsequent payment dates,

    or if Lessee is in delay with rent payments to the extent of an amount 
    corresponding to two month's rent payments for a period of time covering 
    more than two dates;

b.  Lessee or sublessee use the Leased Property in breach of contract or 
    permit the use of Leased Property to third parties without authorization 
    despite written caution by Lessor;

c.  an administrator is appointed to realize and distribute Lessee's assets 
    or composition proceedings are instituted or on dismissal of a petition 
    in bankruptcy for lack of assets;

d.  Lessee considerably molests the other lessees despite written caution;

e.  Lessee is not granted the official permits necessary for its business or 
    if these official permits are withdrawn. Notice of termination may not be 
    given until Lessee has received three cautions and continues its conduct 
    in breach of contract.

If Lessee is responsible for the reason for the termination, Lessee shall be 
liable against Lessor for the total damage caused by the termination, 
including in particular, but not limited to, loss of rent, of incidental 
expenses and of value added tax.

Section 19, sentence 2 KO (Chandler Act) remains unaffected. For the duration 
of this liability, Lessee has to release Lessor from all third party claims 
originating from termination according to Section 13. In this case, Lessor is 
obligated to take up leasing activities without delay and to examine 
appropriate subsequent lessees.

                                   SECTION 14

                                  FINAL CLAUSES

1.  In the case of the Leased Property being sold, Lessor's liability 
    according to Section 571, sub-paragraph 2 BGB (Civil Code) is excluded.

<PAGE>

2.  The contract on hand and the Appendices 1 to 6 contain all provisions 
    agreed. Modifications and amendments to this contract must be made in 
    writing. This also applies to the annulment of the written form itself. 
    No verbal supplements have been agreed.

    If a present or future provision of this contract is or becomes 
    ineffective, inoperative or unpracticable, the validity of the other 
    provisions of this contract remain unaffected. The same applies, if a gap 
    to be filled becomes evident after signing this contract.

    The parties shall replace the inefficient or void provision or gap to be 
    filled by an efficient provision, corresponding to the legal and economic 
    content of the inefficient or void provision and to the overall purpose 
    of this contract.

                                   SECTION 15

                             PLACE OF JURISDICTION

                                LEASED PROPERTY

1.   Lessor is owner of the premises at 80807 MUNCHEN, LEOPOLDSTRASSE 236, 
     'PALLAS HAUS'(1), hereinafter also referred to as 'Property'

2.   Lessor grants Lessee a lease of the following areas ('Leased Area') and 
     parking spaces(2), hereinafter collectively referred to as 'Leased 
     Property', the location of which can be taken from the plan attached as

                                  APPENDIX 1:

     2.1   Office area on the 1st FLOOR                  approx. 1,152.81 m(2)
     2.2   Proportionate general area                    approx.          m(2)
     2.3   Archives area on                              approx.          m(2)
     2.4   Storage area                                  approx.          m(2)
     2.5   Service area                                  approx.          m(2)
     2.6   Parking spaces in the underground car park/
           in the multi-story car park                                 6 units
     2.7   Parking spaces outside                                        units
     2.8
     2.9
     2.10

3.   The size of the above mentioned Leased Area is agreed ACCORDING TO DIN 
     277 BGF.

4.   A possible deviation of the size of the Leased Area indicated in 
     sub-paragraph 2. from the actual conditions by up to 1.5% (one and a half 
     per cent) of the total of the Leased Area mentioned in sub-paragraph 2. 
     does entitle neither Lessor nor Lessee to change the amount of rent. 
     In the case of a deviation of more than 1.5%, the amount of rent shall 
     be adjusted according to the full deviation. After expiry of one year 
     after handing over of the Leased Property, neither Lessor nor Lessee may 
     demand such adjustment of rent.

                                    SECTION 2

                HANDING OVER OF LEASED PROPERTY AND PURPOSE OF LEASE

1.   The Leased Property shall be handed over to Lessee at the beginning of 
     Lease. On this occasion, a joint handing over protocol shall be prepared 
     to include possible defects and remaining works, which have to be 
     immediately remedied or executed by Lessor.

     By signing this handing over protocol, Lessor acknowledges the condition 
     of the Leased Property as contractually agreed, except for hidden 
     defects, unless any defects/remaining works are mentioned in the 
     handing over protocol.

2.   On the occasion of taking over, Lessee shall receive a set of keys and a 
     code-card for each parking space in the underground car park. Any 
     additional keys or code-cards required by Lessee will be provided 
     immediately at Lessee's expense.

3.   Any company signs in the central entrance area are designed and 
     installed on the same lines. To the extent permitted by the necessary 
     uniform design, Lessor will take into account any requests expressed by 
     Lessee. This shall apply correspondingly to a possible routing system. 
     Costs of such uniform company signs and of a possible routing system and 
     the corresponding installation shall be borne by Lessor. Costs of 
     modifications and special requests are to be borne by Lessee.

4.   For the duration of Lease, Lessee shall and will run an OFFICE in the 
     Leased Property. Each change of business/occupation exercised in the 
     Leased Property is subject to Lessor's prior written consent. It is 
     within Lessee's sole responsibility to ensure that the Leased Property 
     is economically suited for the use hereunder agreed.

5.   LESSOR HAS OPTED FOR THE VALUE ADDED TAX FOR THE PROPERTY ACCORDING TO 
     SECTION 9, SUB-PARAGRAPH 2 OF THE TURNOVER TAX LAW (UStG).(3) LESSEE 
     WILL USE THE LEASED PROPERTY EXCLUSIVELY FOR TURNOVERS WHICH ARE SUBJECT 
     TO INPUT TAX DEDUCTION. IF LESSEE USES THE PROPERTY FOR TURNOVERS 
     EXCLUDING INPUT TAX DEDUCTION IN BREACH OF THE ABOVE PROVISION, LESSEE 
     SHALL INFORM LESSOR IMMEDIATELY. IN THIS CASE, LESSEE IS BOUND TO 
     COMPENSATE LESSOR FOR ANY DISADVANTAGES CAUSED BY THE LOSS OF INPUT TAX 
     DEDUCTION. ADDITIONALLY, LESSEE WILL PROVIDE LESSOR WITH A WRITTEN 
     DECLARATION CONFIRMING THAT LESSEE WILL USE THE LEASED PROPERTY ONLY FOR 
     TURNOVERS WHICH WILL NOT EXCLUDE INPUT TAX DEDUCTION. IN THE CASE OF 
     THAT LESSOR MUST PROVIDE THE FINANCE AUTHORITIES WITH MORE EXTENSIVE 
     EVIDENCE IN THIS RESPECT, LESSEE SHALL BE OBLIGATED TO SUBMIT LESSOR THE 
     CORRESPONDING DOCUMENTATION OR TO SUBMIT SUCH DOCUMENTATION DIRECTLY 
     TO THE FINANCE AUTHORITIES, IF THIS IS SUFFICIENT TO COMPLY WITH LESSOR'S 
     OBLIGATIONS.



- ------------------------
(3) According to Section 9, sub-paragraph 2 Turnover Tax Law UStG, this 
    option is allowed for the lease and demise of premises only, if Lessee 
    uses or intends to use the premise for turnover only which do not 
    exclude input tax deduction.


<PAGE>

6.   Any orders or conditions imposed by the authorities, which are 
     exclusively based on the overall nature and/or the location of the 
     Property, have to be complied with by Lessor. If any conditions imposed 
     by the authorities or the procurement/maintenance of official permits 
     are EXCLUSIVELY based on personal or particular operational 
     circumstances with regard to Lessee or on particular circumstances of 
     Lessee's business enterprise, the measures and costs hereto connected 
     shall be borne exclusively by Lessee. In this respect, Lessee has also 
     to comply at its own expense with any future orders or conditions by the 
     authorities with regard to the use of the Leased Property, even if such 
     orders or conditions are directed against Lessor.

7.   It is left to Lessor's sole discretion to lease other areas within the 
     Property to third parties pursuing the same purpose of lease as Lessee 
     as put forth in sub-paragraph 4. Lessee is not granted any protection 
     from competition.

                                SECTION 3

                     BEGINNING AND DURATION OF LEASE

1.   The Lease shall begin on the day of handing over the Leased Property. 
     Handing over will prospectively take place on February 2nd, 1998. Lessor 
     shall communicate in writing the expected week of handing over two 
     months and the exact day of handing over two weeks prior to the handing 
     over date. Lessor shall take over the Leased Property on this 
     communicated date. The dates resulting from the above may be postponed 
     due to strike and/or force majeure. [If and to that extent Lessor is 
     provided with material required for the completion of the Leased 
     Property (e.g. parting walls, doors) by third parties, the dates 
     resulting from the above are subject to complete, correct and timely 
     supply, unless non-supply or delay is caused by Lessor's negligence.]

2.   If the handing over date resulting from subparagraph 1. is delayed by 
     more than 2 months, Lessee may withdraw from contract. Any other claims 
     whatsoever on the part of Lessee are excluded, unless Lessor has acted 
     willfully or negligently.

3.   THE LEASE IS CONTRACTED FOR THE DURATION OF TEN YEARS, FROM THE FIRST 
     DAY OF THE MONTH FOLLOWING THE HANDING OVER DATE.
     One year prior to expiry of the fixed duration of lease at the latest, 
     not earlier, however, than after expiry of eight years of lease, Lessee 
     may demand in writing the opening of negotiations with respect to the 
     renewal of the Lease by up to ten years, renegotiating rent payments and 
     terms of contract. The rent to be renegotiated shall correspond to the 
     rent which can be realized at the location of the Property at the 
     beginning of the last year of the fixed period of lease, at least, 
     however, to the rent due for the last year of Lease according to Section 
     5.

<PAGE>

     If the contracting parties cannot come to an agreement on the new rent 
     payment and on the new terms of contract of lease by signing a new and 
     legally valid contract of lease within the first three months of the 
     last year of Lease, this Lease will terminate on expiry of the last year 
     of Lease without requiring a notice of termination.

4.   If Lessee does not demand the opening of negotiations with respect to a 
     renewal of this Lease according to sub-paragraph 3 above, the Lease 
     shall continue for an unlimited period of time, unless terminated by one 
     of the contracting parties not later than nine months prior to 
     termination of the fixed period of lease. If the Lease continues for an 
     unlimited period, it is subject to termination with a notice period of 9 
     months for the end of a month.

5.   When the Lessee remains in possession of the Leased Property after 
     expiry of the Lease, the Lease is not to be regarded as renewed. Section 
     568 German Civil Code BGB is contracted out.

6.   In the case of the complete destruction or the destruction of a major 
     part of the Leased Property by an event beyond Lessor's control (e.g. 
     fire etc.), Lessor shall inform Lessee immediately about the plans and 
     the expected duration of the reconstruction, if Lessor decides on 
     reconstruction.

                             SECTION 4

                       CANCELLATION OF LEASE

1.   Each cancellation of Lease must be made in writing. Receipt of the 
     written notice of cancellation and not its dispatch date is 
     authoritative for the timeliness of cancellation.

2.   Lessor and Lessee may terminate the Lease upon good cause without due 
     notice. Lessor may further terminate the Lease without due notice, if 
     and when

2.1. Lessee has been in delay with rent payment or a considerable part of the 
     rent payment for two subsequent payment dates (Section 554, sub-section 
     (1), sub-paragraph 1 German Civil Code BGB, or

2.2. Lessee is in delay with rent payments to the extent of an amount 
     corresponding to two month's rent payments for a period of time covering 
     more than two dates (Section 554, sub-section (1), sub-paragraph 2 
     German Civil Code BGB), or

2.3. Lessee has filed a petition in bankruptcy or for institution of 
     composition proceedings with regard to its assets, if it must make a 
     written verification pursuant to Section 807 Federal Rules of Civil 
     Procedure ZPO, if extrajudicial proceedings for the payment of debts 
     have been instituted or if Lessee has suspended payments, or

<PAGE>

2.4  composition or bankruptcy proceedings with regard to Lessee's 
     assets have been instituted or if the commencement of such 
     proceedings is rejected for lack of assets or for other 
     reasons, Lessee is responsible for,

2.5  Lessee is in delay with the provision of the security and if this 
     security for rent is not provided within a grace period of two weeks.

</TABLE>

2.   Lessee's obligation to pay the amount of rent stipulated in sub-paragraph 
     1. shall begin as of beginning of Lease according to Section 3. 
     This applies as well, if Lessee stays away from handing over of Leased
     Property despite timely information about the handing over date by Lessor
     or if the handing over does not take place because of failure to provide
     the security for rent.

<PAGE>


3.   The partial amounts agreed under Section 5, sub-paragraph 1.1 to 
     1.10 and the flat charge agreed according to Section 10, 
     sub-paragraph 2 of this Lease are subject to value guaranty as follows:

3.1.     Effective beginning of the 13th month from beginning of Lease on 
         (beginning of the second year of Lease), the partial amounts as per
         sub-paragraph 1.1 to 1.10 and the flat charge according to 
         sub-paragraph 1.14 shall be adjusted corresponding to the change
         of the cost of living index of all private households in Germany
         (all-German index; base year 1991 = 100) as compared with the index
         level in the month of beginning of Lease (Base Month).

3.2.     Then, the sums mentioned in sub-paragraph 3.1 shall be adjusted for 
         every following year of Lease corresponding to the change of index, 
         comparing the value taken as a basis for the last adjustment with the 
         index of the last month of the expired year of Lease. Each adjustment
         shall be effective from the first month of the new year of Lease on.

3.3.     The above mentioned adjustments are effected automatically, so that 
         the amount adjusted to the change of index is due without special 
         demand from beginning of the new year of Lease. Unless Lessee has
         received a recalculation in writing from Lessor, effects of delay in
         payment (Section 6, sub-paragraph 2) cannot originate.

4.   The contracting parties agree that this index clause is subject to the 
     approval by the Land central bank in order to be valid. The approval 
     shall be obtained by Lessor. If the index clause is not approved by the 
     Land central bank, the contracting parties undertake to come to an 
     arrangement that can be approved and which is as similar as possible to 
     the terms agreed in this contract.

5.   If an index clause as per sub-paragraph 3.1 and 3.2 cannot be 
     approved of (e.g. because of the duration), the partial amounts as per 
     sub-paragraph 1.1 to 1.10 and the flat charge as per sub-paragraph 1.14 
     shall be adjusted according to the following procedure: if the index  
     mentioned in sub-paragraph 3.1 changes as compared with the index of 
     the base month, both the contracting parties agree to negotiate on an 
     adjustment of the partial amounts as per sub-paragraph 1.1 to 1.10 and 
     of the flat charge as per sub-paragraph 1.14 after expiry of the first 
     year of lease. This adjustment shall become effective beginning of the 
     second year of lease. If the parties do not reach an agreement with 
     respect to the adjustment within two months, the decision shall be taken 
     by an arbitrator, who shall be appointed by the local competent Chamber 
     of Industry and Commerce on application filed by one party. Arbitrator 
     may only be a person who is an executive of a regionally or 
     internationally lending Realtor enterprise. The arbitrator shall adjust 
     the partial amounts as per sub-paragraph 1.1 to 1.10 and the flat charge 
     as per sub-paragraph 1.14 taking into account the above mentioned index 
     development, considering also the rents then agreed for commercial 
     buildings comparable to the Leased Property. The parties, however, agree 
     that a reduction of the partial amounts as per sub-

     
<PAGE>

     paragraph 1.1 to 1.10 and of the flat charge as per sub-paragraph 1.14 
     can be demanded only, if the changed index is lower than the value of 
     the base index, even if an arbitrator's expert opinion in on hand. The 
     above provision applies to the following years of Lease 
     correspondingly. The costs of the expert opinion are shared. In the 
     case of a lawsuit, however, the court order as to costs shall apply to 
     the costs of the expert opinion as well.

                                 SECTION 6

                      PAYMENT OF RENT - SECURITY FOR RENT

1.   Payment of rent is to be effected monthly in advance, post and expenses 
     paid, on Lessor's account No. 00 1009 6060 with DG BANK Deutsche 
     Genossenschaftsbank, Hamburg (bank identification number BLZ 200 600 
     00) indicating lessee identification number, by the 3rd working day of 
     each month at the latest. Crediting of the money and not its dispatch is 
     decisive for punctuality.

2.   In the case of delay in payment on the part of Lessee, Lessor is 
     entitled to charge penal interest to the extent of 5% (five per cent) 
     p.a. above the discount rate of the Deutsche Bundesbank, unless Lessor 
     can prove a loss of a higher degree or Lessee can prove a loss of a 
     lower degree in the individual case. Lessor's right of termination 
     according to Section 4 remains unaffected.

3.   Not later than FOUR WEEKS PRIOR TO HANDING OVER, Lessee shall 
     provide a security for rent

     3.1  by bank guaranty of a German bank or savings bank according to
                                  APPENDIX 2
          to the amount of treble monthly rent (Section 5, sub-paragraph 1.17), 
          that is of

                                DM 140,286.00
          (IN WORDS: DEUTSCHEMARKS ONE HUNDRED AND FORTY THOUSAND TWO HUNDRED 
          AND EIGHTY-SIX)

          waiving defense of defeasibility and of setoff and of failure to 
          pursue remedies.

     3.2  deleted

4.   In the case the Property being sold, Lessor is entitled and 
     obligated to transfer the security for rent to the buyer.

5.   Landlord's lien is subject to legal provisions.

                                   SECTION 7

                           INCIDENTAL EXPENSES

1.   The advance payment for incidental expenses agreed in Section 5, 
     sub-paragraph 1.12 is effected to cover the incidental expenses of the 
     Property described hereinafter. As advance payment of the incidental 
     expenses shown below, Lessee pays monthly in advance

                               DM 5,187.65

     (IN WORDS: DEUTSCHEMARKS FIVE THOUSAND ONE HUNDRED AND EIGHTY-SEVEN 
     65/100) plus statutory value added tax.

2.   In terms of this Lease, incidental expenses are any taxes, 
     contributions, fees and expenses incurred or accrued by Lessor due to 
     ownership/lease in perpetuity of the Property and/or due to the agreed 
     use of property, building or economic unit (the latter includes 
     adjoining buildings, multi-story car parks/underground car parks, plants 
     and facilities), in particular costs of:

2.1       the total of the current public taxes, property tax, 
          domestic waste disposal, collection of recycling materials, 
          chimney-sweeping, canal dues, water-supply, sewage and drainage 
          (including rainwater/surface water) and the corresponding metering

          cleaning of all exterior grounds and playgrounds, green areas and 
          gardens including replacement or supply of plants and trees;

2.3       cleaning of the building including common areas, rooms and 
          facilities, entrance halls, elevators, stairwells and of the other 
          commonly used parts of the building, cleaning and maintenance of the 
          outer glass surfaces and facades (except display windows and entrance 
          facilities) and of pest control;

2.4       operation and lighting of the common areas and rooms as well as of 
          common facilities and grounds, entrance halls, elevators, 
          stairwells, parking lots, multi-story car parks/underground car 
          parks, as well as of other commonly used parts of the building 
          including replacement of defect bulbs and lamps and costs of 
          regular safety checks;

<PAGE>

2.5       operation and maintenance of the common technical equipment 
          and facilities (in particular routing facilities of the building, 
          elevators and hoists including emergency call facilities in elevators 
          and their rent, escalators, fire alarm system, CO2 alarm system, 
          sprinkler systems, butterfly dampers and smoke funnels, air 
          conditioning equipment, aerators, outer grounds fit for traffic, 
          gasoline separators, lifting facilities, pressure intensifiers etc.) 
          including each and every measuring system and the respective rent and 
          calibration, use of common communication systems (e.g. large-band 
          cable);

2.6       insurance(4) against fire, storm and tempest, water damage, 
          (including EC-coverage) and against loss of rent suffered by Lessor, 
          liability insurance as well as costs of safety checks required by 
          insurance contract;

2.7       janitor or of other janitor services as well as guards and 
          doorman;

2.8       any other expenses subject to apportionment as operating costs as 
          per Appendix 3 of Section 27, sub-paragraph 1 of the II, order as 
          to charges(5) as amended at the time when the costs are incurred.

2.9       property management and care-taking (both management by third 
          parties and self-management) at a flat charge of 3.5% (THREE POINT 
          FIVE per cent) of the partial amount agreed under Section 5, 
          sub-paragraph 1.1 to 1.10.

3.   If new incidental expenses according to sub-paragraph 2. incur or 
     if incidental expenses increase, Lessor may apportion these expenses to 
     the lessees of the Leased Property from the date of the 
     accrual/increase on and Lessor may fix reasonable advance payments. 
     Unless Lessor disposes of current assessment notices as to property 
     tax, these shall be replaced by calculations of the expected property 
     tax burden.

4.   If the above mentioned incidental expenses are apportioned to the 
     lessees of the Leased Property, the criteria for apportionment and the 
     accounting period are fixed by Lessor in its fair judgment, taking into 
     account the principle of equal treatment of all the lessees and 
     considering imperative provisions of the law. In doubt, accounting of 
     incidental expenses is effected according to the share of the 
     respective leased area in relation to the total of the leased area in 
     the Property.

5.   Notwithstanding the above provision, Lessor is entitled - to the 
     extent technically possible - to demand from Lessee a direct settlement 
     of individual incidental expenses (e.g. water consumption) with the 
     respective supplier or to allocate costs corresponding to the 
     individual use of services by the lessees of the Property. Lessee is 
     obligated to provide access to supply meters and other measuring 
     facilities at any time.

6.   The proper disposal of refuse not subject to domestic waste collection 
     (in particular hazardous waste and hazardous materials as well as bulky 
     refuse like packing material etc.) is incumbent on Lessee. The temporary 
     proper storage of such refuse until their collection is also incumbent 
     on Lessee. Lessor, however, shall endeavor to help with this according 
     to local possibilities. Garbage skips may only be put up in areas 
     especially earmarked by Lessor. Outside these areas, neither refuse nor 
     materials destined for recycling may be stored.

7.   Lessor shall settle accounts of advance payments effected by Lessee once 
     a year, not requiring supporting documents on the cost of management 
     flat charge agreed in sub-paragraph 2.9. A possible difference between 
     advance payment and account in favor of Lessor/Lessee is to be settled 
     by Lessee/Lessor within one month after receipt of settlement of 
     accounts. In the case of Lessee's moving during an accounting period, 
     apportionment is effected with the following settlement of accounts in 
     relation of leasing period to accounting period, when in doubt. On 
     expiry of one year as from the day of receipt of the settlement of 
     accounts, objections to accuracy are excluded.

8.   If Lessor furnishes proofs of the fact that the monthly advance payment 
     is insufficient for coverage of the incidental expenses, Lessor may adjust 
     the advance payment accordingly, also during a running accounting 
     period. If the settlement of accounts issued by Lessor shows a reduction 
     of the incidental expenses, the advance payments for the following 
     accounting period shall be reduced accordingly.


                                   SECTION 8

                               HEATING EXPENSES

1.   The advance payment of the heating expenses agreed in Section 5, 
     sub-paragraph 1.13 is effected for the heating expenses described 
     hereinafter. As advance payment of the heating expenses shown below, 
     Lessee pays monthly in advance.

                                    DM 1,152.81
       (IN WORDS: DEUTSCHEMARKS ONE THOUSAND ONE HUNDRED AND FIFTY-TWO 81/109)
     plus statutory value added tax.

2.   In terms of this contract of Lease, heating expenses are in particular 
     costs of fuel and its delivery, operating current, operation, 
     maintenance, control, and attending of heating plant, combustion 
     chamber, and of the flue gas system, costs or regular readiness and 
     reliability check with regard to service including control by an expert, 
     cleaning of plants and of operational premises, metering according to 
     the federal protective law on emissions (Bundesemissionsschutzgesetz), 
     lease or other kinds of transferal for use of equipment for measuring 
     consumption as well as the costs of use of an equipment for measuring 
     consumption and its calibration including the costs of calculation and 
     allocation. In the case of long-distance energy, the total of the costs 
     of heating supply and the costs of operation of the corresponding 
     in-house plants and the above mentioned costs are part of the heating 
     expenses.


<PAGE>

3.   To the extent that Lessor provides the Leased Property with hot water 
     for sanitary purposes, the costs of the hot water supply system shall 
     form part of the heating expenses. Sub-paragraph 2, sentence 2 applies 
     to long-distance hot water correspondingly.

4.   Every year, accounts are settled with respect to the advance payments in 
     compliance with the regulation on heating expenses (Heizkostenverordnung). 
     In the case of long-distance energy supply, the proportionate consumption 
     of the energy obtained is determined by means of sub-meters, calibrated 
     according to statutory provisions. In other respects, the provisions of 
     Section 7 shall apply accordingly.

                                   SECTION 9

    BREAKDOWN OF THE HEATING PLANT, OF TECHNICAL EQUIPMENT, AND OF SUPPLY

1.   In the case of technical breakdowns, force majeure, official directives 
     or other complete or partial impossibility if performance, heating of 
     the Property and/or operation of technical equipment cannot be claimed. 
     Local fuel shortage is to be regarded as force majeure.

     Lessor is obligated to arrange for the measures necessary and reasonable 
     in order to remedy the failure. Lessee's right to claim reduction of 
     rent in the case of a not only temporary breakdown of the heating of the 
     Leased Property and/or of the operation of technical equipment remains 
     unaffected.

2.   Lessor is obligated to operate the central heating system, if the 
     weather so requires, at least, however in the time from October 1st to 
     April 30th.


                                   SECTION 10

              MAINTENANCE AND USE OF PROPERTY AND OF LEASED PROPERTY

1.   Lessor shall assume the maintenance of the exterior of the Property and 
     shall bear the respective costs.

2.   Additionally, Lessor shall assume

2.1       the maintenance and repair of the common areas, the common 
          technical facilities and plants outside the Leased Property and 
          replacement of broken outer windows;

2.2       the remedy of damages to the building and/or grounds caused by 
          third parties like for example visitors or customers of Lessee;



   
<PAGE>

2.3       the purchase (including deduction for depreciation) of 
          equipment used for cleaning, snow and ice removal and for the 
          maintenance of grounds and building including multi-story car 
          park/underground car park as well as for maintenance and cleaning 
          of all the exterior grounds like green areas and gardens.
    
2.4       Maintenance, repair and upkeep of bell system, intercom and buzzers.

          For a lump sum payment for costs connected with these measures 
          incurred by Lessor, Lessee shall pay monthly DM 0.20/m-squared, 
          irrespective of the amounts actually incurred. This payment shall 
          be adjusted to the respective change of the cost-of-living index 
          according to Section 5, sub-paragraph 3 of this Lease plus 
          statutory value added tax.

    Any damage claims on the part of Lessor against Lessee resulting from 
    statutory or contractual provisions regarding liability remain 
    unaffected by the above provision.

3. Maintenance, repair and upkeep within the Leased property are within 
   Lessee's responsibility and have to be effected at Lessee's expense. 
   Among these are in particular maintenance, repair and upkeep of 
   electric power plants, light installations, and electric bell systems, 
   sanitation, gas boilers and suchlike, kitchen utensils, mountings, 
   locks, windows (inside), sunshades (inside and outside), internal 
   partitionings, air conditioning equipment and ventilation systems 
   (provided situated within the Leased Property). Lighting fixtures and 
   bulbs and tubes within the Leased Property are to be replaced by Lessee 
   at its own expense. Regular check, maintenance and replacement of fire 
   extinguishers within the Leased Property, even of those provided by 
   Lessor, is incumbent on Lessee.

4. Display windows and entrance facilities are to be cleaned by Lessee 
   at regular intervals.

5. Interior decorative repairs within the Leased Property are to be 
   executed by Lessee at regular intervals.

6. Prior to the installation or modification of technical plants which 
   may molest third parties or endanger grounds or building due to their 
   operation (e.g. concussion, noise, odor, vibration, contaminants, 
   radiation, dust, gases, parasitic current), Lessee shall inquire about 
   the relevant provisions (including those of trade associations) and 
   standards and obtain Lessor's written consent presenting the 
   aforementioned information. Lessee is entitled to be granted such 
   consent, provided any adverse effects on third parties, grounds or 
   building are excluded. If such technical plants, however, cause any 
   nuisance to third parties or adverse effects on grounds or building, 
   Lessor may withdraw the previously granted consent and demand removal 
   of such plants. If such plants cause any damages to grounds and/or 
   building, Lessee shall pay damages. This also applies to the 
   installation of heavy apparatuses, machines, safes, and suchlike in the 
   Leased Property with respect to the inherent dangers.

<PAGE>

7.  If Lessee handles materials which may be detrimental to health or 
    environment (e.g. toxic, unhealthy, fiery, inflammable, explosive, 
    irritant, corrosive, carcinogenic substances or materials hazardous to 
    ground water), Lessee is obligated to comply with all the relevant 
    regulations as to handling of these dangerous materials and to release 
    Lessor from any risks  and official obligations connected hereto. 
    Lessor is entitled to demand from Lessee to effect and maintain a 
    reasonable liability insurance covering any risk involved by the 
    handling of such substances. On demand, Lessee shall prove the 
    conclusion of such an insurance contract, the insured sum, and the 
    continuance of coverage to Lessor at any time. Lessee shall indemnify 
    for any loss caused by the use of hazardous materials (including 
    preservation/storage) attributable to Lessee.
    
8. Any damages to grounds or building are to be reported to Lessor or 
    its representative as soon as noticed by Lessee. In the case of 
    imminent danger, Lessee shall take appropriate action if possible.
    
9. Lessee is responsible to Lessor for any damages caused by its 
    failure to exercise proper care incumbent on Lessee, in particular in 
    the case of improper handling of plants, objects or substances put 
    forth in sub-paragraph 6. and 7.
    
10. Lessee shall immediately remedy any damages it is liable for in 
    accordance with Lessor. If Lessee fails to comply with this provision 
    within a reasonable period of time despite written caution by Lessor, 
    Lessor may have the necessary work executed at Lessee's expense. In the 
    case of imminent danger, a written caution and setting of a time limit 
    is not required.

                                  SECTION 11

                                  SUBLEASING

1.  The complete or partial leaving of the Leased Property to a third 
    party for the purpose agreed in Section 2, sub-paragraph 4, is subject 
    to Lessor's prior written consent. To this end, Lessee shall first 
    submit the contract of subleasing to Lessor. Lessor shall refuse its 
    consent to subleasing for substantial reasons only. Lessor may withdraw 
    a consent previously granted, if the third party's person or conduct 
    justified a termination of Lease without notice if they were the case 
    with Lessee. Denial and withdrawal of Lessor's consent as agreed above 
    do not entitle Lessee to termination of contract.

<PAGE>

2.  By signing the Lease, Lessee assigns its claims against sublessee 
    including lessor's lien to Lessor, in order to provide security for 
    all claims due to Lessor subject to this Lease and Lessor accepts
    such assignment. This applies to subleasing with Lessor's consent
    and to subleasing without Lessor's consent and to each and every other
    permission of use. If Lessee realizes by subleasing a higher amount
    of rent per m(2) than agreed in Section 5, sub-paragraph 1.1 to 1.10, 
    50% (fifty per cent) of the excess amount is due to Lessor, payable
    retroactively each month.

3.  In the case of subleasing or other permission of use, Lessor shall be
    liable for each and every act and omission by sublessee/user irrespective
    of its own negligence, as if it had been its own conduct.

                                 SECTION 12

          INSTALLATION AND STRUCTURAL ALTERATIONS BY LESSEE AND
                  ADVERTISING AND SPECIAL WORKS EQUIPMENT

1.  Any installations and structural alterations of the Leased Property by 
    Lessee including but not limited to installation/modification of built-in
    facilities are subject to Lessor's written consent. Lessee shall submit
    appropriate plans in advance. The above shall apply accordingly to 
    installation/modification of customary advertising equipment, signs and 
    other special works equipment outside the Leased Property. Lessor shall 
    refuse or withdraw its consent for substantial reasons only. Lessor may
    make its consent to such installations outside the Leased Property 
    dependent on payment of a compensation for use. Supplementary it is 
    referred to Section 10, sub-paragraph 10.

2.  Obtaining and maintenance of official permits required for the above
    mentioned measures is incumbent on Lessee. Lessee shall furthermore
    bear all the costs involved in such measures. If technical plants are 
    subject to official approval and/or regular examinations (e.g. by the 
    Technical Control Association TUV), approval and examination are to be 
    arranged by Lessee at Lessee's expense. Lessee shall prove to Lessor the 
    execution of such approval and examination and submit the corresponding 
    results. On termination of Lease, Lessee shall restore the original 
    condition or leave the installations and structural alterations or any other
    facilities to Lessor without claiming indemnification.

<PAGE>

                                 SECTION 13

           REPAIRS AND STRUCTURAL ALTERATIONS PERFORMED BY LESSOR

1.  Subject to timely agreement of a date, Lessor is entitled to make
    repairs or structural alterations which are necessary for the
    maintenance of grounds, building or the economic unit, for averting
    dangers or for elimination of damages, even without Lessee's consent. 
    This shall also apply to works and structural measures which are not
    necessary but appropriate, in particular such works which serve to 
    improve exploitation or to build up the Property (including heightening 
    of the building) including but not limited to structural alterations
    performed in connection with a new lease of single rooms or with the 
    redevelopment of the Property.

2.  Lessor shall pay necessary regard to Lessee's interests when performing
    the works. It shall inform Lessee timely prior to beginning of the works
    and present the plans for the structural alteration/building up. Lessee 
    shall keep the rooms and areas of the Leased Property affected by these 
    measures accessible to a reasonable extent.

3.  Deleted.

4.  Lessee is entitled to rent reduction or to make use of the right of 
    retention, if such works exclude fully or in part the use of the Leased
    Property for the agreed purpose or interfere substantially with the use. 
    Section 541 b sub-paragraph (2) German Civil Code BGB is contracted out.
    Any claims for damages on the part of Lessee are limited in accordance
    with Section 14.

5.  Lessee shall tolerate to a reasonable extent any measures for 
    modernization and improvement within the Leased Property, subject to timely
    agreement of date. Sub-paragraph 1 to 4 shall apply accordingly.

6.  If the necessity arises to provide Lessee temporarily with other areas
    for lease because of the measures described in sub-paragraph 1., the 
    contracting parties will enter into a separate agreement on this subject,
    with Lessor undertaking to bear the moving expenses.

<PAGE>

7.  Lessor is entitled to lease outer facades and roofs of the Property to
    third parties for advertising installations and suchlike, safeguarding
    Lessee's legitimate interests.

                                 SECTION 14

                LIABILITY OF LESSOR - NUISANCE BY THIRD PARTIES

1.  Any claims for damages on the part of Lessee, including any claims, 
    arising from obligations prior to contract and from tort, can only
    be put forward if they are due to:

1.1    intention or gross negligence on the part of Lessor or its vicarious
       agents or
1.2    negligent failure to comply with an essential contractual obligation
       on the part of Lessor or its vicarious agents or
1.3    the lack of a guaranteed feature of the Leased Property.

2.  Lessor is not liable for any disturbance of the use of the Leased Property
    caused by third parties including other lessees of Property. It will, 
    however, endeavor to use its influence to eliminate any disturbances 
    reported to him, safeguarding the interests of the lessees.

3.  Any disturbances of the use of the Leased Property caused by external 
    factors (such as traffic diversions, digging up, roadblocks, annoyance
    caused by noise, bad smell and dust and concussions) shall substantiate
    warranty claims by Lessee only if these factors essentially impair the
    contractual use of the Leased Property and if Lessor is not in a position
    to limit these disturbances to a reasonable extent. Short-term 
    disturbances as described above shall not substantiate any warranty claims 
    on the part of Lessee.

4.  Each and every exclusion of and limitation on liability under this 
    contract is also applicable in favor of Lessor's vicarious agents.

                                 SECTION 15

                                 INSURANCE

1.  At the expense of the incidental expenses as per Section 7, sub-paragraph 
    2.6, Lessor is entitled to insure the building against the risk of fire, 
    storm and tempest, and water damage, (including EC-coverage) and against
    loss of rent(6) suffered by Lessor, and to effect a liability insurance
    to an extent reasonable with regard to the risks involved.

- ---------------
(6) Covers exclusively indemnification for loss of rent in the case of 
destruction of/damage to Leased Property, e.g. by fire, lightening.

<PAGE>

2.   Lessee is obligated to inform Lessor immediately in writing of any
     installations and alterations in and of the Leased property causing a value
     increase and, in particular, of any alteration as of the class of risks
     with regard to the terms of fire and liability insurance.  Possible costs
     of respective extra charges are to be borne by Lessee.

3.   Insurance of objects, technical equipment and installations brought in by
     Lessee against damages of all types is incumbent on Lessee.


                                      SECTION 16

                              ACCESS TO LEASED PROPERTY

     During usual business hours, Lessor and its vicarious agents may enter the
     Leased Property together with interested parties, experts or witnesses for
     the purpose of exercising landlord's statutory lien, examination of the
     structural condition of the Leased Property and of the operativeness and
     safety of technical installations in the Leased Property, for the purpose
     of subletting or sale of the Leased Property, or in similar cases.  Except
     for cases of imminent danger, timely announcement is required.


                                      SECTION 17

                                 TERMINATION OF LEASE

1.   By termination of Lease, Lessee shall remove any damages caused by the use
     and any hazardous substances possibly brought in while using the Leased
     Property and shall effect due interior decorative repairs.  In due time
     prior to termination of Lease, a common protocol shall be prepared, stating
     any damages caused by the use, due interior decorative repairs (including
     of floor coverings) and installations and structural alterations and/or
     other facilities to be removed by Lessee.

2.   If the Leased Property was handed over to Lessee in a renovated condition
     or if Lessor paid Lessee the costs of renovation, Lessee is obligated to
     completely renovate the Leased Property (excluding common areas) - IN
     DEROGATION OF THE PROVISION AGREED IN SUB-PARAGRAPH 1 -.  This obligation
     to renovate shall include in any case the replacement of wallpaper or
     repainting of walls and ceilings and the replacement of carpets and other
     floor coverings subject to wear and tear, using the same quality as
     provided when handing over the Leased Property.  Colors and patterns of
     carpets and wallpaper and of the paints used for walls and ceilings are to
     be agreed with Lessor.  Instead of a renovation effected by Lessee, Lessor
     is entitled to demand from Lessee a redemption of 100% of the costs charged
     for the renovation by an expert firm.  If the contracting parties doe not
     reach an agreement as to the amount of such renovation costs, an expert
     appointed by the local chamber of crafts shall act as an arbitrator in this
     matter.  Costs of the arbitrator are shared between the contracting parties
     at equal moieties.


<PAGE>

3.   On termination of Lease, Lessee shall return the Leased Property, according
     to the terms of this Lease, duly vacated, with all the keys, including any
     additional keys possibly manufactured by Lessee, and with all the code
     cards, by the date agreed with Lessor.  On Lessee's failure to do so
     despite caution and granting of a grace period, Lessor is entitled to
     exchange the corresponding locks at Lessee's expense and to have new keys
     and code cards made.  On return of the Leased Property, Lessor shall
     prepare a detailed protocol of the condition of the Leased Property.
     Lessee shall assist personally in drawing up this protocol or shall be
     represented by a person authorized in writing.

4.   If the works on the Leased Property to be effected by Lessee are not
     completed on termination of Lease, the rent plus incidental expenses shall
     be paid until the end of the month of completion of such works.  Any
     additional claims on the part of Lessor remain unaffected.

5.   In the case of Lessee's premature moving, Lessor is entitled to have other
     repairs and structural alterations done in the Leased Property without
     giving rise to additional claims for crediting rent or suchlike on the part
     of Lessee.


                                      SECTION 18

                                   SALE OF PROPERTY

1.   Lessor reserves the right to sell the Property.  In this case, it shall
     induce the buyer to succeed to Lessor's rights and obligations under this
     Lease on the day of taking over the Property.  Subject to this and by
     signing this Lease, Lessee waives its rights according to Section 571,
     sub-paragraph (2) German Civil Code BGB (Liability of Lessor who sells the
     Leased Property with respect to further performance of Lease by the buyer).

2.   In the case of the Property being sold, Lessor is entitled to ask from
     Lessee a declaration of completeness, enclosing documentation of Lease.
     Lessee is then bound to inform Lessor within a period of four weeks,
     whether the list submitted by Lessor is complete and correct as regards the

1.   Deleted.
<PAGE>

2.   If one or more of the provisions of this contract are or become 
     inoperative for any reason whatsoever, the validity of the Lease shall 
     remain unaffected. In such a case, the parties shall agree on an 
     operative provision, which is as close as possible to the economic 
     purpose of the inoperative provision.

3.   No verbal collateral agreements have been entered into. Any 
     modifications or amendments to this Lease and all other declarations of 
     intention made to the other contracting party must be made in writing in 
     order to be valid. The mandatory written form applies, in particular, to 
     agreements entered into by the parties with regard to the completion of 
     the interior of the Leased Property.

4.   The contracting parties undertake to perform any actions and to 
     make any declarations, which are necessary for complying with the 
     statutory request for the written form, mandatory in particular for the 
     signing of additional, amending and supplementary contracts, and until 
     then not to terminate the Lease prematurely invoking failure to comply 
     with the mandatory written form.


                                   SECTION 20

                            SUPPLEMENTARY AGREEMENTS


Supplementing the above terms of contract, the following is agreed additionally:

1.   Lessor reserves the right to include the parking lots of the 
     Property into an parking lot management system. In such a case, only a 
     locally not determined parking space can be provided. As a compensation, 
     the rent for the parking spaces concerned shall be considerably reduced. 
     By signing this contract, Lessee declares its general consent to such a 
     modification of contract and its willingness to enter into corresponding 
     agreements with Lessor at the appropriate time.

2.   The security for rent to be provided by Lessee according to Section 
     6, sub-paragraph 3 is provided by bank guaranty.

3.   Lessor grants Lessee a contribution to construction costs required 
     in respect of alteration/completion of the leased area of up to DM
     300,000.00 against presentation of proof and invoicing.
