               WORLDPORT COMMUNICATIONS, INC. AND SUBSIDIARIES


             NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                 (Unaudited)


(1)   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      Basis of Presentation
      ---------------------
      WorldPort Communications,  Inc. and its subsidiaries,  ("WorldPort" or the
      "Company"), a Delaware corporation, is a facilities-based network provider
      of enhanced  international and domestic  telecommunication  services.  The
      Company  operates  telecommunications  switches  and an operator  services
      platform in Omaha, Nebraska from which it provides enhanced services, such
      as  global  calling  cards  and  international   prepaid  debit  cards  to
      individuals,  small businesses and large corporate  customers primarily in
      the United States, Western Europe and Latin America.

      The accompanying  condensed  consolidated  financial  statements have been
      prepared  by  the  Company   without  audit  pursuant  to  the  rules  and
      regulations of the Securities and Exchange Commission. Certain information
      and  footnote   disclosures  normally  included  in  financial  statements
      prepared in accordance with generally accepted accounting  principles have
      been  condensed or omitted in this Form 10-QSB  pursuant to such rules and
      regulations;  however, management believes that the disclosures herein are
      adequate to make the information  presented not misleading.  The financial
      statements  and notes thereto  included in this Form 10-QSB should be read
      in conjunction with the financial statements and notes thereto included in
      the Company's  Annual Report on Form 10-KSB/A for the year ended  December
      31, 1996.

      In the opinion of the Company's  management,  the  accompanying  condensed
      consolidated  financial statements contain all adjustments  (consisting of
      only  normal  recurring  adjustments)  necessary  to  present  fairly  the
      Company's  financial  position  as of June 30,  1997,  and the  results of
      operations  for the three and six months  ended June 30, 1997 and 1996 and
      cash flows for the six months ended June 30, 1997 and 1996. The results of
      operations  for the three and six months  ended June 30, 1997 and 1996 are
      not necessarily indicative of the operating results for the full years.

      Prior to the closing of the  acquisitions of  Telenational  Communications
      Limited  Partnership  ("TNC")  (see Note 2) and The Wallace  Wade  Company
      ("WWC") (see Note 8), the Company was a development  stage  enterprise and
      devoted  substantially  all of its efforts to  identifying  and  acquiring
      businesses,  developing a public market for its stock and raising capital.
      With the closing of the  acquisitions  of TNC and WWC, the Company now has
      operating  assets and continuing  operations.  Accordingly,  the financial
      statement  presentation  and disclosures  required for  development  stage
      enterprises have been omitted.

      Principles of Consolidation
      ---------------------------
      The accompanying  condensed  consolidated financial statements include the
      accounts of WorldPort and its wholly-owned  subsidiaries after elimination
      of all significant intercompany accounts and transactions.

                                       6

<PAGE>

      Property and Equipment
      ----------------------
      Property and equipment are carried at cost.  Expenditures  for  additions,
      improvements  and  renewals  which add  significant  value to the asset or
      extend the life of the asset are capitalized. Expenditures for maintenance
      and repairs are charged to expense as incurred.  The Company  provides for
      depreciation  of property and  equipment  using the  straight-line  method
      based on the estimated useful lives of the assets ranging from three to 15
      years.

      Goodwill
      --------
      The  excess  purchase  price  over  fair  value  of  net  assets  acquired
      ("goodwill") is amortized using the straight-line method over 10 years.

      The Company  periodically  evaluates  the  recoverability  of goodwill and
      measures the amount of impairment, if any, by assessing current and future
      levels of income and cash flows as well as other factors, such as business
      trends and prospects and market and economic conditions.

      Revenue Recognition
      -------------------
      The Company  recognizes  revenue from its  telecommunications  services as
      such services are provided to its customers.

      Risk Factors
      ------------
      The Company is subject to various risks in  connection  with the operation
      of its  business  including,  among  other  things,  changes  in  external
      competitive market factors,  changes in the Company's business strategy or
      an inability to execute its strategy due to  unanticipated  changes in the
      market,  the  Company's  lack  of  liquidity  and  operating  history  and
      anticipated  working  capital or other  cash  requirements  including  the
      Company's  current  working capital deficit and dependence upon additional
      capital investment.

      Funding of the  Company's  working  capital  deficit,  current  and future
      operating  losses and  expansion of the Company  will require  substantial
      continuing  capital  investment.  The Company's  strategy is to fund these
      cash requirements  through debt facilities or additional equity financing.
      Although  the Company has been able to arrange debt  facilities  or equity
      financing  to date,  there can be no  assurance  that  sufficient  debt or
      equity  financing  will  continue to be available in the future or that it
      will be available on terms  acceptable  to the Company.  Failure to obtain
      sufficient  capital could materially affect the Company's  acquisition and
      operating  strategies.  The Company  expects  that future  financing  will
      include  equity  placements;  however,  no assurance can be given that the
      Company will be able to obtain  additional  financing on reasonable terms,
      if at all (see Note 6).

      Pending Accounting Pronouncement
      --------------------------------
      In March 1997, the Financial  Accounting  Standards Board issued Statement
      of Financial  Accounting  Standard No. 128,  Earnings Per Share ("SFAS No.
      128").  SFAS No. 128  replaces  Accounting  Principles  Board  Opinion 15,
      Earnings Per Share,  and simplifies the computation of earnings (loss) per
      share ("EPS") by replacing the presentation of primary EPS with basic EPS,
      which is computed by dividing income  available to common  stockholders by
      the  weighted-average  number of common shares outstanding for the period.
      SFAS No. 128 also requires dual  presentation  of basic and diluted EPS on
      the  face of the  income  statement  for  entities  with  complex  capital
      structures,  and a reconciliation of the numerator and denominator used in
      the basic EPS computation to the diluted EPS  computation's  numerator and
      denominator. SFAS No. 128 is effective for financial statements issued for
      periods ending after December 15, 1997, including interim periods. Earlier

                                       7

<PAGE>

      application is not permitted.  Restatement of all prior period EPS data is
      required. Management of the Company believes that the adoption of SFAS No.
      128 will not have a material effect on previously reported EPS.

      Certain Reclassifications
      -------------------------
      Certain reclassifications have been made to amounts previously reported to
      conform to current year presentation.

(2)   TNC ACQUISITION
      ---------------
      On June 20, 1997, the Company  completed the acquisition of  substantially
      all of the  telecommunications  assets  and  operations  of TNC (the  "TNC
      Acquisition")  pursuant to that certain  Asset  Purchase  Agreement  dated
      April 23,  1997 (as  amended  by  Amendment  No. 1 to the  Asset  Purchase
      Agreement   dated  June  20,  1997,   collectively   the  "Asset  Purchase
      Agreement").  The  results  of  operations  of  TNC  are  included  in the
      financial statements of the Company from the date of acquisition, June 20,
      1997.

      The  assets and  operations  of TNC were  purchased  in  exchange  for (i)
      3,750,000  shares of the Company's Common Stock (of which 1,000,000 shares
      are being held  pursuant to an escrow  agreement for a period of 18 months
      following  the  closing  subject to  certain  purchase  price  adjustments
      described  below)  and (ii)  the  assumption  by the  Company  of  certain
      indebtedness of TNC up to a maximum of $4.6 million.  The purchased assets
      include telecommunications switches and other network equipment,  customer
      and vendor  contracts,  an FCC  section  214 common  carrier  license,  an
      operator  services  center and other  assets  sufficient  to continue  the
      ongoing  business of TNC. The FCC section 214 common carrier license gives
      the  Company  the  authority  to resell both  international  switched  and
      private line services of authorized carriers.  The final purchase price is
      subject to  adjustment  if (i)  liabilities  in excess of $4.6 million are
      assumed,  (ii) the Company is required to invoke certain  indemnifications
      by TNC,  (iii)  there are  certain  expense  overruns,  or (iv)  there are
      certain rejected contracts. In addition, certain creditors of TNC have the
      option to  convert  all or a  portion  of their  debt  into  shares of the
      Company's  Common  Stock.  In  connection  with the TNC  Acquisition,  the
      Company incurred  approximately  $254,000 of transaction  costs which were
      capitalized  as part of the purchase  price.  Of this amount,  $150,000 is
      payable  to Maroon  Bells  Capital  Partners  ("MBCP")  as a  mergers  and
      acquisitions success fee ("M&A Success Fee") (see Note 7).

      The TNC  Acquisition  was  accounted  for  using  the  purchase  method of
      accounting  and is  subject  to  certain  purchase  price  adjustments  as
      discussed  above.  The allocation of purchase price to the assets acquired
      and liabilities assumed in the transaction has been initially assigned and
      recorded based on  preliminary  estimates of fair value and may be revised
      as  additional  information  concerning  the  valuation of such assets and
      liabilities becomes available.

      The fair value of assets  acquired and  liabilities  assumed in connection
      with the TNC Acquisition is summarized as follows (in thousands):

             Current assets                                      $   804
             Property and equipment                                1,121
             Goodwill                                              5,742
                                                                   -----

      Prior to the closing of the TNC Acquisition, the Company loaned $1,178,000
      to TNC to provide  TNC with  working  capital.  This amount was assumed in
      connection with the acquisition.

      Set forth below are unaudited pro forma combined  results of operations of
      the Company and TNC for the six months  ended June 30, 1997 and 1996.  The
      unaudited  pro  forma  data  is  presented  on  the  basis  that  the  TNC
      Acquisition  took place at the  beginning  of each of the  fiscal  periods
      ended June 30, 1997 and 1996 (in thousands, except per share amounts):

                                                              1997     1996

      Pro forma  adjustments  included in the amounts above primarily relate to:
      (i) adjustment for pro forma goodwill amortization expense using a 10-year
      estimated life and (ii) adjustment for non-recurring  management fees paid
      to the General Partner of TNC.

      The  summarized  pro forma  information  is based on estimates,  available
      information  and  certain  assumptions  and may be revised  as  additional
      information  becomes available.  The pro forma financial  information does
      not purport to represent  what the Company's  results of operations  would
      have been if the TNC Acquisition had occurred on the date assumed or to be
      representative of the results of operations for any future period. Neither
      the expected  benefits or cost  reductions  anticipated by the Company nor
      the future corporate  overhead costs of the Company have been reflected in
      the above pro forma information.

<PAGE>

      In  connection  with the TNC  Acquisition,  the Company  assumed a secured
      promissory  note  payable to Value  Partners,  Ltd. The note is payable in
      installments of $100,000 per month plus accrued  interest at a rate of 14%
      per annum  beginning  September 1, 1997. The note is secured by all of the
      assets acquired by the Company in connection with the TNC Acquisition.

      The Company also assumed  $300,000 of unsecured  notes  payable to certain
      individuals  in  connection  with the TNC  Acquisition.  These  notes  are
      payable  on demand  and bear  interest  at rates  ranging  from 12% - 15%.
      Holders  of certain  of these  notes have the option to convert  them into
      shares of the Company's Common Stock (see Note 2).

      Capital Lease Obligations
      -------------------------
      In  connection  with the TNC  Acquisition,  the  Company  assumed  certain
      capital lease obligations.  The carrying value of the assets under capital
      lease is as follows:

             Property and equipment                 $ 440,737
             Less:  Accumulated amortization           (3,930)

(5)   COMMITMENTS AND CONTINGENCIES
      -----------------------------
      From time to time,  the Company is involved in various  lawsuits or claims
      arising from the normal course of business.  In the opinion of management,
      none of these  lawsuits or claims will have a material  adverse  effect on
      the financial statements or results of operations of the Company.

(6)   SERIES A PREFERRED STOCK OFFERING
      ---------------------------------
      On May 8, 1997, the Company initiated a Private Placement  Offering of the
      Company's  Series A  Preferred  Stock for $3.00 per share  pursuant  to an
      Offering  Memorandum  (the "Series A Preferred Stock  Offering").  On July
      25,  1997,  the  offering  price was reduced to $2.25 per share. There can
      be no assurance  that the Company will be successful  in  completing  this
      offering.

      WorldPort  Acquisitions,  Inc., ("WAI") completed a merger of WWC into WAI
      pursuant to that certain Agreement and Plan of Merger dated April 20, 1997
      (the "WWC Acquisition"). WWC was a telecommunications marketing consulting
      firm which  produced  and  implemented  marketing  strategies  for clients

ITEM 2.     MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
            CONDITION AND RESULTS OF OPERATIONS

Management's  Discussion  and  Analysis of  Financial  Condition  and Results of
Operations  ("MD&A")  contains  many  "forward-looking  statements"  within  the
meaning of the  Private  Securities  Litigation  Reform Act of 1995,  including,
among  others  (i)  results of  operations  (including  expected  changes in the
Company's revenues and strategy) and (ii) the Series A Preferred Stock Offering.

These  forward-looking  statements  are based largely on the  Company's  current
expectations  and are  subject  to a number of risks and  uncertainties.  Actual
results could differ materially from these forward-looking statements. Important
factors to consider in evaluating such  forward-looking  statements  include (i)
the  changes  in  external  competitive  market  factors;  (ii)  changes  in the
Company's  internal budgeting process which might impact trends in the Company's
results  of  operations;   (iii)  anticipated  working  capital  or  other  cash
requirements; (iv) changes in the Company's business strategy or an inability to
execute its strategy  due to  unanticipated  changes in the market;  (v) various
competitive factors that may prevent the Company from competing  successfully in
the market  place;  (vi) the Company's  lack of  liquidity;  (vii) the lack of a
public market for the Company's Series A Preferred  Stock;  (viii) the Company's
lack of operating history;  and (ix) the Company's ability to attract and retain
key personnel with the skills and expertise  necessary to manage its growth.  In
light of these  risks  and  uncertainties,  there can be no  assurance  that the
events  contemplated by the  forward-looking  statements  contained in this Form
10-QSB will in fact occur.

The  following  discussion  should  be read in  conjunction  with the  Condensed
Consolidated  Financial  Statements  and Notes thereto  included under Item 1 of
this  Form  10-QSB.  In  addition,  reference  should  be made to the  Financial
Statements and Notes thereto and related Management's Discussion and Analysis of
Financial  Condition and Results of Operations  included in the Company's Annual
Report on Form 10-KSB/A for the year ended December 31, 1996.

General
- - -------
WorldPort is a facilities-based  network provider of enhanced  international and
domestic  telecommunication  services.  The Company operates  telecommunications
switches  and an operator  services  platform in Omaha,  Nebraska  from which it
provides  enhanced  services,  such as global  calling  cards and  international
prepaid  debit  cards to  individuals,  small  businesses  and  large  corporate
customers primarily in the United States,  Western Europe and Latin America. The
Company's  strategy is to expand its  business  through both  internal  business
development  and  the  strategic  acquisitions  of  telecommunication   services
companies, such as TNC and WWC. See "TNC Acquisition" and "Subsequent Events".

Results of Operations
- - ---------------------
Prior to its  acquisition  of the assets and  on-going  operations  of TNC,  the
Company was a development  stage company that had not generated  revenues  other
than interest income since inception. During the three and six months ended June
30,  1997,  the  Company   incurred   losses  of  $(375,226)   and   $(637,520),
respectively,  compared to $(115,385) and $(120,170)  during the same periods in
1996. Included in the losses incurred during the three and six months ended June
30, 1997 are the operating  results of TNC  subsequent to the closing of the TNC
Acquisition.  Prior to the TNC  Acquisition,  TNC had  experienced  a history of
operating  losses and cash flow  deficiencies.  The Company is  currently in the
process of evaluating the assets, operations,  vendor and customer relationships
of TNC in order to refocus the sales and marketing of the Company's  products to
coincide  with  new   distribution  and  carrier   agreements   currently  under
negotiation  by the  Company.  While the  Company  is now  implementing  certain
revenue enhancement and cost reduction initiatives, the Company anticipates that
it will continue to incur operating  losses and cash flow  deficiencies  for the
foreseeable future. See "Liquidity and Capital Resources".

Revenues
- - --------
Revenues  for the  three and six  months  ended  June 30,  1997,  were  $188,549
compared to $0 for the three and six month ended June 30, 1996.  The increase in

                                       12

<PAGE>

revenues  was  solely  due to the  inclusion  of the  operating  results  of TNC
subsequent to the closing of the TNC Acquisition on June 20, 1997.

Gross Margin
- - ------------
Gross  margin for the three and six months  ended June 30,  1997,  was  $(5,863)
compared to $0 for the three and six months ended June 30, 1996. The decrease in
gross  margin was solely due to the  inclusion of the  operating  results of TNC
subsequent to the closing of the TNC Acquisition on June 20, 1997.

Selling, General and Administrative Expenses
- - --------------------------------------------
Selling, general and administrative expenses increased to $363,679 from $115,385
and to $652,648  from  $120,296 for the three and six months ended June 30, 1997
and  1996,  respectively.  The  increase  was  due  to  (i)  increased  business
development and acquisition activity, (ii) the establishment and staffing of the
Company's corporate offices and (iii) the inclusion of the selling,  general and
administrative  expenses of TNC subsequent to the closing of the TNC Acquisition
on June 20, 1997.

Interest Income (Expense)
- - -------------------------
Interest  income  increased  to $29,827 from $0 and to $59,786 from $126 for the
three and six months  ended June 30, 1997 and 1996,  respectively.  The increase
was  due  to  the  interest  from  (i)  a  note   receivable  from  Global  Star
International,  Inc.  (the "GSI Note")  which was paid in full on March 6, 1997,
(ii) the note receivable from Com Tech  International  Corporation  ("Com Tech")
and (iii) the note  receivable  from TNC prior to the Company's  acquisition  of
TNC. See "Liquidity and Capital Resources".

Pro Forma Results (See Note 2 to the Condensed Consolidated Financial
Statements)
- - ---------------------------------------------------------------------

Pro forma  revenues  for the six months  ended June 30, 1997 were  approximately
$3,766,000  compared to  approximately  $5,703,000 for the six months ended June
30, 1996. The decrease in revenues was due primarily to the  restructuring  of a
contract  effective  January 1, 1997,  with a  distributor  who is a significant
customer of TNC.  Prior to January 1, 1997,  the  contract was  structured  as a
retail contract  whereby TNC billed the distributor on a retail basis and paid a
commission to the distributor based on the retail billings. Effective January 1,
1997,  the  contract was changed to a wholesale  contract  whereby TNC bills the
distributor on a wholesale basis and pays no commissions to the distributor.

Through  its  renegotiation  of the  distribution  agreement,  the  Company  has
terminated  the exclusive  distribution  provisions  of the prior  agreement and
gained the ability to directly market its calling cards and pre-paid phone cards
in the  market  served  by  the  distributor.  This  contract  renegotiation  is
consistent with the Company's  strategy to develop new  distribution  agreements
consistent  with  new  carrier  agreements  under  development  by  the  Company
worldwide.

Pro forma loss from continuing operations for the six months ended June 30, 1997
was approximately  $(2,785,000)  compared to approximately  $(1,272,000) for the
six months ended June 30, 1996. The increase in loss from continuing  operations
was due primarily to (i)  increased  network  costs  associated  with changes in
TNC's vendor  contracts  (ii) the  write-off of a receivable  from a significant
customer  and  (iii)  increased  selling,   general  and  administrative   costs
associated   with  the  closing  of  the  TNC  Acquisition  and  the  subsequent
implementation of new operating and  administrative  procedures,  as well as the
Company's  increased  business  development  and  acquisition  activity  and the
establishment and staffing of the Company's  corporate offices.  These increases
were  partially  offset by decreased  commission  expenses  associated  with the
restructuring of the contract discussed above.

Liquidity and Capital Resources
- - -------------------------------
The Company has a working  capital  deficit of  $1,691,954  as of June 30, 1997,
compared to a working  capital  surplus of $2,259,416 at December 31, 1996.  The
working  capital  deficit is due to the assumption of liabilities in conjunction
with  the TNC  Acquisition,  the  majority  of which  were  trade  payables  and
short-term debt obligations. Trade receivables increased to $652,257 at June 30,
1997, from $0 at December 31, 1996 due to the TNC Acquisition.


Operations used $659,819 during the six months ended June 30, 1997,  compared to
$119,435  for  the  six  months ended June 30, 1996.  Investing  activities used

                                       13

<PAGE>

$238,287  during the six months ended June 30, 1997,  compared to $0 for the six
months  ended  June  30,  1996.  Investing  activities  consisted  primarily  of
collection  of the GSI Note and a portion  of the Com Tech  Note  offset by cash
advances  to TNC to  fund  working  capital  prior  to the  closing  of the  TNC
Acquisition. Financing activities used $250,028 during the six months ended June
30,  1997,  while  generating  $114,400  for the six months ended June 30, 1996.
Financing activities for the six months ended June 30, 1997, consisted primarily
of payments on short-term  debt  obligations  assumed in connection with the TNC
Acquisition.  Financing  activities  for the six  months  ended  June  30,  1996
consisted of proceeds from the issuance of Common Stock.

In addition to trade payables and vendor obligations  assumed in connection with
the TNC  Acquisition,  the Company assumed a secured  promissory note payable to
Value Partners, Ltd. which is payable in installments of $100,000 per month plus
accrued  interest at a rate of 14% per annum  beginning  September 1, 1997.  The
note is secured by all of the assets  acquired by the Company in connection with
the TNC  Acquisition.  The Company  also  assumed  $300,000 of  unsecured  notes
payable  to  certain  individuals.  These  notes are  payable on demand and bear
interest at rates ranging from 12% - 15%. Holders of certain of these notes have
the option to convert them into shares of the Company's Common Stock.

Funding of the working capital deficit,  current and future operating losses and
expansion of the Company will require substantial continuing capital investment.
The  Company's  strategy  is  to  fund  these  cash  requirements  through  debt
facilities or additional equity financing. Although the Company has been able to
arrange debt facilities or equity  financing to date,  there can be no assurance
that  sufficient  debt or equity  financing will continue to be available in the
future  or that it  will  be  available  on  terms  acceptable  to the  Company.
Substantial additional debt or equity financing may be needed for the Company to
achieve its  short-term  and long-term  business  objectives.  Failure to obtain
sufficient  capital  could  materially  affect  the  Company's  acquisition  and
operating  strategies.  The Company  expects that future  financing will include
equity placements;  however,  no assurance can be given that the Company will be
able to obtain additional  financing on reasonable terms, if at all. See "Series
A Preferred Stock Offering" and "Subsequent Events".

Effective  April 14, 1997, the Company and Com Tech entered into an agreement to
settle any and all  claims  that have been or could  have been  asserted  in the
lawsuit  entitled  WorldPort  Communications,   Inc.,  formerly  known  as  Sage
Resources,  Inc., a Delaware  corporation,  plaintiff v. Com Tech  International
Corporation,  a Washington  corporation,  defendant,  Case No.  C96-4055SBA (the
"Settlement  Agreement").  Pursuant to the Settlement Agreement, Com Tech agreed
to pay the Company all  amounts due under a $500,000  promissory  note (the "Com
Tech  Note").  Com Tech agreed to pay $150,000  plus accrued  interest on May 1,
1997. Com Tech also agreed to make six payments to the Company, on or before the
10th day of each month,  beginning  June 10, 1997 through  November  1997.  Each
payment  consists of (i) $58,333.33 of principal,  (ii) accrued  interest on the
outstanding  balance at twelve  percent  (12%) per annum,  and (iii)  $6,089.03,
which  represents  one-sixth of the total costs of litigation and other expenses
owing.  As of August 14,  1997,  Com Tech has paid the Company  $401,489,  which
represents   $325,000  of  principal   and  $76,489  of  accrued   interest  and
reimbursement of litigation expenses and is current on its obligations under the
Settlement Agreement.

On May 8, 1997,  the Company  initiated a Private  Placement  Offering for up to
$5,000,000 under Regulation D of 1,666,667 shares of Series A Preferred Stock at
$3.00  per  share  pursuant  to an  Offering  Memorandum  dated May 8, 1997 (the
"Series A Preferred Stock  Offering").  Holders of Series A Preferred Stock will
be entitled to receive annual cumulative  dividends of 8%, payable in cash or in
shares of Common Stock of the Company, at the Company's option, as and when such
dividends  are declared by the Company's  Board of  Directors.  No public market
exists  for the  Company's  Series A  Preferred  Stock and none is  expected  to
develop as a result of the Series A Preferred Stock Offering. The offer and sale
of the Series A Preferred Stock is not being registered under the Securities Act
of 1933, as amended, under U.S. or state securities laws or under the securities
laws of any other  jurisdictions,  and the Company's Series A Preferred Stock or
the Common  Stock into which it is  convertible  may not be resold or  otherwise
transferred unless it is subsequently registered or an exemption from applicable
registration requirements is available.

On July 25,  1997, the  offering  price  was  reduced to $2.25 per share.  There
can be no assurance that the Company will be successful in completing the Series
A Preferred  Stock  Offering.

TNC Acquisition
- - ---------------
On June 20, 1997, the Company  completed the acquisition of substantially all of
the  telecommunications  assets  and  operations  of TNC  in  exchange  for  (i)
3,750,000  shares of the Company's  Common Stock (of which 1,000,000  shares are
being held pursuant to an escrow  agreement for a period of 18 months  following
the closing subject to certain purchase price  adjustments  described below) and
(ii) the  assumption  by the  Company  of  certain  indebtedness  of TNC up to a
maximum  of  $4.6  million.  The  purchased  assets  include  telecommunications
switches and other  network  equipment,  customer and vendor  contracts,  an FCC
section 214 common carrier license, an operator services center and other assets
sufficient  to continue the ongoing  business of TNC. The FCC section 214 common
carrier  license  gives the Company the  authority to resell both  international
switched and private line services of authorized  carriers.  The final  purchase
price is subject to adjustment if (i)  liabilities in excess of $4.6 million are
assumed, (ii) the Company is required to invoke certain indemnifications by TNC,
(iii) there are certain  expense  overruns,  or (iv) there are certain  rejected
contracts. In addition,  certain creditors of TNC have the option to convert all
or a portion of their debt into shares of the Company's  Common Stock.  Prior to
closing the TNC Acquisition, the Company loaned $1,178,000 to TNC to provide TNC
with working capital.  This amount was assumed by the Company in connection with
the acquisition. See "Liquidity and Capital Resources".

On April 29,  1997,  the  Company  and TNC entered  into a  Management  Services
Agreement,  wherein the Company provided to TNC day-to-day  executive management
services. The Management Services Agreement provides certain indemnifications to
WorldPort as well as a covenant not to sue or assert any claim or action against
the Company  arising from the services  provided by the Company  pursuant to the
Management Services Agreement. The Management Services Agreement terminated with
the closing of the TNC Acquisition on June 20, 1997.

The  acquired  telecommunications  switches and  operator  services  platform in
Omaha,  Nebraska  provide  enhanced  services,  such as global calling cards and
international  prepaid debit cards to  individuals,  small  businesses and large
corporate  customers  primarily in the United  States,  Western Europe and Latin
America.  Through the acquired  operator  services center,  the Company provides
multilingual  customer support.  The U.S. switching and operator services center
enables  customers in foreign  countries to take advantage of lower cost routing
and higher transmission  quality for international calls. The Company's services
are  currently  marketed  through  various  distribution  channels in the United
States, Western Europe and Latin America.

In conjunction  with the TNC  Acquisition,  the Company  entered into a two-year
employment  agreement with Mr. Bruce Burton to serve as the Company's  Executive
Vice  President and Chief  Operating  Officer.  Mr. Burton was the President and
Chief  Operating  Officer of TNC. The Company also entered into an eighteen (18)
month  consulting  agreement  with Mr.  Edmund  Blankenau,  the chief  executive
officer of the General Partner of TNC. Pursuant to his consulting agreement, Mr.
Blankenau  will earn a consulting fee of $7,000 per month during the term of his
agreement as well as being entitled to earn  additional  incentive  compensation
for  completed  acquisitions  and new  business  opportunities  based on certain
established criteria.

On July  28,  1997,  the  Company  and Mr.  Burton  agreed  to  terminate  his
employment  agreement and negotiate a consulting  agreement  acceptable to Mr.
Burton and the Company.  The terms of the  consulting  agreement  have not yet
been finalized between the Company and Mr. Burton.

On July 1, 1997, the Company  entered into a four-year  lease with a partnership
of which  Mr.  Blankenau  is a  partner,  for its  operating  center  in  Omaha,
Nebraska.  The Company's lease payment for the operating center,  which includes
basic  utilities,  is $8,992  per month for the first  three  months  subject to
quarterly operating expense adjustments beginning on October 1, 1997 through the
term of the lease.

Related Party Transactions

Pursuant to an Advisory  Agreement  between MBCP and the Company  dated March 7,
1997,  MBCP  earns  an M&A  Success  Fee in  connection  with  all  acquisitions
identified by MBCP which are consummated by the Company. The fee includes a base
plus an additional amount based on a percentage of the value of the transaction.
In  connection  with the TNC  Acquisition,  MBCP  earned an M&A  Success  Fee of

            (d) Litigation,  Proceedings,  Defaults.  There is no action,  suit,
investigation or proceeding  pending  against,  or to the knowledge of WorldPort
threatened against or affecting, WORLDPORT or its respective assets before or by
any  court  or  arbitrator  or  any  governmental  body,   agency,   department,
instrumentality or official. Worldport is not in violation of its Certificate of
Incorporation  or Bylaws,  and  WorldPort is not in violation  of, or in default
under any provision of any  applicable  law or  regulation or of any  agreement,
judgment,  injunction,  order, decree or other instrument binding upon WorldPort
which violation or default (i) would effect the validity of this Agreement,  the
Note, the Pledge Agreement or any other document or agreement  executed or to be
executed by WorldPort pursuant hereto or in connection  herewith,  or (ii) would
impair  the  ability  of  WorldPort  to  perform  in any  material  respect  the
obligations  which it has under the Loan Documents or any such other document or
agreement.

            (e)  Governmental  Regulation.  Except as  required  pursuant to the
Securities  Act of 1933,  as  amended  (the  "Act") and State  securities  laws,
WorldPort is not subject to any Federal or State law or regulation  limiting its
ability to execute or issue the Loan Documents.

            (f)  Ownership of Property.  WorldPort  has good record title in fee
simple  to,  or  valid  and  subsisting  leasehold  interests  in,  all its real
property,  and good  title to all its  other  property,  in each  case  which is
necessary or useful in the conduct of its business.  Each lease  agreement under
which  WorldPort  holds an  interest  in leased  property  is in full  force and
effect.

            (g) Documentation;  No Material Misstatements.  All of the necessary
documents  related to the consummation of this transaction have been provided by
WorldPort  to the Lender and are true,  correct  and  complete  in all  material
respects, and no written representation, warranty or statement made by WorldPort
in or pursuant to this Agreement contains or will contain, when made, any untrue
statement of a material  fact or omits or will omit to state any  material  fact
necessary to make such representation, warranty or statement not misleading to a
prospective  purchaser  of  securities  from  WorldPort,  who  is  seeking  full
information with respect to WorldPort.

      9.    Representations  and Warranties of Lender.  The Lender  represents
and warrants to Borrowers as follows:

            (a)  Authorization  and Execution.  The Lender has full legal right,
power,  and  authority   (including  the  due  authorization  by  all  necessary
partnership  action) to enter into this  Agreement  and to perform the  Lender's
obligations  hereunder without the need for the consent of any other person; and
this Agreement has been duly authorized,  executed and delivered and constitutes
the legal, valid and binding  obligation of the Lender  enforceable  against the
Lender in accordance with the terms hereof.

            (b) Risk of Loss. The Lender is in a financial  position to hold the
Note  until  maturity  and is able to bear the  economic  risk and  withstand  a
complete loss of investment in the Note.

- - --------------------------------------------------------------------------------
                                  FIRST AMENDED
                       LOAN MODIFICATION AGREEMENT, PAGE 7
<PAGE>

            (c)   Experience.  The  Lender  has such  knowledge  and  experience
in financial and business  matters that the Lender is capable of evaluating  the
merits  and  risks  of the  investment  in the  Note  and has the net  worth  to
undertake such risks.

            (d)   Advice.  The Lender has  obtained,  to  the  extent the Lender
has deemed necessary,  the Lender's own professional  advice with respect to the
risks  inherent  in the  investment  in the  Note,  and the  suitability  of the
investment  in the  Note  in  light  of the  Lender's  financial  condition  and
investment needs.

            (e) Suitable Investment.  The Lender believes that the investment in
the  Note  is  suitable  for the  Lender  based  upon  the  Lender's  investment
objectives and financial  needs, and the Lender has adequate means for providing
for the  Lender's  current  financial  needs  and has no need for  liquidity  of
investment with respect to the Note.

            (f) Risk Factors.  The Lender  realizes that (i) the purchase of the
Note is a long term  investment;  (ii) the Lender must bear the economic risk of
investment  until the Note matures and because the Note has not been  registered
under the Act,  the Note cannot be sold unless each is  subsequently  registered
under the Act or an exemption  from such  registration  is available;  and (iii)
there is presently no public  market for the Note and the Lender may not be able
to liquidate the Lender's  investment in the event of an emergency or pledge the
Note as collateral security for loans.

            (g) Own  Account.  The  Lender  acknowledges  that the Note is being
purchased  for the  Lender's  own  account  and for  investment  and without the
intention of reselling or  redistributing  the same, and that the Lender made no
agreement with others regarding any of such Note.

            (h)   No  Agreements.  The Lender has no  agreements  (written  or
oral),  arrangements,  understandings  or commitments  with any other investor
subscribing for Note.

            (i)   Accredited   Investor.   The   Lender   is  an   "accredited
investor" as defined under Regulation D under the Act.

            (j)   Entity  Representations.  The Lender was not  organized  for
the specific  purpose of acquiring  the Note and has total assets in excess of
$5,000,000.

      10. Securities Laws  Restrictions.  The Lender  acknowledges the Note will
not be sold or assigned  unless the Lender shall have obtained (i) an opinion of
counsel satisfactory to the Borrowers that such proposed disposition or transfer
lawfully may be made without the  registration  of such Note pursuant to the Act
and applicable state securities laws, or (ii) such registration.

      11.   Legend on Note.  The Lender  acknowledges  that the Note will each
bear a legend conspicuously endorsed reading substantially as follows:

- - --------------------------------------------------------------------------------
                                  FIRST AMENDED
                       LOAN MODIFICATION AGREEMENT, PAGE 8
<PAGE>

      THIS NOTE HAS NOT BEEN  REGISTERED  UNDER THE  SECURITIES  ACT OF 1933, AS
      AMENDED,  OR UNDER THE SECURITIES  LAWS OF ANY STATE.  THIS NOTE THEREFORE
      MAY NOT BE SOLD, TRANSFERRED,  ASSIGNED, PLEDGED, OR OTHERWISE DISTRIBUTED
      FOR  VALUE  IN THE  ABSENCE  OF  (i)  AN  OPINION  OF  COUNSEL  REASONABLY
      ACCEPTABLE TO THE MAKER THAT SUCH SALE,  TRANSFER,  ASSIGNMENT,  PLEDGE OR
      OTHER  DISTRIBUTION  IS  EXEMPT  FROM (OR NOT  OTHERWISE  SUBJECT  TO) THE
      REGISTRATION (OR  QUALIFICATION) AND PROSPECTUS  DELIVERY  REQUIREMENTS OF
      SUCH ACT OR LAWS, OR (ii) SUCH REGISTRATION OR QUALIFICATION.

      12.   Release  of  Lender.   Each  of  the  Borrowers  and   Telenational,
respectively,  on behalf of itself  and its  respective  partners  (limited  and
general) and the officers,  directors,  managers,  partners,  employees, agents,
attorneys,  representatives and affiliates, and respective heirs, successors and
assigns each (collectively, the "Releasing Parties"), hereby release and forever
discharge Lender and its predecessors, successors, assigns, officers, directors,
managers, shareholders,  employees, agents, attorneys,  representatives,  parent
corporations,  subsidiaries  and affiliates  and partners  (limited and general)
(collectively,  the "Released Parties") from, and waive and relinquish,  any and
all  actions,  causes  of  action,  suits,  debts,  controversies,   agreements,
promises, rights, variances,  trespasses, damages, judgments, executions, claims
and demands whatsoever,  in law, equity or otherwise, by reason of, arising from
or in connection  with, or directly or indirectly  attributable to, the Original
Note, the Telenational Documents,  the Collateral,  the Pledged Securities,  the
Loan Documents,  or the administration or enforcement  thereof, the negotiation,
execution,  and delivery of the Loan Documents, or any course of dealing between
any of the Released  Parties and any of the  Releasing  Parties,  in  connection
therewith  from the  beginning  of time  through  the date of  actual  execution
hereof.  It is  expressly  understood  and  agreed  that the  terms  hereof  are
contractual  and that the release  given  hereby  shall not be  construed  as an
admission of liability,  any liability being  expressly  denied on behalf of any
and all Released Parties.

      13. No Release By Lender.  Lender is not  releasing any claims of any kind
or nature in entering into this Agreement, including any claims arising pursuant
to the terms of the Telenational Note, unless specifically set forth herein, and
other than the  release of its  security  interest  in the  Pledged  Securities,
pursuant to the terms hereof.

      14. Claim Preserved.  Neither the execution of the Telenational  Documents
nor the Loan  Documents,  nor the  acceptance  by  Lender  of the  pledge of the
Pledged Securities pursuant to the Telenational Pledge Agreement nor the release
of such pledge of the Pledged  Securities  pursuant to the terms hereof shall be
deemed a waiver  of  rights,  claims  or  causes of action of any kind or nature
which the Lender may have related to the Pledged  Securities  or the  underlying
transaction pursuant to which Telenational acquired the Pledged Securities. This
provision  does not create any rights of action or claims  which Lender does not
otherwise have.

      15.   Representations  and  Warranties  True  at  the  Closing  Date.  The
representations  and warranties of each party hereto contained in this Agreement
shall be deemed to have been made  again at and as of the  Closing  Date as that

      17. Special  Notices to Borrowers.  THIS LOAN IS DUE IN FULL ON JANUARY 1,
1998. AT MATURITY,  YOU MUST PAY THE ENTIRE UNPAID PRINCIPAL BALANCE OF THE LOAN
AND ACCRUED  UNPAID  INTEREST  THEN DUE.  THE LENDER IS UNDER NO  OBLIGATION  TO
REFINANCE THE LOAN AT THAT TIME.  YOU WILL THEREFORE BE REQUIRED TO MAKE PAYMENT
OUT OF OTHER  ASSETS YOU MAY OWN,  OR YOU WILL HAVE TO FIND A LENDER  WILLING TO
LEND THE MONEY AT PREVAILING MARKET RATES, WHICH MAY BE CONSIDERABLY HIGHER THAN
THE INTEREST RATE ON THIS LOAN. IF YOU REFINANCE THIS LOAN AT MATURITY,  YOU MAY
HAVE TO PAY SOME OR ALL OF THE CLOSING COSTS NORMALLY ASSOCIATED WITH A NEW LOAN
EVEN IF YOU OBTAIN REFINANCING FROM THE SAME LENDER.

      18.  Costs and  Expenses.  Borrowers  agree to pay all costs and  expenses
incurred by Lender in connection  with the execution  and  consummation  of this
Agreement,  including,  without  limitation,  all  recording  costs of documents
evidencing the  continuation of the lien granted Lender in the  Collateral,  and
the fees and expenses of Lender's  counsel in the sum of  $22,800.00,  which sum
shall be paid on the Closing Date.

      19.   Continued  Effect.  Except  to the  extent  amended  hereby  or in
connection  herewith,  all  terms,  provisions,  and  conditions  of the  Loan
Documents  shall  remain  enforceable  and  binding in  accordance  with their
respective terms.

      20.   Governing Law. The terms and  provisions  hereof shall be governed
by and construed in accordance with the laws of the State of Texas.

      21.   Further  Amendments.  All of the terms and  provisions of the Loan
Documents are hereby amended and modified whereby  necessary,  even though not
specifically  addressed  herein,  so as  to  conform  to  the  amendments  and
modifications set forth herein.

      22. Binding Effect.  This Agreement shall be binding upon and inure to the
benefit of the respective successors and assigns of the parties hereto, and each
of the parties hereto hereby  represents,  warrants,  and covenants to the other
that the  persons  executing  this  Agreement  on behalf of such party have full

principal.

the subject matter hereof.

      24.   Headings.  The  headings of the sections  and  subsections  hereof
are inserted as a matter of  convenience  and for reference only and in no way
define,  limit or describe  the scope of this  Agreement or the meaning of any
provision hereof.

      25. Waivers.  The failure of any party to act to enforce rights  hereunder
shall not be deemed a waiver and shall not  preclude  enforcement  of any rights
hereunder. No waiver of any term or provision of this Agreement on the part of a
party shall be  effective  for any purpose  whatsoever  unless such waiver is in
writing and signed by such party.

      26. Invalid  Provisions.  If any provision of this Agreement is held to be
illegal,  invalid or unenforceable under present or future laws effective during
the terms hereof, such provision shall be fully severable.  This Agreement shall
be construed and enforced as if such illegal, invalid or unenforceable provision
had never  comprised a part hereof,  and the remaining  provisions  hereof shall
remain in full  force and  effect  and shall  not be  affected  by the  illegal,
invalid or unenforceable provision or by its severance herefrom. Furthermore, in
lieu of such illegal,  invalid or  unenforceable  provision there shall be added
automatically  as a part of this  Agreement a  provision  as similar in terms to
such  illegal,  invalid or  unenforceable  provision  as may be possible  and be
legal, valid and enforceable.

      27.  Notices.  Any  request,  demand,  authorization,  direction,  notice,
consent,  waiver,  instruction,  document  or other  communication  provided  or

benefit of the respective  heirs,  successors and assigns of the parties hereto,
and each of the parties hereto hereby represents, warrants, and covenants to the
other that the persons  executing  this  Agreement  on behalf of such party have
full authority,  power,  and  authorization to execute such document and to bind
its principal.

      31.   NOTICE OF INVALIDITY OF ORAL AGREEMENTS.  THIS WRITTEN  AGREEMENT,
THE LOAN  DOCUMENTS,  AND ALL EXHIBITS  HERETO  REPRESENT THE FINAL  AGREEMENT
BETWEEN  THE  PARTIES  AND MAY  NOT BE  CONTRADICTED  BY  EVIDENCE  OF  PRIOR,
CONTEMPORANEOUS,  OR SUBSEQUENT ORAL  AGREEMENTS OF THE PARTIES.  THERE ARE NO
UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

      32.  Usury.  All  agreements  between  Borrowers  and Lender,  whether now
existing or hereafter arising and whether written or oral, are hereby limited so
that in no contingency, whether by reason of demand or acceleration of the Final
Maturity  Date,  as that term is defined in the Note,  or  otherwise,  shall the
interest contracted for, charged,  received, paid or agreed to be paid to Lender
exceed  the  maximum  amount  permissible  under  the laws of the State of Texas
(hereinafter  the  "Applicable  Law").  If,  from any  circumstance  whatsoever,
interest  would  otherwise be payable to Lender in excess of the maximum  amount
permissible  under the Applicable  Law, the interest  payable to Lender shall be
reduced to the maximum amount  permissible under the Applicable Law, and if from
any circumstance  Lender shall ever receive anything of value deemed interest by
the  Applicable  Law in  excess  of the  maximum  amount  permissible  under the
Applicable  Law, an amount equal to the excessive  interest  shall be applied to
the reduction of the principal hereof and not to the payment of interest,  or if
such  excessive  amount of  interest  exceeds  the unpaid  balance of  principal
hereof, such excess shall be refunded to Borrowers.  All interest paid or agreed
to be paid to Lender shall,  to the extent  permitted by the Applicable  Law, be
amortized,  prorated, allocated and spread throughout the full period (including
any renewal or  extension)  until  payment in full of the  principal so that the
interest  hereon  for such full  period  shall not  exceed  the  maximum  amount
permissible  under the Applicable Law. Lender  expressly  disavows any intent to
contract for, charge or receive  interest in an amount which exceeds the maximum
amount permissible under the Applicable Law.

      33.  Counterparts.  This Agreement may be executed in separate or multiple
counterparts by the parties, and all of such counterparts shall be considered as
one and the same instrument  notwithstanding the fact that various  counterparts
are signed by only one or more of the parties,  and all of such Agreements shall
be deemed but one and the same Agreement.

                  SECOND AMENDED AND RESTATED SENIOR SECURED
                            PROMISSORY NOTE, PAGE 1
<PAGE>

      (a) The outstanding principal balance hereof shall bear simple interest at
the rate of the lesser of fifteen  percent (15%) per annum through and including
June 19, 1997 or the Highest Lawful Rate, as defined herein, and commencing June
20, 1997,  the lesser of fourteen  percent (14%) per annum or the Highest Lawful
Rate, as defined herein (the "Regular  Rate"),  computed daily on the basis of a
360 day year  consisting of twelve 30-day months for each day all or any part of
the principal  balance hereof shall remain  outstanding,  but to the extent such
computation  of interest  might cause the rate of interest which this Note bears
to exceed the Highest Lawful Rate,  such interest shall be computed on the basis
of a three hundred  sixty-five (365) day or a three hundred  sixty-six (366) day
year, as the case may be. If any installment of principal and/or interest is not
paid on or before  ten (10) days  following  the date it is due or if the entire
unpaid  principal  balance and accrued unpaid  interest is not paid on or before
the  earlier  to occur of the Final  Maturity  Date,  as defined  below,  or any
acceleration  of payment  permitted  hereby,  all  unpaid  amounts of this Note,
including  principal and interest,  shall  thereafter  bear simple interest at a
default rate of the lesser of seventeen  percent ( 17%) per annum or the Highest
Lawful Rate as defined herein .


      (b) "Highest  Lawful Rate" shall mean at the  particular  time in question
the  maximum  rate of  interest  which,  under  Applicable  Law,  Payee  is then
permitted to charge Maker on this Note. "Applicable Law" shall mean (i) the laws
of the United States of America applicable to contracts made or performed in the
State  of  Texas,  now or at any time  hereafter  prescribing  maximum  rates of
interest or  eliminating  maximum  rates of interest on loans and  extensions of
credit,  (ii) the laws of the  State of  Texas  including,  without  limitation,
Article 5069-1.04 of the Texas Revised Civil Statutes Annotated, as the same may
be amended  from time to time  ("Article  1.04"),  now or at any time  hereafter
prescribing or eliminating  maximum rates of interest on loans and extensions of
credit,  and (iii) any other laws at any time  applicable  to contracts  made or
performed  in the State of Texas which  permit a higher  interest  rate  ceiling
hereunder. If the maximum rate of interest which, under Applicable Law, Payee is
permitted to charge  Maker on this Note shall change after the date hereof,  the
Highest Lawful Rate shall be automatically  increased or decreased,  as the case
may be,  from time to time as the  effective  date of each change in the Highest
Lawful Rate without  notice to Maker.  For purposes of  determining  the Highest
Lawful Rate under the Applicable Law of the State of Texas,  the applicable rate
ceiling  shall be the  indicated  rate  ceiling  described  in and  computed  in
accordance  with the  provisions of section  (a)(1) of Article  1.04;  provided,
however, that in determining the Highest Lawful Rate, all fees and other charges
contracted  for,  charged  or  received  by  Payee in  connection  with the loan
evidenced by this Note which are either deemed interest under  Applicable Law or
required under  Applicable Law to be deducted from the principal  balance hereof
to  determine  the rate of  interest  charged  by this Note  shall be taken into
account.  To the extent permitted by Applicable Law, Payee may from time to time
substitute for the "indicated rate ceiling"  referred to above any ceiling under
Article  1.04 or any other  statute  and  revise  the rate,  index,  formula  or
provision of law used to compute the rate hereunder as provided therein.


      (c) All  agreements  between  Maker and Payee,  whether  now  existing  or
hereafter  arising and whether written or oral, are hereby limited so that in no

                             PROMISSORY NOTE, PAGE 2
<PAGE>

contingency,  whether by reason of demand or  acceleration of the Final Maturity
Date or otherwise, shall the interest contracted for, charged, received, paid or
agreed  to be  paid  to  Payee  exceed  the  maximum  amount  permissible  under
Applicable Law. If, from any circumstance  whatsoever,  interest would otherwise
be  payable  to Payee in  excess of the  maximum  amount  permissible  under the
Applicable  Law, the  interest  payable to Payee shall be reduced to the maximum
amount  permissible under the Applicable Law, and if from any circumstance Payee
shall ever receive  anything of value deemed  interest by the  Applicable Law in
excess of the maximum amount  permissible  under the  Applicable  Law, an amount
equal  to the  excessive  interest  shall be  applied  to the  reduction  of the
principal hereof and not to the payment of interest, or if such excessive amount
of interest exceeds the unpaid balance of principal hereof, such excess shall be
refunded to Maker. All interest paid or agreed to be paid to Payee shall, to the
extent  permitted by the Applicable Law, be amortized,  prorated,  allocated and
spread  throughout the full period  (including  any renewal or extension)  until
payment  in full of the  principal  so that the  interest  hereon  for such full
period shall not exceed the maximum amount permissible under the Applicable Law.
Payee expressly  disavows any intent to contract for, charge or receive interest
in an amount which exceeds the maximum amount  permissible  under the Applicable
Law. This paragraph shall control all agreements between Maker and Payee.

3. Pledge  Agreement.  Maker shall,  upon  execution of this Note and as partial
consideration for permitting the amendment, renewal, reinstatement,  replacement
and  extension of the  Telenational  Note,  as amended,  execute and cause to be
delivered to Bergman, Yonks, Stein & Bird, L.L.P., to the benefit of Payee, that
certain First Amended Pledge and Security  Agreement  (the APledge  Agreement@),

4. Payments.  All accrued unpaid interest through June 19, 1997 in the amount of
$15,880.79  together with unpaid principal in the sum of $262,278.06  (which sum
shall reduce the unpaid  principal  obligation of the Note from  $762,278.06  to
$500,000) shall be due and payable June 23, 1997.  Commencing  September 1, 1997
and on the first day of each of the four successive  calendar months thereafter,

hereunder,  together with accrued  unpaid  interest due on such date of payment.
All accrued unpaid  interest,  together with all unpaid  principal and any other
sums due pursuant to the terms  hereof shall be due and payable  January 1, 1998
(the "Final Maturity Date").  In addition,  Maker shall, not later than June 23,
1997,  pay  attorney's  fees,  costs  and  expenses  incurred  by  Payee  in the
restructuring, enforcement and collection of the Telenational Note. All payments

thereof,  directly to the Holder of the Note at the address of such Holder shown

      construed  either as a consent by Secured  Party to the  validity  of such
      encumbrances  or as a waiver of  Secured  Party's  right to  contest  such
      encumbrances.

            (v) No  default  exists,  and no event  which  with  notice  or  the
      passage of time or both,  would  constitute a default under the Collateral
      by any part thereto, and there are no offsets, claims or defenses  against
      the  obligations evidenced by the Collateral, except  as may be  expressly
      set forth in Exhibit "B" annexed hereto.

            (vi)  The  Security   Interest   constitutes  a  valid  and,  upon
      delivery of documents necessary  to perfect the Secured  Party=s  security
      interest  in  the  Collateral,  a  perfected  security   interest  in  the
      Collateral for payment and performance of the Secured Obligations, subject
      only to those liens and encumbrances of record as set forth in Exhibit "B"
      attached hereto and by this reference incorporated herein.

      All  representations  and  warranties  of Pledgor  contained  herein shall
survive  the  execution,  delivery  and  performance  of  this  Agreement  until
termination of this Agreement under Section 20.

      Section 8. Release of Collateral.  The Pledgor shall not sell or otherwise
dispose of the Collateral,  or any part thereof or any interest therein.  If the
Collateral,  or any part thereof,  is sold or otherwise disposed of in violation
of these  provisions,  the Security Interest of the Secured Party shall continue
in such  Collateral  or any  part  thereof  notwithstanding  such  sale or other
disposition,  and Pledgor will deliver any proceeds thereof to the Secured Party
to be, at the option of the Secured Party, held as Collateral hereunder,  and/or
be applied to the obligations of the Pledgor.

      Section  9.  Secured  Party  Appointed  Attorney-in-Fact.  Pledgor  hereby
irrevocably appoints the Secured Party as Pledgor's attorney-in-fact,  with full
authority  in the place and stead of any Pledgor  and in its name or  otherwise,
from time to time in the Secured Party's  discretion,  to take any action and to
execute any instrument that the Secured Party may deem  reasonably  necessary or
advisable to  accomplish  the  purposes of this  Agreement,  including,  without
limitation,  to receive,  endorse and collect all  instruments  made  payable to
Pledgor  representing any dividend,  interest  payment or other  distribution in
respect of the Collateral or any part thereof and to give full discharge for the
same, when and to the extent permitted by this Agreement.

      Section 10. Secured Party May Perform.  Upon the occurrence and during the
continuance of an Event of Default (including an Event of Default resulting from
a failure to perform any agreement  contained  herein),  if the Pledgor fails to
perform any agreement contained herein, the Secured Party may itself perform, or
cause  performance  of, such  agreement,  and the expenses of the Secured  Party
incurred in connection therewith shall be payable by Pledgor under Section 15.

      Section 11. Reasonable Care. The Secured Party shall have an obligation to
exercise reasonable care with respect to Collateral in its possession; provided,
however,  that the Secured  Party shall be deemed to have  exercised  reasonable
care if the Collateral is accorded  treatment  substantially  comparable to that
which the Secured Party accords its own property or treatment  substantially  in
accordance  with actions  requested by Pledgor in writing  (although the Secured
Party shall not be obligated to comply with any such  requests and no failure to
do so shall be deemed to be a failure to exercise reasonable care).

      Section 12.  Events of Default

      The  occurrence  of any one or more of the following  events  (hereinafter
referred  to as AEvents  of  Default@)  shall  constitute  a default  hereunder,
whether  such  occurrence  is  voluntary  or  involuntary  or comes  about or is
effected by operation of law or pursuant to or in compliance  with any judgment,
decree  or  order  of  any  court  or  any  order,  rule  or  regulation  of any
administrative or governmental authority:

            (a) If a default in the payment of any  principal  or interest due
            under the Note shall occur; or

            (b) If a failure to pay, perform or observe any covenant, agreement,
            term or provision of the Loan  Documents,  or any other agreement or
            arrangement now or hereafter entered into between the parties to the
            Loan Documents shall occur; or

            (c) If any Event of Default  shall occur under the terms of the Note
            or the Loan Agreement.

            (d)  If  there  shall  occur  any  reduction  in  the  value  of the
            Collateral  or any  act of any of the  Pledgor  which  imperils  the
            prospect  of the full  performance  or  satisfaction  of the Secured
            Obligations; or

            (e)  If all  of or  any  part  of  the  Collateral  shall  be  sold,
            transferred   or   assigned,   or  shall  be   further   encumbered,
            hypothecated,  mortgaged,  or  made  subject  to any  other  lien or
            security  interest,  without  the prior  written  consent of Secured
            Party.

      Section 14.  Remedies

      If upon or after the occurrence of any Event of Default, the Secured Party
elects to exercise  remedies under this  Agreement  (the  occurrence of any such

- - --------------------------------------------------------------------------------
             FIRST AMENDED PLEDGE AND SECURITY AGREEMENT, PAGE 6
<PAGE>

event shall be  referred  to as an  "Acceleration"),  then upon  minimum  notice
required by applicable law the Secured  Obligations shall immediately become due
and payable in full without notice or demand and the following  provisions shall
apply:

            (a) The  Secured  Party  may,  with or  without  notice to  Pledgor,
            foreclose  the security  interest  created  herein by any  available
            judicial  procedure,  or take possession of the  Collateral,  or any
            portion  thereof,  with or without judicial  process,  and enter any
            premises  where the  Collateral  may be located  for the  purpose of
            taking  possession  of or removing the same,  or rendering  the same
            unusable,  or  disposing of the  Collateral  on such  premises,  and
            Pledgor agrees not to resist or interfere therewith;

            (b) The Secured  Party may require  Pledgor to prepare,  assemble or
            collect the Collateral,  at Pledgor's own expense, and make the same
            available  to  Secured  Party at such  place as  Secured  Party  may
            designate, whether at Pledgor's premises or elsewhere;

            (c)  The  Secured  Party  may  exercise  (in  compliance   with  all
            applicable  securities  laws)  in  respect  of  the  Collateral,  in
            addition  to other  rights  and  remedies  provided  for  herein  or
            otherwise  available to it, all the rights and remedies of a secured
            party after default under the Uniform  Commercial  Code in effect in
            the State of Texas at that  time,  and the  Secured  Party may also,
            without  notice  except as  specified  below,  sell with or  without
            representations or warranties, the Collateral or any part thereof in
            one or more parcels at public or private sale, at any exchange, over
            the  counter or at the Secured  Party's  offices or  elsewhere,  for
            cash, on credit or for future delivery,  and at such price or prices
            and upon  such  other  terms as the  Secured  Party  may in its sole
            discretion deem commercially  reasonable or otherwise in such manner
            as necessary to comply with applicable  federal and state securities
            laws.  Upon  consummation  of any such sale, the Secured Party shall
            have the right to assign,  transfer and deliver to the  purchaser or
            purchasers  at any  such  sale and such  purchasers  shall  hold the
            property sold  absolutely,  free from any claim or right on the part
            of any Pledgor,  and Pledgor hereby waives (to the extent  permitted
            by Law) all rights of redemption,  stay or appraisal that it now has
            or may at any  time in the  future  have  under  any  rule of law or
            statute now existing or hereafter enacted;

            (d) The Secured  Party may execute and deliver  documents  of title,
            certificates  of origin,  or other evidence of payment,  shipment or
            storage of any  Collateral  or proceeds on behalf of and in the name
            of Pledgor;

            (e)  Should  Pledgor  fail to cure  any  default  within  three  (3)
            business days of receiving  written  notice of such default from the
            Secured  Party the  Secured  Party may remedy any default by Pledgor
            hereunder,  without waiving such default, and any monies expended in
            so doing shall be  chargeable  with interest to Pledgor and added to
            the Secured Obligations secured hereby;

- - --------------------------------------------------------------------------------
             FIRST AMENDED PLEDGE AND SECURITY AGREEMENT, PAGE 7
<PAGE>

            (f) The Secured Party may apply for a temporary  restraining  order,
            and/or an injunction  to restrain a breach or  threatened  breach of
            this Agreement by Pledgor;

            (g) Pledgor  agrees that the Secured  Party shall not be required to
            register or qualify any of the Collateral  under applicable state or
            federal securities laws in connection with any such sale if the sale
            is effected in a manner that  complies with all  applicable  federal
            and state securities laws or exemptions therefrom. The Secured Party
            shall be authorized at any such sale (if it deems it advisable to do
            so) to restrict the prospective bidders or purchasers to persons who
            will represent and agree that they are purchasing the Collateral for
            their  own  account  for  investment  and  not  with a  view  to the
            distribution or sale thereof.  In the event that any such Collateral
            is sold at private sale,  Pledgor agrees that if such  Collateral is
            sold for a price that the Secured Party in good faith believes to be
            reasonable under the circumstances then existing,  then (a) the sale
            shall be deemed to be commercially  reasonable in all respects,  (b)
            Pledgor  shall  not be  entitled  to a credit  against  the  Secured
            Obligations  in an amount in excess of the purchase  price,  and (c)
            the Secured Party shall not incur any liability or responsibility to
            Pledgor in connection  therewith,  notwithstanding  the  possibility
            that a  substantially  higher  price  might have been  realized at a
            public sale.  Pledgor  hereby waives any claims  against the Secured
            Party  arising  by  reason  of the fact  that the price at which the
            Collateral may have been sold at such private sale was less than the
            price  which  might have been  obtained at a public sale or was less
            than the Secured Obligations,  even if the Secured Party accepts the
            first offer  received and does not offer the Collateral to more than
            one offeree  (other than the Secured  Party or an  affiliate  of the
            Secured  Party),  unless such sale was not  commercially  reasonable
            under the circumstances;

            (h) To the  extent  notice of sale  shall be  required  by law,  the
            Secured  Party  shall  give the  Pledgor at least ten (10) days' (or
            such longer period as shall be specified by applicable  laws) notice
            of the time and place of any public sale or the time after which any
            private sale is to be made,  which Pledgor  agrees shall  constitute
            commercially reasonable notification.  At any such sale, the Secured
            Party, to the extent permitted by law, may bid (which bid may be, in
            whole  or  in  part,  in  the  form  of   cancellation   of  Secured
            Obligations)  for and purchase for the account of the Secured  Party
            the whole or any part of the Collateral. The Secured Party shall not
            be obligated to make any sale of Collateral  regardless of notice of
            sale having been given.  The Secured Party may adjourn any public or
            private sale from time to time by announcement at the time and place
            fixed therefor,  and such sale may, without further notice,  be made
            at the time and place to which it was so  adjourned.  If sale of all
            or any  part  of the  Collateral  is made on  credit  or for  future
            delivery,  the  Collateral  so sold may be  retained  by the Secured
            Party until the sale price is paid by the  purchaser  or  purchasers
            thereof, but the Secured Party shall not incur any liability in case
            any such  purchaser or purchasers  shall fail to take up and pay for
            the  Collateral  so sold  and,  in case of any  such  failure,  such
            Collateral  may be sold again upon like notice.  Pledgor agrees that
            any  sale  of the  Collateral  conducted  by the  Secured  Party  in
            accordance with the foregoing provisions of this Section 14(h) shall
            be deemed to be a  commercially  reasonable  sale under the  Uniform

- - --------------------------------------------------------------------------------
             FIRST AMENDED PLEDGE AND SECURITY AGREEMENT, PAGE 8
<PAGE>

            Commercial  Code as in  effect  in the  State of Texas  from time to
            time;

            (i) As an  alternative  to  exercising  the  power  of  sale  herein
            conferred  upon it, the Secured Party may proceed by a suit or suits
            at law or in equity to foreclose the security interest granted under
            this Agreement and to sell the Collateral,  or any portion  thereof,
            pursuant to a judgment  or decree of a court or courts of  competent
            jurisdiction;

            (j) Any cash held by the Secured  Party as  Collateral  and all cash
            proceeds  received by the  Secured  Party in respect of any sale of,
            collection  from, or other  realization  upon all or any part of the
            Collateral (i) prior to the occurrence of an Acceleration  shall, at
            the  option of the  Secured  Party,  be  applied  as is set forth in
            subparts  (x) and (y) of this  paragraph,  or be held by the Secured
            Party as collateral  for the Note, and (ii) following the occurrence
            of an  Acceleration  may be held by the Secured  Party as Collateral
            and/or then or at any time thereafter applied as follows: (x) first,
            to the  payment to the  Secured  Party of the costs and  expenses of
            retaking,  holding and preparing for sale of the  Collateral and any
            other fees, expenses,  claims, demands, losses,  judgments,  damages
            and liabilities arising out of or related to any Loan Document which
            are payable to the Secured Party,  including arising in the Note and
            this Agreement, and (y) second, to the Secured Party for application
            against or on account of all or any part of the Note; and

            (k) Any  surplus of such cash or cash  proceeds  held by the Secured
            Party and  remaining  after payment in full of all the Note shall be
            reassigned and redelivered as provided in Section 20 hereof.

      Section 15. Expenses.  The Secured Party shall be entitled to receive from
any proceeds of the Collateral,  the amount of any and all reasonable  expenses,
including,  in the event of default, the fees and expenses of its counsel and of
any experts and agents which the Secured Party may incur in connection  with (i)
the  administration  of this Agreement,  (ii) the custody or preservation of, or
the sale of,  collection from, or other realization upon, any of the Collateral,
(iii) the  exercise or  enforcement  of any of the rights of the  Secured  Party
hereunder,  or (iv) the  failure by any Pledgor to perform or observe any of the
provisions hereof.

      Section 16. Security  Interest  Absolute.  All rights of the Secured Party
hereunder,  the interest,  and all  obligations of Pledgor  hereunder,  shall be
absolute and unconditional irrespective of:

            (i) any lack of validity or  enforceability of the Loan Documents or
            the  Secured  Obligations  or  any  other  agreement  or  instrument
            relating to the Loan Documents or the Secured Obligations;

            (ii) any change in the time,  manner or place of  payment  of, or in
            any other term of, the Loan Documents or the Secured Obligations, or

- - --------------------------------------------------------------------------------
             FIRST AMENDED PLEDGE AND SECURITY AGREEMENT, PAGE 9
<PAGE>

            any  renewal  or  extension  of the Loan  Documents  or the  Secured
            Obligations  or any other  amendment  or waiver of or any consent to
            any  departure  from  this  Agreement  or  any  other  agreement  or
            instrument;

            (iii) any sale,  exchange,  release or  nonperfection  of any of the
            Collateral,  or any release of any guarantor or any person liable in
            any  manner  for  the   collection   of  the  Note  or  the  Secured
            Obligations,  or  any  amendment  or  waiver  of  or  consent  to or
            departure  from any  guaranty,  the Loan  Documents  or the  Secured
            Obligations; or

            (iv) any  other  circumstance  that  might  otherwise  constitute  a
            defense  available to, or a discharge of,  Pledgor in respect of any
            of the Loan Documents or the Secured Obligations.

      Section 17. Amendments and Waivers. The Loan Documents represent the final
agreement  agreed to by the parties.  No amendment or waiver of any provision of
the Loan  Documents,  and no consent by Secured  Party to any breach  thereof by
Pledgor shall in any event be effective  unless the same shall be in writing and
signed by the Secured Party,  Pledgor and, if appropriate,  any guarantor of any
Secured Obligation,  and then such waiver or consent shall be effective only for
the specific purpose for which given. No course of dealing between Pledgor,  any
guarantor of any Secured  Obligation  and Secured Party in exercising any rights
or  remedies in the Loan  Documents  shall  operate as a waiver or preclude  the
exercise of any other rights or remedies in the Loan Documents.  All such rights
and remedies shall continue unimpaired,  notwithstanding any delay, extension of
time, renewal, compromise or other indulgence granted with respect to any of the
Secured  Obligations.  Pledgor  hereby  waives  all  notice  of any such  delay,
extension of time, renewal,  compromise or indulgence,  and consents to be bound
thereby as fully and  effectually as if Pledgor  expressly had agreed thereto in
advance.  The  aforesaid  Note  may be  negotiated  by  Secured  Party,  without
releasing Pledgor or the Collateral.

      Section 18. Time is of the Essence; No Waiver:  Cumulative Remedies.  Time
and  exactitude of each of the terms,  obligations,  covenants and conditions of
this Agreement are hereby declared to be of the essence.  No failure on the part
of the Secured Party to exercise,  and no delay in exercising,  any right, power
or remedy  hereunder shall operate as a waiver thereof,  nor shall any single or
partial  exercise  of any such  right,  power or  remedy  by the  Secured  Party
preclude  any other or further  exercise  thereof or the  exercise  of any other
right,  power or remedy.  All  remedies  hereunder  are  cumulative  and are not
exclusive of any other remedies provided by law.

      Section 19. Binding Effect. This Agreement shall be binding upon and inure
to the  benefit of the parties  hereto and their  respective  heirs,  executors,
administrators,  successors  and  assigns.  The  Secured  Party may assign  this
Agreement,  and if assigned,  the assignee  shall be  entitled,  upon  notifying
Pledgor,  to the payment and  performance of all of the Secured  Obligations and
agreements of Pledgor hereunder and to all of the rights and remedies of Secured
Party hereunder,  and Pledgor will assert no claims or defenses Pledgor may have
against  Secured Party against the assignee.  The gender and number used in this
Agreement are used for reference  term only and shall apply with the same effect
whether the parties are masculine, feminine, neuter, singular or plural.

<PAGE>

      Section 20.  Termination.  This Agreement shall terminate upon the payment
in full of the Note and Secured Obligations.  Upon such termination, the Secured
Party shall reassign and redeliver (or cause to be reassigned  and  redelivered)
to appropriate  Pledgor, or to such person or persons as Pledgor shall designate
or to  whomever  may be  lawfully  entitled  to receive  such  surplus,  against
receipt,  such of the  Collateral  pledged by that Pledgor (if any) as shall not
have been sold or otherwise  applied by the Secured Party  pursuant to the terms
hereof  and  shall  still be held by it  hereunder,  together  with  appropriate
instruments of reassignment and release.  Any such reassignment shall be without
recourse upon or warranty by the Secured Party and at the expense of Pledgor.

      Section 21. Addresses for Notices. Any notice or communication to be given
or made hereunder shall be in writing  (including  facsimile  communication) and
may be given or made personally or by first class letter, telefax, courier telex
or tested telex, telegram or cable (confirmed, in the case of a telecopy, telex,
telegram or cable, by a letter  delivered  personally  within,  or dispatched by
first class mail within, twenty-four (24) hours of the dispatch of such telefax,
telex, telegram or cable) and shall be effective when actually received. For the
purposes hereof,  the address of the Pledgor shall be the address  maintained in
the records of the Secured Party (until  notice of a change  thereof is given as
provided in this Section 21), and the address of the Secured Party (until notice
of a change  thereof  is given  as  provided  in this  Section  21)  shall be as
follows:

                              Value Partners, Ltd.
                                2200 Ross Avenue

                              Dallas, Texas 75201.

      Section 22.  Continuing  Security  Interest;  Assignments.  This Agreement
shall  create a continuing  security  interest in the  Collateral  and shall (i)
remain in full force and effect until termination as provided in herein, (ii) be
binding upon Pledgor,  the Secured  Party and their  respective  successors  and
assigns,  and (iii)  inure,  together  with the rights,  powers and  remedies of
Pledgor and the Secured Party hereunder,  to the benefit of Pledgor, the Secured
Party and their respective successors,  transferees and assigns, as the case may
be.

      Section 23.  Governing Law. This Agreement and the rights and  obligations
of the  parties  hereto  shall be  governed  by and  construed  and  enforced in
accordance  with the laws of the State of Texas  (other  than  conflict  of laws
rules).

      Section  24.  Severability.  Wherever  possible,  each  provision  of this
Agreement  shall  be  interpreted  in such  manner  as to be  effective.  If any
provisions of this  Agreement or any lien,  security  interest or other right of
the  Secured  Party  hereunder   shall  be  held  to  be  invalid,   illegal  or
unenforceable   under   applicable   law,   such   invalidity,   illegality   or
unenforceability  shall  not  affect  any  other  provision  herein or any lien,
security interest or other right granted hereby.

      Section 25. Usury.  All agreements  between Pledgor and the Secured Party,
whether now  existing or  hereafter  arising  and whether  written or oral,  are

hereby  limited  so that in no  contingency,  whether  by  reason  of  demand or
acceleration of the Final Maturity Date, as that term is defined in the Note, or
otherwise,  shall the interest contracted for, charged, received, paid or agreed
to be paid to the Secured Party exceed the maximum amount  permissible under the
laws of the State of Texas  (hereinafter  the  "Applicable  Law").  If, from any
circumstance  whatsoever,  interest  would  otherwise  be payable to the Secured
Party in excess of the maximum amount  permissible under the Applicable Law, the
interest  payable to the Secured  Party  shall be reduced to the maximum  amount
permissible  under the Applicable Law, and if from any  circumstance the Secured
Party shall ever receive anything of value deemed interest by the Applicable Law
in excess of the maximum amount  permissible under the Applicable Law, an amount
equal  to the  excessive  interest  shall be  applied  to the  reduction  of the
principal hereof and not to the payment of interest, or if such excessive amount
of interest exceeds the unpaid balance of principal hereof, such excess shall be
refunded to the party making such  payment.  All  interest  paid or agreed to be
paid to the Secured Party shall, to the extent  permitted by the Applicable Law,
be  amortized,  prorated,  allocated  and  spread  throughout  the  full  period
(including  any renewal or extension)  until payment in full of the principal so
that the  interest  hereon for such full  period  shall not  exceed the  maximum
amount  permissible  under the  Applicable  Law.  The  Secured  Party  expressly
disavows  any intent to contract  for,  charge or receive  interest in an amount
which exceeds the maximum  amount  permissible  under the  Applicable  Law. This
paragraph shall control all agreements between Pledgor and the Secured Party.

      Section  26.  Multiple  Counterparts.  This  Agreement  may be executed in
separate or multiple  counterparts by the parties,  and all of such counterparts
shall be considered as one and the same instrument notwithstanding the fact that
various  counterparts are signed by only one or more of the parties,  and all of
such Agreements shall be deemed but one and the same Agreement.

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

     products,   customers,   processes,  and  services,  including  information
     relating to testing research,  development,  manufacturing,  marketing, and
     selling,  disclosed  to the  Consultant  or  otherwise  made  known  to the
     Consultant as a consequence  of or through the  Consultant's  engagement by
     the  Company  (including  information  originated  by  the  Consultant  and
     information  obtained by the  Conultant  during any previous  consulting or
     employment engagement or any previous relationship with the Company) in any
     technological  area  previously  developed  by the  Company  or  developed,
     engaged  in,  or  researched,  by  the  Company  during  the  term  of  the
     Consultant's  engagement,  including,  but not limited to,  trade  secrets,
     processes, products, formulae, apparatus,  techniques,  know-how, marketing
     plans,  data,  improvements,  strategies,  forecasts,  customer lists,  and

     competitors.

          (b)  The  Consultant  acknowledges  that  the  Company  has  exclusive
     property rights to all Confidential  Information and the Consultant  hereby
     assigns  all rights  that the  Consultant  might  otherwise  possess in any
     Confidential  Information  to  the  Company.  Except  as  required  in  the
     performance of the Consultant's duties to the Company,  the Consultant will
     not at any time  during or after the term of the  Consultant's  engagement,
     which term shall include any time in which the  Consultant  may be retained
     by the Company as a consultant,  directly or indirectly  use,  communicate,
     disclose, or disseminate any Confidential Information.

          (c) All documents,  records,  notebooks, notes, memoranda, and similar
     repositories of, or containing,  Confidential  Information made or compiled
     by the Consultant at any time or made available to the Consultant  prior to
     or during the term of Consultant's engagement by the Company, including any
     and all copies thereof, shall be the property of the Company, shall be held
     by the Consultant in trust solely for the benefit of the Company, and shall
     be delivered to the Company by the  Consultant  on the  termination  of the
     Consultant's engagement or at any other time on the request of the Company.

          (d) The  Consultant  will not assert any rights under any  inventions,
     copyrights,  discoveries,  concepts,  or ideas, or improvements thereof, or
     know-how related thereto, as having been made or acquired by the Consultant
     prior to the  Consultant's  being engaged by the Company or during the term
     of  the  Consultant's  engagement  if  based  on or  otherwise  related  to

     Information  pursuant to a valid order of any  governmental  or  regulatory
     authority, or pursuant to the order of any court or arbitor.

          (f) The  Consultant  agrees that since a violation of this paragraph 6
     would cause irreparable injury to the Comapny, and that there may not be an
     adequate  remedy at law for such  violation,  the  Company  shall  have the
     right, in addition to any other remedies  available at law or in equity, to
     enjoin the  Consultant in a court of equity for violating the provisions of
     this paragraph 6.

assume as a result of, or relative to, any allegation,  claim, civil or criminal
action,  proceeding,  charge,  or  prosecution,  which  may  be  alleged,  made,
instituted,  or maintained  against the  Consultant  or the Company,  jointly or
severally,  if (a) the  Consultant was made a party to any action arising out of
or based upon the Consultant's  rendering of services pursuant to this Agreement
and (b) the Consultant acted in good faith and in a manner  reasonably  believed
by the Consultant to be in or not opposed to the interests of the Company,  and,
with respect to any criminal  action or proceeding,  had no reasonable  cause to

reasonable  attorneys'  fees,  together  with  interest  thereon as  provided by
applicable law.

9 .  INDEPENDENT  CONTRACTOR  STATUS;  SERVICE ON THE BOARD OF DIRECTORS.  It is
expressly  understood  and agreed that this is a consulting  agreement  only and
does  not  constitute  an  employer-emloyee   relationship.   Accordingly,   the

independent  contractor  and that the Company shall have no right to control the
activities  of the  Consultant  other than during the express  period of time in
which the Consultant is performing services hereunder,  and that such control by

and not because of any presumed employee-employer  relationship.  The Consultant
shall have no  authority to bind the Company.  The parties  further  acknowledge
that the Consultant's services hereunder are not exclusive.

Consultant  shall be  compensated  for his  service as a Director of the Company
according to the usual and customary terms of compensation for a Director, which
Director's  compensation shall be in addition to his Monthly Consulting Fees and

     by any long-term disability program of the Company in effect at the time of
     such termination. The payment of the Accrued Benefits by the Company to the
     Executive shall be in addition to, and not in lieu of, any benefits payable
     by reason of the  Executive's  Disability to the extent  provided under any
     long-term  disability  program of the  Company in effect at the time of the

     terminate the Executive's  employment  hereunder  without cause at any time
     upon  notice  to the  other  party,  and  upon any  such  termination,  the
     Executive shall be entitled to receive his Accrued  Benefits.  In the event

            and the  determination  by the Board, in its sole  discretion,  that

                  (ii)  The   conviction   of  the  Executive  on  a  felony  or
            misdemeanor involving moral turpitude (as evidenced by a binding and
            final   judgment,   order,   or  decree  of  a  court  of  competent
            jurisdiction)  an the  determination  by  the  Board,  in  its  sole

            duties or responsibilities (unless significantly changed without the
            Executive's  consent)  and  after  notice  from the  Company  to the
            Executive,  the Executive's continuing refusal to perform his duties
            or  responsibilities  during the 48-hour period following the giving

            without the Executive's consent).

                  (v) In the event of termination for cause, as set forth above,
            the Executive will be entitled to receive his Accrued Benefits,  but
            will not be entitled to the Severance  Payment,  except as otherwise
            provided by Texas law.

     any  Business,  provided,  however,  that for  purposes of this  Subsection
     13(a), ownership of securities of not in excess of five percent (5%) of any
     class of securities of a public  company shall not be considered as owning,
     managing,  operating,  or controlling  any Business  except as specifically
     decribed below in this paragraph 13; or

          (b) Within any  jurisdiction or marketing area in which the Company or

     competitive with the Company's current business. The Executive

     the Company  when and if such a conflict of interest  could have a material
     adverse effect on the Company's operations or financial condition.

     or entity  which is an  international  facilities-based  telecommunications
     carrier  or  any of the  services  which  are  necessarily  provided  by an
     international facilities-based telecommunications carrier to its customers.

     14 . REMEDIES AND JURISDICTION.

          (a) The Executive hereby  acknowledges and agrees that a breach of the
     agreements contained in Section 13 of this Agreement will cause irreparable
     harm and  damage to the  Company,  that the remedy at law for the breach or
     threatened  breach  of the  agreements  set  forth  in  Section  13 of this
     Agreement will be  inadequate,  and that, in addition to all other remedies
     available to the Company for such breach or threatened  breach  (including,

     entitled to injunctive  relief for any breach or  threatened  breach of the

     (including such procedures  governing  selection of the specific arbitrator
     or arbitrators),  unless the parties otherwise agree. The Company shall pay
     the  costs  of  any  such  arbitration.  The  award  by the  arbitrator  or

     accordance  with applicable law in any state or federal court having proper
     jurisdiction.

     15 . INDEMNIFICATION.

     The Company  agrees to indemnify and hold the  Executive  harmless from and
against any and all losses,  liabilities,  or costs (including,  but not limited
to,  reasonable  attorney's  fees),  which the Executive may sustain,  incur, or
assume as a result of, or relative to, any allegation,  claim, civil or criminal
action,  proceeding,  charge,  or  prosecution,  which  may  be  alleged,  made,
instituted,  or  maintained  against the  Executive or the  Company,  jointly or
severally,  arising  out of or based upon the  Executive's  employment  with the
Company,  to the fullest extent  permitted by applicable law including,  but not
limited to, any injury to  person(s) or damage to property or business by reason

or willful misconduct by the Executive.

of this Lease and if such nonperformance shall continue for a period of ten (10)
days after notice thereof by Landlord to Tenant, time being of the essence.

                                EFFECT OF DEFAULT

      18. In the event of any  default or breach  hereunder,  in addition to any
other  right or  remedy  available  to  landlord,  either  at law or in  equity,
Landlord may exert any one or more of the following rights:

      (a) Landlord may re-enter the Premises immediately and remove the property
and personnel of Tenant,  and shall have the right,  but not the obligation,  to
store such property in a public warehouse or at a place selected by Landlord, at
the risk and expense of Tenant.

      (b)  Landlord  may retake the  Premises  and may  terminate  this Lease by
giving written notice of termination to Tenant. Without such notice,  Landlord's
retaking will not terminate the Lease. On termination, Landlord may recover from
Tenant all damages proximately resulting from the breach,  including the cost of
recovering the Premises and the difference  between the rent due for the balance
of the  Lease  term,  as  though  the  Lease  had not been  terminated,  and the
reasonable  rental value of the  Premises,  which sum shall be  immediately  due
Landlord from Tenant.

      (c)  Landlord  may relet the  Premises  or any part  thereof  for any term
without terminating this Lease, at such rent and on such terms as it may choose.
Landlord  may make  alterations  and  repairs to the  Premises.  In  addition to
Tenant's liability to Landlord for breach of this lease,  Tenant shall be liable
for all expenses of the reletting for any  alterations and repairs made, and for
the rent due for the balance of the Lease term,  which sums shall be immediately
due  Landlord  from Tenant.  The amount due Landlord  will be reduced by the net
rent received by Landlord during the remaining term of this Lease from reletting

                                       7
<PAGE>

the Premises or any part  thereof.  If during the  remaining  term of this Lease
Landlord  receives more than the amount due Landlord  under this  sub-paragraph,
the Landlord shall pay such excess to Tenant,  but only to the extent Tenant has
actually made payment pursuant to this sub-paragraph.

                                SURRENDER -- HOLDING OVER

      19. Tenant shall, upon termination of this Lease, whether by lapse of time
or  otherwise,  peaceably and promptly  surrender  the Premises to landlord.  If
Tenant  remains in possession  after the  termination  of this Lease,  without a
written lease duly executed by the parties, Tenant shall be deemed a trespasser.
If Tenant pays and Landlord accepts, rent for a period after termination of this
Lease, Tenant shall be deemed to be occupying the Premises only as a tenant from
month to month,  subject to all the terms,  conditions,  and  agreements of this
Lease, except that the rent shall be two times the monthly rent specified in the
lease immediately before termination.

                          SUBORDINATION AND ATTORNMENT

      20.  Landlord  reserves the right to place liens and  encumbrances  on the
Premises superior in lien and effect to this Lease. This Lease and all rights of
Tenant hereunder shall at the option of Landlord,  be subject and subordinate to
any liens  and  encumbrances  now or  hereafter  imposed  by  Landlord  upon the
Premises or the  Building  or any part  thereof,  and Tenant  agrees to execute,
acknowledge,  and deliver to Landlord, upon request any and all instruments that
may be necessary or proper to  subordinate  this Lease and all rights  herein to
any such lien or encumbrance as may be required by Landlord.

      In the  event any  proceedings  are  brought  for the  foreclosure  of any
mortgage on the Premises, Tenant will attorn to the purchaser at the foreclosure
sale and  recognize  such  purchaser  as the  Landlord  under  this  Lease.  The
purchase,  by virtue of such  foreclosure,  shall be deemed to have  assumed  as
substitute Landlord,  the terms and conditions of this Lease until the resale or
other disposition of its interest. Such assumption, however, shall not be deemed
an  acknowledgment  by the purchaser of the validity of any then existing claims
of Tenant against the prior Landlord.

      Tenant  agrees to execute and deliver  such further  assurances  and other
documents,  including a new lease upon the same terms and  conditions  contained
herein,  confirming  the foregoing,  as such  purchaser may reasonably  request.
Tenant waives any right or election to terminate  this Lease because of any such
foreclosure proceedings.

                                     NOTICES

      21. Any notice of demands to be given  hereunder shall be given in writing
and sent by registered or certified mail to Landlord at: 7300 Woolworth  Avenue,
Omaha,  Nebraska 68124, and to Tenant at 9601 Katy Freeway,  Suite 200, Houston,
Texas  77024 and  WorldPort  Communications,  Inc.  or at such other  address as
either party may from time to time designate in writing.  Each such notice shall
be deemed to have been  given at the time it shall be  personally  delivered  to
such  address or deposited  in the United  States mail in the manner  prescribed
herein.

                                       8

                               RIGHT TO TERMINATE

      22.  Landlord  shall have the right to terminate  this Lease at the end of
any  calendar  month by giving  the  Tenant  written  notice at least six months
before the date of the termination of Landlord's intention to remodel, remove or
demolish  the  Building,  or to  sell,  or  make a  ground  lease  of  the  land
thereunder.

                                  MISCELLANEOUS

      23. (a)  Binding on Assigns.  All  terms, conditions,  and  agreements  of
this Lease shall be binding upon, apply, and inure to the benefit of the parties
hereto and their respective heirs, representatives, successors, and assigns.

      (b) Amendment in Writing. This Lease contains the entire agreement between
the parties and may be amended only by subsequent written agreement.

      (c)  Waiver  - None.  The  failure  of  Landlord  to  insist  upon  strict
performance  of any of the terms,  conditions and agreements of this Lease shall
not be deemed a waiver of any of its rights or remedies  hereunder and shall not
be deemed a waiver of any  subsequent  breach or default  of any of such  terms,
conditions,  and agreements. The doing of anything by Landlord which Landlord is
not obligated to do hereunder shall not impose any future obligation on Landlord
nor otherwise amend any provision of this Lease.

      (d) No Surrender. No surrender of the Premises by Tenant shall be effected
by  Landlord's  acceptance  of the  keys  to the  Premises  or of the  rent  due
hereunder,  or  by  any  other  means  whatsoever,  without  Landlord's  written
acknowledgment that such acceptance constitutes a surrender.

      (e) Captions. The captions of the various paragraphs in this Lease are for
convenience only and do not define, limit, describe, or construe the contents of
such paragraphs.

      (f) Brokers. Tenant hereby warrants that no real estate broker has or will
represent it in this transaction and that no finder's fees have been earned by a
third party.

      (g) Applicable  Law.  This Lease shall be  governed  by and  construed  in
accordance with the laws of the State of Nebraska.

                                OTHER PROVISIONS

      24. All of Tenant's  computers  and  switching  equipment in the Switching
Room will be served by dedicated electrical lines,  installed by and metered and
billed to the Tenant.

      Until this Lease is executed on behalf of all parties hereto,  it shall be
construed as an offer to lease of Tenant to Landlord.
