Item 5.  Other Events

         TeleHub   Communications   Corporation,   a  Nevada   corporation  (the
"Company"),  has agreed to enter into a strategic  joint venture with  Newbridge
Networks Corporation, a Canadian corporation  ("Newbridge"),  for the purpose of
developing  and  marketing  the  Company's   Virtual  Access  Service   Platform
("VASP(TM)") call server technology (the "Proposed Transaction"). Newbridge is a
leading  Asynchronous  Transfer Mode ("ATM")  switch  manufacturer  (a principal
market for the VASP(TM)  technology),  with  approximately  25% of the worldwide
installed  ATM-switch  base.  The  Company  has  decided to enter into the Joint
Venture for the following principal reasons:

(i)   The Joint  Venture  will enable the Company to partner  with a leading ATM
      switch manufacturer with significantly greater financial, sales, marketing
      and product support  infrastructure,  and existing strategic relationships
      than the Company.  In addition,  Newbridge's  engineering  resources  will
      allow  an  accelerated  and  more  robust  roll-out  of  planned  VASP(TM)
      enhancements.  The Company and  Newbridge  believe that together they will
      capture a  significant  portion of the emerging  market to replace  legacy
      circuit switches with multiservice packet switches. Leveraging Newbridge's
      resources,  the  Company  believes  that it can more  rapidly  utilize its
      first-to-market advantage and gain increased market share.

(ii)  The Joint Venture will provide  substantial  working capital to accelerate
      the  rollout  of  planned   VASP(TM)   enhancements   and   capitalize  on
      first-to-market advantages.

(iii) The Joint Venture will provide the Company with an additional  $30 million
      of working  capital for continued  expansion of its ATM network,  which is
      presently  maintained  and  operated  by  the  Company's  TeleHub  Network
      Services Corporation subsidiary.

         In the Joint Venture, the Company and TeleHub Technologies Corporation,
a Nevada  corporation and a wholly-owned  subsidiary of the Company ("TTC") will
transfer their VASP(TM)- related assets to TeraBridge Technologies  Corporation,
a  newly-formed  Nevada  corporation  ("TeraBridge").  The Company  will receive
506,667  TeraBridge  common  shares  ("TeraBridge  Shares"),  TTC  will  receive
16,200,000  TeraBridge Shares and TeraBridge will assume $22 million of TTC debt
owed to  Company  for  VASP(TM)  development  costs.  After  completion  of this
transfer,  Newbridge  will  purchase  19% of  TeraBridge's  common stock for $60
million (the "Newbridge  Initial  Investment") from TeraBridge and Company:  $52
million to  TeraBridge  for 3,293,333  newly-issued  TeraBridge  Shares;  and $8
million  to  Company  for  506,667  TeraBridge  Shares.  Both  the  Company  and
TeraBridge  (after  repaying  the $22  million  debt to  Company)  will  use the
proceeds received from Newbridge for their working capital needs. Closing of the
Joint  Venture is subject to  customary  conditions,  especially  obtaining  all
regulatory  approvals and  receiving  the consent of the Company's  bondholders.
Assuming all conditions are satisfied,  the Company  anticipates  that the Joint
Venture will commence in May 1999.

         During the year following commencement of the Joint Venture,  Newbridge
will have an option to increase  its  ownership of  TeraBridge  up to 50% for an
additional $10 million.  This additional $10 million investment will be effected
by the issuance of new  TeraBridge  Shares to Newbridge and the proceeds will be
retained by TeraBridge for working capital and general corporate purposes.

       Newbridge Networks and TeleHub Technologies Joint Venture Delivers
                            Converged Networks Today

            Newbridge Invests US $60 million; Company Leads Industry
                         with Dynamic Services Platform

KANATA, Ontario and GURNEE, Illinois, April 6, 1999 -- Newbridge Networks (NYSE:
NN; TSE:  NNC),  a leader in  multiservice,  multi-access  wide area  networking
(WAN), and TeleHub Technologies  Corporation (TTC),  specialists in call control
software, today announced the formation of a joint venture to lead the market in
the delivery of a family of  intelligent  call and service  control  products to
address  and  accelerate  the  replacement  of  narrowband  toll-tandem  circuit
switching with next generation broadband networks.

"We are focusing the energies of an aggressive  new company on  delivering  this
first-to-market  solution without the constraints of an installed base of legacy
narrowband  switches," said Alan Lutz,  president and chief  operating  officer,
Newbridge  Networks.  "Our unique approach to address this important  market and
significant  revenue  opportunity  signals  a  true  inflection  point  for  the
industry."

The company  will  leverage  the  Newbridge(R)  position as a leading  vendor of
multiservice, multi-access WAN solutions and TeleHub's innovative Virtual Access
Services  Platform(TM)  (VASP(TM))  software suite. The joint product  portfolio
addresses the needs of both established and next generation  service  providers.
It accelerates the convergence of voice and data services over an integrated and
flexible broadband network  architecture,  while protecting a service provider's
investment  in  legacy  narrowband  circuit  switches  by  enabling  a  graceful
evolution from this older technology.

"We are extremely  pleased to enter into this important  venture with Newbridge,
which will have  far-reaching  impact on the  industry,"  remarked  Don  Sledge,
president and chief  executive  officer of TeleHub  Communications  Corporation.
"Newbridge  broadband  WAN switches and TeleHub VASP program logic are currently
processing  more than 25 million  minutes of voice traffic daily in our network.
Combined,  our solution  meets current voice and bandwidth  market needs,  while
offering a cost  effective  migration  path for  carriers  to  deliver  multiple
services over a single network infrastructure."

"The Newbridge-TeleHub solution for the new public network is an industry first.
Equally  important,  it is available  today," said Brian Jervis,  executive vice
president,  Switching Products Group,  Newbridge  Networks,  and chairman of the
joint venture. "Carriers throughout the world are moving to cap their investment
in Class 4 narrowband  circuit  switches.  Our solution delivers highly scalable
and flexible broadband networks for incumbent and alternate carriers."

Newbridge Networks and TeleHub Technologies Joint Venture              page 2
Delivers Converged Networks Today 

                        
TeleHub's VASP technology solution has been deployed in a next generation public
carrier  network for more than one year.  VASP will now control and manage voice
communications,   including  call  processing  and  Signaling   System  7  (SS7)
interworking,  across the Newbridge  multiservice,  multi-access platform.  This
joint  architecture  moves call processing  functionality  out of the relatively
rigid and inflexible  architecture of the traditional  narrowband central office
switches.  This capability enables the service providers to effectively overcome
the constraints of the existing public switched  telephone network (PSTN) tandem
switching infrastructure and integrate into on-demand voice, data and multimedia
networks.

"Working with Newbridge,  we are in a position to bring the full benefits of the
next generation  network to carriers.  Our solution  provides  carriers with the
ability to offer specialized voice and data services that complement traditional
telephony," said John Strand,  president of TeleHub Technologies Corporation and
president and chief operating officer of the joint venture.

"Large established service providers require a highly scalable, flexible network
architecture they can depend on to provide a wide variety of advanced services,"
said  analyst,  of  analyst  company.  "Alternate  service  providers  require a
cost-effective  solution to address their value-added service requirements.  The
Newbridge-TeleHub architecture is perfectly suited to both environments."

Newbridge  and  TeleHub  will  co-own  the joint  company,  which  will have its
headquarters  in Gurnee,  Illinois.  The  management  will  report to a board of
directors  equally  comprised of Newbridge and TeleHub  executives.  The initial
staff will include more than 130 personnel from the parent companies.

Newbridge  Networks  designs,  manufactures,  markets  and  services  networking
solutions to organizations in more than 100 countries. The Company leverages its
relationship  with a  growing  family  of  Newbridge  Affiliate  companies,  new
ventures and strategic  alliances  with Siemens and 3Com  Corporation to deliver
seamless,  end-to-end  solutions.  Newbridge  customers  include the world's 300
largest  telecommunications service providers and more than 10,000 corporations,
government  organizations and other  institutions.  Founded in 1986, the Company
employs  more than 6,000  people on six  continents.  News and  information  are
available at http://www.newbridge.com.

Located  just  outside  of  Chicago  in Gurnee  Illinois,  TeleHub  Technologies
Corporation  is  a  software  development  and  networking   technology  company
dedicated to providing cost effective,  intelligent networking solutions for the
carrier marketplace. More information is available at http://www.telehub.com.

                            ORGANIZATIONAL AGREEMENT

                  This Organizational Agreement (this "Agreement") dated  as  of
March  31,  1999  is  made  by  and  among  Newbridge  Networks  Corporation,  a
corporation   organized  under  the  laws  of  Canada   ("Newbridge"),   TeleHub
Communications  Corporation, a corporation organized under the laws of the State
of  Nevada,  one of  the  states  of  the  United  States  ("TeleHub"),  TeleHub
Technologies Corporation, a corporation organized under the laws of the State of
Nevada ("TTC") and Newco Corporation,  a corporation organized under the laws of
the State of Nevada and whose name will be changed  pursuant  to this  Agreement
(the "Company").

                                    RECITALS:

A.                    Newbridge  and  TeleHub  wish  to  form a new  venture  to
                      further  develop  the  Virtual  Access  Services  Platform
                      ("VASP(TM)")  technology  and  related  products  that are
                      essential   to   world-wide,   end-to-end,    service-rich
                      communications, as more fully described in Schedule 1 (the
                      "Business") and expand the market for the Business.

B.                    The  goal  of the  new  venture  will  be to  establish  a
                      successful,   highly   profitable   market   position  for
                      VASP(TM),   specifically   addressing   narrowband  switch
                      replacement,  addressing  the needs of incumbent  carriers
                      and alternate carriers,  in North America  originally.  In
                      doing so, the new venture will meet the needs of Newbridge
                      and TeleHub,  by  delivering a best of breed  product that
                      allows the users of the technology  competitive  advantage
                      in these markets.

C.                    The new venture will  ultimately be implemented  through a
                      new venture owned by TeleHub and Newbridge.  As one of the
                      first steps in organizing such new venture,  Newbridge and
                      TeleHub  shall  select  a new name  for the  Company,  and
                      TeleHub  will form the  Company  within 10 days  after the
                      date  hereof.   Newbridge   will  invest  in  the  Company
                      according to the terms of this Agreement.

D.                    TeleHub,  TTC and Newbridge wish the Company to operate as
                      a  new  venture  with  the  two  principal   shareholders,
                      Newbridge  and TTC,  operating in a spirit of  cooperation
                      and  collaboration  to  address  the  emerging  narrowband
                      switch replacement and data services markets and to grow a
                      profitable venture which leads these markets.

                                   AGREEMENTS

                  In  consideration  of the recitals and respective  agreements,
covenants,  representations  and warranties  contained herein and other good and
valuable  consideration,  the  receipt  and  sufficiency  of  which  are  hereby
acknowledged, the parties hereto agree as follows:

                           (c)  (i)  Each   Plan  has   been   established   and
         administered in accordance  with its terms,  and in compliance with the
         applicable  provisions of ERISA,  the Internal Revenue Code of 1986, as
         amended ("Code") and other applicable laws, rules and regulations;

                            (ii) Each Plan  which is  intended  to be  qualified
         within  the  meaning of Code  Section  401(a) is so  qualified  and has
         received a favorable  determination  letter as to its qualification and
         nothing has  occurred,  whether by action or failure to act, that could
         reasonably be expected to cause the loss of such qualification;

                           (iii) With respect to any Plan, no actions,  suits or
         claims (other than routine claims for benefits in the ordinary  course)
         are pending or, threatened,  and, no facts or circumstances exist which
         could give rise to any such actions, suits, or claims;

                           (iv) No event has occurred  and no  condition  exists
         that would  subject  TeleHub,  the Company or TTC, or any member of its
         "Controlled  Group" (defined as any organization which is a member of a
         controlled group of  organizations  within the meaning of Code Sections
         414(b),  (c),  (m) or (o) that  includes  TeleHub,  the  Company or TTC
         respectively),  to any tax,  fine,  lien,  penalty  or other  liability
         imposed  by  ERISA,  the  Code or  other  applicable  laws,  rules  and
         regulations;

                           (v) For each Plan with  respect  to which a Form 5500
         has been filed,  no material  change has  occurred  with respect to the
         matters covered by the most recent Form since the date thereof; and

                           (vi) No  "reportable  event" (as such term is defined
         in ERISA  Section  4043),  "prohibited  transaction"  (as such  term is
         defined in ERISA  Section 406 and Code  Section  4975) or  "accumulated
         funding  deficiency"  (as such term is defined in ERISA Section 302 and
         Code Section 412 (whether or not waived)) has occurred  with respect to
         any Plan.

                  (d)  With  respect  to  each  of  the  Plans  that  is  not  a
multiemployer  plan  within the  meaning of section  4001(a)(3)  of ERISA but is
subject to Title IV of ERISA,  as of the Closing  Date,  the assets of each such
Plan are at least  equal in value to the present  value of the accrued  benefits
(vested and  unvested) of the  participants  in such Plan on a  termination  and
projected  benefit   obligation  basis,  based  on  the  actuarial  methods  and
assumptions indicated in the most recent actuarial valuation reports.

                  (e) Neither  TeleHub,  the Company nor TTC, nor any Controlled
Group member,  is, nor has ever been, a party to any multiemployer  plan (within
the meaning of ERISA Section 4001(a)(3).





                                       22
<PAGE>

                  (f) No Plan  exists  that could  result in the  payment to any
person or former  employee of TeleHub,  the Company or TTC of any money or other
property or accelerate or provide any other rights or benefits to any present or
former employee of TeleHub,  the Company or TTC as a result of the  transactions
contemplated  by this  Agreement  or the Other  Agreements,  whether or not such
payment would constitute a parachute  payment within the meaning of Code Section
280G.

                  (g) TeleHub,  the  Company,  TTC,  and each  Controlled  Group
member is in compliance with Section 4980B of the Code  (so-called  "COBRA") and
all other laws which  require  the  continuation  of benefit  coverage  upon the
happening of certain events, such as the termination of employment.

                  4.19 Tax  Matters.  All Tax  Returns  required  to be filed by
either TeleHub,  the Company or TTC or any of their  Affiliates on or before the
Closing Date with respect to its  activities,  properties or employees have been
or shall be timely  filed and all Taxes which are due or which may be claimed to
be due with respect to its  activities,  properties  or  employees  have been or
shall be timely paid or accrued  within the  prescribed  period,  including  any
extension thereof. All such Tax Returns are complete and accurate.  There are no
liens due and payable. All Taxes required to be withheld by TeleHub, the Company
or TTC with  respect  to its  activities,  properties  or  employees  have  been
withheld and paid over to the appropriate Tax authority.  Neither  TeleHub,  the
Company nor TTC is a party to and has not  received  any notice with  respect to
any proposed or pending action by any  governmental  authority for assessment or
collection of Taxes with respect to its activities, properties or employees, nor
is TeleHub,  the Company or TTC a party to any dispute or threatened  dispute in
which action or dispute an adverse determination reasonably could be expected to
result in a foreclosure of the Purchased Assets and no such claim for assessment
or collection of Taxes has been made upon TeleHub,  the Company or TTC.  Neither
TeleHub, the Company nor TTC is a "foreign person" within the meaning of section
1445 of the Code, and, if requested,  each of TeleHub,  the Company and TTC will
furnish the other with an affidavit that satisfies the  requirements  of section
1445(b)(2) of the Code. None of the Purchased Assets are tax exempt use property
under section 168(h) of the Code. None of the Purchased Assets are property that
TeleHub,  the  Company or TTC are  required to treat as being owned by any other
Person pursuant to the safe harbor lease  provision of former section  168(f)(8)
of the Code. No portion of the cost of any of the Purchased  Assets was financed
directly  or  indirectly  from the  proceeds  of any tax  exempt  state or local
government obligation described in section 103 of the Code. Neither the Code nor
any other  provision  of law  requires  Newbridge to withhold any portion of the
investment described in Section 1.4. The Business,  TeleHub, the Company and TTC
are not a party to any joint  venture,  partnership  or other  arrangement  that
could be treated as a partnership for Tax purposes. Neither TeleHub, the Company
nor TTC has agreed to and is not required to make any  adjustment by reason of a
change in  accounting  methods  that  affects any taxable  year ending after the
Closing Date. There is no contract,  agreement, plan or arrangement covering any
employee or former employee of TeleHub, the Company or TTC that, individually or
collectively,  could give rise to the  payment by the Company of any amount that
would not be deductible  by reason of section 280G of the Code.  For purposes of

omit to state any material fact necessary in order to make the  statements  made

misleading.

                  4.22  Employee and  Consulting  Agreements  and  Arrangements.

the  Company  is party;  and (ii) all  incentive  compensation  and bonus  (with
respect to the Business and the Purchased  Assets) (based on sales or otherwise)
arrangements,  whether written or oral, by which TeleHub or TTC (with respect to

                  4.23  Absence  of  Undisclosed  Liabilities.  Neither  TeleHub
(arising out of or relating to the Business or the Purchased Assets) nor TTC nor
the Company has any  liabilities or obligations of any nature,  whether known or

                  As of the date  hereof and as of the Closing  Date,  Newbridge
warrants and represents to TeleHub, TTC and to the Company (which warranties and
representations  shall  survive the  Closing  regardless  of what  examinations,

organized and validly existing under the laws of Canada. Schedule 5.1 sets forth
the  states  in  which  Newbridge  is  qualified  to do  business  as a  foreign
corporation  and  Newbridge  is not required to be qualified to do business as a

adverse effect on the operations or the financial condition of Newbridge; and

                  (b) Newbridge has full corporate  power and authority to carry
on its business and to own or lease and to operate its  properties as and in the

right and power to execute  and  deliver  this  Agreement  and each of the Other

<PAGE>

to  which  it is a party  will  have  been,  duly  authorized  by all  requisite
corporate action of Newbridge.

                  (c) This  Agreement  is, and on the  Closing  Date each of the
Other Agreements to which Newbridge is a party will be, legal, valid and binding
obligations  of  Newbridge,  enforceable  against  it  in  accordance  with  its
respective  terms,  except as such  enforcement  may be limited  by  bankruptcy,
insolvency,   reorganization,   moratorium  or  other  similar  laws   affecting
enforcement of creditors'  rights generally and by general  principles of equity
(whether applied in a proceeding at law or in equity).

                  5.3  No  Violations.   Neither  the  execution,   delivery  or
performance of this  Agreement or the Other  Agreements by Newbridge to which it
is a party, nor the consummation of the other transactions  contemplated by this
Agreement,  does or will,  after the giving of notice,  or the lapse of time, or
otherwise:  (a) conflict  with,  result in a breach of, or  constitute a default
under, the Certificate of Incorporation or Bylaws of Newbridge,  or any federal,
foreign,  state or local law,  statute,  ordinance,  rule or regulation,  or any
court or administrative  order or process, or any material contract,  agreement,
commitment or plan to which Newbridge is a party or by which Newbridge or any of
its rights,  properties  or assets is subject or is bound;  or (b) result in the
creation of any mortgage,  pledge,  lien,  claim,  charge,  encumbrance or other
adverse interest upon any material right, property or asset of Newbridge.

                  5.4 Brokers.  Neither this Agreement nor any other transaction
contemplated by this Agreement was induced or procured through any person, firm,
corporation or other entity acting on behalf of, or  representing,  Newbridge or
any of its members as broker, finder, investment banker, financial advisor or in
any similar capacity.

hereto, the contents of which schedule have been previously  provided to TeleHub
and TTC, there are no actions, suits, proceedings or investigations,  commenced,
contemplated or threatened against or affecting Newbridge,  at law or in equity,

registration  afforded  by Rule 144 (the  provisions  of which are known to such

the Securities Act depends upon the  satisfaction  of various  conditions,  that
such exemption is currently not available and that, if applicable,  Rule 144 may
in many instances afford the basis for sales only in limited amounts.

severally  agree to defend,  indemnify  and hold the Company and  Newbridge  and

Agreements   by  TeleHub,   the   Company  or  TTC;   (b)  any   inaccuracy   or
misrepresentation  in or  breach  of  any of  the  warranties,  representations,
covenants or agreements made by TeleHub, the Company or TTC in this Agreement or

                                       36
<PAGE>


the  Schedules,  Financial  Statements,  or  any  other  certificate,  document,
instrument or affidavit  furnished by TeleHub,  the Company or TTC in accordance
with the provisions of this Agreement or the Other  Agreements;  (d) any and all
claims, debts, liabilities,  taxes and other obligations of TeleHub, the Company
or TTC, whether accrued, absolute, contingent or otherwise, not expressly agreed
to be assumed or  undertaken by the Company  pursuant to Section  1.2(a) of this
Agreement;  (e) any occurrence,  act or omission of any  stockholder,  director,

                  10.2 Newbridge  Indemnification.  Newbridge  agrees to defend,
indemnify and hold the Company,  TeleHub and TTC and their respective successors
and assigns harmless against any loss, damage or expense  (including  reasonable
attorneys'  fees),  which may arise out of or be in respect of (a) any breach or
violation   of   this   Agreement   by   Newbridge,   (b)  any   inaccuracy   or
misrepresentation  in or  breach  of  any of  the  warranties,  representations,
covenants or  agreements  made by  Newbridge  in this  Agreement or in the Other
Agreements or in Schedules  prepared by Newbridge to the  Agreement,  or (c) any
inaccuracy or  misrepresentation  in any  certificate,  document,  instrument or
affidavit  furnished by  Newbridge in  accordance  with the  provisions  of this
Agreement.

                  10.3 Indemnification Notice. Promptly upon obtaining knowledge
of any claim,  event,  statement  of facts or demand which has given rise to, or
could reasonably give rise to, a claim for indemnification  hereunder, any party
seeking indemnification under this Article X (an "Indemnified Party") shall give
written  notice of such  claim or demand  ("Notice  of Claim") to the party from
which  indemnification  is sought (an "Indemnifying  Party"),  setting forth the
amount of the claim.  The  Indemnified  Party shall furnish to the  Indemnifying
Party,  in reasonable  detail,  such  information as it may have with respect to
such indemnification claim (including copies of any summons,  complaint or other
pleading  which  may have  been  served  on it and any  written  claim,  demand,
invoice, billing or other document evidencing or asserting the same). No failure
or delay by the  Indemnified  Party in the  performance  of the foregoing  shall
reduce or otherwise affect the obligation of any Indemnifying Party to indemnify
and hold the Indemnified Party harmless,  except to the extent that such failure
or delay shall have materially and adversely  affected the Indemnifying  Party's
ability to defend against, settle or satisfy any liability,  damage, loss, claim
or  demand  for which  the  Indemnified  Party is  entitled  to  indemnification
hereunder.

                  10.4 Indemnification Procedure. (a) If the claim or demand set
forth in the Notice of Claim given by the Indemnified  Party pursuant to Section
10.3 of this  Agreement  is a claim or demand  asserted  by a third  party,  the
Indemnifying  Party shall have fifteen (15) days after the Date of the Notice of
Claim (as that term is hereinafter  defined) to notify the Indemnified  Party in





                                       37
<PAGE>

writing of its  election to defend such third party claim or demand on behalf of
the  Indemnified  Party. If the  Indemnifying  Party elects to defend such third
party  claim or  demand,  the  Indemnified  Party  shall make  available  to the
Indemnifying  Party and its agents and  representatives  all  records  and other
materials which are reasonably required in the defense of such third party claim
or demand and shall otherwise  cooperate with, and assist the Indemnifying Party
in the  defense  of,  such  third  party  claim  or  demand,  and so long as the
Indemnifying  Party is defending such third party claim or demand in good faith,
the Indemnified Party shall not pay, settle or compromise such third party claim
or demand. If the Indemnifying  Party elects to defend such third party claim or
demand, the Indemnified Party shall have the right to participate in the defense
of such third party claim or demand,  at its own  expense.  If the  Indemnifying
Party does not elect to defend  such third  party  claim or demand,  or does not
defend such third party claim in good faith,  the  Indemnified  Party shall have
the right,  in addition to any other right or remedy it may have  hereunder,  at
the Indemnifying  Party's  expense,  to defend such third party claim or demand;
provided,  however, that (i) the Indemnified Party shall not have any obligation
to  participate  in the  defense  of, or defend,  any such third  party claim or
demand; and (ii) the Indemnified  Party's defense of or its participation in the
defense of any such third party claim or demand shall not in any way diminish or
lessen  the  obligations  of the  Indemnifying  Party  under the  agreements  of
indemnification set forth in this Article X.

                  (b) Except  for third  party  claims  being  defended  in good
faith,  the Indemnifying  Party shall satisfy its obligations  hereunder in cash
within thirty (30) days after the Date of Notice of Claim.

                  (c) The term  "Date of the  Notice  of  Claim" as used in this
Article X shall mean the date the Notice of Claim is deemed  delivered  pursuant
to Section 12.10 hereof.

                  10.5  Limitations  on  Indemnity.  In the  absence  of  fraud,
TeleHub's obligation to indemnify the Company and Newbridge and their respective
successors and assigns for any breach of, or any inaccuracy or misrepresentation
in, any  representation  and warranty set forth in Article IV hereof,  shall not
exceed Ten Million  Dollars  ($10,000,000)  in the aggregate.  In the absence of
fraud,  Newbridge's  obligation  to indemnify  the Company,  TTC and TeleHub and
their respective  successors and assigns for any breach of, or any inaccuracy or
misrepresentation  in, any  representation  and  warranty set forth in Article V
hereof, shall not exceed Ten Million Dollars ($10,000,000) in the aggregate.

less favorable than the employee benefits offered by TTC as of the Closing Date,
to such employees.

                  11.2 Benefit  Plans.  Effective  upon  Closing,  TeleHub shall
consent to the participation of the Company as a "participating employer" in all
Plans  offered to employees of TeleHub.  Each former  employee of TeleHub who is
employed by the Company  immediately after the Closing and who was a participant
in a Plan  immediately  before the Closing shall continue to participate in such
Plan after the Closing,  subject to the terms of such Plan. The parties agree to
furnish all  information  and execute all  documents to the extent  necessary to
effect the terms of this Section 11.2.


                                   ARTICLE XII

with the Other  Agreements  contain  the entire  agreement  between  the parties
hereto with respect to the transactions  contemplated  hereunder,  and supersede
all negotiations,  representations,  warranties,  commitments, offers, contracts
and  writings  prior  to the date  hereof.  No  waiver  and no  modification  or
amendment  of  any  provision  of  this  Agreement  shall  be  effective  unless
specifically made in writing and duly signed by the party to be bound thereby.

                  12.3  Counterparts.  This  Agreement may be executed in one or
more counterparts,  each of which shall be deemed an original, but all of which,
together, shall constitute one and the same instrument.

                  12.4 Assignment, Successors and Assigns. The respective rights
and obligations of the parties hereto shall not be assignable  without the prior
written  consent of the other  parties;  provided,  however,  that Newbridge may
assign all or part of its rights under this  Agreement  and delegate all or part
of its obligations under this Agreement to one or more Affiliates  identified to
TeleHub  in a  letter  delivered  simultaneously  with  the  execution  of  this
Agreement,  in which event all the rights and powers of  Newbridge  and remedies
available to it under this Agreement  shall extend to and be enforceable by each






                                       39
<PAGE>

such  assignee.  In the event of any such  assignment  and  delegation  the term
"Newbridge" as used in this Agreement  shall be deemed to refer to Newbridge and
each such  assignee of  Newbridge  where  reference  is made to actions or to be
taken with respect to the transactions  contemplated hereby, and shall be deemed
to  include  both  Newbridge  and each such  assignee  where  appropriate.  This
Agreement  shall be binding upon and inure to the benefit of the parties  hereto
and their permitted successors and assigns.

invalid or unenforceable  by any court of competent  jurisdiction or as a result
of future legislative action, such holding or action shall be strictly construed
and shall not affect the validity or effect of any other provision hereof.

                            ORGANIZATIONAL AGREEMENT
                              Schedules & Exhibits



                                   SCHEDULE I
                                   (BUSINESS)

         TeleHub   and   TTC    (collectively,    "Company")    have   developed
first-to-market   proprietary   software,   Virtual  Access  Services   Platform
("VASP(TM)")  that  will  enable  telecommunications  service  providers  to (i)
integrate  the delivery of voice,  video and data over a single  platform;  (ii)
seamlessly  interconnect  with the Public Switched  Telephone  Network ("PSTN");
(iii) provide  real-time  monitoring  of  telecommunications  traffic;  and (iv)
facilitate  local  exchange  competition.  The  Company  believes  the  VASP(TM)
platform addresses significant needs throughout the telecommunications  industry
for improved  systems and less  reliance on legacy  hardware.  VASP(TM)  creates
virtual  switching  capabilities,  permits  real-time  network  supervision  and
facilitates  the  introduction  of new service  offerings.  When fully deployed,
VASP(TM) will integrate  voice,  video and data on a single switched network and
enable the provisioning of bandwidth-on-demand services.

         The Company believes the VASP(TM) platform addresses  significant needs
throughout  the  telecommunications  industry  for  improved  systems  and  less
reliance on legacy  hardware.  While the legacy network evolved  principally for
voice transmission, demand for data, video and advanced voice services has grown
rapidly  over the past ten years.  The legacy  network,  designed  to handle the
lower  bandwidth  requirements of voice traffic,  has inherent  service and cost
inefficiencies  when carrying data and video  transmissions.  Existing  carriers
must develop new Operational Support Systems ("OSS") that are interoperable with
their  legacy  systems,  not  only to  support  initiatives  like  Local  Number
Portability  ("LNP") and the unbundling  requirements of the  Telecommunications
Act,  but  also  to  enable  carriers  to  respond  to  increasing   competitive
challenges.   VASP(TM)   addresses  several   shortcomings  of  legacy  networks
including:  (i)the  inability to switch packet- and cell-based  traffic into the
PSTN; (ii)the lack of real-time management, billing and monitoring capabilities;
(iii)the  inflexibility of hardware-based  network  architectures;  and (iv) the
lack  of  integrated  OSS  capabilities.   VASP(TM)  creates  virtual  switching
capabilities,   permits  real-time  network   supervision  and  facilitates  the
introduction  of new  service  offerings.  When fully  deployed,  VASP(TM)  will
integrate  voice,  video and data on a single  switched  network  and enable the
provisioning  of  bandwidth-on-demand  services  The Company  believes  that its
VASP(TM)  technology  provides  Incumbent  Local  Exchange  Carriers  ("ILECs"),
Competitive Local Exchange Carriers  (CLECs),  Inter-exchange  Carriers ("IXCs")
and Original Equipment Manufacturers ("OEMs") with the ability to accelerate the
introduction of new products and services, to reduce costs and to enter into new
markets rapidly.

         VASP(TM)'s  applications are designed to administer,  operate,  control
and manage switching devices and network elements in the public carrier services
market. The Company believes that VASP(TM) provides  telecommunications carriers
with superior billing,  management and control  capabilities.  VASP(TM) has been
designed  to  be  integrated   with  any  carrier's   customer  care,   billing,
provisioning  and  network   management   applications.   VASP(TM)   accumulates
information about network events for each phone call and generates a Transaction
Detail Record ("TDR").  The TDR can be converted into the standard industry call
detail record or into customized  information  that allows service  providers to
bill innovatively (e.g.,  millisecond billing).  In addition,  service providers
can access their databases  containing customer  information and individual call
records in real-time to trouble  shoot  problems and identify  customer  calling
patterns.  This  information  can be  obtained by simple  dial-up  access from a
personal  computer,  as opposed to the current  network  process of  downloading
information  from each switch in the network,  which can take more than a day to
complete.  The carrier can use such  information  as a strategic  advantage  for
pricing and offering targeted product based upon real-time market feedback.  The
Company's software can also be used as a network surveillance monitoring device.
The  software  has the  ability  to  track  phone  calls  from  end-to-end  and,

                              Schedules & Exhibits

therefore,  can  locate  the  specific  network  element  that may be  causing a
problem.  These  advantages,  coupled with the capability to provision  circuits
electronically, will significantly reduce carriers' operating costs.

          The Company  expects that future  releases of VASP(TM)  will allow for
the replacement of the Class  4/tandem.  switch and Class  5/end-office  switch.
Based upon engineering  studies, the Company believes that by using Asynchronous
Transfer Mode ("ATM") and VASP(TM) in place of traditional  switch fabrics,  the
reduction  in  tandem  switching  investment  will  lower  the  overall  cost of
multi-city interconnections by 45% to 60%. The VASP(TM) open system architecture
is scalable  from small sizes up to hundreds of phone calls per second,  and its
underlying  hardware  platforms and control  center designs are selected to meet
the  operating  objectives  by  accumulating  no more than one hour of  downtime
during  each  twenty  year  period of  service  (99.999%  uptime  service  level
objective).  VASP(TM) is also  adaptable to other  transmission  mediums such as
Internet  Protocol ("IP"),  cable and wireless.  VASP(TM)  products and services
include the following:

          Virtual  Class  4/Tandem.  The  Company  expects  that  its  software,
combined  with an ATM  switching  platform,  will be  capable of  replacing  the
traditional  Class 4/tandem  switch.  This  capability  will enable data service
providers to offer voice products over their existing networks.  VASPTM, running
on a Sun Microsystems  server and controlling ATM switches,  offers a 30% to 40%
savings over the cost of purchasing and installing  traditional tandem switches.
In addition  TeleHub's  VASP(TM) -based software solution offers other benefits,
including  cost  effective  scalability,   customization  to  specific  customer
requirements and applications, and faster introduction of new products.

          Local Switch Bypass. TTC is engineering solutions to identify Internet
data and other  long-holding  time  calls  (e.g.,  voice  mail)  and route  them
directly to called parties,  thereby  bypassing  end-office and tandem switches.
The Company  expects this  technology to address  carriers'  growing  problem of
congestion at end-office and tandem switches caused by Internet  traffic.  TTC's
solution  allows  carriers to manage  existing  traffic  levels and flow without
purchasing additional switch capacity.

          Virtual  Class  5/End-Office  Switching.  TeleHub is in the process of
enhancing its VASP(TM) solution to duplicate the basic  functionality of a Class
5/end-office  switch.  TeleHub  expects its virtual  Class 5 solution to provide
carriers with the capability to enter the local market with a voice product at a
fraction of the cost of buying and installing a conventional  Class 5/end-office
switch.  The same advantages offered by TeleHub's Class 4/tandem switch solution
apply   here  -  reduced   capital   expenditures,   customization   and  faster
time-to-market for new products.  As an example,  many CLECs have data Points of
Presence  ("POPs") which  currently  utilize ATM switches.  TeleHub  expects its
solution to allow CLECs to carry and switch voice traffic  using their  existing
ATM networks without purchasing Class 5/end-office switches.

          Virtual STP/SCP Signaling). Signal Transfer Points ("STPs") and Signal
Control Points  ("SCPs") are key elements of the underlying  Signaling  System 7
("SS7") network.  Messages,  such as telephone number,  calling card validation,
800 number routing, and calling name delivery are transmitted to STPs that route
the  messages to the proper SCPs where call  processing  information  is stored.
Embodied  within the VASP(TM)  design today are both SCP and STP  functionality,
thereby allowing carriers to perform their own SS7 signaling, without purchasing
signaling  services or expensive  equipment.  VASP(TM) contains  translation and
routing  instructions  needed to deliver  advanced  network  services and can be
further  enhanced as new services or requirements  are identiRed.  The necessary
STP  functions  are also  incorporated  in the  VASP(TM)  design to  handle  the
signaling and management of "on-net"  traffic.  Conventional  STP is deployed in
VASP(TM) as an  interface  to other  carriers in the Public  Switched  Telephone

Network  ("PSTN")  and  as a  firewall  to  protect  both  parties'  proprietary
information from compromise.

          Mediated  Access  Services  ("MAS').  The  Telecommunications  Act and
subsequent  FCC mandates  will  require  service  inter-operability  between the
various proprietary systems of existing  telecommunications  carriers. Local and
long  distance  carriers  and  their  current  software  vendors  are  therefore
expending significant design and software development resources trying to create
the inter- operability solutions that can be achieved through VASP(TM).  TeleHub
expects many carriers to select TeleHub as a service  supplier and VASP(TM) as a
standard product to integrate the various operating overlays.

          TeleHub  expects its MAS capability to provide  neutral  "third-party"
access to service  management  system and  Operational  Support  system  ("OSS")
databases   throughout   the  industry.   Any  service   provider   (virtual  or
facilities-based)  will be able to  obtain  the key call  treatment  information
necessary to process  customer calls,  while the proprietary  information of the
database owner is protected from compromise. The first requirement for mediation
results from the FCC's  mandated LNP that requires the Regional  Bell  Operating
Companies  ("RBOCs") and GTE  Corporation  ("GTE") to permit their  customers to
switch to another  competing  Local  Exchange  Carrier  ("LEC") and still retain
their same  telephone  number.  The Company  believes its MAS will encourage the
LECs to offer unbundled local service  elements to other carriers as required by
the  Telecommunications  Act. Management believes this is currently the greatest
hurdle for the RBOCs to overcome in achieving  their long standing goal of entry
into the long distance business within their regions.

         Switched  Virtual  Circuit  ("SVC').  The  Company is in the process of
developing  an  SVC  product   expected  to  provide  carriers  with  a  cheaper
alternative to permanent virtual circuit (i.e., point-to-point) products offered
today.  The  advantage  of a SVC is that when the circuit is not  utilized,  the
capacity can be  allocated  for another  use. A permanent  virtual  circuit must
allocate  bandwidth to the user  regardless of whether there is traffic  flowing
over the circuit.

TeleHub/Westel Joint Venture

         TeleHub  entered into a Software  License  Agreement as of July 1, 1998
with respect to the VASP(TM) (the  ASoftware  License  Agreement@)  with Citizen
Services Limited, a British Virgin Islands corporation (ACitizen@). TeleHub also
entered into a  Pre-Organization  Agreement with Citizen as of July 1, 1998 (the
APre-Organization Agreement@).

         Pursuant to an option deed entered into on July 9, 1998 between Citizen
and Westel Group  Limited,  an Australian  corporation  (AWestel@)  (the AOption
Deed@), Westel exercised its option and settlement of the Option Deed took place
on January 13, 1999. At such settlement,  the Software License Agreement and the
Pre-Organization  Agreement were assigned by Citizen to Westel under  Assignment
dated January 13, 1999 (the AAssignment@).

         The  Pre-Organization  Agreement  sets  out  the  structure  of a joint
venture between TeleHub and Westel. A new company  currently being  incorporated
in Western Australia under the name Advanced  Satellite Networks Pty Ltd (AASN@)
is being  established  to exploit the VASP(TM) in Australia  and other  selected
markets  world  wide.  ASN  will  be  developed  as  a  wholesale  international
telecommunications service provider, specializing in data and voice services and
also offering integrated voice/data/video services. It will offer these services
primarily to other carriers,  government agencies,  and medium to large business
markets in Australia and in selected overseas destinations.

         TeleHub and Westel will enter into an Operating  Agreement to establish
ASN, which Operating Agreement shall materially  incorporate all terms set forth
in the Pre-Organization  Agreement.  Under the Operating Agreement,  TeleHub and
Westel  will  have the  following  ownership  structure  and make the  following
contributions:

therein,  provided that in the event the System  incorporates  land-based  cable
connectivity  on an  as-needed  basis,  at  least  90% of the  System  shall  be
satellite-based.

         Under the Software License  Agreement,  TeleHub is obligated to deliver
the  VASP(TM) to Westel for  testing on a date to be  mutually  agreed on by the
parties. The testing period is 30 days following receipt of VASP(TM).  Within 45
days of Westel's  acceptance  of the  VASP(TM),  TeleHub must deliver a complete
copy of the then-current version of the VASP(TM) and all Documentation,  as such
term is defined in the Software License Agreement.

and support of the VASP(TM).

                  (c)  Newbridge  shall  have the  right to  appoint  three  (3)
         individuals  to the Board of  Directors  (the  "Newbridge  Directors").

         dies or is removed.  Any Director may be removed with or without  cause
         by the Stockholder which appointed such Director at any time; provided,
         however,  except  as set  forth in the last  sentence  of this  Section
         2.1(c)  the  removal of any  Additional  Director  requires  the mutual
         agreement of Newbridge and TeleHub.  Upon the resignation,  retirement,

         designate the replacement Director,  (B) any TeleHub Director,  TeleHub

         subsequent to the exercise of the Option  Agreement a Stockholder  owns
         in excess of fifty  percent of the Issued  Common Stock of the Company,
         such  Stockholder  shall  have the  right  to  appoint  the  Additional
         Director.

                  (d)  The  Company   shall  have  a   technology   subcommittee

         Company's Board of Directors. Newbridge shall have the right to appoint
         two (2)  individuals to the  technology  subcommittee  (the  "Newbridge
         Technology Directors"). TeleHub shall have the right to appoint two (2)
         individuals to the  technology  subcommittee  (the "TeleHub  Technology






                                       6
<PAGE>

         Directors").  Exhibit C attached  hereto sets forth the initial members
         of the technology subcommittee appointed by TeleHub and Newbridge. Each
         such  individual  shall  serve  until  such time as he or she  resigns,
         retires,  dies or is  removed.  Any  Director  may be  removed  with or
         without cause by the  Stockholder  which appointed such Director at any
         time.  Upon the  resignation,  retirement,  death or removal of (A) any
         Newbridge   Technology   Director,   Newbridge   shall   designate  the
         replacement Director, and (B) any TeleHub Technology Director,  TeleHub
         shall designate the replacement Director. In the event of a tie vote by
         the members of the technology subcommittee, the Chief Operating Officer
         of  the  Company  will  then  make  the  decision  for  the  technology
         subcommittee.  Any decision by the technology subcommittee or any other
         subcommittee  of  the  Board  of  Directors  may be  overturned  by the
         Company's Board of Directors.

                  The  Company's  Board of Directors  may  establish  additional
         committees,  including  without  limitation,  an  audit  committee  and
         compensation  committee,  consisting of at least one Director appointed
         by  each of  Newbridge  and  TeleHub.  Any  action  by a  committee  or
         subcommittee  established  by the Board of Directors  shall be taken by
         the  affirmative  vote of a majority of the Directors on such committee
         or  subcommittee or if taken by written consent then the consent of all
         Directors of the committee or subcommittee.

         2.2      Meetings and Actions of the Board of Directors.

         (a) The Board of  Directors  shall meet (x) at least once each month at

  by the Board of  Directors;  or (z) upon the request of at least a majority of

  delivered not less than  forty-eight (48) hours nor more than thirty (30) days
  before the date of the meeting. When any notice is required to be given to any
  Directors,  a waiver  thereof  in  writing  signed by such  Director,  whether
  before,  at, or after the time  stated  therein,  shall be  equivalent  to the
  giving  of such  notice.  A  Director's  attendance  at a meeting  shall  also
  constitute a waiver of notice as to such Director.  If all the Directors shall
  meet at any time and place,  and do not object to the  holding of a meeting at
  such time and place,  such meeting shall be valid without call or notice.  The
  Board of Directors  shall cause written  minutes to be prepared of all actions
  taken by the Board of Directors and shall cause a copy thereof to be delivered
  to each Director within fifteen (15) days thereof.  Both Newbridge and TeleHub
  may designate a member or members of their respective  management who shall be
  entitled to attend all meetings of the Company's Board of Directors.

  any  decision  made by the Board of  Directors.  Any action to be taken by the

                                       7
<PAGE>

  all  Directors.  A Director may grant a proxy  entitling  another  Director to
  exercise his voting rights. Such proxy shall be in writing and shall specify a
  termination  date. The other  Directors shall be entitled to inspect the proxy
  on demand.

         (d) Any  action  to be taken by the  Board  of  Directors  may be taken
  without a meeting if consents in writing  setting forth the action to be taken
  are signed by all the Directors.

         2.3 Budget.  Not less than sixty (60) days prior to the commencement of
   each fiscal  year of the  Company,  the Chief  Executive  Officer,  the Chief
   Operating Officer and the Chief Financial Officer shall prepare and submit to
   the Board of Directors and the Stockholders  for  consideration a budget (the

   the Board of Directors and the Stockholders, the Officers shall implement the
   Budget  and  shall be  authorized  to make the  expenditures  and  incur  the
   obligations  provided for in the Budget.  The  Officers  shall not pursue any

                                    SECTION 4

                            Additional Contributions.

         4.1 Additional  Contributions.  The Board of Directors may from time to
time determine based upon the Approval of the Board of Directors that additional
capital  ("Additional  Capital")  is needed to enable the Company to conduct its
business. Upon a determination that Additional Capital is required, the Board of
Directors  shall provide written notice to Newbridge of the amount of Additional





                                       10
<PAGE>

Capital  that is  required  and the date on which the  Company  wishes that such
Additional  Capital be provided to the Company.  Newbridge shall have the right,
but not the  obligation,  to provide  such  Additional  Capital as a loan to the
Company upon such terms and  conditions  as shall be mutually  acceptable to the
Company and  Newbridge.  The parties hereto  acknowledge  that it is Newbridge's
present  intention,  provided that no Material Adverse Change (as defined in the
Organizational  Agreement) shall have occurred with respect to the Company since
the date  hereof,  that  Newbridge  will  provide  a loan to the  Company  in an
aggregate  principal  amount of up to Ten Million  Dollars  ($10,000,000)  which
shall bear  interest at the prime rate of interest and have such other terms and
conditions  as shall be acceptable  to the Company and  Newbridge.  In the event
that  Newbridge  does not make such loan,  it shall  guarantee up to Ten Million
Dollars  ($10,000,000)  of  indebtedness  to be  provided  to the  Company  by a
financial institution  reasonably acceptable to Newbridge.  Such guarantee shall
be on such terms and  conditions  as Newbridge  typically  provides to financial
institutions  and shall terminate upon the earlier of (i) one year from its date
of issuance  or (ii) the  exercise  of the Option  Agreement  (as defined in the
Organizational Agreement dated March 31, 1999  ("Organizational  Agreement")) by
Newbridge.  To the  extent  the need for  Additional  Capital  shall  exceed Ten
Million Dollars ($10,000,000), the Company shall, subject to the Approval of the
Stockholders,  seek to raise the Additional  Capital  through (i) a Public Sale,
(ii) a  private  placement  of debt or  equity  of the  Company,  (iii) a credit
facility from a financial institution  satisfactory to the Board of Directors or
(iv) such other  means as shall be Approved  by the Board of  Directors.  In the
event that after pursuing all of the  alternative  set forth above,  the Company
has not met its need for Additional  Capital in full (the "Remaining  Additional
Capital"),  each Stockholder  shall have the right,  but not the obligation,  to
loan to the Company its Pro Rata Share of the Remaining  Additional  Capital. If
both  Stockholders  lend  their Pro Rata  Share of the  Remaining  Capital,  the
interest  rate on such  loans  shall  be the  prime  rate of  interest.  If both
Stockholders  do not make such loans,  the loan made by such  Stockholder  shall
bear  interest at a rate equal to 15% per annum.  All such loans shall have such
additional  terms and  conditions  as shall be acceptable to the Company and the
Stockholder loaning such Remaining Additional Capital.  Each Stockholder wishing
to exercise  such right (i) must notify the Company of its  intention  within 30
days of the  giving of notice of such  determination  by the Board of  Directors
that  Remaining  Additional  Capital is needed,  and (ii) must loan its Pro Rata
Share of the Remaining Additional Capital within 30 days thereafter.

                                    SECTION 5

                    Restrictions on Transfer of Common Stock.

         5.1 Transfer of Common Stock;  Other  Restrictions on Stockholders.  No
Stockholder  shall Dispose any interest in any Common Stock,  except pursuant to
or after compliance  with, as applicable,  (i) the provisions of this Section 5,
(ii) a Public  Sale,  (iii) an  Approved  Sale,  (iv)  the  grant of a  security
interest under the Pledge Agreement,  and (v) the Pledge Agreement in connection
with an enforcement  by the Collateral  Agent of its rights and remedies for the
benefit of the holders of the Notes. Any Disposition or attempted Disposition of
any Common Stock in violation of any provision of this Agreement  shall be void,
and the  Company  shall  not  record  such  transfer  on its  books or treat any
purported  transferee of such Common Stock as the owner of such Common Stock for






                                       11
<PAGE>

any purpose  provided  that, in each case,  the  restrictions  contained in this
Agreement  will  continue  to be  applicable  to  the  Common  Stock  after  any
Disposition  pursuant to this Section 5 and such transferor(s)  shall cause such
Transferee(s)  of such  Common  Stock  to agree  in  writing  to be bound by the
provisions  of this  Agreement,  including  without  limitation,  Section  14.22
hereof.  Upon the  Disposition of Common Stock pursuant to this  Agreement,  the
Transferees  will  deliver a written  notice to the  Company,  which notice will
disclose in reasonable detail the identity of such transferee.

         5.2 Permitted Dispositions. Notwithstanding anything to the contrary in
any other  provision  of this  Agreement,  the  restrictions  contained  in this
Section 5 shall not apply to  Dispositions by any Stockholder to or among any of
its Affiliates  provided that, in each case, the restrictions  contained in this
Agreement  will  continue  to be  applicable  to  the  Common  Stock  after  any
Disposition  pursuant to this Section 5 and such transferor(s)  shall cause such
Transferee(s)  of such  Common  Stock  to agree  in  writing  to be bound by the
provisions of this  Agreement.  Upon the Disposition of Common Stock pursuant to
this Section 5, the  Transferees  will deliver a written  notice to the Company,
which notice will disclose in reasonable detail the identity of such transferee.

         5.3 Permitted  Sales.  (a) In the case any entity makes an  unsolicited
bona fide offer (the "Bid") for any Common  Stock of the  Company,  TeleHub will
notify Newbridge  within  forty-eight (48) hours of the Bid. TeleHub shall allow
Newbridge  fifteen  (15) days to make its own offer on the  equivalent  share of
Common Stock of the Company (the  "Counter")  before  TeleHub shall proceed with
any transaction.  In no event shall TeleHub, with respect to any individual Bid,
sell any of Common Stock in the Company to another Person for a price lower than
the Counter.

         (b) In the case any Listed Third Party makes an  unsolicited  bona fide
offer (the "Listed  Party Bid") for any Common  Stock of the Company  during the
first twelve months subsequent to the date hereof, TeleHub will notify Newbridge
within  forty-eight  (48) hours of receipt of the Listed Party Bid,  accompanied
with a copy of the Listed Third Party Bid. TeleHub shall allow Newbridge fifteen
(15) days to make its own offer on the  equivalent  share of Common Stock of the
Company before TeleHub shall proceed with any transaction. If Newbridge does not
make such offer or Telehub  rejects the offer made by  Newbridge  (the  "Telehub
Rejection"),  within  fifteen (15) days after  receipt of written  notice of the
Telehub  Rejection,  Newbridge  shall either  exercise the Tag-Along  Rights set
forth in Section 5.4 hereof or instruct TeleHub to reject the Listed Third Party
Bid. If  Newbridge  instructs  TeleHub to reject the Listed  Thirty Party Bid or
does not  respond to the Listed  Third Party Bid within  such  fifteen  (15) day
period (a "Rejection"),  TeleHub shall reject the Listed Third Party Bid. In the
event if a  Rejection,  the  Stockholders  agree that the  Company  may pursue a
Public Sale.

         (c) During  the first  twelve  months  subsequent  to the date  hereof,
TeleHub shall not solicit, initiate, encourage or assist any entity in making an
Acquisition  Proposal (as defined in the  Organizational  Agreement);  provided,
however,  the foregoing shall not restrict the Collateral  Agent subsequent to a
foreclosure  on the  Issued  Common  Stock of  TeleHub  pursuant  to the  Pledge
Agreement.

         5.4 Tag-Along Rights. (a) In the event that then Stockholders which are
not Newbridge (the "Non-Newbridge Stockholders") desire to make a Disposition of
their Issued  Common Stock to a Listed  Third Party in a single  transaction  or
series of related  transactions,  Newbridge  shall  have the right,  but not the
obligation (the "Tag-Along Right"), to require the Non-Newbridge Stockholders to
require the Listed  Third Party to acquire  one  hundred  percent  (100%) of the
Issued Common Stock and to sell to the proposed purchaser or purchasers,  at the
price  and  on  the  other  material  terms  established  by  the  Non-Newbridge
Stockholders  for such  Disposition,  either (i) all of the Issued  Common Stock
owned by Newbridge  or (ii) that number of shares of Issued  Common Stock (or if
such number is not an integral number, the next integral number which is greater
than such  number)  which shall be the product of (A) the total number of shares
of Issued Common Stock owned by Newbridge,  and (B) a fraction, the numerator of
which  shall be the  number of shares of Issued  Common  Stock to be sold by the
Non-Newbridge  Stockholders  and the  denominator  of which  shall be the  total
number of shares of Issued Common Stock owned by the Non-Newbridge Stockholders.
The Issued  Common Stock held by  Newbridge  to be sold  hereunder to the Listed
Third Party shall be sold on the same terms and  conditions as those  applicable
to  the  Non-Newbridge  Stockholders,  including  the  time  of  sale,  form  of
consideration and per share price.  Newbridge's failure to exercise rights under
this  Section 5.4 shall  result in exclusion  from sale in the  transaction.  If
Newbridge  desires to exercise its rights  under this  Section 5.4,  such Person
shall give written notice  thereof to the  Non-Newbridge  Stockholders  no later
than fifteen  (15) days after  receipt of notice  provided by the  Non-Newbridge
Stockholder. If Newbridge desires to exercise its rights under this Section 5.4,
it shall promptly take all necessary  steps to effectuate the sale of the Issued
Common Stock covered thereby,  including,  but not limited to, the furnishing of
information  customarily  provided  in  connection  with  such  a sale  and  the
execution of such sales and other transfer documents with such  representations,
warranties, agreements, covenants and indemnities as may reasonably be required.
All references to "sell" herein shall be deemed to include transfer,  dispose of
or otherwise  convey in the manner in which such  Disposition  is proposed to be
made.

         (b) If Newbridge does not exercise its right to cause the Non-Newbridge
Stockholder to require the Listed Third Party to acquire one hundred  percent of
the Issued  Common  Stock,  then if the sum of (i) the Issued Common Stock to be
sold by the Non-Newbridge  Stockholders and (ii) Issued Common Stock offered for
sale  pursuant to the exercise of the  Tag-Along  Right  pursuant to Section 5.4
hereof exceeds the number of shares of Issued Common Stock that the purchaser or
purchasers described in the notice provided by the Non-Newbridge  Stockholder is
willing to buy,  the  Stockholders  shall  adjust the number of shares of Issued
Common  Stock to be sold by the  Non-Newbridge  Stockholder  and by Newbridge to
ensure that the ratio of the number of shares of Issued Common Stock proposed to
be sold by each such holder to the number of shares of Issued Common Stock owned
by such holder shall be equal for each  selling  Non-Newbridge  Stockholder  and
Newbridge.

         5.5 Termination of  Restrictions.  Except for the Tag-Along  Rights set
forth in Section 5.4 above which shall  terminate one year from the date hereof,
the  restrictions set forth in this Section 5 will continue with respect to each
Stockholder  until the  earlier of (i) the  Disposition  by  Newbridge  Networks
Corporation or TeleHub  Technologies  Corporation (other than to its Affiliates)
of twenty-five  percent (25%) the Issued Common Stock,  (ii) an Approved Sale or
(iii) a Public Sale.

                              Sale of the Company.

         7.1  Approved  Sale.  If the  Stockholders  Approve  a  sale  of all or
substantially all of the Company's assets determined on a consolidated  basis or
a sale of all or substantially  all of the Company's  outstanding  capital stock
(whether by merger, recapitalization, consolidation, reorganization, combination
or otherwise) to any one or more Independent Third Parties (an "Approved Sale"),
then each  Stockholder  will  consent  to and raise no  objections  against  the
Approved  Sale.  If  the  Approved  Sale  is  structured  as  a  (i)  merger  or
consolidation,  each Stockholder  shall waive any dissenters  rights,  appraisal
rights or similar rights in connection with such merger or consolidation or (ii)
sale of stock,  each Stockholder  shall agree to sell all of its Common Stock on
the terms and conditions  Approved by the  Stockholders.  Each Stockholder shall
take all necessary or desirable  actions in connection with the  consummation of
the Approved Sale as requested by the Company.

         7.2 Terms of Sale. The obligations of a Stockholder with respect to the
Approved Sale are subject to the satisfaction of the following  conditions:  (i)
upon the consummation of the Approved Sale, each  Stockholder  shall receive the
same form of consideration  and the same portion of the aggregate  consideration
such  holder  would  have  received  if such  aggregate  consideration  had been
distributed  by the Company in complete  liquidation  pursuant to the rights and
preferences set forth in the Company's Certificate of Incorporation as in effect
immediately  prior to the consummation of the Approved Sale; (ii) if any holders
of a class of Common  Stock  are  given an  option as to the form and  amount of
consideration to be received,  each Stockholder  shall be given the same option;
and (iii) each holder of then currently convertible, exchangeable or exercisable
rights to  acquire  a class of Common  Stock  shall be given an  opportunity  to
either (A) exercise such rights prior to the  consummation  of the Approved Sale
and  participate in such sale as holders of such class of Common Stock or (B) to
sell as part of such  Approved  Sale  securities  convertible,  exchangeable  or
exercisable  for  Common  Stock  at a price  equal to the  full  purchase  price

thereof as part of the Approved  Sale,  reduced by the aggregate  exercise price
for such securities.

         7.3 Sale Expenses;  Indemnity.  (a) Each  Stockholder will bear its Pro
Rata Share of the costs of any sale of Common Stock pursuant to an Approved Sale
to the extent such costs are incurred  for the benefit of all such  Stockholders
and are not otherwise paid by the Company or the acquiring party. Costs incurred
by a Stockholder on its own behalf will not be considered  costs of the Approved
Sale.  Each  Stockholder  shall be  obligated to join on a Pro Rata Basis in any
indemnification  or other  obligations that are part of the terms and conditions
of the Approved Sale (other than any such obligations  that relate  specifically
to  a  particular   Stockholder,   such  as  indemnification   with  respect  to
representations   and   warranties   given  by  a  Stockholder   regarding  such
Stockholder's  title to and ownership of Common  Stock) (the "Company  Indemnity
Obligations").

         (b) In no event shall any  Stockholder be obligated in connection  with
any Approved  Sale to agree to indemnify or hold harmless the  transferees  with
respect  to  Company  Indemnity  Obligations  in an  amount in excess of the net
proceeds paid to such holder in connection with the Approved Sale.

         7.4 Termination of  Restrictions.  The  restrictions  set forth in this
Section 7 will terminate  automatically and be of no further force and effect on
the first to occur of (i) the Disposition by Newbridge or TeleHub (other than to

                                    SECTION 8

                          Business Plan of the Company

         8.1 Goals.  Newbridge and TeleHub wish to form a new venture to further
develop the Virtual Access Services Platform ("VASP(TM)") technology and related
products   that  are   essential   to   world-wide,   end-to-end,   service-rich
communications, as more fully described in Exhibit G hereto (the "Business") and
expand the  market  for the  Business.  The goal of the new  venture  will be to
establish  a  successful,   highly  profitable  market  position  for  VASP(TM),
specifically   addressing  narrowband  switch  replacement  and  data  services,
addressing the needs of incumbent  carriers and alternative  carriers,  in North
America and Internationally. In doing so, the new venture will meet the needs of
Newbridge  and Telehub,  by  delivering a best of breed  product that allows the
users of the technology  competitive advantage in their markets. The new venture
will be implemented through the Company.  Telehub and Newbridge wish the Company
to operate as a new venture with the two principal  shareholders,  Newbridge and
Telehub,  operating in a spirit of cooperation and  collaboration to address the
emerging  narrowband switch  replacement and data services markets and to grow a
profitable venture which leads these markets.

Newbridge  have jointly  prepared a schedule  specifying  the roll-out plan for,
VASP(TM),  which  schedule,  dated as of the date hereof,  is attached hereto as
Exhibit H. This Schedule will give equal  priority to the use of VASP(TM) in the
TeleHub  Network  Services  Corporation  network  and the  requirements  for the
broader  market,  which are  necessary  for the  Company to achieve  establish a
successful,  highly  profitable  market  position  for  VASP(TM),   specifically
addressing  narrowband switch  replacement and data services,  or addressing the

integration  of  the  VASP(TM)  with   Newbridge's   MainStreetXpress(R)   36170
Multi-Service Switch and related technologies  ("Newbridge  Technology") for the
contribution   of  Newbridge's   own  efforts  with  respect  to  the  Newbridge
Technology.  TeleHub and  Newbridge  agree that the technical  capabilities  and
roll-out  plan set forth in the  Schedule in Exhibit H are  intended to position
VASP(TM)  as a viable and  superior  Call  Control  platform  for  domestic  and
international  telecommunications  common  carriers,  and will  provide  for the
ability for such carriers to offer convergent  network services for voice, video
and data  communications.  Newbridge  agrees to regularly  inform TeleHub on the







                                       16

status of  Newbridge  Technology,  and advise  TeleHub and TTC of any changes in
Newbridge Technology to ensure compatibility  between VASP(TM) and the Newbridge
Technology.  TTC agrees to  regularly  inform  Newbridge  on the status of TTC's
VASP(TM)  technology  and  advise  Newbridge  of any  changes  in such  VASP(TM)
technology to ensure adherence to the schedule described in Exhibit H.

         8.3 Milestones.  TeleHub and TTC acknowledge that  Newbridge's  product
requirements  of the VASP(TM)  (feature and schedule) are a material  reason for
the stock purchase by Newbridge and a primary  inducement to Newbridge to assist
in the development  and management of TTC.  Newbridge and Telehub agree that the
following  milestones  must be met in order for TTC and Newbridge to establish a
successful,  highly  profitable  market  position  for  VASP(TM),   specifically
addressing narrowband switch replacement:

                  (a)  Reliability:  The VASP(TM) shall improve failover time to
         no longer than 30 seconds. No existing calls shall be dropped. Delivery
         date for customer deployable functionality: See Exhibit H.

                  (b) European  Signalling:  The VASP(TM) shall support European
         variants  of the SS7  protocol  for at least 3  countries.  The initial
         countries to be addressed should be United Kingdom, France and Germany.
         Delivery date for customer deployable functionality: See Exhibit H.

                  (c) European  Numbering  Plan:  The VASP(TM)  shall support an

         8.4 Product  Plans.  Newbridge and TTC shall orient their product plans
and sales and  marketing  plans  towards the  objective of winning the following
reference  customers  by the end of 1999:  2 North  American  incumbent  carrier
customers  such as Bell  Atlantic or South  Western  Bell, 2 European  incumbent
carrier customers such as Deutsche Telecom or Compagnie  Generale d'Eaux Telecom
(CEGETEL), and 2 alternative carriers.

         8.5  Allowances.   TTC  shall  also  make  allowances  in  the  product
development schedule for unforeseen  requirements of the above target customers,
while maintaining the schedules included in Exhibit H.

         8.6  Distribution.  Both  TTC and  Newbridge  will  participate  in the
marketing of VASP(TM)  and other TTC  products.  Newbridge  and TTC will jointly
create a list of key customers and identify the customers  that  Newbridge  will
solicit  and those that TTC will  solicit.  TTC agrees that  customers  in which
Newbridge has already established a presence are better served by Newbridge than
by TTC. Notwithstanding the foregoing,  this Section 8.6 does not give Newbridge
any account exclusivity with respect to TTC's other channels.

                                    SECTION 9

                               Piggy-back Rights.

         (a) Except as set forth in Section 5.3(b), no sooner than twelve months
from the date  hereof,  the Company may conduct a Public Sale when  requested by
either  TeleHub or Newbridge.  Discussions  regarding a Public Sale may begin if
the  requesting  party  provides a commitment  from an investment  banker with a
national capability to underwrite the proposed Public Sale;  provided,  however,
the  Company  may  conduct a Public  Sale at any time  after the date  hereof if
TeleHub and Newbridge mutually agree that the Company may do so.

         (b) If the Company at any time  proposes to register  any of the Common
Stock under the Securities Act by  registration  on Forms S-1, S-2 or S-3 or any
successor or similar form(s), whether or not for sale or for its own account, it
will each time give prompt written notice to the  Stockholders  of its intention
to do so.  Upon the  written  request of any  Stockholder  made as  promptly  as
practicable and in any event within 15 days after the receipt of any such notice
(which request shall specify the Common Stock intended to be disposed of by such
Stockholder), the Company will use commercially reasonable efforts to effect the
registration  under the Securities Act of all Common Stock which the Company has
been so requested to register by any Stockholder; provided, however, that if, at
any time after  giving  written  notice of its  intention to register any Common
Stock and prior to the effective  date of the  registration  statement  filed in
connection  with such  registration,  the Company shall determine for any reason
not to register or to delay  registration of such Common Stock, the Company may,
at its election,  give written notice of such  determination to the Stockholders
and (i) in the case of a determination not to register, shall be relieved of its
obligation to register any Common Stock in connection with such registration and
(ii) in the case of a determination to delay registering,  shall be permitted to
delay  registering  any  Common  Stock  for the  same  period  as the  delay  in
registering such other Common Stock.

         (c) If the managing  underwriter  of any  underwritten  offering  shall
inform the Company of its belief that the Common  Stock plus other  Common Stock
of the Company  requested to be included in such  registration  would materially
adversely  affect  such  offering,   then  the  Company  will  include  in  such
registration,  to the extent of the Common Stock which the Company is so advised
by the  managing  underwriter  can be sold  in (or  during  the  time  of)  such
offering, first, all Common Stock proposed by the Company to be sold for its own
account, second, such Common Stock requested to be included in such registration
by the Stockholders and other shareholders,  such Common Stock to be included in
such  registration pro rata among the Stockholders and other  shareholders  with
similar  registration  rights  according to the total number of shares of Common
Stock requested to be included in such registration by the Stockholders or other
shareholders, as the case may be, and third, all other Common Stock requested to
be included in such registration.

         (d) In the event that the Board of  Directors  of the  Company  and the
Stockholders  Approve  a  Public  Sale  pursuant  to an  effective  registration
statement under the Securities Act, the Stockholders  will take all necessary or
desirable actions in connection with the consummation of the Public Sale. In the
event  that  such  Public  Sale is an  underwritten  offering  and the  managing
underwriters  advise the  Company in writing  that in their  opinion  the common







                                       18
<PAGE>

stock structure will adversely affect the  marketability  of the offering,  each
Stockholder  will  consent  to and vote for a  recapitalization,  reorganization
and/or   exchange  of  the  Common  Stock  into  securities  that  the  managing
underwriters, the Board of Directors of the Company and Stockholders Approve and
will take all necessary or desirable actions in connection with the consummation
of the recapitalization, reorganization and/or exchange; provided, however, that
the resulting  securities  reflect and are consistent  with the economic  values
reflected by the rights and preferences  set forth in the Company's  Certificate
of  Incorporation,  as amended,  as in effect  immediately  prior to such Public
Sale.

                                   SECTION 10

                               Stock Certificates.

         10.1  Legend.  (a) A copy of this  Agreement  shall be  filed  with the
Secretary of the Company and kept with the records of the  Company.  Each of the
Stockholders hereby agrees that each outstanding certificate representing shares
of Common Stock shall bear an endorsement reading substantially as follows:

                 ENCUMBERED,  DISPOSED  OF OR OTHERWISE  TRANSFERRED  EXCEPT  IN

                 THE PRINCIPAL EXECUTIVE OFFICES OF NEWCO.


                  (b) No  holder of the  Common  Stock  may  sell,  transfer  or
dispose  of any Common  Stock  (except  pursuant  to an  effective  registration
statement under the Securities  Act) without first  delivering to the Company an
opinion of counsel (reasonably  acceptable in form and substance to the Company)
that  neither  registration  nor  qualification  under  the  Securities  Act and
applicable state securities laws is required in connection with such a transfer.

                  (a) a  receiver,  liquidator,  assignee,  custodian,  trustee,
conservator, sequestrator (or other similar official) shall take possession of a
Stockholder or any substantial  part of its property  without its consent,  or a
court  having  jurisdiction  in the  premises  shall enter a decree or order for

any of the foregoing; or

                  (c) a Stockholder  shall admit in writing its inability to pay
its debts as they mature; or

                  (d)   (i)   the   insolvent    stockholder   (the   "Insolvent
Stockholder")   shall  promptly  notify  the  other  Stockholder  (the  "Solvent
Stockholder") of the occurrence of any such Insolvency Event, which notice shall
comply with Section  14.4 hereof,  and, if the  Insolvent  Stockholder  fails to
provide such notice and the Solvent Stockholder becomes aware that the Insolvent
Stockholder  has become such for purposes of this Section 13.1, then the Solvent
Stockholder shall promptly notify the Insolvent  Stockholder of such fact, which
notice shall comply with Section 14.4 hereof;

         (ii)  after  issuance  of any  notice  referred  to in  clause  (i),  a
Stockholder  (the "Selling  Stockholder"),  shall promptly provide notice to the
other Stockholder (the "Remaining Stockholder") when the Selling Stockholder has
received a bona fide offer by an  unaffiliated  third  party (the  "Third  Party
Offeror")  for the purchase of such Selling  Stockholder's  Issued Common Stock,
which notice shall (1) specify the number of shares of Issued Common Stock to be
sold, the name and address of the person  desiring to purchase the same, and the
purchase  price and terms of payment of such sale,  and (2)  contain an offer to
sell such Issued Common Stock to the Remaining Stockholder on the same terms and
conditions as the offer for the Issued Common Stock by the Third Party  Offeror,
whereupon the Remaining Stockholder shall have thirty (30) days after receipt of
such notice,  to elect by written notice to the Selling  Stockholder to purchase
any portion or all of the Issued Common Stock offered for sale; and

         (iii) the  provisions of this Section 13.1 shall in no respect  hinder,
delay or prevent the Collateral  Agent from taking  ownership and control of any
Collateral  under the terms and  conditions of the Pledge  Agreement,  including
assuming TeleHub Technology Corporation's rights to receive dividends,  exercise
voting and other  consensual  rights,  and  declare  certain  Obligations  to be
immediately due and payable under the terms of the Notes.

         13.2     Breach of Covenants; Failure to Perform Obligations

                  (a) If any Stockholder fails to perform any of its obligations
or  covenants  or breaches any of its  representations  hereunder  (an "Event of
Default"),  then the other Stockholder (the  "Nondefaulting  Stockholder") shall
have the right to give such party  (the  "Defaulting  Stockholder")  a notice of
default ("Notice of Default").  The Notice of Default shall set forth the nature
of the obligations which the Defaulting Stockholder has not performed.

                  (b) If within the thirty (30) day period following  receipt of
the Notice of Default,  the Defaulting  Stockholder  in good faith  commences to
perform such  obligations  and cure such default,  and thereafter  prosecutes to







                                       22
<PAGE>

completion  with  diligence  and  continuity  the curing  thereof and cures such
default  within a  reasonable  time,  then it shall be deemed that the Notice of
Default  was not  given  and the  Defaulting  Stockholder  shall  lose no rights
hereunder.  If, within such 30 day period,  the Defaulting  Stockholder does not
commence  in good  faith  the  curing  of such  default  or does not  thereafter
prosecute to completion with diligence and continuity the curing thereof and the
default is a material  default  hereunder,  then the  Nondefaulting  Stockholder
shall have the rights set forth in Section 13.2(c) below.

                  (c) If any  material  default  is not  cured  as set  forth in
Section 13.2(b),  the Defaulting  Stockholder,  shall promptly provide notice to
the  Nondefaulting  Stockholder  when the Defaulting  Stockholder has received a
bona fide offer by a Third  Party  Offeror for the  purchase of such  Defaulting
Stockholder's  Issued Common Stock, which notice shall (1) specify the number of
shares of Issued  Common  Stock to be sold,  the name and  address of the person
desiring to purchase the same,  and the  purchase  price and terms of payment of
such sale,  and (2)  contain an offer to sell such  Issued  Common  Stock to the
Nondefaulting  Stockholder on the same terms and conditions as the offer for the
Issued  Common Stock by the Third Party  Offeror,  whereupon  the  Nondefaulting
Stockholder  shall have thirty (30) days after receipt of such notice,  to elect
by written notice to the  Defaulting  Stockholder to purchase any portion or all
of the Issued Common Stock offered for sale.

                  (d) The  provisions  of this  Section 13.2 shall in no respect
hinder,  delay or prevent the Collateral Agent from taking ownership and control
of any  Collateral  under the  terms and  conditions  of the  Pledge  Agreement,
including assuming TeleHub Technology Corporation's rights to receive dividends,
exercise voting and other consensual rights, and declare certain  Obligations to
be immediately due and payable under the terms of the Notes.

                  (e) Failure by a Nondefaulting  Stockholder to give any Notice
of Default as specified herein, or any failure to insist upon strict performance
of any of the terms of this Agreement, shall not constitute a waiver of any such
breach or any of the terms of this  Agreement.  No breach shall be waived and no
duty to be performed shall be altered or modified except by written  instrument.
One or more  waivers  or  failures  to  give  Notice  of  Default  shall  not be
considered  as a  waiver  of a  subsequent  or  continuing  breach  of the  same
covenant.

         13.3 Not  Exclusive  Remedy.  The rights  granted  in Section  13.1 and
Section  13.2 above shall not be deemed an exclusive  remedy of a  Nondefaulting
Stockholder or a Solvent Stockholder,  but all other rights and remedies,  legal
and equitable, shall be available to it.

                                   SECTION 14

                                 Miscellaneous.

         14.1  Agreement  May Be  Modified.  This  Agreement  may be modified as
provided  in this  Section 14 (as the same may,  from time to time be  amended).
This  Agreement  may be amended or modified  from time to time only by a written
instrument Approved by the Stockholders.

         14.9 Entire  Agreement;  Severability.  This  Agreement,  the  Exhibits
hereto, and the Organizational Agreement, constitutes the entire agreement among
the parties hereto with respect to the subject  matter  hereof.  Any other prior
written  agreements  shall,  upon the execution of this  Agreement,  be null and
void.  The  parties  agree  that if any  term  or  provision  of this  Agreement
contravenes or is invalid under any federal, state or local law, court decision,
rule,  ordinance or regulation,  this Agreement  shall,  as to the  jurisdiction
under which such legal authority is promulgated or rendered,  be construed as if
it did not contain the offending term or provision, and the remaining provisions
of this Agreement shall not be affected thereby; provided,  however, that if the
removal of such  offending  term or provision  materially  alters the burdens or
benefits  of any of the  parties  under this  Agreement,  the  parties  agree to
negotiate in good faith such  modifications to this Agreement as are appropriate
to ensure the burdens and benefits of each party under such  modified  Agreement
are reasonably  comparable to the burdens and benefits  originally  contemplated
and expected.

         14.10 Captions.  The captions are inserted for convenience of reference
only and shall not affect the construction of this Agreement.

         14.11  Statutory  References.  Each  reference  in this  Agreement to a
particular  statute or regulation,  or a provision  thereof,  shall be deemed to
refer to such statute or regulation,  or provision thereof, or to any similar or
superseding statute or regulation, or provision thereof, as is from time to time
in effect.

         14.12 Waiver. The waiver by any party hereto of the breach of any term,
covenant,  agreement or condition  herein contained shall not be deemed a waiver
of any subsequent breach of the same or any other term,  covenant,  agreement or
condition herein,  nor shall any custom,  practice or course of dealings arising
among the parties hereto in the  administration  hereof be construed as a waiver
or  diminution  of the right of any  party  hereto  to  insist  upon the  strict
performance  by any other party hereto of the terms,  covenants,  agreements and
conditions herein contained.

         14.13  Remedies  Not  Exclusive.  Unless  otherwise  provided  in  this
Agreement,  any remedy  contained in this  Agreement for breaches of obligations
hereunder  shall not be deemed to be exclusive and shall not impair the right of
any party to exercise any other right or remedy, whether for damages, injunction
or otherwise.

         14.14  Remedies.  The parties to this Agreement  acknowledge  and agree
that breach of any of the covenants of the Company or the Stockholders set forth
in this  Agreement  is not fully  compensable  by payment of money  damages and,
therefore,  that the covenants of the Company and/or the  Stockholders set forth
in this  Agreement  may be  enforced  in equity by a decree  requiring  specific
performance.  Without limiting the foregoing,  if any dispute arises  concerning
the sale or other  disposition  of any of the shares of Common Stock  subject to
this  Agreement,  the parties to this Agreement  agree that an injunction may be
issued  restraining the sale or other disposition of such shares of Common Stock
or  rescinding  any such sale or other  disposition,  ending  resolution of such
controversy.  Such remedies shall be cumulative and nonexclusive and shall be in
addition  to any other  rights  and  remedies  the  parties  may have under this
Agreement.

         14.16 No Presumption  Against Drafter.  The parties hereto have jointly
participated in the negotiation and drafting of this Agreement.  In the event of
an ambiguity or if a question of intent or interpretation arises, this Agreement
shall be  construed  as if drafted  jointly by all of the parties  hereto and no
presumptions or burdens of proof shall arise favoring any party by virtue of the
authorship of any of the provisions of this Agreement.

         14.17  Recapitalization,   Exchanges,   Etc.  The  provisions  of  this
Agreement  shall  apply,  to the full extent set forth  herein  with  respect to

take any other action affecting the  capitalization  of the Company for a period
of one year from the date hereof.

Common  Stock of the Company  acquired  after the date of this  Agreement by the
Stockholders shall be subject to all terms and conditions of this Agreement, and
any  reference in this  Agreement to Common Stock shall  include any such Common
Stock acquired after the date of this Agreement.

         14.20  Reservation  of  Other  Business   Opportunities.   No  business
opportunities other than those actually exploited by the Company shall be deemed
to be property of the Company and any Stockholder or Director (unless  otherwise
restricted  by another  agreement  with the Company) may engage in or possess an
interest in any other business  venture,  independently  or with others,  of any
nature  or  description,  even if  such  venture  or  opportunity  is in  direct
competition with the business of the Company;  and (unless otherwise  restricted
by another  agreement with the Company) neither  Stockholder or any Director nor
the Company shall have any rights or obligations by virtue hereof in and to such

harmless the Company from any and all damages,  costs,  expenses or  liabilities
suffered  by the  Company  arising  out of or related to the  provision  of such

                                   (BUSINESS)

         TeleHub   and   TTC    (collectively,    "Company")    have   developed
first-to-market   proprietary   software,   Virtual  Access  Services   Platform
("VASP(TM)")  that  will  enable  telecommunications  service  providers  to (i)
integrate  the delivery of voice,  video and data over a single  platform;  (ii)
seamlessly  interconnect  with the Public Switched  Telephone  Network ("PSTN");
(iii) provide  real-time  monitoring  of  telecommunications  traffic;  and (iv)
facilitate  local  exchange  competition.  The  Company  believes  the  VASP(TM)
platform addresses significant needs throughout the telecommunications  industry
for improved  systems and less  reliance on legacy  hardware.  VASP(TM)  creates
virtual  switching  capabilities,  permits  real-time  network  supervision  and
facilitates  the  introduction  of new service  offerings.  When fully deployed,
VASP(TM) will integrate  voice,  video and data on a single switched network and
enable the provisioning of bandwidth-on-demand services.

         The Company believes the VASP(TM) platform addresses  significant needs
throughout  the  telecommunications  industry  for  improved  systems  and  less
reliance on legacy  hardware.  While the legacy network evolved  principally for
voice transmission, demand for data, video and advanced voice services has grown
rapidly  over the past ten years.  The legacy  network,  designed  to handle the
lower  bandwidth  requirements of voice traffic,  has inherent  service and cost
inefficiencies  when carrying data and video  transmissions.  Existing  carriers
must develop new Operational Support Systems ("OSS") that are interoperable with
their  legacy  systems,  not  only to  support  initiatives  like  Local  Number
Portability  ("LNP") and the unbundling  requirements of the  Telecommunications
Act,  but  also  to  enable  carriers  to  respond  to  increasing   competitive
challenges.   VASP(TM)   addresses  several   shortcomings  of  legacy  networks
including:  (i)the  inability to switch packet- and cell-based  traffic into the
PSTN; (ii)the lack of real-time management, billing and monitoring capabilities;
(iii)the  inflexibility of hardware-based  network  architectures;  and (iv) the
lack  of  integrated  OSS  capabilities.   VASP(TM)  creates  virtual  switching
capabilities,   permits  real-time  network   supervision  and  facilitates  the
introduction  of new  service  offerings.  When fully  deployed,  VASP(TM)  will
integrate  voice,  video and data on a single  switched  network  and enable the
provisioning  of  bandwidth-on-demand  services  The Company  believes  that its
VASP(TM)  technology  provides  Incumbent  Local  Exchange  Carriers  ("ILECs"),
Competitive Local Exchange Carriers  (CLECs),  Inter-exchange  Carriers ("IXCs")
and Original Equipment Manufacturers ("OEMs") with the ability to accelerate the
introduction of new products and services, to reduce costs and to enter into new
markets rapidly.

         VASP(TM)'s  applications are designed to administer,  operate,  control
and manage switching devices and network elements in the public carrier services
market. The Company believes that VASP(TM) provides  telecommunications carriers
with superior billing,  management and control  capabilities.  VASP(TM) has been
designed  to  be  integrated   with  any  carrier's   customer  care,   billing,
provisioning  and  network   management   applications.   VASP(TM)   accumulates
information about network events for each phone call and generates a Transaction
Detail Record ("TDR").  The TDR can be converted into the standard industry call
detail record or into customized  information  that allows service  providers to
bill innovatively (e.g.,  millisecond billing).  In addition,  service providers




                                       38
<PAGE>

can access their databases  containing customer  information and individual call
records in real-time to trouble  shoot  problems and identify  customer  calling
patterns.  This  information  can be  obtained by simple  dial-up  access from a
personal  computer,  as opposed to the current  network  process of  downloading
information  from each switch in the network,  which can take more than a day to
complete.  The carrier can use such  information  as a strategic  advantage  for
pricing and offering targeted product based upon real-time market feedback.  The
Company's software can also be used as a network surveillance monitoring device.
The  software  has the  ability  to  track  phone  calls  from  end-to-end  and,
therefore,  can  locate  the  specific  network  element  that may be  causing a
problem.  These  advantages,  coupled with the capability to provision  circuits
electronically, will significantly reduce carriers' operating costs.

         The Company expects that future releases of VASP(TM) will allow for the
replacement of the Class 4/tandem.  switch and Class 5/end-office  switch. Based
upon  engineering  studies,  the  Company  believes  that by using  Asynchronous
Transfer Mode ("ATM") and VASP(TM) in place of traditional  switch fabrics,  the
reduction  in  tandem  switching  investment  will  lower  the  overall  cost of
multi-city interconnections by 45% to 60%. The VASP(TM) open system architecture
is scalable  from small sizes up to hundreds of phone calls per second,  and its
underlying  hardware  platforms and control  center designs are selected to meet
the  operating  objectives  by  accumulating  no more than one hour of  downtime
during  each  twenty  year  period of  service  (99.999%  uptime  service  level
objective).  VASP(TM) is also  adaptable to other  transmission  mediums such as
Internet  Protocol ("IP"),  cable and wireless.  VASP(TM)  products and services
include the following:

         Virtual Class 4/Tandem. The Company expects that its software, combined
with an ATM switching  platform,  will be capable of replacing  the  traditional
Class 4/tandem  switch.  This capability  will enable data service  providers to
offer voice products over their  existing  networks.  VASP(TM), running on a Sun
Microsystems  server and controlling  ATM switches,  offers a 30% to 40% savings
over the cost of purchasing  and  installing  traditional  tandem  switches.  In
addition  TeleHub's  VASP(TM)  -based  software  solution offers other benefits,
including  cost  effective  scalability,   customization  to  specific  customer
requirements and applications, and faster introduction of new products.

         Local Switch Bypass. TTC is engineering  solutions to identify Internet
data and other  long-holding  time  calls  (e.g.,  voice  mail)  and route  them
directly to called parties,  thereby  bypassing  end-office and tandem switches.
The Company  expects this  technology to address  carriers'  growing  problem of
congestion at end-office and tandem switches caused by Internet  traffic.  TTC's
solution  allows  carriers to manage  existing  traffic  levels and flow without
purchasing additional switch capacity.

         Virtual  Class  5/End-Office  Switching.  TeleHub is in the  process of
enhancing its VASP(TM) solution to duplicate the basic  functionality of a Class
5/end-office  switch.  TeleHub  expects its virtual  Class 5 solution to provide
carriers with the capability to enter the local market with a voice product at a
fraction of the cost of buying and installing a conventional  Class 5/end-office
switch.  The same advantages offered by TeleHub's Class 4/tandem switch solution
apply   here  -  reduced   capital   expenditures,   customization   and  faster
time-to-market for new products.  As an example,  many CLECs have data Points of










                                       39
<PAGE>

Presence  ("POPs") which  currently  utilize ATM switches.  TeleHub  expects its
solution to allow CLECs to carry and switch voice traffic  using their  existing
ATM networks without purchasing Class 5/end-office switches.

         Virtual STP/SCP Signaling).  Signal Transfer Points ("STPs") and Signal
Control Points  ("SCPs") are key elements of the underlying  Signaling  System 7
("SS7") network.  Messages,  such as telephone number,  calling card validation,
800 number routing, and calling name delivery are transmitted to STPs that route
the  messages to the proper SCPs where call  processing  information  is stored.
Embodied  within the VASP(TM)  design today are both SCP and STP  functionality,
thereby allowing carriers to perform their own SS7 signaling, without purchasing
signaling  services or expensive  equipment.  VASP(TM) contains  translation and
routing  instructions  needed to deliver  advanced  network  services and can be
further  enhanced as new services or requirements  are identiRed.  The necessary
STP  functions  are also  incorporated  in the  VASP(TM)  design to  handle  the
signaling and management of "on-net"  traffic.  Conventional  STP is deployed in
VASP(TM) as an  interface  to other  carriers in the Public  Switched  Telephone
Network  ("PSTN")  and  as a  firewall  to  protect  both  parties'  proprietary
information from compromise.

         Mediated  Access  Services  ("MAS').  The  Telecommunications  Act  and
subsequent  FCC mandates  will  require  service  inter-operability  between the
various proprietary systems of existing  telecommunications  carriers. Local and
long  distance  carriers  and  their  current  software  vendors  are  therefore
expending significant design and software development resources trying to create
the inter- operability solutions that can be achieved through VASP(TM).  TeleHub
expects many carriers to select TeleHub as a service  supplier and VASP(TM) as a
standard product to integrate the various operating overlays.

         TeleHub  expects its MAS  capability to provide  neutral  "third-party"
access to service  management  system and  Operational  Support  system  ("OSS")
databases   throughout   the  industry.   Any  service   provider   (virtual  or
facilities-based)  will be able to  obtain  the key call  treatment  information
necessary to process  customer calls,  while the proprietary  information of the
database owner is protected from compromise. The first requirement for mediation
results from the FCC's  mandated LNP that requires the Regional  Bell  Operating
Companies  ("RBOCs") and GTE  Corporation  ("GTE") to permit their  customers to
switch to another  competing  Local  Exchange  Carrier  ("LEC") and still retain
their same  telephone  number.  The Company  believes its MAS will encourage the
LECs to offer unbundled local service  elements to other carriers as required by
the  Telecommunications  Act. Management believes this is currently the greatest
hurdle for the RBOCs to overcome in achieving  their long standing goal of entry
into the long distance business within their regions.

         Switched  Virtual  Circuit  ("SVC').  The  Company is in the process of
developing  an  SVC  product   expected  to  provide  carriers  with  a  cheaper
alternative to permanent virtual circuit (i.e., point-to-point) products offered
today.  The  advantage  of a SVC is that when the circuit is not  utilized,  the
capacity can be  allocated  for another  use. A permanent  virtual  circuit must
allocate  bandwidth to the user  regardless of whether there is traffic  flowing
over the circuit.

3.0 Committed TNS Feature Support

VASP 2.2 supports the hybrid call model,  including 600E and DS0 switching.  The
600E is not required in any way to complete a DS0 ATM call.

VASP 3.0 provides Q.2931 and DS0 switching  support.  The hybrid call model will
not be supported.

Support  for  the  current  TNS  architecture  including  the  DSC/Alcatel  600E
switching  elements  will be  maintained  in software up to VASP Release 2.2 for
TNS.

As a general policy, Newco will support backward VASP software  compatibility up
to two previous releases.  However, backward software compatibility between VASP
2.x and VASP 3.x releases will not be supported.

3.2      TNS Features in VASP(TM) Release 3.0

The following TNS features are committed for VASP(TM) Release 3.0:

VASP(TM) Software Version Monitoring

The ability to reliably  track and trace the  software  content of the  VASP(TM)
system will be supported through software version control.

Active  monitoring of software  version  status  across all  redundant  VASP(TM)
components  will be  supported  to ensure the same  software is loaded into each
redundant element.

On  detection  of a software  mismatch,  a system  maintenance  alarm  should be
raised.

Integrated Network Alarm Analysis

Network and  environmental  alarms must be collected and presented to the NCC in
real-time.  The  capability  to  maintain a history of alarms for  analysis  and
reporting will be supported. 
          o        In this case, real-time means within a reasonable  length  of
                   time to permit manual intervention if action is required.
          o        Alarm  reporting to NCC screens will be integrated with other
                   VASP(TM) displays, have color GUIs and text alarm 
                   presentation. The system will allow technicians  to 
                   acknowledge and selectively disable individual alarms.
          o        Alarm  histories will be maintained  for event  reporting and
                   analysis.  Analysis will be aided by time,  geographical  and
                   scope of impact relational tools.

          o 3.3.   TNS Feature Requests

          o 3.3.1. Selective Routing  Options  for  Operator  and  Calling  Card

          o 3.3.2. Least Cost Routing for international calls with 3rd party SS7
                   integration based on Trunk Route tariffing.

          o 3.3.3. Sub-carrier Identification Code Features

4.0  Reliability Model

4.1.    VASP(TM) EM Server Redundancy Controls
Under service affecting fault conditions, a system-initiated  failover should be
triggered  which  interrupts  normal  services  for  less  than 30  seconds  and
preserves  all  established  calls.  Newbridge  and Newco will work  together to
design and implement changes  to the  36170  and the VASP(TM) software  required
achieving this goal.

         4.1.1.  Requirements Details
          o        Automated detection of service impacting system fault
                   conditions
          o        When a fault is detected on active server unit:
                   --   System initiated switch of control to the standby 
                        VASP(TM) server unit
                   --   Normal call processing interrupted for less than 30
                        seconds
                   --   Calls in process (setup phase) are lost
                   --   Calls in progress(talking state) are preserved, 
                        including billing information
                   --   Appropriate loss of redundancy system alarms are raised
          o        When a fault is detected in the inactive unit:
                   --   Inactive unit is removed from normal operating state
                   --   Appropriate loss of redundancy system alarms are raised
          o        Sufficient call context will be shared between the active and
                   standby VASP(TM) servers to reliably maintain active (talking
                   calls) during the switch over phase.
          o        The fault detection system  must  prevent both VASP(TM)server
                   systems from being in the active state at the same time.
          o        The fault  detection  system must prevent the switch over of
                   control to the standby  VASP(TM)server if the synchronization
                   state  of  the EM  configuration  databases  is  unknown  or
                   mismatched.
          o        VASP(TM) will integrate the Newbridge  proxy  signaling API. 
                   This API will provide  uninterrupted  layer 2 protocol during
                   the  switch  over  phase,  maintaining  the established  call
                   connections.  Newbridge  will  cooperate  with  Newco  on the
                   design, early delivery, and test of the new API.
          o 
4.2.     Telco Environment Hardware Compliance
The VASP(TM) system will be available on a NEBS standard hardware platform.

4.2.1.   Requirements Details
          o        Typical NEBS compliance for VASP(TM) hardware
          o        Ability  to change the  following  hardware  modules  without
                   having to power cycle and reload the VASP(TM) system:
                   --   Disk drives
                   --   Redundant power supply
                   --   Newco will support the VASP(TM) software on a NEBS
                        compliant fault tolerant platform that can perform hot 
                        swapping.

          o        Newco  agrees to prepare the call  processing  and  signaling
                   architecture  to  facilitate   deployment  of  overlap  digit
                   outpulsing in 2000. 6.4. Billing Formats
          o        Reasonable  support will be provided to support telco billing
                   format   requirements  such  as  call  detail  records  (CDR)
                   enabling 1999 deployment

7.       Development Capacity Headroom

Newco  agrees to plan for the 1999  delivery  of  additional  VASP(TM)  features
necessary to win and maintain the key reference telco accounts described in this
agreement.  Anticipated feature requests may include (but are not limited to):
          o        Additional  translation and routing  features o Basic network
                   management route controls
          o        OSS integration and support o Billing format alterations
