VDC Communications, Inc. and Subsidiaries
Notes to consolidated financial statements

1.       General

These  consolidated  financial  statements  for the three and nine month periods
ended March 31, 2000 and 1999 and the related footnote information are unaudited
and have been  prepared  on a basis  substantially  consistent  with the audited
consolidated   financial   statements  of  VDC  Communications,   Inc.  and  its
subsidiaries (collectively, "VDC" or the "Company") as of and for the year ended
June 30, 1999 included in the Company's Annual Report on Form 10-K as filed with
the Securities and Exchange  Commission (the "Annual  Report").  These financial
statements should be read in conjunction with the audited  financial  statements
and the related notes to consolidated  financial statements of the Company as of
and for the year  ended June 30,  1999  included  in the  Annual  Report and the
unaudited  quarterly  consolidated  financial  statements  and related  notes to
unaudited  consolidated  financial statements of the Company for the three month
periods ended September 30, 1999 and December 31, 1999 included in the Company's
Form 10-Q for the quarters then ended as filed with the  Securities and Exchange
Commission.   In  the  opinion  of  management,   the   accompanying   unaudited
consolidated financial statements contain all adjustments  (consisting of normal
recurring  adjustments) which management  considers  necessary to present fairly
the  consolidated  financial  position  of the  Company at March 31,  2000,  the
results of its  operations  for the three and nine month periods ended March 31,
2000 and 1999 and its cash flows for the  nine-months  ended  March 31, 2000 and
1999. The results of operations for the three and nine month periods ended March
31,  2000 may not be  indicative  of the  results  expected  for any  succeeding
quarter or for the entire year ending June 30, 2000.

The preparation of financial  statements in conformity  with generally  accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts  reported in the financial  statements.  Actual results could
differ from those estimates.

Certain  prior-year  amounts have been reclassified to conform to the year ended
June 30, 2000 financial statement presentation.

Cost of services includes  depreciation  attributable to operating  equipment of
$201,807 and  $705,164  during the three and  nine-months  ended March 31, 2000,
respectively.  Selling, general and administrative expenses include depreciation
of $22,691 and $66,478 and bad debt expense of $(11,023) and $243,479 during the
three and  nine-months  ended  March 31,  2000,  respectively.  Cost of services
includes  depreciation  attributable  to  operating  equipment  of $200,390  and
$287,626  during the three and nine-months  ended March 31, 1999,  respectively.
Selling,   general  and   administrative   expenses  include   depreciation  and
amortization  of $160,063 and $416,540  during the three and  nine-months  ended
March 31, 1999, respectively.

Loss per common share is calculated by dividing the loss  attributable to common
shares by the weighted average number of shares outstanding.  Outstanding common
stock options and warrants are not included in the loss per share calculation as
their effect is anti-dilutive.

2.       Capital Transactions

In October  1999,  the Company sold 666,667  shares of common stock to unrelated
investors and 666,667  shares to an adult son of the Company's  Chief  Executive
Officer at $0.75 per share, the public market price at that time.

In October 1999, a condition for the release from escrow of 2 million  shares of
the Company's  common stock to the seller of the investment in Metromedia  China
Corporation ("MCC"),  which consists of 2 million shares of MCC common stock and
warrants to purchase 4 million  shares of MCC common stock at $4 per share,  was
satisfied.  The condition provided for the release of the escrowed shares in the
event that the  Company's  stock price  closed  below $5.00 for 40 trading  days
during the 120  consecutive  trading days  subsequent  to August 31,  1999.  For
financial  statement  purposes,  the shares  became  issued and  outstanding  in
October  1999.  Since the Company  had  previously  determined  the value of its
investment  in MCC to be $2.4 million  under FASB No. 121, the issuance of the 2
million Company shares was charged to operations for the par value of the shares
(i.e. $200).

In March 2000,  the Company  issued  75,000  shares of Company  common  stock to
investment  bankers  for  services  arising  out  of  the  merger  of  Sky  King
Communications,   Inc.,   a   Connecticut   corporation   with   and   into  VDC
Communications,  Inc. (then a wholly-owned subsidiary of VDC Corporation Ltd., a
Bermuda  company)  on March 6, 1998 (the "Sky King  Merger").  The  shares  were
issued at the fair market  value as of the date of the merger  ($2.50 per share)
and a corresponding  charge to accumulated  deficit.  In April 2000, the Company
satisfied the investment  banking fees by issuing an additional 52,500 shares of
Company common stock to investment  bankers for services  arising out of the Sky
King Merger.

In April 2000,  the Company sold 540,000  shares of Company  common stock to the
Chairman and C.E.O. at $2 per share, the public market price at that time.

3.       Option Repricing

In light of the  decline in market  price of the  Company's  common  stock as of
October 1999, the Board of Directors believed that the outstanding stock options
with an exercise  price in excess of the actual  market  price were no longer an
effective  tool to encourage  employee  retention or to motivate  high levels of
performance.  As a result,  in October 1999, the Board of Directors  approved an
option  repricing  program under which options to acquire shares of common stock
that were  originally  issued with  exercise  prices  above $1.25 per share were
reissued with an exercise price of $1.25 per share, the fair market value of the
common stock at the  repricing  date.  These options will continue to vest under
the original  terms of the option grant.  Options to purchase  757,500 shares of
Company common stock were affected by the repricing program including options to
purchase  567,500  shares of common stock issued under the Company's  1998 Stock
Incentive  Plan, as amended (the "Plan") and options to purchase  190,000 shares
of common stock issued outside of the Plan.

In March 2000, the Financial  Accounting  Standards  Board ("FASB")  issued FASB
Interpretation  No. 44  "Accounting  for Certain  Transactions  involving  Stock
Compensation  an  interpretation  of APB  No.  25".  Among  other  issues,  this
Interpretation  clarifies the accounting consequence of various modifications to
the terms of a previously  fixed stock option or award. The  pronouncement  will
require a charge to  operations  for the  difference  between the quoted  market

                                       7
<PAGE>

value of the Company's  common stock at the end of each reporting period and the
option price of unexercised,  outstanding  stock options.  The  pronouncement is
effective July 1, 2000 but covers events that occur after December 15, 1998.

4.       Investment in MCC

The Company is a passive minority  shareholder of Metromedia  China  Corporation
("MCC"). As such, the Company makes no representations regarding the accuracy of
the  information   publicly   provided  by  MCC's  majority  owner,   Metromedia
International Group ("MMG"), from which the following summary is derived:

         MCC's  telephony  joint  ventures were  terminated in late 1999 and MMG
         reached  agreement  with  China  Unicom,  its  Chinese  partner  in the
         ventures for the distribution of approximately  $90.1 million (based on
         the December 31, 1999 exchange  rate) in settlement of all claims under
         the joint  ventures,  of which $29.3  million has been  received.  Over
         time, MMG anticipates that it will fully recover its investments in and
         advances to the four affected joint ventures,  but no assurances can be
         made  as to the  exact  timing  or  amount  of such  repayments.  As of
         December  31,  1999,  investment  in and  advances  to these four joint
         ventures, exclusive of goodwill, were approximately $40.0 million.

         Full  distribution  of  all  expected  funds  must  await  the  Chinese
         government's  recognition  and  approval  of the  completion  of formal
         dissolution  proceedings for the four joint ventures.  This is expected
         by mid-2000 and MMG  anticipates  no problems in ultimately  dissolving
         the joint ventures.

         MCC has recently  developed  interests in an Internet  joint venture in
         China, Huaxia Metromedia  Information  Technology Co., Ltd. ("Huaxia").
         Huaxia is not engaged in any  cooperation  with China Unicom and is not
         affected by the China Unicom project termination agreements. Huaxia was
         established  as a sino-foreign  equity joint venture  between MCC and a
         Chinese trading  company.  The joint venture  develops and operates the
         Internet-based information systems that the Chinese partner uses in its
         electronic trading activities.  This form of outsourcing arrangement is
         allowed  under  current   Chinese   regulation.   MCC  is  actively  in
         negotiation for the formation of several similar ventures  operating in
         other regions and commercial sectors of China.

During the year ended June 30, 1999, VDC recorded a $21,328,641 writedown of the
investment in MCC in accordance  with FASB No. 121. At that time, the write-down
adjusted the carrying  value of the  investment in MCC to an amount  relative to
MMG's carrying amount,  excluding MMG's goodwill  attributable to the investment
in MCC. As such,  VDC adjusted the carrying  value of its  investment  in MCC to
$2.4 million at June 30, 1999.

5.       Note Payable-Officer

In September  1999,  the Chairman and CEO loaned the Company  $80,000.  The note
bears interest at 8% per annum and is due in September  2000. In April 2000, the
Company repaid the note and accrued interest in full.

6.       Commitments and Contingencies

Disputed Claims

The Company has accrued $1.1 million in current  liabilities for disputed claims
including liabilities  attributable to a wholly-owned  subsidiary of the Company
(the "Subsidiary"). The Company has decided to reflect the potential liabilities
of the Subsidiary  within its financial  statements  despite the fact management
has  reason to  believe  that the  Subsidiary  may not be  responsible  for such
potential  liabilities  and  despite  the fact that the  subsidiary  has limited
assets and would be unable to pay this  liability,  if it were, in fact,  liable
for it.  Moreover,  due to the fact  that  the  potential  liability  would be a
liability  of  the  Subsidiary,   a  separate  legal  entity,  and  not  of  VDC
Communications, Inc., the parent company, management believes that the potential
liability  will not impact the assets of the parent or its  subsidiaries,  other
than the Subsidiary.

Litigation

In July 1999, a former  customer  filed suit against the Company  asserting that
the Company  induced it to enter into an  agreement  through  various  purported
misrepresentations.   The   suit   alleges   that,   due  to   these   purported
misrepresentations  and purported breaches of contract,  the former customer has
been unable to provide  services to its  customers.  The relief sought  includes
monetary  damages  resulting  from the  purported  breach  of  contract  and the
purported  misrepresentations  and the recovery of attorneys' fees. In the event
that the former  customer  prevails,  the Company  could be liable for  monetary
damages in an amount that would have a material  adverse effect on the Company's
assets and operations.

The Company  believes that the claims asserted are without merit and the Company
will, if it is served with process,  vigorously  defend itself  against them. In
the opinion of management, based on the information that it presently possesses,
the claims will not have a material adverse effect on the Company's consolidated
financial position, results of operations or liquidity.

7.       Subsequent Events

In April 2000,  the Company  reached an agreement  to acquire a privately  owned
U.S. retail long distance  carrier  ("Telephony  Carrier") for 1,632,653  common
shares and the assumption of approximately $300,000 of debt (the "Transaction").
In April  and May of 2000,  the  Company  loaned  Telephony  Carrier  a total of
$300,000 at 0% interest. The loans are due on October 20, 2000. In consideration
for the Company  agreeing to make the loans and  agreeing to forego  interest on
the principal  amount of the loans,  Telephony  Carrier shall pay the Company $2
million if Telephony  Carrier does not  consummate  the  Transaction  on certain
terms.

8.       Supplemental Disclosure of Cash Flow Information

For purposes of the  statement of cash flows,  the Company  considers all highly
liquid  investments with an original maturity of three months or less to be cash
equivalents.

In  December  1999,  the  Company  sold a fixed  asset with a carrying  value of
approximately  $383,000.  The  consideration  received was the assumption by the
buyer of the related capital lease  obligation of  approximately  $438,000.  The
difference has been recorded as a gain on the disposal of fixed assets.

General

VDC  Communications,  Inc.  (referred to herein as the "Company,"  "we" or "us")
owns    telecommunications    switching   and   ancillary   equipment,    leases
telecommunications  lines and  interconnects  a global  network of carriers  and
customers providing domestic and international long distance  telecommunications
services.  Our customers are other long distance telephone companies that resell
our services to their retail customers or other telecommunications companies. In
the future, we anticipate  offering our services directly to retail customers in
addition  to our  current  wholesale  customers.  We  currently  employ  digital
switching and transmission technology,  and expect to deploy Internet Telephony,
or Voice over Internet  Protocol  ("VoIP") gateway  technology in the near term.
Our circuit switched telecommunications  equipment,  located in New York and Los
Angeles comprises our operating  facilities.  We expect to add VoIP equipment to
one or both of these locations in the future.

We believe the telecommunications  industry is attractive given its current size
and future  growth  potential.  We are  currently a domestic  and  international
telecommunications  company providing wholesale carrier services.  Our objective
is to provide these  services to both retail and wholesale  customers  utilizing
VoIP and circuit switched technologies in the short term; and, migrating towards
a pure VoIP  network  in the long term.  We have  already  begun the  process of
transforming our network with next generation technology.

During the quarter  ended March 31, 2000, we initiated  the  development  of the
Company's   VoIP   network   through   its    wholly-owned    subsidiary,    VDC
Telecommunications,  Inc. ("VDC Telecom"). We expect that utilizing new Internet
technologies to provide voice and facsimile, and possibly additional value added
services in the future,  will provide us: (i) increased cost efficiencies;  (ii)
greater network  flexibility;  and, (iii) an increased  network scope. We expect
that this can be achieved with a relatively  minimal capital outlay.  During the
quarter,  we began the  development  of this  network  through  VDC  Telecom by:
ordering IP, or Internet Protocol, gateway equipment; provisioning to connect to
the Internet;  and,  agreeing to the trial of a  clearinghouse  capability.  Our
clearinghouse is expected to provide for wholesale  customers to connect and use
our network via the public  Internet.  We expect that we may use our  developing
Internet  network for  dedicated,  or private  network,  connections  to certain
customers as well. We expect to begin the clearinghouse trial during the quarter
ending  June 30,  2000.  Our  ability to begin this  trial is  dependent  on the
delivery of the necessary  equipment and  connectivity  to the public  Internet,

                                       11
<PAGE>

among  other  things.  After  the  network  is  operational  and if the trial is
successful, we expect to begin delivering traffic via this mechanism.

We expect that the introduction of a VoIP network alongside our existing network
will benefit the Company and its customers.  However,  there are increased risks
to the Company as a result of this development. These risks include, but are not
limited to: the quality of call completion over the Internet;  network  capacity
constraints;  our ability to fund and  develop  this new  business;  the intense
level of competition in this industry subsection; risks associated with starting
a new business;  risks involved in utilizing a new  technology;  risk of network
complication and/or failure;  domestic and international  government  regulation
and legal uncertainties;  increased volatility in our stock; and, numerous other
risks, some of which we may not be fully aware of currently.  If any one or more
of these risks factors proves significantly different than our expectations,  it
could have a material adverse effect on us. Furthermore, it is possible that the
cost to  develop  and  operate  this  network  may be greater  than our  current
expectation. This would have a material adverse effect on us.

In February  2000, we began to carry  telecommunications  traffic for one of the
largest U.S.  long distance  carriers.  In April 2000,  that customer  initiated
sending traffic through us to a second destination  country.  In addition,  that
customer has  indicated  to us that it expects to send traffic  through us to as
many as five  destination  countries in the short term.  While this  customer is
currently our third  largest,  we expect it could become our largest  during the
remainder of calendar 2000.

In a prior filing,  we stated that we were  exploring the  development of retail
long distance through VDC Telecoms' subsidiary, WorldConnectTelecom.com, Inc. We
have  determined  that we will not develop our retail long  distance  capability
through this subsidiary at this time.  However, we are currently exploring other
ways to develop this  business,  which we expect would  complement our wholesale
operations.

Subsequent  to March 31, 2000, we came to an agreement to acquire 100% of a U.S.
based  telecommunications  company ("Telephony Carrier") providing long distance
services  to U.S.  retail  customers.  Upon  completion  of VDC's due  diligence
investigation,  its Board of Director's approval of the transaction,  regulatory
approval if required, and the execution of proper closing documents, among other
things, the consideration  given will consist of 1,632,653 Company common shares
and the assumption of approximately $300,000 of debt.

Telephony  Carrier has been offering  retail long distance  services to domestic
customers only since December,  1999. As of April 30, 2000, it had approximately
3,500 customers.  Through its subsidiaries,  it currently employs  approximately
190  salespeople.  Telephony  Carrier's  April 2000 annualized run rate revenues
were approximately $3.9 million.  Telephony Carrier has two retail long distance
marketing  concepts.  The first concept entices prepaid  telemarketed  customers
with monthly rebates and various other incentives.  The other concept,  which is
not yet operational,  will utilize Telephony  Carrier's exclusive right to use a
patent-pending  Internet driven customer  acquisition process that the Telephony
Carrier plans to employ to market its telephony  services over the Internet.  It
is  anticipated  that this right to use will be granted upon  completion  of the
acquisition.

The acquisition of Telephony Carrier is expected to both  substantially  broaden
our telephony  customer  base, as well as strengthen  our ability to utilize the
Internet, both: (i) to deliver telecommunications services; and, (ii) to procure

                                       12
<PAGE>

telephony  customers.  This  development  of a retail long distance  business is
expected to result in increased:  funding needs;  regulatory  compliance  costs;
customer  service  needs;  potential  for employee  issues;  exposure to pricing
pressure in the domestic long distance  market;  potential for fraud;  potential
for harm due to network  failure;  potential  for  increased  volatility  in our
stock; and numerous additional risks, which may not be known to us at this time.
If any one or more of  these  risks  proves  significantly  different  than  our
expectations, it could have a material adverse effect on us.

We earn  revenue  from  three  sources.  The first  source is our  domestic  and
international telecommunications long distance services which is earned based on
the number of  minutes  billable  to our  customers,  which are other  telephone
companies.  These minutes are  generally  billed on a monthly  basis.  Bills are
generally  due within  zero to thirty  days.  Our second  source of  revenues is
derived from the rental of space and  telecommunications  equipment and circuits
at our telecommunications facilities ("Partition") to other telephone companies.
This  revenue is  generated  and  billed on a  month-to-month  basis.  We expect
Partition  revenue to decrease  significantly  during the  remainder of calendar
2000. Our third source of revenue is from the management of domestic tower sites
that provide  transmission  and receiver  locations for wireless  communications
companies. This revenue is also generated and billed on a month-to-month basis.

Revenue  derived  through the  per-minute  transmission  of voice and  facsimile
telecommunications  traffic is normally in accordance  with contracts with other
telecommunications  companies. These contracts are often for a year or more, but
can  generally  be amended  with a few days  notice.  Further,  these  contracts
generally do not provide for a fixed volume of telecommunications  traffic to be
sent to us and, as such, the telecommunications traffic that a customer sends to
us during any given month can vary considerably.  Occasionally,  however,  these
contracts  require  payments to us if a customer  does not send a fixed  minimum
amount of telecommunications traffic to us.

Costs of services is primarily  comprised of costs  incurred from other domestic
and foreign  telecommunications  carriers to originate,  transport and terminate
calls that we send to them.  The  majority  of our cost of service is  variable,
based on the number of minutes of use, with  transmission and termination  costs
being our most significant  expense. In addition,  our costs of services include
circuit  expenses,   the  allocable   personnel  and  overhead  associated  with
operations, and depreciation of telecommunications equipment. We depreciate long
distance telecommunications equipment over a period of five years.

Our costs also include selling,  general, and administrative  expenses ("SG&A").
SG&A consists primarily of personnel costs,  professional  fees, travel,  office
rental and business  development  related costs. We incur costs  associated with
international and VoIP market research, the development of the VoIP strategy and
deployment, and due diligence regarding potential projects inside and outside of
the U.S.

Results of Operations

For  the  Three  Months Ended  March 31, 2000 Compared to the Three Months Ended
March 31, 1999

                                       13
<PAGE>

Revenues:  Total  revenues in the three  months  ended March 31, 2000  ("Current
Quarter")  increased to approximately $2.1 million from  approximately  $697,000
for the three months ended March 31, 1999 ("Prior Period  Quarter").  Revenue of
approximately  $1.7  million was  generated  during the  Current  Quarter by the
transmission of approximately 5.8 million minutes of telecommunications  traffic
domestically and internationally  ("Long Distance  Revenue").  We also generated
revenue of  approximately  $343,000 from Partition,  approximately  $12,000 from
contractually  required payments from a customer due to its failure to provide a
certain minimum level of  telecommunications  traffic and approximately  $30,000
from site tower  management.  Revenue of  approximately  $537,000 was  generated
during the Prior Period Quarter by the transmission of approximately 2.3 million
minutes of telecommunications traffic internationally. We also generated revenue
of  approximately  $129,000 from Partition and  approximately  $30,000 from site
tower management during the Prior Period Quarter.

Costs of  Services:  Costs of  services  in the  Current  Quarter  increased  to
approximately  $2 million  from  approximately  $1.2 million in the Prior Period
Quarter. The increase is due to increased domestic and international  minutes of
telecommunications  traffic which we purchased from other long distance carriers
and increased operational expenses including salaries, depreciation, and circuit
costs.  Costs of services as a percentage of revenues decreased from 167% in the
Prior  Period  Quarter to 95% in the Current  Quarter.  The  decrease was mostly
attributable to improved rates, increased traffic volume and lower fixed monthly
circuit costs.

Selling,  general & administrative expenses ("SG&A"): SG&A expenses decreased to
approximately $467,000 in the Current Quarter from approximately $2.2 million in
the Prior Period  Quarter.  This decrease was primarily the result of reductions
in personnel costs and  professional  fees as a result of cost cutting  measures
implemented  to increase  overall  efficiencies.  The Prior Period  Quarter also
included  one-time  write-offs  and  severance  expenses of  approximately  $1.0
million.

Other income (expense): Other income (expense) was approximately $59,000 for the
three months ended March 31, 2000 compared with  approximately  $(19.4)  million
for the Prior Period Quarter.  Other income (expense) in the current quarter was
due to interest expense incurred on capital lease obligations offset by interest
income and the gain on a sale of telecommunications  equipment.  Other (expense)
in the Prior  Period  Quarter  was mostly due to an  approximate  $19.4  million
writedown of the investment in MCC.

For the Nine-months Ended March 31, 2000 Compared to the Nine-months Ended March
31, 1999

Revenues:  Total  revenues in the  nine-months  ended  March 31, 2000  ("Current
Period") increased to approximately $6.6 million from approximately $1.4 million
for the nine-months ended March 31, 1999 ("Prior Period"). Long Distance Revenue
of  approximately  $5.4 million was generated  during the Current  Period by the
transmission of approximately 24.2 million minutes of telecommunications traffic
domestically  and  internationally.  We also generated  revenue of approximately
$819,000  from   Partition,   approximately   $253,000  from  the  shortfall  of
contractual traffic termination requirements and approximately $92,000 from site
tower  management.  Long  Distance  Revenue of  approximately  $1.2  million was
generated during the Prior Period by the transmission of approximately 4 million
minutes of telecommunications  traffic internationally.  In the Prior Period, we
also generated revenue of approximately  $172,000 from Partition,  approximately

                                       14
<PAGE>

$75,000 from site tower  management and  approximately  $48,000 of non-recurring
revenue.

Costs  of  Services:  Costs of  services  in the  Current  Period  increased  to
approximately  $6.8 million from approximately $2.4 million in the Prior Period.
This  increase  reflects  increased   domestic  and  international   minutes  of
telecommunications  traffic which we purchased from other carriers and increased
operational expenses including salaries,  depreciation, and circuit costs. Costs
of services as a percentage of revenues  decreased from 172% in the Prior Period
to 104% in the Current Period. The decrease was mostly  attributable to improved
rates and increased traffic volume.

Selling,  general & administrative expenses ("SG&A"): SG&A expenses decreased to
approximately $1.8 million in the Current Period from approximately $4.2 million
in the Prior  Period.  This  decrease was  primarily the result of reductions in
personnel  costs  and  professional  fees  as a part of  cost  cutting  measures
implemented to increase overall efficiencies.

Other income (expense):  Other income (expense) was approximately $36,000 in the
current period compared with approximately  $(21.1) million in the Prior Period.
Other income  (expense) in the Current Period was mostly due to interest expense
incurred on capital lease obligations  offset by interest income and a gain on a
sale of  telecommunications  equipment.  Other (expense) in the Prior Period was
due to a writedown of the investment in MCC and a loss on note restructuring.

Liquidity and Capital Resources

Our  liquidity   requirements  arise  primarily  from  cash  used  in  operating
activities,  capital expenditures and payments of capital lease obligations.  To
date, we have financed ourselves mostly through equity financing.  We anticipate
our near term liquidity  requirements to be approximately $1.2 million, to fund:
(i) Telephony  Carrier  during its ramp up phase;  (ii) ongoing  operating  cash
deficits, if any; and (iii) certain cash outlays for the development of our VoIP
network.  The $1.2 million  does not include a $300,000  bridge  financing  loan
already made to Telephony  Carrier.  As of April 28, 2000, we had  approximately
$1.9 million in cash to meet these anticipated expenditures.

We  implemented  cost-cutting  measures  during the  current  fiscal  year which
included the following:

         1.   Reduced  circuit costs by over 50% by eliminating  unused capacity
              and more fully utilizing remaining capacity.
         2.   Obtained a release  from the vendor on an  equipment  lease for an
              asset that was not a  strategic  fit for our  current  network and
              would have cost approximately  $16,800 per month beginning January
              2000.
         3.   Reduced our employees from 29 at September 14, 1999 to 18 at March
              31, 2000.
         4.   Amended  our lease  space in our  Colorado  office  which  reduced
              Colorado office rent by approximately 40 percent. In addition,  as
              of May 2000, rent was further reduced by approximately 20%.

We  experienced  our strongest  results to date during the months ended March 31
and April 30, 2000.  Our  earnings  before  interest,  taxes,  depreciation  and
amortization  ("EBITDA") were approximately  $(1,000) and $15,000 for the months

                                       15
<PAGE>

ending  March 31 and April  30,  2000,  respectively.  We  expect  our  existing
operations (i.e., operations excluding Telephony Carrier) to continue to operate
at or near  breakeven  EBITDA in the short term.  EBITDA is a financial  measure
commonly used in the telecommunications  industry.  Still, EBITDA is not derived
from generally accepted  accounting  principles ("GAAP") and therefore investors
should not  consider it as  indicative  of  operating  income or cash flows from
operating activities,  as determined in accordance with GAAP, or as a measure of
liquidity.  Also,  our  calculation  of EBITDA  does not take into  account  our
existing  commitments  for  capital  expenditures  and  should  not be  seen  as
representative of the amount of funds generally available to us.

Although our cash and operating results have improved  significantly  during the
past nine months,  the American Stock Exchange  ("AMEX") has notified us that we
fall below certain of AMEX's continued  listing  qualifications.  As such, there
can be no  assurances  of continued  listing.  Nevertheless,  we believe  AMEX's
notification  results mainly from the going concern issue raised by our auditors
at June 30,  1999 year end. We have taken  numerous  steps since then to address
this  issue,  including:  (i) raising  $2.0  million  through a private  sale of
equity; and (ii) substantially  reduced overhead costs and operational expenses.
As a result  of  these  actions,  we have  reduced  our  negative  EBITDA,  from
approximately  ($1.4)  million  during the June 1999  quarter  to  approximately
$(150,000)  during the quarter ended March 31, 2000; and, our available cash has
increased from $318,000 at June 30, 1999 to approximately  $1.9 million at April
28, 2000. We believe our auditors issued a going concern opinion based primarily
on the fact that our cash  position at June 30, 1999 was not  sufficient to fund
twelve months of losses at the then current  rate. By way of contrast,  at March
31, 2000, we had  sufficient  cash to fund the current rate of operating  losses
for the next twelve months.

Furthermore,  additional  funds may come available to us, including the expected
sale of our Colorado based switch.  We expect that any success in monetizing the
switch and/or other non-strategic assets would further improve liquidity.

As previously discussed, on April 24, 2000, we announced an agreement to acquire
Telephony  Carrier.  Telephony  Carrier only recently  began  operations  and is
currently  experiencing  negative EBITDA,  which should continue to occur for at
least the next several months. Based upon our current understanding,  we believe
that Telephony  Carrier's cash needs during the expected ramp up of its business
are manageable. In connection with the acquisition,  we are providing short-term
financing to cover Telephony  Carrier's  current  negative cash flow.  While our
negative EBITDA declined significantly  during the quarter ended March 31, 2000,
the acquisition of Telephony  Carrier is expected to significantly  increase our
propensity  to  experience  negative  cash flow in the near term.  We  currently
expect that the completion of this  acquisition,  while depletive of cash in the
near term, will provide significant returns in the future.

In the expected  event that the  acquisition  of Telephony  Carrier  closes,  we
consider it less likely we will pursue other  acquisition  opportunities  in the
short term. Although we would likely use our common stock for acquisitions, such
acquisitions may have a significant impact on our need for capital. In the event
of a need for capital in  connection  with an  acquisition,  we would  explore a
range of financing  options,  which could  include  public or private  debt,  or
equity  financing.  There  can be no  assurances  that  such  financing  will be
available, or if available,  will be available on favorable terms.  Furthermore,
any acquisition may increase our cash losses from  operations,  thereby reducing
our liquidity.

                                       16

We are projecting  capital  expenditures of  approximately  $300,000 to $400,000
during the  remainder  of calendar  2000.  The capital  expenditures  are mainly
associated with our VoIP strategy and represent telecommunications equipment. We
expect to fund these purchases through vendor debt financing or equity financing
and cash flow from  operations,  if any.  Although  we do not  expect  Telephony
Carrier's capital  expenditures to be material,  we expect to revise our capital
expenditure projections if the Telephony Carrier acquisition is consummated.

We expect our existing  operations to continue to operate at or near  breakeven,
on an EBITDA  basis,  in the short term. We expect to close the  acquisition  of
Telephony  Carrier  prior  to  fiscal  year end June 30,  2000.  We  expect  the
acquisition  to result in increased  earnings per share and EBITDA losses in the
short term.  However,  we believe our current  cash  position,  including  funds
raised in April 2000,  should prove  sufficient  to meet the expected  liquidity
requirements of the Company and Telephony Carrier in the short term.

To meet  liquidity  requirements  in the  long  term,  we need to  increase  our
revenues  and  gross  profit,  which  will most  likely  occur as a result of an
increase in minutes passed by new or existing  customers,  and/or as a result of
the ramp-up of Telephony Carrier.  There are no assurances,  however, that these
long term objectives will transpire.

In order to meet these long term  objectives,  we  believe we have  developed  a
network that  provides  competitive  telecommunications  services and  Telephony
Carrier has developed a marketing  capability  that is  competitive  in customer
acquisition.  We expect that we will  continue to operate and market the network
to build our customer base and that  Telephony  Carrier will continue to acquire
customers.

Net cash provided by operating activities was approximately  $36,000 in the nine
months ended March 31, 2000, or Current Period. We collected  approximately $7.0
million  from  customers  while paying  approximately  $6.9 million to carriers,
other  vendors  and  employees.  Net  cash  used  by  operating  activities  was
approximately  $2.6 million in the nine months  ended March 31,  1999,  or Prior
Period. In that period, we collected  approximately  $1.0 million from customers
while paying approximately $3.6 million to vendors and employees.

Net cash  provided by investing  activities  was  approximately  $336,000 in the
Current  Period.  Cash flows  provided  by  investing  activities  included  the
collection of notes  receivable  and a sales tax refund on  previously  acquired
switching equipment.  Cash was used for fixed asset acquisitions.  Net cash used
by investing activities was approximately $1.5 million in the Prior Period. This
was the result of capital  expenditures,  the acquisition of a subsidiary and an
investment in an affiliate,  net of collections on notes receivable and proceeds
from the return of escrow in connection with the Company's investment in MCC.

Cash provided by financing activities was approximately  $709,000 in the Current
Period.  This reflects proceeds from the issuance of common stock and short-term
debt  less  repayments  on  capital  lease  obligations.  Proceeds  provided  by
financing  activities of approximately $2.1 million during the Prior Period were
from  collections  on stock  subscriptions  receivable,  the  issuance of common
stock, proceeds from short term debt less the repayment of a note.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

The Company is currently  not exposed to material  future  earnings or cash flow
exposures from changes in interest rates on long-term debt obligations since our
long-term debt obligations are at fixed rates.

The Company's carrying value of cash and cash equivalents,  accounts receivable,
accounts payable,  marketable  securities-available  for sale, and notes payable
are a reasonable approximation of their fair value.

                       MASTER AGREEMENT TO LEASE EQUIPMENT


         THIS MASTER AGREEMENT TO LEASE EQUIPMENT (this  "Agreement") is entered
into as of February 22, 2000 by and between  CISCO SYSTEMS  CAPITAL  CORPORATION
("Lessor"),  having its  principal  place of business at 170 West Tasman  Drive,
Mailstop SJC2, 3rd Floor, San Jose, California 95134 and VDC TELECOMMUNICATIONS,
INC., a Delaware corporation ("Lessee"),  having its principal place of business
at 75 Holly Hill Lane, Greenwich, Connecticut 06830.



                                  1. THE LEASE
                                     ---------

         1.1    Lease of Equipment.  In accordance with the terms and conditions
of this  Agreement,  Lessor  shall lease to Lessee,  and Lessee shall lease from
Lessor,  the personal  property  described  in the lease  schedule(s)  (each,  a
"Schedule")  to be entered  into from time to time into which this  Agreement is
incorporated (each Schedule,  together with this Agreement, a "Lease"), together
with  all   substitutions,   replacements,   repairs,   parts  and  attachments,
improvements and accessions  thereto (the  "Equipment").  Capitalized  terms not
otherwise  defined  in  this  Agreement  have  the  meanings  specified  in  the
applicable  Schedule.  Each Lease shall  constitute  a separate,  distinct,  and
independent lease and contractual  obligation of Lessee. Except as expressly set
forth in any Lease, Lessor shall at all times retain the full legal title to the
Equipment,  it being  expressly  agreed by both  parties  that each  Lease is an
agreement of lease only.

         1.2    Equipment  Procurement.  Lessee  has  ordered  or  may order the
Equipment  pursuant  to  one or  more  purchase  orders  or  purchase  contracts
(together, "Purchase Order") to or with Cisco Systems, Inc., or a Cisco-approved
reseller (together,  "Vendor"), which Purchase Order shall be promptly delivered
to Lessor in the event that the parties agree to enter into a lease  transaction
with  respect  to the  Equipment  described  in such  Purchase  Order.  Lessor's
agreement  to enter  into such a lease  transaction  is  evidenced  by  Lessor's
preparation and delivery of a Schedule,  and the terms of such agreement will be
set forth in such Schedule,  provided, however, that the terms of this Agreement
are hereby incorporated into every Schedule whether or not such incorporation is
stated therein. Lessor's failure or refusal to deliver a Schedule to Lessee will
not constitute a breach of this Agreement or of any Lease. Lessee's agreement to
enter into such a lease  transaction  according  to the terms of the  previously
delivered  Schedule is  evidenced by Lessee's  execution  of the Purchase  Order
together with either notification of its decision to execute the Schedule or the
absence of any  affirmative  notification  from Lessee that it has not agreed to
execute the Schedule delivered to it (i.e. silence by Lessee up to and including
the time  that  Lessee  executes  a  Purchase  Order is  deemed  to be  Lessee's
agreement to execute the Schedule).

         If it agrees or is deemed to agree to lease from  Lessor,  then  Lessee
shall execute and return to Lessor (a) each Schedule within ten days of Lessee's
receipt of same, and (b) all related or  accompanying  Certificate of Acceptance
within ten days of receipt and  acceptance  of the  applicable  Equipment.  Upon
Lessee's  agreement  or deemed  agreement  to lease from  Lessor  (as  evidenced

<PAGE>

above),  Lessee shall be deemed to have  assigned to Lessor all Lessee's  right,
title and interest in and to the Equipment and the Purchase Order; provided that
Lessor  shall have no  obligations  under the  Purchase  Order other than as set
forth in the next  sentence.  Upon  Lessee's  execution of each Schedule and the
related  Certificate(s)  of Acceptance,  and subject to the following  sentence,
Lessor shall cause the purchaser's  obligations  with respect to that portion of
the purchase  price  contained in such  Purchase  Orders which is subject to the
Lease (as set forth in the Schedule) to be discharged.  Notwithstanding anything
to the contrary  contained herein, if for whatever reason a lease transaction in
respect  of the  Equipment  or a  Purchase  Order  is not  consummated,  then no
assignment of the Purchase  Order shall have  occurred,  and Lessee shall remain
solely liable to pay Vendor in accordance  with the Purchase Order. In the event
that  Lessee  does not  execute  the  Schedule  and  related  Certificate(s)  of
Acceptance  or  that  Lessor  determines  that no  lease  transaction  has  been
consummated  for any other  reason but that Vendor may seek  payment from Lessor
anyway,  then the Purchase Order will not be returned to Lessee, and Lessee will
have no rights  thereunder  until Lessee has fully paid the  Purchase  Order and
provided Lessor with proof of such full payment.

         1.3    Term of Lease.  The Original  Term of each Lease shall begin  on
the  Commencement  Date as specified in the applicable  Schedule and, subject to
Sections 3.5 and 4.2,  shall  terminate on the date  specified in the applicable
Schedule.  If so provided in the applicable Schedule,  the Original Term for any
Lease may be succeeded by one or more  Extended  Terms.  Subject to Sections 3.5
and 4.2 and any express  provisions of the Schedule,  no Lease may be terminated
by Lessor or Lessee, for any reason whatsoever, prior to the end of the Original
Term or any pending Extended Term.

         1.4    Rental Payments.  Lessee shall pay Lessor Rent for the Equipment
in the amounts and at the times specified in the applicable  Schedule.  All Rent
and other amounts payable by Lessee to Lessor  hereunder shall be paid to Lessor
at the address  specified  above, or at such other place as Lessor may designate
in writing to Lessee from time to time.

         1.5    Return of Equipment.  If Lessee  has not  exercised  a  purchase
option,  if any, with respect to the  Equipment,  then,  upon  expiration of the
Lease Term,  Lessee  shall  immediately  return the  Equipment  to Lessor in the
condition and at the place provided in Section 3.3.

              2. DISCLAIMERS AND WARRANTIES; INTELLECTUAL PROPERTY
                 -------------------------------------------------

         2.1    Disclaimers;  Warranties.  Lessee  represents  and  acknowledges
that the Equipment is of a size,  design,  capacity and manufacture  selected by
it,  and that it  expects  that  the  Equipment  is  suitable  for its  purposes
(provided,  that upon executing a Certificate of Acceptance,  Lessee  represents
that the Equipment is suitable for its purposes). LESSEE LEASES THE EQUIPMENT AS
IS, AND, NOT BEING THE MANUFACTURER OF THE EQUIPMENT,  THE MANUFACTURER'S  AGENT
OR THE SELLER'S AGENT,  LESSOR MAKES NO WARRANTY OR  REPRESENTATION,  EXPRESS OR
IMPLIED, AS TO THE MERCHANTABILITY,  FITNESS FOR ANY PARTICULAR PURPOSE,  DESIGN
OR CONDITION OF THE EQUIPMENT.  LESSOR SHALL NOT BE RESPONSIBLE  FOR ANY LOSS OR
DAMAGE   RESULTING   FROM  THE   INSTALLATION,   OPERATION   OR  OTHER  USE,  OR
DEINSTALLATION OF THE EQUIPMENT,  INCLUDING ANY DIRECT, INDIRECT,  INCIDENTAL OR

                                       2
<PAGE>

CONSEQUENTIAL  DAMAGES OR LOSS.  Lessee shall look solely to the manufacturer or
the supplier of the Equipment for correction of any problems that may arise with
respect thereto, and all transferable  manufacturer and supplier warranty rights
are, to the extent such rights have been transferred to Lessor,  hereby assigned
without representation or warranty by Lessor to Lessee for the Lease Term, which
warranties Lessee is authorized to enforce (except that Lessee is not authorized
to  enforce  such  rights if and when there  exists an Event of Default  and the
enforcement of such rights would materially hamper,  delay or prejudice Lessor's
enforcement  rights and remedies  hereunder).  Any such enforcement  shall be at
Lessee's sole cost and expense.

         2.2    Intellectual Property.  Lessee acknowledges  that  neither  this
Agreement nor any Lease conveys any explicit or implicit  license for the use of
software or other intellectual property of Cisco Systems, Inc. or its affiliates
relating  to the  Equipment  and that such  license  rights,  to the extent they
exist, are contained in separate  documentation  entered into between Lessee and
Cisco  Systems,   Inc.  or  other   persons.   LESSOR  MAKES  NO  WARRANTIES  OR
REPRESENTATIONS  WHATSOEVER WITH RESPECT TO THE  INTELLECTUAL  PROPERTY  RIGHTS,
INCLUDING ANY PATENT,  COPYRIGHT AND TRADEMARK  RIGHTS,  OF ANY THIRD PARTY WITH
RESPECT TO THE EQUIPMENT,  WHETHER RELATING TO INFRINGEMENT OR OTHERWISE. Lessor
shall, when reasonably requested in writing by Lessee,  provided there exists no
Event of Default and an indemnity satisfactory to Lessor is delivered by Lessee,
and at Lessee's cost and expense, enforce rights of indemnification, if any, for
patent,  copyright or other intellectual property infringement obtained from the
manufacturer  under any  agreement  for purchase of the  Equipment.  If notified
promptly in writing of any action  brought  against Lessee based on a claim that
the Equipment infringes a United States patent,  copyright or other intellectual
property  right,  Lessor  shall  promptly  notify the  manufacturer  thereof for
purposes of exercising,  for the benefit of Lessee, Lessor's rights with respect
to such claim under any such agreement.

                              3. LESSEE OBLIGATIONS
                                 ------------------

         3.1    Net Lease; Payments  Unconditional.  EACH LEASE IS A NET  LEASE,
AND ALL COSTS, EXPENSES AND LIABILITIES RELATING TO THE EQUIPMENT,  INCLUDING IN
RESPECT OF TAXES,  INSURANCE AND  MAINTENANCE,  SHALL BE BORNE SOLELY BY LESSEE.
EXCEPT IN THE EVENT  THAT  LESSOR  OR ITS  AGENTS  REPOSSESS  THE  EQUIPMENT  IN
MATERIAL BREACH OF THE TERMS OF THIS AGREEMENT,  LESSEE'S  OBLIGATION TO PAY ALL
RENT  AND  OTHER  SUMS  THEREUNDER,  AND THE  RIGHTS  OF  LESSOR  IN AND TO SUCH
PAYMENTS,  SHALL BE ABSOLUTE AND UNCONDITIONAL,  AND SHALL NOT BE SUBJECT TO ANY
ABATEMENT, REDUCTION, SETOFF, DEFENSE, COUNTERCLAIM,  INTERRUPTION, DEFERMENT OR
RECOUPMENT, FOR ANY REASON WHATSOEVER.

         3.2    Use of Equipment.  Lessee shall use the Equipment  solely in the
conduct  of its  business,  in a  manner  and for the  use  contemplated  by the
manufacturer  thereof, and in compliance with all laws, rules and regulations of
every  governmental  authority having  jurisdiction over the Equipment or Lessee
and with the provisions of all policies of insurance  carried by Lessee pursuant
to Section 3.6.

                                       3
<PAGE>

         3.3    Delivery;   Installation;   Return;  Maintenance   and   Repair;
Inspection.  Lessee shall be solely responsible, at its own expense, for (a) the
delivery of the  Equipment to Lessee,  (b) the packing,  rigging and delivery of
the Equipment back to Lessor,  upon  expiration or termination of the Lease Term
(provided that Lessee has not exercised a purchase option,  if any, with respect
to such Equipment),  in good repair,  condition and working order, ordinary wear
and tear  excepted,  at the  location(s)  within the  continental  United States
specified by Lessor, and (c) the installation, de-installation,  maintenance and
repair of the  Equipment.  During the Lease Term,  Lessee  shall ensure that the
Equipment is covered by a maintenance agreement,  to the extent available,  with
the  manufacturer  of the  Equipment  or other party  reasonably  acceptable  to
Lessor.  Lessee  shall,  at its  expense,  keep the  Equipment  in good  repair,
condition  and  working  order,  ordinary  wear  and tear  excepted,  and at the
expiration  or  termination  of  the  Lease  Term  with  respect  to  any of the
Equipment,   have  such  Equipment   inspected  and  certified   acceptable  for
maintenance  service  by the  manufacturer.  If any of the  Equipment,  upon its
return to Lessor, is not in good repair,  condition and working order,  ordinary
wear  and  tear  excepted,  and so  inspected  and  certified,  Lessee  shall be
obligated to pay Lessor for the out-of-pocket expenses Lessor incurs in bringing
such  Equipment up to such status,  but not in excess of the Casualty  Value for
such  Equipment,  promptly  after its receipt of an invoice  for such  expenses.
Lessor shall be entitled to inspect the Equipment at reasonable times.

         3.4    Taxes. Lessee shall pay, and hereby indemnifies Lessor on a net,
after-tax  basis,  against,  and shall hold it harmless  from, all license fees,
assessments, and sales, use, property, excise and other taxes and charges, other
than those  measured by Lessor's net income,  now and  hereafter  imposed by any
governmental body or agency upon or with respect to any of the Equipment, or the
possession,   ownership,  use  or  operation  thereof,  or  any  Lease,  or  the
consummation of the transactions contemplated by any Lease.  Notwithstanding the
foregoing,  to the extent  required of it by applicable law and in reliance upon
Lessee's  disclosure  of the  location  of such  Equipment,  Lessor  shall  file
personal  property tax returns,  and shall pay personal  property  taxes payable
with respect to the Equipment. Lessee shall pay to Lessor the amount of all such
personal  property  taxes  within 15 days of its  receipt of an invoice for such
taxes.  For any  Lease  that is  specified  as an FMV  Lease  in the  applicable
Schedule,  Lessee  acknowledges that it is the intent of Lessor,  and a material
inducement  to Lessor to enter into such Lease,  to obtain all state and Federal
income tax benefits of ownership with respect to the Equipment under such Lease,
including entitlement to annual accelerated cost recovery deductions.

         3.5    Loss of Equipment.  Lessee assumes  the  risk  that,  and  shall
promptly  notify  Lessor in writing  if,  any item of  Equipment  becomes  lost,
stolen,  damaged,  destroyed or otherwise  unfit or unavailable for use from any
cause  whatsoever  (an "Event of Loss") after it has been  delivered to a common
carrier  for  shipment to Lessee.  Unless the item is damaged  and is  reparable
within a  reasonable  period of time in the  judgment  of Lessor (in which event
Lessee  shall  promptly  cause  such item to be  repaired  and  restored  to the
condition  and  value it had  prior to such  Event of Loss,  at its own cost and
expense), Lessee shall pay to Lessor on the Rent payment date following Lessor's
receipt of such  notice  (or,  if none,  30 days  after such Event of Loss),  an
amount  equal to the Rent  payment or payments  due and payable  with respect to
such Equipment on or prior to such date,  plus a sum equal to the Casualty Value
of such Equipment as of such date.  Upon making such payment,  the Rent for such
Equipment  shall  cease to  accrue,  the term of the Lease as to such  Equipment
shall terminate and (except in the case of loss,  unrecovered  theft or complete
destruction) Lessor shall be entitled to recover possession of such Equipment in

                                       4
<PAGE>

accordance  with the provisions of Section 3.3 above. If Lessor has received the
foregoing  amount,  Lessee  shall be entitled to the proceeds of any recovery in
respect of such  Equipment  from  insurance or  otherwise,  provided that if the
Equipment  is subject to an FMV Lease,  Lessee shall be entitled to receive such
proceeds only up to the Casualty Value therefor, any excess amount to be paid to
Lessor.

         3.6    Insurance.  Lessee shall obtain and maintain for the Lease  Term
at its own  expense,  property  damage and  liability  insurance  and  insurance
against loss or damage to the Equipment as a result of fire,  explosion,  theft,
vandalism  and such other risks of loss as are normally  maintained on equipment
of the type leased  hereunder  by  companies  carrying on the  business in which
Lessee is engaged, in such amounts, in such form and with such insurers as shall
be  satisfactory to Lessor.  Each insurance  policy shall name Lessee as insured
and Lessor and its assignees as additional  insureds and loss payees  thereof as
their  interest  may appear,  and shall  provide that it may not be cancelled or
altered  without at least 30 days' prior written  notice  thereof being given to
Lessor (or 10 days', in the event of non-payment of premium).

         3.7    Indemnity.  Except with  respect  to  the  gross  negligence  or
willful  misconduct of Lessor (and this exception includes cases in which Lessee
must  commence  an action  against  Lessor on  account  of a gross and  material
violation  of  Lessor's   obligations  under  this  Agreement),   Lessee  hereby
indemnifies,  protects,  defends and holds harmless  Lessor from and against any
and all claims,  liabilities (including negligence,  tort and strict liability),
demands,  actions, suits, and proceedings,  losses, costs, expenses and damages,
including reasonable attorneys' fees and costs (collectively, "Claims"), arising
out of, connected with, or resulting from any Lease or any of the Equipment,  or
any ancillary or related software or other intangibles,  whether arising before,
during or after the Lease  Term (but not  Claims  relating  to events  occurring
after Lessee has returned the Equipment to Lessor in accordance with Section 3.3
or after the Equipment has  otherwise  been removed from Lessee's  possession or
control by Lessor),  including  Claims relating to the  manufacture,  selection,
purchase,  delivery,  possession,  condition,  use,  operation,  return or other
disposition  of the  Equipment.  Each of the parties shall give the other prompt
written notice of any Claim of which it becomes aware.

         3.8    Prohibitions  Related to Lease and Equipment.  Without the prior
written  consent of Lessor,  which consent as it pertains to clauses (b) and (d)
below  shall  not be  unreasonably  withheld,  Lessee  shall  not:  (a)  assign,
transfer,  or  otherwise  dispose of any  Equipment,  the Lease or any rights or
obligations  thereunder;  (b)  sublease  any  of the  Equipment  or  permit  the
Equipment to be controlled by any other person;  (c) create or incur,  or permit
to exist, any security interest,  lien or encumbrance with respect to any of the
Equipment;  (d)  cause or  permit  any of the  Equipment  to be  moved  from the
location specified in the applicable Schedule; or (e) cause or permit any of the
Equipment to be moved outside the continental United States.

         3.9    Identification.   Lessee  shall  place  and  maintain  permanent
markings provided by Lessor on the Equipment evidencing ownership,  security and
other interests therein, as specified from time to time by Lessor.

         3.10   Alterations  and  Modifications.   Lessee  shall  not  make  any
additions, attachments, alterations or improvements to the Equipment without the
prior written consent of Lessor, not to be unreasonably  withheld. Any addition,
attachment,  alteration or improvement to any item of Equipment  shall belong to

                                       5
<PAGE>

and  become the  property  of Lessor  unless,  at the  request of Lessor,  it is
removed prior to the return of such item of Equipment by Lessee. Lessee shall be
responsible  for all costs  relating to such removal and shall restore such item
of Equipment to the condition and value otherwise required hereunder.

         3.11   Personal Property.  Lessee acknowledges  and represents that the
Equipment shall be and remain personal property,  notwithstanding  the manner by
which it may be attached or affixed to realty,  and Lessee shall do all acts and
enter  into all  agreements  necessary  to  ensure  that the  Equipment  remains
personal property. If reasonably requested by Lessor with respect to any item of
Equipment, Lessee shall obtain and deliver to Lessor equipment access agreements
or like  protections,  reasonably  satisfactory  to  Lessor,  from  all  persons
claiming  any  interest in the real  property on which such item of Equipment is
installed or located.

         3.12   Financial Statements. Lessee shall promptly  furnish  to  Lessor
such  financial or other  statements  regarding the condition and  operations of
Lessee and any guarantor of any Lease, and information  regarding the Equipment,
as Lessor may from time to time  reasonably  request,  provided,  however,  that
Lessee has no obligation to furnish  financial  information where the release of
such  information  would  violate or be  reasonably  likely to violate  state or
federal  securities  laws or applicable  regulations of any stock exchange where
Lessee's securities are listed.

         3.13   Lessee Representations.  Lessee  hereby  represents  that,  with
respect to this Agreement, and each Schedule,  certificate evidencing acceptance
of equipment,  assignment of purchase order, insurance letter,  proposal letter,
UCC financing  statement,  or other document now or hereafter executed by Lessee
in  connection  with  any  Lease  (collectively,  "Lease  Documents"):  (a)  the
execution,  delivery and performance  thereof by Lessee or its  attorney-in-fact
have been duly  authorized by all necessary  corporate,  partnership  or company
action; (b) the person executing such documents is duly authorized to do so; and
(c) such documents  constitute legal,  valid and binding  obligations of Lessee,
enforceable in accordance with their terms.

                             4. DEFAULT AND REMEDIES
                               ---------------------

         4.1    Events of Default.  The occurrence of any of the following shall
constitute  an "Event of Default"  hereunder  and under each  Lease:  (a) Lessee
fails to pay any Rent or other  amount due under any Lease within ten days after
it becomes due and payable; (b) any representation or warranty of Lessee made in
any Lease  Document  proves to have been  false or  misleading  in any  material
respect as of the date when it was made; (c) Lessee fails to maintain  insurance
as required  herein or breaches  any of clauses  (a), (b) or (e) of Section 3.8;
(d) Lessee fails to perform any other material covenant,  condition or agreement
made by it  under  any  Lease,  and such  failure  continues  for 20  days;  (e)
bankruptcy, receivership, insolvency,  reorganization,  dissolution, liquidation
or other similar  proceedings are instituted by or against Lessee, any guarantor
of any Lease or any partner of a partnership Lessee or guarantor,  or all or any
part of such person's  property,  under the Federal Bankruptcy Code or other law
of the  United  States  or of any other  competent  jurisdiction,  and,  if such
proceeding is brought against such person, it consents thereto or fails to cause
the  same to be  discharged  within  45  days  after  it is  filed;  (f)  Lessee
materially  defaults  under  any  agreement  with  respect  to the  purchase  or
installation  of any of the  Equipment;  or (g) Lessee or any  guarantor  of any
Lease, or any of their  respective  subsidiaries or other  affiliates,  defaults

                                       6
<PAGE>

under any other  material  instrument or agreement with Lessor or Cisco Systems,
Inc.

         4.2    Remedies.  If an Event of Default  exists,  Lessor may  exercise
any one or more of the  following  remedies,  in addition to those arising under
applicable law: (a) proceed, by appropriate court action, to enforce performance
by Lessee of the applicable covenants of any or all of the Leases; (b) terminate
any or all Leases by notice to Lessee and take  possession  of any or all of the
Equipment and, for such purpose (and to the extent permitted by applicable law),
enter upon any premises where the Equipment is located with or without notice or
process of law and free from all claims by Lessee, or require Lessee to assemble
the  Equipment  and deliver it to Lessor in  accordance  with  Section  3.3; (c)
recover any and all direct and  incidental  damages,  including  all accrued and
unpaid Rent and other amounts owing under any Lease,  and (i) for any Lease that
is an FMV Lease,  the Equipment for which has not been returned to Lessor in the
condition required hereunder,  an amount equal to the Casualty Value thereof; or
(ii) for any Lease that is an FMV  Lease,  the  Equipment  for which has been so
returned to Lessor,  such  amounts as are  provided  for the lessee  breach of a
personal  property lease under the Uniform  Commercial Code of the  jurisdiction
specified in Section  5.11 (the  "Code"),  using the Discount  Rate to calculate
present  values  for such  purpose;  or (iii) for any  Lease  that is not an FMV
Lease, an amount equal to the present value, discounted at the Discount Rate, of
the sum of all Rent and other  payments  remaining  to be paid  under such Lease
through the Lease Term plus the applicable  purchase option amount  specified in
Paragraph  7 of  the  Schedule;  and  (d)  sell  or  re-lease  any or all of the
Equipment,  through public or private sale or lease transactions,  and apply the
proceeds  thereof to Lessee's  obligations  under such Leases or otherwise  seek
recovery in accordance  with  applicable  provisions  of the Code.  Lessee shall
remain liable for any resulting  deficiency and Lessor may retain any surplus it
may realize in connection  with an FMV Lease.  The "Discount  Rate" shall be the
rate for U.S. Treasury  obligations  having a constant maturity of three months,
as specified in the Federal  Reserve  Statistical  Release H.15 (or  replacement
publication) issued most recently prior to the date of termination of the Lease.
Lessee shall pay all costs and expenses (including  reasonable  attorneys' fees)
reasonably incurred by Lessor in retaking possession of, and removing,  storing,
repairing,  refurbishing and selling or leasing such Equipment and enforcing any
obligations of Lessee pursuant to any Lease.

                                5. MISCELLANEOUS
                                   -------------

         5.1    Performance of Lessee's  Obligations.  Upon Lessee's failure  to
pay any amount or perform any obligation  under any Lease when due, Lessor shall
have the right,  but shall not be  obligated,  to pay such sum or  perform  such
obligation,  whereupon such sum or cost of such  performance  shall  immediately
become due and payable  thereunder,  with  interest  thereon at the Default Rate
from the date such payment or performance was made.

         5.2    Right to Use. So long as no Event  of  Default  exists,  neither
Lessor nor its assignee shall interfere with Lessee's right to use the Equipment
under any Lease.

         5.3    Assignment by Lessor.   Lessor may assign or transfer any or all
of Lessor's  interest in this Agreement,  any Lease, any Equipment or Rents that
does not purport to change the substantive terms of this Agreement or any Lease,
without  notice to Lessee.  Any assignee of Lessor shall have all of the rights,
but  none  of the  obligations  (unless  otherwise  provided  in the  applicable
assignment),  of a  "Lessor"  under  this  Agreement  and the  applicable  Lease

                                       7
<PAGE>

(except,  however,  that any  assignee  of the Lessor  will  assume  obligations
relating   entirely  to   transactions   under  each  Lease  which  occur  after
assignment),  and Lessee agrees that it will not assert against any assignee any
defense,  counterclaim  or offset  that  Lessee may have  against  Lessor or any
preceding assignee, and that upon notice of such assignment or transfer, it will
pay all Rent and other sums due under this Agreement and the applicable Lease to
such assignee or transferee. Lessee acknowledges that any assignment or transfer
by Lessor shall not materially  change Lessee's duties or obligations under this
Agreement or any Lease, nor materially  increase the burdens or risks imposed on
Lessee.

         5.4    Further  Assurances.  Upon the request of Lessor  from  time  to
time,  Lessee  shall  execute and deliver  such  further  documents  and do such
further acts as Lessor may be  reasonably  required or  appropriate  to fully to
effect the  purposes of this  Agreement  or any Lease.  Lessee  hereby  appoints
Lessor its attorney in fact, coupled with an interest,  authorized,  without any
obligation  to do so,  (a) to sign on  Lessee's  behalf  and  file,  record  and
register financing statements, and amendments and continuations thereof, and any
other  documents  relating to liens,  security  interests or property  rights of
Lessor or Lessee  with  respect to any  Equipment  and  ancillary  property,  in
accordance with any Uniform  Commercial Code or other code or statute  (provided
that such "other  documents"  must be reasonably  necessary to protect  Lessor's
contract  expectancies under the Lease), and (b) to enforce,  in its own name or
in the name of  Lessee,  claims  relating  to any  Equipment  against  insurers,
manufacturers  or other persons,  and to make,  adjust,  settle,  compromise and
receive  payments as to such  claims.  Upon request of Lessee from time to time,
Lessor shall respond to reasonable  requests for information  from Lessee or its
auditors  concerning  outstanding  or  terminated  Leases with Lessee,  and will
prepare and sign such documents relating to this Agreement to the extent that it
is otherwise  lawfully  obligated to do so (including,  but not limited to UCC-3
Termination  Statements  relating  to  specific  Leases  after  Lessee has fully
performed  all its  obligations  under such  Leases),  provided,  however,  that
Lessor's failure to fully or timely perform its obligations  hereunder shall not
be deemed to be a material  breach of its  obligations  under this  Agreement or
under any Lease.

         5.5    Rights and Remedies.  Each right and remedy  granted  under  any
Lease shall be cumulative and in addition to any other right or remedy  existing
in equity, at law, by virtue of statute or otherwise,  and may be exercised from
time to time concurrently or independently and as often and in such order as the
enforcing  party  may  elect.  Any  failure  or delay on the part of  Lessor  in
exercising any such right or remedy shall not operate as a waiver thereof.

         5.6    Notices. Any  notice,  request,  demand,  consent,  approval  or
other communication  provided for or permitted in relation to any Lease shall be
in writing  and shall be  conclusively  deemed to have been  received by a party
hereto on the day it is delivered  to such party at its address,  or received by
the party at such  facsimile  number,  as is set forth in such Lease (or at such
other  addresses or fax numbers  such party shall  specify to the other party in
writing),  or if sent by registered or certified mail, return receipt requested,
on the fifth day after the day on which it is mailed, postage prepaid, addressed
to such party.

         5.7    Section Headings; Interpretation. Section headings are  inserted
for  convenience  of  reference  only and shall not affect any  construction  or
interpretation  of any Lease  Document.  In  interpreting  the provisions of any
Lease  Document,  (a) the term  "including"  is not limiting;  (b) references to
"person" include individuals, corporations and other legal persons and entities;
(c) the singular of defined terms  includes the plural and  vice-versa;  and (d)

                                       8
<PAGE>

section and  paragraph  references  are to the document in which such  reference
appears, unless the context otherwise requires.

         5.8    Entire Lease.  This Agreement,  together  with the  other  Lease
Documents,  constitute  the entire  agreement  between  Lessor  and Lessee  with
respect to the lease of the Equipment. No waiver or amendment of, or any consent
with  respect to, any  provision of any Lease  Document  shall bind either party
unless set forth in a writing,  specifying such waiver,  consent,  or amendment,
signed by both  parties.  TO THE  EXTENT  PERMITTED  BY  APPLICABLE  LAW AND NOT
OTHERWISE  SPECIFICALLY  GRANTED TO LESSEE IN ANY LEASE DOCUMENT,  LESSEE HEREBY
WAIVES ANY AND ALL RIGHTS OR REMEDIES  CONFERRED UPON A LESSEE UNDER THE CODE OR
ANY OTHER APPLICABLE LAW OR STATUTE,  WITH RESPECT TO A NON-MATERIAL  DEFAULT BY
LESSOR  UNDER THIS  AGREEMENT  OR ANY LEASE.  Each FMV Lease is  intended by the
parties as a "finance lease" under the Code.

         5.9    Severability.  Should any  provision  of any Lease  Document  be
or become invalid,  illegal,  or  unenforceable  under applicable law, the other
provisions of such Lease Document shall not be affected and shall remain in full
force and effect.

         5.10   Attorneys' Fees;  Default Interest; Maximum Rates.  Lessee shall
reimburse Lessor for all reasonable and verifiable charges,  costs, expenses and
attorney's fees reasonably incurred by Lessor (a) in defending or protecting its
interests in the  Equipment,  (b) in the  enforcement  of this  Agreement or any
Lease,  and (c) in any lawsuit or other legal proceeding to which this Agreement
or any Lease gives rise. However, that Lessee has no reimbursement obligation in
the event that (w) Lessee is not in default under the Agreement,  (x) Lessor has
materially  breached  this  Agreement or any Lease,  (y) Lessee has  commenced a
proceeding  against Lessor (which  proceeding is not commenced as a counterclaim
or affirmative defense in response to a proceeding commenced by any Lessor), and
(z) Lessee  prevails in its claim against Lessor  ("prevails"  means that Lessee
has  been  awarded  all  or  substantially  all  of  the  relief  sought  in its
proceeding). Also, Lessee has no reimbursement obligation for the attorneys fees
and costs expended in the  negotiation  and preparation of this Agreement or any
Schedule or related  documents.  Any  nonpayment of Rent or other amount payable
under any Lease shall  result in Lessee's  obligation  to promptly pay Lessor on
such  overdue  payment,  for the  period  of time  during  which  it is  overdue
(including  during any grace period),  interest at a rate ("Default Rate") equal
to fourteen  percent (14%) per annum. To the extent that any payment of interest
(including  any amount deemed imputed  interest for purposes of applicable  law)
under any Lease Document would otherwise  exceed  provisions of any law limiting
the highest rate of interest  that may be lawfully  contracted  for,  charged or
received by Lessor,  such payment  amount shall be deemed reduced to such amount
as is equal to or consistent with the highest rate permitted by applicable law.

         5.11   Governing Law and Jurisdiction.  THIS AGREEMENT  AND  THE  OTHER
LEASE  DOCUMENTS  SHALL BE GOVERNED IN ALL  RESPECTS BY THE LAWS OF THE STATE OF
CALIFORNIA.  LESSOR  AND  LESSEE  WAIVE  ALL  RIGHTS  TO  TRIAL  BY  JURY IN ANY
LITIGATION ARISING FROM ANY LEASE DOCUMENT. LESSEE CONSENTS TO THE NON-EXCLUSIVE

                                       9
<PAGE>

JURISDICTION  OF THE STATE  COURTS AND THE  FEDERAL  COURTS  LOCATED IN NEW YORK
CITY, NEW YORK, FOR THE RESOLUTION OF ANY DISPUTES UNDER ANY LEASE DOCUMENT.

         5.12   Survival.  All obligations  of Lessee to make payments to Lessor
under any Lease or to indemnify Lessor, including pursuant to Section 3.4 or 3.7
above,  with respect to a Lease, and all rights of Lessor hereunder with respect
to a Lease,  shall survive the  termination  of such Lease and the return of the
Equipment.

         5.13   Security. To secure the payment and performance by Lessee of all
obligations under each Lease, Lessee hereby grants Lessor a security interest in
Lessee's right, title and interest,  now existing and hereafter arising,  in and
to, (a) all Equipment subject to such Lease, (b) all insurance, warranty, rental
and other  claims and rights to payment  and chattel  paper  arising out of such
Equipment, and (c) all books, records and proceeds relating to the foregoing.

         5.14   Counterparts; Chattel Paper. Each Lease Document may be executed
in counterparts,  and when so executed each counterpart shall be deemed to be an
original,  and such  counterparts  together  shall  constitute  one and the same
instrument.  The original of each Schedule  shall  constitute  chattel paper for
purposes of the Code. If there exist multiple  originals of a Schedule,  the one
marked  "Lessor's  Copy" or words of similar  import,  shall be the only chattel
paper.

         5.15   Appendix.  Any lease Appendix  executed  by  Lessor  and  Lessee
making  reference  to this  Agreement  is a part of and  incorporated  into this
Agreement by this reference.

         5.16   No Obligation to  Purchase  or  Lease  Equipment;  Non-Exclusive
Relationship.  Nothing in this Agreement shall impose upon Lessee any obligation
to purchase or lease any equipment from Vendor, Lessor or any other person prior
to its execution of a Purchase  Order.  Also,  nothing in this  Agreement  shall
impose upon Lessor any  obligation  to either  enter into any lease  transaction
prior to its  delivery  of a Schedule  or to  prepare  or deliver a Schedule  to
Lessee when  presented  with a Purchase  Order (whether in draft or final form).
Lessee's relationship with Lessor is non-exclusive, and provided that Lessee has
not  agreed or deemed to have  agreed  to enter  into a lease  transaction  with
Lessor or to otherwise execute a Schedule,  Lessee is free to purchase equipment
subject to such  Purchase  Order  without  leasing  it from  Lessor or any other
party.

Dear Charles,

Cisco Systems Capital  Corporation  ("CSC"),  a wholly owned subsidiary of Cisco
Systems,  Inc.,  specializes in providing innovative finance solutions for Cisco
Systems  products  and  services.  We  are  pleased  to  present  this  proposal
("Proposal") for the transaction described below:

LESSOR:                  Cisco Systems Capital Corporation

LESSEE:                  VDC Telecommunications, Inc. ("VDC")

GUARANTOR:               VDC Communications, Inc.

EQUIPMENT:               Cisco Systems Products, as presented by Nick Shkreli

MAXIMUM EQUIPMENT COSTS: In the aggregate, up to $1,000,000, including softcosts
                         (not to exceed 10%)

SHIP TO:                 The  equipment  may be shipped to or used in  locations
                         within  the  U.S. as advised by VDC and those locations
                         outside the US as may be approved by CSC. In connection
                         with  any  equipment to be  placed  outside  the  U.S.,
                         Lessee shall assume responsibility for  all  applicable
                         withholding  taxes,  value-added   taxes,  duties   and
                         compliance   with  all  other  U.S.  and  foreign  laws
                         relating to the sale, leasing, delivery, export, import
                         or use of the equipment outside the U.S.

PARTIAL SHIPMENTS:       Please indicate at the bottom of  this  letter  whether
                         Lessee will accept scheduling of partial purchase order
                         shipments.  (If not,  please  note  that  Cisco Systems
                         will retain shipments until complete.)

ORIGINAL TERM:           36 months

RENTAL FACTOR:           The rental amount,  expressed  as a percentage  of  net
                         equipment   cost   after  Advance  Payment,  "Equipment
                         Cost"), is Months 1-6 (Lease Rate Factor of  .0095833);
                         Months 7-36 (Lease Rate Factor of .03815).   The Rental
                         factor shall also apply to  softcosts  and software.

PERIODIC RENT PAYMENT:   In  accordance  with  the  pricing  and   configuration
                         referenced  above,  the  rent payment for  each  Rental
                         Period ("Rent") on the lease would be the net Equipment
                         Cost multiplied by the Lease Rate Factor.

ADVANCE PAYMENTS:        20% of  equipment  cost  with   signed   schedule,  but
                         deemed  acceptance  of the equipment will take place 30
                         days after shipment of the final piece of equipment per
                         schedule.  There is no interim rent,  and  commencement
                         will take place according to the date referenced above.

SOFT COSTS:              "Soft Costs," such  as  shipping,  taxes,  maintenance,
                         installation, cabling, may be included in  or  financed
                         by the lease, as approved by CSC in   its   discretion.
                         Assuming  that Soft  Costs make up less than 10% of the
                         total  Equipment Cost, Soft Costs will be  included  at
                         the above  Lease  Rate Factor.

                         Notwithstanding  the  foregoing, CSC is not responsible
                         for   maintenance,   software   or   ancillary services
                         relating to the equipment, nor for ensuring   that  any
                         necessary   maintenance   or   services  agreements  or
                         software licenses with Cisco Systems or any other third
                         party are in effect at any time.

                                                                          Page 2

NET LEASE:               This is a net lease  transaction under which  all costs
                         and  liabilities,  including  without  limitation,  for
                         insurance, maintenance  and taxes,  are paid by  Lessee
                         for the term of the lease. Transferable  manufacturer's
                         guarantees or  warranties  will be passed on to Lessee.
ADJUSTMENT OF
RENTAL FACTORS:          The  rental  amount  quoted  in  this  Proposal will be
                         adjusted  prior  to  the  date  of  preparation of  any
                         Equipment Lease Schedule to reflect changes equal to or
                         greater than one quarter of one percent (.25%)  in  the
                         weekly average of the Three Year Treasury Note interest
                         rate,  as  specified  in  Federal  Reserve  statistical
                         release H.15 from the week preceding the date  of  this
                         Proposal to the week  preceding the date of preparation
                         of the Schedule.  Changes to the benchmark rate of less
                         than one quarter of one  percent (.25%) will not affect
                         the Lease Rate Factor quoted  herein.  The  Three  Year
                         Treasury Note H.15  statistic is updated  weekly by the
                         U.S. Federal Reserve for the preceding  week's  average
                         yield.  The statistic  is  publicly  available  on  the
                         Internet at http://www.bog.frb.fed.us/ releases/h15/.

EQUIPMENT PROCUREMENT:   Purchase orders for equipment shall be placed by Lessee
                         with Cisco  Systems,  Inc.,  or  a  Cisco  Value  Added
                         Reseller,  with all  rights  assigned  to  Lessor  upon
                         Lessor's election to fund.  All  such  purchase  orders
                         shall be subject to the  standard  Terms and Conditions
                         of Sale of Cisco  Systems,  Inc.  or  such Cisco  Value
                         Added  Reseller,   including the "net 30" payment terms
                         commencing from date  of  shipment.  No  funding  shall
                         occur prior  to  execution  by  the  parties  of  CSC's
                         standard  Master Agreement to Lease Equipment  ("Master
                         Lease Agreement").  If, for any reason, Lessor does not
                         fund any equipment or lease, or any contemplated  lease
                         is otherwise not consummated, Lessee  shall  be  solely
                         responsible  for payment in full of the purchase  price
                         (together with ancillary costs and expenses) associated
                         with any outstanding orders executed by Lessee.

INVOICING:               A single invoice will be furnished  monthly,  detailing
                         all Lease Schedules and rental  payments  due.  Freight
                         charges will be added to CSC's  invoice  and  billed to
                         lessee with the first rental payment.

END OF LEASE OPTION:     At the end  of  the Original Term  of the Lease, Lessee
                         may purchase the equipment for $1.

UTILIZATION PERIOD:      All Purchase Orders for equipment under this   proposal
                         shall be submitted no later than 90 days from the  date
                         of acceptance.

DOCUMENTATION FEE:       None

OTHER FEES:              None

EXPIRATION DATE:         This  Proposal  shall  terminate  30  days from today's
                         date, unless accepted.

CREDIT APPROVAL:         This Proposal includes only a brief description  of the
                         substantive terms and conditions  of  the  contemplated
                         lease transactions and is  not  intended  as  a  formal
                         commitment  of  credit  by  CSC  or  Cisco Systems or a
                         formal commitment by VDC. Any funding  by CSC  for  the
                         purchase of equipment is subject to the ongoing  credit
                         approval of CSC (including the absence of any  material
                         adverse change, in the judgment of CSC, in the business
                         or financial condition or prospects of Lessee)  and  to
                         satisfactory  documentation   including   as  described
                         below.   You   agree  to  provide  two  years'  audited
                         financial  statements,  bank  references,  a  completed
                         credit  application  and  any  other  required   credit

                                    GUARANTY


THIS GUARANTY is executed as of February 22, 2000, by VDC Communications, Inc. a
Delaware  corporation  ("Guarantor")  to and for the  benefit  of CISCO  SYSTEMS
CAPITAL CORPORATION, a Nevada corporation ("Lessor").

WHEREAS  Guarantor  desires  that  VDC  Telecommunications,   Inc.,  a  Delaware
corporation  ("Lessee"),  pursuant  to a Master  Agreement  to  Lease  Equipment
("Master  Agreement"),  dated as of February 22, 2000 between Lessor and Lessee,
enter into one or more  leases of personal  property in the form of  Schedule(s)
thereto (collectively, the "Lease"); and

WHEREAS as a condition to entering into the Lease,  Lessor requires that all the
obligations of Lessee under the Lease be guaranteed by Guarantor;

NOW,  THEREFORE,  in order to induce  Lessor to enter into the Lease,  Guarantor
hereby agrees as follows:

1.     Guarantor  does hereby  acknowledge  that it is fully aware of  the terms
       and   conditions   of  the    Lease  and   does  hereby  irrevocably  and
       unconditionally guarantee, as primary obligor and not as a surety merely,
       without offset or deduction,  the due and  punctual  payment  when due by
       Lessee of all Rent (as defined in the Lease)  which may from time to time
       become due and payable in accordance  with the terms of the Lease and the
       performance by Lessee of all  of  its  other  obligations under the Lease
       (the payment of Rent and  each  other  obligation  of  Lessee  guaranteed
       hereby being hereinafter referred to as an "Obligation" and  collectively
       as the "Obligations"). Guarantor does hereby agree that in the event that
       Lessee fails to perform  any  Obligation  for any reason,  Guarantor will
       perform or otherwise provide  for and bring about  promptly  when due the
       performance  of  each such Obligation.  This Guaranty  of the Obligations
       shall constitute a  guaranty  of  payment  and  performance  and  not  of
       collection.  Guarantor specifically agrees that it shall not be necessary
       or required, and that  Guarantor  shall not be entitled to require,  that
       Lessor (a) file suit or proceed  to obtain or assert a claim for personal
       judgment against Lessee or any other person for any  Obligation, (b) make
       any effort at collection or other enforcement of any  Obligation  from or
       against Lessee or any  other  person,  (c)  foreclose  against or seek to
       realize  upon any security now or hereafter  existing for any  Obligation
       or upon any  balance of any  deposit  account or  credit  on the books of
       Lessor or any other person  in favor of  Lessee or any other  person, (d)
       exercise or assert any other right or remedy to whic  Lessor is or may be
       entitled in connection  with  any  Obligation  or any  security  or other
       guaranty therefor, or (e) assert or file any claim  against the assets of
       Lessee  or any other guarantor of other person liable for any Obligation,
       or any part thereof, before or as a condition of enforcing the  liability
       of Guarantor under this Guaranty or requiring payment or  performance  of
       any Obligation by Guarantor hereunder, or at any time thereafter.

2.     Guarantor  waives  notice of the  acceptance  of this Guaranty and of the
       performance  or  nonperformance  by Lessee,  presentment to or demand for
       payment or other  performance  from Lessee or any other person and notice
       of  nonpayment  or  failure  to  perform  on  the  part  of  Lessee.  The
       obligations of Guarantor  hereunder  shall be absolute and  unconditional
       and shall remain in full force and effect and shall not be subject to any
       reduction, limitation, impairment or termination for any reason.

3.     No right,  power or remedy herein conferred upon or reserved to Lessor is
       intended to be exclusive of any other right,  power or remedy or remedies
       and each and every  right,  power and remedy of Lessor  pursuant  to this
       Guaranty now or  hereafter  existing at law or in equity or by statute or
       otherwise  shall,  to the extent  permitted  by law,  be  cumulative  and
       concurrent and shall be in addition to each other right,  power or remedy
       pursuant to this  Guaranty,  and the exercise by Lessor of anyone or more
       of such rights, powers or remedies shall not preclude the simultaneous or
       later  exercise  by Lessor  of any or all such  other  rights,  powers or
       remedies.

4.     No failure or delay by Lessor to insist  upon the strict  performance  of
       any  term,  condition,  covenant  or  agreement  of this  Guaranty  or to
       exercise any right, power or remedy hereunder or consequent upon a breach
       hereof shall constitute a waiver of any such term,  condition,  covenant,
       agreement,  right,  power or remedy or of any such  breach,  or  preclude
       Lessor from exercising any such right,  power or remedy at any later time
       or times.

5.     In case  any one or more of the  provisions  contained  in this  Guaranty
       should be invalid, illegal or unenforceable in any respect, the validity,
       legality and enforceability of the remaining  provisions contained herein
       shall not in any way be affected or impaired thereby.

6.     This Guaranty (a)  constitutes the entire  agreement,  and supersedes all
       prior agreements and understandings, both written and oral, among Lessee,
       Lessor and Guarantor with respect to the subject  matter hereof,  (b) may
       be  executed  in several  counterparts,  each of which shall be deemed an
       original,  but all of which  together  shall  constitute one and the same
       instrument,  and (c) shall be binding upon  Guarantor and its  successors
       and assigns  and shall inure to the benefit of, and shall be  enforceable
       by, Lessor and its successors and assigns.

7.     Unless otherwise specifically provided herein, all notices, instructions,
       requests and other  communications  required or permitted hereunder shall
       be in writing and shall become  effective when received or if mailed when
       deposited  in the United  States mail,  postage  prepaid,  registered  or
       certified mail,  return receipt  requested.  Notices shall be directed to
       Lessor at its address  set forth in the Lease,  and to  Guarantor  at its
       address set forth below,  or at such other address as such party may from
       time to time furnish to the other by notice similarly given.

8.     This Guaranty shall be governed by, and construed in accordance with, the
       laws of the State of California.


IN WITNESS WHEREOF, Guarantor has caused this Guaranty to be duly executed as of
the date first hereinabove set forth.

SECTION 1. CUSTOMER ORDERS
- --------------------------

1.1   Submission of Customer Orders. To order any Service,  Customer may  submit
      ------------------------------
to Level 3 an order  form for  Services,  completed  with  Level 3's  assistance
("Customer Order") requesting the provision of Service.  Level 3's delivery of a
Target  Install  Date  respecting  such  Service  shall   constitute  Level  3's
acceptance of the Customer Order. The Customer Order and its backup detail shall
set forth the Service,  the Premises and/or Space,  the prices to be charged for
Services and any applicable term and/or Revenue Commitment.

1.2   Undertaking of Level 3. If Level 3 issues a Target Install Date respecting
      -----------------------
Services,  Level 3 will furnish such Services in  accordance  with the Terms and
Conditions and any Customer Orders.

SECTION 2. BILLING AND PAYMENT
- ------------------------------
                                  Page 1 of 27
<PAGE>

2.1   Payment of Bills.  Level 3 bills all charges  incurred  by  Customer  on a
      -----------------
monthly basis.  Level 3 bills in advance for all Services to be provided  during
the  upcoming  month,  except  for  charges  which are  dependent  upon usage of
Service,  which are  billed in  arrears.  Billing  for  partial  months  will be
prorated based on a calendar month.  All bills are due upon receipt,  and become
past due ten (10) days later.  The unpaid  balance of any past due balance which
is not  reasonably  disputed  under  Section 2.4 hereof shall bear interest at a
rate of 1.5% per month  (prorated  on a daily  basis  beginning  on the past due
date), or the highest rate allowed by law, whichever is less.

To the extent  Customer  orders any service  designated as "Burstable"  (defined
below), the following billing method shall apply: Customer will be billed as set
forth  above  for its  Committed  Data  Rate.  In  addition,  over  each  month,
Customer's  usage of the  Service  will be  sampled  by  Level 3 in five  minute
inbound and outbound  averages.  At the end of the month, the top ten percent of
the  inbound  and  outbound  averages  shall be  discarded.  The  highest of the
resulting ninetieth percentile for inbound and outbound traffic will be compared
to the Committed  Data Rate. If the  ninetieth  percentile of either  inbound or
outbound  traffic is higher than the  Committed  Data Rate,  Customer  will,  in
addition  to being  billed  for its  Committed  Data  Rate,  be  billed  for its
utilization of the Service that exceeds their  Committed Data Rate,  which shall
be billed at the contracted-for  price per Mbps. Burstable shall mean Customer's
ability to use Services above and beyond a stated Committed Data Rate.

In the event the Services ordered by Customer involve a local loop, Customer may
arrange,  through a local exchange carrier colocated in Level 3's gateway Space,
for its own local loop,  or it may have Level 3 provide  the same.  In the event
Customer  provides for its own local loop,  Customer must provide to Level 3 all
circuit facility assignment  information,  firm order commitment information and
the design  layout  records  necessary to enable  Level 3 to make the  necessary
cross-connection  between the Services and Customer's  designated local exchange
carrier.  Level 3 may charge Customer a non-recurring  cross-connect fee to make
such connection,  and an additional  non-recurring charge may apply in the event
that  Customer  requests  and Level 3 permits  Customer  to change  its  Service
installation  date. In the event Customer provides for its own local loop, Level
3's billing for the Services  will commence once it has installed and tested the
Services up to the Level 3 side of the cross-connect circuit.  Otherwise,  Level
3's billing for the Services  will  commence once the Services are installed and
tested.

2.2   Taxes and  Fees. Except for  taxes  based on Level 3's net  income  and ad
      ----------------
valorem,  personal  and real  property  taxes  imposed  on Level  3's  property,
Customer shall be  responsible  for payment of all sales,  use, gross  receipts,
excise, access, bypass, franchise or other local, state and federal taxes, fees,
charges,  or  surcharges,  however  designated,  imposed  on or  based  upon the
provision, sale or use of the Services.

2.3   Regulatory  and  Legal Changes.   In the event of any change in applicable
      -------------------------------
law, regulation,  decision, rule or order that materially increases the costs or
other  terms of delivery of Service,  Level 3 and  Customer  agree to  negotiate
regarding  the rates to be charged to Customer to reflect such  increase in cost
and, in the event that the parties are unable to reach agreement  respecting new
rates  within  thirty  (30) days after  Level 3's  delivery  of  written  notice
requesting renegotiation, then (a) Level 3 may pass such increased costs through
to Customer,  and (b) Customer may terminate the affected Customer Order without
termination liability upon sixty (60) days' prior written notice.

2.4   Disputed Bills. In the event that Customer disputes any portion of a Level
      ---------------
3 bill,  Customer  must pay the  undisputed  portion  of the  bill and  submit a
written claim for the disputed  amount.  All claims must be submitted to Level 3
within  sixty  (60) days of  receipt of  billing  for those  Services.  Customer
acknowledges that it is able to and that it is reasonable to require Customer to
dispute  bills  within that time,  and  Customer  therefore  waives the right to
dispute charges not disputed within the time frame set forth above.

2.5   Credit Approval and Deposits.  Customer  shall provide Level 3 with credit
      -----------------------------
information as requested, and delivery of Service is subject to credit approval.
Level 3 may require Customer to make a deposit (which will not exceed Customer's
estimated  charges  for  two  months'  Service)  as a  condition  to  Level  3's
acceptance of any Customer Order, or as a condition to Level 3's continuation of
Service,  which  deposit  shall be held by Level 3 as  security  for  payment of
Customer's  charges.  At such time as the  provision  of Service to  Customer is
terminated, the amount of the deposit will be credited to Customer's account and
any credit balance which may remain will be refunded.

2.6   Fraudulent Use of  Services.  Customer  is  responsible  for  all  charges
      ----------------------------

                                  Page 2 of 27
<PAGE>
attributable to Customer incurred  respecting the Services,  even if incurred as
the result of fraudulent or unauthorized use of the Services, unless Level 3 has
actual knowledge of the same and fails to notify Customer thereof.  Level 3 may,
but is not  obligated  to, detect or report  unauthorized  or fraudulent  use of
Services.

SECTION 3. DISCONTINUANCE OF CUSTOMER ORDERS
- --------------------------------------------

3.1   Discontinuance of  Customer  Order by Level 3. Level 3 may  terminate  any
      ----------------------------------------------
Customer Order and discontinue  Service without liability:
A. If Customer fails to pay a past due balance for  Services:  (i)  usage  based
and billed in arrears,  provided  the same is not paid within  three (3) days of
written  notice  thereof  provided  by Level 3; or (ii) flat rated and billed in
advance,  provided the same is not paid within seven (7) days of written  notice
thereof provided by Level 3;
B. If Customer  violates any law, rule,  regulation or policy of any  government
authority having  jurisdiction  over the Services;  if Customer makes a material
misrepresentation  in any submission of information in a Customer Order or other
submission of information to Level 3; if Customer  engages in any fraudulent use
of the Services; or if a court or other government authority having jurisdiction
over the Services prohibits Level 3 from furnishing the Services;
C. If  Customer  fails to cure its breach of any  provision  of these  Terms and
Conditions or any Customer  Order within thirty (30) days written notice thereof
provided by Level 3;
D. If Customer files bankruptcy,  for  reorganization,  or fails to discharge an
involuntary petition therefore within sixty (60) days;
E. If Customer's use of the Services materially exceeds Customer's credit limit,
unless  within  fourteen (14) days written  notice  thereof by Level 3, Customer
provides adequate security for payment for the Services.

3.2   Effect of  Discontinuance.  Upon Level 3's  discontinuance  of  Service to
      --------------------------
Customer,  Level 3 may, in addition to all other  remedies that may be available
to Level 3 at law or in equity,  assess and collect from Customer any applicable
termination charge.

3.3   Resumption of  Service.  If Service has been  discontinued  by Level 3 and
      -----------------------
Customer  requests  that  Service be  restored,  Level 3 shall have the sole and
absolute  discretion to restore such  Service.  Nonrecurring  charges,  with the
exception of any charges for the build-out of  Colocation  Space already paid by
Customer, may apply to restoration of Service.

3.4   Discontinuance of Customer Order by Customer.
      ---------------------------------------------
A. Customer shall have the right to terminate and discontinue  affected  Service
- --
prior to the end of the agreed term with  respect to which a Customer  Order has
been  executed  respecting  such  Service  without  payment  of  any  applicable
termination charge if: (i) such Service is Unavailable (as defined below) on two
or more separate  occasions of more than eight (8) hours each in any thirty (30)

repair any damage to the Facilities  caused thereby;  and (2) be responsible for
the payment of service  charges in the event that  maintenance  or inspection of

                         ADDITIONAL TERMS AND CONDITIONS
                            FOR PRIVATE LINE SERVICE

The following additional terms and conditions are applicable where,  pursuant to
a Customer Order, Customer orders metropolitan (local), city to city (within the
United  States) and  international  (from the United States to another  country)
private line, non-switchable circuits (the "Private Line Services").

1. Any state or federal  tariffs  applicable  to the Private Line Services to be
delivered  under any Customer  Order are  incorporated  into the terms  thereof.
Level 3's pricing to Customer for Private  Line  Services  may, if required,  be
subject to Public Utility Commission (PUC) or other regulatory approval.

2. The  nonrecurring  charges and monthly  recurring  rates for the Private Line
Services provided by Level 3 shall be set forth in each Customer Order.

3. The rates and other charges set forth in each Customer Order are  established
in reliance on the term commitment made therein, and Customer shall pay the same
in accordance therewith.  In the event that Customer terminates Services ordered
in any  Customer  Order  which is  accepted  by Level 3 or in the event that the
delivery of Services is  terminated  due to a failure of Customer to satisfy the
requirements  set forth in these  Terms and  Conditions  prior to the end of the
agreed term,  Customer shall (unless Customer has made a Revenue Commitment) pay
a termination  charge equal to the percentage of the monthly  recurring  charges
for the terminated Private Line Services calculated as follows:

a.    100% of the monthly  recurring  charge that would have been  incurred  for
the Private Line Service for months 1-12 of the agreed term; plus

b.    75% of the monthly  recurring charge that would have been incurred for the
Private Line Service for months 13-24 of the agreed term; plus

c.    50% of the monthly recurring charge that would have been incurred  for the
Private Line Service for months 25 through the end of the agreed term.

In the event that a Revenue  Commitment  is made and is then being  satisfied by
Customer,  Customer may  terminate,  rearrange or  reconfigure  the Private Line
Services  ordered  under a Customer  Order  without  payment of the  termination
charge specified above;  PROVIDED,  HOWEVER,  that Customer shall be responsible
for payment of Level 3's then-current  standard  nonrecurring charges applicable
to such termination, rearrangement or reconfiguration.

4. Level 3 makes the Service  Level  Agreements as attached  respecting  Private
Line Service.

Level 3 Private Line Services  (PLS) are backed by the  following  Service Level
Agreement  (SLA).  If the Level(3)  obligation  is missed,  the credit set forth
below will be issued to the Customer if requested, once verified by Level 3. The
total  number of credits  per month is limited to the Monthly  Recurring  Charge
(MRC) for the affected Service.  To receive credit if these obligations have not
been met, the Customer  must contact  Level 3 Customer  Service  within five (5)
days of the end of the month for which credit is requested.

Service for all issues -including  technical,  billing,  and product  inquiries:
1-877-4LEVEL3 (1-877-453-8353).

An order is accepted by Level 3 (for the purposes of this Installation Guarantee
only) as soon as the Order  Entry  Specialist  receives  the  order in  Customer
Implementation Management (CIM).

Individual Case Basis (ICB) Definition
Individual  Case Basis  (ICB) is defined as a Service  where a standard  service
interval is not defined.  For ICB categories,  Level 3 will provide a Firm Order
Commitment  Date  (FOC)  for  Services  as soon  as  possible.  The FOC  date is
determined by a combination  of Level 3 internal  processes as well as the dates
supplied to Level 3 by Level 3 vendors (where applicable). These vendor-supplied
FOC dates vary by vendor, region, and city.

Changes to Existing Orders in Progress
The SLA implementation  dates apply to intervals between original order date and
original due date. If the Customer requests a change to an order date during the
implementation of a service, the following effects will occur:

 99.99% Service Availability Guarantee*
 Service Unavailability refers to a period during which there is a break in transmission,  reported to and confirmed
 by Level 3 Customer  Service.  The start of the break is signaled by the first of ten  consecutive  severely  erred
 seconds ("SESs"),  as defined below, and the end is signaled by the first of ten consecutive  non-SESs. An SES is a
 second with a bit error ratio of greater than or equal to 1 in 1000. Service  Unavailability  does not include SESs
 associated with maintenance events,  Customer-caused  SESs or SESs caused by companies other than Level 3. Customer
 will  receive  credits,  calculated  monthly  as an  aggregate  of all  Service
 Unavailability events, in accordance with the chart below:

 Service unavailable 15 minutes                                                                  no credit

 +The total  number of credits  per month is  limited to the  Monthly  Recurring
  Charge (MRC) for the affected service.

 Service  Availability  is calculated from the ingress of the Level 3 Network to
 the egress of the Level 3 network.  Where a Customer is served  directly by the
 Level 3 Metro networks (lit by Level 3 fiber) this parameter is extended to the
 Customer   building.   Where  we  are   dependant   upon  a  third   party  for
 localonnectivity to the backbone, the availability of 99.99% is applicable from
 Level 3 Gateway to Level 3 Gateway.  For circuits  terminating in Germany,  the
 local  loop will  hold,  and the  availability  target of 97.5% is  applicable.
 Please see note on Germany  below.  Local Loop shall mean the  facilities  from
 Customer's Premises to the Level 3 Gateway.

 *NOTE:  If the  Customer has signed a contract  governed by German law,  and/or
 Private Line service is  provisioned  in Germany,  the  following  Availability
 Guarantee shall instead apply:

 Local Loop Guarantee: 97.5% Annual Availability
 Service  Unavailability is calculated as the total number of outages a Customer
 experiences  during a calendar month. The maximum Service  Unavailability  time
 may vary  depending  on the total  number of days in the month.  Example:  in a
 365-day year, the Service Unavailability maximum would be 219 hours. If Level 3
 exceeds the maximum Service  Unavailability time of 219 hours over the first 12
 months  of the  Customer's  contract,  then  Level 3 would be liable to pay the
 Customer  service  credits for the Service  Unavailability  time  exceeding 219
 hours.

                         ADDITIONAL TERMS AND CONDITIONS
                                 FOR COLOCATION

The following additional terms and conditions are applicable where,  pursuant to
a Customer Order, Customer orders the use of space within Level 3 Gateways to be
used for the purpose of  colocating  telecommunications  equipment  or equipment
used for connection to the internet (the "Space").

1.  Customer is granted the right to occupy the Space  identified  in a Customer
Order. Customer shall be permitted reasonable access to the Space subject to any
and all rules,  regulations and access requirements imposed by Level 3 governing
such access.  Customer may submit  multiple  Customer  Orders  requesting use of
different Space, each of which shall be governed by the terms hereof.

2.  Customer  shall  be  permitted  to use the  Space  only  for  placement  and
maintenance of communications  equipment. The nonrecurring and monthly recurring
charges for the Space and any Services ordered by Customer shall be set forth in
each Customer Order.  Customer hereby agrees,  within six (6) months of ordering
such Space, to use the Space for placement and maintenance of telecommunications
or internet access equipment.  In the event Customer fails to fill said Space as
set forth herein,  Level 3 has the right to reclaim the  proportion of Space not
being used  exclusively  as  indicated  above,  if the same is not cured  within
forty-five  (45) days' prior  notice  thereof to  Customer.  Customer  agrees to
immediately vacate such recaptured Space and Level 3 shall reduce the Colocation
fees allocated to such recaptured Space. Customer further agrees that no refunds
shall be made to Customer regarding such recaptured Space.

3.  Level  3 shall  perform  such  janitorial  services,  environmental  systems
maintenance,  power  plant  maintenance  and  other  actions  as are  reasonably
required  to  maintain  the gateway in which the Space is located in a condition
which is suitable for the placement of  telecommunications  and internet  access
equipment.  Customer shall maintain the Space in an orderly and safe  condition,
and shall return the Space to Level 3 at the conclusion of the term set forth in
the Customer Order in the same condition  (reasonable wear and tear excepted) as
when such Space was delivered to Customer.  EXCEPT AS EXPRESSLY STATED HEREIN OR
IN ANY  CUSTOMER  ORDER,  THE SPACE SHALL BE  DELIVERED  AND ACCEPTED "AS IS" BY
CUSTOMER,  AND NO  REPRESENTATION  HAS BEEN MADE BY LEVEL 3 AS TO THE FITNESS OF
THE SPACE FOR CUSTOMER'S INTENDED PURPOSE.

4.  The term of use of the Space  shall  begin on the later to occur of the date
requested  by Customer or the date that Level 3 completes  the  build-out of the
Space. Build out shall mean Level 3's construction and installation of the Space
for use by Customer.  Customer's  use of the Space beyond the initial term shall
be on a month-to-month basis, unless Customer and Level 3 have agreed in writing
to a renewal of the right to use such Space.  Customer  hereby agrees to pay for
the Space and any related Services for the term of this Agreement. The rates and
other charges set forth in each Customer  Order are  established  in reliance on
the term  commitment  made  therein.  In the event that  Customer  terminates  a
Customer  Order for Space  which is accepted by Level 3 or in the event that the
Customer  Order is  terminated  due to a failure  of  Customer  to  satisfy  the
requirements  set forth herein or in the Customer  Order prior to the end of the
agreed term, Customer shall pay a termination charge equal to the costs incurred
by Level 3 in  returning  the  Space to a  condition  suitable  for use by other
parties,  plus the  percentage of the monthly  recurring fees for the terminated
Space calculated as follows:

a.       100% of the  monthly  recurring  fees that would have been  charged for
the Space for months 1-12 of the agreed term; plus

b.       75% of the monthly  recurring fees that would have been charged for the
Space for months 13-24 of the agreed term; plus

c.       50% of the  monthly  recurring  fees that would have been  charged  for
the Space for months 25 through the end of the agreed term.

In the event that a Revenue  Commitment  is made and is then being  satisfied by
Customer,  Customer may terminate the Space ordered pursuant to a Customer Order
without payment of the termination  charge specified above;  PROVIDED,  HOWEVER,
that  Customer  shall be  responsible  for  payment  of Level  3's  then-current
standard nonrecurring charges applicable to such termination.

5.  Level 3 shall use reasonable  efforts to complete the build-out and make the
Space available to Customer on or before the date requested by Customer.  In the
event that Level 3 fails to complete the build-out within sixty (60) days of the
date  requested by Customer,  then Customer may terminate its rights to use such
Space and  receive a refund  of any fees paid for the use or  build-out  of such
Space.

6.  Customer shall abide by any posted or otherwise communicated  rules relating
to use of, access to, or security measures respecting the Space.  Customer's use

                                 Page 12 of 27
<PAGE>

of the Space will be immediately  terminated in the event Customer or any of its
agents or  employees  is found in Level 3's Gateway  with any  firearms,  drugs,
alcohol or is found engaging in any criminal  activity,  eavesdropping,  foreign
intelligence,  card  selling or  slamming.  Persons  found  engaging in any such
activity  or in  possession  of the  aforementioned  prohibited  items  will  be
immediately  escorted from the Gateway.  In the event that unauthorized  parties
gain access to the Space  through  access  cards,  keys or other access  devices
provided to Customer,  Customer shall be responsible for any damages incurred as
a result  thereof.  Customer shall be responsible  for the cost of replacing any
security devices lost or stolen after delivery thereof to Customer. In addition,
Level 3 shall  have the right to  terminate  Customer's  use of the Space or the
Services  in the event  that:  (a) Level 3's rights to use the  facility  within
which the Space is located  terminates  or expires for any reason;  (b) Customer
has violated the terms hereof or of any Customer Order submitted hereunder;  (c)
Customer makes any material alterations to the Space without first obtaining the
written  consent of Level 3; (d) Customer  allows  personnel or  contractors  to
enter  the  Space  who have  not been  approved  by Level 3 in  advance;  or (e)
Customer violates any posted or otherwise  communicated rules relating to use of
or access to the Space.  With respect to items (b), (c), (d) and (e) immediately
above,  unless the same  interferes or has the potential to interfere with other
Level 3 Colocation customers, Level 3 shall provide Customer a written notice of
the  foregoing  and a 10-day  opportunity  to cure the same  before  terminating
Customer's rights to the Space.

7.  Customer  may  sublease  the Space under the  following  conditions:  i) all
proposed  sublessees must be approved,  in writing, by Level 3 in Level 3's sole
discretion;  ii) Customer hereby  guarantees that all Sublessees  shall abide by
all terms and conditions  set forth between  Customer and Level 3; iii) Customer
shall  indemnify,  defend  and hold Level 3  harmless  from all  claims  brought
against  Level 3 arising from any act or omission of any  subcontractor  and iv)
any sublessee shall be considered  Customer's  agent and all of sublessees' acts
and omissions and usage of the Space or Services hereunder shall be attributable
to Customer for the purposes of these Terms and Conditions.

8.  Level 3 reserves the right to change the  location or  configuration  of the
Space, provided, however, that Level 3 shall not arbitrarily or discriminatorily
require such changes.  Level 3 and Customer shall work in good faith to minimize
any  disruption  in  Customer's  services  that may be caused by such changes in
location or configuration of the Space.

9.  Prior to occupancy and during the term of use of any Space,  Customer  shall
procure and maintain the  following  minimum  insurance  coverage:  (a) Workers'
Compensation  in  compliance   with  all  applicable   statutes  of  appropriate
jurisdiction.  Employer's  Liability with limits of $500,000 each accident;  (b)
Commercial  General  Liability  with combined  single limits of $1,000,000  each
occurrence;  and (c) "All Risk"  Property  insurance  covering  all of Customers
personal property located in the Space.  Customer's Commercial General Liability
policy shall be endorsed to show Level 3 (and any underlying  property owner, as
requested by Level 3) as an additional insured.  All policies shall provide that
Customer's  insurers waive all rights of  subrogation  against Level 3. Customer
shall furnish Level 3 with certificates of insurance demonstrating that Customer
has obtained the required  insurance  coverages prior to occupancy of the Space.
Such  certificates  shall contain a statement that the insurance  coverage shall
not be materially  changed or cancelled  without at least thirty (30) days prior
written notice to Level 3. Customer  shall require any  contractor  entering the
Space on its behalf to procure and maintain the same types, amounts and coverage
extensions as required of Customer above.

10. Customer may order and pay for Level 3 to perform  certain limited  ("Remote
Hands")  maintenance  services on Customer's  equipment within the Space,  which
shall be performed in accordance  with  Customer's  directions.  "Remote  Hands"
maintenance services includes power cycling equipment. Level 3 shall in no event
be  responsible  for the repair,  configuration  or tuning of equipment,  or for
installation of Customer's  equipment  (although Level 3 will provide reasonable
assistance to Customer in such installation).

11. Level 3 makes the Service Level Agreement as attached respecting  Colocation
Services.

Service  Unavailability  refers to any outage reported by the Customer within 48
hours  of the  outage  and  confirmed  by  Level  3  Customer  Service.  Service
Unavailability  covers any outage  associated with the Customer's access port to
the Level 3 Internet network, extending across the Level 3 Internet network, and
across the local  access  circuit  if  provisioned  on the Level 3  metropolitan
network.  Service  Unavailability  does  not  include  outages  associated  with
scheduled  maintenance  events,  Customer-caused  outages  or  disruptions,  the
performance  of Internet  networks  controlled  by other  companies,  or traffic
exchange points which are controlled by other companies.

We guarantee that for any outage lasting  between 15 minutes and 24 hours within
the same 24-hour period, Customers will receive a 1-day credit.

*NOTE: If the Customer has signed a contract  governed by German law, and/or DIA
service is provisioned in Germany, the following  Availability  Guarantees shall
instead apply:

Local Loop Guarantee: 97.5% Annual Availability
Service  Unavailability  is calculated  as the total number of outages  Customer
experiences during a calendar month. The maximum Service Unavailability time may
vary depending on the total number of days in the month.  Example:  in a 365-day
year, the Service  Unavailability maximum would be 219 hours. If Level 3 exceeds
the maximum Service Unavailability time of 219 hours over the first 12 months of
the  Customer's  contract,  then  Level 3 would be  liable  to pay the  Customer
service credits for the Service Unavailability time exceeding 219 hours.

Internet Network Guarantee: 99.9% Monthly Availability
Service  Unavailability  is calculated as the total number of outages a Customer
experiences during a calendar month. The maximum Service Unavailability may vary
depending on the total number of days in the month. Example: in a typical 30-day
month,  the  Service  Unavailability  maximum  would be 44  minutes.  If Level 3
exceeds  the maximum  Service  Unavailability  time of 44 minutes,  then Level 3
would be liable to pay the  Customer  a  service  credit  equal to time of total
Service Unavailability exceeding 44 minutes.

                       ADDITIONAL TERMS AND CONDITIONS FOR
           MANAGED MODEM -- DEDICATED, QUICKSTART AND TRANSIT SERVICES

The following additional terms and conditions are applicable where,  pursuant to
a Customer Order Customer orders services required to allow access to "Dedicated
Services," "Dedicated Service with QuickStart" and "Transit Services" as offered
by Level 3 (the "Managed Modem Services") ordered by Customer under any Customer
Order.

1.  Any state or federal tariffs  applicable to the Managed Modem Services to be
delivered under any Customer Order are incorporated into the terms thereof.

2.  In the event Customer orders  "Dedicated  Service," end user traffic will be
routed  through and  aggregated  in Level 3's facility,  sent to the  Customer's
Premises via a dedicated  circuit,  and then routed to its final  destination by
Customer. In the event that Customer orders "Transit Services," End User traffic
will be routed to Level 3's facility and then routed to its final destination by
Level 3 via the Internet.  Dedicated Service with "QuickStart" will initially be
provisioned to the Customer in the same fashion as Transit Services,  until such
time as Level 3 has provisioned  the dedicated  circuit to send end user traffic
from Level 3's  facility to the  Customer's  Premises.  QuickStart  will then be
migrated to standard  Dedicated  Service.  Customers ordering Dedicated Services
will be required to make a portion of the Premises  available to Level 3 for the
placement  of  equipment  necessary  to provide  such  Dedicated  Services.  For
Dedicated Service,  all Customer Provided Equipment (CPE) as well as the private
line necessary to support this service will be ordered, installed and managed by
Level 3.  Level 3 cannot and does not  guarantee  the  availability  of any port
ordered for  installation  greater than 90 days from the date of the order.  Any
telephone numbers used in providing the Managed Modem Services shall be released
to  Customer  upon  expiration  or  termination  hereof to the extent that it is
technically  feasible for Level 3 to port packet switched  telephone numbers and
then only if Customer is in compliance  with all of the terms  contained  herein
and in the General Terms and Conditions.

3.  Section  1.1 of the General  Terms and  Conditions  for  Delivery of Service
notwithstanding, a Customer Order for Managed Modem Service shall be accepted by
Level 3 once Level 3 has provisioned and tested such ports.  Customer's  billing
respecting  said ports shall  commence  once tested and found to be  functioning
properly by Level 3 notwithstanding  Customer's:  i) refusal to accept the ports
or ii) Customer's  refusal to acknowledge  communications by Level 3 to Customer
respecting the ports. In the event Customer moves an installation  date provided
by Level 3 more  than ten (10)  business  days out from the  original  requested
date,  Level 3 will begin billing for Managed Modem Service eleven (11) business
days after the initial requested installation date whether or not the Service is
installed.

4.  The nonrecurring  charges and monthly  recurring rates for the Managed Modem
Services  provided  by Level 3 to Customer  shall be set forth in each  Customer
Order.  Level 3 will  dedicate  the  specified  number of ports to  Customer  as
identified in each Customer Order.

Customer  shall have the option to purchase  twenty  percent  (20%) port overage
from  Level 3 as  described  below.  If  ordered,  Level 3  shall  provision  an
additional  twenty  percent  (20%) of ports  over the  number of ports  actually
ordered by Customer to accept Customer traffic in the event  Customer's  traffic
bursts and its usage exceeds the capacity of the ports actually ordered.  In the
event  Customer  chooses not to purchase  twenty percent (20%) port overage from
Level 3, if the Customer's traffic bursts as set forth above,  Customer will get
a busy signal in the event its ordered  capacity is exceeded.  In the event that
Customer purchases 20% port overage, Customer will be responsible for additional
monthly  charges to the extent it utilizes any additional  capacity  provided by
Level 3.

5.  Customer must utilize all Managed  Modem ports  provisioned  hereunder at no
less than fifty percent (50%) of the capacity of such port.  Customer  agrees to
allow Level 3 to monitor Customer's utilization of the ports provisioned herein.
In the event Customer is Under-Utilizing  (as defined below) such ports, Level 3
retains  the right to reclaim  such ports  after  which  Customer  shall have no
further right to use the ports Under-Utilized. Termination liability shall apply
to any ports reclaimed pursuant to this paragraph.

For the purpose of this Section,  "Under-Utilization" shall mean the use of less
than fifty  percent  (50%) of the  capacity of any given port for any sixty (60)
day period as determined by Level 3.  Under-Utilization  shall not be applicable
to the first sixty (60) day period immediately following the provisioning of any
Managed Modem port.

6.  The rates and other charges set forth in each Customer Order are established
in reliance on the term commitment made therein,  and Customer agrees to pay the
same. In the event that Customer  terminates  Managed Modem Services  ordered in
any  Customer  Order  which  is  accepted  by Level 3 or in the  event  that the
delivery of Managed Modem Services is terminated due to a failure of Customer to

                                 Page 21 of 27
<PAGE>
satisfy the  requirements set forth herein or in the Customer Order prior to the
end of the agreed  term,  Customer  shall  (unless  Customer  has made a Revenue
Commitment)  pay a  termination  charge equal to the  percentage  of the monthly
recurring  charges for the  terminated  Managed  Modem  Services  calculated  as
follows:

a.       100% of the monthly  recurring charge that would have been incurred for
the Managed Modem Service for months 1-12 of the agreed term; plus

b.       75% of the monthly  recurring  charge that would have been incurred for
the Managed Modem Service for months 13-24 of the agreed term; plus

c.       50% of the monthly  recurring  charge that would have been incurred for
the Managed  Modem  Service  for months 25 through  the end of the agreed  term.
Customer  may, in the event that a Revenue  Commitment is made and is then being
satisfied by Customer,  terminate,  rearrange or  reconfigure  the Managed Modem
Services  ordered  under a Customer  Order  without  payment of the  termination
charge specified above;  PROVIDED,  HOWEVER,  that Customer shall be responsible
for payment of Level 3's  then-current  standard  nonrecurring  charges for such
termination, rearrangement or reconfiguration.

7.  Level 3 provides only  access to the  Internet;  Level 3 does not operate or
control the  information,  services,  opinions or other content of the Internet.
Customer agrees that it shall make no claim whatsoever  against Level 3 relating
to the content of the Internet or respecting any information,  product,  service
or software ordered through or provided by virtue of the Internet.

8.  Level 3 makes the Service  Level  Agreement  as attached  respecting Managed
Modem Services.

Service  Unavailability  refers to any outage reported by the Customer within 48
hours  of the  outage  and  confirmed  by  Level  3  Customer  Service.  Service
Unavailability  covers any outage  associated with the Customer's access port to
the Level 3 Internet network, extending across the Level 3 Internet network, and
across the local  access  circuit  if  provisioned  on the Level 3  metropolitan
network.  Service  Unavailability  does  not  include  outages  associated  with
scheduled  maintenance  events,  Customer-caused  outages  or  disruptions,  the
performance  of Internet  networks  controlled  by other  companies,  or traffic
exchange points which are controlled by other companies.

We guarantee that for any outage lasting  between 15 minutes and 24 hours within
the same 24-hour period, Customers will receive a 1-day credit.

*NOTE: If the Customer has signed a contract  governed by German law, and/or DIA
service is provisioned in Germany, the following  Availability  Guarantees shall
instead apply:

Local Loop Guarantee: 97.5% Annual Availability
Service  Unavailability  time is  calculated  as the total  number of  outages a
Customer experiences during a calendar month. The maximum Service Unavailability
may vary  depending  on the total  number of days in the  month.  Example:  in a
365-day year, the Service  Unavailability maximum would be 219 hours. If Level 3
exceeds the maximum Service  Unavailability  time of 219 hours over the first 12
months  of the  Customer's  contract,  then  Level 3 would be  liable to pay the
Customer service credits for the Service Unavailability exceeding 219 hours.

Internet Network Guarantee: 99.9% Monthly Availability
Service  Unavailability  time is  calculated  as the total  number of  outages a
Customer experiences during a calendar month. The maximum Service Unavailability
may vary  depending  on the total  number of days in the  month.  Example:  in a
typical 30-day month, the Service Unavailability maximum would be 44 minutes. If
Level 3 exceeds the maximum Service Unavailability time of 44 minutes, thenLevel
3 would be liable to pay the  Customer a service  credit  equal to time of total
Service Unavailability exceeding 44 minutes.

                                       AND
                                   THE COMPANY

This Commercial  Pilot  Agreement  ("Agreement")  is by and between  TransNexus,
L.L.C.  , a business  entity  organized as a  Corporation  under the laws of the
State of Georgia,  with a registered address at 430 Tenth Street NW, Suite N204,
Atlanta,  GA,  30318  USA,  and  VDC  Telecommunications,  Inc.  (The  Company),
incorporated  in Delaware and located at address 75 Holly Hill Lane,  Greenwich,
CT 06830.

The Solution.  TransNexus is the owner of a Clearinghouse Solution identified as
"ClearIPSM".  ClearIPSM  is a complete  turnkey  solution  for  inter-IP  domain
traffic authorization,  billing, clearing and settlement. The ClearIPSM solution
provides a web user  interface  which is used for  provisioning  wholesale  rate
plans  for IP  devices,  enrolling  IP  devices  in the  clearinghouse  network,
managing the credit status of IP devices in the clearinghouse network,  managing
the status of  clearinghouse  customer  service  representatives,  clearinghouse
customers  and  TransNexus  customer  service   representatives.   In  addition,
ClearIPSM  Service Points on the IP network provide real time  authorization and
routing of IP traffic  among the IP domains of  clearinghouse  customers.  These
same service  points also collect the  resulting  usage records of authorized IP
transactions and forward those records to the TransNexus operations center where
inter-IP domain usage records are reconciled,  rated and settled among IP domain
operators using the clearinghouse  service.  As an Application Service Provider,
TransNexus  operates  the  ClearIPSM  Clearinghouse  solution  on  behalf of our
customers.

Technical  specifications.  The  following  devices are  currently  certified by
TransNexus as being compliant with the Open  Settlement  Protocol and TransNexus
requirements.  We expect that  additional  Cisco and Lucent VoIP devices will be
certified by TransNexus by the end of Q12000.

                  2.       Payment  of  Exercise  Price.   The  option  may   be
exercised,  in part or in whole,  only by  written  request  to the  Corporation
accompanied by payment of the exercise price in full either: (i) in cash for the

directly to the Corporation to pay the exercise  price;  (iii) in the discretion
of  the  Plan  Administrator,   through  the  delivery  to  the  Corporation  of
previously-owned  shares of Common Stock  having an aggregate  Fair Market Value

in payment of the option  price must have been held by the Optionee for at least
six (6)  months in order to be  utilized  to pay the option  price;  (iv) in the
discretion  of the Plan  Administrator,  through an  election  to have shares of
Common Stock  otherwise  issuable to the  Optionee  withheld to pay the exercise
price  of such  Option;  or (v) in the  discretion  of the  Plan  Administrator,
through any combination of the payment procedures set forth in Subsections (i) -

                       UNDER THE VDC COMMUNICATIONS, INC.
               1998 STOCK INCENTIVE PLAN, AS AMENDED (the "Plan")

                  NOW,  THEREFORE,  the parties hereto,  intending to be legally
bound,  hereby agree that as of the Grant Date,  the  Corporation  hereby grants

Stock  granted  herein is subject to the terms,  conditions,  and  covenants set
forth in the Plan as well as the following:

<PAGE>

                           (a)      This option  shall  constitute  an Incentive
                                    Stock  Option  which is  intended to qualify
                                    under  Section 422 of the  Internal  Revenue
                                    Code of 1986, as amended;

                           (b)      The per share  exercise price for the shares

                                    higher  than 100% of the Fair  Market  Value
                                    (as defined in the Plan) of the Common Stock
                                    on the Grant Date,  which  exercise price is
                                    set forth on Schedule A hereto;

                           (c)      This option  shall vest in  accordance  with
                                    the vesting schedule set forth on Schedule A
                                    hereto; and

                           (d)      No portion of this  option may be  exercised
                                    more  than ten  (10)  years  from the  Grant
                                    Date.

                  2.       Payment  of  Exercise  Price.    The  option  may  be
exercised,  in part or in whole,  only by  written  request  to the  Corporation
accompanied by payment of the exercise price in full either: (i) in cash for the
shares  with  respect  to  which  it is  exercised;  (ii) by  delivering  to the
Corporation   a  notice  of  exercise  with  an   irrevocable   direction  to  a

to sell a  sufficient  portion  of the  shares  and  deliver  the sale  proceeds
directly to the Corporation to pay the exercise  price;  (iii) in the discretion
of  the  Plan  Administrator,   through  the  delivery  to  the  Corporation  of
previously-owned  shares of Common Stock  having an aggregate  Fair Market Value
equal to the option exercise price of the shares being purchased pursuant to the
exercise of the Option; provided, however, that shares of Common Stock delivered
in payment of the option  price must have been held by the Optionee for at least
six (6)  months in order to be  utilized  to pay the option  price;  (iv) in the
discretion  of the Plan  Administrator,  through an  election  to have shares of
Common Stock  otherwise  issuable to the  Optionee  withheld to pay the exercise
price  of such  Option;  or (v) in the  discretion  of the  Plan  Administrator,
through any combination of the payment procedures set forth in Subsections (i) -
(iv) of this paragraph.

                  3.       Miscellaneous.

entering into this Agreement.

         As further  consideration  for this  Agreement,  Lessor  represents and

         The parties  understand that the payment of the aforesaid sum by Lessee
and the exchange of other consideration hereunder is in settlement of a disputed
claim,  and that the said  payment and  exchange of  consideration  is not to be

in this Agreement.  This paragraph adds to and supplements the other  paragraphs

                          SECURITIES PURCHASE AGREEMENT

         THIS SECURITIES  PURCHASE AGREEMENT (the "Agreement" or the "Securities
Purchase  Agreement") is entered into as of the 26th day of April,  2000, by and
between  VDC  Communications,   Inc.,  a  Delaware  corporation  ("VDC"  or  the
"Company"),  and the investor  whose name  appears at the end of this  Agreement

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

         The  Company  wishes  to  obtain  additional  working  capital  and the
Purchaser  desires to provide  such working  capital to the Company  through the
purchase of certain shares of the Company's  common stock,  $.0001 par value per
share (the "Common Stock"), being privately offered by the Company.

         NOW,  THEREFORE,  in  consideration  of the  premises  hereof  and  the
agreements set forth herein below,  the parties hereto,  intending to be legally
bound, hereby agree as follows:

         1.       Sale and Purchase of Shares.
                  ----------------------------

                  Subject to the terms and conditions hereof, the Company agrees
to issue and sell, and the Purchaser agrees to purchase that number of shares of
Common  Stock  (the  "Shares")  identified  on the  signature  page  hereof at a

                  (a)      Restricted   Securities.    The  Shares   shall    be
"restricted securities" as that term is defined under Rule 144 of the Securities
Act of 1933, as amended (the "Act"),  and may not be offered for sale or sold or
otherwise  transferred  in a transaction  which would  constitute a sale thereof
within the meaning of the Act unless (i) such security has been  registered  for
sale under the Act and registered or qualified under applicable state securities
laws relating to the offer and sale of securities;  or (ii)  exemptions from the
registration  requirements  of the  Act and the  registration  or  qualification
requirements  of all such state  securities  laws are  available and the Company
shall  have  received  an opinion of  counsel  that the  proposed  sale or other
disposition of such securities may be effected  without  registration  under the
Act and would not result in any  violation of any  applicable  state  securities
laws relating to the  registration or qualification of securities for sale, such
counsel and such opinion to be satisfactory to the Company.

commitment   to   investments   which  are  not   readily   marketable   is  not
disproportionate to his net worth; (ii) investment in the Company will not cause

                                       3
<PAGE>

such overall  commitment to become excessive;  (iii) can afford to bear the loss
of his  entire  investment  in the  Company;  and  (iv)  has  adequate  means of
providing for his current needs and personal  contingencies  and has no need for
liquidity in his investment in the Company;

                  (c)      Special  Suitability.   The  Purchaser  satisfies any

and/or the state in which the  transaction  by which the  Shares  are  purchased
occurs;

                  (d)      Investment Intent. The Purchaser hereby  acknowledges
that the Purchaser  has been advised that this offering has not been  registered
with, or reviewed by, the Securities  and Exchange  Commission  ("SEC")  because
this offering is intended to be a non-public  offering  pursuant to Section 4(2)
and  Regulation  D of the Act. The  Purchaser  represents  that the  Purchaser's
Shares are being  purchased for the Purchaser's own account and not on behalf of
any other  person,  for  investment  purposes  only and not with a view  towards
distribution or resale to others.  The Purchaser  agrees that the Purchaser will
not attempt to sell, transfer, assign, pledge or otherwise dispose of all or any
portion of the Shares unless they are registered  under the Act or unless in the
opinion  of counsel an  exemption  from such  registration  is  available,  such
counsel  and such  opinion to be  satisfactory  to the  Company.  The  Purchaser
understands  that the Shares have not been registered under the Act by reason of
a claimed exemption under the provisions of the Act which depends, in part, upon
the Purchaser's investment intention;

                  (e)      State Securities Laws. The Purchaser understands that
no securities  administrator  of any state has made any finding or determination
relating to the fairness of this investment and that no securities administrator
of any state has  recommended  or endorsed,  or will  recommend or endorse,  the
offering of the Shares;

                  (f)      Authority; Power;  No   Conflict.    The   execution,
delivery and performance by the Purchaser of the Agreement are within the powers
of the Purchaser, have been duly authorized and will not constitute or result in
a breach or default under, or conflict with, any order,  ruling or regulation of
any court or other tribunal or of any governmental  commission or agency, or any
agreement or other  undertaking,  to which the  Purchaser is a party or by which
the  Purchaser is bound,  and, if the Purchaser is not an  individual,  will not
violate any  provision  of the charter  documents,  Bylaws,  indenture of trust,
operating agreement, or partnership agreement, as applicable,  of the Purchaser.
The signatures of the Purchaser on the Agreement are genuine, and the signatory,
if the Purchaser is an individual,  has legal competence and capacity to execute
the same, or, if the Purchaser is not an individual, the signatory has been duly
authorized to execute the same; and the Agreement  constitutes the legal,  valid
and binding  obligations  of the Purchaser,  enforceable in accordance  with its
terms;

                  (g)      No General Solicitation.  The Purchaser  acknowledges
that no general  solicitation or general advertising  (including  communications
published in any  newspaper,  magazine or other  broadcast) has been received by
him and  that no  public  solicitation  or  advertisement  with  respect  to the
offering of the Shares has been made to him;

relied solely upon the advice of his own tax and legal  advisors with respect to
the tax and other legal aspects of this investment;

                  (i)      Broker Fees.  The  Purchaser  is  not  aware that any
person,  and has been advised that no person,  will receive from the Company any
compensation as a broker, finder, adviser or in any other capacity in connection
with the purchase of the Shares;

                  (j)      Access to  Information.  Purchaser  has had access to
all material and relevant  information  concerning the Company,  its management,
financial  condition,   capitalization,   market  information,   properties  and
prospects  necessary to enable Purchaser to make an informed investment decision
with respect to its  investment in the Shares.  Purchaser has carefully read and
reviewed,  and is familiar with and understands the contents thereof and hereof,
including,  without  limitation,  the risk factors referenced in this Agreement.
See "Understanding of Investment Risks." Purchaser  acknowledges that it has had
the  opportunity  to ask questions of and receive  answers  from,  and to obtain
additional information from, representatives of the Company concerning the terms
and  conditions  of the  acquisition  of the Shares and the present and proposed
business and financial condition of the Company,  and has had all such questions
answered to its satisfaction and has been supplied all information requested;

                  (k)      Review of Reports. The Purchaser acknowledges that it

Commission  under  the  Securities  Exchange  Act  of  1934  (collectively,  the

                  (l)      Understanding the Nature of Securities. The Purchaser
understands and acknowledges that:

                           (i)      The Shares have not  been  registered  under
the Act or any state  securities  laws and are being issued and sold in reliance
upon certain exemptions contained in the Act;

                           (ii)     The Shares  are  "restricted  securities" as
that term is defined in Rule 144 promulgated under the Act;

                           (iii)    The Shares cannot  be  sold  or  transferred
without  registration  under the Act and applicable  state  securities  laws, or
unless the Company  receives an opinion of counsel  reasonably  acceptable to it
(as to both counsel and the opinion) that such  registration  is not  necessary;
and

                                       5

                           (iv)     The Shares and any  certificates  issued  in
replacement  therefor shall bear the following  legend, in addition to any other

          NOT BEEN REGISTERED  UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
          "ACT"),  OR ANY APPLICABLE STATE SECURITIES LAWS. THESE SECURITIES MAY
          NOT BE SOLD,  TRANSFERRED  OR OTHERWISE  DISPOSED OF IN THE ABSENCE OF
          REGISTRATION,  OR THE  AVAILABILITY  OF EXEMPTION  FROM  REGISTRATION,
          UNDER THE ACT and any applicable  state  securities  laws, BASED ON AN
          OPINION LETTER OF COUNSEL SATISFACTORY TO THE COMPANY."

                  (m)      Information Provided. The Purchaser has, on or before
the date of the Closing, been afforded the opportunity to review and is familiar
with the Reports and has based his decision to invest solely on the  information
contained therein,  and the information  contained within this Agreement and the
associated  exhibits and  schedules,  and has not been furnished with and is not
relying upon any other  literature,  prospectus or other  information  except as
included in the Reports or this Agreement.

         6.       Indemnification.  The  Purchaser  shall  indemnify  and   hold
                  ----------------
harmless the Company and the Company's  officers,  directors and employees  from

due to, or  arising  out of, a breach or  inaccuracy  of any  representation  or
warranty contained in Section 5.

         7.       Understanding  of Investment  Risks.  Any  investment  in  the
                  ------------------------------------
Shares  should  not be made by a  Purchaser  who  cannot  afford the loss of his
entire Purchase Price. The Purchaser acknowledges that the Shares offered hereby
have not been approved or disapproved by the Securities and Exchange Commission,
or any  state  securities  commissions,  nor has  the  Securities  and  Exchange
Commission  or any state  securities  commission  passed  upon the  adequacy  or
accuracy of this Securities  Purchase Agreement or any exhibit hereto.  Prior to
making an investment in the Shares,  the Purchaser has fully  considered,  among
other things,  the financial and other  information  set forth in the Reports as
well as the risk  factors  enumerated  in the  Company's  Amendment  Number 1 to

         8.       Registration Rights.  The Company shall  advise the  Purchaser
                  --------------------

Securities Act (excluding registration on Forms S-8, S-4, or any successor forms
thereto),  covering securities of the Company to be offered and sold (whether by
the  Company or any  stockholder  thereof)  and shall,  upon the  request of the
Purchaser  given at least  five (5)  business  days  prior to the filing of such
registration  statement,   include  in  any  such  registration  statement  such
information  as may be  required  to  permit  an  offering  of the  Shares.  The
Purchaser shall promptly furnish such information as may be reasonably requested
by the Company in order to include  such Shares in the  registration  statement.

resale  thereof.  In all events,  the Company shall have no  obligation:  (i) to
assist or  cooperate  in the offering or  disposition  of such  Shares;  (ii) to

         9.  Representations  and Warranties of the Company.  The Company hereby
             -----------------------------------------------
represents and warrants to Purchaser as follows:

                  (a)      Organization and Standing of the Company. The Company
is a duly organized and validly existing  corporation in good standing under the
laws of the State of Delaware with  adequate  power and authority to conduct the
business in which it is now engaged and has the corporate power and authority to
enter into this Agreement,  and is duly qualified and licensed to do business as
a foreign  corporation in such other  jurisdictions as is necessary to enable it
to  carry on its  business,  except  where  failure  to do so  would  not have a
material adverse effect on its business;

                  (b)      Corporate  Power  and  Authority.  The  execution and
delivery of this Agreement and the  transactions  contemplated  hereby have been
duly authorized by the Board of Directors of the Company. No other corporate act
or  proceeding  on the  part of the  Company  is  necessary  to  authorize  this
Agreement.  When  duly  executed  and  delivered  by the  parties  hereto,  this
Agreement will constitute a valid and legally binding  obligation of the Company
enforceable   against  it  in  accordance   with  its  terms,   except  as  such
enforceability  may  be  limited  by  (i)  bankruptcy,  insolvency,  moratorium,
reorganization or other similar laws and legal and equitable principles limiting
or affecting the rights of creditors  generally;  and/or (ii) general principles
of equity, regardless of whether considered in a proceeding in equity or at law.


         10.      IMPORTANT CONSIDERATIONS:  SUITABILITY STANDARDS - WHO  SHOULD
                  --------------------------------------------------------------
INVEST.

                  INVESTMENT IN THE SHARES INVOLVES A HIGH DEGREE OF RISK AND IS
SUITABLE ONLY FOR PERSONS OF  SUBSTANTIAL  FINANCIAL  RESOURCES WHO HAVE NO NEED
FOR LIQUIDITY IN THEIR INVESTMENT.

                  A  substantial  number of state  securities  commissions  have
established  investor  suitability  standards  for the  marketing  within  their
respective  jurisdictions of restricted  securities.  Some have also established
minimum  dollar  levels for  purchases  in their  states.  The reasons for these
standards  appear  to be,  among  others,  the  relative  lack of  liquidity  of
securities  of such  programs as  compared  with other  securities  investments.
Investment in the Shares involves a high degree of risk and is suitable only for
persons of substantial  financial  means who have no need for liquidity in their
investments.

                  The  Company  has  adopted as a general  investor  suitability
standard the requirement  that each Subscriber for Shares  represents in writing
that the  Subscriber:  (a) is acquiring the Shares for investment and not with a
view to resale or  distribution;  (b) can bear the  economic  risk of losing his
entire  investment;  (c) his overall  commitment  to  investments  which are not
readily marketable is not  disproportionate  to his net worth, and an investment
in the Shares will not cause such overall  commitment to become  excessive;  (d)
has adequate means of providing for his current needs and personal contingencies
and  has no need  for  liquidity  in  this  investment  in the  Shares;  (e) has
evaluated all the risks of investment in the Company; and (f) has such knowledge
and experience in financial and business  matters as to be capable of evaluating
the  merits  and risks of  investing  in the  Company  or is  relying on his own
purchaser representative in making an investment decision.

                  In addition,  all of the  Subscribers  for Shares must be: (1)
extremely  sophisticated  investors with substantial net worth and experience in
making investments of this nature; and (2) "accredited investors," as defined in
Rule  501 of  Regulation  D under  the  Act,  by  meeting  any of the  following
conditions:

                  (i)      he  or  she  has  an  individual  income in excess of
$200,000  in each of the two most recent  years or joint  income with his or her
spouse in excess of $300,000 in each of those  years,  and he or she  reasonably
expects an income in excess of the aforesaid levels in the current year, or

                  (ii)     he or she has an  individual  net  worth,  or a joint
net worth with his or her spouse, at the time of his or her purchase,  in excess
of $1,000,000 (net worth for these purposes includes homes, home furnishings and
automobiles), or

                  (iii)    he  or she otherwise satisfies the Company that he or
she is an accredited investor, as defined in Rule 501 under the Act.

                  Other  categories of investors  included within the definition
of accredited investor include the following:  certain institutional  investors,
including  certain  banks,  whether  acting  in their  individual  or  fiduciary
capacities;   certain  insurance  companies;   federally  registered  investment
companies;  business  development  companies  (as defined  under the  Investment

                                       8
<PAGE>

Company Act of 1940); Small Business Investment  Companies licensed by the Small
Business  Administration;  certain  employee  benefit  plans;  private  business
development  companies (as defined in the Investment  Advisers Act of 1940); tax
exempt  organizations  (as defined in Section  501(c)(3) of the Internal Revenue
Code)  with  total  assets in excess of  $5,000,000;  entities  in which all the
equity owners are accredited investors; and certain affiliates of the Company.

                  A partnership Subscriber, which satisfies the requirements set
forth in clauses (a) through (f) above shall satisfy the  suitability  standards
if it is an  accredited  investor by reason of clause (iii) above,  or if all of
its partners are accredited investors.  A corporate subscriber,  which satisfies
the  requirements  set forth in clauses (a) through (f) above shall  satisfy the
investor  suitability  standards  if it is an  accredited  investor by reason of
clause (iii) above,  or if all of its  shareholders  are  accredited  investors.
Corporate subscribers must have net worth of at least three (3) times the amount
of their investment in the Shares.

                  The suitability  standards referred to above represent minimum
suitability requirements for prospective purchasers and the satisfaction of such
standards by a prospective  purchaser does not necessarily  mean that the Shares
are a suitable investment for such purchaser.  The Company may, in circumstances
it deems  appropriate,  modify  such  requirements.  The Company may also reject
subscriptions   for  whatever  reasons,   in  its  sole  discretion,   it  deems
appropriate.

                  Securities Purchase Agreements may not necessarily be accepted
in the order in which  received.  Purchasers who are residents of certain states
may be required to meet certain additional suitability standards.

                  THE  ACCEPTANCE  OF A  SUBSCRIPTION  FOR SHARES BY THE COMPANY
DOES NOT  CONSTITUTE A  DETERMINATION  BY THE COMPANY THAT AN  INVESTMENT IN THE
SHARES IS SUITABLE FOR A PROSPECTIVE  INVESTOR.  THE FINAL  DETERMINATION OF THE
SUITABILITY OF INVESTMENT IN THE SHARES MUST BE MADE BY THE PROSPECTIVE INVESTOR
AND HIS OR HER ADVISERS.


         11.      State Law Considerations.
                  -------------------------

                  (a)      For Residents of All States.

OWN  EXAMINATION  OF THE  ISSUER'S  SECURITIES  AND THE  TERMS OF THE  OFFERING,
INCLUDING  THE  MERITS  AND  RISKS  INVOLVED.  THESE  SECURITIES  HAVE  NOT BEEN
RECOMMENDED  BY  ANY  FEDERAL  OR  STATE  SECURITIES  COMMISSION  OR  REGULATORY
AUTHORITY.  FURTHERMORE,  THE  FOREGOING  AUTHORITIES  HAVE  NOT  CONFIRMED  THE
ACCURACY OR DETERMINED THE ADEQUACY OF THIS DOCUMENT.  ANY REPRESENTATION TO THE
CONTRARY IS A CRIMINAL OFFENSE.

                                       9
<PAGE>

         THESE  SECURITIES ARE SUBJECT TO  RESTRICTIONS ON  TRANSFERABILITY  AND
RESALE  AND MAY NOT BE  TRANSFERRED  OR  RESOLD  EXCEPT AS  PERMITTED  UNDER THE
SECURITIES  ACT,  AND  THE  APPLICABLE  STATES  SECURITIES  LAWS,   PURSUANT  TO
REGISTRATION OR EXEMPTION THEREFROM. INVESTORS SHOULD BE AWARE THAT THEY WILL BE
REQUIRED TO BEAR THE FINANCIAL RISKS OF THIS INVESTMENT FOR AN INDEFINITE PERIOD
OF TIME.

         THE INVESTOR MUST RELY ON THE INVESTOR'S OWN  EXAMINATION OF THE PERSON
OR ENTITY  CREATING THE SECURITIES AND THE TERMS OF THE OFFERING,  INCLUDING THE
MERITS AND RISKS INVOLVED, IN MAKING AN INVESTMENT DECISION ON THESE SECURITIES.

              (e)  Any case or  proceeding  is  voluntarily  commenced  by Maker

         10.  Governing Law. Maker, and each endorser and cosigner of this Note,
              --------------
              acknowledges  and agrees that this Note is made and is intended to
              be  paid  and  performed  in the  State  of  New  Jersey  and  the
              provisions hereof will be construed in accordance with the laws of
              the State of New Jersey and,  to the extent  that  federal law may
              preempt the  applicability of state laws,  federal law. Maker, and
              each  endorser and  cosigner of this Note further  agree that upon
              the  occurrence of an Event of Default,  this Note may be enforced
              in any court of competent jurisdiction in the State of New Jersey,
              and they do  hereby  submit  to the  jurisdiction  of such  courts
              regardless of their residence.

         11.  Remedies  Cumulative:  Waiver.  The remedies of Holder as provided
              ------------------------------
              herein shall be  cumulative  and  concurrent,  and  may be pursued
              singularly,  successively or  together,  in the sole discretion of
              Holder,  and may be exercised  as often as occasion therefor shall
              arise.  No act of omission   or  commission  of Holder,  including
              specifically  any  failure   to  exercise  any  right,  remedy  or
              recourse,  shall be deemed to  be a waiver or release of the same;
              such  waiver or release  to  be  affected  only  through a written
              document   executed  by  Holder  and   then  only  to  the  extent
              specifically recited therein.  Without  limiting the generality of
              the preceding sentence,  acceptance by  Holder of any payment with
              knowledge of the occurrence of an Event  of Default by Maker shall
              not be deemed a waiver of such Event of  Default,  and  acceptance
              by Holder of any  payment in an amount  less  than the amount then
              due  hereunder  shall be an  acceptance on  account only and shall
              not in any way  affect  the  existence  of  an  Event  of  Default
              hereunder.  A waiver or release  with  reference to any  one event
              shall not be construed as continuing, as a bar to, or as a  waiver
              or release of, any subsequent  right,  remedy or recourse as  to a
              subsequent event.

         12.  No Usury  Intended.  All agreements  between  Maker and Holder are
              -------------------
              expressly  limited  so that in no contingency or event whatsoever,
              whether  by reason of: error of fact or law;  payment,  prepayment
              or  advancement of the proceeds  hereof;  acceleration of maturity
              of  the Outstanding  Principal  Balance,  or otherwise,  shall the
              amount  paid or  agreed to be paid to Holder  hereof  for the use,
              forbearance  or  retention of the money to be advanced  hereunder,
              including any  charges  collected or made in  connection  with the
              indebtedness   evidenced  by this  Note  which may be  treated  as
              interest  under  applicable  law, if any, exceed the maximum legal
              limit  (if  any such  limit is  applicable)  under  United  States
              federal  law or state law (to the extent not  preempted by federal
              law, if  any), now or hereafter  governing the interest payable in
              connection   with  such  agreements.  If,  from any  circumstances
              whatsoever,  fulfillment  of  any  provision  hereof  at the  time
              performance  of   such  provision   shall  be  due  shall  involve
              transcending  the  limit of validity  (if any)  prescribed  by law
              which a court   of  competent  jurisdiction  may  deem  applicable
              hereto,  then  ipso facto, the obligation to be fulfilled shall be
              reduced  to   the  limit  of  such  validity,   and  if  from  any

                                       3

              circumstances,   Holder  shall ever  receive as interest an amount
              which would exceed  the maximum  legal limit (if any such limit is
              applicable),  such  amount which would be excessive interest shall
              be applied to the  reduction of the Outstanding  Principal Balance
              due  hereunder  and   not  to  the  payment  of  interest  or,  if
              necessary,  rebated  to Maker.  This provision shall control every
              other  provision of all agreements between Maker and Holder.

                   protect,  perfect,  retain or enforce  any  security  for the

                   as  a  defense  to  the   payment   hereof  any   statute  of
                   limitations.

              (b)  This  Note   and  each  payment  of  principal  and  interest
                   hereunder shall be paid when due without deduction or  setoff

                   including, but not limited to,  attorneys' fees (including an

                                       4
<PAGE>

                   allocable portion  of  in-house  counsel  fees)  incurred  in
                   connection with any bankruptcy  proceedings  instituted by or
                   against Maker (including relief from stay litigation).

              (d)  If any provision  hereof is for any reason and to any extent,
                   invalid or unenforceable,  then neither the  remainder of the
                   document in  which  such  provision  is  contained,  nor  the
                   application of the  provision to other  persons,  entities or
                   circumstances shall be affected thereby, but instead shall be
                   enforceable to the maximum extent permitted by law.

              (e)  This Note shall be a joint and several  obligation  of Maker,

                   representatives, successors and assigns.

              (f)  This Note may not be modified or amended orally, but only  by
                   a modification  or amendment in writing signed by Holder  and
                   Maker.

              (g)  When the context and construction so require,  all words used
                   in the  singular  herein shall be deemed to have been used in
                   the plural and the masculine  shall  include the feminine and
                   neuter and vice versa. The word "person" as used herein shall
                   include  any   individual,    company,   firm,   association,
                   partnership, corporation,  trust or other legal entity of any
                   kind whatsoever.

              (h)  The headings of the  paragraphs and sections of this Note are
                   for convenience or reference only, are not to be considered a
                   part hereof and shall not limit or otherwise  affect  any  of
                   the terms hereof.

              (i)  In the event that at any time any  payment received by Holder
                   hereunder shall  be  deemed  by  final  order  of a court  of
                   competent jurisdiction to have been a voidable  preference or
                   fraudulent conveyance under the bankruptcy or insolvency laws
                   of the United States,  or shall otherwise be deemed to be due
                   to any party other than Holder, then, in any such event,  the
                   obligation  to   make   such   payment   shall   survive  any
                   cancellation of this Note and/or return thereof  to Maker and
                   shall not be  discharged  or satisfied by any  prior  payment
                   thereof and/or cancellation of this Note, but shall  remain a
                   valid and binding obligation  enforceable in accordance  with
                   the  terms and  provisions  hereof,  and the  amount of  such
                   payment  shall bear  interest at the  Default  Rate from  the
                   date of such final order until repaid hereunder.

                               GUARANTY AGREEMENT
                               ------------------

     THIS  GUARANTY  AGREEMENT  ("Guaranty  Agreement") is made and entered into
this 20th day of April, 2000 by Network Consulting Group, Inc. ("Guarantor"), in
favor of VDC Communications, Inc. ("Lender").

                                   WITNESSETH:
                                   -----------

     WHEREAS,   concurrently  herewith,  Rare  Telephony,   Inc.  (f/k/a  Washoe
Technology  Corporation) and Cash Back Rebates LD.com,  Inc. Nevada and Delaware
corporations respectively ("Borrower"),  have executed a certain Promissory Note
in favor of Lender  in the  stated  principal  amount  of Two  Hundred  Thousand
Dollars ($200,000) (the "Note"); and

     WHEREAS,  to  induce  Lender  to lend  the  Two  Hundred  Thousand  Dollars
($200,000)  to  Borrower,  Guarantor  has  agreed to  guarantee  the Note  which
Guaranty is  collaterally  secured by certain  property which is referenced in a
security agreement by and between Guarantor and Lender;

     NOW,  THEREFORE,  in  consideration  of the premises and for other good and
valuable  consideration,  the  receipt  and  sufficiency  of  which  are  hereby
acknowledged, the parties hereby covenant and agree as follows:

     1. Guarantor  irrevocably and  unconditionally,  fully guarantees to Lender
the full and  prompt  payment  of the  indebtedness  evidenced  by the Note (the
"Indebtedness") at the times and according to the terms expressed.

     Guarantor  agrees that if all or any part of the  Indebtedness  is not paid
according to the tenor thereof,  Guarantor shall, upon demand of Lender, pay the
Indebtedness  in like manner as if the  Indebtedness  constituted the direct and
primary  obligation of Guarantor as provided for herein.  Guarantor's  liability
hereunder shall be IN THE FULL AMOUNT of the Indebtedness.

     2. This Guaranty  Agreement is  irrevocable  and shall remain in full force
and effect  continuously from the date hereof to and until the date on which the
Indebtedness  is  paid  in  full,   whereupon  this  Guaranty   Agreement  shall
automatically terminate ("Termination Date").

     3. Guarantor grants to Lender, in Lender's sole and absolute discretion and
without  notice to  Guarantor,  the power and  authority  to deal in any  lawful
manner  with the  Indebtedness  and,  without  limiting  the  generality  of the
foregoing, the power and authority from time to time:

                                       1
<PAGE>

         (a) To change, amend or modify the Note or any other documents relating
thereto in a non-material way (collectively, the "Loan Documents");

         (b) To discharge or release any person liable under the Loan Documents;

         (c) To take and  hold  security  for the  payment  of the  Indebtedness
and/or  the  performance  of the other  obligations  guaranteed  herein,  and to
exchange, enforce, subordinate, waive or release any such security;

         (d) To foreclose any security for the  Indebtedness,  and to direct the
order or manner of sale of any such  security  as  Lender in  Lender's  sole and
absolute discretion may determine;

         (e) To grant any  extensions  of time,  renewals or other  indulgences,
forbearance,  waivers or releases to Borrower or any other  person  liable under
the Loan Documents.

         (f) To  accept  or make  compositions  or other  alignments  or file or
refrain  from filing a claim in any  bankruptcy  proceedings  of Borrower or any
other person liable under the Loan Documents;

         (g) To credit  payments on the  Indebtedness in such manner and in such
order of  priority  as  Lender  may  determine  in  lender's  sole and  absolute
discretion; and

         (h) To otherwise  deal with  Borrower or any other  guarantor or person
related to the  Indebtedness or any security as Lender may determine in Lender's
sole and absolute discretion.

     Without limiting the generality of the foregoing,  Guarantor WAIVES any and
all rights,  benefits and defenses  under law which may provide that a surety is
exonerated if a creditor, without the consent of the surety, alters the original
obligation  of the  principal  in any  respect,  or if the  creditor  in any way
imperils or suspends the creditor's rights against the principal.

     The liability of Guarantor shall not be terminated,  affected,  impaired or
reduced in any way by any action taken by Lender under the foregoing  provisions
or any other provision  hereof or by any delay,  failure or refusal of Lender to
exercise  any right or remedy  Lender  may have  against  Borrower  or any other
person,  including other  guarantors,  if any, liable for all or any part of the
Indebtedness hereby guaranteed.

     4. If at any time  all or any  part of any  payment  made by  Guarantor  or
received  by  Lender  from  Guarantor  under or with  respect  to this  Guaranty

                                       2
<PAGE>

Agreement  is avoided or  recovered  directly  or  indirectly  from  Lender as a
preference,  fraudulent  transfer,  or otherwise,  then Guarantor's  obligations
hereunder shall, to the extent of the payment avoided or recovered, be deemed to
have  continued in  existence,  notwithstanding  such  previous  payment made by
Guarantor or receipt of payment by Lender, and Guarantor's obligations hereunder
shall continue to be effective or be reinstated,  as the case may be, as to such
payment,  all as though such previous  payment by Guarantor had never been made,
irrespective of the payment in full of the Indebtedness.

     5. To the fullest  extent  permitted by law,  Guarantor  hereby  WAIVES the
following rights, defenses and benefits:

         a. The defense of the statute of limitations in any action hereunder or
in any action for the collection of the  Indebtedness  or the performance of any
other obligation hereby guaranteed;

         b. Any  defense  that may arise by reason  of the  incapacity,  lack of
authority,  death or disability of any other person or persons or the failure of
Lender  to file or  enforce  a claim  against  the  estate  (in  administration,
bankruptcy or any other proceeding) of any other person or persons

         c. Except as  otherwise  provided  herein,  diligence  and all demands,
presentment for payment,  notice of nonpayment,  protest,  notice of protest and
all other notices of any kind, including, without limiting the generality of the
foregoing,  notice  of the  existence,  creation  or  incurring  of  any  new or
additional  obligation  or of any action or  nonaction  on the part of Borrower,
Lender,  any  endorser or creditor of Borrower or of Guarantor or on the part of
any other person  whomsoever  under this or any other  instrument  in connection
with  any  Indebtedness  or  evidence  of  Indebtedness  held  by  Lender  or in
connection with the Indebtedness hereby guaranteed;

         d. Any duty or obligation on Lender's part to perfect,  protect, retain
or enforce any security for the payment of the  Indebtedness  or the performance
of any of the other obligations guaranteed herein;

         e. Any duty on the part of Lender to  disclose to  Guarantor  any facts
Lender may now or hereafter  know about  Borrower,  regardless of whether Lender
has reason to believe  that any such facts  materially  increase the risk beyond
that which Guarantor  intends to assume or has reason to believe that such facts
are unknown to Guarantor or has a reasonable  opportunity  to  communicate  such
facts to  Guarantor,  it being  understood  and agreed that  Guarantor  is fully
responsible  for  being and  keeping  informed  of the  financial  condition  of

                                       3
<PAGE>

Borrower and of any and all circumstances bearing on the risk that liability may
be incurred by Guarantor hereunder; and

         f. Any and all rights,  benefits  and defenses  under law  available to
guarantors or sureties, including without limitations, any such rights, benefits
or defenses which would otherwise  require Lender to proceed against Borrower or
any other person,  or to proceed  against or exhaust any security held by Lender
at any time,  or to first apply any security of Borrower to the discharge of the
Indebtedness,  or to pursue any other remedy in Lender's power before proceeding
against Guarantor hereunder.

     6. Guarantor  agrees  that  Guarantor  shall have no right of  subrogation,
reimbursement, exoneration, contribution, indemnity, or similar right as against
Borrower  which would  result in  Guarantor  being deemed a creditor of Borrower
under the Federal Bankruptcy Code or any other law or for any other purpose; and
Guarantor  further  WAIVES any and all rights,  benefits and defenses under law,
which may provide that a surety is entitled to the benefit of every security for
the performance of the principal obligation held by the creditor.

     7. With or without  notice to  Guarantor  and without  affecting in any way
Guarantor's  obligation or liability  hereunder for payment of the Indebtedness,
Lender, in Lender's sole and absolute  discretion,  at any time and from time to
time, and in such manner and upon such terms as Lender deems fit, may:

         a. Apply any or all payments or  recoveries  from  Borrower or from all
other  guarantor or endorser  under any other  instrument  or realized  from any
security,  in such  manner  and order of  priority  as lender may  determine  in
Lender's  sole and  absolute  discretion,  to any  Indebtedness  of  Borrower to
Lender,  whether or not such  Indebtedness is guaranteed  hereby or is otherwise
secured or is due at the time of such application; or

         b.  Refund  to  Borrower  any  payment  received  by  Lender  upon  the
Indebtedness hereby guaranteed.

     8. All rights,  powers and remedies of Lender hereunder shall be cumulative
and not alternative and such rights, powers and remedies shall be in addition to
all  rights,  powers  and  remedies  given to lender  under  the Loan  Documents
(including any other guarantees of the Indebtedness) or otherwise by law.

     9. The  liability of Guarantor  under this Guaranty  Agreement  shall be an
absolute,  direct,  immediate and unconditional  guarantee of payment and not of
collection.  The  Indebtedness  of Guarantor  hereunder are  independent  of the
Indebtedness  of  Borrower  and are  not  conditioned  on  contingent  upon  the
genuineness,   validity,  regularity  or  enforceability  of  any  of  the  Loan
Documents.  In the event of any default hereunder,  a separate action or actions

                                       4
<PAGE>

may be brought and  prosecuted  against  Guarantor,  whether or not  Borrower is
joined  therein or a separate  action or actions are brought  against  Borrower.
Lender may enforce  Lender's rights under the Guaranty  Agreement  without first
exercising  any other  remedy or right that Lender may have or seeking to obtain
payment or  performance  from  Borrower,  any other person  (including any other
guarantor)  or from any  collateral  which  Lender may hold as security  for the
Indebtedness.  Lender  may  maintain  successive  actions  for  other  defaults.
Lender's  rights  hereunder  shall not be  exhausted  by the  exercise of any of
Lender's rights or remedies or by any such action or by any number of successive
actions.  Guarantor  WAIVES any and all rights,  benefits and defenses under law
which may  generally  provide  that a  guarantor  or surety is not liable if for
certain  reasons there is no liability  upon the part of the principal or if the
principal  ceases to  become  liable or which  may  generally  provide  that the
Indebtedness  of a guarantor  or surety  must not be larger nor more  burdensome
than that of the principal.

     10.  Notwithstanding  the fact that Borrower may be a corporation,  a joint
venture or a  partnership,  Lender is not to be concerned to see or inquire into
the powers of Borrower,  its  directors,  officers,  joint  ventures,  partners,
associates  or other  agents  acting or  purporting  to act on its  behalf,  and
Guarantor  expressly  waives any  defense to the  enforcement  of this  Guaranty
Agreement to the effect that the transaction  between  Borrower and Lender is in
excess  of the  powers  of the  Borrower,  or  shall  be in any  way  irregular,
defective or informal.  Guarantor's liability hereunder shall not be affected by
changes in the name of the entity or the constituent members of the entity which
constitutes Borrower.

     11. It is expressly  understood that the obligations of Guarantor hereunder
are an additional and cumulative benefit given to Lender for Lender's security.

     12.  No action based on this Guaranty  Agreement shall be instituted  until
written demand for payment or performance,  as  appropriate,  has been made upon
Guarantor (a) upon delivery of such demand in person to Guarantor, or (b) on the
next business day following  deposit of an envelope  containing such demand with
an overnight  courier  service (such as United  Parcel  Service) for delivery to
Guarantor at the address set forth next to Guarantor's  signature hereon, or (c)
on the second  business day  following  deposit of an envelope  containing  such
demand  in  the  United   States  mail,   postage   prepaid,   certified   mail,
return-receipt  requested,  addressed to Guarantor as described above. Guarantor
may change  Guarantor's  address for such notices by giving notice of the change
of address to Lender in the manner provided herein. All payments hereunder shall
be made in lawful  money of the  United  States of  America.  No delay in making
demand on Guarantor for satisfaction of Guarantor's  liabilities hereunder shall
prejudice Lender's right to enforce such satisfaction.

                                       5
<PAGE>

     13.  Guarantor  shall pay to Lender,  upon written  demand,  all reasonable
attorneys'  fees (including an allocable  portion of in-house  counsel fees) and
all costs and other  expenses  which Lender  expends or incurs in enforcing this
Guaranty  Agreement against  Guarantor whether or not suit is filed,  including,
without  limitation,  all  reasonable  attorneys'  fees  (including an allocable
portion of in-house  counsel  fees),  costs and  expenses  incurred by Lender in
connection with any insolvency, bankruptcy, reorganization, arrangement or other
similar proceedings  involving Borrower or Guarantor which in any way affect the
exercise  by Lender of Lender's  rights and  remedies  hereunder.  Until paid to
Lender, such attorneys' fees (including an allocable portion of in-house counsel
fees),  costs and expenses  shall bear  interest at the highest rate of interest
allowable by law.

     14.  Should  any  one or more  provisions  of this  Guaranty  Agreement  be
determined to be illegal or  unenforceable,  all other  provisions  nevertheless
shall be effective.

     15.  No provision of this Guaranty  Agreement or right of Lender  hereunder
can  be  waived  nor  shall  Guarantor  be  released  from  any  of  Guarantor's
obligations  hereunder  except by a writing duly  executed by Lender,  or unless
this Guaranty  Agreement  terminates  pursuant to its terms as set forth herein.
This Guaranty Agreement may not be modified, amended, revised, changed or varied
in any way whatsoever  except by the express terms of a writing duly executed by
Lender and Guarantor.

     16.  When the context and construction  so requires,  all words used in the
singular  herein  shall be  deemed  to have  been  used in the  plural,  and the
masculine  shall  include  the  feminine  and neuter,  and vice versa.  The word
"person"  as  used  herein  shall  include  any   individual,   company,   firm,
association,  partnership,  corporation, trust or other legal entity of any kind
whatsoever.  The word  "Borrower"  as used herein  includes  Borrower  acting on
behalf of itself or any estate created by the  commencement  of a case under the
Federal Bankruptcy Code or any other insolvency,  bankruptcy,  reorganization or
liquidation  proceeding,  or by any trustee under the Federal  Bankruptcy  Code,
liquidator,  sequestrator,  and receiver of Borrower and Borrower's  property or
similar  person duly  appointed  pursuant to any laws  generally  governing  any
insolvency,  bankruptcy,  reorganization,   liquidation,  receivership  or  like
proceeding.  If more than one person  has  signed  this  Guaranty  Agreement  as
Guarantor,  it shall be the joint and several  obligation  of each of them.  The
words "Loan  Documents" as used herein  include any  modifications,  extensions,
renewals,  or  replacements  thereof.  All  references to statutes  herein shall
include any modifications, amendments, substitutions or replacements thereof.

     17. In the event that all or any part of the  Indebtedness  is  assigned by
Lender,  this Guaranty  Agreement shall  automatically be assigned  therewith in
whole or in part, as applicable, without the need of any express assignment and,

                                       6
<PAGE>

when so assigned,  Guarantor shall be bound as above to the assignee(s)  without
in any manner  affecting  Guarantor's  liability  hereunder  for any part of the
Indebtedness retained by Lender.

     18.  Guarantor  agrees,  within seven (7) calendar  days after request from
Lender, to deliver to Lender a statement certifying that this Guaranty Agreement
is in full force and effect, and that no defense of offset exists to Guarantor's
obligations under the Guaranty Agreement (or stating any facts to the contrary).

     19.  This  Guaranty  Agreement  shall  inure to the benefit of and bind the
heirs, legal representatives, administrators, executors, successors, and assigns
of Lender and of Guarantor.

     20. Guarantor hereby agrees that:

         a. The execution  and delivery to Lender of this Guaranty  Agreement of
the  accrual  of a claim  hereunder  in favor of Lender  shall be deemed to have
caused an event to occur in the State of New Jersey,  bringing  Guarantor within
the jurisdiction of the state and federal courts in the State of New Jersey, and
Guarantor further hereby agrees to and, as a separate and independent  covenant,
does hereby submit to the  jurisdiction  of the state and federal  courts in the
State of New Jersey; and

         b. This  Guaranty  Agreement is made in the State of New Jersey and the
provisions hereof shall be construed and enforced in accordance with the laws of
the State of New Jersey  (irrespective  of its  conflicts of laws rules) and, to
the extent that federal law may preempt the applicability of state laws, federal
law.

     21. Except as provided in any other written agreement at any time hereafter
in force between Lender and Guarantor,  this Guaranty Agreement shall constitute
the entire agreement of Guarantor with Lender with respect to the subject matter
hereof and no representation, understanding, promise or condition concerning the
subject matter hereof shall be binding upon Lender unless expressed herein.

     22. Notwithstanding anything in this Guaranty Agreement to the contrary, it
is agreed that this is a fully "collateralized" guaranty.

                           PERSONAL GUARANTY AGREEMENT
                           ---------------------------

     THIS GUARANTY  AGREEMENT  ("Guaranty  Agreement")  is made and entered into
this 20th day of April, 2000 by Peter J. Salzano ("Guarantor"),  in favor of VDC
Communications, Inc. ("Lender").

                                   WITNESSETH:
                                   -----------

     WHEREAS,   concurrently  herewith,  Rare  Telephony,   Inc.  (f/k/a  Washoe
Technology  Corporation) and Cash Back Rebates LD.com,  Inc. Nevada and Delaware
corporations respectively ("Borrower"),  have executed a certain Promissory Note
in favor of Lender  in the  stated  principal  amount  of Two  Hundred  Thousand
Dollars ($200,000) (the "Note"); and

     WHEREAS,  to  induce  Lender  to lend  the  Two  Hundred  Thousand  Dollars
($200,000)  to  Borrower,  Guarantor  has  agreed to  guarantee  the Note  which
Guaranty is  collaterally  secured by certain  property which is referenced in a
security agreement by and between Guarantor and Lender;

     NOW,  THEREFORE,  in  consideration  of the premises and for other good and
valuable  consideration,  the  receipt  and  sufficiency  of  which  are  hereby
acknowledged, the parties hereby covenant and agree as follows:

     1. Guarantor  irrevocably and  unconditionally,  fully guarantees to Lender
the full and  prompt  payment  of the  indebtedness  evidenced  by the Note (the
"Indebtedness") at the times and according to the terms expressed.

     Guarantor  agrees that if all or any part of the  Indebtedness  is not paid
according to the tenor thereof,  Guarantor shall, upon demand of Lender, pay the
Indebtedness  in like manner as if the  Indebtedness  constituted the direct and
primary  obligation  of Guarantor as provided for herein.  Guarantor's  personal
liability hereunder shall be IN THE FULL AMOUNT of the Indebtedness.

     2. This Guaranty  Agreement is  irrevocable  and shall remain in full force
and effect  continuously from the date hereof to and until the date on which the
Indebtedness  is  paid  in  full,   whereupon  this  Guaranty   Agreement  shall
automatically terminate ("Termination Date").

     3. Guarantor grants to Lender, in Lender's sole and absolute discretion and
without  notice to  Guarantor,  the power and  authority  to deal in any  lawful
manner  with the  Indebtedness  and,  without  limiting  the  generality  of the
foregoing, the power and authority from time to time:

                                       1
<PAGE>

         (a) To change, amend or modify the Note or any other documents relating
thereto in a non-material way (collectively, the "Loan Documents");

         (b) To discharge or release any person liable under the Loan Documents;

         (c) To take and  hold  security  for the  payment  of the  Indebtedness
and/or  the  performance  of the other  obligations  guaranteed  herein,  and to
exchange, enforce, subordinate, waive or release any such security;

         (d) To foreclose any security for the  Indebtedness,  and to direct the
order or manner of sale of any such  security  as  Lender in  Lender's  sole and
absolute discretion may determine;

         (e) To grant any  extensions  of time,  renewals or other  indulgences,
forbearance,  waivers or releases to Borrower or any other  person  liable under
the Loan Documents.

         (f) To  accept  or make  compositions  or other  alignments  or file or
refrain  from filing a claim in any  bankruptcy  proceedings  of Borrower or any
other person liable under the Loan Documents;

         (g) To credit  payments on the  Indebtedness in such manner and in such
order of  priority  as  Lender  may  determine  in  lender's  sole and  absolute
discretion; and

         (h) To otherwise  deal with  Borrower or any other  guarantor or person
related to the  Indebtedness or any security as Lender may determine in Lender's
sole and absolute discretion.

     Without limiting the generality of the foregoing,  Guarantor WAIVES any and
all rights,  benefits and defenses  under law which may provide that a surety is
exonerated if a creditor, without the consent of the surety, alters the original
obligation  of the  principal  in any  respect,  or if the  creditor  in any way
imperils or suspends the creditor's rights against the principal.

     The liability of Guarantor shall not be terminated,  affected,  impaired or
reduced in any way by any action taken by Lender under the foregoing  provisions
or any other provision  hereof or by any delay,  failure or refusal of Lender to
exercise  any right or remedy  Lender  may have  against  Borrower  or any other
person,  including other  guarantors,  if any, liable for all or any part of the
Indebtedness hereby guaranteed.

     4. If at any time  all or any  part of any  payment  made by  Guarantor  or
received  by  Lender  from  Guarantor  under or with  respect  to this  Guaranty
Agreement  is avoided or  recovered  directly  or  indirectly  from  Lender as a

                                       2
<PAGE>

preference,  fraudulent  transfer,  or otherwise,  then Guarantor's  obligations
hereunder shall, to the extent of the payment avoided or recovered, be deemed to
have  continued in  existence,  notwithstanding  such  previous  payment made by
Guarantor or receipt of payment by Lender, and Guarantor's obligations hereunder
shall continue to be effective or be reinstated,  as the case may be, as to such
payment,  all as though such previous  payment by Guarantor had never been made,
irrespective of the payment in full of the Indebtedness.


     5. To the fullest  extent  permitted by law,  Guarantor  hereby  WAIVES the
following rights, defenses and benefits:

         a. The defense of the statute of limitations in any action hereunder or
in any action for the collection of the  Indebtedness  or the performance of any
other obligation hereby guaranteed;

         b. Any  defense  that may arise by reason  of the  incapacity,  lack of
authority,  death or disability of any other person or persons or the failure of
Lender  to file or  enforce  a claim  against  the  estate  (in  administration,
bankruptcy or any other proceeding) of any other person or persons

         c. Except as  otherwise  provided  herein,  diligence  and all demands,
presentment for payment,  notice of nonpayment,  protest,  notice of protest and
all other notices of any kind, including, without limiting the generality of the
foregoing,  notice  of the  existence,  creation  or  incurring  of  any  new or
additional  obligation  or of any action or  nonaction  on the part of Borrower,
Lender,  any  endorser or creditor of Borrower or of Guarantor or on the part of
any other person  whomsoever  under this or any other  instrument  in connection
with  any  Indebtedness  or  evidence  of  Indebtedness  held  by  Lender  or in
connection with the Indebtedness hereby guaranteed;

         d. Any duty or obligation on Lender's part to perfect,  protect, retain
or enforce any security for the payment of the  Indebtedness  or the performance
of any of the other obligations guaranteed herein;

         e. Any duty on the part of Lender to  disclose to  Guarantor  any facts
Lender may now or hereafter  know about  Borrower,  regardless of whether Lender
has reason to believe  that any such facts  materially  increase the risk beyond
that which Guarantor  intends to assume or has reason to believe that such facts
are unknown to Guarantor or has a reasonable  opportunity  to  communicate  such
facts to  Guarantor,  it being  understood  and agreed that  Guarantor  is fully
responsible  for  being and  keeping  informed  of the  financial  condition  of

                                       3
<PAGE>

Borrower and of any and all circumstances bearing on the risk that liability may
be incurred by Guarantor hereunder; and

         f. Any and all rights,  benefits  and defenses  under law  available to
guarantors or sureties, including without limitations, any such rights, benefits
or defenses which would otherwise  require Lender to proceed against Borrower or
any other person,  or to proceed  against or exhaust any security held by Lender
at any time,  or to first apply any security of Borrower to the discharge of the
Indebtedness,  or to pursue any other remedy in Lender's power before proceeding
against Guarantor hereunder.

     6.  Guarantor  agrees that  Guarantor  shall have no right of  subrogation,
reimbursement, exoneration, contribution, indemnity, or similar right as against
Borrower  which would  result in  Guarantor  being deemed a creditor of Borrower
under the Federal Bankruptcy Code or any other law or for any other purpose; and
Guarantor  further  WAIVES any and all rights,  benefits and defenses under law,
which may provide that a surety is entitled to the benefit of every security for
the performance of the principal obligation held by the creditor.

     7. With or without  notice to  Guarantor  and without  affecting in any way
Guarantor's  obligation or liability  hereunder for payment of the Indebtedness,
Lender, in Lender's sole and absolute  discretion,  at any time and from time to
time, and in such manner and upon such terms as Lender deems fit, may:

     a. Apply any or all payments or recoveries  from Borrower or from all other
guarantor or endorser under any other  instrument or realized from any security,
in such manner and order of priority as lender may  determine  in Lender's  sole
and absolute discretion,  to any Indebtedness of Borrower to Lender,  whether or
not such  Indebtedness is guaranteed hereby or is otherwise secured or is due at
the time of such application; or

     b. Refund to Borrower any payment  received by Lender upon the Indebtedness
hereby guaranteed.

     8. All rights,  powers and remedies of Lender hereunder shall be cumulative
and not alternative and such rights, powers and remedies shall be in addition to
all  rights,  powers  and  remedies  given to lender  under  the Loan  Documents
(including any other guarantees of the Indebtedness) or otherwise by law.

     9. The  liability of Guarantor  under this Guaranty  Agreement  shall be an
absolute,  direct,  immediate and unconditional  guarantee of payment and not of
collection.  The  Indebtedness  of Guarantor  hereunder are  independent  of the
Indebtedness  of  Borrower  and are  not  conditioned  on  contingent  upon  the
genuineness,   validity,  regularity  or  enforceability  of  any  of  the  Loan
Documents.  In the event of any default hereunder,  a separate action or actions

                                       4
<PAGE>

may be brought and  prosecuted  against  Guarantor,  whether or not  Borrower is
joined  therein or a separate  action or actions are brought  against  Borrower.
Lender may enforce  Lender's rights under the Guaranty  Agreement  without first
exercising  any other  remedy or right that Lender may have or seeking to obtain
payment or  performance  from  Borrower,  any other person  (including any other
guarantor)  or from any  collateral  which  Lender may hold as security  for the
Indebtedness.  Lender  may  maintain  successive  actions  for  other  defaults.
Lender's  rights  hereunder  shall not be  exhausted  by the  exercise of any of
Lender's rights or remedies or by any such action or by any number of successive
actions.  Guarantor  WAIVES any and all rights,  benefits and defenses under law
which may  generally  provide  that a  guarantor  or surety is not liable if for
certain  reasons there is no liability  upon the part of the principal or if the
principal  ceases to  become  liable or which  may  generally  provide  that the
Indebtedness  of a guarantor  or surety  must not be larger nor more  burdensome
than that of the principal.

     10.  Notwithstanding  the fact that Borrower may be a corporation,  a joint
venture or a  partnership,  Lender is not to be concerned to see or inquire into
the powers of Borrower,  its  directors,  officers,  joint  ventures,  partners,
associates  or other  agents  acting or  purporting  to act on its  behalf,  and
Guarantor  expressly  waives any  defense to the  enforcement  of this  Guaranty
Agreement to the effect that the transaction  between  Borrower and Lender is in
excess  of the  powers  of the  Borrower,  or  shall  be in any  way  irregular,
defective or informal.  Guarantor's liability hereunder shall not be affected by
changes in the name of the entity or the constituent members of the entity which
constitutes Borrower.

     11. It is expressly  understood that the obligations of Guarantor hereunder
are an additional and cumulative benefit given to Lender for Lender's security.

     12. No action based on this Guaranty  Agreement  shall be instituted  until
written demand for payment or performance,  as  appropriate,  has been made upon
Guarantor (a) upon delivery of such demand in person to Guarantor, or (b) on the
next business day following  deposit of an envelope  containing such demand with
an overnight  courier  service (such as United  Parcel  Service) for delivery to
Guarantor at the address set forth next to Guarantor's  signature hereon, or (c)
on the second  business day  following  deposit of an envelope  containing  such
demand  in  the  United   States  mail,   postage   prepaid,   certified   mail,
return-receipt  requested,  addressed to Guarantor as described above. Guarantor
may change  Guarantor's  address for such notices by giving notice of the change
of address to Lender in the manner provided herein. All payments hereunder shall
be made in lawful  money of the  United  States of  America.  No delay in making
demand on Guarantor for satisfaction of Guarantor's  liabilities hereunder shall
prejudice Lender's right to enforce such satisfaction.

                                       5
<PAGE>

     13.  Guarantor  shall pay to Lender,  upon written  demand,  all reasonable
attorneys'  fees (including an allocable  portion of in-house  counsel fees) and
all costs and other  expenses  which Lender  expends or incurs in enforcing this
Guaranty  Agreement against  Guarantor whether or not suit is filed,  including,
without  limitation,  all  reasonable  attorneys'  fees  (including an allocable
portion of in-house  counsel  fees),  costs and  expenses  incurred by Lender in
connection with any insolvency, bankruptcy, reorganization, arrangement or other
similar proceedings  involving Borrower or Guarantor which in any way affect the
exercise  by Lender of Lender's  rights and  remedies  hereunder.  Until paid to
Lender, such attorneys' fees (including an allocable portion of in-house counsel
fees),  costs and expenses  shall bear  interest at the highest rate of interest
allowable by law.

     14. Should   any  one or more  provisions  of this  Guaranty  Agreement  be
determined to be illegal or  unenforceable,  all other  provisions  nevertheless
shall be effective.

     15. No provision of this  Guaranty  Agreement or right of Lender  hereunder
can  be  waived  nor  shall  Guarantor  be  released  from  any  of  Guarantor's
obligations  hereunder  except by a writing duly  executed by Lender,  or unless
this Guaranty  Agreement  terminates  pursuant to its terms as set forth herein.
This Guaranty Agreement may not be modified, amended, revised, changed or varied
in any way whatsoever  except by the express terms of a writing duly executed by
Lender and Guarantor.

     16. When the context and  construction  so requires,  all words used in the
singular  herein  shall be  deemed  to have  been  used in the  plural,  and the
masculine  shall  include  the  feminine  and neuter,  and vice versa.  The word
"person"  as  used  herein  shall  include  any   individual,   company,   firm,
association,  partnership,  corporation, trust or other legal entity of any kind
whatsoever.  The word  "Borrower"  as used herein  includes  Borrower  acting on
behalf of itself or any estate created by the  commencement  of a case under the
Federal Bankruptcy Code or any other insolvency,  bankruptcy,  reorganization or
liquidation  proceeding,  or by any trustee under the Federal  Bankruptcy  Code,
liquidator,  sequestrator,  and receiver of Borrower and Borrower's  property or
similar  person duly  appointed  pursuant to any laws  generally  governing  any
insolvency,  bankruptcy,  reorganization,   liquidation,  receivership  or  like
proceeding.  If more than one person  has  signed  this  Guaranty  Agreement  as
Guarantor,  it shall be the joint and several  obligation  of each of them.  The
words "Loan  Documents" as used herein  include any  modifications,  extensions,

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

     THIS SECURITY  AGREEMENT  ("Agreement")  is made and entered into this 20th
day of  April,  2000,  by and  between  VDC  Communications,  Inc.,  a  Delaware
corporation ("Secured Party"), and Network Consulting Group, Inc., ("Pledgor").

     RECITALS
     --------

     A. Concurrently  herewith,  Rare  Telephony, Inc. (f/k/a/ Washoe Technology
Corporation)  and Cash Back Rebates LD.com,  Inc.  ("Borrower")  have executed a
certain  Promissory  Note (the  "Note")  in the stated  principal  amount of Two
Hundred Thousand Dollars ($200,000) in favor of the Secured Party.

     B. Also  concurrently  herewith,  Pledgor has  executed in favor of Secured
Party a certain Guaranty  Agreement (the  "Guaranty")  pursuant to which Pledgor
has guaranteed the indebtedness of Borrower, to Secured Party under the Note.

     C. The  indebtedness  of Pledgor to the Secured Party under the Guaranty is
hereinafter collectively referred to as the "Indebtedness".

     D. It is the purpose and intent of the parties hereto to secure the payment
by  Pledgor  to  Secured  Party  of the  Indebtedness  by a  pledge  of  certain
collateral, according to the terms and conditions set forth herein.

     NOW,  THEREFORE,  in consideration of the premises and the mutual covenants
and conditions set forth herein, the parties agree as follows:

     1. Pledgor  hereby  grants to Secured  Party a security  interest in and to
6,250  shares  of the  common  stock  of Rare  Telephony,  Inc.  (f/k/a/  Washoe
Technology  Corporation) evidenced by Share Certificate No. 8 ("Collateral") and
does hereby deliver to and deposit the Collateral  with Secured Party,  together
with a stock power duly executed in blank.

     During the term hereof,  and subject to the  provisions of this  Agreement,
Secured Party shall hold and retain the Collateral for the purpose of perfecting
the security  interest  herein granted to Secured Party,  and for the purpose of
carrying out the provisions of this Agreement.

     2. The Collateral shall secure the payment of the Indebtedness.

     3. Pledgor warrants that Pledgor is the sole lawful owner of the Collateral
and that there is no lien or charge against, or encumbrance or security interest
in, or adverse claim to, the Collateral,  or any portion thereof, other than the

                                       1
<PAGE>

security  interest created  pursuant to this Agreement.  So long as there is any
Indebtedness  whatsoever  owing to  Secured  Party,  Pledgor  agrees to keep the
Collateral free and clear of any and all liens, encumbrances, security interests
(other  than  the  security  interest  of  Secured  Party),  adverse  claims  or
interests.

     4. As  long  as  Pledgor  is not in  default  hereunder,  any and all  cash
dividends or other property (but not stock  dividends)  which may be received by
Secured  Party  during  the  term of  this  Agreement  which  derives  from  the
Collateral  shall be remitted to Pledgor,  and Pledgor  shall  retain all voting
rights  associated  with the  Collateral.  Any cash  dividends or other property
received  with  respect  to the  Collateral  after the  occurrence  of a default
hereunder  shall  be  delivered  to and  held by  Secured  Party  as  additional
Collateral,  and after the  occurrence of such default  Secured Party shall have
all voting rights associated with the Collateral.

     5. Pledgor shall be in default under this  Agreement  upon the happening of
any of the following events:

              (a) Pledgor fails to pay any portion of the Indebtedness when due;

              (b) Borrower commits a default under the Note or Pledgor commits a
default under the Guaranty;

              (c) Pledgor fails to perform any other agreement or covenant under
this Agreement  within any applicable  notice and/or "grace"  periods  specified
herein, provided that if no notice or grace period is herein specified,  Pledgor
shall have ten (10)  calendar  days after  notice  thereof has been given within
which to cure any such default;

              (d) All or a majority of the value of the Collateral or the assets
of  Borrower  is  seized  or  levied  upon by writ of  attachment,  garnishment,
execution or otherwise,  and such seizure or levy is not released  within thirty
(30) calendar days thereafter;

              (e) Either Pledgor or Borrower  executes a general  assignment for
the benefit of its  creditors,  convenes any meeting of its  creditors,  becomes
insolvent, admits in writing its insolvency or inability to pay its debts, or is
unable to pay or is generally not paying its debts as they become due;

              (f) A receiver,  trustee,  custodian or agent is appointed to take
possession  of all or any portion of the  Collateral  or all or any  substantial
potion of Pledgor's or Borrower's assets;

                                       2
<PAGE>

              (g) Any case or proceeding is voluntarily  commenced by Pledgor or
Borrower under any provision of the federal Bankruptcy Code or any other federal
or  state  law  relating  to  debtor  rehabilitation,   insolvency,  bankruptcy,
liquidation, or reorganization,  or any such case or proceeding is involuntarily
commenced  against  Pledgor or Borrower  and not  dismissed  within  thirty (30)
calendar days thereafter;

              (h) Any representation made by Pledgor in this Agreement or in any
of the other documents delivered in connection therewith, shall have been untrue
or incorrect in any material respect when made.

     Upon  such  default,   Secured  Party  may,  at  its  option,  declare  all
Indebtedness  to be  immediately  due and payable.  Additionally,  Secured Party
shall have the rights and remedies set forth in Paragraph 6 below.

     6. Should Pledgor  default under this  Agreement,  Secured Party shall have
all rights and remedies  afforded a secured  party under the Uniform  Commercial
Code of New Jersey and may, in connection therewith, also:

              (a) Sell,  lease, or otherwise dispose of the Collateral at public
or private sale, in one or more sales, as a unit or in parcels,  at wholesale or
retail,  and at such  time and  place  and on such  terms as  Secured  Party may
determine. Secured Party may be the purchaser or any or all of the Collateral at
any public or private sale.  If, at any time when Secured Party shall  determine
to  exercise  its  right  to sell  all or any  part of the  Collateral  and such
Collateral, or the part thereof to be sold, it has been advised by legal counsel
that the  Collateral is subject to the  Securities Act of 1933 as amended or any
state securities  laws,  Secured Party in its sole and absolute  discretion,  is
hereby  expressly  authorized  to sell  such  Collateral,  or any part  thereof,
subject to obtaining all required regulatory approvals,  by private sale in such
manner  and under such  circumstances  as Secured  Party may deem  necessary  or
advisable in order that such sale may be effected  legally without  registration
or  qualification  under  applicable   securities  laws.  Without  limiting  the
generality of the foregoing,  Secured Party, in it sole and absolute discretion,
may approach and negotiate with a restricted  number of potential  purchasers to
effect such sale or  restrict  such sale to a purchaser  or  purchaser  who will
represent and agree that such  purchaser or purchasers are purchasing for his or
their own account,  for investment only, and not with a view of the distribution
or sale of such Collateral or any part thereof. Any such sale shall be deemed to
be a sale made in a  commercially  reasonable  manner  within the meaning of the
Uniform  Commercial  Code of the State of New Jersey and Pledgor hereby consents
and agrees that Secured  Party shall incur no  responsibility  or liability  for
selling all or any part of the  Collateral at a price which is not  unreasonably
low,  notwithstanding  the possibility  that a higher price might be realized if

                                       3
<PAGE>

the sale were  public.  Any public sale of any or all of the  Collateral  may be
postponed  from time to time by public  announcement  at the time and place last
scheduled for the sale.  Without  limiting the  generality of this Section 6, it
shall conclusively be deemed to be commercially  reasonable for Secured Party to
direct any  prospective  purchaser of any or all of the Collateral to Pledgor to
ascertain all information  concerning the status of Borrower.  Securing  Party's
disposition of any or all of the Collateral in any manner which differs from the
procedures  specified in this  Section 6 shall not be deemed to be  commercially
unreasonable; or

         (b)  Propose  to accept  the  Collateral  after  giving  notice of such
proposal  to Pledgor  and to any other  person  with a security  interest in the
Collateral in accordance with the Uniform  Commercial Code of New Jersey, or any
applicable successor statute.  Such acceptance shall discharge the obligation of
Pledgor and the  Corporation  with respect to the  Indebtedness,  provided  that
neither Pledgor nor any other person with a security  interest in the Collateral
objects in writing to such a proposal within twenty one (21) calendar days after
receipt of such notice.

     The  proceeds of any sale,  lease or other  disposition  of the  Collateral
shall be applied in the manner and priority set forth in the Uniform  Commercial
Code of New Jersey, or any applicable successor statute.

     7. Pledgor  unconditionally  agrees upon demand to pay to the Secured Party
the amount of any and all reasonable and necessary out-of-pocket costs, expenses
and disbursements, including fees and expenses of its counsel, which the Secured
Party may incur in connection  with (i) the  administration  of this  Agreement,
(ii) the custody,  preservation, use or operation of, or the sale of, collection
from,  or  other  realization  upon,  the  Collateral,  (iii)  the  exercise  or
enforcement  of any of the rights of the  Secured  Party  hereunder  or (iv) the
failure by Pledgor to perform or observe any of the provisions  hereof.  Pledgor
unconditionally  agrees to indemnify  the Secured Party from and against any and
all  claims,  losses  and  liabilities  arising  out of or  resulting  from this
Agreement (including  enforcement of this Agreement),  except claims,  losses or
liabilities  resulting  from the gross  negligence or willful  misconduct of the
Secured Party.

     8. Pledgor waives any right to require the Secured Party to:

              (a) Proceed against any person;

              (b) Proceed against or exhaust any collateral; or

              (c) Pursue any other remedy in Secured Party's power.

                                       4
<PAGE>

     Pledgor further authorizes the Secured Party,  without notice or demand and
without affecting its liability  hereunder or on the Indebtedness,  from time to
time to:

         (d)  Amend  or  modify  the  terms  of the  Note or the  Guaranty  with
Pledgor's  consent,  including,  but not  limited  to,  any  such  amendment  or
modification which affects the Indebtedness.

         (e) Take and hold security, other than the Collateral herein described,
for the payment of the Indebtedness or any part thereof, and exchange,  enforce,
waive,  and release the Collateral  herein  described or any part thereof or any
such other security.

         (f) Apply such  Collateral  or other  security  and direct the order or
manner of sale thereof as Secured Party in its discretion may determine.

     9. In the event that any additional shares of capital stock of Borrower are
issued  to or  acquired  by  Pledgor  during  the term of this  Agreement,  such
additional  shares shall be  considered  additional  Collateral  subject to this
Agreement,  and Pledgor shall immediately deliver stock certificates  evidencing
such  additional  shares of  capital  stock and duly  executed  stock  powers to
Secured Party.

     10. Neither the acceptance of any partial or delinquent  payment by Secured
Party nor Secured  Party's  failure to exercise any of its rights or remedies on
default by Pledgor  shall be a waiver of the  default,  a  modification  of this
Agreement  or Pledgor's  obligations  under this  Agreement,  or a waiver of any
subsequent default by Pledgor.

     11. All notices  are  required or  permitted  to be given  pursuant to this
Agreement  shall be in writing,  and shall be delivered  either  personally,  by
overnight  delivery  service or by U.S.  certified or registered  mail,  postage

         WHEREAS,  It is the purpose and intent of the parties  hereto to secure

to the terms and conditions set forth herein.

         NOW,  THEREFORE,  intending  to be legally  bound  hereby and for value
received, the parties hereto covenant and agree as follows:

         1.       Definitions.  In  addition  to  the  words  and  terms defined

                  (b)      "Collateral" shall  mean,  all  of  Grantor's  right,
title and interest in, to and under the following  described  property,  whether

         2.       Assignment and Grant  of  Security Interests.  As security for
                  ---------------------------------------------
the due and punctual  payment and  performance  of the Secured  Indebtedness  in
full,  Grantor  hereby  agrees  that the Secured  Party shall have,  and Grantor
hereby grants to and creates in favor of the Secured  Party,  for the benefit of
the Secured Party, to secure all of the Secured Indebtedness, a continuing first
priority  security  interest  (or,  alternatively,  as high a priority  security

                                       3
<PAGE>

interest  as is  permitted  by  law)  in and to  Grantor's  Collateral.  Without
limiting the  generality of Section 4 below,  Grantor  further  agrees that with
respect to each item of  Collateral  as to which (i) the  creation  of valid and
enforceable  security interests is not governed  exclusively by the Code or (ii)
the perfection of valid and  enforceable  security  interests  therein under the
Code cannot be accomplished by the Secured Party taking possession thereof or by
the filing in  appropriate  locations of appropriate  Code financing  statements
executed by the Grantor,  Grantor will at its expense execute and deliver to the
Secured Party such documents,  agreements,  notices, assignments and instruments
and take such  further  actions as may be  reasonably  requested  by the Secured
Party from time to time for the purpose of creating a valid and perfected  first
priority lien (or,  alternatively,  as high a priority  security  interest as is
permitted  by law) on such item,  enforceable  against the Grantor and all third
parties to secure the Secured Indebtedness.

         3.       Representations and Warranties.  Grantor  represents, warrants
                  -------------------------------
and covenants to the Secured Party that:

                  (a)      Grantor is the legal and  beneficial owner and holder
of the  Collateral and Grantor has and will continue to have good and marketable
title to the Collateral  which Grantor  purports to own or which is reflected as
owned in its books and records.

                  (b)      The Grantor has received value from the Secured Party
for Grantor's grant of security interests hereunder and, except for the security
interests granted to and created in favor of the Secured Party hereunder, all of
the  Collateral is and will  continue to be free and clear of all liens,  except
any lien possessed by the Secured Party (the "Permitted Lien").

                  (c)      Grantor  has  full  power  to  enter  into,  execute,
deliver and carry out this  Security  Agreement  and to perform its  obligations
hereunder  and all such  actions  have been  duly  authorized  by all  necessary
proceedings  on its part.  This  Security  Agreement  has been duly and  validly
executed and  delivered by Grantor.  This  Security  Agreement  constitutes  the
legal,  valid and  binding  obligations  of Grantor,  enforceable  against it in
accordance  with its terms,  except to the  extent  that  enforceability  may be
limited by bankruptcy, insolvency,  reorganization,  moratorium or other similar
laws affecting the enforceability of creditors' rights generally or limiting the
right of specific performance.

                  (d)      Neither the execution and delivery  of this  Security
Agreement nor compliance with the terms and provisions  hereof (i) will conflict
with or result in any  breach of the terms and  conditions  of the  articles  of
incorporation,  bylaws or  equivalent  documents of Grantor or of any law or any
material  agreement or  instrument to which Grantor is a party or by which it is
bound or to which it is subject, (ii) will constitute a default under any of the
documents  referred  to in  clause  3(d)(i)  above or (iii)  will  result in the


                                       4
<PAGE>

creation or enforcement of any lien (other than the Permitted  Lien)  whatsoever
upon any Collateral (now or hereafter acquired) of Grantor.

         4.       Further Assurances.  Grantor will,  from  time to time, at its
                  -------------------
expense,  faithfully preserve and protect the Secured Party's security interests
in the Collateral as continuing first priority perfected security interests (or,
alternatively, as high a priority security interest as is permitted by law), and
will do all such other acts and things and will,  upon  request  therefor by the
Secured Party,  execute,  deliver,  file and record all such other documents and
instruments,  including  financing  statements,  security  agreements,  pledges,
assignments,  documents and powers of attorney  with respect to the  Collateral,
and pay all filing fees and taxes  related  thereto as the Secured  Party in its
reasonable discretion may deem necessary or advisable from time to time in order
to preserve, perfect or protect any security interest granted or purported to be
granted hereby or to enable the Secured Party to exercise and enforce its rights
and remedies  hereunder with respect to any of the Collateral.  Without limiting
the  generality of the  foregoing,  to the extent Article 9 of the Code does not
govern the creation and/or perfection of the security  interests  intended to be
created hereunder,  Grantor agrees to execute and deliver such further documents
and  instruments  and do such further acts as the Secured Party may from time to
time require.

         5.       Covenants.  Grantor covenants and agrees that, (a) it will not
                  ----------
sell, assign or otherwise dispose of any portion of the Collateral;  (b) it will
obtain and maintain sole and exclusive possession of its Collateral; (c) it will
keep  materially   accurate  and  complete  books  and  records  concerning  the
Collateral  (d) it will promptly  furnish to the Secured Party such  information
and documents  relating to the  Collateral  as the Secured Party may  reasonably
request in order to confirm the status of the Secured Party's security interests
in such Collateral; (e) it will not take or omit to take any actions, the taking
or the  omission  of which  might  result in a material  adverse  alteration  or
impairment of the Collateral or in a violation of this Security  Agreement;  and
(f) it will execute and deliver to the Secured Party and record such supplements
to this  Security  Agreement  and  additional  assignments  as the Secured Party
reasonably  may request to evidence  and confirm the security  interests  herein
contained.

         6.       Preservation   of  Security   Interests.  Grantor assumes full
                  ----------------------------------------
responsibility  for taking and hereby agrees to take any and all necessary steps
to preserve and defend the Secured Party's right,  title and security  interests
in and to the  Collateral  against  the claims and demands of all  persons.  The
Secured Party shall be deemed to have exercised  reasonable  care in the custody
and  preservation of the Collateral in the Secured Party's  possession if, prior
to the existence of an Event of Default, the Secured Party takes such action for
that purpose as such Grantor shall reasonably request in writing,  provided that
such requested action will not, in the judgment of the Secured Party, impair the
security  interests  in the  Collateral  created  hereby or the Secured  Party's
rights in, or the value of, such  Collateral,  and  provided  further  that such

                                       5
<PAGE>

written  request is received by the Secured Party in  sufficient  time to permit
the Secured Party to take the requested action.

         7.       Secured Party's  Rights  with  Respect to the  Collateral.  At
                  ----------------------------------------------------------
any time and from time to time,  whether or not an Event of  Default  shall have
occurred,  and without  notice to or consent of the Grantor,  the Secured  Party
may, at its option,  do any or all of the  following:  (a) do anything which the
Grantor is required but fails to do  hereunder,  and in  particular  the Secured
Party may,  if the  Grantor  fails to do so,  (i) insure or take any  reasonable
steps to protect the Collateral, (ii) pay any or all taxes, levies, expenses and
costs arising with respect to the  Collateral,  or (iii) pay any or all premiums
payable  on any  policy of  insurance  required  to be  obtained  or  maintained
hereunder, and add any amounts paid under this Section 7 to the principal amount
of the  Note,  and  other  liabilities  of  Grantor  secured  by  this  Security
Agreement;  (b) inspect the Collateral at any  reasonable  time; and (c) pay any
amounts the  Secured  Party  reasonably  elects to pay or advance  hereunder  on
account  of  insurance,  taxes  or  other  costs,  fees or  charges  arising  in
connection  with the  Collateral,  either directly to the payee(s) of such cost,
fee or  charge,  directly  to the  Grantor,  or to such  payee(s)  and  Grantor,
jointly.

         8.       Remedies  on  Default.  If  there  shall  have occurred and be
                  ----------------------
continuing  an Event of Default  under the terms of the Note,  then the  Secured
Party shall have such rights and remedies with respect to the  Collateral or any
part thereof and the proceeds thereof as are provided by the Code and such other
rights and remedies  with respect  thereto which it may have at law or in equity
or under this Security Agreement,  including to the extent not inconsistent with
the provisions of the Code or any other  applicable  law, the right to take over
and collect the  Collateral  which  consists of amounts  owing to Grantor to the
extent not  prohibited by  applicable  law. To this end, the Secured Party shall
have the right to (a) transfer all or any part of any of the Collateral into the
Secured  Party's name or into the name of its nominee or nominees and thereafter
receive all cash, stock and other dividends or distributions  paid or payable in
respect  thereof,  and otherwise act with respect  thereto as the absolute owner
thereof;  (b) notify the obligors on any of the Collateral,  whether accounts or
otherwise, to make payment thereon directly to the Secured Party, whether or not
the Grantor was theretofore making collections  thereon; (c) take control of and
manage the  Collateral;  (d) apply to the payment of the  Secured  Indebtedness,
whether it be due and payable or not, any moneys,  including  cash dividends and
income from the Collateral,  now or hereafter in the hands of the Secured Party,
on deposit or  otherwise,  belonging to Grantor,  in  accordance  with Section 9
hereof;  (e) endorse the name of the Grantor upon any checks or other  evidences
of payment or any document or  instrument  that may come into the  possession of
the Secured Party as proceeds of or relating to such Grantor's  Collateral;  (f)
demand,  sue for, collect,  compromise and give acquittances for the Collateral;
(g) prosecute, defend or compromise any action, claim or proceeding with respect

                                       6
<PAGE>

debtors of Grantor.  In addition,  upon the  occurrence  of an Event of Default,
Grantor,  at the request of the Secured Party, shall assemble all or any portion
of the  Grantor's  Collateral  at such  locations  as the  Secured  Party  shall
designate which are reasonably  convenient to Grantor, and the Secured Party may
sell, assign,  give an option or options to purchase or otherwise dispose of all
or any part of the  Collateral  at any public or  private  sale at such place or
places  and at such time or times and upon such  terms,  whether  for cash or on
credit,  and in such manner,  as the Secured Party may determine,  and apply the
proceeds so received in accordance with Section 9 hereof. Written notice of sale
mailed by certified mail, return receipt requested, to the Grantor, at least ten
(10) calendar days prior to such sale shall be deemed reasonable notice.

                  In the event of a breach by Grantor in the  performance of any
of the terms of this Security  Agreement,  the Secured Party may demand specific
performance  of this  Security  Agreement  and seek  injunctive  relief  and may
exercise any other remedy,  available at law or in equity,  it being  recognized
that the  remedies  of the  Secured  Party at law may not fully  compensate  the
Secured Party for the damages it may suffer in the event of a breach hereof.

         9.       Application of Proceeds.  The proceeds of the Collateral shall
                  ------------------------
be applied to Secured  Indebtedness.  Grantor shall be liable for any deficiency
if the  proceeds  of any sale,  assignment,  giving of an option or  options  to
purchase or other  disposition  of the  Collateral  is  insufficient  to pay all
amounts to which the Secured Party is entitled.

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

or non-perfection of any other Collateral;  or (d) any other  circumstance which
might  otherwise  constitute  a defense  available  to, or a  discharge  of, any

interests.  Grantor  waives any and all notice with respect to acceptance by the
Secured Party of this Security  Agreement,  the provisions of the Note or any of
the Other Documents or any other note,  instrument or agreement  relating to the
Secured   Indebtedness,   and  any  default  in  connection   with  the  Secured
Indebtedness.  Grantor  waives any  presentment,  demand,  notice of dishonor or
nonpayment,  protest,  notice of  protest  and any  other  notice of any kind in

and termination of the Note,  this Security  Agreement shall terminate and be of

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

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

     THIS SECURITY  AGREEMENT  ("Agreement")  is made and entered into this 20th
day of  April,  2000,  by and  between  VDC  Communications,  Inc.,  a  Delaware
corporation ("Secured Party"), and Peter J. Salzano, ("Pledgor").

     RECITALS
     --------

     A.  Concurrently herewith, Rare Telephony, Inc.  (f/k/a/  Washoe Technology
Corporation)  and Cash Back Rebates LD.com,  Inc.  ("Borrower")  have executed a
certain  Promissory  Note (the  "Note")  in the stated  principal  amount of Two
Hundred Thousand Dollars ($200,000) in favor of the Secured Party.

     B.  Also concurrently  herewith,  Pledgor has  executed in favor of Secured
Party a certain Guaranty  Agreement (the  "Guaranty")  pursuant to which Pledgor
has guaranteed the indebtedness of Borrower, to Secured Party under the Note.

     C.  The indebtedness  of Pledgor to the Secured Party under the Guaranty is
hereinafter collectively referred to as the "Indebtedness".

     D.  It is the purpose and intent  of  the  parties  hereto  to  secure  the
payment by Pledgor to Secured Party of the  Indebtedness  by a pledge of certain
collateral, according to the terms and conditions set forth herein.

     NOW,  THEREFORE,  in consideration of the premises and the mutual covenants
and conditions set forth herein, the parties agree as follows:

     1.  Pledgor hereby  grants to Secured  Party a security  interest in and to
2,500  shares  of the  common  stock  of Rare  Telephony,  Inc.  (f/k/a/  Washoe
Technology  Corporation) evidenced by Share Certificate No. 3 ("Collateral") and
does hereby deliver to and deposit the Collateral  with Secured Party,  together
with a stock power duly executed in blank.

     During the term hereof,  and subject to the  provisions of this  Agreement,
Secured Party shall hold and retain the Collateral for the purpose of perfecting
the security  interest  herein granted to Secured Party,  and for the purpose of
carrying out the provisions of this Agreement.

     2.  The Collateral shall secure the payment of the Indebtedness.

     3.  Pledgor  warrants  that  Pledgor  is  the  sole  lawful  owner  of  the
Collateral  and that  there is no lien or  charge  against,  or  encumbrance  or
security  interest  in, or adverse  claim to,  the  Collateral,  or any  portion
thereof, other than the

                                       1
<PAGE>

security  interest created  pursuant to this Agreement.  So long as there is any
Indebtedness  whatsoever  owing to  Secured  Party,  Pledgor  agrees to keep the
Collateral free and clear of any and all liens, encumbrances, security interests
(other  than  the  security  interest  of  Secured  Party),  adverse  claims  or
interests.

     4.  As long  as  Pledgor  is not in  default  hereunder,  any and all  cash
dividends or other property (but not stock  dividends)  which may be received by
Secured  Party  during  the  term of  this  Agreement  which  derives  from  the
Collateral  shall be remitted to Pledgor,  and Pledgor  shall  retain all voting
rights  associated  with the  Collateral.  Any cash  dividends or other property
received  with  respect  to the  Collateral  after the  occurrence  of a default
hereunder  shall  be  delivered  to and  held by  Secured  Party  as  additional
Collateral,  and after the  occurrence of such default  Secured Party shall have
all voting rights associated with the Collateral.

any of the following events:

         (a) Pledgor fails to pay any portion of the Indebtedness when due;

         (b) Borrower  commits a  default  under the Note or  Pledgor  commits a

cure any such default;

         (d) All or a majority of the value of the  Collateral  or the assets of

calendar days thereafter;

         (e) Either  Pledgor or Borrower  executes a general  assignment for the

         (f) A  receiver,  trustee,  custodian  or  agent is  appointed  to take
possession  of all or any portion of the  Collateral  or all or any  substantial
potion of Pledgor's or Borrower's assets;

     6.  Should Pledgor default under this  Agreement,  Secured Party shall have

         (a) Sell,  lease,  or otherwise  dispose of the Collateral at public or
private  sale,  in one or more sales,  as a unit or in parcels,  at wholesale or
retail,  and at such  time and  place  and on such  terms as  Secured  Party may
determine. Secured Party may be the purchaser or any or all of the Collateral at
any public or private sale.  If, at any time when Secured Party shall  determine
to  exercise  its  right  to sell  all or any  part of the  Collateral  and such

manner  and under such  circumstances  as Secured  Party may deem  necessary  or
advisable in order that such sale may be effected  legally without  registration

generality of the foregoing,  Secured Party, in it sole and absolute discretion,
may approach and negotiate with a restricted  number of potential  purchasers to
effect such sale or  restrict  such sale to a purchaser  or  purchaser  who will
represent and agree that such  purchaser or purchasers are purchasing for his or
their own account,  for investment only, and not with a view of the distribution
or sale of such Collateral or any part thereof. Any such sale shall be deemed to
be a sale made in a  commercially  reasonable  manner  within the meaning of the
Uniform  Commercial  Code of the State of New Jersey and Pledgor hereby consents
and agrees that Secured  Party shall incur no  responsibility  or liability  for
selling all or any part of the  Collateral at a price which is not  unreasonably
low,  notwithstanding  the possibility  that a higher price might be realized if

direct any  prospective  purchaser of any or all of the Collateral to Pledgor to
ascertain all information  concerning the status of Borrower.  Securing  Party's

Pledgor and to any other person with a security  interest in the  Collateral  in
accordance  with the Uniform  Commercial  Code of New Jersey,  or any applicable
successor statute. Such acceptance shall discharge the obligation of Pledgor and
the Corporation with respect to the Indebtedness,  provided that neither Pledgor
nor any other  person  with a security  interest  in the  Collateral  objects in
writing to such a proposal within twenty one (21) calendar days after receipt of
such notice.

     The  proceeds of any sale,  lease or other  disposition  of the  Collateral
shall be applied in the manner and priority set forth in the Uniform  Commercial
Code of New Jersey, or any applicable successor statute.

     7.  Pledgor unconditionally  agrees upon demand to pay to the Secured Party
the amount of any and all reasonable and necessary out-of-pocket costs, expenses
and disbursements, including fees and expenses of its counsel, which the Secured
Party may incur in connection  with (i) the  administration  of this  Agreement,
(ii) the custody,  preservation, use or operation of, or the sale of, collection
from,  or  other  realization  upon,  the  Collateral,  (iii)  the  exercise  or
enforcement  of any of the rights of the  Secured  Party  hereunder  or (iv) the
failure by Pledgor to perform or observe any of the provisions  hereof.  Pledgor
unconditionally  agrees to indemnify  the Secured Party from and against any and
all  claims,  losses  and  liabilities  arising  out of or  resulting  from this
Agreement (including  enforcement of this Agreement),  except claims,  losses or
liabilities  resulting  from the gross  negligence or willful  misconduct of the
Secured Party.

         (a) Proceed against any person;

         (b) Proceed against or exhaust any collateral; or

         (c) Pursue any other remedy in Secured Party's power.

without affecting its liability  hereunder or on the Indebtedness,  from time to
time to:

         (d) Amend  or  modify  the  terms  of  the  Note or the  Guaranty  with
Pledgor's  consent,  including,  but not  limited  to,  any  such  amendment  or
modification which affects the Indebtedness.

manner of sale thereof as Secured Party in its discretion may determine.

     9.  In the event that any additional shares of capital  stock  of  Borrower
are issued to or acquired  by Pledgor  during the term of this  Agreement,  such
additional  shares shall be  considered  additional  Collateral  subject to this
Agreement,  and Pledgor shall immediately deliver stock certificates  evidencing
such  additional  shares of  capital  stock and duly  executed  stock  powers to
Secured Party.

     10. Neither the acceptance of any partial or delinquent  payment by Secured
Party nor Secured  Party's  failure to exercise any of its rights or remedies on
default by Pledgor  shall be a waiver of the  default,  a  modification  of this
Agreement  or Pledgor's  obligations  under this  Agreement,  or a waiver of any
subsequent default by Pledgor.

with,  violate,  result in a breach of, or constitute a default under any of the
terms,  conditions,  or provisions of the articles of incorporation,  bylaws, or
company  agreement  of it or any of its  wholly  owned  subsidiaries  if it is a

or any of its wholly owned  subsidiaries is a party or by which it or any of its
wholly  owned  subsidiaries  is or may be bound or to which any of its  material
properties or assets is subject, (iii) will conflict with, violate,  result in a

           2.3    It is not in violation of any applicable law, or of any order,
writ,  injunction or decree of any court or any governmental  authority.  It has
all the licenses,  permits, consents,  approvals and rights necessary to operate
its business.

           2.4    In deciding to enter into this Agreement, it has not relied on
any statements,  representations,  promises or undertaking or inducements except
as set forth in this Agreement.

           2.5    To the best of its knowledge (said  knowledge  to include  the
knowledge of its agents and  employees)  if Rare and the Lender  consummate  the
transaction  evidenced by the letter of intent (the "Letter") attached hereto as
Exhibit "B" (the "Transaction"):

                                       2
<PAGE>

                  (a)    The creditors of Borrower shall  forgive  approximately
$570,000 in debt, so that at the closing of the Transaction,  the Borrower shall
not have more than $300,000 in outstanding indebtedness; and

                  (b)    Network Consulting Services, Inc. shall continue to pay
on all  equipment  leases  outstanding  as of the  date  of this  Agreement  for
equipment used by Borrower in its business (the "Equipment") throughout the term
of said leases and, at the end of said leases, assuming Borrower has paid either
the $1 or FMV end of lease  payment,  shall  ensure that title to the  Equipment
passes to the Borrower.

           2.6    As of April 19, 2000, Rare and Cash Back have not individually
or  jointly  executed  promissory  notes or  similar  instruments  resulting  in
outstanding indebtedness in excess of $870,000.

                                   ARTICLE III

                                  BREAK UP FEE

           3.1    In consideration of Lender's willingness to make  the  Loan to
Borrower and Lender's  willingness to forego interest on principal amount of the
Loan (other than default interest) and in full recognition that Lender would not
make the Loan to Borrower  without the  agreement  contained in this  paragraph,
Rare and Cash Back agree that if Rare does not consummate the  Transaction  with
Lender  on the terms set forth in the  Letter  (as the same may be  modified  as
mutually agreed by Rare and Lender) after Lender has completed its due diligence
on  the   Transaction   and  received   board  approval  for  a  transaction  on
substantially  the terms set forth in the  Letter  within 3 months of said board
approval,  then (to  compensate  Lender for the loss of a benefit of the bargain
(and not as a penalty))  Rare and Cash Back shall  immediately  upon demand from
Lender  jointly  and  severally  pay to  Lender  a sum of  TWO  MILLION  DOLLARS
($2,000,000) in cash or cash equivalent (the "Fee").  The parties agree, in this
regard,  that the Fee is reasonable and the damages  associated  with failure to
consummate the Transaction are difficult to estimate.

                                   ARTICLE IV

                                  MISCELLANEOUS

           4.1    The parties shall, at their own costs and expense and  without
further   consideration,   execute  and  deliver  such  further   documents  and

                                       3
<PAGE>

instruments  and shall take such other actions as may be reasonably  required or
appropriate to carry out the intent and purposes of this Agreement.

           4.2    This  Agreement shall be in all respects governed by  the laws
of the State of New Jersey in the United States of America.

           4.3    By  signing  this  agreement,  the  parties  hereto  agree and
acknowledge  that they have read this  Agreement,  understand it, and sign it of
their own free will.

           4.4    All notices, consents, waivers, and other communications under
this  Agreement  must be in  writing  and will be deemed to have been duly given
when (a) delivered by hand (with written  confirmation of receipt),  (b) sent by
telecopier  (with  written  confirmation  of receipt),  provided  that a copy is
mailed by registered mail, return receipt requested, or (c) when received by the
addressee, if sent by an overnight delivery service.

           4.5    The  captions  or  headings  of  the  paragraphs   or    other
subdivision hereof are inserted only as a matter of convenience or for reference
and shall have no effect on the meaning of the provisions hereof.

           4.6    The  invalidity  or  unenforceability  of  any  term  of  this
Agreement shall not affect the validity or  enforeceability of this Agreement or
any of its other  terms;  in the event that any court or  arbitrator  determines
that any provision of this  Agreement is invalid or  unenforceable,  as the case
may be,  then,  and in either such event,  neither  the  enforceability  nor the
validity of said paragraph or section as a whole shall be affected.  Rather, the
scope of said  paragraph or section  shall be revised by the court or arbitrator
as little as possible to make the paragraph or section enforceable. If the court
or arbitrator  will not revise said  paragraph or section,  then this  Agreement
shall be  construed  as though the  invalid or  unenforceable  term(s)  were not
included herein.

           4.7    The recitals to this Agreement  shall be deemed a part of this
Agreement.

           4.8    No rule of construction requiring interpretation  against  the
drafting party shall apply to the interpretation of this Agreement.

           4.9    Unless otherwise specified,   all  money  references  in  this
Agreement and all Exhibits thereto are in United States currency.

           4.10   Time is of the essence of this Agreement.

Mr. Thomas J. Vrabel
President
Rare Telephony, Inc. (formerly known as Washoe Technology Corp.)
657 Main Avenue, Suite 301
P.O. Box 9101
Passaic, NJ  07055-9101

Dear Tom:

On behalf of VDC Communications, Inc. ("VDC"), I hereby propose that VDC acquire
Rare Telephony,  Inc. ("RTI") including Cash Back Rebates LD.com, Inc., Free dot
Calling.com,   Inc.  and  its  other   subsidiaries/affiliates  in  a  tax  free
share-for-share acquisition, whereby upon execution of the transaction, VDC will
compensate  RTI's  shareholders  with a total of 1,632,653 VDC common shares for
one hundred percent ownership of RTI, its subsidiaries and affiliates.

Additional terms of the transaction follow:

RTI's shareholders would retain ownership of their VDC shares for at least three
full years  following the closing (i.e.,  they would be subject to a contractual
lock-up).  All RTI  executives  who VDC  chooses to do so would sign  employment
agreements,  which would contain non-compete agreements, and remain with RTI for
at least three full years,  receiving the same salary and  compensation  package
currently paid to them by RTI,  unless VDC should decide in its sole  discretion
to  increase  their  salaries.  To  the  extent  said  executives  breach  their
employment  agreements or fail to serve as employees for three years, they would
forfeit a portion  of their  shares on a sliding  scale  basis as  follows:  50%
during the first one year period following the closing,  33.3% during the second
one year  period  following  the  closing,  20% during the third one year period
following the closing.

The  shares  will  vest and can be sold by their  owner in  accordance  with the
following  schedule:  one third after one full year  following  the closing,  an
additional one third after two full years  following the closing,  an additional
one third after three full years  following the closing.  For  executives  whose

<PAGE>
Mr. Thomas J. Vrabel

Page 2

employment has terminated or who have violated their employment  agreement prior
to the end of the  three  year  period,  the  above  vesting  and  right to sell
schedule  will apply to their  unforfeited  shares  considered  as if they never
owned the forfeited shares. Other RTI employees and significant employees of its
subsidiaries and affiliates that VDC chooses not to employ will sign non-compete
agreements  lasting for at least one year. Peter Salzano  ("P.S."),  currently a
consultant  to RTI,  would  continue to function in that  capacity  for at least
three full years,  receiving the same  compensation  package paid him to date by
RTI. P.S. would sign a non-compete  agreement that would last for at least three
years. In addition,  he would provide VDC with an exclusive  irrevocable license
to utilize his patent pending  technology  which Free dot  Calling.com  plans to
employ in its business.  In return, VDC would pay P.S. $100,000 upon VDC, RTI or
any other VDC  affiliates or  subsidiaries  obtaining two hundred fifty thousand
(250,000) customers through the employment of the patent pending technology, and
if at any time thereafter  through the use of this technology the above entities
have in excess of five  hundred  thousand  (500,000)  then  current  and  active
customers,  VDC would pay to P.S.  25(cent) for each paid customer bill relating
to a particular  month if the average paid customer bill exceeds $25.00 for that
month,  20(cent) for each paid customer  bill relating to a particular  month if
the average paid  customer bill is $20.00 or more for that month but is not more
than $25.00, 15(cent) for each paid customer bill relating to a particular month
if the average paid customer  bill is $15.00 or more for that month,  but is not
more than $20,  10(cent) for each paid  customer  bill  relating to a particular
month if the average paid customer bill is $10.00 or more for that month, but is
not more  than  $15.00,  5(cent)  per bill if the  average  paid  customer  bill
relating to a particular  month is $5.00 or more for that month, but is not more
than  $10.00,  and zero if the average  customer  bill  relating to a particular
month is less than $5.00 for that month.  These  payments would be calculated at
the end of each  calendar  month and paid within 15 days  thereafter,  either in
cash or VDC common stock,  whichever P.S. chooses at the time,  provided however
P.S. will be entitled to no more than one stock  distribution every 6 months. If
the above  mentioned  pending patent is denied by the U.S.  government's  patent
office, the terms herein will remain unaltered.

RTI, its affiliates and subsidiaries, will reduce their existing debt to a total
of no more than  $300,000,  $200,000 of which shall bear an interest rate of 15%
and  $100,000 of which  shall bear an interest  rate of 8%. The term of the debt
will be three  years.  Should  VDC or RTI chose to repay  the debt  prior to the
existing payment  schedule,  they will have the right to do so without incurring
any prepayment penalty.

Once VDC has completed the  acquisition of RTI, it is  anticipated  that VDC may
need  to  fund  RTI up to  $200,000  per  month  for up to  five  months  as RTI
establishes its customer base. In the first two months of this period, RTI could
need modestly more than  $200,000,  while in the latter three months,  it should
require substantially less than $200,000. In addition,  within 60 days following
the closing,  RTI will hire a web site  developer to build a robust web site for
Free dot  Calling.com  to build a web site  capable of handling up to  1,000,000
inquiries per month.  VDC will provide up to $250,000 to fund this  undertaking.
If and when this undertaking has seven hundred and fifty thousand  ($750,000) or
more paying  customers,  VDC will invest an  additional  $250,000 to improve the
capability of the business'  web site and other  equipment to handle  additional
customers so long as the business has generated reasonable profitability.

Mr. Thomas J. Vrabel

VDC must complete its due diligence of RTI by Wednesday, April 19, 2000. At that
point, if VDC decides the investigation has produced  satisfactory  results, the
parties will seek to complete

the necessary  documentation  and close the  transaction as soon as possible and
RTI may request and VDC shall provide a bridge loan of up to $200,000 with an 8%
interest rate. This loan will be fully collateralized and personally  guaranteed
by the executives of RTI, its affiliates and  subsidiaries and repaid within six
months should the parties fail to close the  transaction.  If the transaction is
completed,  this funding  will  constitute  the first  payment of the first five
months funding discussed in the prior paragraph.

This offer is conditional upon VDC's completing a due diligence investigation of
RTI resulting in satisfactory findings in VDC's sole discretion, the approval of
VDC's Board of Directors,  and the execution of formal documents satisfactory to
VDC's counsel.

To compensate VDC for the substantial  expenditures of time, effort, and expense
to be undertaken by VDC in connection with its due diligence,  RTI, on behalf of
itself and its  officers,  directors  and  affiliates  agrees  that it shall not
between the date of this letter and the conclusion of VDC's due diligence, enter
into or conduct any discussions with any other prospective purchaser relating to
the stock or assets that are the subject of this letter.

Finally, RTI, on behalf of its officers,  directors,  and affiliates,  agrees to
keep the terms of this letter and all discussions to date strictly confidential.

The terms of this letter supersede all prior letters, discussions,  arrangements
and understandings relating to the subject matter hereof.

If you are in  agreement  to these  terms,  please so signify by  affixing  your
signature where indicated below.

                                                  Very truly yours,
                                                  /s/ Frederick A. Moran

                      execution  or  otherwise,  and such seizure or levy is not
                      released within thirty (30) calendar days thereafter; or
                  (c) Maker executes a general assignment for the benefit of its
                      creditors,  convenes any meeting of its creditors, becomes
                      insolvent,  admits in writings its insolvency or inability
                      to pay its debts,  or is unable to pay or is generally not
                      paying its debts as they become due; or
                  (d) A receiver,  trustee,  custodian  or agent is appointed to
                      take  possession  of  all or any  substantial  portion  of
                      Maker's assets; or
                  (e) Any case or proceeding is  voluntarily  commenced by Maker
                      under any provision of the federal  Bankruptcy Code or any
                      other   federal   or  state   law   relating   to   debtor
                      rehabilitation,  insolvency,  bankruptcy,  liquidation  or
                      reorganization,   or  any  such  case  or   proceeding  is
                      involuntarily  commenced  against  Maker and not dismissed
                      within thirty (30) calendar days thereafter; or
                  (f) Any representation made by Maker in this Note or in any of
                      the other  documents  delivered in  connection  therewith,
                      shall  have  been  untrue  or  incorrect  in any  material
                      respect when made.

         9.   Default Rate. In the event that Maker fails to pay the Outstanding
              -------------
              Principal Balance and all accrued interest in full on the Maturity
              Date  or the  Accelerated  Maturity  Date,  the  amount  past  due
              (including any acceleration of the Outstanding Principal Balance),
              and unpaid  shall  bear  interest  at an annual  rate equal to the
              lesser of (i) fifteen  percent  (15%),  or (ii) the maximum amount
              permitted by law (the "Default  Rate"),  computed from the date on
              which said amount was due and payable until paid.  The charging or
              collecting  of interest at the Default Rate shall not limit any of
              Holder's other rights or remedies under this Note.

         10.  Governing Law. Maker, and each endorser and cosigner of this Note,
              --------------
              acknowledges  and agrees that this Note is made and is intended to
              be  paid  and  performed  in the  State  of  New  Jersey  and  the

                                       2
<PAGE>

              provisions hereof will be construed in accordance with the laws of
              the State of New Jersey and,  to the extent  that  federal law may
              preempt the  applicability of state laws,  federal law. Maker, and
              each  endorser and  cosigner of this Note further  agree that upon
              the  occurrence of an Event of Default,  this Note may be enforced
              in any court of competent jurisdiction in the State of New Jersey,
              and they do  hereby  submit  to the  jurisdiction  of such  courts
              regardless of their residence.

         11.  Remedies  Cumulative:  Waiver.  The remedies of Holder as provided
              ------------------------------
              herein shall  be  cumulative  and  concurrent,  and may be pursued
              singularly,  successively  or together,  in the sole discretion of
              Holder,  and may  be exercised as often as occasion therefor shall
              arise.  No act of  omission  or  commission  of Holder,  including
              specifically  any  failure  to   exercise  any  right,  remedy  or
              recourse,  shall be deemed to  be a waiver or release of the same;
              such  waiver or release  to  be  affected  only  through a written
              document   executed  by   Holder  and  then  only  to  the  extent
              specifically recited  therein.  Without limiting the generality of
              the preceding sentence,  acceptance by  Holder of any payment with
              knowledge of the occurrence of an Event  of Default by Maker shall
              not be deemed a waiver of such Event of  Default,  and  acceptance
              by Holder of any  payment in an amount  less  than the amount then
              due  hereunder  shall be an  acceptance on  account only and shall
              not in any way  affect  the  existence  of  an  Event  of  Default
              hereunder.  A waiver or release  with  reference to any  one event
              shall not be construed as continuing, as a bar to, or as a  waiver
              or release of, any subsequent  right,  remedy or recourse as  to a
              subsequent event.

         12.  No Usury  Intended.  All  agreements between  Maker and Holder are
              -------------------
              expressly  limited so  that in no contingency or event whatsoever,
              whether by reason of:  error of fact or law;  payment,  prepayment
              or advancement of the  proceeds  hereof;  acceleration of maturity
              of the Outstanding  Principal   Balance,  or otherwise,  shall the
              amount  paid or agreed to be paid  to Holder  hereof  for the use,
              forbearance  or retention of the  money to be advanced  hereunder,
              including any charges  collected  or made in  connection  with the
              indebtedness  evidenced  by  this  Note  which may be  treated  as
              interest under  applicable  law,  if any, exceed the maximum legal
              limit  (if any such  limit  is  applicable)  under  United  States
              federal law or state law (to the extent  not  preempted by federal
              law, if any), now or hereafter  governing  the interest payable in
              connection  with  such  agreements.   If,  from any  circumstances
              whatsoever,  fulfillment  of  any  provision  hereof  at the  time
              performance  of  such   provision   shall  be  due  shall  involve
              transcending  the limit of  validity  (if any)  prescribed  by law
              which a court  of  competent   jurisdiction  may  deem  applicable
              hereto,  then ipso facto, the  obligation to be fulfilled shall be
              reduced  to  the  limit  of  such   validity,   and  if  from  any
              circumstances,  Holder  shall ever  receive  as interest an amount
              which would exceed the maximum  legal  limit (if any such limit is
              applicable),  such amount which  would be excessive interest shall
              be applied to the reduction of the  Outstanding  Principal Balance
              due  hereunder  and  not  to  the   payment  of  interest  or,  if
              necessary,  rebated to Maker.  This provision shall control  every
              other provision of all agreements between Maker and Holder.

              Note is obtained for business or commercial  purposes and that the

         15.  Miscellaneous Provisions.
              -------------------------

              (a) Maker,  and each endorser and cosigner of this Note  expressly
                  grants to Holder  the right to  release or to agree not to sue
                  any other person, or to suspend the right to enforce this Note
                  against  such  other  person or to  otherwise  discharge  such
                  person;  and Maker, and each endorser and cosigner agrees that
                  the  exercise  of such rights by Holder will have no effect on
                  this  liability of any other person,  primarily or secondarily
                  liable  hereunder.  Maker,  and each  endorser and cosigner of
                  this Note  waives,  to the fullest  extent  permitted  by law,
                  demand for payment,  presentment for payment,  protest, notice
                  of protest, notice of dishonor,  notice of nonpayment,  notice
                  of acceleration of maturity, diligence in taking any action to
                  collect sums owing hereunder, any duty or obligation of Holder
                  to effect,  protect,  perfect,  retain or enforce any security
                  for  the  payment  of  this  Note or to  proceed  against  any
                  collateral before otherwise enforcing this Note, and the right
                  to plead as a defense to the  payment  hereof  any  statute of
                  limitations.

              (b) This Note and each payment of principal and interest hereunder
                  shall be paid when due without deduction or setoff of any kind
                  or nature whatsoever.

              (c) Maker  agrees to  reimburse  Holder for all costs,  including,
                  without limitation,  reasonable  attorneys' fees (including an
                  allocable  portion of  in-house  counsel  fees),  incurred  to
                  collect  this  Note  if  this  Note  is  not  paid  when  due,
                  including,  but not limited to,  attorneys' fees (including an
                  allocable  portion  of  in-house  counsel  fees)  incurred  in
                  connection  with any bankruptcy  proceedings  instituted by or
                  against Maker (including relief from stay litigation).

              (d) If any  provision  hereof is for any reason and to any extent,
                  invalid or  unenforceable,  then neither the  remainder of the
                  document  in  which  such  provision  is  contained,  nor  the
                  application  of the  provision to other  persons,  entities or
                  circumstances shall be affected thereby,  but instead shall be
                  enforceable to the maximum extent permitted by law.

              (e) This Note shall be a joint and  several  obligation  of Maker,
                  and of all endorsers and cosigners hereof and shall be binding
                  upon   them   and    their    respective    heirs,    personal
                  representatives, successors and assigns.

              (f) This Note may not be modified or amended orally, but only by a
                  modification  or  amendment  in  writing  signed by Holder and
                  Maker.

              (g) When the context and  construction so require,  all words used
                  in the  singular  herein  shall be deemed to have been used in
                  the plural and the  masculine  shall  include the feminine and
                  neuter and vice versa.  The word "person" as used herein shall
                  include   any   individual,    company,   firm,   association,
                  partnership,  corporation,  trust or other legal entity of any
                  kind whatsoever.

              (h) The headings of the  paragraphs  and sections of this Note are
                  for  convenience or reference only, are not to be considered a
                  part hereof and shall not limit or otherwise affect any of the
                  terms hereof.

              (i) In the event that at any time any  payment  received by Holder
                  hereunder  shall  be  deemed  by  final  order  of a court  of
                  competent  jurisdiction to have been a voidable  preference or
                  fraudulent  conveyance under the bankruptcy or insolvency laws
                  of the United States,  or shall  otherwise be deemed to be due
                  to any party other than Holder,  then, in any such event,  the
                  obligation to make such payment shall survive any cancellation
                  of this Note and/or  return  thereof to Maker and shall not be
                  discharged  or satisfied by any prior payment  thereof  and/or
                  cancellation  of this  Note,  but  shall  remain  a valid  and
                  binding  obligation  enforceable in accordance  with the terms
                  and  provisions  hereof,  and the amount of such payment shall
                  bear  interest at the Default Rate from the date of such final
                  order until repaid hereunder.


         IN WITNESS  WHEREOF Maker has executed this  Promissory  Note as of the
day and year first above written.

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

     THIS GUARANTY AGREEMENT ("Guaranty Agreement")  is made  and  entered  into
this 4th day of May, 2000 by Network  Consulting Group, Inc.  ("Guarantor"),  in
favor of VDC Communications, Inc. ("Lender").

                                   WITNESSETH:
                                   -----------

     WHEREAS,   concurrently  herewith,  Rare  Telephony,   Inc.  (f/k/a  Washoe
Technology  Corporation) and Cash Back Rebates LD.com,  Inc. Nevada and Delaware
corporations respectively ("Borrower"),  have executed a certain Promissory Note
in favor of Lender  in the  stated  principal  amount  of One  Hundred  Thousand
Dollars ($100,000) (the "Note"); and

     WHEREAS,  to  induce  Lender  to lend  the  One  Hundred  Thousand  Dollars
($100,000) to Borrower, Guarantor has agreed to guarantee the Note;

     NOW,  THEREFORE,  in  consideration  of the premises and for other good and
valuable  consideration,  the  receipt  and  sufficiency  of  which  are  hereby
acknowledged, the parties hereby covenant and agree as follows:

     1.  Guarantor irrevocably and  unconditionally,  fully guarantees to Lender
the full and  prompt  payment  of the  indebtedness  evidenced  by the Note (the
"Indebtedness") at the times and according to the terms expressed.

     Guarantor  agrees that if all or any part of the  Indebtedness  is not paid
according to the tenor thereof,  Guarantor shall, upon demand of Lender, pay the
Indebtedness  in like manner as if the  Indebtedness  constituted the direct and
primary  obligation of Guarantor as provided for herein.  Guarantor's  liability
hereunder shall be IN THE FULL AMOUNT of the Indebtedness.

     2.  This Guaranty Agreement is  irrevocable  and shall remain in full force
and effect  continuously from the date hereof to and until the date on which the
Indebtedness  is  paid  in  full,   whereupon  this  Guaranty   Agreement  shall
automatically terminate ("Termination Date").

     3.  Guarantor grants to Lender, in Lender's  sole and  absolute  discretion
and without  notice to Guarantor,  the power and authority to deal in any lawful
manner  with the  Indebtedness  and,  without  limiting  the  generality  of the
foregoing, the power and authority from time to time:

                                       1
<PAGE>

         (a) To change, amend or modify the Note or any other documents relating
thereto in a non-material way (collectively, the "Loan Documents");

         (b) To discharge or release any person liable under the Loan Documents;

         (c) To take and  hold  security  for the  payment  of the  Indebtedness
and/or  the  performance  of the other  obligations  guaranteed  herein,  and to
exchange, enforce, subordinate, waive or release any such security;

         (d) To foreclose any security for the  Indebtedness,  and to direct the
order or manner of sale of any such  security  as  Lender in  Lender's  sole and
absolute discretion may determine;

         (e) To grant any  extensions  of time,  renewals or other  indulgences,
forbearance,  waivers or releases to Borrower or any other  person  liable under
the Loan Documents.

         (f) To accept  or  make  compositions  or other  alignments  or file or
refrain  from filing a claim in any  bankruptcy  proceedings  of Borrower or any
other person liable under the Loan Documents;

         (g) To credit  payments on the  Indebtedness in such manner and in such
order of  priority  as  Lender  may  determine  in  lender's  sole and  absolute
discretion; and

         (h) To otherwise  deal with  Borrower or any other  guarantor or person
related to the  Indebtedness or any security as Lender may determine in Lender's
sole and absolute discretion.

     Without limiting the generality of the foregoing,  Guarantor WAIVES any and
all rights,  benefits and defenses  under law which may provide that a surety is
exonerated if a creditor, without the consent of the surety, alters the original
obligation  of the  principal  in any  respect,  or if the  creditor  in any way
imperils or suspends the creditor's rights against the principal.

     The liability of Guarantor shall not be terminated,  affected,  impaired or
reduced in any way by any action taken by Lender under the foregoing  provisions
or any other provision  hereof or by any delay,  failure or refusal of Lender to
exercise  any right or remedy  Lender  may have  against  Borrower  or any other
person,  including other  guarantors,  if any, liable for all or any part of the
Indebtedness hereby guaranteed.

     4.  If at any time all or any  part of any  payment  made by  Guarantor  or
received  by  Lender  from  Guarantor  under or with  respect  to this  Guaranty
Agreement  is avoided or  recovered  directly  or  indirectly  from  Lender as a

                                       2
<PAGE>

preference,  fraudulent  transfer,  or otherwise,  then Guarantor's  obligations
hereunder shall, to the extent of the payment avoided or recovered, be deemed to
have  continued in  existence,  notwithstanding  such  previous  payment made by
Guarantor or receipt of payment by Lender, and Guarantor's obligations hereunder
shall continue to be effective or be reinstated,  as the case may be, as to such
payment,  all as though such previous  payment by Guarantor had never been made,
irrespective of the payment in full of the Indebtedness.

     5.  To the fullest  extent permitted by law,  Guarantor  hereby  WAIVES the
following rights, defenses and benefits:

         a. The defense of the statute of limitations in any action hereunder or
in any action for the collection of the  Indebtedness  or the performance of any
other obligation hereby guaranteed;

         b. Any  defense  that may arise by reason  of the  incapacity,  lack of
authority,  death or disability of any other person or persons or the failure of
Lender  to file or  enforce  a claim  against  the  estate  (in  administration,
bankruptcy or any other proceeding) of any other person or persons

         c. Except as  otherwise  provided  herein,  diligence  and all demands,
presentment for payment,  notice of nonpayment,  protest,  notice of protest and
all other notices of any kind, including, without limiting the generality of the
foregoing,  notice  of the  existence,  creation  or  incurring  of  any  new or
additional  obligation  or of any action or  nonaction  on the part of Borrower,
Lender,  any  endorser or creditor of Borrower or of Guarantor or on the part of
any other person  whomsoever  under this or any other  instrument  in connection
with  any  Indebtedness  or  evidence  of  Indebtedness  held  by  Lender  or in
connection with the Indebtedness hereby guaranteed;

         d. Any duty or obligation on Lender's part to perfect,  protect, retain
or enforce any security for the payment of the  Indebtedness  or the performance
of any of the other obligations guaranteed herein;

         e. Any duty on the part of Lender to  disclose to  Guarantor  any facts
Lender may now or hereafter  know about  Borrower,  regardless of whether Lender
has reason to believe  that any such facts  materially  increase the risk beyond
that which Guarantor  intends to assume or has reason to believe that such facts
are unknown to Guarantor or has a reasonable  opportunity  to  communicate  such
facts to  Guarantor,  it being  understood  and agreed that  Guarantor  is fully
responsible  for  being and  keeping  informed  of the  financial  condition  of
Borrower and of any and all circumstances bearing on the risk that liability may
be incurred by Guarantor hereunder; and

                                       3
<PAGE>

         f. Any and all rights,  benefits  and defenses  under law  available to
guarantors or sureties, including without limitations, any such rights, benefits
or defenses which would otherwise  require Lender to proceed against Borrower or
any other person,  or to proceed  against or exhaust any security held by Lender
at any time,  or to first apply any security of Borrower to the discharge of the
Indebtedness,  or to pursue any other remedy in Lender's power before proceeding
against Guarantor hereunder.

     6.  Guarantor agrees  that  Guarantor  shall have no right of  subrogation,
reimbursement, exoneration, contribution, indemnity, or similar right as against
Borrower  which would  result in  Guarantor  being deemed a creditor of Borrower
under the Federal Bankruptcy Code or any other law or for any other purpose; and
Guarantor  further  WAIVES any and all rights,  benefits and defenses under law,
which may provide that a surety is entitled to the benefit of every security for
the performance of the principal obligation held by the creditor.

     7.  With or without notice to  Guarantor  and without  affecting in any way
Guarantor's  obligation or liability  hereunder for payment of the Indebtedness,
Lender, in Lender's sole and absolute  discretion,  at any time and from time to
time, and in such manner and upon such terms as Lender deems fit, may:

     a.  Apply any or all payments or recoveries from Borrower or from all other
guarantors  or  endorsers  under  any  other  instrument  or  realized  from any
security,  in such  manner  and order of  priority  as lender may  determine  in
Lender's  sole and  absolute  discretion,  to any  Indebtedness  of  Borrower to
Lender,  whether or not such  Indebtedness is guaranteed  hereby or is otherwise
secured or is due at the time of such application; or

     b.  Refund to Borrower any payment received by Lender upon the Indebtedness
hereby guaranteed.

     8.  All rights, powers and remedies of Lender hereunder shall be cumulative
and not alternative and such rights, powers and remedies shall be in addition to
all  rights,  powers  and  remedies  given to lender  under  the Loan  Documents
(including any other guarantees of the Indebtedness) or otherwise by law.

     9.  The liability of Guarantor  under this Guaranty  Agreement  shall be an
absolute,  direct,  immediate and unconditional  guarantee of payment and not of
collection.  The  Indebtedness  of  Guarantor  hereunder is  independent  of the
Indebtedness  of  Borrower  and  is  not  conditioned  on  contingent  upon  the
genuineness,   validity,  regularity  or  enforceability  of  any  of  the  Loan
Documents.  In the event of any default hereunder,  a separate action or actions
may be brought and  prosecuted  against  Guarantor,  whether or not  Borrower is
joined  therein or a separate  action or actions are brought  against  Borrower.

                                       4
<PAGE>

Lender may enforce  Lender's rights under the Guaranty  Agreement  without first
exercising  any other  remedy or right that Lender may have or seeking to obtain
payment or  performance  from  Borrower,  any other person  (including any other
guarantor)  or from any  collateral  which  Lender may hold as security  for the
Indebtedness.  Lender  may  maintain  successive  actions  for  other  defaults.
Lender's  rights  hereunder  shall not be  exhausted  by the  exercise of any of
Lender's rights or remedies or by any such action or by any number of successive
actions.  Guarantor  WAIVES any and all rights,  benefits and defenses under law
which may  generally  provide  that a  guarantor  or surety is not liable if for
certain  reasons there is no liability  upon the part of the principal or if the
principal  ceases to  become  liable or which  may  generally  provide  that the
Indebtedness  of a guarantor  or surety  must not be larger nor more  burdensome
than that of the principal.

     10. Notwithstanding  the fact that Borrower may be a corporation,  a  joint
venture or a  partnership,  Lender is not to be concerned to see or inquire into
the powers of Borrower,  its  directors,  officers,  joint  ventures,  partners,
associates  or other  agents  acting or  purporting  to act on its  behalf,  and
Guarantor  expressly  waives any  defense to the  enforcement  of this  Guaranty
Agreement to the effect that the transaction  between  Borrower and Lender is in
excess  of the  powers  of the  Borrower,  or  shall  be in any  way  irregular,
defective or informal.  Guarantor's liability hereunder shall not be affected by
changes in the name of the entity or the constituent members of the entity which
constitutes Borrower.

     11. It is expressly  understood that the obligations of Guarantor hereunder
are an additional and cumulative benefit given to Lender for Lender's security.

     12. No action based on this Guaranty  Agreement  shall be instituted  until
written demand for payment or performance,  as  appropriate,  has been made upon
Guarantor (a) upon delivery of such demand in person to Guarantor, or (b) on the
next business day following  deposit of an envelope  containing such demand with
an overnight  courier  service (such as United  Parcel  Service) for delivery to
Guarantor at the address set forth next to Guarantor's  signature hereon, or (c)
on the second  business day  following  deposit of an envelope  containing  such
demand  in  the  United   States  mail,   postage   prepaid,   certified   mail,
return-receipt  requested,  addressed to Guarantor as described above. Guarantor
may change  Guarantor's  address for such notices by giving notice of the change
of address to Lender in the manner provided herein. All payments hereunder shall
be made in lawful  money of the  United  States of  America.  No delay in making
demand on Guarantor for satisfaction of Guarantor's  liabilities hereunder shall
prejudice Lender's right to enforce such satisfaction.

     13. Guarantor  shall pay  to Lender,  upon written  demand,  all reasonable
attorneys'  fees (including an allocable  portion of in-house  counsel fees) and
all costs and other  expenses  which Lender  expends or incurs in enforcing this

                                       5
<PAGE>

Guaranty  Agreement against  Guarantor whether or not suit is filed,  including,
without  limitation,  all  reasonable  attorneys'  fees  (including an allocable
portion of in-house  counsel  fees),  costs and  expenses  incurred by Lender in
connection with any insolvency, bankruptcy, reorganization, arrangement or other
similar proceedings  involving Borrower or Guarantor which in any way affect the
exercise  by Lender of Lender's  rights and  remedies  hereunder.  Until paid to
Lender, such attorneys' fees (including an allocable portion of in-house counsel
fees),  costs and expenses  shall bear  interest at the highest rate of interest
allowable by law.

     14. Should  any  one or  more  provisions  of this  Guaranty  Agreement  be
determined to be illegal or  unenforceable,  all other  provisions  nevertheless
shall be effective.

     15. No provision of this  Guaranty  Agreement or right of Lender  hereunder
can  be  waived  nor  shall  Guarantor  be  released  from  any  of  Guarantor's
obligations  hereunder  except by a writing duly  executed by Lender,  or unless
this Guaranty  Agreement  terminates  pursuant to its terms as set forth herein.
This Guaranty Agreement may not be modified, amended, revised, changed or varied
in any way whatsoever  except by the express terms of a writing duly executed by
Lender and Guarantor.

     16. When the context and  construction  so requires,  all words used in the
singular  herein  shall be  deemed  to have  been  used in the  plural,  and the
masculine  shall  include  the  feminine  and neuter,  and vice versa.  The word
"person"  as  used  herein  shall  include  any   individual,   company,   firm,
association,  partnership,  corporation, trust or other legal entity of any kind
whatsoever.  The word  "Borrower"  as used herein  includes  Borrower  acting on
behalf of itself or any estate created by the  commencement  of a case under the
Federal Bankruptcy Code or any other insolvency,  bankruptcy,  reorganization or
liquidation  proceeding,  or by any trustee under the Federal  Bankruptcy  Code,
liquidator,  sequestrator,  and receiver of Borrower and Borrower's  property or
similar  person duly  appointed  pursuant to any laws  generally  governing  any
insolvency,  bankruptcy,  reorganization,   liquidation,  receivership  or  like
proceeding.  If more than one person  has  signed  this  Guaranty  Agreement  as
Guarantor,  it shall be the joint and several  obligation  of each of them.  The
words "Loan  Documents" as used herein  include any  modifications,  extensions,
renewals,  or  replacements  thereof.  All  references to statutes  herein shall
include any modifications, amendments, substitutions or replacements thereof.

     17. In the event that all or any part of the  Indebtedness  is  assigned by
Lender,  this Guaranty  Agreement shall  automatically be assigned  therewith in
whole or in part, as applicable, without the need of any express assignment and,
when so assigned,  Guarantor shall be bound as above to the assignee(s)  without
in any manner  affecting  Guarantor's  liability  hereunder  for any part of the
Indebtedness retained by Lender.

                                       6
<PAGE>

     18. Guarantor  agrees,  within  seven (7) calendar  days after request from
Lender, to deliver to Lender a statement certifying that this Guaranty Agreement
is in full force and effect, and that no defense of offset exists to Guarantor's
obligations under the Guaranty Agreement (or stating any facts to the contrary).

     19. This  Guaranty  Agreement  shall  inure to the benefit of and  bind the
heirs, legal representatives, administrators, executors, successors, and assigns
of Lender and of Guarantor.

     20. Guarantor hereby agrees that:

         a. The execution  and delivery to Lender of this Guaranty  Agreement of
the  accrual  of a claim  hereunder  in favor of Lender  shall be deemed to have
caused an event to occur in the State of New Jersey,  bringing  Guarantor within
the jurisdiction of the state and federal courts in the State of New Jersey, and
Guarantor further hereby agrees to and, as a separate and independent  covenant,
does hereby submit to the  jurisdiction  of the state and federal  courts in the
State of New Jersey; and

         b. This  Guaranty  Agreement is made in the State of New Jersey and the
provisions hereof shall be construed and enforced in accordance with the laws of
the State of New Jersey  (irrespective  of its  conflicts of laws rules) and, to
the extent that federal law may preempt the applicability of state laws, federal
law.

     21. Except as provided in any other written agreement at any time hereafter
in force between Lender and Guarantor,  this Guaranty Agreement shall constitute
the entire agreement of Guarantor with Lender with respect to the subject matter
hereof and no representation, understanding, promise or condition concerning the
subject matter hereof shall be binding upon Lender unless expressed herein.

                           PERSONAL GUARANTY AGREEMENT
                           ---------------------------

     THIS GUARANTY  AGREEMENT  ("Guaranty  Agreement")  is made and entered into
this 4th day of May,  2000 by Peter J.  Salzano  ("Guarantor"),  in favor of VDC
Communications, Inc. ("Lender").

                                   WITNESSETH:
                                   -----------

     WHEREAS,   concurrently  herewith,  Rare  Telephony,   Inc.  (f/k/a  Washoe
Technology  Corporation) and Cash Back Rebates LD.com,  Inc. Nevada and Delaware
corporations respectively ("Borrower"),  have executed a certain Promissory Note
in favor of Lender  in the  stated  principal  amount  of One  Hundred  Thousand
Dollars ($100,000) (the "Note"); and

     WHEREAS,  to  induce  Lender  to lend  the  One  Hundred  Thousand  Dollars
($100,000) to Borrower, Guarantor has agreed to guarantee the Note;

     NOW,  THEREFORE,  in  consideration  of the premises and for other good and
valuable  consideration,  the  receipt  and  sufficiency  of  which  are  hereby
acknowledged, the parties hereby covenant and agree as follows:

     1.  Guarantor irrevocably and  unconditionally,  fully guarantees to Lender
the full and  prompt  payment  of the  indebtedness  evidenced  by the Note (the
"Indebtedness") at the times and according to the terms expressed.

     Guarantor  agrees that if all or any part of the  Indebtedness  is not paid
according to the tenor thereof,  Guarantor shall, upon demand of Lender, pay the
Indebtedness  in like manner as if the  Indebtedness  constituted the direct and
primary  obligation  of Guarantor as provided for herein.  Guarantor's  personal
liability hereunder shall be IN THE FULL AMOUNT of the Indebtedness.

     2.  This Guaranty Agreement is  irrevocable  and shall remain in full force
and effect  continuously from the date hereof to and until the date on which the
Indebtedness  is  paid  in  full,   whereupon  this  Guaranty   Agreement  shall
automatically terminate ("Termination Date").

     3.  Guarantor grants to Lender,  in  Lender's sole  and absolute discretion
and without  notice to Guarantor,  the power and authority to deal in any lawful
manner  with the  Indebtedness  and,  without  limiting  the  generality  of the
foregoing, the power and authority from time to time:

                                       1
<PAGE>

         (a) To change, amend or modify the Note or any other documents relating
thereto in a non-material way (collectively, the "Loan Documents");

         (b) To discharge or release any person liable under the Loan Documents;

         (c) To take and  hold  security  for the  payment  of the  Indebtedness
and/or  the  performance  of the other  obligations  guaranteed  herein,  and to
exchange, enforce, subordinate, waive or release any such security;

         (d) To foreclose any security for the  Indebtedness,  and to direct the
order or manner of sale of any such  security  as  Lender in  Lender's  sole and
absolute discretion may determine;

         (e) To grant any  extensions  of time,  renewals or other  indulgences,
forbearance,  waivers or releases to Borrower or any other  person  liable under
the Loan Documents.

         (f) To  accept  or make  compositions  or other  alignments  or file or
refrain  from filing a claim in any  bankruptcy  proceedings  of Borrower or any
other person liable under the Loan Documents;

         (g) To credit  payments on the  Indebtedness in such manner and in such
order of  priority  as  Lender  may  determine  in  lender's  sole and  absolute
discretion; and

         (h) To otherwise  deal with  Borrower or any other  guarantor or person
related to the  Indebtedness or any security as Lender may determine in Lender's
sole and absolute discretion.

     Without limiting the generality of the foregoing,  Guarantor WAIVES any and
all rights,  benefits and defenses  under law which may provide that a surety is
exonerated if a creditor, without the consent of the surety, alters the original
obligation  of the  principal  in any  respect,  or if the  creditor  in any way
imperils or suspends the creditor's rights against the principal.

     The liability of Guarantor shall not be terminated,  affected,  impaired or
reduced in any way by any action taken by Lender under the foregoing  provisions
or any other provision  hereof or by any delay,  failure or refusal of Lender to
exercise  any right or remedy  Lender  may have  against  Borrower  or any other
person,  including other  guarantors,  if any, liable for all or any part of the
Indebtedness hereby guaranteed.

     4.  If at any time all or any  part of any  payment  made by  Guarantor  or
received  by  Lender  from  Guarantor  under or with  respect  to this  Guaranty
Agreement  is avoided or  recovered  directly  or  indirectly  from  Lender as a
preference,  fraudulent  transfer,  or otherwise,  then Guarantor's  obligations

                                       2
<PAGE>

hereunder shall, to the extent of the payment avoided or recovered, be deemed to
have  continued in  existence,  notwithstanding  such  previous  payment made by
Guarantor or receipt of payment by Lender, and Guarantor's obligations hereunder
shall continue to be effective or be reinstated,  as the case may be, as to such
payment,  all as though such previous  payment by Guarantor had never been made,
irrespective of the payment in full of the Indebtedness.


     5.  To the fullest extent  permitted by law,  Guarantor  hereby  WAIVES the
following rights, defenses and benefits:

         a.  The defense of the statute of limitations in any  action  hereunder
or in any action for the collection of the  Indebtedness  or the  performance of
any other obligation hereby guaranteed;

         b.  Any defense  that may arise by reason  of the  incapacity,  lack of
authority,  death or disability of any other person or persons or the failure of
Lender  to file or  enforce  a claim  against  the  estate  (in  administration,
bankruptcy or any other proceeding) of any other person or persons

         c.  Except as otherwise  provided  herein,  diligence  and all demands,
presentment for payment,  notice of nonpayment,  protest,  notice of protest and
all other notices of any kind, including, without limiting the generality of the
foregoing,  notice  of the  existence,  creation  or  incurring  of  any  new or
additional  obligation  or of any action or  nonaction  on the part of Borrower,
Lender,  any  endorser or creditor of Borrower or of Guarantor or on the part of
any other person  whomsoever  under this or any other  instrument  in connection
with  any  Indebtedness  or  evidence  of  Indebtedness  held  by  Lender  or in
connection with the Indebtedness hereby guaranteed;

         d.  Any duty or obligation on Lender's part to perfect, protect, retain
or enforce any security for the payment of the  Indebtedness  or the performance
of any of the other obligations guaranteed herein;

         e.  Any duty on the part of Lender to disclose to  Guarantor  any facts
Lender may now or hereafter  know about  Borrower,  regardless of whether Lender
has reason to believe  that any such facts  materially  increase the risk beyond
that which Guarantor  intends to assume or has reason to believe that such facts
are unknown to Guarantor or has a reasonable  opportunity  to  communicate  such
facts to  Guarantor,  it being  understood  and agreed that  Guarantor  is fully
responsible  for  being and  keeping  informed  of the  financial  condition  of

                                       3
<PAGE>

Borrower and of any and all circumstances bearing on the risk that liability may
be incurred by Guarantor hereunder; and

         f.  Any and all rights, benefits  and defenses  under law  available to
guarantors or sureties, including without limitations, any such rights, benefits
or defenses which would otherwise  require Lender to proceed against Borrower or
any other person,  or to proceed  against or exhaust any security held by Lender
at any time,  or to first apply any security of Borrower to the discharge of the
Indebtedness,  or to pursue any other remedy in Lender's power before proceeding
against Guarantor hereunder.

     6.  Guarantor  agrees that  Guarantor  shall have no right of  subrogation,
reimbursement, exoneration, contribution, indemnity, or similar right as against
Borrower  which would  result in  Guarantor  being deemed a creditor of Borrower
under the Federal Bankruptcy Code or any other law or for any other purpose; and
Guarantor  further  WAIVES any and all rights,  benefits and defenses under law,
which may provide that a surety is entitled to the benefit of every security for
the performance of the principal obligation held by the creditor.

     7.  With or without notice to  Guarantor  and without  affecting in any way
Guarantor's  obligation or liability  hereunder for payment of the Indebtedness,
Lender, in Lender's sole and absolute  discretion,  at any time and from time to
time, and in such manner and upon such terms as Lender deems fit, may:

     a.  Apply any or all payments or recoveries from Borrower or from all other
guarantors  or  endorsers  under  any  other  instrument  or  realized  from any
security,  in such  manner  and order of  priority  as lender may  determine  in
Lender's  sole and  absolute  discretion,  to any  Indebtedness  of  Borrower to
Lender,  whether or not such  Indebtedness is guaranteed  hereby or is otherwise
secured or is due at the time of such application; or

     b.  Refund to Borrower any payment received by Lender upon the Indebtedness
hereby guaranteed.

     8.  All rights, powers and remedies of Lender hereunder shall be cumulative
and not alternative and such rights, powers and remedies shall be in addition to
all  rights,  powers  and  remedies  given to lender  under  the Loan  Documents
(including any other guarantees of the Indebtedness) or otherwise by law.

     9.  The liability of Guarantor  under this Guaranty  Agreement  shall be an
absolute,  direct,  immediate and unconditional  guarantee of payment and not of
collection.  The  Indebtedness  of  Guarantor  hereunder is  independent  of the
Indebtedness  of  Borrower  and  is  not  conditioned  on  contingent  upon  the
genuineness,   validity,  regularity  or  enforceability  of  any  of  the  Loan
Documents.  In the event of any default hereunder,  a separate action or actions

                                       4
<PAGE>

may be brought and  prosecuted  against  Guarantor,  whether or not  Borrower is
joined  therein or a separate  action or actions are brought  against  Borrower.
Lender may enforce  Lender's rights under the Guaranty  Agreement  without first
exercising  any other  remedy or right that Lender may have or seeking to obtain
payment or  performance  from  Borrower,  any other person  (including any other
guarantor)  or from any  collateral  which  Lender may hold as security  for the
Indebtedness.  Lender  may  maintain  successive  actions  for  other  defaults.
Lender's  rights  hereunder  shall not be  exhausted  by the  exercise of any of
Lender's rights or remedies or by any such action or by any number of successive
actions.  Guarantor  WAIVES any and all rights,  benefits and defenses under law
which may  generally  provide  that a  guarantor  or surety is not liable if for
certain  reasons there is no liability  upon the part of the principal or if the
principal  ceases to  become  liable or which  may  generally  provide  that the
Indebtedness  of a guarantor  or surety  must not be larger nor more  burdensome
than that of the principal.

     10. Notwithstanding  the  fact that Borrower may be a corporation,  a joint
venture or a  partnership,  Lender is not to be concerned to see or inquire into
the powers of Borrower,  its  directors,  officers,  joint  ventures,  partners,
associates  or other  agents  acting or  purporting  to act on its  behalf,  and
Guarantor  expressly  waives any  defense to the  enforcement  of this  Guaranty
Agreement to the effect that the transaction  between  Borrower and Lender is in
excess  of the  powers  of the  Borrower,  or  shall  be in any  way  irregular,
defective or informal.  Guarantor's liability hereunder shall not be affected by
changes in the name of the entity or the constituent members of the entity which
constitutes Borrower.

     11. It is expressly  understood that the obligations of Guarantor hereunder
are an additional and cumulative benefit given to Lender for Lender's security.

     12. No action based on this Guaranty  Agreement  shall be instituted  until
written demand for payment or performance,  as  appropriate,  has been made upon
Guarantor (a) upon delivery of such demand in person to Guarantor, or (b) on the
next business day following  deposit of an envelope  containing such demand with
an overnight  courier  service (such as United  Parcel  Service) for delivery to
Guarantor at the address set forth next to Guarantor's  signature hereon, or (c)
on the second  business day  following  deposit of an envelope  containing  such
demand  in  the  United   States  mail,   postage   prepaid,   certified   mail,
return-receipt  requested,  addressed to Guarantor as described above. Guarantor
may change  Guarantor's  address for such notices by giving notice of the change
of address to Lender in the manner provided herein. All payments hereunder shall
be made in lawful  money of the  United  States of  America.  No delay in making
demand on Guarantor for satisfaction of Guarantor's  liabilities hereunder shall
prejudice Lender's right to enforce such satisfaction.

                                       5

     13.  Guarantor  shall pay to Lender,  upon written  demand,  all reasonable
attorneys'  fees (including an allocable  portion of in-house  counsel fees) and
all costs and other  expenses  which Lender  expends or incurs in enforcing this
Guaranty  Agreement against  Guarantor whether or not suit is filed,  including,
without  limitation,  all  reasonable  attorneys'  fees  (including an allocable
portion of in-house  counsel  fees),  costs and  expenses  incurred by Lender in
connection with any insolvency, bankruptcy, reorganization, arrangement or other
similar proceedings  involving Borrower or Guarantor which in any way affect the
exercise  by Lender of Lender's  rights and  remedies  hereunder.  Until paid to
Lender, such attorneys' fees (including an allocable portion of in-house counsel
fees),  costs and expenses  shall bear  interest at the highest rate of interest
allowable by law.

     14. Should  any  one or more  provisions  of  this  Guaranty  Agreement  be
determined to be illegal or  unenforceable,  all other  provisions  nevertheless
shall be effective.

     15. No provision of this  Guaranty  Agreement or right of Lender  hereunder
can  be  waived  nor  shall  Guarantor  be  released  from  any  of  Guarantor's
obligations  hereunder  except by a writing duly  executed by Lender,  or unless
this Guaranty  Agreement  terminates  pursuant to its terms as set forth herein.
This Guaranty Agreement may not be modified, amended, revised, changed or varied
in any way whatsoever  except by the express terms of a writing duly executed by
Lender and Guarantor.

     16. When the context and  construction  so requires,  all words used in the
singular  herein  shall be  deemed  to have  been  used in the  plural,  and the
masculine  shall  include  the  feminine  and neuter,  and vice versa.  The word
"person"  as  used  herein  shall  include  any   individual,   company,   firm,
association,  partnership,  corporation, trust or other legal entity of any kind
whatsoever.  The word  "Borrower"  as used herein  includes  Borrower  acting on
behalf of itself or any estate created by the  commencement  of a case under the
Federal Bankruptcy Code or any other insolvency,  bankruptcy,  reorganization or
liquidation  proceeding,  or by any trustee under the Federal  Bankruptcy  Code,
liquidator,  sequestrator,  and receiver of Borrower and Borrower's  property or
similar  person duly  appointed  pursuant to any laws  generally  governing  any
insolvency,  bankruptcy,  reorganization,   liquidation,  receivership  or  like
proceeding.  If more than one person  has  signed  this  Guaranty  Agreement  as
Guarantor,  it shall be the joint and several  obligation  of each of them.  The
words "Loan  Documents" as used herein  include any  modifications,  extensions,
renewals,  or  replacements  thereof.  All  references to statutes  herein shall
include any modifications, amendments, substitutions or replacements thereof.

     17. In the event that all or any part of the  Indebtedness  is  assigned by
Lender,  this Guaranty  Agreement shall  automatically be assigned  therewith in
whole or in part, as applicable, without the need of any express assignment and,

                                       6
<PAGE>

when so assigned,  Guarantor shall be bound as above to the assignee(s)  without
in any manner  affecting  Guarantor's  liability  hereunder  for any part of the
Indebtedness retained by Lender.

     18. Guarantor  agrees,  within  seven (7) calendar  days after request from
Lender, to deliver to Lender a statement certifying that this Guaranty Agreement
is in full force and effect, and that no defense of offset exists to Guarantor's
obligations under the Guaranty Agreement (or stating any facts to the contrary).

     19. This  Guaranty  Agreement  shall  inure to the benefit  of and bind the
heirs, legal representatives, administrators, executors, successors, and assigns
of Lender and of Guarantor.

     20. Guarantor hereby agrees that:

         a.  The execution and delivery to Lender of this Guaranty  Agreement of
the  accrual  of a claim  hereunder  in favor of Lender  shall be deemed to have
caused an event to occur in the State of New Jersey,  bringing  Guarantor within
the jurisdiction of the state and federal courts in the State of New Jersey, and
Guarantor further hereby agrees to and, as a separate and independent  covenant,
does hereby submit to the  jurisdiction  of the state and federal  courts in the
State of New Jersey; and

         b.  This Guaranty  Agreement is made in the State of New Jersey and the
provisions hereof shall be construed and enforced in accordance with the laws of
the State of New Jersey  (irrespective  of its  conflicts of laws rules) and, to
the extent that federal law may preempt the applicability of state laws, federal
law.

     21. Except as provided in any other written agreement at any time hereafter
in force between Lender and Guarantor,  this Guaranty Agreement shall constitute
the entire agreement of Guarantor with Lender with respect to the subject matter
hereof and no representation, understanding, promise or condition concerning the
subject matter hereof shall be binding upon Lender unless expressed herein.
