           STARTEC GLOBAL COMMUNICATIONS CORPORATION AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)


1.   BUSINESS DESCRIPTION:

ORGANIZATION

     Startec Global Communications Corporation (the "Company", formerly Startec,
Inc.),  is a  Maryland  corporation  founded  in 1989 to  provide  long-distance
telephone services. The Company currently offers  U.S.-originated  long-distance
service to residential and carrier customers through a flexible network of owned
and leased transmission facilities, resale arrangements, and foreign termination
arrangements. The Company's marketing targets specific ethnic residential market
segments  in  the  United   States  that  are  most  likely  to  seek   low-cost
international   long-distance  service  to  specific  and  identifiable  country
markets. The Company is headquartered in Bethesda, Maryland.

REORGANIZATION

     The  Company's  board  of  directors  and  stockholders   have  approved  a
reorganization  pursuant  to which the  Company's  corporate  structure  will be
realigned  to  that  of  a  publicly  traded  Delaware  holding   company.   The
reorganization  will  consist  of  the  transfer  of  substantially  all  of the
Company's assets into a newly  incorporated  Delaware  subsidiary company (" New
Parent"),  and the subsequent transfer of those assets to multiple  subsidiaries
of the New Parent. After such transfer, the Company will be merged with and into
the New Parent.  As of June 30, 1998,  the New Parent and its  subsidiaries  had
been  formed,  but no transfer of assets had been made.  The  reorganization  is
expected to be completed  during the fourth quarter ended December 1998 and will
not have an impact on the consolidated financial statements of the Company.

RISKS AND OTHER IMPORTANT FACTORS

     The Company is subject to various risks in connection with the operation of
its  business.  These  risks  include,  but are not limited  to,  dependence  on
operating  agreements with foreign partners,  significant foreign and U.S.-based
customers and  suppliers,  availability  of  transmission  facilities,  U.S. and
foreign   regulations,   international   economic  and  political   instability,
dependence on effective billing and information systems, customer attrition, and
rapid technological  change. Many of the Company's competitors are significantly
larger  and have  substantially  greater  financial,  technical,  and  marketing
resources  than the Company;  employ  larger  networks and control  transmission
lines; offer a broader portfolio of services; have stronger name recognition and
loyalty;  and  have  long-standing   relationships  with  the  Company's  target
customers.  In addition,  many of the Company's  competitors  enjoy economies of
scale that can result in a lower cost  structure  for  transmission  and related
costs, which could cause significant  pricing pressures within the long-distance
telecommunications  industry.  If  the  Company's  competitors  were  to  devote
significant additional resources to the provision of international long-distance
services  to  the  Company's  target  customer  base,  the  Company's  business,
financial  condition,  and results of operations  could be materially  adversely
affected.

     In the United States,  the Federal  Communications  Commission  ("FCC") and
relevant  state  Public  Service  Commissions  have the  authority  to  regulate
interstate and intrastate  telephone service rates,  respectively,  ownership of
transmission facilities,  and the terms and conditions under which the Company's
services  are  provided.   Legislation  that  substantially   revised  the  U.S.
Communications  Act of 1934  was  signed  into law on  February  8,  1997.  This
legislation  has specific  guidelines  under which the Regional  Bell  Operating
Companies ("RBOCs") can provide  long-distance  services,  which will permit the
RBOCs to  compete  with the  Company in  providing  domestic  and  international
long-distance  services.  Further,  the legislation,  among other things,  opens
local service markets to competition  from any entity  (including  long-distance
carriers, such as AT&T, cable television companies and utilities).

     Because  the  legislation   opens  the  Company's   markets  to  additional
competition,  particularly  from the RBOCs, the Company's ability to compete may
be  adversely  affected.   Moreover,  certain  Federal  and  other  governmental
regulations  may be amended or modified,  and any such amendment or modification
could have  material  adverse  effects  on the  Company's  business,  results of
operations, and financial condition.

2.   SIGNIFICANT ACCOUNTING PRINCIPLES:

GENERAL

     In  addition to the  principles  identified  below,  Note 2 of the Notes to
Financial Statements,  as set forth in the Company's Annual Report on Form 10-K,
summarizes the Company's significant accounting principles.

USE OF ESTIMATES IN PREPARATION OF FINANCIAL STATEMENTS

     The  preparation  of financial  statements  in  conformity  with  generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that  affect the  reported  amounts of assets and  liabilities  and
disclosure of  contingent  assets and  liabilities  at the date of the financial
statements  and the  reported  amounts  of  revenues  and  expenses  during  the
reporting period. Actual results could differ from those estimates.

REVENUE  RECOGNITION

     Revenues  for   telecommunication   services   provided  to  customers  are
recognized  as services are  rendered,  net of an allowance for revenue that the
Company  estimates  will  ultimately  not be  realized.  The  Company  routinely
evaluates its requirements for allowance for doubtful accounts.  Upon receipt of
favorable  collection  data,  the Company  reduced its  allowance  for  doubtful
accounts by approximately  $337,000 during the three-month period ended June 30,
1998.  Revenues  for  return  traffic  received  according  to the  terms of the
Company's  operating  agreements  with its foreign  partners are  recognized  as
revenue as the return traffic is received and processed.

BASIS OF PREPARATION OF INTERIM FINANCIAL INFORMATION

     The  financial  statements  included  herein  are  unaudited  and have been
prepared  pursuant to the rules and  regulations  of the Securities and Exchange
Commission (the "SEC").  Certain information and footnote  disclosures  normally
included in financial  statements prepared in accordance with generally accepted
accounting  principles have been condensed or omitted pursuant to such rules and
regulations.  In the opinion of management, the financial statements reflect all
adjustments  (of a normal and  recurring  nature) which are necessary to present
fairly the  financial  position,  results of  operations  and cash flows for the
interim  periods.  These  unaudited  financial  statements  should  be  read  in
conjunction with the audited financial statements and notes thereto for the year
ended  December 31, 1997,  included in the Company's  most recently filed Annual
Report on Form 10-K.  The results for the six months ended June 30, 1998 are not
necessarily  indicative  of the results that may be expected for the year ending
December 31, 1998.

CONCENTRATIONS OF RISK

     Financial   instruments   that   potentially   subject  the  Company  to  a
concentration  of credit  risk are  accounts  receivable.  Residential  accounts
receivable  consist  of  individually  small  amounts  due  from  geographically
dispersed  customers.  Carrier accounts  receivable  represent  amounts due from
long-distance  carriers.  The Company's allowance for doubtful accounts is based
on current  market  conditions.  The Company's  four largest  carrier  customers
represented  approximately 44 and 31 percent of gross accounts  receivable as of
December 31, 1997, and June 30, 1998,  respectively.  The Company's five largest
carrier customers  represented  approximately 33 percent of net revenues for the
six-month period ended June 30, 1998.  Purchases from the five largest suppliers
represented  approximately  38 percent of cost of services for six-month  period
ended June 30, 1998.

NET INCOME PER SHARE

     In 1997, the Financial  Accounting  Standards Board released  Statement No.
128, "Earnings Per Share." Statement 128 requires dual presentation of basic and
diluted  earnings per share on the face of the statement of  operations  for all
periods presented. Basic earnings per share excludes dilution and is computed by
dividing income available to common stockholders by the weighted-average  number
of common shares outstanding for the period. Diluted earnings per share reflects
the potential  dilution  that could occur if  securities  or other  contracts to
issue common stock were  exercised or converted into common stock or resulted in
the  issuance of common  stock that then  shared in the  earnings of the entity.
Weighted average common and equivalent share amounts are derived as follows:

3.   SENIOR NOTES AND WARRANTS OFFERING:

     In May 1998, the Company completed the placement of $160 million 12% senior
notes due 2008 and  warrants to purchase  200,226  shares of common  stock at an
exercise  price of $24.20 per share.  This  placement  yielded  net  proceeds of
approximately  $155  million,  of which  approximately  $52  million was used to
purchase U.S.  Government  obligations which have been pledged to fund the first
six interest  payments due on the senior notes,  and the remainder of which will
be used to expand and develop the Company's network.  The network expansion will
include the purchase of switches and compression equipment, acquisition of fiber
optic cable  facilities,  and investment in and  acquisition of satellite  earth
stations.  The senior  notes are recorded at a discount of $2.1 million to their
face amount to reflect the value  attributed  to warrants.  The senior notes are
unsecured and require semi annual interest payments beginning November 15, 1998.
The senior notes and warrants have certain registration rights.

4.   STOCK OPTION PLAN AMENDMENT:

     In July 1998 the stockholders approved an amendment to the 1997 Performance
Incentive  Plan to increase the number of shares  available  for  issuance  from
750,000 shares to 18.5 percent of the outstanding shares of the Company,  and to
revise  the  plan in  order  to  continue  to  qualify  awards  thereunder  as "
performance - based" compensation not subject to the limitation on deductibility
under Section 162(m) of the Internal Revenue Code.

5.   RELATED PARTY TRANSACTION:

     During the second  quarter of 1998,  the company  advanced an  aggregate of
approximately  $737,000 to certain of its employees and officers. The loans bear
interest at a rate of 7.87% per year,  and are due and  payable on December  31,
1998. The loans are included in other current assets in the accompanying balance
sheet.

6.   COMMITMENTS AND CONTINGENCIES:

LITIGATION

     Certain  claims have been  asserted  against the Company.  In  management's
opinion,  resolution  of these  matters  will not have a material  impact on the
Company's business,  financial condition or results of operations,  and adequate
provision for any potential losses has been made in the  accompanying  financial
statements.

7.   RECENTLY ADOPTED ACCOUNTING PRONOUNCEMENTS:

     In June 1997, the Financial Accounting Standards Board issued SFAS No. 130,
"Reporting  Comprehensive Income," and SFAS No. 131, "Disclosures about Segments
of an Enterprise and Related Information."

     SFAS No. 130 requires  "comprehensive  income" and the components of "other
comprehensive  income," to be reported in the financial  statements and/or notes
thereto.  As the Company  did not have any  components  of "other  comprehensive
income" net income is the same as "total  comprehensive  income" for all periods
presented.

     SFAS No. 131  requires  entities  to  disclose  financial  and  descriptive
information  about  its  reportable  operating  segments.  It  also  establishes
standards for related disclosures about products and services, geographic areas,
and  major  customers.  SFAS  No.  131 is not  required  for  interim  financial
reporting  purposes  during 1998. The Company is in the process of assessing the
additional disclosures, if any, required by SFAS No. 131. However, such adoption
will not impact the Company's results of operations or financial position, since
it relates only to disclosures.

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

     The  following  discussion  and  analysis of the  financial  condition  and
results  of  operations  should  be  read  in  conjunction  with  the  financial
statements,  related notes, and other detailed information included elsewhere in
this Quarterly  Report on Form 10-Q.  This  Quarterly  Report  contains  certain
forward-looking  statements  within the meaning of Section 27A of the Securities
Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934,
as amended.  Forward-looking  statements  are statements  other than  historical
information or statements of current condition.  Some forward looking statements
may be identified by use of such terms as "believes", "anticipates",  "intends",
or "expects".  These forward-looking  statements relate to plans, objectives and
expectations  of the  Company for future  operations.  In light of the risks and
uncertainties inherent in all such projected operation matters, the inclusion of
forward-looking statements in this report should not be regarded as


                                       8

<PAGE>



a representation by the company or any other person that the objectives or plans
of the  Company  will  be  achieved  or  that  any of  the  Company's  operating
expectations will be realized.  The Company's revenues and results of operations
are difficult to forecast and could differ  materially  from those  projected in
the forward-looking  statements  contained in this report as a result of certain
factors including,  but not limited to, dependence on operating  agreements with
foreign partners,  significant  foreign and U.S.-based  customers and suppliers,
availability  of  transmission   facilities,   U.S.  and  foreign   regulations,
international  economic  and  political  instability,  dependence  on  effective
billing and information  systems,  customer  attrition,  and rapid technological
change.  These  factors  should  not  be  considered  exhaustive;   the  Company
undertakes no obligation to release publicly the results of any future revisions
it may make to  forward-looking  statements to reflect  events or  circumstances
after the date hereof or to reflect the occurrence of unanticipated events.

     Results of Operations

     The following  table sets  forth-certain  financial data as a percentage of
net revenues for the periods indicated.

</TABLE>


THREE MONTH PERIOD ENDED JUNE 30, 1998 COMPARED TO THREE MONTH PERIOD ENDED
JUNE 30, 1997

     Net  Revenues.  Net  revenues  for the three  months  ended  June 30,  1998
increased  approximately  $17.0 million or 103.3 percent, to approximately $33.5
million from $16.5 million for the three months ended June 30, 1997. Residential
revenue increased in comparative  periods by approximately $7.1 million or 120.3
percent,  to approximately  $13.0 million for the three-month  period ended June
30, 1998 from  approximately  $5.9  million in the second  quarter of 1997.  The
increase  in  residential  revenue  is  due to an  increase  in  the  number  of
residential  customers  to over  93,500 as of June 30,  1998 from  approximately
43,700 as of June 1997.  Carrier revenue for the  three-month  period ended June
30, 1998 increased approximately $10.0 million or 95.2 percent, to approximately
$20.5 million from  approximately  $10.5 million for the second quarter of 1997.
The  increase  in carrier  revenues  is due to the  execution  of the  Company's
strategy to optimize its capacity on its facilities, which has resulted in sales
to new carrier customers and increased sales to existing carrier customers.

     Gross Margin.  Gross margin increased by approximately $2.6 million to $4.6
million for the three-month period ended June 30, 1998 from $2.0 million for the
three-month period ended June 30, 1997. Gross margin improved as a percentage of
net revenues for the three-month period ended June 30, 1998 to 13.8 percent from
12 percent for the three-month  period ended June 30, 1997. Gross margin for the
three-month  period  ended June 30,  1998  improved  due to an  increase  in the
traffic originated on the Company's own network and improved termination costs.

     General and  Administrative.  General and  administrative  expenses for the
three-month  period ended June 30, 1998 increased 223.1 percent to approximately
$4.2 million from $1.3 million for the  three-month  period ended June 30, 1997.
As a percentage of net revenues,  general and administrative  expenses increased
to 12.4 percent from 8.0 percent for the  respective  periods.  The increase was
primarily  due to an  increase in  personnel  to 266 at June 30, 1998 from 72 at
June 30, 1997, and to a lesser extent, an increase in billing processing fees.

     Selling and Marketing.  Selling and marketing  expenses for the three-month
period ended June 30, 1998 increased 444.6 percent to approximately $1.1 million
from approximately $201,000 for the three-month period ended June 30, 1997. As a
percentage of net revenues,


                                       9

<PAGE>
selling and marketing expenses increased to 3.3 percent from 1.2 percent for the
respective  periods.  The increase is primarily due to the Company's  efforts to
market to new, and increased efforts to market to existing, customer groups.

     Depreciation and Amortization.  Depreciation and amortization  expenses for
the three-month  period ended June 30, 1998 increased to approximately  $524,000
from $118,000 for the three-month  period ended June 30, 1997,  primarily due to
increases  in  capital  expenditures  pursuant  to  the  Company's  strategy  of
expanding its network infrastructure.

     Interest.  Interest  expense  for  three-month  period  ended June 30, 1998
increased to approximately $2.4 million from $135,000 for the three-month period
ended June 30, 1997, as a result of a senior notes offering by the Company.  The
Company  also  recorded  interest  income  of  approximately  $943,000  for  the
three-month  period  ended June 30, 1998 as a result of  investing  the offering
proceeds.

     Net Loss.  Net loss was  approximately  $2.7  million  for the  three-month
period ended June 30, 1998 as compared to net income of  approximately  $214,000
for the three-month period ended June 30, 1997.

SIX MONTH PERIOD ENDED JUNE 30, 1998 COMPARED TO SIX MONTH PERIOD ENDED
JUNE 30, 1997

     Net Revenues. Net revenues for the six months ended June 30, 1998 increased
approximately  $34.6 million or 120.1 percent,  to  approximately  $63.4 million
from $28.8 million for the six months ended June 30, 1997.  Residential  revenue
increased  in  comparative  periods  by  approximately  $13.7  million  or 130.5
percent,  to approximately  $24.2 million for the six months ended June 30, 1998
from  approximately  $10.5  million for the six months ended June 30, 1997.  The
increase  in  residential  revenue  is  due to an  increase  in  the  number  of
residential  customers to over 93,500 as of June 1998 from approximately  43,700
as of June 1997.  Carrier  revenue for the six-month  period ended June 30, 1998
increased  approximately  $20.9 million or 114.2 percent, to approximately $39.2
million from approximately $18.3 million for the six months ended June 30, 1997.
The  increase  in carrier  revenues  is due to the  execution  of the  Company's
strategy to optimize its capacity on its facilities, which has resulted in sales
to new carrier customers and increased sales to existing carrier customers.

     Gross Margin.  Gross margin increased by approximately $5.3 million to $8.9
million for the six-month  period  ended June 30, 1998 from $3.6 million for the
six-month period ended June 30, 1997.  Gross margin  improved as a percentage of
net revenues for the  six-month  period ended June 30, 1998 to 14.0 percent from
12.4 percent for the six-month  period ended June 30, 1997. Gross margin for the
six-month  period ended June 30, 1998 improved due to an increase in the traffic
originated on the Company's own network,  improved  termination  costs,  and the
favorable  adjustment  to the  allowance  for  doubtful  accounts  in the second
quarter of 1998.

     General and  Administrative.  General and  administrative  expenses for the
six-month period ended June 30, 1998 increased 176 percent to approximately $6.9
million from $2.5  million for the  six-month  period ended June 30, 1997.  As a
percentage of net revenues,  general and  administrative  expenses  increased to
10.8  percent  from 8.5 percent for the  respective  periods.  The  increase was
primarily  due to an  increase in  personnel  to 266 at June 30, 1998 from 72 at
June 30, 1997, and to a lesser extent, an increase in billing processing fees.

     Selling and  Marketing.  Selling and  marketing  expenses for the six-month
period ended June 30, 1998 increased 488.2 percent to approximately $1.8 million
from  approximately  $306,000 for the six-month period ended June 30, 1997. As a
percentage of net  revenues,  selling and  marketing  expenses  increased to 2.8
percent from 1.1 percent for the respective  periods.  The increase is primarily
due to the Company's  efforts to market to new, and increased  efforts to market
to existing, customer groups.

     Depreciation and Amortization.  Depreciation and amortization  expenses for
the six month period ended June 30, 1998  increased  to  approximately  $708,000
from  $214,000 for the  six-month  period ended June 30, 1997,  primarily due to
increases  in  capital  expenditures  pursuant  to  the  Company's  strategy  of
expanding its network infrastructure.

     Interest.  Interest  expense for the  six-month  period ended June 30, 1998
increased to  approximately  $2.6 million from $252,000 for the six-month period
ended June 30, 1997, as a result of a senior notes offering by the Company.  The
Company also  recorded  interest  income of  approximately  $1.3 million for the
six-month  period  ended June 30,  1998 as a result of  investing  the  offering
proceeds.

     Net Loss. Net loss was approximately  $1.8 million for the six-month period
ended June 30, 1998 as compared to a net income of approximately $351,000 in for
the six-month period ended June 30, 1997.

     Liquidity and Capital Resources

     The  Company's  liquidity  requirements  arise from cash used in  operating
activities,   purchases  of  network  equipment,  and  payments  on  outstanding
indebtedness.  Prior to the  completion  of its  initial  public  offering,  the
Company financed its activities through capital lease financings,  notes payable
from  individuals,  a  credit  arrangement  with a third  party  company  (since
terminated) and a secured revolving line of credit  arrangement with a bank. The
credit facility provides for maximum  borrowings of the lesser of $15 million or
85% of eligible accounts receivable,  as defined, until maturity on December 31,
1999.  The Company  may elect to pay  quarterly  interest  payments at the prime
rate, plus 2%, or the adjusted LIBOR, plus 4%. The credit facility is secured by
substantially  all of the Company's  assets.  The credit  facility  recently was
amended in connection  with the senior notes  offering and  Reorganization.  The
amended credit  facility has certain key financial  covenants that apply only if
the Company attempts to borrow.  The Company is currently not in compliance with
these  covenants and therefore,  would be unable to borrow any amounts under the
credit facility.


                                       10

     The Company  completed its initial public  offering of 3,277,500  shares of
its common stock in October 1997, the net proceeds of which (after  underwriting
discounts,  commissions and other professional fees) approximated $35.0 million.
The Company used a portion of the net proceeds to acquire cable  facilities  and
switching,  compression and related telecommunications  equipment. Proceeds were
also used for  marketing  programs,  to pay down  amounts  due under the  credit
facility and for working capital and general corporate purposes.

     In May 1998, the Company  completed the placement of $160 million aggregate
principal  amount of 12% senior notes due 2008 and warrants to purchase  200,226
shares of common stock at an exercise price of $24.20 per share.  This placement
yielded net proceeds of approximately $155 million,  of which  approximately $52
million was used to purchase U.S. Government obligations which have been pledged
to fund the  first  six  interest  payments  due on the  senior  notes,  and the
remainder of which will be used to expand and develop the Company's network. The
network  expansion  will  include  the  purchase  of  switches  and  compression
equipment,  acquisition of fiber optic cable  facilities,  and investment in and
acquisition  of satellite  earth  stations.  The senior notes are  unsecured and
require semi annual interest  payments  beginning  November 15, 1998. The senior
notes and warrants have certain registration rights.

     The Company's cash and cash  equivalents  increased to  approximately  $120
million at June 30, 1998 from approximately  $26.1 million at December 31, 1997.
Net cash used for operating  activities was  approximately  $2.3 million for the
six-month  period  ended June 30,  1998,  as  compared  to net cash  provided by
operating  activities of $514,000 for the six-month  period ended June 30, 1997.
The decrease in cash from  operations  for the  six-month  period ended June 30,
1998 was  primarily  the  result  of the net loss and an  increase  in  accounts
receivable,  which was  partially  offset by increase  in  accounts  payable and
accrued expenses.

     Net cash used in investing  activities was  approximately  $5.7 million and
$184,000 for the six months ended June 30, 1998 and 1997, respectively. Net cash
used in  investing  activities  for the six  months  ended  June  30,  1998  was
primarily  related  to capital  expenditures  to expand  the  Company's  network
infrastructure.

     Net cash provided by financing  activities was  approximately  $102 million
and $1.6 million for the six months ended June 30, 1998 and 1997,  respectively.
The cash provided by financing activities for the six months ended June 30, 1998
primarily resulted from the senior notes offering.

     As a result of completing  the senior note  offering,  the Company  expects
that it will incur  negative  EBITDA and  significant  operating  losses and net
losses for the next several years as it incurs  additional costs associated with
the development  and expansion of its marketing  programs and its entry into new
markets, the introduction of new telecommunications services, and as a result of
the interest  expense  associated with its financing  activities.  The Company's
principal  cash  requirements  will be for capital  expenditures  related to the
Company's  network  development  plan   and for interest  payments on the senior
notes.  Approximately  $52 million of the net  proceeds of the senior  notes was
used to purchase the pledged securities,  which will assure holders of the notes
that they will receive all  scheduled  cash  interest  payments  through May 15,
2001. The Company may be required to obtain additional financing in order to pay
interest in the senior  notes after May 15, 2001 and to repay the notes at their
maturity.

     The Company's business strategy contemplates aggregate capital expenditures
(including  capital  expenditures,  working capital and other general  corporate
purposes) of  approximately  $165.8 million  through  December 31, 2000. Of such
amount, the Company intends to use approximately  $152.8 million to fund capital
expenditures to expand and develop the Company's network (including $5.8 million
which has already been allocated to purchase the Los Angeles switch).

     During  1998,  the  Company  plans to install a new  international  gateway
switch in Los Angeles and to redeploy its  Washington,  D.C.  switch to Chicago,
where it will serve as a domestic  switch.  In  addition,  the Company  plans to
acquire (i) six additional  switches  during 1998 to be deployed during 1998 and
early 1999 in Chile,  France,  Germany,  Japan,  the  Netherlands and the United
Kingdom;  (ii) nine  additional  switches during 1999 to be deployed during 1999
and early 2000 in Australia,  Belgium,  Canada (two), Hong Kong, Italy,  Mexico,
Switzerland  and  Uganda   and  (iii)  four  additional  switches  in 2000 to be
deployed during 2000 and early 2001 in Argentina,  Brazil,  India and Singapore.
The  Company  also  intends to invest in domestic  land-based  fiber optic cable
facilities  linking  the East  Coast and West Coast of the  United  States,  and
undersea fiber optic transmission  facilities linking North America with Europe,
the Pacific Rim, Asia and Latin America.  Moreover,  the Company plans to invest
in or acquire two satellite  earth stations  during 1998 and 1999.  From time to
time, however,  the Company is presented with marketing  opportunities which may
result  in  the  relocation,  redeployment,  or  alternative  deployment  of the
Company's switches, points-of-presence, and other telecommunications equipment.

     After  taking into  account the net proceeds to the Company from the senior
notes  offering and the  purchase of the pledged  securities  together  with the
Company's cash on hand and anticipated cash from operations, the Company expects
that it will  need  approximately  $40.0  million  of  additional  financing  to
complete its capital spending plan through the end of 2000. Although the Company
believes  that  it  should  be able  to  obtain  this  required  financing  from
traditional sources, such as bank lenders,  asset-based  financiers or equipment
vendors,  there can be no assurance  the Company will be successful in arranging
such  financing on terms its  considers  acceptable or at all. In the event that
the  Company is unable to obtain  additional  financing,  it will be required to
limit or curtail its expansion plans.
<PAGE>

     The  Company  regularly  reviews  opportunities  to  further  its  business
strategy  through  strategic  alliances with,  investment in, or acquisitions of
businesses  that it believes  are  complementary  to the  Company's  current and
planned operations. The Company, however, has no present commitments, agreements
or understandings with respect to any particular strategic alliance, acquisition
or  investment.  The  Company's  ability to consummate  strategic  alliances and
acquisitions,  and to make investments that may be of strategic  significance to
the Company,  may require the Company to obtain  additional  debt and/or  equity
financing.  There can be no  assurance  that the Company will be  successful  in
arranging such financing on terms it considers acceptable or at all.


                                       11

     The  implementation  of  the  Company's   strategic  plan,   including  the
development and expansion of its network facilities,  expansion of its marketing
programs,  and funding of  operating  losses and  working  capital  needs,  will
require significant investment. The Company expects that the net proceeds of the
senior notes offering  together with cash on hand and cash flow from operations,
will  provide the Company  with  sufficient  capital to fund  currently  planned
capital  expenditures  and anticipated  operating  losses through the end of the
first  quarter  2000.  There can be no assurance  that the Company will not need
additional financing sooner than currently anticipated.  The need for additional
financing depends on a variety of factors,  including the rate and extent of the
Company's  expansion  and new markets,  the cost of an  investment in additional
switching and transmission facilities and ownership rights in fiber optic cable,
the  incurrence of costs to support the  introduction  of additional or enhanced
services,  and increased sales and marketing expenses. In addition,  the Company
may need additional financing to fund unanticipated  working capital needs or to
take advantage of unanticipated business opportunities,  including acquisitions,
investments or strategic  alliances.  The amount of the Company's  actual future
capital  requirements also will depend upon many factors that are not within the
Company's  control,  including  competitive  conditions  and regulatory or other
government  actions. In the event that the Company's plans or assumptions change
or prove to be  inaccurate  or the net proceeds of this senior  notes  offering,
together  with  cash  on  hand  and  internally  generated  funds,  prove  to be
insufficient to fund the Company's  growth and  operations,  then some or all of
the Company's development and expansion plans could be delayed or abandoned,  or
the Company may be required to seek additional  financing or to sell assets,  to
the extent permitted by the terms of the senior notes.

     The  Company  may seek to raise  such  additional  capital  from  public or
private equity or debt sources.  There can be no assurance that the Company will
obtain additional financing or, if obtained,  that it will be able to do so on a
timely basis or on terms  favorable  to the  Company.  If the Company is able to
raise  additional  funds through the  incurrence of debt, it would likely become
subject to additional  restrictive  financial  covenants.  In the event that the
Company is unable to obtain such additional  capital or is unable to obtain such
additional  capital on acceptable  terms,  the Company may be required to reduce
the scope of its expansion, which could adversely affect the Company's business,
financial  condition and results of  operations,  its ability to compete and its
ability to meet its obligations under the senior notes.

     Although  the  Company  intends to  implement  the  capital  spending  plan
described above, it is possible that  unanticipated  business  opportunities may
arise which the  Company's  management  may conclude  are more  favorable to the
long-term  prospects  of the  Company  than those  contemplated  by the  current
capital  spending  plan.  Management  will have  significant  discretion  in its
decisions with respect to when and how to utilize the proceeds of the Offering.

     The Company has accrued  approximately $2.1 million as of June 30, 1998 for
disputed vendor  obligations  asserted by one of the Company's  foreign carriers
for  minutes  processed  in excess of the  minutes  reflected  on the  Company's
records.  If the Company  prevails in its  disputes,  these  amounts or portions
thereof would be credited to operations in the period of resolution. Conversely,
if the  Company  does not  prevail in its  disputes,  these  amounts or portions
thereof may be paid in cash.

     The  Company's  management  is currently  in the process of  assessing  the
nature and extent of the potential  impact of the Year 2000 issue on its systems
and applications,  including its billing,  credit and call tracking systems, and
intends  to take steps to  prevent  failures  in its  systems  and  applications
relating to Year 2000.  Although  many of the  Company's  operating  systems are
relatively  new and have  been  certified  to the  Company  as being  Year  2000
compliant,  there can be no  assurance  that the  Company's  systems will not be
adversely  affected by the Year 2000 issue.  In addition,  computers used by the
Company's  vendors  providing  services to the Company or computers  used by the
Company's  customers that interface with the Company's computer systems may have
Year 2000  problems,  any of which may  adversely  affect  the  ability of those
vendors to provide  services  to the  Company,  or in the case of the  Company's
carrier customers, to make payments to the Company. If any of such systems fails
or experiences processing errors, such failures or errors may disrupt or corrupt
the  Company's  systems.  The Company is in the initial  stages of verifying the
Year 2000  compliance  efforts of the third  parties  with  which the  Company's
computer  systems  interface.  Although  management  has not yet  finalized  its
analysis,  it does not expect that the costs to  properly  address the Year 2000
issue will have a  material  adverse  effect on its  results  of  operations  or
financial  position.  Failure of any of the Company's systems or applications or
the  failure,  or errors in,  the  computer  systems  of its  vendors or carrier
customers could materially  adversely affect the Company's  business,  financial
condition and results of operations.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

     This requirement is not currently applicable to the Company.


PART II - OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

     The Company is from time to time involved in  litigation  incidental to the
conduct of its  business.  The Company is not part to any lawsuit or  proceeding
which, in the opinion of management,  is likely to have material  adverse effect
on the Company's business, financial condition or results of operations.

ITEM 2. CHANGES IN SECURITIES

     On May 21, 1998, the Company issued 160,000 Units (the "Units")  consisting
of  $160,000,000  aggregate  principal  amount  of 12%  Senior  Notes  due  2008
("Notes") and warrants  ("Warrants")  to purchase an aggregate of 200,226 shares
of its Common Stock (the  "Warrant  Shares").  Each Unit  consists of (i) $1,000
principal amount of Notes and (ii) a Warrant to purchase 1.25141 Warrant Shares.
The Units were issued and sold by the Company to Lehman Brothers Inc.,  Goldman,
Sachs & Co. and ING Baring (U.S.) Securities,  Inc. (collectively,  the "Initial
Purchasers") in a transaction  exempt from the registration  requirements of the
Securities  Act of 1933, as amended (the  "Securities  Act") pursuant to Section
4(2) thereof and subsequently  resold by the Initial Purchasers pursuant to Rule
144A and Regulation S.

     Each Warrant,  when  exercised,  will entitle the holder thereof to receive
1.25141 fully paid and  non-assessable  Warrant  Shares at an exercise  price of
$24.20 per share (the  "Exercise  Price").  The Exercise Price and the number of
shares of Common Stock  issuable  upon exercise of a Warrant are both subject to
adjustment in certain circumstances. The Warrants are exercisable to purchase an
aggregate of 200,226  Warrant  Shares  representing  (on a fully diluted  basis,
assuming all options,  warrants and other stock rights outstanding are exercised
on the date of this  Prospectus)  approximately  2.0% of the  shares  of  Common
Stock. The Warrants expire by their terms on May 15, 2008.

                  INDENTURE,  dated as of May 21, 1998,  between  STARTEC GLOBAL
COMMUNICATIONS  CORPORATION, a corporation duly organized and existing under the
laws of the  State  of  Maryland  (herein  called  the  "Company"),  having  its
principal office at 10411 Motor City Drive, Suite 301, Bethesda, Maryland 20817,
as issuer,  and First Union  National Bank, a duly  organized  national  banking
association  existing  under the laws of the  United  States,  as  Trustee  (the
"Trustee").

                             RECITALS OF THE COMPANY

                  The Company has duly authorized the issuance of its 12% Senior
Notes due 2008 (the "Initial  Notes") and its 12% Series A Senior Notes due 2008
(the "Exchange  Notes" and,  together with the Initial Notes,  the "Notes"),  of
substantially  the  tenor and  amount  hereinafter  set  forth,  and to  provide
therefor,  the Company has duly  authorized  the  execution and delivery of this
Indenture.

                  Upon  the  issuance  of  Exchange   Notes,   if  any,  or  the
effectiveness  of the Shelf  Registration  Statement (as defined  herein),  this
Indenture will be subject to the provisions of the Trust  Indenture Act that are
required to be part of this Indenture and shall,  to the extent  applicable,  be
governed by such provisions.

                  The Notes are initially being issued, and until the Separation
Date must be traded, as units together with warrants to purchase common stock of
the Company.  Each unit will consist of $1,000  principal  amount of Notes and a
warrant  (collectively,  the  "Warrants")  to purchase  1.25141 shares of common
stock of the  Company.  The  Warrants  will be issued  pursuant  to the  Warrant
Agreement.

                  All things  necessary  have been done to make the Notes,  when
executed by the Company  and  authenticated  and  delivered  hereunder  and duly
issued by the  Company,  the valid  obligations  of the Company and to make this
Indenture a valid  agreement of the Company,  in  accordance  with their and its
terms.

                  NOW, THEREFORE, THIS INDENTURE WITNESSETH:

                  For and in  consideration  of the premises and the purchase of
the Notes by the Holders thereof,  it is mutually covenanted and agreed, for the
equal and proportionate benefit of all Holders of the Notes, as follows:

request, demand, authorization, direction, notice, consent, waiver or other Act,

address as it appears in the Register,  not later than the latest date,  and not
earlier than the earliest date, prescribed for the giving of such notice. In any
case where notice to Holders is given by mail,  neither the failure to mail such
notice,  nor any defect in any notice so mailed,  to any particular Holder shall
affect the sufficiency of such notice with respect to other Holders.  Any notice
mailed to a Holder in the manner herein prescribed shall be conclusively  deemed
to have been  received  by such  Holder,  whether  or not such  Holder  actually
receives such notice.  Where this  Indenture  provides for notice in any manner,
such  notice may be waived in writing by the  Person  entitled  to receive  such
notice,  either  before  or  after  the  event,  and  such  waiver  shall be the
equivalent of such notice.  Waivers of notice by Holders shall be filed with the
Trustee,  but such filing shall not be a condition  precedent to the validity of
any action taken in reliance upon such waiver.

                  In case by reason of the  suspension of or  irregularities  in
regular mail service or by reason of any other cause, it shall be  impracticable
to mail notice of any event to Holders  when such notice is required to be given
pursuant  to any  provision  of this  Indenture,  then any manner of giving such
notice  as  shall  be  satisfactory  to the  Trustee  shall  be  deemed  to be a
sufficient giving of such notice for every purpose hereunder.

                  SECTION 107.  Effect of Headings and Table of Contents.

                  The  Article  and  Section  headings  herein  and the Table of
Contents are for convenience only and shall not affect the construction hereof.

                  SECTION 108.  Successors and Assigns.

                  All covenants and agreements  made by the Company set forth in
this Indenture  shall bind its  successors and assigns,  whether so expressed or
not.

                  SECTION 109.  Separability Clause.

                  In case any provision in this  Indenture or in the Notes shall
be invalid, illegal or unenforceable,  the validity, legality and enforceability
of the  remaining  provisions  shall  not in any  way be  affected  or  impaired
thereby.

any legal or equitable right, remedy or claim under this Indenture.

the Trust  Indenture  Act that are  required  to be part of this  Indenture  and

                  In any case where any Interest  Payment Date,  Redemption Date

as if made on such Interest  Payment Date or  Redemption  Date, or at the Stated

collectively  referred to herein as the "Global Notes".  Ownership of beneficial
interests  in  Global  Notes  will  be  limited  to   Participants  or  Indirect

                  The definitive Notes shall be typed, printed,  lithographed or
engraved or produced by any  combination  of these methods or may be produced in
any other manner permitted by the rules of any securities  exchange on which the

evidenced by their execution of such Notes.

                  SECTION 202.  Restrictive Legends.

                  Unless and until a Note is exchanged  for an Exchange  Note in
connection with an effective Registration Statement pursuant to the Registration
Rights  Agreement,  Rule 144A Global Notes,  Regulation S Temporary Global Notes
and each Rule 144A  Certificated  Note  shall  bear the  following  legend  (the
"Private Placement Legend") on the face thereof:

         THE  NOTES  EVIDENCED   HEREBY  HAVE  NOT  BEEN  REGISTERED  UNDER  THE
         SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY STATE
         OR  OTHER  SECURITIES  LAWS.  NEITHER  THIS  NOTE NOR ANY  INTEREST  OR
         PARTICIPATION  HEREIN MAY BE REOFFERED,  SOLD,  ASSIGNED,  TRANSFERRED,
         PLEDGED,  ENCUMBERED  OR  OTHERWISE  DISPOSED OF IN THE ABSENCE OF SUCH
         REGISTRATION  OR UNLESS THE  TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT
         TO, THE REGISTRATION  REQUIREMENTS OF THE SECURITIES ACT. THE HOLDER OF
         THIS SECURITY BY ITS ACCEPTANCE  HEREOF (1) REPRESENTS THAT (A) IT IS A
         "QUALIFIED  INSTITUTIONAL  BUYER"  (AS  DEFINED  IN RULE 144A UNDER THE
         SECURITIES  ACT) OR (B) IT IS NOT A U.S.  PERSON AND IS  ACQUIRING  ITS
         NOTE IN AN "OFFSHORE  TRANSACTION" PURSUANT TO RULE 904 OF REGULATION S
         UNDER THE SECURITIES  ACT, (2) AGREES THAT IT WILL NOT PRIOR TO (X) THE
         DATE WHICH IS TWO YEARS (OR SUCH SHORTER PERIOD OF TIME AS PERMITTED BY
         RULE  144(k)  UNDER  THE  SECURITIES  ACT  OR ANY  SUCCESSOR  PROVISION
         THEREUNDER) AFTER THE LATER OF
<PAGE>
                                       32

         THE ORIGINAL ISSUE DATE HEREOF (OR OF ANY  PREDECESSOR OF THIS NOTE) OR
         THE LAST DAY ON WHICH THE COMPANY OR ANY  AFFILIATE  OF THE COMPANY WAS
         THE OWNER OF THIS NOTE (OR ANY  PREDECESSOR  OF THIS NOTE) AND (Y) SUCH
         LATER DATE, IF ANY, AS MAY BE REQUIRED BY APPLICABLE  LAWS (THE "RESALE
         RESTRICTION  TERMINATION  DATE") OFFER, SELL OR OTHERWISE TRANSFER THIS
         NOTE  EXCEPT  (A)  TO  THE  COMPANY,  (B)  PURSUANT  TO A  REGISTRATION
         STATEMENT  WHICH HAS BEEN DECLARED  EFFECTIVE UNDER THE SECURITIES ACT,
         (C) FOR SO LONG AS THE NOTES ARE ELIGIBLE  FOR RESALE  PURSUANT TO RULE
         144A, TO A PERSON IT REASONABLY BELIEVES IS A "QUALIFIED  INSTITUTIONAL
         BUYER" AS DEFINED IN RULE 144A UNDER THE  SECURITIES ACT THAT PURCHASES
         FOR ITS OWN  ACCOUNT OR FOR THE  ACCOUNT OF A  QUALIFIED  INSTITUTIONAL
         BUYER TO WHOM  NOTICE  IS  GIVEN  THAT THE  TRANSFER  IS BEING  MADE IN
         RELIANCE  ON RULE 144A,  (D)  PURSUANT  TO OFFERS AND SALES TO NON-U.S.
         PERSONS  THAT OCCUR  OUTSIDE  THE UNITED  STATES  WITHIN THE MEANING OF
         REGULATION  S UNDER  THE  SECURITIES  ACT OR (E)  PURSUANT  TO  ANOTHER
         AVAILABLE   EXEMPTION  FROM  THE   REGISTRATION   REQUIREMENTS  OF  THE
         SECURITIES  ACT AND (3) AGREES THAT IT WILL GIVE TO EACH PERSON TO WHOM
         THIS NOTE IS TRANSFERRED A NOTICE  SUBSTANTIALLY  TO THE EFFECT OF THIS
         LEGEND;  PROVIDED THAT THE COMPANY, THE TRUSTEE AND THE REGISTRAR SHALL
         HAVE THE RIGHT PRIOR TO ANY SUCH OFFER,  SALE OR  TRANSFER,  IN EACH OF
         THE FOREGOING CASES, TO REQUIRE THAT A CERTIFICATION OF TRANSFER IN THE
         FORM  APPEARING  ON THE  OTHER  SIDE OF  THIS  NOTE  IS  COMPLETED  AND
         DELIVERED BY THE  TRANSFEROR  TO THE TRUSTEE.  IN  CONNECTION  WITH ANY
         TRANSFER  OF THIS NOTE WITHIN THE TIME  PERIOD  REFERRED TO ABOVE,  THE
         HOLDER MUST CHECK THE  APPROPRIATE  BOX SET FORTH ON THE REVERSE HEREOF
         RELATING TO THE MANNER OF SUCH TRANSFER AND SUBMIT THIS  CERTIFICATE TO
         THE TRUSTEE. THIS LEGEND WILL BE REMOVED UPON THE REQUEST OF THE HOLDER
         AFTER THE RESALE  RESTRICTION  TERMINATION  DATE.  AS USED HEREIN,  THE
         TERMS "OFFSHORE  TRANSACTION,"  "UNITED STATES" AND "U.S.  PERSON" HAVE
         THE MEANINGS GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT.

                  Until the  Separation  Date,  each Note  also  shall  bear the
following legend (the "Separability Legend"):

         UNTIL THE SEPARATION  DATE (AS DEFINED),  THIS NOTE HAS BEEN ISSUED AS,
         AND MUST BE TRANSFERRED AS, A UNIT TOGETHER WITH THE
<PAGE>
                                       33

         ASSOCIATED WARRANTS TO PURCHASE COMMON STOCK OF THE COMPANY.  EACH UNIT
         CONSISTS OF $1,000  PRINCIPAL AMOUNT OF NOTES AND A WARRANT TO PURCHASE
         1.25141  SHARES OF COMMON STOCK OF THE COMPANY,  SUBJECT TO  ADJUSTMENT
         UNDER CERTAIN  CIRCUMSTANCES.  A COPY OF THE WARRANT AGREEMENT PURSUANT
         TO WHICH THE WARRANTS  HAVE BEEN ISSUED IS  AVAILABLE  FROM THE COMPANY
         UPON REQUEST.

                  Each Global Note,  whether or not an Exchange Note, shall also
bear the following legend on the face thereof:

         UNLESS THIS CERTIFICATE IS PRESENTED,  BY AN AUTHORIZED  REPRESENTATIVE
         OF THE  DEPOSITORY  TRUST  COMPANY,  TO THE  COMPANY  OR ITS  AGENT FOR
         REGISTRATION  OF  TRANSFER,  EXCHANGE OR PAYMENT,  AND ANY  CERTIFICATE
         ISSUED IS  REGISTERED IN THE NAME OF CEDE & CO. OR TO SUCH OTHER ENTITY
         AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST
         COMPANY OR SUCH OTHER REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY OR
         SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED  REPRESENTATIVE OF THE
         DEPOSITORY  TRUST COMPANY (AND ANY PAYMENT HEREON IS MADE TO CEDE & CO.
         OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE
         OF THE DEPOSITORY  TRUST  COMPANY),  ANY TRANSFER,  PLEDGE OR OTHER USE
         HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL SINCE THE
         REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

         TRANSFERS  OF THIS GLOBAL NOTE SHALL BE LIMITED TO  TRANSFERS IN WHOLE,
         BUT NOT IN PART, TO NOMINEES OF CEDE & CO. OR TO A SUCCESSOR THEREOF OR
         SUCH SUCCESSOR'S  NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL NOTE
         SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE  RESTRICTIONS
         SET FORTH IN SECTIONS 311 AND 312 OF THE INDENTURE.

                  The  aggregate   principal   amount  of  Notes  which  may  be
authenticated  and delivered  under this  Indenture is limited to  $160,000,000,
except for Notes  authenticated  and delivered upon registration of transfer of,
or in exchange  for, or in lieu of, other Notes  pursuant to Section  303,  304,
305, 306, 906, 1010, 1017 or 1108.

                  The Initial  Notes shall be known and  designated  as the "12%
Senior Notes due 2008" of the Company and the Exchange  Notes shall be known and
designated  as the "12%  Series A Senior  Notes  due 2008" of the  Company.  The
Stated  Maturity  of the  principal  of the Notes shall be May 15, 2008 and they
shall bear interest at the rate of 12% per annum, payable on May 15 and November
15 of each year, commencing on November 15, 1998, until the principal thereof is
paid or duly  provided  for.  Interest  on the Notes will  accrue  from the most
recent Interest Payment Date for which interest has been paid or, if no interest
has been paid, from the Issue Date.

                  The principal of (and premium and Liquidated  Damages, if any)
and  interest  on the  Notes  shall be  payable  at the  office or agency of the
Company  maintained for such purpose pursuant to Section 1002, or, at the option
of the Company, interest may be paid by check mailed to addresses of the Persons
entitled  thereto as such addresses shall appear on the Register;  provided that
all payments with respect to the Global Notes and Certificated Notes the Holders
of which have given wire transfer  instructions  to the Company will be required
to be made by wire  transfer  of  immediately  available  funds to the  accounts
specified by the Holders thereof.

                  The Notes shall be redeemable as provided in Article Eleven.

                  SECTION 302.  Denominations.

                  The Notes shall be  issuable  only in fully  registered  form,
without coupons, and only in denominations of $1,000 in principal amount and any
integral multiple thereof.

                  SECTION 303.  Execution, Authentication, Delivery and Dating.

                  The Notes  shall be  executed  on behalf of the Company by its
chairman,  its president,  chief financial  officer or any Vice  President.  The
signature  of any of these  officers  on the Notes  may be  manual or  facsimile
signatures  of the  present or any future  such  authorized  officer  and may be
imprinted or otherwise reproduced on the Notes.

                  Notes   bearing  the  manual  or   facsimile   signatures   of
individuals  who were at any time the proper  officers of the Company shall bind
the Company, notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the  authentication and delivery of such Notes or did
not hold such offices at the date of such Notes.

                                       35

                  At any time and from  time to time  after  the  execution  and
delivery of this  Indenture,  the Company may deliver  Initial Notes executed by
the Company to the Trustee for authentication, together with a Company Order for
the  authentication  and delivery of such Initial Notes directing the Trustee to
authenticate  the Notes and  certifying  that all  conditions  precedent  to the
issuance  of Notes  contained  herein  have been fully  complied  with,  and the
Trustee in  accordance  with such Company Order shall either at one time or from
time  to  time  pursuant  to  such  instruction  as  may be  described  therein,
authenticate  and  deliver  such  Notes as in this  Indenture  provided  and not
otherwise. The Trustee shall, upon receipt of a Company Order,  authenticate for
original  issue Exchange  Notes in an aggregate  principal  amount not to exceed
$160,000,000;  provided that such Exchange Notes shall be issuable only upon the
valid surrender for cancellation of Initial Notes of a like aggregate  principal
amount in accordance with an Exchange Offer pursuant to the Registration  Rights
Agreement  and a  Company  Order  for  the  authentication  of  such  securities
certifying that all conditions precedent to the issuance have been complied with
(including the effectiveness of a registration  statement  related thereto).  In
each case, the Trustee shall be entitled to receive an Officer's Certificate and
an  Opinion  of  Counsel  of the  Company  that  it may  reasonably  request  in
connection  with such  authentication  of Notes.  Such order  shall  specify the
amount of Notes to be authenticated  and the date on which the original issue of
Initial Notes or Exchange Notes is to be authenticated.

                  Each Note shall be dated the date of its authentication.

                  No Note shall be entitled to any benefit under this  Indenture
or be valid or  obligatory  for any purpose  unless there appears on such Note a
certificate of authentication, substantially in the form provided for in Exhibit
A, duly executed by the Trustee by manual  signature of an  authorized  officer,
and such  certificate upon any Note shall be conclusive  evidence,  and the only
evidence, that such Note has been duly authenticated and delivered hereunder and
is entitled to the benefits of this Indenture.

                  In case the  Company,  pursuant  to  Article  Eight,  shall be
consolidated or merged with or into any other Person or shall convey,  transfer,
lease or otherwise  dispose of its  properties  and assets  substantially  as an
entirety in a transaction  or a series of  transactions  to any Person,  and the
successor Person resulting from such consolidation, or surviving such merger, or
into which the Company  shall have been  merged,  or the Person which shall have
received a conveyance,  transfer, lease or other disposition as aforesaid, shall
have  executed an  indenture  supplemental  hereto with the Trustee  pursuant to
Article  Eight,  any of the  Notes  authenticated  or  delivered  prior  to such
consolidation,  merger,  conveyance,  transfer,  lease or other disposition may,
from time to time,  at the request of the  successor  Person,  be exchanged  for
other Notes  executed in the name of the  successor  Person with such changes in
phraseology and form as may be  appropriate,  but otherwise in substance of like
tenor as the Notes  surrendered for such exchange and of like principal  amount;
and  the  Trustee,   upon  Company  Request  of  the  successor  Person,   shall
authenticate  and deliver  Notes as specified in such request for the purpose of
such
<PAGE>
                                       36

exchange.  If Notes shall at any time be authenticated  and delivered in any new
name of a successor  Person pursuant to this Section in exchange or substitution
for or upon registration of transfer of any Notes, such successor Person, at the
option of the  Holders  but  without  expense  to them,  shall  provide  for the
exchange  of all  Notes at the time  Outstanding  for  Notes  authenticated  and
delivered in such new name.

                  SECTION 304.  Temporary Notes.

                  Pending the preparation of definitive  Notes,  the Company may
execute,  and upon Company  Order the Trustee  shall  authenticate  and deliver,
temporary Notes which are printed,  lithographed,  typewritten,  mimeographed or
otherwise produced, in any authorized  denomination,  substantially of the tenor
of the  definitive  Notes  in lieu of  which  they  are  issued  and  with  such
appropriate  insertions,  omissions,  substitutions  and other variations as the
officers executing such Notes may determine,  as conclusively evidenced by their
execution of such Notes.

                  If  temporary  Notes  are  issued,  the  Company  shall  cause
definitive  Notes  to  be  prepared  without   unreasonable   delay.  After  the
preparation of definitive  Notes,  the temporary Notes shall be exchangeable for
definitive  Notes upon surrender of the temporary  Notes at the office or agency
of the Company  designated  for such  purpose  pursuant to Section  1002 without
charge  to the  Holder.  Upon  surrender  for  cancellation  of any  one or more
temporary  Notes,  the Company  shall execute and upon Company Order the Trustee
shall  authenticate and deliver in exchange  therefor a like principal amount of
definitive Notes of authorized denominations.  Until so exchanged, the temporary
Notes  shall in all  respects  be  entitled  to the  same  benefits  under  this
Indenture as definitive Notes.

                  SECTION  305.  Registration,   Registration  of  Transfer  and
Exchange.

                  The  Company  shall  cause to be kept at the  Corporate  Trust
Office of the Trustee a register (the register  maintained in such office and in
any other  office or agency  designated  pursuant to Section  1002 being  herein
sometimes  referred to as the  "Register") in which,  subject to such reasonable
regulations as it may prescribe,  the Company shall provide for the registration
of Notes and of transfers of Notes. The Register shall be in written form or any
other form  capable of being  converted  into  written  form within a reasonable
time. At all reasonable  times,  the Register shall be open to inspection by the
Trustee.  The Trustee is hereby initially  appointed as security  registrar (the
"Registrar")  for the purpose of  registering  Notes and  transfers  of Notes as
herein provided.

                  Upon surrender for registration of transfer of any Note at the
office or agency of the Company designated pursuant to Section 1002, the Company
shall execute,  and the Trustee shall  authenticate and deliver,  in the name of
the designated transferee or transferees, one or
<PAGE>
                                       37

more new  Notes  of  any  authorized  denomination or  denominations  of  a like
aggregate principal amount.

                  At the option of the Holder,  Notes may be exchanged for other
Notes of any authorized  denomination and of a like aggregate  principal amount,
upon  surrender of the Notes to be exchanged at such office or agency.  Whenever
any Notes are so surrendered  for exchange,  the Company shall execute,  and the
Trustee shall,  upon receipt of a Company Order,  authenticate and deliver,  the
Notes which the Holder making the exchange is entitled to receive; provided that
no exchange of Initial  Notes for  Exchange  Notes shall occur until an Exchange
Offer  Registration   Statement  shall  have  been  declared  effective  by  the
Commission,  the Trustee shall have received an Officer's Certificate confirming
that the Exchange Offer  Registration  Statement has been declared  effective by
the  Commission  and the Initial  Notes to be exchanged  for the Exchange  Notes
shall be cancelled by the Trustee.

                  All Notes issued upon any registration of transfer or exchange
of Notes shall be the valid  obligations  of the  Company,  evidencing  the same
debt,  and  entitled to the same  benefits  under this  Indenture,  as the Notes
surrendered upon such registration of transfer or exchange.

                  Every  Note  presented  or  surrendered  for  registration  of
transfer or for exchange  shall be duly endorsed and be accompanied by a written
instrument of transfer,  in form  satisfactory to the Company and the Registrar,
duly executed by the Holder thereof or his attorney duly authorized in writing.

                  No  service  charge  shall  be made  for any  registration  of
transfer or exchange or redemption of Notes,  but the Company or the Trustee may
require  payment  of a sum  sufficient  to cover  any tax or other  governmental
charge that may be imposed in connection  with any  registration  of transfer or
exchange of Notes, other than exchanges pursuant to Section 304, 906, 1010, 1017
or 1108 not involving any transfer.

                  The Company  shall not be required (i) to issue,  register the
transfer of or exchange  any Note  during a period  beginning  at the opening of
business 15 days before the selection of Notes to be redeemed under Section 1104
and ending at the close of business on the day of such  mailing of the  relevant
notice of  redemption,  or (ii) to register the transfer of or exchange any Note
so selected for redemption in whole or in part, except the unredeemed portion of
any Note being redeemed in part.

                  SECTION 306.  Mutilated, Destroyed, Lost and Stolen Notes.

                  If (i) any mutilated Note is  surrendered  to the Trustee,  or
(ii) the Company and the Trustee receive  evidence to their  satisfaction of the
destruction,  loss or theft of any Note,  and there is  delivered to the Company
and the Trustee  such  security or  indemnity as may be required by them to save
each of them  harmless,  then,  in the  absence of notice to the  Company or the
Trustee that such Note has been acquired by a bona fide  purchaser,  the Company
shall execute and upon Company Order the Trustee shall authenticate and deliver,
in exchange for any such mutilated Note or in lieu of any such  destroyed,  lost
or stolen Note, a new Note of like tenor and principal amount,  bearing a number
not contemporaneously outstanding.

                  In case any such mutilated, destroyed, lost or stolen Note has
become or is about to become due and payable, the Company in its discretion may,
instead of issuing a new Note, pay such Note.

                  Upon the  issuance of any new Note under this Section 306, the
Company may require  the payment of a sum  sufficient  to cover any tax or other
governmental  charge  that may be  imposed  in  relation  thereto  and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

                  Every new Note issued  pursuant to this Section 306 in lieu of
any  mutilated,  destroyed,  lost or stolen  Note shall  constitute  an original
additional contractual obligation of the Company,  whether or not the mutilated,
destroyed,  lost or stolen Note shall be at any time enforceable by anyone,  and
shall be entitled to all benefits of this Indenture equally and  proportionately
with any and all other Notes duly issued hereunder.

                  The  provisions  of this Section 306 are  exclusive  and shall
preclude (to the extent  lawful) all other  rights and remedies  with respect to
the replacement or payment of mutilated, destroyed, lost or stolen Notes.

                  SECTION 307.  Payment of Interest; Interest Rights Preserved.

                  Interest on any Note which is payable,  and is punctually paid
or duly provided  for, on any Interest  Payment Date shall be paid to the Person
in whose name such Note (or  Predecessor  Notes) is  registered  at the close of
business on the Regular Record Date (or if a Predecessor  Note is outstanding on
such Regular Record Date, such Predecessor Note) for such interest at the office
or agency of the Company  maintained  for such purpose  pursuant to Section 1002
or, at the option of the  Company,  interest  may be paid by check mailed to the
address  of the Person  entitled  thereto as such  address  shall  appear on the
Register;   provided  that  all  payments  with  respect  to  Global  Notes  and
Certificated Notes the Holders of which have given

<PAGE>
                                       39

wire  transfer  instructions  to the Company will be required to be made by wire
transfer of immediately available funds to the accounts specified by the Holders
thereof.

                  Any  interest  on  any  Note  which  is  payable,  but  is not
punctually  paid or duly  provided  for,  on any  Interest  Payment  Date  shall
forthwith cease to be payable to the Holder on the Regular Record Date by virtue
of having  been such  Holder,  and such  defaulted  interest  and (to the extent
lawful) interest on such defaulted interest at the rate borne by the Notes (such
defaulted  interest and interest thereon herein  collectively  called "Defaulted
Interest") may be paid by the Company, at its election in each case, as provided
in clause (1) or (2) below:

                           (1) The  Company  may  elect to make  payment  of any
                  Defaulted Interest to the Persons in whose names the Notes (or
                  their  respective  Predecessor  Notes) are  registered  at the
                  close of business on a special  record date  ("Special  Record
                  Date") for the payment of such Defaulted Interest, which shall
                  be fixed in the following manner. The Company shall notify the
                  Trustee  in  writing  of  the  amount  of  Defaulted  Interest
                  proposed to be paid on each Note and the date of the  proposed
                  payment,  and at the same time the Company  shall deposit with
                  the Trustee an amount of money equal to the  aggregate  amount
                  proposed to be paid in respect of such  Defaulted  Interest or
                  shall make  arrangements  satisfactory to the Trustee for such
                  deposit prior to the date of the proposed payment,  such money
                  when  deposited  to be held in trust  for the  benefit  of the
                  Persons entitled to such Defaulted  Interest as in this clause
                  provided.  Thereupon  the Trustee  shall fix a Special  Record
                  Date for the payment of such Defaulted Interest which shall be
                  not more than 15 days and not less  than 10 days  prior to the
                  date of the  proposed  payment and not less than 10 days after
                  the  receipt  by the  Trustee  of the  notice of the  proposed
                  payment. The Trustee shall promptly notify the Company of such
                  Special Record Date and, in the name and at the expense of the
                  Company,  shall cause notice of the  proposed  payment of such
                  Defaulted  Interest and the Special Record Date therefor to be
                  given in the manner  provided for in Section 106 not less than
                  10 days  prior to such  Special  Record  Date.  Notice  of the
                  proposed  payment of such  Defaulted  Interest and the Special
                  Record  Date  therefor  having been so given,  such  Defaulted
                  Interest shall be paid to the Persons in whose names the Notes
                  (or their respective  Predecessor Notes) are registered at the
                  close of  business  on such  Special  Record Date and shall no
                  longer be payable pursuant to the following clause (2).

                           (2) The  Company  may make  payment of any  Defaulted
                  Interest in any other lawful manner not inconsistent  with the
                  requirements of any securities exchange on which the Notes may
                  be listed,  and upon such  notice as may be  required  by such
                  exchange, if, after notice given in writing by the Company to
<PAGE>
                                       40

                  the Trustee of the proposed  payment  pursuant to this clause,
                  such  manner of  payment  shall be deemed  practicable  by the
                  Trustee.

                  Subject to the foregoing  provisions of this Section 307, each
Note  delivered  under this  Indenture  upon  registration  of transfer of or in
exchange  for or in lieu of any other  Note shall  carry the rights to  interest
accrued and unpaid, and to accrue, which were carried by such other Note.

                  SECTION 308.  Persons Deemed Owners.

                  Prior to the due  presentment  of a Note for  registration  of
transfer,  the Company,  the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name such Note is  registered as the owner of such
Note for the purpose of receiving payment of principal of (and premium,  if any)
and  (subject to Sections  305 and 307)  interest on such Note and for all other
purposes  whatsoever,  whether  or not  such  Note be  overdue,  and none of the
Company,  the  Trustee  or any  agent of the  Company  or the  Trustee  shall be
affected by notice to the contrary.

                  SECTION 309.  Cancellation.

                  All Notes surrendered for payment, redemption, registration of
transfer or exchange shall, if surrendered to any Person other than the Trustee,
be delivered to, and promptly cancelled by, the Trustee.  The Company may at any
time deliver to the Trustee for cancellation any Notes previously  authenticated
and  delivered  hereunder  which the  Company  may have  acquired  in any manner
whatsoever,  and may deliver to the Trustee (or to any other Person for delivery
to the Trustee) for cancellation any Notes  previously  authenticated  hereunder
which the Company has not issued and sold,  and all Notes so delivered  shall be
promptly  cancelled by the Trustee.  If the Company  shall so acquire any of the
Notes,   however,  such  acquisition  shall  not  operate  as  a  redemption  or
satisfaction of the Indebtedness  represented by such Notes unless and until the
same  are  surrendered  to the  Trustee  for  cancellation.  No  Notes  shall be
authenticated  in lieu of or in exchange for any Notes  cancelled as provided in
this Section,  except as expressly  permitted by this  Indenture.  All cancelled
Notes held by the Trustee shall be disposed of by the Trustee in accordance with
its customary  procedures and  certification of their disposal  delivered to the
Company unless by Company Order the Company shall direct that cancelled Notes be
returned to it after being appropriately designated as cancelled.

                  SECTION 310.  Computation of Interest.

                  Interest  on the  Notes  shall be  computed  on the basis of a
360-day year of twelve 30-day months.

                  SECTION 311.  Book-Entry Provisions for Global Notes.

                  (a) Each Global Note initially  shall (i) be registered in the
name of the Depositary for such Global Notes or the nominee of such  Depositary,
(ii) be delivered to the Trustee as custodian for such Depositary and (iii) bear
legends as set forth in Section 202.

                  Except as provided  in Section  311(b),  owners of  beneficial
interests  in the Global  Notes will not have Notes  registered  in their names,
will not receive physical delivery of Notes in certificated form and will not be
considered the  registered  owner or Holder thereof under this Indenture for any
purpose.

                  Members of, or Participants  in, the Depositary  shall have no
rights under this  Indenture with respect to any Global Note, and the Depositary
may be treated by the  Company,  the Trustee and any agent of the Company or the
Trustee as the absolute  owner of such Global Note for all purposes  whatsoever.
Notwithstanding  the foregoing,  nothing  herein shall prevent the Company,  the
Trustee or any agent of the  Company or the Trustee  from  giving  effect to any
written certification,  proxy or other authorization furnished by the Depositary
or impair,  as between the  Depositary  and its  Participants,  the operation of
customary  practices  governing the exercise of the rights of a beneficial owner
of any Note.  The  registered  Holder of a Global  Note may  grant  proxies  and
otherwise authorize any person, including Participants and persons that may hold
interests through Participants, to take any action which a Holder is entitled to
take under this Indenture or the Notes.

                  (b)  Interests  of  beneficial  owners in a Global Note may be
transferred  in  accordance  with the  applicable  rules and  procedures  of the
Depositary and the  provisions of Section 312.  Transfers of a Global Note shall
be limited to  transfers of such Global Note in whole,  but not in part,  to the
Depositary,  a nominee of the  Depositary,  its  successors or their  respective
nominees.  Interests of beneficial owners in the Global Notes may be transferred
in accordance with the rules and procedures of the Depositary and the provisions
of  Section  312  hereof.   Rule  144A  Certificated   Notes  and  Regulation  S
Certificated  Notes shall be  transferred  to beneficial  owners in exchange for
their  beneficial  interests in the Rule 144A Global Note(s) or the Regulation S
Global  Note(s),  as the case may be, if (i) the  Depositary  (A)  notifies  the
Company that it is unwilling or unable to continue as depository  for the Global
Notes and the Company  thereupon fails to appoint a successor  depository or (B)
has ceased to be a clearing agency registered under the Exchange Act; (ii) there
shall have  occurred and be  continuing  an Event of Default with respect to the
Notes; or (iii) the Company, at its option, notifies the Trustee in writing that
it elects to cause issuance of the Notes in certificated form;  provided that in
no event shall the  Regulation  S  Temporary  Global  Note be  exchanged  by the
Company for Certificated Notes prior to (x) the end of the Restricted Period and
(y) receipt by the Trustee and the Company of a certificate substantially in the
form of Exhibit B hereto. In connection with a transfer of an entire Global Note
to beneficial owners pursuant to clause (i), (ii) or (iii) of this

<PAGE>
                                       42

paragraph (b), the  applicable  Global Note shall be deemed to be surrendered to
the Trustee for  cancellation,  and the Company shall  execute,  and the Trustee
shall  authenticate  and deliver,  to each  beneficial  owner  identified by the
Depositary  in exchange for its  beneficial  interest in the  applicable  Global
Note, an equal aggregate  principal amount of Rule 144A  Certificated  Notes (in
the case of the Rule 144A Global Note) or  Regulation S  Certificated  Notes (in
the case of the  Regulation S Global  Note),  as the case may be, of  authorized
denominations.

                  (c) Any beneficial interest in one of the Global Notes that is
transferred  to a Person who takes  delivery  in the form of an  interest in the
other Global Note will,  upon  transfer,  cease to be an interest in such Global
Note and become an interest  in the other  Global  Note and,  accordingly,  will
thereafter be subject to all transfer restrictions, if any, and other procedures
applicable to  beneficial  interests in such other Global Note for as long as it
remains such an interest.

                  (d) Any Rule 144A  Certificated Note delivered in exchange for
an  interest in the Rule 144A Global  Note  pursuant  to  paragraph  (b) of this
Section  shall,  unless such  exchange is made on or after the date which is two
years  following  the date hereof,  or such shorter  period of time as permitted
under Rule 144(k) under the Securities Act, and except as otherwise  provided in
Section 312, bear the Private Placement Legend.

                  SECTION 312.  Transfer Provisions.

                  Unless and until a Note is exchanged  for an Exchange  Note in
connection with an effective Registration Statement pursuant to the Registration
Rights Agreement, the following provisions shall apply:

                  (a) Transfers to QIBs.  The following  provisions  shall apply
         with respect to the  registration  of any  proposed  transfer of a Rule
         144A Certificated Note or an interest in the Rule 144A Global Note to a
         QIB (excluding Non-U.S. Persons):

                             (i) If the Note to be  transferred  consists of (x)
                  Rule 144A Certificated Notes, the Registrar shall register the
                  transfer  if  such  transfer  is  being  made  by  a  proposed
                  transferor who has checked the box provided for on the form of
                  Note  stating,  or has  otherwise  advised the Company and the
                  Registrar  in  writing,   that  the  sale  has  been  made  in
                  compliance  with the  provisions  of Rule 144A to a transferee
                  who has signed the  certification  provided for on the form of
                  Note  stating,  or has  otherwise  advised the Company and the
                  Registrar in writing,  that it is purchasing  the Note for its
                  own account (or an account  with respect to which it exercises
                  sole  investment  discretion) and that each of it and any such
                  account  is a QIB,  and is aware  that the sale to it is being
                  made in  reliance  on Rule 144A and  acknowledges  that it has
                  received such information regarding the Company as it

                  has requested  pursuant to Rule 144A or has  determined not to
                  request  such  information  and  that  it is  aware  that  the
                  transferor  is relying upon its foregoing  representations  in
                  order to claim the  exemption  from  registration  provided by
                  Rule 144A or (y) an interest in the Rule 144A Global Note, the
                  transfer of such  interest  may be effected  only  through the
                  book-entry system maintained by the Depositary.

                            (ii) If the proposed  transferee  is a  Participant,
                  and  the  Note  to  be  transferred   consists  of  Rule  144A
                  Certificated  Notes,  upon  receipt  by the  Registrar  of the
                  documents  referred to in clause (i)(x) and instructions given
                  in  accordance  with  the  Depositary's  and  the  Registrar's
                  procedures,  the  Registrar  shall  reflect  on its  books and
                  records the date and an increase  in the  principal  amount of
                  the Rule 144A Global Note in an amount equal to the  principal
                  amount of the Rule 144A Certificated  Notes to be transferred,
                  and the Trustee shall cancel the Rule 144A  Certificated  Note
                  so transferred.

                  (b)  Transfers  of  Interests  in the  Regulation  S Temporary
         Global Note to QIBs. The following  provisions shall apply with respect
         to registration of any proposed transfer of interests in the Regulation

                  and the proposed  transferor  has delivered to the Registrar a
                  certificate  substantially  in the form of Exhibit C hereto or
                  (y) if the  proposed  transferee  is a QIB  and  the  proposed

                  Note  stating,  or has  otherwise  advised the Company and the
                  Registrar  in  writing,   that  the  sale  has  been  made  in

                  account is a QIB within the meaning of Rule 144A, and is aware
                  that the sale to it is being made in reliance on Rule 144A and

                             (i) The  Registrar  shall  register the transfer of
                  any such Note without requiring any additional certification.

                            (ii) (A) If the proposed transferor is a Participant
                  holding a  beneficial  interest in the  Regulation S Permanent
                  Global Note,  upon receipt by the Registrar of instructions in
                  accordance   with  the   Depositary's   and  the   Registrar's
                  procedures,  the  Registrar  shall  reflect  on its  books and

                  Depositary's  and the  Registrar's  procedures,  the Registrar
                  shall  reflect  on its  books  and  records  the  date  and an
                  increase in the principal  amount of the Rule 144A Global Note
                  in an amount equal to the principal amount of the Regulation S
                  Certificated  Notes or the Regulation S Permanent Global Note,
                  as the case may be, to be  transferred,  and the Trustee shall
                  cancel  the  Certificated  Note,  if any,  so  transferred  or

                  of a certificate substantially in the form of Exhibit C hereto
                  from the proposed transferor.

                            (ii) On and after  the  later of (x) the  Separation
                  Date and (y) June 29, 1998,  the Registrar  shall register any

                  the
<PAGE>

                  Rule  144A  Global  Note,   upon  receipt  of  a   certificate
                  substantially  in the  form  of  Exhibit  C  hereto  from  the
                  proposed transferor.

                           (iii) (A) If the proposed transferor is a Participant
                  holding a  beneficial  interest in the Rule 144A Global  Note,
                  upon  receipt  by the  Registrar  of the  documents,  if  any,
                  required by paragraph (ii) and instructions in accordance with
                  the Depositary's and the Registrar's procedures, the Registrar
                  shall reflect on its books and records the date and a decrease
                  in the  principal  amount of the Rule 144A  Global  Note in an
                  amount  equal  to  the  principal  amount  of  the  beneficial
                  interest in the Rule 144A Global Note to be  transferred,  and
                  (B) if the proposed transferee is a Participant,  upon receipt
                  by the Registrar of instructions  given in accordance with the
                  Depositary's  and the  Registrar's  procedures,  the Registrar
                  shall  reflect  on its  books  and  records  the  date  and an
                  increase in the  principal  amount of the  Regulation S Global

                  144A  Certificated  Notes or the Rule 144A Global Note, as the
                  case may be, to be  transferred,  and the Trustee shall cancel
                  the Certificated  Note, if any, so transferred or decrease the
                  amount of the Rule 144A Global Note.

                  (e) Private Placement Legend.  Upon the transfer,  exchange or
         replacement  of Notes not  bearing the Private  Placement  Legend,  the
         Registrar  shall deliver  Notes that do not bear the Private  Placement
         Legend. Upon the transfer, exchange or replacement of Notes bearing the
         Private Placement  Legend,  the Registrar shall deliver only Notes that
         bear  the  Private   Placement   Legend   unless   either   (i)(A)  the
         circumstances  contemplated  by the fourth  paragraph of Section 201 or
         Section  312(d)(ii)  exist or (B) the  requested  transfer is after the
         time period referred to in Rule 144(k) under the Securities Act or (ii)
         there is  delivered to the  Registrar an Opinion of Counsel  reasonably
         satisfactory  to the Company and the Trustee to the effect that neither
         such legend nor the related  restrictions  on transfer  are required in
         order to maintain compliance with the provisions of the Securities Act.

                  (f) General. By its acceptance of any Note bearing the Private
         Placement  Legend,   each  Holder  of  such  a  Note  acknowledges  the
         restrictions  on transfer of such Note set forth in this  Indenture and
         in the Private  Placement Legend and agrees that it shall transfer such
         Note  only as  provided  in this  Indenture.  The  Registrar  shall not
         register a transfer of any Note unless such transfer  complies with the
         restrictions on transfer of such Note set forth in this  Indenture.  In
         connection  with any  transfer  of  Notes,  each  Holder  agrees by its
         acceptance  of the Notes to furnish the  Registrar  or the Company such
         certifications,  legal opinions or other  information as either of them
         may  reasonably  require to confirm  that such  transfer  is being made
         pursuant to an exemption  from,  or a  transaction  not subject to, the
         registration requirements of the Securities Act;

<PAGE>
                                       46

         provided that the Registrar shall not be required to determine (but may
         rely  on a  determination  made by the  Company  with  respect  to) the
         sufficiency  of  any  such  certifications,  legal  opinions  or  other
         information.

                  The Registrar shall retain copies of all letters,  notices and
other written  communications  received  pursuant to Section 311 or this Section
312.  The  Company  shall have the right to inspect  and make copies of all such
letters, notices or other written communications at any reasonable time upon the
giving of reasonable written notice to the Registrar.

                  SECTION 313.  Separation of Notes and Warrants.

                  (a)  Prior  to the  Separation  Date,  no  Notes  may be sold,
         assigned or otherwise transferred to any Person unless,  simultaneously
         with such transfer,  the Trustee receives confirmation from the Warrant
         Agent for the  Warrants  that the Holder of the Notes has  requested  a
         transfer of the related Warrants to the same transferee.

                  (b) On or after the  Separability  Date,  the Holder of a Note
         containing a Separability Legend may surrender such Note accompanied by
         a written application to the Trustee,  duly executed by the Holder, for
         a new Note or Notes not  containing a Separability  Legend.  Whether or
         not the  Holder  obtains  a new Note,  from and after the  Separability
         Date, the Separability Legend shall have no further force and effect.

further  effect as to all  Outstanding  Notes (except as to surviving  rights of
registration  of transfer or exchange of the Notes,  as  expressly  provided for
herein or pursuant hereto) and the Trustee, at the expense of the Company, shall
execute  proper  instruments  acknowledging  satisfaction  and discharge of this
Indenture when:

         discharge of this Indenture have been complied with.

                  Notwithstanding   the   satisfaction  and  discharge  of  this
Indenture,  the obligations of the Company to the Trustee under Section 606 and,
if money shall have been deposited with the Trustee pursuant to subclause (b) of

entitled thereto,  of the principal (and premium, if any) and interest for whose
payment such money has been deposited with the Trustee.

                  SECTION  502.   Acceleration   of  Maturity:   Rescission  and
Annulment.

                  If an  Event  of  Default  (other  than an  Event  of  Default
specified in Section 501(9) or 501(10))  occurs and is  continuing,  then and in
every  such case the  Trustee or the  Holders of not less than 25% in  aggregate
principal amount of the Notes Outstanding, by a notice in writing to the Company
(and to the Trustee if such notice given by such Holders),  may, and the Trustee
at the request of such Holders shall, declare the principal of, premium, if any,
and accrued but unpaid interest and Liquidated Damages, if any, on all the Notes
to be immediately due and payable.  Upon any such  declaration of  acceleration,
such principal of, premium,  if any, accrued interest and Liquidated Damages, if
any, shall become immediately due and payable.  If an Event of Default specified
in Section 501(9) or 501(10)  occurs,  then the principal of,  premium,  if any,
accrued interest and Liquidated  Damages, if any, shall ipso facto become and be
immediately  due and payable without any declaration or other act on the part of
the Trustee or any Holder.

                  At any time after a declaration of acceleration has been made,
the Holders of at least a majority in  aggregate  principal  amount of the Notes
Outstanding,  by written  notice to the Company and the  Trustee,  may waive all
past defaults and rescind and annul such declaration and its consequences if:

                  (1) all existing Events of Default,  other than the nonpayment
         of  amounts  of  principal  of,  premium,  if any,  accrued  and unpaid
         interest and Liquidated Damages, if any, on the Notes which have become
         due  solely by such  declaration  of  acceleration,  have been cured or
         waived (subject to the limitations set forth in Section 513); and

<PAGE>
                                       51

                  (2) the  rescission,  in the  Opinion  of  Counsel,  would not
         conflict  with  any  judgment  or  decrees  of  a  court  of  competent
         jurisdiction.

No such  rescission  shall  affect  any  subsequent  default or impair any right
consequent thereon.

                  Notwithstanding  the  preceding  paragraph,  in  the  event  a
declaration of  acceleration in respect of the Notes because an Event of Default
specified  in  Section  501(7)  shall  have  occurred  and be  continuing,  such
declaration  of  acceleration  shall be  automatically  annulled  if the default
triggering  such  Event of Default  has been  remedied  or cured by the  Company
and/or the  relevant  Significant  Subsidiaries  or waived by the Holders of the
relevant  Indebtedness within 60 days after the declaration of acceleration with
respect thereto.

                  SECTION  503.   Collection  of  Indebtedness   and  Suits  for
Enforcement by Trustee.

                  The Company covenants that if

                  (a)  default  is made in the  payment  of any  installment  of
         interest and Liquidated Damages, if any, on any Note when such interest
         becomes due and payable and such default  continues  for a period of 30
         days, or

                  (b)  default is made in the  payment of the  principal  of (or
         premium, if any, on) any Note at the Maturity thereof,

the  Company  shall pay to the  Trustee  for the  benefit of the Holders of such
Notes,  the whole amount then due and payable on such Notes for  principal  (and
premium, if any) and interest,  and (Liquidated Damages, if any) and interest on
any overdue  principal (and premium,  if any) and, to the extent that payment of
such interest  shall be legally  enforceable,  upon any overdue  installment  of
interest and Liquidated Damages, if any, at the rate borne by the Notes, and, in
addition thereto,  such further amount as shall be sufficient to cover the costs
and  expenses  of  collection,  including  the  reasonable  compensation,  fees,
expenses,  disbursements and advances of the Trustee, its agents and counsel and
any other amounts due the Trustee or any predecessor Trustee.

                  If the Company fails to pay such amounts  forthwith  upon such
demand,  the  Trustee,  in its own name as  trustee  of an  express  trust,  may
institute  a  judicial  proceeding  for the  collection  of the  sums so due and
unpaid,  may  prosecute  such  proceeding  to judgment  or final  decree and may
enforce the same  against the  Company or any other  obligor  upon the Notes and
collect the moneys  adjudged or decreed to be payable in the manner  provided by
law out of the  property  of the  Company or any other  obligor  upon the Notes,
wherever situated.

<PAGE>
                                       52

                  If an Event of Default occurs and is  continuing,  the Trustee
may in its  discretion  proceed to protect and enforce its rights and the rights
of the Holders by such  appropriate  judicial  proceedings  as the Trustee shall
deem most  effectual  to protect and enforce  any such  rights,  whether for the
specific enforcement of any covenant or agreement in this Indenture or in aid of
the exercise of any power granted herein, or to enforce any other proper remedy.

                  SECTION 504.  Trustee May File Proofs of Claim.

                  In  case  of the  pendency  of any  receivership,  insolvency,
liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or
other judicial  proceeding relative to the Company or any other obligor upon the
Notes  or the  property  of the  Company  or of  such  other  obligor  or  their
creditors, the Trustee (irrespective of whether the principal of the Notes shall
then be due and payable as therein  expressed or by declaration or otherwise and
irrespective  of whether the  Trustee  shall have made any demand on the Company
for the payment of overdue  principal,  premium,  if any, interest or Liquidated
Damages,  if any) shall be  entitled  and  empowered,  by  intervention  in such
proceeding or otherwise,

                  (i) to file  and  prove  a  claim  for  the  whole  amount  of
         principal  (and premium and  Liquidated  Damages,  if any) and interest
         owing and unpaid in respect of the Notes and to file such other  papers
         or documents and take other  actions as the Trustee may deem  necessary
         or advisable in order to have the claims of the Trustee  (including any
         claim for the  reasonable  compensation,  expenses,  disbursements  and
         advances of the  Trustee,  its agents and  counsel)  and of the Holders
         allowed in such judicial proceeding, and

                  (ii) to  collect  and  receive  any  moneys or other  property
         payable or deliverable on any such claims and to distribute the same;

and any custodian,  receiver,  assignee,  trustee,  liquidator,  sequestrator or
similar  official in any such judicial  proceeding is hereby  authorized by each
Holder to make such  payments to the Trustee  and, in the event that the Trustee
shall consent to the making of such payments directly to the Holders, to pay the
Trustee  any  amount  due  it  for  the   reasonable   compensation,   expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee or any Predecessor Trustee under Section 606.

                  Nothing  herein  contained  shall be deemed to  authorize  the
Trustee  to  authorize  or consent to or accept or adopt on behalf of any Holder
any plan of reorganization, arrangement, adjustment or composition affecting the
Notes or the rights of any Holder  thereof,  or to authorize the Trustee to vote
in respect of the claim of any Holder in any such proceeding.

Notes.

                  All rights of action and claims  under this  Indenture  or the
Notes may be prosecuted  and enforced by the Trustee  without the  possession of
any of the Notes or the production  thereof in any proceeding  relating thereto,
and any such  proceeding  instituted  by the Trustee shall be brought in its own
name and as trustee of an express  trust,  and any  recovery of judgment  shall,
after provision for the payment of the reasonable compensation,  fees, expenses,
disbursements  and advances of the Trustee,  its agents and counsel,  be for the
ratable  benefit of the  Holders of the Notes in respect of which such  judgment
has been recovered.

                  SECTION 506.  Application of Money Collected.

                  Any money  collected  by the Trustee  pursuant to this Article
shall be  applied  in the  following  order,  at the date or dates  fixed by the
Trustee and, in case of the  distribution  of such money on account of principal
(or  premium,  if  any,  or  Liquidated  Damages,  if  any)  or  interest,  upon
presentation  of the Notes  and the  notation  thereon  of the  payment  if only
partially paid and upon surrender thereof if fully paid:

         Section 606;

                  SECOND:  To the payment of the amounts then due and unpaid for
         principal  of  (and  premium,  if any)  and  interest  (and  Liquidated
         Damages, if any) on the Notes in respect of which or for the benefit of
         which such money has been  collected,  ratably,  without  preference or
         priority of any kind,  according to the amounts due and payable on such
         Notes for principal  (and premium and Liquidated  Damages,  if any) and
         interest, respectively; and

                  THIRD: The balance,  if any, to the Person or Persons entitled
         thereto.

                  SECTION 507.  Limitation on Suits.

                  Except to enforce the right to receive payment of principal or
premium,  if any, or interest or Liquidated Damages, if any, when due, no Holder
of any Notes  shall have any right to  institute  any  proceeding,  judicial  or
otherwise,  with respect to this Indenture, or for the appointment of a receiver
or trustee, or for any other remedy hereunder,  unless the following  conditions
have been met:

                  (1) such Holder has  previously  given  written  notice to the
         Trustee of a continuing Event of Default;

<PAGE>
                                       54

                  (2) the  Holders of not less than 25% in  aggregate  principal
         amount of the Outstanding  Notes shall have made written request to the
         Trustee to pursue the remedy in respect of such Event of Default in its
         own name as Trustee hereunder;

                  (3)  such  Holder  or  Holders  have  offered  to the  Trustee
         indemnity  satisfactory to the Trustee against any costs,  expenses and
         liabilities to be incurred in compliance with such request;

                  (4) the Trustee has failed to  institute  any such  proceeding
         for 60 days after its  receipt  of such  notice,  request  and offer of
         indemnity; and

                  (5) during such 60-day period, no direction  inconsistent with
         such written  request has been given to the Trustee by the Holders of a
         majority  or more in  aggregate  principal  amount  of the  Outstanding
         Notes;

it being  understood  and intended  that no one or more  Holders  shall have any
right in any manner  whatever by virtue of, or by availing of, any  provision of
this Indenture to affect,  disturb or prejudice the rights of any other Holders,
or to obtain or to seek to obtain  priority or preference over any other Holders
or to enforce  any right  under  this  Indenture,  except in the  manner  herein
provided and for the equal and ratable benefit of all the Holders.

                  SECTION  508.   Unconditional  Right  of  Holders  to  Receive
Principal, Premium and Interest.

                  Notwithstanding  any other  provision in this  Indenture,  the
Holder of any Note shall have the right, which is absolute and unconditional, to
receive payment, as provided herein (including, if applicable, Article Thirteen)
and in such Note of the  principal  of (and  premium,  if any) and  (subject  to
Section 307) accrued  interest (and  Liquidated  Damages,  if any) on the Stated
Maturities  expressed  in such  Note  (or,  in the  case of  redemption,  on the
Redemption  Date) and to institute suit for the  enforcement of any such payment
on or after such Stated Maturity,  and such rights shall not be impaired without
the consent of such Holder.

                  SECTION 509.  Restoration of Rights and Remedies.

                  If the Trustee or any Holder has  instituted any proceeding to
enforce any right or remedy under this  Indenture and such  proceeding  has been
discontinued or abandoned for any reason,  or has been  determined  adversely to
the  Trustee or to such  Holder,  then and in every  such  case,  subject to any
determination in such proceeding, the Company, the Trustee and the Holders shall
be restored  severally and respectively to their former positions  hereunder and
thereafter all rights and remedies of the Trustee and the Holders shall continue
as though no such proceeding had been instituted.

                  SECTION 510.  Rights and Remedies Cumulative.

                  Except as otherwise  provided with respect to the  replacement
or payment of mutilated,  destroyed,  lost or stolen Notes in the last paragraph
of Section  306,  no right or remedy  herein  conferred  upon or reserved to the
Trustee or to the  Holders is  intended  to be  exclusive  of any other right or
remedy,  and every right and remedy  shall,  to the extent  permitted by law, be
cumulative  and in addition to every other right and remedy  given  hereunder or
now or hereafter  existing at law or in equity or  otherwise.  The  assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

                  SECTION 511.  Delay or Omission Not Waiver.

                  No delay or  omission  of the  Trustee or of any Holder of any
Note to exercise any right or remedy  accruing  upon any Event of Default  shall
impair  any such  right or remedy or  constitute  a waiver of any such  Event of
Default or an acquiescence therein. Every right and remedy given by this Article
or by law to the Trustee or to the Holders may be  exercised  from time to time,
and as often as may be deemed  expedient,  by the Trustee or by the Holders,  as
the case may be.

                  SECTION 512.  Control by Holders.

                  The Holders of not less than a majority in aggregate principal
amount of the Outstanding  Notes shall have the right to direct the time, method
and place of conducting any proceeding for any remedy  available to the Trustee,
or exercising any trust or power conferred on the Trustee, provided that

                  (1) the Trustee need not take any action that  conflicts  with
         law or this  Indenture,  which  might  involve  the Trustee in personal
         liability or which, in the good faith determination of the Trustee, may
         be unduly  prejudicial  to rights  Holders not joining in the giving of
         such direction, and

                  (2) the Trustee may take any other action deemed proper by the
         Trustee which is not inconsistent with such direction.

                  SECTION 513.  Waiver of Past Defaults.

                  The Holders of not less than a majority in aggregate principal
amount of the  Outstanding  Notes may on behalf of the  Holders of all the Notes
waive any past default hereunder and its consequences, except a default
<PAGE>
                                       56

                  (1) in respect of the payment of the  principal of (or premium
         or Liquidated Damages, if any) or interest on any Note, or

                  (2) in respect of a covenant or  provision  hereof which under
         Article  Nine cannot be modified or amended  without the consent of the
         Holder of each Outstanding Note affected.

                  Upon any such waiver,  such default shall cease to exist,  and
any Event of Default arising  therefrom shall be deemed to have been cured,  for
every  purpose  of  this  Indenture;  but no such  waiver  shall  extend  to any
subsequent or other  default or Event of Default or impair any right  consequent
thereon.

                  SECTION 514.  Waiver of Stay or Extension Laws.

                  The Company  covenants  (to the extent that it may lawfully do
so) that it shall  not at any time  insist  upon,  or  plead,  or in any  manner
whatsoever  claim or take the benefit or advantage of, any stay or extension law
wherever  enacted,  now or at any time hereafter in force,  which may affect the
covenants or the performance of this  Indenture;  and the Company (to the extent
that it may lawfully do so) hereby  expressly waives all benefit or advantage of
any such law and  covenants  that it  shall  not  hinder,  delay or  impede  the
execution  of any power  herein  granted to the  Trustee,  but shall  suffer and
permit the execution of every such power as though no such law had been enacted.

                                   ARTICLE SIX

                                   THE TRUSTEE

                  SECTION 601.  Notice of Defaults.

                  Within 90 days after the  occurrence of any Default  hereunder
known to the Trustee, the Trustee shall transmit in the manner and to the extent
provided in TIA Section 313(c), notice of such Default hereunder of the Trustee,
unless such Default shall have been cured or waived;  provided,  however,  that,
except in the case of a Default in the payment of the  principal of (or premium,
if any) or interest on any Note,  the Trustee shall be protected in  withholding
such notice if and so long as the board of directors, the executive committee or
a trust  committee of directors  and/or  Responsible  Officers of the Trustee in
good faith  determines that the withholding of such notice is in the interest of
the  Holders;  and  provided  further  that in the  case of any  Default  of the
character  specified in Section 501(7), no such notice to Holders shall be given
until at least 30 days after the occurrence thereof.

<PAGE>
                                       57

                  In case an Event of Default has  occurred  and is  continuing,
the Trustee  shall  exercise  such of the rights and powers vested in it by this
Indenture,  and use the same  degree of care and skill in their  exercise,  as a
prudent person would exercise or use under the  circumstances  in the conduct of
his or her own affairs.

         Trustee (unless other evidence be herein specifically  prescribed) may,
         in the  absence  of bad  faith on its  part,  require  and rely upon an
         Officer's Certificate;

         indemnity  against any loss,  expenses and  liabilities  which might be
         incurred by it in compliance with such request or direction;

                  (6) the Trustee  shall not be bound to make any  investigation

         express trust);

                  (2)  except  as  otherwise   expressly   provided  herein,  to
         reimburse  the Trustee  upon its request for all  reasonable  expenses,
         disbursements   and  advances  incurred  or  made  by  the  Trustee  in
         accordance  with any  provision of this  Indenture and under the Pledge
         Agreement  (including the reasonable  compensation and the expenses and
         disbursements  of its agents  and  counsel),  except any such  expense,
         disbursement or advance as may be attributable to its gross  negligence
         or bad faith; and

                  (3) to  indemnify  the  Trustee and its  officers,  directors,
         employees,  attorneys-in-fact  and agents for,  and to hold it harmless
         against,   any  loss,  liability  or  expense  incurred  without  gross
         negligence  or bad faith on its part,  arising out of or in  connection
         with the acceptance and  administration  of its duties under the Pledge
         Agreement or the acceptance or administration of this trust,  including
         the costs and expenses of defending

<PAGE>
                                       60

         itself  against any claim or liability in connection  with the exercise
         or performance of any of its powers or duties hereunder.

                  The   obligations   of  the  Company  under  this  Section  to
compensate  the  Trustee,   to  pay  or  reimburse  the  Trustee  for  expenses,
disbursements  and advances and to indemnify and hold harmless the Trustee shall
constitute additional  indebtedness  hereunder and shall survive the resignation
or removal of the Trustee and the  satisfaction and discharge of this Indenture.
As security for the performance of such obligations of the Company,  the Trustee
shall  have a claim  prior to the Notes  upon all  property  and  funds  held or
collected by the Trustee as such,  except funds held in trust for the payment of
principal of (and premium, if any) or interest on particular Notes.

                  When the  Trustee  incurs  expenses  or  renders  services  in
connection  with an Event of Default  specified  in Section  501(8) or (9),  the
expenses  (including the reasonable  charges and expenses of its counsel) of and
the  compensation  for such  services  are  intended to  constitute  expenses of
administration  under any applicable federal or state bankruptcy,  insolvency or
other similar law; provided,  however,  that if any such amounts are not paid as
expenses  of  administration,  they may be  collected  by the Trustee as amounts
payable to it pursuant to Section 506.

                  The   provisions   of  this  Section  606  shall  survive  the
termination of this Indenture.

                  SECTION 607.  Corporate Trustee Required; Eligibility.

                  There shall be at all times a Trustee hereunder which shall be
eligible to act as Trustee under TIA Section 310(a)(1) and shall have a combined
capital  and  surplus of at least $50  million.  If such  corporation  publishes
reports of condition at least annually,  pursuant to law or to the  requirements
of federal, state,  territorial or District of Columbia supervising or examining
authority,  then for the  purposes of this  Section,  the  combined  capital and
surplus  of such  corporation  shall be deemed to be its  combined  capital  and
surplus as set forth in its most recent report of condition so published.  If at
any  time  the  Trustee  shall  cease  to be  eligible  in  accordance  with the
provisions  of this Section 607, it shall resign  immediately  in the manner and
with the effect hereinafter specified in this Article.

                  SECTION  608.   Resignation   and  Removal;   Appointment   of
Successor.

                  (a)  No   resignation   or  removal  of  the  Trustee  and  no
appointment  of a  successor  Trustee  pursuant  to this  Article  shall  become
effective  until the  acceptance  of  appointment  by the  successor  Trustee in
accordance with the applicable requirements of Section 609.

<PAGE>
                                       61

                  (b) The  Trustee  may  resign  at any time by  giving  written
notice  thereof to the Company.  If the  instrument of acceptance by a successor
Trustee  required  by Section 609 shall not have been  delivered  to the Trustee
within 30 days after the giving of such  notice of  resignation,  the  resigning
Trustee may petition any court of competent  jurisdiction for the appointment of
a successor Trustee.

                  (c)  The  Trustee  may be  removed  at any  time by Act of the
Holders  of not less  than a  majority  in  aggregate  principal  amount  of the
Outstanding Notes, delivered to the Trustee and to the Company.

                  (d)      If at any time:

                  (1) the Trustee  shall fail to comply with the  provisions  of
         TIA Section 310(b) after written request  therefor by the Company or by
         any Holder  who has been a bona fide  Holder of a Note for at least six
         months, or

                  (2) the Trustee  shall cease to be eligible  under Section 607
         and shall fail to resign after written request  therefor by the Company
         or by any Holder who has been a bona fide Holder of a Note for at least
         six months, or

                  (3) the Trustee  shall become  incapable of acting or shall be
         adjudged a bankrupt or insolvent or a receiver of the Trustee or of its
         property  shall be appointed or any public officer shall take charge or
         control of the Trustee or of its property or affairs for the purpose of
         rehabilitation, conservation or liquidation,

then, in any such case, (i) the Company,  by a Board Resolution,  may remove the
Trustee,  or (ii) subject to TIA Section 315(e),  any Holder who has been a bona
fide  Holder of a Note for at least six months may, on behalf of himself and all
others similarly situated,  petition any court of competent jurisdiction for the
removal of the Trustee and the appointment of a successor Trustee.

                  (e)  If  the  Trustee  shall  resign,  be  removed  or  become
incapable  of acting,  or if a vacancy  shall occur in the office of Trustee for
any  cause,  the  Company,  by a Board  Resolution,  shall  promptly  appoint  a
successor  Trustee.  If,  within  one year after  such  resignation,  removal or
incapability,  or the occurrence of such vacancy,  a successor  Trustee shall be
appointed by Act of the Holders of a majority in aggregate  principal  amount of
the  Outstanding  Notes delivered to the Company and the retiring  Trustee,  the
successor  Trustee so appointed  shall,  forthwith  upon its  acceptance of such
appointment,  become the successor  Trustee and supersede the successor  Trustee
appointed by the Company.  If no successor  Trustee shall have been so appointed
by the Company or the Holders and accepted appointment in the manner hereinafter
provided, any Holder who has been a bona fide Holder of a Note for at least

<PAGE>
                                       62

six months may, on behalf of himself and all others similarly situated, petition
any court of competent jurisdiction for the appointment of a successor Trustee.

                  (f) The Company shall give notice of each resignation and each
removal  of the  Trustee  and each  appointment  of a  successor  Trustee to the
Holders in the manner provided for in Section 106. Each notice shall include the
name of the successor Trustee and the address of its Corporate Trust Office.

                  SECTION 609.  Acceptance of Appointment by Successor.

                  Every  successor  Trustee  appointed  hereunder shall execute,
acknowledge and deliver to the Company and to the retiring Trustee an instrument
accepting  such  appointment,  and thereupon the  resignation  or removal of the
retiring Trustee shall become effective and such successor Trustee,  without any
further  act,  deed or  conveyance,  shall  become  vested  with all the rights,
powers,  trusts  and  duties of the  retiring  Trustee;  but,  on request of the
Company or the successor  Trustee,  such retiring Trustee shall, upon payment of
its charges,  execute and deliver an instrument  transferring  to such successor
Trustee all the rights, powers and trusts of the retiring Trustee and shall duly
assign,  transfer and deliver to such  successor  Trustee all property and money
held by such  retiring  Trustee  hereunder.  Upon request of any such  successor
Trustee,  the Company shall execute any and all  instruments  for more fully and
certainly  vesting in and confirming to such successor  Trustee all such rights,
powers and trusts.

                  No successor  Trustee shall accept its  appointment  unless at
the time of such  acceptance  such  successor  Trustee  shall be  qualified  and
eligible under this Article.

                  SECTION 610. Merger,  Conversion,  Consolidation or Succession
to Business.

                  Any  corporation  into  which  the  Trustee  may be  merged or
converted or with which it may be  consolidated,  or any  corporation  resulting
from any merger,  conversion  or  consolidation  to which the Trustee shall be a
party,  or  any  corporation  succeeding  to  all  or  substantially  all of the
corporate  trust business of the Trustee,  shall be the successor of the Trustee
hereunder  (provided such corporation shall be otherwise  qualified and eligible
under this Article), without the execution or filing of any paper or any further
act on the part of any of the parties hereto.  In case any Notes shall have been
authenticated,  but not delivered,  by the Trustee then in office, any successor
by merger,  conversion or consolidation to such authenticating Trustee may adopt
such  authentication and deliver the Notes so authenticated with the same effect
as if such successor  Trustee had itself  authenticated  such Notes.  In case at
that time any of the Notes  shall not have  been  authenticated,  any  successor
Trustee  may  authenticate  such  Notes  either  in the name of any  predecessor
hereunder  or in the  name of the  successor  Trustee.  In all such  cases  such
certificates  shall have the full force and effect which this Indenture provides
for the certificate of authentication of the Trustee shall have; provided,
<PAGE>
                                       63

however,  that the  right to adopt  the  certificate  of  authentication  of any
predecessor  Trustee  or to  authenticate  Notes in the name of any  predecessor
Trustee shall apply only to its successor or successors by merger, conversion or
consolidation.

of the Company into, any other  corporation,  or upon any  conveyance,  lease or
transfer  of the  property of the  Company  substantially  as an entirety to any
other  Person,  any  property or assets of the Company  would  thereupon  become

                  (x) modify any  provisions of this Section 902 or Sections 513
         and 1022,  except to increase the  percentage  or  aggregate  principal
         amount of  Outstanding  Notes the consent of whose holders is necessary
         for waiver of compliance with this Indenture or to provide that certain
         other provisions of this Indenture cannot be modified or waived without
         the consent of the Holder of each Outstanding Note affected thereby.

                  It shall not be  necessary  for any Act of Holders  under this
Section to approve the particular form of any proposed  supplemental  indenture,
but it shall be sufficient if such Act shall approve the substance thereof.

to receive,  and shall be fully protected in relying upon, an Opinion of Counsel
stating that the  execution of such  supplemental  indenture  is  authorized  or

enter into any such  supplemental  indenture  which  affects  the  Trustees  own
rights, duties or immunities under this Indenture or otherwise.

                  SECTION 904.  Effect of Supplemental Indentures.

Company, to any such supplemental  indenture may be prepared and executed by the
Company and upon Company  Order  authenticated  and  delivered by the Trustee in
exchange for Outstanding Notes.

                  SECTION 907.  Notice of Supplemental Indentures.

                  Promptly after the execution by the Company and the Trustee of

Company  shall give  notice  thereof to the  Holders  of each  Outstanding  Note
affected  thereby,  in the manner provided for in Section 106,  setting forth in
general terms the substance of such supplemental indenture.

                                   ARTICLE TEN

                                    COVENANTS

                  SECTION  1001.  Payment of  Principal,  Premium,  if Any,  and
Interest.

                  The  Company  covenants  and  agrees  for the  benefit  of the
Holders that it shall duly and punctually pay the principal of (and premium,  if
any) and interest (and  Liquidated  Damages,  if any) on the Notes in accordance
with the terms of the Notes and this Indenture.

                  SECTION 1002.  Maintenance of Office or Agency.

                  The Company shall maintain, in The City of New York, an office
or agency  where  Notes may be  surrendered  for  registration  of  transfer  or
exchange and where  notices and demands to or upon the Company in respect of the
Notes and this Indenture may be served.  The office of the Trustee located at 40
Broad  Street,  5th Floor,  Suite 550,  New York,  New York 10004  shall be such
office or agency of the Company, unless the Company shall designate and maintain
some other office or agency for one or more of such purposes.  In addition,  the
Company  shall  maintain an office or agency where the Notes may be presented or
surrendered  for  payment  (which  shall be the  Corporate  Trust  Office of the
Trustee,  unless the Company  shall  designate and maintain some other office or
agency for one or more such  purposes).  The Company  shall give prompt  written
notice to the  Trustee  of any  change  in the  location  of any such  office or
agency.  If, at any time,  the Company  shall fail to maintain any such required
office or agency or shall fail to furnish the Trustee with the address  thereof,
such presentations, surrenders, notices and demands may be made or served at the
Corporate  Trust  Office of the  Trustee,  and the Company  hereby  appoints the
Trustee as its agent to receive all such presentations,  surrenders, notices and
demands.

                  The Company may also from time to time  designate  one or more
other offices or agencies  where the Notes may be presented or  surrendered  for
any or all such purposes and may from time to time rescind any such designation;
provided,  however,  that no such  designation or rescission shall in any manner
relieve  the  Company of its  obligation  to maintain an office or agency in The
City of New York for such purposes. The Company shall give prompt written
<PAGE>
                                       71

notice to the Trustee of any such  designation  or rescission  and any change in
the location of any such other office or agency.

                  SECTION 1003.  Money for Note Payments to Be Held in Trust.

                  If the  Company  shall,  at any  time,  act as its own  Paying
Agent,  it shall,  on or before each due date of the principal of (or premium or
Liquidated Damages, if any) or interest on any of the Notes,  segregate and hold
in trust for the benefit of the Persons entitled thereto a sum sufficient to pay
the  principal  of (or  premium or  Liquidated  Damages,  if any) or interest so
becoming due until such sums shall be paid to such Persons or otherwise disposed
of as herein  provided and shall  promptly  notify the Trustee in writing of its
action or failure so to act.

                  Whenever the Company  shall have one or more Paying Agents for
the Notes, it shall, on or before each due date of the principal of (or premium,
if any) or interest (or Liquidated Damages, if any) on any Notes, deposit with a
Paying Agent a sum  sufficient to pay the principal  (and premium and Liquidated
Damages,  if any) or interest so becoming  due, such sum to be held in trust for
the benefit of the Persons entitled to such principal,  premium or interest, and
(unless such Paying Agent is the Trustee) the Company shall promptly  notify the
Trustee in writing of such action or any failure so to act.

                  The  Company  shall cause each  Paying  Agent  (other than the
Trustee)  to execute  and  deliver to the  Trustee an  instrument  in which such
Paying Agent shall agree with the  Trustee,  subject to the  provisions  of this
Section 1003, that such Paying Agent shall:

                  (1) hold all sums held by it for the payment of the  principal
         of (and premium and Liquidated Damages, if any) or interest on Notes in
         trust for the benefit of the Persons  entitled  thereto until such sums
         shall  be paid to such  Persons  or  otherwise  disposed  of as  herein
         provided;

                  (2) give the  Trustee  written  notice of any  default  by the
         Company  (or any other  obligor  upon the  Notes) in the  making of any
         payment of principal (and premium,  if any) or interest (and Liquidated
         Damages, if any) on the Notes; and

                  (3) at any time during the  continuance  of any such  default,
         upon the written  request of the Trustee,  forthwith pay to the Trustee
         all sums so held in trust by such Paying Agent.

                  The Company may at any time,  for the purpose of obtaining the
satisfaction  and discharge of this Indenture or for any other purpose,  pay, or
by Company Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Company or such Paying  Agent,  such sums to be held by the Trustee
upon the same terms as those upon which such sums
<PAGE>
                                       72

were held by the Company or such Paying  Agent;  and,  upon such  payment by any
Paying  Agent to the  Trustee,  such Paying  Agent  shall be  released  from all
further liability with respect to such sums.

                  Any money  deposited with the Trustee or any Paying Agent,  or
then held by the  Company,  in trust for the  payment  of the  principal  of (or
premium or  Liquidated  Damages,  if any) or interest on any Note and  remaining
unclaimed for two years after such  principal,  premium,  interest or Liquidated
Damages  has  become  due and  payable  shall be paid to the  Company on Company
Request,  or (if then held by the Company) shall be discharged  from such trust;
and the Holder shall thereafter,  as an unsecured general creditor, look only to
the Company for payment thereof, and all liability of the Trustee or such Paying
Agent with  respect to such trust  money,  and all  liability  of the Company as
trustee thereof, shall thereupon cease;  provided,  however, that the Trustee or
such Paying Agent, before being required to make any such repayment,  may at the
expense of the Company cause to be published  once, in a newspaper  published in
the English language,  customarily published on each Business Day and of general
circulation in the Borough of Manhattan,  The City of New York, notice that such
money remains  unclaimed and that, after a date specified  therein,  which shall
not be less  than 30 days  from  the  date of such  publication,  any  unclaimed
balance of such money then remaining shall be repaid to the Company.

                  SECTION 1004.  Corporate Existence.

                  Subject to Article Eight and the  Reorganization,  the Company
shall do or cause to be done all things  necessary  to preserve and keep in full
force and effect the corporate  existence,  rights  (charter and  statutory) and
franchises of the Company and each Significant  Subsidiary;  provided,  however,
that the Company  shall not be required to preserve  any such right or franchise
if the Board of Directors  shall determine that the  preservation  thereof is no
longer  desirable  in  the  conduct  of the  business  of the  Company  and  its
Subsidiaries as a whole and that the loss thereof is not  disadvantageous in any
material respect to the Holders.

                  SECTION 1005.  Payment of Taxes and Other Claims.

                  The  Company  shall  pay or  discharge  or cause to be paid or
discharged,  before the same shall become delinquent, (a) all taxes, assessments
and governmental charges levied or imposed upon the Company or any Subsidiary or
upon the income,  profits or property of the Company or any  Subsidiary  and (b)
all lawful claims for labor, materials and supplies,  which, if unpaid, would be
expected to by law become a lien (other than a Permitted Lien) upon the property
of the Company or any Subsidiary;  provided, however, that the Company shall not
be required to pay or discharge or cause to be paid or discharged  any such tax,
assessment,  charge or claim whose  amount,  applicability  or validity is being
contested in good faith by appropriate proceedings.

                  The Company shall cause all properties owned by the Company or
any  Subsidiary  or used or held for use in the  conduct of its  business or the
business of any Subsidiary to be maintained and kept in good  condition,  repair
and working order and supplied  with all necessary  equipment and shall cause to
be  made  all  necessary  repairs,  renewals,   replacements,   betterments  and
improvements  thereof, all as in the judgment of the Company may be necessary so
that the  business  carried  on in  connection  therewith  may be  properly  and
advantageously  conducted at all times; provided,  however, that nothing in this
Section shall prevent the Company from  discontinuing  the maintenance of any of
such  properties  if such  discontinuance  is, in the  judgment of the  Company,
desirable in the conduct of its business or the business of any  Subsidiary  and
not disadvantageous in any material respect to the Holders.

                  SECTION 1007.  Insurance.

                  The  Company  shall  at all  times  keep  all of its  and  its
Subsidiaries  properties which are of an insurable nature insured with insurers,
believed by the Company to be responsible,  against loss or damage to the extent
that  property  of similar  character  is  usually  so  insured by  corporations
similarly situated and owning like properties.

                  (a) The Company shall deliver to the Trustee,  within 120 days

be determined  without  regard to any period of grace or  requirement  of notice
under this Indenture.

                  (b) When any Default has occurred and is continuing under this
Indenture,  or if the  trustee  for or the  Holder  of  any  other  evidence  of
Indebtedness  of the  Company  or any  Subsidiary  gives any notice or takes any
other  action with  respect to a claimed  default  (other  than with  respect to
Indebtedness in the principal  amount of less than $1,000,000) the Company shall
deliver to the Trustee by registered or certified mail or by telegram,  telex or
facsimile transmission an Officer's Certificate specifying such event, notice or
other action within five Business Days of its occurrence.

                  (c)  When  any   Registration   Default  (as  defined  in  the
Registration  Rights Agreement) occurs, the Company shall immediately deliver to

covenant  will  not  apply  to  any of the  following  Indebtedness  ("Permitted
Indebtedness"), each of which shall be given independent effect:

                   (i)    Indebtedness of the Company evidenced by the Notes;

                  (ii) Indebtedness of the Company or any Restricted  Subsidiary

         integration) of Telecommunications Assets;

                   (v) Indebtedness of a Restricted  Subsidiary owed to and held
         by the Company or another  Restricted  Subsidiary,  except that (A) any
         transfer of such Indebtedness by the Company or a Restricted Subsidiary
         (other than to the Company or another  Restricted  Subsidiary)  and (B)
         the  sale,  transfer  or  other  disposition  by  the  Company  or  any
         Restricted Subsidiary of Capital Stock of a Restricted Subsidiary which
         is owed  Indebtedness by another  Restricted  Subsidiary shall, in each
         case, be an Incurrence of Indebtedness  by such Restricted  Subsidiary,
         subject to the other provisions of this Indenture;

                  (vi)  Indebtedness  of  the  Company  owed  to and  held  by a

         this Indenture and the Notes,  except that the limitations of paragraph
         (a) of this Section 1011 shall apply to such  Indebtedness at such time
         as (A) any transfer of such  Indebtedness  by a  Restricted  Subsidiary
         (other  than to  another  Restricted  Subsidiary)  and  (B)  the  sale,
         transfer  or  other  disposition  by  the  Company  or  any  Restricted
         Subsidiary  of Capital Stock of a Restricted  Subsidiary  which is owed
         such  Indebtedness by the Company,  subject to other provisions of this

         amount so refinanced or refunded (plus premiums,  accrued  interest and
         reasonable  fees and  expenses);  provided  that such new  Indebtedness
         shall only be  permitted  under this  clause  (vii) if: (A) in case the
         Notes are  refinanced in part or the  Indebtedness  to be refinanced is
         pari passu with the Notes,  such new  Indebtedness,  by its terms or by
         the terms of any  agreement  or  instrument  pursuant to which such new
         Indebtedness is issued or remains  outstanding,  is expressly made pari
         passu with, or subordinate in right of payment to, the remaining Notes,
         (B) in case the  Indebtedness to be refinanced is subordinated in right
         of payment to the Notes, such new Indebtedness,  by its terms or by the
         terms  of any  agreement  or  instrument  pursuant  to  which  such new
         Indebtedness  is issued  or  remains  outstanding,  is  expressly  made
         subordinate  in right of  payment  to the Notes at least to the  extent
         that the Indebtedness to be refinanced is subordinated to the Notes and
         (C) such new  Indebtedness,  determined as of the date of Incurrence of
         such new Indebtedness,  does not mature prior to the Stated Maturity of
         the Indebtedness to be refinanced or refunded,  and the Average Life of
         such new  Indebtedness is at least equal to the remaining  Average Life
         of the Indebtedness to be refinanced or refunded;  and provided further
         that in no event may Indebtedness of the Company be refinanced by means
         of any  Indebtedness  of any  Restricted  Subsidiary  pursuant  to this
         clause (vii);

                  (viii)  Indebtedness of (x) the Company not to exceed,  at any

         issuance and sale,  other than to a Subsidiary,  of Common Stock (other
         than Redeemable Stock) of the Company (less the amount of such proceeds
         used to make Restricted Payments as provided in clause (iii) or (iv) of
         the  second  paragraph  of  Section  1012) and (y) the  Company  not to
         exceed,  at  one  time  outstanding,  the  fair  market  value  of  any
         Telecommunications  Assets  acquired  by the  Company in  exchange  for
         Common  Stock of the Company  issued  after the Issue  Date;  provided,
         however,  that  in  determining  the  fair  market  value  of any  such
         Telecommunications  Assets so acquired,  if the  estimated  fair market
         value of such  Telecommunications  Assets  exceeds (A) $2.0 million (as
         estimated  in good  faith  by the  Board of  Directors),  then the fair
         market value of such Telecommunications  Assets will be determined by a
         majority of the Board of Directors of the Company,  which determination
         will be evidenced by a resolution  thereof,  and (B) $10.0  million (as
         estimated  in good faith by the Board of  Directors),  then the Company
         shall deliver to the Trustee a written  appraisal as to the fair market
         value  of  such  Telecommunications  Assets  prepared  by a  nationally
         recognized investment banking or public accounting firm (or, if no such
         investment  banking or public  accounting  firm is qualified to prepare
         such an appraisal,  by a nationally  recognized  appraisal  firm);  and
         provided  further that,  except with respect to Acquired  Indebtedness,
         such Indebtedness does not mature prior to the
<PAGE>
                                       80

         Stated Maturity of the Notes and the Average Life of  such Indebtedness
         is longer than  that of the Notes;

                  (ix) Indebtedness of the Company or any Restricted  Subsidiary
         (A) in respect  of  performance,  surety or appeal  bonds or letters of

         course of business,  (B) under  Currency  Agreements  and Interest Rate
         Agreements  covering  Indebtedness  of the Company;  provided that such
         agreements do not increase the Indebtedness of the obligor  outstanding
         at any time other than as a result of fluctuations in foreign  currency
         exchange rates or interest rates or by reason of fees,  indemnities and
         compensation   payable  thereunder  and  (C)  arising  from  agreements
         providing for indemnification,  adjustment of purchase price or similar
         obligations,  or from Guarantees or letters of credit,  surety bonds or
         performance bonds securing any obligations of the Company or any of its
         Restricted  Subsidiaries  pursuant  to  such  agreements,  in any  case
         Incurred in connection with the disposition of any business,  assets or
         Restricted   Subsidiary  of  the  Company  (other  than  Guarantees  of
         Indebtedness  Incurred  by any Person  acquiring  all or any portion of
         such  business,  assets or  Restricted  Subsidiary  for the  purpose of
         financing such  acquisition),  in a principal  amount not to exceed the
         gross  proceeds  actually  received  by the  Company or any  Restricted
         Subsidiary in connection with such disposition;

                   (x)  Indebtedness of the Company,  to the extent that the net
         proceeds  thereof are promptly (A) used to repurchase Notes tendered in
         a Change of Control  Offer or (B) deposited to defease all of the Notes
         pursuant to Article Thirteen;

                  (xi) Indebtedness of a Restricted Subsidiary  represented by a
         Guarantee of the Notes permitted by and made in accordance with Section
         1018; and

                  (xii) Indebtedness of the Company or any Restricted Subsidiary
         in addition to that  permitted  to be incurred  pursuant to clauses (i)
         through  (xi) above in an aggregate  principal  amount not in excess of
         $10.0  million  (or,  to the extent not  denominated  in United  States
         dollars,  the United States Dollar Equivalent  thereof) at any one time
         outstanding.

                  (c) For  purposes  of  determining  any  particular  amount of
Indebtedness  under this Section 1011,  Guarantees,  Liens or  obligations  with
respect  to  letters  of  credit  and  other  credit   enhancements   supporting
Indebtedness  otherwise  included in the determination of such particular amount
shall not be included;  provided,  however,  that the foregoing shall not in any
way be  deemed  to limit  the  provisions  of  Section  1018.  For  purposes  of
determining  compliance  with this  Section  1011,  in the event that an item of
Indebtedness  meets the  criteria of more than one of the types of  Indebtedness
described in the above clauses,  the Company, in its sole discretion may, at the
time of such Incurrence, (i) classify such item of Indebtedness under and
<PAGE>
                                       81

comply  with either of  paragraph  (a) or (b) of this  covenant  (or any of such
definitions),  as applicable, (ii) classify and divide such item of Indebtedness
into more than one of such paragraphs (or definitions),  as applicable and (iii)
elect to comply with such  paragraphs  (or  definitions),  as  applicable in any
order.

                  SECTION 1012.  Limitation on Restricted Payments.

                  The  Company  shall not,  and shall not permit any  Restricted
Subsidiary to,  directly or  indirectly,  (i) (A) declare or pay any dividend or
make any  distribution in respect of the Company's  Capital Stock to the holders

options,  warrants or other rights to acquire  such shares of Capital  Stock) or
(B)  declare  or pay any  dividend  or make any  distribution  in respect of the

purchase,  redeem,  retire or otherwise  acquire for value any shares of Capital
Stock of the Company  (including  options,  warrants or other  rights to acquire
such shares of Capital  Stock) held by any Person or any shares of Capital Stock

acquire  such  shares of Capital  Stock)  held by any  Affiliate  of the Company
(other  than a  wholly  owned  Restricted  Subsidiary)  or any  holder  (or  any
Affiliate  thereof) of 5.0% or more of the Company's  Capital Stock;  (iii) make
any  voluntary  or  optional  principal   payment,   or  voluntary  or  optional
redemption,  repurchase,  defeasance,  or other  acquisition  or retirement  for
value,  of  Indebtedness of the Company that is subordinated in right of payment
to the Notes; or (iv) make any Investment, other than a Permitted Investment, in
any Person (such payments or any other actions  described in clauses (i) through
(iv) being  collectively  "Restricted  Payments")  if, at the time of, and after
giving effect to, the proposed Restricted Payment:

                          (A) a Default or Event of Default  shall have occurred
                          and be continuing;

                          (B) the  Company  could  not  Incur at least  $1.00 of
                          Indebtedness under paragraph (a) of Section 1011; and

                          (C) the aggregate  amount of all  Restricted  Payments
                          declared or made from and after the Closing Date would
                          exceed the sum of:

                               (1)  Cumulative  Consolidated   Cash  Flow  minus
                          200.0% of Cumulative Consolidated Fixed Charges;

                               (2)  100.0% of the  aggregate  Net Cash  Proceeds
                          from  the  issue or sale to a  Person,  which is not a
                          Subsidiary of the Company, of Capital Stock of

<PAGE>
                                       82

                          the Company (other than  Redeemable  Stock) or of debt
                          securities  of the Company  which have been  converted
                          into or exchanged  for such Capital  Stock  (except to
                          the extent  such Net Cash  Proceeds  are used to Incur
                          new Indebtedness outstanding pursuant to clause (viii)
                          of paragraph (b) of Section 1011); and

                               (3) to the extent any Permitted  Investment  that
                          was made  after the  Closing  Date is sold for cash or
                          otherwise liquidated or repaid for cash, the lesser of
                          (i) the cash  return of capital  with  respect to such
                          Permitted Investment (less the cost of disposition, if
                          any) and (ii) the  initial  amount  of such  Permitted
                          Investment.

                  The  foregoing  provision  shall not be violated by reason of:
(i) the  payment of any  dividend  within 60 days after the date of  declaration
thereof if, at said date of  declaration,  such  payment  would  comply with the
foregoing  paragraph;  (ii)  the  redemption,  repurchase,  defeasance  or other
acquisition  or retirement for value of  Indebtedness  that is  subordinated  in
right of payment to the Notes  including  a premium,  if any,  and  accrued  and
unpaid interest and Liquidated  Damages, if any, with the net proceeds of, or in
exchange  for,  Indebtedness  Incurred  under clause  (viii) of paragraph (b) of
Section 1011; (iii) the repurchase,  redemption or other  acquisition of Capital
Stock of the  Company in  exchange  for,  or out of the Net Cash  Proceeds  of a
substantially concurrent (A) capital contribution to the Company or (B) issuance
and sale of shares of Capital Stock (other than Redeemable Stock) of the Company
(except  to the  extent  such  proceeds  are  used  to  incur  new  Indebtedness
outstanding  pursuant to clause (viii) of paragraph (b) of Section  1011);  (iv)
the acquisition of Indebtedness of the Company which is subordinated in right of
payment to the Notes in exchange for, or out of the proceeds of, a substantially
concurrent (A) capital  contribution  to the Company or (B) issuance and sale of
shares of the Capital Stock of the Company (other than Redeemable Stock) (except
to the  extent  such  proceeds  are used to incur new  Indebtedness  outstanding
pursuant to clause  (viii) of paragraph  (b) of Section  1011);  (v) payments or
distributions  to dissenting  stockholders  in accordance  with  applicable law,
pursuant to or in connection with a consolidation,  merger or transfer of assets
that complies with Article Eight;  (vi) other Restricted  Payments not to exceed
$2.0 million; and (vii) investments in any Telecommunications Assets acquired in
exchange for Capital Stock of the Company (other than  Redeemable  Stock) issued
after the Issue Date or with the Net Cash Proceeds from the concurrent  issuance
and sale of Capital Stock of the Company (other than Redeemable Stock); provided
that,  except in the case of clause  (i),  no Default or Event of Default  shall
have  occurred and be  continuing  or occur as a  consequence  of the actions or
payments set forth therein.

                  Each Restricted  Payment permitted pursuant to the immediately
preceding  paragraph  (other than the Restricted  Payment  referred to in clause
(ii) thereof) and the Net Cash Proceeds  from any capital  contributions  to the
Company or issuance of Capital Stock referred to




<PAGE>
                                       83

in clauses (iii), (iv) and (vii) of the immediately  preceding paragraph,  shall
be included in  calculating  whether the  conditions  of clause (C) of the first
paragraph  of this  Section  1012 have been met with  respect to any  subsequent
Restricted  Payments.  In the event the proceeds of an issuance of Capital Stock
of the Company are used for the redemption,  repurchase or other  acquisition of
the Notes,  then the Net Cash  Proceeds  of such  issuance  shall be included in
clause (C) of the first  paragraph  of this Section 1012 only to the extent such
proceeds are not used for such  redemption,  repurchase or other  acquisition of
the Notes.

                  SECTION  1013.   Limitation  on  Dividend  and  Other  Payment
Restrictions Affecting Restricted Subsidiaries.

                  So long as any of the Notes are Outstanding, the Company shall
not,  and shall not permit any  Restricted  Subsidiary  to,  create or otherwise
cause or suffer to exist or  become  effective  any  consensual  encumbrance  or
restriction  of any kind on the ability of any  Restricted  Subsidiary to do any
one of the following:

                  (i) pay  dividends  or make  any  other  distributions  on any
         Capital Stock of such Restricted Subsidiary owned by the Company or any
         other Restricted Subsidiary;

                  (ii) pay any  Indebtedness  owed to the  Company  or any other
         Restricted Subsidiary;

                  (iii)  make  loans or  advances  to the  Company  or any other
         Restricted Subsidiary; or

                  (iv)  transfer any of its property or assets to the Company or
         any other Restricted Subsidiary.

                  The foregoing  provisions  shall not restrict any encumbrances
         or restrictions:

                  (i)existing on the Closing Date in this Indenture or any other
         agreements  or  instruments  in effect  on the  Closing  Date,  and any
         extensions,  refinancings, renewals or replacements of such agreements;
         provided that the encumbrances and restrictions in any such extensions,
         refinancings,  renewals or  replacements  are no less  favorable in any
         material respect to the Holders than those encumbrances or restrictions
         that  are then in  effect  and that  are  being  extended,  refinanced,
         renewed or replaced;

                  (ii)  contained  in  the  terms  of  any  Indebtedness  or any
         agreement  pursuant to which such  Indebtedness  was issued (or, in the
         case of Acquired  Preferred  Stock,  terms of such  Acquired  Preferred
         Stock) if the encumbrance or restriction applies only in the event of a
         default  with  respect  to  a  financial  covenant  contained  in  such
         Indebtedness or




<PAGE>
                                       84

         agreement  (or,  in the  case of  Acquired  Preferred  Stock,  upon the
         default in the payment of dividends upon such Acquired Preferred Stock)
         and  such   encumbrance  or   restriction   is  not   materially   more
         disadvantageous   to  the  Holders  than  is  customary  in  comparable
         financings  (as  determined by the Company) and the Company  determines
         that any such encumbrance or restriction will not materially affect the
         Company's ability to make principal or interest payments on the Notes;

                  (iii) existing under or by reason of applicable law;

                  (iv)  existing  with  respect to any Person or the property or
         assets  of  such  Person  acquired  by the  Company  or any  Restricted
         Subsidiary,  existing at the time of such  acquisition and not incurred
         in contemplation  thereof,  which  encumbrances or restrictions are not
         applicable  to any Person or the property or assets of any Person other
         than such Person or the property or assets of such Person so acquired;

                  (v) in the case of clause (iv) of the first  paragraph of this
         Section 1013, (A) that restrict in a customary  manner the  subletting,
         assignment  or transfer of any property or asset that is, or is subject
         to, a lease,  purchase  mortgage  obligation,  license,  conveyance  or
         contract or similar  property or asset,  (B)  existing by virtue of any
         transfer of, agreement to transfer, option or right with respect to, or
         Lien on,  any  property  or assets  of the  Company  or any  Restricted
         Subsidiary not otherwise prohibited by this Indenture or (C) arising or
         agreed to in the  ordinary  course of  business,  not  relating  to any
         Indebtedness,  and  that  do  not,  individually  or in the  aggregate,
         detract  from the value of  property  or assets of the  Company  or any
         Restricted  Subsidiary  in any manner  material  to the  Company or any
         Restricted Subsidiary; or

                  (vi) with  respect  to a  Restricted  Subsidiary  and  imposed
         pursuant to an  agreement  that has been  entered  into for the sale or
         disposition  of all or  substantially  all of the Capital  Stock of, or
         property and assets of, such Restricted Subsidiary.

                  Nothing  contained  in this  Section  1013 shall  prevent  the
Company or any Restricted Subsidiary from (1) creating,  incurring,  assuming or
suffering  to  exist  any  Liens  otherwise  permitted  in  Section  1016 or (2)
restricting  the sale or other  disposition of property or assets of the Company
or any of its Restricted Subsidiaries that secure Indebtedness of the Company or
any of its Restricted Subsidiaries.

                  SECTION  1014.  Limitation on the Issuance and Sale of Capital
Stock of Restricted Subsidiaries.

                  The  Company  shall not,  and shall not permit any  Restricted
Subsidiary,  directly or indirectly, to issue, transfer,  convey, sell, lease or
otherwise dispose of any shares of Capital

                                       85

Stock  (including  options,  warrants or other rights to purchase shares of such
Capital  Stock) of such or any other  Restricted  Subsidiary  (other than to the
Company or a wholly owned Restricted  Subsidiary or in respect of any director's
qualifying  shares or sales of  shares of  Capital  Stock to  foreign  nationals
mandated by applicable  law) to any Person unless (A) the Net Cash Proceeds from
such  issuance,  transfer,  conveyance,  sale,  lease or other  disposition  are
applied in accordance with Section 1017, (B) immediately  after giving effect to
such issuance,  transfer,  conveyance,  sale, lease or other  disposition,  such
Restricted Subsidiary would no longer constitute a Restricted Subsidiary and (C)
any  Investment in such Person  remaining  after giving effect to such issuance,
transfer, conveyance, sale, lease or other disposition would have been permitted
to be made under  Section 1012 if made on the date of such  issuance,  transfer,
conveyance,  sale,  lease  or  other  disposition  (valued  as  provided  in the
definition of "Investment"  contained in Section 101); provided,  however,  that
notwithstanding  the  foregoing,  the Company may, and may permit its Restricted
Subsidiaries to, issue,  transfer,  convey, sell or otherwise dispose of Capital
Stock (other than Redeemable Stock) (including options, warrants or other rights
to purchase shares of such Capital Stock) of such or any other  Restricted Cable
Subsidiary so long as (x) immediately after such transaction, the Company and/or
its Restricted  Subsidiaries continue to beneficially own at least a majority of
the  Voting  Stock  of such  Restricted  Cable  Subsidiary  and (y) the Net Cash
Proceeds from such  transaction are applied in accordance with the provisions of
Section 1017. For purposes of the  foregoing,  a "Restricted  Cable  Subsidiary"
shall mean any Restricted  Subsidiary of the Company organized after the Closing
Date  for  the  purpose  of  designing,  developing,  constructing,   acquiring,
licensing,  owning and/or  operating  fiber optic cable or similar  transmission
systems used in the telecommunications business.

                  SECTION 1015. Limitation on Transactions with Stockholders and
Affiliates.

                  The  Company  shall not,  and shall not permit any  Restricted
Subsidiary  to,  directly  or  indirectly,  enter  into,  renew  or  extend  any
transaction  (including,  without  limitation,  the  purchase,  sale,  lease  or
exchange of property or assets, or the rendering of any service) with any holder
(or any Affiliate of such holder) of 10.0% or more of any class of Capital Stock
of the Company or any Restricted Subsidiary or with any Affiliate of the Company
or any Restricted Subsidiary, unless the following conditions have been met:

                  (i)such  transaction or series of  transactions is on terms no
         less favorable to the Company or such Restricted  Subsidiary than those
         that could be obtained in a comparable arm's-length  transaction with a
         Person that is not such a holder or an Affiliate;

                  (ii) if such  transaction or series of  transactions  involves
         aggregate   consideration   in  excess  of  $2.0  million,   then  such
         transaction or series of  transactions is approved by a majority of the
         Board of Directors of the Company (including a majority
<PAGE>
                                       86

         of the  disinterested  members thereof,  if any)  and is evidenced by a
         resolution thereof; and

                  (iii) if such  transaction or series of transactions  involves
         aggregate consideration in excess of $10.0 million, then the Company or
         such  Restricted  Subsidiary  shall  deliver  to the  Trustee a written
         opinion as to the fairness to the Company or such Restricted Subsidiary
         of such  transaction  from a financial  point of view from a nationally
         recognized  investment  banking firm (or, if an investment banking firm
         is generally  not  qualified  to give such an opinion,  by a nationally
         recognized appraisal firm or accounting firm).

                  The foregoing limitation does not limit, and will not apply to
(i) any transaction  between the Company and any of its Restricted  Subsidiaries
or between or among Restricted  Subsidiaries;  (ii) the payment or reimbursement
of  reasonable  and  customary  regular  fees and  expenses to  directors of the
Company who are not employees of the Company;  (iii) any Restricted Payments not
prohibited by Section 1012;  (iv) loans and advances to officers or employees of
the Company and its  Subsidiaries not exceeding at any one time outstanding $1.5
million in the aggregate;  (v) employment  and similar  agreements  entered into
between the Company or any of its Restricted  Subsidiaries with their respective
employees in the ordinary  course of business;  and (vi)  operating  and similar
agreements entered into in the ordinary course of the Company's business.

                  SECTION 1016.  Limitation on Liens.

                  The  Company  shall not,  and shall not permit any  Restricted
Subsidiary to, directly or indirectly,  create, incur, assume or suffer to exist
any Lien (other than Permitted  Liens) on any of its assets or properties of any
character  (including,  without  limitation,  licenses and  trademarks),  or any
shares of Capital Stock or  Indebtedness of any Restricted  Subsidiary,  whether
owned at the date of this  Indenture  or  thereafter  acquired,  or any  income,
profits  or  proceeds  therefrom,  or assign or  otherwise  convey  any right to
receive income thereof,  without making effective provision for all of the Notes
and all other amounts  ranking pari passu with the Notes to be directly  secured
equally and ratably with the obligation or liability secured by such Lien or, if
such  obligation  or liability is  subordinated  to the Notes and other  amounts
ranking pari passu with the Notes,  without  making  provision for the Notes and
such other amounts to be directly  secured prior to the  obligation or liability
secured by such Lien.

                  SECTION 1017.  Limitation on Asset Sales.

                  The  Company  shall not,  and shall not permit any  Restricted
Subsidiary  to,  make any Asset Sale  unless (i) the  Company or the  Restricted
Subsidiary, as the case may be, receives consideration at the time of such Asset
Sale at least equal to the fair market value of the assets
<PAGE>
                                       87

sold or disposed  of as  determined  by the good faith  judgment of the Board of
Directors  evidenced  by a Board  Resolution  and  (ii) at  least  75.0%  of the
consideration  received for such Asset Sale consists of cash or cash equivalents
or the assumption of unsubordinated Indebtedness.

                  The  Company  shall,  or shall cause the  relevant  Restricted
Subsidiary  to,  within  360  days  after  the date of  receipt  of the Net Cash
Proceeds  from an Asset  Sale,  (i) (A) apply an  amount  equal to such Net Cash
Proceeds to  permanently  repay  unsubordinated  Indebtedness  of the Company or
Indebtedness of any Restricted Subsidiary, in each case, owing to a Person other
than the Company or any of its  Restricted  Subsidiaries  or (B) invest an equal
amount,  or the amount not so applied  pursuant  to clause  (A),  in property or
assets of a nature or type or that are used in a business (or in a Person having
property  and assets of a nature or type,  or engaged in a business)  similar or
related to the nature or type of the property and assets of, or the business of,
the  Company  and  its  Restricted  Subsidiaries  existing  on the  date of such
investment  (as  determined  in good  faith  by the  Board of  Directors,  whose
determination  shall be conclusive and evidenced by a Board Resolution) and (ii)
apply (no later  than the end of the  360-day  period  referred  to above)  such
excess Net Cash  Proceeds (to the extent not applied  pursuant to clause (i)) as
provided in the following  paragraphs  of this Section 1017.  The amount of such
Net Cash  Proceeds  required  to be applied (or to be  committed  to be applied)
during such 360-day period  referred to above in the preceding  sentence and not
applied  as so  required  by the end of such  period  shall  constitute  "Excess
Proceeds".

                  If, as of the first day of any calendar  month,  the aggregate
amount of Excess  Proceeds not  theretofore  subject to an Excess Proceeds Offer
(as defined  below) totals at least $10.0  million,  the Company must, not later
than the 30th  Business  Day  thereafter,  make an offer  (an  "Excess  Proceeds
Offer") to purchase from the Holders on a pro rata basis an aggregate  principal
amount of Notes equal to the Excess  Proceeds on such date, at a purchase  price
equal to 100.0%  of the  principal  amount of the  Notes,  plus,  in each  case,
accrued  and unpaid  interest  and  Liquidated  Damages,  if any, to the date of
purchase (the "Excess Proceeds Payment").

                  The Company shall commence an Excess Proceeds Offer by mailing
a notice to the Trustee and each Holder  stating:  (i) that the Excess  Proceeds
Offer is being made  pursuant to this  Section  1017 and that all Notes  validly
tendered  will be accepted  for payment on a pro rata basis;  (ii) the  purchase
price and the date of purchase (which shall be a Business Day no earlier than 30
days nor later than 60 days from the date such  notice is mailed)  (the  "Excess
Proceeds  Payment  Date");  (iii) that any Note not  tendered  will  continue to
accrue interest pursuant to its terms; (iv) that, unless the Company defaults in
the  payment of the Excess  Proceeds  Payment,  any Note  accepted  for  payment
pursuant  to the  Excess  Proceeds  Offer  shall  cease to accrue  interest  and
Liquidated  Damages,  if any, on and after the Excess Proceeds Payment Date; (v)
that Holders  electing to have a Note purchased  pursuant to the Excess Proceeds
Offer will be required to surrender  the Note,  together  with the form entitled
"Option of the Holder to Elect

<PAGE>
                                       88

Purchase" on the reverse side of the Note completed,  to the Paying Agent at the
address  specified  in the notice prior to the close of business on the Business
Day immediately  preceding the Excess  Proceeds  Payment Date; (vi) that Holders
shall be entitled to withdraw their election if the Paying Agent  receives,  not
later than the close of business on the third Business Day immediately preceding
the Excess Proceeds Payment Date, a telegram,  facsimile  transmission or letter
setting forth the name of such Holder,  the principal  amount of Notes delivered
for purchase  and a statement  that such Holder is  withdrawing  his election to
have  such  Notes  purchased;  and  (vii)  that  Holders  whose  Notes are being
purchased only in part will be issued new Notes equal in principal amount to the
unpurchased portion of the Notes surrendered;  provided that each Note purchased
and each new Note issued  shall be in a  principal  amount of $1,000 or integral
multiples thereof.

                  On the Excess  Proceeds  Payment  Date,  the Company shall (i)
accept for  payment  on a pro rata  basis  Notes or  portions  thereof  tendered
pursuant to the Excess Proceeds Offer;  (ii) deposit with the Paying Agent money
sufficient  to pay the  purchase  price of all  Notes  or  portions  thereof  so
accepted; and (iii) deliver, or cause to be delivered,  to the Trustee all Notes
or  portions  thereof  so  accepted  together  with  an  Officer's   Certificate
specifying  the Notes or portions  thereof  accepted for payment by the Company.
The Paying Agent shall promptly mail to the Holders of Notes so accepted payment
in an  amount  equal to the  purchase  price,  and the  Trustee  shall  promptly
authenticate  and mail to such Holders a new Note equal in  principal  amount to
any  unpurchased  portion  of the Note  surrendered;  provided  that  each  Note
purchased  and each new Note issued shall be in a principal  amount of $1,000 or
integral multiples thereof. To the extent that the aggregate principal amount of
Notes  tendered  is less  than the  Excess  Proceeds,  the  Company  may use any
remaining  Excess  Proceeds for general  corporate  purposes.  The Company shall
publicly  announce  the  results  of  the  Excess  Proceeds  Offer  as  soon  as
practicable after the Excess Proceeds Payment Date. For purposes of this Section
1017, the Trustee shall act as the Paying Agent.

                  The Company  shall  comply with Rule 14e-1 under the  Exchange
Act and any other rules and regulations  thereunder to the extent such rules and
regulations are applicable,  in the event that such Excess Proceeds are received
by the Company under this Section 1017 and the Company is required to repurchase
Notes as described above.

                  SECTION  1018.   Limitation  on  Issuances  of  Guarantees  of
Indebtedness by Restricted Subsidiaries.

                  The  Company  shall  not  permit  any  Restricted  Subsidiary,
directly or  indirectly,  to  Guarantee,  assume or in any other  manner  become
liable with respect to any Indebtedness of the Company,  other than Indebtedness
under Credit Facilities  incurred under clause (iii) of paragraph (b) in Section
1011, unless (i) such Restricted Subsidiary simultaneously executes and delivers
a  supplemental  indenture to this  Indenture  providing  for a Guarantee of the
Notes on

<PAGE>
                                       89

terms substantially  similar to the Guarantee of such Indebtedness,  except that
if such Indebtedness is by its express terms subordinated in right of payment to
the Notes, any such assumption,  Guarantee or other Liability of such Restricted
Subsidiary with respect to such  Indebtedness  shall be subordinated in right of
payment to such Restricted Subsidiary's assumption, Guarantee or other liability
with respect to the Notes  substantially to the same extent as such Indebtedness
is  subordinated to the Notes and (ii) such Restricted  Subsidiary  waives,  and
shall not in any manner  whatsoever  claim or take the benefit or advantage  of,
any  rights of  reimbursement,  indemnity  or  subrogation  or any other  rights
against  the  Company  or any  other  Restricted  Subsidiary  as a result of any
payment by such Restricted Subsidiary under its Guarantee.

                  Notwithstanding  the foregoing,  any Guarantee by a Restricted
Subsidiary  may  provide  by  its  terms  that  it  will  be  automatically  and
unconditionally released and discharged upon (i) any sale, exchange or transfer,
to any Person not an Affiliate of the Company,  of all of the Company's and each
Restricted  Subsidiary's  Capital Stock in, or all or  substantially  all of the
assets of, such Restricted  Subsidiary (which sale,  exchange or transfer is not
prohibited by this  Indenture) or (ii) the release or discharge of the guarantee
which resulted in the creation of such Guarantee,  except a discharge or release
by or as a result of payment under such Guarantee.

                  SECTION  1019.   Business  of  the  Company;   Restriction  on
Transfers of Existing Business.

                  The  Company  shall not,  and shall not permit any  Restricted
Subsidiary to, be  principally  engaged in any business or activity other than a
Permitted Business. In addition, the Company and any Restricted Subsidiary shall
not be  permitted  to,  directly or  indirectly,  transfer  to any  Unrestricted
Subsidiary (i) any of the material licenses, agreements or instruments,  permits
or  authorizations  used  in the  Permitted  Business  of the  Company  and  any
Restricted  Subsidiary  on the Closing Date or (ii) any material  portion of the
"property and  equipment"  (as such term is used in the  Company's  consolidated
financial  statements) of the Company or any Significant  Subsidiary used in the
licensed  service  areas of the Company and any  Restricted  Subsidiary  as they
exist on the Closing Date.

                  SECTION  1020.   Limitation  on  Investments  in  Unrestricted
Subsidiaries.

                  The  Company  shall not make,  and shall not permit any of its
Restricted  Subsidiaries to make, any  Investments in Unrestricted  Subsidiaries
if, at the time thereof,  the aggregate amount of such Investments together with
any other  Restricted  Payments  made after the  Closing  Date would  exceed the
amount of  Restricted  Payments  then  permitted to be made  pursuant to Section
1012. Any Investments in Unrestricted Subsidiaries permitted to be made pursuant
to this  covenant (i) shall be treated as the making of a Restricted  Payment in
calculating
<PAGE>
                                       90

the amount of Restricted  Payments made by the Company or a Subsidiary  and (ii)
may be made in cash or property  (if made in  property,  the Fair  Market  Value
thereof  as  determined  by  the  Board  of  Directors  of  the  Company  (whose
determination  shall be conclusive and evidenced by a Board Resolution) shall be
deemed to be the amount of such Investment for the purpose of clause (i) of this
Section 1020).

                  SECTION 1021.  Limitation on Sale-Leaseback Transactions.

                  The  Company  shall  not,  and  shall  not  permit  any of its
Restricted  Subsidiaries  to,  enter into any  Sale-Leaseback  Transaction  with
respect to any property of the Company or any of its Restricted Subsidiaries.

                  Notwithstanding  the  foregoing,  the  Company  may enter into
Sale-Leaseback Transactions;  provided, however, that (a) the Attributable Value
of such  Sale-Leaseback  Transaction  shall be deemed to be  Indebtedness of the
Company  and (b)  after  giving  pro  forma  effect  to any such  Sale-Leaseback
Transaction  and the  foregoing  clause (a), the Company  would be able to incur
$1.00 of additional Indebtedness (other than Permitted Indebtedness) pursuant to
paragraph (a) of Section 1011.

                  SECTION 1022.  Waiver of Certain Covenants.

                  The Company may omit in any particular instance to comply with
any term,  provision  or  condition  set forth in Section 803 or  Sections  1007
through 1021,  inclusive,  if before or after the time for such  compliance  the
Holders of at least a majority in aggregate  principal amount of the Outstanding
Notes, by Act of such Holders,  waive such compliance in such instance with such
term, provision or condition,  but no such waiver shall extend to or affect such
term,  provision or condition  except to the extent so  expressly  waived,  and,
until such waiver shall become effective, the obligations of the Company and the
duties of the Trustee in respect of any such term,  provision or condition shall
remain in full force and effect.

                                 ARTICLE ELEVEN

                               REDEMPTION OF NOTES

                  SECTION 1101.  Right of Redemption.

                  (a) The Notes may be redeemed, at the election of the Company,
in whole or in part, at any time or from time to time, on or after May 15, 2003,
subject to the conditions and at the Redemption  Prices specified in the form of
Note,  together with accrued and unpaid interest and Liquidated Damages, if any,
thereon to the Redemption Date.
<PAGE>
                                       91

                  (b) Notwithstanding the foregoing,  prior to May 15, 2001, the
Company may redeem up to 35% of the originally issued aggregate principal amount
of the Notes on one or more  occasions with the Net Cash Proceeds of one or more
Public  Equity  Offerings at a redemption  price equal to 112% of the  aggregate
principal  amount  thereof,  plus  accrued  and  unpaid  interest,  if any,  and
Liquidated  Damages,  if any,  thereon to the  Redemption  Date;  provided that,
immediately  after  giving  effect  to such  redemption,  at least  65.0% of the
originally issued aggregate  principal amount of the Notes remains  Outstanding;
and provided  further that notice of such  redemptions  shall be given within 60
days of the date of closing of any such Public Equity Offering.

                  SECTION 1102.  Applicability of Article.

                  Redemption  of  Notes  at  the  election  of  the  Company  or
otherwise, as permitted or required by any provision of this Indenture, shall be
made in accordance with such provision and this Article.

                  SECTION 1103.  Election to Redeem; Notice to Trustee.

                  The  election of the  Company to redeem any Notes  pursuant to
Section 1101 shall be evidenced by a Board Resolution. In case of any redemption
at the election of the Company, the Company shall, at least 60 days prior to the
Redemption  Date  fixed  by the  Company  (unless  a  shorter  notice  shall  be
satisfactory  to the Trustee),  notify the Trustee in writing of such Redemption
Date and of the  Redemption  Price  and of the  principal  amount of Notes to be
redeemed  and shall  deliver to the Trustee  such  documentation  and records as
shall enable the Trustee to select the Notes to be redeemed  pursuant to Section
1104.

                  SECTION 1104.  Selection by Trustee of Notes to Be Redeemed.

                  If less than all the Notes are to be redeemed,  the particular
Notes to be  redeemed  shall be  selected  not  more  than 60 days  prior to the
Redemption Date by the Trustee, from the Outstanding Notes not previously called
for redemption,  in compliance with the  requirements of the principal  national
securities exchange,  if any, on which the Notes are listed or, if the Notes are
not listed on a national securities exchange,  on a pro rata basis, by lot or by
such  other  method as the  Trustee in its sole  discretion  shall deem fair and
appropriate  and which may provide for the selection for  redemption of portions
of the principal of Notes; provided,  however, that no Note of $1,000 or less in
principal amount at maturity shall be redeemed in part.

                  The Trustee  shall  promptly  notify the Company in writing of
the Notes  selected for  redemption  and, in the case of any Notes  selected for
partial redemption, the principal amount thereof to be redeemed.
<PAGE>
                                       92

                  For  all  purposes  of  this  Indenture,  unless  the  context
otherwise requires, all provisions relating to redemption of Notes shall relate,
in the case of any Note  redeemed or to be redeemed only in part, to the portion
of the principal amount of such Note which has been or is to be redeemed.

                  SECTION 1105.  Notice of Redemption.

                  Notice of redemption shall be given in the manner provided for
in Section  106 not less than 30 nor more than 60 days  prior to the  Redemption
Date, to each Holder of Notes to be redeemed.

                  All notices of redemption shall state:

                  (1)     the Redemption Date;

                  (2) the Redemption Price and the amount of accrued interest to
         the Redemption Date payable as provided in Section 1107, if any;

                  (3) if less than all Outstanding Notes are to be redeemed, the
         identification (and, in the case of a partial redemption, the principal
         amounts) of the particular Notes to be redeemed;

                  (4) in case  any  Note is to be  redeemed  in part  only,  the
         notice  which  relates to such Note  shall  state that on and after the
         Redemption Date, upon surrender of such Note, the Holder shall receive,
         without charge, a new Note or Notes of authorized denominations for the
         principal amount thereof remaining unredeemed;

                  (5) that on the  Redemption  Date the  Redemption  Price  (and
         accrued interest, if any, to the Redemption Date payable as provided in
         Section  1107) will become due and payable upon each such Note,  or the
         portion thereof,  to be redeemed,  and that interest thereon will cease
         to accrue on and after said date; and

                  (6) the place or places where such Notes are to be surrendered
         for payment of the Redemption Price and accrued interest, if any.

                  Notice of  redemption  of Notes to be redeemed at the election
of the  Company  shall be given by the  Company  or,  at the  Company's  written
request, by the Trustee in the name and at the expense of the Company.

                  SECTION 1106.  Deposit of Redemption Price.

<PAGE>
                                       93

                  Prior to any  Redemption  Date, the Company shall deposit with
the  Trustee  or with a Paying  Agent (or,  if the  Company is acting as its own
Paying Agent, segregate and hold in trust as provided in Section 1003) an amount
of money sufficient to pay the Redemption Price of, and Liquidated  Damages,  if
any,  and  accrued  interest  on, all the Notes which are to be redeemed on that
date.

                  SECTION 1107.  Notes Payable on Redemption Date.

                  Notice of redemption having been given as aforesaid, the Notes
so to be redeemed shall, on the Redemption  Date,  become due and payable at the
Redemption Price therein specified (together with Liquidated Damages and accrued
interest,  if any, to the Redemption Date), and from and after such date (unless
the Company  shall  default in the payment of the  Redemption  Price and accrued
interest)  such Notes shall cease to bear  interest.  Upon surrender of any such
Note for redemption in accordance  with said notice,  such Note shall be paid by
the  Company at the  Redemption  Price,  together  with  Liquidated  Damages and
accrued  interest,  if any, to the  Redemption  Date;  provided,  however,  that
installments  of interest whose Stated Maturity is on or prior to the Redemption
Date shall be payable to the Holders of such Notes,  or one or more  Predecessor
Notes,  registered  as such at the close of  business  on the  relevant  Regular
Record Dates according to their terms and the provisions of Section 307.

                  If any Note  called for  redemption  shall not be so paid upon
surrender  thereof for  redemption,  the  principal  (and  premium,  if any) and
accrued  interest  shall,  until paid, bear interest from the Redemption Date at
the rate borne by the Notes.

                  SECTION 1108.  Notes Redeemed in Part.

                  Any Note which is to be redeemed only in part (pursuant to the
provisions of this Article  Eleven) shall be surrendered at the office or agency
of the Company  maintained for such purpose  pursuant to Section 1002 (with,  if
the  Company  or the  Trustee  so  requires,  due  endorsement  by, or a written
instrument of transfer in form  satisfactory to the Company and the Trustee duly
executed by, the Holder  thereof or such Holder's  attorney  duly  authorized in
writing),  and the Company  shall  execute,  and the Trustee  shall upon Company
Order  authenticate  and  deliver  to the  Holder of such Note  without  service
charge, a new Note or Notes, of any authorized denomination as requested by such
Holder,  in  aggregate  principal  amount  equal  to and  in  exchange  for  the
unredeemed portion of the principal of the Note so surrendered.

                  SECTION 1201.  Security.

                  (a) On the Closing Date, the Company shall  purchase,  and, at
all times,  subject to the Pledge Agreement,  shall maintain Pledged  Securities
pledged to the Trustee as security for the benefit of the Holders in such amount
as will be  sufficient  upon  receipt of  scheduled  interest  and/or  principal
payments of such Pledged Securities,  in the opinion of a nationally  recognized
firm of independent public accountants  selected by the Company,  to provide for
payment  in  full  of the  first  six  scheduled  interest  payments  due on the
outstanding Notes. The Pledged Securities shall be pledged by the Company to the
Trustee  for the  benefit of the Holders and shall be held by the Trustee in the
Pledge Account pending disposition pursuant to the Pledge Agreement.

                  (b) Each Holder,  by its  acceptance  of a Note,  consents and
agrees to the terms of the Pledge Agreement (including,  without limitation, the
provisions  providing for foreclosure and release of the Pledged  Securities) as
the same may be in effect or may be amended from time to time in accordance with
its terms,  and  authorizes  and  directs  the  Trustee to enter into the Pledge
Agreement and to perform its respective  obligations and exercise its respective
rights thereunder in accordance  therewith.  The Company shall do or cause to be
done all such  acts and  things  as may be  necessary  or  proper,  or as may be
required by the provisions of the Pledge Agreement, to assure and confirm to the
Trustee the security interest in the Pledged Securities  contemplated hereby, by
the Pledge Agreement or any part thereof,  as from time to time constituted,  so
as to render the same  available for the security and benefit of this  Indenture
and of the Notes  secured  hereby,  according to the intent and purposes  herein
expressed.  The  Company  shall take,  or shall  cause to be taken,  any and all
actions reasonably required (and any action reasonably requested by the Trustee)
to cause the  Pledge  Agreement  to create and  maintain,  as  security  for the
obligations  of the  Company  under  this  Indenture  and the  Notes,  valid and
enforceable first priority liens in and on all the Pledged Securities,  in favor
of the Trustee, superior to and prior to the rights of third Persons and subject
to no other Liens.

                  (c) The  release of any  Pledged  Securities  pursuant  to the
Pledge  Agreement will not be deemed to impair the security under this Indenture
in  contravention  of the  provisions  hereof if and to the extent  the  Pledged
Securities are released pursuant to this Indenture and the Pledge Agreement.  To
the extent  applicable,  the Company shall cause TIA Section 314(d)  relating to
the release of property or securities from the Lien and security interest of the
Pledge  Agreement  (other than  pursuant to Sections  7(e) and 7(g) thereof) and
relating to the  substitution  therefor  of any  property  or  securities  to be
subjected  to the Lien and  security  interest  of the  Pledge  Agreement  to be
complied with. Any certificate or opinion  required by TIA Section 314(d) may be
made by an officer of the  Company,  except in cases  where TIA  Section  314(d)
requires  that such  certificate  or opinion be made by an  independent  Person,
which  Person  shall be an  independent  engineer,  appraiser  or  other  expert
selected by the Company.

                  (d) The  Trustee,  in its  sole  discretion  and  without  the
consent of the  Holders,  may, and at the request of the Holders of at least 25%
in aggregate  principal amount of Notes then outstanding shall, on behalf of the
Holders,  take all actions it deems  necessary  or  appropriate  in order to (i)
enforce any of the terms of the Pledge  Agreement  and (ii)  collect and receive
any and all  amounts  payable  in  respect  of the  obligations  of the  Company
thereunder.  The Trustee  shall have the power to institute and to maintain such
suits and  proceedings as the Trustee in its sole  discretion may deem expedient
to preserve or protect its  interests  and the  interests  of the Holders in the
Pledged  Securities  (including  the power to institute  and  maintain  suits or
proceedings to restrain the enforcement of or compliance with any legislative or
other  governmental  enactment,  rule or order that may be  unconstitutional  or
otherwise  invalid if the  enforcement  of, or compliance  with, such enactment,
rule or order would impair the security interest  hereunder or be prejudicial to
the interests of the Holders or of the Trustee).

                                ARTICLE THIRTEEN

                       DEFEASANCE AND COVENANT DEFEASANCE

                  SECTION  1301.   Company's  Option  to  Effect  Defeasance  or
Covenant Defeasance.

                  The  Company  may, at its option by Board  Resolution,  at any
time,  with respect to the Notes,  elect to have either  Section 1302 or Section
1303 be applied to all Outstanding Notes upon compliance with the conditions set
forth below in this Article Thirteen.

                  SECTION 1302.  Defeasance and Discharge.

                  Upon the Company's  exercise  under Section 1301 of the option
applicable  to this  Section  1302,  the  Company  shall be  deemed to have been
discharged  from its obligations  with respect to all  Outstanding  Notes on the
date the  conditions  set  forth in  Section  1304 are  satisfied  (hereinafter,
"defeasance"). For this purpose, such defeasance means that the Company shall be
deemed to have paid and  discharged the entire  indebtedness  represented by the
Outstanding Notes, which shall thereafter be deemed to be "Outstanding" only for
the purposes of Section 1305 and the other Sections of this  Indenture  referred
to in (A) and (B) below, and to have satisfied all its other  obligations  under
such  Notes and this  Indenture  insofar as such  Notes are  concerned  (and the
Trustee,  at the  expense  of the  Company,  shall  execute  proper  instruments
acknowledging  the same),  except for the  following  which shall  survive until
otherwise  terminated  or  discharged  hereunder:  (A) the  rights of Holders of
Outstanding Notes to receive payments (solely from monies deposited in trust) in
respect of the principal of, premium,  if any,  accrued  interest and Liquidated
Damages,  if any, on such Notes when such  payments are due,  (B) the  Company's
obligations with respect to such Notes under Sections 304, 305, 306, 1002

<PAGE>
                                       96

and 1003, (C) the rights,  powers,  trusts, duties and immunities of the Trustee
hereunder and (D) this Article Thirteen. Subject to compliance with this Article
Thirteen,   the  Company  may  exercise  its  option  under  this  Section  1302
notwithstanding the prior exercise of its option under Section 1303 with respect
to the Notes.

                  SECTION 1303.  Covenant Defeasance.

                  Upon the Company's  exercise  under Section 1301 of the option
applicable  to this  Section  1303,  the  Company  shall  be  released  from its
obligations  under any covenant  contained in Section 801(3) and (4) and Section
803 and in Sections 1007 through 1022 with respect to the  Outstanding  Notes on
and after the date the  conditions  set forth below are satisfied  (hereinafter,
"covenant  defeasance"),  and the Notes  shall  thereafter  be deemed  not to be
"Outstanding" for the purposes of any direction,  waiver, consent or declaration
or Act of Holders (and the  consequences of any thereof) in connection with such
covenants,  but shall continue to be deemed "Outstanding" for all other purposes
hereunder.  For this purpose,  such covenant defeasance means that, with respect
to the Outstanding  Notes, the Company may omit to comply with and shall have no
liability in respect of any term,  condition or limitation set forth in any such
covenant,  whether directly or indirectly,  by reason of any reference elsewhere
herein to any such  covenant or by reason of any  reference in any such covenant
to any other  provision  herein or in any other  document  and such  omission to
comply  shall not  constitute  a Default  or an Event of Default  under  Section
501(6), but, except as specified above, the remainder of this Indenture and such
Notes shall be unaffected thereby.

                  SECTION 1304. Conditions to Defeasance or Covenant Defeasance.

                  The following shall be the conditions to application of either
Section 1302 or Section 1303 to the Outstanding Notes:

                  (1) The Company shall  irrevocably have deposited or caused to
         be  deposited  with the  Trustee  (or another  trustee  satisfying  the
         requirements  of  Section  607 who  shall  agree  to  comply  with  the
         provisions of this Article Thirteen applicable to it) as trust funds in
         trust for the purpose of making the  following  payments,  specifically
         pledged as security  for, and  dedicated  solely to, the benefit of the
         Holders of such  Notes,  (A) cash in United  States  dollars,  (B) U.S.
         Government Obligations or (C) a combination thereof, in such amounts as
         will be sufficient,  in the opinion of a nationally  recognized firm of
         independent  public  accountants  expressed in a written  certification
         thereof delivered to the Trustee, to pay and discharge, and which shall
         be applied by the  Trustee  (or other  qualifying  trustee)  to pay and
         discharge, the principal of (and premium, if any), accrued interest and
         Liquidated  Damages,  if any,  on the  Outstanding  Notes on the Stated
         Maturity (or  Redemption  Date, if  applicable)  of such principal (and
         premium,  if any) or installment of interest and Liquidated Damages, if
         any; provided that the Trustee shall
<PAGE>
                                       97

         have been irrevocably instructed to apply such money or the proceeds of
         such U.S.  Government  Obligations to said payments with respect to the
         Notes.  Before such a deposit,  the Company may give to the Trustee, in
         accordance with Section 1103 hereof, a notice of its election to redeem
         all of the  Outstanding  Notes  at a  future  date in  accordance  with
         Article  Eleven  hereof,  which  notice  shall  be  irrevocable.   Such
         irrevocable  redemption  notice,  if  given,  shall be given  effect in
         applying the foregoing. For this purpose, "U.S. Government Obligations"
         means  securities that are (x) direct  obligations of the United States
         for the timely payment of which its full faith and credit is pledged or
         (y)  obligations of a Person  controlled or supervised by and acting as
         an agency or instrumentality of the United States the timely payment of
         which  is  unconditionally  guaranteed  as  a  full  faith  and  credit
         obligation  by the  United  States,  which,  in  either  case,  are not
         callable or redeemable at the option of the issuer  thereof,  and shall
         also  include a  depository  receipt  issued by a "bank" (as defined in
         Section  3(a)(2) of the  Securities  Act), as custodian with respect to
         any such U.S. Government  Obligation or a specific payment of principal
         of or  interest  on any such U.S.  Government  Obligation  held by such
         custodian  for the  account of the holder of such  depository  receipt,
         provided  that  (except  as  required  by law)  such  custodian  is not
         authorized to make any deduction  from the amount payable to the holder
         of such depository receipt from any amount received by the custodian in
         respect of the U.S.  Government  Obligation or the specific  payment of
         principal of or interest on the U.S. Government Obligation evidenced by
         such depository receipt.

                     (2) No  Default  or Event of  Default  with  respect to the
         Notes shall have occurred and be continuing on the date of such deposit
         or,  insofar as an event of bankruptcy  under  paragraph (9) or (10) of
         Section 501 hereof is  concerned,  at any time during the period ending
         on the 123rd day after the date of such deposit.

                     (3)  [Reserved]

                     (4) Such defeasance or covenant defeasance shall not result
         in a breach or violation of, or constitute a default under any material
         agreement  or  instrument  (other  than  this  Indenture)  to which the
         Company is a party or by which it is bound.

                     (5) In the case of an  election  under  Section  1302,  the
         Company  shall  have  delivered  to the  Trustee  an Opinion of Counsel
         stating  that (x) the  Company  has  received  from,  or there has been
         published by, the Internal  Revenue Service a ruling,  or (y) since May
         21, 1998, there has been a change in the applicable  federal income tax
         law, in either case to the effect, and based thereon such opinion shall
         confirm,  that  Holders  will not  recognize  income,  gain or loss for
         federal income tax purposes as a result of such  defeasance and will be
         subject to federal income tax on the same amounts, in the same

<PAGE>
                                       98

         manner  and at the  same  times  as  would  have  been the case if such
         defeasance had not occurred.

                     (6) In the case of an  election  under  Section  1303,  the
         Company  shall have  delivered  to the Trustee an Opinion of Counsel to
         the effect that the Holders will not recognize income, gain or loss for
         federal income tax purposes as a result of such covenant defeasance and
         will be subject to federal income tax on the same amounts,  in the same
         manner  and at the  same  times  as  would  have  been the case if such
         covenant defeasance had not occurred.

                     (7) The  Company  shall have  delivered  to the  Trustee an
         Officer's  Certificate and an Opinion of Counsel, each stating that all
         conditions  precedent  provided for  relating to either the  defeasance
         under  Section 1302 or the covenant  defeasance  under Section 1303 (as
         the case may be) have been complied with.

                  SECTION 1305. Deposited Money and U.S. Government  Obligations
to Be Held in Trust; Other Miscellaneous Provisions.

                  Subject to the  provisions  of the last  paragraph  of Section
1003, all money and U.S. Government Obligations (including the proceeds thereof)
deposited  with the  Trustee  (or other  qualifying  trustee,  collectively  for
purposes of this  Section  1305,  the  "Trustee")  pursuant  to Section  1304 in
respect  of the  Outstanding  Notes  shall be held in trust and  applied  by the
Trustee, in accordance with the provisions of such Notes and this Indenture,  to
the payment,  either directly or through any Paying Agent (including the Company
acting as its own Paying Agent) as the Trustee may determine,  to the Holders of
such  Notes of all sums due and to become due  thereon  in respect of  principal
(and premium,  if any) and interest,  but such money need not be segregated from
other funds except to the extent required by law.

                  The Company shall pay and  indemnify  the Trustee  against any
tax, fee or other charge  imposed on or assessed  against the U.S.  Governmental
Obligations  deposited  pursuant to Section 1304 or the  principal  and interest
received in respect  thereof  other than any such tax, fee or other charge which
by law is for the account of the Holders.

                  Anything   in   this   Article   Thirteen   to  the   contrary
notwithstanding,  the Trustee  shall  deliver or pay to the Company from time to
time upon Company Request any money or U.S. Government Obligations held by it as
provided in Section 1304 which,  in the opinion of a nationally  recognized firm
of independent public accountants  expressed in a written  certification thereof
delivered to the Trustee,  are in excess of the amount  thereof which would then
be required  to be  deposited  to effect an  equivalent  defeasance  or covenant
defeasance, as applicable, in accordance with this Article.

                  SECTION 1306.  Reinstatement.

                  If the  Trustee  or any  Paying  Agent is  unable to apply any
money in accordance  with Section 1305 by reason of any order or judgment of any
court or governmental authority enjoining,  restraining or otherwise prohibiting
such  application,  then the Company's  obligations under this Indenture and the
Notes shall be revived and reinstated as though no deposit had occurred pursuant
to Section  1302 or 1303,  as the case may be, until such time as the Trustee or
Paying  Agent is permitted  to apply all such money in  accordance  with Section
1305; provided,  however,  that if the Company makes any payment of principal of
(or premium,  if any) or interest on any Note following the reinstatement of its
obligations,  the Company  shall be  subrogated  to the rights of the Holders of
such Notes to receive  such payment from the money held by the Trustee or Paying
Agent.

                  This  Indenture  may be signed in any  number of  counterparts
each of which  so  executed  shall be  deemed  to be an  original,  but all such
counterparts shall together constitute but one and the same Indenture.

Indenture to be duly executed as of the day and year first above written.

                  STARTEC   GLOBAL   COMMUNICATIONS   CORPORATION,   a  Maryland
corporation  (herein  called the  "Company,"  which term  includes any successor
Person under the Indenture hereinafter referred to), for value received,  hereby
promises to pay to  __________________  or registered assigns, the principal sum
of ___ United  States  dollars on May 15,  2008,  at the office or agency of the
Company  referred to below, and to pay interest thereon on November 15, 1998 and
semi-annually  thereafter,  on November 15 and May 15 in each year, from May 21,
1998 or from the most recent  Interest  Payment Date to which  interest has been
paid or duly  provided  for, at the rate of 12% per annum,  until the  principal
hereof is paid or duly provided for, and (to the extent lawful) to pay on demand
interest on any overdue interest at the rate borne by the Notes from the date on
which such overdue interest becomes payable to the date payment of such interest
has been made or duly provided for. The interest so payable, and punctually paid
or duly  provided  for, on any Interest  Payment Date will,  as provided in such
Indenture,  be paid to the  Person  in  whose  name  this  Note  (or one or more
Predecessor  Notes) is registered at the close of business on the Regular Record
Date for such interest, which shall be the November 1 or May 1 (whether or not a
Business Day), as the case may be, next  preceding  such Interest  Payment Date.
Any such  interest not so punctually  paid or duly provided for shall  forthwith
cease  to be  payable  to the  Holder  on such  Regular  Record  Date,  and such
Defaulted  Interest,  and (to the  extent  lawful)  interest  on such  Defaulted
Interest at the rate borne by the Notes, may be paid to the Person in whose name
this  Note (or one or more  Predecessor  Notes)  is  registered  at the close of
business on a Special Record Date for the payment of such Defaulted  Interest to
be fixed by the Trustee,  notice  whereof shall be given to Holders of Notes not
less than 10 days prior to such Special  Record Date, or may be paid at any time
in any  other  lawful  manner  not  inconsistent  with the  requirements  of any
securities  exchange  on which the Notes may be listed,  and upon such notice as
may be required by such exchange, all as more fully provided in said Indenture.

                  The Holder of this Note is  entitled  to the  benefits  of the
Registration  Rights  Agreement,  dated as of May 21,  1998  (the  "Registration
Rights  Agreement"),  between  the  Company  and the  Initial  Purchasers  named
therein.  In the  event  that  either  (i) the  Company  fails to file  with the
Commission  any of the  Registration  Statements  required  by the  Registration
Rights Agreement on or before the date specified  therein for such filing,  (ii)
any of such Registration  Statements is not declared effective by the Commission
on or prior to the date
<PAGE>
                                       A-2

specified for such  effectiveness  in the  Registration  Rights  Agreement  (the
"Effectiveness  Target Date"), (iii) the Exchange Offer has not been consummated
within 30 days after the Effectiveness  Target Date with respect to the Exchange
Offer Registration  Statement or (iv) any Registration Statement required by the
Registration  Rights  Agreement is filed and declared  effective but  thereafter
ceases to be effective or fails to be usable for its  intended  purpose  without
being succeeded within five business days by a post-effective  amendment to such
Registration  Statement  that cures such failure and that is declared  effective
within such five business day period (each such event referred to in clauses (i)
through  (iv)  above,  a  "Registration  Default"),   additional  cash  interest
("Liquidated  Damages") shall accrue to each Holder of the Notes commencing upon
the occurrence of such Registration Default in an amount equal to .50% per annum
of the principal  amount of Notes held by such Holder.  The amount of Liquidated
Damages will increase by an additional .50% per annum of the principal amount of
Notes with respect to each subsequent  90-day period (or portion  thereof) until
all  Registration  Defaults have been cured,  up to a maximum rate of Liquidated

provisions of the  Indenture  and certain past defaults  under the Indenture and
their consequences.  Any such consent or waiver by or on behalf of the Holder of
this Note shall be  conclusive  and binding upon such Holder and upon all future
Holders of this Note and of any Note  issued upon the  registration  of transfer
hereof or in exchange herewith or in lieu hereof whether or not notation of such
consent or waiver is made upon this Note.

                  This   Certificate   relates  to  our  proposed   transfer  of
$__________ principal amount of Notes issued under the Indenture dated as of May
21, 1998 relating to the Notes. Terms are used in this Certificate as defined in
Regulation  S under the  Securities  Act of 1933,  as amended  (the  "Securities
Act"). We hereby certify as follows:

                  1. The  offer  of the  Notes  was not made to a person  in the
         United  States  (unless such person or the account held by it for which
         it is acting is excluded from the definition of "U.S.  person" pursuant
         to Rule 902(o) of  Regulation  S under the  circumstances  described in
         Rule  902(i)(3)  of  Regulation  S)  or  specifically  targeted  at  an
         identifiable group of U.S. citizens abroad.

                  2.  Either (a) at the time the buy order was  originated,  the
         buyer was outside the United  States or we and any person acting on our
         behalf reasonably believed that the buyer was outside the United States
         or (b) the transaction was executed in, on or through the facilities of
         a designated  offshore securities market, and neither we nor any person
         acting on our behalf knows that the transaction was pre-arranged with a
         buyer in the United States.

                  3. Neither we, any of our affiliates, nor any person acting on
         our or their  behalf,  has made any  directed  selling  efforts  in the
         United States.

                  4.  The  proposed  transfer  of Notes is not part of a plan or
         scheme to evade the registration requirements of the Securities Act.

                  5.  If  we  are a  dealer  or a  person  receiving  a  selling
         concession or other fee or  remuneration  in respect of the Notes,  and
         the  proposed  transfer  takes  place  before  the  completion  of  the
         Regulation S Global Note Exchange  Offer  referred to in the Indenture,
         or we are an officer or director of the  Company or a  distributor,  we
         certify that the proposed transfer is being made in accordance with the
         provisions of Rule 904(c) of Regulation S.

                  You and the Company are entitled to rely upon this Certificate
and are irrevocably  authorized to produce this  Certificate or a copy hereof to
any  interested  party in any  administrative  or legal  proceeding  or official

after the  Closing  Date,  but in no event  later than 90 days after the Closing

                                        5
<PAGE>
Statement  pursuant  to Rule  430A  under the  Securities  Act and (C) cause all
necessary  filings in connection with the registration and  qualification of the
Exchange Notes to be made under the Blue Sky laws of such  jurisdictions  as are
necessary to permit the  Consummation  of the Exchange  Offer,  and (iv) use its
reasonable  best efforts to cause the  Exchange  Offer to be  consummated  on or
prior to 30 days  after  the  date on  which  the  Exchange  Offer  Registration
Statement was declared effective by the Commission.  The Exchange Offer shall be
on the appropriate form of Registration Statement permitting registration of the
Exchange Notes to be offered in exchange for the Transfer Restricted  Securities
and to permit resales of Exchange Notes held by  Broker-Dealers  as contemplated
by Section 3(c) below.  The 90, 150 and 30-day periods  referred to in (i), (ii)
and (iii) of this  Section  3(a) shall not include any period  during  which the
Company is seeking a  "no-action"  letter or other  favorable  decision from the
Commission pursuant to Section 6(a)(i) below.

                           (b) The Company shall use its reasonable best efforts
to cause the Exchange Offer Registration  Statement to be effective continuously
and shall keep the Exchange Offer open for a period of not less than the minimum
period required under applicable federal and state securities laws to Consummate
the Exchange  Offer;  provided,  however,  that in no event shall such period be
less than 20 business days. The Company shall cause the Exchange Offer to comply
in all material respects with all applicable  federal and state securities laws.
No  securities  other than the Exchange  Notes shall be included in the Exchange
Offer Registration Statement.

                           (c)  The  Company  shall   indicate  in  a  "Plan  of
Distribution"  section  contained  in the  Prospectus  contained in the Exchange
Offer  Registration  Statement that any  Broker-Dealer  who holds Notes that are
Transfer  Restricted  Securities and that were acquired for its own account as a
result of  market-making  activities  or other  trading  activities  (other than
Transfer Restricted  Securities acquired directly from the Company) may exchange
such Notes pursuant to the Exchange Offer;  however,  such  Broker-Dealer may be
deemed  to be an  "underwriter"  within  the  meaning  of  Section  2(11) of the
Securities  Act  and  must,   therefore,   deliver  a  prospectus   meeting  the
requirements  of the  Securities  Act in  connection  with  any  resales  of the
Exchange  Notes  received by such  Broker-Dealer  in the Exchange  Offer,  which
prospectus  delivery  requirement  may be  satisfied  by the  delivery  by  such
Broker-Dealer  of the Prospectus  contained in the Exchange  Offer  Registration
Statement.  Such "Plan of  Distribution"  section  shall also  contain all other
information with respect to such resales by  Broker-Dealers  that the Commission
may require in order to permit such resales pursuant thereto,  but such "Plan of
Distribution"  shall not name any such  Broker-Dealer  or disclose the amount of
Exchange Notes held by any such  Broker-Dealer  except to the extent required by
the  Commission  as a result of a change in policy  announced  after the date of
this Agreement or as required by the Securities Act.

                  The Company shall use its reasonable  best efforts to keep the
Exchange Offer Registration Statement continuously  effective,  supplemented and
amended  as  required  by the  provisions  of  Section  6(c) below to the extent
necessary to ensure that it is available for resales of Exchange  Notes acquired
by Broker-Dealers for their own accounts as a result of market-making activities
or  other  trading  activities,   and  to  ensure  that  it  conforms  with  the
requirements of this Agreement,  the Securities Act and the policies,  rules and
regulations  of the  Commission as announced  from time to time, for a period of
180 days from the date on which the Exchange Offer is Consummated.

                  The  Company  shall  provide  sufficient  copies of the latest
version of such Prospectus to  Broker-Dealers  promptly upon request at any time
during such 180-day period in order to facilitate such resales.

                  4.       Shelf Registration.

                           (a) Shelf  Registration.  If (i) the  Company  is not
permitted to file an Exchange Offer Registration  Statement or to consummate the
Exchange  Offer because the Exchange Offer is not permitted by applicable law or
Commission  policy  (after the  procedures  set forth in Section 6(a) below have
been complied with), (ii) any Holder of Transfer Restricted Securities that is a
"qualified  institutional  buyer" (as defined in Rule 144A under the  Securities
Act) or an  institutional  "accredited  investor" (as defined in Rule 501(A)(l),
(2), (3) or (7) under the  Securities  Act) shall notify the Company at least 20
business  days prior to the  Consummation  of the  Exchange  Offer (A) that such
Holder is  prohibited  by  applicable  law or  Commission  policy or action from
participating  in the Exchange Offer, or (B) that such Holder may not resell the
Exchange  Notes  acquired  by it in the  Exchange  Offer to the  public  without
delivering a prospectus and that the Prospectus  contained in the Exchange Offer
Registration  Statement is not appropriate or available for such resales by such
Holder,  or (C) that such Holder is a  Broker-Dealer  and holds  Notes  acquired
directly from the Company or one of its "Affiliates" (as such term is defined in
the  Indenture),  (iii) the Exchange  Offer is not, for any reason,  consummated
within  180 days  after the  Closing  Date or (iv) the  Exchange  Offer has been
completed  and  in  the  opinion  of  counsel  for  the  Initial  Purchasers,  a
Registration  Statement must be filed and a prospectus  must be delivered by the
Initial  Purchasers  in  connection  with  any  offering  or  sale  of  Transfer
Restricted Securities, the Company will use its reasonable best efforts to:

                                   (x)  cause to be  filed a shelf  registration
         statement  pursuant to Rule 415 under the Securities  Act, which may be
         an amendment to the Exchange  Offer  Registration  Statement (in either
         event,  the  "Shelf  Registration  Statement"),  within  60 days of the
         earliest to occur of (i) through (iv) above; and

                                   (y) cause such Shelf  Registration  Statement
         to be declared effective by the Commission on or prior to the 150th day
         after such obligation arises (the "Shelf Filing Deadline").

The  Company  shall  use  its  reasonable   best  efforts  to  keep  such  Shelf
Registration  Statement  continuously  effective,  supplemented  and  amended as
required  by the  provisions  of  Sections  6(b) and (c)  hereof  to the  extent
necessary  to ensure that it is  available  for  resales of Transfer  Restricted
Securities  by the Holders of  Transfer  Restricted  Securities  entitled to the
benefit  of  this  Section  4(a),  and to  ensure  that  it  conforms  with  the
requirements of this Agreement,  the Securities Act and the policies,  rules and
regulations  of the  Commission  as  announced  from time to time,  for a period
ending on the second anniversary of the Closing Date.

                           (b)  Provision by Holders of Certain  Information  in
Connection  with  the  Shelf  Registration  Statement.  No  Holder  of  Transfer
Restricted  Securities may include any of its Transfer Restricted  Securities in
any Shelf  Registration  Statement  pursuant to this Agreement  unless and until
such Holder  furnishes to the Company in writing,  within 20 Business Days after
receipt of a request  therefor,  such  information as the Company may reasonably
request, or which is required under the Securities Act,

                                        7

for use in  connection  with any Shelf  Registration  Statement or Prospectus or
preliminary  Prospectus  included  therein.  No  Holder of  Transfer  Restricted
Securities shall be entitled to Liquidated  Damages pursuant to Section 5 hereof
unless and until such Holder shall have provided all such  reasonably  requested
information.  Each Holder as to which any Shelf Registration  Statement is being
effected agrees to furnish  promptly to the Company all information  required to
be  disclosed  in order  to make the  information  previously  furnished  to the
Company by such Holder not materially misleading.

                  5.       Liquidated Damages.

                           (a) If  (i)  the  Company  fails  to  file  with  the
Commission any of the Registration  Statements  required by this Agreement on or
before the date  specified for such filing in this  Agreement,  (ii) any of such
Registration  Statements is not declared effective by the Commission on or prior
to  the  date   specified  for  such   effectiveness   in  this  Agreement  (the
"Effectiveness  Target Date"), (iii) the Exchange Offer has not been Consummated
within 30 days after the Effectiveness  Target Date with respect to the Exchange
Offer Registration Statement or (iv) any Registration Statement required by this
Agreement  is filed and  declared  effective  but shall  thereafter  cease to be
effective or fails to be usable for its intended purpose without being succeeded
within five business  days by a  post-effective  amendment to such  Registration
Statement  that  cures  such  failure  and that is itself  immediately  declared
effective  (each such event  referred to in clauses (i)  through  (iv) above,  a
"Registration  Default"),  additional cash interest ("Liquidated Damages") shall
accrue to each  Holder  of the  Notes  commencing  upon the  occurrence  of such
Registration  Default  in an  amount  equal to .50% per  annum of the  principal
amount of Notes held by such  Holder.  The  amount of  Liquidated  Damages  will
increase by an additional  .50% per annum of the principal  amount of Notes with
respect  to each  subsequent  90-day  period  (or  portion  thereof)  until  all
Registration  Defaults  have  been  cured,  up to a maximum  rate of  Liquidated
Damages  of 1.50%  per annum of the  principal  amount  of  Notes.  All  accrued
Liquidated  Damages will be paid to Holders by the Company in the same manner as
interest  is  paid  pursuant  to  the  Indenture.  Following  the  cure  of  all
Registration Defaults relating to any particular Transfer Restricted Securities,
the accrual of  Liquidated  Damages  with  respect to such  Transfer  Restricted
Securities will cease.

                  All  obligations  of the  Company  set forth in the  preceding
paragraph  that have  accrued and are  outstanding  with respect to any Transfer
Restricted Security at the time such security ceases to be a Transfer Restricted
Security shall survive until such time as all such  obligations  with respect to
such Transfer Restricted Security shall have been satisfied in full.

                           (b) The Company  shall notify the Trustee  within one
business  day after each and every  date on which an event  occurs in respect of
which Liquidated  Damages are required to be paid (an "Event Date").  Liquidated
Damages  shall be paid by  depositing  Liquidated  Damages with the Trustee,  in
trust,  for the benefit of the Holders of the Notes, on or before the applicable
Interest Payment Date (whether or not any payment other than Liquidated  Damages
is payable on such Notes), in immediately  available funds in sums sufficient to
pay the  Liquidated  Damages then due to such  Holders.  Each  obligation to pay
Liquidated  Damages  shall be deemed to accrue from the  applicable  date of the
occurrence of the Registration Default

                  6.       Registration Procedures.

                           (a)  Exchange  Offer   Registration   Statement.   In
connection  with the Exchange  Offer,  the Company  shall comply with all of the
provisions  of Section  6(c) below,  shall use its  reasonable  best  efforts to
effect such Exchange Offer to permit the sale of Transfer Restricted  Securities
being sold in  accordance  with the intended  method or methods of  distribution
thereof,  and shall  comply  with all of the  following  provisions,  other than
paragraph (ii) of this Section 6(a),  which condition shall be performed only by
the Holders:

                                   (i) If, in the reasonable  opinion of counsel
         to the Company, there is a question as to whether the Exchange Offer is
         permitted by applicable law or Commission policy or action, the Company
         hereby agrees to seek a "no-action  letter" or other favorable decision
         from the  Commission  allowing  the Company to  Consummate  an Exchange
         Offer for such Notes.  The Company hereby agrees to pursue the issuance
         of such a letter or  decision to the  Commission  staff level but shall
         not be required to take  commercially  unreasonable  action to effect a
         change of Commission policy. The Company hereby agrees, however, to (A)
         participate in telephonic conferences with the Commission,  (B) deliver
         to the Commission staff an analysis  prepared by counsel to the Company
         setting  forth the legal  bases,  if any,  upon which such  counsel has
         concluded  that such an  Exchange  Offer  should be  permitted  and (C)
         diligently  pursue a resolution  (which need not be  favorable)  by the
         Commission staff of such submission.

                                   (ii) As a condition to its  participation  in
         the Exchange Offer pursuant to the terms of this Agreement, each Holder
         of Transfer  Restricted  Securities shall furnish,  upon the request of
         the   Company,   prior  to  the   Consummation   thereof,   a   written
         representation  to the Company (which may be contained in the letter of
         transmittal  contemplated by the Exchange Offer Registration Statement)
         to the effect that (A) such Holder is not an "Affiliate" of the Company
         (as  "Affiliate" is defined in the  Indenture),  (B) such Holder is not
         engaged  in,  does not intend to engage in, and has no  arrangement  or
         understanding  with any Person to participate in, a distribution of the
         Exchange  Notes to be issued in the Exchange  Offer and (C) such Holder
         is  acquiring  the Exchange  Notes in its ordinary  course of business.
         Each Holder hereby  acknowledges and agrees that any  Broker-Dealer and
         any  such  Holder  using  the  Exchange   Offer  to  participate  in  a
         distribution  of the  Exchange  Notes (1) could not,  under  Commission
         policy or action  as in effect on the date of this  Agreement,  rely on
         the position of the  Commission  enunciated in Morgan  Stanley and Co.,
         Inc.  (available June 5, 1991) and Exxon Capital  Holdings  Corporation
         (available May 13, 1988), as interpreted in the Commission's  letter to
         Shearman & Sterling dated July 2, 1993, and similar "no-action letters"
         (including  Brown & Wood LLP  (available  February  7,  1997),  and any
         "no-action letter" obtained pursuant to clause (i) above), and (2) must
         comply with the  registration and prospectus  delivery  requirements of
         the Securities  Act in connection  with a resale  transaction  and that
         such  a  resale   transaction   should  be  covered  by  an   effective
         registration   statement   containing  the  selling   security   holder
         information required by Items 507 or 508, as applicable,  of Regulation
         S-K if the  resales are of  Exchange  Notes  obtained by such Holder in
         exchange for  Transfer  Restricted  Securities  acquired by such Holder
         directly from the Company.

                                   (iii)  Prior  to  the  effectiveness  of  the
         Exchange  Offer  Registration  Statement,  the Company  shall provide a
         supplemental  letter to the  Commission (A) stating that the Company is
         registering  the  Exchange  Offer in  reliance  on the  position of the
         Commission enunciated in Exxon Capital Holdings Corporation  (available
         May 13, 1988), Morgan Stanley

                                        9
<PAGE>
         and Co., Inc.  (available  June 5, 1991),  Brown & Wood LLP  (available
         February 7, 1997) and, if applicable,  any "no-action  letter" obtained
         pursuant to clause (i) above and (B)  including a  representation  that
         the Company has not entered into any arrangement or understanding  with
         any Person to  distribute  the  Exchange  Notes to be  received  in the
         Exchange Offer and that, to the best of the Company's  information  and
         belief,  each Holder  participating  in the Exchange Offer is acquiring
         the  Exchange  Notes in its  ordinary  course  of  business  and has no
         arrangement  or  understanding  with any Person to  participate  in the
         distribution of the Exchange Notes received in the Exchange Offer.

                           (b) Shelf Registration  Statement. In connection with
the  Shelf  Registration  Statement,  the  Company  shall  comply  with  all the
provisions  of Section 6(c) below and shall use its  reasonable  best efforts to
effect  such  registration  to  permit  the  sale  of  the  Transfer  Restricted
Securities  being  sold in  accordance  with the  intended  method or methods of
distribution  thereof,  and pursuant thereto, the Company will, as expeditiously
as possible,  prepare and file with the Commission a  Registration  Statement on
any appropriate form which is available for the sale of the Transfer  Restricted
Securities in  accordance  with the intended  method or methods of  distribution
thereof.

                           (c)  General  Provisions.   In  connection  with  any
Registration  Statement and any Prospectus  required by this Agreement to permit
the  sale or  resale  of  Transfer  Restricted  Securities  (including,  without
limitation,  any Registration  Statement and the related Prospectus  required to
permit resales of Transfer Restricted Securities by Broker-Dealers), the Company
shall:

                                   (i) use its  reasonable  best efforts to keep
         such  Registration  Statement  continuously  effective  and provide all
         requisite financial statements for the period specified in Section 3 or
         4 of this  Agreement,  as applicable;  upon the occurrence of any event
         that would  cause any such  Registration  Statement  or the  Prospectus
         contained therein (A) to contain a material misstatement or omission or
         (B) not to be  effective  and usable for resale of Transfer  Restricted
         Securities  during the period  required by Section 4 of this Agreement,
         the  Company  shall file  promptly  an  appropriate  amendment  to such
         Registration  Statement, in the case of clause (A), correcting any such
         misstatement or omission, and, in the case of either clause (A) or (B),
         use its reasonable  best efforts to cause such amendment to be declared
         effective and such Registration Statement and the related Prospectus to
         become  usable for their  intended  purpose(s)  as soon as  practicable
         thereafter;

                                   (ii)  prepare  and file  with the  Commission
         such  amendments  and  post-effective  amendments  to the  Registration
         Statement  as may be  necessary  to  keep  the  Registration  Statement
         effective for the applicable period set forth in Section 3 or 4 hereof,
         as  applicable,  or such  shorter  period  as will  terminate  when all
         Transfer Restricted  Securities covered by such Registration  Statement
         have been sold; cause the Prospectus to be supplemented by any required
         Prospectus supplement, and as so supplemented,  to be filed pursuant to
         Rule 424  under  the  Securities  Act,  and to  comply  fully  with the
         applicable provisions of Rules 424 and 430A under the Securities Act in
         a timely  manner;  and comply with the provisions of the Securities Act
         with  respect  to the  disposition  of all  securities  covered by such
         Registration  Statement during the applicable period in accordance with
         the intended  method or methods of  distribution by the sellers thereof
         set  forth  in  such  Registration   Statement  or  supplement  to  the
         Prospectus;

                                   (iii)  in the  case of a  Shelf  Registration
         Statement,  advise the  underwriter(s),  if any,  and  selling  Holders
         promptly and, if requested by such  Persons,  to confirm such advice in
         writing,  (A) when  the  Prospectus  or any  Prospectus  supplement  or
         post-effective  amendment  has been  filed,  and,  with  respect to any
         Registration  Statement or any post-effective  amendment thereto,  when
         the  same  has  been  declared  effective,  (B) of any  request  by the
         Commission for amendments to the  Registration  Statement or amendments
         or supplements to the Prospectus or for additional information relating
         thereto,  (C) of the  issuance  by the  Commission  of any  stop  order
         suspending the  effectiveness of the  Registration  Statement under the
         Securities Act or of the suspension by any state securities  commission
         of the qualification of the Transfer Restricted Securities for offering
         or sale in any  jurisdiction,  or the  initiation of any proceeding for
         any of the foregoing purposes,  (D) of the existence of any fact or the
         happening of any event that makes any statement of a material fact made
         in  the  Registration  Statement,  the  Prospectus,  any  amendment  or
         supplement thereto,  or any document  incorporated by reference therein
         untrue,  or that  requires the making of any additions to or changes in
         the  Registration  Statement  or the  Prospectus  in  order to make the
         statements  therein not  misleading.  If, at any time,  the  Commission
         shall  issue  any  stop  order  suspending  the  effectiveness  of  the
         Registration  Statement,  or any state  securities  commission or other
         regulatory  authority shall issue an order suspending the qualification
         or exemption from qualification of the Transfer  Restricted  Securities
         under state  securities  or Blue Sky laws,  the  Company  shall use its
         reasonable  best  efforts to obtain the  withdrawal  or lifting of such
         order at the earliest possible time;

                                   (iv)  in the  case  of a  Shelf  Registration
         Statement,  furnish to each of the  selling or  exchanging  Holders and
         each of the underwriter(s),  if any, before filing with the Commission,
         copies of any Registration Statement or any Prospectus included therein
         or any amendments or supplements to any such Registration  Statement or
         Prospectus (including all documents incorporated by reference after the
         initial filing of such Registration Statement), which documents will be
         subject to the review of such Holders and underwriter(s), if any, for a
         period of at least three  business  days, and the Company will not file
         any such  Registration  Statement  or  Prospectus  or any  amendment or
         supplement to any such Registration  Statement or Prospectus (including
         all such documents  incorporated by reference) to which selling Holders
         of a majority in Liquidation Amount of Transfer  Restricted  Securities
         covered by such Registration  Statement or the underwriter(s),  if any,
         shall  reasonably  object within three  business days after the receipt
         thereof.  A selling Holder or  underwriter,  if any, shall be deemed to
         have reasonably objected to such filing if such Registration Statement,
         amendment,  Prospectus or supplement,  as applicable, as proposed to be
         filed, contains a material misstatement or omission;

                                   (v)  subject to a three  business  day review
         and objection period as provided in Section 6(a)(iv) of this Agreement,
         in the case of a Shelf  Registration  Statement,  promptly prior to the
         filing of any document that is to be  incorporated  by reference into a
         Registration  Statement or Prospectus,  provide copies of such document
         to the selling  Holders  and to the  underwriter(s),  if any,  make the
         Company's representatives available for discussion of such document and
         other customary due diligence matters,  and include such information in
         such document  prior to the filing  thereof as such selling  Holders or
         underwriter(s), if any, reasonably may request;

                                   (vi)  in the  case  of a  Shelf  Registration
         Statement,  make  available at reasonable  times for  inspection by the
         selling  Holders,  any  underwriter  participating  in any  disposition
         pursuant to such Registration Statement, and any attorney or accountant
         retained  by such  selling  Holders or any of the  underwriter(s),  all
         financial  and  other  records,   pertinent   corporate  documents  and
         properties of the Company and cause the Company's  officers,  directors
         and  employees to supply all  information  reasonably  requested by any
         such Holder,  underwriter,  attorney or accountant  in connection  with
         such Registration  Statement subsequent to the filing thereof and prior
         to its effectiveness;

                                   (vii)  in the  case of a  Shelf  Registration
         Statement,  if requested by any selling Holders or the  underwriter(s),
         if  any,  promptly   incorporate  in  any  Registration   Statement  or
         Prospectus,  pursuant to a supplement  or  post-effective  amendment if
         necessary, such information as such selling Holders and underwriter(s),
         if any, may  reasonably  request to have included  therein,  including,
         without limitation,  information relating to the "Plan of Distribution"
         of the Transfer Restricted Securities,  information with respect to the
         principal  amount of Transfer  Restricted  Securities  being sold,  the
         purchase  price being paid therefor and any other terms of the offering
         of the Transfer Restricted Securities to be sold in such offering;  and
         make  all   required   filings  of  such   Prospectus   supplement   or
         post-effective  amendment as soon as  practicable  after the Company is
         notified  of  the  matters  to  be   incorporated  in  such  Prospectus
         supplement or post-effective amendments;

                                   (viii)  use its  reasonable  best  efforts to
         cause the Transfer  Restricted  Securities  covered by the Registration
         Statement  to be rated  with the  appropriate  rating  agencies,  if so
         requested by the Holders of a majority in aggregate principal amount of
         Notes covered thereby or the underwriter(s), if any;

                                   (ix)  in the  case  of a  Shelf  Registration
         Statement,   furnish   to  each   selling   Holder   and  each  of  the
         underwriter(s),  if any,  without  charge,  at  least  one  copy of the
         Registration Statement, as first filed with the Commission, and of each
         amendment  thereto,  including all documents  incorporated by reference
         therein and all exhibits  (including exhibits  incorporated  therein by
         reference);

                                   (x)  in  the  case  of a  Shelf  Registration
         Statement,   deliver   to  each   selling   Holder   and  each  of  the
         underwriter(s),   if  any,  without  charge,  as  many  copies  of  the
         Prospectus (including each preliminary prospectus) and any amendment or
         supplement thereto as such Persons reasonably may request;  the Company
         hereby  consents  to the use of the  Prospectus  and any  amendment  or
         supplement  thereto  by each of the  selling  Holders  and  each of the
         underwriter(s), if any, in connection with the offering and the sale of
         the Transfer  Restricted  Securities  covered by the  Prospectus or any
         amendment or supplement thereto;

                                   (xi)  in the  case  of a  Shelf  Registration
         Statement,  enter  into  such  agreements  (including  an  underwriting
         agreement),  and make such representations and warranties, and take all
         such other  actions in  connection  therewith  in order to  expedite or
         facilitate  the  disposition  of  the  Transfer  Restricted  Securities
         pursuant to any Registration  Statement contemplated by this Agreement,
         all to  such  extent  as may be  reasonably  requested  by any  Initial
         Purchaser  or by  any  Holder  of  Transfer  Restricted  Securities  or
         underwriter in

         connection  with  any  sale  or  resale  pursuant  to any  Registration
         Statement  contemplated  by this  Agreement;  and in connection with an
         Underwritten Registration, the Company shall:

                                             (A) upon  request,  furnish to each
                  selling Holder and each underwriter, if any, in such substance
                  as they may reasonably  request and as are customarily made by

                  offerings,  upon the date of the  effectiveness  of the  Shelf
                  Registration Statement:

                           the Board,  its President or a Vice President and (z)
                           the  Chief   Financial   Officer   of  the   Company,

                           such parties may reasonably request;

                                                     (2) an  opinion,  dated the
                           date of the  effectiveness of the Shelf  Registration
                           Statement, of counsel for the Company,  covering such
                           matters as such  parties may  reasonably  request and
                           containing such qualifications and assumptions as are
                           customary  for  such  opinions,   and  in  any  event
                           including a statement to the effect,  generally, that
                           such counsel has  participated  in  conferences  with
                           officers  and other  representatives  of the Company,
                           representatives of the independent public accountants
                           for   the    Company,    the   Initial    Purchasers'
                           representatives  and the Initial  Purchasers' counsel
                           in   connection   with   the   preparation   of  such
                           Registration Statement and the related Prospectus and
                           have  considered  the  matters  required to be stated
                           therein  and  the   statements   contained   therein,
                           although such counsel has not independently  verified
                           the  accuracy,   completeness  or  fairness  of  such
                           statements;  and that such counsel  advises  that, on
                           the basis of the foregoing (relying as to materiality
                           upon facts  provided to such  counsel by officers and
                           other  representatives  of the  Company  and  without
                           independent investigation or verification),  no facts
                           came to such  counsel's  attention  that  caused such
                           counsel to believe that the  applicable  Registration
                           Statement, at the time such Registration Statement or
                           any    post-effective    amendment   thereto   became
                           effective,   contained  an  untrue   statement  of  a
                           material  fact or omitted  to state a  material  fact
                           required to be stated  therein or  necessary  to make
                           the statements  therein not  misleading,  or that the
                           Prospectus  contained in such Registration  Statement
                           as of its date,  contained  an untrue  statement of a
                           material  fact or omitted  to state a  material  fact
                           necessary in order to make the statements therein, in
                           light of the  circumstances  under  which  they  were
                           made, not misleading. Without limiting the foregoing,
                           such  counsel  may state  further  that such  counsel
                           assumes   no   responsibility   for,   and   has  not
                           independently investigated or verified, the accuracy,
                           completeness or fairness of the financial statements,
                           notes  and   schedules  and  other   statistical   or
                           financial data included in any Registration Statement
                           contemplated   by  this   Agreement  or  the  related
                           Prospectus; and

                                                     (3) a comfort letter, dated
                           the   date  of  the   effectiveness   of  the   Shelf

                  and  certificates  as  may be  reasonably  requested  by  such
                  parties to evidence  compliance with clause (A) above and with
                  any  customary   conditions   contained  in  the  underwriting
                  agreement  or  other  agreement  entered  into by the  Company
                  pursuant to this clause (xi), if any.

                  warranties of the Company  contemplated in clause (A)(1) above
                  cease to be true and correct, the Company shall so advise each
                  of the Initial Purchasers and the underwriter(s),  if any, and
                  each  selling  Holder  promptly  and,  if  requested  by  such
                  Persons, shall confirm such advice in writing;

                                   (xii)  in the  case of a  Shelf  Registration
         Statement,   prior  to  any  public  offering  of  Transfer  Restricted
         Securities, cooperate with the selling Holders, the underwriter(s),  if
         any, and their  respective  counsel in connection with the registration

         all other acts or things  reasonably  necessary  or advisable to enable
         the  disposition  in  such  jurisdictions  of the  Transfer  Restricted
         Securities  covered  by the  Shelf  Registration  Statement;  provided,
         however,  that none of the Company or any of its subsidiaries  shall be
         required to register  or qualify as a foreign  corporation  where it is
         not now so qualified or to take any action that would subject it to the
         service of process  in suits or to  taxation,  other than as to matters
         and  transactions  relating  to  the  Registration  Statement,  in  any
         jurisdiction where it is not now so subject;

                                   (xiii)  in the  case of a Shelf  Registration
         Statement,  shall  issue,  upon the  request of any Holder of  Transfer
         Restricted  Securities  covered  by the Shelf  Registration  Statement,

         sold by such Holder;  such Exchange  Notes to be registered in the name
         of such  Holder  or in the name of the  purchaser(s)  of such  Exchange

         not  bearing  any  restrictive   legends;   and  enable  such  Transfer
         Restricted  Securities to be in such  denominations  and  registered in
         such names as the Holders or the underwriter(s), if any, may reasonably
         request  at least  two  business  days  prior  to any sale of  Transfer
         Restricted Securities made by such underwriter(s);

         the  Transfer   Restricted   Securities  covered  by  the  Registration
         Statement to be registered with or approved by such other  governmental
         agencies or  authorities  as may be reasonably  necessary to enable the
         seller or sellers thereof or the underwriter(s),  if any, to consummate
         the disposition of such Transfer Restricted Securities,  subject to the
         proviso contained in clause (xii) above;

                                   (xvi) if any fact or  event  contemplated  by
         clause  (c)(iii)(D)  above  shall  exist or have  occurred,  prepare  a
         supplement or post-effective amendment to the Registration Statement or
         related Prospectus or any document incorporated therein by reference or
         file any other  required  document so that, as thereafter  delivered to
         the purchasers of Transfer Restricted  Securities,  the Prospectus will
         not contain an untrue statement of a material fact or omit to state any
         material fact necessary to make the statements therein not misleading;

                                   (xvii) provide CUSIP numbers for all Transfer

         diligence  investigation  by any  underwriter  that is  required  to be
         retained in accordance  with the rules and regulations of the NASD, and
         use its reasonable best efforts to cause such Registration Statement to
         become  effective  and  approved  by  such  governmental   agencies  or
         authorities as may be necessary to enable the Holders selling  Transfer
         Restricted  Securities to consummate  the  disposition of such Transfer
         Restricted Securities;  provided,  however, that none of the Company or
         any of its  subsidiaries  shall be required to register or qualify as a
         foreign  corporation  where it is not now so  qualified  or to take any
         action  that would  subject it to the service of process in suits or to
         taxation,  other than as to matters  and  transactions  relating to the
         Registration  Statement,  in any  jurisdiction  where  it is not now so
         subject;

                                   (xix)   otherwise  use  its  reasonable  best
         efforts to comply  with all  applicable  rules and  regulations  of the

         soon as  practicable,  a consolidated  earnings  statement  meeting the
         requirements   of  Rule  158  (which  need  not  be  audited)  for  the
         twelve-month  period (A) commencing at the end of any fiscal quarter in
         which  Transfer  Restricted  Securities are sold to  underwriters  in a
         "firm commitment" or "best efforts" Underwritten Offering or (B) if not
         sold to  underwriters  in such an  offering,  beginning  with the first
         month of the  Company's  first  fiscal  quarter  commencing  after  the
         effective date of the Registration Statement,

         under  the  TIA  not  later  than  the  effective  date  of  the  first
         Registration  Statement required by this Agreement,  and, in connection
         therewith,  cooperate  with the  Trustee and the Holders to effect such
         changes to the Indenture as may be required for such Indenture to be so
         qualified in accordance  with the terms of the TIA; and execute and use

                                   (xxi)  provide  promptly  to each Holder upon
         request  each  document  filed  with  the  Commission  pursuant  to the
         requirements of Section 13 and Section 15 of the Exchange Act.

                           Each  Holder  agrees  that  by its  acquisition  of a
         Transfer  Restricted  Security,  upon  receipt of any  notice  from the
         Company of the  existence of any fact of the kind  described in Section
         6(c)(iii)(D) hereof, such Holder will forthwith discontinue disposition
         of  Transfer   Restricted   Securities   pursuant  to  the   applicable
         Registration Statement until such Holder's receipt of the copies of the
         supplemented or amended  Prospectus  contemplated by Section  6(c)(xvi)
         hereof, or until it is advised in writing (the "Advice") by the Company
         that the use of the Prospectus may be resumed,  and has received copies
         of any  additional or  supplemental  filings that are  incorporated  by
         reference in the Prospectus. If so directed by the Company, each Holder
         will  deliver to the Company  (at the  Company's  expense)  all copies,
         other than permanent file copies then in such Holder's  possession,  of
         the Prospectus  covering such Transfer  Restricted  Securities that was
         current at the time of receipt of such notice. In the event the Company
         shall give any such notice, the time period regarding the effectiveness
         of such  Registration  Statement set forth in Section 3 or 4 hereof, as
         applicable,  shall be  extended by the number of days during the period
         from and  including  the date of the giving of such notice  pursuant to
         Section 6(c)(iii)(D) hereof to and including the date when each selling
         Holder covered by such  Registration  Statement shall have received the
         copies  of the  supplemented  or  amended  Prospectus  contemplated  by
         Section 6(c)(xvi) hereof or shall have received the Advice.

                  7.       Registration Expenses.

                  All  expenses  incident  to the  Company's  performance  of or
compliance  with this  Agreement  will be borne by the  Company,  regardless  of
whether  a  Registration   Statement   becomes   effective,   including  without
limitation: (i) all registration and filing fees and expenses (including filings

and expenses of compliance with federal securities and applicable state Blue Sky

(including the expenses of any special audit and comfort letters  required by or

                  The Company  will,  in any event,  bear its internal  expenses
(including,  without  limitation,  all salaries and expenses of its officers and
employees  performing  legal or accounting  duties),  the expenses of any annual
audit  and the fees and  expenses  of any  Person,  including  special  experts,
retained by the Company.

                  8.       Indemnification and Contribution.

                           (a) In connection with a Shelf Registration Statement
or in  connection  with any  delivery of a  Prospectus  contained in an Exchange

indemnify  and hold  harmless  each  Holder of  Transfer  Restricted  Securities
included  within any such Shelf  Registration  Statement and each  participating

several,  or any action in respect thereof  (including,  but not limited to, any
loss,  claim,  damage,  liability or action  relating to purchases  and sales of
Notes or Exchange  Notes) to which such  Participant or  controlling  person may
become  subject,  under the Securities  Act or otherwise,  insofar as such loss,
claim,  damage,  liability  or action  arises out of, or is based upon,  (i) any
untrue statement or alleged untrue statement of a material fact contained in any
preliminary  Prospectus,   Registration  Statement  or  Prospectus,  or  in  any
amendment  or  supplement  thereto or (ii) the  omission or alleged  omission to
state therein a material fact required to be stated therein or necessary to make
the statements  therein not  misleading,  and shall  reimburse each  Participant
promptly upon demand for any legal or other expenses reasonably incurred by such
Participant in connection with investigating or defending or preparing to defend
against any such loss, claim,  damage,  liability or action as such expenses are
incurred; provided however that the Company shall not be liable in any such case
to the extent that any such loss, claim, damage, liability or action directly or
indirectly  arises out of, or is based  upon,  any untrue  statement  or alleged
untrue statement or omission or alleged  omission made in any such  Registration
Statement or any  prospectus  forming  part thereof or in any such  amendment or
supplement in reliance upon and in conformity with written information furnished
to the Company by or on behalf of any  Participant  specifically  for  inclusion
therein. The foregoing indemnity agreement is in addition to any liability which
the Company may otherwise have to any Participant.

                           (b)  Each  Participant,  severally  and not  jointly,
shall  indemnify  and  hold  harmless  the  Company,  its  directors,  officers,
employees or agents and each Person, if any, who controls the Company within the
meaning of Section 15 of the Securities  Act, from and against any loss,  claim,
damage or  liability,  joint or several,  or any action in respect  thereof,  to
which  the  Company  or any such  director,  officer,  employees  or  agents  or
controlling  person may become  subject,  under the Securities Act or otherwise,
insofar as such loss,  claim,  damage,  liability or action arises out of, or is
based upon, (i) any untrue  statement or alleged untrue  statement of a material
fact  contained  in  any  preliminary  Prospectus,   Registration  Statement  or
Prospectus,  or in any amendment or  supplement  thereto or (ii) the omission or
alleged  omission to state therein a material fact required to be stated therein
or necessary to make the  statements  therein not  misleading,  but in each case
only to the extent that the untrue  statement  or alleged  untrue  statement  or
omission or alleged  omission was made in reliance upon and in  conformity  with
written information furnished to the Company by or on behalf of that Participant
specifically for inclusion herein,  and shall reimburse the Company and any such
director,  officer, employees or agents or controlling person promptly on demand
for any legal or other expenses  reasonably  incurred by the Company or any such
director,  officer, employees or agents or controlling person in connection with
investigating or defending or preparing to defend against any such loss,  claim,
damage,  liability  or action  as such  expenses  are  incurred.  The  foregoing
indemnity  agreement is in addition to any liability  which any  Participant may
otherwise have to the Company or any such director,  officer, employee, agent or
controlling person.

                           (c) Promptly  after receipt by an  indemnified  party
under this Section 8 of notice of any claim or the  commencement  of any action,
the indemnified party shall, if a claim in respect thereof is to be made against
the indemnifying  party under this Section 8, notify the  indemnifying  party in
writing of the claim or the commencement of that action; provided, however, that
the  failure  to notify the  indemnifying  party  shall not  relieve it from any
liability  which it may have  under  this  Section 8 except to the extent it has
been  materially  prejudiced  by such failure and,  provided  further,  that the
failure to notify the indemnifying party shall not relieve it from any liability
which it may have to an indemnified  party  otherwise than under Section 8(a) or
8(b) hereof. If any such claim or action shall be brought against an indemnified
party,  and  it  shall  have  notified  the  indemnifying  party  thereof,   the
indemnifying  party shall be entitled to participate  therein and, to the extent
that it wishes, jointly with any other similarly notified indemnifying party, to
assume  the  defense  thereof  with  counsel  reasonably   satisfactory  to  the
indemnified  party.  After notice from the indemnifying party to the indemnified
party of its  election  to assume  the  defense  of such  claim or  action,  the
indemnifying  party  shall not be liable to the  indemnified  party  under  this
Section  8 for  any  legal  or  other  expenses  subsequently  incurred  by  the
indemnified  party in connection  with the defense thereof other than reasonable
costs of investigation; provided, however, that the indemnified party shall have
the right to employ counsel to represent jointly the indemnified party and those
other  Participants  and its  respective  officers,  employees  and  controlling
persons who may be subject to  liability  arising out of any claim in respect of
which  indemnity  may be  sought by the  Participants  by an  indemnified  party
against  the  indemnifying  party  under  this  Section 8 if, in the  reasonable
judgment of the indemnified  party it is advisable for the indemnified party and
those  Participants,  officers,  employees and controlling persons to be jointly
represented by separate counsel, and in that event the fees and expenses of such
separate counsel shall be paid by the indemnifying  party. In no event shall the
indemnifying  parties  be  liable  for the fees and  expenses  of more  than one
counsel (in addition to local counsel) for all indemnified parties in connection
with any  proceeding  or  related  proceedings.  Each  indemnified  party,  as a
condition of the indemnity agreements contained in Section 8(a) and 8(b) hereof,
shall use its best  efforts  to  cooperate  with the  indemnifying  party in the
defense of any such action or claim. No indemnifying party shall (i) without the
prior written  consent of the  indemnified  parties  (which consent shall not be
unreasonably  withheld),  settle or  compromise  or  consent to the entry of any
judgment  with  respect to any  pending or  threatened  claim,  action,  suit or
proceeding in respect of which  indemnification  or  contribution  may be sought
hereunder  (whether  or not the  indemnified  parties  are  actual or  potential
parties to such claim or action) unless such  settlement,  compromise or consent
includes an unconditional  release of each indemnified  party from all liability
arising out of such claim, action, suit or proceeding, or (ii) be liable for any
settlement  of any such  action  effected  without its  written  consent  (which
consent  shall not be  unreasonably  withheld),  but if settled with its written
consent or if there is a final  judgment  for the  plaintiff in any such action,
the  indemnifying  party agrees to indemnify and hold  harmless any  indemnified
party from and against any loss or  liability  by reason of such  settlement  or
judgment in accordance with this Section 8.

                           (d)  If the  indemnification  provided  for  in  this
Section  8 shall  for any  reason  be  unavailable  to or  insufficient  to hold
harmless an indemnified party under Section 8(a) or 8(b) in respect of any loss,
claim,  damage or  liability,  or any action in  respect  thereof,  referred  to
therein,  then each  indemnifying  party  shall,  in lieu of  indemnifying  such
indemnified party,  contribute to the amount paid or payable by such indemnified
party as a result of such loss, claim, damage or liability, or action in respect
thereof,  in such  proportion  as shall be  appropriate  to reflect the relative
fault of the  Company  on the one hand and the  Participants  on the other  with
respect to the  statements  or  omissions  which  resulted in such loss,  claim,
damage or liability, or action in respect thereof, as well as any other relevant

                                       18




<PAGE>
equitable  considerations.  The relative  fault shall be determined by reference
to,  among other  things,  whether the untrue or alleged  untrue  statement of a
material  fact or omission or alleged  omission to state a material fact relates
to information  supplied by the Company or the  Participants,  the intent of the
parties and their relative  knowledge,  access to information and opportunity to
correct or prevent such statement or omission.  The Company and the Participants
agree that it would not be just and equitable if contributions  pursuant to this
Section  8(d)  were  to be  determined  by  pro  rata  allocation  (even  if the
Participants were treated as one entity for such purpose) or by any other method
of  allocation  which does not take into  account the  equitable  considerations
referred  to herein.  The amount  paid or payable by an  indemnified  party as a
result of the loss,  claim,  damage or liability,  or action in respect thereof,
referred to above in this  Section  8(d) shall be deemed to include,  subject to
limitations  set forth above,  for purposes of this Section  8(d),  any legal or
other expenses  reasonably incurred by such indemnified party in connection with
investigating  or  defending  any such  action  or  claim.  Notwithstanding  the
provisions of this Section 8(d), no  Participant  shall be required to indemnify
or contribute any amount in excess of the amount by which  proceeds  received by
such Participant from an offering of the Notes exceeds the amount of any damages
which such  Participant  has otherwise paid or become liable to pay by reason of
any untrue or alleged  untrue  statement  or  omission or alleged  omission.  No
Person  guilty of  fraudulent  misrepresentation  (within the meaning of Section
11(f) of the Securities Act) shall be entitled to  contribution  from any Person
who was not  guilty  of such  fraudulent  misrepresentation.  The  Participants'
obligations  to  contribute as provided in this Section 8(d) are several and not
joint.  The remedies  provided for in this Section 8 are not exclusive and shall
not limit any  rights  or  remedies  which may  otherwise  be  available  to any
indemnified party at law or in equity.

                  9. Rule 144A.

                  The Company hereby agrees with each Holder, for so long as any
Transfer  Restricted  Securities  remain  outstanding,  to make available to any
Holder or beneficial owner of Transfer Restricted  Securities in connection with
any sale  thereof and any  prospective  purchaser  of such  Transfer  Restricted
Securities from such Holder or beneficial  owner,  the  information  required by
Rule  144A(d)(4)  under the  Securities  Act in order to permit  resales of such
Transfer Restricted Securities pursuant to Rule 144A.

                  10.      Participation in Underwritten Registrations.

                  No Holder may  participate  in any  Underwritten  Registration
hereunder  unless  such  Holder  (a)  agrees  to  sell  such  Holder's  Transfer
Restricted  Securities on the basis  provided in any  underwriting  arrangements
approved by the Persons entitled  hereunder to approve such arrangements and (b)
completes  and  executes  all  reasonable  questionnaires,  powers of  attorney,
indemnities,  underwriting agreements,  "lock-up" agreements and other documents
required under the terms of such underwriting arrangements.

                  11.      Selection of Underwriters.

                  The Holders of Transfer  Restricted  Securities covered by the
Shelf  Registration  Statement  who  desire  to do so  may  sell  such  Transfer
Restricted  Securities in an  Underwritten  Offering.  In any such  Underwritten
Offering,  the investment  banker or investment  bankers and manager or managers
that will  administer the offering will be selected by the Holders of a majority
in aggregate principal amount of the

                                       19

<PAGE>
Transfer Restricted  Securities included in such offering;  provided,  that such
investment bankers and managers must be reasonably satisfactory to the Company.

                  12.      Miscellaneous.

                           (a)  Remedies.   The  Company  agrees  that  monetary
         damages   (including   Liquidated   Damages)   would  not  be  adequate
         compensation  for any loss  incurred by reason of a breach by it of the
         provisions of this  Agreement and hereby agrees to waive the defense in
         any  action  for  specific  performance  that a remedy  at law would be
         adequate.

                           (b) No Inconsistent Agreements.  The Company will not
         on or after the date of this  Agreement  enter into any agreement  with
         respect to its securities that is inconsistent  with the rights granted
         to the  Holders  in this  Agreement  or  otherwise  conflicts  with the
         provisions  hereof.  The rights granted to the Holders hereunder do not
         in any way  conflict  with and are not  inconsistent  with  the  rights
         granted to the holders of the Company's  securities under any agreement
         in effect on the date hereof.

                           (c)  Adjustments  Affecting  the Transfer  Restricted
         Securities.  The Company will not take any action, or permit any change
         to occur,  with respect to Transfer  Restricted  Securities  that would
         materially  and  adversely   affect  the  ability  of  the  Holders  to
         Consummate  any Exchange Offer unless such action or change is required
         by applicable law.

                           (d)  Amendments  and Waivers.  The provisions of this
         Agreement may not be amended, modified or supplemented,  and waivers or
         consents to or departures  from the provisions  hereof may not be given
         unless the Company  has  obtained  the written  consent of Holders of a
         majority of the  outstanding  principal  amount of Transfer  Restricted
         Securities.  Notwithstanding  the  foregoing,  a waiver or  consent  to
         departure  from the provisions  hereof that relates  exclusively to the
         rights of Holders whose  securities are being tendered  pursuant to the
         Exchange  Offer and that does not affect  directly  or  indirectly  the
         rights  of  other  Holders  whose  securities  are not  being  tendered
         pursuant  to such  Exchange  Offer  may be  given by the  Holders  of a
         majority of the  outstanding  principal  amount of Transfer  Restricted
         Securities being tendered or registered.

                           (e)  Notices.  All notices  and other  communications
         provided  for or  permitted  hereunder  shall  be  made in  writing  by
         hand-delivery,   first-class  mail  (registered  or  certified,  return
         receipt  requested),  telex,  telecopier,  or air courier  guaranteeing

                           (f)  Successors  and Assigns.  This  Agreement  shall
         inure to the benefit of and be binding upon the  successors and assigns
         of each of the parties,  including  without  limitation and without the
         need  for  an  express  assignment,   subsequent  Holders  of  Transfer
         Restricted Securities; provided, however, that this Agreement shall not
         inure to the benefit of or be binding  upon a successor  or assign of a
         Holder  unless  and to the extent  such  successor  or assign  acquired
         Transfer Restricted Securities from such Holder.

                           (g)  Counterparts.  This Agreement may be executed in

         without regard to the conflict of law rules thereof.

                           (j)  Severability.  In the event that any one or more
         of the provisions  contained herein, or the application  thereof in any
         circumstance, is held invalid, illegal or unenforceable,  the validity,
         legality  and  enforceability  of any such  provision  in  every  other
         respect and of the remaining  provisions  contained herein shall not be

                           (k) Entire  Agreement.  This Agreement  together with
         the Purchase  Agreement and the Indenture is intended by the parties as
         a final expression of their agreement and intended to be a complete and
         exclusive  statement of the agreement and  understanding of the parties
         hereto in respect of the subject matter contained herein.  There are no
         restrictions,  promises,  warranties or undertakings,  other than those
         set forth or referred to herein with respect to the registration rights
         granted  by  the  Company  with  respect  to  the  Transfer  Restricted
         Securities.   This  Agreement   supersedes  all  prior  agreements  and
         understandings between the parties with respect to such subject matter.

                           (l)  Required  Consents.   Whenever  the  consent  or
         approval of Holders of a specified  percentage  of Transfer  Restricted
         Securities is required hereunder,  Transfer Restricted  Securities held
         by the Company or its  affiliates  (as such term is defined in Rule 405
         under the Securities  Act) shall not be counted in determining  whether
         such  consent or  approval  was given by the  Holders of such  required
         percentage.

between STARTEC GLOBAL COMMUNICATIONS  CORPORATION,  a Maryland corporation (the
"Company"),  and FIRST  UNION  NATIONAL  BANK,  as Warrant  Agent (the  "Warrant
Agent").

                  The Company  desires to issue the  warrants  (the  "Warrants")
described  herein  which  will  initially   entitle  the  holders  thereof  (the
"Holders") to purchase an aggregate of 200,226 shares of common stock, par value
$0.01 per share (the  "Common  Stock"),  of the  Company at a purchase  price of
$24.20 per share subject to the adjustments described herein, in connection with
an  offering  of 160,000  units (the  "Units"),  each  consisting  of (i) $1,000
aggregate  principal  amount of 12%  Senior  Notes due 2008  (collectively,  the
"Notes")  issued by the Company  pursuant to the provisions of the Indenture (as
defined below),  and (ii) a Warrant  initially  entitling the Holder to purchase
1.25141  shares of Common Stock,  subject to adjustment as provided  herein.  In
connection with the sale of the Units, an aggregate of 160,000  Warrants will be
issued to the purchasers of the Units.

                  The Notes and  Warrants  included in each Unit will not become
separately  transferable  until the  earliest to occur of (i) November 15, 1998,
(ii) an Exercise Event, (iii) the date the Exchange Offer Registration Statement
(as defined in the Indenture) or the Shelf Registration Statement (as defined in
the Indenture) is declared effective by the Commission (as defined) or (iv) such
other date, as Lehman Brothers Inc. shall determine (the "Separation Date").

                  The Company further desires the Warrant Agent to act on behalf
of the  Company in  connection  with the  issuance  of the  Warrants as provided
herein and the Warrant Agent is willing to so act.

                  Each  party  agrees as  follows  for the  benefit of the other
party and for the equal and ratable benefit of the Holders of Warrants:

whose  nomination for election by the Company's  stockholders  was approved by a
vote of at least  two-thirds of the members of the Board of Directors then still
in office who either were members of the Board of Directors at the  beginning of
such period or whose  election or  nomination  for  election was  previously  so
approved)  cease for any reason to  constitute a majority of the members of such
Board of Directors then in office; (iii) the sale, lease,  transfer,  conveyance
or other disposition (other than by way of merger or consolidation), in one or a

owner of securities of the surviving corporation of such merger or consolidation
representing a majority of the total voting power of the then outstanding Voting
Stock of the  surviving  corporation;  or (v) the adoption of a plan relating to
the  liquidation  or  dissolution of the Company;  provided,  however,  that the
consummation  of  the  Reorganization  shall  not  constitute  or be  deemed  to
constitute a "Change of Control."

in  an  over-the-counter  market)  for  each  Business  Day  during  the  period
commencing  15  Business  Days  before  such date and ending on the date one day
prior to such date, or if the security of a class  registered under the Exchange
Act for less than 15 consecutive  Business Days before such date, the average of
the daily closing bid prices (or such  equivalent)  for all of the Business Days
before such date for which daily  closing  bid prices are  available  (provided,
however,  that if the  closing  bid  price is not  determinable  for at least 10
Business  Days in such  period,  then  clause (i) above and not this clause (ii)
shall be used to determine Current Market Value; provided,  however, that if the

                  Participant, upon receipt by the Warrant Agent of instructions
                  given in  accordance  with the  Depositary's  and the  Warrant
                  Agent's  procedures,  the Warrant  Agent shall  reflect on its
                  books and  records  the date and an  increase in the number of
                  the Rule 144A Global  Warrant in an amount equal to the number
                  of the Regulation S  Certificated  Warrant or the Regulation S
                  Permanent  Certificated  Warrant,  as the case  may be,  to be
                  transferred,  and the Warrant  Agent  shall  cancel the Global
                  Warrant,  if any, so transferred or decrease the amount of the
                  Regulation S Permanent Global Warrant.

                  (d) Transfers to Non-U.S.  Persons at Any Time.  The following
         provisions  shall apply with  respect to any transfer of a Warrant to a
         Non-U.S. Person:

                                (i) Prior to May 21,  1999,  the  Warrant  Agent
                  shall  register  any  proposed  transfer  of  a  Warrant  to a
                  Non-U.S.   Person   only  upon   receipt   of  a   certificate
                  substantially  in the  form  of  Exhibit  C  hereto  from  the
                  proposed transferor and the proposed transferee.

                               (ii) On and after May 21, 1999, the Warrant Agent
                  shall register any proposed transfer to any Non-U.S. Person if
                  the  Warrant  to be  transferred  is a Rule 144A  Certificated
                  Warrant or an interest in the Rule 144A Global  Warrant,  upon
                  receipt of a certificate  substantially in the form of Exhibit
                  C hereto from the proposed transferor.

                              (iii)  (A)  If  the  proposed   transferor   is  a
                  Participant  holding a  beneficial  interest  in the Rule 144A
                  Global Warrant, upon receipt by the

                                       14

<PAGE>
                  Warrant Agent of the documents,  if any, required by paragraph
                  (ii) and  instructions in accordance with the Depositary's and
                  the  Warrant  Agent's  procedures,  the  Warrant  Agent  shall
                  reflect on its books and  records  the date and a decrease  in
                  the  principal  amount of the Rule 144A  Global  Warrant in an
                  amount  equal  to  the  principal  amount  of  the  beneficial
                  interest  in the Rule 144A Global  Warrant to be  transferred,
                  and (B) if the  proposed  transferee  is a  Participant,  upon
                  receipt  by  the  Warrant  Agent  of  instructions   given  in
                  accordance  with  the  Depositary's  and the  Warrant  Agent's
                  procedures,  the Warrant  Agent shall reflect on its books and
                  records the date and an increase  in the  principal  amount of
                  the  Regulation  S Global  Warrant  in an amount  equal to the
                  principal  amount of the Rule 144A Global  Warrant or the Rule
                  144A Global  Warrant,  as the case may be, to be  transferred,
                  and the Warrant Agent shall cancel the Global Warrant, if any,
                  so  transferred or decrease the amount of the Rule 144A Global
                  Warrant.

                  (e) Private Placement Legend.  Upon the transfer,  exchange or
         replacement  of  Warrants  or Warrant  Shares not  bearing  the Private
         Placement  Legend,  the Warrant Agent shall deliver Warrants or Warrant
         Shares,  as applicable,  that do not bear the Private Placement Legend.
         Upon the  transfer,  exchange  or  replacement  of  Warrants or Warrant
         Shares bearing the Private  Placement  Legend,  the Warrant Agent shall
         deliver only Warrants or Warrant Shares,  as applicable,  that bear the
         Private  Placement  Legend  unless such  transfer  or  exchange  (i) is
         effected  pursuant to an  effective  registration  statement  under the
         Securities Act, (ii) in the case of Warrant Shares, such Warrant Shares
         were acquired pursuant to an effective registration statement under the
         Securities Act, (iii) such transfer or exchange is effected pursuant to
         Rule 144 under the  Securities  Act or (iv) there is  delivered  to the
         Warrant  Agent an  Opinion of Counsel  reasonably  satisfactory  to the
         Company and the Warrant  Agent to the effect that  neither  such legend
         nor the  related  restrictions  on  transfer  are  required in order to
         maintain compliance with the provisions of the Securities Act.

                  (f) General. By its acceptance of any Warrant or Warrant Share
         bearing the Private Placement Legend,  each Holder of such a Warrant or
         Warrant Share, as applicable, acknowledges the restrictions on transfer
         of such  Warrant or Warrant  Share,  as  applicable,  set forth in this
         Warrant  Agreement and in the Private  Placement Legend and agrees that
         it shall transfer such Warrant or Warrant Share, as applicable, only as
         provided  in this  Warrant  Agreement.  The  Warrant  Agent  shall  not
         register  a  transfer  of any  Warrant or  Warrant  Share  unless  such
         transfer  complies with the restrictions on transfer of such Warrant or
         Warrant Share, as applicable,  set forth in this Warrant Agreement.  In
         connection with any transfer of Warrants or Warrant Shares, each Holder
         agrees by its acceptance of the Warrants or Warrant Shares, as

                                       15
<PAGE>

         applicable,   to  furnish  the  Warrant   Agent  or  the  Company  such
         certifications,  legal opinions or other  information as either of them
         may  reasonably  require to confirm  that such  transfer  is being made
         pursuant to an effective  registration  statement  under the Securities
         Act,  an  exemption   from,  or  a  transaction  not  subject  to,  the
         registration  requirements  of the  Securities  Act;  provided that the
         Warrant  Agent shall not be required  to  determine  (but may rely on a
         determination  made by the Company or its counsel  with respect to) the
         sufficiency  of  any  such  certifications,  legal  opinions  or  other
         information.

                  The Warrant Agent shall retain copies of all letters,  notices
and other written communications  received pursuant to this Article. The Company
shall have the right to inspect and make copies of all such letters,  notices or
other  written  communications  at  any  reasonable  time  upon  the  giving  of
reasonable written notice to the Warrant Agent.

                  SECTION  2.4.  Execution  and  Countersignature.  Two Officers
shall sign the  Warrant  Certificates  for the  Company  by manual or  facsimile
signature.  If an Officer whose signature is on a Warrant  Certificate no longer
holds  that  office  at the time the  Warrant  Agent  countersigns  the  Warrant
Certificate,  the Warrant  Certificate  shall  nevertheless  be valid. A Warrant
Certificate  shall not be valid  until an  authorized  signatory  of the Warrant
Agent manually  countersigns the Warrant Certificate.  Such authorized signature
shall be conclusive evidence that the Warrant Certificate has been countersigned
under this Agreement.

                  The Warrant  Agent  shall  initially  countersign  and deliver
Warrant Certificates  entitling the Holders thereof to purchase in the aggregate
not more than 200,226  Warrant Shares upon a written order of the Company signed
by two  Officers  or by an  Officer  and  either an  Assistant  Treasurer  or an
Assistant Secretary of the Company.

                  The Warrant Agent may appoint an agent  reasonably  acceptable
to the Company to countersign  the Warrant  Certificates.  Unless limited by the
terms of such  appointment,  such  agent may  countersign  Warrant  Certificates
whenever  the  Warrant  Agent may do so. Each  reference  in this  Agreement  to
countersignature  by the Warrant Agent includes  countersignature by such agent.
Such agent will have the same rights as the Warrant Agent for service of notices
and demands.

                  SECTION 2.5.  Certificate  Register.  The Warrant  Agent shall
keep a register  ("Certificate  Register")  of the Warrant  Certificates  and of
their transfer and exchange.  The Certificate  Register shall show the names and
addresses  of the  respective  Holders  and the  date  and  number  of  Warrants
represented on the face of each Warrant Certificate. The Company and the Warrant
Agent may deem and  treat the  Person  in whose  name a Warrant  Certificate  is
registered as the absolute  owner of such Warrant  Certificate  for all purposes
whatsoever  and neither  the Company nor the Warrant  Agent shall be affected by
notice to the contrary.

                                       16
<PAGE>
                  SECTION 2.6.  Separation  of Warrants and Notes.  (a) Prior to
the Separation Date no Warrant may be sold, assigned or otherwise transferred to
any Person unless, simultaneously with such transfer, the Warrant Agent receives
confirmation  from the  Trustee  for the  Notes  that  the  Holder  thereof  has
requested a transfer of the related Notes to the same transferee.

                  (b) On or after the  Separation  Date, the holder of a Warrant
Certificate   containing  a  Separability  Legend  may  surrender  such  Warrant
Certificate  accompanied by a written  application  to the Warrant  Agent,  duly
executed by the Holder  thereof,  for a new Warrant  Certificate or certificates
not containing the Separability Legend.

                  SECTION   2.7.   Transfer  and   Exchange.   (a)  The  Warrant
Certificates  shall be issued in registered  form only and shall be transferable
only  upon  the  surrender  of such  Warrant  Certificate  for  registration  of
transfer.  When a Warrant  Certificate  is presented to the Warrant Agent with a
request to register a transfer, the Warrant Agent shall register the transfer as
requested if the reasonable  requirements of the Warrant Agent and of Section 8-
401(1) of the Uniform  Commercial Code as in effect in the State of New York are
met;  provided,  however,  that prior to the  Separation  Date the Warrant Agent
shall not register a transfer of a Warrant Certificate and such transfer will be
void and of no effect  unless  the Notes that are a part of the same Unit as the
Warrants   represented  by  the  Warrant   Certificate  to  be  transferred  are
simultaneously transferred to the same transferee. To permit the registration of
transfers and  exchanges,  the Company shall execute and the Warrant Agent shall
countersign  Warrant  Certificates at the Warrant Agent's  request.  All Warrant
Certificates  issued  upon any  registration  of transfer or exchange of Warrant
Certificates  shall be valid  obligations  of the Company,  entitled to the same
benefits under this Agreement as the Warrant Certificates  surrendered upon such
registration of transfer or exchange. No service charge will be made to a Holder
for any  registration  of  transfer or exchange  upon  surrender  of any Warrant
Certificate  at the office of the Warrant  Agent  maintained  for that  purpose.
However,  the Company may require  payment of a sum sufficient to cover any tax,
assessment or other  governmental  charge that may be imposed in connection with
any registration of transfer or exchange of Warrant Certificates but not for any
exchange or original  issuance  (not  involving a transfer)  pursuant to Section
2.9, 3.4 or 3.5.

                  (b)  Notwithstanding any other provisions of this Section 2.7,
unless and until it is exchanged in whole or in part for Warrants in  definitive
registered form, the Global Warrant may not be transferred  except as a whole by
DTC to a nominee of DTC or by a nominee of DTC to DTC or another  nominee of DTC
or by DTC or any such  nominee to a  successor  depositary  or a nominee of such
successor  depositary.  Interests of beneficial owners in the Global Warrant may
be transferred in accordance  with the rules and procedures of DTC.  Members of,
or  participants  in,  DTC  ("Participants")  shall  have no rights  under  this
Agreement  with respect to the Global Warrant held on their behalf by DTC or the
Warrant

                                       17
<PAGE>
Agent as its custodian, and DTC may be treated by the Company, the Warrant Agent
and any agent of the Company or the Warrant Agent as the absolute  owner of such
Global  Warrant for all  purposes  whatsoever.  Notwithstanding  the  foregoing,
nothing herein shall prevent the Company,  the Warrant Agent or any agent of the
Company or the Warrant  Agent from giving  effect to any written  certification,
proxy or other authorization  furnished by DTC or impair, as between DTC and its
Participants, the operation of customary practices governing the exercise of the
rights of a Holder of any Warrants.  The registered holder of the Global Warrant
may grant proxies and otherwise authorize any person, including Participants and
persons that may hold interests through Participants, to take any action which a
Holder is entitled to take under this Agreement or the Warrants.

                  If DTC  notifies the Company that it is unwilling or unable to
continue as depositary  for the Global Warrant or Warrants or if at any time DTC
shall no longer be  eligible  under the next  sentence  of this  paragraph,  the
Company shall appoint a successor depositary with respect to the Warrants.  Each
depositary  appointed  pursuant  to this  Section  2.6 must,  at the time of its
appointment and at all times while it serves as depositary, be a clearing agency
registered  under  the  Exchange  Act  and  any  other  applicable   statute  or
regulation.  The Company will execute,  and the Warrant  Agent,  upon receipt of
written instructions from the Company, will countersign and deliver, Warrants in
definitive  registered  form in any  authorized  denominations,  in an aggregate
amount equal to the amount of the Global Warrant or Warrants  representing  such
Warrants in exchange  for such Global  Warrant or Warrants if DTC  notifies  the
Company that it is unwilling or unable to continue as depositary  for the Global
Warrant or  Warrants  or if at any time DTC shall no longer be eligible to serve
as depositary  and a successor  depositary  for the Warrants is not appointed by
the  Company  within 60 days after the Company  receives  such notice or becomes
aware of such ineligibility.

                  SECTION 2.8. Replacement Certificates.  If a mutilated Warrant
Certificate  is  surrendered  to the Warrant Agent or if the Holder of a Warrant
Certificate  claims that the Warrant  Certificate  has been lost,  destroyed  or
wrongfully   taken,  the  Company  shall  issue  and  the  Warrant  Agent  shall
countersign a replacement Warrant Certificate if the reasonable  requirements of
the  Warrant  Agent and of Section  8-405 of the Uniform  Commercial  Code as in
effect in the State of New York are met.  Such Holder shall furnish an indemnity
bond  sufficient in the judgment of the Company and the Warrant Agent to protect
the Company and the Warrant  Agent from any loss which either of them may suffer
if a Warrant  Certificate  is  replaced.  The Company and the Warrant  Agent may
charge the Holder for their expenses in replacing a Warrant  Certificate.  Every
replacement Warrant Certificate is an additional obligation of the Company.

                  SECTION 2.9. Temporary Certificates.  Until definitive Warrant
Certificates  are ready for  delivery,  the  Company may prepare and the Warrant
Agent shall countersign

                                       18
<PAGE>
temporary  Warrant   Certificates.   Temporary  Warrant  Certificates  shall  be
substantially  in the  form of  definitive  Warrant  Certificates  but may  have
variations  that  the  Company  considers   appropriate  for  temporary  Warrant
Certificates.  Without  unreasonable  delay,  the Company  shall prepare and the
Warrant Agent shall countersign definitive Warrant Certificates and deliver them
in exchange for temporary Warrant Certificates.

                  SECTION 2.10. Cancellation. (a) In the event the Company shall
purchase or otherwise acquire Warrant Certificates,  the same shall thereupon be
delivered to the Warrant Agent for cancellation.

                  (b) The  Warrant  Agent and no one else shall  cancel and may,
but shall not be required to, destroy all Warrant  Certificates  surrendered for
transfer,  exchange,  replacement,  exercise or cancellation  unless the Company
directs  the  Warrant  Agent to deliver  canceled  Warrant  Certificates  to the
Company.  The Company may not issue new Warrant  Certificates to replace Warrant
Certificates to the extent they represent  Warrants which have been exercised or
Warrants which the Company has purchased or otherwise acquired.

                                    ARTICLE 3

                                 Exercise Terms

                  SECTION 3.1.  Exercise  Price.  Each Warrant  shall  initially
entitle the Holder thereof,  subject to adjustment pursuant to the terms of this
Agreement,  to purchase  1.25141 shares of Common Stock for a per share exercise
price (the "Exercise Price") of $24.20.

                  SECTION 3.2. Exercise Periods;  Restrictions on Exercise.  (a)
Subject to the terms and  conditions  set forth  herein,  the Warrants  shall be
exercisable at any time or from time to time after November 15, 1998.

                  (b) Notwithstanding anything to the contrary in this Agreement
or the  Warrants,  the Company  shall have the right not to allow an exercise of
the Warrants (or any portion thereof) to the extent necessary in order to ensure
compliance   with  the  rules,   regulations   and   policies   of  the  Federal
Communications Commission ("FCC Rules"), and Warrants will not be exercisable by
any Holder if such  exercise  would cause the Company to be in  violation of the
Communications Act of 1934 (the "Communications  Act") or FCC Rules. The Company
will have the right  prior to the  exercise of any Warrant to require the Holder
thereof to furnish the Company with such certificates or other information as it
may  reasonably be to confirm that such exercise  would not cause the Company to
be in violation of the Communications Act or FCC Rules.

                                       19
<PAGE>

                  (c) No Warrant  shall be  exercisable  after May 15, 2008 (the
"Expiration Date").

                  (d) As a  condition  to the  exercise  prior to the end of the
Restricted  Period  of any  Regulation  S Global  Warrant  that  bears a Private
Placement Legend, each holder who proposes to exercise such Warrant must deliver
to the Company and the Warrant  Agent a written  certification  satisfactory  in
form and  substance  to the  effect set forth in Rule  903(b)(iii)(5)(ii)(A)  of
Regulation S or a legal opinion to the effect set forth in subclause (B) of such
Rule   903(b)(iii)(5)(ii).   No  such  exercise   shall  be  valid  unless  such
certification or opinion shall have been delivered.

                  SECTION 3.3.  Expiration.  Each Warrant  shall  terminate  and
become void as of the  earlier of (i) the close of  business  on the  Expiration
Date or (ii) the date such Warrant is  exercised.  The Company shall give notice
not less than 90 and not more than 120 days prior to the Expiration  Date to the
Holders of all then  outstanding  Warrants to the effect that the Warrants  will
terminate  and become void as of the close of business on the  Expiration  Date;
provided,  however, that if the Company fails to give notice as provided in this
Section  3.3,  the  Warrants  will  nevertheless  expire and become  void on the
Expiration Date.

                  SECTION  3.4.  Manner of  Exercise.  Warrants may be exercised
upon (i) surrender to the Warrant Agent at the principal  corporate trust office
of the Warrant Agent of the related Warrant Certificate,  together with the form
of election to purchase  Common Stock on the reverse  thereof duly filled in and
signed by the Holder  thereof,  and (ii) payment to the Warrant  Agent,  for the
account of the Company,  of the Exercise  Price for each Warrant Share  issuable
upon the exercise of such  Warrants then  exercised.  Such payment shall be made
(i) in cash or by certified or official  bank check  payable to the order of the
Company or by wire transfer of funds to an account designated by the Company for
such  purpose or (ii)  without  the payment of cash,  by reducing  the number of
shares of Common Stock  obtainable upon the exercise of a Warrant so as to yield
a number of shares of Common Stock upon the  exercise of such  Warrant  equal to
the  product  of (a) the  number of shares of Common  Stock  issuable  as of the
Exercise  Date upon the  exercise of such  Warrant  (if payment of the  Exercise
Price were being made in cash) and (b) the Cashless  Exercise Ratio. An exercise
of a Warrant in accordance  with the  immediately  preceding  sentence is herein
called  a  "Cashless   Exercise".   Upon  surrender  of  a  Warrant  Certificate
representing  more than one Warrant in  connection  with the holder's  option to
elect a Cashless Exercise, the number of shares of Common Stock deliverable upon
a  Cashless  Exercise  shall be equal to the  number of  shares of Common  Stock
issuable  upon the  exercise of  Warrants  that the Holder  specifies  are to be
exercised  pursuant to a Cashless  Exercise  multiplied by the Cashless Exercise
Ratio.  All provisions of this Agreement  shall be applicable  with respect to a
surrender of a Warrant Certificate pursuant to a Cashless Exercise for less than
the full number of Warrants  represented  thereby.  Subject to Section  3.2, the
rights represented by the Warrants shall be exercisable at the election of the

                                       20
<PAGE>
Holders  thereof  either in full at any time or from time to time in part and in
the event that a Warrant  Certificate is  surrendered  for exercise of less than
all the Warrants  represented  by such Warrant  Certificate at any time prior to
the  Expiration  Date,  a new Warrant  Certificate  representing  the  remaining
Warrants shall be issued.  The Warrant Agent shall  countersign  and deliver the
required  new Warrant  Certificates,  and the  Company,  at the Warrant  Agent's
request, shall supply the Warrant Agent with Warrant Certificates duly signed on
behalf of the Company for such purpose.

                  SECTION 3.5.  Issuance of Warrant  Shares.  Subject to Section
2.7,  upon the  surrender of Warrant  Certificates  and payment of the per share
Exercise  Price,  as set forth in Section 3.4, the Company shall issue and cause
the  Warrant  Agent or, if  appointed,  a transfer  agent for the  Common  Stock
("Transfer  Agent") to  countersign  and deliver to or upon the written order of
the Holder and in such name or names as the Holder may  designate a  certificate
or  certificates  for the number of full Warrant  Shares so  purchased  upon the
exercise  of such  Warrants  or  other  securities  or  property  to which it is
entitled,  registered or otherwise, to the Person or Persons entitled to receive
the same,  together  with cash as  provided  in  Section  3.6 in  respect of any
fractional   Warrant  Shares  otherwise   issuable  upon  such  exercise.   Such
certificate or  certificates  shall be deemed to have been issued and any Person
so  designated  to be named  therein  shall be deemed to have become a holder of
record of such  Warrant  Shares as of the date of the  surrender of such Warrant
Certificates  and  payment  of the  per  share  Exercise  Price,  as  aforesaid;
provided,  however,  that if, at such date,  the transfer  books for the Warrant
Shares shall be closed,  the  certificates  for the Warrant Shares in respect of
which such Warrants are then exercised shall be issuable as of the date on which
such books shall next be opened and until such date the  Company  shall be under
no duty to deliver any certificates for such Warrant Shares;  provided  further,
however,  that such transfer books,  unless otherwise required by law, shall not
be  closed  at any one time for a period  longer  than 20  calendar  days.  Each
certificate  representing Warrant Shares shall bear the Private Placement Legend
except as otherwise provided in Section 2.3(e).

                  SECTION 3.6.  Fractional Warrant Shares. The Company shall not
be required to issue fractional  Warrant Shares on the exercise of Warrants.  If
more than one Warrant  shall be  exercised  in full at the same time by the same
Holder,  the number of full  Warrant  Shares  which shall be issuable  upon such
exercise  shall be  computed  on the basis of the  aggregate  number of  Warrant
Shares purchasable  pursuant thereto.  If any fraction of a Warrant Share would,
except for the  provisions  of this  Section 3.6, be issuable on the exercise of
any Warrant (or specified portion thereof), the Company shall pay at the time of
exercise an amount in cash equal to the Current  Market Value per Warrant Share,
as  determined  on the  day  immediately  preceding  the  date  the  Warrant  is
exercised, multiplied by such fraction, computed to the nearest whole cent.

                                       21

<PAGE>
                  SECTION 3.7.  Reservation of Warrant Shares. The Company shall
at all times keep reserved out of its authorized shares of Common Stock a number
of shares  of  Common  Stock  sufficient  to  provide  for the  exercise  of all
outstanding  Warrants.  The registrar for the Common Stock (the "Warrant Agent")
shall at all times until the  Expiration  Date reserve such number of authorized
shares as shall be required  for such  purpose.  The Company will keep a copy of
this Agreement on file with the Transfer Agent.  All Warrant Shares which may be
issued  upon   exercise  of  Warrants   shall,   upon  issue,   be  fully  paid,
nonassessable, free of preemptive rights and free from all taxes, liens, charges
and  security  interests  with  respect to the issue  thereof.  The Company will
supply  such  Transfer  Agent with duly  executed  stock  certificates  for such
purpose and will itself  provide or otherwise  make available any cash which may
be payable as provided in Section 3.6. The Company will furnish to such Transfer
Agent a copy of all notices of adjustments  (and  certificates  related thereto)
transmitted to each Holder.

                  Before  taking  any action  which  would  cause an  adjustment
pursuant to Article 4 to reduce the Exercise  Price below the then par value (if
any) of the Common Stock,  the Company  shall take any and all corporate  action
which may, in the opinion of its counsel, be necessary in order that the Company
may  validly and legally  issue  fully paid and  nonassessable  shares of Common
Stock at the Exercise Price as so adjusted.

                  The Company  covenants  that all shares of Common  Stock which
may be issued  upon  exercise  of  Warrants  will,  upon  issue,  be fully paid,
nonassessable,  free of preemptive rights, free from all taxes and free from all
liens, charges and security interests,  created by or through the Company,  with
respect to the issue thereof.

                  SECTION 3.8. Compliance with Law.  Notwithstanding anything in
this  Agreement  to the  contrary,  in no event  shall a Holder be  entitled  to
exercise  a  Warrant  unless  (i)  a  registration  statement  filed  under  the
Securities  Act in  respect  of the  issuance  of the  Warrant  Shares  is  then
effective  or (ii) in the  opinion of counsel to the  Company  addressed  to the
Warrant  Agent the  exercise of such  Warrants  is exempt from the  registration
requirements of the Securities Act and such securities are qualified for sale or
exempt from qualification under the applicable  securities laws of the States or
other jurisdictions in which such holders reside.

                                    ARTICLE 4

                             Antidilution Provisions

                  SECTION 4.1. Changes in Common Stock. In the event that at any
time or from  time  to time  the  Company  shall  (i) pay a  dividend  or make a
distribution  on its Common Stock payable in shares of its Common Stock or other
equity interests of the Company, (ii) subdivide its outstanding shares of Common
Stock  into a larger  number  of  shares  of Common  Stock,  (iii)  combine  its
outstanding  shares of Common  Stock  into a smaller  number of shares of Common
Stock or (iv)  increase  or  decrease  the  number of  shares  of  Common  Stock
outstanding by  reclassification  of its Common Stock, then the number of shares
of Common Stock  issuable  upon exercise of each Warrant  immediately  after the
happening of such event shall be adjusted to a number  determined by multiplying
the number of shares of Common  Stock that such holder  would have owned or have
been  entitled  to  receive  upon  exercise  had such  Warrants  been  exercised
immediately  prior to the  happening of the events  described  above (or, in the
case of a dividend or  distribution  of Common  Stock or other shares of capital
stock,  immediately  prior to the  record  date  therefor)  by a  fraction,  the
numerator  of which  shall  be the  total  number  of  shares  of  Common  Stock
outstanding  immediately  after the happening of the events  described above and
the  denominator  of which shall be the total  number of shares of Common  Stock
outstanding  immediately  prior to the happening of the events  described above;
and  subject  to Section  4.8,  the  Exercise  Price for each  Warrant  shall be
adjusted to a number determined by dividing the Exercise Price immediately prior
to such event by the  aforementioned  fraction.  An adjustment  made pursuant to
this Section 4.1 shall become effective  immediately after the effective date of
such event, retroactive to the record date therefor in the case of a dividend or
distribution in shares of Common Stock or other shares of the Company's  capital
stock.

                  SECTION 4.2. Cash  Dividends and Other  Distributions.  In the
event that at any time or from time to time the Company shall  distribute to all
holders  of  Common  Stock  (i) any  dividend  or  other  distribution  of cash,
evidences of its indebtedness,  shares of its capital stock or any other assets,
properties or debt  securities or (ii) any options,  warrants or other rights to
subscribe  for or purchase any of the foregoing  (other than, in each case,  (w)
the issuance of any rights under a shareholder  rights plan, (x) any dividend or
distribution  described  in Section 4.1,  (y) any rights,  options,  warrants or
securities  described  in Section 4.3 and (z) any cash  dividends  or other cash
distributions from current or retained  earnings),  then the number of shares of
Common Stock  issuable upon the exercise of each Warrant shall be increased to a
number  determined by multiplying  the number of shares of Common Stock issuable
upon the exercise of such Warrant  immediately  prior to the record date for any
such dividend or distribution by a fraction, the numerator of which shall be the
Current  Market  Value  per share of Common  Stock on the  record  date for such
dividend or  distribution  and the  denominator  of which shall be such  Current
Market Value per share of Common Stock on the

                                       23

<PAGE>
record date for such dividend or distribution  less the sum of (x) the amount of
cash, if any,  distributed  per share of Common Stock and (y) the fair value (as
determined in good faith by the Board, whose determination shall be evidenced by
a board resolution filed with the Warrant Agent, a copy of which will be sent to
Holders upon request) of the portion, if any, of the distribution  applicable to
one share of Common Stock  consisting  of evidences of  indebtedness,  shares of
stock, securities,  other assets or property,  warrants, options or subscription
or purchase  rights;  and,  subject to Section 4.8, the Exercise  Price shall be
adjusted to a number determined by dividing the Exercise Price immediately prior
to such record date by the  aforementioned  fraction.  Such adjustments shall be
made whenever any distribution is made and shall become effective as of the date
of  distribution,  retroactive  to the  record  date for any such  distribution;
provided,  however,  that the  Company  is not  required  to make an  adjustment
pursuant  to this  Section 4.2 if at the time of such  distribution  the Company
makes the same  distribution  to Holders of  Warrants  as it makes to holders of
Common  Stock pro rata based on the  number of shares of Common  Stock for which
such  Warrants  are  exercisable  (whether  or not  currently  exercisable).  No
adjustment  shall be made  pursuant  to this  Section  4.2 which  shall have the
effect of decreasing the number of shares of Common Stock issuable upon exercise
of each Warrant or increasing the Exercise Price.

                  SECTION 4.3.  Rights Issue to All Holders of Common Stock.  In
the event that at any time or from time to time the  Company  shall issue to all
holders  of Common  Stock  without  any  charge,  rights,  options  or  warrants
entitling  the  holders  thereof to  subscribe  for shares of Common  Stock,  or
securities  convertible  into or  exchangeable  or exercisable for Common Stock,
entitling such holders to subscribe for or purchase  shares of Common Stock at a
price per share that is lower at the record date for such issuance than the then
Current Market Value per share of Common Stock other than in connection with the
adoption of a shareholder rights plan by the Company,  then the number of shares
of Common Stock issuable upon the exercise of each Warrant shall be increased to
a number  determined  by  multiplying  the  number of  shares  of  Common  Stock
theretofore issuable upon exercise of each Warrant by a fraction,  the numerator
of which shall be the number of shares of Common Stock  outstanding  on the date
of issuance of such rights,  options,  warrants or securities plus the number of
additional  shares of Common Stock offered for  subscription or purchase or into
or for which such  securities that are issued are  convertible,  exchangeable or
exercisable,  and the  denominator  of which  shall be the  number  of shares of
Common  Stock  outstanding  on the date of  issuance  of such  rights,  options,
warrants or securities plus the total number of shares of Common Stock which the
aggregate  consideration  expected to be received by the Company  (assuming  the
exercise or  conversion  of all such rights,  options,  warrants or  securities)
would  purchase  at the then  Current  Market  Value per share of Common  Stock.
Subject to Section 4.8, in the event of any such adjustment,  the Exercise Price
shall  be  adjusted  to a number  determined  by  dividing  the  Exercise  Price
immediately prior to such date of issuance by the aforementioned  fraction. Such
adjustment shall be made immediately after such rights,  options or warrants are
issued and shall become effective, retroactive to the record date for the

                                       24

<PAGE>
determination of stockholders entitled to receive such rights, options, warrants
or securities.  Notwithstanding  anything to the contrary in this Article IV, no
adjustment  to the  number of  Warrant  Shares  issuable  upon  exercise  of the
Warrants or to the  Exercise  Price shall be made as a result of the offering by
the  Company to all holders of its Common  Stock of rights,  options or warrants
entitling  the  holders  thereof to  subscribe  for Common  Stock or  securities
convertible  into or  exchangeable  or  exercisable  for shares of Common Stock,
resulting  from the operation of any  anti-dilution  provision in any warrant or
other security of the Company convertible into,  exercisable or exchangeable for
Common Stock of the Company,  which such warrant or security is  outstanding  on
the date of this Agreement. No adjustment shall be made pursuant to this Section
4.3 which  shall  have the effect of  decreasing  the number of shares of Common
Stock  purchasable  upon exercise of each Warrant or of increasing  the Exercise
Price.

                  SECTION 4.4. Other Issuances of Common Stock or Rights. In the
event that at any time or from time to time the  Company  shall issue (i) shares
of Common Stock  (subject to the  provisions  below),  (ii)  rights,  options or
warrants  entitling  the holder  thereof to subscribe for shares of Common Stock
(provided,  however,  that no adjustment shall be made upon the exercise of such
rights,   options  or  warrants),   or  (iii)  securities  convertible  into  or
exchangeable  or  exercisable  for  Common  Stock  (provided,  however,  that no
adjustment  shall be made upon the  conversion,  exchange  or  exercise  of such
securities (other than issuances  specified in (i), (ii) or (iii) which are made
as the result of anti- dilution adjustments in such securities)), at a price per
share at the record  date of such  issuance  that is less than the then  Current
Market  Value  per share of Common  Stock,  then the  number of shares of Common
Stock  issuable upon the exercise of each Warrant shall be increased to a number
determined  by  multiplying  the  number of shares of Common  Stock  theretofore
issuable  upon  exercise of each Warrant by a fraction,  the  numerator of which
shall be the number of shares of Common Stock outstanding immediately after such
sale or issuance  plus the number of  additional  shares of Common Stock offered
for  subscription  or  purchase  or into or for which such  securities  that are
issued are  convertible,  exchangeable  or  exercisable,  and the denominator of
which  shall be the  number of shares of Common  Stock  outstanding  immediately
prior to such sale or issuance  plus the total  number of shares of Common Stock
which  the  aggregate  consideration  expected  to be  received  by the  Company
(assuming the exercise or conversion  of all such rights,  options,  warrants or
securities, if any) would purchase at the then Current Market Value per share of
Common Stock, and subject to Section 4.8 the Exercise Price shall be adjusted to
a number  determined by dividing the Exercise  Price  immediately  prior to such
date of issuance by the  aforementioned  fraction;  provided,  however,  that no
adjustment  to the number of Warrant  Shares  issuable  upon the exercise of the
Warrants or to the Exercise  Price shall be made as a result of (i) the issuance
of shares of Common Stock under any warrants,  options or other rights  existing
on the date  hereof,  (ii) the  issuance of shares of Common  Stock in bona fide
public or private  offerings that are underwritten or in which a placement agent
is retained by the Company or (iii) the issuance of options, rights or shares of
Common Stock pursuant to any option,  under any employee  benefit plans approved
by the Board of Directors. Such

                                       25
<PAGE>
adjustments  shall  be  made  whenever  such  rights,  options  or  warrants  or
convertible  securities are issued. No adjustment shall be made pursuant to this
Section  4.4 which shall have the effect of  decreasing  the number of shares of
Common  Stock  issuable  upon  exercise  of each  warrant or of  increasing  the
Exercise Price.  For purposes of Section 4.4 only, any issuance of Common Stock,
or rights, options or warrants to subscribe for, or other securities convertible
into or  exercisable  or  exchangeable  for,  Common Stock,  which  issuance (or
agreement to issue) (A) is in exchange for or otherwise in  connection  with the
bona fide acquisition of property  (excluding any such exchange  exclusively for
cash) of any Person and (B) is at a price per share  determined  by the Board of
Directors to be equal to the fair market value  thereof at the time an agreement
in principle is reached or at the time a definitive  agreement is entered  into,
shall be deemed to have  been  made at a price  per share  equal to the  Current
Market  Value per share at the record date with  respect to such  issuance  (the
time of  closing  or  consummation  of such  exchange  or  acquisition)  if such
definitive  agreement  is  entered  into  within  90  days  of the  date of such
agreement in principle.

                  SECTION 4.5. Combination;  Liquidation. (a) Except as provided
in Section  4.5(b),  in the event of a  Combination,  each Holder shall have the
right to receive upon  exercise of the Warrants the kind and amount of shares of
capital stock or other  securities or property which such Holder would have been
entitled to receive  upon or as a result of such  Combination  had such  Warrant
been  exercised  immediately  prior  to  such  event.  Unless  paragraph  (b) is
applicable  to a  Combination,  the Company  shall provide that the surviving or
acquiring  Person (the "Successor  Company") in such Combination will enter into
an agreement with the Warrant Agent  confirming the Holders'  rights pursuant to
this Section  4.5(a) and  providing  for  adjustments,  which shall be as nearly
equivalent as may be practicable to the adjustments provided for in this Article
4. The  provisions of this Section  4.5(a) shall  similarly  apply to successive
Combinations involving any Successor Company.

                  (b) In the event of (i) a Combination  where  consideration to
the holders of Common Stock in exchange  for their  shares is payable  solely in
cash or (ii) the  dissolution,  liquidation  or winding-up  of the Company,  the
holders of the Warrants  shall be entitled to receive,  upon  surrender of their
Warrant Certificates, distributions on an equal basis with the holders of Common
Stock or other  securities,  issuable upon  exercise of the Warrants,  as if the
Warrants had been exercised  immediately  prior to such event, less the Exercise
Price.

                  In case of any  Combination  described in this Section 4.5(b),
the  surviving  or  acquiring  Person  and,  in the  event  of any  dissolution,
liquidation  or  winding-up of the Company,  the Company shall deposit  promptly
with the Warrant Agent the funds, if any, necessary to pay to the holders of the
Warrants the amounts to which they are entitled as described  above.  After such
funds and the surrendered Warrant  Certificates are received,  the Warrant Agent
is required to deliver a check in such amount as is appropriate (or, in the case

                                       26

<PAGE>
of consideration other than cash, such other consideration as is appropriate) to
such  Person  or  Persons  as it may  be  directed  in  writing  by the  Holders
surrendering such Warrants.

                  SECTION 4.6. Other Events. If any event occurs as to which the
foregoing  provisions  of this  Article  4 are not  strictly  applicable  or, if
strictly applicable,  would not, in the good faith judgment of the Board, fairly
and adequately  protect the purchase  rights of the Warrants in accordance  with
the essential  intent and principles of such  provisions,  then such Board shall
make such adjustments in the application of such provisions,  in accordance with
such essential intent and principles,  as shall be reasonably necessary,  in the
good faith opinion of such Board,  to protect such purchase rights as aforesaid,
but in no event  shall any such  adjustment  have the effect of  increasing  the
Exercise  Price or decreasing the number of shares of Common Stock issuable upon
exercise of any Warrant.

                  SECTION 4.7.  Superseding  Adjustment.  Upon the expiration of
any  rights,  options,  warrants or  conversion  or  exchange  privileges  which
resulted in  adjustments  pursuant to this  Article 4, if any thereof  shall not
have been exercised,  the number of Warrant Shares issuable upon the exercise of
each Warrant shall be readjusted pursuant to the applicable section of Article 4
as if (A) the only shares of Common Stock issuable upon exercise of such rights,
options,  warrants,  conversion or exchange privileges were the shares of Common
Stock,  if any,  actually  issued  upon the  exercise of such  rights,  options,
warrants or  conversion  or exchange  privileges  and (B) shares of Common Stock
actually issued, if any, were issuable for the  consideration  actually received
by the Company upon such  exercise  plus the  aggregate  consideration,  if any,
actually  received by the Company  for the  issuance,  sale or grant of all such
rights,  options,  warrants or conversion or exchange  privileges whether or not
exercised  and the  Exercise  Price  shall be  readjusted  inversely;  provided,
however,  that no such  readjustment  shall (except by reason of an  intervening
adjustment  under  Section  4.1) have the  effect of  decreasing  the  number of
Warrant  Shares  purchasable  upon the  exercise of each Warrant or increase the
Exercise Price by an amount in excess of the amount of the adjustment  initially
made in respect of the issuance, sale or grant of such rights, options, warrants
or conversion or exchange privileges.

                  SECTION 4.8. Minimum Adjustment.  The adjustments  required by
the preceding  Sections of this Article 4 shall be made whenever and as often as
any  specified  event  requiring  an  adjustment  shall  occur,  except  that no
adjustment  of the  Exercise  Price or the  number of  shares  of  Common  Stock
issuable  upon exercise of Warrants  that would  otherwise be required  shall be
made unless and until such adjustment either by itself or with other adjustments
not previously  made increases or decreases by at least 1% the Exercise Price or
the  number of shares  of  Common  Stock  issuable  upon  exercise  of  Warrants
immediately prior to the making of such adjustment.  Any adjustment representing
a change of less than such minimum  amount shall be carried  forward and made as
soon as such  adjustment,  together  with  other  adjustments  required  by this
Article 4 and not previously made, would result in a

                                       27

<PAGE>

minimum adjustment. For the purpose of any adjustment, any specified event shall
be  deemed  to  have  occurred  at the  close  of  business  on the  date of its
occurrence.  In computing adjustments under this Article 4, fractional interests
in Common  Stock shall be taken into account to the nearest  one-hundredth  of a
share.

                  SECTION 4.9. Notice of Adjustment. Whenever the Exercise Price
or the number of shares of Common  Stock and other  property,  if any,  issuable
upon exercise of the Warrants is adjusted, as herein provided, the Company shall
deliver to the Warrant Agent a certificate of a firm of independent  accountants
selected  by the  Board  (who may be the  regular  accountants  employed  by the
Company) setting forth, in reasonable detail, the event requiring the adjustment
and the method by which such adjustment was calculated  (including a description
of the basis on which (i) the Board  determined  the fair value of any evidences
of  indebtedness,  other  securities  or property or warrants,  options or other
subscription  or purchase rights and (ii) the Current Market Value of the Common
Stock was  determined,  if either of such  determinations  were  required),  and
specifying  the Exercise Price and the number of shares of Common Stock issuable
upon exercise of Warrants  after giving effect to such  adjustment.  The Company
shall  promptly  cause the Warrant Agent to mail a copy of such  certificate  to
each Holder in accordance  with Section 7.6. The Warrant Agent shall be entitled
to rely on such  certificate and shall be under no duty or  responsibility  with
respect to any such  certificate,  except to exhibit the same from time to time,
to any Holder desiring an inspection  thereof during reasonable  business hours.
The Warrant Agent shall not at any time be under any duty or  responsibility  to
any Holder to determine whether any facts exist which may require any adjustment
of the Exercise  Price or the number of shares of Common Stock or other stock or
property issuable on exercise of the Warrants,  or with respect to the nature or
extent of any such  adjustment when made, or with respect to the method employed
in making  such  adjustment  or the  validity  or value of any  shares of Common
Stock,  evidences of  indebtedness,  warrants,  options,  or other securities or
property.

                  SECTION  4.10.  Notice of Certain  Transactions.  In the event
that the Company shall propose to (a) pay any dividend  payable in securities of
any class to the  holders  of its  Common  Stock or to make any  other  non-cash
dividend  or  distribution  to the  holders of its Common  Stock,  (b) offer the
holders  of  its  Common  Stock  rights  to  subscribe  for or to  purchase  any
securities  convertible  into  shares of Common  Stock or shares of stock of any
class or any other  securities,  rights or options,  (c) issue any (i) shares of
Common Stock, (ii) rights,  options or warrants entitling the holders thereof to
subscribe for shares of Common Stock, or (iii)  securities  convertible  into or
exchangeable  or  exercisable  for  Common  Stock (in the case of (i),  (ii) and
(iii), if such issuance or adjustment would result in an adjustment  hereunder),
(d)  effect  any  capital  reorganization,  reclassification,  consolidation  or
merger,  (e) effect the voluntary or  involuntary  dissolution,  liquidation  or
winding-up  of the  Company or (f) make a tender  offer or  exchange  offer with
respect to the Common Stock, the Company shall within 5 days send to the Warrant
Agent and the Warrant Agent shall within 5 days send

                                       28

<PAGE>
the Holder a notice (in such form as shall be furnished to the Warrant  Agent by
the Company) of such  proposed  action or offer.  Such notice shall be mailed by
the  Warrant  Agent to the  Holders  at their  addresses  as they  appear in the
Certificate  Register,  which shall  specify the record date for the purposes of
such dividend,  distribution or rights, or the date such issuance or event is to
take place and the date of participation therein by the holders of Common Stock,
if any such date is to be fixed,  and shall briefly  indicate the effect of such
action on the Common  Stock and on the  number  and kind of any other  shares of
stock and on other  property,  if any,  and the number of shares of Common Stock
and other  property,  if any,  issuable  upon  exercise of each  Warrant and the
Exercise Price after giving effect to any adjustment pursuant to Article 4 which
will be  required  as a result of such  action.  Such  notice  shall be given as
promptly as possible and (x) in the case of any action  covered by clause (a) or
(b) above, at least 10 days prior to the record date for determining  holders of
the Common  Stock for  purposes  of such  action or (y) in the case of any other
such action,  at least 20 days prior to the date of the taking of such  proposed
action or the date of  participation  therein by the  holders  of Common  Stock,
whichever shall be the earlier.

                  SECTION 4.11.  Adjustment to Warrant Certificate.  The form of
Warrant  Certificate need not be changed because of any adjustment made pursuant
to this Article 4, and Warrant  Certificates  issued after such  adjustment  may
state  the same  Exercise  Price and the same  number of shares of Common  Stock
issuable upon exercise of the Warrants as are stated in the Warrant Certificates
initially issued pursuant to this Agreement.  The Company,  however,  may at any
time in its sole discretion  make any change in the form of Warrant  Certificate
that it may deem  appropriate to give effect to such  adjustments  and that does
not affect the substance of the Warrant Certificate, and any Warrant Certificate
thereafter issued or  countersigned,  whether in exchange or substitution for an
outstanding Warrant Certificate or otherwise, may be in the form as so changed.

                  SECTION 4.12. Exceptions to Antidilution  Provisions.  Without
limiting  any other  exception  contained  in this  Article  4, and in  addition
thereto, no adjustment need be made for:

                       (i) grants or exercises of rights  granted to  employees,
         directors or consultants of the Company or any of its  subsidiaries  or
         shares  of  Common  Stock  issued  or  granted  to such  persons  under
         equity-based  incentive or corporation  plans or otherwise,  whether or
         not upon the exercise, exchange or conversion of any such rights;

                      (ii)  options,  warrants or other  agreements or rights to
         purchase capital stock of the Company entered into prior to the date of
         the issuance of the Warrants and any issuance of shares of Common Stock
         in connection therewith;

                                       29

<PAGE>

                     (iii) rights to purchase shares of Common Stock pursuant to
         a Company plan for reinvestment of dividends or interest;

                      (iv) a  change  in the par value of shares of Common Stock
         (including a change from par value to no par value or vice versa);

                       (v) the consummation of the Reorganization; and

                      (vi) bona fide  public  offerings  or  private  placements
         pursuant to Section 4(2) of the Securities Act, Regulation D thereunder
         or  Regulation  S of any security  trading on any  national  securities
         exchange,  the Nasdaq system or in the over the counter market, or of a
         security  directly or indirectly  convertible or  exchangeable  for any
         such  security  (the latter  security  being a  "Reference  Security"),
         involving at least one investment bank of national reputation,  if such
         security is sold to investors at a price equal to the closing sale, bid
         or ask price (whichever is  customary)(less  such discount,  if any, as
         such investment bank shall reasonably  determine is necessary to permit
         the consummation of such public offering or private  placement) of such
         security or the Reference  Security on the date of the public  offering

                               Registration Rights

                  SECTION 5.1. Effectiveness of Registration Statement.  Subject
to Section 5.2, the Company shall cause to be filed pursuant to Rule 415 (or any
successor  provision)  of the  Securities  Act a  shelf  registration  statement
covering  the  issuance  by the Company of Warrant  Shares to the  Holders  upon
exercise  of the  Warrants by the  Holders  thereof and resales of Warrants  and
Warrant Shares by the holders thereof (the "Warrant Registration Statement") and
shall  use its  reasonable  best  efforts  to  cause  the  Warrant  Registration
Statement  to be declared  effective on or before 180 days after the Issue Date.
Subject to  Section  5.2,  the  Company  shall  cause the  Warrant  Registration
Statement to remain effective until the earlier of (i) the second anniversary of
the date on which the last Warrant has been exercised at a time when the Warrant
Registration  Statement  was not  effective  or when  the use of the  prospectus
contained  therein was suspended and (ii) the date when all the Warrants  and/or
Warrant Shares have been sold pursuant to the Warrant Registration Statement. In
connection the Warrant Registration Statement,  (i) the Company shall furnish to
the  Warrant  Agent,  prior to the  filing  with the  Commission,  a copy of the
Warrant Registration Statement, and each amendment thereof and each amendment or
supplement,  if any,  to the  prospectus  included  therein  and  shall  use its
reasonable best efforts to reflect in each such document,

                                       30

<PAGE>
when  filed  with  the  Commission,  such  comments  as the  Warrant  Agent  may
reasonably  propose,  (ii) the Company  shall  furnish to each  Holder,  without
charge,  at  least  one  copy  of the  Warrant  Registration  Statement  and any
post-effective amendment thereto,  including financial statements and schedules,
and, if the Holder so requests in writing, all exhibits thereto (including those
incorporated by reference),  (iii) the Company shall, for so long as the Warrant
Registration Statement is effective,  deliver to each Holder, without charge, as
many copies of the prospectus  (including each preliminary  prospectus) included
in the Warrant Registration Statement and any amendment or supplement thereto as
such Holder may reasonably  request,  and the Company consents to the proper use
of the prospectus therein and any amendment or supplement thereto by each of the
selling  Holders in connection with the offering and sale of the Warrants and/or
Warrant  Shares  covered by such  prospectus  and any  amendment  or  supplement
thereto, (iv) the Company may require each Holder of Warrants to be exercised in
connection  with the Warrant  Registration  Statement  to furnish to the Company
such  information  regarding the Holder and the distribution of such Warrants or
Warrant  Shares as the  Company  may from time to time  reasonably  request  for
inclusion  in the Warrant  Registration  Statement,  (v) the Company  shall,  if
requested,  promptly  incorporate in a prospectus  supplement or  post-effective
amendment to the Warrant  Registration  Statement such information as a majority
in interest of the Holders reasonably agree should be included therein and shall
make all  required  filings  of such  prospectus  supplement  or  post-effective
amendment  as  soon  as  notified  of the  matters  to be  incorporated  in such
prospectus  supplement or post-effective  amendment,  and (vi) the Company shall
enter  into  such  agreements   (including   underwriting   agreements)  as  are
appropriate,  customary and reasonably  necessary in connection with the Warrant
Registration Statement.  The Company will furnish the Warrant Agent with current
prospectuses  meeting  the  requirements  of the  Securities  Act in  sufficient
quantity to permit the Warrant  Agent to deliver,  at the Company's  expense,  a
prospectus  to each holder of a Warrant upon the exercise  thereof.  The Company
shall  promptly  inform  the  Warrant  Agent of any  change in the status of the
effectiveness or availability of the Warrant Registration Statement.

                  SECTION  5.2.  Suspension.   During  any  consecutive  365-day
period, the Company shall be entitled to suspend the availability of the Warrant
Registration  Statement for up to two 45 consecutive-day  periods (except during
the 45  consecutive-day  period immediately prior to the Expiration Date) if the
Company's Board determines in the exercise of its reasonable judgment that there
is a valid business  purpose for such  suspension and provides  notice that such
determination  was made by the  Company's  Board to the holders of the Warrants;
provided,  however,  that in no event  shall the Company be required to disclose
the business purpose for such suspension if the Company determines in good faith
that such business purpose must remain confidential.

                  SECTION 5.3. Demand Registration;  Repurchase of Warrants. (a)
In connection  with an Exercise  Event,  the Company will give notice thereof to
all Holders as

                                       31
<PAGE>

soon as practicable but in no event later than five Business Days following such
Exercise  Event.  Upon  request  from  Holders  of  at  least  25%  of  Warrants
outstanding, the Company shall be required to use its reasonable best efforts to
effect one  registration  under the Securities Act in respect of an underwritten
sale  of  Warrant   Shares  (a  "Demand   Registration"),   subject  to  certain
limitations,  unless an  exemption  from the  registration  requirements  of the
Securities  Act is then  available for the sale of such Warrant  Shares.  Upon a
demand,  the Company will prepare,  file and use its reasonable  best efforts to
cause to be effective within 120 days of such demand a registration statement in
respect of all Warrant  Shares that request to be included in such  registration
statement (a "Demand Registration Statement").

                  (b) The right of any Holder to include its  Warrant  Shares in
the  Demand  Registration  Statement  shall be  conditioned  upon such  Holder's
participation  and inclusion of such Holder's Warrant Shares in the underwritten
offering.  All Holders  proposing  to  distribute  Warrant  Shares  through such
underwritten  offering shall enter into an  underwriting  agreement in customary
form with the underwriter or underwriters  which shall be selected by a majority
in interest of the Holders and shall be approved by the Company,  which approval
shall   not  be   unreasonably   withheld;   provided,   (i)  that  all  of  the
representations  and warranties by, and the other agreements on the part of, the
Company to and for the benefit of the underwriters shall also be made to and for
the benefit of such Holders, (ii) that any or all of the conditions precedent to
the  obligations  of the  underwriters  shall  be  conditions  precedent  to the
obligations of such Holders,  and (iii) that no Holder shall be required to make
any  representations  or  warranties  to or  agreements  with the Company or the
underwriters other than representations, warranties or agreements regarding such
Holder or the Warrant Shares of such Holder and such Holder's intended method of
distribution  and  any  other  representations  required  by law  or  reasonably
required by the underwriter.  If any such Holder disapproves of the terms of the
underwriting,  such  Holder  may elect to  withdraw  all its  Warrant  Shares by
written notice to the Company and the managing  underwriter.  The Warrant Shares
so withdrawn shall also be withdrawn from registration.

                  (c) In connection with the Demand Registration Statement,  (i)
the Company shall furnish to the Holders distributing Warrant Shares pursuant to
the Demand Registration  Statement,  prior to the filing with the Commission,  a
copy of the  Demand  Registration  Statement  and any  post-effective  amendment
thereto,  including financial statements and schedules, and all exhibits thereto
(including those  incorporated by reference),  and each amendment or supplement,
if any, to the prospectus  included  therein and shall use its  reasonable  best
efforts to reflect in each such document,  when filed with the Commission,  such
comments as such Holders may reasonably propose,  (ii) the Company shall, for so
long as the Demand Registration Statement is effective, deliver to such Holders,
without charge,  as many copies of the prospectus  (including  each  preliminary
prospectus)  included in the Demand Registration  Statement and any amendment or
supplement  thereto as such  Holders  may  reasonably  request,  and the Company
consents to the proper use of the prospectus therein and

                                       32

<PAGE>
any amendment or supplement  thereto by the  underwriter in connection  with the
offering  and sale of the  Warrant  Shares  covered by such  prospectus  and any
amendment or supplement  thereto,  (iii) the Company may require, as a condition
to the participation of such Holder in the Demand Registration  Statement,  that
such Holder to furnish to the Company such information regarding such Holder and
the distribution of such Warrants or Warrant Shares as the Company may from time
to time reasonably request for inclusion in the Demand  Registration  Statement,
(iv) the Company  shall,  if  requested,  promptly  incorporate  in a prospectus
supplement or post-effective amendment to the Demand Registration Statement such
information as a majority in interest of such Holders reasonably agree should be
included  therein  and  shall  make  all  required  filings  of such  prospectus
supplement or post-effective  amendment as soon as notified of the matters to be
incorporated in such prospectus supplement or post-effective  amendment, (v) the
Company shall enter into such agreements (including underwriting  agreements) as
are  appropriate,  customary and  reasonably  necessary in  connection  with the
Demand Registration  Statement and (vi) the Company shall (A) make available all
material customary for reasonable due diligence  examinations in connection with
such Demand Registration Statement, (B) make such representations and warranties
to such Holders as are  customary and  reasonable in connection  with the Demand
Registration  Statement,  (C) obtain  such  opinions  of counsel to the  Company
addressed to and reasonably satisfactory to such Holders and the underwriters as
are  customary  and  reasonable  in  connection  with  the  Demand  Registration
Statement  and (D) obtain such  "comfort"  letters and updates  thereof from the
independent  certified  public  accountants  of the  Company  addressed  to such
Holders and the  underwriters as are customary and reasonable in connection with
the Demand  Registration  Statement.  The  Company  shall  promptly  inform such
Holders of any change in the status of the  effectiveness or availability of the
Demand Registration Statement.

                  (d) Notwithstanding  the foregoing,  in lieu of completing the
obligation to file the Demand Registration  Statement as set forth in subsection
(a) above,  the Company may offer to repurchase  for cash all  Warrants,  at the
Current Market Value per Warrant,  of Holders requesting the Demand Registration
Statement.

                  (e)  If  the  Company  elects  to  repurchase  Warrant  Shares
pursuant  to  subsection  (d)  above,  the  Company  shall  give  notice of such
repurchase  offer to all Holders and to the Warrant Agent.  The repurchase offer
shall  commence on the date on which the Company  gives such notice (the "Notice
Date"), and such repurchase offer shall expire at 5:00 p.m., New York City time,
on a date determined by the Company (the "expiration  date") that is at least 30
but not more than 60 calendar  days after the Notice  Date.  The  Company  shall
offer to  repurchase  for cash at Current  Market  Value the  Warrant  Shares or
Warrants  pursuant to subsection (d) above,  provided that proper tender must be
made to the Warrant Agent by the Holders prior to the  expiration  date for such
repurchase offer.

                                       33

<PAGE>
                  (f) Each Holder may, but shall not be obligated to, accept the
Company's offer to repurchase  pursuant to Section  5.3(d),  by tendering to the
Warrant Agent, on or prior to the expiration date for such repurchase offer, the
Warrant  Shares or Warrants  such  Holder  desires to have  repurchased  in such
offer,  and in  the  case  of  Warrants  tendered,  together  with  a  completed
Certificate  for  Surrender in  substantially  the form  attached to the Warrant
Certificate.  A Holder may  withdraw  all or a portion of the Warrant  Shares or
Warrants  tendered to the Warrant Agent at any time prior to the expiration date
for such  repurchase  offer.  If less  than all the  Warrants  represented  by a
Warrant  Certificate  shall  be  tendered,  such  Warrant  Certificate  shall be
surrendered  and a new Warrant  Certificate of the same tenor and for the number
of  Warrants  which were not  tendered  shall be  executed  by the  Company  and
delivered to the Warrant Agent and the Warrant Agent shall  countersign  the new
Warrant  Certificate  to the Person or  Persons  entitled  to receive  the same;
provided that the Holder of such Warrants shall be  responsible  for the payment
of any  transfer  taxes  required as a result of any change in ownership of such
Warrants.  Holders not tendering their Warrants pursuant to Section 5.3(e) shall
have no further  rights to require the  Company to effect a Demand  Registration
Statement  with respect to the Exercise  Event as to which the offer to purchase
has been made.

                  SECTION   5.4.   Liquidated   Damages.   (a)  If  the  Warrant
Registration  Statement  (i) is not declared  effective by the  Commission on or
prior to the  date  specified  for such  effectiveness  in this  Agreement  (the
"Effectiveness  Target Date"), or (ii) such Registration  Statement is filed and
declared  effective  on or  prior to the  Effectiveness  Target  Date but  shall
thereafter cease to be effective or the prospectus as contained therein fails to
be usable for its intended  purpose without being succeeded within five business
days by a post-effective  amendment to the Warrant Registration  Statement or an
amendment or supplement to such  prospectus that cures such failure and that, is
the case of a post-effective amendment, is itself immediately declared effective
(each such event referred to in clauses (i) through (ii) above, a  "Registration
Default"),  the  Company  shall pay to the holders of  Warrants  and/or  Warrant
Shares that in either case are Transfer Restricted  Securities an amount in cash
of $1.00 per  Warrant  or Warrant  Share  ("Liquidated  Damages")  for the first
90-day period (or portion thereof) following such Warrant Registration  Default.
The amount of Liquidated Damages will increase by an additional $.50 per Warrant
or Warrant  Share with  respect to each  subsequent  90-day  period (or  portion
thereof) until all  Registration  Defaults have been cured, up to a maximum rate
of  Liquidated  Damages  of $2.50 per  Warrant  or Warrant  Share.  All  accrued
Liquidated  Damages  will be paid to Holders  by the  Company on the last day of
each calendar quarter during any such payment shall have become due ("Liquidated
Damages Payment Date"). Following the cure of all Registration Defaults relating
to any  particular  Transfer  Restricted  Securities,  the accrual of Liquidated
Damages with respect to such Transfer Restricted Securities will cease.

                                       34

<PAGE>

                  All  obligations  of the  Company  set forth in the  preceding
paragraph  that have  accrued and are  outstanding  with respect to any Transfer
Restricted Security at the time such security ceases to be a Transfer Restricted
Security shall survive until such time as all such  obligations  with respect to
such Transfer Restricted Security shall have been satisfied in full.

                  Warrants  and/or  Warrant Shares shall be defined as "Transfer
Restricted Securities," until the earlier to occur of (i) the date on which such
Warrants and/or Warrant Shares have been registered under the Securities Act and
disposed of in accordance with the Warrant Registration  Statement (ii) the date
on which such Warrants  and/or Warrant Shares are eligible for  distribution  to
the public pursuant to Rule 144 under the Securities Act.

                  (b) The  Company  shall  notify the Warrant  Agent  within one
business  day after each and every  date on which an event  occurs in respect of
which Liquidated  Damages are required to be paid (an "Event Date").  Liquidated
Damages shall be paid by depositing  Liquidated  Damages with the Warrant Agent,
in trust,  for the benefit of the Holders of the Warrants and/or Warrant Shares,
on or before the applicable  Liquidated Damages Payment Date (whether or not any
payment other than Liquidated Damages is payable to such Holders),in immediately
available  funds in sums  sufficient to pay the  Liquidated  Damages then due to
such  Holders.  Each  obligation  to pay  Liquidated  Damages shall be deemed to
accrue from the applicable date of the occurrence of the Registration Default.

                  SECTION 5.5.  Blue Sky. The Company  shall use its  reasonable
best  efforts to register or qualify  the Warrant and Warrant  Shares  under all
applicable  securities laws, blue sky laws or similar laws of all  jurisdictions
in the  United  States  and  Canada in which any  Holder may or may be deemed to
purchase  Warrants and Warrant  Shares and shall use its  reasonable  efforts to
maintain such registration or qualification through the earlier of (i) such time
as all Warrants have been  exercised  and (ii) the  Expiration  Date;  provided,
however,  that the  Company  shall not be required  to qualify  generally  to do
business in any jurisdiction where it would not otherwise be required to qualify
but for this Section 5.5 or to take any action which would subject it to general
service of process or to taxation in any such jurisdiction  where it is not then
so subject.

                  SECTION 5.6.  Accuracy of Disclosure.  The Company  represents
and  warrants  to each Holder and agrees for the benefit of each Holder that (i)
the Warrant Registration  Statement or the Demand Registration Statement and any
amendment  thereto will not contain any untrue  statement of a material  fact or
omit to state a material fact required to be stated therein or necessary to make
the statements contained therein not misleading; and (ii) each of the prospectus
furnished  to such  Holder for  delivery  in  connection  with the  exercise  of
Warrants or in connection with the sale of Warrant  Shares,  as the case may be,
and the documents  incorporated by reference therein will not contain any untrue
statement  of a material  fact or omit to state a material  fact  required to be
stated therein or necessary to make

                                       35
<PAGE>

the statements contained therein, in light of the circumstances under which they
were made, not  misleading;  provided,  however,  that the Company shall have no
liability  under clause (i) or (ii) of this Section 5.5 with respect to any such
untrue statement or omission made in the Warrant  Registration  Statement or the
Demand   Registration   Statement  in  reliance  upon  and  in  conformity  with
information furnished to the Company by or on behalf of the Holders specifically
for inclusion therein.

                  SECTION 5.7.  Indemnification.  (a) In connection  with either
the Warrant  Registration  Statement or the Demand Registration  Statement,  the
Company agrees to indemnify and hold harmless each Holder of the Warrants and/or
Warrant  Shares and each person,  if any, who  controls  such Holder  within the
meaning  of the  Securities  Act or the  Exchange  Act  (each  Holder  and  such
controlling persons being referred to collectively as the "Indemnified Parties")
from and against any losses,  damages or liabilities,  joint or several,  or any
actions in respect  thereof  (including  but not limited to any losses,  claims,
damages,  liabilities or actions relating to purchases and sales of the Warrants
and/or Warrant Shares) to which each Indemnified  Party may become subject under
the  Securities  Act,  the Exchange  Act or  otherwise,  insofar as such losses,
claims,  damages,  liabilities  or  actions  arise out of or are based  upon any
untrue statement or alleged untrue statement of a material fact contained in the
Warrant Registration Statement or Demand Registration Statement or their related
prospectuses or in any amendment or supplement  thereto, or arise out of, or are
based upon,  the omission or alleged  omission to state  therein a material fact
required to be stated  therein or necessary to make the statements  therein,  in
light of the circumstances under which they were made, not misleading, and shall
reimburse,  as incurred, the Indemnified Parties for any legal or other expenses
reasonably  incurred by them in connection with  investigating  or defending any
such loss,  claim,  damage,  liability or action in respect  thereof;  provided,
however, that (i) the Company shall not be liable in any such case to the extent
that such loss,  claim,  damage or liability  arises out of or is based upon any
untrue  statement or alleged  untrue  statement or omission or alleged  omission
made in the Warrant Registration  Statement or the Demand Registration Statement
or any preliminary or final prospectus or in any amendment or supplement thereto
in reliance upon and in conformity with written  information  pertaining to such
Holder and furnished to the Company by or on behalf of such Holder  specifically
for inclusion therein,  (ii) with respect to any untrue statement or omission or
alleged  untrue  statement or omission  made in any  prospectus  relating to the
Warrant  Registration  Statement  or  the  Demand  Registration  Statement,  the
indemnity  agreement  contained  in this  subsection  (a) shall not inure to the
benefit of any person as to which there is a prospectus delivery  requirement (a
"Delivering  Seller") that sold the Warrants or the Warrant Shares,  as the case
may be, to the person asserting any such losses,  claims, damages or liabilities
to the extent that any such loss, claim,  damage or liability of such Delivering
Seller results from the fact that there was not sent or given to such person, on
or  prior to the  written  confirmation  of such  sale,  a copy of the  relevant
prospectus,  as amended and  supplemented,  provided  that (I) the Company shall
have previously furnished copies thereof to such Delivering Seller in

                                       36

<PAGE>
accordance  with this Agreement and (II) such furnished  prospectus,  as amended
and supplemented,  would have corrected any such untrue statement or omission or
alleged untrue statement or omission, and (iii) this indemnity agreement will be
in  addition to any  liability  which the  Company  may  otherwise  have to such
Indemnified Party.

                  (b)  In  connection  with  either  the  Warrant   Registration
Statement  or the Demand  Registration  Statement,  the Holders of the  Warrants
agree to  indemnify  and hold  harmless  Company and each  person,  if any,  who
controls the Company  within the meaning of the  Securities  Act or the Exchange
Act (the Company and such controlling  persons being referred to collectively as
the "Holder  Indemnified  Parties")  from and  against  any  losses,  damages or
liabilities,  joint or several, or any actions in respect thereof (including but
not limited to any losses, claims,  damages,  liabilities or actions relating to
purchases  and sales of the  Warrant  Shares) to which each  Holder  Indemnified
Party  may  become  subject  under  the  Securities  Act,  the  Exchange  Act or
otherwise, insofar as such losses, claims, damages, liabilities or actions arise
out of or are based upon any untrue  statement or alleged untrue  statement of a
material  fact  contained  in  the  Warrant  Registration  Statement  or  Demand
Registration  Statement or their  related  prospectuses  or in any  amendment or
supplement  thereto, or arise out of, or are based upon, the omission or alleged
omission to therein a material fact  required to be stated  therein or necessary
to make the statements  therein,  in light of the circumstances under which they
were  made,  not  misleading,  and shall  reimburse,  as  incurred,  the  Holder
Indemnified  Parties for any legal or other expenses reasonably incurred by them
in connection  with  investigating  or defending any such loss,  claim,  damage,
liability or action in respect thereof; provided,  however, that (i) such Holder
shall not be liable in any such case to the extent that such loss, claim, damage
or  liability  arises out of or is based upon any  untrue  statement  or alleged
untrue   statement  or  omission  or  alleged   omission  made  in  the  Warrant
Registration  Statement or the Demand Registration  Statement or any preliminary
or final  prospectus or in any amendment or supplement  thereto in reliance upon
and in  conformity  with  written  information  pertaining  to such  Holder  and
furnished  to such  Holder  by or on  behalf  of the  Company  specifically  for
inclusion therein.

                  (c) Promptly after receipt by an indemnified  party under this
Section  5 of  notice  of any  claim  or the  commencement  of any  action,  the
indemnified party shall, if a claim in respect thereof is to be made against the
indemnifying  party  under this  Section 5,  notify  the  indemnifying  party in
writing of the claim or the commencement of that action; provided, however, that
the  failure  to notify the  indemnifying  party  shall not  relieve it from any
liability  which it may have  under  this  Section 5 except to the extent it has
been  materially  prejudiced  by such failure and,  provided  further,  that the
failure to notify the indemnifying party shall not relieve it from any liability
which it may have to an indemnified  party  otherwise than under Section 5(a) or
5(b) hereof. If any such claim or action shall be brought against an indemnified
party,  and  it  shall  have  notified  the  indemnifying  party  thereof,   the
indemnifying  party shall be entitled to participate  therein and, to the extent
that it wishes, jointly with any

                                       37

<PAGE>
other similarly notified  indemnifying party, to assume the defense thereof with
counsel reasonably  satisfactory to the indemnified party. After notice from the
indemnifying  party to the  indemnified  party of its  election  to  assume  the
defense of such claim or action,  the indemnifying  party shall not be liable to
the  indemnified  party  under  this  Section 5 for any legal or other  expenses
subsequently  incurred by the  indemnified  party in connection with the defense
thereof other than reasonable costs of investigation;  provided,  however,  that
the  indemnified  party  shall  have the right to employ  counsel  to  represent
jointly  the  indemnified  party and those other  Holders  and their  respective
officers,  employees  and  controlling  persons who may be subject to  liability
arising out of any claim in respect of which  indemnity may be sought Holders by
an indemnified party against the indemnifying  party under this Section 5 if, in
the  reasonable  judgment  of the  indemnified  party  it is  advisable  for the
indemnified party and those Holders, officers, employees and controlling persons
to be jointly  represented by separate  counsel,  and in that event the fees and
expenses of such separate counsel shall be paid by the indemnifying party. In no
event shall the indemnifying parties be liable for the fees and expenses of more
than one counsel (in addition to local counsel) for all  indemnified  parties in
connection with any proceeding or related  proceedings.  Each indemnified party,
as a condition of the  indemnity  agreements  contained in Section 5(a) and 5(b)
hereof,  shall use its best efforts to cooperate with the indemnifying  party in
the defense of any such action or claim. No indemnifying party shall (i) without
the prior written consent of the indemnified parties (which consent shall not be
unreasonably  withheld),  settle or  compromise  or  consent to the entry of any
judgment  with  respect to any  pending or  threatened  claim,  action,  suit or
proceeding in respect of which  indemnification  or  contribution  may be sought
hereunder  (whether  or not the  indemnified  parties  are  actual or  potential
parties to such claim or action) unless such  settlement,  compromise or consent
includes an unconditional  release of each indemnified  party from all liability
arising out of such claim, action, suit or proceeding, or (ii) be liable for any
settlement  of any such  action  effected  without its  written  consent  (which
consent  shall not be  unreasonably  withheld),  but if settled with its written
consent or if there is a final  judgment  for the  plaintiff in any such action,
the  indemnifying  party agrees to indemnify and hold  harmless any  indemnified
party from and against any loss or  liability  by reason of such  settlement  or
judgment in accordance with this Section 5.

                  (d) If the  indemnification  provided  for in this  Section  5
shall for any reason be  unavailable  to or  insufficient  to hold  harmless  an
indemnified  party  under  Section  5(a) or 5(b) in respect of any loss,  claim,
damage or liability, or any action in respect thereof, referred to therein, then
each indemnifying  party shall, in lieu of indemnifying such indemnified  party,
contribute to the amount paid or payable by such  indemnified  party as a result
of such loss, claim, damage or liability,  or action in respect thereof, in such
proportion as shall be  appropriate to reflect the relative fault of the Company
on the one hand and the Holders on the other with respect to the  statements  or
omissions which resulted in such loss, claim, damage or liability,  or action in
respect thereof,  as well as any other relevant  equitable  considerations.  The
relative fault shall be determined by reference to, among other things,

                                       38

<PAGE>
whether the untrue or alleged untrue statement of a material fact or omission or
alleged omission to state a material fact relates to information supplied by the
Company or the Holders,  the intent of the parties and their relative knowledge,
access to  information  and  opportunity to correct or prevent such statement or
omission.  The  Company  and the  Holders  agree  that it would  not be just and
equitable if  contributions  pursuant to this Section 5(d) were to be determined
by pro rata allocation  (even if the Holders were treated as one entity for such
purpose) or by any other method of  allocation  which does not take into account
the equitable  considerations  referred to herein. The amount paid or payable by
an indemnified  party as a result of the loss,  claim,  damage or liability,  or
action in  respect  thereof,  referred  to above in this  Section  5(d) shall be
deemed to include,  subject to limitations set forth above, for purposes of this
Section  5(d),  any  legal  or  other  expenses   reasonably  incurred  by  such
indemnified party in connection with  investigating or defending any such action
or claim.  Notwithstanding  the provisions of this Section 5(d), no Holder shall
be required to  indemnify  or  contribute  any amount in excess of the amount by
which proceeds received by such Holder from an offering of the Notes exceeds the
amount of any damages which such Holder has  otherwise  paid or become liable to
pay by reason of any untrue or alleged  untrue  statement or omission or alleged
omission. No Person guilty of fraudulent  misrepresentation  (within the meaning
of Section 11(f) of the Securities Act) shall be entitled to  contribution  from
any Person who was not guilty of such fraudulent misrepresentation. The Holders'
obligations  to  contribute as provided in this Section 5(d) are several and not
joint.  The remedies  provided for in this Section 5 are not exclusive and shall
not limit any  rights  or  remedies  which may  otherwise  be  available  to any
indemnified party at law or in equity.

                  (e) The agreements contained in this section shall survive the
exercise of the Warrants pursuant to the Warrant Registration  Statement and the
sale of the Warrant Shares pursuant to the Demand  Registration  Statement,  and
shall  remain  in full  force  and  effect,  regardless  of any  termination  or
cancellation of this Agreement or any investigation  made by or on behalf of any
indemnified party.

                  SECTION 5.8.  Additional  Acts. If the issuance or sale of any
Common  Stock or other  securities  issuable  upon the  exercise of the Warrants
requires registration or approval of any governmental  authority (other than the
registration  requirements under the Securities Act), or the taking of any other
action  under  the  laws  of the  United  States  of  America  or any  political
subdivision  thereof before such  securities  may be validly  offered or sold in
compliance  with such laws,  then the Company  covenants  that it will,  in good
faith and as expeditiously as reasonably possible, use all reasonable efforts to
secure and maintain such  registration or approval or to take such other action,
as the case may be.

                  SECTION 5.9. Expenses.  All expenses incident to the Company's
performance of or compliance with its  obligations  under this Article 5 will be
borne by the Company, including,  without limitation: (i) all Commission,  stock
exchange or National

                                       39

fees and expenses  incurred in connection with compliance with state  securities
or blue sky laws,  (iii) all expenses of any Persons incurred by or on behalf of
the Company in preparing or assisting in  preparing,  printing and  distributing
the Common Shelf Registration  Statement,  the Demand Registration  Statement or
any other  registration  statement,  prospectus,  any  amendments or supplements
thereto and other  documents  relating to the performance of and compliance with
this Article 5, (iv) the fees and  disbursements  of the Warrant Agent,  (v) the
fees and  disbursements of counsel for the Company and the Warrant Agent and, in
the case of a Demand  Registration  Statement,  of counsel for the  underwriters
(vi) the fees and  disbursements  of the independent  public  accountants of the
Company,  including  the  expenses  of any  special  audits or  comfort  letters
required by or incident to such performance and compliance.  The Holders selling
Warrant  Shares  pursuant  to  the  Demand   Registration   Statement  shall  be
responsible  for any  expenses  customarily  borne by  selling  securityholders,
including  underwriting  discounts  and  commissions  and fees and  expenses  of
counsel to the selling securityholders.

                  SECTION 5.10. Listing of Warrant Shares. The Company shall use
its reasonable  best efforts to the Warrant Shares to be approved for listing in
the Nasdaq Stock Market by November 21, 1998.

                                    ARTICLE 6

                                  Warrant Agent

                  SECTION 6.1.  Appointment of Warrant Agent. The Company hereby
appoints the Warrant  Agent to act as agent for the Company in  accordance  with
the express  provisions of this  Agreement and the Warrant Agent hereby  accepts
such appointment.

                  SECTION 6.2. Right and Duties of Warrant Agent.  (a) Agent for
the Company.  In acting under this Warrant  Agreement and in connection with the
Warrant  Certificates,  the  Warrant  Agent is  acting  solely  as agent for the
Company and does not assume any  obligation or  relationship  or agency or trust
for or with any of the holders of Warrant  Certificates or beneficial  owners of
Warrants.

                  (b) The Warrant Agent may consult with counsel satisfactory to
it (who may be counsel to the Company),  and the advice of such counsel shall be
full and complete  authorization  and protection in respect of any action taken,
suffered or omitted by it  hereunder  in good faith and in  accordance  with the
advice of such counsel.

                  (c) The Warrant  Agent shall be  protected  and shall incur no
liability  for or in  respect  of any action  taken or thing  suffered  by it in
reliance upon any Warrant Certificate,

                                       40

<PAGE>
notice, direction, consent, certificate,  affidavit, statement, opinion or other
paper or  document  reasonably  believed  by it to be  genuine  and to have been
presented or signed by the proper parties.

                  (d) The Warrant  Agent shall be obligated to perform only such
duties as are specifically set forth herein and in the Warrant Certificates, and
no implied  duties or  obligations  of the Warrant Agent shall be read into this
Agreement or the Warrant Certificates.  The Warrant Agent shall not be under any
obligation  to take any  action  hereunder  which may tend to  involve it in any
expense or liability for which it does not receive  indemnity if such  indemnity
is reasonably requested. The Warrant Agent shall not be accountable or under any
duty  or  responsibility  for  the  use by  the  Company  of any of the  Warrant
Certificates  countersigned  by the  Warrant  Agent and  delivered  by it to the
Holders  or on behalf  of the  Holders  pursuant  to this  Agreement  or for the
application  by the Company of the proceeds of the  Warrants.  The Warrant Agent
shall have no duty or  responsibility  in case of any  default by the Company in
the  performance  of its  covenants  or  agreements  contained  herein or in the
Warrant  Certificates or in the case of the receipt of any written demand from a
Holder with respect to such  default,  including any duty or  responsibility  to
initiate or attempt to initiate any proceedings at law or otherwise.

                  (e) The Warrant  Agent shall not at any time be under any duty
or  responsibility  to any Holder to determine  whether any facts exist that may
require an  adjustment  of the number of shares of Common  Stock  issuable  upon
exercise of each Warrant or the Exercise Price, or with respect to the nature or
extent of any  adjustment  when made or with  respect to the method  employed or
provided to be employed  herein or in any  supplemental  agreement in making the
same. The Warrant Agent shall not be accountable with respect to the validity or
value of any shares of Common Stock or of any  securities or property  which may
at any time be issued or delivered  upon the exercise of any Warrant or upon any
adjustment  pursuant to Article 4, and it makes no  representation  with respect
thereto.  The  Warrant  Agent  shall not be  responsible  for any failure of the
Company to make any cash payment or to issue,  transfer or deliver any shares of
Common Stock or stock certificates upon the surrender of any Warrant Certificate
for the purpose of exercise or upon any adjustment  pursuant to Article 4, or to
comply with any of the covenants of the Company contained in Article 4.

                  SECTION 6.3.  Individual  Rights of Warrant Agent. The Warrant
Agent and any  stockholder,  director,  officer or employee of the Warrant Agent
may buy, sell or deal in any of the Warrants or other  securities of the Company
or its affiliates or become pecuniarily  interested in transactions in which the
Company or its affiliates  may be interested,  or contract with or lend money to
the Company or its  affiliates or otherwise act as fully and freely as though it
were not the Warrant Agent under this Agreement. Nothing herein shall preclude

                                       41

<PAGE>
the Warrant  Agent from acting in any other  capacity for the Company or for any
other legal entity.

                  SECTION 6.4.  Warrant  Agent's  Disclaimer.  The Warrant Agent
shall not be responsible for and makes no  representation  as to the validity or
adequacy  of this  Agreement  or the  Warrant  Certificates  and it shall not be
responsible  for any  statement in this  Agreement  or the Warrant  Certificates
other than its countersignature thereon.

                  SECTION 6.5.  Compensation and Indemnity.  The Company and the
Warrant  Agent have  entered  into an  agreement  pursuant  to which the Company
agrees to pay the Warrant Agent from time to time  compensation for its services
and to reimburse the Warrant Agent upon request for all reasonable out-of-pocket
expenses  incurred by it, including the reasonable  compensation and expenses of
the Warrant Agent and its directors,  officers,  agents and counsel. The Company
shall  indemnify  the  Warrant  Agent and its  directors,  officers,  agents and
counsel against any and all loss, liability, damage, claim or expense (including
agents' and attorneys' fees and expenses)  incurred by the Warrant Agent without
negligence,  bad faith or willful  misconduct  on its part  arising out of or in
connection  with  the  acceptance  or  performance  of  its  duties  under  this
Agreement.  The Warrant Agent shall notify the Company promptly of any claim for
which it may seek  indemnity.  The  Company  need not  reimburse  any expense or
indemnify  against any loss or liability  incurred by the Warrant  Agent through
wilful  misconduct,  negligence or bad faith. The Company's payment  obligations
pursuant to this Section 6.5 shall survive the termination of this Agreement.

                  To  secure  the  Company's  payment   obligations  under  this
Agreement, the Warrant Agent shall have a lien prior to the Holders on all money
or property held or collected by the Warrant Agent.

                  SECTION 6.6.  Successor  Warrant Agent. The Company agrees for
the  benefit of the  Holders  that there  shall at all times be a Warrant  Agent
hereunder  until  all  the  Warrants  have  been  exercised  or  are  no  longer
exercisable.

                  (a) The Warrant Agent may at any time resign by giving written
notice to the  Company of such  intention  on its part,  specifying  the date on
which its desired resignation shall become effective;  provided,  however,  that
such date shall not be less than 60 days after the date on which such  notice is
given unless the Company  otherwise  agrees.  The Warrant Agent hereunder may be
removed at any time by the filing with it of an instrument in writing  signed by
or on behalf of the Company  and  specifying  such  removal and the date when it
shall  become  effective,  which  date shall not be less than 60 days after such
notice is given unless the Warrant  Agent  otherwise  agrees.  Any removal under
this  Section  6.6 shall take  effect  upon the  appointment  by the  Company as
hereinafter  provided of a successor  Warrant  Agent  (which  shall be a bank or
trust company authorized under the laws of the jurisdiction of its

                                       42

<PAGE>
organization  to exercise  corporate  trust  powers) and the  acceptance of such
appointment by such successor  Warrant Agent. If a successor  Warrant Agent does
not take office  within 60 days after the retiring  Warrant  Agent resigns or is
removed,  the retiring  Warrant  Agent or the Holders of 10% of the Warrants may
petition, at the expense of the Company, any court of competent jurisdiction for
the appointment of a successor.

                  (b) In the  event  that at any time the  Warrant  Agent  shall
resign,  or shall be removed,  or shall become incapable of acting,  or shall be
adjudged a bankrupt  or  insolvent,  or shall  commence a  voluntary  case under
Federal  bankruptcy  laws, as now or hereafter  constituted,  or under any other
applicable  Federal or state  bankruptcy,  insolvency  or similar  law, or shall
consent to the  appointment  of or taking  possession by a receiver,  custodian,
liquidator,  assignee, trustee,  sequestrator (or other similar official) of the
Warrant Agent or its property or affairs,  or shall make an  assignment  for the
benefit of  creditors,  or shall admit in writing its inability to pay its debts
generally as they become due, or shall take  corporate  action in furtherance of
any such action, or a decree or order for relief by a court having  jurisdiction
in the premises  shall have been  entered in respect of the Warrant  Agent in an
involuntary  case  under  the  Federal  bankruptcy  laws,  as now  or  hereafter
constituted, or any other applicable Federal or State bankruptcy,  insolvency or
similar law, or a decree or order by a court having jurisdiction in the premises
shall  have  been  entered  for  the  appointment  of  a  receiver,   custodian,
liquidator, assignee, trustee, sequestrator (or similar official) of the Warrant
Agent or of its property or affairs,  or any public officer shall take charge or
control of the  Warrant  Agent or of its  property or affairs for the purpose of
rehabilitation,  conservation,  winding up or liquidation,  a successor  Warrant
Agent,  qualified  as  aforesaid,  shall  be  appointed  by  the  Company  by an
instrument  in  writing  filed  with  the  successor  Warrant  Agent.  Upon  the
appointment  as aforesaid of a successor  Warrant  Agent and  acceptance  by the
successor Warrant Agent of such appointment, the Warrant Agent shall cease to be
the  Warrant  Agent  hereunder;  provided,  however,  that in the  event  of the
resignation of the Warrant Agent hereunder,  such resignation shall be effective
on the  earlier  of (i) the date  specified  in the  Warrant  Agent's  notice of
resignation and (ii) the appointment and acceptance of a successor Warrant Agent
hereunder.

                  (c) Any successor  Warrant  Agent  appointed  hereunder  shall
execute,  acknowledge  and  deliver  to its  predecessor  and to the  Company an
instrument  accepting such appointment  hereunder,  and thereupon such successor
Warrant Agent, without any further act, deed or conveyance,  shall become vested
with all the rights and obligations of such  predecessor  with like effect as if
originally named as Warrant Agent hereunder, and such predecessor,  upon payment
of its charges and disbursements  then unpaid,  shall thereupon become obligated
to transfer,  deliver and pay over,  and such  successor  Warrant Agent shall be
entitled to receive,  all monies,  securities and other property on deposit with
or held by such predecessor, as Warrant Agent hereunder.

                  (d) Any corporation into which the Warrant Agent hereunder may
be merged or  consolidated,  or any  corporation  resulting  from any  merger or
consolidation to which the Warrant Agent shall be a party, or any corporation to
which the Warrant  Agent shall sell or otherwise  transfer all or  substantially
all the  corporate  trust or stock  transfer  assets and business of the Warrant
Agent, provided that it shall be qualified as aforesaid,  shall be the successor
Warrant Agent under this Agreement  without the execution or filing of any paper
or any further act on the part of any of the parties hereto.

                                    Remedies

                  SECTION  7.1.  Defaults.  It shall be deemed a "Default"  with
respect to the Company's (or its successor's)  obligations  under this Agreement
if an Exercise  Event occurs and, (i)  following  the request of at least 25% of
Holders of Warrants  outstanding,  the Company fails to use its reasonable  best
efforts to have  declared  effective  and kept  effective a Demand  Registration
Statement  as set  forth  in  Section  5.3(a),  or (ii)  the  Company  fails  to
repurchase the Warrants tendered pursuant to an offer to purchase Section 5.3(e)
in lieu of having a Demand  Registration  Statement declared  effective,  as set
forth in Section 5.3(a).

                  SECTION 7.2.  Payment  Obligations.  In the event of a Default
under this  Agreement,  the Company  shall be  obligated to increase the amounts
payable  under  Section  5.3(b) in respect of which such  Default  relates by an
amount equal to interest  thereon at a rate per annum equal to 10% from the date
of the Default to the date of payment,  which interest shall compound  quarterly
(all such payment  obligations in respect of amounts  payable under Section 5.3,
together with all such increased amounts, being the "Repurchase Obligations").

                  SECTION 7.3. Remedies.  Notwithstanding any other provision of
this  Agreement,  if a Default occurs and is continuing,  the Holders may pursue
any available  remedy to collect the  Repurchase  Obligations  or to enforce the
performance  of any  provision  of this  Agreement.  A delay or  omission by any
Holder of a Warrant in exercising, or a failure to exercise, any right or remedy
arising out of a Default  shall not impair the right or remedy or  constitute  a
waiver of or  acquiescence  in the Default.  All remedies are  cumulative to the
extent permitted by law.

                                  Miscellaneous

                  SECTION 8.1. Financial  Statements and Reports of the Company.
The Company  agrees (a) to provide to each Holder,  without cost to such Holder,
copies of the annual and quarterly  reports and documents that the Company files
with the  Commission  (to the extent such filings are accepted by the Commission
and whether or not the Company has a class of  securities  registered  under the
Securities  Exchange Act of 1934 (the "Exchange Act")) or that the Company would
be  required  to file were it subject to Section 13 or 15 of the  Exchange  Act,
within 15 days  after the date of such  filing or the date on which the  Company
would be  required  to file such  reports or  documents,  and all such annual or
quarterly reports shall include the geographic segment financial  information as
has  heretofore  been  disclosed  by the Company in its public  filings with the
Commission,  and (b) if filing such reports and documents is not accepted by the
Commission or is  prohibited  under the Exchange Act, to supply at the Company's
expense copies of such reports and documents to any prospective  Holder promptly
upon request.

                  SECTION 8.2. Third Party  Beneficiaries.  The Holders shall be
third party  beneficiaries to the agreements made hereunder between the Company,
on the one hand, and the Warrant Agent, on the other hand, and each Holder shall
have the right to enforce such  agreements  directly to the extent it deems such
enforcement  necessary  or  advisable  to  protect  its  rights or the rights of
Holders hereunder.

                  SECTION  8.3.  Rights  of  Holders.   Holders  of  unexercised
Warrants are not entitled to (i) receive dividends or other distributions,  (ii)
receive notice of or vote at any meeting of the  stockholders,  (iii) consent to
any action of the stockholders, (iv) receive notice as stockholders of any other
proceedings of the Company,  (v) exercise any preemptive rights or (vi) exercise
any other rights whatsoever as stockholders of the Company.

                  SECTION 8.4.  Amendment.  This Agreement may be amended by the
parties  hereto  without the consent of any Holder for the purpose of curing any
ambiguity,  or of curing,  correcting or supplementing  any defective  provision
contained  herein or adding or changing  any other  provisions  with  respect to
matters or questions arising under this Agreement as the Company and the Warrant
Agent may deem necessary or desirable (including without limitation any addition
or  modification to provide for compliance  with the transfer  restrictions  set
forth herein);  provided,  however,  that such action shall not adversely affect
the rights of any of the Holders.  Any amendment or supplement to this Agreement
that has an adverse  effect on the  interests of the Holders  shall  require the
written consent of the Holders of a majority of the then  outstanding  Warrants.
The consent of each Holder affected shall be required for any amendment pursuant
to which the Exercise Price would be increased

or the number of Warrant  Shares  issuable  upon  exercise of Warrants  would be
decreased  (other than pursuant to adjustments  provided herein) or the exercise
period with respect to the Warrants would be shortened.  In determining  whether
the Holders of the required  number of Warrants have concurred in any direction,
waiver or consent,  Warrants  owned by the Company or by any Person  directly or
indirectly  controlling  or  controlled  by or under  direct or indirect  common
control with the Company shall be disregarded  and deemed not to be outstanding,
except that, for the purpose of  determining  whether the Warrant Agent shall be
protected in relying on any such  direction,  waiver or consent,  only  Warrants
which the Warrant  Agent  actually  knows are so owned shall be so  disregarded.
Also, subject to the foregoing,  only Warrants  outstanding at the time shall be
considered in any such determination.

                  SECTION 8.5. Notices.  Any notice or communication shall be in

provision,  or part  thereof,  and shall not in any manner affect such clause or
provision  in any other  jurisdiction  or any other  clause or provision of this
Agreement in any jurisdiction.

No.                                               Certificate for _____ Warrants

                      WARRANTS TO PURCHASE COMMON STOCK OF
                    STARTEC GLOBAL COMMUNICATIONS CORPORATION

                  THIS CERTIFIES THAT __________,  or its registered assigns, is
the  registered   holder  of  the  number  of  Warrants  set  forth  above  (the
"Warrants").  Each Warrant  entitles the holder thereof (the  "Holder"),  at its
option  and  subject  to the  provisions  contained  herein  and in the  Warrant
Agreement  referred to below,  to purchase  from Startec  Global  Communications
Corporation,  a Maryland  corporation ("the Company"),  1.25141 shares of Common
Stock,  par value of $0.01 per share, of the Company (the "Common Stock") at the
per share  exercise  price of $24.20  (the  "Exercise  Price"),  or by  Cashless
Exercise referred to below. This Warrant  Certificate shall terminate and become
void as of the close of business on November 15, 2008 (the "Expiration Date") or
upon the exercise  hereof as to all the shares of Common Stock  subject  hereto.
The number of shares  issuable  upon  exercise of the  Warrants and the Exercise
Price per share shall be subject to adjustment from time to time as set forth in
the Warrant Agreement.

                  This Warrant  Certificate  is issued  under and in  accordance
with a Warrant  Agreement  dated as of May 21, 1998 (the  "Warrant  Agreement"),
between the Company and First Union  National Bank (the "Warrant  Agent",  which
term includes any successor Warrant Agent under the Warrant  Agreement),  and is
subject to the terms and provisions  contained in the Warrant Agreement,  to all
of which terms and provisions the Holder of this Warrant Certificate consents by
acceptance  hereof.  The  Warrant  Agreement  is hereby  incorporated  herein by
reference  and made a part  hereof.  Reference  is  hereby  made to the  Warrant
Agreement for a full statement of the respective rights,  limitations of rights,
duties and obligations of the Company,  the Warrant Agent and the Holders of the
Warrants.  Capitalized terms used but not defined herein shall have the meanings
ascribed thereto in the Warrant  Agreement.  A copy of the Warrant Agreement may
be obtained for  inspection  by the Holder  hereof upon  written  request to the
Warrant  Agent  at First  Union  national  Bank,  800 East  Main  Street,  Lower
Mezzanine, Richmond, Virginia 23219, Attention: Corporate Trust Department.

                  Subject to the terms of the Warrant  Agreement,  the  Warrants
may be  exercised  in  whole  or in part  (i) by  presentation  of this  Warrant
Certificate with the Election to Purchase attached hereto duly executed and with
the  simultaneous  payment of the Exercise Price in cash (subject to adjustment)
to the Warrant Agent for the account of the Company at the office of the Warrant
Agent or (ii) by Cashless Exercise.  Payment of the Exercise Price in cash shall
be made by certified or official  bank check payable to the order of the Company
or by wire  transfer of funds to an account  designated  by the Company for such
purpose.  Payment by Cashless Exercise shall be made without the payment of cash
by reducing the amount of

                                       A-4

<PAGE>

Common Stock that would be obtainable upon the exercise of a Warrant and payment
of the Exercise  Price in cash so as to yield a number of shares of Common Stock
upon the  exercise  of such  Warrant  equal to the  product of (1) the number of
shares of Common Stock for which such Warrant is  exercisable as of the Exercise
Date (if the  Exercise  Price were being paid in cash) and (2) a  fraction,  the
numerator of which is the excess of the Current Market Value per share of Common
Stock on the Exercise Date over the Exercise  Price per share as of the Exercise
Date and the  denominator  of which is the Current Market Value per share of the
Common Stock on the Exercise Date.

         This Warrant  requires the Holder to comply with certain  certification
and  opinion  delivery  requirements  under  certain  circumstances  in order to
validly exercise the Warrant.

                  As provided in the Warrant  Agreement and subject to the terms
and conditions  therein set forth, the Warrants shall be exercisable at any time
on or after  November  15, 1998;  provided,  however,  that no Warrant  shall be
exercisable  after May 15,  2008.  This  Warrant is  entitled  to the benefit of
certain registration rights contained in the Warrant Agreement.

                  In the event the Company enters into a Combination, the Holder
hereof will be entitled to receive  upon  exercise of the  Warrants the kind and
amount of shares of capital stock or other  securities or other property of such
surviving  entity as the Holder would have been entitled to receive upon or as a
result of the  combination  had the Holder  exercised  its Warrants  immediately
prior  to such  Combination;  provided,  however,  that in the  event  that,  in
connection with such  Combination,  consideration  to holders of Common Stock in
exchange  for  their  shares  is  payable  solely in cash or in the event of the
dissolution, liquidation or winding-up of the Company, the Holder hereof will be
entitled to receive such cash  distributions  as the Holder would have  received
had the Holder  exercised its Warrants  immediately  prior to such  Combination,
less the Exercise Price.

                  As provided in the Warrant Agreement,  the number of shares of
Common Stock  issuable upon the exercise of the Warrants and the Exercise  Price
are subject to adjustment upon the happening of certain events.

                  The Company may require payment of a sum sufficient to pay all
taxes, assessments or other governmental charges in connection with the transfer
or exchange of the Warrant  Certificates  pursuant to Section 2.6 of the Warrant
Agreement,  but not for any  exchange  or  original  issuance  (not  involving a
transfer) with respect to temporary  Warrant  Certificates,  the exercise of the
Warrants or the issuance of the Warrant Shares.

                  Upon any  partial  exercise  of the  Warrants,  there shall be
countersigned  and  issued  to  the  Holder  hereof  a new  Warrant  Certificate
representing those Warrants which were not exercised.  This Warrant  Certificate
may be exchanged at the office of the Warrant Agent

                                       A-5
<PAGE>

by  presenting  this Warrant  Certificate  properly  endorsed  with a request to
exchange this Warrant Certificate for other Warrant  Certificates  evidencing an
equal number of Warrants.  No fractional  Warrant Shares will be issued upon the
exercise of the  Warrants,  but the Company shall pay an amount in cash equal to
the Current Market Value per Warrant Share on the day immediately  preceding the
date the Warrant is  exercised,  multiplied  by the fraction of a Warrant  Share
that would be issuable on the exercise of any Warrant.

                  All shares of Common  Stock  issuable by the Company  upon the
exercise of the Warrants shall,  upon such issue, be duly and validly issued and
fully paid and non-assessable.

                  The holder in whose name the Warrant Certificate is registered
may be deemed and treated by the Company and the Warrant  Agent as the  absolute
owner of the Warrant  Certificate  for all purposes  whatsoever  and neither the
Company nor the Warrant Agent shall be affected by notice to the contrary.

                  The  Warrants do not  entitle any holder  hereof to any of the
rights of a shareholder of the Company.

                  This Warrant shall be governed by the laws of the State of New
York.

                  This Warrant  Certificate shall not be valid or obligatory for
any purpose until it shall have been countersigned by the Warrant Agent.

the Securities Act of 1933, as amended (the "Securities Act"). We hereby certify
as follows:

                  1. The offer of the  Warrants  was not made to a person in the
         United  States  (unless such person or the account held by it for which
         it is acting is excluded from the definition of "U.S.  person" pursuant
         to Rule 902(o) of  Regulation  S under the  circumstances  described in

                  2.  Either (a) at the time the buy order was  originated,  the

         behalf reasonably believed that the buyer was outside the United States
         or (b) the transaction was executed in, on or through the facilities of
         a designated  offshore securities market, and neither we nor any person
         acting on our behalf knows that the transaction was prearranged  with a
         buyer in the United States.

                  3. Neither we, any of our affiliates, nor any person acting on
         our or their  behalf,  has made any  directed  selling  efforts  in the
         United States.

         scheme to evade the registration requirements of the Securities Act.

                  5.  If  we  are a  dealer  or a  person  receiving  a  selling
         concession or other fee or remuneration in respect of the Warrants, and
         we are an officer or  director  of the  Company  or a  distributor,  we
         certify that the proposed transfer is being made in accordance with the
         provisions of Rule 904(c) of Regulation S.

11 and 12, the

                                       10
<PAGE>

the first six  scheduled  interest  payments  on the  Notes,  the  Pledgor  may,
pursuant to written  instructions  executed by the Pledgor (an "Issuer  Order"),
direct the  Trustee  to  release  from the  Collateral  Accounts  and pay to the
Holders of the Notes proceeds  sufficient to provide for payment in full of such
interest then due on the Notes; provided,  however, that in the event Collateral
is required to be  liquidated,  the Pledgor will give the Trustee at least three
Business  Days' notice.  Upon receipt of an Issuer Order,  the Trustee will take
any action  necessary to provide for the payment of the interest on the Notes to
the  Holders  of the Notes in  accordance  with the  payment  provisions  of the
Indenture  from  (and  to the  extent  of)  proceeds  of the  Collateral  in the
Collateral Accounts. Nothing in this Section 6 shall affect the Trustee's rights
to apply the  Collateral  to the  payments  of  amounts  due on the  Notes  upon
acceleration thereof.

                  (b) If the Pledgor makes any interest payment or portion of an
interest  payment for which the  Collateral  is security  from a source of funds
other than the Collateral  Accounts  ("Pledgor  Funds"),  the Pledgor may, after
payment in full of such interest payment,  direct the Trustee by Issuer Order to
release to the Pledgor or to another  party at the direction of the Pledgor (the
"Pledgor's  Designee")  proceeds from the Collateral  Accounts in an amount less
than or equal to the amount of Pledgor Funds  applied to such interest  payment.
Upon receipt of such Issuer Order by the Trustee,  the Trustee shall pay over to
the Pledgor or the Pledgor's Designee,  as the case may be, the requested amount
from proceeds in the Collateral Accounts. Concurrently with any release of funds
to the Pledgor  pursuant to this Section 6(b),  the Pledgor shall deliver to the
Trustee a  certificate  signed by an officer  of the  Pledgor  stating  that the
Pledgor  has made the  interest  payment  from a source of funds  other than the
Pledge  Account,  and that such release has been duly  authorized by the Pledgor
and  will  not  violate  any  provision  of  applicable  law or  Certificate  of
Incorporation  or the  By-laws  of the  Pledgor  or any  material  agreement  or
instrument  binding upon the Pledgor or any of its subsidiaries or any judgment,
order or decree of any governmental  body,  agency or court having  jurisdiction
over the  Pledgor  or any of its  subsidiaries  or  result  in the  creation  or
imposition  of any Lien on any assets of the  Pledgor,  except for the  security
interest granted under the Pledge Agreement.

                  (c) At least one  Business Day prior to the due date of any of
the first six scheduled interest payments on the Notes, the Pledgor covenants to
give the Trustee

                                       11

<PAGE>
(by Issuer Order) notice as to whether payment of interest will be made pursuant
to Section 6(a) or 6(b) and as to the  respective  amounts of interest that will
be paid pursuant to Section 6(a) or 6(b); provided,  however, that, in the event
Collateral  is required to be  liquidated,  the Pledgor will give the Trustee at
least three Business Days' notice. If no such notice is given, the Trustee will,
subject to Section  6(d),  act pursuant to Section 6(a) as if it had received an
Issuer Order pursuant thereto for the payment in full of the interest then due.

                  (d)  The  Trustee  shall  not be  required  to  liquidate  any
Collateral Investments in order to make any scheduled payment of interest or any
release  hereunder  unless  instructed  to do so by Issuer  Order or pursuant to
Section 13 hereof.

                  (e) Upon the  Termination  Date, the security  interest in the
Collateral  evidenced by this Pledge Agreement will automatically  terminate and
be of no further  force and  effect,  and the  Collateral,  upon  receipt by the
Trustee of an Issuer Order,  shall promptly be paid over and  transferred to the
Pledgor.

                  (f) In the  event  that  the  Collateral  held  in the  Pledge
Account  exceeds 100% of the amount  sufficient,  in the written  opinion of the
Accounting  Firm,  to provide  for  payment  in full of the first six  scheduled
interest  payments  due on the Notes (or,  in the event an  interest  payment or
payments have been made, an amount  sufficient to provide for payment in full of
all  interest  payments  remaining,  up to and  including  the  sixth  scheduled
interest  payment),  the Trustee shall release to the Pledgor,  at the Pledgor's
written  request,  accompanied by a written opinion of the Accounting  Firm, any
such excess Collateral.

                  (g)  Upon  the  release  of any  Collateral  from  the  Pledge
Account,  in accordance  with the terms of this Pledge  Agreement,  the security
interest  evidenced by this Pledge  Agreement in such released  Collateral  will
automatically terminate and be of no further force and effect.

                  (h) Nothing  contained  in Section 1, this  Section 6, Section
13, or any other provision of this Pledge Agreement shall (i) afford the Pledgor
any right to issue Entitlement  Orders with respect to any Security  Entitlement
to the Pledge Securities or Collateral  Investments or any Securities Account in
which any such  Security  Entitlement  may be carried,  or otherwise  afford the
Pledgor control of any such Security  Entitlement or (ii) otherwise give rise to
any rights of the  Pledgor  with  respect  to the  Collateral  Investments,  any
Security  Entitlement  thereto  or any  Securities  Account  in  which  any such
Security Entitlement may be carried,  other than the Pledgor's rights under this
Pledge Agreement as the beneficial owner of Collateral pledged to and subject to
the exclusive dominion and control (including, without

                                       12

<PAGE>

limitation, Securities Control) (except as expressly provided in this Section 6)
of the Trustee in its capacity as such (and not as a  Securities  Intermediary).
The Pledgor acknowledges,  confirms and agrees that the Trustee holds a Security
Entitlement to the Collateral  Investments  solely as trustee for the Holders of
the Notes and not as a Securities Intermediary for the Pledgor.

                  SECTION 7. Representations and Warranties.  The Pledgor hereby
represents and warrants, as of the date hereof, that:

                  (a) The  execution  and  delivery  by the  Pledgor of, and the
         performance  by the  Pledgor  of its  obligations  under,  this  Pledge
         Agreement  will not  violate any  provision  of  applicable  law or the
         Articles of  Incorporation  or By-laws of the  Pledgor or any  material
         agreement  or  instrument  binding  upon  the  Pledgor  or  any  of its
         subsidiaries or any judgment, order or decree of any governmental body,
         agency or court  having  jurisdiction  over the  Pledgor  or any of its
         subsidiaries,  or result in the creation or  imposition  of any Lien on
         any assets of the Pledgor,  except for the security  interests  granted
         under this Pledge  Agreement.  No consent,  approval,  authorization or
         order of, or  qualification  with, any  governmental  body or agency is
         required  (i) for the  performance  by the  Pledgor of its  obligations
         under this Pledge Agreement,  (ii) for the pledge by the Pledgor of the
         Collateral  pursuant to this Pledge  Agreement  or (iii) except for any
         such  consents,  approvals,  authorizations  or orders  required  to be
         obtained  by the Trustee (or the  Holders)  for reasons  other than the
         consummation  of this  transaction,  for the exercise by the Trustee of
         the rights  provided  for in this Pledge  Agreement  or the remedies in
         respect of the Collateral pursuant to this Pledge Agreement.

                  (b) The  Pledgor is the  beneficial  owner of the  Collateral,
         free and clear of any Lien or claims  of any  person or entity  (except
         for the security  interests  granted under this Pledge  Agreement).  No
         financing  statement  covering the Pledgor's interest in the Collateral
         is on file in any public office other than the financing statements, if
         any, filed pursuant to this Pledge Agreement.

                  (c) This Pledge  Agreement has been duly  authorized,  validly
         executed  and   delivered  by  the  Pledgor  and   (assuming   the  due
         authorization and valid execution and delivery of this Pledge Agreement
         by the Trustee and  enforceability  of the Pledge Agreement against the
         Trustee in  accordance  with its terms and the  provisions of the TIA,)
         constitutes a valid and binding  agreement of the Pledgor,  enforceable
         against the Pledgor in accordance with its terms,  except as (i) may be
         limited by bankruptcy, insolvency, fraudulent

                                       13

<PAGE>
         conveyance, preference, reorganization,  moratorium or similar laws now
         or hereafter in effect  relating to or affecting the rights or remedies
         of creditors generally, (ii) the availability of equitable remedies may
         be limited by equitable  principles  of general  applicability  and the
         discretion  of the court  before which any  proceeding  therefor may be
         brought, (iii) the exculpation provisions and rights to indemnification
         hereunder may be limited by U.S.  federal and state securities laws and
         public policy considerations and (iv) the waiver of rights and defenses
         contained in Section 13(b),  Section 17.11 and Section 17.15 hereof may
         be limited by applicable law.

                  (d) Upon the  delivery  to the  Trustee of the  Collateral  in
         accordance  with the  procedures  described  in Section 3 and Section 4
         hereof,  the  pledge  of  and  grant  of a  security  interest  in  the
         Collateral  securing the payment of the  Obligations for the benefit of
         the Trustee and the Holders of the Notes will constitute a valid, first
         priority,  perfected security interest in such Collateral (except, with
         respect to Proceeds,  only to the extent  permitted by Section 9-306 of
         the UCC),  enforceable as such against all creditors of the Pledgor and
         any persons  purporting  to  purchase  any of the  Collateral  from the
         Pledgor,  except in each case as enforcement may be affected by general
         equitable  principles  (whether considered in a proceeding in equity or
         at law) and other than as permitted by the Indenture.

                  (e) There are no legal or governmental proceedings pending or,
         to the  best of the  Pledgor's  knowledge,  threatened,  to  which  the
         Pledgor  or any of its  subsidiaries  is a party or to which any of the
         properties  of the Pledgor or any of its  subsidiaries  is subject that
         would  materially  adversely affect the power or ability of the Pledgor
         to perform its obligations under this Pledge Agreement or to consummate
         the transactions contemplated hereby.

                  (f) The  pledge  of the  Collateral  pursuant  to this  Pledge
         Agreement  is  not  prohibited  by  law  or   governmental   regulation
         (including, without limitation,  Regulations G, T, U and X of the Board
         of Governors of the Federal Reserve System) applicable to the Pledgor.

                  (g) No Event of Default (as defined herein) exists.

                  SECTION 8. Further Assurances. The Pledgor will, promptly upon
the  request  by the  Trustee  (which  request  the  Trustee  may  submit at the
direction  of the Holders of a majority  in  aggregate  principal  amount of the
Notes  then  outstanding),  execute  and  deliver  or cause to be  executed  and
delivered,  or use its  reasonable  best  efforts to procure,  all  assignments,
instruments and other documents, all in form and

                                       14
<PAGE>
substance reasonably satisfactory to the Trustee, deliver any instruments to the
Trustee and take any other  actions that are  necessary or desirable to perfect,
continue  the  perfection  of, or protect the first  priority  of the  Trustee's
security  interest in and to the Collateral,  to protect the Collateral  against
the rights,  claims or interests of third  persons  (other than any such rights,
claims or interests  created by or arising through the Trustee) or to effect the
purposes  of this Pledge  Agreement.  The Pledgor  also  hereby  authorizes  the
Trustee to file any  financing or  continuation  statements in the United States
with  respect to the  Collateral  without the  signature  of the Pledgor (to the
extent  permitted  by  applicable  law).  The  Pledgor  will  promptly  pay  all
reasonable costs incurred in connection with any of the foregoing within 60 days
of receipt of an invoice  therefor.  The  Pledgor  also  agrees,  whether or not
requested  by the  Trustee,  to use its  reasonable  best  efforts to perfect or
continue the  perfection  of, or to protect the first priority of, the Trustee's
security  interest  in and to the  Collateral,  and to  protect  the  Collateral
against the rights,  claims or interests of third  persons  (other than any such
rights, claims or interests created by or arising through the Trustee).

                  SECTION 9.  Covenants.  The Pledgor  covenants and agrees with
the  Trustee  and the  Holders of the Notes that from and after the date of this
Pledge Agreement until the Termination Date:

                  (a)  that it will not (i) (and  will not  purport  to) sell or
         otherwise  dispose of, or grant any option or warrant  with respect to,
         any of the  Collateral nor (ii) create or permit to exist any Lien upon
         or with  respect  to any of the  Collateral  (except  for the  security
         interests  granted under this Pledge  Agreement and any Lien created by
         or  arising  through  the  Trustee)  and at all times  will be the sole
         beneficial owner of the Collateral; and

                  (b)  that  it  will  not  (i)  enter  into  any  agreement  or
         understanding  that  restricts  or  inhibits or purports to restrict or
         inhibit the Trustee's rights or remedies hereunder,  including, without
         limitation,  the  Trustee's  right to sell or otherwise  dispose of the
         Collateral or (ii) fail to pay or discharge any tax, assessment or levy
         of any  nature  with  respect  to the  Collateral  not later  than five
         Business  Days  prior  to the  date  of any  proposed  sale  under  any
         judgment, writ or warrant of attachment with respect to the Collateral.

                  SECTION  10.  Power of  Attorney.  In  addition  to all of the
powers granted to the Trustee pursuant to the Indenture, subject to the terms of
this Pledge  Agreement,  the Pledgor hereby appoints and constitutes the Trustee
as the Pledgor's  attorney-in-fact (with full power of substitution) to exercise
to the fullest extent  permitted by law all of the following  powers upon and at
any time after the occurrence and during the continuance of an Event of Default:
(a) collection of proceeds of any

                                       15

<PAGE>
Collateral;  (b) conveyance of any item of Collateral to any purchaser  thereof;
(c) giving of any notices or recording of any Liens under Section 3 hereof;  and
(d) paying or discharging  taxes or Liens levied or placed upon the  Collateral,
the legality or validity thereof and the amounts necessary to discharge the same
to be determined by the Trustee in its reasonable discretion,  and such payments
made by the  Trustee to become  part of the  Obligations  of the  Pledgor to the
Trustee,  due and payable immediately upon demand. The Trustee's authority under
this Section 10 shall include, without limitation,  the authority to endorse and
negotiate any checks or instruments  representing  proceeds of Collateral in the
name of the Pledgor,  execute and give receipt for any  certificate of ownership
or  any  document  constituting  Collateral,  transfer  title  to  any  item  of
Collateral,  sign the Pledgor's name on all financing  statements (to the extent
permitted  by  applicable  law)  or any  other  documents  deemed  necessary  or
appropriate by the Trustee in its reasonable discretion to preserve,  protect or
perfect the security  interest in the Collateral and to file the same,  prepare,
file and sign the  Pledgor's  name on any notice of Lien,  and to take any other
actions  arising  from or incident to the powers  granted to the Trustee in this
Pledge  Agreement.  This power of  attorney is coupled  with an interest  and is
irrevocable  by  the  Pledgor  but  shall  remain  in  effect  only  during  the
continuance of an Event of Default.

                  SECTION 11. No  Assumption  of Duties;  Reasonable  Care.  The
rights and powers granted to the Trustee hereunder are being granted in order to
preserve and protect the security interest of the Trustee and the Holders of the
Notes in and to the Collateral  granted hereby and shall not be interpreted  to,
and shall not impose any duties on, the Trustee in  connection  therewith  other
than those expressly  provided herein or imposed under applicable law. Except as
provided by applicable law or by the  Indenture,  the Trustee shall be deemed to
have exercised reasonable care in the custody and preservation of the Collateral
in its possession if the Collateral is accorded treatment substantially equal to
that which the Trustee accords similar  property held by the Trustee for similar
accounts, it being understood that the Trustee in its capacity as such shall not
have any  responsibility  for (a)  ascertaining or taking action with respect to
calls,  conversions,  exchanges,  maturities  or other  matters  relative to any
Collateral,  whether or not the  Trustee has or is deemed to have  knowledge  of
such matters,  (b) taking any  necessary  steps to preserve  rights  against any
parties with respect to any  Collateral or (c) investing or  reinvesting  any of
the  Collateral,  provided,  however,  that  nothing  contained  in this  Pledge
Agreement  shall  relieve the Trustee of any  responsibilities  as a  Securities
Intermediary under applicable law.

                  SECTION 12.  Indemnity.  The  Pledgor  shall  indemnify,  hold
harmless and defend the Trustee and its directors,  officers,  attorneys-in-fact
and  agents  from  and  against  any  and  all  claims,  actions,   obligations,
liabilities  and expenses,  including  reasonable  legal fees,  arising from the
Trustee's performance as Trustee under this

                                       16

<PAGE>

Pledge  Agreement,  except to the extent  that such claim,  action,  obligation,
liability  or expense  arises from the bad faith,  gross  negligence  or willful
misconduct of such indemnified  person.  The provisions of this Section 12 shall
survive  termination of this Pledge Agreement and the resignation and removal of
the Trustee for a period of three (3) years after the Termination Date.

                  SECTION 13.  Remedies  upon Event of Default.  If any Event of
Default  under the  Indenture  or breach of the terms  hereof (any such Event of
Default or breach  being  referred to in this Pledge  Agreement  as an "Event of
Default") shall have occurred and be continuing:

                  (a) The Trustee  and the  Holders of the Notes shall have,  in
         addition to all other rights  given by law or by this Pledge  Agreement
         or the  Indenture,  all of the rights and remedies  with respect to the
         Collateral of a secured party under the UCC then in effect in the State
         of New  York  and the  State of  Maryland.  Any sale of the  Collateral
         conducted in conformity with reasonable  commercial practices of banks,
         insurance companies,  commercial finance companies,  or other financial
         institutions  disposing of property  similar to the Collateral shall be
         deemed to be commercially  reasonable.  Any  requirements of reasonable
         notice shall be met if such notice is mailed to the Pledgor as provided
         in Section  17.1  hereof at least ten (10) days  before the time of the
         sale or disposition. The Trustee or any Holder of Notes may, in its own
         name or in the name of a designee or nominee, buy any of the Collateral
         at any public sale and, if permitted by applicable  law, at any private
         sale. All expenses  (including  court costs and  reasonable  attorneys'
         fees,  expenses and  disbursements) of, or incident to, the enforcement
         of any of the provisions  hereof shall be recoverable from the proceeds
         of the sale or other disposition of the Collateral.

                  (b) The  Pledgor  further  agrees to use its  reasonable  best
         efforts  to do or  cause  to be  done  all  such  other  acts as may be
         necessary  to make  such  sale or  sales of all or any  portion  of the
         Collateral  pursuant  to this  Section  13  valid  and  binding  and in
         compliance with any and all other  applicable  requirements of law. The
         Pledgor further agrees that a breach of any of the covenants  contained
         in this Section 13 will cause irreparable injury to the Trustee and the
         Holders of the Notes,  that the  Trustee  and the  Holders of the Notes
         have no  adequate  remedy at law in respect of such  breach  and,  as a
         consequence,  that each and every covenant contained in this Section 13
         shall be specifically  enforceable against the Pledgor, and the Pledgor
         hereby  waives and agrees not to assert any defenses  against an action
         for specific performance of such covenants except for a defense that no
         Event of Default has occurred.

                                       17
<PAGE>
                  SECTION 14.  Expenses.  The Pledgor will, upon demand,  pay to
the Trustee the amount of any and all reasonable  expenses,  including,  without
limitation,  the reasonable  fees,  expenses and  disbursements  of its counsel,
experts  and agents  retained  by the  Trustee,  that the  Trustee  may incur in
connection with (a) the review,  negotiation and  administration  of this Pledge
Agreement,  (b) the custody or preservation of, or the sale of, collection from,
or  other  realization  upon,  any  of  the  Collateral,  (c)  the  exercise  or
enforcement  of any of the rights of the  Trustee  and the  Holders of the Notes
hereunder  or (d) the  failure by the  Pledgor to perform or observe  any of the
provisions hereof.

                  SECTION  15.  Security  Interest  Absolute.  All rights of the
Trustee and the Holders of the Notes and security interests  hereunder,  and all
obligations  of the  Pledgor  hereunder,  shall be  absolute  and  unconditional
irrespective of:

                  (a) any lack of validity or enforceability of the Indenture or
         any other agreement or instrument relating thereto;

                  (b) any change in the time,  manner or place of payment of, or
         in any  other  term of,  all or any of the  Obligations,  or any  other
         amendment  or  waiver  of or any  consent  to any  departure  from  the
         Indenture;

                  (c) any exchange,  surrender, release or non-perfection of any
         Liens on any other collateral for all or any of the Obligations; or

                  (d) to the  extent  permitted  by  applicable  law,  any other
         circumstance  which might otherwise  constitute a defense available to,
         or a discharge of, the Pledgor in respect of the Obligations or of this
         Pledge Agreement.

                  SECTION 16. Startec Securities Intermediary's Representations,
Warranties and Covenants.  For the purposes of this Section 16 only, the Startec
Securities  Intermediary  represents  and  warrants  that  it is as of the  date
hereof,  and it agrees that for so long as it maintains the Collateral  Accounts
and acts as the  Securities  Intermediary  pursuant to this Pledge  Agreement it
shall be a Securities  Intermediary  and a FRBR Member.  In  furtherance  of the
foregoing the Startec Securities Intermediary hereby:

                  (a) represents  and warrants that it is a corporation  that in
         the ordinary course of its business maintains  securities  accounts for
         others and is acting in that capacity hereunder and with respect to the
         Pledge Account;

                                       18
<PAGE>
                  (b)  represents  and warrants  that it maintains a FRBR Member
         Securities Account with the FRBR;

                  (c)  agrees  that the  Pledge  Account  shall be an account to
         which  Financial  Assets may be  credited,  and the Startec  Securities
         Intermediary  undertakes  to treat the  Trustee as entitled to exercise
         rights that comprise  (and entitled to the benefits of) such  Financial
         Assets, and entitled to exercise the rights of an Entitlement Holder in
         the manner contemplated by the UCC;

                  (d) hereby  represents that it has not granted,  and covenants
         that so long as it acts as a Securities Intermediary hereunder it shall
         not grant,  control (including without limitation,  Securities Control)
         over or with  respect  to any  Collateral  credited  to any  Collateral
         Account from time to time to any other Person other than the Trustee.

                  (e)  covenants  that in its  capacity  as  Startec  Securities
         Intermediary  hereunder and with respect to the Collateral Accounts, it
         shall  not  take any  action  inconsistent  with,  and  represents  and
         covenants that it is not and so long as this Pledge  Agreement  remains
         in effect will not become party to any agreement the terms of which are
         inconsistent with the provisions of this Pledge Agreement;

                  (f) agrees  that any item of  property  credited to the Pledge
         Account shall be treated as a Financial Asset;

                  (g)  agrees  that  any  item  of  Collateral  credited  to any
         Collateral Account shall not be subject to any security interest,  Lien
         or right of setoff  in favor of the  Startec  Securities  Intermediary,
         except  as may be  expressly  permitted  under the  Indenture  (and the
         Startec  Securities  Intermediary  shall take such  actions as shall be
         necessary and  appropriate  to cause such  Collateral to remain free of
         any Lien or security interest of any underlying Securities Intermediary
         through which the Startec Securities Intermediary holds such Collateral
         or any Security Entitlement thereto);

                  (h)  agrees,  so  long  as it  serves  as  Startec  Securities
         Intermediary  pursuant  to  this  Pledge  Agreement,  to  maintain  the
         Collateral  Accounts  and  maintain  appropriate  books and  records in
         respect thereof in accordance with its usual  procedures and subject to
         the terms of this Pledge Agreement; and

                  (i) agrees,  with the other parties to this Pledge  Agreement,
         that the Startec Securities Intermediary's  jurisdiction,  for purposes
         of Section 8-110(e)

                                       19

         of the UCC as it  pertains  to this Pledge  Agreement,  the  Collateral
         Accounts and the Security Entitlements  relating thereto,  shall be the

                  17.3 Headings. The headings in this Pledge Agreement have been
inserted for  convenience  of reference  only,  are not to be  considered a part
hereof and shall in no way  modify or  restrict  any of the terms or  provisions
hereof.

                  17.4  Counterpart  Originals.  This  Pledge  Agreement  may be
signed in two or more  counterparts,  each of which shall be deemed an original,
but all of which shall together constitute one and the same agreement.

                  17.5  Benefits  of Pledge  Agreement.  Nothing in this  Pledge
Agreement,  express or implied, shall give to any person, other than the parties
hereto and their successors hereunder, and the Holders of the Notes, any benefit
or any legal or equitable right, remedy or claim under this Pledge Agreement.

                  17.6 Amendments, Waivers and Consents. Any amendment or waiver
of any  provision of this Pledge  Agreement  and any consent to any departure by
the Pledgor from any provision of this Pledge  Agreement shall be effective only
if made or duly given in compliance  with all of the terms and provisions of the
Indenture,  and neither the Trustee nor any Holder of Notes shall be deemed,  by
any act, delay,  indulgence,  omission or otherwise, to have waived any right or
remedy  hereunder or to have acquiesced in any Default or Event of Default or in
any breach of any of the terms and conditions hereof.  Failure of the Trustee or
any Holder of Notes to exercise,  or delay in  exercising,  any right,  power or
privilege  hereunder shall not preclude any other or further exercise thereof or
the exercise of any other right, power or privilege.  A waiver by the Trustee or
any Holder of Notes of any right or remedy  hereunder on any one occasion  shall
not be construed as a bar to any right or remedy that the Trustee or such Holder
of Notes would  otherwise have on any future  occasion.  The rights and remedies
herein provided are cumulative,  may be exercised singly or concurrently and are
not exclusive of any rights or remedies provided by law.

                  17.7 Interpretation of Agreement. All terms not defined herein
or in the  Indenture  shall have the meaning set forth in the UCC,  except where
the context otherwise requires. To the extent a term or provision of this Pledge
Agreement conflicts with the Indenture, the Indenture shall control with respect
to the subject matter of such term or provision.  Acceptance of or  acquiescence
in a course of  performance  rendered under this Pledge  Agreement  shall not be
relevant  to  determine  the meaning of this  Pledge  Agreement  even though the
accepting or  acquiescing  party had knowledge of the nature of the  performance
and opportunity for objection.

                  17.8  Continuing  Security  Interest;  Termination.  (a)  This
Pledge  Agreement  shall  create a  continuing  security  interest in and to the
Collateral  and shall,  unless  otherwise  provided in the  Indenture or in this
Pledge Agreement, remain in full

                                       21
<PAGE>
force and  effect  until the  payment in full in cash of the  Obligations.  This
Pledge Agreement shall be binding upon the Pledgor, its transferees,  successors
and  assigns,  and shall  inure,  together  with the rights and  remedies of the
Trustee hereunder,  to the benefit of the Trustee,  the Holders of the Notes and
their respective successors, transferees and assigns.

                  (b) In addition to the  provisions  of Section 6(e) hereof and
subject to the provisions of Section 17.10 hereof,  this Pledge  Agreement shall
terminate upon the payment in full in cash of the Obligations. At such time, and
subject to Section 12, the Trustee shall,  pursuant to an Issuer Order, reassign
and redeliver to the Pledgor all of the  Collateral  hereunder that has not been
sold,  disposed of,  retained or applied by the Trustee in  accordance  with the
terms  of  this  Pledge  Agreement  and the  Indenture.  Such  reassignment  and
redelivery  shall be  without  warranty  by or  recourse  to the  Trustee in its
capacity  as such,  except  as to the  absence  of any  Liens on the  Collateral
created  by or  arising  through  the  Trustee,  and shall be at the  reasonable
expense of the Pledgor.

                  17.9 Survival Provisions. All representations,  warranties and
covenants  of the Pledgor  contained  herein  shall  survive the  execution  and
delivery of this Pledge Agreement, and shall terminate only upon the termination
of this Pledge  Agreement.  The  obligations  of the Pledgor  under  Sections 14
hereof shall survive the termination of this Pledge Agreement.

                  17.10 Waivers.  The Pledgor waives  presentment and demand for
payment of any of the  Obligations,  protest  and notice of  dishonor or default
with  respect  to any of the  Obligations,  and all other  notices  to which the
Pledgor  might  otherwise be entitled,  except as otherwise  expressly  provided
herein or in the Indenture.

                  17.11 Authority of the Trustee. (a) The Trustee shall have and
be entitled to exercise all powers  hereunder that are  specifically  granted to
the Trustee by the terms  hereof,  together  with such powers as are  reasonably
incident  thereto.  The Trustee may  perform any of its duties  hereunder  or in
connection  with the  Collateral by or through  agents or employees and shall be
entitled to retain  counsel  and to act in  reliance  upon the advice of counsel
concerning  all such  matters.  Except as otherwise  expressly  provided in this
Pledge  Agreement  or the  Indenture,  neither  the  Trustee  nor any  director,
officer,  employee,  attorney  or agent of the  Trustee  shall be  liable to the
Pledgor  for any  action  taken or omitted  to be taken by the  Trustee,  in its
capacity as Trustee,  hereunder,  except for its own bad faith, gross negligence
or  willful  misconduct,  and  the  Trustee  shall  not be  responsible  for the
validity,  effectiveness  or  sufficiency  hereof or of any document or security
furnished pursuant hereto. The

                                       22
<PAGE>
Trustee and its directors,  officers,  employees,  attorneys and agents shall be
entitled  to  rely  on any  communication,  instrument  or  document  reasonably
believed by it or them to be genuine and correct and to have been signed or sent
by the proper  person or persons.  The  Trustee  shall have no duty to cause any
financing  statement  or  continuation  statement  to be filed in respect of the
Collateral.

                  (b)   The   Pledgor   acknowledges   that   the   rights   and
responsibilities  of the Trustee under this Pledge Agreement with respect to any
action  taken by the Trustee or the exercise or  non-exercise  by the Trustee of
any option,  right,  request,  judgment or other  right or remedy  provided  for
herein or resulting or arising out of this Pledge  Agreement  shall,  as between
the Trustee and the Holders of the Notes,  be governed by the  Indenture  and by
such other  agreements with respect thereto as may exist from time to time among
them,  but,  as between  the  Trustee  and the  Pledgor,  the  Trustee  shall be
conclusively  presumed  to be acting as agent for the  Holders of the Notes with
full and valid authority so to act or refrain from acting, and the Pledgor shall
not be obligated or entitled to make any inquiry respecting such authority.

                  17.12 Final Expression.  This Pledge Agreement,  together with
the  Indenture  and any other  agreement  executed in  connection  herewith,  is
intended by the parties as a final  expression  of this Pledge  Agreement and is
intended  as a complete  and  exclusive  statement  of the terms and  conditions
thereof.

                  17.13 Rights of Holders of the Notes. No Holder of Notes shall
have any  independent  rights  hereunder  other  than  those  rights  granted to
individual  Holders  of the Notes  pursuant  to  Section  607 of the  Indenture;
provided that nothing in this  subsection  shall limit any rights granted to the
Trustee under the Notes or the Indenture.

                  17.14  GOVERNING LAW;  SUBMISSION TO  JURISDICTION;  WAIVER OF
DAMAGES. (a) BOTH THIS PLEDGE AGREEMENT AND THE PLEDGE ACCOUNT SHALL BE GOVERNED
BY AND CONSTRUED IN ACCORDANCE  WITH THE LAWS OF THE STATE OF NEW YORK,  AND ANY
DISPUTE  ARISING  OUT OF,  CONNECTED  WITH,  RELATED  TO, OR  INCIDENTAL  TO THE
RELATIONSHIP ESTABLISHED BETWEEN THE PLEDGOR, THE TRUSTEE AND THE HOLDERS OF THE
NOTES IN CONNECTION WITH THIS PLEDGE AGREEMENT, AND WHETHER ARISING IN CONTRACT,
TORT, EQUITY OR OTHERWISE,  SHALL BE RESOLVED IN ACCORDANCE WITH THE LAWS OF THE

THEREIN. REGARDLESS OF ANY PROVISION IN ANY OTHER AGREEMENT, FOR PURPOSES OF THE
UCC, NEW YORK SHALL BE DEEMED TO BE THE SECURITIES  INTERMEDIARY'S  JURISDICTION
AS DEFINED IN  SECTIONS  9-  103(6)(d)  AND  8-110(e)  OF THE UCC AND THE PLEDGE

ESTABLISHED  BETWEEN  THE  PLEDGOR,  THE TRUSTEE AND THE HOLDERS OF THE NOTES IN
CONNECTION WITH THIS PLEDGE AGREEMENT, AND EACH OF THE PARTIES HERETO WAIVES ANY
OBJECTION  THAT IT MAY HAVE TO THE LAYING OF VENUE,  INCLUDING  ANY  PLEADING OF
FORUM NON  CONVENIENS,  WITH  RESPECT TO ANY SUCH ACTION AND WAIVES ANY RIGHT TO
WHICH IT MAY BE ENTITLED ON ACCOUNT OF PLACE OF RESIDENCE OR DOMICILE.

                  (c) THE PLEDGOR AGREES THAT THE TRUSTEE SHALL, IN ITS CAPACITY
AS TRUSTEE OR IN THE NAME AND ON BEHALF OF ANY HOLDER OF NOTES,  HAVE THE RIGHT,
TO THE EXTENT PERMITTED BY APPLICABLE LAW, TO PROCEED AGAINST THE PLEDGOR OR THE
COLLATERAL  IN A COURT IN ANY  LOCATION  REASONABLY  SELECTED IN GOOD FAITH (AND
HAVING PERSONAL OR IN REM  JURISDICTION  OVER THE PLEDGOR OR THE COLLATERAL,  AS
THE CASE MAY BE) TO ENABLE THE  TRUSTEE TO  REALIZE  ON SUCH  COLLATERAL,  OR TO
ENFORCE A JUDGMENT  OR OTHER COURT ORDER  ENTERED IN FAVOR OF THE  TRUSTEE.  THE
PLEDGOR AGREES THAT IT WILL NOT ASSERT ANY COUNTERCLAIMS, SETOFFS OR CROSSCLAIMS
IN ANY  PROCEEDING  BROUGHT BY THE  TRUSTEE TO  REALIZE ON SUCH  PROPERTY  OR TO
ENFORCE A JUDGMENT OR OTHER COURT ORDER IN FAVOR OF THE TRUSTEE, EXCEPT FOR SUCH
COUNTERCLAIMS, SETOFFS OR

                                       24
<PAGE>

(EXCEPT AS OTHERWISE  PROVIDED IN THIS PLEDGE  AGREEMENT OR THE  INDENTURE)  THE
TRUSTEE IN ITS  CAPACITY  AS TRUSTEE  SHALL HAVE ANY  LIABILITY  TO THE  PLEDGOR

PLEDGOR  IN  CONNECTION  WITH,  ARISING  OUT OF, OR IN ANY WAY  RELATED  TO, THE
TRANSACTIONS  CONTEMPLATED  AND THE  RELATIONSHIP  ESTABLISHED  BY  THIS  PLEDGE
AGREEMENT,  OR ANY ACT,  OMISSION OR EVENT  OCCURRING IN  CONNECTION  THEREWITH,
UNLESS IT IS DETERMINED BY A FINAL AND NONAPPEALABLE JUDGMENT OF A COURT THAT IS
BINDING ON THE  TRUSTEE OR SUCH  HOLDER OF NOTES,  AS THE CASE MAY BE, THAT SUCH
LOSSES WERE THE RESULT OF ACTS OR  OMISSIONS  ON THE PART OF THE TRUSTEE OR SUCH
HOLDERS OF NOTES, AS THE CASE MAY BE,  CONSTITUTING BAD FAITH,  GROSS NEGLIGENCE
OR WILLFUL MISCONDUCT.

                  (e) TO THE EXTENT  PERMITTED  BY  APPLICABLE  LAW, THE PLEDGOR
WAIVES THE POSTING OF ANY BOND  OTHERWISE  REQUIRED OF THE TRUSTEE OR ANY HOLDER
OF NOTES IN  CONNECTION  WITH ANY JUDICIAL  PROCESS OR PROCEEDING TO ENFORCE ANY
JUDGMENT OR OTHER COURT ORDER PERTAINING TO THIS PLEDGE AGREEMENT OR ANY RELATED
AGREEMENT OR DOCUMENT ENTERED IN FAVOR OF THE TRUSTEE OR ANY HOLDER OF NOTES, OR
TO ENFORCE BY SPECIFIC  PERFORMANCE,  TEMPORARY RESTRAINING ORDER OR PRELIMINARY

                            FIRST UNION NATIONAL BANK

                              OFFICER'S CERTIFICATE

                  Pursuant to Section 3(d) of the Collateral Pledge and Security
Agreement  (the "Pledge  Agreement")  dated as of May 21, 1998  between  Startec
Global  Communications  Corporation,  a Maryland corporation (the "Pledgor") and
First  Union  National  Bank,  trustee  (the  "Trustee")  for the holders of the
Pledgor's 12% Senior Notes due 2008, the undersigned  officer of the Trustee, on
behalf of the Trustee, makes the following certifications to the Pledgor and the
Initial  Purchasers.  Capitalized  terms used and not defined in this  Officer's
Certificate have the meanings set forth or referred to in the Pledge Agreement.

                  1.  Substantially  contemporaneously  with the  execution  and
delivery of this Officer's  Certificate,  the Trustee has  established  the Cash
Collateral   Account  and  the  Pledge  Account  with  the  Startec   Securities
Intermediary.  The  Trustee  is  the  entitlement  holder  with  respect  to the
financial  assets on deposit in the Cash  Collateral  Account and has acquired a
security  entitlement with respect to such financial assets. The Trustee will be
the entitlement holder with respect to the Pledged Securities and will acquire a
security  entitlement  with respect to the Pledged  Securities  when the Startec
Securities Intermediary indicates by book entry that the Pledged Securities have
been  credited to the Pledge  Account.  Without  limiting the  generality of the
foregoing,  the  Pledge  Account,  the  Cash  Collateral  Account,  the  Pledged
Securities  and  the  other  Collateral  are  not,  and the  Trustee's  security
entitlement  with  respect  to the  financial  assets  on  deposit  in the  Cash
Collateral  Account  is not,  to the actual  knowledge  of the  corporate  trust
officer having responsibility for the administration of this Indenture on behalf
of the Trustee,  subject to any Lien  granted by or to or arising  through or in
favor of any Securities Intermediary (including, without limitation, the Startec
Securities Intermediary, or the Federal Reserve Bank of Richmond).

                  2. The Trustee has not caused or permitted the Cash Collateral
Account or its  Security  Entitlement  with respect to the  financial  assets on
deposit in the Cash Collateral  Account to become subject to any Lien created by
or arising through the Trustee.

                  IN WITNESS WHEREOF,  the undersigned officer has executed this
Officer's  Certificate on behalf of First Union National Bank, Trustee this 21st
day of May, 1998.

                   Nortel, and in the event of such return,  neither party shall
                   have  any  further  liabilities  or  obligations  under  this
                   Agreement on account of such  infringement or return,  except
                   Nortel shall refund the  depreciated  value of such  Products
                   carried on Buyer's books at the time of such return, less any

                   claim,  or  proceeding  described  in Section  10.2 shall not
                   apply with respect to Products which are (a)  manufactured or

                   special instruction  furnished by Buyer, (b) used by Buyer in

                   solely  by  Buyer  through  the  permitted  use  of  Products
                   furnished  hereunder,  provided the infringement  arises from
                   such  combination or the use thereof.  Buyer shall  indemnify
                   and hold Nortel  harmless  against any loss,  cost,  expense,
                   damage,  settlement or other  liability,  including,  but not
                   limited to,  attorneys' fees, which may be incurred by Nortel
                   with respect to any suit,  claim, or proceeding  described in
                   this Section 10.6.

          10.7     Notwithstanding the above, Nortel shall have no obligation or
                   liability with regard to any patent infringement suit, claim,
                   or proceeding  that may be made or brought  against Buyer (i)
                   alleging  that  method  of use  claims  in  such  patent  are
                   infringed by any service  offering and/or by any use by Buyer
                   of Products furnished hereunder to make such service offering
                   available or (ii) resulting in a settlement payment, or award
                   of damages, or accounting of profits,  where such settlement,
                   award,  or  accounting  is based on the  revenues  or profits
                   earned or other value  obtained by Buyer from its use of such
                   Products  and/or is based on the lost  revenues or profits of
                   third parties arising from Buyer's use of such Products.

          10.8     If Nortel  determines that any Products are or may become the
                   subject of a suit,  claim,  or  proceeding  as  described  in
                   Section  10.7,  Nortel may provide  Buyer with notice to that
                   effect.  Nortel shall have no liability to Buyer  pursuant to
                   Section  10.2,  10.4,  or 10.5 with respect to Buyer's use of
                   such  Products  which occurs  subsequent  to such notice.  In
                   addition  to its  obligations  pursuant to Section  10.3,  if
                   Buyer  becomes aware that any Products may become the subject
                   of any such suit,  claim, or proceeding  before receiving any
                   such notice from  Nortel,  Buyer  shall  provide  Nortel with
                   notice to that effect.

          10.9     After receipt of notice from Nortel pursuant to Section 10.8,
                   Buyer   shall  have  the  option  to  return  to  Nortel  the
                   applicable  Products  identified  in such  notice  and Nortel
                   shall refund the  depreciated  value (as carried on the books

          material,   service   affecting   nonconformance   to  the  applicable
          Specifications,  provided  that  Buyer  shall  have paid all  Software
          support fees specified in the applicable  Product  Attachment.  If the
          Software  fails to so function,  Buyer's sole remedy and Nortel's sole

          through,  at Nortel's  option,  the replacement or modification of the
          Software or such other actions as Nortel  reasonably  determines to be
          appropriate.

5.        The  obligations  and remedies set forth in Sections 1, 2, and 3 above
          shall be  conditional  upon:  the Equipment not having been altered or
          repaired,  the Software not having been modified, and the Products not
          having  been  installed  outside  the  United  States;  any  defect or
          nonconformance  not being the result of  mishandling,  abuse,  misuse,
          improper  storage,   improper   performance  of  installation,   other
          services, maintenance or operation by other than Nortel (including use
          in  conjunction  with  any  product  which  is  incompatible  with the
          applicable Equipment or Software or of inferior  performance),  and/or

          written  notice of the defect  having been given to Nortel  within the
          applicable Warranty Period.

6.        The  performance  by Nortel  of any of its  obligations  described  in
          Section  2 or 3 of this  Exhibit  D shall not  extend  the  applicable
          Warranty  Period  except to the  extent  specified  in the  applicable
          Product Attachment.

7.        Upon  expiration  of the  applicable  Warranty  Period  for  Equipment
          furnished hereunder, repair and replacement Service for such Equipment
          shall be available to Buyer from Nortel in  accordance  with  Nortel's
          then-current terms, conditions and prices. Such repair and replacement
          Service  and  notice  of  any   discontinuance   of  such  repair  and
          replacement  Service shall be available for a minimum period set forth
          in the Product Attachment applicable to such Equipment. This provision
          shall survive the expiration of this Agreement.

8.        Unless  Nortel  elects to repair or  replace  defective  Equipment  at
          Buyer's facility, all Equipment to be repaired or replaced, whether in
          or out of  warranty,  shall be  packed  by Buyer  in  accordance  with
          Nortel's  instructions stated in the applicable Product Attachment and
          shipped at Buyer's  expense and risk of loss to a location  designated
          by  Nortel.  Replacement  Equipment  shall  be  returned  to  Buyer at

          invoice Buyer for the replacement Equipment at the then  current price
          in effect therefor.

9.        With respect to any Vendor Item  furnished by Nortel to Buyer pursuant
          to this  Agreement,  Nortel  shall  assign to Buyer on a  nonexclusive
          basis any warranty granted by the party that supplied such Vendor Item
          to Nortel to the extent of Nortel's right to do so.

10.       Neither Nortel nor Nortel's suppliers, as appropriate,  shall have any
          responsibility   for  warranties  offered  by  Buyer  to  any  of  its
          customers.  Buyer shall indemnify  Nortel and Nortel's  suppliers,  as
          appropriate, with respect thereto.

               Date,  subject to the availability  from Nortel of the applicable
               Products and/or Services after such period of delay.

       d.      Except as set forth in Sections  5.b.  and 5.c.  of this  Product
               Attachment,  any change to an Order after Nortel's  acceptance of
               such Order shall  require  written  agreement of Nortel and Buyer
               upon a written change to the Order  ("Change  Order") which shall
               reference the original  Order and be executed by the parties.  No
               such changes shall be  implemented  until the  applicable  Change
               Order has been executed by the parties.

       e.      With  respect to each Order for  Products  which is  accepted  by
               Nortel,  Buyer may make a written  request at least  ninety  (90)
               days prior to the scheduled  shipment date of such Products for a
               change   ("Change")   consisting   of  certain   addition(s)   or
               deletion(s)  to such  Products.  After  receipt of such  request,
               Nortel  shall  submit a Job  Change  Order  ("JCO")  to Buyer for
               Buyer's  approval  with respect to the requested  Change,  except
               that Nortel  shall be under no  obligation  to submit such JCO to
               Buyer if  Nortel  determines  that the Price  applicable  to such
               Order would be reduced by more than ten percent (10%) as a result
               of the implementation of the Change. Each JCO shall state whether
               the requested  Change shall increase or decrease the Price and/or
               time required by Nortel for any aspect of its  performance  under
               the Agreement  with respect to such Order.  Buyer shall accept or
               reject  the JCO in  writing  within  ten  (10)  days  of  receipt
               thereof.  Failure  of the Buyer to  accept  or reject  the JCO in
               writing as described above shall be deemed a rejection of the JCO
               by Buyer.  In the event an accepted  JCO  involves  the return to
               Nortel  of  any  Equipment   which  shall  have  been  previously
               delivered  to Buyer,  Nortel may  invoice and Buyer shall pay the
               transportation costs and Nortel's then- current restocking charge
               for the returned Equipment.

       f.      Any  increase or  decrease in the Price with  respect to an Order
               hereunder  which is  occasioned by an accepted JCO shall be added
               to or  subtracted  from,  as  applicable,  the amount of the last
               payment due pursuant to Section 6 with respect to such Order.

       g.      If Buyer rejects a proposed JCO, then the rights and  obligations
               of the parties with respect to the applicable  Order shall not be
               subject to Buyer's requested  Changes,  provided that Buyer shall
               promptly  pay to  Nortel  all of  Nortel's  additional  costs and
               expenses incurred hereunder in accordance with Buyer's

               Changes,  and Nortel  shall be  entitled to an  extension  of the
               dates for  performance  of its  obligations  with  respect to the

       the parties with  respect to  testing,  turnover  and  acceptance  of any
       Products o furnished  hereunder  and  installed  by Nortel shall be as
       follows:

       a.      Nortel  shall  provide  Buyer with five (5) days  written  notice
               prior  to  commencing  final  commissioning  and  testing  of any
               Products  installed  by Nortel.  Buyer shall cause an  authorized
               representative   of  Buyer  to  be  present  at  the   applicable
               Installation  Site  to  witness  such  final   commissioning  and
               testing,  provided that in the event such representative fails to
               be present for any reason,  Nortel shall not be required to delay
               performance  of  such  final   commissioning   and  testing.   In
               connection  with the  final  commissioning  and  testing  of such
               Products,  Nortel shall test the Products for conformity with the
               applicable  Acceptance  Criteria.   When  such  tests  have  been
               successfully  completed,  Nortel shall provide Buyer with written
               notice ("Turnover Notice") that the applicable Products meet such
               Acceptance  Criteria  and  are  ready  for  Buyer's  testing  for
               compliance  with such Acceptance  Criteria.  Buyer shall promptly
               complete and return to Nortel Buyer's  acknowledgment  of receipt
               of such Turnover Notice.

       b.      Following  the  Turnover  Date,  Buyer  may test  the  applicable
               Products for compliance  with the  Acceptance  Criteria using the
               tests and test  procedures  contained  in  Nortel's  Installation
               Manuals with respect to such  Products.  Within  thirty (30) days
               following the Turnover  Date of the  applicable  Products,  Buyer
               shall notify  Nortel either that Buyer has accepted such Products
               in writing using Nortel's standard Acceptance Notice form or that
               Buyer has not  accepted  such  Products in which case Buyer shall
               also   provide   Nortel  with  a  written   notice   ("Notice  of
               Deficiency")  which shall provide in reasonable detail the manner
               in which  Buyer  asserts  that the  Products  failed  to meet the
               Acceptance Criteria.  With respect to any such details with which
               Nortel agrees,  Nortel shall promptly proceed to take appropriate
               corrective action and following correction,  Buyer may retest the
               Products in accordance with this Section.  Buyer shall accept the
               Products in writing without delay when the tests pursuant to this
               Section  indicate  that the Products  comply with the  Acceptance
               Criteria.

       c.      With  respect to any points of  disagreement  between  Nortel and
               Buyer  concerning any Notice of Deficiency which are not resolved
               by Nortel and Buyer within ten (10) days after the effective date
               of the Notice of Deficiency,  Buyer, at its option, may waive any
               rights it may have on account of any such


<PAGE>



Page 9

               points of  disagreement,  or require that the disputed  points be
               resolved by arbitration.

       d.      Buyer shall notify Nortel in writing of its election  pursuant to
               Section  8.c.  not later than ten (10) days  after the  effective
               date of the  Notice  of  Deficiency,  if any,  given to Nortel by
               Buyer.  Upon  expiration of such ten (10) day period unless Buyer
               has  notified  Nortel to the  contrary,  Buyer shall be deemed to
               have  elected  to waive its right  with  respect to any points of
               disagreement  then existing between it and Nortel with respect to
               such Notice of Deficiency.

       e.      If Buyer makes  timely  election to require  arbitration  of such
               disputed  points,  the  arbitrator  shall  be  chosen  by  mutual
               agreement.  If the parties cannot agree upon an arbitrator within
               three (3) days of Buyer's election to arbitrate, each party shall
               within three (3) days  thereafter  select an  independent  and an
               unaffiliated  person to be an  arbitrator.  These two (2) persons
               selected   shall   select  a  third   person,   independent   and
               unaffiliated  with  either  party,  as a  third  arbitrator.  The
               arbitration  shall be conducted in  accordance  with the Rules of
               the American Arbitration Association,  provided, however that the
               Arbitrator(s) shall be empowered to reduce the Prices of Products
               only to the extent that the  Arbitrator(s)  find that the benefit
               of Buyer's bargain has been reduced.  The Arbitrator(s) shall not
               have any  authority to grant partial or total  rescission  unless
               the Arbitrator(s)  determine that (i) Buyer has not substantially
               received the benefit of its bargain;  and (ii) money damages will
               not provide an adequate remedy.  Judgment upon the award rendered
               by the  Arbitrator(s)  may be entered  in any Court of  competent
               jurisdiction.

                      respect to such Products;

               (iii)  Use by Buyer of such  Products or any  portion  thereof in
                      revenue-producing service at any time; or

writing  the  Grantee  of the  identity  of such  Person.  Notwithstanding  such
designation,  TC-3 only  shall be liable  towards  the  Grantee  for any and all
obligations of TC-3 as provided hereunder.

always that:

         (A)      before the payment date,  TC-3 (or its  designee,  as the case
                  may be) is  advised  by  letter or fax by the  Grantee  of the
                  amount in dispute and the nature of that dispute; and

         (B)      TC-3 (or its designee, as the case may be) shall, if requested
                  by the Grantee  within thirty (30) days of receipt of the bill
                  in dispute,  submit a replacement  bill omitting the amount in
                  dispute,  and  such  replacement  bill  shall  become  due for
                  payment on the date the  disputed  bill was due. The amount in
                  dispute  shall be  investigated  by the  Parties in good faith
                  within a thirty  (30)-day  period and if the amount in dispute
                  or part of it is found to be correct,  any necessary bill with
                  respect to such amount or part of it shall be raised and paid.
                  Notwithstanding  the  foregoing,  if on  investigation  of the
                  amount in dispute or part  thereof  such amount is found to be
                  correct,  then the  Grantee  shall  pay  interest  at the rate
                  determined  hereabove on the unpaid amount or part of it which
                  is found to be correct from the day after the due

                  including the date the outstanding payment is received by TC-3
                  (or its designee, as the case may be).

preliminary  billing basis,  appropriate  adjustments will be made in subsequent
invoices  promptly after actual costs involved are determined to insure that the
Grantee bears a proper share of the costs as provided under this Agreement.

                  encumbrances;

         (D)      not use the Capacity for any illegal, unlawful,  fraudulent or
                  unauthorized  purposes and, without limiting the generality of

                  consistent  with the  applicable  authorization,  licences and
                  permits for the  landing,  construction  and  operation of the
                  CANUS 1 System;

         (E)      use the  Capacity  in  such a way as to  avoid  degrading  the

                  Grantee or any  subgrantee,  lessee or assignee of the Grantee
                  or any  customer  of either  the  Grantee  or any  subgrantee,
                  lessee or assignee of the Grantee.

         (F)      upon at least a 24-hour  prior notice or, at any time,  if the
                  situation or circumstance  so justify,  make available to TC-3

8.4 Provision of TRANSIT  FACILITIES.  TC-3 shall use all reasonable  efforts to

                          INTELLECTUAL PROPERTY RIGHTS

9.1 No License.  No license under patents is granted by TC-3 or shall be implied
or arise by  estoppel in favour of the Grantee  with  respect to any  apparatus,
system or method  used by the  Grantee  in  connection  with the use of the MIUs
granted to the Grantee under this Agreement.

9.2 SPECIFIC INDEMNIFICATION. With respect to claims of patent infringement made
by third Persons, the Grantee will save TC-3 and the other owners of the CANUS 1

system  or method  provided  by the  Grantee,  any  subgrantee  or lessee of the

                                   ARTICLE 10

                           RECONFIGURATION OF CAPACITY

10.1  REDUCTION IN THE  CAPACITY.  In the event that the total number of MIUs on
Segment D is  reduced  below the  Initial  Assignable  Capacity,  as a result of
physical  deterioration,  or for  any  other  reason,  during  the  term of this
Agreement,  TC-3 shall give the Grantee  written notice of said decrease and the
MIUs in which the Grantee has been granted an IRU hereunder  shall be reduced in
the same proportion as the total number of MIUs assigned to TC-3 in Segment D is
reduced, except that such reductions shall not extend to fractions of half-MIUs.

10.2 Adjustment in O&M and Other Charges.  If the number of MIUs on Segment D is
decreased as provided in Section 10.1 and that operating and maintenance charges
related thereto are reduced proportionally,  the Grantee's payments with respect
to operating and  maintenance  charges for the IRU granted under this  Agreement
shall be adjusted proportionally to such reduction.

10.3     INCREASE IN COMMUNICATION CAPABILITY.

         (A)      The  communication  capability  of the  Capacity  used  by the
                  Grantee on Segment D may be increased, subject to prior notice
                  to  TC-3,  by the  use  of  equipment  which  will  make  more
                  efficient  use of such  MIUs,  provided  that  such use of the
                  Capacity does not cause an  interruption of or interference in
                  the CANUS 1 System or other systems  interconnecting  with the
                  CANUS I System.

         (B)      The Grantee  shall not be entitled to share in any increase in
                  capacity or be entitled  to credits or  reduction  in the sums
                  paid for the Capacity in the event that the Initial Assignable
                  Capacity is increased beyond 1,260 half-MIUs.

the end of the  expected  useful  life of the CANUS 1 System at 23:59  Universal
Time Coordinated,  on September 15, 2020, unless the CANUS 1 System is taken out
of service earlier, in which case this Agreement will terminate on the same date
as that of the CANUS I System.  TC-3 shall give the Grantee prompt notice of the
taking  out of  service  of the  CANUS 1 System.  In the event  that the CANUS 1
System is  extended  tacitly  beyond  its  initial  term as stated  above,  this
Agreement will continue in effect  tacitly during such extension  under the same
terms and conditions.

Notwithstanding  the termination of this Agreement,  all payment  obligations of
the Grantee for amounts still due or payable under this Agreement for the period
ending at the date of  termination  shall  survive  until full  payment  and the
Grantee shall be liable for any costs and shall benefit from any proceeds  under
Section  8.2 hereof  incurred  or  received,  as the case may be, in the case of
liquidation,  sale or  disposition  occurring  within  two (2)  years  after the
termination date.

         (A)    If the  Grantee  fails to make the  payment of any amount due to
                TC-3 (or its designee,  as the case may be) under the provisions
                of this  Agreement,  when the same  becomes  due and  payable as
                herein  provided  and such default has not been cured within ten

                effect;

         (B)    If the Grantee fails to duly observe,  perform and discharge the
                covenants,   conditions  and  obligations  on  its  part  to  be
                observed,  performed or  discharged  hereunder.  (other than the
                default  of  payment of  amounts  under any  provisions  of this
                Agreement  which is  subject  to  Subsection  12.1(a))  and such
                default has not been cured within twenty (20) days after receipt
                by the Grantee of a notice from TC-3;

         (C)    If any representation or warranty made herein shall prove at any
                time to be materially incorrect;

                or any of its affiliates  under any  telecommunications  service
                agreements  including or incorporating  the provision of CANUS 1
                capacity,  or if the Grantee  becomes  insolvent  or bankrupt or
                ceases  paying  its  debts  generally  as they  mature  or has a
                receiver,  administrative receiver or manager appointed over the
                whole  or any  part  of its  assets  or  goes  into  liquidation

13.1 Termination Upon Default.  Upon the occurrence of an Event of Default, TC-3
shall have the right to terminate this Agreement  immediately,  and, in addition
to any  other  remedies  available  hereunder,  at law or in  equity,  shall  be
entitled to repossess the Capacity  without any other notice or action,  with or
without legal process. In addition, upon occurrence of an Event of Default, TC-3
may temporarily  discontinue use of the Capacity without incurring any liability
to the Grantee, its subgrantees, its lessees or its customers, until the default
is duly cured by the Grantee to the complete satisfaction of TC-3.

13.2  Termination  After  Initial  Term.  In the event  that this  Agreement  is
continued  beyond the expected  useful life of the CANUS 1 System in  conformity
with Section 11.1, any Party may  thereafter  terminate this Agreement by giving
the other Party a notice of not less than one (1) year.

13.3 Other Remedies.   Termination of this Agreement by the Party not in default
in  accordance  with the terms  hereof  shall be without  prejudice to any other

                  arbitration  or  other  proceeding  by any  Person  containing
                  allegations   which,  if  true,   would  constitute  an  event
                  described in Subsection 14.1(a) or 14. l(b).

                                   ARTICLE 15

                               DISPUTE RESOLUTION

15.1  Arbitration.  Any  difference,  controversy  or  claim  arising  out of or
relating  to  this  Agreement,  its  interpretation  or  performance,  shall  be
considered a "Dispute".  Any Dispute shall be subject to binding  arbitration as
provided hereafter.

         (A)      The aggrieved Party shall diligently notify the other Party of
                  the occurrence of a Dispute.  The notification shall be deemed
                  diligently made if communicated to the other Party within five
                  (5) Business  Days of the  knowledge of the  occurrence of the
                  Dispute.

         (B)      Within ten (10) Business  Days  following  such  notification,
                  each Party  shall  prepare  and  disclose to the other Party a
                  brief on its position and within fifteen (15) days  thereafter
                  the parties  shall  prepare a common brief which shall contain
                  all  points of  Agreement  and all points of  disagreement  in
                  relation to the Dispute.

         (C)      Notwithstanding  Subsection 15.1(b) above, if no resolution of
                  the  Dispute has  occurred  thirty (30) days after the date on
                  which a Party has submitted the Dispute to its Chief Executive
                  Officer or a Person  appointed by him,  then the Dispute shall
                  be submitted for resolution by binding  arbitration  under the
                  Rules of  Conciliation  and  Arbitration of the  International
                  Chamber of Commerce in effect on the date the  arbitration  is
                  submitted to the tribunal of arbitration. In such event:

                  (I)  a sole arbitrator shall be appointed,  unless the parties
                       agree in a particular case within thirty (30) days of the
                       submission  of  the  Dispute  to  arbitration   that  the
                       tribunal should consist of more than one arbitrator. Such
                       arbitrator(s)  shall be knowledgeable in the field of law
                       involved;

                 (II)  the place of arbitration  shall be  Washington,  D.C. and
                       the arbitration shall be conducted in English;

               (III)   responsibility  for paying the costs of the  arbitration,
                       including the costs incurred by the parties themselves in
                       preparing   and   presenting   their   cases,   shall  be
                       apportioned by the tribunal of arbitration;

                (IV)   the award shall be rendered in the English  language  and
                       shall state the reasons upon which it is based;

                 (V)   the award of the tribunal of  arbitration  may be entered
                       and  enforced as a judgment  against a Party in any court
                       of competent  jurisdiction  or application may be made to
                       such court for a judicial  acceptance of the award and an
                       order of enforcement, as the case may be.

         (D)      Nothing in the foregoing shall prevent a Party from initiating
                  such  protective  measure  proceedings  as  are  necessary  to
                  protect any arm's length third-party rights.

         (E)      The fact that a dispute  is brought  to  arbitration  does not
                  relieve  either Party from its obligation to fulfill its other
                  covenants or  agreements as provided by this  Agreement  which
                  are not affected by the Dispute.

The receiving Party shall not disclose all or any part of the disclosing Party's
Proprietary  Information  to  any  affiliates,   agents,  officers,   directors,

Party, except on a need to know basis. Such Representatives shall be informed of

Proprietary Information of which the receiving Party is aware.

All Proprietary  Information in whatever form shall be promptly  returned by the
receiving  Party to the disclosing  Party upon written request by the disclosing
Party for any reason or upon termination of this Agreement.

Each  receiving  Party  acknowledges  that the  Proprietary  Information  of the
disclosing Party is central to the disclosing Party's business and was developed
by or for the  disclosing  Party at a significant  cost.  Each  receiving  Party

prevent any breach or threatened breach of this Agreement by the receiving Party
or any  of its  Representatives.  Such  remedy  shall  not be  deemed  to be the
exclusive  remedy  for any such  breach of this  Section  16.5,  but shall be in

Party.

None of the  Parties  shall  disclose  or make any  public  announcement  of the

TC-3 may  designate,  at its sole  discretion,  any  Person  for the  purpose of
invoicing or  receiving  payment of all costs  charged to the Grantee  hereunder
(including the Granting Price and the Segments A and C Price). TC-3 shall notify
in writing the  Grantee of the  identity of such  Person.  Notwithstanding  such
designation,  TC-3 only  shall be liable  towards  the  Grantee  for any and all
obligations of TC-3 as provided hereunder.

4.4  Disputes.  Should  any  bill or part  thereof  be under  dispute  as to its
correctness,  then interest shall not accrue on the amount of such bill provided
always that:

         (A)      before the payment date,  TC-3 (or its  designee,  as the case
                  may be) is  advised  by  letter or fax by the  Grantee  of the
                  amount in dispute and the nature of that dispute; and

         (B)      TC-3 (or its designee, as the case may be) shall, if requested
                  by the Grantee  within thirty (30) days of receipt of the bill
                  in dispute,  submit a replacement  bill omitting the amount in
                  dispute,  and  such  replacement  bill  shall  become  due for
                  payment on the date the  disputed  bill was due. The amount in
                  dispute  shall be  investigated  by the  Parties in good faith
                  within a thirty  (30)-day  period and if the amount in dispute
                  or part of it is found to be correct,  any necessary bill with
                  respect to such amount or part of it shall be raised and paid.
                  Notwithstanding  the  foregoing,  if on  investigation  of the
                  amount in dispute or part  thereof  such amount is found to be
                  correct,  then the  Grantee  shall  pay  interest  at the rate
                  determined  hereabove on the unpaid amount or part of it which
                  is found to be  correct  from the day  after  the due date for
                  payment of the  original  bill in dispute up to and  including
                  the date the  outstanding  payment is received by TC-3 (or its
                  designee, as the case maybe).

4.5  Adjustments.  In the  case of  invoices  containing  any  costs  billed  on
preliminary  billing basis,  appropriate  adjustments will be made in subsequent
invoices  promptly after actual costs involved are determined to insure that the
Grantee bears a proper share of the costs as provided under this Agreement.

         (C)      undertake  to keep the  Capacity  free of liens,  charges  and
                  other  encumbrances  (including any inchoate liens or floating
                  charges) and shall  reimburse  TC-3 (or its  designee,  as the
                  case may be), and in the event of accidental  breach,  to take
                  all steps required to discharge such liens,  charges and other
                  encumbrances;

         (D)      not use the Capacity for any illegal, unlawful,  fraudulent or
                  unauthorized  purposes and, without limiting the generality of
                  the  foregoing,  use the  Capacity,  at all time,  in a manner
                  consistent  with the  applicable  authorization,  licenses and
                  permits for the  landing,  construction  and  operation of the
                  CANTAT-3 System;

         (E)      use the  Capacity  in  such a way as to  avoid  degrading  the
                  overall   performance  of  the  CANTAT-3   System  or  causing
                  interruptions   of,  or  interference   with,   impairment  or
                  degradation  of the use of any other  capacity in the CANTAT-3
                  System.  If, after  notification by TC-3, the Grantee does not
                  take  immediate  and  effective  action  to  comply  with  its
                  obligations,  TC-3  may take  reasonable  action  required  to
                  protect the other  capacity in the  CANTAT-3  System up to and
                  including the interruption of the Capacity responsible for the
                  interruption,  interference,  impairment or  degradation.  The
                  Grantee shall bear the total cost of any  protective  measures
                  reasonably  required by TC-3 to be  installed  on the CANTAT-3
                  System  resulting  from the use of the CANTAT-3  System by the
                  Grantee or any  subgrantee,  lessee or assignee of the Grantee
                  or any  customer  of either  the  Grantee  or any  subgrantee,
                  lessee or assignee of the Grantee;

         (F)      upon at least a 24-hour  prior notice or, at any time,  if the
                  situation or circumstance  so justify,  make available to TC-3
                  the Capacity for such test and  adjustment as may be necessary
                  for the Capacity to be maintained in efficient working order.

vouchers  and  accounts  of all  costs  that it  receives  from the  Maintenance
Authority  with respect to the  maintenance,  operation and  restoration  of the
CANTAT-3 System as may be appropriate to support the billing of any O&M Charges,
Station  Costs or  restoration  costs by TC-3 and such books that relates to the
running  charges and  restoration  costs shall at all  reasonable  times be made
available  for  inspection by the Grantee for a period of two (2) years from the
date of billing.  At Grantee's  request and at Grantee's  sole cost and expense,
TC-3 will request an audit under the CANTAT-3 C&MA to the extent that it has the
right to do so.

8.2 Sharing of  Liquidation  Proceeds and Costs.  In the event of liquidation of
Segments A and C or any part  thereof  and/or  Segment F or any part  thereof by
sale or other  disposition,  TC-3 shall share with the  Grantee any  proceeds or
costs of such  liquidation,  sale or  disposition  received  or incurred by TC-3
including, without limitation, any costs related to the removal of

                                       -9-

be  incurred  by the  Grantee in  accordance  with the  Grantee's  Share of such
proceeds or costs.

8.3  Maintenance  of  the  Capacity.  TC-3  agrees  to  act  reasonably  in  the
performance of its obligations as a party to the CANTAT-3 C&MA.

8.4 Provision of Transit  Facilities.  TC-3 shall use all reasonable  efforts to
provide  suitable  digital  transit  facilities  as and when required for use in
connection  with  circuits  in the  CANTAT-3  System  so as to  provide  through
circuits between points reached via Segments A and C.

                                    ARTICLE 9

                          INTELLECTUAL PROPERTY RIGHTS

9.1 No License.  No license under patents is granted by TC-3 or shall be implied
or arise by  estoppel in favour of the Grantee  with  respect to any  apparatus,
system or method  used by the  Grantee  in  connection  with the use of the MIUs
granted to the Grantee under this Agreement.

9.2 Specific Indemnification. With respect to claims of patent infringement made
by third  Persons,  the Grantee will save TC-3 and the other  signatories to the
CANTAT-3 C&MA harmless  against claims arising out of or based on the use by the
Grantee,  in  combination  or in connection  with the Capacity,  any  apparatus,
system  or method  provided  by the  Grantee,  any  subgrantee  or lessee of the
Grantee or any customer of the Grantee, of such subgrantee or of such lessee.

                           RECONFIGURATION OF CAPACITY

10.1  Reduction in the  Capacity.  In the event that the total number of MIUs on
Segment  F is  reduced  below the  Notional  Capacity,  as a result of  physical
deterioration,  or for any other reason, during the term of this Agreement, TC-3
shall give the Grantee written notice of said decrease and the MIUs in which the
Grantee  has  been  granted  an IRU  hereunder  shall  be  reduced  in the  same
proportion as the total number of MIUs assigned to TC-3 in Segment F is reduced,
except that such reductions shall not extend to fractions of half-MIUs.

10.2 Adjustment in O&M and Other Charges.  If the number of MIUs on Segment F is
decreased as provided in Section 10.1 and that operating and maintenance charges
related thereto are reduced proportionally,  the Grantee's payments with respect
to operating and  maintenance  charges for the IRU granted under this  Agreement
shall be adjusted proportionally to such reduction.

         (A)      The  communication  capability  of the  Capacity  used  by the
                  Grantee on Segment F may be increased, subject to prior notice
                  to  TC-3,  by the  use  of  equipment  which  will  make  more
                  efficient  use of such  MIUs,  provided  that  such use of the
                  Capacity does not cause an  interruption of or interference in
                  the CANTAT-3 System or other systems  interconnecting with the
                  CANTAT-3 System.

         (B)      The Grantee  shall not be entitled to share in any increase in
                  capacity or be entitled  to credits or  reduction  in the sums
                  paid for the Capacity in the event that the Notional  Capacity
                  is increased beyond 2,016 half-MIUs.

the end of the expected  useful life of the CANTAT-3  System at 23:59  Universal
Time  Coordinated,  on October 8th, 2019 unless the CANTAT-3 System is taken out
of service earlier, in which case this Agreement will terminate on the same date

taking out of service of the  CANTAT-3  System.  In the event that the  CANTAT-3
System is  extended  tacitly  beyond  its  initial  term as stated  above,  this
Agreement will continue in effect  tacitly during such extension  under the same
terms and conditions.

Notwithstanding  the termination of this Agreement,  all payment  obligations of
the Grantee for amounts still due or payable under this Agreement for the period
ending at the date of  termination  shall  survive  until full  payment  and the
Grantee shall be liable for any costs and shall benefit from any proceeds  under

liquidation,  sale or  disposition  occurring  within  two (2)  years  after the
termination date.

                covenants,   conditions  and  obligations  on  its  part  to  be

                default has not been cured within twenty (20) days after receipt
                by the Grantee of a notice from TC-3;

                agreements  including or incorporating the provision of CANTAT-3
                capacity,  or if the Grantee  becomes  insolvent  or bankrupt or
                ceases  paying  its  debts  generally  as they  mature  or has a
                receiver,  administrative receiver or manager appointed over the
                whole  or any  part  of its  assets  or  goes  into  liquidation

15.1  Arbitration.  Any  difference,  controversy  or  claim  arising  out of or
relating  to  this  Agreement,  its  interpretation  or  performance,  shall  be

provided hereafter.

         (A)      The aggrieved Party shall diligently notify the other Party of
                  the occurrence of a Dispute.  The notification shall be deemed
                  diligently made if communicated to the other Party within five
                  (5) Business  Days of the  knowledge of the  occurrence of the

                  Rules of Conciliation

                  and  Arbitration of the  International  Chamber of Commerce in
                  effect  on  the  date  the  arbitration  is  submitted  to the
                  tribunal of arbitration. In such event:

                 (I)  a sole arbitrator  shall be appointed,  unless the parties
                      agree in a particular  case within thirty (30) days of the
                      submission of the Dispute to arbitration that the tribunal
                      should   consist  of  more  than  one   arbitrator.   Such
                      arbitrator(s)  shall be  knowledgeable in the field of law
                      involved;

                (II)  the place of arbitration shall be Washington, D.C. and the
                      arbitration shall be conducted in English;

               (III)  responsibility  for paying  the costs of the  arbitration,
                      including the costs incurred by the parties  themselves in
                      preparing and presenting their cases, shall be apportioned
                      by the tribunal of arbitration;

                (IV)  the award shall be rendered  in the English  language  and
                      shall state the reasons upon which it is based;

                 (V)  the award of the  tribunal of  arbitration  may be entered
                      and enforced as a judgment against a Party in any court of
                      competent  jurisdiction or application may be made to such
                      court for a judicial  acceptance of the award and an order
                      of enforcement, as the case may be.

         (D)      Nothing in the foregoing shall prevent a Party from initiating
                  such  protective  measure  proceedings  as  are  necessary  to
                  protect any arm's length third-party rights.

         (E)      The fact that a dispute  is brought  to  arbitration  does not
                  relieve  either Party from its obligation to fulfill its other
                  covenants or  agreements as provided by this  Agreement  which
                  are not affected by the Dispute.
